Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel cleaning equipment, in particular to a sucker-fixed photovoltaic robot. Background Technique

[0002] Since photovoltaic panels are placed outdoors, after long-term use, dust and other attachments will adhere to the surface of the photovoltaic panels. These attachments will block light, thereby reducing the power generation efficiency of the photovoltaic panels. The role of the existing photovoltaic robots is mainly to keep the photovoltaic panels clean, thereby improving the power generation efficiency of the photovoltaic system.

[0003] When the photovoltaic robot rotates on the photovoltaic panel or encounters strong wind weather, due to the relatively smooth surface of the photovoltaic panel, the photovoltaic robot is prone to slip on the photovoltaic panel, thereby causing a position error, and even causing the photovoltaic robot to fall from the photovoltaic panel.

[0004] At present, the photovoltaic robot uses suckers to adsorb on the photovoltaic panel to maintain stability. However, since the suckers will give resistance to the driving mechanism after contacting the photovoltaic panel, the driving mechanism affected by the resistance interference cannot move the adsorption to the accurate height. The resistance causes the downward movement distance of the suckers to be insufficient, resulting in a decrease in the sealing performance between the suckers and the photovoltaic panel, and further causing a decrease in the adsorption force, making the photovoltaic robot more prone to slip on the surface of the photovoltaic panel and easily causing losses to the photovoltaic robot. Content of the Utility Model

[0005] The utility model aims to solve the above problems and provides a sucker-fixed photovoltaic robot, which solves the above problems.

[0006] A sucker-fixed photovoltaic robot includes: a mounting frame, a first bracket, a pushing and pulling device, a chute plate, a sucker and a connecting block. The mounting frame is fixedly connected to the vehicle body of the robot body. The sucker passes through the vehicle body of the robot body downward. The connecting block is fixed relative to the position of the sucker. The chute plate is formed with chutes having a height difference. The connecting block is connected to the chute. The pushing and pulling device drives the chute plate to move horizontally. The chute plate drives the connecting block to move vertically through the chute. The sucker moves vertically relative to the mounting frame.

[0007] Further, it further includes a sliding sleeve and a lifting pipe. The lower end of the lifting pipe is fixedly connected to the sucker. The sliding sleeve is fixed relative to the mounting frame. The lifting pipe passes through the sliding sleeve and is slidably connected to the sliding sleeve.

[0008] Further, it further includes a solenoid valve and an air pump. The solenoid valve is a two-position three-way valve. The lower end of the lifting pipe is connected to the sucker in communication. The upper end of the lifting pipe is connected to one interface of the solenoid valve in communication. The other two interfaces of the solenoid valve are respectively connected to the air extraction port and the air inflation port of the air pump in communication.

[0009] Further, the lifting pipe is fixedly connected to the connecting block.

[0010] Further, the sliding groove includes a high part, a connecting part, and a low part, and the high end and the low end of the connecting part are respectively communicated with the high part and the low part.

[0011] Further, it further includes bearings. Short shafts are respectively formed on the front and rear sides of the connecting block, the bearings are sleeved outside the short shafts, and the bearings are located in the sliding groove.

[0012] Further, it further includes a connecting plate. The left and right sides of the sliding groove plate are respectively fixedly connected to the connecting plate. The pushing and pulling device is a cylinder or an electric push rod, and the two ends of the left and right pushing and pulling devices are respectively fixedly connected to the mounting frame and the connecting plate.

[0013] Further, a first support is formed above the mounting frame, and the first support is fixedly connected to one end of the pushing and pulling device.

[0014] Further, it further includes a second support. The second support is located above the mounting frame and is fixedly connected to the upper part of the mounting frame, and the sliding sleeve is fixedly connected to the second support.

[0015] Further, it further includes a universal ball bearing. The universal ball bearing is fixedly connected to the second support and the ball part is in contact with the sliding groove plate.

[0016] The present utility model has the following advantages:

[0017] 1. By using a sliding groove with a height difference to drive the suction cup to move up and down, the working position of the suction cup during adsorption corresponds to the low position of the sliding groove, and the working position of the suction cup when not adsorbing corresponds to the high position of the sliding groove, so that the suction cup can move to an accurate position, ensuring the fitting and sealing effect with the photovoltaic panel, and further improving the position stability relative to the photovoltaic panel;

[0018] 2. Using two left and right pushing and pulling devices can provide a higher driving force for the suction cup;

[0019] 3. When it is necessary to stop the suction cup from adsorbing, an air pump is used to inflate the suction cup, and the air pressure in the suction cup changes quickly, accelerating the reaction speed of the robot;

[0020] 4. Using a universal ball bearing instead of the existing structure of a slider cooperating with a slide rail is lighter in weight. Description of the Drawings

[0033] As Figures 1 to 7 shown, a sucker-fixed photovoltaic robot includes: a mounting frame 1, a first bracket 11, a pushing and pulling device 2, a chute plate 3, a sucker 4, and a connecting block 5. The mounting frame 1 is fixedly connected to the vehicle body of the robot body 8. The sucker 4 passes downward through the vehicle body of the robot body 8. The connecting block 5 is fixed relative to the position of the sucker 4. The chute plate 3 is formed with chutes 31 having a height difference. The connecting block 5 is connected to the chutes 31. The pushing and pulling device 2 drives the chute plate 3 to move horizontally. The chute plate 3 drives the connecting block 5 to move vertically through the chutes 31. The sucker 4 moves vertically relative to the mounting frame 1.

[0034] Optionally, the sucker 4 is not externally connected to an air pump for exhausting air. After the sucker 4 contacts the surface of the photovoltaic panel, the pushing and pulling device 2 continues to press down the sucker 4, causing the sucker 4 to elastically deform and partially discharge the air inside it, thereby adsorbing the sucker 4 on the photovoltaic panel. This implementation has a simple structure and does not require additional air path components, but the adsorption force it can provide is relatively low.

[0035] Among them, the connection between the connecting block 5 and the chutes 31 includes direct connection and indirect connection through other components.

[0036] Direct connection: A part of the structure of the connecting block 5 extends into the chutes 31 and is slidably connected to the chutes 31.

[0037] Indirect connection: It further includes a bearing 52. Short shafts 51 are respectively formed on the front and rear sides of the connecting block 5. The bearing 52 is sleeved outside the short shafts 51, and the bearing 52 is located in the chutes 31. Among them, the bearing 52 is used to reduce friction and improve the smoothness of the movement of the connecting block 5.

[0038] Furthermore, it further includes a sliding sleeve 14 and a lifting tube 41. The lower end of the lifting tube 41 is fixedly connected to the sucker 4. The sliding sleeve 14 is fixed relative to the mounting frame 1. The lifting tube 41 passes through the sliding sleeve 14 and is slidably connected to the sliding sleeve 14. The sliding sleeve 14 and the lifting tube 41 cooperate to limit the lifting tube 41 so that it cannot move in the horizontal direction.

[0039] Further, it further includes a solenoid valve 6 and an air pump 7. The solenoid valve 6 is a two-position three-way valve. The lower end of the lifting pipe 41 is communicated with the suction cup 4, the upper end of the lifting pipe 41 is communicated with one interface of the solenoid valve 6, and the other two interfaces of the solenoid valve 6 are respectively communicated with the air suction port and the air inflation port of the air pump 7. The lifting pipe 41 has two functions of a slide bar and an air pipe, reducing the number of components and thus reducing the overall weight.

[0040] Further, the lifting pipe 41 is fixedly connected to the connecting block 5.

[0041] Further, the chute 31 includes a high part 301, a connecting part 302 and a low part 303. The high end and the low end of the connecting part 302 are respectively communicated with the high part 301 and the low part 303. The chute 31 moves horizontally, thereby driving the connecting block 5 to move up and down along the chute 31.

[0042] Further, it further includes a connecting plate 32. The left and right sides of the chute plate 3 are respectively fixedly connected to the connecting plate 32. The pushing and pulling device 2 is a cylinder or an electric push rod. The two ends of the left and right pushing and pulling devices 2 are respectively fixedly connected to the mounting frame 1 and the connecting plate 32. The connecting plate 32 serves to connect the chute plates 3 on the front and back sides.

[0043] Further, a first bracket 11 is formed above the mounting frame 1, and the first bracket 11 is fixedly connected to one end of the pushing and pulling device 2.

[0044] Further, it further includes a second bracket 12. The second bracket 12 is located above the mounting frame 1 and is fixedly connected to the upper part of the mounting frame 1, and the sliding sleeve 14 is fixedly connected to the second bracket 12.

[0045] Further, it further includes a universal ball bearing 13. The universal ball bearing 13 is fixedly connected to the second bracket 12 and the spherical part thereof contacts the chute plate 3. The universal ball bearing 13 is used to support the chute plate 3, and the weight is lighter than that of the existing slider and slide rail.

[0046] When the robot changes direction (rotates in place) and encounters strong wind, the pushing and pulling device 2 pushes the chute plate 3 to move left and right. The bearing 52 originally located in the high part 301 is pressured by the chute 31 and moves in the chute 31 until the bearing 52 moves downward through the connecting part 302 to the low part 303. At this time, the lower end of the suction cup 4 fits with the surface of the photovoltaic panel, playing a sealing role.

[0047] After that, the air pump 7 sucks air. The air in the suction cup 4 passes through the lifting pipe 41 to the air suction port of the air pump 7, and finally is discharged to the outside from the third port of the air pump 7. A vacuum degree is generated in the suction cup 4, thereby adsorbing the suction cup 4 on the surface of the photovoltaic panel. The robot can remain stationary or rotate in place; during the process of rotating in place, the lower end of the suction cup 4 slides on the photovoltaic panel.

[0048] When the robot needs to move forward or backward continuously, the valve core of the solenoid valve 6 switches positions to connect the air inlet of the air pump 7 with the lifting pipe 41. The air pump 7 inputs the air inhaled from the third port into the inside of the suction cup 4 through the air inlet. Compared with the suction cup 4 inhaling air inside through natural pressure difference, the suction cup 4 can quickly separate from the photovoltaic panel, accelerating the reaction time.

[0049] Then, the pushing and pulling device 2 pushes the sliding groove plate 3 to move back to its original position, so that the bearing 52 returns to the high part 301 under the pressure of the sliding groove 31 again. At this time, the lower end of the suction cup 4 disengages from the contact with the surface of the photovoltaic panel, avoiding increasing the resistance due to friction with the photovoltaic panel during the movement of the robot.

[0050] The above has described the present utility model by way of example, but the present utility model is not limited to the above specific embodiments. Any modification or variation based on the present utility model falls within the scope of protection required by the present utility model.
