Figure 2-6As shown, according to an embodiment of the utility model, a device for monitoring the reset state of a cable-release hook is applied to any system for monitoring the reset state of a cable-release hook, and the device comprises: a follower bracket 1, the follower bracket 1 is connected to a limit bracket 10 on the cable-release hook;

[0053] A sensor bracket 2 is arranged on the follow-up bracket 1 , and an angle sensor 3 is arranged inside the sensor bracket 2 .

[0054] In this embodiment, the device for monitoring the reset state of the cable hook includes a dynamic bracket 1. The follower bracket 1 is a core component and is tightly connected to the limit bracket 10 on the cable hook to ensure that it can move synchronously with the rotation of the limit bracket 10; the sensor bracket 2 is firmly installed on the follower bracket 1, providing a stable installation platform for the angle sensor 3; the angle sensor 3 is located inside the sensor bracket 2, and by accurately measuring the rotation angle of the follower bracket 1 (and the limit bracket 10 connected thereto), real-time monitoring of the reset state of the cable hook is achieved.

[0055] The utility model realizes accurate monitoring of the resetting state of the cable-release hook, thereby improving the reliability and safety of the system.

[0056] According to an embodiment of the present utility model, the follower bracket 1 is U-shaped, one end of the follower bracket 1 is sleeved and fixedly connected to the limit bracket 10, and the other end of the follower bracket 1 is fixed with the sensor bracket 2.

[0057] In this embodiment, the follower bracket 1 is U-shaped, and an arc-shaped second fixing mechanism 12 and an arc-shaped first fixing mechanism 11 are provided at one end of the follower bracket 1. The second fixing mechanism 12 is fixedly connected to the main body of the follower bracket 1, and the first fixing mechanism 11 and the second fixing mechanism 12 are fixedly connected by fixing bolts 13; after the connection, a circular space is formed between the first fixing mechanism 11 and the second fixing mechanism 12, which can accommodate the passage of the limit bracket 10. The size of the space can be adjusted by adjusting the fixing bolts 13, so as to realize the sleeve-fixed connection between the follower bracket 1 and the limit bracket 10. A sensor bracket 2 is fixed to the other end of the follower bracket 1.

[0058] The follower bracket 1 is designed as a U-shaped structure, one end of which is fixed to the limit bracket 10 through an adjustable arc-shaped first fixing mechanism 11 and a second fixing mechanism 12 to form a tight connection; the other end is firmly fixed with a sensor bracket 2, and an angle sensor 3 is installed inside the sensor bracket 2 for monitoring the rotation of the follower bracket 1 and the limit bracket 10.

[0059] The utility model realizes flexible sleeve fixation of the follow-up bracket and the limit bracket through the design of the U-shaped follow-up bracket and the adjustable fixing mechanism, while ensuring the accurate installation and monitoring of the angle sensor, and improving the accuracy and convenience of the reset state monitoring of the cable hook.

[0060] According to an implementation mode of the present invention, the sensor bracket 2 is made of brass, and the angle sensor 3 is made of a hard aluminum alloy material for its shell.

[0061] In this embodiment, the sensor bracket 2 is made of brass; brass has good corrosion resistance, good mechanical properties and good processability. The sensor bracket 2 made of brass can resist erosion by harsh environmental factors such as moisture and salt, thereby extending the service life of the sensor bracket 2 and ensuring long-term stable operation.

[0062] Preferably, in this embodiment, the angle sensor 3 is a non-contact Hall element angle sensor, such as Figure 6 As shown, the angle sensor 3 includes an electronic signal sensing chamber 31 and an inductive magnetic head 32. The non-contact Hall element angle sensor detects angle changes through the interaction between the magnetic field and the Hall element. When the inductive magnetic head 32 rotates with the follower bracket 1 (and then with the limit bracket 10), the magnetic field changes it generates are sensed by the Hall element in the electronic signal sensing chamber 31. Since there is no physical contact during the measurement process, wear and friction are reduced, and the service life and reliability of the sensor are improved. The Hall element has high sensitivity and accuracy, and can accurately sense tiny magnetic field changes and convert them into electrical signals for output. This enables the angle sensor 3 to provide high-precision angle measurement data, providing a reliable basis for monitoring the reset state of the cable hook. At the same time, the non-contact measurement method also reduces the measurement error caused by wear or looseness of mechanical parts, and improves the overall stability of the system. The Hall element itself has a certain anti-interference ability and can resist interference from external electromagnetic fields. In addition, the design of the electronic signal sensing chamber 31 and the inductive magnetic head 32 may also take additional shielding measures to further reduce the impact of external interference on the measurement results. This enables the angle sensor 3 to maintain stable measurement performance even in complex industrial environments.

[0063] The angle sensor 3 uses a hard aluminum alloy material to make the shell. The hard aluminum alloy material is not only light and strong, but can also better protect the angle sensor 3, and can also reduce the impact of external electromagnetic interference on the angle sensor 3, ensuring the accuracy and reliability of the measurement data, and further enhancing the anti-interference and durability of the angle sensor 3.

[0064] The utility model effectively improves the durability, accuracy and stability of the cable hook reset status monitoring system; the corrosion resistance and mechanical properties of the brass bracket ensure long-term stable operation, while the combination of the hard aluminum alloy shell and the non-contact Hall element reduces wear, improves measurement accuracy, and enhances anti-interference ability, providing reliable guarantee for accurate monitoring in complex industrial environments.

[0065] Embodiment 3

[0066] A system for monitoring the reset state of a cable-release hook comprises a device for monitoring the reset state of the cable-release hook, wherein the device uses an angle sensor 3 of a contactless Hall element, the angle sensor 3 detects the rotation angle of a limit bracket, converts an RS485 signal transmitted by the angle sensor 3 into a Modbus signal through data acquisition, performs data analysis and comparison through a background program, confirms the comparison between the actual rotation angle and the reset angle, and controls an audible and visual alarm to sound through a DO point on a data acquisition card (the DO point is a common negative output, the output is 1, the negative pole is connected, and the alarm is activated, otherwise it is blocked and the alarm is not activated).

[0067] The utility model adds an instrument detection link in the resetting process of the cable hook, which greatly reduces the probability of personnel not fully resetting, avoids the cable hook from accidentally being unhooked when the ship tightens the cable tension and the ship generates a large offshore force due to the influence of ocean currents and gusts, and improves the safety of the cable hook.

[0068] The utility model uses an angle sensor with a non-contact Hall element to ensure the detection accuracy of the resetting condition of the cable hook. The sensor uses a hard aluminum alloy material to make the shell with a protection level of IP68 to avoid sensor accuracy reduction or failure due to seaside corrosion, mechanical wear, etc., thereby improving the reliability of the system and the device.

[0069] Working principle:

[0070] 1. Install the angle sensor 3. The specific process is as follows:

[0071] 1. Remove the roller limit bracket 10 and grind the limit bracket 10 on the bayonet connection side;

[0072] 2. Reinstall the roller limit bracket 10 and fix the follower bracket 1 of the angle sensor permanent magnet module with two bolts;

[0073] 3. Use two nuts to fix the sensor electronic signal sensing bin copper sleeve (sensor bracket 2);

[0074] 4. Install the electronic signal sensing chamber 31 into the copper sleeve and tighten it with 1 bolt;

[0075] 5. Use 1 bolt to fix the permanent magnet module in the installation copper sleeve;

[0076] 6. Use two bolts to fix the permanent magnet copper sleeve on the follower bracket, and adjust the connecting bolts between the permanent magnet copper sleeve and the bracket to calibrate the concentric rotation of the permanent magnet module;

[0077] 2. Adjust the angle comparison procedure to monitor the reset status of the cable hook:

[0078] 1. The induction head senses the Hall effect of the permanent magnet and outputs an RS485 signal from the electronic signal sensing compartment;

[0079] 2. The data acquisition module sends the data to the data transmission module, which sends the data to the data analysis module. The data analysis module converts the received RS485 signal into a Modbus protocol signal, obtains the angle value through program analysis, adjusts the angle of the permanent magnet module, and places the permanent magnet motion trajectory within the working range of the induction head (within the range of 0-90°);

[0080] 3. Confirm through program comparison whether to give an alarm output to the DO point of the data acquisition module. When an alarm output is required, the data analysis module sends information to the alarm module, and the sound and light alarm of the alarm module works through the 24V voltage input to give an alarm.

[0081] The utility model installs an angle sensor on a roller limit bracket through a follow-up bracket, and monitors the angle of the limit bracket through the concentric movement of the sensor induction head and the limit bracket; the sensor electronic signal bin outputs an RS485 signal by monitoring the magnetic field change (rotation angle) of the induction head, and the data acquisition card converts the RS485 signal into a Modbus protocol signal, and obtains a specific angle value through decoding by a computer-side program, and compares the angle value of the reset state during the installation test. If the difference between the test value and the reset value is greater than 1, the DO port of the data acquisition card outputs a 24V voltage, controls the relay to be attracted, and sends out an audible and visual alarm signal; if the difference is less than 1, the DO port of the data acquisition card outputs a 0V voltage, the relay loses power and is disconnected, and the audible and visual alarm disappears.

[0082] The utility model integrates instrument detection link in the resetting process of the cable-release hook, realizes accurate monitoring of the resetting state, and greatly reduces the risk of incomplete resetting due to human negligence; it effectively prevents the ship from accidentally unhooking due to the strong offshore force generated by the impact of ocean currents or gusts when the cable-release hook is not completely reset during the cable tightening process, thereby ensuring the safety and stability of the operation site.

[0083] The utility model adopts an angle sensor with a non-contact Hall element, which not only ensures the accurate detection of the reset of the cable hook, but also significantly improves the durability and environmental adaptability of the sensor by selecting hard aluminum alloy material as the sensor housing and reaching the IP68 waterproof and dustproof standard. It effectively resists the erosion of the harsh seaside environment, such as salt spray corrosion, moisture, and mechanical wear and other potential threats, ensures the long-term stable operation of the sensor, avoids safety hazards caused by reduced accuracy or failure, and further enhances the reliability and stability of the entire system.
