Problems solved by technology

[0004] However, it takes a lot of time and production cost to test the fuel cell engine in the actual environment, so it is necessary to use an environmental chamber to simulate various environments to complete the test verification, and finally put it into actual use
[0005] The safety system and laboratory conditions of the current fuel cell engine test have the disadvantages of low safety, inability to effectively guarantee the safety of test personnel, equipment and laboratory, poor environmental control and low test efficiency, and the environmental chamber does not have imitation sparks And explosion-proof function, can not meet the safety and reliability of the fuel cell engine in the environmental chamber to complete the test items of performance and reliability in various simulated environments

Embodiment 1

[0043] This embodiment proposes a safety system for a fuel cell engine test, such as figure 1 As shown, including an environmental chamber for housing the fuel cell engine and allowing it to be tested in the environmental chamber. Various test environments can be provided in the environmental chamber to test the operating performance of the fuel cell engine in various environments; to ensure the safety of its use, the fuel cell engine that has passed various test conditions and is operating normally can be put into practical use. Using.

[0044] Specifically, a pressure relief device 4 and an air exhaust port 8 are provided on the top of the environmental box for exhausting gas. When there is an abnormal gas situation in the environmental box, there is a lot of gas in it, and the air pressure is high, it needs to be discharged from the pressure relief device 4 or the air outlet 8, so that it will not explode, so as to ensure the air pressure in the environmental box normal. ...

Embodiment 2

[0061] In this embodiment, a control method for a safety system for a fuel cell engine test is proposed, including the safety system for a fuel cell engine test in Embodiment 1.

[0062] Specifically, such as Figure 4 As shown, the control method of the safety system of the fuel cell engine test also includes four-level prevention and control: first-level prevention and control, second-level prevention and control, third-level prevention and control, and fourth-level prevention and control. Among them, the first level of prevention and control, when the first sensor 1 detects that the hydrogen concentration in the environmental chamber reaches 20% of the lower limit of hydrogen ignition, the control system controls the alarm to send out an audible and visual alarm, and the test personnel can remotely view and verify it through the camera. Whether there is hydrogen leakage or other failures occur.

[0063] Secondary prevention and control, when the first sensor 1 detects that...

Abstract

The invention discloses a safety system for a fuel cell engine test and a control method thereof, and belongs to the technical field of engine tests. The safety system for the fuel cell engine test comprises an environment box used for placing a fuel cell engine, and a pressure relief device and an exhaust outlet being arranged at the top end of the environment box and used for exhausting gas; a spiral finned tube heater, arranged in the environment box and used for heating the temperature in the environment box; a control system, used for receiving the signal and sending a control signal; a monitoring system, in signal connection with the control system and used for charging nitrogen into the environment box or starting the air outlet; and a fire extinguishing system, in signal connectionwith the control system and used for starting the high-pressure water mist spray head at the top end of the environment box so as to spray water into the environment box to extinguish fire. The safety system has the advantage that the fuel cell engine can safely and reliably complete test items in various simulation environments in the environment box.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to a safety system for fuel cell engine testing and a control method thereof. Background technique [0002] As an important technical direction of new energy vehicles, fuel cell engine has the characteristics of no mechanical loss in the reaction process, high energy conversion rate, only electricity, heat and water, stable operation and low noise, and is called "the ultimate environmental protection engine"; The development of fuel cell energy vehicles is of great significance to stabilizing energy supply, improving energy structure, developing low-carbon transportation, enhancing international competitiveness and technological innovation, and maintaining the sustainable development of the automobile industry. [0003] A fuel cell engine is a power generation device that directly converts hydrogen and oxygen into electrical energy through electrochemical reactions, but its w...
