Description

Technical Field

[0001] This utility model relates to the field of fixed boxes, and in particular to a mesh sleeve fastening device for fixing cables in box-type substations. Background Technology

[0002] The existing method of fixing cables at the lower end of transformer substations mainly relies on clamps at the substation openings. This method has the following drawbacks: 1. The clamp fixation is unreliable. The clamp only relies on one or two points of connection for force, and over time, the fixing patch is prone to deformation, causing the cable to sink and pull off the cable head, resulting in an accident. 2. The cable clamps used are made of rigid metal, while the cable sheath is a flexible insulating layer. The rigid metal clamp acts directly on the insulation layer. During installation and use, if improperly operated or subjected to external forces, the rigid metal clamp can easily come into direct contact with the cable surface and generate friction, which may scratch the cable's outer insulation layer, reduce the cable's insulation performance, and in severe cases, even expose the internal conductors, causing short circuits and other safety accidents. Therefore, we propose a braided cable fastening device for fixing transformer substation cables to solve the above problems. Utility Model Content

[0003] This utility model provides a mesh sleeve fastening device for fixing transformer substation cables, which solves the problems of unreliable clamp fixing, easy deformation of the fixing patch over time, which causes the cable head to be pulled off after the cable sinks; rigid metal clamps are prone to direct contact with the cable surface and friction during installation and use, which may scratch the outer insulation layer of the cable and cause safety accidents such as short circuits.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mesh sleeve fastening device for fixing transformer cables, including a mesh sleeve and a box base. The top of the mesh sleeve is provided with multiple hanging ropes, and the box base is provided with multiple mounting seats. The hanging ropes are connected to the mounting seats. One end of the mesh sleeve is provided with a soft sleeve, and the soft sleeve is provided with a locking device. The locking device includes a base and a turntable.

[0005] In the preferred embodiment, the cable passes through the mesh sleeve, one end of the suspension rope is equipped with a bolt, the bolt is threadedly connected to the mounting base, and a nut is provided on the bolt.

[0006] In the preferred embodiment, the bottom of the netting is provided with multiple arc-shaped mesh belts, the soft sleeve passes through the arc-shaped mesh belts, the arc-shaped mesh belts have a hollow structure, and multiple ropes are provided on the arc-shaped mesh belts, with the ropes passing through the arc-shaped mesh belts.

[0007] In the preferred embodiment, the turntable includes a disc body, a sleeve on the disc body, support plates at both ends of the sleeve, wire holes on the support plates, and multiple through holes on the disc body.

[0008] In the preferred embodiment, one end of the cord is connected to the threading hole, and a top cover is provided on the top of the turntable.

[0009] In the preferred embodiment, the base has threading holes on both sides, through which the cord passes. The base also has two retaining strips, one side of which has an arc-shaped structure.

[0010] In the preferred embodiment, the locking strip rests against the sleeve, one end of the locking strip has a locking platform, one side of the locking platform has a rounded corner, and a second spring is provided between the two locking strips.

[0011] In the preferred embodiment, the base is provided with multiple flat-bottomed holes, a first spring is provided in the flat-bottomed holes, a locking pin is provided on the first spring, the locking pin abuts against the through hole, and a frustum is provided at one end of the locking pin.

[0012] The beneficial effects of this utility model are as follows: The cable enters the transformer substation chamber through the cable hole. A mesh sleeve is wrapped around the cable, and one end of the mesh sleeve is connected to the base of the transformer substation via a suspension rope. The mesh sleeve is subjected to tension at one end, causing it to contract and tighten the cable. The cable's own weight provides tension to the mesh sleeve, thus supporting its own weight. Simultaneously, if the cable settles, the mesh sleeve tightens even more, again providing tension to the mesh sleeve and further tightening the support, preventing the cable end from being pulled off. This avoids the situation where, with the use of cable clamps, the fixing patches can easily deform over time, leading to the cable head being pulled off after the cable settles, causing an accident.

[0013] When installing cables in the braided sleeve, the cable passes through the braided sleeve, and the flexible sleeve rests against multiple curved braided belts. Raising the top cover lifts the turntable, causing two locking strips to press against the second spring, resulting in relative movement of the two locking strips and the locking platform pressing against the sleeve. Rotating the top cover causes multiple ropes to slowly wind around the support plate, tightening the flexible sleeve at the bottom and clamping the cable. The flexible sleeve is not made of metal, avoiding direct contact and friction between the cable surface and rigid metal clamps during installation and use, which could scratch the cable's outer insulation layer and cause short circuits or other safety accidents. Furthermore, by adjusting the locking device, the overall structure can accommodate cables of different thicknesses, making it more adaptable and possessing significant potential for widespread adoption.

[0024] Example 1:

[0025] like Figure 1-8 The mesh sleeve fastening device for fixing the cables of the transformer substation includes a mesh sleeve 1 and a box base 14. Multiple suspension ropes 101 are provided on the top of the mesh sleeve 1, and multiple mounting seats 11 are provided on the box base 14. The suspension ropes 101 are connected to the mounting seats 11. A flexible sleeve 9 is provided at one end of the mesh sleeve 1, and a locking device 2 is provided on the flexible sleeve 9. The locking device 2 includes a base 4 and a turntable 3. With this structure, the cable 13 enters the transformer substation chamber through the cable hole. A mesh sleeve 1 is wrapped around the cable 13. One end of the mesh sleeve 1 is connected to the box base 14 via the suspension ropes 101. The mesh sleeve 1 is subjected to tension at one end, causing it to contract and tighten the cable 13. The weight of the cable 13 provides tension to the mesh sleeve 1, thus supporting its own weight. Simultaneously, if the cable 13 settles, the mesh sleeve 1 will further tighten the cable 13, providing additional tension and preventing the cable 13 end from pulling off. Avoid using clamps to fix cable 13. Over time, the fixing patch may deform, causing cable 13 to sink and pull the cable head off, resulting in an accident.

[0026] When cable 13 is installed in the mesh sleeve 1, cable 13 passes through the mesh sleeve 1, and the flexible sleeve 9 abuts against multiple arc-shaped mesh belts 102. The top cover 5 is raised, causing the turntable 3 to rise, which in turn causes two clamping strips 401 to press against the second spring 8, allowing the two clamping strips 401 to move relative to each other, causing the clamping platform 402 to abut against the sleeve 302. The top cover 5 is rotated, causing multiple ropes 10 to slowly wind around the support plate 303, tightening the flexible sleeve 9 at the bottom and clamping the cable 13. The flexible sleeve 9 is not made of metal, avoiding direct contact and friction between the cable surface and rigid metal clamps during installation and use, which could scratch the outer insulation layer of the cable and cause short circuits or other safety accidents. Simultaneously, by adjusting the locking device 2, the overall structure can accommodate cables 13 of different thicknesses, making it more adaptable.

[0027] In the preferred embodiment, cable 13 passes through the mesh sleeve 1, and one end of the suspension rope 101 is bolted, which is threaded to the mounting base 11. A nut 12 is attached to the bolt. With this structure, one end of the mesh sleeve 1 is connected to the base 14 of the enclosure via the suspension rope 101. The mesh sleeve 1 is subjected to tension, causing it to contract and tighten the cable 13. The weight of the cable 13 provides tension to the mesh sleeve 1, thus supporting its own weight. Simultaneously, if the cable 13 settles, the mesh sleeve 1 will further tighten the cable 13, providing additional tension and support to prevent the cable 13 end from pulling off. This avoids the situation where, with the use of clamps to fix the cable 13, the fixing patch can easily deform over time, leading to the cable 13 settling and pulling off the cable head, causing an accident.

[0028] In the preferred embodiment, the bottom of the net sleeve 1 is provided with multiple arc-shaped mesh belts 102, and the flexible sleeve 9 passes through the arc-shaped mesh belts 102. The arc-shaped mesh belts 102 have a hollow structure, and multiple ropes 10 are provided on the arc-shaped mesh belts 102, with the ropes 10 passing through the arc-shaped mesh belts 102. With this structure,

[0029] In the preferred embodiment, the turntable 3 includes a disc body 301, a sleeve 302 on the disc body 301, support plates 303 at both ends of the sleeve 302, wire holes 3031 on the support plates 303, and multiple through holes 304 on the disc body 301. With this structure, multiple ropes 10 are installed on the wire holes 3031. When the top cover 5 is rotated, the multiple ropes 10 are wound around the support plates 303, causing the flexible sleeve 9 to clamp the cable 13. After the cable 13 is installed in place, the top cover 5 is pressed down, causing the locking pin 6 to abut against the through hole 304, causing the locking platform 402 at one end of the locking strip 401 to protrude from the sleeve 302. The two locking strips 401 separate under the action of the second spring 8, thus fixing the ropes 10.

[0030] In the preferred embodiment, one end of the cord 10 is connected to the thread hole 3031, and the top of the turntable 3 is provided with a top cover 5.

[0031] In the preferred embodiment, the base 4 has threading holes 404 on both sides, through which the cord 10 passes. The base 4 also has two retaining strips 401, one side of which is curved. With this structure...

[0032] In the preferred embodiment, the locking strip 401 abuts against the sleeve 302. One end of the locking strip 401 is provided with a locking platform 402, and one side of the locking platform 402 is rounded. A second spring 8 is provided between the two locking strips 401. With this structure, the locking platform 402 is rounded on one side so that when the operator pulls the top cover 5, the locking platform 402 can slide into the sleeve 302, so that the two locking strips 401 retract.

[0033] In the preferred embodiment, the base 4 has multiple flat-bottomed holes 403, each with a first spring 7. The first spring 7 has a locking pin 6, which abuts against the through hole 304. One end of the locking pin 6 has a frustum. With this structure, after the cord 10 has retracted, pressing the top cover 5 causes the turntable 3 to move downwards, opening the two locking strips 401 and engaging the multiple locking pins 6 in the through hole 304.

[0034] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
