[0002] The photovoltaic panels of a photovoltaic power station need to be regularly cleaned to ensure their normal operation. Given the large floor area of the photovoltaic power station, automatic cleaning equipment is usually used for the cleaning work of the photovoltaic panels. At present, most of the automatic cleaning equipment uses crawlers as the traveling device. However, since the ground around the photovoltaic panels is usually not hardened, the crawlers are severely worn during use.

[0003] The patent with the Chinese patent publication number CN221986520U discloses a design scheme of a traveling device, a chassis and a photovoltaic cleaning robot. By detachably connecting the traveling device to the vehicle frame, when the traveling device is damaged or excessively consumed and needs to be replaced, the traveling device can be directly detached from the vehicle frame for replacement, enabling rapid assembly and disassembly. Thus, the traveling device can be replaced or maintained as needed without disassembling the entire device, improving the maintenance efficiency of the device, reducing the maintenance cost, and making the replacement process simpler and faster.

[0004] Although the above solution can quickly restore the function of the device for cleaning the photovoltaic panels by directly replacing the traveling device, in a photovoltaic power station, multiple photovoltaic cleaning robots are usually deployed. Therefore, when multiple robots need to replace the traveling device, the photovoltaic power station needs to be equipped with a sufficient number of traveling devices for replacement, which will lead to an increase in the maintenance cost.

Detailed implementation manners

[0023] In order to further understand the features, technical means and the specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and the specific implementation manners.

[0024] Refer to Figures 1 to 8As shown: a photovoltaic cleaning robot which is easy to maintain and replace, includes a cleaning device and a walking device, the walking device includes a walking platform 1 and two walking mechanisms 2; a mounting bracket 11 for mounting the cleaning device is provided at the upper end of the walking platform 1; the two walking mechanisms 2 are respectively arranged at both ends of the walking platform 1, the walking mechanism 2 includes a mounting plate 21, two adjusting mechanisms 22, two second driving structures 23 and two walking structures 24, the mounting plate 21 is arranged on the walking platform 1, and the two ends of the mounting plate 21 extend to the two sides of the walking platform 1 respectively, the two adjusting mechanisms 22 are respectively arranged at the two ends of the mounting plate 21, the adjusting mechanism 22 includes a rotating arm 221 and a first driving structure 222, one end of the rotating arm 221 is provided with a first rotating shaft 2211, the first rotating shaft 2211 is connected to the mounting plate 21 through a bearing seat, the first driving structure 222 is arranged above the rotating arm 221, and the first driving structure 222 is transmission-connected to the first rotating shaft 2211, the first driving structure 222 includes a first rotating arm 221 The first rotary driver 2221, the driving gear 2222 and the driven gear 2223 are installed on the mounting plate 21, the driving gear 2222 is connected to the output shaft of the first rotary driver 2221, the driven gear 2223 is installed on the first rotating shaft 2211, and the driven gear 2223 is meshed with the driving gear 2222, the second driving structure 23 is arranged below the walking platform 1, and the second driving structure 23 is connected to the other end of the rotating arm 221, and the walking structure 24 is arranged at the lower end of the second drive structure 23, and the walking structure 24 is transmission-connected to the second drive structure 23. The walking structure 24 includes a second connecting bracket 241, a wheel frame 242 and a crawler track 243. The wheel frame 242 is arranged at the lower end of the first connecting bracket 231. A driving wheel 2421 and a plurality of driven wheels 2422 are arranged inside the wheel frame 242. The driving wheel 2421 is connected to the second drive structure 23, and the crawler track 243 is connected to the driving wheel 2421 and the plurality of driven wheels 2422.

[0025] When the photovoltaic cleaning robot is in normal operation, its four walking structures 24 are arranged in a four-point rectangle at the lower end of the walking platform 1 to ensure the stability of the walking platform 1. When one of the walking structures 24 is severely worn, maintenance personnel need to carry out maintenance. First, use equipment such as a jack to lift the walking platform 1, so that the severely worn walking structure 24 is suspended, which is convenient for maintenance personnel to disassemble the walking structure 24 from the main body of the photovoltaic cleaning robot. After disassembly, the adjustment mechanism 22 at the other end of the mounting plate 21 is used to drive another walking structure 24 to adjust its working state to ensure the balance of the walking platform 1. The first driving structure 222 in the adjustment mechanism 22 is started to drive the rotating arm 221 to operate. The first rotary driver 2221 drives the first rotating shaft 2211 to rotate through the meshing of the driving gear 2222 and the driven gear 2223, so that the rotating arm 221 rotates 180 degrees, thereby rotating the walking structure 24 at one end of the rotating arm 221 to the middle position of the mounting plate 21. At this time, the remaining three walking structures 24 can still form a stable triangular support system to maintain the stability of the walking platform 1, and there is no need to immediately replace the spare walking structure 24. Under the stable support formed by the three walking structures 24, the three corresponding second driving structures 23 drive these three walking structures 24 to operate at the same time, so that the walking device continues to move smoothly and continue to clean the photovoltaic panel. The maintenance personnel take the severely worn walking structure 24 back for centralized maintenance. After the maintenance is completed, the walking structure 24 is reinstalled on the photovoltaic cleaning robot, so that there is no need to equip too many spare walking structures 24, effectively reducing the maintenance cost.

[0026] Refer to Figure 3 and Figure 4 As shown: The second driving structure 23 includes a first connecting bracket 231 and a second rotary driver 232; both ends of the first connecting bracket 231 are provided with second rotating shafts 2311. One end of the second rotating shaft 2311 is fixedly connected to the second connecting bracket 241, and the other end of the second rotating shaft 2311 is connected to the rotating arm 221 through a bearing. The walking structure 24 is hoisted at the lower end of the first connecting bracket 231; the second rotary driver 232 is arranged at the upper end of the first connecting bracket 231, and the output shaft of the second rotary driver 232 passes through the first connecting bracket 231 downward and is in transmission connection with the walking structure 24.

[0027] The gravity acting on the second rotary drive 232 and the traveling structure 24 is concentrated on the first connection bracket 231. When the traveling structure 24 is located on one side of the traveling platform 1, the rotating arm 221 is in a horizontal state. At this time, if the first drive structure 222 drives the rotating arm 221 to rotate, the first connection bracket 231 will rotate around the axis of the second rotating shaft 2311 under the combined action of the gravity of the second rotary drive 232 and the traveling structure 24. During the rotation process, it is ensured that the bottom of the crawler 243 in the traveling structure 24 always remains parallel to the ground, so as to ensure that the traveling structure 24 can walk normally after being adjusted to the middle position of the mounting plate 21.

[0028] Refer to Figure 3 and Figure 5 As shown: The traveling mechanism 2 further includes a connection structure 25. The connection structure 25 is arranged between the second drive structure 23 and the traveling structure 24. The connection structure 25 includes two first connection plates 251 and two second connection plates 252. The two first connection plates 251 are respectively arranged on both sides of the lower part of the first connection bracket 231. One end of the first connection plate 251 is connected to the first connection bracket 231, and a first docking hole is opened at the other end of the first connection plate 251. The two second connection plates 252 are respectively arranged below the two first connection plates 251. One end of the second connection plate 252 is connected to the second connection bracket 241, and a second docking hole is opened at the other end of the second connection plate 252.

[0029] As a vulnerable part, the crawler 243 has a high replacement frequency. If the second drive structure 23 and the traveling structure 24 are designed as a whole, the two need to be removed as a whole when replacing the crawler 243, resulting in a long time-consuming disassembly and installation process. To optimize the disassembly efficiency, the second drive structure 23 and the traveling structure 24 are set in a split state and connected through the connection structure 25. After the first docking hole on the first connection plate 251 in the connection structure 25 and the second docking hole on the second connection plate 252 are coaxially aligned, bolts are used to fixedly connect the first connection plate 251 and the second connection plate 252, realizing the stable connection between the first connection bracket 231 and the second connection bracket 241. When it is necessary to disassemble the traveling structure 24, only the bolts in the connection structure 25 need to be unscrewed, and the first connection plate 251 and the second connection plate 252 can be easily separated, thus realizing the separate disassembly of the traveling structure 24 and improving the disassembly efficiency.

[0030] Refer to Figure 3 and Figure 6As shown in the figure: The second driving structure 23 further includes a first transmission disk 233, a second transmission disk 234, and a transmission shaft 235; the first transmission disk 233 is arranged at the output shaft end of the second rotary driver 232, and the axis of the first transmission disk 233 is collinear with the output shaft of the second rotary driver 232. A plurality of first transmission teeth 2331 are annularly arranged on the surface of the first transmission disk 233 facing away from the second rotary driver 232; the second transmission disk 234 is arranged at the lower end of the first transmission disk 233, and a plurality of second transmission teeth 2341 are annularly arranged on the surface of the second transmission disk 234 facing the first transmission disk 233; the transmission shaft 235 is arranged at the lower end of the second transmission disk 234, and both ends of the transmission shaft 235 are respectively connected to the second transmission disk 234 and the traveling structure 24.

[0031] Since the traveling structure 24 and the second driving structure 23 can be separated, when connecting the two, it is necessary to quickly establish a transmission path to ensure that the second driving structure 23 can effectively drive the traveling structure 24 to operate. Therefore, the first transmission disk 233, the second transmission disk 234, and the transmission shaft 235 are provided. The first transmission disk 233 is connected to the output shaft of the second rotary driver 232, and the second transmission disk 234 and the transmission shaft 235 are connected to the traveling structure 24. When the traveling structure 24 is disassembled, the second transmission disk 234 and the transmission shaft 235 will be disassembled together with the traveling structure 24. When reconnecting the traveling structure 24 and the second driving structure 23, a plurality of second transmission teeth 2341 on the second transmission disk 234 need to be engaged with a plurality of first transmission teeth 2331 on the first transmission disk 233. Once the engagement is completed, the second rotary driver 232 can drive the first transmission disk 233 to rotate. The first transmission disk 233 drives the second transmission disk 234 to rotate further through the engaged first transmission teeth 2331 and second transmission teeth 2341. Finally, the second transmission disk 234 drives the traveling structure 24 to operate through the transmission shaft 235, thus realizing the rapid and effective connection of the transmission path between the second driving structure 23 and the traveling structure 24.

[0032] Refer to Figure 6 and Figure 7 As shown in the figure: The second driving structure 23 further includes an elastic connection assembly 236. The elastic connection assembly 236 is arranged between the second rotary driver 232 and the first transmission disk 233. The elastic connection assembly 236 includes a fixed disk 2361. The fixed disk 2361 is coaxially arranged with the first transmission disk 233. A plurality of guide posts 2362 are annularly arranged on the fixed disk 2361. The guide posts 2362 are slidably connected to the fixed disk 2361, and one end of the guide post 2362 is fixedly connected to the first transmission disk 233. A spring 2363 is sleeved on each guide post 2362. Both ends of the spring 2363 are respectively abutted against the fixed disk 2361 and the first transmission disk 233.

[0033] When the position of the first drive disk 233 is fixed, it is necessary to ensure that while the first connecting plate 251 is docked with the second connecting plate 252, the first drive disk 233 and the second drive disk 234 can successfully engage with each other. Since these two processes need to be synchronously controlled, the complexity of the connection is increased. Therefore, an elastic connection structure 25 is provided. A number of springs 2363 in the elastic connection structure 25 exert a downward force on the first drive disk 233, driving the guide post 2362 away from the fixed disk 2361. During the docking process of the second drive structure 23 and the traveling structure 24, the first drive disk 233 will dock with the second drive disk 234 first. Due to the action of the spring 2363, the first drive disk 233 can be in close contact with the second drive disk 234, effectively preventing the two from falling off. Subsequently, the docking of the first connecting plate 251 and the second connecting plate 252 is carried out. Thus, by means of step-by-step connection, the difficulty of connecting the second drive structure 23 and the traveling structure 24 is significantly reduced.

[0034] Refer to Figure 1 、 Figure 3 and Figure 8 As shown in: The traveling mechanism 2 further includes two fixing mechanisms 26. The two fixing mechanisms 26 respectively correspond to the two adjusting mechanisms 22. The fixing mechanism 26 includes a first fixing component 261 and a second fixing component 262. The first fixing component 261 and the second fixing component 262 are respectively arranged on both sides of the adjusting mechanism 22. The first fixing component 261 and the second fixing component 262 are both hoisted at the lower end of the mounting plate 21. The structures of the first fixing component 261 and the second fixing component 262 are the same. The first fixing component 261 includes a hoisting plate 2611, a plug rod 2612 and a linear drive 2613. The upper end of the hoisting plate 2611 is connected to the mounting plate 21. The plug rod 2612 is slidably arranged in the middle of the hoisting plate 2611. A fixing jack for docking with the plug rod 2612 is provided on the side surface of the rotating arm 221.

[0035] When the photovoltaic cleaning robot walks on the undulating ground, the upward force received by its traveling structure 24 will constantly change. When this upward force exceeds the control force of the first drive structure 222 on the rotating arm 221, the traveling structure 24 may rise upward, which may cause the traveling platform 1 to tilt. Therefore, the fixing mechanism 26 is provided. After the first drive structure 222 completes the adjustment of the position of the rotating arm 221, the linear drive 2613 will drive the plug rod 2612 to move towards the rotating arm 221 and insert the plug rod 2612 into the fixing jack. Through the cooperation of the plug rod 2612 and the first rotating shaft 2211, it can be ensured that the position of the rotating arm 221 remains unchanged, thereby effectively avoiding the tilt of the photovoltaic cleaning robot during walking due to the undulation of the ground, and improving the stability and cleaning efficiency of the robot.

[0036] The above embodiments merely represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
