The disclosure relates to a rainmaking device, particularly to an aerial spray rainmaking device.
Water resource is one of the essential resources for living, and in general, the main water sources are stored in reservoirs after collection from rainwater, and some of the water sources are obtained from desalination of sea water or other methods. With increasing water demand for agricultural, industrial and domestic use, reduction of water storage capacity of reservoirs due to sediment accumulation over a long period of time, unstable rainfall or insufficient rainfall due to high-temperature waste gas from industrial plants, water source acquisition becomes more difficult, such that rain making process is required.
The related-art rain making method is to deliver catalyst (moisture absorbing powder, such as sodium chloride and silver iodide) into the atmosphere at high altitude via the method of canon or fireworks to change the cloud property, size and distribution, thereby generating water drops for rain. However, such type of rain making method is applicable to small scope of area, and the raining area cannot be precisely controlled. Moreover, it also requires additional cost to purchase and use catalyst for the generation of rain. Accordingly, there is a need to increase and control the scope of area of rain making while reducing the use of catalyst at the same time.
In view of the above, the inventor seeks to overcome the aforementioned drawbacks associated with the current technology and aims to provide an effective solution through extensive researches along with utilization of academic principles and knowledge.
To accomplish the above object, the disclosure makes widespread clouds in the high-altitude sky be quickly condensed into water droplets to accomplish the function of rainmaking.
To accomplish the above object, the disclosure provides an aerial spray rainmaking device, which includes a container, a water storage assembly, a pump and a spraying assembly. The water storage assembly is disposed in the container and includes a water tank filled with water. One end of the pump communicates with the water tank. The spraying assembly includes a pressure tank and multiple nozzles communicating with the pressure tank. Another end of the pump communicates with the pressure tank. The water is pressured by the pressure tank and is nebulized and sprayed out of the container by each nozzle.
The disclosure further has the following functions. It is advantageous to be transported and moved by using a container as a carrier, may be easily obtained and have strong structure. The pressure tank and each nozzle may pressure the water, and nebulize and spray the water to increase the contact area with the low-temperature clouds. The insulation cover may slow down the heating speed or cooling speed of the water in the water tank, so as to reduce the heating time or cooling time of the temperature regulator to reduce energy consumption. The heating element of the spraying assembly may be used to secondarily heat up the water in the pressure tank to prevent the hot water from cooling down after passing through the pump and the pressure tank, and to maintain the temperature of the hot water when spraying.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
The disclosure provides an aerial spray rainmaking device being carried by an aircraft A, please refer to
The disclosure does not limit the size and shape of the container 10. The container 10 may be of various sizes on the market or may be adjusted according to different needs, as long as the loading effect is achieved. Therefore, the size and shape of the container 10 should not be used as a limitation of this disclosure. The container 10 has an opening 11, and the opening 11 communicates with the outside of the aircraft A. The purpose of using the container 10 is to facilitate transferring when entering and exiting the aircraft A. Also, the container 10 has the advantages of easy acquisition, firm structure, and convenient transportation.
The water storage assembly 20 is disposed in the container 10 and includes a water tank 21 filled with water B. The water B may be hot water or cold water. In some embodiments, the water storage assembly 20 further includes a temperature regulator 22, which has multiple heat conducting elements 221 disposed in the water tank 21. The temperature regulator 22 uses each heat conducting element 221 to heat up or cool down the water B in the water tank 21. In the embodiment, the temperature regulator 22 may be a heater or a refrigerant compressor, whose functions are described below. When the temperature regulator 22 is a heater, it heats up the water B in the water tank 21 and each heat conducting element 221 is a heating bar. When the temperature regulator 22 is a refrigerant compressor, it cools down the water B in the water tank 21 and each heat conducting element 221 is a condensing tube.
The spraying assembly 40 includes a pressure tank 41 and multiple nozzles 42 communicating with the pressure tank 41. Two ends of the pump 30 separately communicate with the water tank 30 and the pressure tank 41, and the pump 30 has a control valve 31 for controlling the communication between the water tank 21 and pump 30. Therefore, after the water B in the water tank 21 is heated or cooled by the temperature regulator 22, it may be pumped into the pressure tank 41 by the pump 30 to be pressured, and then the water B is nebulized and sprayed out of the container 10 by each nozzle 42.
Please refer to
When the temperature is low in winter, the temperature regulator 22 may adopt a heater to heat up the water B in the water tank 21 to a high temperature which is under the boiling point (between, but not limited to, 80° C. and 99° C.). Therefore, when the high-temperature nebulized water B′ is sprayed out of the container 10, it may have a temperature difference with the low-temperature clouds C in the high-altitude sky to obtain the desirable effect of condensation, so as to maximize the rainfall efficiency. When the temperature is high in summer, the temperature regulator 22 may adopt a refrigerant compressor to cool down the water B in the water tank 21 to a low temperature which is above the freezing point (between, but not limited to, 1° C. and 20° C.). Therefore, when the low-temperature nebulized water B′ is sprayed out of the container 10, it may have a temperature difference with the high-temperature clouds C in the high-altitude sky to obtain the desirable effect of condensation, so as to maximize the rainfall efficiency. Also, the spraying assembly 40 further includes a heating element 43. When the temperature regulator 22 adopts a heater, the heating element 43 is used to secondarily heat up the water B in the pressure tank 41 to prevent the water B in the water tank 21, which is heated previously, from cooling down after passing through the pump 30 and the pressure tank 41 to maintain the water B at a high temperature when spraying.
Furthermore, the water storage assembly 20 includes an insulation cover 23 disposed outside the water tank 21 to slow down the cooling speed or heating speed of the water B in the water tank 21 so as to reduce the heating time or cooling time of the temperature regulator 22 to reduce energy consumption.
While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
