Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, and in particular to a tension-resistant clamp for electric power engineering. Background Art

[0002] As an indispensable key hardware in the power system, the original design of the tension clamp is to firmly fix the conductor and ensure that the conductor can be safely and reliably hung on the tension string group or tower under huge tension, especially at corners, joints and terminal connections. This function is crucial to maintaining the stable operation of the power grid, because it not only ensures the smooth transmission of electric energy, but also effectively resists the influence of natural environment such as wind, prevents the conductor from deflecting, and thus ensures the safety and efficiency of the power line.

[0003] There are many types of tension clamps, among which the wedge-type tension clamp is a commonly used tension clamp. Its working principle is to use the splitting force of the wedge to lock the conductor (ground wire) in the clamp. After the conductor is stressed, the wedge and the conductor slide along the wall of the clamp barrel toward the clamp outlet at the same time, becoming tighter and tighter and gradually locked. This wedge-type tension clamp is easy to install and remove, and is usually used to install steel strands, tighten ground wires, and guy wires of guyed towers; however, in terms of structure, after the wedge-shaped block enters the clamp body, it is easy to fall out when receiving external force, and the stability is poor, especially when it is impacted, such as under natural conditions such as strong winds and hail, the locking is easy to fail.

[0004] At the same time, the tension clamps are exposed to the outdoors for a long time and will inevitably be eroded by wind, sun and rain. Such harsh environmental conditions can easily lead to loose connections, which in turn causes poor contact. Once the poor contact situation worsens, it will not only affect the normal transmission of electric energy, but may also cause serious accidents such as burning of the clamps due to overheating, posing a huge threat to the stable operation of the power system. Such accidents not only increase the complexity and difficulty of subsequent operation and maintenance work, but also bring additional safety risks and workload to maintenance personnel, requiring them to have higher professional skills and coping capabilities.

[0005] Although tension clamps play a vital role in the power system, their weather resistance and maintenance issues cannot be ignored. It is necessary to detect their status through technological innovation so that they can be repaired in time when the outgoing line is abnormal, and continuously improve their performance and reliability to ensure the safe, stable and efficient operation of the power grid. Based on this, it is necessary to study a tension clamp for power engineering. Summary of the invention

[0006] In view of this, an object of the present invention is to provide a tension-resistant clamp for electric power engineering, which effectively solves the problems of poor structural stability and lack of locking detection of the existing wedge-shaped tension-resistant clamp.

A pawl that cooperates with the ratchet wheel and limits the position is rotatably arranged in the wedge block, and a spring sheet is arranged on the outside of the pawl, and the rotating shaft of the pawl extends to the front side of the wedge block, so that the pawl can be operated from the outside to release the self-locking of the ratchet wheel.

[0008] Furthermore, both sides of the clamping body are in an arc-shaped structure, fins are arranged around the clamping body, and a wedge-shaped opening is opened on the front side.

[0009] Furthermore, a fixing seat is arranged at the bottom of the wedge-shaped inner cavity, a guide groove is arranged in the middle of the fixing seat, and the racks are fixedly arranged on both sides of the fixing seat.

[0010] Furthermore, avoidance grooves are provided on both sides of the wedge-shaped block, and the central guide block is formed between the avoidance grooves.

[0011] Furthermore, assembly grooves are opened on both sides of the avoidance groove, and a fixing groove is opened on the outer side of the assembly groove. The rack and the ratchet are fixedly set on the rotating shaft. The bottom of the rotating shaft is rotatably set on the bottom of the assembly groove, and the other end is rotatably set on the fixing plate, and the fixing plate is fixedly installed in the fixing groove.

[0012] Furthermore, the fixing plate includes a fixing portion and a connecting portion, wherein the fixing portion is rotatably connected to the rotating shaft and exposes the gear; and the connecting portion is fixedly connected to the fixing groove and is integrated with the fixing portion.

[0013] Furthermore, it also includes a detection mechanism, which includes a detection wheel, a spring, a slider and an angular displacement sensor; corresponding detection grooves are arranged above and below the inside of the outer wire groove, a limit slide is arranged in the detection groove, the slider is adapted to be mounted in the limit slide, the spring is arranged at the bottom of the slider and the limit slide, so that the slider can elastically translate relative to the limit slide; the surface of the detection wheel is adapted to the inside of the outer wire groove, the detection wheel is arranged in the slider via a rotating shaft, the angular displacement sensor is fixed on the slider and is connected to the rotating shaft of the detection wheel; under the action of the spring, the detection wheel is in the outer wire groove and can fit with the surface of the wire.

[0015] Furthermore, the surface of the detection wheel is provided with anti-slip grooves.

[0016] Furthermore, the angular displacement sensor is connected to the controller via a wireless module, and the controller obtains angular displacement information of the angular displacement sensor and compares it with a standard threshold value, thereby generating an alarm signal.

[0017] The beneficial effects of the above technical solution are as follows: the present invention mainly optimizes and improves the wedge-shaped tension-resistant clamp structure, especially the wedge-shaped wire clamp for double-wire clamping of double-sided wire troughs. The structure has a sufficient range in the middle area, providing a reliable basis for the improvement of the equipment; the specific improvement of the present invention mainly involves two aspects, namely the locking reinforcement aspect and the detection feedback aspect. The anti-retreat function of the wedge block is realized through the locking mechanism, and the locking progress can automatically provide the wedge block with anti-retreat assistance to prevent it from loosening. It will not separate even in the face of impact. When dismantling, the anti-loosening locking structure can be achieved through simple operation, and then dismantling can be carried out. The detection mechanism realizes the slippage detection of the wire. When the wire slides relative to the clamping body, the controller is reported for early warning processing. Even if the intervention is abnormal, major safety accidents can be avoided.

[0018] In the specific implementation structure, the locking mechanism converts translation into rotation by configuring a gear and a rack structure, and drives the ratchet to rotate by rotation. The ratchet is constrained by the pawl to rotate in only one direction, thereby achieving the purpose of stopping retreat. That is, as the gear can only rotate in one direction, and due to the engagement of the gear and the rack, the wedge block can be constrained to move only in one direction in the clamp body. By operating the pawl to disengage the ratchet, the gear can be rotated freely, which is convenient for disassembly. As a result, the wedge block and the clamp body have good stability, and even when subjected to external force impact, they still have good stability.

[0019] As for the detection mechanism, the present invention configures a detection wheel in the outer wire slot. After locking is completed, the detection wheel is tightly attached to the surface of the wire. When the wire slips, it will drive the detection wheel to rotate, and its rotation state is obtained through the angular displacement sensor and reported to the controller, which performs early warning processing.

[0020] The present invention has a novel structure, and the overall improvement fully considers the safety and stability factors. The self-locking function of the locking mechanism, the real-time monitoring function of the detection mechanism and the optimized design of the clamp structure together constitute a safe and reliable tension-resistant clamp system, which reduces safety accidents caused by loose or falling wires and improves the overall operating stability of the power project.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a tension-resistant clamp for electric power engineering, especially a wedge-shaped tension-resistant clamp for double wire slots, which uses the splitting force of the wedge to lock the wire in the wire clamp during operation. After the wire is subjected to force, the wedge and the wire slide along the wall of the wire clamp barrel toward the outlet of the wire clamp at the same time, becoming tighter and tighter until they are gradually locked. However, in terms of structure, after the wedge-shaped block enters the clamp body, it is easy to fall out when receiving external force, and the stability is poor. Especially when it is impacted, such as under natural conditions such as strong winds and hail, the locking is easy to fail. Based on this, in view of the problem of poor structural stability of the existing wedge-shaped tension-resistant clamp, this embodiment provides a tension-resistant clamp for electric power engineering.

[0024] like Figure 1-4 As shown in , a tension-resistant clamp for power engineering includes a clamp body 1, a wedge block 2 and a hanger 3. In this embodiment, the frame body has a wedge-shaped inner cavity, and both sides of the wedge-shaped inner cavity 6 are provided with inner wire grooves 7. The wedge block 2 is adapted to be nested in the clamp body 1. The two sides of the clamp body 1 are in an arc-shaped structure, and fins 4 are provided around the clamp body 1. The front side is provided with an opening in the same shape as the wedge. The hanger 3 is provided on both sides of the clamp body 1. This embodiment also includes a locking mechanism, and the wedge block 2 is locked in the inserted state through the built-in locking mechanism. The two sides of the clamp body 1 are in an arc-shaped structure, and fins are provided, which not only enhances the structural strength of the clamp body 1, but also improves the heat dissipation performance. The opening adapted to the wedge block 2 opened on the front side of the clamp body 1 allows the wedge block 2 to be smoothly embedded and fixed.

[0025] In the specific implementation structure, the locking mechanism includes a rack 8, a gear 12, a ratchet 13, a pawl 16 and a spring 17; the interior of the clamp body 1 is provided with a wedge-shaped inner cavity 6, the front side of the wedge-shaped inner cavity is open, and an inner wire groove 7 is provided on the inner side; racks 8 are provided on both sides of the center of the wedge-shaped inner cavity 6, and a guide groove 8 is formed between the racks 8, and the setting direction of the guide groove 8 and the rack 8 is parallel to the center line of the wedge-shaped inner cavity; in this embodiment, the inner wire groove is an arc-shaped structure, the center of the guide groove 8 is on the center line of the wedge-shaped inner cavity, and the two sides of the guide groove 8 are racks 8 with toothed structures facing outward.

[0026] In the specific arrangement structure, a fixed seat is arranged at the bottom of the wedge-shaped inner cavity 6, a guide groove 8 is arranged in the middle of the fixed seat, and the rack 8 is fixedly arranged on both sides of the fixed seat. The guide groove 8 is a square structure. Figure 5-6 As shown in the figure, the guide groove 8 and the rack 8 structure are located in the upper area of ​​the wedge-shaped inner cavity 6. In this structure, the wedge block 2 has no clamping effect at the initial stage of insertion. As the wedge block 2 goes deeper, the wire groove gradually fits on the wire. Therefore, the locking structure is arranged in the upper area to provide a stop force in the clamping stage.

[0027] like Figure 7-8 As shown in the figure, outer wire grooves are provided on both sides of the wedge block 2; the inner wire groove and the outer wire groove are combined into a clamping wire groove 5; a center guide block 10 is provided along the center of the bottom of the wedge block 2, and the center guide block 10 is adapted to be mounted in the guide groove 8 and can slide along the guide groove 8; in the specific structure, the center guide block 10 is a continuous long strip structure, and the center of the center guide block 10 is located on the center line of the wedge block 2, which can be adapted to be inserted into the guide groove 8 and translate along the guide groove 8, thereby constraining the translation state of the wedge block 2, so that it translates along the configuration direction of the guide groove 8, that is, the central axis of the clamp body 1, ensuring the meshing relationship between the gear 12 and the rack 8, and playing the role of guiding and positioning constraint.

[0028] In order to configure the meshing relationship between the rack 8 and the gear 12, in this embodiment, avoidance grooves 11 corresponding to the rack 8 and used to avoid the rack 8 are provided on both sides of the center guide block 10; the avoidance groove 11 is a square groove structure in the shape of a long strip, and a gear 12 capable of meshing with the rack 8 is provided on the outside of the avoidance groove 11, and avoidance grooves 11 are provided on both sides of the wedge block 2, and a center guide block 10 is formed between the avoidance grooves 11, or during implementation, a larger avoidance groove 11 is formed first, and a center guide block 10 structure is fixed in the middle of the avoidance groove 11.

[0029] The central guide block 10 and the guide groove 8 are designed along the center of the bottom of the wedge block 2, so that the wedge block 2 can slide flexibly along the guide groove 8, which is convenient for adjusting the size of the clamping wire groove to adapt to wires or optical cables of different diameters. At the same time, the rotating shaft 15 of the ratchet 16 extends to the front of the wedge block 2, which is convenient for operation from the outside to release the self-locking of the ratchet 13, making the installation and removal process more convenient.

[0030] The rotating shaft 14 of the gear 12 is fixedly connected to the ratchet 13, and a pawl 16 that cooperates with the ratchet 13 to limit the position is rotatably arranged in the wedge block 2. A spring piece 1717 is arranged on the outer side of the pawl 16, and the rotating shaft of the pawl 16 extends to the front side of the wedge block 2, so that the pawl 16 can be operated from the outside to release the self-locking of the ratchet 13. In this embodiment, the rotating shaft of the pawl 16 extends outward and can be operated from the outside to disengage the pawl 16 from the ratchet 13, and then the ratchet 13 and the gear 12 can be rotated freely, that is, the gear 12 and the rack 8 are freely slidably connected, so that the wedge block 2 can be knocked outward to disengage it from the clamp body 1. On the contrary, if the pawl 16 is always in cooperation with the ratchet 13, the gear 12 can only perform a directional rotation, that is, the wedge block 2 can only be pushed inward and cannot be pulled outward, providing a stop function for the wedge block 2.

[0031] In a specific connection structure, the fixing plate 18 includes a fixing portion 181 and a connecting portion 182. The fixing portion 181 is rotationally connected to the rotating shaft 14 and exposes the gear 12. The connecting portion is fixedly connected to the fixing groove and is integrated with the fixing portion.

[0032] When in use, the present embodiment first makes the central guide block 10 of the wedge block 2 correspond to the guide groove 8. Due to the guiding effect of the two, the wedge block 2 can only be pushed inward along the center, so that the distance between the inner wire groove and the outer wire groove is gradually reduced, the wire is placed between the inner wire groove and the outer wire groove in a timely manner, and the insertion length of the wire groove is adjusted, and then the wedge block 2 is pushed inward to further reduce the clamping gap. When the clamping gap is small enough, there is friction between the inner wire groove, the outer wire groove and the wire. By pulling the wire, the wedge block 2 can continue to translate inward, and the gear 12 rotates under the action of the rack 8. The gear 12 is coaxial with the ratchet 13. At the same time, the ratchet 13 is locked with the pawl 16. When the wire cannot be pulled, the locking is completed. When it needs to be dismantled, the present embodiment screws the rotating shaft of the ratchet 16 on the surface to disengage the ratchet 16 from the ratchet 13, and then the wedge block 2 is knocked in the opposite direction to achieve the dismantling operation.

[0033] This embodiment achieves a secure locking of the wedge block 2 by introducing a locking mechanism, including a rack 8, a gear 12, a ratchet 13, a pawl 16 and a spring 1717. The cooperation between the ratchet 13 and the pawl 16 provides a self-locking function, ensuring that the wedge block 2 will not accidentally loosen when subjected to an external force, thereby enhancing the reliability and safety of the entire tension-resistant clamp; Embodiment 2: Based on Embodiment 1, this embodiment further optimizes the structure of the wedge-shaped tension clamp. This embodiment mainly addresses the problem of lack of clamping state feedback in the prior art and failure to provide timely feedback when the conductor slides. Based on the above problem, this embodiment also includes a detection mechanism, thereby providing a wedge-shaped tension clamp capable of detection.

[0034] The detection mechanism includes a detection wheel 19, a spring 23, a slider 21 and an angular displacement sensor 24; corresponding detection grooves are arranged on the upper and lower parts of the outer wire groove, and a limit slide 22 is arranged in the detection groove. The slider 21 is adapted to be mounted in the limit slide 22. In specific implementation, the limit slide is a dovetail groove structure, which can be limited from the top and bottom and only allows the slider 21 to translate along the limit slide. The slider 21 is a dovetail block and is adapted to be mounted in the limit slide.

[0035] The spring 23 is arranged at the bottom of the slider 21 and the limiting slideway, so that the slider 21 can be elastically translated relative to the limiting slideway; through the spring 23 structure, the slider 21 is always outward, that is, the detection wheel 19 is outwardly located in the clamping gap, so that the detection wheel 19 is tightly attached to the surface of the wire, and anti-slip grooves are arranged on the surface of the detection wheel 19 to ensure its fitting effect, so that when the wire becomes loose, that is, when the wire translates relative to the wedge block 2, the detection wheel 19 is driven to rotate.

[0036] The surface of the detection wheel 19 is adapted to the interior of the outer wire groove. The detection wheel 19 is set in the slider 21 through a rotating shaft. The angular displacement sensor 24 is fixed on the slider 21 and is connected to the rotating shaft of the detection wheel 19. Under the action of the spring 23, the detection wheel 19 is in the outer wire groove and can fit with the surface of the wire. The angular displacement sensor 24 is connected to the controller via a wireless module. The controller obtains the angular displacement information of the angular displacement sensor 24 and compares it with the standard threshold value, thereby generating an alarm signal.

[0037] This embodiment can monitor the state of the wire in the clamping wire trough in real time. Through the fit between the detection wheel 19 and the surface of the wire, and the monitoring of the rotation of the detection wheel 19 by the angular displacement sensor 24, the looseness or deviation of the wire can be detected in time, and the information is transmitted to the controller for processing through the wireless module, thereby improving the intelligence level of the tension clamp and providing convenience for the operation and maintenance of the power project.

[0038] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to utilize the self-locking function of the locking mechanism, the real-time monitoring function of the detection mechanism and the optimized design of the clamp structure to jointly form a safe and reliable tension-resistant clamp system, reduce safety accidents caused by loose or falling wires, and improve the overall operational stability of power engineering. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
