Description

A rapid mixing and spraying device for a strap-on foam fire extinguishing system Technical Field

[0001] This utility model relates to the technical field of fire extinguishing equipment, specifically a rapid mixing and spraying device for a strap-on foam fire extinguishing system. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains a extinguishing agent and is used to extinguish fires. Fire extinguishers are common fire prevention facilities, stored in public places or areas where fires may occur. Foam fire extinguishers are a common type of fire-fighting equipment; however, current technology lacks devices for the portable transport and rapid deployment of foam fire extinguishers. Their extinguishing function is relatively limited, and they are inconvenient to use in conjunction with other extinguishing materials when held in hand. Therefore, those skilled in the art have proposed a rapid mixing and spraying device for a shoulder-mounted foam fire extinguishing system to address the problems mentioned in the background. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid mixing and spraying device for a strap-on foam fire extinguishing system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rapid mixing and spraying device for a strap-on foam fire extinguishing system includes a back box. Straps are provided on both sides of the front end of the back box. A door is installed on one outer wall of the back box, and a socket and control panel are installed on the other outer wall. A controller is installed on the inner wall of the back box. A nozzle is inserted into the socket. A dry powder box is installed at the bottom of the back box. A placement seat and an arc-shaped tube are respectively provided in the middle and upper parts of the inner cavity of the back box near the door. A foam fire extinguisher is installed on the placement seat, and one end of the arc-shaped tube is connected to the foam fire extinguisher via a connecting sleeve. The outlet end of the device is connected. A telescopic component is provided on the inner top surface of the back box at the position corresponding to the switch of the foam fire extinguisher. The side of the arc-shaped tube is connected to one end of the mixing tube. An air pump is installed on the dry powder box. The air pump is connected to the other end of the mixing tube. The other end of the arc-shaped tube is connected to the hose. Several recovery components are provided on the other side of the inner cavity of the back box. The middle part of the hose is coiled around the recovery components. The other end of the hose is inserted outside the back box and connected to the nozzle. The telescopic component, air pump, and control panel are all connected to the controller circuit.

[0006] As a further embodiment of this utility model: the recycling component comprises a fixed plate, a U-shaped frame, an elastic element, a movable shaft, and a roller. The fixed plate is fixedly installed inside the box. Two U-shaped frames are symmetrically spaced on the fixed plate. A movable shaft is fitted inside the U-shaped frame. A roller is sleeved in the middle of the movable shaft. The elastic element is installed inside the U-shaped frame. The lower ends of the left and right parts of the movable shaft are connected to one end of the elastic element, and the other end of the elastic element is connected to the fixed plate.

[0007] As a further improvement of this utility model: the recycling components are configured as two that are distributed vertically about the inner cavity of the box, and the two recycling components are arranged opposite to each other.

[0008] As a further improvement of this utility model, a guide wheel is provided on one side of the inner cavity of the back box near the socket.

[0009] As a further embodiment of this utility model: a vertical plate is connected to the top of the placement seat on the side away from the box door, and a reinforcing ring is detachably installed on the top of the vertical plate by bolts, and the middle part of the foam fire extinguisher is fixed inside the reinforcing ring.

[0010] The present invention has the following advantages: the device is convenient to carry foam fire extinguishers and dry powder boxes by setting a back box and carrying straps, and the hose can be returned to the back box after being pulled out with the nozzle by setting a recovery component. The combination of the arc-shaped tube and the mixing tube allows the foam fire extinguisher and the dry powder box to be used together, thereby mixing and spraying the foam and dry powder to improve the fire extinguishing effect. The overall device has a simple structure and is easy to operate, and is easy to carry and use. Attached Figure Description

A placement seat 21 and an arc-shaped tube 8 are respectively provided in the middle and upper parts of the inner cavity of the back box 1 near the door 16. A foam fire extinguisher 22 is installed on the placement seat 21. The arc-shaped tube 8... One end is connected to the outlet end of the foam fire extinguisher 22 via the docking sleeve 20. A telescopic component 23 is provided on the inner top surface of the back box 1 at the position corresponding to the switch of the foam fire extinguisher 22. The side of the arc-shaped tube 8 is connected to one end of the mixing tube 19. An air pump 18 is installed on the dry powder box 17. The air pump 18 is connected to the other end of the mixing tube 19. The other end of the arc-shaped tube 8 is connected to the hose 9. Several recovery components 10 are provided on the other side of the inner cavity of the back box 1. The middle part of the hose 9 is coiled around the recovery component 10. The other end of the hose 9 is inserted to the outside of the back box 1 and connected to the nozzle 3. The telescopic component 23, the air pump 18, and the operation panel 4 are all connected to the controller 7.

[0021] Please refer to Figures 2 and 3. The recycling assembly 10 comprises a fixed plate 11, a U-shaped frame 12, an elastic element 13, a movable shaft 14, and a roller 15. The fixed plate 11 is fixedly installed inside the box. Two U-shaped frames 12 are symmetrically spaced on the fixed plate 11. The movable shaft 14 is fitted inside the U-shaped frame 12. The roller 15 is sleeved in the middle of the movable shaft 14. The elastic element 13 is installed inside the U-shaped frame 12. The lower left and right ends of the movable shaft 14 are connected to one end of the elastic element 13. The other end of the elastic element 13 is connected to the fixed plate 11. In this embodiment, the recycling assembly 10 is configured as two components distributed vertically about the inner cavity of the box. The two recycling assemblies 10 are arranged opposite each other. A guide wheel 26 is provided on one side of the inner cavity of the back box 1 near the socket 5.

[0022] Example 2: Referring to Figure 2, based on Example 1, a vertical plate 24 is connected to the top of the placement seat 21 on the side away from the box door 16. A reinforcing ring 25 is detachably installed on the top of the vertical plate 24 by bolts. The middle part of the foam fire extinguisher 22 is fixed in the reinforcing ring 25.

[0024] Working principle: When in use, the user carries the case 1 on the back via the shoulder strap 2 and holds the nozzle 3 by hand. The control panel 4 can be set in a convenient position. The control panel 4 controls the telescopic component 23 and the air pump to start. The telescopic component 23 extends and presses the switch of the foam fire extinguisher 22. The foam fire extinguisher 22 sprays foam into the arc-shaped tube 8. The air pump and the mixing tube 19 work together to transport the dry powder in the dry powder box 17 into the arc-shaped tube 8, realizing the mixing of foam and dry powder. When the hose 9 is pulled out, the hose 9 squeezes the roller 15. The roller 15 drives the movable shaft 14 to squeeze the elastic component 13. The elastic component 13 can reset when the hose 9 is not under tension, thereby realizing the recovery of the hose 9. The mixed foam and dry powder are transported to the nozzle 3 through the hose 9 and sprayed out. The user holds the nozzle 3 and adjusts the spray position for efficient fire extinguishing.
