Description

Technology Field

[0001] The present invention relates to a sprinkler-based frost prevention device for fruit farms that maximizes user convenience while also maximizing the heating efficiency of the heater. Background Technology

[0002] Methods to prevent frost damage to fruit tree flowers include combustion, blowing, and sprinkling.

[0003] The combustion method requires lighting a fire under the fruit tree, so there is a high risk of fire when the wind blows; the blowing method is not economically viable due to excessive costs; and the sprinkler method cannot be used despite being economically viable because if the water temperature drops below -2°C when using water from an underground well at 15°C, greater damage occurs.

[0004] However, although the hot water sprinkler method is widely used as it is evaluated as the most economical and safest, it has the disadvantage of being a conventional method where its use is limited because the sprinkler season occurs when nighttime temperatures drop, preventing users from sleeping in the early morning and requiring them to heat water using a wood heater and store it in a PE tank.

FIGS. 2 and FIGS. 3 are drawings illustrating a method for supplying hot water to prevent cold damage to fruit farms according to an embodiment of the present invention. Specific details for implementing the invention

[0016] Hereinafter, preferred embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, in describing the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations.

[0017] Additionally, throughout the specification, when a part is described as being 'connected' to another part, this includes not only cases where they are 'directly connected,' but also cases where they are 'indirectly connected' with other elements in between. Furthermore, the description of a component as 'including' means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0018] FIG. 1 is a drawing illustrating a spraying method-based frost prevention device for fruit farms according to one embodiment of the present invention.

[0019] Referring to FIG. 1, the device (110) of the present invention includes a cold water tank (110), a heater (120), a hot water tank (130), a hot water tank (140), a cold and hot water supply device (151, 152, 153), a hot water spray device (160), a sensing device (171, 172), and a control device (180), etc.

[0020] The cold water tank (110) stores cold water such as well water, groundwater, tap water, etc.

[0021] The heater (120) uses gas, oil, electricity, etc. as an energy source to heat the cold water supplied to it, thereby producing high-temperature water of about 70° to 80°.

[0022] The high-temperature water tank (130) stores high-temperature water generated by the heater (120), and the hot water tank (140) mixes the cold water and high-temperature water supplied to it to generate and store hot water having a preset target temperature (e.g., 30° to 40°). At this time, the high-temperature water tank (130) and the hot water tank (140) are made of a material with an insulating function or have an insulating material coated in the internal space so that the current temperature of the high-temperature water and hot water can be maintained for a long time.

[0023] The cold and hot water supply device (151, 152, 153) is equipped with a plurality of flow supply devices installed respectively in the cold water inlet pipe of the heater (120), the cold water inlet pipe and the hot water inlet pipe of the hot water tank (140), and controls the amount of cold water supplied to the heater (120), and the amount of cold water supplied to the hot water tank (140) and the amount of hot water supplied, respectively. At this time, the flow control device may be implemented through at least one of a water pump or an electronic valve, but is not limited thereto.

[0024] The hot water spraying device (160) is implemented with a plurality of spray nozzles (161) distributed over the entire area of ​​the fruit cultivation space and a pipe (162) that supplies hot water to the plurality of spray nozzles (162), thereby spraying hot water in the form of mist to prevent fruit freezing damage.

[0025] The sensing device (171, 172) senses the temperature of the fruit cultivation space and the temperature of the hot water through the first temperature sensor (171) installed in the fruit cultivation space and the second temperature sensor (172) installed in the hot water tank (140).

[0026] The control device (180) determines whether to heat based on at least one of the temperature of the fruit cultivation space and a preset heating schedule. When hot water heating is determined, the heater (120), the hot and cold water supply device (151, 152, 153), and the hot water injection device (160) are controlled to operate according to a preset control protocol to generate hot water with a target temperature value, and then to be injected into the fruit cultivation space.

[0027] In this way, the present invention generates high-temperature water through the heater (120) and then mixes it with cold water to generate hot water, thereby reducing the amount of water that the heater (120) needs to heat. That is, a larger amount of hot water can be generated and supplied with minimal operation of the heater (120), and the heating area relative to the heater capacity can be effectively increased.

[0028] FIGS. 2 and FIGS. 3 are drawings illustrating a method for supplying hot water to prevent cold damage to fruit farms according to an embodiment of the present invention.

[0029] The present invention starts generating and supplying hot water by generating high-temperature water through a heater (120) and mixing it with cold water when the temperature of the fruit cultivation space drops below a preset value or when the current time reaches a preset heating time.

[0030] In particular, in the present invention, as shown in FIG. 2, the heater (120) is continuously operated to supply high-temperature water until the hot water temperature reaches a preset target temperature, thereby allowing the time for the hot water temperature to reach the target temperature to be shortened as much as possible.

[0031] And after the hot water temperature reaches the target temperature, the heater is operated intermittently only when the temperature of the fruit cultivation space drops and the temperature difference from the target temperature exceeds a preset value, so that high-temperature water is generated and supplied only enough to maintain the hot water temperature at the target temperature.

[0032] In addition to controlling the driving cycle of the heater, it is also possible to control the supply ratio of cold water and hot water to the hot water tank (140) according to the temperature difference between the hot water temperature and the target temperature.

[0033] For example, if the hot water temperature is too low and the temperature difference from the target temperature is large, the supply of cold water is reduced and the supply of hot water is increased; and as the temperature difference decreases, the supply of cold water is gradually increased in proportion to this, thereby minimizing the amount of heater driven while shortening the time required to reach the target temperature of the hot water.

[0034] Alternatively, the present invention allows for the adjustment of the amount of hot water supplied according to the temperature difference between the temperature of the fruit cultivation space and the target temperature, as shown in Fig. 3.

[0035] For example, when the weather gets cold and the temperature of the fruit cultivation space drops, the amount of hot water supplied is increased in proportion to this through at least one of the hot water injection time and hot water injection cycle of the hot water injection device (160) so that the temperature of the fruit cultivation space can rise to the target temperature more quickly.

[0036] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. It is understood that various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
