Description

Technical Field

[0001] This invention relates to the field of greenhouse temperature control technology, specifically to an agricultural greenhouse temperature control system utilizing solar energy. Background Technology

[0002] With the development of agricultural modernization, the application of agricultural greenhouses is becoming increasingly widespread. Temperature control is a crucial aspect of agricultural greenhouses, directly impacting crop growth and yield. Currently, most agricultural greenhouses rely heavily on traditional energy sources such as coal and oil for temperature control. These energy sources are not only expensive but also pollute the environment. Furthermore, existing agricultural greenhouses suffer from problems in light regulation, such as uneven light distribution and localized excessive or insufficient light, which can affect crop photosynthesis and growth. Therefore, how to utilize solar energy for temperature control in agricultural greenhouses, reduce dependence on traditional energy sources, lower energy costs, and simultaneously improve light utilization efficiency to provide a suitable growing environment for crops is a pressing issue that needs to be addressed in the development of agricultural greenhouses.

[0003] Traditional greenhouse designs may not adequately consider the even distribution of light. Due to factors such as the greenhouse structure and the characteristics of the covering materials, sunlight may be overly concentrated in some areas while being relatively weaker in others. This results in significant differences in the light intensity received by crops in different locations. Some crops may grow slowly due to insufficient light, while others may be damaged by excessive light. Furthermore, the sun's position changes throughout the day, and some existing greenhouses may not be able to effectively track and adjust the angle of sunlight incidence. This leads to situations where different areas within the greenhouse experience insufficient or excessive light at different times of the day, affecting the photosynthetic efficiency of crops.

[0004] Uneven light exposure directly affects the photosynthesis of crops. Photosynthesis is the process by which crops convert light energy into chemical energy, and it is the foundation of their growth and development. If the light exposure is uneven, the photosynthetic efficiency of crops will be reduced, resulting in their inability to fully synthesize organic matter, which will affect their growth rate and yield.

[0005] Combining the above issues, we find that existing systems on the market are difficult to simultaneously avoid these problems during use. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a solar-powered agricultural greenhouse temperature control system. Summary of the Invention

An angle adjuster is fixedly connected to the upper end of the horizontal deflector. A reflector is installed inside the angle adjuster. The angle adjuster reflects sunlight onto the shaded side of the circular canopy by adjusting the angle of the reflector. The circular shed is internally connected to a solar heating mechanism, which includes a solar receiving panel. The solar receiving panel is connected to a converter and an energy storage battery box. The energy storage battery box is electrically connected to a heating water tank. A heating circulation pipe is fixedly connected to the outside of the heating water tank. The heating circulation pipe is located inside the circular shed. One end of the heating circulation pipe is connected to a power pump, which drives the hot water to circulate inside the heating circulation pipe. The light adjustment mechanism, ventilation components, and solar heating mechanism are all controlled by an intelligent control device.

[0010] Preferably, the horizontal steering gear includes an annular seat, which is fixedly connected to the upper part of the movable seat. A first steering motor is fixedly connected inside the annular seat, and a drive rod is fixedly connected to the upper end of the shaft of the first steering motor.

[0011] Preferably, the angle adjuster includes a U-shaped frame, with rotating shafts fixedly connected to both ends of the reflector. The rotating shafts are rotatably connected inside the U-shaped frame, and a second steering motor is fixedly connected to one side of the U-shaped frame. The second steering motor drives the reflector to rotate up and down to adjust the angle.

[0012] Preferably, the ventilation component includes a circular bracket, a ventilation fan is installed inside the circular bracket, and multiple support rods are distributed around the upper circumference of the circular bracket, with protective covers fixedly connected to the tops of the multiple support rods.

[0013] Preferably, the arc-shaped sliding door is slidably connected to the inside of the circular shed, and the intelligent control device controls the opening and closing of the arc-shaped sliding door according to the temperature.

[0014] Preferably, a humidity sensor is installed inside the circular shed, and the humidity sensor is electrically connected to an intelligent control device, which controls the operating time of the ventilation components according to the humidity conditions.

[0015] Preferably, a light sensor is installed inside the circular shed, and the light sensor is electrically connected to an intelligent control device.

[0016] Preferably, the heating circulation pipe is wrapped with an insulation layer to reduce heat loss and improve energy utilization efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention maximizes the use of solar energy.

The intelligent control device automatically adjusts the operating status of each mechanism according to the actual situation inside the greenhouse, so that the environment inside the greenhouse is always kept within a suitable range for crop growth, improving the growth stability and stress resistance of crops.

[0019] 3. The entire system of this invention achieves automated control through sensors and motors, reducing manual intervention, improving work efficiency and management accuracy, and lowering labor intensity.

Furthermore, the system can flexibly adjust the light reflection angle, ventilation, and heating temperature according to different weather conditions and crop growth needs, exhibiting strong adaptability and ensuring normal crop growth in various environments, thus improving the flexibility and reliability of agricultural production.

[0029] The specific implementation of this embodiment is as follows: Solar energy is received by a solar receiving panel 31, converted into electrical energy by a converter, and stored in an energy storage battery box 32.

A humidity sensor monitors the humidity inside the circular shed in real time and transmits the data to the intelligent control device. The intelligent control device controls the operating time of the ventilation component 11 according to the humidity. When humidity is high, the ventilation component 11 operates for an extended period to enhance ventilation and reduce humidity; when humidity is low, the ventilation component 11 operates for a shorter period to reduce moisture discharge. An intelligent control device centrally controls the operation of the light adjustment mechanism 2, ventilation component 11, and solar heating mechanism 3. Based on parameters such as temperature, humidity, and light intensity inside the greenhouse, the device automatically adjusts the operating status of each mechanism to maintain suitable environmental conditions within the greenhouse.
