In this way, when the piston of the oil cylinder 125 moves, the piston of the oil cylinder 125 can drive the first piston 122 and the second piston 124 to move, and thus can drive the pistons of the two hydrogen pressing cylinders to move simultaneously, so that the first hydrogen pressing cylinder 121 and the second hydrogen pressing cylinder 123 can alternately press hydrogen, and thus the hydrogen pressing efficiency can be improved. In some embodiments, the first hydrogen cylinder 121 and the second hydrogen cylinder 123 are both provided with a hydrogen inlet through which hydrogen enters the hydrogen cylinder and a hydrogen outlet through which hydrogen is compressed and then delivered to the hydrogen storage tank 110. Thereby, the compressed hydrogen gas can be stored into the hydrogen storage tank 110.
According to the embodiment of the present invention, the hydrogen pressurizing system 100 is configured by coaxially connecting the first piston 122 of the first hydrogen pressurizing cylinder 121, the second piston 124 of the second hydrogen pressurizing cylinder 123 and the piston of the oil cylinder 125. In this way, when the piston of the oil cylinder 125 moves, the piston of the oil cylinder 125 can drive the first piston 122 and the second piston 124 to move, and thus can drive the pistons of the two hydrogen pressing cylinders to move simultaneously, so that the first hydrogen pressing cylinder 121 and the second hydrogen pressing cylinder 123 can alternately press hydrogen, and thus the hydrogen pressing efficiency can be improved. Meanwhile, impact and noise generated instantly when the single cylinder reciprocates can be eliminated, so that the hydrogen pressing process is more stable.
According to some embodiments of the utility model, as shown in fig. 1, a plurality of hydrogen pressing assemblies 120 are arranged in parallel, so that a plurality of hydrogen pressing cylinders can press hydrogen simultaneously, thereby improving the hydrogen pressing efficiency. Of course, the arrangement of the plurality of hydrogen pressure assemblies 120 is not limited thereto, for example, in some embodiments, the plurality of hydrogen pressure assemblies 120 are arranged in series. In this way, the hydrogen can be compressed in multiple stages.

It should be noted that the valve body assembly 140 can not only control the operation of the plurality of hydrogen pressure assemblies 120, so that the plurality of hydrogen pressure assemblies 120 compress hydrogen gas alternately. Of course, the valve body assembly 140 may also control the first hydrogen cylinder 121 and the second hydrogen cylinder 123 to operate alternately. For example, under the action of the valve body assembly 140, when the first hydrogen cylinder 121 compresses hydrogen gas, the second hydrogen cylinder 123 stops compressing hydrogen gas; when the second hydrogen cylinder 123 compresses hydrogen gas, the first hydrogen cylinder 121 stops compressing hydrogen gas. The controller can control the valve body assembly 140 to act, so that the first hydrogen pressing cylinder 121 and the second hydrogen pressing cylinder 123 can be ensured to alternately compress hydrogen, and the operation stability of the hydrogen pressing system 100 can be improved.

According to some embodiments of the utility model, the solenoid valve is tribit four-way solenoid valve. For example, when the controller controls the first solenoid valve 141 to switch to the left position and the second solenoid valve 142 to switch to the right position, one of the hydrogen compression assemblies 120 compresses hydrogen, and the other hydrogen compression assembly 120 returns; conversely, when the controller controls the first solenoid valve 141 to switch to the right position and the second solenoid valve 142 to switch to the left position, one of the hydrogen compression assemblies 120 returns, and the other hydrogen compression assembly 120 compresses hydrogen. Thereby, the plurality of hydrogen compression assemblies 120 can alternately compress hydrogen gas.
According to some embodiments of the present invention, the hydrogen pressurizing system 100 further comprises a plurality of sensor assemblies, each sensor assembly detecting a piston position of a corresponding hydrogen pressurizing cylinder, each sensor assembly being in communication connection with the controller. For example, the hydrogen compression system 100 may include a first position sensor and a second position sensor spaced apart on the hydrogen compression assembly 120, the first position sensor being configured to detect a position of the first piston 122, and the second position sensor being configured to detect a position of the second piston 124.

The hydrogen compression system 100 further includes a cooling system 170, and the cooling system 170 is used for cooling the oil of the oil supply system 160. Thereby making it possible to stably operate the plurality of hydrogen compression assemblies 120. In addition, the cooling system 170 may form a circuit separately to cool the hydraulic oil.
