[0041] figure 1is a view showing the structure of the frost and freeze protection device 1 according to the first embodiment of the present invention. The anti-frost and anti-freezing device 1 utilizes a plurality of columns 101 (columns, telescopic columns), 102 ... (assuming that the columns 101 are erected in the field A, and will be separately described below if there are many), and one of the upper parts 101a of the column 101 One or more first fans 110a (elevated fans), one or more heaters 120 arranged in the lower part 101b of the column 101 or suitable places in the field A and the first sensors arranged near the column 101 and in the upper part 101a 130a (first temperature sensor) and the second sensor 130b (second temperature sensor) arranged in the lower part 101b, one or more for detecting the temperature near the crops 200 in the field A (the temperature of the leaves of the crops 200) The third sensor 130c (third temperature sensor) is constituted.

[0063] figure 2 is a view showing the structure of a frost and freeze protection device 1 according to a second embodiment of the present invention. The anti-frost and anti-freezing device 1 utilizes a plurality of columns 101 erected in the field A, one or more first fans 101a (fans) arranged on the top 101a of the columns 101, and one or more first fans 101a (fans) arranged on the middle part 101c of the columns 101. A second fan 110b (the fan in the middle) and one or more heaters 120 arranged in the lower part 101b of the column 101 or in a suitable place in the field A, and the control of the lower part 101b near the column 101 The sensor is composed of a first sensor 130a, a second sensor 130b, and one or more third sensors 130c for detecting the temperature near the crops 200 in the field A.

[0064] The composition of each structure is according to the above-mentioned first embodiment. In addition, in the second embodiment, the second fan 110b is basically installed...

no. 3 approach

[0074] exist Figure 4 and Figure 5 Among them, the first fan 110a (instead of the second fan 110b) is installed on the upper part 101a of the telescopic column 101. For example, the column 101 can be extended and contracted by the control of the controller. The first fan 110a moves up and down as the column 101 expands and contracts. Figure 4 It shows the state that the first fan 110a is at a high position, Figure 5 The state where the fan 110a is in the middle part 101c is shown. That is, the operation according to the second embodiment is performed with the first fan 101a replaced, so equipment saving and cost saving are realized.

Abstract

The invention provides an anti-frost and anti-freezing apparatus which can solve the difficulty of effectively increasing temperature near crops in an energy-saving manner. For the anti-frost and anti-freezing apparatus, a fan at a high position blows down warm wind from a high place to a low place, and a fan at a low position blows wind at a substantially horizontal direction. A garden field is provided with a structure which has a heater. The fan at the high position is workable only when the temperature at a high place where a thermal inversion layer happens is higher than the temperature near crops. Subsequently, the heater is operated when the temperature near the crops is further lowered. On the contrary, when the temperature at the high place where the thermal inversion layer happens is below the temperature near the crops, the fan at the high position is not operated, and the heater and/or a heater at a low position are/is operated. Warm wind is blown at a substantially horizontal direction so as to prevent frost and freeze injuries.

Description

technical field [0001] The present invention relates to an anti-frost and anti-freeze device for anti-frost and anti-freeze of crops. Background technique [0002] As a countermeasure against frost and frost (frost damage) for crops such as pears, apples, peaches, grapes, and loquats, the air blowing method using a frost-proof fan is simple and commonly used. However, the current natural environment in recent years is extremely diverse depending on the local area or the day, even though it is warm in winter, and the current situation is that there are more and more cases of low temperature conditions. It is indeed beneficial to advance the development of crops in warm winters. However, especially in the occasions that need attention, the current situation is that the period from early April to early May when late frost occurs coincides with the period from germination to young fruit period when crops' low temperature resistance rapidly declines, and when the lowest temperat...
