Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a cooling greenhouse. Background Technology

[0002] A greenhouse is a frame-and-film structure with heat-insulating properties. Its emergence allows people to eat out-of-season vegetables and fruits. Generally, vegetable greenhouses use bamboo or steel frames covered with one or more layers of heat-insulating plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growth of vegetables inside, giving the greenhouse a good temperature regulation and insulation effect.

[0003] Currently, most growers use greenhouses for cultivation. Due to the high summer temperatures, the temperature inside a typical greenhouse can reach 40-50 degrees Celsius or even higher. Such high temperatures are not conducive to the growth of plants inside the greenhouse. Therefore, it is necessary to design a cooling greenhouse to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of difficulty in cooling down greenhouses with high temperatures in the existing technology, and to propose a cooling greenhouse.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling greenhouse includes a main frame and further includes: an "L"-shaped frame fixedly connected to the main frame, wherein an upper covering film is fixedly connected to the "L"-shaped frame, an installation rod is fixedly connected to the main frame, a lower covering film is fixedly connected to the installation rod, and the lower covering film is disposed below the upper covering film; and an infusion pipe fixedly connected to the main frame, wherein a diversion seat is fixedly connected to the infusion pipe, a nozzle is fixedly connected to the diversion seat, and the nozzle is connected to the infusion pipe.

[0007] To improve the water spraying effect of the nozzles, preferably, two sets of nozzles are symmetrically arranged, and the included angle between the two sets of nozzles is 90°-130°.

[0008] To facilitate cooling of the greenhouse, the included angle between the two sets of nozzles is 120°.

[0009] To facilitate rain protection inside the greenhouse, a fixing rod is fixedly connected to the "L"-shaped frame, and the upper covering film is attached to the end face of the fixing rod.

[0010] To facilitate the installation of the main frame, preferably, a base is fixedly connected to the main frame, and two sets of bases are symmetrically arranged.

[0011] To improve the service life of the "L"-shaped frame, preferably, the "L"-shaped frame is made of stainless steel or alloy steel.

[0012] Compared with the prior art, this utility model provides a cooling greenhouse with the following beneficial effects:

[0013] 1. This cooling greenhouse uses gaps between the upper and lower covering films to create skylights, thereby dissipating heat from the interior. On the one hand, it provides effective ventilation, allowing air to circulate, reducing humidity and heat buildup inside the greenhouse, and introducing fresh air to promote healthy plant growth. On the other hand, the extended "L"-shaped frame can also block rainwater, preventing it from entering the greenhouse and thus protecting the plants.

[0014] 2. This cooling greenhouse uses sprinklers to spray water, which can quickly lower the temperature inside the greenhouse. When the water is sprayed on the plants and greenhouse facilities, the water will absorb heat through evaporation, lowering the air temperature and thus effectively reducing the accumulation of heat inside the greenhouse. On the other hand, it can also promote airflow, allowing the hot air to be exchanged with the outside air through the skylights, thereby achieving the purpose of ventilation.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. On the one hand, this utility model can spray water through nozzles to quickly lower the temperature inside the greenhouse, thereby effectively reducing the accumulation of heat inside the greenhouse. On the other hand, it can also drive airflow, allowing hot air to be exchanged with outside air through skylights, thereby achieving the purpose of ventilation. Attached Figure Description

[0021] 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.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Reference Figures 1-4 A cooling greenhouse includes multiple sets of equidistantly arranged stainless steel arc-shaped main frames 1. Fixing rods 4 are fixedly connected to the main frames 1 for limiting and fixing the main frames 1. An "L"-shaped frame 5 is also fixedly connected to the main frames 1, and the "L"-shaped frame 5 is located on one side of the main frames 1. An upper covering film 101 is also covered on the main frames 1, and the upper covering film 101 is attached to the outer wall of the upper part of the main frames 1, extending above the "L"-shaped frame 5. An installation rod 3 is also provided below the "L"-shaped frame 5. The upper cover 301 is also fixedly connected to the upper cover 101, covering the outer wall of the right side of the main frame 1. The "L"-shaped frame 5 extends 50cm outward, so that a gap is created between the upper cover 101 and the lower cover 301 to form a skylight, thereby dissipating heat from the inside. On the one hand, it can provide effective ventilation, allow air to circulate, reduce humidity and heat accumulation in the greenhouse, introduce fresh air, and help the plants grow healthily. On the other hand, the extended "L"-shaped frame 5 can also block rainwater, preventing rainwater from entering the greenhouse, thereby achieving the effect of protecting the plants.

[0025] Additionally, refer to Figure 3 and Figure 4 A base 2 is also provided at the bottom of the main frame 1 to facilitate the installation and positioning of the main frame 1. An infusion pipe 6 is also fixedly connected to the main frame 1, and water is delivered to the infusion pipe 6 through an external water source. A diverter seat 7 is also fixedly connected to the infusion pipe 6, and the diverter seat 7 is connected to the infusion pipe 6. Two sets of symmetrical nozzles 8 are also fixedly connected to the diverter seat 7, and the included angle between the two sets of nozzles 8 is 120°, and the distance between each two sets of nozzles 8 is two meters, so as to increase the spraying range of the nozzles 8, ensure that the plants can fully contact the water source, and also cool the inside of the greenhouse.

[0026] Here, water is sprayed through nozzle 8, which can quickly lower the temperature inside the greenhouse. When water is sprayed on plants and greenhouse facilities, the water will absorb heat through evaporation, lowering the air temperature and thus effectively reducing the accumulation of heat inside the greenhouse. On the other hand, it can also drive airflow, allowing the hot air to be exchanged with the outside air through the skylight, thereby achieving the purpose of ventilation.

[0027] 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.
