Description

Technical Field

[0001] The utility model relates to the field of oxygenation structures, in particular to an oxygenation structure for shrimp farming based on water stratification. Background Art

[0002] In the process of aquaculture, oxygenation equipment is needed to carry out efficient and stable oxygenation operations on the reservoirs, deep waters, rivers, fish ponds, etc. for aquaculture. This requires the use of an aerator. An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be short of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the living environment of the fish. The aerator generally relies on its own air pump to pump air into the water to achieve the purpose of increasing the oxygen content in the water.

[0003] The existing water turbine aerator uses a hub to drive blades to stir the water to increase oxygen, but the hub is fixedly connected to the blades. After long-term use, cracks will appear in the blades due to collision with other objects, causing the blades to break during use. At this time, the entire hub needs to be replaced, which increases the cost of use and is more complicated to replace. Therefore, in response to the above problems, an oxygenation structure for shrimp farming based on water stratification is proposed. Utility Model Content

[0023] The following is combined with Figure 1-5 To further explain this application in detail,

[0024] The embodiment of the present application discloses a shrimp farming oxygenation structure based on water stratification, comprising an aerator 1, a rotating shaft 2 is arranged in the middle of the aerator 1, a hub 3 is fixedly connected to the end of the rotating shaft 2, a clamping member 4 is fixedly connected to the outer wall of the hub 3, an impeller 5 is clamped in the middle of the clamping member 4, an elastic column 6 is fixedly connected to the side of the clamping member 4, the elastic column 6 is inserted into the groove of the impeller 5, and a baffle member 7 is slidably connected to the groove opened in the front of the clamping member 4;

[0025] The clamping member 4 comprises: a slot 41 and a sliding slot 42. The middle of the clamping member 4 is provided with a slot 41, and the slot 41 is plugged into the end of the impeller 5. The side of the clamping member 4 is provided with a sliding slot 42, and the sliding slot 42 is slidably connected to the end of the elastic column 6.

[0026] The impeller 5 comprises: an insert handle 51, an arc-shaped portion 511, and a positioning groove 52. The end of the impeller 5 is fixedly connected to one end of the insert handle 51, and the other side of the insert handle 51 is fixedly connected to the end of the arc-shaped portion 511. The side of the insert handle 51 is provided with a positioning groove 52, and the positioning groove 52 is engaged with an insert block at the end of the elastic column 6.

[0027] The column body of the elastic column 6 penetrates and is slidably connected to the middle of the limit frame 62, the end of the limit frame 62 is fixedly connected to the side of the clamping member 4, and the column body of the elastic column 6 is sleeved with a connecting spring 61;

[0028] The baffle member 7 comprises: a connecting plate 71, a handle 72, and an elastic clamp 73. The end of the baffle member 7 is fixedly connected to the end of the connecting plate 71, the middle of the connecting plate 71 is fixedly connected to the end of the handle 72, the upper part of the handle 72 is fixedly connected to the end of a cylinder 721, the cylinder 721 is clamped with the elastic clamp 73, and the end of the elastic clamp 73 is fixedly connected to the front part of the clamp 4.

[0029] The elastic clamp 73 further includes an opening handle 731 , and an end of the elastic clamp 73 is fixedly connected to the end of the opening handle 731 .

[0030] Working principle: When the impeller 5 breaks during the process of aerator 1 aerating water, it is necessary to stop the rotation of the rotating shaft 2, and the rotating shaft 2 drives the hub 3 to stop rotating. At this time, the handle 72 is pulled by hand, so that the handle 72 drives the cylinder 721 to break away from the clamping of the elastic clamp 73. At this time, the baffle 7 will move to the position of the handle 72, so that the baffle 7 can no longer block the plug at the end of the elastic column 6. At this time, the elastic column 6 can be pulled, and the elastic column 6 moves toward the outside, and the elastic column 6 is relieved. The plug at the end is disengaged from the positioning groove 52, so that the impeller 5 can be pulled out, and a new impeller 5 is inserted into the slot 41. The arc portion 511 will push open the plug at the end of the elastic column 6, so that the positioning groove 52 and the plug at the end of the elastic column 6 are engaged. The elastic column 6 preliminarily fixes the impeller 5. At this time, the handle 72 is pushed to make the baffle member 7 continue to block the plug at the end of the elastic column 6, and the cylinder 721 will push open the opening handle 731, so that the cylinder 721 is clamped with the elastic clamp 73.

[0031] By engaging the impeller 5 with the elastic column 6, the clamping member 4 is plugged into the impeller 5 to fix the impeller 5, thereby improving the efficiency of replacing the impeller 5. Moreover, the setting of the arc-shaped portion 511 can easily push open the elastic column 6, thereby making the plug-in process smooth. By the action of the baffle member 7, the baffle member 7 limits the plug-in block at the end of the elastic column 6, thereby preventing the impeller 5 from shaking during operation due to the looseness of the elastic column 6, thereby affecting the subsequent oxygenation.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
