Description

Description: The present invention relates to a building, building or house comprising an energy production system.

We know for example from the state of the art US 4,443,707 which describes a hydroelectric power generation system which makes it possible to transform the potential energy of a water reserve into kinetic drive energy d '' a turbine coupled to an electricity generator. In this case, water stored in a tank located at a high level is released in a penstock to the electricity production turbine when an additional electric current is necessary on the network to face a peak of current consumption.

Electricity consumption is irregular and there are peaks in demand, for example at the end of the day, or in cold weather when the demand for electric heating increases or in hot weather when many air conditioning systems are in service. During peak periods, the hydroelectric energy produced can be sent to the electricity grid to meet the increase in demand, knowing that electric energy produced by other means, such as in a nuclear power plant, is difficult to adapt. Similarly, the electricity produced by soft and renewable energies (solar, wind) is produced randomly depending on weather conditions.

According to document US Pat. No. 4,443,707 outside of peak periods, electrical energy from the main distribution network is used to supply a lift pump which makes it possible to return to the tank located at a high level of the water recovered in a reservoir located at a low level so as to replenish potential energy for the next peak period.

We also know from FR 2 789 126 a device for recovering hydraulic energy for constructions of the detached house or building type comprising a first upper tank installed in height in the attic or on the roof of the construction and a second tank. lower installed in the lower part of the building, in the cellar or buried near the building. This device can be combined with solar, wind or geothermal energy recovery devices which in particular can be used to drive a water transfer pump between the lower tank and the upper tank while a turbine associated with a generator is selectively actuated by the flow of liquid circulating in a downward pipe between the upper tank and the lower tank.

DE 2 928 476 A1 describes an installation for producing electrical energy from the collection of waste water in a single-family dwelling. A collection tank is placed at the base of the house and connected by a pipe to a hydraulic wheel then to a tank located lower and allowing either an evacuation to a sewer, or recycling using a pump to the collection tank.

Starting from the principle of water storage at a high point, WO 2004 101 988 describes an electricity production system in which electricity is produced by a generator using the hydraulic load of the running water discharged to the sewage disposal column in a high-rise apartment building. The electricity obtained is used via an electrical regulator located inside the building. The hydraulically charged electrical production system comprises a removable sleeve fixed to the sewage discharge column, a water wheel fitted with a plurality of deflector panels, inserted in the sleeve, which water wheel is put in place. rotation by the waste water exiting through the column, the torque obtained being transmitted to an electric generator via a gear so as to produce electricity, an electricity tank allowing electricity to be kept, and an electric regulator used for connection to the building electrical system.

The object of the present invention is to provide a building comprising a system for producing electrical energy from a system for recovering and reusing used and / or rainwater or an inlet for drinking water. on the drinking water network of a building without distorting the function of the building and ensuring energy production with good efficiency.

According to the invention, a building, building or house comprises:

- a connection to a drinking water network, said connection to the drinking water network comprising in particular a water meter, a non-return valve and a pressure reducer, and / or

- a connection of the building to a wastewater recovery network, said connection to the wastewater network comprising a pipe recovering the wastewater to transport it to a first inspection, before discharging it into the municipal collector , and or

- a connection of the building to a rainwater recovery network, said connection to the rainwater network comprising a pipe collecting rainwater to transport it to a second manhole, before discharging it into the municipal collector , and

an electrical energy production system comprising a hydraulic turbine arranged to recover the speed of the water as kinetic energy to drive a current generator arranged to transform mechanical energy into electrical energy, said electrical energy production system further comprising a control circuit comprising a unit for coupling the energy production system to a distribution network.

CH 712 640 A1 According to the invention, the electrical energy production system comprises a hydraulic turbine arranged upstream of the pressure reducer, arranged after the water meter and / or arranged in the first and / or second manholes for the recovery of wastewater and rainwater so that the hydraulic turbine recovers the speed of the water circulating in the building according to its conventional circulation circuit, notably excluding low water circulation up and up and down through the consumption and generation of electricity.

In one embodiment, the production system comprises a speed multiplier for drinking water placed between the turbine and the generator, the turbine being arranged upstream of a pressure reducer from an inlet general building water.

According to this embodiment, the speed multiplier is in the form of a belt, a gear or a reduction in the diameter of a pipe through which the drinking water flows.

Preferably, the pipe comprises a valve arranged upstream of the turbine to allow handling without having to stop the entire network from the municipal pipe.

In one embodiment, the turbine is a reaction turbine comprising a spiral cover guiding the water radially between guide vanes and optionally fixed vanes of a wheel. According to this embodiment, the building includes a manhole, collecting rainwater and / or wastewater, said turbine being arranged in said manhole, under a sloping plate guiding the water to the turbine.

According to another embodiment, the turbine is a turbine of the action type that can be actuated by water passing through a wheel made up of two flanges joined together by a ring of blades arranged cylindrically.

According to one embodiment, the current generator, for example an alternator, converts the mechanical energy supplied by the turbine into electrical energy. The current generator can be synchronous or asynchronous depending on the case, in particular if the electrical energy produced is connected to the network, or if it is used to supply an isolated network.

Preferably, installation control and command members, in particular electrical components, are located in an electrical cabinet in the building. These are mainly switches, the regulation system, and counters.

The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, in no way limiting with reference to the schematic figures, in which:

fig. 1 shows a diagram of a system for producing electrical energy from an intake of drinking water on a drinking water network of a building;

fig. 2 shows a Francis type turbine in several views;

fig. 3 shows a building comprising a first inspection hole for wastewater and a second inspection hole for rainwater, each inspection hole comprising a device for recovering the mechanical energy of the flow of water;

fig. 4A-4C fig. 5 fig. 6A and 6B show a device for recovering the mechanical energy of the water flow arranged in a manhole in several views, the device notably comprising a Banki type turbine;

shows a side view of a rotating Banki type turbine; and show, in different sections, an ovoid water pipe with integrated factory connectors at the top of the pipe.

As illustrated in FIG. 1, a house 9 has a connection of the building to a drinking water network. The connection to the drinking water network notably includes a water meter 3, a non-return valve 5 and a pressure reducer 6. The house has an electrical energy production system 2 comprising a hydraulic turbine 1 (fig. 2). The hydraulic turbine 1 is arranged upstream of the pressure reducer 6, arranged after the water meter

3. The hydraulic turbine 1 is arranged to recover the speed of water as kinetic energy to drive a current generator arranged to transform mechanical energy into electrical energy. The electrical energy production system further comprises a control circuit comprising a unit for coupling the energy production system to a distribution network. The drinking water network comprises, in this example, a general valve 4 and a manifold 7 thus allowing the connection with all the pipes of the building, the toilets, the radiators, etc.

As illustrated in FIG. 2, the different views of the reaction hydraulic turbine 1, of the Francis type, make it possible to visualize the rotation of the reaction turbine 1 by the force of drinking water. The Francis turbine enables significant power to be developed. It consists of a spiral pipe, in the form of a spiral cover 11, which leads

CH 712 640 A1 water to a dispenser. The distributor is constituted by a series of guidelines (blades) which guide the water towards the wheel 12. The wheel 12 of the reaction turbine 1 is placed inside the distributors.

In this example, the electrical energy production system is composed of Francis turbines placed in spiral tarpaulins can be arranged in a house or a basement of a building, between the water introduction meter and the pressure reducer. This creates a rotational movement that can be transformed into electricity. This strategic position, before the pressure reducer, is linked to the fact that the reaction turbine 1 will slightly reduce the water pressure.

Thus, from the nurse 7, it is possible to supply, by distribution valves 8, all the circuits necessary for the home such as, for example, a sanitary circuit, a kitchen circuit, or a heating circuit. . Furthermore, because of the sufficiently high water inlet pressure, but whose speed is low, it is possible to multiply the rotation speed for example by means of gears to increase the rotation speed, or by example by reducing the diameter of the tubes before the device while keeping the same pressure in order to increase the flow speed and therefore also the speed of rotation. The energy produced is then transported to an electrical room and after passing through an output meter, it will be injected either to supply the house or into the public network.

As illustrated in FIG. 3, a house 9 comprises a connection of the building to a wastewater recovery network 18. The connection to the wastewater network 18 comprises a pipe 19 recovering the wastewater to transport it to a first visit look 15 The house 9 furthermore comprises a connection of the building to a rainwater recovery network 17. The connection to the rainwater network 17 comprises a pipe 20 recovering the rainwater to transport it to a second inspection manhole. 16. Each inspection manhole 15, 16 comprises an electrical energy production system 2 comprising a hydraulic turbine 10.

The principle is therefore to channel rainwater and wastewater into each of the dedicated manholes.

As illustrated in Figs. 4A, 4B and 4C, an action turbine 10, of the Banki type, is arranged in the manholes 15, 16 so that the rain and waste water which flow in each of the manholes 15, 16, cause the rotation of the action turbine 10 thus allowing the recovery of electrical energy and the evacuation of water. Each action turbine 10 arranged in each of the manholes 15,16 therefore makes it possible to produce energy. The system is removable and is composed of a plate 21 with a slope way directing the water in a channel with a "V" shaped bottom, so as to accelerate the water and thus prevent the sedimentation of detritus. In addition, the materialization of the blades would be made with a non-stick material. Then, the "Banki" type turbine 10 is arranged under the plate 21 and makes it possible to create a rotational movement by taking energy over water and thus generating a rotation and therefore also electricity.

Starting from the same principle, this energy production system can be applied as well in private parts of the type inspection rooms as for public parts. Thus, Banki type turbines placed in clear or public waste water collectors, or Francis turbines placed in the water supplies of public fountains, would generate electricity for example for public lighting, fires of signals, etc.

In existing networks, it is necessary to do a little dig to bring the energy produced from each manhole 15, 16 to the main electrical panel, in order to inject it into the public network, after passing through an exit counter.

In new constructions, it is possible to design manholes 15, 16 which would include a Banki type turbine 10 on the lower part of manhole 15, 16 and connectors 24 placed in the upper part of the pipes ( Fig. 6A and 6B) would allow the manhole 15,16 to be connected to the main electrical panel in the home. These elements would already be incorporated from factories in each prefabricated pipe element. As illustrated in fig. 5, a circular turbine of the Banki type 10 comprising propellers 22 in the form of semicircles, placed on the periphery of a wheel 23, enters into rotation by the arrival of rainwater or wastewater collected in the manholes 15, 16. This water inlet exerts a force on the propellers 22 in rotation, which is transformed into torque and mechanical power on the shaft of the turbine. The Banki turbine 10 is an action turbine having a transverse flow, the water flowing through the propellers 22 of the turbine 10. The water enters on one side of the turbine 10 and exits on the opposite side. The Banki 10 turbine is suitable for the recovery of rainwater and wastewater because it operates at low speed.

The system according to the present invention also allows the recovery of water from the groundwater which is captured by the drainage, and collected in the same pipe of rainwater.

The system is simple to set up and can be installed in new buildings as well as in existing buildings and does not alter the aesthetics of the building or the landscape. Indeed, the system is located in the technical room in the basement or in the manholes of buried visits.

Another advantage of the present invention is that it is not useful to store water, very often at a high point of a building, such as an attic, or to be dependent on the construction a water reservoir located near the building. The architecture of the house therefore remains traditional and the system has no impact on the environment.

CH 712 640 A1 The present invention relates to a building and by building should be understood in particular a building, a house, housing, offices, factories, hospitals, restaurants, hotels, schools, fountains or any another structure with a water circuit.

Another aspect of the invention relates to the production of electrical energy by any type of structure or structure with circulation of water, for example a fountain or a swimming pool comprising a filtration circuit.

For example, in the context of a fountain which is a construction made to collect water gushing from a source or supplied, under pressure or by gravity, through a conduit, a hydraulic turbine could be arranged just before the end from which water drains to produce electrical energy.

In the context of a swimming pool with filtration, water is generally sucked from the bottom of the swimming pool by a bottom drain and to the surface by skimmers and arrives at a filtration device by separate conduits each equipped with valves. The filtered water is then pumped back to the pool through discharge outlets. These discharge outlets are installed on the opposite side of the skimmers and the bottom drain, thus renewing all the water in the pool. Thus, a hydraulic turbine arranged upstream of the discharge would generate electricity.

The present invention therefore makes it possible to produce energy by grafting onto an existing water circulation structure without modifying the external appearance or having an impact on the environment.
