[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] See also Figure 1-6 A rainwater discharge device based on an urban integrated pipe gallery comprises a pipe gallery body 1, a sewer pipe body 2 is embedded and installed on the pipe gallery body 1, a manhole cover body 3 is installed between the sewer pipe body 2 and the pipe gallery body 1, a plurality of drainage holes 6 are drilled on the manhole cover body 3, a filter screen plate 8 is in close contact with the inside of the sewer pipe body 2, and an elastic telescopic mechanism 7 is installed between the manhole cover body 3 and the filter screen plate 8, a supporting clamp 10 is fixedly connected to the inner wall of the sewer pipe body 2, and an embedded fixing ring 9 in close contact with the supporting clamp 10 is provided on the supporting clamp 10, an elastic auxiliary mechanism 11 is installed between the embedded fixing ring 9 and the filter screen plate 8, a filter box 4 is fixedly connected to the lower end of the sewer pipe body 2, and the filter box 4 is installed on the inner bottom end of the pipe gallery body 1, and a drainage filter pipe 5 is fixedly connected to the outer end of the filter box 4.

[0032] During use of the present invention, rainwater enters the sewer pipe body 2 through the multiple drainage holes 6 and falls on the filter screen plate 8 for preliminary filtration, blocking the large debris such as leaves therein for filtration. During this process, when a vehicle is driving or a pedestrian is walking, the vehicle contacts the pressure plate 703 in the elastic telescopic mechanism 7 and squeezes it to move downward, driving the movable rod 702 to move upward with the assistance of a pair of sliding rods 704, and stretching the superimposed elastic telescopic ring 705, prompting the movable rod 702 to drive the filter screen plate 8 to move downward. The filter screen plate 8 moves downward, squeezing the multiple moving rods 1103 in the elastic auxiliary mechanism 11 to move toward the inside of the built-in straight cylinder 1101, causing the piston 1102 to move downward and stretching the spring 1104. After the vehicle or pedestrian separates from the pressure plate 703, the squeezing disappears. At this time, the filter screen plate 8 is moved upward between the spring 1104 and the superimposed elastic telescopic ring 705. The movable rod 702 and the pressing plate 703 are moved upward under the common elastic action, driving the movable rod 702 and the pressing plate 703 to reset upward. When the pressing plate 703 is squeezed by a vehicle or pedestrian next time, it moves downward again, and repeats this process. The debris accumulated on the filter screen plate 8 moves with the frequent up and down movements, and the position becomes loose and dispersed, and it is not easy to gather together, thereby reducing the accumulation of debris and avoiding clogging of the filter screen plate 8, thereby ensuring the discharge efficiency of rainwater in the sewer pipe body 2. Then the rainwater discharged from the sewer pipe body 2 falls into the filter box 4 for secondary filtration and is discharged through the drainage filter pipe 5, so as to facilitate the subsequent collection and utilization of the filtered rainwater. Moreover, the embedded fixing ring 9 and the supporting clamp ring 10 are connected in a detachable embedded snap-fit ​​manner, so that when the manhole cover body 3 is subsequently disassembled, the manhole cover body 3 is lifted to move upward, which can drive the filter screen plate 8 to move upward, so as to facilitate the cleaning of the debris thereon.

[0033] See also Figure 1-5 The elastic telescopic mechanism 7 includes a cylinder 701 embedded in the manhole cover body 3, a movable rod 702 is provided inside the cylinder 701, and circular holes are drilled at the inner top and bottom ends of the cylinder 701, and the upper and lower ends of the movable rod 702 pass through the circular holes and extend to the outside thereof, the upper end of the movable rod 702 is fixedly connected to a pressing plate 703, and the lower end of the movable rod 702 is fixedly connected to the filter screen plate 8, and the outer end of the movable rod 702 is fixedly connected to a pair of sliding rods 704, and the outer end of the movable rod 702 is sleeved with a superimposed elastic telescopic ring 705, and the upper and lower ends of the superimposed elastic telescopic ring 705 are respectively fixedly connected to the upper end of the sliding rod 704 and the inner top of the cylinder 701.

[0034] When the vehicle or pedestrian is separated from the pressure plate 703, the pressure plate 703 is pressed downward by the elastic expansion mechanism 7, and the movable rod 702 is driven to move upward with the assistance of a pair of sliding rods 704, and the superimposed elastic expansion ring 705 is stretched, so that the movable rod 702 drives the filter screen plate 8 to move downward. After the vehicle or pedestrian separates from the pressure plate 703, the squeezing disappears. At this time, the filter screen plate 8 is reset upward under the elastic reset action of the superimposed elastic expansion ring 705, driving the movable rod 702 and the pressure plate 703 to reset upward. When the pressure plate 703 is squeezed by the vehicle or pedestrian next time, it moves downward again. This is repeated, so that the debris accumulated on the filter screen plate 8 moves with the frequent up and down movements, the position becomes loose, and it is dispersed, and it is not easy to gather together, thereby reducing the accumulation of debris, avoiding clogging of the filter screen plate 8, and ensuring the discharge efficiency of rainwater in the sewer pipe body 2.

[0035] See also Figure 4-5 A pair of slide grooves 7041 are cut on the inner wall of the cylinder 701, and the ends of the pair of sliding rods 704 that are away from each other are respectively located in the pair of slide grooves 7041 and are slidably connected thereto.

[0036] During use of the present invention, the slide groove 7041 is provided so that the pair of sliding rods 704 can move up and down along the slide groove 7041 to maintain stable movement, thereby achieving stable assistance for the movement of the movable rod 702 .

[0037] See also Figure 1-2 The surface of the pressing plate 703 is provided with a wear-resistant layer.

[0038] During use of this solution, by providing a wear-resistant layer, the pressing plate 703 is not easily worn out during long-term pressing, thereby extending its service life.

[0039] See also Figure 2 , Figure 4 and Figure 6 The elastic auxiliary mechanism 11 includes a plurality of built-in straight cylinders 1101 fixedly connected to the upper end of the embedded fixing ring 9, a piston 1102 is slidably connected inside the plurality of built-in straight cylinders 1101, and a moving rod 1103 is fixedly connected to the upper end of the piston 1102, through holes are drilled in the inner top ends of the plurality of built-in straight cylinders 1101, and the upper ends of the plurality of moving rods 1103 pass through the through holes and are fixedly connected to the lower end of the filter screen plate 8, and the outer ends of the plurality of moving rods 1103 are sleeved with springs 1104, and the upper and lower ends of the spring 1104 are fixedly connected to the inner top ends of the built-in straight cylinders 1101 and the upper end of the piston 1102, respectively.

[0040] During use of the present solution, the filter screen plate 8 moves downward, squeezing the multiple moving rods 1103 to move toward the inside of the built-in straight cylinder 1101, causing the piston 1102 to move downward and stretching the spring 1104. After the squeezing disappears, the elastic reset action of the spring 1104 can drive the moving rods 1103 to push the filter screen plate 8 to reset upward, thereby achieving the auxiliary enhancement of the elastic reset action by the spring 1104 while the superimposed elastic telescopic ring 705 is acting, so that the filter screen plate 8 can quickly reset upward.

[0041] See also Figure 4-6 The inner walls of the plurality of through holes and the pair of circular holes are fixedly connected with sealing rings 12, and the inner walls of the plurality of sealing rings 12 are in close contact with the outer ends of the moving rod 1103 and the movable rod 702, respectively.

[0042] During use of the present invention, the sealing ring 12 is provided to seal the gap between the movable rod 702 and the circular hole and the gap between the movable rod 1103 and the through hole, thereby reducing the penetration of rainwater.
