Implementation

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] See also Figure 1-2 In this embodiment, a rainwater inlet filtering device for municipal engineering includes a filter box 1, a support assembly 2 is arranged on the top of the filter box 1, and the support assembly 2 is used to fix the whole. A first filter screen 3 is fixed inside the filter box 1, and the first filter screen 3 is arranged to filter impurities, so as to store the impurities inside the filter box 1 to prevent the blockage of the sewer. A pushing plate 4 is slidably connected to the inner cavity of the filter box 1, and the pushing plate 4 is arranged to push the impurities to move. A scraper 5 is fixed on the top of the pushing plate 4, and the scraper 5 is arranged to clean the first filter screen 3. The pushing plate 4 and the scraper 5 are both tightly fitted with the first filter screen 3, and the tight fit makes the overall operation more stable.

[0022] In addition, a handle 10 is fixed to the top of the second filter screen 8, and the handle 10 is provided so that the second filter screen 8 can be conveniently pulled to move. A reset assembly is fixed to the top of the pushing plate 4, and the reset assembly includes a connecting rod 6, a coupling rod 7 and a reset spring 9. The connecting rod 6 is fixed to the top of the pushing plate 4, and the outer surface of the connecting rod 6 is slidably connected to the coupling rod 7. Sliding blocks are fixed on the left and right sides of the coupling rod 7. A sliding groove slidably connected to the sliding block is provided inside the connecting rod 6. The sliding connection between the sliding block and the sliding groove makes the movement of the connecting rod 6 more stable, and makes it difficult for the connecting rod 6 and the coupling rod 7 to separate. The coupling rod 7 is fixed to the second filter screen 8, and the connecting rod 6 and the pushing plate 4 are fixed with the reset spring 9. When the pushing plate 4 is subjected to greater pressure, the connecting rod 6 will move downward, and when the pressure is reduced, the reset spring 9 will pull the connecting rod 6 to reset.

[0023] Furthermore, the reset assembly is used to pull the push plate 4 to move, and a second filter screen 8 slidingly connected to the filter box 1 is fixed on the top of the reset assembly. A limiting groove is provided on the top of the filter box 1, and the second filter screen 8 is slidingly connected to the limiting groove. The limiting groove is used to limit the upward movement of the second filter screen 8, and a threaded hole connected to the limiting groove is provided on the top of the support plate 201.

[0024] In general, the push plate 4 can prevent impurities from falling to the bottom of the filter box 1, and the scraper 5 can clean the first filter 3, and when the first filter 3 is blocked, rainwater will accumulate on the top of the push plate 4. When the pressure of the push plate 4 increases, the connecting rod 6 will move downward, thereby exposing more area of ​​the first filter 3, and when the rainwater decreases, the reset spring 9 will pull the scraper 5 to reset, thereby cleaning the first filter 3, so that the whole can be used for a longer time, effectively improving the overall practicality.

[0025] See also Figure 3In order to facilitate cleaning of the whole, the support assembly 2 in this embodiment includes a support plate 201, a third filter screen 202, a support rod 203, a fixing plate 204 and a control rod 205. The bottom of the support plate 201 is fixed to the filter box 1, and mounting blocks are fixed on both sides of the support plate 201. The inside of the mounting block is slidably connected with expansion nails, and the expansion nails are used to fix the whole. The third filter screen 202 is slidably connected to the support plate 201, and the bottom of the third filter screen 202 is fixed to two support rods 203. The support rods 203 are used to fix the third filter screen 202. The second filter screen 8 is supported, thereby effectively limiting the movement of the second filter screen 8. The top of the support plate 201 is threadedly connected to the fixed plate 204. The outer surface of the fixed plate 204 is fixed with a threaded strip threadedly connected to the threaded hole. The fixed plate 204 and the scraper 5 are both hollow rings on the inside. The fixed plate 204 is used to squeeze the third filter screen 202, thereby completing the fixation of the third filter screen 202. The top of the fixed plate 204 is plugged into the control rod 205, and is configured to be plug-in so that the control rod 205 can be removed after use.

[0026] In general, by rotating the fixing plate 204, the fixing plate 204 can be moved downward due to the extrusion of the thread, thereby squeezing the third filter screen 202, and the third filter screen 202 will squeeze the second filter screen 8 through the support rod 203, thereby completing the fixation of the whole, and facilitating subsequent disassembly and cleaning, making the whole more practical.

[0027] The working principle of the above embodiment is:

[0028] When the filter box 1 needs to be cleaned, the fixing plate 204 can be rotated by rotating the control rod 205, so that the fixing plate 204 will move away from the inside of the support plate 201 under the squeezing of the thread, so that the third filter screen 202 loses its fixation, and the third filter screen 202 can be easily taken out. After taking out the third filter screen 202, the handle 10 can be pulled to make the connecting rod 7 and the connecting rod 6 pull the push plate 4 to move upward. During the movement, the scraper 5 will scrape the impurities to the top of the push plate 4, and then drive them away from the inside of the filter box 1 together. The overall structure is simple, which makes the whole easy to clean, making the whole more practical.
