Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguishing, in particular to a non-pressure storage type superfine dry powder fire extinguishing device. Background Art

[0002] The non-pressurized ultra-fine dry powder fire extinguishing device is a modern fire extinguishing equipment that uses special technology to process the dry powder fire extinguishing agent into ultra-fine particles to improve the efficiency and speed of fire extinguishing. Unlike the traditional pressurized dry powder fire extinguishing device, this device does not pre-compress and store the dry powder fire extinguishing agent before use. Instead, when the device is started, the dry powder is quickly delivered to the fire extinguishing area through an external power source (such as electric, pneumatic or mechanical drive, etc.);

[0003] In some current non-pressurized ultra-fine dry powder fire extinguishing devices, the device cannot be pressurized quickly during use, resulting in the inability to extinguish the fire in time. Utility Model Content

[0004] The utility model aims to provide a non-pressure storage type ultra-fine dry powder fire extinguishing device, which can quickly store pressure and prevent the device from being quickly pressurized during use, thereby causing failure to extinguish the fire in time.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model discloses a non-pressure storage type ultrafine dry powder fire extinguishing device, comprising a fire extinguishing tank, wherein the top of the fire extinguishing tank is fixedly connected with a controller, a side of the fire extinguishing tank close to the controller is fixedly connected with a fixing frame, an inner wall of an end of the fixing frame away from the fire extinguishing tank is fixedly connected with a motor, an output end of the motor is fixedly connected with a turntable, a side of the turntable away from the motor is fixedly connected with a rotator, an outer wall of the rotator is rotatably connected with a push rod, an end of the push rod away from the rotator is rotatably connected with a piston rod, an end of the piston rod away from the push rod penetrates the top of the fire extinguishing tank and extends to the inside, and such an arrangement is for pressurizing by piston movement.

[0007] Furthermore, the controller is provided with a display screen, the controller is provided with control buttons, and the rotator is located at the edge of the turntable.

[0008] Furthermore, one end of the piston rod away from the push rod is fixedly connected to a piston head, and the piston head is slidably connected to the inner wall of the fire extinguisher tank. An air inlet pipe is connected to the fire extinguisher tank, and an air outlet pipe is fixedly connected to the inner wall of the fire extinguisher tank. A one-way air valve is provided on the air outlet pipe. This arrangement is to ensure the air pressure below the one-way air valve.

[0009] Furthermore, the diameter of the piston head is the same as the inner diameter of the fire extinguisher, and the air outlet pipe is located below the air inlet pipe.

[0010] Furthermore, an air pressure monitor is fixedly connected to the inner wall of the air outlet pipe, a pressure relief pipe is fixedly connected to the inner wall of the fire extinguisher tank, a solenoid valve is arranged on the pressure relief pipe, a dry powder adding pipe is connected to the fire extinguisher tank, and a fire extinguishing pipe is arranged on the fire extinguisher tank. This arrangement is for the convenience of opening the pressure relief pipe through the solenoid valve.

[0011] Furthermore, the pressure relief pipe is located below the air outlet pipe, the air pressure monitor is located between the air outlet pipe and the pressure relief pipe, a valve is provided on the dry powder adding pipe, and a valve is provided on the fire extinguishing pipe.

[0012] The utility model has the following beneficial effects:

[0013] 1. The non-pressure storage type ultra-fine dry powder fire extinguishing device drives the turntable to rotate by a motor. The rotation of the turntable drives the rotator to rotate, so that the rotator pulls the push rod to move, so that the length of the push rod in the vertical direction changes, thereby pulling the piston rod to move back and forth, and the piston rod pushes the piston head to move back and forth. When the air intake pipe moves to the top of the air intake pipe, the outside air will enter the fire extinguishing tank through the air intake pipe. When the air intake pipe moves to the bottom of the air intake pipe, the air intake pipe continues to move downward, and the air above the air outlet pipe will enter the bottom through the air outlet pipe. The one-way air valve can prevent air backflow, so that the air pressure below the air outlet pipe increases, thereby achieving the purpose of pressure storage.

[0014] 2. When the non-pressure storage type ultra-fine dry powder fire extinguishing device is in use, the air pressure below the air outlet pipe will be monitored by the air pressure monitor and fed back to the display screen of the controller to prevent the dry powder from being unable to be blown out due to insufficient air pressure. When the air pressure can make the dry powder spray out evenly, open the valve on the fire extinguishing pipe, and open the solenoid valve on the pressure relief pipe through the button on the controller. At this time, the air above the pressure relief pipe will flow through the pressure relief pipe at a faster speed, thereby blowing out the dry powder.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
