Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cleaning equipment, and in particular to a photovoltaic panel cleaning robot and a use method thereof. Background Art

[0002] In photovoltaic power generation systems, photovoltaic panels are the core components for energy reception and conversion. They absorb sunlight and convert it into electrical energy to provide power support for various devices and power grids. In order to improve the power generation efficiency of photovoltaic panels, their surfaces must be kept in a good clean state. However, photovoltaic panels are usually installed outdoors and exposed to the natural environment for a long time, which will affect the light energy absorption efficiency of photovoltaic panels due to the accumulation of dust, bird droppings, leaves and other impurities.

[0003] Photovoltaic panels are generally installed in large areas in the form of arrays in photovoltaic power stations. In order to maximize the utilization efficiency of solar energy, photovoltaic panels are usually installed at a certain angle. This installation method improves the light absorption efficiency, but also causes the photovoltaic panels to bear greater wind load pressure. Therefore, in order to ensure the safety of the array structure, photovoltaic power stations usually reserve 30 to 50 cm of wind leakage channels between photovoltaic panels. There are already some photovoltaic panel cleaning robot products on the market. However, there are still some shortcomings in the existing devices: Uneven mixing of cleaning liquid: In the current cleaning device, the cleaning liquid and water in the water tank are usually statically mixed. During the cleaning process, it is easy to cause differences in cleaning effects due to uneven distribution of components, especially when the photovoltaic panel area is large. This phenomenon is more obvious. Low cleaning efficiency: Although the track design limits the range of motion of the cleaning component, in actual operation, the cleaning component is prone to shaking when moving on the inclined surface, thereby reducing the cleaning efficiency.

[0032] Example 1

[0033] like Figure 1-Figure 8 As shown,

[0034] A photovoltaic panel cleaning robot comprises a photovoltaic panel 101, a robot body 102 is arranged on the top of the photovoltaic panel 101, and a crawler 103 is arranged on the bottom of the robot body 102;

[0035] The top of the photovoltaic panel 101 is provided with a stirring device 2, which includes a water tank 201, the water tank 201 is fixedly connected to the top of the robot body 102, the top of the water tank 201 is fixedly connected to a support frame 202, the inner wall of the support frame 202 is provided with a motor 203, the output shaft of the motor 203 is fixedly connected to a rotating rod 204, the circumferential surface of the rotating rod 204 is fixedly connected to a fixed sleeve 205, the circumferential surface of the fixed sleeve 205 is rotatably connected to a rotating rod 206, the circumferential surface of the rotating rod 206 is fixedly connected to a stirring rod 207, and a rotating structure is provided on the side of the rotating rod 206. The force of the rotating rod driven by the motor to rotate cooperates with the components such as the support frame, the fixed sleeve and the stirring rod in the stirring device, so that the stirring rod can rotate while revolving, so as to achieve the effect of making the cleaning liquid and water in the water tank mixed more evenly, avoiding the uneven liquid components during the cleaning process, ensuring the consistency of the cleaning effect, improving the cleaning efficiency, reducing the cleaning time, and thus improving the working efficiency of the machine.

[0036] The rotating structure includes a round rod 208, which is fixedly connected to one end of the rotating rod 206. The circumferential surface of the round rod 208 is fixedly connected to a gear 209. A slide groove 212 is provided on the inner wall of the water tank 201. A block 213 is fixedly connected to the inner wall of the slide groove 212. The design of the block 213 allows the gear 209 to rotate. Through the revolution and rotation of the stirring rod 207, the cleaning liquid and water can be fully mixed, thereby avoiding uneven liquid components during the cleaning process and ensuring the consistency of the cleaning effect.

[0037] The side surface of the gear 209 meshes with the side surface of the block 213, the circumferential surface of the rotating rod 204 is fixedly connected to the fixed rod 210, and the circumferential surface of the fixed rod 210 is fixedly connected to the spiral blade 211. The design of the spiral blade 211 effectively eliminates the bubbles generated during the stirring process, avoids the interference of bubbles during the cleaning process, and ensures that the cleaning liquid can better contact the surface of the photovoltaic panel 101.

[0038] A cleaning device 3 is provided on the top of the photovoltaic panel 101, and the cleaning device 3 includes a belt 301, which is rotatably connected to the circumferential surface of the rotating rod 204, and the end of the belt 301 away from the rotating rod 204 is rotatably connected to the rotating shaft 302, and the circumferential surface of the rotating shaft 302 is rotatably connected to the connecting belt 304, and the end of the connecting belt 304 away from the rotating shaft 302 is rotatably connected to the rotating shaft 305, and the circumferential surface of the rotating shaft 305 is fixedly connected to the gear plate 306, and the bottom of the robot body 102 is rotatably connected to a long rod 308, and the circumferential surface of the long rod 308 is fixedly connected to a half gear 310, and the bottom of the long rod 308 is fixedly connected to a positioning plate 307, and the side of the positioning plate 307 is fixedly connected to a mounting plate 311, and a cleaning brush 312 is provided at the bottom of the mounting plate 311.

[0039] A fixed plate 303 is fixedly connected to the side of the robot body 102, and the rotating shaft 302 runs through the top of the fixed plate 303. The top of the rotating shaft 305 is rotatably connected to the bottom of the robot body 102. The design of the fixed plate 303 can make the rotating shaft 302 more stable, improve the stability of the equipment during operation, and ensure the consistency of the cleaning effect.

[0040] The side of the half gear 310 with the tooth block meshes with the side of the gear plate 306, and the circumferential surface of the long rod 308 is fixedly connected with a torsion spring 309. The end of the torsion spring 309 away from the long rod 308 is fixedly connected to the top of the positioning plate 307. The design of the torsion spring 309 ensures that the cleaning brush 312 can be reset when not working, thereby extending the service life of the cleaning brush 312 and reducing the wear on the photovoltaic panel 101.

[0041] In this embodiment, the present invention drives the rotating rod 204 to rotate through the motor 203, and then drives the fixed sleeve 205 to rotate through the rotating rod 204, and drives the rotating rod 206 to rotate through the fixed sleeve 205, and then drives the stirring rod 207 to rotate through the rotating rod 206, and drives the fixed rod 210 to rotate through the rotating rod 204, and then drives the spiral blade 211 to rotate through the fixed rod 210. The spiral blade 211 can eliminate bubbles generated during the stirring process, and drives the round rod 208 to rotate through the rotating rod 206, and then drives the gear 209 to rotate through the round rod 208. The gear 209 rotates to make the gear 209 meshing with the block 213 rotate, so that the stirring rod 207 can rotate while revolving, so as to achieve the effect of making the mixing more uniform, and make the cleaning liquid and water in the water tank 201 mixed more uniformly.

[0042] The belt 301 is rotated by rotating the rotating rod 204, and the rotating shaft 302 is rotated by the belt 301, and the connecting belt 304 is rotated by the rotating shaft 302, and the rotating shaft 305 is rotated by the connecting belt 304, and the gear plate 306 is rotated by the rotating shaft 305. When the side of the half gear 310 with the tooth block is meshed with the gear plate 306, the gear plate 306 drives the half gear 310 to rotate, and the half gear 310 drives the rotating shaft 305 to rotate. The long rod 308 rotates, and the positioning plate 307 is driven to rotate by the rotation of the long rod 308, and the mounting plate 311 is driven to rotate by the rotation of the positioning plate 307, and the cleaning brush 312 is driven to rotate by the rotation of the mounting plate 311. When the side of the half gear 310 with the tooth block is away from the side of the gear disk 306, the long rod 308 drives the positioning plate 307 to reset through the elastic force of the torsion spring 309, so that the cleaning brush 312 reciprocates left and right, thereby achieving the function of cleaning the photovoltaic panel 101 and increasing the cleaning effect.

[0043] Example 2

[0044] like Figures 1 to 8 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that, in this embodiment, a drying device 4 is arranged on the top of the photovoltaic panel 101, and the drying device 4 includes a nozzle 401, which is arranged on the top of the mounting plate 311, and a mounting block 402 is arranged on the top of the nozzle 401, and a slider 403 is slidably connected to the inner wall of the mounting block 402, and a positioning rod 404 is fixedly connected to the side of the slider 403, an air pump 405 is arranged on the top of the robot body 102, a connecting pipe 406 penetrates the side of the air pump 405, a water outlet pipe 407 penetrates the side of the water tank 201, and an extrusion rod 408 is fixedly connected to the side of the photovoltaic panel 101.

[0045] The end of the connecting pipe 406 away from the air pump 405 passes through the side of the mounting block 402, and the end of the water outlet pipe 407 away from the water tank 201 passes through the side of the mounting block 402. The water outlet pipe 407 allows the nozzle 401 to continuously spray water during the displacement process, thereby achieving efficient cleaning of the photovoltaic panel 101, ensuring uniform coverage of the cleaning liquid, and removing dirt and dust.

[0046] One end of the positioning rod 404 is set as a slope, and one end of the extrusion rod 408 is set as a slope. The extrusion rod 408 is located on the movement trajectory of the positioning rod 404. Through the linkage design of the positioning rod 404 and the extrusion rod 408, the robot can automatically control the water spraying and drying process, thereby improving the intelligent level of operation.

[0047] The number of cleaning brushes 312 is set to be several, and along the linear array at the bottom of the mounting plate 311, the initial state of the torsion spring 309 is a relaxed state, and the left and right reciprocating motion of the cleaning brush 312 can more comprehensively cover the surface of the photovoltaic panel 101, ensuring that dirt and dust are thoroughly removed, thereby enhancing the cleaning effect.

[0048] In this embodiment, the robot body 102 will be displaced during the cleaning process. The displacement of the robot body 102 drives the mounting block 402 and the nozzle 401 to be displaced, and then the displacement of the mounting block 402 drives the positioning rod 404 to be displaced. When the positioning rod 404 moves to the side of the extrusion rod 408, the extrusion rod 408 will squeeze the positioning rod 404 so that the positioning rod 404 drives the slider 403 to move. At this time, the slider 403 will block the water outlet of the water outlet pipe 407, and the air outlet of the connecting pipe 406 on the side of the air pump 405 is opened, so that the nozzle 401 sprays water to clean the photovoltaic panel 101 when the robot body 102 moves from left to right. After cleaning, when the robot body 102 moves in the reciprocating direction, the water outlet is closed, and the nozzle 401 sprays air to dry the residual water on the top of the photovoltaic panel 101, thereby increasing the cleaning effect.

[0049] The present invention achieves the effect of the stirring rod rotating while revolving through the motor driven rotating rod, and the stirring rod and other components in the stirring device cooperate with each other, so as to achieve the effect of the stirring rod rotating at the same time, thereby achieving the effect of making the cleaning liquid and water in the water tank mixed more evenly, avoiding the uneven liquid composition during the cleaning process, ensuring the consistency of the cleaning effect, improving the cleaning efficiency, reducing the cleaning time, and thus improving the working efficiency of the machine.

[0050] The present invention uses the force of the belt driven by the rotation of the rotating rod to cooperate with the rotating shaft, gear plate, half gear and other components in the cleaning device, so that the positioning plate is driven to rotate by the rotation of the long rod, and the mounting plate is driven to rotate by the rotation of the positioning plate, and the cleaning brush is driven to rotate by the rotation of the mounting plate, so that the cleaning brush can clean the photovoltaic panel by reciprocating left and right motion, thereby ensuring the thorough removal of dirt and dust and enhancing the cleaning effect.

[0051] In the present invention, the force used to drive the installation block and the nozzle to move by the displacement of the robot body cooperates with the connecting pipe, extrusion rod, air pump and other components in the drying device, so that the nozzle can spray water to clean the photovoltaic panel when the robot body moves from left to right. After cleaning, when the robot body moves in a reciprocating direction, the water outlet is closed, and the nozzle jets air to dry the residual water on the top of the photovoltaic panel, thereby achieving the effect of drying the photovoltaic panel, preventing water stains and dirt from attaching again, and maintaining a lasting cleaning effect.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
