Description

Technical Field

[0001] This application relates to the field of power fittings technology, and in particular to a tension-resistant connection device. Background Technology

[0002] Compression-type tension clamps are widely used in high-voltage and ultra-high-voltage transmission lines to fix and bear the tension of conductors. They are one of the important hardware components in the power system, and their service life directly affects the safety and reliability of the transmission line.

[0003] Because compression-type tension clamps require hydraulic tools for crimping, the wire is usually crimped to the steel anchor on the ground first, and then crimped to the clamp body to form a hexagonal prism. The diversion plate is then installed on the transmission tower. Traditional compression-type tension clamps use two metal plates stacked together and fixed with bolts for the diversion plate.

[0004] Traditional compression-type tension clamps using bolts to connect the current-carrying plate have the following problems: Firstly, bolt holes need to be machined into the current-carrying plate. During this process, scratches and defects may appear on the surface of the current-carrying plate due to drilling and grinding. These scratches and defects allow dust and rainwater to corrode the current-carrying plate, affecting the current-carrying quality. Secondly, due to the lack of standardized operating procedures, it is difficult to achieve the required bolt preload for fixing the current-carrying plate. Thirdly, the gap between the bolt hole diameter and the bolt diameter in the compression-type tension clamp's current-carrying plate is not clearly defined, allowing rainwater, dust, and other debris to seep in and corrode the current-carrying plate. Finally, the problems caused by bolted connections can lead to overheating of the current-carrying plate, severely affecting power supply quality. In high-voltage lines, to solve these problems, the current-carrying plate needs to be replaced. Replacing the current-carrying plate may require regional power outages or load reductions, resulting in significant economic losses. Summary of the Invention

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification. Example 1

[0027] like Figure 1 As shown, the first aspect of this application discloses a drainage plate 1, including: a drainage plate body 11 and a first force transfer component 12; the drainage plate body 11 has a first surface and a second surface facing away from each other, the second surface being used to fit the drainage area A of the wire clamp 2; the first force transfer component 12 is disposed on the first surface, the first force transfer component 12 has a first connecting end and a traction end, the first connecting end being used to connect with the second connecting end of the second force transfer component 22 of the wire clamp 2, and the traction end being used to connect with the driving end of the driving component 24 of the wire clamp 2; wherein, the traction end can be pulled by the driving end, so that the first connecting end and the second connecting end abut against each other, and the driving force of the driving component 24 is transferred into the second surface area of ​​the plate area resisting the drainage area A of the wire clamp 2.

[0028] Specifically, the shape of the drainage plate body 11 is not specifically limited; it can be a curved plate or a straight plate. Its specific shape is selected according to the shape of the drainage area A of the wire clamp body 21, as long as the drainage plate body 11 is in close contact with the drainage area A of the wire clamp body 21. The material of the drainage plate body 11 is not specifically limited, as long as it can achieve the drainage function.

[0029] The first force transfer component 12 can be a top groove with a collar. The groove surface of the top groove is the first connecting end, and the collar is the traction end. The top groove can be directly opened on the diversion plate body 11 or it can be integrally formed with the diversion plate body 11. In this case, the second force transfer component 22 is provided with a fixed cam. The cam fits against the groove surface of the top groove. The drive component 24 pulls the collar so that the cam presses against the top groove, converting the driving force of the drive component 24 into the top force of the diversion plate 1 against the clamp 2.

[0030] The first force transfer component 12 can also be two linkage components, which are slidably connected to both sides of the diversion plate body 11. Each linkage component has a slider 122, and the second force transfer component 22 has a slide rail. The slider 122 is slidably connected to the slide rail. When the driving component 24 drives the linkage components to move synchronously in the same direction, the slider 122 on the linkage component abuts against the slide rail, converting the driving force of the driving component 24 into a resisting force of the diversion plate body 11 against the wire clamp 2. Specifically, the first force transfer component 12 is not limited; it can cooperate with the second force transfer component 22 to transfer the driving force of the driving component 24 into a resisting force of the diversion plate 1 against the wire clamp 2.

[0031] Compared with the prior art, the drainage plate 1 provided in the first aspect of this application includes: a drainage plate body 11 and a first force transfer component 12. The drainage plate body 11 has a first surface and a second surface that are opposite to each other. The second surface is used to fit the drainage area A of the wire clamp body 21 in the wire clamp 2 provided in the second aspect of this application. The first force transfer component 12 is disposed on the first surface. The first force component has a first connecting end and a traction end. The first connecting end is connected to the second connecting end of the second force transfer component 22 of the wire clamp 2. The traction end is connected to the driving end of the driving component 24 of the wire clamp 2. The traction end is pulled by the driving end of the driving component 24, so that the first connecting end and the second connecting end abut against each other, and the driving force of the driving component 24 is transferred into the second surface area of ​​the plate area resisting the drainage area A of the wire clamp 2. The current-draining plate 1 provided in the first aspect of this application, together with the wire clamp 2 in the second aspect of this application, forms a tension-resistant connection device. The driving force of the driving component 24 is transferred to the current-draining plate body 11 against the wire clamp body 21 through the first force transfer component 12 and the second force transfer component 22. This replaces the bolt fixing between the current-draining plates 1 in the prior art, effectively preventing the corrosion and overheating of the current-draining plate caused by the bolt connection, which affects the power supply quality and causes serious economic losses.

[0032] In some embodiments, the body 11 of the drainage plate is a long strip-shaped arc plate, with the outer protruding surface of the arc plate being the first surface and the inner concave surface of the arc plate being the second surface.

[0033] Specifically, the elongated arc-shaped plate can be tightly fitted to the elongated tubular wire clamp body 21. The curvature and length of the elongated arc-shaped plate are not specifically limited; its curvature is selected based on the curvature of the wire clamp body 21's surface, and its length is determined based on the actual drainage requirements. The tight fit between the elongated arc-shaped plate and the elongated tubular wire clamp body 21 reduces the entry of rainwater, dust, and other debris through gaps, thus preventing corrosion of the drainage plate body 11 and increasing its lifespan.

[0034] like Figure 2As shown, in some embodiments, the first force transfer component 12 includes: at least four first connecting rods 121, two sliders 122, and a traction part 123; one end of each of the at least four first connecting rods 121 is rotatably connected to the first and second edge positions opposite to the width direction of the first surface of the diversion plate body 11, and the first connecting rods 121 on the first and second sides are symmetrical; the sliders 122 are elongated, and the two sliders 122 are rotatably connected to the other ends of the first connecting rods 121 on the first and second sides, respectively, and form parallelogram structures on the first and second sides, respectively; the two sliders 122 are first connecting ends, and the two sliders 122 are respectively used to slide in connection with the two first slide rails 223 of the second force transfer component 22; the traction part 123 is simultaneously connected to the two sliders 122, and the traction part 123 has a traction end.

[0035] Specifically, the exact number of the first connecting rods 121 is not limited and is selected based on the length of the drainage plate body 11, as long as it ensures that the drainage plate body 11 is subjected to even and stable force. The rotatable connection between one end of the first connecting rod 121 and the drainage plate body 11 can be achieved by setting a slot at the first and second opposite edges in the width direction of the drainage plate body 11, and simultaneously setting a bearing at one end of the first connecting rod 121, inserting the bearing into the slot to achieve the rotatable connection. Alternatively, a rotating shaft can be set at the first and second opposite edges in the width direction of the drainage plate body 11, with a bearing at one end of the first connecting rod 121. This rotating shaft can be integrally formed with the drainage plate body 11, and the bearing can be fitted into the rotating shaft to achieve rotation. The specific connection method is not limited, as long as it allows rotation between the first connecting rod 121 and the drainage plate body 11, and the connection is stable and can withstand significant force.

[0036] The rotatable connection between the two sliders 122 and the other end of the first connecting rod 121 can be achieved through the cooperation of bearings and rotating shafts, or by setting through holes in the sliders 122 and setting rotating shafts at the other end of the first connecting rods 121, achieving rotation through the through holes and rotating shafts. The specific connection method is not limited, as long as relative rotation is achieved, the connection is stable, and it can withstand a certain force. The traction part 123 can be a T-shaped rod or a connector with multiple connecting ends; its specific form is not limited. It can be driven by the drive assembly 24 and can drive the synchronous movement of the two sliders 122. In this embodiment, the two sliders 122 can be slidably connected to the two first slide rails 223 in the clamp 2. The parallelogram structure formed by the two sliders 122 and at least four first connecting rods 121, when the first connecting rods 121 rotate to the point where the parallelogram structure is rectangular, the vertical distance between the two sliders 122 and the diversion plate body 11 is greater than the vertical distance between the first slide rails 223 and the diversion plate body 11.

[0037] The first force transfer component 12 provided in this embodiment has a simple structure. It can work with the second force transfer component 22 to transfer the driving force of the driving component 24 into the resisting force of the diversion plate body 11 against the clamp body 21. The resisting force can be adjusted by adjusting the rotation angle of the first connecting rod 121 relative to the diversion plate body 11.

[0038] In some embodiments, the traction unit 123 includes: a third connecting rod 1231 and a rack 1232; one end of the third connecting rod 1231 is simultaneously connected to the relative positions of the two sliders 122; the rack 1232 is connected to the other end of the third connecting rod 1231, and the rack 1232 forms the traction end.

[0039] Specifically, the form of the third connecting rod 1231 is not limited. One end has two corresponding connecting ends for connecting the corresponding positions of the two sliders 122. The other end, facing away from each other, is provided with a rack 1232. The rack 1232 can mesh with the gear structure 242 at the driving end of the drive assembly 24. By adjusting the rotation of the gear structure 242, the traction end of the first force transfer assembly 12 is pulled. The driving force of the drive assembly 24 is input into the force transfer system composed of the first drive assembly 24 and the second drive assembly 24 through the cooperation of the rack 1232 and the gear structure 242 in the drive assembly 24. The structure is simple and stable. At the same time, the rack 1232 can be marked according to actual needs and calculations. The rack 1232 is pulled by the gear structure 242 according to the marked points, thereby controlling the abutment of the diversion plate body 11 against the line clamp body 21 to a suitable force, thereby increasing the diversion effect. Example 2

[0040] like Figure 3 As shown, a second aspect of this application provides a wire clamp 2, comprising: a wire clamp body 21, a second force transfer component 22, a first connecting portion 23, and a driving component 24; the wire clamp body 21 has a compression region B and a drainage region A, the drainage region A being used to fit against the second surface of the drainage plate body 11; the second force transfer component 22 is disposed on the drainage region A, the second force transfer component 22 having a second connecting end, the second connecting end being used to connect to the first connecting end of the first force transfer component 12 of the drainage plate 1; one end of the first connecting portion 23 is connected to the steel anchor end of the wire clamp body 21, and the other end of the first connecting portion 23 is used to connect to an insulator; the driving component 24 is disposed on the first connecting portion 23, the driving component 24 being used to connect to the traction end of the first force transfer component 12; wherein, the driving component 24 pulls the traction end, causing the first connecting end and the second connecting end to abut against each other, transferring the driving force of the driving component 24 into a resisting force of the second surface of the drainage plate 1 against the drainage region A of the wire clamp 2.

[0041] Specifically, the clamp body 21 can be a long tubular clamp 2. The positions of the drainage area A and the compression area B are not limited in this embodiment. The drainage area A can be a metal plate welded on the clamp 2, combined with a straight plate drainage plate body 11, or it can be a long arc plate directly attached to the area of ​​the clamp body 21 that has not been compressed.

[0042] The second force transfer component 22 can be a fixed cam set on a fixed space. The fixed cam is the second connecting end. The protruding end of the fixed cam fits into the abutting groove in the first force transfer component 12. The drive component 24 pulls the collar in the first force component to make the cam press against the abutting groove, and converts the driving force of the drive component 24 into the abutting force of the diverting plate 1 against the line clamp 2.

[0043] The second force transfer component 22 can also be a slide rail disposed on both sides of the drainage area A. The length direction of the slide rail is parallel to the length direction of the clamp body 21, and it is slidably connected to the slider 122 on the connecting rod assembly disposed on both sides of the drainage plate body 11. When the drive component 24 drives the connecting rod assembly to move synchronously in the same direction, the slider 122 disposed on the connecting rod assembly presses against the slide rail, converting the driving force of the drive component 24 into the resisting force of the drainage plate 1 on the clamp 2. The second force transfer component 22 is not specifically limited. The second force transfer component 22 can cooperate with the first force transfer component 12 to transfer the driving force of the drive component 24 into the resisting force of the drainage plate 1 on the clamp 2.

[0044] The first connecting part 23 can be a connecting plate or a connecting block, with two opposing connecting holes on the connecting block. Its specific form is not limited. It only needs to achieve a stable connection between the steel anchor and the insulator of the clamp body 21. In this embodiment, the first connecting part 23 can be a connecting block, with a connecting hole at one end for connecting the insulator and a threaded hole at the other end. The first connecting part 23 also includes a U-shaped frame, with threaded holes at both ends corresponding to the threaded holes of the connecting block, and connected by bolts. During installation, the U-shaped frame can be first fitted onto the steel anchor, and then bolted to connect the U-shaped frame to the connecting block. The structure is simple and installation is convenient.

[0045] The drive component 24 is not specifically limited; it can be a gear that can be limited or a lead screw and nut pair. The specific choice can be made according to the structure of the traction end, as long as it can achieve traction of the traction end.

[0046] Compared with the prior art, the wire clamp 2 provided in the second aspect of this application includes: a wire clamp body 21, a second force transfer component 22, a first connecting part 23, and a driving component 24; the drainage area A of the wire clamp body 21 is in contact with the second surface of the drainage plate body 11; the second force component is disposed at the drainage area A and has a second connecting end, and the first connecting end is used to connect with the first connecting end of the first force transfer component 12 of the drainage plate 1; one end of the first connecting part 23 is connected to the steel anchor of the wire clamp body 21, and the other end is connected to the insulator; the driving component 24 is disposed on the first connecting part 23 and is used to connect with the traction end of the first force transfer component 12; the driving component 24 pulls the traction end, so that the first connecting end and the second connecting end abut against each other, and the driving force of the driving component 24 is transferred into the abutting force of the second surface of the drainage plate 1 against the drainage area A of the wire clamp 2. The driving force of the drive component 24 is transferred to the resisting force of the drain plate body 11 against the clamp body 21 by the first force transfer component 12 and the second force transfer component 22. This replaces the bolt fixing between the drain plates 1 in the prior art, effectively preventing the problem of corrosion and heat generation of the drain plate caused by the bolt connection of the drain plate, which affects the power supply quality and causes serious economic losses.

[0047] In some embodiments, the drainage area A of the clamp body 21 is located in the middle of the clamp body 21, and the remaining part is the compression area B.

[0048] In this embodiment, the clamp body 21 is a long tubular shape, with the middle area left untreated. The second force transfer component 22 is set in this area, and the two sides are the compression areas B. With this design, the structural space span of the clamp body 21 is small, and the compression area B is only used for receiving rather than for draining. Therefore, when performing the compression process, the operator does not need to pay attention to whether the compression area B of the clamp body 21 is scratched or damaged.

[0049] In some embodiments, the second force transfer component 22 includes: two first support rods 221, two second support rods 222, and two first slide rails 223; one end of each of the two first support rods 221 is symmetrically connected to both sides of the drainage area A near the first connecting portion 23; one end of each of the two second support rods 222 is symmetrically connected to both sides of the drainage area A away from the first connecting portion 23, the two first support rods 221 and the two second support rods 222 point in the same direction, and the distance between the two second support rods 222 is greater than the distance between the two first support rods 221; both ends of the two first slide rails 223 are connected to the other ends of the two first support rods 221 and the two second support rods 222, respectively, and the end of the slide rail that is close to the second support rod 222 is provided with an installation opening; the two first slide rails 223 are second connecting ends, and the two first slide rails 223 can be slidably connected to the two sliders 122 of the first force transfer component 12, respectively.

[0050] The connection between the two first support rods 221 and the drainage area A of the wire clamp 2 can be achieved by setting a protruding mounting seat on the wire clamp 2 and then welding the first support rods 221 to the mounting seat, or by setting a slot and inserting the first support rods 221 into the slot to achieve the connection. The specific connection method is not limited, as long as a stable connection can be achieved and separation or deformation does not occur during the operation.

[0051] The connection between the two second support rods 222 and the drainage area A of the clamp 2 can be achieved by either setting a protruding mounting base on the clamp 2 and then welding the second support rods 222 to the mounting base, or by setting a slot and inserting the second support rods 222 into the slot. The specific connection method is not limited, as long as a stable connection is achieved and separation or deformation does not occur during operation. The distance between the two second support rods 222 is greater than the distance between the two first support rods 221. The specific distance is not limited, but it must ensure that the two first support rods 221 can block the drainage plate 1. The distance between the two second support rods 222 must ensure that the drainage plate 1 can pass laterally between the two second support rods 222 during operation. This structure, while blocking the drainage plate 1, also allows for smooth placement of the drainage plate 1 into the drainage area A and prevents the drainage plate 1 from falling off due to shaking after installation. Meanwhile, the two first brackets on the side of the clamp body 21 near the first connecting part 23 are used to solve the problem that the arc plate may be misaligned due to excessive pressure and excessive forward sliding.

[0052] The connection method between the two first slide rails 223 and the first support rod 221 and the second support rod 222 is not specifically limited. It can be that connecting seats are provided on the two first slide rails 223, and the connecting seats are welded to the first support rod 221 and the second support rod 222 respectively. Alternatively, a slot is provided on the first slide rail 223, and the first support rod 221 and the second support rod 222 are inserted into the slot. The specific connection method is not limited, as long as a stable connection is achieved and separation or deformation does not occur during operation. One end of the first slide rail 223 that abuts the second support rod 222 has an installation opening, allowing the slider 122 of the first force transfer assembly 12 to be directly inserted into the first slide rail 223 through the opening, thus achieving connection between the slider 122 and the first slide rail 223 and facilitating installation. In this embodiment, the two sliders 122 can be slidably connected to the two first slide rails 223 in the wire clamp 2. The parallelogram structure formed by the two sliders 122 and at least four first connecting rods 121, when the first connecting rods 121 rotate to the point where the parallelogram structure is rectangular, the vertical distance between the two sliders 122 and the diversion plate body 11 is greater than the vertical distance between the first slide rail 223 and the diversion plate body 11.

[0053] like Figure 4 As shown, in some embodiments, the drive assembly 24 includes: a housing 241 and a gear structure 242; the housing 241 is provided with a through hole; disposed inside the housing 241, one end of the axle of the gear structure 242 protrudes from the side wall of the first connecting part 23 and is provided with an adjustment part, the gear structure 242 is used to output driving force, and the rack 1232 of the first force transfer assembly 12 can pass through the through hole and mesh with the gear structure 242.

[0054] The outer casing 241 is mounted on the first connecting part 23. The first connecting part 23 can also be integrated with the outer casing 241 to form an L-shaped structure. The length direction of the through hole on the outer casing 241 is parallel to the length direction of the clamp body 21 and is on the same side as the first force transfer component 12. The gear structure 242 is connected to the outer casing 241 by setting a rotating shaft inside the outer casing 241, with the gear and the rotating shaft having an interference fit, or by a fixed connection. In this case, a part of the rotating shaft protrudes from the outer casing 241, and an internal hexagonal structure is set on the protruding part. In this case, the internal hexagonal structure serves as an adjustment part. The specific structure of the adjustment part is not limited; the gear can be rotated by adjusting the adjustment part. This structure is simple, and only the adjustment part needs to be adjusted to achieve the abutment of the drain plate body 11 against the clamp body 21. It is convenient to operate and reduces the construction burden on operators. At the same time, the sharp corners of the drain plate 1 and the clamp 2 can be rounded to reduce corona discharge caused by the sharp corner structure.

[0055] In some embodiments, the wire clamp 2 further includes: a second slide and a retaining member 25; the second slide is disposed on the same side of the first connecting portion 23 as the driving component 24 and close to the driving component 24, and the length direction of the second slide is parallel to the length direction of the through hole; the retaining member 25 is slidably connected to the second slide, and the retaining member 25 slides along the second slide to retain or release the retaining rack 1232.

[0056] Specifically, the retaining member 25 can be a bent member, with one side of the bent member engaging in the second slide rail, and the other side engaging the rack 1232. The specific structure of the retaining member 25 is not limited; it can slide through the second slide rail and engage the rack 1232. Using the retaining member 25 and the second slide rail simplifies and stabilizes the positioning of the rack 1232. Example 3

[0057] like Figure 5 As shown, a third aspect of this application provides a tension-resistant connection device, comprising: a drain plate 1 and a clamp 2; the second surface of the drain plate 1 is attached to the drain area A of the clamp body 21 of the clamp 2; the first connecting end of the first force transfer component 12 of the drain plate 1 is connected to the second connecting end of the second force transfer component 22 of the clamp 2; the traction end of the first force transfer component 12 is connected to the driving end of the driving component 24 of the clamp 2; wherein, the driving end pulls the traction end, causing the first connecting end and the second connecting end to abut against each other, thereby transferring the driving force of the driving component 24 into a resisting force of the second surface of the drain plate 1 against the drain area A of the clamp 2.

[0058] Specifically, the tension connection device described in this embodiment three can directly use the diversion plate 1 and wire clamp 2 proposed in embodiments one and two above. For the specific implementation structure, please refer to the relevant content described in embodiment one above, which will not be repeated here.

[0059] In this embodiment, the installation method of the tension connection device can be: Step 1: On the ground, first insert the conductor 3 into the clamp body 21, and then compress the steel anchor and the end of the conductor 3 using a hydraulic device. Next, compress the conductor 3 and the compression area B of the clamp body 21, and simultaneously compress the steel anchor and the compression area B of the clamp body 21. Step 2: On the ground, connect the steel anchor of the clamp body 21 to the first connecting part 23, and suspend the wire 3; Step 3: Connect the first connecting part 23 to the insulator in mid-air; Step 4: On the ground, connect the jumper cable to the jumper cable connection end of the diversion plate body 11 and compress it using hydraulic equipment; Step 5: In the air, the diversion plate body 11 is inserted from one side of the second support rod 222 and the second surface is made to fit against the diversion area A. At the same time, the slider 122 is inserted into the slide through the installation opening of the first slide 223. Step 6: In the air, the rack 1232 passes through the through hole provided on the housing 241 of the drive assembly 24 and meshes with the gear structure 242; Step 7: In the air, by adjusting the adjustment part, the gear structure 242 drives the rack 1232, and at the same time, the two sliders 122 slide in the first slide rail 223 towards the first connecting part 23. Step 9: In the air, adjust the rack 1232 to the preset position, slide the retaining member 25 to engage with the rack 1232, and limit the rack 1232.

[0060] In this embodiment, by adjusting the adjustment part, the gear structure 242 drives the rack 1232, thereby causing the traction part 123 to drive the two sliders 122 to slide towards the first connecting part 23. Since the two sliders 122 and at least four first connecting rods 121 form a parallelogram structure, when the first connecting rods 121 rotate to the point where the parallelogram structure is rectangular, the vertical distance between the two sliders 122 and the diversion plate body 11 is greater than the vertical distance between the first slide rail 223 and the diversion plate body 11. Therefore, when the two sliders 122 slide towards the first connecting part 23, they gradually press against the two first slide rails 223. At this time, the two first slide rails 223 also react on the two sliders 122, thereby pushing the diversion plate body 11 through the first connecting rods 121, causing the diversion plate body 11 to press against the wire clamp body 21. It replaces the bolt fixing between the current-generating plates 1 in the existing technology, effectively preventing the corrosion and overheating of the current-generating plates caused by bolt connection, which affects the power supply quality and thus causes serious economic losses.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
