Description

Technical Field

[0001] This invention relates to the field of switch cabinets, specifically a lightning-proof outdoor switch cabinet. Background Technology

[0002] Outdoor switchgear is an electrical device installed in an outdoor environment for power distribution, control, and protection. It typically includes components such as circuit breakers, disconnect switches, instrument transformers, and protection devices. It is widely used in power grids, industrial and mining enterprises, rail transportation, and other applications, undertaking functions such as power distribution, circuit switching, and fault protection.

[0003] Outdoor switchgear is exposed to open environments. If there are no taller buildings or lightning rods nearby for protection, it may be directly struck by lightning, causing equipment damage, insulation breakdown, or even fire. Even if lightning does not directly strike the switchgear, the electromagnetic or electrostatic induction generated by nearby lightning strikes can generate instantaneous high voltages on cables and busbars, damaging internal electronic components. Therefore, outdoor switchgear needs to have lightning protection. The lightning rods on existing switchgear are usually bolted to the top of the switchgear. Maintenance requires climbing or the use of auxiliary equipment. Due to the complex outdoor terrain, the difficulty of placing climbing equipment is increased, making it difficult to inspect the lightning rods and resulting in low safety. Summary of the Invention

[0004] The purpose of this invention is to provide a lightning-proof outdoor switchgear to solve the problems mentioned in the background art.

Two screws are rotatably installed between the inner side of the base box and the inner top wall of the mounting box. Moving blocks are threaded onto the outer sides of the screws. A mounting bracket is fixedly installed between the two moving blocks. An optical shaft for limiting the sliding of the moving blocks is fixedly installed on the inner side of the mounting box. The end of the lightning rod near the lead wire is fixedly installed on the inner side of the mounting bracket. A synchronous belt is rotatably installed between the two screws. The synchronous belt is located on the inner side of the base box. A drive motor is fixedly installed at the bottom of the base box. The output end of the drive motor is fixedly connected to the adjacent screw.

[0008] Preferably, the leak-proof mechanism includes a mounting cavity formed at the top of the switch cabinet body. A sealing plate is provided on the inner side of the mounting cavity. The size of the sealing plate is larger than the size of the movable through hole on the switch cabinet body. A mounting rod is rotatably mounted on one side of the sealing plate. The mounting rod extends to the outside of the mounting box, and a protrusion is provided on the outside of the mounting box for the bottom end of the mounting rod to be rotatably mounted. A sleeve is slidably mounted on the outside of the mounting rod. The sleeve is fixedly connected to the mounting bracket via a sliding plate. An elongated groove is provided on the outside of the mounting box for the sliding plate to be limited. Two symmetrically distributed sliders are fixedly mounted on the inner side of the sleeve. A spiral groove is provided on the outside of the mounting rod for the sliders to be limited. Vertical grooves are provided at both ends of the spiral groove.

[0009] Preferably, the quick-release mechanism includes a first suspension plate fixedly installed on the outside of the mounting plate, a positioning plate fixedly installed on the outside of the mounting plate and located outside the first suspension plate, a second suspension plate hinged to the outside of the positioning plate, mounting holes on the outside of both the first and second suspension plates, maintenance openings on the outside of both the mounting plate and the mounting box, a baffle slidably installed in the maintenance opening on the mounting plate, a sliding cavity for limiting the sliding of the baffle inside the mounting plate, a plurality of equally spaced pull straps fixedly installed between the baffle and the second suspension plate, a roller bracket cooperating with the pull straps fixedly installed inside the sliding cavity, a plurality of equally spaced positioning springs fixedly installed between the baffle and the inside of the sliding cavity, and two symmetrically distributed sliding rods fixedly installed between the detection opening of the mounting plate and the inside of the sliding cavity, the sliding rods slidingly penetrating the baffle.

[0010] Preferably, a take-up reel that cooperates with the lead wire is fixedly installed on the inner side of the mounting plate.

[0011] Preferably, a sealing ring is fixedly installed inside the movable perforation of the switch cabinet body.

[0012] Preferably, two sliding balls are rotatably mounted on the bottom of the sealing plate, and an arc-shaped groove is provided on the inner side of the mounting cavity for the sliding balls to be limited and slid.

[0013] Preferably, an arc-shaped rod is fixedly installed on the inner side of the mounting cavity, the arc-shaped rod slides through the sealing plate, and an arc-shaped spring is provided on the outer side of the arc-shaped rod, and the arc-shaped spring is fixedly installed between the inner side of the mounting cavity and the outer side of the sealing plate.

[0015] Preferably, a U-shaped handle is fixedly installed on the outer side of the first suspension plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention utilizes an adjustment mechanism to retract the lightning rod into the switchgear body, facilitating maintenance by personnel without requiring climbing. The lightning rod can also be moved to the top of the switchgear body via a movable perforation in the mounting box and switchgear body, ensuring protection for the switchgear body. Furthermore, the lightning rod's position is far from the equipment installation location within the switchgear body, thus not affecting the normal installation and use of the equipment, thereby improving the safety of lightning rod maintenance.

[0018] This invention utilizes a leak-proof mechanism that allows a slider inside the sleeve to move along the spiral groove on the mounting rod as the lightning rod moves downwards. The slider then rotates the mounting rod 90 degrees, causing the sealing plate to block the moving perforation on the switchgear body, preventing rainwater from entering and providing protection for the switchgear body. When the lightning rod moves upwards, the sealing plate automatically opens, thus achieving a sealing and leak-proof effect.

[0019] This invention utilizes a quick-release mechanism to remove the first suspension plate from the wall. This mechanism allows the first suspension plate to be pulled, causing the positioning plate to swing outward with the second suspension plate as a fulcrum. The mounting plate can then be moved away from the wall. Furthermore, by pulling the baffle with a strap, the inspection opening on the mounting plate can be opened, facilitating the maintenance of the lightning rod inside the mounting box by the staff, thereby improving maintenance efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8The diagram shows a lightning-protected outdoor switchgear, comprising a switchgear body 1 and a mounting plate 2 fixedly installed on the outside of the switchgear body 1. A mounting box 3 is fixedly installed on the inner side of the mounting plate 2, and a lightning rod 4 is installed inside the mounting box 3. Both the top of the switchgear body 1 and the top of the mounting box 3 have movable through holes for the lightning rod 4 to slide and limit its movement. The lightning rod 4 can move through these through holes to the top of the switchgear body 1 to guide lightning. A sealing ring 31 is fixedly installed inside the movable through hole of the switchgear body 1, so that when the lightning rod 4 moves to the top of the switchgear body 1, the sealing ring 31 can fit over the outside of the lightning rod 4 to prevent rainwater from entering the switchgear body 1. A [missing information - likely a device or component] is installed at the bottom of the lightning rod 4. The lead wire 5 is fixedly installed on the inner side of the mounting plate 2, and a take-up reel 30 is fixedly installed to cooperate with the lead wire 5 for easy take-up and take-up of the lead wire 5. One end of the lead wire 5 is fixedly installed with a grounding grid 6 located below the switch cabinet body 1, so that the lightning rod 4 can guide the lightning to the grounding grid 6 through the lead wire 5. The grounding grid 6 can release the energy of the lightning to the ground and provide protection for the switch cabinet body 1. It also includes: an adjustment mechanism for moving and storing the lightning rod 4, which is installed on the inner side of the mounting box 3; a leak-proof mechanism for sealing and waterproofing the moving perforations on the switch cabinet body 1, which is installed on the inner side of the switch cabinet body 1; and a quick-release mechanism for opening and inspecting the switch cabinet body 1, which is installed on the outer side of the mounting plate 2.

[0031] The adjustment mechanism includes a base box 7 fixedly installed at the bottom of the mounting box 3. The bottom of the base box 7 has an opening for the lead wire 5 to pass through. Two screws 8 are rotatably installed between the inner side of the base box 7 and the inner top wall of the mounting box 3. Moving blocks 9 are threaded onto the outer sides of the screws 8. A mounting sleeve 10 is fixedly installed between the two moving blocks 9. An optical axis 11 is fixedly installed inside the mounting box 3 to limit the sliding movement of the moving blocks 9. When the two screws 8 rotate, they can drive the corresponding moving blocks 9 to move along the outer side of the optical axis 11, causing the two moving blocks 9 to drive the mounting sleeve 10 to move synchronously. The lightning rod 4 is positioned near the end of the lead wire 5. The lightning rod 4 is fixedly installed inside the mounting bracket 10, allowing the mounting bracket 10 to move the lightning rod 4 up and down, thus enabling the lightning rod 4 to be retracted downwards and extended upwards. A synchronous belt 12 is rotatably installed between the two screws 8, located inside the base box 7, so that the two screws 8 can rotate synchronously. A drive motor 13 is fixedly installed at the bottom of the base box 7, and the output end of the drive motor 13 is fixedly connected to the adjacent screw 8, so that the drive motor 13 can drive the corresponding screw 8 to rotate. This screw 8 drives the other screw 8 to rotate synchronously through the synchronous belt 12, thus enabling the lightning rod 4 to rise and fall rapidly.

[0032] Example 2: Please refer to Figures 1-6This embodiment further illustrates Example 1. The leakage prevention mechanism shown in the figure includes a mounting cavity 14 formed on the top of the switch cabinet body 1. A sealing plate 15 is provided on the inner side of the mounting cavity 14. The size of the sealing plate 15 is larger than the size of the movable through hole on the switch cabinet body 1, so that the sealing plate 15 can seal the movable through hole on the switch cabinet body 1. A mounting rod 16 is rotatably mounted on one side of the sealing plate 15. The mounting rod 16 extends to the outside of the mounting box 3, and a protrusion is provided on the outside of the mounting box 3 for the bottom end of the mounting rod 16 to be rotatably mounted. A sleeve 17 is slidably mounted on the outside of the mounting rod 16. The sleeve 17 is fixedly connected to the mounting bracket 10 through a sliding plate 18. A long sliding limit is provided on the outside of the mounting box 3 for the sliding plate 18 to be limited. The groove allows the mounting bracket 10 to move synchronously along the inner side of the sliding plate 18. The sliding plate 18, in turn, allows the sleeve 17 to move along the outer side of the mounting rod 16. Two symmetrically distributed sliders 19 are fixedly installed on the inner side of the sleeve 17. A spiral groove 20 is provided on the outer side of the mounting rod 16 to limit the sliding of the sliders 19. When the sleeve 17 moves, it allows the sliders 19 to move along the inner side of the spiral groove 20. The sliders 19 then rotate the mounting rod 16 90 degrees through the spiral groove 20. This causes the mounting rod 16 to swing the sealing plate 15 away from the moving perforation on the switchgear body 1, facilitating the upward movement of the lightning rod 4. When the lightning rod 4 is retracted downwards, the sliders 19 can... The spiral groove 20 drives the mounting rod 16 to rotate and reset, causing the sealing plate 15 to seal the moving opening and prevent rainwater from entering the switch cabinet body 1. Vertical grooves 21 are provided at both ends of the spiral groove 20, allowing the slider 19 to move from the spiral groove 20 to the vertical groove 21 during movement, thus positioning the mounting rod 16 and preventing the sealing plate 15 from rotating. Two ball bearings 32 are rotatably mounted on the bottom of the sealing plate 15. An arc-shaped groove is provided on the inner side of the mounting cavity 14 for the ball bearings 32 to slide and be limited, allowing the sealing plate 15 to move along the inner side of the arc-shaped groove during swinging, reducing the friction between the sealing plate 15 and the inner side of the mounting cavity 14, facilitating rapid swinging of the sealing plate 15. An arc-shaped rod 33 is fixedly installed on the inner side of the mounting cavity 14. The arc-shaped rod 33 slides through the sealing plate 15 to guide the swing of the sealing plate 15. An arc-shaped spring 34 is provided on the outer side of the arc-shaped rod 33. The arc-shaped spring 34 is fixedly installed between the inner side of the mounting cavity 14 and the outer side of the sealing plate 15. The elasticity of the arc-shaped spring 34 can be used to facilitate the spiral groove 20 and the vertical groove 21 to abut against the slider 19, so that the slider 19 can move smoothly along the inner side of the spiral groove 20 and the vertical groove 21. A guide sleeve 35 is fixedly installed on the top of the protrusion on the mounting box 3. The sleeve 17 is slidably installed on the inner side of the guide sleeve 35 to guide the movement of the sleeve 17 and prevent dust in the switch cabinet body 1 from entering the spiral groove 20 and the vertical groove 21.

[0033] Example 3: Please refer to Figures 1-8This embodiment further illustrates other embodiments. The quick-release mechanism shown in the figure includes a first suspension plate 22 fixedly installed on the outside of the mounting plate 2. A positioning plate 23 located outside the first suspension plate 22 is fixedly installed on the outside of the mounting plate 2. A second suspension plate 24 is hinged to the outside of the positioning plate 23. Mounting holes are provided on the outer sides of both the first suspension plate 22 and the second suspension plate 24, so that both the first suspension plate 22 and the second suspension plate 24 can be installed on the wall through the mounting holes and bolts. This facilitates the suspension of the switch cabinet body 1 on the outdoor wall. When the first suspension plate 22 is removed from the wall, the operator can pull the first suspension plate 22 to make the switch cabinet body 1 swing around the hinge point of the second suspension plate 24 and the positioning plate 23. Inspection openings are provided on the outer sides of both the mounting plate 2 and the mounting box 3, so that the operator can inspect the lightning rod 4 stored therein through the two inspection openings. A baffle 25 is slidably installed in the inspection opening on the mounting plate 2. The interior of the mounting plate 2 has a limit for the sliding of the baffle 25. The slide cavity has multiple equally spaced pull straps 26 fixedly installed between the baffle 25 and the second suspension plate 24. A roller bracket 27, which cooperates with the pull straps 26, is fixedly installed on the inner side of the slide cavity. When the switch cabinet body 1 swings, the pull straps 26 can pull the baffle 25 along the outer side of the roller bracket 27 to move it along the inner side of the slide cavity, opening the maintenance opening on the mounting plate 2. Multiple equally spaced positioning springs 28 are fixedly installed between the baffle 25 and the inner side of the slide cavity, so that when the baffle 25 moves, it can engage the positioning springs. When the first suspension plate 22 is stretched, the rebound force of the positioning spring 28 can be used to quickly reset the baffle 25 when the first suspension plate 22 comes into contact with the wall again. Two symmetrically distributed slide rods 29 are fixedly installed between the detection opening of the mounting plate 2 and the inner side of the sliding cavity. The slide rods 29 slide through the baffle 25, so that the baffle 25 can move along the outer side of the slide rods 29, improving the stability of the movement of the baffle 25. A U-shaped handle 36 is fixedly installed on the outer side of the first suspension plate 22 to facilitate pulling the first suspension plate 22 to move.

[0034] Working principle: First, the operator removes the bolts between the first suspension plate 22 and the wall, and pulls the U-shaped handle 36. This causes the first suspension plate 22 to swing outwards via the mounting plate 2 and the positioning plate 23, with the second suspension plate 24 as the fulcrum. The mounting plate 2 then moves the switch cabinet body 1 synchronously away from the wall. Meanwhile, the second suspension plate 24 remains stationary, causing the pull belt 26 to pull the baffle 25 along the inner side of the roller bracket 27, moving it along the sliding cavity of the mounting plate 2 and opening the inspection opening on the mounting plate 2. Then, the operator starts the drive motor 13, which drives the corresponding screw 8 to rotate. This screw 8, via the synchronous belt 12, drives another screw 8 to rotate synchronously. Both screws 8 drive the corresponding moving blocks 9 to move downwards along the outer side of the optical axis 11, causing the two moving blocks 9 to move the mounting bracket 10 synchronously. The mounting bracket 10 then moves the lightning rod 4 downwards along the moving through hole on the switch cabinet body 1, retracting the lightning rod 4 into the mounting box 3. The sleeve 10 drives the sliding plate 18 to move along the long groove on the mounting box 3. The sliding plate 18 drives the sleeve 17 to move along the outside of the mounting rod 16. The slider 19 on the inside of the mounting rod 16 moves along the vertical groove 21 on the mounting rod 16. When the slider 19 enters the spiral groove 20 from the vertical groove 21, the lightning rod 4 has completely entered the mounting box 3. As the slider 19 moves, it works with the spiral groove 20 to drive the mounting rod 16 to rotate. The mounting rod 16 drives the sealing plate 15 to rotate 90 degrees along the inside of the mounting cavity 14, blocking the moving perforation on the switch cabinet body 1 and preventing water, dust and impurities on the switch cabinet body 1 from entering the switch cabinet body 1. Thus, the staff can inspect the lightning rod 4 in the mounting box 3. Finally, the staff restarts the drive motor 13 to extend the lightning rod 4 upward and installs the first suspension plate 22 onto the wall, thus completing the inspection of the lightning rod 4 without climbing, achieving the effect of safe inspection and improving the inspection efficiency of the lightning rod 4.
