Workers do not need to manually lift the manhole cover to speed up drainage, which reduces the labor intensity of workers.
[0022] 3. By setting a guide rod and a guide shell that cooperate with the water inlet ring and the water inlet trough, it can ensure that the water inlet ring can fall back onto the inner ring stably and accurately during the automatic lifting of the water inlet ring and the water inlet trough, thereby realizing the accurate reset of the water inlet ring.

[0042] like Figures 1 to 10 The present invention provides a municipal drainage manhole cover, comprising an outer ring 1, an installation mechanism 2 is provided on the outer side of the outer ring 1, an inner support mechanism 3 is provided inside the outer ring 1, a lifting mechanism 4 is provided on the upper side of the inner support mechanism 3, a cross output mechanism 5 is provided directly below the lifting mechanism 4, and a position adjustment mechanism 6 is provided directly below the cross output mechanism 5. The lifting mechanism 4 comprises a top cover 41, an axle seat 42 is fixedly installed at the center of the bottom of the top cover 41, a linkage rod 43 is fixedly installed at the bottom of the axle seat 42, an upper cross bar 44 is fixedly installed at the lower end of the linkage rod 43, a water inlet ring 45 is fixedly installed on the side of the bottom of the top cover 41 away from the linkage rod 43, a water inlet groove 46 is provided inside the water inlet ring 45, a circular groove 47 is provided inside the top cover 41, the water inlet grooves 46 are evenly distributed on the water inlet ring 45 in a circular shape, and the number of the water inlet grooves 46 is several.
[0043] In this embodiment, the top cover 41, the linkage rod 43 and the upper cross bar 44 are connected into a whole through the shaft seat 42. In extreme weather, the upper cross bar 44 and the linkage rod 43 move upward, pushing the top cover 41 and the water inlet ring 45 to rise synchronously, so that the water inlet groove 46 on the water inlet ring 45 is exposed to the outside of the outer ring 1. The accumulated water on the road surface will then enter the interior of the well from the water inlet groove 46, draining the accumulated water on the municipal road surface, effectively improving the drainage efficiency of the municipal road surface.
[0044] Example 2

[0046] In this embodiment, the installation of the manhole cover can be quickly achieved by combining the installation ring 21 with the manhole cover installation groove opened in advance. When the amount of rainwater is small, it will flow into the interior of the well from the trapezoidal hole 22 to drain the road surface. The reinforcement block 23 and the reinforcement ring 24 are located on the outside of the outer ring 1 to support and reinforce the entire outer ring 1, which can effectively improve the pressure resistance of the entire manhole cover, thereby effectively enhancing the stability of the manhole cover.
[0047] Example 3
[0048] like Figures 1 to 10As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the inner support mechanism 3 includes an inner ring 31 fixedly mounted on the inner wall of the outer ring 1, and a well 32 is fixedly mounted on the bottom of the inner ring 31. A positioning hole 33 is also provided inside the well 32, and a guide rod 34 is fixedly mounted on the top of the inner ring 31. The outer side of the guide rod 34 is slidably connected to a guide shell 35, and the guide shell 35 is fixedly mounted on the bottom of the top cover 41. The cross output mechanism 5 includes upper sliders 51 fixedly mounted on the left and right ends of the upper cross bar 44. The number of upper sliders 51 is two, one upper slider 51 is slidably connected to the left oblique rod 52, and the other upper slider 51 is slidably connected to the right oblique rod 53. The upper sliders 51 are located at the upper ends of the left oblique rod 52 and the right oblique rod 53, and the two upper sliders 51 are on the same horizontal line. A rectangular groove 55 is provided inside the left oblique rod 52, and a rotating rod 54 is fixedly mounted on the outer side of the right oblique rod 53. The right oblique rod 53 passes through the rectangular groove 55 in a cross shape. The inclined rod 53 is rotatably connected, the rotating rod 54 passes through the wellbore 32 and is located in the positioning hole 33, the rotating rod 54 is rotatably connected to the positioning hole 33, the lower ends of the left inclined rod 52 and the right inclined rod 53 are slidably connected with the lower slider 56, the number of the lower slider 56 is two, and the two lower sliders 56 are on the same horizontal line, the position adjustment mechanism 6 includes a lower cross bar 61 fixedly mounted on the outside of the lower slider 56, the bottom of the lower cross bar 61 is fixedly mounted with a connecting rod 62, and the lower end of the connecting rod 62 is fixedly mounted There is a connecting block 63, and a water cylinder 64 is fixedly installed on the inner side of the connecting block 63. First overflow holes 65 are opened around the inner wall of the water cylinder 64, and a seepage bottom plate 66 is fixedly installed on the bottom of the water cylinder 64. A second overflow hole 67 is opened inside the seepage bottom plate 66. The number of the first overflow holes 65 and the second overflow holes 67 is several. The first overflow holes 65 are evenly distributed in a circular shape outside the water cylinder 64, and the second overflow holes 67 are evenly distributed in a cross shape on the seepage bottom plate 66.
[0049] In this embodiment, by arranging the water collecting cylinder 64 just below the top cover 41, rainwater can enter the water collecting cylinder 64. When the amount of water in the water collecting cylinder 64 is greater than two-thirds of the volume of the water collecting cylinder 64, the gravity of the water collecting cylinder 64 + the rainwater in the water collecting cylinder 64 > the gravity of the cross output mechanism 5 + the gravity of the lifting mechanism. In addition, the diameters of the first overflow hole 65 and the second overflow hole 67 are smaller than the diameters of the circular groove 47. When there is less rainwater, the water in the water collecting cylinder 64 cannot accumulate. The water inflow speed in the water collecting cylinder 64 is lower than the water outflow speed. At the same time, rainwater will be discharged from the first overflow hole 65 and the second overflow hole 67. When there is a lot of rain in extreme weather, water inside the water cylinder 64 will accumulate. The water inflow speed in the water cylinder 64 is much faster than the water outflow speed. The rainwater cannot be discharged from the first overflow hole 65 and the second overflow hole 67 in time. When the rainwater inside the water cylinder 64 accumulates to two-thirds, with the positioning hole 33 as the rotation point, under the action of gravity, the water cylinder 64 drives the lower cross bar 61 to move downward, so that the inner angle between the left oblique bar 52 and the right oblique bar 53 becomes smaller, thereby prompting the upper cross bar 44 to move upward, driving the lifting mechanism 4 to move upward.
[0050] In specific use, the present invention is used as a municipal drainage manhole cover. When encountering extreme weather, the rainwater will surge, and the rainwater on the road will enter the well from the trapezoidal hole 22 and the circular groove 47. The water part that passes through the circular groove 47 will enter the water cylinder 64 below. At this time, due to the surge of rainwater, the water inlet speed in the water cylinder 64 is much faster than the water outlet speed, and the rainwater will gradually accumulate in the water cylinder 64. When the amount of rainwater in the water cylinder 64 is greater than two-thirds of its volume, the water cylinder 64 + the rainwater inside the water cylinder 64 will accumulate. The gravity of water> the gravity of the cross output mechanism 5+ the gravity of the lifting mechanism. Under the action of the rotating rod 54 and the wellbore 32, with the positioning hole 33 as the rotation fixed point, under the action of gravity, the inner angle between the left oblique rod 52 and the right oblique rod 53 becomes smaller, and the water container 64 drives the lower slider 56 to slide obliquely downward. During the downward movement of the lower slider 56, the lower cross bar 61 is synchronously moved downward. At the same time, the upper slider 51 will move obliquely upward in this process. During the upward movement of the upper slider 51, the upper cross bar 44 is synchronously moved upward. The upward movement of the upper cross bar 44 will push The linkage rod 43 moves upward, and the linkage rod 43 pushes the top cover 41 and the water inlet ring 45 to move upward synchronously. At the same time, the guide rod 34 and the guide shell 35 assist the top cover 41 to move upward stably, so that the water inlet groove 46 on the water inlet ring 45 is exposed to the outside of the outer ring 1, and the drainage mechanism of the manhole cover - the water inlet groove 46 is automatically added. The drainage mechanism is composed of the water inlet groove 46, the trapezoidal hole 22 and the circular groove 47. Due to the addition of the drainage mechanism (water inlet groove 46, the trapezoidal hole 22 and the circular groove 47), the drainage of the water accumulated on the road surface will be accelerated. The walking speed is increased, thereby effectively improving the drainage efficiency of the municipal road surface. After the accumulated water on the road surface is drained, the water inflow speed in the water storage cylinder 64 is lower than the water outflow speed. While the water is flowing in, the rainwater will be discharged from the first overflow hole 65 and the second overflow hole 67. The water inside the water storage cylinder 64 cannot accumulate, resulting in the gravity of the water storage cylinder 64 + the rainwater inside the water storage cylinder 64 being less than the gravity of the cross output mechanism 5 + the gravity of the lifting mechanism. The top cover 41 will accurately return to the inner cavity of the outer ring 1 with the assistance of the guide rod 34 and the guide shell 35, and realize automatic recovery.
[0051] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
