Detailed Description

The present invention will be further explained with reference to the accompanying drawings and specific embodiments:

the utility model discloses a measuring staff 1, water level detection alarm 4, fishing line wheel 2 and meter number counter 6. The measuring rod 1 is provided with a fishing line wheel 2, a line clamping ring and a meter counter 6, and a fishing line 3 on the fishing line wheel 2 sequentially passes through the line clamping ring and a pulley of the meter counter 6 and is parallel to the measuring rod 1. The function of wire ring is to limit the fishing line 3 and make it joint with the measuring rod. The fishing line 3 drives the pulley to rotate, and the counter records the rotating circumference of the pulley and converts the circumference into corresponding meters.

The water level detection alarm 4 comprises a transparent shell, two copper probes 4.7 which are not in contact with each other are arranged at the bottom of the transparent shell, a battery 4.6, an LED lamp 4.2, an annular LED lamp 4.4, a circuit 4.5 and a buzzer 4.3 are arranged in the shell, a mercury film is coated on the outer wall of the buzzer 4.3 (used for reflecting light and increasing the brightness of the LED lamp), the two probes 4.7 are respectively connected with the positive electrode and the negative electrode of the battery 4.6 through a circuit, and the LED lamp 4.2, the annular LED lamp 4.4 and the buzzer are connected on the circuit after being connected in parallel. When the water level is measured, the two probes 4.7 contact the water surface to form a closed circuit, the buzzer 4.3 begins to buzz, and the LED lamp 4.2 and the annular LED lamp 4.4 begin to emit light. A hanging ring 4.1 is arranged above the transparent shell and is used for connecting the fishing line 3.

The fish lines 3 are arranged in black and white, and are equally distributed at intervals of 0.1 m. Taking the fish line outlet of the meter counter 6 as the initial position 7 of the measuring point, the initial section of the fish line must be a complete white section fish line or a black section fish line, taking the initial section as the white section for example, the white parts of the fish line are all odd decimeters, and the black parts are all even decimeters. The measurement accuracy of the meter counter 6 is 0.1m, and the part of the fishing line 3 not exceeding 0.1m cannot be measured, that is, the length of the fishing line less than 0.1m from the fishing line outlet of the meter counter 6 cannot be read from the meter counter 6. To this problem, the utility model discloses set up the scale 5 that the range is 0.1m, can be accurate to 0.001m on the measuring staff 1 of the fish tape import side of meter number counter 6, the zero scale of scale 5 is in the fish tape import department of meter number counter 6.

And the reading of the meter counting counter is a, the reading of the white section or black section of the fish line at the fish line inlet of the meter counting counter on the graduated scale is b, and the actual length of the fish line is a + b. The water level of the measured water body is obtained by subtracting a fixed value c (the value is the sum of the length of the water level detection alarm and the length of the fish line which passes through the meter number counter and is not read) from the actual length of the fish line. The measurement precision reaches 0.001 m. The length of the water level detection alarm is the distance from the probe to the top of the hanging ring. The length of the fish line which passes through the meter counter and is not read can be determined in advance, the meter counter is firstly adjusted to zero, the fish line passes through the meter counter, when the meter counter starts to read, the length of the part of the fish line which passes through the meter counter is measured, namely the length of the fish line which passes through the meter counter and is not read is obtained.

For example, when the water level of a well is measured, the reading of the meter counter is 3.2m, the reading of the non-whole scale (10cm) fish line part on the graduated scale is 0.051m, the actual length of the fish line is 3.251, the fixed value is 0.16m, and the fixed value is subtracted from the fish line length to obtain the water level buried depth of the measured water body to be 3.091 m.

In case a fixed value has been determined, such as a fixed value of 0.16m, the initial reading of the meter counter can be adjusted to-0.16 m, so that the actual length of the fish line is equal to the water level burial depth and no fixed value has to be subtracted.

As shown in figure 1, the meter counter is arranged at the right end of the measuring rod, and the graduated scale is arranged at the left side of the fish line inlet of the meter counter.

Detailed description of the devices employed in this example:

a buzzer: the 12V direct current is used for supplying power, 85-90 decibels can be achieved at a position of 0.1 meter, 45-50 decibels can be achieved at a position of 50 meters, the use environment is relatively closed and narrow due to the fact that the microphone is used in a drilling hole or a well, sound transmission is facilitated, and sound can be heard in time even if the microphone is used at a depth of 50 meters or more in the environment.

A battery: 4 button cells with one section of 3V, and the cell bin part adopts a waterproof design.

LED lamp: white light, 12V direct current power supply, if the water level is deep, the sound is small, and the light is observed to judge the water surface position (the drilling hole or the deep part in the well is generally dark and lightless).

The size specification is as follows: the whole body of the buzzer, the battery and the LED lamp is 4.5cm wide and 10cm long; a round bar with a measuring bar length of 0.5 m and a diameter of 2 cm; the meter counter is 6.6cm long, 5cm wide and 4cm high.

Fishing line: the black and white strong force hairtail lines are evenly distributed at intervals of 10cm, 9-knitted No. 1.0 can bear 10kg of tension. The material is high-strength polyethylene fiber, and because the high-strength polyethylene fiber is polymerized into one strand by adopting a plurality of high-strength fiber precursors, and then the weaving process is adopted for high-speed seamless tight interpenetration of 9 strands, so that the fishing line body is smooth and soft, the wear resistance is stronger, the tension is stronger, the surface is smooth, the water resistance can be reduced, and the fishing line body only needs 0.2 second after sinking into water and has no extension. Because of the characteristic of no extension, the buzzer main body can not cause larger pulling force to the fishing line, thereby ensuring the accuracy of measurement. The fishing line wheel can be installed with a semi-automatic fishing line wheel, and can automatically take up the fishing line after the measurement is finished.

A meter counter: the maximum meter number of the electronic money counter is 999.9 meters, the minimum meter number is 0.1 meter, and the length of the electronic money counter can be accurately measured no matter whether the fishing reel is on-line or pay-off or take-up. The rubber pad is arranged in the clamp, so that the rod body can be effectively protected when the rod is clamped, and the clamp is provided with the fixing screw, so that the rod body is prevented from falling off when in use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
