Automatic storage and discharge device for dam

Abstract

The invention discloses an automatic storage and discharge device for a dam. The automatic storage and discharge device comprises a plurality of dam piers which are arranged on the top surface of the dam; storage and discharge plates which are perpendicular to the top surface of the dam when standing still are arranged among the dam piers; the tops of the storage and discharge plates are articulated with the dam piers; a plate returning device is connected between the storage and discharge plates and the dam; the dam piers are layered in the vertical direction; the storage and discharge plates are connected among all layers of dam piers; when the water flow is normal, the storage and discharge plates are in the standing state and perpendicular to the top surface of the dam under the joint action of the plate returning device and a safety pin to ensure the slow water storage work in the dam; and when the flood peak arrives and the water level exceeds the warning state, the powerful impact must greatly exceeds the bearing capacity of the plate returning device and the safety pin, thus the storage and discharge plates can be naturally opened under the water pressure to realize the automatic discharge of the flood peak. Since multiple layers of storage and discharge devices are arranged, the automatic storage and discharge device is suitable for various large, medium and small reservoirs and can ensure safe and efficient flood discharge.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to an automatic storage and discharge device suitable for dam bodies such as reservoirs, lakes, small dams of big ponds and the like. Background technique [0002] At present, there are large, medium and large water reservoirs, lake dams and Datang dams across the country, because when the rainy season comes every year, sudden rainstorms or extremely heavy rains occur from time to time, especially in the "clouds" at higher altitudes. , "Gui" and "Sichuan" areas and general mountainous and hilly areas, once the flood comes, its impact force will be as large as hundreds of tons, dozens of tons or more than ten tons. If there is no automatic storage and discharge device on the dam foundation, the dam foundation will The water storage capacity in the area has increased sharply, and the impact and pressure of the flood are increasing, and its dam foundation must be unbearable...

AI Technical Summary

Problems solved by technology

However, when carrying out the actual simulation application of this utility model, the applicant found that especially for a large amount of flood storage and discharge of large and medium-sized reservoirs, due to the high pressure brought by the rapidity of the flood peak, the common single-layer storage and discharge plate also produces a great threat to stability
