[0026] Reference Figures 1-7A Y-type filter that can be maintained online includes a discharge pipe 1, an input pipe 2, and a filter pipe 3. The filter pipe 3 is installed obliquely between the discharge pipe 1 and the input pipe 2. A filter screen 18 is fixedly installed inside the filter pipe 3, and the filter screen 18 is tightly attached to the inner wall of the filter pipe 3. A filter cylinder 16 is slidably installed inside the filter pipe 3, and the filter cylinder 16 is aligned with the axis of the filter pipe 3. A scraper ring 17 is fixedly installed at one end of the filter cylinder 16, and the scraper ring 17 is positioned between the filter cylinder 16 and the filter screen 18 and is tightly attached to the surface of the filter screen 18. A moving ring 12 is fixedly installed at the other end of the filter cylinder 16, and a sealing cover 13 is provided on the moving ring 12. Four fixing plates 4 are fixedly installed on the filter pipe 3, and support rods 7 are fixedly installed on two of the fixing plates 4. A support plate 8 is fixedly installed at one end of the support rod 7. A drive assembly is provided between the support plate 8, the moving ring 12, and the sealing cover 13. Water flows into the interior of the filter tube 3 through the input pipe 2. After being filtered by the filter screen 18 and the filter cylinder 16 inside the filter tube 3, the water enters the output pipe, thus achieving water filtration. When it is necessary to clean the impurities inside the filter tube 3, the drive assembly is activated. The drive assembly can control the sealing cover 13 and the moving ring 12 to move downward along the direction of the support rod 7. During the downward sliding of the filter cylinder 16, the scraper ring 17 on the filter cylinder 16 can scrape off the impurities on the filter screen 18, and the sealing cover 13 can be separated from the filter cylinder 16. With the flushing of the water flow, all the impurities on the filter screen 18 and the filter cylinder 16 can be flushed into the sewage pipe 20, thereby achieving remote cleaning of the filter tube 3.

[0027] As a preferred embodiment, the driving assembly includes a first screw 5 and a second screw 6 rotatably mounted on the support plate 8. Two first connecting plates 14 are provided on the moving ring 12, and two second connecting plates 15 are provided on the sealing cover 13. The first screw 5 and one of the support rods 7 pass through the two second connecting plates 15, and the second screw 6 and the other support rod 7 pass through the two second connecting plates 15. The first screw 5 and the second screw 6 are threadedly connected to the first connecting plate 14 and the second connecting plate 15, respectively. The other first connecting plate 14 and the second connecting plate 15 are slidably connected to the two support rods 7. The first screw 5 and the second screw 6 rotate simultaneously. Under the limiting action of the support rods 7, the two first connecting plates 14 and the two second connecting plates 15 can respectively drive the moving ring 12 and the sealing cover 13 to move, thereby realizing the downward separation and opening of the filter cartridge 16 and the sealing cover 13.

[0028] As a preferred technical solution in this embodiment, the pitch of the first screw 5 is greater than the pitch of the second screw 6, that is, the thread density of the first screw 5 is lower than that of the second screw 6. When the first screw 5 and the second screw 6 rotate at the same speed, the pitch of the first screw 5 is greater than the pitch of the second screw 6, which enables the sealing cover 13 to slide on the support rod 7 at a speed greater than the sliding speed of the filter cartridge 16 and the moving ring 12. This allows the sealing cover 13 to be separated from the filter cartridge 16, making it easier to clean the impurities inside the filter cartridge 16.

A protective shell is provided outside the motor 9, and a control system with network function is provided between the protective shell and the motor 9. When the remote control system transmits a signal to the control system on the motor 9, it can drive the motor 9 to operate, thereby realizing the function of online maintenance.

[0031] As a preferred technical solution in this embodiment, a sealing ring 21 is fixedly installed at the bottom end of the movable ring 12; the sealing ring 21 can increase the sealing between the movable ring 12 and the sealing cover 13.

[0032] As a preferred technical solution in this embodiment, the sealing cover 13 is provided with a sealing groove 22, and the sealing cover 13 and the sealing groove 22 are mutually sealed and adapted; the sealing ring 21 is embedded in the inner wall of the sealing groove 22, which can prevent water leakage from the filter tube 3 and increase the sealing performance of the device.

[0033] As a preferred technical solution in this embodiment, a waterproof platform 19 is fixedly installed between the motor 9 and the support plate 8; the waterproof platform 19 is raised, which can prevent impurities from remaining on the support plate 8 during the process of clearing, so that impurities and water can flow smoothly into the sewage pipe 20 for sewage discharge.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
