Description

Technical Field

[0001] This utility model relates to the field of ventilation and cooling equipment technology, and in particular to an electrically controlled ventilation and cooling device. Background Technology

[0002] Many existing ventilation and cooling devices lack precise adjustment methods for controlling airflow, making it impossible to accurately regulate the air volume. For example, some traditional louvered vents can only be adjusted manually by changing the blade angle, and this method usually only allows for a limited number of settings, making it impossible to fine-tune the airflow. Operators can only roughly estimate the airflow, making it difficult to precisely control the airflow to a specific value that meets actual needs, resulting in indoor temperature, humidity, and air quality failing to reach an ideal and stable state.

[0003] Some ventilation devices that use simple electric control typically use ordinary motors without a speed reduction device or only use simple gear transmission. This makes it impossible to precisely control the opening and closing of the vents, which may result in sudden increases or decreases in ventilation volume. The opening and closing of the vents directly affects the ventilation volume, thus causing significant fluctuations in the indoor environment. In some places that are sensitive to temperature and humidity (such as livestock and poultry sheds, laboratories, etc.), this may affect animal growth or experimental results.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, a power-controlled ventilation and cooling device is specially provided to solve the technical problem that current cooling and ventilation devices cannot accurately adjust the ventilation volume. Utility Model Content

[0005] The purpose of this utility model is to provide an electrically controlled ventilation and cooling device, which is particularly suitable for places that require precise control of ventilation volume and cooling using wet curtains, such as livestock and poultry breeding sheds, agricultural greenhouses, and industrial plants, to solve the technical problem that current cooling and ventilation devices cannot accurately adjust the ventilation volume.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A power-controlled ventilation and cooling device includes an outer frame, an inner frame, an electric reducer, a pulley assembly, a hand-cranked winch, a temperature sensor, and a humidity sensor. The inner frame is connected to a wet curtain assembly. A central connecting plate is horizontally arranged in the middle of the inner frame. A first guide plate is rotatably connected to the bottom of the inner frame by a hinge, and a second guide plate is rotatably connected to the top of the central connecting plate by a hinge.

[0008] The electric reducer is connected to a winch and includes a motor and a reducer. The motor is a servo motor or a stepper motor, which facilitates precise control.

[0009] Choosing between servo motors and stepper motors offers high positioning accuracy and torque control capabilities. Stepper motors convert input electrical pulse signals into precise angular displacement; by controlling the number and frequency of pulses, the motor's rotation angle and speed can be precisely controlled. Servo motors, on the other hand, offer higher dynamic response and control precision, enabling closed-loop control and making them suitable for applications requiring higher accuracy. For example, in high-precision control scenarios where the opening and closing angle of the air deflector needs to be accurate to within 1 degree, a servo motor can be selected. For slightly lower precision requirements, around 5 degrees, a stepper motor can be used to convert rotational motion into linear or angular motion: a gear mechanism can be used to convert the rotational motion of the motor reducer into linear or angular rotational motion of the air deflector via a pulley system.

[0010] The pulley assembly includes a first pulley group and a second pulley group. The hand-cranked winch includes a first hand-cranked winch and a second hand-cranked winch. The first pulley group is equipped with a first steel wire rope. One end of the first steel wire rope is connected to a counterweight, and the other end is connected to a first lifting pulley. The left and right ends of the steel wire rope passing through the first lifting pulley are respectively wound around the winch and the first hand-cranked winch. A first connector is provided on the first guide plate. The connector is connected to the first steel wire rope by a connecting steel wire rope.

[0011] The second pulley block is equipped with a second steel wire rope. One end of the second steel wire rope is connected to a counterweight, and the other end is connected to a second lifting pulley. The left and right ends of the steel wire rope passing through the second lifting pulley are respectively wound around a winch and a second hand-cranked winch. A second connector is provided on the second guide plate. The connector is connected to the second steel wire rope by a connecting steel wire rope.

[0012] The inner frame is mounted on the outer frame, and the first pulley block, the second pulley block, the electric reducer, and the hand-cranked winch are fixed on the outer frame.

[0013] The outer frame is the supporting structure of the entire device. Its shape and size can be customized according to the actual needs of the installation site and can be installed inside the wall. The inner frame is the frame for installing the baffle plate and is fixed to the outer frame.

[0014] The air deflector is mounted on the inner frame and can be opened and closed along the hinges of the inner frame. The airflow can be adjusted by changing the opening and closing angle. The air deflector uses a fiberglass panel and EPS foam interlayer as the main material to ensure its heat insulation, heat resistance and corrosion resistance.

[0015] The electric speed reducer is connected to the guide vane and drives its opening and closing motion. The electric speed reducer receives signals from the controller and precisely controls the movement of the guide vane based on the magnitude and direction of the signals. The electric speed reducer has excellent torque output and speed regulation performance, enabling precise control of the guide vane's opening and closing angle.

[0016] A wet curtain assembly, or simply wet curtain, is installed on the air inlet side of the inner frame. When outside air passes through the wet curtain, the moisture evaporates and absorbs heat, thus cooling the incoming air. The wet curtain is made of highly absorbent materials (such as plant fibers or synthetic fibers) to ensure sufficient and evenly distributed water flow, guaranteeing a cooling effect.

[0017] In a preferred embodiment, the inner frame is provided with several connectors around its perimeter, and the inner frame is fixed to the outer frame by means of the connectors and bolts.

[0018] In a preferred embodiment, the connecting wire rope between the first guide plate and the first wire rope is the same length as the connecting wire rope between the second guide plate and the second wire rope.

[0019] In a preferred embodiment, the first pulley group includes a first pulley, a second pulley, a third pulley, a first hanging pulley, a self-counterweight, and a first wire rope that passes sequentially around the top of the first pulley, the bottom of the second pulley, and the top of the third pulley and is connected to the first hanging pulley.

[0020] The first pulley system is the same as the second pulley system.

[0021] In one preferred embodiment, a controller is included, and the electric reducer, temperature controller, and humidity controller are connected to the controller.

[0022] Temperature and humidity sensors are installed in the indoor environment requiring ventilation and cooling to monitor the indoor temperature and humidity in real time and feed the data back to the controller. High-precision digital sensors, such as the DHT22, can be used to ensure the accuracy of the monitoring data.

[0023] The controller receives signals from temperature and humidity sensors and sends control signals to the electric reducer according to a preset control algorithm and user-defined parameters to control the opening and closing angle of the guide vane. The controller can be a microprocessor, such as a single-chip microcomputer (e.g., STM32 series), and has storage, calculation, and signal output functions.

[0024] Working principle:

[0025] Temperature and humidity sensors are installed indoors to collect real-time temperature and humidity data, transmitting this data to the controller. The controller calculates the required ventilation volume based on the user-defined target temperature and humidity range and its built-in control algorithm. The controller then sends a control signal to the electric reducer, which in turn drives the guide vane to adjust its opening angle, thus changing the ventilation volume. When the ventilation volume is adjusted, the airflow through the evaporative cooling pad also changes accordingly, using the evaporative cooling pad to cool the incoming air and regulate indoor temperature and humidity.

[0026] The beneficial effects of this utility model are:

[0027] This solution can precisely control the opening and closing angle of the guide vane through an electric reducer, and can precisely adjust the ventilation volume according to different needs, making the adjustment of ventilation volume more flexible and accurate. It solves the technical problem that current cooling and ventilation devices cannot accurately adjust the ventilation volume, and also improves the accuracy of indoor temperature and humidity control.

[0028] This solution utilizes evaporative cooling pads to cool the incoming air, achieving a synergistic effect of ventilation and cooling. This effectively reduces indoor temperature, improves indoor comfort and production conditions. Combined with temperature sensors, humidity sensors, and controllers, it enables automatic monitoring and intelligent control, reducing manual operation and improving the automation level and work efficiency of the equipment.

[0029] This design incorporates a backup control system. When the electric reducer fails to provide power, manual adjustment can be achieved using a hand-cranked winch, preventing delays in adjusting the bleacher in case of power supply abnormalities or electric reducer malfunctions.
