Description

Technical Field

[0001] The present application relates to the field of box-type transformer platforms, and particularly to a water lifting device for a photovoltaic box-type transformer platform. Background Art

[0002] Photovoltaic power generation, as a new power generation mode, is generally applied in areas with relatively rich light resources, and usually includes mountain photovoltaic power generation, photovoltaic power generation in coal mining subsidence areas, photovoltaic power generation on ponds (fish-light complementary), floating photovoltaic power generation, photovoltaic power generation on farmland (agriculture-light complementary), and other on-land photovoltaic power generations.

[0003] A floating photovoltaic box-type transformer platform refers to a platform located on the water surface in a floating photovoltaic array for installing a box-type transformer, which is a one-stop solution for the inverter unit from the DC output link of photovoltaic modules to the grid connection link.

[0004] However, due to being in a water environment and with the passage of years, the box-type transformer platform will decline as a whole after several years of operation. If the box-type transformer and the platform are not lifted in time, the box-type transformer platform will face the situation of being flooded by water during the rainy season, resulting in damage to the box-type transformer.

[0005] Currently, in order to prevent the box-type transformer platform from being easily flooded by water during the rainy season, the traditional lifting method generally uses a construction ship to lift the box-type transformer platform. However, the stability of the construction ship itself is poor, and the lifting process cannot control the shaking of the box-type transformer platform, with a large swinging amplitude and poor stability, resulting in low safety. Summary of the Utility Model

[0006] In order to improve the problems existing in the above technology, the present application provides a water lifting device for a photovoltaic box-type transformer platform.

[0007] The present application provides a water lifting device for a photovoltaic box-type transformer platform, adopting the following technical solutions:

[0008] A water lifting device for a photovoltaic box-type transformer platform includes: a box-type transformer platform arranged on a plurality of pipe piles, and a lifting assembly is arranged between the pipe piles and the box-type transformer platform;

[0009] The lifting assembly includes: a hoop, a steel section, a mast, a lifting lug, and a chain block. The hoop is fixed on the pipe pile, the steel section is fixed between adjacent hoops, one end of the mast is connected to the steel section and the other end penetrates through the box-type transformer platform, the lifting lug is fixed on the mast and the box-type transformer platform, and one end of the chain block is connected to the lifting lug on the mast and the other end is connected to the lifting lug on the box-type transformer platform.

[0010] By adopting the above technical solution, during the lifting process, each chain block corresponds to a construction worker, and then the chain blocks are pulled simultaneously to lift the box substation platform; during the lifting process, the mast can limit the box substation platform, so that the box substation platform is not prone to shaking during the lifting process, thereby improving the stability of the lifting of the box substation platform and not easily reducing the safety; finally, pile splicing is carried out between the box substation platform and the pipe pile, thereby completing the lifting of the box substation platform, so that the box substation platform is not easily flooded by water during the rainy season.

[0011] Optionally, a suspension component is arranged between the pipe pile and the hoop. The suspension component includes: a bearing plate, a suspension rope, a suspension hook and a suspension ring. The bearing plate is sleeved on the pipe pile. One end of the suspension rope is connected to the bearing plate and the other end is fixed to the suspension hook. The suspension ring is fixed on the hoop, and the suspension hook is hung on the suspension ring.

[0012] By adopting the above technical solution, after the hoop is installed on the pipe pile, the suspension hook is hung on the suspension ring, so that the suspension rope can suspend the hoop, and thus the hoop is not prone to slipping on the pipe pile.

[0013] Optionally, the suspension component further includes: a spring and a suspension rod. A receiving groove is formed in the bearing plate, and a receiving hole is formed in the inner wall of the receiving groove. The end of the suspension rod is rotatably installed in the receiving hole. One end of the suspension rope away from the suspension hook is fixed to the suspension rod. The spring is sleeved on the suspension rod and one end is fixed to the suspension rod and the other end is fixed to the inner wall of the receiving hole.

[0014] By adopting the above technical solution, after the lifting is completed, the suspension hook is removed from the suspension ring. At this time, the spring resumes deformation to drive the suspension rod to rotate, thereby winding up the suspension rope and storing the suspension rope and the suspension hook in the receiving groove.

[0015] Optionally, a connection component is arranged between the bearing plate and the pipe pile. The connection component includes: a pulling and releasing rope, a connecting rod and a connecting spring. A placement hole is formed in the bearing plate, a connection hole is formed in the pipe pile. One end of the connecting rod is arranged in the placement hole and the other end is arranged in the connection hole. The connecting spring is fixed between the connecting rod and the bottom of the placement hole. One end of the pulling and releasing rope is fixed to the connecting rod and the other end extends outwards through the bearing plate.

[0016] By adopting the above technical solution, if the box substation platform needs to be lifted again later, pull the pulling and releasing rope to pull the connecting rod into the placement hole to release the connection between the bearing plate and the pipe pile; then, move the bearing plate upwards and fix it again, so that the hoop can continue to be suspended.

[0017] Optionally, the connection component further includes: a locking rod and a locking spring. An installation hole is formed in the connecting rod, a locking hole is formed in the inner wall of the connection hole, one end of the locking rod is arranged in the installation hole, and the other end is arranged in the locking hole. The locking spring is fixed between the locking rod and the bottom of the installation hole. The end of the pulling and releasing rope away from the receiving plate is fixed to the locking rod.

[0018] By adopting the above technical solution, the locking rod can limit the connecting rod, thereby further improving the stability of the connection between the receiving plate and the pipe pile.

[0019] Optionally, a fixing component is arranged between the mast and the profiled steel. The fixing component includes: an insertion cylinder, a fixing bolt and a fixing nut. The insertion cylinder is fixed to the profiled steel, the mast is arranged in the insertion cylinder, the fixing bolt penetrates through the insertion cylinder and the mast, and the fixing nut is threadedly sleeved on the fixing bolt and abuts against the insertion cylinder.

[0020] By adopting the above technical solution, after the lifting of the box substation platform is completed, the fixing nut is unscrewed from the fixing bolt, and then the fixing bolt is pulled out, so that the mast can be taken out of the insertion cylinder, thereby improving the disassembly efficiency between the mast and the profiled steel. If welding is used, cutting is required to complete the separation.

[0021] Optionally, the fixing component further includes: a reinforcing rib, and the reinforcing rib is fixed between the insertion cylinder and the profiled steel.

[0022] By adopting the above technical solution, the reinforcing rib can improve the strength of the insertion cylinder, thereby supporting the mast more stably.

[0023] Optionally, the connection component further includes: a hand grip plate, and the hand grip plate is fixedly connected to the end of the pulling and releasing rope away from the connecting rod.

[0024] By adopting the above technical solution, the hand grip plate can more conveniently hold the pulling and releasing rope to pull the pulling and releasing rope.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. The mast can limit the box substation platform, so that the box substation platform is not prone to shaking during the lifting process, thereby improving the stability of the lifting of the box substation platform and not easily reducing the safety.

Detailed implementation manners

[0035] The embodiment of the present application provides a water lifting device for a photovoltaic transformer box platform.

[0036] Referring to Figure 1 , a water lifting device for a photovoltaic transformer box platform includes: a transformer box platform 2 arranged on a plurality of pipe piles 1. In the embodiment of the present application, six pipe piles 1 are provided, three in each group. The two groups of pipe piles 1 are located at both ends of the transformer box platform 2 along the width direction, and each group of pipe piles 1 is arranged along the length direction of the transformer box platform 2.

[0037] Referring to Figure 1, a lifting component 3 is arranged between the pipe pile 1 and the box-type transformer platform 2. The lifting component 3 includes: a hoop 31, a section steel 32, a mast 33, a lifting lug 34 and a chain block 35. The hoop 31 is fixed on the pipe pile 1, and the section steel 32 is welded between the hoops 31 on the adjacent pipe piles 1 in each group and is horizontally arranged. One end of the mast 33 is connected to the top wall of the section steel 32, and the other end penetrates through the box-type transformer platform 2 and extends upward. In the embodiment of the present application, the number of masts 33 is the same as that of the pipe piles 1 and they correspond one by one. The mast 33 can limit the box-type transformer platform 2, so that the box-type transformer platform 2 is not easy to shake during the lifting process, thereby improving the stability of the lifting of the box-type transformer platform 2 and not easily reducing the safety.

[0038] See Figure 1 , the lifting lugs 34 are fixed on the top wall of the mast 33 and the top wall of the box-type transformer platform 2; one end of the chain block 35 is connected to the lifting lug 34 on the mast 33, and the other end is connected to the lifting lug 34 on the box-type transformer platform 2. Before lifting, install the hoop 31 on the pipe pile 1, then weld the section steel 32 between the adjacent hoops 31, then pass the mast 33 through the box-type transformer platform 2 and connect it to the section steel 32; secondly, connect the chain block 35 to the corresponding lifting lug 34; finally, cut the pipe pile 1 and the box-type transformer platform 2;

[0039] During lifting, each chain block 35 corresponds to a construction worker, and then pull the chain block 35 simultaneously to lift the box-type transformer platform 2; then connect the piles between the box-type transformer platform 2 and the pipe pile 1, thereby completing the lifting of the box-type transformer platform 2, so that the box-type transformer platform 2 is not easy to be flooded by water during the rainy season.

[0040] See Figure 1 , further, a fixing component 6 is arranged between the mast 33 and the section steel 32. The fixing component 6 includes: an insertion cylinder 61, a fixing bolt 62 and a fixing nut 63. The insertion cylinder 61 is welded on the top wall of the section steel 32, and one end of the mast 33 away from the lifting lug 34 is arranged in the insertion cylinder 61. The fixing bolt 62 horizontally penetrates through the insertion cylinder 61 and the mast 33, and the fixing nut 63 is threadedly sleeved on the fixing bolt 62 and abuts against the outer side wall of the insertion cylinder 61. After the lifting of the box-type transformer platform 2 is completed, unscrew the fixing nut 63 from the fixing bolt 62, and then pull out the fixing bolt 62, then the mast 33 can be taken out of the insertion cylinder 61, thereby improving the disassembly efficiency between the mast 33 and the section steel 32. If welding is used, cutting is required to complete the separation.

[0041] See Figure 1 , further, the fixing component 6 further includes: a reinforcing rib 64. The reinforcing rib 64 is welded between the outer side wall of the insertion cylinder 61 and the top wall of the section steel 32. The reinforcing rib 64 can improve the strength of the insertion cylinder 61, thereby being able to support the mast 33 more stably.

[0042] SeeFigure 2 , Figure 3 and Figure 4 , further, a suspension assembly 4 is provided between the pipe pile 1 and the hoop 31. The suspension assembly 4 includes: a receiving plate 41, a suspension rope 42, a suspension hook 43 and a suspension ring 44. The receiving plate 41 is sleeved on the pipe pile 1, and one end of the suspension rope 42 is connected to the receiving plate 41 and the other end is fixedly connected to the suspension hook 43. The suspension ring 44 is fixed on the outer side wall of the hoop 31, and the suspension hook 43 is hung on the suspension ring 44. After the hoop 31 is installed on the pipe pile 1, the suspension hook 43 is hung on the suspension ring 44, so that the suspension rope 42 can suspend the hoop 31, and thus the hoop 31 is not likely to slip on the pipe pile 1.

[0043] See Figure 5 , further, the suspension assembly 4 further includes: a spring 45 and a suspension rod 46. A receiving groove 411 is formed in the bottom wall of the receiving plate 41, and a receiving hole 412 is formed in the inner side wall of the receiving groove 411. The suspension rod 46 is located in the receiving groove 411, and the end of the suspension rod 46 is rotatably installed in the receiving hole 412; one end of the suspension rope 42 away from the suspension hook 43 is fixedly connected to the suspension rod 46.

[0044] See Figure 5 , the spring 45 is sleeved on one end of the suspension rod 46 located in the receiving hole 412, and one end of the spring 45 is fixed to the suspension rod 46 and the other end is fixed to the inner wall of the receiving hole 412. After the hoop 31 is installed, the suspension hook 43 is pulled to the suspension ring 44 for hanging. During this process, the spring 45 is deformed; after the lifting is completed, the suspension hook 43 is removed from the suspension ring 44. At this time, the spring 45 restores its deformation to drive the suspension rod 46 to rotate, so as to wind up the suspension rope 42 and store the suspension rope 42 and the suspension hook 43 in the receiving groove 411.

[0045] See Figure 5 , further, a connection assembly 5 is provided between the receiving plate 41 and the pipe pile 1. The connection assembly 5 includes: a pulling and releasing rope 51, a connecting rod 52 and a connection spring 53. An installation hole 413 is formed in the inner side wall of the receiving plate 41, and a connection hole 11 is formed in the outer side wall of the pipe pile 1. One end of the connecting rod 52 is arranged in the installation hole 413 and the other end is arranged in the connection hole 11. One end of the connection spring 53 is fixed to the bottom of the installation hole 413 and the other end is fixed to the connecting rod 52. The connection spring 53 is used to push the connecting rod 52 to insert into the connection hole 11.

[0046] See Figure 5, One end of the pulling and releasing rope 51 is connected to the connecting rod 52, and the other end penetrates through the bearing plate 41 and extends outwards. If the box-type transformer platform 2 needs to be lifted again later, pull the pulling and releasing rope 51 to pull the connecting rod 52 into the placement hole 413 to release the connection between the bearing plate 41 and the pipe pile 1; then, move the bearing plate 41 upwards and fix it again, so that the suspension pulling of the hoop 31 can continue.

[0047] See Figure 5 , Further, the connecting component 5 further includes: a locking rod 54 and a locking spring 55. One end of the connecting rod 52 located in the connection hole 11 is provided with an installation hole 521, and the inner wall of the connection hole 11 is provided with a locking hole 12. One end of the locking rod 54 is arranged in the installation hole 521 and the other end is arranged in the locking hole 12. The locking rod 54 can limit the connecting rod 52, so as to further improve the connection stability between the bearing plate 41 and the pipe pile 1. One end of the locking spring 55 is fixed to the locking rod 54 and the other end is fixed to the bottom of the installation hole 521. The locking spring 55 is used to push the locking rod 54 into the locking hole 12.

[0048] See Figure 5 , One end of the pulling and releasing rope 51 far from the connecting rod 52 penetrates into the installation hole 521 and is fixed to the locking rod 54. If the box-type transformer platform 2 needs to be lifted again later, pull the pulling and releasing rope 51 to first pull the locking rod 54 into the installation hole 521, and then continue to apply a pulling force to pull the connecting rod 52 into the placement hole 413, so as to release the connection between the bearing plate 41 and the pipe pile 1.

[0049] See Figure 5 , Further, the connecting component 5 includes: a hand-gripping disc 56. The hand-gripping disc 56 is fixedly connected to one end of the pulling and releasing rope 51 far from the locking rod 54 and abuts against the top wall of the bearing plate 41. The hand-gripping disc 56 can make it more convenient to pull the pulling and releasing rope 51.
