Description
Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to a gate with a water passing channel.
Background
The construction of the gate generates a physical separation effect on the upstream and downstream river sections of the river channel, so that the originally smooth water flow is artificially separated, on one hand, the separation of the gate enables the upstream and downstream of the river to form a water level drop, and when the upstream water level of the gate overflows, as the water falling height is larger, larger noise is easily generated, and the normal rest of surrounding residents is influenced; on the other hand, as the river continuum is damaged, most of fishes freely move in upstream and downstream riverways according to natural habits for the reasons of foraging, breeding, overwintering and the like for the fishes, after a gate is built, the fishes cannot freely move across the gate due to the objective factor of blocking the riverway by the gate, the fishes are prevented from swimming back to a spawning ground at the upstream of a reservoir to spawn, and part of the fishes are prevented from returning to the sea, which has serious influence on the growth and breeding of the fishes, wherein the influence on the migratory and semi-migratory fishes is the largest.
In the prior art, technical personnel provide solutions for the above defects, but the solutions are only provided for one of the defects without exception, for example, for the noise generated by the water passing through the gate, the prior art proposes to build an overflow dam overflow on the gate or add curtain cloth on a landscape waterfall to improve the flow state of the water flow so as to reduce the noise; aiming at the problem that fishes cannot migrate, the prior art proposes to adopt forms of a fish lock, a fish elevator, a fish collecting boat and the like to help the fishes to arrive at a spawning or breeding place. The defects of the prior art are obvious, firstly, any one of the schemes can realize either the noise reduction function or the fish passing function, and the noise reduction function and the fish passing function cannot be both realized, so that the material resources are greatly wasted; secondly, the noise reduction schemes mentioned in the prior art are only limited in amplitude reduction and large in engineering investment, and the fish passing facilities in the above forms have many defects such as easy reduction of fish migration performance, low fish passing efficiency, difficult management and operation, high energy consumption and the like no matter how different structures exist in the fish passing schemes.
In addition, the conventional gate often has problems such as water leakage and trouble during use, and the cause of the problems is caused by the vibration of the gate. The cause of gate vibration is complicated, but it is generally considered that the instability of the flowing water action is a direct cause of the gate vibration problem. In the process of opening or closing the gate, the generation of flowing water can be given, when the flowing water contacts the gate, certain acting force can be given to the gate, the vibration of the gate is caused, however, in most cases, the vibration is weak, but under certain special conditions, for example, when the pulsation frequency of water flow is close to or equal to the natural vibration frequency of the gate, the gate can cause very violent vibration due to resonance, and the safety of the gate is seriously threatened.
