Technical Field

[0001] The utility model relates to the field of municipal manhole covers, in particular to a manhole cover for municipal road drainage. Background Art

[0002] On city streets, drainage manhole covers play an important role in dredging rainwater on the streets. Especially in my country's summer, there is a lot of rain and heavy rainfall. If the precipitation on the streets is not removed in time, it will have an adverse impact on the city's traffic.

[0003] However, traditional municipal road drainage manhole covers still have certain shortcomings: first, in some cases, the surface of the manhole cover is damaged or the manhole cover is detached from the manhole, and it is difficult for pedestrians and vehicles nearby to observe this phenomenon, and it is easy for them to step into the manhole, causing losses and physical injuries; second, when certain extreme weather conditions lead to continuous heavy rains, the drainage port on the surface of the manhole cover cannot bear a large flow, but the manhole cover cannot be directly opened completely. Therefore, some manhole covers are provided with a function to adjust the drainage flow of the manhole cover, but the structure is complex and inconvenient for nearby residents to operate, and the components are prone to damage due to long-term contact with water.

[0004] Therefore, it is necessary to provide a new municipal road drainage manhole cover to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a manhole cover for municipal road drainage which has a durable structure and is convenient for adjusting the drainage volume of the manhole cover and can give a warning when the manhole cover falls off.

[0006] In order to solve the above technical problems, the utility model provides a manhole cover for municipal road drainage, comprising: a manhole cover, a plurality of drainage holes evenly distributed around an axis are opened on the surface of the manhole cover, a vertical pipe is arranged inside the drainage hole, the top and the bottom of the vertical pipe are both arranged as an opening structure, a plurality of drainage ports are opened on the side wall surface of the vertical pipe, a vertical bar is fixedly connected to the side wall surface of the vertical pipe, a groove is opened on the side wall of the drainage hole, the vertical bar is slidably connected to the groove, a block is welded on the side wall surface of the vertical pipe located at the lower side of the vertical bar, the size of the block is larger than the size of the groove, and the block located at the lower side of the manhole cover is welded to the side wall surface of the vertical pipe. A base is provided at a position, the base is rotatably connected to the manhole cover, the bottom of the base is fixedly connected to an inner tube, the side wall surface of the inner tube is vertically provided with a plurality of sliding grooves evenly distributed around the axis, the inside of the sliding groove is slidably connected to a slider, an oblique support is welded to the top of the slider, a storage cylinder is fixedly connected between the plurality of oblique supports, a compression spring is fixedly connected to the bottom inner wall of the storage cylinder, a support plate is provided on the top of the compression spring, an outer rod is vertically provided at the top center of the support plate, the inside of the outer rod is connected to an inner rod through a spring, and a plurality of warning plates are installed on the top of the inner rod.

[0008] Through the above technical solution, under normal circumstances, the manhole cover is covered on the base, and the top of the storage cylinder is located inside the limit cover, which can prevent external sewage from entering the storage cylinder. When the manhole cover is damaged or lost, the outer rod inside the storage cylinder is pushed out of the manhole by the reaction force of the compression spring, and the inner rod is also connected to the outer rod by a spring, so it will drive the warning plate to rise. Pedestrians and vehicles on the road can see the erected warning sign, thereby preventing the danger of stepping on air. In other cases, pedestrians have poor attention and do not notice the warning plate, but since multiple groups of inclined supports are provided to fix the storage cylinder, pedestrians can be prevented from falling directly into the manhole, and the structure can protect the safety of personnel.

[0009] As a further solution of the utility model, a mounting plate is welded to the outer wall surface of the base, and a plurality of mounting holes evenly distributed around the axis are opened on the surface of the mounting plate.

[0010] Through the above technical solution, the device is fixed in the road through the mounting plate, and when installing the manhole cover, it should be ensured that the surface of the manhole cover is flush with the ground to prevent the unevenness from affecting the driving of vehicles.

[0011] As a further solution of the utility model, a sign is connected to the center of the upper surface of the manhole cover by bolts, and a through groove is opened on the surface of one side wall of the manhole cover.

[0012] Through the above technical solution, relevant units can put corresponding logos on the surface of the signboard, and then use bolts to fix it on the manhole cover. The through groove on one side of the manhole cover is used to insert the crowbar. After the manhole cover has been used for a long time, it needs to be pried open with a crowbar.

[0013] As a further solution of the utility model, a limiting block is welded on the side wall surface of the support plate, and a limiting groove is provided on the inner wall surface of the storage cylinder, and the limiting groove is slidably connected to the limiting block.

[0016] Through the above technical solution, in some cases, workers may have to go down to the manhole to work. At this time, the warning structure can be removed from the inside of the inner tube by unscrewing the fastening bolts.

[0017] As a further solution of the utility model, a lifting rod is fixedly connected inside each of the vertical tubes.

[0018] Through the above technical solution, when it rains, the manhole cover is blocked or the water flow is too large, and the surrounding residents or pedestrians do not have tools such as crowbars to pry open the manhole cover, the vertical pipe can be pulled upward by the lifting rod. The multiple sets of drainage ports arranged on the surface of the vertical pipe can increase the drainage capacity of the manhole cover, and effectively avoid sucking in surrounding garbage to cause blockage. When the user lifts the vertical pipe, it should be rotated at a certain angle to move the vertical bar to one side of the groove to prevent the vertical pipe from falling naturally due to gravity.

A manhole cover for municipal road drainage includes:

[0030] A manhole cover 1, a surface of the manhole cover 1 is provided with a plurality of drainage holes 8 evenly distributed around the axis, a vertical pipe 3 is arranged inside the drainage hole 8, the top and bottom of the vertical pipe 3 are both arranged as an opening structure, a side wall surface of the vertical pipe 3 is provided with a plurality of drainage ports 28, a vertical bar 26 is fixedly connected to the side wall surface of the vertical pipe 3, a groove 9 is provided on the side wall of the drainage hole 8, the vertical bar 26 is slidably connected to the groove 9, a stopper 27 is welded on the side wall surface of the vertical pipe 3 located below the vertical bar 26, the size of the stopper 27 is larger than the size of the groove 9, a base 2 is arranged at the position below the manhole cover 1, and the base 2 is rotatably connected to the manhole cover 1 The bottom of the base 2 is fixedly connected with an inner tube 5, and the side wall surface of the inner tube 5 is vertically opened with a plurality of slide grooves 11 evenly distributed around the axis, and the inside of the slide groove 11 is slidably connected with a slider 15, and an inclined support 12 is welded to the top of the slider 15, and a storage cylinder 13 is fixedly connected between the plurality of inclined supports 12, and a compression spring 18 is fixedly connected to the bottom inner wall of the storage cylinder 13, and a support plate 19 is arranged on the top of the compression spring 18, and an outer rod 20 is vertically arranged at the top center position of the support plate 19, and the inside of the outer rod 20 is connected with an inner rod 21 through a spring, and a plurality of warning plates 23 are installed on the top of the inner rod 21.

[0031] like Figure 1 As shown, a slot 24 is formed on the surface of the outer rod 20 , the warning plate 23 is located inside the slot 24 , the bottom surface of the manhole cover 1 is fixedly connected to the limit cover 10 , and the top of the storage cylinder 13 is located inside the limit cover 10 .

[0032] Under normal circumstances, the manhole cover 1 is covered on the base 2, and the top of the storage cylinder 13 is located inside the limit cover 10, which can prevent external sewage from entering the storage cylinder 13. When the manhole cover 1 is damaged or lost, the outer rod 20 inside the storage cylinder 13 is pushed out of the manhole by the reaction force of the compression spring 18, and the inner rod 21 is also connected to the outer rod 20 by a spring, so it will drive the warning plate 23 to rise. Pedestrians and vehicles on the road can see the erected warning sign, thereby preventing the danger of stepping on air. In other cases, pedestrians have poor attention and do not notice the warning plate 23, but since multiple groups of inclined supports 12 are provided for fixing the storage cylinder 13, pedestrians can be prevented from falling directly into the manhole, and the structure can protect the safety of personnel.

[0033] like Figure 1 As shown, a mounting plate 6 is welded to the outer wall surface of the base 2, and a plurality of mounting holes 7 evenly distributed around the axis are opened on the surface of the mounting plate 6.

[0034] The device is fixed in the road through the mounting plate 6, and when installing the manhole cover 1, it should be ensured that the surface of the manhole cover 1 is flush with the ground to prevent the unevenness therefrom from affecting the driving of vehicles.

[0035] like Figure 1As shown, a sign 4 is connected to the center of the upper surface of the manhole cover 1 by bolts, and a through groove 22 is opened on the surface of one side wall of the manhole cover 1.

[0036] The relevant units can put corresponding logos on the surface of the sign 4, and then fix it on the manhole cover 1 with bolts. The through slot 22 on one side of the manhole cover 1 is used to insert a crowbar. After the manhole cover 1 has been used for a long time, a crowbar is needed to pry it open.

[0042] When it rains, the manhole cover 1 is blocked or the water flow is too large, and the surrounding residents or pedestrians do not have tools such as crowbars to pry open the manhole cover 1. At this time, the vertical pipe 3 can be pulled upward by the lifting rod 29. The multiple groups of drainage ports 28 arranged on the surface of the vertical pipe 3 can increase the drainage volume of the manhole cover 1 and effectively avoid clogging caused by sucking in surrounding garbage. When the user lifts the vertical pipe 3, it should be rotated at a certain angle to move the vertical bar 26 to one side of the groove 9 to prevent the vertical pipe 3 from naturally falling down due to gravity.

[0043] The working principle of a manhole cover for municipal road drainage provided by the utility model is as follows:

[0044] Step 1: Under normal circumstances, the manhole cover 1 is covered on the base 2, and the top of the storage cylinder 13 is located inside the limit cover 10, which can prevent external sewage from entering the storage cylinder 13. When the manhole cover 1 is damaged or lost, the outer rod 20 inside the storage cylinder 13 is pushed out of the manhole by the reaction force of the compression spring 18, and the inner rod 21 is also connected to the outer rod 20 by a spring, so it will drive the warning plate 23 to rise, and pedestrians and vehicles on the road can see the erected warning sign, so as to prevent the danger of stepping on the air. In other cases, pedestrians have poor attention and do not notice the warning plate 23, but because the inclined support 12 for fixing the storage cylinder 13 is provided with multiple groups, it can prevent pedestrians from falling directly into the manhole, and the structure can protect the safety of personnel;

[0045] The second step: when it rains, the manhole cover 1 is blocked or the water flow is too large, and the surrounding residents or pedestrians do not have tools such as crowbars to pry open the manhole cover 1. At this time, the vertical pipe 3 can be pulled upward by the lifting rod 29. The multiple groups of drainage ports 28 arranged on the surface of the vertical pipe 3 can increase the drainage volume of the manhole cover 1 and effectively avoid clogging caused by sucking in surrounding garbage. When the user lifts the vertical pipe 3, it should be rotated at a certain angle to move the vertical bar 26 to one side of the groove 9 to prevent the vertical pipe 3 from naturally falling down due to gravity.
