Description

Technical Field

[0001] The invention belongs to the technical field of water intake devices and relates to a variable-elevation water intake device that is adaptive to complex reservoir environments. Background Art

[0002] Water transfer projects in cold regions often face the impact of ice during winter water delivery. In regions with relatively cold climates, water can be delivered under ice sheets. However, in less cold regions, such as the North my country Plain, stable ice sheets are often difficult to form in winter. Once the ice sheet breaks, large amounts of ice are carried downstream with the water flow, increasing the pressure of downstream ice delivery. Ice can often stagnate, sink, and accumulate at locations with varying cross-sections, slopes, and water-related structures (gates, bridges), forming ice jams or ice dams. These ice jams block water flow and reduce its flow capacity, potentially triggering ice floods and other disasters such as river overflows, seriously threatening people's lives and property.

[0003] In order to solve the problem of water supply during the ice period in the above-mentioned less cold areas, if high-temperature water can be injected into the water supply channel from the reservoir, the amount of ice produced can be controlled and ice-free water supply can be achieved in winter. On the one hand, the occurrence of ice jams and ice dams can be fundamentally avoided. On the other hand, the water supply capacity of the project can be fully utilized. The ice-free water supply flow rate is nearly twice that of water supply under the ice sheet.

[0004] In reservoirs with large storage capacity, the water temperature in the reservoir forms a vertical distribution with high surface temperature and low bottom temperature. The existing reservoir water intake is fixed and cannot be flexibly adjusted according to changes in seasons, water levels, etc., and cannot guarantee that water with suitable temperature can be obtained when needed.

The height of the water intake pipe body 8 is adjusted according to the water level. After it reaches the appropriate position, the water intake pipe body 8 is connected to the water outlet trough 21 at the corresponding position, and the corresponding valve assembly is opened by activating the unit to realize variable height water intake.
