Technical Field

[0001] The utility model relates to the technical field of spiral protective sleeves, in particular to a spiral protective sleeve for a high-voltage cable. Background Art

[0002] High-voltage cable is a type of power cable, which refers to the power cable used to transmit power between 1kv-1000kv, and is mostly used in power transmission and distribution. During the use of high-voltage cables, spiral protective sheaths are needed to protect high-voltage cables. Spiral protective sheaths are elastic tubular sheaths that are often used to protect wires, cables, pipes, etc., and can effectively prevent them from being damaged by wear, tear, folding, etc. At the same time, the spiral protective sheath has certain properties such as waterproof, acid and alkali resistance, temperature resistance, pressure resistance, and wear resistance, which makes it widely used in the industrial field.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the two ends of the spiral protective sleeve in the prior art are usually fixed to the high-voltage cable by gluing or screws. When the high-voltage cable needs to be maintained and repaired, the spiral protective sleeve is difficult to remove from the high-voltage cable, thereby reducing the efficiency of maintenance and repair of the high-voltage cable. Utility Model Content

[0006] By adopting the above technical solution, when the spiral protective cover body needs to be installed, the staff will wrap the spiral protective cover body around the high-voltage cable, then pull the limit block to pull the fixing belt out of the fixing box and wrap it around the high-voltage cable, insert the limit block into the limit groove and limit the limit block by the limit assembly, and the fixing belt remains tightened under the action of the winding spring, so that the spiral protective cover body is installed on the high-voltage cable by tightening the high-voltage cable with the fixing belt, which is convenient for installing or removing the spiral protective cover body, thereby improving the efficiency of maintenance and repair of the high-voltage cable.

[0007] Furthermore, a fixing groove is formed on the side wall of the limit block, and the limit assembly includes a limit rod that is penetrated and slidably connected to the side wall of the fixed box and a pulling block fixed to the end of the limit rod, and the limit rod is plugged into the fixing groove.

[0008] By adopting the above technical solution, when the limit block needs to be limited, the staff inserts the limit block into the limit groove, and inserts the limit rod into the fixing groove by pulling the block, thereby fixing the limit block in the limit groove.

[0009] Furthermore, a spring groove is provided on the side wall of the fixed box, a clamping spring is arranged in the spring groove, one end of the clamping spring is fixed to the inner wall of the spring groove, and the other end of the clamping spring is fixed to the side wall of the pulling block.

[0010] By adopting the above technical solution, the pulling block keeps the limit rod in the plugged state with the fixing groove under the elastic force of the pressing spring, thereby reducing the probability of the limit block falling off due to the limit rod detaching from the fixing groove.

[0011] Furthermore, a yielding portion cooperating with the limiting block is provided at the bottom of the limiting rod.

[0012] By adopting the above technical solution, the limit block squeezes the limit rod into the fixed box through the yielding part during the process of inserting into the limit groove, and then the limit rod is automatically plugged into and matched with the fixed groove under the elastic force of the clamping spring, eliminating the tedious operation of manually pulling the limit rod when fixing the limit block, and facilitating the rapid fixation of the limit block.

[0013] Furthermore, the surface area of ​​the limit block is larger than the opening area of ​​the sliding hole.

[0014] By adopting the above technical solution, the situation where the fixing belt completely enters the fixing box is avoided, which makes it convenient for the staff to pull the fixing belt through the limit block.

[0015] Furthermore, the inner wall of the spiral protective sleeve body is provided with a plurality of convex strips.

[0016] By adopting the above technical solution, the multiple convex strips increase the friction between the inner wall of the spiral protective sleeve body and the surface of the high-voltage cable, and reduce the probability of displacement of the spiral protective sleeve body on the surface of the high-voltage cable.

[0017] Furthermore, a fluorescent strip is provided on the outer wall of the spiral protective sleeve body.

[0018] By adopting the above technical solution, the fluorescent strip makes the spiral protective cover body more eye-catching, serves as a warning to the staff, and reduces the probability of the staff accidentally touching the high-voltage cable.
