Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and in particular relates to a protective device for ship power cables. Background Technology

[0002] During shipbuilding, numerous auxiliary equipment are used, such as large fans, lock boxes, dehumidifiers, and load boxes. With the increasing size of ships, the number of auxiliary equipment required during construction has increased, leading to a greater number of temporary cables being installed on board. These temporary cables are in direct contact with the edges of the hull's outer plating. Since ships are constantly swaying in berths, over time, the contact points with the cables are prone to wear and leakage, potentially causing serious accidents and injuries. Therefore, this application designs a protective device for ship power cables, which is temporarily installed on the edge of the ship's outer plating during construction to protect the cables and also saves time and effort when pulling and releasing temporary cables. Summary of the Invention

[0003] The technical problem this invention aims to solve is the lack of effective protection between the edge of the ship's outer plating and temporary cables, which makes personnel extremely susceptible to electric shock and danger. Therefore, it provides a ship power cable protection device that is simple to manufacture, easy to operate, has good protective effect, high safety performance, and low cost.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A protective device for marine power cables includes a base plate and a pair of upright frames arranged in parallel. The base plate is horizontally installed on the bottom surface of one side of the upright frames. A fixed shaft is installed between the pair of upright frames located above the base plate. A rubber washer is fitted on the fixed shaft, and the rubber washer can rotate freely on the fixed shaft.

[0006] It also includes a locking plate, which is vertically fixedly installed below the base plate, and the locking plate is provided with several locking holes.

[0007] Furthermore, it also includes a locking screw that passes through the locking hole. A locking nut is installed on the locking screw, and the locking screw is restricted to rotating only vertically toward the locking plate side. The protective device is fixed to the side of the ship by the locking screw that passes through the locking plate and the locking nut.

[0008] Furthermore, the locking nuts are symmetrically arranged on the side wall of the locking plate, and the paired locking nuts are located on the side of the locking plate away from the upright frame.

[0009] Furthermore, the height of the pair of upright frames is higher than that of the fixed shaft, so that when the cable is pulled on the rubber sleeve gasket on the fixed shaft, it is confined to the inside of the upright frames.

[0010] Furthermore, there are gaps between the rubber sleeve washer and the fixed shaft and the upright frame, allowing the rubber sleeve washer to rotate freely.

[0011] Furthermore, the protective plate is fixedly connected to the base plate and the locking plate, and the protective plate, the base plate and the locking plate are all vertically assembled and assembled in the center position.

[0012] The advantages and positive effects of this utility model are:

[0013] This utility model is inexpensive, simple in structure, highly safe, and provides good protection and safety. It is also highly versatile: it can be used on all ships under construction, is small in size, lightweight, easy to move, and readily available. Attached Figure Description

[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that these drawings are designed for illustrative purposes only and are not intended to limit the scope of this utility model.

[0017] Figure 3 This is a top view of the marine power cable protection device provided in this embodiment of the utility model. Detailed Implementation

[0018] First, it should be noted that the specific structure, features, and advantages of this utility model will be described in detail below by way of examples. However, all descriptions are for illustrative purposes only and should not be construed as limiting the utility model in any way. Furthermore, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, can still be arbitrarily combined or deleted among these technical features (or their equivalents) to obtain more other embodiments of this utility model that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0020] like Figure 1 ,2 As shown in Figures 1 and 3, this embodiment provides a protective device for marine power cables, including a base plate 1 and a pair of upright frames 3, as follows: Figure 2 As shown, a pair of upright frames 3 are arranged in parallel, and the base plate 1 is horizontally installed on the bottom surface of one side of the upright frame 3; a fixed shaft 5 is installed between the pair of upright frames 3 located above the base plate 1, and a rubber sleeve washer 6 is fitted on the fixed shaft 5, and the rubber sleeve washer 6 can rotate freely on the fixed shaft 5.

[0021] It also includes a locking plate 2, which is vertically fixedly installed below the base plate 1, and the locking plate 2 is provided with a plurality of locking holes.

[0022] It also includes a locking nut 7 and a locking screw (not shown in the figure). The locking nut 7 is assembled with the locking plate 2. After assembly, the locking screw can rotate relative to the locking plate 2, and the locking screw is restricted to rotating only vertically towards the locking plate 2, so that the power cable protection device is firmly and reliably fixed to the side of the ship.

[0023] A plurality of locking nuts 7 are provided on the side wall of the locking plate 2, and locking screws are installed on the locking nuts 7. The protective device is fixed to the side of the ship by passing through the locking hole A and the locking screws of the locking nuts 7.

[0024] like Figure 2 As shown, the locking nuts 7 are arranged in pairs on the side wall of the locking plate 2, and the paired locking nuts 7 are located on the side of the locking plate 2 away from the upright frame 3.

[0025] The height of the pair of upright frames 3 is higher than that of the fixed shaft 5, so that when the cable is pulled on the rubber sleeve gasket 6 on the fixed shaft 5, it is restricted to the inside of the upright frame 3.

[0026] It also includes a rubber sleeve washer 6, which is mounted on the fixed shaft 5. There are gaps between the rubber sleeve washer 6 and the fixed shaft 5 and between the rubber sleeve washer 6 and the upright frame 3. The fit gap is 1mm, which allows the rubber sleeve washer 6 to rotate freely. The length of the rubber sleeve washer can accommodate multiple temporary cables.

[0027] The protective plate 4 is assembled with the base plate 1 and the locking plate 2. The protective plate 4 is assembled perpendicularly to the base plate 1 and the locking plate 2 and is assembled in the center position.

[0028] When in use, the power cable protection device is fixed by tightening the set screw. After tightening, the structure is stable, safe and reliable, and easy to operate, serving as a temporary protection for cables on board. It should be noted that the diameter of the locking hole on the locking plate is slightly larger than the diameter of the nut hole. The set screw is screwed into the locking nut and the locking hole of the locking plate to lock the power cable protection device. The protection device has high safety and good protection effect.

[0029] In this embodiment, the height of the fixed shaft is moderate, allowing the cable to fall completely within the frame for effective protection, while maintaining a certain gap between the cable and the base plate, making cable loading and unloading quick and easy. The rubber sleeve washer is mounted on the fixed shaft and is not removable. The rubber sleeve washer and the fixed shaft work together, allowing the rubber sleeve washer to rotate freely around the fixed shaft. Compared with existing protective devices, this power cable protection device has a simpler structure, is more user-friendly, provides better protection, and can be reused repeatedly, saving more time and effort.

[0030] When installing the protective device, first place the power cable protective device at the installation position, ensuring the inner side of the frame is tightly fitted against the outer side plate. Slowly insert the locking screw into the locking nut and slowly rotate the locking screw with a wrench until it passes through the locking plate and fits tightly against the outer side plate. Repeat the above operation for the remaining locking screws to ensure that the bolt torque at the locking screw is uniform. Check whether the power cable protective device is secure. Once the installation is complete, place the temporary cable on the rubber sleeve washer 6 between a pair of frames 3. Construction workers can then pull and release the temporary cable through the rubber sleeve washer.

[0031] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
