Description

Technical Field

[0001] The utility model relates to a sewage power generation system, belonging to the technical field of sewage reuse. Background Art

[0002] After the energy crisis erupted, finding alternative energy sources to reduce over-reliance on fossil fuels became a common goal for countries around the world. Renewable energy refers to energy derived from nature, such as solar, wind, geothermal, and tidal energy. Compared to nuclear and thermal power generation, which are highly polluting and potentially dangerous, renewable energy is inexhaustible and pollution-free, making renewable energy generation technology a new generation of power generation. Dalian enjoys a temperate monsoon climate with maritime characteristics, especially in the summer when sunshine is abundant, and in the winter when northeasterly winds prevail, generating abundant wind energy. Currently, power generation primarily relies on sustainable natural resources such as solar, wind, biomass, and hydropower.

[0003] Hydropower generation does not undergo chemical changes or discharge harmful substances during the process of converting water energy into electrical energy, and has little impact on the environment. Therefore, hydropower generation is a clean energy source. However, the current investment cost of hydropower generation is high, and most of them are large-scale water conservancy hubs. The initial construction period is long and is subject to many restrictions of terrain conditions. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the utility model provides a sewage power generation system. Through a series of technical processes, the utility model provides a sewage power generation system with a simple overall structure, easy assembly, low investment cost and high power generation efficiency.

[0005] The technical solution adopted by the utility model is: a sewage power generation system, which includes an impeller arranged at the water outlet of the biochemical pool, wherein blades are fixedly arranged on the impeller shaft of the impeller; one side of the impeller shaft is connected to the gear input shaft, and the end of the gear input shaft is provided with an input gear, which meshes with the output gear to drive the gear output shaft to rotate;

[0006] The gear output shaft is connected to the planetary gearbox via an output coupling, the planetary gearbox is connected to the generator via a gearbox coupling, and the power interface of the generator is connected to the power energy storage device.

[0007] The impellers are connected via an impeller shaft connecting rod.

[0008] The water outlet is provided with a detachable outlet filter.

[0009] The impeller shaft is provided with 6-12 groups of blades, and the blades are arranged on the impeller shaft at equal intervals.

[0010] The output coupling connects the gear output shaft and the transmission input shaft.

[0011] The gearbox coupling connects the gearbox output shaft and the generator shaft.

[0012] The beneficial effects of the present invention are as follows: the system includes an impeller disposed at the water outlet of the biochemical pool, wherein blades are fixedly mounted on the impeller shaft; a gear input shaft is connected to one side of the impeller shaft, and an input gear is disposed at the end of the gear input shaft. The input gear meshes with the output gear, driving the gear output shaft to rotate; the gear output shaft is connected to a planetary gearbox via an output coupling, which is then connected to a generator via a gearbox coupling. The generator's power port is connected to an electrical energy storage device. Sewage hydroelectric power generation utilizes the potential energy of sewage to convert mechanical energy and then into electrical energy. When water flows through the turbine, it rotates under the force of the water flow, driving the generator to generate electricity. The mechanical energy is converted into electrical energy, which is then transmitted to streetlights through the electrical energy storage device, substation, and power transmission and distribution equipment. Hydroelectric power generation does not consume fuel during operation, and operating and management expenses and power generation costs are far lower than those of coal-fired power plants. The outlet filter of the device removes impurities from the sewage, reducing the impact or entanglement of impurities on the impeller, preventing damage and shortening the impeller's service life. The system can achieve high-efficiency power generation with extremely low carbon emissions, meeting the requirements of the era of environmental protection and green energy.

[0017] The present invention will be described below with reference to the accompanying drawings and specific embodiments.

[0018] Figures 1 to 3A schematic diagram of a sewage power generation system is shown. The system includes an impeller 4 positioned at the outlet 2 of a biochemical tank 1. Blades 6 are fixedly mounted on an impeller shaft 7 within the impeller 4. A gear input shaft 15 is connected to one side of the impeller shaft 7. An input gear 8 is mounted at the end of the gear input shaft 15. The input gear 8 meshes with the output gear 9, driving the rotation of the gear output shaft 16. The gear output shaft 16 is connected to a planetary gearbox 11 via an output coupling 10. The planetary gearbox 11 is connected to a generator 13 via a gearbox coupling 12. The power interface of the generator 13 is connected to an electrical energy storage device 14.

[0019] In a specific embodiment, the impellers 4 are in one or more groups, and the impellers in the multiple groups are connected by an impeller shaft connecting rod 5 .

[0020] In a specific embodiment, the water outlet 2 is provided with a detachable outlet filter 3 .

[0021] In a specific embodiment, 6-12 groups of blades 6 are arranged on the impeller shaft 7 , and the blades 6 are arranged on the impeller shaft 7 at equal intervals.

[0022] In a specific embodiment, the output coupling 10 connects the gear output shaft 16 and the transmission input shaft 17 .

[0023] In a specific embodiment, the transmission coupling 12 connects the transmission output shaft 18 and the generator shaft 19 .

[0024] When operating using the above technical solution, the water outlet 2 of the biochemical pool 1 passes through the outlet filter 3, driving the impeller 4 to rotate. The outlet filter 3 is removable and filters out larger particles such as stones, preventing damage to the impeller 4. The rotation of the impeller 4 in turn drives the impeller shaft 7. Multiple impeller shafts 7 are connected by an impeller shaft coupling 5, which pools the energy from their rotation, driving the input gear 8 at the end of the gear input shaft 15. The input gear 8 meshes with the output gear 9, rotating the gear output shaft 16. The output coupling 10 connects the gear output shaft 16 to the gearbox input shaft 17, transmitting the rotation to the gearbox input shaft 17. After passing through the planetary gearbox 11, the increased speed is output by the gearbox output shaft 18. The gearbox coupling 12 then drives the generator shaft 19, causing the generator 13 to generate electricity. The generated electricity is transmitted via an electrical energy interface to the power storage device 14, which can power devices such as street lights.

[0025] The sewage treatment plant operates 24 hours a day and produces sewage every day. Sewage flows continuously from the outlet of the biochemical pool. The sewage enters the water tank, causing the impeller to rotate. The excess sewage flows downward from the overflow port. The force of the impeller rotation is first input into the gearbox, and then output to the power generation device after the gearbox changes speed. From the power generation device, it is transmitted to the power storage device, and from the power storage device, it is sent to the power supply equipment (street lights).

[0026] The sewage-to-energy system utilizes water level differences or the force of water flow to create a water turbine impeller. This impeller then drives a generator, generating electricity. The turbine's central shaft connects to a coupling, and the other end of the coupling connects to a generator, transmitting power to the generator, which then generates electricity. This system utilizes the transmission principle of planetary gears, effectively reducing the complexity of gear transmission processes. This minimizes the overall structure, making it easy to install and use, and is impact-resistant and wear-resistant, with no negative impact on pipelines during operation.

[0027] While the basic principles and key features of the present invention have been thoroughly described above through general explanations and specific embodiments, it will be readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, any such modifications or improvements that do not depart from the spirit of the present invention are intended to fall within the scope of protection claimed herein.
