DETAILED DESCRIPTION
[0031] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.
[0032] Example 1, reference Figure 1-Figure 3, a watering control device for water conservancy construction, comprising a water pump 9 and two fixed frames 2, a water outlet 8 is arranged on the top of the water pump 9, and a water inlet 10 is arranged at one end of the water pump 9, a main pipe 1 is fixedly connected between the two fixed frames 2, and a telescopic pipe 7 is connected between the outer wall of one side of the main pipe 1 and the water outlet 8, a plurality of branch pipes 4 are connected to the outer wall of the other side of the main pipe 1 at equal distances, and a plurality of drip irrigation pipes 6 are connected to the outer wall of the bottom of each branch pipe 4 at equal distances, a bell mouth 13 is arranged at the connection between the drip irrigation pipe 6 and the branch pipe 4, and the narrow mouth of the bell mouth 13 faces the inside of the branch pipe 4, a limiting flow ball 15 is arranged inside the bell mouth 13, and a hook spring 16 is arranged between the outer walls on both sides of the bottom of the limiting flow ball 15 and the inner wall of the drip irrigation pipe 6, a pulling mechanism is arranged inside each branch pipe 4, and the same driving mechanism is arranged on one side of the plurality of pulling mechanisms, when it is necessary to irrigate the crops, the water pump 9 will extract water resources from the outside through the water inlet 10, and then through the outlet The water end 8 and the telescopic tube 7 transport water to the main pipe 1, and then the water in the main pipe 1 will flow into each branch pipe 4, and finally enter the drip irrigation pipe 6 at the bottom of each branch pipe 4, and flow out from the drip irrigation pipe 6 to drip irrigate the crops. In this process, if the amount of water flowing out of the drip irrigation pipe 6 is large, the driving mechanism is started, and the driving mechanism can make the flow-limiting ball 15 in each drip irrigation pipe 6 close to the corresponding bell mouth 13 through the pulling mechanism, so that the gap between the flow-limiting ball 15 and the bell mouth 13 becomes smaller, resulting in a decrease in the amount of water entering the drip irrigation pipe 6 from the branch pipe 4, and the hook spring 16 is stretched at this time; and if the amount of water flowing out of the drip irrigation pipe 6 is small, the driving mechanism resets the pulling mechanism, so that the gap between the flow-limiting ball 15 and the bell mouth 13 becomes larger, resulting in an increase in the amount of water entering the drip irrigation pipe 6 from the branch pipe 4, so that the amount of water flowing out of the drip irrigation pipe 6 can be controlled and adjusted, which greatly saves water resources and is suitable for irrigation of crops in different environments.
[0033] As a further solution of the present invention, the driving mechanism includes a worm 5, which is rotatably connected between the two fixing frames 2, and a driving motor 3 is provided at one end of the worm 5, and the driving motor 3 can rotate the worm 5 connected thereto.
[0034] As a further solution in the present invention, the pulling mechanism includes a rotating shaft 12, which is sealed and rotatably connected to the outer wall of one side of the branch pipe 4, and the outer wall of one side of the rotating shaft 12 is rotatably connected to the inner wall of the main pipe 1, and the outer wall of the other side of the rotating shaft 12 is fixedly connected to a turbine 11, the turbine 11 is engaged with the worm 5, and a traction rope 14 is fixedly connected between the rotating shaft 12 and the limiting ball 15. Because the turbine 11 on the rotating shaft 12 is engaged with the worm 5, when the worm 5 rotates forward, the rotating shaft 12 can rotate synchronously, and when the rotating shaft 12 rotates, the traction rope 14 can be wound around the outer wall of the rotating shaft 12, and when the worm 5 reverses under the action of the driving motor 3, the traction rope 14 wound around the outer wall of the rotating shaft 12 can be dispersed.
[0035] Working principle: When it is necessary to irrigate the crops, the water pump 9 will extract water resources from the outside through the water inlet end 10, and then transport the water to the main pipe 1 through the water outlet end 8 and the telescopic pipe 7. Then the water in the main pipe 1 will flow into each branch pipe 4, and finally enter the drip irrigation pipe 6 at the bottom of each branch pipe 4, and flow out from the drip irrigation pipe 6 to drip irrigate the crops. In this process, if the amount of water flowing out of the drip irrigation pipe 6 is large, the driving mechanism is started, and the driving motor 3 can make the worm 5 connected thereto rotate forward. Because the turbine 11 on the rotating shaft 12 is meshed with the worm 5, when the worm 5 rotates forward, the rotating shaft 12 can be rotated synchronously. When the rotating shaft 12 rotates, the traction rope 14 can be wound around the outer wall of the rotating shaft 12, which can make each The flow-limiting ball 15 in each drip irrigation pipe 6 is close to the corresponding bell mouth 13, so that the gap between the flow-limiting ball 15 and the bell mouth 13 becomes smaller, resulting in a decrease in the amount of water entering the branch pipe 4 into the drip irrigation pipe 6, and the hook spring 16 is stretched at this time; if the amount of water flowing out of the drip irrigation pipe 6 is small, when the worm 5 is reversed under the action of the driving motor 3, the traction rope 14 wound on the outer wall of the rotating shaft 12 can be dispersed, so that under the action of the rebound force of the hook spring 16, the flow-limiting ball 15 moves downward, and the gap between the flow-limiting ball 15 and the bell mouth 13 becomes larger, resulting in an increase in the amount of water entering the branch pipe 4 into the drip irrigation pipe 6, so that the amount of water flowing out of the drip irrigation pipe 6 can be controlled and regulated, which greatly saves water resources and is suitable for irrigation of crops in different environments.

[0038] As a further solution in the present invention, a delivery pipe 25 is provided directly above each airbag 18, and the delivery pipe 25 is fixedly connected to the top outer wall of the fixed plate 17, the air outlet end of the airbag 18 is connected to the delivery pipe 25, and a nozzle 26 is provided on the outer wall of one side of the bottom of the delivery pipe 25, the nozzle 26 is directly opposite to the meshing position of the worm 5 and the turbine 11, and the squeezed gas will enter the delivery pipe 25, and then be ejected through the nozzle 26 at the bottom of the delivery pipe 25, so that the meshing position of the worm 5 and the turbine 11 can be purged and cleaned to avoid the occurrence of jamming caused by residual garbage and impurity particles.
[0039] Working principle: When the worm 5 rotates, it will drive the cam 20 on its outer wall to rotate synchronously. In this process, the cam 20 will contact the push plate 21 on the extrusion plate 19 and apply force to it, so that the extrusion plate 19 will be close to the fixed plate 17.

The squeezed gas will enter the delivery pipe 25 and then be ejected through the nozzle 26 at the bottom of the delivery pipe 25. Because the nozzle 26 is facing the meshing position of the worm 5 and the turbine 11, the gas ejected from the nozzle 26 can purge and clean the meshing position of the worm 5 and the turbine 11 to avoid the occurrence of jamming caused by residual garbage and impurity particles.
