Description

Technical Field

[0001] This utility model relates to the technical field of temperature control equipment in agricultural facilities, and in particular to an automatic greenhouse air circulation device. Background Technology

[0002] In recent years, with the development of modern agriculture, greenhouses have been widely used. To ensure the growth environment of plants, the interior of greenhouses needs to maintain suitable temperature and humidity conditions. However, in actual use, due to the large temperature difference between the inside and outside, uneven airflow distribution is easily formed inside the greenhouse, resulting in excessively high or low temperatures in some areas, which affects the normal growth of crops. In addition, traditional artificial ventilation methods are inefficient, cannot achieve precise control, and are difficult to meet the needs of large-scale planting.

[0003] A search revealed Chinese patent publication number CN218604206U, which discloses an automatic ventilation device and its usage method for Sunshine Rose grape greenhouses. The inner wall of the connecting pipe is equipped with a cooling mechanism. Through the coordinated operation of the components within the cooling mechanism, in hot summer weather, the high-speed rotation of the water jet atomizes the water into droplets. The high-speed rotation of the top fan blades blows these droplets onto the surface of the grapes inside the greenhouse, thereby lowering the temperature of the surrounding environment. The fan blades also expand the water droplet coverage area, further cooling the greenhouse and preventing heatstroke and sunburn in the grapes. This method has the advantages of low cost and high practicality. When the cooling mechanism is working, ventilation holes are opened to allow the fan blades to rotate, drawing outside air into the greenhouse. A ventilation fan then extracts the hot air from the greenhouse, accelerating air circulation and improving the air circulation effect. However, forced ventilation consumes high energy and negatively impacts the equipment's lifespan. Utility Model Content

Fan frames 6 are fixedly connected to the inner walls of each of the multiple air inlet pipes 5. The fan frames 6 support and position the fans 7, ensuring the stability of the fans 7 during rotation. The bottom of each of the multiple fan frames 6 is rotatably connected to the fans 7. The operation of the fans 7 generates a strong airflow, propelling the air to circulate within the device, achieving effective air circulation. A filter screen 13 is installed on the top of each of the multiple fan bases 4. The filter screen 13 filters the air entering the air inlet pipes 5, preventing debris from entering the device and ensuring the cleanliness of the internal air. The top of each of the multiple filters 13 is threaded with screws 14, which are used to fix the filters 13 and facilitate disassembly and cleaning when needed. Multiple support rods 8 are fixedly connected to the top of each of the multiple fan bases 4. The support rods 8 support the solar panels 9, ensuring the solar panels 9 are at a suitable angle to receive sunlight. The top of the multiple support rods 8 on the same side is fixedly connected to the same solar panel 9. The solar panel 9 converts solar energy into electrical energy, providing green energy for the entire device and achieving energy conservation and environmental protection.

The bottom of multiple air inlet pipes 5 are all connected to air guide pipes 11, which transport the airflow generated by the fan 7 to all corners of the greenhouse, realizing the full circulation of air in the greenhouse. The outer walls of multiple air guide pipes 11 are all equipped with heat insulation layers 12, which can effectively reduce the heat loss of the airflow in the air guide pipes 11, maintain the temperature stability in the greenhouse, and provide a suitable environment for plant growth. The outer walls of the greenhouse body 1 are equipped with multiple ventilation window mechanisms 2.

[0041] Specifically, the fan base 4, air inlet pipe 5, fan frame 6 and fan 7 constitute the fan module. The four fan modules are installed at the four corners of the main frame 3 and the air is transported to each corner of the greenhouse through the air duct 11. The solar panel 9 and the battery 10 are combined to form the power module to realize the supply of green energy. When the sunlight shines on the solar panel 9, the generated electricity is stored in the battery 10 for the use of the system.

[0042] See attached document Figure 1 and attached Figure 6The ventilation window mechanism 2 includes a window frame 201. The outer wall of the window frame 201 is fixedly connected to the inner wall of the shed 1. The window frame 201 serves as the installation frame for the ventilation window, providing a fixed foundation for other components and ensuring the stable installation of the ventilation window on the shed 1. Multiple rotating rods 202 are rotatably connected to the inner wall of the window frame 201. The rotating rods 202 can rotate within the window frame 201, providing rotational support for the opening and closing of the window leaf 203. Window leaf 203 is fixedly connected to the outer walls of the multiple rotating rods 202. The window leaf 203 opens and closes through the rotation of the rotating rods 202, thereby controlling the airflow inside and outside the shed. The outer walls of the multiple rotating rods 202 are meshed with the same toothed plate 204. The toothed plate 204, through meshing with the rotating rods 202, converts its linear motion into the circular motion of the rotating rods 202, thus controlling the opening and closing of the window leaf 203. The toothed plate 204 is fixedly connected to the bottom of the unified control mechanism. The spring assembly 205 provides buffer and elastic support for the toothed plate 204, reduces rigid collisions between components, and extends the service life of the mechanism. The outer wall of the toothed plate 204 is fixedly connected to the fixing block 206, which is used to connect the handle 207 for easy operation of the toothed plate 204. The outer wall of the fixing block 206 is rotatably connected to the handle 207, which serves as the operating component. By rotating and moving the handle 207, the operator can drive the toothed plate 204 to move, thereby controlling the opening and closing of the window leaf 203. The operation is convenient. The outer wall of the window frame 201 is fixedly connected to the hook 208, which is used to fix the handle 207 after the window leaf 203 is opened, so that the window leaf 203 remains open and continuously ventilates the greenhouse.

[0043] Specifically, the window frame 201 serves as the basic frame, ensuring that the ventilation window is securely installed on the inner wall of the greenhouse 1. The rotating rod 202 works in conjunction with the window leaf 203 to achieve flexible opening and closing, effectively controlling the airflow inside and outside the greenhouse. The meshing design of the toothed plate 204 and the rotating rod 202 allows for unified control of the opening and closing of the window leaf 203, making the operation more efficient. The hook 208 can fix the handle 207 after the window leaf 203 is opened, maintaining the ventilation state.

[0044] See attached document Figure 1 Appendix Figure 4 and attached Figure 5Warning signs 15 are provided on the outer walls of multiple batteries 10, which clearly and intuitively convey warnings to users. Terminal posts 16 are fixedly connected to the top of each battery 10. These terminals 16, as key electrical connection components, connect to charging lines and power supply lines for devices such as the fan 7, ensuring stable power transmission and normal equipment operation. Two feet 17 are fixedly connected to the bottom of each battery 10, separating them from the surface to prevent moisture from shortening battery life and increasing stability during use. Support legs 18 are installed inside the shed 1, reliably supporting the support rod 19 and the sensor 20 by close contact with the ground inside the shed 1. The support rod 19 is fixedly connected to the top of the support legs 18, and its length and strength accurately support the sensor 20 at the designated height and position inside the shed to meet the requirements of different sensors within the shed. To meet the monitoring requirements of height and location environmental parameters, a sensor 20 is fixedly connected to the top of the support rod 19. The sensor 20 uses precise sensing elements to monitor the temperature and humidity at different heights and locations inside the greenhouse in real time and accurately, providing key data support for the intelligent control of the greenhouse environment. A display screen 21 is set on the outer wall of the sensor 20, which presents the temperature and humidity data monitored by the sensor 20 to the user, making it convenient for the user to check the environmental conditions inside the greenhouse at any time. The outer wall of the greenhouse body 1 is rotatably connected to the greenhouse door 22, which serves as a passage for personnel to enter and exit the greenhouse. A door handle 23 is fixedly connected to the outer wall of the greenhouse door 22, which provides a convenient gripping and force application part for the user, making the operation of opening and closing the greenhouse door 22 easy and convenient. Multiple hinges 24 are fixedly connected to the outer wall of the greenhouse door 22. The hinges 24, through their unique rotating structure, enable the greenhouse door 22 to rotate smoothly around a fixed axis, realizing the opening and closing function of the greenhouse door 22 and ensuring the normal use of the greenhouse.

[0045] Specifically, the battery 10, along with warning signs 15, terminals 16, and feet 17, ensures electrical safety, stable power transmission, and extends service life. The monitoring system, consisting of feet 18, support rods 19, and sensors 20, accurately measures the temperature and humidity at different heights and locations within the greenhouse. Combined with the display screen 21, it allows users to monitor environmental data in real time, providing a basis for intelligent environmental control.

[0046] Working Principle: At the top of the greenhouse 1, the main frame 3 is made of high-strength aluminum alloy, ensuring the stability of the overall structure. Multiple fan holders 4 are fixedly connected to the top of the main frame 3. Each fan holder 4 has an air inlet pipe 5 fixedly connected to its inner wall. The inner wall of the air inlet pipe 5 is then fixedly connected to a fan frame 6. A fan 7 is rotatably connected to the bottom of the fan frame 6. These components together constitute the fan module. Four fan modules are installed at the four corners of the main frame 3. When the fan 7 starts, air enters through the air inlet pipe 5, generating a strong airflow. The bottom of each of the multiple air inlet pipes 5 is connected to a guide pipe 11. The outer wall of the guide pipe 11 is equipped with an insulation layer 12, effectively reducing heat loss. The airflow generated by the fan module is transported to each corner of the greenhouse through the guide pipe 11. The automatic greenhouse air circulation system enables air circulation within the greenhouse. In terms of energy supply, solar panels 9 and batteries 10 are combined to form a power module. Multiple support rods 8 are fixedly connected to the top of multiple fan bases 4, and the same solar panel 9 is fixedly connected to the top of multiple support rods 8 on the same side. Multiple batteries 10 are installed on the top of the greenhouse body 1. When sunlight shines on the solar panels 9, they convert solar energy into electrical energy, which is stored in the batteries 10. The batteries 10 provide stable power support for the fans 7 and the entire air circulation system, achieving a green energy supply that is both environmentally friendly and energy-saving. The entire automatic greenhouse air circulation device can operate efficiently and stably, creating a good air environment for plant growth within the greenhouse.

[0047] Furthermore, when it is necessary to open the window leaf 203, the operator holds the handle 207 and moves it upward. The handle 207 drives the toothed plate 204 to move upward through the fixing block 206. Since the toothed plate 204 meshes with the rotating rod 202, the movement of the toothed plate 204 will drive the rotating rod 202 to rotate clockwise. The rotation of the rotating rod 202 will then drive the window leaf 203 fixed on its outer wall to rotate, thereby realizing the opening action of the window leaf 203. Then, the handle 207 is hung on the hook 208. At this time, the handle 207 is fixed, and the toothed plate 204 is also fixed. The rotating rod 202 and the window leaf 203 remain in the open state, continuously ventilating the greenhouse. When it is necessary to close the window leaf 203, the handle 207 is removed from the hook 208 and moved downward. The toothed plate 204 drives the rotating rod 202 to rotate counterclockwise, and the window leaf 203 closes accordingly. The entire ventilation window mechanism 2 is simple to operate and can flexibly control the ventilation in the greenhouse.
