Description

Technical Field

[0001] This invention specifically relates to the field of camera technology in high-radiation environments, and more specifically to a radiation-resistant pan-tilt camera that can be replaced remotely. Background Technology

[0002] In recent years, my country's nuclear industry has developed rapidly, forming a nuclear energy industrial chain that extends from uranium exploration and mining to nuclear fuel production and supply, nuclear power plant construction and operation, and finally, spent fuel processing. To achieve remote monitoring and operation of key equipment, areas, and processes in the nuclear industry, a certain number of cameras are required in high-radiation environments such as nuclear power plant reactor buildings, nuclear waste storage areas, and spent fuel processing workshops. These cameras typically need to be permanently mounted on walls and subjected to prolonged radiation doses, thus requiring high cumulative doses. Furthermore, due to the irradiated environment, personnel cannot easily access these areas, so camera replacement can only be performed remotely.

[0003] Currently, cameras used in high-radiation environments primarily employ optical waveguide cameras as image sensing devices. However, these cameras suffer from large processing circuitry, are extremely expensive, and are difficult to integrate into systems requiring multi-camera information display. Furthermore, the analog acquisition method of the optical waveguide camera itself results in black-and-white grayscale images with low resolution, making it difficult to clearly reflect the actual working conditions on-site. Therefore, it is necessary to develop a radiation-resistant pan-tilt camera that offers high cost-effectiveness, high image resolution, strong radiation resistance, and remote replaceability. Summary of the Invention

[0004] Therefore, the present invention proposes a radiation-resistant PTZ camera that can be replaced remotely to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radiation-resistant pan-tilt camera that can be replaced over a long distance, comprising:

[0006] A fixed bracket, wherein a wiring compartment is fixedly installed at one end of the fixed bracket;

[0007] A pitch and rotation gimbal compartment is mounted on the top surface of the wiring compartment;

[0008] And a periscope lens cabin, which is detachably installed on the pitch and rotation gimbal cabin. The periscope lens cabin includes a fixing block, a fixing clip, a lens cabin body, and a lens module. A fixing clip is fixedly installed at the center of the left and right side walls of the lens cabin body. A fixing block is fixedly installed at the top of the left and right side walls of the lens cabin body. A hook is connected between two fixing blocks, and an auxiliary light source is fixedly installed on the front of each fixing block.

[0009] A lens viewing window is sealed and installed at the window on the front of the lens housing. A top shield, a middle shield, and a bottom shield are fixedly installed on the inner wall of the lens housing by bolts, and a lens module is installed between the top shield, the middle shield, and the bottom shield.

[0010] Furthermore, as a preferred embodiment, the lens module includes a camera core, an adjustment support base, and a reflective lens. The camera core is fixedly installed at the bottom of the adjustment support base, and the reflective lens is fixedly installed at the top of the adjustment support base, with the reflective lens and the camera core forming a 45° angle.

[0011] Furthermore, as a preferred embodiment, the pitch and rotation gimbal cabin consists of a gimbal cabin body and a quick-release assembly, wherein the gimbal cabin body is configured with a "U"-shaped structure, and the quick-release assembly is installed on the inner side of the gimbal cabin body.

[0012] Furthermore, as a preferred embodiment, the gimbal housing is provided with a pitch motion component and a rotation motion component, wherein the rotation motion component can drive the gimbal housing to rotate along its centerline, and the pitch motion component can drive the quick-release component to adjust the pitch state.

The rotary motor is fixedly installed inside the gimbal housing, the rotary motor shield is located on the outside of the rotary motor, and the rotary drive wheel is driven to the drive end of the rotary motor.

[0014] One end of the rotating spindle is fixedly connected to the top surface of the wiring compartment, and the other end of the rotating spindle passes through the gimbal compartment and is fixedly connected to the rotating driven wheel. The rotating driven wheel and the rotating drive wheel are connected by a rotating conveyor belt.

[0015] Furthermore, as a preferred embodiment, the pitch motion assembly includes a pitch motor, a pitch motor shield, a pitch drive wheel, and a pitch shaft. The pitch motor is fixedly installed inside the gimbal housing, the pitch motor shield is located on the outside of the pitch motor, and the pitch drive wheel is driven to the drive end of the pitch motor.

[0016] One end of the pitch axis is fixedly connected to the quick-release assembly, and the other end of the pitch axis is inserted into the gimbal housing and fixedly connected to the pitch driven wheel. The pitch driven wheel and the pitch drive wheel are connected by a pitch conveyor belt.

[0017] Furthermore, preferably, the quick-release assembly includes a horizontal connecting rod, a pull rod, and two symmetrically arranged fixing components. Both ends of the horizontal connecting rod are fixedly connected to fixing components, and each fixing component has a pull rod fixing member fixedly installed at its end away from the horizontal connecting rod.

[0018] The fixing assembly includes an outer fixing plate, a fixing block, an inner fixing plate, bolt columns, and a slider. The fixing block is configured with a "V" shape. An inner fixing plate and an outer fixing plate are fixedly installed on the inner and outer sides of the fixing block, respectively. Two bolt columns connect the inner and outer fixing plates. A slider is provided at the bottom of the fixing block. Two sliding grooves are provided through the slider. A corresponding bolt column is inserted into each sliding groove. The end of a pin is bolted to the right inner side wall of the slider. The end of the pin can be inserted into the inner side of the fixing block.

[0019] Both ends of the pull rod are rotatably connected to one end of the pull rod guide block, and the other end of the pull rod guide block passes through the pull rod fixing component and is fixedly connected to the slider, so that the pull rod can drive the slider to slide in the horizontal direction, thereby enabling the needle tip of the insertion pin to be inserted into the fixing block on the lens housing.

[0020] Furthermore, as a preferred embodiment, the wiring compartment includes a wiring compartment fixing plate, a wiring compartment body, and quick-release connectors. The wiring compartment body is fixed to the fixing bracket, the wiring compartment fixing plate is fixedly installed on the top surface of the wiring compartment body, and two quick-release connectors are fixedly installed on the side wall of the wiring compartment body. One of the quick-release connectors is connected to a cable connector located on the lens compartment body using a connecting cable.

[0021] Furthermore, as a preferred embodiment, the quick-release connector includes a quick-release connector female, a quick-release connector male, and a guide post. The quick-release connector female is fixed on the wiring compartment, and the female end of the quick-release connector female is matched and plugged into the male end of the quick-release connector male.

[0022] Furthermore, as a preferred embodiment, a guide groove is provided on the female end sidewall of the quick-release connector, and a guide post is fixed on the male end sidewall of the quick-release connector, the guide post being able to slide within the guide groove.

[0023] The present invention employs the above technology and has the following beneficial effects compared with existing technologies:

[0024] 1. The camera module uses a high-definition image sensor, which greatly improves the camera's image resolution and can clearly reflect the actual working conditions on site.

[0025] 2. To improve the radiation resistance of the high-definition image sensor, a three-layer shielding structure and a periscope-style reflective lens module are adopted to prevent direct damage to the camera core from radiation. The three-layer shielding structure can also adjust the center of gravity of the lens housing to ensure the stability of the lens housing's pitch movement.

[0026] 3. To improve the lifespan of the equipment, a remote replacement function has been added. Since the camera is heavier after the shielding is added, the load capacity of the robotic arm cannot complete the overall replacement. At the same time, considering that the camera core is the most vulnerable component, quick-release components and quick-release connectors have been designed to enable the robotic arm to independently replace the periscope lens compartment and realize the periodic replacement of the camera core. In addition, the function of replacing the pitch and rotation gimbal compartment and the wiring compartment has been reserved, which greatly improves the lifespan of the equipment.
