Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module hoisting and clamping technology, specifically a photovoltaic module hoisting and clamping device. Background Technology

[0002] When installing photovoltaic (PV) panels and other PV modules in remote mountainous areas, it is inconvenient to transport the panels by vehicle. Drones are typically used for hoisting and transporting the panels. Chinese utility model patent CN221116654U discloses a special cable for drone hoisting of PV panels in mountainous PV power stations. Interlocking anti-rotation chain blocks prevent the cable from rotating, thus ensuring the stability of the PV panels during hoisting and aerial transport. However, in this method, the hoisting mechanism only clamps the four corners of the PV panel, leaving the center without upward support. Therefore, during hoisting and aerial transport, the center of the PV panel is prone to deformation. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a photovoltaic module hoisting and clamping device that can provide upward support to the center of the photovoltaic panel during hoisting and aerial transportation, thereby preventing deformation of the center of the photovoltaic panel.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A photovoltaic module hoisting and clamping device includes a rectangular mounting frame, a sliding frame, a clamping component, and a limiting component. There are two sliding frames, which are slidably arranged at intervals on two opposite sides of the mounting frame. The inner sides of the two sliding frames are each fixedly and at intervals with staggered comb plates for supporting the middle part of the photovoltaic module. The clamping component for clamping the photovoltaic module is fixedly arranged on the upper surface of the sliding frame. The upper surface of the clamping component is fixedly arranged with a hoisting component. The limiting component for keeping the position of the two sliding frames relatively constant is arranged between the mounting frame and the sliding frames.

[0005] As a limitation of this utility model: the limiting component includes a bidirectional screw for causing the two sliding frames to move in opposite directions and a rotating wheel for causing the bidirectional screw to rotate. The bidirectional screw is coaxially threaded through the lower part of the two sliding frames, and the two ends of the bidirectional screw are provided on the two opposite sides of the mounting frame. The rotating wheel is fixedly provided at one end of the bidirectional screw.

[0006] As a limitation of this utility model: a number of limiting grooves with an axial length less than the axial length of the rotating wheel are evenly spaced on the arc surface of the rotating wheel; the end face of the rotating wheel away from the bidirectional screw is evenly spaced with the same number of end face grooves as the limiting grooves and corresponding to the limiting grooves in position; the depth of the end face grooves is greater than the depth of the limiting grooves; a fixing block is fixedly installed on the upper surface of the mounting frame near the rotating wheel, and the fixing block is located directly above the bidirectional screw; a crank rod for being placed in both the limiting grooves and the end face grooves passes through the fixing block.

[0007] As a limitation of this utility model: the crank includes a rod body and a limiting part. The rod body is a cylinder that passes through the middle of the fixing block. The shape of the inner wall of the limiting groove is adapted to the shape of the outer wall of the rod body. The limiting part is fixedly installed on the rod body at one end near the rotating wheel. The cross-sectional shape of the limiting part is arched, and the height of the arch is greater than the diameter of the rod body. The shape of the inner wall of the end face groove is adapted to the shape of the outer wall of the limiting part.

[0008] As a limitation of this utility model: a cylindrical baffle with a diameter larger than the diameter of the rod body is fixedly provided at the end of the crank away from the rotating wheel. A spring sleeved on the rod body is also provided between the baffle and the fixed block. The length of the spring in the free state is the same as the distance between the baffle and the fixed block. The diameter of the spring is smaller than the diameter of the baffle. The two ends of the spring abut against the surface of the fixed block away from the rotating wheel and the surface of the baffle close to the rotating wheel, respectively.

[0009] As a limitation of this utility model: the clamping assembly includes a clamping block that opens toward the inside of the sliding frame. The clamping block includes a vertical part and a horizontal part. The vertical part is fixedly connected to the upper surface of the sliding frame, and the horizontal part is fixedly connected to the top of the vertical part.

[0010] As a limitation of this utility model: the clamping assembly further includes a fixed plate, a switching screw, and a clamping plate. The fixed plate is fixedly disposed on the upper surface of the clamping block, the lifting component is fixedly disposed on the upper surface of the fixed plate, the switching screw passes through the middle of the fixed plate, and a nut is also sleeved on one end of the switching screw located inside the sliding frame. The two sides of the switching screw also have guide rods passing through the fixed plate, and the clamping plate is simultaneously fixedly disposed on one end of the two guide rods located inside the sliding frame.

[0011] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: by fixing comb plates that can overlap with each other on the inner side of the two sliding frames, and threading bidirectional screws through the lower part of the two sliding frames, after turning the bidirectional screws, the two sets of comb plates can be brought closer to each other and overlapped to form a plane for supporting the photovoltaic panel. During the hoisting and aerial transportation of the photovoltaic panel, an upward supporting force is provided to the middle of the photovoltaic panel, avoiding deformation of the middle of the photovoltaic panel.

[0012] Meanwhile, a limiting groove and an end face groove of different depths are opened on the rotating wheel fixed at one end of the bidirectional screw, and the crank is placed in the limiting groove and the end face groove at the same time. This can further limit the position of the rotating wheel and keep the relative position between the two sliding frames constant during the hoisting and aerial transportation of photovoltaic panels.

[0013] In addition, for narrow photovoltaic modules, the two clamping plates can be brought closer together by turning the switching screw, thereby enabling the clamping of photovoltaic modules of different sizes. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the photovoltaic module hoisting and clamping device described herein is a preferred embodiment and is only used for illustration and explanation of the present invention, and does not constitute a limitation thereof.

[0021] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0022] A photovoltaic module hoisting and clamping device, such as Figure 1 and Figure 2As shown, the system includes a rectangular mounting frame 1, sliding brackets 2, and clamping components. There are two sliding brackets 2, which are spaced apart and parallel to each other on opposite sides of the mounting frame 1. Both sliding brackets 2 are capable of horizontal movement along the mounting frame 1. Figure 1 and Figure 2 In the middle, the side of one sliding frame 2 that is closer to the other sliding frame 2 is the inner side, and correspondingly, the side of the other sliding frame 2 that is closer to one of the sliding frames 2 is the inner side.

[0023] Both sliding frames 2 have staggered, parallel, fixed comb plates 3 on their inner sides to support the center of the photovoltaic module. Each tooth in the comb plate 3 is a rectangular strip. When the two sliding frames 2 approach each other, the teeth of one set of comb plates 3 gradually move into the gap between adjacent teeth of the other set of comb plates 3. Therefore, when the two sliding frames 2 are close together, the staggered comb teeth form a plane to support the photovoltaic module, providing upward support to the center of the photovoltaic panel during hoisting and aerial transport, preventing deformation of the photovoltaic panel due to lack of support in the center.

[0024] A clamping assembly for holding photovoltaic modules is fixedly installed on the upper surface of the sliding frame 2, and a lifting component 4 is fixedly installed on the upper surface of the clamping assembly to facilitate the lifting mechanism to lift the entire device. The clamping assembly includes a clamping block 5, a fixing plate 6, a switching screw 7, and a clamping plate 8. The clamping block 5 is a right-angled groove that opens towards the inside of the sliding frame 2, and the clamping block 5 is fixedly installed on the upper surface of the sliding frame 2. The clamping block 5 includes a vertical part and a horizontal part. The vertical part is fixedly connected to the upper surface of the sliding frame 2, and the horizontal part is fixedly connected to the top of the vertical part. A gap is formed between the horizontal part and the comb teeth to accommodate the side of the photovoltaic module, so that the two opposite sides of the photovoltaic panel are respectively clamped in the two clamping blocks 5.

[0025] The fixing plate 6 is a rectangular plate structure, which is fixedly mounted on the upper surface of the horizontal portion of the clamping block 5. A switching screw 7 passes through the middle of the fixing plate 6, and guide rods 18 are mounted on both sides of the fixing plate 6 and the switching screw 7. On the same sliding frame 2, a rectangular plate clamping plate 8 is fixedly mounted at one end of each guide rod 18 located inside the sliding frame 2. The guide rods 18 are used to keep the clamping plate 8 parallel to the surface of the fixing plate 6 located inside the sliding frame 2 when it moves inward. A nut is also fitted onto the end of the switching screw 7 located inside the sliding frame 2 to limit the movement of the switching screw 7.

[0026] When it is necessary to clamp photovoltaic modules whose width is less than the length of the comb teeth, such as photovoltaic brackets, the end of the switching screw 7 away from the clamping plate 8 can be turned to move the switching screw 7 inward towards the sliding frame 2 and press against the surface of the clamping plate 8 near the guide rod 18, thus moving the clamping plate 8 inward towards the sliding frame 2. Figure 3As shown, when the clamping plate 8 moves to the appropriate position, the nut is tightened to make it fit tightly against the side wall of the fixing plate 6 near the clamping plate 8, thus fixing the position of the switching screw 7 and preventing the clamping plate 8 from moving closer to the fixing plate 6, so as to clamp the photovoltaic bracket between the two clamping plates 8, thereby realizing the clamping of photovoltaic modules of different sizes.

[0027] The lifting component 4 is fixedly mounted on the upper surface of the fixed plate 6. In this embodiment, the lifting component 4 is a lifting lug, which is a rectangular block with a through hole in the middle, which facilitates the lifting mechanism to lift the entire device. There are two lifting components 4 on each fixed plate 6, forming a four-point lifting structure, which further improves the stability of the photovoltaic panel during lifting and aerial transportation.

[0028] The photovoltaic module hoisting and clamping device also includes a limiting component for keeping the positions of the two sliding frames 2 relatively constant. The limiting component is disposed between the mounting frame 1 and the sliding frames 2. The limiting component includes a bidirectional screw 9 for moving the two sliding frames 2 in opposite directions and a rotating wheel 10 for rotating the bidirectional screw 9. The bidirectional screw 9 is coaxially threaded through the lower part of the two sliding frames 2, and its two ends are disposed on two opposite sides of the mounting frame 1. The rotating wheel 10 is fixedly disposed at one end of the bidirectional screw 9. By turning the rotating wheel 10, the two sliding frames 2 can be moved closer or further away from each other along the mounting frame 1.

[0029] like Figure 4 As shown, a plurality of limiting grooves 11 with axial lengths less than the axial length of the rotating wheel 10 are evenly spaced on the arc surface of the rotating wheel 10. End face grooves 12, the same number as the limiting grooves 11 and corresponding in position to the limiting grooves 11, are evenly spaced on the circumferential side of the end face of the rotating wheel 10 on the side away from the bidirectional screw 9. The depth of the end face grooves 12 is greater than the depth of the limiting grooves 11, and the sum of the axial lengths of the limiting grooves 11 and the end face grooves 12 is the same as the axial length of the rotating wheel 10. Therefore, a plurality of right-angled through grooves are formed on the circumference of the rotating wheel 10.

[0030] A rectangular fixing block 13 is fixedly installed on the upper surface of the mounting frame 1 near the rotating wheel 10, and the fixing block 13 is located directly above the bidirectional screw 9. A crank is inserted in the fixing block 13 for simultaneous placement in the limiting groove 11 and the end face groove 12, that is, the crank can engage with the limiting groove 11 and the end face groove 12 at the same time, preventing the rotating wheel 10 from rotating accidentally, and further preventing the bidirectional screw 9 from driving the sliding frame 2 to move.

[0031] The crank includes a crank body 14 and a limiting part 15. The crank body 14 is a cylinder that passes through the middle of the fixing block 13. By pulling the end of the crank body 14 near the rotating wheel 10, the crank can move linearly in a direction parallel to the axial direction of the rotating wheel 10. The inner wall shape of the limiting groove 11 is adapted to the outer wall shape of the crank body 14, that is, the inner wall shape of the limiting groove 11 is an arc surface that can accommodate the crank body 14. The limiting part 15 is fixedly installed on the end of the crank body 14 near the rotating wheel 10. The cross-sectional shape of the limiting part 15 is arched, the height of the arch is greater than the diameter of the crank body 14, and the angles between the two opposite side walls and the bottom wall of the limiting part 15 are all right angles. The inner wall shape of the end face groove 12 is adapted to the outer wall shape of the limiting part 15, that is, each surface of the inner wall of the end face groove 12 is a mutually perpendicular plane that can accommodate the limiting part 15.

[0032] A cylindrical baffle 16 with a diameter larger than that of the rod body 14 is fixedly installed at the end of the crank away from the rotating wheel 10. A spring 17 is sleeved on the rod body 14 between the baffle 16 and the fixing block 13. The length of the spring 17 in its free state is the same as the distance between the baffle 16 and the fixing block 13. The diameter of the spring 17 is smaller than that of the baffle 16, and the two ends of the spring 17 abut against the surface of the fixing block 13 away from the rotating wheel 10 and the surface of the baffle 16 near the rotating wheel 10, respectively, thereby restricting the range of motion of the spring 17 between the baffle 16 and the rod body 14.

[0033] When the baffle 16 is pushed in the direction close to the rotating wheel 10 and the limiting part 15 is placed in the end face groove 12, the spring 17 is in a compressed state, which can provide a pulling force to the limiting part 15 in the direction away from the rotating wheel 10. Therefore, the limiting part 15 can fit tightly against the vertical side wall of the end face groove 12, thereby fixing the crank in the through groove formed by the limiting groove 11 and the end face groove 12, preventing the rotating wheel 10 from rotating unexpectedly due to the influence of other factors, and further ensuring the relative constancy of the position between the two sliding frames 2.

[0034] In this embodiment, first push the baffle 16 towards the rotating wheel 10, and prevent the crank from contacting the rotating wheel 10 to remove the limiting effect on the rotating wheel 10. Twist the rotating wheel 10 to make the bidirectional screw 9 drive the two sliding frames 2 away from each other, so as to move the two sets of comb plates 3 away from each other. Place the photovoltaic panel back-side down on the comb plate 3. Then, still preventing the crank from contacting the rotating wheel 10, twist the rotating wheel 10 in the opposite direction to make the bidirectional screw 9 drive the comb plates 3 on the two sliding frames 2 closer to each other. When the two sides of the photovoltaic panel gradually extend into the clamping block 5, stop twisting the rotating wheel 10 to complete the clamping of the photovoltaic panel. At the same time, a structure is formed in which the upper surface of the comb plate 3 supports the middle of the photovoltaic panel. Finally, place the crank in the through groove formed by the limiting groove 11 and the end face groove 12, so that the crank engages with the limiting groove 11 and the end face groove 12 at the same time to limit the rotating wheel 10.

[0035] For photovoltaic modules whose width is less than the length of the comb plate 3, such as photovoltaic brackets, even after the two sets of comb plates 3 are fully overlapped, it is still impossible to position both sides of the photovoltaic bracket within the clamping blocks 5. In this case, it is necessary to turn the switching screw 7 to move it inward toward the sliding frame 2 until it abuts against the clamping plate 8. After the switching screw 7 abuts against and pushes the clamping plate 8 inward toward the sliding frame 2 to a suitable position, the nut fitted on the switching screw 7 is used to limit the movement of the switching screw 7. Therefore, by adjusting the relative position between the two clamping plates 8, the photovoltaic bracket is clamped.
