[0022] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, the utility model provides an aeration plate assembly, including an upper plate 1 and a lower plate 2, and a plurality of through grooves 3 are provided at corresponding positions of the opposite surfaces of the upper plate 1 and the lower plate 2, and two through grooves 3 at corresponding positions form a group, and the inner side surface of the through groove 3 is an arc surface. When the upper plate and the lower plate 2 are fitted together and fixed together, each group of through grooves forms a complete groove cavity with a cylindrical interior, and a rotatable aeration tube 4 is arranged in the groove cavity, and a plurality of evenly distributed air holes 5 are provided on the side surface of the aeration tube 4 along the length direction, and the side surface of the aeration tube is fitted with the corresponding inner wall of the groove cavity, and the aeration tube is a reducer with thin ends and thick middle, and the small diameter parts at the two ends of the aeration tube pass through the two ends of the groove cavity and are rotatably connected, and the corresponding through grooves are partially exposed on both upper and lower sides of the middle large diameter part of the aeration tube 4.

[0024] like Figure 4 As shown, one end of the aeration pipe is connected to the air inlet pipe 7 through a rotating joint 6. This design can ensure that the aeration pipe rotates without affecting the air intake. The other end of the aeration pipe is closed. The device is set in water, and the aeration pipe is rotated to make the air holes face upward and expose from the upper part of the upper through groove. Air is supplied through the air inlet pipe 7. Air can form small bubbles through the air holes to achieve the aeration function. The aeration pipe is rotated at a certain angle, and the air holes are hidden in the groove cavity, and the air holes are closed. At this time, the air supply is stopped to prevent water from flowing back into the aeration pipe.

[0025] When the device is placed in a pool and used for a long time, some impurities in the water will remain in the air holes. By rotating the aeration tube, the residue outside the air holes can be scraped off through the edge of the slot, which can play the role of cleaning the residue. By continuing to rotate the aeration tube so that the air holes face downward, increasing the air intake pressure at this time, some residues in the air holes can also be flushed out, further improving the cleaning effect.

[0026] A double-groove pulley 8 is fixedly installed on the part of one end of the aeration tube located outside the tank cavity, and two adjacent double-groove pulleys are connected by belts. This design can realize the synchronous rotation of multiple aeration tubes by rotating one aeration tube.

[0027] like Figure 1 As shown, a driving wheel 9 is installed at the end of one of the aeration tubes. The driving wheel can use a hand wheel, and the user can manually rotate the aeration tube through the hand wheel, or use a pulley or sprocket, etc., and then connect the driving wheel to a power device for electric drive (this is a prior art and will not be repeated here). It is more convenient to use and can be rotated at any time. Control.

[0028] like Figure 2 As shown, a plurality of supporting feet 10 are arranged at the bottom of the lower plate, and the device can be placed more stably on the bottom of the pool through the supporting feet, so that a certain distance is maintained between the lower plate and the bottom of the water, so as to avoid friction between the aeration pipe and the bottom of the water when rotating.

[0029] like Figure 2As shown, a plurality of lifting rings 11 are arranged on the top of the upper plate. The design of the lifting rings can facilitate the user to lift the device to the bottom of the water, and also make it more convenient to take it out from the bottom of the water.

[0030] like Figure 1 As shown, a protective cover 12 is installed at the end of the combination of the upper plate and the lower plate corresponding to the double-groove pulley, and the double-groove pulley and the rotary joint are covered by the protective cover to prevent debris from falling onto the belt and causing damage to the device during use.

[0031] like Figure 3 As shown, a sealing ring 13 is installed at the end openings away from each group of through grooves, and the inner side of the sealing ring 13 fits with the corresponding aeration pipe. This design can seal the gap between the groove cavity and the aeration pipe, and the sealing ring can also be used to better clean the side of the aeration pipe when the aeration pipe is rotated.

[0032] The device is placed in water, and the air holes are exposed upward from the upper part of the upper through groove by rotating the aeration tube, and air is supplied through the air inlet pipe 7. The air can form small bubbles through the air holes to realize the aeration function. When the aeration tube is rotated to a certain angle, the air holes are hidden in the groove cavity and are closed. At this time, the air supply is stopped to prevent water from flowing back into the aeration tube. By rotating the aeration tube, the residue outside the air holes can be scraped off through the edge of the through groove, which can play the role of cleaning the residue. By continuing to rotate the aeration tube so that the air holes face downward, the air intake pressure is increased at this time, and some residues in the air holes can be flushed out, further improving the cleaning effect. In addition, the upper plate and the lower plate of the device are installed together by combined placement, which is convenient for the combination of the device and also convenient for later disassembly and cleaning. The dense arrangement of the air holes has a good aeration effect. The surface of the device is relatively flat, and the cleaning difficulty is low, and the manufacturing difficulty is low.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
