Abstract

The present invention relates to a controller of a water level automatic controller used in a septic tank, waste water, sewage, water tank, etc. The controller of a conventional water level automatic controller automatically controls only the main pump and one of the spare pumps manually. Used. When I wanted to control more than one, the pump was controlled by a programmable controller, but the PLC had to be programmed, expensive, and difficult to use. When the main pump is used automatically, it is necessary to switch regularly to use a spare pump to extend the life of the pump. In addition, when the main pump fails, it should be operated with a spare pump to prevent the flooding of the machine room or the electric room.The controller of the conventional water level automatic controller can control the remaining pumps automatically except the pump that is automatically controlled. Since there was no function, the damage caused by this was enormous.

This design eliminates the concept of the main pump and the prep pump, and operates the second stage (two pumps in sequence) and the second stage (two pumps in sequence) in the controller. Alternating start to pump 1 ', three-stage alternating control (starting three pumps sequentially and at the next start, pump 1 pump 2 pump 3, pump 2 pump 3 pump 1, pump 3 pump 1 pump) 2 'alternating start) and a high water level alarm function to enable two or three pumps to start even if the tank has a large amount of water inflow, which prevents a lot of property damage due to water ingress. Multi-stage and alternating controller of the controller.

Description

Multi-stage and Alternating Controllers of Automatic Water Level Controllers {.}

The present invention relates to an automatic controller for level control of septic tanks, wastewater, sewage and water tanks. The present invention aims at improving damage caused by machine room drainage or immersion of septic tank tanks and the use of inefficient pump facilities. By reducing the disadvantages of the controller of the controller, it is possible to reduce the flood damage by driving the pump in multiple stages and alternating.

Since the controller of the conventional water level automatic controller automatically controls only one main pump, the water flows through the main pump only when the main pump is idle or when water breaks down due to water inundation. When the main pump failed, the spare pump had to replace the main pump. The controller of the conventional water level automatic controller can control the remaining spare pump automatically except the main pump which is automatically controlled. Due to the lack of function, damage to the machine room or electric room caused a great loss of property, and there was a disadvantage that the prepump could be left for a long time, causing a breakdown, or the pump could be idled by manual operation. In order to remedy this shortcoming, there is a need to control the pump in multiple stages with one controller and to start the alternating start.

The multi-stage and alternating controllers of the automatic water level controller can perform the multi-stage control function of the pumps in the single controller, the alternating control function of alternating multiple pumps, the alternating control function of alternating the remaining pumps, and the high-level alarm function. It is controller of level control automatic controller.

The present invention relates to a controller of a water level automatic controller that can automatically control the level control. The conventional method was to control only one pump per controller, and there was a method of controlling multiple pumps using a PLC. Since PLC is not a built-in function and user has to input what he wants to control with a program, it is possible to have expert knowledge and it is difficult for the general public to use because of its high price. By changing these closed stages, the multi-stage and alternating controllers of the automatic water level controller have independent functions, so they can control two or three pumps in multiple stages with their own set functions without having to program them. It can be used to distribute load and wear concentrated evenly in the same way. When the main pump is broken, there is an alternating function to control the spare pumps other than the main pump alternately to prevent flooding due to the failed pump and to incorporate a high water level alarm function. Improved the disadvantages of the controller of the conventional water level automatic controller.

As mentioned above, the controller of a conventional water level automatic controller controls a single pump. Therefore, a pump for an emergency such as inundation that may occur in an electric room and a mechanical room such as drainage, sewage, septic tank, etc., in which a pump is installed, is controlled. The load and wear concentration were severe, and it was difficult to cope with the sudden inflow of water with just one pump. In addition, it was cumbersome to switch regularly to operate the preliminary pump. If the Taiwan pump was used intensively without switching the preliminary pump, the service life of the pump was shortened and it had to be replaced. Due to neglect, the pump may not start, the air temperature may be driven by dust or moisture. Overheating may occur, and the pump may run idle due to manual operation. It became a factor of shortening. In addition, the controller of the conventional water level automatic controller can prevent the flooding of the machine room or the electric room when the main pump is broken to prevent the flooding of the machine room or the electric room.The remaining pump can be controlled automatically except the pump that is automatically controlled. There was no function to damage the property.

The multi-stage and alternating controllers of the automatic water level controller have their own independent functions to maximize the pump's efficiency by controlling multiple pumps in multiple stages or alternating with the functions built into the controller without the inconvenience of having to program like a PLC. Unlike the controller of the conventional water level automatic controller that controls only the main pump in an emergency, the preliminary pump can be driven sequentially to prevent physical and property damage due to flooding. By adjusting the water level by driving the remaining pumps, it is possible to prevent the inundation caused by the failed pump. In addition, the manual operation can be used to compensate for the shortcomings of the pump's idling, and the high-level alarm function can be used to notify the flooding damage in advance, and the controller and the controller of the water level controller can be used in two-wire mode without distinction between + and-. The user's convenience and line-saving effect can be expected.

FIG. 1 is a block diagram of two-stage control and two-stage alternating control. When the water level is detected by the sensor detection balls 4a to d installed in the tank 2 such as a septic tank, wastewater, and sewage, the controller 1 controls the controller. By sending a signal to the auto contact configured in the MCC 5, the auto contact starts and stops the pumps 6 to 7 to drive and control the magnet switch in the MCC 5. In the controller 1, the start and stop signals of the pump 1 (6) to the pump 2 (7) are sequentially processed in the second stage control. That is, when started, the sequence continues to the pump 1 (6) -pump 2 (7) and the next signal to the pump 1 (6) -pump (7). In the case of two-stage alternating control, the controller alternates the start signals of pump 1 (6) to pump 2 (7). In other words, when the pump is started, the pump 1 is pump 2, and in the next signal, the pump 2 is pump 1.

FIG. 2 is a block diagram of three-stage alternating control. When the water level is detected by the sensor detection balls 4a to e installed in the tank 2 such as a septic tank, waste water, and sewage, the controller 1 sends a control signal to the MCC ( Sending to the automatic contact configured in 5), this automatic contact starts and stops the pump (6-7-8) to drive and control the magnet switch in the MCC (5). In the controller 1, in the case of three-stage alternating control, the starting sequence is Pump 1 (6) -Pump 2 (7) -Pump 3 (8), and in the following signal, Pump 2 (7) -Pump 3 (8) -Pump 1 ( 6) In the next signal, pump 3 (8) -pump 1 (6) -pump 2 (7) is in order.

<Figure 3> is an electronic circuit diagram of the present invention to explain the general operation according to the drawings, the downtransformer 1 (Trtansformer1) is a unit for supplying power to the AC220Ｖ AC24Ｖ down voltage by rectifying bridge diode (bridge) It is rectified from AC to DC voltage. The rectified DC power is supplied to the circuit through the smoothing capacitor (C1), and the down transformer 2 is the power supplied to the sensor. 4a to e) and the other line is connected to the rectification diodes D1 to D4 via the resistor R4, and the sensor detection balls 4a to e operate according to the level of the septic tank, sewage, wastewater and water tank. The AC power source connected to the sensor sensing balls 4a to e is applied to the rectifying diodes D1 to D4 via a resistor R9, rectified to a DC voltage, and drawn into the zener diodes ZD2 to ZD6. This voltage is applied to the bases of the transistors TR1 to TR5 through the zener diodes ZD2 to ZD6 through the resistors R11 to R15. When the transistors TR1 to TR5 operate, the voltage is applied to the coils of the relays Ry1 to Ry5. The relay (Ry1 to Ry5) is turned on and the relay contact is turned on to operate the pump 6-7-8. IC4017 (Decker counter) has a resistance (R11) through Zener diode (ZD2) when the sensor detection ball (4-a) is turned on through the rectifier diode (D1 to D4) through the rectifier (D9 to D4). After passing through transistor TR1, drive relay Ry1 and when A contact Ry1-A 'of relay Ry1 is ON, the + voltage is made into pulse by electrolytic capacitor C3 and resistor R21. The resistor R2 is clocked to the input pin of the IC4017 and transmitted to the IC4017 output terminal to turn on / off sequentially when the light emitting diodes LED7, LED8, and LED9 are turned on / off by the sensor detection balls 4a to e. This output is operated by relays (RyA, RyB-OFF)-(RyA ON)-(RyB ON) in order, so the pump (6-7-8) ) Change the operation order of operation relays (Ry2, Ry3, Ry3).

As described above, the present invention can be used in order to alternate the two-stage control, two pumps that can control two pumps with one controller, deviating from the conventional method of controlling only one pump from the controller of the water level automatic controller. Two-stage alternating control, three-stage alternating control which can control three pumps alternately, except controller which has failed according to the condition of pump The property damage caused by pump failure can be prevented. It is possible to use the efficiency of the pump to the maximum than the method of driving the closed pump, that is, the main pump and the preliminary pump, and the preliminary pump through the switching device, and adjust the water level by using the remaining pump except the failed pump. It has the function of alternating function and can use the desired function with one controller without the need of several controllers, and it is easy to install because the multi-purpose function is built in the controller by reinforcing the disadvantages of economical and programmable PLC method. By using +,-without distinction, it is possible to inform the flood damage in advance by incorporating line saving effect and high level alarm function.
