Description

Technical Field

[0001] This utility model relates to the field of photovoltaic engineering technology, and in particular to a photovoltaic cable laying device. Background Technology

[0002] A cable is a power or signal transmission device, usually composed of multiple conductors or groups of conductors. When used in photovoltaic projects, cables can transmit power and data. Cables used in photovoltaic projects are often wound on cable reels for subsequent transportation and use. When laying cables in photovoltaic projects, workers need to place the cable reels on the cable laying rack for cable laying.

[0003] Most current cable laying devices can only lay the cable coils flat, resulting in limited functionality and no ability to switch between flat and vertical laying. Due to the complexity of photovoltaic engineering sites, the angle of the cable reel is not fixed when unloading it from the loading vehicle. If the cable laying device cannot be adjusted according to actual needs, its adaptability is limited. Furthermore, current cable laying devices do not have the ability to fix cable reels of different sizes. Therefore, it is necessary to design a photovoltaic cable laying device. Utility Model Content

[0004] The main objective of this invention is to provide a photovoltaic cable laying device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A photovoltaic cable laying device includes a base plate and a support cylinder. A groove is formed in the middle of the upper surface of the base plate. A lead screw is rotatably connected to the inner wall of the groove. One end of the lead screw passes through the inner wall of the groove and extends to the outer surface of the base plate. A vertical plate is threadedly connected to the outer surface of the lead screw. A limiting groove is formed on one side of the upper surface of the base plate. The limiting groove is slidably connected to the vertical plate. A support rod is rotatably connected to the inner wall of the vertical plate. A movable plate is fixedly connected to the outer surface of the support rod. A positioning hole is formed on one side of the upper surface of the vertical plate. A high-strength bolt is movably connected to the inner bottom wall of the movable plate. The high-strength bolt is threadedly connected to the positioning hole. A top plate is fixedly connected to one side of the upper surface of the base plate.

[0007] To facilitate easy movement, in this photovoltaic cable laying device, one end of the lead screw is fixedly connected to a handle, a plug is inserted into one side of the handle, an insertion port is opened on one side of the top plate, a support leg is fixedly connected to the lower surface of the bottom plate, and a self-locking wheel is rotatably connected to the bottom end of the support leg.

[0008] In order to provide a flat support function, as a photovoltaic cable laying device of this utility model, the support cylinder is rotatably connected to the movable plate, and a support plate is rotatably connected to the outer surface of the movable plate near the support cylinder.

[0009] To achieve the rotational effect, in this photovoltaic cable laying device, one end of the support cylinder passes through one side of the movable plate and extends to the other side of the movable plate. A bidirectional threaded rod is rotatably connected to one side of the support cylinder, and a handle is fixedly connected to one end of the bidirectional threaded rod. A limit rod is inserted into one side of the handle.

[0010] In order to provide a limiting function, as a photovoltaic cable laying device of this utility model, a limiting hole is provided on the outer surface of the support cylinder near the throttle, and the size of the limiting hole is adapted to the size of the limiting rod.

[0011] In order to enable the function of adjusting the position of the slider, as a photovoltaic cable laying device of this utility model, the support cylinder has a hollow structure inside, and the outer surface of the support cylinder is provided with a movable groove. A slider is slidably connected inside the movable groove. There are two sliders and they are threadedly connected to a bidirectional threaded rod.

[0012] In order to achieve an expansion effect, as a photovoltaic cable laying device of this utility model, the outer surface of the slider is rotatably connected to a top rod, and one end of the top rod is rotatably connected to an expansion plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, through the arrangement of a lead screw, a vertical plate, a support rod, and a top plate, during use, the rotation effect of the support rod and the vertical plate allows the movable plate to flip. After the movable plate is rotated to a vertical angle, two sets of high-strength bolts are tightened into the positioning holes to securely fix the movable plate. At this time, the cable reel can be placed horizontally on the support cylinder for cable laying. If the cable reel needs to be placed vertically before fixing, the lead screw can be rotated to move the vertical plate to one side, and then the high-strength bolts can be removed, allowing the movable plate to flip towards the top plate and fall onto the top plate. At this time, the movable plate is at a horizontal angle. After flipping, it drives the support cylinder to be placed vertically. At this time, the cable reel can be vertically inserted into the support cylinder, which has the function of adapting to various working scenarios.

[0015] 2. In this utility model, through the arrangement of a bidirectional threaded rod, a movable groove, a slider, and a top rod, during use, after the cable reel is supported on the support cylinder, the bidirectional threaded rod is rotated by the throttle while the cable reel is held to prevent it from rotating. Utilizing the sliding effect of the slider in the movable groove, and its threaded connection with the bidirectional threaded rod, the rotation of the bidirectional threaded rod causes the two sets of sliders to move relative to each other, creating a flipping effect on the top rod. After flipping, the top rod causes the expansion plate to expand outward, supporting and fixing the inner wall of the cable reel. This allows for adaptation to different inner diameters of cable reels. After rotation, the limiting rod is inserted into the limiting hole to prevent the throttle from causing the bidirectional threaded rod to rotate back and causing the expansion plate to lose force. Utilizing the rotational effect of the support cylinder and the movable plate, the cable reel can rotate and unload cables normally. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-5As shown, a photovoltaic cable laying device includes a base plate 1 and a support cylinder 2. A groove 3 is provided in the middle of the upper surface of the base plate 1. A lead screw 4 is rotatably connected to the inner side wall of the groove 3. One end of the lead screw 4 passes through the inner side wall of the groove 3 and extends to the outer surface of the base plate 1. A vertical plate 5 is threadedly connected to the outer surface of the lead screw 4. A limit groove 6 is provided on one side of the upper surface of the base plate 1.

[0025] In this embodiment, the limiting groove 6 is slidably connected to the vertical plate 5, the inner sidewall of the vertical plate 5 is rotatably connected to the support rod 7, the outer surface of the support rod 7 is fixedly connected to the movable plate 8, a positioning hole 9 is opened on one side of the upper surface of the vertical plate 5, a high-strength bolt 10 is movably connected to the inner bottom wall of the movable plate 8, the high-strength bolt 10 is threadedly connected to the positioning hole 9, and a top plate 11 is fixedly connected to one side of the upper surface of the bottom plate 1.

[0026] In practical use, the rotation effect of the support rod 7 and the vertical plate 5 allows the movable plate 8 to flip. After rotating the movable plate 8 to a vertical angle, the two sets of high-strength bolts 10 are tightened into the positioning holes 9 to secure the movable plate 8. At this time, the cable reel can be placed horizontally on the support cylinder 2 for cable laying. If the cable reel needs to be placed vertically before fixing, the screw 4 can be rotated to move the vertical plate 5 to one side. The limiting groove 6 is concave, which can support the vertical plate 5 while limiting its position, preventing the screw 4 from being affected by gravity. Then, the high-strength bolts 10 are removed, allowing the movable plate 8 to flip towards the top plate 11 and fall onto the top plate 11. At this time, the movable plate 8 is at a horizontal angle. After flipping, it drives the support cylinder 2 to be placed vertically. The cable reel can then be vertically inserted into the support cylinder 2. This system has the function of adapting to various working scenarios. The height of the top plate 11 can be set according to actual needs, making it convenient for the movable plate 8 to be placed horizontally, allowing the bidirectional threaded rod 16 to be rotated from below.

[0027] In this embodiment, a handle 12 is fixedly connected to one end of the lead screw 4, a plug rod is inserted into one side of the handle 12, an insertion port is opened on one side of the top plate 11, a support leg 13 is fixedly connected to the lower surface of the bottom plate 1, and a self-locking wheel 14 is rotatably connected to the bottom end of the support leg 13.

[0028] In practical use, the screw 4 is rotated by the handle 12, and the plug is inserted into the socket after rotation, which makes it easy to limit the handle 12. At the same time, the self-locking wheel 14 has the effect of easy movement.

[0029] In this embodiment, the support cylinder 2 is rotatably connected to the movable plate 8, and a support disk 15 is rotatably connected to the outer surface of the movable plate 8 near the support cylinder 2.

[0030] In practical use, the rotation effect of the support cylinder 2 and the movable plate 8 allows the cable reel to rotate after being placed, which facilitates the cable laying operation. After the movable plate 8 is flipped to a horizontal angle, the rotating support plate 15 makes the cable reel rotate even more easily.

[0031] In this embodiment, one end of the support cylinder 2 passes through one side of the movable plate 8 and extends to the other side of the movable plate 8. A bidirectional threaded rod 16 is rotatably connected to one side of the support cylinder 2. A handle 17 is fixedly connected to one end of the bidirectional threaded rod 16. A limit rod is inserted into one side of the handle 17.

[0032] In practical use, turning the throttle 17 can drive the bidirectional threaded rod 16 to rotate, which has a transmission effect. After rotation, the throttle 17 can be easily fixed by the limit rod.

[0033] In this embodiment, a limiting hole 18 is provided on the outer surface of the support cylinder 2 near the throttle 17, and the size of the limiting hole 18 is adapted to the size of the limiting rod.

[0034] In actual use, after rotation, insert the limit rod into the limit hole 18 to prevent the handle 17 from causing the bidirectional threaded rod 16 to rotate and causing the expansion plate 22 to lose force.

[0035] In this embodiment, the support cylinder 2 has a hollow structure inside, and the outer surface of the support cylinder 2 is provided with a movable groove 19. A slider 20 is slidably connected inside the movable groove 19. There are two sliders 20, and they are threadedly connected to the bidirectional threaded rod 16.

[0036] In practical use, the sliding effect of the slider 20 in the movable groove 19 and the threaded connection with the bidirectional threaded rod 16 are utilized. After the support cylinder 2 is fixed, the rotation of the bidirectional threaded rod 16 can drive the two sets of sliders 20 to move relative to each other.

[0037] In this embodiment, a push rod 21 is rotatably connected to the outer surface of the slider 20, and an expansion plate 22 is rotatably connected to one end of the push rod 21.

[0038] In practical use, the rotation of the bidirectional threaded rod 16 drives the two sets of sliders 20 to move relative to each other, which produces a flipping effect on the push rod 21. After flipping, the push rod 21 drives the expansion plate 22 to expand outward.

[0039] Working principle: During use, the rotation of the support rod 7 and the vertical plate 5 allows the movable plate 8 to flip. After rotating the movable plate 8 to a vertical angle, two sets of high-strength bolts 10 are tightened into the positioning holes 9 to secure the movable plate 8. At this time, the cable reel can be placed horizontally on the support cylinder 2. The bidirectional threaded rod 16 is rotated by the handle 17, while the cable reel is held to prevent it from rotating. The sliding effect of the slider 20 in the movable groove 19, and its threaded connection with the bidirectional threaded rod 16, causes the bidirectional threaded rod 16 to rotate, driving the two sets of sliders 20 to move relative to each other. The top rod 21 is flipped, and after flipping, the top rod 21 drives the expansion plate 22 to expand outward, supporting and fixing the inner wall of the cable reel. It has the function of adapting to different inner diameters of cable reels. When the cable reel needs to be placed vertically before fixing, the screw rod 4 can be rotated to move the vertical plate 5 to one side, and then the high-strength bolt 10 can be removed, so that the movable plate 8 can be flipped towards the top plate 11 and fall onto the top plate 11. At this time, the movable plate 8 is at a horizontal angle. After flipping, it drives the support cylinder 2 to be placed vertically. At this time, the cable reel can be inserted vertically into the support cylinder 2. It has the function of adapting to various working scenarios.
