Description

Technical Field

[0001] This invention relates to the field of photovoltaic cleaning technology, specifically to a solar photovoltaic cleaning robot transport vehicle. Background Technology

[0002] A prior art patent, CN116654549A, discloses a transfer system for a photovoltaic cleaning robot. The system includes a track and a transfer vehicle that can move on the track. The transfer vehicle comprises: a base frame mounted on the track; a docking frame placed at an angle on the base frame, forming an upper end and a lower end with a height difference; and a lifting device configured to adjust the height of the upper and lower ends of the docking frame respectively. The base frame has a support frame protruding towards the upper end of the docking frame. The lifting device includes an upper lifting device for adjusting the height of the upper end of the docking frame, located between the support frame and the upper end of the docking frame. The upper lifting device is inclined towards the lower end of the docking frame relative to the vertical direction in the direction extending from the support frame to the docking frame. This transfer system for the photovoltaic cleaning robot facilitates angle and height adjustment and stable load-bearing of the robot.

[0003] However, the aforementioned device still has some obvious shortcomings in its use: although the device can adjust the angle, it is only used as a transfer platform for the photovoltaic cleaning robot during the transfer process, and its effect is relatively simple. For the photovoltaic cleaning robot, the roller brush set below it often has a lot of dust attached to it after cleaning the photovoltaic panels. If the dust particles are not cleaned, it will affect the subsequent cleaning effect. At the same time, the attached particulate dust may also damage the surface of the photovoltaic panel during the rotation of the roller brush, thereby affecting the light energy conversion efficiency of the photovoltaic panel. Summary of the Invention

[0004] The purpose of this invention is to provide a solar photovoltaic cleaning robot transport vehicle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A solar photovoltaic cleaning robot transport vehicle includes: The guide rails are laid in a pair in parallel, and each guide rail has a track groove inside. The vehicle body includes a frame and four sets of track wheels. The track wheels rotate under the drive of a drive motor. The four sets of track wheels are arranged in pairs in the track grooves opened on the same side guide rail. The track wheels are fixedly connected to the frame. A pair of short-axis hydraulic telescopic cylinders and a long-axis hydraulic telescopic cylinder are fixedly installed on the top of the frame. The telescopic arms of the short-axis hydraulic telescopic cylinders and the long-axis hydraulic telescopic cylinders are connected to an inclined frame. A transfer platform is fixedly installed on the inclined frame. The transfer platform, whose height and tilt angle are adjusted by the extension and retraction of the short-axis and long-axis hydraulic telescopic cylinders, is used to receive the photovoltaic cleaning robot removed from the photovoltaic panels. The transfer platform is equipped with a dust cleaning chamber and a spray cleaning chamber. The bottom of the dust cleaning chamber is equipped with a dust blocking conveyor belt, and an exhaust pump is installed below the dust blocking conveyor belt. The exhaust pump draws air into the dust cleaning chamber, thereby adsorbing the dust on the cleaning roller of the photovoltaic cleaning robot onto the dust blocking conveyor belt. During the cyclic conveying process, the dust attached to the dust blocking conveyor belt is desorbed by the dust collection hood below. The bottom of the spray cleaning chamber is equipped with spray heads arranged linearly at equal intervals. The spray heads are connected to a water pump through spray pipes, and the water pump is connected to a cleaning tank through pipes. The water pump pumps the cleaning liquid upward through the spray heads. The upper surface of the spray cleaning chamber is also provided with a sealing groove, and a telescopic airbag is installed in the sealing groove. When spray cleaning is performed, the telescopic airbag expands and presses against the bottom of the photovoltaic cleaning robot to prevent the cleaning liquid from spraying outward.

[0006] Preferably, both the short-axis hydraulic telescopic cylinder and the long-axis hydraulic telescopic cylinder have a rotating shaft frame movably mounted on their telescopic arms. The rotating shaft frame of the short-axis hydraulic telescopic cylinder is fixedly mounted on the bottom of the inclined frame, and the rotating shaft frame of the long-axis hydraulic telescopic cylinder is movably connected to the pulley groove opened in the inclined frame via pulleys.

[0007] Preferably, the dust-blocking conveyor belt has drive rollers fixed at both ends and rotated. The drive rollers rotate under the drive of the drive motor, thereby driving the dust-blocking conveyor belt to move. The transfer platform is located at the bottom of the dust cleaning chamber and has a filter groove that runs vertically through it. The upper part of the dust-blocking conveyor belt is located in the filter groove. The dust cleaning chamber below the filter groove is also equipped with support plates at intervals to support the upper dust-blocking conveyor belt.

[0008] Preferably, a gas collecting baffle is fixedly installed below the support plate, and an upper adsorption groove is opened on one side of the gas collecting baffle. A dust collection hood is installed below the upper adsorption groove, and the gap between the upper adsorption groove and the dust collection hood is used for the belt body below the dust blocking conveyor belt to pass through. The exhaust pump is connected to the dust collection hood through a corrugated pipe. During the process of the exhaust pump drawing air outward, the belt body above the dust blocking conveyor belt adsorbs and captures the dust on the cleaning roller shaft of the photovoltaic cleaning robot. When the belt body below the dust blocking conveyor belt passes above the dust collection hood, the downward airflow causes the dust attached to the dust blocking conveyor belt to detach and enter the dust collection hood.

[0009] Preferably, the dust cleaning chamber is provided with grooves on both sides along its length. A lead screw is rotatably installed in the groove, and the lead screw is threadedly engaged with an internally threaded slider. Several separate dust scraping blades are fixed between the internally threaded sliders on both sides. The lead screw rotates under the drive of the dust scraping motor, thereby driving the dust scraping blades to reciprocate and slide. The dust is dislodged through the contact between the dust scraping blades and the cleaning roller shaft of the photovoltaic cleaning robot.

[0010] Preferably, the sealing groove is connected to a bidirectional air pump fixedly installed at the bottom of the transfer platform, and the inflation and deflation of the airbag is caused by the bidirectional air pump filling the sealing groove.

[0011] Preferably, the spray cleaning chamber has a wastewater outlet hole on the transfer platform near the short-axis hydraulic telescopic cylinder.

[0012] Preferably, the bottom of the dust collection hood is magnetically attached with a detachable cleaning plate, which allows the dust inside the dust collection hood to be discharged outwards by removing the detachable cleaning plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention not only serves as a transfer device for photovoltaic cleaning robots, but also performs dust removal and cleaning operations on the robot's cleaning rollers during the transfer process. By combining dust removal and spraying, the cleaning rollers can be effectively cleaned, thereby ensuring the cleaning effect of the photovoltaic robot, reducing the burden of manual cleaning, and reducing wear on the surface of the photovoltaic panels.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4 The present invention provides a technical solution: Example 1: A solar photovoltaic cleaning robot transport vehicle includes: Guide rail 1, a pair of guide rails 1 are laid in parallel, and each guide rail 1 has a track groove 2 inside; The vehicle body includes a frame 3 and four sets of track wheels 4. The track wheels 4 rotate under the drive of the drive motor. The four sets of track wheels 4 are arranged in pairs in the track grooves 2 opened on the same side guide rail 1. The track wheels 4 are fixedly connected to the frame 3. A pair of short-axis hydraulic telescopic cylinders 5 and long-axis hydraulic telescopic cylinders 6 are fixedly installed on the top of the frame 3. The telescopic arms of the short-axis hydraulic telescopic cylinders 5 and long-axis hydraulic telescopic cylinders 6 are connected to the tilting frame 7. A transfer table 8 is fixedly installed on the tilting frame 7. The transfer platform 8, with its height and tilt angle adjusted by the extension and retraction of the short-axis hydraulic telescopic cylinder 5 and the long-axis hydraulic telescopic cylinder 6, is used to receive the photovoltaic cleaning robot removed from the photovoltaic panels. The transfer platform 8 is equipped with a dust cleaning chamber 9 and a spray cleaning chamber 10. The bottom of the dust cleaning chamber 9 is equipped with a dust blocking conveyor belt 11, and an exhaust pump 12 is installed below the dust blocking conveyor belt 11. The exhaust pump 12 draws air into the dust cleaning chamber 9, thereby causing the dust on the cleaning roller of the photovoltaic cleaning robot to be adsorbed onto the dust blocking conveyor belt 11. During the cyclic conveying process, the dust blocking conveyor belt 11 desorbs the dust adhering to the dust blocking conveyor belt 11 through the dust collection hood 13 below. Spray cleaning chamber 10 has spray heads 14 arranged linearly at equal intervals at its bottom. The spray heads 14 are connected to water pump 15 through spray pipes. The water pump is connected to the cleaning tank through pipes. Thus, the water pump 15 pumps the cleaning liquid upward through the spray heads 14. The upper surface of the spray cleaning chamber 10 is also provided with a sealing groove 16. A telescopic airbag 17 is provided in the sealing groove 16. When spray cleaning is performed, the telescopic airbag 17 expands and abuts against the bottom of the photovoltaic cleaning robot, thereby preventing the cleaning liquid from spraying outward.

[0018] In this embodiment, the guide rail 1 is laid on the ground of the photovoltaic power station, and the vehicle body is guided by the track groove 2 opened on it. The vehicle body includes a frame 3 and four sets of track wheels 4. The track wheels 4 rotate under the drive of the drive motor. Since this drive method is common in the prior art, it will not be described in detail here. A pair of short-axis hydraulic telescopic cylinders 5 and a pair of long-axis hydraulic telescopic cylinders 6 are fixedly installed on the top of the frame 3. The combination of the short-axis hydraulic telescopic cylinders 5 and the long-axis hydraulic telescopic cylinders 6 makes the tilting frame 7 form a certain tilt angle. This setting is to adapt to the photovoltaic panels. The tilt angle is adjusted to facilitate the seamless transition between the photovoltaic cleaning robot and the transfer platform 8. However, the tilt angle of photovoltaic panels within the same photovoltaic power station varies depending on the terrain. Therefore, to ensure the transfer platform 8 can adapt to all photovoltaic rows within the same photovoltaic power station, the height and tilt angle need to be adjusted using short-axis hydraulic telescopic cylinders 5 and 6. These cylinders employ an electric hydraulic telescopic cylinder structure, enabling automatic lifting and lowering movements. The tilting frame 7 is also equipped with a visual positioning mechanism to adjust according to the tilt angle of the photovoltaic panels. Simultaneously, the tilt data of each photovoltaic row can be pre-entered into the MCU control device installed on the vehicle body, allowing for automatic adjustment of height and tilt angle according to the program. Unlike existing technologies, the transfer platform 8 in this embodiment has a dust cleaning chamber 9 and a spray cleaning chamber 10. The dust cleaning chamber 9 has a dust-blocking conveyor belt 11 at its bottom. This dust-blocking conveyor belt 11 has a fiber structure with fine pores on its surface, allowing dust to be removed through the air extraction process. The dust is adsorbed onto the dust-blocking conveyor belt 11, which is in a cyclic conveying state during the cleaning process, thus continuously adsorbing dust. The dust can also be collected by the dust collection hood 13, thereby ensuring the normal operation of the dust removal components. On the other side, a spray cleaning chamber 10 is also provided, which sprays and cleans the tightly attached dust, thereby further ensuring the cleanliness of the cleaning roller of the photovoltaic cleaning robot, thereby improving the cleaning effect of the photovoltaic row and reducing the wear caused by particulate matter on the surface of the photovoltaic panel.

[0019] Example 2: Both the short-axis hydraulic telescopic cylinder 5 and the long-axis hydraulic telescopic cylinder 6 have a rotating shaft frame 18 movably mounted on their telescopic arms. The rotating shaft frame 18 of the short-axis hydraulic telescopic cylinder 5 is fixedly mounted on the bottom of the tilting frame 7, while the rotating shaft frame 18 of the long-axis hydraulic telescopic cylinder 6 is movably connected to the pulley groove opened in the tilting frame 7 via pulleys.

[0020] In this embodiment, the specific installation method of the short-axis hydraulic telescopic cylinder 5 and the long-axis hydraulic telescopic cylinder 6 is further disclosed. The rotating shaft frame 18 of the short-axis hydraulic telescopic cylinder 5 is fixedly connected to the tilting frame 7, while the rotating shaft frame 18 of the long-axis hydraulic telescopic cylinder 6 is movably connected to the tilting frame 7, so that the tilting frame 7 can be smoothly adjusted in angle.

[0021] Example 3: The dust-blocking conveyor belt 11 has drive rollers 20 fixed at both ends. The drive rollers 20 rotate under the drive of the drive motor, thereby driving the dust-blocking conveyor belt 11 to move. The transfer table 8 is located at the bottom of the dust cleaning chamber 9 and has a filter groove that runs through it from top to bottom. The upper belt of the dust-blocking conveyor belt 11 is located in the filter groove. The dust cleaning chamber 9 below the filter groove is also equipped with support plates 21 at intervals, which support the belt of the upper dust-blocking conveyor belt 11.

[0022] Below the support plate 21, a gas collecting baffle 22 is fixedly installed separately. An upper adsorption groove 23 is provided on one side of the gas collecting baffle 22. A dust collection hood 13 is installed separately below the upper adsorption groove 23. The gap between the upper adsorption groove 23 and the dust collection hood 13 is used for the belt body below the dust blocking conveyor belt 11 to pass through. The exhaust pump 12 is connected to the dust collection hood 13 through the corrugated pipe 24. During the process of the exhaust pump 12 drawing air outward, the belt body above the dust blocking conveyor belt 11 adsorbs and captures the dust on the cleaning roller shaft of the photovoltaic cleaning robot. When the belt body below the dust blocking conveyor belt 11 passes above the dust collection hood 13, the downward airflow causes the dust attached to the dust blocking conveyor belt 11 to detach and enter the dust collection hood 13.

[0023] In this embodiment, the dust-blocking conveyor belt 11 is disposed in the filter groove opened at the bottom of the dust cleaning chamber 9. In order to prevent the dust-blocking conveyor belt 11 from deforming downward during the exhaust process, the dust cleaning chamber 9 below the filter groove is also equipped with support plates 21 at intervals to support the dust-blocking conveyor belt 11. At the same time, a gas collecting baffle 22 is fixedly installed below the support plate 21. The gas collecting baffle 22 is set to ensure that the gas flows in a directional manner. Therefore, an upper adsorption groove 23 is opened on one side of the gas collecting baffle 22. The airflow passes through the filter groove from top to bottom. During this process, the dust can be adsorbed on the upper surface of the dust-blocking conveyor belt 11. After the gas passes through the filter groove, due to the obstruction of the gas collecting baffle 22, the gas enters the dust collection hood 13 downward through the upper adsorption groove 23 on one side of the gas collecting baffle 22. The significance of this design is that the airflow generated by the exhaust pump 12 is used for both dust adsorption and desorption, thus completing multiple functions with one pump.

[0024] Example 4: The dust cleaning chamber 9 has grooves 25 on both sides along its length. Screws 26 are rotatably mounted on a fixed axis in the grooves 25. The screws 26 are threadedly engaged with internal threaded sliders 27. Several separate dust scrapers 28 are fixed between the internal threaded sliders 27 on both sides. The screws 26 rotate under the drive of the dust scraper motor, which in turn drives the dust scrapers 28 to reciprocate and slide. The dust is dislodged by the contact between the dust scrapers 28 and the cleaning roller shaft of the photovoltaic cleaning robot.

[0025] In this embodiment, in order to ensure the cleaning effect of the cleaning roller of the photovoltaic cleaning robot, the dust scraper 28 is contacted by the sliding and translational scraper 28, and the dust attached to the roller is better separated as the roller shaft of the photovoltaic robot rotates. The sliding and translational mechanism used is a common mechanism in the prior art, and will not be described in detail here.

[0026] Example 5: The sealing groove 16 is connected to the bidirectional air pump 29 fixedly installed at the bottom of the transfer table 8. The inflation and deflation of the air pump 29 into the sealing groove 16 causes the telescopic airbag 17 to expand or contract.

[0027] In this embodiment, the telescopic airbag 17 expands or contracts accordingly by the pumping or evacuating operation of the bidirectional air pump 29. Since the cleaning medium needs to be pumped outward during the cleaning process of the spray head 14 in the spray cleaning chamber 10, the bottom of the photovoltaic cleaning robot needs to be expanded and sealed by the telescopic airbag 17 in order to prevent the cleaning medium from being sprayed outward, thereby preventing the overflow of cleaning water during the spray cleaning process.

[0028] It should be noted that the electrical components mentioned in the above embodiments, such as the drive motor, exhaust pump, dust blocking conveyor belt 11, bidirectional air pump 29, and dust scraper motor, are all electrically connected to the PLC controller installed on the vehicle body through wiring. The PLC controller sends working instructions to the above electrical components at different stages to ensure the effective implementation of dust removal and spray cleaning steps.

[0029] Example 6: Wastewater outlet 30 is provided on the transfer platform 8 on the side of the spray cleaning chamber 10 near the short shaft hydraulic telescopic cylinder 5.

[0030] The bottom of the dust collection hood 13 is magnetically attached with a removable cleaning plate 31, which allows the dust inside the dust collection hood 13 to be discharged outward by removing the removable cleaning plate 31.

[0031] In this embodiment, the wastewater generated during the spray washing process flows out through the wastewater outlet 30 below the spray cleaning chamber 10. The dust that is desorbed and enters the dust collection hood 13 during the dust removal process is cleaned by opening the detachable cleaning plate 31. The detachable cleaning plate 31 is connected to the dust collection hood 13 by magnetic attraction, and this assembly method is simple and easy to operate.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
