Description

Technical Field

[0001] The utility model relates to the technical field of foam fire extinguishing agent storage, in particular to a warehouse for storing foam fire extinguishing agent. Background Art

[0002] Foam fire extinguishing agents are water-miscible and produce foam through physical and chemical reactions. There are many types of foam fire extinguishing agents, each with varying properties and usage methods. Based on their composition, they can be categorized as aqueous film-forming foam (AFFF), fluoroprotein foam (FP), protein foam (P), and synthetic foam (S). Currently, aqueous film-forming and synthetic foams are the most commonly used. Foam fire extinguishing agents are one of the most effective fire extinguishing agents for extinguishing liquid fires because they form a coagulated, floating layer of foam on the surface of liquids, acting as a suffocating and cooling agent. Chemical plant fires are often associated with flammability, explosiveness, corrosiveness, toxicity, and leakability. Foam fire extinguishing agents are the most commonly used fire extinguishing material in chemical plants, so their storage capacity is crucial for the rapid control of chemical fires. In order to respond to and prevent chemical plant fires in a timely and effective manner, fire rescue stations are usually set up in large chemical plant production areas or chemical plant clusters to respond to the occurrence of corresponding fires. The fire rescue stations will be equipped with corresponding fire rescue equipment and foam fire extinguishing agents according to the type of fire that may occur, in case of emergency. When a fire occurs, the designated fire extinguishing agent can be quickly filled or replaced in the fire truck. However, due to its extremely easy foaming property, the mixing of air during filling or replacement will cause foaming. Since the foam liquid is mostly packaged in barrels, firefighters usually transport the foam liquid barrel to the top of the fire truck and pour it through the top opening of the foam liquid tank, or pump the fire extinguishing agent into the foam liquid tank through a liquid pump. The injected foam liquid hits the liquid surface at a certain speed, and a large amount of foam is generated under mechanical action. A large amount of air will be mixed into the pumping process of some liquid pumps, which accelerates the formation of foam, causing the foam tank to be filled with foam, and overflowing from the foam liquid tank as the liquid level rises, resulting in the foam liquid unable to fill the fire truck. About 10% to 25% of the space in the fire truck tank is filled with bubbles, and the fire truck cannot be filled, seriously affecting the transportation efficiency of the fire truck.

The connection between the upper tube and the lower tube effectively prevents the mixing of air during the injection process, which causes the foam fire extinguishing agent to foam. The trumpet-shaped lower tube expands the area of ​​the foam fire extinguishing agent tank opening of the fire truck, facilitating filling. In addition, the present application also realizes the filling of multiple barrels of foam fire extinguishing agent at the same time through the setting of the relay tank, providing a steady supply to the storage tank, thereby improving the filling speed of the fire truck. At the same time, since the pipeline is deep into the bottom of the relay tank, it can prevent the generated bubbles from being brought into the filling system. At the same time, through the optimized selection of the first booster pump, it can effectively avoid the stirring of the foam fire extinguishing agent and the introduction of gas during the filling process, causing a large amount of foam to be generated, thereby affecting the filling efficiency of the fire truck and improving the single filling volume of the fire truck. Storing foam fire extinguishing agents on shelves reduces the labor and management intensity during storage and outbound operations, allowing rescue manpower to be concentrated on firefighting and rescue operations. It also makes it easier to manage multiple foam fire extinguishing agents, reducing labor management costs. This utility model allows for the rapid replacement of different fire extinguishing agents, saving time and effort, and greatly improving replacement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Under normal circumstances, in order to fill the fire extinguishing agent into the fire truck in time when a fire occurs, a certain amount of foam fire extinguishing agent is pre-stored in the storage tank 205 and the relay tank 201. At this time, the foam fire extinguishing agent stored is mostly a foam fire extinguishing agent with a relatively wide fire extinguishing range.

At the same time, the drain switch at the bottom of the storage tank 205 in the common group is opened to discharge the common foam fire extinguishing agent in the storage tank 205 into the relay tank 201. The common foam fire extinguishing agent in the relay tank 201 is quickly drawn out through the refilling mechanism 400 and poured into the empty fire extinguishing agent barrel. After emptying, the specified foam fire extinguishing agent can be filled into the relay tank 201, thereby achieving rapid filling of the fire truck. Of course, if space is limited, it is also feasible to use only one relay tank 201, corresponding to one storage tank 205 and the first booster pump 203. In actual application, the number of relay tanks 201, storage tanks 205, and the first booster pump 203 can be set according to actual needs and is not specifically limited here.

[0034] The present invention focuses on protecting the structural design of the entire foam fire extinguishing agent warehouse and does not involve improvements to the program. At least one switch control cabinet electrically connected to each device is provided in the warehouse for manually controlling the start and shut down of each device. Of course, at least one PLC controller electrically connected to each device is also provided in the warehouse. The control program of the first photoelectric switch 306, the second photoelectric switch, the first booster pump 203, the electromagnet 303, the second booster pump 402, the travel switch and other devices by the PLC controller is easy to implement. Those skilled in the art can design a PLC control program using basic PLC knowledge after knowing the design requirements of the motion stroke.

[0035] The suction mechanism in this application is used to fill the fire truck with foam fire extinguishing agent, and the fire truck is weighed before and after filling. After calculation, the filling volume can reach about 95% of the rated load of the fire truck, which greatly improves the filling volume of a single fire truck. Taking a foam fire truck with a liquid load of 12 tons as an example, compared with the conventional filling method, the solution in this application is used for filling. A single fire truck can be loaded with 1.2-2.4 tons of foam fire extinguishing agent, which effectively improves the filling efficiency and rescue efficiency of the foam fire truck.
