[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels (modules), controllers, and inverters. In the prior art, photovoltaic power generation panels are generally fixed in outdoor environments through brackets. The brackets for photovoltaic power generation panels are fixed metal frames. Through the brackets, the photovoltaic power generation panels can reach a certain inclination angle, so as to ensure that the photovoltaic power generation panels can receive direct sunlight as much as possible to improve the efficiency of photovoltaic power generation.

[0003] In the prior art, the brackets for installing photovoltaic panels are generally installed in a standard manner, and their functions are only to simply adjust the offset angle of the photovoltaic panels. However, after long-term use of the photovoltaic power generation panels, a lot of dust will adhere to their surfaces, and when there is more dust, it is easy to affect the power generation efficiency of the photovoltaic power generation panels. If manual cleaning is used, although the corresponding cleaning can be completed, generally the height at which the photovoltaic panels are set is relatively high, which will also pose corresponding safety hazards.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1, please refer to Figures 1-8 , a flexible adjustment bracket for photovoltaic power generation, including a bracket seat 1, and an installation base plate 101 for installing a photovoltaic panel 104 is installed on the bracket seat 1. Refer to Figure 1 It can be seen that a hydraulic rod for adjusting the angle of the installation base plate 101 is provided on the bracket seat 1. Therefore, after the user fixedly installs the bracket seat 1 at a specified position, the best angle of the installation base plate 101 can be adjusted through the hydraulic rod, so that after the photovoltaic panel 104 is installed, the photovoltaic panel 104 can work in real time. It should be noted that using the telescopic movement of the hydraulic rod to adjust the angle of the installation base plate 101 is a common existing technology for those skilled in the art, and users can adjust it according to actual situations and their own needs, and will not be elaborated here.

[0034] Refer to Figure 1It can be seen that a cleaning assembly 2 for cleaning the photovoltaic panel 104 is further provided on the mounting base plate 101. The cleaning assembly 2 is arranged on the top of the photovoltaic panel 104, and a connection is formed between the first connecting rod 204 in the cleaning assembly 2 arranged on the top of the photovoltaic panel 104 and the output end of the external hydraulic rod. The external hydraulic rod is arranged on the top of the mounting base plate 101. Therefore, when the user needs to clean the photovoltaic panel 104, only need to start the external hydraulic rod, and the external hydraulic rod will drive the first connecting rod 204 to move accordingly.

[0035] Refer to Figure 1 It can be seen that a first sliding groove 102 is opened at the inner wall of the mounting base plate 101. Refer to Figure 4 It can be seen that a third sliding groove 105 is opened at the inner wall of the first sliding groove 102, and the first connecting rod 204 is slidably arranged inside the third sliding groove 105. It should be noted that since the output end of the external hydraulic rod is sleeved on the first connecting rod 204 through a sleeve, through this setting, not only can the first connecting rod 204 follow the extension or retraction of the external hydraulic rod, and thus slide correspondingly inside the third sliding groove 105, but also when the first connecting rod 204 moves in the left-right direction subsequently, it will not affect the moving effect of the first connecting rod 204.

[0036] Refer to Figure 4 It can be seen that a number of limiting moving grooves 106 are further arranged inside the third sliding groove 105, and the limiting moving grooves 106 are equidistantly arranged. Therefore, when the first connecting rod 204 slides inside the third sliding groove 105, the first connecting rod 204 will be successively squeezed by a number of limiting moving grooves 106, so that the first connecting rod 204 makes Figure 4 a rightward movement. It should be noted that since the other end of the first connecting rod 204 is installed on the connecting rotating plate 203, and the cleaning roller 201 and the positioning base 202 are respectively installed on the connecting rotating plate 203, when the first connecting rod 204 moves, the entire cleaning assembly 2 will make Figure 4 the rightward movement in . That is to say, as the cleaning assembly 2 moves along the photovoltaic panel 104 and completes the cleaning of the dust and impurities on the surface of the photovoltaic panel 104, it will also make a reciprocating left-right movement on the photovoltaic panel 104.

[0037] It should be noted that the first connecting rod 204 slidably arranged inside the third sliding groove 105 is slidably arranged inside the limiting moving groove 106 through a ball. Through this setting, not only can the first connecting rod 204 be squeezed and restricted by the limiting moving groove 106 during the movement process, so as to make a reciprocating left-right movement, but also it prevents the first connecting rod 204 from being unable to reset after being squeezed, thus affecting the subsequent moving effect of the first connecting rod 204.

[0038] It should be noted that the connecting rotating plate 203 connecting the other ends of the cleaning roller 201 and the positioning base 202 is also slidably arranged inside the second chute 103 through the first connecting rod 204. Therefore, when the first connecting rod 204 slidably arranged inside the third chute 105 moves, the first connecting rod 204 arranged inside the second chute 103 will also move synchronously to avoid jamming.

[0039] It should be noted that corresponding cleaning bristles can also be arranged on the bottom surface of the cleaning roller 201. Through this arrangement, not only can the cleaning assembly 2 complete the cleaning effect on the surface of the photovoltaic panel 104 during the movement, but also during the movement, the cleaning assembly 2 can be moved left and right to further clean the corners of the photovoltaic panel 104, thereby effectively improving the cleaning effect on the photovoltaic panel 104.

[0040] At the same time, since the cleaning nozzle 219 in the cleaning assembly 2 will spray the photovoltaic panel 104 during the subsequent movement of the cleaning assembly 2, through the above-mentioned movement mode, the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104 can also be effectively changed, thereby further improving the cleaning effect of the cleaning nozzle 219 on the photovoltaic panel 104.

[0041] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that when the photovoltaic panel 104 is set outdoors, it is inevitable to adhere to sundries such as mud and water or bird droppings. If the mud and water or bird droppings and other sundries dry and harden, a certain degree of protrusion will be generated on the surface of the photovoltaic panel 104. At this time, if the cleaning roller 201 moves for cleaning, it will inevitably come into contact with these hard protrusions. If the cleaning roller 201 directly moves in contact, it is very likely to damage the surface of the photovoltaic panel 104. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1-8 On the one hand, refer to Figure 5It can be seen that a number of connecting through grooves 215 are formed on the bottom surface of the cleaning roller 201, and a cleaning nozzle 219 is arranged inside each connecting through groove 215. Therefore, when the cleaning roller 201 encounters dry and hard mud blocks or bird droppings during the moving cleaning process, due to the sliding arrangement on the positioning base 202, the cleaning roller 201 will move closer to the positioning base 202 at the moment of contacting the dry and hard mud blocks or bird droppings. This setting can effectively prevent the cleaning roller 201 from coming into close contact with the dry and hard mud blocks or bird droppings, thus avoiding the problem of possible damage to the photovoltaic panel 104. It should be noted that a connecting spring 210 is arranged between the cleaning roller 201 and the positioning base 202. Therefore, after the cleaning roller 201 moves closer to the center position of the cleaning roller 201, the reset elastic force of the connecting spring 210 can effectively perform the corresponding reset, so that in the subsequent movement, the cleaning roller 201 can still continue to clean the photovoltaic panel 104;

[0042] On the other hand, referring to Figure 5 It can be seen that a receiving cavity 208 is formed inside the cleaning roller 201. A positioning arc plate 209 and a water storage bladder 216 are arranged inside the receiving cavity 208. The positioning arc plate 209 and the water storage bladder 216 are fixedly connected. The top of the positioning arc plate 209 is fixedly connected to one end of the third connecting rod 211, and the other end of the third connecting rod 211 is fixedly connected to the positioning base 202. Through this setting, after the cleaning roller 201 moves closer to the positioning base 202, the water storage bladder 216 fixedly arranged inside the receiving cavity 208 will be squeezed by the cleaning roller 201. Since the water storage bladder 216 is communicated with the connecting water pipe 212, and the other end of the connecting water pipe 212 is communicated with the connecting base 213 connected to the cleaning nozzle 219, that is to say, when the water storage bladder 216 is squeezed by the cleaning roller 201, the water stored inside the water storage bladder 216 will be injected into the connecting base 213 through the connecting water pipe 212, and the water supply effect for the cleaning nozzle 219 will be completed, so that the surface of the photovoltaic panel 104 can be cleaned through the cleaning nozzle 219. Through this spraying, not only can the dry and hard mud blocks or bird droppings be softened, so that the cleaning roller 201 can effectively clean the softened mud blocks or bird droppings during the subsequent reset process, to avoid the problem that the cleaning roller 201 may come into close contact with the dry and hard mud blocks or bird droppings during the moving cleaning process, thus possibly causing damage to the photovoltaic panel 104, but also by spraying the photovoltaic panel 104 with the cleaning nozzle 219, the cleaning degree of the cleaning roller 201 on the photovoltaic panel 104 can be further improved, thereby effectively improving the cleaning efficiency of the photovoltaic panel 104.

[0043] It should be noted that a water storage cavity 220 is provided inside the connection base 213, and the connection water pipe 212 is communicated with the water storage cavity 220. Moreover, a rotational connection is provided between the connection base 213 and the connection water pipe 212. Therefore, even if the connection base 213 rotates, it will not affect the water supply effect of the connection water pipe 212 to the inside of the water storage cavity 220. Also, since the water storage cavity 220 is communicated with the cleaning nozzle 219 through a connection hose, that is to say, when the connection base 213 rotates, the water storage cavity 220 and the cleaning nozzle 219 are relatively stationary. Through this setting, the water supply inside the cleaning nozzle 219 can be effectively guaranteed.

[0044] Referring to Figure 8 As can be seen, a spiral groove 214 is provided inside each connection through groove 215, and the outer surface of the connection base 213 is slidably arranged inside the spiral groove 214 through a connection ball 217. Therefore, after the cleaning roller 201 moves closer to the positioning base 202, the connection base 213 originally arranged inside the connection through groove 215 will gradually extend out of the connection through groove 215. And through the limiting sliding of the connection base 213 and the spiral groove 214, the connection base 213 can also rotate correspondingly on the connection water pipe 212 during the extension process. That is to say, when the cleaning nozzle 219 sprays, it rotates while spraying. Therefore, through this setting, the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104 is further improved, and thus the cleaning efficiency of the photovoltaic panel 104 is improved.

[0045] A first bevel gear 223 is also fixedly connected to the bottom end of the connection water pipe 212, and a rotating connecting rod 221 is rotatably arranged inside the connection base 213. A second bevel gear 224 is fixedly installed on the rotating connecting rod 221, and the first bevel gear 223 and the second bevel gear 224 are meshed with each other. Therefore, after the connection base 213 rotates inside the spiral groove 214 through the connection ball 217, the connection base 213 also rotates around the connection water pipe 212 at this time. Therefore, the second bevel gear 224 will also synchronously rotate meshingly around the first bevel gear 223, thereby driving the rotating connecting rod 221 to perform a corresponding rotating effect.

[0046] Since one end of a connecting member 222 is also fixedly installed on the rotating connecting rod 221, and the other end of the connecting member 222 is installed on the cleaning nozzle 219, when the rotating connecting rod 221 rotates, it will also drive the cleaning nozzle 219 to rotate accordingly. By rotating the cleaning nozzle 219, the spraying angle of the cleaning nozzle 219 is also changed, thereby further improving the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104, and effectively improving the cleaning efficiency of the cleaning nozzle 219 on the photovoltaic panel 104.

[0047] Since the rotation of the connection base 213 is more than one week, that is to say, the rotation of the above-mentioned rotating link 221 is also more than one week. Therefore, if the cleaning nozzle 219 rotates according to this rotation, the cleaning nozzle 219 will be stuck. The teeth provided on the first bevel gear 223 are intermittently arranged. Therefore, when the second bevel gear 224 meshes and rotates around the first bevel gear 223, it can only be carried out when the teeth of the two are meshed with each other. When the second bevel gear 224 rotates to the part where the first bevel gear 223 is not provided with teeth, the second bevel gear 224 will not rotate. Also, since the rotating link 221 is rotationally arranged inside the connection base 213 through a torsion spring, it should be noted that one end of the torsion spring is fixedly connected to the connection base 213, and the other end of the torsion spring is fixedly connected to the rotating link 221. Therefore, after the second bevel gear 224 stops rotating, the rotating link 221 will be affected by the reset elastic force of the torsion spring, so as to rotate in the reverse direction, and then drive the cleaning nozzle 219 to rotate in the reverse direction. Through this setting, the situation that the cleaning nozzle 219 is stuck due to excessive rotation can be effectively avoided. Moreover, since the teeth on the first bevel gear 223 are intermittently arranged, the rotation and reset of the cleaning nozzle 219 will also be carried out reciprocally. By using this reciprocating swing, the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104 can be further improved, thereby effectively improving the cleaning efficiency of the photovoltaic panel 104.

[0048] It should be noted that referring to Figure 1 As can be seen, corresponding chutes are provided on the side wall of the mounting base plate 101, and a water supply pipe is slidably arranged inside the chute. The water supply pipe is communicated with the corresponding water storage bladder 216. Therefore, when the cleaning assembly 2 moves, the water supply pipe can also slide synchronously. This setting is to ensure that after the cleaning roller 201 releases the extrusion of the water storage bladder 216, a certain amount of water source will always be stored inside the water storage bladder 216, so that when encountering hard protrusions such as bird droppings next time, the water storage bladder 216 can still supply water to the cleaning nozzle 219 accordingly.

[0049] Meanwhile, when the cleaning component 2 disposed at the top end of the mounting base plate 101 moves to the bottom of the photovoltaic panel 104 under the extrusion of the hydraulic rod, the first cleaning of the photovoltaic panel 104 by the cleaning component 2 is completed at this time. At this time, the user can drive the cleaning component 2 disposed at the top end of the photovoltaic panel 104 to complete the corresponding reset by controlling the external hydraulic rod. Also, since the cleaning of the cleaning component 2 is mainly based on the contact extrusion between the limit movement groove 106 and the first connecting rod 204, the cleaning component 2 will come into contact with a number of limit movement grooves 106 again during the reset process. That is to say, the cleaning component 2 can still perform corresponding secondary cleaning on the photovoltaic panel 104 during the reset process. Therefore, through this setting, the cleaning effect of the cleaning component 2 on the photovoltaic panel 104 can be further improved.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0051] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
