Description

Technical Field

[0001] The present invention relates to the technical field of grounding, and in particular to a fast grounding device for power grid operation and maintenance. Background Art

[0002] In the power system, especially in the maintenance, inspection, troubleshooting or emergency situations of high-voltage transmission lines and substations, it is necessary to quickly and reliably achieve temporary grounding through a grounding device, so as to quickly connect the electrical equipment or lines to the earth to ensure the safety of personnel and the normal operation of the equipment.

[0003] When using the maintenance quick grounding device, the grounding end is usually inserted directly into the ground. Although this method is simple and quick to operate, it is not strong enough and can easily come off due to loose soil or external force, thus causing safety hazards. In addition, it is difficult to insert when the soil is hard. In contrast, a reliable grounding device needs to be fixed by bolts, clips, etc. to ensure stability and easy insertion, but this will increase the complexity and time cost of operation when the soil is soft, and cannot meet the needs of quick grounding. In other words, the existing grounding device cannot adapt to the soft and hard geological conditions and take into account both stability and speed.

[0004] Based on the above situation, the present invention proposes a power grid operation and maintenance rapid grounding device. Summary of the invention

[0005] In order to overcome the shortcoming of being unable to adapt to the soft and hard conditions of the geology and take both stability and speed into consideration, the present invention provides a power grid operation and maintenance rapid grounding device.

[0006] The cam is provided with a plurality of sliding members, each of which is provided with a plurality of sliding members, each of which is provided with a plurality of sliding members, each of which is provided with a plurality of sliding members.

[0007] In a preferred embodiment of the present invention, it also includes a screw rod, which is slidably connected to the grounding frame, and a second sliding block symmetrically distributed along the grounding frame is slidably connected to a side of the grounding frame close to the screw rod, and a guide frame is slidably connected to the grounding frame, and the guide frame is rotationally connected to the screw rod. At least two clamping rods are slidably connected to the grounding frame, and the guide frame is used to push the clamping rod into the soil.

[0008] In a preferred embodiment of the present invention, the grounding frame is provided with a through hole for the clamping rod to pass through, and the guide frame is provided with an oblique groove slidably connected to the clamping rod.

[0009] In a preferred embodiment of the present invention, an internal thread is formed on a side of the second slider close to the screw rod, and when the symmetrically distributed second sliders contact each other, the second sliders engage with the external thread of the screw rod through the internal thread.

[0010] In a preferred embodiment of the present invention, it also includes a fixing rod, which is fixedly connected to the grounding frame. When the fixing rod rotates with the grounding frame, it does not contact the sliding rod. The fixing rod is slidably connected to a clamping block for clamping the ground coil. One side of the clamping block is provided with an arc surface, and the other side of the clamping block relative to the arc surface is provided with a straight surface, which is used to limit the ground coil to only rotate in one direction clockwise when it is clamped by the clamping block. A second spring is fixedly connected between the fixing rod and the clamping block.

[0011] In a preferred embodiment of the present invention, it further comprises a first guide block for releasing the locking of the ground coil by the locking block, and the first guide block is fixedly connected to the base.

[0012] In a preferred embodiment of the present invention, the first guide block is provided with an inclined surface, and the clamping block moves downward to contact the inclined surface of the first guide block.

[0013] In a preferred embodiment of the present invention, it also includes a second tension spring symmetrically distributed along the grounding frame, the second tension spring corresponds one-to-one with the second slider, one end of the second tension spring is fixedly connected to the grounding frame, and the other end is fixedly connected to the corresponding second slider, the base is fixedly connected to a second guide block symmetrically distributed along the grounding frame, the second guide block corresponds one-to-one with the second slider, the second guide block is used to push the symmetrically distributed second sliders closer to each other, and a third spring is fixedly connected between the guide frame and the grounding frame.

[0014] In a preferred embodiment of the present invention, the second guide block is provided with an inclined surface, and the second sliding block moves downward to contact the corresponding inclined surface of the second guide block.

[0015] In a preferred embodiment of the present invention, it also includes a card frame symmetrically distributed along the grounding frame, the card frame is slidably connected to the grounding frame, one end of the card frame is engaged with the ground coil, and the other end of the card frame is in contact with the screw rod, the screw rod is provided with a groove, the groove moves downward to align with the card frame, and a fourth spring is fixed between the card frame and the grounding frame.

[0016] The beneficial effect is that when the soil is soft, the present invention can quickly connect the grounding frame into the ground by first quickly pressing down and then screwing the grounding frame. When the soil is hard, the whole spiral grounding frame can be selected to achieve grounding. Moreover, through the action of the grounding frame and the sliding rod, the whole device is relatively stable and firm and will not fall over. It not only meets the function of rapid grounding, but also flexibly adapts to different geological environments and takes into account stability.

[0017] The present invention rotates the screw rod so that the guide frame squeezes the clamping rod through the oblique groove and moves obliquely upward, and the clamping rod moves out of the through hole of the grounding frame and is inserted into the soil like a "barb", so that the grounding frame is difficult to pull out and is more firmly inserted into the soil.

[0018] The present invention arranges components such as a clamping block and a first guide block, so that the ground wire will not be loose before the wiring frame is fully inserted and fixed. In this way, the user is forced to fully insert the grounding frame into the soil to ensure that the grounding frame reaches a sufficient depth, thereby improving the reliability and safety of grounding; at the same time, it is prevented from performing wiring operations when the grounding frame is not fully inserted, thereby ensuring the standardization of operations, preventing misoperation, and reducing safety hazards caused by poor grounding.

[0019] The present invention provides a third spring so that the clamping rod is difficult to be inserted into the soil before the grounding frame is firmly inserted into the ground, thereby avoiding premature operation of the screw rod, thereby preventing the clamping rod from being stuck on the soil surface or in the shallow soil in advance, making it difficult for the grounding frame to continue to be smoothly and quickly inserted to a predetermined depth.

[0020] When the device is removed, the third spring resets and drives the guide frame to rebound upward quickly at the moment the second slide block is disengaged from the second guide block, thereby driving the screw rod to move upward and reset, and at the same time, the clamping rod is automatically retracted into the grounding frame, and there is no need to reversely rotate the screw rod, thereby improving the convenience of operation.

[0021] The present invention forces the user to extend the card rod before wiring through the arrangement of the card frame and the fourth spring, thereby ensuring that the card rod can enhance stability and reliability and avoiding wiring operations when the card rod is not extended, thereby ensuring standardization of operations, preventing misoperation, and reducing safety hazards caused by poor grounding.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1: A fast grounding device for power grid operation and maintenance, such as Figure 1-Figure 3As shown, it includes a base 1, and four rivets are arranged at the bottom of the base 1. The base 1 is slidably connected to a slide bar 4 symmetrically distributed along the left and right sides of the base 1. The upper section of the slide bar 4 is a thin rod, and the lower section of the slide bar 4 is a thick rod. A grounding frame 2 is limitedly arranged between the slide bars 4 symmetrically distributed on the left and right sides. The lower part of the grounding frame 2 is provided with an external thread, and the upper part of the grounding frame 2 is provided with a groove symmetrical along the center of the grounding frame 2. The slide bar 4 is located in the corresponding groove. When the grounding frame 2 rotates counterclockwise, the slide bar 4 is squeezed out of the groove, and the upper part of the grounding frame 2 is rotatably connected to the ground coil 3. The slide bar 4 is fixedly connected to the base 1, and the base 1 is slidably connected to two first sliders 6 along the left and right directions. The first sliders 6 are provided with internal threads on the sides close to the grounding frame 2. When the grounding frame 2 squeezes the sliding rod 4 out of the groove, the two first sliders 6 contact each other. At this time, the internal threads of the first sliders 6 and the external threads of the grounding frame 2 are engaged with each other. The first slider 6 on the left side corresponds to the sliding rod 4 on the right side, and the first slider 6 on the right side corresponds to the sliding rod 4 on the left side. First tension springs 7 symmetrically distributed along the front and back of the first slider 6 are fixedly connected between the first slider 6 and the corresponding sliding rod 4.

[0035] First, press the base 1 downward so that the rivets of the base 1 are inserted into the ground, thereby making the entire grounding device firmly on the ground. At the same time, the base 1 can also press the soil around the grounding frame 2 to prevent the soil from loosening when the grounding frame 2 is inserted into the soil, causing the grounding frame 2 to tilt, thereby improving the grounding stability of the grounding frame 2. When pressing the base 1, the grounding frame 2 is pushed upward by the ground due to the influence of the ground.

[0036] If the soil is soft, you can first press the grounding frame 2 downward quickly and forcefully, so that the grounding frame 2 is inserted vertically and firmly into the soil along the sliding rod 4. Since the deeper the soil, the more difficult it is to press down, therefore, when the grounding frame 2 moves downward to the junction of the thin section and the thick section of the sliding rod 4, start to rotate the grounding frame 2 counterclockwise, and the grounding frame 2 gradually squeezes the sliding rod 4 to slide to the side of the compressed first spring 5. At this time, the sliding rod 4 pulls the first sliding block 6 to slide horizontally along the base 1 through the first tension spring 7, so that the two first sliding blocks 6 contact each other, so that the internal thread of the first sliding block 6 and the external thread of the grounding frame 2 match each other, and continue to rotate the grounding frame 2 counterclockwise, and the grounding frame 2 can be inserted deep into the soil in a spiral manner.

[0037] If the soil is hard, it is difficult to press the ground frame 2 downward, so the ground frame 2 is directly rotated counterclockwise from the beginning, so that the two first sliders 6 contact each other, so that the internal thread of the first slider 6 matches the external thread of the ground frame 2. When the ground frame 2 moves downward to the junction of the thin section and the thick section of the slide rod 4, since the two first sliders 6 have contacted each other, the first slider 6 has no space for further sliding. At this time, the ground frame 2 continues to be rotated counterclockwise, and only the thick section of the slide rod 4 is squeezed by the outer edge of the circumference of the ground frame 2, and slides to the side that continues to compress the first spring 5. The slide rod 4 slides relative to the first slider 6 to stretch the first tension spring 7, and finally the ground frame 2 can be inserted deep into the soil in a spiral manner.

[0038] After the grounding frame 2 is inserted into the soil, the port of the ground wire is pulled to connect to the power grid that needs to be operated and maintained. During the process of pulling the ground wire, the ground coil 3 rotates counterclockwise on the grounding frame 2. After connection, the current of the power grid is transmitted to the ground through the ground coil 3 and the grounding frame 2, thereby achieving rapid grounding. When the device needs to be dismantled and removed, the grounding frame 2 is first rotated clockwise. When the slot of the grounding frame 2 corresponds to the slide bar 4, the first spring 5 is reset to drive the slide bar 4 to bounce into the slot of the grounding frame 2. The slide bar 4 pushes the first slider 6 to reset through the first tension spring 7, so that the two first sliders 6 are disengaged from each other, thereby causing the internal thread of the first slider 6 to disengage from the external thread of the grounding frame 2, and then the grounding frame 2 can be pulled out upward.

[0039] In summary, when the soil is soft, the present invention can quickly connect the grounding frame 2 to the ground by first pressing it down quickly and then screwing the grounding frame 2. When the soil is hard, the grounding frame 2 can be screwed all the way to achieve grounding. Moreover, through the action of the grounding frame 2 and the sliding rod 4, the entire device is relatively stable and firm and will not fall over. It not only meets the function of rapid grounding, but also flexibly adapts to different geological environments and takes into account stability.

[0040] like Figure 4 and Figure 5 As shown, it also includes a screw rod 8, which is slidably connected to the ground frame 2 along the up and down directions. The middle part of the ground frame 2 is horizontally slidably connected to a second slider 9 symmetrically distributed along the front and back of the ground frame 2. The second slider 9 is provided with an internal thread on the side close to the screw rod 8. When the two second sliders 9 contact each other, the second slider 9 engages with the external thread of the screw rod 8 through the internal thread. A guide frame 10 is slidably connected to the ground frame 2 along the up and down directions. The top end of the guide frame 10 is rotatably connected to the bottom end of the screw rod 8. Two clamping rods 11 are slidably connected to the ground frame 2 in an oblique upward direction. The ground frame 2 has two through holes for the clamping rod 11 to pass through. The guide frame 10 has an oblique groove slidably connected to the clamping rod 11. When the guide frame 10 moves downward, it pushes the clamping rod 11 to be inserted obliquely upward into the soil.

[0041] When the grounding frame 2 is finally spirally inserted into the soil, first push the second slider 9 outward so that the two second sliders 9 are not in contact, and then push the screw rod 8 downward, thereby driving the guide frame 10 to move downward. The guide frame 10 squeezes the clamping rod 11 through the inclined groove and moves obliquely upward, and moves out from the through hole of the grounding frame 2, and is inserted into the soil like a "barb". In this way, the grounding frame 2 is difficult to pull out, so that it is more firmly inserted into the soil. When the soil is hard and the clamping rod 11 is difficult to insert into the soil, thereby making it difficult to push the screw rod 8 downward, hold the two second sliders 9 with the tiger's mouth of the hand so that the two second sliders 9 are in contact, and use a wrench to turn the screw rod 8. Under the cooperation of the internal threads of the screw rod 8 and the second slider 9, the screw rod 8 rotates and moves downward, so that the clamping rod 11 can be inserted into the harder soil.

[0042] When the grounding frame 2 needs to be pulled out, the screw rod 8 is operated in reverse so that the screw rod 8 drives the guide frame 10 to move upward, and the guide frame 10 pulls the clamping rod 11 through the inclined slot to move obliquely downward into the grounding frame 2, so that the grounding frame 2 can be pulled out.

[0043] like Figure 6 and Figure 7 As shown, it also includes a first guide block 12, which is fixedly connected to the top front side of the base 1, and a slope is set on the front side of the first guide block 12. A fixed rod 13 is fixedly connected to the upper front side of the grounding frame 2. The fixed rod 13 does not contact the sliding rod 4 when rotating with the grounding frame 2. The fixed rod 13 is connected to a clamping block 14 that slides along the front-back direction. The clamping block 14 is engaged with the ground coil 3. The clamping block 14 moves downward and contacts with the slope of the first guide block 12, so that the clamping block 14 slides forward to release the clamping block 14 from locking the ground coil 3. An arc surface 141 is set on the right side of the clamping block 14, and a straight surface is set on the left side of the clamping block 14, so that the ground coil 3 can only rotate unidirectionally clockwise when the clamping block 14 is clamped, so that the ground wire can only be wound but not pulled out, and a second spring 15 is fixedly connected between the fixed rod 13 and the clamping block 14.

[0044] The fixing rod 13, the clamping block 14 and the second spring 15 descend synchronously with the grounding frame 2 and the ground coil 3. When the ground coil 3 descends together with the grounding frame 2, the clamping block 14 clamps the ground coil 3 to prevent the ground wire from being torn apart at will before the grounding frame 2 is firmly inserted into the ground. When the clamping block 14 descends to contact the inclined surface of the first guide block 12, the clamping block 14 slides along the fixing rod 13 to the side of the compressed second spring 15 under the squeezing effect of the inclined surface of the first guide block 12, so that the clamping block 14 no longer clamps the ground coil 3, so that the ground coil 3 can rotate counterclockwise on the grounding frame 2, and then the port of the ground wire can be pulled to be connected to the power grid that needs to be operated and maintained.

[0045] When the ground coil 3 rises together with the grounding frame 2, the fixing rod 13, the block 14 and the second spring 15 rise synchronously. When the block 14 is disengaged from the first guide block 12, the block 14 slides along the fixing rod 13 and is inserted into the ground coil 3 under the reset action of the second spring 15. Due to the action of the arc surface 141, the ground coil 3 can rotate clockwise on the grounding frame 2, so that the ground wire can be wound.

[0046] In summary, the present invention, through the arrangement of components such as the clamping block 14 and the first guide block 12, ensures that the ground wire will not become loose before the wiring frame is fully inserted and fixed. In this way, the user is forced to fully insert the grounding frame 2 into the soil to ensure that the grounding frame 2 reaches a sufficient depth, thereby improving the reliability and safety of the grounding; at the same time, it prevents wiring operations when the grounding frame 2 is not fully inserted, thereby ensuring the standardization of the operation, preventing misoperation, and reducing safety hazards caused by poor grounding.

[0047] like Figure 1 and Figure 8 As shown, it also includes a second tension spring 16 symmetrically distributed along the front and back of the grounding frame 2, the second tension spring 16 corresponds to the second slider 9 one by one, one end of the second tension spring 16 is fixedly connected to the grounding frame 2, and the other end is fixedly connected to the corresponding second slider 9, and the top of the base 1 is fixedly connected to a second guide block 17 symmetrically distributed along the front and back of the grounding frame 2, and the second guide block 17 is provided with an inclined surface on the side close to the grounding frame 2, and the second guide block 17 corresponds to the second slider 9 one by one, and the second slider 9 moves downward and contacts with the corresponding inclined surface of the second guide block 17, and the second guide block 17 is used to push the two second sliders 9 to contact each other, and a third spring 18 is fixedly connected between the guide frame 10 and the grounding frame 2.

[0048] Initially, the two second sliders 9 are not in contact, and the screw rod 8 cannot cooperate with the internal thread of the second slider 9. At this time, although the screw rod 8 can be pressed downward to make the clamping rod 11 extend out and insert into the soil, due to the presence of the third spring 18, the clamping rod 11 will also retract into the ground frame 2 at the moment of loosening the screw rod 8. In this way, before the ground frame 2 is firmly inserted into the ground, it is difficult to insert the clamping rod 11 into the soil, avoiding premature operation of the screw rod 8, thereby avoiding the clamping rod 11 from being stuck on the soil surface or in the shallow soil in advance, making it difficult for the ground frame 2 to continue to be smoothly and quickly inserted to the predetermined depth.

[0049] When the grounding frame 2 is inserted to a predetermined depth, the second slider 9 contacts the second guide block 17. Due to the squeezing effect of the inclined surface of the second guide block 17, the two second sliders 9 are close to each other and contact each other, the second tension spring 16 is stretched, and the screw rod 8 can cooperate with the internal thread of the second slider 9. At this time, rotating the screw rod 8 can extend the clamping rod 11, and the downward movement of the guide frame 10 will compress the third spring 18. At this time, since the second slider 9 locks the screw rod 8 through the internal thread to prevent the screw rod 8 from returning, the third spring 18 maintains a compressed state, thereby preventing the clamping rod 11 from returning. That is, only when the grounding frame 2 is inserted to a predetermined depth can the clamping rod 11 be firmly inserted into the soil.

[0050] When removing the device, at the moment when the second slider 9 is disengaged from the second guide block 17, the second tension spring 16 is reset, causing the two second sliders 9 to slide away from each other. At this time, the third spring 18 is reset to drive the guide frame 10 to rebound upward quickly, thereby driving the screw rod 8 to move upward and reset, and at the same time causing the clamping rod 11 to automatically retract into the grounding frame 2, without the need to reversely rotate the screw rod 8, thereby improving the convenience of operation.

[0051] like Fig. 9 and Fig.10 As shown, it also includes a bracket 19 that is symmetrically distributed along the grounding frame 2. The bracket 19 is slidably connected to the grounding frame 2. The outer end of the bracket 19 is engaged with the ground coil 3. The inner end of the bracket 19 is in contact with the screw 8. A groove 191 is opened on the side of the screw 8 close to the bracket 19. The screw 8 drives the groove 191 to move downward to align with the bracket 19. A fourth spring 20 is fixed between the bracket 19 and the grounding frame 2.

[0052] Initially, the ground coil 3 is clamped by the clamping frame 19, and the screw rod 8 moves downward to drive the groove 191 to move downward. When the groove 191 is aligned with the clamping frame 19, the clamping rod 11 is completely inserted into the soil. At the same time, the fourth spring 20 in the compressed state resets and drives the clamping frame 19 to be clamped into the groove 191, so that the clamping frame 19 no longer clamps the ground coil 3, so that the ground coil 3 can rotate counterclockwise on the grounding frame 2, and then the port of the ground wire can be pulled to connect with the power grid that needs to be operated and maintained.

[0053] In summary, the present invention forces the user to extend the card rod 11 before wiring through the provision of the card frame 19 and the fourth spring 20, thereby ensuring that the card rod 11 can enhance stability and reliability, and at the same time avoiding wiring operations when the card rod 11 is not extended, thereby ensuring the standardization of operations, preventing misoperation, and reducing safety hazards caused by poor grounding.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
