Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing agent storage technology, specifically a foam fire extinguishing agent anti-settling device. Background Technology

[0002] Foam extinguishing agents are highly susceptible to sedimentation during storage, which severely impacts their extinguishing performance. Traditional foam extinguishing agent storage devices lack effective anti-sedimentation measures, leading to stratification and sedimentation of the agent's components after prolonged periods of stillness. On one hand, this sedimentation results in uneven concentration distribution of the extinguishing agent, reducing its effectiveness in actual use and hindering timely and effective fire suppression, posing a significant threat to life and property safety. On the other hand, the accumulation of sediment can also clog pipes and valves in the storage device, affecting the normal discharge and delivery of the extinguishing agent, further reducing the reliability and practicality of the device. With increasingly stringent fire safety requirements, developing a device that effectively prevents foam extinguishing agent sedimentation has become crucial. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foam extinguishing agent anti-settling device, which solves the problem that existing foam extinguishing agents do not have anti-settling functions, affecting their subsequent use.

[0010] Beneficial effects

[0011] This invention provides a foam fire extinguishing agent anti-settling device, which has the following beneficial effects:

[0012] The first motor drives the main shaft to rotate, which in turn rotates the turntable and the rotating rod. The gear on the rotating rod meshes with the internal gear ring, causing the rotating rod to revolve around the main shaft while rotating on its own axis. The stirring blades and the spiral blades on the connecting rod work together to stir the foam extinguishing agent in the storage tank in all directions and at multiple angles, effectively preventing the extinguishing agent from settling, ensuring the uniform concentration of the extinguishing agent, and guaranteeing the extinguishing performance.

[0013] The locking assembly allows for easy insertion and removal of the locking pin via a lever, enabling quick disassembly and installation of the turntable and spindle. This facilitates maintenance and replacement of the turntable and rotating rod. The connecting rod is connected to the screw hole at the bottom of the rotating rod via a stud, making disassembly and installation convenient. Different specifications of connecting rods or helical blades can be replaced according to actual needs.

[0014] The lowering component is driven by a second motor to rotate the screw, which causes the lifting sleeve to move up and down along the screw, thereby raising and lowering the cover plate and the stirring component, making it convenient to remove the stirring component in a timely manner.
