Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a sediment discharge system for a reservoir and the reservoir itself. Background Technology
[0002] A reservoir is an artificial lake formed by building a dam at the narrowest point of a mountain valley or river. It is a hydraulic engineering structure with multiple functions, including flood control, water storage, and runoff regulation. During its flow, a river carries a large amount of sediment due to the scouring and transporting action of the water. When this sediment flows into a reservoir, the sudden slowdown in water flow reduces the sediment's transport capacity, causing a large amount of sediment to deposit within the reservoir area. If the reservoir cannot regularly and promptly remove sediment, a series of serious problems will arise:
[0003] (1) Reduction in the effective storage capacity of the reservoir. As silt accumulates in the reservoir, it gradually occupies space, leading to a continuous reduction in the effective storage capacity. This reduces the reservoir's original designed water storage capacity, making it unable to store sufficient water and affecting its functions such as water supply, irrigation, and power generation. For example, for reservoirs used for agricultural irrigation, a reduced capacity may prevent them from providing sufficient irrigation water to farmland during dry seasons, impacting crop growth and yield.
[0004] (2) Reduced flood control capacity. Reservoirs play an important role in flood control by regulating and storing floodwaters. When the sediment flushing system is not working, sediment accumulation reduces the reservoir's flood control capacity. In the event of a major flood, the reservoir may not be able to hold enough floodwaters, leading to dangerous situations such as dam overflow.
[0005] (3) Impact on reservoir lifespan. The accumulation of large amounts of silt in a reservoir accelerates its aging and shortens its lifespan. Long-term siltation can also damage the reservoir's bottom structure, increasing the difficulty and cost of maintenance and repair. In severe cases, it may be necessary to prematurely decommission the reservoir and rebuild a new water conservancy project, resulting in significant economic losses.
[0006] (4) Impact on navigation. If the reservoir serves as a navigation channel, siltation will make the waterway shallower and narrower, affecting the normal passage of ships. Ships may run aground due to insufficient water depth, reducing the safety and efficiency of navigation, increasing transportation costs, and adversely affecting the transportation of goods in the region.
[0007] Current technologies generally employ mechanical sediment removal schemes for reservoirs, using mechanical equipment such as dredgers and suction pumps to directly remove accumulated sediment from within the reservoir. Dredgers remove sediment from the bottom of the reservoir and then transport it to a designated location via pipelines or other means; suction pumps use suction to lift and transport the sediment outside the reservoir. However, mechanical sediment removal schemes are not only inefficient but also have high labor costs.
[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0031] The following description, in conjunction with the accompanying drawings, details the reservoir sediment discharge system provided by this utility model through specific embodiments and application scenarios.
[0032] Figure 1 and Figure 2 The structure of a reservoir sediment discharge system 100 provided in Embodiment 1 of this utility model is shown. The sediment discharge system 100 includes at least one sediment discharge pipe 10 and at least one sediment discharge outlet 20 disposed on the reservoir's water body 200, with the sediment discharge pipe 10 and the sediment discharge outlet 20 interconnected. At least one sediment suction head 30 is provided on the sediment discharge pipe 10. The sediment suction head 30 mainly uses the natural pressure of water to suck up sand and water together from the reservoir's water body 200 and transports it outside the reservoir's water body 200 through the sediment discharge pipe 10 and the sediment discharge outlet 20.
[0033] Therefore, compared with the existing mechanical sand removal scheme, this utility model can automatically, conveniently and efficiently remove sand from the reservoir, and the implementation cost is low.
[0034] Preferably, the reservoir, located outside the water body 200 and below the sand discharge outlet 20, is equipped with an integrated filtration and transportation device 40, which includes a sand filtration unit 41 and a sand transportation unit 42, wherein:
[0035] The sand filtration unit 41 is used to filter sand from the excrement in the sand discharge pipe 10. Preferably, the sand filtration unit 41 is a filter screen. The excrement flowing out of the sand discharge pipe 10 usually includes mud and sand, so it is necessary to filter out the mud and retain only the sand. In comparison, mud particles have a small diameter, while sand particles have a large diameter, so the mud can be filtered out through the predetermined mesh of the filter screen, retaining the sand. The diameter of the predetermined mesh is larger than the diameter of the mud particles and smaller than the diameter of the sand particles.
[0036] The sand transport unit 42 is used to transport sand filtered through the sand filtration unit 41. Preferably, the sand transport unit 42 is a belt conveyor, with the filter screen mounted on the conveyor belt. The filter screen is moved to a predetermined position by rotating the conveyor belt. The predetermined position can be a transport transfer point.
[0037] In this way, the integrated filtration and transportation device 40 can filter sand from the excrement in the sand discharge pipe 10 and then transport it directly to the predetermined location, realizing the integrated operation of filtration and transportation and improving efficiency.
[0038] Preferably, the sand suction head 30 is equipped with a first booster water pump, which is used to assist in increasing the suction force of the sand suction head 30 and enhance the ability of the sand suction head 30 to absorb sand.
[0039] Preferably, the sand discharge pipe body 10 is provided with a second booster pump 50, which is used to assist in increasing the suction force of the sand discharge pipe body 10, thereby increasing the suction force of the sand suction head 30 and enhancing the ability of the sand suction head 30 to absorb sand.
[0040] In fact, this invention can also eliminate the need for the first booster pump and the second booster pump 50, and achieve the suction force of the sand suction head 30 simply through the water pressure difference.
[0041] Preferably, the sand discharge pipe body 10 includes multiple sub-pipe bodies, which are sequentially assembled to form the sand discharge pipe body 10. Therefore, the present invention can control the number of sub-pipe bodies according to actual needs, and different numbers of sub-pipe bodies assembled to form different sand discharge pipe bodies 10.
[0042] Preferably, the sand discharge pipe 10 is a flexible hose for easy operation.
[0043] Preferably, the sediment discharge system 100 further includes at least one drainage pipe 60 and at least one drainage outlet 70 disposed on the reservoir's water body 200, the drainage pipe 60 and the drainage outlet 70 being interconnected. The drainage pipe 60 and the drainage outlet 70 are used for drainage or flood discharge.
[0044] Figure 3This is a schematic diagram of a reservoir sediment discharge system provided in Embodiment 2 of this utility model. The sediment discharge system 100 includes multiple sediment discharge pipes 10 and multiple sediment discharge outlets 20, and the sediment discharge pipes 10 and sediment discharge outlets 20 are interconnected. More preferably, the sediment discharge system 100 also includes multiple drainage pipes 60 and multiple drainage outlets 70.
[0045] Figure 4 This is a schematic diagram of the reservoir sand removal system provided in Embodiment 3 of this utility model. The bottom and / or middle end of the sand removal pipe body 10 is provided with multiple corresponding sand suction heads 30 and multiple control valves 80. The control valves 80 are used to open and close the corresponding sand suction heads 30. In other words, the sand removal pipe body 10 of this utility model can precisely extract sand by opening the corresponding sand suction head 30 at a specific location through the control valve 80.
[0046] This utility model also includes, as follows: Figures 1-4 The reservoir of any of the sand discharge systems 100 includes a reservoir body 200, on which a sand discharge pipe 10 and a sand discharge outlet 20 are provided.
[0047] In summary, the reservoir sediment discharge system of this invention includes a sediment discharge pipe and a sediment discharge outlet installed on the reservoir's water body, the two being interconnected. The sediment discharge pipe is equipped with at least one suction head, which uses natural water pressure to draw up sand and water from the reservoir's water body and transport it outside the water body through the discharge pipe and outlet. Therefore, this invention enables automatic, convenient, and efficient sediment discharge from the reservoir at a low cost.
