[0025] The filter body 1 and the drum frame 2 are both made of stainless steel, which can improve the corrosion resistance of the device and increase the overall service life of the device. The surface of the filter body 1 is fixedly connected with a water spray pipe 9 that penetrates the surface of the filter body 1. The water spray pipe 9 is located directly above the drum frame 2 to flush impurities on the inner wall of the drum frame 2.

[0026] The inner wall of the end cover 3 is fixedly connected with an internal gear ring 10, the inner wall of the collecting bucket 5 is rotatably connected with a bidirectional lead screw 6, the surface of the bidirectional lead screw 6 is fixedly connected with a gear 13, the surface of the gear 13 is meshed with the surface of the inner gear ring 10, and the rotation of the end cover 3 can be transmitted to the bidirectional lead screw 6, thereby ensuring the smooth operation of the device.

[0027] Furthermore, a screw nut 12 is threadedly connected to the surface of the bidirectional screw 6, a moving block 11 is slidably connected to the inner wall of the collecting bucket 5, the surface of the screw nut 12 is slidably connected to the inside of the moving block 11, and a second spring 19 is fixedly connected between the screw nut 12 and the moving block 11, and then the position of the moving block 11 is restored by the setting of the second spring 19.

[0028] Both sides of the inner wall of the collecting bucket 5 are provided with moving grooves 18, which are composed of two horizontal grooves, a vertical groove and an inclined groove, and the depth of the inclined groove gradually becomes shallower from top to bottom, the depth of the upper end of the inclined groove is the same as the depth of the upper horizontal groove, and the depth of the lower end of the inclined groove is shallower than the depth of the lower horizontal groove. Both sides of the moving block 11 are fixedly connected with fixed sleeves 14, and the surfaces of the two fixed sleeves 14 slide with the inner walls of the two moving grooves 18 respectively. The inner wall of the fixed sleeve 14 is slidably connected with a sliding rod 16, and the surface of the sliding rod 16 also slides with the inner wall of the moving groove 18. The surface of the sliding rod 16 is fixedly connected with a first spring 15, and the end of the first spring 15 away from the sliding rod 16 is fixedly connected to the inner wall of the fixed sleeve 14 for resetting the sliding rod 16.

[0029] A conical scraper 17 is fixedly connected to the bottom of the moving block 11 to scrape impurities from the inner wall of the collecting bucket 5. When the scraper 17 contacts the inner bottom wall of the collecting bucket 5, the slide rod 16 and the fixed sleeve 14 slide in the horizontal groove below the moving groove 18, and the second spring 19 is in a stretched state at this time.

[0030] Furthermore, a discharge pipe 7 connected to the inside of the collecting bucket 5 is fixedly connected to the surface of the collecting bucket 5 to discharge impurities.

[0031] Specifically, when in use, the rotation of the end cover 3 drives the internal gear ring 10 to rotate, and the meshing of the internal gear ring 10 and the gear 13 drives the bidirectional lead screw 6 to rotate, thereby driving the lead screw nut 12 and the moving block 11 to slide in the collecting bucket 5, and driving the fixed sleeve 14 and the slide bar 16 to slide in the lower horizontal groove of the moving groove 18. At the same time, the movement of the moving block 11 drives the scraper 17 to push the impurities on the inner wall of the collecting bucket 5, and push the impurities to the impurity discharge pipe 7, so that the impurities are discharged through the impurity discharge pipe 7, and at this time, the fixed sleeve 14 and the slide bar 16 move to the horizontal groove of the moving groove 18. , and then at this time, under the elastic force of the second spring 19, the moving block 11 is driven to slide and rise in the collecting bucket 5, so that the scraper 17 no longer contacts the inner wall of the collecting bucket 5, and the scraper 17 will not push the impurities when returning, and then with the continued rotation of the two-way lead screw 6, the lead screw nut 12 and the moving block 11 return, and then drive the fixed sleeve 14 and the slide bar 16 to slide in the horizontal groove on the moving groove 18, and with the continued rotation of the two-way lead screw 6, the fixed sleeve 14 and the slide bar 16 move in the inclined groove of the moving groove 18, so that the inner wall of the inclined groove of the moving groove 18 pushes the slide bar 16 The sliding rod 16 is pushed to gradually retract into the fixed sleeve 14 and compress the first spring 15. Then, as the bidirectional lead screw 6 continues to rotate, the fixed sleeve 14 and the sliding rod 16 enter the lower horizontal groove of the movable groove 18. Then, the fixed sleeve 14 obtains the moving space again. At this time, under the elastic force of the first spring 15, the sliding rod 16 slides out of the fixed sleeve 14. At this time, since the depth of the lower end of the inclined groove of the movable groove 18 is shallower than the depth of the lower horizontal groove of the movable groove 18, there is a certain step between the lower end of the inclined groove of the movable groove 18 and the lower horizontal groove of the movable groove 18, so that the sliding rod 16 is blocked. Therefore, when the fixed sleeve 14 and the slide rod 16 slide in the horizontal groove under the movable groove 18, they will not slide along the inclined groove of the movable groove 18, thereby ensuring the smooth operation of the device. Then, as the bidirectional screw 6 continues to rotate, the scraper 17 continues to push the impurities in the inner wall of the collecting bucket 5, and then during the implementation of the device, the impurities in the collecting bucket 5 can be continuously pushed to accelerate the discharge of impurities, thereby avoiding impurities from being retained in the device for a long time, causing impurities to continuously fall into the water body, thereby reducing the filtering efficiency of the device on water quality, thereby improving the use effect of the device, and it is worthy of promotion.

[0032] Working principle: The rotation of the end cover 3 drives the internal gear ring 10 to rotate, and at the same time, the meshing of the internal gear ring 10 and the gear 13 drives the bidirectional lead screw 6 to rotate, thereby driving the lead screw nut 12 and the moving block 11 to slide in the collecting bucket 5, and driving the fixed sleeve 14 and the slide rod 16 to slide in the lower horizontal groove of the moving groove 18. At the same time, the movement of the moving block 11 drives the scraper 17 to push the impurities on the inner wall of the collecting bucket 5, and push the impurities to the impurity discharge pipe 7, so that the impurities are discharged through the impurity discharge pipe 7.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
