Description

Automatic operation control device for rubber dam using solar energy {APPARATUS FOR CONTROL OPERATION AUTOMATIC OF RUBBER DAM USING SOLAR ENERGY}

The present invention, for example, relates to a rubber dam that secures a low amount by shrinking and expanding the rubber beam by the injection and discharge of air in accordance with the desired low amount of water among the various dams (DAM) installed in the river, river or valley, etc. More specifically, solar energy is used as a power source for rubber dams in mountain walls or in rivers or rivers or valleys where terrain is difficult to supply and facilities are difficult to operate, and the rubber dams are automatically operated without operator intervention. The present invention relates to an automatic driving control device for a rubber dam using energy.

In general, many rubber dams, such as folding or ups and downs, have been developed as banks of agricultural / industrial intakes, water intakes, and freshwater inflows. It is attracting great attention as an embankment bank because it is easy to secure an effective low water quantity, install and install it easily, and control the height of the rubber beam by air pressure according to the desired water level.

Most of these collapsible or inflatable rubber dams are designed to be filled with air for the expansion and standing of the rubber beams, and the air generating the fixing device and the compressed air for fixing the rubber beams to the riverbed concrete and the embankment. A motor and a blower of a supply device, piping equipment for supplying or discharging the generated compressed air into a rubber beam, and a water level sensor for sensing the water level, in particular, automatically or manually operating the rubber dam. As an example of an unmanned operation device to be known, it is known by the Republic of Korea Utility Model Registration No. 107602 (name: unmanned operation device of a undulating rubber dam).

Figure 1 shows one of the unmanned operation device of such a undulating rubber dam described in the Republic of Korea Utility Model Registration No. 107602, R, S, T three-phase at the front end of the air pipe 11 of the rubber beam 10 In the installation of the motor 60 and the blower 61 which are driven by receiving AC power in sequence, a plurality of exhaust pipes 42 are formed in the middle of the air pipe 11 to form a solenoid valve 40 in each exhaust pipe. , (41) and the motor valve 43 is installed, respectively, the pressure gauge 50 is installed on the side of each wire electrically connected to the control unit 30, the ultrasonic water level sensor 20 is installed on one side of the reservoir The blower 61 and each of the valves 40, 41, 43 can be operated by the control unit 30 installed in the operation room on one side of the embankment by the level detection information sent out.

In addition, a check valve 61a is installed in the air pipe 11 in front of the blower 61 to prevent air in the rubber beam 10 from leaking toward the blower 61 when the blower 61 stops driving.

When the unmanned operation device of the undulating rubber dam configured as described above automatically switches the operation panel installed in the operation room, the control unit 30 closes all the valves 40, 41, 43 of the exhaust pipe 42. When the motor 60 is driven after opening the check valve 61a, air is injected into the rubber beam 10 by the blower 61 driven by the motor 60 so that the rubber beam 10 stands. .

At this time, the air pressure in the rubber beam 10 is grasped by the pressure gauge 50 and the data of the pressure gauge immediately indicates the height of the rubber beam 10. Therefore, when the control unit 30 installed in the operation chamber is determined by the pressure gauge 50 to determine that the dam has reached a predetermined height, the control unit 30 cuts off the power supplied to the motor 60 to stop the driving.

The water level of the dam is detected by the ultrasonic level sensor 20, and the detected water level data is sent to the control unit 30 of the operation room. In the controller 30, when the water level rises above the reference constant level compared to the reference sewage level and the reference constant value, which is analyzed and set, the water flows over the rubber beam 10 and the dam is not preferable for safety. The solenoid valve 40 is opened while the power is supplied to the solenoid valve 40 by the control of 30. Accordingly, the air filled in the rubber beam 10 is air pipe 11 and the solenoid valve 40 opened. The rubber beam 10 is covered by being exhausted through the exhaust pipe 42 through. When the rubber beam 10 is coated, fresh water is drained through the rubber beam 10 in a large amount. At this time, when the fresh water level is adjusted from the dangerous level to the normal level, the solenoid valve 40 is closed by the control of the controller 30, so that no further exhaust action occurs.

In addition, when the water level detected by the ultrasonic water level sensor 20 reaches the set reference sewer level, the controller 30 needs to raise the water level of the dam to the reference level, so all the exhaust valves are closed and only the check valve 61a is opened. In this state, power is supplied to the motor 60 of the blower 61 to operate the blower 61.

When air is filled in the rubber beam 10 through the air pipe 11 and the check valve 61a by the operation of the blower 61, the air pressure in the rubber beam 10 gradually increases, whereby the rubber beam (10) gradually stands up. At this time, the pressure gauge 50 detects the air pressure in the rubber beam 10 and provides it to the controller 30. The controller 30 senses the ups and downs of the rubber beam 10 with the data on the air pressure detected by the pressure gauge 50 and stops the operation by cutting off the power supplied to the motor 60 when the set height is reached. .

In addition, in order to quickly exhaust the air filled in the rubber beam 10 to temporarily drain a large amount of water, the motor valve 43 may be opened, and the solenoid valve 41 may be used in case of inspection or emergency. have.

In addition, when the air pressure in the rubber beam 10 becomes a prescribed value and the driving of the blower 61 described above is stopped, the controller 30 closes the check valve 61a provided at the front end of the blower 61 to open the rubber beam 10. ) To prevent the air pressure in the air to leak toward the blower (61).

In the state where the above-mentioned rubber dam is automatically operated, when a power failure occurs, power is supplied from the uninterruptible power supply to maintain the automatic operation state.

However, the unmanned operation device of the undulating rubber dam according to the Utility Model Registration No. 107602 described above is installed in a large river or river with good terrain conditions, and it is easy to install transmission towers and power lines for supplying electric power from KEPCO. The problem does not occur in a large dam, but when a small dam is to be installed in a mountain wall or a river, river or valley where terrain conditions are not very good, the electric power for the small dam in the KEPCO is first used. As a result of the difficulty of supplying a power source to each of the small rubber dams by installing a supply facility, that is, a transmission tower, and then drawing a power line, there is a lot of constraints. It is pointed out that the problem is impossible.

In addition, even if small rubber dams are installed in narrow rivers, rivers, and valleys as needed, they must use electricity supplied from KEPCO as a power source, resulting in more power consumption than securing low water. There is a problem that the effectiveness falls.

Accordingly, an object of the present invention is to provide a power source of the small dams when supplying a power source by installing small dams, respectively, in rivers, rivers, valleys, or the like, where mountain terrain or terrain conditions are very poor. It is to provide an automatic operation control device for rubber dams using solar energy to operate with natural energy such as solar energy to secure a low amount of water. The automatic operation control device for rubber dams collects solar energy and converts it into electrical energy. Photovoltaic unit for charging the battery, an inverter for converting the charged electrical energy into AC power supply to the rubber dam as a power source, and a constant voltage unit for providing the operating voltage to the control unit of the rubber dam by dropping the charged electrical energy Is achieved.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

Figure 2 is a block diagram showing an embodiment provided in the description of the automatic operation control device of the rubber dam using solar energy according to the present invention.

As shown in FIG. 2, in the rubber dam automatic driving control apparatus using solar energy according to the present embodiment, one end of the air pipe 11 is connected to the rubber beam 10, and the motor 60 is connected to the front end of the air pipe 11. And a blower 61 driven by the pipe, and a plurality of exhaust pipes are formed in the middle of the air pipe 11 to provide the solenoid valve 40, the manual valve 41, and the motor valve 43 to each of the exhaust pipes. After installing the pressure gauge 50 for measuring the air pressure of the rubber beam 10 on the side thereof, the air in the rubber beam 10 is generated by the air pressure of the blower 61 according to the driving of the motor 60. In a conventional rubber dam for compressing and injecting the rubber beam 10 to stand or doubly operate according to the water level measured by the ultrasonic water level sensor 20, it is installed perpendicular to the ground of the rubber dam installation site to generate solar energy. Condenses and collects the concentrated solar energy in multiple solar fields The photovoltaic unit 100 converts and outputs the DC power through the G module 100a, a storage battery 120 that accumulates and supplies the DC power input from the photovoltaic unit 100, and the storage battery 120 ) And a direct current prevention unit 110 formed of a backflow prevention diode that prevents the DC power supplied from the reverse flow to the photovoltaic unit 100 and the DC voltage supplied from the storage battery 120 to drop the direct current. The rubber dam according to the constant voltage unit 150 for outputting the output voltage after shaping the voltage to a constant level of a constant level, and the normalized voltage and operating according to the water level detected by the ultrasonic level sensor 20 and the air pressure measured by the pressure gauge 50.

Phase AC voltage As a power source of the emitter 60 consists of a supply and cut off the power switch 140 to.

The automatic operation control device of the rubber dam using the solar energy according to the present invention made as described above will be described in more detail below.

First, the photovoltaic unit 100, which is installed perpendicular to the ground of the rubber dam installation site and has a small capacity of a plurality of solar cell modules 100a, collects solar energy and converts it into direct current power. The DC power output from the photovoltaic unit 100 is continuously accumulated in the storage battery 120 through the backflow prevention unit 110. The output of the solar cell module (100a) is determined according to the capacity of the motor 60 to be described later, and the backflow prevention unit 110 is the direct current power accumulated in the storage battery 120 is the solar power generation unit 100 It is composed of a backflow prevention diode to prevent backflow.

Subsequently, the DC voltage accumulated in the storage battery 120 is lowered in the constant voltage unit 150, and then, is shaped to a constant voltage at a constant level, and is supplied to the controller 30, and the three-phase AC voltage is supplied from the inverter 130. Is converted to and supplied to the power switching unit 140.

In such a state, when the manager operates the operation panel (not shown in the drawing) to automatically set the operation of the rubber dam, the controller 30 sets the voltage supplied from the constant voltage unit 150 as the operating voltage, and the exhaust pipe 42. Close the solenoid valve 40, the manual valve 41, and the motor valve 43 installed in the valve, and open the check valve 61a installed in the air pipe 11, and then the power switching unit to stand the rubber beam 10. 140 is controlled.

The power switching unit 140 supplies a three-phase AC voltage supplied from the inverter 130 to the motor 60 under the control of the control unit 30 to operate the blower 61, whereby air is blown from the blower 61. Is generated.

Air generated in the blower 61 is supplied to the rubber beam 10 through the check valve 61a of the air pipe 11 so that the rubber beam 10 stands up gradually. At this time, the control unit 30 measures the air pressure in the rubber beam 10 from the pressure gauge 50 installed in the air pipe (11). When the measured air pressure reaches the air pressure set value set in the operation panel, the air is supplied by cutting off the three-phase AC voltage of the inverter 130 supplied to the motor 60 through the power switching unit 140. By stopping the, the rubber beam 10 is eventually raised to a desired height to ensure a low amount of water.

Thereafter, when the rubber beam 10 stands up by the height of the set value and the water level is changed in the state of securing a low amount of water, the height of the rubber beam 10 should also be changed.

To this end, the ultrasonic water level sensor 20 detects the level of the fresh water stored by the rubber beam 10, and provides the detected water level data to the controller 30.

When the water level is higher than the reference constant level in comparison with the water level data detected by the ultrasonic water level sensor 20 and the preset reference sewer level and the reference constant value, the controller 30 overflows the water over the rubber beam 10 and dams. Since this is not preferable in terms of safety, the rubber beam 10 is gradually inclined by opening the solenoid valve 40.

When the rubber beam 10 is inclined, the fresh water flows downstream through the rubber beam 10, thereby closing the solenoid valve 40 when the fresh water level is adjusted from the dangerous level to the normal level. By stopping the doppling state of the rubber beam 10, the safety level is always maintained.

As such, the controller 30 continuously outputs the photovoltaic unit 100 and automatically operates the rubber dam by the voltage input through the storage battery 120 and the constant voltage unit 150, and the motor 60 operates in the sun. The rubber beam 10 stands by the three-phase AC voltage output from the photovoltaic unit 100 and input through the storage battery 120, the inverter 130, and the power switching unit 140 to secure a low amount of water at a desired level. Will be.

On the other hand, as a comparative example, there is a difficulty in using electricity supplied from KEPCO as a power source when attempting to install a small dam in a conventional technique, that is, a mountain wall or a river, a river or a valley having poor terrain conditions. Alternatively, it can be seen that the present invention operates the power source of the small dams using natural energy such as solar energy, which is easy to install a power supply source.

In this result, according to the present invention, small rubber dams are operated by using natural energy such as solar energy, so that power supply from thermal and hydro power plants is not necessary, and small rubber dams and power supply sources can be installed. There is an easy advantage.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.

According to the automatic operation control device of the rubber dam using the solar energy of the present invention, which is clear from the above description, when the dam is installed in a mountain wall or a river, a river or a valley having poor terrain conditions, By using only natural energy, it is environmentally friendly and economical, and it is easier to install small rubber dams and a power supply source for powering them.
