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. Number 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 to copyright certificate No. 1204774 F03B 13/00 publ. Bull. No. 215.01.86

The unit contains an axial turbine with a guide apparatus, a bent knee and a shaft passing through it, supported by a bearing located on the knee and a generator connected by its shaft to the turbine shaft by means of flanges, and the guide apparatus is made in the form of a pipe connected to the knee, having spiral grooves on the inner surface. 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 objective and technical result is as follows: increasing operational reliability and stability, simplifying the design, since, compared with 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 prototype are that the device contains a housing inside which a working rotor with blades and a shaft is mounted. The output end of the shaft is connected to the generator shaft. The housing is connected to pipes for sewage. A comb is inclined in the housing.

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. Figure 3 is a view along arrow A, schematically.

The proposed utility model includes a housing 1. Inside the housing 1, a working rotor 2 is installed with blades 3 that are connected to the shaft 4. The output end of the shaft 4 is connected through a coupling 5 to the shaft 6 of the generator 7. The housing 1 contains nozzles 8, 9 for sewage. Above the rotor 2 is fixed the child 10.

In the lower part of the sewer riser of the building, the proposed device is mounted and connected to the inlet pipe 8 and the outlet pipe 9 with sewer pipes (not shown). The downward flow of sewage and storm drains through the pipe 8 in the direction of arrow B enters the housing 1 where foreign objects are separated from the liquid by a comb 10, bypassing the working rotor 2 and exit through the pipe 9 in the direction of G. The fluid enters the blades 3 of the working rotor 2 and rotates it . Torque through the shaft 4, the coupling 5, the shaft 6 is transmitted to the generator 7. This achieves a technical result that is absent in analogues such as ed. testimonial. No. 1084483 and 1204774, which consists in simplifying the design, increasing reliability, reducing the duration of the output of the device to a stop, by reducing clogging, which increases the efficiency.

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.
