Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical testing equipment, and in particular to an electrical equipment fault detection device. Background Technology
[0002] In the fields of power and communications, the normal operation of cables is crucial. Once a cable fault occurs, the key to ensuring the stable operation of the system is to quickly and accurately locate and repair the fault. Existing cable fault testers consist of a transmitter, a locator, and a positioning bracket. The transmitter and the locator transmit data to each other via wireless signals, while the locator and the positioning bracket transmit data signals via wires.
[0003] When using the positioning bracket, if the ground is dry or cement, the probe of the positioning bracket cannot make good contact with the ground to form a current loop because the conductivity of the ground is usually poor. This will affect the detection of the cable fault location. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This utility model provides, for example Figure 1-6 The electrical equipment fault detection device shown includes a positioning bracket 1, a probe 3 for fault point measurement and positioning is provided at the bottom end of the positioning bracket 1, and a connecting rod 4 for connecting the positioning bracket 1 and the probe 3 is provided at the top end of the probe 3. It also includes:
[0035] Water storage component 5 is located outside the connecting rod 4. Water storage component 5 is used to provide water source. Water storage component 5 includes water storage cylinder 51. Water outlet pipe 52 for water outlet is provided at the bottom end of water storage cylinder 51. An extrusion component for squeezing water source is provided inside water storage cylinder 51.
[0036] Mounting component 6 is installed on the outer wall of the water storage cylinder 51 and is used for mounting the water storage cylinder 51 and the connecting rod 4.
[0037] Locking component 7 is located at the connection between mounting component 6 and water storage tank 51, and is used to fix the position of water storage tank 51.
[0038] The output end of the positioning bracket 1 is electrically connected to a positioning instrument 2 for receiving signals from the positioning bracket 1, and the bottom end of the connecting rod 4 is fixedly connected to the top end of the probe 3.
[0039] Furthermore, the positioning bracket 1 and the positioning instrument 2 are electrically connected via a cable, and the connecting rod 4 is hinged to the positioning bracket 1. The positioning bracket 1, the positioning instrument 2, the connecting rod 4, and the probe 3 are components of the existing LD-2001 cable fault detector. The probe 3 detects specific signals emitted by the device by contacting the ground or the cable sheath, which helps to determine the precise location of the fault point. When the cable is short-circuited to ground or has a leakage fault, the device will apply a high-voltage pulse to the cable, and a voltage gradient will be formed on the ground around the fault point. The probe 3 quickly locates the fault point by measuring the potential difference between two points on the ground.
[0040] The bottom end of the water storage cylinder 51 is connected to the top end of the water outlet pipe 52, and the extrusion component slides through the inside of the water storage cylinder 51.
[0041] Extrusions include:
[0042] Rubber stopper 53 is slidably inserted inside water storage cylinder 51;
[0043] Linkage rod 54, the bottom end of which is fixedly connected to the top end of rubber plug 53;
[0044] Push plate 55, the bottom end of push plate 55 is fixedly connected to the top end of linkage rod 54.
[0045] Furthermore, the rubber stopper 53 is a piston made of rubber, sealing the inner wall of the water storage cylinder 51. The rubber stopper 53 is bonded and fixed to the linkage rod 54, and the push plate 55 is bonded and fixed to the linkage rod 54. The water outlet pipe 52 is a thin tube with a diameter corresponding to a fine needle tip. Therefore, the water stored inside the water storage cylinder 51 will form droplets at the end of the water outlet pipe 52 due to surface tension, thus slowing down the flow of water out of the water outlet pipe 52. This is the working principle of the water storage component 5. Similar to the principle of a medical syringe, the water storage cylinder 51 is tilted and placed through the placement tube 61, with the water outlet pipe 52 facing the bottom of the probe 3. When encountering dry road surfaces or cement ground, the push plate 55 is pressed, causing the push plate 55 to drive the linkage rod 54, which in turn drives the rubber stopper 53 to pressurize the water source inside the water storage cylinder 51. The water is then sprayed out from the water outlet pipe 52 and directed towards the probe 3, increasing the conductivity between the probe 3 and the ground. The number of water storage components 5 corresponds to the number of probes 3.
[0046] Installation component 6 includes:
[0047] Placement tube 61 is sleeved on the outer wall of water storage tube 51 and is used to place water storage tube 51.
[0048] Clamp 63 is fitted onto the outer wall of connecting rod 4 and is used to clamp connecting rod 4.
[0049] A connector is provided between the placement cylinder 61 and the clamp 63.
[0050] The connector includes a bent rod 62, with both ends of the bent rod 62 fixedly connected to the opposite side of the placement cylinder 61 and the clamp 63, respectively. A fixing bolt 64 for locking the clamp 63 is provided on one side of the clamp 63.
[0051] The bottom end of the placement cylinder 61 has a round hole for inserting the water outlet pipe 52.
[0052] Furthermore, the number of installation components 6 corresponds to the number of water storage components 5. The clamp 63 is an existing device. The clamp 63 is fitted onto the outer wall of the connecting rod 4, and with the cooperation of the fixing bolts 64 and nuts, the clamp 63 is firmly clamped to the outer wall of the connecting rod 4. This is existing technology. The outer wall of the clamp 63, away from the fixing bolts 64, is welded to the bending rod 62. The clamp 63 is in a horizontal state. The bending rod 62 changes the placement angle of the placement cylinder 61, allowing the water storage cylinder 51 placed inside the placement cylinder 61 to... The inclined probe 3, the bending rod 62 and the placement tube 61 are welded and fixed at the contact part. The inner diameter of the placement tube 61 corresponds to the outer diameter of the water storage tube 51. The size of the round hole at the bottom of the placement tube 61 is 1.5 times the size of the water outlet pipe 52. So that before each use of the positioning bracket 1, the water outlet pipe 52 can be inserted into the water storage tank, the push plate 55 can be pulled to move away from the water outlet pipe 52, so that the water storage tube 51 is filled with water, and then the water storage tube 51 is placed into the placement tube 61, and the water outlet pipe 52 is inserted and connected to the round hole.
[0053] The locking assembly 7 includes a limiting ring 73 fitted in the middle of the water storage cylinder 51. A pressing block 72 for pressing the limiting ring 73 is provided at the top of the limiting ring 73. An insertion hole 71 is provided at the bottom of the pressing block 72. The water storage cylinder 51 is inserted into the inside of the insertion hole 71. A fixing block 78 is fixedly connected to the back of the placement cylinder 61. A cavity 77 is provided in the middle of the fixing block 78. A protruding rod 74 is fixedly connected to the bottom end of the pressing block 72. A rotating column 75 is fixedly connected to the bottom end of the protruding rod 74. A torsion spring 76 is provided at the bottom of the rotating column 75. The rotating column 75 and the torsion spring 76 are both inserted into the inside of the cavity 77. The protruding rod 74 is inserted into the inner wall at the top of the cavity 77.
[0054] Furthermore, the through hole 71 is adapted to the water storage cylinder 51, allowing the pressing block 72 to be fitted onto the middle of the water storage cylinder 51 when it rotates. The limiting ring 73 is fixedly fitted onto the middle of the water storage cylinder 51. When it is necessary to fix the position of the water storage cylinder 51, the position of the water storage cylinder 51 is fixed by fixing the position of the limiting ring 73. During use, the limiting ring 73 cannot move due to the obstruction of the placement cylinder 61 and the pressing block 72, thus fixing the position of the limiting ring 73 and fixing the position of the water storage cylinder 51 by fixing the position of the limiting ring 73. A hole adapted to the through rod 74 is opened on the inner wall of the top of the cavity 77, and neither the rotating column 75 nor the pressing block 72 can pass through this hole. The through rod 74 is used to connect the rotating column 75 located inside the cavity 77 and the pressing block 72 located outside the cavity 77. This design restricts the positions of the rotating column 75, the through rod 74, and the pressing block 72, so that the pressing block 72 rotates around the through rod 74. When the torsion spring 76 is not deformed, the pressing block 72 is sleeved in the middle of the water storage cylinder 51. When the pressing block 72 rotates, it drives the through rod 74 and the rotating column 75 to rotate. The torsion spring 76 is deformed by the pull of the rotating column 75. When the rotation of the pressing block 72 is lost, the torsion spring 76 returns to its original deformation and drives the rotating column 75, the through rod 74, and the pressing block 72 to reset. This design prevents the pressing block 72 from moving randomly during use.
[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
