DETAILED DESCRIPTION

[0014] The automatic sonar retracting and deploying device for an unmanned boat of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1 , 2 As shown, the automatic sonar retracting and releasing device for an unmanned boat of the present invention comprises a main body frame 28, a sonar 1, a retracting and releasing frame 29 and a driving device 2. A screw rod 3 is arranged inside the main body frame 28, a screw nut 4 matching the screw rod 3 is arranged on the inner side of the retracting and releasing frame 29, a slide rail 5 is arranged on the inner side of the main body frame 28, and a slider 6 matching the slide rail 5 is arranged on the outer side of the retracting and releasing frame 29. The sonar 1 is connected to the retracting and releasing frame 29, and the retracting and releasing frame 29 is connected to the screw rod 3 through the screw nut 4. The screw rod 3 is connected to the driving device 2, and driven by the screw nut 4, the sonar 1 is driven to move on the slide rail 5 through the slider 6.

[0016] The main body frame 28 includes a horizontal plate 14, a horizontal plate 2 15, and a main body side plate 16 connecting the two ends of the horizontal plate 14 and the horizontal plate 2 15 and extending to the bottom of the device. A vertical plate 17 and a vertical plate 2 18 are arranged between the horizontal plate 14 and the horizontal plate 2 15. The two common sides of the above-mentioned plates are respectively connected to the front plate 19 and the back plate 20. The back plate 20 is provided with a driving device 2 and has a connecting hole. The main body frame 28 is divided into a plurality of accommodating chambers by the above-mentioned plates. The upper accommodating chamber is provided with a watertight connector 22, a pair of bevel gears 21 and a displacement sensor 23. The pair of bevel gears 21 are respectively connected to the screw rod 3 and the driving device 2. The middle accommodating chamber is provided with a retractable frame 29 and a pair of bearing seats 27. The screw rod 3 passes through the retractable frame 29 and is installed in the bearing seat 27. The lower accommodating chamber is used to place the sonar 1. A limit block 26 is also arranged inside the main body frame 28. The limit block 26 is located at the lower end of the slide rail 5 and is used to limit the movement of the slider 6 and the retractable frame 29.

[0017] The retractable frame 29 includes an inner frame upper plate 7, an inner frame lower plate 8, and an inner frame side plate 9 connecting the inner frame upper plate 7 and the inner frame lower plate 8. The inner frame upper plate 7, the inner frame lower plate 8 and the inner frame side plate 9 are connected by angle plates 12. The screw nut 4 is arranged on the inner side of the inner frame upper plate 7, the slider 6 is arranged on the outer side of the inner frame side plate 9, the sonar 1 is connected to the outer side of the inner frame lower plate 8, and a conformal connecting plate 10 is also arranged on the outer side of the inner frame lower plate 8. A conformal connecting plate 11 is connected to the conformal connecting plate 10. The conformal connecting plate 11 has the same shape as the bottom plate of the boat to avoid generating additional resistance when not in use. Four connecting plates are also arranged around the sonar 1, which together with the conformal connecting plate 10 constitute the accommodating chamber of the sonar 1.

[0018] like Figure 3 As shown, the driving device 2 is located outside the main body frame 28 , and includes a motor 24 and a reducer 25 connected to each other, and the reducer 25 is connected to the bevel gear 21 .

[0019] When the sonar 1 needs to work, the motor 24 drives the reducer 25 to rotate forward, and then drives the screw 3 to rotate through the bevel gear 21 connected thereto, so that the retractable frame 29 slides on the slide rail 5, and at the same time drives the sonar 1, the conformal connecting plate 10 and the conformal plate 11 to move together, extending out of the bottom of the boat until the slider 6 reaches the limit block 26. After the sonar 1 finishes working, the motor 24 drives the reducer 25 to reverse until all components are completely recovered.
