Description
Technical Field
[0001] The utility model relates to the technical field of insulator accessories in power plants, transformer substations and transmission lines of electric power systems, in particular to an insulator locking pin anti-drop cover. Background Art
[0002] In the transmission line insulator string, a locking pin is installed at the connection part of each insulator to prevent the connection part from sliding off when the line is affected by wind and the line is dancing. Transmission lines are very susceptible to the influence of external environment and climatic conditions. During line operation and maintenance, it is often found that the locking pins at the connection points of the insulators are dislodged or fall off. This hidden danger can easily cause the insulator to separate from the connection hardware, resulting in a line drop accident, causing regional power supply imbalance and causing significant production losses.
[0003] Insulators are subjected to the stress of the wires when they are suspended. It is difficult to reset or replace the locking pin after it comes out. Without removing the insulator, the locking pin cannot be reinstalled and opened. In this case, the insulator must be removed before it can be replaced to eliminate the hidden danger. This operation requires a lot of manpower and material resources, and there are problems such as long operation time and high operation risks. To address this problem, it is necessary to study how to better fix the locking pin on the insulator bowl to avoid it coming out or slipping. Utility Model Content
[0004] In order to overcome the problems existing in the related art, the utility model provides an insulator locking pin anti-drop cover, which can be firmly fixed on the insulator bowl head to prevent the locking pin installed on the insulator connecting part from falling out or slipping.

The rectangular opening end and the convex head end are respectively fixedly connected to the two ends of the clamp body.

[0025] The specific implementation methods disclosed in the present utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0026] like Figure 1 The figure shows an exemplary embodiment of the utility model disclosed in the disclosure. The utility model insulator locking pin anti-drop cover comprises a clamp body 10, a locking pin baffle 20 and a fastener 30. The clamp body 10 is provided with a fixing hole 11, and a locking pin baffle 20 is provided outside the fixing hole 11. The locking pin baffle 20 is fixedly connected to the clamp body 10. The clamp body 10 is sleeved on the insulator bowl head, and one end of the locking pin on the insulator bowl head passes through the fixing hole 11 and is resisted by the locking pin baffle 20. The clamp body 10 is fixed to the insulator bowl head by the fastener 30.
[0027] For example, Figure 1 , Figure 2As shown, in the exemplary embodiment disclosed in the present utility model, the locking pin baffle 20 is V-shaped, and the two V-shaped feet of the locking pin baffle 20 are fixedly connected to the clamp body 10, and the end of the locking pin extending out of the fixing hole 11 is covered by the locking pin baffle 20.
[0028] The utility model insulator locking pin anti-drop cover is provided with a fixing hole 11 on the clamp body 10, so that the end of the locking pin exposed on the insulator bowl head passes through the fixing hole 11, and the clamp body 10 can fit on the insulator bowl head, eliminate the influence of the locking pin exposed outside the insulator bowl head, better fix to the insulator bowl head, and prevent the clamp body 10 from falling off from the insulator bowl head. Then a locking pin baffle 20 is designed at the position of the fixing hole 11 of the clamp body 10, and the area of the locking pin baffle 20 facing the fixing hole direction is larger than the fixing hole, and the end of the locking pin extending out of the fixing hole can be completely covered. The locking pin baffle 20 is fixedly connected to the clamp body 10, resisting the locking pin protruding outward, and preventing it from falling out or slipping off. In this way, the entire insulator locking pin anti-drop cover structure is more compact, can be better fixed to the insulator bowl head, prevent the locking pin from falling out or slipping off, and play a better anti-drop effect.
[0029] Specifically, Figures 1 to 4 As shown, the locking pin baffle 20 is a rectangular metal sheet folded into a V shape, the length of the locking pin baffle 20 is 85-100 mm, the width of the locking pin baffle 20 is 20-40 mm, rivet holes 41 are provided at both ends of the locking pin baffle 20, and the locking pin baffle 20 is fixedly connected to the clamp body 10 through rivets 40. The length of the fixing hole 11 is 17-20 mm, the width of the fixing hole 11 is 8-10 mm, and the distance between the fixing hole 11 and one side of the clamp band is 10-20 mm. The angle between the locking pin baffle 20 and the fastener 30 relative to the central axis of the insulator bowl head is greater than 90 degrees.
[0030] The size of the fixing hole 11 should be determined according to the size of the insulator locking pin. It should not be too large, otherwise the locking pin will not be fixed, and too small, otherwise the locking pin will not be able to pass through. Figure 1 , Figure 3 As shown, the fixing hole 11 is 20 mm long, 10 mm wide, and 10 mm away from the bottom edge of the clamp band, which is suitable for allowing the R-type locking pin of the tension insulator bowl to pass through. Figure 2 The fixing hole 11 shown in the figure has a length of 17 mm, a width of 8 mm, and a distance of 10 mm from the bottom edge of the clamp band, which allows the R-type locking pin of the straight insulator cup to pass through. The distance between the locking pin baffle 20 and the fastener 30 should not be too close. When the insulator locking pin anti-drop cover is installed on the insulator cup, the operating space between the fastener 30 and the locking pin baffle 20 is small, which increases the difficulty of installation. Preferably, as Figure 1 , Figure 3As shown, the locking pin baffle 20 is located in the middle of the clamp body 10. Figure 2 As shown, the locking pin baffle 20 is located in the middle of the left clamp 12. The locking pin baffle 20 and the fastener 30 are spaced at an angle of 90 degrees relative to the central axis of the insulator bowl head. The locking pin baffle 20 and the fastener 30 are kept at a certain distance to facilitate the fastening operation of the fastener 30, and the insulator locking pin anti-drop cover is fixed to the insulator bowl head.
[0031] The locking pin baffle 20 is formed by folding a rectangular metal sheet, and can be folded into any shape, preferably into a V-shape. The inner side of the V-shaped tip faces the center of the fixing hole 11. The size of the locking pin baffle 20 should be able to completely cover the end of the locking pin extending out of the fixing hole 11, so that it can have a better anti-slip effect and prevent the locking pin from slipping off the edge of the locking pin baffle 20. Preferably, as Figure 4 As shown, the locking pin baffle 20 is 85 mm long and 20 mm wide.
[0032] For example, Figure 1 , Figure 3 As shown, it is a disclosed exemplary embodiment of the insulator locking pin anti-dropout cover of the utility model. The clamp body 10 of the insulator locking pin anti-dropout cover of the utility model is an integrally formed clamp band, and the two ends of the clamp band are respectively connected to the two ends of the fastener 30. The clamp band is a rectangular metal sheet, the length of the clamp band is 290-350mm, and the width of the clamp band is 30-40mm.
[0033] The clamp body 10 is an integrally formed clamp band, which is cut from a rectangular metal sheet and is easy to manufacture. Its size is determined according to the size of the insulator bowl to be mounted. Preferably, Figure 3 As shown, the length of the clamp band is 350 mm and the width is 40 mm, which is suitable for fixing on the bowl head of the tension insulator.
[0034] For example, the fastener 30 includes a rectangular open end 31 and a protruding end 32 that cooperate with each other. The rectangular open end 31 and the protruding end 32 are respectively fixedly connected to the two ends of the clamp body 10. The protruding end 32 extends into the opening 311 of the rectangular open end 31 and snaps back to clamp the rectangular open end 31.
[0035] Specifically, the rectangular opening end 31 and the convex end 32 are respectively formed integrally with the two ends of the clamp body 10, the opening 311 of the rectangular opening end 31 is 17-20 mm long and 3-5 mm wide, and the protrusion 322 of the convex end 32 is 25-40 mm long and 15-20 mm wide.
[0036] The main body of the insulator locking pin anti-drop cover of the utility model is composed of a rectangular metal sheet, with sufficient length reserved in the middle to be die-cast into a clamp band, and sufficient length is also reserved at both ends of the rectangular metal sheet for making a fastener 30. The fastener 30 is a rectangular opening 311 cut out of one end of the rectangular metal sheet, and a protrusion 322 cut out of the other end of the rectangular metal sheet. The protrusion 322 extends into the rectangular opening 311, and is folded and buckled to buckle the rectangular opening after being tightened, thereby fixing the clamp band to the insulator bowl head. Preferably, as Figure 3 As shown, the opening 311 of the rectangular opening end 31 is 20 mm long and 5 mm wide, and the width of the opening 311 is cut according to the thickness of the metal sheet. The protrusion 322 of the protruding head end 32 is 40 mm long and 50 mm wide, and the length of the protrusion 322 can be cut longer. When the clamp band is longer than the insulator bowl, the clamp band can be tightened to make the clamp band more firmly sleeved on the insulator bowl. The width of the protrusion 322 is cut accordingly according to the length of the opening 311 of the opening end.
[0037] Figure 2 FIG. 1 is a schematic diagram of the overall structure of another insulator locking pin anti-drop cover according to an exemplary embodiment. Figure 2 As shown, the clamp body 10 includes a left clamp 12 and a right clamp 13 , one end of the left clamp 12 and the right clamp 13 are hinged, and the other ends of the left clamp 12 and the right clamp 13 are respectively connected to the two ends of the fastener 30 .
[0038] Specifically, a fixing hole 11 is provided in the middle of the left clamp 12, a locking pin baffle 20 is provided outside the fixing hole 11, and a rotating shaft 50 passes through one end of the left clamp 12 and the right clamp 13, so that one end of the left clamp 12 and one end of the right clamp 13 are hinged, and the left clamp 12 and the right clamp 13 can rotate left and right with the rotating shaft 50 as the axis. The other ends of the left clamp 12 and the right clamp 13 are respectively connected to the two ends of the fastener 30. The split clamp can be installed and disassembled more easily, which is very useful in situations where the clamp needs to be replaced or adjusted frequently. If one of the components of the split clamp is damaged or fails, only the affected component can be replaced without replacing the entire clamp.
