Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguishers and discloses a hanging type fire extinguisher. Background Art
[0002] Hanging fire extinguishers are auxiliary equipment of fire fighting systems and are widely used in local fires in places such as ships and power distribution rooms. Hanging fire extinguishers are equipped with a shell for storing fire extinguishing materials. The shell is equipped with a pressure gauge for monitoring the pressure of fire extinguishing materials inside the extinguisher. Hanging fire extinguishers are usually installed on the ceiling of the roof. When a fire occurs, the hanging fire extinguisher can automatically start to extinguish the fire. The fire extinguishing materials are usually sprayed downward from the nozzle under the shell of the fire extinguisher. When the fire site is unmanned, a certain fire control effect can be achieved to ensure the safety of the installation site.
[0003] However, the existing hanging fire extinguishers are usually equipped with a single nozzle, and the single nozzle sprays fire extinguishing materials, which limits the fire extinguishing range. In addition, the fire extinguishing direction of the existing hanging fire extinguishers is usually vertically downward, which makes it difficult to extinguish the fire in a more targeted direction, and the fire extinguishing effect is limited. Utility Model Content
[0004] The purpose of the utility model is to provide a hanging fire extinguisher in view of the above-mentioned problems and shortcomings, which can increase the fire extinguishing range and extinguish fire in a targeted manner, thereby effectively improving the fire extinguishing effect.
[0005] A suspended fire extinguisher comprises a housing, a vacuum pump connected to the interior of the housing is installed below the housing;
[0006] Temperature sensors are provided at the front, rear, left and right ends of the shell; a connecting pipe is connected to the bottom of the vacuum pump; discharge pipes are connected to the front, rear, left and right sides of the lower end of the connecting pipe; a nozzle is connected to the outer end of the discharge pipe; a solenoid valve is installed outside the discharge pipe; a PLC controller is installed above the shell; and an alarm component is provided outside the shell.
[0007] Preferably, the upper left and right ends of the shell are connected to mounting plates, the front, rear, left and right ends of the shell are connected to mounting rods, and the temperature sensor is mounted on the mounting rods on the same side.
[0008] Preferably, lower mounting plates are connected between the front, rear, left, and right ends below the shell and the discharge pipe on the same side, and a smoke sensor is installed on one of the lower mounting plates.
[0009] Preferably, the alarm assembly includes an antenna, an alarm light and a pressure gauge, an upper mounting plate is connected to the right side of the shell, and the antenna and the alarm light are respectively mounted on the upper and lower sides of the upper mounting plate.
[0010] Preferably, the pressure gauge is installed on the housing, and the antenna, warning light, temperature sensor, vacuum pump, smoke sensor, solenoid valve and pressure gauge are all connected to the PLC controller signal.
[0011] The beneficial effects of the utility model are as follows:
[0012] The smoke sensor can sense the smoke, and the PLC controller can control the vacuum pump and temperature sensor to start working and control the solenoid valve to open. At this time, the vacuum pump can suck the fire extinguishing material inside the shell and spray it out through the connecting pipe, the discharge pipe and the nozzle in sequence. At this time, the nozzles on the front, back, left and right sides can spray the fire extinguishing material from the ceiling above to the front, back, left and right sides, thereby increasing the fire extinguishing range and improving the efficiency of fire extinguishing.
[0013] The temperature sensor corresponds to the solenoid valve on the same side. The PLC controller controls the solenoid valve on the side with the highest temperature among the four temperature sensors to increase its opening, and controls the opening of the remaining solenoid valves to decrease, so that more fire extinguishing materials are sprayed out from the side with the highest temperature. The temperature at the fire location is higher than that at other locations. Spraying more fire extinguishing materials on the side where the fire occurs can extinguish the fire more specifically and improve the fire extinguishing effect. The setting of the temperature sensor and the solenoid valve can increase the fire extinguishing range and extinguish the fire specifically, effectively improving the fire extinguishing effect.

DETAILED DESCRIPTION
[0018] like Figures 1 to 3As shown, the present application is a suspended fire extinguisher, comprising a shell 1, a vacuum pump 8 connected to the inside of the shell 1 is installed below the shell 1, temperature sensors 7 are provided at the front, rear, left and right ends of the shell 1, a connecting pipe 11 is connected below the vacuum pump 8, a discharge pipe 13 is connected to the front, rear, left and right sides of the lower end of the connecting pipe 11, a nozzle 14 is connected to the outer end of the discharge pipe 13, a solenoid valve 15 is installed outside the discharge pipe 13, a PLC controller 2 is installed above the shell 1, and an alarm component is provided outside the shell 1;
[0019] The upper left and right ends of the housing 1 are connected to mounting plates, and the front, rear, left and right ends of the housing 1 are connected to mounting rods 6;
[0020] When the hanging fire extinguisher is in use, the housing 1 is used to store fire extinguishing materials, such as Figure 1 As shown, the mounting plate is set in an L shape and is respectively located at the left and right ends above the shell 1. The bolts pass through the mounting plate and the suspended fire extinguisher is installed as a whole at the desired position of the ceiling through the bolts, so as to achieve a stable installation effect. At this time, the temperature sensors 7 located on the front, back, left and right sides of the shell 1 on the ceiling can detect the air temperature on the front, back, left and right sides of the shell 1, which is convenient for subsequent fire extinguishing;
[0021] The temperature sensor 7 is mounted on the mounting rod 6 on the same side, and lower mounting plates 9 are connected between the front, rear, left, and right ends of the lower shell 1 and the discharge pipe 13 on the same side, and a smoke sensor 10 is mounted on one of the lower mounting plates 9;
[0022] The alarm assembly includes an antenna 4, an alarm light 5 and a pressure gauge 12. An upper mounting plate 3 is connected to the right side of the housing 1. The antenna 4 and the alarm light 5 are respectively mounted on the upper and lower sides of the upper mounting plate 3. The pressure gauge 12 is mounted on the housing 1. The antenna 4, the alarm light 5, the temperature sensor 7, the vacuum pump 8, the smoke sensor 10, the solenoid valve 15 and the pressure gauge 12 are all connected to the PLC controller 2 by signal.
[0023] When a fire occurs, the smoke sensor 10 can sense the smoke and transmit a signal to the PLC controller 2, and the PLC controller 2 can control the vacuum pump 8 and the temperature sensor 7 to start working and control the solenoid valve 15 to open. At this time, the vacuum pump 8 can suck the fire extinguishing material inside the shell 1 and spray it out in sequence through the connecting pipe 11, the discharge pipe 13 and the nozzle 14. At this time, the nozzles 14 on the front, back, left and right sides can spray the fire extinguishing material from the ceiling above to the front, back, left and right sides, thereby achieving the effect of increasing the fire extinguishing range and improving the efficiency of fire extinguishing;
[0024] While extinguishing the fire, the temperature sensor 7 can detect the temperature of the front, back, left and right sides of the housing 1 and transmit the signal to the PLC controller 2. The temperature sensor 7 corresponds to the solenoid valve 15 on the same side. The PLC controller 2 controls the solenoid valve 15 on the side with the highest temperature among the four temperature sensors 7 to increase the opening, and controls the opening of the remaining solenoid valves 15 to decrease, so that more fire extinguishing materials are sprayed out from the side with the highest temperature. The temperature at the location where the fire occurs is higher than that at other locations. Spraying more fire extinguishing materials on the side where the fire occurs can extinguish the fire more specifically, thereby improving the fire extinguishing effect. The arrangement of the temperature sensor 7 and the solenoid valve 15 can increase the fire extinguishing range while extinguishing the fire specifically, thereby effectively improving the fire extinguishing effect.
[0025] Since the pressure gauge 12 is installed on the shell 1, the pressure gauge 12 can detect the pressure of the fire extinguishing material in the shell 1. When there is no need to extinguish the fire, the pressure information detected by the pressure gauge 12 can be transmitted to the PLC controller 2. The PLC controller 2 controls the antenna 4 to transmit the pressure data. The staff only needs to carry a receiver corresponding to the antenna 4 to see the pressure inside the shell 1 on the receiver. There is no need to climb up to check the pressure on the pressure gauge 12, which is convenient for the staff to regularly check the storage amount of fire extinguishing materials in the suspended fire extinguisher to ensure safety. A minimum pressure is set inside the PLC controller 2. The pressure is the pressure when the storage amount of fire extinguishing materials in the shell 1 is insufficient to achieve the fire extinguishing effect. When the pressure gauge 12 detects the minimum pressure, the PLC controller 2 can control the alarm light 5 to light up and send a signal through the antenna 4. The staff can also receive the alarm information through the receiver, thereby achieving a better effect of monitoring the storage amount of fire extinguishing materials, ensuring that the staff can replenish the fire extinguishing materials more promptly when they are insufficient, thereby ensuring safety.
