KR20110006765A - A functional manhole - Google Patents

Abstract

The present invention is additionally attached to the manhole cover to block the openings of the manholes in everyday life, which helps to create a pleasant urban environment by blocking various gases and odors generated from sewage pipes and rising up the roads or sidewalks. By reducing the inflow of sewer, etc., it reduces the use of cleaning and semi-equipment, and contributes to suppressing the occurrence of various pests.The opening is opened only when rain or backflow occurs in the sewer pipe, and drains rainwater to the sewer pipe. Or a device designed to enable a smooth flow of water by discharging over a sidewalk.

Description

Functional manhole {A FUNCTIONAL MANHOLE}

The present invention performs the function of blocking the inflow of garbage or fallen leaves into the sewage pipe in the manhole installed on the road or the bad smell and harmful gas generated in the sewage pipe, and the rotation of the wing only when rain or rain occurs in rainy weather It is a device designed to prevent human accidents caused by loss or loss of manhole cover by draining the drain by sewage pipe and discharging it by opening the wing when a backflow occurs in the sewage pipe.

Conventional devices have a risk of human accidents due to the loss of manhole cover due to backflow, and major components are made of metal, which can cause rust after prolonged periods of time. It has a structure that can generate a lot of cost, and it lacks economic feasibility because it has a problem of exchanging the whole manhole to exhibit the same function.

This design has a wire mesh for minimizing waste flowing into sewage pipes, and the plastic material is used for the main driving part so that rust does not occur even when used for a long time, and it is additionally installed in the existing manhole cover without replacing the whole manhole or changing the structure. It is possible to minimize the cost required by the opening and closing operation of the attached wing to block odor or harmful gas at normal times, and to block the inflow of waste into sewage pipes. It is a device designed to prevent the occurrence of human accidents due to the loss or loss of manholes by discharging rainwater to sewage pipes by opening the wings and discharging backflow from sewage pipes to the roads by opening the wings.

This device is provided with (2) mounting frame for fixing to the bottom of sewage pipe or manhole, (2) attaching each component to the mounting frame, (3) with wing fixing plate and It is equipped with (4) wing to control the flow of water and backflow, (5) mobile stopper to control the operating range of the wing, and (6) wire mesh to minimize the waste flowing into the sewage pipe.

By installing this device, it prevents the inflow of garbage and fallen leaves into sewage pipes, reduces the use of quasi-facilities for cleaning, suppresses the occurrence of diseases and pests, and blocks harmful gases and odors generated from sewage pipes. It also contributes to the improvement, and the odor can be covered by covering manholes with plywood or plywood, which can prevent much of the damage caused by the inflow of rainwater caused by undesired flooding or other drainage.

The device is equipped with a [FIG. 1] mounting frame, [FIG. 2] wing fixing plate, [FIG. 3] wing, [FIG. 4] movable stopper, [FIG. 5] wire mesh, and as shown in FIG. Is closed so that garbage or foreign substances on the road do not flow into the sewage pipe, and harmful gases or odors generated from the sewage pipe are not allowed to come up on the road. As a result, the wing is opened downward by the load of the running water so that the running water on the road is drained to the sewage pipe, and after the running water is discharged, the wing is closed again, and when the backflow occurs in the sewer pipe, As shown in [8], the wing is opened upward by the reverse flow, and the reverse flow is discharged on the road to prevent the loss of manhole cover or human accidents due to the loss. It is supposed to be.

Fig. 1 shows each component such as a mounting frame, Fig. 2 wing fixing plate, Fig. 3 blade, Fig. 4 movable stopper, and Fig. 5 wire mesh. FIG. 7 illustrates the operation of the blade and the movable stopper when the water flow occurs, and FIG. 8 illustrates the flow of the reverse flow.

Claims (1)

It is installed in the manhole cover and is normally closed to block harmful gases or odors, and to open and move up and down in the event of flowing water or backflow, it has a wing [Fig. 3] to discharge water, as shown in [Fig. 4]. Device with movable stopper to control vane movement
