The invention discloses a negative pressure arraying device for a detecting array, which comprises a machine body and two winders (1), wherein the two winders (1) are arranged at the two ends of the machine body respectively; the machine body comprises pipe orifice cone sealing mechanisms (2), a vacuum pump (4), fixed supports (5) and an outer pipe (3) for accommodating a fiber optic hydrophone set (7) and an outer sheath (6); the pipe orifice cone sealing mechanisms (2) are arranged at the two ends of the outer pipe (3) respectively; the outer pipe (3) is supported by the supports (5); and the winders (1) are used for pulling the fiber optic hydrophone set (7) by a rope body to allow the fiber optic hydrophone set (7) to be distributed in the outer sheath (6) which is arranged in the outer pipe (3) in advance. The device further comprises the the vacuum pump (4) used for vacuumizing and connected with an extraction opening formed in the outer pipe by a pipeline. The negative pressure arraying device for the detecting array has the characteristics that the device is simple in structure, low in manufacturing cost and high in cabling arraying efficiency, and is applicable to large-scale and slender array forming.
Description
technical field [0001] The invention relates to a detection base array negative pressure array forming device, which belongs to the field of optical fiber hydrophone irrigation and cable formation engineering. Background technique [0002] The fiber optic hydrophone is a new underwater sounding sensor. Compared with the traditional piezoelectric transducer, the fiber optic hydrophone unit has the characteristics of high sensitivity, no need for impedance matching, essentially anti-electromagnetic interference and structural diversity; The fiber optic hydrophone array has the advantages of long transmission distance and wide transmission frequency. Optical fiber hydrophone systems are widely used in channel survey, fish detection, seabed geological survey and so on. Due to the urgent need of human beings to develop and utilize marine resources, the optical fiber hydrophone system has been developed unprecedentedly. However, due to the relatively late start of research on fi...
