The present application belongs to the technical field of water conservancy and hydropower engineering closure construction, and particularly relates to a kind of embankment closure method based on integral assembly type double ridge closure bottom protection structure.The present application precast and accurately throw the integral bottom protection structure formed by rigid connection of bottom protection section and double ridge section in dry season of a year before closure, with standardized reinforced gabion as basic unit, adopt double connection inside and outside to form continuous plate type whole, with high impact resistance and stone blocking foot capacity.Through particle size and impact distance calculation, throw test, GPS joint positioning to realize accurate underwater throwing.After bottom protection construction is completed, embankment pre-advance is implemented in dry season of next year, and large stone and reinforced gabion are continuously thrown in closure stage, which can improve the stability of throwing material, prevent embankment collapse, and realize safe and rapid closure.The present application can solve the problems of traditional dispersed bottom protection, such as easy loss, low precision, interference with flood discharge, etc., and greatly improve the safety and efficiency of closure under complex riverbed conditions.

The utility model relates to the technical field of building energy conservation and control, in particular to a control device of a rural solar energy-air source heat pump coupling hot air type heat storage ground. During use, according to different time periods, the control temperatures of the solar heat collection temperature sensor, the water temperature sensor and the indoor air temperature sensor and the start-stop time of the solar heat collection pump, the hot water pump and the circulating water pump are set, and the temperature controller and the time controller are used for controlling operation of the solar heat collection pump, the hot water pump and the circulating water pump in a two-stage mode. According to different heat loads needed in different time periods, automatic operation and two-stage heat supply are achieved, the problems that a water pump or equipment is frequently started and stopped due to fixed temperature control, the solar heat collection effect is poor, the heat supply amount is not matched with the heat load requirement of a resident, heat is wasted and the like are solved, normal operation of the system is guaranteed, and electric energy consumption or operation cost is reduced. The solar energy assurance rate is improved, the frequent starting condition of the system is reduced, and the matching degree of the heat supply amount and the heat load requirement of residents is improved.

This invention provides a method and system for intelligent gate control of groundwater-river / lake ecological water levels. The method includes: acquiring target data collected in real time through a sensing layer; the target data includes surface water level and flow data, groundwater level data, and meteorological data; using a coupled hydrological model in the decision layer, based on the target data, rolling predictions of the state changes of surface water and groundwater under different gate opening scenarios within a future set time period; based on the predicted state changes and preset ecological control targets, optimization calculations are performed through an intelligent control algorithm in the decision layer to generate an optimal gate opening command; the optimal gate opening command is sent to the execution layer to drive the gate to adjust to the target opening, and the actual gate opening is obtained for feedback. In this method, the rolling optimization of gate opening through a coupled hydrological model and intelligent algorithm improves the ecological flow guarantee rate and effectively enhances the ecological protection level and system adaptability.

This invention provides an eco-hydraulic channel device and its usage method that are adaptive to water and sediment rhythms. The aim is to regulate sediment deposition in lakeside wetlands, ensure ecological water use, improve water quality, and restore the ecosystem by constructing a channel device and intelligent management system adapted to the hydrological rhythms of lakes. The device includes an inlet section (containing a narrow / deep / shallow-wide cross-section and permeable dikes), an ecological overflow section (divided into shallow habitat zones, surface flow purification zones, and deep pool conservation zones), a sediment interception system (prefabricated triangular cones and sedimentation tanks), and an intelligent management unit (water quality monitoring, water level sensing, and automated control modules). This invention can significantly improve the ecological water level guarantee rate of lakeside wetlands, reduce sediment deposition, enhance the self-purification capacity of water bodies, enrich biodiversity, and is suitable for lake ecological restoration projects.
