If the dissolved oxygen concentration of the water quality is not changed in time, the water body will enter a vicious cycle, with more algae, turbid water, low transparency, and then black and smelly. In order to restore the biodiversity of rivers and lakes and solve the hypoxia of water bodies, the water quality needs to be quickly enriched and oxygenated.

[0032] One end of the central shaft 9 is fixedly mounted on the water inlet base 7 , and the other end passes through the cavity 4 and is sleeved through the first copper sleeve 10 to be connected and rotated with the end cover 11 ; the impeller 3 is fixedly sleeved on the central shaft 9 .

[0033] See also Figure 3 As shown, in some embodiments, a keyway is provided on the central shaft 9, and a key connection is achieved with the impeller 3 through a key 2. A circlip groove is provided on the central shaft 9, and a circlip connection is achieved with the impeller through a circlip 1. That is, the impeller 3 is fixed to the central shaft 9 through the key 2 and the circlip 1.

[0034] See also Figure 1 As shown, the rotary joint 6 is arranged between the cavity 4 and the water inlet base 7. The water inlet base 7 is connected to the rotary joint 6 by bolts, and the other end of the rotary joint 6 is connected to the cavity 4 by bolts.

[0035] A fixed flange is arranged between the rotary joint and the water inlet base; and a rotatable flange is arranged between the rotary joint and the cavity.

[0036] Embedded sealing gaskets 5 are respectively provided at the upper and lower connections between the rotary joint 6 and the water inlet base 7 and the cavity 4 .

[0037] A second copper sleeve 13 is arranged between the impeller 3 and the cavity 4 .

[0038] The shaft 9 is coaxially matched with the cavity 4 , the end cover 11 , the impeller 3 , the rotary joint 6 , and the water inlet base 7 .

[0039] The hydraulic self-rotating reoxygenation nozzle is designed with an integrated coaxial structure of a cavity 4, an impeller 3, a rotary joint 6 and a water inlet base 7. Based on the structure that the impeller 3 and the water inlet base 7 are fixedly connected to the central axis 9, centrifugal force is generated when the oxygen-enriched water enters the impeller 3 after passing through the rotary joint 6. By utilizing the fixed characteristic of the impeller 3, the cavity 4 is subjected to the centrifugal force in the opposite direction to rotate relative to the impeller 3, driving the water outlet 12 to rotate and spray out the oxygen-enriched water. The impeller 3 structure is cleverly used in the reverse direction to realize the hydraulic self-rotation of the cavity 4, and then realize the self-rotation spraying of the water outlet 8.

[0040] The working principle of the hydraulic self-rotating reoxygenation nozzle provided by the utility model is:

[0041] Oxygen-enriched water with a certain flow rate and pressure enters through the water inlet 12, and then enters the center of the impeller 3 after passing through the inside of the rotary joint 6, and enters the cavity 4 through the circumference of the impeller 3 and is sprayed toward the water outlet 8. That is, centrifugal force is generated when the oxygen-enriched water passes through the impeller 3. Because the impeller 3 is fixed to the central axis 9 and the central axis 9 is fixedly connected to the water inlet base 7, the water inlet base 7 is fixed in the natural water body and is guaranteed to be unable to rotate. The cavity 4 is connected to the rotary joint 6, so that the cavity 4 is subjected to the centrifugal force in the opposite direction, causing the cavity 4 to rotate relative to the impeller 3. Because the impeller 3 cannot rotate, the cavity 4 drives the water outlet 8 to rotate and spray out the oxygen-enriched water, thereby realizing that the ultra-nano gas-dissolved oxygen-enriched water in the natural water body quickly merges with the surrounding natural water body through self-rotation spraying, increasing the reoxygenation radius, accelerating the reoxygenation efficiency, reducing the cost, and simplifying the system control.

[0042] In summary, the utility model provides a hydraulic self-rotating reoxygenation nozzle, which includes a cavity, a water outlet connected to the cavity, an impeller arranged inside the cavity, a rotating joint, a water inlet base, a water inlet connected to the water inlet base, and a central axis; one end of the central axis is fixedly mounted on the water inlet base, and the other end passes through the cavity and is connected to the top of the cavity; the impeller is fixedly mounted on the central axis. The rotating joint is arranged between the cavity and the water inlet base. The central axis is concentrically matched with the cavity, the end cover, the impeller, the rotating joint, and the water inlet base. The utility model realizes that ultra-nano aerosolized oxygen-rich water in natural water bodies can be quickly integrated with the surrounding natural water bodies through self-rotating injection, thereby increasing the reoxygenation radius, accelerating the reoxygenation efficiency, reducing the cost, and simplifying the system control. Therefore, the technical defects of the existing technology of small reoxygenation radius and single injection direction of oxygen-rich water are effectively overcome.

Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
