Description

{Waste water discharging system of weir}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system for discharging a weir in a river or a coast, and more particularly, to a system for discharging the overflow flowing into a river dam in a rainy season to a river or a coast.

Generally, the city's daily sewage is collected through sewage pipes, purified at sewage treatment plants, and then discharged to rivers and coasts. However, when a large amount of rainwater is mixed with domestic sewage into a sewage treatment plant due to rain, it may cause contamination of streams and coasts due to incomplete purification exceeding the purification capacity of the sewage treatment plant, and breakage of the subassembly may occur .

Thus, there is known a system for opening and closing an excellent can according to a flow rate flowing through a sewer pipe. That is, when the flow rate of the sewage flowing through the sewage pipe is small, the sewage well is opened and the sewage is introduced into the sewage treatment plant through the sub-pipe connected to the good sewer. However, when the flow rate of the sewage flowing through the sewer pipe is large, the excellent sewer pipe is closed and a large amount of sewage discharged from the sewer pipe flows downward into the river and the coast beyond the weir.

The weir, on the other hand, has an upper jaw of constant height to prevent safety accidents and to prevent the inflow of contaminants such as sludge contained in the sewage. However, due to the upper jaw, contaminants accumulate in the vicinity of the upper jaw after the rains of the sewage are introduced into the river or the shore in case of rain, resulting in poor appearance and hygiene, causing environmental pollution and odor.

The plurality of upper jaws 12 are connected to a water weir 11 which forms the boundary between the water in the waterfront area and specifically the river 1 and the land, See Figs. 4 and 5). A plurality of upper jaws 12 are provided, which are elongated in a row, but are not connected to each other but are separated and spaced apart from each other to be spaced apart from each other. A sewage discharge door (40) is disposed between a pair of adjacent upper and lower jaws (12). The plurality of upper jaws 12 serve to block the sewage flowing from land, specifically from the bottom of the sewer channel 15 to the water, specifically to the stream 1.

The storage tank 20 is provided adjacent to the plurality of upper jaws 12. Specifically, in the illustrated embodiment, a side wall 19 is protruded from a plurality of upper jaws 12 extending in a row in a direction blocking the last upper jaw 12, and a storage tank 20 Is formed. When the sewage flows down to the bottom 15 of the sewage flow channel in the rain, the sewage drained by the plurality of upper jaws 12 and the closed sewage discharge door 40 and the sewage contained therein, such as sludge, Of the contaminants are introduced into the storage tank 20 and filled.

A metal sash can be installed at the inlet 23 of the storage tank 20 formed in the side wall 19 to prevent safety accidents and the introduction of bulky waste (refer to FIG. 2). A sloping bottom 17 for guiding the inflow of sewage to the storage tank inlet 23 can be formed in the boundary region between the storage tank inlet 23 and the drainage channel bottom 15. [

3, the storage tank 20 is provided with an inlet 23 opened on the side wall and an outlet 25 opened to the side of the stream 1 (see FIG. 1), and an inlet 23 and an outlet 25 are provided. A storage space 21 is provided. The storage space 21 is deeply dug down so that the level of the bottom of the storage space 21 is lower than the level of the inlet 23 and the outlet 25. When the sewage flows down into the plurality of upper jaws 12 in a rainfall, it is blocked by the plurality of upper jaws 12 and the closed sewage discharge door 40 and flows into the storage tank inlet 23.

Relatively small heavy stones or sand remain in front of the plurality of upper jaws 12 and the closed sewage discharge door 40 but the contaminants S such as sludge and other wastes such as muddy suspended matter are relatively light, And flows into the reservoir inlet 23 and is deposited in the retention space 21. When the storage space 21 is filled with sewage, contaminants S such as sludge and waste accumulate on the bottom of the storage space 21 and the polluted sewage is discharged to the river 1 through the outlet 25 .

The storage space 21 is provided with a water level meter 26 for measuring the level of the sewage water to be received. The level information of the storage space 21 measured by the water level meter 26 is transmitted to a motor controller 75 (see Figs. 4 and 5) to be described later. On the other hand, when the contaminant S is filled in the storage space 21, it is collected through a storage tank inlet 23 or a manhole (not shown) and is buried or recycled at a designated place.

 Fig. 4 is a front view showing the sewage discharge door of Fig. 1, and Fig. 5 is a cross-sectional view cut along the line V-V of Fig. 1, 4 and 5, the sewage discharge door 40 is connected to the water 1 from the land 15 via the sewage discharge passage 14 between the adjacent pair of upper jaws 12, A door plate 42, an air tank (not shown) for closing the space between a pair of upper jaws 12 adjacent to each other and a pair of upper jaws 12 adjacent to each other, A motor 45, a motor 60, and a locking cam 50.

The door plate 42 is deflected in a direction to close the sewage discharge passage 14 between the upper jaws 12 of the adjacent one of the upper and lower frames. More specifically, a hinge shaft 48 is attached to a hinge shaft 48 rotatably supported at both ends thereof by a pair of hinge shaft supporters 49 fixed to a pair of upper jaws 12 adjacent to each other. do. On the basis of the hinge shaft 48, one side of the door plate 42 is heavier than the other side. As a result, the heavy side of the door plate 42 contacts the bottom 15, and the sewage discharge passage 14 is closed. Hereinafter, the heavy side of the door plate 42 is referred to as a lower end, and the opposite side thereof is referred to as an upper end. On the other hand, the door plate 42 in a state of closing the flow path 14 is inclined so as to be connected to the inclined surface on the land 15 side of the upper step 12 having a trapezoidal cross-sectional shape.

The air tank 45 is installed at the lower end of the door plate 42. When the level of the bottom of the drainage channel 15 becomes higher than the air tank 45 when the door plate 42 is closed by the weight of the lower end of the door plate 42, the buoyancy of the air tank 45 and / The lower end of the door plate 42 on which the air tank 45 is installed is raised. Then, the door plate 42 is rotated clockwise along the arrow in FIG. 5 to open the drainage discharge passage 14, and the sewage is discharged directly from the bottom of the drainage passage 15 to the river 1.

The locking cam 50 has a locking position for locking the door plate 42 closing the sewage discharge passage 14 and a locking position for moving the door plate 42 in the direction of opening the sewage discharge passage 14 And an unlocking position in which the locking cam 50 is unlocked, and the motor 60 provides rotational power for rotating the locking cam 50. [ Concretely, both ends of the camshaft 53 are rotatably supported on a pair of camshaft supports 54 supported on the upper surfaces of the pair of upper jaws 12, The disc-shaped locking cam 50 is eccentrically supported. The cam shaft 53 rotates counterclockwise by 180 degrees with reference to Fig. 5, so that the locking cam 50 rotates to the locking position and the unlocking position.

The upper end 44 of the door plate 42 extends to contact the locking cam 50. The locking cam 50 shown by the solid line in FIG. 5 shows the locking position so that the upper end 44 of the door plate 42 contacts the locking cam 50 and prevents the door plate 42 from rotating in the clockwise direction It is blocked. On the other hand, in FIG. 5, the locking cam 50 shown by the chain double-dashed line represents the unlocking position, and the locking cam 50 is raised so as not to touch the upper end portion 44 so that the door plate 42 rotates clockwise .

The sewage discharge door 40 further includes an upwardly extending bracket 57 which is secured to the upper jaw 12 to surround one of the pair of camshaft supports 54. Reference numeral 58 denotes a support for structurally supporting the bracket 57 so as not to collapse. The motor 60 is fixedly supported at the upper end of the bracket 57 so as not to be submerged by sewage. A pulley 61 is coupled to the shaft of the motor 60 and a pulley 62 is coupled to one end of the camshaft 53 blocked by the bracket 57. The pair of pulleys 61, 61, 62 are connected by a timing belt 65 so as to transmit power. The power of the motor 60 is transmitted to the camshaft 53 by a pair of sprockets and a chain instead of the pair of pulleys 61 and 62 and the timing belt 65 .

The driving of the motor 60 is controlled by the motor controller 75. The motor controller 75 is configured to receive the water level information of the storage space 21 (see FIG. 3) transmitted from the water level meter 26 (see FIG. 3) 3) is recognized as being filled up to a preset level, the control of the driving of the motor 60 so that the locking cam 50 rotates from the locking position to the unlocking position. For example, the predetermined water level may be a water level when the storage space 21 is full. On the other hand, a solar cell 70 (see FIG. 3) may be provided to provide energy for driving the motor 60. The solar cell 70 is a device for converting solar energy into electric energy, and is integrated into a solar cell module in the form of a flat plate. The solar cell 70 is installed in an area where the time of exposure to sunlight is long and there is no danger of flooding by sewage. Although not shown in the drawing, a battery may be further provided for storing electric energy produced by the solar cell 70 and for supplying stored electric energy when the motor 60 is required to be driven. In the present invention, the energy for driving the motor 60 is not necessarily supplied only by the solar cell 70, but may be configured to be supplied with energy by an exchangeable battery (not shown).

5, when the door plate 42 is in a state of closing the sewage drainage passage 14 as shown by the solid line, the locking cam 50 is moved to the upper position And the door plate 42 can not rotate clockwise or counterclockwise in this state. However, a large amount of wastewater flows down to the bottom 15 of the drainage channel (see Fig. 1) due to rain and flows into the storage tank 20 (see Fig. 3), so that the storage space 21 ), The motor controller 75 recognizes the water level information of the water level meter 26 and drives the motor 60. The driving force of the motor 60 is transmitted to the locking cam 50 through the pulley 61, the timing belt 65, the pulley 62 and the camshaft 53 so that the locking cam 50 is moved to the cam shaft 53 (See Fig. 5) and rotates to the unlocking position. The drainage channel bottom 15 is also filled with sewage so that the water level becomes higher than the lower end of the door plate 42 and the locking cam 50 is moved to the unlocking position and the door plate The door plate 42 rotates clockwise (see FIG. 5) and the sewage discharge passage 14 is opened because buoyancy acts on the air tank 45 because the door 42 is rotatable.

When the sewage flows down to the vicinity of the upper jaw 12 due to a large amount of rain, the sewage flowing into the bottom 15 of the sewage channel at the beginning generally contains a large amount of pollutant S, The sewage is relatively low in pollutant concentration. 3) is filled with the initial sewage and then discharged through the sewage discharge passage 14 when the sewage discharge door 40 is opened, The adverse effect on the pollution of the river 1 is small. When the sewage discharge door 40 is opened, the sewage discharge door 40 is relatively heavier than the pollutant S (see FIG. 3) such as sludge so that it can not flow to the storage tank 20 and the upper jaw 12 and the closed sewage discharge door 40 are closed. A small stone or sand accumulated in the front is discharged to the river 1 through the opened drainage door 40 to clean the drainage channel bottom 15.

On the other hand, if all of the sewage is discharged through the sewage discharge passage 14 and there is no freshly introduced sewage, the door plate 42 rotates counterclockwise due to the weight of the lower end of the door plate 42 The flow path 14 is closed. The manager can return the locking cam 50 to the locking position by man power or by driving the motor 60 as part of the maintenance work of the clear water day drain system 10 on a clear day.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
