Description

Technical Field

[0001] This invention relates to the field of biomass measurement technology, and in particular to a krill biomass estimation device based on dynamic correction of echo intensity and depth. Background Technology

[0002] Antarctic krill biomass estimation plays a crucial role in marine resource management. Traditional estimation methods, such as the zooplankton dry weight method, the productivity-to-biomass ratio conversion method, and net sampling, each have their limitations. With technological advancements, acoustic methods have become a popular choice due to their high efficiency. A krill biomass estimation device based on dynamic correction of echo intensity and depth utilizes acoustic technology to conduct on-site measurements at sea by analyzing krill target intensity model parameters. This device can extract krill signals from acoustic data and calculate the acoustic reflection coefficient per square nautical mile. The advantage of this estimation device lies in its ability to dynamically correct echo intensity and depth, improving the accuracy of resource assessment and providing a scientific basis for the development and management of krill biological resources. Through continuous improvement and refinement, this device has broad application prospects in Antarctic krill biomass estimation, contributing to the conservation and sustainable utilization of Antarctic krill resources.

[0003] However, in common ship biomass measurement devices, the measuring device will swing with the hull movement, resulting in inaccurate measurement data. In addition, the measuring device is exposed to seawater corrosion for a long time, resulting in a short service life. Utility Model Content

A sonar telescopic hole 2 is provided at the bottom of the hull 1. A sonar detector 3 is slidably connected to the inner side of the sonar telescopic hole 2. A gyroscope stabilizing ring 4 is fixedly connected above the sonar detector 3. A gyroscope stabilizing ring 3 connecting post 5 is fixedly connected to the inner side of the gyroscope stabilizing ring 4. A gyroscope stabilizing ring 6 is rotatably connected to the inner side of the gyroscope stabilizing ring 6. A central connecting post 7 is fixedly connected to the inner side of the gyroscope stabilizing ring 6. A gyroscope motor 8 is fixedly connected to the outer side of the central connecting post 7. A gyroscope rotating wheel 9 is rotatably connected to the outer side of the gyroscope motor 8, thereby improving the accuracy of krill biomass estimation.

[0041] Reference Figure 1-6 During equipment operation, the lifting motor 19 is activated via the operation button 23 on the control panel 21. The lifting motor 19 drives the lifting screw 12 to rotate, which in turn drives the screw sliding ring 20 to rise and fall. This controls the extension and retraction of the sonar detector 3 within the sonar telescopic hole 2. The sonar detector 3 can be retracted to prevent long-term seawater erosion and damage from running aground, thus extending the service life of the equipment. During equipment operation, the ship is subjected to the impact of wind and waves, causing it to sway. The gyroscope motor 8 is activated, which drives the gyroscope rotating wheel 9 to rotate, generating centrifugal force. This ensures that the sonar detector 3, which is fixedly connected to the outside of the gyroscope stabilizing ring 4, remains horizontal, thus ensuring the accuracy of krill biomass estimation.

[0042] Reference Figure 1-6 The outer side of the gyroscope stabilizing ring 6 is rotatably connected to the gyroscope stabilizing ring 2 connecting post 13. The outer side of the gyroscope stabilizing ring 2 connecting post 13 is fixedly connected to the gyroscope stabilizing ring 10. The outer side of the gyroscope stabilizing ring 10 is fixedly connected to the gyroscope stabilizing ring 11. This ensures the sonar detector 3 remains stable and vertical even when the hull sways back and forth.

[0043] Reference Figure 1-3 A lifting motor 19 is fixedly connected to the top of the bottom of the hull 1. A lifting screw 12 is rotatably connected above the lifting motor 19. A screw sliding ring 20 is slidably connected to the outer side of the lifting screw 12. A gyroscope stabilizing ring connecting column 11 is rotatably connected to the inner side of the screw sliding ring 20. This can drive the sonar detector 3 to retract and extend, improving the service life of the sonar detector 3.

[0044] Reference Figure 1-3 A stabilizing column 15 is fixedly connected to the bottom of the hull 1. A stabilizing column sliding ring 14 is slidably connected to the outside of the stabilizing column 15. A gyroscope stabilizing ring connecting column 11 is rotatably connected to the inside of the stabilizing column sliding ring 14. This ensures that the equipment remains stable during lifting and lowering.

[0045] Reference Figure 1-3 The lifting screw 12 and the stabilizing column 15 are respectively fixedly connected with screw anti-disengagement cap 16 and stabilizing column anti-disengagement cap 17. This ensures the equipment will not detach and guarantees normal operation.

[0046] Reference Figure 1 A microcomputer processor 18 is fixedly connected to the top of the hull 1. It can estimate the krill biomass in the signal transmitted by the sonar detector 3.

[0047] Reference Figure 1 An operation panel 21 is fixedly connected to the top of the hull 1. A display screen 22, operation buttons 23, and a steering wheel 24 are fixedly connected to the top of the operation panel 21. This allows for convenient operation of the equipment.

[0048] Reference Figure 1 A protective cover 25 is fixed to the bottom of the hull 1, and a gyroscope is fixedly connected inside the protective cover 25. This protects the lifting and gyroscope devices from seawater corrosion.

[0049] The implementation principle of the krill biomass estimation device based on dynamic correction of echo intensity and depth in this application is as follows:

[0050] During equipment operation, the lifting motor 19 is activated via the operation button 23 on the control panel 21. The lifting motor 19 drives the lifting screw 12 to rotate, which in turn drives the screw sliding ring 20 to rise and fall. This controls the extension and retraction of the sonar detector 3 within the sonar telescopic hole 2. The sonar detector 3 can be retracted to prevent long-term seawater erosion and damage from running aground, thus extending the equipment's service life. During equipment operation, the ship may be impacted by wind and waves and sway. In this case, the gyroscope motor 8 is activated, which drives the gyroscope rotating wheel 9 to rotate, generating centrifugal force. This ensures that the sonar detector 3, which is fixedly connected to the outside of the gyroscope stabilizing ring 4, remains horizontal, thus ensuring the accuracy of krill biomass estimation.

[0051] In summary, during the operation of this utility model, the lifting motor is activated via the operation buttons on the control panel. The lifting motor drives the lifting screw to rotate, which in turn causes the screw sliding ring to rise and fall. This allows control of the sonar detector's extension and retraction within the sonar telescopic hole. The sonar detector can be retracted to prevent long-term seawater erosion and damage from reefs, thus extending the equipment's lifespan. During operation, if the vessel is subjected to wind and waves and sways, the gyroscope motor is activated. This motor drives the gyroscope rotating wheel to rotate, generating centrifugal force. This ensures the sonar detector, which is fixedly connected to the outer side of the gyroscope stabilizing ring, remains horizontal, guaranteeing the accuracy of krill biomass estimation.
