Detailed Description

As shown in figures 1-7, the utility model comprises a guide rail frame 1 and a drawer type aeration component 2.

As shown in fig. 2, the track frame 1 includes a stainless steel rotating shaft 3, side frame bars 4 hinged at both ends of the rotating shaft 3 and parallel to each other, and a plurality of connecting rods 5 connected between the two side frame bars 4. The stainless steel shaft 3 is fixed to the bottom of the aeration tank 20 (see fig. 6) and serves as a shaft around which the frame is integrally rotated. The side frame rod 4 comprises an Contraband-shaped channel steel 6 and a straight tubular guide rail 7 (shown in figure 5) axially arranged in the channel steel 6, one end of the channel steel 6 is hinged with the rotating shaft 3 through a bearing, and a guide rail lifting lug 8 and a nut 9 are arranged at the other end of the channel steel 6. A steel wire rope 19 is connected to the guide rail lifting lug 8 in a penetrating manner, and the steel wire rope 19 is connected with a lifting device outside the pool; the nut is used for matching with the bolt to fix the aeration component 2.
