[0002] A distribution network refers to a system that transmits electricity from a power plant to end users. It usually consists of transmission lines, substations, and distribution lines. During the power transmission process, high-voltage transmission lines transmit electrical energy from the power plant to substations in various regions, then the voltage is reduced through transformers, and the electrical energy is further transmitted to the final users via distribution lines.

[0003] When a fault occurs in the distribution network, it needs to be detected to locate and analyze the fault, and prepare for subsequent maintenance.

[0004] Currently, when detecting a fault, the fault detector is set to appropriate modes and parameters, the detection connector of the fault detector is connected to the cable or equipment in the distribution network, then the fault detector is started, and the distribution network is detected, and the output data and signals are analyzed. According to the detection results, the possible fault types and locations are determined.

[0005] However, when connecting the fault detector to the cable or equipment, only the detection wire harness is simply pulled. After use, the staff still needs to manually wind it up, and it cannot be automatically wound up, resulting in a long winding-up time and wasting manpower.

[0006] Therefore, it is necessary to provide a distribution network fault detection device to solve the above problems.

Detailed implementation manners

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] As Figure 1 shown, the present application provides a distribution network fault detection device, including a box body 1, and a detection component 2 is arranged inside the box body 1, and the detection component 2 is used for detecting faults;

[0026] As Figure 1 shown, the detection component 2 includes a detector 21 arranged inside the box body 1, and the detector 21 is used for detecting cables or equipment in the distribution network. At the same time, multiple groups of storage bags 22 are arranged on the box body 1 to facilitate the storage of tools during detection, such as insulating gloves, etc.;

[0027] At the same time, a contraction component 3 is arranged inside the box body 1, and the contraction component 3 is used for winding and unwinding wire bundles;

[0028] As Figures 2 - 4 shown, the contraction component 3 includes multiple groups of mounting frames 31 fixedly installed on the box body 1. At the same time, a reel box 32 is fixedly installed on the mounting frame 31. At the same time, a fixed rod 35 is fixedly installed inside the reel box 32, and a circular cavity (not marked in the figure) is opened on the reel box 32, and the fixed rod 35 is located inside the circular cavity;

[0029] And a reel 33 is rotatably mounted on the fixed rod 35. One side of the reel 33 is fixedly mounted with a ratchet wheel 34. At the same time, the ratchet wheel 34 is rotatably mounted at one end of the fixed rod 35. At the same time, the ratchet wheel 34 is located inside the circular cavity. At the same time, a winding spring 36 is sleeved on the fixed rod 35. One end of the winding spring 36 is fixedly connected to the fixed rod 35, and the other end of the winding spring 36 is fixedly connected to the ratchet wheel 34. And the winding spring 36 is located inside the ratchet wheel 34;

[0030] It should be noted that a wire harness is wound around the reel 33. One end of the wire harness is connected to the detector 21, and the other end of the wire harness is connected with a detection joint (not shown in the figure). And two groups of opening grooves (not shown in the figure) for the wire harness to pass through are formed on the winding box 32. When detection is needed, the detection joint is pulled to drive the winding wheel 33 to rotate on the fixed rod 35 and synchronously drive the ratchet wheel 34 to rotate. At this time, the ratchet wheel 34 continuously tightens the winding spring 36 during the rotation process to wind it up. After the detection is completed, the detection joint is loosened. At this time, the winding spring 36 resets, synchronously driving the ratchet wheel 34 to reset, thereby driving the reel 33 to reset to drive the wire harness to wind around the reel 33;

[0031] At the same time, a limiting component 4 is arranged inside the box body 1, and the limiting component 4 is used for the limiting operation of the contraction component 3;

[0032] As Figures 3 - 4 shown, the limiting component 4 includes a rotating rod 44 rotatably mounted on the winding box 32. A clamping block 41 is fixedly mounted on the rotating rod 44. The clamping block 41 is located inside the circular cavity. It should be noted that ratchet teeth are arranged at both ends of the clamping block 41. Among them, the ratchet teeth meshed with the ratchet wheel 34 are the first ratchet teeth, and the other group of ratchet teeth are the second ratchet teeth. At the same time, two concave surfaces are arranged on one side of the clamping block 41. Among them, the concave surface close to the first ratchet teeth is the first concave surface, and the other group of concave surfaces is the second concave surface. The first concave surface corresponds to the second ratchet teeth, and the second concave surface corresponds to the first ratchet teeth. And a convex surface is arranged between the two concave surfaces;

[0033] At the same time, a dial block 45 is fixedly mounted on the rotating rod 44. By turning the dial block 45, the angle of the rotating rod 44 can be changed. And a chute (not marked in the figure) is formed inside the winding box 32. A ball 43 is slidably arranged inside the chute. And a spring 42 is jointly arranged on the inner wall of the chute and the ball 43. And the ball 43 is located in the second concave surface of the clamping block 41;

[0034] In the initial state, the first ratchet teeth of the clamping block 41 are meshed with the ratchet wheel 34. At this time, the ball 43 is located in the second concave surface. When the ratchet wheel 34 rotates in the reverse direction, since the first ratchet teeth are meshed with it and the first ratchet teeth are matched with the end face of the clamping block 41 when it rotates in the reverse direction through the end face of the clamping block 41 to resist the ratchet wheel 34, so that it cannot rotate in the reverse direction to achieve one-way rotation;

[0035] During the inspection, the inspection connector is pulled, and the ratchet 34 is driven to rotate through the reel 33. The ratchet 34 continuously hits the first ratchet tooth, thereby driving the clamping block 41 to continuously rotate in one direction. At this time, the clamping block 41 continuously hits the ball 43, so that it moves in the slide groove and the second concave surface, and is continuously reset by the action of the spring 42, so that the ratchet 34 rotates, thereby facilitating the extension of the wire harness. After being pulled to the specified position, the ratchet 34 and the first ratchet tooth of the clamping block 41 are meshed to limit the ratchet 34.

[0036] When winding is required, the shift block 45 is shifted, and the shift block 45 drives the second ratchet tooth of the clamping block 41 to mesh with the ratchet wheel 34, and at the same time, the ball 43 is squeezed into the slide groove through the convex surface of the clamping block 41, and when the clamping block 41 rotates to the first concave surface, the ball 43 is ejected into the first concave surface due to the spring 42, and at this time, the ratchet wheel 34 can only rotate in the reverse direction, so that the wire harness is wound on the reel 33 under the drive of the winding spring 36;

[0037] At the same time, a tensioning assembly 5 is provided on the contraction assembly 3, and the tensioning assembly 5 is used to provide a certain tension when the wire harness is rolled up;

[0038] like Figure 3 As shown, the tensioning assembly 5 includes a connecting block 51 fixedly mounted on the rotating rod 44, and a roller 52 is rotatably mounted on one end of the connecting block 51 away from the rotating rod 44, and a rotating drum 53 is rotatably mounted inside the winding box 32. It should be noted that in the initial state, the wire harness is located above the roller 52;

[0039] When pulling out the wire harness, since the roller 52 is located below the wire harness, the wire harness can be pulled smoothly. When the wire harness is reeled in after the inspection, due to the shifting of the shifting block 45, the connecting block 51 synchronously drives the roller 52 to rotate. At this time, the roller 52 is located above the rotating drum 53. At this time, the cooperation between the roller 52 and the rotating drum 53 makes the wire harness have a certain tension, so as to ensure that the wire harness is reeled in and the wire harness is more neat and tight.

[0040] To sum up, during detection, the wire harness of appropriate length is pulled out through the contraction component 3, and then the detection head on the wire harness is connected to the object to be detected. At this time, the limit component 4 limits it to prevent the wire harness from automatically returning to its position. After the detection is completed, the dial block 45 is adjusted to adjust the position of the tensioning component 5. At this time, the wire harness is reset under the drive of the winding spring 36, and the tensioning component 5 makes it more neatly wound.

[0041] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
