Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a modular cooling device applied to a dump-type fire truck. Background Art

[0002] With the continuous promotion of new energy vehicles, new energy vehicles have long been integrated into our lives. However, new energy vehicles are mainly powered by batteries. The batteries have relatively high internal energy. Once the battery pack is damaged to a certain extent and a fire occurs, it often shows a rapid development trend. Moreover, the discharge of the battery pack is a chemical reaction. Once the battery pack is damaged, the internal environment of the battery is destroyed, which intensifies the chemical reaction and makes it easy to cause dangerous situations such as explosions. The chemical composition inside the battery is diverse. Even if it is isolated from the air, it will release a lot of heat, harmful gases and produce toxic waste residues after the explosion, which not only increases the difficulty of fire handling, but also pollutes the environment.

[0003] To this end, we propose a modular cooling device that can be applied to dump fire trucks, has good maneuverability, and is easy to operate. Utility Model Content

[0004] The purpose of the utility model is to provide a modular cooling device applied to a dump fire truck, so as to solve the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A modular cooling device for a dump fire truck comprises a container body and a pedal bridge. The container body is provided with a water injection unit, a spraying system, a traction device and a liquid level temperature sensing mechanism.

[0007] Furthermore, the water injection unit is installed on the front box plate at the front end of the container body; specifically, there are two groups of water injection units, and the two groups of water injection units are symmetrically arranged on the front box plate with the central axis of the front box plate as the symmetry axis, and each group of water injection units is composed of a number of water injection pipe joints, and each water injection pipe joint is connected to the interior of the container body.

[0008] Furthermore, the sprinkler system is installed on the top of the inner side of the container body, wherein the design of the sprinkler system is mainly to suppress the smoke generated during the combustion process of the car, and at the same time cooperate with the water injection unit to play an auxiliary fire extinguishing and cooling role. Specifically, the sprinkler system includes two water distribution pipes installed on both sides of the top of the container body, and a number of branch pipes are installed on the two water distribution pipes, and a number of nozzles are installed at the bottom of each branch pipe facing the bottom of the container body. At the same time, the front ends of the two water distribution pipes are installed with sprinkler pipe joints, and the two sprinkler pipe joints are fixedly installed on both sides of the front box plate of the container body.

[0009] Furthermore, the traction device is located inside the container body and is installed on the front box plate at the front end of the container body. The main function of the traction device is to use the vehicle's towing hook to tow the vehicle into the container body, so as to isolate the accident vehicle from the outside world and provide sufficient safety protection for subsequent vehicle fire-fighting operations. At the same time, it can also prevent harmful and toxic substances produced by vehicle combustion from continuing to spread into the air and pollute the environment. In order to achieve the traction transfer of the vehicle, the traction device is composed of a winch, a steel wire traction cable and a steel cable guide, wherein the winch is installed on the front box plate near the top of the container body through a bracket, and one end of the steel wire traction cable is wound on the winding drum, and the other end of the steel wire traction cable is installed with a traction hook after passing through the steel cable guide.

[0010] Furthermore, the winch adopts a double-drum electric winch or an electric reel. When the winch adopts an electric reel, two electric reels should be installed. A shield is installed on the front side of the bracket. The design of the shield can, on the one hand, prevent the vehicle flame from directly contacting the motor before it is completely extinguished, causing damage to the winch, and on the other hand, prevent the sprinkler system from spraying water directly onto the motor when working.

[0011] Furthermore, the liquid level and temperature sensing mechanism is installed on the front box plate at the front end of the container body. The design of the liquid level and temperature sensing mechanism is mainly to facilitate fire rescue personnel to always pay attention to the water injection depth and temperature in the container body.

[0013] Furthermore, movable wheels are installed at the bottom of both ends of the container body, the door at the rear end of the container body is a double-opening door, and the edge of the door is provided with a high-temperature resistant and fire-proof sealing strip. The entire container body is welded with steel plates, and the container body wall adopts a double-layer design, and the inside of the wall is filled with heat-insulating filler.

[0014] Furthermore, in order to facilitate the rapid water injection operation into the container body, an overflow hole is opened at the top of the container body or on the side near the top of the container body, and a one-way vent valve is installed in the overflow hole to only allow the air flow inside the container body to be discharged outward.

[0015] Furthermore, baffles are installed on both sides of the interior of the container body. The baffles are mainly set to prevent the vehicle from swinging left and right, and to limit the vehicle to the left and right. A tire stopper and two drainage pipes are installed at the bottom of the container body near the front end. Valves are installed on the drainage pipe, sprinkler pipe joint and water injection pipe joint. The design of the drainage pipe is mainly to open the valve on the drainage pipe after the new energy vehicle fire is completely extinguished, and discharge the waste water used for fire extinguishing inside the container body into a designated location or designated container for treatment to avoid polluting the environment. The sprinkler pipe joint and the water injection pipe joint both use DN80 interfaces to adapt to the docking of fire truck hoses.

[0016] Furthermore, in order to more conveniently tow the vehicle into the container body, the pedal bridge is overlapped at the bottom of the rear end of the container body according to the wheel spacing on both sides of the accident vehicle after the rear door of the container body is opened.

[0017] Beneficial effects:

[0018] The utility model takes a container body as the main body, and installs a hanging ring that cooperates with the loading and unloading arm of a dump fire truck on the front box plate of the container body, and installs moving wheels and a positioning box beam on the bottom of the container body, so that the modular cooling device can achieve high maneuverability with the help of a dump fire truck. Moreover, when in use, the entire cooling device can be used to tow a new energy vehicle that has caught fire into the interior of the container body through a winch in combination with a steel wire traction cable and a pedal bridge for sealing and isolation. At the same time, with the help of a spray system and a water injection unit provided on the cooling device, the cooling device can cooperate with a fire sprinkler truck to achieve water injection and fire extinguishing. At the same time, with the help of the spray system, harmful gases such as smoke and dust generated during the combustion of the vehicle can be effectively reduced. During the fire extinguishing process, the burning vehicle is completely isolated from the outside world, and combined with water injection and spraying measures, the fire extinguishing speed of the new energy vehicle can be effectively improved, while having a good protective effect on firefighters, surrounding people, buildings and the environment.
