Description
Technical Field
The invention relates to the technical field of agriculture, in particular to a hydraulic-driven automatic drainage system for farmlands in hilly areas.
Background
The rainfall capacity of autumn forest areas in China is quite sufficient, so that the crop rice is planted in hilly areas, but the requirement of the rice on the water level is very high, and the requirement of the rice on the water quantity at each stage is also very high. Every time of heavy rain, the farmland always accumulates a lot of water, which causes rice to be submerged and the yield to be reduced. At the moment, farmers excavate the channel to drain water, and the channel must be filled after the water is drained to the water level suitable for rice growth, so that the original appearance of the field is restored.
Currently, some problems still exist in farmland drainage, such as: lack of farmland water level monitoring systems or inadequate monitoring; the drainage is not timely. Due to the large difference of rainfall in seasonality and space, when sudden rainstorm and waterlogging frequently occur, the field often has a hysteresis effect in the drainage process; because of the influence brought by some traditional agricultural development ideas, agricultural management personnel in many places pay more attention to the agricultural irrigation problem, and do not deeply discuss the drainage problem, so that the position of the farmland drainage project is more unfavorable.

Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1 and 3: the invention comprises a buoy groove 2, a buoy 3, a straight rod 4, a latch connecting structure 5, a copper sheet plug 6, a drain pipe 7, a water inlet 8, a through hole 10, a gravity square buoy 11, a rope 12 and a gate 13, wherein the buoy groove 2 is positioned on a ground plane 1, the lower end of the buoy groove 2 is provided with the water inlet 8, the buoy 3 is positioned in the buoy groove 2, one side of the upper end of the buoy 3 is detachably connected with the straight rod 4 through the latch connecting structure 5, the straight rod 4 is positioned in the through hole 10, the lower end of the straight rod 4 is positioned in the drain pipe 7 below the ground plane 1, the lower end and the middle section of the straight rod 4 are both fixedly provided with the copper sheet plug 6, the copper sheet plug 6 at the lower end of the straight rod 4 is used for opening and closing the drain pipe 7, the copper sheet plug 6 of the straight rod 4 is used for opening and closing the through, and is communicated with the drain pipe 7, the gravity square buoy 11 is connected with the upper end of the gate 13 through the rope 12 connected with a pulley.
As an improvement, an extension tube 9 is sleeved between the outside of the straight rod 4 and the drain pipe 7.
As shown in fig. 2: the clamp tooth connecting structure is composed of a straight rod clamp tooth and a buoy clamp tooth, the straight rod clamp tooth is located on the outer wall of the straight rod, the buoy clamp tooth is arranged on one side of the buoy, and the straight rod clamp tooth is located in the buoy clamp tooth and clamped.
Preferably, the straight rod latch and the buoy latch are both arc-shaped.
The working principle of the invention is as follows:
when the water level exceeds the required water level: the buoy rises, the straight rod connected with the buoy also rises to drive the upper copper sheet plug to move upwards to block the through hole, the lower copper sheet plug also moves upwards, the drain pipe is opened, the water level of the vertical shaft falls, the gravity square buoy falls, and the gate correspondingly rises to open water.
When the water level drops to the required water level: the buoy descends, the straight rod and the copper sheet plug also descend, so that the upper through hole is opened, the drain pipe is closed, the vertical shaft starts to feed water until the gravity square buoy ascends, the gate descends and is closed, and the effect is finished.
The water level can be adjusted at different periods by the latch connecting structure, the copper sheet plug, the gravity buoy and the gate. The buoy is used for detecting whether the water level exceeds the required water level height or not, and has the specific function of driving the straight rod sleeved on the buoy. The straight rod and the upper and lower copper sheet plugs directly act, the upper and lower copper sheet plugs are driven by the ascending and descending of the buoy, and the water level height in the vertical shaft is adjusted. The clamping grooves and the clamping teeth are connected between the two clamping grooves, so that the relative distance can be adjusted, and the problem of different optimal heights in different periods can be solved. The straight rod of the latch is 33cm long and 0.3cm in radius. The buoy radius is 3.2cm and height is 6 cm. The materials are all pp plastics.
The drain pipe is positioned at the lower part of the vertical shaft, and the pipe opening drains water towards the outer side of the rice field. The copper sheet plug is connected on the straight rod. When the water level in the field is normal, the upper copper sheet plug is separated from the through hole, and the lower copper sheet plug is directly pressed on the drain pipe, so that the water quantity in the vertical shaft is large. When the water level in the field is too high, the through hole is tightly attached to the upper copper sheet plug, and the lower copper sheet plug is away from the drainage pipe opening by a certain distance, so that the water level of the vertical shaft is lowered. The waterproof telescopic sleeve is connected with the drain pipe and mainly prevents water from entering the drain pipe from the upper part, the straight rod is arranged in the telescopic sleeve, the upper part of the sleeve can be stretched, and the part connected with the drain pipe cannot be stretched. The distance between the drainage pipe and the bottom of the vertical shaft is 0.5cm, the length is 22.8cm, the width is 4cm, and the height is 2.2 cm. The upper copper sheet plug and the lower copper sheet plug are respectively 0.8cm away from the upper water inlet and the water outlet of the water drainage pipe. The copper sheet plug has a radius of 1.5cm and a thickness of 0.2 cm. The length of the telescopic sleeve is 2cm, the outer diameter is 0.8cm, and the inner diameter is 0.3 cm.
The vertical shaft is positioned at the lower part of the whole device, the upper part of the vertical shaft is connected with the upper half part of the vertical shaft through a through hole, the lower part of the vertical shaft is connected with a square drainage pipe, and the inside of the vertical shaft is a gravity square buoy. The through hole and the square drain pipe are connected with the upper copper sheet plug and the lower copper sheet plug. The floating pontoon has a large weight, but can rise in water by self buoyancy, so the floating pontoon rises and falls in the vertical shaft by the rise and fall of the water level in the vertical shaft. The buoys are connected with the gate through thin ropes through pulleys, and the total weight of the buoys on the left side and the right side is larger than the weight of the gate. When the water level in the vertical shaft descends, the buoy descends to lift the gate, the water level of the vertical shaft ascends, the buoy ascends, and the gate can descend by means of the self weight, so that the function of automatic drainage is realized. The experimental gate is 0.5cm in thickness, 30cm in length and 15cm in height, is made of organic glass and has the density of 1.180g/cm 3. The gravity square buoy is 15cm long, 25cm wide and 10cm high, and has an average density of 0.544g/cm 3.
