[0002] A power distribution cabinet for strong magnetic fields is a device used to improve the voltage quality of the power system, enhance the system efficiency and ensure the stable operation of power equipment. Such a switch cabinet is usually used in a 35 kV power system, and its main function is to filter harmonics in the power system and compensate for reactive power, so as to improve the power factor of the power system and the power supply quality of the power grid.

[0003] However, in the prior art, an existing power distribution cabinet for strong magnetic fields flips the upper and lower baffles through the cooperation of a lifting rod, so that the upper and lower baffles are closed for shielding. However, the lifting rod is not as powerful as the chain and sprocket system, and the force transmission of the lifting rod is not stable enough. The baffle is prone to tilt or flip when the force is unbalanced. At the same time, the lifting mechanism and the guide rail inside the existing power distribution cabinet for strong magnetic fields are both made of magnetic materials, which will cause the trolley to get stuck when entering and exiting under the interference of strong magnetic fields, and even cause faults or misoperations. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a power distribution cabinet for strong magnetic fields.

The sprockets are meshed and connected with the corresponding chains. Connecting pieces are fixedly connected to the bottoms of the chains. Connecting rods are fixedly connected to the bottoms of the connecting pieces. The connecting rods are arranged in a cross manner.

[0006] As a preferred embodiment, side plates are fixedly connected to both sides of the inner wall of the switch cabinet body. Two chutes are symmetrically opened on both sides of the side plates.

The balls are in rolling connection with the chutes.

[0007] As a preferred embodiment, the sliding assembly includes first slide rails symmetrically and fixedly connected to the bottom of the inner wall of the switch cabinet body. Second slide rails are fixedly connected to one ends of the tops of the first slide rails. Wedge-shaped members are rotatably connected to the inner sides of the second slide rails.

[0015] In the present utility model, by pushing the trolley into the interior of the switch cabinet body, under the cooperation of the sliding assembly, the lower baffle plate will be pushed to turn upwards, thereby driving the lower sprocket to rotate. Under the cooperation of the sprocket and the chain, the lower chain is driven to rotate. With the cross arrangement of the connecting rods, the upper chain is driven to rotate in the opposite direction relative to the lower chain, and then the upper sprocket is driven to rotate in the opposite direction, thereby driving the upper baffle plate to turn downwards, realizing the synchronous turning of the two baffle plates to block the live area, reducing the electric shock risk caused by the operator accidentally touching the live area.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0024] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments

[0025] Embodiment 1

[0026] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, the utility model provides a technical solution: a power distribution cabinet for a strong magnetic field, which includes a switch cabinet body 1, a live area 22, a sliding component and a linkage component. The sliding component and the linkage component are both arranged inside the switch cabinet body 1. The linkage component includes two first rotating shafts 4 symmetrically arranged inside the switch cabinet body 1. A baffle 6 is fixedly connected to the outer periphery of the first rotating shaft 4. Sprockets 5 are fixedly connected to the outer peripheries of both ends of the first rotating shaft 4. Chains 9 are arranged on the outer peripheries of the sprockets 5. The sprockets 5 are meshed and connected with the corresponding chains 9. Connecting pieces 10 are fixedly connected to the bottoms of the chains 9. Connecting rods 11 are fixedly connected to the bottoms of the connecting pieces 10. The connecting rods 11 are arranged in a cross manner.

[0027] In this embodiment, by pushing the trolley into the inside of the switch cabinet body 1, with the cooperation of the sliding component, the lower baffle 6 will be pushed to turn upwards, thereby driving the lower sprocket 5 to rotate. With the cooperation of the sprocket 5 and the chain 9, the lower chain 9 is driven to rotate. With the cross arrangement of the connecting rods 11, the upper chain 9 is driven to rotate in the opposite direction relative to the lower chain 9, and then the upper sprocket 5 is driven to rotate in the opposite direction, thereby driving the upper baffle 6 to turn downwards, realizing the synchronous turning of the two baffles 6 to block the live area 22, reducing the electric shock risk caused by the operator accidentally touching the live area 22. At the same time, this setting also avoids the trolley touching the live area 22 during the process of entering and exiting, increasing the safety of operation.

[0028] Embodiment 2

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown in the figure, side plates 3 are fixedly connected to both sides of the inner wall of the switch cabinet body 1. Two sliding grooves 8 are symmetrically formed on both sides of each side plate 3. Two support shafts 7 are fixedly connected to one side of the baffle 6. The ends of the support shafts 7 extend into the corresponding sliding grooves 8 and are rotatably connected with balls. The balls are in rolling connection with the sliding grooves 8. The sliding grooves 8 adopt an arc-shaped structure, which can better cooperate with the balls for sliding, enabling the baffle 6 to turn at a larger angle and providing better shielding.

[0030] The sliding assembly includes first slide rails 12 symmetrically and fixedly connected to the bottom of the inner wall of the switch cabinet body 1. One end of the top of each first slide rail 12 is fixedly connected with a second slide rail 13. Wedge-shaped members 14 are rotatably connected to the inner sides of the second slide rails 13. One side of each wedge-shaped member 14 is rotatably connected with a first connecting rod 15. Second rotating shafts 16 are rotatably connected through the interiors of the second slide rails 13. Second connecting rods 17 are rotatably connected to the outer sides of the second rotating shafts 16. The ends of the second connecting rods 17 are rotatably connected to one side of the corresponding first connecting rod 15. Fixed blocks 18 are fixedly connected to one side of each second slide rail 13. Torsion springs 19 are fixedly connected between the outer sides of the fixed blocks 18 and one side of the second connecting rods 17. Connecting rods 20 are fixedly connected to the ends of the second rotating shafts 16. Support rods 21 are rotatably connected to the ends of the connecting rods 20. The tops of the support rods 21 are rotatably connected to one side of the bottom of the baffle 6. Through the cooperation of the trolley and the wedge-shaped member 14, the wedge-shaped member 14 is driven to rotate, thereby driving the first connecting rod 15 to rotate, further driving the second connecting rod 17 to rotate, thereby driving the second rotating shaft 16 to rotate, and finally realizing the turning of the baffle 6. The setting of the torsion spring 19 also makes the flipping movement of the baffle 6 smoother and reduces the possibility of damage to the baffle 6 caused by instantaneous large forces.

[0031] Inside the switchgear body 1, a partition 2 is fixedly connected. The live area 22 is arranged below the partition 2 and between two side plates 3. A second cabinet door 24 and a first cabinet door 23 are sequentially rotatably connected to the outside of the switchgear body 1. Heat dissipation holes 25 are evenly arranged inside the first cabinet door 23. The side plates 3, the first slide rail 12, the second slide rail 13, and the baffle 6 are all made of 304 non-magnetic stainless steel. 304 non-magnetic stainless steel is a special type of stainless steel material. Under most conditions, its magnetism is very weak and can even be regarded as non-magnetic. This is due to its special chemical composition, which is mainly an alloy composed of iron, nickel, chromium, and a small amount of other elements. In this material, the interaction between elements cancels out most of the magnetism, making its reactivity to the magnetic field very small. Under a strong magnetic field, ordinary metals may be affected by the magnetic force and even become magnetized, which may cause the movement of the internal parts of the switchgear body 1 to be blocked, resulting in jamming or unstable operation. However, using 304 non-magnetic stainless steel will not have this problem. Due to its low magnetism, the magnetic field has little effect on it. Therefore, all operations inside the device will not be affected and can maintain normal operation. In short, the low magnetism or non-magnetism of 304 non-magnetic stainless steel provides the device with the ability to work stably in a strong magnetic field environment. Whether it is the entry and exit of the trolley or the movement of the connecting rod and chain, it will not be interfered by the magnetic field, thus ensuring the stability of the device. At the same time, using 304 non-magnetic stainless steel for the side plates 3, the first slide rail 12, the second slide rail 13, and the baffle 6 ensures the anti-corrosion and anti-oxidation ability of the device, maintains the stable operation of the device, avoids the performance degradation or damage of the device caused by environmental factors, and at the same time can avoid the jamming of the trolley entry and exit caused by the interference of the strong magnetic field;

[0032] This device needs to work in a strong magnetic field environment. The structures and materials set to prevent strong magnetic field interference have the following benefits:

[0033] 1. Ensure the normal operation of the device: Strong magnetic field interference may affect the internal circuits and components of electronic devices, resulting in a decline in device performance or even failure. By preventing strong magnetic field interference, the normal operation of the device can be ensured, and the reliability and stability of the device can be improved.

[0034] 2. Improve production efficiency: In a production environment, the normal operation of the device is one of the key factors to ensure production efficiency. Preventing strong magnetic field interference can avoid equipment downtime and failures caused by interference, ensure the continuous and stable operation of the production line, and improve production efficiency.

[0035] 3. Ensure data security: In the field of information technology, strong magnetic field interference may cause data transmission errors or losses, posing a threat to data security. By preventing strong magnetic field interference, the integrity and security of data can be ensured, and the normal operation of the information system and the accurate transmission of data can be ensured.

[0036] 4. Reduce maintenance costs: Damage or failure of equipment caused by strong magnetic field interference requires repair or replacement, which will increase maintenance costs and downtime. By preventing strong magnetic field interference, the maintenance costs and repair frequency of equipment can be reduced, the downtime of the production line can be minimized, and thus the operating costs of the enterprise can be lowered.

[0037] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
