The present invention relates to a groundwater measurement technology, and more particularly, in extending the casing to the deep heart of the basement, by improving the structure of the water level detector, the insertion depth of the casing, the groundwater level and the bottom of the ground (underground) The present invention relates to a water level detector and a groundwater measuring device using the same.

As is well known, groundwater has a low development cost compared to surface water and can produce a large amount of water in a small area unlike a reservoir, and has a low water pollution and a stable yield in a short period of construction.

In other words, the above ground water temperature is about 15 ℃, suitable for grassland composition water, such as field crops, ranch, etc., and especially suitable for raising cold fish species such as trout and heatfish, and these days, it is also widely used as industrial water. In order to correspond to the water level of the groundwater, casings with multiple inflow holes on the circumferential surface of the casing were installed to extend to the core.

However, the groundwater has a limited amount of storage, so if the pumping indefinitely, the water veins can not be pumped anymore, and the water can be reclaimed only after considerable time passes until the groundwater level is restored.

Therefore, in pumping groundwater, in order to pump only a certain amount of water before the vein dries, it is necessary to precisely detect the deep water level and thereby limit the amount of groundwater used.

In view of this point, conventionally, groundwater measuring devices have been developed and used in various ways. Among them, a portable groundwater measuring device has been disclosed. Among them, an alarm unit, which is not shown, is coated with polyester powder and emits sound and emits lamps. A rotating reel was configured on the measurement frame, and the rotary reel was wound with a wire having a scale mark, and a water level sensor was connected to one end of the wire.

In this case, the water level sensor is divided into an electrode rod connected to one end of the wire, a socket portion surrounding the electrode rod, and a plug portion coupled to the socket portion.

However, in the conventional groundwater measuring device, when water contact is made to the electrode of the level sensor, an electrical signal is transmitted to the alarm unit provided in the measurement frame through the wire, and accordingly, the alarm unit outputs an alarm sound and emits a lamp. Bar, while it is possible to detect the highest and lowest levels of groundwater according to the depth of insertion of the water level detector, the installation depth of the casing, as well as the detection of the bottom of the water was not effective.

That is, in a state where a certain level of groundwater exists in the casing, the conventional groundwater measuring device inserts a level sensor along the casing, and even though the plug part of the level sensor contacts the bottom, the electrode rod wrapped by the socket part is in the water. While it is located, it continuously transmits an electric signal to the alarm unit through the wire, so that the alarm sound output from the ground is not turned off. Therefore, the ground gauge does not determine whether the water level sensor has reached the bottom of the alarm unit. In the conventional measuring apparatus, the accuracy of the detection method for the deduction of the plug is deteriorated due to the discretion of the measurer. .

That is, when the level sensor is continuously submerged in water, the ground gauge determines the depth of the bottom from the scale mark of the electric wire that is released according to the dive. In the conventional measuring apparatus, even if the level sensor contacts the bottom, The wire connected to the water level detector has to be unrolled continuously to a certain range in the water. Accordingly, the ground gauge that measures the depth of deduction from the scale mark according to the unwinding of the wire, The measurement was inaccurate, such as inevitably calculating the depth of the co-operation, and it was inevitable that there were many cases.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the water level sensor to more accurately detect the insertion depth of the casing and the water level of the groundwater and the reach length from the ground to the bottom through the improvement of the structure of the water level detector And to provide a groundwater measuring device using the same is to have a purpose.
