Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, and more specifically, it relates to an anti-slip track and a photovoltaic cleaning machine. Background Technology

[0002] After prolonged use, photovoltaic (PV) panels require regular surface cleaning to ensure cleanliness, thereby guaranteeing efficient sunlight reception and ultimately, high power generation efficiency. Cleaning often requires the use of PV cleaning machines. These machines clean the PV panels as they move across the panels. However, since many PV panels are installed at an angle, the tracks on the cleaning machine often lack sufficient grip at larger angles, leading to slippage. Chinese Patent Application No. 202510657593 7 discloses a PV panel cleaning device with a flat track surface, resulting in low grip and a tendency to slip when moving across inclined PV panels. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an anti-slip track and a photovoltaic cleaning machine. The anti-slip track has a large grip and is not prone to slippage during operation, thus ensuring the smooth movement of the photovoltaic cleaning machine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an anti-slip track, including a track body, a plurality of adsorption grooves are arranged at intervals along the circumference of the track body on the outer surface of the track body, and an air suction hole is provided on the bottom surface of the adsorption groove to draw air into the adsorption groove and generate negative pressure in the adsorption groove, and the air suction hole extends through to the inner surface of the track body.

[0005] During operation, the lower outer surface of the anti-slip track contacts the supporting surface, and under the action of friction, it moves forward and backward. During this process, air is drawn into the adsorption tank through the air intake holes, thereby creating negative pressure in the adsorption tank, increasing the adsorption force between the adsorption tank and the supporting surface, and preventing the anti-slip track from slipping. Existing tracks will slip when running on a 15-degree incline, while the anti-slip track of this application can run smoothly on an incline of up to 40 degrees.

[0006] The anti-slip track of this patent application has a large grip and is not prone to slippage during operation, thus ensuring the smooth movement of the photovoltaic cleaning machine.

[0007] Preferably, a number of protruding transmission teeth are provided at intervals along the circumference of the track body on the inner surface of the track body.

[0008] The transmission teeth on the inner surface of the track body mesh with the gear ring on the transmission wheel to ensure reliable transmission of the track body.

[0009] Preferably, the transmission tooth cross-section has a "D" shaped structure.

[0010] Transmission gears with a "D" shaped cross-section are less prone to slippage between themselves and transmission wheels.

[0011] Preferably, the transmission teeth are arranged in two rings, and a mating plane is formed between the two rings of transmission teeth on the inner surface of the track body, with the air intake opening end placed on the mating plane.

[0012] The mating surface is placed between two rings of transmission teeth. After the anti-slip track is installed on the photovoltaic cleaning machine, the suction hood installed on the photovoltaic cleaning machine fits smoothly and reliably onto the mating surface with good sealing performance. The transmission teeth on both sides play a blocking and positioning role for the suction hood.

[0013] Preferably, a recessed groove is provided on both sides of the outer surface of the track body in the width direction, and the adsorption groove is placed between the two recessed grooves.

[0014] The design of the sinking groove makes the area around the adsorption tank more easily deformable, thereby improving the sealing between the adsorption tank and the support surface and ensuring the adsorption effect.

[0015] Preferably, the track body includes an inner belt and an outer belt connected together, the outer belt being a flexible body, and the adsorption groove is disposed on the outer surface of the outer belt.

[0016] The outer layer is a flexible material that is easily deformable, thereby improving the sealing between the adsorption tank and the support surface and ensuring the adsorption effect.

[0017] Preferably, the adsorption tank has a cylindrical slotted structure.

[0018] The cylindrical groove-shaped adsorption tank is easy to manufacture.

[0019] Another option is to use a conical groove structure for the adsorption tank.

[0020] The adsorption tank with a conical groove structure has a good adsorption effect.

[0021] Preferably, a sealing lip is provided at the opening end of the adsorption tank, and the sealing lip is higher than the outer surface of the track body.

[0022] The sealing lip is supported on the support surface, which greatly improves the sealing between the adsorption tank and the support surface, ensuring the adsorption effect.

[0023] A photovoltaic cleaning machine includes a body with anti-slip tracks connected to both sides of the body. An air suction hood corresponding to the anti-slip tracks is installed on the body. The air suction hood is pressed against the inner surface of the lower side of the anti-slip tracks, and the air suction holes can pass through the air suction hood and be covered by the air suction hood.

[0024] The anti-slip track drives the photovoltaic cleaning machine forward. The exhaust device draws air from the suction hood, which then draws air from the suction holes to the adsorption tank on the anti-slip track. This creates negative pressure in the adsorption tank, increasing the adsorption force between the adsorption tank and the supporting surface, preventing the anti-slip track from slipping, and enabling the photovoltaic cleaning machine to operate reliably on an inclined surface with a maximum tilt angle of 40 degrees.

[0025] Compared with the prior art, the beneficial effects of this utility model are: (1) The anti-slip track of this patent application has a large gripping force and is not prone to slippage during operation, thus ensuring the smooth movement of the photovoltaic cleaning machine; (2) The contact plane is placed between two rings of transmission teeth, and the suction hood installed on the photovoltaic cleaning machine is attached to the contact plane smoothly and reliably, with good sealing performance. The transmission teeth on both sides play a blocking and positioning role for the suction hood; (3) The track body includes an inner belt body and an outer belt body connected together. The outer belt body is a flexible body and is easy to deform, thereby improving the sealing performance between the adsorption tank and the support surface and ensuring the adsorption effect; (4) A sealing lip is provided at the opening end of the adsorption tank. The sealing lip is supported on the support surface, which greatly improves the sealing performance between the adsorption tank and the support surface and ensures the adsorption effect.

Figure 1 , Figure 2 The system includes a track body 1. Several adsorption grooves 2 are spaced circumferentially along the outer surface of the track body 1. Each adsorption groove 2 has a cylindrical slotted structure, and the grooves are evenly spaced with adjacent grooves close to each other. Suction holes 3 are provided on the bottom surface of each adsorption groove 2 to draw air in and create negative pressure within the groove. The diameter of the suction holes 3 is much smaller than the diameter of the adsorption groove 2, and the suction holes 3 extend to the inner surface of the track body 1.

[0034] The track body 1 includes an inner belt body 4 and an outer belt body 5 connected together. The outer belt body 5 is a flexible body and can be made of rubber. The hardness of the inner belt body 4 is greater than that of the outer belt body 5. The adsorption groove 2 is set on the outer surface of the outer belt body 5, and the air intake hole 3 penetrates through the outer belt body 5 and the inner belt body 4. The outer belt body 5 is a flexible body and is easily deformable, thereby improving the sealing between the adsorption groove 2 and the supporting surface and ensuring the adsorption effect.

[0035] Several raised transmission teeth 6 are spaced along the circumference of the inner surface of the track body 1. The transmission teeth 6 have a "D" shaped cross-section. The transmission teeth 6 on the inner surface of the track body 1 mesh with the gear ring on the transmission wheel 10 to ensure reliable transmission of the track body 1. The "D" shaped cross-section of the transmission teeth 6 makes it less prone to slippage between the transmission teeth 6 and the transmission wheel 10. There are two rings of transmission teeth 6, and a contact plane 7 is formed between the two rings of transmission teeth 6 on the inner surface of the track body 1. The opening end of the air intake hole 3 is placed on the contact plane 7. The contact plane 7 is placed between the two rings of transmission teeth 6. After the anti-slip track is installed on the photovoltaic cleaning machine, the air intake hood 9 installed on the photovoltaic cleaning machine fits stably and reliably onto the contact plane 7 with good sealing performance. The transmission teeth 6 on both sides play a blocking and positioning role for the air intake hood 9.

A water pump is installed on the machine body 14. The water inlet of the water pump is connected to the water storage chamber, and the water outlet of the water pump is connected to the inside of the cleaning covers 11.

[0038] The anti-slip track supports the photovoltaic panel surface, driving the photovoltaic cleaning machine forward. A ventilation system draws air from the suction hood 9, which in turn draws air through the suction holes 3 to the adsorption grooves 2 on the anti-slip track. This creates negative pressure within the adsorption grooves 2, increasing the adsorption force between the grooves 2 and the supporting surface, preventing slippage of the anti-slip track, and enabling the photovoltaic cleaning machine to operate reliably on an inclined surface with a maximum tilt angle of 40 degrees. During cleaning, a water pump operates, spraying water from the cleaning hood 11, and the brush rollers 12 clean the photovoltaic panel surface.
