Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and more particularly to a water conservancy irrigation system and method based on a pump station. Background Art

[0002] After years of construction, my country's agricultural irrigation and drainage systems and other infrastructure have reached a certain scale, with small pump stations being the main ones. In farmland irrigation and drainage, small and medium-sized water pumps play a vital role. However, traditional pump stations occupy a large area and have a long construction period. The functions of pump station equipment gradually weaken in long-term work, and parts age rapidly, affecting the economic benefits of farmland. Under the current situation of vigorous development of agriculture, agricultural modernization is of great significance to the optimal configuration of water conservancy equipment, especially the management and supervision of water conservancy equipment resources during operation, as well as the rapid development of agriculture towards intelligence.

[0003] Moreover, with the increasing severity of water resource problems, the research on water-saving irrigation has attracted the attention of more and more countries and regions, especially the choice of irrigation methods. Among them, in drip irrigation technology, water is transported by pipes, and there will be no leakage and evaporation loss. Moreover, when irrigating, it generally only wets the soil near the roots of the crops. The irrigation flow is small, and surface runoff and deep leakage are not likely to occur. Water is supplied in a timely and appropriate amount according to the needs of crop growth. Or, for example, the irrigation method of using atomizing nozzles for sprinkler irrigation has a high water utilization rate and obvious water-saving effect, and has become a water-saving irrigation method currently recognized as having good development prospects.

[0004] However, on the one hand, the traditional technology integration and intelligence level of water conservancy irrigation with traditional pumping stations as the core is low, and it cannot effectively manage farmland irrigation and drainage. On the other hand, sprinkler irrigation and drip irrigation have high requirements for water quality. For example, in areas where the water source has a high sediment content, the pipeline is prone to blockage, and sprinkler irrigation and drip irrigation have different requirements for water supply pressure, which obviously can no longer meet the demand.

[0060] See also Figure 1 and Figure 2 In some embodiments, a pump station-based water irrigation system is provided, comprising:

[0061] A river channel 1 and a water diversion channel 2, one end of the water diversion channel 2 is connected to the river channel 1, and a trash rack 201 is arranged at the connection between the two;

[0062] A water diversion channel 5, the inlet end of which is in communication with the water diversion channel 2, and the elevation of the inlet end of the water diversion channel 5 is lower than the water level of the water diversion channel 2; an axial flow pump 7 is arranged in the water diversion channel 5, and a filter is arranged at the inlet end of the axial flow pump 7;

[0063] The outer wall 3 and the pump station, the outer wall 3 is cast and set under the ground surface, and the whole is in the shape of a cylindrical well. The pump station 4 is an integrated prefabricated pump station, and the pump station 4 is buried in the outer wall 3. The projection of the pump station 4 on the horizontal plane is arranged concentrically with the outer wall 2, and the water inlet end of the pump station 4 is not higher than the inlet end of the water diversion channel 5;

[0064] Sediment separator 6 and irrigation pipe system;

[0065] Among them, the water inlet end of the irrigation pipeline system is connected to the water outlet end of the pump station 4, the sediment separator 6 is buried on the side of the water inlet end near the pump station 4, the outlet end of the sediment separator 6 is connected to the side of the water inlet end of the pump station 4, the inlet end of the sediment separator 6 is connected to the water diversion channel 5, and the outlet end of the axial flow pump 7 is arranged opposite to the inlet end of the sediment separator 6.

[0066] In this example, the water diversion channel 2 is excavated according to the requirements of the actual irrigation area and is used to introduce river water into the irrigation area. The trash rack 201 at the inlet end of the water diversion channel 2 can intercept most large floating objects. The outer wall 3 cast underground and open at the top provides installation space and location for the pump station 4. The irrigation water can be introduced into the sediment separator 6 through the water diversion channel 5 for mud and water separation. The water inlet and outlet including the water diversion channel 5 and the sediment separator 6 are all set below the water level of the water diversion channel 2, and the pump station 4 is buried under the surface, which can also reduce the height difference between the water level of the water diversion channel 2 and the water inlet end of the pump station 4.

[0067] With this arrangement, under certain conditions, such as when the water level in the water diversion channel 2 is sufficiently higher than the inlet end of the water diversion channel 5, the gravity of the irrigation water is sufficient to overcome the resistance of the filtering part and enter the pump station 4, which not only ensures sufficient water pressure but also helps to reduce pumping energy consumption.

[0068] When the water pressure is low, the outlet end of the axial flow pump 7 is arranged directly opposite the inlet end of the silt separator 6, so that irrigation water can be pumped into the silt separator 6 at a relatively high flow rate, effectively increasing the water pressure at the water inlet end, ensuring that the water pressure at the water inlet end of the pump station 4 meets the requirements, or under the same water pressure requirement of the pump station 4, more filtering structures can be set in the silt separator 6 to obtain a better filtering effect, thereby improving the cleanliness of the water entering the pump station 4 and meeting the water-saving irrigation needs of subsequent irrigation systems such as sprinkler irrigation and drip irrigation, which is beneficial to ensuring the operating efficiency of the pump station 4.

[0069] At the same time, the pump station 4 can be customized and processed as an integrated pump station. When irrigating farmland, it can sort, analyze, quantify and collect the pump operation data, and then form various important indicators of farmland, so as to effectively manage farmland irrigation and drainage. And the staff can operate remotely through the computer. When problems occur, the fault problem can be analyzed through the network, which provides strong support for improving irrigation efficiency, quality and water saving.

[0070] See also Figure 1 and Figure 7 In some embodiments, the irrigation pipeline system includes a sprinkler irrigation pipeline and a drip irrigation pipeline. The pump station 4 is divided into a base 401 and an outer shell 402. The outer shell 402 includes a water storage tank 403 located below and an equipment cabin 404 located above. An inlet pipe 4022 is arranged on the side wall of the water storage tank 403. The inlet pipe 4022 is connected to the outlet end of the sediment separator 6. A first submersible pump 4031 and a second submersible pump 4032 are arranged in the water storage tank 403. An outlet pipe 4023 is arranged on the side wall of the equipment cabin 404. The water outlet end of the first submersible pump 4031 is connected to a first outlet pipe 4033, and the second submersible pump 4032 is connected to a second outlet pipe 4034. The first outlet pipe 4033 and the second outlet pipe 4034 are connected to the sprinkler irrigation pipeline and the drip irrigation pipeline after being led out of the pump station 4 and the outer wall 3 respectively.

[0071] The pump station 4 is a split structure consisting of a base 401 and a shell 402, which is convenient for separate hoisting and construction. The internal space is divided into a water storage tank 403 on the lower side and an equipment compartment 404 on the upper side. The first submersible pump 4031 and the second submersible pump 4032 in the water storage tank 403 are connected to the sprinkler irrigation pipeline and the drip irrigation pipeline of the irrigation system through independent pipes, namely the first outlet pipe 4033 and the second outlet pipe 4034. In this way, the first submersible pump 4031 and the second submersible pump 4032 share the water storage tank 403 but operate relatively independently, which is conducive to the independent control, monitoring and adjustment of the water supply of the sprinkler irrigation pipeline and the drip irrigation pipe, and does not hinder the working process due to failures.

[0072] See also Figure 1 and Figure 3 In some embodiments, the sediment separator 6 includes a primary separation chamber 601 and a secondary separation chamber 602 which are arranged closely to each other; the water inlet of the sediment separator 6 is opened on the primary separation chamber 601, and the primary separation chamber 601 and the secondary separation chamber 602 are connected by setting a first water inlet 6021, and the first water inlet 6021 is arranged directly opposite to the water inlet of the sediment separator 6, and two guide plates 6011 arranged in an eight-shaped shape are arranged in the primary separation chamber 601, and a cavity is formed between the two guide plates 6011, and the cavity is smaller on one side adjacent to the first water inlet 6021, and larger on the other side and is arranged directly opposite to the water inlet of the sediment separator 6, and a primary filter 6012 is arranged between the two guide plates.

[0073] Among them, a first water outlet 6023 is set on the side of the secondary separation chamber 602 relative to 6021. The setting height of the first water outlet 6023 is lower than the first water inlet 6021. A second filter 6022 is set inside the first water outlet 6023. The first water outlet 6023 is connected to the inlet pipe 4022.

[0074] In this example, a primary separation chamber 601 and a secondary separation chamber 602 are provided to filter the irrigation water. When working, the axial flow pump 7 pumps the irrigation water into the water inlet of the silt separator 6, and the first water inlet 6021 is arranged opposite to the water inlet of the silt separator 6. The inner cavity enclosed by the two guide plates 6011 and the primary filter screen 6012 arranged thereon are also arranged opposite to the first water inlet 6021. In this way, the irrigation water entering the silt separator 6 shrinks at the two guide plates 6011 to increase the flow rate, and after most of the silt is filtered out by the primary filter screen 6012, it enters the secondary separation chamber 602 from the first water inlet 6021. The axial flow pump 7 pumps the irrigation water into the silt separator 6 at a higher flow rate. The axial flow pump 7 pumps the irrigation water in at a higher flow rate, which is conducive to removing the silt adhered to the primary filter screen 6012, thereby reducing blockage.

[0075] See also Figure 3In some embodiments, a first sedimentation trough 6013 roughly in the shape of an inverted cone is provided at the bottom of the first separation chamber 601, and a first drain valve 6014 is provided at the bottom outlet of the first sedimentation trough 6013; a second sedimentation trough 6024 roughly in the shape of an inverted cone is provided at the bottom of the secondary separation chamber 602, and a second drain valve 6025 is provided at the bottom outlet of the second sedimentation trough 6024.

[0076] In this example, the first sedimentation tank 6013 is arranged at the bottom of the first separation chamber 601 to collect the sediment, wherein the projection of the guide plate 6011 located at the lower side in the vertical direction roughly overlaps with the bottom outlet of the first sedimentation tank 6013, so that part of the sediment that sinks in the first filter screen 6012 can slide down through the gap on the left side of the guide plate 6011 and settle in the first sedimentation tank 6013, and on the other hand, the first sedimentation tank 6013 can be covered by the guide plate 6011, so that the irrigation water pumped in by the axial flow pump 7 at a higher flow rate will not directly impact the second sedimentation tank 6024, thereby avoiding the sediment from surging. The second filter screen 6022 is arranged near the extension of the second sedimentation tank 6024, leaving no dead corner for sediment accumulation, and ensuring that it settles in the second sedimentation tank 6024 as much as possible.

[0077] In addition, the first sewage valve 6014 and the second sewage valve 6025 are respectively provided at the bottom of the first sedimentation tank 6013 and the second sedimentation tank 6024. It is preferred to provide an automatically controllable valve to facilitate sewage control. During construction, drainage channels, ditches, etc. can be preset below the sediment separator 6 to remove the precipitated sediment. To reduce blockage, when cleaning, the outlet of the sediment separator 6 can be closed first. For example, closing the water inlet valve when entering the pump station 4 is a relatively simple method. Then open the first sewage valve 6014 and the second sewage valve 6025, and start the axial flow pump 7 to provide positive pressure water flow to flush the sediment separator 6, which is conducive to the smooth discharge of internal sediments.

[0078] See also Figure 4 In some embodiments, the exterior wall 3 includes a hollow cylindrical body 301 cast on the outside, a reinforcement layer 302 on the inside, and a base plate 303 at the bottom, and a blade foot 3011 is arranged at the bottom of the body 301; wherein the body 301 and the reinforcement layer 302 are connected by a plurality of pre-embedded anchor rods 305, the base plate 303 is arranged at the bottom of the body 301 to form a closure for the body 301, and the base plate 303 and the top surface of the blade foot 3011 are abutted against the bottom of the reinforcement layer 302 and the extension of the base plate 303.

[0079] The cooperation between the cylinder 301 and the blade foot 3011 can ensure the stability of the overall foundation structure. At the same time, the setting of the reinforcement layer 302 ensures the stability of the entire outer wall 3 structure, and the reinforcement layer 302 forms a vertical positioning for the bottom plate 303 to prevent the floating of groundwater from affecting its stability. The buoyancy of the bottom plate 303 is borne by the reinforcement layer 302 and then dispersed to the cylinder 301, ensuring the stability of the structure and protecting the safety of the pump station 4 and each connecting pipeline.

[0080] See also Figure 4 In some embodiments, the base 401 is fixed on the bottom plate 303, the bottom of the shell 402 is fixedly connected to the top of the base 401, a sealing layer 308 is laid under the cylinder 301, the sealing layer 308 is at the same height as the blade foot 3011, a backfill layer 309 is arranged between the reinforcement layer 302 and the outer wall of the pump station 4, an annular positioning seal 304 is arranged on the bottom plate 303, the outer peripheral surface of the positioning seal 304 is fixed to the reinforcement layer 302, and the inner wall of the positioning seal 304 is against the base 401.

[0081] In this example, a positioning seal 304 is provided to seal the gap between the bottom plate 303 and the reinforcement layer 302 on the one hand, and to position the base 401 of the pump station 4 on the other hand, which helps to align during installation and ensure a stable and firm installation structure.

[0082] See also Figure 6 An inlet sleeve 306 and an outlet sleeve 307 are pre-buried on the outer wall 3 corresponding to the inlet pipe 4022 and the outlet pipe 4023 respectively. The inlet sleeve 306 and the inlet pipe 4022 are connected as well as the outlet sleeve 307 and the outlet pipe 4023 are connected via a hose. The first outlet pipe 4033 and the second outlet pipe 4034 extend out of the pump station 4 through the outlet pipe 4023, the hose and the outlet sleeve 307 in sequence.

[0083] Among them, the use of a hose to connect the pump station 4 and the water inlet and outlet on the outer wall 3 can compensate for the errors generated during the installation of the two, making the connection operation between the two easier to carry out and maintaining effective penetration, ensuring the sealing of the pipeline structure at the water inlet end. And on the outlet side, the outlet sleeve 307, the outlet pipe 4023 and the hose protect the first outlet pipe 4033 and the second outlet pipe 4034 arranged side by side, especially the pipeline part from the pump station 4 to the outer wall 3, to avoid damage to the first outlet pipe 4033 and the second outlet pipe 4034 due to later ground driving, floating of the pump station structure, etc.

[0084] See also Figure 6 and Figure 7In some embodiments, the water conservancy irrigation system further includes: an observation well 8, which is arranged on a side adjacent to the outlet casing 307. The first water outlet pipe 4033 and the second water outlet pipe 4034 extend from the outlet casing 307 and enter the observation well 8. A flow meter 801 and a pressure gauge 802 are respectively arranged in the observation well 8 corresponding to the first water outlet pipe 4033 and the second water outlet pipe 4034. In addition to referring to the operating data uploaded by the pump station 4, the staff can be assisted to intuitively observe the water flow and water pressure of the first water outlet pipe 4033 and the second water outlet pipe 4034, thereby facilitating the judgment of the irrigation conditions in the area or the operating conditions of the pump station 4.

[0085] See also Figure 6 In some embodiments, the water conservancy irrigation system further includes: a three-way reversing valve 4041 and a booster pump 4042, both of which are disposed in the equipment cabin 404;

[0086] Among them, the inner end of the inlet pipe 4022 is connected to the inlet end of the three-way reversing valve 4041, one outlet of the three-way reversing valve 4041 is connected to the water storage tank 403, and the other outlet is connected to the water inlet of the boosting pump 4042, and the water outlet of the boosting pump 4042 is connected to the water storage tank 403.

[0087] During operation, the water outlet of the sediment separator 6 is sent to the pump station 4 through the inlet pipe 4022, and enters the water storage tank 403 through an outlet of the three-way reversing valve 4041, and is pumped for irrigation by the first submersible pump 4031 and the second submersible pump 4032. This is the flow mode under normal water quality and water pressure conditions. When the water pressure detection set up finds an abnormality, such as a large difference in water pressure at the inlet and outlet ends of the sediment separator 6, or there is a shortage of water supply in the pump station 4, it can be determined that the sediment separator 6 is blocked by siltation or pipeline blockage, resulting in the water storage tank 403 being unable to obtain sufficient water replenishment. At this time, the booster pump 4042 can be operated to assist in increasing the water pressure at the outlet end of the sediment separator 6 to ensure that the water storage tank 403 is sufficiently replenished with water to ensure that the irrigation plan is completed on schedule.
