Description

Technical Field

[0001] The present invention belongs to the field of cable joints, and more specifically, relates to a cable joint protection box with good heat dissipation effect. Background Art

[0002] The cable joint at the middle part of the cable line is called the intermediate joint. The main function of the cable intermediate joint protection box is to prevent the leakage of substances generated by the explosion of the cable intermediate joint. Since the intermediate joint connects two cables together, the resistance at the intermediate joint increases. Therefore, during operation, a large amount of heat will be generated inside the intermediate joint. If the heat cannot be discharged in time, the cable will be damaged. The existing cable intermediate joint protection box dissipates heat by opening heat dissipation holes. Since there is no device such as a fan that generates air flow inside the cable intermediate joint protection box, the heat dissipation effect of the heat dissipation holes is not significant, and the humid air in the air will enter along the heat dissipation holes, reducing the moisture-proof effect.

[0003] The patent application with the publication number CN217984492U discloses a cable intermediate joint protection box with good heat dissipation effect. Paragraph 0024 of its specification discloses: a main body device and a heat dissipation device. The heat dissipation device is placed on the top of the main body device. The main body device protects the intermediate joint, and the heat dissipation device discharges heat to improve safety. The main body device includes an upper protection box, a lower protection box, and a mounting plate. The mounting plates are welded on both sides of the upper protection box and the lower protection box. Mounting holes are opened on the mounting plates, and bolts are screwed at the mounting holes. The upper protection box and the lower protection box are fixed by bolts to form a protection box. The protection box is in a cylindrical structure. The inner diameter of the end of the protection box is reduced, and a limiting groove is opened at the end of the protection box. A limiting ring is clamped in the limiting groove. A limiting block is arranged inside the limiting ring. Multiple groups of limiting blocks are arranged at equal angles along the inner wall of the limiting ring. The limiting blocks in the limiting ring prevent the cable from falling off from the limiting ring. The limiting ring is blocked by the limiting groove, so that the cable will not fall off from the protection box, improving the installation stability. The heat dissipation device includes a skeleton, vertical heat dissipation fins, horizontal heat dissipation fins, and heat exchange fins. The skeleton is inserted into the top of the upper protection box. The skeleton is in a Y-shaped structure. A lower fixing plate is welded at the bottom of the skeleton. The lower fixing plate is located inside the upper protection box. A heat exchange fin is arranged at the bottom of the lower fixing plate. The heat exchange fin is arranged vertically downward, and heat exchange grooves are opened on both side walls of the heat exchange fin. Multiple groups of the heat exchange fins are arranged at equal intervals. The heat exchange fin transfers the heat in the air inside the protection box to the skeleton. The heat exchange grooves increase the contact area between the air and the heat exchange fin, thereby increasing the heat exchange efficiency.

[0004] However, in actual use, it is necessary to fix the upper protective box and the lower protective box through bolts, and protect the cable joint through the upper protective box and the lower protective box. Since the number of bolts is multiple, it is necessary to screw each bolt one by one to clamp the upper protective box and the lower protective box, and this process will affect the efficiency of protecting the cable joint. Since there is no cleaning structure on one side of the heat dissipation device, it is easy to cause the problem that dust adheres to one side of the heat dissipation device. If the dust adhering to one side of the heat dissipation device is not cleaned in time, it will affect the heat dissipation effect of the heat dissipation device on the cable intermediate joint.

[0005] For this reason, a cable intermediate joint protective box with good heat dissipation effect is proposed to solve the above drawbacks. Summary of the Invention

The arc-shaped column 123 drives the sliding plate 118 to slide. The sliding plate 118 slides on the periphery of the rubber pad 116 through the through hole 119. The sliding plate 118 drives the spring 122 to slide through the annular plate 121. The arc-shaped column 123 drives the L-shaped rod 125 to slide through the arc-shaped rod 124. One end of the L-shaped rod 125 drives the brush to slide on one side of the heat dissipation port 127 through the arc-shaped scraping plate 126, and cleans the dust attached to one side of the heat dissipation port 127, reducing the problem of dust attachment on one side of the heat dissipation port 127.

[0046] The provided guide groove 108 enables one end of the sliding block 110 to slide inside the guide groove 108 under the action of the threaded rod 114, and guides the sliding direction of the sliding block 110 through the guide groove 108, reducing the problem of the sliding block 110 tilting during sliding and improving the stability of the sliding block 110 during sliding.

[0047] The provided annular groove 120 enables one end of the annular plate 121 to rotate inside the sliding plate 118 through the annular groove 120, and guides the rotation direction of the annular plate 121 through the annular groove 120, reducing the problem of the annular plate 121 tilting during rotation and the problem of the annular plate 121 rotating out of the inside of the annular groove 120, and improving the stability of the annular plate 121 during rotation.
