Description

Technical Field

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

[0002] Municipal engineering generally belongs to the country's infrastructure, which refers to various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation, lighting and other infrastructure construction in urban construction. It is an indispensable material basis for the survival and development of cities, and a basic condition for improving people's living standards and opening up to the outside world. The drainage shaft is a structure used for drainage in municipal engineering. The drainage shaft is a device for discharging municipal sewage into the drainage pipe, and the manhole cover is indispensable in the drainage shaft.

[0003] Among them, steel grating manhole covers are one of the traditional manhole covers for municipal engineering. However, when the steel grating manhole covers are in use, due to the grating shape of the manhole covers, objects dropped by pedestrians are easy to fall into the sewer through the grating mesh holes set in the manhole covers, and it is inconvenient for pedestrians to take out the dropped objects. In view of the above problem, a manhole cover for municipal engineering is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a manhole cover for municipal engineering to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A manhole cover for municipal engineering includes a bottom rectangular frame plate, a connecting seat is fixedly connected to the top of the bottom rectangular frame plate, a cover plate is arranged in the connecting seat, the cover plate is rotatably connected to the connecting seat, an upper rectangular frame plate, a lower rectangular frame plate and a net bag are arranged in the connecting seat, the edge of the net bag is located between the upper rectangular frame plate and the lower rectangular frame plate, and the upper rectangular frame plate and the lower rectangular frame plate clamp the net bag with bolts, the cover plate is located directly above the upper rectangular frame plate, and a pull rope is fixedly connected between the net bag and the cover plate.

[0007] As a further solution of the utility model: a lifting plate is symmetrically fixedly connected to the inner wall of the upper rectangular frame plate.

[0008] As a further solution of the utility model: the top of the bottom rectangular frame plate is fixedly connected to the limiting columns at the four corners in the connecting seat, and the upper rectangular frame plate and the lower rectangular frame plate are provided with connecting holes adapted to the limiting columns.

[0009] As a further solution of the utility model: a plurality of reinforcing plates are fixedly connected between the outer wall of the connecting seat and the top of the bottom rectangular frame plate.

[0010] As a further solution of the utility model: an operating hole is opened through the cover plate, a connecting shaft is rotatably connected to the bottom of the cover plate on one side of the operating hole, a clamping plate is fixedly connected to the connecting shaft, a dial plate is fixedly connected to both sides of the clamping plate, a through hole is arranged on the dial plate, and a clamping groove adapted to the clamping plate is opened on the inner wall of the connecting seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model arranges a net bag in a connecting seat, and the net bag is fixed by an upper rectangular frame plate and a lower rectangular frame plate. The net bag filters the passing water to reduce the amount of garbage such as plastic bags and leaves that enter the sewer. At the same time, the net bag catches things dropped by pedestrians to prevent the things from falling into the sewer. A drawstring connected to the net bag is pulled through the grid-shaped strip holes preset on the cover plate, so that the net bag moves upward, making it convenient for people who drop things to take them out.

[0013] The utility model connects the cover plate by operating a wrench through an operating hole and a through hole formed on the dial plate. The operating wrench dials the dial plate to rotate the connecting shaft, and the connecting shaft rotates with the clamping plate, so that the clamping plate is built into the clamping groove, thereby limiting the position of the cover plate and reducing the probability of accidental opening of the cover plate during use.
