Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a fireproof, high-safety power distribution cabinet. Background Technology

[0002] Distribution cabinets are an essential component of power systems, playing an irreplaceable role in the stable operation of electrical systems and the management of power equipment. They are widely used in residential facilities, factory buildings, and workshops, providing stable power support for production and daily life. To ensure the stable and safe operation of distribution cabinets, their fire-fighting and fire-prevention functions are particularly important.

[0003] In the existing technology, in the process of fire prevention and fire extinguishing of power distribution cabinets, inert gas is usually used to extinguish the fire in order to avoid secondary damage to the circuit. However, this method often faces challenges in practical applications. For example, the inert gas fire extinguishing system cannot release the inert gas quickly and efficiently, which may not be able to suppress the fire quickly and in time, thus delaying the best time to extinguish the fire and causing serious equipment damage and data loss. Utility Model Content

[0004] In view of the shortcomings of existing technology, this utility model provides a new type of fireproof and high-safety power distribution cabinet.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A fireproof, high-safety power distribution cabinet includes: a power distribution box; a modular power distribution unit fixedly connected inside the power distribution box; a gas box fixedly connected to the bottom of the modular power distribution unit; a threaded rod at the center of the bottom of the gas box; a sealing plate surrounding the threaded rod; an inert gas pipe slidably connected to the outside of the gas box; a sealed box fixedly connected to the side of the inert gas pipe away from the gas box; a fan blade with a threaded hole at the center of the inert gas pipe; symmetrical air inlets on the outside of the inert gas pipe; a sealed box ventilation opening on the surface of the sealed box; and a surface with... The distribution box has a corresponding ventilation opening for the sealed box. The distribution box is equipped with a detection and control mechanism for controlling the movement of the sealed box for fire prevention. When the detection mechanism detects smoke and temperature signals, it sends a start signal to the control mechanism, causing the control mechanism to control the sealed box to slide downwards. When the ventilation opening of the sealed box and the ventilation opening of the distribution box do not overlap, the segmented distribution box and the sealed box create a sealed space. The stored inert gas enters the sealed box from the air inlet. The threaded hole rotates through the threaded connection with the threaded rod. The fan blades rotate with the threaded hole to generate wind pressure. The wind pressure accelerates the inert gas from the air inlet into the sealed box.

[0006] The longitudinal distance between the ventilation openings of the sealed box should be greater than the longitudinal length of the ventilation openings of the sealed box.

[0007] The above plan further includes: The detection and control mechanism includes a motor and a sensor assembly. The motor is fixedly connected to a segmented power distribution box, and a fixing plate is provided at the output end of the motor. A sealed box is fixedly connected to the side of the fixing plate away from the motor. The sensor assembly is located inside the sealed box and is electrically connected to the motor. The segmented power distribution box is arranged longitudinally and horizontally to form a segmented power distribution compartment.

[0008] The subdivided power distribution room consists of at least two subdivided power distribution boxes that are tightly fixed together, and the ventilation openings of the power distribution boxes on the fixed connection surfaces are corresponding to ensure normal ventilation.

[0009] The distribution box is equipped with a dustproof panel, and a ventilation fan is fixedly connected to the side of the subdivided distribution room near the dustproof panel.

[0010] The location of the dustproof plate should correspond to the ventilation opening of the power distribution box on the side of the subdivided power distribution box.

[0011] The gas chamber has a rectangular slide opening at its top. A sealing plate is fixedly connected to the gas chamber, and the rectangle formed by the sealing plate is the same as the slide opening, with a certain distance between the sealing plate and the slide opening. When the detection mechanism does not detect smoke or temperature signals, the control mechanism is fixed in a certain position. At this time, the inert gas pipe and the sealing plate form a hollow rectangular prism, which together with the gas chamber forms a sealed inert gas chamber, which is filled with inert gas.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, when the detection and control mechanism is working, the sub-distribution boxes of the fire section automatically form a sealed space, which not only isolates the entry of external oxygen, but also isolates the fire section from other parts, effectively preventing the spread of fire. While the fire section is automatically sealed and extinguished, other sub-distribution boxes are normally ventilated, dissipated heat and prevented from dust, effectively reducing the fire hazard caused by the high temperature transmission from the fire section. At the same time, the inert gas is accelerated by the fan blades, which makes it act faster and more quickly, greatly enhancing the efficiency of inert gas release and improving the timeliness of gas extinguishing. The fire extinguishing material in this application is a safe, environmentally friendly, and highly efficient inert gas that will not damage the wiring or pollute the environment. This application uses a dustproof net and a ventilation fan in combination to enhance the ventilation and heat dissipation of the distribution cabinet while effectively reducing dust adsorption caused by the ventilation fan, thus greatly enhancing the safety of the distribution cabinet.

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figures 1-11As shown, this utility model is a fireproof, high-safety power distribution cabinet, which includes a power distribution box 1. A modular power distribution box 2 is fixedly connected inside the power distribution box 1. A gas box 9 is fixedly connected to the bottom of the modular power distribution box 2. A threaded rod 14 is provided at the center of the bottom of the gas box 9, and a sealing plate 17 is provided around the threaded rod 14. An inert gas pipe 11 is slidably connected to the outside of the gas box 9. A sealed box 8 is fixedly connected to the side of the inert gas pipe 11 away from the gas box 9. A threaded hole 13 is rotatably connected to the center of the inert gas pipe 11, and a fan blade 19 is fixedly connected to the threaded hole 13. Air inlets 10 are symmetrically opened on the outside of the inert gas pipe 11. A sealed box ventilation opening 7 is opened on the surface of the sealed box 8. 2. A distribution box ventilation port 5 corresponding to the sealed box ventilation port 7 is opened on the surface. The distribution box 1 is equipped with a detection and control mechanism for controlling the movement of the sealed box 8 for fire prevention. When the detection mechanism detects smoke and temperature signals, it will send a start pulse to the control mechanism, so that the control mechanism will start to control the sealed box 8 to slide downward. When the sealed box ventilation port 7 and the distribution box ventilation port 5 do not overlap, the segmented distribution box 2 and the sealed box 8 will form a sealed space. At this time, the stored inert gas enters the sealed box 8 from the air inlet 10. The threaded hole 13 rotates through the threaded connection with the threaded rod 14. The fan blade 19 rotates with the threaded hole 13 to generate wind pressure, which accelerates the inert gas from the air inlet 10 into the sealed box 8.

[0018] The detection and control mechanism includes a motor 3 and a sensor group 12. The motor 3 is fixedly connected to a block power distribution box 2. A fixing plate 6 is provided on the side of the motor 3 near the sealed box 8. The sealed box 8 is fixedly connected on the side of the fixing plate 6 away from the motor 3. The sensor group 12 is located inside the sealed box 8 and is electrically connected to the motor 3 through a control module commonly used in the art.

[0019] The sub-distribution boxes 2 are arranged longitudinally and horizontally to form the sub-distribution rooms. The distribution box 1 has a dustproof panel 18, and a ventilation fan 4 is fixedly connected to the side of the sub-distribution room closest to the dustproof panel 18. The gas box 9 has a slide opening 15 at its top, and a sealing plate 17 is fixedly connected to the gas box 9. The rectangle formed by the sealing plate 17 is the same as the slide opening 15, and there is a certain distance between the sealing plate 17 and the slide opening 15. When the detection mechanism does not detect smoke or temperature signals, the control mechanism is fixed in a certain position. The inert gas pipe 11 and the sealing plate 17 form a hollow rectangular prism, which, together with the gas box 9, forms an inert gas chamber 16. The operator fills the inert gas chamber 16 with inert gas.

[0020] The working principle of the fireproof high-safety distribution cabinet proposed in this utility model is as follows: Normally, the relative positions of the sealed box 8 and the gas box 9 are fixed by adjusting the distance between the motor 3 and the fixing plate 6, so that part of the inert gas pipe 11 is inside the sealing plate 17, and the air inlet 10 is at an appropriate position higher than the slide opening 15. The inert gas pipe 11 and the sealing plate 17 form a hollow rectangular prism, which, together with the gas box 9, forms an inert gas chamber 16. Workers fill the inert gas chamber 16 with inert gas. When a fire occurs, the sensor group 12 detects a smoke signal and immediately sends a working signal to the motor 3, causing the motor 3 to operate and push the sealed box 8 vertically downwards. When the sealed box ventilation opening 7 and the distribution box ventilation opening 5 have no overlap, the segmented distribution box 2 and the sealed box 9... The closed box 8 forms a sealed space, preventing the entry of external oxygen. At this time, the threaded hole 13 is threadedly connected to the threaded rod 14, and the air inlet 10 begins to enter the inert gas chamber 16 from top to bottom through the slide port 15. As the motor 3 continues to work, the air inlet 10 gradually enters the inert gas chamber 16 until it completely descends below the slide port 15. During the descent, the threaded hole 13 rotates through the threaded connection with the threaded rod 14, driving the fan blade 19 to rotate and generate wind pressure, accelerating the inert gas in the inert gas chamber 16 to enter the sealed space formed by the sub-distribution box 2 and the closed box 8, achieving the purpose of flame retardant fire extinguishing. Moreover, during the entire closed fire extinguishing process, the spread of fire is isolated, and it will not affect the normal operation of the power distribution modules in other sub-distribution boxes 2.

[0021] Example 2

[0022] like Figures 1-11 As shown, the distribution box 1 has a dustproof plate 18, the segmented distribution boxes 2 are arranged longitudinally and horizontally to form a segmented distribution room, and a ventilation fan 4 is fixedly connected to the side of the segmented distribution room near the dustproof plate 18.

[0023] The working principle of the fireproof high-safety distribution cabinet described in this embodiment is as follows: under normal circumstances, the relative positions of the distribution box ventilation port 5 and the sealed box ventilation port 7 are fixed by the motor 3, so that the corresponding positions of the distribution box ventilation port 5 and the sealed box ventilation port 7 are completely aligned. When the ventilation fan 4 is working, it generates wind pressure, which drives the outside air into the distribution cabinet for circulation. The dust in the air is blocked by the dustproof plate 18. The filtered air goes through the ventilation fan 4 to the sub-distribution box 2, and then through the distribution box ventilation port 5 to reach another sub-distribution box 2 and the distribution cabinet cavity, which achieves good ventilation and heat dissipation.

[0024] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model.
