Description

Technical Field

[0001] This utility model relates to the field of manhole covers, and in particular to a manhole cover with safety protection function. Background Technology

[0002] Urban construction involves the design of numerous pipelines, including drainage pipes and cable conduits, along with corresponding drainage outlets and inspection ports, necessitating the installation of manhole covers for concealment. These covers are often removed from manholes for maintenance, emergency drainage, or theft. If the city's drainage network is poorly designed or during heavy rains, drainage difficulties can lead to water accumulation. Current solutions typically involve removing the manhole cover completely, exposing the manhole. This exposure poses a safety hazard, prompting the installation of fall protection nets. However, this still cannot prevent pedestrians or vehicles from falling into the manhole. Therefore, a manhole cover with safety protection features is urgently needed to address these issues.

[0026] Reference Figures 1 to 3 A manhole cover with safety protection function includes a mounting base 10, a cover body 20, a limiting component 30 and an elastic component 40;

[0027] The mounting base 10 is provided with a first drain outlet 11 that runs vertically through the base. The inner side wall of the mounting base 10 is provided with a number of mounting grooves 12 and a number of drain grooves 13 in a circumferential direction.

[0028] The outer side wall of the cover 20 is provided with a plurality of support plates 21 extending into the mounting groove 12. The cover 20 can move vertically relative to the mounting base 10 so that the cover 20 has a closed position and a drainage position.

[0029] The limiting component 30 is connected between the mounting base 10 and the cover 20 to keep the cover 20 in a closed position or a drainage position;

[0030] The elastic component 40 is disposed between the support plate 21 and the bottom surface of the mounting groove 12 to provide an upward thrust to the cover 20;

[0031] The drainage channel 13 may be connected only to the first drainage outlet 11 when the cover 20 is in the closed position, or the drainage channel 13 may be connected to the space above the cover 20 and the first drainage outlet 11 when the cover 20 is in the drainage position.

[0032] In this utility model, during assembly, the elastic component 40 is first installed in the mounting groove 12. In some possible embodiments, the elastic component 40 includes several springs 41, one end of which abuts against the support plate 21 and the other end of which abuts against the bottom surface of the mounting groove 12. In a further embodiment, the bottom surface of the mounting groove 12 is provided with a limiting groove, and the spring 41 is disposed in the limiting groove, which can limit the separation of the spring 41 from the mounting base 10. After the limiting component 30 is installed on the cover 20, the cover 20 is installed on the mounting base 10. Specifically, the support plate 21 on the cover 20 presses against the upper end of the spring 41.

[0033] Reference Figures 1-3In some embodiments, the limiting component 30 includes a plurality of limiting pins 31. The inner sidewall of the mounting base 10 is provided with first pin holes 32 and second pin holes 33 arranged at intervals in the vertical direction. The limiting pins 31 are movably mounted on the cover 20. The cover 20 can be kept in a closed position when the limiting pins 31 are inserted into the first pin holes 32, or the cover 20 can be kept in a drainage position when the limiting pins 31 are inserted into the second pin holes 33. In use, if the weather is normal and there is no large amount of water accumulation on the road surface, the cover 20 is operated to move upward, so that the limiting pins 31 are arranged opposite to the first pin holes 32, and the limiting pins 31 are pushed in. The cover 20 is kept in the closed position by moving the cover into the first pin hole 32. At this time, the drainage channel 13 is only connected to the first drainage outlet 11. When heavy rain causes water to accumulate on the road, the cover 20 is moved downward until the limiting pin 31 is positioned opposite the second pin hole 33. The limiting pin 31 is then pushed into the second pin hole 33, keeping the cover 20 in the drainage position. At this time, the drainage channel 13 is connected to the space above the cover 20 and the first drainage outlet 11, allowing the water on the road to enter the drainage channel 13 from the top of the cover 20 and then flow into the manhole through the first drainage outlet 11.

[0034] Reference Figures 1-3 In some embodiments, the limiting components 30 are set in three groups and arranged at intervals along the circumference of the cover 20, which can improve the limiting effect and also make the cover 20 have good balance when it is on the manhole cover 20 of pedestrians or vehicles, thus avoiding shaking.

[0035] Reference Figures 1-3 In some embodiments, a manhole cover with safety protection function also includes several cover plates 60 connected to the mounting base 10 via a detachable structure 50 to form a closed mounting groove 12; as a preferred embodiment of the detachable structure 50, the detachable structure 50 is configured as a bolt connection structure; the cover plate 60 is used to restrict the separation of the cover body 20 from the mounting base 10.

[0036] Reference Figures 1-3 In some embodiments, the cover 20 is provided with a second drain outlet 22 that runs vertically through the top and bottom, and the second drain outlet 22 can meet the daily drainage function under normal conditions.

[0037] The advantages of this utility model are: the above structure allows the cover to be switched to the drainage position when water accumulates, so that the water can flow into the well through the drainage channel and the first drainage outlet, improving drainage efficiency. At the same time, it does not require the cover to be removed, thus improving safety.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
