Description

Rotating Cooling Fan Misting System for Smart Greenhouses The present invention relates to a rotary cooling fan spraying system for a smart greenhouse that can effectively control the temperature inside the greenhouse by uniformly spraying cooling water inside the greenhouse. Smart agriculture is a technology that enhances the efficiency of crop cultivation through automated systems, primarily conducted inside greenhouses. As a space isolated from the external environment, a greenhouse allows for the maintenance of consistent crop growth conditions, offering the advantage of stable cultivation even under diverse climatic conditions. However, when a heatwave occurs in the summer, the temperature inside the greenhouse rises rapidly compared to the outside temperature and reaches a high temperature state. This temperature rise not only has a negative effect on crop growth but, in severe cases, can lead to the death of the crops. As a means to address this issue, various cooling devices have been developed to lower the temperature inside greenhouses. Among these, sprinkler systems are widely used to cool the air by spraying water. Sprinkler systems are adopted in many greenhouses because they can be installed with a relatively simple structure and effectively lower the temperature inside the greenhouse. However, sprinkler systems have the drawback of requiring multiple units to cover a large area within the greenhouse. Since the coverage area of each unit is limited, multiple sprinkler systems must be installed to effectively cool the entire greenhouse, which can lead to increased initial installation costs and complexity in maintenance. In particular, an additional control system may be required to ensure uniform operation between sprinkler systems, and cooling efficiency may decrease due to interference between devices. FIG. 1 is a schematic diagram showing a rotary cooling fan spray system for a smart greenhouse according to a preferred embodiment of the present invention. FIGS. 2 and 3 are schematic diagrams illustrating the state of spraying cooling water inside a smart greenhouse using a rotary cooling fan spraying system for a smart greenhouse according to a preferred embodiment of the present invention. Below, a rotary cooling fan injection system for smart greenhouses will be described in more detail with reference to the drawings. In describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art could obscure the essence of the embodiments disclosed in this specification, such detailed description is omitted. The attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included. In the following description, singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “comprising” or “having” are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Hereinafter, a rotary cooling fan injection system for a smart greenhouse according to a preferred embodiment of the present invention will be described with reference to the attached FIGS. 1 to 3. The rotary cooling fan spraying system for smart greenhouses measures the temperature inside the greenhouse in real time, and when it detects a temperature above a set temperature, it automatically sprays cooling water inside the greenhouse to lower the temperature inside the greenhouse. By spraying the cooling water onto the rotary fan and allowing it to spread over a wide area by the centrifugal force of the rotary fan, it maximizes the cooling area inside the greenhouse. Accordingly, the rotary cooling fan spray system for smart greenhouses can achieve effective cooling of a wider area with a single piece of equipment, and the interior of the greenhouse can be cooled evenly. As shown in FIGS. 1 and 2, a rotary cooling fan spray system for a smart greenhouse may include a storage tank (100), a support frame (200), a hose (300), a cooling unit (400), and a control unit (500). The storage tank (100) is configured to store cooling water and may be provided outside the greenhouse. At this time, the cooling water stored in the storage tank (100) may be spring water or groundwater. Meanwhile, although not shown, the storage tank (100) may include a pump, and the pump may supply the cooling water of the storage tank (100) to the spray nozzle described later. At thi
