[0052] As a further embodiment of the present invention, a method for using an irrigation device for a water conservancy project comprises the following steps:

[0053] Step 1: Install the canal body 1 in the direction of water flow through the longitudinal groove 24. When water flows into the canal body 1, insert the two baffles 16 into the two second slots 32 respectively so that the baffles 16 abut against the third filter screen 23, filter the impurities in the canal body 1 through the first filter screen 4, and deliver water to the farmland through the transverse groove 20;

[0054] Step 2: After the water supply to the farmland is completed, the impurities on the first filter screen 4 are cleaned, and then the two baffles 16 are pulled out from the two second slots 32, and then inserted into the first slots 21 to block the transverse slots 20 and separate the farmland from the transverse slots 20;

[0055] Step 3: When there is too much water in the farmland, pull out the two baffles 16 from the two first slots 21, and then insert them into the two third slots 33 respectively, so that the water in the farmland is discharged into the canal body 1. In this process, the first filter screen 4 is used to filter the impurities flowing with the water in the farmland.

[0056] Working principle of the present invention:

[0057] When the present invention is in use, first, when the canal body 1 is supplied with water, the water flows from the diverter plate 18 to the mounting frame 30, and is installed in the direction of the water coming from the longitudinal groove 24 toward the canal body 1. When water comes into the canal body 1, the water can enter the longitudinal groove 24, and then enter the through groove 29. After being transported by the through groove 29, the water is transported to the farmland. It should be noted that the farmland is usually located on both sides of the canal.

[0058] When the canal is supplying water, first, the slider 31 slides upward on the slide rail 10 so that the photovoltaic panel 5 is suspended above the two through grooves 29, and then the baffle 16 inserted in the first slot 21 is inserted into the second slot 32. The water flow in the canal body 1 will enter the through groove 29 through the longitudinal groove 24. In this process, the water flow will be filtered by the second filter screen 22. Under the action of the inclined surface of the second filter screen 22, impurities such as pesticide packaging bags and plastic garbage floating on the water surface will be filtered to the top of the first filter screen 4, and the water will pass through the filtration of the second filter screen 22 into the space below the first filter screen 4 in the through groove 29, and then pass through the third filter screen 23 into the farmland. The flow of water can also realize the back flushing of the third filter screen 23.

[0059] After the baffle 16 is inserted into the second slot 32, the bottom wall of the baffle 16 will abut against the top wall of the third filter 23. The abutment between the baffle 16 and the third filter 23 can effectively prevent impurities such as pesticide packaging bags and plastic garbage collected on the first filter 4 from entering the farmland through the space between the third filter 23 and the top wall of the transverse groove 20, which is beneficial to protect the farmland. After the water supply to the farmland is completed, the impurities on the first filter 4 can be cleaned.

[0060] After water is delivered to the farmland, in order to retain the water in the farmland, the two baffles 16 are pulled out from the two second slots 32 and then inserted into the first slot 21 to seal the transverse groove 20 and separate the farmland from the transverse groove 20, which is beneficial to block the water in the farmland and prevent the water entering the farmland from flowing back into the canal body 1.

[0061] It should be noted that in the prior art, the two ends of the canal body 1 are respectively connected to a water supply end and a drainage end. The water supply end is connected to the river channel. During irrigation, water is supplied to the canal body 1 by a water pump. The drainage end is connected to a reservoir to discharge excess water in the farmland. After the water pump stops supplying water, the amount of residual water in the canal body 1 is usually small. This is common knowledge in the field and will not be disclosed in detail here.

[0062] When there is too much water in the farmland due to heavy rain or other reasons, it is necessary to drain the farmland in time. The two baffles 16 are pulled out from the two first slots 21 and then plugged into the two third slots 33 respectively. At this time, since there is no water supply in the canal body 1, the water level of the farmland is higher than the water level in the canal body 1. After the baffle 16 is taken out of the first slot 21 and inserted into the third slot 33, the water in the farmland will enter the through slot 29 through the transverse slot 20, and then enter the longitudinal slot 24 through the through slot 29, and finally flow into the canal body 1. The water in the farmland is drained into the canal body 1 by utilizing the height difference of the water. In the process of entering the water channel body 1, the third filter screen 23 will filter out impurities such as pesticide packaging bags, plastic garbage and the like in the farmland. The inclined design of the third filter screen 23 and the impact of the water flow will allow the impurities to enter the top of the first filter screen 4, and the first filter screen 4 will be used to filter the impurities flowing with the water flow in the farmland. At this time, the baffle 16 is inserted into the third slot 33, and the bottom wall plate of the baffle 16 will abut against the second filter screen 22, so that the impurities can be retained above the first filter screen 4 to prevent the impurities from flowing back into the water channel body 1. After the water in the farmland is filtered, the second filter screen 22 will be backwashed to prevent the second filter screen 22 from being blocked.

[0063] By setting the first filter screen 4, the second filter screen 22 and the third filter screen 23, it is possible to effectively filter out impurities in the farmland, and also to filter out impurities in the water channel body 1. In the process of supplying water to the farmland and draining excess water from the farmland, the second filter screen 22 and the third filter screen 23 can be effectively backwashed, and the second filter screen 22 and the third filter screen 23 can be self-cleaned to a certain extent without the need for technical personnel to perform special dredging work.

[0064] By setting the mud storage tank 12, when water flows in the water channel body 1, the mud at the bottom of the water channel body 1 will flow to the mud storage tank 12 for temporary storage, which is beneficial to reduce the mud content in the water channel body 1. In the process of water supply to the water channel body 1, the mud will become silt after being moistened by water and has a certain fluidity. At this time, by turning the handle 27, the handle 27 drives the column 11 to rotate, and then the column 11 drives the spiral plate 15 and the arc plate 13 to rotate. In the process of rotation, the arc plate 13 will push the silt in the mud storage tank 12 toward the rotation of the column 11. The spiral plate 15 is pushed by the center of motion, and the silt is transported upward so that the silt can be effectively discharged from the sludge storage tank 12 to achieve the cleaning of the canal body 1. In the process of the silt flowing upward, the silt will enter the collecting tank 19 through the cylinder 14, and then spread to the extension tank 3 through the collecting tank 19. The silt in the sludge storage tank 12 usually contains rich organic matter. The silt in the extension tank 3 and the collecting tank 19 can be shoveled into the farmland to increase the fertility of the farmland. The silt in the collecting tank 19 and the extension tank 3 can also be shoveled onto the ridge to achieve the purpose of reinforcing the ridge.

[0065] During the normal growth of crops, the baffle 16 is inserted into the first slot 21, and the slider 31 is moved from the top of the slide rail 10 to the bottom of the slide rail 10, so that the slider 31 drives the photovoltaic panel 5 to descend. After descending, the photovoltaic panel 5 will be blocked at the top of the through groove 29, thereby shielding the through groove 29 and preventing impurities in the air from blocking the first filter 4. At the same time, the photovoltaic panel 5 will generate electricity when exposed to sunlight, and the second wire will be used to transmit the electrical energy to the battery 9 for storage. When working at night, the battery 9 can be used to power the lighting lamp 8, so that the lighting lamp 8 can illuminate the water channel body 1 and the farmland on both sides thereof, which is convenient for farmers to irrigate the farmland. At the same time, through the setting of the universal hose 7, the lighting position of the lighting lamp 8 can be effectively adjusted.

[0066] By setting the connecting spring 26, the movable column 17 can be elastically shaken, and a plastic bag is tied to the outer side of the annular groove 25. When the plastic bag swings with the wind, the connecting spring 26 will also shake, thereby increasing the swing amplitude of the plastic bag, thereby playing a role similar to a scarecrow, driving away birds in the farmland and preventing them from eating crops in the farmland. When working at night, the lighting lamp 8 can also be used to illuminate the plastic bag to play a role similar to a colored lantern.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
