For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The disclosed embodiments are intended to solve the problem that the existing charging carports have simple structures and do not have fire prevention and fire extinguishing functions. Because there are many sockets in the charging carport, many battery vehicles are charged in the charging carport. Once a certain position in the charging carport catches fire, the fire will easily spread, causing more battery vehicles in the charging carport to be burned, causing great losses to people. In view of this, the disclosed embodiments propose a new type of fireproof outdoor charging shed for electric vehicles. By setting a carport body with a C-shaped structure, when an electric vehicle is charged and catches fire, the carport body with its C-shaped structure guides harmful gases to flow along the C-shaped structure, and cooperates with the fire extinguishing device on the top to prevent smoke from escaping to the maximum extent. At the same time, through the data of the smoke alarm and the temperature sensor, the charging mechanism is powered off when an abnormality occurs, and then the fire is extinguished in the early stage of the electric vehicle fire, further solving the problem that the fire is easy to spread after the electric vehicle catches fire, causing more battery vehicles in the charging carport to be burned, causing great losses to people.

[0027] like Figures 1 to 5 As shown, a new type of fireproof outdoor charging shed for electric vehicles includes a fixed base 1, a shed body 2, a charging mechanism 3 and a fire extinguishing device 4. The fixed base 1 is fixed, and a shed body 2 is installed on one side of the fixed base 1. The shed body 2 is in a C-shaped structure. The charging mechanism 3 is installed in the shed body 2. The fire extinguishing device 4 is installed on the top of the shed body 2. The fire extinguishing device 4 is used to cooperate with the shed body 2 to complete the preliminary fire extinguishing work in the fire area to prevent the fire from spreading;

[0028] The carport body 2 with a C-shaped structure can provide good rain protection for electric vehicles in normal times. The existing electric carports use membrane structures or soft structures. When facing heavy rain, rainwater gathers on the top of the carport, causing the electric carport to deform or even be damaged, thereby affecting the use of the electric carport. The above-mentioned electric carport can allow rainwater to flow down along the carport body 2 with its C-shaped structure, thereby avoiding rainwater from gathering on the top of the carport and increasing the service life of the carport.

[0029] like Figure 2 It is shown that the carport body 2 is a double-layer structure, and the carport body 2 is arranged with transverse steel bars 5 at intervals, and the remaining positions are poured with cement; the carport body 2 is set as a double-layer structure for placing transverse steel bars 5 inside it, thereby increasing the hardness of the carport body 2 and avoiding deformation due to long-term use.

[0030] like Figure 5 As shown, the length of the fixed base 1 is greater than the projected length of the carport body 2. Setting the length of the fixed base 1 to be greater than the projected length of the carport body 2 is used to ensure the center of gravity of the carport body 2, thereby avoiding the carport body 2 from tipping over during use.

[0031] like Figure 1 As shown, a rectangular groove 11 is provided at the bottom of the fixed base 1. The rectangular groove 11 is provided at the bottom of the fixed base 1 to allow rainwater to flow from the rectangular groove 11 at the bottom of the fixed base 1 from a high-lying area to a low-lying area when it rains, thereby preventing accumulated water from soaking the fixed base 1 for a long time and causing corrosion thereof.

[0032] like Figure 1 As shown, a pad 12 is installed on one side of the fixed base 1. The pad 12 is used to assist the electric vehicle to enter the electric shed, and the pad 12 is an isosceles triangle. The fixed base 1 is in contact with the pad 12 for a section with a slope consistent with the inclination angle of the pad 12. The above arrangement can evenly disperse the pressure of the electric vehicle on the pad 12 on the slope of the fixed base 1.

[0033] like Figures 1 to 5 As shown, the fixed base 1 and the carport body 2 are integrally cast and formed, which can ensure the stability of the force of the electric carport and avoid damage to the electric carport due to long-term use.

[0034] like Figures 1 to 5 As shown, the fire extinguishing device 4 includes a smoke sensor 41, a temperature sensor 42, a water pipe 43 and a sprinkler head 44. The smoke sensor 41 and the temperature sensor 42 are both installed on the top of the carport body 2. The smoke sensor 41 and the temperature sensor 42 are used to detect the temperature in the carport body 2 in real time; the water pipe 43 is arranged close to the carport body 2, and one end of the water pipe 43 is fixedly connected to the fire hydrant; the water pipe 43 is used to transport water to the sprinkler head 44; the sprinkler head 44 is installed at one end of the water pipe 43, and the sprinkler head 44 is aimed at the charging mechanism 3. The sprinkler head 44 is used to fill water into the carport body 2 to achieve the fire extinguishing function;

[0035] During operation, when the smoke sensor 41 and the temperature sensor 42 detect data abnormalities at the same time, the control unit controls the fire pump to flush water into the water pipe 43, and the water is transported to the sprinkler head 44 through the water pipe 43. The sprinkler head 44 sprays water to extinguish the fire point of the carport body 2; since the carport body 2 is a C-shaped structure, after the carport body 2 catches fire, the toxic smoke will flow along the inner wall of the carport body 2 to the fire extinguishing device 4, so under the spray of the water flow of the fire extinguishing device 4, the smoke will encounter water and precipitate and fall to prevent the toxic smoke from flowing out.

[0036] like Figure 1 As shown, the angle between the sprinkler head 44 and the carport body 2 is 30°. Setting the angle between the sprinkler head 44 and the carport body 2 to 30° can make the water sprayed from the sprinkler head 44 flow better to the carport body 2, thereby improving the fire extinguishing efficiency.

[0037] The working principle of the utility model is that, by setting a carport body 2 with a C-shaped structure, when a fire occurs during charging of an electric vehicle, the carport body 2 with its C-shaped structure guides harmful gases to flow along the C-shaped structure, and cooperates with the fire extinguishing device 4 on the top to prevent the escape of thick smoke to the maximum extent; when the smoke sensor 41 and the temperature sensor 42 detect data abnormalities at the same time, the control unit controls the fire pump to flush water into the water pipe 43, and the water is transported to the sprinkler head 44 through the water pipe 43, and the sprinkler head 44 sprays water to extinguish the fire point of the carport body 2; since the carport body 2 is a C-shaped structure, the toxic smoke of the carport body 2 will flow along the inner wall of the carport body 2 to the fire extinguishing device 4 after the carport body 2 catches fire, so the smoke will be precipitated and fall when it meets water under the spraying of the water flow of the fire extinguishing device 4 to prevent the toxic smoke from flowing out.

[0038] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
