Description

Technical Field

[0001] The present invention relates to the technical field of sonar radar, and in particular to a rotating radar device and an identification method thereof. Background Art

[0002] Sonar radar underwater target recognition is a technology that uses the principle of sound wave signals propagating in water and interacting with underwater objects to identify and locate underwater targets by analyzing echo signals. Unlike traditional radar, sonar uses sound waves rather than electromagnetic waves, which enables it to propagate more effectively in water and detect underwater targets. The basic principle of the sonar system is to transmit sound wave signals and receive echo signals reflected by the target object. The echo signal carries information such as the location, shape, and size of the target object. By analyzing and processing the echo signal, underwater targets can be identified.

[0003] With the continuous development of sonar systems, it has become common to use sonar systems to collect representative underwater samples. However, there are still some problems in the existing sonar target identification devices in the process of identifying and collecting underwater samples. The most commonly used frequency-modulated sonar can dynamically adjust the frequency within a certain range to optimize the detection performance. Low-frequency sound waves can penetrate deeper water layers, but their resolution is low and they are suitable for deep water areas. On the contrary, high-frequency sound waves can provide higher resolution, but their penetration is poor and they are only suitable for shallow water areas. Frequency-modulated sonar identifies targets at different distances by changing the frequency, but in actual applications, the interpretation of echo signals becomes very complicated. Signals of different frequencies will have a multipath effect during the propagation process, that is, the signal returns to the receiver through different paths, which makes the echo signal no longer concise and increases the complexity of data processing.

[0014] A rotary radar identification method comprises the following steps: S1: First determine the depth of different locations in the target waters. The initial position of the device is at the deep end of the waters. First, make the low-frequency sonar detector parallel to the water surface. Low-frequency sound waves are suitable for deep waters to perform preliminary identification of underwater targets. S2: The device is driven by external traction equipment to move as a whole, and gradually approaches the edge of the water area. The depth of the water area gradually becomes shallower. By switching to use high-frequency sonar detectors, medium-frequency sonar detectors or low-frequency sonar detectors, the corresponding frequencies are used for detection according to the changes in the depth of the water area. S3: When the high-frequency sonar detector is parallel to the water surface, the corresponding focal lens installed inside the fixing frame 1, when the sound waves of the high-frequency sonar detector pass through the gradient refractive index lens and are emitted into the water, the sound waves emitted by the high-frequency sonar detector are gathered.

[0015] The present invention provides a rotary radar device and an identification method thereof, and its beneficial effects include: 1. By setting up the sonar identification component, the low-frequency sonar detector can be rotated to a position parallel to the water surface, which is suitable for target identification in deeper waters. When the device moves as a whole, the motor controls the rotation to drive the rotating shaft 1, so that the high-frequency sonar detector, the medium-frequency sonar detector and the low-frequency sonar detector use sound waves of different frequencies in turn according to the different depths of the water. Different from the adjustable frequency sonar commonly used on the market, this device uses three independent sonar detectors to emit high-frequency, medium-frequency and low-frequency fixed-frequency sound waves respectively, so as to achieve the best identification effect at different water depths.

[0016] 2. By setting up a defoaming component, when the snap-in groove rotates, it drives the connecting rod to move back and forth under the turntable. When one of the snap-in plates moves relative to each other, it can synchronously drive the other snap-in plate to move toward each other, thereby driving the two extrusion plates to squeeze the storage bag inside the floating box. During the extrusion process, the defoaming agent inside the storage bag can be sprayed through the discharge pipe to the area provided by the isolation mesh cover, thereby eliminating the bubbles in the area provided by the isolation mesh cover, that is, eliminating the bubbles in the sound wave transmission area, thereby further improving the efficiency of sending and receiving sound waves.

[0017] 3. By setting up the acoustic wave focusing component, when the floating box is placed in the water, the fixed ring can move downward under the action of the counterweight, so that the isolation net is fully deployed, thereby realizing the enclosure of the acoustic wave detection area, further converging the acoustic waves to prevent the sound waves from diffusing, and preventing other debris in the water from blocking and driving away the acoustic waves during the movement of the floating box, and preventing other debris from passing under the acoustic wave transmission, which can make it easier to detect underwater debris and identify the target object.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0022] Reference Figure 1-Figure 9 The present invention provides a technical solution: a rotary radar device, comprising a floating box 1, a floating ring 4 is fixedly installed on the bottom surface of the floating box 1, an equipment box 2 is fixedly installed on the top surface of the floating ring 4, an equipment box 2 3 is fixedly installed on the top surface of the equipment box 2, a cavity 13 is opened inside the floating box 1, two equipment cavities 10 are opened on the top surface of the floating box 1, a square through hole 11 is opened through the middle of the floating box 1, a sonar identification component 7 is arranged inside the equipment box 2, and an acoustic wave focusing component 12 is arranged on the bottom surface of the floating box 1; The sonar identification component 7 includes a rotating shaft 701, which is rotatably mounted inside the equipment box 2. A mounting frame 702 is fixedly mounted on the outer surface of the sonar identification component 7. Three mounting blocks 703 are fixedly mounted inside the mounting frame 702. The three mounting blocks 703 are equidistantly mounted. A high-frequency sonar detector 704, a medium-frequency sonar detector 705, and a low-frequency sonar detector 706 are respectively mounted on one side of the three mounting blocks 703. The high-frequency sonar detector 704, the medium-frequency sonar detector 705, and the low-frequency sonar detector 706 are configured to generate sound waves to detect and identify underwater objects. A motor 5 is arranged inside the equipment box 2 3 and is fixedly mounted on the top surface of the equipment box 1 2 . A driving wheel 6 is fixedly mounted on the output end of the motor 5 . A driven wheel 712 is fixedly mounted on the outer surface of the rotating shaft 1 701 . The driven wheel 712 and the driving wheel 6 are meshed with each other.

[0023] When performing underwater target identification and sampling, the device is first placed on the water surface, and the sonar frequency to be used is determined according to the depth of the water area. That is, before detecting the target water area, the depth of each position of the target water area should be first understood, and then the sonar radar detector of which frequency to use at different positions is determined according to the water depth. If the initial position of the device is located in the deeper water area, the driving wheel 6 is driven to engage with the driven wheel 712 by controlling the motor 5 to rotate, thereby driving the rotating shaft 701 to rotate, so that the mounting frame 702 starts to rotate until the low-frequency sonar detector 706 is parallel to the water surface. Low-frequency sound waves are suitable for deeper water areas, and thus can be used for preliminary identification of underwater targets. The traction of an external traction ship or other traction equipment can drive the device as a whole to move. As the device moves, the system will gradually approach the edge of the water area, and the depth of the water area will gradually become shallower. At this time, the motor 5 is controlled to continue to rotate, driving the rotating shaft 701 to rotate, and then switching to use the high-frequency sonar detector 704, the medium-frequency sonar detector 705 or the low-frequency sonar detector 706. These independent detectors can use corresponding frequencies for detection according to the changes in water depth, without relying on the existing adjustable frequency sonar system. In this way, the system can use sound waves of different frequencies for waters of different depths to achieve accurate target identification for depth changes. In this way, the multipath effect of signals of different frequencies during propagation can be avoided (the existing adjustable frequency sonar system signals return to the receiver through different paths, making the echo signal no longer concise and increasing the complexity of subsequent data processing), thereby avoiding the complexity of the echo signal, reducing the difficulty of data processing, and improving recognition efficiency and accuracy.

[0024] The inner walls of both sides of the square through hole 11 are rotatably mounted with mounting shafts 707, a fixing frame 708 is fixedly mounted between the two mounting shafts 707, and three focal lenses 709 are equidistantly mounted inside the fixing frame 708, which are a gradient refractive index lens, a spherical lens and a circular lens respectively.

[0025] During operation, when the mounting block 703 rotates, the driven wheel 2 713 and the driven wheel 1 712 drive the mounting shaft 707 and the fixing frame 1 708 to rotate synchronously. When the high-frequency sonar detector 704 is parallel to the water surface, the corresponding focal length lens 709 installed inside the fixing frame 1 708, that is, the gradient refractive index lens is parallel to the high-frequency sonar detector 704. When the sound waves of the high-frequency sonar detector 704 pass through the gradient refractive index lens and are emitted into the water, the sound waves emitted by the high-frequency sonar detector 704 can be effectively gathered, so that the high-frequency sonar detector 704 can enter the water in a more concentrated manner, so that When the sound waves detect an object properly, clearer data can be formed, thereby helping to identify underwater targets. Similarly, when the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 are rotated to a position parallel to the water surface, the spherical mirror and the circular lens can be located below the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 respectively, and the sound waves emitted by the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 are gathered, thereby achieving the purpose of being able to gather sound waves of different frequencies, making the detected target clearer, and avoiding the problem of existing sound waves being dispersed when transmitted into the water, resulting in unclear subsequent images.

[0026] Reference Figure 8 and Fig. 9 The acoustic wave focusing assembly 12 includes a floating plate 1203 and a fixed ring 1204, an isolation net 1205 is installed between the floating plate 1203 and the fixed ring 1204, and the acoustic wave focusing assembly 12 is set to gather and collect sound waves emitted by the high-frequency sonar detector 704, the medium-frequency sonar detector 705 and the low-frequency sonar detector 706. The bottom surface of the floating box 1 is provided with a circular groove 1201, and an electromagnet 1202 is fixedly installed inside the circular groove 1201. An adsorption plate 1207 is fixedly installed on the top surface of the floating plate 1203, and the adsorption plate 1207 is adsorbed on the bottom surface of the electromagnet 1202 and inserted into the inside of the circular groove 1201. A counterweight block 1206 is fixedly installed on the bottom surface of the fixed ring 1204.

[0027] During operation, when the floating box 1 is placed in the water, the fixing ring 1204 can move downward under the action of the counterweight block 1206, so that the isolation net 1205 is fully deployed, thereby realizing the enclosure of the sound wave detection area, and further converging the sound waves to prevent the sound waves from diffusing. In addition, during the movement of the floating box 1, other debris in the water can be prevented from blocking and driving away, and other debris can be prevented from passing under the sound wave transmission, which can make it easier to detect underwater debris and identify the target object.

[0028] After the required target object is detected, the electromagnet 1202 can be controlled to be powered off. When the electromagnet 1202 is powered off, the float plate 1203 can lose its limit, that is, the fixed ring 1204 can move toward the bottom of the water under the action of the counterweight block 1206, and the float plate 1203 can keep the isolation net 1205 in an open state under the buoyancy until the fixed ring 1204 covers the target object therein. The detected target object can be marked, and the position of the target object can be easily identified in the subsequent sampling process, which is convenient for subsequent sampling operations.

[0029] A plug-in board 902 is fixedly mounted on one side surface of the floating block 901 , and one end of the plug-in board 902 extends to the bottom of the fixing ring 1204 .

[0030] During operation, when the inclined rod 904 moves toward each other during the movement of the clamping plate 1 805, it can drive the clamping plate 2 906 to move toward the edge of the floating box 1 inside the fixing frame 2 905, thereby driving the plug-in plate 902 away from the bottom of the fixing ring 1204, so as to automatically release the electromagnet 1202.

[0031] Reference Figure 5-Figure 8 A defoaming component 8 is provided inside the floating box 1, and the defoaming component 8 includes a storage capsule 801. Extrusion plates 802 are provided on both sides of the storage capsule 801. The extrusion plates 802 are movably connected to the inside of the floating box 1. The inner walls on both sides of the equipment cavity 10 are provided with clamping grooves 804. The inside of the clamping grooves 804 is movably connected with a clamping plate 805. Both ends of the clamping plate 805 extend to the extrusion plate 802. A connecting column 803 is fixedly connected between one end of the clamping plate 805 located at the extrusion plate 802 and the extrusion plate 802. A mounting plate 806 is fixedly installed on the surface of one side of the clamping plate 805 located inside the equipment cavity 10. A spring 807 is fixedly connected between one side surface of the mounting plate 806 and one side inner wall of the equipment cavity 10. The other side surface of the clamping plate 805 is fixedly connected to a limited A mounting bracket 809 is fixedly installed on one side surface of the equipment cavity 10, a connecting rod 815 is fixedly connected to one side surface of the clamping plate 805, a rotating shaft 810 is rotatably installed inside the mounting bracket 809, a bevel gear 811 is fixedly installed on the top of the rotating shaft 810, a bevel gear 808 is fixedly installed on the outer surface of the rotating shaft 701, and the bevel gear 808 and the bevel gear 811 are meshed with each other, a turntable 812 is fixedly installed on the bottom surface of the rotating shaft 810, a boss 813 is fixedly installed on the bottom surface of the turntable 812, a limiting bracket 814 is fixedly installed on the other end of the connecting rod 815, and the boss 813 is movably clamped in the inside of the limiting bracket 814, a discharge pipe 816 is fixedly installed on the bottom surface of the floating box 1, and a pressure valve 817 is fixedly installed on the outer surface of the discharge pipe 816.

[0032] During operation, when the rotating shaft 701 rotates, that is, when switching sonars of different frequencies, the card slot 804 can be driven to rotate synchronously. When the card slot 804 rotates, the bevel gear 2 811 meshing with it can be driven to rotate, thereby driving the turntable 812 to rotate. When the turntable 812 rotates, the connecting rod 1 815 can be driven to move back and forth under the turntable 812 under the action of the limit frame 814, thereby driving the card plate 1 805 to move back and forth inside the card slot 804. Since there are two card plates 1 805, and the two card plates 1 805 are connected by the inclined rod 904 and the vertical rod 904, the card plate 1 805 can move back and forth inside the card slot 804. The rod 903 is connected to the support 907, so when one of the clamping plates 805 moves relative to each other, it can synchronously drive the other clamping plate 805 to move toward each other, thereby driving the two extrusion plates 802 to squeeze the storage capsule 801 inside the floating box 1. During the extrusion process, the defoaming agent inside the storage capsule 801 can be sprayed through the discharge pipe 816 to the area covered by the isolation net 1205, thereby eliminating the bubbles in the area covered by the isolation net 1205, that is, eliminating the bubbles in the sound wave transmission area, thereby further improving the efficiency of sending and receiving sound waves, and then being able to improve the quality of subsequent imaging.

[0033] Furthermore, in the above, the defoaming agent can be sprayed every time the sound wave frequency is changed, thereby improving the quality of defoaming and avoiding the generation of bubbles.

[0034] Reference Figure 5 and Figure 8 A balancing assembly 9 is provided on the top surface of the floating box 1, and the balancing assembly 9 includes four vertical poles 903, and the four vertical poles 903 are symmetrically installed in pairs on the top surface of the clamping plate 805. The top of the vertical poles 903 is rotatably installed with an inclined rod 904, and one end of the inclined rod 904 is movably connected to the inside of the support 907. A fixing frame 905 is fixedly installed on the top surface of the floating box 1, and a clamping plate 906 is movably clamped inside the fixing frame 905.

A connecting plate 909 is fixedly installed on one end of the connecting rod 908, and a floating block 901 is fixedly installed on the bottom surface of the connecting plate 909.

[0035] During operation, in actual use, when the inclined rod 904 moves toward each other during the movement of the clamping plate 805, it can drive the clamping plate 906 to move inside the fixed frame 905 toward the edge of the floating box 1, thereby increasing the extension distance of the floating block 901, that is, when changing the sound waves of different frequencies, the floating block 901 can cover a larger area, ensuring that when changing the sound waves of different frequencies, the stability of the floating box 1 can be guaranteed, and the bottom surface of the floating block 901 is parallel to the bottom surface of the floating ring 4, that is, when the floating box 1 is placed on the water surface, it can provide auxiliary support for the floating box 1, and when the driving wheel 6 is started, it can extend outward, so that the coverage area of ​​the floating block 901 is wider, thereby obtaining a better support effect, so that when the driving wheel 6 is started, the floating stability of the floating box 1 is guaranteed.

[0036] A rotary radar identification method comprises the following steps: S1: First, determine the depth of different positions of the target water area. If the initial position of the device is at a deep water area, first make the low-frequency sonar detector 706 parallel to the water surface. The low-frequency sound wave is suitable for deep water areas, and the underwater target is preliminarily identified; S2: The device can be moved as a whole by being towed by an external towing ship or other towing equipment. The system will gradually approach the edge of the water area, and the depth of the water area will gradually become shallower. By switching to use the high-frequency sonar detector 704, the medium-frequency sonar detector 705 or the low-frequency sonar detector 706, the corresponding frequencies can be used for detection according to the change in the depth of the water area; S3: When the high-frequency sonar detector 704 is parallel to the water surface, the corresponding focal lens 709 installed inside the fixing frame 1 708, that is, the gradient refractive index lens is parallel to the high-frequency sonar detector 704. When the sound waves of the high-frequency sonar detector 704 pass through the gradient refractive index lens and are emitted into the water, the sound waves emitted by the high-frequency sonar detector 704 are gathered. Similarly, during the use of the medium-frequency sonar detector 705 and the low-frequency sonar detector 706, there will also be corresponding focal lenses 709 to gather the sound waves. S4: By controlling the electromagnet 1202 to be powered off, the floating disc 1203 can lose its limit, that is, the fixing ring 1204 moves toward the bottom of the water, and the floating disc 1203 can keep the isolation net 1205 in an open state under the buoyancy, and the target object can be covered therein, so that the detected target object can be marked, which is convenient for subsequent sampling operations; S5: When switching sonars of different frequencies, the two squeezing plates 802 squeeze the storage capsule 801 inside the floating box 1, and the defoaming agent inside the storage capsule 801 is sprayed to the area covered by the isolation net 1205 through the discharge pipe 816, thereby eliminating the bubbles in the area covered by the isolation net 1205.

[0037] Specifically, the working process or working principle of the rotary radar device and its identification method is as follows: when in use, in the process of identifying and sampling the required underwater objects, firstly, the device as a whole only needs to be placed on the water surface, and the sonar frequency to be used first is determined according to the depth of the identified water area. If the initial position is in the center of the water area, the motor 5 can be controlled to rotate. When the motor 5 rotates, the driving wheel 6 can drive the driven wheel 712 meshing with it to rotate, thereby driving the rotating shaft 701 to rotate, and then the mounting frame 702 is rotated until the low-frequency sonar detector 706 rotates to a position parallel to the water surface. Since short-frequency sound waves are suitable for deeper waters, Then the underwater target can be identified. As the device moves as a whole, it will move towards the center of the water area towards the edge. That is, as the device moves as a whole, the depth of the identified water area will become shallower and shallower. At this time, the motor 5 can be controlled to rotate to drive the rotating shaft 1 701 to rotate, so that the high-frequency sonar detector 704, the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 can use sonar waves of different frequencies when facing waters of different depths. The high-frequency sonar detector 704, the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 are used to replace the existing adjustable frequency sonar, thereby achieving the purpose of enabling the identification of different depths to be returned separately accordingly.

[0038] When the mounting block 703 rotates, the driven wheel 2 713 and the driven wheel 1 712 drive the mounting shaft 707 and the fixing frame 1 708 to rotate synchronously. When the high-frequency sonar detector 704 is parallel to the water surface, the corresponding focal lens 709 installed inside the fixing frame 1 708, that is, the gradient refractive index lens is parallel to the high-frequency sonar detector 704. When the sound waves of the high-frequency sonar detector 704 pass through the gradient refractive index lens and are emitted into the water, the sound waves emitted by the high-frequency sonar detector 704 can be effectively gathered, so that the high-frequency sonar detector 704 can enter the water in a more concentrated manner, so that when the sound waves detect an object, clearer data can be formed, thereby helping to identify underwater targets. Similarly, when the intermediate-frequency sonar detector 705 and the low-frequency sonar detector 706 rotate to a position parallel to the water surface, The spherical mirror and the circular lens can be respectively located below the medium-frequency sonar detector 705 and the low-frequency sonar detector 706, and the sound waves emitted by the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 can be gathered, thereby achieving the purpose of being able to gather sound waves of different frequencies, making the detected target object clearer. When the floating box 1 is placed in the water, the fixing ring 1204 can move downward under the action of the counterweight block 1206, so that the isolation net 1205 is fully deployed to achieve the enclosure of the sound wave detection area, and the sound waves can be further gathered to prevent the sound waves from diffusing. In addition, during the movement of the floating box 1, it can prevent interference from other debris in the water, and can block and drive away other debris to prevent other debris from passing under the sound wave transmission, which can be more convenient for detecting underwater debris and determining the target object.

[0039] It should be noted that the high-frequency sonar detector 704, the medium-frequency sonar detector 705 and the low-frequency sonar detector 706 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
