Description

Technical Field

[0001] The invention relates to the technical field of electric power, in particular to a quick-assembly and disassembly full-time electrician. Background Art

[0002] At present, the main process of general switching operations carried out by the substation operation and maintenance team in the substation is as follows (taking the example of stopping a single line and removing the standby as a safety measure): disconnect the switch - pull open the upper and lower switches on both sides of the switch - verify that there is no voltage on the three-phase side of the line on the lower switch - install a grounding short-circuit line on the line side of the lower switch.

[0003] After careful discovery, it was found that there are major security loopholes in the current tester for electricity testing and hanging the ground short-circuit line: the operator uses a contact tester to test the electricity phase by phase, replaces the tester after verifying that there is no voltage, and then hangs up the ground short-circuit line. If the line reverses power after verifying that there is no electricity and before hanging the ground wire, it cannot be discovered. If the ground short-circuit line is directly hung, it will cause a serious short-circuit electrical accident, burn power equipment, and even endanger the life of the operator. There are many inventions about testers, but they all have many defects. For example, application number: CN201811268575.6, a universal tester, can continuously test electricity, but there is an elastic element on the hook, which is not only difficult to hang, but also inconvenient to remove, and is not practical. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing electric tester has a serious safety loophole when testing electricity. After the electric tester verifies that there is no electricity in the three phases, the electric tester is replaced. However, if a line reverse point occurs, if the grounding line is directly hung, a serious accident will occur early. In order to solve the above problem, the present invention provides a quick-install and disassemble full-time electric tester.

[0005] The objective of the present invention is achieved in the following manner: the present invention provides a quick-assembly and disassembly full-time electroscope, comprising an upper clamp and a lower clamp, the upper clamp comprising a vertical rod a, the two ends of the vertical rod a are respectively fixed with a top plate clamp a and a bottom plate a; the lower clamp comprises a top plate clamp b and a bottom plate b, a vertical rod b is fixed between the top plate clamp b and the bottom plate b, the top plate clamp b and the bottom plate b of the lower clamp are both inserted into the vertical rod a, the vertical rod b passes through the bottom plate b and the bottom plate a, and the electroscope is fixed at the lower end of the vertical rod b, a translation device is provided between the bottom plate a and the bottom plate b, and the translation device drives the bottom plate a and the bottom plate b to move relative to or toward each other.

[0006] The described translation device comprises a rebounder device, which comprises a rebounder body and a rebounder bumper, and the rebounder body is provided with a clamping arm capable of clamping the bumper together, the rebounder body is fixed on the lower side of the base plate b, the rebounder bumper is fixed on the upper side of the base plate a, a stopper is horizontally fixed on the vertical rod a of the upper clamp, and a compression spring is provided between the stopper and the top plate clamp b.

[0007] An electroscope operating rod is fixed on the electroscope.

[0008] The translation device comprises an electric telescopic rod, one end of which is fixed on the bottom plate a, and the other end of which is fixed on the bottom plate b.

[0009] A semi-elliptical groove is provided on the lower side of the top plate clamp a and the upper side of the top plate clamp b.

[0010] The number of the vertical rods a is 2, and the two vertical rod a compression springs are passed through the vertical rod a, and the vertical rod b is passed through between the two vertical rods a.

[0011] Compared with the prior art, the ingenious snap-on and release functions of the rebounder of the present invention make the holding operation very convenient. In addition, the built-in spring structure enables the upper and lower clamps to have a certain holding ability, and the middle groove design of the top clamp makes the holding more secure. It can not only quickly realize the electrical testing function through the electrical testing contacts, but also continuously test the electricity to avoid reverse power supply and cause safety accidents.

DETAILED DESCRIPTION

[0020] As shown in the accompanying drawings, the present invention comprises an upper clamp 1 and a lower clamp 2, the upper clamp 1 comprises a vertical rod a3, and the two ends of the vertical rod a3 are respectively fixed with a top plate clamp a4 and a bottom plate a5; the lower clamp 2 comprises a top plate clamp b6 and a bottom plate b7, and a vertical rod b8 is fixed between the top plate clamp b6 and the bottom plate b7. The top plate clamp b6 and the bottom plate b7 of the lower clamp 2 are both penetrated on the vertical rod a3, so that the upper clamp 1 and the lower clamp 2 slide up and down, so that a wire clamp is formed between the top plate clamp a4 and the top plate clamp b6, thereby firmly clamping the wire, the vertical rod b8 passes through the bottom plate b7 and the bottom plate a5, and an electroscope 9 is fixed at the lower end of the vertical rod b8, and a translation device is provided between the bottom plate a5 and the bottom plate b7, and the translation device makes the bottom plate a5 and the bottom plate b7 move relative to or back to back, thereby driving the top plate clamp a4 and the top plate clamp b6 to move, and fixing the electroscope 9 between the top plate clamp a4 and the top plate clamp b6.

[0021] The translation device includes a rebounder device 10, which can not only lock the upper clamp 1 and the lower clamp 2 together, but also make the upper clamp 1 and the lower clamp 2 bounce apart. The rebounder device 10 includes a rebounder body 12 and a rebounder butt 13, and the lower end of the rebounder body 12 is provided with a clamping arm that can clamp the butt 13 together. The rebounder body 12 is fixed to the lower side of the bottom plate b7, and the rebounder butt 13 is fixed to the upper side of the bottom plate a5. The top plate clamp a4 of the upper clamp 1 and the top plate clamp b6 of the lower clamp 2 are pulled apart, and the butt 13 is inserted into the rebounder body 12. Inside the clamp arm, the clamp arm of the rebounder body 12 is fixed together with the bumper 13, so that an electric wire channel is formed between the top plate clamp a4 and the top plate clamp b6 of the lower clamp 2, which is convenient for placing the electric wire between the top plate clamp a4 and the top plate clamp b6. A stopper is horizontally fixed on the vertical rod a3 of the upper clamp 1, and a compression spring is provided between the stopper and the top plate clamp b6. One end of the compression spring is fixed on the stopper, and the other end of the compression spring is fixed on the upper plate of the lower clamp 2, so that there is always a certain holding force between the top plate clamp a4 of the upper clamp 1 and the top plate clamp b6 of the lower clamp 2 at any time.

[0022] A tester operating rod 15 is fixed to the tester 9, and the tester operating rod 15 pulls the tester 9 to move, so that the rebound device 10 is locked or unlocked.

[0023] The translation device includes an electric telescopic rod 16, one end of which is fixed on the bottom plate a5, and the other end is fixed on the bottom plate b7. When the electric telescopic rod 16 is turned on, the electric telescopic rod 16 contracts, driving the bottom plate a5 and the bottom plate b7 to move toward each other, so that the top plate clamp a4 and the top plate clamp b6 move away from each other, and a gap is formed between the top plate clamp a4 and the top plate clamp b6, which is convenient for placing the device to be tested. When the electric telescopic rod 16 is turned on, the electric telescopic rod 16 extends, so that the top plate clamp a4 and the top plate clamp b6 move relative to each other, thereby pressing the device to be tested.

[0024] There are semi-elliptical grooves 14 on the lower side of the top plate clamp a4 and the top plate clamp b6, and the semi-elliptical grooves 14 make the cylindrical wire more firmly supported.

[0025] There are two vertical rods a3, and two vertical rod a3 compression springs are passed through the vertical rod a3, and the vertical rod b8 is passed between the two vertical rods a3, which enhances the stability of the relative movement of the upper jaw 1 and the lower jaw 2.

[0026] The material of the upper jaw 1 is insulating plastic or rubber, and the material of the lower jaw 2 is conductive metal material.

[0027] It is worth noting that the rebound device 10 is a prior art, the JD.com item number is 25542660723, the product model is MC-37F, and this manual will not describe it in detail.

[0028] The working process of the present invention is as follows: pull the top plate clamp a4 and the top plate clamp b6 until the rebound device 10 is in the locking position, that is, insert the head 13 into the clamp arm of the rebound body 12, so that the upper clamp 1 and the lower clamp 2 are fixed, and the equipment to be tested is placed between the top plate clamp a4 and the top plate clamp b6, and pull the electroscope operating rod 15 downward, the rebound device 10 is unlocked, that is, the head 13 is separated from the clamp arm of the rebound body 12, and under the action of the compression spring, the upper clamp 1 drives the top plate clamp a4 to move downward until the equipment to be tested is clamped, and the ground wire can be hung at this time. When the electroscope 9 emits an alarm sound before hanging the ground wire, it means that the line is returning electricity, and the operation should be stopped immediately and reported to the dispatcher. If there is no alarm sound, it means that the line has not been returning electricity, and the ground wire can be hung; after hanging the ground wire, pull down the electroscope operating rod 15 again to the locking position of the rebounder, the rebounder is locked again, and the upper clamp 1 and the lower clamp 2 are fixed and opened a certain distance, and the electroscope 9 can be removed at this time.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
