[0024] In order to drive the scraper rod 33, a driving rack 34 is fixedly connected to the inner side wall of the movable groove, and the side wall surface of the driving rack 34 is meshed with the surface of the movable gear 32 through a toothed engagement. While the driving gear 37 is used to promote the rotation of the movable gear 32, it is convenient to movably install the movable plate 31 through the movable gear 32 and the scraper rod 33. An additional limit block can also be installed on the surface of the movable plate 31, and the surface of the limit block is limited by the inner wall of the movable groove, so as to facilitate the limitation of the running path of the movable plate 31. A transmission mechanism 35 is fixedly inserted on the upper end surface of the lifting well pipeline 1, and a mounting plate 36 is fixedly connected to the lower end side wall surface of the transmission mechanism 35. The lower end of the transmission mechanism 35 is connected to a driving gear 37 through a rotating shaft transmission. The driving gear 37 and the transmission mechanism 35 are respectively located on both sides of the mounting plate 36. The transmission mechanism 35 includes a shell, a pulley and a transmission belt. The transmission belt is used to transmit the two pulleys inside the shell, so that the two ends of the transmission mechanism 35 are transmitted through the pulleys.

[0025] In order to increase the sweeping range of the scraper rod 33, a transmission gear 38 is rotatably connected to the side wall surface of the mounting plate 36 through a rotating shaft. The two transmission gears 38 are respectively located on both sides of the driving gear 37 and mesh with the surface of the driving gear 37. The surfaces of the two transmission gears 38 are fixedly connected with fan plates 39. The outer surface of the fan plate 39 and the outer surfaces on both sides of the movable plate 31 are provided with latch teeth. The outer surface of the fan plate 39 and the outer surfaces on both sides of the movable plate 31 are meshed with latch teeth. The two fan plates 39 are installed in completely consistent positions on the surfaces of the two transmission gears 38, so that when the two transmission gears 38 rotate, at most only one fan plate 39 is in contact with the surface of the movable plate 31 at the same time.

[0026] By installing a primary filtering mechanism in the lifting well pipeline 1 and at the front end of the filter element 2, the filter screen 3 in the primary filtering mechanism is used to filter the impurities in the lifting well pipeline 1. At the same time, a scraper rod 33 is installed on the surface of the filter screen 3, and the scraper rod 33 is used to sweep the impurities on the surface of the filter screen 3 to ensure the smooth flow of the surface of the filter screen 3. The scraper rod 33 is driven to slide up and down on the movable plate 31 to further increase the sweeping range of the scraper rod 33, thereby facilitating the long-term use of the filter screen 3.

A waterproof motor can also be selected to install the entire primary filtration mechanism inside the lifting well pipeline 1, and an additional fixing structure is set to install and fix the mounting plate 36 to reduce the pressure on the transmission mechanism 35.

[0028] Working principle:

[0029] When in use, the drive motor 4 is started, and the drive motor 4 drives the drive gear 37 to rotate through the transmission mechanism 35, and the drive gear 37 drives the two fan plates 39 to rotate respectively through the two transmission gears 38;

[0030] When one of the fan plates 39 rotates and contacts one side surface of the movable plate 31, and pushes the movable plate 31 upward, the movable plate 31 pushes the scraper rod 33 upward through the movable gear 32, and the movable gear 32 slides upward on the surface of the driving rack 34, and the movable gear 32 rotates and drives the scraper rod 33 to deflect;

[0031] As the transmission gear 38 continues to rotate, the fan plate 39 in contact with the surface of the movable plate 31 switches, and the other fan plate 39 pushes the movable plate 31 down. The movable gear 32 slides downward on the surface of the driving rack 34, and the movable gear 32 rotates and drives the scraper rod 33 to deflect in the opposite direction. The reciprocating deflection of the scraper rod 33 scrapes off the impurities on the surface of the filter screen 3, keeping the surface of the filter screen 3 unobstructed.
