[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Examples, such as Figure 1 - Figure 13 As shown, the present invention provides a technical solution: a high-precision manual / automatic integrated control valve drive device, comprising: a bracket 1, a drive motor 2, a piston 3, a rotating gear 4, a fixed plate 5, a counting infrared sensor 6, an L-shaped support plate 7, a sliding plate 8, an infrared sensor 9, a lever 10, a bearing 11, a screw 12, and a fixing sleeve 13. The inner surface of the bearing 11 is fixedly mounted on the outer surface of the bracket 1 near the top, and the outer surface of the bearing 11 is fixedly mounted on the inner surface of the rotating gear 4. The fixed plate 5 and the rotating gear 4 are fixedly mounted by bolts. The drive motor 2 is fixedly mounted to the bracket 1, and the drive gear of the drive motor 2 meshes with the rotating gear 4. A shaped hole 50 is provided at the center of the fixed plate 5. 2. The screw 12 is located inside the irregular hole 502. One end of the screw 12 is provided with a retaining ring groove 1201. The inner wall of the retaining ring groove 1201 is engaged with a retaining ring 1203. The piston 3 is provided with a threaded groove 302. One end of the screw 12 is threadedly connected to the inside of the threaded groove 302. The outer surface of the piston 3 is provided with a retaining ring groove 301. The inner wall of the retaining ring groove 301 is engaged with a retaining ring 303. The fixed sleeve 13 is fixedly installed with the piston 3 by retaining ring 303. The fixed sleeve 13 is fixedly installed with the lever 10 by bolts. The center of the bracket 1 is provided with an irregular hole 101. The outer surface of the fixed sleeve 13 is slidably connected to the inside of the irregular hole 101.

[0035] Furthermore, such as Figure 1 - Figure 13As shown, the bracket 1 is fixedly connected to the L-shaped support plate 7. A straight groove 701 is provided on one side of the L-shaped support plate 7. A round rod 802 is fixedly connected to the side of the sliding plate 8 near the bottom. The outer surface of the round rod 802 is slidably connected to the inside of the straight groove 701. With the above arrangement, when the sliding plate 8 moves, the round rod 802 can slide to one side along the inside of the straight groove 701.

[0036] Furthermore, such as Figure 1 - Figure 13 As shown, an indicator needle 803 is fixedly connected to the side of the sliding plate 8 near the top, and a scale line 702 is provided on the top of the L-shaped support plate 7. When the piston 3 is stationary, the position indicator needle 803 of the sliding plate 8 points to the control valve position scale line 702 of the L-shaped support plate 7. When the manual controller is not equipped with the control circuit board, infrared sensor 9, counting infrared sensor 6 and drive motor 2, after manually rotating the rotating gear 4 for several revolutions, the position indicator needle 803 of the sliding plate 8 points to the scale line 702 where the piston 3 is stationary, so that the manual can find the required position. Through the above settings, when the sliding plate 8 moves, the indicator needle 803 can be made to point to the scale line 702 at different positions, which facilitates observation during manual adjustment and ensures the accuracy of adjustment.

[0037] Furthermore, such as Figure 1 - Figure 13 As shown, a round rod 1001 is fixedly connected to one side of the lever 10, and a slanted groove 801 is provided on one side of the sliding plate 8. The outer surface of the round rod 1001 is slidably connected to the inside of the slanted groove 801. With the above arrangement, when the lever 10 drives the round rod 1001 to move up or down, the round rod 1001 can slide up or down inside the slanted groove 801, applying a force to the sliding plate 8, causing the sliding plate 8 to slide to one side or the other side.

[0038] Furthermore, such as Figure 1 - Figure 13 As shown, the infrared sensor 9 is fixedly connected to the bracket 1, and a light-blocking plate 1002 is fixedly connected to the side of the lever 10 facing the infrared sensor 9. With the above settings, when the light-blocking plate 1002 blocks the infrared sensor 9, the infrared sensor 9 sends a stop signal to the controller, and the controller cuts off the power supply to the drive motor 2.

[0039] Furthermore, such as Figure 1 - Figure 13 As shown, a limiting step 1202 is provided on the outer surface of the screw 12. The size of the limiting step 1202 is larger than the size of the irregular hole 502. By setting the limiting step 1202, the length of the screw 12 passing through the irregular hole 502 can be controlled.

[0040] Furthermore, such as Figure 1 - Figure 13As shown, the top of the rotating gear 4 is fixedly connected with multiple hollow columns 402 in a circumferential array. The outer surface of the hollow columns 402 is movably connected in the mounting hole 501. The hollow columns 402 are threadedly connected to bolts. Through the above arrangement, the fixed disk 5 and the rotating gear 4 can be fixed together.

[0041] Furthermore, such as Figure 1 - Figure 13 As shown, the inner wall of the irregular hole 101 is arranged in a circumferential array with multiple semi-cylinders, and the outer surface of the fixing sleeve 13 is arranged in a circumferential array with multiple semi-circular grooves. The semi-cylinders and semi-circular grooves cooperate with each other. The fixing sleeve 13 is provided with an irregular hole 1301 inside. One end of the piston 3 is slidably connected to the inside of the irregular hole 1301. Through the above arrangement, the fixing sleeve 13 is limited, so that the fixing sleeve 13 can only slide up and down.

[0042] Furthermore, such as Figure 1 - Figure 13 As shown, the top of the rotating gear 4 has multiple rectangular through holes 401 arranged in a circular array. The counting infrared sensor 6 is fixedly installed on the bracket 1 by a support rod. With the above settings, the counting infrared sensor 6 can record a value by the controller every time it passes through a rectangular through hole 401 of the rotating gear 4. Each value corresponds to the degree of rotation of the rotating gear 4. The more rectangular through holes 401 the rotating gear 4 has, the finer the thread division of the screw 12 will be, and the more accurate the movement distance of the control valve piston 3 will be.

[0043] Furthermore, such as Figure 1 - Figure 13 Figure 1 Figure 13 As shown, the outer surface of the rotating gear 4 has multiple arc-shaped grooves arranged in a circumferential array. The arc-shaped grooves facilitate manual rotation of the rotating gear 4.

[0044] Working principle: When the automatic control head is in use, the controller starts the drive motor 2, causing the drive gear to rotate. Then, under the meshing action of the drive gear and the rotating gear 4, and with the rotation of the rotating gear 4 and the bracket 1 via the bearing 11, the rotating gear 4 can be driven to rotate. With the fixed plate 5 and the rotating gear 4 fixed by bolts, and the screw 12 and the rotating gear 4 fixed by the snap ring 1203, the fixed plate 5 and the screw 12 can be driven to rotate synchronously. Then, with the screw 12 and the piston 3 threaded together, and with the piston 3 and the fixed sleeve 13 fixed by the snap ring 303, and the fixed sleeve 13 sliding inside the irregular hole 101, the piston 3 can be limited, allowing it to move only along the axial direction of the screw 12. Simultaneously, the movement of the fixed sleeve 13 drives the lever 10 upwards, causing the light-blocking plate 1002 to move away from the position of the infrared sensor 9. The detector 9 detects the movement of the light-blocking plate 1002, i.e., the piston 3 moves upward from its initial position. At the same time, with the cooperation of the counting infrared sensor 6 and the rectangular through hole 401, the rotation angle of the rotating gear 4 can be detected. Based on the set angle, it can determine when to power on the drive motor 2 to rotate and when to power off to stop, thus determining the stopping position of the piston 3. Compared with the automatic control head, the manual control head does not install the drive motor 2, the counting infrared sensor 6, and the infrared sensor 9. With the cooperation of the arc groove, it is convenient to rotate the rotating gear 4 by hand. Similarly, the rotation of the screw 12 can drive the piston 3, the fixed sleeve 13, and the lever 10 to move upward, so that the second round rod 1001 slides along the inside of the inclined groove 801, so that the sliding plate 8 slides to one side. Simultaneously, the first round rod 802 slides inside the straight groove 701, so that the indicator needle 803 points to the scale line 702 at different positions, realizing the manual finding of the required position of the piston 3.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
