Description
Technical Field
The utility model relates to a portable rivers velocity of flow survey device. The method is suitable for the fields of geological mapping, geological survey and engineering survey.
Background
At present, during geological mapping, geological survey and engineering survey, streams, ditches and spring water are often encountered, and the flow rate of the water flow needs to be measured. Because the traditional triangular weir has large volume, heavy weight and is inconvenient to carry, geologists generally adopt a simple test method, namely, paper sheets or tree (grass) leaves and the like are used as floaters to measure the flow velocity on site, and then the area of the water flow section is estimated, so that the flow is calculated. The method has the advantages that the floater is not striking, the influence on the shape of the floater is large, the drift distance is difficult to measure, and the like, so that the influence on the measurement of the water flow velocity is large, and how to simply, conveniently and accurately measure the water flow velocity in a field environment is the key point and the difficulty of the current velocity measurement equipment.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: aiming at the problems, the portable water flow velocity measuring device has the advantages of simple structure, convenient manufacture and lower cost.
The utility model adopts the technical proposal that: a portable water flow velocity measuring device is characterized in that: the floating ball is connected with the fixed end through a connecting line with a certain length.
The surface of the floating ball is provided with a circle of groove capable of winding the connecting wire.
The fixed end is a pull ring which can be fixed on the hand of a tester.
The fixing device is provided with a tension sensor connected with the connecting wire, the tension sensor is connected with the controller through a circuit, and the controller is connected with a timing starting switch and a timer through a circuit;
the controller controls the timer to start timing after receiving a starting signal of the timing starting switch; and the controller controls the timer to stop timing after receiving the tension data acquired by the tension sensor.
The utility model has the advantages that: the utility model discloses connecting wire length between well floater and the stiff end is certain, can calculate the velocity of flow of rivers according to the time that the connecting wire was straightened, simple structure, convenient operation. The utility model discloses in there being the round recess on floater surface system, the connecting wire can twine on the recess on floater surface, accomodates the convenience, portable.
Drawings
Fig. 1 is a schematic structural diagram of the embodiment.
FIG. 2 is a circuit schematic of an embodiment.
Detailed Description
Example 1: as shown in fig. 1, the present embodiment is a portable water flow velocity measuring device, which includes a floating ball 1, a connecting wire 2 and a pull ring 3 as a fixed end, wherein the connecting wire 2 has a fixed length of 2m, 3m or 4m, one end of the connecting wire 2 is connected to the floating ball 1, and the other end of the connecting wire 2 is connected to the pull ring 3.
In the embodiment, the diameter of the floating ball 1 is 5 cm-10 cm, the groove 101 is formed along the large circular line of the surface, the cavity is formed inside, the weight is light, and the floating ball can float on the water surface. The connecting point of the connecting line 2 and the floating ball 1 is positioned in the groove 101, and the connecting line 2 can be wound in the groove 101 on the surface of the floating ball when the floating ball is carried.
The method of use of this example is as follows: tester face down stream is fixed in on self finger with pull ring 3, holds the floater and presses close to the surface of water, releases floater 1, begins the timing with stopwatch or other equipment simultaneously, and the floater drifts along with the water, in case the floater drifts to connecting wire 2 when becoming the straight line, stops the timing, and connecting wire length divides to drift time and is the velocity of flow.
Example 2: the embodiment is substantially the same as embodiment 1, except that a tension sensor 5, a controller 4, a timer 6 and a timing start switch 7 are arranged in the pull ring 3, the tension sensor 5 is connected with a connecting wire to collect the tension of the connecting wire, the tension sensor 5 is electrically connected with the controller 4, and the timer 6 and the timing start switch 7 are electrically connected with the controller 4 (see fig. 2).
The method of use of this example is as follows: tester face down, on being fixed in self finger with pull ring 3, hold the floater and press close to the surface of water, relieve floater 1, press timing start switch 7 simultaneously, controller 4 receives control timer behind timing start switch 7's the signal and begins the timing, floater 1 drifts with the water, in case the floater drifts to connecting wire 2 when becoming straight line, the connecting wire gives force transmission for force sensor 5, force sensor 5 transmits when the pulling force numerical value of controller 4 is not 0 (when the connecting wire does not become straight line, the pulling force that force sensor 5 gathered is 0), controller 4 control timer stops the timing, connecting wire length divides to drift time and is the velocity of flow for the rivers.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
