Description

TECHNICAL FIELD

[0001] The application relates to a fishing-light complementary photovoltaic panel triangular support water hoisting device, and belongs to the technical field of photovoltaic panel triangular support water construction. BACKGROUND

[0002] With the vigorous development of new energy technology, wind power and photovoltaic power have become the mainstream of new energy development, especially the construction of fishing-light complementary photovoltaic power generation bases in coastal areas has developed rapidly. In the process of water photovoltaic power station construction, the installation quality of photovoltaic panels is an important link. During the installation and construction of water photovoltaic panels, the installation quality and efficiency of photovoltaic triangular supports are the most important link. At present, photovoltaic support installation mostly relies on material transportation by transport ships, and the hoisting of photovoltaic supports depends on ship cranes or the erection of scaffolds on the upper part of the transport ships for photovoltaic panel support installation. All hoisting operations are based on a dynamic water construction platform (such as a ship) as the only operation reference. The water platform is easily shaken and displaced by wind and waves, and is difficult to operate and has many safety hazards due to the influence of wind and waves. Moreover, large hoisting equipment cannot be used on non-powered or small ships, and manual transportation is inefficient and risky. SUMMARY

[0003] The application provides a fishing-light complementary photovoltaic panel triangular support water hoisting device without power supply or suitable for small ships. The entire hoisting device is detachably rigidly connected to a static precast pile body through an adapter mechanism, so that the operation reference originally relying on a dynamic water platform is quickly switched to a fixed precast pile body, thereby fundamentally overcoming the influence of ship shaking on hoisting operations to improve installation positioning accuracy. Through the cooperation of the support structure and the lifting mechanism, the lifting mechanism provides a pre-set trajectory and attitude constraint for the photovoltaic support, so that the photovoltaic support takes the precast pile body as a stable reference to guide and constrain the motion trajectory and attitude of the hoisted support, enabling the support to perform controllable spatial displacement along the pre-set path and avoiding attitude loss of control or swinging to reduce the risk of collision and misalignment of the support and the precast pile during installation docking. The device can realize support hoisting through the principle of pulley set, is suitable for non-powered and small ship scenes, and does not need to rely on external power supply or large power equipment, thereby solving the above-mentioned problems of the prior art, i.e., the water hoisting operation is easily influenced by wind and waves and is easily shaken and displaced, resulting in high difficulty in operation; and large hoisting equipment cannot be used on non-powered or small ships, and manual transportation is inefficient and risky.

The switching mechanism is connected with the support structure at one end, and is detachably connected with the prefabricated pile body at the other end, so that the whole device is rigidly connected to the prefabricated pile body, thereby enabling the unstable water construction platform to be kept relatively stable based on the prefabricated pile body, and realizing quick switching and cyclic anchoring of the working reference of the whole device between the dynamic water construction platform and the static prefabricated pile.

[0004] Preferably, the lifting mechanism comprises a lifting tool, a fixed support frame and a pulley assembly. The fixed support frame is respectively installed on the top of the support structure and faces and faces away from the prefabricated pile body. The fixed support frame provides two mounting points for the pulley assembly to constrain the posture of the hoisted support and provide a preset trajectory. The mounting point on the side facing the prefabricated pile body is higher than the mounting point on the side facing away from the prefabricated pile body. The pulley assembly comprises a first fixed pulley, a second fixed pulley, a third fixed pulley and a rope. The first fixed pulley and the second fixed pulley are respectively installed on the mounting point on the side facing the prefabricated pile body and the mounting point on the side facing away from the prefabricated pile body. The third fixed pulley is located below the second fixed pulley, and the third fixed pulley is installed on the side of the support structure facing away from the prefabricated pile body. One end of the rope is connected to the third fixed pulley, and the other end of the rope is sequentially wound through the second fixed pulley and the first fixed pulley and connected with the lifting tool.

[0005] Preferably, the diameter of the third fixed pulley is 5 times the diameter of the first fixed pulley and the second fixed pulley, and the height of the third fixed pulley from the bearing base body is adapted to the height of the human body operation.

[0006] Preferably, the fixed support frame is a triangular truss structure. The top corners of the fixed support frame are higher than the top of the support structure. The top corner of the fixed support frame on the side facing the prefabricated pile body provides a mounting point for the first fixed pulley, and the top corner of the fixed support frame on the side facing away from the prefabricated pile body provides a mounting point for the second fixed pulley.

[0007] Preferably, one side of the fixed support frame is formed by the pile body on the side of the support structure facing and facing away from the prefabricated pile body, and the other two sides of the fixed support frame are respectively two inclined struts inclined upward away from the support structure. Two ends of the two diagonal struts are respectively connected to the front and rear sides of the support structure, and the other ends of the two diagonal struts are connected to form a top corner.

[0008] Preferably, the diameter of the first fixed pulley is 1.5 to 2 times the diameter of the second fixed pulley. The height difference between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 50 to 100 mm, the horizontal distance between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 400 to 600 mm, and the longitudinal distance between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 0.

[0009] Preferably, the support structure is higher than the precast pile, and the height difference between the two is greater than the maximum height of the hoisted object.

[0010] Preferably, the adapter mechanism includes a clasp that can be opened and closed and a rotating connecting piece. The clasp can be opened and closed around the precast pile. The rotating connecting piece is located between the clasp and the support structure, one end of the rotating connecting piece is connected to one side of the support structure facing the precast pile, and the other end of the rotating connecting piece is movably connected to the clasp, so that the hoisting device can rotate around the precast pile.

[0011] The beneficial effects that can be produced by the present application include: In the present application, by setting the adapter mechanism, one end of the adapter mechanism is connected to the support structure, and the other end is connected to the precast pile, the support structure and the lifting mechanism located on the support structure can be connected to the fixed precast pile during operation, thereby transferring the unstable transport ship platform relied on by the water installation operation to the stable precast pile. Not only does it overcome the influence of ship sway on installation safety. At the same time, its quick assembly provides protection for the device to realize construction by fixing a point; and the device adjusts the angle around the pile body to adapt to the hoisting needs in different directions, improving the operation flexibility.

[0012] The lifting mechanism is based on the force-saving and guiding principle of the pulley block, uses the precast pile body as a stable reference, can guide and constrain the movement trajectory and attitude of the hoisted support, make the support perform controllable spatial displacement according to the preset path, avoid attitude out of control or swinging, reduce the collision and misplacement risk when the support and the precast pile are installed and connected, and simplify the installation operation process.

[0013] By setting the fixed support structure as a triangular truss structure, the complex diagonal load borne by the pulley is decomposed and transmitted to the support structure, ensuring high rigidity, high strength and fatigue resistance of the local support point under the conditions of simple materials and on-site welding. ​

[0014] The present application can realize the hoisting of the hoisted piece by the pulley block without power or power equipment; in the pulley block, the first fixed pulley and the second fixed pulley are arranged high and low, which naturally forms the guide for the hoisting rope wound thereon, so that the hoisted piece (i.e. the photovoltaic support) assumes an inclined posture, which conforms to the motion trajectory of installation in place, and effectively restricts the swing of the hoisted piece.

DETAILED DESCRIPTION

[0016] A fishing-light complementary photovoltaic panel triangular support water hoisting device, the device comprising: a bearing base installed on a water construction platform; a support structure installed on one side of the bearing base facing the prefabricated pile; a lifting mechanism installed on the support structure, the lifting mechanism based on the force-saving and guiding principle of the pulley block, taking the prefabricated pile as a stable hoisting reference, guiding and restricting the hoisted support, providing a preset trajectory and posture for the hoisted support, and enabling the hoisted support to perform controllable spatial displacement according to the preset trajectory and posture; a transfer mechanism connected to the support structure at one end, the other end of the transfer mechanism being detachably connected to the prefabricated pile, and the entire device being rotated along the prefabricated pile, so that the unstable water construction platform is kept relatively stable with the prefabricated pile as a reference, realizing the quick switching and cyclic anchoring of the working reference of the entire device between the dynamic water construction platform and the static prefabricated pile.

[0017] It should be noted that: In one embodiment of this application, the precast pile is a PHC pipe pile fixed in the water. In this application, the precast pile is used as the working reference, and the support structure with the lifting mechanism is connected to the precast pile through the transfer mechanism. This realizes the transformation of the dynamic and unstable ship operation environment into a stable and controllable operation environment with the static precast pile as the reference, which fundamentally improves the safety and accuracy of the installation operation on water.

[0018] In one embodiment of this application, the supporting base is a steel plate, which is fixed to the transport ship platform to fix the support structure on the supporting base and prevent the support structure from sliding or tilting on the transport ship.

[0019] Furthermore, the lifting mechanism includes a lifting device, a fixed support frame, and a pulley assembly; The fixed support frame is installed on the top of the support structure on the side facing the precast pile and the side away from the precast pile, respectively. The fixed support frame provides two mounting points for the pulley assembly to constrain the posture of the suspended support and provide a preset trajectory; and the mounting point on the side facing the precast pile is higher than the mounting point on the side away from the precast pile. The pulley assembly includes a first fixed pulley, a second fixed pulley, a third fixed pulley, and a rope; The first fixed pulley and the second fixed pulley are respectively installed on the side facing the precast pile. The third fixed pulley is located below the second fixed pulley and is installed on the side of the support structure opposite to the precast pile. One end of the rope is connected to the third fixed pulley, and the other end of the rope is wound around the second fixed pulley and the first fixed pulley in sequence, and is connected to the lifting device.

[0020] It should be noted that: In this application, the first fixed pulley and the second pulley are installed at different heights on the side of the support structure facing and away from the precast pile, forming the inclined lifting trajectory required by the hoisting rope; this prevents the hoisted part from swinging along the line connecting the first fixed pulley and the second pulley, and is limited by the gap between the precast pile and the support structure, so that the posture of the hoisted part remains unchanged during the hoisting operation.

[0021] The spatial connection between the third fixed pulley and the first and second fixed pulleys forms an optimized path for labor-saving transmission and direction conversion. This enables the precise lifting and installation of large, irregular components onto fixed precast piles along a predetermined inclined path on a floating platform (i.e., a transport ship) with minimal manpower, ensuring safety and stability.

[0022] Further, the third fixed pulley has a diameter of 5 times that of the first fixed pulley and the second fixed pulley, and the height of the third fixed pulley from the bearing base is adapted to the height of the human operator.

[0023] It should be noted that: In an embodiment of the present application, the third fixed pulley on the side away from the support structure is also provided with a rocker.

[0024] In the present application, the third fixed pulley with a large diameter is arranged below the support structure at a height of 1.2-1.5 meters from the bearing base and faces the operator. This realizes the arrangement of the main force point, the third fixed pulley, at a low position and facing the operator, so that the operator can stand stably and exert force, rather than operating at a high position or an awkward angle. The large-diameter pulley serves as a force-saving lever, significantly reducing the manual force required for lifting. Moreover, the position of the third fixed pulley cooperates with the first fixed pulley and the pulley I on the different side above and the second fixed pulley on the same side to complete the force direction conversion: the horizontal and circular rocking force of the operator is converted into an upward lifting force on the fixed support through the lifting rope path. This layout integrates the force-saving mechanism and the motion guide mechanism.

[0025] Further, the fixed support frame is a triangular truss structure. The top corners of the fixed support frame are higher than the top of the support structure. The top corner of the fixed support frame on the side facing the precast pile provides a mounting point for the first fixed pulley, and the top corner of the fixed support frame on the side away from the precast pile provides a mounting point for the second fixed pulley.

[0026] Further, one side of the fixed support frame is composed of the pile body on the side of the support structure facing and away from the precast pile, and the other two sides of the fixed support frame are two inclined struts inclined upward away from the support structure. One end of each of the two inclined struts is connected to the front and rear sides of the support structure, and the other end of each of the two inclined struts forms a top corner.

[0027] It should be noted that: In the present application, the two inclined struts 31 and the part of the support structure as the horizontal side together form a stable triangular force frame; this structure can effectively decompose and convert the oblique tension force borne by the first fixed pulley 2 during lifting into axial force of the inclined struts 31 and transmit it to the support structure 1, ensuring that the mounting points of the first fixed pulley and the second fixed pulley connected by the two inclined struts 31 do not relatively displace under stress. This ensures that the pre-set lifting path remains unchanged under repeated loading, ensuring the repeatability and accuracy of the lifting process. The bending and torsional stiffness and overall stability of the cantilever support point are greatly enhanced.

[0028] Further, the diameter of the first fixed pulley is 1.5 times to 2 times of the diameter of the second fixed pulley, and in an embodiment of the present application, the diameter of the first fixed pulley is preferably 1.5 times of the diameter of the second fixed pulley. The height difference between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 50mm to 100mm, and in an embodiment of the present application, the height difference is preferably 50mm. The horizontal distance between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 400mm to 600mm, and in an embodiment of the present application, the horizontal distance is preferably 450mm. The longitudinal distance between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is 0 (i.e. the longitudinal distance between the mounting point of the first fixed pulley and the mounting point of the second fixed pulley is the same as the distance from the center of the support structure).

[0029] It should be noted that: In the present application, the second pulley is provided to have a larger diameter than the first pulley, so as to further increase the force saving ratio by using the wheel axle principle, and make the operator more labor-saving when shaking.

[0030] The height difference and horizontal distance of the first fixed pulley and the second fixed pulley define the inclination angle and stability of the lifting track.

[0031] Further, the support structure is higher than the prefabricated pile, and the height difference between the two is greater than the maximum height of the hoisted object (i.e. the maximum height of the hoisted photovoltaic triangular support), and generally the height difference between the two is 2500mm.

[0032] The height is set to ensure sufficient installation space after the photovoltaic triangular support is lifted.

[0033] Further, the adapter mechanism comprises an openable and closable hoop and a rotating connecting piece. The hoop is openable and closable around the prefabricated pile. The rotating connecting piece is located between the hoop and the support structure, one end of the rotating connecting piece is connected to the side of the support structure facing the prefabricated pile, and the other end of the rotating connecting piece is movably connected with the hoop, so that the hoisting device can rotate around the prefabricated pile.

[0034] It should be noted that: In one embodiment of this application, the clamp is installed on the precast pile, specifically in the lower region of the precast pile, i.e., within a height range of 0.5 meters to 0.8 meters above the bearing base fixed to the transport ship platform. This height range is the optimal operating height determined through practice, allowing construction personnel standing on the ship deck to easily tighten, loosen, and rotate the clamp without excessive bending or tiptoeing. In one embodiment of this application, the rotating connector is a horizontally positioned rotating rod, one end of which is fixed to the side of the support structure (i.e., the vertical support column) facing the precast pile body by welding or other means; the clamp includes a C-shaped or split-type annular locking part, and on the inner side of the locking part (i.e., the side closer to the support structure), there is an integrally formed connecting ear plate; the connecting ear plate has a through hole adapted to the diameter of the rotating rod. During installation, the through hole of the connecting lug is fitted onto the other end of the rotating rod. That is, the clamp assembly is suspended or fitted onto the other end of the rotating rod via the connecting lug. The connecting lug rotates around the axis of the fixed rotating rod, achieving a hinged connection between the clamp and the supporting structure. This hinged connection allows workers to rotate the working plane of the entire device described in this application to the optimal angle based on the ship's berthing position, the material direction of the lifting frame, or the presence of surrounding obstacles.

[0035] To allow for flexible angle adjustment during operation, this application specifies a rotation range of no less than 180 degrees. This enables construction personnel to rotate the entire device to the most suitable operating direction based on the relative position of the vessel and the precast pile.

[0036] The annular locking part of the clamp assembly has a convenient buckle (e.g., a pin-type, bolt-type, or lever-cam type quick-release buckle) on the side facing away from the support structure (i.e., the open side). When the clamp surrounds the precast pile, by fastening the buckle, the annular locking part forms a closed force ring, tightly clamping the pipe pile. Releasing the buckle allows for quick opening of the clamp, achieving separation from the precast pile. This buckle enables rapid assembly and disassembly between the device described in this application and the precast pile, thereby realizing rapid switching of the operating reference between the dynamic water construction platform and the static precast pile.

[0037] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments. Example 1 like Figures 1-3The image shows a waterborne hoisting and lifting installation device for a photovoltaic triangular support frame for a solar-fishery complementary system, provided in this embodiment. It is suitable for installing photovoltaic triangular support frames on water. In this embodiment, the precast pile is a PHC pipe pile fixed in the water; the bearing base is a steel plate 9; the construction platform is a transport vessel; the pulley assembly includes a first fixed pulley 2, a second fixed pulley 5, a third fixed pulley 8, and a lifting rope 4, wherein the lifting rope is a steel wire rope, and the rotating connector is a rotating rod 13. This embodiment is based on the pulley lifting principle and uses common and simple materials. First, 40*80 square steel is used as a vertical support frame to obtain the support structure. Then, the vertical support frame 16 is installed on the side of the steel plate 9 facing the PHC pipe pile 10. The top height of the vertical support frame 16 is 2500mm higher than the top height of the PHC pipe pile 10. The purpose of this is to ensure that there is sufficient installation space after the support is lifted. The vertical support frame 16 provides force support during the lifting process. The steel plate 9 is fixed to the operating platform of the transport ship. In this embodiment, the bearing base (steel plate 9) is fixed to the middle position of the deck of the transport ship by welding or bolting, and its installation position covers the entire deck of the transport ship. On the other end of the steel plate, which is symmetrical with the vertical support frame, a counterweight of corresponding weight will be placed to counterweight the hull, forming a temporary stabilizing system during the lifting construction to reduce the impact of ship rolling on the operation.

[0038] Next, fixed support frames (including a first fixed bracket 3 on the side facing the PHC precast pipe pile 10 and a second fixed bracket 6 on the side away from the PHC precast pipe pile 10) are welded to the top of the vertical support frame 16. The apex of the first fixed bracket 3 and the apex of the second fixed bracket 6 are both higher than the top of the vertical support frame 16. The vertex of the first fixed bracket 3 serves as the mounting point for the first fixed pulley 2, and the vertex of the second fixed bracket 6 serves as the mounting point for the second fixed pulley 5. The vertex of the first fixed bracket 3 is 50mm higher than the vertex of the second fixed bracket 6. The horizontal distance between the vertex of the first fixed bracket 3 and the vertex of the second fixed bracket 6 is (e.g., ...). Figure 1 The horizontal distance in the left and right directions is 450mm, and the longitudinal horizontal distance between the vertex of the first fixed bracket 3 and the vertex of the second fixed bracket 6 is (e.g., the horizontal distance in the left and right directions is 450mm). Figure 1 The horizontal distance in the front and rear directions is 0. The purpose of this setting is to ensure sufficient installation space when the support is hoisted while minimizing the overall weight of the hoisting support.

[0039] A third fixed pulley 8 is installed at a height of 1.2 to 1.5 meters from the steel plate 9 on the side of the vertical support frame 16 facing the steel plate 9. This height facilitates operation by construction personnel. The diameter of the third fixed pulley 8 is five times that of the first fixed pulley 2 and the second pulley 5. This design utilizes a large-diameter pulley as a lever to significantly reduce the manual force required for lifting. In this embodiment, a manual crank 7 is installed on the side of the third fixed pulley 8 facing the construction personnel for cranking and lifting.

[0040] One end of the suspension rope 4 is fixed to the third fixed pulley 8, and the other end of the suspension rope 4 is passed through the second fixed pulley 5 and the first fixed pulley 2 respectively. The lifting device (i.e. the hook 1) is installed on the other end of the suspension rope 4 to realize the hoisting or lifting of the photovoltaic triangular bracket.

[0041] In this embodiment, a vertical rotating rod 13 is installed on the side of the vertical support frame 16 facing the PHC pipe pile 10 near the bottom (within 0.5 to 0.8 meters of the lower support steel plate). The rotating rod 13 is vertically fixed to the side wall of the vertical support frame 16. A temporary detachable stainless steel clamp 12 with an inner diameter 1 cm larger than the PHC pipe pile is installed on the vertical support frame 16 within 0.5 to 0.8 meters of the lower support steel plate. The clamp 12 is fitted over the corresponding PHC pipe pile 10 and is rotatably connected to the vertical rotating rod 13. The clamp 12 can rotate 180° around the axis of the rotating rod 13. In this embodiment, as shown... Figure 2 and Figure 3 As shown, the clamp 12 has an opening 15 on the side away from the vertical support frame 16. A buckle 11 is provided at the opening 15. The buckle 11 is located on the outside of the clamp 12. One end of the buckle 11 is rotatably connected to the clamp 12 on the side of the opening 15 via a rotating shaft. The other end of the buckle 11 faces the other side of the opening 15. The end of the buckle 11 on the other side of the opening 15 has a U-shaped structure with the opening facing the rotatably connected end of the buckle 11. The clamp 12 has a groove 14 at one end of the U-shaped structure of the buckle 11. The side wall of the slot 14 near the buckle 11 is provided with a connection port that matches the end of the U-shaped structure. One end of the buckle 11 rotates around the connection point with the clamp 12, so that the other end of the buckle 11 (i.e., the U-shaped structure) can be screwed into or out of the slot 14, so that one end of the U-shaped structure can be inserted into the connection slot, thereby opening or closing the clamp 12. It can be locked in when hoisting the triangular support of the photovoltaic panel and opened when the hoisting is completed and transferred, so that it can be reused when transferred to another PHC pipe pile 10.

[0042] The hoisting device described in this embodiment enables a single person to perform the entire hoisting operation of the photovoltaic panel triangular bracket, which originally required three workers to install. This significantly improves construction efficiency. Furthermore, it eliminates the need for workers to operate at heights by erecting scaffolding on the transport ship, enhancing safety. During construction, the clamp 12 is first installed on the rotating rod 13. Then, one open end of the clamp 12 is opened, and the clamp 12 is wrapped around the PHC pipe pile 10 from both sides. The clamp 12 is then fixed at its opening by rotating the buckle 11, connecting the hoisting device to the PHC pipe pile 10. Next, the operator first fixes the hook 1 to the photovoltaic panel triangular bracket to be hoisted. Then, the operator cranks the handle 7, using wire ropes and pulleys to lift the photovoltaic panel triangular bracket from the transport ship to the installation position at the top of the PHC pipe pile 10. After positioning and installation, the clamp is released, and the bracket is moved to the next PHC pipe pile 10 for reuse.

[0043] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
