[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] Figure 1 is a schematic diagram of a hydrogen storage device according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the hydrogen storage device may include: a controller 101, at least one displacement sensor 102, a solenoid valve 103, at least one hydrogen tank 104, and each hydrogen tank 104 is provided with a first stop valve 105; the first end of the first stop valve 105 can be connected to the first end of the hydrogen tank 104, and the second end of the first stop valve 105 can be connected to the first end of the solenoid valve 103; the second end of the solenoid valve 103 can be used as a free end for connecting to a hydrogenation device; the displacement sensor 102 can be provided on the first stop valve 105, and is used to collect the target opening of the first stop valve 105; the controller 101 can be connected to the at least one displacement sensor 102 and the solenoid valve 103, and is used to obtain the target opening of the first stop valve 105 collected by each displacement sensor 102, so as to obtain at least one target opening corresponding to the at least one displacement sensor 102, and control the opening of the solenoid valve 103 according to the at least one target opening.

[0045] The controller 101 may be a PLC (Programmable Logic Controller), a PAC (Programmable Automation Controller), an IPC (Industrial Personal Computer), a DCS (Distributed Control System) or an RTU (Remote Terminal Unit). The first stop valve 105 may be a manual stop valve. The displacement of the valve core of the first stop valve 105 is collected by the displacement sensor 102. The target opening of the first stop valve 105 can be determined based on the preset correspondence between the displacement of the valve core and the opening of the first stop valve 105. The solenoid valve 103 may be a through solenoid valve or a proportional solenoid valve.

[0046] It should be noted that the second end of the first stop valve 105 can be connected to the first end of the solenoid valve 103 through a hydrogen pipeline. The hydrogen pipeline can be a stainless steel pipeline, a copper pipeline or a carbon steel pipeline, etc. The target opening of the first stop valve 105 can be collected by the displacement sensor 102 set on the first stop valve 105. The controller 101 can determine whether each first stop valve 105 is in an open state according to the target opening of the first stop valve 105 collected by each displacement sensor 102 and the preset opening threshold. When it is determined that the target opening of each first stop valve 105 is greater than or equal to the preset opening threshold, it can be determined that each first stop valve 105 is in an open state, and the opening of the solenoid valve 103 is controlled to reach a preset opening range. For example, the opening range can be 85%-100% of the maximum opening of the solenoid valve 103. The solenoid valve 103 may include a coil and a valve body, and the valve body includes a valve core inside. The controller 101 can be connected to the coil, and the displacement of the valve core is controlled by controlling the current on the coil, so that the opening of the solenoid valve 103 reaches the preset opening range. Each hydrogen tank 104 may also be provided with a third stop valve; the first end of the third stop valve may be connected to the second end of the solenoid valve 103, and the second end of the third stop valve may be used to connect to a hydrogenation device.

[0047] Optionally, the controller 101 can also determine that the first stop valve 105 is not in an open state when it is determined that the target opening of any first stop valve 105 is less than a preset opening threshold, and display a prompt message to the user through a display device, wherein the prompt message is used to indicate that the first stop valve 105 is not open, so that the user can open the corresponding first stop valve 105 according to the prompt message.

[0048] Optionally, the first stop valve 105 can also be an automatic stop valve, and the controller 101 can be connected to the first stop valve 105 to obtain a control instruction input by the user through a preset interface. When the control instruction is determined to be an open instruction, the first stop valve 105 is controlled to open; when the control instruction is determined to be a close instruction, the first stop valve 105 is controlled to close.

[0049] The above technical solution, by arranging a controller, a solenoid valve and a displacement sensor in the hydrogen storage device, can effectively control the opening of the solenoid valve according to the target opening collected by the displacement sensor, reduce the user's operating errors in the process of filling or discharging hydrogen in the hydrogen storage device, avoid safety accidents of the hydrogen storage device, and effectively improve the safety of the hydrogen storage device.

[0050] Figure 2 According to this disclosure Figure 1 The embodiment shown is a schematic diagram of a hydrogen storage device, such as Figure 2As shown, each of the first stop valves 105 can be provided with a corresponding first signal light 106; the controller 101 can be connected to the at least one first signal light 106, and is used to send a first control signal to the first signal light 106 corresponding to the first stop valve 105 when it is determined that the target opening of the first stop valve 105 is greater than or equal to a preset opening threshold; the first signal light 106 can be used to light up when receiving the first control signal.

[0051] The first signal light 106 may be a light emitting diode (LED).

[0052] It should be noted that the opening state of the first stop valve 105 can be determined by the target opening and the preset opening threshold. The controller 101 can determine that the first stop valve 105 is in the open state when it is determined that the target opening of the first stop valve 105 is greater than or equal to the preset opening threshold, and send a first control signal to the first signal light 106 corresponding to the first stop valve 105. When it is determined that the first control signal is received, the first signal light 106 lights up to prompt the user that the first stop valve 105 is in the open state; the controller 101 can determine that the first stop valve 105 is not in the open state when it is determined that the target opening of the first stop valve 105 is less than the preset opening threshold, and send a third control signal to the first signal light 106 corresponding to the first stop valve 105. When it is determined that the third control signal is received, the first signal light 106 is in an extinguished state to prompt the user that the first stop valve 105 is not in the open state.

[0053] Optionally, Figure 2 For example, each of the first stop valves 105 can also be provided with a corresponding second signal light 107; the controller 101 can be connected to the at least one second signal light 107, and is used to send a second control signal to the second signal light 107 corresponding to the first stop valve 105 when it is determined that the target opening of the first stop valve 105 is less than the preset opening threshold; the second signal light 107 can be used to light up when receiving the second control signal.

[0054] The second signal light 107 may be an LED (Light Emitting Diode). The first signal light 106 may emit a different color from the second signal light 107. For example, the first signal light 106 may emit red light, and the second signal light 107 may emit other colors except red, that is, the second signal light 107 may emit green, yellow, or blue light, etc. The first signal light 106 may emit green light, and the second signal light 107 may emit other colors except green, that is, the second signal light 107 may emit red, yellow, or blue light, etc.

[0055] It should be noted that, when the controller 101 determines that the target opening of the first stop valve 105 is greater than or equal to a preset opening threshold, it can determine that the first stop valve 105 is in an open state, and send a first control signal to the first signal light 106 corresponding to the first stop valve 105. When the first signal light 106 determines that the first control signal is received, it lights up to prompt the user that the first stop valve 105 is in an open state; when it is determined that the target opening of the first stop valve 105 is less than the preset opening threshold, it is determined that the first stop valve 105 is not in an open state, and a second control signal is sent to the second signal light 107 corresponding to the first stop valve 105. When the second signal light 107 determines that the second control signal is received, it lights up to prompt the user that the first stop valve 105 is not in an open state.

[0056] Optionally, Figure 2 For example, the hydrogen storage device may also include: a temperature detection device T; the temperature detection device T may be arranged between the first stop valve 105 and the solenoid valve 103; the controller 101 may be connected to the temperature detection device T to obtain the current temperature collected by the temperature detection device T, and when it is determined that the current temperature is greater than or equal to the preset temperature threshold, control the opening of the solenoid valve 103 to decrease.

[0057] Among them, the temperature detection device T can be a thermocouple temperature sensor, a thermistor sensor, an infrared temperature sensor, a linear temperature sensor or a heat flow sensor, etc., and the preset temperature threshold can be the highest temperature corresponding to the optimal temperature range for hydrogen filling or discharging during the filling or discharging process of hydrogen. For example, the optimal temperature range for hydrogen filling or discharging can be 15°C-25°C, and the preset temperature threshold can be 25°C.

[0058] It should be noted that the temperature detection device T can be arranged on the hydrogen pipeline between the first stop valve 105 and the solenoid valve 103. The temperature detection device T collects the current temperature of the hydrogen flowing between the first stop valve 105 and the solenoid valve 103, and sends the collected current temperature to the controller 101. The controller 101 can control the opening of the solenoid valve 103 to decrease when it is determined that the current temperature collected by the temperature detection device T is received and the current temperature is greater than or equal to the preset temperature threshold.

[0059] Optionally, if the first stop valve 105 is an automatic stop valve, the controller 101 may be connected to the first stop valve 105 to control the opening of the first stop valve 105 to decrease when it is determined that the current temperature is greater than or equal to a preset temperature threshold.

[0060] Optionally, Figure 2 For example, the hydrogen storage device may also include: an air pressure detection device P; the air pressure detection device P may be arranged between the first stop valve 105 and the solenoid valve 103; the controller 101 may be connected to the air pressure detection device P, and be used to obtain the current air pressure collected by the air pressure detection device P, and when it is determined that the current air pressure is greater than or equal to the preset air pressure threshold, control the opening of the solenoid valve 103 to decrease.

[0061] The air pressure detection device P may be an air pressure sensor, a piezoresistive sensor, a capacitive sensor or a piezoelectric sensor, etc. It should be noted that the air pressure detection device P may be provided on the hydrogen pipeline between the first stop valve 105 and the solenoid valve 103, and is used to collect the current air pressure of the hydrogen flowing between the first stop valve 105 and the solenoid valve 103, and send the collected current air pressure to the controller 101. The controller 101 may control the opening of the solenoid valve 103 to decrease when it is determined that the current air pressure collected by the air pressure detection device P is received and the current air pressure is greater than or equal to the preset air pressure threshold.

[0062] Optionally, if the first stop valve 105 is an automatic stop valve, the controller 101 may be connected to the first stop valve 105 to control the opening of the first stop valve 105 to decrease when it is determined that the current air pressure is greater than or equal to a preset air pressure threshold.

[0063] The above technical solution, by setting the first signal light and the second signal light in the hydrogen storage equipment, can effectively prompt the user of the open state of the first stop valve, reduce user operation errors, and can effectively detect the temperature and air pressure during the hydrogen filling or discharge process through the temperature detection device and the air pressure detection device, avoid the occurrence of safety accidents of the hydrogen storage equipment, and is conducive to improving the safety of the hydrogen storage equipment.

[0064] Figure 3 According to this disclosure Figure 1The embodiment shown is a schematic diagram of another hydrogen storage device, such as Figure 3 As shown, each hydrogen tank 104 may also be provided with an explosion-proof device 108 ; a first end of the explosion-proof device 108 may be connected to a first end of the hydrogen tank 104 , and a second end of the explosion-proof device 108 may be connected to a first end of the first stop valve 105 .

[0065] It should be noted that the explosion-proof device 108 can release the hydrogen in the hydrogen tank 104 when the hydrogen pressure in the hydrogen tank 104 is greater than the rated pressure of the hydrogen tank 104, so as to ensure that the hydrogen pressure of the hydrogen tank 104 remains within a preset pressure range, which is beneficial to improving the safety of the hydrogen tank 104.

[0066] Optionally, Figure 3 For example, each hydrogen tank 104 may also be provided with a second stop valve 109 and a drain port 110 ; the first end of the second stop valve 109 may be connected to the second end of the hydrogen tank 104 , and the second end of the second stop valve 109 may be connected to the drain port 110 .

[0067] It should be noted that during long-term use, impurities or residual gas may accumulate inside the hydrogen tank 104, and the hydrogen tank 104 may be cleaned regularly or irregularly through the drain port 110 to ensure the purity of the hydrogen stored in the hydrogen tank 104. The residual pressure in the hydrogen tank 104 may also be released through the drain port 110 to ensure the safety of the operator when inspecting or maintaining the hydrogen tank 104.

[0068] Optionally, the hydrogen storage device may further include a power supply; the positive pole of the power supply may be connected to the positive power supply terminal of the controller 101, the positive terminal of the solenoid valve 103 and the positive terminal of the displacement sensor 102, and the negative pole of the power supply may be connected to the negative power supply terminal of the controller 101, the negative terminal of the solenoid valve 103 and the negative terminal of the displacement sensor 102.

[0069] It should be noted that the power supply can form a first circuit with the controller 101, the power supply can form a second circuit with the solenoid valve 103, and the power supply can form a third circuit with the displacement sensor 102. The power supply can supply power to the controller 101 through the first circuit, supply power to the solenoid valve 103 through the second circuit, and supply power to the displacement sensor 102 through the third circuit.

[0070] The above technical solution, by arranging a controller, a solenoid valve and a displacement sensor in the hydrogen storage device, can effectively control the opening of the solenoid valve according to the target opening collected by the displacement sensor, reduce the user's operating errors in the process of filling or discharging hydrogen in the hydrogen storage device, avoid safety accidents of the hydrogen storage device, and effectively improve the safety of the hydrogen storage device.
