Description

Technical Field

[0001] The invention relates to the field of photoelectric turret brackets, in particular to a multi-axis linkage rotating bracket for a photoelectric tower. Background Art

[0002] As an important optoelectronic detection and observation equipment, optoelectronic tower (also known as optoelectronic turret) plays a key role in many fields such as military, security, aerospace, and ocean monitoring. Its development history is closely related to the evolution of related technologies, and it is gradually improved to meet the ever-increasing needs of target detection, tracking, and situational awareness.

[0003] At present, the optoelectronic turrets used in the market generally include optical systems, turntable structures, electronic systems, etc. With the cooperation of the above systems, the optoelectronic turret can be stably installed on the equipment in use, and adjust its own state according to the needs to complete the monitoring of the target. The structure of the optoelectronic turret can refer to an integrated optoelectronic turret disclosed in a Chinese patent with the publication number CN111664329B, which includes an optoelectronic stabilization platform, an optoelectronic load, an electrical subsystem, and a laser drive and temperature control component; the optoelectronic stabilization platform is used to carry the optoelectronic load; the electrical subsystem is used to supply power and servo control the optoelectronic stabilization platform and image processing the optoelectronic load; the optoelectronic load is used to meet the target detection function in different environments; the laser drive and temperature control component is used to control the laser drive and temperature of the cat's eye detection unit and the laser suppression unit. The above-mentioned optoelectronic turret is integrated in the functional units such as visible light detection, cat's eye detection, laser suppression, and laser ranging to achieve the reuse of structure and function, and is highly correlated from the transmitting and receiving aperture to the back-end centralized information processing and countermeasure implementation, realizing the organic integration of multiple functions, with high system integration and more complete functions, meeting the application needs of various forms of target detection in increasingly complex environments.

[0004] When using the optoelectronic turret provided by the above patent, or other similar optoelectronic turrets, they are often fixedly installed on the equipment being used, and once installed, their position remains fixed. In practical applications, this brings many inconveniences and performance limitations. For example, in military reconnaissance missions, if the optoelectronic turret uses a fixed bracket, its optical equipment can only face a specific direction, and it is impossible to adjust the viewing angle in time according to changes in the battlefield situation and the orientation of the target, which may lead to missing the opportunity to detect and track important targets. In addition, in military reconnaissance missions, because the optoelectronic turret is fixedly installed relative to the equipment being used, the state of the optoelectronic turret will also change during the process of changing the posture of the equipment being used, affecting the detection of the target. For example, after the optoelectronic turret is installed on a reconnaissance aircraft, when the aircraft's posture changes, the optoelectronic turret will synchronously change and tilt, which can easily cause the optoelectronic turret to deviate from a good detection state.

DETAILED DESCRIPTION

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following is a further description with reference to the accompanying drawings and specific embodiments: In order to ensure that the operation of the optoelectronic turret is not affected when the posture of the device is changed, this embodiment provides a bracket for the optoelectronic turret, which can adjust the state of the optoelectronic turret as needed to reduce the impact of changes in the posture of the device.

[0023] The bracket directly replaces the bracket of the existing photoelectric turret, and supports the photoelectric turret to be stably installed on the device in use. Specifically, the bracket includes a connecting component and a leveling mechanism 2. The connecting component is installed on the photoelectric tower body 1, and the operation of the connecting component can control the horizontal and vertical rotation of the photoelectric tower body 1, that is, to achieve spatial adjustment of the photoelectric tower body 1. The leveling mechanism 2 is arranged above the connecting component and is directly connected to the device in use. Through its operation, the state of the connecting component can be adjusted, and then the state of the photoelectric tower body 1 can be adjusted. In cooperation with the connecting component, the optical equipment of the photoelectric turret can achieve precise pointing adjustment in three-dimensional space according to the position change of the target. Compared with the bracket of the existing photoelectric turret, it can make the photoelectric tower body 1 have a larger rotation range, Before introducing the specific bracket, a brief introduction to the photoelectric tower body 1 is given. The specific photoelectric tower body 1 includes an optical system, an electronic system, a gyroscope, etc. The optical system includes a visible light camera, an infrared thermal imager, and a laser rangefinder. The visible light camera uses a high-quality optical lens and a CCD (charge coupled device) or CMOS (complementary metal-oxide-semiconductor) image sensor to obtain high-resolution visible light images. The focal length, aperture and other parameters of the lens can be adjusted according to different application scenarios to meet the needs of long-distance observation or wide-area search. The infrared thermal imager is based on an infrared detector and can detect the thermal radiation of the target and convert it into a visual thermal image. Infrared thermal imagers are divided into cooled and uncooled types. The cooled thermal imager has higher sensitivity and resolution, but it is more expensive and has a complex structure. It is usually used in military and other fields with higher performance requirements; the uncooled thermal imager has a lower cost and a smaller size, and is suitable for some civil and industrial fields with slightly lower performance requirements. The laser rangefinder calculates the target distance by emitting a laser beam and measuring the time it takes for the laser to travel back and forth to the target. Laser rangefinders can provide high-precision distance data. When used in conjunction with optical cameras and thermal imagers, they can accurately determine the location information of the target. The electronic system includes a signal processing unit, a data transmission unit, a control system, etc. The signal processing unit is responsible for processing the image signal and the laser ranging signal obtained by the optical system. It includes operations such as image enhancement, filtering, and target extraction to improve the quality and recognizability of the signal. For example, the thermal image obtained by the infrared thermal imager is subjected to noise reduction processing to make the thermal characteristics of the target clearer. The data transmission unit transmits the processed signal data to the control center or other display devices. Wired (such as optical fiber, cable, etc.) or wireless (such as microwave communication, satellite communication, etc.) transmission methods can be used. In wireless transmission, factors such as bandwidth, stability, and confidentiality of data transmission should be considered. The control system realizes the overall control of the optoelectronic turret, including the rotation angle of the turntable, the focal length adjustment of the optical device, and the switching of the working mode. The control system can be operated by manual operation (such as joystick, button, etc.) or automatic control (such as according to a preset scanning mode or tracking algorithm). Gyroscopes can be integrated with optical devices (such as visible light cameras, infrared thermal imagers, etc.) in a module. This allows the gyroscope to be closer to the viewing angle of the observed target and better perceive the motion state of the optical system. For example, in some miniaturized optoelectronic turrets, the gyroscope is integrated inside the housing of the optical device and is closely combined with optical lenses and other components to form a compact observation module.

[0024] In order to be able to adjust the position of the photoelectric tower body 1 relative to the equipment in use and avoid affecting the detection effect due to changes in the posture of the equipment in use, the leveling mechanism 2 includes a bottom ring plate 21, a top ring plate 23 and multiple adjustment devices 24. The upper and lower ends of the multiple adjustment devices 24 are respectively hingedly connected to the bottom ring plate 21 and the top ring plate 23. The adjustment devices 24 adjust their own states through their operation, and then adjust the relative positions of the bottom ring plate 21 and the top ring plate 23, thereby achieving overall precise positioning and complex movements, demonstrating its advantages in achieving precise motion control in three-dimensional space.

[0025] Specifically, the adjusting device 24 includes a connecting plate 242, a steering gear 241 and a connecting frame 243. The steering gear 241 is hingedly arranged at the top of the connecting plate 242, and the connecting frame 243 is hingedly arranged at the bottom of the connecting plate 242. The connecting plate 242 can be controlled to rotate around the axis by the operation of the steering gear 241, thereby adjusting the position of the connecting frame 243. In order to adjust the relative position of the top ring plate 23 and the bottom ring plate 21 when the steering gear 241 is working, end shafts 244 are arranged on the sides of the steering gear 241 and the connecting frame 243 that are away from each other. The end shafts 244 distributed up and down are respectively connected and inserted into the bottom ring plate 21 and the top ring plate 23 through bearings. Therefore, when the steering gear 241 is working to adjust the inclination angle of the connecting plate 242, the relative position of the bottom ring plate 21 relative to the top ring plate 23 is adjusted. In actual manufacturing, the adjusting device 24 may also be replaced with a telescopic cylinder, such as an electric cylinder or a hydraulic cylinder, and the relative positions of the top ring plate 23 and the bottom ring plate 21 may be adjusted by the telescopic operation of the telescopic cylinder. Example

[0026] like Figure 1-8As shown, under the premise of being able to adjust the position of the photovoltaic tower body 1 relative to the use equipment, in order to realize the rotation angle of the photovoltaic tower body 1 in space, the connection component can be provided with a first connection component 3. The first connection component 3 includes a connecting ball 32, a supporting device 34 and a first motor 31. The supporting device 34 is arranged below the bottom ring plate 21, and the connecting ball 32 is arranged through the supporting device 34, and the top of the connecting ball 32 protrudes from the bottom ring plate 21. Therefore, under the action of the supporting device 34, the connecting ball 32 is stably arranged on the bottom ring plate 21, and at the same time, the connecting ball 32 is provided with support for the rotation of the connecting ball 32 under the action of external force. In addition, a mounting groove 322 is arranged at the top of the connecting ball 32, and a second motor 323 is arranged at the mounting groove 322. The second motor 323 is connected to the top plate 11 at the top of the photovoltaic tower body 1. Therefore, under the action of the second motor 323, the photovoltaic tower body 1 can be controlled to rotate around the axis, that is, when the connecting ball 32 is installed statically, the photovoltaic tower body 1 can be controlled to rotate on the horizontal plane. At the same time, the first motor 31 is fixedly arranged on the bottom ring plate 21, and a first driving wheel 33 is arranged at the end. Two first driving wheels 33 are arranged and distributed on both sides of the center of the connecting ball 32. At the same time, the first driving wheel 33 is arranged in contact with the top of the connecting ball 32. Therefore, when the first motor 31 is working, the connecting ball 32 can be controlled to rotate on the vertical plane. In summary, with the cooperation of the first motor 31 and the second motor 323, the photoelectric tower body 1 can be controlled to rotate in a large range in space, providing support for target detection. In actual production, a gear box (such as a reducer) can be installed at the end of the first motor 31 and the second motor 323, and the power is transmitted to the driving wheel or the photoelectric tower body 1 through the gear box to ensure that it can still rotate smoothly when the load (such as optical systems and other electronic equipment) is heavy. In addition, in order to control the rotation of the photoelectric tower body 1 through the driving wheel, a rubber layer can be set on the driving wheel to increase the friction coefficient between the driving wheel and the photoelectric tower body 1.

[0027] In order to stably install the connecting ball 32 on the bottom ring plate 21, the supporting device 34 includes an outer ring plate 341, an inner ring plate 342 and a curved plate 343. The inner ring plate 342 is fixedly arranged on the top of the curved plate 343, and the outer ring plate 341 is sleeved on the outer side of the inner ring plate 342 through a bearing connection. A stud 22 is arranged below the bottom ring plate 21, and the stud 22 penetrates the outer ring plate 341. The inner diameter of the upper end of the curved plate 343 is larger than the inner diameter of the lower end, so the connecting ball 32 is directly supported on the curved plate 343, and with the cooperation of the first driving wheel 33, the connecting ball 32 is stably installed relative to the curved plate 343. An arc-shaped clamping plate 344 is provided on the inner side surface of the curved panel 343, and an arc-shaped clamping groove 321 is provided on the connecting ball 32. The arc-shaped clamping plate 344 extends into the arc-shaped clamping groove 321 to limit the rotation of the connecting ball 32. In this embodiment, the connecting ball 32 is limited to rotate on the vertical plane to avoid affecting the rotation of the photovoltaic tower body 1 on the horizontal plane.

[0028] In order to reduce the friction between relatively moving devices, the devices can be made of materials with low friction coefficients, such as polytetrafluoroethylene (PTFE), or graphite-based composite materials. The relatively moving devices can also be surface treated, such as polishing, or coated with a low friction coefficient coating (such as Teflon coating). Example

[0029] like Figure 9-19 As shown, under the premise of being able to adjust the position of the photovoltaic tower body 1 relative to the use equipment, in order to realize the rotation angle of the photovoltaic tower body 1 in space, the connection component can be set as a second connection component, and the second connection component includes an adjustment mechanism 4 and a connection frame 5. The connection frame 5 is set as an arc structure, and the central angle of the circle is greater than 180°. At the same time, it is sleeved on the photovoltaic tower body 1. Therefore, the photovoltaic tower body 1 is stably installed relative to the connection frame 5, and it is convenient for the photovoltaic tower body 1 to rotate under the action of external force. The adjustment mechanism 4 is set on the side of the connection frame 5 and contacts with the photovoltaic tower body 1. Therefore, through the control of the adjustment mechanism 4, the photovoltaic tower body 1 can be controlled to rotate vertically and horizontally upward to achieve the adjustment of the direction of the photovoltaic tower body 1.

[0030] In order to be able to install the connecting frame 5 on the photovoltaic tower body 1, the connecting frame 5 includes a main board 55 and a plurality of bonding plates 54. The central angles of the main board 55 and the bonding plates 54 are both less than 180°, and the plurality of bonding plates 54 are detachably arranged on the sides of the main board 55. Therefore, when installing the connecting frame 5 and the photovoltaic tower body 1, first, the connecting frame 5 is placed on the photovoltaic tower body 1, and then the plurality of bonding plates 54 are installed one by one on the main board 55.

[0031] In order to realize the detachable connection between the bonding plate 54 and the main board 55, a plate 553 is fixedly arranged at the end of the main board 55, a threaded column 554 is threadedly arranged at the top of the plate 553, and a disk body is sleeved at the bottom of the threaded column 554. A slide groove 551 is arranged on the side wall of the plate 553, and an inlet and outlet groove 552 is arranged at the top of the slide groove 551. At the same time, a plurality of horizontal plates 541 are fixedly arranged on the bonding plate 54, and a baffle 542 is arranged in the gap between adjacent horizontal plates 541, one of the horizontal plates 541 is provided with a connecting groove 543, and the other horizontal plates 541 are fixedly provided with a slide plate 544. During installation, the plate 553 is placed on multiple horizontal plates 541, and the baffle 542 is in direct contact with the plate 553. At the same time, the slide plate 544 passes through the entry and exit grooves 552 and is installed in the slide groove 551, and the disk body is located in the connecting groove 543. This arrangement realizes a stable and detachable connection between the bonding plate 54 and the main board 55, and by rotating the threaded column 554, the bonding plate 54 can be controlled to rise and fall relative to the plate 553, which provides convenience for setting the bonding plate 54 on the outside of the photovoltaic tower body 1.

[0032] In order to reduce the friction between relatively moving devices, the devices can be made of materials with low friction coefficients, such as polytetrafluoroethylene (PTFE), or graphite-based composite materials. The relatively moving devices can also be surface treated, such as polishing, or coated with a low friction coefficient coating (such as Teflon coating).

[0033] In order to stably install the adjustment mechanism 4 on the side of the connecting frame 5, and the connecting frame 5 can be stably connected to the bottom ring plate 21. A central shaft 51 is fixedly arranged at the end of the connecting frame 5, an annular groove 53 is arranged at the end of the central shaft 51, and a bolt is inserted into the end surface thread, and a support plate 25 is fixedly arranged on the side of the bottom ring plate 21. The support plate 25 is set as an L-shaped structure, and a through hole is set at the bottom. The support plate 25 is sleeved at the annular groove 53, and the bolt head is set to press the support plate 25. This arrangement can realize the stable and detachable connection between the connecting frame 5 and the support plate 25. The adjustment mechanism 4 includes a flower rack 41, a snap column 411 is provided at the through hole in the middle of the flower rack 41, a snap groove 52 is provided on the central axis 51, and a fastening screw 251 is threadedly penetrated on the support plate 25, the flower rack 41 is sleeved on the central axis 51, the snap column 411 is located in the snap groove 52, limiting the stable installation of the flower rack 41 relative to the connecting frame 5, and the end of the fastening screw 251 presses against the flower rack 41 to force the flower rack 41 to fit the connecting frame 5.

[0034] In order to be able to control the photoelectric tower body 1 to rotate and adjust the direction under the operation of the adjustment mechanism 4, the adjustment mechanism 4 also includes a second driving wheel 443, a limiting wheel 421, a third motor 43 and a fourth motor 44. The second driving wheel 443 and the limiting wheel 421 are arranged on one side of the flower rack 41, and are staggered with the connecting frame 5, and are in contact with the photoelectric tower body 1. Therefore, the photoelectric tower body 1 can be controlled to rotate by the rotation of the second driving wheel 443, and at the same time, under the action of the limiting wheel 421, the non-rotating photoelectric tower body 1 is stably installed relative to the connecting frame 5. The third motor 43 and the fourth motor 44 are both arranged on the other side of the flower rack 41. Under the operation of the third motor 43, the limiting wheel 421 and the second driving wheel 443 can be controlled to change their directions, providing support for controlling the photoelectric tower body 1 to rotate along the preset direction. Under the action of the fourth motor 44, the second driving wheel 443 can be controlled to rotate, providing power for realizing the rotation of the photoelectric tower body 1. In addition, in order to control the rotation of the photoelectric tower body 1 through the driving wheel, a rubber layer can be provided on the driving wheel to increase the friction coefficient between the driving wheel and the photoelectric tower body 1.

[0035] Specifically, the limiting wheel 421 and the second driving wheel 443 are respectively mounted on their respective support frames 422, and a coupling is fixedly arranged at the end of the support frame 422, and the coupling is connected through the flower frame 41 through a bearing. The ends of the couplings of the limiting wheel 421 and the second driving wheel 443 protruding from the flower frame 41 are respectively sleeved with the first sprocket 423 and the second sprocket 442, and the third motor 43 is mounted on the flower frame 41, and the output shaft is arranged through the flower frame 41, and the end is provided with a third sprocket, and the first sprocket 423, the second sprocket 442, and the third sprocket are connected by a chain, so that under the action of the third motor 43, the limiting wheel 421 and the second driving wheel 443 can be controlled to rotate and adjust the direction. A frame 441 is fixedly arranged at the end of the second driving wheel 443, and a transmission shaft 445 is arranged through the edge of the frame 441. One end of the transmission shaft 445 is connected to the central axis of the second driving wheel 443 through a transmission gear 444, and the other end is connected to the fourth motor 44 through a chain. The fourth motor 44 is installed on the frame 441. Therefore, under the operation of the fourth motor 44, the second driving wheel 443 can be controlled to rotate, that is, the photovoltaic tower body 1 can be controlled to rotate.
