Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment cleaning, and particularly to a photovoltaic cleaning robot. Background Art

[0002] With the rapid development of the photovoltaic industry, the cleaning and maintenance of photovoltaic panels are crucial for ensuring power generation efficiency. However, there are still some significant deficiencies in the current photovoltaic cleaning robots during actual applications:

[0003] In terms of battery compatibility: The battery installation adaptability of existing photovoltaic cleaning robots is poor. Due to the differences in the power input directions of lithium batteries produced by different manufacturers, and the single design of the battery boxes of traditional robots, they cannot flexibly adapt to lithium batteries with different power input directions, resulting in great limitations for users when replacing batteries, increasing the usage cost and maintenance difficulty.

[0004] In terms of crawler reliability: When a photovoltaic cleaning robot operates on the complex surface of photovoltaic panels, the crawlers are prone to problems such as loosening and deviation due to terrain changes or long-term use. The traditional crawler structure lacks effective adjustment and tensioning mechanisms, directly affecting the normal driving and cleaning operation efficiency of the robot, and reducing its overall stability.

[0005] In terms of pulley support: In addition, the crawler pulleys of photovoltaic cleaning robots lack effective support structures, and are prone to damage during long-term operation or when dealing with complex terrains, thereby shortening the service life of the pulleys and reducing the working efficiency.

[0006] In terms of protective cover fixation: Traditional protective covers are usually fixed by bolts, buckles or adhesives, etc., and the installation process is cumbersome. When internal components need to be repaired, maintained or replaced, special tools must be used to spend a lot of time for disassembly. Operating in a narrow space may also cause scratches or loss of parts, and it is difficult to reuse. This fixation method is also prone to failure situations such as loosening, rusting or even breaking in the face of harsh working environments such as vibration and immersion in liquid.

[0032] To further illustrate each embodiment, the present invention provides accompanying drawings. These accompanying drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0033] Now, the present invention will be further described in conjunction with the accompanying drawings and the detailed implementation manners.

[0034] As Figure 1-8 shown, this embodiment provides a photovoltaic cleaning robot 1, including a robot body 10, a cleaning assembly 20, and a traveling assembly 30. The cleaning assembly 20 and the traveling assembly 30 are connected to the robot body 10. The cleaning assembly 20 is used to clean the surface of the photovoltaic device, and the traveling assembly 30 is used to move the photovoltaic cleaning robot 1 on the surface of the photovoltaic device. There are two sets of both the cleaning assembly 20 and the traveling assembly 30. It is defined that the two sets of traveling assemblies 30 are arranged on the left and right sides of the robot body 10, and the two sets of cleaning assemblies 20 are arranged on the front and back sides of the robot body 10. A power member (not shown) is provided inside the robot body 10. The power member includes, for example, a motor, etc., to provide the traveling power of the photovoltaic cleaning robot 1. Of course, in some embodiments, the power member can also be provided outside the robot body 10. For example, the power member can be integrated in the traveling assembly 30.

[0035] In this embodiment, a battery box 15 is further provided inside the robot body 10. The battery box 15 is used to install a battery to supply power to the robot. Two sets of electrode contacts are provided inside the battery box 15, namely a first electrode contact group 151 and a second electrode contact group 152. Among them, the first electrode contact group 151 includes contacts that are docked with the battery electrodes when the battery is installed conventionally in the forward direction, and the second electrode contact group 152 includes contacts that are docked with the battery electrodes when the battery is installed in the reverse direction. Through the ingenious design of the electrode contacts, whether the battery is placed upright or inverted, the correct connection between the robot circuit system and the lithium battery can be ensured, realizing stable power supply.

[0036] During installation, first open the upper box cover 11 of the robot, and judge the installation method of the battery according to the power input direction of the selected lithium battery. If the power input direction of the lithium battery matches the front electrode contacts of the battery box, place the battery face up into the battery box, and at the same time ensure that the electrode contacts on the front of the battery box are accurately aligned with the connection terminals of the internal circuit of the robot. If the power input direction of the lithium battery matches the back electrode contacts of the battery box, turn the lithium battery 180 degrees so that the back of the lithium battery faces up, and also align it with the installation slot for installation. After ensuring that the back electrode contacts are correctly connected to the connection terminals, install the upper box cover 11. This design greatly improves the flexibility of battery selection. Users can freely choose lithium batteries with different power input directions according to actual needs and market supply situations, reducing procurement costs and adaptation difficulties.

[0037] In this embodiment, as Figure 2 shown, a first strap 153 and a second strap 154 are provided inside the battery box 15, so as to be able to assist in fixing the battery inside the battery box 15 and improve the stability of battery installation.

[0038] Referring to Figure 3 - Figure 4 , the traveling assembly 30 includes a crawler 31, a pulley 32, a wheel axle 33, and a pulley support rod 34. The wheel axle 33 is provided at the center of the pulley 32, and the crawler 31 is sleeved outside the pulley 32. The traveling assembly 30 further includes a tensioning mechanism 35. The tensioning mechanism 35 includes a shaft seat 351, an adjusting bolt 352, and a limit block 353. The wheel axle 33 is installed on the shaft seat 351, the shaft seat 351 is movably installed on the robot body 10, the limit block 353 is fixedly installed on the robot body 10, a threaded hole is provided in the limit block 353, the adjusting bolt 352 is screwed into the threaded hole of the limit block 353, and the end of the adjusting bolt 352 abuts against the shaft seat 351. By rotating the adjusting bolt 352, the shaft seat 351 can be pushed to generate a displacement. Specifically, when the crawler becomes loose, rotate the adjusting bolt 352 forward, and the end of the adjusting bolt 352 pushes the shaft seat 351 to generate a displacement, thereby driving the pulley 32 installed thereon along as Figure 2Moving in the A direction shown in the figure, the belt pulley 32 presses the crawler belt 31, thereby increasing the tension of the crawler belt 31. During the adjustment process, the operator can observe the tension degree of the crawler belt 31 and the stability of the robot during walking, and stop the adjustment in a timely manner. When it is necessary to reduce the crawler belt tension or adjust the wheel axle center distance to adapt to the pitch of photovoltaic panels with different widths, rotate the adjustment screw in the reverse direction to move the slider inward, and the extrusion force of the belt pulley 32 on the crawler belt 31 is reduced to achieve the corresponding adjustment effect. In this way, it can effectively ensure that the crawler belt 31 is always in an appropriate tension state, avoid problems such as loosening and deviation, improve the stability and reliability of the robot walking on the surface of the photovoltaic panel, and ensure the efficient progress of the cleaning operation.

[0039] In this embodiment, the axle seat 351 can be installed on the chute of the robot body 10, and the axle seat 351 can slide smoothly on the chute, so as to realize the movable installation of the axle seat 351 on the robot body 10, making the adjustment smoother.

[0040] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 Figure, the belt pulley support rod 34 is installed at the outer end of the wheel axle 33 and is located outside the belt pulley 32; the outer end of the wheel axle 33 is the end far from the robot body 10, and the outside of the belt pulley 32 is the side far from the robot body 10. There are two shaft holes 341 on the belt pulley support rod 34, which are respectively installed with the outer ends of the two wheel axles 33. The belt pulley support rod 34 is made of a high-strength lightweight material, such as aluminum alloy, which can not only ensure sufficient strength to support the crawler belt pulley 32, but also reduce the overall weight of the robot. During the operation of the robot, when the crawler belt encounters an uneven photovoltaic panel surface or an obstacle, the belt pulley support rod 34 can play a buffering and supporting role, preventing the crawler belt pulley from being damaged due to excessive force, and at the same time keeping the wheel axle on the same center line.

[0041] A process groove 342 is formed on the inner side of the belt pulley support rod 34, and the process groove 342 is oblong. There can be multiple process grooves 342. In this embodiment, two process grooves 342 are shown. The process groove 342 can further reduce the weight of the belt pulley support rod 34 and can also ensure sufficient strength to support the crawler belt pulley 32. In addition, belt pulley support rods 34 with different lengths can be prepared to adapt to the photovoltaic cleaning robot 1 with different wheel axle center distances. Or, the belt pulley support rod 34 can be set to have an adjustable length structure to adapt to the photovoltaic cleaning robot 1 with different wheel axle center distances.

[0042] When installing the track wheel support rod 34, align the fixing hole with the wheel axle and install it. During daily maintenance, regularly check whether the connection parts are loose and whether the wheel support rod 34 itself is damaged. If any problems are found, repair or replace them in time to ensure that the track wheel support rod 34 can always function normally.

[0043] Through the above design, the photovoltaic cleaning robot 1 of this embodiment is significantly improved in terms of battery adaptability and track stability, and has high practical value and market competitiveness.

[0044] Reference Figure 1 The upper cover 11 of the photovoltaic cleaning robot 1 is also provided with an indicator light 12, a power display module 13 and a cover rotary switch 14. The indicator light 12 is used to indicate the working status of the photovoltaic cleaning robot 1. The power display module 13 is used to display the power of the battery in the battery box 15, so that the power of the photovoltaic cleaning robot 1 can be easily grasped. The cover rotary switch 14 is used to open the upper cover 11 by rotating, so as to facilitate the maintenance of internal parts. The upper cover 11 of the photovoltaic cleaning robot 1 is also connected to a water pipe guide device 17, which is used to guide the water pipe, and the water pipe can provide cleaning water to the cleaning component 20.

[0045] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The cleaning assembly 20 includes a roller brush 21, a power element 23, a transmission mechanism 24 and a protective cover 22. The transmission mechanism 24 includes a transmission sprocket 242 and a transmission chain 241. In this embodiment, the power element 23 is a motor. The power element 23 is connected to the roller brush 21 through the transmission mechanism 24 to drive the roller brush 21 to rotate. The protective cover 22 covers the transmission mechanism 24, thereby providing safety protection to prevent the transmission mechanism 24 from causing damage to personnel. The protective cover 22 includes a base plate 221 and a cover body 222. The base plate 221 and the cover body 222 are magnetically connected. During installation, it is only necessary to bring the cover body 222 close to the base plate 221 located on the side of the protected transmission mechanism 24, and the magnetic suction component will automatically adsorb to complete the rapid positioning and installation. During disassembly, the cover body 222 can be removed by applying external force to overcome the magnetic suction effect. The operation is simple and convenient. In addition, the adsorption force of the magnetic component has been carefully designed to ensure that the cover body 222 will not fall off during normal use and under certain vibration conditions, and will not be difficult to disassemble due to excessive adsorption force.

[0046] The cover body 222 includes a cover body housing 2221 and mounting posts 2222 protruding from the inside of the cover body housing 2221. A permanent magnet 2223 is mounted at the end of the mounting post 2222. The bottom plate 221 includes a magnetic attraction member 2211. The magnetic attraction member 2211 can generate a magnetic attraction force with the permanent magnet 2223 to achieve a magnetic attraction connection between the bottom plate 221 and the cover body 222, thereby firmly mounting the cover body 222 on the bottom plate 221. The magnetic attraction member 2211 can be a magnet or other magnetic materials such as iron, cobalt, nickel, etc.

[0047] The cover body 222 is made of a material with a certain strength and flexibility to ensure that it can effectively protect the covered item and adapt to the surfaces of items with different shapes. The shape of the cover body 222 is designed according to the shape of the protected item. In this embodiment, the cover body 222 is generally oval and can closely fit the contour of the protected item to provide all-round protection.
