Description

Technical Field

[0001] The utility model relates to an automatic fire-fighting system for an electric vehicle shed. Background Art

[0002] With the continuous development of society, more and more high-rise buildings are springing up, and the storage of electric vehicles in cities has become a problem. More and more electric vehicles are spontaneously combusted when charging on floors. In order to prevent such incidents, it is necessary to build electric vehicle sheds to store electric vehicles to facilitate the charging and storage of electric vehicles. Electric vehicles still spontaneously combust during the charging process. In the prior art, due to the conditions in the electric vehicle shed, the fire-fighting facilities in the shed are only equipped with fire extinguishers, and the fire-fighting system on the floor has poor practicality for the shed. Once a fire occurs, it will ignite multiple bicycles, and the fire cannot be discovered in time after the fire, which will lead to increased losses. Due to limited fire-fighting measures and lack of fire-fighting systems, manual use of fire extinguishers to put out fires will face the risk of explosion, endangering the personal safety of residents.

[0003] The existing carport fire protection system uses a unified switch to control the sprinklers. When a fire occurs, all sprinklers will be activated at once. This has high requirements for water pressure and is prone to insufficient water pressure, resulting in poor fire extinguishing effect. In addition, water in areas where no fire occurs is wasted. Summary of the invention

[0004] In view of the above-mentioned deficiencies, the utility model provides an automatic fire-fighting system for an electric vehicle shed which can automatically monitor fires and extinguish fires.

[0005] In order to achieve the above purpose, the utility model adopts an automatic fire protection system for an electric vehicle carport, including a parking shed, a fire extinguishing unit, a monitoring unit, a computing platform, a control cabinet and a charging main circuit. The parking shed includes multiple fire partitions. The fire extinguishing unit includes a water pump, a solenoid valve, and a nozzle. Multiple nozzles are arranged in each fire partition. The solenoid valve is connected to the nozzle of each fire partition. The water pump outlet is connected to the solenoid valve. The water pump is connected to the water inlet pipe. The solenoid valve and the water pump are communicated with the control cabinet through the computing platform. The monitoring unit includes a flame detector and a camera. The flame detector monitors the entire parking shed. The camera is arranged in each fire partition to monitor the fire partition. The flame detector and the camera are both communicated with the control cabinet through the computing platform. The control cabinet is connected to the charging main circuit and controls the disconnection of the charging main circuit.

[0006] The above scheme is used to divide the parking shed into multiple fire compartments, and sprinklers are set according to the charging positions of the motors. Infrared and ultraviolet flame detectors are used to monitor the occurrence of fires, and the specific location of the fire is located through the image recognition algorithm of the camera. Local fire extinguishing is achieved by individually controlling the sprinklers in the fire compartments, ensuring the water pressure for fire extinguishing and saving water.

[0007] The utility model is further configured such that the size of the fire partition is divided according to the planning of the parking shed, and the number of sprinklers in each fire partition is proportional to the area of ​​the fire partition. The fire partition is divided as needed, and sprinklers are set according to the size of the fire partition, thereby improving applicability.

[0008] The utility model is further configured such that the sprinkler in each fire protection partition of the parking shed is connected to a solenoid valve.

[0009] The utility model is further configured that the fire extinguishing unit also includes an alarm device, the alarm device is electrically connected to the solenoid valve, the alarm device is communicatively connected to the computing platform, the alarm device is communicatively connected to the mobile phone APP and the fire monitoring, and relevant personnel can be notified in time.

[0010] The utility model is further configured to provide a current limiting protector in the control cabinet, the current limiting protector controls the disconnection of the charging main circuit, and the control cabinet supplies power to the water pump, the solenoid valve, the flame detector and the camera. The current limiting protector implements current limiting protection for the charging main circuit to prevent short circuit.

[0011] The utility model is further configured such that the flame detector is a red-ultraviolet composite flame detector, which has both infrared and ultraviolet detection functions and can detect flames in the first place, thereby achieving early detection and early disposal.

[0012] The utility model is further configured that the nozzle adopts a Laval nozzle, and the Laval nozzle can ensure the water pressure of the water outlet of the nozzle.

[0013] The utility model also adopts an automatic working method of an electric vehicle shed, comprising the following steps:

[0014] (1) The entire parking shed is monitored by flame detectors. When radiation that meets the characteristics of flames is detected, an alarm signal is sent out through the computing platform and control cabinet, and the main charging circuit is cut off;

[0015] (2) Monitor the fire zones in each fire zone through the cameras in the zone, identify the zone where the fire occurs, and upload the information to the control cabinet through the computing platform. The control cabinet sends a signal to start the water pump and the solenoid valve of the fire zone where the fire occurs;

[0016] (3) Based on the fire image captured by the camera in real time, the control cabinet uses the image recognition algorithm to select and activate the solenoid valve of the fire partition near the fire partition where the fire is located.

[0017] The beneficial effects of the utility model are that it adopts zoning protection, adopts multiple channels for water extraction, saves water, and ensures water pressure to prevent the flame from continuing to burn, thereby saving water and ensuring that the fire can be prevented from spreading; it adopts a variety of sensing technologies to conduct global monitoring of the charging area, and after a fire occurs, a variety of sensor signals are calculated to perform image confirmation of the fire location, scale and other information, and then the image algorithm of the control cabinet is used to determine the fire location and range, and the position and number of the nozzles to be started are selected by controlling the solenoid valve. The whole process is accurate, efficient, and energy-saving, ensuring the water pressure of the nozzles and ensuring the fire-fighting effect. BRIEF DESCRIPTION OF THE DRAWINGS
