Anti-surge device for water and soil conservation of hydro-fluctuation belt

Abstract

The invention discloses an anti-surge device for water and soil conservation of a hydro-fluctuation belt, and belongs to the technical field of anti-surge devices. The anti-surge device is characterized in that the bottoms of the two sides of an operation box are provided with connecting plate position fixing assemblies, one side of a protective net connecting assembly is provided with a connecting positioning assembly, after positioning, a worker lays a first protective net, a second protective net and a third protective net on a bank slope to protect water and soil, after laying is completed, the worker enables positioning nails to penetrate through positioning holes to be connected and positioned with the bank slope, wave water enters through water inlet holes after mounting, a wear-resisting and pressure-resisting air bag rises along with continuous increase of water pressure, and in the lifting process, a second wave-proof plate, a third wave-proof plate and a fourth wave-proof plate are driven to move upwards, so that flexible wave resistance is achieved, the height can be automatically adjusted according to the size of wave water, the device is extremely convenient to mount and good in wave-proof effect, connection and positioning are conducted through clamping pieces and connecting sheets, and the angle can be adjusted while mounting is facilitated.

Description

technical field [0001] The invention relates to an anti-surge device, in particular to an anti-surge device for water and soil conservation in the ebb and flow zone, and belongs to the technical field of anti-surge devices. Background technique [0002] The so-called anti-surge device refers to a kind of net product that preserves and protects the soil and water on hillsides. It originates from the rapid development of hydropower station construction, and the impoundment of reservoirs has caused serious soil erosion in the ebb and flow zone of the reservoir area. The speed, frequency, wind speed, and the surge caused by the periodic fluctuation of water level, the Yangtze River channel is a famous "golden waterway". It is reported that after the Three Gorges Project is fully put into operation, the volume of ships with a tonnage greater than 5t in the reservoir area will reach 300 times / day , the high frequency of surges scours the bank slope, the periodic fluctuation of the...

[0002] The so-called anti-surge device refers to a net product that protects the water and soil on the hillside. It originates from the rapid development of hydropower station construction. The water storage of the reservoir causes serious water and soil loss in the ebb and flow zone of the reservoir area. The main reason is the tonnage of the ship, Speed, frequency, wind speed, and surge erosion caused by periodic water level fluctuations. The Yangtze River waterway is a famous "golden waterway". It is reported that after the Three Gorges Project is fully put into operation, the volume of ships with a tonnage greater than 5 tons in the reservoir area will reach 300 times per day. , the high frequency of surges scours the bank slope, the periodic fluctuation of the water level of the reservoir and the swell generated by the boat have a significant scouring effect on the bank slope in the ebbing zone, the vegetation growth soil in the ebbing zone is washed away by the water body, and the basic conditions for plant growth are constantly changing. Weakened, resulting in serious water and soil erosion in the water-fluctuating zone, destroying the ecosystem of the reservoir area, resulting in a serious uncoordinated landscape, and also increasing the risk of geological disasters and reservoir sedimentation and other problems

[0003] The existing anti-surge device assembly method is relatively simple, only can provide a single performance, can not play a role in complete protection, the protection structure of the anti-surge device is less, resulting in a short service life of the anti-surge device Protection is carried out according to the size of the surge. Most of the existing surge protection devices are integrated, which will lead to problems such as inconvenient installation.
