Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a hoisting device for a support structure of a photovoltaic system in a plain. Background Technology

[0002] A photovoltaic power generation system mainly consists of three parts: solar panels (modules), controllers, and inverters. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, a photovoltaic power generation device is formed. Photovoltaic power generation does not consume fossil fuels, so it does not cause environmental pollution.

[0003] Regarding the above and existing related technologies: When installing photovoltaic power generation equipment, some photovoltaic brackets need to be installed on columns. During the installation process, lifting equipment is required to lift the photovoltaic brackets. Since traditional lifting equipment is large and most photovoltaic equipment is installed outdoors, it is easy to encounter problems such as inconvenience in handling traditional lifting equipment, which affects the installation efficiency. Therefore, to address the above problems, a lifting device for photovoltaic brackets in plains is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The utility model provides a hoisting device for a photovoltaic support structure in a plain, comprising a column, pulleys, and a support device. The pulleys are located directly above the column, and a hoisting rope is inserted into the inner surface of the pulleys. The support device is located on one side of the column and includes a base plate. The base plate is located on one side of the column, and two support wheels are rotatably connected to the inner surfaces of both sides of the base plate. A support frame is fixedly connected to the upper surface of the base plate, and a movable block is slidably connected to the surface of the support frame. The bottom end of the movable block is fixedly connected to the upper surface of the pulleys. When the base plate moves, it will drive the pulleys on the support frame and the movable block to move. Then, the photovoltaic support structure is hoisted using a hoisting rope. By setting up the base plate, support wheels, support frame, and movable block, the photovoltaic support structure can be easily hoisted, and the entire device can also be easily moved.

[0006] Preferably, a handle is fixedly connected to the side wall of the support frame, and the handle will drive the support frame to move. The support frame can be moved easily by setting the handle.

[0007] Preferably, the side wall of the support frame is fixedly connected with multiple limiting rings, and the surface of the limiting rings is rotatably connected with clamping rings. The limiting rings and clamping rings are sleeved on the surface of the column, and pushing the clamping rings causes the clamping rings to rotate to the surface of the column. By setting the limiting rings and clamping rings, the position between the support frame and the column can be restricted.

[0008] Preferably, the inner walls of the clamping ring and the fixing ring are threaded with fixing pins. After the clamping ring is attached to the fixing ring, the fixing pins are rotated to the inner walls of the clamping ring and the fixing ring. The fixing pins can limit the position of the limiting ring and the clamping ring.

[0009] Preferably, the side wall of the support frame is fixedly connected with a hook, so that when it is necessary to carry some tools, the tool bag can be hung on the hook, and the hook can be conveniently used to store items.

[0010] Preferably, the upper surface of the support frame is provided with an adjustment device, the adjustment device including a support block, the bottom end of the support block being fixedly connected to the upper surface of the support frame, a threaded rod being rotatably connected to the side wall of the support block, a connecting block being fixedly connected to the upper surface of the movable block, the inner wall of the connecting block being threadedly connected to the surface of the threaded rod, and the rotation of the threaded rod driving the connecting block and the movable block to move. By setting the support block, the threaded rod and the connecting block, the position of the movable block can be easily adjusted, and the position of the movable block can also be restricted.

[0011] Preferably, a fixing block is fixedly connected to the upper surface of the support frame near the threaded rod. The inner wall of the fixing block is rotatably connected to the surface of the threaded rod. When the threaded rod rotates, the threaded rod rotates on the inner wall of the fixing block, and the fixing block can support the threaded rod.

[0012] Preferably, a knob is fixedly connected to the side wall of the threaded rod. When it is necessary to operate the threaded rod, the knob is rotated to make the threaded rod rotate. The knob makes it convenient to operate the threaded rod.

[0013] The advantages of this utility model are:

[0014] 1. When hoisting, the user holds the handle and pushes it, which moves the support frame and base plate. The base plate causes the support wheels to roll on the ground. As the support frame moves, the pulleys on the moving block also move. When the support frame moves, the limiting ring will fit against the column. Then, the clamping ring is pushed to rotate on the surface of the limiting ring. The clamping ring rotates to the surface of the column, and then the fixing pin is rotated to the inner wall of the clamping ring and the limiting ring. When tools need to be carried, the tool bag is hung on the hook surface. After the support frame is fixed in position, the moving block is pushed to slide on the surface of the support frame. The moving block drives the pulleys to move. The pulleys and hoisting ropes are used to hoist the photovoltaic bracket. By setting up the whole device, the photovoltaic bracket can be hoisted conveniently, reducing the inconvenience of using traditional hoisting equipment in the field and affecting the installation efficiency.

[0015] 2. When the pulley position needs to be adjusted, this utility model allows the knob to be turned, causing the threaded rod to rotate. The threaded rod rotates on the side wall of the support block, the inner wall of the connecting block, and the inner wall of the fixed block. The threaded rod drives the connecting block and the moving block to move their positions. The moving block then drives the pulley to move. By using the pulley, the position of the pulley can be easily adjusted to meet installation needs. During hoisting, it can reduce wear between the bracket and the column. After hoisting to a suitable height, it can also be easily adjusted so that the bracket is moved directly above the column, thus facilitating the installation of the bracket and the column.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 As shown, a hoisting device for a photovoltaic support structure in a plain includes a column 1, a pulley 2, and a support device 4. The pulley 2 is located directly above the column 1, and a hoisting rope 3 is inserted into the inner surface of the pulley 2. The support device 4 is located on one side of the column 1 and includes a base plate 41. The base plate 41 is located on one side of the column 1, and two support wheels 42 are rotatably connected to the inner surfaces of both sides of the base plate 41. A support frame 43 is fixedly connected to the upper surface of the base plate 41. The surface of the support frame 43... A sliding block 44 is slidably connected, and the bottom end of the sliding block 44 is fixedly connected to the upper surface of the pulley 2. During operation, the base plate 41 is pushed to drive the support wheel 42 to rotate. The support wheel 42 rolls on the ground. When the base plate 41 moves, it will drive the support frame 43 and the pulley 2 on the sliding block 44 to move. Then, the photovoltaic bracket is hoisted using the hoisting rope 3. By setting the base plate 41, support wheel 42, support frame 43 and sliding block 44, the photovoltaic bracket can be hoisted conveniently, and the entire equipment can also be moved conveniently.

[0025] A handle 45 is fixedly connected to the side wall of the support frame 43. When working, holding the handle 45 and pushing the handle 45 will cause the support frame 43 to move. The handle 45 makes it easy to move the support frame 43.

[0026] Multiple limiting rings 46 are fixedly connected to the side wall of the support frame 43. A clamping ring 47 is rotatably connected to the surface of the limiting ring 46. The limiting ring 46 and the clamping ring 47 are sleeved on the surface of the column 1. During operation, the support frame 43 drives the limiting ring 46 to fit against the column 1, and then pushes the clamping ring 47 to rotate to the surface of the column 1. By setting the limiting ring 46 and the clamping ring 47, the position between the support frame 43 and the column 1 can be restricted.

[0027] The inner walls of the clamping ring 47 and the fixed ring are threadedly connected with a fixing pin 48. During operation, the fixing pin 48 is rotated to the inner walls of the clamping ring 47 and the fixed ring. The fixing pin 48 can limit the position of the limiting ring 46 and the clamping ring 47.

[0028] The side wall of the support frame 43 is fixedly connected with a hook 49; when working, the tool bag is hung on the hook 49, and the hook 49 is designed to facilitate the storage of items.

[0029] The upper surface of the support frame 43 is provided with an adjustment device 5. The adjustment device 5 includes a support block 51. The bottom end of the support block 51 is fixedly connected to the upper surface of the support frame 43. A threaded rod 52 is rotatably connected to the side wall of the support block 51. A connecting block 53 is fixedly connected to the upper surface of the moving block 44. The inner wall of the connecting block 53 is threadedly connected to the surface of the threaded rod 52. During operation, rotating the threaded rod 52 causes it to rotate between the inner wall of the connecting block 53 and the side wall of the support block 51. When the threaded rod 52 rotates, it drives the connecting block 53 and the moving block 44 to move. By setting the support block 51, the threaded rod 52 and the connecting block 53, the position of the moving block 44 can be easily adjusted and the position of the moving block 44 can also be restricted.

[0030] A fixing block 54 is fixedly connected to the upper surface of the support frame 43 near the threaded rod 52. The inner wall of the fixing block 54 is rotatably connected to the surface of the threaded rod 52. During operation, the threaded rod 52 rotates on the inner wall of the fixing block 54, and the fixing block 54 can support the threaded rod 52.

[0031] A knob 55 is fixedly connected to the side wall of the threaded rod 52. During operation, rotating the knob 55 causes the threaded rod 52 to rotate. The knob 55 facilitates the operation of the threaded rod 52.

[0032] Working principle: During hoisting, gripping handle 45 and pushing it moves the support frame 43 and base plate 41. The base plate 41 causes the support wheel 42 to roll on the ground. The movement of the support frame 43 also moves the pulley 2 on the moving block 44. As the support frame 43 moves, the limiting ring 46 will adhere to the column 1. Then, pushing the clamping ring 47 allows it to rotate on the surface of the limiting ring 46. The clamping ring 47 rotates to the surface of the column 1, and then the fixing pin 48 rotates to the inner wall of the clamping ring 47 and the limiting ring 46. When tools are needed, the tool bag is hung on the hook 49. After the support frame 43 is fixed in position, pushing the moving block 44 allows it to slide on the surface of the support frame 43. The moving block 44 moves the pulley 2. The pulley 2 and the hoisting rope 3 are used to hoist the photovoltaic support. The hoisting system facilitates the lifting of photovoltaic brackets, reducing the inconvenience of using traditional hoisting equipment in the field and thus improving installation efficiency. When the position of pulley 2 needs to be adjusted, rotating knob 55 causes threaded rod 52 to rotate. Threaded rod 52 rotates on the side wall of support block 51, the inner wall of connecting block 53, and the inner wall of fixing block 54. Threaded rod 52 drives connecting block 53 and moving block 44 to move. Moving block 44 then moves pulley 2. By using the pulley 2, the position of pulley 2 can be easily adjusted to meet installation needs. This reduces wear between the bracket and column 1 during hoisting. After hoisting to the appropriate height, the bracket can be easily adjusted to move directly above column 1, facilitating the installation of the bracket and column 1.
