Conventionally, in order to collect water, a worker has to manually sample a sample. In this process, there is a possibility that a sample sampled due to a worker's mistake may be contaminated or altered.

In order to solve such problems, a water taking device including a watering module located in the water and a watering device connected to the watering hose by a hose and sucking water in the watering module is developed.

However, in the conventional water taking apparatus, there is a problem that foreign substances are caught on the valve formed in the hose connecting the water taking module and the water sampler, so that the collected sample is leaked out. In addition, in the conventional water supply apparatus, there is an inconvenience that the operator must directly move the water supply apparatus to the corresponding point.

Therefore, even if a valve is not formed, water does not flow out from inside, and a demand is made for a watering device which is easy to move.

At this time, the housing part 20 may be coupled with a buffer member 230 for absorbing an impact when the housing part 20 is coupled with the coupling part 10 on the upper surface. The buffer member 230 varies in response to an external force and can absorb shock. That is, the buffer member 230 may be formed to have elasticity.

The motor unit 30 and the rope unit 40 are components for adjusting the separation distance between the coupling unit 10 and the housing unit 20. [ The motor unit 30 is located in the inner space 200 and the winch 300 to which the rope unit 40 is wound can be coupled to the rotating shaft. One end of the rope portion 40 may be wound around the winch 300 and the other end may be coupled to the engaging portion 10. The distance between the engaging portion 10 and the housing portion 20 can be adjusted as the rope portion 40 is wound or unwound by the winch 300 as the motor portion 30 rotates.

On the other hand, the rope portion 40 can be coupled with the tension holding member 400. The tension holding member 400 can uniformly adjust and maintain the tension of the rope portion 40 while winding or drawing the rope portion 40. [ Even if the receiving portion 50 moves suddenly due to the flow of water due to the formation of the tension holding member 400, no shock is applied to the drones. On the contrary, even if the drones move up and down during the fly, It is possible to maintain a constant position.

The accommodating portion 50 is a component for storing sucked water. The accommodating portion 50 may have a receiving space 500 for accommodating the fluid therein, and may be detachably coupled to the housing portion 20.

Further, the accommodating portion 50 may be detachably coupled with the float 540 that provides buoyancy to the outer circumferential surface. Therefore, the accommodating portion 50 of the present invention does not fall into the water even in the flow of water, and can keep the floating state on the water surface and can collect the water.

Referring to FIG. 6, according to an embodiment of the present invention, the accommodating portion 50 may further include a suction port (not shown) for sucking water located on the outside of the accommodating portion 50, An outlet (not shown) for discharging water located in the accommodation space 500 may be formed on the bottom surface. At this time, the suction port 510 may be coupled to the suction port, and the external water may be sucked into the receiving space 500 through the suction pipe 510. At this time, the suction pipe 510 may be inserted and coupled to a predetermined position of the accommodation space 500. Accordingly, the water located below the one end of the suction pipe 510 located in the accommodation space 500 may not flow out to the outside.

An opening / closing member 520 for opening / closing the discharge port may be formed at the discharge port, and the opening / closing member 520 may be a cap or a valve. Thus, the user can easily discharge the water located in the accommodation space 500 to the outside. Although the present invention has been described with reference to the case where the opening and closing member 520 is formed as a rotating stopper, the outlet port is formed on the lower surface of the accommodating portion 50, but the present invention is not limited thereto.

The pump unit 60 is a component that sucks fluid in the accommodation space 500. The pump unit 60 may include a suction port 600 for sucking fluid and a discharge port 610 for discharging fluid on one surface thereof. A conveyance pipe (not shown) communicating with the accommodation space 500 may be coupled.

That is, during operation of the pump unit 60, the fluid in the accommodation space 500 moves to the pump unit 60 along the transfer pipe, so that negative pressure can be formed, As shown in Fig. Meanwhile, the receiving portion 50 may have a coupling hole 550 to which a transfer tube is coupled.

5, a plurality of first fastening blocks 210 may be formed on the inner circumferential surface of the housing part 20 for coupling the housing part 20 and the accommodating part 50, The receptacle 50 may have a second fastening block 530 formed on the upper surface thereof with a fastening protrusion that is inserted into the fastening block at a position corresponding to the first fastening block 210. The user inserts the second fastening block 530 into the inner space and then rotates so that the engaging projection of the second fastening block 530 is inserted into the engaging groove of the first fastening block 210 to be inserted into the housing portion 20 The receiving portion 50 can be coupled.

According to an embodiment of the present invention, the first fastening block 210 and the second fastening block 530 are formed with through holes communicating with each other when the first fastening block 210 and the second fastening block 530 are fastened And the through holes 240 may be inserted into the through holes 211 and 531. [

When the user desires to release the fastening of the first fastening block 210 and the second fastening block 530, the user removes the through pin 240 inserted in the through holes 211 and 531, The engagement of the fastening block 210 and the second fastening block 530 can be released. That is, the housing part 20 and the housing part 50 are more firmly coupled and are not easily separated by the external environment during movement through the drones.

The control unit 70 is a component for controlling the driving of the motor unit 30 and the pump unit 60. The control unit 70 will be described in detail below with reference to Fig.

 4 and 7, the water taking apparatus 1 may further include at least one of an encoder 310, a pressure sensor 220, a tension measuring sensor 410, and a water level sensor 330, These may be connected to the control unit 70 by wire or wirelessly.

The encoder 310 is a component for measuring the number of revolutions of the winch 300 and can be coupled to the winch 300 and can transmit the measured number of revolutions to the control unit 70. At this time, a rotary encoder capable of measuring the number of revolutions of the encoder 310 may be used. Of course, in addition to the rotary encoder, various types of encoders that can accurately measure the number of revolutions of the winch 300 may be used.

The pressure sensor 220 is a component that senses the presence or absence of a pressure applied to the upper surface of the housing part 20 and can be coupled to the housing part 20. [ The pressure sensor 220 may transmit a pressure sensing signal to the controller 70 when pressure is sensed.

The tension measuring sensor 410 is a component for measuring the tension of the rope portion 40 and may be coupled to the rope portion 40 and may transmit the measured tension value to the control portion 70. [

The water level sensor 330 is a component sensing the level of water located in the receiving space 500 and may be coupled to the inner circumferential surface of the receiving part 50. The water level detection sensor 330 is installed to detect water of a specific height and can transmit a water detection signal to the controller 70 when water is detected.

The control unit 70 is connected to the encoder 310, the pressure sensor 220, the tension measuring sensor 410 and the water level sensor 330 in a wired or wireless manner, And controls the driving of the pump unit 60. [

The control unit 70 may control the driving of the motor unit 30 so that the rope unit 40 is released by a predetermined length based on the rotation number received from the encoder 310. [

More specifically, when the number of revolutions received is less than a predetermined number of revolutions or exceeds a predetermined number of revolutions, the control unit 70 can drive the motor unit 30. If the number of revolutions received is a predetermined number of revolutions, The driving of the motor unit 30 can be stopped.

The control unit 70 can determine whether the coupling unit 10 is coupled to the housing unit 20 by receiving the press detection signal from the pressing sensor 220. The control unit 70 can determine whether the coupling unit 10 is coupled to the housing unit 20 20 of the motor unit 30 according to whether the motor unit 30 is coupled to the motor unit 30 or not. That is, when the pressure sensing signal is received, the control unit 70 determines that the coupling unit 10 is coupled to the housing unit 20, stops the driving of the motor unit 30, It is determined that the coupling portion 10 is not coupled to the housing portion 20 and the motor portion 30 can be driven.

The control unit 70 may determine whether the receiving unit 50 is seated on the water surface based on the tension value received from the tension measuring sensor 410. If the receiving unit 50 is seated on the water surface, The driving of the unit 30 can be controlled.

More specifically, when the received tension value is equal to or greater than a preset tension value, the controller 70 determines that the receiving portion 50 is not seated on the water surface, and the motor portion 30 When the received tension value is less than the predetermined tension value, it is determined that the storage portion 50 is seated on the water surface, and the drive of the motor portion 30 is stopped so that the rope portion 40 is no longer drawn out You can stop. When the received tension value is less than a preset tension value, the controller 70 drives the pump unit 60 to allow water to be sucked into the accommodation space 500.

Finally, the control unit 70 can determine whether the water is filled up to a specific height in the accommodation space by receiving the water sensing signal received from the water level sensor 330, thereby controlling the driving of the pump unit 60 .

That is, when the control unit 70 receives the detection signal, it can determine that the water is filled up to a certain height, stop the driving of the pump unit 60 so that the water is no longer sucked into the accommodation space 500, When the detection signal is not received, it is determined that the water is not filled up to a certain height, and the pump unit 60 can be driven so that the outside water is sucked into the accommodation space 500.

In other words, according to the present invention, when an appropriate amount of water is sucked into the accommodation space, the driving of the pump portion 60 is stopped, so that water exceeding the volume of the accommodation space 500 is not sucked into the accommodation space side, It is possible to prevent troubles caused by water overflowing to the part (60). When the water sensing signal is received, the control unit 70 drives the motor unit 30 so that the rope unit 40 is wound on the winch 300, so that the housing unit 20 moves toward the engaging part 10 side .

On the other hand, the water taking apparatus 1 is provided with a battery 80 for supplying electric power to the motor unit 30, the pump unit 60 and the control unit 70 for driving the water taking apparatus, And can be powered from the drones.

3 is a view showing a state in which water taking apparatus 1 according to an embodiment of the present invention collects water.

As described above, in the water taking apparatus 1 of the present invention, only the housing portion 20 and the accommodating portion 50 are moved to the water surface side while maintaining the distance between the engaging portion 10 coupled to the drone and the water surface, . Thus, the present invention can prevent the drones from being damaged by the sudden flow of water. Further, in the water taking apparatus 1 of the present invention, all the components operated by electric power are located inside the housing portion 20 and are spaced apart from the accommodating portion 50, so that the occurrence rate of faults by water is small.

Meanwhile, as described above, the water taking apparatus 1 of the present invention can be connected to a drone (not shown) and can be moved. Therefore, the user can not directly move to the water sampling point, and the user's convenience can be improved.
