DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] like Figure 1-5 As shown, this embodiment provides a rotation positioning device for underwater communication equipment, the device comprising a driving mechanism 1 and a supporting rotation mechanism 2;

[0036] The driving mechanism 1 includes a sealed housing and a power source arranged inside the sealed housing; the sealed housing includes a motor sealed housing 3, a main base 5 with openings on both sides, and a sealing cover 6 and an output shaft end cover 8 respectively sealed and connected to the openings on both sides thereof; the main base 5 is a pressure-resistant housing, and together with the motor sealed housing 3, the connector mounting seat 4, the sealing cover 6 and the output shaft end cover 8, forms a completely sealed component with water pressure resistance. The main base 5 is a box structure with openings on both ends, and the openings on both sides are respectively sealed and connected to the sealing cover 6 and the output shaft end cover 8. The rear end face of the main base 5 is provided with two openings, which are respectively sealed and connected to the motor sealed housing 3 and the connector mounting seat 4. The motor 16 is installed inside the motor sealed housing 3 as a power source, and the connector mounting seat 4 is the external electrical connection interface of the rotary positioning device.

[0037] The worm gear 10 includes a worm and a turbine; the power output shaft of the motor 16 is coaxially connected to the worm, and the turbine is coaxially connected to the rotating shaft 7 to drive the rotating shaft 7 to rotate. The motor is connected to the worm gear 10, and the rotation speed of the motor 16 is reduced through the worm gear 10, and the rotation direction of the motor is changed so that the rotation direction of the rotating shaft 7 is perpendicular to the output shaft direction of the motor 16, effectively shortening the space of the driving mechanism 1.

[0038] The supporting rotating mechanism 2 includes a rotating shaft 7 and an adapter plate 18; one end of the rotating shaft 7 is connected to the driving source, and the other end passes through the sealed housing and is connected to the communication device through the adapter plate 18, and the power source drives the communication device to rotate around the axis of the rotating shaft 7 through the rotating shaft 7. The communication device 20 is installed on the horizontal part of the adapter plate 18 through the support member 19, so that when the rotating shaft 7 rotates, the communication device 20 can be driven to rotate around the axis of the rotating shaft 7 through the adapter plate 18 and the support member 19, so that the communication device 20 can be raised and then folded.

[0039] The shaft end cover 8, the bearing seat A9, the turbine, the bearing seat B11, and the sealing cover 6 are coaxially installed on the rotating shaft 7 from the outside to the inside; a switch baffle 14 and two switches 13 are provided on the outer end surface of the bearing seat B11. The switch baffle 14 has two baffle structures corresponding to the two switches 13 respectively, and the switch baffle 14 is coaxially fixedly sleeved on the rotating shaft 7 and rotates synchronously with the rotating shaft 7; the communication device 20 is prompted to be raised or folded into place through the cooperation of the switch 13 and the switch baffle 14. The two switches 13 are respectively used as a lifting-in-place switch and a folding-in-place switch. For example, when the shaft 7 rotates forward, the communication device 20 is lifted, and when the shaft 7 rotates reversely, the communication device 20 is folded. The two switches 13 are respectively arranged on the travel of the forward rotation and reverse rotation of the shaft 7. During the lifting process of the communication device 20, when the switch baffle 14 follows the shaft 7 to rotate forward synchronously to a set angle position, the lifting-in-place switch is triggered, and the motor 16 stops working. During the folding process of the communication device 20, when the switch baffle 14 follows the shaft 7 to rotate reversely synchronously to a set angle position, the folding-in-place switch is triggered, and the motor 16 stops working.

[0040] Two limit blocks 21 are set at set angles within the rotation range of the switch baffle 14, and one limit block 21 corresponds to one switch 13. The limit block 21 prevents the switch baffle 14 from continuing to rotate through its fixed position, thereby preventing the switch baffle 14 from exceeding the set rotation range, causing the communication equipment to exceed the working range and affecting the communication quality.

[0041] Furthermore, the supporting rotating mechanism 2 further comprises a supporting rod connecting flange 17; the vertical portion of the adapter plate 18 is coaxially connected to the rotating shaft 7 via the supporting rod connecting flange 17;

[0042] The bottom of the adapter plate 18 is connected to the support rod 19; the support rod 19 is connected to the communication device 20;

[0043] Furthermore, the main base 5 is provided with an interface for fixing to the underwater unmanned vehicle.

[0044] Working principle:

[0045] When the underwater unmanned vehicle is sailing underwater, the motor 16 drives the worm gear 10, and the turbine of the worm gear 10 drives the rotating shaft 7 to rotate, and then drives the communication device 20 to rotate around the axis of the rotating shaft 7 through the adapter plate 18 and the support member 19, so that the communication device 20 can be folded into the interior of the underwater unmanned vehicle without protruding from the baseline;

[0046] When the underwater unmanned vehicle is sailing on the water surface and needs to raise the communication equipment to a certain height above the water surface for communication, the motor 16 provides power as a power source. The motor 16 drives the communication equipment 20 to rotate around the axis of the rotating shaft 7 through the worm gear 10, so that the communication equipment 20 extends from the outer surface of the underwater unmanned vehicle.

[0047] During this process, the switch baffle 14 rotates synchronously with the rotating shaft 7. When the switch baffle 14 touches the switch 13 in the corresponding direction, the switch baffle 14 stops rotating. If the switch baffle 14 does not stop rotating, the limit block 21 prevents the switch baffle 14 from continuing to rotate.

[0048] After the communication operation is completed, the motor 16 rotates in the reverse direction, driving the communication device 20 to fold down to the inside of the aircraft baseline, and the communication device 20 returns to the inside of the aircraft. In this process, the stopped switch baffle 14 begins to rotate in the reverse direction under the influence of the rotating shaft 7. When the other switch 13 position is rotated, the switch baffle 14 stops again. If it fails to stop, another limit block 21 will prevent the switch baffle 14 from continuing to rotate.

[0049] Furthermore, as a component, the support rod 19 can be selected with different lengths according to the water surface conditions, which can change the working range of the communication device 20 and improve the environmental adaptability of the device.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
