Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic installation equipment, in particular to a leg-type special construction platform for a photovoltaic panel and a fixing bracket thereof. Background Art

[0002] As a new field of photovoltaic power generation, offshore photovoltaic power generation has broadened the space for photovoltaic power generation and opened up a new path for building a new green and low-carbon energy system and promoting the upgrading of energy supply structure. Offshore photovoltaic projects near the coast widely use fixed pile group foundations as the foundation of offshore photovoltaics. The efficient and safe installation of trusses, photovoltaic fixed brackets and photovoltaic modules between dense pile groups requires a lot of manpower, materials, equipment and funds for construction.

[0003] At present, in offshore photovoltaic projects, photovoltaic fixed brackets and photovoltaic modules are installed between dense pile groups by setting up scaffolding platforms between piles, and personnel perform installation on fixed platforms. The main process is: construction personnel take a boat to install clamps on the piles during high tide, install horizontal I-beams or H-shaped steel on the clamps, set up horizontal and vertical round steel pipes on the steel, connect the steel pipes into a whole by using bayonet joints, lay scaffolding boards on the steel pipe grid, fix the scaffolding boards, and build a fixed platform between the piles.

[0004] For example, the Chinese patent publication number CN118563741A is a work platform for installing offshore photovoltaic racks and its installation method, which belongs to the technical field of offshore photovoltaic rack installation. The work platform includes a supporting mechanism, a positioning mechanism and a guide plate; the supporting mechanism includes a plurality of supporting beams arranged in a circle along the pipe pile, and an operating platform arranged on the supporting beams; the positioning mechanism is fixed to the supporting mechanism, and the positioning mechanism includes an annular fixing member for fixing the supporting mechanism around the pipe pile; the guide plate is fixed to the annular fixing member, and is used to temporarily constrain the photovoltaic rack to the pipe pile. The operating platform is fixed to the annular fixing member, and is arranged around the pipe pile through the annular fixing member, which can provide a stable environment for the installation of the photovoltaic rack and prevent excessive wind and waves from interfering with the installation operation.

[0005] For example, an offshore photovoltaic support integrated installation system with Chinese patent publication number CN220067272U includes: a photovoltaic support module; a transportation module, which is detachably connected to the photovoltaic support module and is configured to transport the photovoltaic support module to the target installation site and complete the installation of the photovoltaic support module and the pile foundation; wherein the photovoltaic support module includes: a tire frame module, which is detachably connected to the transportation module; a truss module, which is detachably connected to the tire frame module; and a photovoltaic module, which is detachably connected to the truss module.

[0006] At present, the photovoltaic construction platforms on the market are not convenient for rapid assembly and construction of photovoltaics because they are installed in a splicing manner. At the same time, the existing photovoltaic construction platforms float on the water, which causes shaking when assembling photovoltaic components, making it impossible for the existing photovoltaic construction platforms to perform guided lifting and stable positioning. Therefore, a device is needed to improve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] The present invention is further described below in conjunction with the accompanying drawings.

[0025] Embodiment 1, as Figure 1 and Figure 2 As shown, a photovoltaic panel of the present invention comprises a pipe pile 9, a truss 10 is installed on the top of the pipe pile 9, and a photovoltaic panel 7 is fixedly installed on the top of the truss 10.

[0026] A special construction platform of the leg type with a fixed support comprises a first construction platform 3, a first leg 1 and a second leg 6 are symmetrically fixedly installed at the front and rear ends of the top of the first construction platform 3, a lifting device 2 is fixedly installed on the top of the first construction platform 3 close to the first leg 1, a crane 11 is symmetrically arranged at the top of the first construction platform 3, a slide rail 4 is symmetrically arranged at the top of the first construction platform 3 away from the first leg 1, a ship changing device 5 is arranged at the top of the slide rail 4, a hydraulic device 8 is installed inside the ship changing device 5, and a winch 12 is arranged at the four corners of the top of the first construction platform 3.

[0027] The working principle of embodiment 1 is as follows: when in use, after the installation of two rows of pipe piles 9 is completed, the spacing between the pipe piles 9 satisfies the horizontal spacing of the piles being less than 8m and the longitudinal spacing being more than 16m. The first construction platform 3 is towed between the two groups of pipe piles 9 by the anchor boat. After the first construction platform 3 is flush with the pipe piles 9, the winch 12 on the first construction platform 3 is turned on, so that the first leg 1 and the second leg 6 are quickly inserted into the mud under the action of gravity to stabilize the hull. The first leg 1 and the second leg 6 are not fixed to the first construction platform 3, and the platform can move up and down with the tide. After the first construction platform 3 is stable, the crane 11 is started at the same time to lift the truss 10 placed on the first construction platform 3 in advance, place the truss 10 on the top of the pipe piles 9, and fix it. After the installation of the truss 10 is completed, the staff can assemble the photovoltaic fixed bracket and the photovoltaic module on the jacking device 2. After all the modules are assembled, the jacking device 2 is started. The jacking device 2 moves to the top of the truss 10, and the staff places the fixed bracket and the photovoltaic panel on the truss 10 and fixes them with bolts to complete the installation of the photovoltaic components of a photovoltaic matrix. After the photovoltaic components in the photovoltaic matrix are installed, the jacking device 2 descends. At this time, the two winches 12 at the front of the first construction platform 3 are started first to lift the first leg 1 to make it separate from the mud surface, and under the push of the hydraulic device 8, the first construction platform 3 moves a pile distance, and the winch 12 at the front end of the first construction platform 3 starts to be lowered, and the first leg 1 is inserted into the mud to stabilize the platform. Subsequently, the winch 12 at the rear end of the top of the first construction platform 3 is started again to separate the second leg 6 from the mud surface. The hydraulic device 8 is started again, and with the first leg 1 as the fulcrum, the entire hull is driven to move a pile distance, and then the second leg 6 is released to stabilize the platform, and the action of the previous unit is executed to complete the installation of the photovoltaic components in the next photovoltaic matrix.

[0028] Embodiment 2, on the basis of embodiment 1, as Figure 3 As shown, the first construction platform 3 further includes a side end device 13 and a supporting component 14 , and the side end device 13 is slidably inserted on both sides of the top of the supporting component 14 .

[0029] like Figure 4 The side end device 13 includes a guide rod 15, a first spring 16, an outer bracket 17, an inner bracket 18 and a transmission rack 19. The transmission rack 19 is symmetrically fixedly installed on the left side of the inner bracket 18. The outer bracket 17 is slidably inserted into the right side of the inner bracket 18. The first spring 16 is symmetrically fixedly installed between the outer bracket 17 and the inner bracket 18. The guide rod 15 slides through the inner bracket 18 and is connected to the left side of the outer bracket 17. The setting of the guide rod 15 can prevent the outer bracket 17 from being skewed when it is displaced.

[0030] like Figure 5The supporting component 14 includes a positioning device 20, a transmission device 21 and a guide device 22. The positioning device 20 is symmetrically fixedly installed at the two ends of the top of the guide device 22, and the transmission device 21 is symmetrically rotationally installed at the centers of the two ends of the guide device 22, which can support the positioning device 20 to perform guiding and positioning work.

[0031] like Figure 6 The alignment device 20 includes an alignment bracket 23, a support vertical plate 24, a second spring 25, a connecting base plate 26, a connecting rope 27, a positioning base plate 28, a first gear 29 and a winding wheel 30. The first gear 29 is rotatably mounted on the positioning base plate 28, the winding wheel 30 is fixedly mounted on the rear end center of the first gear 29, the connecting rope 27 is fixedly mounted on the outer ring of the winding wheel 30, the connecting base plate 26 is fixedly mounted on the end of the connecting rope 27 away from the winding wheel 30, the alignment bracket 23 and the second spring 25 are fixedly mounted on the top and bottom of the side end of the connecting base plate 26 away from the connecting rope 27, and the supporting vertical plate 24 is fixedly mounted on the end of the second spring 25 away from the connecting base plate 26, and can be buckled on the outer ring of the pipe pile 9 through the alignment bracket 23, so that the first construction platform 3 can be stably restricted.

[0032] like Figure 7 The transmission device 21 includes a second gear 31 and a transmission worm wheel 32. The second gear 31 is fixedly mounted at the side end center of the transmission worm wheel 32. When the transmission worm 37 drives the transmission worm wheel 32 to rotate, the second gear 31 can be driven to rotate at the same time.

[0033] like Figure 8 The guide device 22 includes a second construction platform 33, a guide sleeve 34, a dual-axis motor 35, a propeller drive system 36 and a transmission worm 37. The guide sleeve 34 is fixedly installed at the four corners of the top of the second construction platform 33, the dual-axis motor 35 is fixedly installed at the centers of both ends of the second construction platform 33, the transmission worm 37 is fixedly installed at the centers of both ends of the dual-axis motor 35 close to the guide sleeve 34, and the propeller drive system 36 is symmetrically arranged at the rear end bottom of the second construction platform 33. Through the setting of the propeller drive system 36, the second construction platform 33 can be driven to move as a whole.

[0034] The inner bracket 18 is slidably inserted into the inside of the guide sleeve 34, the transmission worm gear 32 is symmetrically rotatably installed at both ends of the second construction platform 33, and the transmission worm gear 32 is meshed with the transmission worm 37, the bottom end of the support vertical plate 24 is connected to the top of the second construction platform 33 close to the guide sleeve 34, the positioning base plate 28 is fixedly installed on the top of the second construction platform 33 close to the dual-axis motor 35, the transmission rack 19 is meshed with the top of the second gear 31, the first gear 29 is meshed with the side end of the second gear 31, and the first gear 29 is located below the transmission rack 19, the bottom end of the connecting base plate 26 is symmetrically fixed with a card key, and the second construction platform 33 is symmetrically provided with a card slot near the top of the guide sleeve 34, a circular groove is provided at the center of the side end of the positioning card frame 23 away from the connecting rope 27, and a square hole is provided inside the guide sleeve 34.

[0035] When implementing this embodiment, the propeller drive system 36 is started so that the second construction platform 33 can move between the two groups of pipe piles 9. At the same time, the dual-axis motor 35 is turned on to drive the clockwise transmission worm 37 to rotate, and the transmission worm wheel 32 is meshed with the transmission worm 37, so that when the transmission worm 37 rotates, it can drive the transmission worm wheel 32 and the second gear 31 to rotate at the same time, and through the transmission rack 19 meshing with the top of the second gear 31, when the second gear 31 rotates, it can drive the inner peripheral bracket 18 to an end position away from the second construction platform 33 until the outer peripheral bracket 17 moves to contact the surface of the pipe pile 9 close to the second construction platform 33, thereby preventing the second construction platform 33 from tilting during driving. Through the setting of the first spring 16, the outer bracket 17 can be allowed to move inwardly of the inner bracket 18. A plastic gasket is fixedly installed on the surface of one end of the outer bracket 17 away from the inner bracket 18, so that the outer bracket 17 and the pipe pile 9 can be prevented from having a rigid collision. In addition, when the second construction platform 33 shakes left and right, the outer bracket 17 can be displaced toward the end close to the inner bracket 18. When the outer bracket 17 is completely in contact with the inner bracket 18, the maximum formation can be achieved to avoid continuous deviation of the second construction platform 33. Subsequently, when the second construction platform 33 travels to the designated working area, the propeller drive system 36 can be turned off, and then the dual-axis motor 35 can be started to drive the transmission worm 37 to rotate counterclockwise, so that the second gear 31 can drive the transmission gear The strip 19 is displaced toward one end close to the second construction platform 33, causing the peripheral bracket 17 to be out of contact with the pipe pile 9. At the same time, when the second gear 31 is rotating, it can drive the first gear 29 to rotate, and the first gear 29 can drive the winding wheel 30 to rotate, thereby releasing the connecting rope 27. The elasticity of the second spring 25 will pull the alignment bracket 23 to one end away from the winding wheel 30 until the winding wheel 30 completely releases the connecting rope 27. The alignment bracket 23 is buckled on the outer ring surface of the pipe pile 9, thereby restricting the second construction platform 33 between the pipe piles 9. When the connecting base plate 26 is displaced, the key at the bottom end of the connecting base plate 26 slides in the card groove inside the top end of the second construction platform 33, so that it can be ensured that the alignment bracket 23 moves along a straight line. The alignment bracket 23 is buckled on the pipe pile 9 to ensure the stable support of the second construction platform 33. After that, after the photovoltaic panel 7 is installed, the dual-axis motor 35 can be started again to drive the transmission worm 37 to rotate clockwise, so that the second gear 31 can drive the transmission rack 19 to move to the end away from the second construction platform 33 again, until the outer bracket 17 contacts with the pipe pile 9 again, ensuring that the second construction platform 33 moves in a straight line. At the same time, the second gear 31 will also drive the first gear 29 to rotate again, so that the winding wheel 30 can pull the connecting rope 27 to drive the alignment bracket 23 to disengage from the pipe pile 9, so that the second construction platform 33 can continue to move to the front end.The propeller drive system 36 is located below the second construction platform 33, so that the propeller drive system 36 can always be located below the water surface, so that when the propeller drive system 36 is started, it can provide power for the second construction platform 33 to complete the work.
