[0001] This utility model relates to the field of ball valve technology, and in particular to an electric ball valve device that combines manual and automatic operation. Background Technology

[0002] Agricultural intelligent manual / automatic integrated electric ball valves are important fluid control devices widely used in agricultural irrigation, intelligent drip irrigation, and other fields. Existing electric ball valves typically only have electric control functions. In the event of power outages, motor failures, or other emergencies, the valve cannot be operated, affecting the normal operation of the system and potentially causing safety accidents. While some electric ball valves have a manual operation mechanism, the switching between manual and electric modes is not convenient, the operation is complex, and problems such as jamming can easily occur during the switching process, affecting the reliability of the valve.

The bottom surface of the bottom shell 2 is provided with a connection port 15. A horizontal array of mating interfaces 16 is provided on one side of the connection port 15, and a snap fastener 17 is provided on the other side. A sealing ring 14 is provided between the bottom shell 2 and the top shell 3. The side of the valve body 1 is provided with a first mounting port 4, and both ends of the top surface of the valve body 1 are provided with second mounting ports 5. A ball 18 is provided inside the valve body 1, and a valve stem 19 is provided on the top surface of the ball 18. The bottom shell 2 is installed on the top surface of the valve body 1 and is bolted to the valve body 1. The sealing ring 14 is installed on the top surface of the bottom shell 2, and the top shell... 3 is installed on the top surface of the sealing ring 14. The bottom shell 2 and the top shell 3 are bolted together. The photovoltaic solar panel 7 is installed on the top surface of the top shell 3 and is bonded to the top shell 3. The circuit board 9 inside the bottom shell 2 is bolted to the bottom shell 2. The battery 10 is installed inside the bottom shell 2 and is plugged into the bottom shell 2. The electric drive assembly 11 and the manual drive assembly 12 are both installed inside the bottom shell 2. The position of the manual drive assembly 12 corresponds one-to-one with the position of the insertion hole 6. The valve body 1 is T-shaped, and the first mounting port 4 is located at... At the middle position of the side of the valve body 1, the second mounting port 5 is installed at both ends of the top surface of the valve body 1. The magnetic switch 13 is installed on the inner wall of the bottom surface of the top shell 3 and is bolted to the top shell 3. The connection port 15 is located at the middle position of the bottom surface of the bottom shell 2. The buckle 17 and the mating interface 16 are mirrored with the connection port 15 as the center. The buckle 17 is integrally formed with the bottom shell 2. The ball 18 inside the valve body 1 is integrally formed with the valve stem 19 on the top surface. The top end of the valve stem 19 penetrates the valve body 1 and is installed into the interior of the bottom shell 2 through the connection port 15 of the bottom shell 2.

[0017] The valve body 1 is a T-shaped shell, with an integrally formed ball 18 and a valve stem 19 penetrating the top surface installed inside. The ball 18 rotates coaxially with the valve stem 19 to open and close the flow path. The top of the valve stem 19 protrudes from the top of the valve body 1 and enters the bottom shell 2 through the connection port 15 on the bottom surface of the bottom shell 2. The bottom shell 2 and the top shell 3 are fastened together with a sealing ring 14 and bolts to form a waterproof and dustproof chamber. A photovoltaic solar panel 7 is bonded to the surface of the top shell 3 to charge the internal battery 10 and power the electronic components. Baffles are set around the inner side of the bottom shell 2 to limit the lateral displacement of the motor and gears in the electro-pneumatic assembly 11 under torque, ensuring that the transmission axis is concentric. The electric drive assembly 11 is a structure that realizes the automatic opening and closing of the valve. It mainly consists of a motor, a reduction gear set, an output gear, a support bearing, and a mounting bracket. The motor is mounted on a fixed bracket inside the bottom shell 2. The output shaft is rigidly connected to the driving gear in the gear transmission assembly. Under the control of the motor drive circuit of the circuit board 9, the motor receives start, stop, and direction commands from the microcontroller to realize forward and reverse control. The drive gear meshes with the intermediate gear, which in turn drives the output gear, forming a multi-stage reduction transmission. This allows for a larger output torque while maintaining a relatively low motor speed. The output gear meshes with one end of the clutch sleeve of the switching mechanism. When operating in electric mode, the clutch sleeve is pushed towards the electric side by the shift fork and fully meshes with the output gear. The torque generated by the motor is transmitted to the valve stem 19 via the gear set, clutch sleeve, and spline, causing the ball 18 inside the valve body to rotate, thus opening or closing the valve. The electric drive assembly 11 is mounted on a positioning seat inside the bottom housing 2, and a baffle inside the bottom housing 2 prevents the motor from shifting under high torque, ensuring that the transmission center is concentric with the axis of the valve stem 19. The manual drive assembly 12 is used for manual emergency operation in case of power failure or motor malfunction. It mainly consists of a manual lever, a manual drive gear, a manual output gear, a bearing housing, and a limiting structure. The manual lever is connected to the hex wrench 8 via the insertion hole 6. When the operator inserts and rotates the wrench, the torque is transmitted to the manual drive gear via the manual lever. The manual drive gear meshes with the manual output gear, and the center of the manual output gear is opposite to the other end of the clutch sleeve. When the switching mechanism is in manual operation, the shift fork drives the clutch sleeve to move axially along the valve stem 19, disengaging from the electric output gear and meshing with the manual output gear. The manual output gear can then be splined to the valve stem 19 via the clutch sleeve, directly transmitting the torque from manual rotation to the valve stem 19, thereby driving the ball 18 to rotate and open / close the valve. The bearing seat of the manual drive assembly 12 supports the manual gear and reduces frictional resistance during operation. The limiting structure prevents the clutch sleeve from overtravel during operation. The clutch sleeve is fitted onto the valve stem 19 and splined with the valve stem 19 to ensure concentric rotation. The spring is fitted onto the valve stem 19 and provides preload force between the clutch sleeve and the limiting step of the valve stem 19. The shift fork connects to the clutch sleeve and drives the clutch sleeve to move axially along the valve stem 19 under the action of external force, so that the clutch sleeve can engage or disengage with the electric output gear or the manual output gear.When the clutch sleeve moves towards the electric side, it engages the output gear and compresses the spring, disengaging the manual side gear. The motor then drives and controls the valve stem 19 via the gear chain. When the clutch sleeve moves towards the manual side, it engages with the manual output gear, the spring returns to its original position or is compressed to a new equilibrium position, and the electric drive is mechanically isolated. The operator can insert the hex wrench 8 into the socket 6 of the top housing 3, and the torque is output to the clutch sleeve via the manual drive gear and then transmitted to the valve stem 19. A manual wrench clip 17 is provided on the bottom surface to store spare hex wrenches 8. The interfaces 16 and clips 17 are arranged mirror images of the valve body 1 opening. The second mounting port 5 is used for pressure sensor installation, and the first mounting port 4 is used for flow sensor installation. The four interfaces 16 on the bottom surface of the bottom housing 2 are used for connecting external inlet pressure sensors, outlet pressure sensors, inlet flow sensors, and external power supplies, respectively. The mechanical mounting ports of these sensors are directly connected to the flow channel of the valve body 1 to ensure the representativeness of the measured fluid, and are connected to the circuit board 9 inside the bottom housing 2 via cables.

[0018] Circuit board 9 is fixed inside the base shell 2 and includes a microcontroller, motor drive circuit, communication module, sensor interface, and power management circuit. Battery 10 is plugged into the base shell 2 to provide power to the device. Photovoltaic solar panel 7 charges battery 10 through reverse connection protection and constant current / constant voltage charging management circuit. The power management circuit samples the voltage, current, and temperature of battery 10 and reports the power status to the microcontroller. The microcontroller determines the working mode and limit action based on the power status, external control commands, and sensor feedback. The microcontroller outputs PWM or direction control signals to the motor through the motor drive circuit. After receiving commands from the microcontroller, the motor drive circuit controls the start, stop, speed, and direction of the motor, and realizes stall detection and torque estimation through current detection. When the drive motor rotates and the current suddenly increases or reaches a preset threshold, the current detection feeds back to the microcontroller as overload or limit protection, and the microcontroller will cut off the drive or issue an alarm. The communication module supports Bluetooth, Wi-Fi, and LoRa. The microcontroller communicates with the communication module via serial or SPI bus. External control devices can send valve opening and closing commands and query valve position and sensor data via wireless link. The status information sent by the microcontroller includes valve position, power supply status, fault codes, and sensor readings. A magnetic switch 13 is installed inside the top housing 3 and bolted to it for fixation. The magnetic switch 13 is used to control the start and stop of the device. Its working principle is that when a component with a magnet moves into the sensing range of the magnetic switch 13, the switch closes or opens. The microcontroller reads the switch status to confirm whether safety conditions are met before allowing the motor to operate or allowing switching from electric to manual operation. The magnetic switch 13 can also be used as a simple valve position detection point and for protection against misoperation. The sensor interface provides analog and digital inputs. Pressure and flow sensors are connected to circuit board 9 via differential measurement. The microcontroller samples the data via ADC and converts it into engineering quantities according to the calibration curve. The sensor data is used in real time for control strategies or reported via communication. The control logic includes position control and protection logic. Position control can estimate the opening degree by combining timing and current, or use closed-loop control when an additional encoder is implemented in the system. The protection logic includes undervoltage lockout, overcurrent protection, overtemperature protection, and communication timeout protection. When the microcontroller detects any of the protection conditions, it enters a safe state and stops the motor. If necessary, it cuts off the drive output and issues an alarm through the communication module. The interface design considers field maintenance and compatibility. The valve body 1 opening is compatible with common interfaces on the market. When mains power is available, the external power supply to interface 16 can directly supply power and prioritize charging the battery 10 or switch the power supply path. Specific Implementation Example 2: Reference Figure 1-6A manual / automatic electric ball valve device, further based on the basic structure in Specific Embodiment 1, features a direct rigid connection between the motor and the drive gear. The gear chain ensures torque transmission ratio and speed matching. The meshing surface of the output gear and the clutch sleeve uses a keyway or spline to ensure torque transmission and concentricity. The axial movement of the clutch sleeve is driven by an actuator or mechanical linkage via a shift fork and is preloaded by a spring. The spring preload ensures that the clutch sleeve remains on the default working side to avoid drift when there is no external force. The position of the shift fork is mechanically limited or detected by a microcontroller via a magnetic switch 13, and the motor output is only allowed after the switching is completed. The connection end between the manual drive gear and the manual wrench has a self-locking structure to prevent accidental dislodgement. The bottom shell 2 baffle bears the lateral force at the moment of motor start-up and transmits it to the shell bolts and stiffening ribs. The sealing ring 14 between the top shell 3 and the bottom shell 2 withstands changes in ambient temperature and vibration.

[0020] In summary: 1. When the electric ball valve is in electric drive mode, circuit board 9 sends a control signal to electric drive assembly 11. The motor in electric drive assembly 11 starts and reverses direction according to the control command. The torque of the motor is transmitted to valve stem 19 through gears inside the bottom shell 2, causing valve stem 19 to rotate ball 18 inside valve body 1, thereby opening or closing the valve. During this process, the switching mechanism automatically keeps the gear engaged with valve stem 19, while disengaging the manual transmission assembly from valve stem 19. This ensures that the manual mechanism is not stressed or involved in transmission during electric drive, avoiding wear or interference from the motor on the manual mechanism. When manual operation is required, or in case of power failure or motor failure, the operator can insert a manual hex wrench 8 and turn the handle to drive the manual transmission assembly. The manual transmission assembly directly transmits torque to valve stem 19, thereby rotating ball 18 to open or close the valve. This solves the problem of complex operation of electric ball valves.
