The utility model has the technical scheme that a sonar probe anti-collision protection device of an unmanned air cushion surveying boat comprises a sonar probe rod vertically arranged at the center bottom part of an air cushion ship, wherein the top end of the sonar probe rod is provided with a sonar probe. The utility model is characterized in that the sonar probe rod is rotatablely hinged at the bottom part of the air cushion ship, the anti-collision protection device is additionally provided with a motive power mechanism capable of making the sonar probe rod fast move, the sonar probe rod is hinged on a support frame of the bottom part of the air cushion ship through a universal-joint mechanism, the center of the hinging point thereof maintains a certain distance from the bottom end of the sonar probe rod, and the motive power mechanism is an air cylinder communicated with an air source, wherein an air cylinder body is also hinged at the bottom part of the air cushion ship, the top end of an air cylinder piston rod is hinged with the bottom end of the sonar probe rod, and an air cylinder seat is hinged with the bottom part of the air cushion ship through a spherical surface hinge.
Description
Technical field
The utility model relates to a kind of anti-collision protection device, especially the Sonar Probe anti-collision protection device of driverless operation air cushion instrumentation ship.
Background technology
Huge water resources is being contained in the region, river course in the big southwest of China.Yet because with a varied topography, the riverbank is dangerously steep, The turbulent river crashes its way through, exploration during hydrologic data difficulty very big.The tradition investigation method is to carry sonar equipment with canoe, along cable wire laterally navigation on the river course, river topography is surveyed.Torrent, whirlpool are easy to canoe is toppled; Cause casualties the device damage accident.
For properly settling the problems referred to above, the contriver proposes to adopt the unmanned remote control air cushion vehicle, at the torrent surface navigation and carry out remote control exploration, can effectively avoid the influence of torrent and whirlpool and operation reposefully.Yet be installed in the crashproof problem of the Sonar Probe of air cushion vehicle bottom, it is anxious to be solved to still need.
The outstanding outward thing Anti-bumping protection of conventional bottom of ship only needs outstanding outside thing navigation the place ahead that block is set, and makes streamline slightly and handle and get final product.Since minimum to the ship's navigation influence, can ignore.But surface effect vehicle is in floating condition at the water surface, stretches into outer outstanding thing the water from ship, and the resistance of generation is to the existing considerable influence of air cushion vehicle; Increase fender guard again and certainly will increase bigger resistance, even directly have influence on the safety of navigation of air cushion vehicle, thereby be infeasible.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of air cushion vehicle Sonar Probe anti-collision protection device is provided, and this device should have can dodge obstacle, crashproof effective, the characteristics that running resistance is little rapidly.
The technical scheme that the utility model provides is: driverless operation air cushion instrumentation ship Sonar Probe anti-collision protection device, comprise a sonar feeler lever that vertically is installed in the air cushion vehicle centre bottom, and the top of sonar feeler lever is installed with Sonar Probe; It is characterized in that this sonar feeler lever is hinged on air cushion vehicle bottom rotationally, other is furnished with an actuating unit that makes sonar feeler lever rapid movement.
Described sonar feeler lever is hinged on by a universal joint mechanism on the support of air cushion vehicle bottom, and the bottom of its hinge-point center and sonar feeler lever keeps certain distance.
Described actuating unit is the cylinder that is communicated with source of the gas, and cylinder block wherein also is hinged on the air cushion vehicle bottom, and the bottom of cylinder piston rod top and sonar feeler lever is hinged.
The cylinder block of described cylinder and air cushion vehicle bottom are hinged by a spherical hinge.
The bottom of described cylinder piston rod top and sonar feeler lever is hinged by universal joint cross.
The hinge-point center of described cylinder block and air cushion vehicle bottom, and the line between the hinge-point center of cylinder piston rod top and sonar feeler lever bottom, the axis coaxle during with the vertical positioning states of sonar feeler lever.
Principle of work of the present utility model is: during normal working, the sonar feeler lever of air cushion vehicle bottom is arranged (Sonar Probe is vertically placed about the 200mm of underwater usually) straight down, and the high pressure gas compressing piston rod in the cylinder is exerted pressure to the top of sonar feeler lever; Because this moment, piston rod was to the pressure direction of sonar feeler lever and the axis coaxle of sonar feeler lever (arm of force length is zero), so piston rod is zero to the moment of sonar feeler lever, the plumbness of sonar feeler lever is stablized.When running into obstacle in the air cushion vehicle navigation process, the lower end of sonar feeler lever is laterally promoted some distances and then makes the bottom of sonar feeler lever also produce displacement toward opposite sense by obstacle, this moment, piston rod was offset the pressure direction of sonar feeler lever and the axis of sonar feeler lever, rotated the arm of force and produced immediately; Formed moment roof pressure the sonar feeler lever and is rotated, and (length by piston rod limits, and makes Sonar Probe initiatively avoid bigger bump and be protected till the sonar feeler lever is similar to level attitude.And behind clear an obstacle, only need remote control adjustment air valves (to the reverse gas transmission of cylinder) to make piston rod oppositely spur the sonar feeler lever it is rotated, be reset to straight down state again until the sonar feeler lever; After this control mechanism automatic switchover air valve, the high pressure gas in the input cylinder are oppressed piston rod once more and are again exerted pressure in the top of sonar feeler lever, and the sonar feeler lever promptly is in the triggering state for the treatment of again.
The beneficial effects of the utility model are: because set mechanism is quick on the draw, the touching obstacle initial stage automatically twirl sonar feeler lever with avoiding obstacles, can prevent the Sonar Probe damage, can keep the steady of air cushion vehicle again, guarantee the safety of navigation of air cushion vehicle reliably; And designed omnidirectional mechanism, can both react neatly in the time of can guaranteeing to run into collision in any direction.Thereby has unique Anti-bumping protection effect.
