Description

Technical Field

[0001] The present invention relates to the technical field of underwater communication and underwater detection equipment, and in particular to a pressure-resistant cabin sealing assembly and a manufacturing method thereof. Background Art

[0002] In the field of underwater communication and underwater detection, the performance of the hydroacoustic transducer, as the main device for transmitting and receiving acoustic signals, is crucial to the entire communication and detection system. Usually, multiple groups of array elements are designed in a certain formation inside the hydroacoustic transducer, and then the output lines of each array element are gathered together, and after external polyurethane vulcanization, a watertight cable with a watertight plug is formed. The hydroacoustic transducer is usually used with a pressure-resistant cabin, which contains a series of power supply, control and processing circuits. The pressure-resistant cabin is usually designed with a watertight socket on one side of the end cover. After the hydroacoustic transducer is connected to the pressure-resistant cabin through a watertight plug and a watertight socket, the cabin circuit can control the transducer, and the functions of transmitting, receiving, processing and storing hydroacoustic signals can be realized.

[0003] With the continuous development of underwater communication and detection technology, in order to improve the communication distance or improve the detection accuracy, the number of array elements of the hydroacoustic transducer is constantly increasing. The increase in the number of array elements directly leads to an increase in the number of external lines of the hydroacoustic transducer, which increases the diameter of the watertight cable from the hydroacoustic transducer and its minimum bending radius accordingly; at the same time, due to the increase in the number of outgoing lines, the size of the watertight plug on the hydroacoustic transducer and the watertight socket on the pressure-resistant hull also increases accordingly. This increase in size has a great impact on some products with strict diameter requirements. Due to the limitation of the product diameter, the bending radius of the watertight cable installed on the watertight socket at the end cover of the transducer is smaller than the minimum bending radius allowed by itself, which reduces the long-term reliability of the watertight cable.

[0004] Therefore, it is urgent to propose a pressure-resistant cabin sealing assembly and a manufacturing method thereof to solve the problems raised. Summary of the invention

[0058] S3. Installing the transducer 100 equipped with the watertight socket 300 on one side of the pressure-resistant cabin 200 can realize the through-cabin routing of a large number of array elements. The watertight socket 300 is electrically connected to the transducer 100 and the pressure-resistant cabin 200 through the array element cable 101 and the movement cable 201 respectively, reducing the intermediate connecting cables, effectively avoiding the conventional design of using watertight cables and watertight plugs for underwater acoustic transducers, solving the problem of large bending radius required for thicker watertight cables, and thus ensuring the long-term reliability of watertight cables; in addition, by reducing the intermediate connecting cables, the installation space is greatly reduced and the space utilization rate is improved; while ensuring the effective bending radius of the cable, the number of wire harnesses is greatly increased, and the amount of data collected is effectively increased; the installation position is flexible. Under certain conditions, multiple transducers 100 can be installed on the side of the pressure-resistant cabin 200 at the same time, so that multiple devices can work together and the work efficiency is greatly improved; compared with the through-cabin design at the end cover 220, the overall size of the equipment is effectively reduced, the equipment is miniaturized and modularized, and the equipment is more integrated.

[0059] Specifically, after the watertight socket 300 is integrally connected to the transducer 100, the movement cable 201 on the other side of the watertight socket 300 passes through the second pairing interface 202 of the pressure-resistant cabin 200 and is electrically connected to the electronic movement in the pressure-resistant cabin 200. When the transducer 100 equipped with the watertight socket 300 is installed on one side of the pressure-resistant cabin 200, a large number of array elements can be routed through the cabin. The watertight socket 300 is electrically connected to the transducer 100 and the pressure-resistant cabin 200 through the array element cable 101 and the movement cable 201, respectively, reducing the intermediate connecting cables, effectively avoiding the conventional design of using watertight cables and watertight plugs for underwater acoustic transducers, solving the problem of a larger bending radius required for thicker watertight cables, and thereby ensuring the long-term reliability of the watertight cables. In this embodiment, installing the movement cable 201 into the pressure-resistant cabin 200 is a common technique for those skilled in the art and need not be elaborated here.

[0060] The pressure-resistant cabin 200 is provided with a fifth fixing hole 205 around the second docking port 202 , and the first fastener 401 is passed through the groove 1131 , the second fixing hole 121 and the first fixing hole 311 and then fixed in the fifth fixing hole 205 , thereby further fixing the transducer 100 and the watertight socket 300 .

[0061] In summary, a pressure-resistant cabin sealing assembly and a manufacturing method thereof of the present invention arranges a transducer 100 on one side of a pressure-resistant cabin 200, forms an accommodation space between the transducer 100 and the pressure-resistant cabin 200, places a watertight socket 300 in the accommodation space, and connects an array element cable 101 to one side of the watertight socket 300, and connects a movement cable 201 to the other side of the watertight socket 300, thereby reducing intermediate connecting cables, effectively avoiding the conventional design of using watertight cables and watertight plugs for underwater acoustic transducers, solving the problem of a larger bending radius required for thicker watertight cables, and thereby ensuring the long-term reliability of the watertight cables.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
