Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel cleaning, and in particular to a distributed photovoltaic panel cleaning robot with an air drying function. Background Art

[0002] Distributed photovoltaic panels, also known as solar panels, are devices that use photovoltaic technology to directly convert solar radiation into electrical energy. Existing distributed photovoltaic panels are mostly placed side by side, with horizontal and tilted placement angles. Since photovoltaic panels are exposed to the external environment for a long time, dust and other foreign matter are easily accumulated on their surfaces. In order to ensure their photoelectric conversion efficiency, photovoltaic panels need to be cleaned regularly; The existing photovoltaic panel cleaning methods are divided into two types: manual and mechanical. Mechanical cleaning is mostly achieved by robots. When the robot cleans the horizontally placed photovoltaic panel, the cleaning liquid sprayed on the surface of the photovoltaic panel by the robot will temporarily remain on the surface of the photovoltaic panel, which can play a certain role in soaking and disintegrating foreign matter with strong adhesion on the surface of the photovoltaic panel, providing convenience for the cleaning of the photovoltaic panel. However, for the photovoltaic panel placed tilted, the cleaning liquid sprayed on the surface of the photovoltaic panel will quickly flow along the photovoltaic panel, resulting in the cleaning liquid being unable to fully contact with the foreign matter on the surface of the photovoltaic panel, making it difficult to clean the foreign matter with strong adhesion on the surface of the photovoltaic panel, increasing the difficulty of cleaning; In addition, existing distributed photovoltaic panels are generally arranged in multiple rows. When the robot completes the cleaning operation of a row of photovoltaic panels, staff are often required to manually transfer them to the next row of photovoltaic panels, which increases the workload of staff and reduces the cleaning efficiency of photovoltaic panels. Therefore, a distributed photovoltaic panel cleaning robot with an air drying function is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 8A distributed photovoltaic panel cleaning robot with an air drying function comprises a mobile shell 1 and a walking mechanism. A cleaning box 2 is fixedly connected to the top of the mobile shell 1. Furthermore, a water storage chamber 201 and a drying chamber 202 are arranged inside the cleaning box 2. An air pump 8 and a water pump 7 connected to the connecting pipe 6 are installed at the top of the connecting pipe 6. One end of the air pump 8 is connected to the drying chamber 202 through an air pipe, and one end of the water pump 7 is connected to the water storage chamber 201 through a water diversion pipe.

[0020] It should be noted that: the water storage chamber 201 is filled with cleaning liquid, and the water pump 7 can extract the cleaning liquid in the water storage chamber 201, and finally spray it on the surface of the photovoltaic panel through the rotating tube 16; an electric heating rod is arranged inside the drying chamber 202, and the electric heating rod can heat the air inside the drying chamber 202, and then it is extracted under the action of the air pump 8 and sprayed out through the rotating tube 16, so that the cleaned photovoltaic panel can be air-dried.

[0021] The inner wall of the mobile housing 1 is fixedly connected with a fixed mounting plate 5, and a piston plate 11 is slidably arranged on the inner side of the mobile housing 1 below the fixed mounting plate 5. Two symmetrically arranged lifting cylinders 9 are installed on the top of the fixed mounting plate 5, and the telescopic ends of the lifting cylinders 9 are fixedly connected to the top of the piston plate 11. A connecting pipe 6 is fixedly connected to the top of the fixed mounting plate 5, and a plurality of telescopic hoses 10 connected to the connecting pipe 6 are fixedly connected to the bottom of the fixed mounting plate 5 (the arrangement of the telescopic hoses 10 allows the connection between the rotating tube 16 and the connecting pipe 6 to be maintained when the piston plate 11 is raised or lowered), and a plurality of adapter holes penetrating the piston plate 11 are provided on the top of the piston plate 11, and the internal rotation connection of the adapter holes There is a rotating tube 16, the top of the rotating tube 16 is fixedly connected to a gear plate 14 (adjacent gear plates 14 are meshed with each other), a circular opening connected to the rotating tube 16 is opened at the center of the gear plate 14, a turntable 17 is fixedly connected to the bottom end of the rotating tube 16, a cleaning cotton 18 is fixedly connected to the bottom end of the turntable 17, a water outlet connected to the rotating tube 16 is opened at the center of the turntable 17 and the cleaning cotton 18, a solenoid valve 21 is arranged inside the rotating tube 16, one end of the telescopic hose 10 is rotatably connected to the circular opening at the center of the gear plate 14, a rotating motor 12 is installed at the top of the piston plate 11, and a driving gear 13 meshed with the gear plate 14 is fixedly connected to the output end of the rotating motor 12.

[0022] It should be noted that: the rotating motor 12 is used to drive the driving gear 13 to rotate, and the driving gear 13 drives one of the gear plates 14 to rotate. Under the meshing action between adjacent gear plates 14, the gear plates 14 at all locations rotate at the same time, and then the rotating tube 16 at the bottom end rotates, and the rotating tube 16 drives the turntable 17 to rotate, and the turntable 17 drives the cleaning cotton 18 at the bottom end to rotate. At the same time, the lifting cylinder 9 is used to drive the piston plate 11 to move downward, and then drive the cleaning cotton 18 to move downward, so that the cleaning cotton 18 contacts the surface of the photovoltaic panel, which can clean the dirt on the surface of the photovoltaic panel.

[0023] It is worth noting that the setting of the solenoid valve 21 can control the opening and closing of the rotating tube 16. When the rotating tube 16 is closed, the upward movement of the piston plate 11 will cause negative pressure to be generated inside the sealing frame 19 (similar to the principle of generating negative pressure inside the piston cylinder by pulling the piston block), so that the sealing frame 19 can be adsorbed on the surface of the photovoltaic panel, and then the robot can be adsorbed on the surface of the photovoltaic panel.

[0024] A magnetic plate 20 is slidably arranged inside the movable housing 1, and a sealing frame 19 is fixedly connected to the bottom end of the magnetic plate 20, and the top end of the sealing frame 19 is connected to the piston plate 11 through a pressure spring 30; further, an electromagnet 15 magnetically attracted to the magnetic plate 20 is installed at the bottom end of the piston plate 11, and a rubber layer for enhancing the sealing is arranged at the bottom end of the sealing frame 19.

[0025] It should be noted that the electromagnet 15 can magnetically move the magnetic plate 20 upward, and the magnetic plate 20 drives the sealing frame 19 upward and compresses the pressure spring 30. At this time, the sealing frame 19 is not in contact with the surface of the photovoltaic panel. After the electromagnet 15 is powered off, the electromagnet 15 loses its magnetism and no longer magnetically attracts the magnetic plate 20. Under the elastic force of the pressure spring 30, the magnetic plate 20 moves downward, and the magnetic plate 20 drives the sealing frame 19 downward, so that the bottom end of the sealing frame 19 is in close contact with the surface of the photovoltaic panel, which can limit the flow of the cleaning liquid sprayed on the photovoltaic panel, prolong the contact time between the cleaning liquid and the dirt on the surface of the photovoltaic panel, so that the cleaning liquid can soak and disintegrate the dirt, thereby facilitating the cleaning of adhesive dirt.

[0026] It is worth noting that the rubber layer can enhance the sealing between the bottom end of the sealing frame 19 and the photovoltaic panel.

[0027] The walking mechanism includes a connecting head 28 fixedly connected to one end of the moving shell 1 and a moving frame 4 symmetrically arranged on both sides of the connecting head 28, an adapter block 22 is slidably arranged on the inner side of the moving frame 4, and a guide groove 2201 is opened at one end of the adapter block 22, and the two side surfaces of the moving shell 1 are fixedly connected with driving tooth plates 3 that are slidably connected to the guide groove 2201, and the two ends of the driving tooth plate 3 are fixedly connected with limit plates 29 (the setting of the limit plates 29 can prevent the driving tooth plate 3 from being separated from the guide groove 2201), and the side wall of the moving frame 4 is fixedly connected with a support plate, and a walking motor 23 is installed at the bottom end of the support plate, and the output end of the walking motor 23 is connected to a walking wheel 24.

[0028] It should be noted that: the walking motor 23 drives the walking wheel 24 at its output end to rotate. The surface of the walking wheel 24 is provided with anti-slip grooves, which can enhance the friction between the walking wheel 24 and the side wall of the photovoltaic panel. The walking wheel 24 is used to roll along the side wall of the photovoltaic panel, thereby driving the moving frames 4 on both sides to move. The moving frame 4 drives the moving shell 1 to move, and then drives the entire robot to move, thereby realizing the cleaning function of all photovoltaic panels in a row.

[0029] Furthermore, an installation cavity 2202 connected to the guide groove 2201 is provided inside the adapter block 22, a transfer motor 26 is installed inside the installation cavity 2202, an output end of the transfer motor 26 is fixedly connected to a transfer gear 27 meshing with the driving gear plate 3, further, a sliding groove is provided on the inner wall of the movable frame 4, a rubber layer is provided on the inner wall of the sliding groove, and a slider slidably connected to the sliding groove is fixedly connected to the side wall of the adapter block 22.

[0030] It should be noted that: the transfer motor 26 drives the transfer gear 27 at its output end to rotate, and the transfer gear 27 drives the driving tooth plate 3 meshing therewith to move, and the driving tooth plate 3 drives the moving shell 1 to move, and then drives the entire robot to move, so that the entire robot moves obliquely upward along the inclined photovoltaic panel to make it detach from the cleaned photovoltaic panel. After the entire robot detaches from the cleaned photovoltaic panel, the entire robot is in a suspended state at this time. Since the moving frames 4 on both sides are in an inclined state, the gravity of the robot will have a component force along the direction of the moving frame 4, so that the robot drives the adapter block 22 to slide down the inside of the moving frame 4. Since a rubber layer is provided on the inner wall of the slide groove, the friction between the sliders on both sides of the adapter block 22 and the slide groove is relatively large, so that the sliding speed of the entire robot is relatively slow, ensuring that when the robot slides down to contact the next row of photovoltaic panels to be cleaned, the impact force is small, and no damage is caused to the surface of the photovoltaic panel. At the same time, the robot completes the automatic transfer function between two adjacent rows of photovoltaic panels.

[0031] Reference Figure 8It is worth noting that: when the mobile shell 1 is separated from the photovoltaic panel, the large offset of the center of gravity will cause excessive squeezing pressure between the adapter block 22 and the side wall of the mobile frame 4, which will in turn cause excessive friction, thus affecting the normal downward movement of the robot body. Therefore, a plurality of rolling grooves symmetrical about the slider are provided on both side walls of the adapter block 22, and sliding balls are arranged inside the rolling grooves for rolling. The sliding balls cooperate with the rolling grooves to convert the sliding friction between the adapter block 22 and the side wall of the mobile frame 4 into rolling friction, thereby greatly reducing the influence of the increase in squeezing pressure on the friction, thereby ensuring that the robot can normally realize the sliding function along the mobile frame 4.

[0032] Furthermore, a symmetrical rolling groove is provided at the bottom end of the movable frame 4, and a ball 25 is provided inside the rolling groove for rolling. The provision of the ball 25 facilitates the movable frame 4 to move on the surface of the photovoltaic panel.

[0033] Furthermore, a plurality of notches for water flow are provided at the bottom of the mobile housing 1 . The notches are provided to facilitate the outflow of the cleaning liquid inside the mobile housing 1 .

[0034] When the present invention is used, the staff is required to first place the entire robot on the surface of the photovoltaic panel to be cleaned (on the photovoltaic panel at the end of a row of photovoltaic panels), and at the same time make the mobile frame 4 lean against the side wall of the photovoltaic panel to be cleaned, at this time, the surface of the walking wheel 24 contacts the side wall of the photovoltaic panel to be cleaned, and the ball 25 at the bottom end of the mobile frame 4 contacts the surface of the next row of photovoltaic panels to be cleaned (a buffer cotton layer is provided on the surface of the ball 25 to prevent the ball 25 from causing damage to the photovoltaic panel during rolling); When performing the cleaning operation, the control circuit inside the robot will first cut off the power to the electromagnet 15, and under the action of the pressure spring 30, the magnetic suction plate 20 will move downward, thereby driving the sealing frame 19 to move downward, so that the bottom end of the sealing frame 19 is closely fitted with the surface of the photovoltaic panel, and then the control circuit starts the water pump 7, and the water pump 7 draws the cleaning liquid in the water storage chamber 201 inside the water tank into the connecting pipe 6, and then flows into the telescopic hose 10 and the rotating tube 16 through the connecting pipe 6, and then is sprayed out through the water outlet between the turntable 17 and the cleaning cotton 18. The sprayed cleaning liquid will gather on the surface of the photovoltaic panel under the flow limiting effect of the sealing frame 19, so that it can fully contact the dirt on the surface of the photovoltaic panel and soak some adherent dirt. After the soaking is finished, the control circuit controls the lifting cylinder 9 to work, so that the lifting cylinder 9 drives the piston plate 11 to move downward, and then drives the rotating tube 16 and the cleaning cotton 18 to move downward (in this process, the telescopic hose 10 is stretched) and contact the photovoltaic panel. At the same time, the control circuit turns on the rotating motor 12, and the rotating motor 12 drives the driving gear 13 at its output end to rotate, and the driving gear 13 drives the gear plate 14 meshing therewith to rotate. Under the meshing action between the multiple gear plates 14, the gear plates 14 at various locations rotate at the same time, and the gear plate 14 drives the rotating tube 16 to rotate, and the rotating tube 16 drives the turntable 17 at its bottom and the cleaning cotton 18 to rotate, so that the cleaning cotton 18 can realize the function of cleaning the dirt on the surface of the photovoltaic panel; After cleaning is completed, the control motor supplies power to the electromagnet 15 again, so that the magnetic suction plate 20 moves up and drives the sealing frame 19 to move up. At this time, the sewage generated by cleaning will flow away through the gap at the bottom of the movable housing 1. After that, the control circuit controls the air pump 8 to work, and at the same time controls the electric heating rod inside the drying chamber 202 to work. The electric heating rod can heat the air inside the drying chamber 202, and then it is drawn out under the action of the air pump 8 and sprayed out through the rotating tube 16, so that the cleaned photovoltaic panel can be air-dried; After the air drying is completed, the control circuit controls the travel motor 23 to work, and the travel motor 23 drives the travel wheel 24 at its output end to rotate, and the travel wheel 24 rolls along the side wall of the photovoltaic panel, thereby driving the moving frames 4 on both sides to move, and the moving frame 4 drives the moving shell 1 to move, and then drives the entire robot to move, so as to realize the cleaning function of all photovoltaic panels in a row; After cleaning a row of photovoltaic panels, the control circuit controls the transfer motor 26 to work, and the transfer motor 26 drives the transfer gear 27 at its output end to rotate, and the transfer gear 27 drives the driving tooth plate 3 meshing therewith to move, and the driving tooth plate 3 drives the moving shell 1 to move, and then drives the entire robot to move, so that the entire robot moves obliquely upward along the inclined photovoltaic panel to make it separate from the cleaned photovoltaic panel. After the entire robot separates from the cleaned photovoltaic panel, the entire robot is in a suspended state at this time. Since the moving frames 4 on both sides are in an inclined state, the gravity of the robot will have a component force along the direction of the moving frame 4, so that the robot drives the adapter block 22 to slide down the inside of the moving frame 4. Since the inner wall of the slide groove is provided with a rubber layer, the friction between the sliders on both sides of the adapter block 22 and the slide groove is relatively large, so that the sliding speed of the entire robot is relatively slow, ensuring that when the robot slides down to contact with the next row of photovoltaic panels to be cleaned, the impact force is relatively small, and no damage is caused to the surface of the photovoltaic panel. Afterwards, the control circuit first operates the lifting cylinder 9 to move the piston plate 11 downward, and then controls the electromagnet 15 to cut off the power, so that the sealing frame 19 moves downward, and finally, closes the solenoid valve 21, and then closes the rotating tube 16, and then opens the lifting cylinder 9 again to move the piston plate 11 upward, so that negative pressure is generated inside the sealing frame 19, so that the robot is adsorbed on the surface of the photovoltaic panel, and then the control circuit starts the transfer motor 26 to make the transfer motor 26 rotate in the opposite direction (compared to the rotation direction when the entire robot is driven away from the photovoltaic panel). Since the robot is adsorbed on the surface of the photovoltaic panel and cannot move, at this time, the transfer gear 27 moves along the driving gear plate 3 obliquely. It rolls upward, thereby driving the moving frame 4 to move obliquely upward. When the moving frame 4 moves to the end of the driving tooth plate 3, the moving frame 4 is in a suspended position. Under the action of gravity of the moving frame 4, it slides obliquely downward until the ball 25 at its bottom end contacts the surface of the next row of photovoltaic panels, completing the robot's automatic transfer function between two adjacent rows of photovoltaic panels. After that, the piston plate 11 moves downward, so that the negative pressure inside the sealing frame 19 disappears. At the same time, the electromagnet 15 is energized to move the sealing frame 19 upward and reset, and then the above cleaning steps are repeated. There is no need for manual transfer by the staff, which reduces the workload and improves the cleaning efficiency of the photovoltaic panels.
