However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides an explosion-proof gas storage tank. The explosion-proof gas storage tank includes a gas storage tank 100, a cylindrical shell 101, a lower shell 102 and an upper shell 103. The lower shell 102 is fixed to the bottom of the cylindrical shell 101, and the upper shell 103 is fixed to the top of the cylindrical shell 101. The lower shell 102 is provided with a drain port 102-1.

[0031] The cylindrical shell 101, the lower shell 102 and the upper shell 103 together constitute the tank body of the gas storage tank 100. During the use of the gas storage tank 100, condensate will be generated inside the tank, and the accumulated water can be discharged through the drain port 102-1.

[0032] The drainage assembly 200 is located at the bottom of the lower housing 102 and includes a drainage component 201. The drainage component 201 includes a drainage pipe 201a, a fixing plate 201b, a rotating column 201c, and a rotating plate 201d. The drainage pipe 201a is fixed to the bottom of the lower housing 102. The fixing plate 201b is inserted into the drainage pipe 201a and fixed to the inner wall of the drainage pipe 201a. The bottom of the rotating column 201c is connected to the fixing plate 201b by a bearing. The rotating plate 201d is fixed on the rotating column 201c.

[0033] The drain component 201 is used to drain the water accumulated in the gas storage tank 100. The rotating plate 201d can rotate relative to the fixed plate 201b. Through the cooperation between the rotating plate 201d and the fixed plate 201b, the flow and closing of the drain pipe 201a are controlled.

[0034] The drainage assembly 200 also includes a trigger 202 located inside the cylindrical housing 101. This trigger 202 includes a fixed rod 202a, a floating ball 202b, a fixed frame 202c, a moving rod 202d, a lifting column 202e, a lower ring 202f, a first spiral block 202g, an upper ring 202h, a second spiral block 202i, a moving ring 202j, a lower push block 202k, and an upper push block 202l. The fixed rod 202a is fixed to the inner wall of the lower housing 102, the floating ball 202b is fitted inside the fixed rod 202a, and the fixed frame 202c is fixed to the inner wall of the cylindrical housing 101. 02c has a movable groove 202c-1, the movable rod 202d slides in the movable groove 202c-1, the lifting column 202e is fixed below the movable rod 202d, the lower ring 202f is fixed on the rotating column 201c, the first spiral block 202g is fixed on the lower ring 202f, the upper ring 202h is fixed on the rotating column 201c, the second spiral block 202i is fixed on the upper ring 202h, the movable ring 202j is sleeved on the rotating column 201c, the lower push block 202k is fixed on the rotating column 201c, and the upper push block 202l is fixed on the rotating column 201c.

[0035] The trigger 202 is set to rotate the rotating column 201c at regular intervals, thereby controlling the flow of the drain pipe 201a and completing the drainage at regular intervals.

[0036] The floating ball 202b has a hole corresponding to the fixed rod 202a. When there is water in the air tank 100, the floating ball 202b floats on the water surface by buoyancy. As the water increases, the floating ball 202b will also move upward along the fixed rod 202a.

[0037] The fixed frame 202c provides stable support for the movable rod 202d and restricts its movement. The movable rod 202d also has holes corresponding to the fixed rod 202a. The fixed rod 202a is longer, and the movable rod 202d can only move within the movable slot 202c-1, ensuring that the floating ball 202b remains below the movable rod 202d and does not separate from the fixed rod 202a. When the floating ball 202b moves upward, it exerts an upward thrust on the movable rod 202d, causing the movable rod 202d to move... The moving rod 202d moves upward along the moving groove 202c-1, thereby driving the lifting column 202e to move upward. The movement of the lifting column 202e will drive the moving ring 202j to move, thereby driving the upper push block 202l to move upward and contact the second spiral block 202i. The upper push block 202l will continue to move along the end face of the second spiral block 202i, thereby causing the rotating column 201c to rotate, thereby causing the rotating plate 201d to rotate relative to the fixed plate 201b, thereby allowing the drain pipe 201a to flow and realize drainage.

[0038] As the water in the gas storage tank 100 is drained, the floating ball 202b will move downwards, and the moving rod 202d will also move downwards, thereby driving the lifting column 202e to move downwards. The pushing block 202k moves downwards in sync and comes into contact with the first spiral block 202g, which causes the rotating column 201c to rotate in the opposite direction, thereby causing the rotating plate 201d to rotate in the opposite direction relative to the fixed plate 201b, and thus causing the drain pipe 201a to close again.

[0039] Example 2

[0040] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the drainage component 200 also includes an auxiliary component 203, which is set at the bottom of the lifting column 202e. It includes a fixing block 203a, a connecting rod 203b, and a connecting block 203c. The fixing block 203a is fixed to the bottom of the lifting column 202e, the connecting rod 203b is fixed to the fixing block 203a, and the two ends of the connecting block 203c are fixed to the connecting rod 203b and the moving ring 202j, respectively.

[0042] The auxiliary component 203 is used to connect the lifting column 202e and the moving ring 202j, so that the movement of the lifting column 202e can drive the moving ring 202j to move synchronously, thereby controlling the rotation of the rotating column 201c.

[0043] Specifically, the lower push block 202k can contact the first spiral block 202g, and the upper push block 202l can contact the second spiral block 202i.

[0044] Both ends of the first spiral block 202g and the second spiral block 202i have horizontal blocks to ensure that the upper push block 202l and the lower push block 202k do not separate from the first spiral block 202g and the second spiral block 202i when they move. When the lower push block 202k moves along the end face of the first spiral block 202g, it will cause the rotating column 201c to rotate 180 degrees. When the upper push block 202l moves along the end face of the second spiral block 202i, it will also cause the rotating column 201c to rotate 180 degrees.

[0045] Initially, the moving ring 202j is at its lowest position. At this time, the push block 202k is in contact with the first spiral block 202g, and the drain pipe 201a is closed under the cooperation of the fixed plate 201b and the rotating plate 201d, so the water does not flow. As the floating ball 202b moves upward, it drives the moving ring 202j to move upward. The push block 202k will move upward with the moving ring 202j, and the push block 202k will separate from the first spiral block 202g. When the push block 202l contacts the second spiral block 202i, the push block 202l moves along the end face of the second spiral block 202i, thereby causing the rotating column 201c to rotate. The rotating plate 201d and the fixed plate 201b rotate relative to each other. The rotating plate 201d rotates by an angle, allowing the drain pipe 201a to flow, thus realizing drainage. At this time, the lower ring 202f and the first spiral block 202g will also rotate by the same angle.

[0046] As the water level in the gas storage tank 100 decreases, the floating ball 202b moves downward. The floating ball 202b will not exert a pushing force on the moving rod 202d, which will then move downward, causing the moving ring 202j to move downward. At this time, the upper push block 202l will separate from the second spiral block 202i. When the lower push block 202k contacts the first spiral block 202g again, the moving ring 202j will continue to move downward, causing the lower push block 202k to move along the first spiral block 202g and causing the rotating plate 201d to rotate in the opposite direction by the same angle, thus closing the drain pipe 201a again.

[0047] Specifically, a first through groove 201b-1 is provided on the fixing plate 201b.

[0048] Specifically, a second through groove 201d-1 is provided on the rotating plate 201d.

[0049] In the initial state, the first channel 201b-1 and the second channel 201d-1 are in symmetrical positions, and the water cannot flow out of the tank through the fixed plate 201b and the rotating plate 201d. As the rotating column 201c rotates, the rotating plate 201d rotates a certain angle relative to the fixed plate 201b, and the first channel 201b-1 and the second channel 201d-1 will have an overlapping part. At this time, the accumulated water will flow out of the tank from the overlapping part, thus achieving drainage.

[0050] A sealing ring is provided at the bottom of the rotating plate 201d to ensure the sealing between the rotating plate 201d and the fixed plate 201b when the first through groove 201b-1 and the second through groove 201d-1 are in symmetrical positions.

[0051] Specifically, a spring 203d is fixed to one side of the moving rod 202d, and the other end of the spring 203d is fixed to the inner wall of the moving groove 202c-1.

[0052] Spring 203d is used to apply a continuous pushing force to moving rod 202d to ensure that, in the absence of other external forces, moving rod 202d is located at the lowest position of moving groove 202c-1. At this time, push block 202k is in contact with first spiral block 202g, first through groove 201b-1 and second through groove 201d-1 are in symmetrical positions, and water cannot flow to the outside of the tank through fixed plate 201b and rotating plate 201d.

[0053] Example 3

[0054] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, the end faces of the lower push block 202k and the upper push block 202l are arc-shaped.

[0056] The arc-shaped design ensures that the lower push block 202k and the upper push block 202l can slide smoothly along the end faces of the first spiral block 202g and the second spiral block 202i.

[0057] Specifically, the gas storage tank 100 is made of low-alloy high-strength steel.

[0058] Low-alloy high-strength steel has high strength and good toughness, and can withstand greater pressure, thereby improving the explosion-proof effect of the gas storage tank 100. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle.

[0059] Specifically, the gas storage tank 100 also includes support legs 104.

[0060] There are three support legs 104, which provide stable support for the gas storage tank 100.

[0061] Specifically, the cylindrical housing 101 is provided with an air inlet 105 and an air outlet 106.

[0062] The main function of the air inlet 105 is to introduce external compressed gas into the air storage tank, and the air outlet 106 delivers the compressed gas stored in the air storage tank to downstream gas-using equipment or systems.

[0063] In use, in the initial state, the moving ring 202j is at the lowest position. At this time, the push block 202k is in contact with the first spiral block 202g, the first through groove 201b-1 and the second through groove 201d-1 are in symmetrical positions, and the water cannot flow to the outside of the tank through the fixed plate 201b and the rotating plate 201d, and the drain pipe 201a is closed.

[0064] When there is water in the gas storage tank 100, the floating ball 202b floats on the water surface due to buoyancy. As the water increases, the floating ball 202b will also move upward along the fixed rod 202a, causing the moving rod 202d to move upward along the moving groove 202c-1, which in turn drives the lifting column 202e to move upward. The movement of the lifting column 202e will drive the moving ring 202j to move, which in turn drives the upper push block 202l to move upward and contact the second spiral block 202i. The upper push block 202l will continue to move along the end face of the second spiral block 202i, thereby causing the rotating column 201c to rotate. After the rotating plate 201d rotates relative to the fixed plate 201b by a certain angle, there will be an overlapping part between the first through groove 201b-1 and the second through groove 201d-1. At this time, the water will flow from the overlapping part to the outside of the tank, thus achieving drainage.

[0065] As the water level in the gas storage tank 100 decreases, the floating ball 202b moves downward. The floating ball 202b will not exert a pushing force on the moving rod 202d, which will then move downward, causing the moving ring 202j to move downward. At this time, the upper push block 202l will separate from the second spiral block 202i. When the lower push block 202k contacts the first spiral block 202g again, the moving ring 202j will continue to move downward, causing the lower push block 202k to move along the first spiral block 202g and causing the rotating plate 201d to rotate in the opposite direction by the same angle. At this time, the lower push block 202k contacts the first spiral block 202g, and the first through groove 201b-1 and the second through groove 201d-1 are once again in a symmetrical position. The water will not flow through the fixed plate 201b and the rotating plate 201d to the outside of the tank, and the drain pipe 201a will close again.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
