Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, in particular to an automatic cleaning photovoltaic solar panel. Background Art

[0002] Photovoltaic solar panels are devices that can convert solar energy into electrical energy. They are also called solar panels or photovoltaic panels. Their working principle is based on the photovoltaic effect, that is, when sunlight shines on solar cells made of semiconductor materials (such as silicon, selenium and copper indium gallium sulfide), the energy of sunlight is absorbed, resulting in the separation of electron-hole pairs inside the battery to form an electric current. In actual use, photovoltaic solar panels need to be exposed to the outside world for a long time, so that a large amount of dust will be absorbed on their surface. People need to use a brush to clean the dust on the surface of the photovoltaic panels. However, after the brush cleans the photovoltaic solar panel, a large amount of dust will also adhere to its inside, resulting in reduced subsequent cleaning effect.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN217646992U proposes an automatic cleaning device for photovoltaic solar panels. The device makes the brush roller contact with the paddle plate under the action of an electric telescopic rod, and the dust attached to the bristles on the surface of the brush roller falls off through the mutual collision between the paddle plate and the bristles on the surface of the brush roller, thereby cleaning the dust on the surface of the brush roller.

[0004] However, although the above-mentioned automatic cleaning device of the photovoltaic solar panel can make the paddle contact with the bristles on the surface of the brush roller through the electric telescopic rod, so that the dust attached to the bristles on the surface of the brush roller falls off, the brush roller of the automatic cleaning device of the photovoltaic solar panel will absorb a large amount of water after contacting with water, and cannot quickly shake off the water on the brush roller, so that the water on the brush roller will accumulate inside it, causing the brush roller to easily become moldy or even damaged. Therefore, the utility model provides an automatic cleaning photovoltaic solar panel to meet the demand. Utility Model Content

DETAILED DESCRIPTION

[0033] like Figures 1 to 7 As shown, an embodiment of the utility model provides an automatic cleaning photovoltaic solar panel, including a frame 1, a photovoltaic panel arranged on the frame 1, and an installation box 5 slidably arranged on the frame 1, a cleaning roller 16 that can fit with the photovoltaic panel 2 is rotatably connected to the installation box 5 through a rotating shaft 17, the rotating shaft 17 is driven by a second motor 13, a fixing box 12 is provided on the top of the installation box 5, a through opening is penetrated through the bottom of the installation box 5 facing the cleaning roller 16, a suction and blowing dual-purpose fan 27 is provided in the fixing box 12, an exhaust passage 19 that connects the outlet of the suction and blowing dual-purpose fan 27 with the through opening is provided between the inner wall and the outer wall of the installation box 5, a connecting box 20 is connected between the suction and blowing dual-purpose fan 27 and the exhaust passage 19, and a control mechanism 6 for controlling the suction and blowing dual-purpose fan 27 and the second motor 13 is provided on the top of the fixing box 12.

[0034] Specifically, the rotating shaft 17 is driven to rotate by the second motor 13, and the rotating shaft 17 drives the cleaning roller 16 to rotate, and then the installation box 5 slides along the length direction of the frame 1 to clean the surface of the photovoltaic panel 2. At the same time, the suction and blowing dual-purpose fan 27 is started by the control mechanism 6, so that the suction and blowing dual-purpose fan 27 generates an inward suction force, and cooperates with the exhaust duct 19 to suck the dust cleaned by the cleaning roller 16 along the opening, thereby realizing the collection of dust. Secondly, when the cleaning roller 16 needs to be air-dried, the suction and blowing dual-purpose fan 27 is controlled by the control mechanism 6 to generate an outward blowing wind force, so that the cleaning roller 16 is air-dried by strong wind, which speeds up the air-drying efficiency of the cleaning roller 16 and avoids the phenomenon that water on the cleaning roller 16 accumulates inside it to cause mold or even damage. The problem that the brush roller of the existing photovoltaic solar panel absorbs a large amount of water after contacting with water and cannot quickly dry the water on the brush roller, thereby causing most of the water to accumulate inside the brush roller, causing mold or even damage inside it, is solved.

[0035] It should be noted that the wind blown out by the suction and blowing dual-purpose fan 27 is hot air. When the suction and blowing dual-purpose fan 27 discharges hot air to dry the cleaning roller 16, the second motor 13 will not drive the cleaning roller 16 to rotate, and the through hole is arranged at an angle at the bottom of the mounting box 5, and the through hole faces the bottom of the cleaning roller 16, which makes the suction and blowing dual-purpose fan 27 drive the cleaning roller 16 to rotate when blowing, thereby realizing automatic drying of the cleaning roller 16; secondly, the connecting box 20 can ensure that the suction and blowing dual-purpose fan 27 is connected with the exhaust channel 19; further, the suction and blowing dual-purpose fan 27 is a fan device that can suck and blow air at the same time, it usually has two air inlets and one air outlet, and generates airflow through the internal rotating impeller, thereby realizing the functions of suction and blowing.

[0036] like Figure 5 As shown, in this embodiment, a collecting box 23 which is connected to a collecting port of a suction and blowing fan 27 is fixedly connected inside the fixing box 12 .

[0037] like Figure 8 As shown, in the present embodiment, a brush 26 and a sponge block 8 which fit the cleaning surface of the photovoltaic panel 2 are fixedly connected to the outer wall of the cleaning roller 16 at intervals. The brush 26 and the sponge block 8 are arranged around the outer wall of the cleaning roller 16 in a spiral structure. The length of the brush 26 is greater than the thickness of the sponge block 8. The sponge block 8 is evenly provided with protrusions 4 which can fit the cleaning surface of the photovoltaic panel 2. Specifically, the stains on the surface of the photovoltaic panel 2 can be brushed off by the brush 26, and at the same time, they can be wiped off by the sponge block 8 and the protrusions 4, thereby improving the cleaning effect of the photovoltaic panel 2.

[0038] like Figure 2 , Figure 4 and Figure 5 As shown, in the present embodiment, a water pump 22 and a water tank 21 connected to the water inlet of the water pump 22 are fixedly connected in the fixing box 12, a water outlet of the water pump 22 is connected to a water pipe 14, a drain cylinder 15 is fixedly connected to the relative opening of the installation box 5, the drain cylinder 15 is connected to the water pipe 14, a plurality of drain holes 25 are penetrated through the drain cylinder 15 facing the cleaning roller 16, the water pump 22 is connected to the control mechanism 6 by signal, specifically, the water pump 22 is started by the control mechanism 6, the water in the water tank 21 is discharged to the drain cylinder 15 through the water pipe 14, and then discharged to the surface of the cleaning roller 16 through the drain holes 25, thereby achieving a cleaning effect on the photovoltaic panel 2. It should be noted that the suction and blowing dual-purpose fan 27 will not be started when the water pump 22 is in use, and the suction and blowing dual-purpose fan 27 can only be started and used when the water pump 22 stops. The setting of the water pump 22 is intended to improve the cleaning effect on the photovoltaic panel 2.

[0039] like Figure 5 and Figure 7As shown, in the present embodiment, the top of the water tank 21 extends to the outside of the fixed box 12 and is penetrated by an opening 29, and three baffles 7 are fixedly connected to the opening 29 of the water tank 21 along its circumference direction, and a sewage outlet 28 is formed between the three baffles 7, and a filter plate 24 connected to the sewage outlet 28 is arranged downwardly inclined between the three baffles 7. Specifically, the opening 29 can facilitate the collection of rainwater by the water tank 21, and at the same time, the filter plate 24 can filter external impurities and discharge them along the sewage outlet 28, thereby realizing automatic replenishment of the water source in the water tank 21.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, two sliders 11 are fixedly connected to the two mounting boxes 5, a slide groove 10 for the sliders 11 to slide is provided on the frame 1, and a driving assembly 9 for driving the sliders 11 to slide along the slide groove 10 is provided on the frame 1. The driving assembly 9 includes a first motor 91, two threaded rods 93 and a belt transmission mechanism 92. The two threaded rods 93 are rotatably connected in the slide groove 10, and the two threaded rods 93 respectively penetrate and are threadedly connected to the two sliders 11. The two threaded rods 93 are connected by a belt transmission mechanism 92, and the threaded rods 93 are driven by the first motor 91, and the first motor 91 is fixed on On the frame 1, an infrared sensor 3 connected to the signal of the control mechanism 6 is fixedly connected to the frame 1. Specifically, one of the threaded rods 93 is driven to rotate by the first motor 91, so that the other threaded rod 93 is rotated under the linkage of the belt transmission mechanism 92. The rotation of the threaded rod 93 drives the slider 11 to slide along the slide groove 10, so that the cleaning roller 16 cleans the photovoltaic panel 2. When the cleaning roller 16 moves to the infrared sensor 3, the first motor 91 reverses, thereby driving the cleaning roller 16 to reset; the first motor 91 and the second motor 13 can be three-phase motors, reduction motors, etc.

[0041] Working principle:

[0042] The first motor 91 drives one of the threaded rods 93 to rotate, thereby realizing the rotation of the other threaded rod 93 under the linkage of the belt transmission mechanism 92. The rotation of the threaded rod 93 drives the slider 11 to slide along the slide groove 10. At the same time, the second motor 13 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the cleaning roller 16 to rotate to clean the surface of the photovoltaic panel 2. At the same time, the suction and blowing dual-purpose fan 27 is started through the control mechanism 6, so that the suction and blowing dual-purpose fan 27 generates an inward suction force, and cooperates with the exhaust channel 19 to suck the dust cleaned by the cleaning roller 16 along the opening, thereby realizing the collection of dust. Secondly, when the cleaning roller 16 moves to the infrared When the line sensor 3 is turned on, the first motor 91 is reversed, thereby driving the cleaning roller 16 to reset. At this time, when the cleaning roller 16 needs to be air-dried, the control mechanism 6 is used to make the suction and blowing dual-purpose fan 27 generate wind force to blow outward, so that the cleaning roller 16 is air-dried by strong wind, which speeds up the air-drying efficiency of the cleaning roller 16 and avoids the phenomenon that water on the cleaning roller 16 accumulates inside and causes mold or even damage. This solves the problem that the brush roller of the existing photovoltaic solar panel absorbs a large amount of water after contacting with water and cannot quickly spin off the water on the brush roller, thereby causing most of the water to accumulate inside the brush roller, causing mold or even damage inside the brush roller.
