Description

Technical Field

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

[0002] Different technical solutions should be adopted for cleaning solar photovoltaic panels in different regions and different application environments. Xinjiang Uygur Autonomous Region, Gansu Province, Qinghai Province, Inner Mongolia Autonomous Region and other regions in my country have rich solar energy resources, which are suitable for installing solar photovoltaic panels and building photovoltaic power stations. However, these regions are dry, rainless, and windy. A lot of dust, leaves and other coverings will accumulate on the surface of photovoltaic panels. The dust accumulation will reduce the transmittance of photovoltaic panels and affect the power generation efficiency of photovoltaic panels. Therefore, the use of effective dust cleaning methods and cleaning devices is a necessary operation and maintenance means to improve the efficiency of photovoltaic power generation and increase the income of photovoltaic power generation enterprises.

[0003] Among the existing cleaning technologies, wet water washing cleaning methods are difficult to implement in arid, rainless and water-deficient areas. The waterless cleaning method has two main disadvantages. The first is dust backflow. The invention patent "Cleaning Robot for Solar Power Plant" with publication number CN117730233A cleans the surface of solar panels by rotating the brush, but the rotation of the brush will cause the airflow to carry dust and scatter it, which can easily cause dust to fall back on the surface of the cleaned solar panel, making the cleaning effect worse; the second is that the cleaning device is not easy to move, and a single device cannot achieve efficient cleaning operations for multi-row and large-area photovoltaic panels.

[0004] Therefore, in order to meet the cleaning needs of solar photovoltaic panels in arid areas, it is urgent to develop a cleaning method and a cleaning device for solar photovoltaic panels. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a cleaning method and a cleaning device for a solar photovoltaic panel.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A method for cleaning a solar photovoltaic panel comprises the following steps: S1. Equipment connection: Move the cleaning equipment to the front of the solar panel through the movable device, and adjust the angle and position of the cleaning equipment to effectively adapt to the specifications of the solar panel; S2. Self-movement: The operation of the power component drives the belt assembly to operate, thereby causing the high-pressure fan assembly to reciprocate along the solar panel; when it moves into place, the axle fixed to the gear is pushed to rotate through the resistance component, and the gear is driven to rotate; when the gear rotates, it cooperates with the spur rack to make the equipment move in a directional manner; S3. High-pressure gas impact cleaning: The high-pressure fan assembly can make the high-pressure gas spray out in a directional manner to achieve blowing cleaning in two directions; when the high-pressure gas impacts the solar panel surface, the dust, leaves and other debris covering it are cleaned; at the same time, brush cleaning and exhaust components are also provided to improve the cleaning effect.

[0007] Compared with the prior art, in this cleaning method, the directional output of high-pressure gas can not only effectively clean the dust, leaves and other debris covering the solar panels, but also avoid dust backflow, thereby ensuring the cleaning quality of the cleaning area; secondly, the cleaning equipment can automatically move along the width and length of the solar panel, so that the entire solar panel can be comprehensively cleaned; in addition, through the cooperation of movable equipment and other components, the cleaning equipment can realize the cleaning of multiple rows of solar panels in different positions.

[0008] The present invention also proposes a solar photovoltaic panel cleaning device, which is applicable to the above-mentioned solar photovoltaic panel cleaning method, and is characterized in that: it comprises a solar panel, a movable body mechanism is provided on one side of the solar panel, a first mounting frame is installed on the movable body mechanism, a power mechanism is installed on the lower end of the first mounting frame, a high-pressure fan assembly and a cleaning brush are provided on the power mechanism, the cleaning brush is in conflict with the upper surface of the solar panel, the high-pressure fan assembly is arranged above the upper surface of the solar panel, the high-pressure fan assembly is slidably installed on the first mounting frame, a pushing mechanism is provided on one side of the first mounting frame, a gear and a spur rack are provided on the pushing mechanism, the spur rack is fixed to the upper end of the solar panel, and the gear and the spur rack are meshed with each other; A connecting pipe and a shunt pipe are respectively provided on both sides of the lower end of the high-pressure fan assembly, an exhaust pipe is fixed at the lower end of the connecting pipe, an L-shaped exhaust pipe is fixed on one side of the lower end of the high-pressure fan assembly, the L-shaped exhaust pipe and the shunt pipe are connected, a first oblique pipe fitting and a third oblique pipe fitting are respectively penetrated on both sides of the lower end of the L-shaped exhaust pipe, a second oblique pipe fitting is penetrated at the lower end of the exhaust pipe, the first oblique pipe fitting and the second oblique pipe fitting are arranged in parallel, the third oblique pipe fitting is vertically arranged on one side of the first oblique pipe fitting and the second oblique pipe fitting, an opening at the lower end of the third oblique pipe fitting is arranged on a side away from the first oblique pipe fitting and the second oblique pipe fitting, the first oblique pipe fitting, the second oblique pipe fitting and the third oblique pipe fitting are all located on the upper surface of the solar panel, and the air outlets of the second oblique pipe fitting and the first oblique pipe fitting are relatively arranged; A discharge mechanism is installed in the L-shaped exhaust duct.

[0009] Compared with the prior art, the high-pressure fan assembly in the present invention can automatically move along the solar panel by cooperating with the power component, and can also make the high-pressure gas flow in a directional manner to effectively clean the dust and other debris on the solar panel; in addition, the further cleaning effect of the brush component and the rapid collection of dust and other debris by the exhaust component can fully ensure the cleanliness of the solar panel surface, thereby better absorbing and converting solar energy.

[0010] Furthermore, the area surrounded by the L-shaped exhaust duct and the exhaust duct is the cleaning area where the high-pressure fan assembly is located. A part of the high-pressure gas generated by the high-pressure fan assembly is ejected through the second inclined pipe under the exhaust duct to blow away dust and other debris attached to the surface of the solar panel; the other part enters the third inclined pipe at the lower end of the L-shaped exhaust duct from the diverter pipe and is directly ejected from the third inclined pipe. Since the opening at the lower end of the third inclined pipe is arranged on the side away from the cleaning area, the high-pressure gas can be ejected to the periphery of the cleaning area to ensure that dust does not flow back into the cleaning area. At the same time, due to the rapid flow of the high-pressure gas, a negative pressure will be formed in the first inclined pipe, which can effectively suck the gas, dust, leaves, etc. in the cleaning area, and transport them to the L-shaped exhaust duct at the upper end of the first inclined pipe, so as to be discharged through the third inclined pipe.

[0011] Preferably, the movable body mechanism includes a movable bracket, the lower end of the first mounting bracket is rotatably connected to the upper end of the movable bracket, a motor seat is fixed on the first mounting bracket, a first hydraulic cylinder assembly is rotatably connected between the motor seat and the movable bracket, the motor seat is connected to a power mechanism, a support shaft assembly is provided on the first mounting bracket, the support shaft assembly includes a first support shaft and a second support shaft, the second support shaft is rotatably sleeved on the first mounting bracket, the first support shaft is slidably installed at the lower end of the motor seat, a second hydraulic cylinder assembly is fixed between the first support shaft and the first mounting bracket, and the gear is fixed at the lower end of the second support shaft.

[0012] Furthermore, during actual production and preparation, the motor seat is used to install the motor assembly and connect it to the corresponding power supply equipment and operating equipment. At the same time, the components of the high-pressure fan assembly used to connect to the power supply equipment and the control components can also be installed on the motor seat, which is convenient for the staff to operate. In addition, the angle of the first mounting frame can be effectively adjusted through the action of the first hydraulic cylinder assembly so that it can be the same as the angle of the solar panel, so that the corresponding components can work smoothly on the surface of the solar panel. At the same time, the distance between the support shaft assemblies can be controlled through the action of the second hydraulic cylinder assembly, that is, the distance between the first roller member and the second roller member can be controlled, so that the first roller member and the second roller member are respectively in contact with the upper and lower ends of the solar panel, which helps to move. And when the second support shaft rotates, it can make the gear rotate, and the gear cooperates with the spur rack to move the first mounting frame, which is convenient for gradually cleaning the solar panel.

[0013] Preferably, a roller assembly is jointly rotatably sleeved on the first support shaft and the second support shaft, the roller assembly includes a first roller member and a second roller member, the first support shaft and the first roller member are fixedly connected, the second support shaft and the second roller member are fixedly connected, the first roller member and the second roller member respectively abut against the upper and lower ends of the solar panel, and a resisting movable member is installed on the first mounting frame, the resisting movable member abuts against the solar panel, and the resisting movable member is located between the first support shaft and the second support shaft.

[0014] Furthermore, controlling the distance between the roller assemblies can effectively clamp the solar panel, while achieving triangular fixation through the action of the resisting moving member, thereby fully ensuring the stability of the position of the first mounting frame and facilitating the first mounting frame to move smoothly relative to the solar panel.

[0015] Preferably, the power mechanism includes a motor assembly and a second mounting frame, the motor assembly is mounted on a movable body mechanism, the second mounting frame is fixed on the first mounting frame, a transverse axis is fixed on the output shaft of the motor assembly, a reduction assembly is mounted on the second mounting frame, a double bevel gear linkage assembly is commonly connected to the transverse axis and the reduction assembly, a reciprocating mechanism is provided on the reduction assembly, a cleaning mechanism is connected to one end of the transverse axis away from the motor assembly, and the cleaning mechanism is located between the first oblique tube member and the second oblique tube member.

[0016] Furthermore, the motor assembly is connected to the power supply and control components. When the motor assembly is running, it can drive the transverse shaft to rotate, and the rotation of the transverse shaft can rotate the double-bevel gear linkage assembly, which adopts two mutually meshing bevel gear structures. A reduction assembly is installed on the second mounting frame, which can reduce the rotation speed of the linkage wheel connected to the reduction assembly and can accurately control the rotation speed of the linkage wheel. The linkage belt can rotate under the action of the linkage wheel, and the linkage wheel and the linkage belt are both toothed to ensure the stable transmission of power. Therefore, a single power source can provide power for the operation of the two groups of mechanisms, namely the reciprocating mechanism arranged on the reduction assembly and the cleaning mechanism connected to the end of the transverse shaft away from the motor assembly.

[0017] Preferably, the reciprocating mechanism includes a linkage wheel rotatably mounted on the deceleration assembly and the first mounting frame, a linkage belt is commonly sleeved between the two linkage wheels, a sleeve is installed on the linkage belt, a vertical rod is rotatably sleeved in the sleeve, a first push rod is slidably sleeved on the upper end of the vertical rod, and the first push rod is fixed to one side of the high-pressure fan assembly.

[0018] Furthermore, when the linkage wheel and the linkage belt are in operation, the sleeve on the linkage belt can be driven to circulate, and at the same time, the sleeve can push the vertical rod to move, and the vertical rod can push the high-pressure fan assembly to reciprocate along the first mounting frame, so as to facilitate the cleaning of the surface of the solar panel.

[0019] Preferably, the cleaning mechanism includes a support frame fixed on a first mounting frame, the cleaning brush is rotatably sleeved on the lower end of the support frame, the lower end of the first mounting frame is rotatably sleeved with a synchronous shaft, an opening is opened on the first mounting frame, a universal joint assembly is penetrated through the opening, the two ends of the universal joint assembly are respectively connected to the transverse shaft and the synchronous shaft, and a synchronous belt assembly is commonly connected between the synchronous shaft and the cleaning brush.

[0020] Furthermore, the universal joint assembly can enable the transverse axis to drive the synchronous axis to rotate, and the synchronous belt assembly connected to the synchronous axis and the cleaning brush can enable the cleaning brush to rotate, that is, after the high-pressure gas in the second inclined tube cleans the surface of the solar panel, the cleaning brush can clean the surface of the solar panel.

[0022] Further, the high-pressure blower assembly can reciprocate along the first mounting frame. When the high-pressure blower assembly moves to the top, the second push rod on one side of the exhaust pipe can push the push plate to make it conflict with the corresponding connection box, so that the push plate can drive the second support shaft to rotate, and the rotation of the second support shaft can rotate the gear fixed to it. The gear and the spur rack cooperate to enable the device as a whole to move relative to the solar panel, which is convenient for changing the cleaning area to achieve comprehensive cleaning of the solar panel. At the same time, when the second push rod rises, it will gradually move toward the second support shaft located at the upper end. At this time, the push plate conflicts with the corresponding connection box under the action of the spring member, and the second push rod can conflict with one of the push plates. As the second push rod continues to move upward, it can give one of the push plates a force to push, and the push plate will conflict with the connection box and make the second support shaft rotate, so that the gear can be driven to rotate. When the second support shaft rotates, it will cause another push plate to rotate in the direction of the second push rod, and the other push plate will conflict with the second push rod. Under the action of the spring member, the other push plate will stop moving after conflicting with the second push rod and will not affect the rotation of the second support shaft. When the second push rod moves to the right position, it will follow the high-pressure fan assembly to move toward the lower end of the solar panel and separate from the other push plate. At this time, the spring member connected to the other push plate can drive it to rotate, so that it can contact and fix with the corresponding connection box, so that when the second push rod moves upward again, it can contact with the push plate and realize the next push. In this cycle, directional movement is realized.

[0023] Preferably, the discharge mechanism includes an auger component rotatably sleeved in the L-shaped exhaust duct, the auger component is located at the upper end of the first inclined pipe component, one end of the auger component extends to the upper end of the third inclined pipe component, and a fan blade component is fixed on the auger component, and the fan blade component is located at the upper end of the third inclined pipe component.

[0024] Furthermore, when the high-pressure gas in the shunt pipe enters the L-shaped exhaust pipe, it will push the blade member on the auger member, causing the auger member to rotate. With the cooperation of the blade member and the auger member, directional transportation of dust and other debris can be achieved, that is, dust and other debris entering the L-shaped exhaust pipe from the first inclined pipe member can be transported to the upper end of the third inclined pipe member, so as to be easily output through the third inclined pipe member.

[0025] Preferably, a sliding frame is installed on one side of the high-pressure fan assembly, and the first mounting frame is arranged through the sliding frame.

[0026] Furthermore, it is ensured that the high-pressure fan assembly can move along the first mounting frame.

[0027] The beneficial effects of the present invention are: 1.

The surface of the solar panel cleaned by high-pressure gas can be cleaned again by a cleaning brush, so that dust and other debris on it can be sucked into the first inclined pipe through the negative pressure adsorption effect in the first inclined pipe, and directional transportation can be achieved through the cooperation of the fan blade and the auger to prevent dust from floating back; 4. The first hydraulic cylinder assembly and the second hydraulic cylinder assembly can realize that the mounting frame is located on the upper surface of the solar panel, and can ensure that it is in a position parallel to the upper surface of the solar panel, which helps to make the first roller member and the second roller member respectively contact the top and bottom of the solar panel, and realize triangular fixation by contacting the moving member against the upper surface of the solar panel, so as to ensure the stability of the position of the first mounting frame, so that the high-pressure fan assembly can move smoothly along the first mounting frame, and clean the moved area during the movement; 5. The cleaning device can be moved to the front of solar panels at different positions through the movable device, and the angle and position of the cleaning device can be adjusted to meet the needs of solar panels of different specifications.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In a solar photovoltaic power station, solar panels of the same specifications are usually connected in sequence to form a long row structure, and multiple rows are set up to effectively utilize the plant area. The power generation effect is affected by factors such as the geographical location, weather conditions, and the surface condition of the solar panels. Among them, the geographical location, weather conditions and other external conditions cannot be controlled manually, while the surface cleanliness of the solar panels can be effectively intervened manually to ensure the cleanliness of the surface, which helps to better receive solar radiation.

[0031] Example 1 Reference Figures 1 to 8 , this embodiment provides a cleaning method and cleaning device for a solar photovoltaic panel.

[0032] When the cleaning device of the present application is applied to a single solar panel 1, Figure 1As shown, the staff first moves the movable bracket 2 to the front end of the solar panel. Then the piston rod of the first hydraulic cylinder assembly 3 is controlled to retract, and the piston rod of the first hydraulic cylinder assembly 3 drives the first mounting frame 9 to deflect toward the solar panel 1 through the motor seat, so that the second roller member 3802 abuts against the upper end of the solar panel 1, and the gear 7 is meshed with the spur rack 8 at the upper end of the solar panel 1. Then, the staff controls the piston rod of the second hydraulic cylinder assembly 4 to push the first support shaft 3601 to move toward the direction of the solar panel 1, so that the first roller member 3801 on the first support shaft 3601 abuts against the lower end of the solar panel 1. As long as the width of the solar panel is within the length of the first mounting frame 9, the corresponding effective clamping operation can be achieved. At the same time, the cleaning brush 40 and the abutting movable member 6 abut against the surface of the solar panel 1, completing the connection between the cleaning device and the single solar panel 1.

[0033] The solar panel 1 may have different inclination angles when installed in different geographical environments. By adjusting the extension and contraction of the piston rod of the first hydraulic cylinder assembly 3, the first mounting frame can be parallel to the surface of the solar panel, so as to meet the needs of different inclination angles of the solar panel and improve the application range of the device.

[0034] In this embodiment, the high-pressure blower assembly 15 and the motor assembly 5 are started at the same time. The operation of the high-pressure blower assembly 15 can suck and compress the external gas into high-pressure gas. During the suction process, the dust in the gas can be effectively filtered to ensure the cleanliness of the subsequent output of high-pressure gas. The operation of the motor assembly 5 can drive the universal linkage assembly 31 and the second mounting frame 30 to rotate synchronously through the cooperation of the horizontal shaft 29 and the double-bevel gear linkage assembly 28. When the second mounting frame 30 rotates, the linkage wheel 26 and the linkage belt 25 can be rotated, and the speed reduction assembly 27 can control the rotation speed of the linkage wheel. Through the rotation of the linkage belt 25, the sleeve 11 can be driven to move, the sleeve 11 can push the vertical rod 12 to move, the vertical rod 12 can drive the first push rod 10 to move, and the vertical rod 12 can move relative to the first push rod 10, so as to adapt to the motion trajectory of the linkage belt 25 and realize the movement of the high-pressure blower assembly 15.

[0035] Among them, the sliding frame 14 fixed on one side of the high-pressure fan assembly 15 can only move along the first mounting frame 9, thereby ensuring that the high-pressure fan assembly 15 can also move along the first mounting frame 9 in the width direction of the upper surface of the solar panel 1.

[0036] At the same time, the transverse shaft 29 can rotate the synchronous shaft 39 through the universal linkage assembly 31, and drive the cleaning brush 40 to rotate through the synchronous belt assembly 33, so as to further clean the surface of the solar panel 1.

[0037] In this embodiment, the high-pressure gas generated by the high-pressure blower assembly 15 can enter the exhaust pipe 16 through the connecting pipe 17, and also enter the L-shaped exhaust pipe 22 through the shunt pipe 19. The high-pressure gas entering the L-shaped exhaust pipe 22 through the shunt pipe 19 will be directly ejected to the periphery of the cleaning area through the third oblique pipe 42 to ensure that dust does not flow back into the cleaning area. At the same time, the discharge of this high-pressure gas will cause the gas in the L-shaped exhaust pipe 22 to move toward the direction of the third oblique pipe 42. Since the first oblique pipe 13 and the L-shaped exhaust pipe 22 are connected, a negative pressure will also be formed in the first oblique pipe 13, which makes it easier for the first oblique pipe 13 to generate suction on the gas and dust, leaves and other debris in the area between the first oblique pipe 13 and the second oblique pipe 41, so that the dust-containing gas enters the L-shaped exhaust pipe 22 and is discharged through the third oblique pipe 42. The third oblique pipe is added with a corresponding purification filter bag to better prevent the dust from floating.

[0038] In this embodiment, the high-pressure gas entering the exhaust pipe 16 can be blown toward the surface of the solar panel 1 through the second inclined pipe 41, so that the dust and other debris on the surface of the solar panel 1 are blown up, and the dust-containing gas is further sucked through the first inclined pipe 13. At the same time, the cleaning brush 40 is located between the first inclined pipe 13 and the second inclined pipe 41, and contacts the surface of the solar panel 1, and can further clean and remove the dust and other debris on the surface of the solar panel 1, so that it is sucked into the L-shaped exhaust pipe 22 by the first inclined pipe 13.

[0039] Among them, when the high-pressure gas in the diversion pipe 19 enters the L-shaped exhaust duct 22, it will push the fan blade part 20 on the auger part 21, causing the auger part 21 to rotate. The rotation energy of the auger part 21 can transport dust and other debris that enter the L-shaped exhaust duct 22 from the first inclined pipe part 13 to the upper end of the third inclined pipe part 42, so that it can be discharged through the third inclined pipe part 42.

[0040] In this embodiment, the cyclic rotation of the linkage belt 25 can drive the high-pressure fan assembly 15 to move upward along the surface of the solar panel 1, and drive the second push rod 18 to move upward. When the high-pressure fan assembly 15 rises to the top of the solar panel, the second push rod 18 will contact the push plate 35 and make it squeeze the spring member 37 to rotate, so that the push plate 35 can contact the connection box 34, so as to drive the second support shaft 3602 to rotate, and make the second roller member 3802 and the gear 7 rotate, and under the action of the spur rack 8, it can drive the first mounting frame 9 to move along the length direction of the solar panel 1, so that the high-pressure fan assembly 15 can cover a new uncleaned area, and further make it descend to the bottom along the surface of the solar panel 1 and then rise to the top and then contact the push plate 35 again, so that the first mounting frame 9 and the high-pressure fan assembly 15 move again to cover a new uncleaned area. In this way, the high-pressure fan assembly 15 moves along the width and length of the solar panel 1 to complete the cleaning of the entire surface of the solar panel 1.

[0041] The position of the second push rod 18 can be controlled by adjusting the positioning bolt 24 and the connector 23 to ensure that the second push rod 18 can contact the push plate 35 and push the second support shaft 3602 to rotate through the connecting box 34.

[0042] At the same time, during production and preparation, according to the actual situation, a second push rod 18 can also be installed at the lower end of the other side of the high-pressure fan assembly 15. The two second push rods 18 are respectively on the diagonal of the high-pressure fan assembly 15 and are arranged in opposite directions. At the same time, a spur rack 8 is also installed at the lower end of the solar panel 1, and components such as a gear 7, a connecting box 34, a push plate 35 and a spring member 37 are also installed on the first roller member 3601, and the installation position and angle are adjusted according to the actual situation. In this way, when the high-pressure fan assembly 15 moves to the lower end of the solar panel 1, due to the action of the second push rod 18 at the lower end, it can also move along the length direction of the solar panel 1.

[0043] Example 2 In a solar photovoltaic power station, multiple solar panels 1 are often spliced ​​together to form a long row structure. Two adjacent solar panels 1 are set in abutment with each other, and the upper and lower ends are set flush. At this time, the cleaning method of the cleaning device is the same as that of Example 1. It is only necessary to ensure that the spur racks 8 on the upper ends of the multiple solar panels 1 can be accurately spliced ​​to form a complete rack structure so that the gear 7 can effectively mesh with the rack, and use this as a power to realize the movement of the device along a long row of multiple solar panels 1 to complete the cleaning work.

[0044] Example 3 For solar panels arranged in multiple rows, when the single row in Example 2 is cleaned, the staff controls the piston rod of the second hydraulic cylinder assembly 4 to retract, so that the first roller member 3801 is separated from the lower end of the solar panel 1, and at the same time, the telescopic rod of the first hydraulic cylinder assembly 3 is extended to drive the first mounting frame 9 to rotate in the vertical direction through the motor seat to complete the separation from the solar panel 1. After that, the staff controls the movable bracket 2 to move it to the front end of another long row of multiple solar panels 1, and after operating the first hydraulic cylinder assembly 3 and the second hydraulic cylinder assembly 4 again to complete the connection with the row of solar panels 1, the motor assembly 5 and the high-pressure fan assembly 15 are started to clean the row of multiple solar panels 1.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
