Problems solved by technology
[0003] In the prior art, by installing a hydrogen detector in the storage box outside the hydrogen storage tank, it is possible to detect whether the hydrogen gas leaks, but there are some problems in its use, the air flow in the storage box is slow, and the hydrogen gas The detector can only be installed on one side of the storage box. When it is directly detected by the hydrogen detector, the speed is relatively slow, and the hydrogen detector can only detect whether there is a hydrogen leak, and cannot judge the approximate location of the leak, which is inconvenient For maintenance, when the hydrogen detector has an abnormal alarm, it is impossible to judge whether the hydrogen detector is damaged or there is a gas leak, which is inconvenient to use

Embodiment Construction
[0031] The present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-13 Shown: a hydrogen storage tank gas leakage detection device for vehicles with hydrogen kinetic energy engines, including a storage box 1, a reset mechanism is provided on the upper end of the storage box 1, a detection mechanism is provided on the side of the reset mechanism, and the storage box 1 is There is a fixed-point sampling mechanism, and a comparison mechanism is set on one side of the fixed-point sampling mechanism.
[0032]The fixed-point sampling mechanism includes a servo motor 2 fixedly installed on one side of the upper surface of the storage box 1. The rotating end of the servo motor 2 is connected to a rotating rod 4 through a coupling 3. One end of the rotating rod 4 is equipped with a first rolling bearing 5, and the first rolling bearing 5, the lower end is equipped with a first support rod 6, the lower end of the first support rod 6 is fix...

The invention discloses a hydrogen storage tank air leakage detection device for a hydrogen powered engine vehicle. The device comprises a containing box, a reset mechanism is arranged at the upper end of the containing box, a detection mechanism is arranged on one side of the reset mechanism, a fixed-point sampling mechanism is arranged on the containing box, and a comparison mechanism is arranged on one side of the fixed-point sampling mechanism. The air leakage detection device has the beneficial effects that which position in the containing box leaks air can be judged, whether air leakageoccurs in the containing box or not can be rapidly detected, positioning can be rapidly conducted, maintenance is convenient, when outside air is detected, the outside air can enable air in a pipelineto circulate, and it can be guaranteed that the detection result is more accurate.
Description
technical field [0001] The invention relates to the technical field of hydrogen kinetic energy engine equipment, and more specifically, to a hydrogen storage tank air leakage detection device for a hydrogen kinetic energy engine vehicle. Background technique [0002] Hydrogen is an environmentally friendly energy source. The hydrogen kinetic energy engine generates electricity through hydrogen and drives the vehicle forward without producing harmful gases. However, hydrogen is also a flammable and explosive gas. When using hydrogen, in order to reduce potential safety hazards, it is necessary to check whether the hydrogen is Check for leaks. [0003] In the prior art, by installing a hydrogen detector in the storage box outside the hydrogen storage tank, it is possible to detect whether the hydrogen gas leaks, but there are some problems in its use, the air flow in the storage box is slow, and the hydrogen gas The detector can only be installed on one side of the storage bo...
