Description

Technical Field

[0001] The invention relates to the technical field of farmland water-saving irrigation, and in particular to a high-efficiency and energy-saving farmland irrigation device and method. Background Art

[0002] In farmland irrigation, water-saving irrigation technology plays a vital role. This technology is based on the actual water demand at each stage of the crop growth cycle. By precisely controlling the moisture content of the soil root layer or the appropriate water depth in the farmland, the irrigation time, frequency and specific irrigation amount are scientifically arranged to maximize the use of water resources. However, in actual operation, especially in outdoor farmland environments, the following problems still exist: On the one hand, large-scale canal water sources are not available in all farmland areas, especially in areas far away from natural water bodies such as rivers and lakes. Farmland irrigation often relies on scattered water sources such as wild ponds and small ditches. Although these water sources can provide the necessary irrigation water, their utilization efficiency is generally low because of the lack of efficient water collection, purification and distribution systems, resulting in serious waste of water resources and low water resource utilization.

[0003] On the other hand, when water is pumped from such natural water bodies for irrigation, the water bodies often contain more impurities, such as silt, plankton, fallen leaves and plastic waste, and the water quality is poor. These impurities will not only reduce the efficiency of the pumping equipment and increase energy consumption, but may also cause wear and tear on the pumping equipment due to long-term accumulation, shortening its service life.

[0004] In addition, using water containing impurities directly for irrigation may also affect the growth environment of crops, such as blocking soil pores, reducing soil permeability and water retention capacity, and thus having an adverse effect on the growth of crops. Summary of the invention

[0005] The purpose of the present invention is to provide an efficient and energy-saving farm irrigation device and method to solve the problem of low water pumping efficiency of the farm irrigation device mentioned in the above background technology. An efficient and energy-saving farm irrigation device and method that can effectively utilize scattered water sources, effectively filter impurities, protect pumping equipment, and meet the needs of water-saving irrigation is particularly important. The present invention is proposed based on this background, aiming to solve the above technical problems and improve the efficiency and sustainability of farm irrigation.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an efficient and energy-saving farm irrigation device, comprising a base, the base is in a Z shape, a water pump is arranged on one end of the base, the water inlet of the water pump is connected to a pumping component, the water outlet of the water pump is connected to a centrifugal filter through a water pipe, and the centrifugal filter is also provided with a filter outlet for connecting an external irrigation pipeline; a sewage outlet is arranged at the bottom of the centrifugal filter for discharging sand and soil filtered by the centrifugal filter, a storage battery is arranged under the other end of the base, and a solar panel is arranged on the base above the storage battery; The pumping component includes a float plate, which is used to adapt to different water depths so that the pumping component can float on the surface of the water body.

At this time, the floating plate floats above the water surface, the sliding plate mechanism is on the water surface, and the filtering water collection bin sinks below the water surface to filter the water source; S2. When the pumping component is placed, the telescopic motor starts to drive the second slider and the sliding plate mechanism connected to it to start working. The sliding plate slides back and forth in the slide groove to remove impurities on the surface of the water body and prevent them from entering the filter water collection bin; At the same time, the cutting mechanism starts synchronously, and the spiral rod moves through the movement of the second slider, driving the spiral sleeve and the rotating blade on its outer side to rotate and cut and clean the weeds in the water above the filter water collection bin to ensure the cleanliness of the water source; The filter water collection tank collects the initially cleaned water through the filter holes on it, further filters impurities through the filter screen, and then transports the water to the water pump through the pump pipe; S3, after the water pump receives the clean water from the filter water collection tank, it is transported to the centrifugal filter through the water pipe for filtration, and then irrigates from the filter outlet through the external irrigation pipe; The water level sensor on the float continuously monitors the water level. When the water level is detected to be too low and affects the normal operation of the pumping components, the water level sensor will send a signal to control the start of a small screw propeller, driving the float to move along the water surface to other water level areas to maintain an appropriate floating position.

[0023] A method for using an efficient and energy-saving farmland irrigation device comprises the following steps: S1. Put the pumping component 3 as a whole into a natural water body and move the pumping component 3 to a pre-selected position. At this time, the floating plate 31 floats above the water surface, the sliding plate mechanism 32 is on the water surface, and the filtering water collection chamber 33 sinks below the water surface to filter the water source; S2, when the pumping component 3 is placed, the telescopic motor starts, driving the second slider 325 and the sliding plate mechanism 32 connected thereto to start working, and the sliding plate 322 slides back and forth in the chute to remove impurities on the surface of the water body and prevent them from entering the filtering water collection bin 33; At the same time, the cutting mechanism 34 is synchronously started, and the spiral rod 342 moves through the movement of the second slider 325, driving the spiral sleeve 346 and the rotating blade 344 on its outer side to rotate and cut and clean the weeds in the water body above the filter water collection bin 33, ensuring the cleanliness of the water source; The filter water collection tank 33 collects the preliminarily cleaned water through the filter holes 331 thereon, further filters impurities through the filter net 332, and then transports the water to the water pump 2 through the pumping pipe 35; S3, after the water pump 2 receives the clean water from the filter water collection tank 33, it is transported to the centrifugal filter 4 through the water pipe 21 for filtration, and then irrigates from the filter outlet 41 through the external irrigation pipe; The water level sensor on the floating plate 31 continuously monitors the water level height. When the water level is detected to be too low, affecting the normal operation of the pumping component 3, the water level sensor will send a signal to control the start of the small screw propeller, driving the floating plate 31 to move along the water surface to other water level areas to maintain an appropriate floating position.

[0024] Working principle: Solar panels 6 are provided on the base 1 and the floating plate 31. These solar panels can convert sunlight into electrical energy and store it in the battery 5 under the base 1. The battery 5 provides power for the entire device. The filter water collection tank 33 under the pumping component 3 collects and preliminarily filters the water source through the filter holes 331 and the filter net 332 thereon. The sliding plate mechanism 32 is connected to the telescopic motor through the second slider 325, and slides back and forth on the water surface below the floating plate 31. The second slider 325 drives the rotating column 324 to move back and forth, thereby driving the two first sliders 323 to move back and forth respectively. The two first sliders 323 move in their respective slide grooves, driving their respective sliding plates 322 to swing back and forth crosswise, thereby removing impurities such as leaves, plastics, etc. on the surface of the water body.
