Description
Technical Field
The invention relates to the technical field of flap dam control, in particular to a magnetic flap dam.
Background
The turning plate dam in the market at present mainly adopts a hydraulic self-balancing mode, and has the advantages of being completely controlled by hydraulic power automatically and needing no energy. But has the disadvantage of difficult adjustment after setting the water level.
As shown in fig. 1, the conventional flap dam comprises a dam body 1 and a concrete baffle body 4 fixed on the ground of a river channel, wherein the concrete baffle body is arranged according to the field requirement, for example, is a laid triangular column body, and the axis of the triangular column body is horizontal or parallel to the ground of the river channel; 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 an upstream surface, the third surface of the axial outer wall of the triangular column body is a passive surface, the bottom of the dam body is arranged on the upstream side of the concrete baffle body, the dam body is pressed towards the upstream surface of the concrete baffle body by the incoming water, and the bottom of the dam body is abutted against the upstream surface of the concrete baffle body; the middle part of the dam body is provided with a dam body rotating shaft along a 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 a river channel;
generally, the position height of the dam body rotating shaft is related to the height of the dam body opening water level set according to the requirements, 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, and the water surface is higher than 3.414X, the dam body is automatically opened; when the water level is lower than the overturning shaft of the dam body, the water pressure only presses the dam body to enable the dam body to be closed. When the water level is higher than the rotation axis of the dam body, when the water level of the upstream surface of the dam body is gradually increased, the opening force (clockwise torque (opening torque) in fig. 1) generated by the water on the upper part of the dam body is gradually increased, and finally the closing force (anticlockwise torque (closing torque) in fig. 1) caused by the water pressure on the lower part of the dam body is exceeded, the dam body rotates clockwise and is opened as in fig. 1, but according to the direction of the water flow, the situation of reverse rotation exists, when the opening force reaches above the torque balance point, the dam body rotates around the rotation axis of the dam body, the bottom is opened, and the water flows out. When the upstream water level of the dam body falls below the opening torque balance point, the dam rotates anticlockwise (rotates reversely) and closes.
At present, the traditional turning plate dam mainly adjusts the torque characteristic of the dam body by adjusting the position of a turning shaft and adding partial counter weight on the dam, for example, a piece of concrete and other heavy objects are added below the turning shaft, so that the closing torque is increased, and the opening water level is improved. The opening torque is increased when the counterweight is added at the top, and the opening water level is reduced (the moment arms of the counterweight are different when the counterweight is arranged at different positions); but this way is inconvenient to adjust and has poor adjustment accuracy. And in general, the dam states are all located near the torque balance point, the dam is not closed, and the influence of upstream water waves is serious.
The traditional flap dam opening water level is difficult to adjust after construction, and is opened towards the upstream surface for the dam body bottom, and sundries such as branches entrained by water flow are easy to clamp at the dam body bottom, so that the dam body cannot be closed. Moreover, because the full mechanical device is adopted, whether the dam body is jammed or not can not be monitored remotely, and the dam body can be found only by adopting other auxiliary devices or checking on site.

In this embodiment, an electromagnet or other magnetic devices are disposed at the lower part (or other parts, such as the side part of the dam body) of the dam body to serve as auxiliary adjusting devices of the dam body, and the torque in the anticlockwise direction of the dam body can be adjusted by controlling and adjusting the suction force of the electromagnet through a remote computer, so that the clockwise torque (the torque corresponds to the water level height when the dam body is opened) required by opening the dam body is adjusted. And setting the opening direction of the dam body according to the river channel and the flowing water direction.
When the electromagnet or other magnetic force devices are used as the torque adjusting device of the dam body, the electromagnet adopts finished products, each provides a certain (for example, 10 KN) suction force, a plurality of electromagnets are arranged at equal intervals along the length direction of the dam body, and corresponding numbers are arranged according to specific conditions.
And a plurality of mutually independent electromagnets are arranged on each flap dam, and different numbers of electromagnets are started to correspond to different flap 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 via 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 specified electromagnet power source can be turned off or turned on, and then the total magnetic force provided by electromagnets on all flap dams is controlled, so that multistage adjustment of flap dam water level control is realized.
If the analog quantity output module of the PLC is used for control, the higher-precision adjustment of the magnetic force of the electromagnet can be realized by adjusting the power supply voltage and current of the electromagnet. However, in consideration of the actual control precision requirement on site, high-precision adjustment of the attraction force of the electromagnet is not needed in general.
The dam opening water level is completely determined by the electromagnetic force, can be remotely and quickly adjusted, and is opened on the back surface and is not easy to be blocked by sundries. In addition, whether the flap dam is opened can be indirectly monitored by monitoring whether the magnetic device is opened.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are 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.
