Description

Technical Field

[0001] The utility model relates to the technical field of intelligent early warning and automatic fire extinguishing, in particular to a fire early warning and automatic fire extinguishing system for an electric vehicle charging shed. Background Art

[0002] As a means of transportation, electric bicycles are now widely used and adopted by the public due to their remarkable convenience. At the same time, charging sheds, supporting facilities that provide charging services for electric bicycles, are also increasing in communities and public places. However, due to the special properties of the batteries that power electric bicycles, they are prone to spontaneous combustion during frequent charging. Furthermore, most charging sheds are located in open environments, exposed to the elements for long periods of time, and the charging circuits are prone to aging, further increasing the potential for fire accidents.

[0003] E-bikes are often parked at high density in charging sheds. If a fire breaks out on one of these e-bikes, if it's not detected and dealt with promptly, it could easily trigger a chain reaction, rapidly igniting surrounding vehicles and potentially leading to a major fire. This would not only cause significant economic losses but also pose a serious threat to the lives of community residents.

[0004] Although fire-fighting equipment is currently installed around charging sheds, it usually requires manual operation. Since most charging sheds are unmanned, fires are often difficult to detect and deal with in a timely manner, which can easily lead to the rapid spread of fire and cause immeasurable serious consequences.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a fire warning and automatic fire extinguishing system for electric vehicle charging sheds. Utility Model Content

DETAILED DESCRIPTION

In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution for the fire warning and automatic fire extinguishing system of the electric vehicle charging shed: it includes a charging shed crossbeam 17, a support rod 18 is installed on the charging shed crossbeam 17, and a fixing plate 19 is provided on the top of the crossbeam, a hook 20 is installed on the crossbeam, and an early warning fire extinguishing component is provided under the charging shed crossbeam 17. The early warning fire extinguishing component includes a medicine cabinet 1, a water-based medicine bottle valve body and a start solenoid valve are provided inside the medicine cabinet 1, and a controller 2 is provided on the adjacent side of the medicine cabinet 1. The controller 2 has remote feedback alarm and remote control functions. The controller 2 is connected to the regional box 4, which is provided with an input module, an output module, and a conversion interface. The regional box 4 is connected to the sound and light alarm 3. The medicine cabinet 1 is connected to the medicine main pipe 5, and the end of the medicine main pipe 5 is connected to the injection main pipe 10. The injection main pipe 10 is installed on the charging shed beam 17, and a number of nozzles 11 are installed on the injection main pipe 10. The bottom of the charging shed beam 17 is provided with a temperature detector 8, a smoke detector 9, a cable-type heat detector 12, and a flame detector 6;

[0025] The controller 2 is connected to a signal feedback main line 16, the signal feedback main line 16 is connected to the flame detector 6 through a flame detector signal feedback harness 13, the signal feedback main line 16 is connected to the temperature detector 8 through a temperature detector signal feedback harness 14, and the signal feedback main line 16 is connected to the smoke detector 9 through a smoke detector signal feedback harness 15. A fixed bracket 7 is provided on the charging shed beam 17, and the temperature detector 8, flame detector 6 and smoke detector 9 are connected to the fixed bracket 7.

[0026] The working principle of this utility model:

[0027] First, after the system is activated, various detectors (including temperature detectors 8, smoke detectors 9, cable-type heat detectors 12, and flame detectors 6) are immediately put into operation. They are distributed in key areas of the charging shed. These detectors are highly sensitive and reliable, and can capture abnormal signals in the early stages of a fire, such as abnormal temperature increases, smoke formation, or the emergence of flames.

[0028] Once a detector detects a fire signal, it immediately transmits this emergency information to the signal feedback main line 16 via the corresponding signal feedback harness (flame detector signal feedback harness 13, temperature detector signal feedback harness 14, and smoke detector signal feedback harness 15). The signal feedback main line ensures that fire information reaches controller 2 as quickly as possible. The controller is responsible for receiving, processing, and responding to these fire signals.

[0029] Upon receiving a fire signal, controller 2 immediately analyzes and determines the authenticity and severity of the fire. Once the fire is confirmed and the fire extinguishing mechanism needs to be activated, controller 2 quickly issues a command to the reagent cabinet 1, activating the valve body of the water-based reagent bottle and the solenoid valve. This allows the reagent main to immediately begin delivering fire extinguishing agent to the injection main 10. Simultaneously, controller 2 activates the audible and visual alarm 3, emitting a strong audible and visual signal to alert personnel on site to the fire and urge them to evacuate as quickly as possible.

[0030] Fire extinguishing agent is evenly delivered via a spray main 10 to nozzles 11 installed at various locations. These nozzles 11 ensure that the agent is sprayed to the fire source with optimal coverage and intensity. Water-based agents, with their rapid, effective, and pollution-free extinguishing properties, quickly control the spread of fire and protect the charging shed and surrounding facilities.

[0031] In addition to automatic fire extinguishing, the system also features remote feedback alarms and remote start / stop control. This remote control system allows managers to monitor the fire situation in the charging shed in real time and remotely activate and deactivate the fire extinguishing system when necessary. This feature not only improves the efficiency and flexibility of fire response but also significantly reduces the risk of personnel entering a fire scene.

[0032] Furthermore, the input and output modules, conversion interfaces, and other components within Area Box 4 further enhance the system's compatibility and scalability. These components enable seamless integration with other security devices or management systems, enabling fire information sharing and coordinated control. This high level of integration and scalability provides strong support for building a more intelligent and comprehensive security protection system.

[0033] The electric vehicle charging shed fire warning and automatic fire extinguishing system provides a comprehensive and reliable solution for the safety protection of electric vehicle charging sheds with its advantages such as accurate fire warning, rapid fire extinguishing response, convenient remote control, and strong system compatibility.
