Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, specifically relating to a waterproof sealing structure for cables used in water conservancy projects. Background Technology

[0002] The waterproof sealing structure for cables used in water conservancy projects is mainly designed to ensure that cables maintain good electrical performance and physical integrity in aquatic or humid environments, preventing short circuits, corrosion, or other electrical faults caused by moisture intrusion. For water conservancy projects, cables often need to withstand harsh working conditions, including long-term exposure to water or high humidity environments. Using a suitable waterproof sealing structure can significantly extend the service life of cables and their connections, and reduce maintenance costs. By using specially designed sealing components (such as polyurethane sheaths, rubber sealing rings, etc.), moisture can be effectively prevented from entering the cable from the external environment, thereby avoiding electrical faults caused by water immersion.

[0003] In the existing technology, for some heavy machinery or occasions that require particularly stable connections, the cable ends are usually fixed with bolts. However, this is inconvenient when disassembling, maintaining or replacing the cable. In addition, bolts may rust in rainy or humid environments. Once the bolts rust, not only will their fastening effect be reduced, but the difficulty of subsequent disassembly will also be significantly increased. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0023] Reference Figures 1-3 This is an embodiment of the present invention, which provides a waterproof sealing structure for cables used in water conservancy projects, comprising:

[0024] Main distribution box 100 is used to supply power to the equipment that needs to be connected;

[0025] The quick-release mechanism 200 includes an internally threaded block 201 fixedly installed on the outer surface of the main distribution box 100, an elastic clamping block 202 fixedly installed on the inner surface of the internally threaded block 201, an anti-slip pad 203 fixedly connected to the inner surface of the elastic clamping block 202, a rotating component 204 threadedly connected to the internally threaded block 201 and used in conjunction with the elastic clamping block 202, and a cable 205 that clamps the elastic clamping block 202 when the rotating component 204 rotates.

[0026] Specifically, the main distribution box 100 and the cable 205 are connected, and the anti-slip pad 203 is attached to the outer surface of the cable 205.

[0027] Furthermore, the rotating assembly 204 includes a hollow bolt 204a threadedly connected to the internal threaded block 201, a pressing block 204b fixedly mounted on the outer surface of the hollow bolt 204a and used in conjunction with the elastic clamping block 202, and a knob 204c fixedly mounted on the outer surface of the other end of the hollow bolt 204a.

[0028] Furthermore, the inner surface of the compression block 204b slides in contact with the outer surface of the elastic clamping block 202, and the inner surface of the knob 204c fits against the outer surface of the cable 205.

[0029] The rotating knob 204c causes the compression block 204b to gradually compress the elastic clamping block 202, thereby achieving a stable clamping of the cable 205 by the elastic clamping block 202, which facilitates operation and improves the convenience and stability of use.

[0030] Preferably, the inner surface of the knob 204c and the outer surface of the cable 205 are made of polyvinyl chloride, and the outer end face of the cable 205 is connected to the inside of the main distribution box 100.

[0031] It should be noted that the outer surface of cable 205 is sheathed with polyurethane material, and a rubber sealing ring is provided at the other end of the cable 205 connection.

[0032] The outer surface of cable 205 is covered with a polyurethane sheath, which improves the wear resistance, flexibility and waterproof performance of cable 205. The polyurethane material can not only resist external physical wear, but also maintain the integrity and functionality of cable 205 under bending and stretching conditions, thereby ensuring its long-term durability in various application environments. At the same time, a rubber sealing ring is set at the connection of the other end of cable 205 to further enhance the sealing effect of the connection, effectively preventing the intrusion of moisture and other impurities.

[0033] In use, the main distribution box 100 serves as the core component for power distribution, providing power to all equipment via cable 205. When fixing cable 205, rotating knob 204c causes hollow bolt 204a to rotate at the thread of internal thread block 201. As knob 204c rotates, pressure is applied to elastic clamp block 202 by pressure block, which clamps and fixes cable 205. Protective pads effectively prevent cable 205 from falling off. When maintenance and disassembly of cable 205 are required, rotating knob 204c causes hollow bolt 204a to rotate at the thread of internal thread block 201. As knob 204c rotates, pressure is released from elastic clamp block 202 by pressure block, elastic clamp block 202 returns to its initial state, and the clamping of cable 205 is released.

[0034] In summary, through the cooperation of the various components of the quick-release mechanism 200, not only is the stability of the cable 205 ensured when it needs to be fixed, but the disassembly process of the cable 205 during inspection and maintenance is also simplified, improving convenience and overall reliability.
