Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the marine acoustic passive receiving device that is used for combining the vector scalar hydrophone in the prior art, it is troublesome to adjust the position of the hydrophone in use, and it is necessary to adjust the depth of the whole device in the sea, if the device The deeper the diving depth, the greater the pressure caused by the seawater pressure on the device, which will affect the normal operation of the device, and the deeper the diving depth of the device, the greater the impact of the water flow on the device. At the same time, the existing device During the lifting process, due to the high water pressure, the seawater is easy to exert pressure on the device when it rises, causing greater pressure on the traction facilities of the hoisting device, and the device itself will also be damaged. The proposed combination vector Marine Acoustic Passive Receiving System and Using Method of Scalar Hydrophone

Embodiment 1

[0043] see Figure 1-7 , the present invention provides a technical solution: a marine acoustic passive receiving system combined with a vector scalar hydrophone, comprising a fixed block 1, a fixed cylinder 2, a protection mechanism 3, a positioning mechanism 5 and an adjustment mechanism 7, the upper surface of the fixed block 1 is fixed The fixed cylinder 2 is connected, and the outer side of the fixed cylinder 2 is provided with a protective mechanism 3. The protective mechanism 3 includes a sleeve 31 sleeved on the outer side of the fixed cylinder 2. The lower surface of the sleeve 31 is fixedly connected with a conical cover 32. The conical cover 32 is located on the upper side of the fixed block 1, the upper surface of the conical cover 32 is clamped with a first threaded cap, the first threaded cap is internally threaded with a first threaded post 33, the top of the first threaded post 33 The stopper 4 is fixedly connected, the bottom end of the first threaded column 3...

Embodiment 2

[0050] The method for using the marine acoustic passive receiving system combined with the vector scalar hydrophone specifically includes the following steps:

[0051] S1, control the hydrophone 6 to change its depth in seawater, the second motor 71 can drive the second threaded column 77 to rotate through the first rotating shaft 72 when the second motor 71 is working, and the first rotating shaft 72 can rotate stably under the action of the first bearing, The second threaded cap can move up and down and drive the rack 73 to move up and down through the L-shaped rod 78. When the rack 73 moves up, it drives the gear 75 to rotate. Under the action of the first rotating shaft 72 and the first bearing, the gear 75 can rotate stably. 75 can drive the hydrophone 6 to move and adjust its position through the gas cylinder 51 and the fixed rod 52;

[0052] S2. When the electric push rod 59 is controlled to work, the electric push rod 59 stretches and simultaneously pushes the push blo...

Abstract

The invention discloses a marine acoustics passive receiving system combined with a vector scalar hydrophone and a use method. The marine acoustics passive receiving system comprises a fixing block, a fixing cylinder, a protection mechanism, a positioning mechanism and an adjusting mechanism, wherein the upper surface of the fixing block is fixedly connected with the fixing cylinder, the outer side of the fixing cylinder is sleeved with the protection mechanism, the lower side of the protection mechanism is provided with the adjusting mechanism, the adjusting mechanism is arranged in the fixing block, and a positioning mechanism is arranged on the adjusting mechanism. According to the system, the adjusting mechanism is arranged, when a second motor works, a second threaded column can be driven to rotate through a first rotating shaft, the first rotating shaft can stably rotate under the action of a first bearing, and a second threaded cap can move up and down and drives a rack to move up and down through an L-shaped rod; the gear can drive the hydrophone to move and adjust the position of the hydrophone through the air cylinder and the fixing rod, so that the depth of the hydrophone in seawater can be effectively changed, the hydrophone does not need to be adjusted by controlling traction equipment, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of ocean acoustics, and in particular relates to an ocean acoustic passive receiving system and a using method. Background technique [0002] Ocean acoustics is the science of studying the law of sound waves propagating in the ocean and using sound waves to detect the ocean. It is a marginal subject of oceanography and acoustics. Due to the influence of solar radiation heating and wind agitation, the vertical distribution of seawater temperature is generally in a layered structure. Coupled with the influence of pressure, the speed of sound in the ocean is vertically distributed. The sound wave emitted from the place with the lowest sound speed is refracted due to the difference in the sound speed of the upper and lower layers, and the sound rays reflecting the sound wave propagation path always bend to the place with the lowest sound speed. Most of the sound waves undergo such reciprocating bending and refr...
