Description
Technical Field
The utility model belongs to the technical field of soil and water conservation, specifically speaking relates to a reservoir hydro-fluctuation belt wave loses monitoring devices.
Background
The water level of the reservoir is seasonal fluctuation, and the land of the reservoir is periodically submerged and exposed to the water surface. The hydro-fluctuation belt is affected by the alternation of dry and wet caused by the water storage of the power station, the ground vegetation is damaged, the soil structure is changed, and obvious vulnerability is shown on the stability of an ecological system, the external interference resistance and the adaptability to the change of the ecological environment. A waste slag field formed by water and electricity development and a cliff broken stone bank slope formed by an excavation slope, a section and the like are partially positioned in a water-level-fluctuating zone after water is stored in a reservoir, and after the water level of the reservoir rises, the reservoir is exposed to the land, usually in hot and humid weather, heavy rain and heavy rain frequently occur, and the reservoir becomes a zone with serious soil erosion under the combined action of water surface waves and surface runoff scouring.
Wave erosion, also called wave erosion, runs through the whole water level fluctuation cycle of a reservoir area and is widely distributed on land and water interfaces with different water levels. The slope surface near the waterline has wave erosion with different degrees, particularly on the slope surface of a steep slope, a beach slope and a gentle dry land of a soil property hydro-fluctuation belt. The destructive effect of waves on the reservoir bank mainly comprises the following aspects: (1) the waves slap the bank slope to loosen the rock and soil mass of the bank slope and even be rolled away by the waves; (2) waves scour soil particles in rock-soil bodies to loosen and destabilize bank slope rock-soil; (3) the water is poured into gaps of the rock-soil body under the action of surge, the retained water generates a jacking action at the bottom of the rock-soil body after waves are removed, the rock-soil body is loosened and slides down, and meanwhile, the water poured into the gaps of the rock-soil body soaks the rock-soil body, so that the slope stability is reduced. Wave erosion includes wave erosion, the transport action of waves and shoreside currents; the one-time damage caused by the method is small, but the space-time distribution of the action is wide, and necessary near-empty conditions can be provided for the bank slope to retreat. The waves erode the soil of the hydro-fluctuation belt, so that the soil quality is reduced, the restoration of hydro-fluctuation vegetation is influenced, the ecological service functions of sand blocking and dirt interception are destroyed, and the continuous retreat of the reservoir bank and the instability of the reservoir bank are easily caused.
The problems of vulnerability of hydro-fluctuation belt ecosystems and soil erosion of hydro-fluctuation belts are concerned by all parties, but the monitoring means are deficient. At present, most of the monitoring of the soil erosion in the erosion zone focuses on monitoring of rainfall erosion, the wave erosion in a reservoir area is less considered, and a technique and a method for monitoring the wave erosion in the erosion zone are lacked. By monitoring the turbidity of the water body, the wave pressure intensity and the change of the slope form, the wave erosion intensity of the hydro-fluctuation belt is calculated, and the technical device and the monitoring method for monitoring the wave erosion of the hydro-fluctuation belt are provided, so that scientific and technological support can be provided for maintaining the stability of the reservoir bank and relieving the sediment accumulation of the reservoir.

The method realizes high accuracy of field soil erosion monitoring, can automatically judge and calculate, is only suitable for monitoring the rainwater runoff erosion soil, and is not suitable for monitoring the wave erosion soil.
According to the coastal erosion monitoring pile (application number: 201820104114.4, application date: 2018-01-22), the monitoring pile is vertically fixed below the coast, the upper part of the monitoring pile protrudes above the coast, and a surveying and mapping instrument can be directly fixed on the top of the monitoring pile, so that the height of the monitoring pile can be measured, the measurement precision is high, the error is small, and the measurement process is more convenient. However, the monitoring device has single function, can only determine the erosion degree by measuring the height, and has high cost, time and labor consumption and complex construction process.
The patent relates to a water quality turbidity monitoring device (application number: 201521082597.5, application date: 2015-12-23), which is simple to operate, does not need to collect samples to monitor the water quality turbidity, and can be directly arranged in a water pipe to monitor the turbidity of water by recording and collecting the light intensity change of water in a permeation water pipe. However, the device has a single function, is only suitable for monitoring the water quality turbidity of one-way water flow in the water pipe, and is not suitable for monitoring the water quality turbidity of the reservoir area.
The microwave wave buoy body device described in Liu Shi Hemerocallis et al (Liu Shi Hemerocallis, Qiyong, Liu Haifeng, microwave wave buoy monitoring system [ J ]. proceedings of oceanographic technology, 2011.02.013) has the characteristics of high stability, high light transmittance, high ultraviolet resistance and the like, but the device cannot monitor the wave intensity in a specific direction.
