Description

Technical Field

[0001] This utility model relates to the field of quick-installation technology for hot chamber cameras, and more specifically, to a quick-installation device for hot chamber cameras. Background Technology

[0002] In nuclear power engineering, the operation of a nuclear reactor generates spent fuel assemblies and components contaminated with radioactive materials. Hot cells, as important auxiliary facilities, are responsible for the maintenance and decommissioning of these components. The design of hot cells must meet stringent radiation protection requirements. They typically employ heavy-duty concrete exterior walls to shield against radiation, while the interior walls are lined with stainless steel for easy cleaning and decontamination. Lead glass or high-density liquid viewing windows are installed in the front wall, allowing personnel to operate remotely via robotic arms, avoiding radiation hazards. Simultaneously, hot cells are equipped with ventilation systems to maintain a certain negative pressure condition, and exhaust air is filtered to remove radioactive materials, ensuring environmental safety.

[0003] As monitoring equipment in hot chambers, cameras are easily susceptible to electrical component failure under high radiation doses, necessitating timely replacement for normal operation. Due to the unique environment of hot chambers, camera replacement can only be achieved using equipment such as robotic arms. Existing products and technologies have limitations: conventional camera installation typically requires screw tightening, and external cable connections usually use aviation connectors. Installing camera equipment with a robotic arm is extremely cumbersome; the connector plugging and unplugging process can be lengthy, and improper operation of the robotic arm can even lead to equipment damage. Solving the problem of easy camera installation and maintenance would significantly improve work efficiency. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a quick-mount device for a hot chamber camera to overcome the above-mentioned technical problems.

[0005] Therefore, the specific technical solution adopted in this utility model is as follows:

[0006] A quick-installation device for a hot chamber camera includes: a camera pan-tilt head, a quick-installation bracket, and a mounting bracket. The mounting bracket is fixedly connected to the hot chamber. The mounting bracket has a quick-installation bracket slot. The quick-installation bracket has a quick-installation guide post corresponding to the quick-installation bracket slot. The quick-installation bracket has a pan-tilt head slot. The camera pan-tilt head has a pan-tilt head guide post corresponding to the pan-tilt head slot. The camera pan-tilt head and the quick-installation bracket are respectively provided with robotic arm gripping parts. The camera pan-tilt head has a camera mounting cavity. The camera can be rotatably installed in the camera mounting cavity. The mounting bracket and the quick-installation bracket have positioning holes and are connected by positioning pins.

[0007] Furthermore, the camera pan-tilt unit includes a rotating component and a connecting component. The camera mounting cavity is located on the rotating component, and the pan-tilt unit quick-release guide column is located on the connecting component. The rotating component and the connecting component are horizontally rotatably connected to achieve horizontal and vertical rotation of the camera.

[0008] Furthermore, the rotating component is equipped with a gimbal robotic arm clamping part, and a lifting ring is connected above the gimbal robotic arm clamping part. This structural design allows for the selection of either clamping or hooking to disassemble the camera gimbal during actual operation, making it more convenient.

[0009] Furthermore, the bottom of the camera pan-tilt head is conical, and the quick-release guide post of the pan-tilt head is set on the side of the conical part of the camera pan-tilt head. A hollow conical pan-tilt head mounting part is provided above the quick-release bracket. The quick-release slot of the pan-tilt head is opened on the side wall of the pan-tilt head mounting part. The quick-release slot of the pan-tilt head is Y-shaped. The lower part of the pan-tilt head mounting part is provided with a quick-release bracket robotic arm clamping part. The outer surface of the quick-release bracket robotic arm clamping part is rough to increase the friction of the robotic arm clamping.

[0010] Furthermore, a first electrical connector male is installed at the bottom of the camera pan-tilt unit for connecting an external cable, and a first electrical connector female is placed inside the pan-tilt unit mounting section. The first electrical connector male and female are detachably connected. A second electrical connector female is connected below the quick-release bracket robotic arm clamping section, and the second electrical connector female is detachably connected to the second electrical connector male.

[0011] Furthermore, the quick-release bracket has a Y-shaped quick-release slot.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the structural design of this application, when it is necessary to replace the camera, the use of a robotic arm can realize the quick disassembly of all components of the hot chamber camera quick-installation device, which is simple and convenient.

[0014] 2. This application utilizes a robotic arm or hook to simply place the camera pan-tilt head roughly above the quick-release bracket. Because the Y-slot opening on the quick-release bracket is very large, as long as the cylindrical guide post on the camera pan-tilt head base enters the opening, the entire camera pan-tilt head can be placed downwards. Installation and electrical connector connection are completed by the guide and gravity, greatly facilitating camera replacement. If the electrical connector on the quick-release bracket fails due to excessive camera replacements or prolonged exposure, the robotic arm can be used to pull out the positioning pin and the second electrical connector male socket, allowing for quick removal and replacement from the mounting bracket.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the hot chamber environment of a nuclear power plant, personnel cannot enter to operate the monitoring equipment; therefore, cameras must be installed using a robotic arm. Since robotic arms struggle with complex operations, the camera installation design must be simple, easy to install, and easy to maintain. To address this issue, this application proposes a quick-installation device for hot chamber cameras, such as... Figure 1-5 As shown, it includes: a camera pan-tilt head 1, a quick-release bracket 2, and a mounting bracket 3. The camera pan-tilt head 1 is used to mount the camera and also enables the camera to rotate, allowing the camera to rotate within a certain range both horizontally and vertically, thereby increasing the camera's viewing angle.

[0023] Specifically, the camera pan-tilt unit 1 includes a rotating component and a connecting component. The rotating component can rotate horizontally relative to the connecting component. The camera mounting cavity 12 is opened on the rotating component. The pan-tilt quick-release guide column 11 is located on the connecting component. The rotating component is provided with a pan-tilt mechanical arm clamping part 13 for clamping the entire camera pan-tilt unit 1, thereby placing the camera in the desired position. For convenient operation, a lifting ring 14 is connected above the pan-tilt mechanical arm clamping part 13. The lifting ring 14 can be hooked by a hook to lift the camera pan-tilt unit 1 and move it, adding another way to move the camera. The camera pan-tilt unit 1 has a camera mounting cavity 12, and the camera can be rotatably installed in the camera mounting cavity 12. Based on the above structure, the horizontal and vertical rotation of the camera is realized.

[0024] The bottom of the camera pan-tilt head 1 is conical. The quick-release guide post 11 is set on the upper part of the conical side of the camera pan-tilt head 1. A hollow conical pan-tilt head mounting part 23 is provided above the quick-release bracket 2. The quick-release slot 22 is opened on the side wall of the pan-tilt head mounting part 23. The quick-release slot 22 is Y-shaped. The lower part of the pan-tilt head mounting part 23 is provided with a quick-release bracket robotic arm clamping part 24. The outer surface of the quick-release bracket robotic arm clamping part 24 is rough to increase the friction of the robotic arm clamping.

[0025] In order to realize the power supply of the device, the bottom of the camera pan-tilt head 1 is equipped with a first electrical connector male socket 4 for connecting external cables. The pan-tilt head mounting part 23 is used to house the first electrical connector female socket 5. The first electrical connector male socket 4 and the first electrical connector female socket 5 are detachably connected. The quick-release bracket robotic arm clamping part 24 is connected to a second electrical connector female socket 6. The second electrical connector female socket 6 is detachably connected to the second electrical connector male socket 7.

[0026] It should be noted that the mounting bracket 3 is fixedly connected to the hot chamber and can be fixed to the wall by screws or expansion bolts. The mounting bracket 3 is provided with a quick-installation bracket quick-installation slot 31, which is Y-shaped. The quick-installation bracket 2 is provided with a quick-installation guide post 21 corresponding to the quick-installation bracket quick-installation slot 31. The mounting bracket 3 and the quick-installation bracket 2 are provided with positioning holes and are connected by positioning pins 8.

[0027] When installing this hot chamber camera quick-release device, the mounting bracket 3 is fixed to the wall with screws or expansion bolts. Then, the robotic arm clamps the quick-release bracket's gripping part 24, and the quick-release guide post 21 of the quick-release bracket 2 is inserted downwards along the Y-shaped quick-release slot 31 on the mounting bracket 3. The robotic arm then inserts the positioning pin 8 into the positioning holes on both the mounting bracket 3 and the quick-release bracket 2 to secure them. Next, the camera pan-tilt head 1 is moved above the quick-release bracket 2 using the robotic arm or hook. The pan-tilt head quick-release guide post 11 on the camera pan-tilt head 1 is roughly aligned with the Y-shaped pan-tilt head quick-release slot 22 on the quick-release bracket 2. The camera pan-tilt head 1 is slowly lowered. After releasing the robotic arm or hook, under the influence of gravity, the first electrical connector male socket 4 on the camera pan-tilt head 1 is inserted into the first electrical connector female socket 5 along the pan-tilt head quick-release slot 22. Finally, the second electrical connector male socket 6 is inserted into the second electrical connector female socket 7 by controlling the robotic arm, completing the installation.

[0028] Advantages of this application: In the environment of a nuclear power plant's hot chamber, the radiation dose is typically very high. Cameras are easily damaged by gamma rays after a period of use. Electrical connectors and cables generally have a longer lifespan than cameras, so while cameras need to be replaced periodically, cables don't. This application uses a robotic arm or hook to simply place the camera pan-tilt head 1 roughly above the quick-release bracket 2. Because the Y-slot opening on the quick-release bracket 2 is very large, as long as the pan-tilt head guide post 11 enters the opening, the entire camera pan-tilt head 1 can be placed downwards. Installation and connection of the electrical connectors can be completed by guidance and gravity, greatly facilitating camera replacement. If the electrical connectors on the quick-release bracket 2 fail due to excessive camera replacements or prolonged radiation exposure, the robotic arm can be used to pull out the positioning pin 8 and the second electrical connector male socket 6, quickly removing them from the mounting bracket 2 for replacement.

[0029] In summary, this application provides a camera mounting device with a simple structure that is easy to install and maintain, which solves the limitations of using robotic arms and the difficulty of replacing camera equipment in radiation-resistant environments.

[0030] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
