The invention discloses a flood-prevention and drought-prevention water conservancy gate capable of automatically controlling flow. The water conservancy gate comprises a control valve box, a pressuredetection device is arranged on the left side of the control valve box, the pressure detection device comprises a water pressure detection box fixedly arranged on the left side of the control valve box, and a water pressure detection cavity with an upward opening is formed in the water pressure detection box. An air bag box is arranged in the water pressure detection cavity, an air bag cavity isformed in the air bag box, a control valve cavity is formed in the control valve box, and a flow control device is arranged in the control valve cavity. The water conservancy gate is suitable for being used in a small river riverway and is a device used for controlling the water flow speed, the upstream water line is detected by detecting the upstream water pressure, when the water line is too high, water is drained to the downstream portion, when the downstream water flow is too fast, a valve is closed, the water flow speed is reduced, the situation that too much water is stored in the upstream portion is prevented, and the situation that flood is caused due to the fact too large water flow exists in the downstream portion is avoided.
本发明公开的一种防洪防旱的可自动控流水利闸门，包括控阀箱，所述控阀箱左侧设有测压装置，所述测压装置包括位于所述控阀箱左侧固定设有的水压检测箱，所述水压检测箱内设有开口向上的水压检测腔，所述水压检测腔内设有气囊箱，所述气囊箱内设有气囊腔，所述控阀箱内设有控阀腔，所述控阀腔内设有控流装置，本发明适用于较小河流河道内，是用于控制水流流速的装置，本发明通过检测上游水压大小来检测上流水位线，水位线过高时向下游泄水，当下游水流过快时，关闭阀门，减小水流流速，防止上游存水过多，下流不会因为水流过大而导致洪水。
