Description

Technical Field

[0001] The invention relates to the technical field of power equipment protection, and in particular to an insulation safety protection device for a high-voltage line. Background Art

[0002] Under the background of the rapid expansion and iterative upgrade of the current power network, the laying scope of high-voltage transmission lines is expanding day by day, and with it comes increasingly severe challenges of external force damage, including but not limited to accidental contact during construction, direct impact of extreme weather, etc. Therefore, the development of efficient safety protection devices has become the key to ensuring the safe operation of high-voltage lines.

[0003] Traditional high-voltage line insulation safety protection technology mainly controls the horizontal displacement of the insulating rod through a driving mechanism, and then pulls the mesh insulating rope connected to the end of the insulating rod to unfold and arrange. This design strategy aims to build a physical barrier in the target protection area. When the insulating rope is accurately positioned to the predetermined protection point, the driving system continues to drive the insulating rod to a predetermined height to ensure that the mesh insulating rope can be fully spread and effectively cover the key protection area of ​​the high-voltage line. This device effectively prevents wild animals or people from mistakenly entering the vicinity of high-voltage lines through physical barriers, significantly reducing the risk of electric shock caused by direct contact, and effectively ensuring the stable operation of power facilities and public safety.

[0004] However, in actual deployment, especially in outdoor environments, the stability and protective effectiveness of the mesh insulating rope face the test of many external factors. Especially under strong wind conditions, the wind directly acts on the mesh insulating rope, which can easily cause it to shift in position or even swing violently. This dynamic change induced by wind may not only destroy the original precise protection layout of the insulating rope, but also cause an imbalance in the internal tension distribution of the insulating rope due to the continuous non-uniform action of wind, and tension attenuation in some areas. Insufficient tension directly weakens the structural stability and impact resistance of the mesh insulating rope, thereby reducing the effective protection level of high-voltage lines and increasing the risk of safety accidents.

[0039] Please also refer to Figures 1 to 8 As shown, an embodiment of the present invention provides an insulation safety protection device for a high voltage line, comprising:

[0040] A plurality of first insulating rods 1, the bottom ends of which are fixedly mounted with a first driving assembly 3; the output end of the first driving assembly 3 extends into the interior of the first insulating rod 1, and is fixedly mounted with a threaded rod 4;

[0041] A plurality of second insulating rods 2 are respectively slidably connected in the corresponding first insulating rods 1 and threadedly connected to the threaded rods 4;

[0042] The adjusting mechanism is arranged at the top end of each of the second insulating rods 2, and includes a mounting shell 5, a winch 6 arranged inside the mounting shell 5, a mesh insulating rope 7 wound on the surface of the winch 6, and a fixing component for fixing the mesh insulating rope 7, wherein the fixing component is used to clamp or release the mesh insulating rope 7 in response to external drive.

[0043] Specifically, in the embodiment of the present invention, the number of the first insulating rod 1 and the second insulating rod 2 are both four, and each two form a group. The bottom end of the first insulating rod 1 is fixedly installed with a first driving assembly 3, the output end of the first driving assembly 3 extends to the inside of the first insulating rod 1, and a threaded rod 4 located inside the second insulating rod 2 is fixedly installed, and the threaded rod 4 is threadedly connected to the second insulating rod 2. One end of the mesh insulating rope 7 passes through the inner wall of the mounting shell 5 and is fixedly connected to the second insulating rod 2 away from the surface of the mounting shell 5. A spring 8 is fixedly installed inside the mounting shell 5, and a plug plate 9 located at the top of the mesh insulating rope 7 is fixedly installed at the bottom end of the spring 8. A slot 10 located at the bottom end of the plug plate 9 is opened inside the mounting shell 5, and a fixed block 11 is fixedly installed in the middle of the top of the plug plate 9. An extrusion block 12 is slidably connected inside the mounting shell 5, and a rack 15 is fixedly installed on the side of the extrusion block 12 away from the surface of the fixed block 11. A first motor 13 is fixedly installed in the inner cavity of the mounting shell 5, and a first gear 14 meshing with the rack 15 is fixedly installed at the output end of the first motor 13.

[0044] According to the above structural arrangement, the operator drives the winch 6 to rotate, and then the mesh insulating rope 7 wound on the surface of the winch 6 will be detached, and then the second insulating rod 2 and the first insulating rod 1 away from the surface of the mounting shell 5 can be pushed to move. During the movement, the mesh insulating rope 7 will be pulled to move. When the mesh insulating rope 7 is pulled out to a specified length, the first driving assembly 3 can be driven to rotate the threaded rod 4. Since the threaded rod 4 is threadedly connected to the second insulating rod 2, when the threaded rod 4 rotates, the second insulating rod 2 will move on the surface of the threaded rod 4, and then the second insulating rod 2 will push the mounting shell 5 and the mesh insulating rope 7 to rise, and the adjustment range covers up to ten meters. Then the mesh insulating rope 7 can be moved to a specified height, and then the mesh insulating rope 7 can be used to block and protect animals or people to prevent them from contacting the surface of the high-voltage line.

[0045] During the operation of the mesh insulating rope 7, the first motor 13 can be driven to rotate the first gear 14, because the first gear 14 is meshed with the rack 15, and then when the first gear 14 rotates, the rack 15 will be driven to move, and the rack 15 will push the extrusion block 12 to move, and then one side of the extrusion block 12 will contact the surface of the fixed block 11, and will squeeze the fixed block 11 to move downward, and the fixed block 11 will push the plug plate 9 down, and when the plug plate 9 is lowered, the spring 8 will be stretched, and then the bottom end of the plug plate 9 will contact the surface of the mesh insulating rope 7, and will push the mesh insulating rope 7 into the plug plate. The inside of the slot 10, and then the plug plate 9 can fix the mesh insulating rope 7, and finally the plug plate 9 fixes the mesh insulating rope 7 by driving the first motor 13, so that the insulation distance between the mesh insulating rope 7 and the high-voltage line is maintained, effectively blocking the contact between animals and humans and the high-voltage line, and reducing the risk of high-voltage line short circuit or electric shock accidents caused by animal activities or human misoperation. When the mesh insulating rope 7 enters the inside of the slot 10, the tension of the mesh insulating rope 7 can be increased, so that the mesh insulating rope 7 has stronger resistance to external factors, thereby improving the safety protection level of the high-voltage line.

[0046] like Figure 6 and Figure 7As shown, an insulation safety protection device for a high-voltage line in an embodiment of the present invention also includes: a fixing mechanism, which is arranged on a side of the second insulating rod 2 close to the mesh insulating rope 7, the fixing mechanism includes a connecting shell 16, the connecting shell 16 is fixedly connected to the side of the second insulating rod 2 close to the mesh insulating rope 7, the inner cavity of the connecting shell 16 is provided with a limit rod 17, the surface of the limit rod 17 is slidably connected to a connecting plate 18, the bottom end of the connecting plate 18 is fixedly installed with a ground plug 19, the inner cavity of the connecting shell 16 is fixedly installed with a slide rail 20, the surface of the slide rail 20 is slidably connected to two sliders 21, the top of the ground plug 19 is fixedly installed with a hinge block 22, the two sliders 21 are hinged to the hinge block 22 through a hinge rod 23, the inner cavity of the connecting shell 16 is fixedly installed with a second motor 24 located at the top of the slide rail 20, the output end of the second motor 24 is fixedly installed with a bidirectional screw rod 25, the surface of the bidirectional screw rod 25 is threadedly connected to two threaded plates 26, and the bottom ends of the two threaded plates 26 are fixedly connected to the two sliders 21.

[0047] According to the above structural arrangement, through the design of the fixing mechanism, when the device needs to be fixed, the second motor 24 can be driven to rotate the bidirectional screw rod 25. Since the bidirectional screw rod 25 is threadedly connected with the threaded plate 26, when the bidirectional screw rod 25 rotates, the two threaded plates 26 will move relative to each other on the surface of the bidirectional screw rod 25, and the threaded plate 26 will drive the slider 21 to move relative to each other. Since the slider 21 is hinged to the hinge block 22 through the hinge rod 23, when the slider 21 moves, it will push the hinge rod 23 to rotate. During the rotation of the hinge rod 23, the hinge rod 23 will rotate. During the process, the hinge block 22 will be pushed down, and the hinge block 22 will push the ground plug 19 to move. When the ground plug 19 moves, the connecting plate 18 will move on the surface of the limiting rod 17, and then the limiting rod 17 can limit the connecting plate 18 and the ground plug 19. Then the ground plug 19 will be inserted into the ground, and then the whole device can be fixed. Finally, the two-way screw rod 25 is driven to make the hinge rod 23 push the ground plug 19 to be inserted into the ground, and then the whole device can be fixed without using fixing bolts, thereby increasing the convenience of device installation.

[0048] like Figure 4 As shown, a fixing plate 27 is fixedly installed in the inner cavity of the mounting shell 5, and limiting grooves 28 are provided on both sides of the outer surface of the fixing plate 27. The inner part of the limiting groove 28 is slidably connected to a limiting block 29, and the bottom end of the limiting block 29 is fixedly connected to the top end of the extrusion block 12.

[0049] According to the above structural arrangement, through the design of the fixed plate 27, the limiting groove 28 and the limiting block 29, when the rack 15 pushes the extrusion block 12 to move, the extrusion block 12 will drive the limiting block 29 inside the limiting groove 28, and then the fixed plate 27 can support and limit the limiting block 29, thereby ensuring that the extrusion block 12 can move normally.

[0050] like Figure 1 and Figure 2 As shown, a plurality of rollers 30 are fixedly mounted on the bottom end of the first insulating rod 1 , with four rollers 30 forming a group and located at the bottom end of the first insulating rod 1 . A sealing groove 31 is formed at the top end of the mounting shell 5 , and a sealing plate 32 is inserted into the sealing groove 31 .

[0051] According to the above structural arrangement, through the design of the roller 30, when the first insulating rod 1 and the second insulating rod 2 are pushed, the roller 30 will rotate, so that the roller 30 can drive the first insulating rod 1 and the second insulating rod 2 to move, and the rollers 30 are grouped into four, which can ensure the stability of the movement of the first insulating rod 1 and the second insulating rod 2. Through the design of the sealing groove 31 and the sealing plate 32, when it is necessary to replace the capstan 6 and the mesh insulating rope 7 of different sizes, the sealing plate 32 can be pulled out from the inside of the sealing groove 31, and then the capstan 6 and the mesh insulating rope 7 inside the mounting shell 5 will be exposed, and then they can be replaced.

[0052] like Figure 5 and Figure 8 As shown, a square plate 33 located inside the second insulating rod 2 is fixedly mounted on the bottom end of the mounting shell 5, and a plug hole 34 is provided on the surface of the mounting shell 5 and the square plate 33. A plug pin 35 is inserted into the plug hole 34, and a protrusion 36 is fixedly mounted on the surface of the plug pin 35.

[0053] According to the above structural arrangement, through the design of the pin 35 and the protrusion 36, when the winch 6 and the mesh insulating rope 7 need to be replaced, the pin 35 and the protrusion 36 can be rotated to align the protrusion 36 with the socket 34, and then the pin 35 and the protrusion 36 can be taken out from the inside of the socket 34, and then the inside of the square plate 33 can be cancelled, so that the mounting shell 5 can be removed from the top of the second insulating rod 2. After the winch 6 and the mesh insulating rope 7 are replaced, the mounting shell 5 can be placed on the top of the second insulating rod 2 again, and the socket 34 can be inserted into the inside of the second insulating rod 2, and then the two sockets 34 will overlap, and then the pin 35 and the protrusion 36 can be inserted into the inside of the socket 34 again, and then when the protrusion 36 passes through the socket 34, the pin 35 and the protrusion 36 can be rotated to make it misaligned with the socket 34, so that the mounting shell 5 can be fixed on the top of the second insulating rod 2 again.

[0054] like Figure 1 , Figure 6 and Figure 7 As shown, both sides of the surface of the slide rail 20 are provided with slide grooves 37, the internal rotation of the slider 21 is connected to a pulley 38 located inside the slide groove 37, a monitoring component 39 is provided at the top of the mounting shell 5, and an alarm 40 located on one side of the monitoring component 39 is fixedly installed at the top of the mounting shell 5.

[0055] According to the above-mentioned structural arrangement, through the design of the slide groove 37 and the pulley 38, since the surface of the pulley 38 contacts the inner wall of the slide groove 37, when the slider 21 moves, the pulley 38 will rotate inside the slide groove 37, so that the slider 21 can move more smoothly. Through the design of the monitoring component 39 and the alarm 40, when the mesh insulating rope 7 is broken during protection, the mesh insulating rope 7 will swing violently, and the monitoring component 39 will detect the amplitude of the swing, and then the alarm 40 will sound an alarm to remind the operator.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, the side opposite to the extrusion block 12 and the fixing block 11 is designed as an inclined surface, and the two inclined surfaces are designed to be parallel. The surface of the mesh insulating rope 7 is provided with a colored ribbon. The total length of the mesh insulating rope 7 is ten meters, and a section of the colored ribbon is provided every two meters.

[0057] According to the above structural arrangement, through the design of the fixed block 11 and the extrusion block 12, since the side opposite to the fixed block 11 of the extrusion block 12 is designed as an inclined surface and parallel to each other, it is convenient for the extrusion block 12 to squeeze the fixed block 11 down, and through the design of the mesh insulating rope 7, since a colored identification tape should be set every two meters on the mesh insulating rope 7, it can improve visibility and prevent it from hanging on the high-voltage line after breaking.

[0058] The working principle and use process of the present invention are as follows:

[0059] First, the operator can drive the winch 6 to rotate to disengage the mesh insulating rope 7, and then push the second insulating rod 2 and the first insulating rod 1 away from the surface of the mounting shell 5 to move. When the mesh insulating rope 7 is pulled out to a specified length, the second motor 24 can be driven to rotate the bidirectional screw rod 25. The two threaded plates 26 will move relative to each other on the surface of the bidirectional screw rod 25. The threaded plates 26 will drive the slider 21 to move relative to each other. The slider 21 will push the hinge rod 23 to rotate. During the rotation of the hinge rod 23, the hinge block 22 will be pushed down, and the hinge block 22 will push the connecting plate 18 and the ground plug 19. The connecting plate 18 moves on the surface of the limiting rod 17, thereby limiting the connection plate 18 and the ground plug 19, and then the ground plug 19 is inserted into the ground, thereby fixing the entire device; after the fixing is completed, the first driving component 3 can be driven to rotate the threaded rod 4, and the second insulating rod 2 can move on the surface of the threaded rod 4, and the second insulating rod 2 can push the mounting shell 5 and the mesh insulating rope 7 to rise, and then the mesh insulating rope 7 is moved to a specified height, thereby enabling the mesh insulating rope 7 to block and protect animals or people from contacting the surface of the high-voltage line;

[0060] During the operation of the mesh insulating rope 7, the first motor 13 can be driven to rotate the first gear 14, and the first gear 14 will drive the rack 15 to move, and the rack 15 will push the extrusion block 12 and the limit block 29 to move, and the limit block 29 can limit and support the extrusion block 12, and then one side of the extrusion block 12 will contact the surface of the fixed block 11, and will squeeze the fixed block 11 and the plug plate 9 to move downward, when the plug plate 9 descends, the spring 8 will be stretched, and the plug plate 9 will push the mesh insulating rope 7 into the inside of the slot 10, and then the plug plate 9 can fix the mesh insulating rope 7, and increase the tension of the mesh insulating rope 7, so that the mesh insulating rope 7 has stronger resistance to external factors, and finally completes the operation process.

[0061] It can be seen from the above description that compared with the prior art, the beneficial effect brought by the embodiment of the present invention is that the present invention realizes effective safety protection and convenient installation of high-voltage lines through innovative mechanical structure design. The first motor is driven to make the first gear drive the rack to move, so that the extrusion block pushes the plug plate to firmly fix the mesh insulating rope in the slot, maintains the insulation distance, effectively prevents animals or people from accidentally touching the high-voltage line, reduces the risk of short circuit and electric shock, and increases the tension of the mesh insulating rope, thereby improving the protection level. At the same time, the second motor is driven to rotate the bidirectional screw rod, and the ground plug is firmly inserted into the ground through the clever cooperation of the threaded plate, the slider and the articulated rod. The device can be quickly fixed without fixing bolts, which greatly improves the convenience and flexibility of installation. The present invention not only enhances the safety protection capability of high-voltage lines, but also simplifies the installation process and reduces the installation cost. It is of great significance to improve the safety and maintenance efficiency of power facilities, and provides an efficient and reliable solution for the safety protection of the power industry.

[0062] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
