Description

Technical Field

[0001] The present invention belongs to a solar panel cleaning device, and mainly relates to a cleaning device for dry-process solar panels. Background Art

[0002] Solar panels are prone to dust accumulation when exposed to the open air for a long time, which blocks the effective photoelectric conversion area, causes uneven radiative heat transfer on the panel surface, and thus affects the power generation efficiency of solar panels. Therefore, timely cleaning of the dust on the solar panel surface is extremely important for ensuring its photovoltaic conversion efficiency and the normal operation of the power plant.

[0003] The most effective way to clean solar panels is, of course, manual cleaning or cleaning by a human-controlled machine. As is well known, manual cleaning requires a large amount of manpower and has a low cleaning efficiency. In particular, it is very difficult to clean large-area solar panels; although machine cleaning can greatly improve the cleaning efficiency, it requires the use of special vehicles and requires a sufficient distance between solar panels. In addition, these two cleaning methods are extremely dependent on water resources, making it particularly difficult to clean solar panels efficiently in water-scarce areas (CN 222339339 U).

[0004] An ion blower is a cleaning method with a simple structure, low cost, low power consumption, no noise, and remarkable cleaning effect (CN108679000A), which can be used for dry cleaning of dust on the surface of solar panels. The biggest feature of ion blower cleaning is that it does not rely on water resources, and through the combination with a mobile device, mechanized and automated high-efficiency cleaning can be achieved. Summary of the Invention

[0005] The purpose of the present invention is to provide a dry-process solar panel cleaning device based on ion wind to solve the problems of existing solar panel cleaning devices that rely on water resources, have low cleaning efficiency, and consume a large amount of energy.

[0006] The present invention achieves the above object by the following technical means. The dry-type solar panel cleaning device based on ion wind includes: a solar panel, fixed guide rails, sliding guide rails, an ion fan cleaning device, baffles, a motor, etc. Its structure is as follows: Fixed guide rails are symmetrically arranged on both sides of the solar panel, and another two moving guide rails perpendicular to the fixed guide rails are mounted on the two fixed guide rails. The ion fan cleaning device is installed on the two moving guide rails and can slide along the guide rails. Baffles are respectively arranged at the ends of the two moving guide rails, and a connecting piece is arranged below the baffle. The connecting piece combines the fixed guide rail and the sliding guide rail together, and the baffle is in contact with the fixed guide rail. Fixed seats with grooves are respectively arranged at both ends of the ion fan cleaning device, and the two moving guide rails are installed in the grooves of the fixed seats. The center distance between the two fixed seats is equal to the center distance between the two moving guide rails. An air inlet is arranged at the upper part of the ion fan cleaning device; an air outlet is arranged at the lower part. Ion wind is generated by corona discharge between the high-voltage aluminum needle frame and the copper plate negative electrode in the ion fan cleaning device, and the ion fan cleaning device is used to move up, down, left and right on the track to sweep and clean the dust and dirt on the solar panel.

[0007] In the solar panel cleaning device, the gas between the high-voltage needle frame and the negative electrode plate collides and ionizes under the action of high voltage to generate charged particles. The charged particles are accelerated under the action of the electric field and cause momentum exchange by colliding with air molecules, which macroscopically manifests as fluid motion and is called "ion wind". The ion wind can blow away the sand grains and dust on the solar panel, thus realizing the dry cleaning of the solar panel.

[0008] The characteristics and advantages of the present invention are as follows: The new dry-type solar panel cleaning device based on ion wind realizes the efficient removal of sand grains and dust attached to the solar panel by generating ion wind through corona discharge technology. At the same time, the ion fan cleaning device realizes the all-round cleaning of the solar panel within the solar panel frame, has the characteristics of automation and high mechanization degree, greatly reduces the labor cost; the most crucial point is that it does not rely on water resources and solves the problem of cleaning solar panels in areas with harsh climate environments.

[0014] The following further elaborates on the structure of the present invention in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for any limitation to the present invention.

[0015] The dry-type solar panel cleaning device based on ion wind has the following structure: Fixed guide rails 2 are symmetrically arranged on both sides of the solar panel 1, and another two moving guide rails 3 perpendicular to the fixed guide rails are erected on the two fixed guide rails. The ion blower cleaning device 4 is installed on the two moving guide rails and can slide along the guide rails. Baffles 5 are respectively arranged at the ends of the two moving guide rails, and a connecting piece 6 (such as Figure 1 ) is arranged below the baffle. The connecting piece combines the fixed guide rail and the sliding guide rail together, and the baffle fits with the fixed guide rail. Fixed seats 7 with grooves are respectively arranged at both ends of the ion blower cleaning device, and the two moving guide rails are installed in the grooves of the fixed seats (such as Figure 5 ), and the center distance between the two fixed seats is equal to the center distance between the two moving guide rails. An air inlet 401 is arranged at the upper part of the ion blower cleaning device; an air outlet 402 is arranged at the lower part (such as Figure 2 , 3 , 4). Ion wind is generated through corona discharge between the high-voltage aluminum needle frame and the copper plate negative electrode in the ion blower cleaning device, and the ion blower cleaning device is used to move up, down, left, and right along the track to sweep and clean the dust and dirt on the solar panel.

[0016] The distance between the air outlet of the ion blower cleaning device and the surface of the solar panel is adjustable. A digital display panel 403, an ion wind speed adjustment knob 404, and a power switch 405 are arranged on the front of the ion blower cleaning device. The air inlet of the ion blower cleaning device is a three-row, multi-hole mesh structure; the air outlet is a narrow strip, single-row horizontal design, located in the center of the lower part of the ion blower, and the width of the air outlet is 20 mm; the length is 400 mm.

[0017] The ion blower cleaning device can move in the up and down directions along the moving guide rail through a motor according to a set program; the left and right movement of the ion blower cleaning device is realized by the movement of the moving guide rail on the fixed guide rail. The displacement in the up and down or left and right directions is driven by a motor to achieve comprehensive cleaning of the solar panel.

[0018] The installation directions of the fixed guide rail and the movable guide rail are determined according to the site conditions and requirements, that is: the two fixed guide rails can be arranged vertically or horizontally, and the two movable guide rails are perpendicular to the fixed guide rails. The length dimensions of the fixed guide rail and the sliding guide rail are designed based on the effective area where the ion fan cleaning device can clean within the length and width of the solar panel. Photoelectric protection devices are provided at both ends of the fixed guide rail and the sliding guide rail. When the ion fan cleaning device moves to the upper and lower edges of the solar panel surface, the motor will automatically stop.

[0019] The present invention does not rely on water resources and uses ion wind to remove sand grains and dust attached to the solar panel, performing dry cleaning on the solar panel. The sliding guide rail drive can be automatically lubricated without maintenance, and the two-dimensional movement of the cleaning device is driven by a drive motor. The baffle can effectively control the movement range of the cleaning device and prevent accidental detachment.

[0020] Inside the ion fan cleaning device body, the high-voltage needle holder uses an aluminum needle holder as the positive electrode, the negative electrode plate uses a copper plate, and the power supply is a high-voltage DC power supply. According to different cleaning degree requirements, the ion wind speed regulating knob is used to adjust the ion wind speed. The digital display panel can display the current ambient temperature, humidity, and the current working state of the cleaning device, facilitating the adjustment of the ion wind speed according to the actual situation.

[0021] As an example, the size of the solar panel is 1000mm in length × 1000mm in width. Accordingly, the length and width of the fixed guide rail and the movable guide rail are 1400mm and 1200mm respectively. The installation direction of the fixed guide rail is vertical, the movable guide rail is installed in the groove of the fixed seat, the center distance between the two fixed seats is 600mm, and the size of the ion fan cleaning device body is 500mm in length × 100mm in width × 200mm in height.

[0022] When in use, turn on the power switch, adjust the ion wind speed regulating knob to select an appropriate ion wind speed, such as 8m / s. The digital display panel can display the current ambient temperature, humidity, and the current working state of the cleaning device, facilitating adjustment according to the actual situation. At the same time, the ion fan cleaning device will move at a linear speed of 100mm / s along the movable guide rail in the up and down or left and right directions according to the set program under the drive of the motor, realizing the full-range cleaning of the solar panel. Photoelectric protection devices are provided at both ends of the fixed guide rail and the sliding guide rail, and baffles are respectively provided at the ends of the two movable guide rails. When the ion fan cleaning device moves to the upper and lower edges of the solar panel surface, the motor will automatically stop.

[0023] In summary, this device can achieve mechanized and automated high-efficiency dust removal and cleaning by combining with a mobile device without relying on water resources, improving the power generation efficiency of the solar panel and extending its service life.

[0024] Although embodiments of the present invention have been shown and described, various modifications and variations can be made to these embodiments by those of ordinary skill in the art without departing from the principles of the present invention, and all of them fall within the scope of the claims of the present invention.
