Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel cleaning, and particularly relates to a photovoltaic panel cleaning mechanism. Background Art

[0002] A photovoltaic panel, also known as a solar panel or a photovoltaic cell panel, is a device that directly converts light energy into electrical energy; tilting the photovoltaic panel can maximize the reception of sunlight radiation, improve the light collection efficiency of the photovoltaic panel, and can also be cleaned by natural rainfall to help remove part of the dust, dirt and other impurities, and keep the surface of the photovoltaic panel clean;

[0003] When it rains, after the rain washes the dust on the photovoltaic panel down, there will be some sewage staying at the seal between the photovoltaic panel and the bottom frame. If the sewage is not processed in time, after the sewage is dried by the sun, the sediment in the sewage will form a dirt block on the surface at the bottom of the photovoltaic panel, which not only reduces the light collection efficiency, but also is prone to local hot spot effect, affecting the service life of the photovoltaic panel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 - 3, the present utility model provides the following technical solutions: including: a mounting table 1, an I-shaped rail 7, and a sewage suction head 503. A connecting rod 2 is fixedly arranged on the top of the mounting table 1. The top of the connecting rod 2 is fixedly connected with a bearing 201. A rotating shaft 202 is fixedly sleeved inside the bearing 201. One end of the rotating shaft 202 is fixedly connected with a motor 3. The other end of the rotating shaft 202 is fixedly connected with a gear 4. A connecting pipe 5 is fixedly arranged at the top end of the mounting table 1. A fixing rod 501 is fixedly arranged on the side wall of the connecting pipe 5. The end of the fixing rod 501 away from the connecting pipe 5 is rotatably connected with a limiting wheel 6. A sewage suction head 503 is arranged at the top of the connecting rod 2. The suction end of the sewage suction head 503 is attached to the surface of the photovoltaic panel 8; the top of the I-shaped rail 7 is fixedly connected to the bottom end of each photovoltaic panel 8. The width of the top surface of the I-shaped rail 7 is the same as the width of the bottom end of the photovoltaic panel 8. Two track grooves 701 are opened on both sides of the I-shaped rail 7. A rack 702 is arranged on the lower wall of one of the track grooves 701. The width of the other track groove 701 is equal to the outer diameter of the limiting wheel 6. The rack 702 and the gear 4 are meshed with each other.

[0017] In this implementation scheme: the connecting rod 2 and the connecting pipe 5 are respectively arranged on the top of the mounting table 1. The connecting rod 2 and the connecting pipe 5 are symmetrically arranged on the mounting table. The top end of the connecting rod 2 is rotatably connected with the rotating shaft 202 through the bearing 201. The motor 3 drives the rotating shaft 202 to rotate, thereby driving the gear 4 at the other end of the rotating shaft 202 to rotate. The connecting pipe 5 is fixedly connected with the limiting wheel 6 through the fixing rod 501. And the connecting pipe 5 is of a hollow structure. A sewage suction head 503 is arranged at its top end. The connecting pipe 5 has the function of transporting sewage; the I-shaped rail 7 is installed at the bottom end of the photovoltaic panel 8. The track groove 701 with a rack 702 on one side of the I-shaped rail 7 is used to accommodate the gear 4. The other track groove 701 fits the outer circular surface of the limiting wheel 6. After starting the motor 3, the gear 4 moves on the rack 702 to drive the movement of the rotating shaft 202, thereby driving the movement of the connecting rod 2. The mounting table 1 fixed to the connecting rod 2 will also move accordingly. The connecting pipe 5 fixed on the mounting table 1, the sewage suction head 503 fixed on the top of the connecting pipe 5, and the fixing rod 501 fixed on the side wall of the connecting pipe 5 will all move simultaneously. The limiting wheel 6 on the fixing rod 501 fits the groove wall of the track groove 701. When the gear 4 moves on the rack 702 and moves in the track groove 701 at the same time, it can limit the position of the gear 4 and ensure that the gear 4 will not be disengaged when moving on the rack. The sewage suction head 503 moves parallel above the photovoltaic panel 8 following the device, continuously cleaning the muddy water at the bottom frame of the photovoltaic panel 8.

[0018] A cavity is formed inside the installation table 1, and a sewage suction mechanism 101 is fixedly arranged on the inner wall of the installation table 1. The bottom end of the connecting pipe 5 penetrates through the upper wall of the installation table 1 and is communicated with the sewage suction mechanism 101. The output end of the sewage suction mechanism 101 is fixedly provided with a sewage discharge port 102, and the output end of the sewage discharge port 102 penetrates through the bottom wall of the installation table 1. By forming a cavity inside the installation table 1 to place the sewage suction mechanism 101, sewage enters the sewage suction mechanism 101 from the upper connecting pipe 5 and flows out from the sewage discharge port 102 at the bottom wall of the installation table 1, optimizing the layout of the device and reducing the occupied space of the device.

[0019] A traveling wheel 502 is rotatably sleeved on the surface of the connecting pipe 5, and the traveling wheel 502 is located between the fixed rod 501 and the sewage suction head 503. The traveling wheel 502 can move synchronously with the device on the surfaces of the bottom frame and the I-shaped rail 7, further enhancing the stability of the device during walking, reducing the shaking of the brush bristles 504 and the sewage suction head 503, and enabling the brush bristles 504 and the sewage suction head 503 to move more stably on the surface of the photovoltaic panel 8.

[0020] The bearing 201 is a cylindrical roller bearing 201. The cylindrical roller bearing 201 can bear a large radial force, ensure the normal rotation of the bearing 201 in an inclined state, and increase the service life of the device.

[0021] The sewage suction head 503 is threadedly connected to the connecting pipe 5. After the sewage suction head has been used for a long time, it may need to be cleaned or replaced. The threaded connection between the sewage suction head 503 and the connecting pipe 5 facilitates the regular cleaning or replacement of the sewage suction head 503 during the later use of the device, so as not to affect the cleaning effect of the device.

[0022] Brush bristles 504 are fixedly arranged on the side wall of the sewage suction head 503, and the brush bristles 504 abut against the surface of the bottom frame of the lower photovoltaic panel 8. There may be sediment with strong adhesion in the sewage. The arrangement of the brush bristles 504 can lift the mud and ash with greater adhesion in the sewage, making the mud and ash easier to enter the sewage suction head 503 and enhancing the cleaning effect of the device.

[0023] The working principle and usage process of the present utility model: Install the gears and limit wheels of the device in the track grooves on both sides of the I-shaped rail. At this time, the gears fixed on the rotating shaft are meshed with the racks in the track grooves, and the limit wheels rotating on the fixed rod are in mutual contact with the inner wall of the other track groove. After the rain stops, start the motor to drive the gears to move on the racks inside the track grooves, driving the rotating shaft to move, thereby driving the installation table and the sewage suction mechanism to move along the length direction of the photovoltaic panel. The brush head at the bottom frame fits to lift the mud and dust with strong adhesion in the sewage water. Through the sewage suction head fixed above the photovoltaic panel, the sewage accumulated at the bottom frame of the photovoltaic panel is cleaned, and then transported through the connecting pipe to the sewage suction mechanism inside the installation table and discharged from the sewage discharge port at the bottom wall of the installation table.
