An anti-icing water conservancy engineering gate

Abstract

The invention relates to an anti-icing hydraulic engineering gate. The anti-icing hydraulic engineering gate comprises a gate plate, a stand column, a power generation device arranged on a water opposing surface of the gate plate, a water storage device, and a circulating water pipe arranged on a water facing surface of the gate plate. Through improvement of all parts, the hydraulic gate realizes autonomous ice removal under the condition of basically needing no external energy, and can realize remote intelligent control.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering equipment, and in particular relates to an anti-icing water conservancy engineering gate. Background technique [0002] The most conventional component in large-scale water conservancy projects is the gate. Generally, multiple water conservancy gates in large-scale water conservancy projects are arranged side by side, and are controlled simultaneously or separately to realize the control of water flow. However, when the temperature is low, a large amount of ice will form on the upper part of the water conservancy gate, which not only greatly increases the weight of the gate, but also seriously affects the up and down movement of the gate. In the prior art, there are also some researches on the deicing of the gate, but basically, electric heating wires or other electric heating components are arranged on the surface of the gate to perform the ice melting operation. However, the materia...

However, the material of the general gate is alloy or alloy and concrete composite structure. When heated by electric heating components after being cooled, it will affect the stress distribution of the alloy material on the surface of the gate. After many times of alternating cold and heat, the gate will be The surface material has local stress concentration, resulting in local brittleness and cracks, which greatly reduces the life of the gate

However, if the method of maintaining the normal temperature of the gate surface is used to solve the freezing problem, a large amount of electric energy will be consumed, and it is difficult to power the gate, so it is more difficult to realize

[0003] Hydro-gate power generation has been a field of research concentration in recent years, but conventional sluice power generation is either water, wind and / or solar hybrid power generation, or pure hydropower generation, that is, it will inevitably use the kinetic energy of water flow, basically using The blades of the water wheel, while the height of the gate is often changed, the blades of the water wheel cannot keep half of the water surface and half of the water below the water surface at all times, so that the efficiency of the water wheel power generation is low, thus increasing the cost from another angle (using Low efficiency means less output, which reduces the benefit of the same infrastructure, that is, increases the cost)
