Description

Water sampling and depth measuring device for drones

[0001] The present embodiments relate to a water sampling and depth measuring device for a drone mounted on a drone to automatically perform brine sampling and depth measuring.

[0002] To produce lithium, the process involves evaporating naturally occurring low-concentration brine to convert it into high-concentration brine, which is then supplied to a brine production plant.

[0003] In this process, a brine pond that stores brine of various concentrations in stages is used.

[0004] Here, the depth and salinity of the pond change depending on the amount of evaporation, and for accurate brine concentration, the depth of each pond must be measured regularly, and an ICP (Inductively Coupled Plasma) analysis must be performed by collecting a brine sample of at least 10 ml to check whether the brine concentration reaches the target value.

[0005] At this time, since the water depth of each pond is related to the brine concentration rate, field operators manually measure the water depth and collect brine samples to predict and manage brine production.

[0006] However, manually measuring water depth and collecting brine samples leads to reduced work efficiency and difficulties in securing accurate data.

[0007] Therefore, a device is required to enable multi-point water sampling and to accurately measure water depth.

[0008] These embodiments provide a water sampling and depth measuring device for a drone that can improve measurement accuracy by enabling accurate measurement and monitoring of the pond's depth through a first lifting / lowering module and a measuring module, and improve work efficiency by enabling sampling from multiple points through multiple second lifting / lowering modules and multiple water sampling modules that operate individually.

[0009] In one aspect, the embodiments comprise: a main body mounted on the lower part of a drone and having a chamber formed therein; a first lifting / lowering module installed in the chamber that winds or unwinds a wire and raises or lowers a measurement module connected to the wire; a second lifting / lowering module installed in the chamber that winds or unwinds a wire and raises or lowers a water sampling module connected to the wire; and a main control unit that controls the first lifting / lowering module so that the measurement module measures water depth or monitors the underwater environment, and controls the second lifting / lowering module so that the water sampling module collects a brine sample. A water sampling and depth measurement device for a drone may be provided, comprising: a communication module that provides position and altitude information data transmitted from the drone to the main control unit; wherein the main control unit calculates the ascending and descending distance of the first ascending and descending module or the second ascending and descending module according to the position and altitude information of the communication module and provides the calculated distance information to the first ascending and descending module or the second ascending and descending module, and transmits a control signal to measure water depth and monitor the underwater environment or transmits a control signal to collect a brine sample.

[0010] According to the embodiments, a water sampling and depth measuring device for a drone can be provided that can improve measurement accuracy by enabling accurate measurement and monitoring of the pond's depth through the first lifting and lowering module and the measuring module.

[0011] In addition, a water sampling and depth measuring device for a drone can be provided that can improve work efficiency by enabling samples to be collected at multiple points through multiple individually operating second lifting and lowering modules and multiple water sampling modules.

[0033] Referring to FIGS. 1 to 15, a water sampling and depth measuring device (20) for a drone according to one aspect of the present embodiment comprises: a main body (100) mounted on the lower part of a drone (10) and having a chamber formed inside; a first lifting / lowering module (110) installed in the chamber that winds or unwinds a wire (W) and raises or lowers a measuring module (200) connected to the wire (W); a second lifting / lowering module (130) installed in the chamber that winds or unwinds a wire (W) and raises or lowers a water sampling module (300) connected to the wire (W); and a main control unit (160) that controls the first lifting / lowering module (110) so that the measuring module (200) measures the depth or monitors the underwater environment, and controls the second lifting / lowering module (130) so that the water sampling module (300) collects a brine sample. It includes a communication module (162) that provides location and altitude information data transmitted from the drone (10) to the main control unit (160); wherein the main control unit (160) calculates the ascending and descending distance of the first ascending and descending module (110) or the second ascending and descending module (130) according to the location and altitude information of the communication module (162), provides the calculated distance information to the first ascending and descending module (110) or the second ascending and descending module (130), and transmits a control signal to the first ascending and descending module (110) to measure water depth and monitor the underwater environment, or transmits a control signal to the second ascending and descending module (130) to collect a brine sample.

[0034] To produce lithium, the process involves evaporating naturally occurring low-concentration brine to convert it into high-concentration brine, which is then supplied to a brine production plant.

[0035] In this process, a brine pond that stores brine of various concentrations in stages is used.

[0036] Here, the depth and salinity of the pond change depending on the amount of evaporation, and for accurate brine concentration, the depth of each pond must be measured regularly, and an ICP (Inductively Coupled Plasma) analysis must be performed by collecting a brine sample of at least 10 ml to check whether the brine concentration reaches the target value.

[0037] At this time, since the water depth of each pond is related to the brine concentration rate, the pond depth is measured and brine samples are collected to predict and manage brine production.

[0038] The water sampling and depth measuring device (20) for a drone in this embodiment measures the depth of a pond through a first lifting / lowering module (110) and a measuring module (200), and collects samples from multiple points through multiple second lifting / lowering modules (130) and multiple water sampling modules (300) that operate individually.

[0039] At this time, the drone (10) transports the drone water sampling and depth measuring device (20) to a designated location in the pond, and returns to the field operator when the water sampling and depth measuring of the drone water sampling and depth measuring device (20) is completed.

[0040] Here, the water sampling and depth measuring device (20) for a drone performs water sampling and depth measuring by unwinding the wire (W) of the first lifting / lowering module (110) or the second lifting / lowering module (130) to lower the measuring module (200) or the water sampling module (300) into the pond, or by winding up the wire (W) of the first lifting / lowering module (110) or the second lifting / lowering module (130) to retrieve the measuring module (200) or the water sampling module (300).

[0041] Here, the field operator operates the drone (10) through a controller or operates the water sampling and depth measuring device (20) for the drone to measure the depth and collect brine.

[0042] Such a controller transmits and receives signals using a wireless communication protocol with the drone (10) or the water sampling and depth measuring device (20) for the drone, and controls the drone (10) or the water sampling and depth measuring device (20) for the drone.

[0043] In this embodiment, the drone (10) or the water sampling and depth measuring device (20) for the drone is connected to a smartphone via Wi-Fi, so that the drone (10) or the water sampling and depth measuring device (20) for the drone can be controlled by the smartphone without a controller, or signals can be exchanged between the drone (10) or the water sampling and depth measuring device (20) for the drone and the smartphone.

[0044] For example, the drone (10) and the water sampling and depth measuring device (20) for the drone can transmit and receive control signals or depth measuring data signals using wireless communication protocols such as radio frequency (RF) communication, satellite communication, cellular network, Bluetooth, and Wi-Fi.

[0045] The water sampling and depth measuring device (20) for a drone according to the present embodiment includes a main body (100), a first lifting / lowering module (110), a second lifting / lowering module (130), a main control unit (160), a communication module (162), a measuring module (200), and a water sampling module (300).

[0046] The main body (100) is mounted on the lower part of the drone (10) via a coupling bracket (108), and a chamber is formed in which a first lifting / lowering module (110), a second lifting / lowering module (130), a main control unit (160), and a communication module (162) are installed.

[0047] More specifically, the main body (100) comprises: a main frame (102) mounted on the lower part of the drone (10) and forming a chamber inside; an outer panel (104) coupled to the main frame (102) so as to seal the chamber; and an inner panel (106) coupled to the main frame (102) to partition the chamber.

[0048] The main frame (102) is formed in the shape of an enclosure that forms a chamber inside, thereby stably protecting the first lifting / lowering module (110), the second lifting / lowering module (130), the main control unit (160), and the communication module (162) installed in the chamber.

[0049] The outer panel (104) is connected to the main frame (102) so as to seal the chamber, thereby blocking the chamber from the outside and forming a sealed space.

[0050] The inner panel (106) is connected to the main frame (102) to partition the chamber and prevent interference between parts.

[0051] In this embodiment, the chamber comprises: a first chamber (S1) formed on the front side and having a first lifting / lowering module (110) disposed therein; a second chamber (S2) formed on the rear lower side partitioned by an inner panel (106) and having one or more second lifting / lowering modules (130) disposed therein; and a third chamber (S3) formed on the rear upper side partitioned by an inner panel (106) and having a main control unit (160) and a communication module (162) disposed therein.

[0052] The first lifting / lowering module (110) is installed in the first chamber (S1) and winds or unwinds the wire (W) to raise or lower the measuring module (200) connected to the wire (W).

[0053] More specifically, the first lifting / lowering module (110) comprises: a first support frame (111) installed in the first chamber (S1); a first winding unit (114) rotatably installed on the first support frame (111) and rotating in one direction or opposite direction by the driving force of the first driving unit (113) to wind or unwind a wire (W) and to lift / lower the measuring module (200); a first driving control unit (116) that calculates the rotation direction and number of rotations of the first winding unit (114) according to distance information from the main control unit (160) and controls the first driving unit (113) so that the first winding unit (114) rotates according to the calculated rotation direction and number of rotations; and a first braking unit (115) that fixes the first winding unit (114) according to the control signal of the first driving control unit (116) to maintain the distance between the main body (100) and the measuring module (200).

[0054] The first support frame (111) is a structure installed in the first chamber (S1) and stably fixes and supports the first cover (112), the first driving unit (113), the first winding unit (114), the first braking unit (115), the first driving control unit (116), and the first transfer unit (120).

[0055] The first driving unit (113) rotates the first winding unit (114) in one direction or the opposite direction according to the control signal of the first driving control unit (116).

[0056] The first winding unit (114) rotates in one direction or the opposite direction by the driving force of the first driving unit (113) to wind or unwind the wire (W) and raise or lower the measuring module (200).

[0057] At this time, the first cover (112) is coupled to the first support frame (111) to protect the first winding section (114) from the external environment (dust, water, impact, etc.) and covers the first winding section (114).

[0058] The first braking unit (115) fixes the first winding unit (114) so ​​that the main body (100) and the measurement module (200) maintain a set distance according to the control signal of the first driving control unit (116).

[0059] That is, the first braking unit (115) stops the rotation of the first winding unit (114) according to the control signal of the first driving control unit (116) so that the measurement module (200) can remain in a fixed position, and fixes the first winding unit (114) so ​​that the measurement module (200) does not move.

[0060] The first drive control unit (116) calculates the rotation direction and rotation speed of the first winding unit (114) according to the distance information of the main control unit (160), and controls the first drive unit (113) so that the first winding unit (114) rotates according to the calculated rotation direction and rotation speed.

[0061] That is, the first drive control unit (116) determines the rotation direction and rotation speed of the first winding unit (114) according to the distance information of the main control unit (160), and thereby controls the first drive unit (113) to precisely adjust the raising and lowering of the measurement module (200) so that the measurement module (200) can move accurately to the measurement position.

[0062] In addition, the first lifting / lowering module (110) further includes a first transfer unit (120) that guides the wire (W) so that the wire (W) being wound or unwound from the first winding unit (114) moves along the rotational center axis of the first winding unit (114) and is wound or unwound.

[0068] That is, the first guide section (125) guides the wire (W) to move along the rotational center axis of the first winding section (114), thereby preventing twisting or abnormal movement.

[0069] At this time, the first transfer shaft part (124) has a screw portion formed on its outer surface, and the first guide part (125) has a screw portion formed on the inner surface of the through hole through which the first transfer shaft part (124) passes, corresponding to the screw portion of the first transfer shaft part (124).

[0070] Accordingly, when the first transfer shaft (124) rotates in one direction or the opposite direction by the first winding part (114), the first guide part (125) moves to one side or the other side along the longitudinal direction of the first transfer shaft (124) and guides the movement of the wire (W) in the direction along the rotation center axis of the first winding part (114).

[0071] Here, the first lifting / lowering module (110) further includes a first support shaft (126) that supports the movement of the first guide part (125) by being coupled to the first support frame (111) parallel to the first transfer shaft part (124) so ​​that the first guide part (125) can move stably.

[0072] The first support shaft (126) is connected to the first support frame (111) so as to be positioned parallel to the first transfer shaft (124), and supports the movement of the first guide part (125).

[0073] Additionally, the first lifting / lowering module (110) further includes a first detection unit (127) for detecting the movement of the first guide unit (125) to limit the movement range of the first guide unit (125).
