DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In view of the above problems in the prior art, the present invention provides a deformation monitoring device for the corrugated enclosure structure of a cryogenic storage tank. Figure 1 Schematic diagram of the structure of the deformation monitoring device of the corrugated enclosure structure of the cryogenic storage tank provided by the present invention. Figure 1 As shown, the device comprises: a strain sensing optical cable 1 and a data analysis unit 2, wherein the strain sensing optical cable is circumferentially wound and laid on the surface of a corrugated enclosure structure 3 of a cryogenic storage tank; The strain sensing optical cable is used to detect the strain data of the corrugated enclosure structure of the cryogenic storage tank; The data analysis unit is used to determine the target deformation amount of the corrugated enclosure structure of the cryogenic storage tank based on the strain amount data.

[0027] Specifically, the strain sensing optical cable can be circumferentially wound and laid on the surface of the corrugated enclosure structure of the cryogenic storage tank, and fixed at a fixed point by a cryogenic structural adhesive. The strain sensing optical cable can detect the strain data of the corrugated enclosure structure of the cryogenic storage tank, and send the strain data to the data analysis unit. The data analysis unit can receive the strain data sent by the strain sensing optical cable, and can determine the target deformation of the corrugated enclosure structure of the cryogenic storage tank based on the strain data. It should be noted that the data analysis unit can first demodulate the corresponding variable data, and then determine the target deformation based on the demodulated strain data.

[0028] In one embodiment, the strain sensing optical cable 1 comprises an optical fiber 11 and a strain coupling layer 12; The strain coupling layer covers the optical fiber, and the optical fiber and the strain coupling layer are fixed by glue at a plurality of preset bonding points.

[0029] Specifically, the optical fiber can be passed through the strain coupling layer so that the strain coupling layer covers the optical fiber, and in the process, the optical fiber can be pre-tensioned by 3000 to 5000 microstrains. After the strain coupling layer covers the optical fiber, it can be fixed by glue at multiple preset bonding points to ensure that the strain coupling layer and the optical fiber can be deformed in coordination, and can also be marked at multiple preset bonding points after fixation. The glue can be a quick-drying glue. The bonding length of the strain coupling layer can be 3 to 5 mm.

[0030] In the above embodiment, a strain coupling layer is provided to cover the optical fiber, so that the strain coupling layer can deform in coordination with the optical fiber while protecting the optical fiber, and the optical fiber is free of lateral constraints and can move laterally inside the strain coupling layer, thereby ensuring the accuracy of strain sensing optical cable monitoring.

[0031] In one embodiment, the strain sensing optical cable 1 further includes a thermal insulation layer 13, a waterproof layer 14 and an outer protective layer 15; The heat-insulating layer, the waterproof layer and the outer protective layer are sequentially coated on the strain coupling layer.

[0032] Specifically, the thermal insulation layer, the waterproof layer and the outer protective layer are sequentially covered on the strain coupling layer, and the thermal insulation layer, the waterproof layer and the strain coupling layer are inscribed in pairs. It is easy to understand that the strain sensing optical cable is a multi-layer structure, which is optical fiber, strain coupling layer, thermal insulation layer, waterproof layer and outer protective layer from inside to outside. The strain sensing optical cable is hoop-wound and laid on the surface of the corrugated enclosure structure of the cryogenic storage tank as a whole. It is easy to understand that the outer protective layer actually contacts the surface of the corrugated enclosure structure of the cryogenic storage tank.

[0033] Since the ambient temperature of the corrugated enclosure structure of the cryogenic storage tank is extremely low, traditional sensors may fail or work unstably due to low temperature. In the above embodiment, the setting of the insulation layer enables the strain sensing optical cable to work stably in an extremely low temperature environment, solving the problem of traditional sensors failing or working unstably due to low temperature. The setting of the waterproof layer ensures that the external water will not affect the operation of the strain sensing optical cable, and the outer protective layer can prevent physical impact from damaging the strain sensing optical cable to a certain extent.

[0034] In one embodiment, the strain sensing optical cable 1 further comprises a plurality of anchoring clamps 16; The thermal insulation layer, the waterproof layer and the outer protective layer are subjected to a circumferential cutting process at a plurality of the preset bonding points by means of a grooving machine; Each anchoring clamp is fixed to the preset bonding point after the circumcision treatment by adhesive and the metal bite piece of each anchoring clamp.

[0035] Specifically, the strain sensing optical cable also includes a plurality of anchoring clamps. The anchoring clamps are used to fix the optical fiber and the strain coupling layer, so it is necessary to perform a ring cutting process on the thermal insulation layer, the waterproof layer and the outer protective layer outside the strain coupling layer at a plurality of preset bonding points by a grooving machine. It is easy to understand that after the ring cutting process, the preset bonding points no longer include the thermal insulation layer, the waterproof layer and the outer protective layer, but only include the optical fiber and the strain coupling layer. Furthermore, each anchoring clamp can be fixed to the preset bonding point after the ring cutting process by an adhesive and the metal bite parts of each anchoring clamp. Among them, the adhesive can be a low-temperature resistant adhesive, such as low-temperature resistant glue.

[0036] In the above embodiment, each anchoring clamp is fixed to a preset bonding point after the circumcision process by an adhesive and a metal bite piece of each anchoring clamp, which can ensure the coordinated deformation of the anchoring clamp, the optical fiber and the strain coupling layer, thereby improving the accuracy of the acquired strain data.

[0037] In one embodiment, the optical fiber includes a modified polyimide optical fiber or a metal-coated optical fiber; the strain coupling layer includes a metal armor tube, and the metal armor tube adopts a spiral filament structure; the thermal insulation layer includes polyurethane foam or phenolic foam; the waterproof layer includes water-blocking yarn or ointment; the outer protective layer 15 includes a wire mesh 151 and a sheath 152, and the sheath is made of polyetheramine; the anchoring clamp includes a metal bite with ribs.

[0038] Specifically, the optical fiber can be a modified polyimide optical fiber or a metal-coated optical fiber. Among them, the temperature resistance range of the modified polyimide optical fiber is -195 degrees Celsius to 380 degrees Celsius. The strain coupling layer includes a metal armor tube, which adopts a spiral filamentary structure. The metal armor tube can be, for example, a stainless steel spiral wire armor tube. The thermal insulation layer can be made of polyurethane foam, or phenolic foam. Preferably, the thermal insulation layer uses polyurethane foam, which can swell when exposed to water to prevent external water vapor from entering. The waterproof layer can be made of water-blocking yarn, or ointment. Preferably, the waterproof layer uses water-blocking yarn to effectively prevent external water from entering. The outer protective layer includes a wire mesh and a sheath. The sheath is made of polyetheramine (PEA), which is a low-temperature resistant material. Such as Figure 2 As shown, the steel wire mesh is placed between the waterproof layer and the sheath, and this arrangement can increase the tensile strength of the strain sensing optical cable. The metal bite piece of the anchoring clamp has ribs to facilitate the clamping with the strain sensing optical cable.

[0039] In the above embodiments, the specific structure and corresponding materials of each component in the strain sensing optical cable are defined, which can ensure the low temperature resistance, waterproofness and tensile strength of the strain sensing optical cable.

[0040] In one embodiment, the strain data includes strains corresponding to a plurality of positions of the corrugated enclosure structure of the cryogenic storage tank; The data analysis unit is specifically used for: For each of the positions, integrating the strain corresponding to the position to obtain the deformation corresponding to the position; Based on the deformation amounts corresponding to all the positions, a target deformation amount of the corrugated enclosure structure of the cryogenic storage tank is determined.

[0041] Specifically, the strain data includes strains corresponding to multiple positions of the corrugated enclosure structure of the cryogenic storage tank. The data analysis unit can integrate the strain corresponding to each position to obtain the deformation corresponding to the position. The deformation at It can be determined by the following formula: in, Indicates location The corresponding dependent variable.

[0042] Then, the target deformation of the corrugated enclosure structure of the cryogenic storage tank can be determined based on the deformation corresponding to all positions.

[0043] In the above embodiment, the corresponding variables are integrated to obtain the deformation corresponding to each position, and further based on the deformation corresponding to all positions, the target deformation of the corrugated enclosure structure of the cryogenic storage tank can be accurately determined.

[0044] In one embodiment, the data analysis unit is further configured to: Obtaining a finite element model corresponding to the corrugated enclosure structure of the cryogenic storage tank constructed based on a preset finite element analysis software; The target deformation is mapped to the finite element model, and the mapped finite element model is analyzed based on the Hassin failure criterion and the maximum stress criterion to obtain the structural failure state corresponding to the corrugated enclosure structure of the cryogenic storage tank.

[0045] Specifically, the preset finite element analysis software can be set as needed. The embodiment of the present invention does not make specific settings here. For example, the SHELL91 unit in the ANSYS finite element analysis software can be used. The finite element model corresponding to the low-temperature storage tank corrugated enclosure structure can be constructed in advance by the preset finite element analysis software, and then the finite element model can be obtained, and the target deformation can be mapped to the finite element model. The mapped finite element model can be further analyzed based on the Hashin failure criterion and the maximum stress criterion to obtain the structural failure state corresponding to the low-temperature storage tank corrugated enclosure structure. The structural failure state can include whether each layer in the low-temperature storage tank corrugated enclosure structure has failed, and whether the low-temperature storage tank corrugated enclosure structure as a whole has failed.

[0046] Optionally, in order to explore the limit state of the corrugated enclosure structure of the cryogenic storage tank, an internal pressure load can be set to apply pressure to the corrugated enclosure structure of the cryogenic storage tank. When each layer in the corrugated enclosure structure of the cryogenic storage tank fails, the material constant of the failed layer is modified, and the internal pressure load is increased to repeat the above steps until the corrugated enclosure structure of the cryogenic storage tank fails as a whole.

[0047] In the above embodiment, a finite element model corresponding to the corrugated enclosure structure of the cryogenic storage tank is constructed by finite element analysis software, and then the target deformation is mapped to the finite element model. The mapped finite element model is analyzed based on the Hassin failure criterion and the maximum stress criterion, so that the accurate structural failure state corresponding to the corrugated enclosure structure of the cryogenic storage tank can be obtained.

[0048] In one embodiment, the data analysis unit is further configured to: Constructing a three-dimensional visualization model corresponding to the corrugated enclosure structure of the cryogenic storage tank; The strain amounts and / or deformation amounts corresponding to all the positions are displayed on the three-dimensional visualization model.

[0049] Specifically, the data analysis unit can also construct a three-dimensional visualization model corresponding to the corrugated enclosure structure of the cryogenic storage tank, and display the strain and / or deformation corresponding to each position on the three-dimensional visualization model.

[0050] In the above embodiment, the strain and / or deformation corresponding to all positions of the corrugated enclosure structure of the cryogenic storage tank are intuitively displayed through a three-dimensional visualization model, making the data display more intuitive and improving the user experience.

[0051] The deformation monitoring device for the corrugated enclosure structure of a cryogenic storage tank provided by the present invention comprises a strain sensing optical cable and a data analysis unit. The strain sensing optical cable is circumferentially wound and laid on the surface of the corrugated enclosure structure of the cryogenic storage tank; the strain sensing optical cable is used to detect the strain data of the corrugated enclosure structure of the cryogenic storage tank; the data analysis unit is used to obtain the strain data and determine the target deformation of the corrugated enclosure structure of the cryogenic storage tank based on the strain data.

In addition, the accuracy of the data collected by the strain sensing optical cable is also higher than that of traditional sensors, which can meet the demand for real-time monitoring of the deformation of the corrugated enclosure structure of the cryogenic storage tank.

[0052] It should be further explained that the deformation monitoring device of the corrugated enclosure structure of the cryogenic storage tank provided by the present invention adopts a strain sensing optical cable, which has the advantages of wide monitoring range and high accuracy compared with the traditional point measurement methods such as resistance strain gauges and vibrating wire sensors. In addition, the strain sensing optical cable can monitor the strain data in real time without manual intervention, and when maintenance and overhaul are required, the distributed characteristics of the optical cable can be used to quickly locate the problem area, thereby improving the efficiency of maintenance and overhaul.
