Abstract
Description
Technical Field
[0001] This utility model is an impact-resistant underwater detection device, belonging to the technical field of underwater detection equipment. Background Technology
[0002] Underwater detection devices are equipment used for underwater environmental monitoring and data acquisition, and are widely used in marine scientific research, underwater resource exploration, and underwater engineering inspection. These devices are typically equipped with various sensors and cameras to acquire data such as images, sound, temperature, and pressure of the underwater environment.
[0003] Existing underwater detection devices are mainly used to collect data on marine life, geology, and hydrology; explore seabed mineral resources, oil and gas resources, and renewable energy; and inspect the structural safety of underwater facilities such as bridges, pipelines, and dams.
[0004] While existing underwater detection devices perform well in a variety of underwater environments, some problems still exist under certain conditions, especially in reef areas:
[0005] When the device is conducting exploration in a reef area, it is prone to impact with the reef if it encounters external forces such as underwater currents, rapids, or collisions with large fish. The camera lens is one of the key components of the underwater exploration device, but it is easily damaged when it encounters impacts, affecting the accuracy and continuity of data acquisition.
[0006] Therefore, the purpose of this study is to design an underwater detection device that can be applied in environments with dense reefs and rapid currents, and that has reliability, applicability, and stronger impact resistance. Utility Model Content
[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact-resistant underwater detection device to solve the problems of the existing technology.
[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0009] An impact-resistant underwater detection device, comprising:
[0010] The rigid component includes several sets of metal wires;
[0011] An attitude monitoring component disposed inside the body, and a first protective component that cooperates with the attitude monitoring component;
[0012] The control module is electrically connected to the camera assembly, the drive assembly, and the attitude monitoring assembly.
[0013] When the control module and the attitude monitoring component determine that the body attitude is abnormal, the control module controls the drive component to activate the rigid component. The metal wire surrounds the front of the camera component to form a protective layer, which blocks impacts toward the camera component.
[0014] As a further improvement, a second protective component is also included. The second protective component includes a protective sheet covering the outer surface of the body facing the camera component and an inflation component disposed inside the body. The edge of the protective sheet is sealed and fixed to the body to form a sealed chamber, and the gas input end of the inflation component is in communication with the sealed chamber.
[0015] As a further improvement, the second protective component also includes a vent valve port, which is connected to the sealed chamber. The vent valve port is an electronic vent valve, which is electrically connected to a control module. The control module adjusts the opening / closing state of the electronic vent valve.
[0016] As a further improvement, the rigid component includes several sets of metal wires;
[0017] The drive assembly includes a set of reversible motors disposed on both sides of the camera assembly, the reversible motors being electrically connected to the control module, and the two reversible motors being respectively connected to the two ends;
[0018] Under normal conditions, the control module controls the reversible motor to rotate forward, loosens the metal wire, and controls the middle of the metal wire to be biased towards the camera component.
[0019] In operation, the control module controls the reversible motor to reverse, taut the metal wire, and controls the middle part of the metal wire to be in front of the camera component.
[0020] As a further improvement, the attitude monitoring component includes a gyroscope rotatably mounted in the middle of the body, an accelerometer, a fluid velocity sensor, an IMU, and a depth sensor mounted below the gyroscope. The control module is electrically connected to the gyroscope, accelerometer, fluid velocity sensor, IMU, and depth sensor. The control module includes an anomaly detection unit, which receives and analyzes data from the gyroscope, accelerometer, fluid velocity sensor, IMU, and depth sensor to determine whether the body's attitude is normal or abnormal.
[0021] As a further improvement, the inflation assembly includes a mounting slot at the bottom of the body, a gas cylinder inserted into the mounting slot, and a sealing plate to close the mounting slot. A gas input valve connected to the sealed chamber is provided in the mounting slot. The gas input valve is electrically connected to the control module. The outlet of the gas cylinder is inserted into the gas input valve, and the mounting slot is closed by bolts through the sealing plate.
[0022] As a further improvement, the gas input valve is an electronic check valve. When the gas cylinder's input port is inserted into the gas input port, the release of gas from the gas cylinder is controlled by the gas input valve.
[0023] As a further improvement, the body is recessed inward on the side facing the forward end, and the camera component is embedded inside the recess.
[0024] Beneficial effects:
[0025] When the attitude monitoring component detects an abnormal attitude or potential impact risk, the control module responds quickly. First, the drive component triggers the rigid component to form a physical protective layer, which surrounds and protects the camera component, thus forming a protective structure.
[0026] Simultaneously, the control module activates the inflation component, injecting gas into the sealed chamber to increase the internal gas density, thereby expanding the outer protective sheet and forming the first protective layer. This layer uses high-pressure gas to buffer external impacts. The high-pressure gas generated within the sealed chamber also creates strong buoyancy in the water, allowing the machine to rise rapidly and escape from areas with strong currents or impact risks.

Thus, a feature defined as "second" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0040] Reference Figure 1-9 As shown, an impact-resistant underwater detection device includes:
[0041] The body 1, and the camera assembly 2 disposed on the side of the front end of the body 1;
[0042] A first protective component 6 is provided on the side of the body 1 facing the camera component 2. The first protective component 6 includes a rigid component 61 disposed on the side of the camera component 2 and a driving component 62 that drives the rigid component 61 to switch between open and closed states.
[0043] An attitude monitoring component 3 is installed inside the body 1, and a first protective component 6 cooperates with the attitude monitoring component 3;
[0044] Control module 5, which is electrically connected to camera component 2, drive component 62, and attitude monitoring component 3;
[0045] When the control module 5 and the attitude monitoring component 3 determine that the body 1 has an abnormal attitude, the control module 5 and the drive component 62 work together to switch the rigid component 61 to the open state, forming a protective layer around the camera component 2, and blocking impacts toward the camera component 2 through the protective layer.
[0046] This underwater detection device designed for rocky sea areas is primarily used to protect underwater detection equipment in complex sea environments. In some complex sea areas, reefs and undercurrents exist. Undercurrents are strong and unpredictable currents that can impact underwater detection equipment with considerable force. If the equipment lacks sufficient stability, it can easily be carried by the undercurrents and struck against the reefs, causing damage or malfunction. This is particularly dangerous in complex rocky terrain, as undercurrents may push the equipment into the rocks, causing impact to the lens and potentially preventing it from escaping. This device protects the underwater detection equipment during operation. Its specific operating conditions are as follows:
[0047] During normal operation, the camera component 2 of the device is turned on to monitor the underwater environment and collect data.
[0048] The attitude monitoring component 3 monitors the attitude of the body 1 in real time and transmits the data to the control module 5.
[0049] When the attitude monitoring component 3 detects an attitude abnormality in the body 1, or encounters an undercurrent or impact risk, and determines the attitude abnormality based on its feedback data, the control module 5 will respond immediately, specifically as follows:
[0050] By cooperating with the control module 5 and the drive component 62, the rigid component 61 is triggered to switch to the open state, quickly forming a second protective layer surrounding the camera component 2 to physically block potential impacts.
[0051] Simultaneously, control module 5 activates inflation assembly 42, injecting gas into sealed chamber 43 to increase internal gas density, thereby expanding outer protective sheet 41 and forming the first protective layer for inflation protection. This layer uses high-pressure gas to buffer external impacts. The high-pressure gas formed within sealed chamber 43 also creates strong buoyancy in the water, allowing the body 1 to rise rapidly and escape from areas with undercurrents or impact risks.
[0052] Compared to existing solutions, this approach enhances impact resistance by incorporating multiple layers of protective components. These include a gas-cushioned buffer layer (inflatable protective sheet 41) and additional rigid protection (first rigid component 61) to address potential collisions or impacts. An attitude monitoring component 3 continuously monitors the equipment's status; upon detecting any anomalies, the control module 5 quickly coordinates various protective mechanisms to safeguard the equipment.
[0053] The control module 5 integrates the control of multiple functional units, achieving a high degree of automation and eliminating the need for manual intervention, thereby improving the device's autonomy and real-time responsiveness. This device can have a built-in power supply or be connected to an external power cord. In this embodiment, a built-in power supply is used, electrically connected to the control module. The control module is equipped with a wireless transceiver module for interaction with an external control terminal.
[0054] When the device triggers the aforementioned abnormal attitude protection mode, after the device is out of danger and before resuming its mission, the gas pressure inside the sealed chamber 43 needs to be released. Therefore, the second protection component 4 also includes a vent valve 44, which is connected to the sealed chamber 43. The vent valve 44 is an electronic vent valve, electrically connected to the control module 5, which adjusts the opening / closing state of the electronic vent valve.
[0055] The body 1 has a recessed hole on the side facing forward, and the camera component 2 is embedded inside the recessed hole.
[0056] In complex sea areas, especially those with dense reefs, underwater detection equipment may encounter strong currents and impacts from floating objects. While the first-layer rigid component 61 and the inflatable shield can withstand impacts under normal conditions, there may still be a risk of insufficient protection under more extreme conditions.
[0057] In complex sea areas, especially those with dense reefs, underwater detection equipment may encounter strong currents and impacts from floating objects. While the first-layer rigid component 61 and the inflatable shield can withstand impacts under normal conditions, there may still be a risk of insufficient protection under more extreme conditions.
[0058] The rigid component 61 is designed to address the issue of the camera assembly 2 being subjected to impacts from different directions and intensities in complex underwater environments. While the first protective layer and the inflatable protective layer provide a certain level of protection, they may not offer sufficient impact resistance against stronger or more direct impacts. This necessitates further protective measures, namely the rigid component 61.
[0059] To enhance the impact resistance of the front of the camera assembly 2 and ensure effective protection of core equipment components in extreme environments, the following specific configuration is made: the rigid assembly 61 includes several sets of metal wires 611;
[0060] The drive assembly 62 includes a set of reversible motors 612 disposed on both sides of the camera assembly 2. The reversible motors 612 are electrically connected to the control module 5, and the two reversible motors 612 are respectively connected to the two ends of the metal wire 611.
[0061] In normal operation, the control module 5 controls the reversible motor 612 to rotate forward, loosens the metal wire 611, and controls the middle of the metal wire 611 to be biased towards the camera component 2.
[0062] In operation, the control module 5 controls the reversible motor 612 to reverse, tighten the metal wire 611, and control the middle part of the metal wire 611 to be in front of the camera component 2.
[0063] The metal wire 611 is controlled by several sets of reversible motors 612. This part of the protection system is operated by two reversible motors 612 under the control of the control module 5.
[0064] Under normal conditions, the reversible motor 612 rotates forward, and the metal wire 611 is in a relaxed state to ensure that it does not interfere with the normal working field of view of the camera component 2.
[0065] Once a threat of water flow or physical impact is detected, the control module 5 reverses the motor, tauting the metal wire 611 and positioning it in front of the camera assembly 2.
[0066] The taut metal wire 611 forms a tight protective net, enhancing the elastic protection of the front of the camera component 2 and effectively resisting direct and high-intensity impacts.
[0067] By providing an additional layer of physical protection, especially resistance to potential direct impacts to the front of camera component 2.
[0068] The device maintains its flexibility by adjusting the shape of the metal wire 611, without affecting the normal working field of vision, and only provides protection when needed.
[0069] Overall, the rigid component 61 complements the other protective layers, forming a multi-layered protection system. This ensures that the underwater detection device maintains the integrity of its core components and the continuity of data acquisition, even under the harshest environmental conditions.
[0070] Among them, the metal wire 611 is made of shape memory metal material. In its relaxed state, it bends toward the adjacent side to avoid the area where the camera component 2 is located, thus making way.
[0071] The diameter of the metal wire 611 is between 1 and 1.5 mm. In this embodiment, the diameter of the metal wire 611 is not less than 1 mm, and 10 wires are arranged with an intermittent spacing of 5-10 mm.
[0072] The prerequisite for the coordinated activation of the aforementioned multiple protective components is the detection of attitude anomalies through the attitude monitoring component 3. Therefore, refer to... Figure 6As shown, the attitude monitoring component 3 includes a gyroscope 31 rotatably mounted in the middle of the body 1, an accelerometer 32, a fluid velocity sensor 33, an IMU 34, and a depth sensor 36 mounted below the gyroscope 31. The control module 5 is electrically connected to the gyroscope 31, the accelerometer 32, the fluid velocity sensor 33, the IMU 34, and the depth sensor 36. The control module 5 includes an anomaly judgment unit, which receives and analyzes data from the gyroscope 31, the accelerometer 32, the fluid velocity sensor 33, the IMU 34, and the depth sensor 36 to determine whether the attitude of the body 1 is normal or abnormal.
[0073] Since a through hole 11 is provided in the middle of the body 1, the gyroscope 31 is installed in the through hole 11 through a fixed bracket 35. An acceleration sensor 32, a fluid velocity sensor 33, an IMU 34, and a depth sensor 36 can be embedded on the side of the bracket 35 close to the body 1.
[0074] It also includes an attitude adjustment module 7 disposed below the gyroscope 31, the attitude adjustment module 7 including a first turbine 71 and a first drive motor 73 that drives the first turbine 71;
[0075] A set of second turbines 74 are arranged on both sides of the body 1, and a second drive motor 75 drives the second turbines 74. The outer side of the second turbines 74 is also covered with baffles 72, and the baffles 72 are fixedly connected to the body 1.
[0076] To ensure that the underwater detection device can effectively protect itself and operate stably in complex environments, firstly, real-time attitude monitoring is implemented. This involves continuously acquiring real-time status data of the device, including rotation information detected by the gyroscope 31, motion changes sensed by the accelerometer 32, surrounding water flow velocity measured by the fluid velocity sensor 33, comprehensive position information provided by the IMU 34, and depth data fed back by the depth sensor 36. This data is then transmitted via electrical connection to the anomaly judgment unit within the control module 5 for comprehensive judgment.
[0077] In underwater detection equipment, these sensors, through complementary and collaborative methods, provide the necessary data support for attitude monitoring and control.
[0078] The gyroscope 31 is mainly used to detect the rotation angle and angular velocity of the device, enabling it to sense changes in the device's attitude in three-dimensional space. It provides data on the device's rotation direction and speed for overall attitude determination, helping the anomaly detection unit identify whether there is an unknown rotational tendency.
[0079] Accelerometer 32 detects the linear acceleration of the device, providing real-time dynamic response to changes in motion. Combined with data from gyroscope 31, the device's attitude in the forward direction is corrected, and the acceleration changes are analyzed to determine if they conform to the desired motion.
[0080] The fluid velocity sensor 33 measures the flow velocity of the water surrounding the equipment, providing basic data for hydrodynamic analysis. It also helps determine the impact of the external environment on the equipment's movement, such as whether sudden changes in water flow cause abnormal posture, and assists other sensors in correcting the posture.
[0081] The IMU34 (Inertial Measurement Unit) integrates a gyroscope 31 and an accelerometer, providing comprehensive position information and attitude estimation. As the primary attitude measurement tool, it provides comprehensive data to help the anomaly detection unit make fast and accurate attitude judgments and adjustment strategies.
[0082] The depth sensor 36 detects the current underwater depth of the device, helping to establish the working surface range. Combined with data from other sensors, it can determine whether attitude instability is caused by changes in depth and provide early warnings for timely adjustments.
[0083] From startup, the devices utilize a collaborative system of sensors to collect and provide real-time feedback of various attitude-related parameters. Data from all sensors is aggregated into the anomaly detection unit of control module 5 for data fusion and calculation. Cross-validation of multi-source data determines whether the device is in a stable state.
[0084] When data from one or more sensors exceeds a set threshold range, the anomaly detection unit confirms the specific attitude anomaly by integrating information from all sensors.
[0085] For example:
[0086] To detect attitude anomalies, we can fuse data from various sensors into a unified algorithm. Typically, techniques such as Kalman filtering or extended Kalman filtering (EKF) are used for data fusion to obtain accurate attitude estimation.
[0087] Here's a simplified example to illustrate how to determine attitude anomalies using sensor data and formulas:
[0088] 1. Attitude estimation
[0089] Attitude estimation requires calculating the pitch, roll, and yaw angles of the three axes. These angles can be calculated using gyroscopes, accelerometers, and magnetometers (if applicable).
[0090] Gyroscope 31: Provides angular velocity, which is integrated to obtain the attitude angle.
[0091] Accelerometer: Used to provide tilt angle information and calculate pitch and roll.
[0092] Magnetometer (usually integrated into IMU34): used for calibration and to provide yaw angle reference (not mentioned in the original description, but usually part of attitude estimation).
[0093] 2. Preliminary attitude calculation based on accelerometers
[0094] Taking a simple preliminary calculation of pitch and roll angles as an example:
[0095] Here, (a_x, a_y, a_z) are the accelerometer readings on the x, y, and z axes, respectively.
[0096] The attitude is dynamically adjusted using the angular velocity data from gyroscope 31.
[0097] Where ωx, ωy, and ωz are the angular velocity readings of gyroscope 31, and ωz is the time interval.
[0098] 4. Set threshold
[0099] The updated pose data is compared with a preset normal threshold; if the threshold is exceeded, it is considered abnormal.
[0100] Define the normal operating range, specifying threshold ranges for Roll, Pitch, and Yaw, for example:
[0101] At this point, an exception is recorded, and the subsequent adjustment mechanism is triggered.
[0102] 5. Data fusion and comprehensive anomaly detection
[0103] By using an internal Kalman filter, the advantages of data from the gyroscope 31 and accelerometer can be combined to filter out noise and obtain a stable and reliable attitude. Since filters are typically included, they will not be discussed further.
[0104] By employing state estimation methods, and using multiple sensors to estimate and correct the same parameters, a consistent anomaly judgment standard is formed.
[0105] Implementing such calculations and anomaly detection can more effectively respond to detected deviations and adjust the equipment posture in a timely manner, ensuring the stability and reliability of the device in different water flow environments.
[0106] To assist in the control of ascent and descent, the control module 5 controls the first turbine 71 and the second turbine 74 to be driven by their respective drive motors, so that the device can adjust its direction and attitude.
[0107] The first turbine 71 and the second turbine 74 adjust the water flow path. By converting the rotational force of the first turbine 71 and the second turbine 74, the attitude of the machine body 1 is adjusted back to the normal state as much as possible. The fixed baffle 72 protects the second turbine 74 from impact damage. At the same time, it works with the second turbine 74 to change the direction of water flow and provide stable hydrodynamic assistance for attitude correction.
[0108] The components work efficiently together through the control module 5 and the anomaly detection unit to achieve a closed-loop response from anomaly detection to implementing protection and attitude adjustment. This ensures both the safety of the equipment and the continuity of the detection mission and the integrity of data acquisition. While inheriting the protection functions, the attitude adjustment module 7 ensures that the equipment is always in optimal working condition.
[0109] In the above scheme, the first protective layer is mainly constructed by the inflation component 42 and the protective sheet 41. However, the gas filling design is not described in detail. Therefore, the gas filling structure is further designed as follows: The inflation component 42 includes an installation groove 421 set at the bottom of the body 1, a gas cylinder 422 inserted into the installation groove 421, and a sealing plate 423 that closes the installation groove 421. A gas input valve 424 connected to the sealed chamber 43 is provided in the installation groove 421. The gas input valve 424 is electrically connected to the control module 5. The output port of the gas cylinder 422 is inserted into the gas input valve 424. The installation groove 421 is closed by bolts through the sealing plate 423.
[0110] The gas input valve 424 is an electronic one-way valve. When the input port of the gas cylinder 422 is inserted into the gas input port, the release of gas from the gas cylinder 422 is controlled by the gas input valve 424.
[0111] During the equipment preparation phase, install the gas cylinder 422 in the mounting slot 421 at the bottom of the machine body 1. Ensure that the outlet of the gas cylinder 422 is correctly inserted into the gas input valve 424. At the same time, use the sealing plate 423 to seal the mounting slot 421 and tighten it with bolts to ensure that the gas cylinder 422 is fixed and remains airtight.
[0112] When the first protective layer needs to be activated (e.g., when the device is detected to be buoyant quickly or when buoyancy needs to be increased to cope with environmental changes), the control module 5 triggers the electronic check valve.
[0113] An electronic one-way valve controls the gas to flow unidirectionally from the gas cylinder 422 into the sealed chamber 43, thereby expanding the protective sheet 41 to form the first protective layer.
[0114] Because the gas inlet valve 424 is an electronic check valve, it effectively prevents accidental reverse flow, ensuring the safety of the equipment under any circumstances. After equipment operation is completed or when inspection is required, gas supply can be stopped by closing the gas inlet valve 424, ensuring safety during maintenance.
[0115] By combining the electronic check valve with the control module 5, comprehensive control over gas filling is achieved, which not only improves the response speed but also allows for precise control of the gas filling amount according to real-time requirements.
[0116] Select the appropriate gas type (such as helium, nitrogen, or compressed air) based on the different environments in which the equipment will be used, whether in space or underwater. Choosing the right gas ensures its effectiveness and safety in the target environment.
[0117] It is worth noting that intelligent algorithms are embedded in control module 5 to dynamically adjust the gas filling strategy based on multi-sensor data. For example, feedback control algorithms such as PID control are used to improve the response sensitivity of the protective layer.
[0118] Consider adding redundant design elements, such as a spare gas cylinder 422 or a dual valve system, to ensure the stability and functionality of the equipment in multiple layers, in case of emergencies.
[0119] The thickness of the protective sheet 41 is 0.5-1mm.
[0120] The protective sheet 41 is made of a material with expansion and ductility properties and impact resistance. Suitable materials include: polyurethane (TPU): excellent elasticity and flexibility, capable of withstanding multiple expansions and contractions. Its superior abrasion resistance and tear resistance help resist punctures from sharp objects.
[0121] Kevlar (bulletproof fiber) coated elastic material: Although Kevlar itself lacks elasticity, combining it with elastomer materials can improve puncture and cut resistance. This combination is suitable for applications requiring additional protection in extreme environments.
[0122] Nylon-reinforced polymers: possess excellent abrasion resistance, making them suitable for use in harsh environments. After special coating treatment, their puncture and impact resistance can be further improved.
[0123] Silicone rubber composite material: Excellent elasticity, able to maintain its shape without damage when inflated. Excellent resistance to high temperatures and environmental corrosion.
[0124] In this embodiment, the protective sheet 41 is a composite of polyurethane and Kevlar materials.
[0125] Within a certain thickness range, the material must simultaneously ensure both flexibility and strength. In this embodiment, the protective layer is designed to be 0.5-1mm thick, which is sufficient to support expansion without easily tearing, and also provides some puncture resistance. Materials of this thickness are relatively lightweight and suitable for use without significantly increasing the overall weight of the equipment, especially for devices requiring buoyancy or portability.
[0126] It needs to expand effectively without damage when filled with gas, thus forming a dense protective layer. Specifically, the thickness is 1mm when unfilled and 0.5mm after filling.
[0127] By selecting these materials and designing their thickness, not only are excellent expansion and protection functions achieved, but the durability and practicality of the equipment are also guaranteed. This provides reliable protection for the stable operation of the equipment in dynamically changing environments.
[0128] After the protective sheet 41 is inflated, a mechanism is needed to provide additional internal support to further enhance its impact resistance, ensuring that the protective sheet 41 maintains its shape and structural integrity when facing external pressure or impact. Additionally, when the equipment is in a deep seabed environment with high external pressure, gas may not be able to smoothly fill the sealed chamber 43 in a short time. A method is needed to quickly push the protective sheet 41 into a shape that meets the usage requirements, facilitating rapid gas filling.
[0129] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood.
