Description
Technical Field
[0001] The utility model relates to the technical field of underwater reef detection, in particular to an underwater reef clearing detection device. Background Art
[0002] With the development of the marine economy, the smooth flow of underwater waterways is crucial for ensuring shipping safety. However, in actual operations, various rock obstacles often exist within waterways due to natural or human factors, seriously affecting the safety and efficiency of ship navigation. Currently, underwater reef clearance is typically carried out by manually inspecting and removing underwater obstacles such as reefs or using sonar detection. While these two methods can accomplish their tasks to a certain extent, they still present numerous limitations and challenges in complex environments.
[0003] At present, manual inspection by divers mainly involves professionals carrying necessary tools and equipment to dive into the water for visual inspection and manual processing. Although this method is highly flexible, it is limited by human physiological limits, has low work efficiency and is difficult to ensure safety. In addition, sonar detection relies on advanced acoustic instruments to transmit ultrasonic signals to the target area and receive the reflected information to judge the size and shape of the object, and then determine whether further action is needed. Although this method can achieve long-distance and rapid scanning of the distribution of potential threat points within the entire water area, sonar detection equipment is usually installed on ships, and may experience signal attenuation due to the long distance from underwater obstacles, which can easily lead to missed detection. In this regard, the present application proposes an underwater reef clearing detection device. Utility Model Content
[0004] This utility model addresses the shortcomings of traditional manual diving inspections, which are time-consuming, labor-intensive, and risky, and cannot adapt to the operational requirements of deep sea or dangerous waters. Sonar detection is subject to factors such as signal attenuation, and its accuracy under specific conditions still needs to be improved. Therefore, an underwater reef clearing detection device is provided. The specific technical solution is as follows:
[0005] An underwater reef clearing and detection device comprises a counterweight cylinder, a sonar probe installed at the bottom of the counterweight cylinder and used for underwater reef clearing and detection, and a connecting rope installed in the counterweight cylinder and used to place the sonar probe underwater. A protective mechanism is provided on the outside of the counterweight cylinder, and a plurality of counterweight blocks for weighting the sonar probe are movably provided in the counterweight cylinder. The protective mechanism comprises a plurality of fixed sleeve rods fixed on the outer wall of the counterweight cylinder, a movable rod slidably arranged in the fixed sleeve rod, and a roller rotatably arranged at one end of the movable rod for rotating and unloading force in the event of a collision. A first spring for buffering in the event of a collision is fixed between the inner wall of the fixed sleeve rod and one end of the movable rod, and a buffering and filtering mechanism is provided at the bottom of the fixed sleeve rod.
[0006] By adopting the above technical solution, the sonar probe can be placed underwater through the connecting rope. Combined with the weighting of the counterweight block in the counterweight tube, the sinking of the sonar probe can be accelerated to shorten the distance between the sonar probe and underwater obstacles such as reefs, thereby enhancing the signal and improving the accuracy of underwater reef clearance detection.
[0007] Optionally, a reflective cover is fixedly provided at the bottom center of the counterweight cylinder, the sonar probe is fixedly installed in the reflective cover, a counterweight slot is provided in the counterweight cylinder, the connecting rope is fixedly connected to the bottom center of the counterweight slot of the counterweight cylinder, and the counterweight block is located at the inner bottom of the counterweight slot.
[0008] By adopting the above technical solution, the reflective cover can reflect the sonar emitted by the sonar probe, making the sonar signal more concentrated, thereby strengthening the sonar signal. The sonar probe can use sonar to detect underwater obstacles such as reefs.
[0009] Optionally, one end of the movable rod is rotatably connected to a rotating rod, and the roller is fixedly connected to the outer wall of the bottom end of the rotating rod. The buffer filtering mechanism includes a conical tube fixed at the bottom of one end of the fixed sleeve rod away from the roller and with a diameter gradually increasing from top to bottom, and a filter screen fixed at the bottom of the inner wall of the conical tube.
[0010] By adopting the above technical solution, when the device collides with an underwater object, the roller can first unload the force by rotating, and cushion the device by compressing the first spring through the movable rod. At the same time, the water in the fixed sleeve rod will also be compressed and splashed out through the tapered tube to further cushion the device, so that the device is not easily damaged after colliding with the underwater object.
[0011] Optionally, two mesh plates are slidably provided on both sides of the top of the counterweight cylinder, the connecting rope is fitted and abutted between the two mesh plates, and a connecting plate located outside the counterweight cylinder is fixedly provided at one end of the mesh plate away from the connecting rope, and a second spring for pulling the connecting plate toward the counterweight cylinder is fixedly provided between the outer walls of the two connecting plates and both sides of the counterweight cylinder, and an annular brush for clearing and cleaning the moving mesh plate is fixedly provided on the top of the inner wall of the counterweight cylinder.
[0012] By adopting the above technical solution, the tension of the second spring can drive the two mesh plates to move and cover the top opening of the counterweight cylinder, thereby preventing the counterweight block in the counterweight cylinder from falling out of the opening after a collision.
[0013] In summary, the present invention has at least one of the following beneficial effects:
[0014] 1. The sonar probe can be lowered underwater through the connecting rope. The weight of the counterweight block in the counterweight tube can accelerate the sinking of the sonar probe, shortening the distance between the sonar probe and underwater obstacles such as reefs, thereby enhancing the signal and improving the accuracy of underwater reef clearance detection. It also significantly improves the speed and accuracy of underwater rock obstacle clearance operations, greatly shortens the project cycle, reduces operating costs, avoids the uncertainties brought about by manual underwater inspections, and enhances the safety factor of operations.
[0015] 2. Through the setting of the protective mechanism, the sonar probe and other components can be protected, so that when the device collides with an underwater object, the roller can first unload the force by rotating, and the first spring is compressed by the movable rod to cushion the device. At the same time, the water in the fixed sleeve will also be compressed and splashed out through the tapered tube to further cushion the device, so that the device is not easily damaged after colliding with an underwater object.
[0016] 3. Through the tension of the second spring, the two mesh plates can be driven to move and cover the opening on the top of the counterweight cylinder to prevent the counterweight block in the counterweight cylinder from falling out of the opening after a collision. The mesh plates can connect the inside and outside of the counterweight cylinder, allowing water to enter the inside of the counterweight cylinder to further increase the weight of the counterweight cylinder, and the annular brush can dredge and clean the moving mesh plates, which is convenient and practical.

DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-4 The utility model is described in further detail.
[0023] The utility model discloses an underwater reef clearing detection device, referring to Figure 1-2, including a counterweight cylinder 1, a sonar probe 2 and a connecting rope 3. A counterweight groove 11 is opened in the counterweight cylinder 1, and the counterweight cylinder 1 is in the shape of a hollow cylinder.
[0024] Reference Figure 1-2 The sonar probe 2 is installed at the bottom of the counterweight cylinder 1. A reflective cover 21 is fixed at the center of the bottom of the counterweight cylinder 1. The sonar probe 2 is fixedly installed in the reflective cover 21. The reflective cover 21 can connect the sonar probe 2 and the counterweight cylinder 1. The reflective cover 21 can reflect the sonar emitted by the sonar probe 2, making the sonar signal more concentrated, thereby strengthening the sonar signal. The sonar probe 2 can detect underwater obstacles such as reefs through sonar, and the detection principle is a public technology, which will not be elaborated here.
[0025] Reference Figure 1-2 The connecting rope 3 is installed in the counterweight cylinder 1, and the connecting rope 3 is fixedly connected to the bottom center of the counterweight slot 11 of the counterweight cylinder 1. The top of the connecting rope 3 can be connected to an external ship, and the signal line of the sonar probe 2 is wrapped inside the connecting rope 3. The signal line inside the connecting rope 3 is connected to the main host of the sonar detection equipment on the ship. The sonar detection equipment is a public technology and will not be described in detail here. Through the movement of the hull, the device can achieve all-round, all-weather uninterrupted monitoring and management based on DTM and other technologies through the sonar probe 2, which helps to timely discover and deal with sudden dangerous situations and maintain a stable and controllable water traffic safety situation.
[0026] Reference Figure 1 、 Figure 2 and Figure 4 A number of counterweight blocks 12 for weighting the sonar probe 2 are movably provided in the counterweight cylinder 1. The counterweight blocks 12 are located at the inner bottom of the counterweight groove 11. The counterweight blocks 12 can weight the counterweight cylinder 1 and the sonar probe 2 to accelerate the sinking of the sonar probe 2. After sinking, the sonar probe 2 can shorten the distance to underwater obstacles such as reefs, thereby enhancing the signal and improving the accuracy of underwater reef clearance detection.
[0027] Reference Figure 1-2 Two mesh plates 5 are slidingly provided on both sides of the top of the counterweight cylinder 1, and the connecting rope 3 is cooperated to abut between the two mesh plates 5. A connecting plate 51 located outside the counterweight cylinder 1 is fixed at one end of the mesh plate 5 away from the connecting rope 3. A second spring 52 is fixed between the outer walls of the two connecting plates 51 and both sides of the counterweight cylinder 1 to pull the connecting plate 51 toward the counterweight cylinder 1. The counterweight cylinder 1 can support and limit the two mesh plates 5. After the two mesh plates 5 abut against the connecting rope 3, they can cover the top opening of the counterweight cylinder 1 to prevent the counterweight block 12 in the counterweight cylinder 1 from falling out of the opening of the counterweight cylinder 1 after a collision.
[0028] The connecting plate 51 can connect the second spring 52 and the mesh plate 5, and under the pulling force of the second spring 52, the two mesh plates 5 will be pulled toward the inside of the counterweight cylinder 1, thereby fixing the two closed mesh plates 5. The mesh plate 5 can connect the inside and outside of the counterweight cylinder 1, so that water can enter the inside of the counterweight cylinder 1 to further increase the weight of the counterweight cylinder 1.
[0029] Reference Figure 1-2 An annular brush 53 for dredging and cleaning the movable mesh plate 5 is fixedly provided on the top of the inner wall of the counterweight cylinder 1. The bristles at the bottom of the annular brush 53 are inserted into the mesh holes of the mesh plate 5. When the staff pulls the two mesh plates 5 to the outside of the counterweight cylinder 1 to remove the counterweight block 12, the bristles at the bottom of the annular brush 53 can dredge the movable mesh plate 5 and brush away foreign matter attached to the mesh plate 5 over a large area, thereby cleaning the mesh plate 5.
[0030] Reference Figure 1-3 A protective mechanism is provided on the outside of the counterweight cylinder 1, and the protective mechanism includes several fixed sleeve rods 4 fixedly arranged on the outer wall of the counterweight cylinder 1, a movable rod 41 slidingly arranged in the fixed sleeve rod 4, and a roller 42 rotatably arranged at one end of the movable rod 41 for rotating and unloading force in case of collision. One end of the movable rod 41 is rotatably connected to a rotating rod 43, and the roller 42 is fixedly connected to the outer wall of the bottom end of the rotating rod 43. A first spring 44 for buffering in case of collision is fixedly provided between the inner wall of the fixed sleeve rod 4 and one end of the movable rod 41. The rotating rod 43 can connect the movable rod 41 with the roller 42, and the first spring 44 can connect the fixed sleeve rod 4 with the movable rod 41.
[0031] When the device collides with underwater animals or obstacles, the roller 42 will rotate to unload the force. At this time, the movable rod 41 will slide into the fixed sleeve rod 4 due to the collision, thereby compressing the first spring 44 to cushion the device.
[0032] Reference Figure 1-3 A buffering and filtering mechanism is provided at the bottom of the fixed sleeve rod 4, which includes a tapered tube 45 fixed at the bottom of one end of the fixed sleeve rod 4 away from the roller 42 and with a diameter gradually increasing from top to bottom, and a filter screen 46 fixed at the bottom of the inner wall of the tapered tube 45. When the movable rod 41 slides into the fixed sleeve rod 4 after the collision, the water in the fixed sleeve rod 4 will also be compressed and splashed out through the fine holes at the bottom of the tapered tube 45 to further buffer the device. In conjunction with the unloading force of the roller 42 and the spring of the first spring 44, the device is not easily damaged after colliding with an underwater object. The filter screen 46 can filter the water entering the tapered tube 45 and block foreign matter such as aquatic plants in the water.
[0033] The implementation principle of an underwater reef clearing detection device according to an embodiment of the utility model is as follows:
[0034] When in use, the top end of the connecting rope 3 can be connected to an external ship, and then the two mesh plates 5 are pulled toward the outside of the counterweight cylinder 1, the counterweight block 12 is placed into the counterweight slot 11 of the counterweight cylinder 1, and then the two mesh plates 5 are loosened. At this time, the two mesh plates 5 will press against the connecting rope 3 under the tension of the second spring 52 to cover the top opening of the counterweight cylinder 1;
[0035] Then the device is slowly lowered into the water. The counterweight block 12 can add weight to the counterweight tube 1 and the sonar probe 2 to speed up the sinking of the sonar probe 2. After sinking, the sonar probe 2 can shorten the distance to underwater obstacles such as reefs, thereby enhancing the signal and improving the accuracy of underwater reef clearance detection.
[0036] When the device collides with underwater animals, obstacles or other objects, the roller 42 will unload the force by rotating. At this time, the movable rod 41 will slide into the fixed sleeve rod 4 due to the collision, thereby compressing the first spring 44 to cushion the device. At the same time, the water in the fixed sleeve rod 4 will also be compressed and splashed out through the fine holes at the bottom of the tapered tube 45 to further cushion the device, so that the device is not easily damaged after colliding with underwater objects.
