[0022] As Figures 1-4 shown, it relates to an underwater fixing device for a microporous aerator, including a lifting assembly 1, a support assembly 2 and a cross plate 4. The support assembly 2 is fixed to the bottom of the sewage tank. One end of the cross plate 4 is fixedly connected to the moving end of the lifting assembly 1. A plurality of installation assemblies 5 for installing the aeration pipe are fixedly arranged on the lower surface of the cross plate 4. The top of the lifting assembly 1 is fixedly provided with a driving assembly 3, and the driving assembly 3 drives the moving end of the lifting assembly 1 to move up and down.

[0023] The support assembly 2 includes a support plate 21. A plurality of arc grooves 22 for clamping the aeration pipe are equidistantly arranged on the upper surface of the support plate 21. Installation plates 23 are fixedly arranged at both ends of the support plate 21.

[0024] The support plate 21 can be fixed to the bottom of the tank body through the installation plate 23, and the arc groove 22 can play a limiting role on the aeration pipe.

[0025] The installation assembly 5 includes a U-shaped block 51 fixed to the lower surface of the cross plate 4, and the aeration pipe is located in the groove at the bottom of the U-shaped block 51. The side wall of the U-shaped block 51 penetrates and is threadedly connected with a locking bolt 52. A plurality of installation assemblies 5 are respectively located directly above a plurality of arc grooves 22.

[0026] After the aeration pipe is clamped into the inside of the U-shaped block 51, the aeration pipe can be squeezed by tightening the locking bolt 52, so that the aeration pipe is fixed inside the U-shaped block 51. When the cross plate 4 moves up and down, the aeration pipe can be driven to move up and down synchronously.

[0027] The lifting assembly 1 includes a guide rail 11 which is vertically fixed on the inner wall of the pool body. A vertical chute 12 is formed on the surface of the guide rail 11. A slider 13 is slidably connected inside the chute 12. A lead screw 15 is rotatably connected inside the chute 12 through a bearing. The lead screw 15 passes through the slider 13 and is threadedly connected to the slider 13.

[0028] When the lead screw 15 rotates forward or backward, the lead screw 15 can drive the slider 13 to move up or down along the chute 12, and the cross plate 4 fixedly connected to the slider 13 will move synchronously. In this embodiment, the lead screw 15 and the slider 13 are made of stainless steel.

[0029] An installation groove 14 is formed at one end of the slider 13 outside the chute 12. The cross plate 4 is fixed inside the installation groove 14 by bolts. Therefore, the cross plate 4 can be disassembled and replaced.

[0030] The driving assembly 3 includes a box body 31 fixed on the top of the guide rail 11. The top end of the lead screw 15 extends into the box body 31 and is fixedly connected with a driven bevel gear 32. A horizontal shaft 33 is rotatably connected inside the box body 31. A driving bevel gear 34 and a driven spur gear 35 are fixed on the surface of the horizontal shaft 33. The driving bevel gear 34 meshes with the driven bevel gear 32. A driving shaft 36 is rotatably connected to the side wall of the box body 31 near the driven spur gear 35 through a bearing. Two ends of the driving shaft 36 are respectively fixedly connected with a driving spur gear 37 and a turntable 38. The driving spur gear 37 meshes with the driven spur gear 35.

[0031] Rotating the turntable 38 can drive the driving spur gear 37 to rotate. The driving spur gear 37 then drives the driven spur gear 35 to rotate. The driving bevel gear 34 coaxial with the driven spur gear 35 then drives the driven bevel gear 32 to rotate, and finally the lead screw 15 rotates. Therefore, when driving the cross plate 4 to move up and down, it is only necessary to rotate the turntable 38 on the top of the pool body.

[0032] The diameter of the driving spur gear 37 is larger than that of the driven spur gear 35. By driving a small gear with a large gear, the speed ratio can be increased, thereby increasing the lifting speed of the cross plate 4.

[0033] Working principle: When fixing the aeration pipe, first fix the support assembly 2 to the bottom of the pool body through the mounting plate 23, then fix the aeration pipes in the grooves at the bottoms of a plurality of U-shaped blocks 51 respectively, and then drive the slider 13 and the cross plate 4 to descend by rotating the turntable 38 until the aeration pipes are clamped into the arc-shaped grooves 22 of the support assembly 2. When the aeration pipes need to be repaired, rotate the turntable 38 in the reverse direction on the top of the pool body to drive the cross plate 4 to rise to the water surface.
