The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0027] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0028] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0029] There are many ways for water plants to get water, which can usually be determined by the type of water source and the geographical location. These methods include: 1) Artesian well water extraction: collecting underground water sources by drilling; the water plant will first conduct geological surveys to find a suitable water extraction site, and then drill a well, the depth of which ranges from tens of meters to hundreds of meters. This method of water extraction is widely used in areas with large water volume and good water quality. 2) River and lake water extraction: using water sources from surrounding rivers or lakes; the collected river water needs to be purified before it can be put into use. Since river water may contain more suspended matter, sediments and organisms, the purification process is more complicated. 3) Reservoir water extraction: The water quality of reservoir water is usually better because the water intake is located in the deep part of the reservoir. 4) Direct water diversion method: including digging water diversion channels, setting up sluices to control flow and water pressure, filtering and treating after introducing reservoir water, and transporting the purified water to the water plant.

[0030] 5) Pump station water diversion method: Build a pump station at the water diversion channel, install water pumps and control systems, and adjust the water flow and water pressure in real time. 6) Floating boat water intake: Use a movable rocker arm communication pipe to take water, and the water intake height can be adjusted automatically according to the water level. 7) Well water intake: The water intake pipe is buried deep underwater and taken from the center of the river, which is basically not affected by the water level. 8) Water well water intake: It is suitable for situations where the groundwater level is deep or the groundwater is seriously polluted, and groundwater is directly extracted through the groundwater well pipeline. The choice of these methods depends on the specific geographical and environmental conditions, as well as the quality and availability of water resources.
