Technical Field
The utility model relates to an adjustable weir equipment in flood control regulation field, in particular to hydraulic drive type adjustable weir.
Background
When the rainy season comes, the water level in urban flood control river channels and pipe ducts can continuously rise, and during rainstorm, waterlogging is caused by river water rising frequently. However, when dry seasons occur, the water level in the river channel is reduced due to long-term drought, and in severe cases, the water level in the river channel and the irrigation ditch is exhausted.
In order to ensure that sufficient water exists in a river channel or a pipe channel in dry seasons and waterlogging caused by river water rising is avoided in rainy seasons, the water conservancy facilities are required to be designed and built by considering equipment capable of being automatically opened and closed according to the water level.
The adjustable weir for impoundment is arranged in the urban flood control riverway and the pipe canal, and can automatically open and drain water when the river reaches the warning water level and automatically close the water retaining occasion when the river is lower than the warning water level. When the water level in the river channel or the pipe channel reaches the warning water level, the weir plate is turned downwards and opened under the action of water pressure. At this time, part of water in the river channel or the canal is discharged. When the water level in the river channel or the pipe channel is lowered to the warning water level, the weir plate is erected upwards, and the water flow in the river channel or the pipe channel is cut off.
The adjustable weir can ensure that the water level in the river channel is always high and the water level is not too high in rainy season, thereby avoiding waterlogging caused by river water rising.
However, the existing adjustable weir mostly adopts motor drive, so that not only is energy consumption high, but also manual management and control are needed, and then the later maintenance workload is large. Furthermore, installation is inconvenient in many environments due to the limitations involved with electricity usage.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A specific embodiment of the utility model is shown in fig. 1 and 2, be provided with the balancing weight protection casing 7 in the river course bilateral symmetry, be equipped with the balancing weight 6 in the balancing weight protection casing 7, and be fixed with a gravity drive wheel 5 through a drive wheel mount 51 on the upper portion of balancing weight protection casing 7.
An axle seat 8 is arranged at the upstream of the counterweight block protective cover 7. A rotating shaft 3 is arranged on the shaft seat 8; the two ends of the rotating shaft 3 are respectively provided with a weir plate driving grooved wheel 2, the rotating shaft 3 is provided with a weir plate 1, the bottom of the weir plate 1 is fixed on the rotating shaft 3, and the weir plate can rotate downwards along with the rotating shaft 3 under the driving of water pressure.
As shown in fig. 3, the slice driving sheave 2 is fan-shaped, and sheave cover plates 11 are installed at both ends of the slice 1, and the sheave cover plates 11 are pressed on the slice driving sheave 2. When the slice driving sheave 2 is subjected to a certain pressure, it can rotate about the rotary shaft.
In addition, still be equipped with a steel wire clamp 21 on weir plate drive sheave 2, wire rope 2's one end is fixed on steel wire clamp 21, and the other end is from penetrating in the balancing weight protection casing 7, and the rope body is connected with balancing weight 6 from the top around gravity drive wheel 5.
Wherein, be equipped with wire rope access & exit 71 on balancing weight protection casing 7, wire rope 4 passes through wire rope access & exit 71.
The working principle of the utility model is as follows:
when the high water level of upstream side reached the warning water level, the downward power of overturning that the river extrusion weir plate caused can't be overcome to balancing weight 6, and under hydraulic drive, weir plate 1 began to revolve around the axle center to oppress weir plate drive sheave 2, weir plate drive sheave 2 overcomes the gravity of balancing weight 6 and rotates together. After the weir plate 1 is opened, the flood control river or channel begins to drain.
When the water level drops to safe water level, the downward overturning force caused by the river water extruding the weir plate 1 is unlikely to overcome the upward pulling force provided by the counterweight block 6 to the weir plate 1 through the steel wire rope under the action of gravity. At the moment, the weir plate is turned upwards, and the flood control river or channel begins to store water.
