Description

Technical Field

[0001] The utility model belongs to the technical field of ship fire fighting, and in particular relates to an intelligent engine room fire extinguishing device. Background Art

[0002] A fire occurring on a ship during navigation may cause navigation interruption, affect route plans, and even endanger the operation of the entire shipping network. In addition, the internal space of a ship is relatively closed and dense. Once a fire occurs, it will spread rapidly, seriously affecting the safety of crew members and passengers. Among the existing ship fire-fighting methods, the jet-type fire-fighting method is used for point-to-point fire-fighting, which has low fire-fighting efficiency. For areas of the ship that are difficult for personnel to enter, the fire can only be extinguished on the periphery first, making it difficult to extinguish the fire of the ship's core equipment in a timely manner.

[0003] Patent application number CN205405180U describes an intelligent fire-fighting vehicle for shipbuilding and repair, comprising a main control unit, a vehicle drive module, a fire source detection module, a water spray fire extinguishing module, and a buzzer alarm module. The main control unit is connected to the vehicle drive module, the fire source detection module, the water spray fire extinguishing module, and the buzzer alarm module. The water spray fire extinguishing module of the aforementioned device has low fire extinguishing efficiency, primarily relying on an alarm to alert staff to extinguish the fire. This device also has very low fire extinguishing efficiency in areas that are difficult for personnel to access. Therefore, it is urgent for those skilled in the art to resolve the aforementioned technical issues. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide an intelligent cabin fire extinguishing device. The intelligent cabin fire extinguishing device senses the position of the fire extinguishing area through a sensor unit, and the main control unit controls the driving component to drive the device body to move to the fire area, and sprays atomized fire extinguishing liquid through the nozzle of the fire extinguishing component to achieve high-efficiency automatic fire extinguishing.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An intelligent cabin fire extinguishing device includes a fire extinguishing component, a drive component, a main control unit and a sensor unit. The drive component includes a drive motor, a drive wheel and a frame. The drive wheel and the drive motor are mounted on the frame. The fire extinguishing component is mounted on the frame. The fire extinguishing component includes a nozzle, a water storage tank and a pressure pump. The nozzle and the pressure pump are connected to the water storage tank. The sensor unit is mounted on the frame. The main control unit is connected to the sensor unit and the drive component.

[0007] Furthermore, it includes a temperature sensor, a pressure sensor and a photoelectric smoke detector, the temperature sensor and the photoelectric smoke detector are installed on the vehicle frame, and the pressure sensor is installed in the water storage tank.

[0008] Installed on the vehicle frame, it can monitor temperature changes in the surrounding environment in real time. Once abnormally high temperatures are detected, indicating a possible source of fire, the main control unit is immediately notified to take countermeasures, detect the fire source early, and improve fire prevention and initial firefighting effectiveness. Also mounted on the vehicle frame, it is used to detect smoke concentration in the air. In the early stages of a fire, smoke often appears before open flames. Photoelectric smoke detectors can very sensitively capture smoke, providing early warning and increasing the proactive nature of firefighting efforts. Installed inside the pressure pump, it monitors the pressure of firefighting water or fire extinguishing agents in real time. When the pressure falls below the preset value, indicating that the fire extinguishing medium may be insufficient, the main control unit receives a signal and prompts a request to replenish or adjust the firefighting strategy to ensure effective firefighting operations. It is also an important safety measure to prevent firefighting failure or equipment damage due to low pressure.

[0009] Furthermore, the main control unit includes a microprocessor module, a sensor interface, a control circuit and a communication module; the sensor interface is connected to the sensing unit, the microprocessor module analyzes and processes the data transmitted by the sensing unit, and the microprocessor module controls the displacement of the driving component to a designated area through the control circuit; the microprocessor module controls the pressure pump of the fire extinguishing component through the control circuit to provide different pressures to the water storage tank, thereby controlling the water discharge speed of the nozzle.

[0010] The sensor interface, control circuit, and communication module together form an intelligent core control system, enabling comprehensive management and control of the fire apparatus rack. The sensor interface connects to various sensors and can receive real-time data such as temperature, smoke concentration, and internal pressure of the pressure pump. The microprocessor module performs real-time analysis and processing on the received data, facilitating the rapid and accurate determination of the fire source location and fire status. The microprocessor module uses the control circuit to guide the drive components (such as the drive motor and drive wheels) to move precisely, enabling the fire apparatus rack to quickly and accurately reach the designated fire source area, improving firefighting efficiency and accuracy. The microprocessor module can adjust the operating parameters of the firefighting components through the control circuit according to the actual fire source. For example, it controls the pressure provided by the pressure pump to the water storage tank, thereby adjusting the water output and water discharge rate of the sprinkler. This not only saves firefighting resources but also ensures maximum firefighting effectiveness. The presence of the communication module allows the main control unit to exchange information with the outside world, facilitating remote monitoring and operation, further improving the automation and intelligence level of the fire apparatus rack, reducing manpower requirements, and also providing timely assistance in emergency situations.

[0011] Furthermore, the fire extinguishing assembly also includes a bracket, the water storage tank is fixed to the bracket through a clamp connection, the nozzle is connected to the water storage tank through a pipe, and the pipe connects the nozzle and the pressure pump.

[0012] The bracket provides a stable support base for the water storage tank and is firmly connected to the bracket through a clamp. Even in a complex and bumpy environment, it can ensure that the water storage tank will not be displaced or loosened due to vehicle movement or fire-fighting actions, thereby ensuring the stable operation of the fire-fighting system. The clamp connection method is easy to install and disassemble. When the water storage tank needs to be replaced or its interior needs to be cleaned or repaired, it can be quickly removed, which greatly simplifies the maintenance process and improves work efficiency. The nozzle is directly connected to the water storage tank through a pipe, and the pipe is connected to the pressure pump. This layout allows the water in the water storage tank to be smoothly and efficiently transported to the nozzle under the action of the pressure pump, so that the fire-fighting action can be quickly implemented. Due to the use of pipe connection instead of a rigid structure, the fire-fighting component can adjust the position and angle of the nozzle according to actual needs, so that the fire-fighting coverage area is wider and adaptable to a more diverse fire scene environment.

[0013] Furthermore, the bracket is mounted on the vehicle frame by bolts.

[0014] Bolted connection is a sturdy and durable mechanical connection method that can ensure a strong fixation between the bracket of the fire extinguishing component and the frame. Even in complex firefighting operation scenarios, it can withstand high-intensity impact and vibration to maintain the stability and safety of the fire extinguishing component. Bolted connection is easy to install and disassemble. If the fire extinguishing component needs to be maintained, upgraded or replaced, it can be easily done by unscrewing the bolts. No special tools or techniques are required, which greatly improves the convenience of equipment maintenance. By adjusting the degree of tightening of the bolts, the angle and height of the bracket can be fine-tuned according to actual needs, so that the fire extinguishing component can be more adaptable to different terrain conditions and fire scene requirements. The bolt installation method is widely used in the industry, and the parts are highly standardized, easy to purchase and replace, and reduce the subsequent maintenance costs.

[0015] Furthermore, a plurality of nozzles are arranged on the nozzle head, and the diameter of the nozzles is 1 mm.

[0016] Multiple small-diameter nozzles can disperse water flow or spray media so that it can cover a wider area when spraying, which is very beneficial for quickly suppressing the source of fire and improving fire extinguishing efficiency. Smaller diameter nozzles help to produce finer water mist or foam. This atomization effect can increase the surface area of contact between the fire extinguishing agent and the burning material, thereby accelerating the process of cooling and suffocating the flame and improving the fire extinguishing effect. Compared with a single large-diameter nozzle, multiple small-diameter nozzles can reduce the pressure loss when the fluid passes through the nozzle at the same total flow rate, which is beneficial to provide sufficient fire extinguishing agent delivery capacity under limited pump pressure conditions. Large-diameter nozzles may produce a large recoil force, while multiple small-diameter nozzles can disperse the recoil force, making the entire fire extinguishing system run more smoothly.

[0017] Furthermore, there are four drive motors in total, which are installed at the lower part of the frame. The drive motors are correspondingly connected to the drive wheels, and the main control unit is electrically connected to the drive motors.

[0018] Four drive motors control four drive wheels, enabling the fire apparatus rack to achieve omnidirectional movement, including forward, backward, lateral movement, and rotation. This is crucial for quickly approaching a fire source in complex and confined spaces. The independently controlled drive wheels enable the rack to instantly adjust to the actual situation, improving its ability to respond to unexpected situations, such as avoiding obstacles and adapting to uneven terrain. This greatly enhances its maneuverability and adaptability in fire environments. The electrical connection between the main control unit and the drive motors means that the speed and direction of each drive motor can be precisely controlled, enabling more accurate movement and posture adjustment. This is crucial for accurately locating the fire source and quickly implementing firefighting operations. The distributed and independent drive of the four drive wheels reduces the risk of failure due to single points of failure, increases the stability and reliability of the entire fire apparatus rack, and ensures its continued effectiveness in emergency rescue situations. The four drive motors work together to provide powerful driving force and load capacity, ensuring that the rack maintains good mobility and firefighting efficiency even when carrying heavy loads (such as a fully loaded water tank).

[0019] The utility model has the following beneficial effects:

[0020] The utility model uses the temperature sensor and the photoelectric smoke detector in the sensing unit to cooperate with each other to detect whether a fire occurs in an area within the ship. When a fire is determined to have occurred, the main control unit controls the device to move to the fire area and controls the pressure pump through the data of the pressure sensor to make the fire extinguishing liquid in the water storage tank spray out from the nozzle to extinguish the fire point. The device can automatically go to the fire area to automatically extinguish the fire and adjust the water flow rate of the nozzle, with high fire extinguishing efficiency. It is safer and more convenient than manual fire extinguishing.

[0021] The nozzle in the fire extinguishing assembly is provided with multiple water spray holes, and the diameter of the water spray holes is very small. The fire extinguishing liquid sprayed out is in the form of mist, which can cover a wider area when spraying. This is conducive to quickly suppressing the fire source and improving the fire extinguishing efficiency.

[0022] The driving wheels of the device are connected to different driving motors respectively, and the rotation speed of each driving wheel can be flexibly controlled to achieve the turning problem of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

The drive motor 32 is electrically connected to the main control unit 4. A fire extinguishing assembly 2 is installed on the top of the frame 1 and is connected and fixed to the top of the frame 1 through a bracket 24. The water storage tank 22 is fixed to the bracket 24 through two clamps 26. A pressure pump 23 is provided at the head end of the water storage tank 22, and the pressure pump 23 is connected to a pipe 25. A clamp 26 is installed at the end of the pipe 25.

[0032] In one embodiment, the entire device is sprayed with flame-retardant paint, and the connecting wires between the drive motor 32 and the main control unit 4 are wrapped with flame-retardant material. The main control unit 4 is also placed in a silicone insulation box to ensure that the high temperature in the fire area will not affect the operation of the device;

[0033] In actual use, the device can be used for patrol and remote control. The device is placed in the core area of the ship and patrols according to the preset route. When the temperature sensor and the photoelectric smoke detector detect heat and smoke, the main control unit 4 controls the drive component 3 to control the vehicle to move to the fire area. The main control unit 4 controls the pressure pump 23 through the control circuit to pump the fire extinguishing liquid in the water storage tank 22 through the pipe 25 and the nozzle 26 to extinguish the fire point, thereby eliminating possible fires.

[0035] Reference Figure 5 It can be seen that a plurality of water spray holes 211 are provided on the nozzle 21, and the nozzle 21 is funnel-shaped as a whole.

[0036] In one embodiment, the diameter of the water spray hole 211 of the nozzle 21 is 1 mm, which can make the fire extinguishing liquid in the water storage tank 22 be sprayed out in the form of mist. The smaller diameter nozzle helps to produce finer water mist or foam. This atomization effect can increase the surface area of contact between the fire extinguishing agent and the burning material, thereby accelerating the process of cooling and suffocating the flame and improving the fire extinguishing effect. A larger-diameter water spray hole is also provided in the center of the nozzle 21. The staff can remotely control the water spray hole in the center of the nozzle 21 to aim at the fire point, thereby achieving point-to-point fire extinguishing.
