Description

Technical Field

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

[0002] A farmland water conservancy irrigation device is a device or system used to convey and distribute irrigation water to farmland. It channels water from water sources (such as rivers, reservoirs, groundwater, etc.) to farmland through components such as pipelines, channels, and sprinkler heads to meet the water requirements for crop growth.

[0003] Common irrigation methods include drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and traditional flood irrigation. Drip irrigation technology directly delivers water drop by drop to the roots of crops through drip emitters, which is water-saving and efficient. Sprinkler irrigation uses sprinkler heads to spray water into small water droplets to evenly cover the farmland. These devices not only improve irrigation efficiency but also reduce water resource waste, which is of great significance for ensuring food security and the sustainable development of agriculture.

[0004] During the irrigation of small areas of farmland, generally, a DC water pump is used for irrigation. When the DC water pump is lowered into a well through a pull rope, if the placement depth is relatively large, it will cause the problem that the DC water pump collides with the well wall. Moreover, the distance between the fixed end on the upper side of the pull rope and the DC water pump is too large, resulting in a large swing amplitude of the DC water pump, affecting the stability of the DC water pump operation. Therefore, a farmland water conservancy irrigation device is proposed to solve the above problems. Summary of the Invention

Through the above arrangement, the flexible tube 81 can be stably connected with the first rotating rod 61 and the second rotating rod 63.

[0044] As a technical solution for further implementation of the present invention, two blocks 82 are provided inside any auxiliary reset unit 8, and the two blocks 82 are respectively fixedly connected to the first rotating rod 61 and the second rotating rod 63.

[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 arrangement can further improve the stability of the entire device during use.

[0047] Workflow: When a small area of ​​farmland is irrigated through a well, the DC water pump 1 is first placed into the well through the pull rope 3. During the placement process, it is necessary to connect the DC water pump 1 with the DC water cup pump 1 through an electric wire, and at the same time, the irrigation glue pipe is connected to the drain port 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 the housing of the DC water pump 1 can be protected;

[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 allows 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 reduces the swing amplitude of the DC water pump 1 during the pumping process, effectively improving the stability of the DC water pump 1 during the pumping process.

[0049] After 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 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 overall lifting of the device from the well, which is very convenient.

[0050] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
