[0045] When it is necessary to clean the sundries collected inside the filtering component 24, first take out the cover plate 215, and then start the stepper motor 2308, so that the rotating shaft 2306 drives the conical gear three 2307 to rotate, and then drives the conical gear two 2301 on the right to rotate. The rotation of the conical gear two 2301 on the right drives the conical gear one 238 and the connecting shaft 235 on the right to rotate. The rotation of the connecting shaft 235 on the right drives the connecting rod 236 to rotate on the inner wall of the support sleeve 237, so that the connecting shaft 235 and the conical gear one 238 on the left rotate and drive the conical gear two 2301 on the left to rotate. The rotation of the conical gear two 2301 drives the rotating rod 2302 to rotate on the inner wall of the circular moving hole two, and then drives the threaded rod 2303 to rotate. The rotation of the threaded rod 2303 drives the slider 2304 to move on the outer wall of the threaded rod 2303, and then drives the connecting block two 2305 to lift the rectangular through hole 226. The lifting of the rectangular through hole 226 drives the connecting block one 225 to make the sliding sleeve 224 slide on the outer wall of the sliding rod 223, improving the stability of the movement of the rectangular through hole 226. At the same time, the movement of the rectangular through hole 226 drives the baffle 228, the connecting plate 229, and the ejector rod 2201 to lift. First, the connecting plate 229 slides on the inner wall of the rectangular jack 217, and the second shunt through hole 220 above the connecting plate 229 will move out of the upper part of the installation groove body two 221, then the lower second shunt through hole 220 will be aligned with the upper first shunt through hole 216 and the third shunt through hole 32. The upper part of the outer wall of the baffle 228 will block the lower first shunt through hole 216 and the third shunt through hole 32. At this time, the ejector rod 2201 will insert into the filtering component 24. With the start of the stepper motor 2308, the baffle 228 will block the first shunt through hole 216 and the third shunt through hole 32, preventing the impurities that have not entered the separation structure from flowing, and at the same time will drive the filtering component 24 to lift, facilitating the lifting of the sundries collected by the filtering component 24 and removing them from the inside of the installation component 21.

[0046] As Figure 9As shown in the figure, the filtering component 24 includes two concave plates 241. The outer wall of the concave plate 241 is movably connected to the inner wall of the first installation groove body 211.

The outer wall of the limit block 243 is movably connected to the inner wall of the limit groove 213. A stable insertion slot 244 is provided at the bottom of the limit block 243. The inner wall of the stable insertion slot 244 is movably connected to the top of the ejector rod 2201. The bottom of the concave plate 241 is fixedly connected with a bottom plate 245. Dovetail grooves 246 are provided on both the left and right sides of the front side of the bottom plate 245. T-shaped sliding plates 247 are fixedly connected to both the left and right sides of the top of the lower concave plate 241. The outer wall of the T-shaped sliding plate 247 is movably connected to the inner wall of the dovetail groove 246. A filter screen 248 is fixedly connected to the rear side of the inner wall of the concave plate 241;

[0047] The sundries flowing through the third shunt through-hole 32 into the concave plate 241 are intercepted by the filter screen 248. After the ejector rod 2201 is inserted into the stable insertion slot 244 and drives the filtering component 24 to be lifted, the lifting groove 242 will be pulled to move the filtering component 24 to the ground. Then, by pushing the upper or lower concave plate 241, the T-shaped sliding plate 247 moves on the inner wall of the dovetail groove 246 and disengages from the inner wall of the dovetail groove 246, thereby disassembling the two concave plates 241, which is convenient for cleaning the sundries collected in the concave plate 241.

[0048] In addition, the present invention also relates to a usage method of a rainwater and sewage diversion reconstruction structure for an urban municipal drainage system, including the following steps:

[0049] Step 1: Prepare the construction site, ensure the safety of the construction area, and set up necessary warning signs and fences to prevent irrelevant personnel from entering the construction area.

[0050] Step 2: According to the design drawings, position and excavate the drainage trough 1 to ensure that the size and position of the drainage trough are accurate.

[0051] Step 3: Open the first installation groove 12, connection groove 13, motor groove 14, fixed groove 15, and second installation groove 16 on the inner wall of the water trough body 11 in the drainage trough 1, and connect the fixed grooves 15 on the left and right sides of the bottom of the inner wall of the water trough body 11 with the second installation groove 16 and the first installation groove 12.

[0059] The working principle of the present invention:

[0060] When it is necessary to clean the sundries collected inside the filtering component 24, first remove the cover plate 215, and then start the stepper motor 2308, so that the rotating shaft 2306 drives the conical gear 2307 to rotate, and then drives the conical gear 2301 on the right to rotate. The rotation of the conical gear 2301 on the right drives the conical gear 238 and the connecting shaft 235 on the right to rotate. The rotation of the connecting shaft 235 on the right drives the connecting rod 236 to rotate on the inner wall of the support sleeve 237, so that the connecting shaft 235 and the conical gear 238 on the left rotate and drive the conical gear 2301 on the left to rotate. The rotation of the conical gear 2301 drives the rotating rod 2302 to rotate on the inner wall of the circular moving hole 2, and then drives the threaded rod 2303 to rotate. The rotation of the threaded rod 2303 drives the slider 2304 to move on the outer wall of the threaded rod 2303, and then drives the connecting block 2305 to lift the rectangular through hole 226. The lifting of the rectangular through hole 226 drives the connecting block 225 to make the sliding sleeve 224 slide on the outer wall of the sliding rod 223, improving the stability of the movement of the rectangular through hole 226. At the same time, the movement of the rectangular through hole 226 drives the baffle 228, the connecting plate 229, and the ejector rod 2201 to lift. First, the connecting plate 229 slides on the inner wall of the rectangular jack 217, and the shunt through hole 220 above the connecting plate 229 will move out of the upper part of the mounting groove body 221, so that the lower shunt through hole 220 will be aligned with the upper shunt through hole 216 and the shunt through hole 32. The upper outer wall of the baffle 228 will block the lower shunt through hole 216 and the shunt through hole 32. At this time, the ejector rod 2201 will be inserted into the filtering component 24. With the start of the stepper motor 2308, the baffle 228 will block the shunt through hole 216 and the shunt through hole 32, preventing impurities that have not entered the separation structure from flowing, and at the same time will drive the filtering component 24 to lift, facilitating the lifting of the sundries collected by the filtering component 24 and removing them from the inside of the mounting component 21.

[0061] The sundries flowing from the shunt through hole 32 to the inside of the concave plate 241 are intercepted by the filter net 248. After the ejector rod 2201 is inserted into the inside of the stable slot 244 and drives the filtering component 24 to lift, the lifting groove 242 will be pulled to move the filtering component 24 to the ground. Then, push the upper or lower concave plate 241 to make the T-shaped slide plate 247 move on the inner wall of the dovetail groove 246 and disengage from the inner wall of the dovetail groove 246, thereby disassembling the two concave plates 241 and facilitating the cleaning of the sundries collected inside the concave plate 241.
