Description

Technical Field

[0001] This invention relates to the field of water surface cleaning technology for hydropower generation, specifically to a device for cleaning pollutants from the water surface used in hydropower generation. Background Technology

[0002] Hydropower typically utilizes the potential energy of water flowing from a higher elevation to a lower elevation. This kinetic energy drives a turbine, which in turn powers a generator to produce electricity. However, the surface of these water flows often contains pollutants such as leaves, twigs, and plastic bags. To prevent these surface pollutants from damaging the power generation equipment, these impurities need to be removed.

[0003] There are generally two existing methods for cleaning up pollutants on the water surface: one is manual cleaning using ships, and the other is intercepting pollutants by setting up nets on the water surface. However, the first method is not only time-consuming and labor-intensive, but also difficult to guarantee the cleaning effect; although the second method has a higher efficiency in intercepting pollutants, when the nets become clogged, it will also affect the subsequent power generation efficiency.

[0004] Therefore, the applicant has designed a new surface pollutant cleaning device for hydropower generation to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for cleaning pollutants from the surface of water used in hydropower generation. The specific solution is as follows: A device for cleaning pollutants from the surface of water used in hydropower generation includes a guide foundation and an installation foundation fixed on both sides of the water flow. A pair of installation foundations are arranged in parallel, and a cleaning component is provided on each pair of installation foundations. The cleaning component includes a pair of parallel installation shells, each with two cylindrical sliders on its outer side. A filter plate is fixed between the pair of installation shells, and two guide rods are fixed on the front side of each installation shell corresponding to the filter plate. A rotating shaft (first and second) is rotatably mounted, with a reciprocating thread on the first shaft. The cleaning component also includes two sets of conveyor chains respectively positioned near the pair of installation shells, with each end of the first and second shafts having a... A drive sprocket is used to support two sets of conveyor plate chains; a movable plate is slidably mounted on the guide rod, and the movable plate is provided with bristles for the filter plate. The movable plate is slidably engaged with the second rotating shaft, and a reciprocating slider adapted to the reciprocating thread on the first rotating shaft is also fixed on the movable plate; multiple sets of cleaning brushes for cleaning impurities in the water are provided circumferentially on the conveyor plate chains; a pair of mounting shells are provided with drive components that are driven and engaged with the first rotating shaft on the rear side corresponding to the filter plate; a collection component for collecting impurities in the water is provided on the mounting shell corresponding to each set of conveyor plate chains; a guide groove for the slider is provided on the mounting base.

[0006] Based on the above, the collection assembly includes a support plate fixed on the mounting shell, the support plate has a hollow structure in the middle for placing the collection basket, the bottom of the collection basket has a drainage hole, and the collection basket is provided with a cleaning comb for cleaning the cleaning brush.

[0007] Based on the above, the drive assembly includes a support shaft rotatably mounted on a pair of mounting shells, the support shaft having multiple baffles along its circumference, and the support shaft engaging with the rotating shaft in a transmission connection.

[0008] Based on the above, the guide groove is inclined upwards according to the direction of water flow.

[0009] Based on the above, the material density of the mounting shell, filter plate, and moving plate is all less than that of water.

[0010] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention has the following advantages: 1. The water surface pollutant cleaning equipment for hydropower generation provided by the present invention utilizes the power of water flow as the source of power, which can achieve efficient collection and treatment of water surface pollutants, ensure water surface cleanliness, and thus ensure subsequent power generation efficiency and the safety of power generation equipment.

[0013] The technical solution of the present invention will be further described in detail below through specific embodiments. Example

[0014] like Figure 1-4 As shown, this invention provides a surface pollutant cleaning device for hydropower generation, including a guide foundation 1 and an installation foundation 2 fixed on both sides of the water flow. A pair of installation foundations 2 are arranged in parallel, and a cleaning component 3 is provided on each pair of installation foundations 2. The cleaning component 3 includes a pair of parallel installation shells 4, each with two cylindrical sliders 4-1 on its outer side. A filter plate 14 is fixed between the pair of installation shells 4, and two guide rods 13 are fixed on the front side of each pair of installation shells 4 corresponding to the filter plate 14. A rotating shaft 6 and a rotating shaft 7 are rotatably provided, with a reciprocating thread on the rotating shaft 6. The cleaning component 3 also includes two sets of conveyor chain 9 respectively located near the pair of installation shells 4, with a conveyor chain 9 at each end of the rotating shaft 6 and the rotating shaft 7. The transmission sprocket 8 carries two sets of conveyor chain 9; a movable plate 11 is slidably mounted on the guide rod 13, and the movable plate 11 is provided with bristles 11-1 for the filter plate 14. The movable plate 11 is slidably engaged with the rotating shaft 7. A reciprocating slider 12 adapted to the reciprocating thread on the rotating shaft 6 is also fixed on the movable plate 11; multiple sets of cleaning brushes 10 for cleaning impurities in the water are provided circumferentially on the conveyor chain 9; a pair of mounting shells 4 are provided with drive components that are driven and engaged with the rotating shaft 6 on the rear side of the filter plate 14; a collection component for collecting impurities in the water is provided on the mounting shell 4 corresponding to each set of conveyor chain 9; a guide groove 2-1 for the slider 4-1 is provided on the mounting base 2.

[0015] The above-mentioned collection assembly includes a support plate 18 fixed on the mounting shell 4. The support plate 18 has a hollow structure in the middle for placing the collection basket 19. The bottom of the collection basket 19 has a drainage hole 19-1. The collection basket 19 is provided with a cleaning comb 20 for cleaning the cleaning brush 10.

[0016] The aforementioned drive assembly is used to drive the entire cleaning assembly 3 to operate. It includes a support shaft 15 rotatably mounted on a pair of mounting shells 4. The support shaft 15 is provided with multiple baffles 16 along the circumferential direction. The support shaft 15 is in transmission cooperation with the rotating shaft 6. Specifically, the two can be in transmission cooperation through a belt drive structure 17 or a sprocket drive structure.

[0017] To facilitate the smooth floating of the cleaning component 3 with the water level, the guide groove 2-1 is inclined upwards according to the water flow direction.

[0018] To ensure the floating effect of the cleaning component 3 in water, the material density of the mounting shell 4, filter plate 14 and moving plate 11 is less than that of water, and PP or PE materials can be used.

[0019] The specific working principle of this invention is as follows: When the device is in use, the water flows through the guide base 1 and then through the filter plate 14 of the cleaning component 3. After being filtered by the filter plate 14, the water impacts the baffle, causing the support shaft 15 to rotate. The support shaft 15 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the conveyor chain to rotate. The reciprocating thread on the rotating shaft 6 drives the reciprocating slider 12 to move back and forth. In turn, the moving plate 11 moves back and forth, causing the brush bristles 11-1 to clean the filter plate 14.

[0020] As the moving plate 11 moves back and forth, it pushes the floating objects to both sides, and then the cleaning brush 10 on the conveyor chain scrapes up the floating objects. Then the cleaning comb 20 on the collection basket 19 cleans the floating objects on the cleaning brush 10, so that the floating objects fall into the collection basket 19.

[0021] It should be noted that staff need to check the amount of contaminants in the collection basket 19 every once in a while. When the amount of contaminants in the collection basket 19 reaches a certain level, staff need to remove the collection basket 19 for cleaning and then put it back in its original position.

[0022] When the water level rises or falls, the slider 4-1 in the cleaning component 3 will move up and down along the guide groove 2-1 to adapt to different water levels.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
