Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a speed controller for aquaculture fans. Background Technology

[0002] As a fundamental environmental control device, fans play a crucial role in modern large-scale livestock and poultry farming. Their applications cover various farming scenarios, including poultry houses, pig farms, and cattle sheds. Through forced ventilation, fans significantly improve air circulation in enclosed or semi-enclosed livestock sheds, effectively dispersing harmful gases such as ammonia, hydrogen sulfide, and carbon dioxide, as well as excess moisture, generated by livestock and poultry respiration and excrement decomposition. Simultaneously, they introduce fresh air, thereby significantly reducing the concentration of pathogenic microorganisms in the shed and decreasing the incidence of respiratory diseases.

[0003] Meanwhile, existing speed control methods are inefficient at low speeds, with electrical energy being wasted as heat, resulting in minimal or even higher reductions in actual fan power consumption, thus increasing long-term operating costs for farms. Furthermore, the overly simplistic functionality of existing controllers is a common flaw. Most existing controllers focus solely on fan speed control, lacking integration with other environmental parameters and failing to make optimal ventilation decisions based on multi-factor analysis. This hinders the overall integration and optimization of the aquaculture environment control system, limiting its intelligence level and adaptability to complex and changing environmental conditions.

[0004] Based on this, a speed controller for aquaculture fans is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, the aquaculture fan speed controller includes a controller and a fan. The controller is electrically connected to the fan. The controller is also electrically connected to an external power supply, a touch screen, a temperature sensor, and a button control module. The external power supply is used to power the controller. The touch screen communicates with the controller to read and write the controller's internal parameters, enabling human-machine interaction. The temperature sensor is used to detect the current ambient temperature, allowing the controller to control and adjust the fan in a timely manner. The button control module is used to switch the controller's control modes, thus adapting to multiple working modes.

[0024] The button control module includes a control panel electrically connected to the controller. The control panel is equipped with an on / off switch, an automatic switching switch, and a manual switching switch. It also features a display component for showing the actual temperature, set temperature, and operating frequency, a regulating component for adjusting the controller's automatic airflow range, and a regulating component for adjusting airflow in manual mode. During operation, the controller uses a temperature sensor to detect the current ambient temperature in real time and displays the current ambient temperature, set temperature, and operating frequency on the control panel display component. When automatic adjustment is required, the user presses the automatic switching switch. In automatic mode, the airflow is automatically adjusted based on the difference between the ambient temperature and the set temperature, with adaptive fan speed adjustment. To manually adjust the airflow, the user presses the manual switching switch and controls the regulating component to control the airflow. Once started, the fan speed remains constant, regardless of the current or set temperature.

[0025] The adjustment component includes a control knob, which is electrically connected to the control panel. In manual control mode, the user can adjust the fan operating frequency and thus the air volume by using the control knob. However, after pressing the automatic switching button, the control knob can no longer adjust the operating frequency.

[0026] The display component includes several digital tubes, which are combined into six figure-eight shaped display blocks. The six display blocks are divided into three groups of display combination blocks. Each group of display combination blocks consists of two display blocks. The three groups of display combination blocks are respectively set at the actual temperature, set temperature, and operating frequency. When the fan is working, the three groups of display combination blocks can respectively display the actual temperature, set temperature, and operating frequency, which is convenient for the operator to view.

[0027] The control panel is symmetrically equipped with setting keys, and adjustment keys are located on both sides of the two setting keys. When it is necessary to limit the fan airflow adjustment range in automatic mode, the user presses the two setting keys at the same time, and then enters the function code parameter setting interface. The user can then change the maximum and minimum frequencies through the two adjustment keys to adjust the airflow control range.

[0028] The control panel features a low-temperature shutdown control button and a power-on automatic start control button. To use, press and hold the manual switch button for 3 seconds; the power-on automatic start indicator will illuminate, indicating that the function is activated. Once activated, the fan will automatically start running upon the next power-on. Press and hold the automatic switch button for 3 seconds; the low-temperature shutdown indicator will illuminate, indicating that the low-temperature shutdown function is activated. Once activated, when the ambient temperature is lower than the set temperature, the fan can be set to run for a specified number of minutes and then stop for a specified number of minutes, cycling through these cycles to periodically remove moisture and ammonia from the farm.

[0029] The control panel and various function prompts are equipped with LED indicator lights. During use, the LED indicator lights at the low temperature shutdown, power-on automatic start, RUN, power, manual / automatic switching, and WIFI functions indicate whether the current state is on. A lit LED indicates that the function is on, and an off LED indicates that the function is off.

[0030] The touchscreen communicates with the controller via an RS-485 communication interface.

[0031] The above embodiments disclose a speed controller for aquaculture fans. A temperature sensor measures the current ambient temperature. In automatic mode, the user presses the automatic switch button, and the fan speed is automatically adjusted based on the difference between the ambient and set temperatures. The fan speed is adaptively adjusted using a PID algorithm. For manual adjustment, the user presses the manual switch button and uses a control knob to adjust the fan's operating frequency, thus regulating the fan speed. Once started, the fan speed remains constant, independent of the current and set temperatures, improving energy efficiency. Pressing and holding the manual switch button for 3 seconds illuminates the power-on automatic start indicator, indicating that the function is activated. Once activated, the fan will automatically start upon the next power-on. Press and hold the automatic switching button for 3 seconds. At this time, the low temperature shutdown light will illuminate, indicating that the low temperature shutdown function has been activated. After this function is activated, when the current ambient temperature is lower than the set temperature, the fan can be set to run for a certain number of minutes and then stop for a certain number of minutes, and this cycle will be repeated to remove moisture and ammonia from the farm at regular intervals. The communication touch screen human-machine interface can monitor the current ambient temperature, modify the set temperature, and set the fan speed.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
