Description
Technical field
The utility model relates to a kind of hydrological survey device, particularly a kind of marine telescope current surveying device.
Background technology
In recent years, along with the develop rapidly of ADCP current measured technology and constantly popularizing at home, adopt ADCP to carry out the important symbol that boating type discharge measurement has become discharge site modernization level, especially can make up the blank of a lot of special sections in discharge measurement data.But because ADCP is unpowered equipment, need to draw by being arranged on the support surveyed on ship, its need to meet in flow measurement process below three necessary conditions: one is that underwater penetration under water of popping one's head in will be fixed and can not surface; Two is that installation site will be avoided surveying ship to the interference of flow-shape as far as possible; Three is can not occur cavitation corrosion or whirlpool at probe lower surface.
Survey the flow measurement support on ship for the hydrology, domestic scholars proposes some design and installation schemes.Such as Chinese patent " hydrology detecting instrument universal mount ", the patent No. is 201420124078.X, the device provides a kind of hydraulically powered hydrology detecting instrument universal mount, be made up of base, column, swing arm, hoist cylinder, piston rod and directed follow up lever etc.The commonality of this support is comparatively strong, installation is firm and degree of automation is higher, but equipment fixed installation occupies larger space above deck, and probe fixed installation on the piston rod, along with the underwater penetration of the hunting probe of survey ship is not easily fixed and easily surfaces.Again such as in Chinese patent " a kind of float type adaptive supporting frame of measurement instrument ", the patent No. is 201420402701.3, and this device, by being hinged on the floating shelf on link span, makes the underwater penetration that probe can keep fixing.But when the design of its blunt form fails to solve high flow rate of water flow there is the key issue of cavitation corrosion or whirlpool in probe lower surface, and this support needs dismounting, and degree of automation is not high.
The general character of several support is above: one is three necessary requirements that can not all meet needed for instrument, can cause Instrument working state exception or data distortion to some extent; Two is that support or fixed installation occupy between deck space, or needs dismounting to waste time and energy, and lacks satisfactory to both parties plan.
Summary of the invention
The purpose of this utility model is to solve the problem that can not meet the requirement of accurate flow measurement in existing flow measurement support flow measurement process peculiar to vessel, provides a kind of marine telescope current surveying device.
The utility model solves the technical scheme that its technical matters adopts: a kind of marine telescope current surveying device, comprise survey ship, the deck of described survey ship is provided with the expansion link that can cross out ship side, the outer end of described expansion link is connected with the trimaran swum on the water surface by front haulage rope, described trimaran is provided with current measuring instrument, described front haulage rope connects the fore of trimaran, and the stern of trimaran is also connected with survey boat deck by rear haulage rope.This device draws trimaran by expansion link, ensures that current measuring instrument maintains enough transverse distances with survey ship, avoids surveying ship to the disturbing influence measurement accuracy of flow-shape; Adopt trimaran to swim on the water surface and carry current measuring instrument, trimaran draft is stablized thus is ensured that current measuring instrument enters the stability of water, and trimaran adopts highly faired hull design, little to current flow resistance, not easily forms cavitation corrosion or whirlpool.Meanwhile, this device arranges hauling rope respectively in the front and back of trimaran, ensures trimaran attitude stable in water.Therefore, adopt this device that current surveying device is installed, can ensure that boating type measures the accurate and stable of flow measurement data.
As preferably, the outer end of described expansion link is provided with can the lifting bar of up-down adjustment, and the bottom of described lifting bar is provided with wire rope handling ring, front haulage rope one end be fixed on survey on boat deck, the other end is through the fore connecting trimaran after wire rope handling ring.Regulate the height of lifting bar according to flow rate of water flow and the relative velocity surveying the ship speed of a ship or plane, when relative velocity is too high time, force down lifting bar, avoid trimaran fore to tilt.
As preferably, the survey ship ship side of described expansion link position thickeies, and lateral surface and lifting bar correspondence position offer vertical storage tank on the quarter.Within the complete retraction ship side outline of end energy when regaining of expansion link, lifting bar can be included in storage tank simultaneously, receives ship side protection.
As preferably, after one end chevron pointing bifurcated that described front haulage rope is connected with trimaran, connect the both sides of trimaran fore respectively.
As preferably, described rear haulage rope connects trimaran stern near the side surveying ship.The cooperation traction of front haulage rope, rear haulage rope can ensure trimaran attitude stabilization.
As preferably, described trimaran has three parallel hulls, and hull is airflow design, and three parallel hull common support have an equipment platform.
As preferably, be provided with sleeve pipe outside described expansion link, described sleeve pipe is embedded on the deck surveying ship, and sleeve pipe height is no more than deck surface.Such setting does not take between deck space, and convenient operation personnel take action.
As other preferred version, outside described expansion link, be provided with sleeve pipe, described sleeve pipe be fixed on survey ship deck on and higher than deck surface.This set is changed little to survey boat deck, and sleeve pipe height is no more than 20cm, little on operating personal action impact.
As preferably, described expansion link adopts hydraulic power to drive.
As preferably, described trimaran and front haulage rope, rear haulage rope junction all adopt antifriction clasp, and antifriction clasp is made up of ganoid cylindrical aluminium alloy.
The utility model adopts expansion link to ensure, and current measuring instrument has enough transverse distances with survey ship ship side, avoid surveying ship to disturb flow-shape, by trimaran ensure current measuring instrument enter water the degree of depth stablize, reduced the generation of cavitation corrosion or whirlpool by the highly faired hull of trimaran, ensure that the accuracy of flow measurement data; And by the cooperation of front and back hauling rope, ensure that trimaran is advanced the stable of attitude.
