Description

Technical Field

[0001] This utility model belongs to the technical field of marine fire-fighting equipment, specifically relating to a marine equivalent fine water mist fire extinguishing device. Background Technology

[0002] With the rapid development of the global new energy vehicle industry, the number of ships used to transport these vehicles is increasing, making fire safety issues within the vehicle compartments particularly prominent. Components in new energy vehicles, such as lithium battery packs and high-voltage electronic control systems, are prone to fires in the event of collisions, short circuits, or thermal runaway. These fires are characterized by rapid fire spread, electrolyte leakage, release of toxic gases, and a high risk of reignition. The relatively enclosed space within the vehicle compartment, coupled with the complex three-dimensional structure created by densely parked vehicles, makes it difficult for traditional fire extinguishing devices to quickly and accurately control the fire. The following technical problems urgently need to be addressed:

[0003] Space limitations: The enclosed space inside the vehicle compartment and the dense parking of vehicles form a three-dimensional structure, making it difficult for traditional fixed fire extinguishing devices to cover complex fire source locations, resulting in fire extinguishing blind spots;

[0004] High environmental requirements for equipment: The high humidity of the ship environment makes the equipment susceptible to moisture. Traditional fire control boxes and other equipment are prone to failure due to moisture or high temperature, which leads to a decrease in system reliability. Utility Model Content

[0005] The purpose of this invention is to provide a marine equivalent fine water mist fire extinguishing device to solve the problems mentioned in the background art, such as the difficulty of fixed fire extinguishing devices in covering complex fire source locations and the easy failure of traditional fire control boxes and other equipment due to moisture or high temperature.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine equivalent fine water mist fire extinguishing device, comprising an installation box, a water pump, and a fire extinguishing system. The installation box contains a main control box and a pump control box, and a dehumidification box is installed on one outer wall of the installation box. A heat dissipation pipe is installed on the top of the installation box. The fire extinguishing system consists of two guide plates and multiple water outlet pipes, which are rotatably connected between the two guide plates. A water delivery pipe connected to one guide plate is installed at the water outlet end of the water pump. An infrared detector and an ultraviolet detector are installed at the bottom of the guide plate. Guide pipes and connecting columns are installed at both ends of the water outlet pipes, respectively. Multiple drive motors are installed on the surface of one of the guide plates.

[0007] In a further embodiment, the top of the dehumidifier box has a slot, and a moisture-absorbing plate is inserted into the slot. An air inlet groove is provided on one side of the outer wall of the dehumidifier box, and a dustproof net is installed in the air inlet groove.

[0008] In a further embodiment, an exhaust fan is installed on the lower half of the inner wall of the heat dissipation pipe, and an installation plate is installed inside the heat dissipation pipe. A cylinder is installed on the surface of the installation plate, and an exhaust sleeve that is movably connected to the heat dissipation pipe is installed on the driving end of the cylinder. Multiple heat dissipation holes are opened on the outer walls of the exhaust sleeve from top to bottom.

[0009] In a further embodiment, the two ends of the guide pipe are respectively connected to the guide plate and the outlet pipe, one end of the connecting column is fixedly connected to the outlet pipe, and the other end extends into the guide plate and is rotatably connected to the guide plate.

[0010] In a further embodiment, a driving bevel gear is fixed to the outer wall of the output shaft of the drive motor, and a driven bevel gear that meshes with the driving bevel gear is fixed to the outer wall of the connecting column.

[0011] In a further embodiment, the bottom of the water outlet pipe is provided with multiple mounting holes, and a fine water mist nozzle is installed in the mounting holes at the bottom of the water outlet pipe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] The shipboard equivalent fine water mist fire extinguishing device uses a dehumidification box that continuously absorbs moisture from the installation box through a detachable moisture-absorbing plate. Combined with the active exhaust design of the heat dissipation pipe, it keeps the installation box at a suitable humidity and temperature, ensuring stable operation of the main control box and pump control box, and significantly reducing the equipment failure rate.

[0014] The main control box, which is linked with infrared and ultraviolet detectors, can quickly identify the three-dimensional location of the fire source. The drive motor independently adjusts the angle of the water outlet pipe through the bevel gear set, realizing closed-loop control of "fire source positioning - direction adjustment - precise spraying", which greatly shortens the fire extinguishing response time.

[0015] The exhaust sleeve is moved by a cylinder, and the number of heat dissipation holes on the exhaust sleeve outside the heat dissipation pipe is adjusted. Thus, the heat dissipation rate in the installation box is automatically adjusted according to the ambient temperature to meet the needs of different environments. This marine equivalent fine water mist fire extinguishing device not only has good dehumidification and heat dissipation functions, but also can accurately extinguish fires at different fire locations, thus expanding its application range.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This utility model provides, for example Figure 1-6The illustrated marine equivalent fine water mist fire extinguishing device includes an installation box 1, a water pump 11, and a fire extinguishing system. The installation box 1 houses a main control box 2 and a pump control box 3. Both the main control box 2 and the pump control box 3 are existing technologies, and their structures will not be described in detail here. A channel for airflow is provided between the main control box 2 and the pump control box 3 to facilitate airflow. A dehumidification box 4 is installed on one outer wall of the installation box 1. A slot is provided on the top of the dehumidification box 4, and a moisture-absorbing plate 5 is inserted into the slot. An air inlet groove is provided on one outer wall of the dehumidification box 4, and a dustproof net is installed in the air inlet groove. Ventilation grooves are provided on the contact surfaces between the dehumidification box 4 and the installation box 1 to facilitate the entry of external air into the installation box 1 through the dehumidification box 4.

[0027] A heat dissipation pipe 6 is installed on the top of the mounting box 1. An exhaust fan 7 is bolted to the inner wall of the lower half of the heat dissipation pipe 6. The exhaust fan 7 has a speed adjustment function. A mounting plate 8 is bolted to the inside of the heat dissipation pipe 6. A cylinder 9 is bolted to the surface of the mounting plate 8. An exhaust sleeve 10, which is movably connected to the heat dissipation pipe 6, is installed at the drive end of the cylinder 9. Multiple heat dissipation holes are opened on the outer walls of the exhaust sleeve 10 from top to bottom. The dehumidification box 4 continuously absorbs moisture in the mounting box 1 through the detachable moisture-absorbing plate 5. Combined with the active exhaust design of the heat dissipation pipe 6, the mounting box 1 is kept at a suitable humidity and temperature, ensuring stable operation of the main control box 2 and the pump control box 3, and significantly reducing the equipment failure rate. At the same time, the cylinder 9 drives the exhaust sleeve 10 to move, adjusting the number of heat dissipation holes on the exhaust sleeve 10 outside the heat dissipation pipe 6, thereby automatically adjusting the heat dissipation speed in the mounting box 1 according to the ambient temperature to meet the usage requirements of different environments.

[0028] The fire extinguishing system consists of two baffles 13 and multiple outlet pipes 16. The multiple outlet pipes 16 are rotatably connected between the two baffles 13. The outlet end of the water pump 11 is equipped with a water supply pipe 12 that is connected to one of the baffles 13. The water pump 11 is placed in the fire water tank. An infrared detector 14 and an ultraviolet detector 15 are installed at the bottom of the baffles 13. The two ends of the outlet pipes 16 are respectively equipped with baffles 18 and connecting posts 21. The two ends of the baffles 18 are connected to the baffles 13 and the outlet pipes 16 respectively. One end of the connecting post 21 is fixedly connected to the outlet pipe 16, and the other end extends into the baffles 13 and is rotatably connected to the baffles 13. Sealing rings are installed at the contact points between the baffles 18 and the connecting post 21 and the baffles 13 to ensure the sealing of the baffles 13.

[0029] Multiple drive motors 19 are bolted to the surface of a guide plate 13. The number and position of the drive motors 19 correspond to the number and position of the water outlet pipes 16. A drive bevel gear 20 is fixed to the outer wall of the output shaft of the drive motor 19, and a driven bevel gear 22 that meshes with the drive bevel gear 20 is fixed to the outer wall of the connecting column 21. Multiple mounting holes are provided at the bottom of the water outlet pipe 16, and fine water mist nozzles 17 are installed in the mounting holes at the bottom of the water outlet pipe 16. The infrared detector 14 and the ultraviolet detector 15 are linked to the main control box 2, which can quickly identify the fire source. The drive motor 19 independently adjusts the angle of the water outlet pipe 16 through a bevel gear set to achieve precise fire extinguishing and significantly shorten the fire extinguishing response time. Through the atomization spray design of the fine water mist nozzle 17, the water flow per unit volume is formed into a fine water mist particle group. Its fire extinguishing efficiency is equivalent to the fire extinguishing coverage efficiency of a traditional water sprinkler system. The fine water mist works synergistically through surface cooling, suffocation, and radiant heat barrier mechanisms. Under the same fire source intensity, it uses less water than a traditional sprinkler system, but can achieve the same fire control and extinguishing effect, while significantly reducing water damage and system load.

[0032] Working principle:

[0033] The ship uses an equivalent fine water mist fire extinguishing device. When a fire occurs inside the cabin, the infrared detector 14 (detecting the heat radiation of the fire source) and the ultraviolet detector 15 (capturing the ultraviolet light of the flame) at the bottom of the deflector plate 13 are triggered synchronously and transmitted to the main control box 2 for data fusion. The coordinates of the fire source are calculated, and the main control box 2 sends a start command to the pump control box 3. The water pump 11 pressurizes the fire water and delivers it to the deflector plate 13 through the water pipe 12. At the same time, the main control box 2 sends an angle adjustment command to the drive motor 19 of the corresponding area according to the coordinates of the fire source. The active bevel gear 20 drives the driven bevel gear 22 to rotate, causing the connecting column 21 to drive the water outlet pipe 16 to turn towards the fire source. The pressurized water flow is divided into each water outlet pipe 16 through the deflector plate 13 and forms a mist jet through the fine water mist nozzle 17 to cover the surface of the fire source for fire extinguishing. After the fire is extinguished, the main control box 2 controls the water pump 11 to stop and the drive motor 19 to reset the water outlet pipe 16 to the initial position.
