Description

Technical Field

[0001] This utility model relates to the technical field of floating positioning devices, specifically a positioning device for underwater equipment. Background Technology

[0002] With the increasing demand for marine exploration and environmental monitoring, underwater detection equipment has become the main force in performing these tasks. For example, sonar is an electronic device that uses the propagation characteristics of sound waves underwater to complete underwater detection and communication tasks through electroacoustic conversion and information processing. It is one of the most widely used and important devices in underwater acoustics.

[0003] Currently, underwater equipment is deployed to the target area using ship hulls and underwater equipment deployment and recovery devices. To facilitate the recovery of underwater equipment, floating positioning devices are usually installed to ensure the stability of the underwater equipment's detection depth and facilitate rapid recovery later. However, the ocean has large waves and poor positioning signals. Most existing floating positioning devices rely on the BeiDou satellite positioning system for positioning and recovery. When the positioning system malfunctions, it becomes difficult to locate the underwater detection equipment, affecting the recovery progress. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the positioning device for underwater equipment according to this utility model. Please refer to [link / reference]. Figures 1-6 This embodiment provides a positioning device for underwater equipment, comprising:

[0032] Positioning float 1, with a hollow support frame 3 above the positioning float 1, a display component 4 at the top of the hollow support frame 3, and a solar panel 5 for supplying power to the display component 4 installed on the outer wall of the hollow support frame 3;

[0033] The winding reel 7 has a positioning line 9 embedded in it for connecting with underwater equipment, and the bottom end of the winding reel 7 has a second groove 24 arranged in a ring array. The bottom plate 8 for fixing the positioning line 9 is provided below the winding reel 7.

[0034] In this embodiment, in order to keep the positioning float 1 stable on the water surface, the top of the positioning float 1 is threaded with a sealing top cover 2, and the outer wall of the positioning float 1 is integrally formed with an extension plate 11 in a ring array. A balance float 6 is installed on each of the multiple extension plates 11. An energy storage battery 12 is fixed at the bottom of the cavity of the positioning float 1. A protective layer 13 is provided on the outside of the energy storage battery 12. The balance float 6 on the multiple extension plates 11 increases the contact area between the positioning float 1 and the water surface, so that the positioning float 1 can remain stable when it is impacted by the water flow. At the same time, the energy storage battery 12 embedded in the bottom of the positioning float 1 greatly reduces the center of gravity height of the positioning float 1, so that the positioning float 1 will not tip over when it is impacted by the water flow.

[0035] In this embodiment, to achieve positioning and rapid retrieval of the underwater equipment, a receiving groove 10 is provided at the center of the winding reel 7. The positioning line 9 is wound in the receiving groove 10. A tethering hole 23 is provided on the inner wall of the groove. The end of the positioning line 9 is fixed in the tethering hole 23. Fastening bolts 19 are installed in a ring array at the top of the connecting part 20. The fastening bolts 19 pass through the connecting part 20 and are threaded into the hollow support frame 3. A screw hole 22 is provided at the bottom end of the winding reel 7. A knob bolt 17 is threaded into the screw hole 22 below the bottom plate 8. Multiple first grooves 15 that match the second groove 24 are provided on the inner side of the bottom plate 8. A protruding plate 16 that is inserted into the second groove 24 is integrally formed on the outer side of the bottom plate 8. Before the underwater equipment is used, one end of the positioning line 9 is tied and fixed in the tethering hole 23, and the positioning line 9 is wound in the receiving groove 10. When the underwater equipment is used, the positioning line 9 is wound in the receiving groove 10. After the other end of the line 9 passes through the first groove 15 on the base plate 8, it is tied and fixed to the underwater equipment. When the length of the positioning line 9 released from the receiving groove 10 is sufficient to allow the movement of the underwater equipment, the positioning line 9 is moved downward into the second groove 24, and the protruding plate 16 at the top of the base plate 8 is inserted into the second groove 24. The knob bolt 17 at the bottom of the base plate 8 is threaded into the screw hole 22, so that the base plate 8 is fixed at the bottom of the winding reel 7. The knob bolt 17 is preferably made of a corrosion-resistant rigid material such as plastic. Multiple protruding plates 16 are set on the outside of the base plate 8 to prevent the positioning line 9 connected to the underwater equipment from slipping out of the second groove 24. After multiple protruding plates 16 are inserted into the second groove 24, the protruding plates 16 are interference-fitted with the inner wall of the second groove 24, so that the protruding plates 16 are fixed in the second groove 24. Even if the knob bolt 17 becomes loose, the base plate 8 and the protruding plates 16 can still be fixed at the bottom of the winding reel.

[0036] In this embodiment, in order to make the positioning float 1 visible from a distance, the display component 4 of this application includes a lighting lamp 21 and a waterproof cover 18 sleeved on the outside of the lighting lamp 21. The bottom end of the waterproof cover 18 is integrally formed with a connecting part 20. A waterproof wire 14 is embedded between the hollow support frame 3 and the positioning float 1. The energy storage battery 12 is electrically connected to the lighting lamp 21 and the solar panel 5 through the waterproof wire 14. The electricity generated by the solar panel 5 is stored in the energy storage battery 12. The energy storage battery 12 is also equipped with accessories such as a photovoltaic inverter for converting electrical energy. The principle and accessories of the solar panel 5 supplying power to the energy storage battery 12 are existing technologies and will not be described in detail here. The solar panel 5 can continuously supply power to the energy storage battery 12, thereby greatly increasing the lighting time of the lighting lamp 21. The four solar panels 5 on the side wall of the hollow support frame 3 can meet the power supply of the lighting lamp 21, and the lighting lamp 21 can be illuminated for 24 hours during the day when the sunlight is good.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
