Description

Technical Field

[0001] This invention belongs to the technical field of high-voltage grounding tools for pumped storage power stations, specifically relating to a Y-type push-type high-voltage grounding tool. Background Technology

[0002] Maintenance personnel are usually positioned below the high-voltage line, using a high-voltage line grounding tool to connect the grounding wire to the high-voltage line. Existing tools of this type are all side-mounted clamps, which make it difficult to determine whether the end of the clamp is on the same horizontal plane as the high-voltage line when operating below it. This leads to difficulties in aligning and connecting the clamp to the high-voltage line, requiring multiple attempts. Summary of the Invention

[0003] To address the difficulty in attaching existing high-voltage grounding wires, this invention provides a Y-type push-type high-voltage grounding wire tool, which effectively attaches the grounding wire by pushing the interface to the target high-voltage line.

[0004] The solution adopted by this invention to solve its technical problem is as follows: a Y-type push-type high-voltage grounding wire tool, comprising an insulating rod body, an insulating handle, and a grounding wire. A Y-shaped clamp is fixedly installed at the front end of the insulating rod body. The Y-shaped clamp includes a left fork and a right fork fixed on both sides of the end tube. Each left and right fork includes a fixed base and a fork portion. A hollow area is provided in the middle of the left and right forks, and a shaft hole is provided in the hollow area. An elastic flipping body is fitted in the hollow area. The elastic flipping body is provided with a pin, which is installed in the shaft hole, and a torsion spring is installed on the pin. A Y-shaped conductor is fitted in the end tube, and an elastic component is installed at the lower end of the Y-shaped conductor. An elastic pin assembly is installed on the right side of the end tube. The lower end of the Y-shaped conductor is located in the end tube and is fixedly connected to the end of the grounding wire. The elastic pin assembly is used to restrict the elastic flipping body from flipping outward, and the control end of the elastic pin assembly is located at the root of the insulating handle.

[0005] The elastic flipping body includes a V-shaped body, which includes a pressure arm and a limiting arm, the two having a certain acute angle, and a shaft hole is provided at the root of the V-shaped body and a pin is fixedly installed thereon.

[0006] The Y-type conductor consists of a V-shaped head and a sliding rod integrally formed. The sliding rod is located at the center of the bottom of the V-shaped head, and the V-shaped groove at the top of the V-shaped head is used to support the high-voltage line.

[0007] A spring seat is horizontally arranged inside the end tube, and a guide hole is provided in the center of the spring seat. The slide rod is fitted into the guide hole. At the same time, a thrust spring is fitted on the outside of the slide rod. A limit ring is provided at the bottom of the slide rod to prevent the slide rod from disengaging from the guide groove. A wiring groove is also provided at the bottom of the slide rod. The copper wire at the end of the grounding wire is pressed and fixed in the wiring groove by a pressure plate and a set screw.

[0008] A clearance groove is provided in the middle of one of the V-shaped heads, as shown in the figure. This clearance groove can prevent interference with the elastic flipping body.

[0009] A pin sheath is located on the outside of the fixed seat of the right fork. The pin sheath has an inner cavity in which a pin is fitted. A strip-shaped guide groove is provided on the side of the pin sheath. A limit block is fixed on one side of the pin and fits into the guide groove. A return spring is fitted at the bottom of the pin sheath, supporting the rear end of the pin and keeping it in a naturally upward position. A pull rope is fixed to the rear end of the pin. A rope sleeve is installed at the outer end of the pin sheath, and the pull rope is fitted inside the rope sleeve. A support is provided at the base of the insulated handle. The proximal end of the rope sleeve is supported on the support, and the proximal end of the pull rope is led out from the through hole of the support and connected to an insulated pull ring.

[0010] The pin is set as a wedge with an inclined inner wall, and the pressure arm of the elastic flipping body is set as a reverse wedge with an inclined outer wall.

[0011] The limiting block is connected by a connecting rod. A hook is set at the front end of the connecting rod and inserted into the through hole of the limiting block. By pulling the connecting rod at the rear end, the limiting block is driven to move backward, which in turn drives the pin to move backward.

[0012] The beneficial effects of this invention are as follows: When using this invention, simply pushing the tool forward achieves grounding with the high-voltage line. The grounded state features a self-locking function with a clamping effect, preventing it from falling off on its own. Furthermore, it can be easily removed by pulling the ring, making operation simple. Since the user is positioned below the high-voltage line, it is easy to aim at the line and push it out, based on the pole's axial direction of vision. The line is successfully attached on the first attempt, with virtually no deviation issues. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1: A kind of Figure 1 The Y-type push-type high-voltage grounding wire tool shown is designed to address the problem of difficulty in attaching existing high-voltage grounding wires. It aims to achieve rapid grounding by aiming and inserting the wire from below. Figure 1 The diagram shows an implementation method, which mainly consists of structural components such as an insulating rod body 1, an insulating handle 2, a Y-shaped clamp 3, an end tube 4, an elastic flipping body 5, an elastic pin assembly 6, a Y-shaped conductor 7, and a grounding wire 8.

[0026] Specifically, a Y-shaped clamp 3 is fixedly installed at the front end of the insulating rod 1, and an insulating handle 2 is fitted at the rear end of the insulating rod 1. Figures 2-4 It can be seen that the Y-shaped clamp 3 includes a left fork 31 and a right fork 32 fixed to both sides of the end tube 4. For example... Figure 6 and Figure 7 As shown, both the left fork 31 and the right fork 32 include a fixing base 34 and a fork portion. In this embodiment, the fork portions of the left fork 31 and the right fork 32 are arc-shaped. However, it is not excluded that each fork may be set as a flat plate. The left fork 31 and the right fork 32 are preferably made of high-temperature resistant engineering plastic material and are formed by mold injection molding.

[0027] from Figure 5 and Figure 7It can be seen that the right fork 32 is different from the left fork 31. Specifically, the right fork 32 has a hollow area 35 in the middle, and a shaft hole 36 is provided in the hollow area 35.

[0028] An elastic flipper 5 is fitted inside the hollowed-out area 35, such as... Figure 9 One implementation of the elastic flipper 5 shown includes a V-shaped body 52, which comprises a pressure arm 53 and a limiting arm 54, the two having a certain acute angle (it is possible that the angle is right or obtuse). A shaft hole is provided at the root of the V-shaped body 52, and a pin 51 is fixedly mounted thereon. Figure 5 As can be seen, after the pin 51 is fitted with the shaft hole 36, the elastic flipper 5 can flip within the hollow area 35. A torsion spring is installed on the pin, which ensures that the elastic flipper 5 is in the ideal initial position, for example... Figure 5 The position in the middle.

[0029] Figure 5 It can also be seen that a Y-shaped conductor 7 is installed inside the end tube 4, such as Figure 8 In this Y-type conductor 7, a V-shaped head 71 and a slide bar 72 are integrally formed copper conductors, with the slide bar 72 located at the center of the bottom of the V-shaped head 71. The V-shaped groove on the upper part of the V-shaped head 71 is used to support the high-voltage line. Figure 5 In the middle, a spring seat 41 is horizontally arranged inside the end tube 4. The center of the spring seat 41 has a guide hole. The slide rod 72 is fitted into the guide hole, and a thrust spring 76 is fitted on the outside of the slide rod 72. A limit ring 74 (which can be a nut or a snap ring) is provided at the bottom of the slide rod 72 to prevent the slide rod 72 from disengaging from the guide groove. A wiring groove 75 is also provided at the bottom of the slide rod 72. The copper wire at the end of the grounding wire 8 is pressed and fixed into the wiring groove 75 by a pressure plate and a set screw.

[0030] Additionally, a clearance groove 73 is provided in the middle of one page of the V-head 71, such as... Figure 8 As shown, the clearance groove 73 can avoid interference with the elastic flipper 5.

[0031] from Figure 2 and Figure 4 It can be seen that the width of the elastic flipper 5 is smaller than the width of the V-head 71, and the width of the V-head 71 is smaller than the width of the right fork 32 (located in the hollow area).

[0032] A spring-loaded component is installed at the lower end of the right fork 32, such as... Figure 5 and Figure 7As shown, an elastic pin assembly 6 is installed on the right side of the end tube 4. Specifically, a pin sheath 61 is located outside the fixing seat 34 of the right fork 32 (or integrated with the fixing seat). The pin sheath 61 has an inner cavity in which a pin body 62 is fitted. A strip-shaped guide groove 63 is provided on the side of the pin sheath 61. A limiting block 64 is fixed to one side of the pin body 62, and the limiting block 64 is fitted into the guide groove 63. A return spring 65 is fitted at the bottom of the pin sheath 61, supporting the rear end of the pin body 62 to maintain its natural upward position. A pull rope 66 is fixed to the rear end of the pin body 62, and a rope sleeve 67 is installed at the outer end of the pin sheath 61, with the pull rope 66 fitted into the rope sleeve 67. Figure 1 As shown, a support 68 is provided at the base of the insulating handle 2. The proximal end of the rope loop 67 is supported on this support 68, and the proximal end of the pull rope is led out from the through hole of the support and connected to an insulating pull ring 69. Thus, when the pull ring is pulled, the pin body can be moved backward via the pull rope; when the pull ring is released, the pin body moves forward to reset under the action of the return spring. Figure 5 As can be seen, when the pin is in the forward position, it can support the inside of the pressure arm 53, thereby preventing the V-shaped body 52 of the elastic flipping body 5 from flipping upward. Then, under the support of the V-shaped body 52, the Y-shaped conductor 7 presses the high-voltage wire onto the V-shaped body 52, and is in a pressed and locked state, ensuring good contact between the Y-shaped conductor 7 and the high-voltage wire.

[0033] In this embodiment, when using the device, hold the insulated handle 2 and push the Y-shaped clamp 3 parallel to the target high-voltage line, such as... Figure 10 middle As shown, after the Y-shaped clamp 3 is pushed further, the high-voltage line presses the elastic flipper 5 to make it rotate as shown. As shown, as the Y-shaped clamp 3 continues to be pushed, the high-voltage line compresses the Y-shaped conductor 7 and retracts it backward. As shown, arrow A indicates that the Y-shaped conductor 7 retracts backward. During this overshoot, the high-voltage line continues to press the elastic flipper 5 to continue flipping (the elastic flipper 5 is located in the relief groove of the Y-shaped conductor 7) until the elastic flipper completely detaches from the high-voltage line. Then, the elastic flipper 5 resets under the action of its own torsion spring and is locked under the action of the elastic pin assembly 6. Releasing the handle allows the Y-shaped conductor 7 to pop forward. Through the mutual pressing of the Y-shaped conductor 7 and the elastic flipper 5, the high-voltage line is ensured to have a tight contact effect within the Y-shaped conductor 7. As shown. When it is necessary to remove the tool, simply pull the pull ring 69 backward. The pull rope drives the pin 62 to move backward, thereby losing the locking of the elastic flipping body 5. Continue pulling the pull ring (or pull the handle). Under the action of downward pulling force and the tool's own weight, the tool will disengage from the high-voltage line, as shown. As shown in the figure, arrow B indicates that the elastic pin assembly 6 moves downward.

[0034] When using this device, simply push the tool forward to achieve grounding with the high-voltage line. The grounded state features a self-locking mechanism that prevents it from detaching on its own. Furthermore, it can be easily removed by pulling the ring, making operation simple. Since the user is positioned below the high-voltage line, it is easy to aim at the line and push it out, ensuring successful connection on the first attempt with minimal deviation.

[0035] Example 2: Based on Example 1, to ensure that the elastic flipper 5 remains outside the pin of the elastic pin assembly 6 when the wire returns, the pin 62 is configured as a wedge with an inclined inner wall, and the pressure arm 52 of the elastic flipper 5 is configured as a reverse wedge with an inclined outer wall. Thus, when the pressure arm 52 resets, it can cross the pin 62 under the action of its own torsion spring and be located outside the pin 62. Based on this structure, even if the pressure arm 52 is not located outside the pin 62, during the process of pushing and pressing the high-voltage wire, the high-voltage wire can compress the elastic flipper 5, causing its pressure arm 52 to swing and press the pin 62, placing it outside the pin.

[0036] Example 3: Based on Example 1, the limiting block 64 is connected by a connecting rod, that is, a hook is set at the front end of the connecting rod and inserted into the through hole of the limiting block 64. By pulling the connecting rod at the rear end, the limiting block is driven to move backward, thereby driving the pin 62 to move backward.

[0037] Example 4: Based on Example 1, guide grooves 33 are further provided on the inner sidewalls of the left fork 31 and the right fork 32, and the two sides of the V-shaped head 71 of the Y-shaped conductor 7 are respectively fitted into the corresponding guide grooves 33.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
