In the prior art, the utility model patent CN215289901U discloses an ecological water discharging device of a reservoir, which comprises a dam top and a dam body, wherein a water inlet pipe is arranged on the dam body and is connected with a water outlet pipe through an ecological maintenance valve and an ecological working valve; the top of the dam is provided with an air pipe, the air pipe is connected with the water inlet pipe, the middle part of the air pipe is provided with an air pipe electric valve and an air pipe working valve, and the air pipe working valve is connected with the vacuum pump through the air pipe; the downstream water inlet pipe of the dam is connected with an exhaust pipe, and the exhaust pipe is connected with an exhaust valve through an air pipe maintenance valve; a flowmeter is arranged on the water inlet pipe at the downstream of the dam.
However, in the prior art, the exhaust device and the valve control device are both arranged on the side surface of the dam body or at the water outlet pipe, the device has low separation linkage, the starting and stopping are complicated, and the device is not easy to overhaul when the device fails.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a dam water discharge structure to solve the problems of water discharge.
The utility model provides a dam water discharge structure, which comprises the following structures: including dam body and drain pipe, be provided with the drain pipe on the dam body, the drain pipe is taken on the dam body, the drain pipe both ends are in the dam body both sides respectively, be provided with flow sensor on the drain pipe of dam body top, connect the pump through the bypass pipe on the drain pipe at flow sensor rear, the pump passes through the bypass pipe and connects on the drain pipe, be provided with the valve on the drain pipe at pump rear.
The flow rate sensor is connected with the flow rate controller, the flow rate controller is connected with the pump through a control line, and the pump is controlled to start and stop through the flow rate controller.
One side of the dam body is an upstream, the other side of the dam body is a downstream, and a net cage is arranged at the inlet of a water drain pipeline at one side of the upstream.
The inlet of the water drain pipeline is lower than the upstream water level line, and the outlet of the water drain pipeline is lower than the downstream water level line.

As shown in fig. 1-2, the present utility model provides a dam drainage structure, which comprises: the dam comprises a dam body 1 and a water drain pipeline 2, wherein the water drain pipeline 2 is arranged on the dam body 1, the water drain pipeline 2 is lapped on the dam body 1, two ends of the water drain pipeline 2 are respectively arranged on two sides of the dam body 1, a flow rate sensor 11 is arranged on the water drain pipeline 2 above the dam body 1, the water drain pipeline 2 behind the flow rate sensor 11 is connected with a pump 8 through a bypass pipeline 7, the pump 8 is connected with the water drain pipeline 2 through the bypass pipeline 7, and a valve 9 is arranged on the water drain pipeline 2 behind the pump 8;
the flow rate sensor 11 is connected with the flow rate controller 5, the flow rate controller 5 is connected with the pump 8 through the control line 6, and the pump 8 is controlled to start and stop through the flow rate controller 5;
one side of the dam body 1 is an upstream, the other side of the dam body 1 is a downstream, and a net cage 3 is arranged at the inlet of a water drain pipeline 2 at one side of the upstream;
the inlet of the water drain pipeline 2 is lower than the upstream water level line 4, and the outlet of the water drain pipeline 2 is lower than the downstream water level line 10;
the pump 8 is a flowmeter control pump 8;
the valve 9 is an electromagnetic valve;
specifically, when the dam needs to be drained, the valve 9 is opened, the pump 8 is started, when the flow rate sensor 11 in the water drain pipeline 2 monitors that the flow rate of water reaches the set value of the flow rate controller 5, the flow rate controller 5 controls the pump 8 to stop, the water drain pipeline 2 automatically drains through the upstream and downstream high-low water level difference, and when the dam needs to store water, the valve 9 is closed.
