Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting equipment, in particular to a quick spray-stopping tool for a fire-fighting sprinkler head. Background Art

[0002] The fire sprinkler system is an important part of building fire safety. Its main function is to suppress the spread of fire in time by spraying water when a fire occurs. However, the fire sprinkler head design that is widely used at present is reliable, but there are some problems under certain conditions. For example, when the sprinkler head is triggered and started, even if the fire has been extinguished, the sprinkler head will continue to spray water, resulting in unnecessary waste of water resources, and may cause further damage to the facilities and equipment inside the building. Especially in large commercial buildings or places with precision equipment, long-term spraying will cause immeasurable economic losses to the environment and equipment. In addition, if firefighters need to turn off the sprinkler head, they often have to manually close the main water valve of the entire fire protection system. This process can be time-consuming and may hinder the efficient implementation of rescue work.

[0003] In this context, the research and development of rapid spray stop technology is particularly important. The core function of the rapid spray stop device is to quickly shut down the spray of a single or local sprinkler head without relying on the main fire protection system, thereby reducing water waste and secondary damage to the environment and equipment. However, there is no widely used efficient rapid spray stop device on the market, and most design solutions have the following limitations:

[0004] First, the operability of existing spray-stopping technologies is low, especially in complex environments such as high temperature and smoke. Traditional manual mechanical spray-stopping devices may be difficult to quickly locate and operate. At the same time, these devices require high labor costs during use and require high professional skills from the operator.

[0005] Secondly, the existing devices have poor sealing performance, which may cause water to leak from the sprinkler head after the spraying stops, and cannot completely solve the problem of water resource waste and environmental damage. In addition, due to the complex design structure of these devices, their material cost and manufacturing cost are high, which limits their large-scale popularization and application in buildings.

[0006] In view of the above problems, the present invention proposes a fire sprinkler head quick spray stop tool, aiming to provide a quick spray stop solution with simple structure, convenient operation and reliable effect for the fire protection field. This tool adopts an innovative airbag design, which seals and wraps the sprinkler head by setting an airbag sleeve, and uses high-pressure gas to quickly expand the airbag, thereby achieving an efficient spray stop function. This design can not only effectively stop water spraying in a short time, but also ensure that the airbag fits tightly with the sprinkler head, eliminating water leakage problems.

[0007] The core components of this tool include the airbag cover, air pipe and gas cylinder. The airbag cover is made of high temperature and corrosion resistant nylon material, which can adapt to the high temperature and humidity conditions in the fire fighting environment. The air pipe is connected to the gas cylinder through threads, and symmetrical air holes are set at the bottom to ensure that the high-pressure gas can be quickly and evenly filled into the airbag. The gas cylinder is filled with high-pressure carbon dioxide gas, and the switching between inflation and sealing is achieved through the piston structure design, thereby greatly improving the reliability of the spray-stopping operation.

[0008] Compared with the traditional spray-stopping tool, the invention is innovative in the following aspects:

[0009] Rapid expansion and sealing: After the airbag is expanded by high-pressure gas, it can quickly fill all the gaps at the opening of the sprinkler head, thus forming a completely sealed closed space in a short time to prevent water spraying.

[0010] Ease of operation: This tool is designed with a connecting ring and cable tie, which can be quickly fixed on the sprinkler head without additional complicated operations, making it easy for firefighters to use in emergency situations.

[0011] Efficient and portable: The tool has a compact overall structure, light weight, and is easy to carry. It is suitable for use in various complex firefighting environments, especially in special scenarios such as large buildings or underground places.

[0012] Reusability: The airbag cover of the present invention is designed to be replaceable. After each use, it can be used again by simply replacing the cable tie, thereby reducing maintenance costs.

[0013] The application scenarios of this tool are not limited to emergency spray stopping at the fire scene, but can also be used for water flow blocking operation of a single sprinkler head during the maintenance of the sprinkler system, and has broad market application prospects. In the future, through further optimization of materials and gas filling technology, the device can also be upgraded to a fully automated rapid spray stopping system, further improving the intelligent level of fire fighting equipment.

[0014] In summary, the present invention proposes an innovative solution to the shortcomings of existing fire sprinkler head spray stopping technology, which not only effectively solves the problem of water resource waste, but also achieves significant breakthroughs in structural design, operational convenience and economic cost control. It is hoped that the widespread promotion of this tool will provide strong technical support for the fire protection industry and contribute to improving fire emergency response capabilities and reducing fire losses.

[0015] For this reason, we design a fire sprinkler head quick spray stop tool here. Summary of the invention
