[0037] See Figure 1 as well as Figure 2 , Figure 1A schematic diagram of the imaging adjustment device according to one embodiment of this application is shown. Figure 2 This illustration shows a schematic diagram of the shooting adjustment device from another perspective in one embodiment of this application. The shooting adjustment device provided in one embodiment of this application specifically includes: a first cavity 2, with mounting plates respectively disposed on both sides of the first cavity 2, the mounting plates being on the same plane for fixed connection to the train via screws; a second cavity 5, with a first side of the second cavity 5 screwed to the first end face of the first cavity 2; a motor 1, the motor 1 being disposed within the first cavity 2; a worm gear 18 and a turbine 19, the worm gear 18 and the turbine 19 being disposed within the second cavity 5, one end of the worm gear 18 being keyed to the output shaft of the motor 1; the turbine 19 being meshed with the worm gear 18; and a rotating shaft 17, the turbine 19 being sleeved on the rotating shaft 17, with both ends of the rotating shaft 17 passing through the second cavity. The circular holes on both ends of the second cavity 5 extend to the outside of the second cavity 5; two rotating brackets (first rotating bracket 12 and second rotating bracket 16) are located outside the second cavity 5, and one end of each bracket is fixedly connected to the rotating shaft 17 extending outside the second cavity 5; a connecting plate 13 is located outside the second cavity 5 and is fixedly connected to the other end of the two rotating brackets, and the connecting plate 13 is used to mount the shooting equipment; the motor 1 is used to drive the output shaft to rotate, which in turn drives the worm gear 18 to rotate, which in turn drives the turbine 19 to rotate, which in turn drives the rotating shaft 17 to rotate, which in turn drives the rotating bracket to rotate, so that the connecting plate 13 rotates outside the second cavity 5 to adjust the angle of the shooting equipment mounted on the connecting plate 13.
[0038] The term "shooting adjustment device" can refer to the entire device used to adjust the angle of the shooting equipment (such as a camera or video camera). "First cavity 2" can refer to a main housing structure within the device, used to house and protect the motor 1. "Mounting plate" can refer to the flat plate structures located on both sides of the first cavity 2. Being on the same plane, this design ensures the device can fit flat and securely onto the mounting surface (such as a train body). "Screw connection" can refer to a common mechanical fastening method, using screws and nuts (or threaded holes) to fasten two or more components together; here, it can refer to the mounting plate being fixed to the train by screws, and the connection between the first cavity 2 and the second cavity 5 also being secured by screws. "Second cavity 5" can refer to another main housing structure within the device, used to house and protect the worm gear 18, turbine 19, and the rotating shaft 17. "Mount 1" can refer to the device providing rotational power (usually an electric motor), the source of the entire adjustment action, and is installed within the first cavity 2. The worm 18 can refer to a special type of screw with a thread shape similar to a snail's spiral. It is usually used in conjunction with the turbine 19 to form a turbine 19-worm 18 transmission pair. The rotational motion of the worm 18 drives the rotation of the turbine 19. A meshing connection refers to the interlocking contact between the helical teeth of the worm 18 and the teeth of the turbine 19, thereby transmitting motion and power. A keyed connection refers to a mechanical connection method used to transmit torque between a shaft (e.g., the output shaft of motor 1) and a part fitted onto the shaft (e.g., the worm 18). Typically, matching keyways are machined on the shaft and the hole, and then a metal block (key) with a rectangular cross-section is embedded. The rotating shaft 17 can refer to a shaft that passes through the second cavity 5. The turbine 19 is fixed (fitted) onto this shaft, so the rotation of the turbine 19 directly drives the rotating shaft 17 to rotate. A circular hole can refer to a hole machined on the two end faces of the second cavity 5, allowing the two ends of the rotating shaft 17 to pass through and extend to the outside of the second cavity 5. The rotating brackets can refer to two rigid connecting parts located outside the second cavity 5, one end of which is fixedly connected to both ends of the rotating shaft 17 extending from the second cavity 5. Therefore, the rotation of the rotating shaft 17 will cause the two brackets to rotate synchronously. The connecting plate 13 can refer to a flat plate structure located outside the second cavity 5, used for directly mounting shooting equipment (such as a camera gimbal or the camera itself). It is fixedly connected to the other end of the two rotating brackets. The shooting equipment can refer to equipment that needs to be adjusted in angle, such as a camera, camcorder, or surveillance camera.
[0039] In this embodiment, the control logic of the shooting adjustment device is a chain transmission process, the core of which is: electrical signal - motor 1 rotation - worm gear 18 and turbine 19 deceleration and torque increase - rotating shaft 17 output - bracket swing - connecting plate 13 angle change; specifically, the external control system (such as the train control system connected to the shooting adjustment device) sends a start signal to motor 1. After receiving the signal, motor 1's output shaft starts to rotate; the output shaft of motor 1 directly transmits the rotational motion and torque to worm gear 18 through a key connection, and worm gear 18 starts to rotate; the rotation of worm gear 18 is transmitted through the turbine 19... The meshing connection drives the turbine 19 to rotate; the characteristics of the turbine 19 and worm gear 18 transmission include: the speed of the turbine 19 is much lower than that of the worm gear 18 (large reduction ratio), which can increase the output torque; the low-speed output end (turbine 19) obtains a large torque, which can drive the load (shooting equipment); the turbine 19 and worm gear 18 transmission usually has a self-locking characteristic, that is, it is difficult for the turbine 19 to drive the worm gear 18 in the reverse direction. In other words, when the motor 1 stops, the transmission system can automatically lock the position to prevent the shooting equipment from falling or changing its angle due to gravity or vibration, and can stably maintain the angle. The turbine 19 is mounted on the rotating shaft 17, and the rotation of the turbine 19 directly drives the rotating shaft 17 to rotate synchronously. The two ends of the rotating shaft 17 extend out of the second cavity 5 and pass through the round holes at the ends. One end of the two rotating brackets is fixedly connected to the two ends of the rotating shaft 17. Therefore, the rotation of the rotating shaft 17 drives the two rotating brackets to swing synchronously in an arc around the axis of the rotating shaft 17. The connecting plate 13 is fixedly connected to the other end of the two rotating brackets. The swinging motion of the rotating brackets is ultimately converted into the pitch angle change of the connecting plate 13 (and the shooting equipment mounted on it) around the axis of the rotating shaft 17 (i.e., the shooting equipment tilts up or down). When the external control system issues a stop signal (such as a power outage or a signal indicating that the target position has been reached), the motor 1 stops rotating. Thanks to the self-locking property of the worm gear 18 transmission of the turbine 19, the entire transmission system (from the worm gear 18 to the connecting plate 13) will immediately stop and be firmly locked at the current angular position.
[0040] In this embodiment, a compact, stable, and well-protected electric shooting angle adjustment device is constructed by the first cavity 2, the second cavity 5, the motor 1, the worm gear 18 and the turbine 19, the rotating shaft 17, the rotating bracket, and the connecting plate 13. The device utilizes the turbine 19 and the worm gear 18 to achieve low-speed, high-torque output and has a self-locking function, which can automatically and reliably lock the shooting angle when the drive stops. It is suitable for pitch angle adjustment scenarios that resist the influence of gravity and vibration (such as train applications).

The first end cover 3 is provided with a through hole, through which the cable of the motor 1 for connecting to the train passes out of the first cavity 2.
[0042] Please continue to refer to Figure 1 as well as Figure 2 As shown, in some embodiments, the shooting adjustment device further includes an aerial plug connector 4, wherein: the aerial plug connector 4 is installed on the first end cover 3 through the through hole; the cable of the motor 1 for connecting to the train is connected to the first end of the aerial plug; and the second end of the aerial plug connector 4 is used for connecting to the train. For example, Figure 1 As shown, the aircraft connector 4 can be installed on the first end cover 3 through the through hole, or the aircraft connector 4 can be installed on the first end cover 3 by screws at the position of the through hole.

[0046] Please continue to refer to Figure 1 as well as Figure 2 As shown, in some embodiments, the shooting adjustment device further includes a bearing sleeve 6, a bearing 8, a first sealing ring 7, a second sealing ring 11, a second end cap 9, and a third end cap 14.

The second end cap 9 and the third end cap 14 are respectively connected to the two ends of the second cavity 5 through the second sealing ring 11. The rotating bracket is fitted into the end of the rotating shaft 17 and fixedly connected by clamping rings (a first clamping ring 10 and a second clamping ring 15). After being fixedly connected by the clamping rings, the set bolts can be tightened to prevent the rotating bracket from slipping.
[0047] Please continue to refer to Figure 1 as well as Figure 2 As shown, in some embodiments, the shooting adjustment device further includes a fourth end cap 24, which is connected to the second side of the second cavity 5 via a sealing gasket (fourth sealing gasket 23).
[0048] In some embodiments, the shooting adjustment device is made of anodized aluminum alloy.
[0049] In some embodiments, the surface of the shooting adjustment device that comes into contact with the external environment is coated with an anti-corrosion nanocomposite ceramic coating.
[0050] In one exemplary embodiment, such as Figure 1 as well as Figure 2 As shown, a shooting adjustment device is also provided. The device is fixed to the roof or bottom of the vehicle with bolts, and the shooting equipment is connected and fixed to the connecting plate of the device with bolts. The device is designed with sealing gaskets at the mechanical connection points, combined with an IP67 protection-rated shell to prevent dust and rainwater intrusion; a hydrophobic and anti-fouling coating is applied to the lens surface of the shooting equipment to ensure that the pole number image remains clear over a long period of time. In the initial stage of use, the device presets a program to control the shooting angle, which is transmitted to the servo motor inside the device through the control system for matching. In the combined structure (shooting equipment + this device), during use, the pole number position archive information is transmitted to the servo motor through the control system. The servo motor receives the signal and rotates to a suitable angle, ultimately achieving adaptive adjustment of the shooting equipment's angle from -90° to +40° and stable data acquisition. The shooting adjustment device specifically includes: a (servo) motor 1 connected to a worm gear 18 via a key, and the motor body 1 connected to the second cavity 5 via screws. The second cavity 5 is connected to the first cavity 5 by screws, with the first sealing gasket 20 clamped in the middle. The turbine 19 is keyed to the rotating shaft 17 and then inserted into the second cavity 5. The bearing sleeve 6, bearing 8, and first sealing ring 7 are installed on the second cavity 5. The second end cover 9 and the third end cover 14 are connected to the second cavity 5 by screws after the second (radial) sealing ring 11 is installed. The first rotating bracket 12 and the second rotating bracket 16 are fitted into the end of the rotating shaft 17 and fixed by the first clamping ring 10 and the second clamping ring 15, respectively. The two rotating brackets are then tightened with set screws to prevent slippage. The fourth end cover 24 is connected to the second cavity 5 by screws, with the fourth sealing gasket 23 clamped in the middle. The first end cover 3 is connected to the second cavity 5 by screws, with the second sealing gasket 21 clamped in the middle. The aircraft connector 4 is connected to the motor 1 by screws. The hole for fixing the aircraft connector 4 is a blind hole, with the third sealing gasket 22 clamped in the middle. The connecting plate 13 is connected to the first rotating bracket 12 and the second rotating bracket 16 respectively by screws.
[0051] The enclosed structure obtained by combining the above-mentioned shooting adjustment device structure can be as follows: Figure 3 As shown.
[0052] The aforementioned shooting adjustment device can cover the shooting needs of multiple pole positions on the support structure, adapting to the distribution of pole numbers in different mountainous terrains. It solves the problem that traditional shooting equipment struggles to simultaneously cover the bottom, sides, and top of the support structure, and can adaptively adjust the shooting angle and be remotely controlled. The sealed design effectively prevents condensation or component failure inside the equipment due to large temperature differences in mountainous areas, and also prevents rainwater from easily penetrating the equipment. The anti-corrosion nano-composite ceramic coating on the outer shell prevents dust accumulation, avoiding dust entering the equipment and causing short circuits. This effectively reduces equipment maintenance costs and improves operational reliability.
[0053] The combined structure (shooting equipment + this device) is mounted on the top of the track inspection vehicle. GPS and LiDAR are used to locate the target support column. The control system compares and identifies the column number and archives the information, controlling the device's pitch angle to align with the column number. The shooting equipment then captures the column number. The main body of this device is made of 6061-T6 aluminum alloy, CNC machined and anodized, with a corrosion-resistant nano-composite ceramic coating to prevent dust accumulation. The sealing gasket is made of weather-resistant silicone (Shore hardness 60-70), effectively addressing the issue of reduced sealing performance due to temperature variations in mountainous areas. The device's connecting plate can accommodate shooting equipment of a certain size and allows for adaptive adjustment of the shooting equipment's angle from -90° to +40°, ensuring stable data acquisition. The combined structure meets general waterproof, dustproof, and rustproof requirements, with an operating temperature range of -25℃ to 100℃.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
