Description

Technical Field

[0001] The present application relates to the technical field of magnetically controlled reactors, and in particular to a fire extinguishing device of a magnetically controlled reactor and a magnetically controlled reactor. Background Art

[0002] Magnetically controlled reactors (magnetically controlled reactors) are known as magnetic valve controllable reactors, or MCR for short. They are shunt reactors with adjustable capacity, mainly used for reactive power compensation in power systems.

[0003] The reactor has many internal electrical components, which will dissipate a large amount of heat. Therefore, a fan is provided to dissipate the heat of the reactor. However, during operation, due to factors such as overload or short circuit, the reactor may be at risk of fire. In particular, after a fire occurs, the operation of the fan further increases the risk of the fire spreading, thereby reducing the safety of the reactor. Summary of the invention

[0004] In order to improve the safety of the reactor, the present application provides a fire extinguishing device for a magnetically controlled reactor and a magnetically controlled reactor.

[0005] In the first aspect, the fire extinguishing device of the magnetically controlled reactor provided in the present application adopts the following technical solution: The fire extinguishing device of the magnetically controlled reactor comprises an air inlet pipe, an air outlet pipe and a fire detection component which are arranged on a box body, wherein the air inlet pipe is used to introduce air into the box body, the air outlet pipe is used to install a fan to realize air outlet, the fire detection component is used to detect whether a fire occurs in the box body and to sound an alarm after the fire occurs, and further comprises a blocking mechanism 1 and a blocking mechanism 2 which are respectively arranged on the air inlet pipe and the air outlet pipe; when the fire detection component detects a fire, the blocking mechanism 1 blocks the air inlet pipe and the fan continues to run and is used to extract the air in the box body, and then the fan stops and the blocking mechanism 2 starts to block the air outlet pipe.

[0006] By adopting the above technical solution, the fan is started, the outside air enters the box through the air inlet pipe, and the heat in the air and the box is output through the air outlet pipe, thereby realizing the heat dissipation of the electrical components in the box.

[0007] When the fire detection component detects a fire in the box, the fire detection component starts to alarm, and at the same time, the blocking mechanism 1 first blocks the air inlet duct to prevent air from entering the box. At the same time, the fan continues to start, so that the air in the box is output through the air outlet duct, thereby extracting the air in the box. Then the fan is turned off and the sealing mechanism 2 blocks the air outlet duct, so that the outside air cannot enter the box, and the fire point in the box is extinguished due to lack of oxygen, thereby greatly improving the safety of the reactor.

[0008] The fire detection component alarm reminds the staff to pay attention to the fire in the box. After the fire risk is eliminated, the blocking mechanism 1 and the blocking mechanism 2 open the air inlet and outlet ducts, and the fan starts to continue to dissipate heat for the box.

[0009] The air in the box is sucked by the fan, which greatly speeds up the air output in the box, so that the fire point can be extinguished more quickly, further improving the safety of the reactor; and compared with extinguishing the fire by spraying fire extinguishing materials, the above method greatly reduces the probability of fire extinguishing materials causing damage to unburned electrical components, and is also convenient for finding the fire point, thereby facilitating subsequent maintenance and improvement of the equipment, further improving the safety of the reactor.

[0010] Optionally, the second blocking mechanism includes: A blocking plate, movably arranged on the air outlet pipe; The driving component is used to drive the blocking plate to move and to open or block the air outlet duct.

[0011] By adopting the above technical solution, the driving component drives the blocking plate to move, thereby realizing that the blocking plate opens or blocks the air outlet duct.

[0012] Optionally, the driving component includes: The rotating block is rotatably arranged on the top wall of the air outlet pipe through the rotating shaft, and the blocking plate is slidably arranged on the rotating block and the sliding direction is perpendicular to the axis of the rotating shaft; A rotating column is rotatably arranged on the inner wall of the air outlet pipe; A rotating rod, one end of which is arranged on the rotating column and the other end of which is rotatably connected to the blocking plate; The driving member is used to drive the rotating column to rotate, so that the blocking plate is horizontally placed on the upper surface of the air outlet pipe for positioning when opening the air outlet pipe, or the blocking plate is vertically placed against the air outlet pipe for blocking.

[0013] By adopting the above technical solution, the driving member drives the rotating column to rotate, the rotating column rotates to drive the rotating rod to rotate around the axis of the rotating column, the rotating rod rotates to drive the blocking plate to move on the rotating block, and the movement of the blocking plate simultaneously pushes the rotating block to rotate, so that the blocking plate is horizontally placed on the top of the air outlet pipe, or the blocking plate is vertically placed and pressed against the air outlet pipe to block it, thereby achieving opening or blocking of the air outlet pipe.

[0014] At the same time, when the blocking plate is placed on the top of the air outlet duct, most of the gravity of the blocking plate will be concentrated on the air outlet duct and the other part will be concentrated on the rotating block, so that the blocking plate exerts extremely small force on the rotating rod and the driving member, reducing the probability of damage to the rotating plate and the driving member, thereby improving the stability of the rotating rod and the driving member during operation, and the blocking plate is also pressed against the air outlet duct in a vertical state, so the gravity of the blocking plate will be decomposed into a pulling force on the rotating rod and a pressure on the air outlet duct. Furthermore, the blocking time of the blocking plate on the air outlet duct is relatively short, and the fire detection component will sound an alarm. The staff will place the blocking plate horizontally in time after eliminating the fire risk. Therefore, compared with the ordinary vertical sliding structure, it can greatly improve the stability during operation, improve the fire extinguishing effect on the fire point in the box, and improve the safety of the reactor.

[0015] Optionally, an elastic component is provided on the rotating rod, and the elastic component includes: The first positioning block and the second positioning block are rotatably arranged on the rotating rod and the inner wall of the air outlet pipe respectively; Two guide rods are respectively arranged on the side walls of the first positioning block and the second positioning block on the opposite side; The spring has two ends pressed against the side walls on the opposite side of the positioning block one and the positioning block two and is respectively mounted on the two guide rods for positioning and in a compressed state. When the blocking plate is rotated and placed horizontally on the upper surface of the air outlet duct, the spring keeps the blocking plate from moving closer to the box body. When the blocking plate is rotated to a vertical state for blocking the air outlet duct, the spring keeps the blocking plate from moving closer to the air outlet duct.

[0016] By adopting the above technical solution, the rotating rod rotates to drive the positioning block 1 to rotate around the axis of the rotating column. The rotation of the positioning block 1 pushes the spring to rotate. The rotation of the spring drives the positioning block 2 to rotate for adaptation, so that the thrust of the spring on the rotating rod tends to be balanced and stable, so that when the blocking plate is placed on the upper surface of the air outlet pipe, the spring pushes the blocking plate to maintain the state, or when the blocking plate is in a vertical state and presses against the air outlet pipe to block it, the spring also pushes the blocking plate to maintain the state, thereby further improving the stability in the above two working conditions and improving the safety of the reactor.

[0017] Optionally, when the blocking plate is horizontally placed on the upper surface of the air outlet pipe, it partially extends to the outside of the air outlet pipe and is used to prevent rainwater and impurities from entering the air outlet pipe.

[0018] By adopting the above technical solution, rainwater and impurities can be prevented from entering the air outlet duct, the probability of damage to the fan and drive components is reduced, and the safety of the reactor is improved.

[0019] Optionally, a support block is provided on the upper surface of the air outlet duct, and an elastic sealing sheet is provided on the side wall of the sealing plate close to the air outlet duct; when the sealing plate is placed horizontally, the sealing sheet is pressed against the support block for positioning, and when the sealing plate is in a vertical state, the sealing sheet is pressed against the air outlet duct for sealing.

[0020] By adopting the above technical solution, the blocking plate is placed horizontally and pressed against the support block for positioning, so that a certain gap is maintained between the blocking plate and the upper surface of the air outlet pipe, thereby reducing the probability of friction or even collision between the blocking plate and the air outlet pipe during movement, and the sealing sheet has elasticity, which can further reduce the risk of the above situation; and the sealing sheet is pressed against the air outlet pipe for sealing, thereby improving the sealing effect of the air outlet pipe, further improving the fire extinguishing effect, and increasing the life of the reactor.

[0021] Optionally, a filtering mechanism is provided on the air inlet pipe, and the filtering mechanism includes: The filter plate is detachably arranged on the air inlet pipe through a connecting assembly; The cleaning component is connected with the air outlet pipe and uses the air flow generated by the fan to clean the impurities on the filter plate. The connecting component can also collect the impurities dropped from the filter plate.

[0022] By adopting the above technical solution, the filter plate is installed on the air inlet duct through the connecting component, and the cleaning component cleans the impurities on the filter plate in real time through the air in the air outlet duct, and the cleaned impurities fall into the connecting component for collection. Therefore, removing the filter plate can realize the cleaning of impurities in the connecting component, thereby increasing the rate at which air passes through the filter plate, improving the heat dissipation effect in the box, reducing the risk of fire, and improving the safety of the reactor.

[0023] Optionally, a mounting hole is provided on the lower surface of the air inlet pipe, and the connecting assembly includes: A connection box is detachably arranged on the lower surface of the air inlet pipe, and impurities dropped from the filter plate fall into the connection box through the installation hole for collection; A connecting plate is detachably arranged on the lower surface of the connecting box, and the bottom of the filter plate is arranged on the connecting plate and is slidably arranged on the connecting box and extends into the air inlet pipe; The scraper block is arranged on the inner wall of the connection box and is provided with an inclined scraping surface. When the filter plate moves, the scraping surface is used to scrape off the impurities adhering to the filter plate and guide them into the connection box for collection.

[0024] By adopting the above technical scheme, the connecting plate and the connecting box are separated, and the connecting plate is pulled to drive the filter plate to move vertically. The scraper block is used to scrape off impurities adhering to the filter plate, and the fallen impurities are moved to the connecting box through the scraping surface for collection, so as to realize the cleaning of the filter plate, and then the connecting plate is pushed against the connecting box and fixed, and the connecting plate moves up to drive the filter plate to move up to the original position to continue filtering the air, thereby realizing the cleaning of impurities on the filter plate. At the same time, after a period of time, the impurities in the connecting box are cleaned after the connecting box is removed, so that the filter plate can be detachably installed on the air inlet pipe, and at the same time, the filter plate can be cleaned simply and stably, further improving the safety of the reactor.

[0025] Optionally, the cleaning component includes: A cleaning pipe is arranged on the inner wall of the air inlet pipe and is provided with a cleaning hole inclined downward toward the filter plate; The output pipe is arranged on the air outlet pipe and is connected with the cleaning pipe so that air is blown out through the cleaning hole to achieve cleaning. The output pipe is provided with an output valve for controlling opening and closing. After the fire detection component detects a fire, the output valve is closed.

[0026] By adopting the above technical solution, the fan is started, allowing part of the air to enter the output pipe, and then the air is ejected through the cleaning pipe and the cleaning hole to clean the impurities on the filter plate, thereby cleaning the impurities on the filter plate in real time. When the fire detection component detects a fire, the output valve is closed, so that the gas drawn by the fan is removed through the outlet pipe. After the fire risk is eliminated, the fan and the output valve are opened to continue to dissipate heat from the box, thereby improving the safety of the reactor.

[0027] In the second aspect, the magnetically controlled reactor provided in the present application adopts the following technical solution: The magnetically controlled reactor comprises a box body provided with a plurality of electrical components, and a fire extinguishing device as described in the first aspect and arranged on the box body.

When a fire is detected in the box by the fire detection component, the blocking mechanism 1 blocks the air inlet duct first, and the fan continues to start to extract the air in the box. Then the fan is turned off and the blocking mechanism 2 blocks the air outlet duct, so that the outside air cannot enter the box, and the fire point in the box is extinguished due to lack of oxygen, thereby greatly improving the safety of the reactor.

[0029] 2. The air in the box is sucked by the fan, which greatly speeds up the air output in the box, so that the fire point can be extinguished more quickly, further improving the safety of the reactor; and compared with extinguishing the fire by spraying fire extinguishing materials, the above method greatly reduces the probability of fire extinguishing materials causing damage to unburned electrical components, and is also convenient for finding the fire point, thereby facilitating subsequent maintenance and improvement of the equipment, further improving the safety of the reactor.
