Description

Technical Field

[0001] The invention relates to the technical field of power maintenance, and in particular to a multifunctional low-voltage area patrol and maintenance tool. Background Art

[0002] The low-voltage substation is an indispensable part of the distribution network. As the end of power transmission, it consists of a large number of power equipment and lines. Due to the complex structure and large current of the low-voltage substation, various faults are prone to occur, and regular inspections and maintenance are required in the low-voltage substation. General inspections are basically carried out through manual on-site inspections, but due to the complex geographical conditions of the low-voltage substation, it is very inconvenient for staff to carry out inspections.

[0003] The inspection of low-voltage areas also includes the inspection of low-voltage meters and the recording of electricity consumption data. Some household meters are set at a higher position. When inspecting the household meters, it is necessary to carry ladders, electrical testing equipment and other maintenance tools. The large number of tools carried not only increases the difficulty of the inspection work, but also poses a greater safety hazard. In order to ensure the personal safety of the staff and improve the efficiency of the inspection, special inspection tools are used to assist the inspection. In addition to the basic electrical testing function, the inspection tools also have functions such as lighting and remote shooting, which greatly improves the inspection efficiency. In order to improve the applicability of the inspection tools, the inspection tools are designed as a multi-segment combination structure. However, during use, the threaded connection method often encounters the following situations: due to inadequate maintenance of the inspection tools, after long-term use, the metal threads at the connection are oxidized and rusted. When connecting between the segments, it is very difficult to twist them into place, and they need to be twisted repeatedly, which takes a lot of time and affects work efficiency; in the case of threaded connection, the speed of disassembly and assembly is too fast, and the centripetal force generated by the rotation of the tool becomes larger.

The groove 201j-5 cooperates to make the sliding groove block 201j-4 and the limiting slider 201j-1 move, releasing the limit of the fixed slider 201i-1 by the limiting slider 201j-1, making the fixed slider 201i-1 rebound through the second return spring 201i-2, releasing the clamping and fixing state of the internal clamping part 201, and adjusting one end of the connecting rod 203c to be fixedly connected with the hinged bottom ring 203a, and adjusting the other end of the connecting rod 203c to be fixedly connected with the resistance block 203b.

[0047] Specifically, the hinged bottom ring 203a includes a hinged pressure ring 203a-1, a swing plate 203a-2, a pressure slider 203a-3 and an adjustment lever 203a-4. The hinged pressure ring 203a-1 is hingedly connected to the operating top rod 101, and the hinged pressure ring 203a-1 is in contact with the sliding outer ring 202a. The swing plate 203a-2 is fixedly connected to the inner side of the hinged pressure ring 203a-1, and the swing plate 203a-2 cooperates with the rotating rod 202c-4. When the hinged pressure ring 203a-1 rotates, the hinged inner ring 202c is driven to rotate through the cooperation of the swing plate 203a-2 and the rotating rod 202c-4. The pressure slider 203a-3 is fixedly connected to one end of the hinged pressure ring 203a-1 close to the sliding outer ring 202a. The sliding outer ring 202a is fixedly connected, and a pressing groove 202a-1 matching the pressing slider 203a-3 is provided on one side of the sliding outer ring 202a close to the pressing slider 203a-3. When the hinged bottom ring 203a drives the hinged inner ring 202c to rotate, the hinged bottom ring 203a drives the sliding outer ring 202a to slide through the cooperation of the pressing slider 203a-3 and the pressing groove 202a-1. The sliding of the sliding outer ring 202a drives the hinged inner ring 202c and the card contact 202c-3 to slide, thereby releasing the card contact 202c-3 from the snap block 301a. The adjusting lever 203a-4 is fixedly connected to the outer side of the hinged pressing ring 203a-1, and the adjusting lever 203a-4 is used to drive the hinged pressing ring 203a-1 to rotate.

[0048] Operation process: by turning the adjusting lever 203a-4, the hinged bottom ring 203a is driven to rotate, the hinged bottom ring 203a rotates and drives the abutment block 203b to rotate through the adjusting connecting rod 203c, the abutment block 203b rotates and drives the sliding slot block 201j-4 to slide through the abutment slide slot 201j-5, thereby releasing the limiting effect of the limiting slider 201j-1 on the fixed slider 201i-1, releasing the clamping and fixing state of the inner clamping member 201, and releasing the inner clamping member 201 through the rotation of the hinged bottom ring 203a. When the clamping member 201 is in the clamping fixed state, the hinged bottom ring 203a rotates through the swing plate 203a-2 and the pressure slider 203a-3 to drive the hinged inner ring 202c and the sliding outer ring 202a to rotate while sliding along the direction of the installation groove 101b, thereby releasing the clamping fixed state of the clamping contact 202c-3 and the buckle block 301a, and releasing the clamping fixed state of the external clamping member 202, thereby solving the problem that the existing patrol and maintenance tools use threaded connections during assembly, which are difficult to disassemble and affect work efficiency.

[0049] Example 4

[0050] Reference Figure 1-9, this embodiment is different from the above embodiments in that: in order to meet the needs of inspection, some auxiliary inspection tools can be added to the rod body. A visual probe is installed on the top of the insulating component 100, and a light compensation device is also installed on the visual probe, so that the probe can clearly capture the electrical equipment even in a dim light environment, thereby improving the applicable scope of the probe. A metal probe is also provided on the top of the insulating component 100, which can assist the staff to open the meter box cover set at a high place, press the counting button of the meter through the probe, complete the recording of the data in the meter box, avoid the staff from working at high altitude, and improve the safety performance.

[0051] Specifically, a visual probe assembly is added to the top of the operating rod 101, which can increase the operator's observation range through the probe, making it easier to detect electrical equipment at heights and collect data. At the same time, a light compensation device is added next to the visual probe assembly, which enables the probe to collect data on electrical equipment normally when the surrounding environment is dim due to insufficient light, greatly improving the applicability of the inspection tool.

[0052] Furthermore, a metal probe equipped with an electrical testing function is provided on the same side of the visual probe assembly. The metal probe can detect leakage of electrical equipment at high places, and the metal probe can be used to remotely open the covers of meter boxes and other electrical equipment, avoiding the risk of electric shock for workers and greatly improving the safety of inspection work.

[0053] At the same time, the metal probe can also be used as a tool to drive away small animals, preventing them from crawling into the meter box or other electrical equipment and causing damage to the equipment.

[0054] Preferably, a mobile bracket is provided at the bottom of the segmented connecting rod 102 to fix the mobile terminal device. The mobile terminal device can display the images taken by the visual probe, which is convenient for staff to operate and collect data.
