Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cell detection equipment, in particular to a hydrogen fuel cell spraying experimental device. Background Art

[0002] With the popularization of new energy vehicles since 2008, hydrogen-powered vehicles have emerged one after another. Compared with traditional fuel and electric vehicles, hydrogen-powered vehicles offer advantages such as renewability, high efficiency, low emissions, environmental friendliness, long driving range, high safety, and readily available materials. These advantages are likely to become a major research and development direction for future vehicles. Hydrogen fuel cell engines, in particular, require rainproof testing before installation.

[0003] Application No. 202221522435.9 discloses a fuel cell hydrogen rain test box, which places the fuel cell in a fixed box, drives the mobile box to move through a moving mechanism, and arranges a water spray pipe on the lower side of the mobile box. The water spray pipe sprays the fuel cell as the mobile box moves, thereby effectively conducting a spray test on the fuel cell.

[0004] However, although the existing technology uses a mobile box to drive the water pipe to move and spray, thereby increasing the spraying range, the position of the fuel cell is fixed. The water pipe can only spray the battery when it is moved near the fuel cell. It cannot effectively spray the battery when it is far away from the battery, resulting in an inability to continuously spray the fuel cell; and the amount of water sprayed by the water pipe is the same, which cannot simulate the conditions of different rainy days, resulting in a deviation between the experimental results and the actual use results, affecting the fuel cell detection results. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a hydrogen fuel cell spraying experimental device to solve the problems of inability to spray continuously and stably and inability to simulate different rainy conditions affecting the experimental results.

[0006] Based on the above-mentioned purpose, the utility model provides a hydrogen fuel cell spray experimental device, including a laboratory, a water pool is arranged at the bottom of the laboratory, a partition is installed on the upper side of the water pool, a sliding track is installed on the partition, and a placement vehicle for placing the hydrogen fuel cell is slidably arranged on the sliding track; a water inlet main pipe is installed on one side of the top of the laboratory, a water pump is installed at the water inlet end of the water inlet main pipe, one end of the water inlet main pipe is connected to a first water branch pipe and a second water branch pipe through a multi-joint, the first water branch pipe and the second water branch pipe are detachably installed on the top of the laboratory, a plurality of groups of atomizing nozzles are equidistantly installed on the first water branch pipe, and a plurality of groups of spraying nozzles are equidistantly installed on the second water branch pipe.

[0007] A further improvement is that the first water distribution pipe and the second water distribution pipe are arranged in parallel, and the first water distribution pipe and the second water distribution pipe adopt a wave-shaped structure.

[0008] A further improvement is that the sliding track is provided corresponding to the first water distribution pipe and the second water distribution pipe.

[0009] A further improvement is that solenoid valves are installed at the water inlet ends of the first water distribution pipe and the second water distribution pipe, and manual valves are installed at the drainage ends of the first water distribution pipe and the second water distribution pipe.

[0010] A further improvement is that a pressure sensor is installed on the water inlet main pipe.

[0011] A further improvement is that a plurality of water guide grooves are provided on the surface of the partition, the water guide grooves are provided on both sides of the sliding vehicle track, and through holes are provided in the water guide grooves.

[0012] A further improvement is that a filter is installed in the pool, a circulating water pipe is installed on one side of the pool, and one end of the circulating water pipe is connected to the water inlet end of the water pump.

[0013] The beneficial effects of the present utility model are as follows: an atomizing nozzle and a spraying nozzle are correspondingly arranged on the first water branch pipe and the second water branch pipe, and different water branch pipes are switched to use different nozzles for spraying water. The atomizing nozzle simulates light rain spraying, and the spraying nozzle simulates heavy or medium rain spraying. In addition, the first water branch pipe and the second water branch pipe are arranged in a wave shape, which increases the spraying range and ensures the comprehensiveness of the spraying, thereby making the experimental process more in line with actual usage and improving the accuracy of the experimental results.

[0014] By setting up a sliding track, the fuel cell is placed on the placement vehicle and moved along the sliding track. The sliding track is set corresponding to the water distribution pipe. The nozzle on the water distribution pipe sprays the fuel cell throughout the movement of the placement vehicle, thereby improving the comprehensiveness of the spray. In addition, the movement of the placement vehicle simulates the movement of the fuel cell during actual use, making the experimental simulation more in line with reality and further improving the accuracy of the experimental results.

The two water pipes 9 have a wavy structure. Solenoid valves 12 are installed at the water inlet ends of both the first and second water pipes 8, 9, and manual valves 13 are installed at the discharge ends. The manual valves 13 are used when the first and second water pipes 8, 9 are disassembled.

The pressure sensor 14 monitors the pressure within the water pipe. The water pump 7 is PWM-controlled by the external PLC controller, adjusting its speed to control the pressure within the pipe. As the pressure within the pipe changes, the amount of water sprayed is controlled.
