Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a submarine cable fault locating device which is easy to install. Background Art

[0002] Submarine cables (especially high-voltage cables) are an important part of offshore wind farms, islands and cross-sea power transmission. The safe operation of submarine cables is crucial to the stability of offshore wind power systems and cross-sea power transmission. Once a submarine cable fails, it may cause power outages, causing huge economic losses and social impacts. In addition, submarine optical cables are important infrastructure for international and domestic communications, carrying a large amount of data transmission tasks. Failure of optical cables will cause communication interruptions, affecting the transmission of information and the availability of the Internet.

[0003] Existing cable fault detection and positioning methods usually use computer technology and microelectronics technology, and have the characteristics of high intelligence, complete functions, wide application range, accurate testing, and easy use. Commonly used cable fault locators generally include a box and an instrument body located in the box.

[0004] The existing cable fault locator also has the following disadvantages during use: during use, the locator needs to be connected to the cable core through a connecting wire. Since one end of the cable is located on the ground, in order to ensure stability during the detection process, it also needs to be supported and fixed by a bracket, which increases the complexity of the connection and the bracket is not easy to take. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that in order to ensure stability during the detection process, it is necessary to support and fix it through a bracket, which increases the complexity of the connection and the bracket is not easy to take, and to propose a submarine cable fault locating device that is easy to install.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A submarine cable fault locating device that is easy to install, comprising a box and a fault locator, wherein the fault locator is arranged in the box, a box cover for protecting the fault locator is hingedly connected to one side of the box, and a plurality of supporting legs for supporting the box are arranged at the bottom of the box, which are folded at the bottom of the box when not in use;

[0008] A support rod is provided in the box cover, and the support rod can be stored in the box cover when not in use. A lower clamp ring is provided on the top of the support rod, and an upper clamp ring is adjustable on the top of the lower clamp ring. The lower clamp ring cooperates with the upper clamp ring to clamp the cable. A clamp ring corresponding to the wire core is also provided on the top of the support rod to fix the wire core.

[0009] A fixing piece is provided at the bottom of the box body for simultaneously fixing a plurality of stored supporting legs.

[0010] In a possible design, a second fixing seat is fixed on the top wall of the box cover, a waist-shaped hole is opened on one side of the second fixing seat, a sliding column is arranged in the waist-shaped hole, the support rod is fixedly sleeved on the sliding column, and a limiting member for limiting the support rod is arranged on the second fixing seat.

[0011] In one possible design, the limiting member includes a positioning column fixed at the bottom of the support rod, and the top of the second fixing seat is provided with a positioning hole used in conjunction with the positioning column. When the positioning column is inserted into the positioning hole, the support rod will not rotate on the second fixing seat.

[0012] In a possible design, a first fixed seat corresponding to the support leg is fixed at the bottom of the box, the support leg is rotatably mounted on the first fixed seat, and a plurality of insertion rods are fixed at one end of the support leg away from the first fixed seat. After the insertion rods are inserted into the ground, the support leg will not move.

[0013] In a possible design, the fixing member includes a magnetic strip fixed to the bottom of the box, and the supporting legs are made of metal used in conjunction with the magnetic strip.

[0014] In a possible design, a support bar is rotatably provided on the top of the support rod, and a plurality of the clamping rings are fixedly provided on the top of the support bar for accommodating the clamping rings.

[0016] In the present application, when in use, first open the four support legs, then insert the insertion rod into the ground to support the box body, then open the box cover, pull and pull the support rod upward, drive the sliding column to move in the waist-shaped hole, make the support rod perpendicular to the second fixing seat, then press the support rod downward, so that the positioning column at the bottom of the support rod is inserted into the positioning hole, and the support rod will not shake at this time;

[0017] Secondly, place one end of the detection cable between the lower clamp ring and the upper clamp ring, and then rotate the nut ring to move the nut ring downward on the screw rod. The downward movement of the nut ring can drive the upper clamp ring to approach the lower clamp ring to clamp the cable. After the clamping is completed, rotate the support bar to make the support bar perpendicular to the support rod, and clamp multiple wire cores in the clamp ring in turn. At this time, the cable is fixed;

[0018] Finally, connect the wire core to the fault locator through a connecting wire, and start the fault locator to detect and locate.
