Description

Technical Field

[0001] This utility model relates to the field of underwater vehicles, and in particular to a depth-fixed anchoring device for underwater vehicles. Background Technology

[0002] Underwater vehicles are a type of underwater robot, widely used in scientific research, deep-sea operations, and exploration and rescue. Due to the special performance requirements of underwater vehicles, such as small size and high space utilization, most are equipped with anchoring devices so that they can work underwater for a long time without affecting the power source consumption due to their own weight.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the structure of most existing underwater vehicle anchoring devices is relatively simple, and the time it takes for the anchor point to touch the bottom varies depending on the depth. If the depth of the anchor point cannot be determined and controlled independently during this process, it is easy to cause deviations in the final suspension depth, and further improvements are needed. Utility Model Content

[0004] In order to improve the problem that the existing anchoring devices of most underwater vehicles have a relatively simple structure and the time to touch the bottom after the anchor point is released varies depending on the depth, and if the depth of the anchor point cannot be determined and controlled independently during this process, it is easy to cause the final suspension depth to deviate, which requires further improvement, this application provides an underwater vehicle depth-fixed anchoring device.

[0005] This application provides a depth-fixed anchoring device for an underwater vehicle, which adopts the following technical solution: The depth-fixed anchoring device for an underwater vehicle includes an underwater vehicle body and an anchoring assembly. The anchoring assembly includes an outer shell, the top of which is fixedly connected to the bottom of the underwater vehicle body. A winding reel is provided inside the outer shell, and a cable is provided on the lower side of the winding reel. A reflector is fixedly connected to the bottom of the cable, and an anchoring head is fixedly connected to the bottom of the reflector.

[0006] In a further configuration, the top end of the cable is fixedly connected to a winding reel, and the cable is wound around the winding reel.

[0007] Furthermore, the winding reel is fixedly connected to rollers at both ends, and the left end of the left roller is rotatably connected to the inner wall of the left end of the outer casing via a bearing.

[0008] Further, a servo motor is installed inside the outer casing, and the right end of the rotating roller on the right side is fixedly connected to the left output end of the servo motor.

[0009] Furthermore, a control module is provided on the right side of the inner wall at the top of the outer casing, and the control module is electrically connected to the servo motor.

[0010] Further, an infrared rangefinder is provided on the left side of the inner wall at the top of the outer casing, and the infrared rangefinder is electrically connected to the control module.

[0011] Furthermore, slots are provided on both the left and right sides of the bottom of the outer casing, and inserts are fixedly connected to both the left and right sides of the top of the reflector, with the top of each insert being inserted into the slot.

[0012] Compared with related technologies, the underwater vehicle depth-fixed anchoring device provided by this utility model has the following advantages:

[0013] Beneficial effects:

[0014] This utility model provides a depth-fixed anchoring device for underwater vehicles. By cooperating with the underwater vehicle body and the anchoring assembly, it solves the technical problem that most existing underwater vehicle anchoring devices have relatively simple structures and different bottom-touching times after anchor release depending on the depth. If the depth of the anchor point cannot be determined and controlled independently during this process, it is easy to cause deviations in the final suspension depth, which requires further improvement. By using a servo motor to drive the reel to rotate, the release and retrieval of the anchor head can be stably performed. By using an infrared rangefinder and a reflector, the descent depth of the anchor head can be accurately determined, thereby precisely adjusting the anchoring depth to the required depth and avoiding the impact of depth deviations on the working accuracy of the underwater vehicle body.

[0015] This utility model provides a depth-fixed anchoring device for underwater vehicles. Through the setting of the anchoring component and the cooperation of the slot and the insert, the reflector can be stably connected to the outer shell. It provides effective protection for the cable when the vehicle moves, avoids the attachment and entanglement of debris such as water tanks, and reduces resistance. The overall structure is simple and stable and has good practicality. Attached Figure Description

[0022] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0023] Example 1:

[0024] like Figure 1-5 As shown, the underwater vehicle depth-fixed anchoring device of this utility model includes an underwater vehicle body 1 and an anchoring assembly 2. The anchoring assembly 2 includes an outer shell 201, the top of which is fixedly connected to the bottom of the underwater vehicle body 1. A winding reel 210 is provided inside the outer shell 201, and a cable 205 is provided on the lower side of the winding reel 210. A reflector 202 is fixedly connected to the bottom of the cable 205, and an anchoring head 203 is fixedly connected to the bottom of the reflector 202.

[0025] like Figure 1-5 As shown, the top end of the cable 205 is fixedly connected to the winding reel 210, and the cable 205 is wound around the winding reel 210.

[0026] like Figure 1-5 As shown, both ends of the winding reel 210 are fixedly connected to rollers 209, and the left end of the left roller 209 is rotatably connected to the inner wall of the left end of the outer casing 201 through a bearing 208.

[0027] like Figure 1-5 As shown, a servo motor 212 is installed inside the outer casing 201, and the right end of the right-side roller 209 is fixedly connected to the left-side output end of the servo motor 212.

[0028] During implementation, the servo motor 212 drives the reel 210 to rotate, thereby enabling the stable release and retrieval of the anchor head 203. By using the infrared rangefinder 206 and the reflector 202, the descent depth of the anchor head 203 can be accurately determined, thus allowing the anchoring depth to be precisely adjusted to the required depth, avoiding any deviation in depth that could affect the working accuracy of the underwater vehicle body 1.

[0029] Example 2:

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution for a depth-fixed anchoring device for underwater vehicles: a control module 211 is provided on the right side of the inner wall at the top of the outer shell 201, and the control module 211 is electrically connected to the servo motor 212.

[0031] like Figure 1-5 As shown, an infrared rangefinder 206 is provided on the left side of the inner wall at the top of the outer casing 201. The infrared rangefinder 206 is electrically connected to the control module 211.

[0032] like Figure 1-5 As shown, slots 207 are provided on both the left and right sides of the bottom of the outer casing 201, and inserts 204 are fixedly connected to both the left and right sides of the top of the reflector 202, with the top of each insert 204 inserted into the slot 207.

[0033] In practice, by setting up the anchoring component 2 and cooperating with the slot 207 and the insert 204, the reflector 202 can be stably connected with the outer shell 201, providing effective protection for the cable 205 when the vehicle moves, avoiding the attachment and entanglement of debris such as water tanks, while reducing resistance. The overall structure is simple and stable and has good practicality.

[0034] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0035] 1. The servo motor 212 drives the reel 210 to rotate, which can stably release and retrieve the anchor head 203. The infrared rangefinder 206 and reflector 202 can accurately determine the descent depth of the anchor head 203, so that the anchoring depth can be precisely adjusted to the required depth, avoiding the impact on the working accuracy of the underwater vehicle body 1 due to depth deviation.

[0036] 2. The slot 207 and the insert 204 work together to make the reflector 202 and the outer shell 201 stably connected, providing effective protection for the cable 205 when the vehicle moves, avoiding the attachment and entanglement of debris such as water tanks, and reducing resistance. The overall structure is simple and stable and has good practicality.

[0037] In this technical solution, after the underwater vehicle body 1 reaches the working position, the servo motor 212 drives the rotating roller 209 to rotate, and the rotating roller 209 drives the winding reel 210 to rotate. At this time, the anchor head 203 causes the reflector 202 to sink due to its own weight. The reflector 202 sinks stably through the uniform winding and unwinding of the cable 205. At this time, the infrared rangefinder 206 works to illuminate the top of the reflector 202 for distance measurement. Through cooperation with the control module 211, the descent depth of the anchor head 203 is precisely controlled. When the underwater vehicle body 1 finishes working and restarts to leave, the servo motor 212 drives the winding reel 210 to rotate and wind up the cable 205, causing the reflector 202 to rise and drive the insert 204 to be inserted into the slot 207, so that the reflector 202 is stably connected to the outer shell 201.
