In this example, the procedure used in the present invention is as follows:
firstly, water in a river channel is pumped into the water channel seat 3 through the water pump, so that the water flows in the water channel seat 3, when the water flows in the water channel seat 3, part of the water flows through the water flow pipe 5, the other part of the water impacts the turbine fan blade 13 when the water flows outside the water flow pipe 5, then the turbine fan blade 13 rotates, the turbine fan blade 13 drives the rotating column 11 to rotate in the rotating process, then the plurality of push plates 12 are driven to rotate, when the push plates 12 rotate to a specified position, the bearing plate 16 is pushed, then the connecting rod 15 is driven to push the sealing plate 9 to pull the working spring 14, then the sealing plate is separated from the sliding groove 8 to move to the outlet of the water flow pipe 5, and the sealing work of the water flow pipe 5 is finished, because a large amount of water flows in the water flow pipe 5, the water in the water flow pipe 5 can generate great pressure under the effect of water hammer suddenly, then the water in the water flow pipe 5 can be squeezed into the drainage pipe 6 under the action of pressure, then the water enters the working box 4, then the water can enter a farmland through the irrigation hole 18, the plurality of push plates 12 can periodically push the bearing plate 16 in the rotating process, then the sealing plate 9 periodically completes the sealing work, then the water entering the water flow pipe 5 can continuously and periodically enter the working box 4 through the drainage pipe 6, and then the irrigation work is completed, so that the user is not required to perform the work of digging, communication and the like during the irrigation work, and the irrigation work of the user is greatly facilitated;
when water enters the working box 4 through the drainage tube 6 and then enters the farmland through the irrigation holes 18 for irrigation, the water level in the farmland and the working box 4 rises, so that the buoyancy plate 17 floats upwards under the buoyancy of the water, then after the water required by the farmland is filled, the rising water level can enable the buoyancy plate 17 to be attached to the drainage tube 6, so that the buoyancy plate 17 can complete the sealing work on the drainage tube 6 by virtue of the buoyancy of the water and the magnetic attraction between the first magnet 25 and the second magnet 27, so that the water in the water flow tube 5 can not enter the working box 4 through the drainage tube 6, thereby effectively avoiding the over-irrigation condition, greatly ensuring the irrigation quality of the farmland, simultaneously, as the buoyancy plate 17 rises, the pull rope 24 loses the pull force of the buoyancy plate 17 and can not pull the spring plate 22, the spring plate 22 can push the pull rod 21 under the elastic force of the contraction spring 23, then the sealing plug 20 is pushed to be separated from the pressure discharge hole 19, so that when water in the water flow pipe 5 enters the drainage pipe 6 again due to the water hammer effect, the water can be discharged back to the ditch seat 3 through the pressure discharge hole 19, the buoyancy plate 17 cannot be excessively squeezed, and the smooth operation of the sealing and blocking work is greatly ensured.
Example two
Referring to fig. 1, the difference between the first embodiment and the second embodiment lies in the arrangement of the supporting rod 29, the supporting rod 29 is fixedly connected to the upper end surface of the buoyancy plate 17, the supporting rod 29 is arranged close to the irrigation hole 18, the rotating rod 30 is rotatably connected to the supporting rod 29, the water flow fan 31 is fixedly connected to one end of the rotating rod 30 close to the irrigation hole 18, the water flow fan 31 is arranged in the irrigation hole 18, the upper end surface of the buoyancy plate 17 is rotatably connected to the rotating shaft 32, helical gears 33 are fixedly connected to both one end of the rotating shaft 32 away from the buoyancy plate 17 and one end of the rotating rod 30 away from the water flow fan 31, the two helical gears 33 are meshed with each other, the upper floating fan 34 is fixedly connected to one end of the rotating shaft 32 close to the buoyancy plate 17, the upper floating fan 34 can be better immersed in water by being arranged close to the buoyancy plate 17, so that the rotating, because the device sets up in the farmland, there is earth to exist in the work box 4, and the existence of earth can make the adhesion of buoyancy board 17 on the lower inner wall of work box 4, then make buoyancy board 17 unable smooth buoyancy effect at water rise under and accomplish the sealing work, such setting up make among the device when rivers through irrigating hole 18 discharge alright drive rivers flabellum 31 and rotate, then through dwang 30, two helical gears 33 and axis of rotation 32 drive the rotation of come-up flabellum 34, make the come-up flabellum 34 can be smooth drive axis of rotation 32 and buoyancy board 17 through rotating and rise, the effectual resistance that has overcome earth and probably bring, very big guarantee that the come-up that buoyancy board 17 can be smooth accomplishes the sealing work, then make the completion ration irrigation work that the device can be smooth, very big user's use of having made things convenient for.
By the device, when water in the work box 4 is discharged through the irrigation hole 18, flowing water can drive the water flow fan blades 31 in the irrigation hole 18 to rotate, the rotating water flow fan blades 31 can drive the rotating rod 30 to rotate, then the rotating shaft 32 is driven to rotate by the aid of the two bevel gears 33 arranged in a meshed mode, the rotating shaft 32 can drive the floating fan blades 34 to rotate in the rotating process, when the water level in the work box 4 rises to a certain height and the floating plate 17 cannot normally float upwards due to soil and the like, the floating fan blades 34 can drive the floating plate 17 soaked in the water to float upwards through rotation, then sealing work is smoothly completed, the situation that the floating plate 17 cannot float upwards at the bottom of the work box 4 due to adhesion of soil and the like in the field can be effectively avoided, smooth proceeding of sealing work is greatly guaranteed, and then quantitative irrigation work of a user can be smoothly completed, the use of the user is greatly facilitated.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
