Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of foam tank installation structures, and in particular relates to a foam installation structure for a fire-fighting foam tank. Background Art
[0002] In firefighting work, foam fire extinguishing systems are widely used due to their high efficiency and environmental protection characteristics. Fire trucks are mobile carriers of foam fire extinguishing systems, and their foam tanks need to be filled with a large amount of foam liquid. However, the traditional foam filling method has many shortcomings, which seriously affects the efficiency and safety of firefighting work.
[0003] Traditional foam application methods typically require the coordinated efforts of multiple firefighters. First, heavy foam barrels must be carried from the ground to the top of the fire truck, a time-consuming and labor-intensive process that can easily lead to injury or damage to the barrels due to improper handling. Second, on top of the fire truck, firefighters must manually align the foam barrel's discharge port with the foam tank's fill port and gradually pour the foam. This process requires firefighters to remain vigilant to prevent the foam from splashing or the barrel from slipping, further increasing the complexity and risk of the operation. Working at height is inherently risky, especially when manually operating on top of a fire truck. Accidents can have devastating consequences. Furthermore, foam barrels can easily break or slip during handling and pouring due to improper handling, resulting in wasteful foam and potential damage to firefighters and the fire truck. Utility Model Content
[0004] The purpose of the utility model is to provide a foam adding structure for a fire-fighting foam tank, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A foam adding structure for a fire foam tank, comprising:
[0007] A hanging frame is provided inside the hanging frame with a placement frame movably installed through a bearing, a protection strip is fixedly installed on one side of the placement frame, two connecting strips are fixedly installed on one side of the protection strip, and a funnel is hinged between the two connecting strips.
[0008] Preferably, a liquid baffle is fixedly installed on one side of the top end of the funnel.
[0009] Preferably, a lower liquid port is fixedly installed at the bottom of the funnel.
[0010] Preferably, a protective chain is provided on one side of the placement rack.
[0011] Preferably, a hand-cranked reducer is fixedly mounted on one side of the exterior of the hanging frame, and the hand-cranked reducer is connected to the shaft of the placement frame in a transmission manner.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] (1) The utility model only needs to turn the hand wheel of the hand-cranked reducer to complete the pouring process of the foam liquid, which significantly improves the working efficiency. Compared with the traditional installation method, the structure of the present application can greatly reduce the installation time. The hoisting frame and the placement frame are made of high-strength materials and can withstand large weight and impact force. Secondly, the placement frame can be freely flipped through the bearing, and the flipping angle is controllable, thereby avoiding the safety hazards caused by shaking or sliding of the foam liquid barrel during the pouring process. In this process, firefighters do not need to perform tedious high-altitude operations and manual dumping operations, which greatly simplifies the operation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1:
[0020] See also Figure 1 - Figure 2 As shown, a foam adding structure for a fire foam tank includes:
[0021] A lifting frame 1 is provided with a placement frame 2 movably installed inside the lifting frame 1 through a bearing. A protection strip 3 is fixedly installed on one side of the placement frame 2. Two connecting strips 4 are fixedly installed on one side of the protection strip 3. A funnel 5 is hinged between the two connecting strips 4.
[0022] Specifically, a liquid baffle 6 is fixedly installed on one side of the top of the funnel 5, a lower liquid port 7 is fixedly installed on the bottom of the funnel 5, a protective chain 8 is provided on one side of the placement rack 2, and a hand-cranked reducer 9 is fixedly installed on one side of the outside of the lifting rack 1, and the hand-cranked reducer 9 is connected to the shaft transmission of the placement rack 2.
[0023] As can be seen from the above, the lifting frame 1 is used to connect the crane, the placement frame 2 is used to place the foam barrel, and the placement frame 2 drives the foam barrel to tilt, so as to realize the pouring of the liquid inside it. The funnel 5 can make the liquid poured from the foam barrel enter the foam tank of the fire truck more accurately. The hand-cranked reducer 9 is a worm gear reducer, model NRV080, which can drive the placement frame 2 to flip by turning the handwheel on one side.
[0024] During use, firefighters simply place the foam bucket on the mounting frame 2 and secure it, then use a crane to lift the entire hoisting frame 1 to the top of the fire truck. Next, firefighters turn the mounting frame 2 by turning the handwheel, causing the foam bucket to tilt toward the funnel 5, and the foam automatically flows into the foam tank under the action of gravity.
[0025] Example 2:
[0026] See also Figure 1 and Figure 3 As shown, the structure and operation of this embodiment are substantially the same as those of the first embodiment, except that the funnel 5 structure is removed, a connecting port is welded at the discharge port of the foam barrel, and a hose is sleeved on the outside of the connecting port. The foam liquid is directly poured into the foam tank through the connecting port and the hose, which greatly simplifies the installation process and reduces the operating steps. Since the transfer process of the funnel 5 is omitted, the flow of the foam liquid is smoother and the replenishment speed is faster, thereby improving the replenishment efficiency.
[0027] The specific operation is to first open the cover of the foam barrel discharge port with a wrench, then weld the connection port, and then put the hose on the outside of the connection port. Then the operation is consistent with the first embodiment, and the hose is placed inside the foam tank to pour.
[0028] This application can be applied to the daily supply of fire stations. In the daily work of fire stations, the maintenance and supply of fire trucks are key links to ensure emergency response capabilities. In particular, in the foam fire extinguishing system, the sufficiency of foam liquid is directly related to the fire truck's ability to effectively fight fires at the fire scene. In order to improve the combat readiness of fire trucks, the fire station decided to adopt the fire foam tank foam installation structure of this application to optimize the foam liquid supply process, improve the supply efficiency, and ensure that each fire truck can complete the foam liquid supply in the shortest time and be in the best combat readiness at any time. The specific implementation steps are as follows:
[0029] S1. First, the material manager of the fire station checks the foam liquid inventory to confirm the number of fire trucks that need to be supplied and the amount of foam liquid required for each truck. At the same time, the quality of the foam liquid is checked to ensure that the foam liquid used meets the standards.
[0030] S2: Based on the inspection results, the material manager takes out the corresponding number of foam barrels from the inventory and checks whether the barrels are intact and the discharge ports are unobstructed. Then, the foam barrels are transported to the fire truck parking area for reloading;
[0031] S3, the firefighter places the prepared foam liquid barrel steadily on the placement rack 2 and secures it firmly with the protective chain 8 to ensure that the foam liquid barrel does not shake or slip during the installation process, causing safety hazards;
[0032] S4, using the emergency fire truck crane equipment of the fire station, slowly lift the entire hoisting frame 1 to the top of the fire truck, close to the foam tank;
[0033] S5, use a hose to connect the funnel 5 on the placement rack 2 to the filling port of the fire truck foam tank, ensuring that the connection is tight and leak-free;
[0034] In step S6, the firefighter rotates the hand wheel to drive the hand-cranked reducer 9, causing the placement rack 2 to flip inside the hoisting rack 1. As the placement rack 2 flips, the foam liquid barrel gradually tilts toward the funnel 5. Under the action of gravity, the foam liquid flows from the discharge port into the funnel 5 and then into the foam tank through the hose.
[0035] S7. During the installation process, firefighters need to pay close attention to the flow of the foam liquid to ensure that the foam liquid can flow smoothly into the foam tank.
[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
