Description

Technical Field

[0001] The present invention relates to the technical field of acoustic repelling devices, and particularly to a waveguide beam-controlled high sound pressure level acoustic repelling device and system. Background Art

[0002] The waveguide beam-controlled high sound pressure level acoustic repelling device is a long-distance acoustic device. The principle is to use a high sound pressure level transducer array. According to the strongly directional propagation mode of sound waves, by playing strong high sound pressure level sound waves within a certain coverage angle, it is widely used in areas such as airports, reservoirs, and mining areas.

[0003] Most of the currently common waveguide beam-controlled high sound pressure level acoustic repelling devices on the market are similar in overall structure. The emission direction is adjusted by driving a frame to swing through a built-in brushless motor. The built-in high sound pressure level transducer array can emit high sound pressure level sound waves directionally. There are some functional deficiencies in the actual use process and there is room for improvement. For example, most of the current waveguide beam-controlled high sound pressure level acoustic repelling devices collect image information through a camera to control the motor to drive the device to adjust the direction. As an information collection component, the camera is easily covered by dust in the outdoor environment for a long time and needs to be wiped and cleaned regularly, which is rather troublesome and does not have the function of lens cleaning and dust prevention.

[0004] Now, a new type of waveguide beam-controlled high sound pressure level acoustic repelling device and system are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a waveguide beam-controlled high sound pressure level acoustic repelling device and system to solve the problem of not having the function of lens cleaning and dust prevention proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A waveguide beam-controlled high sound pressure level acoustic repelling device, including a bottom fixed seat. The front end of the bottom fixed seat is fixedly connected with a controller. The top end of the bottom fixed seat is fixedly connected with a bottom housing. At the top end inside the bottom housing, a first brushless reduction motor is installed. The top end of the bottom housing is movably connected with a top housing. The outside of the top housing is movably connected with a concave support frame. On the left and right sides of the concave support frame, array protection shells are respectively fixedly connected. Inside the array protection shells, multiple groups of high sound pressure level acoustic array units are installed. The front end of the array protection shell is fixedly connected with a metal protection net. The top end of the concave support frame is fixedly connected with a top cover shell. At the middle position of the front end of the top cover shell, a camera module is installed. On both sides inside the top housing, second brushless reduction motors are respectively installed. At the bottom end of the top cover shell, a dust-proof component that can prevent the lens from being covered with dust is provided.

[0007] The dust-proof component includes an air collecting cavity, which is fixedly connected to the bottom end of the top housing. A negative pressure fan is installed at the bottom end of the air collecting cavity. The front end of the air collecting cavity is fixedly connected to a flat air outlet pipe, and the bottom end of the flat air outlet pipe is fixedly connected to an air spraying nozzle.

[0008] As a further technical solution of the present invention, the negative pressure fan penetrates through the bottom end of the air collecting cavity, and the interior of the air collecting cavity and the negative pressure fan are connected and communicated.

[0009] As a further technical solution of the present invention, the interiors of the air collecting cavity, the flat air outlet pipe, and the air spraying nozzle are connected and communicated, and the rear end of the air spraying nozzle is in contact with the front end of the top housing.

[0010] As a further technical solution of the present invention, the front ends of the top housing and the camera module are flush, and the controller is electrically connected to the negative pressure fan.

[0011] As a further technical solution of the present invention, a sensor housing is fixedly connected to the front end of the top housing. A human body sensor is fixedly connected to the bottom at the middle position of the front end of the sensor housing. A proximity sensor is arranged above the human body sensor, and speakers are respectively fixedly connected to both sides of the front end of the sensor housing.

[0012] As a further technical solution of the present invention, the speakers are symmetrically distributed about the vertical center line of the sensor housing, and the controller is electrically connected to the human body sensor, the proximity sensor, and the speakers.

[0013] As a further technical solution of the present invention, an internally threaded fixing ring is welded at the middle position of the bottom end of the array protective housing. A placement cavity is arranged below the internally threaded fixing ring. A positioning ring is welded at the top of the outside of the placement cavity, and an externally threaded ring is fixedly connected to the top of the placement cavity.

[0014] As a further technical solution of the present invention, an insect repellent agent block is horizontally placed inside the placement cavity.

[0015] As a further technical solution of the present invention, the threads on the outside of the externally threaded ring match the threads inside the internally threaded fixing ring, and the interiors of the array protective housing and the placement cavity are connected and communicated.

[0016] The waveguide beam-controlled high sound pressure level sound wave repelling system includes the following steps:

[0017] S1: The first brushless reduction motor controls the horizontal swing of the top housing, the second brushless reduction motor adjusts the pitch angle of the concave support frame, and the direction of the high sound pressure level sound waves emitted by the high sound pressure level sound wave array unit inside the array protective housing can be changed, and the camera module collects image information of the monitoring area;

[0018] S2: The negative pressure fan at the top of the air collecting cavity continuously blows air into it, increasing the air pressure inside the air collecting cavity. The air flow continuously blows air against the surface of the camera module along the flat air outlet pipe and the air spraying nozzle, forming an air curtain on its surface, which can blow away rainwater even in rainy weather.

[0019] S3: When someone is in the direct front, the human body sensor and the proximity sensor on the sensor housing can capture the human body signal in real time, and the speaker broadcasts the voice for driving away.

[0020] S4: The surface of the metal protective net has fine holes. The smell emitted by the insect repellent agent block in the placement cavity can escape partially through the holes in the metal protective net, preventing small mosquitoes from drilling into the device and breeding inside. The placement cavity together with the external thread ring can be directly unscrewed from the internal thread fixing ring to replace the insect repellent agent block inside.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The waveguide beam-controlled high sound pressure level sound wave driving-away device not only realizes the function of lens cleaning and preventing dust accumulation, but also realizes the function of safety reminder for approaching personnel, and also realizes the function of preventing insects inside.

The camera module collects the image information of the monitoring area. During the operation of the device, the negative pressure fan at the top of the air collecting cavity continuously blows air into it, increasing the air pressure inside the air collecting cavity. The air flow continuously blows air against the surface of the camera module along the flat air outlet pipe and the air spraying nozzle, forming an air curtain on its surface to prevent dust from covering, and can also blow away rainwater in rainy weather, realizing the function of lens cleaning and preventing dust accumulation.
