Description

Technical Field

[0001] The present invention relates to the technical field of electronic fences, and in particular to an electronic fence auxiliary device for a substation. Background Art

[0002] Under the background of rapid development of the power industry, substations, as the core components of the power system, have become the focus of industry attention for their safety and stability. Traditional substation fences are mostly solid walls or metal fences, facing challenges such as complex installation, high maintenance costs and limited protection, especially in extreme weather, which are easily damaged and affect the operation of substations.

[0003] In view of the above problems, the existing technology innovatively proposes a solution to embed the cables inside the electric fence pillars. The purpose is to effectively isolate the intrusion of the harsh external environment by installing the cables inside, and simultaneously improve the overall protection efficiency of the fence. However, this also causes new problems: once the cables become loose, it is difficult for the staff to perform effective tensioning and fixing operations due to space limitations.

[0004] Therefore, how to ensure that the cables are protected from interference from the external environment while facilitating their tensioning and maintenance has become a key issue that needs to be urgently addressed in the current substation electronic fence design. In response to the above situation, we provide a substation electronic fence auxiliary device to solve the above problem. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an electronic fence auxiliary device for a substation, which cleverly designs a hollow pillar, and is equipped with an extrusion device and a support block to achieve online tensioning and fixation of the cables inside the pillar. While being suitable for various harsh environments, it ensures that the cables always remain taut, solving the problem of cable looseness.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts an electronic fence auxiliary device for a substation, comprising:

[0007] A support column, which is vertical, has a hollow interior and a rectangular sliding space;

[0008] A crossbeam, the crossbeam being installed between two adjacent pillars, and the number of the crossbeams installed between two adjacent pillars is at least one;

[0009] A cable, part of which is located inside the sliding space and both ends of which extend outward and deep into the crossbeam, and both sides of the support are provided with inlets parallel to the crossbeam for the cable to pass through;

[0010] The locking member is affixed to the locking cam which is secured to the locking cam by the locking cam and is adapted to engage the locking cam of the locking cam.

[0011] A support block is located inside the sliding space and has a support surface for supporting the cable, and the support surface is arranged corresponding to the top surface of the sliding and pressing member.

[0012] The above structure cleverly designs the pillar as a vertical hollow structure, and matches it with an extrusion device and a support block. Through the rotation of the rotating rod, the rotation of the connecting rod and the sliding rod is realized, thereby realizing the downward movement of the above-mentioned sliding and pressing part. Then, through the downward movement of the sliding and pressing part, the online extrusion and fixation of the cables inside the pillar is realized. While being suitable for various harsh environments, it ensures that the cables are always kept taut, solving the problem of loose cables.

[0013] As a further optimization of the above solution, the support surface is provided with a first magnetic block, the extrusion device is provided with a second magnetic block corresponding to the position on the support surface, and the first magnetic block and the second magnetic block are magnetically matched. The second magnetic block is provided with a groove for the first magnetic block to be provided with a matching structure with the first magnetic block. By designing the first magnetic block and the second magnetic block to be magnetically matched, the cooperation between the above sliding and pressing member and the support block can better extrude and fix the cable, thereby improving the cable tightening effect.

[0014] As a further optimization of the above scheme, a shell is also provided above the sliding and pressing part, a first magnet is provided at the bottom of the shell, and a second magnet is provided above the sliding and pressing part. The first magnet and the second magnet are magnetically repelled, and the extrusion part is located at the upper part of the above shell. By utilizing the principle of magnetic repulsion, an indirect extrusion structure between the sliding and pressing part and the shell is constructed to prevent the sliding and pressing part from causing cable damage due to rapid sliding and pressing.

[0015] As a further optimization of the above scheme, an extrusion block is provided at the center of the sliding member, the second magnet is located on both sides of the extrusion block, and a buffer air bag is provided inside the shell, and the buffer air bag is located on the extrusion path of the extrusion block. Through the setting of the buffer air bag, the falling speed of the sliding member is further buffered to prevent the extrusion block from falling too fast.

[0016] As a further optimization of the above scheme, there is a gap between the buffer airbag and the extrusion block, strip blocks are provided on both sides of the cable and the bottom surface of the strip block is laid on the supporting surface, a moving space is provided inside the strip block, a pushing airbag is provided inside the moving space, the pushing airbag is connected with the buffer airbag and the buffer airbag is inflated toward the pushing airbag after being squeezed by external force, a moving rod is provided on the outside of the pushing airbag, the outer end of the moving rod extends out of the moving space and is connected to a connecting piece, a gear is rotatably connected to the connecting piece, a first rack laid on the supporting surface is provided below the gear and the first rack is meshed with the above gear, a second rack meshed with the gear is provided above the gear, a pressurizing portion is provided on the end of the second rack facing the cable, and the pressurizing portion is an arc shape that fits the outer surface of the cable.

[0017] This structural design gives the sliding part two usage states: in the first state, the sliding part uses the principle of magnetic repulsion to achieve indirect extrusion and provide repulsion for the shell. This mechanism effectively reduces the direct compression damage to the cable; in the second state, after the sliding part is pressed down a certain distance, it gradually contacts and compresses the buffer airbag. The buffer airbag not only slows down the downward speed of the sliding part, but also realizes the slow inflation of the push airbag to prevent it from moving quickly. At this time, the push airbag drives the connecting part to move in a straight line, driving the gear to move in a straight line along the first rack. The rotational movement of the gear then drives the second rack to move, so that the pressure part on it is close to the side of the cable, realizing the extrusion and fixation of the cable in the vertical and lateral directions. This four-way extrusion and fixation mechanism ensures that the cable is in a straight state, greatly reducing the possibility of cable loosening.

[0018] As a further optimization of the above solution, the housing is further provided with a supporting airbag located below the cable, and the buffer airbag has two connecting channels, and the two connecting channels are respectively connected to the pushing airbag and the supporting airbag. This structural design gives the buffer airbag an additional function, that is, it can inflate the supporting airbag. The buffer airbag slowly inflates the supporting airbag, thereby gradually lifting the bottom of the cable and tightening the cable, further causing the cable to be in a straight state, and effectively improving the fixing effect of the cable.

[0020] The electronic fence auxiliary device for a substation of the present invention has the following beneficial effects:

[0021] 1. The electronic fence auxiliary device for a substation of the present invention cleverly designs the pillar into a vertical hollow structure, and is matched with an extrusion device and a support block. The rotation of the rotating rod realizes the rotation of the connecting rod and the sliding rod, thereby realizing the downward movement of the above-mentioned sliding pressure member, and then through the downward movement of the sliding pressure member, the online extrusion and fixation of the cables inside the pillar is realized. It is suitable for various harsh environments and ensures that the cables are always kept in a taut state, solving the problem of cable looseness.

[0022] 2. The electronic fence auxiliary device for a substation of the present invention utilizes the principle of magnetic repulsion to construct an indirect extrusion structure between the sliding and pressing member and the shell to prevent the sliding and pressing member from causing cable pressure loss due to rapid sliding pressure.

An electronic fence auxiliary device for a substation of the present invention gives the sliding pressure piece two usage states: in the first state, the sliding pressure piece realizes indirect extrusion by utilizing the principle of magnetic repulsion, providing repulsion for the shell, and this mechanism effectively reduces the direct compression damage to the cable; in the second state, after the sliding pressure piece is pressed down a certain distance, it gradually contacts and compresses the buffer airbag. The buffer airbag not only slows down the downward speed of the sliding pressure piece, but also realizes the slow inflation of the pushing airbag to prevent it from moving quickly. At this time, the pushing airbag drives the connecting piece to move in a straight line, driving the gear to move in a straight line along the first rack. The rotational movement of the gear then drives the second rack to move, so that the pressure-applying part on it is close to the side of the cable, realizing the extrusion and fixation of the cable in the vertical and lateral directions. This four-way extrusion and fixation mechanism ensures that the cable is in a straight state, greatly reducing the possibility of cable loosening.

The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] Please refer to the instruction manual Figure 1-8 The present invention provides a first embodiment of an electronic fence auxiliary device for a substation. In the first embodiment, the electronic fence is mainly composed of a vertical pillar 1, a beam 2, a cable 3, an extrusion device 4 and a support block 5. The pillar 1 is designed as a vertical hollow structure with a rectangular sliding space inside. The beam 2 is installed between two adjacent pillars 1, and at least one beam 2 is installed between each pair of adjacent pillars 1. Part of the cable 3 is located inside the sliding space, and both ends extend outward and deep into the beam 2. Both sides of the pillar 1 are provided with an inlet parallel to the beam 2 for the cable 3 to pass through.

[0039] The extrusion device 4 includes a rotating rod 41, a connecting rod 42, a first locking hole 43, a second locking hole 44, a locking member 45, an arc hole 46, a sliding member 47, a sliding hole 48 and a sliding rod 49. The outer surface of the pillar 1 is rotatably connected with the rotating rod 41, and the outer circumferential surface of the rotating rod 41 is fixedly connected with the connecting rod 42, so that the connecting rod 42 can rotate together with the rotating rod 41. The connecting rod 42 is provided with a first locking hole 43, and the pillar 1 is provided with two second locking holes 44 corresponding to the position of the first locking hole 43, and the two second locking holes 44 are located near the two ends of the arc hole 46 opened on the pillar 1. The locking member 45 passes through the first locking hole 43 and the second locking hole 44, and is used to lock the position of the connecting rod 42. The sliding member 47 is slidably connected in the sliding space, and the cable 3 is located on the moving path of the sliding member 47. A strip-shaped sliding groove is provided on one side of the sliding member 47 facing the arc-shaped hole 46, and a sliding rod 49 is connected to the connecting rod 42, and one end of the sliding rod 49 is inserted into the strip-shaped sliding groove. When the rotating rod 41 rotates, the connecting rod 42 and the sliding rod 49 are driven to rotate together, and the sliding rod 49 slides along the arc-shaped hole 46, thereby driving the sliding member 47 to slide and move.

[0040] The support block 5 is located inside the sliding space and has a support surface 51 for supporting the cable 3. The support surface 51 is arranged corresponding to the top surface of the sliding and pressing member 47. When the sliding and pressing member 47 moves downward, the cable 3 on the support surface 51 is squeezed and fixed.

[0041] As a further possible improvement of the above scheme, in some embodiments, a first magnetic block 52 is provided on the support surface 51, and a second magnetic block 6 corresponding to the position on the support surface 51 is provided on the extrusion device 4. The two magnetic blocks are designed to be magnetically matched, that is, the first magnetic block 52 and the second magnetic block 6 can attract each other. In order to achieve a more stable magnetic match, the second magnetic block 6 is provided with a groove 471 structure that matches the first magnetic block 52. This magnetic match design enables the sliding member 47 and the support block 5 to better squeeze and fix the cable 3 when they are matched, thereby improving the fastening effect of the cable 3.

[0042] In summary, the ingenious design of this embodiment realizes the rotation of the rotating rod 41 to drive the rotation of the connecting rod 42 and the sliding rod 49, thereby realizing the downward movement of the sliding member 47. This design enables the cable 3 inside the support 1 to be squeezed and fixed online, which is not only suitable for various harsh environments, but also ensures that the cable 3 is always kept in a taut state, effectively solving the problem of cable 3 loosening.

[0043] Please refer to the instruction manual Figure 1-8 The present invention provides a second embodiment of an electronic fence auxiliary device for a substation. Based on the structure of the first embodiment, the second embodiment further improves the electronic fence structure and focuses on improving the sliding member 47 to achieve flexible extrusion fixation of the cable 3. At the same time, it achieves multi-directional fixation of the cable 3 to ensure that the cable 3 is in a straight state during the fixing process. The specific structure of the second embodiment is as follows:

[0044] This embodiment includes the following structures:

[0045] A support column 1, wherein the support column 1 is vertical, the interior of the support column 1 is hollow, and a rectangular sliding space is reserved;

[0046] A crossbeam 2, wherein the crossbeam 2 is installed between two adjacent pillars 1, and the number of crossbeams 2 installed between two adjacent pillars 1 is at least one;

[0047] The cable 3 is partially located in the sliding space and its two ends extend outward and deep into the cross beam 2. Both sides of the support 1 are provided with inlets parallel to the cross beam 2 and for the cable 3 to pass through;

[0048] The extrusion device 4 includes a rotating rod 41, a connecting rod 42, a first locking hole 43, a second locking hole 44, a locking member 45, an arc hole 46, a sliding member 47, a sliding hole 48 and a sliding rod 49. The outer surface of the pillar 1 is rotatably connected to the rotating rod 41, and the outer circumferential surface of the rotating rod 41 is fixedly connected to the connecting rod 42 so that the connecting rod 42 rotates with the rotating rod 41. The connecting rod 42 is provided with a first locking hole 43, and the pillar 1 is provided with a second locking hole 44 corresponding to the position of the first locking hole 43. The locking member 45 passes through the first locking hole 43 and the second locking hole 44. The locking hole 44 is used to lock the position of the connecting rod 42. An arc-shaped hole 46 is provided on the pillar 1. The number of the second locking holes 44 is two and they are located near the two ends of the arc-shaped hole 46. A sliding member 47 is slidably connected in the sliding space. The cable 3 is located on the moving path of the sliding member 47. The sliding member 47 is provided with a strip sliding groove on one side facing the arc-shaped hole 46. A sliding rod 49 is connected to the connecting rod 42 and one end of the sliding rod 49 penetrates into the interior of the strip sliding groove. The sliding rod 49 drives the sliding member 47 to slide and move during the sliding process along the arc-shaped groove.

[0049] The support block 5 is located inside the sliding space and has a support surface 51 for supporting the cable 3 . The support surface 51 is arranged corresponding to the top surface of the sliding and pressing member 47 .

[0050] The above structure cleverly designs the pillar 1 as a vertical hollow structure, and matches it with the extrusion device 4 and the support block 5. Through the rotation of the rotating rod 41, the rotation of the connecting rod 42 and the sliding rod 49 is realized, thereby realizing the downward movement of the above-mentioned sliding and pressing member 47. Then, through the downward movement of the sliding and pressing member 47, the online extrusion and fixation of the cable 3 inside the pillar 1 is realized. While being suitable for various harsh environments, it ensures that the cable 3 always remains taut, solving the problem of cable 3 loosening.

[0051] A housing 7 is provided above the sliding member 47, a first magnet 71 is installed at the bottom of the housing 7, and a second magnet 472 is provided above the sliding member 47. The two magnets are designed to repel each other magnetically, that is, a repulsive force is generated between them. The extrusion portion 72 is located at the upper part of the housing 7, and an indirect extrusion structure between the sliding member 47 and the housing 7 is constructed by using the principle of magnetic repulsion, which effectively prevents the sliding member 47 from causing pressure damage to the cable 3 due to rapid sliding pressure.

[0052] Further preferably, an extrusion block 473 is provided at the center of the sliding member 47, and the second magnet 472 is located on both sides of the extrusion block 473. A buffer airbag 73 is also provided inside the housing 7, and the airbag is located on the extrusion path of the extrusion block 473. When the sliding member 47 falls, the buffer airbag 73 can play a buffering role, further slowing down the falling speed of the sliding member 47, thereby preventing the extrusion block 473 from falling too quickly and causing damage to the cable 3.

[0053] Further preferably, a certain gap is maintained between the buffer airbag 73 and the extrusion block 473. Bar blocks 8 are provided on both sides of the cable 3, and the bottom surface of the bar blocks 8 is laid on the support surface 51. A moving space 81 is provided inside the bar block 8, and a pushing airbag 82 is installed in the moving space 81. The pushing airbag 82 is connected to the buffer airbag 73, and when the buffer airbag 73 is squeezed by an external force, it will inflate the pushing airbag 82. A moving rod 83 is provided on the outside of the pushing airbag 82, and the outer end of the moving rod 83 extends out of the moving space 81 and is connected to a connecting member 84. A gear 85 is rotatably connected to the connecting member 84, and a first rack 86 laid on the support surface 51 is provided below the gear 85, and the gear 85 is meshed with the first rack 86. A second rack 87 meshing with the gear 85 is disposed above the gear 85 . A pressurizing portion 88 is disposed at one end of the second rack 87 facing the cable 3 . The pressurizing portion 88 is designed to be in an arc shape that fits the outer surface of the cable 3 .

[0054] The above structural design gives the sliding member 47 two usage states: in the first state, the sliding member 47 realizes indirect extrusion by using the principle of magnetic repulsion, provides repulsion force for the shell 7, and effectively reduces the direct compression damage to the cable 3; in the second state, when the sliding member 47 is pressed down a certain distance, it will gradually contact and compress the buffer airbag 73, which slows down the pressing speed of the sliding member 47 on the one hand; on the other hand, it realizes the slow inflation of the push airbag 82, thereby preventing it from moving quickly. At this time, the push airbag 82 will drive the connecting member 84 to move linearly, and then drive the gear 85 to move linearly along the first rack 86. The rotational movement of the gear 85 will push the second rack 87 to move, so that the pressure part 88 on the second rack 87 is close to the side of the cable 3, realizing the extrusion and fixation of the cable 3 in the vertical and lateral directions, and ensuring that the cable 3 is in a straight state through the four-way extrusion and fixation mechanism, greatly reducing the possibility of the cable 3 loosening.

[0055] On the basis of the above scheme, the present embodiment further improves the housing 7. Specifically, the housing 7 is further provided with a supporting airbag 9 located below the cable 3. The buffer airbag 73 has two connecting channels, which are respectively connected to the pushing airbag 82 and the supporting airbag 9, thereby giving the buffer airbag 73 an additional function, that is, being able to inflate the supporting airbag 9. By slowly inflating the supporting airbag 9 through the buffer airbag 73, the bottom of the cable 3 can be gradually lifted and the cable 3 can be tensioned, further causing the cable 3 to be in a straightened state, and effectively improving the fixing effect of the cable 3.

[0056] This embodiment also proposes an application method of an electronic fence auxiliary device for a substation, and the application method applies an electronic fence auxiliary device for a substation as described in any of the above technical solutions.

[0057] The working principle of the electronic fence auxiliary device for a substation provided in this embodiment is as follows:

[0058] 1. Initial state:

[0059] The pillar 1 stands vertically, with a hollow structure inside and a rectangular sliding space. The beam 2 is installed between two adjacent pillars 1. Part of the cable 3 is located in the sliding space, with both ends extending outward and deep into the beam 2. The rotating rod 41, connecting rod 42, sliding rod 49 and other components of the extrusion device 4 are in the initial positions. The sliding pressure piece 47 is located above the sliding space, and the first magnet 71 and the second magnet 472 between the shell 7 and the sliding pressure piece 47 are in a magnetic repulsion state.

[0060] 2. Rotation of the rotating rod 41:

[0061] The operator or the automatic control system starts to rotate the rotating rod 41, and the rotating rod 41 drives the connecting rod 42 to rotate together, and the sliding rod 49 on the connecting rod 42 also rotates accordingly.

[0062] 3. Sliding rod 49 slides:

[0063] The sliding rod 49 slides in the arc-shaped hole 46 on the pillar 1. Due to the design of the arc-shaped hole 46, the sliding of the sliding rod 49 drives the sliding pressure member 47 to move downward.

[0064] 4. The sliding member 47 moves downward:

[0065] The sliding and pressing member 47 moves downward in the sliding space, gradually approaches and presses the cable 3 . During this process, the magnetic repulsive force between the housing 7 and the sliding and pressing member 47 acts as a buffer, slowing down the downward movement speed of the sliding and pressing member 47 .

[0066] 5. Function of cushioning airbag 73:

[0067] When the sliding and pressing member 47 continues to move downward and contacts the buffer airbag 73 , the buffer airbag 73 begins to be squeezed, and the buffer airbag 73 slows down the downward movement speed of the sliding and pressing member 47 , and at the same time inflates the pushing airbag 82 .

[0068] 6. Push airbag 82 drive:

[0069] The airbag 82 is pushed to expand after being inflated, driving the connecting member 84 to move linearly. The gear 85 on the connecting member 84 moves linearly along the first rack 86, and the rotational movement of the gear 85 pushes the second rack 87 to move.

[0070] 7. Cable 3 multi-directional fixation:

[0071] The pressurizing portion 88 on the second rack 87 is in close contact with the side surface of the cable 3 to achieve squeezing and fixing of the cable 3 in the vertical and lateral directions. At this time, the cable 3 is firmly fixed inside the support 1 and maintained in a taut state.

[0072] 8. Function of support airbag 9:

[0073] If the fixing effect of the cable 3 needs to be further enhanced, the buffer airbag 73 can be used to inflate the support airbag 9. After the support airbag 9 is inflated, it expands and gradually lifts the cable 3 from below, thereby further tensioning the cable 3.

[0074] 9.Finish the fixation:

[0075] At this time, the locking piece 45 passes through the first locking hole 43 and the second locking hole 44 to lock the position of the rotating rod 41. After the above steps, the cable 3 is firmly fixed inside the electronic fence and kept in a taut state. The electronic fence can work normally to protect the safety of the substation area.

[0076] Optional steps: Unlock and adjust:

[0077] If the cable 3 needs to be adjusted or replaced, the connecting rod 42 and the sliding rod 49 can be released by unlocking the locking piece 45, and the rotating rod 41 can rotate in the opposite direction to drive the sliding pressure piece 47 to move upward, thereby releasing the cable 3. After making necessary adjustments, repeat the above steps to re-fix the cable 3.

[0078] This embodiment also proposes an application method of an electronic fence auxiliary device for a substation, and the application method applies an electronic fence auxiliary device for a substation as described in any of the above technical solutions.

[0079] In summary, the pillar 1 is cleverly designed as a vertical hollow structure, matched with the extrusion device 4 and the support block 5, and the rotation of the rotating rod 41 is used to realize the rotation of the connecting rod 42 and the sliding rod 49, thereby realizing the downward movement of the above-mentioned sliding pressure member 47, and then through the downward movement of the sliding pressure member 47, the online extrusion and fixation of the cable 3 inside the pillar 1 is realized. While being suitable for various harsh environments, it ensures that the cable 3 always remains taut, solving the problem of cable 3 loosening.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
