[0039] This utility model embodiment provides an intelligent rotary control device for power control cabinets.

[0040] The aforementioned power control cabinet includes a cabinet body and knobs exposed within the cabinet body for adjusting the power control cabinet. The cabinet body is roughly flat and rectangular, with its back side fixed to a wall and its front side serving as a panel on which the knobs are mounted. The cabinet body also includes electrical components that can be operated using the knobs; by rotating the knobs, the power control cabinet can be adjusted.

[0041] The intelligent knob control device provided in this embodiment mainly includes a housing 10, a stepper motor 20, a clamp 30, a control circuit board 40, and a transmission assembly 50.

[0042] Reference Figure 1 and Figure 2The housing 10 is a cabinet for fixing to a power control cabinet. It includes a base 11 and a main body 12. The base 11 is adapted to be fixed to the cabinet, and the main body 12 is detachably fixed to the side of the base 11 facing away from the cabinet. A stepper motor 20, a control circuit board 40, and a transmission assembly 50 are mounted on the main body 12. The base 11 has a first through hole 111 extending along a first axis, and the wall of the first through hole 111 has an internal thread 112. The main body 12 has a threaded post 123 for extending into the first through hole 111 and extending along the first axis. A second through hole 124 extending along the first axis is provided in the threaded post 123, and the outer wall of the threaded post 123 has an external thread 125 that threadedly engages with the internal thread 112 of the first through hole 111. The dimensions of the first through hole 111 and / or the second through hole 124 are adapted to accommodate the knob so that the side of the base 11 facing the cabinet is against the cabinet.

[0043] The stepper motor 20 is installed inside the housing 10 and has a drive shaft 21 that can output its torque.

[0044] The clamp 30 protrudes from the side of the housing 10 that is adapted to face the cabinet, and is provided with a clamping groove 31 that is adapted to the knob. It is driven by the stepper motor 20 to rotate relative to the housing 10 about a first axis. When the clamping groove 31 clamps and engages with the knob, the first axis coincides with the rotation axis of the knob. Furthermore, the clamp 30 is located within the first through hole 111 and / or the second through hole 124.

[0045] A control circuit board 40 is mounted on the housing 10 and electrically connected to the stepper motor 20 to control the operation of the stepper motor 20. The control circuit board 40 includes a communication module and a processing module. The communication module is adapted to communicate wirelessly with a server, and the processing module is adapted to control the operation of the stepper motor 20 according to received control commands. The processing module in the control circuit board 40 includes an ESP-12E main control chip or an ESP-01S main control chip and a stepper motor 20 driver board.

[0046] A transmission assembly 50 is mounted on the housing 10 and connected to the drive end of the stepper motor 20 and the clamp 30, respectively, so that the stepper motor 20 can drive the clamp to decelerate or accelerate its rotation around the first axis. The transmission assembly 50 includes at least two meshing gears, the gear shaft 521 of the last gear coincides with the first axis, extends out of the housing 10 to the side facing the cabinet, and is inserted into the clamp 30 in a non-rotating manner along the first axis direction.

[0047] Specifically, first refer to Figure 1The document describes the orientation of the intelligent knob control device provided in this embodiment. The main body 12 is located at the front of the device, and the base 11 is located at the rear of the device. The rear surface of the base 11 can be attached to the front panel of the cabinet. The base 11 can be fixed to the cabinet by adhesive, magnetic attraction, welding, or bolt fastening, and the installation method of the control device can be selected according to actual needs. Furthermore, the aforementioned first axis direction is the front-to-back direction in this embodiment. When the device is installed on the cabinet, the extension direction of the rotation axis of the knob on the cabinet can also be considered as the front-to-back direction.

[0048] Furthermore, the method of fixing the base 11 to the cabinet can be flexibly selected according to the actual application scenario and the cabinet material. For example: ① Strong double-sided adhesive: For cabinets with flat surfaces, industrial-grade strong double-sided adhesive tape can be used to stick and fix the base 11 to the cabinet surface around the knob. This method is simple and quick to install and will not damage the original structure of the cabinet. ② Magnetic adsorption: If the cabinet is made of ferromagnetic material, the contact surface of the base 11 can be integrated with permanent magnets or electromagnets, and fixed to the cabinet surface by magnetic adsorption. This is also easy to install and disassemble, and does not change the cabinet structure. ③ Screw fixing: In some cases where minor modifications to the cabinet are allowed, or when there are already usable screw holes on the cabinet, the base 11 can also be fixed by screws. The design should ensure that the fixing position does not affect the internal wiring and components of the cabinet, and does not damage the protection level of the cabinet. This utility model preferably adopts the first two non-invasive or minimally invasive fixing methods to maintain the integrity and original structure of the power control cabinet to the greatest extent.

[0049] A mounting cavity 121 is formed within the main body 12. The stepper motor 20, circuit control board, and transmission assembly 50 are mounted within this mounting cavity 121. An opening is formed on the front side of the mounting cavity 121, which can be closed during assembly using a suitable cover plate to protect the internal components of the mounting cavity 121. (Refer to...) Figure 5 A mounting post 122 is provided on the bottom wall of the mounting cavity 121, and a corresponding mounting hole 22 is provided on the housing of the stepper motor 20. The mounting post 122 can extend into the mounting hole 22 to position and fix the stepper motor 20. At the same time, a slot is also provided in the mounting cavity 121 to allow the circuit control board to be inserted and fixed.

[0050] A threaded post 123 is provided on the rear side of the main body 12. This threaded post 123 has external threads 125 and a hollow interior forming a second through hole 124, within which the clamp 30 can protrude. Simultaneously, the base 11 has a first through hole 111, the inner wall of which has internal threads 112. (Refer to...) Figure 3 and Figure 4The size of the threaded post 123 on the main body 12 is adapted to the first through hole 111. The two can form a threaded engagement through the internal thread 112 and the external thread 125, thereby fixing the main body 12 to the base 11. The housing 10 includes the base 11 and the main body 12, which are detachably fixed together. When installing the control device, the base 11 is fixed. When it is necessary to replace or repair the components in the main body 12, the main body 12 can be removed without removing the base 11. After the repair is completed, the main body 12 can be directly installed onto the base 11 without reinstalling the entire device, which is more efficient. The base 11 and the main body 12 are fixed by a threaded engagement, which facilitates disassembly and assembly.

[0051] Reference Figure 1 The transmission assembly 50 includes a first gear 51 and a second gear 52, which form a reduction gear mechanism by changing their gear ratio. (See reference...) Figure 2 The drive shaft 21 of the stepper motor 20 is located at its rear. The first gear 51 is directly connected to the drive shaft 21 of the stepper motor 20, and the stepper motor 20 directly drives the first gear 51 to rotate. The first gear 51 meshes with the second gear 52, and the gear shaft 521 of the second gear 52 forms a rotational engagement with the main body 12 and is exposed in the second through hole 124 of the main body 12. The rotation of the second gear 52 can be controlled by controlling the rotation of the drive shaft 21 of the stepper motor 20 through the control circuit board 40. A transmission component 50 is provided so that, at the same stepper motor speed, the torque of the stepper motor 20 can be increased through the transmission component 50, enabling the stepper motor 20 to drive the knob to rotate.

[0052] A clamping groove 31 is provided on the rear side of the clamp 30. The shape and size of the clamping groove 31 are adapted to the corresponding knob, so that the clamp 30 can clamp the knob. When the clamp 30 rotates, it can drive the knob to rotate. Meanwhile, refer to... Figure 2 A connector is provided at the front end of the clamp 30, and a slot is provided at the rear end of the gear shaft 521 of the second gear 52. The connector and the slot are sized to fit together and form a non-rotating engagement. This non-rotating engagement means that after the connector is inserted into the slot, the clamp 30 will not rotate relative to the second gear 52; however, rotation of the second gear 52 will cause the clamp 30 to rotate. (Refer to...) Figure 4 and Figure 6Depending on the length of the clamp 30 and the length of the knob protruding from the front panel of the cabinet, the clamp 30 can be positioned entirely within the second through hole 124 or partially extending into the first through hole 111. Simultaneously, the length of the first through hole 111 should be sufficient to allow the knob to fully enter both the first and second through holes 111 and 124, ensuring that the base 11 can completely rest against the front panel of the cabinet. The clamp 30 is anti-rotatingly engaged with the gear shaft 521 of the last gear in the transmission assembly 50, facilitating the installation and removal of the clamp 30. Different models and specifications of knobs can be adapted by replacing the clamp 30. The first or second hole can accommodate the knob, allowing one side of the base 11 to fully rest against the cabinet, facilitating the installation and fixation of the base 11 and protecting the knob and clamp 30.

[0053] Furthermore, the shape of the clamping groove 31 can be adjusted according to the shape of the knob. In this embodiment, the clamping groove 31 is strip-shaped, which can be adapted to the strip-shaped knob. In other embodiments, for example, when the knob is circular, a high-friction coefficient elastic material, such as rubber or silicone, can be provided on the inner wall of the clamping groove 31, based on the design of the clamping groove 31 as circular. This elastic material can adapt to knobs of different sizes to a certain extent and provide a stable clamping force through friction, preventing relative slippage. Those skilled in the art understand that knobs have different shapes. In this utility model, the shape of the clamping groove 31 needs to be able to form an anti-rotation fit with the shape of the knob. This anti-rotation fit can be achieved through shape matching or by increasing the friction between the knob and the clamping groove 31.

[0054] Furthermore, to achieve remote intelligent control, this intelligent knob control device includes a control circuit board 40. The control circuit board 40 includes a communication module and a processing module. The communication module can communicate with a server. This communication includes the control circuit board 40 sending information to the server and receiving information from the server. The control circuit board 40 can generate corresponding instructions based on the information sent by the server and control the stepper motor 20 to run via the stepper motor driver board. It should be noted that the control of the stepper motor 20 here is a conventional technique in the art. During use, the stepper motor 20 inevitably needs to have its operating parameters controlled by the driver board. Sending control instructions from the main control chip to the driver board is also a conventional technique in the art. Establishing communication with the server through the communication module is also a conventional technique in the art. Establishing a server in the cloud or locally for intelligent monitoring and control is also a conventional technique in the art. Therefore, using the control circuit board 40 to control the stepper motor 20 is a conventional technique in the art and will not be elaborated further here.

[0055] Specifically, the core of the control circuit board 40 consists of a processing module (such as a microcontroller like ESP32 or STM32) and a stepper motor drive module. Its workflow is as follows:

[0056] 1. Command Reception and Parsing: The communication module (such as a Wi-Fi module) receives control commands from a remote server or user terminal. These commands can be "rotate knob A to position X", "rotate knob B clockwise by Y degrees", or "execute preset scenario Z (corresponding to a series of knob operations)". For example, the user wants to switch a circuit breaker knob from "off" to "on", or adjust the temperature control knob from "20℃" to "25℃".

[0057] 2. Motor Control Logic: The processing module parses instructions and converts them into specific control signals for the stepper motor 20. Stepper motors are known for their precise angle control capabilities; their rotation angle is proportional to the number of input pulses. By precisely controlling the number and frequency of pulses sent to the stepper motor driver board, the rotation angle, speed, and direction of the stepper motor can be precisely controlled.

[0058] During initial installation or calibration, the initial position of the knob can be set (e.g., 0 degrees or a specific scale). Each step angle of the stepper motor is known (e.g., 1.8 degrees / step). After the reduction ratio (e.g., N:1) of the transmission assembly 50, the minimum rotation angle of the clamp 30 can be calculated. For example, if the stepper motor step angle is 1.8° and the reduction ratio is 10:1, the clamp will rotate 0.18° for each pulse received. By accumulating the number of pulses, the clamp 30 (and thus the knob) can be precisely controlled to rotate to the target angle. For knobs with specific positions or scales, these positions or scales can be preset as target position parameters. For example, for a knob with 0-5 positions, each 30 degrees apart, the control command can directly specify the target position, and the processing module calculates the number of pulses required for rotation.

[0059] This device can be used to adjust various parameters on the power control cabinet, depending on the function of the knob. For example: switch status switching: switching the selector switch from "manual" to "automatic," or connecting / disconnecting a circuit. Setpoint adjustment: adjusting the frequency setting knob of the frequency converter, the temperature setting knob of the temperature controller, the duration setting knob of the timer, etc. Mode selection: selecting the operating mode of the equipment, such as "energy-saving mode," "full power mode," etc.

[0060] Furthermore, the intelligent knob control device provided by this utility model allows users to remotely monitor and operate the knobs of the power control cabinet via a mobile app or cloud platform. Regardless of location, users can control the equipment, such as remotely turning on / off the water pumps of an irrigation system (by operating the corresponding knobs on the control cabinet). Control logic or scenarios can be preset. For example, based on sensor data (such as soil moisture and light intensity, which are collected by other IoT devices and transmitted to this device via a server), the relevant knobs can be automatically adjusted. For instance, when soil moisture is below a threshold, the irrigation pump's on / off knob is automatically turned to the "on" position; when the temperature is too high, the fan speed knob on the ventilation equipment control cabinet is automatically adjusted. Alternatively, timed tasks can be set to automatically execute knob operations at specific times, such as timed switching of lighting or timed starting / stopping of equipment.

[0061] Furthermore, encoders or sensors can be added to detect the actual position of the knob, forming a closed-loop control. Operation records and knob status can be uploaded to the server for easy traceability and analysis.

[0062] This embodiment provides an intelligent knob control device for power control cabinets. This device can simulate human hand operation of a knob, realizing the intelligent transformation of traditional power control cabinets. The device is fixed to the cabinet body via a housing 10, and the clamping slot 31 of the clamp 30 in the device forms a clamping engagement with the knob on the cabinet body. Then, the control circuit board 40 receives corresponding control commands and drives the stepper motor 20 to run. The stepper motor 20 drives the clamp 30 to rotate, thereby simulating human hand operation of the knob. By adding this intelligent knob control device to the power control cabinet, the intelligent transformation of traditional power control cabinets can be achieved simply and quickly, effectively reducing the transformation cost and difficulty.

[0063] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
