Abstract

The present invention relates to a wasteway water level detecting system with improved reliability, which is manufactured to accurately detect overflow by a sensor while preventing plants extending to the bottom of a wasteway or climbing another objects from being covered, or water plants from growing or fallen leaves from being swept and entered in a location to detect overflow. Accordingly, a cylindrical induction member and a sensor installed in the same can fundamentally block plants extending to the ground or climbing another objects from covering a measurement position of the sensor so as not to hinder measurement. In addition, an unnecessary alarm due to a measurement error by a surrounding environment is prevented from being issued by introducing overflow into the cylindrical induction member in order to solve a problem of dew formation around a sensor or not evaporating moisture for a long time.

Description

Water level detection system on spillway with improved reliability

The present invention relates to a water level detection system for a Yeosuway with improved reliability, and more particularly, if it is covered with a plant that extends to the bottom of the Yeosuway or is rolled up in something else, or when aquatic plants grow or fallen leaves are swept in at the overflow measurement location, The present invention relates to a water level detection system in Yeosu-ro with improved reliability, which is manufactured so that an electrode sensor and a detection sensor can accurately detect overflow.

In general, a dam refers to a structure that is erected across a river to block the flow of a river, change the direction of the flow, and slow it down. These structures create artificial lakes or reservoirs.

In most cases, dams are equipped with a spillway or weir to discharge or overflow water.

Yeosu-ro is a waterway that enables safe and efficient discharge of floods exceeding the capacity to be accommodated in the allocated storage space or floods exceeding the capacity of the conversion system in the conversion dam.

The location of Yeosu-ro is selected in consideration of eco-friendly aspects as well as economic feasibility along with the dam.

When selecting the location of the Yeosuway in terms of topography, consider the angle between the access channel and the control unit with the dam center line, and the connection problem between the Yeosuway and the existing river through comparison and review of the format suitable for the site conditions.

Yeosu-ro selects a form that is advantageous in hydraulic and economic terms and is structurally safe.

Therefore, if possible, a straight open channel type should be chosen, and if an irrigation channel type is unavoidable, a sufficient margin of capacity should be provided.

In recent years, natural disasters caused by abnormal climate phenomena such as localized torrential rains and typhoons appear in various ways with each passing year.

Currently, domestic dam design standards do not provide a clear standard for the period required to exclude dam water in an emergency, so the size of emergency discharge facilities for each dam is designed and constructed differently depending on the designer's experience and supervision.

In addition, the dam is designed to not allow overflow in principle, so drainage that assumes overflow and overflow is not desirable.

In conclusion, the spillway is only designed for emergencies, and the flow of the spillway must be controlled by humans.

In addition, as shown in FIG. 1, there are many cases of exposure to nature due to the location of the Yeosu-ro, and when vines cover the periphery of the detection sensor, the sensing wave measurement is disturbed.

For example, a plant extending to the ground or wrapped around something else can cover the measurement position of the detection sensor and interfere with the measurement, and the detection wave can malfunction due to external obstructions such as floating objects.

In particular, as shown in FIG. 1, dew condensation on plants or arrowroots under the detection sensor, or rainwater caused the detection sensor to be mistaken for overflow and sound an alarm.

Meanwhile, the detection sensor measures the reflection time by emitting a detection wave in a non-contact method, and calculates the difference between the reflection time from a reference surface without water to measure the amount of water.

However, the sensing wave is sensitive to temperature and humidity, and the emitted sensing wave is reflected by an object other than water, so it cannot be accurately measured.

In addition, the detection sensor that is exposed to the outside for a long time is very sensitive to temperature and humidity such as dew and fog, and has the disadvantages of frequent breakdowns and short replacement cycles.

As a conventional invention, Korean Patent No. 2013-0014706 is a water level detection system using a detection sensor including a power supply unit, a transmission/reception unit, a pump control unit, and a microcomputer unit, wherein the power supply unit includes a power stabilization circuit, and the transmission/reception unit stabilizes a signal. It provides a water level detection system using a detection sensor comprising a circuit stage and a time shift adjustment unit, wherein the transmission and reception unit is installed in the storage and transmits and receives a signal value of the detection sensor.

However, there was a problem in that it was necessary to continuously maintain and repair the malfunction and damage of the detection sensor that may occur due to impurities or obstacles in the liquid in the storage.

Korean Patent Laid-Open Publication No. 2010-0001900 relates to a measuring tube for measuring a flow rate, a sensing sensor fixed to a side wall of the measuring tube, and a sensing wave transmission time difference type flow meter provided on both sides of the measuring tube for pipe connection, A first sensor is provided on one side wall of the measurement tube, a reflector is provided on a side wall of the measurement tube located in the traveling direction of the detection wave beam emitted from the first sensor, and the detection wave beam reflected by the reflector A second sensor is provided on the sidewall of the measuring tube located in the direction of movement of the first sensor, the reflector, and the second sensor using a reflection path formed in that order, or the second sensor, the reflector, and the first It provides a sensing wave flowmeter, characterized in that using a reflection path formed in the order of the sensor.

However, there is a problem in that reliable measurement data cannot be continuously detected because the support must be formed perpendicular to the measuring tube when the sensor is installed, and the angle of the vibrator must be adjusted to adjust the angle of emission or reception of the sensing wave beam. .

This stored control unit (not shown) is attached to the case unit 10 or the like.

This is because, when the detection sensor 18-1 is used first, there is a high probability of a malfunction due to ambient moisture, whereas the electrode sensor member 25 does not show a malfunction by directly contacting the electrode.

For this purpose, an electrode 25-1 and an electrode sensor 25-2 are formed inside the electrode sensor member 25.

Here, the power line 15-1 of the electrode 25-1 is protected through the power line protection tube 15, and receives power from the outside.

The guide member 20 or the bottom member 30 is provided with inlet portions 32 and 33 and an outlet path 34 so that even when fallen leaves are swept in, ride the inclined back of the triangular blade 31 to the outside of the floor member. Since the overflow is discharged to the outside along the periphery, the overflow is not disturbed and flows into the interior of the induction member 20 or the bottom member 30, so that the detection sensor 18-1 can accurately measure the overflow.

That is, in the present invention, when fallen leaves are swept away from the outside toward the guiding member 20 made of stainless material, the inside is empty, because it is discharged to the outside along the outer periphery of the triangular wing 31 or the bottom member.

The laser distance sensor may be implemented in a structure capable of multi-point measurement to overcome the limitation of a conventional laser sensor measuring one point. Specifically, the laser distance sensor may be coupled to a motor that moves up and down and a motor that moves left and right, and may measure the height of the overflow corresponding to a position corresponding to each of a plurality of measurement points on the floor.

In addition, the laser distance sensor may increase the number of measurement points by setting the distance between the plurality of points to be narrower.

Alternatively, a multi-point detection sensor capable of observing the initial overflow amount as an average value may be used through multi-point measurement by scanning a plurality of points using a laser from the top for more precise measurement of overflow.
