Water from cleaning the panels irrigates the grass below, and animals are introduced to perform biological weed control, maintaining vegetation height and preventing excessive vegetation from blocking sunlight. This design achieves a "photovoltaic-pasture-livestock" trinity model.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] A photovoltaic panel maintenance device, such as Figure 1 、 Figure 2-Figure 7 As shown:

[0038] It includes a mobile cart 4, and a robotic arm 5 and a cleaning component 41 mounted on the mobile cart 4. The robotic arm 5 can be a six-axis robotic arm; the cleaning component 41 can be a brush roller or other structure; the mobile cart 4 is equipped with a visual recognition system. The above components are all existing technologies and will not be repeated here. The user can remotely control it through the control panel according to the real-time image transmitted by the visual recognition system, or realize automatic control based on the cooperation of the visual recognition system and AI.

[0039] The cleaning assembly 41 is provided with a nozzle for spraying water, and the mobile vehicle 4 is not provided with a water tank to reduce the weight.

[0040] Each group of photovoltaic panels 100 is provided with a group of joint mother bodies 21 and upright poles 3. The joint mother bodies 21 adopt a normally closed structure for connection with an external water source.

[0041] The output end of the robot arm 5 is provided with a connecting assembly 7, which includes a cylinder 8 and a joint male body 9;

[0042] The cylinder 8 has a spring turntable 81 built into it, and the second delivery hose 82 is wrapped around the spring turntable 81. One end of the second delivery hose 82 is connected to the first delivery hose 6, and the other end of the second delivery hose 82 is connected to the rotary connector 92; the other end of the first delivery hose 6 is connected to the delivery pipe in the cleaning assembly 41.

[0043] The cylinder 8 has a built-in driver 83 , which can be a motor. The output end of the driver 83 is connected to a first external spline tooth 84 .

[0044] A connecting hole 85 communicating with the interior of the cylinder 8 is provided on one side. A limiting groove 851 of an annular structure is provided on the inner wall of the connecting hole 85. The inner diameter of the connecting hole 85 is larger than the outer shape of the rotary connector 92 so that the rotary connector 92 can enter and exit.

[0045] A valve body 91 is provided at one end of the male connector 9, which is in communication with the inner cavity of the valve body 91. A rotary connector 92 is provided at one end of the valve body 91. A water hole 93, a valve core 94, and a first elastic member 95 are provided in the valve body 91. The two ends of the first elastic member 95 are respectively connected to the valve core 94 and the inner wall of the valve body 91. The elastic force of the first elastic member 95 pushes the valve core 94 to close the water hole 93 under normal conditions.

[0046] The outer wall of the valve body 91 is a circular structure and is provided with second external spline teeth, which mesh with the first external spline teeth 84 .

[0047] The outer wall of the joint male body 9 is provided with a slide groove 96, and the slide groove 96 is connected to the limit column 97 in a liquid-tight sliding manner. A pull rope is connected between the limit column 97 and the valve core 94. Figure 5A second elastic member (not shown in the drawings) is provided in the chute 96 . The elastic force of the second elastic member is less than the elastic force of the first elastic member 95 . Under normal conditions, the elastic force of the second elastic member pushes the limiting post 97 out of the chute 96 .

[0048] The connector body 21 and the connector body 9 form a quick connector, which is threadedly connected to each other. The upper end of the vertical rod 3 is configured to be threadedly connected to the connector body 9. The connector body 9 has a built-in permanent magnet. The connector body 21 and the upper end of the vertical rod 3 are made of iron and magnetically cooperate with the connector body 9.

[0049] Working principle:

[0050] The mobile trolley 4 moves on the outer surface of the photovoltaic panel 100, and controls the robotic arm 5 to move the male connector 9 in its end connection assembly 7 to align with the female connector 21. Then, the driver 83 drives the first external spline teeth 84 to rotate. The rotation of the first external spline teeth 84 drives the valve body 91 to rotate along with the second external spline teeth that mesh with each other. The rotation of the valve body 91 drives the male connector 9 to rotate. During this process, the robotic arm 5 continuously applies pressure to push the male connector 9 into the female connector 21, thereby achieving a threaded connection between the male connector 9 and the female connector 21.

[0051] When the male connector 9 and the female connector 21 are threadedly connected together, the female connector 21 is in an open state, so that the external water source is transported to the delivery pipe connection in the cleaning component 41 through the female connector 21, the male connector 9, the valve body 91, the rotary connector 92, the second delivery hose 82, and the first delivery hose 6 in sequence, that is, the external water source can supply water to the cleaning component 41.

[0052] When water flows in the valve body 91 toward the cleaning assembly 41, the water flow pushes the valve core 94 to open the water through hole 93. The first elastic member 95 generates a reverse elastic force, pushing the valve core 94 away from the water through hole 93. During this process, the valve core 94 drives the limiting post 97 to move along with it via the pull rope, so that the outer end of the limiting post 97 is withdrawn from the limiting groove 851.

[0053] Afterwards, the control robot arm 5 drives the cylinder 8 at its output end away from the connector male body 9. At this time, the connector male body 9 and the connector female body 21 are connected as one, so that the valve body 91 can be pulled out from the connecting hole 85 without hindrance during this process. The first external spline teeth 84 and the second external spline teeth on the outer wall of the valve body 91 adopt a straight tooth structure, which is conducive to the separation of the valve body 91 from each other during the process of being pulled out from the connecting hole 85. During this process, the second delivery hose 82 is adapted by the pull rope, and the spring turntable 81 generates a reverse elastic force.

[0054] Thereafter, the mobile trolley 4 can be controlled to move on the upper surface of the photovoltaic panel 100 , and the second delivery hose 82 can be automatically stretched or retracted to adapt, and the cleaning component 41 sprays water for washing during the movement of the mobile trolley 4 .

[0055] When the cleaning component 41 no longer sprays water outward, the water in the valve body 91 does not flow. Under normal circumstances, the elastic force of the first elastic member 95 pushes the valve core 94 to close the water hole 93; then, the limiting column 97 is pushed by the second elastic member so that the outer end of the limiting column 97 extends to the outside of the slide groove 96.

[0056] After cleaning the photovoltaic panel 100, the control arm 5 moves the cylinder 8 in its end connection assembly 7 to align with the connector male body 9, and controls the valve body 91 to be relatively inserted into the connection hole 85, so that the second external spline teeth of the valve body 91 are engaged with the first external spline teeth 84. At this time, the outer end of the limiting column 97 is just inserted into the limiting groove 851 of the connection hole 85, thereby realizing the connection of the cylinder 8 and the connector male body 9. After that, the driver 83 drives the first external spline teeth 84 to rotate in the opposite direction, and the reverse rotation of the first external spline teeth 84 drives the connector male body 9 to follow the reverse rotation, thereby realizing the separation of the connector male body 9 and the connector mother body 21.

[0057] Then, the robotic arm 5 is controlled to drive the connector male body 9 at its output end to be inserted into the upper end of the vertical pole 3, so that the connector male body 9 and the upper end of the vertical pole 3 are threadedly connected and fixed. Then, the robotic arm 5 drives the mobile car 4 in the reverse direction with the fixed vertical pole 3 as support to move to another adjacent group of photovoltaic panels 100.

[0058] The overall weight of the mobile trolley 4 can be greatly reduced by removing the water tank.

[0059] Example 2: Contains all the contents of Example 1, except that Figure 1 、 Figure 2 As shown:

[0060] Each group of photovoltaic panels 100 is provided with a guide rail 1, a slider 2 is slidably connected inside the guide rail 1, a connector body 21 is provided on the slider 2 and can slide freely, and the connector body 21 is connected to an external water source through a third delivery hose.

[0061] In order to reduce the weight of the mobile trolley 4, the length of the second delivery hose 82 is limited, while the photovoltaic panel 100 is relatively long. At this time, the connector mother 21 moves on the guide rail 1 through the slider 2 to compensate for the insufficient length of the second delivery hose 82.

[0062] Example 3: includes all the contents of Example 1 or 2, except that:

[0063] A one-way damping layer 971 is provided on the outer wall of the limiting column 97. When the valve core 94 is pushed open by the water flow, the friction resistance between the one-way damping layer 971 and the inner wall of the chute 96 is very small, which is conducive to driving the limiting column 97 to retract into the chute 96, so that the outer end of the limiting column 97 can quickly disengage from the limiting groove 851.

[0064] When the limiting post 97 extends outward from the chute 96, the friction resistance between the one-way damping layer 971 and the inner wall of the chute 96 is large, so that the limiting post 97 extends outward from the chute 96 at a slow speed.

[0065] The setting of the one-way damping layer 971 is conducive to connecting the connector mother body 21 and the connector male body 9 into one body. When the external water source supplies water to the cleaning component 41, after the limit column 97 disengages from the limit groove 851, the limit column 97 extends outward at a slower speed under the push of the second elastic member, which is conducive to providing more time for the valve body 91 to be pulled out of the connecting hole 85.

[0066] Example 4: includes all the contents of Example 3, except that:

[0067] like Figure 7 As shown, the one-way damping layer 971 includes a plurality of deformable bodies arranged at equal intervals along the moving direction of the limiting column 97. The deformable bodies are made of elastic material. The outer wall of the limiting column 97 is liquid-tightly matched with the inner wall of the chute 96 through the deformable bodies made of elastic material. Friction layers with different friction coefficients are respectively provided on opposite sides of the deformable bodies.

[0068] Since the deformable body can deform within a certain range, when the limiting post 97 is retracted into the chute 96, the friction layer with a very low friction coefficient on one side of the deformable body contacts the inner wall of the chute 96;

[0069] When the limiting post 97 extends from the sliding groove 96 , the friction layer with a larger friction coefficient on the other side of the deformation body contacts the inner wall of the sliding groove 96 .

[0070] The above descriptions are merely embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent structures or equivalent process changes made using the contents of the present invention's description and drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present invention's patent protection.
