Description
Technical Field
The invention relates to the field of charging gun cables, in particular to a device for preventing liquid from overflowing from a liquid cooling cable of a charging gun.
Background
With the popularization of new energy automobiles, the configuration related to the new energy automobiles also needs to be improved, such as charging piles. The existing charging pile is connected with a charging gun through a cable, and the cable cannot reach and generate heat in the charging process, so that the service life of the cable is prolonged, and the charging efficiency is reduced; however, how to solve the potential safety hazard work of leaking of the liquid in the rifle line that charges becomes a difficult problem, the liquid in the rifle line that charges appears the potential safety hazard that liquid leaks and can cause at will when the during operation.
Disclosure of Invention
The invention aims to provide a device for preventing liquid from overflowing from a liquid cooling cable of a charging gun, which is installed in the liquid cooling cable and used for detecting whether the liquid leaks or not.
In order to achieve the purpose, the invention adopts the following technical scheme:
a device for preventing liquid of a liquid cooling cable of a charging gun from overflowing is characterized in that a liquid cooling layer is arranged between a shielding layer and a wire core layer of the liquid cooling cable, and at least 1 sensor for detecting whether the liquid overflows or not is arranged in the liquid cooling layer; the outside of sensor is provided with the waterproof layer, and series connection between a plurality of sensors.
Furthermore, a plurality of supporting pieces are arranged in the liquid cooling layer, and the sensor is attached to the supporting pieces.
Further, the sensor may employ a pressure sensor, or a liquid flow rate sensor.
Further, the sensor is connected with a monitoring device in the charging pile, and data collected by the sensor can be displayed through a display screen of the monitoring device.
Further, the monitoring device is connected with an alarm device.
According to the invention, the sensor with the waterproof layer is arranged on the liquid cooling layer, and the pressure, the pressure or the flow velocity of the liquid cooling layer is detected by the sensor to detect whether the liquid cooling layer leaks, so that the liquid cooling device is simple in structure, easy to realize and convenient to popularize.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention.
FIG. 2 is a schematic diagram of the electrical relationship of the present invention.
The labels in the figure are: 10. a core layer; 20. a shielding layer; 30. a liquid cooling layer; 31. a support member; 40. a sensor.
Detailed Description
As shown in fig. 1, the device for preventing liquid from overflowing from a liquid cooling cable of a charging gun provided by this embodiment, a liquid cooling layer 30 is disposed between a shielding layer 20 and a wire core layer 10 of the liquid cooling cable, the liquid cooling layer 30 is filled with cooling liquid, when the cable is processed, a plurality of supporting members 31 shaped like Chinese character 'gong' are processed on the outer surface of the wire core layer 10, then the shielding layer 20 is processed on the supporting members 31, and finally the cooling liquid is filled.
In this embodiment, at least 1 sensor 40 for detecting whether liquid overflows and leaks is arranged in the liquid cooling layer 30, a waterproof layer is arranged outside the sensor 40, the number of the sensors 40 is specifically determined according to the length and the wire diameter of the liquid cooling cable, the longer the cable is, the more the number of the sensors 40 is, the sensor 40 is arranged on the support 31 of the liquid cooling layer 30, the plurality of sensors 40 are connected with the same transmission line, so as to transmit the data collected by the sensors 40 to the monitoring device connected with the same, as shown in fig. 2, the monitoring device is a monitoring device which is arranged on the charging pile and is used for monitoring other information, the monitoring device is also connected with an alarm device, the alarm device can be provided with different alarm devices according to the position of the charging pile, if the charging pile is positioned in a place which is supervised by people such as a gas station, a sound alarm can be adopted, and if the charging pile is not supervised, such as a home underground parking garage, an alarm that sends information to a contact, etc., may be employed.
The sensors 40 can adopt pressure sensors, pressure sensors or liquid flow rate sensors, when leakage occurs, data collected by the sensors 40 can change, leakage-proof monitoring is achieved by using the characteristic, position information of the sensors 40 can be stored in the sensors 40, the collected data can be sent together, and leakage positions can be conveniently searched.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be covered within the scope of the present invention.
