The first embodiment is as follows:
referring to fig. 1 to 6, a dual-purpose water control device based on a telescopic gate plate, which is provided in an irrigation canal to regulate water flow, includes a gate frame 10 and a gate plate. Two sides of the gate frame are provided with gate slots 14, and two sides in the gate slots are provided with gate waterstops 15. The upper end of the gate frame is provided with a gate beam 16, and the gate beam is provided with a gate plate lifting machine 11.
In the present embodiment, the shutter includes a main shutter 20 and a weir plate 30.
The upper portion of main gate board is equipped with weir flow mouth 21, is equipped with weir plate groove 22 in the main gate board, and the both sides of weir flow mouth are equipped with weir plate guide slot 23, and weir plate inslot both sides on weir plate lower limb all are equipped with weir plate lower waterstop 24, and both sides in the weir plate guide slot are equipped with weir plate side waterstop 25, and the bottom of main gate board downstream side is equipped with the wash port 26 that communicates weir plate groove, and the wash port communicates with the bottom surface in weir plate groove, can discharge the water of infiltration weir plate inslot. The main gate plate is provided with a main gate plate upper beam 27 at the upper end of the weir flow port, the upper beam is of a detachable structure and is fixedly connected with the structures at two sides of the weir flow port during assembly.
The weir flashboard is a rectangle flashboard, and the height dimension L1 of weir flashboard is greater than the height L of main flashboard weir mouth, and the weir flashboard sets up the weir plate inslot in the main flashboard, and the both ends of weir flashboard and the cooperation of the weir plate guide slot of main flashboard are equipped with weir plate end seal block 32 between the both ends and the weir plate guide slot on the weir flashboard upper edge. Two faces of the weir gate are in contact with the lower waterstop of the weir plate and the lateral waterstop of the weir plate. The weir gate plate moves up and down in the weir plate groove and the weir plate guide groove, and the top edge 31 of the weir gate plate moves up and down in the weir flow opening of the main gate plate to form a water retaining weir with adjustable weir top height. The lowest position of the top edge of the weir gate plate is flush with the lower edge of the weir flow port of the main gate plate; the highest position of the top edge of the weir gate plate is contacted with the upper edge of the weir flow port of the main gate plate, namely contacted with the upper cross beam 27 of the main gate plate.
The main gate plate moves up and down along the gate groove 14, a gate water stop belt 15 is arranged in the gate groove, and two plate surfaces of the main gate plate are in contact with the gate water stop belt to prevent water from seeping through the main gate.
The gate elevating machine 11 drives the weir gate to rise. Various gate plate lifting machines can be adopted, including mechanical or manual operation machines such as a winch and a screw rod lifting device. In this embodiment, the gate lifter at the upper end of the gate frame uses a hoist to lift the weir gate by the weir gate cable 12. When the weir gate plate rises to the position of the upper beam 27 of the main gate plate (namely, when the weir gate plate is in contact with the upper beam), the weir gate plate starts to drive the main gate plate to rise, so that the bottom hole outflow function with adjustable gate opening is realized, and the pre-gate siltation which is possibly formed during the weir flow function is flushed. Under the combined action of the friction force and the gravity of the water stop, the main gate plate can keep still in a weir control working mode. In the gate operating mode, the main gate may be lowered as the weir gate is lowered. Under the combined action of the friction force and the gravity of the waterstop, the weir gate can descend along with the descending of the cable. The dual-purpose water quantity control device based on the telescopic gate plate is particularly suitable for water flow control of small channels.
The dual-purpose water quantity control equipment based on the telescopic gate plate can structurally meet a water flow control mode combined with a gate weir, and also has good sealing performance. The main gate plate has the same sealing performance and operation performance as the common gate plate valve. The weir flashboard moves in the frame of main flashboard, and the peripheral waterstop of main flashboard weir mouth and the sealed piece at weir flashboard both ends can realize effectively that main flashboard and weir flashboard are sealed between, and the drain hole of a small amount of infiltration weir plate groove also can be followed to the downstream side and discharged, can guarantee the operating function of weir flashboard.
Traditional gate can only realize the bottom outlet function of effusing, and the dual-purpose type water yield controlgear based on telescopic flashboard that this embodiment designed both can realize that the bottom outlet function of effusing also can realize the weir flow function, and the weir crest height can be adjusted moreover.
When the upstream water level and the downward discharge flow are required to be controlled and the flow is not too large, the weir flow operation mode is adopted. As shown in fig. 7, in the weir flow mode of operation: the main gate plate falls to the lowest position, the main gate plate is kept still, the weir gate plate moves up and down, and water flows through the upper edge of the weir gate plate in a top overflow mode. The adjustment of the height of the weir crest is realized by changing the height of the weir gate plate. The weir gate descends, the opening of the weir flow increases, and when the weir gate reaches the bottommost part, the weir flow reaches the maximum. Otherwise, the weir gate plate rises, the opening degree of the weir flow is reduced, and when the weir gate plate rises to the highest position, the weir flow working mode is completely closed, as shown in fig. 8. The control mode is suitable for the check gate on the irrigation channel, and when the flow is regulated, the variation amplitude of the water level is reduced as much as possible, and the upstream water level of the channel is stabilized.
In this embodiment, the main shutter is lifted by the weir shutter being moved, so that the structure and the operation equipment can be simplified. When only the downward discharge flow is required to be controlled or the flow is large, a bottom hole outflow working mode is adopted. As shown in fig. 9, in bottom hole outflow mode: the weir gate strip that rises to the top drives the main gate board and rises, and weir gate board upper end drives the entablature top of main gate board for main gate board and weir gate board form a whole, like a complete flashboard, main gate board and weir gate board upward movement simultaneously, the aperture of adjustment gate, the form that the rivers flowed with the bottom outlet passes through the gate. The bottom hole outflow working mode is suitable for a water distribution gate on an irrigation channel. This mode of operation can also be used when it is desired to remove silt deposits upstream of the main gate channel.
