[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 The manual-automatic ball valve actuator includes a housing 1. A mounting cylinder 2 is integrally formed at the bottom of the housing 1. A rotating cylinder 3 is rotatably inserted in the mounting cylinder 2. A rotating column 4 is slidably inserted at the top of the rotating cylinder 3. The top of the rotating column 4 passes through the top of the housing 1 and is clamped with a connecting button 5. An upper groove 6 is provided on the top of the housing 1. When the connecting button 5 is pressed, it is located in the upper groove 6. When the connecting button 5 is turned, the rotating column 4 is rotated, thereby driving the rotating cylinder 3 to rotate, and then driving the valve stem to rotate, so that the valve is manually opened and closed. A connecting shell 7 is fixed in the housing 1 by bolts, and a driving assembly 8 is provided in the connecting shell 7.

[0024] The driving assembly 8 includes a motor 807, which is fixed to the bottom inner wall of the connecting shell 7 by bolts. The output end of the motor 807 is keyed to a worm 808. A front shaft 801 is rotatably connected between the top inner wall and the bottom inner wall of the connecting shell 7. The outer wall key of the front shaft 801 is connected to a worm wheel 802 and a front gear 803. The worm wheel 802 is meshed with the worm 808. A rear shaft 804 is rotatably connected between the top inner wall and the bottom inner wall of the connecting shell 7. The outer wall key of the rear shaft 804 is connected to a rear gear 805. The rear gear 805 is connected to the front gear 803. The gear 803 is engaged, and the outer wall of the circumference of the rotating column 4 is keyed to a transmission gear 806, which can be engaged with the rear gear 805. Driven by the motor 807, the worm 808 rotates, and the front gear 803 is driven to rotate by the meshing of the worm 808 and the worm wheel 802. Then, the rotating column 4 is driven to rotate by the meshing of the front gear 803 and the rear gear 805 and the meshing of the rear gear 805 and the transmission gear 806, thereby driving the valve stem of the valve to rotate, thereby automatically opening and closing the valve.

[0025] The circumferential outer wall of the rotating column 4 is fixed with a limit seat 9, and the circumferential outer wall of the rotating column 4 is sleeved with a spring 10. Under the action of the spring 10, the rotating column 4 is reset, so that the transmission gear 806 is engaged with the rear gear 805, thereby facilitating automatic operation of the valve. A touch screen 11 is embedded in the top of the shell 1, and a support plate 12 is fixed between the inner walls of multiple sides of the shell 1 by bolts. A controller 13 is fixed to the top of the support plate 12 by bolts. The controller 13 is electrically connected to the motor 807 and the touch screen 11. The model of the controller 13 is DATA-7311.

[0026] The top outer wall of the connecting shell 7 is fixed with a battery 14 by bolts. The battery 14 is electrically connected to the motor 807, the touch screen 11 and the controller 13, thereby providing power to the motor 807, the touch screen 11 and the controller 13. The top outer wall of the connecting shell 7 is provided with a fixed line component 15. The fixed line component 15 includes a connecting seat 1501. The connecting seat 1501 is fixed to the top outer wall of the connecting shell 7 by bolts. The top of the connecting seat 1501 is rotatably connected to the arc seat 1502. A fastening screw 1503 is threadedly inserted between the arc seat 1502 and the connecting seat 1501 to connect the connecting seat. The wiring is placed on the connecting seat 1501, and then the arc seat 1502 is pulled to press on the connecting wire, and the arc seat 1502 is fixed with the fastening screw 1503 to fix the connecting wire. The bottom of the arc seat 1502 and the top of the connecting seat 1501 are both bonded with anti-slip pads 16 to prevent the connecting wire from sliding. The bottom of the shell 1 is integrally formed with a rubber tube 17, and the bottom end of the rubber tube 17 is clamped with a rubber sheet 18 to prevent dust from entering the shell 1. The bottom of the rubber sheet 18 is provided with a cross notch 19 to facilitate the connection line to be passed through the cross notch 19 into the shell 1.

[0027] The working principle of this embodiment is as follows: During installation, the connecting wire is passed through the cross notch 19 into the housing 1, and then the connecting wire is placed on the connecting seat 1501. The curved seat 1502 is then moved to press onto the connecting wire, and the curved seat 1502 is fixed with the fastening screw 1503, thereby fixing the connecting wire. Then, the rotating cylinder 3 is connected to the valve stem of the valve;

[0028] When manual operation is required, the connecting button 5 is pressed downward to press it into the upper groove 6, thereby driving the rotating column 4 to move downward, and then driving the transmission gear 806 to move downward and separate from the rear gear 805. Then, the connecting button 5 is pressed and turned to drive the rotating column 4 to rotate, thereby driving the rotating cylinder 3 to rotate, and then driving the valve stem to rotate, so that the valve is manually opened and closed;

[0029] When automatic operation is required, the connecting button 5 is released, and the rotating column 4 is reset under the action of the spring 10, so that the transmission gear 806 is engaged with the rear gear 805. Then, the transmission signal is clicked on the touch display screen 11 to start the motor 807 through the controller 13. The worm 808 is driven by the motor 807 to rotate, and then the front gear 803 is driven to rotate under the action of the engagement of the worm 808 and the worm wheel 802. Then, the rotating column 4 is driven to rotate under the action of the engagement of the front gear 803 and the rear gear 805 and the engagement of the rear gear 805 and the transmission gear 806, thereby driving the valve stem of the valve to rotate, and then automatically realizing the opening and closing of the valve.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
