Description

Technical Field

[0001] The utility model relates to a fire suppression device for an electric bicycle charging station. Background Art

[0002] At present, most communities and residences are equipped with electric bicycle charging stations for electric bicycles to charge. In the hot summer, electric bicycles may catch fire due to high temperature or cable aging during charging, which is likely to cause a fire. A fire suppression device is needed to carry out fire extinguishing work to minimize the property losses of vehicle owners as much as possible.

[0003] Existing fire suppression devices have single functions and poor fire extinguishing effects. They often cannot detect the occurrence of a fire in time, making it inconvenient to carry out fire extinguishing work in a timely manner. Most traditional fire suppression devices use simple automatic sprinklers or dry powder fire extinguishers. The sprinkler method can weaken the fire, but often cannot completely extinguish the fire. The dry powder fire extinguishing method has an unclear fire extinguishing effect and is likely to spread the fire to adjacent vehicles, both of which have certain limitations.

[0004] Therefore, it is necessary to provide a fire suppression device for an electric bicycle charging station to solve the above problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a fire suppression device for an electric bicycle charging station to solve the problems mentioned in the above background art.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A fire suppression device for an electric bicycle charging station includes a control box and an inhibitor tank. A PLC controller and an air compression pump are arranged inside the control box. A water-based foam fire extinguishing agent is stored in the inhibitor tank. Both ends of the air compression pump are respectively communicated with a feed pipe and a discharge pipe. The feed pipe is communicated with the inhibitor tank. One end of the discharge pipe penetrates through the control box and is connected with a conveying pipeline. A plurality of atomizing nozzles are equidistantly distributed at the bottom of the conveying pipeline. A flame detector is arranged at the bottom of the conveying pipeline. An audible and visual alarm is arranged on the top of the control box. The air compression pump, the flame detector and the audible and visual alarm are all electrically connected to the PLC controller.

[0008] Preferably, a plurality of flame detectors are provided. The plurality of flame detectors are equidistantly distributed at the bottom of the conveying pipeline, and two adjacent flame detectors are cross-designed.

[0009] Preferably, a box door is hinged to the front end of the control box, and an emergency stop button, an emergency start button, and a test button are arranged on the front end of the box door. The emergency stop button, the emergency start button, and the test button are all electrically connected to the PLC controller.

[0010] Preferably, an integrated touch screen is further arranged on the front end of the box door, and the output end of the integrated touch screen is electrically connected to the input end of the PLC controller.

[0011] Preferably, a water inlet pipeline is communicated with the rear end of the air compressor pump, and one end of the water inlet pipeline penetrates through the control box and is connected to the water supply pipeline of the external municipal administration.

[0012] Preferably, pulleys are arranged at the four end corners of the bottom of the control box.

[0013] The beneficial effects of the present utility model are as follows: The conveying pipeline is installed on the top inside the charging station shed. The flame detector is used to detect the existence of a fire source. When a fire source exists, through the flame detector, the PLC controller, and the sound and light alarm, an alarm can be issued to remind people to come quickly. Through the PLC controller, the air compressor pump, the inhibitor tank, the aqueous foam fire extinguishing agent, the discharge pipe, and the atomizing nozzle, the electric vehicles in the shed can be extinguished. Through the equidistant distribution of a plurality of atomizing nozzles, the fire extinguishing range can be expanded, facilitating the uniform extinguishing of the fire. The aqueous foam fire extinguishing agent (such as silica aerogel) has good heat insulation effect, and is safe, environmentally friendly, and pollution-free. After extinguishing the fire, it vaporizes without residue and can be used for extinguishing fires caused by thermal runaway of lithium batteries. After the fire extinguishing agent is released, the device can pump water through the air compressor pump to the water inlet pipeline to provide continuous and stable water supply guarantee for subsequent fire extinguishing work.
