Description

Technical Field

[0001] The present invention relates to the technical field related to fire safety, and in particular to an intelligent fire extinguishing system for an underground parking lot. Background Art

[0002] With the advancement of my country's urbanization process and the widespread application of new energy, fire accidents involving new energy vehicles in underground parking lots have increased year by year. At present, there is no automatic fire extinguishing system for new energy vehicles in underground parking lots. New energy vehicle fires have high temperatures, produce large amounts of toxic gases, and pose explosion risks. They are extremely dangerous and can easily cause huge economic losses and casualties.

[0003] There is an underground parking lot fire extinguishing system such as CN110755771B, which includes a smoke alarm, a monitor and a mobile track installed above the parking space, and a control system installed in the monitoring room. When smoke is detected, the moving head on the mobile track is moved close to the smoke detection position, so as to concentrate on extinguishing the fire at that position and reduce the losses caused by the fire; the alarm information can be sent to the control end in time so that the control end can carry out rescue in time.

[0004] However, the automatic water sprinklers installed in this type of underground parking lot mostly spray from top to bottom, and the ignition point of new energy vehicles is mostly located in the battery box of the vehicle chassis, which makes it impossible to spray the fire extinguishing agent directly to the ignition point, and the spray intensity of the water sprinkler is insufficient to achieve the purpose of controlling the fire and preventing the spread of the fire; the trigger signal of the automatic water sprinkler is temperature, and the hysteresis is obvious.

[0005] At the same time, there are many difficulties for the fire department to deal with fires in new energy vehicles. First, it takes a certain amount of time for the police to arrive at the scene, and there is an obvious lag, during which the fire can easily spread; second, the underground parking lot has limited height requirements, and fire trucks cannot directly enter the underground parking lot; third, firefighters are required to use fire hoses to spray close to the scene, and the thick smoke, high temperature and battery explosion risks pose a threat to the personal safety of firefighters.

[0006] In view of this, we conducted in-depth research on the above issues, which led to the present case. Summary of the invention

[0007] The purpose of the present invention is to address the problems of existing response measures, such as obvious lag, insufficient spray coverage, insufficient spray intensity, low degree of automation, easy spread of fire and loss of life and property, and propose an underground parking lot intelligent fire extinguishing system with automatic fire detection and alarm, precise and effective disposal, low application cost and easy maintenance.

After receiving the operation instruction and arriving at the target parking space, it measures the temperature of the vehicle. If the temperature of the vehicle in the parking space is normal, the temperature of the adjacent parking space is measured. When the detected temperature exceeds 100°C, the car moving robot sends a confirmation message to the car moving management platform, and the confirmation message includes parking space information, temperature data and time information, etc.

[0030] When the detected temperature exceeds 100°C, the vehicle moving robot automatically performs the vehicle moving operation and moves the target vehicle to the isolation disposal cabin.

[0031] Preferably, the vehicle moving robot is equipped with a water mist sprayer to reduce and prevent the external heat radiation of the vehicle on fire during the process of moving from the parking space to the isolation disposal cabin;

[0032] The car moving robot is coated with heat insulating material to prevent the car moving robot from losing its function in a high temperature environment;

[0033] The vehicle moving robot can be wheeled or tracked, and is made of high temperature resistant material to avoid loss of its movement function in high temperature environments.

[0040] The spray pipe and nozzle of the isolation disposal cabin are of water injection type, so as to carry out immersion disposal of the vehicle on fire.

[0041] The architecture of the intelligent fire extinguishing system for underground parking lots can be divided into the perception layer, platform management layer, network service layer, disposal layer and security application layer.

[0043] On the one hand, multiple fire detectors are used to obtain fire-related data indicators to increase the richness and timeliness of relevant data indicators. On the other hand, the equipment management platform is used in conjunction with the car-moving robot and the isolation disposal cabin for rapid temporary response processing, which improves the speed of fire perception and handling capabilities, and effectively avoids problems such as fire spread and loss of personnel and property caused by delayed processing;

[0044] At the same time, the car-moving robots and isolation disposal cabins set up in response to environmental conditions such as fires of new energy vehicles in underground parking lots are different from the automatic water sprinklers set up in conventional underground parking lots, which spray from top to bottom. They adopt spray-type isolation disposal combined with smoke extraction, effectively achieving the purpose of controlling fire, preventing the spread of fire and improving safety. Rapid early treatment effectively reduces the pressure on the fire department and reduces the threat to the personal safety of firefighters posed by thick smoke, high temperature and battery explosion risks.
