Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a non-powered drive control apparatus and a control method thereof,

More particularly, the present invention relates to a non-power-source drive control apparatus for level measurement, and more particularly, to a buoyant ball control apparatus for controlling the level of a buoyancy ball by converting a linear motion of a buoyant ball into a circular motion, The present invention relates to a non-power source drive control device for level measurement capable of continuously measuring a water level by continuously rotating the water level by controlling rotation by its own weight and stably maintaining the water level by controlling the water level, and a control method thereof.

The water level controller is a key device that automatically controls the operation of the motor pump when draining or watering the tank facility.

Drainage and water supply facilities utilize ultrasonic water gauge and water level sensor as a basic signal to repeatedly control water level by process, to operate equipment and to accumulate data.

It is very important to know the exact water level at all times. It is the core task of the manager to adjust the water level according to the change of the main process or the flow rate.

Therefore, it takes a lot of time and money to secure the reliability, maintenance, and stability of the water level control system.

However, the water level regulator currently operating is exposed to a lot of problems due to the poor environment and does not take advantage of the automatic operation.

The facilities currently in operation are as follows.

First, Patent Registration No. 10-0386419 entitled "Water level sensing device" refers to a water level sensing device that detects a change in inductance in a coil when a floating sensor in a cylindrical water level sensing rod wound around a water tank is wound up and down according to a water level The present invention relates to a water level sensing device for detecting a water level, wherein a floater having an iron core or a ferrite core is constructed so as to float in water and is inserted into a cylindrical water level sensing rod wound with two coils at the top and bottom, The lower coil is operated when the floating coil is operated and the floating coil is lowered when the floating coil is lowered, and the current level can be accurately sensed by the control circuit.

In addition, the registered utility model No. 20-0421962 "ultrasonic water level sensor" relates to an ultrasonic water level sensor that senses the liquid level in various storage spaces. In a main configuration, when a strong sound wave is transmitted , This sound wave is reflected back to the liquid surface and senses the distance reflected through the receiver.

A weak signal received through a receiving unit is firstly amplified through a first amplifying unit and further amplified through a second amplifying unit and then compared with a reference signal through a comparing unit and then a stable signal is sent to a microcomputer control unit, In the compensator, the change of the ambient temperature of the sensor is input to the microcomputer control unit, so that it is possible to measure a more accurate distance by reducing the deviation of the distance according to the temperature change.

In the power section, the power supply required by the microcomputer control section is stably supplied. Also, the output signal sent from the microcomputer control section is converted into the current signal through the current section and then sent to the power section. In the power section, The water level controller that receives this signal senses the water level to enable various control functions such as pump control, high / low alarm, and present value display.

The display unit displays the current water level so that it can be easily seen even on the spot where the storage tank is installed. In the selection switch unit, the height setting and the dead zone can be arbitrarily set according to the size of the storage space.

Further, the present invention is characterized in that the central monitoring room computer at a remote location can also know the current water level through the communication unit, and various setting values that can be set by the selection switch unit can also be set.

When the liquid storage tank and the inside of the storage chamber are low, the sensor of the present invention is small and light in weight, so that the installation is easy, and the indicator for detecting the current water level is installed in the sensor, so that a liquid storage tank It is a non-contact type that does not make contact with the substance to be controlled and the sensor is in contact with each other. Therefore, it can be used for various chemicals, high viscosity materials and powders. We have proposed a complementary sensor.

However, the water level control apparatus according to the related art has problems such as corrosion caused by corrosive gas generated by sewage, such as a sewage treatment plant, damage of a water level measuring apparatus caused by sewage treatment plants and various floats flowing into a rainwater pumping station, A problem has arisen.

In addition, there is a problem that installation is not easy since there are restrictions on the installation environment (installation angle, water surface wave) at the time of installation of the level gauge.

In addition, due to the use of electrical signals by sensors installed in the water to measure the water level, breakage of electronic circuits due to lightning and short circuits frequently occurs in the summer, which is a problem, and repairing in the field is not easy, There are many problems.

In addition, there is a problem that the detection rod for detecting the level of water level must be reinstalled, and the electronic level controller requires a remote controller for correcting the setting program by using the converter, which is not easy to control in the field.

In addition, the water level sensor, the timer, the PLC, and the various controllers do not operate when the power supply system for the automatic operation of the facility in the water treatment system fails to control power due to the power failure and the short circuit.

In addition, the present applicant has proposed Patent Registration No. 10-1448435, " leveling device and its measuring method "

"Level gauge and its measuring method" proposed by the present applicant as described above. The vertical vertical movement of the buoyancy ball is changed from a wire drum to a rotary motion and is returned by a lower roller of a weight weight.

However, in the related art, there is a possibility that the twist phenomenon of the returned wire and the buoyancy ball or the foreign matter is caught by the lower roller, and the operation is not smooth.

Of course, the weight 70 of the level measuring unit 60 may be provided outside by the user's choice.

The coupling relationship and the operating relationship of the non-power source drive control device 10 for level measurement according to the present invention will be described in detail as follows.

As shown in Figs. 1 to 3, the buoyancy member 22 of the lifting section 20 is inserted into the storage tank 12 or the collecting tank 12.

The buoyancy member 22 and the fixed wire 24 are wound on the upper roller 42 of the conversion unit 40 located above the storage tank 12 or the collecting tank 12.

A decelerating member 62 of the level measuring unit 60 is disposed on the upper portion of the gear member 44 provided on the same axis as the upper roller 42 so as to rotate with reduced rotation.

A drum member 64 is provided on one side of the reduction member 42 so as to be reduced in speed by the reduction member 62.

A weight 70 is provided on the other side of the deceleration member 62 to control the rotation of the deceleration member 62.

Further, sensors 82 and 84 of the control unit 80 capable of measuring the rotation of the drum member 64 are further provided.

That is, the non-power-source drive control device for a measuring apparatus of the present invention can be easily installed by simply inserting the buoyancy member of the ascending and descending portion into the collecting and rainwater pumping station and easily lift the buoyancy member of the ascending / It is easy to maintain and easy to use because of its simple structure.

Also, since the durability of the rising and falling portions is excellent, it can be used for a long time.

Further, since the lifting and lowering portion is supported by the weight of the buoyancy member, the flow due to water and foreign matter is less, and error in level measurement by foreign matter can be minimized.

Further, since the structure of the conversion unit and the level measuring unit is simple and is located outside, maintenance and repair are easy and installation and repair can be done easily by anyone.

In addition, since the conversion part and the water level measuring part are driven by the non-power source due to the weight of the weight part of the ascending and descending part and the weight of the weight, there is no need for a separate power source, so that it can be used easily in case of emergency such as energy saving and power failure. It can be prevented in advance.

The non-power source drive control device for level measurement, which is simply coupled to the storage tank or the house collection as described above, is controlled by the non-power source drive control method for level measurement as shown in FIG.

The weight of the buoyancy member 22 of the ascending and descending part 20 and the weight 70 of the level measuring part 60 are mutually associated with each other and the position of the weight member 70 And a horizontal step (S10) for maintaining the fixed position.

That is, it is determined whether or not the position of the weight 70 is appropriately positioned in accordance with the state where the buoyancy member 22 inserted in the storage tank 12 or the collecting chamber 12 is positioned, and the buoyancy member 22 and the weight 70 The position is to adjust the level to be horizontal.

For example, as shown in FIG. 3, the level of the water level in the storage tank 12 or the water collecting tank 12 is set at an appropriate level so that the weight member 22 and the weight 70 are horizontal,

When the water level is low, the buoyancy member 22 is positioned at the bottom, the weight 70 is positioned at the top,

When the water level is high, the buoyancy member 22 is positioned at the upper portion and the weight 22 is positioned at the lower portion.

In addition, the horizontal step S10 may be easily adapted to the field according to the length of the wire 24 and the state in which the wire 24 is wound on the upper roller 42, so that the desired horizontal level is obtained by the user.

After the horizontal step S10 is performed as described above, a linear motion step S12 is performed in which the buoyancy member 22 makes up / down linear motion according to the level of the storage tank or the collecting tank 12.

That is, when the water level of the storage tank or the water collection tank 12 is changed according to the amount of water flowing into and discharged from the storage tank 12 or the water collection tank 12, the buoyancy member 22 is lifted and lowered along the water level by buoyancy, Is changed.

As described above, the linear motion step S12 forms the circular motion converting step S14 in which the upper roller and the gear member of the converting unit are rotated.

That is, the wire 24 is loosened or pulled depending on the position of the buoyancy member 22 so that the upper roller 42 of the conversion section 40 can be rotated by the wire 24 wound on the upper roller 42 .

This is because the weights 70 of the water level measuring part 60 in the state where the upper roller 42 and the gear member 44 of the converting part 40 can be rotated by the pulling or loosening of the wire 24 The speed reducing member 62 and the gear member 44 of the converting portion 40 are rotated to rotate the converting portion 40. [

3, when the water level is low in the storage tank 12 or the collecting tank 12, the buoyancy member 22 is positioned at the lower portion to pull the wire, so that the weight 70 is rotated to be positioned at the upper portion, 22 to control the rotation of the converting unit 40. The rotation of the speed reducing member 62 is controlled by the rotation of the speed reducing member 62,

When the water level is high, the buoyancy member 22 is positioned at the upper portion and the wire 24 is loosened. As a result, the weight 70 is rotated to its lower position by its own weight rotation, (24) and controls the rotation of the conversion section (40).

The drum member 64 is rotated by the weight of the weight 70 and the speed reducing member 62 of the level measuring unit 60 during the rotation of the converting unit 40 by the circular motion converting step S14 as described above, And the water level is measured by the drum member 64 (S16).

That is, in the circular motion conversion step S14, the drum member 64 is rotated by the reduced weight rotation of the weight 70 of the level measuring unit 60 and the decelerating member 62, and the decelerated rotation of the drum member 64 The water level is measured by measuring the rotational position of the water level measuring section 69 of the belt member 68 provided on the drum member 64 according to the ascending and descending heights of the buoyancy member 22. [

The reason for this is that in the level measurement step S16, the ascending and descending part 20 makes a linear movement by the buoyancy by the level of the storage tank 12 or the collecting tank 12,

The converting unit 40 and the speed reducing member 62 are controlled by the speed reduction ratio and the weight of the weight 70 according to the position of the buoyancy member 22 by the linear motion,

The rotation of the decelerating member 62 causes the drum member 44 to rotate and the accurate level measurement can be achieved by the rotation of the drum member 64 depending on the position of the buoyancy member 22. [

The sensor 82 or 84 of the control unit 80 senses the level measuring period 69 of the belt member 68 provided on the drum member 64 by the rotation of the drum member 64, It is possible to precisely measure the level of collecting water.

Of course, at the time of power failure, the water level can be measured by discriminating the level measuring section 69 of the belt member 68 with the naked eye.

As shown in FIG. 4, for example, the water level measuring section 69 of the first strip member 68a is divided to measure the maximum water level H during the water level measurement.

The level measuring section 69 of the second belt member 68b is divided into the highest and lowest danger levels HH and LL to achieve an alarm function.

The level measuring section 69 of the third belt member 68c is divided so that the lowest level L can be measured.

3, the drum member 64 of the level measuring unit 60 is rotated in accordance with the rising and falling of the buoyancy member 22 according to the water level,

The water level measuring section 69 of the first to third belt members 68a, 68b and 68c is measured by the sensor 82 of the control unit 80 or the naked eye by the rotation of the drum member 64, Which can control the level of the storage tank and the collection tank.

The depth measurement sensor 84 of the control unit 80 and the rotational angle of the drum member 64 with the naked eye are precisely measured to separately measure the depth of the storage tank 12 or the water collection tank 12, Can be accurately measured.

The control unit 80 or the control step S18 for manually controlling the pump 16 of the sewage treatment plant or the rainwater pump station according to the level of the storage tank 12 or the collection tank 12 measured by the measuring step S16 Erum is preferable.

That is, the belt member 68 provided in the drum member 64 of the level control driving control apparatus 10 driven by the non-power source and the control unit 80 or the sewage treatment plant according to the water level measured by the naked eye The pump 16 of the rainwater pump station is automatically or manually driven to properly maintain the level of the storage tank or the collection tank.

This is because if the measurement intervals 69 of the first to third belt members 68a, 68b and 68c are not measured as shown in Fig. 4, the water level is maintained at an appropriate level,

Since the water level is high when only the measurement section 49 of the first belt member 68a is measured, the pump is driven and the first and second belt members 68a and 68b are driven simultaneously or after the first belt member 68a is measured If the measurement period 69 of the second belt member 68b is also measured, the water level is at a dangerous level, so that more pumps can be driven and a danger warning level can be obtained.

When the measuring section 69 of the third belt member 68c is measured, the pump 86 which has been driven to the lowest water level is stopped, and the second belt member and the third belt member 68b, If the measurement period 69 of the second belt member 68b is measured immediately after the third belt member 68c is measured, it is possible to warn the user that the water level is at a dangerous level, so that the user can take necessary measures.

Needless to say, the position of the band member 68 can be changed by the user, and the reference zero point can be easily changed by rotating only the band member 68 according to the use environment.

For example, in the case of the drainage control system, when the first level member 48a is detected, the water level is high. Therefore, the pump is driven to drain the buoyancy member 22, When the third belt member 68c is detected, the pump stops and the drainage is terminated.

If the water level rises by the inflow water from the outside, the first strip member 68a is sensed by the buoyancy of the buoyancy member 22, and if the pump 16 is operated but the water level is not lowered by the inflow water, 68b) are detected and operate alarms and a large number of pumps to get out of the danger level and achieve stable water level.

Therefore, the second belt member 68b provides an alarm function that can alleviate the malfunction of the submersible motor or alert the system low water level based on the malfunction of the control unit 80 or the maximum and minimum level due to inactivity of the control unit 80, thereby achieving the stability of the system.

Needless to say, the positions and measurement procedures of the belt members 68a, 68b, and 68c may be easily changed by the user's selection, and they are included in the technical idea of the present invention.

The non-power-source drive control device for level measurement according to the present invention and its control method have an excellent effect that the structure of the apparatus is simple, and the installation is easy, and the construction and trouble-repair are quick and convenient to manage.

In addition, even when the power failure or the control circuit fails, the power supply is driven by the non-power supply to provide the control value, and the water level according to the water level change is detected, thereby achieving the link operation of the manual control.

In addition, anyone can always adjust the water level according to the change of the water level in real time at any time.

In addition, there is an effect that the time for adjusting the water level and repairing the trouble can be minimized.

In addition, it is possible to reduce the cost and size of the electric control panel by operating without a separate electronic converter, and the system is simple and easy to integrate with the peripheral system.

In addition, there is an effect that the durability of the component material is excellent, the risk of corrosion or breakage is small, and the electric parts are easily purchased using the ready-made products and the price is low,
