Description
Technical Field
[0001] This invention relates to the field of landscape water treatment technology, and more specifically to a water circulation treatment device. Background Technology
[0002] Most garden landscapes use water features as their water source, replenishing soil moisture through various irrigation methods to ensure water recycling within the water feature and conserve water resources. However, since water features are set up outdoors, they are easily polluted. Over time, pollutants accumulate, leading to water quality deterioration, decreased water transparency, darkening of color, and even unpleasant odors. Current practices involve using nets to remove floating debris from the water feature, which requires a large amount of manpower to operate the nets, and the removal of impurities from the water is not thorough enough. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a water circulation treatment device that is simple in structure, reasonable in design, and easy to use. This device can not only thoroughly clean floating objects on the upper side of water features but also reduce the workload of personnel. Furthermore, impurities in the water can be cleaned simultaneously during the process of removing suspended objects, thereby improving water quality.

It also includes: A salvage assembly, wherein the salvage assembly is disposed on the upper side of the salvage frame; A swivel frame is installed inside the processing cylinder and below the liquid inlet end, and a swivel assembly is installed on the upper right side of the swivel frame. The guide frame is installed inside the processing cylinder and is located on the lower side of the sling frame. The water inlet end of the drain pipe is connected to the lower side of the guide frame. Through the above technical solution design, the salvage component drives the salvage frame to salvage floating objects; the slinger component drives the slinger frame to sling the water pumped out of the water feature, accelerating the water flow and placing the impurities inside the slinger frame.
[0005] As a further improvement of the present invention, the salvage assembly includes: A support boss is fixed on one side arm of the processing cylinder. A lifting element is provided on the support boss. A pushing element is provided on the upper side of the lifting element. Support blocks are symmetrically provided on the bottom of the pushing element. The retrieval frame is located between the two support blocks. The support shaft consists of two shafts, each fixed to the outer side of a left or right protrusion on the upper side of the retrieval frame. The outer ends of the support shafts are screwed into the corresponding support blocks via bearings. A guide gear is sleeved and fixed on one of the support shafts, positioned between the retrieval frame and the support block. A rotating gear meshes with the upper side of the guide gear, and a support shaft passes through and is fixed within the rotating gear. A rotating motor is fixed to the outer side of the support block, and its output shaft passes through the support block and connects to the support shaft. The rotating motor is connected to an external power source. Through the above technical solution design, the lifting element and the pushing element work together to drive the salvage frame and place it in the water feature; the angle of the salvage frame is adjusted by the cooperation of the rotating gear and the guide gear.
[0006] As a further improvement of the present invention, the sling assembly includes: A rotating cylinder is inserted into a spinning cylinder frame, and the hanging ring on the upper side of the rotating cylinder is in contact with the spinning cylinder frame. A rotating filter screen is installed inside the rotating cylinder. A rotating shaft is installed on the right side of the spinning cylinder frame, and the upper end of the rotating shaft is screwed onto the inner top surface of the processing cylinder body through a bearing. A rotating gear set is mounted on a rotating shaft. A rotating motor is fixed to the upper side of the processing cylinder. The output shaft of the rotating motor passes through the processing cylinder and is connected to the rotating gear set. The rotating motor is connected to an external power source. A fixing ring is sleeved on the outer side of the upper end of the rotating shaft and fixed to the inner top surface of the processing cylinder; a limit frame is provided on the outer side of the fixing ring, and the horizontal end of the limit frame is located on the lower side of the fixing ring and connected to the rotating shaft. The insertion platform consists of two platforms, symmetrically arranged on the left and right sides. The insertion platforms pass through the vertical end of the limiting frame from the outside to the inside and are then inserted into the fixing ring. A left drive frame is provided in front of the insertion platform on the left side, and a right drive frame is provided in front of the insertion platform on the right side. Both the left and right drive frames are arranged in an "L" shape. A fixed frame is located on the front side of the limiting frame and is connected to the inner top surface of the processing cylinder via two connecting bosses on its upper side. The transverse end of the left drive frame slides through the front open end of the fixed frame, and the transverse end of the right drive frame slides through the rear open end of the fixed frame.

The drive motor is connected to an external power source. Through the above technical solution design, the rotation of the drive gear causes the racks on the front and rear sides to move in opposite directions, thereby moving the left drive frame and the right drive frame. When the insertion platform is in the vertical end of the limiting frame and inside the fixed ring, the rotating shaft is limited. When the insertion platform is away from the fixed ring and the vertical end of the limiting frame, the rotating shaft can rotate.

[0009] As a further improvement of the present invention, a drive handle is provided on the upper side of the processing cylinder.
[0010] The above technical solution design facilitates the driving operation of the processing cylinder.
[0011] The working principle of this invention is as follows: The processing cylinder is placed on the bank of a water feature. The lifting and pushing components work together to adjust the retrieval frame, placing it within the water feature. The angle of the retrieval frame is adjusted by rotating gears meshing with guide gears, making it easier to collect floating debris. The processing cylinder is moved manually by holding the drive handle, allowing the retrieval frame to perform retrieval operations within the water feature. During the movement of the processing cylinder, in addition to the retrieval frame collecting floating debris, a water pump draws water from the water feature and discharges it to the inlet. The water is then filtered through a filter screen inside the guide frame, placing larger impurities on the screen. The water flows into the rotating filter screen inside the rotating cylinder and finally flows through the guide frame to the drain pipe for discharge. The rotating shaft is limited and the retrieval frame is fixed by inserting the insertion platform into the vertical end of the limiting frame and the fixing ring. After all the water has been filtered, the insertion platform is disengaged from the fixing ring and the vertical end of the limiting frame. The rotating gear set then drives the retrieval frame to rotate, causing the water contained in the impurities in the rotating filter screen to flow downwards.
[0012] With the above structure, the beneficial effects of the present invention are as follows: 1. The retrieval frame is set on one side of the processing cylinder. During the process of driving the processing cylinder, the retrieval frame is driven to perform the retrieval operation, avoiding the need to manually retrieve the retrieval net. 2. While handling the movement of the cylinder, in addition to retrieving floating objects, it can also filter impurities inside the water feature. 3. By using a filter screen and a rotating filter screen, impurities in the water are filtered out, reducing the impurity content and improving water quality. Attached Figure Description
