[0043] To make the purpose, features, and advantages of the present disclosure more obvious and understandable, the following will combine the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0044] Combined with Figure 1 and Figure 2As shown, the gas storage tank provided by the embodiment of the present disclosure includes a gas storage tank body 1. A diversion groove 2 is formed at the bottom of the gas storage tank body 1, and the diversion groove 2 extends along the axial direction of the gas storage tank body 1. A cleaning component 4 and a drainage component 3 are provided in the diversion groove 2. The cleaning component 4 includes a scraping plate 42 and a driving component. The scraping plate 42 is slidably matched with the diversion groove 2, and the driving component is arranged on the gas storage tank body 1 and connected to the scraping plate 42 for driving the scraping plate 42 to move along the axial direction of the gas storage tank body 1. The drainage component 3 is arranged in the diversion groove 2, and the drainage component 3 is provided with a water inlet 311 which is communicated with the gas storage tank body 1 for discharging the water in the diversion groove 2. When water condenses in the cavity of the gas storage tank body 1, the driving component is used to drive the scraping plate 42 to clean the water in the diversion groove 2, so that the upper surface of the diversion groove 2 is kept clean. The water in the diversion groove 2 flows along the diversion groove 2, enters the water inlet 311 of the drainage component 3 and is discharged from the drainage component 3, which can reduce the possibility that the inner wall of the gas storage tank body 1 is soaked by water for a long time and suffers from water corrosion, thereby prolonging the service life and use safety of the gas storage tank.

[0045] In some specific embodiments, a water receiving plate can be attached and installed on the lower surface of the cavity of the gas storage tank body 1. The water-saving plate forms a diversion groove 2 structure, and the cleaning component 4 is movably installed on the upper surface of the water receiving plate.

[0046] Combined Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in

[0047] In some specific embodiments, the drainage assembly 3 includes a water collecting cylinder 31 and a sewer pipe 32 which are connected to each other. The water collecting cylinder 31 communicates with the sewer pipe 32. The water collecting cylinder 31 is disposed in the diversion groove 2. Optionally, the water collecting cylinder 31 can be installed at the center position of the second V-shaped groove 22, the diversion groove 2 or the upper surface of the water receiving plate. Preferably, the water collecting cylinder 31 is installed at the lowest position of the gas storage tank body 1 to facilitate the discharge of water. The water inlet 311 is disposed on the side surface of the water collecting cylinder 31 for communicating the gas storage tank body 1 and the water collecting cylinder 31. The water inlet 311 communicates with the sewer pipe 32. The sewer pipe 32 is provided with a water outlet control assembly 33. The water in the gas storage tank can be discharged through the water outlet control assembly 33.

[0048] Optionally, the opening direction of the water collecting cylinder 31 is parallel to the horizontal bottom surface in the cavity of the gas storage tank body 1. The sewer pipe 32 is opened at the bottom of the groove of the water collecting cylinder 31, and the extending direction of the sewer pipe 32 is perpendicular to the extending direction of the diversion groove 2 of the water collecting cylinder 31. The water collecting cylinder 31 is fixedly fitted inside the gas storage tank body 1 or the diversion groove 2, and the water inlet 311 communicates with the bottom of the groove of the diversion groove 2.

[0049] Through the design of the diversion groove 2, when water condenses in the cavity of the gas storage tank body 1, it will flow towards the position where the water collecting cylinder 31 is located under the guidance of the first V-shaped groove 21 and the second V-shaped groove 22, and flow into the inner side of the water collecting cylinder 31 through the water inlet 311 for storage.

[0050] Combined Figure 2 、 Figure 3 and Figure 7 As shown in

[0051] such as Figure 8As shown in the figure, the water inlet 311 is provided with an elastic rotating plate 312. The water collecting cylinder 31 is provided with a rotating shaft. The elastic rotating plate 312 is rotatably connected to the rotating shaft. The rotating shaft is provided with a torsion spring. The two ends of the torsion spring are respectively connected to the elastic rotating plate 312 and the water collecting cylinder 31, so that the elastic rotating plate 312 blocks the water inlet 311. Regarding the condensation process of the water inside the gas storage tank body 1, it often occurs during the gas injection process. The internal air pressure gradually increases, resulting in an increase in the air temperature, thereby causing the water vapor to condense into water. As the compressed air is injected into the inner cavity of the gas storage tank body 1, the internal air pressure will increase. The increase in the pressure will overcome the elastic force of the torsion spring, causing the elastic rotating plate 312 to rotate and open, so that the water collected on the upper surface of the diversion groove 2 can smoothly flow into the water collecting cylinder 31.

[0052] Optionally, a sealing gasket 313 is fixedly arranged on one side of the elastic rotating plate 312 close to the water inlet 311, which can improve the sealing performance.

[0053] In some specific embodiments, a piston cylinder 315 is arranged inside the water collecting cylinder 31. A piston gasket 316 and an elastic member 318 are arranged inside the piston cylinder 315. The elastic member 318 can be a spring or a push spring, etc. The piston gasket 316 is slidably matched with the piston cylinder 315. The piston gasket 316 and the elastic rotating plate 312 are connected by a pull rope 317. The two ends of the elastic member 318 are respectively connected to the piston gasket 316 and the piston cylinder 315. Among them, the piston cylinder 315 is provided with a ventilation pipe 314. The ventilation pipe 314 penetrates through the water collecting cylinder 31 and is communicated with the cavity of the piston cylinder 315. A communication hole 319 is arranged in the area of the ventilation pipe 314 located inside the water collecting cylinder 31 and outside the cavity of the piston cylinder 315. Regarding the condensation process of the water inside the gas storage tank body 1, it often occurs during the gas injection process. The internal air pressure gradually increases, resulting in an increase in the air temperature, thereby causing the water vapor to condense into water. As the compressed air is injected into the inner cavity of the gas storage tank body 1, the internal air pressure will increase. The increase in the pressure will overcome the elastic force of the torsion spring, causing the elastic rotating plate 312 to rotate and open. It will also cause the piston gasket 316 inside the piston cylinder 315 to compress the elastic member 318 under the influence of the pressure, so as to promote the pull rope 317 connected to one side of it to pull the elastic rotating plate 312, and promote the elastic rotating plate 312 to maintain an open state. In this way, the water collected on the upper surface of the diversion groove 2 can smoothly flow into the water collecting cylinder 31.

[0054] In some specific embodiments, the number of the water inlets 311 and the elastic rotating plates 312 is two, and the water inlets 311 correspond to the elastic rotating plates 312 one by one; two piston pads 316 are symmetrically and slidably installed inside the piston cylinder 315, and an elastic member 318 is arranged between the two piston pads 316. A pull rope 317 is connected between the piston pad 316 and the adjacent elastic rotating plate 312. As the air pressure inside the air storage tank body 1 gradually increases, the air temperature rises, causing water vapor to condense into water. With the injection of compressed air in the inner cavity of the air storage tank body 1, the internal air pressure will increase. The increase in pressure will overcome the elastic force of the torsion spring, causing the elastic rotating plate 312 to rotate and open. At the same time, the two piston pads 316 inside the piston cylinder 315 will approach each other under the influence of the pressure, so that the pull rope 317 connected to one side of them will pull the elastic rotating plate 312, keeping the elastic rotating plate 312 in an open state. In this way, the water collected on the upper surface of the diversion groove 2 can smoothly flow into the water collecting cylinder 31.

[0055] Please refer to Figure 8 and Figure 9 As shown in FIGS. and, a ventilation pipe 314 is further connected to the upper surface of the piston cylinder 315. The ventilation pipe 314 communicates with the cavity of the piston cylinder 315. The upper end of the ventilation pipe 314 also penetrates through the upper surface of the water collecting cylinder 31. Communication holes 319 are formed on the surface of the part of the ventilation pipe 314 inside the water collecting cylinder 31. The ventilation pipe 314 can be a ventilation microporous pipe.

[0056] The formation of the communication holes 319 is used to make the internal and external pressures of the water collecting cylinder 31 tend to be consistent. The purpose of connecting the ventilation pipe 314 to the inside of the piston cylinder 315 is to allow the air outside the piston cylinder 315 to slowly enter the inside of the piston cylinder 315, so that the pressure inside the cavity of the piston cylinder 315 slowly approaches the external pressure. Its function is: by allowing the air to slowly enter the inside of the piston cylinder 315, the elastic member 318 slowly pushes the two piston pads 316 apart, and then the elastic rotating plate 312 is slowly rotated by the elastic force of the torsion spring to close the water inlet 311. In this way, after the condensed water on the upper surface of the air storage tank body 1 and the diversion groove 2 has fully entered the inside of the water collecting cylinder 31, the elastic rotating plate 312 will close the water inlet 311, and the sealing gasket 313 seals it, so that the water vapor emitted from the water in the water collecting cylinder 31 will not escape to the outside of the water collecting cylinder 31 and the cavity of the air storage tank body 1 in large quantities, causing the air in the cavity of the air storage tank body 1 to be humid, which will affect the quality of the high-pressure air on the one hand and cause corrosion of the inner wall due to the humid air on the other hand.

[0057] In some specific embodiments, the driving component includes a screw rod 41 and a first driving member. The scraping plate 42 is in threaded engagement with the screw rod 41. The first driving member is connected to the screw rod 41 and is used to drive the screw rod 41 to rotate. When water condenses in the cavity of the gas storage tank body 1, the screw rod 41 is driven to rotate by the first driving member. Since the screw rod 41 is in threaded engagement with the scraping plate 42, when the screw rod 41 rotates, the scraping plate 42 will move along the extending direction of the diversion groove 2, so that the water in the diversion groove 2 can be cleaned, and the upper surface of the diversion groove 2 can be kept clean. The water in the diversion groove 2 flows along the diversion groove 2, enters the water inlet 311 of the drainage component 3 and is discharged from the drainage component 3.

[0058] In some specific embodiments, the first driving member includes a motor. The motor is arranged on the gas storage tank body 1, and the output end of the motor is connected to the screw rod 41. By controlling the rotation of the screw rod 41 through the motor, the movement of the scraping plate 42 can be realized, so that the water in the diversion groove 2 can be cleaned. Optionally, a controller 46 is further included. The controller 46 is arranged on the gas storage tank body 1 and is connected to the motor for controlling the motor, so as to control the rotation of the screw rod 41 and realize the movement of the scraping plate 42.

[0059] Combined Figure 3 with Figure 4 As shown, the cleaning component 4 includes a scraping plate 42 slidably installed on the upper surface of the diversion groove 2, and a screw rod 41 arranged above the diversion groove 2 and in the same direction as the diversion groove 2. The screw rod 41 is rotatably installed above the diversion groove 2. The screw rod 41 is in threaded connection with the scraping plate 42. The lower surface of the scraping plate 42 is fully attached to the upper surface of the diversion groove 2. The scraping plate 42 is driven by the rotation of the screw rod 41 and slides on the upper surface of the diversion groove 2.

[0060] In some specific embodiments, a hook, a second driving member and a controller 46 are further included. The second driving member is arranged on the gas storage tank body 1. The second driving member is connected to the hook and is used to drive the hook to be clamped with the scraping plate 42. The controller 46 is connected to the second driving member for controlling the second driving member so that the hook is clamped with the scraping plate 42.

[0061] As Figure 4 shown, the cleaning component 4 further includes a controller 46 fixedly installed on the upper surface of the diversion groove 2. The controller 46 can be a timing controller 46. The controller 46 is in the same vertical plane as the end of the screw rod 41. An electrically controlled hook 45 is arranged on the side of the controller 46 close to the scraping plate 42.

[0062] After the scraping plate 42 moves to the end of the screw rod 41, the scraping plate 42 is buckled by the hook 45 to limit its position, and the controller 46 starts timing synchronously. After the timing is completed, the controller 46 controls the hook 45 to lift up to release the scraping plate 42, so that the scraping plate 42 is elastically driven by the spring coil to rotate the screw rod 41 and perform a reset sliding.

[0063] The second driving member can be a motor, and the output end of the motor is connected to the hook to control the lifting and fastening of the hook.

[0064] In actual use, the scraping plate 42 can clean the upper surface of the diversion groove 2, so that the upper surface of the diversion groove 2 remains clean, so that the water generated in the cavity of the air storage tank body 1 can smoothly flow in the first V-shaped groove 21 and the second V-shaped groove 22 of the diversion groove 2. The clamping hook 45 and the controller 46 are used to limit the reset movement of the scraping plate 42 at regular intervals to ensure that the condensed water has sufficient time to slide onto the upper surface of the diversion groove 2. After the timing of the controller 46 ends, the control clamping hook 45 releases the clamping of the scraping plate 42. The scraping plate 42 during reset can push the water stains on the upper surface of the screw 41 towards the direction of the water collecting cylinder 31 to ensure the full collection of the condensed water. The timing end time of the controller 46 should be before the time when the elastic rotating plate 312 closes the water inlet 311.
