Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a rapid classification and detection device for underwater magnetic anomaly data. Background Technology

[0002] Currently, in fields such as marine engineering, military exploration, and geological research, rapid and accurate detection of underwater magnetic anomaly data is crucial for identifying underwater targets and analyzing geological structures. Existing underwater magnetic anomaly detection devices mostly employ fixed installation methods, typically directly fixed to the bottom of the ship's hull or an underwater platform, making it difficult to flexibly adjust the detection depth according to actual detection needs. When encountering targets at different depths, this fixed installation method prevents the detection device from acquiring data from the optimal location, severely impacting the accuracy and effectiveness of the detection results. Furthermore, existing underwater magnetic anomaly detection equipment has a low degree of integration, with functional components such as sensors, data acquisition modules, and controllers scattered throughout, increasing the difficulty of installation and maintenance. At the same time, due to the lack of effective protective measures, factors such as seawater corrosion and water pressure in the underwater environment can damage the core components of the detection device, shortening its service life. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid classification and detection device for underwater magnetic anomaly data. This device, based on the depth of the target, activates a waterproof electric push rod, which in turn moves the mounting plate, protective box, and internal magnetic sensor, data acquisition module, controller, storage module, and communication module up and down, allowing the magnetic sensor to reach a suitable detection depth to obtain more accurate underwater magnetic anomaly data.

[0004] The objective of this utility model is achieved through the following technical solution: A rapid classification and detection device for underwater magnetic anomaly data includes a base plate, a lifting assembly connected above the base plate, a protective box connected above the lifting assembly, and a magnetic sensor, a data acquisition module, a controller, a storage module, and a communication module fixedly installed inside the protective box by bolts.

[0005] As a further description of the above technical solution: The lifting assembly includes a waterproof electric push rod fixed to the top surface of the base plate by bolts. The free end of the waterproof electric push rod is fixed to a mounting plate by bolts. The protective box is fixed above the mounting plate by bolts. Guide rods are welded to both sides of the top surface of the base plate. The top ends of the two guide rods slide through the mounting plate and extend above the mounting plate.

[0006] As a further description of the above technical solution: Guide holes are provided on both sides of the mounting plate, and the two guide rods are slidably connected in the two guide holes respectively.

[0007] As a further description of the above technical solution: The magnetic sensor is typically connected to the data acquisition module via an analog signal line. The data acquisition module is connected to the controller via a data bus. The controller is connected to the storage module via a storage interface and to the communication module via a communication interface.

[0008] As a further description of the above technical solution: Mounting holes are provided at all four corners of the base plate.

[0009] As a further description of the above technical solution: The front of the protective box is fixed with a door by bolts, and a rubber pad is affixed to the side of the door closest to the protective box.

[0010] As a further description of the above technical solution: One side of the rubber pad is in close contact with the protective box.

[0011] This utility model has the following beneficial effects: 1. Based on the depth of the target being detected, this utility model activates a waterproof electric push rod, which in turn moves the mounting plate, protective box, and internal magnetic sensor, data acquisition module, controller, storage module, and communication module up and down, allowing the magnetic sensor to reach a suitable detection depth to obtain more accurate underwater magnetic anomaly data.

[0012] 2. The magnetic sensor of this utility model senses abnormal changes in the underwater magnetic field in real time and converts the physical signal into an electrical signal output. The data acquisition module receives the electrical signal, and after amplification, filtering and other preprocessing, converts the analog signal into a digital signal and acquires it according to a specific frequency and format, and then transmits it to the controller. The controller compares it with existing magnetic anomaly characteristic data, identifies and classifies the underwater magnetic anomaly source. During data processing, the storage module temporarily stores the original data and classification results for review and analysis. The communication module transmits the effective data to the ship's receiving terminal in real time. In addition, the protective box and box door protect the internal electronic components, resist underwater corrosion and water pressure, and ensure the stable operation of each module.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 One embodiment of this utility model includes a base plate 1, a lifting assembly connected above the base plate 1, a protective box 6 connected above the lifting assembly, and a magnetic sensor 8, a data acquisition module 9, a controller 10, a storage module 11, and a communication module 12 fixedly installed inside the protective box 6 by bolts.

[0017] The lifting assembly includes a waterproof electric push rod 2 bolted to the top surface of the base plate 1. The free end of the waterproof electric push rod 2 is bolted to a mounting plate 3. A protective box 6 is bolted to the top of the mounting plate 3. Guide rods 4 are welded to both sides of the top surface of the base plate 1. The top ends of both guide rods 4 slide through the mounting plate 3 and extend above it. Guide holes 13 are provided on both sides of the mounting plate 3. The two guide rods 4 are slidably connected in the two guide holes 13. The guide rods 4 cooperate with the guide holes 13 to guide and limit the lifting movement of the mounting plate 3, preventing the mounting plate 3 from shifting or shaking during lifting, thus improving the stability and reliability of the lifting process. The magnetic sensor 8 is typically connected to the data acquisition module 9 via an analog signal line. The data acquisition module 9 is connected to the controller 10 via a data bus. The controller 10 is connected to the storage module 11 via a storage interface and to the communication module 12 via a communication interface. The communication module 12 communicates with the receiving terminal or remote control center on the hull. Mounting holes 7 are provided at the four corners of the bottom plate 1. The front of the protective box 6 is fixed with a box door 5 by bolts. A rubber gasket is bonded to the side of the box door 5 near the protective box 6. The side of the rubber gasket is in close contact with the protective box 6, which enhances the sealing performance of the protective box 6 and effectively resists seawater erosion and water pressure impact in the underwater environment.

[0018] The working principle of this utility model is as follows: The device is securely installed on the bottom of the hull using bolts through the mounting holes 7 at the four corners of the base plate 1, providing reliable support for subsequent operations. When underwater magnetic anomaly detection is required, the operator activates the waterproof electric push rod 2 according to the target depth. This causes the waterproof electric push rod 2 to raise and lower the mounting plate 3, the protective box 6, and the internal magnetic sensor 8, data acquisition module 9, controller 10, storage module 11, and communication module 12, so that the magnetic sensor 8 reaches the appropriate detection depth to obtain more accurate underwater magnetic anomaly data.

[0019] As the core component of data acquisition, the magnetic sensor 8 can sense abnormal changes in the underwater magnetic field in real time and convert physical signals such as magnetic field strength and direction into electrical signals for output. The data acquisition module 9 is responsible for receiving the electrical signals output by the magnetic sensor 8, amplifying and filtering them, converting the analog signals into digital signals, and acquiring them according to a certain sampling frequency and format. The acquired data is transmitted to the controller 10. The controller 10 has built-in data processing algorithms and classification models, which can quickly analyze and process the received data. By comparing the data with existing magnetic anomaly feature data in the database, it identifies and classifies underwater magnetic anomaly sources and determines whether they are target objects.

[0020] During data processing, the storage module 11 temporarily stores the collected raw data and the classification results data processed by the controller 10, facilitating subsequent data review and analysis. Simultaneously, the communication module 12 transmits the processed valid data to the receiving terminal on the ship in real time, enabling operators to promptly grasp underwater magnetic anomalies and make appropriate decisions. Throughout the entire workflow, the protective box 6 and the box door 5 provide protection for the internal electronic components, resisting adverse factors such as seawater erosion and water pressure impact in the underwater environment, ensuring the stable operation of each module, thereby achieving rapid and accurate classification and detection of underwater magnetic anomaly data.

[0021] All electrical components in this invention are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. The detailed description of known functions and components is omitted in the specific embodiments of this invention. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
