[0022] Figures 1 to 3 The tensile monitoring device 1 according to some embodiments of the present invention is shown, which includes a protective component 11, a tensile sensing component 12, a torque connection component 13, a transmission component 14, and a sealing component 15.

[0023] like Figures 1 to 4 As shown, the protective assembly has a receiving cavity 114 and two connecting holes 1131, which are respectively connected to the receiving cavity 114. A tension sensing assembly 12 is disposed within the receiving cavity 114. A torque connection assembly 13 includes two connectors 131, which are respectively connected to both ends of the tension sensing assembly 12. The two connectors 131 are correspondingly inserted through the two connecting holes 1131, and both connectors 131 are fixedly connected to the protective assembly. A transmission assembly 14 passes through the protective assembly and is electrically connected to the tension sensing assembly 12. A sealing assembly 15 includes two sealing elements 151, which are correspondingly disposed on the two connectors 131. Each sealing element 151 is used to seal the mating position between the connecting hole 1131 and the connector 131.

[0024] Understandably, the protective component 11 provides a closed and protected working environment for the tension sensing component 12. Specifically, the housing cavity 114 functions to house and isolate the tension sensing component 12, preventing external environmental factors (such as liquids, corrosive substances, or mechanical impacts) from directly contacting the internal components, thereby ensuring the stability and reliability of the tension sensing process. The opening of the connection hole 1131 allows the connector 131 of the torque connection component 13 to pass through, while maintaining the overall sealing of the housing cavity 114.

[0025] The tension sensing component 12 monitors and measures the tension or stress signal applied to the device in real time. Its function is to convert mechanical force into an electrical signal, and output accurate stress data by sensing the torque change transmitted through the sensing connector 131.

[0026] The torque connection assembly 13 enables stable torque transmission and mechanical connection. The connector 131 ensures that externally applied tension or torque is transmitted promptly and accurately to the tension sensing assembly 12.

[0027] The transmission component 14 provides a data communication link between the product's internal and external devices. Its function is to stably transmit the electrical signal generated by the tension sensing component 12 to an external monitoring system (such as a control center or data recording device), enabling real-time data feedback and remote monitoring, and ensuring the continuity and accessibility of stress information.

[0028] The function of the sealing assembly 15 is to enhance the sealing performance of the device and prevent liquid penetration. The seal 151 is used to form a reliable seal at the mating position of the connecting hole 1131 and the connector 131, effectively preventing liquid from entering the receiving cavity 114 during torque transmission, and ensuring the dryness and safe operation of the internal components of the receiving cavity 114.

[0029] It should be noted that the cooperation between the protective component 11 and the sealing component 15 ensures the complete sealing of the receiving cavity 114, effectively preventing the intrusion of liquids, moisture, or contaminants, thereby significantly improving the reliability and lifespan of the device in underwater or high-humidity environments. Furthermore, the overall structure of the tensile monitoring device 1 of the present invention simplifies maintenance requirements, reduces the failure rate, and is particularly suitable for harsh industrial scenarios such as nuclear power plants, improving equipment safety and operational efficiency.

[0030] like Figures 2 to 4As shown, in some embodiments of the tensile monitoring device 1, the protective assembly includes a cover 111, a cap 112, and two side covers 113. The cover 111 has a positioning hole 1111 and two mounting holes 1112. The cap 112 covers the positioning hole 1111, and the two side covers 113 are correspondingly covered in the two mounting holes 1112. The cover 111, the cap 112, and the two side covers 113 together enclose a storage cavity 114. Each side cover 113 has a connection hole 1131, and the transmission assembly 14 passes through the cap 112.

[0031] Understandably, the housing 111, the cover 112, and the two side covers 113 work together to protect the tension sensing assembly 12. The positioning hole 1111 provides a passage for the transmission assembly 14 to pass through. The mounting hole 1112 is used to receive and mount the side covers 113.

[0032] The cover 112 is used to seal the positioning hole 1111, blocking the path of external media into the receiving cavity 114. The side cover 113 is used to cover and seal the mounting hole 1112, and the connection hole 1131 on the side cover 113 provides a passage for the connector 131. The transmission assembly 14 is used to maintain data transmission between the tension sensing assembly 12 and external devices while maintaining the sealing of the cover 112.

[0033] like Figures 2 to 4 As shown, in some embodiments of the tensile monitoring device 1, the cover 111 is provided with a connecting neck 1113, the positioning hole 1111 is located at one end of the connecting neck 1113, the other end of the connecting neck 1113 is connected to the receiving cavity 114, and the cover 112 is placed on the connecting neck 1113. The sealing assembly 15 also includes a sealing gasket 152, which is disposed between the end of the cover 112 and the connecting neck 1113, and the sealing gasket 152 abuts against the cover 112 and the connecting neck 1113 respectively.

[0034] Understandably, the design of the connecting neck 1113 extends the passage from the positioning hole 1111 to the receiving cavity 114, thereby providing more space for cable routing within the housing 111. Simultaneously, it allows the insertion point of the transmission assembly 14 to be moved outward, reducing the risk of direct exposure. The sealing gasket 152 fills the mating gap between the cover 112 and the end of the connecting neck 1113 through compression deformation, achieving a reliable and stable seal.

[0035] like Figure 2 and Figure 3As shown, in some embodiments of the tensile monitoring device 1, the side cover 113 is provided with an insertion part 1132, and the insertion part 1132 is provided with a plurality of annular grooves 1133. Each annular groove is provided with an annular seal 1134. The insertion part 1132 is inserted into the mounting hole 1112, and each annular seal 1134 abuts against the hole wall of the mounting hole 1112 and the insertion part 1132 respectively.

[0036] Understandably, the insertion part 1132 can increase the mating surface between the side cover 113 and the wall of the mounting hole 1112, thereby improving the sealing performance at the contact point between the two. At the same time, the opening of the annular groove 1133 and the setting of the annular seal 1134 further enhance the sealing performance between the insertion part 1132 and the wall of the mounting hole 1112, thereby further improving the sealing and isolation performance of the product.

[0037] It should be noted that by setting multiple annular grooves 1133 and multiple annular seals 1134, a stable and reliable seal can be formed at multiple different positions on the insertion part 1132, effectively ensuring the sealing performance of the mating position.

[0038] like Figures 1 to 4 As shown, in some embodiments of the tensile monitoring device 1, each seal 151 includes at least one sealing ring, and each connector 131 has at least one sealing groove 1311. Each sealing ring is correspondingly disposed in each sealing groove 1311, and each sealing ring abuts against the wall of the connecting hole 1131.

[0039] Understandably, configuring the seal 151 as a sealing ring allows the elastic deformation of the sealing ring to fill the mating gap between the sealing groove 1311 and the wall of the connecting hole 1131, forming a radial compression seal. The sealing groove 1311 is used to install and position the sealing ring, ensuring that the sealing ring can always form a stable and reliable seal in the predetermined position.

[0040] It should be noted that, through the content of this embodiment, the elastic deformation of the sealing ring can adapt to the torque transmission micro-displacement of the connector 131, completely blocking the circumferential leakage path of liquid along the wall of the connecting hole 1131, and improving the sealing reliability of the nuclear power cold source interception net body in turbulent environment.

[0041] like Figures 1 to 4 As shown, in some embodiments of the tension monitoring device 1, each connector 131 is provided with a receiving hole 1312 and an external connection hole 1313. The receiving hole 1312 is for the end of the tension sensing component 12 to be inserted, and the external connection hole 1313 is exposed outside the protective component.

[0042] Understandably, the receiving hole 1312 is used to accommodate the end insertion installation of the tension sensing component 12, and the direct and rapid transmission of torque is achieved through the surface contact between the inner wall of the receiving hole 1312 and the end of the tension sensing component 12. The function of the external hole 1313 is to be exposed to the outside of the protective component, providing a standardized assembly interface (such as threaded connection, pin fixing, snap-fit ​​fixing or other feasible fixing methods in the prior art) for the interception net or other mechanical structures.

[0043] It should be noted that, in this type of embodiment, the depth of the accommodating hole 1312 ensures the coaxiality of torque transmission; of course, the specific insertion depth can be flexibly adjusted. The open interface of the external hole 1313 reduces the difficulty of product installation and maintenance, and improves the ease of operation.

[0044] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, connector 131 also includes shackle 132, which is detachably connected to external hole 1313.

[0045] Understandably, shackle 132 can be quickly disassembled and assembled, and in practical applications, the interception net and shackle 132 can be connected separately through other connecting elements, which improves the ease of product installation.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments of the tensile monitoring device 1, the transmission component 14 includes a sealing sleeve 141, a watertight plug 142, and a transmission cable 143. The sealing sleeve 141 is disposed on the cover 112, the watertight plug 142 is disposed on the tensile sensing component 12, and the transmission cable 143 passes through the sealing sleeve 141 and is further connected to the watertight plug 142.

[0047] Understandably, the sealing sleeve 141 is used to wrap the transmission cable 143, which, together with the cover 112, encloses a space isolated from the outside world. However, this space is connected to the receiving cavity 114. This space isolates and protects the transmission cable 143, preventing liquid from seeping in through the cable's penetration point on the cover 112. The watertight plug 142 is located inside the receiving cavity 114. The watertight plug 142 is a common underwater sealing plug in the prior art. The watertight plug prevents water vapor penetration, further improving the product's reliability in underwater environments.

[0048] Furthermore, in some embodiments, the transmission component 14 also includes a watertight conduit that is fitted over the transmission cable 143. This allows the transmission cable 143 to be protected by the watertight conduit, isolating it from the underwater environment and further improving the reliability of the product for underwater use.

[0049] like Figure 4 As shown, in some embodiments of the tension monitoring device 1, the central axis L1 of both connectors 131 coincides with the central axis L2 of the tension sensing component 12.

[0050] Understandably, by aligning the central axes in this embodiment, the externally applied tensile force is ensured to be transmitted to the tensile sensing component 12 along a single axis, eliminating measurement errors caused by off-center load torque and improving measurement accuracy.

[0051] It should be noted that, in this embodiment, the force transmission path of the tension monitoring device 1 is completely consistent with the sensing direction by the absolutely coaxial arrangement of the connector 131 and the tension sensing component 12.

[0052] Figure 5 The following is an illustration of a stress sensing device 20 for a nuclear power cold source interception net body in some embodiments of the present invention, which includes a tensile monitoring device 1 and a communication cabinet 30, the communication cabinet 30 being electrically connected to a transmission component 14.

[0053] Understandably, the communication cabinet 30 is used to receive data from the tensile monitoring device 1 and execute corresponding instructions based on the obtained data, or to further send the data to other data processing terminals for processing. In some embodiments, by obtaining data from the tensile monitoring device 1 through the communication cabinet 30, stress data at key locations of the nuclear power plant cold source interception network can be obtained. This stress data can serve as an important reference for judging the operational status of the interception network, which is crucial for protecting the safety of cold source water intake and ensuring the stable operation of the nuclear power plant.

[0054] like Figure 5 As shown, in some embodiments of the nuclear power cold source interception net body stress sensing device 20, the communication cabinet 30 includes a cabinet 40, a data exchange module 50, a processing module 60, and a power supply 70. The data exchange module 50, the processing module 60, and the power supply 70 are respectively disposed in the cabinet 40. The power supply 70 is electrically connected to the data exchange module 50 and the processing module 60 respectively. The data exchange module 50 is electrically connected to the transmission component, and the processing module 60 is electrically connected to the data exchange module 50.

[0055] Understandably, the cabinet 40 serves to house and protect the data exchange module 50 and the processing module 60. The power supply 70 provides power to the various modules and other electrical components on the cabinet 40. The data exchange module communicates with the tension sensing component 12 via the transmission component 14 to send and receive data. The processing module 60 performs predetermined processing on the data.

[0056] Since the specific data processing method is not within the scope of protection of this application, any component capable of acquiring and processing data is acceptable. The specific processing method or steps adopted will be adjusted according to the actual application scenario or application requirements.

[0057] The implementation of this invention has the following beneficial effects: This invention relates to a tensile monitoring device and a stress sensing device for a nuclear power plant cold source interception net. The stress sensing device for the nuclear power plant cold source interception net includes a tensile monitoring device. In the tensile monitoring device, the protective components allow the tensile sensing component to operate within a sealed housing cavity; the transmission components ensure stable communication between the tensile sensing component and external devices; and the sealing components ensure the sealing of the mating position between the torque connection component and the connection hole under stable torque transmission, preventing liquid from entering the housing cavity and avoiding contact between liquid and the tensile sensing component, thus improving the reliability of the product in underwater environments.
