Abstract
The utility model discloses a river channel current surveying device. The current surveying device comprises a cableway chamber (1), a current meter (2), a switch (3), an underwater polar plate (4), and conducting wires (5), and is characterized in that a pointer type multimeter (6) is mounted in the cableway chamber (1), the positive pole of the pointer type multimeter (6) is connected with the switch (3) and the current meter (2) through conducting wires (5), the negative pole of the pointer type multimeter (6) is connected with the underwater polar plate (4) through conducting wires (5), and a water conductor is arranged between the current meter (2) and the underwater polar plate (4). The current surveying device has the advantages of simple structure, convenient operation, and high sensitivity, and can ensure timeliness and accuracy of data.
Description
Technical field
The utility model relates to measurement mechanism, is specifically related to river course flow measurement device.
Background technology
The discharge of river is the important component part of hydrologic data, and is especially interim when flood season, needs in time to measure the discharge of river.Traditional flow measurement is adopted and is built the cableway room on the limit, river course, and spacing is placed on current meter and pole plate under water in the river course by lead and sound equipment formula signal receiver in the water conductor is connected the cableway room, forms electric loop.During flow measurement, current meter rotates the switch that drives above it and makes on-off action, receives the make-and-break signal of pronunciation formula at signal receiving end; Signal receiving end resistance should be infinitely great when switch above the current meter disconnects, signal receiving end resistance should be the resistance-water resistance of water conductor when switch connection, it is not obvious at signal receiving end when water resistance is bigger than normal with the signal that sound equipment formula signal receiver receives, perhaps just do not have signal at all, people can't write down current meter number of revolutions within a certain period of time, also promptly can't calculate flow.
Summary of the invention
The purpose of this utility model is: a kind of river course flow measurement device is provided, and this flow measurement device sensitivity height is convenient for measuring personnel's signal acquisition, the timely and effective streamflow data that obtains.
Technical solution of the present utility model is: this flow measurement device includes cableway room, current meter, switch, pole plate and lead under water, it is characterized in that: in the cableway room, pointer multimeter is installed, the positive pole of pointer multimeter connects switch and current meter by lead, the negative pole of pointer multimeter connects pole plate under water by lead, current meter and be the water conductor under water between the pole plate.
In the river course of the present utility model flow measurement device, pole plate is one group of series connection of pole plate under water under water.
During flow measurement, pointer multimeter is beaten on the resistance gear, current meter rotates the switch that drives above it and makes on-off action, and it is exactly that pointer is beated regularly that make-and-break signal is reflected on the pointer multimeter, and survey crew is caught the pointer number within a certain period of time and is converted into flow.
Of the present utility model simple in structure, easy to operate, highly sensitive, the property promptly and accurately of assurance data.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: cableway room 1,2 current meters, 3 switches, 4 pole plates under water, 5 leads, 6 pointer multimeters.
Embodiment
As shown in Figure 1, this flow measurement device includes cableway room 1, current meter 2, switch 3, pole plate 4 and lead 5 under water, it is characterized in that: pointer multimeter 6 is installed in cableway room 1, the positive pole of pointer multimeter 6 connects switch 3 and current meter 2 by lead 5, the negative pole of pointer multimeter 6 connects pole plate 4 under water by lead 5, current meter 2 and be the water conductor under water between the pole plate 4.
In the river course of the present utility model flow measurement device, pole plate 4 is one group of series connection of pole plate under water under water, and pole plate is laid to opposite bank, riverbed direction as far as possible under water, reduces the resistance enhancing signal to reduce the distance.
During flow measurement, with 6 dozens of pointer multimeters on the resistance gear, current meter 2 rotates the switch 3 that drives above it and makes on-off action, and it is exactly that pointer is beated regularly that make-and-break signal is reflected on the pointer multimeter 6, and survey crew is caught the pointer number within a certain period of time and is converted into flow.
Claims (2)
