Description

Wireless automatic water level control {APPARATUS FOR WIRELESS AUTOMATION WATER LEVEL CONTROL}

The present invention relates to a wireless automatic water level control device, and more particularly, such as constant water, leachate or wastewater containing groundwater (hereinafter referred to as raw water) When the distance for transporting the pipe from the point where it exists to the desired storage means is far (10s to several kilometers), the pressure sensing means mounted on one side of the pipe detects the water pressure and automatically stores the amount of raw water. By determining and controlling, the present invention relates to a wireless automatic level control device that enables efficient level adjustment.

In general, the water level adjusting device for collecting raw water as a storage means is installed in a predetermined area, the water intake well (1) and the pumping water is installed in the intake well (1) in the schematic diagram of FIG. Means 2, a pipe 3 for transferring the raw water drained from the pumping means 2 to a predetermined position, and the predetermined water is installed at the end of the pipe 3 to store the raw water discharged through the pipe (3) Determination and operation of the storage means 5 of the capacity, the water level sensing means 6 mounted on the inside or one side of the storage means 5 for sensing the water level, and the signal detected from the water level sensing means 6 to control the control signal. It includes a controller (7) for outputting a and a wire (4) having a predetermined length embedded or processed in order to transfer the control signal output from the controller (7) to the pumping means (2).

Conventional water level control device having such a configuration is to drain the raw water through the pipe (3) from the water intake well (1) to the storage means (5). The drained raw water is stored in the storage means 50, when the predetermined amount is filled, the water level detecting means 6 detects the amount of raw water and converts it into an electrical signal, and the converted electrical signal is input to the controller 7 In response to the input signal, the controller 7 controls the driving of the pumping means 2 through the wire 4. That is, the pumping means 2 of the intake well 1 receives the raw water and then the pipe 3 If the storage capacity of the storage means (5) is filled by the set amount when draining to the storage means (50) through the controller, the controller (7) stops the driving of the pumping means (2) so that no more water is taken in. It is.

Thus, in the conventional case, in order to drain the raw water pumped from the pumping means through the pipe, the pipe is necessarily required, and the pipe is connected to the processing state or embedded in the ground. However, since the wiring for transmitting the control signal from the controller to the pumping means has to be separately processed or buried, double connection work is required, and the processed or buried wire may be disconnected, shorted or leaked by external influences or conditions. If the controller could not transmit the normal control signal from the controller to the pumping means, the raw water stored in the storage means overflowed. In addition, if the pumping means is always operated in an operating state, the durability of the pumping means is reduced, which has the disadvantage of shortening the life, and the electric wire as well as the loss of leakage or leakage of electric power due to disconnection, short circuit or leakage, electric shock Problems that could cause accidents were also inherent. In addition, since the separate wires are wired, the cost of installing and maintaining the water level regulator was also increased.

The present invention has been made in view of the above-mentioned problems, and a wireless automatic water level control device capable of automatically controlling the pumping means wirelessly without wiring a wire between a pumping means for taking raw water and a storage means for storing raw water. The purpose is to provide.

In addition, an object of the present invention is to install a pressure sensing means on one side of the pipe connected between the pumping means and the storage means to automatically control the pumping means in the on (On) or off (Off) state by the water pressure in the pipe It is.

Alternatively, the relay contact is turned off.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a wireless automatic level control apparatus according to the present invention.

The controller 10 controls various instruments configured in the water extraction well 12, and is composed of electric or electronic circuits. In particular, the controller 10 has a function of controlling the pumping means 18 by determining the signal detected from the pressure sensing means 13. That is, the controller 10 controls the operation of the pumping means 18 by turning on or off the AC power source AC110-220V applied to the pumping means 18.

The water intake well 12 discharges the raw water pumped from the pumping means 18 through the pipe 19, and the pressure sensing means 13, the water meter 14, and the control valve 15 are connected to the connected pipe 19. And a check valve 16 or the like.

The pressure detecting means 13 detects the water pressure formed in the pipe 19 and outputs a detection signal to the controller 10 when the pressure exceeds the set pressure. In addition, the pressure sensing means 13 detects instantaneous water pressure when the sudden water pressure is sensed at a constant pressure and the pumping means 18 is driven, and the pressure sensing means 13 detects water flow. Sensors can be applied. In the case of the water flow sensor, the water flow in the pipe 19 is turned off when the flow of water is stopped, and then turned on when water flows, or turned on when the flow of water is stopped, and turned off when water flows. Can be switched to a state. In particular, when the water flow sensor is applied, it is preferable to have a plurality of contacts whose state is switched according to the speed of water flow.

The sewage water meter 14 displays the volume of water pumped from the pumping means 18, detects and displays the amount of raw water, and preferably an analog or digital form is applied.

The control valve 15 is designed to control the amount of raw water supplied along the pipe 19, and opens and closes the flow of raw water. In addition, the check valve 16 sets the direction of the raw water flowing along the pipe 19, and is for preventing the back flow of raw water.

The pumping means 18 pumps the raw water in the ground or in the ground where the raw water is stored. Preferably, the pumping means 18 may be installed in the water intake well 12 of the ground depending on the geographic situation or the positional repayment. It is preferable that the pumping means 18 use a motor pump, and as long as the pumping means 18 can pump raw water, it can apply anything.

The pipe 19 connected from the water intake well 12 extends to a place for storing the raw water, and the pipe 19 is installed on the processing or the ground surface, and is preferably embedded in the ground.

The storage means 20 is to store raw water, and has a predetermined volume capable of storing raw water in a storage tank or a water well. Raw water stored in the storage means 20 is discharged or pumped to another storage means through a separate pipe or water pipe.

One end of the pipe 19, that is, the end of the pipe 19 provided to the storage means 20 is equipped with opening and closing means 22 for opening and closing the flow of raw water, the opening and closing means 22 opens and closes the pipe 19 The opening and closing opening 23 and the sub-portion 24 for driving the opening and closing opening 23 are included. That is, when the water level of the raw water stored in the storage means 20 rises, the buoy 240 floating by the buoyancy on the surface of the raw water simultaneously rises, and the opening and closing port 23 coupled to the buoy 24 is the raw water of the pipe 19. When the discharge port is blocked, and the raw water exits through a separate pipe or the like, the sub-ball 24 is lowered again and the opening-closing port 23 is opened.

The operation of the pumping means 18 of the present invention and the control state of the controller 10 and the pressure sensing of the pressure sensing means 13 will be described.

First, Figure 3 is a graph showing the relationship between the time and pressure at the time of restarting the pumping means according to the present invention, a predetermined amount in the pipe 19 in the relationship between the water pressure (P) and time (t) in the pipe 19 When the pumping means 18 is driven while the water is filled, the predetermined pressure is maintained for the first time interval (for example, about 2 seconds), and the pumping means 18 drives the pumped raw water. At this point, the water pressure rises rapidly to a predetermined water pressure (for example, about 5-7 kgf / cm ² ), continues for a predetermined time (for example, about 2-6 seconds) during this rising period, and then the discharge port of the pipe 19 When the raw water is discharged, the pressure drops to normal water pressure again.

That is, when the discharge port of the pipe 19 is closed or raw water does not flow in the pipe 19, the water pressure in the pipe 19 is maintained at a constant pressure, and the pumping means 18 is activated to supply raw water to the pipe 19. When the water pressure is applied while supplying water, the pressure rises, and when the water is supplied while the raw water is filled in the pipe 19, the constant pressure is maintained in the pipe 19 again. The time and pressure to be started may vary depending on the length of the pipe 19.

On the other hand, if the operation state of the wireless automatic water level control device of the present invention with reference to the electrical circuit diagram of Figure 4, first switching the main switch (M / S) to the on state to drive the pumping means 18, AC The power source AC is supplied to the electric circuit through the main switch M / S.

At this time, the supplied AC power source AC is applied to the timer T through the contact SW of the pressure sensing means 13, and the timer T counts for a predetermined time. The time to be counted is, for example, about 1 to 3 hours, and the storage means 20 counts a time suitable or proportional to the capacity. This can be set variably according to the storage capacity of the storage means 20, and acts as a factor for determining a predetermined time for discharge of raw water from the storage means 20.

Therefore, the timer T switches the state by the AC power applied while the count is made for a set time, and in the switched state, the timer contact t is turned on from the off state, and the timer contact ( When t) is on, the relay RL is also switched from off to on. Therefore, while the relay contact rl connected to one end of the magnetic coil MC is switched from the off state to the on state, the pumping means 18 is driven by driving of the magnetic coil MC.

Raw water pumped by the pumping means 18 is discharged and stored in the storage means 20 via the pipe 19. At this time, as the raw water stored in the storage means 20 is filled with the float 24 in the storage means 20 with the raw water by the buoyancy, due to the rise of the float 24 is the opening and closing port 23 is a pipe ( The discharge port of 19) is closed.

When the raw water is filled by the amount set in the storage means 20, the opening and closing means 22 provided at the end of the pipe 19 is closed, the water pressure in the pipe 19 rises. At this time, the pressure sensing means 13 detects the pressure in the pipe 19 and the state is switched when the pressure exceeds the set pressure, and the contact point SW of the pressure sensing means 13 is switched from the on state to the off state and then again. An instantaneous contact change occurs in the on state, whereby the timer T is reset.

Therefore, the AC power source AC applied to the magnetic coil MC is turned off at the same time as the timer T is driven and the relay contact RL is turned off when the relay RL is turned off. The shut-off state causes the pumping means 18 to stop.

Therefore, the raw water supplied to the pipe 19 by the stop of the pumping means 18 is no longer supplied to maintain the off state.

On the other hand, the timer T is counted for a set time after the reset, and after the set time, the timer contact t is switched again, the magnetic coil (MC) is operated by the drive of the relay (RL) pumping The means 18 is activated to allow pumping.

This operation is repeatedly performed, and as long as the main switch M / S is not turned off, the operation is continuously performed.

As described above, the present invention senses the water pressure in the pipe by the pressure sensing means and controls the pumping means on or off at every set time of the timer, so that the raw water discharged from the pumping means is supplied to the storage means of the opening and closing means of the pipe. Operation, that is, pumping means continuously pumping the raw water at short time intervals by continuously raising and lowering the float according to the level of the raw water, can solve the problem that the pumping means can be applied to extend the life of the pumping means, Raw water can prevent the problem of overflowing the storage means, and by controlling the pumping means wirelessly has the effect of significantly reducing the cost required for installation and maintenance.
