Description

Technical Field

[0001] The invention relates to the field of electric power technology, in particular to a single-phase grounding line selection intelligent control device. Background Art

[0002] The microcomputer grounding line selection device is a protection device used in the power system. It is mainly used to detect and select the appropriate grounding line when a grounding fault occurs in the power system to achieve timely grounding and protection of the fault current. The device is usually composed of a microprocessor and related sensors. It can monitor the current, voltage and other parameters in the power system in real time, and select the grounding line according to the preset strategy, so as to quickly and accurately ground the fault point;

[0003] The microcomputer grounding line selection device can ensure the safe operation of the power system, prevent the expansion of power grid faults, and reduce the impact of accidents on equipment and personal safety. When the microcomputer grounding line selection device is in operation, it is first necessary to control the grounding line to complete the grounding action to provide assistance for subsequent line selection operations.

[0004] A DC system microcomputer grounding line selection device and its use method are disclosed in the patent application with reference publication number CN118348454A. The grounding line selection device operates the screw rod to move down and press the piston rod, and at the same time presses down the spring. Then, after the piston rod is compressed to the end of the stroke, it will drive the pointed cone to move down into the soil, so that the grounding wire is successfully grounded, and after the subsequent line selection is completed, the pointed cone can be driven out of the ground, achieving the effect of driving the ground line into the ground when it needs to be grounded, and automatically pulling it out when it does not need to be grounded.

[0005] The above-mentioned grounding line selection device uses a pointed cone inserted into the soil to complete the grounding action, and can perform grounding operations, but the insertion distance of the pointed cone is relatively limited, which is very likely to cause grounding instability and errors, and easily interfere with the operation of the line selection device, posing a large safety hazard. In addition, the grounding line selection device only uses a single pointed cone to complete the grounding action. When a grounding fault or error occurs, a safety accident is very likely to occur, posing a large safety risk.

[0006] At the same time, when the pointed cone is inserted and pulled out once, a large amount of mud will remain on the pointed cone. It is difficult to clean it thoroughly by just shaking it slightly, which can easily affect the subsequent grounding action and increase the difficulty of subsequent maintenance.

The multi-point grounding mechanism is used to actively control the closing and opening of the No. 1 grounding ring 3 and the No. 2 grounding ring 4. The multi-point grounding mechanism is composed of a lifting component, two cleaning components and two grounding components. The lifting component is correspondingly installed on the top of the grounding box 1. The two cleaning components cooperate with the lifting component and actively clean the No. 2 grounding ring 4. The two grounding components cooperate with the lifting component and contact with the No. 2 grounding ring 4 to complete the grounding action. At the same time, protection mechanisms are added to the two grounding components, and the two protection mechanisms are respectively used to actively protect the two grounding components.

[0043] Among them, electrical components such as the electric cylinder 9 and the line selection control device 2 are connected to switches through wires, and the switches are electrically connected to the controller. The specific structure of the controller is not limited, and an absolute encoder is installed on the electric cylinder 9 for accurately positioning the electric cylinder 9.

[0044] Embodiment 2: Based on the multi-point grounding mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the multi-point grounding mechanism.

[0045] like Figure 5 and Fig.12As shown, the lifting assembly includes a mounting seat 8 that can be detachably mounted on the top of the grounding box 1, an electric cylinder 9 can be detachably mounted on the mounting seat 8, a power cylinder 10 is rotatably mounted on the lower surface of the mounting seat 8, a connecting ring 11 is rotatably sleeved on the outside of the power cylinder 10, a one-way bearing 12 is installed between the connecting ring 11 and the power cylinder 10, when the trigger rod 17 moves downward toward the vertical groove 152 in the spiral groove 151, a one-way locking transmission is completed, when the trigger rod 17 moves from the vertical groove 152 to the spiral groove 151, a one-way release rotation is completed, and no restriction is imposed, the power cylinder 10 is of a through-design, and the power cylinder 10 is concentrically arranged with the No. 1 grounding ring 3, a push rod 13 is concentrically installed in the power cylinder 10, the push rod 13 is detachably fixedly connected to the output end of the electric cylinder 9, and the push rod 13 is fixedly connected to the output end of the electric cylinder 9. A connecting seat 14 is rotatably installed at the bottom of 13, a track groove 15 is arranged on the inner wall of the power cylinder 10, a slide plate 16 is fixedly sleeved on the outside of the push rod 13, the slide plate 16 is slidably installed in the power cylinder 10, and a trigger rod 17 is detachably fixedly installed on one side of the slide plate 16, the front end of the trigger rod 17 is slidably inserted into the track groove 15, and the power cylinder 10 is driven to complete the rotation and descending action through the joint action of the track groove 15 and the trigger rod 17. The track groove 15 is composed of a spiral groove 151 and a vertical groove 152. The spiral groove 151 is spirally coiled and opened on the inner wall of the power cylinder 10, and the vertical groove 152 is opened on the inner wall of the power cylinder 10 and connected to the tail of the spiral groove 151, so that the trigger rod 17 can switch back and forth between the spiral groove 151 and the vertical groove 152;

[0046] It is worth noting that when the grounding operation is controlled, the electric cylinder 9 is started by providing a lifting assembly to push the push rod 13 and the slide plate 16 downward. Since the trigger rod 17 is connected to the track groove 15, the trigger rod 17 first contacts the spiral groove 151 during the downward movement of the push rod 13, and is guided by the spiral groove 151 to drive the power cylinder 10 to complete the rotation, thereby completing the triggering of the cleaning assembly. Subsequently, under the guidance of the vertical groove 152, the push rod 13 and the slide plate 16 move vertically downward, pushing the trigger arm 22 to complete the downward movement under the guidance of the slideway, completing the grounding triggering of the grounding assembly. Therefore, the cleaning assembly and the grounding assembly are respectively controlled by the lifting assembly, which reduces the control difficulty and the subsequent maintenance difficulty of the staff.

[0047] In the embodiment of the present invention, the two cleaning components each include a connecting arm 18 that is detachably fixedly mounted on one side of the connecting ring 11, a slideway is provided through the connecting arm 18, and two cleaning pieces 19 are slidably engaged on the second grounding ring 4, the two cleaning pieces 19 are respectively detachably fixedly connected to the connecting arm 18 of the cleaning component, the two cleaning pieces 19 are made of insulating material, an open area is provided through the middle position of the two cleaning pieces 19, the open area cooperates with the grounding component for guidance, scraping strips 20 are hidden and installed on both sides of the top of the cleaning piece 19, the scraping strip 20 contacts the second grounding ring 4 to complete the scraping and cleaning, and the scraping strip 20 is detachably fixedly connected to the cleaning piece 19 by bolts, a trigger piece 21 is detachably installed on one side of the top of the cleaning piece 19, and inclined surfaces 33 are provided on both sides of the top of the trigger piece 21;

[0048] It is worth noting that: when performing the cleaning action, by providing a cleaning component, when the push rod 13 moves downward, the one-way bearing 12 of the power cylinder 10 is locked, so that the connecting ring 11 and the connecting arm 18 rotate accordingly, so that the cleaning member 19 rotates on the No. 2 grounding ring 4, and the grounding component rotates with the connecting arm 18. At this time, the conductive seat 6 slides in the annular track 5 on the No. 1 grounding ring 3, and the surface of the No. 2 grounding ring 4 is cleaned by the scraper 20 provided on the cleaning member 19, so as to provide assistance for the subsequent grounding component without manual cleaning. When the electric cylinder 9 moves upward subsequently, the trigger rod 17 first moves upward in the vertical groove 152 so that the grounding component completes the upward reset, and then the trigger rod 17 rotates the power cylinder 10 again under the guidance of the spiral groove 151. Since the one-way bearing 12 is in an unlocked state at this time, the free rotation of the power cylinder 10 will not drive the cleaning component.

[0049] In the embodiment of the present invention, both grounding components include a trigger arm 22 installed on one side of the connecting seat 14, the trigger arm 22 is correspondingly slidably engaged in the slideway, and a grounding member 23 is installed on the trigger arm 22, the grounding member 23 is composed of a conductive sleeve 231, a conductive rod 232 and a conductive head 233, the top of the conductive sleeve 231 is detachably fixedly connected to the conductive seat 6, the conductive rod 232 is slidably engaged in the conductive sleeve 231, a conductive plate 234 is installed at the bottom of the conductive rod 232, and the conductive rod 232 is detachably fixedly connected to the trigger arm 22, the conductive head 233 is detachably installed at the bottom of the conductive plate 234, and the conductive action is completed by the contact between the conductive head 233 and the second grounding ring 4;

[0050] It is worth noting that: when grounding is performed, a grounding component is provided. When the electric cylinder 9 is driven downward, the track groove 15 guides the trigger arm 22 to move downward, and the trigger arm 22 pulls the conductive rod 232 to extend out of the conductive sleeve 231, so that the conductive head 233 contacts the No. 2 grounding ring 4 to complete the grounding operation. Since the conductive sleeve 231, the conductive seat 6, the conductive plate 234 and the conductive head 233 are all made of conductive materials, the No. 1 grounding ring 3 and the No. 2 grounding ring 4 are interconnected, and a stable multi-point grounding operation can be completed. During subsequent resetting, the conductive head 233 follows the conductive rod 232 to move upward and shrink in the conductive sleeve 231, and after the conductive head 233 contacts the No. 2 grounding ring 4, the power rod 25 pulls the No. 2 friction ring 26 and the No. 1 friction ring 24 friction contact, so that the connecting arm 18 is stable and will not rotate unexpectedly, ensuring the stability of the grounding state. After subsequent resetting, the power rod 25 pushes the second friction ring 26 to separate from the first friction ring 24 to complete unlocking. At the same time, a friction block 28 is hidden on the second friction ring 26. The friction block 28 is extended by the push spring 305 to pre-contact with the first friction ring 24 to complete preliminary fixation, which provides assistance for the contact between the first friction ring 24 and the second friction ring 26. At the same time, the friction block 28 is pressurized by the push spring 305, so that the friction block 28 carries pressure and contacts with the first friction ring 24, thereby improving the friction strength and providing active compensation for the wear of the friction block 28, so that the friction block 28 is in stable contact with the first friction ring 24.

[0051] Among them, a No. 1 friction ring 24 is commonly installed on the two connecting arms 18, and the No. 1 friction ring 24 is concentrically arranged with the power cylinder 10. Two power rods 25 are symmetrically installed on both sides of the connecting seat 14. The two power rods 25 slide through the No. 1 friction ring 24 correspondingly, and a No. 2 friction ring 26 is commonly installed on the top of the two power rods 25, which is concentrically arranged with the No. 1 friction ring 24. The No. 2 friction ring 26 is in friction contact with the No. 1 friction ring 24 to complete the position restriction of the cleaning component. When the conductive head 233 contacts the No. 2 grounding ring 4, the No. 1 friction ring 24 is in friction contact with the No. 2 friction ring 26. A plurality of sliding grooves 27 are arranged in a circular array on the No. 2 friction ring 26 toward the No. 1 friction ring 24. Friction blocks 28 are slidably engaged in the plurality of sliding grooves 27. The friction blocks 28 can extend out of the No. 2 friction ring 26 to pre-contact with the No. 1 friction ring 24, and strong springs 29 are installed between the friction blocks 28 and the sliding grooves 27.

[0052] Embodiment 3: Based on the protection mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the protection mechanism.

[0053] like Figures 12 to 15As shown, the two protection mechanisms include protection covers 30 that are slidably engaged on both sides of the conductive plate 234, a sliding area that cooperates with the protection covers 30 is provided on the conductive plate 234, and a storage area is provided on the opposite side of the two protection covers 30, and the storage area is used to store the conductive head 233, and the two protection covers 30 can be combined into a closed protection member, and a reset spring 31 is installed between the conductive plate 234 and the two protection covers 30 through a bracket, and a ramp 32 is installed on one side of the two protection covers 30, and the ramps 32 of the two protection covers 30 are respectively in contact with the inclined surfaces 33 of the trigger member 21, and the two protection covers 30 are driven away from each other through the inclined surfaces 33 to complete the opening action;

[0054] It is worth mentioning that: when protecting the grounding component, a protection mechanism is provided. Under normal circumstances, under the action of the two reset springs 31, the two protection covers 30 are pulled close to each other to complete the closure, thereby completing the covering and protection of the conductive head 233, avoiding interference from the external environment, and ensuring the subsequent stable grounding state. Subsequently, in the downward movement path of the grounding component driven by the electric cylinder 9, first, the inclined platforms 32 of the two protection covers 30 contact and squeeze the inclined surface 33 of the trigger member 21, pushing the two inclined platforms 32 and the protection covers 30 away from each other, exposing the conductive head 233, and in the subsequent downward movement, the conductive head 233 is driven to contact the No. 2 grounding ring 4. In the subsequent upward reset, the inclined platform 32 is separated from the inclined surface 33, and the reset spring 31 completes the reset of the protective cover 30 again. At the same time, the protective cover 30 is composed of a No. 1 cover body 301 and a No. 2 cover body 302, so After the protective cover 30 is separated from the conductive head 233, the second cover body 302 contacts the second grounding ring 4, and the second cover body 302 moves upward under the action of the downward pressure to compress the push spring 305, so that the protective cover 30 can flexibly avoid the conductive head 233, so that the second cover body 302 and the conductive head 233 can both be stably fitted with the second grounding ring 4, and when the second cover body 302 moves upward, the telescopic member 304 performs piston movement in the squeezing area 303, and the gas in the squeezing area 303 is sprayed onto the conductive head 233 through the exhaust pipe 35 and the spray chamber 36 to complete the cleaning. After the push spring 305 is reset, the external gas is introduced into the squeezing area 303 through the intake pipe 34 to complete the compensation. At the same time, the protective cover 30 can be set to a conductive material, so that the contact area between the grounding component and the second grounding ring 4 is increased, and a stable grounding state can be obtained;

[0055] In the embodiment of the present invention, the protective cover 30 is composed of a No. 1 cover body 301 and a No. 2 cover body 302. The No. 1 cover body 301 is correspondingly slidably engaged on the conductive plate 234, and the No. 2 cover body 302 is arranged at the bottom of the No. 1 cover body 301. An extrusion area 303 is opened in the No. 1 cover body 301. A telescopic member 304 is installed on the top of the No. 2 cover body 302.

[0056] The present invention provides a single-phase grounding line selection intelligent control device, and the specific working principle is as follows: first, the grounding box 1 is fixed in the working area, and the grounding electrode 7 on the grounding box 1 is correspondingly inserted into the ground to complete the grounding action, and then the line is connected to the first grounding ring 3, and the multi-point controlled grounding of the first grounding ring 3 and the second grounding ring 4 is completed through the multi-point grounding mechanism. The grounding action can be freely opened and closed according to work requirements, and the operation is flexible. At the same time, the multi-point contact method is adopted to increase the contact area, avoid the problem of unstable grounding, and improve the safety of operation;

[0057] At the same time, during the grounding action, the multi-point grounding mechanism first drives the cleaning component to complete the cleaning action in a rotating manner, and then operates the grounding component to complete the grounding, which reduces the control difficulty and can complete the preparation work before grounding, ensuring the stable contact between the No. 2 grounding ring 4 and the grounding component. Under the cooperation of the lifting component, the cleaning component and the grounding component, during a single grounding process, the lifting component transmits the rotating power to the cleaning component, driving it to complete the cleaning work on the No. 2 grounding ring 4, which is beneficial to the subsequent grounding use and avoids the problem of dust on the No. 2 grounding ring 4 that affects the grounding effect. Subsequently, the lifting component transmits the downward movement amount to the grounding component, so that the grounding component completes a stable multi-point grounding action between the No. 1 grounding ring 3 and the No. 2 grounding ring 4, and runs smoothly. With the assistance of the protection mechanism, the protection mechanism can complete the closed protection of the conductive head 233 to avoid the problem of interference with the conductive head 233 caused by the external environment. In the grounding action, the protection mechanism completes the follow-up opening, so that the conductive head 233 completes the stable grounding work, making the overall operation of the equipment stable, reducing the maintenance difficulty, and providing a guarantee for power safety work.
