[0044] Figure 1 The invention shows a nuclear power detector retractable storage mechanism 10 in some embodiments of the present invention, which includes a lifting assembly 1 and a retractable assembly 2. The lifting assembly 2 is arranged in the reactor core pool, and the lifting assembly 1 is driven and connected to the retractable assembly 2. It can be understood that the lifting assembly 1 is used to drive the retractable assembly 2 to move in the reactor core pool. The retractable assembly 2 is used to coil and store the detector.

[0045] like Figure 2 and Figure 3 As shown, the lifting assembly 1 includes a lifting track 11 and a lifting module 12 slidably disposed on the lifting track 11 .

[0046] It can be understood that the lifting track 11 is used to guide the lifting module 12 to move, and the lifting module 12 is used to drive the shrinking component 2 to move.

[0047] like Figures 2 to 7As shown, the shrinking assembly 2 includes a coiling module 21, a sliding module 22, a clamping module 23 and a reciprocating module 24. The coiling module 21 is slidably set on the lifting module 12, the sliding module 22 is driven and connected to the coiling module 21, the clamping module 23 is slidably set on the lifting module 12, and the reciprocating module 24 is driven and connected to the clamping module 23.

[0048] The sliding module 22 is used to drive the coiling module 21 to move between the coiling position 21a and the releasing position 21b. The coiling module 21 rotates at the coiling position 21a to coil the detector. The coiling module 21 releases the detector after moving to the releasing position 21b.

[0049] The detector is clamped by the clamping module 23 and then led to the coiling position 21a. The reciprocating module 24 is used to drive the clamping module 23 to move on the lifting module 12, thereby adjusting the relative position of the clamping module 23 and the coiling position 21a, so that the detector can be wound on the coiling module 21 circle by circle.

[0050] It can be understood that the coiling module 21 is slidably installed on the lifting module 12, and can be switched between the coiling position 21a and the release position 21b under the action of the sliding module 22. When located at the coiling position 21a, the coiling module 21 rotates to coil the detector; and after moving to the release position 21b, the coiled detector can be released. The sliding module 22 drives the coiling module 21 to move between the coiling position 21a and the release position 21b. The clamping module 23 is slidably set on the lifting module 12, responsible for clamping the detector and guiding it to the coiling position 21a. The reciprocating module 24 drives the clamping module 23 to move on the lifting module 12, thereby adjusting the relative position of the clamping module 23 and the coiling position 21a, ensuring that the detector can be wound around the coiling module 21 circle by circle.

[0051] It should be noted that, during the working process, the clamping module 23 is first used to fix and guide the detector to the coiling position 21a. Then, through the operation of the sliding module 22, the coiling module 21 reaches the coiling position 21a and starts to rotate. At the same time, the reciprocating module 24 adjusts the position of the clamping module 23 so that the detector can be evenly wound on the coiling module 21. After the coiling is completed, the sliding module 22 moves the coiling module 21 to the release position 21b for subsequent processing or storage.

[0052] like Figures 4 to 7As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the sliding module 22 includes a sliding drive member 221, a sliding rail 222 and a sliding seat 223, the sliding drive member 221 and the sliding rail 222 are respectively arranged on the lifting module 12, the sliding seat 223 is slidably arranged on the sliding rail 222, and the sliding drive member 221 is drivingly connected to the sliding seat 223; the winding module 21 is arranged on the sliding seat 223, and the winding module 21 is driven by the sliding seat 223 to move between the winding position 21a and the release position 21b.

[0053] It can be understood that the coiling module 21 is arranged on the sliding seat 223. Therefore, when the sliding drive 221 is operated, it can drive the sliding seat 223 and the coiling module 21 thereon to move along the sliding track 222, thereby realizing the conversion of the coiling module 21 between the coiling position 21a and the release position 21b.

[0054] The sliding drive 221 and the sliding track 222 work together to ensure the smooth movement of the sliding seat 223. The sliding drive 221 can be a motor or other forms of power source, which can control the moving distance and speed of the sliding seat 223 to meet the needs of detectors of different lengths and types. The sliding seat 223 not only serves as a carrier of the coiling module 21, but also ensures the stability and accuracy of the coiling module 21 during movement through its cooperation with the sliding track 222. As a result, the coiling module 21 can smoothly switch between the coiling position 21a and the release position 21b, thereby improving the response speed and work efficiency of the entire device.

[0055] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the coiling module 21 includes a coiling seat 211, a coiling sealing cylinder 212, a coiling motor 213, a coiling transmission gear set 214 and a coiling shaft 215, the coiling seat 211 is arranged on the sliding seat 223, the coiling sealing cylinder 212 is arranged on the coiling seat 211, the coiling motor 213 is arranged in the coiling sealing cylinder 212, the coiling motor 213 is drivingly connected to the coiling transmission gear set 214, and the coiling transmission gear set 214 is drivingly connected to the coiling shaft 215;

[0056] When the sliding seat 223 slides, it can drive the reel shaft 215 to move between the reeling position 21a and the releasing position 21b. The reeling motor 213 drives the reel shaft 215 to rotate through the reeling transmission gear set 214. When the reel shaft 215 rotates, it reels around the detector.

[0057] It can be understood that the reel seat 211 is used to provide basic support for the entire reel module 21. The reel sealing cylinder 212 is used to protect the internal components from the external environment and provide a closed working space. The reel motor 213 is the power source for driving the reel shaft 215 to rotate. It is connected to the external control system by electrical connection or mechanical connection, and starts or stops after receiving instructions. The reel transmission gear set 214 is responsible for transmitting power and adjusting the speed and torque. The gear set setting ensures efficient energy conversion from the motor to the shaft; further, the reel transmission gear set 214 can be configured to include a plurality of transmission gears, and power transmission is achieved through the meshing of gears. When the reel motor 213 is running, the reel shaft 215 is driven to rotate through the reel transmission gear set 214, so that the detector can be evenly wound around the reel shaft 215.

[0058] It should be noted that, during the working process, the detector is first fixed and guided to the coiling position 21a using the clamping module 23. Then, the sliding drive 221 in the sliding module 22 drives the sliding seat 223 together with the coiling module 21 thereon to move to the coiling position 21a. At this time, the coiling motor 213 starts and drives the coiling shaft 215 to rotate through the coiling transmission gear set 214 to start coiling the detector. At the same time, the reciprocating module 24 adjusts the position of the clamping module 23 to ensure that the detector can be evenly coiled on the coiling shaft 215. After the coiling is completed, the sliding drive 221 moves again to move the sliding seat 223 together with the coiling module 21 to the release position 21b for subsequent processing or storage.

[0059] like Figure 6 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the coil module 21 further includes a first side plate 216, a push-out guide rail 217, a second side plate 218, a push-out drive member 219 and an auxiliary roller 2100;

[0060] The first side plate 216 and the ejection guide rail 217 are respectively arranged on the lifting module 12, the second side plate 218 is slidably arranged on the ejection guide rail 217, the ejection driving member 219 is drivingly connected to the second side plate 218, one end of the auxiliary roller 2100 is connected to the second side plate 218, and the second side plate 218 is driven by the ejection driving member 219 to move toward or away from the first side plate 216, so that the other end of the auxiliary roller 2100 can be detachably inserted into the first side plate 216, and the auxiliary roller 2100 and the reel shaft 215 are respectively supported on the detector from opposite sides.

[0061] It can be understood that the first side plate 216 serves as a docking point at one end of the auxiliary roller 2100. The push-out guide rail 217 provides a sliding path for the second side plate 218. The second side plate 218 can move along the guide rail under the action of the push-out drive 219. The push-out drive 219 drives the second side plate 218 to move in a direction close to or away from the first side plate 216. The auxiliary roller 2100 can be inserted into or pulled out of the first side plate 216 when the second side plate 218 moves. After the auxiliary roller 2100 is inserted into the first side plate 216, the auxiliary roller 2100 and the winding shaft 215 are respectively supported on the detector from opposite sides to ensure that the detector remains stable during the winding process and prevent it from being offset or unevenly wound during winding.

[0062] It should be noted that when the detector needs to be coiled, the detector is first guided to the coiling position 21a by the clamping module 23. Then, the sliding drive 221 in the sliding module 22 drives the sliding seat 223 together with the coiling module 21 thereon to move to the coiling position 21a. At the same time, the push-out drive 219 is started, pushing the second side plate 218 to slide along the push-out guide rail 217, so that one end of the auxiliary roller 2100 is inserted into the first side plate 216, thereby forming a stable clamping structure between the auxiliary roller 2100 and the coiling shaft 215. At this time, the coiling motor 213 is started and drives the coiling shaft 215 to rotate through the coiling transmission gear set 214, and the detector begins to be coiled. The presence of the auxiliary roller 2100 ensures the stability of the detector during the coiling process and avoids unnecessary distortion or damage.

[0063] After the coiling is completed, the sliding drive 221 moves again to move the sliding seat 223 together with the coiling module 21 to the release position 21b. At this time, the push-out drive 219 operates in the reverse direction to retract the second side plate 218, and the auxiliary roller 2100 is separated from the first side plate 216, so that the auxiliary roller 2100 is separated from the detector behind the coiling, and the detector separation of the coiling is completed.

[0064] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the clamping module 23 includes a clamping seat 231, a fixed clamping roller 232, a fixed guide cylinder 233, a clamping cylinder 234, a floating clamping roller 235, a floating guide cylinder 236 and a floating connector 237;

[0065] The reciprocating module 24 is driven and connected to the clamping seat 231, the fixed clamping roller 232 and the fixed guide cylinder 233 are both arranged on the clamping seat 231, the clamping cylinder 234 is arranged on the clamping seat 231 and is driven and connected to the floating connection member 237, the floating clamping roller 235 and the floating guide cylinder 236 are both arranged on the floating connection member 237, the clamping cylinder 234 drives the floating connection member 237 to move, so that the floating clamping roller 235 moves toward or away from the fixed clamping roller 232, and the floating guide cylinder 236 moves toward or away from the fixed guide cylinder 233;

[0066] When the floating guide cylinder 236 abuts against the fixed guide cylinder 233, the floating guide cylinder 236 and the fixed guide cylinder 233 jointly define a cylindrical space. The detector passes through the cylindrical space and is clamped between the fixed clamping roller 232 and the floating clamping roller 235, so that the detector is wound at different positions on the winding module 21 when the clamping seat 231 moves.

[0067] It can be understood that the clamping seat 231 is used to provide basic support for the entire clamping module 23. The clamping seat 231 is fixedly arranged on the lifting module 12, and the reciprocating module 24 is driven and connected to the clamping seat 231 to realize the movement of the clamping seat 231 on the lifting module 12. The fixed clamping roller 232 is used to cooperate with the floating clamping roller 235 to clamp the detector. The fixed guide cylinder 233 and the floating guide cylinder 236 jointly define a cylindrical space for the detector to pass through and guide the detector; wherein, the detector itself has a certain flexibility, which is easy to produce after being inserted into the core for a long time.

[0068] The clamping cylinder 234 provides power to move the floating clamping roller 235 toward or away from the fixed clamping roller 232. The floating clamping roller 235 can move under the action of the clamping cylinder 234 and work in conjunction with the fixed clamping roller 232 to ensure that the detector can be stably clamped and wound when it is guided to the winding position 21a. The floating guide cylinder 236 is also arranged on the floating connecting member 237. When it abuts against the fixed guide cylinder 233, the two together define a closed cylindrical space, ensuring that the detector can accurately pass through the space and be clamped. The floating connecting member 237 is used to drive the clamping roller 235 and the floating guide cylinder 236 to move synchronously.

[0069] It should be noted that, during operation, the reciprocating module 24 drives the clamping seat 231 to move on the lifting module 12, so that the clamping module 23 is in a proper position. Then, the clamping cylinder 234 is activated, pushing the floating connection 237, so that the floating clamping roller 235 moves toward the fixed clamping roller 232, and the floating guide cylinder 236 moves toward the fixed guide cylinder 233. When the floating guide cylinder 236 contacts the fixed guide cylinder 233, the two together form a closed cylindrical space, and the detector passes through this cylindrical space and is firmly clamped by the fixed clamping roller 232 and the floating clamping roller 235.

[0070] Then, the detector is positioned in the clamping module 23. Then, the sliding drive 221 in the sliding module 22 drives the sliding seat 223 together with the coiling module 21 thereon to move to the coiling position 21a. The coiling motor 213 starts and drives the coiling shaft 215 to rotate through the coiling transmission gear set 214, and starts to coil the detector. Since the position of the clamping module 23 is adjusted by the reciprocating module 24, the detector can be coiled one circle at a time at different positions of the coiling module 21, ensuring that the winding process is uniform and orderly.

[0071] After finishing coiling, the sliding drive 221 moves again, and the sliding seat 223 is moved to the release position 21b together with the coiling module 21. At this time, the clamping cylinder 234 operates in the opposite direction, and the floating clamping roller 235 and the floating guide cylinder 236 are returned to the original position, so that subsequent processing or storage.

[0072] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the reciprocating module 24 includes a reciprocating motor 241, a reciprocating guide rail 242, a reciprocating drive shaft 243 and a reciprocating seat 244. The reciprocating motor 241 and the reciprocating guide rail 242 are respectively arranged on the lifting module 12, and the reciprocating seat 244 is slidably arranged on the reciprocating guide rail 242; the clamping module 23 is arranged on the reciprocating seat 244. The reciprocating drive shaft 243 is penetrated and screwed to the reciprocating seat 244, so that when the reciprocating drive shaft 243 rotates, the reciprocating seat 244 is driven to slide along the reciprocating guide rail 242, thereby adjusting the relative position of the clamping module 23 and the coiling position 21a.

[0073] It can be understood that the reciprocating motor 241 is used to output torque, thereby driving the reciprocating drive shaft 243 to rotate. The reciprocating guide rail 242 is used to provide a precise sliding path for the reciprocating seat 244. When the reciprocating drive shaft 243 rotates, the reciprocating seat 244 is driven to slide along the reciprocating guide rail 242 through the threaded connection. The movement of the reciprocating seat 244 is controlled by the reciprocating drive shaft 243, thereby driving the clamping module 23 to adjust its position.

[0074] It should be noted that after the reciprocating motor 241 is started, the reciprocating drive shaft 243 is driven to rotate through the transmission mechanism. Since the reciprocating drive shaft 243 is threadedly connected to the reciprocating seat 244, its rotation is converted into a linear motion of the reciprocating seat 244 along the reciprocating guide rail 242.

[0075] like Figure 7 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the clamping module 23 further includes a reciprocating limit switch 238 and a position avoidance limit switch 239, and the reciprocating limit switch 238 and the position avoidance limit switch 239 are both arranged on the reciprocating guide rail 242;

[0076] When the reciprocating limit switch 238 is triggered, the reciprocating motor 241 drives the reciprocating drive shaft 243 to rotate in the opposite direction; when the avoidance limit switch 239 is triggered, the reciprocating motor 241 stops, thereby fixing the position of the reciprocating seat 244 on the reciprocating guide rail 242.

[0077] It can be understood that the reciprocating limit switch 238 is used to control the reverse rotation of the reciprocating motor 241. When the reciprocating limit switch 238 is triggered, it indicates that the reciprocating seat 244 has reached the set maximum stroke position. At this time, the reciprocating motor 241 will drive the reciprocating drive shaft 243 to rotate in the opposite direction to return the reciprocating seat 244. The avoidance limit switch 239 is used to control the shutdown of the reciprocating motor 241. When the avoidance limit switch 239 is triggered, it indicates that the reciprocating seat 244 has reached the set safety stop position. At this time, the reciprocating motor 241 is stopped and the reciprocating seat 244 is fixed at the current position on the reciprocating guide rail 242.

[0078] It should be noted that the setting of the reciprocating limit switch 238 and the avoidance limit switch 239 enhances the automation and safety of the system. By precisely controlling the moving range of the reciprocating seat 244, the stability and accuracy of the detector during the entire storage process are guaranteed, reducing operational risks and improving work efficiency.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the nuclear power detector shrinkage storage mechanism further includes a storage assembly 3, and the storage assembly 3 includes a sliding connection module 31 and a storage module 32;

[0080] The sliding receiving module 31 is movably arranged on the lifting module 12, and the storage assembly 3 is arranged in the core pool. The sliding receiving module 31 is used to receive the detector detached from the coiling module 21, and the storage assembly 3 is used to store the coiled detector.

[0081] It can be understood that the sliding receiving module 31 is used to receive the detector that has escaped from the coiling module 21. The sliding receiving module 31 can move on the lifting module 12 to ensure that it can accurately dock with the detector after coiling. The storage module 32 is used to finally store the detector after coiling. The storage module 32 is designed with a suitable storage space to accommodate the processed detector to ensure its safe storage. The main function of the storage component 3 is to ensure that the detector can be safely transferred and properly stored after the coiling is completed to avoid any unexpected situation during the operation.

[0082] It should be noted that after the detector is coiled, the detector has been coiled from the original long strip to a spiral shape. At this time, the sliding receiving module 31 is started and moved to an appropriate position to receive the detector that has escaped from the coiling module 21. The sliding receiving module 31 is used to receive the detector to prevent it from being damaged during the transfer process. After the receiving is completed, the sliding receiving module 31 transfers the detector to the storage module 32, which is used for the storage and storage of the detector.

[0083] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinkage storage mechanism 10, the sliding receiving module 31 includes a sliding guide rail 311, a sliding seat 312, a sliding drive member 313, a receiving slide rail 314, a receiving channel 315 and a receiving drive member 316;

[0084] The sliding guide rail 311 and the sliding driving member 313 are respectively arranged on the sliding seat 223, the sliding seat 312 is slidably arranged on the sliding guide rail 311, and the sliding driving member 313 is drivingly connected to the sliding seat 312. The sliding driving member 313 is used to drive the sliding seat 312 to slide along the sliding guide rail 311, so that the receiving channel 315 is aligned with or staggered from the reel module 21;

[0085] The guiding slide rail 314 is set on the sliding seat 312, the guiding channel 315 is slidably set on the guiding slide rail 314, the guiding driving member 316 is drivingly connected to the guiding channel 315, the guiding driving member 316 drives the guiding channel 315 to move towards or away from the coil module 21, and the guiding channel 315 is for the detector to fall into and guides the detector to fall into the storage component 3.

[0086] It can be understood that the sliding guide rail 311 is fixedly arranged on the sliding seat 223 to provide a precise sliding path for the sliding seat 312. The sliding seat 312 can move along the sliding guide rail 311 under the action of the sliding drive member 313. The sliding drive member 313 can drive the sliding seat 312 to move along the sliding guide rail 311, so that the receiving channel 315 can be accurately aligned with or staggered from the winding module 21; wherein, when the receiving channel 315 is aligned with the winding module 21, it is used to receive the detector that escapes after winding, and when the receiving channel 315 is staggered from the winding module 21, it is used to provide activity space for the remaining mechanisms for the next detector to be wound. The receiving slide rail 314 provides a sliding path for the receiving channel 315. The receiving channel 315 is used for the detector to fall into and guide the detector into the storage module 32. The receiving drive member 316 is used to move the receiving channel 315 in a direction close to or away from the winding module 21.

[0087] When the receiving drive 316 is started, it can make the receiving channel 315 accurately align with the coil module 21, ensuring that the detector can be smoothly transferred from the coil module 21 to the receiving channel 315.

[0088] like Figure 7 As shown, in some embodiments of the nuclear power detector retractable storage mechanism 10, the sliding connection module 31 also includes a blocking cylinder 317 and a baffle 318. The blocking cylinder 317 is arranged on the sliding seat 223, and the baffle 318 is slidably arranged on the connection channel 315. The blocking cylinder 317 is driven and connected to the baffle 318. The blocking cylinder 317 is used to drive the baffle 318 to cut off or open the connection channel 315.

[0089] It can be understood that the blocking cylinder 317 is used to drive the baffle 318 to cut off or open the access channel 315. The baffle 318 is driven by the blocking cylinder 317 and can move in the access channel 315 to cut off or open the channel.

[0090] It should be noted that the baffle 318 can be configured to be located between the two ends of the receiving channel 315 or at the end of the receiving channel 315 for material to fall. Specifically, when the baffle 318 cuts off the receiving channel 315, the detector falling into the receiving channel 315 will be confined in the receiving channel 315 by the baffle 318; when the baffle 318 opens the receiving channel 315, the detector can fall out of the receiving channel 315.

[0091] like Figures 2 to 4As shown, in some embodiments of the lifting module 12, the lifting module 12 includes a lifting installation frame 121, a lifting drive 122, a lifting shaft 123, a lifting connection cable 124, a lifting seat 125, a lifting pulley 126 and a lifting fixed pulley 127. The lifting installation frame 121 is fixedly arranged on the core pool, the lifting drive 122 is arranged on the lifting installation frame 121, the lifting drive 122 is driven and connected to the lifting shaft 123, the lifting connection cable 124 is wound on the lifting shaft 123, the lifting pulley 126 is arranged on the lifting seat 125, and the lifting fixed pulley 127 is arranged on the lifting installation frame 121. Among them, the shrinking component 2 is arranged on the lifting seat 125.

[0092] It can be understood that the lifting mounting frame 121 serves as the basic support of the entire lifting module 12. The lifting drive 122 is the power source for driving the lifting shaft 123 to rotate. It can be realized by a motor or other forms of power devices. The lifting shaft 123 is used to wind the lifting connection cable 124. When the lifting drive 122 is started, the lifting shaft 123 rotates, driving the lifting connection cable 124 to perform a retracting operation. One end of the lifting connection cable 124 is fixed on the lifting seat 125, and the other end is wound around the lifting shaft 123. Through the rotation of the lifting shaft 123, the lifting connection cable 124 can lift or lower the lifting seat 125.

[0093] The lifting seat 125 is used to carry the shrinking assembly 2 (including the coiling module 21, the clamping module 23, etc.). As the lifting connecting cable 124 is retracted and released, the lifting seat 125 can move up and down along the lifting mounting frame 121. The lifting pulley 126 is used to guide and support the lifting connecting cable 124 to ensure that it runs smoothly during the lifting process. The lifting fixed pulley 127 is used to change the direction of the lifting connecting cable 124 to ensure that it can be smoothly transferred from the lifting shaft 123 to the lifting seat 125 and reduce friction.

[0094] The implementation of the present invention has the following beneficial effects:

[0095] The present invention relates to a nuclear power detector shrinkage storage mechanism, which can wind up a pulled-out detector by setting a shrinkage component. The detector can be wound into a multi-layer spiral shape, making the detector more compact as a whole; in this way, the wound detector is easier to store, which improves the handling convenience of the pulled-out detector.

[0096] Secondly, the present invention also achieves a high degree of automation in the detector winding process through the setting of the lifting component and the shrinking component. The sliding module can drive the winding module to switch between the winding position and the release position, so that the wound detector can be unloaded in time; and the reciprocating module is used to adjust the position of the clamping module to ensure that the detector can be stably and orderly wound on the winding module. The setting of the clamping module can enable the detector to maintain a certain tension during the winding process, so that the detector can be wound more tightly, making the wound detector more compact and easier to store and process.
