DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 As shown, a sewage treatment aerator comprises a float 1; an aeration device body 2 is sleeved on the outer side of the float 1, a nozzle 3 is fixedly connected to the top of the float 1, and a connection mechanism is provided between the float 1 and the aeration device body 2;

[0025] The connecting mechanism includes a connecting seat 41, and the connecting seat 41 is inserted into the inside of the connecting groove 42. The connecting groove 42 is opened at the top of the buoy 1. The bottom end of the connecting groove 42 is opened with a movable groove 48. The inside of the movable groove 48 is fixedly connected with a sliding rod 49. The outer side of the sliding rod 49 is wound with a spring 50, and the outer side of the sliding rod 49 is also sleeved with a slider 51. The top of the slider 51 is fixedly connected with a clamping block 52, and the clamping block 52 passes through the clamping groove 53 and is clamped with the clamping groove 53. The clamping groove 53 is opened at a position close to the center of the connecting seat 41. The end of the spring 50 close to the slider 51 is fixedly connected to the slider 51, and the end of the spring 50 away from the slider 51 is fixedly connected to the inner wall of the movable groove 48. The clamping block 52 is hook-shaped, and the top of the clamping block 52 is opened with an inclined surface.

[0026] The existing sewage treatment aerator sucks in sewage through a water pump, and then sprays the sewage from the top of the device so that air and sewage can be fully mixed. The water pump is generally installed on a float. However, the existing sewage treatment aerator is inconvenient to install and needs to be combined with special tools and connectors. When working, when the aeration device body 2 and the nozzle 3 are to be connected with the float 1, the connecting seat 41 is first inserted into the interior of the connecting groove 42. When the connecting seat 41 is inserted into the interior of the connecting groove 42, the bottom end of the positioning block 43 provided on the connecting seat 41 is aligned with the bottom end of the card block 52. The inclined surface produces extrusion, so that the block 52 moves under the action of the extrusion force, and drives the fixedly connected slider 51 to move synchronously inside the movable groove 48, and at the same time squeezes the spring 50 to cause the spring 50 to produce elastic deformation. When the connecting seat 41 is fully inserted into the connecting groove 42, the extrusion force of the positioning block 43 on the block 52 disappears. At this time, the slider 51 returns to its original position under the action of the restoring force of the spring 50, and drives the block 52 to move synchronously to its original position, so that the block 52 is engaged with the groove 53, and the connecting seat 41 is fixed, so that the aeration device body 2 and the nozzle 3 are connected to the float 1.

[0027] Furthermore, the left and right sides of the inner wall of the connecting groove 42 are fixedly connected with positioning blocks 43, and the positioning blocks 43 are matched with the positioning grooves 44, and the positioning grooves 44 are provided on both sides of the connecting seat 41;

[0028] During operation, when the connecting seat 41 is inserted into the connecting groove 42, the positioning block 43 is simultaneously inserted into the positioning groove 44. The combination of the positioning block 43 and the positioning groove 44 guides the connecting seat 41, thereby preventing the connecting seat 41 from getting stuck due to friction with the inner wall of the connecting groove 42 when being inserted into the connecting groove 42.

[0029] Furthermore, a magnetic block 45 is fixedly connected to the bottom end of the inner wall of the connecting groove 42, and the magnetic block 45 is attracted to the cast iron block 46; the cast iron block 46 is fixedly connected to the inside of the fixing groove 47, and the fixing groove 47 is opened at the bottom end of the connecting seat 41 near the buoy 1;

[0030] During operation, after the connecting seat 41 is inserted into the connecting groove 42, the magnetic block 45 is also inserted into the fixing groove 47 and is attracted to the fixing groove 47. The combination of the magnetic block 45 and the cast iron block 46 plays an auxiliary fixing effect on the connecting seat 41, so that the connection between the aeration device body 2 and the nozzle 3 and the float 1 is more stable.

[0031] Working principle: When the aeration device body 2 and the nozzle 3 are to be connected to the buoy 1, the connecting seat 41 is first inserted into the connecting groove 42. When the connecting seat 41 is inserted into the connecting groove 42, the bottom end of the positioning block 43 provided on the connecting seat 41 squeezes the inclined surface provided at the bottom end of the clamping block 52, so that the clamping block 52 moves under the action of the squeezing force, and drives the fixedly connected slider 51 to move synchronously in the movable groove 48, and at the same time squeezes the spring 50 to cause the spring 50 to produce elastic deformation. When the connecting seat 41 is fully inserted into the connecting groove 42, the squeezing force of the positioning block 43 on the clamping block 52 disappears. At this time, the slider 51 returns to its original position under the action of the restoring force of the spring 50, and drives the clamping block 52 to move synchronously to its original position, so that the clamping block 52 is engaged with the clamping groove 53, and the connecting seat 41 is fixed, so that the aeration device body 2 and the nozzle 3 are connected to the buoy 1.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, similar improvement, etc. made within the theoretical and principle content of the utility model shall be included in the protection scope of the utility model.
