The water intake well 20 includes pumping means 22 for supplying raw water through a water pipe by driving power supplied to the raw water, and the intake well 20 is a location or a point where water can be intake, that is, a reservoir or It is installed in a collecting basin to take water or to take water from a basement excavated to a predetermined depth.

The controller 10 for controlling the pumping means 22 of the water intake 20 is configured, the controller 10 includes an electrical or electronic circuit for the control. In particular, the controller 10 preferably includes a microcomputer (or microprocessor) for controlling input and output signals. In addition, the controller 20 is configured with a circuit for receiving, converting, and amplifying a radio signal. The power line 21 is connected so that the controller 20 can supply or cut off power for controlling the driving of the pumping means 22.

The first detecting means 14 is a pneumatic pipe 16 for converting the pressure of the raw water by the atmospheric pressure in accordance with the water level of the raw water, and a pneumatic pressure for converting the magnitude of the air pressure formed in the pneumatic pipe 16 into an electrical signal It consists of a sensor 15. The pneumatic pipe 16 is filled with air (Air, air) 17, the air 17 is compressed and expanded in accordance with the pressure of the raw water to apply a predetermined pressure to the pneumatic sensor 15, pure Instead of air 17, it is possible to enclose a gas (Gas) that can deliver a precise compression and expansion rate.

The storage means 40 has a predetermined capacity to store the raw water supplied from the water pipe 24, and easy storage such as a water tank for supplying the stored raw water is applied.

In addition, the second sensing means 34 for sensing the water level or the amount of raw water stored in the storage means 40, the second sensing means 34 has the same configuration as the first sensing means 14 And a pneumatic pipe 36 for converting the pressure of raw water by atmospheric pressure into air pressure according to the level of raw water stored in the storage means 40, and the magnitude of the air pressure formed in the pneumatic pipe 36 as an electrical signal. It consists of a pneumatic sensor 35 to convert. The pneumatic pipe (36) is filled with air (Air, air) 37, the air 37 is compressed and expanded in accordance with the pressure of the raw water to apply a predetermined pressure to the pneumatic sensor 35, pure Instead of air 37, it is possible to enclose a gas (Gas) that can deliver a precise compression and expansion rate.

The first sensing means 14 is mounted when the raw water in the water intake well 20 is at the natural water level, and the pumping means 22 supplies the raw water with the initial pressure (for example, when the initial value is set to 0). Pumped water is set so that the raw water falls down to a fixed level so as to detect a value that changes to a negative value, and the second detecting means 34 stores the raw water in the storage means 40 when the water level is low. Equipped with an initial pressure (for example, when the initial value is set to 0), the raw water stored in the storage means 40 can be detected to change to a positive value. It is desirable to set so that. However, depending on the installation conditions, the first sensing means 14 and the second sensing means 34 can detect the first sensing means 14 from the natural water level to the fixed water level with respect to the initial set value. It is possible to have a change value of, and the second sensing means 34 may detect a high level to a low level so as to have a negative (−) conversion value.

In addition, the signal sensed by the second sensing means 34 is converted and amplified into a radio signal in the transmitter 30 and then transmitted wirelessly through the transmitting antenna 32, and the transmitted radio signal is transmitted to the controller 10. Received at the receiving antenna 12 of the pumping means 22 to be able to control. In addition, in the present invention, it is preferable to wirelessly transmit the signal sensed by the storage means 40 to the controller 10, but the water extraction well 20 and the storage means 40 are located at a short distance or according to the needs of the user. That is, the signal line 42 may be transmitted and received. The first and second sensing means 14, 34 are preferably cylindrical, but may use a tube of polygonal shape, the lower part is perforated, and the upper part is sealed by a pneumatic sensor.

In addition, the controller 10 has a first display unit for receiving water from the first sensing means 14 and displaying it in the form of water pressure (for example, kgf / cm ² ) in order to display the water level of the raw water in the water intake 20 as a pressure. 13 and a second display unit 15 which is received from the second sensing means 34 and displayed in the form of water pressure to display the water level in the storage means 40 by pressure. The first and second display units 13 and 15 may be displayed in the form of water level (for example, cm or m) rather than in the form of pressure.

On the other hand, Figure 4 is another embodiment showing a state configured to detect the level of the storage means, the third sensing means 50 of the same type as the second sensing means 34 outside the storage means 40 Mounted in, the pneumatic pipe 52 is connected by the connecting pipe 54 from the lower end of the storage means 40 to be able to detect the pressure of the stored water. This is preferably applied when it is not easy to install the sensing means in the storage means 40.

The automatic water level adjusting device of the present invention configured as described above allows the pumping means 22 of the water intake well 20 to be controlled by a program set in the controller 10, and the controller 10 can receive a radio signal. Or the device is built-in.

First, the raw water in the water intake 20 in the water intake 20 of the present invention is a natural water level is naturally filled, and a fixed water level is formed by the normal intake when the raw water is intake by the pumping means (22). In other words, the fixed water level is the limit water level at which the pumping means 22 can normally take water from the water intake well 20.

In the water intake well 20, the pumping means 22 for pumping raw water, and the water supply pipe 24 is connected when supplying the raw water withdrawn from the pumping means 22, the first sensing means for detecting the water level of the raw water ( 14) is included. The first detecting means 14 is installed when the raw water is in the natural water level in the intake well 20, and the initial value is set in the installed state. That is, since the air 17 is filled in the pneumatic pipe 16 of the first sensing means 14 so that the air 17 does not leak to the outside, the raw water in the intake well 20 is at atmospheric pressure (at natural water level). a) and the pressure by the level of the raw water pushes up the air 17 of the pneumatic pipe 16. At this time, the pneumatic pressure of the air formed in the pneumatic tube 16 extends to the pneumatic sensor 15 of the upper, the pneumatic sensor 15 detects the pressure formed in the pneumatic tube 16 as an electrical signal The conversion is output to the controller 10. Accordingly, the controller 10 sets the pneumatic pressure of the pneumatic pipe 16 formed by the natural water level in the water intake well 20 to an initial value, and converts this value into a pressure value so that it is displayed on the first display unit 13. do.

In this way, the air in the pneumatic pipe 16 is raised by position a by the atmospheric pressure and the water level at the natural water level, and the pneumatic pressure in the pneumatic pipe 16 decreases as the water level decreases as the pumping means 22 pumps the raw water. Since the value detected by the pneumatic sensor 15 also falls apart, the first display unit 13 continues to display the detected pressure through the controller 10.

On the other hand, if the raw water falls to a fixed level when the raw water filled with the water intake well 20 is not greater than the amount of raw water being pumped due to the continuous pumping of the pumping means 22, the atmospheric pressure (b) in the water well 20 And the air formed in the pneumatic pipe 16 by the water pressure formed by the water level is relatively expanded and descends to the b position, so the pneumatic sensor 15 detects the current pressure value and outputs it to the controller 10. The controller 10 prevents the pumping means 22 from being driven without intake of raw water by cutting off the power supplied to the pumping means 22 through the power line 21 so that no further pumping is performed. will be. In this case, the controller 10 converts the electrical signal input from the pneumatic sensor 15 into a pressure value and displays the same through the first display unit 13.

As described above, the first detection means 14 of the water intake well 20 detects the initial value 0 set at the natural water level, and continuously detects a negative value until the fixed water level. This may be arbitrarily set to a positive value at the request of the user.

In addition, in Figure 3, the storage means 40 is discharged from the raw water supplied from the upper connected water pipe 24, the raw water is to be stored in the storage means 40, the storage means 40 also the second sensing means ( 34) to control the amount of raw water withdrawn.

That is, after installing the second detecting means 34 in a state in which raw water is not withdrawn to the storage means 40, the air pressure of the air formed in the pneumatic pipe 36 is sensed by the second pneumatic sensor 35, thereby transmitting the transmitter 30. In the modulation and amplification process, and the processed data is transmitted to the receiving antenna 12 of the remote controller 10 via the transmitting antenna 32 as a radio signal. At this time, the controller 10 amplifies and demodulates the radio signal received from the receiving antenna 12 so as to output and display the pressure on the water level of the storage means to the second display unit 15.

As such, when the installation of the second sensing means 34 in the storage means 40 is completed, the raw water supplied from the water supply pipe 24 is stored, and the stored raw water is filled up to the high water level set in the storage means 40. At this time, a value corresponding to the controller 10 is set so that the raw water supplied from the water supply pipe 24 may be blocked by the user's request. That is, when the raw water rises to the storage means 40, the air in the pneumatic pipe 36 is compressed due to the pressure due to the atmospheric pressure (a) and the water level of the raw water, so it is detected by the second pneumatic sensor 35 and converted into an electrical signal. After that, the controller 30 transmits the data to the controller 10 via the transmitter 30 and the transmitting antenna 32. The controller 10 compares the received value with a previously set value through the power line 21 when the value is greater than or equal to the set value. The power supplied to the pumping means 22 is cut off to stop the driving of the pumping means 22 so that no more raw water is supplied through the water supply pipe 24. The controller 10 displays the information about the water level in the storage means 40 as the pressure value through the second display unit 15. The air pressure formed in the pneumatic pipe 36 when the raw water is in the high water level in the storage means 40 rises to the a position by the atmospheric pressure a and the water pressure.

In addition, when the raw water stored in the storage means 40 is discharged through the discharge pipe (not shown) connected separately, the water level of the raw water in the storage means 40 is lowered. At this time, when the raw water stored in the storage means 40 at the request of the user reaches a predetermined water level, that is, the low water level, the pneumatic pressure formed in the pneumatic pipe 36 is controlled by the atmospheric pressure b and the water pressure in the pneumatic pipe 36. The air pressure is lowered to the b position, and the air pressure is sensed by the second air pressure sensor 35 and transmitted to the controller 10 via the transmitter 30, the transmitting antenna 32, and the receiving antenna, and the controller ( 10) sets the received signal to the low water level state and then displays it on the second display unit 15 and at the same time supplies power to the pumping means 22 through the power line 21 so that the pumping means 22 is driven. To make the water intake.

The second detecting means 34 installed in the storage means 40 basically detects an initial value (0) set at a low water level or a low water level, and continuously detects a positive value until a high water level. . This may be arbitrarily set to a negative value at the request of the user.

In addition, the storage means 40 may be installed outside the storage means 40 as shown in FIG. 5 without installing the second sensing means 34 in the storage means 40. In this case, After connecting the storage means 40 and the sensing means 50 to the connecting pipe 54, the hydraulic pressure generated in the storage means 40 is sensed by pneumatic pressure and transmitted to the controller 10 to control the pumping means 22. It is to be able to control the water level in the storage means (40). Even in this case, the water level in the storage means 40 is formed by the atmospheric pressure a and b, the position of the air 53 in the pneumatic pipe 52 to the position of a and b, respectively, and such pneumatic pressure is detected by the pneumatic sensor 51 By transmitting to the controller 10, the pumping means 22 can be controlled by the controller 10.

On the other hand, the data on the water level change of the storage means 40 is wirelessly transmitted and received by the transmitter 30, the transmitting antenna 32 and the receiving antenna 12, etc. In this case, the water well 20 and the storage means In the case of a remote distance (eg, more than 1 km) of the predetermined distance of 40, but less than a distance of a predetermined distance, for example, less than 1 km, the signal line 42 between the transmitter 30 and the controller 10 in the form of a wire. Connect to enable sending and receiving signals.

As described above, the automatic water level control device of the present invention is for detecting and controlling the water level change of the water extraction well and the remote storage means, and is not limited only to the above-described embodiments and ranges and can be easily modified, replaced, and changed by those skilled in the art.
