[0044] Figure 1 The nuclear power detector shrinkage receiving mechanism 10 in some embodiments of the present application is shown, which includes a lifting assembly 1 and a shrinkage assembly 2, the lifting assembly 2 is arranged in the core pool, and the lifting assembly 1 is drivingly connected to the shrinkage assembly 2. It can be understood that the lifting assembly 1 is used to drive the shrinkage assembly 2 to move in the core pool. The shrinkage assembly 2 is used to coil and store the detector.

[0045] As shown in Figure 2 and Figure 3 The lifting assembly 1 includes a lifting track 11 and a lifting module 12 slidingly arranged on the lifting track 11.

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

[0047] As shown in Figures 2 to 7As shown, the shrinkage 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 slidingly arranged on the lifting module 12. The sliding module 22 is drivingly connected to the coiling module 21. The clamping module 23 is slidingly arranged on the lifting module 12. The reciprocating module 24 is drivingly 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 release position 21b. The coiling module 21 rotates at the coiling position 21a to coil the probe. After the coiling module 21 moves to the release position 21b, the coiled probe is released.

[0049] The probe is clamped by the clamping module 23 and then connected to the coiling position 21a. The reciprocating module 24 is used to drive the clamping module 23 to move on the lifting module 12, so as to adjust the relative position of the clamping module 23 and the coiling position 21a, and thus the probe can be wound on the coiling module 21 turn by turn.

[0050] It can be understood that the coiling module 21 is slidingly installed on the lifting module 12 and can be converted 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 probe. After moving to the release position 21b, the coiled probe 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 slidingly arranged on the lifting module 12 and is responsible for clamping the probe and connecting it to the coiling position 21a. The reciprocating module 24 drives the clamping module 23 to move on the lifting module 12, so as to adjust the relative position of the clamping module 23 and the coiling position 21a, and thus the probe can be wound on the coiling module 21 turn by turn.

[0051] It should be noted that during the working process, the probe is first fixed and guided to the coiling position 21a by using the clamping module 23. 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 probe can be uniformly 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] As Figures 4 to 7As shown, in some embodiments of the nuclear power detector shrinkage and storage mechanism 10, the sliding module 22 includes a sliding drive 221, a sliding track 222, and a sliding seat 223. The sliding drive 221 and the sliding track 222 are respectively disposed on the lifting module 12. The sliding seat 223 is slidably disposed on the sliding track 222. The sliding drive 221 is driven and connected to the sliding seat 223. The winding module 21 is disposed on the sliding seat 223. The winding module 21 is driven by the sliding seat 223 to move between the winding position 21a and the release position 21b.

[0053] Understandably, the coiling module 21 is mounted 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 on it 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 base 223. The sliding drive 221 can be a motor or other form of power source, which can control the moving distance and speed of the sliding base 223 to adapt to the needs of detectors of different lengths and types. The sliding base 223 not only serves as the carrier of the winding module 21, but also, through its cooperation with the sliding track 222, ensures the stability and accuracy of the winding module 21 during movement. This allows the winding module 21 to switch smoothly between the winding position 21a and the release position 21b, improving the response speed and working efficiency of the entire device.

[0055] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinking and 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 disposed on the sliding seat 223, the coiling sealing cylinder 212 is disposed on the coiling seat 211, the coiling motor 213 is disposed inside the coiling sealing cylinder 212, the coiling motor 213 is driven and connected to the coiling transmission gear set 214, and the coiling transmission gear set 214 is driven and connected to the coiling shaft 215.

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

[0057] Understandably, the reel holder 211 provides basic support for the entire reel module 21. The reel sealing cylinder 212 protects the internal components from external environmental influences while providing a closed working space. The reel motor 213 is the power source that drives the reel shaft 215 to rotate. It is connected to an external control system via electrical or mechanical connection and starts or stops upon receiving commands. The reel drive gear set 214 is responsible for transmitting power and adjusting speed and torque. This gear set ensures efficient energy conversion from the motor to the shaft; furthermore, the reel drive gear set 214 can be configured to include several transmission gears, through which power is transmitted. When the reel motor 213 operates, it drives the reel shaft 215 to rotate via the reel drive gear set 214, allowing the detector to be evenly wound around the reel shaft 215.

[0058] It should be noted that during operation, the clamping module 23 first secures and guides the detector to the winding position 21a. Then, the sliding drive 221 in the sliding module 22 drives the sliding seat 223, along with the winding module 21 on it, to move to the winding position 21a. At this time, the winding motor 213 starts and drives the winding shaft 215 to rotate through the winding transmission gear set 214, beginning the winding of the detector. Simultaneously, the reciprocating module 24 adjusts the position of the clamping module 23 to ensure that the detector can be evenly wound onto the winding shaft 215. After winding is completed, the sliding drive 221 actuates again, moving the sliding seat 223 and the winding module 21 together to the release position 21b for subsequent processing or storage.

[0059] like Figure 6 As shown, in some embodiments of the nuclear power detector shrinking and storage mechanism 10, the coiling module 21 further includes a first side plate 216, an ejection guide rail 217, a second side plate 218, an ejection drive component 219, and an auxiliary roller 2100.

[0060] The first side plate 216 and the ejection guide rail 217 are respectively disposed on the lifting module 12. The second side plate 218 is slidably disposed on the ejection guide rail 217. The ejection drive member 219 is driven to be connected to the second side plate 218. One end of the auxiliary roller 2100 is connected to the second side plate 218. The second side plate 218 is driven by the ejection drive member 219 to move towards 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. The auxiliary roller 2100 and the winding shaft 215 respectively abut against the detector from opposite sides.

[0061] Understandably, the first side plate 216 serves as one end docking point of the auxiliary roller 2100. The ejection 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 ejection drive member 219. The ejection drive member 219 drives the second side plate 218 to move towards or away from the first side plate 216. The auxiliary roller 2100 can insert into or remove from the first side plate 216 when the second side plate 218 moves. When the auxiliary roller 2100 is inserted into the first side plate 216, the auxiliary roller 2100 and the winding shaft 215 abut against the detector from opposite sides, ensuring that the detector remains stable during the winding process and preventing it from shifting or becoming unevenly wound.

[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, along with the coiling module 21 on it, to move to the coiling position 21a. At the same time, the ejection drive 219 is activated, pushing the second side plate 218 to slide along the ejection 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 activated and drives the coiling shaft 215 to rotate through the coiling transmission gear set 214, starting the coiling of the detector. The presence of the auxiliary roller 2100 ensures the stability of the detector during the coiling process and avoids unnecessary twisting or damage.

[0063] After the winding is completed, the sliding drive 221 actuates again, moving the sliding seat 223 together with the winding module 21 to the release position 21b. At this time, the push-out drive 219 rotates in reverse, causing the second side plate 218 to retract and the auxiliary roller 2100 to disengage from the first side plate 216, so that the auxiliary roller 2100 can disengage from the detector after winding, facilitating the disengagement of the detector after winding.

[0064] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinking and 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 drivingly connected to the clamping seat 231, the fixed clamping roller 232 and the fixed guide cylinder 233 are arranged on the clamping seat 231, the clamping cylinder 234 is arranged on the clamping seat 231 and is drivingly connected to the floating connecting piece 237, the floating clamping roller 235 and the floating guide cylinder 236 are arranged on the floating connecting piece 237, the clamping cylinder 234 drives the floating connecting piece 237 to move, so that the floating clamping roller 235 moves towards or away from the fixed clamping roller 232, and the floating guide cylinder 236 moves towards 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 probe is arranged in the cylindrical space and is clamped between the fixed clamping roller 232 and the floating clamping roller 235, so that the probe moves on the clamping seat 231 and is wound at different positions on the coiling module 21.

[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 drivingly 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 clamp the probe in cooperation with the floating clamping roller 235. The fixed guide cylinder 233 and the floating guide cylinder 236 jointly define a cylindrical space for the probe to pass through, so as to guide the probe; wherein the probe itself has a certain flexibility and is prone to deformation after being inserted into the core for a long time.

[0068] The clamping cylinder 234 moves the floating clamping roller 235 towards or away from the fixed clamping roller 232 by providing power. The floating clamping roller 235 can move under the action of the clamping cylinder 234 and cooperates with the fixed clamping roller 232 to ensure that the probe can be stably clamped and coiled when being guided to the coiling position 21a. The floating guide cylinder 236 is also arranged on the floating connecting piece 237, and when it abuts against the fixed guide cylinder 233, the two jointly define a closed cylindrical space to ensure that the probe can accurately pass through the space and be clamped. The floating connecting piece 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, positioning the clamping module 23 in the appropriate position. Then, the clamping cylinder 234 is activated, pushing the floating connector 237, causing the floating clamping roller 235 to move towards the fixed clamping roller 232, while the floating guide cylinder 236 moves towards 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. The detector passes through this cylindrical space and is firmly clamped by the fixed clamping roller 232 and the floating clamping roller 235.

[0070] Subsequently, the detector is positioned within the clamping module 23. Then, the sliding drive 221 in the sliding module 22 drives the sliding seat 223, along with the winding module 21 thereon, to move to the winding position 21a. The winding motor 213 starts and drives the winding shaft 215 to rotate via the winding transmission gear set 214, beginning the winding of the detector. Because the position of the clamping module 23 is adjusted by the reciprocating module 24, the detector can be wound round by round at different positions on the winding module 21, ensuring a uniform and orderly winding process.

[0071] After the coiling is completed, the sliding drive 221 actuates again, moving the sliding seat 223 together with the coiling module 21 to the release position 21b. At this time, the clamping cylinder 234 operates in reverse, causing the floating clamping roller 235 and the floating guide cylinder 236 to return to their original positions for subsequent processing or storage.

[0072] like Figures 4 to 7 As shown, in some embodiments of the nuclear power detector shrinking and 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 mounted on the lifting module 12, and the reciprocating seat 244 is slidably mounted on the reciprocating guide rail 242. The clamping module 23 is mounted on the reciprocating seat 244. The reciprocating drive shaft 243 passes through and is screwed to the reciprocating seat 244, so that when the reciprocating drive shaft 243 rotates, it drives the reciprocating seat 244 to slide along the reciprocating guide rail 242, thereby adjusting the relative position of the clamping module 23 and the winding position 21a.

[0073] Understandably, the reciprocating motor 241 outputs torque to drive the reciprocating drive shaft 243 to rotate. The reciprocating guide rail 242 provides a precise sliding path for the reciprocating seat 244. When the reciprocating drive shaft 243 rotates, it drives the reciprocating seat 244 to slide along the reciprocating guide rail 242 via a threaded connection. The movement of the reciprocating seat 244 is controlled by the reciprocating drive shaft 243, which in turn drives the clamping module 23 to adjust its position.

[0074] It should be noted that after the reciprocating motor 241 starts, it drives the reciprocating drive shaft 243 to rotate through the transmission mechanism. Since the reciprocating drive shaft 243 and the reciprocating seat 244 are connected by a thread, its rotation is converted into the 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 shrinking and storage mechanism 10, the clamping module 23 also includes a reciprocating limit switch 238 and an avoidance limit switch 239, both of which are mounted 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] Understandably, 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 reverse direction, causing the reciprocating seat 244 to return. The avoidance limit switch 239 is used to control the stopping of the reciprocating motor 241. When the avoidance limit switch 239 is triggered, it indicates that the reciprocating seat 244 has reached the set safe stop position. At this time, the reciprocating motor 241 stops, fixing the reciprocating seat 244 to its current position on the reciprocating guide rail 242.

[0078] It should be noted that the reciprocating limit switch 238 and the avoidance limit switch 239 enhance the automation and safety of the system. By precisely controlling the movement range of the reciprocating seat 244, the stability and accuracy of the detector are ensured throughout the storage process, 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 and storage mechanism 10, the nuclear power detector shrinkage and storage mechanism further includes a storage component 3, which includes a sliding guide module 31 and a storage module 32.

[0080] The sliding guide module 31 is movably mounted on the lifting module 12, and the storage component 3 is disposed in the core pool. The sliding guide module 31 is used to guide the detector that comes off the coiling module 21, and the storage component 3 is used to store the coiled detector.

[0081] Understandably, the sliding guide module 31 is used to guide the detector detached from the reeling module 21. The sliding guide module 31 can move on the lifting module 12 to ensure accurate docking with the reeled detector. The storage module 32 is used to finally store the reeled detector. The storage module 32 is designed with suitable storage space to accommodate the processed detector and ensure its safe storage. The main function of the storage assembly 3 is to ensure that the detector can be safely transferred and properly stored after reeling, avoiding any accidents during operation.

[0082] It should be noted that after the detector is coiled, it has changed from a long strip to a spiral shape. At this point, the sliding guide module 31 is activated and moved to a suitable position to guide the detector that has detached from the coiling module 21. The sliding guide module 31 is used to catch the detector and prevent it from being damaged during the transfer process. After the guide is completed, the sliding guide module 31 transfers the detector to the storage module 32, which is used for the storage and handling of the detector.

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

[0084] The sliding guide rail 311 and the sliding drive 313 are respectively disposed on the sliding seat 223. The sliding seat 312 is slidably disposed on the sliding guide rail 311. The sliding drive 313 is driven to be connected to the sliding seat 312. The sliding drive 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 offset from the coiling module 21.

[0085] The guide rail 314 is mounted on the sliding seat 312, the guide channel 315 is slidably mounted on the guide rail 314, the guide drive 316 is driven to connect to the guide channel 315, the guide drive 316 drives the guide channel 315 to move toward or away from the coiling module 21, and the guide channel 315 allows the detector to fall into and guide the detector to fall into the storage assembly 3.

[0086] Understandably, the sliding guide rail 311 is fixedly mounted on the sliding seat 223, providing 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, enabling the guide channel 315 to accurately align with or offset from the coiling module 21. When aligned with the coiling module 21, the guide channel 315 is used to guide the detector that has been coiled and detached; when offset from the coiling module 21, the guide channel 315 provides space for the remaining mechanisms to coil the next detector. The guide rail 314 provides a sliding path for the guide channel 315. The guide channel 315 is used to allow the detector to fall into and guide the detector into the receiving module 32. The guide drive member 316 is used to move the guide channel 315 towards or away from the coiling module 21.

[0087] When the receiving drive 316 is activated, it can precisely align the receiving channel 315 with the reel module 21, ensuring that the detector can be smoothly transferred from the reel module 21 to the receiving channel 315.

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

[0089] Understandably, the blocking cylinder 317 is used to drive the baffle 318 to cut off or open the receiving channel 315. The baffle 318, driven by the blocking cylinder 317, is able to move within the receiving 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 where the material is to fall. Specifically, when the baffle 318 cuts off the receiving channel 315, the detector falling into the receiving channel 315 will be confined within the receiving channel 315 by the baffle 318; when the baffle 318 opens the receiving channel 315, the detector can fall out from 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 mount 121, a lifting drive 122, a lifting shaft 123, a lifting connecting cable 124, a lifting seat 125, a lifting pulley 126, and a lifting fixed pulley 127. The lifting mount 121 is fixedly arranged on the core pool. The lifting drive 122 is arranged on the lifting mount 121. The lifting drive 122 is drivingly connected to the lifting shaft 123. The lifting connecting cable 124 is wound on the lifting shaft 123. The lifting pulley 126 is arranged on the lifting seat 125. The lifting fixed pulley 127 is arranged on the lifting mount 121. The volume reduction assembly 2 is arranged on the lifting seat 125.

[0092] Understandably, the lifting mount 121 serves as the basic support of the entire lifting module 12. The lifting drive 122 is a power source for driving the rotation of the lifting shaft 123. It can be achieved by a motor or other forms of power device. The lifting shaft 123 is used for winding the lifting connecting cable 124. When the lifting drive 122 is started, the lifting shaft 123 rotates, driving the lifting connecting cable 124 to perform the winding and unwinding operation. One end of the lifting connecting cable 124 is fixed to the lifting seat 125, and the other end is wound on the lifting shaft 123. Through the rotation of the lifting shaft 123, the lifting connecting cable 124 can lift or lower the lifting seat 125.

[0093] The lifting seat 125 is used to carry the volume reduction assembly 2 (including the coiling module 21, the clamping module 23, etc.). With the winding and unwinding of the lifting connecting cable 124, the lifting seat 125 can move up and down along the lifting mount 121. The lifting pulley 126 is used to guide and support the lifting connecting cable 124, ensuring its smooth operation during lifting. The lifting fixed pulley 127 is used to change the direction of the lifting connecting cable 124, ensuring that it can be smoothly transmitted from the lifting shaft 123 to the lifting seat 125, and reducing the friction.

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

[0095] The present application relates to a nuclear power detector volume reduction storage mechanism, which can wind the pulled out detector by setting the volume reduction assembly. The detector can be wound into multiple layers of spiral shape, so that the whole detector is more compact. In this way, the wound detector is more convenient to store, and the processing convenience of the pulled out detector is improved.

[0096] Secondly, the application also realizes high automation of the detector winding process through the arrangement of the lifting assembly and the capacity reduction assembly. 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 timely discharged; and the reciprocating module is used for adjusting the position of the clamping module, so as to ensure that the detector can be stably and orderly wound on the winding module. The arrangement of the clamping module can make the detector maintain a certain tension during winding, so that the detector can be more tightly wound, and the wound detector is more compact, which is more convenient for subsequent storage and processing.
