[0002] It is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production. In order to make more rational use of water resources during rural construction, people generally irrigate crops through specific water conservancy irrigation systems. Water pumps are an important part of water conservancy irrigation systems.

[0003] However, when people use water pumps to irrigate crops with water from the reservoir, they often encounter the problem that large debris such as leaves, water plants and other fibers floating in the reservoir cannot be adsorbed into the water pump, causing such debris to block the water inlet of the water pump, resulting in insufficient water pressure sucked by the water pump, greatly reducing the water pushing ability of the water pump, resulting in a decrease in head, and making it impossible to transport the water in the reservoir to a distant place, and thus unable to irrigate distant crops. There are certain limitations.

A cutting knife 14 is fixedly installed on the third rotating rod 13. Due to the size difference between the first large gear 27, the first small gear 11, the second large gear 8 and the second small gear 15, the cutting knife 14 will rotate faster than the propeller 4, so that the cutting knife 14 can rotate quickly to cut the water plants, leaves and other fiber debris entering the fixed pipe 2, so that the debris becomes small pieces, which can be adsorbed into the water pump body 1 and then transported to the external water pipe through the water outlet together with the water, so as to prevent such impurities from blocking the water inlet of the water pump body 1, making the water pressure of the water pump insufficient, resulting in a significant reduction in the water pump's ability to push water, resulting in a reduction in lift.

[0028] In order to protect the first large gear 27, the second large gear 8, the first small gear 11 and the second small gear 15, and prevent the chopped water grass, leaves and other fibers and other debris from adhering to the slots of the first large gear 27, the second large gear 8, the first small gear 11 and the second small gear 15, and affecting the meshing degree between the first large gear 27, the second large gear 8, the first small gear 11 and the second small gear 15, a protective cover 7 is provided in the fixed tube 2, and the first large gear 27, the second large gear 8, the first small gear 11 and the second small gear 15 are prevented from being attached to the slots of the first large gear 27, the second large gear 8, the first small gear 11 and the second small gear 15. The first rotating rod 3 and the second pinion 15 are both located in the protective cover 7, the first rotating rod 3 and the third rotating rod 13 are both rotatably connected to the protective cover 7, the second fixed plate 6 is fixedly connected to the protective cover 7, and a plurality of through holes are respectively opened on the outer walls on both sides of the protective cover 7, and isolation nets 10 are respectively fixedly installed in the plurality of through holes. In order to remove impurities adhering to the isolation net 10 and keep the isolation net 10 in a cleared state at all times, a cleaning brush 28 is fixedly installed on the third rotating rod 13, and the bristles on the cleaning brush 28 are in contact with the isolation net 10.

[0029] In order to grind the cutting blade 14 so that the cutting blade 14 always keeps a sharp state to crush impurities, a bidirectional screw 17 is rotatably installed on the third fixed plate 9, and two movable plates 16 are threadedly installed on the bidirectional screw 17, and the two movable plates 16 are slidably connected with the fixed tube 2. In order to limit the movable plate 16, and then the bidirectional screw 17 rotates to drive the movable plate 16 to move, a limiting groove is provided on the fixed tube 2, and the tops of the two movable plates 16 extend into the limiting groove and are slidably connected with the inner wall of the limiting groove. The two movable plates 16 slide respectively. Two sliding rods 23 are installed, and one end of the four sliding rods 23 is fixedly installed with a mounting plate 26. Grinding rollers 25 are respectively provided on both sides of the cutting knife 14, and the two grinding rollers 25 are rotatably connected to the four mounting plates 26. Since the grinding rollers 25 and the mounting plates 26 are rotatably installed, when the grinding rollers 25 grind the cutting knife 14, the grinding rollers 25 will also rotate under the action of the cutting knife 14, so that the circumferential surface of the grinding rollers 25 can grind the cutting knife 14, so that the utilization rate of the grinding rollers 25 is maximized.

[0030] In order to make the grinding roller 25 elastically contact with the cutting knife 14 and prevent the cutting knife 14 from directly contacting the grinding roller 25 hard, causing damage to the blade and affecting the service life of the cutting knife 14, compression springs 24 are movably sleeved on the four sliding rods 23. In order to increase the service life of the compression springs 24, the four compression springs 24 are tin-plated springs, and one end of the four compression springs 24 is fixedly connected to the corresponding mounting plates 26, and the other ends of the four compression springs 24 are fixedly connected to the corresponding moving plates 16, and the other ends of the four sliding rods 23 are fixedly installed with limit plates 20.

[0031] In order to protect the bidirectional screw 17 and prevent water from directly contacting the bidirectional screw 17, which would cause the surface of the bidirectional screw 17 to oxidize and rust, thus affecting its service life, a movable sleeve on the bidirectional screw 17 is provided with a left protective telescopic tube 18, a middle protective telescopic tube 19 and a right protective telescopic tube, and one end of the left protective telescopic tube 18 is fixedly connected to the movable plate 16, and the other end of the left protective telescopic tube 18 is fixedly installed with an annular plate 22, and a rotating sealing sleeve of the annular plate 22 is provided on the bidirectional screw 17. In order to make it more convenient for people to rotate the bidirectional screw 17, a rotating handle 21 is fixedly installed at one end of the bidirectional screw 17, and a friction sleeve is provided on the rotating handle 21. The friction sleeve prevents people from slipping when rotating the rotating handle 21, thus affecting work efficiency. The two ends of the middle protective telescopic tube 19 are respectively fixedly connected to the two movable plates 16, and the two ends of the two right protective telescopic tubes are respectively fixedly connected to the movable plate 16 and the third fixed plate 9.

[0032] In order to remove impurities adhering to the isolation net 10 and keep the isolation net 10 in a cleared state at all times, a cleaning brush 28 is fixedly mounted on the third rotating rod 13 , and the bristles on the cleaning brush 28 are in contact with the isolation net 10 .

[0033] The working principle of the water conservancy irrigation system for rural construction provided by the present invention is as follows; in the initial state, the external water pipe is connected to the water outlet of the water pump body 1, and then the device is placed in the reservoir, the water pump body 1 is started, and the water in the reservoir is transported to the crops to complete the irrigation of the crops. When the aquatic plants, leaves and other fiber-like debris in the reservoir are adsorbed into the fixed pipe 2, the water flows rapidly in the fixed pipe 2 to drive the propeller 4 to rotate, and the rotation of the propeller 4 drives the first rotating rod 3 to rotate, and the rotation of the first rotating rod 3 drives the first large gear 27 to rotate, so that the first small gear 11 rotates, and the second small gear 15 is driven to rotate through the second rotating rod 12 and the second large gear 8, and then the third rotating rod 13 is driven to rotate to rotate the cutting knife 14. Due to the size difference between the first large gear 27, the first small gear 11, the second large gear 8 and the second small gear 15, the cutting knife 14 will be faster than the rotation speed of the propeller 4, so that the cutting knife 14 can be quickly rotated to enter the fixed The fibers such as water plants and leaves in the pipe 2 are cut into small pieces, which can then be adsorbed into the water pump body 1 and transported to the external water pipe through the water outlet to prevent such impurities from blocking the water inlet of the water pump body 1, making the water pressure sucked by the water pump insufficient, resulting in a greatly reduced ability of the water pump to push water, resulting in a reduced lift. The handle 21 is rotated to drive the bidirectional screw 17 to rotate and drive the two moving plates 16 to approach each other, thereby making the grinding rollers 25 approach each other and contact with the cutting knife 14. The cutting knife 14 is polished by the grinding roller 25, so that the cutting knife 14 always remains sharp to crush the impurities. Since the grinding roller 25 and the mounting plate 26 are rotatably mounted, when the grinding roller 25 polishes the cutting knife 14, the grinding roller 25 will also rotate under the action of the cutting knife 14, so that the circumferential surface of the grinding roller 25 can polish the cutting knife 14, so that the utilization rate of the grinding roller 25 is maximized.

[0034] Compared with the related art, the water conservancy irrigation system for rural construction provided by the present invention has the following beneficial effects:

[0035] The present invention provides a water conservancy irrigation system for rural construction. First, an external water pipe is connected to the water outlet of a water pump body 1, and then the device is placed in a reservoir. The water pump body 1 is started to transport water in the reservoir to crops to complete the irrigation of crops. When aquatic plants, leaves and other fiber-like debris in the reservoir are adsorbed into a fixed pipe 2, water flows rapidly in the fixed pipe 2 to drive a propeller 4 to rotate. The rotation of the propeller 4 enables a cutting knife 14 to rotate rapidly to cut the aquatic plants, leaves and other fiber-like debris entering the fixed pipe 2, so that the debris is turned into small pieces, adsorbed into the water pump body 1 and then transported to the external water pipe through the water outlet, so as to prevent such impurities from blocking the water inlet of the water pump body 1, so that the water pressure sucked by the water pump is insufficient, resulting in a greatly reduced water pushing ability of the water pump and a reduced lift. The handle 21 is rotated to drive the grinding rollers 25 to approach each other to grind the cutting knife 14, so that the cutting knife 14 always keeps a sharp state to crush the impurities.
