Description

Technical Field

[0001] The present invention relates to the field of photovoltaic panel cleaning, and in particular to a multifunctional cleaning machine for photovoltaic power generation. Background Art

[0002] During the use of photovoltaic panels, pollutants such as dust, bird droppings and leaves will accumulate on the photovoltaic panels, blocking the light received by the photovoltaic panels and reducing the amount of solar radiation received by the photovoltaic panels. In addition, surface dirt will scatter or reflect sunlight, reducing the efficiency of converting light energy into electrical energy, and the photovoltaic panels need to be cleaned.

[0003] Currently, photovoltaic panels are cleaned by photovoltaic panel cleaning robots or photovoltaic panel cleaning devices, and photovoltaic panel cleaning robots or photovoltaic panel cleaning devices mostly clean photovoltaic panels by rotating cleaning rollers. When using cleaning rollers to clean photovoltaic panels, the rotating cleaning rollers will swing the cleaned pollutants to the cleaned area, causing the cleaned area to be contaminated again, and the cleaned area needs to be cleaned again, which is more troublesome.

[0004] In order to increase the efficiency of photovoltaic panels in absorbing light energy, photovoltaic panels are generally placed at an angle, so that the photovoltaic panels need to bear a certain amount of wind load. In order to avoid the impact of excessive wind load on the photovoltaic panels, a thirty to fifty centimeter wind leakage channel is usually reserved between the photovoltaic panel arrays. When the wind leakage channel needs to be reserved, the number of photovoltaic panels is large. After completing the cleaning work of the current photovoltaic panel, the photovoltaic panel cleaning robot or photovoltaic panel cleaning device needs to be disassembled and reinstalled on the new photovoltaic panel that needs to be cleaned, and the work intensity of the staff is relatively high. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0031] Example 1

[0032] A multifunctional cleaning machine for photovoltaic power generation, such as Figures 1-8 and Figure 10 As shown, it includes a mounting frame 2, a track wheel 3 and a motorized roller 4; a drive motor is provided in the mounting frame 2; two track wheels 3 are mounted on the mounting frame 2, and the drive motor in the mounting frame 2 is used to provide power for the track wheels 3; a motorized roller 4 is mounted on the mounting frame 2;

[0033] It also includes a barrel 5, an arc-shaped plate 6, a pointed cone 7, an electric push rod 8 and a frustum 9; eight connecting plates 41 are provided on the electric roller 4; all the connecting plates 41 are fixedly connected to the barrel 5, the surface of the barrel 5 is provided with bristles, and the barrel 5 is provided with a number of through holes; all the connecting plates 41 are slidably connected to a arc-shaped plate 6, and all the arc-shaped plates 6 are provided with a number of springs, and the springs are located between the barrel 5 and the arc-shaped plate 6; all the arc-shaped plates 6 are fixedly connected to a number of pointed cones 7; the mounting frame 2 is fixedly connected to the electric push rod 8; the telescopic part of the electric push rod 8 is fixedly connected to the frustum 9; all the arc-shaped plates 6 are provided with arc surfaces, and the arc surfaces of all the arc-shaped plates 6 are located at one end close to the frustum 9, and the frustum 9 fits in with the arc surfaces of the arc-shaped plates 6.

[0034] All the pointed cones 7 pass through the corresponding through holes of the barrel 5. The length of the pointed cones 7 is shorter than the length of the bristles on the surface of the barrel 5. Increasing the overall length of the pointed cones 7 can better break the ice layer.

[0035] The arc surface of the arc plate 6 and the surface of the frustum 9 are smooth, which reduces wear during the contact process.

[0036] An air pump 101 is also included; the air pump 101 is installed on the mounting frame 2, and the air pump 101 is connected to the round table 9.

[0037] It also includes an air pipe 102 ; the air pipe 102 is installed on the mounting frame 2 , and the air pipe 102 is connected to the air pump 101 .

[0038] A connecting cloth 51 is provided at one end of the barrel 5 close to the truncated table 9 .

[0039] The length of the pointed cone 7 gradually shortens from front to back.

[0040] It should be noted that, in order to better achieve maintenance, a groove 11 is provided on the existing photovoltaic array 1 .

[0041] The working process of this multifunctional cleaning machine for photovoltaic power generation is as follows:

[0042] First, the staff places the photovoltaic power generation multifunctional cleaning machine on the photovoltaic group 1 that needs to be cleaned, so that the track wheel 3 is located in the groove 11;

[0043] When existing equipment uses a cleaning roller to clean photovoltaic panels, the rotating cleaning roller will throw the cleaned contaminants back to the cleaned area, causing the cleaned area to be contaminated again, requiring the cleaned area to be cleaned again, which is quite troublesome.

[0044] Start cleaning the photovoltaic group 1, start the driving motor in the mounting frame 2 to provide power for the track wheel 3, the track wheel 3 rotates to drive the present invention to move on the photovoltaic group 1, and at the same time start the electric roller 4, the electric roller 4 rotates counterclockwise when viewed from the front and the back, and the barrel 5, the arc plate 6 and the pointed cone 7 rotate accordingly. During the rotation, the bristles on the barrel 5 clean the surface of the photovoltaic group 1. While the bristles remove the dirt on the surface of the photovoltaic group 1, the impurities on the surface of the photovoltaic group 1 are cleaned simultaneously. In the process of cleaning the surface of the photovoltaic group 1, start the air pump 101 to transport air to the table 9 and the air pipe 102. The air transported to the table 9 flows into the barrel 5 and is ejected from the through hole thereon. The ejected air is blown between the photovoltaic group 1 and the mounting frame 2, and the air transported to the air pipe 102 is sprayed on the surface of the photovoltaic group 1. The air blows the dirt and impurities on the surface of the photovoltaic group 1 in the direction of movement of the track wheel 3 to prevent the cleaned dirt from returning to the cleaned area.

[0045] When cleaning photovoltaic panels in winter, after clearing the snow on the panels, there may still be ice on the panels. The ice blocks the sunlight and affects the power generation of the panels. Because the photovoltaic panels are in an inclined state, snow is easy to accumulate on the lower part of the panels. The ice layer on the lower part of the photovoltaic panels is thicker than the ice layer on the upper part of the photovoltaic panels. The thickness of the ice layer is between 0.1 and 1.5 centimeters.

[0046] When cleaning the photovoltaic group 1 in winter, after the present invention is placed on the photovoltaic group 1, the initial state of the pointed cone 7 is partially located outside the barrel 5, and the electric push rod 8 is controlled to push out a corresponding distance, allowing the table 9 to push the arc plate 6, so that the arc plate 6 slides on the connecting plate 41, and the spring on the arc plate 6 begins to shrink under the force, and the pointed cone 7 follows the movement, and the part of the pointed cone 7 located outside the barrel 5 gradually increases. After the distance between the pointed cone 7 and the surface of the photovoltaic group 1 is reduced to 0.5 centimeters, the electric push rod 8 stops pushing out, and then the electric roller 4 is started, and the corresponding parts follow the rotation. At this time, the present invention slowly moves in the direction of travel. During the movement, the rotating pointed cone 7 breaks the ice layer. The pointed cone 7 only breaks the ice layer on a large area, completing the pre-crushing treatment of the ice layer by the pointed cone 7, and does not directly act on the surface of the photovoltaic panel.

[0047] According to the above workflow, we can know that the present invention has the following effects:

[0048] When the present invention is used to clean the photovoltaic group 1, air is transported to the table 9 and the air pipe 102 by starting the air pump 101. The air transported to the table 9 flows into the barrel 5 and is ejected from the through hole thereon. The ejected air flows between the photovoltaic group 1 and the mounting frame 2. The air hits the surface of the photovoltaic group 1 and begins to diffuse around. During the air diffusion process, the air blows the bristles on the barrel 5, so that the bristles on the barrel 5 can achieve a certain degree of self-cleaning, which is beneficial for the bristles to maintain the cleaning effect on the photovoltaic group 1 for a long time. The air transported to the air pipe 102 is sprayed on the surface of the photovoltaic group 1. The air blows the dirt on the surface of the photovoltaic group 1 in the direction of movement of the track wheel 3 to prevent the cleaned dirt from returning to the cleaned area.

[0049] When the ice layer needs to be cleared, the electric push rod 8 is controlled to be pushed out a corresponding distance, so that the length of the pointed cone 7 outside the barrel 5 increases. After the distance between the pointed cone 7 and the surface of the photovoltaic group 1 is reduced to 0.5 cm, the electric push rod 8 stops pushing out, and then the electric roller 4 is started, and the corresponding parts follow the rotation. The rotating pointed cone 7 crushes the ice layer, completing the pre-crushing treatment of the ice layer by the pointed cone 7, thereby avoiding the ice layer affecting the efficiency of the photovoltaic group 1.

[0050] The additional technical effects of the present invention are as follows:

[0051] Among them, such as Figure 7 As shown, a connecting cloth 51 is added to the end of the barrel 5 close to the cone 9. When the air delivered to the cone 9 flows into the barrel 5, the end of the barrel 5 close to the cone 9 is blocked by the connecting cloth 51, so that the air delivered to the cone 9 can be better ejected from the through hole on the barrel 5.

[0052] Among them, such as Figure 10As shown, the length of the pointed cone 7 is set to gradually shorten from the front to the back. When the pointed cone 7 breaks the ice layer on the photovoltaic group 1, the pointed cone 7 at the bottom of the photovoltaic group 1 protrudes longer, but the pointed cone 7 at the bottom of the photovoltaic group 1 will not contact the photovoltaic group 1, so the ice layer at the bottom of the photovoltaic group 1 can be better broken.

[0053] Example 2

[0054] On the basis of Example 2, Figure 1 、 Figure 4 ,and Figure 9 As shown, it also includes a transfer component; two transfer components are installed on the mounting frame 2; the transfer component includes a gear 110, a mounting strip 111, a rack 112 and a rotating wheel 113; a motor is provided in the mounting frame 2; a gear 110 is installed in the mounting frame 2, and the motor in the mounting frame 2 provides power for the gear 110; a mounting strip 111 is slidably connected to the mounting frame 2; a rack 112 is fixed to the mounting strip 111, and the rack 112 is engaged with the gear 110; two rotating wheels 113 are rotatably connected to the mounting strip 111, and all the rotating wheels 113 are provided with a self-locking structure; all the rotating wheels 113 are provided with a number of empty slots 1131.

[0055] All the rotating wheels 113 are provided with a friction layer 1132 .

[0056] After the above embodiment completes the cleaning work of the photovoltaic group 1, the existing one needs to be disassembled and reinstalled on the new photovoltaic group 1 that needs to be cleaned, which increases the workload of the staff;

[0057] At this time, the present invention is located at the edge of the photovoltaic group 1. In the process of the rotating wheel 113 on the right moving to the next photovoltaic group 1, the track wheel 3 moves to above the air discharge channel. After the track wheel 3 is in a suspended state, the present invention stops moving, and the self-locking structure on the rotating wheel 113 is started to limit its rotation. Then the motor in the mounting frame 2 is started to drive the gear 110 to rotate. The gear 110 rotates clockwise when viewed from the front to the back. The gear 110 moves on the rack 112, and the mounting frame 2, the track wheel 3 and the parts connected thereto follow the movement. At this time, the track wheel 3 is still in a rotating state. After the track wheel 3 contacts the next photovoltaic group 1, the rotating track wheel 3 drives the other parts of the present invention to move on the next photovoltaic group 1.

[0058] During the movement of the present invention, the rotating wheel 113 may come into contact with an obstacle, which may lift the rotating wheel 113 and cause the entire present invention to tilt, thereby affecting the stability of the present invention.

[0059] By providing an empty groove 1131 on the rotating wheel 113, when the rotating wheel 113 contacts an obstacle, the obstacle will be guided into the empty groove 1131 and will not directly lift the rotating wheel 113, thereby reducing the degree to which the rotating wheel 113 is lifted, which is beneficial to the movement of the present invention.

[0060] According to the above workflow, we can know that the present invention has the following effects:

[0061] The installation frame 2, the track wheels 3 and the parts connected thereto are driven across the air leakage channel by the transfer assembly, and the staff do not need to dismantle the present invention and reinstall it on the next photovoltaic group 1, thereby reducing the staff's workload.

[0062] The additional technical effects of the present invention are as follows:

[0063] Among them, such as Figure 9 As shown, a friction layer 1132 is added to the rotating wheel 113 to increase the friction between the rotating wheel 113 and the photovoltaic array 1, so that the present invention can move on the photovoltaic array 1 more stably.

[0064] Example 3

[0065] On the basis of Example 1, Figure 5 As shown, the air outlet of the air pipe 102 is inclined to the right.

[0066] The additional technical effects of the present invention are as follows:

[0067] Among them, such as Figure 5 As shown, the air outlet of the air pipe 102 is set to be tilted to the right, so that the air blown out from the air pipe 102 is directed toward the direction of travel of the present invention, thereby improving the blowing effect of the air blown out from the air pipe 102 on the dirt on the surface of the photovoltaic group 1.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
