Description

Technical Field

[0001] The utility model belongs to the technical field of glass greenhouses, in particular to a heat preservation device in a tempered glass greenhouse. Background Art

[0002] A full glass greenhouse refers to a greenhouse style that uses professional aluminum alloy herringbone profiles and single-layer tempered glass as covering materials on the top. This is also one of the most common glass greenhouse structures. This structure has a simple structure and is relatively economical in cost. The greenhouse's gutter is made of galvanized steel plates bent. The glass greenhouse needs to be heated and insulated during use. Because the glass greenhouse is different from the traditional greenhouse in terms of insulation method and does not require a thermal insulation blanket on top, when heating and insulating the glass greenhouse, it is only necessary to set up a heating and insulation mechanism inside it. Therefore, it is necessary to provide a tempered glass greenhouse internal insulation device.

[0003] Among them, after searching, it was found that there was a patent number CN201920635606.0 which disclosed a thermal insulation device for the glass wall of a smart agricultural greenhouse. This thermal insulation device for the glass wall of a smart agricultural greenhouse can meet the daytime light intensity requirements and can insulate the greenhouse at night. It has a low cost and can be used on a large scale.

[0004] However, after research, it was found that although the device can insulate the walls during use, it cannot regulate the temperature inside the greenhouse during actual use. It can only heat the temperature inside the greenhouse through external light. However, in rainy weather, this method of adjusting the temperature inside the greenhouse reduces the quality of the device during use. At the same time, when the sunlight is strong, the temperature inside the greenhouse is high and the top of the greenhouse cannot be shielded, which reduces the practicality of the device during use. Therefore, a new device is provided to solve this problem. Utility Model Content

After the fixing is completed, when the temperature inside the greenhouse is high in summer or when the external sunlight is strong, the user opens the screw slide rail 4 to move the slider 401 arranged inside. Since the outermost side of the dynamic ring 303 is connected to the slider 401 through a connecting piece, the movement of the slider 401 is used to unfold the shade net to provide shade above the greenhouse, thereby preventing the temperature above the greenhouse from being too high due to direct sunlight, thereby improving the effect of the greenhouse during use. At the same time, the stainless steel slide bar 301 has the characteristic of strong hardness, thereby improving the quality of the slide bar 301 during use. When using another embodiment, the plastic steel slide bar 301 is also The plastic-steel slide bar 301 has the characteristic of strong hardness. At the same time, the plastic-steel slide bar 301 has strong corrosion resistance to concentrated nitric acid with enhanced oxidizing properties, which can prevent the plastic-steel slide bar 301 from being corroded by acidic substances in rainwater when used outdoors. Compared with the stainless steel slide bar 301, the service life and quality are longer and higher. When it is rainy or the outdoor temperature is too low, turn on the electric heating rod 502, and use the electric heating rod 502 to adjust the temperature inside the greenhouse. During the adjustment process, turn on the drive motor 601 to rotate the rotating rod 602 arranged below it. When the rotating rod 602 rotates, the fan plate 603 arranged on the outside diffuses the heat emitted by the electric heating rod 502, thereby maintaining the temperature inside the greenhouse and improving the quality of the device during use.
