Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-2 As shown, a water conservancy project sewage cleaning grid comprises a rectangular frame 1, and the inner side wall of the rectangular frame 1 is rotatably connected with a plurality of grid plates 2 for intercepting garbage;

[0025] The top of the rectangular frame 1 is symmetrically provided with slide grooves 3, and the rectangular frame 1 is also fixedly connected with a cleaning component for self-cleaning garbage and a storage component for storing garbage in cooperation with the cleaning component.

[0026] The cleaning assembly includes a support frame 8, which is fixedly connected to the top of the rectangular frame 1 symmetrically and located behind the slide slot 3. The bottom of the support frame 8 is fixedly connected to a second spring 14, and the top of the second spring 14 is fixedly connected to a sleeve rod 9, which is slidably connected to the support frame 8.

[0027] The top of the sleeve rod 9 is fixedly connected with a pressure plate 10, the inner end of the sleeve rod 9 is fixedly connected with a rotating shaft 11, the rotating shaft 11 is rotatably connected with a sliding rod 12, and the bottom of the sliding rod 12 is slidably connected to the sliding groove 3;

[0028] The lower ends of the opposite surfaces of the symmetrical sliding rods 12 are fixedly connected with scrapers 13 .

[0029] The storage assembly includes four rod bodies 6, which are inserted into the rectangular frame 1. The inner ends of the rod bodies 6 pass through the side walls of the rectangular frame 1 and enter the slide groove 3. The first spring 5 is fixedly connected to the slide groove 3. The first spring 5 is sleeved on the outside of the rod body 6 and the other end of the first spring 5 is fixedly connected to the circular plate at the inner end of the rod body 6.

[0030] The storage assembly also includes two dirt storage frames 4, which are symmetrically fixedly connected to both sides of the rectangular frame 1;

[0031] The outer ends of the rod bodies 6 adjacent to each other on the left and right are fixedly connected with sealing plates 7 , and the sealing plates 7 are slidably connected to the top opening of the dirt storage frame 4 .

[0032] The bottom of the sealing plate 7 is made of flexible plastic and fits exactly on the top of the grid plate 2 .

[0033] Working principle:

[0034] In actual use, the grille is horizontally fixed and connected to the inlet of the drainage system. The water volume at the inlet of the urban drainage system is closely related to the activity time of urban residents. Based on this, the drainage system in the west of the city is divided into two states: large flow and small flow.

[0035] When the pressure plate 10 is impacted by a large flow of water, the pressure plate 10 transmits pressure downward to the sleeve rod 9, the second spring 14 is compressed, and the sleeve rod 9 moves downward, thereby driving the slide bar 12 to move toward the end of the chute 3 away from the support frame 8. At this time, the scraper 13 passes over the top of the grid plate 2 to scrape away the intercepted garbage;

[0036] When the slide bar 12 moves to the edge of the slide slot 3, it touches and squeezes the rod body 6, thereby compressing the first spring 5, and then the rod body 6 moves to the outside of the rectangular frame 1, and the sealing plate 7 moves away from the top opening of the dirt storage frame 4, and the garbage intercepted by the scraper 13 is cleaned and stored in the dirt storage frame 4;

[0037] When the large flow of water is converted into a small flow of water, the second spring 14 rebounds upward, the sleeve rod 9 moves upward, and the slide bar 12 moves in the direction close to the support frame 8 inside the slide groove 3. At this time, the scraper 13 passes over the top of the grid plate 2 again to scrape away the intercepted garbage;

[0038] When the slide bar 12 moves in the opposite direction in the slide groove 3, the first spring 5 rebounds, the rod body 6 slides toward the inside of the rectangular frame 1, and the sealing plate 7 returns to the top opening of the dirt storage frame 4 to cover all the garbage;

[0039] Repeat the above process until the dirt storage frame 4 is full, and wait for the cleaning staff to clean the garbage in the dirt storage frame 4, which is convenient for the cleaning staff and also facilitates the filtering efficiency of the grille;

[0040] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
