Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulation operating rods, and more particularly to an anti-falling insulation operating rod for dismounting a drop-out fuse. BACKGROUND

[0002] At present, there are many high-voltage drop-out fuses on the pole in the distribution network, and the operation of the high-voltage drop-out fuses is very dangerous. If the operation is not skilled or the weather factor affects, the high-voltage drop-out fuse is likely to fall from the insulation operating rod when being put on or taken off, which is dangerous to the operator.

[0003] In addition, when the existing drop-out fuse is removed through the insulation operating rod, the distance of the insulation operating rod is already very long, and the insulation operating rod has a certain weight, so that the operator is very laborious when lifting or putting down the insulation operating rod due to the moment, especially when dismounting the drop-out fuse, the insulation operating rod with the drop-out fuse at the top end needs to be slowly laid horizontally, which makes the operation more laborious.

[0004] Chinese Patent No. CN210866093U, published on June 26, 2020, discloses an insulation operating rod for a high-voltage drop-out fuse, which comprises a first rod body, a second rod body, a clamping structure, and an adjustable control structure. The first rod body is provided with a holding part near the bottom, and the holding part is provided with an anti-slip band. The first rod body is provided with an installation cavity inside. The second rod body is inserted into the first rod body. The first rod body is provided with a fastening knob near the connection with the second rod body. The clamping structure is fixedly installed on the top of the second rod body. The above-mentioned application can prevent falling through the cooperation between the clamping head and the handle. However, in actual use, it is very difficult to operate the clamping head through the handle due to the long distance of the operating rod. In addition, if the clamping head does not clamp the drop-out fuse tightly, the drop-out fuse is still likely to fall. SUMMARY

[0005] The present application overcomes the deficiency of the prior art that the insulation operating rod lacks a protective device when installing or dismounting the drop-out fuse, which makes the drop-out fuse likely to fall and cause danger when being replaced or dismounted. The present application provides an anti-falling insulation operating rod for dismounting a drop-out fuse, which can effectively prevent the danger caused by the falling of the drop-out fuse when installing or dismounting the drop-out fuse.

[0006] In order to solve the above technical problems, the present application adopts the following technical scheme: an anti-falling insulation operating rod for disassembling and assembling a drop-out fuse, comprising: a first rod body and a second rod body connected with the first rod body, a top end of the first rod body is provided with an operating head matched with the drop-out fuse, a falling-preventing device is arranged below the operating head of the first rod body, the falling-preventing device comprises a collecting cylinder and a fixing ring arranged in the circumferential direction of the opening of the collecting cylinder.

[0007] The present application sets the collecting cylinder below the operating head, so that the operating head can play a good protection role when disassembling or assembling the drop-out fuse, when the drop-out fuse falls due to an accident, the drop-out fuse can fall into the collecting cylinder, preventing the falling of the drop-out fuse from causing danger to the operator below, and meanwhile, the new drop-out fuse can also be prevented from being damaged due to falling during installation; and since the weight of the collecting cylinder is light, the burden of the operator can be reduced, and the work efficiency is not affected.

[0008] Preferably, the fixing ring comprises a fixing belt, one end of the fixing belt is provided with a plug, and the other end of the fixing belt is linearly arranged with a plug hole, and the plug is matched with the plug hole.

[0013] When the drop-out fuse falls into the collecting cylinder, the drop-out fuse is on the top of the insulating operating rod, so that the insulating operating rod needs to be slowly laid horizontally to take out the drop-out fuse in the collecting cylinder, but during the horizontal laying of the insulating operating rod, the drop-out fuse is placed in the top of the collecting cylinder, so that a very large force is needed to stably lay the insulating operating rod horizontally, and at this time, the strength of the operator is also consumed a lot, so that the insulating operating rod may fall during the horizontal laying process due to insufficient force, and then secondary danger occurs; therefore, the sliding device is arranged, so that when the drop-out fuse is placed in the collecting cylinder, the collecting cylinder can slide down along the insulating operating rod, so as to reduce the operation difficulty of taking out the drop-out fuse in the collecting cylinder by horizontally laying the insulating operating rod.

[0020] When the collection cylinder is empty, the side wall of the limiting rod abuts against the clamping rod, so that the other end of the clamping rod away from the limiting rod abuts against the clamping wheel, so that the clamping wheel cannot rotate, so that the pulley connected with the clamping wheel through the rotating shaft also stops rotating, so that the sliding sleeve can be clamped on the insulating operating rod and cannot fall; when the drop-out fuse falls into the collection cylinder, the limiting ring groove on the limiting rod moves to the position corresponding to the clamping hole through the gravity of the drop-out fuse, so that the clamping rod abuts against the limiting ring groove through the action force of the first reset spring, so that the clamping rod away from the limiting ring groove is separated from the clamping wheel, so that the clamping wheel is separated from the limitation of the clamping rod, so that the pulley connected with the clamping wheel through the rotating shaft can rotate, so that the sliding sleeve can slide along the insulating operating rod, so that the collection cylinder with the drop-out fuse can slide along the insulating operating rod, so as to reduce the operation difficulty of horizontally placing the insulating operating rod to take out the drop-out fuse in the collection cylinder, and the purpose of saving labor is achieved.

DETAILED DESCRIPTION

[0041] The technical solutions of the present application will be further described below with specific examples and in conjunction with the drawings:

[0042] Example 1: Refer to Figures 1 to 2 As shown, an anti-falling insulation operating rod for disassembling a falling type fuse includes a first rod body 1 and a second rod body 2 connected with the first rod body 1. The top end of the first rod body 1 is provided with an operating head 11 matched with the falling type fuse. The first rod body 1 is provided below the operating head 11 with an anti-falling device 3 connected with the first rod body 1 through a steel wire 34. The position of a collecting cylinder 31 below the operating head 11 can be conveniently adjusted through the steel wire 34. The anti-falling device 3 includes the collecting cylinder 31 and a fixing ring arranged in the circumferential direction of the opening of the collecting cylinder 31.

[0043] The fixing ring includes a fixing belt 32 supporting the opening of the collecting cylinder 31. One end of the fixing belt 32 is provided with a latch 33, and the other end of the fixing belt 32 is linearly arranged with a plurality of insertion holes 321. The latch 33 is matched with the insertion holes 321. Through the matching of the latch 33 with different insertion holes 321, the size of the opening of the collecting cylinder 31 can be adjusted to adapt to the installation of falling type fuses of different sizes.

[0044] In order to conveniently connect the first rod body 1 with the second rod body 2, a connecting hole 21 is arranged on the second rod body 2. As shown, a connecting head 12 matched with the connecting hole 21 is arranged on the first rod body 1. The connecting hole 21 and the connecting head 12 are threadedly connected. The circumferential direction of the connecting head 12 is provided with a circular arc transition section 13 matched with the end face of the connecting head 12.

[0045] At the same time, in order to ensure the insulation distance of the operator from the high-voltage fuse during operation, a guard ring 4 is arranged in the circumferential direction of the second rod body 2. During operation, the operator is strictly prohibited from having hands beyond the upper end of the guard ring 4.

[0046] In use, the embodiment is divided into two steps of installing and dismounting the drop-out fuse. When installing the drop-out fuse, the end of the drop-out fuse is matched with the operating head 11 at the end of the insulating operating rod, so that the drop-out fuse is hung on the operating head 11, and the shape of the steel wire 34 is adjusted, so that the drop-out fuse is hung in the collecting cylinder 31. When the drop-out fuse is not installed in place and falls, the drop-out fuse can fall into the collecting cylinder 31, preventing the falling of the drop-out fuse from causing danger to the operator below, and also preventing the new drop-out fuse from being damaged due to falling during installation. When the drop-out fuse needs to be dismounted, first, one end of the drop-out fuse is dismounted from the high-voltage power grid, so that it can be hung on the high-voltage power grid through the connection of the other end with the high-voltage power grid. Then, the collecting cylinder 31 is sleeved around the drop-out fuse from below, so that the collecting cylinder 31 is sleeved on the drop-out fuse. Then, the drop-out fuse is dismounted from the power grid through the operating head 11. The collecting cylinder 31 prevents the falling of the drop-out fuse from causing danger to the operator below. The collecting cylinder 31 is made of flexible plastic. The flexible plastic can reduce the weight of the collecting cylinder 31. In order to facilitate the drainage of water in the collecting cylinder 31, a water leakage hole can be arranged below the collecting cylinder 31. The flexible plastic structure can conveniently adjust the size of the opening of the collecting cylinder 31.

[0054] In the embodiment, when the drop-out fuse is installed or removed, after the drop-out fuse falls into the collecting cylinder 31, the drop-out fuse is on the top of the insulating operating rod, so that the insulating operating rod needs to be slowly laid horizontally to take out the drop-out fuse in the collecting cylinder 31, but during the horizontal laying process of the insulating operating rod, the collecting cylinder 31 at the top is provided with the drop-out fuse, which makes it need a lot of effort to horizontally lay the insulating operating rod stably, and at this time, the operator's strength is also consumed a lot because the insulating operating rod has been lifted for a long time, so that the insulating operating rod may fall during the horizontal laying process due to insufficient strength, and further secondary danger may occur; therefore, the sliding device 5 is arranged, so that when the drop-out fuse is placed in the collecting cylinder 31, the collecting cylinder 31 can slide down along the insulating operating rod to reduce the operation difficulty of taking out the drop-out fuse in the collecting cylinder by horizontally laying the insulating operating rod.

[0055] The working principle of the embodiment is as follows: when the collecting cylinder 31 is empty, the side wall of the limiting rod 58 abuts against the clamping rod 56, the other end of the clamping rod 56 away from the limiting rod 58 abuts against the clamping wheel 54, the clamping wheel 54 cannot rotate, the pulley 52 connected with the clamping wheel 54 through the rotating shaft 53 also stops rotating, and the sliding sleeve 51 can be clamped on the insulating operating rod and cannot fall; when the drop-out fuse falls into the collecting cylinder 31, the limiting rod 58 is driven to move downward by the steel wire 34 under the action of gravity of the drop-out fuse, the limiting ring groove 581 at the upper end of the limiting rod 58 corresponds to the position of the clamping hole 512, the clamping rod 56 abuts against the limiting ring groove 581 under the action of the first reset spring 57, the clamping rod 56 away from the limiting ring groove 581 is separated from the clamping wheel 54, the clamping wheel 54 is separated from the limiting of the clamping rod 56, the pulley 52 connected with the clamping wheel 54 through the rotating shaft 53 can rotate, the sliding sleeve 51 can slide along the insulating operating rod, and the collecting cylinder 31 with the drop-out fuse can slide along the insulating operating rod, so that the operation difficulty of laying the insulating operating rod horizontally to take out the drop-out fuse in the collecting cylinder 31 is reduced, and the purpose of saving labor is achieved.

[0056] Embodiment 3: refer to Figure 4 As shown in the figure, the embodiment is similar to the structure of embodiment 2, and the difference lies in that the circumferential direction of the clamping wheel 54 is provided with a plurality of clamping grooves 541 parallel to the axial direction of the clamping wheel 54, and the end face of the clamping rod 56 close to the clamping wheel 54 is provided with a circular arc surface matched with the clamping wheel 54, and the circular arc surface is provided with a convex strip 562 matched with the clamping groove 541. The cooperation between the convex strip 562 and the clamping groove 541 can make the clamping and limiting effect of the clamping rod 56 on the clamping wheel 54 better.

[0058] In this embodiment, the reset spring 59 can prevent the limiting rod 58 from sliding in the limiting hole 514 due to small fluctuations, thereby improving the stability of the limiting rod 58 in the limiting hole 514. It should be noted that when the sliding sleeve 51 slides down along the insulating operating rod, the falling type fuse in the collecting cylinder 31 is taken out, and the second reset spring 59 cannot push the limiting convex ring 582, so that the second reset spring 59 cannot push the limiting rod 58 to move upward, so that the reset ring groove 515 is separated from the clamping rod 56, and only by applying additional force can the reset ring groove 515 be separated from the clamping rod 56; so that when the sliding sleeve 51 slides to the lower end of the insulating operating rod, the sliding sleeve 51 can be conveniently reset to the top end of the insulating operating rod, and when the sliding sleeve 51 is reset to the top end of the insulating operating rod, the limiting rod 58 is applied by hand or other means. Force, the reset ring groove 515 is separated from the clamping rod 56, so that the limiting rod 58 can push the clamping rod 56 to abut against the clamping wheel 54, thereby realizing the rotation of the pulley 52, and achieving the purpose of fixing the sliding sleeve 51.
