Description

Technical Field

[0001] This invention belongs to the field of electric shock protection devices, specifically relating to an electric shock protection device for the construction of a high-voltage disconnect switch. Background Technology

[0002] When constructing around a high-voltage disconnect switch, the circuit must be disconnected to ensure construction safety and avoid dangerous situations caused by electric shock.

[0003] Patent publication number CN218549456U relates to a high-voltage power line safety protection device, which includes: a first side support frame, a second side support frame, a protective net, and a wire positioning device. The side support frames are disposed on the side of the power line; the protective net is connected to a frame composed of the first and second side support frames; one end of the wire positioning device is connected to the first and / or second side support frames. Because the protective net surrounds the power line, placing it within a protected space, construction workers working near the power line are kept at a safe distance, preventing electric shock accidents. Simultaneously, the wire positioning device ensures that the distance between the power line and the protective net remains within a predetermined safe range, preventing the distance from falling below the safe distance due to power line movement, thus better guaranteeing the electrical safety of construction workers and avoiding electric shock accidents.

[0004] In existing technologies, when constructing around high-voltage disconnect switches, the circuit needs to be disconnected in advance. However, after disconnection, residual charge may not be released in time, and the switch head may be difficult to fix after being lifted. Accidental contact could close the prematurely connected circuit, causing electric shock if workers accidentally touch it. Furthermore, when reclosing the switch after construction, a rough reclosing action could cause a violent metal impact on the switch head, triggering another discharge. The aforementioned patent uses a protective net surrounding the power line, placing it within a protective space. Therefore, construction workers approaching the power line are at a safe distance, preventing electric shock accidents. However, workers using long metal tools still face the risk of accidental contact with the power line and electric shock. Summary of the Invention

[0005] The purpose of this application is to provide a device to prevent electric shock during the construction of high-voltage disconnect switches, which aims to solve the problem that residual charge on the surface of high-voltage disconnect switches after the circuit is closed can easily cause electric shock.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This application provides a device for preventing electric shock during the construction of a high-voltage disconnect switch, comprising: a base and an insulating shell; the insulating shell is disposed on both sides of the base, and terminals are disposed inside the insulating shell, the terminals penetrating the surface of the insulating shell, a knife switch is rotatably mounted on one side of the terminal surface, the opening and closing control circuit of the knife switch is connected, an insulating frame is mounted on the surface of the insulating shell, the wiring terminal is mounted on the surface of the insulating frame, and a connecting ring is slidably mounted on the surface of the wiring terminal, the wiring terminal and the terminal being indirectly connected through the connecting ring.

[0007] In some embodiments, a protruding rod is mounted on the surface of the switch. When the switch is lifted, the rotation causes the protruding rod to rotate. A frame is sleeved on the surface of the protruding rod. When the protruding rod rotates, it pushes the frame to move upward. An inclined rod is mounted on the surface of the insulating shell. A slider is slidably mounted on the surface of the inclined rod. A trapezoidal plate is mounted on the top of the slider. The slider is slidably mounted on the surface of the frame. After the frame moves, it pushes the slider to slide upward along the inclined rod and pushes the trapezoidal plate to move. A lifting rod is mounted on the surface of the trapezoidal plate near the connecting ring. After the trapezoidal plate moves, it drives the lifting rod to move upward. After the lifting rod moves, it lifts the connecting ring upward, moving the connecting ring away from the terminal and disconnecting the connection between the wiring terminal and the terminal.

[0008] In some embodiments, the frame, slider, and lifting rod are all made of insulating material, so that the wiring terminal will not be connected to other components for conduction after the connection of the wiring terminal and the terminal is disconnected. A first spring is provided between the connecting ring and the wiring terminal, and the elastic force of the first spring causes the connecting ring to reset.

[0009] In some embodiments, clips are slidably mounted on the surface of the insulating shell on both sides of the terminal. The inner walls on both sides of the trapezoidal plate are set as inclined surfaces. When the trapezoidal plate moves upward, the inclined surfaces on both sides of the inner wall move upward to squeeze the clips, push the clips to move towards the terminal and clamp the terminal. A copper busbar is mounted on the surface of the base. The copper busbar is fixedly connected to the inclined rod. The copper busbar is grounded. The terminal is connected to the trapezoidal plate through the clips and communicates with the inclined rod.

[0010] In this way, by opening the switch to disconnect the terminal block and the wiring terminal, the circuit connected to the terminal block stops releasing charge to the terminal block after the circuit is cut off during construction. This prevents workers from accidentally entering a live area and getting electric shock when using long metal tools. The diagonal rod is connected to the grounded copper busbar to conduct the charge on the terminal surface to the ground, eliminating any residual charge on the terminal surface and preventing workers from accidentally touching it and getting electric shock. In some embodiments, abutment rings are fixedly installed on the inner walls of both sides of the trapezoidal plate. The inner wall shape of the abutment ring matches the surface shape of the clip. The abutment rings hold the clip in place, increasing the contact between the clip and the inner wall of the trapezoidal plate, improving the connectivity between the clip and the trapezoidal plate, and ensuring that the inclined rod effectively discharges the residual charge on the terminal surface.

[0011] In some embodiments, a rotating block is rotatably mounted on the inner wall of the trapezoidal plate near the abutment ring. The reaction force of the clamp also squeezes the rotating block, causing it to rotate. The bottom shape of the rotating block matches the surface shape of the clamp. When the clamp reaches the bottom of the rotating block, the rotating block bounces back to its original position under the elastic force of the torsion spring. After resetting, the bottom of the rotating block and the arc surface of the abutment ring are in contact with the surface of the clamp. A baffle is installed on the inner wall of the trapezoidal plate near the rotating block. The baffle is in contact with the rotating block, and the baffle limits the rotating block to only reset to a specific angle. Buttons are slidably mounted on both sides of the trapezoidal plate, and a protruding plate is installed on the top of the rotating block. By pinching the buttons on both sides, the buttons push the protruding plate to rotate, causing the rotating block to rotate again, thus releasing the engagement between the rotating block and the clamp, allowing the switch to reset.

[0012] In some embodiments, the surface of the rotating block is set as an inclined plane to ensure that the rotating block can be pushed to rotate when the clamp squeezes the rotating block. A torsion spring is provided between the rotating block and the trapezoidal plate, and the elastic force of the torsion spring causes the rotating block to reset. A second spring is provided between the button and the trapezoidal plate, and the elastic force of the second spring causes the button to reset.

[0013] In this way, the clamps fit together and lock in place, ensuring that the clamps can effectively discharge the residual charge on the terminal surface. They also allow the switch to automatically lock in place after it is opened, preventing it from resetting. This ensures that the circuit remains disconnected during construction and prevents accidental activation of the switch, thus reducing the risk of electric shock to workers who may accidentally turn on the circuit prematurely.

[0014] In some embodiments, the frame surface is provided with a cavity, and the slider surface is provided with an extension rod. The extension rod is slidably installed in the cavity. When the frame pushes the slider downward to reset, the extension rod retracts into the cavity. The cavity surface is provided with micropores, and the extension rod surface is provided with an opening. The extension rod compresses the gas inside the cavity. By releasing the compressed gas through the opening and micropores, the extension rod retracts into the cavity, completing the reset of the frame and slider. A stop is slidably installed on the inner wall of the extension rod near the opening. A long rod is installed on the surface of the stop. When the extension rod retracts, it drives the long rod to move. A connecting spring is provided between the two long rods. The reaction force of the connecting spring on the two long rods pushes the long rod to slide, causing the stop to close the opening.

[0015] This reduces the outward flow velocity of gas within the cavity, thereby applying additional resistance to the retraction of the extension rod. Consequently, the frame applies resistance to the switch during the switch reset process, causing the switch to reset slowly. This prevents the switch from engaging violently during closing, which could lead to severe mechanical impacts that could cause discharge or generate electrical sparks, further improving the safety of workers.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the wiring terminal and the terminal block are indirectly connected by a connecting ring. The connection between the wiring terminal and the terminal block is disconnected by opening the switch, ensuring that the circuit connected to the wiring terminal stops releasing charge to the terminal block after the circuit is cut off during construction. At the same time, the terminal block is connected to the trapezoidal plate by a clip, and then connected to the inclined rod. The inclined rod is connected to the grounded copper busbar, which conducts the charge on the surface of the terminal block to the ground, eliminating the residual charge on the surface of the terminal block and preventing workers from accidentally entering the live area and getting electric shock when using long metal tools.

[0017] This invention uses the bottom of the rotating block and the arc surface of the abutment ring to fit and lock the clip surface, ensuring that the clip can effectively conduct residual charge on the terminal surface. At the same time, it prevents the trapezoidal plate from resetting. Once the switch is opened, it will automatically lock, ensuring that the switch is in a continuously open state during construction. After the switch is opened, the buttons on both sides need to be pinched at the same time to reset it, avoiding accidental activation of the switch and premature closure. This also prevents workers from being electrocuted by accidentally activating the circuit prematurely.

[0018] This invention applies additional resistance to the retraction of the extension rod when the frame drives the slider to reset, thereby causing the frame to apply resistance to the switch during the switch reset process, so that the switch resets slowly. This avoids the violent mechanical impact caused by the switch closing action, which could lead to discharge and generate electric sparks, and further improves the safety of workers.

[0022] 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.

[0023] like Figure 1 - Figure 8 As shown, one embodiment of the present invention is: a power high-voltage disconnecting switch construction anti-electric shock device, comprising: a base 1 and an insulating shell 2; the insulating shell 2 is disposed on both sides of the base 1, and a terminal 3 is disposed inside the insulating shell 2, the terminal 3 penetrating the surface of the insulating shell 2, a switch 5 is rotatably mounted on the surface of one side of the terminal 3, the opening and closing control circuit of the switch 5 is connected, an insulating frame 6 is mounted on the surface of the insulating shell 2, a wiring terminal 4 is mounted on the surface of the insulating frame 6, a connecting ring 13 is slidably mounted on the surface of the wiring terminal 4, the wiring terminal 4 and the terminal 3 are indirectly connected through the connecting ring 13, and the connection between the wiring terminal 4 and the terminal 3 is disconnected by opening the switch 5.

[0024] A protruding rod 7 is mounted on the surface of the switch 5. When the switch 5 is lifted, it rotates, causing the protruding rod 7 to rotate. A frame 8 is sleeved on the surface of the protruding rod 7. When the protruding rod 7 rotates, it pushes the frame 8 to move upward. A diagonal rod 9 is mounted on the surface of the insulating shell 2. A slider 10 is slidably mounted on the surface of the diagonal rod 9. A trapezoidal plate 11 is mounted on the top of the slider 10. The slider 10 is also slidably mounted on the surface of the frame 8. After the frame 8 moves, it pushes the slider 10 to slide upward along the diagonal rod 9 and pushes the trapezoidal plate 11 to move. A lifting rod 12 is mounted on the surface of the trapezoidal plate 11 near the connecting ring 13. After the trapezoidal plate 11 moves, it drives the lifting rod 12 to move upward. After the lifting rod 12 moves, it lifts the connecting ring 13 upward, making the connecting ring 13 away from the terminal 3.

[0025] The frame 8, slider 10, and lifting rod 12 are all made of insulating material. After disconnecting the connection between the terminal 4 and the terminal 3, the terminal 4 will not be connected to other components for conduction. A first spring is provided between the connecting ring 13 and the terminal 4. The elastic force of the first spring causes the connecting ring 13 to reset.

[0026] The insulating shell 2 has clips 15 slidably mounted on both sides of the terminal 3. The inner walls of the trapezoidal plate 11 are set as inclined surfaces. When the trapezoidal plate 11 moves upward, the inclined surfaces on both sides of the inner wall move upward to squeeze the clips 15, push the clips 15 to move towards the terminal 3 and clamp the terminal 3. A copper busbar 14 is installed on the surface of the base 1. The copper busbar 14 is fixedly connected to the inclined rod 9 and grounded. The terminal 3 is connected to the trapezoidal plate 11 through the clips 15 and communicates with the inclined rod 9. The terminal 3 is connected to the grounded copper busbar 14 through the inclined rod 9, so that the surface charge of the terminal 3 is conducted to the ground.

[0027] In this embodiment, when workers need to perform construction work around the disconnector, the switch 5 needs to be raised to disconnect the current path and ensure safety during operation. Raising the switch 5 causes the convex rod 7 to rotate, pushing the frame 8 upwards. After the frame 8 moves, it pushes the slider 10 upwards along the inclined rod 9, and also pushes the trapezoidal plate 11 to move. The trapezoidal plate 11 then moves the lifting rod 12 upwards, lifting the connecting ring 13 upwards, moving it away from the terminal 3 and disconnecting the connection between the terminal 4 and the terminal 3. The terminal 4 and the terminal 3 are indirectly connected through the connecting ring 13. By opening the switch 5 to disconnect the connection between terminal 4 and terminal 3, it is ensured that the circuit connected to terminal 4 stops releasing charge to terminal 3 after the circuit is cut off during construction. This prevents workers from accidentally entering the live area and getting electric shock when using long metal tools. At the same time, when the trapezoidal plate 11 moves upward, the inclined surfaces on both sides of the inner wall move upward to squeeze the clamp 15, pushing the clamp 15 towards terminal 3 and clamping terminal 3. At this time, terminal 3 is connected to the inclined rod 9 through the connection between the clamp 15 and the trapezoidal plate 11. The inclined rod 9 is connected to the grounded copper busbar 14, which conducts the surface charge of terminal 3 to the ground, eliminating the residual current on the surface of terminal 3 and preventing workers from accidentally touching it and getting electric shock.

[0028] Please see Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, abutment rings 16 are fixedly installed on the inner walls of both sides of the trapezoidal plate 11. The inner wall shape of the abutment ring 16 matches the surface shape of the clip 15. The abutment ring 16 supports the clip 15 and improves the contact between the clip 15 and the inner wall of the trapezoidal plate 11.

[0029] A rotating block 17 is rotatably installed on the inner wall of the trapezoidal plate 11 near the abutment ring 16. The reaction force of the clamp 15 also squeezes the rotating block 17. After being squeezed, the rotating block 17 rotates. The bottom shape of the rotating block 17 matches the surface shape of the clamp 15. When the clamp 15 reaches the bottom of the rotating block 17, the rotating block 17 bounces up and resets under the elastic force of the torsion spring. After resetting, the bottom of the rotating block 17 and the arc surface of the abutment ring 16 fit with the surface of the clamp 15, and they fit together to lock the clamp 15. A baffle 18 is installed on the inner wall of the trapezoidal plate 11 near the rotating block 17. The baffle 18 fits with the rotating block 17. The limit of the baffle 18 makes the rotating block 17 reset only to a specific angle. Buttons 20 are slidably installed on both sides of the trapezoidal plate 11. A protruding plate 19 is installed on the top of the rotating block 17. When the buttons 20 on both sides are pinched, the buttons 20 push the protruding plate 19 to rotate, causing the rotating block 17 to rotate again, releasing the fit between the rotating block 17 and the clamp 15, so that the switch 5 can be reset.

[0030] The surface of the rotating block 17 is set as an inclined surface to ensure that the rotating block 17 can be pushed to rotate when the clamp 15 squeezes the rotating block 17. A torsion spring is provided between the rotating block 17 and the trapezoidal plate 11. The elastic force of the torsion spring causes the rotating block 17 to reset. A second spring is provided between the button 20 and the trapezoidal plate 11. The elastic force of the second spring causes the button 20 to reset.

[0031] In this embodiment, during operation: the trapezoidal plate 11 moves upward, pressing the clamp 15 along the inclined plane. Simultaneously, the reaction force of the clamp 15 also presses the rotating block 17. The rotating block 17 rotates after being pressed, allowing the clamp 15 to pass through it and reach its bottom. When the clamp 15 reaches the bottom of the rotating block 17, it stops pressing. At this point, the rotating block 17 springs back to its original position under the force of the torsion spring and is limited by the baffle 18 to return to its maximum ejection angle. After returning to its original position, the bottom of the rotating block 17 and the arc surface of the abutment ring 16 fit against the surface of the clamp 15, mutually engaging and securing the clamp 15. This ensures that the clamp 15 can effectively discharge residual charge from the surface of the terminal 3. By using the rotating block 17 to lock the clamp 15, the trapezoidal plate 11 cannot be reset. Once the switch 5 is opened, it will automatically lock, ensuring that the switch 5 remains open during construction. The switch 5 is difficult to close again after it is opened. Only by simultaneously squeezing the buttons 20 on both sides, the buttons 20 push the convex plate 19 to rotate, causing the rotating block 17 to rotate again, releasing the engagement between the rotating block 17 and the clamp 15, can the switch 5 be reset. If only one button 20 is squeezed while the rotating block 17 and the clamp 15 on the other side remain locked, the switch 5 still cannot be reset. This prevents accidental activation of the switch 5, which could cause it to close prematurely. This also prevents workers from being electrocuted by accidentally activating the circuit prematurely.

[0032] Please see Figure 1 - Figure 8In another embodiment of the present invention, based on the above embodiments, a cavity 21 is provided on the surface of the frame 8, and an extension rod 23 is provided on the surface of the slider 10. The extension rod 23 is slidably installed in the cavity 21. When the frame 8 pushes the slider 10 to reset downwards, the extension rod 23 retracts into the cavity 21. A micropore 22 is provided on the surface of the cavity 21, and an opening 24 is provided on the surface of the extension rod 23. The extension rod 23 compresses the gas inside the cavity 21. By releasing the compressed gas from the opening 24 and the micropore 22, the extension rod 23 retracts into the cavity 21, completing the reset of the frame 8 and the slider 10. A stop 25 is slidably installed on the inner wall of the extension rod 23 near the opening 24. A long rod 26 is installed on the surface of the stop 25. When the extension rod 23 retracts, it drives the long rod 26 to move. A connecting spring 27 is provided between the two long rods 26. The reaction force of the connecting spring 27 on the two long rods 26 pushes the long rod 26 to slide, causing the stop 25 to close the opening 24.

[0033] In this embodiment, when the gate 5 is reset, it pushes the frame 8 downward, and the frame 8 pushes the slider 10 downward to reset. At this time, the extension rod 23 retracts into the cavity 21. During the retraction of the extension rod 23 into the cavity 21, it compresses the gas inside the cavity 21. The compressed gas is released through the opening 24 and the micropore 22, allowing the extension rod 23 to retract into the cavity 21, completing the reset of the frame 8 and the slider 10. At the same time as the extension rod 23 retracts, it drives the long rod 26 to move. The two long rods 26 move closer to each other and compress the connecting spring 27. The connecting spring 27 compresses the two long rods 26. The reaction force of 6 pushes the long rod 26 to slide. After the long rod 26 slides, it drives the stop gate 25 to move. After the stop gate 25 moves, it blocks the opening 24. At this time, the compressed gas in the cavity 21 can only flow out through the micropore 22, reducing the speed at which the gas flows out of the cavity 21. This applies additional resistance to the retraction of the extension rod 23, so that the frame 8 applies resistance to the switch 5 during the reset process, causing the switch 5 to reset slowly. This avoids the switch 5 from being violently closed, causing a violent mechanical impact that could lead to discharge and generate electric sparks, and further improves the safety of the workers.
