Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle fire prevention control, and in particular to a fire monitoring and extinguishing system for a refueling truck. Background Art
[0002] With the rapid development of society and economy and the continuous improvement of people's living standards, people's demand for fuel for daily use, such as gasoline, diesel, and liquefied natural gas for daily use, has gradually increased. As a result, the number of refueling trucks and gas stations has also increased. Since fuel is a flammable and explosive fluid, the slightest carelessness can cause combustion and explosion accidents, resulting in casualties and property losses. This requires refueling trucks and gas stations to have very good fire and explosion prevention capabilities.
[0003] Most fuel trucks feature fire and explosion prevention systems, including static-dissipating grounding devices. Static-dissipating mopping tape and grounding wires are used to promptly dissipate static electricity generated during transportation and operation, preventing explosions caused by static discharge. Fire extinguishers and asbestos sprayers are also available to extinguish fires. However, these traditional methods cannot eliminate combustion and explosions caused by ignition sources such as open flames, lightning, and impacts. Furthermore, deploying fire extinguishers requires manual intervention, increasing risks to personnel and property.
[0004] Currently, there are no national standards for refueling vehicles. According to the standards, refueling vehicles only need to be equipped with two manual fire extinguishers to be allowed on the road. However, in actual operation, there is a high possibility of fires occurring in the engine compartment, the fuel inlet, or the refueling machine. If a fire occurs, it cannot be discovered immediately, and the best time to extinguish the fire is missed. Summary of the Invention
[0005] To this end, the present invention provides a fire monitoring and extinguishing system for a refueling truck to solve the problem that it is difficult to quickly detect and extinguish a fire in the existing refueling truck.
[0006] In order to achieve the above object, the present invention provides the following technical solutions:
[0007] The present invention discloses a fire monitoring and fire extinguishing system for a refueling truck. The system comprises: a fire extinguisher tank, a solenoid valve, a sprinkler pipe, an on-board computer, a fire monitoring sensor and a control panel. The fire extinguisher tank is installed in a reserved position on the vehicle body. The fire monitoring sensor is set at a position on the refueling truck body where fire is likely to occur. The fire detector is connected to the on-board computer. Sprinkler pipes are installed at the fire-prone position, and the sprinkler pipes are connected to the fire extinguisher tank. A solenoid valve is installed on each sprinkler pipe. The opening or closing of the solenoid valve is controlled by the on-board computer or the control panel to realize automatic spraying of the fire extinguishing agent.
[0008] Furthermore, the fire extinguisher tank is installed at the connection between the front of the vehicle and the body, and foam fire extinguishing agent is set in the fire extinguisher tank. The outlet of the fire extinguisher tank is connected to a mechanical valve and a solenoid valve. The mechanical valve is in a normally open state, and the solenoid valve is connected to the on-board computer.
[0009] Furthermore, the fire extinguisher tank is connected to a metal pipe through a fire-resistant hose, and the metal pipe is welded to the top, sides and bottom of the refueling truck. The metal pipe has multiple diversion ports, each of which is connected to a sprinkler pipe. A flat nozzle is installed on the sprinkler pipe, and foam fire extinguishing agent is sprayed to the fire occurrence point through the nozzle.
[0010] Furthermore, a solenoid valve is installed on the spray pipe, and the solenoid valve is connected to the on-board computer, and the opening or closing of the solenoid valve is controlled by the on-board computer.
[0011] Furthermore, the locations where the nozzle is installed include the tank top, both sides of the tank, the tank bottom, the engine compartment, the oil unloading port, and the refueling tank of the refueling truck.
[0012] Furthermore, the fire monitoring sensor includes: a temperature sensor, a smoke sensor, a light spot monitoring sensor and an image acquisition device. The temperature sensor collects the temperature of the location, the smoke sensor monitors the smoke concentration value in the environment, the light spot monitoring sensor monitors whether sparks appear, and the image acquisition device captures images of the installation locations of the temperature sensor, smoke sensor, and light spot monitoring sensor.
[0013] Furthermore, the temperature sensor, smoke sensor, light spot monitoring sensor and image acquisition device are all connected to the on-board computer. The on-board computer analyzes the collected data, compares it with the set threshold, and issues an alarm in time. The image acquisition device determines whether a fire has occurred based on the collected images and accurately locates the location of the fire.
[0014] Furthermore, the on-board computer is installed in the cab. The on-board computer analyzes and compares the data from the fire monitoring sensor, determines whether a fire has occurred, and gives corresponding alarm information. The solenoid valve on the sprinkler pipe can be manually controlled to open through the control panel. At the same time, the on-board computer can automatically control the solenoid valve on the sprinkler pipe corresponding to the alarm fire location to open and spray foam fire extinguishing agent.
[0015] Furthermore, the on-board computer sends the alarm information to the command center and the driver's mobile terminal through the mobile communication network, and the fire extinguishing system can be activated through remote control to open the solenoid valve on the corresponding position of the sprinkler pipe to extinguish the fire.
[0016] Furthermore, the vehicle body is equipped with a collision monitoring sensor and a rollover monitoring sensor to monitor whether the vehicle has a collision or rollover.
[0017] The present invention has the following advantages:
[0018] The present invention discloses a fire monitoring and extinguishing system for a refueling truck. The system monitors whether a fire occurs in the refueling truck through temperature sensors, smoke sensors, and light spot monitoring sensors. The on-board computer can, based on the specific location of the fire, open the solenoid valve of the sprinkler pipe near the fire site through manual control, system control, or remote control to spray fire extinguishing agent toward the fire site, thereby achieving accurate and rapid fire extinguishing and improving the safety of the refueling truck.

[0026] Example
[0027] This embodiment discloses a fire monitoring and extinguishing system for a refueling truck, comprising: a fire extinguisher tank 1, a solenoid valve 2, a sprinkler pipe, an onboard computer 3, a fire monitoring sensor 4, and a control panel. The fire extinguisher tank 1 is installed in a reserved position on the vehicle body, the fire monitoring sensor 4 is set at a location on the refueling truck body prone to fire, the fire detector is connected to the onboard computer 3, a sprinkler pipe is installed at the fire-prone location, and the sprinkler pipe is connected to the fire extinguisher tank 1. A solenoid valve 2 is installed on each sprinkler pipe, and the opening or closing of the solenoid valve 2 is controlled by the onboard computer 3 or the control panel to achieve automatic spraying of the fire extinguishing agent.
[0028] The fire extinguisher tank 1 is installed at the junction of the vehicle's front and body. It clips onto the vehicle's body, allowing for installation of tanks of varying sizes and weights. The tank 1 contains a foam fire extinguishing agent. The tank's outlet is connected to a mechanical valve 6 and a solenoid valve 2. Mechanical valve 6 is normally open, and solenoid valve 2 is connected to the vehicle's onboard computer 3. To replace the fire extinguisher tank 1, close mechanical valve 6 to facilitate replacement. Once the replacement is complete, open mechanical valve 6, ensuring it remains normally open. Simply controlling solenoid valve 2 allows the foam fire extinguishing agent to flow out.
[0029] The fire extinguisher tank 1 is connected to a metal pipe 5 via a fire-resistant hose. The pipe is welded to the top, sides, and bottom of the tanker truck. The pipe has multiple diversion ports, each connected to a sprinkler pipe. A flat nozzle 7 is installed on the sprinkler pipe, spraying foam fire extinguishing agent toward the fire site. The nozzle is also installed with a solenoid valve 2, which is connected to an onboard computer 3 and controlled by the onboard computer 3 to open or close it. Sprinklers 7 can be installed on the tank top, sides, bottom, engine compartment, unloading port, and refueling tank. Fire-prone areas can be monitored more closely and additional sprinkler pipes installed.
[0030] The fire monitoring sensor 4 includes a temperature sensor, a smoke sensor, a light spot monitoring sensor, and an image acquisition device. The temperature sensor collects the temperature of the location, the smoke sensor monitors the smoke concentration in the environment, and the light spot monitoring sensor detects the presence of sparks. The image acquisition device captures images of the locations where the temperature sensor, smoke sensor, and light spot monitoring sensor are installed. The temperature sensor, smoke sensor, light spot monitoring sensor, and image acquisition device are all connected to the onboard computer 3, which analyzes the collected data and compares it with set thresholds. If the collected data detects that the ambient temperature exceeds a set standard temperature, the smoke concentration exceeds a set standard concentration, or sparks are present, an alarm is issued. The image acquisition device determines whether a fire has occurred based on the captured images, accurately locates the fire, and prevents false fire alarms.
[0031] The onboard computer 3, installed in the cab, analyzes and compares data from the fire monitoring sensor 4 to determine if a fire has occurred and generates a corresponding alarm. The control panel allows manual control of the opening of the solenoid valve 2 on the sprinkler pipe. Once the solenoid valve 2 opens, foam fire extinguishing agent enters the sprinkler pipe through the metal pipe 5 and is sprayed from the nozzle 7 on the sprinkler pipe toward the fire. If the vehicle collides or rolls over, the collision monitoring sensor 8 and rollover monitoring sensor 9 installed on the vehicle body monitor the vehicle for an accident and transmit a signal back to the onboard computer 3. If an accident such as a collision or rollover occurs, the system directly activates the fire extinguishing circuit to prevent it. The onboard computer 3 automatically controls the opening of the solenoid valve 2 on the sprinkler pipe corresponding to the fire alarm location to spray the foam fire extinguishing agent.
[0032] The onboard computer 3 transmits alarm information to the command center and the driver's mobile device via the mobile communication network. Upon receiving the fire signal, the onboard computer 3 transmits it simultaneously to the command center and the user's mobile phone. If the system's judgment is incorrect and the cab is unoccupied, the remote command center or the driver can directly issue commands to the intelligent onboard computer 3 to activate or deactivate the fire extinguishing system. Remote control can activate the fire extinguishing system and open the solenoid valve 2 on the corresponding sprinkler pipe to extinguish the fire. These three methods enable fire monitoring of refueling trucks, enhancing safety.
[0033] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
