Description

Technical Field

[0001] This invention relates to the field of tension-driven overhead wire equipment, and in particular to an overhead insulated conductor capable of detecting tension. Background Technology

[0002] Currently, during the construction of overhead insulated conductors, sufficient safety distances need to be maintained, which increases the overhead length of the conductors. In application, the tension generated on the overhead line acts directly on the connection ends of the conductors. If the accurate value of the tension cannot be effectively understood, it is difficult to coordinate well with the overhead line construction process.

[0003] In existing technologies, such as the intelligent monitoring device and method for tension of overhead transmission lines disclosed in CN102288223B, the traction force is directly measured on the traction rope of the transmission line through a traction force measuring device. This means that if the tension is too high, although the measuring device can monitor the situation, it cannot provide emergency protection measures, which can lead to structural damage to the transmission line due to the traction force. Therefore, the current devices for detecting overhead transmission lines still have certain defects in use. Summary of the Invention

[0004] The purpose of this invention is to provide an overhead insulated conductor capable of detecting tension, thereby solving the problems existing in the prior art, improving the tension detection effect of overhead insulated conductors, and providing timely protection for the conductor structure when excessive tension occurs.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides an overhead insulated conductor capable of detecting tension, comprising: The box body has a tension sensor fixedly attached to its inner wall; A first connecting rod is connected to the housing, and a wire is wound around the first connecting rod. One end of the wire is fixedly connected to the detection end of the tension sensor. The second connecting rod is connected to the box body, and the box body is provided with an elastic component. The elastic end of the elastic component is connected to the second connecting rod so that the second connecting rod can be elastically slidably connected to the box body. As the second connecting rod moves gradually away from its initial position, the elastic potential energy of the second connecting rod gradually increases. A buffer plate is snapped onto the side wall of the second connecting rod. A control component is provided on the second connecting rod. The control component is communicatively connected to the tension sensor. The control component enables the protruding end of the buffer plate to move. The other end of the circuit away from the tension sensor is wound around the second connecting rod, and the buffer plate abuts against the circuit.

[0006] Preferably, a buffer block is further provided between the first connecting rod and the second connecting rod, and a pressure support assembly is provided inside the box. The working end of the pressure support assembly is connected to the buffer block, and the buffer block abuts against the line to bend the line.

[0007] Preferably, the control component includes: A movable ring is slidably connected inside the second connecting rod. A servo cylinder is fixedly connected to the inner top of the second connecting rod. The piston rod of the servo cylinder is fixedly connected to the movable ring. A groove is formed on the side wall of the second connecting rod. A buffer plate is embedded in the groove. The top end of the buffer plate is fixedly connected to the movable ring, and the bottom end of the buffer plate abuts against the groove.

[0008] Preferably, the inner bottom surface of the groove is provided with a sliding groove, a slider is slidably connected in the sliding groove, the slider is fixedly connected to the bottom end of the buffer sheet, and the bottom surface of the slider and the sliding groove are respectively fixedly connected to the two ends of the first spring.

[0009] Preferably, the two ends of the second connecting rod are respectively connected to limit blocks, the box body is fixedly connected to a limit seat, the limit seat is provided with a limit groove, the limit block slides in the limit groove, and leaf springs are respectively fixed to the opposite sides of the limit groove. The leaf springs are arc-shaped, and the protruding ends of the leaf springs abut against the limit blocks.

[0010] Preferably, the pressure support assembly includes: A base is fixedly connected to the box body. A slot is provided on the side of the base near the buffer block. A locking block is slidably connected in the slot. One end of the locking block is fixedly connected to the buffer block, and the two ends of a second spring are fixedly connected between the locking block and the inner wall of the slot. A pressure sensor is disposed in the empty slot, and the detection end of the pressure sensor is connected to the card block.

[0011] Preferably, a control box is fixedly connected to the outer wall of the box body, and the control box is communicatively connected to the tension sensor and the servo cylinder respectively.

[0012] Preferably, the two ends of the first connecting rod are respectively rotatably connected to a fixing block, and the fixing block is fixedly connected to the inner wall of the box.

[0013] Preferably, the buffer sheet has an arc-shaped structure, and several buffer sheets are arranged at equal intervals around the second connecting rod in the circumferential direction.

[0014] Preferably, the circuit is spirally wound around the first connecting rod and the second connecting rod, and the portion of the circuit located between the first connecting rod and the second connecting rod is distributed in a horizontal direction.

[0015] The present invention discloses the following technical effects: This invention fixes the circuit to a tension sensor and then winds it around a first connecting rod and a second connecting rod. The first connecting rod rotates and is fixed to the housing, while the second connecting rod slides elastically within the housing. This allows the circuit to be elastically relieved when subjected to traction force through the second connecting rod. As the second connecting rod moves, its elasticity increases, reaching maximum elasticity to fix the circuit relative to the second connecting rod. This effectively transmits the tension to the tension sensor, which detects the circuit tension. When the tension exceeds the circuit load, a control component can be used to control a buffer plate. By stretching the buffer plate, its protruding end retracts, reducing the diameter of the second connecting rod, thus effectively relieving the tension on the circuit. This provides effective circuit protection measures in addition to tension detection, preventing damage caused by excessive tension. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-5 The present invention provides an overhead insulated conductor capable of detecting tension, comprising: Box 1, with tension sensor 2 fixedly connected to the inner wall; first connecting rod 3, which is connected to the box 1, with wire 4 wound around the first connecting rod 3, one end of wire 4 being fixedly connected to the detection end of tension sensor 2; second connecting rod 5, which is connected to the box 1, and the box 1 is provided with an elastic component, the elastic end of the elastic component being connected to the second connecting rod 5, so that the second connecting rod 5 can be elastically slidably connected to the box 1. As the second connecting rod 5 moves gradually away from its initial position, the elastic potential energy of the second connecting rod 5 gradually increases. The buffer plate 6 is snapped onto the side wall of the second connecting rod 5. A control component is provided on the second connecting rod 5. The control component is communicatively connected to the tension sensor 2. The control component can move the protruding end of the buffer plate 6. The other end of the line 4 away from the tension sensor 2 is wound around the second connecting rod 5. The buffer plate 6 abuts against the line 4.

[0021] This invention fixes the circuit 4 to the tension sensor 2, and then winds it around the first connecting rod 3 and the second connecting rod 5. The first connecting rod 3 rotates and is fixed to the housing 1, while the second connecting rod 5 is elastically slidable inside the housing 1. When the circuit 4 is subjected to traction force, it can be elastically relieved by the second connecting rod 5. As the second connecting rod 5 moves, its elasticity increases, and at the point of maximum elasticity, the circuit 4 and the second connecting rod 5 are relatively fixed. This effectively transmits the tension to the tension sensor 2. The tension sensor 2 detects the tension of the circuit 4. When the tension value exceeds the load of the circuit 4, the buffer plate 6 can be controlled by the control component. By stretching the buffer plate 6, the protruding end of the buffer plate 6 retracts, reducing the diameter of the second connecting rod 5, thereby effectively relieving the tension on the circuit 4. Thus, based on the tension detection of the circuit 4, it can effectively provide protective measures for the circuit 4 to prevent damage caused by excessive tension.

[0022] Furthermore, a buffer block 7 is provided between the first connecting rod 3 and the second connecting rod 5. A pressure support assembly is provided inside the box 1. The working end of the pressure support assembly is connected to the buffer block 7. The buffer block 7 abuts against the line 4 to bend the line 4.

[0023] Similarly, the pressure support component, together with the buffer block 7, supports the line 4, causing the line 4 to bend. When the tension is too high, the line 4 squeezes the buffer block 7, providing a buffer for the deformation of the line 4 and reducing the impact of tension on the line 4.

[0024] Furthermore, the control components include: The movable ring 8 is slidably connected inside the second connecting rod 5. The inner top of the second connecting rod 5 is fixedly connected to the servo cylinder 9. The piston rod of the servo cylinder 9 is fixedly connected to the movable ring 8. The side wall of the second connecting rod 5 is provided with a groove. The buffer plate 6 is embedded in the groove. The top end of the buffer plate 6 is fixedly connected to the movable ring 8, and the bottom end of the buffer plate 6 abuts against the groove.

[0025] The servo cylinder 9 drives the moving ring 8 to rise and fall, and the moving ring 8 is fixed to the top of the buffer plate 6. As the moving ring 8 moves, one end of the buffer plate 6 is squeezed and raised and lowered, so that the protruding end in the middle of the buffer plate 6 can extend or retract, thereby adjusting the winding support force on the line 4 and protecting the structure of the line 4.

[0026] Furthermore, a sliding groove is provided on the inner bottom surface of the groove, and a slider 10 is slidably connected in the sliding groove. The slider 10 is fixedly connected to the bottom end of the buffer plate 6, and the two ends of the first spring 11 are respectively fixedly connected between the bottom surface of the slider 10 and the sliding groove.

[0027] By using the slider 10 and the first spring 11 to provide elastic support at the bottom of the buffer plate 6, when the line 4 experiences tension fluctuations within the normal range during use, the line 4 squeezes the buffer plate 6, and the buffer plate 6 can squeeze the slider 10 and the first spring 11 to release the floating tension.

[0028] Understandably, when performing tension detection on line 4 alone, the buffer plate 6 can be pressed down by the servo cylinder 9, causing the middle part of the buffer plate 6 to bulge out and press the slider 10 and the first spring 11, effectively transmitting the tension to the first connecting rod 3 and the tension sensor 2.

[0029] Furthermore, the two ends of the second connecting rod 5 are respectively connected to limit blocks 12, and the box body 1 is fixedly connected to a limit seat 13. A limit groove is opened in the limit seat 13, and the limit block 12 slides in the limit groove. A leaf spring 14 is fixedly connected to the opposite side of the limit groove. The leaf spring 14 has an arc-shaped structure, and the protruding end of the leaf spring 14 abuts against the limit block 12.

[0030] The limiting block 12 and the limiting seat 13 limit both ends of the second connecting rod 5, so that the second connecting rod 5 is rotatably connected in the box 1. The leaf spring 14 elastically abuts against the limiting seat 13. When the line 4 is subjected to tension, the leaf spring 14 is squeezed to buffer the tension.

[0031] Furthermore, the pressure support assembly includes: a base 15, fixedly connected inside the housing 1, with a slot on the side of the base 15 near the buffer block 7, a locking block 16 slidingly connected in the slot, one end of the locking block 16 being fixedly connected to the buffer block 7, and the two ends of a second spring 17 being fixedly connected between the locking block 16 and the inner wall of the slot; and a pressure sensor 18, disposed in the slot, with the detection end of the pressure sensor 18 connected to the locking block 16.

[0032] The pressure sensor 18 detects the moving pressure of the locking block 16. When the buffer block 7 abuts against the line 4, the second spring 17 provides elastic support for the locking block 16. When the tension on the line 4 exceeds the elastic force of the second spring 17, the line 4 straightens and presses the buffer block 7 into the slot. By detecting the pressure of the locking block 16 through the pressure sensor 18, it is possible to obtain whether the second spring 17 has reached the compression limit pressure range, thus ensuring the accuracy of tension detection of the line 4.

[0033] Furthermore, a control box 19 is fixedly connected to the outer wall of the box 1, and the control box 19 is communicatively connected to the tension sensor 2 and the servo cylinder 9 respectively.

[0034] Specifically, the control box 19 adopts a common communication structure of central processing unit and signal transceiver, which is a conventional technical means and will not be described in detail.

[0035] Furthermore, the two ends of the first connecting rod 3 are respectively rotatably connected to fixing blocks 20, and the fixing blocks 20 are fixedly connected to the inner wall surface of the box body 1.

[0036] The first connecting rod 3 is used to guide the line 4, so that the line 4 is distributed at an angle inside the box 1, which makes it easier for the buffer block 7 to abut against one side of the line 4, causing the line 4 to bend. The first connecting rod 3 is connected to the fixed block 20, so that the tension on the line 4 can be accurately transmitted to the tension sensor 2 through the first connecting rod 3.

[0037] Furthermore, the buffer plate 6 has an arc-shaped structure, and several buffer plates 6 are arranged at equal intervals around the second connecting rod 5 in a circumferential direction.

[0038] Furthermore, the line 4 is spirally wound around the first connecting rod 3 and the second connecting rod 5, and the portion of the line 4 located between the first connecting rod 3 and the second connecting rod 5 is distributed in the horizontal direction.

[0039] Ensure the stability of the contact between buffer block 7 and line 4.

[0040] This invention provides a working principle for an overhead insulated conductor capable of detecting tension: One end of the line 4 is fixed to the tension sensor 2, and the other end is wound around the first connecting rod 3 and the second connecting rod 5 in sequence. Then, it extends out of the box 1 to be strung. When subjected to tension, the line 4 presses the buffer plate 6. After exceeding the elastic extreme value of the first spring 11 and the leaf spring 14, the tension is transmitted to the buffer block 7, which compresses the second spring 17 to its extreme value. At this time, the tension of the line 4 wound on the first connecting rod 3 is the same as that of the line 4 outside the box 1. Thus, the tension of the line 4 can be detected by the tension sensor 2. If it is necessary to protect the structure of the line 4, the servo cylinder 9 is lifted upward to retract the protruding structure of the buffer plate 6 and reduce the structural diameter of the second connecting rod 5, which can alleviate the effect of the tension on the line 4 and enhance the protection effect.

[0042] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
