Description

Technical Field

[0001] The utility model belongs to the field of power grid fault detection, and in particular relates to a power grid fault detection and positioning device. Background Art

[0002] The power cable fault tester is a special cable testing equipment used to solve the test of open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults of power cables, as well as the accurate test of open circuit and short circuit faults of coaxial communication cables and local telephone cables.

[0003] The patent application with announcement number CN220671567U discloses a low-voltage distribution network fault detection and positioning device, including: a flatbed truck, a cable fault detector, a detection probe, a wireless remote control, a current alarm mechanism, a clamping mechanism and an automatic moving mechanism. The cable fault detector is installed on the flatbed truck, and a detection probe is installed on one side of the flatbed truck. The detection probe is electrically connected to the cable fault detector through an electric wire. A clamping mechanism for clamping the detection probe is installed on the side of the flatbed truck. A storage tank is provided on the flatbed truck, and a wireless remote control is placed in the storage tank. The flatbed truck is equipped with an automatic moving mechanism and a current alarm mechanism.

[0004] However, the above-mentioned prior art has the following disadvantages when used:

[0005] Paragraph 0025 of the aforementioned document describes that "When using the low-voltage distribution network fault detection and locating device, first turn on the cable fault detector, then take out the wireless remote control, stand at a distance from the flatbed truck, and then control the automatic moving mechanism to drive the flatbed truck to move, so that the detection probe moves to the buried cable." Combined with the attached manual, Figure 1 It can be seen that the detection probe needs to be positioned on one side of the flatbed truck through a clamping ring so that the detection probe can be moved to the upper side of the buried cable, and the buried cable can be detected and processed through the detection probe. When the inner wall of the clamping ring fixes the outer wall of the detection probe, the outer wall of the detection probe will be damaged.

[0006] Therefore, a power grid fault detection and positioning device is proposed to solve the above-mentioned drawbacks. Utility Model Content

Both sides of the flatbed vehicle 1 are equipped with fixed cylinders 116. The interior of the fixed cylinders 116 is slidably fitted with detection probes 117.

[0027] The threaded rod 119 is rotatably engaged with the upper side of the flatbed truck 1, and the thread directions on both sides of the threaded rod 119 are opposite. Both sides of the threaded rod 119 are threadedly engaged with sliding blocks 120, and there are two rotating plates 123 rotatably engaged between the upper end of the sliding block 120 and the upper end of the detection probe 117.

[0028] The upper side of the flatbed trolley 1 of this embodiment is provided with a storage slot 103, a guide slot 118 located on one side of the storage slot 103, and a groove 107 located on one side of the guide slot 118. A wireless remote control 104 is placed inside the storage slot 103. A first motor is installed inside the guide slot 118. One end of a threaded rod 119 is installed on the output end of the first motor. A sliding block 120 is slidably fitted inside the guide slot 118. A threaded hole 121 is provided on one side of the sliding block 120. The threaded hole 121 is threadedly fitted with the threaded rod 119. Four support plates 105 are installed at the bottom of the flatbed trolley 1. A first through hole 106 is provided on one side of the support plate 105. Two adjacent first through holes 106 are provided. 06 is rotatably matched with a rotating shaft 111, and rollers 113 are installed at both ends of the rotating shaft 111. The outer wall of the roller 113 is evenly equipped with a plurality of rubber ridges 114. A driven wheel 112 is installed on the circumference of one of the rotating shafts 111, and a fixed block 108 is installed on the upper side of the flatbed trolley 1. A second motor is installed on one side of the fixed block 108, and a rotating rod 109 is installed at the output end of the second motor. A driving wheel 110 is installed at one end of the rotating rod 109, and a transmission belt 115 is matched with the driving wheel 110 and the driven wheel 112. The transmission belt 115 is located inside the groove 107, which facilitates the rotation of the transmission belt 115 inside the flatbed trolley 1 through the groove 107.

[0029] The upper side of the flatbed truck 1 of this embodiment is equipped with a fault detector 101 and a mobile power supply 102 located on one side of the fault detector 101. A wire 127 is installed between the fault detector 101 and the detection probe 117. First fixing rods 122 are installed on both sides of the sliding block 120. A second through hole 125 is opened at the first end of the rotating plate 123. The first fixing rod 122 is located inside the second through hole 125. Two second fixing rods 124 are installed at the upper end of the detection probe 117. A third through hole 126 is opened at the second end of the rotating plate 123. The second fixing rod 124 is located inside the third through hole 126, which facilitates the second end of the rotating plate 123 to rotate around the second fixing rod 124 through the third through hole 126.

[0030] Working principle:

[0031] When using the power grid fault detection and positioning device, first turn on the fault detector 101, then the staff takes out the wireless remote control 104, and the staff stands at a distance away from the flatbed car 1 to drive the roller 113, and the flatbed car 1 is driven to move by the roller 113, and then the threaded rod 119 is rotated, and the threaded rod 119 drives the two sliding blocks 120 to slide. Because the threads on both sides of the threaded rod 119 are in opposite directions, the two sliding blocks 120 slide close to each other, and the sliding block 120 drives the detection probe 117 to slide downward inside the fixed tube 116 through the rotating plate 123, so that the detection probe 117 moves to the top of the underground buried cable, and then, the flatbed car 1 is moved along the direction of the cable, and the fault point of the cable is detected by the detection probe 117. When the fault point is detected, the cable fault detector 101 sends an alarm signal to remind the staff nearby, and then the staff marks and records the fault point here.

[0032] The detection probe 117 is set so that the detection probe 117 can be moved above the underground buried cable under the action of the rotating plate 123. On the one hand, the underground buried cable is detected by the fault detector 101 to detect whether the underground buried cable has a fault problem. On the other hand, it reduces the problem of damage to the outer wall of the detection probe 117 caused by the inner wall of the clamping ring when fixing the detection probe 117 in the prior art, making the detection process of the detection probe 117 more convenient.
