Transmission type sluice turning apparatus

Abstract

The invention discloses a drive-typed turning strobe device which relates to a strobe device that quickly and fully blocks water current in a flow channel or adjusts the excess flow rate. The device is composed of a rotatable strobe which is installed in the flow channel, a transmission component arranged at one end of the strobe and a power plant thereof, or a power plant arranged at one of the strobe and a transmission component thereof. The device not only has simple and reasonable structure as well as safe and reliable working performance, but also convenient and simple production, installation and maintenance. Furthermore, the device can also adapt to various large excess flow channels.

Description

Technical field [0001] The invention relates to a transmission-type reversing gate device for quickly and completely cutting off water flow or regulating its overflow flow in a flow channel. Background technique [0002] At present, the devices used to block or adjust the flow in the pressurized flow path (that is, the closed flow path) mainly include butterfly valves, valves, etc.; in the non-pressure flow path (that is, the open flow path) The devices used to cut off or adjust the flow passage mainly include plane gates, arc gates and siphon chambers. And there is also an overturning gate that automatically opens and closes around the support hinge. The shortcomings of the above gate devices are: the butterfly valve composed of a cylindrical shell, a disc-shaped valve leaf and a valve leaf shaft that passes through the valve leaf and passes through the cylindrical shell and is connected to the operating mechanism. When the valve composed of shell, door leaf, door leaf gr...

AI Technical Summary

Problems solved by technology

The shortcomings of the above gate devices are: the butterfly valve composed of a cylindrical shell, a disc-shaped valve leaf and a valve leaf shaft that passes through the valve leaf and passes through the cylindrical shell and is connected to the operating mechanism. When the valve composed of shell, door leaf, door leaf groove and operating mechanism is used in a flow channel with a large flow area, the shell, valve leaf or door leaf is difficult to cast and turn.

Moreover, the door leaf groove will cause a large local loss to the water flow

The plane gate installed in the gate slot cannot be removed when freezing or foreign matter jams in the gate slot, making it impossible to open and close, and requires a huge opening and closing device

The curved gate supported by the supporting hinge has a huge structure, is difficult to manufacture, and requires high installation requirements.

The siphon chamber structure works by the siphon principle, although the water breaks off quickly and there is no leakage, but because of its huge structure, it takes a long time to pump out the air in the siphon chamber, so it is difficult to implement in a large flow channel

The automatic overturning gate supported by the hinge and automatically opened and closed by the water pressure difference not only has poor working reliability, but also the pier on which the hinge is installed seriously affects the flow capacity of the water flow, so it is not widely used
