Detailed Description

The present invention will be described in further detail with reference to the following examples:

a depth recording device for hydrological measurement is shown in figures 1-3 and comprises a metering wheel 2 and a photoelectric coded disc 1 which are fixedly arranged on a box body 3, wherein the metering wheel 2 and the photoelectric coded disc 1 rotate coaxially, the photoelectric coded disc 1 is electrically connected with a control display module 5 through a lead 4, and the box body 3 is arranged to effectively fix the metering wheel 2 and the photoelectric coded disc 1 and ensure that the metering wheel 2 and the photoelectric coded disc 1 rotate coaxially.

The photoelectric code disc is one kind of digital sensor, and converts displacement into electric signal in digital code form through photoelectric conversion for output in digital code form. The code disc is used for measuring angle (or angular displacement), the code scale is used for measuring length (or linear displacement), and the code disc and the code scale are collectively called as an encoder. When a light source forms a long and narrow light beam through a large-aperture aspheric condenser lens to irradiate a code wheel, a photoelectric device positioned behind a slit and an output signal are determined by the rotation angle position of the code wheel; the output signal is amplified, amplitude-discriminated (detecting '0' or '1' level), shaped, added with error correction and register circuit if necessary, then converted by equivalent weight, finally decoded and displayed on the control display module 5, that is, the linear displacement for length measurement is displayed on the control display module 5.

The metering wheel 2 and the photoelectric coded disc 1 rotate coaxially, namely the metering wheel 2 rotates for a circle, the photoelectric coded disc 1 also rotates for a circle, the number of codes recorded by the rotation of the photoelectric coded disc 1 for a circle is fixed, the circumference of the rotation of the metering wheel 2 for a circle is also determined, the number of codes recorded by the rotation of the photoelectric coded disc 1 for a circle corresponds to the circumference of the rotation of the metering wheel 2 for a circle one by one, the circumference of the rotation of the metering wheel 2 for a circle is also the linear displacement of the measuring rope 10 penetrating through the metering wheel 2, and the circumference value of the metering wheel 2 (or the linear displacement of the measuring rope 10 penetrating through the metering wheel 2) corresponding to the number of codes recorded by the rotation of the photoelectric coded disc 1 is set to be displayed on the control display module 5. In the same way, the code number recorded by the rotation of the photoelectric coded disc 1 corresponds to the linear displacement of the measuring rope 10 passing through the metering wheel 2 one by one.

As shown in figure 2, the line outlet end of the line 10 which crosses the metering wheel 2 is placed in the borehole and the line outlet end of the line 10 moves downwardly in the borehole by a distance corresponding to the linear displacement of the line 10 over the metering wheel 2, i.e. when the line outlet end of the line 10 reaches the target layer of the borehole, the linear displacement of the line 10 across the metering wheel 2 is the length of the line 10 across the metering wheel 2, i.e. the depth of the target layer of the borehole. As the linear displacement passing through the metering wheel 2 is in one-to-one correspondence with the code number recorded by the rotation of the photoelectric code disc 1, the depth of the target layer of the well hole is accurately displayed on the control display module 5 in real time. Therefore, the depth of the target layer of the well hole is visually displayed on the control display module 5, the measuring rope 10 is not required to be marked, the accurate measurement of the depth of the target layer of the well hole can be completed without manual recording, errors caused by manual measurement are avoided, and the method is stable, reliable, firm, durable, high in measurement accuracy and necessary to popularize.

As shown in figure 1, threading holes 6 are symmetrically formed in the bottom of the box body 3, and the wire inlet end and the wire outlet end of the measuring rope 10 are connected with the metering wheel 2 through the threading holes 6. The arrangement of the threading hole 6 is convenient for the wire inlet and outlet of the measuring rope 10.

The interior symmetry of box 3 is equipped with leading wheel 9, leading wheel 9 symmetry sets up the below at metering wheel 2, and survey rope 10 through wires hole 6 all is connected with metering wheel 2 through leading wheel 9. The guide wheel 9 is convenient for guiding the measuring rope 10, and the deviation of the measuring rope 10 can be effectively prevented.

As shown in fig. 3, the measuring rope 10 is a two-core cable, the measuring rope 10 is wound on a rotating shaft, the rotating shaft is arranged between the wire inlet end of the measuring rope 10 and the wire inlet hole 6, when the measuring rope 10 is lowered, the wire outlet end of the measuring rope 10 is slowly lowered to the drill hole, and simultaneously the rotating shaft rotates to slowly separate the measuring rope 10 wound on the rotating shaft from the rotating shaft and feed the measuring rope into the drill hole.

In the process of transferring, the inlet wire end of measuring rope 10 is connected with "+", "-" of universal meter 11 respectively, and the outlet wire end of measuring rope 10 is connected in touching water probe 12 respectively, touch water probe 12 and be the conductor of tip exposed surface winding insulating layer, ensure that the end of the in-process of transferring touches water probe 12 can not bump the contact, and at this moment, the resistance that universal meter 11 shows is infinity, and when touching water probe 12 and transferring its tip and drilling water level 13 contact, universal meter 11 shows that resistance is very little. Because water is a conductor, when the water contact probe 12 contacts the drilling water level 13, a conductive loop is formed among the universal meter 11, the measuring rope 10, the water contact probe 12 and the drilling water level 13, and the numerical value displayed on the control display module 5 is the depth value of the drilling hole.

In order to accurately measure the depth of a target layer of a well hole, the box body 3 is fixedly arranged on the platform 7, and the platform 7 can prevent the box body 3 from shaking and moving in the working process to cause inaccuracy of code number recording of the photoelectric coded disc 1, so that the depth measuring error of the target layer of the well hole is caused.

The lower part of the platform 7 is provided with an integral device fixing leg 8, the integral device fixing leg 8 can effectively support and fix the platform 7, and the platform 7 is ensured to be in a stable state. Therefore, the device needs to be fixed near the well hole when in operation.
