Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] see Figure 1-Figure 11 What is claimed is a lift-type multi-beam acoustic equipment dome for scientific research ships, comprising a fixed dome 1, a lift dome 2 and a lifting mechanism. The fixed wind deflector 1 is welded on the bottom of the hull 10, and the transducers of the multi-beam acoustic equipment are packaged in the fixed wind deflector 1 by embedded or separated installation technology; in order to prevent the impact of air bubbles on the multi-beam acoustic equipment, the fixed guide The included angle between the bow of the flow cover 1 and the incoming flow direction of the...

Abstract

The invention discloses a lifting multi-beam acoustic equipment guide cover for examination ship, which comprises a fixed flow guide cover, a lifting guide cover and a lifting mechanism. The fixing guide cover is fixed to the bottom of the ship body and the transducer of the multi-beam acoustic equipment is fixed on the fixed guide cover. The angle between the main body part of the fixed guide cover and the current flow direction is an obtuse angle; the angle between the two side plates and the bottom of the hull is an acute angle; the lifting guide cover is connected with the lifting mechanism; the angle between the lifting guide cover and the flow direction of the water flow is an acute angle; the angle between the two side plates and the bottom of the hull is an obtuse angle; the lifting mechanism drives the lifting guide cover to rise; the lifting guide cover is placed on the groove of the bottom of the ship; the bottom of the lifting guide cover is arranged to be flush with the bottom of the fixed guide cover. The invention can reduce the resistance of the multi-beam transducer guide cover and ensure the detection effect of the multi-beam acoustic equipment.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a lift-type multi-beam acoustic equipment guide cover for scientific research ships. Background technique [0002] A comprehensive marine scientific research vessel needs to install a variety of acoustic detection equipment. The transducers of the acoustic detection equipment generally work underwater, and different methods can be used for their deployment, mainly including embedded, hanging basket, shroud and Fin type. Which method to use depends on the environmental requirements of the equipment itself, the hull line and layout conditions and other factors, and cannot be generalized. Among the acoustic detection equipment, the multi-beam sounding system represents the most advanced means of surveying topography and geomorphology today. The size of the transducer varies greatly due to the difference in the detection water depth and beam angle: generally, the size of the ...
