[0002] Eutrophic ecological ponds, due to excessive nutrients such as nitrogen and phosphorus, can lead to an explosive proliferation of algae. By using filtration devices to physically intercept these substances, suspended solids and organic pollutants in the water can be removed, preventing the water from becoming turbid, green, or even smelly. To achieve better filtration results, a stepped filtration device is required.

[0003] Meanwhile, the ecological pond filtration system with application number CN202422144333.3 includes a water collection unit, a sedimentation and filtration unit, a sterilization chamber, and a circulating water pump. The water collection unit includes a surface water pipe and a bottom water pipe, one end of which is connected to the surface and bottom of the pond, respectively. The sedimentation and filtration unit includes a sedimentation chamber and a filtration chamber. In actual operation of this utility model, by starting the circulating water pump, the surface water pipe and the bottom water pipe can input water from the surface and bottom of the pond into the sedimentation chamber, which facilitates the absorption of fish feces and impurities at the bottom of the pond, as well as aquatic plants or impurities floating on the surface. The rotary drum filter can filter impurities from the water source, improving the cleanliness of the water source. The filtered water source enters the sterilization chamber, where a matrix ultraviolet generator sterilizes and disinfects the water source. Finally, the water is output back into the pond, completing the water circulation.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing device can efficiently filter pool water, it requires manual installation when placing the submersible pump, which makes the installation time-consuming and labor-intensive, affecting the overall filtration efficiency.

A mounting frame is installed on the top rear side of the filter box, and a stepper motor is installed on the top of the mounting frame. The output end of the stepper motor passes through the mounting frame and is coaxially connected to a lead screw. A nut is installed on the side wall of the lead screw, and a connecting block is fixedly sleeved on the side wall of the nut. A connecting frame is installed on the rear side of the connecting block, and a submersible pump is installed on the bottom inner side of the connecting frame. A connecting pipe is installed on the output end of the submersible pump and the upper rear side of the filter box, and a flexible hose is connected between the two connecting pipes.

[0007] Preferably, the stepped filtration mechanism includes multiple filter housings supported side by side inside the filter box and filter holes evenly opened at the bottom of the filter housings, and the inner side of the filter housings is filled with filter media.

[0008] Preferably, the front and rear outer walls of the filter housing are constructed with grooves, and the edges of the grooves are arc-shaped.

[0009] Preferably, the filter box has a door hinged to the front side, and the door is supported on the front side of the filter housing.

[0010] Preferably, a latch is installed between the door and the corresponding side of the filter box, a drain pipe is inserted into the lower front part of the door, and a flange is welded to the front end of the drain pipe.

[0011] Preferably, the filter box is equipped with four wheels with braking function at the bottom corners, and handles are connected to the left and right outer walls of the filter box.

[0012] Preferably, two inclined support plates are connected side by side between the mounting frame and the filter box, and the ecological pond is surrounded by earthen slopes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a stepper motor to drive the lead screw to rotate, which controls the lifting and lowering of the connecting frame behind the nut. The submersible pump located inside the connecting frame can then be automatically placed at the bottom of the ecological pond without manual placement. This makes the placement of the submersible pump simple and convenient, and the overall filtration efficiency is higher.
