Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse temperature regulation technology, and in particular to a temperature regulation device for agricultural greenhouses. Background Technology

[0002] Currently, crops require specific growing temperatures. In northern regions, temperatures fluctuate significantly with the seasons, severely impacting breeding and crop growth. To provide suitable growing temperatures and produce off-season crops, greenhouse technology is widely used. Greenhouses are typically designed with a plastic film covering a support structure to create a sealed, insulated space, relying on sunlight for internal temperature. However, their drawback is that temperatures inside the greenhouse are very high in summer and insufficient in winter.

[0003] Currently, the general approach is to manually sense the temperature in the greenhouse and then manually adjust the temperature by insulating or ventilating it. Temperature control devices are also used to regulate the temperature. However, when cooling the greenhouse, dust and impurities from the outside can easily enter the device, affecting it and thus impacting subsequent cooling. Furthermore, the device cannot quickly adjust the temperature when raising or lowering it, resulting in untimely temperature changes that negatively affect crop growth.

[0004] Therefore, it is necessary to provide a temperature control device for agricultural greenhouses to solve the above-mentioned technical problems. Utility Model Content

[0009] The housing is equipped with a serpentine heating wire, which is located between the fan blade and the square plate. The electrodes at both ends of the serpentine heating wire pass through and are fixedly connected to the lower side of the housing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] A temperature control device for agricultural greenhouses includes a temperature control module 2, wherein multiple sets of the temperature control module 2 are provided, and the multiple sets of the temperature control module 2 are arranged on both sides of the greenhouse 1.

[0030] The temperature control module 2 includes a blower assembly, which includes a square plate 28. The two ends of the square plate 28 are respectively fixedly connected to the two sides of the inner wall of the housing 21. The central shaft of a bevel gear 27 passes through and is movably connected to the square plate 28. The end of the central shaft of the bevel gear 27 is fixedly connected to the center of the fan blade 29. The bevel gear 27 meshes with a bevel gear 26. The central shaft of the bevel gear 26 passes through and is movably connected to a rectangular plate 25. The rectangular plate 25 is fixedly connected to the square plate 28. The central shaft of the bevel gear 26 passes through and is movably connected to the upper side of the housing 21. The end of the central shaft of the bevel gear 26 is fixedly connected to the output shaft of a motor 24. The motor 24 is fixedly connected to the upper side of the housing 21.

[0031] The housing 21 is provided with a serpentine heating wire 210, which is located between the fan blade 29 and the square plate 28. The electrodes at both ends of the serpentine heating wire 210 pass through and are fixedly connected to the lower side of the housing 21.

[0032] The temperature regulation module 2 further includes an adjustment component, which includes two electric push rods 214. The housings of the two electric push rods 214 are respectively connected to the two sides of the housing 21 by pins. The ends of the telescopic rods of the two electric push rods 214 are respectively connected to the corresponding swing rods 213 by pins. The ends of the two swing rods 213 are respectively connected to the ends of the two central shafts of the baffle 212. The two central shafts of the baffle 212 are respectively movably connected to the two sides of the housing 21.

[0033] The edge of the square frame 22 is fixedly connected to the middle of the inner wall of the housing 21.

[0034] The lower side of the housing 21 is fixedly connected to the edge of the square frame 23.

[0035] Temperature sensor 211 is fixedly connected to the lower side of housing 21.

[0036] One end of the housing 21 is fixedly connected to the edge of the filter plate 215.

[0037] The shell 21 passes through and is fixedly connected to one side of the greenhouse 1.

[0038] Working principle: The two electrodes of the serpentine heating wire 210 are electrically connected to an external power supply, energizing the serpentine heating wire 210. When the device is in use, when the temperature sensor 211 detects that the temperature inside the greenhouse 1 is high, it controls the two electric push rods 214 to start. The extension rods of the two electric push rods 214 extend and drive the corresponding swing rods 213 to swing. The two swing rods 213 drive the baffle 212 to move to the square frame 23, so that the baffle 212 blocks the square frame 23. At this time, the electric push rods 214 are turned off, and then the motor 24 is started. The motor 24 drives the bevel gear 26 to rotate. The bevel gear 26 meshes with the bevel gear 27 to rotate. The bevel gear 27 drives the fan blades 29 to rotate, so that the gas that enters the housing 21 through the filter plate 215 enters the greenhouse 1. The filter plate 215 can filter out dust and impurities in the air, so that the outside gas cools the greenhouse 1.

[0039] Conversely, when the temperature sensor 211 senses that the temperature inside greenhouse 1 is low, the telescopic rod of the control electric push rod 214 retracts, causing the baffle 212 to swing away from the square frame 23 to the square frame 22, so that the baffle 212 blocks the square frame 22. At this time, the external power supply is turned on, so that the serpentine heating wire 210 is energized to heat the air inside the shell 21, thereby raising the temperature inside the shell 21. At the same time, the fan blades 29 blow the hot air inside the shell 21, so that the hot air inside the shell 21 enters the greenhouse 1 through one side opening. The air inside the greenhouse 1 is continuously replenished into the shell 21 through the square frame 23. This cycle continues, raising the temperature inside the greenhouse 1.

[0040] This device can use the temperature regulation module 2 to regulate the temperature inside the greenhouse 1, keeping the temperature inside the greenhouse 1 within a suitable range, which can provide favorable conditions for the growth of crops.

[0041] Beneficial effects: The temperature sensor 211 detects the increase or decrease in temperature inside greenhouse 1, causing the baffle 212 to switch and complete the shading of square frame 23 or square frame 22, thereby cooling or heating greenhouse 1. This device can use the temperature regulation module 2 to regulate the temperature inside greenhouse 1, keeping the temperature inside greenhouse 1 within a suitable range, which can provide favorable conditions for the growth of crops.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
