The water intake pool 1 is a closed structure, and a large-diameter pipeline 111 for surface water to enter is arranged on one side. A closed equipment control room 2 is arranged above the water intake pool 1, and the equipment control room 2 is made of reinforced concrete. A water delivery pipeline 3 is arranged in the equipment control room 2, one end of the water delivery pipeline 3 extends into the water intake pool 1 and is connected with a submersible pump 5, and the other end of the water delivery pipeline 3 extends to the outside of the equipment control room 2, and is connected with the water inlet pipe 72 of the machine well pipeline 7 through a pipe fitting; the submersible pump 5 is arranged at the inner bottom of the water intake pool 1 and is lower than the large-diameter pipeline 111. The water in the water intake pool 1 is pumped by the submersible pump 5 and sent to the water inlet pipe 72 of the machine well pipeline 7 through the water delivery pipeline 3, and then discharged through the water outlet pipe 73 of the machine well pipeline 7 for irrigation.

[0017] Specifically, if 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 on 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.

[0018] like Figure 2 , Figure 3 and Figure 5 As shown, the water delivery pipeline 3 includes a submersible pump outlet pipe 31, a check valve 32, an expansion joint 33, a water delivery valve 34 and a connecting pipe 35 which are connected in sequence. A through hole for the submersible pump outlet pipe 31 to pass through is provided on the cover plate 13 of the water intake pool 1. 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 water inlet pipe 72 of the machine well pipeline 7 through a pipe fitting.

[0019] like Figure 1-Figure 3 As shown, there are two through holes on the water intake pool cover plate 13, which can simultaneously meet the needs of two groups of water pipelines for water intake. A clamp-type fixing plate 311 is provided at the upper end of the submersible pump outlet pipe 31, and the clamp-type fixing plate 311 is against the cover plate 13.

When the water pipeline 3 has a problem and needs maintenance, the maintenance personnel can enter the equipment control room 2 through the inspection port 23.

[0021] An inspection port is provided on the cover plate 13 , and the inspection port is closed by a manhole cover 131 . When the submersible pump 5 has a problem and needs to be repaired, maintenance personnel can enter the water intake pool 1 through the inspection port on the cover plate 13 .

[0022] like Figure 4 As shown, a hoisting hole 21 and a light-collecting hole 22 are also provided at one end of the top of the equipment control room 2 away from the inspection port 23.

The movable steel plate 24 is usually closed. When the water intake device needs to be hoisted, the movable steel plate 24 on the hoisting hole 21 can be opened. Since the equipment control room 2 is a closed structure, when the water supply pipeline 3 needs to be inspected, the movable steel plate 24 on the light-collecting hole 22 can be opened.

[0023] like Figure 2 and Figure 3 As shown, a pressure transmitter 312 is provided on the submersible pump outlet pipe 31, and 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.

[0024] The connecting pipe 35 is provided with an exhaust valve 351 and a drain valve 352, through which the accumulated water in the water pipeline 3 and the irrigation outlet can be drained to prevent the water pipeline 3 and the irrigation outlet from being damaged by frost heave during winter use. When the accumulated water in the water pipeline 3 needs to be drained, the drain valve 352 is opened, and the accumulated water flows into the water intake pool 1 through the through hole on the cover plate 13.

[0025] like Figure 5As shown, the machine well pipeline 7 includes a machine well main pipe 71, one end of which extends into the machine well 6 and is connected to the machine well water pump, and the other end of the machine well main pipe 71 is provided with a three-way pipe 711, the three-way pipe 711 has a first interface, a second interface and a third interface that are interconnected, the first interface of the three-way pipe 711 is connected to the machine well main pipe 71, the second interface is connected to the water inlet pipe 72, and the third interface is connected to the water outlet pipe 73, and a check valve 712 is provided on the machine well main pipe 71, and the check valve 712 is installed upstream of the three-way pipe 711 to prevent the water in the water delivery pipeline 3 from flowing into the machine well 6 when the surface water in the water intake pool 1 is used for irrigation. A machine well valve 713 is provided on the machine well main pipe 71, and when the surface water in the water intake pool 1 is not supplied in time, the machine well valve 713 can be opened to extract the groundwater in the machine well 6 for irrigation through the machine well water pump.

[0026] A pair of clamp-type fixing plates are provided on the machine well main pipe 71, and the pair of clamp-type fixing plates are against the machine well 6 to make the machine well pipeline 7 more stable.

[0027] When in use, the water intake device is hoisted and buried. The buried water intake pool 1 is set under the ground. The top of the water intake pool cover 13 is about 1.1m below the ground, so that the backfill soil on the cover can meet the needs of most crops, and prevent the cover from being too low, and the water intake device is submerged when water comes from the pipeline. The equipment control room 2 is about 0.1m above the ground to prevent ground water from flowing into the equipment control room. A group of water delivery pipelines of the large-diameter pipeline water intake device is connected to the water inlet pipe of the machine well pipeline through pipe fittings, and another group of water delivery pipelines of the large-diameter pipeline water intake device is connected to the water inlet pipe of the machine well pipeline of another machine well through pipe fittings, so that two wells can be irrigated with surface water at the same time.

[0028] The large-diameter pipeline water intake device invented this time uses a large-diameter underground water pipeline and its supporting pumped well pipeline to replace the water source. The water conservancy facilities occupy less arable land, solving the problem of solving the land index problem when digging channels. When switching between surface water and groundwater for farmland irrigation, there is no need to install or disassemble the water pump. Farmland irrigation retains the original pumped well irrigation mode, which facilitates irrigation management for farmers.

[0029] The present invention combines a large-diameter pipeline water intake device with a pumped well to replace water sources without changing the original pumped well irrigation. It can irrigate with both surface water and groundwater, solving the problem of having only one water source for the same plot of land.

[0030] When the surface water in the water pool 1 is not supplied in time, the groundwater in the well 6 can be pumped out by the well pump for irrigation, which is convenient for farmers to irrigate.
