Target recognition and automatic tracking technology, optoelectronic tracking servo control, control technology applications, mechanical structure design, and signal processing methods are key factors determining the quality of an optoelectronic tracking system. Currently, more advanced optoelectronic tracking systems typically incorporate sensors of various wavelengths and types, such as television, infrared, laser rangefinders, and goniometers. The system design must comprehensively consider factors such as operating range, atmospheric environment, target characteristics, optical aperture and focal length, stabilization accuracy, tracking accuracy, weight, and volume.

[0004] The existing technology has the following problems:

[0005] Over time, dirt can easily accumulate on the surface of a laser rangefinder, causing obstructions and affecting the accuracy of distance measurement, resulting in deviations. Summary of the Invention

[0006] This invention provides a ranging photoelectric tracking turntable to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A ranging photoelectric tracking turntable includes a photoelectric turret, an optical cabin on the photoelectric turret, a laser rangefinder on the optical cabin, a maintenance cover on the photoelectric turret, a cleaning device on the photoelectric turret, an energy-saving device on the photoelectric turret, and an anti-shake device on the photoelectric turret.

[0009] The cleaning device includes: a motor, which is fixedly connected to the inner wall of one side of the photoelectric turret; the output end of the motor is fixedly connected to a reciprocating lead screw via a coupling; and a movable plate is threaded onto the reciprocating lead screw.

[0012] The above technical solution incorporates a cleaning device to facilitate the wiping of dirt from the laser rangefinder, preventing deviations in the accuracy of optical tracking and ranging.

[0013] A further improvement of the technical solution of the present invention is that: the brush holder is adapted to the size of the laser rangefinder, and the mounting bracket is provided with a buckle assembly, which is adapted to the size of the brush holder.

[0014] A further improvement of the technical solution of the present invention is that the energy-saving device includes: a drive motor, the drive motor is fixedly connected to the outer wall of one side of the photovoltaic turret, the output end of the drive motor is fixedly connected to a rotating rod through a coupling, a spur gear is fixedly sleeved on the rotating rod, a toothed plate is meshed on the spur gear, a solar panel is fixedly connected to the top outer wall of the toothed plate, and a power supply board is fixedly connected to the inner wall of one side of the photovoltaic turret.

[0015] By adopting the above technical solution, the solution can prevent the equipment from continuing to operate in the event of circuit instability, short circuit or power failure during photoelectric tracking and ranging by setting up an energy-saving device. This avoids the power tripping causing calculation errors in precision equipment and affecting the actual accuracy.

[0016] A further improvement of the technical solution of the present invention is that: one end of the rotating rod is rotatably connected to the inner wall of one side of the photovoltaic turret through a bearing; the toothed plate is slidably connected to the inner wall of one side of the photovoltaic turret; the outer wall of one side of the toothed plate penetrates the inner wall of one side of the photovoltaic turret and extends to the outer wall of the photovoltaic turret; and the power plate is electrically connected to the solar panel.

[0017] A further improvement of the technical solution of the present invention is that the anti-shake device includes: a turret base, the turret base being slidably connected to the bottom outer wall of the photoelectric turret, a first damper being fixedly connected to one side outer wall of the turret base, a support frame being slidably connected to the bottom inner wall of the turret base, a second damper being fixedly connected to one side outer wall of the support frame, a slide rail frame being slidably connected to the side outer wall of the support frame, a third damper being fixedly connected to the bottom outer wall of the support frame, and a mounting plate being fixedly connected to the bottom outer wall of the slide rail frame.

[0020] A further improvement of the technical solution of the present invention is that: one end of the first damper is fixedly connected to the inner wall of one side of the photoelectric turret, one end of the second damper is fixedly connected to the outer wall of one side of the support frame, and one end of the third damper is fixedly connected to the top outer wall of the mounting plate.

[0021] A further improvement of the technical solution of the present invention is that: the optical cabin is opened on one side of the outer wall of the photoelectric turret, the laser rangefinder is fixedly installed on one side of the outer wall of the optical cabin, and the maintenance cover is snapped onto one side of the outer wall of the photoelectric turret.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0023] 1. This invention provides a ranging photoelectric tracking turntable. By turning on the motor, the reciprocating lead screw rotates, which drives the movable plate to move. The movable plate moves the mounting frame, which in turn moves the brush frame. The brush frame wipes and cleans the surface of the laser rangefinder, preventing dirt from obstructing the accuracy of optical tracking and ranging.

[0024] 2. This invention provides a distance measuring photoelectric tracking turntable. By activating the drive motor, the rotating rod rotates, which in turn drives the spur gear to rotate. The rotation of the spur gear drives the toothed plate to move, and the movement of the toothed plate drives the solar panel to move. The movement of the solar panel facilitates the periodic absorption of natural light and conversion into electrical energy to power the power supply panel for energy storage. This avoids the instability of the circuit, short circuit, or power failure during photoelectric tracking and distance measurement, and allows the equipment to continue operating. It also prevents power tripping from causing calculation errors in precision equipment and affecting the actual accuracy. At the same time, when not in use, the solar panel retracts into the interior of the photoelectric turret to prevent external damage.

[0025] 3. This invention provides a ranging photoelectric tracking turntable. When the photoelectric turntable is subjected to external interference or its own vibration, it moves. During the movement, it compresses the first damper and the first telescopic spring for lateral horizontal buffering. When moving vertically, it causes the turntable base to compress the second damper and the second telescopic spring for vertical horizontal buffering. When vibrating vertically, it causes the support frame to move and compress the third damper and the third telescopic spring for vertical buffering. By setting an anti-shake device, in optical tracking ranging, the tracking object is generally prone to some shaking when it is moving. Therefore, a certain amount of buffering is provided to reduce the inaccuracy of optical tracking ranging caused by shaking. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1:

[0036] like Figure 1 , 2 As shown in Figures 3, 4, and 5, this invention provides a ranging photoelectric tracking turntable, including a photoelectric turret 1, an optical cabin 2 mounted on the turret 1, a laser rangefinder 3 mounted on the optical cabin 2, a maintenance cover 4 mounted on the turret 1, a cleaning device 5 mounted on the turret 1, an energy-saving device 6 mounted on the turret 1, and an anti-shake device 7 mounted on the turret 1. The cleaning device 5 includes: a motor 51, which is fixedly connected to the inner wall of one side of the turret 1. The output end of the motor 51 is fixedly connected to a reciprocating lead screw 52 via a coupling. A movable plate 53 is threadedly connected to the reciprocating lead screw 52. The bottom outer wall of the movable plate 53 is fixedly connected to a mounting plate. Mounting bracket 55, with a brush holder 56 snapped onto one side of the outer wall of mounting bracket 55. A slide rail 54 is provided on the photoelectric turret 1, and a movable plate 53 is slidably connected to the inner side wall of the slide rail 54. A cleaning device 5 is provided to facilitate wiping away stains on the laser rangefinder 3, preventing deviations in the accuracy of optical tracking and ranging. The brush holder 56 is adapted to the size of the laser rangefinder 3. A buckle assembly 57 is provided on mounting bracket 55, and the buckle assembly 57 is adapted to the size of the brush holder 56. An optical cabin 2 is opened on one side of the outer wall of the photoelectric turret 1, and the laser rangefinder 3 is fixedly installed on one side of the outer wall of the optical cabin 2. An inspection cover 4 is snapped onto one side of the outer wall of the photoelectric turret 1.

[0037] In this embodiment, the reciprocating screw 52 is rotated by turning on the motor 51. The rotation of the reciprocating screw 52 drives the movable plate 53 to move. The movement of the movable plate 53 drives the mounting frame 55 to move. The movement of the mounting frame 55 drives the brush holder 56 to move. The movement of the brush holder 56 wipes and cleans the surface of the laser rangefinder 3, avoiding the phenomenon that dirt will obstruct the accuracy of optical tracking and ranging.

[0038] Example 2:

[0039] like Figure 1 , 2 As shown in Figures 3, 4, and 6, based on Embodiment 1, the present invention provides a technical solution: Preferably, the energy-saving device 6 includes: a drive motor 61, which is fixedly connected to the outer wall of one side of the photoelectric turret 1. The output end of the drive motor 61 is fixedly connected to a rotating rod 62 via a coupling. A spur gear 63 is fixedly sleeved on the rotating rod 62. A toothed plate 64 is meshed on the spur gear 63. A solar panel 65 is fixedly connected to the top outer wall of the toothed plate 64. A power board 66 is fixedly connected to the inner wall of one side of the photoelectric turret 1. By setting the energy-saving device 6, the equipment can continue to operate even when there is circuit instability, short circuit, or power failure during photoelectric tracking and ranging. This avoids the power tripping causing calculation errors in precision equipment and affecting the actual accuracy. One end of the rotating rod 62 is rotatably connected to the inner wall of one side of the photoelectric turret 1 via a bearing. The toothed plate 64 is slidably connected to the inner wall of one side of the photoelectric turret 1. The outer wall of one side of the toothed plate 64 penetrates the inner wall of one side of the photoelectric turret 1 and extends to the outer wall of the photoelectric turret 1. The power board 66 is electrically connected to the solar panel 65.

[0040] In this embodiment, the drive motor 61 is turned on to rotate the rotating rod 62. The rotation of the rotating rod 62 drives the spur gear 63 to rotate, which in turn drives the toothed plate 64 to move. The movement of the toothed plate 64 drives the solar panel 65 to move. The movement of the solar panel 65 facilitates the periodic absorption of natural light and conversion into electrical energy to power the power supply board 66 for energy storage. This prevents the equipment from continuing to operate even in the event of circuit instability, short circuit, or power failure during photoelectric tracking and ranging. It also prevents power tripping from causing calculation errors in precision equipment and affecting the actual accuracy. At the same time, when not in use, the solar panel 65 retracts into the interior of the photoelectric turret 1 to prevent external damage.

[0041] Example 3:

[0042] like Figure 1 , 2As shown in Figures 3, 4, and 7, based on Embodiment 1, the present invention provides a technical solution: Preferably, the anti-shake device 7 includes: a turret base 71, the turret base 71 being slidably connected to the bottom outer wall of the photoelectric turret 1, a first damper 72 being fixedly connected to one side outer wall of the turret base 71, a support frame 73 being slidably connected to the bottom inner wall of the turret base 71, a second damper 74 being fixedly connected to one side outer wall of the support frame 73, a slide rail frame 75 being slidably connected to the side outer wall of the support frame 73, a third damper 76 being fixedly connected to the bottom outer wall of the support frame 73, and a mounting plate 77 being fixedly connected to the bottom outer wall of the slide rail frame 75. By setting the anti-shake device... Device 7, in the case of optical tracking and ranging, generally the object being tracked and measured is in motion and is prone to some shaking. Therefore, a certain buffer is provided to reduce the shaking and cause inaccuracy in optical tracking and ranging. A first telescopic spring is fixedly connected to one side of the outer wall of the turret base 71, a second telescopic spring is fixedly connected to one side of the outer wall of the support frame 73, and a third telescopic spring is fixedly connected to the bottom outer wall of the support frame 73. One end of the first damper 72 is fixedly connected to one side of the inner wall of the photoelectric turret 1, one end of the second damper 74 is fixedly connected to one side of the outer wall of the support frame 73, and one end of the third damper 76 is fixedly connected to the top outer wall of the mounting plate 77.

[0043] In this embodiment, the photoelectric turret 1 moves when it is disturbed by external factors or shakes itself. During the movement, the first damper 72 and the first telescopic spring are squeezed for horizontal buffering. When moving horizontally, the turret base 71 is driven to squeeze the second damper 74 and the second telescopic spring for vertical buffering. When shaking vertically, the support frame 73 moves to squeeze the third damper 76 and the third telescopic spring for vertical buffering. By setting the anti-shake device 7, in the case of optical tracking and ranging, the tracking and ranging object is generally prone to shaking when it is moving. Therefore, a certain amount of buffering is provided to reduce the inaccuracy of optical tracking and ranging caused by shaking.

[0044] The working principle of a ranging photoelectric tracking turntable will be explained in detail below.

[0045] like Figure 1-6As shown, by turning on the motor 51, the reciprocating screw 52 rotates, which in turn moves the movable plate 53. The movable plate 53 moves the mounting frame 55, which in turn moves the brush holder 56. The brush holder 56 cleans the surface of the laser rangefinder 3, preventing dirt from obstructing the optical tracking and ranging accuracy. By turning on the drive motor 61, the rotating rod 62 rotates, which in turn moves the spur gear 63. The spur gear 63 moves the gear plate 64, which in turn moves the solar panel 65. The solar panel 65 periodically absorbs natural light and converts it into electrical energy to power the power board 66, storing the energy. This ensures that the equipment can continue to operate even in the event of circuit instability, short circuits, or power outages during photoelectric tracking and ranging, preventing power tripping. Precision equipment can cause calculation errors that affect actual accuracy. When not in use, the solar panel 65 retracts into the photovoltaic turret 1 to prevent external damage. The photovoltaic turret 1 moves when subjected to external interference or its own vibration. During this movement, the first damper 72 and the first telescopic spring provide lateral horizontal buffering. During vertical horizontal movement, the turret base 71 is driven to compress the second damper 74 and the second telescopic spring for vertical horizontal buffering. During vertical vibration, the support frame 73 moves to compress the third damper 76 and the third telescopic spring for vertical buffering. By setting up the anti-shake device 7, in optical tracking and ranging, the tracking object is generally prone to some shaking when in motion. Therefore, a certain amount of buffering is provided to reduce the inaccuracy caused by shaking in optical tracking and ranging.
