Description

Technical Field

[0001] This invention belongs to the field of power auxiliary equipment technology, specifically a transmission line optimization auxiliary device for complex environments. Background Technology

[0002] Power line galloping is a low-frequency, large-amplitude vibration phenomenon of power lines that occurs under specific meteorological conditions, usually triggered by factors such as wind excitation, icing, or temperature changes. It is extremely dangerous, potentially causing fatigue fracture of the conductors, damage to fittings, flashover of insulators, and even collapse accidents, seriously threatening the safe and stable operation of the power grid.

[0003] Typically, operators connect split conductors into a single unit by installing spacers to improve the system's rigidity and stability. However, installing spacers requires working at heights, making construction difficult and inefficient. For high-voltage transmission lines, the conductors are long and have large diameters, resulting in a significant mass per unit length. Furthermore, the conductors naturally exhibit sag and tension distribution, requiring operators to manually pull the remaining conductors to the clamping components on the spacer after installing the spacer on one conductor. Working at heights reduces the operator's stress points, is time-consuming and labor-intensive, and increases the risk of injury. Therefore, to address these issues, an optimization auxiliary device for transmission lines in complex environments is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an auxiliary device for optimizing power transmission lines in complex environments, which solves the problem of reduced installation efficiency due to the time and effort required for operators to install spacers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transmission line optimization auxiliary device under complex environment, comprising two sets of connecting rod assemblies and a connecting block II, and further comprising: a clamping assembly symmetrically mounted on the connecting rod assemblies; and a screw assembly disposed on the connecting rod assemblies for spreading the connecting rod assemblies apart so that they drive the two sets of clamping assemblies to move toward each other;

[0006] The connecting block 2 is used to connect two sets of screw assemblies and make the two sets of screw assemblies perpendicular to each other;

[0007] The connecting rod assembly includes two connecting rod 1s, two connecting rod 3s, and four connecting rod 2s. The two ends of the connecting rod 1s are respectively hinged to one end of the two connecting rod 2s, and the two ends of the connecting rod 3s are respectively hinged to the other end of the two connecting rod 2s.

[0008] The clamping assembly includes a spring combination rod 1 fixed to the three sides of the connecting rod. A connecting block 1 is sleeved on the outside of the spring combination rod 1. The spring portion of the spring combination rod 1 is located between the connecting block 1 and the connecting rod 3. A sleeve 2 is fixed to one side of the connecting block 1. The connecting rod 3 is also elastically connected to the spring combination rod 2. One end of the spring combination rod 2 passes through the connecting rod 3, the connecting block 1, and the sleeve 2. A clamp 1 is fixed to one end of the spring combination rod 2. A clamp 2 is hinged to one end of the clamp 1. A guide groove 2 is provided on the sleeve 2. A convex shaft that can slide along the guide groove 2 is fixed to the clamp 2.

[0009] The bottom of the second guide groove is trumpet-shaped. When the second clamp drives the convex shaft to rotate around the axis, the convex shaft can squeeze the opening of the second guide groove and make the second sleeve move toward the first clamp.

[0010] Preferably, insulating gaskets are fixedly connected to both clamp one and clamp two.

[0011] Preferably, the second sleeve is further provided with a first guide groove that communicates with one end of the second guide groove. The first guide groove is inclined and the convex shaft can slide from the second guide groove into the first guide groove.

[0012] Preferably, when the convex shaft is engaged at the connection between guide groove two and guide groove one, there is still a gap between the locking end of clamp two and clamp one;

[0013] When the convex shaft moves within the guide groove, it can completely close clamp one and clamp two.

[0014] Preferably, the screw assembly includes a screw member and a sleeve fixed to a connecting rod, the two ends of the screw member are respectively threaded to two sleeves, and a hexagonal block is provided in the middle of the screw member;

[0015] The screw is movably sleeved on the connecting block 2 and is axially limited by the connecting block 2;

[0016] The rotating hexagonal block can drive the screw to rotate and cause the two sleeves to move in opposite directions.

[0017] Preferably, a ratchet is fixedly connected to the middle of the screw, and an elastic pawl that can engage with the ratchet is elastically supported inside the hexagonal block.

[0018] Preferably, a fixing component is provided on the second connecting rod in one group of the connecting rod assemblies, and a slot is provided on the second connecting rod in the other group of the connecting rod assemblies to engage with the fixing component;

[0019] When the connecting rods in the two sets of connecting rod assemblies overlap, the fixing component can be engaged in the slot.

[0020] Preferably, the fixing component includes a spring combination rod three elastically connected to the connecting rod two. One end of the spring combination rod three is fixedly connected to a conical locking block. When the conical locking block is squeezed by the connecting rod two in another set of connecting rod assemblies, it can retract into the connecting rod two. When the locking groove and the spring combination rod three coincide, the conical locking block will be locked into the locking groove by the elastic force of the spring part of the spring combination rod three.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The above solution involves attaching clamp one to the transmission line, rotating clamp two to drive the convex shaft to press against the flared opening of guide groove two, thereby causing sleeve two and connecting block one to move towards clamp one and stretching the spring part of spring combination rod one. When the convex shaft moves to the end of guide groove two and guide groove one, sleeve two and connecting block one will be reset by the tension of spring combination rod one. At this time, the convex shaft is stuck at the end of guide groove two, thereby fixing the transmission line between two sets of insulating pads. Then, the operator rotates one set of hexagonal blocks to drive the screw to rotate, thereby causing the two sleeves one to drive the connecting rod one to move in opposite directions. At the same time, the connecting rod one will also drive the connecting rod three to move in opposite directions through the connecting rod two at both ends, thereby making the transmission line fixed by the clamping assembly closer to each other. Then, the other set of connecting rod assembly, screw assembly and clamping assembly are repeated to achieve the separation of the transmission line and connect it into a whole to improve installation efficiency and safety.

[0023] When the above scheme moves through one set of connecting rod assemblies, the conical block on it will be squeezed by the edge of the connecting rod two in the other set of connecting rod assemblies, causing the conical block to retract into the connecting rod two. When the other set of connecting rod assemblies also deforms, the corresponding connecting rod two on the two sets of connecting rod assemblies will overlap. At this time, under the elastic force of the spring combination rod three, the conical block will be locked into the slot. With the support of the two sets of extended screw assemblies, the two sets of connecting rod assemblies will maintain a stable state to separate the power transmission line.

[0036] 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.

[0037] like Figures 1 to 11 As shown, the present invention provides a transmission line optimization auxiliary device in complex environments, including two sets of connecting rod assemblies 1 and a second connecting block 4, and further including: a clamping assembly 3, which is symmetrically installed on the connecting rod assembly 1; a screw assembly 2, which is disposed on the connecting rod assembly 1 for spreading the connecting rod assembly 1 so that it drives the two sets of clamping assemblies 3 to move towards each other; wherein, the second connecting block 4 is used to connect the two sets of screw assemblies 2 and make the two sets of screw assemblies 2 in a vertical state;

[0038] The connecting rod assembly 1 includes two connecting rods 11, two connecting rods 3 13 and four connecting rods 2 12. The two ends of the connecting rods 11 are respectively hinged to one end of the two connecting rods 2 12, and the two ends of the connecting rods 3 13 are respectively hinged to the other end of the two connecting rods 2 12.

[0039] The clamping assembly 3 includes a spring combination rod 31 fixed to the side of the connecting rod 3 13. A connecting block 32 is sleeved on the outside of the spring combination rod 31. The spring part on the spring combination rod 31 is located between the connecting block 32 and the connecting rod 3 13. A sleeve 34 is fixed to one side of the connecting block 32. A spring combination rod 33 is also elastically connected to the connecting rod 3 13. One end of the spring combination rod 33 passes through the connecting rod 3 13, the connecting block 32 and the sleeve 34. A clamp 36 is fixed to one end of the spring combination rod 33. A clamp 37 is hinged to one end of the clamp 36. A guide groove 35 is opened on the sleeve 34. A convex shaft 38 that can slide along the guide groove 35 is fixed to the clamp 37.

[0040] The bottom of the guide groove 2 35 is trumpet-shaped. When the clamp 2 37 drives the convex shaft 38 to rotate around the shaft, the convex shaft 38 can squeeze the opening of the guide groove 2 35 and make the sleeve 2 34 move toward the clamp 1 36. Insulating gaskets 371 are fixed on both the clamp 1 36 and the clamp 2 37.

[0041] The screw assembly 2 includes a screw member 22 and a sleeve 21 fixed to the connecting rod 11. The two ends of the screw member 22 are threadedly connected to the two sleeves 21 respectively. A hexagonal block 23 is provided in the middle of the screw member 22. The screw member 22 is movably sleeved on the connecting block 24 and is axially limited by the connecting block 24. Rotating the hexagonal block 23 can drive the screw member 22 to rotate and drive the two sleeves 21 to move in opposite directions.

[0042] Using the above scheme, after clamp 36 is attached to the power transmission line, clamp 37 is rotated to drive cam 38 to press against the flared end of guide groove 35. This causes sleeve 34 and connecting block 32 to move toward clamp 36, stretching the spring portion of spring combination rod 31. As cam 38 moves to the end of guide groove 35 and guide groove 341, sleeve 34 and connecting block 32 are reset by the tension of spring combination rod 31. At this time, cam 38 is stuck at the end of guide groove 35, thus securing the power transmission line. The device is positioned between two sets of insulating pads 371. Then, the operator rotates one set of hexagonal blocks 23, which drives the screw component 22 to rotate. This causes the two sleeves 1 21 to move the connecting rod 1 11 in opposite directions. At the same time, the connecting rod 1 11 will also drive the connecting rod 3 13 to move towards each other through the connecting rods 2 12 at both ends. This causes the power transmission lines fixed by the clamping component 3 to move closer to each other. Then, the above operation is repeated with another set of connecting rod components 1, screw components 2 and clamping components 3, so as to quickly separate the power transmission lines and connect them into a whole to improve installation efficiency and safety.

[0043] like Figures 4-6 As shown, the sleeve 2 34 is also provided with a guide groove 1 341 that communicates with one end of the guide groove 2 35. The guide groove 1 341 is in an inclined state, and the convex shaft 38 can slide from the guide groove 2 35 into the guide groove 1 341.

[0044] When the convex shaft 38 is inserted into the connection between guide groove 2 35 and guide groove 1 341, there is still a gap between the locking end of clamp 2 37 and clamp 1 36.

[0045] When the convex shaft 38 moves within the guide groove 341, it can completely close the clamp 36 and the clamp 37.

[0046] Using the above scheme, during the mutual movement of the connecting rod 313, the spring combination rod 31 will first drive the spring combination rod 33 and the sleeve 34 to move through the connecting block 32. The movement of the sleeve 34 will drive the guide groove 341 to move, thereby forcing the convex shaft 38 to slide in the guide groove 341. This allows the clamps 36 and 37 to tighten the clamping of the power transmission line, and also makes it easier for the operator to quickly clamp the clamps 36 and 37 onto the power transmission line.

[0047] like Figure 7 and Figure 8 As shown, a ratchet 221 is fixedly connected to the middle of the screw component 22, and an elastic pawl 231 that can engage with the ratchet 221 is elastically supported inside the hexagonal block 23.

[0048] Using the above scheme, when the operator uses a wrench to rotate the hexagonal block 23, the operator does not need to put the wrench back after rotating the hexagonal block 23 to a certain angle. The operator only needs to rotate the wrench in the opposite direction to drive the hexagonal block 23 and the elastic pawl 231 to rotate in the opposite direction. At this time, the elastic pawl 231 will slide relative to the ratchet 221. After the hexagonal block 23 returns to its initial angle, the operator can continue to rotate the hexagonal block 23 to drive the screw 22 to rotate and drive the two sleeves 21 to move in opposite directions.

[0049] like Figures 1-2 and Figures 9-11 As shown, a fixing component 5 is provided on the second connecting rod 12 in one set of connecting rod assembly 1, and a slot 6 is provided on the second connecting rod 12 in the other set of connecting rod assembly 1 to engage with the fixing component 5; when the second connecting rod 12 in the two sets of connecting rod assembly 1 overlap, the fixing component 5 can be engaged into the slot 6.

[0050] The fixing component 5 includes a spring combination rod 3 51 elastically connected to the connecting rod 2 12. One end of the spring combination rod 3 51 is fixed with a conical block 52. When the conical block 52 is squeezed by the connecting rod 2 12 in another set of connecting rod components 1, it can retract into the connecting rod 2 12. When the slot 6 and the spring combination rod 3 51 coincide, the conical block 52 will be inserted into the slot 6 by the elastic force of the spring part of the spring combination rod 3 51.

[0051] Using the above scheme, when one set of connecting rod assemblies 1 moves, the conical block 52 on it will be squeezed by the edge of the connecting rod 12 in the other set of connecting rod assemblies 1, thereby causing the conical block 52 to retract into the connecting rod 12. When the other set of connecting rod assemblies 1 also deforms, the corresponding connecting rods 12 on the two sets of connecting rod assemblies 1 will overlap. At this time, under the elastic force of the spring combination rod 3 51, the conical block 52 will be inserted into the slot 6. At the same time, with the support of the two sets of extended screw assemblies 2, the two sets of connecting rod assemblies 1 will maintain a stable state to separate the power transmission line.

[0052] Working principle and usage process of this invention:

[0053] First, the operator attaches clamp 36 to the power transmission line. Then, by rotating clamp 37, the convex shaft 38 is forced to press against the flared end of guide groove 35. This causes sleeve 34 and connecting block 32 to move towards clamp 36, stretching the spring portion of spring rod 31. As the convex shaft 38 moves to the end of guide groove 35 and guide groove 341, sleeve 34 and connecting block 32 are reset by the tension of spring rod 31. At this point, the convex shaft 38 is stuck at the end of guide groove 35, thus... The transmission line is fixed between two sets of insulating pads 371. Then, the operator rotates one set of hexagonal blocks 23 to drive the screw 22 to rotate, thereby causing the two sleeves 1 21 to drive the connecting rod 1 11 to move in opposite directions. At the same time, the connecting rod 1 11 will also drive the connecting rod 3 13 to move in opposite directions through the connecting rods 2 12 at both ends, thereby bringing the transmission line fixed by the clamping assembly 3 closer to each other. Then, the above operation is repeated with another set of connecting rod assembly 1, screw assembly 2 and clamping assembly 3, thereby quickly separating the transmission line and connecting it into a whole.

[0054] During the mutual movement of the connecting rods 3 and 13, the first spring combination rod 31 will drive the second spring combination rod 33 and the second sleeve 34 to move through the first connecting block 32. The movement of the second sleeve 34 will drive the first guide groove 341 to move, thereby forcing the convex shaft 38 to slide in the first guide groove 341. This will cause the first clamp 36 and the second clamp 37 to tighten the clamping of the transmission line. When the first clamp 36 and the second clamp 37 are fully closed, when the second sleeve 34 moves in the horizontal direction, it will drive the first clamp 36, the second clamp 37 and the transmission line to move towards each other through the cooperation between the end of the first guide groove 341 and the convex shaft 38.

[0055] When one set of connecting rod assemblies 1 moves, the conical block 52 on it will be squeezed by the edge of the connecting rod 12 in the other set of connecting rod assemblies 1, which will cause the conical block 52 to retract into the connecting rod 12. When the other set of connecting rod assemblies 1 also deforms, the corresponding connecting rods 12 on the two sets of connecting rod assemblies 1 will overlap. At this time, under the elastic force of the spring combination rod 3 51, the conical block 52 will be inserted into the slot 6. With the support of the two sets of extended screw assemblies 2, the two sets of connecting rod assemblies 1 will maintain a stable state to separate the power transmission line.
