[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0017] Please see Figure 1-4 This utility model provides a detachable modular valve drive device, including a drive housing 1. A mounting slot 2 is provided on one side of the top of the drive housing 1. A mounting plate 3 is engaged inside the mounting slot 2. A motor 13 is fixedly installed in the middle of the bottom of the mounting plate 3. A drive gear 14 is fixedly connected to the output end of the motor 13. A rotating shaft 9 is rotatably mounted on the top of the inner side of the drive housing 1. A driven gear 10 is fixedly mounted in the middle of the surface of the rotating shaft 9. Fixing bolts 5 are threaded onto the four corners of the top of the mounting plate 3. First threaded holes 6 are provided at the four corners of the bottom of the inner wall of the mounting slot 2. The four fixing bolts 5 are threaded into the four first threaded holes 6 respectively. Second threaded holes 15 are provided at the connection points between the mounting plate 3 and the four fixing bolts 5. The four second threaded holes 15 are threaded into the four fixing bolts 5 respectively. Positioning slots 7 are provided on both sides of the connection between the mounting plate 3 and the mounting slot 2. Positioning blocks 16 are fixedly installed on both sides of the connection between the mounting plate 3 and the mounting slot 2. The two positioning blocks 16 are respectively engaged with the two positioning slots 7. The limiting engagement between the mounting slot 2 and the mounting plate 3 facilitates the initial positioning of the drive module. The limiting engagement between the two positioning blocks 16 and the two positioning slots 7 facilitates the further positioning of the drive module. The four fixing bolts 5 are respectively fixed to the threads of the four first threaded holes 6 to facilitate the stable installation of the drive module. By loosening the four fixing bolts 5, the drive module is separated from the four first threaded holes 6 and the mounting plate 3 is no longer fixed. Then, by using a larger force to pull the auxiliary handle 4 upward, the two positioning blocks 16 are separated from the two positioning slots 7, which facilitates the quick disassembly and maintenance of the drive module.

[0018] In this embodiment, to ensure the stable installation of the mounting plate 3 within the mounting slot 2, multiple fixing methods are employed. Each of the four corners at the top of the mounting plate 3 is threaded with a fixing bolt 5. Each of the four corners at the bottom of the inner wall of the mounting slot 2 is provided with a first threaded hole 6. The four fixing bolts 5 are threaded into the four first threaded holes 6, initially fixing the mounting plate 3 to the drive housing 1. Simultaneously, each connection point between the mounting plate 3 and the four fixing bolts 5 is provided with a second threaded hole 15, which is threaded into the four fixing bolts 5, further enhancing the stability of the fixation. Positioning slots 7 are also provided on both sides of the connection point between the mounting slot 2 and the mounting plate 3. Positioning blocks 16 are fixedly installed on both sides of the connection point between the mounting plate 3 and the mounting slot 2, and the two positioning blocks 16 are engaged with the two positioning slots 7 respectively. The design of the positioning slot 7 and positioning block 16 enables quick and accurate positioning of the mounting plate 3 during installation, ensuring precise alignment of the motor 13 and drive gear 14 with other components within the drive housing 1. This improves installation efficiency and accuracy. A rotating shaft 9 is rotatably mounted on the top inner side of the drive housing 1. The rotating shaft 9 is connected to the drive housing 1 via high-precision bearings, ensuring smooth rotation of the rotating shaft 9. A driven gear 10 is fixedly mounted in the middle of the surface of the rotating shaft 9. The driven gear 10 meshes with the drive gear 14. When the motor 13 drives the drive gear 14 to rotate, power is transmitted to the driven gear 10 through gear meshing, thereby driving the rotating shaft 9 to rotate. The other end of the rotating shaft 9 is typically connected to the valve stem of a valve, and the rotation of the rotating shaft 9 enables the valve to open, close, or be adjusted. Example 2

[0019] Please see Figure 1-4This utility model provides a detachable modular valve drive device, including a drive housing 1. A mounting slot 2 is provided on one side of the top of the drive housing 1. A mounting plate 3 is engaged inside the mounting slot 2. A motor 13 is fixedly installed in the middle of the bottom of the mounting plate 3. A drive gear 14 is fixedly connected to the output end of the motor 13. A rotating shaft 9 is rotatably mounted on the top of the inner side of the drive housing 1. A driven gear 10 is fixedly mounted in the middle of the surface of the rotating shaft 9. Fixing bolts 5 are threaded onto the four corners of the top of the mounting plate 3. First threaded holes 6 are provided at the four corners of the bottom of the inner wall of the mounting slot 2. The four fixing bolts 5 are threaded into the four first threaded holes 6 respectively. An auxiliary through groove 8 is provided in the middle of the bottom of the inner wall of the mounting slot 2. The auxiliary through slot 8 is set corresponding to the motor 13. An auxiliary handle 4 is fixedly set at the middle of the top of the mounting plate 3. The mounting slot 2 and the mounting plate 3 are engaged to facilitate the initial positioning of the drive module. The two positioning blocks 16 are engaged with the two positioning slots 7 respectively to facilitate the further positioning of the drive module. The four fixing bolts 5 are fixed with the threads of the four first threaded holes 6 respectively to facilitate the stable installation of the drive module. By loosening the four fixing bolts 5, the drive module is separated from the four first threaded holes 6 and the mounting plate 3 is no longer fixed. Then, the auxiliary handle 4 is pulled upward with a larger force to separate the two positioning blocks 16 from the two positioning slots 7, thereby facilitating the quick disassembly and maintenance of the drive module.

[0020] In this embodiment, a mounting slot 2 is carefully designed on one side of the top of the drive housing 1. This slot is a key installation location in the entire modular design. The size and shape of the mounting slot 2 are precisely calculated and designed to perfectly match the mounting plate 3. The mounting plate 3, as the mounting carrier for the motor 13, is made of a high-strength material similar to the drive housing 1 to ensure stable support for the motor 13 and its related components. When the motor module needs to be installed onto the drive device, the mounting plate 3 is simply placed accurately into the mounting slot 2. The inner wall of the mounting slot 2 is smoothed to reduce friction with the mounting plate 3, making the installation process smoother. Simultaneously, the edges of the inner wall of the mounting slot 2 are chamfered to prevent scratches and damage to the mounting plate 3 during installation and disassembly. The auxiliary handle 4 adopts an ergonomic shape and size, and its surface is treated with an anti-slip coating to increase friction for the operator's grip, ensuring a firm grip when installing and removing the mounting plate 3. During installation, the operator can easily lift the mounting plate 3 and accurately place it into the mounting slot 2 using the auxiliary handle 4; during disassembly, simply hold the auxiliary handle 4 and lift it upwards to remove the mounting plate 3 along with the motor module. The operation is convenient and quick, greatly reducing the labor intensity of the operator. Example 3

[0021] Please see Figure 1-4This utility model provides a detachable modular valve drive device, including a drive housing 1. A mounting slot 2 is provided on one side of the top of the drive housing 1. A mounting plate 3 is engaged inside the mounting slot 2. A motor 13 is fixedly installed at the center of the bottom of the mounting plate 3. A drive gear 14 is fixedly connected to the output end of the motor 13. A rotating shaft 9 is rotatably mounted on the top of the inner side of the drive housing 1. A driven gear 10 is fixedly mounted on the center of the surface of the rotating shaft 9. Fixing bolts 5 are threaded onto the four corners of the top of the mounting plate 3. First threaded holes 6 are provided at the four corners of the bottom of the inner wall of the mounting slot 2. The four fixing bolts 5 are threaded into the four first threaded holes 6 respectively. A control panel 17 is fixedly mounted on the front of the drive housing 1. The drive gear 14 and the driven gear... The wheel 10 is engaged with the rotating shaft 9, and a connecting bracket 11 is fixedly installed at the bottom of the rotating shaft 9. A drive head 12 is engaged at the bottom of the connecting bracket 11. The drive module is initially limited by the positioning slot 2 and the positioning plate 3. The drive module is further limited by the two positioning blocks 16 and the two positioning slots 7 respectively. The drive module is securely installed by the four fixing bolts 5 and the four first threaded holes 6 respectively. By loosening the four fixing bolts 5, the drive module is separated from the four first threaded holes 6 and the positioning plate 3 is no longer fixed. Then, the auxiliary handle 4 is pulled upward with a large force to separate the two positioning blocks 16 from the two positioning slots 7, which facilitates the quick disassembly and maintenance of the drive module.

[0022] In this embodiment, the output end of the motor 13 is fixedly connected to the drive gear 14, which is manufactured using high-precision machining to ensure accurate tooth profile and smooth surface. A rotating shaft 9 is rotatably mounted on the top of the inner side of the drive housing 1 via a high-precision bearing, allowing for smooth and low-noise rotation. A driven gear 10 is fixedly mounted in the middle of the surface of the rotating shaft 9, meshing with the drive gear 14 to form a gear transmission mechanism. When the motor 13 starts, the drive gear 14 drives the driven gear 10 to rotate, thereby transmitting the motor's rotational power to the rotating shaft 9. This gear transmission method has advantages such as stable transmission ratio, high transmission efficiency, and compact structure, accurately converting the motor's power into the rotation of the rotating shaft 9. The drive head 12 is engaged at the bottom end of the connecting seat 11 and is directly connected to the valve stem. The shape and size of the drive head 12 are designed according to different types of valves, ensuring perfect matching with various standard or non-standard valve stems. For example, for a ball valve, the actuator 12 may be designed to match the square or keyway structure of the ball valve stem; for a butterfly valve, the actuator 12 may be designed to correspond to the round or flat structure of the butterfly valve stem. Through the connection between the actuator 12 and the valve stem, the rotation of the rotating shaft 9 can be accurately transmitted to the valve, realizing the opening, closing, or regulating actions of the valve.
