Description

Technical Field

[0001] The present application relates to the technical field of fire-fighting equipment, and in particular to a foam fire-fighting equipment for power plants. Background Art

[0002] With the promulgation and implementation of my country's Fire Protection Law, fire awareness is growing across all sectors of society. Sustained socioeconomic development has led to a continuous increase in the number of locations requiring fire protection, resulting in a growing and increasing demand for fire protection products. In power plants, in particular, foam firefighting equipment is primarily used to extinguish fires in areas such as oil tanks, transformers, fuel-fired boiler rooms, and fuel-fired generator rooms.

[0003] Currently, foam firefighting equipment used in foam firefighting falls into two main categories: fixed foam firefighting systems and small-scale firefighting devices such as portable fire extinguishers. In practical use, each type of equipment presents its own set of challenges. Fixed foam firefighting systems have complex and bulky supporting equipment, making operation cumbersome and inflexible. Meanwhile, small-scale firefighting devices such as portable fire extinguishers have small volumes, limited extinguishing agents, and can only be used for a few seconds, making them less effective in extinguishing fires.

[0004] In response to the above problems, the inventors have proposed a new type of foam fire-fighting equipment for power plants, aiming to address the shortcomings of existing equipment and provide a more efficient and flexible fire-fighting solution. Summary of the Invention

[0005] In response to the above problems, the present application provides a foam fire-fighting equipment for power plants, which uses a vehicle to flexibly transport the fire-fighting device, and adjusts the spray direction of the water mist nozzle through an operating lever and a universal joint to accurately extinguish the fire; the nozzle height can also be adjusted, thereby improving practicality.

[0030] Example 1

[0031] Figure 1-3 The present invention provides a foam fire-fighting device for a power plant, including a carrier 1 and a fire-extinguishing device 2. The carrier 1 includes a base plate 11, universal wheels 12, a push rod 13, and a wall plate 14. The fire-extinguishing device 2 includes a tank 21, a nitrogen starter bottle assembly 22, an air inlet valve 24, a discharge valve 25, and a water mist nozzle 27.

[0032] The tank body 21 is detachably mounted on the upper surface of the base plate 11;

[0033] A discharge valve 25 is fixedly mounted on the tank body 21, a feed pipe 26 is fixedly mounted on the discharge valve 25, and the other end of the feed pipe 26 is fixedly connected to and communicated with a water mist nozzle 27;

[0034] A fixed rod 5 is fixedly mounted on one end of the upper surface of the bottom plate 11, a sliding rod 6 is slidably mounted in the fixed rod 5, a universal joint 7 is rotatably mounted on the top end of the sliding rod 6, and a water mist nozzle 27 is hingedly mounted in the universal joint 7;

[0035] An operating rod 9 is fixed to the water mist nozzle 27, and a driving assembly 10 is installed in the bottom end of the fixed rod 5;

[0036] Specifically, the fire extinguishing device 2 is a foam fire-fighting device, and the tank 21 is filled with a synthetic foam fire extinguishing agent. By mounting the fire extinguishing device 2 on the carrier 1, the fire extinguishing device 2 can be flexibly transported using the carrier 1 according to actual conditions. Furthermore, the driving assembly 10 can be used to drive the sliding rod 6 to slide and rise within the fixed rod 5 according to the height of the fire point, thereby adjusting the water mist nozzle 27 to an appropriate height.

[0037] Specifically, the material delivery pipe 26 is a high-pressure telescopic hose.

[0038] In one possible embodiment, the driving assembly 10 includes a worm 102 , and the worm 102 is rotatably mounted in the top end of the fixed rod 5 , and a turning handle 101 is fixedly mounted on one end of the worm 102 ;

[0039] A worm gear 103 is rotatably mounted in the bottom end of the fixed rod 5 , and the worm gear 103 is meshed with the worm 102 ;

[0040] A threaded rod 104 is fixedly mounted on the upper surface of the worm wheel 103, and the threaded rod 104 is threadedly inserted into the sliding rod 6;

[0041] By adopting the above technical solution, the handle 101 is used to drive the worm 102 to rotate, so that the worm 102 drives the worm wheel 103 to rotate, and then drives the threaded rod 104 to rotate. Finally, the threaded rod 104 drives the sliding rod 6 to slide and rise in the fixed rod 5.

[0042] In a possible embodiment, a limit buckle 8 is fixedly mounted on the top of the wall plate 14, and the operating rod 9 can be clamped in the limit buckle 8;

[0043] By adopting the above technical solution, when the device is not in use, the operating rod 9 can be clamped in the limit buckle 8 to limit the operating rod 9 and the water mist nozzle 27 to prevent the water mist nozzle 27 and the operating rod 9 from swinging;

[0044] Since the water mist nozzle 27 is heavier than the operating rod 9 , the water mist nozzle 27 will press the operating rod 9 when there is no external force, so that the operating rod 9 is stuck in the limit buckle 8 .

[0045] In one possible embodiment, two symmetrically distributed bases 3 are fixedly mounted on the upper surface of the bottom plate 11, and straps 4 are detachably mounted on both bases 3, and the tank body 21 can be detachably mounted on the bases 3 via the straps 4;

[0046] By adopting the above technical solution, the tank body 21 is detachably mounted on the base 3 using the strap 4 , making it easy to replace and disassemble the tank body 21 .

[0047] In one possible embodiment, an air inlet valve 24 is fixedly mounted on one end of the tank body 21, an air delivery pipe 23 is fixedly mounted on the top of the nitrogen starting bottle assembly 22, and the other end of the air delivery pipe 23 is fixedly connected to and communicates with the air inlet valve 24;

[0048] By adopting the above technical solution, the air inlet valve 24 is opened to allow the high-pressure nitrogen in the nitrogen starter bottle group 22 to pass through the air pipe 23 to drive the foam fire extinguishing agent in the tank body 21 to be sprayed out from the water mist nozzle 27;

[0049] Specifically, the air inlet valve 24 and the discharge valve 25 are both one-way valves.

[0050] In a possible embodiment, a wall plate 14 is fixedly mounted on one end of the bottom plate 11, a push rod 13 is fixedly mounted on one side of the wall plate 14, and universal wheels 12 are rotatably mounted at the four corners of the lower surface of the bottom plate 11;

[0051] By adopting the above technical solution, the push rod 13 and the universal wheel 12 are used to move the vehicle 1 and the fire extinguishing device 2.

[0052] The working principle of this utility model is as follows:

[0053] When in use, the fire extinguishing device 2 can be flexibly transported using the carrier 1 according to actual conditions. Furthermore, the height of the water mist nozzle 27 can be adjusted according to the height of the fire point by following the steps below: the handle 101 is used to rotate the worm 102, which in turn rotates the worm 102, which in turn rotates the worm gear 103, which in turn rotates the threaded rod 104, which in turn drives the sliding rod 6 to slide and rise within the fixed rod 5, thereby adjusting the water mist nozzle 27 to a suitable height.

[0054] Next, the air inlet valve 24 and the discharge valve 25 are opened, and the high-pressure nitrogen in the nitrogen priming cylinder assembly 22 drives the foam fire extinguishing agent in the tank 21 to be sprayed out from the water mist nozzle 27. At the same time, the spray direction of the water mist nozzle 27 is adjusted by operating the operating lever 9 through the universal joint 7, so that the foam fire extinguishing agent is sprayed precisely at the fire point, thus achieving the purpose of flexible operation and precise fire extinguishing.

[0055] The above embodiments are intended only to illustrate the technical solutions of the present application and are not intended to limit them. The present application is not limited to the precise structures described above and illustrated in the accompanying drawings, and it cannot be assumed that the specific implementation of the present application is limited to these descriptions. For those skilled in the art of the present application, any changes and modifications made without departing from the concept of the present application should be deemed to fall within the scope of protection of the present application.
