[0002] An artificial wetland water purification device is an artificial system that imitates the principles of a natural wetland ecosystem and uses plants, soil, and microorganisms to naturally filter and purify water pollutants.

[0003] The patent with patent announcement number CN221854378U relates to an artificial wetland water purification device, including a purification pool and a purification chamber arranged inside the middle section of the purification pool, a water distribution chamber is arranged inside the left end of the purification pool, a water collection chamber is arranged inside the right end of the purification pool, and a main water inlet pipe is arranged inside the water distribution chamber near the top left end. By adding a new impurity blocking and cleaning device at the water inlet of the main water inlet pipe of the artificial wetland water purification device, the water in the artificial wetland will enter the artificial wetland water purification device through the impurity blocking and cleaning device and the main water inlet pipe. When the water passes through the impurity blocking and cleaning device, the device can block large impurities or aquatic plants in the water body outside it, so that the water body finally transported to the artificial wetland water purification device does not contain large impurities or aquatic plants, avoiding large impurities or aquatic plants from easily clogging the main water inlet pipe and water inlet seepage pipe of the artificial wetland water purification device.

[0014] The present invention provides an artificial wetland water purification device. It has the following beneficial effects:

[0015] (1) This invention pushes away the impurities accumulated at the bottom of the purification box by moving the push plate to prevent the accumulation of impurities. At the same time, the push plate will drive the L-shaped rod to move in the direction away from the motor. When the L-shaped rod moves to the end of the guide frame away from the motor, the L-shaped rod will rise along the inclined surface of the guide frame. The rise of the L-shaped rod will drive the push plate to move upward. The upward movement of the push plate will break away from the contact with the purification box. The moving frame will drive the elastic telescopic rod and the push plate to reset, so that the push plate will break away from the contact with the purification box during the reset process, thereby preventing impurities from floating freely inside the purification box and affecting the purification effect.

[0016] (2) In this invention, the push plate moves away from the motor and contacts the sliding seat, and the push plate pushes the sliding seat to move away from the motor. The sliding seat moves away from the motor and pushes the rotating rod to rotate. The rotation of the rotating rod pushes the sliding block to move downward. The downward movement of the sliding block drives the rotating plate to rotate downward. The downward rotation of the rotating plate opens the sewage outlet and discharges impurities at the bottom of the purification box to prevent the accumulation of impurities affecting the purification effect. At the same time, the downward rotation of the rotating plate drives the pulley frame to rotate downward. The downward rotation of the pulley frame pushes the trapezoidal block to move downward. The downward movement of the trapezoidal block drives the sealing connecting plate to move downward. The downward movement of the sealing connecting plate overlaps with the sealing ring to prevent a large amount of water from being discharged along with the sewage outlet when the rotating plate is opened, causing waste.

[0017] (3) This invention drives the fixed seat to move away from the motor by moving the sliding seat in the direction away from the motor, so that the liquid oxidant in the feeding box enters the purification box, which helps to decompose organic pollutants, ammonia nitrogen and sulfides in the water. At the same time, the upward movement of the sealing plate will drive the long rod to move upward, and the upward movement of the long rod will drive the rack to move upward. The upward movement of the rack will push the tooth block to rotate, and the rotation of the tooth block will drive the stirring rod to rotate, and the rotation of the stirring rod will drive the stirring blade to rotate. The rotation of the stirring blade improves the mixing effect of the liquid oxidant, and prevents the liquid from settling for a long time, which affects the purification effect.
