Description

Technical Field

[0001] This utility model relates to the field of insulating shields, and in particular to a modular insulating shield. Background Technology

[0002] With the rapid development of the power grid, power corridors are becoming increasingly scarce, and the number of multi-circuit or compact transmission lines on the same tower is increasing. When performing live work on towers, it is common to encounter situations where the safety distance is too small, especially when working on the lower crossarm. Often, there is an upper conductor above the worker. Taking a 110kV double-circuit line on the same tower as an example, the distance between the upper and lower crossarms is 3.5m. After deducting the length of the 1.3m insulator string, the safety distance for a 1.7m tall worker standing on the lower crossarm is only 0.5m, which is far less than the 1.0m safety distance. If only safety monitoring is provided without insulation protection, there will be safety hazards.

[0003] The related technology includes shielding sections located at both ends and a fixing section connecting the two shielding sections; the shielding section includes an upper insulating section with a semi-circular cross-section, an inner inclined section connected to both ends of the upper insulating section, and a vertical section connected to the bottom end of the inner inclined section; the fixing end includes an upper fixing plate with a semi-circular cross-section, a lower fixing plate located in the upper fixing plate and with a semi-circular cross-section, a tie rod connecting the outer surface of the lower fixing plate and the inner surface of the upper fixing plate, and a movable plate with the same shape and size as the lower fixing plate and arranged opposite to the lower fixing plate; the fixing end also includes a fixing rope A and a fixing rope B, with fixing rope A connecting one end of the movable plate to one end of the upper fixing plate, and fixing rope B connecting the other end of the movable plate.

[0004] Although this technology can shield the conductor, the lower part of the shielding section is open, so the conductor is not completely sealed. This still poses a safety hazard when people approach the conductor, which makes it difficult to achieve proper insulation and reduces the effectiveness of the conductor's insulation.

[0005] Therefore, it is necessary to provide a modular insulating shield to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a modular insulating shield.

[0007] This utility model provides a modular insulating shield, comprising: a shield body, a cover plate hinged to the bottom end of the shield body, rotating plates fixed to both ends of one side of the cover plate, a pull rod hinged to one end of each of the two rotating plates, a connecting seat hinged to one end of each of the two pull rods, the two connecting seats being fixedly connected by a connecting plate, and a pull rope fixed to the middle of the top end of the connecting plate.

[0008] Two reset components are respectively disposed between the two connectors and the shield body, and are used to drive the elastic movement of the connectors;

[0009] A connecting component, which is disposed between the shielding cover body and the cover plate, is used to connect the shielding cover body and the cover plate.

The first support plate and the second support plate are connected by an elastic component.

[0013] Preferably, the guide assembly includes a first guide plate hinged to the bottom end of the arc-shaped clamping plate, and a second guide plate hinged to the inner wall of the shielding cover body is inserted through the bottom end of the first guide plate.

[0014] Preferably, the elastic component includes a second slider fixedly disposed on both sides of the second support plate, and a second slide groove for sliding of the second slider is provided on both sides of the inner wall of the first support plate, and both second slide grooves are elastically connected to the second slider by a second spring.

[0015] Compared with related technologies, the modular insulating shield provided by this utility model has the following beneficial effects:

[0016] 1. A modular insulating shielding cover based on an embodiment of this application, when insulating and sealing a conductor, the operator first manually pulls the pull rope upwards. The pull rope drives the connecting plate upwards, which in turn drives the two connecting seats to move upwards synchronously. The two connecting seats synchronously pull the two pull rods, which in turn synchronously pull the rotation of the two rotating plates, thereby rotating the cover plate and opening the bottom of the shielding cover body. Then, the shielding cover body is placed over the conductor. The operator then releases the pull rope. At this time, under the elastic action of the reset component, the connecting seats are driven to reset downwards. The connecting seats drive the pull rods to reset, and the pull rods drive the rotating plates to reset, thereby resetting the cover plate. The cover plate then covers the bottom of the shielding cover body, and with the cooperation of the connecting component, the cover plate is connected to the shielding cover body. This completely seals the conductor, facilitating sufficient insulation and isolation of the conductor and improving the insulation effect of the conductor.

[0017] 2. A modular insulating shielding cover based on an embodiment of this application, when the shielding cover body is placed over the conductor, with the cooperation of the guide component, the conductor can be guided between two arc-shaped clamps. Then, under the elastic action of the elastic component, the second support plate is driven to move elastically. The second support plate drives the arc-shaped clamps to move elastically. In this way, with the cooperation of the two arc-shaped clamps, the conductor can be clamped, thereby fixing the shielding cover body and preventing the shielding cover body from sliding on the conductor. This facilitates the shielding cover body to insulate and isolate the conductor at a designated position, improving the insulation effect of the conductor. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 5 A modular insulating shield includes: a shield body 1, a cover plate 2 hinged to the bottom end of the shield body 1, rotating plates 3 fixed to both ends of one side of the cover plate 2, a pull rod 4 hinged to one end of each of the two rotating plates 3, a connecting seat 5 hinged to one end of each of the two pull rods 4, the two connecting seats 5 being fixedly connected by a connecting plate 6, and a pull rope 7 fixed to the middle of the top of the connecting plate 6.

[0026] Two reset components 8 are respectively disposed between the two connecting seats 5 and the shield body 1, and are used to drive the elastic movement of the connecting seats 5;

[0027] The connecting component 9 is disposed between the shielding cover body 1 and the cover plate 2 for connecting the shielding cover body 1 and the cover plate 2.

[0028] In this embodiment, when insulating and sealing the wire, the operator first manually pulls the pull rope 7 upwards. The pull rope 7 drives the connecting plate 6 upwards, which in turn drives the two connecting seats 5 upwards synchronously. The two connecting seats 5 synchronously pull the two pull rods 4, which in turn synchronously pull the two rotating plates 3, thereby driving the cover plate 2 to rotate. This opens the bottom of the shielding cover body 1, which is then placed over the wire. The operator then releases the pull rope 7. At this time, under the elastic action of the reset component 8, the connecting seat 5 is driven to reset downwards. The connecting seat 5 drives the pull rods 4 to reset, and the pull rods 4 drive the rotating plates 3 to reset, thereby driving the cover plate 2 to reset. The cover plate 2 then covers the bottom of the shielding cover body 1. With the cooperation of the connecting component 9, the cover plate 2 is connected to the shielding cover body 1, thus completely sealing the wire, facilitating sufficient insulation and isolation of the wire, and improving the insulation effect of the wire.

[0029] In a further embodiment, such as Figure 2As shown, the reset assembly 8 includes a first slider 81 fixedly disposed on one side of the connecting seat 5, and a first groove 82 for sliding the first slider 81 is provided on one side of the shield body 1. The first groove 82 is elastically connected to the first slider 81 by a first spring 83.

[0030] In this embodiment, after the shielding cover body 1 is placed over the wire, the first slider 81 moves elastically under the elastic action of the first spring 83. The first slider 81 drives the connecting seat 5 to reset, the connecting seat 5 drives the pull rod 4 to reset, the pull rod 4 drives the rotating plate 3 to reset, thereby driving the cover plate 2 to reset, so that the cover plate 2 covers the bottom of the shielding cover body 1. In this way, the bottom of the shielding cover body 1 is sealed, thereby completely sealing the wire and facilitating the full insulation and isolation of the wire.

[0031] In a further embodiment, such as Figure 3 As shown, the connecting component 9 includes a connecting block 91 fixedly installed at the top of the cover plate 2, and a connecting groove 92 adapted to the connecting block 91 is provided on one side of the bottom end of the shield body 1.

[0032] In this embodiment, when the cover plate 2 closes the bottom of the shielding cover body 1, the connecting block 91 on the cover plate 2 is inserted into the connecting groove 92. In this way, with the cooperation of the connecting block 91 and the connecting groove 92, it is convenient to fully connect the cover plate 2 and the shielding cover body 1.

[0033] In a further embodiment, such as Figure 4 As shown, both sides of the inner wall of the shielding cover body 1 are provided with arc-shaped clamps 10. The two arc-shaped clamps 10 are respectively connected to the shielding cover body 1 through guide components 11. Both sides of the inner wall of the shielding cover body 1 are fixed with first support plates 12. A second support plate 13 fixed to the arc-shaped clamps 10 is inserted and connected to one side of the first support plate 12. The first support plate 12 and the second support plate 13 are connected by elastic components 14.

[0034] In this embodiment, when the shielding cover body 1 covers the wire, with the cooperation of the guide component 11, the wire can be guided between the two arc-shaped clamps 10. Then, under the elastic action of the elastic component 14, the second support plate 13 is driven to move elastically. The second support plate 13 drives the arc-shaped clamps 10 to move elastically. In this way, with the cooperation of the two arc-shaped clamps 10, the wire can be clamped, thereby fixing the shielding cover body 1 and preventing the shielding cover body 1 from sliding on the wire. This facilitates the shielding cover body 1 to insulate and isolate the wire at a designated position, improving the isolation effect of the wire.

[0035] In a further embodiment, such as Figure 4As shown, the guide assembly 11 includes a first guide plate 111 hinged to the bottom end of the arc-shaped clamping plate 10, and a second guide plate 112 hinged to the inner wall of the shielding cover body 1 at the bottom end of the first guide plate 111.

[0036] In this embodiment, when the shielding cover body 1 covers the wire, the wire can move along the first guide plate 111 and the second guide plate 112 with the cooperation of the first guide plate 111 and the second guide plate 112, thereby facilitating the guidance of the wire to the arc-shaped clamp 10.

[0037] In a further embodiment, such as Figure 5 As shown, the elastic component 14 includes a second slider 141 fixedly disposed on both sides of the second support plate 13. The inner walls of the first support plate 12 are provided with second slide grooves 142 for sliding of the second slider 141. Both second slide grooves 142 are elastically connected to the second slider 141 by a second spring 143.

[0038] In this embodiment, when the wire moves between the two arc-shaped clamps 10, the second spring 143 causes the second slider 141 to move elastically. The second slider 141 then causes the second support plate 13 to move elastically, which in turn causes the arc-shaped clamps 10 to move elastically. In this way, with the cooperation of the two arc-shaped clamps 10, the wire can be clamped, thereby fixing the shielding cover body 1 and preventing the shielding cover body 1 from sliding.

[0039] The working principle of the modular insulating shield provided by this utility model is as follows: When insulating and sealing the wire, the operator first manually pulls the pull rope 7 upwards. The pull rope 7 drives the connecting plate 6 upwards, which in turn drives the two connecting seats 5 upwards synchronously. The two connecting seats 5 synchronously pull the two pull rods 4, which in turn synchronously pull the two rotating plates 3, thereby driving the cover plate 2 to rotate. This opens the bottom of the shield body 1, and the shield body 1 is then placed over the wire. The operator then releases the pull rope 7. At this time, under the elastic action of the first spring 83, the first slider 81 moves elastically. The first slider 81 drives the connecting seat 5 to reset, which in turn drives the pull rods 4 to reset. The pull rods 4 drive the rotating plates 3 to reset, thereby driving the cover plate 2 to reset, so that the cover plate 2 covers the bottom of the shield body 1. In this way, the bottom of the shield body 1 is opened. The shielding cover 1 is partially enclosed, thus completely sealing the wire and facilitating full insulation of the wire, improving the insulation effect. When the shielding cover 1 is placed on the wire, the wire can move along the first guide plate 111 and the second guide plate 112 with the cooperation of the first guide plate 111 and the second guide plate 112, thus facilitating the guidance of the wire to the arc-shaped clamp 10. Then, under the elastic action of the second spring 143, the second slider 141 is driven to move elastically, which in turn drives the second support plate 13 to move elastically. The second support plate 13 then drives the arc-shaped clamp 10 to move elastically. In this way, with the cooperation of the two arc-shaped clamps 10, the wire can be clamped, thereby fixing the shielding cover 1 and preventing the shielding cover 1 from sliding on the wire. This facilitates the shielding cover 1 to insulate the wire at the designated position, improving the insulation effect of the wire.
