Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to an adjustable temperature agricultural greenhouse. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light and heat to pass through, and is used for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield. It is primarily used for cultivating or raising seedlings of warm-season vegetables, flowers, and trees during colder seasons. Greenhouses come in many types, categorized by their roof frame materials, lighting materials, shape, and heating conditions. An existing type of temperature-controlled agricultural greenhouse (Announcement No.: CN219628460U) has exhibited at least the following defects in use:

[0003] The above-mentioned solution uses perforated precast cement slabs as the enclosure structure of the greenhouse, excluding the roof, and uses low-temperature water such as groundwater flowing inside as a heat storage and heat conduction medium. In summer, it removes heat from the greenhouse or stores energy in winter, thus enhancing the heat storage capacity of the greenhouse enclosure structure. However, in actual use, due to radiative cooling, on clear, windless, or slightly windy and dry nights, a large amount of heat is lost from the soil inside the greenhouse, causing the temperature inside the greenhouse to drop lower than the outside temperature, resulting in temperature inversion. Therefore, it is necessary to develop a temperature-adjustable agricultural greenhouse. Utility Model Content

[0004] The main purpose of this invention is to provide an adjustable temperature agricultural greenhouse, which can effectively solve the problems in the background technology.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] An adjustable temperature agricultural greenhouse includes a base frame 302. Two symmetrically distributed portal frames 202 are fixedly connected to the top side of one end of the base frame 302. A set of greenhouse frames 201 are fixedly connected to the top of the other sides of the base frame 302. A greenhouse roof frame 108 is fixedly connected to the top sides of all portal frames 202 and greenhouse frames 201. A side plate 208 is fixedly connected between adjacent greenhouse frames 201 and between adjacent greenhouse frames 201 and portal frames 202. A sliding tube 207 is fixedly connected between the opposite top sides of two portal frames 202. Two sets of sliding rings 206 are slidably connected to the outer edge of the sliding tube 207. The two outer edges of the two sets of sliding rings 206 that are furthest apart are fixedly connected to the corresponding portal frames 202. A curtain 204 is fixedly connected to the bottom side of each set of sliding rings 206. The opposite sides of the two curtains 204 are fixedly connected to the corresponding portal frames 202. A sliding top frame 205 is fixedly connected to the opposite sides of the top outer edges of the two door frames 202. The sliding top frame 205 is slidably connected to the bottom side of the curtain 204 and all the sliding rings 206. The outer sides of the two curtains 204 are connected to each other by multiple evenly distributed connecting strips 203. In this embodiment, the side panel 208 is an insulation board, and the curtain 204 is also provided with an insulation layer, giving the outer frame of the greenhouse a better insulation effect.

[0024] A light-transmitting frame 102 is fixedly connected to the top sides of both ends of the greenhouse roof frame 108. A light-transmitting panel 101 is fixedly connected between the top opposite sides of the two light-transmitting frames 102. A slide rail 103 is fixedly connected to the bottom sides of the two light-transmitting frames 102. A fixed side frame 107 is fixedly connected to both sides of one end of the slide rail 103. A sliding side frame 104 is slidably connected to both sides of the other end of the slide rail 103. A barrier curtain 106 is fixedly connected between the opposite side of each sliding side frame 104 and the corresponding fixed side frame 107. In this embodiment, a traction motor 105 is fixedly connected between the opposite sides of the two sliding side frames 104. The output end of the traction motor 105 extends into the interior of the slide rail 103. Therefore, when the traction motor 105 is running, it will slide inside the slide rail 103, thereby driving the barrier curtain 106 to fold and unfold. During the day, the barrier curtain 106 is folded to allow sunlight to enter the greenhouse through the light-transmitting panel 101, raising the temperature inside the greenhouse. At night, the barrier curtain 106 is unfolded. The barrier curtain 106 is a heat-insulating film that prevents heat from escaping from the greenhouse.

[0025] The top surface of the base frame 302 is flush with the ground. A partition frame 301 is fixedly connected to the outer edge of the bottom side of the base frame 302. The top edge of the partition frame 301 extends beyond the ground, and the space between the outer edge of the base frame 302 and the inner wall of the partition frame 301 is filled with heat insulation material. In this embodiment, the heat insulation material can be polystyrene board, perlite, or straw to prevent heat from the soil from escaping. Multiple evenly distributed heat storage cylinders 303 are fixedly connected to the top side of the base frame 302. All heat storage cylinders 303 are located within the space enclosed by the greenhouse frame 201 and the door frame 202. The inside of the heat storage cylinders 303 is filled with heat storage filler, and the outside of the heat storage cylinders 303 should be coated with heat-absorbing material. The heat storage filler is generally water. During the day, heat is absorbed through the water, and at night, the heat stored in the water is released, allowing the inside of the greenhouse to have a relatively stable temperature.

[0026] It should be noted that this utility model, as a temperature-adjustable agricultural greenhouse, allows the sliding side frame 104 to move, opening the barrier curtain 106 at night to cover the light-transmitting panel 101, preventing heat from being conducted from the light-transmitting panel 101 to the outside. The base frame 302, buried underground, prevents the temperature of the soil in the greenhouse from being conducted laterally to the outside, thereby reducing the rate of radiative cooling and maintaining a relatively stable temperature inside the greenhouse. Furthermore, the heat storage tank 303 releases heat when the greenhouse cools down, preventing temperature inversion.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
