Description

Electric generator.

Object of the invention

The present invention relates to a generator electric, of the type that comprise a hydraulic turbine coupled to a drive shaft of an electric alternator and powered by the water that circulates through a public conduction or private

Background of the invention

At present it is of great importance the use of energy resources and exploitation of renewable or sustainable energy sources compared to others polluting or depleting energy resources and not replenish. Therefore, the growing interest in sources of renewable energy, such as solar energy, biomass or hydraulic energy. Also of special attention is the study and application of methods and systems that avoid wasting and waste of energy applied in certain services or processes, thereby reducing their consumption. So the reuse of waste, energy cogeneration or distributed production, They are reasons for developing new techniques.

The Spanish utility model is known ES1064074 "Electric generator for water pipes" of D. Jordi Aguadé Duch, in which an electric generator is described for water pipes, whether of public distribution type or private facilities. The object of this invention is to take advantage the overpressure that is usually generated in many installations and water distribution networks. Especially, at certain points in which is not necessary and the situation is bound by the requirements of other parts of the network. Thus, this overpressure is can rectify by regulators, dissipating the energy that take the water, or just waste it, when the water comes out irrigation taps or hydrants with pressure and speed excessive

In said register, mention is made of the intercalation of a rotating element susceptible to intercalary in coupling with respect to a pipe, but does not offer a concrete solution This rotating element or hydraulic turbine allows to take advantage of this energy that water carries, for example in the addresses of the users or at water distribution points determined.

Given the space needs and requirements of the installation, it is necessary that the electric generator be Simple construction, compact size and low maintenance.

Description of the invention

The electric generator, object of this invention, presents some technical peculiarities destined to offer a sustainable and easily implemented solution, enabling the exploitation of wasted resources, through a Simple construction device and simple maintenance.

Indeed, the generator of the present invention it comprises a housing provided with a closing cover, a seal intermediate, elastic material, and some screws for the tighten the cover with respect to the housing. The cover, together with the housing, define a cylindrical cavity for housing of the hydraulic turbine.

The housing has on its periphery a mouth of water inlet and a water outlet, consisting of two input and output sleeves. These sleeves present in its free end means for coupling with two branches water inlet and outlet,

At least the inlet sleeve can present a section reduction the water inlet direction to the inside the housing, which causes an acceleration of the water speed before being projected against turbine hydraulics.

The housing cover has a hole for the passage of the turbine shaft and a mechanical, pressure seal adjustable, to ensure the tightness of the inner cavity around the axis of the turbine, so that the exit of the Water by this critical point.

The housing has a foot of laterally support provided with holes or recesses for mounting some anchor bolts of the generator. Thus, it is possible to set the ground generator or other suitable support surface in the installation place

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows an elevation view partially sectioned from the electric generator.

- Figure 2 shows a profile view partial electric generator.

- Figure 3 shows a plan view of the electric generator connected to the multiplier group and to the alternator.

Preferred Embodiment of the Invention

As can be seen in the figures referenced, the electric generator is constituted by a hydraulic turbine (1) housed in a housing (2), and coupled to a gear multiplier group (3), which is associated with an electric alternator (4) to generate electricity.

The housing (2) has a cavity (21) cylindrical or hydraulic turbine housing (1), and one foot (22) of lower support, provided with holes (23) for the mounting of screws (5) anchoring the generator to the ground or other surface The housing or cavity (21) is open on the one hand, on which is a closing lid (6), between them an intermediate joint (61), of material elastic, and the housing assembly (2) being intermediate gasket (61) and closing cover (6) fixed by screws (62) of squeeze in.

The housing (2) has on its periphery a sleeve (24) with threaded means (25), in an arrangement upper, which configures a water inlet, being configured this sleeve (24) by a reduction of the section in the water inlet direction into the housing (2). To its the case (2) also has another sleeve on its periphery (26) with threaded means (27), in a lower arrangement, which configures a water outlet. In threaded media (25, 27) of both connection nozzles the two branches are associated (not represented) of passage of water in the pipeline or installation of supply.

The cover (6) of the housing (2) has a hole (63) for the passage of the shaft (11) of the hydraulic turbine (one). In said hole (63) is a mechanical seal (64) adjustable on said axis (11).

The shaft (11) is connected to an outlet input of the multiplier group (3), which presents internally gears (31) to increase the speed. The output socket of said multiplier group (3) is connected directly with the shaft (41) of the alternator (4) to transmit mechanical power with which electricity is produced.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
