Description

Technical Field

[0001] This utility model relates to the field of conductor clamping technology for relay protection, and in particular to a relay protection clamping device. Background Technology

[0002] In the safe and stable operation of power systems, relay protection devices play a crucial role. They can quickly issue alarm signals or commands when power equipment malfunctions or operates abnormally, promptly cutting off faulty circuits to prevent accidents from escalating and ensuring the reliable operation of the power system. Currently, to prevent the conductors on existing relay protection devices from becoming entangled, clamping devices are needed to limit the conductor movement.

[0003] For example, an existing patent (application number: CN202321801006.X) discloses a clamping device for power plant relay protection. It primarily addresses the problem that existing relay protectors, when using clamping devices, are inconvenient for limiting the wires, easily causing wire tangling during wiring or maintenance, thus increasing the difficulty of maintenance work. Furthermore, tangled wires can lead to increased temperature, increased wire loss, and even fire hazards. The proposed technical solution includes a relay protector and wire harnesses, with the wire harnesses connected to the relay protector. Multiple wire harnesses are fitted with positioning components for clamping and limiting the wire harnesses, and these positioning components are arranged in pairs. This utility model achieves separate arrangement of wire harnesses, avoiding mutual interference between them, and simultaneously achieves the purpose of clamping, limiting, and cleaning wire harnesses of different diameters, preventing impurities from affecting the transmission of wire harness signals.

[0004] While the existing clamping device can clamp and limit multiple wires, it requires rotating a large number of screws when separating the wires, which reduces the convenience and efficiency of the clamping device when separating the wires. Furthermore, when clamping the wires, the screws on both sides of the clamping ring must be rotated simultaneously to drive the clamping ring to perform the clamping movement, which makes the wire clamping and positioning work troublesome. Utility Model Content

[0005] This utility model relates to a relay protection clamping device, which solves the problem that existing clamping devices require rotating a large number of screws when separating from the wire, thus reducing the convenience and efficiency of separation. Furthermore, when clamping the wire, the screws on both sides of the clamping ring must be rotated simultaneously, which makes the wire clamping and positioning work troublesome.

[0006] In a first aspect, this utility model provides a relay protection clamping device, specifically comprising: a mounting base plate, wherein mounting holes are provided on both the left and right sides of the upper surface of the mounting base plate; a fixed clamping block is fixedly connected to the middle of the upper surface of the mounting base plate, and a rotating connecting block is fixedly connected to the left side of the upper surface of the mounting base plate, and a rotating clamping block is rotatably connected to the upper end of the rotating connecting block via a rotating shaft; a quick-limiting component is provided between the right end of the rotating clamping block and the right side of the upper surface of the mounting base plate; a rectangular sliding groove is uniformly provided on the bottom end surface of the rotating clamping block, and a movable clamping block is slidably connected within the rectangular sliding groove; the quick-limiting component includes a support block and a fixing block, wherein the support block is fixedly connected to the right end of the rotating clamping block, and two sliding grooves are provided on the right end surface of the support block, each sliding groove is provided with a spring guide rod, each spring guide rod is sleeved with a spring, and a sliding block is slidably connected to each sliding groove via the spring guide rod; a limit insertion hole is provided at the lower end of the opposite surface of the two sliding blocks; and two fixing blocks are provided, with a limit insertion rod fixedly connected to the upper part of the opposite surface of the two fixing blocks.

[0007] Furthermore, the upper end face of the rotating clamp is uniformly provided with threaded through holes communicating with the rectangular slide groove, and each rectangular slide groove has strip-shaped slide grooves on both the left and right sides inside.

[0008] Furthermore, the bottom end face of the support block has two strip-shaped openings, and the two strip-shaped openings are respectively connected to two sliding grooves.

[0009] Furthermore, a pinch plate is fixedly connected to the right end face of each sliding block, and anti-slip stripes are provided on the opposite sides of the two pinch plates.

[0010] Furthermore, when the quick-stopping component is in the stopping state, the stopping rod is inserted into the stopping hole, and the rotating clamp is in the closed state at this time.

[0011] Furthermore, a screw is rotatably connected to the middle of the upper end face of the movable clamping block, and the screw is threadedly connected to the threaded through hole, and a rotating handwheel is provided at the upper end of the screw; guide slides are provided on both the left and right sides of the movable clamping block, and the guide slides are slidably connected to the strip-shaped slide groove.

[0012] Furthermore, both the fixed clamping block and the movable clamping block have arc-shaped clamping openings on their clamping surfaces, and rubber anti-slip pads are provided inside the arc-shaped clamping openings.

[0013] This utility model provides a relay protection clamping device, which has the following beneficial effects:

[0014] This invention, through the cooperation of the rotating clamping block and the quick-stopping component, allows for easy separation of the clamping device from the wire when necessary. Simply pinch the pinching plates on the two sliding blocks in opposite directions to move the two sliding blocks towards each other, separating the limiting insertion hole from the limiting insertion rod. Then, rotate the rotating clamping block to open it, thus removing the clamping effect on the wire without the need for tools. This improves the convenience and efficiency of separating the clamping device from the wire.

[0015] This invention, through the cooperation of the movable clamping block and the screw, allows the wire to be clamped and fixed by simply rotating one of the corresponding screws when the clamping force of the movable clamping block is insufficient. This is achieved by moving the screw downwards with the corresponding movable clamping block under the action of the thread. Furthermore, since it is not necessary to rotate both screws at the same time, unnecessary trouble is avoided in the wire clamping and positioning work, thus improving the practicality of this clamping device.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1: Please refer to Figures 1 to 4 :

[0031] This utility model proposes a relay protection clamping device, comprising: a mounting base plate 1, with mounting holes 101 on both the left and right sides of the upper end face of the mounting base plate 1; a fixed clamping block 2 is fixedly connected to the middle of the upper end face of the mounting base plate 1, and a rotating connecting block 102 is fixedly connected to the left side of the upper end face of the mounting base plate 1, with a rotating clamping block 3 rotatably connected to the upper end of the rotating connecting block 102 via a rotating shaft; a quick-limiting component 4 is provided between the right end of the rotating clamping block 3 and the right side of the upper end face of the mounting base plate 1; a rectangular sliding groove 301 is uniformly formed on the bottom end face of the rotating clamping block 3, and a movable clamping block 5 is slidably connected within the rectangular sliding groove 301; the quick-limiting component 4 includes a support block 401 and a fixed block 404, the support block 401 is fixedly connected to the right end of the rotating clamping block 3, and two sliding grooves 402 are formed on the right end face of the support block 401, each sliding groove 402... 2. Each component is internally equipped with a spring guide rod 407, and each spring guide rod 407 is externally fitted with a spring. Each sliding groove 402 is slidably connected to a sliding block 403 through the spring guide rod 407. The lower ends of the opposing surfaces of the two sliding blocks 403 are provided with limit insertion holes 406. There are two fixing blocks 404, and the upper surfaces of the opposing surfaces of the two fixing blocks 404 are fixedly connected with limit insertion rods 405. By rotating the clamping block 3 in cooperation with the quick limiting component 4, the pinching plates on the two sliding blocks 403 can be manually pinched in opposite directions, causing the two sliding blocks 403 to move towards each other, so that the limit insertion holes 406 and the limit insertion rods 405 are separated. Then, the clamping block 3 can be rotated open, so that the wire loses its clamping and fixing function, thereby improving the convenience and operational efficiency of this clamping device when separating from the wire.

[0032] The upper surface of the rotating clamp 3 is uniformly provided with threaded through holes 303 that communicate with the rectangular slide groove 301. Each rectangular slide groove 301 has strip-shaped slide grooves 302 on both the left and right sides inside, which are used to slide and connect with the guide slide bar 502.

[0033] The bottom surface of the support block 401 has two strip-shaped openings 408, and the two strip-shaped openings 408 are respectively connected to two sliding grooves 402, so as to facilitate the passage of the two sliding blocks 403.

[0034] Each sliding block 403 has a pinch plate fixedly connected to its right end face, and both pinch plates have anti-slip stripes on their opposite sides, which makes the opposite sides of the two pinch plates have better friction and improves the convenience of pinching.

[0035] When the quick-stop component 4 is in the stop state, the stop rod 405 is inserted into the stop hole 406, and the rotating clamp 3 is in the closed state at this time, so that the rotating clamp 3 in the closed state can be quickly stopped, which improves the operating efficiency of this clamping device when clamping and stopping.

[0036] Example 2, based on Example 1, such as Figure 1 and Figure 3 As shown, a screw 501 is rotatably connected to the middle of the upper end face of the movable clamping block 5, and the screw 501 is threadedly connected to the threaded through hole 303. A rotating handwheel is provided at the upper end of the screw 501. Guide slides 502 are provided on both the left and right sides of the movable clamping block 5, and the guide slides 502 are slidably connected to the strip-shaped slide groove 302. Arc-shaped clamping openings are provided on the clamping surfaces of both the fixed clamping block 2 and the movable clamping block 5, and rubber anti-slip pads 6 are provided inside the arc-shaped clamping openings. Through the cooperation of the movable clamping block 5 and the screw 501, when the clamping force of the movable clamping block 5 is insufficient, only one screw 501 needs to be rotated to make the screw 501 move downward with the corresponding movable clamping block 5 under the action of the thread, so as to achieve the clamping and fixing effect of the wire. It is not necessary to rotate both screws 501 at the same time, avoiding unnecessary trouble for the wire clamping and positioning work.

[0037] The working principle of this embodiment is as follows: When clamping the wire on the relay protection device, firstly, the pinching plates on the two sliding blocks 403 are manually pinched in opposite directions, causing the two sliding blocks 403 to move towards each other, thus separating the limiting socket 406 from the limiting rod 405. Then, the rotating clamp 3 is rotated open, and the wire on the relay protection device is placed into the clamping opening on the fixed clamp 2. Next, the rotating clamp 3 is rotated closed. During this process, the pinching plates on the two sliding blocks 403 must be manually pinched in opposite directions, causing the two sliding blocks 403 to move towards each other. When the rotating clamp 3 is closed, the pinch plate is released. At this time, the two sliding blocks 403 move simultaneously in opposite directions under the spring force of the spring guide rod 407, so that the limiting insertion hole 406 and the limiting insertion rod 405 are inserted, quickly limiting the rotating clamp 3. At this time, the wire will be clamped and fixed in the arc-shaped clamp between the fixed clamp 2 and the movable clamp 5. If the clamping force of the movable clamp 5 is insufficient, it is only necessary to rotate the corresponding screw 501, so that the screw 501 can move the corresponding movable clamp 5 downward under the action of the thread, thereby achieving the clamping and fixing effect on the wire.

[0038] When the relay protection device is no longer in use and it is necessary to separate the clamping device from the conductor, simply pinch the pinching plates on the two sliding blocks 403 in opposite directions by hand. This will move the two sliding blocks 403 towards each other, causing the limiting socket 406 to separate from the limiting rod 405. Then, rotate the rotating clamp 3 to open it, thereby removing the clamping and fixing effect on the conductor. This improves the convenience and efficiency of separating the device from the conductor.
