Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power fire prevention, and particularly relates to an electric power fire prevention protection device. Background Technique
[0002] Electric power fire prevention refers to the measures and technologies for preventing the occurrence of fires or reducing the impact of fires on electric power facilities and operations in the electric power system. In the electric power system, fire prevention work is crucial because fires can not only cause equipment damage and power outages, but also have a serious impact on personnel safety and the environment.
[0003] In electric power fire prevention, it mainly includes the application of fireproof materials, regular maintenance and inspection of electric power equipment, fire detection and alarm, and fire extinguishing systems. For example, in the fire extinguishing system, when a fault occurs in an electric power equipment and catches fire, it can timely extinguish the open fire to avoid the occurrence of a fire. However, in common fire extinguishing systems, there are intelligent electric control fire extinguishing systems (such as open fire detectors, temperature sensors, etc. to monitor electric power equipment, and automatically start the fire extinguishing device to extinguish the electric power equipment when there is an open fire or a higher temperature to prevent the occurrence of a fire) and physical automatic fire extinguishing (such as fire sprinkler heads, etc., which automatically spray water to extinguish the fire when the temperature reaches). However, both of these two fire extinguishing systems have certain drawbacks. If the electric control fire extinguishing system damages its circuit when the electric power equipment catches fire, the fire extinguishing device cannot work and cannot effectively extinguish the fire. And the physical automatic fire extinguishing will work only after reaching a certain temperature, and its fire extinguishing has a lag, which cannot play the role of timely extinguishing the fire and is easy to expand the loss. Content of the Utility Model
[0004] In view of the problems existing in the prior art, the utility model discloses an electric power fire prevention protection device, and the technical scheme adopted is that it includes a fire extinguishing bucket, a control module, an open fire detector and a temperature sensor are fixedly installed on the plane on the side of the fire extinguishing bucket, and a fire prevention mechanism is installed in the fire extinguishing bucket;
[0005] The fire prevention mechanism includes a partition board, a communication hole, a solenoid valve, a metal shaping hose, a spray nozzle, a heat-sensitive glass column and a baffle. The partition board is fixedly installed inside the fire extinguishing bucket, dividing the fire extinguishing bucket into upper and lower parts. At least three communication holes are opened at the top of both ends of the partition board. Compressed air is arranged on the upper side of the partition board, and dry powder is arranged on the lower side of the partition board. There are two metal shaping hoses. The upper ends of the two shaping hoses are connected to two discharge ports on the side of the fire extinguishing bucket, and the lower ends of the two metal shaping hoses are respectively connected to the feed ports of two spray nozzles. A solenoid valve is installed on one of the metal shaping hoses. A baffle is detachably installed on the end surface of the spray nozzle connected to the other metal shaping hose through screws. A heat-sensitive glass column is movably installed in the feed port of this spray nozzle. The outer end of the heat-sensitive glass column contacts the side surface of the baffle. The open fire detector, the temperature sensor and the solenoid valve are electrically connected to the control module.
[0006] As a preferred technical solution of the present utility model, the end faces at both ends of the fire extinguishing bucket are respectively fixedly connected to the side faces at both ends of the U-shaped mounting plate, and mounting holes are provided on the side faces at both ends of the mounting plate.
[0007] As a preferred technical solution of the present utility model, L-shaped spray pipes are fixedly installed at the bottoms of both ends of the partition board, and the upper ends of the two spray pipes are respectively connected to the communication holes in the middle of both ends of the partition board.
[0008] As a preferred technical solution of the present utility model, a storage battery is fixedly installed on the side face in the middle of the mounting plate, and the storage battery is electrically connected to the control module.
[0009] As a preferred technical solution of the present utility model, the air inlet on the end face of the fire extinguishing bucket is connected to one end of the air inlet pipe, and a one-way valve is installed on the air inlet pipe.
[0010] As a preferred technical solution of the present utility model, the feed inlet in the middle of the top of the partition board is connected to one end of the powder adding pipe, the other end of the powder adding pipe extends to the outside of the fire extinguishing bucket, and the outer end of the powder adding pipe is threadedly connected to the sealing cover.
[0011] Advantages of the present utility model:
[0012] 1. When an electrical fire occurs in the present utility model, if the control circuit is not damaged by the fire, when the open fire detector and the temperature sensor detect open fire and high temperature, the solenoid valve is automatically controlled to open. At this time, the compressed air on the upper side of the partition board will drive the dry powder on the lower side of the partition board to be ejected from the metal shaping hose and the spray nozzle towards the ignition point, achieving rapid fire extinguishing. When the control circuit is damaged during a fire, after the fire reaches a certain temperature, the heat-sensitive glass column in the spray nozzle will burst, causing the compressed air on the upper side of the partition board to drive the dry powder on the lower side of the partition board to be ejected from the metal shaping hose and the spray nozzle towards the ignition point for fire extinguishing, preventing the occurrence of fires. Through the complementarity of electric control automatic fire extinguishing and physical automatic fire extinguishing, the problem that the electric control automatic fire extinguishing circuit is damaged and unable to extinguish fires and the problem of untimely physical fire extinguishing are solved, improving the stability of electric power fire extinguishing, thereby preventing the occurrence of electric power fires.
[0013] 2. The fire extinguishing bucket can be fixedly installed at the main position of the electrical equipment through the mounting holes on the mounting plate, and combined with the bendability of the metal shaping hose, the spray nozzle can be oriented towards the position where open fire is likely to occur on the electrical equipment. Part of the compressed air can be guided to the bottom inside the fire extinguishing bucket through the spray pipe to prevent the dry powder inside the fire extinguishing bucket from not being completely ejected to the outside. The storage battery can provide power when the power is cut off during a fire, enabling the electric control automatic fire extinguishing part to work normally after the power is cut off.
[0014] 3. Compressed air can be filled into the fire extinguishing bucket through the air inlet pipe and the one-way valve, and dry powder can be added into the fire extinguishing bucket through the powder adding pipe. Combined with the detachable design of the baffle plate, the entire electric fire protection device can be reused, reducing the overall cost. Description of the Drawings

A storage battery 12 is fixedly installed on the side face in the middle of the mounting plate 9. The storage battery 12 is electrically connected to the control module 2. The storage battery 12 can provide power when the power is cut off due to a fire, enabling the electric control automatic fire extinguishing part to work normally after the power is cut off. The air inlet on the end face of the fire extinguishing bucket 1 is connected to one end of an air inlet pipe 13. A check valve 14 is installed on the air inlet pipe 13. The feed inlet in the middle of the top of the partition plate 51 is connected to one end of a powder adding pipe 15. The other end of the powder adding pipe 15 extends to the outside of the fire extinguishing bucket 1. The outer end of the powder adding pipe 15 is threadedly connected to a sealing cover 16. Compressed air 6 can be filled into the fire extinguishing bucket 1 through the air inlet pipe 13 and the check valve 14. Dry powder can be added into the fire extinguishing bucket 1 through the powder adding pipe 15. In cooperation with the detachable design of the baffle 57, the entire power fire protection device can be reused, reducing the overall cost;The fire prevention mechanism 5 includes a partition plate 51, communication holes 52, a solenoid valve 53, a metal shaping hose 54, a spray nozzle 55, a heat-sensitive glass column 56, and a baffle 57. The partition plate 51 is fixedly installed inside the fire extinguishing barrel 1, dividing the fire extinguishing barrel 1 into upper and lower parts. At least three communication holes 52 are provided at the top of both ends of the partition plate 51. Compressed air 6 is arranged on the upper side of the partition plate 51. L-shaped spray pipes 11 are fixedly installed at the bottom of both ends of the partition plate 51. The upper ends of the two spray pipes 11 are respectively connected to the communication holes 52 in the middle of both ends of the partition plate 51. Through the spray pipes 11, part of the compressed air 6 can be guided to the inner bottom of the fire extinguishing barrel 1 to prevent the dry powder 7 in the fire extinguishing barrel 1 from not being completely sprayed out to the outside. Dry powder 7 is arranged on the lower side of the partition plate 51. There are two metal shaping hoses 54. The upper ends of the two shaping hoses 54 are connected to the two discharge ports on the side of the fire extinguishing barrel 1. The lower ends of the two metal shaping hoses 54 are respectively connected to the feed ports of the two spray nozzles 55. A solenoid valve 53 is installed on one of the metal shaping hoses 54. A baffle 57 is detachably installed on the end face of the spray nozzle 55 connected to the other metal shaping hose 54 through a screw 8.

The flame detector 3, the temperature sensor 4, and the solenoid valve 53 are electrically connected to the control module 2. When an electrical fire occurs and the control circuit is not damaged by the fire, when the flame detector 3 and the temperature sensor 4 detect a fire and a high temperature, the solenoid valve 53 is automatically controlled to open.

When the control circuit is damaged during a fire, after the fire reaches a certain temperature, the heat-sensitive glass column 56 in the spray nozzle 55 will burst, causing the compressed air 6 on the upper side of the partition plate 51 to drive the dry powder 7 on the lower side of the partition plate 51 to be sprayed out from the metal shaping hose 54 and the spray nozzle 55 towards the fire point for fire extinguishing, preventing the occurrence of a fire.

[0022] Working principle of the utility model: Fix the fire extinguishing bucket 1 on or beside the power equipment through the mounting holes 10 on the mounting plate 9. Bend the metal shaping hose 54 so that the spray nozzle 55 faces the easily ignitable part of the power equipment. When the open fire detector 3 monitors that the power equipment has a short circuit and catches fire, the control module 2 will automatically control the solenoid valve 53 to open. At this time, the compressed air 6 on the partition plate 51 will enter the lower side of the partition plate 51 through the communication hole 52, and drive the dry powder 7 to be ejected from the shaping hose 54 and the spray nozzle 55, so that the dry powder 7 is sprayed on the ignition point of the power equipment to timely extinguish the open fire, thereby preventing the occurrence of a fire. If the control circuit is damaged by the open fire during the fire, as the temperature of the open fire rises, the heat-sensitive glass column 56 in the feed port of the spray nozzle 55 will break. At this time, the compressed air 6 in the fire extinguishing bucket 1 will drive the dry powder 7 to be ejected from another metal shaping hose 54 and the spray nozzle 55, so that the ejected dry powder 7 extinguishes the open fire, thereby avoiding the spread of the fire and preventing the occurrence of a fire. After the fire is extinguished, the screws 8 at both ends of the baffle 57 can be removed, the baffle 57 can be taken off, a new heat-sensitive glass column 56 can be inserted into the feed port of the spray nozzle 55, and the baffle 57 can be fixed on the spray nozzle 55 through the screws 8 to block and fix the heat-sensitive glass column 56. Unscrew the sealing cover 16, add the dry powder 7 from the powder adding pipe 15 to the lower side of the partition plate 51, and add compressed air 6 to the fire extinguishing bucket 1 through the air inlet pipe 13, so that the entire power fire extinguishing device can monitor and extinguish the power equipment again.
