[0002] In water conservancy and hydropower projects, reservoirs exhibit water temperature stratification, which becomes more pronounced as the water level rises. Using surface water with lower turbidity can effectively improve the overall water quality of the reservoir and reduce subsequent water treatment costs. To meet the water quality requirements for both domestic and industrial use, newly constructed reservoirs often employ engineering measures to control the water intake area, and stratified water intake is one such method.

The output terminal of the control module 9 is connected to the gate assembly 2. The control module 9 controls the opening and closing of the gates in the gate assembly 2. The power supply module 7 is electrically connected to the gate assembly 2, the multispectral water quality sensor 3, the pressure level gauge 4, the control module 9, and the data transmission module 8. It should be noted that, in this embodiment, the multispectral water quality sensor 3 is a commercially available Yosemite Y4000 model, the pressure level gauge 4 is a commercially available HM21F model, and the control module 9 is a commercially available Modicon M241.

[0023] The vertical-tower tiered water intake tower 1 includes: at least three inlet channels of different heights, at least one outlet channel 18 lower than the inlet channels, and gate channels respectively connected to the outlet channels 18; each inlet channel is equipped with a multispectral water quality sensor 3 and a pressure level gauge 4; a gate assembly 2 is installed inside the gate channel; the gate assembly 2 is used to control the opening and closing of the inlet and outlet channels 18.

The pressure level gauge 4 accurately measures the reservoir water level data, and the sensor supports industrial-grade EMC level 3 standards, meeting the requirements for 24 / 7 unattended operation. It should be noted that in this embodiment, no specific limitations are imposed on the gate assembly 2, as long as it can control the opening and closing of the corresponding inlet or outlet channel 18 under the control of the control module 9.

[0024] In this embodiment, the height difference between the water inlet channels is 10~15m to cover water bodies with different water temperatures and turbidity levels.

[0025] Preferably, in this embodiment, the power supply module 7 includes a main power supply module 71 and a backup power supply module 72; the backup power supply module 72 includes an energy storage lithium battery 73 and an integrated photovoltaic panel 6, the output end of the integrated photovoltaic panel 6 is connected to the input end of the energy storage lithium battery 73, the output end of the energy storage lithium battery 73 is connected to one input end of the main power supply module 71; the other input end of the main power supply module 71 is connected to the power input line 10.

[0026] In this embodiment, an off-grid power supply system is constructed by integrating photovoltaic panels 6 and energy storage lithium batteries 73 at the top of the tower.

[0030] If no data exists that meets the water quality requirements lower than the collected water quality information, a message will be displayed indicating that there is no water quality that meets the water use requirements.

[0031] It should be understood that the control method of the control module 9 is simply to compare the water quality requirements with the collected water quality information, and then open or close the gate or issue a prompt according to the comparison result.
