Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a fireproof electrical automation control cabinet. Background Technology

[0002] An electrical automation control cabinet is a device that integrates various electrical equipment and automation control components, used to control, monitor, and protect electrical systems, industrial equipment, or processes.

[0003] Existing electrical automation control cabinets still require manual handling for fire prevention or extinguishing, posing a safety hazard.

[0004] The existing patent (publication number: CN216123226U) describes a fireproof electrical automation control cabinet. This utility model features a slider that slides within a first hole and is internally slidable. A first frame is installed at the top of the control cabinet. When the temperature and air pressure inside the control cabinet rise continuously, the first frame slides into the second frame, allowing dry powder extinguishing agent to fall into the control cabinet, thus facilitating the extinguishing of fires or reducing the possibility of fires inside the control cabinet. An L-shaped plate corresponding to a buzzer is installed at the bottom of the slider, so that when the temperature inside the control cabinet rises, the air pressure pushes the slider to activate the buzzer to alert nearby personnel.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, some existing fireproof electrical automation control cabinets only facilitate fire extinguishing inside the cabinet to achieve fire prevention. When other equipment outside the cabinet catches fire, the external fire source can easily bake the cabinet, causing damage to the internal components.

[0006] Therefore, a fireproof electrical automation control cabinet is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a fireproof electrical automation control cabinet, which can solve the problem that some existing fireproof electrical automation control cabinets can only achieve the purpose of fire prevention by extinguishing the fire inside the electrical automation control cabinet. When other equipment outside the electrical automation control cabinet catches fire, the external fire source can easily bake the electrical automation control cabinet, causing damage to the internal components.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fireproof electrical automation control cabinet, comprising a control cabinet body, a cabinet door and several control buttons, wherein a fire extinguishing tank is provided on the top of the control cabinet body, an external fire extinguishing mechanism is provided on the top of the fire extinguishing tank, and an internal fire extinguishing mechanism is provided inside the control cabinet body;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A fireproof electrical automation control cabinet includes a control cabinet body 1, a cabinet door 2 and several control buttons 3. A fire extinguishing tank 5 is installed on the top of the control cabinet body 1, an external fire extinguishing mechanism 6 is installed on the top of the fire extinguishing tank 5, and an internal fire extinguishing mechanism 4 is installed inside the control cabinet body 1.

[0031] The external fire extinguishing mechanism 6 includes several first discharge nozzles 601, two first temperature sensors 602, a ring pipe 603, a delivery pipe 604, and a first solenoid valve 605. The side of the first discharge nozzle 601 closest to the ring pipe 603 is fixedly connected to the ring pipe 603. The top of the delivery pipe 604 is fixedly connected to the bottom of the ring pipe 603. The first solenoid valve 605 is installed inside the delivery pipe 604. The side of the delivery pipe 604 closest to the fire extinguishing tank 5 is fixedly connected to the fire extinguishing tank 5. The top of the first temperature sensor 602 is fixedly connected to the bottom of the ring pipe 603.

[0032] Specifically, such as Figure 4 As shown, a fixing bracket 11 is fixedly connected to the inner wall of the ring pipe 603, and a fixing column 10 is fixedly connected to the bottom of the fixing bracket 11. The bottom of the fixing column 10 is fixedly connected to the top of the fire extinguishing tank 5.

[0033] In this embodiment: when a fire occurs in the external equipment of the control cabinet 1, the first temperature sensor 602 senses a sharp rise in the external ambient temperature of the control cabinet 1. The first temperature sensor 602 then transmits a signal to the built-in control system, causing the first solenoid valve 605 to open. The extinguishing agent in the fire extinguishing tank 5 enters the ring pipe 603 through the delivery pipe 604, and then sprays the extinguishing agent around the outside of the control cabinet 1 from the first discharge nozzle 601 on the ring pipe 603, forming a fire barrier to prevent the external fire source from baking and spreading to the control cabinet 1. The ring pipe 603 is stably installed on the top of the fire extinguishing tank 5 by the fixing bracket 11 and the fixing column 10. Since the first discharge nozzle 601 is inclined to the four sides of the ring pipe 603, it is convenient to increase the spray range of the extinguishing agent.

[0034] Specifically, such as Figure 3 As shown, the internal fire extinguishing mechanism 4 includes a second solenoid valve 401, a dual-pass pipe 402, a second temperature sensor 403, two fixed pipes 404, and several second discharge nozzles 405. The first solenoid valve 405 is installed inside the dual-pass pipe 402. The side of the dual-pass pipe 402 near the fixed pipe 404 is fixedly connected to the fixed pipe 404. The side of the second temperature sensor 403 near the fixed pipe 404 is fixedly connected to the fixed pipe 404. The side of the second discharge nozzle 405 near the fixed pipe 404 is fixedly connected to the fixed pipe 404.

[0035] Specifically, such as Figure 2 and Figure 6As shown, through holes 15 are provided on both sides of the top of the control cabinet 1, and the fixing tube 404 is fixedly connected to the inner wall of the through hole 15. The second temperature sensor 403 is located inside the control cabinet 1.

[0036] In this embodiment: when a fire occurs in the external electrical components inside the control cabinet 1, the second temperature sensor 403 located inside the control cabinet 1 detects a sharp rise in the internal temperature of the control cabinet 1. After the temperature rises to the set value, the built-in control system will open the second solenoid valve 401. The extinguishing agent enters the fixed pipe 404 from the fire extinguishing tank 5 through the double-pass pipe 402, and finally sprays into the control cabinet 1 through the second discharge nozzle 405 to extinguish the internal fire source. By tilting the second discharge nozzle 405 backward, the extinguishing agent can be easily sprayed onto the surface of the external electrical components inside the control cabinet 1 for fire extinguishing. The fixed pipe 404 is fixed inside the through hole 15, which makes it easy to install the fixed pipe 404 inside the control cabinet 1.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, exhaust vents 14 are provided on both sides of the control cabinet 1. A fixing ring 12 is provided inside the exhaust vent 14, and a dustproof net 7 is fixedly connected to the inner wall of the fixing ring 12.

[0038] Specifically, such as Figure 5 and Figure 7 As shown, a rubber ring 13 is fixedly sleeved on the surface of the fixing ring 12, and an annular groove 16 is provided on the inner wall of the vent hole 14, with the rubber ring 13 snapped into the inside of the annular groove 16.

[0039] Specifically, such as Figure 2 As shown, a support column 17 is fixedly connected to the bottom of the fire extinguishing tank 5. The bottom of the support column 17 is fixedly connected to the top of the control cabinet 1. There are several support columns 17, which are evenly distributed at the bottom of the fire extinguishing tank 5.

[0040] Specifically, such as Figure 2 As shown, an installation plate 8 is fixedly connected to the inner wall of the control cabinet 1, and a wire hole 9 is provided at the bottom of the control cabinet 1.

[0041] In this embodiment: when fire extinguishing is not required inside or outside the control cabinet 1, the dustproof net 7 can prevent dust from entering the control cabinet 1 through the exhaust port 14. When the control cabinet 1 catches fire, the extinguishing agent and gas discharged from the second exhaust nozzle 405 will impact the fine dustproof net 7. At this time, the rubber ring 13 deforms, causing the rubber ring 13 to separate from the annular groove 16, which allows the dustproof net 7 and the fixing ring 12 to separate from the exhaust port 14. The extinguishing agent and gas discharged from the second exhaust nozzle 405 can then be discharged from the exhaust port 14, preventing the control cabinet 1 from becoming too pressurized and causing danger. The fire extinguisher 5 is fixed to the top of the control cabinet 1 by the support column 17. The external electrical components are fixed to the front side of the mounting plate 8 by external screws. The external connecting wires are passed through the wire hole 9 into the control cabinet 1, and then the wire hole 9 is sealed with external sealant.

[0042] Working principle: When a fire occurs outside the control cabinet 1, the first temperature sensor 602 in the external fire extinguishing mechanism 6 will detect a sharp rise in ambient temperature. Once the temperature exceeds the set threshold, the first temperature sensor 602 will transmit a signal to the built-in control system, causing the first solenoid valve 605 to open. The extinguishing agent in the fire extinguishing tank 5 will enter the ring pipe 603 through the delivery pipe 604, and then be sprayed out of the first discharge nozzle 601 on the ring pipe 603 to the surrounding area outside the control cabinet 1, forming a fire barrier to prevent external fire sources from baking and spreading to the control cabinet 1. The ring pipe 603 is stabilized by the fixing bracket 11 and the fixing column 10. The first discharge nozzle 601 is fixedly installed on top of the fire extinguishing tank 5, and is tilted towards the periphery of the ring pipe 603 to increase the spray range of the extinguishing agent. When a fire occurs in the external electrical components inside the control cabinet 1, the second temperature sensor 403 detects a rapid rise in the internal temperature of the control cabinet 1. After the temperature rises to the set value, the built-in control system opens the second solenoid valve 401, and the extinguishing agent enters the fixed pipe 404 from the fire extinguishing tank 5 through the double-pass pipe 402, and finally sprays into the control cabinet 1 through the second discharge nozzle 405 to extinguish the internal fire. The second discharge nozzle 405 is tilted backward to facilitate the spraying of the extinguishing agent onto the control cabinet 1. The fire extinguishing agent is applied to the surface of the electrical components connected to the inside of the control cabinet 1. When fire extinguishing is not required inside or outside the control cabinet 1, the dustproof net 7 can prevent dust from entering the control cabinet 1 through the exhaust port 14. When the control cabinet 1 catches fire, the extinguishing agent and gas discharged from the second exhaust nozzle 405 will impact the fine dustproof net 7. At this time, the rubber ring 13 deforms, causing the rubber ring 13 to separate from the annular groove 16. This allows the dustproof net 7 and the fixing ring 12 to separate from the exhaust port 14, and the extinguishing agent and gas discharged from the second exhaust nozzle 405 can then be discharged from the exhaust port 14, preventing excessive air pressure inside the control cabinet 1. To mitigate the high risk of fire, the external fire extinguishing mechanism 6 and the internal fire extinguishing mechanism 4 are used to protect both the exterior and interior of the control cabinet 1 from fire. This improves the protective performance of the control cabinet 1 and avoids the problem that some existing fireproof electrical automation control cabinets only provide fire protection by extinguishing the fire inside the cabinet. When other equipment outside the control cabinet catches fire, the external fire source can easily bake the control cabinet, causing damage to the internal components. It should be noted that the fire extinguishing tank 5 is a mature technology that has been published. The fire extinguishing tank 5 is filled with compressed fire extinguishing agent and is not described in detail in the instruction manual.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
