The application relates to a wading protection system, a wading protection method and a vehicle, relates to intelligent cabin technology of a vehicle, and the wading protection system comprises a wading detection module, an air path control module, a floating water airbag, a gas generating module and a main control module; the floating water airbag is connected with the gas generating module in an air path, and is connected with an engine exhaust port in an air path through the air path control module; the engine exhaust port is connected with a vehicle exhaust port in an air path through the air path control module; the air path control module is used for controlling the on-off of the air path among the floating water airbag, the engine exhaust port and the vehicle exhaust port; the main control module is electrically connected with the wading detection module, the air path control module and the gas generating module respectively, and is used for controlling the air path control module or the gas generating module to inflate the floating water airbag according to a wading height detected by the wading detection module. Compared with the existing structure sealing scheme, the application can cope with more complex wading conditions, and improves the wading protection effect.

The present invention discloses a water conservancy pipeline quality detection device, which relates to the technical field of water conservancy engineering, and comprises a frame, air bags are connected to both ends of the frame, and the frame is also connected to an air pump that can inflate the air bags. When the air bags are filled with gas, the air bags, the frame and the pipeline cooperate with each other to enclose and form a detection space; the frame is connected to an air inlet pipe, the air pump and the air inlet pipe are connected, an air hole is opened in the air inlet pipe, and a sealing plug that can block the air pipe is slidably connected in the air inlet pipe. The device is easy to operate, can detect the air tightness of any position in the pipeline, is not limited by the diameter of the pipeline, has an intuitive detection effect, can realize rapid detection of pipeline quality, and has high detection accuracy.

The utility model relates to a kind of hydrogen storage and supply device, system, the device includes storage pipeline and the first storage tank and second storage tank connected therewith, and power device and adjusting device. The first storage tank stores water, it has gas storage mode and gas supply mode. Under gas storage mode, the hydrogen gas of hydrogen production equipment is received and stored by the first storage tank, and water is transferred to the second storage tank. Under gas supply mode, the water of second storage tank is transferred to the first storage tank by power device to discharge hydrogen gas for gas supply. Adjusting device is used to adjust the flow or exhaust volume of hydrogen gas received by the first storage tank. The gas storage and gas supply process of the system does not need to use expensive hydrogen compressor, and is safer, lower power consumption. And by setting adjusting device, the flow or exhaust volume of hydrogen gas received by the first storage tank can be adjusted, so that the pressure of each storage tank and the entire system can be kept constant, the hydrogen pressure of pipe network is stable, and the pressure cycle fluctuation is reduced.
