Abstract
The present application discloses a rod-type depth automatic measuring device comprising a telescopic rod body, the length of the telescopic rod body is capable of stretching, and the telescopic rod body is hollow, and provided with an opening on the bottom, the top of the telescopic rod body is provided with a positive and negative rotation motor, a motor shaft of the positive and negative rotation motor is transversely arranged, and stretches into a cavity of the telescopic rod body; the motor shaft located in the cavity of the telescopic rod body is winded with a tape measure, the free end bottom of the tape measure is connected fixedly with a counter weight; the tape measure is also provided with a tension sensor for detecting whether the tape measure is tensioned; the telescopic rod body is provided with a display screen, and the positive and negative rotation motor and the tension sensor are connected with the display screen. With the above structure, by arrangement of the tension sensor, whether the tape measure is tensioned can be detected, when the tape measure is in a relaxed state, the tension sensor sends the detect information to the positive and negative rotation motor, the positive and negative rotation motor may automatically perform reverse rotation, so that the tape measure is maintained in a tension state, then reading is performed, and the water depth reading is accurate, and high in reliability.
Description
Technical field
The application relates to a kind of technical field measured the river course depth of water, particularly a kind of rod-type degree of depth self-operated measuring unit.
Background technology
The depth of water is the important appearance features of one, water body, and in natural science field, its concept is very simple, also very directly perceived; Apply more in hydraulic engineering and shipping field at present.Water depth ratio can produce considerable influence, is the emphasis that people should consider, is also a difficult point simultaneously.
In hydraulic engineering, rod-type scale conventional at present also exists following deficiency:
1. easily tilt when scale is placed, easily cause the error of measurement.
2. length of the scale is fixed, and is difficult to the needs adapting to different water depth measure of the change.
3. during tape measure, be placed in water, reading is very inconvenient, and easily causes reading error.
4. utilize ultrasound wave, the sounder of electromagnetic wave etc. is expensive, carries inconvenience, is unfavorable for generally using.
Therefore, a kind of easy to carry, with low cost in the urgent need to inventing, convenient reading, can adapt to larger depth of water variation range, and the rod-type sounder that precision is higher.
application content
The technical matters that the application will solve is for above-mentioned the deficiencies in the prior art, and provides a kind of easy to carry, with low cost, and convenient reading, can adapt to larger depth of water variation range, and the rod-type degree of depth self-operated measuring unit that precision is higher.
For solving the problems of the technologies described above, the technical scheme that the application adopts is:
A kind of rod-type degree of depth self-operated measuring unit, comprise that a length can be stretched, hollow and the flexible body of rod of bottom opening, the top of this flexible body of rod is provided with a clockwise and anticlockwise motor, and the motor shaft horizontally set of this clockwise and anticlockwise motor also stretches in the cavity of the flexible body of rod; The motor shaft being positioned at flexible body of rod cavity is wound with tape measure, bottom the free end of tape measure, is fixedly connected with weight; Described tape measure is also provided with the tension pick-up that can detect tape measure whether tensioning; The described flexible body of rod is provided with display screen, and described clockwise and anticlockwise motor is all connected with display screen with tension pick-up.
The described flexible body of rod is also provided with view window.
Stretching by Electronic control of the described flexible body of rod.
After the application adopts said structure, there is following beneficial effect:
1. the setting of the above-mentioned flexible body of rod, can adapt to larger water depth ratio, and easy to carry.
2. tape measure is arranged in the hollow reservoir of the flexible body of rod, while playing fixation, to the depth survey of tape measure, can provide guide effect, prevent rod decline tape measure, causes measuring or reading error.
3. the setting of above-mentioned clockwise and anticlockwise motor and motor shaft, labour-saving simultaneously, can make automatically being elevated according to setting requirement of tape measure.
4. after weight contacts with river bed, tape measure, can along with the certain distance that automatically declines due to inertia, and tape measure will be in relaxed state, and at this moment, if directly read depth of water reading, then reading result and actual gap are comparatively large, read untrue.The setting of mentioned strain sensor, tape measure whether tensioning can be detected, when tape measure is in relaxed state, Detection Information is passed to clockwise and anticlockwise motor by tension pick-up, clockwise and anticlockwise motor will rotate backward automatically, makes tape measure keep tensioning state, at this moment, carry out reading again, then depth of water accuracy of reading, fiduciary level are high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of rod-type degree of depth of the application self-operated measuring unit.
Wherein have: 1. the flexible body of rod; 2. tape measure; 3. clockwise and anticlockwise motor; 4. motor shaft; 5. weight; 6. tension pick-up; 7. display screen.
Embodiment
Below in conjunction with accompanying drawing and concrete better embodiment, the application is described in further detail.
As shown in Figure 1, a kind of rod-type degree of depth self-operated measuring unit, comprise that a length can be stretched, hollow and the flexible body of rod 1 of bottom opening, the top of this flexible body of rod 1 is provided with a clockwise and anticlockwise motor 3, and the motor shaft horizontally set of this clockwise and anticlockwise motor 3 also stretches in the cavity of the flexible body of rod 1; The motor shaft 4 being positioned at the flexible body of rod 1 cavity is wound with tape measure 2, bottom the free end of tape measure 2, is fixedly connected with weight 5; Described tape measure 2 is also provided with the tension pick-up 6 that can detect tape measure whether tensioning; The described flexible body of rod 1 is provided with display screen 7, and described clockwise and anticlockwise motor 3 is all connected with display screen 7 with tension pick-up 6, and display screen 7 is built-in with PLC.
After weight 5 contacts with river bed, tape measure 2, can along with the certain distance that automatically declines due to inertia, and tape measure 2 will be in relaxed state, and at this moment, if directly read depth of water reading, then reading result and actual gap are comparatively large, read untrue.
The setting of mentioned strain sensor 6, tape measure 2 whether tensioning can be detected, when tape measure 2 is in relaxed state, Detection Information is passed to the PLC in display screen 7 by tension pick-up, instruction clockwise and anticlockwise motor 3 rotates backward by PLC automatically, makes tape measure 2 keep tensioning state, at this moment, carry out reading again, then depth of water accuracy of reading, fiduciary level are high.
Further, the above-mentioned flexible body of rod 1 is also provided with view window.
Further, the above-mentioned flexible body of rod 1 is flexible by Electronic control.
