Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 4 , the present invention provides a compressed air storage tank drainage device, including a drainage cylinder 1 and an extrusion tank body 2 communicated on both sides of the drainage cylinder 1. A water-absorbing sponge 14 is arranged in the extrusion tank body 2. The water-absorbing sponge 14 is connected with an extrusion mechanism for extruding the water-absorbing sponge 14. The extrusion mechanism includes a supporting plate 16, a pressure sensor 17, an extrusion plate 9, a lifting plate 13, and a cylinder 6. The cylinder 6 is used to drive the lifting plate 13 to lift and lower. The supporting plate 16 is connected to the lifting plate 13. The pressure sensor 17 is connected to the top of the supporting plate 16. The extrusion plate 9 is connected to the pressure sensor 17. The lifting plate 13 is connected with a plugging structure for plugging the connecting pipe 4 and the drain pipe 5.

[0020] The drainage end of the storage tank is connected to the connecting pipe 4. At this time, the upper plug 10 is separated from the connecting pipe 4. The water in the storage tank flows into the drainage cylinder 1. The two water-absorbing sponges 14 absorb the water. The pressure sensor 17 can detect the pressure change. When the preset pressure is reached, the cylinder 6 can drive the lifting plate 13 to move upward, synchronously driving the two supporting plates 16 to move upward, so that the extrusion plate 9 squeezes the water-absorbing sponge 14. At this time, the lower plug 18 is separated from the drainage groove 19, and the water automatically drains out from the drain pipe 5. At the same time, the two guide posts 11 move upward synchronously, and the spring 12 is compressed, so that the upper plug 10 presses tightly against the connecting pipe 4, realizing the plugging of the connecting pipe 4, and avoiding the leakage of high-pressure gas in the storage tank during the drainage process, making it safe and reliable to use.

[0021] The extrusion mechanism further includes a connecting block 22. Both ends of the connecting block 22 are fixedly connected to the supporting plate 16 and the lifting plate 13, and the connecting block 22 is slidably connected to a rectangular hole 15 arranged inside the extrusion tank body 2. When the lifting plate 13 moves up and down, the connecting block 22 slides in the rectangular hole 15, which can improve the stability of the lifting and lowering of the lifting plate 13 and the supporting plate 16.

[0022] A plurality of round holes 20 are formed in the inner side of the extrusion tank body 2. The round holes 20 and the rectangular holes 15 facilitate the absorption of water by the water-absorbing sponge 14. When the water-absorbing sponge 14 is extruded, water can be discharged from the round holes 20 and the rectangular holes 15, which can serve as the inlet and outlet channels for water.

[0023] The sealing structure includes an upper plug 10, two guide posts 11, two springs 12, two spring seats 21, two lower plugs 18, and two connectors 23. The connector 23 is slidably connected to the guide post 11. The spring seat 21 is fixed to the guide post 11. The spring 12 is sleeved on the guide post 11, and both ends of the spring 12 are connected to the connector 23 and the spring seat 21. The connector 23 is fixedly connected to the upper plug 10. The lifting plate 13 is used to drive the two guide posts 11 to lift and lower synchronously. The lower plug 18 is connected to the bottom of the lifting plate 13. During normal operation, the lifting plate 13 is connected to the inner bottom end of the drainage cylinder 1. At this time, the lower plug 18 presses tightly against the drainage groove 19, which can prevent water from flowing out of the drainage pipe 5 along the drainage groove 19, making the space inside the drainage cylinder 1 a closed space. And the upper plug 10 and the connecting pipe 4 are in a separated state, which facilitates the smooth flow of water in the storage tank into the drainage cylinder 1 through the connecting pipe 4.

[0024] When draining water, the lifting plate 13 rises, separating the lower plug 18 from the drainage groove 19, realizing the conduction of the drainage pipe 5, and facilitating the discharge of water from the drainage pipe 5. At the same time, the rising of the lifting plate 13 synchronously drives the two guide posts 11 to rise, drives the two spring seats 21 to rise, and the spring 12 is gradually compressed. The upper plug 10 presses tightly against the connecting pipe 4, realizing the sealing of the connecting pipe 4, and avoiding the leakage of high-pressure gas in the storage tank during the drainage process, making it safe and reliable to use.

[0025] A sealing surface 8 is provided on the outer side of the upper plug 10, which can improve the sealing performance when connected to the connecting pipe 4.

[0026] A drainage groove 19 is formed at the bottom of the drainage cylinder 1. The drainage groove 19 is matched with the lower plug 18, and the drainage groove 19 communicates with the drainage pipe 5. Both the lower plug 18 and the upper plug 10 are frustum-shaped structures, which improve the sealing performance when connected to the corresponding drainage groove 19 and connecting pipe 4.

[0027] A guide groove 7 is provided inside the connecting pipe 4. The guide post 11 is slidably connected to the guide groove 7. When the lifting plate 13 is lifted and lowered, the guide post 11 slides in the guide groove 7. With the use of the connecting block 22, the stability of the lifting and lowering of the lifting plate 13 is improved, facilitating the docking of the lower plug 18 with the drainage groove 19, and the upper plug 10 can accurately press on the connecting pipe 4.

[0028] A sealing door 3 is detachably connected to the side of the extrusion tank body 2. The detachable connection is a bolt connection, and the sealing door 3 can be regularly opened to facilitate the disassembly and replacement of the water-absorbing sponge 14.

[0029] Working principle: The water-absorbing sponge 14 absorbs water, and its weight increases accordingly, and the detected value of the pressure sensor 17 also increases accordingly. When the preset value is reached, the cylinder 6 drives the lifting plate 13 to move upward, synchronously driving the two support plates 16 and the two extrusion plates 9 to move upward, so that the extrusion plate 9 squeezes the water-absorbing sponge 14. At this time, the lower plug 18 is separated from the drainage groove 19, and the drain pipe 5 is in a conducting state. After extrusion, the water is discharged from the drain pipe 5. At the same time, the two guide posts 11 move upward synchronously, driving the two spring seats 21 to move upward, and the spring 12 is gradually compressed. The upper plug 10 presses tightly against the connecting pipe 4 to block the connecting pipe 4, thereby avoiding the leakage of high-pressure gas in the storage tank during the drainage process, and the use is safe and reliable. After the drainage is completed, the cylinder 6 drives the lifting plate 13 to move downward, synchronously driving the two support plates 16 and the two extrusion plates 9 to move downward and return to their original positions. The lower plug 18 presses tightly against the drainage groove 19, making the inside of the drainage cylinder 1 in a closed space to avoid potential leakage hazards. Further, the two guide posts 11 move downward synchronously, the spring 12 returns to its original position, and the upper plug 10 returns to its original position and separates from the connecting pipe 4. At this time, the connecting pipe 4 is in a conducting state, facilitating the water in the storage tank to flow into the drainage cylinder 1 through the connecting pipe 4, and the water-absorbing sponge 14 absorbs water again, and the operation is flexible and convenient.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
