AI Technical Summary
In strawberry greenhouse cultivation, the airflow velocity and temperature are lower at the end of the air supply duct furthest from the fan, resulting in poor growth of strawberries at that end. At the same time, in extreme weather, the overall airflow temperature inside the duct cannot meet the greenhouse heating requirements.
The heating mechanism, consisting of a sliding air chamber and an electric heater, uses the opening and closing of electric louvers to achieve localized and full-range hot air regulation, thereby enhancing the hot air volume and temperature of the air supply duct.
It achieves rapid localized warming and improved wind-heating effect across the entire area, ensuring the temperature requirements of the strawberry growing environment and adapting to heating needs in extreme weather.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouse cultivation technology, specifically to a temperature control device for strawberry greenhouse cultivation. Background Technology
[0002] Strawberries are a fruit that grows in spring and summer. They require specific temperature and light conditions to thrive. Low temperatures can cause them to not develop properly, so most strawberries are now grown in greenhouses.
[0003] Inside greenhouses, ducted air supply systems are typically installed. Traditionally, a fan output is connected to a bag-type duct, with holes drilled in the outer wall of the duct. An electric heating element heats the airflow from the fan outlet, allowing the hot air to be delivered to various areas inside the greenhouse through the holes in the duct. However, in practical applications, the airflow velocity and temperature are relatively low at the end of the air supply duct furthest from the fan, resulting in poor strawberry growth at that distance. Furthermore, during extreme weather conditions, the overall airflow temperature inside the duct cannot meet the heating needs of the entire greenhouse. Therefore, a temperature control device for strawberry greenhouse cultivation is provided to solve these problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a temperature control device for strawberry greenhouse cultivation, which solves the problem that the airflow velocity and temperature at the end of the air supply duct far from the fan are relatively low, resulting in poor growth of strawberries at the far end. At the same time, in the event of extreme weather, the airflow temperature inside the duct cannot meet the heating needs of the entire greenhouse.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a temperature control device for strawberry greenhouse cultivation, including a duct air supply mechanism, a heating mechanism slidably disposed on the outer surface of the duct air supply mechanism, the heating mechanism including a sliding air chamber and an electric heater installed on the top of the sliding air chamber, the middle part of the sliding air chamber being connected to the duct air supply mechanism, and an electric louvered curtain installed at the bottom of the sliding air chamber;
[0006] The electric venetian blinds open, and the electric heater blows air downwards in a localized area.
[0007] When the electric louvered blinds are closed, the electric heater blows air into the ductwork air supply mechanism.
[0008] Preferably, the duct air supply mechanism includes a rigid air supply pipe and an air outlet hole opened on the outer surface of the rigid air supply pipe. An axial flow fan is installed at one end of the rigid air supply pipe, and an electric heating chamber is installed between the rigid air supply pipe and the axial flow fan.
[0009] Preferably, an open ring is installed in the middle of the sliding air chamber, the open ring is slidably disposed on the outer surface of the air supply rigid pipe, and ventilation openings are provided on both sides of the open ring, the ventilation openings being directly opposite the air outlet.
[0010] Preferably, the top of the air supply duct is provided with a suspension support, which includes a suspension rail and a connecting rod fixedly disposed between the suspension rail and the air supply duct.
[0011] Preferably, a drive seat is slidably provided on the outer surface of the suspension rail, and diagonal tie rods are fixedly provided on both sides of the drive seat. The two sets of diagonal tie rods are respectively fixedly installed at both ends of the sliding air chamber.
[0012] Preferably, the drive seat is internally equipped with a traveling gear, and the top of the suspension rail is provided with a toothed groove, which meshes with the traveling gear.
[0013] Preferably, a drive motor is mounted on the top of the drive base, and a transmission chain is installed between the output end of the drive motor and the traveling gear.
[0014] This utility model discloses a temperature control device for strawberry greenhouse cultivation, which has the following beneficial effects: In use, the heating mechanism moves along the air supply duct to any position, and then the bottom electric louver is opened. At this time, the electric heater blows hot air downwards, forming a negative pressure at the end of the vent, which causes the hot air inside the air supply duct to be drawn to the air outlet at that location, increasing the hot air volume at that location and achieving rapid local heating. At the same time, the electric louver can be closed, and the electric heater is started. The airflow enters the air supply duct through the vent, thereby increasing the air volume and air temperature at other air outlet locations, achieving improved heating effect throughout the entire range.
