Specific embodiments

[0024] The following combines the accompanying drawings and gives embodiments to describe the present utility model in detail.

[0025] The present utility model provides a marine hydrogen filling device, which is applicable to the filling of 35 MPa hydrogen. As Figures 1-5 shown, the marine hydrogen filling device includes a cabinet-type housing, and a hydrogen filling pipeline, a nitrogen purging pipeline and an evacuation pipeline integrated in the cabinet-type housing.

[0026] A lifting ring is provided at the top of the cabinet-type housing to facilitate the movement of the device.

[0027] There are more than two types of filling ports on the hydrogen filling pipeline, and the filling ports are arranged at the upper part of the front of the cabinet-type housing; there are more than two output interfaces on the hydrogen filling pipeline, and the output interfaces are arranged at the lower part of the back of the cabinet-type housing and are connected to the external marine hydrogen storage cylinders.

[0028] The nitrogen purging pipeline is connected to the hydrogen filling pipeline and is used for the inerting of the hydrogen filling pipeline after hydrogen filling. Because the chemical property of nitrogen itself is very inactive, it is often used as a protective gas, and nitrogen is relatively common, so it is used as the purging gas source. The nitrogen input interface 28 of the nitrogen purging pipeline is arranged at the lower part of the back of the cabinet-type housing and is arranged side by side with the output interface of the hydrogen filling pipeline; evacuation pipelines are connected to both the hydrogen filling pipeline and the nitrogen purging pipeline, and can evacuate the hydrogen / nitrogen in the pipeline. The evacuation outlets of the two evacuation pipelines, namely the nitrogen evacuation interface 24 and the hydrogen evacuation interface 29, are arranged at the same height at the back of the cabinet-type housing.

[0029] In this embodiment, there are two types of filling ports, namely the TN1 filling port 2 and the TN5 filling port 1, on the hydrogen filling pipeline, which respectively correspond to the two commonly used hydrogen filling guns, TK16 and TK25, currently used for hydrogen filling.

[0030] A hydrogen pressure gauge 3 and a hydrogen pressure sensor 4 are provided on the hydrogen filling pipeline. The hydrogen pressure gauge 3 is installed on the upper part of the front of the cabinet-type housing and is located on the side of the filling port. Along the intake direction of the hydrogen filling pipeline, a filter I 22, a manual ball valve IV 8, a solenoid valve I 21, and a check valve I 19 are sequentially arranged; a combined manual and electric control method is used to control the device. The filter I 22 can ensure the purity of the supplied hydrogen. The manual ball valve IV 8 and the solenoid valve I 21 can realize the on / off of the hydrogen filling pipeline in both manual control and electric control modes. The check valve I 19 can ensure the gas flow direction and prevent gas backflow. In this embodiment, three output interfaces are provided at the rear end of the hydrogen filling pipeline, namely a first hydrogen output interface 25, a second hydrogen output interface 26, and a third hydrogen output interface 27, which are suitable for multi-channel hydrogen supply. A manual ball valve is provided at each output interface, namely ball valve I 16, ball valve II 17, and ball valve III 18: the on / off of each output interface can be controlled according to needs to select a reasonable output supply method and meet the usage requirements in different situations.

[0031] A nitrogen pressure gauge 5, a nitrogen pressure sensor II 6, and a nitrogen pressure sensor I 14 are provided on the nitrogen purge pipeline. The nitrogen pressure gauge 5 is installed on the upper part of the front of the cabinet-type housing and is located on the side of the filling port. Along the intake direction of the nitrogen purge pipeline, a filter II 15, a pressure reducing valve 11, a solenoid valve II 10, a needle valve I 7, and a check valve II 23 are sequentially arranged; the nitrogen pressure gauge 5 and the nitrogen pressure sensor II 6 are arranged before the pressure reducing valve 11, and a nitrogen pressure sensor I 14 is also provided after the pressure reducing valve 11 to monitor the gas pressure in the nitrogen purge pipeline in real time. When in use, the nitrogen source can be connected to the device through the nitrogen input interface 28, and the nitrogen is adjusted to the applicable pressure and flow range through the pressure reducing valve 11 so that the output nitrogen can meet the application requirements of different needs. The filter II 15 can ensure the purity of nitrogen; the check valve II 23 can ensure the gas flow direction and prevent gas backflow. The needle valve I 7 can manually control the on / off of the pipeline; the solenoid valve II 10 in the pipeline can be remotely controlled to open and close the pipeline through a program. The nitrogen purge pipeline adopts a series connection method of manual and electric control, which can effectively control the on / off of the pipeline and is more convenient for inerting the hydrogen filling pipeline after each marine hydrogen filling.

[0032] Needle valves are provided on both of the two evacuation pipelines, that is, a needle valve III 9 is provided on the nitrogen evacuation pipeline and a needle valve II 20 is provided on the hydrogen evacuation pipeline. By manually controlling the on / off of the needle valve III 9 / needle valve II 20, the start and stop of the evacuation pipeline are realized. When an abnormal situation occurs in the hydrogen / nitrogen supply pipeline, the gas in the pipeline can be discharged through the evacuation pipeline to ensure the safety of the device. Specifically, a check valve III 13 and a flow limiting valve 12 are also provided on the hydrogen evacuation pipeline.

[0033] In summary, the above is only the preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
