(Technology)

The present invention relates to a sewage cover, and more specifically, to reduce the sewage cleaning cost by preventing the sewage inflow and sewage of sewage, and improves aesthetics and hygiene by blocking the ground backflow of sewage or odor and pests It is related with the sewer cover which can be done.

(Background)

Roads, etc., are equipped with sewerage for draining sewage, such as rainwater, or sewage, and flowing water along the ground is collected through sewage wells provided at regular intervals in the sewer. It is common to cover a cover, such as a grating, that can filter out dirt to prevent entry. It is also common to cover open sewers exposed to the ground without landfilling to prevent dirt from entering.

Covers for sewerage vary widely depending on the installation location and environment of the sewerage, for example, metal gratings formed by welding steel in a lattice shape, covers made by molding concrete, and the like.

However, in the conventional conventional sewage cover, various sewage that has flowed down with the running water is cluttered on the lattice, which causes aesthetics and causes odors and pests. There was a problem that cleaning is very cumbersome.

As an alternative to solve the problems of the conventional sewer cover, a sewer cover has been developed that is equipped with a valve closed and opened by the gravity of the heavy weight and the flow of running water.

Such a conventional valve type cover is based on a structure in which a long rod is inserted into a hole drilled on both sides thereof, and the rotating shaft is mounted on the rotating shaft, and the valve is rotatably mounted on the rotating shaft. Is implied.

First, in inserting and installing a rotating shaft (rod) into a hole drilled in the side, the centers of the opposite rotating shafts are not positioned in a straight line and are often misaligned or difficult to mount the valve. In the manufacturing process of the cover, it is very cumbersome to align the axis center of the rotation shaft in a straight line.

Second, the opening angle of the valve is difficult to exceed about 70 degrees, because of this, when a large amount of flowing water flows, the presence of the valve can act as a resistance to prevent drainage.

Third, since the opening angle of the valve does not exceed 70 degrees, when the external force is applied to the valve, the valve is easily bent by the external force and out of its proper angle.In this case, the valve is opened without closing even in normal times when the water does not flow. In some cases, the original function of preventing the inflow of dirt and odor can be prevented.

Fourth, when dirt is placed on the valve, the valve may be opened due to its load, and when such foreign matter is caught in the gap of the valve, the valve may not be closed.

An object of the present invention is to solve the problems of the conventional sewage cover as described above, to reduce the sewage cleaning costs by more completely blocking the sewage inflow and sewage of the sewage, and also to reduce the sewage and odor and pests It is to provide a sewer cover that can improve the aesthetics and hygiene by preventing ground backflow.

According to the invention there is provided a sewer cover.

The sewer cover according to the present invention includes a cover body, pivot supports and on / off valves.

The cover body includes a top plate, frames for supporting the top plate, drain holes formed in the top plate, and mounting holes formed in pairs on both sides adjacent to the respective drain holes.

The pivot support includes a head caught by the mounting hole, a support shaft extended from the head, and a rotation shaft formed on the support shaft, and inserted into the mounting hole such that the rotation shaft faces each of the drain holes. Is mounted.

The opening and closing valve, the opening and closing plate for opening and closing the drain hole, the support plate bent at an angle with respect to the opening and closing plate, a bearing formed in the support plate is inserted into the rotation shaft rotatably, and the opposite position of the opening and closing plate It includes a weight fixed to the support plate.

Preferably, the opening and closing plate is formed with a convex convex upward, preferably the weight is wrapped around the end of the support plate and fixed.

Preferably, the rotation shaft is spaced apart from the top plate so that the weight can be rotated to a position higher than the height of the rotation shaft.

Hereinafter, with reference to the accompanying drawings will be described in detail the sewer cover according to the present invention. The following embodiments are merely illustrative of the sewer cover according to the present invention, but are not intended to limit the scope of the present invention.

1 is a schematic perspective view of a sump well to which an exemplary sewer cover according to the present invention is applied, FIG. 2 is a rear perspective view of an exemplary sewer cover according to the present invention, and FIG. 3 is a rotatably mounted on / off valve in a rotation support. 4 is a sectional view of an exemplary sewer cover according to the present invention.

As shown, the sewage cover 1 according to the present invention, like the existing sewer cover is a cover to cover the inlet to the inlet (3) or open type sewer of the sewage collection well (2), basically The cover body 10, a plurality of rotation supports 20 and a plurality of on-off valve 30 is configured to include.

The cover body 10 is a part which forms the entire frame of the sewer cover 1, and can be generally formed in, for example, a rectangular parallelepiped using an iron plate or a casting. The cover body 10 is composed of a plurality of frames 12 supporting the upper plate 11 and the upper plate 11 forming the surface from below to form a whole skeleton. In addition, the frames 12 have a predetermined height to form a predetermined space inside the sewer cover 1 by the upper plate 11 and the frames 12.

The top plate 11 is formed with a plurality of drain holes 13 for discharging the running water. Although it is not excluded that only one drain hole 13 is formed, a plurality of regular holes are usually arranged in a vertical and horizontal direction, and the illustrated embodiment shows an example in which 20 are regularly arranged. The illustrated drain hole 13 is circular, but may be formed in other shapes such as a rectangle or an ellipse.

The top plate 11 is provided with mounting holes 14 for mounting the rotation support 20 to be described later. Since each of the drain holes 13 is provided with mounting holes 14 on both sides thereof adjacent thereto, two mounting holes 14 are arranged in one drain hole 13 to form one set.

Rotating support 20 is mounted to each mounting hole 14. The rotation support 20 is a member for rotatably supporting the on / off valve 30 to be described later. The pivot support 20 is preferably formed of a single member, but functionally includes a head 21, a support shaft 22, and a pivot shaft 23.

The head 21 is formed to be larger than the size of the mounting hole 14, so that when the pivoting support 20 is inserted into the mounting hole 14, the pivoting support 20 passes through the mounting hole 14. As a part to prevent, in the example shown, it is formed so that it may protrude a little from the upper plate 11 in rectangular shape.

The support shaft 22 extended from the head 21 is a member for positioning the position of the pivot shaft 23 spaced downward from the upper plate 11, and is elongated to approximately the middle position or more of the frame 12. have.

The rotating shaft 23 is protruded at the end of the support shaft 22, for example, and the opening / closing valve 30 which will be described later is attached to the rotating shaft 23 so as to be rotatable.

Rotating support 20 having the configuration as described above is mounted to each of the two mounting holes 14 assigned to one drain hole 13 to form a pair, the pair of rotation support 20 is a corresponding drain hole 13 The rotating shafts 23 are mounted to face each other with the gaps between them.

On the upper side of the support shaft 22 at the position just below the head 21, a thickening portion 22A forcibly fitted to the mounting hole 14 can be formed. Thus, when the rotation support 20 is inserted into the mounting hole 14 and the head 21 is hit by a rubber hammer or the like, the thickening portion 22A is tightly fitted into the mounting hole 14 so that the rotation support 20 is intended. It does not fall out of the cover body 10 so as not to.

In addition, since the mounting hole 14 is a square (square) and the rotation support 20 mounted here is also a square (square) which cannot be rotated in the mounting hole 14, the mounting hole 14 is carried out. When the pivot support 20 is inserted into and fixed to the pivot shaft 23 of the pivot support 20, which is formed as a pair, so as to exactly face each other, no additional work for adjusting the shaft center of the pivot shaft 23 is required. .

An on-off valve 30 is rotatably mounted between the rotation shafts 23 of the pair of rotation support members 20 facing each other. The on-off valve 30 is a member that selectively opens and closes the drain hole 13 of the upper plate 11, and normally closes the drain hole 13 to prevent inflow of filth and backflow of odor or pest, and when there is running water, It is a plate that is opened by the load of water and flows into the sewer.

The on-off valve 30 preferably consists of a single plate, but functionally includes an open / close plate 31, a support plate 32, a bearing 33 and a weight 34.

The opening and closing plate 31 is a portion that directly opens and closes the drain hole 13 from the bottom, and has a size slightly larger than that of the drain hole 13. If dirt with a load is accumulated on the open / close board 31, the open / close board 31 may be opened by the dirt load even though there is no running water. Therefore, the opening and closing plate 31 is preferably formed convexly upwards so that the dirt dropped thereon does not remain as possible.

The support plate 32 is bent at a certain angle (eg, 90 degrees) with respect to the opening and closing plate 31. The supporting plate 32 supports the opening and closing plate 31 so that the opening and closing plate 31 can be opened and closed smoothly by the load of the flowing water and the gravity W of the weight 34.

The bearing 33 is formed in the support plate 32, and the rotation shaft 23 is rotatably inserted therein, and the opening and closing plate 31 is rotated with the rotation shaft 23 as the axis to open the drain hole 13. It will open and close. The bearing 33 may be formed by cutting a part of the support plate 32, for example, but considering the fact that the protruding length of the pivot shaft 23 is not long, the bearing plate 33 is disposed on both sides of the support plate 32 as shown. It is preferable to form by protruding and bending.

The weight weight 34 is fixed to the end part of the support plate 32 at the opposite position of the opening and closing plate 31 about the bearing 33. The weight 34 may be fixed to the support plate 32 by welding or the like, but as shown in the figure, fixing the weight 34 by wrapping the support plate 32 may eliminate or minimize the welding process. Do.

When the flowing water flows down, the load of the flowing water is applied to the opening and closing plate 31 to overcome the load of the weight 34 and open the drain hole 13 so that the drainage is made, the opening and closing plate 31 is It is possible to open as far away as possible from the drain hole 13 at a large angle so that the on-off valve 30 (ie, the on-off plate) acts as a resistance to the flow of the flowing water or the on-off valve 30 is bent by an external force. It is preferable in that it can minimize the problem of being unable to maintain a closed state normally.

From this point of view, it is preferable to position the pivot shaft 23 as far as possible from the upper plate 11 and as far as possible from the drain hole 13 in the horizontal direction within the range that does not prevent the opening and closing of other adjacent valves 30. It is preferable to enlarge the opening angle of (31).

That is, when the on-off valve 30 is opened, the opening and closing plate 31 is lowered around the pivot shaft 23 and the weight 34 is upward, the limit of the opening angle of the opening and closing plate 31 is The weight 34 is caught by the bottom of the top plate 11 until its upper movement is restricted. Therefore, when the pivot shaft 23 is positioned far away from the upper plate 11, the weight 34 can be rotated to an upper portion higher than the height of the pivot shaft 23, so that the opening angle of the opening and closing plate 31 is increased. It can be made larger than 90 degrees.

Of course, before the weight 34 is rotated to a position directly above the rotation shaft 23, the upper plate 11 should be caught by the force of the load to open and close the closing plate 31 to close. In addition, the weight 34 has a weight enough to close the drain hole 13 by rotating the opening and closing plate 31 to a horizontal position when no load is applied to the opening and closing plate 31.

Sewer cover according to the present invention as described above has the following effects.

First, since the mounting hole 14 is drilled in the upper plate 11 and the rotation support 20 is inserted therein to provide the rotation shaft 23 of the on-off valve 30, so that the on-off valve 30 is mounted. There is no need for a separate operation for aligning the axial center of the coaxial 23, and thus it is easy to install the on-off valve 30 so as to be rotatable.

Second, since the opening angle of the on-off valve 30 reaches approximately 90 degrees or more, it is possible to minimize the on-off valve acting as a resistance when a large amount of running water flows, and even if an unintentional force is applied from the outside. Since the open / close valve 30 is not bent by an external force while being opened more than 90 degrees, the problem that the open / close valve 30 remains open without being normally closed by bending of the open / close valve 30 does not occur.

Third, since the opening and closing plate 31 of the opening and closing valve 30 is convex upward, it is possible to minimize the accumulation of dirt on the opening and closing plate, thereby preventing opening of the opening and closing valve due to the accumulation of dirt.
