Arc gate trunnion scour prevention structure suitable for high arch dam narrow slit outflow deep hole
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to an arc gate trunnion scour prevention structure suitable for a high arch dam narrow slit outflow deep hole, which comprises a deep hole upstream pressure section, a gate assembly and a downstream outlet section, and the gate assembly is arranged on the downstream outlet section and is attached to an outlet of the deep hole upstream pressure section; the gate assembly comprises a trunnion assembly and a radial gate, the outer arc surface of the radial gate is used for blocking the upstream pressure section of the deep hole, and the radial gate is fixedly connected with a trunnion girder arranged in the downstream outlet section through the trunnion assembly; the deep hole upstream pressure section, the gate assembly and the downstream outlet section are arranged, a high-speed nappe ejected from the deep hole outlet section is restrained through the downstream outlet section with a restraining function, a large amount of water is prevented from smashing a plunge pool bottom plate, and therefore the shore is prevented from being scoured; the water blocking block with the water blocking function is arranged on the upstream of the door supporting hinge, so that the situation that water fins impact the door supporting hinge, and safe operation of the radial gate is affected is avoided.
本发明涉及水利水电工程技术领域，具体涉及一种适用于高拱坝窄缝出流深孔的弧门支铰防冲结构，包括：深孔上游有压段、闸门组件和下游出口段，所述闸门组件设置在所述下游出口段，且与所述深孔上游有压段的出口贴合；所述闸门组件包括：支铰组件和弧形闸门，所述弧形闸门的外弧面用于封堵所述深孔上游有压段，所述弧形闸门通过支铰组件与设置在所述下游出口段内的支铰大梁固定连接；本发明通过设置深孔上游有压段、闸门组件和下游出口段，通过具有约束功能的下游出口段对从深孔出口段射出的高速水舌进行约束，避免大量水体砸向水垫塘底板，从而避免岸边被冲刷；通过在门支铰上游设置具有阻水功能的阻水块，避免水翅冲击门支铰，影响弧形闸门的安全运行。
