Abstract
The invention relates to a positioning compensation device for the underwater measurement of a ship, belonging to the field of positioning compensation devices carrying out underwater measurement in the states of transverse rolling, vertical oscillation, and the like of the ship. The positioning compensation device is provided with a sighting bar supported by a bracket; one end of the sighting bar is sequentially connected with an elastic compensating mechanism, a compensating tool rest, a connecting disc, a connecting rod, a measuring apparatus fixing fame and an oscillation stop plate, and the other end of the same is provided with a counter weight. When the ship transversely or longitudinally rolls, mutually perpendicular tool edges of the compensating tool rest can enable a measuring apparatus to be in an upright state all the time; meanwhile, the oscillation stop plate and the elastic compensating mechanism are combined to play a role of greatly slowing down the up-and-down motion of the measuring apparatus so as to enable the measuring apparatus to be in a relative static state; and when sea currents generate at sea, a measured object can move with sea currents along a same direction when measured, a sighting mechanism plays a role of enabling a measured object to be positioned in a measuring center all the time and can carry out control by changing the position of the measuring apparatus at a small angle within a certain range, therefore the accuracy of measurement is enhanced.
Description
Technical field
The present invention relates to a kind of underwater survey peculiar to vessel location compensating device, the location compensating device technical field that belongs at ship rolling, carries out underwater survey under the state such as swing that hangs down.
Background technology
Boats and ships are placed oneself in the midst of on the sea; Except the ahead running that propelling unit own produces, also receive the influence of multiple marine environment factor, comprise the synergy of wind, wave, stream; Thereby produce the deletrious motion of stability of ship, comprise rolling, pitching, hang down and motion such as swing.
Because the motion that boats and ships self exist, the measurement activity of on boats and ships, carrying out will inevitably receive certain interference.Be fixed in the sonar detection device under the foreign water on the shipowner deck; Because will be in certain degree of depth; Press certain orientation, angular emission sonar detection signal, it must receive the influence of boats and ships displacement, if it is excessive to move; Then possibly cause sonar signal to contact not test object, and receive not any signal.Existing measurement mechanism is; Be fixed on topside to measurement mechanism, when boats and ships produce bigger roll and pitch, about measurement mechanism will inevitably produce thereupon, the motion of all around; Be difficult to realize location survey; Simultaneously, have ocean current to exist if measure the marine site, measured object maybe be with the stream measured zone of moving out of.Therefore, design a kind of device, can guarantee that the position of underwater measurement devices, angle do not change with the boats and ships displacement, perhaps, make its amount of exercise minimum, thereby realize being fixed in the accurate location survey of the boat-carrying underwater measurement devices on the ship.
Summary of the invention
For the position that guarantees the outboard underwater measurement devices, the stability of angle; The present invention provides a kind of underwater survey peculiar to vessel location compensating device; Position, the angle of this location compensating device reply measurement mechanism change carries out real-Time Compensation; And adopt the segmentation assembling mode, can make things convenient for installation, dismounting and easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of underwater survey peculiar to vessel location compensating device, the measuring instrument that is in water is fixed on the support on the ship deck through bindiny mechanism.Said bindiny mechanism is provided with a sighting bar by bracket supports, connects an elastic compensating mechanism, compensating cutting tool carriage, terminal pad, pipe link, measuring instrument fixed mount successively and only swings plate at an end of sighting bar, is provided with a counterweight at the other end of sighting bar.The 4th hanger on the said sighting bar and second hanger in the elastic compensating mechanism are in the hinge connection; The edge of a knife on the 3rd hanger hole in the elastic compensating mechanism and the compensating cutting tool carriage becomes contact to be connected to the two ends of lower connecting rod; The edge of a knife on the compensating cutting tool carriage becomes contact to be connected to the two ends of upper connecting rod with the first hanger hole on the terminal pad; Lean on flange to connect the pipe link of some in the bottom of terminal pad, the said measuring instrument fixed mount of captive joint and only swing plate in the bottom of pipe link.
On said sighting bar, be provided with a back sight and a foresight, between back sight and foresight, be provided with a supporting revolving shaft that is vertically fixed on the sighting bar.
2～6 pilot bars of said elastic compensating mechanism's employing are fixed on the guiding pole socket; At the positioning disk that spring is housed on the pilot bar and on pilot bar, slides; The two ends of spring are fixed on positioning disk and the guiding pole socket; On positioning disk, be provided with second hanger, on the guiding pole socket, be provided with the 3rd hanger with the 3rd hanger hole with the second hanger hole.
Said compensating cutting tool carriage on a circular cylinder, be provided with a mutually perpendicular edge of a knife to lower connecting rod and an edge of a knife to upper connecting rod, all be provided with edge of a knife section and cotter-pin hold to the lower connecting rod and the edge of a knife to the two ends of upper connecting rod at the edge of a knife.
Said terminal pad adopts rectangular configuration, and is provided with first hanger with the first hanger hole, is provided with a circular hole and flange is used connecting bore in the central authorities of rectangular configuration.
The invention has the beneficial effects as follows: this underwater survey peculiar to vessel location compensating device is provided with a sighting bar by bracket supports; End at sighting bar connects an elastic compensating mechanism, compensating cutting tool carriage, terminal pad, pipe link, measuring instrument fixed mount successively and only swings plate, is provided with a counterweight at the other end of sighting bar.After each detail assembly finished, measuring instrument is fixed on the instrument fixed mount, integral body is put into water then; When boats and ships produce rolling or pitching, compensating cutting tool carriage generation effect, mutually perpendicular edge of a knife mutual action; Can make instrument be in vertical state, just angle does not change, simultaneously always; Only swing plate and the synergy of elastic compensating mechanism, can slow down the up-and-down movement of instrument greatly, thereby make instrument position, angle all be in a static relatively state; The effect of pointing device is when there is ocean current at the sea; The object that will measure can be when measuring with ocean current toward a direction motion; Sighting device is in order to let Measuring Object be in measuring center all the time; The position of low-angle change instrument is controlled within the specific limits, thereby improves the accuracy rate of measuring.
