Description

Technical Field

[0001] This utility model relates to the field of substation grounding construction technology, specifically to an insulation grounding device for power substation construction. Background Technology

[0002] A substation is a place in a power system where the voltage and current of electrical energy are transformed, concentrated, and distributed. A substation raises the low-voltage electrical energy generated by a power plant to a suitable high voltage through transformers to reduce energy loss during transmission and enable long-distance transmission. At the same time, it lowers the high-voltage electrical energy to a low voltage suitable for users to meet the electricity needs of different users.

[0003] In substation construction, insulation and grounding equipment plays a crucial role. A conductor that carries current to the earth connects one end to a grounding electrode and the other end to the grounding terminal of the equipment. During substation construction, grounding wires are used to ensure the safe grounding of electrical equipment under normal and fault conditions, preventing electric shock hazards caused by equipment leakage.

[0004] A related technology (publication number: CN221479185U) discloses an insulation grounding device for power substation construction. The disclosed technical solution involves: pulling a pull plate to move the locking post outwards until it moves out of the locking hole, releasing the locking of the insulation winding frame; then rotating the control wheel to unwind the insulation winding frame until the exposed wire length is appropriate; finally, locking the insulation winding frame again via the locking post. The wire length can be adjusted according to the distance between the insulation grounding device and the substation, eliminating the need to carry a large amount of wire during installation. The box is then placed in the installation position, the grounding rod is inserted into the ground, and the box is installed on the ground using grounding nails, making the installation more stable. Finally, the exposed end of the wire in the box is connected to the substation. The substation, wire, metal conductive sleeve, and metal connecting sleeve can form a conductive path. Furthermore, when carrying the insulation device, the wire can be wound into the box, facilitating the transport of the insulation device.

[0005] The above-disclosed technical solutions reveal the following problems: During substation construction, the box-type insulation structure occupies a large space, and the space inside the box results in poor overall load-bearing capacity of the box-type insulation grounding structure, making it unable to bear weight in certain locations, thus limiting the installation location during construction. To address this, we propose a new type of insulation grounding device for power substation construction.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art.

[0007] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the substation construction grounding problem in the prior art, this utility model provides a power substation construction insulation grounding device. It employs a cylindrical structure combined with a grounding conductivity adjustment structure to achieve ease of portability and construction. The specific technical solution is as follows:

[0009] In the above technical solution, the opposing linkage assembly includes a rotating cylinder rotatably disposed in the inner cavity of the insulating cylinder, two connecting posts symmetrically facing each other and threadedly connected to the rotating cylinder, and the two connecting posts respectively extending out of both sides of the rotating cylinder, a docking post is embedded in the inner cavity of the rotating cylinder, and the two connecting posts are symmetrically facing each other and sleeved on the outer wall of the docking post, and a rotation drive component for driving the rotating cylinder to rotate is provided on the insulating cylinder.

[0010] The rotary drive component includes a gear ring sleeved on the outer wall of the rotating cylinder, a drive gear rotatably disposed on the outer wall of the insulating cylinder, and a slot is opened on the outer wall of the insulating cylinder, through which the drive gear meshes with the gear ring.

[0011] The top of the insulating cylinder is fixedly fitted with a wire cover that is sleeved on the outside of the connecting wire. Inside the wire cover is a support that fits against the outer wall of the connecting wire. A movable column is provided through the outer wall of the wire cover. The end of the movable column extending into the inner cavity of the wire cover is fixedly fitted with a locking seat opposite to the support. A locking member for adjusting the position of the locking seat is provided on the outer wall of the wire cover.

[0014] An insulated winding post is fixed to the top of the conductive disk, and the connecting wire is wound around the outer wall of the insulated winding post.

[0015] Both the ground cone and the grounding post are conductors.

[0018] Second, the cylindrical structure can be directly installed on the corresponding position during construction using a ground cone, forming an integrated structure with the ground cone. This facilitates the construction process, makes the structure easy to carry, and thus ensures the efficiency of the substation construction process.

[0019] Third, the locking mechanism causes the movable column to move the wire locking seat towards the backrest, stretching the connecting wire to a sufficient length, and then fixing the connecting wire through the wire locking seat, thereby ensuring the stability when connected to the equipment.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] An insulation and grounding device for power substation construction includes an insulating cylinder 1, with a ground cone 2 fixedly connected to the bottom of the insulating cylinder 1. The ground cone 2 is a cone structure with its tip pointing downwards. The ground cone 2 is fixedly installed at the bottom of the insulating cylinder 1, and the insulating cylinder 1 is inserted into the ground through the tip of the ground cone 2, thereby fixing the insulating cylinder 1 in the corresponding position. A grounding post 5 is embedded in the inner cavity of the ground cone 2. The grounding post 5, made of conductive material, is fixedly embedded inside the ground cone 2, so that the grounding post 5 and the ground cone 2 are electrically conductive to each other.

[0029] A conductive disk 3 is embedded in the top of the inner cavity of the insulating cylinder 1. The conductive disk 3, made of conductive material, is fixedly embedded inside the insulating cylinder 1 and positioned near the top of the insulating cylinder 1. A connecting wire 4 extending from the top of the insulating cylinder 1 is fixedly connected to the top of the conductive disk 3. The lower end of the connecting wire 4 is fixedly installed on the top of the conductive disk 3, and the top of the connecting wire 4 extends outward through the top of the insulating cylinder 1, allowing mutual conductivity between the connecting wire 4 and the conductive disk 3. Symmetrically arranged in the inner cavity of the insulating cylinder 1 are opposing moving connecting posts 7, and the inner cavity of the insulating cylinder 1 is equipped with an opposing linkage assembly that drives the two connecting posts 7 to respectively engage with the conductive disk 3 and the grounding post 5. The connecting posts 7 are made of conductive material.

[0030] The two connecting posts 7 move back-to-back via a counter-linking assembly, allowing them to connect to the conductive plate 3 and the grounding post 5 respectively. This grounds the connecting wire 4, allowing current to be introduced to the earth. One end of the connecting wire 4 is connected to the grounding electrode, and the other end is connected to the grounding terminal of the equipment. This ensures safe grounding of electrical equipment under normal and fault conditions, preventing electric shock hazards in case of equipment leakage. The cylindrical structure allows for direct installation at the corresponding location via the grounding cone 2 during construction, forming an integrated structure with it. This facilitates construction, makes the equipment easy to carry, and ultimately ensures efficiency in substation construction.

[0031] The opposing linkage assembly includes a rotating cylinder 6 rotatably disposed within the inner cavity of the insulating cylinder 1. The rotating cylinder 6 rotates continuously circumferentially within the inner cavity of the insulating cylinder 1. Two connecting posts 7 are symmetrically and oppositely threaded to the rotating cylinder 6, and the two connecting posts 7 extend from both sides of the rotating cylinder 6. Two internal threads with opposite threads and the same pitch are formed on the inner wall of the rotating cylinder 6 from the center outwards. External threads 12 are formed on the outer wall of the two connecting posts 7 near their ends of the rotating cylinder 6, allowing the two connecting posts 7 to move relative to or away from each other when the rotating cylinder 6 rotates.

[0032] A docking post 16 is embedded in the inner cavity of the rotating cylinder 6, and two connecting posts 7 are symmetrically sleeved on the outer wall of the docking post 16. A fixing seat 17 is fixedly sleeved on the outer wall of the docking post 16, and the fixing seat 17 is fixedly embedded in the middle of the inner cavity of the rotating cylinder 6. A groove 18 is opened at the end of each of the two connecting posts 7 near the docking post 16, so that the connecting post 7 slides against the outer wall of the conductive material docking post 16 during movement. The conductive material docking post 16 ensures electrical conduction between the two connecting posts 7. A rotation drive component is provided on the insulating cylinder 1 to drive the rotating cylinder 6 to rotate.

[0033] It is worth noting that the rotary drive component includes a gear ring 10 sleeved on the outer wall of the rotary cylinder 6. The outer wall of the rotary cylinder 6 is fixedly sleeved with a movable seat 9, and the outer ring seat 8 is fixedly embedded in the inner wall of the insulating cylinder 1. A circumferential groove 28 is opened on the inner wall of the outer ring seat 8, and a circumferential movable groove 27 is sequentially opened on the outer wall of the movable seat 9. A ball bearing 26 is movably embedded in the movable cavity formed by each movable groove 27 and the groove 28.

[0034] A drive gear 11 is rotatably mounted on the outer wall of the insulating cylinder 1. A slot 13 is formed in the outer wall of the insulating cylinder 1, through which the drive gear 11 passes and meshes with a gear ring 10. The gear ring 10 is fixedly sleeved on the top of the outer wall of the rotating cylinder 6. The slot 13, extending into the inner cavity, is located on the outer wall of the insulating cylinder 1, corresponding to the position of the gear ring 10. Supports fixed to the outer wall of the insulating cylinder 1 are provided on both sides of the slot 13. Bearings are embedded in the opposite surfaces of the two supports. The two ends of the movable shaft are respectively embedded in the two bearings. The drive gear 11 is fixedly sleeved on the outer wall of the movable shaft through a central mounting hole. The top end of the movable shaft passes through one of the supports and extends outwards, with an operating rod fixedly connected to the extended movable shaft.

[0035] The operating lever drives the drive gear 11 to rotate, and the gear ring 10 that meshes with the drive gear 11 drives the rotating cylinder 6 to rotate, thereby connecting the connecting wire 4 to the grounding post 5.

[0036] In addition, a wire protector 15, which is sleeved on the outside of the connecting wire 4, is fixedly attached to the top of the insulating cylinder 1. A support 19, which fits against the outer wall of the connecting wire 4, is fixedly attached inside the wire protector 15. The circular wire protector 15 is fixedly installed on the top of the insulating cylinder 1, and the connecting wire 4 passes through the inner cavity of the wire protector 15 to connect with the equipment. A movable column 21 is provided through the outer wall of the wire protector 15. A locking seat 23, which is opposite to the support 19, is fixedly attached to the end of the movable column 21 extending into the inner cavity of the wire protector 15. A locking member for adjusting the position of the locking seat 23 is provided on the outer wall of the wire protector 15. The arc-shaped support 19 is fixed on the inner wall of the wire protector 15. The locking seat 23, which has the same shape as the support 19, is in the inner cavity of the wire protector 15. The movable column 21 passes through the side wall of the wire protector 15, so that the movable column 21 slides in the through hole of the wire protector 15.

[0037] The locking mechanism causes the movable column 21 to move the locking seat 23 toward the backrest 19, stretching the connecting wire 4 to a sufficient length and then fixing it to the connecting wire 4 through the locking seat 23, thereby ensuring the stability when connected to the equipment.

[0038] Additionally, the locking component includes a sleeve 24 fixed to the outer wall of the cable guard 15. A threaded post 20 is rotatably mounted on the end of the movable post 21 located outside the cable guard 15, and the sleeve 24 is threadedly connected to the outside of the threaded post 20. The sleeve 24 is fixedly installed on the outer wall of the cable guard 15, such that the sleeve 24 and the movable post 21 are on the same straight line. The inner cavity of the sleeve 24 is threadedly connected to the threaded post 20, and both ends of the threaded post 20 extend outwards from both sides of the sleeve 24. A spherical component 25 is fixedly mounted on one end of the threaded post 20. The end of the movable post 21 located outside the cable guard 15 is hemispherical, and a spherical cavity 22 is formed at the hemispherical end, allowing the spherical component 25 to be movably embedded within the spherical cavity 22, enabling the spherical component 25 to rotate freely within the end of the movable post 21.

[0039] During the process of adjusting the position of the locking seat 23 by rotating the threaded column 20, the threaded column 20 drives the ball part 25 to rotate and pushes the movable column 21 to move, so that the movable column 21 drives the locking seat 23 to move towards the seat 19, thereby locking and fixing the connecting wire 4.

[0040] The top of the insulating cylinder 1 is conical. The conical top provides protection for the insulating cylinder 1.

[0041] Furthermore, an insulated winding post 14 is fixedly attached to the top of the conductive disk 3, and the connecting wire 4 is wound around the outer wall of the insulated winding post 14. The wire is wound up by the insulated winding post 14, so that when docking with the equipment, a sufficiently long connecting wire 4 can be stretched out according to the wiring position.

[0042] Both ground cone 2 and grounding post 5 are conductors.
