Description
Technical Field
[0001] The utility model relates to the technical field of transmission lines, in particular to a device for preventing heat generation of a drainage plate for transmission lines. Background Technique
[0002] The transmission line is realized by boosting the electric energy generated by the generator with a transformer and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line poles, conductors, insulators, line fittings, guy wires, pole foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmitted current, the transmission is divided into AC transmission and DC transmission. The basic process of power transmission is to create conditions for the electromagnetic energy to be transmitted along the direction of the transmission line. The transmission capacity of the line is governed by various laws of electromagnetic fields and circuits. Taking the earth potential as the reference point (zero potential), the line conductors need to be under the high voltage applied by the power source, which is called the transmission voltage.
[0003] At present, the drainage plates on the market are metal fittings made of conductive materials and adopt special design structures, mainly used for the static protection and grounding devices of transmission lines. In actual use, very high voltages and currents often occur during the power transmission process. The drainage plate can effectively reduce the influence of voltage and current and achieve the functions of static protection and grounding. In ultra-high voltage transmission lines, the drainage plates of strain clamps will have heat generation or even burning phenomena. Among them, during the operation of the drainage plates of strain clamps, the conductors vibrate under the action of wind, causing the bolts of the equipment clamps to loosen, resulting in insufficient torque of the bolts of the installed strain clamps and the contact surfaces of the connecting parts not being tight, leading to an increase in the contact resistance of the equipment clamps and heat generation, and subsequent heat generation or even burning of the drainage plates. Content of the Utility Model
[0004] The purpose of the utility model is to provide a device for preventing heat generation of a drainage plate for transmission lines to solve the problems raised in the above background technique.

[0008] Furthermore, a fixed rod is fixedly connected to the outer wall of the fixed plate. The outer wall of the fixed rod is slidably connected to the positioning rod. The addition of the fixed rod restricts the movement track of the positioning rod.
[0009] Furthermore, a second sliding groove is formed inside the first sliding groove. A second sliding block is slidably connected inside the second sliding groove and the outer wall of the second sliding block is fixedly connected to the first sliding block. The addition of the second sliding groove prevents the subsequent first sliding block from moving out of the first sliding groove.
[0010] Furthermore, a threaded rod body is rotatably connected to the side of the outer wall of the extrusion block away from the first sliding groove. One end of the threaded rod body penetrates the outer wall of the second drainage plate and the threaded rod body is threadedly connected to the second drainage plate. The addition of the connecting plate enables the first sliding block to drive the positioning rod to move.
[0011] Furthermore, an installation groove is formed at one end of the strain clamp. An installation threaded rod is threadedly connected inside the installation groove. A connection head is fixedly connected to one end of the installation threaded rod. The addition of the extrusion block enables the threaded rod to drive the first sliding block to move.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. The anti - heating device for drainage plates used in transmission lines of the present utility model can prevent the contact surface between the outer walls of the first drainage plate and the second drainage plate from loosening.

In the present utility model, during the power transmission process, high voltage and current are often generated. The drainage plate can effectively reduce the influence of voltage and current, achieving the functions of static protection and grounding. This device can perform secondary position limit fixation on the drainage plate, reducing the probability of the bolts of the device clamp loosening due to the vibration of the wire under the action of wind during the operation of the drainage plate of the subsequent strain clamp, thereby reducing the phenomenon of subsequent drainage plate heating or even burning out.

[0023] A heat prevention device for a drainage plate used in a transmission line includes a strain clamp 1. A first drainage plate 2 is fixedly connected to the outer wall of the strain clamp 1. A second drainage plate 3 is provided on one side of the outer wall of the first drainage plate 2. A groove 4 is formed inside the second drainage plate 3. A connection hole 5 is formed on the outer wall of the second drainage plate 3. An extrusion block 6 is provided inside the groove 4. A first chute 7 is formed on the outer wall of the extrusion block 6. A first slider 8 is slidably connected inside the first chute 7. A connecting plate 9 is hinged to the outer wall of the first slider 8. A positioning rod 10 is fixedly connected to one end of the connecting plate 9 away from the first slider 8. One end of the positioning rod 10 penetrates inside the connection hole 5 and the positioning rod 10 is slidably connected to the second drainage plate 3. A connection sleeve 11 is fixedly connected to the outer wall of the first drainage plate 2, and the connection sleeve 11 is slidably connected to the connection hole 5.
[0024] In a preferred embodiment, a positioning groove 12 is formed on the outer wall of the connection sleeve 11 and one end of the positioning rod 10 is slidably connected to the positioning groove 12. A fixing plate 13 is fixedly connected inside the groove 4. When the positioning rod 10 moves, the positioning rod 10 will move inside the connection hole 5, and at the same time, the positioning rod 10 will move inside the groove 4.
[0025] In a preferred embodiment, a fixing rod 14 is fixedly connected to the outer wall of the fixing plate 13, and the outer wall of the fixing rod 14 is slidably connected to the positioning rod 10. When the positioning rod 10 moves, the positioning rod 10 will simultaneously slide on the outer wall of the fixing rod 14, so as to limit the movement track of the subsequent positioning rod 10.
[0026] In a preferred embodiment, a second chute 15 is formed inside the first chute 7. A second slider 16 is slidably connected inside the second chute 15 and the outer wall of the second slider 16 is fixedly connected to the first slider 8.

[0027] Working principle of the present utility model: When using this drainage plate, rotate the screw rod body 17 so that the screw rod body 17 moves relative to the second drainage plate 3 through threads. At the same time, the screw rod body 17 can slide inside the groove 4, causing the screw rod body 17 to drive the extrusion block 6 to move, so that the extrusion block 6 slides inside the groove 4. The extrusion block 6 simultaneously drives the first sliding groove 7 and the second sliding groove 15 to move, enabling the extrusion block 6 to drive the first sliding block 8 and the second sliding block 16 through the first sliding groove 7 and the second sliding groove 15. The first sliding block 8 will slide inside the first sliding groove 7, and the second sliding block 16 simultaneously slides inside the second sliding groove 15, causing the extrusion block 6 to drive the connecting plate 9 through the first sliding groove 7, the second sliding groove 15, the first sliding block 8 and the second sliding block 16, so that the connecting plate 9 slides inside the groove 4.

There is a shape memory alloy gasket between the first drainage plate 2 and the second drainage plate 3. At the same time, both the first drainage plate 2 and the second drainage plate 3 are internally filled with nano-intelligent materials, thereby facilitating the fixation of the positions of the first drainage plate 2 and the second drainage plate 3.

One end of the screw rod body 17 penetrates through the outer wall of the second drainage plate 3 and the screw rod body 17 is threadedly connected to the second drainage plate 3. When the first sliding block 8 moves, the first sliding block 8 will drive the connecting plate 9 to move, so that the connecting plate 9 drives the positioning rod 10 to move inside the groove 4.
[0029] In a preferred embodiment, an installation groove 18 is provided at one end of the strain clamp 1. An installation screw rod 19 is threadedly connected inside the installation groove 18. One end of the installation screw rod 19 is fixedly connected to a connection head 20. When the screw rod body 17 moves, the screw rod body 17 moves inside the groove 4, and at the same time, the screw rod body 17 can drive the extrusion block 6 to move.
[0030] Working principle of the utility model: When the connector 20 needs to be replaced, rotate the connector 20 at this time, so that the connector 20 drives the installation threaded rod 19 to move, and the installation threaded rod 19 rotates and moves inside the installation groove 18. At the same time, the installation threaded rod 19 and the installation groove 18 move through the thread, so that the installation threaded rod 19 can slowly move out of the installation groove 18 through the thread with the installation groove 18, and the new connector 20 drives one end of the installation threaded rod 19 into the installation groove 18, so that the subsequent connector 20 can be conveniently replaced adaptively.
