Wireless automatic control apparatus for maintaining predetermined water level

The present invention, in the automatic water level control device for controlling the water pump to maintain a constant level of water in the water tank in the distance, by placing a transmitter in the water tank for storing water to detect and transmit the water level state by the water level measurement sensor, The control unit for controlling the supply of water relates to a wireless water level automatic control apparatus configured to have a receiving unit to supply the water supply while adjusting the water level by wirelessly received data.

In general, in order to use seawater or groundwater far away from a water source, a water supply device in which a water pump is installed in a water source to supply water through a pipe to a remote user generally uses water even in a power outage or a pipe replacement. The water tank is supposed to store a certain level of water. To this end, the submersible pump for supplying water to the water tank is provided with a control device for controlling to operate properly according to the water usage.

Conventional control device for controlling the operation of the submersible pump uses a water pressure sensor to control the supply of water to the water tank by detecting the valve opening and operating the pump when the pressure of the pipe falls below a predetermined value. In addition, the pump start time and standby time can be set by timers according to the water usage, so that the water tank level can be adjusted appropriately. However, when the leak occurs due to breakage of the pipe, the control device recognizes that the water pressure sensor incorrectly recognizes it as a valve opening, and operates the pump, which wears the valve and increases the water pressure in the pipe, thus reducing the water level of the water tank only a small amount. Even if the pump is operated, there is a problem of repeating the operation and stop of the pump each time the water level drops.

In order to improve this, conventionally, the automatic water supply device of FIG. 1 has been developed. 1 is a schematic configuration diagram of a general automatic water supply device, an underwater pump (2) for sucking up and pulling water inside a well casing (1) installed in a water source, and connected to one side of the underwater pump (2) 2) a submersible motor (3) for driving, a strainer (4) connected between the submersible pump (2) and the submersible motor (3), the submersible pump (2) is connected to the other side of the submersible pump (2) Pumping pipe (5) for passing the water discharged from is provided, the cable (6) for supplying power to the submersible motor (3), the water level measuring tube (7) for measuring the water level, the low water level measuring sensor (8) and The high level measuring sensor 9 is further provided. In the pumping pipe 5, an air valve 10 for discharging gas and a pressure gauge 11 for measuring pressure are staked out and connected to the pipe 13 by a union 12. Pipe 13 has a flow rate sensor 14 for switching the contact by sensing the flow of water, check valve 15 for preventing backwater, stop valve 16 for opening and closing the pipe, water meter 17 for measuring the amount of water used Are installed at regular intervals. At the distal end of the pipe 13 in the water tank 18 is provided a valve 19 for opening and closing the pipe, the valve 19 is connected to the floater 20 to the water level in the water tank 18 Due to the change, the floater 20 moves up and down to open and close the pipe. The flow rate sensor 14 and the check valve 15 freezes the water remaining in the pipe during the winter season by allowing the water remaining in the pipe to flow backward when the water tank 18 is at full water level and the valve 19 is closed. It is connected to the reverse circulation line 21 to prevent the freeze-in caused. And connected to the control device 22 for controlling the operation of the submersible pump (2) and the submersible motor (3), the control device 22 and the flow rate sensor 14 to maintain a constant water level in the water tank (18) A water level automatic control device 23 is further provided to control the start and standby time of the submersible pump 2 and the submersible motor 3.

The switch 36 is further provided.

In such a configuration, when the underwater motor 3 is driven through the contact point ③ of the third timer 34 during the time (about 10 seconds) when the water passes through the flow rate sensor 14 at the first power-on, By detecting the flow, the flow rate sensor 14 is switched to the contact point ② to continue to start the underwater motor 3 while the water is flowing (until the valve 19 is closed). At this time, when the water tank 18 closes the valve 19 from the full water level, the flow rate sensor 14 switches back to the contact point ③ to stop the operation of the submersible motor 3 and at the same time the second timer ( 33) to wait for the pump to start.

When the set time of the second timer 33 (time when the water in the water tank is depleted) expires and the contact 6 is switched, the first timer 31 and the relay 32 operate to perform a predetermined time (from underwater). When the water motor 3 is started for a time until the water passes through the flow sensor 14, after which the flow sensor 14 is switched to the contact (②) to close the valve (19) Until the underwater motor (3) is operated. When the water tank is full again and the valve 19 is closed, the flow rate sensor 14 is switched to the contact point ③ to operate the second timer 33 to wait for the underwater motor 3 to operate. As described above, the submersible motor 3 repeatedly performs the operation of water supply and air by the automatic water level automatic control device 23.
