Description

Technical Field

[0001] This utility model relates to the field of marine mooring equipment technology, specifically to an R6-class mooring monitoring system. Background Technology

[0002] With the surge in the use of marine equipment such as floating wind turbines and net cages, the demand for mooring equipment is also gradually increasing. In severe marine environments such as typhoons, the requirements for the performance, lifespan, quality, and reliability of mooring equipment increase dramatically. Therefore, real-time monitoring of the usage of mooring equipment and ensuring data accuracy are crucial.

[0003] Traditional mooring chain management methods in existing technologies typically rely on manual monitoring and adjustment, which are easily affected by environmental factors such as severe weather. This makes it impossible to monitor and adjust the stress on the mooring chain in real time, posing safety hazards. With the development of intelligent systems, various sensors have been installed to manage the mooring chain and a monitoring and management system has been established. However, the main spoke-type force sensors rely on deformation sensing resistors to output signals to measure force. When the force sensor deforms under force, a gap is generated between it and the object being measured, and the installation environment can easily affect the measurement accuracy of the sensor, thus easily affecting the safety of the monitoring system and hindering real-time and accurate monitoring in complex environments. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the installation of force sensors in the prior art, thereby providing an R6-level mooring monitoring system.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An R6-class mooring monitoring system includes an offshore floating platform, mooring equipment, and a control center. The control center is located on the offshore floating platform, and the mooring equipment is installed on the sidewall of the offshore floating platform. The control center is connected to the mooring equipment via signal control. The mooring equipment includes a base frame, a mooring structure, and a main shaft. The main shaft connects the base frame and the mooring structure, and the mooring structure is rotatably mounted on the base frame via the main shaft. The base frame is equipped with monitoring sensors for detecting ambient temperature and humidity. The main shaft includes a force-measuring pin and two force sensors. The mooring structure is equipped with a position sensor. The monitoring sensors, force sensors, and position sensors are all connected to the control center for communication feedback.

[0007] By adopting the above technical solution, data is collected using monitoring sensors, force sensors, and position sensors to realize the monitoring function of mooring equipment. The collected data is sent to the control center for analysis and processing, and then displayed intuitively to realize the analysis of working conditions and ensure working safety.

[0008] Furthermore, the force sensor is installed at opposite ends of the force-measuring pin shaft. The force sensor and the force-measuring pin shaft are connected by multiple fixing bolts. The fixing bolts are arranged in a circumferential array along the force-measuring pin shaft, and the axis of the fixing bolts is parallel to the axial direction of the force-measuring pin shaft. The outer diameter of the force sensor is not greater than the diameter of the force-measuring pin shaft.

[0009] By adopting the above technical solution, the force sensor is symmetrically installed on the force measuring pin and fixed with a nut to ensure that the two ends of the force measuring pin are symmetrical and balanced. Furthermore, the accurate measurement of the main shaft parts is achieved by measuring the force at both ends twice, thus ensuring the accuracy of the data.

[0010] Furthermore, the force sensor includes an integrally formed mounting ring, a force-bearing ring, and a strain gauge. The mounting ring and the force-bearing ring are both circular and coaxially arranged. The mounting ring is sleeved outside the force-bearing ring, and the strain gauge is fixed between the mounting ring and the force-bearing ring. The axial length of the strain gauge is less than the axial length of the mounting ring. The end of the force-bearing ring near the force-measuring pin shaft has an extension ring that is installed and connected to the force-measuring pin shaft.

[0011] By adopting the above technical solution, the force-bearing ring contacts the force-measuring pin shaft, and the deformation is transferred to the strain when in contact. Finally, the corresponding data is measured and transmitted to the control center to achieve the purpose of force measurement.

[0012] Furthermore, a mounting retaining ring extends from the outer periphery of the mounting ring near the force measuring pin shaft, and a mounting shaft collar extends from the force measuring pin shaft corresponding to the mounting retaining ring. The mounting retaining ring and the mounting shaft collar are engaged. The mounting ring also has several mounting holes extending through it circumferentially, and the mounting holes are corresponding to the fixing bolts.

[0013] By adopting the above technical solution, the mounting ring and the mounting shaft ring are engaged to achieve a sealing at the mounting ring and the force measuring pin shaft, which increases the distance between the internal strain element and the water vapor, and reduces the risk of the force sensor being affected by external conditions.

[0014] Furthermore, both ends of the mounting ring have shielding rings extending towards the center. The shielding rings are fixed inside both ends of the mounting ring and are located close to the force-bearing ring. The inner diameter of the shielding ring is larger than the outer diameter of the force-bearing ring.

[0015] By adopting the above technical solution, the shielding ring shields part of the strain without contacting the stressed body, thus playing a certain role in blocking dust and moisture and protecting the strain.

[0016] Furthermore, the mooring structure is also equipped with protective components corresponding to the force sensor. The protective components are disposed opposite to the two ends of the force-measuring pin and are fixed to the mooring structure. The protective components include a protective cover, a positioning ring, and a cable protection cylinder. The protective cover is coaxially disposed with the force-measuring pin and is installed on the mooring structure. The positioning ring is coaxially disposed with the protective cover and is threadedly connected to the protective cover. The cable protection cylinder is axially perpendicular to the protective cover and is threadedly connected to the top of the protective cover.

[0017] By adopting the above technical solution, protective components are set to further protect the force sensors of the main shaft parts, providing a guarantee for the operation of the force sensors; the end of the positioning ring abuts against the mounting ring of the force sensor, which can be adapted to the spoke-type force sensor, or a smaller diameter positioning ring can be replaced to adapt to the pin-type force sensor.

[0018] Furthermore, a sealing ring is provided inside the top of the cable protection cylinder, and a wire-passing hole is vertically provided inside the sealing ring. A sealing groove is provided circumferentially on the inner side wall of the sealing ring.

[0019] By adopting the above technical solution, the sealing ring protects the cable extending from the force sensor and also prevents moisture from corroding the force sensor from the cable.

[0020] Furthermore, the mooring structure also includes a drive unit and a stop unit, both of which are connected to the control center via signal control. The control center is communicatively connected to a host computer, which is communicatively connected to a data processing unit, which is communicatively connected to a display platform.

[0021] By adopting the above technical solution, the monitoring sensor monitors the temperature and humidity of the working environment in real time, the force sensor monitors the force at the force pin, and the displacement sensor monitors the displacement and tension of the mooring mechanism. The collected information is fed back to the PLC control center. The relevant information enters the host computer and is processed, analyzed and stored by the data processing unit. The processed and analyzed structure is displayed on the display platform, and the drive and stop components are controlled to perform corresponding operations based on past information or manually set conditions.

[0022] In summary, the technical solution of this utility model has the following advantages:

[0023] 1. The R6-level mooring monitoring system provided by this utility model aims to achieve automated monitoring of mooring equipment, monitor operating conditions and equipment usage in real time, and realize functions such as overload alarm and early warning. It also performs real-time analysis and display of equipment usage, intuitively displays data information, and reduces labor costs.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0033] An R6-level mooring monitoring system, such as Figure 1 As shown, the system includes a floating platform 1, mooring equipment 2, and a control center 6. The control center 6 is mounted on the floating platform 1, and the mooring equipment 2 is mounted on the side wall of the floating platform 1 near the bottom. The control center 6 is connected to the mooring equipment 2 via signal control. The mooring equipment 2 includes a base frame 3, a mooring structure 4, and a main shaft 5. The main shaft 5 connects the base frame 3 and the mooring structure 4, and the mooring structure 4 is rotatably mounted on the base frame 3 via the main shaft 5. The mooring structure 4 can be a chain guide, chain stop, or other marine mooring structure. The mooring structure 4 also includes a drive component 43 and a stop component 44, both of which are connected to the control center 6 via signal control.

[0034] The base frame 3 is equipped with a monitoring sensor 31 for detecting ambient temperature and humidity. The main shaft 5 includes a force measuring pin 51 and two force measuring sensors 52. The mooring structure 4 is equipped with a position sensor 41. The monitoring sensor 31, the force measuring sensor 52 and the position sensor 41 are all connected to the control center 6 for communication feedback.

[0035] The control center 6 is connected to a host computer 7, which in turn is connected to a data processing unit 8. The data processing unit 8 is also connected to a display platform 9. Monitoring sensors 31 monitor the temperature and humidity of the working environment in real time. Force sensors 52 monitor the force at the force-measuring pin 51, and displacement sensors monitor the displacement and tension of the mooring mechanism. The collected information is fed back to the PLC control center 6. This information enters the host computer 7 and is processed, analyzed, and stored by the data processing unit 8. The processed and analyzed data is displayed on the display platform 9, which shows the force conditions, working environment, and operating status. Based on past information or manually set conditions, the platform controls the drive unit 43 and the stop unit 44 to perform corresponding operations. The data processing unit 8 in the host computer 7 can store historical records, maintenance information, energy consumption information, etc., for analysis and processing to provide optimization suggestions.

[0036] like Figure 1 and Figure 2 As shown, force sensors 52 are installed at opposite ends of force-measuring pins 51, and the outer diameter of force sensors 52 is no larger than the diameter of force-measuring pins 51. Force sensors 52 are symmetrically installed on force-measuring pins 51 and fixed with nuts to ensure symmetrical balance at both ends of the force-measuring pins 51. Accurate measurement of key shaft components is achieved through two force measurements at both ends, ensuring data accuracy.

[0037] A protective element 42 is also provided on the mooring structure 4 corresponding to the force sensor 52. The protective element 42 is positioned opposite to both ends of the force-measuring pin 51 and is fixedly installed on the mooring structure 4. The protective element 42 further protects the force sensor 52, which is a main shaft component, and provides protection for the operation of the force sensor 52. The protective element 42 includes a protective cover 421, a positioning ring 422, and a cable protection sleeve 423. The protective cover 421 is coaxially arranged with the force-measuring pin 51 and installed on the mooring structure 4. The positioning ring 422 is coaxially arranged with the protective cover 421 and threadedly connected to be installed inside the protective cover 421. The cable protection sleeve 423 is axially perpendicular to the protective cover 421 and threadedly connected to be installed on the top outer side of the protective cover 421. The end of the positioning ring 422 abuts against the mounting ring 521 of the force sensor 52. It can be adapted to a spoke-type force sensor 52, or a smaller diameter positioning ring 422 can be replaced to adapt to a pin-type force sensor 52.

[0038] like Figure 2 and Figure 3 As shown, a sealing ring 4231 is provided inside the top of the cable protection cylinder 423. A wire-passing hole 4232 is vertically provided inside the sealing ring 4231, and a sealing groove 4233 is provided circumferentially on the inner side wall of the sealing ring 4231. The sealing ring 4231 protects the cable extending from the force sensor 52 and also prevents moisture from corroding the force sensor 52 from the cable.

[0039] like Figure 2 and Figure 3 As shown, the force sensor 52 includes an integrally formed mounting ring 521, a force-bearing ring 522, and a strain gauge 523. The force-bearing ring 522 contacts the force-measuring pin 51, and transmits deformation to the strain gauge 523 upon contact. Finally, the corresponding data is measured and transmitted to the control center 6 to achieve the purpose of force measurement. Both the mounting ring 521 and the force-bearing ring 522 are circular and coaxially arranged. The mounting ring 521 is sleeved on the outside of the force-bearing ring 522, and the strain gauge 523 is fixed between the mounting ring 521 and the force-bearing ring 522. The axial length of the strain gauge 523 is less than the axial length of the mounting ring 521. An extension ring 5221 extends from the end of the force-bearing ring 522 near the force-measuring pin 51 and is installed and connected to the force-measuring pin 51.

[0040] A mounting retaining ring 5211 extends from the outer periphery of the mounting ring 521 near the force-measuring pin 51. A mounting collar 512 extends from the force-measuring pin 51 corresponding to the mounting retaining ring 5211. The mounting retaining ring 5211 and the mounting collar 512 are engaged. This engagement of the mounting retaining ring 5211 and the mounting collar 512 achieves a sealing connection between the mounting ring 521 and the force-measuring pin 51, increasing the distance between the internal strain gauge 523 and moisture, and reducing the risk of the force sensor 52 being affected by external conditions. Both ends of the mounting ring 521 have shielding rings 5213 extending towards the center. The shielding rings 5213 are fixed inside both ends of the mounting ring 521 and are positioned close to the force-bearing ring 522. The inner diameter of the shielding rings 5213 is larger than the outer diameter of the force-bearing ring 522. The shielding rings 5213 shield a portion of the strain gauge 523 but do not contact the force-bearing body, thus serving to some extent to prevent dust and moisture from entering and protect the strain gauge 523.

[0041] The force sensor 52 is connected to the force-measuring pin 51 by multiple fixing bolts 511. The fixing bolts 511 are arranged in a circumferential array along the force-measuring pin 51, and the axis of the fixing bolts 511 is parallel to the axial direction of the force-measuring pin 51. The mounting ring 521 also has several mounting holes 5212 that are circumferentially through it, and the mounting holes 5212 are correspondingly arranged with the fixing bolts 511. The fixing bolts 511 fix the force sensor 52 and the force-measuring pin 51.

[0042] The working principle and usage of this R6-level mooring monitoring system are as follows: The control center 6 controls the opening and closing of the drive component 43 and the stop component 44, and pre-stores the threshold values ​​of sensors such as the detection sensor, force sensor 52, and displacement sensor in the data processing unit 8. When the mooring equipment 2 is working, the monitoring sensor 31 monitors the temperature and humidity of the working environment in real time, the force sensor 52 monitors the force at the force pin 51, and the displacement sensor monitors the displacement and tension of the mooring mechanism and other working information. The collected information is fed back to the PLC control center 6, and the relevant information enters the host computer 7 and is processed, analyzed, and stored by the data processing unit 8. The processed and analyzed structure is displayed on the display platform 9. The data processing unit 8 automatically operates the drive component 43 and the stop component 44 according to the relevant information to ensure the safety and stability of the offshore floating platform 1.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
