Description
Technical field
The invention belongs to sonar technology, and in particular to a kind of unpowered sonar for being applied to helicopter and ship sonar operation
Launch retracting device.
Background technology
Sonar unit enters target acquisition in water-filling by sound echo, is widely used in making in the water of helicopter and ship
Industry.Because sound wave is in water transmission resistance, in order to improve sonar contact performance, when sonar works, deployed sonar antenna as far as possible.
Existing sonar generally requires external force means can just be launched, and be difficult to pack up after having worked, therefore structure is multiple
It is miscellaneous, influenceed greatly by extraneous factor, reliability is low.
The content of the invention
Technical purpose of the invention is：A kind of unpowered sonar that can effectively improve sonar contact precision and scope is provided
Launch retracting device.
The technical scheme is that：A kind of unpowered sonar launches retracting device, and it includes balance cylinder, push rod, determines
Hyte part, piston, safety spring, wherein, piston is arranged in balance cylinder, and balance cylinder is arranged in sonar housing, push rod
One end connects piston, and the other end is hinged through balance cylinder with sonar antenna, safety spring one end connection push rod, other end connection
Sonar inner walls, the positioning component is elastic component, is arranged on sonar housing sidewall, and through balance cylinder location hole and work
Plug wall extruding contact.
The piston has a hollow tubular structure.
Safety spring is divided into some groups, is symmetricly set on pusher bar support.
The positioning component contact jaw is tapered end.
In sonar input water, effect of water pressure is more than device gravity, safe bullet on piston in designated depth water pressure
Spring force and when making a concerted effort of balance cylinder damper power, piston upward movement progress push rod in balance cylinder is moved upwards, is opened
Sonar antenna, treats that sonar antenna is fully deployed, positioning component action, and piston is positioned, and makes sonar antenna keep being fully deployed shape
State carries out operation；
When operation is completed, sonar unit lifting, reach designated depth device gravity and safety spring elastic force make a concerted effort it is big
Water pressure, the spacing resistance of positioning component and when making a concerted effort of balance cylinder damper power, sonar antenna is packed up.
The solution have the advantages that：Sonar antenna of the invention launches the pressure by water as main driving force, drives
Sonar antenna launches, and is positioned by positioning component, keeps deployed condition；Sonar antenna is packed up by safety spring and gravity
Drive, drive sonar antenna to pack up, safety spring makes antenna keep collapsed state, so as to balance each work by balance cylinder
Firmly, device is realized unpowered expansion and is packed up, the investigative range and precision of sonar are effectively increased, with larger
Actual application value.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is referred to, unpowered sonar of the invention launches retracting device includes balance cylinder, push rod, positioning component, work
Plug, safety spring.Wherein, the piston is arranged in balance cylinder, and balance cylinder is arranged in sonar housing.The push rod one
End connection piston, the other end is hinged through balance cylinder with sonar antenna.
The safety spring is divided into some groups, and one end is connected on pusher bar support, and is symmetrical arranged around push rod, to avoid
Interfered with sonar antenna, other end connection sonar inner walls.The positioning component is elastic component, is arranged on sonar housing
Side wall, and contacted with piston wall extruding through balance cylinder location hole, wherein, the positioning component contact jaw is tapered end, with
Facilitate piston press return.
In addition, the piston has a hollow tubular structure, to facilitate positioning component to position piston.
During sonar expansion retracting device real work that the present invention is unpowered.
During sonar is put into water by helicopter or ship by cable, effect of water pressure on piston, in designated depth water
More than device gravity, safety spring elastic force and other damping forces when making a concerted effort, motion is pushed away piston pressure upwards in balance cylinder
Dynamic push rod is moved upwards, opens sonar antenna, treats that sonar antenna is fully deployed, positioning component action, and piston is positioned, and makes sonar
Antenna holding its fully unfolded position carries out operation.
When operation is completed, sonar unit lifting, reach designated depth device gravity and safety spring elastic force make a concerted effort it is big
Making a concerted effort for water pressure, the spacing resistance of positioning component and other damping forces, sonar antenna is packed up, and safety spring makes collapsed state steady
It is fixed.The relation between each power is balanced by using suitable gas pressure in balance cylinder, device is realized.
Sonar antenna of the invention launches the pressure by water as main driving force, drives sonar antenna to launch, by fixed
Hyte part is positioned, and keeps deployed condition；Sonar antenna is packed up by safety spring and weight-driven, drives sonar antenna to receive
Rise, safety spring makes antenna keep collapsed state, so as to balance each active force by balance cylinder, realizes device
It is unpowered to launch and pack up, the investigative range and precision of sonar are effectively increased, with larger actual application value.
