Description

Technical Field

[0001] The utility model relates to the technical field of farmland irrigation and drainage equipment, in particular to a farmland water conservancy circulation irrigation and drainage device. Background Art

[0002] Agricultural irrigation mainly refers to irrigation operations in agricultural cultivation areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation and ordinary sprinkler irrigation. Traditional surface irrigation includes furrow irrigation, furrow irrigation, flooding irrigation and overspray irrigation. Water storage wells are set up in the soil, and corresponding soil ditches are dug at the same time. During the rainy season, excessive water in the farmland enters the water storage well to collect rainwater and avoid the water level from being too high to submerge crops. During droughts, water pumps are used to pump water out of the water storage well to irrigate crops to improve the utilization rate of water resources. However, the traditional water pump extends the pipe into the water storage well, and the installation position of the water inlet at the bottom of the pipe is determined. However, when collecting rainwater in the field, a certain amount of sediment will enter the water storage well, and the sediment will accumulate at the bottom of the water storage well, which will easily cause the pipe inlet to be blocked in the later stage. Based on this, a farmland water conservancy circulation irrigation and drainage device is proposed to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a farmland water conservancy circulation irrigation and drainage device, which effectively solves the deficiencies of the prior art.

The float in this scheme facilitates the pushing of the connecting rod and the indicator block through its own buoyancy, thereby facilitating intuitive observation of the water level changes inside the water storage well. At the same time, in order to ensure that the indicator block can be observed by the user, a reflective sticker can be attached to the outer wall of the indicator block, or the LED indicator light can be adjusted to facilitate marking the user at night.

[0007] Preferably, any of the above schemes is that a filter screen is provided inside the multiple water inlets, and operating handles are provided on both sides of the top surfaces of the multiple filter screens. This scheme allows users to quickly disassemble and install the filter screens through the operating handles to clean impurities in the filter screens. At the same time, the multiple water inlets are connected to the earth ditches in the field, so that rainwater can enter the interior of the water inlets along the earth ditches, thereby facilitating the storage of rainwater in the water storage well.

[0008] Preferably, any of the above schemes is that a plurality of the auxiliary airbags are evenly distributed on the outer wall of the water inlet pipe. By using this scheme, it is convenient to horizontally support the water inlet pipe near one end of the annular airbag, thereby avoiding the annular airbag from tilting due to the gravity of the water inlet pipe, thereby ensuring that the water inlet pipe draws rainwater from inside the water storage well.

[0009] Preferably, any of the above schemes is that a transparent window is embedded in the middle of the closing plate, and one side of the closing plate is fixed to one side of the manhole by a lock. This scheme facilitates locking and fixing the closing plate by the lock to prevent children from accidentally opening the closing plate and causing unnecessary danger.

At the same time, multiple water inlets 2 are installed on the top of one side of the water storage well 1, so that in the rainy season, rainwater enters the water storage well 1 along the field ditches and multiple water inlets 2. An annular airbag 16 is set up, which is connected to the end of the water inlet pipe 12. At the same time, multiple auxiliary airbags 13 are set on the outer wall of the water inlet pipe 12, and then the annular airbag 16 and the auxiliary airbag 16 lift the pipeline to the liquid level, so as to avoid the accumulation of mud and sand inside the water storage well 1 and block the water inlet, thereby effectively solving the problems existing in the prior art, and then by setting a manhole 8.
