Description

Technical Field

[0001] The present invention relates to the technical field of acoustic signal transmission, and in particular to an acoustic signal transmission device in a rotating state. Background Art

[0002] The transmission device in the rotating state usually has a mechanical rotating device to drive the transducer to rotate. The transducer is the core component of the sonar system. It can convert electrical signals into sound signals and transmit them, and can also convert received sound signals into electrical signals. For example, a Chinese patent with publication number CN219349137U is a mechanical scanning sonar; During the operation of the transmission device in a rotating state, the transducer located in its inner cavity will rotate. This rotation action drives the rotor in the inner cavity of the slip ring to rotate synchronously. The receiving end of the transducer is closely attached to the conductive ring. When the transducer receives the external acoustic signal, it will convert it into an electrical signal and conduct it through the conductive ring connected to the receiving end. At this time, the brush installed on the surface of the slip ring stator is in close contact with the rotating conductive ring. As the conductive ring rotates, the brush can receive the electrical signal transmitted by the conductive ring in real time. As the key node of signal transmission, the brush stably transmits the received signal to the acoustic electronic system for subsequent signal processing, analysis, and extraction of target information, thereby realizing the effective detection and information collection of the surrounding environment by the scanning sonar in a rotating state.

[0003] However, since the brush and the conductive ring are rotatably connected, when the transmission device is used on a ship, the continuous operation of the ship's engine and the impact of the waves will cause the entire equipment to vibrate frequently and irregularly. This vibration is transmitted to the brush and the conductive ring, which may cause the brush to momentarily shift or jump on the surface of the conductive ring, thereby destroying the originally tight fit between the two, and ultimately causing interruptions in the signal during transmission. Summary of the invention

[0004] The object of the present invention is to provide an acoustic signal transmission device in a rotating state to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0017] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0018] See also Figure 1-Figure 9 As shown, this embodiment provides an acoustic signal transmission device in a rotating state, including a transmission frame body 100, a support plate 110 is fixedly connected to the inner wall of the transmission frame body 100, a partition 120 is fixedly connected below the support plate 110 in the inner cavity of the transmission frame body 100, and an acoustic signal component 200 is arranged at the bottom of the partition 120.

[0019] A support assembly 300 is disposed at the bottom of the inner cavity of the transmission frame body 100 . A transmitting and receiving assembly 400 is disposed in the inner cavity of the support assembly 300 . The transmitting and receiving assembly 400 is used to receive and convert electrical signals and acoustic signals.

[0020] The inner cavity of the support component 300 is provided with a connection component 500, and the surface of the connection component 500 is in contact with the transmitting and receiving component 400 for transmitting the signal of the receiving component 400, and the setting of the connection component 500 can always maintain a close fit with the transmitting and receiving component 400.

[0021] The receiving component 400 first converts electrical energy into sound energy and emits ultrasonic pulses underwater. When these ultrasonic waves encounter underwater targets such as submarines, sunken ships, schools of fish, etc., reflected waves are generated. After the reflected waves are returned and received by the receiving component 400, the receiving component 400 converts the sound energy into electrical energy and transmits it to the acoustic signal component 200. At this time, the acoustic signal component 200 can determine the existence, distance and direction of the target by analyzing the echo signal.

[0022] Since the transmitting and receiving component 400 can only detect targets within a certain angle range in front of it, it is necessary to rotate the transmitting and receiving component 400 to change the emission and reception direction of the ultrasonic wave, thereby realizing scanning over a larger range. The acoustic signal component 200 uses wires when receiving the transmitting and receiving component 400. At this time, the rotation of the transmitting and receiving component 400 will cause the wires to be entangled. By setting the connecting component 500, the electrical connection between the acoustic signal component 200 and the transmitting and receiving component 400 can be maintained during the rotation of the transmitting and receiving component 400.

[0023] At the same time, the setting of the connecting component 500 can ensure that there is sufficient pressure when the connecting component 500 is connected to the transmitting and receiving component 400, so that the connecting component 500 always fits the transmitting and receiving component 400, and prevents insufficient contact pressure. During the rotation of the transmitting and receiving component 400, due to the influence of centrifugal force, vibration and other factors, the connecting component 500 may gradually lose contact with the transmitting and receiving component 400, thereby causing interruptions in the signal during transmission.

[0024] On the basis of the above, the specific structure is disclosed in detail: In order to enable the support assembly 300 to fix the transmitting and receiving assembly 400, the parts of the support assembly 300 need to be disclosed. Therefore, the support assembly 300 includes a slip ring 310 fixedly connected to the bottom of the inner cavity of the transmission frame body 100, and the slip ring 310 includes a stator 3101 and a rotor 3102.

[0025] The stator 3101 is fixedly connected to the inner wall of the slip ring 310, and the inner wall of the stator 3101 is rotatably connected to the rotor 3102. The rotor 3102 can be rotated by rotating the transmitting and receiving assembly 400. At this time, the rotor 3102 is rotatably connected to the stator 3101, and the stator 3101 supports the rotor 3102, thereby providing a stable mechanical structure for the rotation of the transmitting and receiving assembly 400.

[0026] In order to make the transmitting and receiving component 400 detectable, it is necessary to further disclose the parts of the transmitting and receiving component 400. Therefore, the transmitting and receiving component 400 includes a transducer 410 fixedly connected to the inner wall of the rotor 3102, a transducer output terminal 450 is fixedly connected to the bottom of the transducer 410, and the top of the transducer 410 contacts a conductive ring 420.

[0027] The bottom of the conductive ring 420 is fixedly connected to the top of the rotor 3102. Through the operation of the transducer 410, the electrical signal can be converted into an acoustic signal for transmission, and then the acoustic signal is received and converted into an electrical signal, which is transmitted to the conductive ring 420 through the transducer 410, and the conductive ring 420 transmits the electrical signal to the connecting component 500, and the connecting component 500 transmits the electrical signal to the acoustic signal component 200. Through this conversion, sound waves can be used to transmit information in an underwater environment.

[0028] Considering that the transducer 410 can only detect targets within a certain angle range in front of it, if the detection range needs to be expanded, the transducer 410 needs to be rotated. Therefore, a rotating shaft 440 is fixedly connected to the top of the transducer 410, and a driving motor 430 is fixedly connected to the top of the rotating shaft 440.

[0029] A slot is provided at the top of the conductive ring 420 for cooperating with the rotation of the rotating shaft 440; the bottom of the driving motor 430 is fixedly connected to the surface of the support plate 110, and the operation of the driving motor 430 can drive the rotating shaft 440 to rotate, and the rotation of the rotating shaft 440 can drive the transducer 410 to rotate, and the rotation of the transducer 410 can expand the transmission range and the receiving range.

[0030] In order to enable the connecting component 500 to contact with the transmitting and receiving component 400, so as to transmit the signal of the transmitting and receiving component 400, a groove 31010 is opened on the inner wall of the stator 3101, and the connecting component 500 is arranged on the inner wall of the groove 31010. By opening the groove 31010 on the inner wall of the stator 3101 and fixing the connecting component 500 on the inner wall, it can contact with the transmitting and receiving component 400 and transmit the signal.

[0031] In order to enable the connection component 500 to transmit signals, it is necessary to further disclose the parts of the connection component 500. Therefore, the connection component 500 includes a brush 540 that is in contact with and connected to the inner wall of the groove 31010. The surface of the brush 540 is rotatably connected to the surface of the conductive ring 420. By arranging the brush 540 on the inner wall of the groove 31010 and surrounding the surface of the conductive ring 420, the conductive ring 420 can be rotatably connected to the brush 540 when the conductive ring 420 rotates, and the signal can be transmitted through the brush 540. Due to the setting of the groove 31010, the upper and lower ends of the brush 540 can be tightly fitted with the inner wall thereof, thereby limiting the position of the brush 540 and preventing the brush 540 from moving due to other factors such as vibration.

[0032] In order to keep the brush 540 and the conductive ring 420 in close contact at all times, it is necessary to apply pressure to the brush 540. Therefore, a plurality of fixtures 550 are fixedly connected to the inner wall of the groove 31010, a connecting ring 510 is fixedly connected to the inner wall of the fixture 550, a plurality of connectors 520 are fixedly connected to the inner wall of the connecting ring 510, and a spring 530 is fixedly connected to the inner wall of the connector 520. One end of the spring 530 away from the connector 520 is fixedly connected to the surface of the brush 540. By fixing a plurality of fixers 550 to the inner wall of the groove 31010, the connecting ring 510 and the connector 520 can be fixed to the inner wall of the groove 31010 at the same time, and the end of the spring 530 in the inner cavity of the connector 520 is connected to the surface of the brush 540. At this time, the brush 540 will surround the surface of the conductive ring 420, and due to the elastic characteristics of the spring 530, it can continuously apply force to the brush 540, thereby ensuring that the brush 540 is always tightly attached to the surface of the conductive ring 420 under any circumstances, effectively avoiding poor contact problems caused by various factors such as vibration, rotation, etc.

[0033] In order to enable the acoustic signal component 200 to transmit the signal in the brush 540 that has received the signal from the transducer 410, it is necessary to further disclose the parts of the acoustic signal component 200. Therefore, the acoustic signal component 200 includes an acoustic signal device 210 fixedly connected to the bottom of the partition 120. Two connectors 220 are fixedly connected to the output end of the acoustic signal device 210. The inner wall of the connector 220 is fixedly connected to a wire 230. The end of the wire 230 is fixedly connected to the surface of the spring 530. The signal can be transmitted to the conductive ring 420 through the operation of the transducer 410. Due to the contact between the conductive ring 420 and the brush 540, the brush 540 can receive the signal of the conductive ring 420, and then the wire 230 in contact with the brush 540 transmits the signal to the acoustic signal device 210 for analysis.

[0034] Working principle: The driving motor 430 can drive the shaft 440 to rotate, and the rotation of the shaft 440 can drive the transducer 410 to rotate. At this time, the rotation of the transducer 410 can expand the range of transmission and the range of reception. The transducer 410 can convert the electrical signal into an acoustic signal for transmission, and then receive the acoustic signal and convert it into an electrical signal, and transmit it to the conductive ring 420 attached thereto through the transducer 410. Since the surface of the transducer 410 is fixedly connected to the rotor 3102, the rotor 3102 will rotate with the rotation of the transducer 410, and at the same time, the top of the rotor 3102 The conductive ring 420 rotates accordingly to maintain contact with the transducer 410, thereby receiving the signal from the transducer 410. The rotation of the conductive ring 420 can make it rotatably connected to the brush 540. By providing a plurality of springs 530 on the outer surface of the brush 540, a force can be continuously applied to the brush 540, thereby ensuring that the brush 540 always closely contacts the surface of the conductive ring 420 under any circumstances. Then, the brush 540 is fixedly connected to the wire 230, and the signal received by the brush 540 is transmitted to the acoustic signal device 210 through the wire 230, and the acoustic signal device 210 performs data analysis and converts the image.
