Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention stores the water taken from the river against floating clay that accumulates in the waterway of the tidal section and adversely affects the floodgate facilities, and discharges it to form a miosuji (formed by the flow of water in the lagoon). The present invention relates to a non-powered sweeping device for the purpose of forming a groove) and preventing the accumulation due to its action.

[0002]

[Prior art]

 On agricultural land near the sea, a sluice is installed to prevent seawater from flowing back into the river at high tide.However, when the tide is high, sludge and floating clay come along with the tide and only the tide is pulled at low tide. As a result, sludge and suspended clay tend to accumulate on the downstream side of the lock. The accumulation of floating clay in this way may impair the opening and closing of sluices, resulting in unexpected harm.

Conventionally, as a device for preventing the accumulation of floating clay, an underwater pump is operated to apply pressure-fed water to the accumulated clay or directly suck it up to remove it. , Requires power. In addition, the effect of miosuji, which is naturally formed by falling water flowing into rivers, can prevent a certain amount of clay accumulation, but its effect is small when the rainfall is small.

[0004]

[Problems to be solved by the device]

 Therefore, in order to solve the conventional problems, the present invention provides a powerless sweeping device configured to naturally store river water and discharge it without using external power at low tide to form a myosuji. It is a thing.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the non-powered flushing device of the present invention is installed on the downstream side of a floodgate, and has a suction tank for collecting tap water from a river, and a water storage tank connected to this suction tank for storing water. Provided in the float chamber for operating a float chamber attached to the water storage tank for storing water from the suction tank and an opening plug for opening and closing a discharge port provided at the bottom of the water storage tank The float, a valve that opens and closes the water inlet provided at the bottom of the float chamber by an external water level, and the outlet at the bottom of the water storage tank are connected, and the water in the water storage tank is connected to the water channel downstream of the water gate. It is equipped with a water pipe that discharges water.

Since the present invention is configured as described above, water is stored in the water storage tank and the float chamber at high tide, and at low tide, the water level in the float chamber is gradually discharged by the valve at the bottom of the float chamber. When the water level reaches a predetermined level, the water in the water storage tank is discharged from the water pipe into the waterway. The released water causes myosuji to form on the sedimentary clay at the bottom of the canal. After that, the flow concentrates on the part of the myosuji causing scour, the depth of erosion becomes deep, and the clay becomes liable to collapse. Can be prevented from accumulating.

[0007]

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 show an embodiment of the present invention, the main parts of which are a suction tank 1 for collecting tap water of river water, a storage tank 2 for storing water, and a storage tank bottom for detecting a control water level. The float chamber 3 has an opening of the stopper 27, the water supply pipe 4 for supplying water in the water storage tank 2 and discharging the water.

As installation conditions, if there is a certain difference in the water level of the river water, the intake water level 6 is secured by high tide, and the device installation channel bottom 8 is exposed at low tide, a natural river, population Water channel.

FIG. 3 shows a state of water intake into the device. The water level increased from the bottom 8 of the water channel is the ball tap valve sensing water level 5, and the ball tap valve 28 attached to the bottom of the float chamber 3 is the ball float. The float chamber 3 is closed by the buoyant force of the above and the water can be stored in the float chamber 3. When the water level further increases and reaches the intake water setting level 6, clean water with a low content of suspended clay passes through the screen 9 and is taken in by the suction device 10.

As shown in FIG. 7, the suction device 10 comprises three elements, that is, a small screen 11, a float valve 12, and a suction pipe 13. The small screen 11 having a screen pitch smaller than that of the screen 9 prevents dusts passing through the screen 9 from entering the device. The float valve 12 is rotatably attached by a valve adjusting rod 14 and a valve support member 15, and normally descends by its own weight to open the water intake 16 and take water. However, since the suction device 10 is not limited to the illustrated embodiment, it is possible to cope with various intakes of tap water by changing its design as described later.

The taken water passes through the suction pipe 13 and is carried into the water storage tank 2. In the water storage tank 2, the water storage capacity can be changed by adding another tank to the connection flange 17 with the suction device 10. The bottom of the water storage tank 2 is provided with an inclination of 10 ° to 15 ° so that the deposits in the tank can be swept away when discharged. The water carried to the water storage tank is discharged from the water discharge port 18 because the water discharge port 18 at the bottom of the water storage tank 2 is in an open state. The amount of water increases and flows from the connection port 19 into the float chamber 3 where water can be stored.

The bottom of the float chamber 3 is provided with an inclination of 10 ° to 30 ° so that the indoor sediments can be swept away when the float control discharge is performed.

Water is not taken into the device from any place other than the suction device 10. Even if the river water level increases due to the action of the check valve 31 installed in the middle of the water pipe 4, the water pipe 4 No water is taken from.

FIG. 4 shows a state where the water storage in the apparatus is completed. When the water in the float chamber 3 increases, the float sensing water level 7 is reached, and the float adjusting rod 21 and the float support metal object are placed in the float chamber 3. The float 20 rotatably attached by 22 rises by buoyancy. The float adjusting rod 21 is rotatably attached to the opening stopper adjusting rod 25 and the opening stopper supporting metal 26 in the water storage tank 2 via the connecting rod 24 and the connecting rod support metal 23.

As the float 20 rises, the opening stopper adjusting rod 25 and the opening stopper 27 are lowered with the connecting rod supporting metal member 23 as a fulcrum, the outlet 18 is closed, and water can be stored in the water storage tank 2. As for the water taken in, the suction chamber 10 is filled with water by filling the float chamber 3 and the storage tank 2 with water. When the suction device 10 becomes full of water, the float valve 12 rises due to buoyancy and the intake 16 is closed, and when the river water level outside the device becomes high, a device for river sewage with a high floating clay content Prevent intrusion and prevent the accumulation of suspended clay in the equipment. The air inside the apparatus is exhausted from the air vent pipe 30 located above the float chamber 3.

FIG. 5 shows a float-controlled discharge state. When the river water reaches the ball tap valve sensing water level 5 from high tide to low tide, the ball tap valve 28 attached to the bottom of the float chamber 3 is , The ball float descends by its own weight and opens to allow the water in the float chamber 3 to be released little by little. The water discharged from the ball tap valve 28 is carried to the sweep plate 29 by the water supply hose 33, and sweeps the lower part of the float chamber 3.

FIG. 6 shows the state of discharge for forming myosuji. While the water level in the float chamber 3 gradually decreases due to the float control discharge (for example, after 1 hour has elapsed), The water reaches the low tide and the channel bottom 8 is exposed. After that, after the water level in the float chamber 3 reaches the float sensing water level 7 set by the float adjusting rod 21, the float 20 descends by its own weight, and the float adjusting rod 21 passes through the connecting rod 24 to support the connection. With the metal fitting 23 as the fulcrum, the opening stopper adjusting rod 25 and the opening stopper 27 rise, the outlet 18 is opened, the water in the water storage tank 2 is sent to the water supply pipe 4, and the backflow prevention is installed in the middle of the pipe. After passing through the valve 31 and the water control valve 32, the water is discharged from the end of the water pipe to form the myosuji 37.

As described above with reference to one embodiment, the present invention is characterized by repeatedly storing water and discharging it by utilizing the difference in the level of the river water during ebb and flow. The specific embodiment is not limited to the above embodiment, but can be variously changed.

For example, depending on the accumulation situation at the implementation site, if necessary, an additional water storage tank may be added, or the suction device 10 may be provided with a telescopic hose 35 and a float 36 as shown in FIG. 8 in accordance with the water level condition of the river. It can be widely implemented by taking measures such as raising and lowering it according to the tidal water level of the river to take in clean water, and installing multiple pipes of the water pipe 4 and installing a spout nozzle at the end of the pipe.
