Intelligent spray nozzle based on gas inspection

Abstract

The invention provides an intelligent spray nozzle based on gas inspection. Compared with conventional spray nozzles, a detection control apparatus, a sliding switch apparatus and an opening / closing apparatus and the like devices are added, and an air outlet hole is formed in the side part of the spray nozzle, so that when a glass sphere is expanded, a sealing pad is pulled and drives the sliding switch apparatus, which then slides down to cover the air outlet hole, and water flow is sprayed smoothly during spraying. When gas inspection is required, the sliding switch apparatus keeps the air outlet hole opened, so that the air inspection is successfully carried out. The intelligent spray nozzle achieves intelligent switching between spraying and gas, is low in detection cost and work load, can be started at any time and has no demand and influence on work environment.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to an intelligent sprinkler head based on gas detection. Background technique [0002] Fire is one of the frequent disasters that seriously threaten human survival and development in the world today. The occurrence frequency of fire is high, and the span of time and space is large. Once it occurs, the economic loss and casualties caused are incalculable. The fire sprinkler system of a building is an important fire-fighting facility. At the same time, its role in fire prevention determines that the number of times the fire sprinkler system is used is very small, and it has not even worked once in decades, but it must be ensured that it is activated when necessary can work normally and reliably. Long-term water injection in the sprinkler pipe of the wet fire sprinkler system is prone to rust and moss growth, resulting in blockage of the sprinkler pipe; and the sprinkler pipe of ...

AI Technical Summary

Problems solved by technology

[0004] There has always been a problem in the field of fire protection facilities. The cost of on-site inspection of fire sprinklers on the floor is very high. If the water is sprayed out, it will greatly affect the working environment where the sprinklers are located, such as in the office. On-site water spray testing in the middle of the day will wet the documents and computers in the office

If the items in the office are removed and inspected, the cost of each inspection will be very high. If no water is sprayed, it is difficult to know whether the sprinkler pipes in the sprinkler system are damaged, and it is necessary to determine which part is damaged. , which requires corresponding detection of the sprinkler equipment, but the existing technology is to make improvements in the sprinkler head and the sprinkler pipeline, and the improvement that can be made for the gas detection in the sprinkler head is very limited. At present, there is no smart sprinkler head that cuts the gas detection outlet on the sprinkler head

[0005] Traditional fire-fighting facilities cannot be automatically monitored by networking, and do not have the ability to fine-tune real-time monitoring. The cost of manual inspection of fire sprinkler systems is high and the procedures are cumbersome, and high-frequency inspections cannot be performed.

At the same time, since the sprinkler heads in the current sprinkler system are not numbered, fine management of the sprinkler heads cannot be carried out, and there is no way for the sprinkler heads to be automatically networked and recorded after the inspection is completed.

[0006] The wet fire sprinkler system is filled with water for a long time, which is prone to rust and moss growth, while the dry fire sprinkler system is easy to mix foreign objects, or crawl into small animals, or be corroded by moisture in the air. If an accident occurs, it is easy to cause fire. The equipment cannot function normally and realize the fire extinguishing function

If the fire protection system is equipped with electronic devices and powered by mains power, it is necessary to add power connections at each detection point, which is costly and prone to accidents. At the same time, it relies on mains power supply and cannot be detected in the event of a power outage. If dry batteries are used For power supply, on the one hand, the dry battery has limited capacity and is prone to leakage, which reduces the reliability of the system. On the other hand, when the system fails, it is impossible to judge whether it is due to the exhaustion of the dry battery or the system itself.
