Technical Field

[0001] This application relates to the field of photovoltaic panel cleaning equipment technology, specifically a power supply box for a photovoltaic panel cleaning robot that is easy to install. Background Technology

[0002] The power supply box of the photovoltaic panel cleaning robot is the device that provides it with power. It usually contains a battery pack or related power conversion device to ensure that the cleaning robot has sufficient power support when performing cleaning tasks on the surface of the photovoltaic panel.

[0003] Currently, the power supply box on photovoltaic panel cleaning robots is generally fixed and installed using multiple sets of bolts. This installation method is relatively sturdy, but it also has obvious drawbacks. The cumbersome installation and disassembly process makes the maintenance of the power supply box more difficult, and it requires the use of tools such as screwdrivers for disassembly and assembly, which limits the flexibility of the equipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art by proposing a photovoltaic panel cleaning robot power supply box that is easy to install, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a power supply box for a photovoltaic panel cleaning robot that is easy to install. The box includes a machine housing, with a power supply unit movably inserted into the inner side of the housing. A limit rod is fixedly connected to the bottom of the power supply unit, and an insertion hole is provided on the outer surface of the limit rod. A rotating shaft is rotatably connected to the inner side of the machine housing via a drive mechanism. A hook is fixedly sleeved on the outer surface of the rotating shaft. An upper top assembly is provided at the bottom inner side of the machine housing. A locking mechanism is provided on the machine housing to limit the rotation of the rotating shaft.

[0006] Preferably, the drive mechanism includes a support plate fixedly connected inside the machine housing, an airbag is provided on the support plate, a connecting pipe is fixedly connected to the bottom of the airbag, and an inflatable balloon is fixedly connected to the bottom end of the connecting pipe. The drive mechanism can drive the claw to insert it into the socket during the process of inserting the power supply box into the machine housing, thereby initially limiting its position.

[0007] Preferably, a fixed shaft is fixedly connected inside the machine housing, and a swing arm claw is rotatably connected to the outer surface of the fixed shaft, with both the top and bottom of the swing arm claw having an annular design.

[0009] Preferably, the upper lifting assembly includes a bottom shaft fixedly connected to the bottom of the inner side of the machine housing, and the outer surface of the bottom shaft is slidably connected to the inner surface of the fly-shaped plate. An upper lifting spring is movably sleeved on the outer surface of the bottom shaft. Under certain conditions (when the locking mechanism no longer limits the rotating shaft), the power supply box can be pushed up a certain distance so as to remove it.

[0010] Preferably, the locking mechanism includes a ratchet fixedly connected to one end of the rotating shaft. The outer surface of the machine housing is respectively provided with a first connecting shaft and a second connecting shaft.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-6 A power supply box for a photovoltaic panel cleaning robot that is easy to install includes a machine shell 1, a power supply box 2 that is movably inserted into the inner side of the machine shell 1, a limit rod 3 that is fixedly connected to the bottom of the power supply box 2, an insertion hole 4 that is opened on the outer surface of the limit rod 3, a rotating shaft 5 that is rotatably connected to the inner side of the machine shell 1 through a drive mechanism, a hook 6 that is fixedly sleeved on the outer surface of the rotating shaft 5, an upper top assembly that is provided at the bottom of the inner side of the machine shell 1, and a locking mechanism that is provided on the machine shell 1 for limiting the rotating shaft 5 after rotation.

[0023] With the above technical solution, when installing the power supply box 2 of the photovoltaic panel cleaning robot, simply insert the power supply box 2 into the machine shell 1. At this time, the two sets of limiting rods 3 at the bottom of the power supply box 2 will slide down along the inner side of the machine shell 1. During this process, the rotating shaft 5 can be driven to rotate through the drive mechanism until the hook 6 is inserted into the insertion hole 4 opened on the surface of the limiting rod 3. With the help of the locking mechanism, it can be made to be in a stable state, and the power supply box 2 can be easily installed without the aid of any tools.

[0024] Specifically, the drive mechanism includes a support plate 7 fixedly connected inside the machine housing 1. An airbag 8 is provided on the support plate 7. A connecting pipe 9 is fixedly connected to the bottom of the airbag 8. The upper end of the connecting pipe 9 passes through the support plate 7, and an inflatable balloon 10 is fixedly connected to the bottom end of the connecting pipe 9.

[0025] With the above technical solution, both the airbag 8 and the inflatable balloon 10 are made of rubber. They expand when inflated and contract when deflated and expelled. In the initial state (when the power supply box 2 is not installed), they are normally inflated.

[0026] Specifically, a fixed shaft 11 is fixedly connected inside the machine housing 1, and a swing arm claw 12 is rotatably connected to the outer surface of the fixed shaft 11, with the top and bottom of the swing arm claw 12 being annular designs.

[0027] Through the above technical solution, the ring design at both ends of the swing arm claw 12 is to facilitate contact with the upper inflatable balloon 10 relatively smoothly, and to allow for smooth sliding along the wings of the flight plate 15.

[0028] Specifically, inside the machine housing 1, from top to bottom, there are upper fixed blocks 13 and lower fixed blocks 14. The inner sides of the upper fixed blocks 13 and lower fixed blocks 14 are slidably connected to the fly-shaped plate 15. The outer surface of the fly-shaped plate 15 is fixedly connected to the rack 16. The outer surface of the rotating shaft 5 is fixedly sleeved with a gear 17, and the outer surface of the gear 17 is meshed with the outer surface of the rack 16.

[0029] Through the above technical solution, the flying wing layout of the flying plate 15 is designed to make smooth contact with the bottom of the swing arm claw 12 during its up and down movement, while the ring design at the top is designed to make smooth contact with the inflatable balloon 10, squeezing the inflatable balloon 10 or pushing the flying plate 15 after the inflatable balloon 10 expands.

[0030] Specifically, the top assembly includes a bottom shaft 18 fixedly connected to the bottom of the inner side of the machine housing 1, and the outer surface of the bottom shaft 18 is slidably connected to the inner surface of the fly-shaped plate 15. The outer surface of the bottom shaft 18 is movably sleeved with a top spring 19.

[0031] Through the above technical solution, as the flying plate 15 slides down along the inner side of the upper fixed block 13 and the lower fixed block 14, the inner surface of the flying plate 15 will slide along the bottom shaft 18 (the bottom shaft 18 gradually enters the flying plate 15), during which the upper top spring 19 is compressed and deformed.

[0032] Specifically, the locking mechanism includes a ratchet 20 fixedly connected to one end of the rotating shaft 5. The ratchet 20 is located on the outside of the machine housing 1. The outer surface of the machine housing 1 is respectively provided with a first connecting shaft 21 and a second connecting shaft 23. The outer surface of the first connecting shaft 21 is rotatably connected with a pawl 22, and the second connecting shaft 23 is provided with a spring pawl 24.

[0033] With the above technical solution, under the elastic limiting action of the spring pawl 24, the tip of the pawl 22 will be stuck between the teeth of the ratchet 20, so that the ratchet 20 can only rotate in one direction and cannot reverse.

[0034] Working Principle: During installation, the power supply box 2 of this photovoltaic panel cleaning robot is simply inserted into the machine casing 1 (pressing down firmly). At this time, the two sets of limiting rods 3 at the bottom of the power supply box 2 will slide down along the inner side of the machine casing 1, and the bottom of the power supply box 2 will gradually compress the airbag 8. During the compression of the airbag 8, the airflow inside is forced through the connecting pipe 9 into the expansion bladder 10. The expansion bladder 10 will gradually expand, and as its volume increases, it will touch the tops of the two sets of swing arm claws 12, causing them to gradually expand outwards. That is, the swing arm claws 12 will rotate around the fixed axis 11. As the tops of the two sets of swing arm claws 12 move away from each other, their bottoms will slide along the wing surface of the flying plate 15, impacting the flying plate. 15 slides into position, and with the expansion balloon 10 pushing down on the top of the fly-shaped plate 15, the entire fly-shaped plate 15 gradually slides down along the inner side of the upper fixed block 13 and the lower fixed block 14. At the same time, the rack 16 on the surface of the fly-shaped plate 15 moves down, which drives the gear 17 meshing with it to rotate, thereby driving the rotating shaft 5 to rotate until the bottom of the power supply box 2 contacts the top of the machine housing 1. At the same time, the tip of the hook 6 just gets into the socket 4, thereby stabilizing and limiting the limit rod 3. At this time, the ratchet 20 will rotate synchronously with the rotation of the rotating shaft 5. During this period, the ratchet 20 will move the pawl 22, so that the tip of the pawl 22 passes through different teeth of the ratchet 20 in sequence under the elastic limiting action of the spring pawl 24, until the rotating shaft 5 rotates to the appropriate position. (The pawl 6 engages with the insertion hole 4). At this time, the locking mechanism will stabilize and limit the rotating shaft 5 to prevent the pawl 6 from deflecting. Simultaneously, as the flyboard 15 moves downward, it will slide down along the bottom shaft 18 and compress the upper spring 19. After the locking mechanism limits the rotating shaft 5, the entire power supply box 2 will remain in a relatively stable state, meaning that the power supply box 2 can be easily installed without any tools (simply insert the power supply box 2 into the machine housing 1). When disassembling, simply manually push down the protruding lever on the pawl 22 so that the pawl 22 abuts against the spring lever 24 and is no longer stuck between the teeth of the ratchet 20. At this time, under the elastic reset action of the upper spring 19, the flyboard 15 will move upward, thereby passing through the teeth. Strip 16 drives the rotating shaft 5 to rotate in the opposite direction, causing the hook 6 to disengage from the insertion hole 4. During this process, the flying plate 15 will abut against the bottom end of the swing arm claw 12. As the swing arm claw 12 rotates around the fixed shaft 11, the bottom end of the swing arm claw 12 will slide along the surface of the flying plate 15 (the bottom ends of the swing arm claw 12 move away from each other), and the top ends of the swing arm claw 12 will move closer to each other. Combined with the upward push and compression of the expansion balloon 10 by the top of the flying plate 15, the expansion balloon 10 is gradually compressed. The airflow inside it will re-enter the airbag 8 through the connecting pipe 9, thereby causing the airbag 8 to deform and expand again (return to its original shape). Finally, by using the expansion of the airbag 8 to push upward, the power supply box 2 and the limit rod 3 are pushed upward a certain distance, and the power supply box 2 can be easily removed for quick and convenient maintenance.
