Description

Technical Field

[0001] This invention relates to the technical field of cloud interference and rain-enhancing meteorological interference equipment, and particularly to an array-type acoustic rain-enhancing device. Background Technology

[0002] In the current field of meteorological monitoring, cloud interference is often carried out due to regional meteorological needs in order to meet the meteorological operation requirements of increasing or decreasing rainfall. Acoustic rain enhancement equipment is currently the most commonly used cloud intervention and rain enhancement equipment in the industry.

[0003] Specifically, the principle of acoustic rain enhancement equipment is to emit sound waves and use their properties to intervene in the clouds to increase rainfall. Generally, in actual meteorological monitoring, the monitoring system displays instantaneous rainfall, current rainfall, and daily rainfall in its backend. Through statistical analysis, the effectiveness of recent rain enhancement efforts can be determined.

[0004] In current industry applications, most acoustic rain enhancement devices consist of a sound-generating mechanism and a resonant mechanism. The sound-generating mechanism comprises several whistle-type sound generators, while the resonant mechanism consists of multiple adjustable-angle resonant horns. During installation and use, the entire sound-generating mechanism is fixed to the ground or other reliable support. After the device is activated, the whistle-type sound generators emit sound waves, and the resonant horns control the direction, sending the sound waves vertically upwards. The characteristics of sound waves are used to influence the clouds, aiming to promote rainfall. During sound generation, a precise phase controller synchronizes the output waveforms of each sound source. By adjusting the phase, a superposition effect of sound waves can be achieved, thereby optimizing the cloud intervention effect and the final rainfall effect.

[0005] However, although the existing acoustic rain enhancement equipment can meet the basic operating conditions at present, the entire sound-generating mechanism is fixed to the ground in its equipment layout structure. After the equipment is installed, the installation position of the sound-generating mechanism cannot be changed. This results in a relatively simple overall sound propagation effect and poor sound field coverage. It can only achieve cloud intervention operations under single or limited operating conditions, resulting in an unsatisfactory effect on the actual increase in rainfall. This restricts the adaptability of acoustic rain enhancement equipment in practical applications and causes many inconveniences to related meteorological monitoring and rain enhancement operations.

[0006] In view of this, how to optimize the component arrangement of the sound wave rain enhancement equipment so that the working position of its sound generating mechanism can be flexibly adjusted to adjust the corresponding sound field effect, so as to meet the working requirements under different working conditions and improve the working condition adaptability of the sound wave rain enhancement equipment is an important technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide an array-type acoustic rain enhancement device, in which the working position of the sound-generating mechanism can be flexibly adjusted to adjust the corresponding sound field effect, so as to meet the working requirements under different working conditions and improve the working condition adaptability of the acoustic rain enhancement device.

[0008] To solve the above-mentioned technical problems, the present invention provides an array-type acoustic rain enhancement device, including a base, the top surface of the base extending in a horizontal direction, a plurality of resonant mechanisms that can be adjusted in angle being fixedly arranged at the edge of the top surface of the base, and a plurality of sound-generating mechanisms that can be adjusted in angle being movably arranged at the center of the top surface of the base.

[0009] Preferably, the top surface of the base is recessed and provided with a track groove mechanism, and a plurality of sliders are movably arranged in the track groove mechanism. The sound-generating mechanism is a whistle-type sound generator that is linked to the sliders in a one-to-one correspondence. A plurality of node positioning mechanisms are fixedly arranged in the track groove mechanism. The node positioning mechanisms can be adapted to the sliders to limit or release the sliders in the horizontal direction.

[0010] Preferably, the track groove mechanism includes an outer ring groove that extends circumferentially and is connected end to end, and a central groove located at the center of the top surface of the base. The central groove and the outer ring groove are arranged concentrically. The track groove mechanism also includes a plurality of straight guide grooves connecting the central groove and the outer ring groove. The straight guide grooves extend radially along the outer ring groove, and each of the straight guide grooves is evenly distributed at equal angles along the circumference of the outer ring groove.

[0011] The node positioning mechanism is provided one-to-one in the central groove, at the junction of the central groove and the straight guide groove, and at the junction of the straight guide groove and the outer ring groove.

[0012] Preferably, the bottom of the slider is provided with a universal wheel that rolls in cooperation with the bottom inner wall of the track groove mechanism.

[0013] Preferably, the slider is made of magnetic material, and the node positioning mechanism is a positioning magnetic sheet fixedly disposed on the inner wall of the track groove mechanism, wherein the positioning magnetic sheet can magnetically engage with the slider.

[0014] Preferably, a tapering guide section is provided at the groove opening where the straight guide groove connects to the central groove and at the groove opening where the straight guide groove connects to the outer ring groove, and the horizontal width of the tapering guide section is smaller than the horizontal width of the straight guide groove;

[0015] The horizontal width of the outer ring groove is equal to the horizontal width of the straight guide groove, and the horizontal width of the central groove is not less than the horizontal width of the straight guide groove.

[0016] Preferably, the number of straight guide slots is 6, and the central angle between two adjacent straight guide slots is 60°.

[0017] Preferably, the sound-generating mechanism includes a sound-generating rotary transmission box linked to the top of the slider, a sound-generating rotary motor is provided inside the sound-generating rotary transmission box, the output shaft of the sound-generating rotary motor is arranged vertically and extends from bottom to top of the sound-generating rotary transmission box, and a turntable is provided above the sound-generating rotary transmission box, extending horizontally and linked to the output shaft of the sound-generating rotary motor;

[0018] A sound-generating bracket is linked to the turntable, and the sound-generating bracket is equipped with the whistle-type sound generator and the sound-generating pitch motor. The output shaft of the sound-generating pitch motor is arranged in the horizontal direction and is linked to the whistle-type sound generator to drive the whistle-type sound generator to reciprocate around the axis of the output shaft of the sound-generating pitch motor.

[0019] Preferably, the width of the sound-generating bracket is greater than the width of the inner groove of the track groove mechanism.

[0020] Preferably, the base is a cuboid structure with a square top surface. Positioning seats are provided at the four corners of the top surface of the base. A resonant rotary transmission box is fixedly connected to the positioning seats. A resonant rotary motor is installed inside the resonant rotary transmission box. The output shaft of the resonant rotary motor is arranged vertically and extends from bottom to top of the resonant rotary transmission box. A resonant bracket is provided above the resonant rotary transmission box and is linked to the output shaft of the resonant rotary motor.

[0021] The resonant mechanism is a resonant horn mounted on the resonant bracket. A resonant pitch motor is also mounted on the resonant bracket. The output shaft of the resonant pitch motor is arranged in a horizontal direction and is linked to the resonant horn to drive the resonant horn to reciprocate around the axis of the output shaft of the resonant pitch motor.

[0022] Compared to the aforementioned background technology, the array-type acoustic rain enhancement device provided by this invention, during operation, can flexibly move each sound-generating mechanism to an appropriate position on the top surface of the base to meet the rain enhancement needs under different working conditions. This adjusts the array layout formed by the coordinated operation of the various sound-generating mechanisms, thereby achieving the layout effect of the sound field formed by the coordinated operation of the various sound-generating mechanisms. Combined with the coordinated operation of various resonant mechanisms, the propagation direction of the sound field formed by the sound-generating mechanisms is adjusted and influenced from the outside, thereby intervening in the cloud layer corresponding to the current meteorological environment, thus meeting the rain enhancement needs under the current working conditions. When the meteorological environment changes and the cloud layer state changes accordingly, each sound-generating mechanism can be moved to a new working position to readjust the array layout of the various sound-generating mechanisms, thereby readjusting the sound field. Combined with the coordinated operation of various resonant mechanisms, the cloud layer intervention effect of the array-type acoustic rain enhancement device is adjusted accordingly to match the rain enhancement needs under the current meteorological environment. Therefore, the array-type acoustic rain enhancement device can adjust the working position of the sound-generating mechanism according to changes in meteorological environment and working conditions, thereby adjusting the corresponding sound field effect to match the cloud interference requirements under different working conditions and meet the rain enhancement operation needs under different working conditions. This significantly improves the working condition adaptability of the array-type acoustic rain enhancement device, making its operation and use more convenient and efficient.

[0023] In another preferred embodiment of the present invention, a track groove mechanism is recessed on the top surface of the base, and a plurality of sliders are movably disposed within the track groove mechanism. The sound-generating mechanism is a whistle-type sound generator that is linked to each slider in a one-to-one correspondence. A plurality of node positioning mechanisms are fixedly disposed within the track groove mechanism. The node positioning mechanisms can be adapted to the sliders to limit or release the sliders in the horizontal direction. The sliders can provide reliable structural support for the whistle-type sound generator, and by using the sliders as direct engaging components with the track groove mechanism, they can provide a certain degree of structural protection for the whistle-type sound generator, preventing the track groove mechanism and its associated moving components from interfering with or causing other adverse effects on the main structure of the whistle-type sound generator. In actual operation, each node positioning mechanism can serve as a temporary positioning and coordination mechanism for each slider, thereby limiting each slider to the corresponding position of the node positioning mechanism. This enables the positioning and arrangement of the slider and the whistle-type sound generator located on the slider, meeting the corresponding array arrangement requirements of the sound generator, ensuring the positioning accuracy and operational stability when implementing sound wave intervention operations on the cloud layer. After the current operation is completed, the slider only needs to be moved away from the currently matched node positioning mechanism to implement the next array arrangement and corresponding cloud intervention and rain enhancement operations.

[0033] The core of this invention is to provide an array-type acoustic rain enhancement device. The working position of the sound-generating mechanism of this array-type acoustic rain enhancement device can be flexibly adjusted to adjust the corresponding sound field effect, so as to meet the working requirements under different working conditions and improve the working condition adaptability of the acoustic rain enhancement device.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted in advance that, in this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Furthermore, in this invention, unless otherwise expressly specified and limited, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0037] In addition, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" for the first feature and the second feature include the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0038] In specific implementation methods, such as Figure 1 As shown, the array-type acoustic rain enhancement device provided by the present invention includes a base 11, the top surface of the base 11 extends in the horizontal direction, a plurality of resonant mechanisms that can be adjusted in angle are fixedly arranged at the edge of the top surface of the base 11, and a plurality of sound-emitting mechanisms that can be adjusted in angle are movably arranged at the center of the top surface of the base 11.

[0039] During specific equipment operation, to meet the rain enhancement needs under different working conditions, each sound-generating mechanism can be flexibly moved to an appropriate position on the top surface of the base 11. This adjusts the array layout formed by the coordinated operation of the various sound-generating mechanisms, thereby achieving the layout effect of the sound field formed by the coordinated operation of the various sound-generating mechanisms. Combined with the coordinated operation of various resonant mechanisms, the propagation direction of the sound field formed by the sound-generating mechanisms is adjusted and influenced from the outside, thereby intervening in the cloud layer corresponding to the current meteorological environment, thus meeting the rain enhancement needs under the current working conditions. When the meteorological environment changes and the cloud layer state changes accordingly, each sound-generating mechanism can be moved to a new working position to readjust the array layout of the various sound-generating mechanisms, thereby readjusting the sound field. Combined with the coordinated operation of various resonant mechanisms, the cloud layer intervention effect of the array-type sound wave rain enhancement equipment is adjusted accordingly to match the rain enhancement needs under the current meteorological environment. Therefore, the array-type acoustic rain enhancement device can adjust the working position of the sound-generating mechanism according to changes in meteorological environment and working conditions, thereby adjusting the corresponding sound field effect to match the cloud interference requirements under different working conditions and meet the rain enhancement operation needs under different working conditions. This significantly improves the working condition adaptability of the array-type acoustic rain enhancement device, making its operation and use more convenient and efficient.

[0040] It is easy to understand that, considering the typical operating conditions and the difficulty of component manufacturing in most cases, the base 11 is generally a cuboid structure with a rectangular flat top surface to optimize the assembly alignment accuracy and array arrangement effect of each sound-generating mechanism and resonant mechanism. Of course, in practical applications, a cylindrical structure with a circular flat top surface or other three-dimensional structures with a flat top surface can also be used as the specific application type of the base 11. The operator can flexibly select and adjust the specific shape of the base 11 according to the actual operating conditions and application requirements. In principle, any shape that can meet the actual application needs of the array-type acoustic rain enhancement device is acceptable.

[0041] Furthermore, considering current industry practices, the sound-generating mechanism in this solution is preferably a whistle-type sound generator 12, while the resonant mechanism is preferably a resonant horn 13. For ease of understanding, the following detailed embodiments will use the whistle-type sound generator 12 and the resonant horn 13 as specific application devices to illustrate the solution. Of course, in practical applications, other devices capable of achieving the corresponding functions can be used to replace the whistle-type sound generator 12 and the resonant horn 13 as the specific application types of the sound-generating and resonant mechanisms. In principle, any device that can meet the practical application needs of the array-type sound wave rain enhancement device is acceptable.

[0042] Specifically, the top surface of the base 11 is recessed and provided with a track groove mechanism. Several sliders 121 are movably arranged in the track groove mechanism. The sound-generating mechanism is a whistle-type sound generator 12 that is linked to the sliders 121 in a one-to-one correspondence. Several node positioning mechanisms are fixedly arranged in the track groove mechanism. The node positioning mechanisms can be adapted to the sliders 121 to limit or release the sliders 121 in the horizontal direction.

[0043] The slider 121 provides reliable structural support for the whistle-type sound generator 12. As a direct mating component with the track groove mechanism, the slider 121 provides structural protection for the whistle-type sound generator 12, preventing interference or other adverse effects on its main structure from the track groove mechanism and its associated moving components. In actual operation, each node positioning mechanism serves as a temporary positioning and mating mechanism for each slider 121, limiting each slider 121 to its corresponding alignment position with the node positioning mechanism. This achieves the positioning and arrangement of the slider 121 and the whistle-type sound generator 12 located on it, meeting the corresponding array arrangement requirements of the sound generator mechanism. This ensures the positioning accuracy and operational stability during sound wave intervention operations on clouds. After the current operation is completed, simply removing the slider 121 from its currently matched node positioning mechanism allows for the next array arrangement and corresponding cloud intervention and rain enhancement operations.

[0044] Specifically, such as Figure 2 As shown, the track groove mechanism includes an outer ring groove 111 that extends in a circular direction and is connected end to end, and a central groove 112 located at the center of the top surface of the base 11. The central groove 112 and the outer ring groove 111 are arranged concentrically. The track groove mechanism also includes several straight guide grooves 113 that connect the central groove 112 and the outer ring groove 111. The straight guide grooves 113 extend radially along the outer ring groove 111, and each straight guide groove 113 is evenly distributed at equal angles along the circumference of the outer ring groove 111. In this way, the straight guide grooves 113 cooperate to form a multi-groove structure layout that is radially arranged around the central groove 112.

[0045] Inside the central groove 112, at the junction of the central groove 112 and the straight guide groove 113, and at the junction of the straight guide groove 113 and the outer ring groove 111, node positioning mechanisms are respectively provided one by one. In this way, by using each node positioning mechanism to form a positioning node at the junction between two adjacent grooves, when the slider 121 is moved to the corresponding positioning node, the node positioning mechanism can reliably limit and temporarily fix the slider 121, so as to reliably limit the working position of the whistle-type sound generator 12 arranged on the slider 121. Thus, after each slider 121 is arranged at the node positioning mechanism at the corresponding position, the whistle-type sound generators 12 located on each slider 121 can cooperate to form an array arrangement structure that can meet the current working conditions. If the current rain enhancement operation is completed and the cloud intervention and rain enhancement operation needs to be matched for the next operation, the sliders 121 can be released from the current limit adaptation node positioning mechanism to restore the sliders 121's mobility. This allows the sliders 121 to be moved to the next arrangement position along the corresponding slots of the track groove mechanism. The corresponding node positioning mechanism at the next arrangement position can then be used to re-limit and temporarily fix the sliders 121, thus completing the array structure layout of the whistle-type sound generator 12 for the next operation.

[0046] More specifically, the bottom of the slider 121 is provided with a caster wheel 122 that rolls with the inner wall of the bottom of the track groove mechanism. The caster wheel 122 enables the slider 121 to move more smoothly in each groove of the track groove mechanism, thereby further improving the movement efficiency of the slider 121 and making the working position adjustment and array structure layout of the whistle-type sound generator 12 more precise and efficient.

[0047] Accordingly, the node positioning mechanism can be a limiting plate protruding from the inner wall of each groove of the track groove mechanism at a corresponding position, so that when the slider 121 moves to the corresponding position, the limiting plate can engage with the slider 121 or the caster 122 to limit and temporarily fix the slider 121. It is easy to understand that the limiting plate is preferably arranged on the bottom inner wall of the groove to reliably match the caster 122 and avoid adversely affecting the movement path of the slider 121; in addition, the protrusion of the limiting plate relative to the inner wall of the groove should not be too large, so that the slider 121 can smoothly pass over the limiting plate when it needs to be released, and thus continue to move to the next target position.

[0048] In addition, the node positioning mechanism can also be a positioning magnetic sheet 114 fixedly set on the inner wall of the track groove mechanism, and the slider 121 is made of magnetic material so that the positioning magnetic sheet 114 can magnetically engage with the slider 121. Thus, when the slider 121 moves to the target position, the positioning magnetic sheet 114 at the target position can reliably attract the slider 121 to the current position, so as to ensure that the working position of the whistle-type sound generator 12 remains constant during subsequent rain enhancement operations. When it is necessary to move the slider 121 to the next working position, only an appropriate pushing force needs to be applied to overcome the magnetic attraction between the positioning magnetic sheet 114 and the slider 121, so as to drive the slider 121 to continue to move smoothly.

[0049] It should be understood that in practical applications, the movement of slider 121 can be manually pushed or pulled by staff, or it can be achieved by a robotic arm or other motion mechanism that can provide stable force and has flexible position adjustment.

[0050] On the other hand, constricting guide sections 115 are respectively provided at the groove openings where the straight guide groove 113 connects to the central groove 112 and at the groove openings where the straight guide groove 113 connects to the outer ring groove 111. The horizontal width of the constricting guide section 115 is smaller than the horizontal width of the straight guide groove 113; the horizontal width of the outer ring groove 111 is equal to the horizontal width of the straight guide groove 113, and the horizontal width of the central groove 112 is not less than the horizontal width of the straight guide groove 113. In this way, the constricting guide section 115 can be used to form a moderately narrowed guiding structure at the groove openings of each groove, so as to further optimize the limiting effect of the slider 121 at each node positioning mechanism, thereby preventing the slider 121 from loosening or misaligning at the node positioning mechanism during the rain enhancement operation, thus further ensuring the positioning accuracy and working stability of each whistle-type sound generator 12.

[0051] In practical applications, considering the need for adaptability to various operating conditions and the difficulty of component placement in most cases, such as Figure 2As shown, there are 6 straight guide slots 113, and the central angle between two adjacent straight guide slots 113 is 60°. Correspondingly, there can be 3 sliders 121. In specific operation, when two sliders 121 are located at the node positioning mechanism where two adjacent straight guide grooves 113 intersect with the outer ring groove 111, and another slider 121 is located at the node positioning mechanism in the central groove 112, the three whistle-type sound generators 12 on these three sliders 121 cooperate to form an equilateral triangle array; when the three sliders 121 are located at the node positioning mechanism where three non-adjacent straight guide grooves 113 intersect with the outer ring groove 111, the three whistle-type sound generators 12 on these three sliders 121 cooperate to form a regular hexagonal array; when two sliders 121 are located at the node positioning mechanism where two straight guide grooves 113 intersect with the outer ring groove 111 on the same diameter line collinear with the outer ring groove 111, and another slider 121 is located at the node positioning mechanism in the central groove 112, the three whistle-type sound generators 12 on these three sliders 121 cooperate to form a linear array. Therefore, only three sliders 121 are needed in conjunction with a track groove mechanism with six straight guide grooves 113 to realize various different types of array arrangements, thereby achieving a relatively good sound field coverage effect and meeting the needs of cloud intervention and rain enhancement operations under various working conditions.

[0052] Of course, in practical applications, the number of straight guide slots 113, the central angle between two adjacent straight guide slots 113, the spacing, and the number of adapted sliders 121 can be flexibly selected and adjusted according to actual working conditions and application requirements. In principle, any method that can meet the actual application needs of the array-type acoustic rain enhancement device is acceptable.

[0053] Furthermore, such as Figure 3 As shown, the sound-generating mechanism includes a sound-generating rotary transmission box 123 linked to the top of the slider 121. A sound-generating rotary motor 124 is housed within the sound-generating rotary transmission box 123. The output shaft of the sound-generating rotary motor 124 is arranged vertically and extends upwards from the top of the sound-generating rotary transmission box 123. Above the sound-generating rotary transmission box 123, a turntable 125 extends horizontally and is linked to the output shaft of the sound-generating rotary motor 124. A sound-generating bracket 126 is linked to the turntable 125. A whistle-type sound generator 12 and a sound-generating pitch motor 127 are mounted on the sound-generating bracket 126. The output shaft of the sound-generating pitch motor 127 is arranged horizontally and linked to the whistle-type sound generator 12, driving the whistle-type sound generator 12 to reciprocate around the axis of the output shaft of the sound-generating pitch motor 127.

[0054] During operation, the start / stop and reversible rotation of the sound-generating rotary motor 124 drives the turntable 125 to rotate at an appropriate angle, thereby causing the sound-generating bracket 126 to rotate synchronously. This allows for adjustment of the rotation angle of the counter-rotating whistle-type sound generator 12 around its vertical axis. Simultaneously, the start / stop and reversible rotation of the sound-generating pitch motor 127 drives the counter-rotating whistle-type sound generator 12 to rotate at an appropriate angle around its horizontal axis, thus adjusting its pitch angle. In this way, the coordinated action and cooperation of the sound-generating rotary motor 124 and the sound-generating pitch motor 127 enable multi-directional adjustment of the sound wave emission angle of the counter-rotating whistle-type sound generator 12. This significantly improves the working angle adjustment range of the whistle-type sound generator 12, further optimizing the overall adaptability of the array-type sound wave rain enhancement equipment to meet the needs of cloud intervention and rain enhancement operations under different working conditions.

[0055] Generally, the sound-generating bracket 126 is a U-shaped bracket composed of three panels on the bottom and sides, as shown in the figure, to provide sufficient adjustment space for the pitch movement of the whistle-type sound generator 12 and avoid interference or obstruction to the main structure of the whistle-type sound generator 12. Of course, in practical applications, a rod-type or box-type bracket structure can also be used as the specific structural form of the sound-generating bracket 126, but it is necessary to ensure that the whistle-type sound generator 12 has sufficient angle adjustment space.

[0056] Furthermore, the width of the sound-generating bracket 126 is greater than the width of the inner groove of the track groove mechanism. This effectively prevents the sound-generating bracket 126 from sinking into the grooves of the track groove mechanism, thereby avoiding interference or obstruction to the movement of the slider 121 within the grooves. This ensures that the sound-generating bracket 126 and the whistle-type sound generator 12 mounted thereon are always above the main structure of the track groove mechanism, guaranteeing that the whistle-type sound generator 12 has sufficient working space.

[0057] Additionally, see Figure 1 As shown, the base 11 is a cuboid structure with a square top surface. Positioning seats 131 are correspondingly provided at the four corners of the top surface of the base 11. A resonant rotary transmission box 132 is fixedly connected to the positioning seats 131. (Refer to reference...) Figure 4As shown, a resonant rotary motor 133 is installed inside the resonant rotary transmission box 132. The output shaft of the resonant rotary motor 133 is arranged vertically and extends from bottom to top of the resonant rotary transmission box 132. A resonant bracket 134 is installed above the resonant rotary transmission box 132 and is linked to the output shaft of the resonant rotary motor 133. The resonant mechanism is a resonant horn 13 installed on the resonant bracket 134. A resonant pitch motor 135 is also installed on the resonant bracket 134. The output shaft of the resonant pitch motor 135 is arranged horizontally and is linked to the resonant horn 13 to drive the resonant horn 13 to reciprocate around the axis of the output shaft of the resonant pitch motor 135.

[0058] During operation, the resonant rotary motor 133 is started, stopped, and rotated in both directions to drive the resonant bracket 134 to rotate at appropriate angles, thereby adjusting the rotation angle of the resonant horn 13 around its vertical axis. Simultaneously, the resonant pitch motor 135 is started, stopped, and rotated in both directions to drive the resonant horn 13 to rotate at appropriate angles around its horizontal axis, thereby adjusting its pitch angle. Thus, by utilizing the coordinated action and cooperation of the resonant rotary motor 133 and the resonant pitch motor 135, multi-directional adjustment of the sound wave emission angle of the resonant horn 13 is achieved, significantly improving the working angle adjustment range of the resonant horn 13. This further optimizes the overall adaptability of the array-type acoustic rain enhancement equipment to meet the needs of cloud intervention and rain enhancement operations under different working conditions.

[0059] Based on this, a phase controller 136 adapted to the whistle-type generator 12 and the resonant horn 13 will be arranged on the base 11 to synchronize and appropriately adjust the waveforms output from each sound source, thereby achieving the superposition effect of sound waves and optimizing the final cloud intervention effect and the corresponding rain enhancement operation effect. It is easy to understand that this solution does not involve any radical modification to the specific structure and operation of the whistle-type generator 12 and the resonant horn 13; therefore, their related component structures and performance can be understood by referring to conventional industry technologies, and will not be elaborated upon further in this paper.

[0060] Generally, the resonant bracket 134 is a U-shaped bracket composed of three panels on the bottom and sides, as shown in the figure, to provide sufficient adjustment space for the pitch movement of the resonant horn 13 and avoid interference or obstruction to the main structure of the resonant horn 13. Of course, in practical applications, a rod-type or box-type bracket structure can also be used as the specific structural form of the resonant bracket 134, but it is necessary to ensure that the resonant horn 13 has sufficient angle adjustment space.

[0061] In summary, the array-type acoustic rain enhancement device provided in this invention, during its operation, can flexibly move each sound-generating mechanism to an appropriate position on the top surface of the base to meet the rain enhancement needs under different working conditions. This adjusts the array layout formed by the coordinated operation of the various sound-generating mechanisms, thereby achieving the layout effect of the sound field formed by the coordinated operation of the various sound-generating mechanisms. Combined with the coordinated operation of various resonant mechanisms, the propagation direction of the sound field formed by the sound-generating mechanisms is adjusted and influenced from the outside, thereby intervening in the cloud layer corresponding to the current meteorological environment, thus meeting the rain enhancement needs under the current working conditions. When the meteorological environment changes and the cloud layer state changes accordingly, each sound-generating mechanism can be moved to a new working position to readjust the array layout of the various sound-generating mechanisms, thereby readjusting the sound field. Combined with the coordinated operation of various resonant mechanisms, the cloud layer intervention effect of the array-type acoustic rain enhancement device is adjusted accordingly to match the rain enhancement needs under the current meteorological environment. Therefore, the array-type acoustic rain enhancement device can adjust the working position of the sound-generating mechanism according to changes in meteorological environment and working conditions, thereby adjusting the corresponding sound field effect to match the cloud interference requirements under different working conditions and meet the rain enhancement operation needs under different working conditions. This significantly improves the working condition adaptability of the array-type acoustic rain enhancement device, making its operation and use more convenient and efficient.
