[0002] In the perimeter security system of a nuclear power plant, perimeter security is a core component in ensuring the safe operation of nuclear facilities. The water pool within the perimeter is a special and critical area that requires real-time monitoring. The current practice is to install cameras inside the pool and securely fix them to the pool walls using brackets. This fixed installation method can provide staff with relatively stable monitoring images. However, due to the fixed nature of the brackets, when a camera malfunctions or reaches the end of its service life and needs to be replaced, staff must first drain the pool water before they can perform maintenance or replacement operations. Draining operations are not only time-consuming but also require additional manpower and resources, increasing maintenance costs. Summary of the Invention

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] This application proposes an underwater camera lifting device, such as... Figures 1 to 5 As shown, the system includes: a camera 100, a guide rail 200, a bracket 300, and a traction member 320; the guide rail 200 is provided with a fixing part 210, which is suitable for fixing the guide rail 200 to the wall of the pool, and the guide rail 200 is perpendicular to the bottom of the pool; the bracket 300 is located on the side of the guide rail 200 away from the fixing part 210, and the bracket 300 can reciprocate along the length of the guide rail 200; the camera 100 is located on the side of the bracket 300 away from the guide rail 200; wherein; the bracket 300 is provided with a traction ring 310, one end of the traction member 320 is fixedly connected to the traction ring 310, and the other end of the traction member 320 extends to the top of the pool.

[0024] It should be noted that one end of the fixing part 210 is fixedly connected to the guide rail 200, and the other end of the fixing part 210 is fixedly connected to the wall of the pool. The fixing part 210 provides a stable installation base for the entire device, preventing the guide rail 200 from shaking or shifting due to the buoyancy and impact of the water, thus ensuring the stability of the overall device structure. The guide rail 200 provides a clear movement path for the bracket 300, ensuring that the bracket 300 and the camera 100 can move smoothly along a predetermined direction. The length of the guide rail 200 can be designed according to the depth of the pool, without the need to redesign the overall structure for different pools. The bracket 300 provides an installation position for the camera 100, ensuring that the camera 100... The camera 100 will not shake or fall during movement. The bracket 300 reciprocates along the length of the guide rail 200, thereby moving the camera 100 on the bracket 300. The traction ring 310 is fixedly installed on the top of the bracket 300 near the guide rail 200. The traction ring 310 is fixedly connected to one end of the traction member 320. The other end of the traction member 320 extends to the top of the pool. The traction ring 310 is used to convert the upward traction force or downward release force applied by the traction member 320 into the force of the bracket 300 sliding axially along the guide rail 200. This allows the staff above the pool to raise the bracket 300 and the camera 100 to the water surface for maintenance or lower them to the underwater working position for continued monitoring by raising and lowering the traction member 320.

[0025] When maintenance or replacement of camera 100 is required, the staff pulls the traction component 320, which drives the bracket 300 to move along the length of the guide rail 200 toward the water surface via the traction ring 310, thereby lifting camera 100 from the water to above the pool. At this time, the staff can easily perform repair, replacement or other maintenance operations on camera 100. After the maintenance operation is completed, the staff releases the traction component 320, allowing the bracket 300 to slide downward along the length of the guide rail 200 under the action of gravity, thereby putting camera 100 back into the pool.

[0026] This application, by setting up a guide rail 200, a bracket 300, and a traction component 320, allows the guide rail 200, bracket 300, and traction component 320 to work together, enabling the bracket 300 to reciprocate along the length of the guide rail 200. When the camera 100 malfunctions and needs repair or reaches the end of its service life and needs replacement, the staff only needs to pull the bracket 300 with the traction component 320 to lift the camera 100 along the guide rail 200 to the top of the pool, making maintenance or replacement easy. This avoids the extra manpower and resources required for drainage, significantly reducing maintenance costs and improving work efficiency. At the same time, the device structure of this application is simple and easy to install and maintain.

[0027] In one possible implementation, the traction component 320 can be made of a high-strength rope, such as a steel wire rope or a synthetic fiber rope, to ensure that it can withstand the weight of the camera 100 and the support 300 during the lifting and lowering of the camera 100, while also having good flexibility for easy operation. Scale markings can also be set on the traction component 320 so that the operator can accurately control the depth of the camera 100 below the water tank according to the scale markings.

[0028] In one possible implementation, an angle adjustment device 400 is also included; the main body of the bracket 300 has an L-shaped structure, the angle adjustment device 400 is installed in the opening of the bracket 300, and the camera 100 is mounted on the adjustment device.

[0029] It should be noted that the bracket 300 includes mutually perpendicular vertical connecting plates and horizontal mounting plates. The vertical connecting plates are slidably connected to the guide rail 200. The camera 100 is mounted on the horizontal mounting plate via an angle adjustment device 400. The adjustable mounting angle of the camera 100 on the bracket 300 is achieved through the angle adjustment device 400. The adjustable mounting angle of the camera 100 on the bracket 300 means that the angle between the optical axis of the camera 100 lens and the plane of the horizontal mounting plate (i.e., the pitch angle of the camera 100) is adjustable. By operating the angle adjustment device 400, the operator can make the lens of the camera 100 face the bottom of the pool or the surface of the water, thereby adjusting the area monitored by the camera 100 and ensuring that the lens is always pointed at the target area to be monitored.

[0030] In one possible implementation, such as Figure 3 As shown, the angle adjustment device 400 includes: a fixed plate 410 and an adjusting member 420; a first hinge member 430 and a second hinge member 440 are provided in the opening of the bracket 300; one end of the fixed plate 410 is hinged to the first hinge member 430, and a third hinge member 450 is provided at the end of the fixed plate 410 away from the first hinge member 430; one end of the adjusting member 420 is hinged to the third hinge member 450, and the other end of the adjusting member 420 is hinged to the second hinge member 440; the camera 100 is mounted on the fixed plate 410.

[0031] It should be noted that the first hinge 430 and the second hinge 440 are respectively mounted on the horizontal mounting plate of the bracket 300. The main body of the fixing plate 410 is a rectangular plate structure. The fixing plate 410 is suitable for providing a mounting base for the camera 100. One end of the fixing plate 410 is hinged to the horizontal mounting plate of the bracket 300 through the first hinge 430, so that the fixing plate 410 rotates about the first hinge 430 as an axis, thereby driving the camera 100 on the fixing plate 410 to rotate and change the pitch angle of the camera 100. The two ends of the adjusting member 420 are respectively connected to the third hinge 450 on the fixing plate 410 and the second hinge 440 on the horizontal mounting plate of the bracket 300. When the adjusting member 420 extends or retracts, the two ends of the adjusting member 420 rotate about the second hinge 440 and the third hinge 450 as axes, thereby pushing the fixing plate 410 to rotate around the first hinge 430, thereby realizing the adjustment of the pitch angle of the camera 100.

[0032] Furthermore, the adjusting element 420 is a turnbuckle as used in the prior art.

[0033] In one possible implementation, the first hinge member 430 includes a first hinge ear 431, a second hinge ear, and a first pivot shaft disposed opposite to each other. The first hinge ear 431 is disposed opposite to each other on the horizontal mounting plate of the bracket 300 and is located on the same side of the horizontal mounting plate. The corresponding second hinge ear is disposed on the fixed plate 410 and is disposed opposite to each other between the two first hinge ears 431. The first pivot shaft passes through the two first hinge ears 431 and the second hinge ear. The second hinge ear cooperates with the first hinge ear 431 and passes through the first pivot shaft to form a complete hinge structure, thereby enabling the fixed plate 410 to rotate stably around the first pivot shaft.

[0034] Furthermore, both the second hinge member 440 and the third hinge member 450 include two third hinge ears 441 and a second pivot. The two third hinge ears 441 are disposed opposite to each other on the horizontal mounting plate of the bracket 300 and are located on the same side of the horizontal mounting plate. The third hinge ears 441 are disposed opposite to the first hinge ears 431. The ends of the adjusting member 420 are disposed opposite to each other between the two third hinge ears 441. The third pivot is disposed through the third hinge ears 441 and the ends of the adjusting member 420. The third hinge ears 441 and the ends of the adjusting member 420 cooperate with each other and are disposed through the second pivot to form a complete hinge structure. This allows the two ends of the adjusting member 420 to rotate about the second hinge member 440 and the third hinge member 450 respectively, thereby pushing the fixed plate 410 to rotate around the first hinge member 430.

[0035] In one possible implementation, a slider 330 is also included; the slider 330 is disposed on the side of the bracket 300 adjacent to the guide rail 200; a groove 201 is provided on the guide rail 200 and the groove 201 extends along the length of the guide rail 200; the slider 330 is slidably disposed in the groove 201 on the side away from the bracket 300.

[0036] It should be noted that the slide groove 201 has a T-shaped groove structure in cross section. The slide groove 201 provides precise guidance for the reciprocating motion of the support 300, ensuring that it can maintain an accurate path and trajectory during the movement. Correspondingly, the slider 330 has a T-shaped structure in cross section. The slider 330 includes a sliding part and a connecting part that are perpendicular to each other. One end of the connecting part is fixedly connected to the vertical connecting plate of the support 300, and the end of the connecting part away from the vertical connecting plate is fixedly connected to the sliding part. The sliding part is slidably disposed in the slide groove 201.

[0037] In one possible implementation, a mounting bracket 500 is also included; the mounting bracket 500 is mounted on the mounting plate 410 by means of pins 520, and the camera 100 is mounted on the mounting bracket 500.

[0038] It should be noted that the main body of the fixing bracket 500 has a U-shaped structure. The fixing bracket 500 is set on the fixing plate 410, and the opening of the fixing bracket 500 faces the side away from the fixing plate 410. The end of the fixing bracket 500 near the fixing plate 410 has two or more mounting holes 510, which are arranged in a circle. Correspondingly, the fixing plate 410 has positioning holes. By rotating the fixing bracket 500 to a suitable position, the pin 520 passes through the mounting hole 510 and the positioning hole in sequence to fix the relative position of the fixing bracket 500 and the fixing plate 410.

[0039] In one possible implementation, a rotating component 600 is also included; the rotating component 600 is disposed on the fixed plate 410 and is located between the fixed plate 410 and the fixed frame 500; the rotating component 600 enables the camera 100 to rotate in the horizontal direction, and combined with the original pitch angle adjustment, enables the camera 100 to monitor a larger area, improving the comprehensiveness of the monitoring.

[0040] In one possible implementation, the rotating assembly 600 includes a fixed base and a rotating shaft; the fixed base is disposed on the fixed plate 410, one end of the rotating shaft is rotatably disposed on the fixed base, and the other end of the rotating shaft is fixedly connected to the fixed frame 500.

[0041] It should be noted that the mounting base is fixedly installed on the mounting plate 410 by bolts. The mounting base is suitable for providing a stable rotation reference for the rotating shaft, ensuring that the rotating shaft can only rotate around its own axis and avoiding rotational deviation caused by the shaking of the mounting base. One end of the rotating shaft is rotatably mounted on the mounting base, and the other end of the rotating shaft is fixedly connected to the end of the mounting bracket 500 facing the mounting plate 410. By driving the rotating shaft to rotate, the mounting bracket 500 and the camera 100 on the mounting bracket 500 are simultaneously driven to rotate horizontally, thereby realizing the horizontal adjustment of the camera 100's viewing angle.

[0042] In one possible implementation, a fall arrestor 710 is also included. The fall arrestor 710 is fixedly installed at the bottom of the guide rail 200, and the length direction of the fall arrestor 710 is perpendicular to the length direction of the guide rail 200. It should be noted that the fall arrestor 710 is rigidly fixed to the bottom of the rail, and its length direction is perpendicular to the guide rail 200, forming a lateral limit stop. When the bracket 300 detaches from the end of the guide rail 200 due to a malfunction, the vertical surface of the fall arrestor 710 will directly prevent the bracket 300 from falling, thereby achieving mechanical hard limiting and preventing the bracket 300 and the camera 100 from falling directly into the bottom of the pool and causing damage.

[0043] Furthermore, one end of the fall arrestor 710 is fixedly connected to the pool wall 730, further enhancing the stable connection between the guide rail 200 and the pool wall 730.

[0044] In one possible implementation, there are two or more fixing parts 210; the two or more fixing parts 210 are spaced apart along the length of the guide rail 200; the multiple spaced fixing parts 210 can evenly distribute the weight borne by the guide rail 200 and the load generated by the water flow impact onto the pool wall 730, effectively preventing the fixing parts 210 from falling off the pool wall 730 due to excessive local pressure, and ensuring that the guide rail 200 is always firmly fixed to the wall.

[0045] Furthermore, two or more fixing parts 210 are arranged at equal intervals.

[0046] In one possible implementation, the ends of the fixing part 210 and the anti-falling component 710 facing the pool wall 730 are both provided with mounting plates 211; the main body of the mounting plate 211 is a rectangular plate structure, and holes are opened at the four corners of the mounting plate 211. Bolts pass through the mounting plate 211 and are fixedly connected to the pool wall. The rectangular plate structure of the mounting plate 211 increases the contact area between the fixing part 210, the anti-falling component 710 and the pool wall 730, avoiding fixation failure due to excessive local pressure, thereby ensuring that the fixing part 210 and the anti-falling component 710 are firmly attached to the pool wall 730.

[0047] In one possible implementation, the guide rail 200 is provided with a rib 720, and the rib 720 is provided on the same side as the fixing part 210. The rib 720 increases the moment of inertia of the guide rail 200 section, which prevents the guide rail 200 from bending or twisting under stress and extends the service life of the guide rail 200.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
