Detailed Implementation

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, 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 this utility model and are not intended to limit this utility model.

[0026] See Figures 1-4 This utility model provides an underwater image sonar mounting bracket that can indicate direction and rotate freely, including: a fixed box 100, a rotating component 200 and a direction indicator component 300;

[0027] The fixed housing 100 is fixed to the towed body or the shore; when fixed to the shore, the device operates in a fixed-point image sonar observation mode; when fixed to a towed body such as a ship, the device operates in an image sonar observation mode that follows the ship's movement. As shown in the figure, the fixed housing 100 is preferably rectangular in shape.

[0028] The rotating component 200 is freely rotatable relative to the axial center of the fixed housing 100, and an underwater imaging sonar 500 is fixedly installed at the bottom of the rotating component 200.

[0029] The orientation indicator component 300 is disposed on the top of the rotating component 200 and the fixed housing 100, and is used to indicate the current orientation of the rotating component 200.

[0030] In this utility model, the rotating assembly 200 includes a rotating shaft 201 and a base 202; the fixed housing 100 is rectangular in shape, with a central hole at its center that matches the shape of the rotating shaft 201 and extends vertically through it; the upper part of the rotating shaft 201 is located inside the central hole, and the lower part of the rotating shaft 201 is located outside the central hole; the top end of the rotating shaft 201 passes through the central hole and extends above the top surface of the fixed housing 100; the diameter of the top end of the rotating shaft 201 is larger than the diameter of the central hole; the base 202, perpendicular to the rotating shaft 201, is fixedly mounted at the bottom of the rotating shaft 201; wherein, the rotating shaft 201 and the base 202 are detachably connected, specifically, as shown in... Figure 4 As shown, the bottom of the rotating shaft 201 has an external thread; a connecting seat 203 is fixedly mounted on the top surface of the base 202; the connecting seat 203 has an internal threaded hole that matches the external thread; the bottom of the rotating shaft 201 and the connecting seat 203 are threadedly connected. The design is detachable, which facilitates transportation and reduces the device's footprint.

[0031] The underwater imaging sonar 500 is fixedly mounted on the bottom surface of the base 202. Specifically, as shown... Figure 1 As shown, each of the four corners of the base 202 is provided with a mounting hole 2021 for stably mounting the underwater imaging sonar 500.

[0032] The underwater imaging sonar mounting bracket provided by this utility model can indicate the direction of observation. Whether in fixed-point observation mode or observation mode that follows the ship's movement, when the underwater imaging sonar 500 is immersed at a certain depth underwater, the rotating component 200 rotates freely around the fixed box 100 under the action of water flow, thereby driving the underwater imaging sonar 500 to rotate freely. Therefore, the underwater imaging sonar 500 can perform image sonar observation in different directions by rotating, thereby increasing the monitoring range and meeting the needs of multi-directional monitoring of the monitoring area, improving the accuracy and representativeness of the monitoring results.

[0033] To facilitate observers' understanding of the underwater image sonar 500's underwater location at any time, and to enable observers to promptly detect malfunctions such as equipment not rotating, this utility model also includes a location indicator component 300. The location indicator component 300 includes an angle scale 301 and an indicator rod 302. The angle scale 301 is arranged circumferentially around the central hole on the top surface of the fixed housing 100. The top end of the rotating shaft 201 is connected to one end of the horizontally oriented indicator rod 302, and the other end of the indicator rod 302 points towards the angle scale 301.

[0034] Therefore, when the rotating component 200 rotates around the fixed housing 100, it drives the indicator rod 302 to rotate synchronously and point to different scales on the angle dial 301, thus facilitating use by observers. For example, if observers find that the indicator rod 302 does not rotate within a certain period of time, they need to investigate the problem promptly.

[0035] Furthermore, the present invention may also include an adjustment component 400; the adjustment component 400 includes an adjustment rod 401 and a slide groove 402; the side wall of the fixed housing 100 is provided with the slide groove 402 communicating with the central hole, and the slide groove 402 is arranged horizontally; one end of the adjustment rod 401 is fixed to the outer wall of the rotating shaft 201, and the other end of the adjustment rod 401 passes through the slide groove 402 and extends to the outside of the slide groove 402.

[0036] The function of the adjustment component 400 is as follows: when it is necessary to perform image sonar observation of a fixed point, the operator can move the adjustment rod 401 to a specific position and insert rubber plugs into other positions in the slide groove 402, so that the adjustment rod 401 is maintained in this specific position, and the underwater image sonar 500 is used for azimuth observation. Therefore, by setting the adjustment component 400, the application range and flexibility of this device can be expanded to meet the needs of different image sonar observations.

[0037] This utility model provides an underwater imaging sonar mounting bracket that can indicate direction and rotate freely. The main body is made of high-strength alloy material, which ensures the overall strength and stability of the bracket. It can effectively support the sonar equipment, adapt to different installation environments, and has the advantage of a stable structure.

[0038] The underwater imaging sonar mounting bracket provided by this utility model, which can indicate azimuth and rotate freely, has the following advantages: it has multiple usage modes such as fixed azimuth observation or rotating multi-azimuth observation, which expands the application range and flexibility of the device and meets the needs of different operation scenarios for sonar detection angles. In particular, for the rotating multi-azimuth observation mode, it can improve the monitoring range and improve the accuracy and representativeness of the monitoring results.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
