[0024] The embodiment of the present application provides an integrated natural gas storage and transportation safety protection device, which effectively solves the current traditional transportation method of filling natural gas into a storage tank for transportation. However, if the liquid natural gas shakes left and right for a long time during transportation, it may cause stress concentration in certain parts of the tank, such as welding points, and the connection between the head and the cylinder, increasing the risk of fatigue cracks and damage in these parts, thereby causing the risk of natural gas leakage. The cooperation between the damping rod and the spring will greatly reduce the amplitude of the shaking. When the demagnetizing alloy tank has a tendency to move to the left or right, the demagnetizing alloy tank drives the weight to move in a clockwise or counterclockwise circle, and the weight drives the second arc magnet to move in a clockwise or counterclockwise circle. When the second arc magnet moves toward the first arc magnet, the two repel each other and cannot approach each other, causing the natural gas to leak. The center of gravity inside the demagnetizing alloy tank will not change. The bearings provide support and reduce the friction of the device, thereby achieving the function of adjusting the center of gravity of natural gas inside the demagnetizing alloy tank. During transportation, the air pressure on both sides of the protective shell is low, and the air is poured into the protective shell through the vents. The fan blades rotate as the air is poured in, accelerating the entry and outflow of air. At the same time, the explosion-proof electric ball valve is opened, and the explosion-proof electric ball valve allows the nitrogen inside the nitrogen tank to flow out slowly and cover the surface of the demagnetizing alloy tank. Even if there is a natural gas leak, the nitrogen can isolate oxygen and reduce the risk of explosion to a certain extent. The vents are equipped with catalytic combustion sensors. When the gas is discharged from the inside of the protective shell through the vents, it will be detected and the staff will be alarmed, thereby achieving the function of detecting natural gas leaks.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the current technical problem that in the traditional transportation method, natural gas is filled inside a storage tank for transportation. However, if the liquid natural gas sloshes left and right for a long time during transportation, it may cause stress concentration at some parts of the tank body, such as the welding points, the connection between the head and the cylinder body, etc., increasing the risk of fatigue cracks and damage in these parts, thus causing the risk of natural gas leakage. The general idea is as follows: An integrated natural gas storage and transportation safety protection device includes a protective shell 11. Inside the protective shell 11, there is a center-of-gravity adjustment mechanism. The center-of-gravity adjustment mechanism includes a support plate 12, a ring 13, a first arc magnet 14, a second arc magnet 15, a heavy object 16, a bearing 17, and a degaussing alloy tank 18. The ring 13 is fixedly installed on the top of the support plate 12. The first arc magnet 14 is fixedly installed inside the ring 13. The second arc magnet 15 is slidably installed inside the ring 13. The heavy object 16 is fixedly installed on the side wall of the second arc magnet 15. The heavy object 16 is slidably installed inside the ring 13. The heavy object 16 is fixedly installed on the side wall of the degaussing alloy tank 18. The bearing 17 is fixedly installed on the side wall of the degaussing alloy tank 18. A damping rod 19 is fixedly installed at the bottom of the protective shell 11. A spring 21 is sleeved on the side wall of the damping rod 19. The cooperation of the damping rod 19 and the spring 21 will greatly reduce the amplitude of sloshing. When the degaussing alloy tank 18 has a tendency to move left or right, the degaussing alloy tank 18 drives the heavy object 16 to move in a clockwise or counterclockwise circular motion. The heavy object 16 drives the second arc magnet 15 to move in a clockwise or counterclockwise circular motion. When the second arc magnet 15 moves towards the first arc magnet 14, the two repel each other and cannot approach, so that the center of gravity of the natural gas inside the degaussing alloy tank 18 will not change. The bearing 17 provides a supporting force and reduces the friction of the device operation, thereby achieving the function of adjusting the center of gravity of the natural gas inside the degaussing alloy tank 18.

[0027] A bearing plate 22 is fixedly installed at the bottom of the damping rod 19. Ventilation openings are provided on the side wall of the protective shell 11. A filter screen 23 is fixedly installed inside the ventilation openings, and a catalytic combustion type sensor is fixedly installed inside the ventilation openings. A fan blade 24 is rotatably installed on the side wall of the support plate 12. A nitrogen gas tank 25 is fixedly installed at the top of the protective shell 11. An explosion-proof electric ball valve is installed at the bottom of the nitrogen gas tank 25 (the explosion-proof electric ball valve mainly consists of two parts: a ball valve body and an explosion-proof electric actuator. There is a through hole on the sphere of the ball valve. When the sphere rotates to make the through hole coincide with the pipeline axis, the valve is in the open state and gas can flow smoothly. When the sphere rotates to make the through hole perpendicular to the pipeline axis, the valve is in the closed state to prevent gas flow. The electric actuator is connected to the power supply and the control signal source through a cable. The power supply provides the electric energy required for the actuator to work. Control signals (such as opening, closing, adjusting, etc. instructions) are transmitted to the actuator through the cable. The electric actuator then drives through the internal motor and converts the electric energy into mechanical energy to control the opening and closing actions of the ball valve. The explosion-proof electric actuator receives control signals (such as electric signals from a remote control system), converts the electric energy into mechanical energy, and the motor inside the actuator drives the valve stem of the ball valve to rotate through a reduction device, thereby driving the sphere to rotate and realizing the opening and closing actions of the valve. During the entire working process, due to the explosion-proof design, it can ensure safe and reliable operation in an inflammable and explosive environment and will not cause explosion accidents due to factors such as electric sparks). The explosion-proof electric ball valve is fixedly installed at the bottom of a connection tank 26, and the connection tank 26 is fixedly installed inside the protective shell 11. When in the transportation process, the air pressure on both sides of the protective shell 11 is relatively low, and air is poured into the inside of the protective shell 11 through the ventilation openings. The fan blade 24 rotates as the air is poured in, accelerating the entry and outflow of air. At the same time, the explosion-proof electric ball valve is opened, and the nitrogen gas inside the nitrogen gas tank 25 slowly flows out and covers the surface of the degaussing alloy tank 18. Even if there is a natural gas leak, the nitrogen gas can isolate oxygen and reduce the risk of explosion to a certain extent. Moreover, catalytic combustion type sensors are provided at all the ventilation openings. When the gas discharged from the inside of the protective shell 11 passes through the ventilation openings, it will be detected and an alarm will be given to the staff, thus achieving the function of detecting natural gas leaks).

[0028] An air outlet pipe 27 is fixedly installed on the side wall of the degaussing alloy tank 18, and a valve 28 is fixedly installed on the side wall of the air outlet pipe 27, which is convenient for taking out the natural gas inside.

[0029] In view of the problems existing in the prior art, the utility model provides an integrated natural gas storage and transportation safety protection device. The cooperation of the damping rod 19 and the spring 21 will greatly reduce the amplitude of shaking. When the degaussing alloy tank 18 has a tendency to move left or right, the degaussing alloy tank 18 drives the heavy object 16 to move in a clockwise or counterclockwise circular motion. The heavy object 16 drives the second arc-shaped magnet 15 to move in a clockwise or counterclockwise circular motion. When the second arc-shaped magnet 15 moves towards the first arc-shaped magnet 14, the two repel each other and cannot approach, so that the center of gravity of the natural gas inside the degaussing alloy tank 18 will not change. The bearing 17 provides a supporting force and reduces the friction of the device operation, so as to achieve the function of adjusting the center of gravity of the natural gas inside the degaussing alloy tank 18. When in the transportation process, the air pressure on both sides of the protective shell 11 is relatively low. Air is filled into the protective shell 11 through the ventilation openings. The fan blades 24 rotate as the air is filled, accelerating the entry and exit of air. At the same time, the explosion-proof electric ball valve is opened. The explosion-proof electric ball valve makes the nitrogen in the nitrogen tank 25 flow out slowly and cover the surface of the degaussing alloy tank 18. Even if there is a natural gas leak, nitrogen can isolate oxygen and reduce the risk of explosion to a certain extent. And catalytic combustion sensors are provided at all the ventilation openings. When the gas is discharged from the inside of the protective shell 11 and passes through the ventilation openings, it will be detected and an alarm will be given to the staff, so as to achieve the function of detecting natural gas leaks.

[0030] Working principle:

[0031] First step, when in the transportation process, the air pressure on both sides of the protective shell 11 is relatively low. Air is filled into the protective shell 11 through the ventilation openings. The fan blades 24 rotate as the air is filled, accelerating the entry and exit of air. At the same time, the explosion-proof electric ball valve is opened. The explosion-proof electric ball valve makes the nitrogen in the nitrogen tank 25 flow out slowly and cover the surface of the degaussing alloy tank 18. Even if there is a natural gas leak, nitrogen can isolate oxygen and reduce the risk of explosion to a certain extent. And catalytic combustion sensors are provided at all the ventilation openings. When the gas is discharged from the inside of the protective shell 11 and passes through the ventilation openings, it will be detected and an alarm will be given to the staff, so as to achieve the function of detecting natural gas leaks.

[0032] Second step, when encountering a bumpy section during the transportation process, the cooperation of the damping rod 19 and the spring 21 will greatly reduce the amplitude of shaking. When the degaussing alloy tank 18 has a tendency to move left or right, the degaussing alloy tank 18 drives the heavy object 16 to move in a clockwise or counterclockwise circular motion. The heavy object 16 drives the second arc-shaped magnet 15 to move in a clockwise or counterclockwise circular motion. When the second arc-shaped magnet 15 moves towards the first arc-shaped magnet 14, the two repel each other and cannot approach, so that the center of gravity of the natural gas inside the degaussing alloy tank 18 will not change. The bearing 17 provides a supporting force and reduces the friction of the device operation, so as to achieve the function of adjusting the center of gravity of the natural gas inside the degaussing alloy tank 18.

[0033] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
