[0025] See also Figure 1-Figure 5As shown, the utility model is a drainage manhole cover for municipal engineering, comprising a manhole seat 1, a manhole cover body 2 and a linkage assembly 3. The manhole cover body 2 is arranged at the top of the manhole seat 1 and is snap-connected thereto. Main drainage outlets 201 are provided on both sides of the upper surface of the manhole cover body 2. A hinged seat 203 is fixedly connected to the middle of the bottom surface of the manhole cover body 2. A connecting plate 204 is hingedly connected to the inside of the hinged seat 203. Both ends of the connecting plate 204 are fixedly connected to an insertion rod 205. The insertion rod 205 is arranged at the main drainage outlet 201. A number of secondary drainage outlets 202 are evenly provided on the upper surface of the manhole cover body 2. The linkage assembly 3 comprises a slider 301 and a connecting rod 307. The connecting rod 307 is arranged inside the hinged seat 203 and rotatably cooperates therewith. The connecting rod 307 is vertical to the connecting plate 204, and a matching rod 308 is sleeved on the circumference of the connecting rod 307.
[0026] The connecting rod 307 and the matching rod 308 are fixedly connected to hinge plates 309 on both sides of the peripheral surface. The hinge plate 309 is fixedly connected to the surface of multiple groups of plug blocks 306. The plug blocks 306 are plugged into and matched with the auxiliary drain outlet 202. A sliding groove is provided on the inner wall of one side of the well seat 1. One end of the slider 301 is set in the sliding groove and slides with it. A card slot is provided on both sides of the surface of the other end of the slider 301. One end of the connecting rod 307 is fixedly connected to a connecting pin head 310, which is engaged with one group of card slots. One end of the matching rod 308 is fixedly connected to a matching pin head 311, which is engaged with the other group of card slots.
[0027] The bottom end of the slider 301 is fixedly connected to a connecting rod 302, which is arranged on the outside of the slide groove. The connecting rod 302 is "L"-shaped, and both sides of the bottom surface of the manhole cover body 2 are fixedly connected with sliding rods 303. A linkage plate 304 is slidably connected between the two groups of sliding rods 303. The linkage plate 304 is arranged below the connecting plate 204, and one end of the connecting rod 302 is fixedly connected to the linkage plate 304.
[0028] Both sides of the bottom surface of the linkage plate 304 are fixedly connected with matching springs 305 . The matching springs 305 are sleeved on the peripheral side of the slide bar 303 , and one end of the matching spring 305 is fixedly connected to the bottom end of the slide bar 303 .
[0029] The size of the main drain port 201 is larger than that of the insertion rod 205 , and the spring 305 is made of plastic.
[0030] During normal drainage, water flows through the main drain outlet 201 for drainage, and the water flow impacts the connecting plate 204. Under the action of the lever principle, one end of the connecting plate 204 moves down and the other end moves up, thereby causing the plug rod 205 to swing back and forth at the main drain outlet 201, preventing the main drain outlet 201 from being blocked by debris and affecting drainage; during the drainage process, due to the large water flow, it enters through the main drain outlet 201 and impacts the linkage plate 304. The linkage plate 304 is forced to press down the matching spring 305, and the matching spring 305 is deformed, causing the linkage plate 304 to drive the connecting rod 302 to move downward, thereby causing the slider 301 to move, and driving the connecting pin head 310 and the matching The movement of the coupling pin head 311 causes the connecting rod 307 and the matching rod 308 to rotate, which in turn drives the hinge plate 309 to swing, causing the insert block 306 to move out from the auxiliary drain outlet 202, thereby accelerating the drainage speed of the manhole cover body 2 and improving the drainage efficiency; after the water flow becomes smaller, the linkage plate 304, under the action of the matching spring 305, drives the connecting rod 302 to move upward, and then drives the slider 301 to move upward, and drives the connecting rod 307 and the matching rod 308 to rotate through the connecting pin head 310 and the matching pin head 311, so that the hinge plate 309 returns to its position, and the insert block 306 is inserted into the auxiliary drain outlet 202 to push out the debris inside, thereby avoiding affecting the next drainage.
[0031] It should be noted that the distance that the slider 301 moves in the slide groove can only drive the connecting pin head 310 and the matching pin head 311 to rotate the connecting rod 307 and the matching rod 308, and will not drive the connecting rod 307 and the matching rod 308 to move downward.
