technical field

The utility model relates to a liquid level monitoring device, which belongs to the technical field of mine detection.

Background technique

In the leaching mining process of rare earth ore, it is essential to monitor the leaching liquid level in the leaching shaft. At present, most of them use the method of manual detection by operators, which is extremely inefficient and labor-intensive. Under the conditions of the leaching well site with hundreds or thousands of wellbores, it is often impossible to know the liquid level of each wellbore in real time, which leads to a decrease in leaching efficiency when the liquid level is low for a long time; when the liquid level is high for a long time, the leaching The liquid immerses into the upper covering rock and soil layer and causes the ineffective consumption of the leaching liquid.

Contents of the invention

The purpose of the utility model is to provide a liquid level monitoring device to solve the defects of high labor intensity and low leaching efficiency in the leaching mining process.

The support plate 12 of the device is fixed with a high slot photoelectric limit switch 6 and a low slot photoelectric limit switch 7 in the vertical direction, and the distance between the high slot photoelectric limit switch 6 and the low slot photoelectric limit switch 7 is Predetermined upper and lower limit water level difference. The surface of the upper cover of the device protection tube 13 is provided with an upper liquid level indicating luminous tube 10 and a lower liquid level indicating luminous tube 11. The photoelectric output pins of the switch 6 and the low slot photoelectric limit switch 7 are connected in series, and then connected in series with the power supply to form a loop. The upper surface of the high-position photoelectric limit switch 6 and the lower surface of the low-position photoelectric limit switch 7 are fixed with a high-level light-blocking element moving limiter 8 and a low-level light-blocking element moving limiter 9 . Both the moving limiting block 8 of the high-position light-blocking element and the moving limiting block 9 of the low-position light-blocking element are provided with small holes, and the pull wire 4 can pass through the small holes freely and vertically. The light blocking element 3 on the pull wire 4 is located between the upper slot photoelectric limit switch 6 and the lower slot photoelectric limit switch 7 .

The upper liquid level indicating luminous tube 10 and the lower liquid level indicating luminous tube 11 can adopt different colors for easy distinction.

When the device is working, the floating ball 1 is placed on the immersion liquid surface 15, and the light-emitting tubes of the high-position trough-type photoelectric limit switch 6 and the low-position trough-type photoelectric limit switch 7 in the immersion shaft 14 are in the state of constant light emission. When the liquid level of the liquid immersion surface 15 is within the set range, the light paths of the high-level groove photoelectric limit switch 6 and the low-level groove photoelectric limit switch 7 are not blocked by the light blocking element 3 therebetween, and the photoelectric output side string The connected upper liquid level indicator luminous tube 10 and the lower liquid level indicator luminous tube 11 are all in the lighted state; when the liquid level of the immersion liquid 15 is lower than the set range, the light blocking element 3 moves down with the floating ball 1, and the blocking element 3 Cut off the optical path of the low-level tank-type photoelectric limit switch 7, and the lower-level liquid level indicator light-emitting tube 11 goes out; The optical path of the high position groove type photoelectric limit switch 6, and the upper level liquid level indicates that the luminous tube 10 is extinguished.

By setting the light blocking element 3 on the upper and lower sides of the control range of the high-level slot-type photoelectric limit switch 6 and the low-level slot-type photoelectric limit switch 7 to move the limit block, it is also possible to make the high-level slot-type photoelectric limit switch when the liquid level is extremely dropped. 6. There is no barrier in the optical path of the low slot photoelectric limit switch 7, which causes misjudgment. the

The utility model has the following beneficial effects: the operator can obtain the liquid level of each wellbore in a large range by visually observing the light-emitting state of the light-emitting tube on the liquid level monitoring device of each wellbore at a place far away from each wellbore, thereby reducing his labor. strength.
