Detailed implementation manners

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to together Figures 1 to 4 , and now the acoustic wave fog eliminator provided by the present utility model will be described. The acoustic wave fog eliminator includes a vehicle chassis 5 and a diesel generator 10, an electrical box 12, a gas supply combination, an acoustic wave modulation generator and an acoustic wave transmission cylinder 1 arranged on the vehicle chassis 5; a cab 9 is arranged on the front side of the vehicle chassis 5, and a rotation driving mechanism is arranged on the rear side of the vehicle chassis 5. The rotation driving mechanism includes a horizontal rotation assembly for driving the acoustic wave transmission cylinder 1 to horizontally rotate around a vertical axis, a support frame 3 arranged on the horizontal rotation assembly, and an inclination angle adjustment assembly for adjusting the emission angle of the acoustic wave transmission cylinder 1; the inclination angle adjustment assembly is arranged on the support frame 3; the emission angle of the acoustic wave transmission cylinder 1 is obtained by adjusting the horizontal rotation assembly and the inclination angle adjustment assembly.

[0027] The acoustic fog elimination device provided by the utility model can drive the acoustic wave transmitting cylinder 1 to horizontally rotate 360° when the surrounding components do not block through the horizontal rotation component, so as to meet the requirement that when the vehicle is parked in one orientation, the adjustment of the emission angle in a larger range can be realized; and the inclination angle adjustment component is used to adjust the inclination angle between the acoustic wave transmitting cylinder 1 and the horizontal plane. The inclination angle adjustment component can drive the acoustic wave transmitting cylinder 1 to have an inclination angle in the range of 0-90°, including the two end point values; through the horizontal rotation component and the inclination angle adjustment component, the adjustment of the emission angle of the acoustic wave transmitting cylinder 1 in a larger range can be obtained, greatly improving the flexibility and convenience of the device. Especially for areas with limited terrain, when the vehicle is parked in one orientation, the emission angle in a larger range can be achieved, expanding the fog elimination influence area of the emission direction and coverage range, and improving the fog elimination effect.

[0028] Among them, the acoustic wave modulation generator includes an air chamber and a reverberation chamber. The reverberation chamber is connected to the air chamber, the acoustic wave transmitting cylinder 1 is connected to the reverberation chamber, and the reverberation chamber is connected to the air chamber.

[0029] The air supply combination includes a variable frequency screw air compressor 8, a purifier 7, a gas storage tank 6, and configured pressure regulating valves, flow regulating valves, pressure sensors, flow meters and solenoid valves. Starting from the variable frequency screw air compressor 8, they are sequentially connected to the purifier 7, the gas storage tank 6, the pressure regulating valve, the flow regulating valve, the pressure sensor, the flow meter and the solenoid valve to the air chamber of the acoustic wave modulation generator.

[0030] Among them, a carriage 11 or a ceiling is provided on the vehicle chassis 5 to protect the diesel generator 10, the electrical box 12, the air supply combination, the acoustic wave modulation generator and the acoustic wave transmitting cylinder 1 from wind and rain.

[0031] In some embodiments, as Figures 1 to 4 shown, the horizontal rotation component includes a first motor (not shown in the figure) provided on the vehicle chassis 5, a driving gear (not shown in the figure) connected to the main shaft of the first motor, and a turntable gear 4 rotatably installed on the vehicle chassis 5 through a first shaft (not shown in the figure). The turntable gear 4 meshes with the driving gear. The first motor is installed on the vehicle chassis 5 by bolts to provide power for the rotation of the turntable gear 4. The first motor is powered by the diesel generator 10 and the electrical box 12.

[0032] In order to avoid friction caused by the large-area contact and rotation between the turntable gear 4 and the vehicle chassis 5, therefore, a round table (not shown in the figure) protruding axially downward is provided on the lower surface of the turntable gear 4. The diameter of the round table is smaller than the outer tooth ring diameter of the turntable gear 4, and the height of the round table is less than 5 mm.

[0033] In some embodiments, as Figure 3As shown in the figure, a support base 15 is provided on the upper surface of the vehicle chassis 5. The turntable gear 4 is supported on the support base 15, and the first shaft is arranged on the support base 15; the first motor is installed on the upper surface of the vehicle chassis 5. The support base 15 includes support feet and a support circular plate arranged on the support feet. The support circular plate can be equivalent to the frustum mentioned above. The support feet are fixed to the vehicle chassis 5 by bolts. At this time, the first shaft is installed on the support circular plate. In order to realize the rotation of the turntable gear 4, there are two installation methods for the first shaft. One is that the first shaft is fixedly installed on the support circular plate, and a bearing is arranged between the turntable gear 4 and the first shaft, and the turntable gear 4 rotates with the driving gear; the other is that the first shaft is installed on the support circular plate through a bearing, and the turntable gear 4 is key-connected to the first shaft. When rotating, the first shaft and the turntable gear 4 rotate synchronously.

[0034] This installation method of arranging the support base 15 on the vehicle chassis 5 to install the rotary drive mechanism has the advantages that: it provides a larger space for adjusting the inclination angle of the acoustic wave transmitting cylinder 1 in the up and down direction, facilitates the installation of the turntable gear 4, the first motor can be installed on the upper surface of the vehicle chassis 5, the installation operation is simple and convenient, and it is also convenient for future maintenance.

[0035] In some embodiments, as Figure 4 shown, a lengthened bushing 16 extending upward is provided in the central hole of the turntable gear 4, and the first shaft passes through the central hole of the turntable gear 4 and extends into the lengthened bushing 16. By providing the lengthened bushing 16, the length of the cooperation between the turntable gear 4 and the first shaft is increased, thereby ensuring the coaxiality of the two.

[0036] In some embodiments, a bearing (not shown in the figure) is arranged between the lengthened bushing 16 and the first shaft, and the first shaft is fixed to the vehicle chassis 5. At this time, the first shaft does not rotate, and the turntable gear 4 rotates around the first shaft. An open pin or a shaft retaining ring is arranged at the upper end of the first shaft to limit the axial movement of the turntable gear 4.

[0037] In some embodiments, a bearing (not shown in the figure) is arranged between the first shaft and the vehicle chassis 5, the turntable gear 4 is key-connected to the first shaft, and a locking screw for radially locking the turntable gear 4 is arranged between the turntable gear 4 and the first shaft. In this design, the first shaft rotates with the turntable gear 4.

[0038] In some embodiments, the first motor is installed under the vehicle chassis 5, and the main shaft of the first motor passes through the vehicle chassis 5, and the driving gear is key-connected to the upper end of the main shaft of the first motor.

[0039] In some embodiments, as Figures 1 to 6As shown, a transfer sleeve 13 is sleeved on the acoustic wave transmitting cylinder 1. The first shaft is connected to the transfer sleeve 13, and a locking screw is provided between the transfer sleeve 13 and the acoustic wave transmitting cylinder 1. The first shaft drives the transfer sleeve 13 to rotate, and the transfer sleeve 13 drives the acoustic wave transmitting cylinder 1 to rotate. The first shaft can also pass through the transfer sleeve 13 and be directly fixed on the acoustic wave transmitting cylinder 1.

[0040] In some embodiments, as Figures 1 to 6 shown, the inclination angle adjusting assembly includes bearing seats 2 respectively arranged on two support frames 3, a second shaft 14 installed on the bearing seats 2, and a second motor (not shown in the figure) connected to the second shaft 14. Bearing seats 2 are provided on both support frames 3, and the acoustic wave transmitting cylinder 1 is rotatably connected to the bearing seats 2 through two second shafts 14. The second motor drives the second shaft 14 to rotate, and the second shaft 14 drives the acoustic wave transmitting cylinder 1 to lift upward to adjust the inclination angle. The second motor can drive the axis of the acoustic wave transmitting cylinder 1 to be in a horizontal state for emission, at this time the inclination angle is 0°, or in a vertical state, at this time the inclination angle is 90°.

[0041] In some embodiments, a worm and worm gear reducer is provided between the second motor and the second shaft 14. The worm and worm gear reducer has a self-locking function, which can lock the acoustic wave transmitting cylinder 1 adjusted to the emission angle to ensure the accuracy of the emission angle and the emission azimuth.

[0042] Most of the existing acoustic wave transmitting cylinders are horn-shaped, and the inlet diameter of the end of the acoustic wave transmitting cylinder connected to the acoustic wave modulation generator is much smaller than the outlet diameter of the emission end. Generally, the rotation support point for supporting the acoustic wave transmitting cylinder is located at the small-diameter end of the acoustic wave transmitting cylinder. Therefore, when the acoustic wave transmitting cylinder is adjusted to a certain inclination angle for emission, there will be a feeling of top-heavy and bottom-light. This way of supporting the acoustic wave transmitting cylinder only by the rotation support point will cause the large outlet diameter end to have a tendency to sag, resulting in inaccurate emission azimuth, affecting the affected area of the straight pipe emission gun barrel, and reducing the effect of artificial fog dissipation. Therefore, the present application adopts a technical means to solve the above problems.

[0043] As Figures 5 to 7 shown, a telescopic support 17 is provided between the turntable gear 4 and the acoustic wave transmitting cylinder 1. The telescopic support 17 includes an electric push rod. The cylinder body of the electric push rod is hinged to the turntable gear 4, and the actuating rod of the electric push rod is hinged to the lower side of the acoustic wave transmitting cylinder 1, and the hinge point with the acoustic wave transmitting cylinder 1 is located behind the support frame 3. The acoustic wave transmitting cylinder 1 has a tapered section and a flared section, and the flared section is in the shape of a bowl mouth. The telescopic support 17 is installed on the turntable gear 4 and rotates horizontally with the turntable gear 4. When the inclination angle adjusting assembly adjusts the inclination angle of the acoustic wave transmitting cylinder 1, for example, when the acoustic wave transmitting cylinder 1 tilts upward, the electric push rod elongates accordingly to support the flared section of the acoustic wave transmitting cylinder 1.

[0044] See Figure 7As shown, the telescopic support 17 can also be a sliding structure with gear-rack cooperation. Specifically, it includes a first connecting rod 171 hinged at one end to the turntable gear 4 and a second connecting rod 172 hinged at one end to the acoustic wave transmitting cylinder 1. A guiding groove for the second connecting rod 172 to slide is provided on the first connecting rod 171. A rack 173 is provided on one side of the guiding groove, and a driving gear 174 meshing with the rack 173 is provided at the end of the second connecting rod 172. When the inclination angle of the acoustic wave transmitting cylinder 1 is increased, it drives the second connecting rod 172 to slide outwards, and the total length of the support rod formed by the first connecting rod 171 and the second connecting rod 172 increases. When the inclination angle of the acoustic wave transmitting cylinder 1 is adjusted to the emission angle, due to the self-locking effect of the meshing between the driving gear 174 and the rack 173, the support rod formed by the two connecting rods forms an inclined support for the acoustic wave transmitting cylinder 1.

[0045] Among them, an anti-detachment cover for preventing the second connecting rod 172 from slipping off is provided at the end of the first connecting rod 171. The anti-detachment cover is provided with a guiding hole through which the second connecting rod 172 can extend. The diameter of the driving gear 174 is larger than the width of the second connecting rod 172, and the driving gear 174 cannot pass through the guiding hole, thus forming an anti-detachment effect on the second connecting rod 172. Of course, the driving gear 174 is rotatably connected to the end of the second connecting rod 172.

[0046] In the above embodiments, the descriptions of the respective embodiments have their own emphases. For parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
