A side-scan sonar device

Abstract

This invention provides a side-scan sonar device, including a protective shell, a lifting plate, a first electric telescopic rod, a winding device, a side-scan sonar, a fixing clamp, a baffle, and a second electric telescopic rod. The protective shell protects the side-scan sonar, and when the sonar is stored inside the protective shell, it is fixed below the lifting plate by the fixing clamp, preventing movement and avoiding the risk of damage due to accidental contact during transport. When measuring in complex areas with significant underwater topographic variations, the lifting plate can be extended beyond the protective shell by the first electric telescopic rod to conduct measurements, preventing environmental damage to the side-scan sonar during use. For areas suitable for towed measurement, the fixing clamp can be released, and the winding device can be released to lower the side-scan sonar into the water for measurement.

Description

Technical Field

[0001] This utility model relates to the field of marine exploration technology, and in particular to a side-scan sonar device. Background Technology

[0002] With the large-scale development of my country's marine resources, the implementation of major marine surveys, and the increase in various marine engineering projects, sonar devices have been widely purchased and applied by numerous domestic management departments, research institutes, universities, the navy, surveying and mapping institutes, and large and medium-sized marine enterprises from abroad. Existing marine surveying sonar devices have poor protective capabilities, making it inconvenient to store and protect them after use, thus posing a high risk of damage due to accidental impact during transport. Furthermore, while side-scan sonar measurements are generally towed, in complex areas with significant underwater topographic variations, hull-mounted measurements are used. Combining these two methods would significantly expand the application range of sonar devices. Utility Model Content

[0003] In view of this, the present invention aims to provide a side-scan sonar device to solve the above problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A side-scan sonar device includes a protective shell, a lifting plate, a first electric telescopic rod, a winding device, a side-scan sonar, a fixing clamp, a baffle, and a second electric telescopic rod.

[0006] The protective shell is fixed to the side wall of the hull. The lower end of the protective shell is open and hinged with a baffle. The baffle is connected to the side wall of the protective shell through a second electric telescopic rod. Inside the protective shell, there is a horizontally set lifting plate. The lifting plate is connected to the top of the protective shell through a first electric telescopic rod. A winding device is set in the middle of the upper surface of the lifting plate. The winding device is driven by a first motor. A pull rope is wound on the winding device. The lifting plate has a through hole for the pull rope to pass through. A side-scan sonar is set below the lifting plate. The pull rope passes through the through hole and is connected to the lifting ring on the side-scan sonar. A fixing clamp for clamping the side-scan sonar is also set below the lifting plate. The fixing clamp includes a clamping arm, a driven wheel, a driving wheel, a second motor, and a mounting bracket. There are two clamping arms. The upper end of the clamping arm is fixedly connected to the driven wheel. The driven wheel is rotatably mounted on the mounting bracket, and the two driven wheels mesh with each other. A driving wheel is also set on the mounting bracket. The driving wheel meshes with one of the driven wheels. The driving wheel is driven by a second motor. The mounting bracket is fixed to the lower surface of the lifting plate.

[0007] Furthermore, the protective shell is rectangular in shape, and the baffle is hinged to the long side of the bottom of the protective shell.

[0008] Furthermore, there are two baffles, and the two baffles are in a split-opening mode.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-2 As shown, a side-scan sonar device includes a protective shell 1, a lifting plate 2, a first electric telescopic rod 3, a winding device 4, a side-scan sonar 9, a fixing clamp 11, a baffle 17, and a second electric telescopic rod 18.

[0027] The protective shell 1 is fixed to the side wall of the hull. The lower end of the protective shell 1 is open and hinged with a baffle 17. The baffle 17 is connected to the side wall of the protective shell 1 via a second electric telescopic rod 18. Inside the protective shell 1, a horizontally positioned lifting plate 2 is provided. The lifting plate 2 is connected to the top of the protective shell 1 via a first electric telescopic rod 3. A winding device 4 is located in the middle of the upper surface of the lifting plate 2. The winding device 4 is driven by a first motor 5, and a pull rope 6 is wound around it. The lifting plate 2 has a through hole 8 for the pull rope 6 to pass through. A side-scan sonar 9 is located below the lifting plate 2. The pull rope 6 passes through the through hole 8 and is connected to a hanging ring 10 on the side-scan sonar 9. A fixing clamp 11 for clamping the side-scan sonar 9 is also located below the lifting plate 2. Figure 3 As shown, the fixing clamp 11 includes clamping arms 12, driven wheels 13, driving wheels 14, a second motor 15, and a mounting frame 16. There are two clamping arms 12, with a driven wheel 13 fixedly connected to the upper end of each arm. The driven wheels 13 are rotatably mounted on the mounting frame 16, and the two driven wheels 13 mesh with each other. The mounting frame 16 also has a driving wheel 14, which meshes with one of the driven wheels 13. The driving wheel 14 is driven by the second motor 15. The mounting frame 16 is fixed to the lower surface of the lifting plate 2. Rotation of the driving wheel drives the driven wheel to rotate, thereby opening or closing the clamping arms to fix the side-scan sonar. The first motor and the second motor are reversible motors.

[0028] The device is equipped with a protective shell to protect the side-scan sonar. When the side-scan sonar is stored inside the protective shell, it is fixed to the lower part of the lifting plate by a fixing clip, preventing movement and avoiding the risk of damage due to accidental contact during transport. When measuring in complex areas with significant underwater topographical variations, the lifting plate can be extended beyond the protective shell via the first electric telescopic rod to conduct measurements, preventing environmental damage to the side-scan sonar during use. In areas suitable for towed measurement, the fixing clip can be released, and the side-scan sonar can be lowered into the water for measurement by releasing the winding device.

[0029] For example, the protective shell 1 is rectangular, and the baffle 17 is hinged to the long side of the bottom of the protective shell 1.

[0030] Specifically, there are two baffles 17, and the two baffles 17 are in a split-opening mode.

[0031] For example, there are two first electric telescopic rods 3, which are symmetrically connected to the lifting plate 2 and located on both sides of the winder 4.

[0032] For example, the side-scan sonar 9 is provided with 2-4 lifting rings 10, which are connected by a connecting rope 7, and the pull rope 6 is then connected to the connecting rope 7.

[0033] Specifically, the side-scan sonar 9 is equipped with three lifting rings 10, which form a triangular structure. The connection of the three lifting rings is more stable.

[0034] For example, the clamping arm 12 is an arc-shaped arm.

[0035] For example, there are two clamps 11, which can improve the stability of clamping.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
