Technical Field
[0001] The utility model relates to the technical field of electrical cabinets, in particular to a cellular automated electrical control cabinet capable of flame retardancy and fire extinguishing. Background Art
[0002] The compartmentalized automated electrical control cabinet is a device specially used for industrial automation control. In the compartmentalized automated electrical control cabinet, various electrical components are installed in compartments. Each compartment has clear markings and instructions, which makes it easy for maintenance personnel to quickly find the required components and replace or repair them.
[0003] At present, a Chinese patent discloses a compartmentalized automated electrical control cabinet with flame retardant and fire extinguishing function (publication number CN216648892U). The smoke sensor on the corresponding partition can monitor the smoke and start the solenoid valve at the corresponding position. At this time, the solenoid valve can be started to spray the dry ice inside the output pipe to the corresponding position through the nozzle. Since dry ice is used for fire extinguishing, the dry ice is gasified into carbon dioxide and will not affect the components, and the layered fire extinguishing will not interfere with other parts.
[0004] According to the above reference materials, the above device uses dry ice to extinguish the electrical components in the corresponding compartments. However, when the dry ice evaporates into gaseous carbon dioxide, the air pressure inside the cabinet will increase, and the resistance of the staff to subsequent door opening for maintenance will also increase. Moreover, since gaseous carbon dioxide is an asphyxiating gas, it will be filled in the surrounding air after the cabinet is opened, which can easily endanger the safety of the surrounding staff.
[0005] Therefore, a cellular automated electrical control cabinet capable of flame retardancy and fire extinguishing is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a flame retardant and fire extinguishing compartmented automatic electrical control cabinet in order to solve the above problems, thereby improving the problem that the existing flame retardant and fire extinguishing compartmented automatic electrical control cabinet is difficult for staff to maintain after the fire is extinguished and has low practicality.
[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, which is a flame-retardant and fire-extinguishing compartmented automatic electrical control cabinet, comprising: a cabinet body, the interior of which is provided with evenly distributed compartment grooves, the top of which is fixedly connected with a fire extinguishing device, the end of which passes through the cabinet body and extends to the interior of the compartment grooves; a collecting device, which is used to collect waste gas after fire extinguishing and is installed inside the cabinet body.
[0008] Preferably, an installation cavity is provided on the surface of the cabinet, and the collecting device includes an air pump fixedly connected to the bottom wall of the installation cavity, the air inlet end of the air pump passes through the installation cavity and extends to the interior of the lowest dividing groove, and the air outlet end of the air pump is fixedly connected and communicated with a connecting mechanism, one end of the connecting mechanism is fixedly connected and communicated with a gas tank. The staff can collect the sunken gaseous carbon dioxide together through the collecting device, which can not only reduce the air pressure inside the cabinet, so that the air pressure inside the cabinet can quickly return to normal, so as to facilitate the subsequent opening operation of the staff, but also can reduce the leakage of gaseous carbon dioxide to the outside, thereby reducing the impact on surrounding staff.
[0009] Preferably, the connecting mechanism includes an internal threaded tube fixedly connected and connected to the air outlet end of the air pump, and the inner wall of the internal threaded tube is threadedly connected to an external threaded tube fixedly connected and connected to the gas tank. When the staff needs to deal with the exhaust gas inside the gas tank, the staff can unscrew the external threaded tube out of the internal threaded tube by rotating the direction, so that the gas tank loses connection with the air pump, making it more convenient for the staff to deal with the exhaust gas.
[0010] Preferably, a sealing gasket is provided inside the internal threaded pipe, and the sealing gasket is arranged between the air pump and the external threaded pipe, which can increase the connection tightness between the internal threaded pipe and the external threaded pipe, thereby reducing the probability of exhaust gas leakage.
[0011] Preferably, one end of the internal threaded pipe is fixedly connected and communicated with an opening and closing valve, and one end of the opening and closing valve is fixedly connected and communicated with the gas tank. This can confine the collected waste gas inside the gas tank, reducing the probability of waste gas leakage during the removal of the gas tank by the staff, making the waste gas treatment work of the staff safer.
[0012] Preferably, the collection device also includes a pressure gauge fixedly connected to the top wall of the installation cavity, and the top of the pressure gauge passes through the installation cavity and extends to the interior of the lowest partition groove, which can detect the air pressure inside the cabinet in real time so that the staff can accurately extract the exhaust gas through the air pump.
[0013] Preferably, a dustproof net is fixedly connected to the air inlet end of the air pump and the top of the barometer, and the top of the dustproof net is flush with the inner bottom wall of the lowest dividing groove, which can prevent dust inside the cabinet from falling into the air pump and the barometer, so as to ensure that the air pump and the barometer can operate normally.
[0014] Preferably, the collecting device further comprises a support sleeve fixedly connected to the inner wall of the mounting cavity, and the support sleeve is slidably connected to the surface of the gas tank, which enables the gas tank to operate more smoothly and reduces the use burden of the connecting mechanism.
[0015] Preferably, the cross-sectional size of the on-off valve is smaller than the cross-sectional size of the support sleeve, which can ensure that the on-off valve can also be moved to the outside of the support sleeve along with the gas tank to ensure that the gas tank can be disassembled normally.
[0016] The beneficial effects of the utility model are:
[0017] 1. The staff can collect the sinking gaseous carbon dioxide through the collection device, which can not only reduce the air pressure inside the cabinet, so that the air pressure inside the cabinet can quickly return to normal, so as to facilitate the subsequent opening operation of the staff, but also reduce the leakage of gaseous carbon dioxide to the outside, thereby reducing the impact on the surrounding staff;
[0018] 2. When the staff needs to deal with the exhaust gas inside the gas tank, the staff can rotate the external threaded pipe out of the internal threaded pipe to make the gas tank lose connection with the air pump, making it more convenient for the staff to deal with the exhaust gas. The opening and closing valve design can limit the collected exhaust gas to the inside of the gas tank, reducing the probability of exhaust gas leakage during the removal of the gas tank, making the exhaust gas treatment work of the staff safer.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] When implementing: Figure 1-4 As shown, a flame retardant and fire extinguishing compartmented automatic electrical control cabinet comprises: a cabinet 1, the interior of the cabinet 1 is provided with evenly distributed compartment slots 11, the top of the cabinet 1 is fixedly connected with a fire extinguishing device 2, the end of the fire extinguishing device 2 passes through the cabinet 1 and extends to the interior of the compartment slot 11; a collecting device 3, the collecting device 3 for collecting waste gas after fire extinguishing is installed inside the cabinet 1;
[0026] The fire extinguishing device 2 includes a dry ice fire extinguisher, a smoke sensor and a controller with the same number as the sub-dividing slots 11, the dry ice fire extinguisher and the controller are fixedly connected to the top of the cabinet 1, the smoke sensor is fixedly connected to the top of the sub-dividing slot 11, the end of the dry ice fire extinguisher is fixedly connected to an electric can opener, the end of the electric can opener is fixedly connected and connected to a first connecting pipe, the surface of the first connecting pipe is fixedly connected and connected to an electromagnetic valve, the end of the electromagnetic valve is fixedly connected and connected to a second connecting pipe, the end of the second connecting pipe passes through the cabinet 1 and extends to the inside of the corresponding sub-dividing slot 11; when the smoke sensor detects smoke inside the sub-dividing slot 11, the surface of the electrical inside the sub-dividing slot 11 is turned on. When the equipment catches fire, the corresponding signal of the smoke alarm is transmitted to the controller. The controller controls the opening of the electric can opener and the corresponding solenoid valve according to the preset instructions. At this time, the electric can opener opens the dry ice fire extinguisher. At this time, the high-pressure dry ice flows along the first connecting pipe and the corresponding solenoid valve into the corresponding second connecting pipe. The second connecting pipe guides the dry ice to the corresponding dividing groove 11. The dry ice quickly covers the surface of the electrical equipment and quickly vaporizes into gaseous carbon dioxide. In this process, the heat generated by the electrical equipment is quickly absorbed, so that the temperature at the fire site is rapidly reduced. At the same time, the gaseous carbon dioxide squeezes out the combustion-supporting gas around the electrical equipment, making it difficult to maintain combustion at the fire site, thereby achieving the purpose of extinguishing the fire.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, a mounting cavity 12 is provided on the surface of the cabinet 1, and the collecting device 3 includes an air pump 31 fixedly connected to the inner bottom wall of the mounting cavity 12, the air inlet end of the air pump 31 passes through the mounting cavity 12 and extends to the interior of the lowest partition groove 11, the air outlet end of the air pump 31 is fixedly connected and communicated with a connecting mechanism 33, one end of the connecting mechanism 33 is fixedly connected and communicated with a gas tank 32; the collecting device 3 also includes a pressure gauge 34 fixedly connected to the inner top wall of the mounting cavity 12, the top of the pressure gauge 34 passes through the mounting cavity 12 and extends to the interior of the lowest partition groove 11; a dustproof net 35 is fixedly connected to the air inlet end of the air pump 31 and the top of the pressure gauge 34, and the top of the dustproof net 35 is flush with the inner bottom wall of the lowest partition groove 11; the collecting device 3 also includes a support sleeve 36 fixedly connected to the inner wall of the mounting cavity 12, and the support sleeve 36 is slidably connected to the surface of the gas tank 32.
[0028] like Figure 4As shown, the connection mechanism 33 includes an internal threaded tube 331 fixedly connected and connected to the air outlet end of the air pump 31, and the inner wall of the internal threaded tube 331 is threadedly connected with an external threaded tube 332 fixedly connected and connected to the air tank 32; a sealing gasket 333 is arranged inside the internal threaded tube 331, and the sealing gasket 333 is arranged between the air pump 31 and the external threaded tube 332; one end of the internal threaded tube 331 is fixedly connected and connected with an opening and closing valve 334, and one end of the opening and closing valve 334 is fixedly connected and connected to the air tank 32; the cross-sectional size of the opening and closing valve 334 is smaller than the cross-sectional size of the support sleeve 36;
[0029] When the staff needs to take out the gas tank 32 containing waste gas, the staff first closes the opening and closing valve 334, and then rotates the gas tank 32 in the corresponding direction. The gas tank 32 drives the external threaded tube 332 to be screwed out of the internal threaded tube 331 through the opening and closing valve 334. Finally, the staff moves the gas tank 32 together with the opening and closing valve 334 out of the support sleeve 36. At this time, the staff can easily take out the gas tank 32 for subsequent processing.
[0030] According to the utility model, when the staff needs to open the cabinet 1 after the fire is extinguished, the staff needs to wait for a specified time to allow the gaseous carbon dioxide with a density greater than that of air to sink to the lowest dividing groove 11, and then the staff only needs to turn on the air pump 31, and the air pump 31 will suck the sinking gaseous carbon dioxide into the gas tank 32 for centralized storage. This can not only reduce the air pressure inside the cabinet 1, but also quickly restore the air pressure inside the cabinet 1 to normal, so as to facilitate the subsequent opening operation of the staff, and at the same time, it can also reduce the leakage of gaseous carbon dioxide to the outside, thereby reducing the impact on surrounding staff.
[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
