Description

Technical Field

[0001] This utility model relates to an actuator, and more particularly to a pulse counting actuator. Background Technology

[0002] Inside metering devices such as water meters and heat meters, there are actuators used to control the opening and closing of ball valves. The actuators include a motor, a transmission mechanism, and a lever. The motor drives the lever to swing through the transmission mechanism, and the lever moves the ball valve to open and close it.

[0003] Existing actuators can only operate in two modes: fully open or fully closed. They cannot flexibly adjust the opening and closing range of the ball valve as needed; in other words, the swing range of the lever cannot be adjusted flexibly. The main reason for this inflexibility is the lack of effective feedback on the lever's swing stroke during operation. Currently, there are methods that install infrared sensors within the valve body to provide feedback on the lever's swing stroke, but these are all separate, additional installations.

[0004] To achieve convenient installation and a compact, integrated structure, the inventors improved the structure of existing actuators by integrating the lever travel feedback structure and circuit board onto the actuator itself. This results in high integration, compactness, and a small footprint. Furthermore, the integrated components can be installed as a single unit, making installation extremely convenient. Currently, this design has been successfully manufactured into a product, demonstrating excellent performance and promising prospects for widespread adoption. Summary of the Invention

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution. Example 1

[0025] like Figure 1-5 As shown, this utility model includes an actuator body 1, a circuit board, and a lever travel feedback structure. The circuit board is mounted on the actuator body. The actuator body 1 includes an upper panel 2 and a lower panel 4, which are connected by screws. A motor 7 is mounted on the upper panel 2, and a gear set is arranged between the upper panel 2 and the lower panel 4. The motor 7 drives the lever 14 to swing through the gear set. The lever travel feedback structure includes a counting gear 11, an infrared photoelectric transmitter 13, and an infrared photoelectric receiver 10. The counting gear 11 is mounted between the upper panel 2 and the lower panel 4 and is driven by the gear set. The infrared photoelectric transmitter 13 and the infrared photoelectric receiver 10 are mounted on the circuit board.

[0026] The circuit board includes an upper circuit board 5 and a lower circuit board 9, which are respectively installed on the upper and lower sides of the actuator body. An infrared photoelectric transmitter 13 is installed on the upper circuit board 5 and is connected to the circuit of the upper circuit board 5. An infrared photoelectric receiver 10 is installed on the lower circuit board 9 and is connected to the circuit of the lower circuit board 9. Both the upper circuit board 5 and the lower circuit board 9 are connected to the controller circuit.

[0027] In this embodiment, the counting gear 11 has multiple through holes 23, and the upper plate 2 and lower plate 4 have light-transmitting holes 12 that mate with the through holes 23. The infrared photoelectric transmitter 13, the infrared photoelectric receiver 10, and the light-transmitting holes 12 are located on the same straight line. When the infrared signal emitted by the infrared photoelectric transmitter 13 is blocked by the counting gear 11, the infrared photoelectric receiver 10 cannot receive the signal; when the through holes 23 on the counting gear 11 rotate to face the light-transmitting holes 12, the infrared photoelectric receiver 10 can receive the infrared signal. The counting gear 11 outputs a rectangular pulse signal when passing between the infrared photoelectric transmitter 13 and the infrared photoelectric receiver 10.

[0028] In this embodiment, a first arc-shaped clearance hole 3 is provided on the top plate 2 for the lever 14 to swing, and a second arc-shaped clearance hole 8 is provided on the upper circuit board 5 at the position opposite to the first arc-shaped clearance hole 3. The lever 14 passes through the first arc-shaped clearance hole 3 and the second arc-shaped clearance hole 8 in sequence.

[0029] In this embodiment, the upper circuit board 5 is fixed to the upper panel 2 with screws, and the lower circuit board 9 is fixed to the lower panel 4 with screws. Furthermore, the upper circuit board 5 is provided with a mounting hole 6 for the motor 7 housing to pass through, so that the upper circuit board 5 can be attached to the upper panel 2.

[0030] In this embodiment, the gear set includes a first transmission gear 15, a second transmission gear 16, a third transmission gear 17, a fourth transmission gear 18, a fifth transmission gear 19, a sixth transmission gear 20, a seventh transmission gear 21, and a sector gear 22. The first transmission gear 15 is mounted on the output shaft of the motor 7. The first transmission gear 15, the second transmission gear 16, the third transmission gear 17, the fourth transmission gear 18, the fifth transmission gear 19, the sixth transmission gear 20, and the seventh transmission gear 21 mesh sequentially. The lever 14 is mounted on the sector gear 22. The motor 7 provides power, and the lever 14 swings through the meshing transmission of the gear set. Furthermore, the counting gear 11 meshes with the fifth transmission gear 19.

[0031] In practical use, the lever 14 is driven by the motor 7 to swing, and the lever 14 is used to move the ball valve to open and close the ball valve. During the swing of the lever 14, the counting gear 11 can be synchronously rotated based on the transmission of the gear set. When the counting gear 11 passes between the infrared photoelectric transmitter 13 and the infrared photoelectric receiver 10, it will output a rectangular pulse signal. The signal is transmitted to the controller, so the swing stroke of the lever 14 can be fed back in real time, and the opening and closing range of the ball valve can be flexibly adjusted as needed.

[0032] This invention improves upon the structure of existing actuators by integrating the lever travel feedback structure and circuit board onto the actuator, achieving high integration, compactness, and small footprint. Furthermore, the integrated structure allows for seamless installation. This design has already been commercialized, demonstrating excellent performance and promising prospects for widespread adoption. Example 2

[0033] The difference between Example 2 and Example 1 is that the circuit board is a single unit, an infrared sensor integrating transceiver is installed on the circuit board, and a light-transmitting hole that matches the through hole is provided on the circuit board.
