Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet for sheet metal processing equipment that can quickly isolate fire sources. Background Technology

[0002] Panel processing equipment (such as large sawing machines, planers, milling machines, sanders, CNC machining centers, hot presses, etc.) is core equipment in modern wood processing, furniture manufacturing, and building materials production industries. This type of equipment typically has enormous power and complex drives (involving high-power motors, frequency converters, servo systems, etc.), and relies on large, dedicated power distribution cabinets for centralized power supply, control, and protection. The safe and stable operation of these power distribution cabinets is directly related to the continuity of production and the overall safety of the factory.

[0003] The electrical distribution cabinets used in existing sheet metal processing are prone to short circuits, which can lead to high-temperature fires. Since the distribution cabinet cannot be completely filled, there is still a lot of space left, which can easily spread when a fire starts. Therefore, it is necessary to quickly isolate or extinguish the fire source inside the distribution cabinet when a fire breaks out.

[0004] A prior art search revealed a fire-extinguishing and protective distribution cabinet disclosed in patent application number 201911356904.7. This cabinet includes a cabinet body, a main board fixed to a mounting plate, a first connector on the main board, a support plate opposite the mounting plate, a mounting cavity between the support plate and the mounting plate, a sliding mechanism between the support plate and the mounting plate, a sliding seat within the sliding mechanism, a mounting box on the sliding seat, a door opening and closing mechanism at the front of the mounting box, a protective main board inside the mounting box, a second connector on the protective main board, and an airbag and a drive mechanism on the support plate. The airbag stores inert gas and abuts against the rear end of the mounting box. The airbag is connected to a first control valve via a first air supply pipe, and the first control valve is connected to a sand-spraying device fixed to the outer wall of the mounting box, facing the main board. The drive mechanism is connected to the rear end of the mounting box. This design enables fire extinguishing by spraying inert gas from the airbag and sand from the sand-spraying device, improving both the speed and effectiveness of fire suppression.

[0005] Existing distribution cabinets only have a single fire extinguishing structure, resulting in poor fire extinguishing effect after a fire breaks out inside the cabinet. Furthermore, the cabinet usually has ventilation holes, which cannot isolate the inside of the cabinet from the air, thus affecting the fire extinguishing efficiency inside the distribution cabinet. Summary of the Invention

[0006] In view of this, the present invention provides a power distribution cabinet for a board processing equipment that can quickly isolate a fire source. It can extinguish the fire source inside the cabinet by using the extinguishing agent flowing out of the upper and lower chambers, and isolate the air inside and outside the cabinet by using an isolation cover, thereby further improving the fire extinguishing efficiency inside the cabinet.

[0007] This invention provides a power distribution cabinet for a sheet metal processing equipment that can quickly isolate a fire source, specifically including a cabinet body and an isolation cover; The bottom of the cabinet is fixedly connected to a base plate, and the square outer end of the base plate is respectively provided with an inner baffle and an outer baffle. The front side of the outer baffle has a notch. The upper and lower ends of the inner side of the cabinet are separated by partitions to form an upper cavity and a lower cavity, respectively. Pressure gauges and filling tubes are respectively installed on the outer ends of the upper cavity and the lower cavity. A control valve is installed on the filling tube. The upper cavity is filled with dry powder extinguishing agent, and the lower cavity is filled with carbon dioxide extinguishing agent. The isolation cover is fitted onto the outside of the cabinet, and the lower end of the isolation cover is inserted into the inner baffle. Between the frame and the outer baffle, the front side of the isolation cover is hinged with two sets of opposing front sealing doors. The front sealing doors are rotated 90°, and tension springs are respectively hung on the upper and lower ends of the inner side of the two sets of front sealing doors. Steel wire ropes are also hung in the middle of the outer side of the front sealing doors. The steel wire ropes pass around the two sets of support wheels B on the outer side of the isolation cover in sequence, and pass through the perforation B of the isolation cover and connect to the perforation A of the cabinet body to the sealing baffle. A nylon rope C is tied between the other side of the sealing baffle and the hanging ring opposite to the cabinet body.

[0008] Optionally, the partition plate of the upper cavity is provided with two sets of through holes, and rubber columns are respectively sealed and fitted in the through holes. Plastic tubes are movably inserted in the middle of the rubber columns. The upper end of the plastic tubes is inserted into the upper cavity and fitted with a spring, which is fixedly connected to the top plate, and the spring is in a tensioned state.

[0009] Optionally, the plastic tube extends downward through the bottom end of the partition in the upper cavity and is provided with a powder inlet hole. The lower end of the plastic tube is also provided with a lower baffle and is connected to an L-shaped powder outlet pipe. The powder inlet hole and the L-shaped powder outlet pipe are respectively located on the upper and lower sides of the lower baffle.

[0010] Optionally, the bottom end of the plastic tube is also screwed with a bottom cap, and a vertical nylon pull rope A is tied between the bottom cap and the hanging ring on the top side of the partition in the lower cavity.

[0011] Optionally, the partition of the lower cavity is provided with an air vent, and the bottom of the air vent is plugged with a rubber stopper. The bottom of the rubber stopper is fixedly connected to a counterweight, and the top of the rubber stopper is connected to a nylon pull rope B. The nylon pull rope B passes around the two sets of support wheels A on the top side of the partition of the lower cavity in sequence and is connected to the hanging ring on the top side of the partition of the lower cavity.

[0012] Optionally, a rubber ring is attached to the side of the sealing baffle that is connected to the steel wire rope. The outer diameter of the sealing baffle is smaller than the inner diameter of the perforation A, and the outer diameter of the sealing baffle is larger than the inner diameter of the perforation B.

[0013] Optionally, when the two sets of front sealing door seals are affixed to the front opening side of the isolation cover, the tension spring remains in a tensioned state, and the rubber ring of the sealing baffle is affixed to the inside of the perforation B.

[0014] This invention provides a power distribution cabinet for sheet metal processing equipment that can quickly isolate fire sources, and has the following beneficial effects: 1. This invention can extinguish fire sources inside the cabinet by using extinguishing agents flowing out from the upper and lower chambers, and further improve the fire extinguishing efficiency inside the cabinet by isolating the air inside and outside through the isolation cover.

[0015] 2. By filling the upper cavity with dry powder extinguishing agent, after the fire inside the distribution cabinet is broken, the vertical nylon pull rope A is burned off, and the spring drives the lower end of the plastic tube to enter the upper cavity. The dry powder extinguishing agent inside the upper cavity enters the plastic tube through the powder inlet hole under pressure and flows out through the L-shaped powder outlet pipe, thus extinguishing the fire inside the cabinet.

[0016] 3. By filling the lower cavity with carbon dioxide extinguishing agent, after the fire inside the distribution cabinet is ignited, the nylon pull rope B is burned off, and the counterweight moves the rubber stopper downward away from the vent hole, so that the carbon dioxide extinguishing agent in the lower cavity flows out from the vent hole, thus extinguishing the fire inside the cabinet.

[0017] 4. By fastening an isolation cover to the outside of the cabinet, after a fire breaks out inside the distribution cabinet, the two sets of nylon pull ropes C are burned off. Under the action of the tension spring, the two sets of front sealing doors are closed. At the same time, the steel wire pull rope and the sealing baffle are pulled. The rubber ring of the sealing baffle is attached to the inside of the perforation B on the isolation cover, sealing the perforation B and isolating the air inside the isolation cover from the outside air, thereby further improving the fire extinguishing efficiency inside the cabinet.

[0022] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0023] Example: Please refer to Figures 1 to 14 : Example 1: The present invention proposes a power distribution cabinet for a board processing equipment that can quickly isolate fire sources, including a cabinet body 1 and an isolation cover 2; A base plate 101 is fixedly connected to the bottom of cabinet 1. The square outer end of the base plate 101 is provided with an inner baffle 1011 and an outer baffle 1012. The front side of the outer baffle 1012 is provided with a notch. The upper and lower ends of the inner side of cabinet 1 are separated by partitions to form an upper cavity 102 and a lower cavity 103. Pressure gauges and filling tubes are respectively installed on the outer ends of the upper cavity 102 and the lower cavity 103. A control valve is installed on the filling tube. The upper cavity 102 is filled with dry powder extinguishing agent, and the lower cavity 103 is filled with carbon dioxide extinguishing agent. An isolation cover 2 is fitted onto the outside of cabinet 1, and the lower end of the isolation cover 2 is inserted into the inner baffle 1011 and the outer baffle 1012. Between the baffle frames 1012, two sets of opposing front sealing doors 201 are hinged to the front side of the isolation cover 2. The front sealing doors 201 are rotated 90°, and tension springs 202 are respectively hung on the upper and lower ends of the inner side of the two sets of front sealing doors 201. Steel wire ropes 203 are also hung in the middle of the outer side of the front sealing doors 201. The steel wire ropes 203 pass around the two sets of support wheels B204 on the outer side of the isolation cover 2 in sequence, and pass through the perforation B205 of the isolation cover 2 and connect to the perforation A104 of the cabinet 1 to the sealing baffle 206. A nylon rope C207 is tied between the other side of the sealing baffle 206 and the hanging ring opposite to the cabinet 1.

[0024] Among them, such as Figure 9 and Figure 10 , Figure 12 and Figure 13 As shown, the partition plate of the upper cavity 102 has two sets of through holes, and rubber pillars 1021 are respectively sealed and clamped in the through holes. Plastic tubes 1022 are movably inserted through the middle of the rubber pillars 1021. The upper end of the plastic tube 1022 is inserted into the upper cavity 102 and fitted with a spring 1023, which is fixedly connected to the top plate 10221. The spring 1023 is in a tensioned state. The plastic tube 1022 extends downward out of the partition plate of the upper cavity 102 and has a powder inlet hole 10222 at the bottom. The lower end of the plastic tube 1022 also has a lower baffle 10223, and L-shaped powder outlet pipes 10224 are inserted and connected to it. The powder inlet hole 10222 and the L-shaped powder outlet pipe are connected to each other. Powder pipes 10224 are respectively installed on the upper and lower sides of the lower baffle 10223. The bottom end of the plastic pipe 1022 is also screwed with a bottom cap 1024. A vertical nylon pull rope A1025 is tied between the bottom cap 1024 and the hanging ring on the top side of the partition of the lower cavity 103. After the fire inside the cabinet 1, the vertical nylon pull rope A1025 is burned off, and the spring 1023 drives the lower end of the plastic pipe 1022 to pass into the upper cavity 102. The dry powder extinguishing agent inside the upper cavity 102 enters the plastic pipe 1022 through the powder inlet hole 10222 under pressure and flows out through the L-shaped powder outlet pipe 10224, which can extinguish the fire inside the cabinet 1.

[0025] Among them, such as Figure 9 and Figure 11 , Figure 12 and Figure 14 As shown, the partition of the lower cavity 103 is provided with an air vent 1031, and the bottom of the air vent 1031 is plugged with a rubber stopper 1032. The bottom of the rubber stopper 1032 is fixedly connected to a counterweight 1033, and the top of the rubber stopper 1032 is connected to a nylon pull rope B1034. The nylon pull rope B1034 passes around the two sets of support wheels A1035 on the top side of the partition of the lower cavity 103 in sequence, and is connected to the hanging ring on the top side of the partition of the lower cavity 103. After the fire inside the cabinet 1, the nylon pull rope B1034 can be burned through, and the counterweight 1033 drives the rubber stopper 1032 downward away from the air vent 1031, so that the carbon dioxide extinguishing agent in the lower cavity 103 flows out from the air vent 1031, extinguishing the fire inside the cabinet 1.

[0026] Example 2, based on Example 1, such as Figures 1-7 As shown, a rubber ring is attached to the side of the sealing baffle 206 connected to the steel wire rope 203. The outer diameter of the sealing baffle 206 is smaller than the inner diameter of the perforation A104, and the outer diameter of the sealing baffle 206 is larger than the inner diameter of the perforation B205. When the two sets of front sealing doors 201 are sealed against the front opening side of the isolation cover 2, the tension spring 202 is still in a tensile state, and the rubber ring of the sealing baffle 206 is sealed against the inside of the perforation B205. After the fire inside the cabinet 1, the two sets of nylon ropes C207 are burned off. Under the action of the tension spring 202, the two sets of front sealing doors 201 are closed. At the same time, the steel wire rope 203 and the sealing baffle 206 are pulled. The rubber ring of the sealing baffle 206 is attached to the inside of the perforation B205 on the isolation cover 2, sealing the perforation B205 and isolating the air inside the isolation cover 2 from the outside air, thereby further improving the fire extinguishing efficiency inside the cabinet 1.

[0027] The specific usage and function of this embodiment are as follows: In this invention, firstly, the powder inlet hole 10222 of the plastic tube 1022 is pulled out from the bottom end of the partition of the upper cavity 102, and the vertical nylon pull rope A1025 is tightened and tied between the bottom cap 1024 and the hanging ring on the top side of the partition of the lower cavity 103. Then, dry powder extinguishing agent is filled through the filling tube on the outside of the upper cavity 102, and the pressure inside the upper cavity 102 is controlled by the pressure gauge. Then, the top end of the rubber stopper 1032 is pulled to the bottom end of the air outlet 1031 inside the lower cavity 103, and the rubber stopper 1032 is pulled by the nylon pull rope B1034. The other end of the nylon pull rope B1034 is then wrapped around the support wheel A103. 5. And tighten the connection with the hanging ring on the top side of the partition of the lower cavity 103. Then fill the carbon dioxide extinguishing agent through the filling tube on the outside of the lower cavity 103 and control the pressure inside the lower cavity 103 through the pressure gauge. Then fasten the isolation cover 2 on the outside of the cabinet 1 and insert the lower end of the isolation cover 2 between the inner baffle 1011 and the outer baffle 1012. Turn the two sets of front sealing doors 201 open by 90°. Then open the sealing door of the cabinet 1. Pass the steel wire rope 203 and the corresponding sealing baffle 206 through the through hole A104 of the cabinet 1 respectively. Tighten the connection between the other side of the sealing baffle 206 and the hanging ring opposite to the cabinet 1 through the nylon rope C207. After a fire breaks out inside cabinet 1, the vertical nylon pull rope A1025, nylon pull rope B1034, and two sets of nylon pull ropes C207 will burn through. Spring 1023 will cause the lower end of plastic tube 1022 to penetrate into upper cavity 102. Under pressure, the dry powder extinguishing agent inside upper cavity 102 will enter plastic tube 1022 through powder inlet 10222 and flow out through L-shaped powder outlet 10224. Simultaneously, counterweight 1033 will cause rubber stopper 1032 to move downwards away from vent 1031, causing the lower cavity... The carbon dioxide extinguishing agent in 103 flows out from the vent 1031, extinguishing the fire inside the cabinet 1. Under the action of the tension spring 202, the two sets of front sealing doors 201 are closed. At the same time, the steel wire rope 203 and the sealing baffle 206 are pulled. The rubber ring of the sealing baffle 206 is attached to the inside of the perforation B205 on the isolation cover 2, sealing the perforation B205 and isolating the air inside the isolation cover 2 from the outside air, further improving the fire extinguishing efficiency inside the cabinet 1.
