Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet safety, and particularly relates to a self-inductive cabinet fire-extinguishing tube fire extinguishing system. Background Art

[0002] As the total control of the equipment lines in a building, the safety of the power distribution cabinet is of utmost importance. The fire-extinguishing tube fire extinguishing device is a simple, low-cost and highly reliable automatic fire extinguishing system, which is widely used in systems such as power plants, communications, radio and television, petrochemicals, railways, oil storage depots, computer rooms, etc., and solves the long-standing fire prevention problems in spaces prone to fire hazards such as electrical equipment, control boxes, and switchboards in the fire protection industry. Therefore, the fire-extinguishing tube fire extinguishing device is often used to solve the fire prevention problem of the power distribution cabinet at present. However, it is found in actual application that although the fire-extinguishing tube fire extinguishing device can accurately spray the fire-spraying substance to the ignition point when a fire hazard occurs in the power distribution cabinet, there is still a possibility that the power distribution cabinet will catch fire again after being extinguished. And when the power distribution cabinet catches fire again after being extinguished, the fire-extinguishing tube fire extinguishing device cannot extinguish the fire again. In this way, if it is not discovered in time, the power distribution cabinet is very likely to develop into a serious fire accident. Therefore, there are still relatively large potential safety hazards in the current fire safety of the power distribution cabinet, which needs to be further improved. Content of the Utility Model

[0003] In view of the above, it is necessary to provide a self-inductive cabinet fire-extinguishing tube fire extinguishing system, which uses the setting of the fire-extinguishing tube fire extinguishing device to achieve the extinguishment of the first initial fire. If the extinguishment of the initial fire fails, the immersion gas fire extinguishing equipment is used for secondary extinguishment. The performance design of dual extinguishment, combined with the monitoring function of the on-site camera monitoring device, greatly improves the reliability of extinguishment and ensures the fire safety of the power distribution cabinet.

[0024] The following specific embodiments will further illustrate the utility model in conjunction with the above-mentioned drawings. Specific Embodiments

[0025] Please refer to Figure 1-2 , in a preferred embodiment of the utility model, a self-inductive cabinet fire-extinguishing system with a fire-detecting tube includes a plurality of fire-detecting tube fire-extinguishing devices 2, a submerged gas fire-extinguishing equipment, a camera monitoring device and a remote control terminal.

[0026] A fire detection tube fire extinguishing device 2 is matched with a power distribution cabinet 1. The main body of the fire detection tube fire extinguishing device 2 is arranged outside the power distribution cabinet 1. The fire detection tube 2.2 of the fire detection tube fire extinguishing device 2 extends from outside the power distribution cabinet 1 to the inside of the power distribution cabinet 1 and is laid on the inner side of the power distribution cabinet 1. Specifically, it is wound around the equipment of the power distribution cabinet 1 so that all the equipment of the power distribution cabinet 1 can be covered. When a fire hazard occurs in any one of the equipment, the corresponding position of the fire detection tube 2.2 is punctured, and then the fire extinguishing medium is ejected onto the equipment to achieve fire extinguishing. Here, it should be noted that the fire detection tube fire extinguishing device 2 is an existing device, and its working principle and specific structure are not given in detail here.

[0027] The immersion gas fire extinguishing equipment includes a gas fire extinguishing agent cylinder 3, an immersion gas control main valve 4, a gas fire extinguishing main pipe 5, a plurality of gas fire extinguishing branch pipes 7, and an immersion gas control sub-valve 6. The outlet of the gas fire extinguishing agent cylinder 3 is installed with the gas fire extinguishing main pipe 5. The immersion gas control main valve 4 is arranged on the gas fire extinguishing main pipe 5. A plurality of immersion gas control sub-valves 6 are installed on the gas fire extinguishing main pipe 5 at intervals. One immersion gas control sub-valve 6 is connected to one gas fire extinguishing branch pipe 7. The gas fire extinguishing branch pipe 7 is movably connected to the gas fire extinguishing main pipe 5 through an electric telescopic structure 8. Each gas fire extinguishing branch pipe 7 is matched with a power distribution cabinet 1. One end of the gas fire extinguishing branch pipe 7 that is not connected to the immersion gas control sub-valve 6 extends into the power distribution cabinet 1 through a through hole 1.1 on the power distribution cabinet 1 or moves outside the power distribution cabinet 1 under the action of the electric telescopic structure 8. In the present utility model, the immersion gas fire extinguishing equipment can extinguish the fire of the power distribution cabinet 1 by the way of gas submerging the internal space of the power distribution cabinet 1. This immersion gas fire extinguishing equipment is used in the case that the fire extinguishing of the fire detection tube fire extinguishing device 2 is not successful at one time or reignites. It is a secondary fire extinguishing equipment, so that the power distribution cabinet 1 has a double fire extinguishing protection function and improves the fire safety of the power distribution cabinet 1. In the immersion gas fire extinguishing equipment of the present utility model, through the arrangement of a plurality of gas fire extinguishing branch pipes 7 and immersion gas control sub-valves 6, each power distribution cabinet 1 in the computer room independently has a fire extinguishing device. When a fire hazard occurs in a certain power distribution cabinet 1, the corresponding gas fire extinguishing branch pipe 7 is driven to extend into the power distribution cabinet 1, and the corresponding immersion gas control sub-valve 6 is opened. In this way, the fire extinguishing actions of each power distribution cabinet 1 do not interfere with each other. In this embodiment, the immersion gas control main valve 4 is installed at the bottle mouth of the gas fire extinguishing agent cylinder 3, and it is used to control the flow of the fire extinguishing gas in total. The gas fire extinguishing branch pipe 7 includes a hose section and a hard pipe section. One end of the hose section is connected to the immersion gas control sub-valve 6, and the other end is connected to the hard pipe section. The hard pipe section is connected to the telescopic end of the electric telescopic structure 8. One end of the hard pipe section that is not connected to the hose section moves inside and outside the power distribution cabinet 1 under the action of the electric telescopic structure 8. In another embodiment of the present utility model, the gas fire extinguishing branch pipe 7 can also be a telescopic pipe structure (not shown in the figure), its fixed section is connected to the immersion gas control sub-valve 6, and the telescopic section is connected to the telescopic end of the electric telescopic structure 8. In addition, the electric telescopic structure 8 of the present utility model is preferably an electric push rod. In order to make the secondary fire extinguishing effect of the power distribution cabinet 1 better and facilitate the movement of the gas fire extinguishing branch pipe 7, the aperture of the through hole 1.1 on the power distribution cabinet 1 is larger than the pipe diameter of the gas fire extinguishing branch pipe 7. Preferably, a sealed cover plate 9 is arranged on the gas fire extinguishing branch pipe 7. The sealed cover plate 9 is located outside the power distribution cabinet 1. The sealed cover plate 9 opens and closes the through hole 1.1 on the power distribution cabinet 1 under the action of the electric telescopic structure 8. In this way, when the gas fire extinguishing branch pipe 7 extends into the power distribution cabinet 1 and reaches the preset position under the action of the electric telescopic structure 8, the sealed cover plate 9 covers the through hole 1.1.

[0028] The camera monitoring device is installed outside the power distribution cabinet 1 and is used to monitor all the power distribution cabinets 1 to achieve on-site monitoring. Preferably, the camera of the camera monitoring device is a 360° rotating camera, which is convenient for monitoring all the power distribution cabinets 1.

[0029] The remote control terminal is respectively connected to the fire detection tube fire extinguishing device 2, the total submerged gas control valve 4, each submerged gas control sub-valve 6, each electric telescopic structure 8 and the camera monitoring device through a wireless transmission module, so as to control the equipment in the machine room through the remote control terminal. For example, after the fire detection tube fire extinguishing device 2 is started, the pressure sensor 2.1 of the fire detection tube fire extinguishing device 2 will transmit the monitored pressure value to the remote control terminal through the wireless transmission module. When the remote control terminal receives this pressure value, it can know which power distribution cabinet 1 has a fire hazard (because each pressure sensor 2.1 has an address module, and through the address module information, it can be known which fire detection tube fire extinguishing device 2 at which position is opened, so as to determine which power distribution cabinet 1). The remote control terminal remotely transmits an instruction to the camera monitoring module to turn on the imaging function of the camera monitoring module. The camera monitoring module will transmit the image information of this power distribution cabinet 1 to the remote control terminal in real time. The remote control terminal can analyze whether the fire hazard has been resolved based on the image information, or the staff of the remote control terminal can make a judgment based on the image information transmitted back by the camera monitoring module displayed on the remote control terminal. When it is analyzed that the fire hazard of the power distribution cabinet 1 has been resolved, the remote control terminal sends an instruction to the fire control room to replace the fire extinguishing equipment. When it is analyzed that the fire hazard of the power distribution cabinet 1 still exists, the remote control terminal sends a control instruction to the submerged gas fire extinguishing equipment to start the operation of the electric telescopic structure 8 corresponding to the power distribution cabinet 1 so that the corresponding gas fire extinguishing branch pipe 7 extends into the power distribution cabinet 1, and then starts the corresponding submerged gas control sub-valve 6 and the total submerged gas control valve 4 to open. The gas fire extinguishing medium ejected by the submerged gas fire extinguishing equipment submerges the space in the power distribution cabinet 1 to achieve secondary fire extinguishing. After the fire extinguishing is completed, the remote control terminal sends an instruction to the fire control room to replace the fire extinguishing equipment.

[0030] Furthermore, the self-inductive cabinet fire detection tube 2.2 fire extinguishing system further includes a on-site alarm device. The on-site alarm device is installed outside the power distribution cabinet 1 and is wirelessly connected to the remote control terminal through a wireless transmission module, so as to timely remind the staff near the power distribution room by means of the on-site alarm device sending an alarm.

[0031] In addition, the self-inductive cabinet fire detection tube 2.2 fire extinguishing system further includes a monitoring alarm device. The monitoring alarm device is arranged beside the remote control terminal and is communicatively connected to the remote control terminal, so as to timely remind the staff near the remote monitoring terminal by means of the monitoring alarm device sending an alarm.

[0032] For the present utility model, the remote control terminal may be a security and fire linkage platform or other control terminal platforms. The on-site alarm device may include a fire alarm host and an audible and visual alarm. The monitoring alarm device may be an audible and visual alarm or other signal-type alarms.

[0033] The working principle of the present utility model is as follows:

[0034] 1. When an electric spark or combustion occurs in the power distribution cabinet 1, it touches the fire detection tube 2.2 of the fire detection tube fire extinguishing device 2 in the power distribution cabinet 1. After the pipeline of the fire detection tube 2.2 is damaged, the fire extinguishing medium released from the main body of the fire detection tube fire extinguishing device 2 acts directly on the ignition point from the damaged part;

[0035] 2. After the pressure sensor at the gas cylinder valve in the main body of the fire detection tube fire extinguishing device 2 senses the gas release, it starts the switch quantity signal and synchronously feeds it back to the on-site alarm device. The on-site alarm device issues an alarm. At the same time, the pressure sensor also feeds the signal back to the remote control terminal. The remote control terminal drives the monitoring alarm device to issue an alarm, remotely sends a control instruction to the camera monitoring device to turn on the monitoring, and displays the gas fire extinguishing release position. The monitoring system jumps to display the on-site image fed back by the camera monitoring device.

[0036] 3. Confirm the on-site fire situation through the on-site image. If the fire has been successfully extinguished by the fire detection tube fire extinguishing device 2, the remote terminal device displays that the fire extinguishing is successful and sends an instruction to the fire control room to replace the fire extinguishing equipment by fire maintenance; if the on-site fire detection tube fire extinguishing device 2 is not sufficient to extinguish the fire or there is a re-ignition on the site, the remote control terminal sends an instruction to the submerged gas fire extinguishing equipment or the staff beside the remote control terminal can also manually start remotely. Start the electric telescopic structure 8 of the corresponding power distribution cabinet 1 to operate so that the corresponding gas fire extinguishing branch pipe 7 extends into the power distribution cabinet 1, and then start the corresponding submerged gas control sub-valve 6 and submerged gas control main valve 4 to open. The gas fire extinguishing medium ejected by the submerged gas fire extinguishing equipment submerges the space in the power distribution cabinet 1 for secondary fire extinguishing.

[0037] The above description is a detailed description of the preferred and feasible embodiments of the present utility model, but the embodiments are not intended to limit the scope of the patent application of the present utility model. Any equivalent changes or modifications made under the technical spirit disclosed by the present utility model shall fall within the scope of the patent covered by the present utility model.
