Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse environment control, and more specifically, to a semi-enclosed greenhouse control system. Background Technology

[0002] Current technology has limited research on semi-enclosed greenhouses. Greenhouse cooling often relies on evaporative cooling systems with fans, but this method limits the distance between the evaporative curtains and the fans to no more than 50 meters; exceeding this distance significantly reduces effectiveness, as conventional fans lack sufficient airflow. This limits the greenhouse length to 50 meters, while planting greenhouses often exceed this length, further hindering the effectiveness of evaporative cooling systems with fans.

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figure 1As shown, a semi-enclosed greenhouse control system is disclosed according to this utility model, including a greenhouse planting area 1 and a semi-enclosed climate chamber 2 located on one side of the greenhouse planting area 1. The semi-enclosed climate chamber 2 is provided with a wet curtain 3 in the middle. The semi-enclosed climate chamber 2 is divided into a first climate space 21 and a second climate space 22 by the wet curtain 3. The second climate space 22 is located below the wet curtain 3, and the first climate space 21 is located above the wet curtain 3. A fan 4 is provided at the lower end of the second climate space 22. The fan 4 is connected to a duct 6 through a duct 5. One end of the duct 6 extends to the end of the cultivation trough of the greenhouse planting area 1. A heating device 7 is also provided in the second climate space 22. One side of the first climate space 21 is provided with a ventilation port 211 communicating with the greenhouse planting area 1, and the other side is provided with a ventilation port 212 communicating with the outside. Several horizontal support rods 8 are provided at the upper end of the greenhouse planting area 1. Several supplementary lights 10 and sprayers 11 are evenly provided on the horizontal support rods 8. The duct 5 is connected to a carbon dioxide supply unit through a branch pipe 9.

[0021] In a specific embodiment of this application, a temperature sensor, a humidity sensor, a light intensity sensor, and a carbon dioxide sensor are installed in the greenhouse planting area 1 to monitor the temperature, humidity, light intensity, and carbon dioxide concentration in the greenhouse planting area 1, and transmit the signals to the control system. The control system controls the corresponding components to regulate the environment within the greenhouse planting area 1. When the temperature in the greenhouse planting area 1 is detected to be too high, the air is cooled by the wet curtain 3 and then discharged into the greenhouse planting area 1 by the fan 4. When the temperature in the greenhouse planting area 1 is detected to be too low, the heating device 7 heats the air and then discharges it into the greenhouse planting area 1 by the fan 4 (if necessary, supplemental lighting 10 can be used to provide heat). When the humidity in the greenhouse planting area 1 is detected to be too low, the sprayer 11 is controlled to spray water mist to increase the humidity. When the light intensity in the greenhouse planting area 1 is detected to be insufficient, the supplemental lighting 10 is controlled to provide supplemental lighting. When the carbon dioxide in the greenhouse planting area 1 is detected to be insufficient, the carbon dioxide supply unit is controlled to supplement carbon dioxide and send it into the greenhouse planting area 1 by the fan 4.

[0022] In a specific embodiment of this application, both vent 1 211 and vent 2 212 are equipped with an electric opening and closing structure, such as an electric opening and closing window driven by a ball screw pair. The automatic opening and closing of vent 1 211 and vent 2 212 is realized according to the corresponding control mode of the control system. An air filter 2111 is provided on the side of vent 1 211 located in the greenhouse planting area 1. An air filter 2121 and a bird and insect net 2122 are provided in sequence on the side of vent 2 212 located in the outside. The bird and insect net 2122 prevents damage to the air filter 2121. The air filter 2111 and the air filter 2121 prevent dust, lint and other debris from entering the semi-enclosed climate chamber 2 and prevent the wet curtain 3 from being blocked.
