The groundwater level measuring apparatus and the water level measuring method using the watercage according to the embodiment of the present invention are characterized by simply removing the conventional method of measuring the water level by using a pressure sensor and applying the watercourse to the underwater floor of the groundwater, It is configured to accurately measure the level of the groundwater regardless of the atmospheric pressure which changes by the CCD camera.

Hereinafter, a groundwater level measuring apparatus and a water level measuring method according to an embodiment of the present invention will be described in detail.

Is an assembled perspective view for explaining the structure of the weight unit according to the example. And FIG. 5 is a block diagram for explaining components operating in a groundwater level measuring apparatus according to an embodiment of the present invention.

The groundwater level measuring apparatus according to the embodiment of the present invention includes a watercock 110, an elevating ring 120, a buoyant body 130, a CCD camera 140, a black box 150, A controller 170, a transceiver 180 and a weight unit 160. The scale 110 is extended to the bottom of the underground water W, The water level of the groundwater W can be measured by photographing the water level of the groundwater. Hereinafter, the configuration of the groundwater level measuring apparatus according to the embodiment of the present invention will be described in detail with reference to the above-described components.

First, the guide 110 is made of a flexible material so as to be easily released to the vessel T while being supported by the support device 111, and the lower end thereof is drained to the bottom of the groundwater. 3, a first sheet 110a and a second sheet 110b of a polyester fiber material, which are bonded to each other as shown in FIG. 3 and on which a scale for level measurement is printed, A plurality of sheets are inserted between the first sheet 110a and the second sheet 110b in a spaced manner to reinforce the strength of the first sheet 110a and the second sheet 110b, (110c). The aramid fiber which is the material of the reinforced yarn 110c is known to have an elongation of about 1 to 2%, and since it can fulfill a sufficient role even if it is provided in only a small amount compared with polyester which is generally used fiber, The first sheet 110a and the second sheet 110b in a ratio of about 1% to about 10%. On the other hand, in the case of the watercraft 110, as the water depth of the groundwater becomes deeper, it becomes unstable due to buoyancy, and is easily deformed by bending or the like, so that a weight unit 160,

The lifting ring 120 binds the buoyant body 130 and the CCD camera 140 so that the buoyant body 130 and the CCD camera 140 are positioned near the surface 110 of the groundwater. When the water level changes, the water level can be raised or lowered along the water course 110.

The buoyant body 130 floats the lifting ring 120, the CCD camera 140, and the black box 150 on the surface of the ground water. The buoyant body 130 is coupled to the lifting ring 120 and is located on the groundwater surface. The buoyant body 130 may be any eco-friendly material having a specific gravity lower than that of the groundwater and having no harmful effect, and may be made of a material such as styrofoam or synthetic resin.

The CCD camera 140 is installed on the upper surface of the buoyant body 130 to capture a scale of the watercraft 110 located near the surface of the groundwater and records the image of the watercraft 110 to the black box 150 under the control of the controller 170 And transmits it to the transceiver 180 so that it can be transmitted to the outside. An infrared LED 142 is provided near the lens 141 of the CCD camera 140 so that it can be photographed even in a dark hall T. [

The black box 150 serves to store image recordings taken by the CCD camera 140 and is installed in a form coupled with the CCD camera 140 on the upper surface of the buoyant body 130.

The controller 170 interlocks with and controls the CCD camera 140 and the infrared LED 142, the black box 150, and the transceiver 180 as shown in FIG.

The transceiver 180 is interlocked with the CCD camera 140 and the black box 150 so as to transmit an image record photographed by the CCD camera 140 to the outside of the housing T and receive a control signal transmitted from the outside And then sent to the controller 170. [ If the transceiver 180 transmits / receives a signal in a wireless manner, since the cable 151 drained as the gateway T is responsible for power supply and signal transmission, it is suitable to be connected to the transceiver 180, It is appropriate that the cable 151 is connected to the CCD camera 140 or the black box 150 rather than the transceiver 180 because the cable 151 is responsible for power supply when the transmitter 180 transmits and receives signals in a wireless manner.

Since the weight unit 160 is made of a flexible material, the watercraft 110 helps to reach the bottom of the water under the buoyancy while handling the buoyancy in the water. To this end, the weight unit 160 includes a support frame 161 having a pair of vertical portions, which are formed of a metal material as a whole and each have an upper surface-side guide groove 161a formed on an inner surface thereof facing each other, And a plurality of unit weights 162 which are inserted into the guide grooves 161a of the pair of vertical portions and stacked between the pair of vertical portions. A slit-shaped cutout 161b is formed on the front wall of the support frame 161 so that both end portions 162a of the unit weight 162 are inserted.

Particularly noteworthy in such a structure is that the weight unit 160 is formed in a form of stacking the unit weights 162 instead of a single mass. According to such a configuration, the weight of the unit weight 162 can be flexibly adjusted by adjusting the number of the unit weights 162 stacked so that the buckets 110 can maintain a smooth shape with respect to the buoyancy that increases as the water depth increases.

The method of measuring the groundwater level by the groundwater level measuring apparatus according to the embodiment of the present invention will now be described in detail with reference to the accompanying drawings. 6A to 6C are a series of reference views for explaining a groundwater level measurement method according to an embodiment of the present invention.

The weight unit 160 is suspended from the lower end of the guide 110 after the guide 110 passes through the inner diameter of the lifting ring 120 coupled with the buoyant body 130. The buoyant body 130, the CCD camera 140, and the black box 150 are bundled so that they can gather at the water surface of the ground through the lifting ring 120, The weight unit 110 can be deeply immersed in the groundwater by the weight of the weight unit 160. Then, as shown in FIG. 6A, the watercave 110 is supported in the supporting device 111, and is released into the tubular space T to be submerged in the groundwater W. At the same time, the buoyancy body 130, the CCD camera 140, the black box 150 and the like coupled to the lifting ring 120 are lowered to the surface of the groundwater W while releasing the cable 151.

6 (b), the watercage 110 is further drained into the groundwater W by the weight of the weight unit 160. In this case, as shown in FIG. However, due to buoyancy of the buoyant body 130, the lifting ring 120, the CCD camera 140, and the black box 150 remain floating on the water surface.

6C, the watercage 110 reaches the bottom of the water of the groundwater W by the weight of the weight unit 160. When the watercourse 110 reaches the bottom of the water of the groundwater W, The lifting ring 120, the CCD camera 140, and the black box 150 are still floated on the surface of the water due to buoyancy of the body 130. At this time, the water level can be measured by illuminating the surface of the groundwater (W) with the infrared LED 142 and taking a scale of the watercraft 110 corresponding to the water surface with the CCD camera 140. At this time, the image recorded by the CCD camera 140 is stored in the black box 150 and transmitted to the outside through the transceiver 180.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.

110: Screw 120: Lift ring
130: Buoyant body 140: CCD camera
150: Black box 160: Weight unit
