Abstract

PURPOSE: A residual fuel amount measuring device for a domestic heating oil-boiler is provided to precisely and conveniently check the residual amount of fuel in a room by a liter unit by transmitting a signal of a detected residual amount to a display element via a wall socket of a power supply. CONSTITUTION: A residual fuel amount measuring device for a domestic heating oil-boiler includes a float(1) and a weight(2) for moving vertically in opposite directions to each other according to a fuel level in a fuel tank(7), and a roller and a rotation sensing plate to be engaged to each other to rotate in association with each other according to a motion of a plane belt(4) connected to the float and the weight, a control plate for receiving sine and cosine signals output from the rotation sensing plate for converting a current height of residual fuel to a data, and a display element for displaying the converted residual fuel amount digitally by a liter unit according to the data output from the control plate via a wall socket mounted in a room and connected to a power source.

Description

Boiler fuel remainder measuring system

The invention consists of some mechanical parts but the control device is entirely electronic

Control is the mainstream, and the up and down movement of the bobbin and weight rotates the rollers.

Accordingly, from the signal of the infrared sensor (sine wave, cosine wave) coming from the rotation sensing plate

Detect the increase or decrease of fuel according to the shanghai of the fuel level and raise and lower the rotation pulse

The value of this counter will be the height of any oil, and this value is used to

Calculate the product of width and height and convert it to liters, the actual amount of oil.

This data value is loaded on the high frequency carrier and supplied to the outlet power supply side.

Outlet power is used for power and communication to the tank side controller.

In a room, you can insert the receiver into a wall outlet and read it on the receiver.

I have been using oil boilers for decades until now

Missing or measuring the actual amount of oil currently being injected and consumed

As a result of worrying about losing hourly consumption, etc.,

All parts were able to obtain good results through actual experiments.

The oil tank in your home's oil boiler is almost always in the dark corner of your home.

In order to check the oil level, you have to go to a narrow and dark place.

Transparent hoses intended to be checked are faded and difficult to see. That's why

It's very difficult to cut it, so it's rough to use it

It is common. In addition, each time the question is whether the amount of oil actually supplied matches the actual order quantity

It is also. In the era of high oil prices,

There are many homes that reduce boiler uptime by installing them.

If you know how much is actually being consumed per hour, per day, per week, etc.

It will be possible to effectively control the operating time of the boiler.

1: Assembly completion degree

Assembled completeness on the tank side, just plug the power cord into the outlet

Fig. 2: Working principle and configuration

The weight of the bure in the air must be heavier than the weight, and the bure is a hollow cylinder.

Brother. The share of bure should be less than the share of fuel. So that only fuel (petroleum, diesel,

This is because it can float on boiler oil. In addition, the flat belt is a strip of steel

Is the same as the material of the ruler).

Interlock to prevent slipping

Fig. 3: Cover and control board

Caba is used for the protection of the device.

All measurement work is done only by supplying power

Fig. 4: Roller and rotation sensing unit

As the roller rotates forward or reverse as the fuel increases or decreases,

Also rotating, through the aperture, the infrared light from the infrared transmitter reaches the receiver. The receiver consists of a pair and is out of position so that 90 degrees of phase difference is achieved.

Sine and Cosine Waves Are Generated

Fig. 5: Tank side mounting part and machining part

This fuel tank is part of the installation part to facilitate processing when installed in the existing tank.

The opening of the pen and weight is made into a large circle. Big hole processing called HOLE SAW

Because it can be easily machined

6: Remaining amount display device

Easy to see room Plug into an outlet and read the readings on the display Check it.

The button switch displays the actual value of the tank and resets the current quantity to zero.

To measure the amount of change.

Representation: Related block diagram of the overall operation

The oil tanks for heating oil boilers in all homes are mainly rectangular pillars.

So if we know the actual oil height, we can calculate the volume of oil

The amount is known. Using this principle, the oil level in the oil tank

Continuously detects and converts the actual value from the microchip of the control panel

It is transmitted through the household power supply line. This operation repeats quickly in real time.

It is then received through the display via the power outlet in the room and the amount of oil

Can be viewed in liters with digital indicators.

1. When fuel is injected, the remnant of the heating fuel of the boiler can be checked in liters in the room.

It can be seen.

2. You do not have to go and check the oil tank in the dark and cramped place.

As long as a person is in the room, the amount of oil can be known continuously.

3. When oil is injected, order quantity can be compared with actual amount injected.

4. The oil consumption can be known and the oil can be used efficiently to maximize the oil saving.

Can be.

5. When installing, do not connect the cable from the oil tank to the room with the wires.

There is no hassle of wiring the signal lines by transmitting and receiving.

6. Existing level hoses are damaged by rats' teeth and exposed to the outside.

Therefore, it is easy to be crushed by material change caused by sunlight, and there is considerable

There is a hum.

Claims (2)

The construction and enlarged view of the fuel residual quantity measuring device shown in FIG. 1 (assembly completion) are shown in FIGS . 2, 3, 4, and 5 It is shown in detail in Fig. 1 and the fuel reduction and injection Depending on the fuel level as the fuel increases, the burrs and weights interact with each other This will move along the level, as shown in Figure 2 (Operating Principle and Schematic). Figure 4 shows the rollers and the rotation sensing plate according to the movement of the knitting and weights. To interlock and rotate. Then, the signals (sine wave and cosine wave) detected by the rotating plate are controlled in FIG. 3 (cover and control board). Subsequent operation of the control board is performed by the counter of the pulse coder. By operating the same principle as the UP DOWN counter, Convert the height to arbitrary data. Obtain the volume of the rectangular column by converting the data of the remaining fuel level into a metric unit. If you find the volume by the formula (horizontal x vertical x height), This calculation is done automatically in the control panel. DATA converted into liters is modulated with high frequency in the control board of FIG. The cord is sent to an outlet throughout the house. The transmitted data is transferred from the control panel of the fuel level indicator which is plugged into the outlet of the room. The signal is detected and shaped and displayed on a digital display. The display device is equipped with a pushbutton so that the absolute value of the remaining fuel in the tank (the fuel remaining Quantity and relative value (change amount + or-). In addition, oil tanks are different in size from home to home, so it is easy to operate with a program Is programmed by. Add to the boiler temperature controller in conjunction with the boiler manufacturer using the results of paragraph 1 By attaching the remaining indicator, the data is sent through the signal line from the boiler to the temperature controller. Display the remaining fuel level by sending. Then using existing signal and power lines There is no need to install additional lines.
