Description

Technical Field

[0001] This utility model belongs to the field of high-voltage line technology, and in particular relates to a high-voltage line and insulator fixing buckle that can be installed while energized. Background Technology

[0002] High-voltage lines refer to cables or wires used to transmit electricity. They are usually installed on transmission towers or poles and are isolated from other supporting structures by insulators. Insulators are electrical devices used to support power lines and prevent current from flowing to the ground through the supporting structure. They are usually made of ceramic, glass or composite materials and have good electrical insulation performance and mechanical strength.

[0003] In practical use, the connection between high-voltage lines and insulators is a very important link. After long-term use, natural disasters such as wind, earthquakes, and lightning strikes may cause high-voltage lines to vibrate or swing violently, which may cause the connection between the line and the insulator to loosen, resulting in poor connection or detachment, and further causing power system failures.

[0004] In the existing technology, when loosening and detachment occur between high-voltage lines and insulators, there is a lack of technology that can be installed efficiently and safely while the power is on. The installation process requires shutting down the power system, resulting in a long power outage time and an inability to restore power quickly. This not only incurs high power outage losses but also greatly reduces maintenance and installation efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems mentioned in the background art by providing a high-voltage line and insulator fixing clip that enables live installation of high-voltage lines and insulators without requiring the power system to be shut down.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-voltage line and insulator fixing clip that can be installed energized, comprising:

[0008] The fastener body has an internal mounting cavity and a slot on one side. The side wall of the fastener body away from the slot has a first extension and two second extensions. The first extension is located at the center of the fastener body, and the two second extensions are symmetrically distributed on both sides of the first extension. The upper ends of the first extension and the second extension are fixedly connected to a sleeve, and a rotating shaft is fixedly installed inside the sleeve.

[0009] A locking mechanism is used to fix a high-voltage line in a slot. The locking mechanism includes a first rotating shaft fixedly connected to the inner walls of the upper and lower sides of the slot. A locking plate is rotatably sleeved on the first rotating shaft. A second rotating shaft is also fixedly connected to the inner walls of the upper and lower sides of the slot. A locking plate is rotatably sleeved on the second rotating shaft. A return spring is provided between the locking plate and the inner wall of the slot. The upper and lower ends of the locking plate near the locking plate protrude outwards, and the protruding positions of the upper and lower ends of the locking plate bend towards the middle position of the locking plate.

[0010] The lower mounting mechanism supports the insulator from below.

[0011] The upper mounting mechanism works in conjunction with the lower mounting mechanism to secure the insulators.

[0012] Preferably, the lower mounting mechanism includes an I-shaped pad rotatably sleeved on a rotating shaft, a first rubber block fixedly connected to the upper end of the I-shaped pad, two symmetrically distributed extension blocks fixedly connected to the upper end of the fixing buckle body, a first through groove opened on the extension block, a first locking piece provided in the first through groove, the first locking piece bending towards the center of the fixing buckle body, and two side plates fixedly connected to the side of the I-shaped pad away from the rotating shaft.

[0013] Preferably, when the I-shaped pad is pressed to the bottom, the first locking piece engages with the upper end of the I-shaped pad.

[0014] Preferably, the upper mounting mechanism includes a U-shaped cover plate rotatably sleeved on a rotating shaft, a second rubber block fixedly connected to the lower end of the U-shaped cover plate, a second through groove provided on each side plate, a second locking piece provided in the second through groove, the second locking piece being bent toward the rotating shaft, and a slot provided on the outer wall of the U-shaped cover plate, the slot cooperating with the second locking piece at the corresponding position.

[0015] Preferably, when the U-shaped cover is pressed to fit the two side plates, the second locking piece engages inside the slot.

[0016] Preferably, a semi-circular mounting groove is provided on the side wall of the first rubber block and the second rubber block that are close to each other.

[0017] Preferably, both the first rubber block and the second rubber block are provided with an adhesive mechanism for fixing the insulator between the first rubber block and the second rubber block with adhesive after installation. The adhesive mechanism includes a liquid storage cavity opened inside the first rubber block and the second rubber block, the liquid storage cavity being filled with adhesive. A drain groove is opened on the side wall of the first rubber block and the second rubber block that are close to each other, and the drain groove is connected to the liquid storage cavity and the outside.

[0018] Preferably, the drain tank is equipped with an automatic pressure relief valve for automatically draining the adhesive liquid in the storage chamber after installation.

[0019] Compared with existing technologies, the advantages of this live-line and insulator fixing clip are:

[0020] 1. This utility model utilizes a combination of a locking mechanism, a lower mounting mechanism, and an upper mounting mechanism. When high-voltage lines and insulators become loose or fall off, workers insert the high-voltage line into the slot using insulating grippers. The grippers then push the locking plate, which is then locked in place by a locking plate, securing the fixing buckle to the high-voltage line. Next, an I-shaped pad is pressed down, and a first locking piece locks the pad in place. Finally, a U-shaped cover is pressed down, and a second locking piece locks the cover in place. This allows for live installation of high-voltage lines and insulators without shutting down the power system, avoiding losses caused by power outages and improving installation efficiency.

[0021] 2. By setting up an adhesive bonding mechanism, after installation, the insulator is placed in the semi-circular mounting groove of the first rubber block and the second rubber block. The adhesive in the storage chamber will be squeezed to exceed the critical value of the automatic pressure relief valve, thereby automatically discharging the adhesive in the storage chamber and automatically bonding and fixing the insulator. No manual operation is required, saving workload and avoiding safety accidents. Attached Figure Description

[0035] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0036] Example: Refer to Figures 1 to 6 A high-voltage line and insulator fixing clip that can be installed energized, comprising:

[0037] The fastener body 1 has an installation cavity 11 inside. A slot 12 is provided on one side of the fastener body 1. A first extension 13 and two second extensions 14 are provided on the side wall of the fastener body 1 away from the slot 12. The first extension 13 is located at the center of the fastener body 1. The two second extensions 14 are symmetrically distributed on both sides of the first extension 13. A sleeve 15 is fixedly connected to the upper end of both the first extension 13 and the second extension 14. A rotating shaft 16 is fixedly installed inside the sleeve 15.

[0038] The locking mechanism 2 is used to fix the high-voltage line in the slot 12. The locking mechanism 2 includes a first rotating shaft 21 fixedly connected to the inner walls of the upper and lower sides of the slot 12. A locking plate 22 is rotatably sleeved on the first rotating shaft 21. A second rotating shaft 23 is also fixedly connected to the inner walls of the upper and lower sides of the slot 12. A locking plate 24 is rotatably sleeved on the second rotating shaft 23. A return spring 25 is provided between the locking plate 24 and the inner wall of the slot 12. The upper and lower ends of the locking plate 22 near the locking plate 24 protrude outwards. The protruding positions of the upper and lower ends of the locking plate 22 are bent towards the middle position of the locking plate 22.

[0039] Specifically, the locking plate 22, which protrudes outward and bends towards the middle of the locking plate 22, allows the locking plate 24 to lock precisely at the protruding position of the locking plate 22 when it is reset by the elastic force of the return spring 25, thereby fixing the locking plate 22 through the locking plate 24.

[0040] Specifically, anti-slip teeth are added to the side of the locking plate 22 that is in contact with the clamping plate 24 to increase the friction between the locking plate 22 and the locking plate 24 and reduce the possibility of the circuit sliding under external force. At the same time, a locking groove matching the protruding part of the locking plate 22 is provided on the locking plate 24. When the locking plate 24 is locked under the action of the return spring 25, the groove and the protruding part of the locking plate 22 are tightly matched, further improving the reliability of the fixation.

[0041] The lower mounting mechanism 3 supports the insulator from below. The lower mounting mechanism 3 includes an I-shaped pad 31 rotatably sleeved on the rotating shaft 16. A first rubber block 32 is fixedly connected to the upper end of the I-shaped pad 31. Two symmetrically distributed extension blocks 33 are fixedly connected to the upper end of the fixing buckle body 1. A first through groove 34 is provided on the extension block 33. A first locking piece 35 is provided in the first through groove 34. The first locking piece 35 is bent toward the center of the fixing buckle body 1. Two side plates 36 are fixedly connected to the side of the I-shaped pad 31 away from the rotating shaft 16.

[0042] Specifically, when the I-shaped pad 31 is pressed to the bottom, the first locking piece 35 engages with the upper end of the I-shaped pad 31.

[0043] The upper mounting mechanism 4 works in conjunction with the lower mounting mechanism 3 to fix the insulator. The upper mounting mechanism 4 includes a U-shaped cover plate 41 that is rotatably sleeved on the rotating shaft 16. A second rubber block 42 is fixedly connected to the lower end of the U-shaped cover plate 41. A second through groove 43 is provided on each side plate 36. A second locking piece 44 is provided in the second through groove 43. The second locking piece 44 is bent toward the rotating shaft 16. A slot 45 is provided on the outer wall of the U-shaped cover plate 41. The slot 45 cooperates with the second locking piece 44 at the corresponding position.

[0044] Specifically, when the U-shaped cover plate 41 is pressed to fit the two side plates 36, the second locking piece 44 engages inside the slot 45.

[0045] Specifically, both the first locking plate 35 and the second locking plate 44 are made of spring steel, which can bend when compressed and return to their original position when no longer compressed, so that the first locking plate 35 can lock the I-shaped pad 31 and the second locking plate 44 can lock the U-shaped cover plate 41.

[0046] To address the problem in existing technologies that lack efficient and safe installation techniques for high-voltage lines and insulators when they become loose or detached, and which require shutting down the power system during installation, this invention utilizes the coordinated use of a locking mechanism 2, a lower installation mechanism 3, and an upper installation mechanism 4. When the high-voltage line and insulator become loose or detached, workers can adjust the position of the fixing buckle body 1 using insulating claws, aligning the slot 12 of the fixing buckle body 1 with the high-voltage line, allowing the high-voltage line to be inserted into the slot 12. Then, the insulating claws push the locking plate 22 closer to the locking plate 24, and push the locking plate 24 away from the high-voltage line. When the locking plate 22 is in close contact with the high-voltage line, the locking plate 24, under the elastic force of the return spring 25, moves closer to the locking plate 22, locking and fixing the locking plate 22, thus securing the fixing buckle body 1 to the high-voltage line. Further installation is then carried out using insulating claws. The clamping claws press down on the I-shaped pad 31. During the downward swinging motion of the I-shaped pad 31 around the rotating shaft 16, the first locking piece 35 in the first through groove 34 is squeezed and deformed. After the I-shaped pad 31 is pressed down to the bottom and fits against the top of the high-voltage line, the first locking piece 35 returns to its original position and abuts against the upper end of the I-shaped pad 31, locking the I-shaped pad 31. Finally, the insulating claws press down on the U-shaped cover plate 41. During the downward swing of the center of the circle, the second locking piece 44 in the second through groove 43 is squeezed and deformed. After the U-shaped cover plate 41 is pressed to fit against the I-shaped pad 31, the second locking piece 44 returns to its original position and abuts against the slot 45, thus realizing the installation between the I-shaped pad 31 and the U-shaped cover plate 41. This enables the live installation of high-voltage lines and insulators without shutting down the power system, avoiding losses caused by power outages and improving installation efficiency.

[0047] Semi-circular mounting grooves 5 are provided on the side walls of the first rubber block 32 and the second rubber block 42 that are close to each other.

[0048] Both the first rubber block 32 and the second rubber block 42 are provided with an adhesive mechanism 6, which is used to fix the insulator between the first rubber block 32 and the second rubber block 42 with adhesive after installation. The adhesive mechanism 6 includes a liquid storage cavity 61 opened inside the first rubber block 32 and the second rubber block 42, which is filled with adhesive. Both the first rubber block 32 and the second rubber block 42 are provided with a drain groove 62 on the side wall that is close to each other, and the drain groove 62 connects the liquid storage cavity 61 to the outside.

[0049] Specifically, the drain tank 62 is equipped with an automatic pressure relief valve, which is used to automatically discharge the adhesive in the storage chamber 61 after installation. The automatic pressure relief valve can automatically open when the adhesive in the storage chamber 61 is squeezed and the hydraulic pressure exceeds the threshold value of the automatic pressure relief valve, so as to discharge the adhesive in the storage chamber 61.

[0050] Specifically, the adhesive in the liquid storage chamber 61 is made of polyurethane adhesive, which has moisture curing properties and can cure after contact with moisture in the air. It is often used in sealing or caulking scenarios. It also has excellent adhesion, water resistance, wear resistance and elasticity, and has a good effect on the installation and fixing of insulators.

[0051] Specifically, an auxiliary squeezing element is provided on the fixing buckle body 1. After installation, the operator can operate the element through the insulated gripper to apply pressure to the first rubber block 32 and the second rubber block 42, so as to cause the adhesive in the liquid storage chamber 61 to be discharged.

[0052] Specifically, the automatic pressure relief valve adopts a diaphragm structure, mainly composed of a valve body, diaphragm, spring, and adjusting bolt. The diaphragm isolates the liquid storage chamber 61 from the outside. When the pressure of the adhesive in the liquid storage chamber 61 acts on the diaphragm, and the pressure exceeds the spring force set, the diaphragm deforms, causing the drain hole on the valve body to open, and the adhesive is discharged through the drain groove. The spring force can be finely adjusted by the adjusting bolt. Depending on the viscosity of the adhesive and the actual installation requirements, when the adhesive is a common medium-viscosity polyurethane adhesive, the opening pressure is set to 0.2 MPa to ensure that the adhesive can be discharged smoothly when the insulator is installed in place and subjected to normal compression, without premature leakage due to insufficient pressure.

[0053] It is worth mentioning that, by setting up the gluing mechanism 6, after installation, the insulator is placed in the semi-circular mounting groove 5 of the first rubber block 32 and the second rubber block 42. At the same time, the compression of the insulator against the first rubber block 32 and the second rubber block 42, as well as the compression between the first rubber block 32 and the second rubber block 42, can compress the adhesive in the liquid storage chamber 61. After installation, the adhesive in the liquid storage chamber 61 will be compressed to exceed the critical value of the automatic pressure relief valve, so that the adhesive in the liquid storage chamber 61 can be automatically discharged from the drain trough 62 and flow to the contact position between the first rubber block 32, the second rubber block 42 and the insulator, automatically achieving the gluing and fixing of the insulator. No manual operation by the staff is required, saving workload and avoiding the occurrence of safety accidents.

[0054] The functional principle of this utility model can be explained through the following operation methods:

[0055] When the high-voltage line and insulator become loose or fall off, the slot 12 of the fixing buckle body 1 is aligned with the high-voltage line by the insulating claw, so that the high-voltage line can be inserted into the slot 12.

[0056] The locking plate 22 is pushed by the insulating claws, so that the locking plate 22 is close to the locking plate 24. When the locking plate 22 is in close contact with the high voltage line, the locking plate 24 locks and fixes the locking plate 22, so that the fixing buckle body 1 is fixed on the high voltage line.

[0057] Press the I-shaped pad 31 to make it swing and press down around the rotating shaft 16, squeezing and deforming the first locking piece 35 in the first through groove 34. After the I-shaped pad 31 is pressed to the bottom and fits against the top of the high voltage line, the first locking piece 35 returns to its original position and abuts against the upper end of the I-shaped pad 31, locking the I-shaped pad 31.

[0058] Pressing the U-shaped cover plate 41, during the process of the U-shaped cover plate 41 swinging and pressing down with the rotating shaft 16 as the center, the second locking piece 44 in the second through groove 43 is squeezed and deformed. After the U-shaped cover plate 41 is pressed to fit against the I-shaped pad 31, the second locking piece 44 returns to its original position and abuts against the slot 45, thus realizing the installation between the I-shaped pad 31 and the U-shaped cover plate 41.

[0059] During installation, the insulator is placed between the first rubber block 32 and the second rubber block 42. The compression of the insulator against the first rubber block 32 and the second rubber block 42, as well as the compression between the first rubber block 32 and the second rubber block 42, can compress the adhesive in the liquid storage chamber 61. Through the automatic pressure relief valve, the adhesive in the liquid storage chamber 61 can be automatically discharged from the drain trough 62 and flow to the contact position between the first rubber block 32, the second rubber block 42 and the insulator.
