Abstract
The utility model relates to a traction apparatus of rope pull-type survey vessel, which comprises a survey vessel, a steel wire, pulleys hung on the upright posts at two banks of a river, a plurality of middle pulleys, an electric motor and a coiling block. One end of the steel wire is tied on the head of the survey vessel, is coiled into the coiling block through the middle pulleys as well as the pulleys and middle pulleys hung on the upright posts at the two banks of the river, and then is returned back and tied on the tail of the vessel; and the coiling block is driven by the electric motor. Compared with the prior art, the traction apparatus of rope pull-type survey vessel changes the prior mode of adopting manpower to drag and pull; when the vessel sails from one bank to the other bank, all the data needed to calculate the flux, including the river depth, stream speed and the horizontal position of the instrument in the river can be collected, thus improving the working efficiency; meanwhile, the speed of the survey vessel is easy to be controlled, then the collected data is more accurate. The traction apparatus of rope pull-type survey vessel has another advantage of being capable of surveying the flux of large-section drivers.
Description
Technical field:
The utility model relates to a kind of river discharge measurement technique, more specifically to a kind of draw gear that is used for the cable traction formula instrumentation ship of river discharge measurement.
Background technology:
In the prior art, traditional method for measuring river discharge comprises that artificial boat measurement, bridge are surveyed, cableway is measured and the measurement etc. of paddling, its groundwork is to lay many vertical lines on gaging section, sound the depth of the water at every vertical line place and measure a flow velocity to several points with current meter, thereby obtain mean velocity in vertical, and then obtaining cross-sectional area and mean velocity in section, flow is then obtained by the product of cross-sectional area and mean velocity in section.The measurement shortcoming of orthodox method is to need to measure the multiple spot calculating mean value, and not only labor content is big, and owes accurate.The appearance of acoustic Doppler current section plotter has been pushed ahead major step with surveying work in recent years.It is a physical principle of utilizing the hypracoustic Doppler frequency shift, can go back the energy measurement river degree of depth or river width simultaneously, thereby can directly calculate the section flow in river course with the very high resolution measurement vertical direction or the instantaneous velocity of horizontal direction current.When using acoustic Doppler current section plotter to measure the section flow at present, adopt the method that manually pulls instrumentation ship, efficient is not high, and can not solve the measurement of big section river discharge.For bringing into play the effect of acoustic Doppler current section plotter more fully, control its speed in current, make the data of its collection more accurate, increasing work efficiency still has a lot of problems anxious to be solved.
The utility model content:
The purpose of this utility model provides a kind of at the prior art weak point and is easy to control survey ship's speed degree, can measure big section river discharge, the draw gear of efficient height, time saving and energy saving cable traction formula instrumentation ship.
The purpose of this utility model is to realize by following measure: a kind of draw gear of cable traction formula instrumentation ship, comprise instrumentation ship, steel rope, its special character is to also have: be suspended on pulley, some intermediate pulley, electrical motor, reel on the column on bank, both sides, river; Described steel rope one end ties up to the instrumentation ship fore after intermediate pulley and be suspended on pulley, intermediate pulley on the column on bank, both sides, river and turn back after going into reel and tie up on the stern, and reel is by direct motor drive.
Described reel is that motor output shaft and reel rotating shaft are by a pair of belt pulley transferring power by direct motor drive.
Described reel is that the coupler transferring power is passed through in motor output shaft and reel rotating shaft by direct motor drive.
Compared with prior art, the draw gear of the cable traction formula instrumentation ship that employing the utility model proposes, changed and adopted the mode that manually pulls in the past, when ship navigates by water other shore from certain bank, can collect the required whole data of calculated flow rate, comprise the river degree of depth, water velocity and the instrument level attitude in the river, improve work efficiency, the speed of instrumentation ship is easy to control simultaneously, and the data that order is gathered are more accurate.Another advantage of the present utility model is to measure big section river discharge.
Description of drawings:
Fig. 1 is the utility model embodiment scheme drawing.
Fig. 2 is Fig. 1 embodiment power transmission scheme drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1 has provided the structural representation of the utility model embodiment.A kind of draw gear of cable traction formula instrumentation ship comprises: instrumentation ship 1, steel rope 2, be suspended on pulley 3, some intermediate pulley 6, electrical motor 4, reel 5 on the column on bank, both sides, river.Described steel rope one end ties up to the instrumentation ship fore after intermediate pulley and be suspended on pulley, intermediate pulley on the column on bank, both sides, river and turn back after going into reel and tie up on the stern, and reel is by direct motor drive.
Fig. 2 is Fig. 1 embodiment power transmission scheme drawing.Described reel by direct motor drive be motor output shaft and reel rotating shaft by a pair of belt pulley transferring power, motor output shaft is equipped with small pulley 41, drum shaft is equipped with big belt wheel 42.The transmission of motor power also can be that motor output shaft passes through coupler and directly links to each other with drum shaft.After electrical motor must power on instruction, drive reel and rotate, the folding and unfolding of reel drags instrumentation ship through steel rope and walks boat, and the acoustic Doppler current section plotter on the instrumentation ship is measured immediately, and the measured error of the low river discharge of row speed of a ship or plane degree is little.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
