Description
Technical Field
The invention belongs to the field of testing of new energy automobile fireproof materials, and particularly relates to a method and a device for testing a fireproof coating material on the surface of a new energy automobile power battery box body.
Background
Nowadays, the environment and energy have a very close relationship, wherein, as the national economic level of China is continuously improved, the living level of China is also improved. For the vehicle as a walking tool, the number of automobiles in China is increased by several times every year, and the exhaust emission of the traditional automobile aggravates the greenhouse effect and has the characteristics of high noise and serious air pollution, such as the emission of compounds such as carbon monoxide, carbon dioxide, sulfur oxides and the like into the air. These exhaust gases have a very adverse effect on the environment. In order to solve the environmental problem, China begins to vigorously develop new energy automobiles, such as electric automobiles which are produced by people at present. The electric automobile uses electric energy in the driving process, and no tail gas is discharged, so that energy is saved and the environment is protected. The safety of the power battery, which is a key component in the electric vehicle, is a key research content in the field.
At present, the research and development and production of new energy automobiles in China are in a preliminary stage, the safety of the new energy automobiles cannot be guaranteed powerfully, and when the electric automobiles collide or collide, batteries can be damaged by large impact force, extrusion puncture and the like, so that under extreme pressure, once battery shells are damaged and contacted with air, the batteries are extremely high in possibility of severe oxidation and even explosion. Second, when the vehicle is exposed to a heavy rain or other water-related conditions, the wiring between the batteries or the motor control system may be short-circuited due to water or vapor erosion, resulting in leakage of electricity, and once short-circuited, the temperature of the batteries rapidly rises, which may cause explosion or combustion. Therefore, how to slow down the speed of heat transfer to the outside of the battery pack when the lithium ion battery is burnt and how to slow down the speed of heat transfer to the inside of the battery pack when a fire breaks out of the battery pack on the contrary provide enough coping and processing time for personnel in the vehicle, thereby ensuring the safety of the personnel in the vehicle is very important.
At present, no effective and scientific test method and device exist for the fireproof material. Therefore, the method and the device for testing the fireproof material can effectively test the performance and the safety of the fireproof material on the surface of the box body of the new energy automobile when the battery pack in the new energy automobile is burnt. And the influence of adverse factors such as temperature and pressure when the battery in the automobile is damaged is highly reduced, so that the fireproof material on the surface of the power battery box body of the new energy automobile is fully tested.
Disclosure of Invention
The invention aims to design a method and a device for testing a new energy automobile fireproof material, and solve the problems explained in the background. The testing device mainly uses two robots to link, a special fireproof material (the material can be a fireproof coating of a metal plate, fireproof fiber, fireproof glass and the like) is fixed on a clamp, and the clamp can be controlled to move, so that the fireproof material moves. Meanwhile, the robot can realize independent movement of the fire spraying device and the pressure applying device, the robot demonstrator is used for respectively controlling the movement tracks of the fire-proof material, the fire spraying device and the pressure applying device, so that the method for testing the fire-proof material in different degrees under various conditions can be realized, and the testing time can reach 1-5 hours, so that the method and the device can fully test the performance of the fire-proof material.
The invention is realized by the following technical scheme:
the method and the device for testing the fireproof coating fully control the movement track of the flaming device, the movement track of the fireproof material and the movement track of the pressing device. The fire-proof material is heated by fully controlling the flame temperature, the temperature of the outer surface of the fire-proof material is fully collected in real time, the pressure applying device is fully utilized, high-pressure gas impact is applied to the fire-proof material, and the influence of adverse factors such as the temperature and the high-pressure gas impact on the fire-proof material when the vehicle new energy battery fire-proof coating material is damaged in a vehicle is reduced to the maximum extent.
Furthermore, a PLC and a PID are used for controlling a gas flow valve in the flaming device so as to control the flame temperature, and a gas flow valve in the pressure device is controlled so as to indirectly control the high-pressure impact force. The method can regulate the flame temperature and the high-pressure impact force at any time and in any time period.
Further, the control of the motion trail is programmed by adopting a demonstrator, the motion trail of the robot is controlled, so that the motion trail of flame in the flaming device and the motion trail of the pressure applying device are controlled, and the other robot is programmed to enable the tested fireproof material to be fixed in a certain space or move in a certain space according to a specified trail.
Furthermore, the temperature is collected in real time and fixed on the surface of the fireproof material by using a thermocouple, and a temperature collector is connected with the thermocouple for temperature collection. The real-time temperature of the surface of the fire-protecting material is monitored.
Furthermore, the pressure applying device utilizes an air compressor and an external connection device to design a pressure control system which can adjust the size and apply pressure at fixed time. Therefore, the impact force of the high-pressure gas which is unchanged or changed for many times in the process of one or more times of pressure application and pressure application of the fireproof material in any time period can be realized, and the mechanical property of the fireproof material is more comprehensively tested.
Compared with the prior art, the invention has the beneficial effects that: the performance and the safety of the fireproof material of the automobile power battery under the high-temperature environment or the high-pressure environment and even under the combined action of high temperature and high pressure are reduced to the maximum extent. The dynamic environment of the power battery in the new energy automobile when damaged is fully simulated.
