[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides an implementation scheme: in the modern electrical inspection process, primitive methods such as observation, smell and touch cannot immediately discover inconspicuous problems when encountering them, which easily leads to inspection errors. Therefore, in the electrical inspection process, a tool that can quantitatively detect the operating status of the circuit is needed.

[0020] In view of the above problems, the present application discloses an electrical maintenance inspection tool, which is specifically divided into a handheld hand tool 1 and a telescopic rod 2 as the main supporting part of the inspection tool. The handheld hand tool 1 is provided with a telescopic rod 2 with multiple telescopic stages, and the head end of the telescopic rod 2 is used to install a detection structure. The telescopic rod 2 can be used as an extension of the detection device to extend the detection structure to a place that the operator cannot reach. The fixed fixture 3 provided at the connection between the telescopic rod 2 and the handheld hand tool 1 is used to carry an operation panel 4, and the operation panel 4 is used to display the detection result of the detection structure;

[0021] Furthermore, the detection structure is based on the principle of electromagnetic induction. During the operation of the cable line, a magnetic field will be generated around the cable. Therefore, a detection device with weak magnetism is used to advance along the cable line to detect the magnetic field running around the cable line of the equipment. When the operating current is normal, the magnetic field generated will have a slight adsorption effect on the weak magnetic detection equipment, and the reading can be realized through the conversion of pulling force. When a short circuit or short circuit occurs, the current in the cable must be abnormal, so the detection data must be abnormal. This can avoid internal problems that cannot be discovered by human eyes or hands, and realize data quantification.

[0022] Specifically, the detection structure comprises: a rotating seat 5, a guide roller 6 and an assembly tube seat 7; wherein the rotating seat 5 is movably connected to the telescopic rod 2, and the assembly tube seat 7 is assembled on the rotating seat 5, and the rotating seat 5 can adjust the horizontal direction of the assembly tube seat 7. Further, the guide roller 6 arranged on the rotating seat 5 is used to clamp the two sides of the cable to achieve the guiding and spacing functions. Furthermore, the assembly tube seat 7 is a vacuum environment, and a sliding block 8 is arranged in the assembly tube seat 7. The sliding block 8 is a piston of a cylindrical structure. The sliding block 8 can slide axially in the assembly tube seat 7 to play a guiding and positioning role. An induction magnet 9 is arranged on one side of the sliding block 8. When the induction magnet 9 is close to the magnetic field environment of the cable, the magnetic field has an adsorption effect on the induction magnet 9, so that the weakly magnetic induction magnet 9 drives the sliding block 8 to slide, thereby driving the tension spring 10 to stretch, so that the tension spring 10 pulls the micro tension sensor 11, and the micro tension sensor 11 is electrically connected to the operation panel 4 to read the reading. In order to ensure the accuracy of the detection result, the assembly tube seat 7 should be parallel to the ground when used.

[0023] Furthermore, the rotating seat 5 is a plate of a rectangular structure, and a movable groove is opened at one end of the rotating seat 5. The assembly tube seat 7 is partially exposed in the movable groove. The specific length of the assembly tube seat 7 in the movable groove can be adjusted. The exposed length of the assembly tube seat 7 is changed according to the operating current of the cable. A rotating knob 12 with a limiting function is arranged on the outside of the assembly tube seat 7. A threaded hole is arranged on the rotating seat 5. By rotating the knob 12, the threaded structure at one end of the assembly tube seat 7 can be driven to engage with the threaded hole on the movable groove, thereby realizing position adjustment.

[0024] Furthermore, the guide rollers 6 are a pair of cylindrical rollers arranged on both sides of the assembly tube seat 7, and are movably connected to the two side walls of the movable groove of the rotating seat 5 through a pair of pins. During the forward movement of the rotating seat 5, the guide rollers 6 are arranged on both sides of the cable to align the assembly tube seat 7 with the cable.

[0025] Furthermore, an insulating rubber layer 13 is provided on the outside of the handheld hand tool 1, which plays an insulating protection role and also serves as a gripping cover.

[0026] To sum up, it can be seen that the electrical maintenance inspection tool relies on the magnetic field generated by the current when the cable is running as the detection variable, and uses the weak magnetic vacuum piston structure and the tension sensor to form a small conversion structure. The reading of the tension sensor is changed according to the strength of the magnetic field generated by the running current. Quantified data is obtained through conversion, which can avoid internal problems that cannot be discovered by human eyes or hands, and realize data quantification.
