Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cleaning, and particularly relates to a photovoltaic cleaning robot delivery system. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight, and is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials. With the vigorous development of new energy, the number of installed photovoltaic panels is increasing.

[0003] Since the photovoltaic panels of a photovoltaic array generate electricity using solar energy, the surface of the photovoltaic panels needs to be kept clean to efficiently utilize solar energy. For the cleaning of photovoltaic panels in traditional centralized photovoltaic power stations, usually, after workers drive a vehicle to the site, they get out of the vehicle and place the cleaning robot in the vehicle on the photovoltaic panels for cleaning. Manual delivery requires a great deal of physical strength from the workers, and the efficiency of manual delivery gradually decreases as physical strength decreases. Summary of the Utility Model

[0004] In view of this, the utility model provides a photovoltaic cleaning robot delivery system to solve one of the problems in the prior art.

[0005] In a first aspect, the utility model provides a photovoltaic cleaning robot delivery system, which comprises:

[0006] A transport device;

[0007] A robotic arm, arranged on the transport device;

[0008] A cleaning member, arranged on the transport device and adapted to be detachably connected to the robotic arm, and the robotic arm is configured to control the cleaning member to clean a target area of a photovoltaic panel;

[0009] A cleaning robot, arranged on the transport device and detachably connected to the robotic arm, and the robotic arm is configured to transfer the cleaning robot from the transport device to the target area.

[0010] Beneficial effects: The photovoltaic cleaning robot delivery system transports the robotic arm, cleaning component, and cleaning robot to the area where the photovoltaic panels are installed through a transport device, which is simple, fast, and labor-saving. When the transport device moves into position, the robotic arm first grabs the cleaning component and uses the cleaning component to clean the target area of the photovoltaic panel. After cleaning, the robotic arm places the cleaning component back on the transport device, then grabs the cleaning robot on the transport device and transfers it to the cleaned target area. The surface of the cleaned target area is relatively clean with less dust and debris, enabling the cleaning robot to stably land on the target area and preventing the cleaning robot from rolling off the photovoltaic panel due to reduced friction caused by excessive dust. When the cleaning robot finishes cleaning the entire photovoltaic panel, the robotic arm will grab the cleaning robot and place it back on the transport device, completing the cleaning of a single photovoltaic panel. This photovoltaic cleaning robot delivery system has a high degree of automation and high working efficiency, greatly reducing the physical labor workload of the staff, and thus effectively reducing the attenuation of the delivery efficiency.

[0011] In an optional embodiment, the cleaning component includes a connecting portion and a cleaning portion. The robotic arm is detachably connected to the connecting portion, and the connecting portion is hinged to the cleaning portion.

[0012] Beneficial effects: By hinging the connecting portion to the cleaning portion, it can not only achieve a firm connection between the robotic arm and the connecting portion but also enable relative movement between the cleaning portion and the connecting portion. When cleaning a photovoltaic panel with a certain inclination angle, it can achieve a better cleaning effect. The cleaning portion that can rotate flexibly can effectively clean the target area and reduce the possibility of damaging the photovoltaic panel.

[0013] In an optional embodiment, the cleaning portion includes a mounting plate, a brush, and a first convex block. The brush is arranged at the bottom of the mounting plate, and the first convex block is arranged at the top of the mounting plate; the connecting portion includes a connecting plate and a second convex block. The robotic arm is detachably connected to the connecting plate, and the second convex block is hinged to the first convex block.

[0014] Beneficial effects: Through the hinging of the first convex block and the second convex block, the mounting plate can rotate relative to the connecting plate, enabling the brush to adapt to a photovoltaic panel with an inclination angle, improving the cleaning effect while reducing the possibility of damaging the photovoltaic panel.

[0015] In an optional embodiment, there are two first convex blocks and three second convex blocks. The three second convex blocks are spaced apart to form two grooves, and the two first convex blocks are respectively located in the two grooves.

[0016] Beneficial effects: By setting two first convex blocks and three second convex blocks, the connection firmness between the mounting plate and the connecting plate can be enhanced, and its service life can be extended.

[0017] In an alternative embodiment, the free end of the robotic arm includes at least two suction cups, and the at least two suction cups are evenly spaced.

[0018] Advantageous effects: Grabbing the cleaning part or the cleaning robot by the suction cup is simple and firm, which can reduce the possibility of the cleaning part or the cleaning robot falling when the free end of the robotic arm moves. The two suction cups are evenly spaced to further enhance the grabbing ability and ensure the safety of the cleaning part and the cleaning robot.

[0019] In an alternative embodiment, the free end of the robotic arm includes a fixed rod and at least two mounting rods. The at least two mounting rods are arranged on the same side of the fixed rod, and at least one suction cup is arranged on any one of the mounting rods.

[0020] Advantageous effects: The fixed rod enables a certain distance between the suction cup and the mounting rod, providing a certain space for the cleaning part and the cleaning robot, avoiding interference between the cleaning part and the cleaning robot and the free end of the robotic arm, and thus reducing the possibility of the robotic arm not grabbing firmly.

[0021] In an alternative embodiment, an L-shaped rod is further installed on the fixed rod. The L-shaped rod is fixed on the same side of the fixed rod as the mounting rod, and a vision sensor is arranged at one end of the L-shaped rod, and the field of view of the vision sensor faces downward.

[0022] Advantageous effects: The L-shaped rod enables the field of view of the vision sensor to face downward. The vision sensor enables the robotic arm to perform precise grabbing operations, ensuring that the free end of the robotic arm can accurately move to the positions of the cleaning part and the cleaning robot with a smaller volume for grabbing, and improving the grabbing efficiency.

[0023] In an alternative embodiment, the transportation device is a vehicle, and the vehicle is provided with a receiving cavity, and the robotic arm, the cleaning part, and the cleaning robot are located in the receiving cavity.

[0024] Advantageous effects: Transportation by vehicle is highly efficient and low-cost, and the receiving cavity of the vehicle has sufficient space to accommodate the robotic arm, the cleaning part, and the cleaning robot, and can provide sufficient working space for the robotic arm.

[0025] In an alternative embodiment, the delivery system further includes:

[0026] A robot base station, arranged on the transportation device, and the cleaning robot is adapted to be charged and / or self-cleaned in the robot base station.

[0027] Beneficial effects: By providing a robot base station, the cleaning robot can be charged and / or self-cleaned, thus extending the operation time of the cleaning robot. After the cleaning robot has been cleaning for a certain period of time, its battery power and cleaning strength will be greatly reduced, affecting subsequent cleaning operations. Therefore, by placing the cleaning robot in the robot base station for charging and / or cleaning, its battery power and cleaning ability can be restored, ensuring that the cleaning robot can complete the corresponding task volume.

[0028] In an alternative embodiment, the robot base station includes a cleaning module, and the cleaning module is adapted to clean the crawler of the walking wheels of the cleaning robot.

[0029] Beneficial effects: By cleaning the crawler of the walking wheels of the cleaning robot with the cleaning module, the climbing ability of the cleaning robot can be effectively improved, avoiding excessive dust contamination on the crawler and reducing the friction with the photovoltaic panel, thereby reducing the possibility of the cleaning robot slipping off the photovoltaic panel and ensuring the safety of the cleaning robot.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0046] The following combines Figures 1 to 7 , Multiple photovoltaic panels 101 form a photovoltaic array 100, and an embodiment of the photovoltaic cleaning robot delivery system of the present utility model is described.

[0047] According to an embodiment of the present invention, on the one hand, a photovoltaic cleaning robot delivery system is provided. The photovoltaic cleaning robot delivery system includes a transport device 1, a robotic arm 2, a cleaning component 3, and a cleaning robot 4. The robotic arm 2 is disposed on the transport device 1; the cleaning component 3 is disposed on the transport device 1 and is adapted to be detachably connected to the robotic arm 2. The robotic arm 2 is configured to manipulate the cleaning component 3 to clean a target area of the photovoltaic panel 101. After the robotic arm 2 is connected to the cleaning component 3, it controls the cleaning component 3 to clean an area of the photovoltaic panel 101. After the cleaning is completed, the cleaning component 3 is placed on the transport device 1 and detached from the cleaning component 3. The cleaning robot 4 is disposed on the transport device 1 and is detachably connected to the robotic arm 2. The robotic arm 2 is configured to transfer the cleaning robot 4 from the transport device 1 to the target area. After an area of the photovoltaic panel 101 is cleaned by the cleaning component 3, the robotic arm 2 is disconnected from the cleaning component 3 and connected to the cleaning robot 4. The robotic arm 2 transfers the cleaning robot 4 to the area of the photovoltaic panel 101 that has been cleaned by the cleaning component 3.

[0048] The photovoltaic cleaning robot delivery system provided in this embodiment transports the robotic arm 2, the cleaning component 3, and the cleaning robot 4 to the area where the photovoltaic array 100 is installed through the transport device 1, which is simple, fast, and labor-saving. When the transport device 1 moves into place, first, the robotic arm 2 grabs the cleaning component 3, and the cleaning component 3 cleans the target area of the photovoltaic panel 101. After the cleaning, the robotic arm 2 places the cleaning component 3 back on the transport device 1, then grabs the cleaning robot 4 on the transport device 1 and transfers it to the cleaned target area. The surface of the cleaned target area is relatively clean with less dust and debris, enabling the cleaning robot 4 to stably land on the target area and preventing the cleaning robot 4 from rolling off the photovoltaic panel 101 due to reduced friction caused by excessive dust. Moreover, the area where the cleaning robot 4 is to be placed is pre-cleaned by the cleaning component 3, avoiding the problem that this area cannot be effectively cleaned because it is occupied by the cleaning robot 4.

[0049] When the cleaning of the entire photovoltaic panel 101 by the cleaning robot 4 is completed, the robotic arm 2 grabs the cleaning robot 4 and places it back on the transport device 1, completing the cleaning of a single photovoltaic panel 101. This photovoltaic cleaning robot delivery system has a high degree of automation and high working efficiency, greatly reducing the physical labor workload of the staff, and thus effectively reducing the attenuation of the delivery efficiency.

[0050] It should be noted that the robotic arm 2 can be any multi-degree-of-freedom robotic arm 2, which is convenient for placing the cleaning component 3 or the cleaning robot 4 in the required area and minimizing the manual workload as much as possible; the cleaning robot 4 can be any cleaning robot 4 capable of sweeping dust and debris.

[0051] In one embodiment, the cleaning member 3 includes a connecting portion 31 and a cleaning portion 32. The robotic arm 2 is detachably connected to the connecting portion 31, and the connecting portion 31 is hinged to the cleaning portion 32. By hinging the connecting portion 31 to the cleaning portion 32, not only can the stable connection between the robotic arm 2 and the connecting portion 31 be achieved, but also the relative movement between the cleaning portion 32 and the connecting portion 31 can be realized. When cleaning the photovoltaic panel 101 with a certain inclination angle, a better cleaning effect can be obtained. The cleaning portion 32 that can rotate flexibly can effectively clean the target area, and at the same time, the possibility of damaging the photovoltaic panel 101 by the cleaning portion 32 can be reduced.

[0052] In one embodiment, the cleaning portion 32 includes a mounting plate 321, a brush 322, and a first convex block 323. The brush 322 is disposed at the bottom of the mounting plate 321, and the first convex block 323 is disposed at the top of the mounting plate 321; the connecting portion 31 includes a connecting plate 311 and a second convex block 312. The robotic arm 2 is detachably connected to the connecting plate 311, and the second convex block 312 is hinged to the first convex block 323. The first convex block 323 extends from the top of the mounting plate 321 and is smaller than the size of the mounting plate 321. The second convex block 312 extends from the connecting plate 311 and is smaller than the size of the connecting plate 311. By hinging the first convex block 323 to the second convex block 312, the mounting plate 321 can rotate relative to the connecting plate 311, so that the brush 322 can adapt to the photovoltaic panel 101 with an inclination angle, improving the cleaning effect while reducing the possibility of damaging the photovoltaic panel 101.

[0053] In one embodiment, there are two first convex blocks 323 and three second convex blocks 312. The three second convex blocks 312 are spaced apart to form two grooves 313, and the two first convex blocks 323 are respectively located in the two grooves 313. By providing two first convex blocks 323 and three second convex blocks 312, the connection stability between the mounting plate 321 and the connecting plate 311 can be enhanced, and its service life can be extended. In other embodiments, more or fewer first convex blocks 323 and second convex blocks 312 can also be provided according to the size of the brush 322.

[0054] In one embodiment, as Figure 7 shown, the cleaning robot 4 includes a robot body 41 and a connecting block 42. The connecting block 42 is disposed on the top of the robot body 41, and the robot body 41 is connected to the robotic arm 2 through the connecting block 42.

[0055] In one embodiment, as Figure 4 and Figure 7As shown, the free end of the robotic arm 2 includes at least two suction cups 21, and the at least two suction cups 21 can be evenly spaced. Grabbing the cleaning part 3 or the cleaning robot 4 through the suction cup 21 is simple and firm, which can reduce the possibility of the cleaning part 3 or the cleaning robot 4 falling when the free end of the robotic arm 2 moves. The two suction cups 21 are evenly spaced to further enhance the grabbing ability and ensure the safety of the cleaning part 3 and the cleaning robot 4.

[0056] No specific type of the suction cup 21 is limited herein. In this embodiment, both of the two suction cups 21 are vacuum suction cups 21, which have mature technology, low cost and firm grabbing.

[0057] In this embodiment, when the robotic arm 2 is connected to the cleaning part 3, it is connected by adsorbing to the connecting plate 311 of the cleaning part 3 through the suction cup 21; when the robotic arm 2 is connected to the cleaning robot 4, it is connected by adsorbing to the top surface of the cleaning robot 4 through the suction cup 21.

[0058] In one embodiment, as Figure 7 shown, the free end of the robotic arm 2 includes a fixed rod 22 and at least two mounting rods 23. The at least two mounting rods 23 are arranged on the same side of the fixed rod 22, and a preset distance is spaced between the two mounting rods 23. At least one suction cup 21 is arranged on any one of the mounting rods 23. The fixed rod 22 enables a certain distance between the suction cup 21 and the mounting rod 23, and can be more stable when using the suction cup to adsorb the cleaning part 3 and the cleaning robot 4.

[0059] In one embodiment, an L-shaped rod 24 is further installed on the fixed rod 22. The L-shaped rod 24 is fixed on the same side of the fixed rod 22 as the mounting rod 23. One end of the L-shaped rod 24 is provided with a vision sensor 241, and the field of view of the vision sensor 241 faces downward. Through the L-shaped rod 24, the field of view of the vision sensor 241 can be set downward. The vision sensor 241 enables the robotic arm 2 to perform precise grabbing operations, ensuring that the free end of the robotic arm 2 can accurately move to the positions of the relatively small cleaning part 3 and the cleaning robot 4 for grabbing, and improving the grabbing efficiency.

[0060] In one embodiment, as Figure 1 shown, the transportation device 1 is a vehicle. The vehicle is provided with a receiving cavity 11, and the robotic arm 2, the cleaning part 3 and the cleaning robot 4 are located in the receiving cavity 11. Transportation by vehicle has high efficiency and low cost, and the receiving cavity 11 of the vehicle has enough space to accommodate the robotic arm 2, the cleaning part 3 and the cleaning robot 4, and can provide enough working space for the robotic arm 2.

[0061] No specific type of the vehicle is limited herein. It can be a pickup truck or a flatbed truck. The receiving cavity 11 has a large volume and can provide enough working space for the robotic arm 2.

[0062] In one embodiment, as Figure 1 shown, the delivery system further includes a robot base station 5. The robot base station 5 is arranged on the transport device 1, and the cleaning robot 4 is adapted to be charged and / or self-cleaned within the robot base station 5. By providing the robot base station 5, the cleaning robot 4 can be charged and / or self-cleaned, thereby extending the working time of the cleaning robot 4. After the cleaning robot 4 has been cleaning for a certain period of time, its battery power and cleaning intensity will be greatly reduced, affecting subsequent cleaning operations. Therefore, by placing the cleaning robot 4 in the robot base station 5 for charging and / or cleaning, its battery power and cleaning ability can be restored, ensuring that the cleaning robot 4 can complete the corresponding task volume.

[0063] In one embodiment, the robot base station 5 includes a cleaning module (not shown). The cleaning module is adapted to clean the crawler of the walking wheels of the cleaning robot 4. By cleaning the crawler of the walking wheels of the cleaning robot 4 with the cleaning module, the climbing ability of the cleaning robot 4 can be effectively improved, avoiding excessive dust contamination on the crawler and reducing the friction force with the photovoltaic panel 101, thereby reducing the possibility of the cleaning robot 4 slipping off the photovoltaic panel 101 and ensuring the safety of the cleaning robot 4.

[0064] In one embodiment, the cleaning module can also clean the cleaning components of the cleaning robot 4 to ensure the cleaning ability of the cleaning robot 4. The cleaning components of the cleaning robot 4 are used to clean the photovoltaic panel 101. When the cleaning components are dirty, they may not be able to effectively clean the photovoltaic panel. By using the cleaning module of the robot base station 5 to clean the cleaning components of the cleaning robot 4, the effective cleaning of the photovoltaic panel can be guaranteed.

[0065] In one embodiment, the robot base station 5 further includes a charging module. The charging module can store electrical energy and transmit the electrical energy to the cleaning robot 4 for charging, ensuring the cleaning ability and endurance of the cleaning robot 4.

[0066] There is no limitation on the number of the cleaning robots 4 and the cleaning parts 3 here. Multiple cleaning robots 4 and cleaning parts 3 can be arranged in the accommodation cavity 11 as needed. When the cleaning part 3 is damaged or has too much dirt attached and its cleaning intensity decreases, another cleaning part 3 can be replaced to continue the operation. Or when the cleaning robot 4 needs to be cleaned and charged, another cleaning robot 4 can be used to continue the cleaning operation, effectively improving the operation efficiency.

[0067] The general working process of the photovoltaic cleaning robot delivery system provided in this embodiment is as follows:

[0068] The staff operates the vehicle to move to the setting area of the photovoltaic array 100 and stops the vehicle beside the photovoltaic panel 101. After the vehicle stops stably, the staff starts the robotic arm 2 or the robotic arm 2 is automatically started by the system, so that the robotic arm 2 grabs the cleaning part 3 in the accommodating cavity 11 and cleans the target area on the photovoltaic panel 101 through the cleaning part 3. After the target area is cleaned, the robotic arm 2 puts the cleaning part 3 back into the accommodating cavity 11 and grabs the cleaning robot 4, and places the cleaning robot 4 on the cleaned target area to ensure that the cleaning robot 4 stays stably on the surface of the photovoltaic panel 101. After the robotic arm 2 disconnects from the cleaning robot 4, the cleaning robot 4 starts to perform the cleaning operation. When the cleaning operation is completed, the robotic arm 2 grabs the cleaning robot 4 again and puts it back into the accommodating cavity 11. The above completes the cleaning of one photovoltaic panel 101.

[0069] When the cleaning of one photovoltaic array 100 is completed, the staff operates the vehicle to the next photovoltaic array 100 and repeats the above steps for cleaning; when the cleaning of multiple photovoltaic arrays 100 is completed, or when the power of the cleaning robot 4 is low, the staff cleans and charges the cleaning robot 4 through the robot base station 5. At this time, the staff can continue the cleaning operation through another cleaning robot 4, and the two cleaning robots 4 work alternately until the cleaning of all cleaning components is completed.
