[0020] To better understand the purpose, function, and specific design scheme of this utility model, the large-diameter pipeline water intake device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1-5 As shown, the large-diameter pipeline water intake device of this utility model includes a water intake pool 1, which is made of reinforced concrete and has a closed structure. A large-diameter pipeline 111 for surface water to enter is provided on one side. A closed equipment control room 2 is provided above the water intake pool 1. The equipment control room 2 is made of reinforced concrete and has a water supply pipeline 3. One end of the water supply pipeline 3 extends into the water intake pool 1 and is connected to a submersible pump 5. The other end of the water supply pipeline 3 extends to the outside of the equipment control room 2 and is connected to the inlet pipe 72 of the well pipeline 7 through a fitting. The submersible pump 5 is located at the bottom of the water intake pool 1 and is lower than the large-diameter pipeline 111. The submersible pump 5 draws water from the water intake pool 1 and sends it through the water supply pipeline 3 to the inlet pipe 72 of the well pipeline 7. The water is then discharged through the outlet pipe 73 of the well pipeline 7 for irrigation.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, the water intake pool 1 includes a pool body 11, a base 12 is provided at the bottom of the pool body 11, and a cover plate 13 is provided at the top of the pool body to form a closed inner cavity. A large-diameter pipe 111 is connected to the closed inner cavity, and surface water enters the water intake pool 1 through the large-diameter pipe 111.

[0023] like Figure 2 , Figure 3 and Figure 5As shown, the water supply pipeline 3 includes a submersible pump outlet pipe 31, a check valve 32, an expansion joint 33, a water supply valve 34, and a connecting pipe 35 connected in sequence. The cover plate 13 of the water intake pool 1 is provided with a through hole for the submersible pump outlet pipe 31 to pass through. One end of the submersible pump outlet pipe 31 passes through the through hole and is connected to the output end of the submersible pump 5. One end of the connecting pipe 35 extends out of the equipment control room 2 and is connected to the inlet pipe 72 of the well pipeline 7 through a fitting.

[0024] like Figures 1-3 As shown, the water intake tank cover plate 13 has two through holes, which can simultaneously meet the water intake needs of two sets of water supply pipelines. The upper end of the submersible pump outlet pipe 31 is provided with a clamp-type fixing plate 311, which abuts against the cover plate 13. The clamp-type fixing plate 311 can make the water supply pipeline 3 more stably fixed in the equipment control room 2.

[0025] like Figures 2-4 As shown, the submersible pump 5 is equipped with a filter screen, which filters impurities in the surface water to prevent them from entering the submersible pump outlet pipe 31. The submersible pump 5 is connected to the power control cabinet 4 via a power cord. The power control cabinet 4 is installed on the top of the equipment control room 2. The top of the equipment control room 2 is also equipped with an inspection port 23, which is closed by a manhole cover 231. When the water pipeline 3 has a problem and needs maintenance, maintenance personnel can enter the equipment control room 2 through the inspection port 23.

[0026] An inspection port is provided on the cover plate 13, which is closed by the well cover 131. When the submersible pump 5 has a problem and needs to be repaired, the maintenance personnel can enter the water intake pool 1 through the inspection port on the cover plate 13.

[0027] like Figure 4 As shown, the top of the equipment control chamber 2, away from the inspection port 23, is also equipped with a hoisting hole 21 and a light-transmitting hole 22. There are two hoisting holes 21, through which the water intake device can be hoisted. Both the hoisting hole 21 and the light-transmitting hole 22 extend above the top surface of the equipment control chamber 2, and are enclosed by a movable steel plate 24. The movable steel plate 24 is normally closed, but can be opened when the water intake device needs to be hoisted. Since the equipment control chamber 2 is a closed structure, the movable steel plate 24 on the light-transmitting hole 22 can be opened when the water pipeline 3 needs to be inspected.

[0028] like Figure 2 and Figure 3 As shown, a pressure transmitter 312 is installed on the submersible pump outlet pipe 31. The pressure transmitter 312 is electrically connected to the power control cabinet 4. The water pressure in the submersible pump outlet pipe 31 can be obtained through the pressure transmitter 312, and the obtained pressure value is transmitted to the power control cabinet 4.

[0029] The connecting pipe 35 is equipped with an air vent valve 351 and a drain valve 352. The drain valve 352 can be used to drain the water accumulated in the water supply pipeline 3 and the irrigation outlet to prevent the water supply pipeline 3 and the irrigation outlet from freezing and swelling during winter use. When it is necessary to drain the water accumulated in the water supply pipeline 3, the drain valve 352 is opened, and the water will flow into the water intake pool 1 through the through hole on the cover plate 13.

[0030] like Figure 5 As shown, the well pipeline 7 includes a main well pipe 71, one end of which extends into the well 6 and is connected to the well water pump. The other end of the main well pipe 71 is equipped with a tee pipe 711, which has three interconnected interfaces: a first interface, a second interface, and a third interface. The first interface of the tee pipe 711 connects to the main well pipe 71, the second interface connects to the inlet pipe 72, and the third interface connects to the outlet pipe 73. A check valve 712 is installed on the main well pipe 71, upstream of the tee pipe 711, to prevent water from the water supply pipeline 3 from flowing into the well 6 when using surface water from the water intake pool 1 for irrigation. A well valve 713 is installed on the main well pipe 71. When the surface water supply from the water intake pool 1 is insufficient, the well valve 713 can be opened to allow the well water pump to draw groundwater from the well 6 for irrigation.

[0031] A clamp-type fixing plate is installed on the main well pipe 71, which abuts against the well 6 to make the well pipeline 7 more stable.

[0032] In use, the water intake device is hoisted and buried. The buried water intake pool 1 is located underground, with the top of the water intake pool cover plate 13 about 1.1m below the ground level. This ensures that the backfill soil on the cover plate can meet the needs of most crops while preventing the cover plate from being too low and submerging the water intake device when water comes in from the pipeline. The equipment control room 2 is about 0.1m above the ground level to prevent surface water from flowing into the equipment control room. One set of water supply pipelines of the large-diameter pipeline water intake device is connected to the inlet pipe of the well pipeline through fittings. The other set of water supply pipelines of the large-diameter pipeline water intake device is connected to the inlet pipe of the well pipeline of another well through fittings, allowing both wells to use surface water for irrigation simultaneously.

[0033] This invention relates to a large-diameter pipeline water intake device that uses a large-diameter underground water transmission pipeline and its associated well pipeline for water source replacement. This method minimizes the land occupation of the irrigation facilities and solves the problem of land quota issues associated with canal excavation. When switching between surface water and groundwater sources for farmland irrigation, there is no need to install or dismantle water pumps, allowing farmland irrigation to retain the original well irrigation method and facilitating irrigation management for farmers.

[0034] This invention combines a large-diameter pipe water intake device with a well to replace the water source without changing the original well irrigation method. It can use both surface water and groundwater for irrigation, thus solving the problem of only one water source for the same plot of land.

[0035] When the surface water supply in water intake pool 1 is insufficient, groundwater in well 6 can be pumped out for irrigation, which facilitates irrigation for farmers.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
