In this case, the detection of the water level is carried out by a buoy, and one end of the rotating member rotated while the buoy is raised together with the rise of the water level does not rotate the wing of the water gate so that it cannot be drained through the drain hole and to the outside. Since it is drained, since it does not apply a load to this drain, it is preferable.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

The non-powered hydro gate opening and closing manhole according to an exemplary embodiment of the present invention is largely composed of a body 100, a hydro gate 110, and a water level detecting unit 112 as shown in FIGS. 1 to 3.

The body 100 is provided in the middle of the drainage pipe 10, the drain hole 102 connected to the drainage pipe 10 is formed on one side in the buried state, the inlet connected to the drainage pipe 10 on the other side ( 104 is formed.

Here, an extension part 104 is further formed in the drain hole 102 of the body 100, and a manhole cover 108 formed by perforation is seated on the upper surface of the body 100.

Furthermore, the upper end of the extension portion 104 is provided to further protrude upwards, the groove 104a is formed at the central end of the protruding edge is connected. In addition, the inlet of the groove 104a may be partially cut out to increase the rotation angle of the rotation member 116 to be described later.

In addition, a hole is formed in the groove 104a of the extension part 104 so that one end of the rotating member 116 of the water level sensing unit 112, which will be described later, is fixed by a hinge H inserted into the horizontal direction. A hole 114b is formed in a horizontal direction on both circumferential surfaces of the central portion, and the shaft 110a of the water gate 110 to be described later is inserted.

The water gate 110 is rotatably provided in the vertical direction in the extension portion 104 formed in the drain hole 102 is rotated in the drain hole 102 is opened to drain and closed when stopped to prevent drainage Function.

In addition, the water gate 110 is provided with at least one radial wing, and the wing facing the same as the cross-sectional shape of the extension portion 104 is provided so that the area is reduced to the space formed between the extension portion 104 Through a small amount of rainwater is discharged.

Furthermore, the water gate 110 may rotate in the vertical direction in the vertical direction, or may rotate in the horizontal direction in the horizontal direction, and the position of the water level detecting unit 112 does not change even when rotated in the horizontal direction. Do not. (See Figure 4)

In addition, the water gate 110 may be rotated in only one direction, and the shaft 110a protrudes from the center of both ends thereof.

The water level detecting unit 112 is coupled to the upper center groove 104a of the extension portion 104 connected to the drain hole 102 so as to detect the water level in the body 100, the water level of the body 100 is When it reaches the set height and serves to stop the rotation of the water gate 100, it is configured by subdividing the buoy 114 and the rotating member 116.

The buoy 114 is coupled to the other end of the rotating member 116, and is sealed in a hollow state so as to sense the water level inside the body 100, and floats on the surface of the water.

The rotating member 116 is formed with a hole through one end thereof so as to be connected to a hole formed in the groove 104a of the extension part 104, and is coupled to the groove 104a by inserting a hinge (H).

Here, the end of the rotating member 116 proximate to the hinge (H) is provided so as to surround the soft stopper 118 so that one end of the rotating member 116 is raised by the buoy 114 Lowering the hinge (H) as a starting point and moves to the position that interferes with the wings of the sluice (110), and prevents the sluice (110) from colliding in this process.

Furthermore, if the rear end of the rotating member 116 is rotated up to the maximum position, then the front end should be able to be located in the movement trajectory of the water gate 110, and appropriate spacing adjustment is necessary.

Although not shown in the drawing, the shaft 110a of the water gate 110 may be provided with a generator and a battery so as to generate power by itself.

Therefore, the operation process of the non-powered hydrogate opening and closing manhole of the present invention, as shown in Figures 1 to 3, first, the rainwater obtained from the inlet 106 in the state of the water level inside the body 110 in a normal state is hydraulic The water gate 110 is rotated and drained to the drainage pipe 10 through the drain hole 102.

However, due to the heavy rain, the water level inside the body 100 rapidly rises, so that the buoy 114 of the water level detecting unit 112 rises by the water level, and the buoy 114 is connected to the other end of the rotating member 116. One end of) rotates downward from the hinge (H).

Here, one end of the rotating member 116 is rotated downward and positioned inside the wing trajectory of the sluice 110 and interferes with rotation, the rotation of the sluice 110 is stopped.

Thereafter, the water gate 110 is stopped and the drain hole 102 is closed so that the rainwater is not drained to the drain pipe line 10 connected to the drain hole 102.

At this time, the rainwater that is accommodated in the body 100 is separated from the manhole cover 108 from the body 100 and drained to the ground using a pump (not shown in the drawing), etc. To prevent overload caused when discharged through the drain pipe 10 connected to 102. Alternatively, the manhole cover 108 may be flowed back to drain the ground.

According to another embodiment of the present invention, the non-powered door retractable manhole is not shown in the drawing, but in a manner of opening and closing the drain hole 102 by hydraulic pressure, the hinge H at the bottom of the extension part 104 in the previous embodiment. The rear end of the combined rotating member 116 is positioned horizontally or inclined upwardly and has a horizontal plate at the rear end of the rotating member 116 instead of the buoy 114.

That is, when the water level is low because the internal water level of the body 100 is low, the water gate 110 is rotated and drained, but the plate is provided at the original position, and when the water level inside the body 100 is high, the water pressure is increased. As the plate is lowered by the tip of the rotating member 116 stops the rotation of the water gate (110).

As described above, when the water level of the body reaches the set position, the non-powered hydrogate retractable manhole of the present invention can close the open drain and flow back to the outside or drain to the ground to prevent the overload of the drain pipe on the drain side. It works.

In addition, the non-powered hydrogate opening-and-closing manhole of the present invention has the effect of closing the drain by the water gate in a non-powered manner.
