Description

Flow rate and water quality measuring device for rivers

The present invention provides a flow rate for a river that can ultimately predict the flow rate and water quality change of a river (or river, lake, etc.) through measurement values such as water level, flow rate, water quality, similar amount, river bed fluctuations, precipitation and runoff It is related to the water quality measurement device.

In more detail, it relates to a flow rate and water quality measuring device for a river that can measure the above measurement values unattended while being installed in a river at all times and autonomously traversing by natural energy and minimum supply power.

Accurately measuring the flow rate and water quality of rivers (or lakes) has an important meaning for muddy water, flood management, water resource management, and design and construction of water 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 on-site measurement methods have been proposed and developed according to these efforts.

Currently, ADCP (Acoustic Doppler Current Profiler), one of the latest technologies, uses the Doppler effect of ultrasound to measure the flow velocity and analyze the degree of disturbance in water. This is a method of estimating an autocorrelation function or FFT (Fast Fourier Transform) spectrum for a pulse signal.

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

In ADCP, it is difficult to measure the accurate flow rate for 10% below the water level and 10% at the bottom, so the final value is derived by the flow rate calculation method based on theoretical assumptions.

Therefore, even with the latest flow measurement method, there is a high possibility that it basically includes a flow measurement error of about 20%, and in practice, it is common to have a measurement error of about 5 to 15%. If this measurement error can be reduced to less than 5%, more efficient and accurate management will be possible.

Meanwhile, as described above, the most accurate method for measuring the current flood volume is to calculate the flow rate by obtaining the water depth and the flow velocity profile at the point using a flow rate measuring boat crossing the river.

In particular, the new method of measuring the flow rate using ADCP is known to bring about an improvement in accuracy of within about 5% compared to other existing flow rate measurement methods, so 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 measuring the flow moves both sides (the starting position and the arrival position) of the river to match the river flow rate measurement principle.

However, in the flow measurement method using ADCP as described above, since the flow measurement boat has been manually controlled by the remote control, even a skilled person can determine the starting and arriving positions of the flow measurement boat in speed and direction in bad weather conditions such as high flow speed or windy conditions. It is difficult to control the movement to fit the

In addition, since the flow measurement boat is operated by the power supplied by the entire amount, the maintenance cost is high, and since it is manually operated by the remote control, a driver must be resident at the site while the flow measurement boat is being operated, and the stopped operation of the flow measurement boat It also has to be collected, so there is an inconvenience in maintaining and managing it.

In relation to this, the flow measurement information may be difficult to continuously measure because the operation is stopped when the power is cut off during manual operation or the driver is in a situation where the remote control cannot be operated due to, for example, bad weather or bad weather. It is pointed out that there is a problem of loss during periods of rapid flow or floods.

The present invention is to solve the above problems, and an object of the present invention is to automatically measure measurement values such as water level, flow rate, water quality and similarity, river bed fluctuations, precipitation, and runoff while always installed in the river.

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

The pickup electric winch 200 is installed on a river structure (for example, a bridge (b), see FIGS. ) is supported in a towing state, and the docking station 300 and the unmanned moving measurement object 400 are evacuated when the measurement operation cannot be performed due to bad weather such as flooding.

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 receiver 211 for receiving a bad weather signal or a control signal from a base station transmitted from the outside.

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

The pickup electric winch 200 pulls up the anchoring station 300 and the unmanned moving measurement body 400 over the bridge or an evacuation groove provided at the edge of the river ( Evacuation by A) in FIGS. 4 and 5 enables evacuation from bad weather such as floods.

Conversely, upon receiving a wake-up signal or a measurement work restart signal from the base station to the receiver 211, the pickup electric winch 200 is reversely driven by the first controller 210 to unwind the pickup rope 201. By doing so, the measurement operation can be resumed.

On the other hand, the pickup electric winch 200 may further include a storage battery 220 for its driving (see FIG. 6 ). In other words, power is required to rotationally drive the rope bobbin of the pickup electric winch 200, and the required power converts natural energy (solar light, river currents, wind power, etc.) into electrical energy, and the converted electrical energy is a storage battery It can be used for rotational driving of the rope bobbin by storing electricity in 220 , and can be used simultaneously as a power source of the first controller 210 .

Here, the pickup electric winch 200 is operated intermittently in case of emergency, so there is no continuous power consumption, so it is not necessary to install a power storage sensor, but may be installed as necessary.

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

The docking station 300 is installed in a floating state in a river and is used to pull and support the unmanned mobile measuring body 400 and to temporarily or temporarily anchor the unmanned moving measuring body 400 .

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

Here, the traction rope 321 is preferably a floating rope floating on the water surface is applied. The reason is that since the rope sinking in water is heavy, it may cause a problem of arbitrarily pulling the unmanned moving measurement body 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.

When a bad weather signal is received from the first controller 210, the second controller 330 receives a fuel charging request signal from a third controller (to be described later) of the unmanned movement measurement object 400, unmanned movement measurement In a situation that requires anchoring, such as when repair of the sieve 400 is required, by driving the traction electric winch 320 and winding the unwinding traction rope 321, the unmanned moving measurement body 400 is transferred to the station body ( 310) to enable anchoring of unmanned moving measurement objects by pulling and pulling.

As shown in FIG. 7 , the station body 310 may be provided with a U-shaped eyepiece groove 311 so that the front of the unmanned movement measurement body 400 enters and can be stably docked. Here, it is preferable that the inlet end of the eyepiece groove 311 has a flared shape to avoid collision when the unmanned moving measurement body 400 is berthed, and in addition, the inlet edge of the eyepiece groove 311 has a collision mitigation. For this, it is more preferable that the bumper 312 is installed.

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 measurement body 400 as shown in FIG. 8 . The fuel supply module 340 converts natural energy such as sunlight, river currents, and wind power into electrical energy and stores power to charge the unmanned moving measurement body 400, as well as an electric winch 320 and a second controller ( The first storage battery 341, which serves to supply power to 330), is disposed on the inner surface of the eyepiece groove 311 of the station body 310, and is an unmanned moving measurement body in any one of a magnetic induction method and a magnetic resonance method. It may include a charging pad 342 for wirelessly charging electric fuel.

In the magnetic flow method, charging is performed through contact between the pads, and in the magnetic resonance method, charging is possible in a non-contact state between the pads.

On the other hand, the docking station 300 may be provided with a power storage amount detection sensor 350 for detecting the amount of power storage of the first storage battery 341 in real time, and when the detected amount of power is less than the reference value, the second controller 330 can stop the operation of the traction electric winch until it reaches the reference value despite the time when the operation of the traction electric winch 320 is required.

The unmanned moving measurement 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 traction rope 321 and measured values (water level, flow rate, similar amount, river bed fluctuations, precipitation, runoff, etc.), and has a characteristic configuration that measures the measured value while automatically crossing the river.

The unmanned moving measurement body 400 includes a measurement body 410 connected to the end of the traction rope 321, and a measurement device 420 mounted on the measurement body to measure the measured value, as shown in FIGS. 9 to 11, 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 water.

Here, the measurement body 410 may have a modular structure that can be disassembled and assembled as shown in FIG. 9 . The modular structure is easier to install and collect than the integrated structure, and has the advantage of reducing maintenance costs because only damaged or damaged parts can be exchanged locally.

As shown in FIG. 10, the measuring device 420 includes a measuring unit 421 that measures the measured values (water level, flow rate, similar amount, river bed variation, precipitation, runoff, etc.), and the value measured by the measuring unit. It may be composed of 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 measuring equipment 420 may include an ultrasonic flow meter, electromagnetic wave or laser anemometer, and the part where the flow rate measurement of the water surface by the ultrasonic flow meter is impossible is supplemented by electromagnetic wave and laser anemometer, and these measured values are measured. Combining them can lead to more precise measurements.

The unmanned movement measurement 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 current, and wind power into electrical energy and stores electricity, and uses electric fuel with measuring equipment 420 and automatic crossing means 430. It may further include a second storage battery 451 to supply, and a supply and demand pad 452 that receives electric fuel by contact or non-contact with the charging pad 342 of the station body 310 and stores electricity in the second storage battery 451 . can

The automatic crossing means 430 may include a rudder (431: see FIG. 12) for controlling the left and right movement direction of the unmanned moving measurement object 400 while being operated by power supplied from the second storage battery 451. . Here, the rudder 431 automatically changes the left and right angles by the third controller 440 in response to the flow direction of the river (the direction of the A arrow in FIG. 12), so that the repeating traversing of the moving measurement body 400 is possible do.

For example, as in FIG. 12 , when the rudder 431 coincides with the water flow direction, the unmanned moving measurement body 400 is located in the center without a change in position, since the angle of the rudder and the water flow direction coincide, and from this, the rudder When the angle of (431) is turned in a counterclockwise direction, the leftward movement of the unmanned moving measurement body 400 is possible by the water current acting on the rudder, and when the angle of the rudder 431 is turned in the clockwise direction, the rudder ( 431), the rightward movement of the unmanned movement measurement body 400 is possible by the action of the water current. The angle change of the rudder 431 is made automatically, and automatic traversing of the unmanned moving measurement body is possible.

The unmanned moving measurement object 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 amount of storage is less than the reference value, the third controller 440 is By sending a mooring request signal to the second controller 330 of the mooring station 300, the mooring is accomplished 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 moving measurement body 400 maintains a state spaced apart from the docking station 300 by the length of the tow rope 321 unwound by the water flow of the river, and the automatic crossing means 430 ), while drawing an arc-shaped trajectory (arrow B in FIG. 12) centered on the docking station 300, automatically and repeatedly traverses in the width direction of the river to measure the measured value.

In particular, the unmanned moving measurement object 400 can secure a lot of measurement data because it is possible to measure 24/7 except for a reason such as a special bad weather situation or a malfunction. Therefore, accurate measurement is possible, and in particular, taking into account that the measured values may differ in the central and side portions of the river, the unmanned moving measuring object derives the measured values while repeatedly traversing the river, so precise measurement is possible. Therefore, it is of great help in accurately predicting river flow.

On the other hand, the unmanned moving measurement body 400 may perform a measurement operation without a traction rope. That is, when the water flow in the river is small, the unmanned moving measurement object 400 does not float away even if the traction rope 321 is not connected. By approaching the docking station 300, it is possible to perform operations such as wireless charging.

On the other hand, when the unmanned movement measurement object 400 is trying to connect the traction rope 321 due to the occurrence of a water flow while performing measurement work in a rope-free state, the unmanned movement measurement object 400 is driven by the propulsion power to the docking station 300 At the same time as being docked by moving to a hook (not shown) provided at the end of the traction rope 321, the hook (not shown) of the unmanned moving measurement body 400 is caught and the traction rope 321 can be automatically connected. Thereafter, the measurement operation can be resumed while the traction rope 321 is connected.

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

In this case, the unmanned moving measurement 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 wire (not shown) such as a fishing line or a piano wire. there is. Here, an electric motor may be additionally installed for winding and unwinding of the guide wire.

According to this configuration, the guide line guides the location of the unmanned mobile measurement body 400 or when it is picked up due to bad weather, pulls the unmanned mobile measurement object 400 until it approaches the bridge and the berth, When picking up on the bridge and at the berth, a large force is required, so the role can be divided by pulling it up by the pickup rope 201 .

As described above, those skilled in the art to which the present invention pertains will be able to understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, it should be understood that all of the embodiments described above are illustrative and not restrictive. The scope of the present invention should be construed as being included in the scope of the present invention, rather than the above detailed description, all changes or modifications derived from the meaning and scope of the claims to be described later and their equivalent concepts.
