[0002] For surface water bodies such as rivers and lakes near residential areas and villages, the discharge of domestic sewage, rainwater carrying sludge in the rainwater pipe network, and long-term discharge of sewage from rural farmland and breeding sites have led to eutrophication of these surface water bodies, making them prone to algal blooms. This is accompanied by the death of plants and animals in the water, which harms the original ecological environment.

[0003] There are various methods for purifying surface water bodies, one of which involves adding chemical solutions to the water to purify it.

[0004] In existing technologies, the methods of adding chemicals are generally carried out by manual spraying or by placing the chemical solution at fixed points and letting it naturally dilute with the water flow into the water body. However, in the initial stage, the chemical solution added by this method is only distributed in a certain area of ​​the water body. As the chemical solution spreads, the chemical solution content in different locations of the water body is uneven, resulting in uneven water purification and affecting the overall purification effect.

[0005] Therefore, the inventors have provided a dosing device for water purification in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in traditional water purification processes, the added chemicals cannot be evenly distributed in the water, resulting in uneven chemical content in different locations of the water and affecting the overall purification effect.

The floating platform is also provided with a rotatable nozzle and a drive structure for driving the nozzle to rotate. The mixing structure is connected to the medicine tank and the nozzle respectively through a medicine inlet pipe and a liquid outlet pipe, and is also connected to a water guide pipe extending below the water body for introducing water. The floating platform is respectively provided with a medicine inlet pump, a liquid outlet pump, and a water guide pump for controlling the connection of the medicine inlet pipe, the liquid outlet pipe, and the water guide pipe.

[0008] Furthermore, the medicine tank is fixed to the bottom surface of the floating platform, and the floating platform has a medicine addition port that communicates with the inner cavity of the medicine tank.

[0009] Furthermore, the drive structure includes a rotating shaft rotatably connected to the floating platform, a drive motor fixedly connected to the floating platform, and a transmission mechanism connected between the rotating shaft and the output shaft of the drive motor, with the nozzle fixedly connected to the top of the rotating shaft.

[0010] Further, the spray head is fixed to the top end of the rotating shaft and is inclined to one side.

[0011] Further, the medicine inlet pump, the liquid outlet pump and the water guide pump are all peristaltic pumps, and the medicine inlet pump, the liquid outlet pump and the water guide pump are all coaxially fixed to the rotating shaft.

[0012] Further, the rotating shaft is provided with a through hole, the top of the through hole is communicated with the spray head, and the bottom of the through hole is rotationally connected with and communicated with the liquid outlet pipe.

[0013] Further, the cross-sectional area of the liquid outlet pipe is equal to the sum of the cross-sectional areas of the medicine inlet pipe and the water guide pipe.

[0014] The principle and effect of the scheme are that:

[0015] Compared with the prior art, the medicine liquid and the water body are guided into the medicine mixing structure by the medicine inlet pump and the water guide pump, mixed, guided into the spray head by the liquid outlet pump, sprayed out by the spray head, and rotated by the driving structure, so that the water body in the circular range with the spray head as the center and the spraying distance as the radius uniformly receives the medicine liquid, and the problem that the added medicine liquid cannot be uniformly distributed in the water body in the traditional water body purification process, the medicine liquid content in the water body at different positions is not uniform, and the overall purification effect is affected is solved.
