Description

Technical Field

[0001] This invention belongs to the field of aquatic organism surveying technology, specifically a surveying device and method for aquatic organism observation stations. Background Technology

[0002] In the surveying of aquatic biological resources and the monitoring of aquatic ecosystems, existing aquatic observation stations generally adopt a survey mode that combines sonar and underwater cameras. Sonar is used to complete large-scale underwater scanning, precise target positioning and contour recognition, while high-definition cameras are used to intuitively capture the real morphology, species characteristics and activity details of aquatic organisms. By complementing and fusioning sonar detection data and video image data and conducting collaborative analysis, the shortcomings of single detection methods can be effectively made up for. This can fully meet the practical application needs of refined observation of aquatic organisms, long-term behavior tracking and recording, and source analysis of aquatic ecological environment.

[0003] Currently, in aquatic life survey operations, survey cameras need to be placed underwater for extended periods. Natural water bodies generally suffer from turbidity and high levels of suspended matter. At the same time, various microorganisms and plankton in the water easily adhere to the surface of the camera's optical lenses. As the equipment remains underwater for extended periods, microorganisms continuously proliferate and accumulate, gradually forming an obstruction layer on the lenses. This not only obstructs the field of view and reduces light transmittance but also causes image blurring, color distortion, and decreased clarity, severely interfering with underwater scene acquisition and significantly impacting the imaging quality and accuracy of aquatic life observation data. Therefore, this invention provides a survey device and method for aquatic life observation stations. Summary of the Invention

[0011] The sidewall of the unclogging ball is connected to a set of rotating shafts by a torsion spring, and an extension plate is fixedly connected to the surface of the rotating shafts. The extension plate is set at an angle.

[0012] The top surface of the base is rotatably connected to a first gear. A second motor that drives the first gear to rotate is installed on the base. The second motor is connected to the base via a bracket. The base is rotatably connected to the far end of the electric telescopic rod.

[0013] A surveying method for an aquatic life observation station, the method employing the aforementioned surveying device for an aquatic life observation station, the method comprising the following steps: S1: Install the sonar onto the connecting plate, then check whether the sonar, searchlight, and camera can operate normally, and debug each device and mechanism to confirm that the multi-section electric telescopic mechanism extends and retracts smoothly, and that the buoyancy box is well sealed and has no water leakage. S2: The floating box is slowly lifted to the pre-set survey area using hoisting equipment and placed smoothly into the water to ensure that the floating box floats stably without tilting or overturning; the base position is adjusted according to the survey requirements, and the buoyancy box is anchored using anchor hooks; S3: Activate the multi-section electric telescopic mechanism, and gradually adjust the telescopic length according to the preset survey depth and range, so as to drive the base, searchlight, camera and sonar equipment to sink to the target underwater position, so that the searchlight can illuminate and ensure sufficient light in the underwater observation area; S4: Start the camera and sonar equipment.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 5 As shown in the embodiment of the present invention, a surveying device for an aquatic life observation station includes a buoyancy box 1, with a base 2 at the bottom of the buoyancy box 1; a camera 5 is fixedly connected to the top surface of the base 2, and a supplementary light 4 for supplementary lighting is also fixedly connected to the top surface of the base 2; the camera 5 is equipped with a data processing module and a data transmission module; a pair of connecting plates 3 are fixedly connected to the side wall of the base 2, and the connecting plates 3 are used to install sonar; a first motor 9 is fixedly connected to the surface of the camera 5, and a cleaning plate 10 is fixedly connected to the output end of the first motor 9; bristles 11 for cleaning the lens of the camera 5 are fixedly connected to the surface of the cleaning plate 10; the cleaning plate 10 is made of magnetic material, and a magnetic block 34 that is magnetically attracted to the cleaning plate 10 is fixedly connected to the camera 5; This application involves mounting a sonar to a connecting plate 3, then placing the exploration device at the desired observation location. The entire device floats using a buoy, with the base 2 submerged in water. A camera 5 captures underwater footage for aquatic life observation. The camera 5 processes the captured images and transmits them to a ground base station via a data transmission module. The sonar also contains a data processing module and a data transmission module. The sonar is used to observe aquatic life, and the observed data is processed by the data processing module and then transmitted to the ground via the data transmission module to complete the aquatic life survey. During prolonged use, impurities may accumulate on the lens of the camera 5. In this case, the first motor 9 can be activated to rotate the cleaning plate 10, causing the bristles 11 to clean the impurities on the lens, ensuring the clarity of the captured images and improving the survey results. After cleaning the lens, the first motor 9 stops the cleaning plate 10 at the magnetic block 34, which then attracts the cleaning plate 10, preventing it from blocking the camera 5's view.

[0022] The bottom surface of the buoyancy box 1 is fixedly connected to a multi-section electric telescopic rod 6. The bottom end of the electric telescopic rod 6 is connected to the base 2. The top end of the buoyancy box 1 is fixedly connected to a fixing rod 7, and the top end of the fixing rod 7 is fixedly connected to a hook 8. In this application, the entire device can be hoisted to a preset water level by the hook 8, and then the device is lowered to the water surface. After the base 2 is in the water, a camera 5 and a sonar will be used for surveying. At this time, the position of the base 2 in the water can be adjusted by the electric telescopic rod 6 to adjust the position of the camera 5 and the sonar, thereby increasing the survey range and obtaining more aquatic biological information.

[0023] The cleaning plate 10 has a hollow groove 12, and a set of round holes 13 are opened on the side of the hollow groove 12 near the camera 5. A pressurizing pipe 14 is connected to the hollow groove 12. After the buoyancy box 1 of this application is placed on the water surface, water will enter the hollow groove 12 through the round holes 13. When cleaning the lens, the water in the hollow groove 12 can be pressurized by the pressurizing pipe 14, so that the water in the hollow groove 12 can be sprayed onto the lens through the round holes 13 for cleaning. At the same time, the brush bristles 11 are used to clean the lens, so as to greatly improve the cleaning effect of the lens.

[0024] A connecting rod 17 is fixedly connected to the top surface of the base 2, and a pressure ring 16 is fixedly connected to the top surface of the connecting rod 17. A fixing ring is fixedly connected to the surface of the electric telescopic rod 6, and a hollow elastic ring 15 is fixedly connected to the bottom surface of the fixing ring. The end of the pressure tube 14 away from the hollow groove 12 is connected to the inside of the elastic ring 15. Since the pressure tube 14 is connected to the hollow groove 12 and the elastic ring 15, when the base 2 is in water, the elastic ring 15 will be filled with water. When the lens needs to be rinsed, the tail end of the electric telescopic rod 6 can be moved upward, so that the connecting rod 17 drives the pressure ring 16 to move upward and squeeze the elastic ring 15, thereby allowing the water in the elastic ring 15 to enter the hollow groove 12 and then spray onto the lens through the round hole 13. When the tail end of the electric telescopic rod 6 moves downward, the elastic ring 15 will recover due to its own elasticity, thereby sucking the water into the elastic ring 15. By controlling the tail end of the electric telescopic rod 6 to move up and down, the water flow can continuously impact the lens.

[0025] A guide rod 23 is provided inside the hollow groove 12, which is opposite to the circular hole 13. A cleaning ball 24 is slidably connected to the guide rod 23. A control component for controlling the movement of the cleaning ball 24 is provided inside the hollow groove 12. When rinsing the lens, water is drawn into the hollow groove 12. If the water contains impurities that may clog the circular hole 13, the cleaning ball 24 can be moved by the control component so that it slides on the guide rod 23 through the circular hole 13 to push away the impurities blocking the circular hole 13 and avoid affecting the rinsing of the lens.

[0026] The control assembly includes a partition 18 fixed inside a hollow groove 12. A vertical plate 19 is fixedly connected inside the hollow groove 12. The vertical plate 19 and the partition 18 cooperate to divide the hollow groove 12 into a first cavity 21 and a second cavity 22. A water inlet hole is provided on the partition 18. A through hole 20 corresponding to the round hole 13 is provided on the vertical plate 19. One end of the guide rod 23 is fixedly connected to the inner wall of the first cavity 21. The surface of the unclogging ball 24 is fixedly connected to... There is a pair of elastic ropes 26, and the end of the elastic rope 26 away from the drain ball 24 is fixedly connected to the vertical plate 19. In this application, after the water in the elastic ring 15 is squeezed, it will enter the first cavity 21 from the water inlet hole, and then spray out from the through hole 20. At this time, the water flow will push the drain ball 24 to move, so that the drain ball 24 passes through the round hole 13 to unclog the round hole 13. After the elastic ring 15 is stopped being squeezed, the elastic rope 26 will pull the drain ball 24 to reset.

[0027] The side wall of the drain ball 24 is connected to a set of rotating shafts 27 by a torsion spring. An extension plate 25 is fixedly connected to the surface of the rotating shafts 27, and the extension plate 25 is inclined. When the drain ball 24 passes through the round hole 13, the inner wall of the round hole 13 pushes the extension plate 25. At this time, the extension plate 25 will rotate and scrape the impurities on the round hole 13 to remove the impurities. After the drain ball 24 has completely passed through the round hole 13, the extension plate 25 will be reset by the action of the torsion spring. When the elastic rope 26 pulls the drain ball 24 to reset, the extension plate 25 will be pushed by the round hole 13 again, allowing the drain ball 24 to smoothly enter the second cavity 22.

[0028] Example 2: Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a first gear 30 is rotatably connected to the top surface of the base 2, a second motor 32 is provided on the base 2 to drive the first gear 30 to rotate, the second motor 32 is connected to the base 2 through a bracket 33, the base 2 is rotatably connected to the end of the electric telescopic rod 6, a second gear 31 is fixedly connected to the surface of the end of the electric telescopic rod 6, the second gear 31 meshes with the first gear 30, a steel cable 28 is fixedly fixed to the bottom surface of the base 2, and an anchor hook 29 is fixedly connected to the end of the steel cable 28 away from the base 2; in this application, the second motor 32 drives the first gear 30 to rotate, so that the first gear 30 moves on the second gear 31, at which time the base 2 will rotate, thereby changing the position of the camera 5 and sonar on the base 2, further improving the survey range, and the anchor hook 29 can improve the stability of the entire device in water.

[0029] like Figures 7 to 8 As shown, a surveying method for an aquatic life observation station is described. This method employs the aforementioned surveying device for an aquatic life observation station and includes the following steps: S1: Install the sonar onto the connecting plate 3, then check whether the sonar, searchlight, and camera 5 can operate normally, and debug each device and mechanism to confirm that the multi-section electric telescopic mechanism extends and retracts smoothly, and that the buoyancy box 1 is well sealed and has no water leakage. S2: The floating box is slowly lifted to the preset survey area using hoisting equipment and placed smoothly into the water to ensure that the floating box floats stably without tilting or overturning; the position of the base 2 is adjusted according to the survey requirements, and the buoyancy box 1 is anchored using anchor hook 29; S3: Activate the multi-section electric telescopic mechanism, and gradually adjust the telescopic length according to the preset survey depth and range, so as to drive the base 2, searchlight, camera 5, and sonar equipment to sink to the target underwater position, so that the searchlight can illuminate and ensure sufficient light in the underwater observation area; S4: Start camera 5 and sonar equipment. Camera 5 captures underwater images in real time, capturing the morphology and movement trajectory of aquatic organisms. The sonar equipment simultaneously detects the distribution range and density of underwater organisms and environmental parameters of the surrounding waters, and records all observation data and image data to ensure the integrity and accuracy of data collection.

[0030] The method also includes the following steps: A1: Start the first motor 9 to control the cleaning plate 10 to rotate, so that the bristles 11 can clean the impurities on the lens to ensure the clarity of the captured image; A2: By controlling the base 2 to move upward, the connecting rod 17 drives the pressure ring 16 to move upward and squeeze the elastic ring 15, so that the water in the elastic ring 15 enters the hollow groove 12 and is then sprayed onto the lens from the round hole 13. A3: The first gear 30 is driven to rotate by the second motor 32, which causes the first gear 30 to move on the second gear 31. At this time, the base 2 will rotate, thereby changing the position of the camera and sonar on the base 2 and increasing the survey range.

[0031] Working principle: By installing the sonar onto the connecting plate 3, and then placing the exploration device at the desired observation location, the entire device will float using a pontoon, with the base 2 submerged in water. Camera 5 then captures underwater images for aquatic life observation. The camera 5 processes the captured images and transmits them to the ground base station via a data transmission module. The sonar also contains a data processing module and a data transmission module. The sonar is also used to observe aquatic life; the observed data is processed by the data processing module and then transmitted to the ground via the data transmission module to complete the aquatic life survey. During prolonged use, impurities may accumulate on the lens of camera 5. At this time, the first motor 9 can be activated. 9 controls the cleaning plate 10 to rotate, so that the bristles 11 clean the impurities on the lens to ensure the clarity of the captured image and improve the survey effect. After cleaning the lens, the first motor 9 controls the cleaning plate 10 to stop at the magnetic block 34. At this time, the magnetic block 34 will attract the cleaning plate 10 to prevent the cleaning plate 10 from blocking the camera 5 from shooting. In this application, the entire device can be hoisted to the preset water level by the hook 8, and then the device is lowered to the water surface. After the base 2 is in the water, the camera 5 and sonar will be used for survey. At this time, the position of the base 2 in the water can be adjusted by the electric telescopic rod 6 to adjust the position of the camera 5 and sonar, increase the survey range, and obtain more aquatic biological information. After the buoyancy box 1 in this application is placed on the water surface, water will enter the hollow groove 12 through the round hole 13. When cleaning the lens, the water in the hollow groove 12 can be pressurized by the pressurization pipe 14, allowing the water in the hollow groove 12 to be sprayed onto the lens through the round hole 13 for cleaning. Simultaneously, the brush bristles 11 clean the lens, greatly improving the cleaning effect. Since the pressurization pipe 14 is connected to the hollow groove 12 and the elastic ring 15, when the base 2 is in the water, the elastic ring 15 will be filled with water. When the lens needs to be rinsed, the end of the electric telescopic rod 6 can be moved upward, so that the connecting rod 17 drives the pressure ring 16 to move upward and squeeze the elastic ring 15, so that the water in the elastic ring 15 enters the hollow groove 12 and is then sprayed onto the lens through the round hole 13. When the end of the electric telescopic rod 6 moves downward, the elastic ring 15 will recover due to its own elasticity, thereby sucking the water into the elastic ring 15. By controlling the end of the electric telescopic rod 6 to move up and down, the water flow can be continuously impacted on the lens. In this application, when rinsing the lens, water is drawn into the hollow groove 12. If the water contains impurities, it may clog the round hole 13. In this case, the unclogging ball 24 can be moved by the control component, so that the unclogging ball 24 slides on the guide rod 23 and passes through the round hole 13 to push away the impurities clogging the round hole 13, thus avoiding affecting the rinsing of the lens. In this application, after the water in the elastic ring 15 is squeezed, it enters the first cavity 21 from the water inlet and then sprays out from the through hole 20. At this time, the water flow will push the unclogging ball 24 to move, so that the unclogging ball 24 passes through the round hole 13 to clean the lens. When the round hole 13 is cleared, after the elastic ring 15 is stopped being squeezed, the elastic rope 26 will pull the unclogging ball 24 to reset. When the unclogging ball 24 passes through the round hole 13, the inner wall of the round hole 13 will push the expansion plate 25. At this time, the expansion plate 25 will rotate and scrape the impurities on the round hole 13 to remove the impurities. After the unclogging ball 24 has completely passed through the round hole 13, the expansion plate 25 will be reset by the action of the torsion spring. When the elastic rope 26 pulls the unclogging ball 24 to reset, the expansion plate 25 will be pushed by the round hole 13 again, allowing the unclogging ball 24 to smoothly enter the second cavity 22.

S3: Activate the multi-section electric telescopic mechanism, and gradually adjust the telescopic length according to the preset survey depth and range, so as to drive the base (2) and searchlight, camera (5) and sonar equipment to sink to the target underwater position, so that the searchlight can illuminate and ensure sufficient light in the underwater observation area; S4: Start the camera (5) and sonar equipment. The camera (5) captures underwater images in real time, capturing the morphology and activity trajectory of aquatic organisms. The sonar equipment simultaneously detects the distribution range, density and surrounding water environment parameters of underwater organisms, and records all observation data and image data simultaneously to ensure the integrity and accuracy of data collection.

10. The surveying method for an aquatic organism observation station according to claim 9, characterized in that: The method also includes the following steps: A1: Start the first motor (9) to control the cleaning plate (10) to rotate, so that the bristles (11) clean the impurities on the lens to ensure the clarity of the captured image; A2: By controlling the base (2) to move upward, the connecting rod (17) drives the pressure ring (16) to move upward and squeeze the elastic ring (15), so that the water in the elastic ring (15) enters the hollow groove (12) and is then sprayed onto the lens from the round hole (13); A3: The first gear (30) is driven to rotate by the second motor (32), so that the first gear (30) moves on the second gear (31). At this time, the base (2) will rotate, thereby changing the position of the camera and sonar on the base (2) and increasing the survey range.
