Description

Technical Field

[0001] The present invention relates to the technical field of intelligent grounding, and specifically provides a non-peeling intelligent grounding device with insulation recovery function. Background Art

[0002] During the overhaul and maintenance of power equipment or wire lines, it is necessary to ensure the reliable grounding of power equipment or wire lines to prevent the harmful voltage generated by sudden power-on from causing harm to the human body, and to discharge the remaining charges of the de-energized equipment or lines, avoid electric shock accidents of operators, and reduce potential safety hazards.

[0003] Currently, existing grounding devices such as Chinese Patent CN206850052U disclose a non-peeling wire grounding adapter device. The grounding adapter device is provided with punctures on the first wire clamping part and the second wire clamping part. When the moving clamp head and the static clamp head cooperate to clamp the wire, the puncture directly penetrates the wire insulation skin and conducts with the wire core. Moreover, the length of the puncture is equal to the thickness of the wire insulation outer skin, and the wire core structure will not be damaged. The current of the wire is transmitted to the terminal through the puncture and the clamp body. When a grounding wire needs to be connected, the grounding wire is directly connected to the grounding connection part, thus realizing the transfer between the wire and the grounding wire; and under the action of the puncture, the first wire clamping part and the second wire clamping part clamp the wire more firmly.

[0004] The above device realizes conduction with the wire core by using the puncture to penetrate the insulation skin, which can avoid the difficulty in mastering the length of the insulation skin to be peeled off during wiring. However, when the grounding device is used for temporary grounding, such as in maintenance or repair processes, after the construction is completed, the puncture needle will leave a pinhole on the insulation layer of the wire, thereby reducing the insulation performance of the insulation layer. Even outdoors, it may cause potential safety hazards due to adhesion of rainwater. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] Please refer to Figures 1 to 10 , the present invention provides a technical solution: a peeling - free intelligent grounding device with an insulation recovery function, including a C - shaped frame 1, and a grounding part is provided below the C - shaped frame 1, and further includes:

[0038] A top cylinder 2 installed at the top inside the frame of the C - shaped frame 1, and a pinhole 9 is opened at the bottom of the top cylinder 2:

[0039] A clamping part that can cooperate with the bottom surface of the top cylinder 2 to clamp and fix the wire, so that the top cylinder 2 is in close contact with the wire skin and isolates the pinhole 9 from the external environment;

[0040] The puncture part includes a puncture needle installed in the top tube 2, and the puncture needle can extend or retract from the needle hole 9;

[0041] The repairing part arranged in the top tube 2 injects liquid insulating material into the needle hole of the wire skin from the needle hole 9 and keeps it in a high pressure state until it solidifies when the puncture needle is retracted into the needle hole 9.

[0042] When the intelligent grounding device is used, the surface of the wire at the puncture position is first cleaned, and then the wire is clamped and fixed by the cooperation between the clamping part and the bottom surface of the top tube 2, and the needle hole 9 is completely attached to the surface of the wire to isolate it from the external environment. Then, the puncture needle in the top tube 2 is controlled by the external structure to extend from the needle hole 9 and pierce the insulating skin of the wire until it contacts the conductive wire core of the wire. Finally, the grounding part is inserted into the ground to complete the grounding process of the wire, and subsequent repair or maintenance can be carried out.

[0043] After use, the external structure controls the puncture needle to be pulled out from the insulation skin of the wire and returned to the pinhole 9. At the same time, the repair part in the top tube 2 injects liquid insulating material from the pinhole 9 into the pinhole on the surface of the wire and keeps it in a high-pressure state until it solidifies, thereby performing insulation repair on the pinhole on the surface of the wire. Then, the top tube is separated from the wire through the clamping part to complete the disassembly process.

[0044] Moreover, it is worth mentioning that the liquid insulating material can be a viscous liquid insulating material such as polyurethane sealant and polysulfide sealant, and it can be quickly cured at room temperature, saving time for subsequent repairs. Moreover, since the pinhole 9 is isolated from the external environment, after the puncture needle is withdrawn from the pinhole, the liquid insulating material can be directly injected into the pinhole to prevent external impurities from entering the pinhole, thereby ensuring the adhesion stability between the insulating material and the puncture hole. Moreover, after the insulating material is injected into the pinhole, by maintaining a high pressure state, the insulating material in the pinhole can fill the puncture hole more deeply, and reduce the formation of bubbles and gaps. At the same time, it also helps the liquid insulating material to contact the insulating layer of the cable more evenly, thereby improving the adhesion between the two and improving the insulation repair performance of the liquid insulating material after curing.

[0045] In this way, the grounding device can not only realize stripping-free grounding at any position of the wire, but also can perform insulation repair on the pinholes on the wire surface after the grounding work is completed, thereby ensuring the insulation performance of the wire surface layer and reducing safety hazards.

[0046] In one of the more preferred embodiments, an embodiment of a puncture needle and an embodiment of controlling the extension and retraction of the puncture needle are provided;

[0047] The top tube 2 has an inner cavity, and an upper top tube 12 and a lower top tube 13 are slidably mounted in the inner cavity. The upper top tube 12 and the lower top tube 13 can be adjusted to move closer to or farther from each other.

[0048] The puncture needle includes an outer syringe 14 and an inner needle core 15 which are fixedly arranged with each other. The outer syringe 14 is installed at the center of the upper top cylinder 12. The end of the inner needle core 15 is connected to the grounding part through a wire, and the tip parts of the outer syringe 14 and the inner needle core 15 can extend into the needle hole 9 after passing through the lower top cylinder 13. A liquid passage 17 is opened in the center of the lower top cylinder 13 for the outer syringe 14 to pass through.

[0049] For details, please refer to Figure 5 During puncture, the outer needle cylinder 14 and the inner needle core 15 are driven to telescopically move by the mutual approach or distance between the upper and lower top cylinders. When the upper top cylinder 12 and the lower top cylinder 13 are adjusted to approach each other, the upper top cylinder 12 drives the outer needle cylinder 14 and the inner needle core 15 to move downward together, so that the tip parts of the outer needle cylinder 14 and the inner needle core 15 extend from the needle hole 9 to complete the puncture process. Conversely, when the upper top cylinder 12 and the lower top cylinder 13 are adjusted to move away from each other, the upper top cylinder 12 drives the tip parts of the outer needle cylinder 14 and the inner needle core 15 to retract from the needle hole 9 to complete the needle retracting process;

[0050] Furthermore, the liquid passage opened in the center of the lower ejector tube 13 can allow the outer needle tube 14 to pass through and move without affecting its moving stroke.

[0051] In one of the more preferred embodiments, an implementation of a repair portion is provided;

[0052] The repairing part includes a rotating cylinder 11, which is rotatably mounted on the inner wall of the top cylinder 2 between the upper top cylinder 12 and the lower top cylinder 13. The two ends of the rotating cylinder 11 are respectively inserted into the upper top cylinder 12 and the lower top cylinder 13, and are sealed with both. A through hole is opened in the center of the rotating cylinder 11 to connect the upper top cylinder 12 and the lower top cylinder 13. The outer syringe 14 passes through the through hole, and the inner diameter of the through hole is larger than the outer diameter of the outer syringe 14. The upper top cylinder 12 and the lower top cylinder 13 are filled with liquid insulating material.

[0053] A partition 18 extending into the liquid passage 17 is slidably mounted on the outer wall of the outer syringe 14, and a flow gap is provided between the liquid passage 17 and the partition 18. Both ends of the partition 18 are provided with convex ring pieces, and a sealing ring 19 is also fixed on the convex ring piece of the partition 18 located in the space below the lower top cylinder 13.

[0054] For details, please refer to Figure 5As can be seen from the above content, when the upper top tube 12 and the lower top tube 13 are adjusted close to each other, the outer needle tube 14 will extend from the needle hole 9 to complete the puncture process, and at the same time, the lower top tube 13 will move upward. At this time, the liquid insulating material in the upper top tube 12 and the lower top tube 13 will push the partition 18 downward under the action of pressure, so that the sealing ring 19 on the convex ring sheet below the partition 18 is separated from the lower top tube 13, so that the space below the lower top tube 13 is connected with the lower top tube 13, and due to the upward movement of the lower top tube 13, negative pressure will be generated in the space below it, so that the liquid insulating material will flow into the space below through the flow gap between the liquid passage 17 and the partition 18, providing preparation for the subsequent injection of insulating material;

[0055] After the puncture is completed, the upper top cylinder 12 and the lower top cylinder 13 are adjusted away from each other. At this time, the pressure in the space below the lower top cylinder 13 will push the partition 18 upward and close the liquid passage 17. As the lower top cylinder 13 moves downward, the pressure in the space below it gradually increases until the outer syringe 14 is retracted from the needle hole 9 and the space is connected to the outside through the needle hole 9. At this time, the insulating material in the space will be injected into the puncture hole of the wire skin under the action of high pressure, completing the injection of insulating liquid into the puncture hole;

[0056] Furthermore, after the injection, the upper top cylinder 12 and the lower top cylinder 13 are controlled to be adjusted close to each other, and the upper top cylinder 12 will allow the puncture needle to penetrate the needle hole 9 again. However, since the needle hole 9 and the puncture hole are filled with insulating materials at this time, as the puncture needle penetrates, not only can the needle hole 9 be separated into an inner and outer partition so that the insulating materials inside and outside the needle hole 9 do not affect each other, but also the insulating materials inside the needle hole 9 and the puncture hole can be kept in a high pressure state until the solidification process is completed;

[0057] It is worth mentioning that after part of the insulating material in the pinhole 9 and the insulating material in the puncture hole are solidified, after the upper top tube 12 is removed, part of the insulating material in the pinhole 9 can be directly pulled off without affecting the insulating material in the top tube 2, and then the excess insulating material outside the puncture hole can be grinded off.

[0058] It is worth noting that the initial state of the puncture needle in the needle hole 9 is inside the needle hole 9 , which can play a role in sealing the needle hole 9 .

[0059] In this way, through the mutual adjustment between the upper and lower top cylinders, the puncture needle can synchronously drive the internal liquid insulating material to move during the puncture stage and the recovery stage, so as to complete the preparation process before injection and the curing process after injection, thereby improving the overall work efficiency.

[0060] In one of the more preferred embodiments, an implementation method is provided that can control the upper top tube 12 and the lower top tube 13 to move closer to or farther from each other;

[0061] A rotating sleeve 6 is rotatably mounted on the outer wall of the top cylinder 2, and a damping is provided between the rotating sleeve 6 and the outer wall of the top cylinder 2. A connecting shaft 21 is fixed between the inner ring wall of the rotating sleeve 6 and the outer ring wall of the rotating cylinder 11, and a long groove for the horizontal sliding of the connecting shaft 21 is formed in the outer wall of the top cylinder 2. Oblique grooves 23 are formed in the inner walls of the upper top cylinder 12 and the lower top cylinder 13, and the obliquities of the two oblique grooves 23 are opposite. Sliding pins 22 are fixed on the outer walls of the rotating cylinder 11 near both ends, and the two sliding pins 22 are respectively slidably mounted in the two oblique grooves 23.

[0062] Specifically, refer to Figure 8-10 , by manually controlling the rotation of the rotating sleeve 6, the rotating sleeve 6 will drive the rotating cylinder 11 to rotate synchronously through the connecting shaft 21. Since the obliquities of the two oblique grooves 23 are opposite, under the sliding fit between the sliding pins 22 and the oblique grooves 23, the upper and lower top cylinders will approach or move away from each other, thereby achieving the above-mentioned puncturing and repairing purposes;

[0063] Refer to Figure 8 , the upper and lower top cylinders are slidably connected to the inside of the top cylinder 2 through flat keys, which can provide good sliding limits for the upper top cylinder 12 and the lower top cylinder 13. And since a damping is provided between the rotating sleeve 6 and the outer wall of the top cylinder 2, the rotating sleeve 6 can maintain its position after rotation adjustment;

[0064] It should be noted that the rotating sleeve 6 can be controlled by manual rotation, which is more suitable for the case where the insulating skin of the wire is relatively soft and easy to penetrate. It can also be controlled by electric rotation, such as a motor, etc., which is more suitable for the case where the insulating skin of the wire is relatively hard and difficult to penetrate. It can be specifically selected according to the actual situation.

[0065] In one relatively preferred embodiment, a groove for the convex ring piece of the separator 18 to be embedded is formed at the bottom of the lower top cylinder 13. And when the separator 18 is embedded in the groove, the bottom surface of the separator 18 is flush with the bottom surface of the lower top cylinder 13. A protrusion 24 for limiting the separator 18 is provided at the inner bottom of the lower top cylinder 13.

[0066] Refer to Fig.10 , the setting of the groove at the bottom surface of the lower top cylinder 13 can prevent the separator 18 from affecting the moving stroke of the lower top cylinder 13. At the same time, the setting of the protrusion 24 can prevent the convex ring piece at the top of the separator 18 from directly closing the liquid passing channel 17, ensuring the connection of the liquid passing channel 17 when the lower top cylinder 13 moves upward, so as to ensure that the insulating material flows into the lower space after pushing the separator 18 open.

[0067] In one relatively preferred embodiment, a liquid replenishing pipe 7 is also communicated with the inner top of the upper top cylinder 12. The liquid replenishing pipe 7 penetrates out of the U-shaped frame 1 and is connected to an external liquid supply device, and a one-way valve that can only suck the liquid into the upper top cylinder 12 is installed in the liquid replenishing pipe 7.

[0068] Liquid insulating material can be added to the space between the upper top tube 12 and the lower top tube 13 through the liquid filling tube 7, and the liquid filling operation can be performed without disassembling them.

[0069] In one of the more preferred embodiments, the outlet position of the pinhole 9 is set as an outward expansion opening 16, and the outward expansion opening 16 is cone-shaped, and the cone surface expands from the inside to the outside.

[0070] Since the aperture of the puncture hole is the same as that of the pinhole 9, only the puncture hole is filled after the insulating material is solidified. During the use of the wire, the insulating material in the puncture hole is easily separated from the puncture hole under the action of mechanical stress. Therefore, in order to further ensure the stability of the insulating material in the puncture hole after solidification, the outlet position of the pinhole 9 is set to the outer expansion 16. For details, please refer to Figure 5 In this way, after the insulating material solidifies at the puncture hole, after the top tube 2 is detached, a small protrusion will be formed on the outermost layer of the insulating material at the puncture hole, and the small protrusion will adhere to the surface of the wire near the puncture hole. The specific form can be referred to as the pin. In this way, through the adhesion between the small protrusion and the surface of the wire, the insulating material in the puncture hole can still maintain the sealing effect on the puncture hole when subjected to mechanical stress, thereby ensuring its insulation performance during subsequent use.

[0071] In one of the more preferred embodiments, the outer needle cylinder 14 is rotatably installed at the center position of the upper top cylinder 12, and a limiting slide bar 20 is fixed to the outer wall of the outer needle cylinder 14 located in the central through hole of the rotating cylinder 11, and the limiting slide bar 20 and the inner wall of the through hole in the center of the rotating cylinder 11 slide vertically to limit.

[0072] See also Figure 5 and Figure 8 As can be seen from the previous content, the puncture needle completes the puncture process by moving the upper top cylinder 12, and the movement of the upper and lower top cylinders is driven by the rotation of the rotating sleeve 6. Therefore, during the rotation of the rotating sleeve 6, the rotating cylinder 11 will also rotate synchronously. When the limiting slide bar 20 slides in the lower position, the outer needle cylinder 14 (i.e., the puncture needle) can rotate with the rotating cylinder 11 when moving, so that the puncture needle is in a rotating state during puncture and retraction. Compared with the straight puncture method, this can make the puncture needle easier to pierce the insulation skin of the wire, thereby effectively improving its puncture efficiency.

[0073] In one of the more preferred embodiments, an implementation of a clamping portion is provided;

[0074] The clamping part includes a clamping block 3 slidably mounted on the inner wall of the top cylinder 2, and an arc groove for the wire to be inserted is provided on the top surface of the clamping block 3. A screw rod 4 is installed through the bottom of the frame of the U-shaped frame 1, and the screw rod 4 is threadedly connected to the through hole at the bottom of the frame of the U-shaped frame 1. The top end of the screw rod 4 is rotatably connected to the bottom of the clamping block 3. The grounding part includes a grounding rod 5 connected to the bottom end of the screw rod 4.

[0075] Specifically, it can be seen Figure 8 , by rotating the grounding rod 5, the clamping block 3 can be driven by the screw rod 4 to slide within the U-shaped frame 1, so as to cooperate with the top cylinder 2 to complete the clamping and fixing of the wire, and then the grounding rod 5 can be inserted into the ground to complete the grounding process.

[0076] In one relatively preferred embodiment, an acoustic-optic alarm device 10 for monitoring the current between the puncture needle and the grounding part is further installed on the outer wall of the U-shaped frame 1.

[0077] The acoustic-optic alarm device 10 can detect the current in the circuit. When there is current in the circuit, it will send out an alarm message and record it. The virtual connection between the grounding rod and the wire can be determined by resistance detection. When it is determined that there is a virtual grounding connection, the main controller will remind the operator to pay attention to safety through the optical alarm device;

[0078] Moreover, the acoustic-optic alarm device 10 is composed of a high-brightness LED and a high-power horn. When there is current in the circuit or poor grounding mounting is detected, it will remind the operator through the horn and the red warning light. When there is no current in the circuit and the grounding mounting is good, it will remind the operator to continue the operation through the green indicator light.

[0079] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed according to the existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0080] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
