Description

Technical Field

[0001] This invention relates to the field of grounding device technology, specifically a split-type grounding device. Background Technology

[0002] In power systems, electrical equipment installations, and various scenarios requiring static electricity and lightning protection, grounding devices are core components ensuring safe equipment operation and preventing electric shock accidents. Their main function is to quickly and stably conduct static electricity, fault currents, or lightning currents generated by the equipment being discharged into the ground, forming a safe discharge channel and preventing current accumulation that could lead to equipment damage, fires, or even personal injury. Currently, split-type grounding devices are widely used in various industrial settings, power facilities, and civil electrical equipment. Their split structure facilitates transportation and installation, gradually replacing traditional integrated grounding devices and becoming one of the mainstream grounding equipment types.

[0003] Most existing grounding devices adopt an integrated structure or a relatively simple connection method. Common designs usually include threaded structures or direct welding. However, their wiring port structures are simple and often can only be adapted to connectors of specific sizes. When dealing with equipment of different models and interface standards, their versatility is poor, often requiring additional adapters or on-site modifications, which increases construction complexity and material costs.

Slider 3 is threadedly connected to the outer wall of both lead screw 2 and lead screw 3. Clamping plate 2 is fixedly connected to the outer wall of slider 3. The outer wall of clamping plate 2 can fit against the outer wall of wiring 2.

[0011] Preferably, the inner wall of the slider three is slidably connected to the slide rod two, the outer wall of the slide rod two is fixedly connected to the inner wall of the lower housing, and the outer walls of both the lead screw two and the lead screw three are rotatably connected to the fixing plate one, the outer wall of the fixing plate one is fixedly connected to the inner wall of the lower housing.

[0012] Preferably, the threads of lead screw two and lead screw three are arranged in opposite directions, and the outer walls of lead screw two and lead screw three are provided with a synchronous transmission structure.

[0013] Preferably, bevel gear 1 is fixedly connected to the outer walls of both lead screw 2 and lead screw 3, bevel gear 2 is meshed with the tooth end of bevel gear 1, fixed plate 2 is rotatably connected to the outer wall of bevel gear 2, fixed plate 2 is fixedly connected to the inner wall of the lower housing, threaded rod is threaded to the inside of bevel gear 2, insertion rod is fixedly connected to the bottom end of threaded rod, and insertion rod is slidably connected to the inside of the lower housing.

[0015] This invention provides a split-type grounding device. It has the following advantages: 1. The female end of this invention adopts a unique variable cross-section structure. Rotating the lead screw drives the slider and linkage mechanism, causing the clamping plates on both sides to move synchronously, thereby automatically clamping or releasing the wire inserted into the female end. It can flexibly adapt to wire connectors of different specifications and sizes, significantly improving the versatility of the device; it not only ensures a firm fixation of the wire but also makes the operation simple and efficient, reducing manual adjustment time.

[0016] 2. When the clamping plate is opened, the dustproof plate moves synchronously with the slider two, opening the female end interface for easy wiring insertion; when the wiring is pulled out, the dustproof plate automatically resets and seals the female end interface, which can effectively prevent external dust, rainwater, and debris from entering the female end, avoid interface blockage or corrosion, ensure the docking accuracy and conductivity of the female end and connector, and extend the service life of the female end.

[0017] 3. This invention connects lead screws two and three with opposite thread directions via a synchronous transmission structure. This ensures that during rotation, the sliders three on both sides drive the clamping plates two to move synchronously in opposite directions, thereby evenly and stably clamping and fixing the wiring two, preventing it from shaking. The rotation of lead screws two and three is converted into the vertical linear motion of the threaded rods through a bevel gear set, thereby driving the insertion rod to insert into the ground. This innovative integration of the wiring clamping function and the device's own fixing function into a single operation simplifies the installation process and enhances the overall anti-displacement capability of the device.

[0018] 4. This invention adopts a sliding adjustable structure for the top cover and the lower housing, combined with the fixing effect of the limiting hole and the limiting pin, to realize flexible adjustment of the overall height of the device. The relative height of the top cover and the lower housing can be flexibly adjusted according to different wiring lengths and different needs of the on-site installation scenario, which greatly improves the adaptability of the device to the scenario. At the same time, the sliding structure makes it easy for staff to disassemble the top cover and inspect and maintain the internal components, reducing maintenance costs. Attached Figure Description

[0021] The technical solution of the present invention will now be clearly and completely described 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.

[0022] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a split-type grounding device, including a top cover 1, a lower housing 2, a first wiring 3, and a second wiring 4. The top end of the second wiring 4 is fixedly connected to a female end 401, the interior of which has a variable cross-section. The bottom connector of the first wiring 3 can be inserted into the interior of the female end 401. The bottom end of the second wiring 4 is fixedly connected to a grounding grid structure 5. The interior of the lower housing 2 is penetrated and rotatably connected to a lead screw 6. The outer wall of the lead screw 6 is threadedly connected to a slider 7. Both sides of the slider 7 are rotatably connected to connecting rods 9. The outer wall of the connecting rods 9 is rotatably connected to a second slider 10. The interior of the second slider 10 is fixedly connected to a sliding rod 11. The outer wall of the sliding rod 11 is fixedly connected to a clamping plate 12. An observation window is provided on the exterior of the lower housing 2.

[0023] Specifically, the top of connector 2 4 is fixedly connected to a female terminal 401. The female terminal 401 has a variable cross-section structure design, which can adapt to connectors of different specifications and sizes. The bottom connector of connector 1 3 can be precisely inserted into the interior of the female terminal 401, realizing the detachable connection between connector 1 3 and connector 2 4. The bottom of connector 2 4 is fixedly connected to a grounding grid structure 5, which is used to conduct the current of the equipment to be discharged into the ground to achieve safe grounding. The interior of the lower housing 2 is rotatably connected to a lead screw 1 6. The outer wall of the lead screw 1 6 is connected to a slider 1 7 through a threaded connection. Both sides of the slider 1 7 are rotatably connected to connecting rods 9 through rotating shafts. The outer wall of the connecting rod 9 away from the slider 1 7 is rotatably connected to a slider 2 10. The outer wall of the sliding rod 11 near the connector 1 3 is fixedly connected to a clamping plate 12. The clamping plate 12 is used to clamp and fix connector 1 3 to ensure the stability of connector 1 3 after it is connected to the female terminal 401. The lower housing 2 has an observation window on its exterior, allowing staff to visually inspect the internal wiring connections, clamping status, and operational status of each component without disassembling the device. In use, wire 3 connects to external equipment requiring discharge. The bottom of wire 3 has a connector adapted to the female terminal 401. The variable cross-section design of the female terminal 401 allows for flexible connection to different types of equipment, enhancing the device's versatility. Rotating the lead screw 6 causes the slider 7 to slide axially along the lead screw 6. During this movement, the slider 7 pushes the corresponding slider 10 along the extension direction of the sliding rod 11 via the connecting rods 9 on both sides. The slider 10 then moves the clamping plates 12 on both sides towards the center via the sliding rod 11, firmly clamping the wire 3 inserted into the female terminal 401, thus achieving a stable connection between wire 3 and wire 4. This application first fixes the second wiring 4 to the grounding grid structure 5, then completes the assembly and fixation of the top cover 1 and the lower shell 2. After the foundation fixing work is completed, the wiring 3 is then connected. The wiring 3 is inserted into the interior through the reserved interface between the top cover 1 and the lower shell 2, and the wiring connection is completed by the clamping action of the clamping plate 12. The top cover 1 and the lower shell 2 not only protect the internal wiring connectors, female terminals 401, clamping plate 12 and other core components, preventing external dust, rainwater, debris and other substances from corroding the components and affecting their performance, but also form an isolation protection during wiring connection and equipment operation, preventing workers from accidentally contacting live parts and ensuring the personal safety of operators.

[0024] The grounding grid structure 5 includes a horizontal split 501, which is fixedly connected to the bottom end of the second terminal 4, and a vertical split 502 is fixedly connected to the outer wall of the horizontal split 501.

[0025] Specifically, the horizontal split element 501 is connected to the bottom of terminal 2 4 by welding or bolting to ensure the connection strength and conductivity between the horizontal split element 501 and terminal 2 4, avoiding poor contact that could lead to incomplete discharge. Vertical split elements 502 are uniformly fixed to the outer wall of the horizontal split element 501, and are arranged perpendicularly to the horizontal split element 501, forming a mesh structure. Both the horizontal split element 501 and the vertical split element 502 are made of metals with excellent conductivity, such as galvanized steel or copper, which ensures rapid current conduction and improves the corrosion resistance of the grounding grid structure 5, extending the service life of the device. During use, the entire grounding grid structure 5 must be completely buried underground, with the horizontal split element 501 laid horizontally underground and the vertical split element 502 inserted deep into the soil vertically underground. By increasing the contact area between the grounding grid structure 5 and the soil, the diffusion speed of the current from the equipment to be discharged into the ground is accelerated, reducing the grounding resistance.

[0026] The slider 7 is slidably connected to a slide rod 8. The outer wall of the slide rod 8 is fixedly connected to the inside of the lower housing 2. The outer wall of the slide rod 11 is slidably connected to the inside of the lower housing 2. The lower housing 2 is fixedly connected to a fixing sleeve 13. The inner wall of the fixing sleeve 13 is slidably connected to the outer wall of the slide rod 11.

[0027] Specifically, the two ends of the slide bar 8 are fixedly connected to the inner walls of the lower housing 2, and the slide bar 8 and the lead screw 6 are arranged parallel to each other. The core function of the slide bar 8 is to support and guide the slider 7. When the lead screw 6 rotates and drives the slider 7 to slide, the slide bar 8 can restrict the rotation trend of the slider 7, ensuring that the slider 7 can only slide in a straight line along the axis of the lead screw 6, avoiding the slider 7 from deviating or getting stuck, ensuring the smoothness of the slider 7's sliding process, and thus ensuring that the connecting rod 9 can stably push the slider 10 to move. The outer wall of the sliding rod 11 slides through the interior of the lower housing 2. The inner wall of the fixing sleeve 13 slides in conjunction with the outer wall of the sliding rod 11. The fixing sleeve 13 and the lower housing 2 are integrally formed or welded fixed structures. Its function is to provide auxiliary support and guidance for the sliding rod 11, further improve the stability of the sliding rod 11 when sliding, prevent the sliding rod 11 from bending or deviating during the movement, and ensure that the sliding rod 11 can drive the clamping plate 12 to move closer to the center or open to both sides, thus ensuring the clamping effect of the clamping plate 12 on the wire 3.

[0028] A connecting plate 14 is fixedly connected to the outer wall of the slider 10. A fixing rod 15 is fixedly connected to the outer wall of the connecting plate 14. A dustproof plate 16 is slidably connected to the outer wall of the fixing rod 15. The lower surface of the dustproof plate 16 can slide against the upper surface of the female end 401. One end of a spring 17 is fixedly connected to the outer wall of the dustproof plate 16. The other end of the spring 17 is fixedly connected to the outer wall of the connecting plate 14.

[0029] Specifically, a dustproof plate 16 is slidably fitted onto the outer wall of the fixing rod 15. The lower surface of the dustproof plate 16 can slide tightly against the upper surface of the female end 401, achieving full coverage protection for the upper surface of the female end 401. A spring 17 is fixedly connected between the outer wall of the dustproof plate 16 and the outer wall of the connecting plate 14. The spring 17 is fitted onto the outside of the fixing rod 15. In its natural state, the spring 17 can push the dustproof plate 16 to fit tightly against the upper surface of the female end 401, completely sealing the interface of the female end 401. When connector 3 needs to be inserted, first rotate screw 6 to slide slider 7 to both sides, causing clamping plate 12 to open to both sides. At this time, slider 2 10 will drive fixing rod 15 to move to both sides synchronously through connecting plate 14. Dustproof plate 16 moves to both sides with fixing rod 15, and the female terminal 401 interface is opened. When rotating screw 6 to slide clamping plate 12 to the middle to clamp connector 3, slider 2 10 moves to the middle, fixing rod 15 retracts into dustproof plate 16, and spring 17 is compressed. When connector 3 is pulled out, spring 17 returns to its natural state, pushing dustproof plate 16 to re-attach to the upper surface of female terminal 401, sealing the female terminal 401 interface, effectively reducing contamination of female terminal 401 interface, and ensuring the performance and service life of female terminal 401.

[0030] The outer wall of the wiring 13 is fitted with a flange 18 and a gasket 19. The lower surface of the gasket 19 is in contact with the upper surface of the top cover 1, and the lower surface of the flange 18 is in contact with the upper surface of the gasket 19. The flange 18 is bolted to the upper surface of the top cover 1.

[0031] Specifically, the sealing gasket 19 is made of an elastic sealing material, such as rubber or silicone, which has good sealing and insulation properties. The lower surface of the sealing gasket 19 is tightly fitted to the upper surface of the top cover 1, and the lower surface of the flange 18 is tightly fitted to the upper surface of the sealing gasket 19. The flange 18 is fixedly connected to the upper surface of the top cover 1 by multiple bolts, which are evenly distributed along the edge of the flange 18 to ensure a tight connection between the flange 18 and the top cover 1. Before inserting the connector 3 into the top cover 1, the flange 18 and the sealing gasket 19 must be sequentially fitted onto the outer wall of the connector 3 and their positions adjusted. After the connector 3 is inserted into the top cover 1 and the lower housing 2 and the clamping plate 12 is clamped and fixed, the flange 18 is then fixed to the top cover 1 with bolts. The core function of the sealing gasket 19 is to further enhance the sealing between the top cover 1 and the lower housing 2, preventing external rainwater, dust, etc. from entering the device through the gap between the top cover 1 and the wiring 3 and corroding the core components. The core function of the flange 18 is to assist the clamping plate 12 in fixing the wiring 3. Through the fixed connection between the flange 18 and the top cover 1, the upper part of the wiring 3 can be fixed. Together with the clamping plate 12, the lower part of the wiring 3 is clamped, achieving double fixation of the upper and lower ends of the wiring 3. This prevents the wiring 3 from shaking or loosening during use, ensures the connection stability between the wiring 3 and the female terminal 401, and further improves the overall sealing and protection performance of the device.

[0032] The lower housing 2 is rotatably connected to a second lead screw 20 and a third lead screw 21 on its lower side. One end of the third lead screw 21 extends out of the lower housing 2. The outer walls of the second lead screw 20 and the third lead screw 21 are threaded with a third slider 22. The outer wall of the third slider 22 is fixedly connected with a second clamping plate 24. The outer wall of the second clamping plate 24 can fit against the outer wall of the second connector 4.

[0033] Specifically, lead screw 20 and lead screw 31 are arranged parallel to each other and are installed at the same height, both located below clamping plate 12. One end of lead screw 31 penetrates the inner wall of the lower housing 2 and extends to the outside of the lower housing 2, forming an operating end. The operator can rotate lead screw 31 by rotating the operating end of lead screw 31, and the operation can be completed without disassembling the device. Each lead screw is connected to a corresponding slider 32. The inner wall of clamping plate 24 is provided with anti-slip texture to increase the friction between clamping plate 24 and the outer wall of wire 2 4, thereby improving the clamping effect. The outer wall of clamping plate 24 can fit tightly against the outer wall of wire 2 4. When lead screw 20 and lead screw 31 rotate, they will drive the corresponding slider 32 to slide along the axis of the lead screw, thereby driving clamping plate 24 to move closer to or away from wire 2 4. The worker rotates lead screw 3 21, which drives lead screw 2 20 to rotate synchronously, causing sliders 3 22 on both sides to slide in the opposite direction towards the middle. Slider 3 22 drives clamping plate 2 24 to move closer to the middle, thus clamping and fixing wire 2 4.

[0034] The inner wall of the slider 22 is slidably connected to the slide rod 23, and the outer wall of the slide rod 23 is fixedly connected to the inner wall of the lower housing 2. The outer walls of the lead screw 20 and the lead screw 3 21 are rotatably connected to the fixing plate 25, and the outer wall of the fixing plate 25 is fixedly connected to the inner wall of the lower housing 2.

[0035] Specifically, the core function of slide bar 23 is to support and guide slider 3 22. When lead screws 20 and 31 rotate, causing slider 3 22 to slide, slide bar 23 restricts the rotation trend of slider 3 22, ensuring that slider 3 22 can only slide linearly along the axis of the lead screw, avoiding deviation or jamming of slider 3 22, and ensuring the smoothness of slider 3 22's sliding process. This, in turn, ensures that clamping plate 24 can accurately and stably clamp wire 3. The outer wall of fixing plate 25 is fixedly connected to the inner wall of lower housing 2 by bolts or welding. Fixing plate 25 is connected to lead screws 20 and 31 by bearings, which can not only provide stable support for lead screws 20 and 31, ensuring their smooth rotation, but also reduce the friction generated during lead screw rotation, reduce component wear, extend the service life of the lead screw, and prevent deviation during lead screw rotation, ensuring the thread fit accuracy between the lead screw and slider 3 22.

[0036] The threads of lead screw 20 and lead screw 3 are arranged in opposite directions, and the outer walls of lead screw 20 and lead screw 3 are provided with synchronous transmission structure 26.

[0037] Specifically, in order to achieve synchronous rotation of lead screw 20 and lead screw 31 and ensure that the sliders 32 on both sides can move synchronously in opposite directions, the threads of lead screw 20 and lead screw 31 are set in opposite directions, that is, the thread direction of lead screw 20 is opposite to that of lead screw 31. When the two rotate synchronously, the sliders 32 on both sides will move in opposite directions, driving the clamping plate 24 to move towards or in opposite directions, thereby achieving clamping or releasing of the connecting line 24. Synchronous transmission structure 26 is provided on the outer wall of lead screw 20 and lead screw 3 21. This synchronous transmission structure 26 can adopt synchronous chain and sprocket transmission or synchronous gear transmission. In the synchronous chain and sprocket transmission method, the sprockets on lead screw 20 and lead screw 3 21 are connected by a chain. When lead screw 3 21 is rotated, the sprockets will drive lead screw 20 to rotate synchronously through the chain. In the synchronous gear transmission method, two meshing gears are fixed to the ends of lead screw 20 and lead screw 3 21 respectively. When lead screw 3 21 is rotated, the gears mesh and drive lead screw 20 to rotate synchronously. The synchronous transmission structure 26 ensures the synchronicity of the rotation of lead screw 20 and lead screw 3 21, avoiding asynchronous movement of slider 3 22 due to inconsistent rotation speeds, thereby ensuring uniform clamping force of clamping plate 24 to line 1 3 and improving the clamping effect.

[0038] Both lead screw 20 and lead screw 3 are fixedly connected to the outer walls of bevel gear 27. The tooth ends of bevel gear 27 are meshed with bevel gear 28. The outer wall of bevel gear 28 is rotatably connected to fixing plate 31. The outer wall of fixing plate 31 is fixedly connected to the inner wall of the lower housing 2. The internal thread of bevel gear 28 is connected to threaded rod 29. The bottom end of threaded rod 29 is fixedly connected to insertion rod 30. Insertion rod 30 is slidably connected inside the lower housing 2.

[0039] Specifically, to secure the lower housing 2 and prevent shaking or displacement during use, bevel gears 27 are fixedly connected to the outer walls of lead screws 20 and 21. The teeth of bevel gear 27 mesh with the teeth of bevel gear 28, forming a bevel gear transmission mechanism. This mechanism can change the direction of power transmission, converting the horizontal rotation of lead screws 20 and 21 into the vertical rotation of bevel gear 28. A fixing plate 31 is rotatably connected to the outer wall of bevel gear 28 via bearings. The outer wall of fixing plate 31 is fixedly connected to the inner wall of the lower housing 2, providing support and limiting for bevel gear 28, preventing it from shifting or shaking during rotation and ensuring stable rotation. A threaded rod 29 is threaded through and connected to the inside of bevel gear 28. A insertion rod 30 is fixedly connected to the bottom end of threaded rod 29, sliding through the bottom of the lower housing 2 and capable of sliding up and down vertically. When the operator rotates lead screw 21, causing lead screw 20 to rotate synchronously, lead screw 20 and lead screw 21 will respectively drive the corresponding bevel gear 27 to rotate. Bevel gear 27 meshes and drives bevel gear 28 to rotate. During the rotation of bevel gear 28, it will push threaded rod 29 to descend vertically through threaded engagement. Threaded rod 29 will then drive insertion rod 30 to descend synchronously and insert into the underground soil, thereby firmly fixing the lower housing 2 to the ground. This makes wiring 2 4, lower housing 2, and insertion rod 30 form an integral fixed structure, further improving the stability of the device, preventing loose wiring due to device shaking, and ensuring a safe and stable grounding discharge process.

[0040] The outer wall of the lower housing 2 is slidably connected to the inner wall of the top cover 1. A limiting hole 32 is provided on the outer wall of the lower housing 2. A limiting pin 33 is threadedly connected to the inside of the lower housing 2. The limiting pin 33 passes through the top cover 1 and is connected to the inside of the limiting hole 32.

[0041] Specifically, to accommodate wiring 3 of different lengths and facilitate installation and maintenance, the top cover 1 and the lower housing 2 adopt a sliding adjustment structure. The outer wall of the lower housing 2 slides against the inner wall of the top cover 1, allowing the lower housing 2 to slide up and down along the inner wall of the top cover 1, thereby adjusting the overall height of the top cover 1 and the lower housing 2 to accommodate wiring 3 with different insertion depths. Multiple limiting holes 32 are evenly distributed on the outer wall of the lower housing 2, arranged axially along the lower housing 2. A limiting pin 33 is threaded into the interior of the lower housing 2, penetrating the side wall of the top cover 1 and inserting into the corresponding limiting hole 32, thus fixing the top cover 1 and the lower housing 2. When the height of the top cover 1 and the lower housing 2 needs to be adjusted, the operator loosens the limiting pin 33, disengaging it from the limiting hole 32, then pushes the lower housing 2 along the inner wall of the top cover 1 to the appropriate height, and then tightens the limiting pin 33, inserting it into the corresponding limiting hole 32, thus fixing the height of the top cover 1 and the lower housing 2. This adjustable structure makes the device more adaptable, meeting the installation needs of different scenarios, while also facilitating the inspection and maintenance of internal components by staff.

[0042] Furthermore, during long-term use of the device, threaded components such as lead screw 6, lead screw 20, lead screw 31, and limit pin 33 may loosen due to vibration, environmental factors, etc., thus affecting the stability and reliability of the device. To prevent thread loosening, this device can be reinforced using existing thread strengthening methods. Anti-loosening nuts can be used in conjunction with the device; these nuts, through a special structural design, generate a reverse restraint force after tightening, effectively preventing the nut from loosening. Alternatively, cotter pins can be used with slotted nuts, inserting the cotter pin into the pin holes of the nut and bolt to restrict the rotation of the nut, achieving thread reinforcement. Operators can select the appropriate thread strengthening method according to the actual usage scenario and requirements to ensure that all components of the device are securely connected and operate stably for a long period.
