Description
Technical Field
[0001] This utility model relates to the field of acoustic rainfall technology, specifically to a mobile acoustic rainfall induction system. Background Technology
[0002] In arid regions or during seasons of water scarcity, acoustic rainfall induction technology may be an effective means of water replenishment. By promoting rainfall, it can help improve irrigation conditions in farmland and increase crop yields. In ecological restoration projects, acoustic rainfall induction technology may help accelerate vegetation restoration and soil improvement.
[0003] However, existing acoustic precipitation devices are mainly fixed structures, meaning their deployment locations are relatively fixed and cannot be flexibly moved according to research or monitoring needs. This limits the application of the equipment in different locations and environmental conditions. Furthermore, because the equipment is immobile, maintenance or repair may require professionals to travel to the device's location. This not only increases labor costs but may also increase time costs due to remote locations and inconvenient transportation. In addition, in field experiments or special environments, fixed-installation acoustic precipitation devices may not be able to meet monitoring needs due to complex terrain and inconvenient transportation.

[0030] This invention provides a mobile acoustic rainfall induction system, which includes an acoustic rainfall induction device and a moving device 1. The moving device 1 supports the acoustic rainfall induction device. The moving device 1 drives the entire system to move and includes a drive trolley 10, a support platform 11 connected to the rear end of the drive trolley 10, and multiple barriers 12 mounted on the support platform 11. The drive trolley 10 moves the support platform 11 to its destination as needed. The barriers 12 limit and protect the components on the support platform 11, preventing tipping during movement and improving safety.
[0031] The acoustic rain induction device includes an air compressor 2, an acoustic transmitter 3, and an acoustic beam gatherer 4 connected to the outlet of the acoustic transmitter 3. The acoustic beam gatherer 4 includes a gathering tube 41. The air compressor 2 and the acoustic transmitter 3 are respectively mounted on the support platform 11 and are limited by a barrier 12. The air compressor 2 is used to compress air to a high-pressure state. The acoustic transmitter 3 is mounted on the moving device 1 and connected to the air compressor 2, generating an acoustic field that excites water vapor condensation in the clouds. The acoustic beam gatherer is located at the outlet end of the acoustic transmitter 3, focusing the acoustic waves and emitting them in a specified direction. Along the length of the support platform 11, the air compressor 2, the acoustic transmitter 3, and the gathering tube 41 are distributed sequentially. This distribution method allows for efficient use of the space on the support platform 11.
[0032] The mobile device 1 is also equipped with a driving component and a connecting component 40. The sound wave focusing component 4 is hinged to the mobile device 1 via the connecting component 40. The driving component is directly or indirectly connected to the sound wave focusing component 4 to drive the sound wave focusing component 4 to rotate to a set position. Specifically, the focusing tube 41 is hinged to the connecting component 40; the inlet end of the focusing tube 41 is sealed to the outlet end of the sound wave transmitter 3 via a connecting pipe, which is a flexible pipe. By providing a flexible pipe, the angle of the focusing tube 41 can be varied.
[0033] In a specific example, the driving component is an electric actuator 42. The middle part of the cluster tube 41 is connected to the connector 40 via a rotating shaft. The electric actuator 42 is connected to the lower end of the cluster tube 41. The extension and retraction of the electric actuator 42 causes the tilt angle of the cluster tube 41 to change, allowing for real-time adjustment according to actual needs, and sending sound waves to a designated area. The electric actuator 42 has a fixed end and a movable end. The fixed end is fixed to the support platform 11 and located on the side of the cluster tube 41 away from the sound wave transmitter 3. This facilitates the setting of the driving component and avoids interference with the rotation angle of the cluster tube 41.
[0034] By adopting the mobile acoustic rainfall induction system of this application, setting up the mobile device 1, and improving the structure of the acoustic rainfall induction equipment, the mobility of the acoustic rainfall induction equipment is achieved, so that it can be moved flexibly according to research or monitoring needs. At the same time, it can also ensure that the sound waves are emitted to the designated area at a specified angle, thereby improving the rainfall induction effect.
[0035] In the above embodiments, the mobile acoustic rainfall induction system further includes an angle sensor 43 and a control unit 6 communicatively connected to the angle sensor 43. The angle sensor 43 is communicatively connected to the control unit 6. Through real-time detection of the tilt angle of the cluster tube 41 by the angle sensor 43, in conjunction with the controller 60, the angle of the cluster tube 41 can be adjusted in real time to ensure that sound waves are sent to the designated area, thereby improving the rainfall induction effect. The angle sensor 43 is disposed on the connector 40. By setting the angle sensor 43, the rotation angle of the cluster tube 41 can be collected in real time.
[0036] In the aforementioned example, the control unit 6, the air compressor 2, and the sound wave transmitter 3 are communicatively connected. By configuring the control unit 6 to communicatively connect the air compressor 2 and the sound wave transmitter 3, the movable sound wave rain-inducing device can be electrically controlled.
[0037] In the above embodiments, the air compression device 2 includes an air compressor 20, a speed increaser 22 connected to the drive shaft of the air compressor 20 via a high-speed coupling 21, and a drive unit 24 connected to the input shaft of the speed increaser 22 via a low-speed coupling 23. The inlet end of the sound wave transmitter 3 is connected to the outlet of the air compressor 20. The air compressor 20 is communicatively connected to the control unit 6. The air compressor 20 includes a rotor dynamic balancing assembly 201, bearing housing assemblies 202 and an intake cap 203 respectively disposed at both ends of the rotor dynamic balancing assembly 201, an intake casing assembly 204 and a diffuser casing assembly 205 respectively connected to the outside of the rotor dynamic balancing assembly 201, and an exhaust volute 206; it also includes an outer casing 207 and a centrifugal casing 208 disposed outside the rotor dynamic balancing assembly 201. The intake casing assembly 204, outer casing 207, centrifugal casing 208, diffuser casing assembly 205, and exhaust volute 206 are sequentially connected.
[0038] The rotor dynamic balancing assembly 201 operates to allow the intake casing assembly 204 to draw in air from the atmosphere and perform work on the airflow with the help of the blades. The airflow then enters the diffuser casing assembly 205, where it is decelerated and diffused to convert the velocity into static pressure rise. The pressurized gas is then collected through the exhaust volute 206.
[0039] The drive unit 24 uses an electric motor. The rotor dynamic balancing assembly 201 works to make the intake casing assembly 204 draw in air from the atmosphere and use the blades to do work on the airflow, increasing its speed and pressure. The airflow then enters the diffuser casing assembly 205, where it is decelerated and diffused to convert the speed into static pressure increase, further increasing the gas pressure. The pressurized gas is collected through the exhaust volute 206 and then discharged from the exhaust volute 206 to the sound wave emitter 3. The sound wave emitter 3 generates a sound wave field that can excite water vapor condensation in the clouds, disturbing the water vapor molecules and promoting water vapor condensation to form raindrops.
[0040] The sound wave transmitter 3 includes an electroacoustic converter 30, a frequency adjustment module 31, and a diaphragm 32 disposed at the front end of the electroacoustic converter 30 for generating sound waves. An acoustic impedance matching component 5 covers the outer surface of the diaphragm 32 and is attached to the side of the diaphragm 32 facing the direction of sound wave propagation. This enables efficient emission and directional propagation of sound waves, improving the performance and efficiency of the sound wave transmitter 3. The electroacoustic converter 30 is mounted on the support platform 11, and the frequency and intensity of the sound waves are adjusted by the frequency adjustment module 31. The electroacoustic converter 30 and the frequency adjustment module 31 are communicatively connected to the control unit 6. The electroacoustic converter 30 uses a loudspeaker or transducer to convert electrical signals into sound waves. The diaphragm 32 is the vibrating component that generates sound waves. The transmitter converts electrical signals into sound waves of specific frequency and intensity through the electroacoustic converter, and the diaphragm 32 vibrates at a certain frequency.
[0041] In the example above, the acoustic impedance matching component 5 includes several matching membranes 50 stacked together and bonded together. The bonding method is used to achieve the connection strength of the several matching membranes 50.
[0042] As an alternative example, the thickness of each matching diaphragm 50 increases progressively from the side of the acoustic impedance matching assembly 5 that contacts the diaphragm 32. This achieves a gradual transition in acoustic impedance, thereby reducing the reflection of sound waves as they propagate from the diaphragm 32 into the air and improving sound wave transmission efficiency.
[0043] Specifically, the matching membrane 50 is typically composed of materials with different densities and acoustic impedances, such as polymers, foams, or special composite materials. Adjacent matching membranes 50 are bonded together, and the thickness of each set of matching membranes 50 gradually changes, forming a gradual impedance transition. The matching membrane 50 directly covers the outer surface of the vibrating diaphragm 32 of the sound wave transmitter 3, making close contact with the transmitter to reduce the reflection of sound waves from the transmitter into the air and improve the sound wave transmission efficiency.
[0044] By covering the sound wave transmitter 3 with an acoustic impedance matching component 5, the reflection of sound waves from the transmitter into the air is reduced. The control unit 6 is communicatively connected to the air compressor 2 and the sound wave transmitter 3, respectively, to provide intelligent control of the entire device. The sound wave transmitter 3 and the air compressor 20 work together to promote the condensation of water vapor in the clouds into raindrops through sound wave disturbance and compressed air injection. The injection of high-pressure air can significantly increase the speed and efficiency of water vapor condensation, and together with the sound waves, enhance the rain-inducing effect.
[0045] In the above embodiments, the control unit 6 includes a controller 60 and a data processor 61 and a sensor unit 62 that are respectively communicatively connected to the controller 60. The air compressor 20, the sound wave transmitter 3, and the electric push rod 42 are respectively communicatively connected to the controller 60, and the angle sensor 43 is communicatively connected to the data processor 61.
[0046] The sensor unit 62 includes a humidity sensor 620 for measuring air humidity, a temperature sensor 621 for measuring ambient temperature, a barometric pressure sensor 622 for monitoring atmospheric pressure changes, and a wind speed sensor 623 for measuring wind speed and direction. The humidity sensor 620, temperature sensor 621, barometric pressure sensor 622, and wind speed sensor 623 are all communicatively connected to the data processor 61. Each sensor detects a corresponding data signal, which is then transmitted to the data processor 61. The data processor 61 processes the data and sends the signal to the controller 60. The controller 60 then issues action commands to each actuator, which in turn adjusts the corresponding acoustic parameters, thus specifically promoting rainfall, improving rainfall efficiency, and offering convenient and reliable operation.
[0047] Compared with the prior art, this application has the following advantages:
[0048] First, the mobile acoustic rainfall induction system has a reliable structure and good performance. It can be easily deployed and moved to different locations via the mobile device 1, making it suitable for various environments and needs, such as farmland irrigation, urban greening, and dust suppression at construction sites. At the same time, the equipment's portability allows it to quickly respond to rainfall needs in different regions, improving the flexibility and efficiency of rainfall operations.
[0049] Secondly, the acoustic precipitation technology utilizes sound wave energy to promote cloud droplet condensation and precipitation, eliminating the need for chemical agents or consuming large amounts of water, thus aligning with environmental protection principles. Furthermore, this application employs various sensors to monitor environmental and meteorological elements in real time, providing more comprehensive data support for precipitation operations. This allows for the adjustment of corresponding acoustic parameters, enabling targeted precipitation promotion and improved precipitation efficiency. Simultaneously, the angle sensor 43 monitors the tilt angle of the cluster tube 41 in real time, and in conjunction with the controller 60, allows for real-time angle adjustment of the cluster tube 41, ensuring that sound waves are delivered to the designated area and enhancing the precipitation-inducing effect.
