Description
Technical Field
The invention relates to the technical field of flap dam control, in particular to a magnetic flap dam.
Background
The flap dam on the market at present mainly adopts a hydraulic self-balancing mode, and has the advantages of being completely automatically controlled by hydraulic power and needing no energy. But has a disadvantage in that adjustment after setting the water level is difficult.
As shown in fig. 1, the conventional flap dam comprises a dam body 1 and a concrete baffle 4 fixed on the river ground, wherein the concrete baffle is arranged according to the needs of the site, for example, a laid triangular column, and the axis of the triangular column is horizontal or parallel to the river ground; the first surface of the axial outer wall of the triangular column body is arranged on the ground of a river channel, the second surface of the axial outer wall of the triangular column body is a water-facing surface, the third surface of the axial outer wall of the triangular column body is a water-receiving surface, the bottom of the dam body is arranged on the water-facing side of the concrete baffle body, the dam body is pressed by incoming water to the water-facing surface of the concrete baffle body, and the bottom of the dam body leans against the water-facing surface of the concrete baffle body; the middle part of the dam body is provided with a dam body rotating shaft along the horizontal line, the dam body rotating shaft is rotationally connected with the dam body, and two ends of the dam body rotating shaft are respectively fixed on two banks of the river channel;
usually, the dam body rotating shaft is related to the dam body opening water level height set according to the position height of a river channel, and the higher the rotating shaft is, the higher the water level of the dam which is finally automatically opened is. When the rotating shaft is X, the dam body is automatically opened when the water level is higher than 3.414X; when the water level is lower than the overturning shaft of the dam body, the water pressure only presses the dam body to close the dam body. When the water level is higher than the dam rotating shaft, and the water level of the upstream surface of the dam is gradually increased, the opening force (clockwise torque (opening torque)) generated by water on the upper part of the dam is gradually increased and finally exceeds the closing force (anticlockwise torque (closing torque)) caused by the water pressure on the lower part of the dam in fig. 1, if the dam rotates clockwise and opens in fig. 1, but according to the direction of water flow, the situation of reverse rotation exists, when the opening force reaches a torque balance point or above, the dam rotates around the dam rotating shaft, the bottom is opened, and water flows out. When the upstream water level of the dam body drops below the opening torque balance point, the dam rotates anticlockwise (rotates reversely) and is closed.
At present, the traditional turnover dam is mainly used for adjusting the torque characteristic of a dam body by adjusting the position of a turnover shaft and adding a part of balance weight on the dam, for example, a heavy object such as concrete is added below a rotating shaft, so that the closing torque is increased, and the opening water level is improved. The starting torque is increased and the starting water level is reduced by adding the counterweight at the top (the counterweight is arranged at different positions and the arm of force is different); however, this method is inconvenient and has poor adjustment precision. In addition, the dam state is usually located near the torque balance point, the dam will be closed, and the influence of the upstream water waves is serious.
The opening water level of the traditional flap dam is difficult to adjust after construction, the flap dam is opened towards the upstream face from the bottom of the dam body, and sundries such as branches carried by water flow are easily clamped at the bottom of the dam body, so that the dam body cannot be closed. And because of adopting full mechanical device, whether the dam body is blocked can not the remote monitoring, only adopt other auxiliary device or on-the-spot to look over and can discover.

A plurality of electromagnets which are mutually independent are arranged on each turnover dam, and the electromagnets with different numbers are started to correspond to different turnover dams to start water levels. The power supply of each electromagnet is controlled by the switching value output by the relay of the PLC. The PLC communicates with the computer through a bus or network. Any relay output port of any PLC can be controlled through PLC control software or configuration software on a computer, any appointed electromagnet power supply can be turned off or turned on, and then the total magnetic force provided by electromagnets on all flap dams is controlled, and multi-stage adjustment of water level control of the flap dams is achieved.
If the analog quantity output module of the PLC is used for control, the adjustment of the magnetic force of the electromagnet with higher precision can be realized by adjusting the power supply voltage and the current of the electromagnet. However, in consideration of the actual control precision requirement on site, the high-precision adjustment of the attraction force of the electromagnet is not required in general.
The opening water level of the dam body is completely determined by the electromagnetic force, the dam body can be remotely and quickly adjusted, and the dam body is opened on the back surface and is not easily clamped by sundries. In addition, whether the flap dam is opened or not can be indirectly monitored by monitoring whether the magnetic device is opened or not.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
