Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and irrigation, in particular to a water conservancy and irrigation channel with a water level regulating function. Background Art

[0002] Irrigation canals are hydraulic ditch structures used to irrigate farmland, forests, and other areas. Water from a source is distributed through an impermeable main canal to the areas requiring irrigation. The water in the main canal then flows into branch canals for irrigation. However, during flood seasons with heavy rainfall or high water levels at the source, water flows from the main canal into the branch canals at high volumes, which can easily lead to overirrigation and affect plant growth. To prevent overirrigation and plant drowning, flow control in the branch canals is necessary.

[0003] For example, the patent with announcement number CN220685986U discloses a water conservancy irrigation channel, comprising a main channel and a branch channel that are interconnected. The branch channel is fixedly connected to a water reservoir below, and chutes are provided on both side walls of the branch channel. A floating plate is slidably connected in the chutes. The floating plate is slidably connected to the branch channel. An inlet pipe is provided on the inner bottom surface of the branch channel. The top of the inlet pipe is higher than the inner bottom surface of the branch channel. The inner cavity of the branch channel is connected to the inner cavity of the water reservoir through the inlet pipe. The rising floating plate reduces the flow cross-sectional area of the branch channel, that is, reduces the water flow into the branch channel to avoid over-irrigation. The chute guides the floating plate, ensuring that the floating plate can move in the vertical direction. At the same time, when the floating plate floats, the chute also supports the floating plate, helping the floating plate to offset the impact force of the water flow. The height of the inlet pipe determines the water level in the branch channel when the floating plate begins to float. The water level can be adjusted later by installing an external pipe on the inlet pipe.

[0004] Although the amount of water flowing into the branch canal can be controlled by setting up a reservoir and a float at the bottom of the branch canal, the water flowing in the irrigation canal may contain a large amount of impurities such as silt, aquatic plants, etc. These impurities may enter the reservoir with the water flow and settle in the reservoir, thereby causing the reservoir to be unable to be used normally. At the same time, a large amount of silt settles in the reservoir, which may cause the float to be unable to sink smoothly. When the water volume in the main canal is small, the float that cannot sink will block the water flow, resulting in the water flow being unable to enter the branch canal, hindering normal irrigation, and having a great adverse impact on water conservancy irrigation.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1 - Figure 7 A water conservancy irrigation channel with a water level regulation function includes a main channel 1, and a plurality of diversion ports 101 are opened on both sides of the main channel 1. A plurality of branch channels 2 are fixedly connected to both sides of the main channel 1, and the plurality of branch channels 2 are respectively connected to the plurality of diversion ports 101. Baffles 3 are fixedly connected to the plurality of diversion ports 101, and water inlets 301 are opened on the side walls of the plurality of baffles 3 near one end of the bottom of the main channel 1. A scraping assembly is connected to one side of the plurality of baffles 3 located on the main channel 1, and a flow limiting assembly is connected to one side of the plurality of baffles 3 near the adjacent branch channels 2.

[0025] like Figure 1 - Figure 7As shown, the structure of a water conservancy irrigation channel with a water level regulating function in the present invention is similar to that of an existing water conservancy irrigation channel with a water level regulating function, such as a water conservancy irrigation channel disclosed in patent publication number CN220685986U. The main improvement of the present invention is to avoid blockage between the main channel 1 and the branch channel 2, thereby improving the smoothness of the water flow in the irrigation channel. Figures 1 to 7 As shown, when the water conservancy irrigation channel with water level regulation function in the present invention is in use, the water in the main channel 1 flows into the multiple branch channels 2 respectively through the water inlets 301 of the multiple baffles 3. In this process, the water flow drives the scraping component to scrape on the water inlet side of the baffle 3, thereby scraping impurities that move to the outside of the water inlet 301 with the flow of water, such as aquatic plants, dead leaves, etc., from the water inlet 301, thereby avoiding the impurities from clogging the water inlet 301. At the same time, the water inlet 301 is adjusted by the flow limiting component, thereby controlling the amount of water flowing into the branch channel 2 through the water inlet 301, thereby avoiding the problem of excessive irrigation caused by excessive water flowing into the branch channel 2.

[0026] like Figure 1 - Figure 7 As shown, a filter screen 4 is fixedly connected to the inner wall of the water inlet 301 near one end of the main channel 1. By installing the filter screen 4 on the inner side of the water inlet 301, the water flowing into the branch channel 2 can be filtered, thereby preventing impurities and aquatic organisms from entering the branch channel 2 and then entering the farmland, causing damage to the crop seedlings in the farmland.

[0027] like Figure 1 - Figure 7 As shown, the scraping assembly includes a rotating block 5 and a plurality of scraping bars 6. One end of the rotating block 5 is connected to the baffle 3 on one side of the main channel 1. The plurality of scraping bars 6 are fixedly connected to the outer wall of the rotating block 5, and the plurality of scraping bars 6 are slidably connected to the baffle 3. When water flows from the main channel 1 through the water inlet 301 to the branch channel 2, it will have a certain impact effect on the plurality of scraping bars 6, thereby driving the rotating block 5 to rotate on the side of the baffle 3, so that the scraping bars 6 can swing outside the water inlet 301, thereby scraping off impurities near the water inlet 301. The scraped impurities can then flow away from the main channel 1 downstream with the water flow, which can prevent aquatic organisms such as snails from attaching to the vicinity of the water inlet 301, causing blockage of the water inlet 301 and affecting the flow of water at the water inlet 301.

[0028] like Figure 6 As shown, a T-shaped rotation groove 501 is formed on the side of the rotating block 5 near the baffle 3. A T-shaped fixed block 7 is rotatably connected to the T-shaped rotation groove 501. The thinner end of the T-shaped fixed block 7 passes through the T-shaped rotation groove 501 and is fixedly connected to the baffle 3. When the rotating block 5 is impacted by water flow, the T-shaped rotation groove 501 is inserted into the T-shaped fixed block 7, and the rotating block 5 can rotate on the side of the baffle 3.

[0029] like Figure 1 - Figure 7 As shown, the end of the scraper bar 6 away from the rotating block 5 is designed as a knife edge. The end of the scraper bar 6 is designed to be knife-edge-shaped. When water plants approach the scraper bar 6 with the water flow, they will be cut by the knife edge at the end of the scraper bar 6, thereby reducing the possibility of water plants being entangled in the scraper bar 6 and improving the scraper bar 6's scraping effect on impurities at the water inlet 301.

[0030] like Figure 1 - Figure 7 As shown, the flow limiting assembly includes a flow limiting plate 8 and two T-shaped slides 9. A connecting port 801 matching the water inlet 301 is provided through the middle position of the flow limiting plate 8. T-shaped slides 802 are provided on both ends of the flow limiting plate 8 close to the side of the baffle 3. The two T-shaped slides 9 are fixedly connected to the side of the baffle 3 close to the adjacent branch channel 2. The flow limiting plate 8 is slidably connected to the two T-shaped slides 9 through the two T-shaped slides 802. The top of the flow limiting plate 8 is connected to an adjustment assembly. The regulating assembly can drive the flow limiting plate 8 to slide up and down on the two T-shaped slides 9 along the side of the baffle 3. When the connecting port 801 coincides with or is partially connected to the water inlet 301, the water in the main channel 1 can enter the branch channel 2 through the water inlet 301 and the connecting port 801. When the flow limiting plate 8 moves upward and the connecting port 801 is misaligned with the water inlet 301, the bottom of the flow limiting plate 8 can block the water inlet 301, thereby blocking the flow of water from the main channel 1 to the branch channel 2, avoiding excessive water in the branch channel 2, causing excessive irrigation, and affecting plant growth.

[0031] like Figure 1 - Figure 7As shown, the adjustment assembly includes a floating block 10 and a threaded rod 11. The floating block 10 is located above the flow limiting plate 8. A T-shaped adjustment hole 803 is opened in the middle position of the top of the flow limiting plate 8. A T-shaped adjustment block 12 is rotatably connected in the T-shaped adjustment hole 803. The thinner end of the T-shaped adjustment block 12 passes through the T-shaped adjustment hole 803 and is fixedly connected to the threaded rod 11. The other end of the threaded rod 11 passes through the floating block 10 and is fixedly connected to a hand-tightened cap 13. The threaded rod 11 is threadedly connected to the floating block 10. By setting the floating block 10, when the water volume in the branch channel 2 does not reach the bottom of the floating block 10, the communication port 801 of the flow-limiting plate 8 is connected with the water inlet 301, and the water in the main channel 1 can enter the branch channel 2. As the water volume in the branch channel 2 gradually increases and the water level continues to rise, when the water level contacts the floating block 10, the floating block 10 is gradually lifted upward. At this time, the floating block 10 lifts the flow-limiting plate 8 upward through the threaded rod 11, gradually reducing the water volume of the branch channel 2, and after the water level rises to a certain level, the communication port 80 1 is completely misaligned with the water inlet 301, and the flow between the main channel 1 and the branch channel 2 is completely cut off. As the water in the branch channel 2 flows into the farmland and downstream, the water level gradually drops, and the connecting port 801 is connected with the water inlet 301 again, and the water in the main channel 1 can continue to flow into the branch channel 2, thereby always maintaining the water volume in the branch channel 2 and improving the irrigation effect of the branch channel 2. At the same time, by rotating the threaded rod 11, the distance between the floating block 10 and the flow limiting plate 8 can be adjusted, thereby adjusting the water level height of the branch channel 2, which is convenient for the irrigation effect of the branch channel 2 on the farmland.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
