[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] like Figure 1-5As shown, a crash box of a hydrogen filling station includes a box body 1, a correction ring 8 and a top plate 7. The box body 1 is provided with a accommodating groove with an upward opening, a notch 2 communicating with the accommodating groove is provided at the lower end of the box body 1, and a reserved opening 3 communicating with the accommodating groove is provided at the top of the side of the box body 1. The accommodating groove has four corners, and each of the four corners is provided with a pipe 4 passing through the upper and lower parts. The lower end of the correction ring 8 is embedded in the pipe 4, and the top plate 7 is fixedly connected to the upper end of the box body 1; the electrical equipment required for hydrogenation is installed in the box body 1, and the power and gas supply are connected to the pre-buried underground joint through the notch 2, and the terminal hydrogenation gun is connected to the adapter of the electrical equipment through the reserved opening 3. A screen can be installed on the side of the box body 1 , which is convenient for information display during hydrogen refueling and payment after hydrogen refueling; the reserved opening 3 is located at the top of the side of the box 1, which is convenient for hanging the gas pipe of the hydrogen gun, avoiding the gas pipe from being exposed to the impact height, and preventing the gas pipe from being torn off when an impact occurs; at the construction site, four sets of steel bars need to be reserved on the ground. After the steel bars are tied separately, the pipes 4 at the four corners of the accommodating groove of the box 1 are inserted into the tied steel bars, and then a circle of sealant is applied at the junction of the pipe 4 and the ground, and concrete can be poured into the pipe 4 to form four reinforced concrete anti-collision columns at the four corners of the box 1 to protect the safety of the electrical equipment in the box 1.

[0021] In the above embodiment, the middle part of the correction ring 8 is a filling hole 10 for pouring concrete. A plurality of positioning holes 11 are provided around the filling hole 10. The plurality of positioning holes 11 are arranged in a circular array. The steel bars can be straightened and then passed through the positioning holes 11 to ensure that the steel bars are evenly distributed and the steel structure is stable after being tied with the steel bars. This ensures that the strength of the reinforced concrete column after being formed meets the anti-collision requirements. The outer contour of the upper end of the correction ring 8 is a regular hexagon. When the positioning hole 11 of the correction ring 8 is inserted into the steel bar, the outer contour of the regular hexagon facilitates the clamping of the wrench. The side of the box body 1 is provided with a vent 5 to provide a heat dissipation channel for the electrical equipment in the box body 1. The front end of the box body 1 is provided with a box door 6 connected to the accommodating groove to facilitate the installation and maintenance of the electrical equipment in the box body 1. The bottom of the top plate 7 is provided with a groove 9. The upper end of the box body 1 is embedded in the groove 9 to provide rain protection for the electrical equipment in the box body 1. After the concrete pouring is completed, the connection between the top plate 7 and the box body 1 can be closed by welding to prevent the steel bars in the reinforced concrete column from being corroded.

[0022] Description of the working method of this utility model:

[0023] During the construction phase of the hydrogen station, the pipelines and lines are directly buried according to the layout of the architectural drawings. At the same time, vertical steel bars exposed to the ground are reserved underground. The distribution of the steel bars is adapted to the positioning holes 11 of the correction ring 8 of the device. Put the multiple groups of steel bars on the ground into the correcting rings 8 respectively, put the correcting rings 8 on the top of the steel bars, and then tie the steel bars; the steel bars after tying form a stable steel structure, and then take out the correcting rings 8 from the top of the steel bars, and then put the entire box 1 on the steel structure from top to bottom through the pipe 4. After the box 1 is against the ground, put the correcting rings 8 through the positioning holes 11 to the upper end of the steel structure, and then align the lower end of the correcting rings 8 and embed it into the pipe 4. At this point, the positioning of the box 1 is completed; apply a circle of sealant on the connection between the pipe 4 of the box 1 and the ground, and then pour concrete into the pipe 4 through the filling hole 10; use the C50 strength grade formula to mix and make concrete, pour the concrete into the pipe 4 in layers, and use an iron rod to tamp each layer to ensure the compactness of the concrete. After the concrete solidifies, water it according to the prescribed maintenance standards to ensure that the strength grade of the reinforced concrete after forming meets the requirements. After the reinforced concrete columns are completed, the exposed steel bars on the upper ends of the correction rings 8 are cut, and then the top plate 7 is installed and welded. The electrical equipment and pipelines in the box body 1 are connected through the box door 6, and the device is ready for use. During the operation of the hydrogen refueling station, if the box body 1 is hit by a vehicle, the reinforced concrete columns built into the four corners of the box body 1 can withstand the very large impact force, playing a vital role in protecting the electrical equipment and pipelines in the box body 1, thereby ensuring the safety of the hydrogen refueling station.
