Technical Field

[0001] This invention relates to the field of withdrawable switchgear technology, specifically a GCS type low-voltage withdrawable switchgear. Background Technology

[0002] GCS is a complete set of switchgear designed for use in power systems such as power plants, substations, and industrial and mining enterprises with a rated voltage of 400V and below. It is used for power distribution, motor control, reactive power compensation, and protection. Its most distinctive feature is that the main functional units are installed in drawers that can be pulled out independently. Its drawer-type design is the soul of its system, which greatly improves power supply reliability and maintenance efficiency. It is a key component of modern automated power distribution systems.

[0003] In order to reduce operating force, existing low-voltage withdrawable switchgear uses inappropriate lubricants on the guide rails and interlocking mechanisms. For example, grease that easily attracts dust or machine oil that corrodes plastics can form sludge over time, which can aggravate wear or cause the mechanism to jam. Summary of the Invention

A through-hole is opened in the inner cavity of the meshing block, and a pull-out plate is attached to the through-hole.

[0008] Preferably, the top of the rectangular frame is fixedly connected to two connecting rods, which are symmetrically arranged front and back. Both connecting rods are fixedly connected to a baffle, and sliders are fixedly connected to both the front and back sides of the baffle.

[0015] Please see Figure 1-12 The present invention provides a technical solution: A GCS-type low-voltage withdrawable switchgear includes a switchgear 1. Heat dissipation vents are provided on both the left and right sides of the switchgear 1. A mounting plate 29 is fixedly connected to the inside of the switchgear 1. A main switch appliance 30 is bolted to the front of the switchgear 1. A primary moving plug 28 is located near the top of the rear of the switchgear 1. Two primary static sockets 32 are located near the bottom of the rear of the switchgear 1. Several cables 27 are plugged into both sides of the main switch appliance 30, with the other ends of each cable passing through the inner cavity of the mounting plate 29 and plugged into the primary static sockets 32. A pull plate 31 is fixedly connected to the front of the switchgear 1. Two rollers 6 are installed on both the left and right sides of the switchgear 1. Anti-detachment plates 7 are fixedly connected to the top of both the left and right sides of the switchgear 1. Cleaning mechanisms are provided on both the left and right sides of the switchgear 1. Cabinet doors 2 are provided on both the left and right sides of the switchgear 1. Ventilation vents are provided on the outer sides of the cabinet doors 2 near the center. Each cabinet has two slots, symmetrically arranged front and back. A base plate 11 is fixedly connected to the corresponding side of each cabinet door 2 near the center. The top of the base plate 11 is attached to the anti-detachment plate 7. A flip plate 9 is hinged to the slot. A guide plate 8 is hinged to the front and rear sides of the switch cabinet 1 near the center. Several return springs 10 are fixedly connected to the top of the guide plate 8, arranged linearly from front to back. The bottom of each return spring 10 is fixedly connected to the guide plate 8. Through these components, when the baffle 16 moves upward, it can cause the two flip plates 9 to flip. When the two flip plates 9 flip, they can cause the guide plate 8 to flip downward. Furthermore, when the baffle 16 moves upward, it can block the exhaust vent. The temperature generated by the electrical components inside the switch cabinet 1 during operation, in conjunction with the guide plate 8, heats and softens the grease on the top of the guide rail 22, facilitating cleaning by the cleaning mechanism.

[0016] The cleaning mechanism includes two rectangular frames 4. A lead screw 5 runs through the inner cavity of each rectangular frame 4. A meshing block 14 engages with the outer side of the lead screw 5 near its rear end. A crank handle 13 is fixedly connected to the front end of the lead screw 5. A through-hole is opened in the inner cavity of the meshing block 14, and a pull-out plate 15 is attached to the through-hole. Two connecting rods 18 are fixedly connected to the top of the rectangular frame 4. The two connecting rods 18 are symmetrically arranged front and back. A baffle 16 is fixedly connected to both the two connecting rods 18. Slider blocks 17 are fixedly connected to both the front and rear sides of the baffle 16. Limiting plates 3 are fixedly connected to both the front and rear sides of the cabinet door 2. Several slots are opened on the outer side of the limiting plate 3 on the front side. The slots are arranged linearly from top to bottom. A groove is opened on the top of the slider 17 on the front side. The groove is fixedly connected to... There is a movable spring 21, and a locking block 20 is attached to the slot. The locking block 20 is fixedly connected to the movable spring 21. An opening is opened on the outside of the cabinet door 2 near the bottom. A fixed plate 19 is fixedly connected to the bottom of the corresponding side of the two cabinet doors 2. A hinge block 25 is attached to the bottom of the inner cavity of the fixed plate 19. Two cranks 33 are hinged to the inner cavity of the hinge block 25. The two cranks 33 are symmetrically arranged front and back. A movable plate 26 is hinged to the top of the two cranks 33. A slide plate 23 is fixedly connected to the top of the movable plate 26. A guide rail 22 is slidably connected to the top of the slide plate 23. The top of the guide rail 22 is attached to the roller 6. A moving rod 24 is hinged to the front side of the hinge block 25. The front end of the moving rod 24 passes through the inner cavity of the fixed plate 19 and is fixedly connected to the pull rod 12.

[0017] Working principle: When it is necessary to clean the lubricating oil on the surface of the guide rail 22, the pull rod 12 can be pulled forward first. When the pull rod 12 moves, it can drive the moving rod 24 to move. When the moving rod 24 moves, it can pull the hinge block 25 to move. When the hinge block 25 moves, the two cranks 33 flip. When the cranks 33 flip, they can drive the movable plate 26 to move downward. When the movable plate 26 moves, it can drive the slide plate 23 to move downward. When the slide plate 23 moves, it can drive the guide rail 22 to move downward synchronously, so that the guide rail 22 moves to the horizontal position of the opening. Then, it drives the rectangular frame 4 to move upward. When the rectangular frame 4 moves, it can drive the baffle 16 to move upward through the connecting rod 18. When the baffle 16 moves, it can block the exhaust hole to prevent the hot air from the electrical components inside the switch cabinet 1 from being discharged through the exhaust hole. When the baffle 16 moves, it can cause the two flip plates 9 to flip. When the flip plates 9 flip, they can cause the guide plate 8 to flip. When the guide plate 8 flips, it can help the hot air blow the lubricant on the top of the guide rail 22. If it is necessary to limit the height of the baffle 16, the locking block 20 can be pressed to disengage from the slot. When the baffle 16 moves to the preset position, it can cause the locking block 20 to insert into the adjacent slot to fix the baffle 16. When the rectangular frame 4 moves to the horizontal position of the opening, the crank handle 13 can be rotated to drive the lead screw 5 to rotate. When the lead screw 5 rotates, it can drive the engagement block 14 to move and move the pull plate 15 towards the switch cabinet 1, so that the bottom of the pull plate 15 fits with the top of the guide rail 22. When the engagement block 14 moves, it can drive the pull plate 15 to move and clean the lubricant.
