Description

배수로용 오물수거장치 및 그 제어방법{Apparatus for collecting sewage in a drainage and controlling method thereof}Apparatus for collecting sewage in a drainage and controlling method

본 발명은 하수처리장이나 배수펌프장, 취수장, 소규모 발전소 및 기타 산업하수처리장 등의 유입 수로에 설치하여 물의 흐름에 따라 흘러온 쓰레기(협잡물)를 수거하여 물의 흐름이 원활하도록 하는 배수로용 오물수거장치 및 그 제어방법에관한 것으로서, 더욱 상세하게는 유입수로를 따라 흐르는 물의 수위에 비례하여 수거기의 운전속도를 자동으로 제어함으로서 우천시와 같이 물의 유입이 많아질 경우 협잡물의 수거 속도를 신속히 하여 수로에 유입된 물의 흐름을 원할하게 할 수 있도록 하는 배수로용 오물수거장치 및 그 제어방법에 관한 것이다.The present invention is installed in an inlet canal such as a sewage treatment plant or drainage pumping station, intake station, small-scale power plant and other industrial sewage treatment plant to collect the waste (cold matter) flowing in accordance with the flow of water, and the waste water collection device for drainage to smooth the flow of water As a control method, in more detail, it automatically controls the operating speed of the collector in proportion to the water level flowing along the inflow channel, so that when the inflow of water increases, such as during rainy days, the collection speed of the contaminants is increased. The present invention relates to a sewage collection device for drainage channels and a control method thereof for smoothly flowing water.

일반적으로 하수처리장이나 배수펌프장, 취수장 및 기타 산업하수처리장 등의 설치대(11)와 수로(10)의 바닥에는 구동스프라켓(21)과 종동스프라켓(22)이 각각 설치되고, 상기 구동스프라켓(21)과 종동스프라켓(22) 사이에는 체인(23)이 권선 설치되며, 상기 체인(23)의 양측에는 체인(23)을 보호하는 체인커버(24)가 설치되고, 상기 체인(23)에는 일정 간격으로 협잡물을 걷어 올리는 갈퀴(25)가 설치되며, 상기 구동스프라켓(21)은 콘트롤부(30)에 의해 제어되는 인양모터(26)로부터 회전동력을 받도록 되어 있다.In general, a driving sprocket 21 and a driven sprocket 22 are installed at the bottom of the installation table 11 and the water channel 10 of the sewage treatment plant, the drainage pumping station, the intake station, and other industrial sewage treatment plants, respectively, and the driving sprocket 21 The chain 23 is wound between the driven sprocket 22 and the chain 23, and a chain cover 24 that protects the chain 23 is installed at both sides of the chain 23, and the chain 23 is provided at a predetermined interval. A rake 25 is provided to lift the contaminants, and the drive sprocket 21 is adapted to receive rotational power from the lifting motor 26 controlled by the control unit 30.

상기와 같이 이루어진 종래의 배수로용 오물수거장치는 콘트롤부(30)의 제어에 의해 인양모터(26)가 구동되면 벨트 또는 체인과 같은 동력 전달기구에 의해 회전력이 구동스프라켓(21) 및 종동스프라켓(22)에 전달됨으로서 체인(23)이 체인커버(24) 내에서 일정한 궤도를 따라 회전하게 된다.In the conventional wastewater collecting device for drainage channels made as described above, when the lifting motor 26 is driven by the control of the control unit 30, the rotational force is driven by a power transmission mechanism such as a belt or a chain. As it is transmitted to 22, the chain 23 is rotated along a predetermined track in the chain cover 24.

이때, 수로(10) 내에 유입된 협잡물(40)은 체인커버(24)에 설치된 갈퀴(25)에 걷어 올려져 상승하게 되며, 구동스프라켓(21)이 위치한 지점에서 수거함(27)으로 낙하됨에 따라 수로(10)에 유입된 협잡물을 연속적으로 제거할 수 있는 것이다.At this time, the contaminants 40 introduced into the water channel 10 are lifted up by the rake 25 installed in the chain cover 24, and fall into the collection box 27 at the point where the driving sprocket 21 is located. The contaminants introduced into the channel 10 can be removed continuously.

이와 같은 종래 배수로용 오물수거장치는 콘트롤부(30)에서 인양모터(26)를 구동하는 속도가 고정되어 있으며, 이로 인해 협잡물(40)을 수거하는 갈퀴(25)가설치된 체인(23)의 회전속도가 일정하게 유지됨으로써 수로(10)에 유입되는 물의 수위나 수압등에 대하여 적절히 대응하지 못하는 문제점이 있는 것이다.Such a conventional wastewater collecting device for the drainage is fixed to the driving speed of the lifting motor 26 in the control unit 30, thereby the chain 23 is installed with a rake 25 for collecting the contaminants 40 Since the rotational speed is kept constant, there is a problem in that the water level or the water pressure of the water flowing into the waterway 10 cannot be coped properly.

즉, 우천 등으로 인하여 수로(10)의 수위가 상승할 경우 그 만큼 유속이 빠르게 진행되어 협잡물(40)의 유입량이 많아지게 되므로 물의 유입량에 비례하여 협잡물(40)의 제거속도 역시 빠르게 진행되어야 하나, 콘트롤부(30)에서 인양모터(26)를 구동하는 속도는 고정되어 수로(10)에 유입되는 물의 수위나 수압등에 대하여 적절히 대응하지 못하게 되는 것이다.That is, when the water level of the water channel 10 rises due to rain or the like, the flow rate increases so that the inflow amount of the contaminant 40 increases, so the removal speed of the contaminant 40 should also proceed rapidly in proportion to the inflow of water. The speed of driving the lifting motor 26 in the control unit 30 is fixed so that it does not properly respond to the water level or water pressure of the water flowing into the waterway 10.

본 발명은 상기와 같은 문제점을 해소하기 위하여 유입수로를 따라 흐르는 물의 수위를 감지하고, 이 감지된 수위레벨에 따라 비례하여 수거기의 운전속도를 자동으로 제어함으로서 우천시와 같이 물의 유입이 많아질 경우 협잡물의 수거 속도를 신속히 하여 수로에 유입된 물의 흐름을 원할하게 할 수 있도록 하는 것을 기술적 과제로 한다.The present invention is to detect the water level of the water flowing along the inflow channel in order to solve the above problems, and by automatically controlling the operating speed of the collector in proportion to the detected water level level when the inflow of water increases, such as during rain The technical task is to speed up the collection of contaminants and to smooth the flow of water into the channel.

상기와 같은 구성으로 이루어진 본 발명의 작용관계를 설명하면 다음과 같다.Referring to the working relationship of the present invention made of the above configuration as follows.

먼저 도 2에서와 같이 수로(10)에 유입되는 물의 수위에 따라 수로(10)의 바닥면에 설치된 수위감지센서(36)의 플로트(38)가 승.하강하게 되며, 이때 플로트(38)의 위치변화에 저항축(39)의 저항값이 변화되며, 이 저항값의 변화로 인하여 전압가변소자(37)의 출력전압이 변화하게 된다.First, as shown in FIG. 2, the float 38 of the water level sensor 36 installed on the bottom surface of the waterway 10 rises and falls according to the water level flowing into the waterway 10. The resistance value of the resistance shaft 39 changes with the position change, and the output voltage of the voltage variable element 37 changes due to the change in the resistance value.

따라서, 수로(10)에 유입된 수위레벨에 따라 변화되는 전압가변소자(37)의 출력전압은 도 3의 콘트롤부(30)인 제어부(31)에 인가되며, 수위감지센서(36)의 출력전압값을 판독하여 그에 비례하도록 인양모터(26)의 구동속도를 여러 단계로 제어하게 된다.Therefore, the output voltage of the voltage variable element 37 that changes according to the water level level introduced into the channel 10 is applied to the control unit 31, which is the control unit 30 of FIG. 3, and the output of the water level sensor 36. The driving speed of the lifting motor 26 is controlled in several stages so as to read the voltage value and proportionate thereto.

즉, 도 4에서와 같이 제어부(31)에서는 수위감지센서(36)로부터 출력되는 전압을 읽어(단계 101)들이고, 이때 읽어들인 전압값으로 현재의 수로(10)에 흐르는 물의 수위를 판독(단계 102)하게 되는 현재수위 판단과정(L1)을 실행하게 된다.That is, as shown in FIG. 4, the control unit 31 reads the voltage output from the water level sensor 36 (step 101), and at this time, reads the water level of the water flowing in the current channel 10 with the read voltage value (step 102 is performed to determine the current water level determination process (L1).

이 후, 상기 현재수위 판단과정(L1)을 통해 판독된 현재수위가 설정된 수위레벨에 해당되는지의 여부 즉, 저수위, 중수위, 고수위인지를 판단(단계 103, 104, 105)하는 수위레벨 판단과정(L2)을 진행하게 된다.Thereafter, the water level determination process determines whether the current water level read through the current water level determination process L1 corresponds to a set water level, that is, whether it is a low water level, a medium water level, or a high water level (steps 103, 104, and 105). (L2) proceeds.

이때 현재의 수위가 저수위로 판단(단계 103)되면 드라이브(32)를 통해 인양모터(26)를 저속으로 구동(단계 106)하게 되며, 현재의 수위가 중수위로 판단(단계 104)되면 드라이브(32)를 통해 인양모터(26)를 중속으로 구동(단계 107)하게 되고, 또한 현재의 수위가 고수위로 판단(단계 105)되면 드라이브(32)를 통해 인양모터(26)를 고속으로 구동(단계 108)하는 모터 구동속도 제어과정(L3)을 실행하게 된다.At this time, if the current water level is determined to be a low water level (step 103), the lifting motor 26 is driven at a low speed through the drive 32 (step 106). If the current water level is determined to be a medium water level (step 104), the drive 32 Drive the lifting motor 26 at a medium speed (step 107), and if the current water level is determined to be a high water level (step 105), the lifting motor 26 is driven at a high speed through the drive 32 (step 108). The motor drive speed control process L3 is executed.

이와 같이 수로(10)의 수위레벨에 따라 인양모터(26)의 구동속도를 여러 단계로 자동 제어함으로서 우천시 수위가 갑자기 불어날 경우 협잡물(40)을 신속히 제거할 수 있게 수로(10)에서의 물의 흐름을 원할하게 할 수 있는 것이며, 본 발명에서는 수위레벨에 따라 저속, 중속, 고속의 3단계로서 인양모터(26)를 제어하도록 하였으나, 수로(10)의 구조나 인양모터(26)의 성능 등을 고려하여 보다 세분화하여 제어할 수 있다.As such, by automatically controlling the driving speed of the lifting motor 26 in several stages according to the water level of the water channel 10, water flows in the water channel 10 so that the contaminants 40 can be quickly removed when the water level suddenly blows in rainy weather. In the present invention, the lifting motor 26 is controlled in three stages of the low speed, the medium speed, and the high speed according to the water level. However, the structure of the water channel 10 and the performance of the lifting motor 26 are controlled. Consideration can be further subdivided and controlled.

이상에서 상술한 바와 같이 본 발명은 수로의 바닥면에 저항축, 전압가변소자, 플로트로 구성된 수위감지센서를 설치하여 유입수로를 따라 흐르는 물의 수위를 감지하고, 이 감지된 수위레벨에 따라 비례하여 인양모터의 운전속도를 자동으로 제어함으로서 우천시와 같이 물의 유입이 많아질 경우 협잡물의 수거 속도를 신속히 하여 수로에 유입된 물의 흐름을 원할하게 할 수 있는 효과가 있는 것이다.As described above, the present invention installs a water level sensor composed of a resistance shaft, a voltage variable element, and a float on the bottom of the water channel to detect the water level flowing along the inflow channel, and proportionally according to the detected water level. By automatically controlling the operating speed of the lifting motor, if the inflow of water increases, such as during rainy weather, the speed of collecting the contaminants can be smoothed, thereby smoothing the flow of water into the waterway.
