Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a power-off adsorption device and a cleaning robot. Background Technology

[0002] Solar photovoltaic (PV) technology, as a renewable and clean energy source, has become a vital force in today's energy transformation. However, behind the massive installed capacity lies a problem: the photoelectric energy conversion efficiency per photovoltaic panel in solar power plants falls far short of expectations. Therefore, the biggest challenge facing the solar energy industry in my country and worldwide is how to improve the photoelectric energy conversion efficiency of each photovoltaic panel. Dirt is one of the main factors contributing to the low photoelectric energy conversion efficiency of photovoltaic panels. This results in less than ideal power generation and significantly reduces the economic benefits of photovoltaic power generation. Excessive accumulation of this pollution can also damage photovoltaic modules. Therefore, it is essential to regularly clean the solar panels of photovoltaic power plants to ensure the economic benefits and power generation of photovoltaic power plants.

[0003] Currently, various cleaning robots have emerged for cleaning tilted solar photovoltaic panels. When powered on, the robot's built-in adsorption device can ensure that it can walk and clean on the photovoltaic panels. However, when the robot malfunctions and loses power, the tilted robot is prone to falling. To address this, we propose a power-off adsorption device and a cleaning robot. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to propose an inspection and cleaning system for photovoltaic panels, which facilitates the cleaning and maintenance of photovoltaic panels, ensures precise and stable docking between the damping chain mechanism and the clamping mechanism, reduces the probability of collision between the damping chain mechanism and the inspection and cleaning device, improves the reliability of the inspection and cleaning system for photovoltaic panels, and enhances work efficiency.

[0008] An electromagnet assembly is mounted on a mounting plate. The electromagnet assembly includes an electromagnet and a push rod inserted through the electromagnet. When the electromagnet is energized, the push rod moves upward. When the electromagnet is de-energized, the push rod moves downward under the action of an external force. The push rod moves synchronously with the suction cup. When the power is cut off, the electromagnet loses power, and the suction cup moves downward with the push rod, pressing and adhering to the working surface.

[0009] Furthermore, the power-off adsorption device also includes an on / off solenoid valve, which is mounted on the mounting plate. One air port of the on / off solenoid valve is connected to the inner cavity of the suction cup through an air pipe. When the on / off solenoid valve is de-energized, it evacuates the suction cup through the air pipe, increasing the adsorption force. When the on / off solenoid valve and the electromagnet are energized, the on / off solenoid valve blows air towards the suction cup to break the vacuum, and the electromagnet is energized, causing the push rod to move upward, which in turn moves the suction cup upward and releases the adsorption.

[0010] Furthermore, the adsorption assembly also includes a pressing column connected to the suction cup, and a sliding mechanism is installed between the pressing column and the mounting plate. The pressing column moves synchronously with the push rod to achieve synchronous up and down movement.

[0011] Furthermore, the pressing column is provided with a threaded section, and a connecting plate is fitted on the pressing column through a nut. The sliding mechanism includes a slider connected to the connecting plate and a guide rail mounted on the mounting plate for the slider to slide up and down.

[0012] Furthermore, the electromagnet assembly includes a mounting bracket for supporting the electromagnet, the mounting bracket being fixed to a mounting plate, both ends of the push rod extending through the mounting bracket to the outside of the mounting bracket, the lower end of the push rod being fixedly connected to a connecting plate via a U-shaped plate, and a spring-loaded assembly being installed between the upper end of the push rod and the mounting bracket.

[0013] Furthermore, the rebound assembly includes a spring surrounding the push rod, one end of which is connected to the upper end face of the mounting bracket and the other end of which is connected to the upper end of the push rod.

[0014] Furthermore, the mounting bracket is a rectangular frame with screw holes on its side wall. The rectangular frame is locked to the side wall of the mounting plate by bolts passing through the screw holes.

[0015] Furthermore, the mounting plate has guide holes on both sides of the guide rail, and the connecting plate is connected to guide columns that can move up and down within the guide holes.

[0016] Furthermore, the pressing column has a through hole that communicates with the suction cup, and one end of the air tube is connected to the through hole on the pressing column.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-4 This invention describes a power-off adsorption device and a cleaning robot according to embodiments of the present invention.

[0032] A cleaning robot, such as Figure 3 and Figure 4 As shown, the system includes a cleaning robot 100, on which several power-off adsorption devices 200 are installed. When the cleaning robot 100 loses power, the power-off adsorption devices 200 can be adsorbed onto the photovoltaic panel to prevent the cleaning robot 100 from falling.

[0033] In some examples, such as Figure 1As shown, the power-off adsorption device 200 includes a mounting plate 1, an adsorption component 2, and an electromagnet component 3. Both the adsorption component 2 and the electromagnet component 3 are mounted on the mounting plate 1. The adsorption component 2 has a suction cup 21, and the electromagnet component 3 is a push-pull electromagnet. The movable end of the push-pull electromagnet moves synchronously with the suction cup 21. When the power is off, the push-pull electromagnet loses power, and the suction cup 21 moves down with the movable end of the push-pull electromagnet, pressing and adsorbing onto the working surface. In this embodiment, the working surface is the photovoltaic panel surface.

[0034] As a preferred embodiment, such as Figure 1 As shown, the adsorption component 2 is movably mounted on the mounting plate 1. Specifically, the adsorption component 2 includes a suction cup 21 and a pressing column 22 connected to the suction cup 21. A threaded section is provided on the pressing column 22, and a connecting plate 23 is sleeved on the pressing column 22 through nuts. In detail, two nuts are threadedly connected to the threaded section of the pressing column 22. The two nuts are located on the upper and lower end faces of the connecting plate 23, which can adjust the position of the connecting plate 23 and has high adaptability. A sliding mechanism is installed between the connecting plate 23 and the mounting plate 1 to ensure that the suction cup 21 can slide up and down.

[0035] In some examples, the sliding mechanism includes a slider 24 connected to the connecting plate 23 and a guide rail 11 mounted on the mounting plate 1 for the slider 24 to slide up and down. In addition, guide holes are provided on both sides of the guide rail 11 on the mounting plate 1, and guide posts that can move up and down in the guide holes are connected to the connecting plate 23 to play a guiding role.

[0036] Electromagnet assembly 3 is mounted on mounting plate 1, specifically, refer to Figure 2 The electromagnet assembly 3 includes an electromagnet 31 and a mounting bracket 32 ​​for supporting the electromagnet 31. The mounting bracket 32 ​​is fixed on the mounting plate 1. A push rod 33 is inserted through the electromagnet 31. Both ends of the push rod 33 extend through the mounting bracket 32 ​​to the outside of the mounting bracket 32. The lower end of the push rod 33 is fixedly connected to the connecting plate 23 through a U-shaped plate 25. A spring-loaded assembly is installed between the upper end of the push rod 33 and the mounting bracket 32. When the electromagnet 31 is energized, the push rod 33 moves upward and compresses the spring-loaded assembly. When the electromagnet 31 is de-energized, the push rod 33 moves downward under the spring-loaded force of the spring-loaded assembly to increase the pressing force of the suction cup 21 to adsorb the photovoltaic panel downward.

[0037] In some examples, the rebound assembly includes a spring 34 surrounding the push rod 33, with one end of the spring 34 connected to the upper end face of the mounting bracket 32 ​​and the other end connected to the upper end of the push rod 33.

[0038] In some examples, the mounting bracket 32 ​​is a rectangular frame with screw holes on its side wall. The rectangular frame is locked to the side wall of the mounting plate 1 by bolts passing through the screw holes.

[0039] It should be noted that the push-pull electromagnet is obvious to those skilled in the art and belongs to the prior art. The specific structure of the electromagnet 31 includes a housing and a coil located inside the housing. The push rod 33 passes through the coil, and an iron core is sleeved on the part of the push rod 33 located inside the coil. When the coil is energized, the iron core drives the push rod 33 to move up or down. In this embodiment, when energized, the iron core drives the push rod 33 to move up and compress the spring 34.

[0040] To facilitate better adsorption and lifting of the suction cup 21, it is necessary to evacuate the suction cup 21 during descent and break the vacuum during ascent. Therefore, an on / off solenoid valve 4 is installed on the mounting plate 1, as per [reference needed]. Figure 1 and Figure 2 One air port of the on / off solenoid valve 4 is connected to the inner cavity of the suction cup 21 through the air pipe 41. Specifically, a through hole is opened on the pressing column 22 and the through hole is connected to the suction cup 21. One end of the air pipe 41 is connected to the through hole on the pressing column 22. When the on / off solenoid valve 4 is de-energized, the on / off solenoid valve 4 blows air into the suction cup 21 through the air pipe 41 to increase the adsorption force. When the on / off solenoid valve 4 and the electromagnet 31 are energized, the on / off solenoid valve 4 blows air into the suction cup 21 to break the vacuum. The electromagnet 31 is energized and the push rod 33 moves upward, which drives the suction cup 21 to move upward and release the adsorption.

[0041] As a preferred example in this case, for some rooftop photovoltaic systems, in order to facilitate the transport of cleaning robots up, this application adds an aircraft to the cleaning robot to carry it up, freeing up labor, eliminating the need for maintenance personnel to climb up and down, and reducing safety risks.

[0042] Other components and operations of the inspection and cleaning system 1 for photovoltaic panels according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
