Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0039] figure 1 It is a structural schematic diagram of an existing gravity lifting gate.

[0040] Existing dam break gates are mainly gravity lifting gates. Such as figure 1 As shown, a fixed pulley 2 is set above the gate 1, and a steel wire 3 passing through the fixed pulley 2 connects the weight 4 to the gate 1. Before the gate 1 is opened, the weight 4 is placed above the height of the gate 1; when the gate 1 is ...

Abstract

The invention discloses a lifting device for hydraulics simulation, which comprises a pillar, a lifting device and a switch device, wherein the pillar is used for supporting the lifting device; the lifting device is used for quickly lifting a gate through an elastic pull; and the switch device is used for controlling the lifting device to be stopped at a first stopping position and releasing the lifting device to enable the lifting device to lift the gate, and the first stopping position is corresponding to the elastic tensioning state of the lifting device and the closing state of the gate. Through an elastic device and pulleys, lifting power is provided for the gate, the initial gate lifting acceleration is large, the late acceleration is reduced gradually, time consumption for gate lifting is shortened, and operation safety is ensured.

Description

technical field [0001] The invention relates to the technical field of experimental theory, in particular to a lifting device for simulating hydraulic dam break waves. Background technique [0002] my country is the country with the largest number of reservoirs and dams today. After the reservoir is built, it can play the role of flood control, irrigation, water supply, power generation, etc., but it also brings certain potential risks. For example, once a reservoir dam breaks, the disasters caused to the vast downstream areas are often devastating. Dam break disasters are mainly caused by the impact and submersion of dam break floods. In particular, when a concrete structure dam fails, it can be approximately considered as an instantaneous failure, and the resulting dam failure flood is more typical and intense. Due to the suddenness and complexity of the dam failure problem, the current understanding of the dam failure is still immature. The physical model experiment of...
