Description

Technical Field

[0001] The utility model relates to the technical field of circuit detection, in particular to a power distribution line detection device used for power distribution engineering construction. Background Art

[0002] Power supply and distribution engineering refers to the design, installation, commissioning, and maintenance of power supply and distribution systems for buildings, factories, and equipment. Distribution lines are the lines that carry electricity from step-down substations to distribution transformers, or from distribution substations to power users. The construction of power supply and distribution projects often requires laying a large number of distribution lines. To ensure the proper functioning of these lines, distribution line testing devices are required.

[0003] After searching, the patent application number CN202122411714.X discloses a fault detection device for use in the renovation and construction of distribution line engineering in the field of circuit detection technology, including a device housing, the inner bottom wall of the device housing is fixedly connected to the device body, the inner wall of the device housing is fixedly connected to a bearing, the inner ring surface of the bearing is fixedly connected to a rotating shaft, the front of the bearing is fixedly connected to a spring box, and a winding spring is provided inside the spring box. In the utility model, by arranging a bearing, the spring box can be fixedly connected to the inner wall of the device housing, and the rotating shaft can be rotatably connected to the inner wall of the device housing. By arranging a winding spring, the rotating shaft can be driven to rotate when resetting. By arranging a winding mechanism, the excessively long wire can be wound up, so that the fault detection device for the renovation and construction of distribution line engineering solves the problem that the wire length cannot be adjusted and the mutual entanglement causes inconvenience to the detection work of the staff.

[0004] However, this patent still has some shortcomings. During the actual use of this type of distribution line, when the staff pulls out the detection head and the wire, the winding spring will continue to exert a winding force on the wire. The staff needs to overcome the force of the winding spring for a long time, which can easily cause fatigue. If the hands accidentally slip, the detection head and the wire will retract into the device casing, affecting the use of the distribution line detection work.

[0005] Therefore, we propose a power distribution line detection device for power distribution engineering construction. Utility Model Content

The ends of the two winding springs 9 away from the winding shaft 13 are fixedly installed on the inner wall of the spring seat 8. A limiting ring 10 is fixedly sleeved on the rear part of the two winding shafts 13. The limiting ring 10 is located on the two winding shafts 13. The rear part of the ring 10 is fixedly sleeved with a gear ring 14, and the two winding shafts 13 are fixedly installed with wires 12. The two wires 12 extend out of the outside of the device housing 1 at one end away from the winding shaft 13 and are fixedly installed with a detection head 11. The front end of the device housing 1 is located between the two spring seats 8 and is fixedly installed with an extrusion rod 21. The rear end of the extrusion rod 21 is fixedly installed with a slide 19, and the outer sliding sleeve of the slide 19 is provided with a sleeve 18. The rear end of the slide 19 is fixedly installed with a return spring 20, and the rear end of the return spring 20 is fixedly installed on the inner wall of the sleeve 18. The rear end of the sleeve 18 is fixedly installed with a pressure plate 15, and clamps 17 are fixedly installed on both sides of the pressure plate 15. The two clamps 17 are engaged with the corresponding gear rings 14 on the side away from each other.

[0023] The rear end of the pressure plate 15 is fixedly installed with a touch pressure rod 16, and the rear end of the touch pressure rod 16 extends out of the device housing 1, so that the pressure plate 15 and the card 17 are pushed forward by the touch pressure rod 16. The slide 19 is set to a hexagonal shape, and the corresponding slide 19 is set in the sleeve 18. This design can prevent the sleeve 18 from rotating. The front end of the device housing 1 is fixedly installed with a display screen 3. The front end of the device housing 1 is located below the display screen 3 and is fixedly installed with an operation panel. The operation panel and the display screen 3 are convenient for users to debug and test. The front end of the device housing 1 is provided with a protective cover 2, and the rear end of the protective cover 2 is fixedly installed with two card strips 6. The front end of the device housing 1 is located on both sides of the display screen 3 and is provided with card slots 4.

At this time, the winding shaft 13 loses its limit, and the wire 12 can be pulled by the two detection heads 11 to rotate the winding shaft 13 to extend the wire 12 to the appropriate length. Then, the touch pressure rod 16 is released. At this time, the reset spring 20 drives the sleeve 18, the pressure plate 15 and When the clamp 17 returns to its original position, the two clamps 17 are respectively engaged and connected to the corresponding gear ring 14, so that the winding shaft 13 can be limited and fixed. After use, the touch pressure rod 16 is pressed forward. At this time, the winding shaft 13 loses its limit again, and the two winding springs 9 are reset to drive the winding shaft 13 to rotate, so that the wire 12 can be wound into the device housing 1. This distribution line detection device for power distribution engineering construction is easy to use. Through the above-mentioned components, the winding shaft 13 and the winding spring 9 can be limited and fixed during use, so as to avoid the problem that the detection head 11 retracts when the user's hand slips, affecting the normal detection work. At the same time, the protective cover 2 can be used to block and protect the display screen 3 when it is not needed, thereby further improving the protection capability of the device.
