Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic installation technology, specifically a solar photovoltaic installation lifting structure. Background Technology

[0002] The solar photovoltaic installation lifting structure disclosed in authorization announcement number CN210927523U includes a housing, a motor, a first sliding rod, and a support plate. The right side of the housing is fixedly connected to the left end of the motor, and a transmission gear is fixedly connected to the output end of the motor. A fixing block is fixedly connected to the bottom end of the housing. In use, the motor drives the transmission gear, which in turn drives the driven gear to rotate, which in turn rotates the threaded rod. The first and second rod sleeves on the threaded rod drive the first and second linkage rods to move in opposite directions. This causes the first linkage rod to move, and the second linkage rod to push the first and second push blocks to move. Finally, with the rotation of the first upper guide rod, the second upper guide rod, the first lower guide rod, and the second lower guide rod, the support plate completes the raising and lowering.

[0003] This avoids the problems of relying solely on manual transport of solar photovoltaic panels to high places, which is both unsafe and inconvenient for installation.

[0004] However, during the raising and lowering of the photovoltaic panel, the bottom sides lack support and cannot be raised and lowered synchronously, resulting in uneven force during the raising and lowering process and causing jamming. This solution is not very efficient for raising and lowering. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a solar photovoltaic installation lifting structure that solves the problem of uneven force distribution and lifting jamming caused by the lack of support on both sides of the bottom during the lifting of photovoltaic panels, and the inability of the two sides to lift synchronously.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solar photovoltaic installation lifting structure, including a base plate, a box body fixedly connected to one side of the top of the base plate and a fixing block fixedly connected to the other side of its top, a drive motor being installed inside the box body, the output end of the drive motor being fixedly connected to a threaded cylinder A through the top of the box body, and a threaded cylinder B being rotatably connected to the middle of the surface of the fixing block.

[0007] The A threaded cylinder is internally threaded to the A threaded screw, and the B threaded cylinder is internally threaded to the B threaded screw. The bottom surfaces of both the A and B threaded cylinders are provided with toothed patterns, and a toothed belt is sleeved on the toothed pattern surface to achieve synchronous rotation of the two cylinders. The top ends of the A and B threaded screws are fixedly connected to a platform.

[0008] In one specific embodiment, the output end of the drive motor is rigidly connected to the A threaded cylinder via a coupling, and the B threaded cylinder is rotatably engaged with the fixed block via a ball bearing.

[0009] In a specific embodiment, the toothed pattern is a straight tooth structure distributed along the circumference of the cylinder; the inner surface of the toothed belt is provided with tooth grooves that mesh with the straight tooth structure.

[0010] In one specific embodiment, the bottom surface of the platform is welded and fixed to the top end of threaded screw A, and the bottom surface of the platform is welded and fixed to the top end of threaded screw B.

[0011] In one specific embodiment, a first telescopic rod is vertically arranged on both sides of the top of the fixed block, and a second telescopic rod is vertically arranged on both sides of the top of the box body. The top ends of the first and second telescopic rods are fixedly connected to the bottom surface of the platform.

[0012] In a specific embodiment, the A threaded screw and the B threaded screw have the same thread direction, and the A threaded cylinder and the B threaded cylinder have the same internal thread direction.

[0013] Compared with the prior art, this utility model provides a solar photovoltaic installation lifting structure, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, the meshing synchronous structure design of toothed grooves and toothed belts achieves the absolute synchronous movement of a single motor driving a dual lifting mechanism. The drive motor rigidly drives the A threaded cylinder to rotate through a coupling, and the toothed grooves at its bottom mesh with the toothed belt to link the B threaded cylinder. This completely solves the core problem of jamming caused by the inability of the two sides to lift synchronously in the background technology, ensuring that the platform lifts without tilting and improving the stability of lifting. Through the symmetrical frame design of the double-sided telescopic rods, the lifting platform achieves anti-tilting rigid support. The first telescopic rod at the top of the fixed block and the second telescopic rod at the top of the box form a four-corner support structure, providing vertical guidance and resisting lateral forces throughout the lifting process of the platform, solving the swaying problem caused by the lack of support at the bottom.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 As an embodiment of this utility model, a solar photovoltaic installation lifting structure includes a base plate 1, a box body 2 is fixedly connected to one side of the top of the base plate 1 and a fixing block 3 is fixedly connected to the other side of its top, a drive motor 4 is provided inside the box body 2, the output end of the drive motor 4 passes through the top of the box body 2 and is fixedly connected to a threaded cylinder A 5, and a threaded cylinder B 7 is rotatably connected to the middle of the surface of the fixing block 3.

[0023] The specific problem addressed in this embodiment is the lack of support on both sides of the bottom during the lifting and lowering of the photovoltaic panel, resulting in uneven force distribution and jamming. This invention achieves absolute synchronous movement of a single motor driving a dual lifting mechanism through a meshing synchronous structure design of the toothed groove 9 and the toothed belt 10. The drive motor 4 rigidly drives the A threaded cylinder 5 to rotate via a coupling, and its bottom toothed groove 9 meshes with the toothed belt 10 to link with the B threaded cylinder 7. This completely solves the core problem of jamming caused by the inability to lift and lower synchronously on both sides in the prior art, ensuring no tilting during the lifting and lowering process of the platform 11 and improving lifting stability. The symmetrical frame design of the double-sided telescopic rods provides rigid anti-tilting support for the lifting platform 11. The first telescopic rod 12 at the top of the fixed block 3 and the second telescopic rod 13 at the top of the housing 2 form a four-corner support structure, providing vertical guidance and resisting lateral forces throughout the lifting and lowering process of the platform 11, thus solving the swaying problem caused by the lack of bottom support.

[0024] A threaded cylinder 5 is internally threaded to A threaded screw 6, and B threaded cylinder 7 is internally threaded to B threaded screw 8. Both A threaded cylinder 5 and B threaded cylinder 7 have toothed grooves 9 on their bottom surfaces, and a toothed belt 10 is fitted onto these grooves to achieve synchronous rotation of the two cylinders. The tops of A threaded screw 6 and B threaded screw 8 are fixedly connected to platform 11. In this specific embodiment, the drive motor 4 is started to drive A threaded cylinder 5 to rotate. The toothed grooves 9 at the bottom of the cylinder synchronously drive B threaded cylinder 7 via the toothed belt 10, causing A threaded screw 6 and B threaded screw 8, which rotate in the same direction, to rise and fall synchronously within the threaded cylinders. The drive platform 11 rises or falls smoothly. The toothed belt 10, in conjunction with the toothed grooves 9, ensures strictly synchronous rotation of the two threaded cylinders, eliminating lifting and lowering jams.

[0025] In this specific embodiment, the output end of the drive motor 4 is rigidly connected to the A threaded cylinder 5 via a coupling, and the B threaded cylinder 7 is rotatably engaged with the fixed block 3 via a ball bearing;

[0026] The output shaft of the drive motor 4 is rigidly connected to threaded cylinder A 5 via a coupling. Threaded cylinder B 7 is horizontally positioned on fixed block 3 via ball bearings to reduce frictional resistance. The rigid transmission of the coupling and the support of threaded cylinder B 7 by the ball bearings ensure the reliability of the transmission.

[0027] In this specific embodiment, the toothed pattern 9 is a straight tooth structure distributed along the circumference of the cylinder; the inner surface of the toothed belt 10 is provided with tooth grooves that mesh with the straight tooth structure.

[0028] The toothed pattern 9 is machined into circumferential straight teeth on the bottom surface of the A / B threaded cylinder. The toothed belt 10's inner tooth groove precisely meshes with it to transmit torque. The straight tooth structure of the toothed pattern 9 and the toothed belt 10 mesh to prevent synchronization deviation.

[0029] In this specific embodiment, the bottom surface of platform 11 is welded and fixed to the top end of threaded rod A 6, and the bottom surface of platform 11 is welded and fixed to the top end of threaded rod B 8.

[0030] The bottom of platform 11 is welded to the top of threaded rod 6 around the entire circumference, and simultaneously welded to the top of threaded rod 8 around the entire circumference to form an integral load-bearing structure. The welded and fixed threaded rods 6 and 8 resist heavy load impact deformation.

[0031] In this specific embodiment, a first telescopic rod 12 is vertically arranged on both sides of the top of the fixing block 3, and a second telescopic rod 13 is vertically arranged on both sides of the top of the box 2. The top ends of the first telescopic rod 12 and the second telescopic rod 13 are both fixedly connected to the bottom surface of the platform 11.

[0032] The first telescopic rod 12 on the top of the fixed block 3 and the second telescopic rod 13 on the top of the box 2 are installed vertically and their top ends are welded and fixed to the four corners of the bottom surface of the platform 11. The first telescopic rod 12 and the second telescopic rod 13 distributed at the four corners form an anti-tilting and stable frame.

[0033] In this specific embodiment, the threads of threaded screw A 6 and threaded screw B 8 have the same direction of rotation, and the internal threads of threaded cylinder A 5 and threaded cylinder B 7 have the same direction of rotation.

[0034] The A-threaded screw 6 and the A-threaded cylinder 5 adopt a right-hand threaded pair, and the B-threaded screw 8 and the B-threaded cylinder 7 are matched with a right-hand threaded pair. The A / B threaded pairs with the same direction of rotation ensure that the dual driving torque is in the same direction, thus improving energy efficiency.

[0035] Working principle: The drive motor 4 drives the A threaded cylinder 5 to rotate, and the toothed groove 9 at its bottom engages with the toothed belt 10 to drive the B threaded cylinder 7 to rotate synchronously. This causes the A threaded screw 6 and B threaded screw 8, which are in the same direction of rotation, to rise and fall vertically under the side effect of the threads, pushing the platform 11 to rise or fall. At the same time, the first telescopic rod 12 of the fixed block 3 and the second telescopic rod 13 of the box 2 extend and retract synchronously to support the four corners of the platform 11 and maintain the stability of the lifting process.

[0036] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
