[0002] Farmland refers to the land used for agricultural production and is the place where crops grow; the soil quality, irrigation conditions, climate environment, etc. of the farmland will all affect the growth of crops.

[0003] When the climate environment is rainy, rainwater will continuously accumulate in the farmland. Once the amount of water in the farmland is too much, it will damage the crops in the farmland; at this time, in order to prevent the crops from being affected, a drainage pumping station is generally adopted to quickly pump out a large amount of accumulated water in the farmland and discharge it into rivers, lakes or other water bodies, so as to prevent or reduce the damage to the crops caused by excessive rainfall; therefore, the drainage pumping station is crucial for protecting the farmland from floods.

[0004] However, due to the large amount of silt and weeds in the farmland, and the accumulated water in the farmland contains pesticide components, once the drainage pumping station discharges the accumulated water in the farmland into rivers or lakes, it is easy to affect the water quality of the rivers or lakes.

In this embodiment, the filter net 44 is annular and is arranged in the annular cavity 411. An annular groove 412 is opened on the inner wall of the annular cavity 411, the annular plate 42 is arranged in the annular groove 412, and the annular plate 42 is fixedly sleeved on the filter net 44. The filter net 44 can filter out larger impurities such as silt and weeds in the accumulated water, so as to optimize the water quality of the accumulated water.

[0041] See Figure 3 , Figure 5 and Figure 6 , the net bag 45 is arranged in the transition pipe 31, and the net bag 45 is located on the side of the diversion plate 53 away from the driving rod 51; the activated carbon 46 is arranged in the net bag 45. When the accumulated water flows into the transition pipe 31, the accumulated water will pass through the activated carbon 46 to reduce the pesticide components in the accumulated water, so as to further optimize the water quality of the accumulated water. In this embodiment, a cover body (not shown in the figure) can be arranged on the transition pipe 31 to facilitate the replacement of the activated carbon 46.

[0048] See Figure 5 , the guiding ring 84 is fixed on the outer side wall of the first pipe 211, and the adjusting rope 82 passes through the guiding ring 84. The guiding ring 84 can limit the adjusting rope 82, so that the adjusting rope 82 is not easily shaken randomly. The floating ball 85 is fixed on the outer side wall of the fourth pipe 214. In this embodiment, a plurality of floating balls 85 are provided and are evenly distributed along the circumferential direction of the fourth pipe 214. With the arrangement of the floating balls 85, the fourth pipe 214 can be adjusted up and down according to the water level in the farmland; in application, when the adjusting rope 82 is completely released, if the adjusting rope 82 is in a taut state, the farmland can be replenished with water in time; If the station box 1 needs to be moved, the adjusting rope 82 is wound up. First, the fourth pipe 214 is completely pulled back into the first pipe 211; then, the adjusting rope 82 will pull the first pipe 211 to turn upwards to be close to the station box 1, so as to reduce the space occupied by the first pipe 211 and facilitate the movement of the station box 1.
