[0035] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0036] Embodiment 1:

[0037] A liquefied gas storage tank capable of heat insulation, as Figures 1-5 shown, includes a tank body 1. A protection cylinder 12 is installed at the top of the tank body 1, and a sealing cover 11 is provided on the protection cylinder 12. An alarm assembly 9 is provided on the sealing cover 11. A gas pipe 13 is connected to the middle position at the top of the tank body 1. A regulating valve 8 is installed on the gas pipe 13. A gas transmission pipe 10 extending outside the protection cylinder 12 is installed on one side of the gas pipe 13. When exhaust gas is required, the regulating valve 8 can be rotated so that the regulating valve 8 no longer blocks the gas pipe 13. At this time, liquefied gas will enter the interior of the gas transmission pipe 10. A thermal insulation layer 2 is provided on the inner wall of the tank body 1. The setting of the thermal insulation layer 2 can make the tank body 1 have a heat insulation effect, thereby improving the use effect of the tank body 1. Threads are provided on the inner wall of the sealing cover 11 and the outer wall of the protection cylinder 12. The sealing cover 11 is threadedly connected to the protection cylinder 12, which is convenient for the user to rotate the sealing cover 11 and screw the sealing cover 11 out of the protection cylinder 12, so as to facilitate the user to rotate the regulating valve 8.

[0038] Specifically, the alarm assembly 9 includes an alarm 903 installed on one side of the top of the sealing cover 11, a trigger switch 904 installed above the interior of the sealing cover 11, and two guide rods 906. A pressure contact plate 907 is sleeved between the two guide rods 906. A guide hole 905 is opened on the pressure contact plate 907. The trigger switch 904 is located directly above the pressure contact plate 907. The pressure contact plate 907 is slidably connected to the guide rods 906. When a gas leakage occurs, liquefied gas will enter the space formed by the sealing cover 11 and the protection cylinder 12. As the liquefied gas continues to leak, the air pressure between the sealing cover 11 and the protection cylinder 12 will increase. The trigger switch 904 is electrically connected to the alarm 903. When the trigger switch 904 is pressed, it will activate the alarm 903, causing the alarm 903 to alarm, so as to remind the surrounding personnel that the gas storage tank has a gas leakage situation.

[0039] Specifically, the alarm component 9 further includes a storage battery 901 installed inside the cover 11 and a charging port 902 opened on one side of the cover 11. The storage battery 901 is electrically connected to the trigger switch 904 and the alarm 903 respectively. The storage battery 901 can store electricity, and the setting of the charging port 902 facilitates charging the storage battery 901.

[0040] Embodiment 2:

[0041] On the basis of the above Embodiment 1, in order to prevent liquefied gas from flowing through the gap between the pressure contact plate 907 and the guide rod 906 to the upper part of the pressure contact plate 907, the following structure will be set up.

[0042] Refer to Figure 2 and Figure 5 . A sealing ring 908 is provided on the inner wall of the guide hole 905, and the inner wall of the sealing ring 908 is fitted with the guide rod 906. The outer wall of the pressure contact plate 907 is fitted with the inner wall of the cover 11. The setting of the sealing ring 908 can improve the sealing performance between the guide rod 906 and the pressure contact plate 907, and prevent liquefied gas from flowing upward through the gap between the guide rod 906 and the pressure contact plate 907.

[0043] Embodiment 3:

[0044] On the basis of the above Embodiment 1, in order to facilitate the transportation of the tank body 1, the following structure will be set up.

[0045] Refer to Figures 1-3 . A base 3 is installed at the bottom of the tank body 1, and universal wheels 4 are provided around the bottom of the base 3. The setting of the universal wheels 4 facilitates the movement of the gas storage tank and is convenient for transporting the gas storage tank.

[0046] Embodiment 4:

[0047] On the basis of the above Embodiment 3, in order to improve the stability of the tank body 1 and prevent the tank body 1 from moving randomly, the following structure will be set up.

[0048] Refer to Figures 1-3 . Threaded shafts 5 are threadedly connected to both sides of the top of the base 3, and a cushion plate 7 is installed at the bottom end of the threaded shaft 5. And the top end of the threaded shaft 5 is connected to a turntable 6, which is convenient for the user to rotate the threaded shaft 5 through the turntable 6, so that the threaded shaft 5 moves and drives the cushion plate 7 to move, thereby adjusting the height of the cushion plate 7.

[0049] The working principle of the utility model is as follows: first, the setting of the heat-insulating layer 2 can make the tank body 1 have a heat-insulating effect. When the tank body 1 needs to be transported, the user rotates the threaded shaft 5 through the turntable 6, so that the threaded shaft 5 moves up and drives the pad 7 to move up, so that the pad 7 is no longer in contact with the ground, and then the tank body 1 can be moved through the universal wheel 4. When the tank body 1 does not need to be moved, the user rotates the threaded shaft 5 in the opposite direction, so that the pad 7 moves down and fits with the ground, thereby preventing the tank body 1 from moving at will;

[0050] When exhaust is required, the sealing cover 11 can be rotated to unscrew the sealing cover 11 from the protective cylinder 12, and then the user can rotate the regulating valve 8 so that the liquefied gas can be discharged through the gas pipe 10. When exhaust is not required, the sealing cover 11 can be rotated back to the protective cylinder 12 to protect the regulating valve 8.

[0051] When a gas leak occurs, the liquefied gas will enter the space formed by the cover 11 and the protective tube 12. As the liquefied gas continues to leak, the air pressure between the cover 11 and the protective tube 12 will increase, pushing the touch plate 907 upward. When the touch plate 907 touches the trigger switch 904, the trigger switch 904 will activate the alarm 903, causing the alarm 903 to sound an alarm to remind surrounding personnel that the gas tank is leaking, allowing personnel to deal with the leaking gas tank in time.

[0052] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
