Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage and utilization, and in particular to a hydrogen storage device and system for a hydrogen energy lighting tower. Background Art

[0002] A hydrogen lighting tower is a lighthouse that uses hydrogen energy to provide lighting. Due to the environmental protection, safety and renewability of hydrogen energy, in a hydrogen energy system, hydrogen can be used as fuel and fuel cells to generate energy through combustion and electrochemical reactions to drive the lighting equipment of the lighthouse.

[0003] Lighthouses are commonly used in the field of navigation, mainly to provide navigation and marking for ships. Lighting lighthouses are usually located on coastlines, ports, waterways, reefs, etc., using towering towers and lighting equipment to indicate the direction and safety of ships.

[0004] Since lighthouses are used for ship navigation, they need to be able to provide long-term, continuous and stable lighting. Existing hydrogen storage devices mostly use a single gas cylinder with a small volume. When used in a lighting lighthouse environment, it is difficult to ensure a stable supply of hydrogen energy. At the same time, the environment of lighthouses located on the coast is changeable, and it is difficult for staff to replenish hydrogen energy in a timely manner in bad weather, which increases the need for endurance of hydrogen storage devices.

The bottle pressure control submodule is used to cooperate with the valve control submodule to control the air pressure in the hydrogen storage bottle group 1.

The valve control submodule is electrically connected to the drive motor connected to one end of the valve stem 302, the pressure reducing valve 201, the electric control valve 203 and the outlet valve 402;

[0047] A hydrogen storage system for a hydrogen energy lighting tower includes the following specific steps:

[0048] Step 1: When the hydrogen storage bottle group 1 is not in use, the pressure gauges on the top of the main gas bottle 101 and the auxiliary gas bottle 102 are used to determine the pressure change. The pressure detection submodule records the pressure data in real time, and identifies whether the main gas bottle 101 and the auxiliary gas bottle 102 have gas leakage and expansion when not in use according to the pressure change. The gas in the hydrogen storage bottle group 1 is recovered and processed in time to reduce the waste of hydrogen energy;

[0049] It should be added that the method for processing gas recovery is to adjust the working state of the control valve 3, specifically:

[0050] The connection between the air guide elbow 202 and the valve body 301 is inclined, the angle between the air guide elbow 202 and the vertical plane is 30°, the inner wall of the larger diameter side of the funnel-shaped through hole 304 is set at an angle of 60° with respect to the horizontal line, the inner wall of the smaller diameter side of the through hole 304 is perpendicular to the horizontal line, and the air outlet conduit 401 is vertically arranged with respect to the bottom of the valve body 301;

[0051] The through hole 304 is vertically arranged with respect to the inner wall of the valve body 301, one side of the through hole 304 is in contact with the inner wall of the valve body 301, and the other side of the through hole 304 is connected with the air outlet conduit 401, so that the regulating valve 3 is in a closed state. The closed state of the regulating valve is set as state 1, the valve core 303 is rotated 180° clockwise from state 1 to state 2, and the valve core 303 is rotated 30° clockwise or counterclockwise from state 1 to state 3;

[0052] When the regulating valve 3 is in state 1, the flow of gas in the hydrogen storage bottle group 1 is blocked and the gas supply is stopped;

[0053] When the regulating valve 3 is in state 2, the main gas cylinder 101 and the auxiliary gas cylinder 102 are connected to the regulating valve 3 through the gas pipeline 2 at the same time, and more hydrogen is guided out of the gas outlet pipeline 4 through the regulating valve 3;

[0054] When the regulating valve 3 is in state three, one of the main gas cylinder 101 and the auxiliary gas cylinder 102 is connected to the regulating valve 3 through the gas guide pipe 2, and a small amount of hydrogen is guided out of the gas supply from the gas outlet pipe 4 through the regulating valve 3.

[0055] Step 2: When the air pressure of the main gas cylinder 101 and the auxiliary gas cylinder 102 has not leaked before use, the valve regulating submodule controls the rotation angle of the valve core 303 to control the gas supply of the main gas cylinder 101 and the auxiliary gas cylinder 102 to supply energy to the hydrogen energy lighting tower. Hydrogen energy is environmentally friendly and produces low noise through electrochemical reactions, which can meet the lighting needs of various occasions. At the same time, during the gas supply process, it is determined whether the main gas cylinder 101 and the auxiliary gas cylinder 102 are leaking. The hydrogen energy lighting tower is supplied with gas and energy through the hydrogen storage bottle group 1, providing double protection to meet the normal use of the hydrogen storage device under economic conditions.

[0056] Step 1 also includes the following specific steps:

[0057] Step 1-a: When hydrogen is stored inside the hydrogen storage bottle group 1, the pressure gauges on the top of the main gas bottle 101 and the auxiliary gas bottle 102 are used, and the pressure detection submodule monitors and records the internal pressure values ​​of the main gas bottle 101 and the auxiliary gas bottle 102 in real time. The pressure values ​​are transmitted to the pressure detection submodule, and the data comparison submodule determines the changes in the pressure in the main gas bottle 101 and the auxiliary gas bottle 102;

[0058] Specifically, in the data comparison submodule, the air pressure values ​​of the main gas cylinder 101 and the auxiliary gas cylinder 102 in the normal state are set to p, and the air pressure detection submodule detects in real time that the air pressure value of the main gas cylinder 101 is a, and the air pressure value of the auxiliary gas cylinder 102 is b;

[0059] When p is equal to a and b, it means that the hydrogen storage bottle group 1 is in a stable state and can be used normally;

[0060] When p is greater than or less than a, and p is equal to b, it indicates that the main gas cylinder 101 has a problem of high temperature expansion or damage and leakage, and the pressure reducing valve 201 on the top of the main gas cylinder 101 is closed, and gas can only be supplied through the auxiliary gas cylinder 102;

[0061] When p is greater than or less than b, and p is equal to a, it indicates that the auxiliary gas cylinder 102 has a problem of high temperature expansion or damage and leakage. The pressure reducing valve 201 on the top of the auxiliary gas cylinder 102 is closed, and gas can only be supplied through the main gas cylinder 101;

[0062] Step 1-b: When the state of the hydrogen storage bottle group 1 is stable, the valve control submodule is controlled to rotate the control valve 3 to state 2, and the outlet valve 402 is closed at the same time to block the hydrogen from flowing out of the outlet duct 401, and the pressure reducing valve 201 and the electric control valve 203 on the top of the main gas bottle 101 and the auxiliary gas bottle 102 are opened, so that the main gas bottle 101 and the auxiliary gas bottle 102 are connected through the two groups of gas guide pipes 2 and the control valve 3, and the gas of one of the main gas bottle 101 and the auxiliary gas bottle 102 is injected into the other gas bottle for pressurization. After the quantitative gas is injected, the control valve 3 is closed to state 1 to block the connection between the main gas bottle 101 and the auxiliary gas bottle 102, and the pressure changes of the main gas bottle 101 and the auxiliary gas bottle 102 are recorded by the pressure detection submodule, and the data comparison submodule compares the pressure data, and the integrity of the main gas bottle 101 and the auxiliary gas bottle 102 is self-checked to avoid the potential safety hazards caused by the cracks in the gas bottle during the later use, so as to ensure the safety of the subsequent use of the gas bottle;

[0063] Specifically, when the air pressure of one of the main gas cylinder 101 and the auxiliary gas cylinder 102 increases steadily, the pressure gauge cooperates with the pressure detection submodule to record the value of the pressure change in real time. When the pressure value of the pressurized gas cylinder increases and then remains stable, it indicates that the pressurized gas cylinder is intact. The regulating valve 3 is turned to state 2 again, and the outlet valve 402 is kept closed to discharge the gas in the pressurized gas cylinder into the other gas cylinder. The pressure in the hydrogen storage cylinder group 1 is observed in real time again through the pressure detection submodule. When the pressure of the other gas cylinder increases and then remains stable, it indicates that the main gas cylinder 101 and the auxiliary gas cylinder 102 are both intact.

[0064] When the gas pressure of one of the main gas cylinder 101 and the auxiliary gas cylinder 102 increases and then decreases, the fine cracks in the gas cylinder will rupture and leak, and the pressure reducing valve 201 will be controlled to stop injecting gas and pressurizing the ruptured gas cylinder, and the staff will be quickly informed of the damage to the cylinder through the safety alarm submodule.

[0065] Step 1-b includes the following specific steps:

[0066] Step 1-b1: When the gas from one of the main gas cylinder 101 and the auxiliary gas cylinder 102 is injected into the other gas cylinder, the gas pressure in the main gas cylinder 101 and the auxiliary gas cylinder 102 remains unchanged, then there is a blockage problem in the gas guide pipe 2 or the control valve 3, and the gas is difficult to flow. It is necessary to detect the specific blocked part and solve the internal blockage at the same time to ensure the smooth flow of hydrogen. The control valve 3 is kept in state 2, and the specific location of the blockage is determined by the pressure change caused by the gas flow, so as to deal with the blockage in time and avoid damage caused by high-pressure gas blockage;

[0067] Specifically, the electric control valves 203 on the main gas cylinder 101 and the auxiliary gas cylinder 102 are closed successively, and the gas outlet valve 402 is opened at the same time, and the hydrogen in one of the main gas cylinder 101 and the auxiliary gas cylinder 102 is discharged from the gas outlet pipeline 4 through the gas guide pipeline 2 and the regulating valve 3, and the changes in the pressure gauge values ​​on the main gas cylinder 101 and the auxiliary gas cylinder 102 are recorded through the gas pressure detection submodule;

[0068] If the gas pressure value of one of the main gas cylinder 101 and the auxiliary gas cylinder 102 decreases steadily, it means that there is no blockage in the gas pipeline 2 and the regulating valve 3 on one side of the main gas cylinder 101 or the auxiliary gas cylinder 102, and the blockage problem occurs in the gas pipeline 2 on the other gas cylinder;

[0069] When the air guide line 2 is blocked, the air outlet valve 402 is closed, the pressure reducing valve 201 and the electric control valve 203 in the blocked air guide line 2 are opened, and the cylinder gas on the unblocked side of the air guide line 2 is injected into the blocked air guide line 2 through the pressure reducing valve 201, and the blocked air guide line 2 is dredged with high pressure. The air outlet valve 402 is opened, and the cylinder gas on the unblocked side of the air guide line 2 is ejected from the air outlet line 4 through the regulating valve 3 through the pressure reducing valve 201, so that a low-pressure environment is generated on the inner wall of the blocked air guide line 2, and the blocked air guide line 2 is dredged with low pressure.

[0070] When the regulating valve 3 is in state 2, the pressure detection submodule monitors in real time that the air pressures of the main gas cylinder 101 and the auxiliary gas cylinder 102 have not changed. At the same time, when the electric control valve 203 in the gas guide line 2 is opened, the valve control submodule senses that the air pressure in the electric control valve 203 increases, indicating that the regulating valve 3 is blocked.

[0071] When the regulating valve 3 is blocked, the two groups of air guide pipes 2 on the top of the hydrogen storage bottle group 1 are opened to inject hydrogen into the valve body 301. At the same time, the valve regulating submodule drives the valve core 303 to rotate slowly through the valve stem 302 by the driving motor, and the air pressure monitoring submodule monitors the air pressure of the hydrogen storage bottle group 1 in real time. When the air pressure in the hydrogen storage bottle group 1 steadily decreases, it means that the regulating valve 3 is unblocked, and the through hole 304 in the valve core 303 is cleaned by gas squeezing, so that the device can autonomously clean the blockage in the pipeline and extend the service life of the device.

[0072] Step 1-b2: When the air pressure in the main gas cylinder 101 suddenly increases, the air pressure of the hydrogen storage bottle group 1 is recorded by the air pressure detection submodule, and the data is compared by the data comparison submodule, and it is concluded that the air pressure in the auxiliary gas cylinder 102 is relatively low, and the internal air pressure is less than the air pressure in the full-filled state, and it has storage capacity. By opening the pressure reducing valve 201 and the electric control valve 203, the regulating valve 3 is turned to state two, and the outlet valve 402 is closed at the same time, the main gas cylinder 101 and the auxiliary gas cylinder 102 are connected through the air guide pipe 2 and the regulating valve 3, and the expanded gas in the main gas cylinder 101 is discharged into the auxiliary gas cylinder 102. When the air pressure in the auxiliary gas cylinder 102 suddenly increases, the same is true to ensure that the air pressure of the hydrogen storage bottle group 1 is stable, the storage quality of hydrogen is guaranteed, and the waste of hydrogen energy is reduced.

[0073] While transferring hydrogen, the regulating valve 3 is controlled by cooperating with the valve regulating submodule through the pressure control submodule in the bottle, and the regulating valve 3 is rotated to state two. The driving motor drives the valve core 303 to rotate through the valve stem 302, and the valve core 303 is rotated clockwise or counterclockwise by 15° to adjust the aperture size of the communication between the through hole 304 and the gas guide elbow 202. According to the full-filled gas pressure value of the gas cylinder, the gas pressure of the gas cylinder introduced by the gas is detected in cooperation with the gas pressure detection module. When the gas pressure of the gas cylinder introduced by the gas is close to the full-filled gas pressure value, the angle of the valve core 303 is gradually deflected to slow down the flow of gas, so as to avoid damage to the gas cylinder caused by excessive gas pressure. After the gas cylinder reaches the full-filled gas pressure value, the regulating valve 3 is closed to state one. When the pressure of the expanded gas cylinder continues to increase through the pressure detection submodule, the valve regulating submodule opens the pressure relief port on the pressure reducing valve 201 to relieve the pressure, thereby improving the safety of the device and avoiding safety hazards caused by continuous expansion of the gas cylinder due to heat.

[0074] Step 2 includes the following specific steps:

[0075] Step 2-a: When the hydrogen energy lighting tower works in an environment with high visibility, the required lighting power is low, and the required hydrogen energy is less. The valve core 303 is rotated to rotate the regulating valve 3 to state three, and the valve core 303 in state three is deflected to adjust the aperture size of the through hole 304 and the air guide elbow 202, and the supply rate of hydrogen energy is changed and adjusted to supply energy to the lighting tower, so as to avoid excessive supply of hydrogen energy and waste of hydrogen energy, and at the same time enhance the endurance of the device;

[0076] Adjust the connectivity of the valve core 303 in state three of the regulating valve 3. During the static pressure change time of the hydrogen, periodically reciprocate the angle of the valve core 303. Deflect the valve core 303 in state three between 0° and 60° clockwise or counterclockwise. Periodically switch the main gas cylinder 101 and the auxiliary gas cylinder 102 for gas use, to ensure the activation of the hydrogen inside the hydrogen storage bottle group 1 and avoid quality changes caused by long-term storage of hydrogen.

[0077] Step 2-b: When the hydrogen lighting tower is working in an environment with low visibility, it needs a higher lighting power, more hydrogen energy, and a stable supply of hydrogen energy. Turn the valve core 303, turn the regulating valve 3 to state 2, open the outlet valve 402 to guide the hydrogen from the outlet duct 401 for gas supply and energy, and supply gas through the main gas cylinder 101 and the auxiliary gas cylinder 102 at the same time to increase the power generated by hydrogen energy and ensure the stability of hydrogen energy supply.

[0078] Step 2-c: While supplying gas and energy through the hydrogen storage bottle group 1, the air pressure detection submodule records the air pressure changes on the inner walls of the main gas bottle 101 and the auxiliary gas bottle 102 in real time, and transmits the data to the data comparison submodule. The data comparison submodule compares and detects the data changes, monitors the air pressure of the hydrogen storage bottle group 1 in real time, avoids leakage inside the device during use, and performs leak detection autonomously without stopping the gas supply to the hydrogen energy lighthouse;

[0079] Specifically, during the use of the hydrogen storage bottle group 1, the air pressure of one of the main gas bottle 101 or the auxiliary gas bottle 102 suddenly drops, and the valve control submodule is controlled to close the pressure reducing valve 201 on the top of the gas bottle on the side where the air pressure drops, and at the same time, the control valve 3 is adjusted to state two, and the two groups of gas guide pipes 2, the control valve 3 and the gas bottle with stable air pressure on one side are connected. The air pressure of the main gas bottle 101 and the auxiliary gas bottle 102 are recorded in real time through the pressure detection submodule again, and the location of the leakage problem is quickly determined. The valve in the damaged section is closed in time through the valve control submodule to further reduce the waste of hydrogen energy.

[0080] Step 2-c includes the following specific steps:

[0081] Step 2-c1: When the pressure of the gas cylinder on the side where the pressure drops is closed, after the pressure reducing valve 201 on the top is closed, the pressure detection submodule records the real-time pressure change, and the recorded data is transmitted to the data comparison submodule for data comparison. If the pressure of the gas cylinder on the side where the pressure drops remains stable, while the pressure data of the other gas cylinder steadily decreases, but the pressure drop rate accelerates, it means that there is damage and leakage in the air guide line 2 on the gas cylinder on the side where the pressure drops;

[0082] When there is a damage or leakage in the gas pipeline 2 on the gas cylinder on the side where the air pressure drops, gas can only be supplied through a single gas cylinder. The pressure reducing valve 201 and the electric control valve 203 are controlled by the valve control submodule, and the control valve 3 is turned to state three to disconnect the connection between the gas cylinder on the side of the damaged gas pipeline 2 and the gas outlet pipeline 4. Gas is supplied through a single gas cylinder to maintain the continuous operation of the hydrogen energy lighting lighthouse and reduce the impact of pipeline damage on the lighthouse operation.

[0083] Step 2-c2: If the gas pressure of the gas cylinder on the side where the gas pressure drops continues to drop, when the regulating valve 3 is in state 2, the gas cylinder on the side where the gas pressure is stable is used to supply gas to the hydrogen energy lighthouse. At the same time, the gas pressure data of the gas cylinder steadily decreases, and the rate of pressure drop remains unchanged, indicating that the gas cylinder on the side where the gas pressure drops is damaged or leaking;

[0084] When the gas cylinder on the side where the air pressure drops is damaged and leaking, the gas outlet valve 402 is closed through the valve control submodule, the main gas cylinder 101 and the auxiliary gas cylinder 102 are connected, and the residual gas in the damaged gas cylinder is introduced into the intact gas cylinder by the pressure reducing valve 201 in cooperation with the control valve 3. After the remaining gas is transferred, the electric control valve 203 on the side of the damaged gas cylinder is closed, and the remaining intact gas cylinder is used for gas and energy supply, and the gas is recovered in time. In the case of damage and leakage, the device reduces the leakage of hydrogen energy and ensures the stability of hydrogen supply;

[0085] Furthermore, when the regulating valve 3 is in state three, hydrogen flows into the valve body 301 through the gas guiding elbow 202, and then flows through the inner wall of the through hole 304 to the gas outlet duct 401 for discharge. The hydrogen passes through the trumpet-shaped inner wall in the through hole 304, and a Tesla valve structure is formed between the through hole 304 and the valve body 301. An airflow swirl is generated in the through hole 304 to avoid gas reflux and ensure the stability of airflow transmission.
