Description

Technical Field

[0001] This utility model relates to the field of shielding covers, and in particular to an integrated shielding cover for a tension clamp and a suspension insulator. Background Technology

[0002] An integrated shielding cover for tension clamps and suspension insulators is a device used in live-line electrical work to simultaneously provide insulation shielding or isolation protection for tension clamps and suspension insulators. It is typically made of insulating material, and its overall design completely encloses the tension clamp and suspension insulator. For example, it may employ a structure similar to an arc-shaped shielding plate with connecting plates and hinges on both sides. The arc-shaped shielding plate has semi-circular baffles on both the front and rear sides, forming a complete shielding cover through connections and snap-fits. This prevents workers from directly contacting live parts and risking electric shock, ensuring the safety of live-line work. This type of shielding cover is commonly used in power systems with voltage levels of 10kV and below, and has advantages such as scientific design, simple structure, convenient operation, and good shielding effect.

[0003] While existing technologies, such as integrated shielding covers for tension clamps and suspension insulators, can meet the basic insulation protection requirements for live-line electrical work, some problems still exist. Some integrated shielding covers use a structure where the arc-shaped shielding plate is connected by a connecting plate and a hinge. The buckle design is relatively simple, and in complex outdoor environments or under the shaking of operators, it is easy for it to loosen or even fall off, reducing the insulation protection effect and posing a safety hazard.

[0004] Furthermore, the sealing at the junction of the semi-circular baffle and the arc-shaped shield is poor, allowing rainwater, dust, and other foreign objects to easily enter the shield, affecting the insulation performance of the tension clamp and suspension insulator. In addition, the installation and disassembly process of the existing shield is relatively cumbersome, requiring multiple operations of the clips or connectors, which increases the working time and labor intensity, and is not conducive to the efficient implementation of live-line work. Utility Model Content

[0005] The main purpose of this utility model is to provide an integrated shielding cover for tension clamps and suspension insulators, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An integrated shielding cover for a tension clamp and a suspension insulator includes a suspension insulator body and a tension clamp body connected to the suspension insulator body. The suspension insulator body and the tension clamp body share a shielding cover body consisting of an upper shielding cover and a lower shielding cover. The upper and lower shielding covers are divided into a tension clamp shielding section and a suspension insulator shielding section, respectively. The upper and lower shielding covers are fixedly connected together by a connecting structure, which includes a fixed plate, a movable plate, a locking plate, and a knob. The fixed plate is fixedly connected to the outer wall of the upper shielding cover, and the movable plate is movably connected to the top surface of the fixed plate via a slider on its bottom surface. The locking plate is fixedly connected to the side wall of the movable plate. The knob is movably connected to the side plate on the top surface of the fixed plate via a protruding ring on the side wall, and the movable plate is also movably connected to the knob via a screw on another side wall. The lower shielding cover is fixedly connected to the upper shielding cover via an L-shaped block on its side wall.

[0008] Preferably, the tension clamp shielding part and the suspension insulator shielding part are designed as an integral unit and form an upper shielding cover and a lower shielding cover, and the upper shielding cover and the lower shielding cover are made of insulating material.

[0009] Preferably, the shapes of the tension clamp shielding part and the suspension insulator shielding part are compatible with the suspension insulator body and the tension clamp body.

[0010] Preferably, a set of symmetrical L-shaped blocks are fixedly installed on both sides of the outer wall of the lower shield, and the vertical sidewall of the L-shaped blocks is provided with a notch.

[0011] Preferably, a set of fixing plates are fixedly installed on both sides of the outer wall of the upper shield, and the top surface of the fixing plate is provided with an insertion port, and the top surface of the fixing plate is also provided with a sliding port on one side of the insertion port.

[0012] Preferably, the side plate is fixedly installed on the top surface of the fixing plate, and a connection hole is provided on the side wall of the side plate.

[0013] Preferably, the side plate also has a convex annular groove on its side wall.

[0014] Preferably, a convex ring is fixedly installed on the inner side wall of the knob, and the convex ring is movably installed in the convex ring groove. A screw hole is also provided on the side wall of the knob. A retaining plate is fixedly installed on the inner side wall of the movable plate, and a slider is fixedly installed on the bottom surface of the movable plate. The slider is movably installed in the sliding opening. The screw is fixedly installed on the outer side wall of the movable plate and passes through the connecting hole and is threadedly connected to the screw hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this utility model, the connection structure provides a stronger fastening force compared to the traditional simple snap-fit ​​connection method. When the knob is rotated, the screw drives the movable plate to move, and the locking plate can firmly lock the L-shaped block of the lower shield, effectively preventing the shield from loosening or falling off in complex outdoor environments or during operation. This ensures continuous insulation protection for tension clamps and suspension insulators, reduces the risk of electric shock to workers, and improves the safety of live-line work.

[0017] The tension clamp shielding section of the upper and lower shielding covers is integrated with the suspension insulator shielding section, and its shape closely matches the tension clamp body and suspension insulator body, reducing connection gaps. Simultaneously, during the tightening process, the connection structure ensures a tight fit between the upper and lower shielding covers. Combined with the L-shaped block and clamping plate design, this effectively prevents rainwater, dust, and other foreign objects from entering the shielding cover, preventing a decrease in insulation performance of the tension clamp and suspension insulator due to foreign object intrusion, extending equipment lifespan, and ensuring stable operation of the power system.

[0018] This makes the installation and disassembly of the integrated shielding cover simple and efficient. Operators only need to rotate the knob to quickly connect and separate the upper and lower shielding covers, without having to operate multiple clips or connectors as required by traditional shielding covers. This greatly saves working time, reduces labor intensity, and can effectively improve the efficiency of live-line work, especially suitable for time-sensitive work scenarios such as emergency repairs.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 - Figure 5 As shown, an integrated shielding cover for a tension clamp and a suspension insulator includes a suspension insulator body 1 and a tension clamp body 2 connected to the suspension insulator body 1. The suspension insulator body 1 and the tension clamp body 2 are jointly provided with a shielding cover body 3 consisting of an upper shielding cover 4 and a lower shielding cover 5. The upper shielding cover 4 and the lower shielding cover 5 are divided into a tension clamp shielding part 7 and a suspension insulator shielding part 8, respectively. The upper shielding cover 4 and the lower shielding cover 5 are fixedly connected together by a connecting structure 6, which includes a fixing plate 11. The upper shield 4 has a fixed plate 11 fixedly connected to the outer wall of the upper shield 4, and the movable plate 17 is movably connected to the top surface of the fixed plate 11 through the slider 19 on the bottom surface. The clamping plate 18 is fixedly connected to the side wall of the movable plate 17. The knob 21 is movably connected to the side plate 14 on the top surface of the fixed plate 11 through the protruding ring 22 on the side wall. The movable plate 17 is also movably connected to the knob 21 through the screw 20 on the other side wall. The lower shield 5 is fixedly connected to the upper shield 4 through the L-shaped block 9 on the side wall.

[0027] like Figure 1 As shown, the tension clamp shielding part 7 and the suspension insulator shielding part 8 are designed as a single unit and form the upper shielding cover 4 and the lower shielding cover 5. The upper shielding cover 4 and the lower shielding cover 5 are made of insulating material. The shapes of the tension clamp shielding part 7 and the suspension insulator shielding part 8 fit the suspension insulator body 1 and the tension clamp body 2. The tension clamp shielding part 7 and the suspension insulator shielding part 8 adopt an integrated molding process to jointly form the upper shielding cover 4 and the lower shielding cover 5. The shapes are precisely matched with the outer contours of the suspension insulator body 1 and the tension clamp body 2, reducing the splicing gaps of the shielding cover body 3, reducing the risk of foreign object intrusion, and improving the overall sealing performance. At the same time, the integrated structure simplifies the installation steps, reduces the shielding blind spots caused by the misalignment of the separate parts, and enhances the reliability of insulation protection.

[0028] like Figure 3 As shown, a set of symmetrical L-shaped blocks 9 are fixedly installed on both sides of the outer wall of the lower shield 5, and a slot 10 is provided on the vertical side wall of the L-shaped block 9. The L-shaped blocks 9 are symmetrically arranged on both sides of the outer wall of the lower shield 5, and the slot 10 is provided on the vertical side wall for cooperating with the card plate 18 of the upper shield. During installation, the L-shaped blocks are inserted into the slot 12 of the fixing plate 11 of the upper shield to form a pre-positioning structure.

[0029] like Figure 4As shown, a set of fixing plates 11 are fixedly installed on both sides of the outer wall of the upper shield 4, and the top surface of the fixing plate 11 is provided with an insertion port 12. The top surface of the fixing plate 11 and the side of the insertion port 12 are also provided with a sliding port 13. The insertion port 12 is used to accommodate the L-shaped block of the lower shield, and the sliding port 13 provides a sliding track for the slider 19 at the bottom of the movable plate 17, so that the movable plate can move laterally along the sliding port.

[0030] like Figure 4 As shown, the side plate 14 is fixedly installed on the top surface of the fixed plate 11, and a connecting hole 15 is provided on the side wall of the side plate 14. A convex annular groove 16 is also provided on the side wall of the side plate 14. The connecting hole 15 is used for the screw 20 to pass through, so as to realize the transmission connection between the movable plate 17 and the knob 21. The convex annular groove 16 cooperates with the convex ring 22 on the inner side of the knob 21, allowing the knob 21 to rotate in the horizontal direction while restricting its axial displacement.

[0031] like Figure 4 As shown, a convex ring 22 is fixedly installed on the inner side wall of the knob 21, and the convex ring 22 is movably installed in the convex ring groove 16. A screw hole 23 is also provided on the side wall of the knob 21. A retaining plate 18 is fixedly installed on the inner side wall of the movable plate 17, and a slider 19 is fixedly installed on the bottom surface of the movable plate 17. The slider 19 is movably installed in the sliding opening 13. The screw 20 is fixedly installed on the outer side wall of the movable plate 17 and passes through the connecting hole 15 and is threadedly connected to the screw hole 23. When the knob 21 is rotated, the screw 20 drives the movable plate 17 to slide along the sliding opening 13, so that the retaining plate 18 is inserted into or released from the retaining slot 10 of the lower shield, thereby realizing the locking and unlocking of the shield body 3.

[0032] The specific operating principle of this integrated shielding cover for tension clamps and suspension insulators is as follows:

[0033] First, place the lower shielding cover 5 under the lower part of the suspension insulator body 1 and the tension clamp body 2. Align the L-shaped blocks 9 symmetrically arranged on both sides of the outer wall of the lower shielding cover 5 with the insertion slots 12 on the top surface of the fixing plate 11 on the outer wall of the upper shielding cover 4. Insert the L-shaped blocks 9 into the insertion slots 12 to complete the initial positioning. At this time, the L... The slot 10 on the vertical side wall of the L-shaped block 9 corresponds to the position of the movable plate 17 of the upper shield 4. Then, the operator rotates the knob 21 installed on the outer wall of the side plate 14 on the top surface of the fixed plate 11. The convex ring 22 fixedly installed on the inner side wall of the knob 21 rotates in the convex ring groove 16 opened on the side wall of the side plate 14. Since the side wall of the knob 21 has a screw hole 23 and is threadedly connected to the screw 20 fixedly installed on the outer side wall of the movable plate 17, the rotational motion of the knob 21 is converted into the linear motion of the movable plate 17 through the screw 20. During this process, the slider 19 fixedly installed on the bottom surface of the movable plate 17 slides in the sliding opening 13 opened on the top surface of the fixed plate 11, driving the clamping plate 18 fixed on the side wall of the movable plate 17 to move towards the L-shaped block 9 until the clamping plate 18 is engaged with the L-shaped block 9. The upper shield 4 and the lower shield 5 are securely connected together within the slot 10 of the block 9. During use, the upper shield 4 and the lower shield 5, composed of the tension clamp shield 7 and the suspension insulator shield 8, effectively prevent the intrusion of rainwater, dust, and other foreign objects by means of their shape design that fits the suspension insulator body 1 and the tension clamp body 2, and the tight fit achieved by the connecting structure 6, ensuring the insulation protection effect. When disassembly is required, the operator rotates the knob 21 in the opposite direction, and the screw 20 drives the movable plate 17 to move in the opposite direction, so that the clamping plate 18 moves from L... When the upper shield 4 and lower shield 5 are disengaged from the latch 10 of the block 9, they can be separated, enabling quick disassembly. This makes the installation and disassembly of the integrated shield simple and efficient. Operators only need to rotate the knob to quickly connect and separate the upper and lower shields, eliminating the need for multiple operations of multiple clips or connectors as with traditional shields. This greatly saves working time, reduces labor intensity, and effectively improves the efficiency of live-line work, making it especially suitable for time-sensitive work scenarios such as emergency repairs.
