Referring to fig. 1, the embodiment provides a fireproof method for a charging pile of an electric vehicle, and the fireproof method is applied to a charging pile for fireproof. This fill electric pile can be used for charging electric automobile, fills electric pile in addition and as one of the component parts of charging station, and its outward appearance and size can all set up according to actual need, as long as can satisfy the demand of charging of reality can. Wherein, should fill electric pile and include fire prevention base 1, shell 2, main part mechanism 3 that charges, thermal-insulated mechanism, conflagration early warning mechanism and heat dissipation mechanism.
The fire-protection base 1 is installed on the ground, and can be located above the ground, below the ground or flush with the ground. In the present embodiment, fire base 1 is a flame retardant base that can prevent burning by a fire. The shape and the size of the fireproof base 1 can be determined according to actual requirements, the existing base of the charging pile can be adopted, and a fireproof flame-retardant structure is arranged on the basis of the base to realize a fireproof function.
The shell 2 is arranged on the fireproof base 1 and is provided with a plurality of air holes or a plurality of air vents. The shell 2 can adopt the existing shell of the charging pile, and the surface of the shell can be coated with an anticorrosive material. The housing 2 may be dimensioned as desired and is typically made of a refractory material. In the present embodiment, the housing 2 is a rectangular or cylindrical housing, but of course, other shapes of housings may be used. In the present embodiment, both the inner and outer surfaces of the housing 2 are coated with a flame retardant layer, so that the housing 2 can prevent combustion, prevent further spread of fire, and better protect the structures in the housing 2.
The charging main mechanism 3 is located in the housing 2, fixed on the fireproof base 1, and used for charging the electric vehicle outside the housing 2. Charging main body mechanism 3 is the main part that fills electric pile promptly, and it can realize the function of charging to electric automobile. The charging main body mechanism 3 can charge the electric vehicle by a charger and is provided with a transformer and the like. The electric circuit of the charging main body mechanism 3 is easily burned under a high temperature condition caused by a fire, and thus, there is a possibility that a larger fire may be caused or the electric circuit or the electric vehicle may be affected, and therefore, it is necessary to protect it.
The heat insulation mechanism comprises a fireproof box 4, a roller shutter motor and a fireproof roller shutter 6, and also comprises a heat insulation soft layer 5 and a heat insulation plate 8. The flameproof box 4 is mounted in the case 2 and is located inside the top end of the case 2. The bottom end of the fire-proof box 4 is an open end and is arranged towards the fire-proof base 1. The roller shutter motor is installed in the fire-proof box 4 and is used to drive the movement of the fire-proof roller shutter 6. One end of the fire-proof rolling shutter 6 is installed in the fire-proof box 4, and the other end can be extended to be located between the housing 2 and the charging main body mechanism 3. The fire-proof shutter 6 is located in the fire-proof box 4 when retracted, so that the space between the housing 2 and the charging main body mechanism 3 is conducted.

The fire early warning mechanism comprises at least one temperature sensor and at least one flame detector, and the number of the temperature sensors is not directly related to that of the flame detectors. The temperature sensor is mounted on the housing 2 and is used to detect the real-time temperature of the housing 2. The temperature sensor can adopt DS18820 networking digital temperature sensing manufactured by DALLAS company in America, the DS18B820 can easily build a sensor network by utilizing the characteristic of a single bus and is connected with an I/O interface of a singlechip, and a plurality of DS18B20 can be connected to an address bus in parallel to realize communication with the singlechip. The flame detector is installed outside the housing 2 and serves to detect whether a fire is occurring outside the housing 2. The flame detector may employ an existing flame sensor for detecting flame information within its detection zone. The wireless type flame detector of the present embodiment is used for a fire detector responding to the light characteristics of a fire, that is, detecting the light intensity of flame combustion and the flicker frequency of the flame. The flame detector operates in a manner similar to a camera and detects the light characteristics of the flame within a sector in front of the mounting location. In this embodiment, the flame detector head employs a sensor that is capable of responding to the light information of the flame to collect corresponding light information, such as ultraviolet light, infrared light, and ultraviolet/infrared mixed light. When the flame detecting head is specifically installed, the flame detecting head can be fixed by adopting the existing installing mode of the detecting head, and even can be separated from the shell through a cable. When the detector is an ultraviolet detector, the detector can detect ultraviolet rays generated in flame combustion, namely the sensor is selected as an ultraviolet sensor, and the ultraviolet sensor can generate corresponding electric signals by detecting the ultraviolet rays. The sensor may employ a solid substance as a sensing element, such as silicon carbide or aluminum nitrate, or a gas filled tube, such as a geiger-m e el tube, as a sensing element. When the detector is an infrared detector, the detector can detect infrared rays generated in flame combustion, namely, the sensor is an infrared sensor which can generate corresponding electric signals by detecting the infrared rays. The infrared sensor can adopt an aluminum sulfide material as a sensitive element to detect infrared rays with the wavelength of 2.5-3mm, and also can adopt a lead selenide material or an aluminum tantalate material as a sensitive element to detect infrared rays with the wavelength of 4.4-4.6 mm. Of course, in practical applications, the selection of the sensor can be determined according to the light component in the flame generated by the combustion of the substance, that is, when the proportion of certain light is obviously larger than that of other light, the corresponding sensor can be selected as the detection element.
The heat dissipation mechanism includes a plurality of fans 7. A plurality of fans 7 are installed in the case 2 and serve to discharge air between the case 2 and the charging main body mechanism 3 through a plurality of ventilation holes or a plurality of ventilation windows. In other embodiments, the heat dissipation mechanism may include other structures, such as an air conditioner, as long as the charging body mechanism 3 can be cooled. Because the space and the cost of filling electric pile are limited, so just can realize the cooling through the effect of a plurality of fans 7 in this embodiment, be fit for in various regional environment.
Therefore, referring to fig. 2, the method for preventing fire of the charging pile of the electric vehicle in the embodiment includes the following steps.
And detecting whether a fire breaks out of the housing. In this embodiment, whether a fire occurs outside the casing is detected by the flame detector. In other embodiments, the presence or absence of a fire and the corresponding fire zone may be detected in other ways.
The real-time temperature of the housing is detected. In the present embodiment, the real-time temperature is detected by a temperature sensor.
When a fire disaster outside the housing 2 is detected, the shutter motor is driven to rotate to extend the fire shutter 6 to surround the charging main body mechanism 3. Further, when a fire is detected outside the housing 2, the charging of the electric vehicle by the charging main mechanism 3 is stopped. In addition, when a fire outside the housing 2 is detected, an image of the fire area may be photographed and the photographed image may be transmitted to a remote monitoring center. The remote monitoring center transmits the fire information to the client corresponding to the electric automobiles around the charging pile, and transmits the fire information to a fire-fighting emergency center. In some embodiments, when a fire is detected outside the housing 2, an alarm sound message is also sent, and the fire alarm message is transmitted to the remote monitoring center. The remote monitoring center transmits the fire information to the client corresponding to the electric automobiles around the charging pile, and transmits the fire information to the fire-fighting emergency center.
When detecting that no fire breaks out of the shell 2, the rolling shutter motor is driven to rotate so as to enable the fireproof rolling shutter 6 to contract, and whether the real-time temperature exceeds a preset temperature one is judged.
When the real-time temperature exceeds the first preset temperature, the fans 7 are driven to rotate until the real-time temperature is lower than the first preset temperature.
And when the real-time temperature is lower than the preset temperature, judging whether the real-time temperature is lower than a second preset temperature.
