Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station cleaning technology, and in particular to a photovoltaic cleaning robot cross-row transfer device with stable positioning and parking function. Background Technology

[0002] The use of solar energy as an energy source and power source has a history of over 300 years. However, with the increasing scarcity of resources such as oil and coal, developing solar energy as a urgently needed new energy source and the foundation of the future energy structure has become a pressing research topic in recent years. Solar photovoltaic panels are power generation devices that produce direct current (DC) electricity when exposed to sunlight, and they are currently widely used in various fields to provide clean and sustainable electricity.

[0003] However, photovoltaic panels are usually exposed outdoors, and over time, their surfaces inevitably become covered with dust and grime, affecting their photoelectric conversion efficiency. Therefore, photovoltaic panels need to be cleaned regularly. Currently, there are various methods for cleaning photovoltaic panels, including manual cleaning using handheld automatic cleaning equipment, but this method suffers from high labor costs.

[0004] Patent CN222395643U discloses a photovoltaic cleaning cross-row mechanism. The mechanism is driven by a drive motor that rotates the drive wheel through a transmission shaft, thereby driving the cross-row machine to move. After reaching the corresponding photovoltaic module position, the control box communicates with the photovoltaic cleaning robot and sends a signal to the robot to perform the cleaning work. After the work is completed, the robot returns to the cross-row machine's stopping position and then moves with the cross-row machine to the next row of photovoltaic modules to clean until all the covered areas are cleaned.

[0005] However, during the process of transferring the photovoltaic cleaning robot from the crossover machine to the photovoltaic module, the robot's large weight can easily cause the crossover machine's center of gravity to shift to one side, causing it to tilt towards the photovoltaic module. When the cleaning robot is completely detached and transferred to the photovoltaic module, the crossover machine's center returns to its original position, causing the entire machine to vibrate. This can easily cause the machine to deviate from its accurate alignment with the photovoltaic module, resulting in misalignment of the cleaning robot's movement track on both the crossover machine and the photovoltaic module. When it automatically moves back to the crossover machine, it may experience vibrations from going up and down steps or even become completely stuck. Therefore, improvements to the current crossover machine are urgently needed. Utility Model Content

[0006] In view of the above problems, this utility model provides a photovoltaic cleaning robot cross-row transfer device with stable positioning and parking function.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0008] A photovoltaic cleaning robot cross-row transfer device with stable positioning and parking function is provided, including a ground track fixed on the ground and a support body slidably set on the ground track. The bottom of the support body is provided with a drive component for driving the support body to move on the track, and the top of the support body is provided with a storage frame for accommodating the photovoltaic cleaning robot. The storage frame is provided with an extended track for supporting the photovoltaic cleaning robot and for the photovoltaic cleaning robot to slide.

[0009] The bottom of the support body is equipped with positioning components for positioning the support body. Several sets of positioning components are spaced apart along the sliding direction of the support body, and two parallel ground tracks are provided. The positioning components include two symmetrically arranged top plates, which are movably mounted on one side of the ground tracks. The support body is equipped with a driving component for driving the top plates to abut against the side wall of the ground tracks.

[0010] Furthermore, the driving component includes an electric push rod, a connecting rod, a drive seat, and a guide sleeve. The electric push rod is vertically fixed on the main body of the support. Both top plates are located between the two tracks of the ground track. The drive seat is fixedly connected to the output end of the electric push rod. Two sets of connecting rods and guide sleeves are symmetrically arranged. One end of the connecting rod is hinged to the top plate and the other end is hinged to the drive seat. The guide sleeve is rotatably connected to the main body of the support, and the connecting rod slides through the guide sleeve.

[0011] Furthermore, an anti-slip pad is provided on the side of the top plate away from the connecting rod.

[0012] Furthermore, the two tracks of the ground track are provided with limit grooves along their own length on the opposite sides. A limit frame is fixedly installed at the bottom of the support body, and the limit frame extends into the limit groove and is slidably connected in the limit groove.

[0013] Furthermore, a roller is horizontally arranged on the limiting frame, and the roller rolls in contact with the bottom wall of the limiting groove, with a gap of 3-5mm between the top of the roller and the top wall of the limiting groove.

[0014] Furthermore, the drive assembly includes a drive motor, and a drive wheel is coaxially connected to the output shaft of the drive motor, with the drive wheel in frictional contact with the ground track.

[0015] The beneficial effects of this utility model are as follows: After the drive component drives the support body to move to one side of the photovoltaic panel group and align with a row of photovoltaic panels, the electric push rod in the positioning component moves, driving the drive seat to move down and causing the two top plates to rub against the track, thereby limiting and fixing the support body. At the same time, under the limiting action of the limiting frame extending from the side into the ground track, the support body can also be limited at the maximum tilting angle, which greatly improves the parking stability of the support body on the ground track on the side of the photovoltaic panel group, and makes the photovoltaic cleaning robot enter and exit the storage box smoothly.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a photovoltaic cleaning robot cross-row transfer device with stable positioning and parking function, referring to... Figure 1 and Figure 2 The system includes a ground track 2 fixed to the ground and a support body 1 slidably mounted on the ground track 2. The ground track 2 is located on one side of the photovoltaic panel array, passing through the starting point on one side of each row of photovoltaic panels. The support body 1 is slidably mounted on the ground track 2 along its length. A storage frame 11 is fixedly connected to the top of the support body 1, and an extension track 12 is fixed inside the storage frame 11. The extension track 12 provides support for the photovoltaic cleaning robot and allows it to slide horizontally within the storage frame 11, which provides parking and storage space for the photovoltaic cleaning robot. When the support body 1 moves to the side of the photovoltaic panel, the extension track 12 aligns with the track on the photovoltaic panel, allowing the photovoltaic cleaning robot to automatically walk onto the photovoltaic panel.

[0021] Two parallel ground tracks 2 are provided. Support piers are fixed to the outside of the photovoltaic panel group by cement pouring. Two support piers are arranged as a group, and multiple groups are arranged at intervals along the arrangement direction of the photovoltaic panels in the photovoltaic panel group. Support sleepers are fixed between the two support piers in each group. The ground tracks 2 are fixed on the support sleepers. The two ground tracks 2 are symmetrically arranged, and the support piers are used to level the ground tracks 2.

[0022] The support body 1 is provided with a drive component for driving the support body 1 to move on the ground track 2. In this embodiment of the application, the drive component includes a drive motor 41, and a moving wheel 42 is coaxially connected to the output shaft of the drive motor 41. The moving wheel 42 is in frictional contact with the ground track 2.

[0023] A positioning component 3 is provided at the bottom of the support body 1. The positioning component 3 is used to position and fix the support assembly. Several sets of positioning components 3 are spaced apart along the sliding direction of the support body 1. Specifically, the positioning component 3 includes two symmetrically arranged top plates 31. The top plates 31 are movably disposed on one side of the ground track 2. A driving member is provided on the support body 1 to drive the top plates 31 to abut against the side wall of the ground track 2. By making the top plates 31 rub against the ground track 2, the movement of the support body 1 on the ground track 2 is restricted.

[0024] In this embodiment, the driving component can be composed of an electric push rod 32, a connecting rod 33, a drive seat 34, and a guide sleeve 35. The electric push rod 32 is vertically fixed on the support body 1, and the two top plates 31 are located between the two tracks of the ground track 2. The drive seat 34 is fixedly connected to the output end of the electric push rod 32. Two sets of connecting rods 33 and guide sleeves 35 are symmetrically arranged. One end of the connecting rod 33 is hinged to the top plate 31, and the other end is hinged to the drive seat 34. The guide sleeve 35 is rotatably connected to the support body 1, and the connecting rod 33 slides through the guide sleeve 35. When the electric push rod 32 drives the drive seat 34 to rise and fall vertically, under the guiding action of the guide sleeve 35 on the support body 1, the length of the connecting rod 33 on both sides of the guide sleeve 35 changes, so that the top plate 31 can abut against the side wall of the ground track 2 under the push of the connecting rod 33. To prevent the top plate 31 from freely flipping with the connecting rod 33 under gravity after it loses contact with the ground track 2, thus avoiding wear caused by the top plate 31 remaining in contact with the ground track 2, the top plate 31 can be damped and hinged with the connecting rod 33. This allows the top plate 31 to overcome damping and rotate to a flat position against the side wall of the ground track 2 under the force of the connecting rod 33, increasing friction. After the top plate 31 loses contact with the ground track 2, it also maintains its flipping angle relative to the connecting rod 33, preventing the top plate 31 from freely flipping under gravity.

[0025] In this embodiment, both top plates 31 are located between two ground tracks 2. An electric push rod 32 drives a drive seat 34 to rise and fall vertically. The connecting rod 33, top plates 31 and guide sleeves 35 are symmetrically arranged on both sides of the drive seat 34. The rise and fall of the drive seat 34 simultaneously drives the two top plates 31 to move, which can balance the force of the two top plates 31 supporting the ground tracks 2.

[0026] To enhance the friction between the top plate 31 and the track sidewall, in this embodiment, an anti-slip pad 36 is fixed to the side of the top plate 31 away from the connecting rod 33. The anti-slip pad 36 can be made of rubber or ceramic to increase the friction between the top plate 31 and the ground track 2.

[0027] Furthermore, limit grooves 21 are provided along the length of each of the two tracks of the ground track 2 on the side that are far apart from each other. A limit frame 13 is integrally fixedly connected to the bottom of the support body 1. The limit frame 13 extends into the limit groove 21 and slides within the limit groove 21. By cooperating with the limit frame 13 and the limit groove 21, the maximum tilting angle of the support body 1 can be limited, thereby improving the stability of the support body 1 sliding on the ground track 2.

[0028] Furthermore, rollers 14 are horizontally arranged on the limiting frame 13. The rollers 14 roll in contact with the lower bottom wall of the limiting groove 21. By utilizing the rolling contact between the rollers 14 and the lower bottom wall of the limiting groove 21, the support points of the support body 1 on the ground track 2 can be increased, thereby improving the stability of the support body 1. At the same time, the rolling of the rollers 14 within the limiting groove 21 can also reduce the friction of the support body 1 moving on the ground track 2. The top of the rollers 14 is spaced 3-5mm from the top wall of the limiting groove 21. This provides a certain amount of room for the rollers 14 to move while preventing them from getting stuck in the limiting groove 21, and controls the maximum amount of movement when the support body 1 tilts to one side, thereby reducing the lateral tilting phenomenon of the support body 1 when the photovoltaic cleaning robot moves between the housing frame and the photovoltaic panel group.
