Description

Technical Field

[0001] This invention relates to the field of photovoltaic device technology, and in particular to photovoltaic devices with cleaning devices. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panel modules, controllers, and inverters. After a period of use, dust and sand particles will accumulate on the solar panels, affecting the light-gathering effect, so they need to be cleaned.

[0003] While existing devices can perform mobile rinsing, the connecting pipes used for rinsing are exposed to sunlight for extended periods, which can shorten their lifespan. Although existing devices can perform wiping and cleaning, the movement of the cleaning block with sand particles during wiping can cause wear and tear on the solar panels.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide photovoltaic devices with cleaning functions, in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a photovoltaic device with a cleaning mechanism. This addresses the issues that while existing devices can perform mobile rinsing, their connecting pipes are constantly exposed to sunlight, leading to a shortened lifespan. Additionally, while existing devices can perform wiping and cleaning, the movement of the cleaning block with sand particles during wiping causes wear and tear on the solar panels.

[0006] This invention provides a photovoltaic device with a cleaning mechanism, specifically including: a mounting frame; two support legs welded to the bottom end face of the mounting frame, both support legs being in contact with the ground, a photovoltaic panel fixed to the top end face of the mounting frame, and a first cleaning part mounted on the mounting frame; the first cleaning part consists of sliding protrusions, a first frame, a cleaning block, a first mounting block, a motor, and a threaded rod, two T-shaped sliding protrusions welded to the top end face of the mounting frame, a concave first frame sliding on the two sliding protrusions, a sponge-material cleaning block adhered to the top end face of the inner wall of the first frame, and the bottom end face of the cleaning block contacting the top end face of the photovoltaic panel.

[0007] Furthermore, two rectangular block-shaped first mounting blocks are welded to both the front and rear faces of the mounting frame. A threaded rod rotates together on the two first mounting blocks on the left side, and a threaded rod also rotates together on the two first mounting blocks on the right side. Both threaded rods are threadedly connected to the first frame body. A motor for driving the two threaded rods is fixed on each of the two first mounting blocks on the front side.

[0008] Furthermore, auxiliary protrusions are welded in a linear array on both the left and right sides of the top surface of the mounting bracket. The auxiliary protrusions are semi-cylindrical structures, and the inner sides of the left and right auxiliary protrusions contact the left and right end surfaces of the photovoltaic panel, respectively.

[0009] Furthermore, two spring rods are symmetrically welded to the bottom end face of the inner wall of the first frame. The protruding ends of the two spring rods are ground, and the lower end of the two spring rods is arc-shaped after grinding. The protruding ends of the two spring rods are in elastic contact with the top surface of the mounting frame. The two spring rods are aligned with the auxiliary protrusions on the left and right sides, respectively. When the two spring rods move forward with the first frame, the two spring rods and the auxiliary protrusions are in a continuous elastic engagement state.

[0010] Furthermore, the mounting frame is equipped with an auxiliary part, which consists of a base, a cleaning protrusion, and an auxiliary block. A concave base is welded to the top surface of the mounting frame, and the front end of the base contacts the rear end of the photovoltaic panel. A rectangular hole is opened on both the left and right sides of the base on the mounting frame.

[0011] Furthermore, the base is located in front of the cleaning block, and a triangular prism-shaped cleaning protrusion is welded to the top surface of the base. When the cleaning block moves forward, the bottom surface of the cleaning block makes elastic contact with the cleaning protrusion. An isosceles triangular block-shaped auxiliary block is welded to the recess of the base.

[0012] Furthermore, the mounting frame is equipped with a rinsing section, which consists of a second frame, a water tank, a water pump, a connecting pipe, a spray pipe, a first floating block, a connecting rod, a second floating block, and a stop block. Two F-shaped second frames are welded to the rear end face of the mounting frame, and a rectangular box-shaped water tank is welded to the top of the two second frames. A water pump is installed inside the water tank, and the water pump inlet pipe is located inside the water tank. A connecting pipe is connected to the water pump, and one end of the connecting pipe is connected to a spray pipe, which is fixed to the front end face of the first frame.

[0013] Furthermore, a rectangular block-shaped first floating block slides inside the water storage tank. The left and right sides of the first floating block are in contact with the left and right end faces of the inner wall of the water storage tank, respectively. Four connecting rods are fixed to the top surface of the first floating block. The upper ends of the two front connecting rods are fixed to a second floating block, and the upper ends of the two rear connecting rods are fixed to another second floating block. The outer sides of the two second floating blocks are in contact with the front and rear end faces of the inner wall of the water storage tank, respectively.

[0014] Furthermore, the mounting frame is equipped with a storage section, which consists of a second mounting block, a guide rod, a pull rod, and a helical spring. Two second mounting blocks are welded to the bottom end face of the mounting frame. Each second mounting block has a guide rod with a circular block welded to its rear end face. A cylindrical rod-shaped pull rod slides on the two guide rods. The rear end of each of the two helical springs is in elastic contact with the circular block on the rear side of the two guide rods, and the front end of each of the two helical springs is in elastic contact with the pull rod. The connecting pipe passes around the pull rod and connects to the nozzle.

[0015] Furthermore, a rectangular block structure is welded to the front end of the water tank, and the block is located above the connection between the connecting pipe and the spray pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this application, by setting up a storage section, when the connecting pipe moves with the first frame, it will pull the lever backward. When the first frame resets, the connecting pipe will be hidden under the photovoltaic panel under the resetting action of the lever, thus avoiding the connecting pipe being exposed to the sun for a long time, which would eventually shorten its lifespan. Compared with existing devices, this device can reduce maintenance costs.

[0018] This application, through the design of the auxiliary components, achieves the following: First, because the front end of the base contacts the rear end of the photovoltaic panel, the base can limit the front and rear positioning of the photovoltaic panel during installation, improving the installation efficiency. Second, when the first frame moves the cleaning block for cleaning, the cleaning block first contacts the cleaning protrusion, and the scraping action of the cleaning protrusion removes the dust and sand particles from the bottom of the cleaning block, ensuring the subsequent cleaning effect on the photovoltaic panel. Third, the scraped dust and sand particles fall onto the auxiliary block and, guided by the auxiliary block, fall from the left and right sides of the base, ensuring the cleaning effect.

[0019] This application, through the setting of the mounting rod and auxiliary protrusion, allows for continuous vibration when the first frame moves the cleaning block for cleaning. The continuous elastic engagement between the spring rod and the auxiliary protrusion generates continuous vibration, which shakes the sand particles off the photovoltaic panel, thus avoiding the cleaning block pushing the sand particles and causing wear on the photovoltaic panel. The structure is more reasonable.

[0020] This application, through the arrangement of a first floating block, a connecting rod, and a second floating block, allows rainwater to enter the water storage tank through the gap between the first and second floating blocks. The evaporation of water in the water storage tank can be reduced by the obstruction of the first and second floating blocks, resulting in a reasonable structure. Attached Figure Description

[0041] As attached Figure 1 To be continued Figure 9 As shown:

[0042] The present invention provides a photovoltaic device with a cleaning device, comprising: a mounting frame 1; two support legs 101 are welded to the bottom end face of the mounting frame 1, both support legs 101 are in contact with the ground, a photovoltaic panel 2 is fixed to the top end face of the mounting frame 1, and a first cleaning part 3 is installed on the mounting frame 1.

[0043] The first cleaning part 3 consists of a sliding protrusion 301, a first frame 302, a cleaning block 303, a first mounting block 304, a motor 305, and a threaded rod 306. Two T-shaped sliding protrusions 301 are welded to the top surface of the mounting frame 1. A concave first frame 302 slides on the two sliding protrusions 301. A sponge cleaning block 303 is attached to the top surface of the inner wall of the first frame 302. The bottom surface of the cleaning block 303 is in contact with the top surface of the photovoltaic panel 2.

[0044] The mounting frame 1 has two rectangular block-shaped first mounting blocks 304 welded to its front and rear faces. A threaded rod 306 rotates on both of the two first mounting blocks 304 on the left and the two first mounting blocks 304 on the right. Both threaded rods 306 are threadedly connected to the first frame 302. Each of the two front first mounting blocks 304 has a motor 305 fixed on it to drive the two threaded rods 306. When cleaning the photovoltaic panel 2, the two motors 305 are controlled to rotate, which drives the two threaded rods 306 to rotate. Driven by the two threaded rods 306, the first frame 302 moves. During the movement of the first frame 302, the cleaning block 303 can be moved to complete the cleaning of the photovoltaic panel 2.

[0045] Among them, auxiliary protrusions 102 are welded in a linear array on the left and right sides of the top surface of the mounting frame 1. The auxiliary protrusions 102 are semi-cylindrical structures. The inner sides of the left and right auxiliary protrusions 102 contact the left and right end surfaces of the photovoltaic panel 2, respectively. When installing the photovoltaic panel 2, the left and right auxiliary protrusions 102 can realize the left and right limit of the photovoltaic panel 2, thereby improving the installation efficiency of the photovoltaic panel 2.

[0046] Two spring rods 103 are symmetrically welded to the bottom surface of the inner wall of the first frame 302. The protruding ends of the two spring rods 103 are polished, and the lower end of the two spring rods 103 is arc-shaped. The protruding ends of the two spring rods 103 are in elastic contact with the top surface of the mounting frame 1. The two spring rods 103 are aligned with the auxiliary protrusions 102 on the left and right sides, respectively. When the two spring rods 103 move forward with the first frame 302, the two spring rods 103 and the auxiliary protrusions 102 are in a continuous elastic engagement state. When the first frame 302 moves the cleaning block 303 to clean, the continuous elastic engagement between the spring rods 103 and the auxiliary protrusions 102 can generate continuous vibration. The continuous vibration can shake off the sand particles on the photovoltaic panel 2, avoiding the cleaning block 303 from pushing the sand particles and causing wear to the photovoltaic panel 2.

[0047] The mounting frame 1 is equipped with an auxiliary part 4, which consists of a base 401, a cleaning protrusion 402, and an auxiliary block 403. A concave base 401 is welded to the top surface of the mounting frame 1, and the front end of the base 401 contacts the rear end of the photovoltaic panel 2. A rectangular hole is opened on both the left and right sides of the base 401 on the mounting frame 1. When installing the photovoltaic panel 2, the base 401 can be used to limit the front and rear positions of the photovoltaic panel 2, thereby improving the installation efficiency of the photovoltaic panel 2.

[0048] The base 401 is located in front of the cleaning block 303. A triangular prism-shaped cleaning protrusion 402 is welded to the top surface of the base 401. When the cleaning block 303 moves forward, the bottom surface of the cleaning block 303 elastically contacts the cleaning protrusion 402. An isosceles triangular block-shaped auxiliary block 403 is welded to the recess of the base 401. When the first frame 302 moves the cleaning block 303 to clean, the cleaning block 303 first contacts the cleaning protrusion 402. Under the scraping action of the cleaning protrusion 402, the dust and sand particles at the bottom of the cleaning block 303 can be scraped off, ensuring the cleaning effect of the cleaning block 303 on the photovoltaic panel 2. The scraped dust and sand particles will fall onto the auxiliary block 403 and fall from the left and right sides of the base 401 under the guidance of the auxiliary block 403. The sand particles falling from the left and right sides of the base 401 will fall to the ground through the rectangular hole.

[0049] The mounting frame 1 is equipped with a rinsing section 5, which consists of a second frame 501, a water tank 502, a water pump 503, a connecting pipe 504, a spray pipe 505, a first float block 506, a connecting rod 507, a second float block 508, and a stop block 509. Two F-shaped second frames 501 are welded to the rear end face of the mounting frame 1. A rectangular box-shaped water tank 502 is welded to the top of the two second frames 501. A water pump 503 is installed inside the water tank 502. The water inlet pipe of the water pump 503 is located inside the water tank 502. A connecting pipe 504 is connected to the water pump 503. One end of the connecting pipe 504 is connected to a spray pipe 505. The spray pipe 505 is fixed to the front end face of the first frame 302.

[0050] The water storage tank 502 contains a rectangular block-shaped first floating block 506 that slides inside. The left and right sides of the first floating block 506 are in contact with the left and right end faces of the inner wall of the water storage tank 502, respectively. Four connecting rods 507 are fixed to the top surface of the first floating block 506. The upper ends of the two front connecting rods 507 are fixed to a second floating block 508, and the upper ends of the two rear connecting rods 507 are fixed to another second floating block 508. The outer sides of the two second floating blocks 508 are in contact with the front and rear end faces of the inner wall of the water storage tank 502, respectively. During use, rainwater can enter the water storage tank 502 through the gap between the first floating block 506 and the second floating block 508. The evaporation of water in the water storage tank 502 can be reduced by the obstruction of the first floating block 506 and the second floating block 508.

[0051] The mounting frame 1 has a storage section 6, which consists of a second mounting block 601, a guide rod 602, a pull rod 603, and a coil spring 604. Two second mounting blocks 601 are welded to the bottom surface of the mounting frame 1. Each second mounting block 601 has a guide rod 602 with a circular block welded to its rear end face. A cylindrical rod-shaped pull rod 603 slides along the two guide rods 602. A coil spring 604 is sleeved on each of the two guide rods 602. The rear side of the two coil springs 604... One end of each of the two guide rods 602 is in elastic contact with the circular blocks on the rear side. The front end of each of the two helical springs 604 is in elastic contact with the pull rod 603. The connecting pipe 504 passes around the pull rod 603 and connects to the nozzle 505. During use, when the connecting pipe 504 moves with the first frame 302, it will pull the pull rod 603 backward. When the first frame 302 is reset, the connecting pipe 504 will be hidden under the photovoltaic panel 2 under the reset action of the pull rod 603, thus avoiding the connecting pipe 504 being exposed to the sun for a long time, which would eventually shorten its lifespan.

[0052] Among them, a rectangular block-shaped baffle 509 is welded to the front end of the water storage tank 502. The baffle 509 is located above the connection between the connecting pipe 504 and the nozzle 505. When the photovoltaic panel 2 is not cleaned, the baffle 509 can block the exposed part of the connecting pipe 504, thus ensuring the service life of the exposed part of the connecting pipe 504.

[0053] Working principle: When wiping and cleaning the photovoltaic panel 2, two motors 305 are controlled to rotate, driving two threaded rods 306 to rotate. Under the drive of the two threaded rods 306, the first frame 302 moves. During the movement of the first frame 302, it can move the cleaning block 303 to complete the cleaning of the photovoltaic panel 2. At the same time, when the first frame 302 moves the cleaning block 303 to clean, the cleaning block 303 first contacts the cleaning protrusion 402. Under the scraping action of the cleaning protrusion 402, the dust and sand particles at the bottom of the cleaning block 303 can be scraped off, ensuring the cleaning effect of the cleaning block 303 on the photovoltaic panel 2. The scraped dust and sand particles will fall onto the auxiliary block 403 and fall off from the left and right sides of the base 401 under the guidance of the auxiliary block 403. When the first frame 302 moves the cleaning block 303 for cleaning, continuous vibration is generated by the continuous elastic engagement of the spring rod 103 and the auxiliary protrusion 102. This continuous vibration can shake off the sand particles on the photovoltaic panel 2, preventing the cleaning block 303 from pushing the sand particles and causing wear to the photovoltaic panel 2. During rinsing and cleaning, the water pump 503 is started. The water pump 503 draws water from the water tank 502 and sprays it onto the photovoltaic panel 2 through the spray pipe 505. This achieves the rinsing of mud and sand on the photovoltaic panel 2. The rinsing can be achieved during the movement of the first frame 302. At the same time, when the connecting pipe 504 moves with the first frame 302, it will pull the pull rod 603 backward. When the first frame 302 resets, the connecting pipe 504 will be hidden under the photovoltaic panel 2 under the reset action of the pull rod 603.
