Description

Technical Field

[0001] This utility model relates to the field of underwater construction line laying technology, and in particular to a wire laying device for water conservancy construction. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their goals. In order to remotely control the electrified equipment such as water pumps and sluice gates in water conservancy projects, it is necessary to use wires to connect to the control equipment. The laying of wires is a part of water conservancy construction.

[0003] To reduce economic costs, traditional wire laying is generally done manually. However, during manual laying, the wire is subject to stress during winding, which can cause knots. At the same time, as the wire is manually tensioned, the insulation at the knots is prone to stress damage, reducing its insulation performance. Based on this, a wire laying device for hydraulic construction is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a power cable laying device for water conservancy construction, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a power cable laying device for water conservancy construction, including a transport platform. Four limiting seats are fixedly connected to the center of the top surface of the transport platform. Each of the four limiting seats is rotatably connected to a support column. Each of the four support columns is fixedly connected to the center of four support rods. Each of the four support columns is provided with a limiting mechanism. An installation frame is provided at one corner of the top surface of the transport platform, which extends downward at an angle. Three support plates are fixedly connected to one side of the installation frame. Each of the three support plates is provided with five guide wheels on its top surface.

[0006] Preferably, one side of the top surface of the transport platform is hollowed out, and a holding plate is provided on the side of the transport platform near the hollowed-out area. All four sides of the holding plate are bent upwards. The hollowed-out area in this solution can reduce the weight of the transport platform, while the holding plate provides a place for the wire coils, so that the transport platform can carry a certain number of wire coils and move around, making it convenient to replace the wire coils in time and complete the unwinding of the wires.

[0007] Preferably, in any of the above schemes, the bottom surface of the transport platform near the limiting seat is threaded with four lead screws. One end of each of the four lead screws is fixedly connected to a handwheel, and the other end of each of the four lead screws is threaded with a concave block. The four concave blocks fit into the bottom ends of the four support columns. This scheme facilitates the formation of a feeding mechanism. Rotating the handwheel makes it easy to rotate the lead screws, which in turn drives the four concave blocks to move, and it is easy to adjust the friction between the blocks and the four support columns.

[0008] Preferably, the bottom of each of the above-mentioned schemes is stepped, which facilitates its cooperation with the limiting seat. At the same time, the bottom of the support column can penetrate the limiting seat and cooperate with the four concave blocks.

[0009] Preferably, in any of the above embodiments, each of the four limiting mechanisms includes a locking nut, a retaining ring, two connecting rods, and a vertical plate. The locking nut is threadedly connected to the top of the support column, the retaining ring is located below the locking nut and slidably connected to the support column, one end of each of the two connecting rods is rotatably connected to the top and bottom of one side of the vertical plate, and the other end of each of the two connecting rods is rotatably connected to the middle of the support column and the outer wall of the retaining ring, respectively. This embodiment facilitates pushing the retaining ring by rotating the four locking nuts, thereby pushing the vertical plates away from each other, supporting the interior of the wire roll, and preventing relative sliding between the wire roll and the limiting mechanism.

[0010] Preferably, all three support plates are placed at different angles, and the distance between the three support plates is the same. This arrangement allows the three support plates to have different angles, which in turn allows the guide wheels to have different installation angles. The five guide wheels are grouped together, which facilitates the guidance of the wires. At the same time, the rotation of the guide wheels facilitates the laying of the wires.

[0011] This utility model has the following advantages: 1. This power cable laying device for water conservancy construction uses four support columns and four limiting mechanisms. Each of the four support columns has a support rod fixedly connected to its center, thus providing support for the wire reel. Simultaneously, rotating the locking nut pushes the retaining rings down, causing the vertical plates to move away from each other, thereby supporting the inside of the wire reel. By setting up an installation frame, three support plates are fixedly connected to its side, allowing the wire to be threaded sequentially between adjacent guide wheels. This pushes the transport platform to lay the wire inside the trench during water conservancy construction, preventing knotting. The overall structure is simple and easy to promote and use.

[0012] 2. This power cable laying device for water conservancy construction, by setting up a holding plate, facilitates the placement of wire rolls and allows for the temporary storage of a certain amount of wire rolls. By setting up four lead screws, four handwheels, and four concave blocks, rotating the handwheels causes the four lead screws to rotate relative to the transport platform, thereby pushing the concave blocks to move. Adjusting the friction between the concave blocks and the support columns facilitates the adjustment of the tension during power cable laying. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0016] like Figures 1 to 5 As shown, a power cable laying device for water conservancy construction includes a transport platform 1. Four limiting seats 8 are fixedly connected to the middle of the top surface of the transport platform 1. Support columns 2 are rotatably connected inside each of the four limiting seats 8. Four support rods 12 are fixedly connected to the middle of each of the four support columns 2. Limiting mechanisms 3 are provided in the middle of each of the four support columns 2. An installation frame 5 is provided at one corner of the top surface of the transport platform 1, which extends downward at an incline. Three support plates 6 are fixedly connected to one side of the installation frame 5. Five guide wheels 7 are provided on the top surface of each of the three support plates 6.

[0017] One side of the top surface of the transport platform 1 is hollowed out, and a holding plate 4 is provided on the side of the transport platform 1 near the hollowed-out area. All four sides of the holding plate 4 are bent upwards. As an optional technical solution of this utility model, the hollowed-out area can reduce the weight of the transport platform 1. At the same time, the holding plate 4 provides a place for the wire rolls, so that the transport platform 1 can move with a certain number of wire rolls, which is convenient for timely replacement of the wire rolls and completion of wire unwinding.

[0018] Four lead screws 9 are threadedly connected to the bottom surface of the transport platform 1 near the limit seat 8. A handwheel 11 is fixedly connected to one end of each of the four lead screws 9, and a concave block 10 is threadedly connected to the other end of each of the four lead screws 9. The four concave blocks 10 fit against the bottom ends of the four support columns 2. As an optional technical solution of this utility model, this facilitates the formation of a feeding mechanism. Rotating the handwheel 11 makes it easy to rotate the lead screws 9, which pushes the four concave blocks 10 to move, and facilitates the adjustment of the friction between them and the four support columns 2.

[0019] The bottom of each of the four support columns 2 is stepped, which is an optional technical solution of this utility model. This makes it easier to cooperate with the limiting seat 8. At the same time, the bottom of the support column 2 can penetrate the limiting seat 8 and cooperate with the four concave blocks 10.

[0020] Each of the four limiting mechanisms 3 includes a locking nut 301, a retaining ring 302, two connecting rods 303, and a vertical plate 304. The locking nut 301 is threadedly connected to the top of the support column 2. The retaining ring 302 is located below the locking nut 301 and is slidably connected to the support column 2. One end of each of the two connecting rods 303 is rotatably connected to the top and bottom of one side of the vertical plate 304. The other ends of each of the two connecting rods 303 are rotatably connected to the middle of the support column 2 and the outer wall of the retaining ring 302, respectively. As an optional technical solution of this utility model, this facilitates pushing the retaining ring 302 by rotating the four locking nuts 301, thereby pushing the vertical plate 304 away from each other and supporting the inside of the wire roll, preventing relative sliding between the wire roll and the limiting mechanism 3.

[0021] The three support plates 6 are all placed at different angles, and the distance between the three support plates 6 is the same. As an optional technical solution of this utility model, this makes it easy for the three support plates 6 to present different angles, thereby allowing the guide wheels 7 to present different installation angles. The five guide wheels 7 are grouped together, which facilitates the guidance of the wires. At the same time, the rotation of the guide wheels 7 facilitates the laying of the wires.

[0022] The following steps are required when using this power cable laying device for water conservancy construction: 1) When using, place the wire coil in the middle of the four support columns 2; 2) Rotate the locking nut 301 to push the retaining ring 302 down to lower the height, so that the limiting mechanism 3 can stably support the wire coil; 3) Pass the wires sequentially between the five adjacent guide wheels 7; 4) Rotate the handwheel 11 to push the concave block 10 to move, adjusting the friction between it and the bottom of the four support columns 2; 5) Move the transport platform 1 along the bank of the water conservancy channel to facilitate the deployment of the power lines.

[0023] In summary, during use, the user utilizes four support columns 2 and four limiting mechanisms 3, with four support rods 12 fixedly connected to the middle of each of the four support columns 2, thus providing support for the wire reel. Simultaneously, rotating the locking nut 301 lowers the retaining rings 302, causing the vertical plates 304 to move away from each other, thereby supporting the interior of the wire reel. The mounting frame 5, with three support plates 6 fixedly connected to its sides, allows the wire to be threaded sequentially between adjacent guide wheels 7, propelling the transport platform 1 to lay the wire on the water conservancy platform. The trench is designed to prevent knotting during construction. The overall structure is simple and easy to promote and use. A holding plate 4 is provided to facilitate the placement of wire rolls and to temporarily store a certain amount of wire rolls. Four lead screws 9, four handwheels 11, and four concave blocks 10 are provided. By rotating the handwheels 11, the four lead screws 9 rotate relative to the transport platform 1, which in turn drives the concave blocks 10 to move. The friction between the concave blocks 10 and the support column 2 is adjusted to adjust the tension of the wire during deployment.
