Description
Technical field
The utility model relates to a kind of hydrological instrument, and is particularly a kind of for ADCP(acoustic Doppler fluid velocity profile instrument) fish lead of river channel current surveying.
Background technology
The flow measurement of river waterflow flow is an important content of hydrlolgic work, traditional flow measurement adopts the mechanical propeller formula, is subject to easily pasture and water or with impact and the interference of the foreign material of water flow, causes measuring errors even instrument damage, and mechanical flow measurement stream field impact is large, and response efficiency is also lower.And ADCP(acoustic Doppler fluid velocity profile instrument) adopt Principles of Acoustics to carry out flow measurement, has higher precision and flow measurement efficient, the ADCP current surveying device generally is equipped with special-purpose trimaran, as shown in Figure 1, trimaran 1 has three hulls arranged side by side, steadily utilizing buoyancy of water to keep the stable of underwater penetration in the current, move by the traction of hawser.But it is too rapid to work as current, and trimaran rollover occurs easily causes the instrument water inlet; Work as strong wind weather, trimaran is subjected to wave effect, and the amplitude conference of rocking affects the flow measurement precision; When on the water surface drift being arranged during flow measurement, drift catches on trimaran and causes easily shipwreck.
Have at present and use fish lead to carry out flow measurement, CN1220035C patent such as Patent Office of the People's Republic of China's Granted publication on September 21st, 2005, name is called a kind of river flow measurer, this device uses the fish lead flow measurement, and the flow measurement sensor is installed above the fish lead head, utilizes the wire rope transfers sensor signal, because the fish lead underwater penetration is controlled by hawser, fish lead is not subject to the interference of pasture and water and foreign material in the water, and the weight of fish lead itself is large, good stability.But this device is applicable common flow measurement sensor only, with ADCP(acoustic Doppler fluid velocity profile instrument) to compare, the flow measurement precision is not enough to some extent, and existing fish lead can not be satisfied the flow measurement user demand of ADCP.
Summary of the invention
The purpose of this utility model is for ADCP flow measurement trimaran affected by environment large and existing fish lead is not suitable for the problem that the ADCP flow measurement uses, and a kind of fish lead of the ADCP of being applicable to flow measurement is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of fish lead of applicable ADCP flow measurement, comprise streamlined fish body small in the end and big in the middle, fish body top is provided with the suspention wirerope, the suspention wirerope is divided into the front and back end that two stocks do not connect the fish body by deconcentrator, the middle part of fish body is provided with vertical through hole, ADCP flow measurement probe is installed in the through hole, the fish body top of through hole front side or rear side is provided with signal bridge, signal bridge is provided with wireless signal transmission, and wireless signal transmission adopts signal wire to connect in ADCP flow measurement probe.Fish lead is by suspention wirerope control underwater penetration, and fish lead is in and partly enters water state during flow measurement, the bottom entry of ADCP flow measurement probe and top is positioned at more than the water surface, and the via bottoms degree of depth prevents that greater than the probe degree of depth foreign material damage probe in the current; Signal bridge is higher than the fish lead upper surface, guarantees that wireless signal transmission integral body is positioned at more than the water surface.Wireless signal transmission can adopt blue-tooth device.After the entry of fairshaped fish body downstream stream put on right position, be subjected to water currents little, even flow velocity is large, do not have the risk of being overturned yet; Fish body utilization suspention wirerope control height, and weight own is large, is subjected to wave effect little at strong wind weather; Because fish body Parallel to the flow direction, current are stopped little, be not subject to floating thing and impact, even there is larger floating thing to hook into the fish body, also can be by wirerope with the easily cleaning of leaving the water of fish body.
As preferably, the two sides of described fish body are labeled with for the waterline of observing fish body entry degree.The fish body is in the water surface movable process, and whether can submerge by the observation waterline reaches waterline under water apart from the height of the water surface, regulates suspention wirerope control fish body underwater penetration.
As preferably, described waterline comprises graticule and a row LED lamp concordant with graticule.Confirm underwater penetration by observing graticule when light condition is good, bad such as night when light condition, can turn on the LED lamp, be convenient to observe.
As preferably, the afterbody of described fish body is provided with flared tail fin.Adjust rapidly the position Parallel to the flow direction after can making the entry of fish body by tail fin.
As preferably, described fish body afterbody is provided with tail fin, is provided with the water level sensor that entry and water outlet can be sent unlike signal with highlands such as waterlines on the tail fin.When the weather condition is unfavorable for observing, can whether reach waterline position by the signal auxiliary judgment fish body underwater penetration of water level sensor.
As preferably, the tubular hole wall that the hole wall of described fish body through hole is integrated, two housings welding formed about the fish body case adopted, and two housings middle part double teams are outside the through hole hole wall.If the fish body adopts integrative-structure, because weight own is larger, fracture easily after the perforate of middle part, therefore adopt two housing butt welding, weld seam has strengthened the intensity of fish body along the longitudinal extension of fish body upper and lower surface.
As preferably, described fish body front/rear end is respectively equipped with the plumbous hole of filling of the plumbous liquid of perfusion in the fish body case.Can fill with plumbous hole from two and pour into plumbous liquid, make fish lead reach suitable weight, general fish lead weight specification has 100kg, 150kg, 200kg, 250kg, 300kg, 350kg, 400kg, 450kg, 500kg, also can use according to actual needs special requirement weight.
As preferably, be the detecting head of spherical crown surface bottom described ADCP flow measurement is popped one's head in, fish body via bottoms outwards launches to form the taper hole wall.The detecting head of spherical crown surface can have the scope of larger detection, and via bottoms is designed to the abduction taper, avoids detecting head formed stopping.
As preferably, also be provided with panel box between the signal bridge of described installation wireless signal transmission and the fish body upper surface, be provided with the power supply into each device power supply on the fish body in the panel box.Also can each install the powered battery that adopts respectively separately.
The utility model makes fish lead be applicable to the ADCP flow measurement by the redesign of fish lead structure; And by housing welding splicing structure, guarantee to have enough intensity after the fish lead structural modification; By various waterline view modes, guarantee operating personnel can be in time the as a result adjustment wirerope control fish lead underwater penetration of recruiting according to the observation.
