With the rapid development of technology, photoelectric turntables have made great breakthroughs in performance, application scope, and use effect. Photoelectric turntables used in ships are usually installed at a high place on the ship to obtain a wider field of view. Under strong wind and wave conditions, the violent shaking and vibration of the ship will pose a challenge to the locking of the photoelectric turntable. However, in the prior art, the lock for locking the photoelectric turntable adopts a design of clearance fit between the locking shaft and the locking hole. Although it is easy to lock and has low requirements for the alignment accuracy of the locking shaft and the locking hole, it is difficult to provide sufficient stability in such a lock in a dynamic environment. Specifically, the larger assembly gap makes the lock easy to loosen in the locked state, that is, the "swimming" phenomenon, which in turn causes vibration and impact, which is likely to cause the photoelectric turntable to vibrate under the locked condition, and even cause damage to the photoelectric turntable.

[0044] See also Figure 1-3 To describe this embodiment, the utility model provides an automated precision locking device and an optoelectronic turntable for a ship, the automated precision locking device comprises a lifting structure, an automatic locking bracket 2, a driving member 3, a guide pipe 4, a fixing seat 5 and a locking shaft 6, the lifting structure can drive the automatic locking bracket 2 to lift and lower; the driving member 3 is fixedly arranged on the automatic locking bracket 2; the guide pipe 4 is transmission-connected with the driving member 3, the driving member 3 can drive the guide pipe 4 to rotate, and the guide pipe 4 is provided with a first threaded hole; the fixing seat 5 is provided with a second threaded hole; the extension direction of the second threaded hole is on the same straight line as the extension direction of the first threaded hole; the two ends of the locking shaft 6 can be screwed with the first threaded hole and the second threaded hole respectively.

[0045] The automated precision locking device, when locking is required, the lifting structure drives the automatic locking bracket 2, the driving member 3, the guide pipe 4 and the locking shaft 6 to rise together until the upper end of the locking shaft 6 abuts against one end of the second threaded hole of the fixed seat 5, and then the driving member 3 drives the guide pipe 4 to rotate. It can be understood that the outer periphery of the locking shaft 6 is provided with an external thread. Since at this time one end of the locking shaft 6 is screwed with the guide pipe 4 and the other end abuts against the entrance of the second threaded hole, when the guide pipe 4 rotates, the locking shaft 6 will rotate and move upward and be screwed into the second threaded hole. After the two ends of the locking shaft 6 are respectively screwed into the first threaded hole and the second threaded hole, the driving member 3 stops driving the guide pipe 4. Since the fixed seat 5 is fixedly set on the pitch frame 200, and the lifting structure is set on the azimuth base 100, the two ends of the locking shaft 6 are respectively screwed into the first threaded hole and the second threaded hole, so that the relative position of the azimuth base 100 and the pitch frame 200 can be fixed, thereby achieving a tighter connection than the clearance fit of the traditional shaft and hole, and effectively reducing shaking and vibration.

[0046] like Figure 1 As shown, optionally, the automated precision locking device further includes a positioning sleeve 7, the positioning sleeve 7 is located above the guide pipe 4, the locking shaft 6 is passed through the positioning sleeve 7, and the positioning sleeve 7 can abut against the fixing seat 5. The lifting structure drives the positioning sleeve 7 and the automatic locking bracket 2, the driving member 3, the guide pipe 4 and the locking shaft 6 to rise together. When the upper end of the positioning sleeve 7 abuts against the fixing seat 5, the locking shaft 6 abuts against the entrance of the second threaded hole. The design of the positioning sleeve 7 can make the locking shaft 6 better align with the second threaded hole. First, use the positioning sleeve 7 to position the locking shaft 6, and then start the driving member 3 to drive the guide pipe 4 to rotate.

[0047] Optionally, the positioning sleeve 7 is provided with a tapered hole 71, the fixing seat 5 is provided with a tapered boss 51, and the tapered hole 71 can be sleeved on the tapered boss 51. When the positioning sleeve 7 is used for positioning, the positioning sleeve 7, the guide channel and the locking shaft 6 move upward together, and the inner wall of the tapered hole 71 of the positioning sleeve 7 abuts and fits with the outer wall of the tapered boss 51 of the fixing seat 5, which makes positioning easier, provides better positioning accuracy and stability than traditional cylindrical shafts, reduces the risk of breakage, and has a lower risk of breaking in the middle.

When the locking shaft 6 is screwed with the second threaded hole and rises to the set position, the electromagnet 81 is energized, and the electromagnet 81 absorbs the reinforcement sleeve 82 and moves upward. When the reinforcement sleeve 82 is magnetically attracted to the electromagnet 81, the abutment ring 821 is located below the abutment step 72 and abuts against the abutment step 72, which can further enhance the ability of the locking shaft 6 to resist shear force and avoid the risk of the locking shaft 6 being cut off.

[0049] When the locking state needs to be released, the electromagnet 81 is powered off to lose its magnetism, so that the reinforcing sleeve 82 moves downward under the action of gravity, the electromagnet 81 is separated from the reinforcing sleeve 82, and the abutting ring 821 is separated from the abutting step 72.

[0050] Optionally, the electromagnetic reinforcement structure further includes an electromagnet switch 83 , which is disposed on the fixing seat 5 , and is used to control the electromagnet 81 to be powered on or off.

[0051] Optionally, the lifting structure includes a linear slide 11 and a slider 12 , the linear slide 11 can drive the slider 12 to rise and fall, and the slider 12 is fixedly connected to the automatic locking bracket 2 .

[0052] like Figure 1 As shown, optionally, an upper limit block 13 and a lower limit block 14 are respectively provided at both ends of the linear slide 11, and the slider 12 can abut against the upper limit block 13 or the lower limit block 14. The upper limit block 13 and the lower limit block 14 are used to limit the slider 12, and can prevent the slider 12 from detaching from the linear slide 11.

At this time, the upper end of the locking shaft 6 abuts against the entrance of the second threaded hole. After positioning is completed, the motor drives the guide pipe 4 to rotate, and the first threaded hole inside the guide pipe 4 drives the locking shaft 6 to move upward. The locking shaft 6 is screwed and raised with the second threaded hole of the positioning seat.

After the locking shaft 6 rises to the set position, the electromagnet switch 83 is turned on, the electromagnet 81 is energized, and the reinforcement sleeve 82 is adsorbed and moved upward. When the reinforcement sleeve 82 is magnetically attracted to the electromagnet 81, the abutment ring 821 is located below the abutment step 72 and abuts against the abutment step 72, further reinforcing the locking, and preventing the shear force from cutting off the locking shaft 6. When unlocking is required, the electromagnet switch 83 is turned off, the electromagnet 81 loses its magnetism, the reinforcing sleeve 82 moves downward under the action of gravity, the electromagnet 81 separates from the reinforcing sleeve 82, and the abutting ring 821 separates from the abutting step 72. The motor rotates in the opposite direction, the motor drives the guide sleeve to rotate in the opposite direction, and the locking shaft 6 moves downward until the end of the locking shaft 6 reaches the entrance of the second threaded hole, after which the slider 12 moves downward, and the positioning sleeve 7 separates from the fixing seat 5.

[0057] The automated precision locking device improves the stability of the optoelectronic turntable in severe sea conditions, reduces the possibility of locking vibration and damage to the optoelectronic turntable caused by wind and waves, enhances the reliability and safety of the optoelectronic turntable, and extends the service life of the optoelectronic turntable.
