Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a manhole cover for reducing water accumulation on roads. Background Art

[0002] A municipal manhole cover is a cover installed in public places such as urban roads and squares to facilitate the maintenance of road facilities. It is mainly used to cover the drainage pipes, cables, ventilation ducts and other facilities below to protect their normal operation.

[0003] In order to solve the problem that existing manhole covers may cause urban flooding due to untimely drainage when the rainfall is too heavy, the patent with patent publication number: CN220827876U discloses a manhole cover for reducing water accumulation on municipal roads. By setting a water receiving tray and a blocking block, rainwater enters the manhole cover along the first water inlet hole and falls into the water receiving tray. As the rainwater in the water receiving tray increases, the blocking block in the second water inlet hole slides downward to make the second water inlet hole unobstructed. At this time, the rainwater passes through the manhole cover along the second water inlet hole and the first water inlet hole and is discharged into the sewer. This can speed up the drainage of the road surface and reduce water accumulation.

[0004] However, during the implementation of the above solution, rainwater flows directly into the water receiving tray from the first water inlet hole. The debris carried by the rainwater can easily cause the water receiving tray to be blocked, resulting in the water in the water receiving tray being unable to be discharged, thereby affecting the normal use of the manhole cover. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a manhole cover for reducing water accumulation on roads.

[0006] The technical solution is: a manhole cover for reducing water accumulation on roads, including a cover plate, an adjusting mechanism and a cleaning mechanism. A water inlet is opened at the center of the cover plate, and a plurality of drain outlets are opened at intervals on the cover plate. An adjusting mechanism for controlling the opening and closing of the drain outlets is arranged at the bottom of the cover plate. A cleaning mechanism is arranged on the adjusting mechanism, and the cleaning mechanism is used to clean up debris carried in rainwater entering the adjusting mechanism.

[0007] Furthermore, the adjusting mechanism includes an L-shaped fixing plate, a conical baffle, a sleeve, a sleeve rod, a reset spring, a water collecting pan, an L-shaped connecting rod, a mounting ring and a blocking block. Five L-shaped fixing plates are fixedly connected to the bottom of the cover plate at intervals, a conical baffle is fixedly connected between the lower parts of the five L-shaped fixing plates, four sleeves are fixedly connected to the bottom of the conical baffle at intervals, sleeve rods are slidably connected in the sleeves, reset springs are connected between the sleeve rods and adjacent sleeves, a water collecting pan is commonly connected between the bottoms of the four sleeve rods, a plurality of drainage holes are provided at the bottom of the water collecting pan, L-shaped connecting rods are slidably provided on the five L-shaped fixing plates, a mounting ring is fixedly connected to the tops of the five L-shaped connecting rods, the lower parts of the five L-shaped connecting rods are fixedly connected to the side walls of the water collecting pan, a plurality of blocking blocks are fixedly connected to the top of the mounting ring at intervals, and the blocking blocks can close the water outlet.

[0008] Furthermore, the cleaning mechanism includes a shell, a filter, an impeller, a fixed seat, a rotating shaft, a scraper and a bevel gear. The top of the conical baffle is fixedly connected to the shell, and openings are provided at the top and bottom of the shell. A filter is provided at the opening at the top of the shell. The impeller is rotatably connected to the lower side of the shell, and a fixed seat is fixedly connected to the outer wall of the shell. The fixed seat is rotatably connected to the fixed seat. The lower end of the rotating shaft and the end of the impeller are fixedly connected to the bevel gear, and the two bevel gears are meshed with each other. The scraper is fixedly connected to the upper end of the rotating shaft, and the bottom of the scraper is in contact with the upper surface of the filter.

[0009] Furthermore, it also includes a protrusion, and the connection between the mounting ring and the blocking block is provided with a protrusion.

[0010] Furthermore, it also includes a guide plate, and the guide plate is fixedly connected to the water receiving tray.

[0011] Furthermore, all components except the cover plate are made of stainless steel.

[0012] The beneficial effects are: 1. By setting up a filter and a scraper, the filter can block debris such as leaves and stones carried in the rainwater to prevent the water receiving tray from being blocked. Through the cooperation of the impeller, bevel gear and rotating shaft, when rainwater passes through the shell, it can drive the scraper to scrape off the debris accumulated on the surface of the filter, ensuring that the water flow can flow normally through the shell into the water receiving tray.

[0013] 2. By providing the protrusions, the welding area between the blocking block and the mounting ring can be increased, thereby improving the connection strength between the mounting ring and the blocking block.

[0014] 3. By setting the guide plate, the water in the water receiving tray can be better discharged from the drainage hole, preventing rainwater from accumulating in the water receiving tray and stinking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Embodiment: A manhole cover for reducing water accumulation on roads, such as Figure 1-Figure 5 As shown, it includes a cover plate 1, an adjusting mechanism and a cleaning mechanism. A water inlet 2 is opened at the center of the cover plate 1. A plurality of drain outlets 21 are opened at intervals on the cover plate 1. An adjusting mechanism for controlling the opening and closing of the drain outlets 21 is arranged at the bottom of the cover plate 1. A cleaning mechanism is arranged on the adjusting mechanism, and the cleaning mechanism is used to clean up debris carried in rainwater entering the adjusting mechanism.

[0023] like Figure 1-Figure 4As shown, the adjustment mechanism includes an L-shaped fixing plate 31, a conical baffle plate 32, a sleeve 33, a sleeve rod 34, a reset spring 35, a water receiving tray 36, an L-shaped connecting rod 37, a mounting ring 38 and a blocking block 39. Five L-shaped fixing plates 31 are welded and fixed at intervals at the bottom of the cover plate 1. Conical baffle plates 32 are welded and fixed between the lower parts of the five L-shaped fixing plates 31. Four sleeves 33 are welded and fixed at intervals at the bottom of the conical baffle plate 32. Sleeve rods 34 are slidably connected in each sleeve 33. The sleeve rods 34 and the adjacent sleeves are connected. A reset spring 35 is connected between 33, a water receiving tray 36 is welded and fixed between the bottoms of the four sleeve rods 34, a plurality of drainage holes are provided at the bottom of the water receiving tray 36, an L-shaped connecting rod 37 is slidably provided on the five L-shaped fixing plates 31, a mounting ring 38 is welded and fixed on the top of the five L-shaped connecting rods 37, the lower parts of the five L-shaped connecting rods 37 are welded and fixed to the side wall of the water receiving tray 36, a plurality of blocking blocks 39 are welded and fixed at intervals on the top of the mounting ring 38, and the blocking blocks 39 can close the water outlet 21.

[0024] like Figure 4 and Figure 5 As shown, the cleaning mechanism includes a shell 41, a filter 42, an impeller 43, a fixed seat 44, a rotating shaft 45, a scraper 46 and a bevel gear 47. The shell 41 is welded and fixed on the top of the conical baffle 32. The top and bottom of the shell 41 are provided with openings, and rainwater can flow into the water receiving tray 36 through the shell 41. A filter 42 is provided at the opening at the top of the shell 41. The lower side of the shell 41 is rotatably connected to the impeller 43. When rainwater flows through the shell 41, it can push the impeller 43 to rotate. A fixed seat 44 is welded and fixed on the outer wall of the shell 41. The fixed seat 44 is rotatably connected to the rotating shaft 45. The lower end of the rotating shaft 45 and the end of the impeller 43 are fixedly connected to the bevel gear 47, and the two bevel gears 47 are meshed with each other. The scraper 46 is fixedly connected to the upper end of the rotating shaft 45, and the bottom of the scraper 46 is in contact with the upper surface of the filter 42.

[0025] The specific implementation method is as follows: first, the cover plate 1 is placed at the wellhead of the municipal drainage well. During heavy rain, rainwater falls on the filter screen 42 through the water inlet 2, and finally falls into the water receiving tray 36 through the shell 41 from the filter screen 42. The filter screen 42 can block debris such as leaves and stones to prevent the leaves and stones from accumulating in the water receiving tray 36 and blocking the drainage holes opened on the water receiving tray 36. When water passes through the shell 41, it will push the impeller 43 to rotate, thereby driving the scraper 46 to rotate through the bevel gear 47 and the rotating shaft 45. The rotation of the scraper 46 scrapes the surface of the filter screen 42 to scrape off the debris accumulated on the surface of the filter screen 42, thereby ensuring that the water flow can pass through the filter screen 42 normally. When the amount of water flowing into the water receiving tray 36 from the shell 41 is much greater than that flowing from the When the drainage volume flows out from the drainage hole, a certain amount of water accumulates in the water collecting pan 36, so that the overall weight of the water collecting pan 36 gradually increases. Under the action of gravity, the water collecting pan 36 moves downward, and the reset spring 35 is gradually stretched. The water collecting pan 36 drives the blocking block 39 to move downward through the connecting rod and the mounting ring 38, thereby opening the downspout 21. Rainwater can be discharged into the sewer from the water inlet 2 and the downspout 21 through the manhole cover. In this way, the drainage speed of the road is accelerated and the accumulation of water on the road is effectively reduced. When the rain stops, the water in the water collecting pan 36 is discharged from the drainage hole, and the overall weight of the water collecting pan 36 is reduced. Under the reset action of the reset spring 35, the water collecting pan 36 resets upward, thereby driving the blocking block 39 to re-close the downspout 21 and reduce the discharge of gas in the sewer.

[0026] like Figure 3 As shown, it also includes a protrusion 5. The protrusion 5 is set at the connection between the mounting ring 38 and the blocking block 39. The setting of the protrusion 5 can increase the welding area between the mounting ring 38 and the blocking block 39, so that the connection between the mounting ring 38 and the blocking block 39 can be more stable.

[0027] like Figure 4 and Figure 5 As shown, a guide plate 6 is also included. The water receiving tray 36 is fixedly connected with the guide plate 6. The guide plate 6 is a conical block, which can guide the water in the middle of the water receiving tray 36 to the edge so that it can be discharged from the drainage hole to prevent rainwater from accumulating in the water receiving tray and becoming smelly.

[0028] All components except the cover plate 1 are made of lightweight stainless steel, which can reduce the overall weight of the manhole cover and make it easier to lift the manhole cover when inspecting it.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
