Description

Technical Field

[0001] This utility model relates to the field of facility cultivation environment control technology, and in particular to a facility cultivation power-integrated ventilation device. Background Technology

[0002] With the rapid development of modern agriculture, protected cultivation, as a highly efficient agricultural production model, has become an important way to adjust the agricultural industrial structure and increase farmers' income due to its advantages of not being limited by seasons or regions and being able to achieve high-quality and high-yield crops. In the process of protected cultivation, the ventilation system is a core component to ensure the stability of the cultivation environment. Its main functions include removing excess heat from the room, reducing air humidity, replenishing fresh air (especially carbon dioxide), and removing harmful gases (such as ammonia and ethylene), which directly affects the photosynthetic efficiency of crops, the probability of pests and diseases, and the final yield and quality. Currently, ventilation devices commonly used in greenhouse cultivation are mainly divided into two categories: natural ventilation devices (such as skylights and side windows) and mechanical ventilation devices (such as exhaust fans and circulating fans). Natural ventilation devices rely on external wind and indoor-outdoor temperature differences to achieve air exchange. Although they have the advantage of low energy consumption, their ventilation efficiency is greatly affected by the external environment. In windless, high-temperature, or high-humidity weather, they are difficult to meet the needs of crop growth and cannot achieve precise ventilation control in local areas. Mechanical ventilation devices use electric motors to drive fans to force air exchange, and their ventilation efficiency is relatively stable. However, existing mechanical ventilation devices generally have the following shortcomings: Fixed installation location: Most mechanical ventilation devices are directly fixed to the wall or bracket, which can only ventilate a fixed area. They cannot adjust the ventilation range according to the needs of different growth stages of crops or the environmental differences in different areas of the room (such as temperature and humidity gradients, gas concentration gradients). This results in poor environmental uniformity in the cultivation space, and some areas are prone to high temperature and high humidity dead zones, which increases the risk of crop diseases and pests. Lack or insufficient angle adjustment capability: Most of the adjustable ventilation devices rely on manual adjustment, which is cumbersome and cannot respond to changes in the indoor environment in real time. It is difficult to achieve dynamic and precise angle control, and it is impossible to accurately deliver fresh air or airflow to key areas such as the crop canopy, thus reducing the effectiveness of ventilation. Low level of intelligence: Most existing ventilation devices require manual judgment of start / stop or parameter adjustment based on experience, lacking linkage with environmental monitoring equipment. They cannot automatically adjust ventilation intensity, range and angle based on real-time monitored parameters such as indoor temperature, humidity and carbon dioxide concentration, resulting in insufficient timeliness and accuracy of ventilation operation. This may lead to energy waste and may also affect crop growth due to untimely ventilation. Utility Model Content

With the deflection angle adjustment mechanism to adjust the ventilation angle, the ventilation operation can be precisely positioned to any area within the cultivation space, effectively solving the "ventilation dead zone" problem of traditional ventilation devices. Whether it's the differentiated environmental needs of crops at different growth stages or abnormalities in temperature, humidity, or gas concentration in localized areas, the device can respond quickly and make targeted adjustments, ensuring that environmental parameters within the cultivation space are uniform and stable within the suitable range for crop growth. This reduces problems such as poor crop growth and pest infestation caused by environmental fluctuations, significantly improving crop photosynthetic efficiency and final yield and quality. For example, in the vegetable seedling stage, the device can precisely deliver fresh air above the seedbed, preventing damping-off disease caused by localized high temperature and humidity. During the fruiting period of fruits and vegetables, it can precisely supplement carbon dioxide, promoting fruit enlargement and sugar accumulation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Reference Figures 1-2 This utility model provides an integrated electric ventilation device for facility cultivation, comprising: Fixed frame 1, with mounting bracket 2 rotatably connected to the bottom of fixed frame 1; A deflection angle adjustment mechanism is installed on the fixed frame 1 and is used to adjust the angle between the fixed frame 1 and the mounting frame 2. The ventilation mechanism has a horizontally sliding slider 3 connected to the mounting bracket 2, and a vertically sliding mounting rod connected to the slider 3. The ventilation mechanism is mounted on the mounting rod. X-axis displacement assembly, the X-axis displacement assembly is mounted on the mounting bracket 2 and fixed between it and the slider 3, and is used to push the slider 3 to move linearly; The Y-axis displacement assembly is mounted on the fixed frame 1 and is fixed to the mounting rod via the universal coupling 13. Gas detection module, the gas detection module is installed on mounting bracket 2; The control module, deflection angle adjustment mechanism, ventilation mechanism, X-axis displacement component, Y-axis displacement component, and Y-axis displacement component are all connected to the control module.

[0017] When the device is in operation, the gas detection module installed on the mounting frame 2 first collects environmental parameters such as temperature, humidity, carbon dioxide concentration, and harmful gas content in the cultivation space in real time, and transmits the data to the control module in real time. The control module analyzes the received parameters, and if it finds that one or more parameters exceed the preset range suitable for crop growth, it immediately initiates control commands. For areas with abnormal environmental parameters, the control module first sends a signal to the X-axis displacement component, which drives the slider 3 on the mounting frame 2 to slide horizontally, moving the mounting rod and the ventilation mechanism on the mounting rod, which are vertically connected to the slider 3, to move above the target area. At the same time, the control module sends a signal to the Y-axis displacement component, which drives the mounting rod to rise and fall vertically through the universal coupling 13, adjusting the ventilation mechanism to a height suitable for the crop canopy. If it is necessary to adjust the airflow delivery angle, the control module will also activate the deflection angle adjustment mechanism, which drives the mounting frame 2 to rotate relative to the fixed frame 1, further optimizing the ventilation angle of the ventilation mechanism. After the ventilation mechanism is positioned and angled, the control module starts the ventilation mechanism to achieve air exchange in the target area through exhaust or supply air. During the ventilation process, the gas detection module continuously monitors environmental parameters. The control module dynamically fine-tunes the operating status of the X-axis displacement component, Y-axis displacement component, deflection angle adjustment mechanism, and ventilation mechanism according to parameter changes until the environmental parameters return to the preset range. Subsequently, the control module controls each mechanism to stop operating or enter standby mode as needed, waiting for the next parameter monitoring and control command.

[0018] In a further optimized design, a connecting plate 4 is provided between the fixed frame 1 and the mounting frame 2. The two ends of the connecting plate 4 are rotatably connected to rotating shafts, which are rotatably connected to the fixed frame 1 and the mounting frame 2 respectively. Half gears 5 are fixed on the two sets of rotating shafts respectively, and the two sets of half gears 5 mesh with each other.

[0019] The fixed frame 1 and the mounting frame 2 are rotatably connected via a connecting plate 4. The core transmission logic is based on the synergistic effect of "dual rotating shafts + meshing half-gears 5". A set of rotating shafts is fixed to each end of the connecting plate 4. One end of each set of rotating shafts is rotatably connected to the fixed frame 1 and the mounting frame 2 via bearings, allowing the mounting frame 2 to rotate relative to the fixed frame 1 around the rotating shafts. Simultaneously, half-gears 5 are fixed to each of the two sets of rotating shafts, and the two sets of half-gears 5 remain meshed. When the mounting frame 2 is driven by the deflection angle adjustment mechanism, the rotating shaft connected to the mounting frame 2 rotates accordingly, thereby driving the half-gears 5 on its surface to rotate synchronously. Due to the meshing of the two sets of half-gears 5, the rotation of the half-gears 5 on the mounting frame 2 side drives the half-gears 5 on the fixed frame 1 side and the corresponding rotating shaft to rotate slightly via tooth surface transmission, forming a linkage effect of "the mounting frame 2 actively rotating + the connecting plate 4 adapting accordingly". The advantage of this structure is that, through the meshing restriction of the half gear 5, it can ensure that the mounting bracket 2 always maintains a stable relative position with the fixed bracket 1 during rotation, avoiding structural displacement caused by excessive rotation angle or uneven force, while reducing frictional loss at the connection between the rotating shaft and the fixed bracket 1 and mounting bracket 2, thereby improving the stability and service life of the overall rotating structure.

[0020] The scheme is further optimized. The deflection angle adjustment mechanism includes an angle adjustment motor 6, which is fixed on the fixed frame 1. The output shaft of the angle adjustment motor 6 is fixedly connected to a drive gear, and a driven gear is fixed on the rotating shaft. The drive gear meshes with the driven gear.

[0021] The deflection angle adjustment mechanism uses an "angle adjustment motor 6 + gear transmission" as its core drive method to achieve precise control of the deflection angle of the mounting bracket 2. The angle adjustment motor 6 is fixed on the fixed bracket 1, and its output shaft is rigidly connected to the drive gear. A driven gear is fixed on the rotating shaft connected to the mounting bracket 2, and the drive gear and the driven gear are meshed. When the control module issues an angle adjustment command, it outputs a corresponding electrical signal to the angle adjustment motor 6, controlling the motor to start and drive the drive gear to rotate. The drive gear transmits power to the driven gear through tooth surface meshing, causing the driven gear to drive the rotating shaft fixed to it to rotate synchronously. Since the rotating shaft is rigidly connected to the mounting bracket 2, the rotation of the rotating shaft directly drives the mounting bracket 2 to rotate around the rotating shaft relative to the fixed bracket 1, thereby adjusting the deflection angle of the mounting bracket 2 and the ventilation mechanism and gas detection module installed on it. In addition, the angle adjustment motor 6 can adjust the rotation direction of the output shaft (forward or reverse) through the control module to achieve clockwise or counterclockwise deflection of the mounting bracket 2. At the same time, by controlling the motor speed and the number of rotations, the deflection angle of the mounting bracket 2 can be precisely controlled (such as any angle adjustment within the range of 0-90°) to meet the needs of different ventilation directions. Compared with traditional manual or hydraulic adjustment, it has the advantages of fast response speed, high adjustment accuracy and strong controllability.

[0022] Further optimization of the scheme: the ventilation mechanism includes a ventilation pipe 7, which is an L-shaped structure. The inflection point of the ventilation pipe 7 is fixed to the mounting rod. A funnel-shaped cover 8 is fixed to the bottom of the ventilation pipe 7. A corrugated pipe 9 is fixedly connected to the other end of the ventilation pipe. A filter 10 is installed at the end of the corrugated pipe 9. The filter 10 is connected to the ventilation pump through a pipe.

[0023] The air exchange mechanism adopts an integrated structure of "L-shaped ventilation duct 7 + funnel-shaped cover 8 + corrugated pipe 9 + filter 10 + air exchange pump," with the core function of achieving efficient airflow collection, delivery, and purification. The inflection point of the L-shaped ventilation duct 7 is fixed to the mounting rod, ensuring that the duct moves synchronously with the displacement and angle adjustment of the mounting rod. The funnel-shaped cover 8 at the bottom of the duct expands the coverage area for airflow intake / exhaust, allowing for more even delivery of airflow to the crop canopy or collection of air from around the crops, improving ventilation efficiency. The other end of the ventilation duct 7 connects to the corrugated pipe 9. Utilizing the expandable and bendable characteristics of the corrugated pipe 9, it can adapt to the horizontal and vertical displacement of the mounting rod (preventing damage to the duct due to displacement) and flexibly adjust the airflow delivery path. The filter 10 at the end of the corrugated pipe 9 has a built-in filter screen (such as a dust screen or activated carbon filter), which filters the fresh air entering the duct or the indoor air exiting when the air exchange pump is started. The system removes dust, impurities, and harmful microorganisms from the air, preventing pollutants from entering the cultivation space and affecting crop growth, or preventing dust carried by high-humidity indoor air from clogging the air exchange pump. The air exchange pump, as the airflow power source, is connected to the filter 10 through a pipe. When the control module activates the ventilation function, the air exchange pump switches between "inhalation" and "exhaust" modes as needed: during inhalation, fresh outside air is filtered by the filter 10 and then sent into the cultivation space through the corrugated pipe 9, L-shaped pipe, and funnel-shaped cover 8; during exhaust, polluted indoor air (such as high-temperature and high-humidity air, air containing harmful gases) is collected by the funnel-shaped cover 8, filtered through the L-shaped pipe, corrugated pipe 9, and filter 10, and then discharged outdoors by the air exchange pump, thus purifying and refreshing the air in the cultivation space.

[0024] The scheme is further optimized. The X-axis displacement component includes a first cylinder 11, which is fixed on the mounting bracket 2. The output shaft of the first cylinder 11 is fixed to the slider 3.

[0025] Further optimization of the scheme: the Y-axis displacement component includes a second cylinder 12, which is vertically fixed on the fixed frame 1, and the output shaft of the second cylinder 12 is fixed to the top of the universal coupling 13.

[0026] In this embodiment, the electrical components need to be selected according to the actual pairing requirements, but no specific limitations are made in this embodiment.
