Description

Technical Field

[0001] This utility model relates to the field of special equipment transfer technology, and in particular to a transfer device for photovoltaic panels of various sizes. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect of photovoltaic panels. During the construction of photovoltaic power plants, transfer devices are frequently needed to move the photovoltaic panels. Existing technology includes a photovoltaic panel transfer device, such as the one provided in patent publication number CN220595606U, which includes photovoltaic panel slots arranged at equal intervals and a support clamping assembly at the bottom of the photovoltaic panel slots. This device can be used to transfer photovoltaic panels of a fixed size. Its operation involves: inserting the photovoltaic panel into the photovoltaic panel slot, and then effectively clamping the photovoltaic panel using the support clamping assembly at the bottom to fix the photovoltaic panel and ensure its stability during transfer.

[0003] Because the spacing between photovoltaic panel slots and the dimensions of the configured load-bearing clamping components are fixed, this system is typically only suitable for clamping and transporting photovoltaic panels of a certain standard size, and cannot transport photovoltaic panels of non-fixed sizes. If the size is too large, it will be impossible to insert or clamp; if the size is too small, it will be easy to clamp unstablely and cause shaking. Utility Model Content

[0004] To address the aforementioned technical problems in the existing technology, this utility model aims to provide a device for transporting photovoltaic panels of non-fixed sizes.

[0005] Specifically, this utility model provides a transfer device for photovoltaic panels of various sizes, including a U-shaped carriage surrounded by a bottom plate, a left side plate, and a right side plate; It also includes multiple protective partitions, a left connecting rope, a right connecting rope, a left fixing device, and a right fixing device; Both the left and right side plates are provided with horizontally penetrating rectangular limiting grooves; The protective partition is vertically installed inside the U-shaped carriage, and each side is provided with a first limiting slider that passes through a rectangular limiting groove; the part of the first limiting slider that passes through the U-shaped carriage has a horizontal perforation; One end of the right connecting rope is connected to the right fixing device, and the other end passes through all the holes on the right side of the U-shaped carriage in sequence and is connected to the limiting piece; the right fixing device is fixed to one end of the right side plate. The left and right connecting ropes are symmetrically arranged, and the left and right fixing devices are symmetrically arranged. The right and left fixing devices are used to tighten and lock the right and left connecting ropes to clamp the photovoltaic panels placed between the protective partitions.

[0006] Preferably, the right fixing device includes a threaded post, a retaining ring, and a limiting cap; The threaded post is fixed to one end of the right side plate; A retaining ring is fitted onto the threaded post to lock the right connecting rope; The limit cap has an internal thread and is used to lock the retaining ring with the threaded post.

[0007] Furthermore, it also includes the first side panel; The first side panel is parallel to the protective partition and is fitted around the end of the U-shaped carriage away from the left fixing device. A drive mechanism is provided between the first side plate and the adjacent protective partition; The drive structure includes two second limit sliders, two connecting rods rotatably connected at the midpoint, two third limit sliders, and a threaded rod; The second limiting slider is engaged in a groove provided on the adjacent protective partition; the third limiting slider is engaged in a groove provided on the inner wall of the first side plate. The two ends of the connecting rod are respectively hinged to the second limiting slider and the third limiting slider; The threaded rod passes through the threaded holes on the two second or third limit sliders, and the distance between the upper and lower sections of the reverse thread is adjusted to drive the protective partition to move horizontally. The major axis of the two grooves is in the same direction as the major axis of the threaded rod.

[0008] Furthermore, it also includes a handle fixed to the first side plate for pushing or pulling the transfer device.

[0009] Furthermore, this includes a second side panel and a handle; The second side panel is symmetrically arranged with the first side panel; The handle is fixed to the first or second side plate and is used to push or pull the transfer device.

[0010] Furthermore, it also includes at least one pair of connecting rods with a midpoint rotatable connection.

[0011] Furthermore, this includes a second side panel and a handle; The second side plate is parallel to the protective partition, and its two ends are respectively fitted and fixed to either end of the left side plate and either end of the right side plate. The handle is fixed to the second side plate and is used to push or pull the transfer device.

[0012] Furthermore, it also includes a buffer mechanism consisting of a buffer plate and a compression spring; The buffer plate is horizontally positioned above the base plate, and multiple compression springs are evenly distributed between the two. The buffer mechanism is used to reduce the contact stiffness between the photovoltaic panel and the base plate.

[0013] Furthermore, multiple balls are evenly embedded on the upper surface of the buffer plate.

[0014] Furthermore, it also includes a protective cover installed on the outside of the rectangular limiting slide groove.

[0015] Compared to existing technologies, the device provided by this invention allows the left and right connecting ropes to be loosened during loading, enabling all protective partitions to slide freely along the rectangular limiting groove. The photovoltaic panel to be transported is inserted between two protective partitions, and then the left and right connecting ropes are pulled simultaneously, causing all the protective partitions to be pressed towards one side of the transport device along the rectangular limiting groove, thus clamping all the inserted photovoltaic panels. Subsequently, the left and right connecting ropes are fixed by the left and right fixing devices respectively, keeping the photovoltaic panels in a clamped state to ensure their stability during transport. Clearly, the transport device can accommodate photovoltaic panels of different sizes, and can transport photovoltaic panels of non-fixed sizes. Attached Figure Description

Detailed Implementation

[0021] The technical solution provided by this utility model will be further described in detail below with reference to the embodiments and accompanying drawings.

[0022] Example: like Figure 1 , Figure 2As shown in the figure, this embodiment provides a transfer device that can transfer photovoltaic panels of various sizes. The transfer device includes a U-shaped carriage 1 and wheels 2, as well as multiple protective partitions 3, a left connecting rope 4, a right connecting rope 5, a left fixing device 6, and a right fixing device 7. The U-shaped carriage 1 is formed by a bottom plate 11, a left side plate 12, and a right side plate 13. Both the left side plate 12 and the right side plate 13 are provided with horizontally penetrating rectangular limiting grooves 8. The protective partitions 3 are vertically arranged inside the U-shaped carriage 1, and each side is provided with a first limiting slider 9 that extends out of the rectangular limiting groove 8. The portion of the first limiting slider 9 that extends out of the U-shaped carriage 1 is provided with a horizontal perforation. One end of the right connecting rope 5 is connected to the right fixing device 7, and the other end passes through all the perforations on the right side of the U-shaped carriage 1 in sequence before being limited. The right fixing device 7 is fixed to one end of the right side plate 13. The left connecting rope 4 and the right connecting rope 5 are arranged symmetrically, and the left fixing device 6 and the right fixing device 7 are arranged symmetrically. The right fixing device 7 and the left fixing device 6 are used to tighten and lock the right connecting rope 5 and the left connecting rope 4 to clamp the photovoltaic panels placed between the protective partitions 3.

[0023] The limiting component is specifically a limiting rod or a limiting ball, or it can be directly set as a rope joint, which can limit the right connecting rope 5 to one side of the perforation to prevent it from detaching. The limiting component can be used in conjunction with the right connecting rope 5 and the right fixing device 7 to connect all the protective partitions 3 in series, so as to achieve horizontal sliding in the length direction of the rectangular limiting groove 8.

[0024] During the transfer process, the photovoltaic panel to be transferred is placed between two adjacent protective partitions 3, the left connecting rope 4 and the right connecting rope 5 are tightened and locked simultaneously by the left fixing device 6 and the right fixing device 7 to clamp the photovoltaic panel for transfer.

[0025] As can be seen, this structure can adjust the distance between adjacent protective partitions by adjusting the rope pitch, thereby achieving stable clamping of photovoltaic panels of different sizes (with varying thicknesses and widths smaller than the width of the transfer device, i.e., any photovoltaic panel with a spacing between the left side panel 12 and the right side panel 13). Thus, even during the same transfer process, the distance between different adjacent protective partitions can be adjusted to simultaneously clamp photovoltaic panels of different sizes, meeting transfer needs in more scenarios and improving the transfer efficiency of photovoltaic panels.

[0026] Optionally, the right fixing device 7 includes a threaded post 71, a fixing ring 72, and a limiting cap 73; the threaded post 71 is fixed to one end of the right side plate 13; the fixing ring 72 is sleeved on the threaded post 71 and used to lock the right connecting rope 5; the limiting cap 73 is internally threaded and is used to cooperate with the threaded post 71 to lock the fixing ring 72.

[0027] Furthermore, such as Figure 3 , Figure 4 As shown, it also includes a first side plate 15 and a drive mechanism connected thereto. The drive mechanism includes a second limiting slider 21, a connecting rod 22, a third limiting slider 23, and a threaded rod 24.

[0028] The first side plate 15 is parallel to the protective partition 3 and is fitted around the end of the U-shaped carriage 1 away from the left fixing device 6. A driving mechanism is provided between the first side plate 15 and the adjacent protective partition 3. The driving structure includes a threaded rod 24, two second limiting sliders 21, two third limiting sliders 23, and a pair of connecting rods 22 rotatably connected at the midpoint. The second limiting sliders 21 are engaged with the sliding grooves provided on the adjacent protective partition 3. The third limiting sliders 23 are engaged with the sliding grooves provided on the inner wall of the first side plate 15. The two ends of the connecting rod 22 are respectively hinged to the second limiting sliders 21 and the third limiting sliders 23. The threaded rod 24 is vertically inserted through the threaded holes on the two second limiting sliders 21 (or the two third limiting sliders 23), and the threads on its upper and lower sections are opposite. By rotating the threaded rod 24, the two second limiting sliders 21 are brought closer to or further away from each other, thereby adjusting the tilt angle of the two connecting rods 22 and pushing or pulling the adjacent protective partition 3 of the first side plate 15 to move horizontally back and forth. If the threaded rod 24 passes vertically through the threaded holes on the two second limit sliders 21, the position of the threaded rod 24 remains unchanged; if the threaded rod 24 passes vertically through the threaded holes on the two third limit sliders 23, the position of the threaded rod 24 moves horizontally as the drive mechanism extends or retracts.

[0029] The major axes of the two sliding grooves are aligned with the major axis of the threaded rod 24 to ensure that the second limiting slider 21 and the third limiting slider 23 can slide synchronously. It should be noted that the major axis of the sliding groove on the inner wall of the first side plate 15 is the direction in which the third limiting slider 23 slides. This sliding groove can be arranged in any direction on the inner wall of the first side plate 15, and the sliding grooves on the adjacent protective partition 3 are positioned accordingly.

[0030] Optionally, a handle 16 fixed to the first side plate 15 is also included for pushing or pulling the transfer device.

[0031] Optionally, a second side plate 14 and a handle 16 are also included; the second side plate 14 is symmetrically arranged with the first side plate 15; the handle 16 is fixed to the first side plate 15 or the second side plate 14 and is used to push or pull the transfer device. The base plate 11, the left side plate 12, the right side plate 13, the second side plate 14 and the first side plate 15 form an upward-opening box structure. The box structure is more stable and can better ensure the safety of the photovoltaic panel transfer.

[0032] Optionally, it also includes at least one pair of connecting rods 22 with a midpoint rotatable connection. The hinge points of the multiple pairs of connecting rods 22 with the second limiting slider 21 are evenly distributed, and the hinge points with the third limiting slider 23 are also evenly distributed.

[0033] Optionally, a second side plate 14 and a handle 16 are also included. The second side plate 14 is parallel to the protective partition 3, and its two ends are respectively fitted and fixed to either end of the left side plate 12 and either end of the right side plate 13. The handle 16 is fixed to the second side plate 14 and is used to push or pull the transfer device. The handle 16 facilitates the operation of the transfer device by the transfer personnel and saves effort. If the second side plate 14 is not provided, the number of photovoltaic panels that can be clamped and transferred is one less than the number of protective partitions 3. If it is provided, the same number of photovoltaic panels as the number of protective partitions 3 can be clamped and transferred.

[0034] It is evident that after all the photovoltaic panels to be transferred are mounted on the transfer device, they need to be tightened by pulling the left connecting rope 4 and the right connecting rope 5, and then simultaneously locked by the left fixing device 6 and the right fixing device 7. However, simultaneously controlling the left connecting rope 4 and the right connecting rope 5 is quite difficult, so the photovoltaic panels are prone to uneven force during the tightening and locking process, resulting in damage to the photovoltaic panels or insufficient clamping. The drive mechanism can smoothly push the protective partition 3 to move horizontally until all photovoltaic panels are clamped and fixed. In this way, by tightening the left connecting rope 4 and the right connecting rope 5 and locking them by the left fixing device 6 and the right fixing device 7, damage to the photovoltaic panels or shaking and bumping caused by insufficient clamping can be avoided. At the same time, the space cleared by the drive mechanism on one side of the U-shaped carriage can be used to place other items or tools to be transferred.

[0035] Preferably, two or more pairs of connecting rods 22 with midpoint rotatable connections can further ensure the stability of the drive mechanism and help ensure that the photovoltaic panel is subjected to uniform force during the tightening and locking process.

[0036] Furthermore, it also includes a buffer mechanism consisting of a buffer plate 31 and compression springs 32; the buffer plate 31 is horizontally positioned above the base plate 11, and multiple compression springs 32 are evenly distributed between them; the buffer mechanism is used to reduce the contact stiffness between the photovoltaic panel and the base plate 11. The compression springs 32, in conjunction with the buffer plate 31, can buffer the placed photovoltaic panel, reducing the impact between the photovoltaic panel and the bottom of the transfer device.

[0037] Furthermore, multiple balls 33 are evenly embedded on the upper surface of the buffer plate 31, which can reduce the frictional resistance between the photovoltaic panel and the buffer plate 31 during the clamping process.

[0038] Furthermore, it also includes a protective cover 17 installed on the outside of the rectangular limiting slide 8 to prevent dust and debris from affecting the normal operation of the first limiting slider 9 and the left connecting rope 4 and the right connecting rope 5.

[0039] As can be seen from the above embodiments and accompanying drawings, compared with the prior art, the transfer device provided by this utility model allows the left and right connecting ropes to be loosened during loading, enabling all protective partitions to slide freely along the rectangular limiting groove. The photovoltaic panel to be transferred is inserted between two protective partitions, and then the left and right connecting ropes are pulled simultaneously, causing all the protective partitions to be pressed towards one side of the transfer device along the rectangular limiting groove, thus clamping all the inserted photovoltaic panels. Subsequently, the left and right connecting ropes are fixed by the left and right fixing devices respectively, keeping the photovoltaic panels in a clamped state to ensure the stability of the photovoltaic panels during transfer. Clearly, photovoltaic panels of different sizes can be inserted into the transfer device, and the transfer device can transfer photovoltaic panels of non-fixed sizes.

[0040] Furthermore, the box-type structure is more stable, which can better ensure the safety of photovoltaic panel transportation. The handle 16 facilitates the operation of the transportation device by the transportation personnel and saves effort. The drive mechanism smoothly pushes the protective partition 3 to move horizontally, avoiding damage to the photovoltaic panel or shaking and bumping due to insufficient clamping. Two or more scissor mechanisms help ensure that the photovoltaic panel is evenly stressed during the tightening and locking process. The compression spring 32, together with the buffer plate 31, can buffer the photovoltaic panel and reduce the impact between the photovoltaic panel and the bottom of the transportation device. The ball bearing 33 can reduce the frictional resistance between the photovoltaic panel and the buffer plate 31 during the clamping process.
