The device can automatically drain water in the gas storage tank without manual labor.

[0004] However, the structure and assembly of the drainage assembly in the above patent are too complex. The probability of jamming after long-term soaking is relatively high, which can easily cause the drainage assembly to fail to operate. Moreover, the action of the drainage assembly depends on the power provided by the telescopic cylinder, which increases the probability of equipment failure and failure to realize the drainage function. Utility model content

[0005] In order to overcome the shortcomings of the prior art, the application provides a gas storage tank drainage mechanism.

[0006] The application adopts the following technical scheme: a gas storage tank drainage mechanism, comprising a first shell and a second shell. A drainage pipe is arranged on the side wall of the first shell. A water inlet pipe is arranged on the side wall of the second shell. The first shell and the second shell are butted to form a closed valve cavity. An automatic opening and closing unit is arranged in the valve cavity. The automatic opening and closing unit is used for controlling the communication or cut-off of the drainage pipe and the valve cavity.

[0007] The automatic opening and closing unit comprises a rotating seat, a rotating rod and a floating ball. The rotating seat is arranged on the inner wall of the first shell and located above the drainage pipe. The rotating rod is L-shaped. A sealing assembly is arranged on the vertical end of the rotating rod. The horizontal end of the rotating rod extends towards the second shell.

DETAILED DESCRIPTION

[0019] ​The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] like Figures 1-4 As shown, a gas storage tank drainage mechanism includes a first housing 1 and a second housing 2. A drain pipe 11 is provided on the side wall of the first housing 1, and a water inlet pipe 21 is provided on the side wall of the second housing 2. The first housing 1 and the second housing 2 can form a closed valve chamber 3 after docking. An automatic opening and closing unit 4 is provided in the valve chamber 3. The automatic opening and closing unit 4 is used to control the connection or disconnection between the drain pipe 11 and the valve chamber 3. The automatic opening and closing unit 4 includes a rotating seat 41, a rotating rod 42 and a float 43. The rotating seat 41 is provided on the inner wall of the first housing 1 and is located above the drain pipe 11. The rotating rod 42 is L-shaped. A sealing component 44 is provided at the vertical end of the rotating rod 42. The horizontal end of the rotating rod 42 extends toward the second housing 2. The float 43 is provided at the horizontal end of the rotating rod 42.

[0021] When there is no water in the valve chamber 3, the sealing assembly 44 blocks the drain pipe 11 and the float 43 is close to the lower part of the valve chamber 3. Under the action of gravity, the float 43 will exert downward pressure on the rotating rod 42, causing the vertical end of the rotating rod 42 to tend to rotate towards the drain pipe 11. This allows the sealing assembly 44 to fit tightly against the end of the drain pipe 11, preventing gas from the gas tank from escaping through the drain pipe 11. As the condensate in the valve chamber 3 gradually increases, the condensate will create buoyancy on the float 43, causing the float 43 to gradually move upward. This causes the vertical end of the rotating rod 42 to move away from the drain pipe 11, creating a gap between the sealing assembly 44 and the drain pipe 11. The condensate in the valve chamber 3 will then automatically drain out through the drain pipe 11. The structure is compact and can achieve automatic condensate drainage without additional power.

[0022] The rotating seat 41 includes a pair of upright plates 411 and a rotating shaft 412 disposed between the pair of upright plates 411. The rotating rod 42 is sleeved on the rotating shaft 412 at its corner. Each of the pair of upright plates 411 has a protruding ring 413 on its opposite side, and the protrusion of the protruding ring 413 fits against the outer wall of the rotating rod 42. The rotating rod 42 can rotate around the rotating shaft 412, thereby allowing the sealing assembly 44 to move closer to or further away from the drain pipe 11. The rotating rod 42 is held by the pair of protruding rings 413, and the contact area between the rotating rod 42 and the protruding rings 413 is small, ensuring that the rotating rod 42 can reliably rotate between the pair of upright plates 411 and preventing the rotating rod 42 from getting stuck.

[0023] The end face of the first shell 1 is provided with a first flange 12, the end face of the second shell 2 is provided with a second flange 22, the first flange 12 and the second flange 22 are provided with a sealing ring 13, and the first flange 12 and the second flange 22 are locked by a plurality of bolts 14, so that the first shell 1 and the second shell 2 are reliably butted, and the floating ball 43 and the rotating rod 42 can reliably float and rotate in the valve cavity 3, thereby ensuring the reliable automatic drainage function, and at the same time, the automatic opening and closing unit 4 can be quickly disassembled, thereby facilitating maintenance and maintenance.

[0024] The vertical end of the rotating rod 42 and the lower part of the inner wall of the first shell 1 have a distance, and the floating ball 43 is located on the inner side of the second shell 2, that is, the distance between the floating ball 43 and the rotating shaft 412 is greater than the distance between the vertical end of the rotating rod 42 and the rotating shaft 412, so that the downward pressure of the floating ball 43 on the horizontal end of the rotating rod 42 can improve the sealing effect of the sealing assembly 44 on the drain pipe 11.

[0025] The sealing assembly 44 includes a sealing head 441 and a plurality of rubber strips 442, one side of the sealing head 441 facing the rotating rod 42 is flat, the other side of the sealing head 441 facing the drain pipe 11 is arc-shaped, a plurality of rubber strips 442 are arranged on the arc-shaped side of the sealing head 441, and the elasticity of the sealing head 441 is smaller than that of the rubber strips 442. The end of the sealing head 441 facing the drain pipe 11 is arc-shaped, so that when the sealing head 441 rotates towards the drain pipe 11, the end of the sealing head 441 can be turned into the inside of the drain pipe 11, thereby improving the sealing effect on the drain pipe 11. Further, by providing the rubber strips 442 with better elasticity at the end of the sealing head 441, the gaps between the sealing head 441 and the drain pipe 11 can be filled by the larger elastic deformation of the rubber strips 442, and the sealing effect on the drain pipe 11 is significantly improved.

[0026] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of the present application.
