Description

Technical Field

[0001] The invention relates to a retractable device structure, in particular to a retractable device for underwater monitoring vector hydrophone. Background Art

[0002] With the development of underwater acoustic technology, vector hydrophones, as a type of measurement sensor for obtaining acoustic vector component information of underwater sound fields, have been applied in many fields. Compared with traditional acoustic pressure hydrophones, vector hydrophones have the advantage of being able to obtain more sound field information. When used in sonar buoys or acoustic arrays, they can improve the detection and positioning capabilities of sonar.

[0003] A Chinese patent discloses a vector hydrophone with the authorization announcement number CN214538229U, which adopts an "oil seal" structure design, encapsulates the composite acoustic sensor in a sound-transmitting sealed cavity, and suspends and installs the composite acoustic sensor through a spring with a pre-set elastic coefficient, so that the suspension system and the composite acoustic sensor become a whole and are sealed inside the "oil seal" structure. When in use, it can be rigidly fixed to the platform directly through the screw holes on the upper and lower end covers, avoiding performance instability caused by disassembly or replacement of the spring. However, according to the above-mentioned drawings in the specification and the actual application scenarios of the vector hydrophone, it can be seen that: since the cable on the vector hydrophone is relatively long, a part of the cable goes into the water with the vector hydrophone for operation, while the other part of the cable is exposed to the outside, which not only easily causes the working area to be messy, but also is not conducive to the subsequent storage of the cables. Summary of the invention

[0004] The present invention aims to solve the above-mentioned shortcomings of the prior art and provide a retractable and fixed-length retractable device for underwater monitoring vector hydrophones.

[0006] The locking device includes a threaded rod, a mounting plate and an adjusting plate. The two ends of the mounting plate are respectively fixed on the inner sides of the first bracket and the second bracket. The adjusting plate is located at the lower part of the mounting plate. A threaded hole is provided on the mounting plate. The threaded rod passes through the threaded hole. The bottom end of the threaded rod is rotatably connected to the adjusting plate through a bearing.

[0007] A locking block is respectively arranged at two ends of the bottom of the adjusting plate.

[0008] The bottom of the locking block is provided with an arc-shaped slot, which matches the shape of the top of the winding drum and is located directly above the winding drum.

[0011] A plug hole is arranged on the front surface of the winding drum, and the plug hole matches with the connector, and the diameter of the connector is smaller than the diameter of the plug hole.

[0012] The beneficial effects of the present invention are: the structure of the present invention can store the cables by winding the cables around the outside of the winding drum, preventing the long cables from causing problems such as clutter in the working area. A lock is provided to fix the winding drum to prevent loosening, thereby ensuring the normal use of the vector hydrophone body.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] As shown in the figure, the retractable device for underwater monitoring vector hydrophone includes a bracket, a stopper 4, a winding drum 5 and a cable 52. The bracket includes a first bracket 1 and a second bracket 2. The stopper 4 and the winding drum 5 are fixed between the first bracket 1 and the second bracket 2. The stopper 4 is located above the winding drum 5. The cable 52 is wound on the winding drum 5. The two ends of the cable 52 are respectively connected to the fixed vector hydrophone body 53 and the connector 54. A transmission shaft 6 is provided in the winding drum 5. The transmission shaft 6 passes through the first bracket 1, and one end of the transmission shaft 6 is rotatably connected to the second bracket 2 through a bearing. The transmission shaft 6 is rotatably connected to the first bracket 1 through a bearing. A plug hole 51 is provided on the front surface of the winding drum 5. The plug hole 51 matches the connector 54, and the diameter of the connector 54 is smaller than the diameter of the plug hole 51. By winding the cable 52 around the outside of the winding drum 5, the cable 52 can be stored to prevent the cable 52 from being too long and causing problems such as a cluttered working area. Moreover, the cable 52 can be reeled in and released by the forward and reverse rotation of the winding drum 5, which facilitates moving the vector hydrophone body 53 to the underwater area for operation, making the vector hydrophone body 53 more convenient and quick to use. At the same time, the vector hydrophone body 53 can also be stored after use to prevent problems such as the vector hydrophone body 53 being lost. In the actual detection process, this method does not require manual labor to hold the cable all the time, which reduces the workload of the staff and is conducive to the actual reeling and releasing of the cable.

[0019] The stopper 4 includes a threaded rod 42, a mounting plate 41 and an adjustment plate 43. The two ends of the mounting plate 41 are respectively fixed to the inner side of the first bracket 1 and the second bracket 2. The adjustment plate 43 is located at the lower part of the mounting plate 41. The mounting plate 41 is provided with a threaded hole. The threaded rod 42 passes through the threaded hole. The bottom end of the threaded rod 42 is rotatably connected to the adjustment plate 43 through a bearing. A locking block 44 is provided at each end of the bottom of the adjustment plate 43. The bottom of the locking block 44 is provided with an arc-shaped card groove, which matches the shape of the top of the winding drum 5. The arc-shaped card groove is located directly above the winding drum 5. Slide blocks 45 are provided at both ends of the adjustment plate 43. The inner side of the first bracket 1 and the second bracket 2 is provided with a slide groove 3. The slide block 45 is embedded in the slide groove 3 and slides up and down in the slide groove 3. The stopper 4 can fix the winding drum 5 to prevent the winding drum 5 from loosening after the cable 52 and the vector hydrophone body 53 reach the ideal depth, thereby affecting the actual normal underwater detection, and ensuring the normal use of the vector hydrophone body 53.

[0020] When using the device, insert one end of the connector 54 into the socket 51, then hold one end of the transmission shaft 6 and rotate it forward, at this time, the cable 52 can be wound around the outside of the winding drum 5, and then hold the threaded rod 42 and rotate it forward, at this time, the adjustment plate 43 and the locking block 44 can be driven to move downward until the locking block 44 contacts the winding drum 5, thereby fixing the winding drum 5. When the vector hydrophone body 53 needs to be used, first install the first bracket 1 and the second bracket 2 above the water surface to be operated, and then hold the threaded rod 42 and reverse it, at this time, the adjustment plate 43 and the locking block 44 can be driven to move upward until the locking block 44 separates from the winding drum 5, at this time the winding drum 5 is movable, and then hold One end of the transmission shaft 6 is reversed, thereby driving the winding drum 5 to reverse. At this time, the cable 52 is in a pay-out state, so that the vector hydrophone body 53 can be moved underwater for operation. Then, the threaded rod 42 is held and rotated forward, thereby driving the locking block 44 to move down and fix the winding drum 5 to ensure the normal operation of the vector hydrophone body 53. After the vector hydrophone body 53 is used, the threaded rod 42 is reversed, and the transmission shaft 6 is held and rotated forward. At this time, the cable 52 is in a take-up state, which is convenient for taking the vector hydrophone body 53 out of the water. Then, the threaded rod 42 is held and rotated forward, so that the locking block 44 fixes the winding drum 5, thereby completing the storage process.

[0021] By establishing a wire-reeling mechanism on the water surface, the cables can be stored to prevent problems such as long cables causing a cluttered working area. By releasing the wires, the sensor can slowly sink to the ideal underwater depth, which has high detection accuracy and reduces detection errors, and helps to realize the practical application of high-precision direction-finding technology of vector sensors.

[0022] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
