[0027] Example 1

[0028] like Figures 1-5 As shown, a safe and portable pressurized nitrogen filling vehicle includes a chassis 1 and a booster pump 2. At least one booster pump 2 driven by compressed air is installed on the inner bottom wall of the chassis 1. The booster pump 2 is connected to a high-pressure air inlet 3 and a high-pressure air outlet 5 through a high-pressure rigid pipe 4. The booster pump 2 is also connected in series with a pneumatic switch valve 11, an air source pressure regulating valve 9, and a driving air inlet 7 through a low-pressure hose 8. The booster pump 2, the high-pressure rigid pipe 4, and the low-pressure hose 8 are all located inside the chassis 1. The high-pressure air inlet 3, the high-pressure air outlet 5, the driving air inlet 7, the air source pressure regulating valve 9, and the pneumatic switch valve 11 are all located on the chassis 1.

[0029] In practical use, the setup of the housing 1 and the booster pump 2 allows the nitrogen filling truck's booster pipeline and connectors to be enclosed within the housing 1, eliminating the need for electrical control components and hydraulic oil. This improves the safety of the nitrogen filling truck and reduces manufacturing and maintenance costs.

[0030] In this embodiment, the booster pump 2 is provided with a booster pump inlet port 201, a booster pump outlet port 202, and a booster pump drive inlet port 203. The booster pump inlet port 201, the booster pump outlet port 202, and the booster pump drive inlet port 203 are all set to be unidirectional inflow or outflow.

[0031] In practical use, by setting the booster pump inlet 201, booster pump outlet 202 and booster pump drive inlet 203, the gas can be safely operated according to the set flow direction.

[0032] In this embodiment, the high-pressure rigid pipe 4 includes a first high-pressure rigid pipe 401, a second high-pressure rigid pipe 402, and a third high-pressure rigid pipe 403. The first high-pressure rigid pipe 401 is connected to a booster pump inlet 201 and a high-pressure inlet 3 at both ends, respectively. The second high-pressure rigid pipe 402 is connected to a booster pump outlet 202 and a high-pressure outlet 5 at both ends, respectively. One end of the third high-pressure rigid pipe 403 is connected to one port of a tee provided between the second high-pressure rigid pipe 402 and the high-pressure outlet 5 (i.e., the third high-pressure rigid pipe 403, the second high-pressure rigid pipe 402, and the high-pressure outlet 5 are connected through a tee), and the other end is connected to a high-pressure gauge 6.

[0033] In practical use, by setting the high-pressure gauge 6, the output pressure can be observed accurately in real time.

[0034] In this embodiment, the low-pressure hose 8 includes a first low-pressure hose 801, a second low-pressure hose 802, a third low-pressure hose 803, and a fourth low-pressure hose 804. The fourth low-pressure hose 804 is connected to a booster pump drive air inlet 203 and a pneumatic switch valve 11 at both ends. The second low-pressure hose 802 is connected to a pneumatic switch valve 11 and an air source pressure regulating valve 9 at both ends. The third low-pressure hose 803 is connected to an air source pressure regulating valve 9 and a drive pressure gauge 10 at both ends. The first low-pressure hose 801 is connected to an air source pressure regulating valve 9 and a drive air inlet 7 at both ends.

[0035] In practical use, by setting the air source pressure regulating valve 9, the driving air pressure gauge 10 and the pneumatic switch valve 11, the driving air pressure can be quickly switched on and off and adjusted, and the input driving air pressure can be observed accurately in real time.

[0036] In this embodiment, the chassis 1 includes a frame 101, a partition 102, and a control panel 103. The partition 102 can be detached from the frame 101, and the control panel 103 is fixedly connected to the frame 101.

[0037] In practical use, the setup of the frame 101, enclosure 102, and control panel 103 allows for the integration of nitrogen-filling vehicle components into the interior, achieving a compact and lightweight design while facilitating production assembly and subsequent maintenance.

[0038] In this embodiment, the control panel 103 is recessed and has corresponding mounting holes 1032. The pneumatic components and interfaces installed thereon will not protrude from the outer surface of the chassis 1. An operation mark 1031 is provided at the corresponding position next to the mounting holes 1032.

[0039] In practical use, by setting the mounting holes 1032 and the operation markings 1031, various pneumatic components on the nitrogen filling vehicle can be better fixed and protected, and the operation can be convenient.

[0040] In this embodiment, the bottom of the frame 101 is provided with casters 12, the back of the frame 101 is provided with a telescopic rod 13, and the top of the frame 101 is provided with a handle 14.

[0041] In practical use, the use of casters 12, telescopic rods 13, and handles 14 makes it easier to carry and move the nitrogen filling vehicle.

[0042] Working principle: During use, nitrogen is introduced into the high-pressure inlet 3 and flows into the booster pump 2 through the first high-pressure rigid pipe 401 connected to the booster pump inlet 201, waiting for pressurization. Then, compressed air is introduced into the drive air inlet 7 and flows into the air source pressure regulating valve 9 and the pneumatic switch valve 11 in sequence through the first low-pressure hose 801 and the second low-pressure hose 802. The other output end of the air source pressure regulating valve 9 is also connected to the drive air pressure gauge 10 through the third low-pressure hose 803. The drive air pressure gauge 10 can be used to observe the set drive air pressure after the pressure is adjusted by the air source pressure regulating valve 9 in real time. When the pneumatic switch valve 11 is opened, the drive air flows into the booster pump 2 through the fourth low-pressure hose 804 connected to the booster pump drive air inlet 203, driving the booster pump 2 to work and compress the incoming nitrogen. The pressurized nitrogen is discharged from the booster pump outlet 202 and flows into the second high-pressure rigid pipe 402. The pressurized nitrogen then flows through the second high-pressure rigid pipe 402. 2. The gas flows out to the high-pressure outlet 5 connected to the other end. The gas outlet interface 202 of the booster pump and the high-pressure outlet 5 are also connected to a high-pressure gauge 6 through a third high-pressure hard pipe 403. By adjusting the gas source pressure regulating valve 9, the driving gas pressure is changed, and the compression ratio of the booster pump 2 is controlled, thereby changing the pressure of the boosted nitrogen. The pressure of the boosted nitrogen can be observed in real time through the high-pressure gauge 6, so that the high-pressure outlet 5 outputs nitrogen that meets the gas pressure requirements. All of the above accessories are set in the inner cavity of the housing 1, and all accessories are pneumatic components that do not require electricity. The exterior of the housing 1 is also equipped with casters 12, telescopic rods 13 and handles 14 for easy carrying and movement. These settings solve the problems of the existing nitrogen filling truck's booster pipeline and connectors being exposed and requiring the application of some electrical control components and hydraulic oil to work properly, which causes the nitrogen filling truck to be unsafe to use and has high manufacturing and maintenance costs.

[0043] Example 2

[0044] like Figure 6 As shown, the distinguishing feature of this embodiment 2 from that of embodiment 1 is that: the high-pressure air inlet 3 of the nitrogen filling vehicle can be externally connected to the nitrogen source 15 through a suitable quick-connect cable; the driving air inlet 7 of the nitrogen filling vehicle can be externally connected to the driving air source 16 through a suitable quick-connect cable; the high-pressure air outlet 5 of the nitrogen filling vehicle can be externally connected to the energy storage device 17 through a suitable quick-connect cable; the nitrogen source 15 can output nitrogen at a minimum pressure of 2MPa; and the driving air source 16 drives the nitrogen filling vehicle to fill the energy storage device 17 with high-pressure nitrogen at a minimum pressure of 0.3MPa.

[0045] In practical use, by connecting the nitrogen source 15 and the driving air source 16 externally, the nitrogen-filling vehicle can be used normally under more different adaptable conditions, and is more environmentally friendly and energy-saving.
