Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a special bracket for cable fault step-by-step detection suitable for cement floors. Background Technology

[0002] In power systems, cable fault detection typically uses the step-through method. Traditional step-through testing supports are usually probe structures, which can only be used in muddy ground and cannot function properly on increasingly common concrete surfaces, greatly limiting their application in urban environments. Furthermore, installing traditional supports in muddy ground requires digging and securing them, a cumbersome process. On hard surfaces, this increases installation difficulty and affects detection accuracy. Additionally, contact with damp soil makes the metal components of the support susceptible to corrosion, and friction with hard objects like stones can cause wear on the base and support components, affecting their lifespan and structural stability. Utility Model Content

[0003] To overcome the problems in the prior art, this application proposes a special bracket for cable fault step-by-step detection on cement floors, which solves the problems of limited application scenarios, inconvenient operation, and poor durability of existing cable fault step-by-step detection brackets.

[0004] A special support for cable fault step-by-step detection on cement floors includes support legs, sponge, insulating tension tube, and direction tester. Each support leg consists of two parts, and each support leg includes an insulating lifting tube and a copper base located at the lower end of the insulating lifting tube. The sponge is detachably connected to the bottom of each copper base. The insulating tension tube is horizontally arranged to connect the two support legs. The direction tester is electrically connected to the two copper bases.

[0005] Furthermore, the top of the two support legs is provided with a bracket handle, and a handle rubber sleeve is installed on the bracket handle.

[0006] Furthermore, the height or width of the bracket is adjusted by a locking cap connecting the insulating tension tube and the insulating lifting tube.

[0007] Furthermore, the sponge is connected to the copper base by bolts.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting conductive sponge at the bottom of the copper base, the probe structure of the traditional bracket is replaced, so that the bracket can complete signal acquisition without being inserted into the ground. This breaks through the limitation of traditional brackets that can only be used on muddy ground, and can be effectively applied to urban hardened roads such as cement and asphalt, greatly expanding the application scenarios.

[0009] 2. This utility model eliminates the cumbersome installation process of digging holes and fixing. Simply wet the sponge and place it on the ground for testing. This significantly improves the convenience of operation and work efficiency. The adjustable insulating tension tube and lifting tube can adapt to different testing environments and operator habits, further enhancing convenience.

[0010] 3. The use of insulated tubing as the main support structure avoids the risk of electric shock to operators; the copper base combined with sponge design reduces direct friction between the equipment and the ground, preventing premature wear of components, enhancing the durability and structural stability of the equipment, and ensuring long-term stable operation.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] See Figure 1-4 A special support for cable fault stepping method detection suitable for cement floors, mainly composed of two support legs, an insulating tension tube 102 and a direction tester 103; Each support leg consists of a vertical insulated lifting tube 105 and a copper base 106 fixed to its bottom. Both the insulated lifting tube 105 and the insulated tension tube 102 are made of insulating material to ensure the safety of the operator during use and to avoid electric shock accidents. The top of the support leg is equipped with a support handle 101 for easy hand holding. The support handle 101 can be covered with a handle rubber sleeve to increase the comfort and friction of the grip, making it easy for the testing personnel to carry and accurately operate the support. The two support legs are connected by at least one horizontal insulating tension tube 102. A locking cap 104 is provided at the connection between the insulating tension tube 102 and the insulating lifting tube 105. By loosening or tightening the locking cap 104, the extension length of the insulating tension tube 102 and the lifting height of the insulating lifting tube 105 can be adjusted, thereby adjusting the overall width and height of the support to adapt to different testing environments and operational requirements. See Figure 2 The key components of this invention are the copper base 106 and the sponge 107. Each copper base 106 has a sponge 107 detachably connected to its bottom via bolts or other means. During testing, the sponge 107 is wetted with water, utilizing its conductivity to ensure good electrical contact with the cement floor. Simultaneously, the sponge 107's softness provides cushioning and anti-slip properties, reducing friction and vibration between the support and the ground, and enhancing placement stability. See Figure 2-4 The direction tester 103 is electrically connected to two copper bases 106 via connecting cables. Its built-in signal receiving and processing module receives step voltage signals collected from the ground via the copper bases 106 and wet sponge 107. When the high-voltage generator conducts high voltage to the faulty cable, the potential difference signal from the ground is transmitted to the direction tester 103 through this bracket. Based on the characteristics of the received feedback signal, the direction tester 103 indicates the approximate direction of the cable fault point to the operator through pointer deflection, thereby helping to quickly locate the fault and improve the accuracy and efficiency of detection.

[0016] Work process: Check and confirm that all components are properly connected. Connect the direction tester 103 to the two copper bases 106 using the connecting cable. Install the sponge 107 on the bottom of the copper bases 106 and wet it thoroughly with water. Hold the bracket handle 101 and move the device to the cement ground above the cable path to be tested. Adjust the width and height of the bracket to a suitable range using the locking cap (104) according to the site conditions and ease of operation. Apply a high-voltage pulse signal to the faulty cable using the high-voltage generator. Move the bracket along the cable path while observing the pointer movement of the direction tester 103. When the pointer deviates significantly, it indicates that the testing bracket is crossing the fault point, thus determining the approximate location of the fault point. After use, turn off the high-voltage generator and perform a safe discharge operation on the copper bases 106. After confirming safety, store the device.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
