Description

Technical Field

[0001] The utility model belongs to the technical field of photoelectric tracking, in particular to a photoelectric tracking device. Background Art

[0002] The optoelectronic tracking device is an integrated system of optics, mechanics, electronics, control and signal processing. It uses optoelectronic detection devices as sensitive elements and electromechanical control to keep the detector's visual axis stable, thereby realizing the tracking device's capture, tracking, aiming and stabilization functions for the target. Target recognition and automatic tracking technology, optoelectronic tracking servo control, control technology application, mechanical structure design, and signal processing methods are the key to determining the quality of optoelectronic tracking systems. Existing optoelectronic tracking equipment isolates the vibration of the carrier through a gyroscopic stabilized platform to obtain a relatively stable platform in inertial space. Driven by the image tracker output control instructions, the optoelectronic payload can search, capture, track and locate the target.

[0003] Existing photoelectric identification and tracking equipment is powerful and is generally installed in areas with harsh environments for monitoring. Due to the complex environment, the lens of the photoelectric tracking equipment is easily contaminated during long-term operation. In addition, water mist is easily condensed on the lens, resulting in poor quality of the collected images. In the prior art, manual regular maintenance is usually used to solve this problem. However, manual maintenance is inefficient. In seasons with changeable weather, the frequency of maintenance needs to be increased, which is time-consuming and labor-intensive.

[0004] A photoelectric tracking device is disclosed in the patent with publication number CN218830125U, which cleans the lens by designing a hot air outlet at the bottom of the tracking device to blow the lens. This design can effectively solve the problem of lens blurring caused by moisture, but it cannot effectively solve the problem of lens blurring caused by dust. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] An optoelectronic tracking device, such as Figures 1 to 4As shown, it includes a supporting component, an installation box 5, an electronic component and a cleaning component; wherein the supporting component is used to support the installation box 5 and drive the installation box 5 to move; the electronic component is arranged on the installation box 5; the electronic component includes a TV camera 6, an infrared thermal imager 7, a photoelectric indicator 8, a laser rangefinder 9 and a central processor 13;

[0028] The cleaning components include a driving motor 16, a driving gear 17, a mounting housing 15, a spring spring 18, a rotating rod 12, a driven gear 14 and a cleaning member 4; wherein the driving motor 16 and the mounting housing 15 are both fixedly connected in the mounting box 5; the driving gear 17 is fixedly connected to the output shaft of the driving motor 16, and the circumferential portion of the driving gear 17 has no meshing teeth; the spring spring 18 is connected in the mounting housing 15; one end of the rotating rod 12 is connected to the spring spring 18, and the other end extends out of the mounting box 5 and is connected to the cleaning member 4, which is used to clean the lens of the television camera 6; the driven gear 14 is fixedly connected to the rotating rod 12 and can mesh with the driving gear 17. The television camera 6 is used to collect images; the infrared thermal imager 7 is used to collect infrared images, the photoelectric indicator 8 is used to display the presence or absence of light signals to help users understand the state of the light signals, and the laser rangefinder 9 is used to measure distances. The central processor 13 is used to process the information obtained by the television camera 6, the infrared thermal imager 7, the photoelectric indicator 8, and the laser rangefinder 9, and can control the supporting components to drive the installation box 5 to move through the built-in algorithm to achieve tracking. It should be noted that the television camera 6, the infrared thermal imager 7, the photoelectric indicator 8, the laser rangefinder 9 and the central processor 13 all adopt existing technologies, so their specific structures will not be described one by one here.

[0029] Specifically, when in use, the initial position of the cleaning member 4 should not contact the lens of the television camera 6 and the end should face downward. When the lens of the television camera is contaminated or misted, the driving motor 16 is started, the driving motor 16 drives the driving gear 17 to rotate, the driving gear 17 drives the driven gear 14 to rotate, the driven gear 14 drives the rotating rod 12 to rotate, the rotating rod 12 drives the cleaning member 4 to rotate, the cleaning member 4 rotates upward and wipes the lens to achieve cleaning. At the same time, when the rotating rod 12 rotates, it also twists the clockwork spring 18 so that the clockwork generates elastic potential energy. When the driving gear 17 rotates to the part without meshing teeth, the meshing relationship between the driving gear 17 and the driven gear 14 is disconnected, the elastic potential energy of the clockwork spring 18 is converted into kinetic energy and drives the rotating rod 12 to rotate and reset, and the rotating rod 12 drives the cleaning member 4 to reset.

For example, a motor is set in the pitch rotating part 10, and the motor drives the installation box 5 to rotate so as to control the pitch angle. It should also be noted that the rotation angle of the rotating table 2 and the rotation angle of the pitch rotating part 10 are both controlled by the central processing unit 13.

The design of the block 3 can tighten the spring 18 for a period of time when the rotating rod 12 is installed, so that the rotating rod 12 can drive the cleaning member 4 to press against the block 3, which is conducive to the automatic reset of the cleaning member 4.

[0035] In a preferred embodiment, Figures 1 to 4 As shown, the part without meshing teeth in the circumferential direction of the driving gear 17 accounts for 1 / 2 to 1 / 3.
