Description

Technical Field

[0001] This utility model relates to the field of cable outlet sleeve technology, specifically to an explosion-proof environmental protection cabinet cable outlet sleeve. Background Technology

[0002] Explosion-proof environmental protection cabinet outlet bushings are key components in high-voltage power distribution equipment used to connect internal conductors to external lines. Their core function is to ensure safe isolation of high-voltage electricity under extreme operating conditions, while adapting to environmentally friendly gas insulation or oil-free design requirements. The number of lines arranged inside the bushing needs to be comprehensively determined based on the voltage level, circuit function, equipment type, and design specifications.

[0003] In traditional technology, the wiring is arranged inside the bushing and an insulation layer is set on the outside of the wiring to prevent electric arcs or partial discharges. However, when there are multiple sets of wiring inside the bushing, it is inconvenient to maintain them when damage occurs and maintenance is required because the multiple sets of wiring are closely attached together. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an explosion-proof environmental protection cabinet outlet sleeve, which aims to solve the problem that it is inconvenient to maintain when multiple sets of lines are closely connected together during maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An explosion-proof environmental protection cabinet cable outlet sleeve includes a sleeve, with baffles symmetrically fixedly connected to one end of the inner side of the sleeve. A moving rod is slidably connected inside the baffle, and a cross plate is slidably connected outside the moving rod. A pressing plate is slidably connected inside the cross plate, and an arc-shaped groove is formed at one end of the pressing plate. A first spring is fixedly connected to the inner wall of the sleeve, and an arc-shaped plate is fixedly connected to one end of the first spring. The arc-shaped plate is adapted to fit the arc-shaped groove.

[0006] As a preferred embodiment of this utility model, a groove is provided on one side of the cross plate, and a through groove is provided at one end of the cross plate. The through groove and the interior of the groove are interconnected, and the extrusion plate extends to the outside of the cross plate through the through groove.

[0007] As a preferred embodiment of this utility model, a knob is fixedly connected to one end of the movable rod, and multiple sets of anti-slip textures are formed on the outside of the knob, with the multiple sets of anti-slip textures distributed at equal intervals.

[0008] As a preferred embodiment of this utility model, an installation sleeve is fixedly connected to the outside of the moving rod and located between the cross plate and the baffle. An installation ear is symmetrically fixedly connected to the outside of the installation sleeve. A guide rod is rotatably connected to the inside of the installation ear. The guide rod extends to the outside of the extrusion plate and is rotatably connected to the extrusion plate.

[0009] As a preferred embodiment of this utility model, a second spring is fixedly connected to the end of the moving rod away from the knob, and the second spring extends to the outside of one of the sets of baffles and is fixedly connected to the baffles.

[0010] As a preferred embodiment of this utility model, the cross plate is externally fixedly connected to a fixing rod, the fixing rod having an L-shaped structure design, the fixing rod extending to the inner side wall of the sleeve and being fixedly connected to the sleeve.

[0011] As a preferred embodiment of this utility model, the sleeve is made of epoxy resin material, and the sleeve has an internal interlayer, with a shielding mesh fixedly connected inside the interlayer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the mounting sleeve is moved by the moving rod, which then exerts a pulling force on the extrusion plate and retracts into the cross plate, thus stretching the second spring. After the circuit is placed inside the arc plate and arc groove, the moving rod is released, and the energy stored in the extension and retraction of the second spring drives the moving rod to reset, so that the circuit is stably attached to the arc plate and arc groove. At this time, the circuit is fixed inside different areas, with the exit portion being distinguished, which facilitates inspection and maintenance of different circuits during later maintenance.

[0013] In this invention, the breakdown field strength of epoxy resin can effectively isolate the high-voltage conductor from the external environment, prevent arcing or flashover accidents, significantly increase the creepage distance, adapt to harsh environments such as humidity and dirt, reduce the risk of surface discharge, and epoxy resin has good tensile strength, which can withstand the electrodynamic force generated by short-circuit current, avoiding bushing deformation or rupture.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1-3 This utility model provides a technical solution: An explosion-proof environmental protection cabinet outlet sleeve includes a sleeve 1. A baffle 2 is symmetrically fixedly connected to one end of the inner side of the sleeve 1. A moving rod 3 is slidably connected inside the baffle 2. A cross plate 4 is slidably connected to the outside of the moving rod 3. A pressing plate 5 is slidably connected inside the cross plate 4. An arc groove 6 is opened at one end of the pressing plate 5. A first spring 7 is fixedly connected to the inner wall of the sleeve 1. An arc plate 8 is fixedly connected to one end of the first spring 7. The arc plate 8 is adapted to the arc groove 6. By installing the sleeve 1 inside the environmental protection cabinet, and then passing the internal wiring of the environmental protection cabinet through the sleeve 1, for the convenience of maintenance and wiring layout in the future, the pressing plate 5 is first pressed to make it enter the interior of the cross plate 4. Then the wiring is placed inside the arc plate 8. Finally, the pressing plate 5 is reset, and the arc groove 6 and the arc plate 8 fit together. Under the energy storage of the extension and retraction of the first spring 7, the wiring is stably fitted inside both. At this time, the wiring is fixed inside different areas, and the outlet part is distinguished. This makes it convenient to check and maintain different wiring in the future.

[0017] Furthermore, in this embodiment, a groove is provided on one side of the cross plate 4, and a through groove is provided at one end of the cross plate 4. The through groove and the interior of the groove are interconnected. The extrusion plate 5 extends to the outside of the cross plate 4 through the through groove. The design of the through groove makes it convenient to slide the extrusion plate 5 to the outside of the cross plate 4.

[0018] Furthermore, in this embodiment, a knob 9 is fixedly connected to one end of the moving rod 3. Multiple anti-slip textures are provided on the outside of the knob 9. The multiple anti-slip textures are distributed at equal intervals. By pulling the knob 9, the anti-slip texture design will increase the friction between the fingers and prevent the moving rod 3 from slipping out of the hand when it is pulled. When the moving rod 3 slides, it will pass through the inside of the baffle 2 and the cross plate 4.

[0019] Furthermore, in this embodiment, an installation sleeve 10 is fixedly connected to the outside of the moving rod 3 and located between the cross plate 4 and the baffle 2. An installation ear is symmetrically fixedly connected to the outside of the installation sleeve 10. A guide rod 11 is rotatably connected inside the installation ear. The guide rod 11 extends to the outside of the extrusion plate 5 and is rotatably connected to the extrusion plate 5. When the moving rod 3 slides, it will drive the installation sleeve 10 to move. Then, a pulling force is applied to the guide rod 11. The guide rod 11 adjusts its direction inside the installation ear and then generates a pulling force on the extrusion plate 5, so that the extrusion plate 5 slides on the cross plate 4 and retracts into the interior of the cross plate 4.

[0020] Furthermore, in this embodiment, a second spring 12 is fixedly connected to the end of the moving rod 3 away from the knob 9. The second spring 12 extends to the outside of one of the baffles 2 and is fixedly connected to the baffle 2. When the moving rod 3 is subjected to tension, the second spring 12 will be subjected to the tension of the moving rod 3, and one end of the second spring 12 is fixed by the baffle 2, so that the second spring 12 is stretched. After the circuit is placed inside the arc plate 8 and the arc groove 6, by releasing the moving rod 3, the extension and retraction of the second spring 12 will drive the moving rod 3 to reset. At this time, the mounting sleeve 10 moves synchronously, and the guide rod 11 pushes the extrusion plate 5 to reset the extrusion plate 5.

[0021] Furthermore, in this embodiment, a fixing rod 13 is fixedly connected to the outside of the cross plate 4. The fixing rod 13 has an L-shaped structure design and extends to the inner side wall of the sleeve 1 and is fixedly connected to the sleeve 1. Through the design of the fixing rod 13, the cross plate 4 is suspended and fixed inside the sleeve 1. At this time, the smoothness is greatly improved when the moving rod 3 is pulled.

[0022] Furthermore, in this embodiment, the bushing 1 is made of epoxy resin material, and the bushing 1 has an internal interlayer with a shielding mesh fixedly connected inside the interlayer. The breakdown field strength of epoxy resin is much higher than that of air and some environmentally friendly gases, which can effectively isolate the high-voltage conductor from the external environment and prevent arcing or flashover accidents. At the same time, the dielectric loss factor of epoxy resin generates very little heat under high frequency or alternating electric fields, avoiding insulation aging caused by local overheating. The epoxy resin bushing 1 can significantly increase the creepage distance, adapt to harsh environments such as humidity and dirt, reduce the risk of surface discharge, and epoxy resin has good tensile strength, which can withstand the electrodynamic force generated by short-circuit current, preventing the bushing 1 from deforming or breaking.

[0023] In this embodiment, the specific implementation scenario is as follows: The sleeve 1 is installed inside the environmental protection cabinet, and then the internal wiring of the cabinet passes through the sleeve 1. For ease of maintenance and wiring arrangement later, the knob 9 is pulled. The anti-slip texture design increases friction between the fingers, preventing slippage when the moving rod 3 is pulled. The moving rod 3 slides through the baffle 2 and the cross plate 4, causing the mounting sleeve 10 to move. A pulling force is then applied to the guide rod 11, which adjusts its direction inside the mounting ear. This then pulls on the extrusion plate 5, causing it to slide within the cross plate 4 and retract into it. The second spring 12 is pulled by the moving rod 3, and one end of the second spring 12 is fixed by the baffle 2, thus stretching the second spring 12. After the wiring is placed inside the arc plate 8 and the arc groove 6, the moving rod 3 is released, and then the second... The extension and retraction of spring 12 drives the moving rod 3 to reset. At this time, the mounting sleeve 10 moves synchronously, and the guide rod 11 pushes the extrusion plate 5 to reset it. Under the extension and retraction of the first spring 7, the line is stably attached to the inside of the two. At this time, the line will be fixed inside different areas, and the outlet part is distinguished. In the later maintenance, it is convenient to check and maintain different lines. The breakdown field strength of epoxy resin is much higher than that of air and some environmentally friendly gases, which can effectively isolate the high voltage conductor from the external environment and prevent arc or flashover accidents. At the same time, the dielectric loss factor of epoxy resin generates very little heat under high frequency or alternating electric field, avoiding insulation aging caused by local overheating. Epoxy resin sleeve 1 can significantly increase the creepage distance, adapt to harsh environments such as humidity and dirt, reduce the risk of surface discharge, and epoxy resin has good tensile strength, which can withstand the electrodynamic force generated by short circuit current and prevent the sleeve 1 from deforming or breaking.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
