Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more particularly to a safety power distribution cabinet. Background Technology

[0002] As the final stage equipment in a power distribution system, the distribution cabinet plays a crucial role in protecting, monitoring, and controlling the loads. Because it often controls multiple loads, it requires excellent heat dissipation and fire resistance (extinguishing) performance. However, existing distribution cabinets typically extinguish fires by injecting a gaseous extinguishing agent (usually carbon dioxide) into the cabinet. If the cabinet remains open to the outside environment, the gaseous extinguishing agent can easily dissipate, allowing air to enter and potentially reignite the fire. Conversely, if the cabinet remains closed, the internal pressure can rise, lowering the ignition point of combustibles and contributing to combustion. Furthermore, the continued increase in pressure can cause the cabinet to remain under high pressure for extended periods, posing a significant safety hazard and highlighting the shortcomings of current technology. Summary of the Invention

[0003] The purpose of this invention is to provide a safe power distribution cabinet to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A safety-type power distribution cabinet includes a cabinet body, mounting plates, cabinet doors, a water tank, and wiring channels. Vertical mounting plates are installed on the front and rear sides of the inner wall of the cabinet, and cabinet doors are hinged to both the front and rear sides. The cabinet doors can be locked to the cabinet body, and the joint between the doors and the cabinet body remains sealed after locking. A water tank is installed on the top of the cabinet body, and multiple wiring channels pass through it. A vertical upper discharge cylinder is fixed to the center of the top of the water tank, and multiple heat dissipation fins are fixed to both the left and right ends. The bottom of each heat dissipation fin is fixed to the bottom of the water tank. Each heat dissipation fin on the left and right sides of the water tank is fixed with a baffle. The upper part of each baffle is fixed to the opposite ends of the heat dissipation fins on the left and right sides of the water tank, and the bottom of each baffle is fixed to the heat dissipation fins on the left and right sides of the water tank. The bottom end is fixed. After the two baffles and heat dissipation fins are fixed, they together with the water tank form multiple right-angled cavities. Horizontal air extraction cylinders are fixed to the upper part of the two baffles. Exhaust fans are fixed inside the two air extraction cylinders. Electric cooling devices are fixed to the upper left and upper right parts of the water tank. A vertical lower discharge cylinder is fixed to the bottom of the water tank. A sealing plug is fixed to the bottom of the inner wall of the upper discharge cylinder. The sealing plug is slidably connected to the vertical upper exhaust cylinder. An upper one-way valve is fixed to the upper part of the inner wall of the upper exhaust cylinder, and a vertical lower exhaust cylinder is fixed to the bottom. A floating part is fixed to the outer wall of the upper exhaust cylinder. The lower exhaust cylinder is slidably connected to the lower discharge cylinder. The water tank contains condensed peanut oil blocks and ice blocks. This distribution cabinet is also equipped with a fire extinguishing section.

[0005] Based on the above technical solution, the fire extinguishing component includes a support frame, limiting plates, clamping plates, compression springs, tension springs, airbags, air inlet pipes, air vent pipes, lower one-way valves, exhaust pipes, middle one-way valves, a collection cylinder, a guide hopper, a guide cylinder, a discharge trough, and a copper mesh. Vertical support frames are fixed to the left and right sides of the cabinet. Limiting plates are slidably connected vertically to the upper and lower parts of each of the two support frames. Vertical clamping plates are slidably connected to the front and rear parts of each of the two support frames. A compression spring is fixed between each limiting plate and the support frame. A tension spring is fixed between the two clamping plates within each of the two support frames. Each limiting plate is positioned between the clamping plates at the front and rear of the support frame under the elastic repulsive force of the compression spring. The two clamping plates within each of the two support frames are... The elastic tension of the spring counteracts the limiting plate. Two columnar airbags are placed inside the two support frames. Air inlet pipes are fixed to adjacent ends of the two airbags, and vent pipes are fixed to opposite ends. Each vent pipe is equipped with a lower one-way valve. Two horizontal exhaust pipes are fixed to the upper front of the water tank. Each exhaust pipe is equipped with a middle one-way valve. A collection cylinder is fixed to the upper middle part of the cabinet. The bottom of the collection cylinder is closed, and a funnel-shaped guide bucket is fixed to the upper part. The collection cylinder is made of metal. A vertical guide cylinder is fixed to the middle of the guide bucket. Multiple discharge slots penetrate the bottom of the guide cylinder near the guide bucket. Multiple vertical copper meshes are fixed to the bottom of the collection cylinder. The cabinet is also equipped with a main one-way valve.

[0006] Based on the above technical solution, the exhaust fan and electric refrigeration device are externally powered and controlled. The refrigeration part of the electric refrigeration device is located inside the water tank, while its heat dissipation part is outside the cabinet. The electric refrigeration device is waterproof. The peanut oil condensed in the water tank is below the ice. The upper one-way valve only allows fluid to pass from bottom to top. The buoyancy of the float allows it to float on the surface of the liquid peanut oil while simultaneously driving the upper and lower exhaust pipes. The lower exhaust pipe is connected to the upper exhaust pipe. The diameter of the air cylinder is larger than that of the upper exhaust cylinder, and the diameter of the guide cylinder is smaller than that of the lower exhaust cylinder. The inner cavities of the air inlet pipe and the air outlet pipe are both connected to the inner cavity of the air bag. The two air inlet pipes are connected to the exhaust pipe through an external pipe. The inner cavity of the exhaust pipe is connected to the inner cavity of the water tank. The lower one-way valve only allows fluid to be discharged from the air bag through the air outlet pipe, and the middle one-way valve only allows fluid to be discharged from the water tank through the exhaust pipe. The collection cylinder is located directly below the lower exhaust cylinder, and the main one-way valve only allows fluid to be discharged from the cabinet to the outside.

[0007] Compared with the prior art, the present invention has the following advantages: When in use, the electric refrigeration device and exhaust fan can cool and dissipate heat from the electrical components inside the cabinet. By covering water with peanut oil, the water absorbs heat and quickly vaporizes to generate water vapor, which is then discharged into the air bladder. As the air bladder inflates, it compresses the gas inside the cabinet, thereby reducing the total oxygen content and releasing heat. The heated copper mesh also absorbs oxygen, further reducing the total oxygen content. When the water in the tank completely vaporizes, the water vapor in the air bladder is discharged under the pressure of the clamps, reducing the air pressure inside the cabinet and increasing the ignition point of flammable materials. Furthermore, as the water vaporizes, the lower exhaust pipe and lower discharge pipe are no longer sealed, allowing the peanut oil to enter the collection cylinder and burn rapidly, further consuming oxygen inside the cabinet and simultaneously reducing the air pressure, thus further increasing the ignition point of flammable materials.

[0008] This invention achieves multiple flame-retardant and fire-extinguishing effects by dissipating heat from inside the cabinet, lowering the temperature inside the cabinet, and repeatedly reducing the oxygen content and air pressure inside the cabinet to increase the ignition point of flammable materials, thereby improving safety.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-6As shown, a safety distribution cabinet includes a cabinet body 1, mounting plates 2, cabinet doors 3, a water tank 4, and wiring channels 5. Vertical mounting plates 2 are installed on the front and rear sides of the inner wall of the cabinet body 1, and cabinet doors 3 are hinged to both the front and rear sides. The cabinet doors 3 can be locked to the cabinet body 1, and the joint between the cabinet doors 3 and the cabinet body 1 remains sealed. A water tank 4 is installed on the top of the cabinet body 1, and multiple wiring channels 5 pass through it. A vertical upper discharge cylinder 6 is fixed to the center of the top of the water tank 4. Furthermore, multiple heat dissipation fins 7 are fixed at both the left and right ends. The bottom of each heat dissipation fin 7 is fixed to the bottom of the water tank 4. Each heat dissipation fin 7 on the left and right sides of the water tank 4 is fixed with a baffle 8. The upper parts of the two baffles 8 are fixed to the opposite ends of the heat dissipation fins 7 on the left and right sides of the water tank 4, and the bottoms are fixed to the bottom ends of the heat dissipation fins 7 on the left and right sides of the water tank 4, respectively. After the two baffles 8 are fixed to the heat dissipation fins 7, they together with the water tank 4 form multiple right angles. The right-angled cavity 9 allows air to fully contact the heat dissipation fins 7 when drawn in by the exhaust fan 11 before being discharged from the suction cylinder 10, thereby improving the heat exchange effect with the heat dissipation fins 7. Horizontal suction cylinders 10 are fixed to the upper parts of the two baffles 8, and exhaust fans 11 are fixed inside the two suction cylinders 10. Electric cooling devices 12 are fixed to the upper left and upper right parts of the water tank 4, and a vertical lower discharge cylinder 13 is fixed to the bottom of the water tank 4. A sealing plug 14 is fixed to the bottom of the inner wall of the discharge cylinder 6. The sealing plug 14 is slidably connected to a vertical upper exhaust cylinder 15. An upper one-way valve 16 is fixed to the upper part of the inner wall of the upper exhaust cylinder 15, and a vertical lower exhaust cylinder 17 is fixed to the bottom. A floating part 18 is fixed to the outer wall of the upper exhaust cylinder 15. The lower exhaust cylinder 17 is slidably connected to the lower discharge cylinder 13. The water tank 4 contains condensed peanut oil blocks and ice blocks. This power distribution cabinet is also equipped with a fire extinguishing section 19.

[0018] The fire extinguishing component 19 includes a support frame 20, a limiting plate 21, a clamping plate 22, a compression spring 23, a tension spring 24, an airbag 25, an air inlet pipe 26, an air vent pipe 27, a lower one-way valve 28, an exhaust pipe 29, a middle one-way valve 30, a collection cylinder 31, a guide hopper 32, a guide cylinder 33, a discharge trough 34, and a copper mesh 35. Vertical support frames 20 are fixed to the left and right sides of the cabinet 1. Limiting plates 21 are slidably connected to the upper and lower parts of each of the two support frames 20. Each of the front and rear parts of the support frame 20 is slidably connected to a vertical clamping plate 22. A compression spring 23 is fixed between each of the limiting plates 21 and the support frame 20. A tension spring 24 is fixed between the two clamping plates 22 within each of the two support frames 20. Under the elastic repulsive force of the compression spring 23, each limiting plate 21 is positioned between the clamping plates 22 at the front and rear parts of the support frame 20. Under the elastic tension of the tension spring 24, the two clamping plates 22 within each of the two support frames 20 resist the limiting plates 21. This prevents the clamps 22 from getting too close to each other. Each of the two support frames 20 contains a columnar airbag 25. An air inlet pipe 26 is fixed to the adjacent middle ends of each airbag 25, and a vent pipe 27 is fixed to the opposite ends. Each vent pipe 27 is equipped with a lower one-way valve 28. Two horizontal exhaust pipes 29 are fixed to the upper front end of the water tank 4. Each exhaust pipe 29 is equipped with a middle one-way valve 30. A collection cylinder 31 is fixed to the upper middle part of the cabinet 1. The bottom of the collection cylinder 31 is closed, and a funnel-shaped guide hopper 32 is fixed to the upper part. The funnel-shaped guide hopper 32 guides and collects the flowing peanut oil during use. The collection cylinder 31 is made of metal. A vertical guide cylinder 33 is fixed to the middle of the guide hopper 32. Multiple discharge slots 34 penetrate the bottom of the guide cylinder 33 near the guide hopper 32. Multiple vertical copper meshes 35 are fixed to the bottom of the collection cylinder 31. The cabinet 1 is also equipped with a main one-way valve 36.

[0019] The exhaust fan 11 and the electric refrigeration device 12 are connected to an external power supply and controller. The refrigeration part of the electric refrigeration device 12 is located inside the water tank 4, and its heat dissipation part is outside the cabinet 1. The electric refrigeration device 12 is waterproof. The peanut oil condensed in the water tank 4 is below the ice. Since the thermal conductivity of peanut oil is stronger than that of water, the heat-conducting fins 7 can better exchange heat with the condensed peanut oil, ice, and electric refrigeration device. The upper one-way valve 16 only allows fluid to pass from bottom to top. The buoyancy of the float 18 allows it to float on the surface of the liquid peanut oil while driving the upper exhaust pipe 15 and the lower exhaust pipe 17. The lower exhaust pipe 17 is connected to the upper exhaust pipe 15. The diameter of the exhaust pipe 17 is larger than that of the upper exhaust pipe 15, and the diameter of the guide pipe 33 is smaller than that of the lower exhaust pipe 17, so that the flame can be better guided by the lower exhaust pipe 17 and the flame spread is avoided. The inner cavities of the air inlet pipe 26 and the air outlet pipe 27 are connected to the inner cavity of the airbag 25. The two air inlet pipes 26 are connected to the exhaust pipe 29 through external pipes. The inner cavity of the exhaust pipe 29 is connected to the inner cavity of the water tank 4. The lower one-way valve 28 only allows fluid to be discharged from the airbag 25 through the air outlet pipe 27. The middle one-way valve 30 only allows fluid to be discharged from the water tank 4 through the exhaust pipe 29. The collection cylinder 31 is located directly below the lower exhaust pipe 17. The main one-way valve 36 only allows fluid to be discharged from the cabinet 1 to the outside.

[0020] The working principle of this invention is as follows: When in use, electrical components are installed on opposite ends of the two mounting plates 2. Power lines and signal lines are connected to electrical components through the wire groove 5. Then, the remaining gaps in the wire groove 5 are filled with filler to ensure a sealing effect. In the initial state, the airbag 25 remains deflated, and the clamping plate 22 is abutted by the limiting plate 21.

[0021] During normal use, both the electric refrigeration device 12 and the exhaust fan 11 are in normal working condition. At this time, the peanut oil and ice are in a stable condensed state. The two rotating exhaust fans 11 will continuously draw air from the air extraction cylinder 10 and discharge it to the left and right sides of the cabinet 1. That is, they will draw air from each passage 9 and discharge it to the left and right sides of the cabinet 1. During this process, the hot air formed by the heat conduction of the electrical components can enter each passage 9 and conduct heat with the heat dissipation fins 7, thereby gradually cooling it down and finally discharging it from the air extraction cylinder 10. This will cool the electrical components and ensure their normal operation.

[0022] When electrical components catch fire, as described above, the excessive heat generated by the components will cause the condensed peanut oil and ice to melt into a liquid state. Since the density of peanut oil is less than that of water, the peanut oil will float on the water surface. At this time, due to the buoyancy of the float 18, the upper exhaust pipe 15 and the sealing plug 14 are in a sealed state, and the lower exhaust pipe 17 and the lower discharge pipe 13 are in a sealed state. Due to the sealing effect of the peanut oil on the water, the water temperature will rise rapidly and generate a large amount of water vapor. As the air pressure in the water tank 4 increases, the water vapor will be discharged into the airbag 25 through the exhaust pipe 29 and the one-way valve 30, causing the airbag 25 to gradually inflate and expand. As the airbag 25 inflates, it gradually compresses and repels the cabinet. Excess air inside cabinet 1 will be discharged through the main one-way valve 36, thereby reducing the total amount of gas inside cabinet 1 and thus reducing the total amount of combustion-supporting gas (oxygen). The burning electrical components will also heat the copper mesh 35, causing it to react with and absorb oxygen from the air, further reducing the total amount of oxygen and achieving a flame-retardant (fire-extinguishing) effect. As the electrical components continue to burn, when the water in water tank 4 is completely vaporized, the air bladder 25 fills to its maximum columnar state, pushing the upper and lower limiting plates 21 of the support frame 20 away from each other. This allows the clamping plates 22 to disengage from the limiting plates 21, and under the elastic tension of the tension spring 24, the clamping plates 22 will then come closer together. When the airbag 25 is compressed, the fluid flow is controlled by the lower one-way valve 28 and the middle one-way valve 30. After being compressed, the water vapor inside the airbag 25 can only be discharged through the vent pipe 27 and the lower one-way valve 28, causing the airbag 25 to gradually deflate. As the airbag 25 deflates, the air pressure inside the cabinet 1 gradually decreases, thereby increasing the ignition point of the flammable materials inside the cabinet 1, achieving a flame-retardant (fire-extinguishing) effect. The vaporization of liquid water and the eventual discharge of water vapor from the vent pipe 27 reduce the heat inside the cabinet 1, thus lowering the temperature inside the cabinet 1 and achieving a cooling and fire-extinguishing effect. When the water in the water tank 4 completely evaporates into water vapor, due to the reduction in the volume of liquid water, the mixture of liquid water and peanut oil... The liquid level decreases, causing the float 18, upper exhaust pipe 15, upper check valve 16, and lower exhaust pipe 17 to move downwards together. This eventually causes the lower exhaust pipe 17 to lose its sealing contact with the lower discharge pipe 13, while the upper exhaust pipe 15 remains in sealing contact with the sealing plug 14. This allows the peanut oil in the water tank 4 to be discharged from the lower discharge pipe 13 into the guide hopper 32, and further into the collection cylinder 31 through the discharge trough 34. The collection cylinder 31 becomes incandescent due to heat conduction from the burning electrical components and the heated copper mesh 35. This causes the peanut oil to burn rapidly upon entering the collection cylinder 31 and be discharged from the guide pipe 33. The flames discharged from the guide pipe 33 then flow upwards to the exhaust pipe 15.This causes the upper one-way valve 16 to open, ultimately releasing a large amount of heat through the upper exhaust pipe 15. During this process, the burning flame rapidly consumes the oxygen inside cabinet 1, thus achieving a flame-retardant (fire-extinguishing) effect on the electrical components. After the flame is exhausted, the further consumption of oxygen inside cabinet 1 causes the air pressure inside cabinet 1 to decrease again, thereby increasing the ignition point of flammable materials and enhancing the flame-retardant (fire-extinguishing) effect.

[0023] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
