Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and irrigation, in particular to a farmland water conservancy and irrigation device. Background Art

[0002] Farmland irrigation equipment is a device or system used to transport and distribute irrigation water to farmland. It uses pipes, channels, sprinklers and other components to divert water from water sources (such as rivers, reservoirs, groundwater, etc.) to farmland to meet the moisture requirements of crop growth.

[0003] Common irrigation methods include drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and traditional flood irrigation. Drip irrigation delivers water drop by drop directly to the roots of crops through drippers, saving water and being highly efficient. Sprinkler irrigation uses sprinkler nozzles to spray water into tiny droplets, evenly covering the fields. These devices not only improve irrigation efficiency but also reduce water waste, playing a significant role in ensuring food security and sustainable agricultural development.

[0004] In the process of irrigating a small area of ​​farmland, irrigation is generally carried out through a DC water pump. When the DC water pump is placed into a well through a pull rope, if the placement depth is too large, it will cause the DC water pump to collide with the well wall. In addition, the distance between the fixed end of the pull rope and the DC water pump is too large, and the swing amplitude of the DC water pump is large, which affects the stability of the DC water pump operation. Therefore, a farmland water conservancy irrigation device is proposed to address the above problems. Summary of the Invention

A circular hole 54 is opened in the middle of the central column 52, and a straight tube 57 is fixedly connected to the inside of the air hole 56; the positioning unit 6 includes a first rotating rod 61, one end of the first rotating rod 61 is fixedly connected to the first rotating shaft 62, the other end of the first rotating rod 61 is connected to the second rotating rod 63 through a damping member 65, and the other end of the second rotating rod 63 is fixedly connected to the second rotating shaft 64.

[0038] As a further technical solution of this solution, the damping member 65 includes a damping block 651, one side of which is provided with a damping groove 652, and the other side of which is fixedly connected to a protruding block 653, and the upper and lower ends of the protruding block 653 are fixedly connected to a third rotating shaft 654. Through this arrangement, the stability of the contact between the damping member 65 and the inner wall of the water well can be increased;

[0039] As a further technical solution of this solution, the first rotating rod 61 and the second rotating rod 63 are both rotatably connected to the third rotating shaft 654. There are multiple first rotating rods 61, second rotating rods 63 and damping members 65, and there is a one-to-one correspondence between the first rotating rod 61, the second rotating rod 63 and the damping member 65. Through the above arrangement, the stability of the damping member 65 driven by the first rotating rod 61 and the second rotating rod 63 can be ensured during the movement.

[0040] As a further technical solution for implementing this scheme, a DC water pump 1 includes a pump body 11, a water inlet network 12 is installed at the bottom end of the pump body 11, and a drain outlet 13 is installed on one side of the lower end of the pump body 11.

[0041] As a further technical solution of this solution, the center column 52 passes through the fixed circular plate 51, and the bottom end of the pull rope 3 is set in the circular hole 54 opened on the inner side of the center column 52. There are multiple air holes 56 and straight tubes 57, and there is a one-to-one correspondence between the air holes 56 and the straight tubes 57. This arrangement facilitates the subsequent squeezing of air in the sealing shell 55 into the flexible tube 81.

[0042] As a further technical solution for implementing this solution, the cross section of the piston block 53 is annular. The interior of the piston block 53 is slidably connected to the outside of the center column 52 via a sealing ring. The exterior of the piston block 53 is slidably connected to the inner wall of the sealing shell 55 via a sealing ring. The fixed circular plate 51, the center column 52, the piston block 53, and the sealing shell 55 are coaxially arranged. Through the above arrangement, the sealing between the piston block 53 and the sealing shell 55 can be ensured, and the stability of the piston block 53 during movement can be ensured.

[0043] As a further technical solution of this solution, there is a one-to-one correspondence between the straight tube 57 and the auxiliary reset unit 8. The auxiliary reset unit 8 includes a flexible tube 81. An elastic spring 83 is installed on the inner side of the bottom end of the flexible tube 81, and a clamping block 82 is installed on the outer side of the bottom end of the flexible tube 81. Through this arrangement, the flexible tube 81 can be stably connected to the first rotating rod 61 and the second rotating rod 63.

[0044] As a further technical solution for implementing this solution, two clamping blocks 82 are provided inside each auxiliary reset unit 8. The two clamping blocks 82 are fixedly connected to the first rotating rod 61 and the second rotating rod 63 respectively. The flexible tube 81 is open at one end, and the open end of the flexible tube 81 is fixedly connected to the straight tube 57. The elastic spring 83 is provided between the two clamping blocks 82. Through this arrangement, the deformation of the flexible tube 81 is conveniently utilized to later expand the first rotating rod 61 and the second rotating rod 63.

[0045] As a further technical solution of this solution, multiple upper connecting seats 9 and bottom connecting seats 10 are provided, and the upper connecting seats 9 and the bottom connecting seats 10 correspond one to one. The upper connecting seat 9 is rotatably connected to the first rotating shaft 62, and the bottom connecting seat 10 is rotatably connected to the second rotating shaft 64. Through the above arrangement, the first rotating rod 61 and the second rotating rod 63 can be stably limited.

[0046] As a technical solution for further implementation of this scheme, the buoyancy ring plate 7 is slidably connected to the upper end of the pump body 11 and the positioning cover shell 2, and the interior of the buoyancy ring plate 7 is hollow. The above setting can further improve the stability of the entire device during use.

[0047] Workflow: When irrigating a small area of ​​farmland through a well, first, the DC water pump 1 is placed into the well through the pull rope 3. During the placement process, it is necessary to connect it to the DC water cup pump 1 through an electric wire, and at the same time, the irrigation glue pipe is connected to the drain outlet 13. During the placement process, the buoyancy ring plate 7, the positioning unit and the fixing frame 5 can effectively prevent the DC water pump 1 from shaking and colliding with the well wall, and can protect the shell of the DC water pump 1;

[0048] When the DC water pump 1 completely enters the water source inside the well, the buoyancy ring plate 7 will move upward under the influence of buoyancy and exceed the pump body 11. During the upward movement of the buoyancy ring plate 7, the first rotating rod 61 and the second rotating rod 63 will be controlled to rotate, and the damping member 65 will be controlled to move in a direction away from the center point of the DC water pump 1. When the damping member 65 contacts the inner wall of the well, it stops moving, thereby positioning the DC water pump 1. This setting can enable the DC water pump 1 to completely enter the water source to pump water during the operation of the DC water pump 1, and at the same time can reduce the swing amplitude of the DC water pump 1 during the pumping process, thereby effectively improving the stability of the DC water pump 1 during the pumping process.

[0049] After the irrigation is completed, the power supply is stopped and the DC water pump 1 is pulled out of the well by pulling the rope. During the upward movement of the DC water pump 1, the positioning cover 2 will contact the piston block 53. If the damping member 65 is in close contact with the well wall, the piston block 53 will squeeze the air inside the sealing shell 55 into the inside of each flexible tube 81 during the pulling process. After the air is squeezed into the flexible tube 81, the first rotating rod 61 and the second rotating rod 63 can be stretched apart, thereby facilitating the entire device to be lifted out of the well, which is very convenient.
