きわめて不便を感じるものである。In the water intake device in which water is taken by closing the irrigation channel 1 'at the sluice 7', dust that is mixed or floating in the water concentrates and flows only in the bypass 2 ', so that the clogging of the dust removing screen 6' can be prevented. Easy to occur. Also, the screen 6 '
It is inevitable that the fine earth and sand flowing through the eyes will flow into the intake chamber. Furthermore, even when the water intake is temporarily interrupted or during a long period of non-use of the water intake device, the water always flows through the bypass passage 2 ', and the dust removing screen 6' is always kept submerged under the water surface. Therefore, in order to remove sediment easily deposited in the intake chamber and dust and dirt deposited on the screen surface and stuck on the screen surface, sandbags are piled up in the bypass passage 2 'to prevent the flow of water. The work must be carried out after draining, which is extremely inconvenient for maintenance.

When the inside of the introduction groove 2 reaches a predetermined water level, the water in the water intake chamber 3 is pumped by the drive of the submersible pump 9 and supplied to a predetermined use place. The earth and sand mixed in the inflow water is blocked by the sand dam 4 and remains in the sand basin 5. Dust mixed or floating in the water flowing over the sand control weir 4 moves to the reflux side 2b along the inclined surface of the dust removal screen 6, merges with the water in the irrigation channel 1, and flows downstream. If the inside of the introduction groove 2 descends to the predetermined water level, the backwash nozzle
The washing of the washing water from 10 詰 10 prevents the screen 6 from clogging. When the water intake device is not used, the sluice 6a is closed.

実施例の場合と同じである。In the embodiment of FIG. 2B, when the floodgate 7b is closed, the water level in the introduction groove 2 rises. Once the water level is reached,
The water in the water intake chamber 3 is pumped by the drive of the submersible pump 9 and supplied to a predetermined use place. When the amount of inflow water into the introduction groove 2 exceeds the intake amount, the floodgate 6b is opened to adjust the water level. The operation of the sand dam 4, the operation of the dust removing screen 6, and the operation of the backwash nozzle 10 # 10 are the same as those in the embodiment of FIG. 2A.

合と同じである。In the embodiment of FIG. 2C, when the water gate 7a on the inflow side 2a is opened and the water gate 7b on the reflux side 2b is closed, the introduction groove 2 is formed.
The water level inside rises. When the water level reaches a predetermined level, the water in the water intake chamber 3 is pumped by the drive of the submersible pump 9 and supplied to a predetermined use place. When the amount of inflow water into the introduction groove 2 exceeds the intake amount, the water gate 7a on the inflow side 2a is closed or the water gate 7b on the return side 2b is opened to adjust the water level. The function of the sand dam 4, the function of the dust screen 6 and the backwash nozzle 10 mm
The operation of # 10 is the same as that of the embodiment of FIG. 2A.

わめて便利である。[Effects] According to the water intake apparatus of the present invention, since water always flows through the irrigation channel 1 during water intake, most of the dust mixed or floating in the water is caused to flow downstream by the irrigation channel 1. And water intake room 3
The upper dust-removing screen 6 is inclined downward toward the recirculation side 2b, and a backwash nozzle 10 # 10 communicating with the pump discharge port 9b is opened to the lower surface of the dust-removing screen 6. Therefore, clogging of the screen 6 can be prevented, and accumulation of dust can be prevented in combination with the fact that water does not pass through the introduction groove 2 during the non-use period. In addition, since the sediment is blocked by the sand dam 4, the sand does not enter the water intake chamber 3 through the eyes of the screen 6. When it becomes necessary to clean the dust removing screen 6 and the water intake chamber 3, the water gates 7a and 7b are closed and the water conduit 2 is closed.
It is very convenient for maintenance because the inside can be drained.
