Description

Technical Field

[0001] The invention relates to an aquatic crop irrigation control valve, in particular to an interconnected metering ball valve type valve port integrated with remote monitoring. Background Art

[0002] At present, there are two main automatic valves for water supply control in rice fields. One is the float valve. In order to save water resources, shallow irrigation is generally used to supply rice growth. The float on the float valve body is in the shallow water area, which makes it difficult to play a buoyant role and cannot accurately control the water level in the field. The second is the automatic valve. Although it meets the requirements of automatic water supply and water shut-off, there is no flow meter or wireless communication port on the valve body, which cannot meet the actual needs of intelligent metering irrigation. Therefore, it is necessary to improve the existing technology to meet the actual needs of modern agricultural intelligent irrigation. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes an interconnected metering ball valve type valve port. Based on the existing electromagnetic sensors and ultrasonic sensors, an integrated ball valve type valve port RTU circuit board is designed to realize wireless operation monitoring and control. The water consumption in the rice fields can be checked and counted through the computer and mobile phone interface, the valve port switch can be monitored, and the water use parameters can be adjusted according to the growth needs of rice for automatic intelligent irrigation.

[0004] In order to achieve the purpose of the present invention, the following specific scheme is proposed: an interconnected metering ball valve type valve port, which includes a sensor, a flange, a water inlet, a converter, a communication interface, an RTU circuit board control room, a water outlet, a water level electrode, a ball valve, and a photovoltaic power generation panel. A water inlet is arranged on the left side of the sensor, and the right side of the central pipe of the sensor is connected to the water inlet of the ball valve. A flange is arranged on the left side of the water inlet of the sensor, and a converter and a communication interface are arranged on the upper end of the sensor. The water outlet on the right side of the ball valve is designed to face upward, and a water level electrode is arranged at the upper inner side of the mouth of the water inlet. A variable speed motor for driving the ball valve switch is designed on the upper end of the ball valve, and the RTU circuit board control room is wired to the communication interface, the water level electrode, and the photovoltaic power generation panel through a signal line.

[0005] The sensor is an electromagnetic sensor or an ultrasonic sensor. A converter is designed on the upper side of the sensor. The converter is connected to the RTU circuit board control room signal through a communication interface.

[0006] The RTU circuit board control room is designed with an RTU circuit board and a battery. The battery is electrically connected to the RTU circuit board, and the RTU circuit board is wiredly connected to a communication interface, a water level electrode, and a photovoltaic power generation panel.

[0007] The photovoltaic power generation panel is installed on one side of the ball valve through a bracket, and an RTU circuit board control room is also installed on the bracket and the RTU circuit board control room is located below the photovoltaic power generation panel.

[0008] The mouth of the water outlet is located higher than the highest water level inside the sensor.

[0009] Compared with the existing technology, the advantages are:

[0010] The interconnected metering ball valve type valve port, because the outlet pipe is designed to discharge water upward and horizontally, ensures the full water flow rate of the sensor center pipe, making the metering accurate. Since the water inlet is designed with a water level electrode, it can play a monitoring role. It opens when there is water in the pipe and closes when there is no water to prevent water from flowing back in the rice field. Since the metering design uses electromagnetic sensors or ultrasonic sensors, there are no moving parts and no obstructing parts inside. When the ball valve is opened, there are also no obstructing parts inside, which is a straight-through type, effectively preventing the blockage of debris inside the water channel when water is entering. Since the RTU circuit board control room is designed with an RTU circuit board and a battery, the function of remotely monitoring and counting the water consumption in the rice field and controlling the opening and closing of the valve port is realized through the computer and mobile phone interface. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 Schematic diagram of the present invention. DETAILED DESCRIPTION

[0012] In order to further illustrate the present invention, the following is introduced in conjunction with the accompanying drawings:

[0013] Refer to the attached Figure 1 As shown, the interconnected metering ball valve type valve port includes a sensor 1, a flange 2, a water inlet 3, a converter 4, a communication interface 5, an RTU circuit board control room 6, a water outlet 7, a water level electrode 8, a ball valve 9, a variable speed motor 10 and a photovoltaic power generation panel 11. The water inlet 3 is arranged on the left side of the central pipe of the sensor 1, and the water inlet of the ball valve 9 is connected to the right side of the central pipe of the sensor 1. The flange 2 is arranged on the left side of the water inlet 3 of the sensor 1. The converter 4 and the communication interface 5 are arranged on the upper end of the sensor 1. The water outlet 7 on the right side of the ball valve 9 is designed to face upward, and the water level electrode 8 is arranged at the upper position of the inner side of the mouth of the water inlet 3. The variable speed motor 10 for driving the ball valve switch is designed on the upper end of the ball valve 9. The RTU circuit board control room 6 is connected to the communication interface 4, the water level electrode 8 and the photovoltaic power generation panel 11 by wire through the signal line. The photovoltaic power generation panel 11 is installed on one side of the ball valve 9 through a bracket 12, and the RTU circuit board control room 6 is also installed on the bracket 12 and the RTU circuit board control room 6 is located below the photovoltaic power generation panel 11. The sensor 1 is an electromagnetic sensor or an ultrasonic sensor. A converter 4 is designed on the upper side of the sensor 1. The converter 4 is connected to the RTU circuit board control room 6 through a communication interface 5.

[0014] The RTU circuit board control room 6 is designed with an RTU circuit board and a battery. The battery is electrically connected to the RTU circuit board, and the RTU circuit board is wiredly connected to the communication interface 5, the water level electrode 8, and the photovoltaic power generation panel 11. The battery supplies power to the RTU circuit board, the variable speed motor, the converter, and the water level electrode. When the photovoltaic power generation panel is working and generating electricity, it also supplies power to the RTU circuit board, the variable speed motor, the converter, and the water level electrode, and charges the battery at the same time. When the photovoltaic power generation panel is not working, the battery supplies power.

[0015] The mouth of the water outlet 7 is located higher than the highest water level inside the sensor 1. In this way, the water that finally flows out of the sensor fills the central pipe of the sensor, ensuring that the flow rate detected inside the sensor is accurate.

[0016] The interconnected metering ball valve type valve port, because the outlet pipe is designed to discharge water upward and horizontally, ensures the full water flow rate of the sensor center pipe, making the measurement accurate. Since the water inlet is designed with a water level electrode, it can play a monitoring role. It opens when there is water in the pipe and closes when there is no water, preventing water from flowing back in the rice field. Since the metering design uses electromagnetic sensors or ultrasonic sensors, there are no moving parts and no flow-blocking parts inside. When the ball valve is opened, there are also no obstruction parts inside, which is a straight-through type, effectively preventing the blockage of debris inside the canal when water is entering. Since the RTU circuit board control room is designed with an RTU circuit board and a battery, the RTU circuit board can be connected to the computer 13 or the mobile phone interface for signal connection, thereby realizing the function of remotely monitoring and counting the water consumption in the rice field and controlling the switch of the valve port through the computer 13 and the mobile phone interface. During operation, when the water level electrode at the water inlet on one side of the sensor detects water, a signal is given through the mobile phone interface or computer 13 for the RTU circuit board to automatically work, so that the variable speed motor can be activated and the ball valve can be opened. At this time, water will enter from one side of the sensor, flow through the ball valve, and enter the farmland from the water outlet until the staff manually controls the RTU circuit board to give a signal to activate the variable speed motor to close the ball valve and stop the water supply, or until the water level electrode detects that there is no water, sends a signal to the RTU circuit board, and the RTU circuit board controls the variable speed motor to control the ball valve to close; if the water level electrode does not detect water at the beginning, the water level electrode transmits a signal to the RTU circuit board, and the RTU circuit board sends a signal to control the variable speed motor to keep the ball valve closed. Once the water level electrode detects that there is water at the water inlet, it will give a signal to control the variable speed motor to operate, and the variable speed motor controls the ball valve to open to irrigate the farmland. To achieve automatic irrigation, the water parameters can be adjusted according to the growth needs of rice through a mobile phone or computer for automatic intelligent irrigation. The sensor transmits the water flow rate to the RTU circuit board through the converter and the communication interface. The RTU circuit board finally transmits the signal to the mobile phone interface or computer to achieve manual real-time monitoring and make adjustments at any time.
