Description

Stream flow and water quality measuring apparatus

The present invention is a river flow rate that can ultimately predict the flow rate and water quality change of a river through measurement values such as the water level, flow rate, water quality, sediment amount, fluctuation situation of the river bed, precipitation and runoff amount, etc. of a river (or river, lake, etc.) It relates to a water quality measuring device.

More specifically, it relates to a flow rate and water quality measuring device for a river capable of unattended measurement of the above measured values while autonomously traversing by natural energy and minimum supply power while being installed in a river at all times.

Accurately measuring the flow rate and water quality of a river (or lake) has important implications for runoff, flood management, water resource management, design and construction of water-based structures, and water environment management.

Therefore, the state has made efforts to accurately measure the flow rate and water quality of national rivers through specialized agencies, and various field measurement methods have been proposed and developed according to these efforts.

Currently, one of the latest technologies, ADCP (Acoustic Doppler Current Profiler), measures the flow velocity in water and analyzes the degree of disturbance by using the Doppler effect of ultrasonic waves. It is a method of estimating an autocorrelation function or a Fast Fourier Transform (FFT) spectrum for a pulse signal.

The ADCP measures the flow rate by measuring the flow velocity profile and depth while crossing the river, and for this purpose, a flow rate measurement information controlled remotely is used.

For ADCP, it is difficult to accurately measure the flow rate at 10% below the surface and 10% above the bottom, so the final value is derived using a flow rate calculation method based on theoretical assumptions.

Therefore, even with the latest flow rate measurement method, there is a high possibility that a flow measurement error of about 20% is basically included, and in fact, it is common to have a measurement error of about 5 to 15%. If these measurement errors can be reduced to within 5%, more efficient and accurate management will be possible.

On the other hand, as described above, the most accurate method of measuring the current amount of flood is a method of calculating the flow rate by obtaining a depth of water and a flow velocity profile at that point using a flow measurement boat crossing a river.

In particular, since the new method of measuring flow rate using ADCP is known to bring about 5% improvement in accuracy compared to other existing flow rate measurement methods, the use cases are rapidly increasing in recent years.

At this time, in order to measure the flow rate of the river more accurately, it is important that the boat for flow measurement moves both sides of the river (starting position and arrival position) in accordance with the river flow measurement principle.

However, in the flow measurement method using the ADCP described above, since the flow rate measurement information has been manually controlled by the remote control, even the skilled person determines the starting position and the arrival position of the flow measurement boat in bad weather conditions such as fast flow or wind. It is difficult to control the movement accordingly, and this causes a problem that the error of the measured value increases.

In addition, since the flow rate measurement information is operated entirely by the supply power, maintenance costs are high, and since it is operated manually by the remote control, the driver must remain at the site while the flow measurement information is being operated, and the flow measurement information that has been stopped must be stored. Since it must be collected, there is inconvenience in maintaining and managing it.

In relation to the flow rate measurement data, continuous measurement may be difficult because the operation is stopped when the power is cut off during manual operation or the driver is unable to operate the remote control due to, for example, bad weather or bad weather. It is pointed out a problem that is lost in times of high flow rate or flooding.

As shown in the accompanying drawings, the flow rate and water quality measurement device for a river (hereinafter abbreviated as'flow rate measurement device', 100) according to the present invention is a value to be measured while being installed in a river (or lake) at all times without power. (Water level, flow rate, similar amount of river, fluctuations in river bed, precipitation, runoff, etc.: hereinafter referred to as'measured value') can be accurately measured unattended, pickup electric winch 200, docking station 300 and unmanned It may include a movement measuring body 400.

The pickup electric winch 200 is installed on a structure of a river (for example, a bridge (b), see FIGS. 1 to 3) or an edge of a river (see FIGS. 4 and 5), and the docking station 300 and the unmanned movement measuring body 400 ) Is supported in a traction state, and the docking station 300 and the unmanned moving measuring body 400 are evacuated when the measurement cannot be performed due to bad weather such as a flood.

Here, the pickup electric winch 200 may be automatically controlled by the first controller 210 as shown in FIG. 6. The first controller 210 may include a receiving unit 211 for receiving a bad weather signal transmitted from the outside or a control signal of a base station.

Accordingly, when a bad weather signal is received by the reception unit 211 or a control signal from the base station is received, the pickup electric winch 200 is driven by the first controller 210 to perform an evacuation operation.

The pick-up electric winch 200 raises the berth station 300 and the unmanned moving measuring body 400 over a bridge or an evacuation groove provided at the edge of a river as it winds the pickup rope 201 during evacuation work. By evacuating in Figs. 4 and 5A), it is possible to evacuate from bad weather such as floods.

On the contrary, when a wake-up signal or a measurement operation resume signal is received from the base station by the receiving unit 211, the pickup rope 201 is unwinded by reverse driving the pickup electric winch 200 by the first controller 210. By doing so, the measurement operation can be resumed.

Meanwhile, the pick-up electric winch 200 may further include a storage battery 220 to drive the pick-up electric winch 200 (see FIG. 6). In addition, power is required to rotate the rope bobbin of the pickup electric winch 200, and the required power converts natural energy (solar power, river water current, wind power, etc.) into electrical energy, and the converted electrical energy is a storage battery. By storing electricity in 220, it can be used to drive the rotation of the rope bobbin, and can be used simultaneously as a power source of the first controller 210.

Here, since the pickup electric winch 200 is intermittently operated in an emergency, there is no continuous power consumption, so it is not necessary to install a power storage amount detection sensor, but it may be installed if necessary.

For reference, in order to use natural energy, it is obvious that a condensing panel for condensing sunlight, a water wheel for collecting water flow power, and a windmill for collecting wind power may be installed, so a detailed description thereof will be omitted. .

The docking station 300 is installed in a floating state in a river to traction and support the unmanned movement measuring body 400, and is used when the unmanned movement measuring body 400 is temporarily or temporarily anchored.

The docking station 300 is connected to the end of the pickup rope 201 of the pickup electric winch 200 and is in a traction state, as shown in FIGS. 1-5 and 7-8, and can be installed in a floating state on the water surface of a river. A traction electric winch 320 for winding or unwinding a station main body 310 having a floating structure and a traction rope 321 that is traction the unmanned movement measuring body 400 while installed in the station main body, and a traction electric winch It may be composed of a second controller 330 for controlling the operation of.

Here, it is preferable that the traction rope 321 is applied with a floating rope floating on the water surface. The reason is that the weight of the rope sinking in water is heavy, so it may cause a problem of arbitrarily pulling the unmanned moving measuring object 400 connected to the end while sinking in the water, and the load is large during winding and unwinding. This is because a high-capacity electric winch 320 is required.

The second controller 330 measures unmanned movement when a bad weather signal is received from the first controller 210, when a fuel charging request signal is received from a third controller (to be described later) of the unmanned movement measuring body 400. When anchoring is required, such as when the sieve 400 needs to be repaired, the traction electric winch 320 is driven to wind the unwinded traction rope 321 to transfer the unmanned movement measuring body 400 to the station main body ( It is possible to anchor the unmanned moving measuring object by pulling it to 310).

As shown in FIG. 7, the station main body 310 may be provided with a U-shaped eyepiece groove 311 so that the front of the unmanned movement measuring body 400 enters the interior and can be stably eyed. Here, it is preferable that the entrance end of the eyepiece groove 311 has a shape expanded in a trumpet shape in order to avoid a collision when the unmanned movement measuring body 400 is berthing, and also, collision mitigation at the entrance side edge of the eyepiece groove 311 It is more preferable that the bumper 312 is laid for it.

As shown in FIG. 8, the docking station 300 may further include a fuel supply module 340 for supplying electric fuel to a fuel supply module (to be described later) of the unmanned movement measuring body 400. The fuel supply module 340 converts natural energy such as sunlight, river water, and wind power into electric energy and stores it to charge the unmanned movement measuring body 400, as well as the electric winch 320 and the second controller ( The first storage battery 341 that serves to supply power to the 330 and the unmanned moving measuring body is arranged on the inner surface of the eyepiece 311 of the station main body 310 by either a magnetic induction method or a magnetic resonance method. It may include a charging pad 342 for wirelessly charging electric fuel.

The magnetic flow method is charged through contact between pads, and the magnetic resonance method is capable of charging in a non-contact state between pads, and can be selected and applied as needed.

On the other hand, the docking station 300 may be installed with a power storage amount detection sensor 350 that detects the power storage amount of the first storage battery 341 in real time, and when the detected power storage amount is less than the reference value, the second controller 330 Even though the operation of the traction electric winch 320 is required, the operation of the traction electric winch may be stopped until the reference value is reached.

The unmanned movement measuring body 400 is installed in a floating state on the water surface of the river, and is connected to the docking station 300 as a towing rope 321 and measured values (river level, flow rate, similar amount, fluctuation of river bed, precipitation, It is for measuring runoff, etc.), and has a characteristic configuration that measures the measured value while automatically traversing the river.

As shown in FIGS. 9 to 11, the unmanned movement measuring body 400 includes a measuring body 410 connected to the end of the traction rope 321, a measuring device 420 mounted on the measuring body to measure a measured value, It may be composed of an automatic crossing means 430 for automatically traversing the measurement body in the width direction of the river, and a third controller 440 for controlling the operation of the automatic crossing means.

The measurement body 410 is made of a material that can be suspended in water, and may have a streamlined boat shape for smooth flow in the water.

Here, the measurement body 410 may have a module structure capable of disassembling and assembling, as shown in FIG. 9. The module structure has advantages in that it is easier to install and collect than the one-piece structure, and because only damaged or damaged parts can be exchanged locally, maintenance cost can be reduced.

As shown in FIG. 10, the measurement equipment 420 includes a measurement unit 421 that measures a measurement value (water level, flow rate, similar amount of river, fluctuation status of river bed, precipitation, flow rate, etc.), and a value measured by the measurement unit. It may include a measurement value storage unit 422 to store and a measurement value transmission unit 423 for wirelessly transmitting the measurement value stored in the measurement value storage unit to the base station.

Here, the measurement equipment 420 may include an ultrasonic flow meter, an electromagnetic wave or a laser velocimetry, and a portion where the flow rate measurement of the water surface by an ultrasonic flow meter is impossible is supplemented by an electromagnetic wave and a laser velocimetry, and these measured values are measured. Combining can lead to more precise measurements.

The unmanned movement measuring body 400 may further include a fuel supply module 450 for receiving electric fuel from the fuel supply module 340 when anchored in the docking station 300.

As shown in FIG. 11, the fuel supply module 450 converts natural energy such as sunlight, river water, and wind power into electrical energy and stores it, and uses the measuring equipment 420 and the automatic cross-section means 430 to store electric fuel. The second storage battery 451 to be supplied, and a supply pad 452 for receiving electric fuel by contacting or non-contacting with the charging pad 342 of the station main body 310 and storing electricity into the second storage battery 451 may be further included. I can.

The automatic cross-section means 430 may include a rudder 431 (see FIG. 12) that is operated by power supplied from the second storage battery 451 and adjusts the left and right movement direction of the unmanned movement measuring body 400. . Here, the rudder 431 automatically changes the left and right angles by the third controller 440 in response to the water flow direction of the river (in the direction of the arrow A in FIG. 12), so that the moving measurement object 400 can be repeatedly cross-sectioned. do.

For example, as shown in FIG. 12, when the rudder 431 coincides with the water flow direction, the rudder angle and the water flow direction coincide, so that the unmanned movement measuring body 400 is located in the center without any change in position, from which the rudder If the angle of 431 is turned in a counterclockwise direction, water flow acts on the rudder, so that the unmanned movement measuring body 400 can be moved to the left, and if the angle of the rudder 431 is turned clockwise, the rudder ( As the water flow acts on the 431), it is possible to move the unmanned movement measuring body 400 to the right. The angle change of the rudder 431 is performed automatically, and automatic traversing of the unmanned moving measurement object is possible.

The unmanned movement measuring body 400 may be provided with a power storage amount detection sensor 460 that detects the amount of charge of the second storage battery 451 in real time, and when the detected power storage amount is less than the reference value, the third controller 440 is The anchoring request signal is transmitted to the second controller 330 of the anchoring station 300 so that anchoring is performed by the operation of the traction electric winch 320 and charging can be performed at the same time.

As shown in FIG. 12, the unmanned movement measuring body 400 maintains a state spaced apart from the docking station 300 by the length of the traction rope 321 unwinded by the water current of the river, and the automatic crossing means 430 ), while drawing an arc-shaped trajectory (arrow B in FIG. 12) around the docking station 300, it automatically crosses the river in the width direction and measures the measured value.

In particular, since the unmanned moving measuring body 400 can be measured 24/7 except for reasons such as special bad weather conditions or failures, a lot of measurement data can be secured. Therefore, accurate measurement is possible, and in particular, taking into account that measurement values may vary in the center and side portions of the river, the unmanned moving measurement object repeatedly traverses the river and derives the measurement value, thereby enabling precise measurement. Therefore, it is of great help in accurately predicting river flow.

On the other hand, the unmanned movement measuring body 400 may perform a measurement operation without a traction rope. That is, if the water flow in the river is small, the unmanned moving measuring body 400 does not float without connecting the towing rope 321, so measurement can be performed without a towing rope, and if necessary, by GPS guidance and self-charging power. It is possible to access the docking station 300 to perform tasks such as wireless charging.

On the other hand, when the unmanned moving measuring body 400 is measuring in a no-rope state and wants to connect the traction rope 321 due to the occurrence of water flow, the unmanned moving measuring body 400 is docked by the propulsion power. While moving to and docking, the traction rope 321 can be automatically connected while the hook (not shown) provided at the end of the traction rope 321 is hooked on the hook (not shown) of the unmanned movement measuring body 400. Thereafter, the measurement operation can be resumed while the traction rope 321 is connected.

On the other hand, the flow measurement device 100 for a river according to the present invention is a simple configuration of a pickup electric winch 200 and an unmanned movement measuring body 400, excluding the configuration of the docking station 300 as another embodiment. I can.

In this case, the unmanned movement measuring body 400 is connected by the pickup electric winch 200 and the pickup rope 201, and can be separately connected by a strong but thin guide line (not shown) such as a fishing line or a piano line. have. Here, an electric motor may be additionally installed for winding and unwinding of the guide wire.

According to this configuration, the guide line serves to induce the position of the unmanned motion measuring object 400 or pull the unmanned motion measuring object 400 until it is close to the bridge and the berth when picking up due to bad weather, When picking up on the bridge or at the berth, a large force is required, so it is possible to share the role by pulling up by the pick-up rope 201.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, all of the embodiments described above are illustrative and should be understood as non-limiting. The scope of the present invention should be construed as including all changed or modified forms derived from the meaning and scope of the claims to be described later rather than the above detailed description, and equivalent concepts thereof.
