Description

The utility model relates to hydropower engineering and can be used in sewer systems of residential, public and industrial buildings to generate electricity.

See USSR copyright certificate No. 811416 class. H2K 7/18, 1978

A disadvantage of the known hydroelectric unit is the difficulty of operating the cam pair, which provides feedback when adjusting the rotation speed, which is sensitive to various kinds of contaminants and the quality of the lubricant, which entails a decrease in the reliability of the hydraulic unit.

In a known hydroelectric unit comprising a generator mounted on a base rotatably about its axis and connected to it by means of a spring, and a turbine with a water conduit located on the generator shaft, the water conduit is provided with a drain valve kinematically connected to the generator.

See the description of the invention to the copyright certificate No. 1084483 cl. F03B 13/00 publ. 04/07/84 Bul. No. 13.

The disadvantage of this unit is the structural and operational complexity of the valve and water conduit. The unit cannot be used to receive energy from sewage, as it cannot be installed in the sewage systems of buildings.

A known unit of a small hydroelectric power station, see the description of the invention for copyright certificate No. 1204774 F03B 13/00 publ. Bull. No. 2 01/15/86.

The unit contains an axial turbine 1 with a guide apparatus, a bent knee and a shaft passing through it, supported by a bearing and a generator located on the knee, connected by a shaft to the turbine shaft by means of flanges, and wherein the guide apparatus is made in the form of a pipe connected to the knee, having on the inside surface spiral grooves. The bearing is made in the form of a cup with a spiral of antifriction material located inside it and enclosing the turbine shaft, the turbine shaft is equipped with a protective collar covering the bearing cup and a sealing ring made of antifriction material adjacent to the gap to the inner surface of the knee, covering the shaft and in contact with the bearing spiral and collar and elastic elements are placed between the shaft flanges.

This invention is taken as the closest prototype analogue.

The unit does not provide stable operation, as foreign objects present in the sewer drains cause clogging and shutdown of the axial turbine.

The task and the technical result are as follows: improving operational reliability and stability, simplifying the design, as compared to the prototype, it does not have an impeller that is clogged with foreign objects in the prototype.

The increase in efficiency is as follows: the proposed device allows you to not consume energy from power grids and therefore it is energy-saving;

- reduced clogging and reduced the duration of the output device to a stop.

This has been achieved by new technical solutions that are in a causal relationship with the technical result.

To achieve a technical result in a device for generating energy, which contains nozzles and an electric generator with a shaft, the salient features of the device are that the device contains a housing, inside of which an asymmetric container with a shaft is mounted. A gear sector is mounted at the output end of the shaft, meshed with the gear. A freewheel is installed coaxially with the gear on the generator shaft. The housing contains inlet and outlet nozzles.

The definition of the prototype as the closest analogue made it possible to identify a set of features essential in relation to the technical result in the claimed device, which are set forth in the formula.

Therefore, the claimed utility model meets the criterion of "novelty" under current law.

The search results show that the claimed utility model does not follow explicitly from the prior art for the specialist, since the transformations prescribed by this utility model are not identified, characterized by significant features distinctive from the prototype, aimed at achieving a technical result.

Figure 1 - schematically shows the proposed utility model. Figure 2 is a section along BB, schematically.

The proposed utility model includes a housing 1, in which an asymmetrical container 2 with an elongated wall 3 and side walls 12 is mounted. A container 2 is mounted on the shaft 4. At the output end of the shaft 4 there is a gear sector 5, which is engaged with the gear wheel 6. Coaxially with the wheel 6 on the shaft 7 is an overrunning clutch 8. The shaft 7 is connected to the generator 9. The proposed device operates as follows.

In the lower part of the sewer riser of the building mount the proposed device and connect it to the inlet pipe 10 and

outlet pipes 11 with sewer pipes (not shown). The downward flow of fluid through the pipe 10 in the direction of arrow A fills the container 2 and causes it to tip over due to the elongated wall 3 and the displaced center of gravity.

As a result, sewer drains together with foreign objects go into the outlet pipe 11 in the direction of arrow B. This achieves the technical result, which consists in operational reliability and stability, since in comparison with the indicated analogues and prototype it does not have an impeller that is clogged with foreign objects.

The overturned container 2 under the action of its own weight comes to its original position. Sector 5 performs oscillatory movements, which are converted into rotational motion of the wheel 6 and through overrunning clutch 8 and shaft 7 are transmitted to a generator 9 that generates electricity.

The simplicity of the design of the proposed utility model improves its reliability and maintenance.

Efficiency is increased by reducing clogging and reducing the duration of the output device to a stop.

Simplified manufacturing and operation of the device.

Thus, the above information indicates the possibility of using the utility model in the form described in the utility model formula using the known and proposed tools described in the application.

Therefore, the claimed device complies with the requirement "industrially applicable under applicable law." The proposed device has developed design and technological documentation.
