Description
Technical Field
[0001] The invention belongs to the technical field of electrical cabinets, and particularly relates to an explosion-proof electrical cabinet with a real-time monitoring function and an operation method thereof. Background Art
[0002] An explosion-proof electrical cabinet assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements to form a low-voltage power distribution device. It is mainly used in chemical plants, petrochemical industries, offshore drilling platforms and other environments where flammable and explosive substances exist to prevent explosion accidents caused by electric sparks or high temperatures generated during the operation of electrical equipment. Various electronic components are often installed in the explosion-proof electrical cabinet for cooperation.
[0003] Conventional explosion-proof electrical cabinets mainly rely on the external shell to achieve the explosion-proof function. However, once a fire is caused by smoke inside the electrical cabinet, it cannot be effectively monitored. The gas generated by the burning of internal electronic components contains poisonous gas, and this part of the poisonous gas will overflow from the gaps in the electrical cabinet, resulting in risks in the surrounding environment.
[0004] At the same time, conventional explosion-proof electrical cabinets only prevent the electrical cabinet from exploding, but when combustion occurs inside the electrical cabinet, it cannot be flame-retarded in the first time and cannot give an alarm, which is likely to cause all the internal electronic components to be burned out, and there is an urgent need for improvement. Summary of the Invention

The air inlet valve and the exhaust valve are one-way valves, and the directions of the valves are respectively inward conduction and outward cut-off, and outward conduction and inward cut-off. Inside the collection tank, a sealing plug is movably sleeved. The bottom end of the sealing plug is fixedly connected with an extension rod located inside the collection tank. The bottom end of the extension rod penetrates through the bottom end of the collection tank and is connected to the top of the control assembly. When the top of the sealing plug contacts the top of the inner cavity of the collection tank, that is, when the sealing plug is at the highest point, the bottom end of the sealing plug is located directly above the air inlet valve and the exhaust valve.
[0007] During normal use, it is necessary to ensure that there is no poisonous gas stored inside the gas collection assembly.

[0009] As a further technical solution of the present invention, a laser emitter is fixedly installed at the top end of the inner cavity of the detection box, a laser receiver is fixedly installed at the bottom end of the inner cavity of the detection box, the middle parts of the laser emitter and the laser receiver are on the same central axis, and arc-shaped baffles are symmetrically installed on the front and rear sides of the inner cavity of the detection box in a diffused shape.
[0010] In the normal state, the laser emitter and the laser receiver are in the normally open state. At this time, there is no smoke inside the detection box, and the laser emitted by the laser emitter can be normally received by the laser receiver.
[0011] When smoke appears inside the cabinet, at this time, the smoke can be gathered through the collection cavity, enter the inside of the three-way valve, and enter the inside of the detection box after being gathered by the three-way valve. At this time, the smoke can be blocked by the arc-shaped baffle, so that the smoke is gathered between the laser emitter and the laser receiver. At this time, the laser transmission channel is blocked, and the laser receiver cannot normally receive the light beam from the laser emitter, and a signal can be conducted to the electromagnet.

[0013] As a further technical solution of the present invention, the top end of the extension column penetrates through the top end of the limiting plate and is fixedly connected to an electromagnet. A limiting spring is movably sleeved on the outer side surface of the fixed rod, and the upper and lower ends of the limiting spring are respectively connected to the bottom end of the limiting plate and the top end of the movable sleeve. The top end of the electromagnet is connected to the bottom end of the extension rod.
[0014] As a further technical solution of the present invention, a linkage frame is fixedly installed at the rear end of the electromagnet, and the bottom end of the linkage frame is connected to the gas collection component. When the top end of the electromagnet adsorbs to the bottom end of the collection tank, the sealing plug is at the highest point position, and the limiting spring is in the extreme compression state. The output ends of the laser emitter and the laser receiver are electrically connected to the input end of the electromagnet.
[0015] When the power supply of the electromagnet is turned on, at this time, the electromagnet generates magnetic force and adsorbs to the top end of the collection tank until it reaches the highest point. When the electromagnet rises, at this time, the movable sleeve and the extension column rise accordingly, and at the same time, the limiting spring can be compressed until the electromagnet rises to the highest point, and at this time, the linkage frame rises to the highest point.
[0016] As a further technical solution of the present invention, the gas collection assembly includes a locking seat, the locking seat is connected to the rear end of the cabinet body, a collection tank is fixedly sleeved inside the locking seat, a bent pipe is fixedly communicated with the top end of the collection tank, the gas collection assembly further includes a gas guide box, the gas guide box is fixedly communicated with the rear end of the gas guide groove, a gas guide port is fixedly communicated at a position near the lower part of the rear end of the gas guide box, a bent pipe is fixedly communicated with the rear end of the gas guide port, and the bottom end of the bent pipe is communicated with the top end of the collection tank.
[0017] When the electromagnet moves upward, the baffle can be pulled upward at this time, and the channel of the gas guide port is opened. At this time, the poisonous gas inside the cabinet body can be exported through the gas guide port and through the bent pipe, and finally enter the inside of the collection tank for temporary storage, completing the storage process of the poisonous gas. When the poisonous gas is emptied, there is no poisonous gas inside the detection assembly at this time, and the control assembly automatically resets accordingly, driving the baffle to automatically descend and reset, cutting off the output channel of the poisonous gas, and completing the self-storage process of the poisonous gas.
[0018] By using the smoke generated by combustion to block the light transmission channel, the self-judgment process is completed, and the channel of the gas guide port is automatically opened through self-judgment, realizing the automatic evacuation and storage of poisonous gas. The whole process is automatically completed, and the poisonous gas can be processed automatically at the initial stage of combustion, avoiding the problem of poisonous gas leakage of traditional devices and improving the safety of the device.
[0019] As a further technical solution of the present invention, the self-extinguishing assembly includes a fire extinguishing pipe, the bottom end of the fire extinguishing pipe is fixedly communicated with a power tank, the bottom end of the power tank is fixedly communicated with an air injection hole, the end of the fire extinguishing pipe far away from the power tank is communicated with an exhaust valve, a main shaft is movably connected to the middle of the power tank, and an impeller located inside the power tank is fixedly sleeved on the outer side of the main shaft.
[0020] As a further technical solution of the present invention, swing rods are fixedly installed at both the left and right ends of the impeller, a clamping groove is movably clamped in the middle of the swing rod, and movable blocks are movably clamped inside the clamping grooves.
[0021] When the electromagnet moves upward, the extension rod can be driven to move upward synchronously. At this time, the sealing plug moves upward accordingly. When the sealing plug moves upward to the highest point, the channels of the air inlet valve and the exhaust valve are both opened at this time. The fire extinguishing agent inside the perfluorocyclohexanone storage tank enters the inside of the collection tank through the fire extinguishing agent pipe and the air inlet valve, and finally is exported through the exhaust valve, and enters the inside of the cabinet body through the fire extinguishing pipe, the power tank and the air injection hole, completing the self-extinguishing process.
[0022] By using the smoke generated during the combustion inside the cabinet body in cooperation with the detection component for judgment, and realizing the active discharge of the smoke through the cooperation between the control component and the gas collection component. At the same time, when the smoke is actively discharged, the automatic injection of the fire extinguishing agent can be synchronously realized. The whole process is automatically completed, that is, when smoke occurs, the smoke is actively discharged, and at the same time, active fire extinguishing is carried out, effectively reducing the damage to the components inside the cabinet body and further improving safety.
[0023] At the same time, when the fire extinguishing agent enters the power tank, it can push the impeller to rotate at this time. At this time, the main shaft rotates accordingly and drives the swing rod on the outer side to rotate circumferentially. When the swing rod rotates, it can synchronously drive the movable block to displace relative to the card slot. At this time, the movable block collides with the card slot, making a sound and realizing the alarm process.
[0024] By using the process of the device automatically collecting poisonous gas and automatically extinguishing the fire, through the export of the fire extinguishing agent, the active rotation of the main shaft is realized, and finally the circumferential rotation of the swing rod is realized. Finally, the displacement of the movable block is realized, realizing mechanical sound and vibration, and completing the automatic alarm process. The whole process is completed simultaneously with the automatic fire extinguishing, effectively reducing the loss during a fire.
[0025] An operation method of an explosion-proof electrical cabinet with real-time monitoring function includes the following steps:
[0026] S1: When smoke appears inside the cabinet body, the smoke can be collected through the collection chamber, and at the same time, it enters the inside of the three-way valve and then enters the inside of the detection box through the three-way valve. After being blocked by the arc-shaped baffle, it enters between the laser emitter and the laser receiver. At this time, the emitted laser is blocked, and the power supply of the electromagnet is turned on;
[0027] S2: After the power supply of the electromagnet is turned on, the electromagnet rises at this time until it adsorbs to the bottom end of the collection tank. At this time, the extension rod and the sealing plug rise accordingly, and at the same time, the linkage frame is driven to rise. When the extension column rises, the baffle can be synchronously driven to rise. At this time, the channel of the air guide port is opened, and the poisonous gas is exported through the elbow pipe and enters the inside of the collection tank for temporary storage;
[0028] S3: At the same time, the rising of the electromagnet can push the sealing plug to rise to the highest point. The fire extinguishing agent inside the perfluorinated hexanone storage tank enters the inside of the collection tank through the fire extinguishing agent pipe and the intake valve, and finally is exported through the self-extinguishing component. At this time, the fire extinguishing agent is imported into the inside of the cabinet body through the fire extinguishing pipe, the power tank and the air injection hole for fire extinguishing operations;
[0029] S4: The fire extinguishing agent imported into the power tank can push the impeller to rotate. At this time, the swing rod rotates circumferentially, and drives the movable block to displace relative to the card slot, so that the movable block collides with the side of the card slot, generating vibration and sound, and completing the alarm process.
[0030] The beneficial effects of the present invention are as follows:
[0031] (1) By using the smoke generated by combustion to block the light transmission channel, the self-judgment process is completed, and the channel of the air guide port is automatically opened through self-judgment, realizing the automatic evacuation and storage of poisonous gas. The whole process is automatically completed, and the poisonous gas can be processed automatically at the initial stage of combustion, avoiding the problem of poisonous gas leakage of traditional devices and improving the safety of the device.
[0032] (2) By using the smoke generated during the combustion inside the cabinet body in cooperation with the detection component for judgment, and using the cooperation between the control component and the gas collection component to actively discharge the smoke. At the same time, when the smoke is actively discharged, the automatic injection of the fire extinguishing agent can be synchronized. The whole process is automatically completed, that is, when smoke occurs, the smoke is actively discharged and active fire extinguishing is carried out at the same time, effectively reducing the damage to the components inside the cabinet body and further improving the safety.
[0033] (3) By using the process of automatically collecting poisonous gas and automatically extinguishing fire in the device, through the export of the fire extinguishing agent, the active rotation of the main shaft is realized, and finally the circumferential rotation of the swing rod is realized, and finally the displacement of the movable block is realized, realizing mechanical sound vibration and completing the automatic alarm process. The whole process is completed simultaneously with the automatic fire extinguishing, effectively reducing the loss during a fire. Description of the Drawings

The other ends of the fire extinguishing agent pipes 16 are connected to the air inlet valves 9. The air inlet valves 9 and the exhaust valve 10 are one-way valves, and the directions of the valves are respectively inward conduction and outward cut-off, and outward conduction and inward cut-off. A sealing plug 14 is movably sleeved inside the collection tank 8. The bottom end of the sealing plug 14 is fixedly connected to an extension rod 15 located inside the collection tank 8. The bottom end of the extension rod 15 penetrates through the bottom end of the collection tank 8 and is connected to the top of the control assembly 7. When the top of the sealing plug 14 contacts the top of the inner cavity of the collection tank 8, that is, when the sealing plug 14 is at the highest point, the bottom end of the sealing plug 14 is located directly above the air inlet valves 9 and the exhaust valve 10.
[0047] During normal use, it is necessary to ensure that there is no poisonous gas stored inside the gas collection assembly 5. At the same time, it is necessary to ensure that perfluoromethylcyclohexane is stored inside the perfluoromethylcyclohexane storage tanks 12. The control assembly 7 and the gas collection assembly 5 are restored to the initial state, and the power supply of the detection assembly 6 is turned on to complete the preparations before monitoring.
[0048] Such as Figure 2 and Figure 3 and Figure 6As shown in the figure, the detection component 6 includes that the top end of the three-way valve 601 is connected to the top end of the inner cavity of the cabinet body 1. The detection component 6 further includes a detection box 602. The left and right ends of the three-way valve 601 penetrate through the top end of the cabinet body 1 and are communicated with the left and right ends of the detection box 602. The bottom end of the three-way valve 601 is fixedly communicated with a collection cavity 606 located inside the cabinet body 1. A laser emitter 603 is fixedly installed at the top end of the inner cavity of the detection box 602, and a laser receiver 604 is fixedly installed at the bottom end of the inner cavity of the detection box 602. The middle parts of the laser emitter 603 and the laser receiver 604 are on the same central axis. The front and back sides of the inner cavity of the detection box 602 are in a diffused shape and symmetrically installed with arc-shaped baffles 605.
[0049] In the normal state, the laser emitter 603 and the laser receiver 604 are in the normally open state. At this time, there is no smoke inside the detection box 602, and the laser emitted by the laser emitter 603 can be normally received by the laser receiver 604.
[0050] When there is smoke inside the cabinet body 1, at this time, the smoke can be gathered through the collection cavity 606, then enter the inside of the three-way valve 601, and after being gathered by the three-way valve 601, enter the inside of the detection box 602. At this time, the smoke can be blocked by the arc-shaped baffle 605, so that the smoke is gathered between the laser emitter 603 and the laser receiver 604. At this time, the laser transmission channel is blocked, and the laser receiver 604 cannot normally receive the light beam from the laser emitter 603, and a signal can be conducted to the electromagnet 704.
[0051] As Figure 2 and Figure 3 and Figure 8 As shown in the figure, the manipulation component 7 includes a fixed rod 701. The bottom end of the fixed rod 701 is fixedly connected to the top end of the three-way valve 601. An activity sleeve 703 is movably sleeved inside the fixed rod 701. The top end of the activity sleeve 703 is fixedly connected with extension columns 705 at equal angles. The top end of the fixed rod 701 is fixedly connected with a limit plate 702. The top ends of the extension columns 705 penetrate through the top end of the limit plate 702 and are fixedly connected with an electromagnet 704. The outer side surface of the fixed rod 701 is movably sleeved with a limit spring 707. The upper and lower ends of the limit spring 707 are respectively connected to the bottom end of the limit plate 702 and the top end of the activity sleeve 703. The top end of the electromagnet 704 is connected to the bottom end of the extension rod 15. A linkage frame 706 is fixedly installed at the rear end of the electromagnet 704. The bottom end of the linkage frame 706 is connected to the gas collection component 5. When the top end of the electromagnet 704 is adsorbed to the bottom end of the collection tank 8, the sealing plug 14 is at the highest point position, and the limit spring 707 is in the extreme compression state. The output ends of the laser emitter 603 and the laser receiver 604 are electrically connected to the input end of the electromagnet 704.
[0052] When the power supply of the electromagnet 704 is turned on, the electromagnet 704 generates magnetic force accordingly and adsorbs to the top of the collection tank 8 until the electromagnet 704 rises. At this time, the movable sleeve 703 and the extension column 705 rise accordingly, and the limit spring 707 can be compressed until the electromagnet 704 rises to the highest point. At this time, the linkage frame 706 rises to the highest point accordingly.
[0053] As Figure 2 and Figure 5 shown, the gas collection assembly 5 includes a locking seat 501. The locking seat 501 is connected to the rear end of the cabinet body 1. A collection tank 502 is fixedly sleeved inside the locking seat 501. A bent pipe 503 is fixedly communicated with the top end of the collection tank 502. The gas collection assembly 5 further includes a gas guide box 504. The gas guide box 504 is fixedly communicated with the rear end of the gas guide groove 4. A gas guide port 505 is fixedly communicated at a position near the lower part of the rear end of the gas guide box 504. The rear end of the gas guide port 505 is fixedly communicated with the bent pipe 503. The bottom end of the bent pipe 503 is communicated with the top end of the collection tank 502.
[0054] Embodiment: When the electromagnet 704 moves upward, the baffle 506 can be pulled upward at this time, and the channel of the gas guide port 505 is opened. At this time, the poisonous gas inside the cabinet body 1 can be exported through the gas guide port 505 and through the bent pipe 503, and finally enter the inside of the collection tank 502 for temporary storage, completing the storage process of the poisonous gas. When the poisonous gas is emptied, there is no poisonous gas inside the detection assembly 6 at this time. The control assembly 7 automatically resets accordingly and drives the baffle 506 to automatically descend and reset, cutting off the output channel of the poisonous gas and completing the self-storage process of the poisonous gas.
[0055] By using the smoke generated by combustion to block the light transmission channel, the self-judgment process is completed, and the channel of the gas guide port 505 is automatically opened through self-judgment, realizing the automatic evacuation and storage of poisonous gas. The whole process is automatically completed, and the poisonous gas can be processed automatically at the initial stage of combustion, avoiding the problem of poisonous gas leakage of traditional devices and improving the safety of the device.
[0056] As Figure 2 and Figure 3 and Figure 10 shown, the self-extinguishing assembly 11 includes a fire extinguishing pipe 111. The bottom end of the fire extinguishing pipe 111 is fixedly communicated with a power tank 112. The bottom end of the power tank 112 is fixedly communicated with the air injection hole 3. One end of the fire extinguishing pipe 111 far from the power tank 112 is communicated with the exhaust valve 10. A main shaft 114 is movably connected to the middle of the power tank 112. An impeller 113 located inside the power tank 112 is fixedly sleeved on the outer side of the main shaft 114. Swing rods 115 are fixedly installed at both the left and right ends of the impeller 113. A clamping groove 116 is movably clamped in the middle of the swing rod 115. Movable blocks 117 are movably clamped in the clamping grooves 116.
[0057] Embodiment: When the electromagnet 704 moves upward, the extension rod 15 can be driven to move upward synchronously. At this time, the sealing plug 14 moves upward accordingly. When the sealing plug 14 moves upward to the highest point, the channels of the intake valve 9 and the exhaust valve 10 are both opened. The fire extinguishing agent located inside the perfluorocyclohexanone storage tank 12 then enters the inside of the collection tank 8 through the fire extinguishing agent pipe 16 and the intake valve 9, and is finally discharged through the exhaust valve 10, and enters the inside of the cabinet body 1 through the fire extinguishing pipe 111, the power tank 112, and the air injection hole 3, completing the process of autonomous fire extinguishing.
[0058] By using the smoke generated during the combustion inside the cabinet body 1 in cooperation with the detection component 6 for judgment, and using the cooperation between the manipulation component 7 and the gas collection component 5 to achieve the active discharge of the smoke. At the same time, when the smoke is actively discharged, the automatic injection of the fire extinguishing agent can be synchronously achieved. The whole process is automatically completed, that is, when smoke occurs, the smoke is actively discharged, and at the same time, active fire extinguishing is carried out, effectively reducing the damage to the components inside the cabinet body 1 and further improving safety.
[0059] At the same time, when the fire extinguishing agent enters the power tank 112, it can then push the impeller 113 to rotate. At this time, the main shaft 114 rotates accordingly and drives the swing rod 115 on the outer side to rotate circumferentially. When the swing rod 115 rotates, it can synchronously drive the movable block 117 to displace relative to the card slot 116. At this time, the movable block 117 collides with the card slot 116, making a sound and realizing the alarm process.
[0060] By using the process of the device automatically collecting poisonous gas and automatically extinguishing fire, through the export of the fire extinguishing agent, the active rotation of the main shaft 114 is realized, and finally the circumferential rotation of the swing rod 115 is realized. Finally, the displacement of the movable block 117 is realized, realizing mechanical sound and vibration, and completing the automatic alarm process. The whole process is completed simultaneously with the automatic fire extinguishing, effectively reducing the losses during a fire.
[0061] An operation method of an explosion-proof electrical cabinet with real-time monitoring function includes the following steps:
[0062] S1: When smoke appears inside the cabinet body 1, the smoke can be collected through the collection chamber 606, and at the same time enters the inside of the three-way valve 601, and enters the inside of the detection box 602 through the three-way valve 601. After being blocked by the arc-shaped baffle 605, it enters between the laser emitter 603 and the laser receiver 604. At this time, the emitted laser is blocked, and the power supply of the electromagnet 704 is turned on;
[0063] S2: After the power supply of the electromagnet 704 is turned on, the electromagnet 704 then rises until it adsorbs to the bottom end of the collection tank 8. At this time, the extension rod 15 and the sealing plug 14 also rise accordingly, and at the same time drive the linkage frame 706 to rise. When the extension column 705 rises, it can synchronously drive the baffle 506 to rise. At this time, the passage of the air guide port 505 is opened, and the poisonous gas then is led out through the elbow pipe 503 and enters the interior of the collection tank 502 for temporary storage;
[0064] S3: At the same time, the rising of the electromagnet 704 can push the sealing plug 14 to rise to the highest point. The fire extinguishing agent in the perfluoroketone storage tank 12 then passes through the fire extinguishing agent pipe 16 and the intake valve 9 and enters the interior of the collection tank 8, and finally is led out through the self - extinguishing component 11. At this time, the fire extinguishing agent then passes through the fire extinguishing pipe 111, the power tank 112, and the air injection hole 3 and is introduced into the interior of the cabinet body 1 for fire extinguishing operations;
[0065] S4: The fire extinguishing agent introduced into the power tank 112 can push the impeller 113 to rotate. At this time, the swing rod 115 rotates circumferentially accordingly, and drives the movable block 117 to displace relative to the card slot 116, so that the movable block 117 collides with the side of the card slot 116, generating vibrations and sounds to complete the alarm process.
[0066] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
