Description

Technical Field

[0001] This utility model belongs to the field of plant irrigation technology, specifically relating to an intelligent irrigation device for water conservancy project management. Background Technology

[0002] Because plants are affected by wind during spray irrigation, the irrigation solution travels a greater distance when spraying with the wind than when spraying against the wind. Given this, even with water at the same pressure delivered to the nozzles, the sprayed area differs depending on the direction of travel, easily leading to missed areas or repeated spraying. Furthermore, spraying against the wind causes a loss of water kinetic energy, increasing energy consumption for spraying the same area. Utility Model Content

[0003] This utility model provides the following technical solution: including: a water storage module, a movable nozzle, a wind direction sensor, a wind resistance detector, and a variable pressure water pump;

[0004] The wind direction sensor detects the wind direction and controls the spray angle range through the direction-changing controller. The spray angle range is 90 degrees symmetrical about the wind direction. The wind resistance detector is installed on the opposite side of the spray direction of the movable nozzle. The wind resistance detector rotates as the spray angle of the movable nozzle changes. The pressure controller adjusts the delivery pressure of the pressure-changing water pump according to the pressure of the wind resistance detector. The detection pressure of the wind resistance detector is inversely proportional to the delivery pressure of the pressure-changing water pump. The pressure-changing water pump delivers the liquid in the water storage module to the movable nozzle for irrigation.

[0005] The movable nozzle includes a fixed device buried in the ground, a movable pipe, and a water delivery pipe. The water delivery pipe is located at the bottom of the fixed device. After passing through the ground, the water delivery pipe is connected to the variable pressure water pump and the water storage module. The movable pipe and the water delivery pipe are sealed together by a dynamic sealing ring.

[0006] The fixture has a reversing controller inside, and a drive gear is fixedly connected to the outside of the movable tube. The reversing controller is connected to the drive gear and drives the movable tube to rotate.

[0007] The spray pipe is fixedly connected to the side of the movable pipe and exposed outside the fixture. The voltage regulator is installed outside the movable pipe and located directly behind the spray pipe.

[0008] The wind resistance detector consists of a movable block, a spring, and a pressure sensor. A groove is formed on the outside of the movable tube to accommodate the movable block. The pressure sensor is installed inside the groove. The spring is located between the movable block and the pressure sensor. The variable pressure controller controls the delivery water pressure of the variable pressure water pump based on the data transmitted by the pressure sensor.

[0009] The wind resistance detector consists of a diaphragm, a cavity, a pipe, and a piston. The cavity is located outside the movable tube, and the open end of the cavity is closed by the diaphragm. The movable tube is equipped with a pipe that communicates with the cavity, and a piston and a distance sensor are installed inside the pipe. The variable pressure controller controls the water pressure delivered by the variable pressure water pump based on the data transmitted by the distance sensor.

[0010] The beneficial effects of this utility model are:

[0011] When the spray direction of the movable nozzle is aligned with the wind direction, the pressure regulator is in the windward position, and the wind pressure on the pressure regulator is at its maximum. At this time, the delivery pressure of the pressure regulator can be reduced according to the pressure of the pressure regulator, making full use of the wind's assist effect for long-distance delivery. As the angle of the movable nozzle changes, the pressure detected by the pressure regulator gradually decreases until it stops. When the spray angle of the movable nozzle is perpendicular to the wind direction, the wind resistance pressure obtained by the pressure regulator is minimal or even disappears. During the rotation, the pressure of the water delivery pipe gradually increases, thereby reducing the deflection effect caused by the wind. This process reduces kinetic energy loss, makes full use of wind energy, and avoids the problem of the liquid coverage area being affected by the wind, resulting in excessive flight distance.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-6 The present invention provides the following technical solution: including: a water storage module 1, a movable nozzle 2, a wind direction sensor 3, a wind resistance detector 4, and a variable pressure water pump 5;

[0021] The wind direction sensor 3 detects the wind direction and controls the spray angle range through the direction change controller 24. The spray angle range is 90 degrees symmetrical about the wind direction. The wind resistance detector 4 is installed on the opposite side of the spray direction of the movable nozzle 2. The wind resistance detector 4 rotates as the spray angle of the movable nozzle 2 changes. The pressure controller 6 adjusts the delivery pressure of the pressure pump 5 according to the pressure of the pressure detector 4. The detection pressure of the pressure detector 4 is inversely proportional to the delivery pressure of the pressure pump 5. The pressure pump 5 delivers the liquid in the water storage module 1 to the movable nozzle 2 for irrigation.

[0022] In this implementation plan: the water storage module 1 is a water tank, which stores liquid. The wind resistance detector 4 can be installed on the top of the water storage module 1. The wind resistance detector 4 detects the wind direction. Since the wind direction changes throughout the day, the entire spraying process is dynamic spraying.

[0023] First, the angle of the movable nozzle 2 can change. The movable nozzle 2 is controlled and driven by the direction change controller 24 and the drive gear 221. After the wind direction sensor 3 detects the wind direction information, the information of the wind direction sensor 3 is converted into the drive parameters of the direction change controller 24 through any data processing method such as computer or controller. The direction change controller 24 controls the drive gear 221 to rotate so that the spray direction of the movable nozzle 2 corresponds to that of the wind direction sensor 3. This method is existing technology and will not be described in detail here.

[0024] First, when the spray direction of the movable nozzle 2 is aligned with the wind direction, the pressure controller 6 is in the windward state, and the wind pressure on the pressure controller 6 is at its maximum. At this time, the delivery pressure of the pressure pump 5 can be reduced according to the pressure of the pressure controller 6, making full use of the wind's assist effect for long-distance delivery. As the angle of the movable nozzle 2 changes, the detection pressure of the pressure controller 6 gradually decreases until it stops. When the spray angle of the movable nozzle 2 is perpendicular to the wind direction, the wind resistance pressure obtained by the pressure controller 6 is minimal or even disappears. During the rotation, the pressure of the water delivery pipe 25 gradually increases, thereby reducing the deflection effect caused by the wind. This process reduces kinetic energy loss, makes full use of wind energy, and avoids the problem of excessive flight distance caused by the influence of wind on the liquid coverage area.

[0025] The movable sprinkler head 2 includes a fixing device 21 buried in the ground, a movable pipe 22, and a water delivery pipe 25. The water delivery pipe 25 is located at the bottom of the fixing device 21. After passing through the ground, the water delivery pipe 25 is connected to the variable pressure water pump 5 and the water storage module 1. The movable pipe 22 and the water delivery pipe 25 are sealed together by a dynamic sealing ring. The water delivery pipe 25 is connected to the water storage module 1, and the variable pressure water pump 5 draws the liquid inside the water storage module 1 into the water delivery pipe 25 and into the movable pipe 22, which can then be moved.

[0026] The fixing device 21 is equipped with a reversing controller 24, and the movable tube 22 is fixedly connected to the outside of the drive gear 221. The reversing controller 24 is connected to the drive gear 221 for transmission, and the reversing controller 24 drives the movable tube 22 to rotate.

[0027] The reversing controller 24 is a motor. The motor drives the gear and the drive gear 221 to rotate the movable tube 22. The dynamic sealing ring can be a sealing ring made of rubber and Teflon, which can prevent leakage at the sliding point during rotation.

[0028] The spray pipe 23 is fixedly connected to the side of the movable pipe 22, and the spray pipe 23 is exposed outside the fixture 21. The transformer controller 6 is installed outside the movable pipe 22 and is located directly behind the spray pipe 23.

[0029] The transformer controller 6 is mainly used to receive the pressure from the frontal wind, thereby obtaining the wind force. Based on the wind force, the spray angle of the spray pipe 23 can be controlled. When the spray pipe 23 changes, the angle between the transformer controller 6 and the wind changes, and the pressure of the wind on the transformer controller 6 gradually decreases. At this time, the positive influence of the wind on the movement of the liquid is reduced, so the transformer pump 5 is in a pressurization state.

[0030] The wind resistance detector 4 consists of a movable block, a spring, and a pressure sensor. A groove for receiving the movable block is opened on the outside of the movable tube 22. The pressure sensor is installed inside the groove. The spring is located between the movable block and the pressure sensor. The transformer controller 6 controls the delivery water pressure of the transformer water pump 5 based on the data transmitted by the pressure sensor.

[0031] In areas with strong winds, the wind speed obtained by using a movable block in conjunction with a spring is more prone to change. When strong winds are applied to the movable block, the spring undergoes elastic deformation, which affects the value obtained by the pressure sensor. The value obtained by the pressure sensor, in turn, affects the delivery pressure of the variable pressure pump 5.

[0032] The wind resistance detector 4 consists of a membrane, a cavity, a pipe, and a piston. The cavity is located outside the movable tube 22, and the open end of the cavity is closed by the membrane. The movable tube 22 is equipped with a pipe that communicates with the cavity, and a piston and a distance sensor are installed inside the pipe. The variable pressure controller 6 controls the water pressure of the variable pressure pump 5 based on the data transmitted by the distance sensor.

[0033] For areas with low wind speeds, a thin-film structure is used. The thin film is elastic. When wind acts on the thin film, it contracts, increasing the pressure inside the cavity. This pressure drives the piston to move. The pressure is obtained through a distance sensor. The smaller the distance obtained by the distance sensor, the stronger the wind. The stronger the wind, the lower the pressure of the liquid being transported.

[0034] In practice, if the angle of rotation of the movable pipe 22 is too large in a single operation, it may cause area coverage problems. The rotation angle of the movable pipe 22 can be reduced in a single operation. For example, the angle can be greater than 0 degrees and less than 90 degrees, taking the wind direction as the starting point. If the wind direction remains fixed, counter-wind operation can be used. Under counter-wind operation, when the value collected by the transformer controller 6 is 0 degrees and the rotation continues, the pressure gradually increases until it reaches 90 degrees, at which point the water pressure corresponds to the highest pressure collected by the transformer controller 6.
