[0023] See also Figures 1 to 5 The utility model provides a temperature control device for a fruit and vegetable planting base, including a greenhouse enclosure 1 and a controller 18. The top of the greenhouse enclosure 1 is provided with an arc roof 2, and the greenhouse enclosure 1 plays the role of closing the space and supporting the arc roof 2. The sides of the greenhouse enclosure 1 are relatively provided with U-shaped plates 3, and the U-shaped plate 3 is provided with a semicircular through groove 19. A slide bar 6 is slidably provided in the through groove 19, and one end of the slide bar 6 passes through the through groove 19 and is hinged with a swing rod 7. A support plate 27 is provided on the side of the greenhouse enclosure 1, and the support plate 27 is fixedly installed on the side of the greenhouse enclosure 1 to support and fix the first motor 8. The top of the support plate 27 is provided with a first motor 8, and the first motor adopts a DC stepping motor. The end of the swing rod 7 away from the slide bar 6 is fixed on the output shaft of the first motor 8, and the slide bar 6 is connected with a sunshade 5, and the sunshade 5 is laid on the outer surface of the arc roof 2. The other end of the sunshade curtain 5 is connected to a rolling curtain mechanism, which is arranged on the U-shaped plate 3. A refrigerator 11 is provided on one side of the greenhouse enclosure 1. The refrigerator 11 is connected to the main air duct 15 through a first air inlet pipe 22. The main air duct 15 is arranged in the greenhouse. The first air inlet pipe 22 is provided with a first solenoid valve 20. A plurality of air outlets 16 are evenly arranged on the main air duct 15. An air valve 17 is provided at the end of the air outlet 16. The air valve 17 has the function of adjustable opening. The air outlet volume can be adjusted by adjusting the opening of the air valve 17, thereby realizing precise control and adjustment of the temperature. A column 13 is provided on the ground below the air outlet 16, and a temperature sensor 14 is provided on the top of the column 13. The controller 18 is provided on the inner wall of the greenhouse enclosure 1 and is electrically connected to the refrigerator 11, the electric heating box 10, the first motor 8, the temperature sensor 14, the first solenoid valve 20 and the air valve 17.

[0024] When the temperature control device is working, the controller 18 first detects signals from multiple temperature sensors 14. If it is detected that the temperature is too high, the controller 18 controls the first motor 8 to start through an electrical conductor. The first motor 8 rotates to drive the swing rod 7 to swing, and the swing rod 7 drives the slide bar 6 to move in the through groove 19. The slide bar 6 drives the sunshade 5 to move. The sunshade 5 covers the arc roof 2, which plays a role in shielding sunlight, reducing the intensity of sunlight exposure, and is conducive to lowering the temperature; at the same time, the controller 18 starts the refrigerator 11 and opens the first solenoid valve 20. At this time, the second solenoid valve 21 is in a closed state. The fan of the refrigerator 11 starts and flows the cold air into the main air duct 15 through the first solenoid valve 20 and the first air inlet pipe 22. The cold air passes through the main air duct 15 and enters the air outlet 16 respectively, and finally flows into the greenhouse through the air valve 17, thereby lowering the temperature in the greenhouse and achieving temperature control.

[0025] Preferably, the rolling shutter mechanism includes a rotating drum, a rotating shaft 12 and a second motor 9. The rotating drum is rotatably arranged between the two U-shaped plates 3, and the rotating drum is sleeved on the rotating shaft 12. One end of the rotating shaft 12 is rotatably connected to the U-shaped plate 3, and the other end passes through the U-shaped plate 3 and is driven to the second motor 9. The second motor 9 is arranged on the side of the U-shaped plate 3 and is electrically connected to the controller 18.

[0026] When the sunshade curtain 5 is opened or closed, the controller 18 controls the second motor 9 to rotate accordingly. The rotation of the second motor 9 drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the cylinder to rotate. One end of the sunshade curtain 5 is fixed on the roller 4, so that the roller 4 rolls the sunshade curtain 5 on the roller 4, which is conducive to the storage of the sunshade curtain 5 and avoids the sunshade curtain 5 from being knotted or bent, affecting the normal use of the sunshade curtain 5.

[0027] Preferably, the arc roof 2 is made of transparent acrylic material, and the sunshade 5 is made of flexible black hollow material.

[0028] The arc roof 2 is made of transparent acrylic material, and sunlight can penetrate into the greenhouse through the arc roof 2, which is beneficial to the photosynthesis of fruits and vegetables planted in the greenhouse and promotes the rapid growth of fruits and vegetables. When the sunlight intensity is too strong, the sunshade 5 can block the sunlight and reduce the sunlight intensity, so that the sunlight maintains the optimal light intensity, which is beneficial to the temperature control device to stabilize the temperature in the greenhouse.

[0029] Preferably, it also includes a hot air mechanism, which includes an electric heating box 10, a second air intake pipe 23, a third air intake pipe 24 and a second solenoid valve 21. The electric heating box 10 is located on one side of the greenhouse enclosure 1. One end of the third air intake pipe 24 is connected to the first air intake pipe 22, and the other end is connected to the electric heating box 10. The electric heating box 10 is connected to the main air duct 15 through the second air intake pipe 23. The electric heating box 10, the second solenoid valve 21 and the controller 18 are electrically connected.

[0030] When the temperature control device is working, the controller 18 first detects the signals of the multiple temperature sensors 14. If it is detected that the temperature is too low, the controller 18 controls the first motor 8 to start through the electrical wire. The first motor 8 rotates to drive the swing rod 7 to swing, and the swing rod 7 drives the slide bar 6 to move in the through groove 19. The slide bar 6 drives the sunshade 5 to move, thereby reducing the area covered by the sunshade 5 and increasing the intensity of sunlight, which is conducive to increasing the temperature in the greenhouse; the controller 18 starts the refrigerator 11 but turns off the cooling function of the refrigerator 11 and opens the second solenoid valve at the same time. 21. At this time, the first solenoid valve 20 is in a closed state, and the fan of the refrigerator 11 blows the outside air through the first air inlet pipe 22 into the third air inlet pipe 24. The air enters the electric heating box 10 through the third air inlet pipe 24. The resistance wire in the electric heating box 10 is energized and heats the air. Then the heated air flows into the main air duct 15 through the second air inlet pipe 23. The hot air enters the air outlet 16 through the main air duct 15, and finally flows into the greenhouse through the air valve 17, which increases the temperature in the greenhouse, thereby achieving temperature control.

[0031] Preferably, the geometric axis center of the through slot 19 coincides with the output shaft of the first motor 8 .

[0032] When the sunshade 5 is opened, the first motor 8 rotates to drive the swing rod 7 to make a circular motion around the output shaft as the axis, and the geometric axis of the through slot 19 coincides with the output shaft of the first motor 8, thereby preventing the slide bar 6 from getting stuck. At the same time, the U-shaped plate 3 strengthens the supporting strength, making the sunshade 5 mechanism more stable. The swing rod 7 drives the slide bar 6 to move in the through slot 19, and the slide bar 6 drives the sunshade 5 to move. As the slide bar 6 moves to different positions, the area of ​​the arc roof 2 covered by the sunshade 5 is also different, thereby achieving the function of adjusting the intensity of direct sunlight.

[0033] Preferably, it further comprises a bearing 25 , wherein the bearing 25 is sleeved on the slide rod 6 and slidably disposed in the through grooves 19 on both sides.

[0034] The bearing 25 is installed on the slide rod 6, and the slide rod 6 drives the bearing 25 to move in the through groove 19. The bearing 25 rolls in the through groove 19. The friction between the bearing 25 and the through groove 19 is relatively small, thereby reducing the movement resistance of the slide rod 6, which is conducive to the smooth opening and closing of the sunshade 5.

[0035] Preferably, it also includes a double-door 26, which is arranged on the side of the greenhouse enclosure 1.

[0036] The double-door 26 is the entrance and exit of the greenhouse. When the temperature control device works normally, the double-door 26 is in a normally closed state. The double-door 26 is sealed, which is beneficial to the temperature control of the greenhouse.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
