Description

Technical Field

[0001] The present invention relates to the technical field of solar panel mounting brackets, and in particular to a solar panel mounting bracket. Background Art

[0002] Solar panels, also known as photovoltaic panels, are devices that convert solar energy into electricity. Their core is composed of multiple photovoltaic cells (typically made of silicon-based materials). Through the photovoltaic effect, they convert sunlight directly into direct current (DC) electricity, which can be used to power homes, industries, or public facilities. They can also be combined with batteries to store electricity (e.g., in off-grid systems). They can also replace fossil fuels and reduce environmental pollution.

[0003] Solar panels are usually installed on the ground or on rooftops, but in some special cases, such as in urban areas with dense high-rise buildings where ground space is limited, in mountainous or watery areas, or for specific functional requirements (such as communication and monitoring), they need to be installed on the top of a tower using high-altitude brackets.

[0004] At present, the installation of solar panels on high towers mainly adopts high-altitude hoisting, combined with manual fixation and manual posture adjustment operation mode. The pre-assembled solar panel brackets are lifted to the designed height of the tower using lifting equipment. The operators climb at high altitude or use lifting platforms to tighten the bolts between the brackets and the tower body, and manually adjust the deployment angle of the solar panels to make the solar panels reach the preset inclination angle to improve the light receiving efficiency.

[0005] In this operation mode, high-altitude manual work requires the use of climbing or hanging equipment. In strong wind environments, the shaking of the installation bracket causes the installation accuracy to be out of control, increasing the risk of human operation. At the same time, manual adjustment of the deployment angle of the solar panels depends on experience, and there is a certain positioning error, which affects the subsequent power generation efficiency.

[0006] Based on the above situation, there is an urgent need for a solar panel mounting bracket that can complete the integrated assembly of the mounting bracket and solar panels on the ground, and realize the deployment of solar panels through mechanical linkage to reduce the amount of high-altitude work.

[0013] Preferably, a guide plate is fixed on the mounting frame, a telescopic part is fixed on the guide plate, a handle is keyed on the output shaft of the telescopic part, a locking plate is slidably connected to the guide plate, and both left and right ends of the locking plate are provided with equidistantly distributed limiting teeth, and both left and right ends of the guide plate are fixed with short rods, and both ends of the locking plate are slidably connected to the adjacent short rods, and a return spring wrapped around the short rod is compressed between the locking plate and the guide plate.

[0014] Preferably, two symmetrically distributed sliding members are slidably connected to the mounting frame, and a slider is fixed to each of the sliding members. The slider is slidably connected to the adjacent positioning plate and guide plate, and the slider is hinged to the handle through a connecting rod.

[0015] Preferably, each of the sliding members is fixed with a limiting member, and the end of the limiting member is processed into a V shape.

[0017] Beneficial effect: Compared with the existing technology, the device completes the initial fixed connection between the device and the tower body by pulling the hook until the hook and the tower body form a rigid lock. According to the preset parameters and the scale markings on the indicator plate, the adjustment part is slid to the target position, and the screw is rotated so that its end is pressed against the second wire rope to form a friction brake.

[0019] Through the elastic wedge-shaped correction group, when the V-shaped end of the limiting piece is misaligned with the center line of the tower body, the wedge block is squeezed by the tower body, and the wedge block is pressed and slides to avoid the position, and the compression spring is deformed. As the device is adjusted, the V-shaped end of the limiting piece is gradually aligned with the center line of the tower body. At this time, the wedge block is not pressed. Under the action of the compression spring, the wedge block resets and moves, and the V-shaped end of the limiting piece is locked with the tower body. Compared with the traditional manual adjustment method, the device achieves the effect of automatic compensation under installation deviation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Next, combine Figure 1-Figure 7 A specific embodiment of the present invention is described in detail.

[0029] refer to Figure 1 and Figure 2 The yoke 21 is connected to the tower body by a screw thread 24, and the yoke 21 is connected to the tower body by a screw thread 25. The yoke 21 is connected to the tower body by a screw thread 26, and the yoke 21 is connected to the tower body by a screw thread 27.

[0030] The core of this device is to accurately control the inclination angle of the mast 10 through mechanical linkage in a high-altitude environment, thereby optimizing the light-receiving efficiency of the solar panels. Therefore, a control component is designed to cooperate to achieve this. Specifically, a rotating shaft 111 is connected to the left side of the bottom of the mounting frame 1, which is the core transmission component. The end key of the rotating shaft 111 is connected to the worm gear 3. The rotating shaft 111 is fixedly connected to the mast 10 on the left. The flipping action of the mast 10 depends on the rotation of the rotating shaft 111, and the rotation of the rotating shaft 111 depends on the rotation of the worm gear 3.

[0031] refer to Figure 5 In order to realize the rotation of the worm gear 3, a guide frame 32 is fixed to the positioning column 2 on the left side, and a rotating rod 39 is connected to the guide frame 32. The front section of the rotating rod 39 is processed into a worm 31, and the rear section of the rotating rod 39 is wound with a wire rope 33. The worm 31 is engaged with the worm wheel 3 to realize the rotation of the rotating shaft 111.

[0032] refer to Figure 4 The positioning column 2 is a hollow column, and a hook 21 is slidably connected to the top of the positioning column 2. The bottom of the inner cavity of the positioning column 2 is fixedly connected to a fixing column 24, and a fixing ring 23 is sleeved on the fixing column 24. The fixing ring 23 and the hook 21 are connected by a wire rope 211. The wire rope 211 has a certain length. The inner cavity of the positioning column 2 is fixedly connected to a wire box 22, and the wire rope 211 is accommodated in the wire box 22. The end of the wire rope 211 passes through the wire box 22 and is fixed to the fixing ring 23. The wire rope 211, the fixing column 24, the wire rope 211 and the fixing ring 23 are all built into the inner cavity of the positioning column 2. External force pulls the hook 21 and fixes it to the tower body. The wire rope 211 is stretched, and the initial stable connection between the device and the tower body is achieved through the connection of the fixing ring 23, the hook 21 and the wire rope 211.

[0033] refer to Figure 5 A connecting frame 34 is fixedly connected to the side wall of the hook 21, and the connecting frame 34 moves with the hook 21. An indicator plate 341 is fixedly connected to the side wall of the connecting frame 34, and a scale is marked on the indicator plate 341. The indicator plate 341 moves with the connecting frame 34. The free end of the wire rope 2 33 is fixedly connected to the top of the indicator plate 341, and the wire rope 2 33 moves with the indicator plate 341. The fixed end of the wire rope 2 33 is fixedly connected and wound around the rear end of the rotating rod 39. As the wire rope 2 33 is stretched, the rotating rod 39 is controlled to rotate, and then the worm 31 engages with the worm wheel 3 to realize the rotation of the rotating shaft 111.

[0034] refer to Figure 6In order to achieve precise control of the inclination angle of the mast 10 to optimize the light receiving efficiency of the solar panel, an adjusting member 35 is slidably connected to the connecting frame 34, and a blocking block 38 is fixed to the adjusting member 35. The second steel wire rope 33 passes through the blocking block 38 and the adjusting member 35 in the longitudinal direction in sequence. A screw 36 is threadedly connected to the adjusting member 35, and the screw 36 passes through the adjusting member 35 and extends to the inner cavity locking position of the blocking block 38. The radial pressing force is generated by the axial displacement of the screw 36 to achieve friction locking of the second steel wire rope 33.

[0035] refer to Figure 6 A latch 37 is fixed to the screw 36, and an array of equally spaced pin holes 342 are opened on the side wall of the indicator plate 341. The spacing of the pin holes 342 matches the inclination adjustment resolution of the mast 10. The pin holes 342 and the latch 37 are locked together to maintain the locking state of the screw 36 and the wire rope 33, avoiding accidental loosening due to vibration or load changes, and ultimately achieving long-term stable maintenance of the inclination angle of the mast 10.

[0036] When the device is transported to the target height of the tower by hoisting equipment, external force is applied to pull the hook 21, and the wire rope 211 is extended until the hook 21 is rigidly locked with the tower structure, completing the initial fixed connection between the device and the tower.

[0037] Subsequently, according to the preset parameters and the scale markings on the indicator plate 341, the adjusting member 35 is slid axially along the connecting frame 34 to the target position, and the screw 36 is rotated so that its end is pressed against the wire rope 2 33 to form a friction brake. At the same time, the pin 37 on the screw 36 is embedded in the corresponding pin hole 342 on the indicator plate 341, and the screw 36 is maintained fixed through mechanical interlocking. After locking, the wire rope 2 33 is divided into two independent acting sections, upper and lower.

[0038] The upper part of the wire rope 23 maintains the initial locking state between the device and the tower body through the hook 21, and the lower part of the wire rope 23 applies tension to drive the rotating rod 39 to rotate, so that the worm 31 engages with the worm wheel 3, the rotating shaft 111 rotates, and the mast 10 is linked to rotate, and finally the solar panel mounted on the mast 10 reaches a preset inclination angle. This angle can be maximized through preliminary calculation to capture incident light, thereby improving the overall photoelectric conversion performance.

[0039] In the above, the operator only needs to pull the hook 21 in one direction to complete the initial locking of the device and the tower body, and according to the assembly height and orientation parameters, move the adjustment part 35 to the corresponding scale position of the indicator plate 341, tighten the screw 36 to lock the pin 37 with the pin hole 342, so as to adjust the length of the lower part of the wire rope 33, and then adjust the number of rotations of the turning rod 39, thereby adjusting the number of meshing circles of the worm 31 and the worm wheel 3, and finally achieve the effect of adjusting the flipping angle of the mast 10, effectively simplifying the operating steps, and replacing manual experience judgment with geometric parameters and mechanical hard limits to simplify the adjustment of complex angles at high altitudes, effectively reducing the labor intensity and operating errors of manual adjustment during high-altitude operations, and improving the degree of automation and reliability of the device.

[0040] refer to Figure 2 The support frame 11 is fixed with a guide plate 11, and a telescopic member 18 is fixed on the guide plate 11. The output shaft of the telescopic member 18 is keyed to a handle 17. The guide plate 11 is slidably connected to a positioning plate 12, and the left and right ends of the positioning plate 12 are provided with equidistantly distributed limiting teeth. The left and right ends of the guide plate 11 are fixed with short rods 101, and the two ends of the positioning plate 12 are slidably connected to the adjacent short rods 101 to form a sliding guide. A return spring 121 wound on the short rod 101 is compressed between the positioning plate 12 and the guide plate 11. The positioning plate 12 achieves an up and down movement effect under the limit of the guide plate 11, and the return spring 121 is a reset energy storage for the positioning plate 12.

[0041] Two symmetrically distributed sliding members 102 are slidably connected to the mounting frame 1, and a slider 103 is fixed to each of the sliding members 102. The slider 103 is slidably connected to the adjacent positioning plate 12 and the guide plate 11. The movement trajectory of the slider 103 is constrained by the limiting teeth of the positioning plate 12. The serrated structure design of the limiting teeth enables the slider 103 to slide only radially outward and cannot be reset in the reverse direction under normal circumstances, forming a mechanical one-way self-locking. The slider 103 and the handle 17 are hinged by a connecting rod 16.

[0042] In order to improve the contact stiffness and installation stability between the device and the tower body, a limiting member 13 is fixed to each of the sliding members 102. The end of the limiting member 13 is processed into a V shape. The V-shaped design of the end of the limiting member 13 is intended to position the tower body and enhance the installation stability of the device.

[0043] The operator pulls up the handle 17, and the telescopic end of the telescopic member 18 extends. Under the transmission of the connecting rod 16, the two sliders 103 move toward each other, linking the two sliding members 102 to move closer to each other, and the two limiting members 13 to move closer to each other, that is, the device is in the storage state.

[0044] After the device reaches the target height, the device is initially locked with the tower body by towing the hook 21. According to the assembly height and orientation parameters, the adjustment member 35 is moved to the corresponding scale position of the indicator plate 341, and the screw 36 is tightened to lock the pin 37 with the pin hole 342, so as to achieve the effect of adjusting the length of the lower section of the wire rope 33 and the flipping angle of the mast 10, so that the solar panel installed on the mast 10 reaches the preset inclination angle.

[0045] When the lever 17 is in the closed position, the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members 13 are in the closed position, and the two limit members

[0046] When disassembling, press the handle 17 downward again, and the two sliders 103 move downward in linkage, squeezing the limiting teeth of the positioning plate 12. The positioning plate 12 moves downward under pressure, and the limiting teeth and the slider 103 are unlocked. Slide the two sliders 103 to move the two limiting members 13 toward each other and close together, thereby releasing the lock from the tower body and removing the handle 17. In this way, the device can be separated from the tower body.

[0047] refer to Figure 1 This device adopts an elastic wedge-shaped correction component to solve the problem of deviation in the initial installation. The ends of the limiting member 13 are slidably connected with a U-shaped frame 104, and two symmetrically distributed wedge blocks 14 are slidably connected on the U-shaped frame 104. The wedge blocks 14 are distributed at the V-shaped ends of the limiting member 13, and a compression spring 15 wrapped around the U-shaped frame 104 is compressed between the wedge blocks 14 and the limiting member 13.

[0048] Taking into account that the device may be displaced and tilted during the hoisting process or the initial installation process, at this time, the V-shaped end of the limiting member 13 is misaligned with the center line of the tower body, that is, the wedge block 14 contacts the tower body on one side. At this time, through the squeezing of the wedge block 14 and the tower body, the wedge block 14 is pressed and slides to avoid position, and the compression spring 15 is deformed. As the device is adjusted, the V-shaped end of the limiting member 13 is gradually aligned with the center line of the tower body. At this time, the wedge block 14 is not pressed. Under the action of the compression spring 15, the wedge block 14 is reset and moved, and the V-shaped end of the limiting member 13 is locked with the tower body. Compared with the traditional manual adjustment method, the device can achieve the effect of automatic compensation under installation deviation.

[0049] In summary, the present device completes the preliminary fixed connection between the present device and the tower body by pulling the hook 21 until the hook 21 forms a rigid lock with the tower structure, and then slides the adjustment member 35 to the target position according to the preset parameters and the scale mark of the indicator plate 341, and rotates the screw 36 so that its end is pressed against the wire rope 2 33 to form a friction brake. At the same time, the pin 37 on the screw 36 is embedded in the corresponding pin hole 342 of the indicator plate 341, and the fixation of the screw 36 is maintained by mechanical interlocking. The rotating rod 39 is driven to rotate by the wire rope 2 33, and then the worm 31 is engaged with the worm gear 3, the rotating shaft 111 rotates, and the mast 10 is linked to rotate, and finally the solar panel mounted on the mast 10 reaches the preset inclination angle, maximizing the incident light capture efficiency, thereby improving the overall photoelectric conversion performance. The advantage is that it can effectively simplify the operation steps, replace manual experience judgment with geometric parameters and mechanical hard limits, simplify the adjustment of complex angles at high altitudes, effectively reduce the labor intensity and operation error of manual adjustment during high-altitude operations, and improve the automation and reliability of the present device.

[0050] By pressing the handle 17 downward, under the transmission of the connecting rod 16, the two sliders 103 move downward and backward, the positioning plate 12 and the two sliding members 102 move in a controlled manner, and the two limiting members 13 move backward and separate in a controlled manner and contact and engage with the tower body fulcrum. Under the constraint of the limiting teeth of the positioning plate 12, the two limiting members 13 are locked on the tower body, realizing a fast and reliable connection between the high-altitude equipment of this device and the tower body.

[0051] Through the elastic wedge-shaped correction group, when the V-shaped end of the limiting member 13 is misaligned with the center line of the tower body, the wedge block 14 is squeezed by the tower body, and the wedge block 14 is pressed and slides to avoid the position, and the compression spring 15 is deformed. As the device is adjusted, the V-shaped end of the limiting member 13 is gradually aligned with the center line of the tower body. At this time, the wedge block 14 is not pressed. Under the action of the compression spring 15, the wedge block 14 is reset and moved, and the V-shaped end of the limiting member 13 is locked with the tower body. Compared with the traditional manual adjustment method, the device achieves the effect of automatic compensation under installation deviation.

[0052] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
