The efficient cleaning and maintenance of these panels is crucial for ensuring the efficiency of photovoltaic power generation. Currently, most photovoltaic power plants use photovoltaic cleaning robots to accomplish this task.

[0003] Currently, when existing photovoltaic cleaning robots need to replace a row of photovoltaic panels during the cleaning process, the replacement must be done manually, using a transport vehicle, or a separate photovoltaic cleaning robot must be installed for each row of photovoltaic panels. Installing a separate photovoltaic cleaning robot for each row would undoubtedly impose extremely high equipment procurement and installation costs on photovoltaic power plants.

[0004] However, current transport vehicles are difficult to move between multiple rows of photovoltaic panels due to their large size or complex and varied arrangements. Therefore, there is an urgent need for a transport vehicle that can be used to transport cleaning robots between multiple photovoltaic panels. Utility Model Content

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] Existing applications of photovoltaic cleaning robots have many pain points:

[0037] High installation costs: Installing a photovoltaic cleaning robot on each row of photovoltaic panels will undoubtedly impose extremely high equipment procurement and installation costs on photovoltaic power plants. Calculations show that this cost investment is far less cost-effective than the economic benefits brought by the increased power generation after cleaning, severely impacting the return on investment of photovoltaic projects.

[0038] Low cleaning efficiency: When faced with large-area photovoltaic power plants, photovoltaic cleaning robots that operate independently in a single row cannot quickly move to other rows to carry out cleaning work, resulting in long overall cleaning time. This fails to meet the need for timely cleaning of photovoltaic panels and thus affects the continuous improvement of photovoltaic power generation efficiency.

[0039] Cross-row technical challenges: How to achieve efficient and stable cross-row operation of photovoltaic cleaning robots has always been a technical bottleneck that the industry urgently needs to overcome. Traditional cleaning robots lack effective cross-row mechanisms, making it difficult for them to move flexibly between different rows of photovoltaic panels, which greatly limits their operating range and efficiency.

[0040] This utility model discloses a road transport vehicle. (See attached diagram.) Figure 1 -Appendix Figure 4 A type of road transport vehicle mainly includes a traveling mechanism 100, a mounting platform 200, a supporting mechanism 300, and a controller. The mounting platform 200 is fixedly installed on the upper end of the traveling mechanism 100, and the supporting mechanism 300 is fixedly installed on the mounting platform 200. The controller can be installed inside the vehicle body of the transport vehicle, so it is not marked, or it can be a mobile control platform.

[0041] The support mechanism 300 includes an identification component 310, a fixing plate 320, a docking plate 330, and a first push cylinder 340. The bottom end of the fixing plate 320 is fixedly connected to the top end of the mounting platform 200. One end of the docking plate 330 is hinged to one end of the fixing plate 320. One end of the first push cylinder 340 is hinged to the mounting platform 200. The telescopic rod end of the first push cylinder 340 is hinged to the bottom end of the docking plate 330. The identification component 310 is disposed on the docking plate 330 and is used to identify the distance between the docking plate 330 and the photovoltaic panel. The identification component 310, the first push cylinder 340, and the walking mechanism 100 are electrically connected to the controller.

[0042] By employing a walking mechanism 100, a mounting platform 200, and a support mechanism 300, this design ensures stable movement of the transport vehicle and provides a reliable platform for carrying and transporting the photovoltaic cleaning robot. The support mechanism 300 includes an identification component 310, a fixing plate 320, a docking plate 330, and a first push cylinder 340, which, under the control of the controller, allows the equipment to flexibly adjust its position and accurately align with the photovoltaic panels.

[0043] In some embodiments, the fixing plate 320 and / or the docking plate 330 are solar panels. In one embodiment, both the fixing plate 320 and the docking plate 330 are solar panels, or one of the fixing plate 320 or the docking plate 330 is a solar panel. When the charging mechanism 500 is not present, the fixing plate 320 and / or the docking plate 330 can supplement or power the vehicle body and / or the identification component 310 and / or the walking mechanism 100 of the transport vehicle, maintaining the normal operation of the transport vehicle, while saving the power consumption of the transport vehicle and reducing energy waste; when the transport vehicle delivers the photovoltaic cleaning robot to the photovoltaic panel, the fixing plate 320 and / or the docking plate 330 can capture and convert light energy to generate electricity with a larger area.

[0044] In some embodiments, the identification component 310 includes a first sensor 311, which is fixedly mounted on the docking plate 330 and located at the end of the docking plate 330 away from the fixed plate 320. The first sensor 311 is electrically connected to the controller. The first sensor 311 of the identification component 310 detects and locates the bottom edge of the photovoltaic panel to be cleaned and sends the detection signal to the controller. This enables the first push cylinder 340 to adjust the edge of the docking plate 330 towards the edge of the photovoltaic panel to be cleaned based on the detected position and distance information, and complete the docking. Then, the cleaning robot moves from the fixed plate 320 to the photovoltaic panel to be cleaned via the docking plate 330 to perform the cleaning operation. When the cleaning is completed and a panel replacement is required, the cleaning robot returns from the photovoltaic panel to the top of the fixed plate 320 and then moves to the next position using the walking mechanism 100.

[0045] In some embodiments, the identification component 310 further includes a second sensor 312, which is fixedly mounted on the docking plate 330 and located at the same end of the docking plate 330 as the first sensor 311. The second sensor 312 is electrically connected to the controller. The second sensor 312 detects the position relative to the edge of the photovoltaic panel. The second sensor 312 and the first sensor 311 cooperate to detect the distance and send the detection signal to the controller for adjustment, so that the edge of the photovoltaic panel can be aligned with the edge of the docking plate 330, reducing the occurrence of misalignment, improving docking accuracy, and reducing the possibility of the cleaning robot falling off.

[0046] In some embodiments, the identification component 310 further includes a third sensor 313, of which multiple third sensors 313 are provided and fixedly mounted on the docking plate 330 and the fixing plate 320; the second sensor 313 is electrically connected to the controller. The third sensor 313 detects the environment around the transport vehicle and sends the detection signal to the controller for adjustment. During the movement of the transport vehicle, it can detect the distance between surrounding objects, reducing the possibility of collision between the transport vehicle and the photovoltaic panel and improving the safety of the transport vehicle during its movement.

[0047] In some embodiments, a positioning and navigation module 400 is also provided on the mounting platform 200, and the positioning and navigation module 400 is electrically connected to the controller. During the movement of the transport vehicle, the positioning and navigation module 400 determines the position and route of the transport vehicle. The controller reads the navigation position information, and under the control of the controller, the transport vehicle is positioned and navigated by the walking mechanism 100 along a pre-set travel trajectory. At the same time, while the transport vehicle is moving along the trajectory set by the navigation module in conjunction with the walking mechanism 100, multiple third sensors 313 are used to measure and detect the surrounding environment. Based on the positions of surrounding objects directly obtained by the third sensors 313, automatic obstacle avoidance is achieved during the movement, reducing the possibility of collision between the transport vehicle and surrounding objects, and also reducing the possibility of collision between the transport vehicle and the photovoltaic panel, thereby improving the safety of the photovoltaic panel and the transport vehicle.

[0048] In some embodiments, a charging mechanism 500 is also provided on the fixed plate 320. The charging mechanism 500 includes a support frame 510 and a solar panel 520. The bottom end of the support frame 510 is fixedly connected to the upper end of the fixed plate 320, and the solar panel 520 is fixedly connected to the top end of the support frame 510. A power source (not shown) is provided on the mounting platform 200 or inside the vehicle, and the solar panel 520 is electrically connected to the power source. By setting up the charging mechanism 500, the transport vehicle can be recharged by the solar panel 520, thereby saving the power consumption of the transport vehicle and further reducing the operating cost. Specifically, the solar panel transmits the generated electrical energy to the boost controller inside the vehicle. The boost controller then adjusts the voltage of the electrical energy and stores it in the power source (battery). When charging is needed, based on the light energy obtained by the solar panel 520, when not in operation, the transport vehicle is moved to a location with good light source by means of the navigation module, the walking mechanism 100 and the third sensor 313, and then automatically replenishes energy to improve the energy replenishment efficiency and improve the automation level of the transport vehicle.

[0049] In some embodiments, the charging mechanism 500 further includes an adjusting frame 530 and a second telescopic cylinder 540. One end of the adjusting frame 530 is hinged to the top of the support frame 510, and the telescopic rod of the second telescopic cylinder 540 is hinged to the bottom end of the adjusting frame 530. The second telescopic cylinder 540 is electrically connected to the controller. Under the control of the controller, the angle of the adjusting frame 530 is adjusted by the second telescopic cylinder 540, thereby adjusting the angle of the solar panel 520. This allows the angle of the solar panel 520 to be adjusted according to the angle of sunlight, thereby improving the charging efficiency.

[0050] In some embodiments, the mounting platform 200 is further provided with a lifting mechanism 600, which includes a third telescopic cylinder 610. One end of the third telescopic cylinder 610 is fixedly connected to the top end of the traveling mechanism 100, and the telescopic rod of the third telescopic cylinder 610 is fixedly connected to the bottom end of the mounting platform 200. The third telescopic cylinder 610 is electrically connected to the controller. Under the control of the controller, by setting up the lifting mechanism 600, the height of the mounting platform 200 can be adjusted at any time according to the height of the photovoltaic panel, thereby enabling the transport vehicle to be suitable for photovoltaic panel cleaning work in different height environments and improving the applicability of the transport vehicle.

[0051] In some embodiments, the lifting mechanism 600 further includes a guide rail 620, a first lifting frame 630, and a second lifting frame 640. Two sets of guide rails 620 are provided, one set of guide rails 620 is fixedly installed on the bottom of the mounting platform 200, and the other set of guide rails 620 is fixedly installed on the top of the traveling mechanism 100. One end of the first lifting frame 630 is hinged to the mounting platform 200, and the other end of the first lifting frame 630 is hinged to one end of the traveling mechanism 100. One end of the second lifting frame 640 is slidably connected to the guide rail 620 at the top of the traveling mechanism 100, and the other end of the second lifting frame 640 is slidably connected to the guide rail 620 at the bottom of the mounting platform 200. One end of the third telescopic cylinder 610 is hinged to the first lifting frame 630, and the telescopic rod of the third telescopic cylinder 610 is hinged to the second lifting frame 640.

[0052] When the height of the mounting platform 200 needs to be adjusted, the distance to nearby objects is sensed by the third sensor 313 to avoid collisions. The position of the bottom edge of the photovoltaic panel is detected by the first sensor 311 and the second sensor 312. The height is adjusted by the third telescopic cylinder 610 to determine whether the lifting height is in place, thus improving the accuracy of the connection. During the lifting process, the traveling mechanism 100 stops to stabilize the vehicle body. Then, the telescopic rod of the third telescopic cylinder 610 extends and retracts. The magnetic control switch on the third telescopic cylinder 610 precisely controls the extension and retraction stroke of the telescopic rod to adjust the lifting height. During the extension and retraction of the telescopic rod of the third telescopic cylinder 610, one end of the first lifting frame 630 rotates on the traveling mechanism 100, and the other end rotates at the bottom of the mounting platform 200. Both ends of the second lifting frame 640 slide within the guide rail 620 to achieve height adjustment of the mounting platform 200. Through the guide rail 620, the first lifting frame 630, and the second lifting frame 640, the stability and safety of the lifting mechanism 600 during the lifting process are improved.

[0053] In some embodiments, the traveling mechanism 100 includes a traveling pulley 110 and a frame 120. The traveling pulley 110 is rotatably disposed on both sides of the frame 120, and the bottom end of the mounting platform 200 is fixedly mounted on the upper end of the frame 120. The traveling mechanism 100 can drive the transfer vehicle to travel via the traveling pulley 110, and can also achieve circumferential rotation to adjust the docking angle of the docking plate 330.

[0054] The implementation principle of a road transport vehicle according to this utility model embodiment is as follows:

[0055] Therefore, a tracked transport vehicle was designed to assist photovoltaic cleaning robots in crossing rows, referred to as the "road transport vehicle." The road transport vehicle is suitable for both single photovoltaic cleaning robots and cascaded photovoltaic cleaning robots. The road transport vehicle navigates using an RTK module based on existing trajectories. Obstacle avoidance and precise docking with photovoltaic panels are achieved through ultrasonic sensors. It transports the photovoltaic cleaning robot from one row of photovoltaic panels to another, thus assisting the robot in crossing rows, significantly improving the cleaning efficiency of photovoltaic panels and greatly reducing installation costs.

[0056] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
