Description

Technical Field

[0001] The present invention belongs to the technical field of protective devices, and relates to a solid-state hydrogen storage safety protection device and method. Background Art

[0002] Solid-state hydrogen storage refers to the technology in which solid materials react with hydrogen in a physical or chemical form to combine, and store hydrogen in the form of atoms, molecules, or ions in solid-state hydrogen storage materials. Common solid-state hydrogen storage materials include metal hydrides, porous materials, and some new nanomaterials, etc. These materials have significant advantages in storing hydrogen. For example, metal hydrides can store hydrogen at relatively low pressures and have a high storage density. There are obvious deficiencies in the protection of existing hydrogen storage tanks. For the external protection of hydrogen storage tanks, only basic measures such as waterproofing and sun protection are often considered, while the protection against accidental situations such as collisions and fires is ignored.

[0003] During the transportation of hydrogen storage tanks, once a collision accident occurs, the tank wall may be damaged due to impact, resulting in hydrogen leakage. In addition, in the event of a fire, the protection ability of hydrogen storage tanks is insufficient, easily leading to dangerous situations such as explosions. And during the long-term use of hydrogen storage tanks, the seals age and are damaged, resulting in a relatively high risk of hydrogen leakage. Hydrogen leakage not only causes energy waste but also may trigger safety accidents such as explosions. Summary of the Invention

[0004] The present invention aims at the problems of the existing technology and provides a solid-state hydrogen storage safety protection device and method.

[0005] A solid-state hydrogen storage safety protection device, the inner cavity of the protection cabin is connected and installed with a hydrogen storage tank. One end of the inner cavity of the protection cabin is installed with a pressure sensor and an infrared sensor. The two sides of the inner cavity of the protection cabin are respectively connected with linear motors, and the moving ends of the linear motors are respectively connected with a temperature sensor and a hydrogen sensor. The top end of the protection cabin is connected with a spray rack, and the input end of the spray rack is connected with a water inlet pipe connected to the top end of the protection cabin. One side of the upper end of the protection cabin is connected with an alarm. One end of the protection cabin is respectively connected with a first pressure relief valve and a second pressure relief valve. The second pressure relief valve is connected with one end of the hydrogen storage tank. The two sides of the protection cabin are connected with heat dissipation fins. One end of the protection cabin away from the first pressure relief valve and the second pressure relief valve is connected with a movable seat. The inner part of the movable seat is rotatably connected with a cabin door. A servo motor is connected to the movable seat. One side of the cabin door is connected with a controller, and the inside of the controller is connected with a collection module and a control module.

[0006] Both sides of the bottom end of the hydrogen storage tank are respectively welded with fixing seats, and the fixing seats are connected with the bottom end of the inner cavity of the protection cabin. The linear motor can drive the temperature sensor and the hydrogen sensor to reciprocate inside the protection cabin. The four corners of the bottom end of the protection cabin are connected with shock absorbers, the bottom ends of the shock absorbers are connected with support seats, and the outside of the shock absorbers is sleeved with springs. The upper and lower ends of the springs are respectively connected with the bottom end of the protection cabin and the upper end of the support seat.

[0007] A solid-state hydrogen storage safety protection method includes the following steps:

[0008] The protection cabin serves as an external protection to protect the hydrogen storage tank. The fixing seat welded to the bottom end of the hydrogen storage tank is connected to the inner bottom end of the protection cabin to improve the firmness of the connection between the two. Inside the protection cabin, there are a temperature sensor, a hydrogen sensor, and an infrared sensor. The temperature sensor monitors the internal temperature of the protection cabin in real time to prevent the internal temperature from being too high and affecting the safety of the hydrogen storage tank. The hydrogen sensor monitors the hydrogen storage tank to prevent hydrogen leakage. The infrared sensor prevents a fire from occurring inside the protection cabin. When a flame is generated, the infrared sensor can detect the infrared radiation emitted by the flame in the first place. A spray rack is installed at the top end inside the protection cabin. When a fire breaks out, hydrogen leaks, or the temperature of the tank body is too high inside the protection cabin, after the spray rack is connected to the water inlet pipe, it sprays inside the protection cabin to extinguish the flame, cool down the tank body, and dilute the hydrogen, thus buying time for subsequent fire rescue. A pressure sensor monitors the pressure inside the protection cabin. When the pressure inside is too high, a first pressure relief valve is used to relieve the pressure inside the protection cabin. Moreover, by starting the servo motor, the cabin door is opened to cooperate with the spray rack to dilute the hydrogen. By installing a first pressure relief valve and a second pressure relief valve, when the pressure inside the hydrogen storage tank is too high, the second pressure relief valve relieves the pressure of the hydrogen storage tank. When the hydrogen storage tank leaks and hydrogen accumulates inside the protection cabin, the first pressure relief valve timely relieves the pressure of the protection cabin. Shock absorbers are installed at the four corners of the bottom end of the protection cabin, and a support seat is installed at the bottom end to support the protection cabin. A spring is sleeved outside the shock absorber, and the spring cooperates with the shock absorber to play a role in buffering and shock absorption. By installing heat dissipation fins on both sides of the protection cabin, it assists the tank body in heat dissipation to ensure that the overall temperature of the device remains stable during long-term operation. An alarm is installed at the upper end of the protection cabin. The acquisition module and the control module in the controller collect and process the data of each sensor, and the control module controls the operation of the servo motor and the alarm to emit an audible and visual alarm to prompt relevant personnel. By installing a linear motor, it drives the hydrogen sensor and the temperature sensor to reciprocate inside the protection cabin to increase their monitoring range and improve the monitoring effect inside the protection cabin.

[0009] The advantages of the present invention are as follows: The protective cabin serves as an external protection to protect the hydrogen storage tank. The fixing seat welded to the bottom end of the hydrogen storage tank is connected to the inner bottom end of the protective cabin, which can improve the firmness of the connection between the two. At the same time, the protective cabin is equipped with a temperature sensor, a hydrogen sensor, and an infrared sensor inside. The temperature sensor can monitor the internal temperature of the protective cabin in real time to prevent the internal temperature from being too high and affecting the safety of the hydrogen storage tank. The hydrogen sensor can monitor the hydrogen storage tank to prevent leakage. The infrared sensor can prevent a fire from occurring inside the protective cabin. When a flame appears, the infrared sensor can detect the infrared radiation emitted by the flame in the first time. A spray rack is installed at the inner top end of the protective cabin. When a fire, hydrogen leakage, or excessive tank body temperature occurs inside the protective cabin, after the spray rack is connected to the water inlet pipe, it can spray the inside of the protective cabin to extinguish the flame, cool the tank body, and dilute the hydrogen, thus gaining time for subsequent fire fighting and rescue. The pressure sensor can monitor the pressure inside the protective cabin. When the pressure inside is too high, the first pressure relief valve can be used to relieve the pressure inside the protective cabin. Moreover, by starting the servo motor, the cabin door can be opened to cooperate with the spray rack to dilute the hydrogen. By installing the first pressure relief valve and the second pressure relief valve, when the pressure inside the hydrogen storage tank is too high, the second pressure relief valve can relieve the pressure of the hydrogen storage tank. When the hydrogen storage tank leaks and hydrogen accumulates inside the protective cabin, the first pressure relief valve can timely relieve the pressure of the protective cabin. Shock absorbers are installed at the four corners of the bottom end of the protective cabin, and a support seat is installed at its bottom end, which can support the protective cabin. A spring is sleeved outside the shock absorber, and the spring cooperates with the shock absorber to play a role in buffering and shock absorption. By installing heat dissipation fins on both sides of the protective cabin, it can assist the tank body in heat dissipation to ensure that the overall temperature of the device remains stable during long-term operation. An alarm is installed at the upper end of the protective cabin. The acquisition module and the control module in the controller collect and process the data of each sensor, and through the control module, it can control the operation of the servo motor and make the alarm emit a sound and light alarm to give a prompt to relevant personnel. Moreover, by installing a linear motor to drive the hydrogen sensor and the temperature sensor to reciprocate inside the protective cabin, the monitoring range can be increased and the monitoring effect of the inside of the protective cabin can be improved.
