Abstract
A vertical and horizontal vibration isolation type hydrophone structure comprises a hydrophone. The hydrophone structure is characterized in that the back end of the hydrophone and a lower support are vulcanized as a whole through a vertical vibration isolation rubber, and a hole is formed on the vibration isolation rubber for the outlet line of the hydrophone to extend out. The utility model has the advantage of simple structure and obvious vibration prevention effect, improves the strength of the hydrophone, and effectively reduces influence of the environment on the receiving effect of the hydrophone.
Description
Technical field
The utility model belongs to the underwater acoustic measurement device.
Background technology
Usually when carrying out underwater acoustic measurement, nautical receiving set can be placed into and receive acoustic emission signal under water.The generalized case nautical receiving set can be fixed on certain pedestal, and the vibration of pedestal is very big sometimes, can the reception of nautical receiving set be exerted an influence.
The utility model content
The purpose of this utility model is to the influence of nautical receiving set when reducing pedestal vibration itself or extraneous factor and influence the pedestal generation and vibrate.
A kind of hydrophone structure of vibration isolation type in length and breadth is made of nautical receiving set, it is characterized in that the rear end of described nautical receiving set is sulfided into one by vertical vibration isolation rubber and undersetting, and individual hole is arranged on the vibration isolation rubber, and the output line of nautical receiving set is stretched out.
The front end of described nautical receiving set is with the vibration isolation gas ket.
Outside the described vibration isolation gas ket and the lower carriage outside is with a mount pad, is with bolted between mount pad and the lower carriage.
The utility model is simple in structure, and vibration-isolating effect is obvious, has not only improved the intensity of nautical receiving set, has also reduced the influence of environment to the nautical receiving set reception effectively.
Description of drawings
Fig. 1, the utility model structural representation.
Wherein, 1 is nautical receiving set, and 2 is horizontal vibration damping washer, and 3 is vertical vibration isolation rubber, and 4 is lower carriage, and 5 is mount pad.
Embodiment
A kind of hydrophone structure of vibration isolation type in length and breadth is made of nautical receiving set 1, it is characterized in that, the rear end of described nautical receiving set 1 is sulfided into one by vertical vibration isolation rubber 3 with undersetting 4, and 2 holes are arranged on the vibration isolation rubber 3, and the output line of nautical receiving set 1 is stretched out.
The front end of described nautical receiving set 1 is with vibration isolation gas ket 2.
Outside the described vibration isolation gas ket 2 and lower carriage 4 outsides are with a mount pad 5, are with bolted between mount pad 5 and the lower carriage 4.
Mount pad is fixed on the pedestal, vulcanized rubber between nautical receiving set body and the lower carriage has separated the vibration that pedestal transmits, laterally vibration damping washer had both played the effect of horizontal vibration isolation, again nautical receiving set there is the supplemental support effect, thereby the intensity of nautical receiving set is improved, also effectively reduces the influence that seat vibration brings.
