[0001] The utility model relates to the technical field of deep - water - head arched cast - iron gates, and particularly relates to a deep - water - head arched cast - iron gate. Background Technique

[0002] The deep - water - head arched cast - iron gate is a control facility used to close and open the discharge (release) water channel, and is an important part of hydraulic structures. It can be used to intercept water flow, control water level, regulate flow rate, discharge sediment and floating objects, etc.

[0003] For example, a frame - type cast - iron gate for deep water heads with the authorization announcement number of "CN205999859U" includes a gate frame and a gate leaf. The gate frame includes two side edges, an upper support beam installed at the top of the gate frame, and a lower support beam installed at the bottom of the gate frame. The two side edges are inclined inward in the width direction of the gate towards the width direction of the gate, and the two side edges respectively extend out of the frame installation flange towards the outside in the width direction of the gate. By improving the form and structure of the frame and gate leaf of the cast - iron gate, the reliability and economy of the cast - iron gate are improved on the premise of meeting the existing production process. However, in the use of the deep - water - head arched cast - iron gate, the rear of the deep - water - head arched cast - iron gate is in the form of a plane or a depression, and the rear blocks the upper water level. Affected by the environment, such as strong wind weather, water waves will impact the rear of the deep - water - head arched cast - iron gate. At this time, the impact water waves will form bubbles, and the breaking of the bubbles will generate cavitation, which will damage the deep - water - head arched cast - iron gate for a long time. Moreover, the plane will form a unified pressure direction, resulting in the compression deformation of the deep - water - head arched cast - iron gate, reducing the protection performance of the deep - water - head arched cast - iron gate and shortening the service life of the deep - water - head arched cast - iron gate.
