Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire protection technology, specifically a multi-functional water testing device for fire protection testing. Background Technology
[0002] In the field of fire protection testing, fire sprinklers, as key components of building fire protection systems, directly determine the effectiveness of rescue efforts during fires due to their core performance characteristics such as water pressure stability and water output efficiency. Testing devices are crucial tools for ensuring the accuracy of fire sprinkler performance testing and are widely used in scenarios such as building fire protection engineering completion acceptance, routine maintenance, and periodic inspections. These devices need to work with sprinkler components to complete key processes such as water pressure testing and dynamic water output testing. They must also adapt to the testing needs of different building floors and sprinkler installation locations. Their ease of use, component storage safety, and rational water flow treatment directly affect the efficiency and standardization of the testing work.
[0003] Existing water testing devices have several shortcomings in practical applications: most devices lack a dedicated storage structure for the water testing nozzles, leaving them to be placed haphazardly after use. This not only makes them prone to collisions and contamination, leading to decreased detection accuracy or component damage, but also frequently results in nozzle loss, increasing testing costs. Furthermore, the devices lack convenient moving parts, and due to the dispersed nature of testing scenarios, relocation requires multiple people, which is particularly strenuous in high-rise buildings or confined spaces, significantly reducing testing efficiency. Additionally, the lack of targeted water flow guidance and recovery designs means that the water sprayed during testing flows directly onto the ground, wasting significant amounts of water and causing water accumulation and disorder at the testing site. This can potentially soak surrounding equipment, causing malfunctions, create slippery safety hazards, and increase the workload of subsequent site cleanup. Utility Model Content
