Description

Technical Field

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

[0002] Traditional road manhole covers in the field of municipal road facilities technology include: cast iron manhole covers, concrete manhole covers, waste plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are widely used because of their high strength and long life. The installation of manhole covers is mostly done by installing the top cover on the corresponding base. In this way, when encountering heavy rain, the top cover is easily washed away by excessive water flow, resulting in the exposure of the wellhead and causing danger. Some manhole covers are hinged to the base to achieve relative fixation of the top cover and the base. However, due to the influence of vehicle traffic, the top cover is easily damaged by the long-term pressure of the vehicle on the top cover, or when the top cover is broken and damaged, the top cover needs to be removed, and the hinged connection between the top cover and the base makes it inconvenient to disassemble and replace the top cover, affecting work efficiency.

[0027] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] Embodiment 1

[0029] In a typical implementation of the present invention, reference is made to Figure 1 As shown, a municipal road manhole cover includes a base and a top cover 1. The inner side of the base 2 is provided with an annular chute and a plurality of vertical chute grooves. The bottom of the vertical chute is connected to the annular chute and the top extends to the top surface of the base. A spring assembly is vertically arranged on the inner side of the base on the side of the vertical chute. A lifting groove 3 is arranged at the center of the top cover, and a slider 8 is arranged at the bottom edge. The slider 8 is arranged corresponding to the vertical chute 5. The slider 8 enters the annular chute 6 through the vertical chute 5 to compress the spring assembly 7. The top cover is rotated to a set angle to lock the top cover. This embodiment can realize the locking of the top cover after quick installation, and can be quickly disassembled when the top cover needs to be replaced.

[0030] like Figure 2 and Figure 3 As shown, the base 2 is in a circular ring shape, and an annular slide groove and two vertical slide grooves 5 are arranged on its inner wall. The bottom of the vertical slide groove is connected to the annular slide groove 6, and the top extends to the top surface of the base.

[0031] like Figure 1-Figure 2 As shown, the top cover 1 is circular, and a number of seepage holes 4 are evenly distributed on the top cover to facilitate water seepage. A water collecting box 9 is arranged at the bottom of the top cover corresponding to the position of the seepage holes, and the bottom of the water collecting box is connected to the drain pipe. The water collecting box is a boxed structure, and the purpose is to drain water to the drain pipe 10. The drain pipe is U-shaped, and the inner wall of the drain pipe is bonded with activated carbon particles to absorb the unpleasant gas.

[0032] In a preferred example, the outer wall of the water collecting box 9 fits with the inner side of the base 2, which is conducive to the water collecting box 9 to drain the rainwater that penetrates into the gap between the top cover 1 and the base 2.

[0033] like Figure 2 and Figure 3 As shown, the slider 8 is an L-shaped slider, and the L-shaped sliders are evenly distributed on the edge of the top cover. In this embodiment, there are two vertical slide grooves, so two sliders 8 are set, and two groups of spring assemblies are correspondingly set.

[0034] The push-spring assembly 7 and the vertical slide groove are staggered on the inner side of the base to ensure that the push-spring assembly will not interfere with the rotation angle of the top cover. The push-spring assembly includes a through-core column 71, a top column 72 and a reset spring 73. The through-core column is vertically welded to the inner side of the base, the top end of the reset spring 73 is fixedly connected to the top column, and the bottom end extends to the inside of the through-core column. The through-core column is a cylindrical structure with an open top; in the natural state, the height of the top column is not lower than the top surface of the base. When the reset spring is compressed, the top column can enter the channel of the through-core column and slide with the through-core column.

[0035] like Figure 1 As shown, a lifting groove 3 is provided at the center of the top cover, and the shape of the lifting groove 3 is a cross. The setting of the lifting groove 3 facilitates workers to manually rotate the top cover 1 and provides a force application point.

[0036] One end of the L-shaped slider is connected to the bottom edge of the top cover 1, and the other end is parallel to the top cover and extends outward by a set distance. The worker grasps the lifting groove part, lowers the top cover 1, and aligns the L-shaped slider with the vertical slide groove. At this time, the top cover can be lowered, and the bottom of the top cover 1 presses down the top column. The reset spring 73 begins to be compressed and continues to press down until the slider moves down along the vertical slide groove to the annular slide groove. At this time, the top cover is rotated, the slider is staggered with the vertical slide groove, and the top of the slider is abutted through the annular slide groove. At this time, the top cover is not easy to fall out. And under the action of the reset spring, the top cover is subjected to the force of upward movement, which further locks the top cover. When encountering heavy rain in the rainy season, the top cover will not be separated from the base due to excessive water flow.

[0037] When the damaged top cover 1 needs to be replaced, the top cover 1 is rotated in the reverse direction through the lifting groove so that the slider 8 overlaps with the vertical slide groove 5. Then, under the action of the return spring 73 in the push-spring assembly, the top cover is lifted up, which can realize quick disassembly and replacement of the top cover, and the operation is simple.

[0038] This embodiment can not only prevent the top cover 1 from being washed away by water flow, thereby exposing the wellhead and causing danger, but also facilitate operators to replace and repair the damaged top cover, thereby improving applicability.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
