[0002] With technological advancements and cost reductions, photovoltaic power generation technology is gradually becoming an important part of the global energy structure transformation. The combination of new materials, integrated energy storage solutions, and smart grid technologies will further promote the popularization and application of photovoltaic power generation.

[0003] Photovoltaic power generation uses photovoltaic panels to convert sunlight into electricity. Especially in deserts, where there is ample sunlight and no light pollution, multiple photovoltaic panels are usually placed side by side in an array to improve the efficiency of sunlight utilization.

This invention utilizes the cooperative use of the mounting housing, the second moving component, and the mounting component. Under the action of the mounting component, the second moving component can have a tendency to move towards the first moving component, thereby allowing the first and second moving components to be stably clamped at the top and bottom of the photovoltaic array. Furthermore, the mounting component is linked with the locking component. When the mounting housing is removed from the photovoltaic array, the restriction of the mounting component on the locking component is released, allowing the locking component to be unlocked, thus enabling the brush roller to be directly disassembled and replaced.

[0022] Example 1 like Figures 1 to 7 As shown, this embodiment provides a sand-proof photovoltaic power generation device for desert power generation, including a photovoltaic array 1 for generating electricity through sunlight, an installation housing 2 disposed on the top of the photovoltaic array 1, a cleaning component 3 disposed inside the installation housing 2 for cleaning the surface of the photovoltaic array 1, an installation component 6, a first moving component 4 fixedly installed at one end of the installation housing 2, a second moving component 5 installed at the other end of the installation housing 2 via the installation component 6, the installation component 6, and a power module 7 fixedly installed on the top of the installation housing 2. The mounting housing 2 is slidably mounted on the top of the photovoltaic array 1 via the first movable component 4 and the second movable component 5. A control terminal is also fixedly mounted on the mounting housing 2. The power module 7 supplies power to the control terminal, the cleaning component 3, the first movable component 4 and the second movable component 5. The control terminal controls the operation of the cleaning component 3, the first movable component 4 and the second movable component 5 through wireless transmission technology.

[0023] Specifically, the photovoltaic array 1 is used to generate electricity using sunlight. The photovoltaic array 1 is formed by multiple photovoltaic panels installed side-by-side via a support frame. A mounting housing 2 is located on top of the photovoltaic array 1. A cleaning component 3 is located inside the mounting housing 2 and is used to clean the surface of the photovoltaic array 1, ensuring its cleanliness. A first moving component 4 is fixedly installed at one end of the mounting housing 2, and a second moving component 5 is installed at the other end of the mounting housing 2 via a mounting component 6. The mounting housing 2 is slidably installed on top of the photovoltaic array 1 via the first moving component 4 and the second moving component 5, and the bottom of the mounting housing 2 does not contact the photovoltaic array 1 to prevent movement of the mounting housing 2. The second moving component 5, under the action of the mounting component 6, tends to move towards the first moving component 4, thus ensuring the stability of the first moving component 4 and the second moving component 5 on the photovoltaic row 1. The power module 7 is fixedly installed on the top of the mounting housing 2, and a control terminal is also fixedly installed on the mounting housing 2. Thus, the power module 7 can provide power to the cleaning component 3, the first moving component 4 and the second moving component 5 through the control terminal. The control terminal has wireless transmission technology, so the staff can control its operation without being physically present on site. This is existing technology and will not be described in detail here.

[0024] Example 2 This embodiment is a further optimization based on Embodiment 1, specifically: The cleaning assembly 3 includes an end cap 31, a locking assembly 32, a mounting shaft 33, a brush roller 310, a transmission cap 34, and a first motor 35; The end cap 31 is fixedly installed on the end of the mounting housing 2 by the locking component 32.

One end of the outer wall of the mounting shaft 33 is slidably engaged with the transmission cap 34. That is, the transmission block that is engaged with the mounting shaft 33 is fixedly connected inside the transmission cap 34. The first motor 35 drives the mounting shaft 33 and the brush roller 310 to rotate through the transmission cap 34, so that the brush roller 310 cleans the surface of the photovoltaic array 1.

[0025] Cleaning component 3 also includes a limiting sleeve 36, a restraint cap 37, a fixing collar 38, and a positioning rod 39; One end of the limiting sleeve 36 is fixedly connected to the end cover 31, and the other end of the limiting sleeve 36 is slidably sleeved with the end of the mounting shaft 33. The binding cap 37 is slidably sleeved on the mounting shaft 33 between the limiting sleeve 36 and the brush roller 310. The end of the outer wall of the limiting sleeve 36 away from the end cover 31 and the end of the outer wall of the brush roller 310 close to the end cover 31 are respectively slidably sleeved at both ends of the binding cap 37. The fixing collar 38 is fixedly sleeved on the mounting shaft 33 between the transmission cap 34 and the brush roller 310. The positioning rod 39 is fixed on the fixing collar 38 near one end of the brush roller 310. The end of the brush roller 310 near the transmission cap 34 is provided with a positioning groove that slides and engages with the positioning rod 39.

[0026] Specifically, under the action of the restraint cap 37, the sealing between the brush roller 310 and the limiting sleeve 36 can be improved, and by removing the end cap 31 and separating the limiting sleeve 36 from the mounting shaft 33, the brush roller 310 can be directly slidably separated from the mounting shaft 33, thereby allowing the brush roller 310 to be disassembled and replaced. Under the action of the fixed collar 38 and the positioning rod 39, the brush roller 310 can rotate synchronously with the mounting shaft 33.

[0027] Example 3 This embodiment is a further optimization based on embodiment 2, specifically: Locking assembly 32 includes two locking units symmetrically arranged at end cap 31; Each locking unit includes a connecting plate 321, a fixing plate 322, a side plate 323, and a locking plate 324; The fixing plate 322 is fixedly connected to the inside of the mounting housing 2.

The side of the locking plate 324 away from the inner wall of the mounting housing 2 extends out of the locking hole of the fixing plate 322 and is fixedly connected to the side plate 323.

[0028] Specifically, one side of the connecting plate 321 is fixedly connected to the end cover 31, and the connecting plate 321 is slidably engaged inside the mounting housing 2. The opposite sides of the two connecting plates 321 are in contact with the inner wall of the mounting housing 2, and the opposite sides of the two connecting plates 321 are in contact with the inner wall of their respective fixed plates 322, thereby ensuring the stability of the horizontal position of the end cover 31. The side plate 323 is located on the side of the fixed plate 322 away from the connecting plate 321. The locking plate 324 is fixedly connected to the side plate 323 at the end away from the mounting housing 2. Locking holes are provided on one side of both the fixed plate 322 and the connecting plate 321. The locking plate 324 is slidably engaged with the inner cavity of the locking hole at the end away from the side plate 323. Thus, under the action of the locking plate 324, the connecting plate 321 is engaged inside the mounting housing 2, thereby ensuring the stability of the end cover 31 installation. The end cover 31 can be disassembled by pulling out the locking plate 324.

[0029] Example 4 This embodiment is a further optimization based on embodiment 3, specifically: Locking assembly 32 also includes locking lever 325, limiting block 326 and limiting lever 327; The locking rods 325 are two rods arranged side by side. One side of the two locking rods 325 is linked with the mounting component 6, and the other side of the two locking rods 325 is connected to the fixing plate 322 and the connecting plate 321 respectively through a sliding interlocking sleeve. The locking plate 324 has positioning holes that slide with the two locking rods 325 respectively. The axial direction of the locking rods 325 is orthogonal to the sliding direction of the locking plate 324.

The mounting roller 53 is fixedly installed at the end of the drive shaft extending out of the mounting sleeve 52. The second motor 54 drives the mounting roller 53 to rotate. Both the mounting sleeve 52 and the drive shaft have a certain length. When the mounting roller 53 is engaged on the photovoltaic array 1, the mounting housing 2 is in a floating state. The mounting roller 53 is engaged on the side of the photovoltaic array 1. The middle of the mounting roller 53 is provided with a recessed structure that can slide and engage on the side of the photovoltaic array 1.

[0032] Specifically, such as Figure 5 As shown, the second motor 54 is fixedly installed on the outside of the bearing housing 51. The output end of the second motor 54 is connected to the drive shaft for transmission. The bearing housing 51 is equipped with a chain and a sprocket. The second motor 54 drives the drive shaft and the mounting roller 53 to rotate through the chain and sprocket.

[0033] The second moving component 5 also includes a guide plate 55 and a slider 56; The top of the guide plate 55 is fixedly connected to the bearing housing 51. The guide plate 55 is disposed on the side of the mounting housing 2, and the guide plate 55 is linked with the mounting assembly 6. The slider 56 is fixedly connected to the side of the mounting housing 2. The guide plate 55 has symmetrical grooves on the side near the mounting housing 2. The outer wall of the slider 56 is slidably engaged with the inner cavity of the groove.

[0034] Specifically, under the action of the guide plate 55 and the slider 56, the bearing housing 51 formed by the second moving component 5 can be in a stable state and slide and engage with the mounting housing 2. The first moving component 4 and the second moving component 5 are made of the same structure, but the bearing housing 51 formed by the first moving component 4 is directly fixed to the mounting housing 2 by fasteners and fixing bolts.

[0035] Example 5 This embodiment is a further optimization based on embodiment 4, specifically: Mounting assembly 6 includes mounting plate 61, hinge 62, mounting hole 63, sliding hole 612, connecting rod 64, base plate 65, and spring 66; The hinge 62 is mounted on the side of the guide plate 55 away from the mounting housing 2, and the mounting plate 61 is connected to the hinge 62; Mounting hole 63 is formed on one side of guide plate 55, and one side of guide plate 55 fits against one side of inner wall of mounting hole 63; sliding hole 612 is formed on one side of mounting housing 2, and outer wall of mounting plate 61 slides and engages with inner cavity of sliding hole 612.

Spring 66 is slidably sleeved on connecting rod 64 located between mounting plate 61 and base plate 65.

[0036] Specifically, one end of the mounting plate 61 is rotatably connected to the guide plate 55 via a hinge 62, and the hinge 62 is mounted on the side of the guide plate 55 facing away from the mounting housing 2. A mounting hole 63 is formed on one side of the guide plate 55, and one side of the guide plate 55 is in contact with one side of the inner wall of the mounting hole 63. Figure 2 and Figure 4 As shown, when a force is applied to the two mounting plates 61 toward the first moving component 4, the two mounting plates 61 can be in a stable state to limit the guide plate 55. The sliding hole 612 is opened on one side of the mounting housing 2. The outer wall of the mounting plate 61 is slidably engaged with the inner cavity of the sliding hole 612.

The spring 66 is located between the mounting plate 61 and the bottom plate 65. The spring 66 can give the mounting plate 61 an elastic compressive force, so that the second moving component 5 has a tendency to move toward the first moving component 4. The elastic force of the spring 66 acting on the mounting plate 61 is sufficient to support the weight of the second moving component 5. The spring 66 can also give the bottom plate 65 a reverse force, thereby ensuring the stability of the locking rod 325 at the bottom of the bottom plate 65 engaging with the locking plate 324.

The outer wall of the restraining block 68 is slidably engaged with the mounting plate 61, and the bottom of the mounting plate 61 is provided with a restraining groove that matches the restraining block 68. The positioning plate 69 is fixedly connected to the inside of the mounting housing 2. Both the positioning plate 69 and the mounting plate 61 have a slot on one side that matches the connecting rod 64. The handle plate 610 is fixedly connected to the other end of the connecting rod 64. The handle plate 610 is located on the side of the positioning plate 69 away from the mounting plate 61. One end of the restraint rod 611 is fixedly connected to the handle plate 610, and the outer wall of the restraint rod 611 is slidably engaged with the positioning plate 69. The restraint rod 611 can improve the stability of the connection between the handle plate 610 and the positioning plate 69. When the housing 2 is removed from the photovoltaic array 1, the distance between the second moving component 5 and the first moving component 4 is at its shortest, and the spring 66 is at its maximum extension. Use the handle plate 610 to pull the connecting rod 64 to unlock the locking component 32. Then separate the restraining block 68 on the connecting collar 67 from the mounting plate 61, so that the connecting rod 64 is separated from the positioning plate 69 and the mounting plate 61, and the second moving component 5 can be disassembled for maintenance.

[0038] Specifically, the engagement of the restraint block 68 with the restraint groove ensures the stability of the connection between the connecting collar 67, the connecting rod 64, and the mounting plate 61.
