Description

Technical Field

[0001] This invention specifically relates to an endoscope window device, an installation method, and a shielding system. Background Technology

[0002] A hot chamber is a shielded space for radioactive operations, and its walls need to be equipped with viewing windows to allow staff to monitor the operation process. Currently, the viewing windows in hot chambers and other radioactive shielding rooms are mainly bolted to the inner wall of the chamber. If the viewing window needs repair or replacement due to decreased light transmittance or damage, staff must enter the hot chamber to perform the operation. However, due to space and environmental limitations within the hot chamber, repairing the viewing windows is difficult, dangerous, and time-consuming. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the aforementioned shortcomings in the prior art by providing an endoscopic window device. This device has a reasonable structural layout and can be disassembled and installed using automated equipment, thereby reducing operation time, difficulty, and danger. This invention also provides an installation method for the endoscopic window device and a shielding system.

[0004] This invention provides an endoscopic viewing window device, including a viewing window, a transmission mechanism, and a clamping mechanism. The clamping mechanism is arranged around the viewing window and connected to the transmission mechanism. When the transmission mechanism is driven by an input force, it drives the clamping mechanism to move, enabling the clamping mechanism to reach a set position to press the viewing window against the wall surface to be installed, thereby completing the installation and fixing of the viewing window. It also enables the clamping mechanism to move away from the set position to release the viewing window, thereby relieving the clamping force applied to the viewing window.

[0005] Furthermore, the transmission mechanism includes multiple transmission rods, one end of which serves as the input end of the transmission mechanism. The transmission rods are connected to achieve synchronous movement, so that when the input end is subjected to driving force, each transmission rod synchronously drives the pressing mechanism around the window to move.

[0006] Furthermore, the transmission rod is a lead screw, and the transmission mechanism also includes a commutator, a lead screw nut, and guide rails. Each transmission rod is arranged in parallel on each side of the viewing window. Adjacent transmission rods are connected at their joints by a commutator to achieve synchronous rotation. Multiple guide rails are provided, each parallel to the transmission rod. The clamping mechanism slides on the guide rails. The lead screw nut is connected to the clamping mechanism and is sleeved on the transmission rod. Driven by the rotation of the transmission rod, the clamping mechanism moves along the side of the viewing window to approach and move away from the set position.

[0007] Furthermore, the window is provided with a second pressing block on each side. The set position is the location where the second pressing block is provided on each side of the window. The pressing mechanism includes a plurality of first pressing blocks, each of which is arranged around the window. Driven by the transmission mechanism, it moves along the side of the window to approach and move away from the set position. The first pressing block and the second pressing block are provided with mutually adapted wedge surfaces so that when the first pressing block reaches the set position, the first pressing block applies downward pressure to the second pressing block through the wedge surface, thereby pressing the window tightly against the wall surface to be installed.

[0008] Furthermore, the device also includes a flange mounting plate, which is fixed to the wall surface to be installed. The transmission mechanism is connected to the flange mounting plate and drives the pressing mechanism to reach a set position to press the window onto the flange mounting plate, thereby completing the installation and fixing of the window.

[0009] Furthermore, the window is provided with a mounting part on both sides, and the flange mounting plate is provided with ear seats on both sides corresponding to the installation position of the window, which are used to support and position the window by supporting the mounting part.

[0010] Furthermore, the viewing window includes a window frame, a gasket, a pressure plate, and a viewing plate. The window frame is a frame structure formed by hollowing out both sides of a plate-like structure. The opening on the side away from the wall to be installed is smaller than the opening on the other side to form a stepped inner hole. The viewing plate is embedded in the inner hole of the window frame. One side is fixed by the stepped surface of the inner hole, and the other side is fixed by the pressure plate installed on the window frame. The gasket is placed between the viewing plate and the stepped surface, as well as between the viewing plate and the pressure plate.

[0011] The present invention also provides a method for installing an endoscope window device, for installing the aforementioned endoscope window device, the method specifically including the following steps:

[0012] Hoist the end-view window device to the wall surface where it will be installed;

[0013] Input driving force into the input end of the transmission mechanism until the clamping mechanism presses the window firmly onto the wall surface to be installed, thus completing the installation.

[0014] Furthermore, the step of inputting driving force to the input end of the transmission mechanism until the clamping mechanism presses the window onto the wall surface to be installed specifically includes: when inputting driving force to the input end of the transmission mechanism, determining whether the number of rotations of the input end has reached a set number of rotations, and stopping inputting driving force to the input end of the transmission mechanism after reaching the set number of rotations, wherein the set number of rotations is the number of rotations of the input end of the transmission mechanism when the clamping mechanism reaches the set position from the initial position.

[0015] The present invention also provides a shielding system, including a radiation shielding room and the aforementioned endoscope window device, wherein the radiation shielding room is used to house radiation operating equipment, and the endoscope window device is disposed on the wall of the radiation shielding room for viewing the interior of the radiation shielding room from the outside.

[0016] The endoscopic viewing window device of the present invention achieves the installation and fixation of the viewing window by pressing the viewing window against the wall surface to be installed by a clamping mechanism. Therefore, during the process of disassembling and replacing the viewing window, the clamping force applied to the viewing window by the clamping device can be removed. The entire installation and disassembly process is driven by the transmission mechanism.

[0017] Compared to the traditional bolt-based fastening method, this device only requires a single-point drive input at the input end of the transmission mechanism, eliminating the need for sequential fastening operations at multiple locations. This simplifies the operation and makes the positioning process easier, avoiding the decrease in positioning accuracy caused by reciprocating positioning. It also avoids the increased positioning difficulty and higher precision requirements caused by the small size of bolt fasteners. Furthermore, due to its simple positioning process, easy operation, and low precision requirements, this device can be installed and disassembled using remote operating equipment such as robotic arms, further reducing operation time and difficulty and completely eliminating any danger to operators.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the endoscopic viewing window device of this embodiment includes a viewing window 1, a transmission mechanism 2, and a pressing mechanism 3. The pressing mechanism 3 is arranged around the viewing window 1 and connected to the transmission mechanism 2. When the transmission mechanism 2 is driven by the input end, it drives the pressing mechanism 3 to move, so that the pressing mechanism 3 can reach a set position to press the viewing window 1 against the wall surface to be installed, thereby completing the installation and fixing of the viewing window 1. It can also move the pressing mechanism 3 away from the set position to release the viewing window 1, thereby relieving the pressing force applied to the viewing window 1.

[0031] In this embodiment, the window 1 is installed and fixed by pressing the window 1 against the wall surface to be installed by the pressing mechanism 3. Therefore, during the process of disassembling and replacing the window 1, the pressing force applied to the window by the pressing device 3 can be removed to disassemble and replace it. The entire installation and disassembly process is driven by the transmission mechanism 2.

[0032] Compared to the previous method of fastening with bolts, this device only requires a single-point drive input at the input end of the transmission mechanism 2, eliminating the need to perform fastening operations at multiple fastening positions sequentially. This simplifies the operation and makes the positioning process easier, avoiding the decrease in positioning accuracy caused by reciprocating movement. It also avoids the increased positioning difficulty and high precision requirements caused by the small size of bolt fasteners. Furthermore, due to the simplicity of the positioning process, ease of operation, and low precision requirements, this device can be used with remote operating equipment such as robotic arms for installation and disassembly operations, further reducing operation time and difficulty, and completely eliminating any danger to operators.

[0033] In this embodiment, as Figure 2 As shown, the transmission mechanism 2 includes multiple transmission rods 21, one end of which serves as the input end of the transmission mechanism 2. The transmission rods 21 are connected to achieve synchronous movement. When the input end is subjected to driving force, each transmission rod 21 synchronously drives the pressing mechanism 3 around the window 1 to move, thereby causing the pressing mechanism 3 around the window 1 to simultaneously complete the pressing action or the unloading action.

[0034] This synchronous connection method of each transmission rod 21 first simplifies the driving requirements, requiring only one drive input to complete all actions, and the drive device does not need to drive each transmission rod 21 sequentially to complete the transmission; secondly, it saves operation time, as the window 1 completes the pressing and unloading simultaneously in all directions at the same time; more importantly, the window 1 will not shift to one side due to the sequential pressing or unloading in each direction, ensuring uniform and reliable force distribution and reducing the difficulty of remote operation.

[0035] In this embodiment, the transmission rod 21 is a lead screw, specifically a trapezoidal lead screw with a self-locking function. The transmission mechanism 2 also includes a commutator 22, a lead screw nut 23, and a guide rail 24. Each transmission rod 21 is arranged in parallel on each side of the viewing window 1. The joints of adjacent transmission rods 21 are connected by the commutator 22 to achieve synchronous rotation. Multiple guide rails 24 are provided, and each guide rail 24 is arranged parallel to the transmission rod 21. The clamping mechanism 3 is slidably mounted on the guide rail 24. The lead screw nut 23 is connected to the clamping mechanism 3 and sleeved on the transmission rod 21. Under the rotation drive of the transmission rod 21, the clamping mechanism 3 is driven to move along the side of the viewing window 1 to approach and move away from the set position.

[0036] Specifically, a transmission rod 21 is installed on each of the four sides of the installation position of the viewing window 1. The two ends of the transmission rod 21 are rotatably mounted on the wall surface (flange mounting plate 4) to be installed via support bases 211. The mating ends of the transmission rods 21 above and to the left, left and below, and below and to the right of the viewing window 1 are connected by a reversing device 22. The right end of the transmission rod 21 above the viewing window 1 is connected to a reducer 26 via a coupling 25. The input end of the reducer 26 serves as the input end of the entire transmission mechanism 2. A clamping block 27 can be installed here to facilitate gripping input by devices such as robotic arms. The structure of the clamping block 27 is adapted to the gripping structure of the robotic arm. The guide rail 24 is located below the transmission rods 21.

[0037] When the remote control device inputs driving force to the input terminal, each transmission rod 21 rotates synchronously. At this time, the lead screw nut 23 will move accordingly. The lead screw nut 23 can convert the rotational motion of the lead screw into linear motion. Under the limit of the guide rail 24, the clamping mechanism 3 moves axially along the transmission rod 21 with the lead screw nut 23. At the same time, the clamping mechanism 3 is mounted on the guide rail 24 and is also used to counteract the reaction force generated during the clamping process of the viewing window 1.

[0038] In this embodiment, as Figure 3 and Figure 4 As shown, the window 1 is provided with a second pressing block 11 on each side. The set position is the location where the second pressing block 11 is set on each side of the window 1. The pressing mechanism 3 includes a plurality of first pressing blocks 31. Each first pressing block 31 is arranged around the window 1. Under the drive of the transmission mechanism 2, it moves along the side of the window 1 to approach and move away from the set position. The first pressing block 31 and the second pressing block 11 are provided with mutually adapted inclined wedge surfaces so that when the first pressing block 31 reaches the set position, the first pressing block 31 applies downward pressure to the second pressing block 11 through the inclined wedge surface, thereby pressing the window 1 tightly onto the wall surface to be installed.

[0039] Specifically, such as Figure 6 As shown, initially before clamping (i.e., before installation), the first pressure block 31 is located on one side of the second pressure block 11. The wedge surface on the second pressure block 11 is a slope that gradually decreases from near the first pressure block 31 to away from the first pressure block 31 (here, gradually decreasing means gradually moving away from the surface of the flange mounting plate 4); the wedge surface on the first pressure block 31 is a slope that gradually increases from near the second pressure block 11 to away from the second pressure block 11 (here, gradually increasing means gradually moving closer to the surface of the flange mounting plate 4). The inclination directions of the two wedge surfaces are consistent, and the wedge surface on the second pressure block 11 is not lower than the wedge surface on the first pressure block 31.

[0040] During installation, as the first pressure block 31 gradually approaches the set position, the wedge surfaces of the first pressure block 31 and the second pressure block 11 will gradually overlap. Due to the inclination of the wedge surface, the first pressure block 31 tends to move downward along the wedge surface. However, due to the limiting effect of the guide rail 24 and the transmission rod 21, the first pressure block 31 can only press the second pressure block 11 upward in the opposite direction, thereby pressing the entire window 1.

[0041] In this embodiment, as Figure 3 As shown, the first pressure block 31 includes a pressure block 311 and a pad block 312. The top of the pressure block 311 is provided with a sleeve portion for fitting and fixing the lead screw nut 23, and the bottom extends to one side with a wedge-shaped surface. The bottom surface is connected to the pad block 312, which is used to connect the guide rail 24.

[0042] In this embodiment, the device also includes a flange mounting plate 4, which is fixed to the wall surface to be installed. A transmission mechanism 2 is connected to the flange mounting plate 4. When the driving clamping mechanism 3 reaches a set position, it presses the viewing window 1 onto the flange mounting plate 4, thereby completing the installation and fixing of the viewing window 1. The transmission mechanism 2, clamping mechanism 3, viewing window 1, and lug 41 all use the flange mounting plate 4 as the installation reference. Therefore, the flange mounting plate 4 not only provides an installation surface for the entire device, improving its overall integrity, but also provides a clamping position for the viewing window 1, ensuring that the viewing window 1 can always adapt to installation regardless of the conditions of the wall surface to be installed.

[0043] In this embodiment, the viewing window 1 is provided with mounting parts 12 on both sides. On the flange mounting plate 4, ear seats 41 are provided on both sides corresponding to the installation position of the viewing window 1. The ear seats 41 are installed on the flange mounting plate 4 by bolts and are used to support and position the viewing window 1 by supporting the mounting parts 12. Before installation, the viewing window 1 is first hoisted to the installation position, and the ear seats 41 support the entire viewing window 1 to ensure that the viewing window 1 is stable in the installation position before pressing. When disassembling, after the pressing force is released, the viewing window 1 is supported by the ear seats 41 and still remains in the installation position, and can be lifted away by hoisting equipment.

[0044] In this embodiment, as Figure 5As shown, the viewing window 1 includes a window frame 13, a gasket 14, a pressure plate 15, and a transparent panel 16. In this embodiment, the transparent panel 16 is a glass plate; other transparent materials that meet the requirements can also be used in other embodiments. The window frame 13 is a frame-shaped structure formed by hollowing out both sides of a plate-like structure. The opening on the side away from the wall to be installed is smaller than the opening on the other side, forming a stepped inner hole. The transparent panel 16 is embedded in the inner hole of the window frame 13, fixed on one side by the stepped surface of the inner hole, and fixed on the other side by the pressure plate 15 installed on the window frame 13. The gasket 14 is placed between the transparent panel 16 and the stepped surface, and between the transparent panel 16 and the pressure plate 15. During installation, the side of the viewing window 1 with the pressure plate 15 is attached to the wall to be installed (flange mounting plate 4). The pressure plate 15 is connected to the window frame 13 by screws, forming a complete sealing structure with the gasket 14 and the glass plate itself.

[0045] A rubber ring 131 is provided on the surface of the window frame 13 near the wall to be installed. The rubber ring 131 is installed in a sealing groove opened on the window frame 13. Therefore, during the tightening process, the rubber ring 131 can completely seal the gap between the window 1 and the wall to be installed, ensuring the airtightness of the window 1. A lifting part 132 can also be provided on the top side of the window frame 13 to facilitate lifting and moving after being gripped by a robot arm.

[0046] The device of this embodiment can be used in the field of radioactive processing of nuclear materials and nuclear fuels. It provides a hot-chamber viewing window device that can be operated by a robotic arm and remotely replaced, suitable for hot chambers or equipment rooms in the field of nuclear material and nuclear fuel processing. When the device needs maintenance or replacement, there is no need for operators to enter the hot chamber; the viewing window can be replaced using a robotic arm outside the hot chamber.

[0047] Overall, this device mainly consists of a flange mounting plate 4, a transmission mechanism 2, a clamping mechanism 3, and a viewing window 1. The flange mounting plate 4 serves as the installation platform for the entire endoscope window device, ensuring the installation accuracy of each component of the endoscope window. The robotic arm can hold the clamping block 27 to transmit power to the endoscope window device. The transmission mechanism 2 consists of a reducer 27, a lead screw, a support seat 211, etc., and transmits power to the endoscope window device. The clamping mechanism 3 consists of a first clamping block 31, and the guide rail 24 provides power support for the entire clamping mechanism 3. The lead screw nut 23 carries the power transmitted by the lead screw, and the first clamping block 31 applies pressure to the viewing window 1. The viewing window 1 consists of a window frame 13, a glass plate, a gasket 14, a pressure plate 15, a rubber ring 131, etc. The viewing window 1 itself has sealing performance, and the sealing performance of the endoscope window device after installation can be ensured by the rubber ring 1 and the flange mounting plate 4. A lifting part 132 is provided on the upper edge of the window frame 13, and the robotic arm can hold the lifting part 132 to move the viewing window. The ear seat 41 is a supporting component of the viewing window 1.

[0048] When the robotic arm moves while gripping the clamping block 27, the four lead screws move simultaneously, thereby driving the clamping mechanism 3 to move. When the clamping mechanism 3 contacts the second pressure block 11 on the viewing window 1, the viewing window 1 begins to be clamped until the ideal clamping state is achieved. If the viewing window 1 needs to be replaced, the robotic arm gripping the clamping block 27 moves in the opposite direction, driving the clamping mechanism 3 to disengage from the viewing window 1. Then, the robotic arm grips the lifting part 132 on the viewing window 1, removes the viewing window 1, and replaces it with a new one.

[0049] This device enables remote replacement of the viewing window inside the hot chamber and allows for precise positioning via a controlled robotic arm. Furthermore, the use of a lead screw for force transmission provides self-locking properties during clamping and transmission. It also ensures the sealing requirements of the viewing window inside the hot chamber.

[0050] Example 2

[0051] The installation method of the endoscope window device in this embodiment can be used to install the endoscope window device in Embodiment 1. The method specifically includes the following steps:

[0052] Hoist the viewing window 1 to the wall surface where it will be installed;

[0053] Input driving force into the input end of transmission mechanism 2 until clamping mechanism 3 presses window 1 onto the wall surface to be installed, thus completing the installation.

[0054] Specifically, when window 1 needs to be replaced, the robotic arm grasps the new window 1 and places it onto the ear seat 41. The operator can observe the installation position and whether the window 1 is properly positioned using the robotic arm's built-in vision system. Driving force is input to the input end of the transmission mechanism 2 until the clamping mechanism 3 presses the window 1 firmly against the wall surface to be installed. This includes: when inputting driving force to the input end of the transmission mechanism 2, determining whether the number of rotations at the input end has reached the set number of rotations, and stopping the input of driving force after reaching the set number of rotations. The set number of rotations is the number of rotations at the input end of the transmission mechanism 2 when the clamping mechanism 3 moves from its initial position to the set position. More specifically, based on the pre-calculated compression of the viewing window seal ring, the wedge-shaped inclined clamping mechanism 3, and the lead of the lead screw, the number of rotations at the input end required to clamp the viewing window seal ring can be calculated. The robotic arm has a counting function; parameters are pre-set for the robotic arm according to the set number of rotations. When clamping is required, the calculated parameters are set for the robotic arm. After the robotic arm drives the input end to reach the specified number of revolutions, window 1 reaches the clamping state. Because the trapezoidal lead screw has a self-locking function, the robotic arm can be withdrawn from the input end after the clamping mechanism 3 reaches the specified position.

[0055] Example 3

[0056] The shielding system of this embodiment includes a radioactive shielding room and an endoscope window device as described in Embodiment 1. The radioactive shielding room is used to house radioactive operating equipment. The radioactive shielding room can be a shielded space such as a hot room. The endoscope window device is located on the wall of the radioactive shielding room and is used to observe the internal situation of the radioactive shielding room from the outside.

[0057] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
