[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention sets a zoom mechanism. When the amount of natural gas to be transported is large, the hydraulic device will control the telescopic rod to be in a retracted state, and the inner tube will be outside the storage tank, so that the volume of the entire storage tank becomes larger. When the amount of natural gas to be transported is small, the hydraulic device will make the telescopic rod in an extended state, so that the volume of the tank body becomes smaller, thereby reducing unnecessary heat transfer area and reducing evaporation rate. This flexible and variable structure is not available in existing fixed structure tanks.

[0026] 2. The present invention provides a closing mechanism. When the whole device overturns, the blocking rod will slide off the supporting plate, and the blocking rod will not hinder the closing plate. The elastic force of the telescopic spring will push the closing plate to move to the rear end of the air pipe. There is no vent at this position, so that the liquid in the storage tank will not leak.

[0027] 3. The present invention provides a stabilizing mechanism. The hydraulic rod is extended to make the fitting plate and the inner wall of the inner tank collide with each other, thereby increasing the fitting force between the inner tube and the storage tank. At the same time, the telescopic rod 2 is also extended to drive the support plate 2 to move toward the support plate 3 until the insertion column enters the slot, thereby realizing the longitudinal and transverse reinforcement of the inner tank, and preventing the inner tank from detaching from the storage tank when the vehicle rolls over, thereby causing liquid leakage.

[0028] 4. The present invention sets a top plate unit. When the device is transported in an area with hot weather, if the temperature sensor detects that the temperature of the surface of the storage tank is high, the nozzle will spray cooling water from the aquifer to the storage tank, so that the temperature of the storage tank is reduced. At the same time, the flushing of clean water can also wash away the dust on the storage tank to prevent the dust from hindering heat transfer and slowing down the temperature reduction of the storage tank. After the cooling water flows into the sump, it will be pumped back to the aquifer by a pump to achieve recycling.

[0029] 5. The present invention sets a tilt protection mechanism, and the quick-inflating air bag will slide down through the side frame. During this process, the quick-inflating air bag will expand rapidly, and then the magnetic block one on the other side will attract the magnetic block two, and the magnetic block one at the bottom will attract the magnetic plate, so that when the device is overturned, the storage tube will not directly contact the ground. To a certain extent, it also plays a role of landing cushioning, avoiding the storage tank from generating a large impact force with the ground and causing it to break.

[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0046] Example 1, using Figure 1-Figure 14 A liquefied natural gas transportation device with enhanced safety protection during transportation according to one embodiment of the present invention is described as follows.

[0047] like Figure 1-Figure 2 As shown, a liquefied natural gas transport device with enhanced safety protection during transportation of the present invention includes a transport vehicle body 1 providing a cockpit, a water collecting tank 2 is provided on the transport vehicle body 1 for collecting cooling water, and a dirt separating plate 3 is provided on the inner wall of the water collecting tank 2, and further includes:

[0048] A storage unit 4, for storing natural gas;

[0049] A top plate unit 5, used to protect the storage unit 4 from temperature and rollover problems;

[0050] A scaling unit 6 is used to increase and reduce the volume of the storage unit and reduce unnecessary heat transfer area;

[0051] An air suspension device 10 is provided at the bottom of the transport vehicle body 1 to improve the stability of the entire device on bumpy roads. Moving wheels 11 are provided on both sides of the air suspension device 10. A wire 7 is provided on the outer surface of the air suspension device 10. An information processor 8 is provided on the top of the wire 7. A road condition sensor 9 is provided on the information processor 8.

[0052] When the present invention is working, natural gas can be stored in the storage unit 4 first, and the scaling unit 6 can be controlled to work according to the amount of stored natural gas. Then the driver will control the transport vehicle 1 to drive. If rollover occurs during driving, the top plate unit 5 will protect the device, and the storage unit 4 also autonomously protects the stability of the internal structure.

[0053] like Figure 3 As shown, the scaling unit 6 includes a supporting plate 61, and a hydraulic device 62 is symmetrically arranged on the outer surface of the supporting plate 61. The output of the hydraulic device 62 acts on a telescopic rod 63. The output end of the telescopic rod 63 is fixedly connected to a supporting rod 64. The end of the supporting rod 64 away from the telescopic rod 63 is fixedly connected to an inner tube, and the radius of the inner tube is adapted to the storage unit 4.

[0054] When liquefied natural gas needs to be transported, the volume of the loading tank can be controlled according to the volume of the transported natural gas. When the amount of natural gas transported is large, the hydraulic device 62 will control the telescopic rod to be in a retracted state, and the inner tube will be outside the storage tank 42, so that the volume of the entire storage tank 42 becomes larger. When the amount of natural gas to be transported is small, the hydraulic device 62 will make the telescopic rod 63 in an extended state, so that the volume of the tank body becomes smaller, thereby reducing unnecessary heat transfer area and reducing the evaporation rate. This flexible and variable structure is not available in existing fixed structure tanks.

[0055] like Figure 3-Figure 4 As shown, the storage unit 4 includes a support frame 41, a storage tank 42 made of carbon nanotube reinforced composite material is fixedly connected to the top of the support frame 41, a control valve 43 is arranged at one end of the storage tank 42 away from the support vertical plate 61, and is used to control the natural gas to enter and flow out of the storage tank 42, a temperature sensor 46 is arranged on the outer surface of the storage tank, and an access end 44 is arranged on the outer surface of the control valve 43, and the access end 44 can be connected to a natural gas pipe 451, and a magnetic plate 47 with opposite magnetic properties is symmetrically arranged on the outer surface of the storage tank 42, and the storage unit 4 also includes:

[0056] A sealing mechanism 45 is used to prevent leakage of natural gas due to rupture of the control valve 43 when the device rolls over;

[0057] The stabilizing mechanism 48 is used to ensure the internal stability of the zoom unit 6 when the device rolls over.

[0058] like Figure 5-Figure 6 As shown, the closing mechanism 45 includes an air pipe 451 with an air vent 452 on its outer surface, a fixing block 453 is provided at one end of the air pipe 451, a supporting rod 454 is provided at the top of the fixing block 453, a supporting plate 455 is provided at one end of the supporting rod 454 away from the fixing block 453, a telescopic spring 458 is provided on the inner wall of the fixing block 453, and a closing plate 459 is fixedly connected to one end of the telescopic spring 458 away from the fixing block 453;

[0059] The closing mechanism 45 further includes a blocking rod 457 for blocking the movement of the closing plate 459 . A round block 456 is provided on the top of the blocking rod 457 , and the bottom of the round block 456 contacts the top of the supporting plate 455 .

[0060] If the entire device overturns due to road problems or accidents during transportation, causing the control valve 43 and the access end 44 to break, thereby causing natural gas leakage, when the entire device overturns, the blocking rod 457 will slide off the support plate 455, and the blocking rod 457 will not hinder the closing plate 459. The elastic force of the telescopic spring 458 will push the closing plate 459 to move to the rear end of the air pipe 451. There is no vent 452 at this position, so that the liquid in the storage tank 42 will not leak.

[0061] like Figure 7-Figure 8 As shown, the stabilizing mechanism 48 includes a connecting column 481, one end of the connecting column 481 is provided with a second fixing block 482, the outer surface of the second fixing block 482 is evenly provided with hydraulic rods 483, the output end of the hydraulic rod 483 is fixedly connected with a fitting plate 484, the hydraulic rod 483 is controlled by an operator driving the transport vehicle body 1, one end of the second fixing block 482 away from the connecting column 481 is fixedly connected with a second telescopic rod 485, the outer surface of the second telescopic rod 485 is fixedly connected with a second support plate 486, and the outer surface of the second support plate 486 is evenly provided with insertion columns 487;

[0062] The stabilizing mechanism 48 also includes a support plate three 488, and the outer surface of the support plate three 488 is provided with a slot 489 adapted to the insertion column 487, allowing the insertion column 487 to enter the slot 489, thereby improving the overall strength and stability.

[0063] When the device rolls over, the driver will activate the hydraulic rod 483, which will extend to make the fitting plate 484 abut against the inner wall of the inner tank 65, thereby increasing the fitting force between the inner tube and the storage tank 42. At the same time, the telescopic rod 485 will also extend to drive the support plate 2 486 to move toward the support plate 3 488 until the insertion column 487 enters the slot 489, thereby achieving longitudinal and lateral reinforcement of the inner tank 65 and preventing the inner tank 65 from detaching from the storage tank 42 when the vehicle rolls over, thereby causing liquid leakage.

[0064] The bottom of the support frame 41 is fixedly connected to the top of the transport vehicle body 1 , and one end of the air pipe 451 away from the fixed block 453 is fixedly connected to the inner wall of the storage tank 42 .

[0065] One end of the connecting column 481 is fixedly connected to the outer surface of the fixing block 1 453, and the supporting plate 3 488 is arranged on the inner wall of the inner tube.

[0066] The specific workflow is as follows:

[0067] When working, the volume of the loading tank can be controlled according to the volume of the transported natural gas. When the amount of natural gas transported is large, the hydraulic device 62 will control the telescopic rod to be in a retracted state, and the inner tube will be outside the storage tank 42, so that the volume of the entire storage tank 42 becomes larger. When the amount of natural gas to be transported is small, the hydraulic device 62 will make the telescopic rod 63 in an extended state, so that the volume of the tank body becomes smaller. When the device rolls over, the blocking rod 457 will slide off the support plate 455, and the blocking rod 457 will not hinder the closing plate 459, and the elasticity of the telescopic spring 458 will be reduced. The force will push the closing plate 459 to move to the rear end of the air pipe 451. There is no vent 452 at this position, so that the liquid in the storage tank 42 will not leak. At the same time, the driver will start the hydraulic rod 483, and the hydraulic rod 483 will extend to make the fitting plate 484 collide with the inner wall of the inner tank 65, thereby increasing the fitting force between the inner tube and the storage tank 42. At the same time, the telescopic rod 2 485 will also extend, driving the support plate 2 486 to move toward the support plate 3 488 until the insertion column 487 enters the slot 489, thereby realizing the longitudinal and lateral reinforcement of the inner tank 65.

[0068] Embodiment 2, use Figure 1-Figure 14 A liquefied natural gas transportation device with enhanced safety protection during transportation according to one embodiment of the present invention is described as follows.

[0069] like Figure 9-11 As shown, a liquefied natural gas transportation device with enhanced safety protection during transportation of the present invention is based on the first embodiment. The top plate unit 5 includes a fixed plate 51. An aquifer 52 is arranged on the top of the fixed plate 51. Nozzles 53 are symmetrically arranged on the bottom of the aquifer 52. The nozzles 53 face the storage tank 42. A water pipe 54 is arranged at the bottom of the aquifer 52. A pump 55 with a water inlet pipe 56 on the surface is provided at the bottom of the water pipe 54. The pump 55 is placed in the water collection tank 2. A tilting protection mechanism 57 is arranged on the top of the aquifer 52 to protect the storage tank 42 when the device rolls over.

[0070] When the device is transported in an area with relatively hot weather, if the temperature sensor 46 detects that the temperature on the surface of the storage tank 42 is relatively high, the nozzle 53 will spray the cooling water of the aquifer 52 toward the storage tank 42, so that the temperature of the storage tank 42 is reduced. At the same time, the flushing of clean water can also wash away the dust on the storage tank 42 to prevent the dust from hindering heat transfer, thereby slowing down the temperature reduction of the storage tank 42. After the cooling water flows into the sump 2, it will be pumped back to the aquifer 52 by the pump 55 for recycling.

[0071] The top plate unit 5 also includes side frames 58, which are symmetrically arranged on both sides of the aquifer 52. The top of the side frame 58 is fixedly connected with an arc plate 59. The arc plate 59 is evenly provided with magnetic blocks 510 on one side facing the tilt protection mechanism 57, and the magnetic properties of the magnetic blocks 510 on both sides are opposite.

[0072] like Figure 12-14 As shown, the tilt protection mechanism 57 includes a top box 571, a sliding rod 572 is provided at one end of the top box 571, a gravity block 573 is slidably connected to the outer surface of the sliding rod 572, impact columns 574 are symmetrically provided on both sides of the gravity block 573, side sealing mechanisms 575 are symmetrically provided on both sides of the top box 571, a quick-inflating bag 577 is placed on the inner wall of the top box 571, magnetic block 2 578 is provided on both sides of the quick-inflating bag 577, the magnetic properties of magnetic block 2 578 are the same as those of magnetic block 1 510 on the same side, and the magnetic properties of magnetic block 2 578 are opposite to those of magnetic plate 47 on the same side, and side grooves 576 are evenly provided on both sides of the top box 571.

[0073] When the device rolls over, the gravity block 573 will move along the sliding rod 572 toward the side of the rollover, so that the impact column 574 will collide with the sealing and testing mechanism, causing the quick-inflating air bag 577 to slide out of the top box 571, and the magnetic block 1 510 will repel the magnetic block 2 578 that is in contact with it at the beginning. With the resistance of the arc plate 59, the quick-inflating air bag 577 will slide down through the side frame 58. In this process, the quick-inflating air bag 577 will expand rapidly, and then the magnetic block 1 510 on the other side will be attracted to the magnetic block 2 578, and the magnetic block 1 510 at the bottom will be attracted to the magnetic plate 47, so that when the device rolls over, the storage tube will not directly contact the ground, and to a certain extent, it also plays a role of landing buffer, avoiding the storage tank 42 from generating a large impact force with the ground and breaking.

[0074] like Fig.13 As shown, the side sealing mechanism 575 includes a fixed block three 5751, the outer surface of the fixed block three 5751 is rotatably connected to a rotating shaft 5752, one end of the rotating shaft 5752 is fixedly connected to a cover plate 5753, the cover plate 5753 is provided with a plug plate 5754 adapted to the side groove 576, and the end of the cover plate 5753 away from the rotating shaft 5752 is provided with a stop plate 5755, which will be hit by the impact column 574.

[0075] After the impact column 574 collides with the support plate 5755, the rotating shaft 5752 and the cover plate 5753 will rotate upward, so that the quick-inflating air bag 577 can be moved out of the top box 571. When not tilted, the plug plate 5754 will adapt to the inner groove to ensure that the quick-inflating air bag 577 is inside the top box 571.

[0076] The bottom of the fixed plate 51 is fixedly connected to the top of the transport vehicle body 1 , the bottom of the top box 571 is fixedly connected to the top of the aquifer 52 , and the outer surface of the fixed block three 5751 is fixedly connected to the outer surface of the top box 571 .

[0077] The specific workflow is as follows:

[0078] During operation, when the device is transported in a hot area, if the temperature sensor 46 detects that the surface temperature of the storage tank 42 is high, the nozzle 53 will spray the cooling water of the aquifer 52 to the storage tank 42, so that the temperature of the storage tank 42 is reduced. At the same time, the flushing of clean water can also flush away the dust on the storage tank 42 to prevent the dust from hindering heat transfer, so that the temperature of the storage tank 42 decreases slowly. After the cooling water flows into the water collection tank 2, it will be pumped back to the aquifer 52 by the pump 55 to achieve recycling. When the device tips over, the gravity block 573 will move along the sliding rod 572 toward the tipping side, causing the impact column 574 to collide with the sealing and testing mechanism, causing the quick-inflating air bag 577 to slide out of the top box 571. During this process, the quick-inflating air bag 577 will expand rapidly, and then the magnetic block 1 510 on the other side will be attracted to the magnetic block 2 578, and the magnetic block 1 510 at the bottom will be attracted to the magnetic plate 47, so that when the device tips over, the storage tube will not directly contact the ground.

[0079] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
