Description

[Detailed description of the invention] This invention is a system that supplies constant-pressure air using the power of an engine, motor, windmill, etc., and uses the power when the supply of constant-pressure air becomes impossible due to the power supply stopping. This invention relates to a new device for supplying constant pressure air without any air pressure.

That is, the present invention is, for example, in a device in which a cylinder piston is moved by a windmill and a constant pressure air is sent to a supply destination via an air pipe, and when the windmill is operating, compressed air is stored in an air storage tank such as the one shown below, and there is no wind. When the windmill stops, the air in the air storage tank is delivered to the supply destination at a constant pressure by the gravity of the weight.

The present invention will be explained below with reference to illustrative drawings, but is not limited thereto. Fig. 1 is a longitudinal sectional front view of the device for supplying constant pressure air of the present invention;
Figure 2 is a plan view, Figure 3 is the circled A in Figure 1.
FIG.

In these figures, 14 is a concrete wall that will become the formwork of the air storage tank, 1 and 2 are airtight flexible membranes such as rubber coated cloth, 3 is a steel case for the weight, and 17 is the rubber coated cloth 1 and the weight. A fixing flange for fixing the industrial steel case 3; 4, 5, and 6 are clamping bars, base plates, and anchor bolts that are the mounting hardware for the rubberized fabrics 1 and 2; the anchor bolt 6 is attached to the formwork of the air storage tank. Concrete wall 14
will be buried in That is, the rubber-coated fabrics 1 and 2 form a closed container within the formwork of the concrete wall 14, and the volume changes with the displacement of the upper rubber-coated fabric 1. An air storage tank 20 is formed by loading and fixing the case 3.

Now, one end of the inlet tube 7 is connected to an air supply source 21 (not shown), and the other end is connected into the air storage tank 20. Air is injected into the air storage tank 20 sealed with airtight rubberized cloth 1 and 2 through the air injection pipe 7, and if the air pressure in the storage tank exceeds the set value, the steel for the weight is injected. The case 3 is lifted by this air pressure. If the air injection is continued further, the weight steel case 3 continues to rise and stops rising at the position of the steel case stopper 11. If the air injection continues and the inside of the air storage tank becomes overpressure, an air blow-off tank 8 installed, for example, in the middle of the air injection pipe 7 is used to prevent the rubber-coated fabrics 1, 2, etc. from being damaged. Exhaust pressurized air. In this state, the manual valve 9 in the air injection pipe 7 is closed to complete the storage of compressed air.

On the other hand, air is supplied from this air storage tank through air pipe 1.
Air supply is started by opening the manual valve 9 in 5. The amount of air supplied can be easily adjusted by adjusting the opening degree of the manual valve 9, the diameter of the air supply pipe 15, and incorporating a reducer into the air supply pipe. Further, the air supply pressure is constant because it is the weight of the steel case 3 for weight divided by the bottom area of the case.

Reference numeral 10 denotes a guide, which is used to move the weight steel case 3 smoothly when it moves up and down without getting hit by a concrete wall. Reference numeral 12 denotes a steel angle for lifting the steel case 3 for the weight; for example, by using this angle, the steel case 3 for the weight can be lifted by a chain block so that the rubber-coated cloths 1 and 2 can be repaired or removed. It is something. 13 is a buffer material for preventing damage to the rubberized fabrics 1 and 2 when the steel case 3 for the weight comes into contact with the concrete bottom surface of the formwork after the air inside the tank has been completely supplied; These include rubber and rubber foam. Reference numeral 16 denotes an inspection entrance (open only for inspection, normally closed) provided at the bottom of the steel case 3 to inspect the rubber-coated fabric and attachment parts inside the tank. The steel case 3 for weight serves as a weight by putting gravel, scrap lumps, etc. into the case, and by adjusting the amount of gravel, scrap lumps, etc., the weight of the weight is adjusted, and the storage and air supply air pressures are adjusted. It is possible to do so. Note that 19 is the roof.

As described above, the present invention allows constant-pressure air to be easily supplied without power, and also eliminates the risk of damage to the device.

Claims (1)

[Scope of utility model registration request] The periphery of the airtight membrane is fixed around a wall such as concrete, and the airtight flexible membrane that displaces and the airtight membrane that does not displace form a sealed container whose volume can be changed by displacement. A weight is loaded and fixed on the top of the membrane, and air is injected from the other end of the pipe communicating inside the container to fill the container, and the injected air pressure causes the weight on the top of the membrane to lift and store compressed air in a container,
On the other hand, it is possible to supply stored air at a constant pressure due to the weight of the weight from the same or different communication pipe as the pipe communicating with the inside of the container, and also to discharge the overpressure air in the sealed container. A constant pressure air supply device comprising a blow-off tank and a cushioning material for preventing damage to a flexible membrane when a weight descends and contacts the bottom of a container.
