Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering. More specifically, the present invention relates to a large-scale distribution cabinet for building construction that improves power distribution safety. Background Art

[0002] A distribution cabinet refers to a device specifically designed for construction sites to distribute and control electric energy. In building construction, the distribution cabinet plays a crucial role. It can not only ensure the stability and safety of power supply but also effectively manage and distribute electric energy to meet the power requirements of different construction equipment. Inside the distribution cabinet, various electrical components are usually equipped, such as circuit breakers, contactors, fuses, etc. These components work together to achieve the distribution, control, and protection of electric energy. In addition, the distribution cabinet has good protection performance and can resist the invasion of dust, moisture, and other harsh environments on the internal electrical components, ensuring the stable operation of the distribution cabinet in a complex and changeable construction environment.

[0003] According to the patent document: CN118431938B, a large-scale municipal distribution cabinet with efficient heat dissipation is disclosed, including a base, a cabinet body, a cabinet door, and a top seat. A plurality of heat dissipation units are installed in the top seat. In the large-scale distribution cabinet of the present application, by adjusting the positions of the sliding seat and the mounting seat, two-dimensional adjustment of the fan unit on the plane can be achieved. Rotating the rotating rod tightens the pull rope, so that the position of the fan unit can be fixed, and the fan unit can be moved to any position where heat dissipation air flow is required. The pressure sensor can detect that the pull rope is in a relaxed state, and then the acoustic and optical alarm unit alarms, so as to remind maintenance in time to resume heat dissipation work. The temperature sensor can detect the temperature inside the cabinet body, so that when the temperature is too high, the acoustic and optical alarm unit can alarm to remind the operator to take corresponding measures in time.

[0004] Inside the distribution cabinet, power distribution and control are usually carried out through a main switch plus multiple sub-switches. Each sub-switch corresponds to a specific circuit or device and can be independently turned on or off for refined management of power supply. Generally, when the voltage or pressure is too high or in the case of internal components, the sub-switch will automatically trip to cut off the power supply of the corresponding circuit or device, thus protecting the circuit and device from damage. However, in the case of serious damage, the sub-switch of the corresponding out-of-control component may explode due to being unable to withstand excessive current, which will affect the safety of the surrounding circuits and even cause serious consequences such as a fire. Summary of the Invention

[0005] In order to overcome the above defects of the prior art, the present invention provides a large-scale power distribution cabinet for building construction that improves power distribution safety. The technical problem to be solved by the present invention is that generally when the voltage pressure is too high or in the case of internal components, the secondary switch will automatically trip, cutting off the corresponding circuit or equipment power supply, thereby protecting the circuit and equipment from damage. However, in the case of serious damage, the secondary switch of the corresponding out-of-control component may explode due to being unable to withstand excessive current, which will then affect the safety of the surrounding circuits and even cause serious consequences such as fires.

At the front end of the electric push rod 2216, there is a fixed connection with an inverted L-shaped push and pull block 2225. At the rear side of the inverted L-shaped push and pull block 2225, there is a fixed connection with a U-shaped push rod 2223. The top of the rear side of the U-shaped push rod 2223 is in contact with the bottom of the arc-shaped switch control block 2212. The left and right sides of the U-shaped push rod 2223 are respectively slidably connected to the inner walls of the two concave-shaped guide blocks 2218. The left and right sides of the two U-shaped push rods 2223 are rotatably connected to the top inside of the two V-shaped rotating rods 2222. At the rear sides of the left and right sides of the U-shaped push rod 2223, there are fixed connections with spring connection blocks 2224. At the front ends of the two groups of second springs 2220, there are fixed connections with the rear sides of the two spring connection blocks 2224. At the front side of the inner wall of the chute plate 224, there is a fixed connection with a third spring 2228. At the rear end of the third spring 2228, there is a fixed connection with a push and pull slider 2226. The outer wall of the push and pull slider 2226 is slidably connected to the inner wall of the spring connection block 2224. At the front sides of the left and right sides of the push and pull slider 2226, there are fixed connections with side sliding rods 2227. The outer sides of the two side sliding rods 2227 extend to the left and right sides of the chute plate 224 and are rotatably connected to the sides away from the rotating rod 229 inside the two second rotating rods 2210. At the rear side of the push and pull slider 2226, there is a rotatable connection with a V-shaped male connector control rotating rod 2229. At the rear side of the outer wall of the V-shaped male connector control rotating rod 2229, it extends to the rear side of the outer wall of the chute plate 224 and is fixed with a male connector 2230. The middle part of the outer wall of the V-shaped male connector control rotating rod 2229 is rotatably connected to the inside of the hinge block 225. Each of the multiple energized female contact elements 3 includes an energized element 31. At the top of each of the multiple energized elements 31, there is a fixed connection with an energized element female connecting pipe 32. At the bottom of the outer walls of each of the multiple energized element female connecting pipes 32, there is a fixed connection with an energized element guide block 33. The outer wall of the explosion-proof chamber 4 is fixed to the rear side inside the two groups of Z connecting rods 214. The bottom of the energized element 31 is slidably connected to the bottom of the rear side of the L-shaped connecting plate 222. The rear sides of the left and right sides of the energized element 31 are respectively rotatably connected to the bottom inside the two V-shaped rotating rods 2222. The two sides of the energized element guide block 33 are slidably connected to the inside of the two top Z connecting rods 214;

[0033] When the gate needs to be opened, first, the staff can pull up the arc switch control block 2212 to rotate around the arc switch control block hinge block 2211. This rotation action is transmitted to the rotating rod 229 and the second rotating rod 2210 through the third rotating rod 2217 and the T-shaped push-pull block 228, thereby causing the side-sliding rod 2227 and the push-pull slider 2226 to slide within the chute plate 224. As the push-pull slider 2226 moves forward, the V-shaped male connector control rotating rod 2229 rotates accordingly, causing the male connector 2230 to be docked with the corresponding energized component female connecting pipe 32, completing the circuit closure, and then starting to conduct electricity. At the same time, the rotation of the arc switch control block 2212 also stretches the spring 2213. After the closure is completed, at this time, the bottom of the front side of the arc switch control block hinge block 2211 is stuck on the top of the U-shaped push-pull rod 2223, ensuring the stable closure of the circuit;

[0034] When there is an overheat or overload situation that requires tripping and power-off, at this time, the electric push rod 2216 is activated to push the inverted L-shaped push-pull block 2225 to move forward. The inverted L-shaped push-pull block 2225 drives the U-shaped push-pull rod 2223 to move forward. The forward movement of the U-shaped push-pull rod 2223 causes the top of it to leave the bottom of the front side of the arc switch control block hinge block 2211. At this time, under the resilience of the spring 2213, the arc switch control block 2212 rotates reversely around the arc switch control block hinge block 2211. This reverse rotation action is also transmitted to the side-sliding rod 2227 and the push-pull slider 2226 through the third rotating rod 2217, the T-shaped push-pull block 228, the rotating rod 229 and the second rotating rod 2210, causing the push-pull slider 2226 to slide reversely within the chute plate 224, and then driving the V-shaped male connector control rotating rod 2229 to rotate reversely, disconnecting the male connector 2230 from the energized component female connecting pipe 32, completing the circuit disconnection and stopping the conduction of electricity. At the same time, the forward movement of the U-shaped push-pull rod 2223 drives the two V-shaped rotating rods 2222 to rotate around the V-shaped rotating rod connecting rod 2221. The rotation of the V-shaped rotating rods 2222 causes the energized female connecting component 3 at the inner bottom of it to move backward to the inner wall of the explosion-proof bin 4. The explosion-proof bin 4 can isolate and protect dangerous elements such as electric arcs and sparks generated by overheat and overload, improving the safety performance of the distribution cabinet;

[0035] Furthermore, in order to prevent an electric arc from being generated between the male connector 2230 and the energized component female connecting pipe 32 during the tripping and power-off process, the present invention is provided with an arc extinguishing device on the contact surface between the male connector 2230 and the energized component female connecting pipe 32. The arc extinguishing device includes an arc extinguishing piece provided on the male connector 2230 and an arc extinguishing groove provided on the energized component female connecting pipe 32. When the male connector 2230 is docked with the energized component female connecting pipe 32, the arc extinguishing piece is inserted into the arc extinguishing groove. When tripping and power-off is required, the cooperation between the arc extinguishing piece and the arc extinguishing groove can quickly stretch and extinguish the generated electric arc, further improving the safety performance of the distribution cabinet.

[0036] Working principle of the present invention: When it is necessary to open the gate, first, the staff can pull up the arc switch control block 2212 to rotate around the arc switch control block hinge block 2211. This rotation action is transmitted to the rotating rod 229 and the second rotating rod 2210 through the third rotating rod 2217 and the T-shaped push-pull block 228, thereby causing the side-sliding rod 2227 and the push-pull slider 2226 to slide in the chute plate 224. As the push-pull slider 2226 moves forward, the V-shaped male joint control rotating rod 2229 rotates accordingly, enabling the male joint 2230 to be docked with the corresponding energized component female connecting pipe 32, completing the closing of the circuit, and then starting to conduct electricity. At the same time, the rotation of the arc switch control block 2212 also stretches the spring 2213. After the closing is completed, at this time, the bottom of the front side of the arc switch control block hinge block 2211 is stuck on the top of the U-shaped push-pull rod 2223. When there is an overheat or overload and it is necessary to trip and cut off the power, at this time, the electric push rod 2216 is activated to push the inverted L-shaped push-pull block 2225 to move forward. The inverted L-shaped push-pull block 2225 drives the U-shaped push-pull rod 2223 to move forward. The forward movement of the U-shaped push-pull rod 2223 causes the top of it to leave the bottom of the front side of the arc switch control block hinge block 2211. At this time, under the resilience of the spring 2213, the arc switch control block 2212 rotates in the reverse direction around the arc switch control block hinge block 2211. This reverse rotation action is also transmitted to the side-sliding rod 2227 and the push-pull slider 2226 through the third rotating rod 2217, the T-shaped push-pull block 228, the rotating rod 229 and the second rotating rod 2210, causing the push-pull slider 2226 to slide in the reverse direction in the chute plate 224, and then driving the V-shaped male joint control rotating rod 2229 to rotate in the reverse direction, disconnecting the male joint 2230 from the energized component female connecting pipe 32, completing the disconnection of the circuit, and stopping the conduction of electricity. At the same time, the forward movement of the U-shaped push-pull rod 2223 drives the two V-shaped rotating rods 2222 to rotate around the V-shaped rotating rod connecting rod 2221. The rotation of the V-shaped rotating rods 2222 causes the energized female connecting component 3 at the inner bottom of it to move backward to the inner wall of the explosion-proof bin 4.
