Description

Technical Field

[0001] This utility model relates to the field of power line clamp technology, specifically to a multi-position adjustable one-code windproof fastening device. Background Technology

[0002] Insulators, as key components in overhead lines, play a dual role in power transmission systems. On one hand, they must possess excellent electrical insulation properties to withstand high voltages during line operation, preventing current leakage to towers or other grounding components and avoiding electric shock accidents and power loss. The main function of wire clamps is to securely fix the high-voltage line to the top of the insulator. Existing common power clamps are formed directly during the clamping process; that is, when two clamps hold the top of the insulator, two opposing wire clamps on top also hold the high-voltage line, and then they are fixed with bolts. However, because this type of power clamp requires the simultaneous installation of both clamp halves during use, it is time-consuming, labor-intensive, and inefficient. To address this problem, a power line clamp for insulator connection has been proposed (Chinese patent document publication number CN211183307U). It includes a left clamp body and a right clamp body hinged together at the top and positioned opposite each other. Both the left and right clamp bodies have an integrally formed upper clamping section, a lower clamping section, and an end connecting section connecting the lower part of the upper clamping section and the side of the lower clamping section. The upper clamping section has outwardly protruding arc-shaped clamping arms. The arc-shaped clamping arms of the left and right clamp bodies are positioned opposite each other, creating a space between the two arc-shaped clamping arms to clamp the cable. The lower clamping section has outwardly protruding arc-shaped clamping arms. The arc-shaped clamping arms of the left and right clamp bodies are positioned opposite each other, creating a space between the two arc-shaped clamping arms to clamp the top of the insulator. A bolt passes between the end connecting sections of the left and right clamp bodies. This clamp can quickly fix cables and insulators, and has the advantages of simple structure, convenient assembly, and improved labor efficiency.

[0003] The aforementioned clamps hold insulators via left and right clamping bodies, but the fixed-size clamping cavity has several shortcomings. Insulators in power systems come in a variety of specifications; insulators of different voltage levels and types vary significantly in size and shape. A fixed-size clamping cavity is difficult to adapt, limiting its application scenarios and increasing selection costs. In complex installation and maintenance scenarios, it cannot flexibly address insulator replacement needs, affecting emergency repair progress. Furthermore, size mismatches can lead to insulator swaying and wear, loosening of connections, or even subjecting the insulator to additional stress, causing damage and threatening line safety. Simultaneously, companies need to purchase multiple models of clamps, increasing procurement and inventory management costs and resulting in resource waste. Utility Model Content

[0039] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0040] As shown in the figure: A multi-position adjustable one-code windproof fastening device includes a clamp assembly and a pressure cap assembly.

[0041] The clamp assembly includes a first clamp 1, a second clamp 2, and a linkage head. Both the first clamp 1 and the second clamp 2 have an arc-shaped structure, which allows for a better fit to the shape of the insulator and achieves stable clamping. One end of both the first clamp 1 and the second clamp 2 is hinged to the linkage head.

[0042] The free end of the first clamp 1 is provided with a fastening piece 3, and the free end of the second clamp 2 is provided with a fastener 4.

[0043] The first clamp 1 and the second clamp 2 can rotate around the hinge axis. When the free ends of the first clamp 1 and the second clamp 2 are connected, an annular closed clamping cavity is formed, which can clamp the insulator.

[0044] The cap assembly includes a cap body 5 and a pressure plate 6. The cap body 5 consists of a cap base plate 501, a first side wing 502, and a second side wing 503. The first side wing 502 and the second side wing 503 are disposed opposite each other on the side of the cap base plate 501, and together with the cap base plate 501, they form a stable structural frame. The first side wing 502 is hinged to the linkage head, and the hinge axis of the first side wing 502 is perpendicular to the hinge axes of the first clamp 1 and the second clamp 2. The second side wing 503 has a fastening groove 7 along its end. The pressure plate 6 is disposed in the middle of the inner side surface of the cap base plate 501. The pressure plate 6 is fixed to the cap base plate 501 by bolts. To ensure the flatness and stability of the bolt installation, the cap base plate 501 is provided with corresponding countersunk holes. The end face of the pressure plate 6 away from the pressure cover substrate 501 is provided with an arc-shaped pressure groove. The length direction of the pressure groove is parallel to the hinge axis of the first clamp 1 and the second clamp 2. The arc-shaped pressure groove allows the pressure plate 6 to better fit the shape of the wire when pressing the wire, increasing the contact area and improving the stability of the pressure, while also effectively avoiding damage to the wire.

[0045] The fastening plate 3 is disposed on the outer arc wall of the free end of the first clamp 1, and multiple limiting grooves 8 are formed on the outer edge of the fastening plate 3. The multiple limiting grooves 8 are evenly distributed along their length direction, and each limiting groove 8 represents a gear position.

[0046] Fastener 4 includes a locking screw 401 and a locking head 402 screwed onto the locking screw 401. The locking head 402 includes a locking nut and a knob sleeved on the locking nut, allowing for manual rotation by the operator to tighten and loosen the screw. One end of the locking screw 401 is hinged to the outer arc wall of the free end of the second clamp 2. Specifically, the outer arc wall of the free end of the second clamp 2 is provided with a hinge seat, and a hinge shaft is provided on the hinge seat. One end of the locking screw 401 is connected to a hinge ring, which is sleeved on the hinge shaft. Fastener 4 can lock the first clamp 1, the second clamp 2, and the second side wing 503 together.

[0047] The specific locking method is as follows: Connect the free ends of the first clamp 1 and the second clamp 2 and put them on the top of the insulator to be installed. Select the appropriate limiting groove 8 according to the actual size of the insulator. At the same time, press the cover assembly down and turn the locking screw 401 so that the locking screw 401 is inserted into the limiting groove 8 and the fastening groove 7 of the second side wing 503. Then rotate the locking head 402. As the locking head 402 moves down, it squeezes the second side wing 503 and the fastening plate 3 to complete the locking between the three.

[0048] A retaining edge 9 is provided at the outer end of the second side wing 503. After locking, the retaining edge 9 can prevent the locking screw 401 from rotating, thus preventing it from coming out of the limiting groove 8 and the fastening groove 7 and causing locking failure.

[0049] The first clamp 1, the second clamp 2, and the pressure cap assembly are all made of polytetrafluoroethylene (PTFE). The inner arc walls of the first clamp 1 and the second clamp 2 are provided with anti-slip textures. PTFE has excellent corrosion resistance, weather resistance, and self-lubricating properties, enabling long-term stable use in harsh outdoor environments, reducing maintenance costs. Its self-lubricating properties also facilitate relative movement between components. Furthermore, to reduce the overall weight of the device and improve installation and transportation convenience, several weight-reducing holes are provided on the first clamp 1, the second clamp 2, and the pressure cap assembly. These weight-reducing holes effectively reduce the weight of the device without affecting its structural strength. The anti-slip textures on the inner arc walls of the first clamp 1 and the second clamp 2 increase the friction between the clamp and the insulator, further improving clamping stability, preventing the insulator from sliding within the clamp, and ensuring the insulator's fixed position during power transmission.

[0050] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
