Description

Technical Field

[0001] This utility model relates to the field of wheeled fire extinguishing technology, specifically to the structure of a cold-resistant wheeled water-based fire extinguishing device. Background Technology

[0002] Water-based fire extinguishers can extinguish initial fires involving flammable solids, flammable oils, flammable gases, and electrical equipment with voltages below 1,000 volts. Their extinguishing effect is significantly better than that of dry powder fire extinguishers. They also feature high extinguishing efficiency, strong resistance to reignition, no secondary pollution, and are non-toxic and non-irritating. Furthermore, they are 100% biodegradable, making them an ideal fire protection product.

[0003] For example, patent document CN 217526207 U discloses a cold-resistant water-based fire extinguishing agent device, including: a trolley frame, on one side of which a support frame for anti-slip is fixedly installed, and on the other side of the trolley frame are rollers, with two rollers symmetrically distributed on both sides of the trolley frame. A drive shaft is fixedly connected to the axis of the rollers, and the drive shaft is rotatably embedded in the side wall of the trolley frame; it also includes: a shell, which is fixedly connected to the upper surface of the trolley frame. The shell is vertically arranged, and a fire extinguishing agent storage tank is fitted to the inner side of the shell. A coaxially arranged docking ring is fixedly connected to the bottom surface of the fire extinguishing agent storage tank. This cold-resistant water-based fire extinguishing agent device is equipped with an active heating structure and a corresponding heat preservation structure, which effectively improves the cold resistance of the device to prevent the liquid fire extinguishing agent inside the device from solidifying in a cold environment, and is equipped with a large-capacity fire extinguishing agent storage tank that is easy to disassemble and assemble.

[0004] However, when this structure is used for actual fire extinguishing, due to its own structural limitations, the extinguishing agent inside cannot be heated more evenly and with cold resistance. Furthermore, when the extinguishing agent is sprayed out of the nozzle, it cannot be heated to a better cold-resistant temperature. At the same time, the equipment cannot be quickly supported and protected as a whole, which cannot meet the needs of daily use. Therefore, it is urgent to design a cold-resistant wheeled water-based fire extinguishing device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for a cold-resistant wheeled water-based fire extinguishing device, in order to solve the problems mentioned in the background art. Due to the limitations of its own structure, the existing structure cannot achieve a more thorough and uniform cold-resistant heating of the extinguishing agent during actual fire extinguishing use. Furthermore, the extinguishing agent cannot be heated to a better cold-resistant temperature when sprayed out of the nozzle. At the same time, the device cannot provide rapid support and protection for the entire device, thus failing to meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structure of a cold-resistant wheeled water-based fire extinguishing device, including a storage cylinder, a top connector fixedly connected to the top of the storage cylinder, a bottom connector fixedly connected to the bottom of the storage cylinder, a liquid control seat provided on the surface of the top connector, a liquid pump frame provided at the top of the liquid control seat, and a heating unit provided at the bottom of the liquid control seat;

[0007] A support base is provided, with the bottom end of the base fixedly connected to the support base and the back frame fixedly connected to the back of the support base.

[0008] Preferably, the surface of the back frame is provided with a movable shaft, and an adjustment rod is fixedly connected to the surface of the movable shaft.

[0009] Preferably, both the back frame and the support base are provided with movable rollers at their bottom ends, a support airbag is provided between the movable rollers, and a support plate is provided at the bottom end of the support airbag.

[0010] Preferably, a spiral stirring roller is provided at the center of the storage cylinder, and a first heating pad is provided on the inner wall of the storage cylinder.

[0011] Preferably, the storage cylinder is provided with a side heating frame on all four sides, and the inner wall of the side heating frame is provided with a side infusion tube.

[0012] Preferably, a heating valve head is fixedly connected to the surface of the liquid control seat, and a second heating pad is provided on the inner wall of the heating valve head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The structure of this cold-resistant wheeled water-based fire extinguishing device, through its storage cylinder, top connector, bottom connector, control valve seat, pump rack, heating unit, spiral roller, first heating pad, side heating rack, side delivery pipe, heating valve head, and second heating pad, allows for more efficient dual heating of the extinguishing agent. In actual use, the operator first fills the storage cylinder with the required extinguishing agent, then controls the pump rack on the control valve seat to draw in the extinguishing agent. The heating unit at the bottom of the control valve seat further enhances the heating efficiency of the extinguishing agent through a second heating pad within the heating valve head. The heating pads at the inner wall of the storage cylinder and the first heating pad at the inner wall of the storage cylinder are designed to provide cold-resistant heating for the extinguishing agent inside the storage cylinder. The second heating pad inside the heating valve head provides targeted heating for the extinguishing agent during spraying, thus improving the cold-resistant effect of the extinguishing agent and enhancing the extinguishing effect. At the same time, the spiral stirring roller inside the storage cylinder is activated daily to continuously deliver the extinguishing agent to the bottom of the storage cylinder. The bottom of the storage cylinder then delivers the extinguishing agent upwards from the four side liquid infusion pipes on the inner wall of the storage cylinder. This, combined with the side heating frame, ensures uniform heating of the extinguishing agent inside the side liquid infusion pipes, thereby guaranteeing the uniformity of the cold-resistant heating of the extinguishing agent inside the storage cylinder and demonstrating the practicality of the equipment design.

[0015] The structure of this cold-resistant trolley-type water-based fire extinguishing device, through the inclusion of a storage cylinder, support base, back frame, movable shaft, control rod, casters, support airbag, and support plate, further enhances the overall usability of the equipment. During daily use, operators can move the entire device using the casters at the bottom of the support base and back frame. The movable shaft and control rod on the back frame surface are used for overall movement control. When the device reaches the designated location, the support airbag at the bottom of the support base can be activated, inflating it to fit the support plate at the bottom onto the ground, thus completing the support and fixation operation for the entire water-based fire extinguishing device during firefighting use. This demonstrates the comprehensiveness of the equipment design. Attached Figure Description

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A cold-resistant wheeled water-based fire extinguishing device includes a storage cylinder 1, a top connector 2 fixedly connected to the top of the storage cylinder 1, a bottom connector 3 fixedly connected to the bottom of the storage cylinder 1, a liquid control seat 4 provided on the surface of the top connector 2, a liquid pump frame 5 provided at the top of the liquid control seat 4, a heating unit 6 provided at the bottom of the liquid control seat 4, a spiral stirring roller 14 provided at the center of the inside of the storage cylinder 1, a first heating pad 15 provided on the inner wall of the storage cylinder 1, and side heating frames 16 provided on the four sides of the storage cylinder 1. The inner walls of the side heating frames 16 are provided with... There is a side infusion tube 17, and a heating valve head 18 is fixedly connected to the surface of the liquid control seat 4. The inner wall of the heating valve head 18 is provided with a second heating pad 19. When the spiral stirring roller 14 inside the storage cylinder 1 is activated, the extinguishing agent can be continuously conveyed to the bottom of the storage cylinder 1. The bottom of the storage cylinder 1 then conveys the extinguishing agent upward from the four sides of the inner wall of the storage cylinder 1 through the side infusion tube 17. With the cooperation of the side heating frame 16, the extinguishing agent inside the side infusion tube 17 is uniformly heated, thereby ensuring the uniformity of heating and cold resistance of the extinguishing agent inside the storage cylinder 1.

[0024] The support base 7 is fixedly connected to the bottom end of the bottom base 3. The back frame 8 is fixedly connected to the back of the support base 7. The surface of the back frame 8 is provided with a movable shaft 9. The surface of the movable shaft 9 is fixedly connected with an adjustment rod 10. The bottom ends of the back frame 8 and the support base 7 are both provided with movable rollers 11. A support airbag 12 is provided between the movable rollers 11. The bottom end of the support airbag 12 is provided with a support plate 13. The overall movement control operation is performed through the movable shaft 9 and the adjustment rod 10 on the surface of the back frame 8. At the same time, when the equipment reaches the designated position, the support airbag 12 at the bottom of the support base 7 can be activated to inflate it and fit the support plate 13 at the bottom end onto the ground.

[0025] Working Principle: During use, the operator first fills the storage cylinder 1 with the extinguishing agent to be used. Then, the pump frame 5 on the surface of the control seat 4 controls the suction of the extinguishing agent. The extinguishing agent is then used. The heating unit 6 at the bottom of the control seat 4 heats the extinguishing agent at the second heating pad 19 inside the heating valve head 18 and the first heating pad 15 on the inner wall of the storage cylinder 1. The first heating pad 15 provides cold-resistant heating to the extinguishing agent inside the storage cylinder 1, while the second heating pad 19 inside the heating valve head 18 provides targeted heating during spraying, further improving the cold-resistant effect and extinguishing efficiency. Simultaneously, the spiral roller 14 inside the storage cylinder 1 is activated regularly to continuously deliver the extinguishing agent to the bottom of the storage cylinder 1. The extinguishing agent is then transported upwards from the four sides of the inner wall of the storage cylinder 1 through the inner inlet tubes 17. This, combined with the side heating frame 16, ensures uniform heating of the extinguishing agent inside the inner inlet tubes 17, thus guaranteeing the uniformity of heating and cold resistance of the extinguishing agent inside the storage cylinder 1. During daily use, the equipment can be moved by the support base 7 and the movable rollers 11 at the bottom of the back frame 8. The overall movement is controlled by the movable shaft 9 and the control rod 10 on the surface of the back frame 8. When the equipment reaches the designated position, the support airbag 12 at the bottom of the support base 7 can be activated to inflate it and fit the support plate 13 at the bottom onto the ground, thus completing the support and fixation operation of the water-based fire extinguishing device during overall fire extinguishing. The above is the complete working principle of this utility model.
