Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line drainage equipment, and in particular relates to a temporary drainage device for a power transmission line. Background Art

[0002] With the rapid development of the economy and society, industrial, commercial, and residential users are increasingly demanding power supply reliability. Live-line work has become a crucial maintenance method for improving the economic benefits and service quality of power grids. In existing technologies, live-line drainage is a common practice in live-line work projects. This involves complex procedures, numerous hazards, and strict requirements on the physical fitness and technical skills of the operators.

[0003] When a section of a line fails and needs to be replaced or repaired, in order to ensure the normal operation of the entire transmission system, it is necessary to use a temporary diversion device to guide the current from the main line to other normal lines to avoid adverse effects such as power outages caused by line interruption.

[0004] The process of connecting the drainage device to the main line is mostly performed at height. Existing drainage devices are cumbersome to operate, wasting workers' physical energy. Furthermore, the clamping between the drainage device and the main line can easily cause an unstable connection, making the drainage device prone to tipping over and causing an unstable drainage connection, which can lead to dangers such as falling and electric shock. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to solve the problems raised in the above technical background.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a temporary drainage device for a transmission line, which includes a main body seat and an operating rod, a fixed block is provided in the middle of the main body seat, a first wire rack is fixedly provided on the front side of the fixed block, a second wire rack is fixedly provided on the rear side of the fixed block, an opening is provided on the outside of the second wire rack, a wire clamping head is movably provided on the upper side of the inside of the first wire rack, and a wire clamping head is movably provided on the lower side of the inside of the second wire rack, an adjusting screw is provided in the middle of the fixed block, a first ring is threadedly provided on the upper side of the adjusting screw, and a second ring is threadedly provided on the lower side of the adjusting screw, the first ring and the second ring are fixedly connected to the wire clamping head through a connecting rod, a ring is fixedly provided on the lower end of the adjusting screw, and a hook is fixedly provided on the upper end of the operating rod.

[0007] The internal threads of the first and second collars are in opposite directions.

[0008] A pre-clamping block is provided inside the first wire frame and is connected to the first wire frame via a pre-clamping spring. The pre-clamping block is used to pre-fix the drainage line.

[0009] A stabilizing mechanism is provided on the left and right sides of the main body seat, and the stabilizing mechanism includes a symmetrically arranged steering gear and a wire seat. The steering gear is connected to the fixed block through a bearing, and a driving rack is meshed with the outer side of the steering gear. A driving spring is provided between the upper side of the driving rack and the fixed block, and a steering arm is fixedly provided on the outer side of the steering gear, and the steering arm is connected to the wire seat at one end away from the steering gear.

[0010] The stabilizing mechanism and the position of the wire seat correspond to the position of the main line.

[0011] The wire seat is hinged to the steering arm via a rotating shaft, and the wire seat can slightly adjust the direction angle according to the position of the steering arm.

[0012] A socket is provided at the bottom of the fixing block, and the position of the socket corresponds to the position of the driving rack.

[0013] The operating lever is provided with a grip bar at the lower side, an inner shaft is movably provided inside the grip bar, a push plate is provided at the upper end of the inner shaft, and an insertion rod is provided on the upper side of the push plate, and the position of the insertion rod corresponds to the position of the insertion hole. The inner shaft can move inside the grip bar, thereby driving the push plate and the insertion rod to move.

[0014] A clamping mechanism is provided inside the wire seat, and the clamping mechanism includes a base plate, side rods are fixedly provided on the front and rear sides of the base plate, hinged hinge rings are provided at the ends of the side rods, a driving rod is provided on the side of the hinge ring close to the base plate, a clamping arm is provided on the side of the hinge ring away from the base plate, a pressure plate is provided on the outside of the base plate, and the pressure plate and the driving rod are clamped with each other.

[0015] An elastic sheet is provided between the pressing plate and the bottom plate, and the elastic sheet is clamped with the bottom plate via a sliding block.

[0016] A limiting groove is provided inside the driving rod, and a limiting block is provided at the end of the pressing plate.

[0017] The present invention provides a temporary drainage device for a power transmission line, which has the following beneficial effects: By rotating the adjustment screw and leveraging the movement of the first and second collars (with opposite internal threads) on the screw, the connecting rod activates the clamping head, quickly clamping and releasing the drainage line in the first wire rack and the main line in the second wire rack. This design is simple in structure and easy to operate, significantly reducing line clamping time and improving work efficiency.

[0018] The steering gear in the stabilization mechanism meshes with the drive rack. A drive spring moves the drive rack, which in turn rotates the steering gear, thereby changing the angle of the steering arm. The wire holder is hinged to the steering arm, allowing it to flexibly adjust to the direction and angle of the arm, allowing the device to better adapt to the main line and maintain a stable connection between the wire holder and the main line, ensuring a stable connection and positioning between the device and the line during the drainage process.

[0019] In the clamping mechanism, the pressure plate and drive rod are interlocked, and the pressure plate and base plate are connected by a spring clip. When the clamping arm clamps the circuit, the spring clip provides elastic force to tightly clamp the pressure plate to the drive rod, ensuring that the clamping arm has sufficient clamping force on the circuit, preventing the circuit from loosening and falling during the drainage process, further ensuring safe drainage.

[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] Example 1 See also Figures 1 to 4 A temporary drainage device for a transmission line, which includes a main body seat 1 and an operating rod 2, a fixed block 5 is provided in the middle of the main body seat 1, a first wire rack 3 is fixedly provided on the front side of the fixed block 5, a second wire rack 4 is fixedly provided on the rear side of the fixed block 5, an opening 6 is provided on the outside of the second wire rack 4, a wire clamping head 7 is movably provided on the upper side of the first wire rack 3, and a wire clamping head 7 is movably provided on the lower side of the second wire rack 4, an adjusting screw 8 is provided in the middle of the fixed block 5, a first collar 9 is screwed on the upper side of the adjusting screw 8, a second collar 10 is screwed on the lower side of the adjusting screw 8, the first collar 9 and the second collar 10 are fixedly connected to the collar 7 through a connecting rod 11, a collar 12 is fixed on the lower end of the adjusting screw 8, and a hook 13 is fixed on the upper end of the operating rod 2.

[0032] For better effect, the internal threads of the first sleeve ring 9 and the second sleeve ring 10 are in opposite directions. The adjusting screw 8 can simultaneously drive the first sleeve ring 9 and the second sleeve ring 10 to move closer to or away from each other.

[0033] For optimal results, a pre-clamping block 14 is installed within the first wire frame 3 and connected to the first wire frame 3 via a pre-clamping spring 15. This block 14 is used to pre-secure the drainage circuit. This block 14 provides a preliminary clamping effect on the inserted drainage circuit during the initial stage, stabilizing the circuit during the subsequent clamping process, reducing vibration, and preventing the drainage circuit from slipping or shifting during the clamping process.

[0034] When using this device, carefully check whether the main base 1, operating rod 2 and each component are intact and can be used normally. First, place the drainage line into the first wire rack 3 so that it is located below the clamping head 7 on the upper side of the first wire rack 3. The pre-clamping block 14 will generate a certain pre-clamping force on the drainage line under the action of the pre-clamping spring 15, so that the drainage line is initially fixed to prevent the drainage line from shaking during subsequent operations. Align the hook 13 at the upper end of the operating rod 2 with the ring 12 at the lower end of the adjusting screw 8 and hang them well, ensuring that the hook 13 and the ring 12 are firmly connected. Through the opening on the outside of the second wire rack 4, place the main line to be drained into the second wire rack 4 so that it is located above the clamping head 7 on the lower side of the second wire rack 4. The operator holds the operating rod 2 and drives the adjusting screw 8 to rotate. When the adjusting screw 8 rotates, the first ring 9 and the second ring 10 will move to the middle or to both ends at the same time. As the first ring 9 and the second ring 10 move, the clamping heads 7 in the first wire rack 3 and the second wire rack 4 are driven to move through the connecting rod 11, gradually clamping the main line and the drainage line at the same time to complete the drainage operation.

[0035] Example 2 See also Figures 1 to 6 A temporary drainage device for a transmission line, which includes a main body seat 1 and an operating rod 2, a fixed block 5 is provided in the middle of the main body seat 1, a first wire rack 3 is fixedly provided on the front side of the fixed block 5, a second wire rack 4 is fixedly provided on the rear side of the fixed block 5, an opening 6 is provided on the outside of the second wire rack 4, a wire clamping head 7 is movably provided on the upper side of the first wire rack 3, and a wire clamping head 7 is movably provided on the lower side of the second wire rack 4, an adjusting screw 8 is provided in the middle of the fixed block 5, a first collar 9 is screwed on the upper side of the adjusting screw 8, a second collar 10 is screwed on the lower side of the adjusting screw 8, the first collar 9 and the second collar 10 are fixedly connected to the collar 7 through a connecting rod 11, a collar 12 is fixed on the lower end of the adjusting screw 8, and a hook 13 is fixed on the upper end of the operating rod 2.

[0036] For better effect, the internal threads of the first sleeve ring 9 and the second sleeve ring 10 are in opposite directions. The adjusting screw 8 can simultaneously drive the first sleeve ring 9 and the second sleeve ring 10 to move closer to or away from each other.

[0037] For optimal results, a pre-clamping block 14 is installed within the first wire frame 3 and connected to the first wire frame 3 via a pre-clamping spring 15. This block 14 is used to pre-secure the drainage circuit. This block 14 provides a preliminary clamping effect on the inserted drainage circuit during the initial stage, stabilizing the circuit during the subsequent clamping process, reducing vibration, and preventing the drainage circuit from slipping or shifting during the clamping process.

[0038] For better effect, a stabilizing mechanism 16 is provided on the left and right sides of the main body seat 1. The stabilizing mechanism 16 includes a symmetrically arranged steering gear 17 and a wire seat 18. The steering gear 17 is connected to the fixed block 5 through a bearing. A driving rack 19 is meshed with the outer side of the steering gear 17. A driving spring 20 is provided between the upper side of the driving rack 19 and the fixed block 5. A steering arm 21 is fixedly provided on the outer side of the steering gear 17. The end of the steering arm 21 away from the steering gear 17 is connected to the wire seat 18.

[0039] For better effect, the wire seat 18 is hinged to the steering arm 21 via a rotating shaft. The wire seat 18 can slightly adjust the direction angle according to the position of the steering arm 21.

[0040] For better effect, a socket 22 is provided at the bottom of the fixing block 5 , and the position of the socket 22 corresponds to the position of the driving rack 19 .

[0041] To achieve optimal results, the operating lever 2 is provided with a grip 24 on its underside. An inner shaft 23 is movably mounted within the grip 24. A push plate 25 is mounted on the upper end of the inner shaft 23. An insertion rod 26 is mounted on the upper end of the push plate 25. The position of the insertion rod 26 corresponds to the position of the insertion hole 22. The inner shaft 23 is movable within the grip 24, thereby driving the push plate 25 and the insertion rod 26 to move. When the hook 13 at the upper end of the operating lever 2 engages the collar 12 at the lower end of the adjustment screw 8, the insertion rod 26 on the push plate can be inserted into the insertion hole 22 by pushing the inner shaft 23.

[0042] When the present device is in use, further, the stabilizing mechanism is preferably used as follows: in the initial state, the driving spring 20 pushes the driving rack 19 downward, and the adjustment arm 21 and the wire seat 18 move in the direction close to the fixed block 5. When the stabilizing mechanism is used: before the main body seat 1 is connected and fixed to the main line, the hook 13 of the operating rod 2 is first connected to the ring 12 of the main body seat 1. The operator holds the handle 24 on the lower side of the operating rod 2 and pushes the inner shaft 23 upward. The upward movement of the inner shaft 23 drives the push plate 25 to move upward, and then the insertion rod 26 on the push plate 25 moves upward. The insertion rod 26 can be accurately inserted into the socket 22 at the bottom of the fixed block 5. At this time, the insertion rod 26 and the driving rack 19 inside the fixed block 5 abut against each other. Pushing the inner shaft 23 upward again, the insertion rod 26 drives the drive rack 19 upward, compressing the drive spring 20. The drive rack 19 rotates the steering gear 17, causing the steering arm 21 and the wire holder 18 to move away from the fixed block 5. This facilitates the placement of the main body 1 outside the main line. Once the main body 1 is placed outside the main line, loosening the inner shaft 23 allows the steering arm 21 and the wire holder 18 to clamp and secure the main line. The two steering arms 21 are symmetrically arranged on the upper and lower sides of the main body 1, allowing the main line to be clamped and positioned from different directions, preventing the drainage device from being unstable during operation.

[0044] For better effect, the internal threads of the first sleeve ring 9 and the second sleeve ring 10 are in opposite directions. The adjusting screw 8 can simultaneously drive the first sleeve ring 9 and the second sleeve ring 10 to move closer to or away from each other.

[0045] For optimal results, a pre-clamping block 14 is installed within the first wire frame 3 and connected to the first wire frame 3 via a pre-clamping spring 15. This block 14 is used to pre-secure the drainage circuit. This block 14 provides a preliminary clamping effect on the inserted drainage circuit during the initial stage, stabilizing the circuit during the subsequent clamping process, reducing vibration, and preventing the drainage circuit from slipping or shifting during the clamping process.

[0046] For better effect, a stabilizing mechanism 16 is provided on the left and right sides of the main body seat 1. The stabilizing mechanism 16 includes a symmetrically arranged steering gear 17 and a wire seat 18. The steering gear 17 is connected to the fixed block 5 through a bearing. A driving rack 19 is meshed with the outer side of the steering gear 17. A driving spring 20 is provided between the upper side of the driving rack 19 and the fixed block 5. A steering arm 21 is fixedly provided on the outer side of the steering gear 17. The end of the steering arm 21 away from the steering gear 17 is connected to the wire seat 18.

[0047] For better effect, the wire seat 18 is hinged to the steering arm 21 via a rotating shaft. The wire seat 18 can slightly adjust the direction angle according to the position of the steering arm 21.

[0048] For better effect, a socket 22 is provided at the bottom of the fixing block 5 , and the position of the socket 22 corresponds to the position of the driving rack 19 .

[0049] To achieve optimal results, the operating lever 2 is provided with a grip 24 on its underside. An inner shaft 23 is movably mounted within the grip 24. A push plate 25 is mounted on the upper end of the inner shaft 23. An insertion rod 26 is mounted on the upper end of the push plate 25. The position of the insertion rod 26 corresponds to the position of the insertion hole 22. The inner shaft 23 is movable within the grip 24, thereby driving the push plate 25 and the insertion rod 26 to move. When the hook 13 at the upper end of the operating lever 2 engages the collar 12 at the lower end of the adjustment screw 8, the insertion rod 26 on the push plate can be inserted into the insertion hole 22 by pushing the inner shaft 23.

[0050] For better effect, a clamping mechanism 27 is provided inside the wire seat 18, and the clamping mechanism 27 includes a base plate 28, and side rods 29 are fixedly provided on the front and rear sides of the base plate 28. The end of the side rod 29 is hingedly provided with a hinge ring 30, and a driving rod 32 is provided on the side of the hinge ring 30 close to the base plate 28, and a clamping arm 33 is provided on the side of the hinge ring 30 away from the base plate 28. A pressure plate 31 is provided on the outside of the base plate 28, and the pressure plate 31 and the driving rod 32 are clamped with each other.

[0051] For better effect, a spring piece 34 is provided between the pressing plate 31 and the bottom plate 28, and the spring piece 34 is clamped with the bottom plate 28 through a slider 35. The spring piece 34 is clamped with the bottom plate 28 through the slider 35, so that the pressing plate 31 can move within a certain range, and the spring piece 34 provides elastic force.

[0052] For better effect, the driving rod 32 is provided with a limit groove 36, and the end of the pressing plate 31 is provided with a limit block 37. The limit groove 36 inside the driving rod 32 and the limit block 37 at the end of the pressing plate 31 cooperate with each other to prevent the driving rod 32 from excessive displacement during movement.

[0053] When the present device is in use, further, the clamping mechanism is preferably used as follows: the direction-adjusting arm 21 drives the wire holder 18 to approach the main line that needs drainage, and the main line is placed in the wire holder 18 and located between the opened clamping arms 33. At this time, the direction-adjusting arm 21 continues to drive the wire holder 18 to approach the main line, and the main line squeezes the pressure plate 31. The pressure plate 31 approaches the bottom plate 28, driving the spring piece 34 to compress. At the same time, the pressure plate 31 moves in the limit groove 36 inside the drive rod 32 through the limit block 37. Under the action of the hinge ring 30, the drive rod 32 drives the clamping arm 33 to approach the main line and further clamp the main line. This prevents the drainage device from flipping over, falling, etc.

[0054] Through the coordinated work of multiple mechanisms, this device can achieve stable clamping and temporary diversion operations on transmission lines, effectively improving the efficiency, stability and reliability of temporary diversion operations on transmission lines, and meeting the needs of transmission line maintenance and emergency repairs.
