Description

Technical Field

[0001] This invention relates to a tower-type photothermal heliostat cleaning mechanism, belonging to the technical field of tower-type photothermal heliostats. Background Technology

[0002] A tower-type solar thermal heliostat is an optical device that reflects sunlight in a fixed direction. It is responsible for precisely capturing sunlight and focusing it onto a receiver, serving as the starting point for the entire system's energy input. A heliostat is a precision mirror device equipped with a dual-axis (azimuth and elevation) tracking system. Its core tasks are: real-time sun tracking (using solar position algorithms and sensors to constantly align itself with the sun like a sunflower); and precise sunlight reflection (not simply reflecting incident sunlight back to the sun, but accurately reflecting it onto the receiver fixed at the top of the tower based on its position). Thousands upon thousands of heliostats form a vast heliostat field, like an "artificial sun," providing continuous, stable, and high-temperature thermal energy to the receiver.

[0003] The performance of heliostats directly determines the efficiency and economy of the entire solar thermal power generation system: Optical efficiency: Reflectivity, tracking accuracy, shading and shading losses, etc., jointly determine how much solar energy is ultimately delivered to the receiver; Concentration ratio: The design of the heliostat field determines the concentration ratio that the system can achieve, thus affecting the operating temperature of the receiver. The higher the temperature, the higher the efficiency of heat-to-electricity conversion is generally; Power plant output: A stable and uniform light spot is a prerequisite for the safe and efficient operation of the receiver, ensuring that the power plant can continuously output a stable amount of electricity.

[0004] Tower-type solar thermal heliostats are reflective devices used to focus sunlight. They are typically installed in open, arid locations to improve energy conversion efficiency, but this also increases dust accumulation, necessitating regular cleaning. Current cleaning methods involve using mobile cleaning vehicles to transport water for washing. However, the wastewater is directly discharged, increasing water consumption, especially in areas with severe drought and when there are many heliostats. Frequent trips by the cleaning vehicles further deplete resources and increase labor intensity, making cleaning of tower-type solar thermal heliostats inconvenient and affecting cleaning efficiency.

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] like Figure 1-10 As shown, the tower-type photothermal heliostat cleaning mechanism includes a heliostat assembly 100, on which a pentagonal lens 104 is mounted. A traveling assembly 400 is provided on one side of the heliostat assembly 100, and an adjustable rinsing assembly 200 is mounted on the traveling assembly 400. The rinsing assembly 200 has a built-in cleaning assembly 300. The rinsing assembly 200 includes a ring 201 and a cover 202. The edges of the ring 201 and the cover 202 are integrally formed. The ring 201 is fitted and connected to the edge of the lens 104. The bottom of the ring 201 is connected to a filter mechanism through a guide pipe 410. The filter mechanism is fixedly mounted on the traveling assembly 400.

[0039] A fixed rinsing mechanism is fixedly connected to the inner wall of the ring 201, and a rotating rinsing mechanism is also rotatably connected to the inner wall of the ring 201. The rotating rinsing mechanism is located on one side of the fixed rinsing mechanism, and both the rotating rinsing mechanism and the fixed rinsing mechanism are located at the top edge of the lens 104.

[0040] The cleaning assembly 300 includes a fixing post 301, which is installed in the middle of the cover 202. The bottom end of the fixing post 301 is rotatably connected to a plurality of rotating rods 304. Each rotating rod 304 has an arc-shaped bristle 305 fixedly connected to its bottom surface, and the bristle 305 is in contact with the surface of the lens 104.

[0041] The heliostat assembly 100 includes a column 101, a horizontal rotating seat 102 rotatably connected to the top of the column 101, a pitch rotating seat 103 rotatably connected to the horizontal rotating seat 102, and the pitch rotating seat 103 is fixedly connected to the lens 104 via a bracket. The lens 104 is composed of multiple individual triangular mirror bodies spliced ​​together, and a through hole 105 is formed in the middle of the splicing part of the lens 104.

[0042] In this technical solution, the horizontal rotation of the lens 104 is achieved by the horizontal rotating seat 102, while the vertical rotation of the lens 104 is driven by the pitch rotating seat 103, so as to achieve angle adjustment at any time to maximize the photothermal conversion efficiency. The heliostat is formed by splicing multiple lenses 104, and the splicing position is sealed. A through hole 105 is left in the middle for the installation of calibration cameras, etc. The through hole 105 is blocked during cleaning to ensure effective collection of wastewater.

[0043] The ferrule 201 has the same shape as the lens 104. The ferrule 201 has a raised edge that fits against the lens 104. The inner corners of the top of the ferrule 201 are fixedly connected to the fixed rinsing mechanism via an installation mechanism. The installation mechanism includes a fixing plate 203 and an installation plate 204. The fixing plate 203 has a U-shaped structure and is fixed to the inner wall of the ferrule 201. Installation plates 204 are fixedly connected to both side walls of the fixing plate 203. The installation plates 204 are fixedly connected to the fixed rinsing mechanism. The fixed rinsing mechanism includes a horizontal tube 205. The horizontal tube 205 is bent and fixedly connected to the inner wall of the ring 201. The horizontal tube 205 is fixedly connected to multiple mounting plates 204, and multiple evenly distributed first nozzles 206 are connected to the bottom of the horizontal tube 205. The first nozzles 206 are correspondingly arranged at the edge of the lens 104. A gap is formed between the first nozzles 206 and the lens 104 for the rotation of the rotating rod 304. The horizontal tube 205 is fixedly connected to the first hose 207. The first nozzles 206 are connected through the cover 202 and connected to the first hose 207.

[0044] In this technical solution, a ring 201 with the same shape as the lens 104 is provided, and the flange of the ring 201 is attached to the edge of the lens 104. At this time, the water source during cleaning can be collected inside the ring 201 and the cover 202, so that the wastewater after cleaning can be guided through the bottom of the ring 201, which facilitates the collection of wastewater and effectively avoids the waste of water resources. Compared with cleaning directly on the surface of the heliostat, it can significantly reduce water consumption without affecting the cleaning effect.

[0045] Furthermore, based on the shape of the heliostat, a horizontal tube 205 is installed in areas that the cleaning assembly 300 cannot reach. The horizontal tube 205 is fixed by the mounting plate 204 on the fixing plate 203 to improve the installation stability of the horizontal tube 205. Multiple first nozzles 206 are arranged at the horizontal tube 205 for rinsing the edge of the heliostat. The water generated by rinsing flows down the lens 104 and covers the cleaning assembly 300, so that the cleaning assembly 300 and the water source cooperate to achieve efficient sweeping. The water source is delivered to the horizontal tube 205 through the first hose 207 and sprayed out through the first nozzles 206.

[0046] Specifically, because the water source is collected and reused, the amount of water used during rinsing can be increased, and the rinsing degree will not be reduced due to the inability to use water resources, thus ensuring the rinsing effect on the edge of the heliostat.

[0047] The rotary flushing mechanism includes a fixed shaft 208, which is U-shaped and fixedly connected to the inner wall of the shroud 201. A bushing 209 is sleeved in the middle of the fixed shaft 208. A second nozzle 210 is welded and fixed to one side of the middle of the bushing 209. The second nozzle 210 communicates with multiple branch pipes 211, and the branch pipes 211 are fixedly connected to the side wall of the bushing 209. The second nozzle 210 is fixedly connected to a second hose 212, and the second hose 212 is connected to the cover 201. 2. Through connection, a fixed gear 213 is fixedly connected to the surface of the bushing 209, and the fixed gear 213 is located on one side of the second nozzle 210; an electric push rod 214 is fixedly installed on the top of the cover 202, the telescopic end of the electric push rod 214 is fixedly connected to the toothed plate 215, the toothed plate 215 is located between the fixed plate 203 and the fixed shaft 208, and the toothed plate 215 is meshed with the fixed gear 213, and the bushing 209 is rotatably connected to the fixed shaft 208.

[0048] In this technical solution, to further improve the cleaning effect on the edge of the lens 104, a rotating rinsing assembly 200 is provided to improve the cleaning and rinsing effect. During cleaning, the second hose 212 delivers water to the second nozzle 210 and branch pipe 211, and sprays water through the port for further rinsing. At the same time, the extension and retraction of the electric push rod 214 can drive the toothed plate 215 to move. When the toothed plate 215 moves, it drives the fixed gear 213 to rotate, so that the fixed gear 213 drives the bushing 209 to rotate around the fixed shaft 208. The bushing 209 drives the second nozzle 210 and branch pipe 211 on one side to rotate synchronously, so as to realize the angle adjustment of the second nozzle 210 to improve the rinsing effect. In conjunction with the fixed rinsing mechanism, the cleaning effect of multiple inner corner positions on the top of the lens 104 can be improved.

[0049] A connecting shaft 302 is fixedly installed at the bottom end of the fixed column 301. The bottom end of the connecting shaft 302 is fixedly connected to a disc-shaped sealing ring 303. The sealing ring 303 is fitted and sealed with the edge of the through hole 105. The connecting shaft 302 is rotatably connected to a plurality of evenly distributed rotating rods 304. The rotating rods 304 are set on the top surface of the sealing ring 303. Each rotating rod 304 has bristles 305 of different hardness at its bottom. The bristles 305 on the outer side are less hard than those on the inner side. A drive motor 307 is fixedly installed on the side wall at the bottom end of the fixed column 301. The output end of the drive motor 307 is fixedly connected to an output gear 308. A gear ring 306 is fixedly connected to the top surface of the rotating rod 304. The gear ring 306 is sleeved on the surface of the connecting shaft 302, and the output gear 308 meshes with the gear ring 306.

[0050] In this technical solution, the middle part of the cover 202 is connected to the connecting shaft 302 through the fixing post 301. The sealing ring 303 at the bottom of the connecting shaft 302 can fit with the through hole 105 to achieve sealing. When the walking component 400 drives the ring 201 to fit with the edge of the lens 104, the fixing post 301 can drive the sealing ring 303 to fit with the through hole 105, thereby preventing sewage from falling from the through hole 105, preventing pollution of the correction equipment, etc., and reducing water consumption.

[0051] Furthermore, the connecting shaft 302 can limit the rotation of the rotating rod 304 and enable the rotating rod 304 to rotate stably. When the output gear 308 is driven to rotate by the drive motor 307, the meshing of the output gear 308 and the gear ring 306 causes the rotating rod 304 to rotate synchronously, so that the rotating rod 304 drives the brush bristles 305 to contact the surface of the lens 104. When the water source flows to the surface of the lens 104 during cleaning, it contacts the brush bristles 305 and cleans them at the same time, improving the cleaning effect of the surface of the lens 104.

[0052] Specifically, each rotating rod 304 is equipped with arc-shaped bristles 305, which are adapted to the rotation direction of the rotating rod 304 to achieve water sweeping. At the same time, since the lens 104 has a large area, the bristles 305 at a distance move quickly when the rotating rod 304 rotates. Bristles 305 with different hardness can be selected to sweep the lens 104 at different positions. The bristles 305 on the inner side are harder, which can ensure the removal of stains even when rotating and sweeping at low speed, thus improving the cleaning effect.

[0053] The walking assembly 400 includes a walking trolley 401, which is positioned above a track 408 on the ground. A support base 402 is fixedly installed on the top of the walking trolley 401. A first hydraulic cylinder 403 is fixedly installed inside the support base 402. The telescopic end of the first hydraulic cylinder 403 is fixedly connected to a fixed base 404. A crossbeam 405 is fixedly installed inside the fixed base 404. One end of the crossbeam 405 is fixedly connected to a second hydraulic cylinder 406. The telescopic end of the second hydraulic cylinder 406 is fixedly connected to a telescopic beam 407. One end of the telescopic beam 407 is movably sleeved inside the crossbeam 405. One end is fixedly connected to the cover 202; a filter mechanism is fixedly installed on the side wall of the support base 402, the filter mechanism includes a filter box 409, the filter box 409 is fixedly connected to the side wall of the support base 402, the top of the filter box 409 is connected to the bottom of the ring 201 through a flexible guide pipe 410, a number of evenly distributed filter screens 411 are fixedly connected inside the filter box 409, the side wall of the filter box 409 is fixedly connected to a number of sewage pipes 412, the sewage pipes 412 are arranged above the filter screens 411, and the bottom of the filter box 409 is connected to the water tank on the traveling trolley 401 through a connecting pipe 413.

[0054] In this technical solution, the traveling trolley 401 can move on the pre-installed track 408. Before moving to the next heliostat assembly 100, the lens 104 is first straightened by the horizontal rotating seat 102 and the pitch rotating seat 103 so that it can be adapted to the traveling assembly 400. The extension and retraction of the first hydraulic cylinder 403 in the support seat 402 can drive the fixed seat 404 to rise and fall to adjust the height of the flushing assembly 200. After adjustment, the second hydraulic cylinder 406 is activated. The second hydraulic cylinder 406 pushes the telescopic beam 407 to move horizontally within the crossbeam 405, driving the ring 201 to move to the surface of the heliostat. The extension and retraction of the first hydraulic cylinder 403 and the second hydraulic cylinder 406 can ensure that the ring 201 can accurately and tightly fit the edge of the lens 104, thereby improving the efficiency of water resource recovery.

[0055] Specifically, when the lens 104 is rotated to a specified tilt angle to match the enclosure 201, and is rinsed by water sprayed from the first nozzle 206 and the second nozzle 210, the wastewater after rinsing flows to the bottom of the enclosure 201 and is guided by the guide pipe 410 to flow into the filter box 409. The filter screen 411 in the filter box 409 collects the impurities during cleaning and transports them to the water tank built into the traveling trolley 401 through the connecting pipe 413. Then, after adding cleaning agent, the water in the water tank is transported back to the enclosure 201 through the first hose 207 and the second hose 212 to achieve water circulation.

[0056] Furthermore, because the lens 104 is at an angle, the rinsing water will flow through the inner corner of the bottom of the lens 104, using clean water to continuously rinse the bottom of the lens 104 to ensure the cleaning effect.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
