Description

Technical Field

[0001] The invention relates to the technical field of conductive connection, and in particular to a grounding discharge device for line maintenance in a distribution network. Background Art

[0002] Distribution network line maintenance refers to the process of regular inspection, maintenance and repair of transmission lines, substations, distribution equipment, etc. in the distribution network. The distribution network is an important part of the power system and is responsible for transmitting electricity from the substation to the user end. Since the distribution network lines are exposed to the outdoors for a long time and are affected by the natural environment and usage conditions, they may experience aging, damage, and reduced insulation performance. Therefore, regular maintenance is a necessary measure to ensure the safe and stable operation of the distribution network and improve the reliability of power supply.

[0003] During the maintenance of distribution network lines, in order to ensure the safety of maintenance personnel, it is usually necessary to use a grounding discharge device to safely discharge the residual charge in the line to the ground before maintenance to prevent electric shock accidents during the maintenance process.

[0004] During ground discharge, the grounding end needs to be inserted into the ground, and then connected to the line to be discharged by connecting the grounding wire. In this way, the charge in the line can be safely introduced into the ground through the grounding wire to ensure the safety of the maintenance personnel. After the discharge is completed, it is necessary to check and confirm that the line is completely de-energized before the maintenance work can be started. For example, a grounding discharge device for distribution network line maintenance with the publication number CN116365263A relates to the field of ground discharge technology. The prior art includes a sleeve, the inner ring of the sleeve is connected with a metal rod for rotation, the top of the metal rod is fixed with a terminal head, the outer ring of the sleeve is provided with a spiral groove, the lower end of the metal rod is fixed with a cone head, and a plurality of discharge mechanisms are installed in the vertical array inside the sleeve. All the discharge mechanisms are used to introduce the current connected by the metal rod into the ground. After the sleeve is fixed on the ground, the discharge mechanism is driven by the rotating adjustment mechanism to fully contact with the soil under the ground, and then the soil at the position of the discharge mechanism is subjected to resistance reduction treatment by the provided resistance reduction mechanism, so as to prevent the discharge device from burning out due to excessive resistance value. Finally, the staff connects one end of the grounding wire to the terminal head.

[0005] However, the above-mentioned prior art still has some defects when it comes to ground discharge: 1. The above-mentioned prior art uses the cone head at the lower end of the metal rod to insert the sleeve and the metal rod into a part below the ground, and cooperates with the spiral groove provided on the outer ring of the sleeve to facilitate the installation of the sleeve and the metal rod underground, and then uses a fixing component to fix the sleeve inserted into the ground, and the discharge mechanism is driven by the rotating adjustment mechanism to fully contact the soil under the ground to release the current. However, in the actual maintenance application process, some on-site environments that require grounding discharge do not have soft ground such as soil for the metal rod to insert, but hard ground such as cement ground. The cone head at the lower end of the metal rod is directly inserted into the ground, resulting in the metal rod being unable to effectively perform grounding discharge.

[0006] 2. The above-mentioned prior art inserts the sleeve and the metal rod into a part below the ground through the cone head at the lower end of the metal rod, and cooperates with the spiral groove provided on the outer ring of the sleeve to facilitate the installation of the sleeve and the metal rod underground to achieve power connection and discharge. However, in actual application, the conductivity of the soil mainly depends on factors such as its water content, temperature, salt content, organic matter content and soil type. For example, dry soil usually has poor conductivity due to its low water content, which will lead to an increase in grounding resistance, thereby affecting the effect of grounding discharge.

[0007] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for ground discharge. Summary of the invention

DETAILED DESCRIPTION

[0038] The following is combined with Figures 1 to 10 The present invention is described in further detail.

[0039] The embodiment of the present invention discloses a grounding discharge device for power distribution network line maintenance, which performs grounding discharge by using conductive liquid to contact the ground or using conductive liquid to infiltrate soil.

[0040] Embodiment 1: Reference Figure 1 and Figure 2 As shown, a grounding discharge device for distribution network line maintenance includes a support box 1, a separator ring 2 is arranged in the support box 1, and the lower end of the separator ring 2 passes through the support box 1. During the distribution network line maintenance process, in order to ensure the safety of the maintenance personnel, the residual charge in the line is safely released to the ground through grounding discharge before maintenance, so as to prevent electric shock accidents during the maintenance process.

[0041] When grounding discharge is performed on a hard ground such as a cement ground, the support box 1 is first placed on the ground through a plurality of support legs 11 provided at the bottom of the support box 1, and then a conductive liquid is injected into the water storage chamber 21 formed between the separation ring 2 and the support box 1. At this time, the conductive liquid is used as a counterweight.

[0042] The weight of the conductive liquid will cause the water storage conductor 3 provided on the support box 1 to form a sealed area with the hard ground. The water storage conductor 3 is located in the separation ring 2. Then the water storage conductor 3 will inject the conductive liquid into the sealed area formed between it and the hard ground. The conductive liquid will be in close contact with the ground in the sealed area to discharge.

[0043] When grounding discharge is performed on soft ground such as soil, the water storage conductor 3 also forms a sealing area with the hard ground, and then the grounding conductor 4 arranged on the support box 1 will be started, and the grounding conductor 4 will be grounded by drilling into the soil, and then the water storage conductor 3 will inject conductive liquid into the sealing area formed between it and the hard ground, and the conductive liquid will penetrate into the soil in the sealing area, thereby improving the conductivity of the soil.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the water storage conductor 3 includes a sealing cylinder 34 slidably arranged in the separation ring 2, a ring sleeve 36 located at the lower side of the separation ring 2 is arranged on the sealing cylinder 34, and a water supporting plate 31 is slidably arranged in the water storage cavity 21.

[0045] When grounding discharge is performed on a hard ground such as a cement ground, the support box 1 is first placed on the ground through the support legs 11, and then a conductive liquid is injected into the water storage chamber 21. At this time, the conductive liquid is used as a counterweight.

[0046] When placing the support box 1 on the ground through the support legs 11, the sealing ring 361 set at the lower end of the ring sleeve 36 will contact the hard ground. Then the support box 1 continues to move downward to compress the return spring 35 set between the upper end of the sealing cylinder 34 and the support box 1. The compressed return spring 35 will push the sealing cylinder 34, so that the ring sleeve 36 presses the sealing ring 361. The sealing ring 361 will be deformed and in close contact with the ground. Under the action of the sealing ring 361, the sealing cylinder 34 and the hard ground form a sealing area.

[0047] Then, rotate the adjusting screw 32 that is rotatably installed on the supporting box 1. The adjusting screw 32 is threadedly connected with the water supporting plate 31 to move the water supporting plate 31 upward. The moving water supporting plate 31 will support the conductive liquid to move upward, so that the conductive liquid rises together. The guiding slope 311 inclined toward the separating ring 2 arranged on the water supporting plate 31 will guide the conductive liquid to the separating ring 2, so that the conductive liquid passes through the several water inlet holes 33 circumferentially opened at the upper end of the separating ring 2 and enters the upper end of the sealing tube 34, and then enters into the sealing area from the connecting hole opened at the upper end of the sealing tube 34. The conductive liquid will fully contact the ground in the sealing area to discharge.

[0048] Continue to refer to Figure 1 , Figure 2 and Figure 3As shown, a water blocking ring 37 is rotatably provided on the upper side of the separation ring 2 , and a water inlet groove 371 corresponding to the water inlet hole 33 is opened on the water blocking ring 37 , and an arc-shaped adjustment hole 38 is opened on the support box 1 .

[0049] By moving the adjusting rod 39 slidingly arranged in the arc-shaped adjusting hole 38, the adjusting rod 39 will drive the water blocking ring 37 to rotate on the separating ring 2 through the connection with the water blocking ring 37, so that the water inlet groove 371 and the water inlet hole 33 overlap and communicate with each other, so that the conductive liquid can smoothly flow into the upper end of the sealing tube 34 in the separating ring 2.

[0050] In the process of injecting conductive liquid into the water storage chamber 21 and moving the support box 1, by toggling the adjusting rod 39, the adjusting rod 39 drives the water blocking ring 37 to rotate on the separating ring 2, so that the water inlet groove 371 and the water inlet hole 33 are blocked with each other, so that the conductive liquid cannot flow into the upper end of the sealing tube 34 in the separating ring 2, thereby avoiding the loss of the conductive liquid.

[0051] Reference Figure 5 and Figure 6 As shown, specifically, the grounding conductor 4 includes a driving shaft 42 passing through the supporting box 1, the lower end of the driving shaft 42 rotates and slides through the sealing cylinder 34 and then a rotating cylinder 43 is provided, and the lower end of the rotating cylinder 43 rotates and slides through the ring sleeve 36 and then a cutting blade 44 is provided.

[0052] When grounding discharge is performed on soft ground such as soil, the support box 1 is first placed on the ground through the support legs 11, so that the ring sleeve 36 presses the sealing ring 361, and the sealing ring 361 sinks into the soft ground. Under the action of the sealing ring 361, the sealing tube 34 forms a sealing area with the soft ground.

[0053] Then, by driving the driving gear 41 rotatably arranged on the supporting box 1 to rotate, the rotating driving gear 41 will drive the driving shaft 42 to rotate through the axial sliding connection with the driving shaft 42, and the rotating driving shaft 42 will move downward through the threaded connection with the supporting box 1. At the same time, the rotating driving shaft 42 will drive the rotating drum 43 to rotate together and drive the rotating drum 43 to move downward together. The rotating rotating drum 43 will cut the soil through the cutting blade 44 arranged at its lower end, so that the rotating drum 43 drills into the soil.

[0054] Then, the adjusting screw 32 is rotated to move the water supporting plate 31 upward, so that the conductive liquid passes through the water inlet hole 33 and enters the upper end of the sealing cylinder 34, and then enters the water inlet cavity 45 formed between the rotating cylinder 43, the sealing cylinder 34 and the ring sleeve 36 from the connecting hole opened at the upper end of the sealing cylinder 34. The conductive liquid in the water inlet cavity 45 will pass through a plurality of connecting holes 46 opened circumferentially on the rotating cylinder 43 and enter the rotating cylinder 43. The conductive liquid will penetrate into the soil in the rotating cylinder 43, thereby improving the conductivity of the soil and increasing the discharge effect. Subsequently, the rotating cylinder 43 is connected to the discharge source through a wire, and the current is introduced into the soil through the rotating cylinder 43.

[0055] It should be noted that when grounding discharge is performed on a hard ground such as a cement ground, the wire guides the discharge source to the rotating drum 43, and the rotating drum 43 is located in the conductive liquid in the sealing cylinder 34, so that the rotating drum 43 can guide the discharge source into the conductive liquid, and then perform grounding discharge through the conductive liquid.

[0056] Embodiment 2: Reference Figure 6 , Figure 7 and Figure 8 As shown, on the basis of the first embodiment, a conductive stabilizer 5 is arranged in the sealing cylinder 34 .

[0057] The conductive stabilizer 5 includes a conductive support ring 51 slidably disposed in the sealing cylinder 34 and rotatably connected to the rotating cylinder 43. A plurality of stabilizing rods 52 are rotatably penetrated on the conductive support ring 51. The lower end of the stabilizing rod 52 rotates and slides through the ring sleeve 36 and the sealing ring 361, and a stabilizing cone 6 is disposed thereafter.

[0058] When ground discharge is performed on a soft ground such as soil, the rotation of the rotating drum 43 will drive the transmission gear 53 provided on the upper end of the rotating drum 43 to rotate together. The rotating transmission gear 53 will drive the driven gear 54 provided on the stabilizing rod 52 to rotate through meshing. The rotating driven gear 54 will drive the stabilizing rod 52 to rotate on the conductive support ring 51. At the same time, the downward movement of the rotating drum 43 will drive the conductive support ring 51 to move downward in the sealing tube 34. The downward moving conductive support ring 51 will drive the stabilizing rod 52 to move downward and drill into the soil through the stabilizing cone 6 provided at the lower end of the stabilizing rod 52.

[0059] During this process, a drainage hole 55 is opened in the stabilizing rod 52, and a drainage groove 56 connecting the drainage hole 55 and the water inlet chamber 45 is opened on the stabilizing rod 52. The drainage groove 56 will be drilled into the soil together with the stabilizing rod 52, and a part of it is located in the water inlet chamber 45. For ease of understanding, the part of the drainage groove 56 located in the water inlet chamber 45 is defined as the drainage upper groove 57, and the part of the drainage groove 56 drilled into the soil is defined as the drainage lower groove 58.

[0060] After the conductive liquid enters the water inlet chamber 45, a portion of the conductive liquid will pass through the connecting hole 46 and enter the drum 43. The conductive liquid entering the drum 43 will seep into the soil. At the same time, a portion of the conductive liquid will pass through the upper drainage groove 57 and enter the drainage hole 55, and then flow out from the lower drainage groove 58, so that the conductive liquid seeps into the soil around the stabilizing rod 52 and the soil outside the drum 43, further improving the conductivity of the soil.

[0061] Then, the drum 43 is connected to the discharge source through a wire, and the drum 43 is connected to the stabilizing rod 52 through the electrical connection with the conductive support ring 51. The discharge is performed through the stabilizing rod 52 and the drum 43. The stabilizing rod 52 increases the contact area and contact points with the soil, thereby improving the efficiency of ground discharge.

[0062] Among them, the stabilizing cone 6 includes a plurality of conical lobes 61 circumferentially hinged at the lower end of the stabilizing rod 52, and the plurality of conical lobes 61 are mutually abutted and connected to form a pointed cone. An electric push rod 62 is arranged in the drainage hole 55 through a bracket, and a connecting rod 63 hinged to the conical lobes 61 is rotatably arranged at the telescopic end of the electric push rod 62.

[0063] After the stabilizing rod 52 drives the stabilizing cone 6 to drill into the predetermined position in the soil, the telescopic end of the electric push rod 62 will extend, and the telescopic end of the electric push rod 62 will push the connecting rod 63 hinged to the conical leaf 61, so that the multiple conical leaf lobes 61 are flipped around the hinge point through the connecting rod 63. At this time, the conical leaf lobes 61 are expanded in the soil to increase the contact area with the soil, and at the same time can stably fix the support box 1.

[0064] When ground discharge is performed on a hard ground such as a cement ground, the sealing ring 361 is provided with receiving holes 64 corresponding to the conical lobes 61 one by one.

[0065] First, the telescopic end of the electric push rod 62 will push the connecting rod 63 hinged between the conical lobes 61, and the multiple conical lobes 61 will flip around the hinge point through the connecting rod 63, so that the stabilizing cone 6 is in an expanded state, and then, driven by the rotating drum 43, the expanded stabilizing cone 6 moves into the accommodating hole 64.

[0066] The compressed return spring 35 will push the sealing tube 34, so that the ring sleeve 36 will press the sealing ring 361. When the sealing ring 361 is deformed and in close contact with the ground, the grounding end 65 on the conical leaf 61 will contact the hard ground, and then the conductive liquid will be injected into the sealing area. At this time, part of the conductive liquid will enter the receiving hole 64 through the drainage groove 56 and the drainage hole 55, fully contact with the ground, and increase the conductivity of the stabilizing rod 52 and the stabilizing cone 6.

[0067] Embodiment three: Reference Fig. 9 and Fig.10 As shown, on the basis of the first and second embodiments, a conductive connector 7 is provided on the supporting box 1 .

[0068] The conductive connector 7 includes vertical frames 71 symmetrically arranged on the support box 1 , a transmission shaft 72 is rotatably arranged between the two vertical frames 71 , and a wire storage wheel 73 is arranged on the transmission shaft 72 .

[0069] The discharge source of the discharge tube is connected through the wire 74 wound on the wire storage wheel 73, and the wire 74 guides the power to the conductive rod 75 embedded in the transmission shaft 72 and connected to it. A conductive ring 76 rotatably connected to the transmission shaft 72 and the conductive rod 75 is provided on a stand 71, and then the discharge source is transmitted to the conductive ring 76 through the electrical connection between the conductive ring 76 and the conductive rod 75.

[0070] A conducting wire (not shown in the figure) is electrically connected between the conductive ring 76 and the conductive support ring 51, and the discharge power is transmitted to the drum 43 through the conducting wire to achieve grounding discharge.

[0071] When the rotating shaft drives the wire storage wheel 73 to rotate to release or recycle the wire 74 , the conductive rod 75 rotates along with the transmission shaft 72 , but the conductive rod 75 is always electrically connected to the conductive ring 76 .

[0072] The implementation principle of the present invention is: (1) When grounding discharge is performed on a hard ground such as a cement ground, the support box 1 is first placed on the ground using a plurality of support legs 11 provided at the bottom of the support box 1, and then a conductive liquid is injected into the water storage chamber 21 formed between the separation ring 2 and the support box 1.

[0073] (2) Then, the support box 1 continues to move downward to compress the return spring 35 provided between the upper end of the sealing cylinder 34 and the support box 1. The compressed return spring 35 pushes the sealing cylinder 34, so that the ring sleeve 36 presses the sealing ring 361. The sealing ring 361 will deform and come into close contact with the ground. Under the action of the sealing ring 361, the sealing cylinder 34 and the hard ground form a sealing area.

[0074] (3) Then, the adjusting screw 32 is rotated, and the water supporting plate 31 moves upward, so that the conductive liquid passes through a plurality of water inlet holes 33 circumferentially opened at the upper end of the separation ring 2 and enters the upper end of the sealing tube 34, and then enters the sealing area from the connecting hole opened at the upper end of the sealing tube 34. The conductive liquid will fully contact the ground in the sealing area to discharge.

[0075] (4) When grounding discharge is performed on a soft ground such as soil, the support box 1 is first placed on the ground through the support legs 11 so that the ring sleeve 36 presses the sealing ring 361, and the sealing ring 361 sinks into the soft ground. Under the action of the sealing ring 361, the sealing tube 34 forms a sealing area with the soft ground.

[0076] (5) Then, the driving shaft 42 is driven to rotate, thereby driving the rotating drum 43 to rotate together and moving the rotating drum 43 downward together. The rotating rotating drum 43 cuts the soil through the cutting blade 44 provided at the lower end thereof, so that the rotating drum 43 drills into the soil.

[0077] (6) Then, the adjusting screw 32 is rotated to move the water supporting plate 31 upward, so that the conductive liquid passes through the water inlet hole 33 and enters the upper end of the sealing cylinder 34 and then enters the rotating cylinder 43. The conductive liquid will penetrate into the soil in the rotating cylinder 43. Then, the rotating cylinder 43 is connected to the discharge source through a wire, and the power source is introduced into the soil through the rotating cylinder 43.

[0078] (7) When ground discharge is performed on a soft ground such as soil, the stabilizing rod 52 rotates on the conductive support ring 51. At the same time, the downward movement of the rotating cylinder 43 drives the conductive support ring 51 to move downward in the sealing cylinder 34. The downward moving conductive support ring 51 drives the stabilizing rod 52 to move downward, and drills into the soil through the stabilizing cone 6 provided at the lower end of the stabilizing rod 52.

[0079] (8) At the same time, a portion of the conductive liquid will enter the drainage hole 55 through the drainage upper groove 57, and then flow out from the drainage lower groove 58, so that the conductive liquid will penetrate into the soil around the stabilizing rod 52 and the soil outside the rotating drum 43, further improving the conductivity of the soil.

[0080] (9) When ground discharge is performed on a hard ground such as a cement ground, the telescopic end of the electric push rod 62 pushes the connecting rod 63 hinged between the conical lobes 61, and the connecting rod 63 causes the multiple conical lobes 61 to flip around the hinge point, so that the fixed cone is expanded. Then, driven by the rotating drum 43, the opened expanded fixed cone moves into the receiving hole 64.

[0081] (10) When the compressed return spring 35 pushes the sealing tube 34, the annular sleeve 36 presses the sealing ring 361. When the sealing ring 361 is deformed and in close contact with the ground, the grounding end 65 on the conical leaf 61 comes into contact with the hard ground. Then, a conductive liquid is injected into the sealing area. At this time, part of the conductive liquid enters the receiving hole 64 through the drainage groove 56 and the drainage hole 55, and is in full contact with the ground, thereby increasing the conductivity of the stabilizing rod 52 and the stabilizing cone 6.

[0082] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
