Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and particularly to an insulator assembly. Background Art

[0002] An insulator assembly is a component used in a power system to support and fix live conductors and insulate them from the grounding body or other live conductors. The insulating part is the core of the insulator assembly and is usually made of ceramic, glass or composite materials. Metal accessories generally include steel feet, iron caps, flanges, etc., which are used to connect the insulating part and electrical equipment or transmission lines, playing the role of transmitting mechanical force and electrical connection. They are usually made of high-strength metal materials to ensure the mechanical stability and electrical reliability of the insulator assembly during operation.

[0003] Chinese Patent with Application No. CN202411269418.2 discloses a combined insulator for electricity use, including an insulator body. The insulator body is composed of a connecting rod and a plurality of insulating parts, and the plurality of insulating parts are sleeved on the outer wall of the connecting rod at equal intervals. The connecting rod is made of metal, the insulating parts are made of ceramic, the shape of the insulating parts is umbrella-shaped, one end of the connecting rod is connected with a mounting seat through bolts, and a plurality of mounting holes are formed in the outer wall of the mounting seat. The other end of the connecting rod is connected with a support frame through bolts, and a constraint mechanism is arranged inside the support frame. Although the present invention can reduce vibration to a certain extent and restrain the cable in the constraint mechanism, after the wind continuously acts on the cable, and when the insulator encounters extremely cold weather, the internal materials of the insulator produce large stress changes due to thermal expansion and contraction. If the anti-freezing performance of its material is not good, small cracks are likely to occur inside. When the wind continuously impacts the insulator through the cable and there is no buffering and vibration reduction for the impact force, it is easy for the internal structure of the insulator to expand the cracks continuously over time and under the continuous action of stress, and finally the insulator breaks, reducing the service life of the insulator.

[0004] Therefore, an insulator assembly is invented to solve the above problems. Summary of the Invention

One end of the connecting rod is fixedly connected with a support frame, and a constraint mechanism is slidably arranged inside the support frame for restraining the cable. The insulator assembly further includes:

[0007] The anti - detachment mechanism is arranged between the support frame and the restraint mechanism and is used to restrain the cable within the restraint mechanism;

[0008] The buffer mechanism is arranged on the support frame. The buffer mechanism includes a placement groove opened on the support frame, and a guiding block is slidably connected within the placement groove. When the restraint mechanism slides horizontally, the restraint mechanism can drive the guiding block to slide along the axial direction of the connecting rod;

[0009] The shock - absorbing mechanism is arranged between the support frame and the connecting rod. The shock - absorbing mechanism includes a sleeve movably connected to the connecting rod, and an adjusting rod is movably connected within the sleeve. One end of the adjusting rod away from the sleeve is fixedly connected to the guiding block.

When the pushing block slides, it can drive the guiding rod to slide.

[0012] Preferably, the shock - absorbing mechanism further includes a shock - absorbing groove opened within the connecting rod. Both the sleeve and the adjusting rod are located within the shock - absorbing groove. A guiding groove is opened on the circumferential side of the sleeve, and an auxiliary rod is fixedly connected to the inner wall of the shock - absorbing groove. The free end of the auxiliary rod is inserted into the guiding groove. When the sleeve slides, under the action of the auxiliary rod and the guiding groove, the sleeve rotates along the shock - absorbing groove.

[0013] Preferably, a first elastic member is arranged between the shock - absorbing groove and the sleeve, and a second elastic member is arranged between the sleeve and the adjusting rod. The elastic force of the first elastic member is greater than that of the second elastic member.

[0014] Preferably, sliding grooves are opened on both sides inside the support frame, sliders are slidably connected within the sliding grooves, and the sliders are fixedly connected to the corresponding pushing blocks.

[0015] Preferably, a third elastic member is arranged between the anti - detachment plate and the wire clamp.

[0019] The technical effects and advantages of the present invention:

[0020] 1. Through the arrangement of the guiding block, the anti-disengagement plate, the ejector rod, the connecting rod and the pushing block, when the wind force on the cable is too small, the clip can be kept in a stable position under the action of the friction force between the guiding block, the pushing block and the support frame, reducing the problem that the clip slides with a very small force, and also reducing the vibration force transmitted to the insulating member through the support frame and the connecting rod, which is convenient for improving the service life of the insulating member. At the same time, when the wind force is too large, the lateral impact force can be decomposed by the guiding block, the connecting rod and the pushing block, reducing the impact force acting on the insulating member through the support frame and the connecting rod, and enabling one of the anti-disengagement plates to quickly seal the opening of the clip, avoiding the problem that the cable falls off from the clip when the cable drives the clip to slide, improving the stability of the cable in the clip, and reducing the vibration force received by the insulating member, thereby improving the service life of the insulating member.

[0021] 2. Through the arrangement of the sleeve, the adjusting rod, the first elastic member, the second elastic member, the guiding groove and the auxiliary rod, not only can the impact force received by the clip be decomposed into a downward force to overcome the elastic force of the second elastic member for primary vibration damping, but also the force exceeding the threshold value of the second elastic member can be decomposed again through the sleeve, and the sleeve rotates to reduce the impact force. At this time, it can be avoided that the impact force directly acts on the insulating member through the support frame and the connecting rod. Through the multi-stage vibration damping and decomposition of the impact force, the insulating member is effectively prevented from being affected by the impact force for a long time, avoiding the internal fragmentation of the insulating member in bad weather, and at the same time, the service life of the insulating member can be effectively improved.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment 1

[0036] In the prior art, generally, the cable is directly buffered by a spring - connected wire clamp. However, when the spring is compressed to the limit distance, the impact force finally directly acts on the insulator. At the same time, when the cable sways under the action of wind, it is also easy to move inside the wire clamp, and finally it is easy for the cable to fall off from the wire clamp, which is not conducive to the stable transmission of electric power by the cable. Therefore, this embodiment is invented to solve the above problems.

[0037] AsFigures 1 to 7 , this embodiment provides an insulator assembly, including an insulator body 1. The insulator body 1 is composed of a connecting rod 101 and a plurality of insulating members 102. One end of the connecting rod 101 is fixedly connected to a support frame 2. A constraint mechanism 3 is slidably arranged in the support frame 2 for constraining a cable. The constraint mechanism 3 includes a guide rail 301 fixedly connected to the support frame 2. A connecting block 302 is slidably connected in the guide rail 301. One end of the connecting block 302 away from the connecting rod 101 is fixedly connected to a wire clamp 303. One end of the connecting block 302 close to the connecting rod 101 is fixedly connected to a push rod 304. The free end of the push rod 304 contacts the end face of the guide block 502.

[0038] An anti - detachment mechanism 4 is arranged between the support frame 2 and the constraint mechanism 3 for constraining the cable within the constraint mechanism 3. The anti - detachment mechanism 4 includes two connecting rods 401 hinged to the guide block 502. The free ends of the connecting rods 401 are hinged to a push block 402. The push block 402 is slidably connected to the support frame 2. Anti - detachment plates 403 are slidably connected to both ends of the wire clamp 303. One end of the anti - detachment plate 403 away from the wire clamp 303 is fixedly connected to a guiding rod 404. The free end of the guiding rod 404 contacts the corresponding push block 402. When the push block 402 slides, it can drive the guiding rod 404 to slide. Sliding grooves 405 are formed on both sides inside the support frame 2. Sliding blocks 406 are slidably connected in the sliding grooves 405. The sliding blocks 406 are fixedly connected to the corresponding push blocks 402. A third elastic member 407 is arranged between the anti - detachment plate 403 and the wire clamp 303.

[0039] A buffer mechanism 5 is arranged on the support frame 2. The buffer mechanism 5 includes a placement groove 501 formed on the support frame 2. A guide block 502 is slidably connected in the placement groove 501. When the constraint mechanism 3 slides horizontally, the constraint mechanism 3 can drive the guide block 502 to slide along the axial direction of the connecting rod 101. The upper end face of the guide block 502 is composed of an inclined surface 5021 and a vertical surface 5022. Two groups of inclined surfaces 5021 and vertical surfaces 5022 are mirror - symmetrically arranged, and the two inclined surfaces 5021 are connected.

[0040] A plurality of insulating members 102 are evenly sleeved on the connecting rod 101. A plurality of insulating members 102 are all umbrella - shaped. The other end of the connecting rod 101 is fixedly connected to a fixing rod 103. The axial cross - section of the fixing rod 103 is an inverted T - shape. A limiting nut 104 is threadedly connected to one end of the connecting rod 101 close to the fixing rod 103.

[0041] During actual use, first fix the connecting rod 101 to the conductor cross arm through the fixing rod 103 and the limit nut 104. Then place the cable on the wire clamp 303. When the cable is subjected to the acting force of the wind, the acting force generated by the swinging of the cable is applied to the wire clamp 303. When the wind force is too small, under the action of the friction force between the guiding block 502 and the placement groove 501, the two inclined surfaces 5021 on the guiding block 502 can prevent the ejector rod 304 from moving horizontally. As a result, the ejector rod 304 drives the wire clamp 303 through the connecting block 302 to maintain a stable position, avoiding the problem that the wire clamp 303 can move when the wind force is too small, and reducing the situation where the swinging force acts on the insulating part 102 through the support frame 2 and the connecting rod 101, which is convenient for improving the service life of the insulating part 102.

[0042] When the wind force is large, the wind force drives the wire clamp 303 to shake through the cable, causing the wire clamp 303 to drive the connecting block 302 to slide along the guide rail 301. The connecting block 302 drives the ejector rod 304 to move, causing the ejector rod 304 to push the guiding block 502 to slide along the placement groove 501 in the direction of the connecting rod 101 through the inclined surface 5021 on the guiding block 502. And the vertical surface 5022 on the guiding block 502 limits the moving range of the ejector rod 304. The downward sliding of the guiding block 502 drives the connecting rod 401 to slide downward, reducing the lateral impact force. At the same time, the connecting rod 401 drives the pushing block 402 to slide downward, and the pushing block 402 drives the sliding block 406 to slide downward along the sliding groove 405. Since the end face of the pushing block 402 close to the wire clamp 303 is an inclined surface, and the thickness of the upper end of the pushing block 402 is greater than that of its lower end, and the wire clamp 303 slides in the direction of one of the pushing blocks 402, at this time, the pushing block 402 can quickly push a guiding rod 404 to slide in the direction of the wire clamp 303. The guiding rod 404 quickly drives a retaining plate 403 to slide into the wire clamp 303, and the third elastic member 407 is compressed. Since the wire clamp 303 drives the other guiding rod 404 to gradually move away from the pushing block 402, the speed of the other retaining plate 403 sliding into the wire clamp 303 is slow. At this time, the retaining plate 403 that quickly slides into the wire clamp 303 can block the opening of the wire clamp 303, avoiding the cable falling off from the inside of the wire clamp 303 during the swinging process of the cable driving the wire clamp 303, and providing the stability of the cable inside the wire clamp 303.

[0043] In summary, through the settings of the guiding block 502, the anti-disengagement plate 403, the ejector rod 304, the connecting rod 401, and the pushing block 402, not only can the cable clamp 303 be ensured to be in a stable position under the action of the friction force between the guiding block 502, the pushing block 402, and the support frame 2 when the cable is subjected to too small wind force, reducing the problem that the cable clamp 303 slides under a very small force, but also the vibration force transmitted to the insulating part 102 through the support frame 2 and the connecting rod 101 is reduced, facilitating the improvement of the service life of the insulating part 102. At the same time, when the wind force is too large, the lateral impact force can be decomposed through the guiding block 502, the connecting rod 401, and the pushing block 402, reducing the impact force acting on the insulating part 102 through the support frame 2 and the connecting rod 101, and enabling one of the anti-disengagement plates 403 to quickly seal the opening of the cable clamp 303, avoiding the problem that the cable falls off from the cable clamp 303 when the cable drives the cable clamp 303 to slide, improving the stability of the cable in the cable clamp 303, reducing the vibration force received by the insulating part 102, and improving the service life of the insulating part 102.

[0044] Embodiment 2

[0045] During use, it is found that when the insulator encounters extremely cold weather, the internal material of the insulator generates large stress changes due to thermal expansion and contraction. If the anti-freezing performance of its material is not good, micro-cracks are likely to occur inside. And when the wind force is too large, after the cable clamp 303 slides to the maximum stroke, the impact force directly acts on the support frame 2, and the impact force is transmitted to the connecting rod 101 through the support frame 2 and then acts on the insulating part 102. At this time, the insulating part 102 is continuously affected by the impact force for a long time. At this time, it is easy for the internal structure of the insulating part 102 to continuously expand the cracks over time and under the continuous action of stress, ultimately leading to the rupture of the insulator. Therefore, based on the above embodiments, further improvements are made.

[0046] As Figures 2 to 5 shown, the vibration damping mechanism 6 is arranged between the support frame 2 and the connecting rod 101. The vibration damping mechanism 6 includes a sleeve 601 movably connected to the connecting rod 101. An adjusting rod 602 is movably connected inside the sleeve 601. One end of the adjusting rod 602 away from the sleeve 601 is fixedly connected to the guiding block 502. When the adjusting rod 602 slides along the sleeve 601 to the threshold value, the adjusting rod 602 drives the sleeve 601 to slide and rotate, for reducing the lateral impact force.

[0047] The shock absorption mechanism 6 further includes a shock absorption groove 603 formed in the connecting rod 101. The sleeve 601 and the adjusting rod 602 are both located in the shock absorption groove 603. A guiding groove 604 is formed on the circumferential side of the sleeve 601. An auxiliary rod 605 is fixedly connected to the inner wall of the shock absorption groove 603. The free end of the auxiliary rod 605 is inserted into the guiding groove 604. When the sleeve 601 slides, under the action of the auxiliary rod 605 and the guiding groove 604, the sleeve 601 rotates along the shock absorption groove 603. A first elastic member 606 is arranged between the shock absorption groove 603 and the sleeve 601, and a second elastic member 607 is arranged between the sleeve 601 and the adjusting rod 602. The elastic force of the first elastic member 606 is greater than that of the second elastic member 607.

[0048] During actual use, when the wire clamp 303 drives the guiding block 502 to slide downward along the placement groove 501 through the connecting block 302 and the ejector rod 304, the guiding block 502 drives the adjusting rod 602 to slide downward along the support frame 2. Since the elastic force of the first elastic member 606 is greater than that of the second elastic member 607, when the adjusting rod 602 slides downward along the sleeve 601, the second elastic member 607 is compressed. At this time, the impact force received by the wire clamp 303 is decomposed into a part of the downward force, playing a first shock absorption role.

[0049] When the wind force continues to increase, after the second elastic member 607 is compressed to the limit state, at this time, the adjusting rod 602 continues to slide downward along the connecting rod 101. The adjusting rod 602 drives the sleeve 601 to slide downward along the connecting rod 101 through the second elastic member 607, and the first elastic member 606 is compressed. An inclined guiding groove 604 is formed on the circumferential side of the sleeve 601. At the same time, under the action of the auxiliary rod 605 on the inner wall of the shock absorption groove 603, when the sleeve 601 slides downward along the shock absorption groove 603, under the combined action of the guiding groove 604 and the auxiliary rod 605, the sleeve 601 rotates along the shock absorption groove 603, thereby decomposing the downward component force into a part of the force for the rotation of the sleeve 601. At this time, not only can the impact force received by the wire clamp 303 be decomposed in multiple stages, but also the impact force is prevented from directly acting on the insulating member 102 through the connecting rod 101, reducing the influence of the impact force on the insulating member 102 and improving the service life of the insulating member 102. When the wind force gradually decreases to disappear, the above movement is repeated in reverse, so that the wire clamp 303 drives the cable to return to the central position of the support frame 2 and remain stable.

[0050] In summary, through the settings of the sleeve 601, the adjusting rod 602, the first elastic member 606, the second elastic member 607, the guiding groove 604 and the auxiliary rod 605, not only can the impact force received by the wire clamp 303 be decomposed into a downward force to overcome the elastic force of the second elastic member 607 for primary shock absorption, but also the force exceeding the threshold value of the second elastic member 607 can be decomposed again through the sleeve 601, and the sleeve 601 is rotated to reduce the impact force. At this time, it can be avoided that the excessive impact force directly acts on the insulating member 102 through the support frame 2 and the connecting rod 101. Through the multi-stage shock absorption and decomposition of the impact force, the influence of the impact force on the insulating member 102 in the long term is effectively prevented, the internal fragmentation of the insulating member 102 in bad weather is avoided, and at the same time, the service life of the insulating member 102 can be effectively improved.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
