As a special place for filling hydrogen fuel into the hydrogen storage cylinders of hydrogen fuel cell vehicles, hydrogen filling stations have also developed to a certain extent.

[0003] In the daily use of the existing open trench type hydrogen pipeline trench of a hydrogen filling station, rainwater is usually accumulated inside during rainy days. The perennial soaking of rainwater is likely to cause a certain life erosion to the internal materials. Moreover, the rigidity and hardness of its surface support structure are usually insufficient, and it cannot bear the driving of large-tonnage vehicles on its surface. To solve the above technical problems, we have designed a hydrogen pipeline trench of a hydrogen filling station with a rainwater collection function. Content of the Utility Model

Second concrete cushions are arranged at the bottoms of the first hydrogen pipeline trench, the third hydrogen pipeline trench and the fourth hydrogen pipeline trench.

Second concrete cushions 22 are arranged at the bottoms of the first hydrogen gas pipe trench 1, the third hydrogen gas pipe trench 6 and the fourth hydrogen gas pipe trench 7.

[0022] Please refer to Figure 2 , a concrete support 20 is arranged at the bottom of the catch basin 9, and a first concrete cushion 13 is cast at the bottom of the concrete support 20. By arranging the first concrete cushion 13 and the second concrete cushion 22, the bottom of the catch basin 9 and the bottom of the first hydrogen gas pipe trench 1 can be supported, thereby improving the support stability of its main body.

[0023] Please refer to Figure 2 , a second reinforcing rib 16 is arranged through the left side of the catch basin 9, and a reinforcing tie bar 15 is sleeved on the surface of the second reinforcing rib 16. By arranging the reinforcing tie bar 15 and the second reinforcing rib 16, the strength of the catch basin 9 can be enhanced by means of mutual winding.

[0024] Please refer to Figure 2 , a steel grid 17 is laid on the top of the catch basin 9. By arranging the steel grid 17, a certain blocking and intercepting effect can be provided, which can effectively prevent personnel or foreign objects from falling, thereby improving the safety during the operation of the entire hydrogen filling station. A reinforced cover plate 10 is arranged through the top of the first hydrogen gas pipe trench 1.

[0027] During use, after the rainwater enters the inner cavity of the first hydrogen gas trench 1, the filter screen 14 will intercept the large-particle impurities contained therein to prevent them from entering the inner cavity of the first hydrogen gas trench 1. Then, after the liquid is guided by the guiding liquid delivery pipe 8 in the inner cavity of the first hydrogen gas trench 1, the one-way filter screen 18 intercepts the small-particle impurities, and then enters the inner cavity of the water collection pool 9, thus completing the guiding and discharging of the accumulated rainwater, preventing it from accumulating in the trench for a long time and corroding the surface of the pipeline.
