[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] Please see Figures 1-5 The utility model proposes a sewage treatment device for an engineering area, including a shell 1, an inlet pipe 2 at the upper end of the shell 1, a baffle 13 directly above the lead screw 51, the baffle 13 being fixedly connected to the inner wall of the shell 1, a drain pipe 3 at the lower end of the shell 1, a filter screen 4 being fixedly connected to the inner wall of the shell 1, and a cleaning device on the shell 1.

[0028] In an embodiment of the utility model, in order to clean the filter screen 4, the cleaning device specifically includes a servo motor 50, which is fixedly connected to the outer wall of the housing 1. A lead screw 51 is fixedly connected to the output end of the servo motor 50. The lead screw 51 passes through the housing 1 and is rotatably connected to the housing 1. A moving rod 52 is passed through the lead screw 51 and is threadedly connected to the lead screw 51. The moving rod 52 has an inner groove 521. A moving plate 522 is slidably connected to the inner wall of the moving rod 52. The moving plate 522 is elastically connected to the inner wall of the moving rod 52 by a spring. A rod body 523 is fixedly connected to the outer wall of the moving plate 522. The rod body 523 passes through the moving rod 52 and is slidably connected to the moving rod 52. A scraper 55 is fixedly connected to the outer wall of one end of the horizontal plate 53, and a sliding rod 531 is fixedly connected to the outer wall of the other end of the horizontal plate 53. The sliding rod 531 passes through the moving rod 52 and is slidably connected to the inner wall of the moving rod 52. An elastic limiting block 532 is slidably connected to the end of the sliding rod 531. A protrusion 56 is fixedly connected to the end of the horizontal plate 53. A fixing rod 54 is fixedly connected to the outer wall of the horizontal plate 53. The fixing rod 54 passes through the moving rod 52 and is slidably connected to the moving rod 52. The fixing rod 54 is elastically connected to the outer wall of the moving rod 52 by a spring.

[0029] Furthermore, a fixing block 524 is fixedly connected to the outer wall of the movable plate 522, and a slot 525 is opened in the movable plate 522. An inclined block 12 is fixedly connected to the inner wall of the housing 1. There are two sets of inclined blocks 12, and the two sets of inclined blocks 12 are symmetrically distributed on both sides of the inner wall of the housing 1. A collection box 11 is provided below the inclined block 12, and the collection box 11 is slidably connected to the housing 1.

[0030] In this utility model, when the filter screen 4 needs cleaning, the servo motor 50 is first started. At this time, through the transmission of the lead screw 51, the scraper 55 slides on the outer wall of the filter screen 4. By sliding the scraper 55 on the outer wall of the filter screen 4, the dirt adhering to the outer wall of the filter screen 4 can be cleaned. Figure 2As shown, when the scraper 55 moves above the collection box 11 under the drive of the servo motor 50, the dirt on the outer wall of the filter screen 4 will enter the interior of the collection box 11 under the push of the scraper 55. Then, the protrusion 56 will contact the inclined block 12, and the inclined block 12 will squeeze the protrusion 56, causing the horizontal plate 53 to drive the scraper 55 to move upward. At the same time, the spring fixedly connected to the outer wall of the fixed rod 54 undergoes elastic deformation. When the horizontal plate 53 moves downward, the spring fixedly connected to the outer wall of the horizontal plate 53 will... The sliding rod 531 slides on the inner wall of the sliding rod 52. When the sliding rod 531 moves a certain distance, the moving plate 522 contacts the elastic limiting block 532 and squeezes the elastic limiting block 532, causing the elastic limiting block 532 to completely enter the interior of the moving plate 522. When the force of the moving plate 522 on the elastic limiting block 532 disappears, the elastic limiting block 532 will pop out under the action of the spring force, thereby limiting the scraper 55. Then, the servo motor 50 is controlled to drive... The scraper 55 moves towards the servo motor 50. When the scraper 55 reaches the end of the lead screw 51, the rod 523 contacts the inner wall of the housing 1. Simultaneously, the inner wall of the housing 1 presses against the rod 523, causing the moving plate 522 to move along the inner wall of the moving rod 52. When the moving plate 522 moves, the slot 525 overlaps with the elastic limiting block 532, releasing the limiting force of the elastic limiting block 532. At this point, the scraper 55, under the action of spring force and gravity, again contacts the filter screen 4. The outer walls overlap, and then the servo motor 50 controls the scraper 55 to clean the outer wall of the filter screen 4 again. Through the design of the inclined block 12, the moving plate 522 and the elastic limiting block 532, the scraper 55 can clean the filter screen 4 in one direction and multiple times, thereby improving the cleaning effect of the filter screen 4 and preventing the scraper 55 from pushing the dirt of the filter screen 4 to the other side when returning. When the filter screen 4 is cleaned, the collection box 11 is finally pulled out to clean the dirt inside.
