Problems solved by technology

[0005] (1) The technical problem to be solved by the present invention is: the charging pile is an independent device; when charging, when there is a problem with the charging pile circuit, the circuit should be disconnected urgently, but the circuit can only cut off the power supply. If the circuit catches fire, the It is impossible to continue to protect the circuit, causing the circuit to expand and burn. In severe cases, the entire charging pile and charging equipment will be burned, and the safety performance is low.

Embodiment 2

[0047] The scheme in embodiment 1 is further introduced below in conjunction with specific working methods, see the following description for details:

[0048] Such as figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 15 As shown, as a preferred embodiment, the sealing mechanism 2 includes a slide rail 201, the slide rail 201 is fixedly connected to the side of the inner wall of the charging case 1 and located on both sides of the cooling hole 102, and the inner wall of the slide rail 201 is slidably connected to a sealing plate 202, the side of the sealing plate 202 is fixedly connected with a threaded sleeve 203, the inner thread surface of the threaded sleeve 203 is threaded with a threaded rod 204, the top of the threaded rod 204 is connected with a motor 205, and the motor 205 is fixedly connected with the inner side of the charging case 1 On the wall; during work, when the sensing control uni...

Embodiment 3

[0057] A method for emergency protection of a charging pile circuit, the method for protecting the circuit includes the following steps:

[0058] Step 1. Sensing circuit failure: When a combustion failure occurs in the circuit in the charging pile, the air switch 106 will trip immediately, and the sensing control unit 4 will sense the trip first, then immediately activate the sealing mechanism after receiving the smoke information, and send the fault information Send it to the personnel's mobile phone through the WIFI module;

[0059] Step 2. Sealing and fire extinguishing: the sealing mechanism 2 is activated to seal the cooling holes 102 to prevent the entry of oxygen. At the same time, the activation of the sealing mechanism 2 will trigger the fire extinguishing mechanism, which sprays the fire extinguishing agent into the charging case 1, so that the flame of the circuit is extinguished, and at the same time triggers the cooling mechanism 9 to cool the charging case 1, so ...

Abstract

The invention relates to an emergency protection circuit device and method for a charging pile based on the Internet of Things, belonging to the field of Internet of Things infrastructure. The emergency protection circuit device comprises a charging shell, wherein the front face of the charging shell is connected with a sealing door, the bottoms of the two sides of the charging shell are provided with heat dissipation holes, and the bottom of the inner wall of the charging shell is fixedly connected with an electric appliance mounting frame. According to the invention, a sensing control unit can control a sealing mechanism to seal heat dissipation holes under simultaneous sensing of tripping of an air switch and smoke, so air circulation in the charging shell is blocked, oxygen supply is blocked, and continuous expanded combustion of a circuit is blocked; when a fire disaster occurs, information is sent to a mobile phone end of a person through a WIFI module; and when the person approaches the charging pile in daily use, the Bluetooth module sends basic information to a mobile phone of the person, so interconnection between the charging pile and the mobile phone of the person is achieved through the operation, and the function of the Internet of Things is achieved.

Description

technical field [0001] The invention relates to an emergency protection circuit device and method for a charging pile based on the Internet of Things, belonging to the field of Internet of Things infrastructure. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. [0003] In the existing technology, the charging pile exists as an independent device. During normal use, personnel cannot know the operating parameters of the charging pile, or after encountering a charging pile accident, personnel cannot immediately know the status of the charging pile. specific situation. [0004] In addition, in the prior art, when there is a problem with the charging pile circuit during charging, t...
