Description

Technical Field

[0001] This utility model relates to the field of anti-clogging nozzle technology, and in particular to an anti-clogging nozzle for a fire extinguishing device. Background Technology

[0002] In modern fire safety systems, fire extinguishing devices are key equipment for combating fires and are widely used in industrial plants, commercial buildings, transportation, and many other fields. Whether it is an automatic sprinkler system, a dry powder extinguishing device, or a foam extinguishing device, the nozzle, as the terminal component for spraying the extinguishing agent, directly determines the extinguishing efficiency and effect. However, in actual use, nozzle clogging is a frequent problem, seriously affecting the reliability and effectiveness of fire extinguishing devices and becoming a key bottleneck restricting the improvement of fire safety levels. At the same time, with the continuous improvement of fire safety requirements and the trend of intelligent and automated development of fire extinguishing devices, the development of a highly efficient and reliable anti-clogging nozzle to solve the clogging problem of traditional nozzles has become an urgent need to improve the performance of fire extinguishing devices and ensure public safety.

[0003] Currently, anti-clogging nozzles for fire extinguishing devices on the market mainly consist of a main shell and a variable-diameter flow channel. Traditional fire extinguishing nozzles mostly adopt a single-aperture straight-cylinder design. This structure is highly prone to clogging when dealing with complex extinguishing agents. Extinguishing agents inevitably contain suspended particles and impurities. For example, dry powder extinguishing agents may be mixed with incompletely crushed particles and packaging debris from raw materials during production, transportation, and storage. Water-based extinguishing agents may also contain silt from water and rust from pipe corrosion, gradually leading to clogging. Although some technologies have been developed to address nozzle clogging issues... Solutions include regular manual cleaning and using filters to remove impurities from the extinguishing agent. Anti-clogging nozzles in the system often use complex threaded flange connections to fix them to the fire extinguishing piping system. Threaded connections require operators to precisely align the threads and tighten them by multiple turns, which is not only time-consuming but also extremely inconvenient in confined spaces. Slight carelessness can also lead to stripped threads, affecting installation quality and sealing. Flange connections require multiple bolts for fixing, necessitating precise alignment of the flange before installation and tightening of each bolt individually with a wrench during installation. The entire process is cumbersome and time-consuming, severely reducing installation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-clogging nozzle for a fire extinguishing device, aiming to improve the problem that traditional anti-clogging nozzles in the prior art are not easy to install quickly.

A fixed block is slidably connected to the outer wall of the sliding plate, and fixed sleeves are fixedly connected to the front and rear sides of the bottom of the inner wall of the fixed block. A locking shaft is slidably connected to the inner wall of the fixed sleeve, and a spring is fixedly connected to the top of the outer wall of the locking shaft. The other end of the spring is fixed to the inner wall of the fixed sleeve. A locking groove is provided on the outer wall of the sliding plate, and the top of the outer walls of multiple locking shafts engages with the corresponding locking grooves. An anti-clogging mechanism is provided at the bottom of the fixed circular plate, which is used to prevent the fire extinguishing device from being blocked.

[0006] As a further description of the above technical solution:

[0007] The anti-clogging mechanism includes water outlet pipes.

A fan blade is fixedly connected to the outer wall of the rotating shaft near the top. Connecting pipes are fixedly connected to the outer walls of the liquid storage pipes near the center. A spray nozzle is fixedly connected to the bottom of the connecting pipe. The other end of the multiple connecting pipes is in contact with the outer wall of the spray nozzle.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the fixed circular plate is fixedly connected with a flexible strip on all four sides, and the top of the fixed circular plate is fixedly connected with a liquid inlet.

[0010] As a further description of the above technical solution:

[0021] 1. In this utility model, fixing plates two are fixed on the left and right sides of the outer wall of the fixing circular plate, and springs one are fixed on the inner wall of the fixing plates two. The elastic action of the springs one allows the sliding plate to move within the inner wall of the fixing block.

A fixing plate is fixed to the inner wall of the water outlet pipe near the bottom. The inner wall of the fixing plate is rotatably connected to a rotating shaft. When water is sprayed downward from the inner wall of the water outlet pipe, the water flow will drive the fan blades, so that multiple fan blades can drive the rotating shaft to rotate. Multiple connecting pipes are fixed to the outer wall of the liquid storage pipe. After the water flow rotates on the inner wall of the liquid storage pipe, it can drive the water flow downward, so that it is sprayed downward from the inner wall of the spray nozzle, thus achieving the function of preventing internal blockage.
