Abstract
The invention belongs to the technical field of waterpower electric power, and particularly relates to a speed measuring device for water flow under ice. The speed measuring device for the water flow under the ice comprises rulers, a flow meter and a reading gage. A through hole is formed in a base, a sealed type ruler sleeve pipe penetrates in the through hole and is bonded, and the sealed type ruler sleeve pipe is fixedly connected with a ruler reading window and a first ruler. A second ruler and a signal cable are arranged in the sealed type ruler sleeve pipe in a penetrating mode, the second ruler is connected with a mechanical gear inside a ruler knob in a meshed mode, so that the second ruler can move up and down along with the rotation of the ruler knob. Flexible sealing materials are arranged on the bottom of the sealed type ruble sleeve pipe. A flow meter protection baffle and the flow meter are connected with the lower end of the second ruler, and the flow meter is connected with the lower end of a signal cable penetrating out of the sealed type ruler sleeve pipe. The speed measuring device for the water flow under the ice has the advantages of being simple in structure, convenient to operate and use, and wide in applicability. The underwater depth of the flow meter can be adjusted in measurement, the flow meter does not need to be taken back after being mounted under water, continuous reading can be carried out directly, time and labor are saved, and the working efficiency and the accuracy of measuring data are improved obviously.
Description
Technical field
The invention belongs to the hydraulic power technical field, relate in particular to a kind of subglacial water Flow Velocity measurement mechanism.
Background technology
Measure flow rate of water flow under ice sheet during winter, the conventional way is: regularly on the ice face, hole, artificial portable current meter is placed under water to be measured, after having measured at every turn again by artificial taking-up current meter.
There is certain defect in this flood control way in the past:
(1) degree of depth under water of current meter is not easy accurate grasp;
(2) the each measurement all wanted artificial hand-held current meter, current meter proposed after completing measurement again, during the next time measurement, again puts into water, cumbersome, and should not operate;
(3) flow velocity of measuring is the instantaneous value of each manual measurement, there is no continuous change in flow process values, so there is the problem of accuracy in measurement result.
Summary of the invention
For above-mentioned problems of the prior art, the invention provides a kind of subglacial water Flow Velocity measurement mechanism.Purpose is to provide a kind of simple in structure, easy to use, and the accuracy of measuring a kind of subglacial water Flow Velocity measurement mechanism that can be significantly improved.
The present invention is achieved through the following technical solutions:
Subglacial water Flow Velocity measurement mechanism, comprise scale, current meter and readout instrument, is to be provided with through hole on base, and closed scale sleeve pipe penetrates in hole and bonds, and be connected and fixed with rod reading window and scale one; Scale two and signal cable are penetrated in closed scale sleeve pipe, and scale two is connected with the mechanical gear of scale knob inside, and scale two can be moved up and down with the rotation of scale knob; Bottom at closed scale sleeve pipe is provided with flexible sealing material; The lower end of scale two connects current meter protection baffle plate and current meter, and current meter is connected with the lower end of the signal cable passed from closed scale sleeve pipe.
The upper end of described signal cable connects readout instrument.
Advantage of the present invention and beneficial effect are:
(1) structural design is simple, easy for operation, and usability is extensive;
(2) while carrying out surveying work, the underwater degree of depth of current meter can be regulated, and direct reading;
(3) after current meter is arranged under water, needn't fetch, while again measuring, direct reading gets final product, and saves the course of work of artificial placement and taking-up, and the working time is shortened greatly, and has saved manpower, and work efficiency is significantly improved;
(4) readout instrument can continuous recording subglacial water Flow Velocity, and the accuracy of measurement data has obtained significant raising.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: closed scale sleeve pipe 1, rod reading window 2, scale knob 3, scale 1, scale 25, signal cable 6, base 7, current meter protection baffle plate 8, current meter 9, ice face 10, readout instrument 11, flexible sealing material 12.
Embodiment
The present invention is a kind of subglacial water Flow Velocity measurement mechanism, and this device can be measured water velocity under ice sheet, the flow rate measuring device base is positioned on ice face 10, and after signal cable connects readout instrument, can continuous coverage subglacial water Flow Velocity.
Subglacial water Flow Velocity measurement mechanism of the present invention consists of the following components: closed scale sleeve pipe 1, rod reading window 2, scale knob 3, scale 1, scale 25, signal cable 6, the wooden base 7 of flow rate measuring device, current meter protection baffle plate 8, current meter 9.
Connected mode: wooden base 7 centre-drilling holes of flow rate measuring device penetrate closed scale sleeve pipe 1 in hole and bond, and are connected and fixed with rod reading window 2 and scale 1.Scale 25 and signal cable 6 are penetrated in closed scale sleeve pipe 1, and scale 25 is connected with the mechanical gear of scale knob 3 inside, and scale 25 can be moved up and down with the rotation of scale knob 3.Be provided with flexible sealing material 12 in the bottom of closed scale sleeve pipe 1.
Lower end welding current meter protection baffle plate 8 and the current meter 9 of scale 25, current meter 9 is connected with the lower end of the signal cable 6 passed from closed scale sleeve pipe 1.
Using method: after the water surface is freeze-up, manually at ice face 10, dig out a duck eye, current meter 9 is put into to hole, the wooden base 7 of flow rate measuring device is placed on ice face 10 to be fixed.Rotation scale knob 3, be adjusted to by current meter 9 fathoming of needing.Again the upper end of signal cable 6 is connected to readout instrument 11, this readout instrument 11 can directly be purchased the finished product readout instrument supporting with current meter, records current meter 9 flow velocity signals.
