[0024] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

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 a geological survey 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.

[0031] like Figure 1-3 As shown, for the water intake method of using fixed water intake structures for rivers or lakes, the embodiment of the present application provides a stratified water intake structure based on vacuum extraction, the stratified water intake structure includes a stratified water intake port 1, a water intake pipe 2, a vacuum extraction device 4 and an electrical device 5. Specifically, a first flap gate 11 and a second flap gate 12 are arranged at the water inlet of the stratified water intake port 1, the first flap gate 11 and the second flap gate 12 can open or close the stratified water intake port 1, and the height of the first flap gate 11 in the gravity direction is higher than the second flap gate 12; one end of the water intake pipe 2 is connected to the stratified water intake port 1, and the other end extends to the side of the mountain 3 away from the stratified water intake port 1; the vacuum extraction device 4 is installed on the mountain 3 and connected to the water intake pipe 2, the vacuum extraction device 4 is used for vacuuming the pipe section to form a siphon condition; the electrical device 5 is installed on the mountain 3, the electrical device 5 is electrically connected to the vacuum extraction device 4 and is used to supply power and control the opening and closing of the first flap gate 11, the second flap gate 12 and the vacuum extraction device 4.

[0032] The stratified water intake structure in the embodiment of the present application realizes siphon water intake of the water intake pipe 2 through the vacuum device 4, and the water intake method is more energy-saving; the first flap gate 11 and the second flap gate 12 can realize stratified water intake according to the water level changes of lakes and reservoirs, making the entire structure safer and more reliable. It should be noted that the distance between the first flap gate 11 and the second flap gate 12 and the flap gate size can be adjusted according to the local water level changes and water intake needs, and this article does not make specific restrictions on this.

[0033] like Figure 1-2 As shown, in a specific embodiment, the water intake pipeline 2 includes a first siphon section 21, a second siphon section 22, a downhill water inlet section 23 and a horizontal water inlet section 24 which are connected in sequence, the vacuum device 4 connects the second siphon section 22 and the downhill water inlet section 23, and the horizontal water inlet section 24 is provided with a maintenance valve, which is arranged in the valve well 6. In addition, the water intake pipeline 2 also includes a first water intake section 25 and a second water intake section 26 which are arranged in parallel, one end of the first water intake section 25 and the second water intake section 26 are respectively connected to the stratified water intake port 1, and the other end is connected to the first siphon section 21, and the first water intake section 25 and the second water intake section 26 are metal hoses.

[0034] like Figure 1-2 As shown, in a specific embodiment, a pier 7 is provided at one end of the first siphon section 21 away from the second siphon section 22, and the ends of the first water intake pipe section 25 and the second water intake pipe section 26 are fixedly connected to the pier 7, and the pier 7 can make the connection between the first siphon section 21 and the first water intake pipe section 25 / the second water intake pipe section 26 more stable and firm. A maintenance well 8 is provided at the highest point of the second siphon section 22, and the vacuum pumping device 4 is located in the maintenance well 8.

[0035] like Figure 1-2 As shown, in a specific embodiment, the stratified water intake structure further includes a buttress 9, and the number of buttresses 9 is multiple, and the multiple buttresses 9 are arranged at intervals in the second siphon section 22 and the downhill water intake section 23 along the extension direction of the water intake pipeline 2. The second siphon section 22 crosses the mountain 3 horizontally and is arranged obliquely upward at a preset slope, and the mountain 3 and the second siphon section 22 are backfilled and compacted by clay 10. The set anchor piers 7, buttresses 9 and other pillars can also make the entire pipe section system safe and firm, ensuring the service life of the stratified water intake structure.

[0036] It should be noted that, in the present embodiment, the number of piers 9 can be adjusted and preset according to the length of the uphill section and the downhill section of the mountain 3, that is, the actual length of the first siphon section 21 and the downhill water inlet pipe section 23.

[0038] Specifically, during the dry season, the water level of a lake or reservoir is low, the first flap gate 11 is closed, the second flap gate 12 is opened, and the vacuum device 4 is turned on, so that the first siphon section 21, the second siphon section 22, and the second water intake section 26 are internally vacuumed to form a siphon effect, and the raw water enters the stratified water intake 1 from the second flap gate 12, and then passes through the second water intake section 26, the first siphon section 21, the second siphon section 22, the downhill water inlet section 23, and the horizontal water inlet section 24 in turn, and finally enters the water plant for treatment.

[0039] During the rainy season or flood period, the water level in the lake or reservoir is high, the first flap gate 11 is opened, the second flap gate 12 is closed, and the vacuum device 4 is turned on to create a vacuum inside the first siphon section 21, the second siphon section 22, and the second water intake section 26, forming a siphon effect. The raw water enters the stratified water intake 1 from the first flap gate 11, and then passes through the second water intake section 26, the first siphon section 21, the second siphon section 22, the downhill water inlet section 23, and the horizontal water inlet section 24 in turn, and finally enters the water plant for treatment.
