The present invention relates to a liquid amount display device that is completely enclosed in a gas cylinder or a tank so that anyone can easily know the amount of liquid contained therein, and more specifically, a gas in a liquefied state filled in the tank, that is, The present invention relates to a device for displaying the residual amount remaining in the tank according to the state of using a liquid amount such as propane gas or butane gas which is used in general households or automobiles.

A device for displaying the amount of liquid in the tank from the outside is already disclosed in Japanese Patent Application No. 50-6262 and Korean Utility Model Publication No. 480 (Notification No. 81-78), both of which are long connecting rods. The float is installed in the tank so that the float can be operated in accordance with the increase and decrease of the amount of liquid, so that the amount of liquid contained in the tank can be determined. In the case of being able to lie down in the lateral direction, it operates to display the existence of liquefied gas accurately until the amount of liquefied gas in it is used, but the gas tank, which is used in general households, is used in automobiles. Unlike the gas tank, it is designed to be used vertically and long, so that the liquefied gas in the tank If only one float falls below the working distance, the float will not run all the way, so the meter attached to the outside of the gas tank is clearly marked as having no trailing liquefied gas even though the liquefied gas is in the gas tank. have.

That is, the above-described conventional liquefied gas display device is attached by attaching a float to the connecting rod. As it is designed to be operated under low pressure, gas tanks intended to stand vertically for general household use are totally useless.

In addition, both of the prior art described above, because the bevel gear is fixed to the connecting rod connecting the float due to the operation of the float to rotate the axis extending to the bevel gear, thereby reducing the amount of liquefied gas in the gas tank Since both are mechanical structures, such as bevel gears, they can be detected. There is a disadvantage of being shortened.

The present invention is to solve the above drawbacks, firstly to be used not only in the liquefied gas storage tank containers that are used in the horizontal direction lying on the vehicle, but also to be used in propane gas storage containers used long standing in normal households, second The furnace is not a mechanical configuration such as a bevel gear as in the prior art, so that all operations are operated by a circuit configuration to be described later, so that there is no risk of malfunction, and it is designed to be used almost permanently.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In a known liquid level display device which displays an amount of liquefied gas stored in a tank, a magnet 3 is built in the outer circumference of a normal long rod 1 made of metal. A plurality of disc-shaped floats 2 are imaged. It is regrettable to be able to move, and on both sides of the float 2, the rods 1 having the storage plate 6 and the interference plate 7 provided with a predetermined gap 4 so that a predetermined space 5 is formed. a resistor (R ₁₎ a sweet, in a conventional electric jangbong (1) on the outer periphery ... (R ₉ ) and lead switch (RSW ₁ ). After inserting the circuit (C) formed by connecting the RSW ₁₀ in parallel, the fixed rod is fixed with a known epoxy resin (F), and the long rod in which each of the parallel connected resistors (R ₁ ) and the lead switch (RSW ₁ ) are electric This float 2 is formed so that it may correspond to each float 2 in which the magnet 3 resonated in the outer periphery of (1). Resistor (R ₁ ) (R ₉ ) and lead switch (RSW ₁ ). (RSW ₁₀ ) is operated separately.

In the drawings, reference numerals 8 and 9 denote the upper and lower parts of the gas storage tank, and reference numeral 10 denotes a fixture for fixing the liquid level display device of the present invention to the upper portion 8 of the tank. ) Is a cover to cover the fixture (10), (12) a screw to fix the cover (11) to the fixture (10), (13) washer, (15) rubber packing, (14) (14 ') ) Is an electric line drawn out from the circuit (C) in Jangbong (1), (16) is a notch groove for drawing out the electric line (14, 14 ') to the outside, (17) is an electron meter, (18) Instructions of the electronic meter 17, 19 is a battery, 21 is a switch 22 is a screw hole.

On the other hand, the total length of the long rod (1) can be arbitrarily changed according to the length of the gas storage tank, the float (2) is upper. The space portion 5 between the unloaded restraint plate 7 and the sustain plate 6 is formed by the lead switch RSW ₁ by the magnet 3 of the float 2. What is necessary is just to be able to turn ON and OFF the RSW ₁₀ , and to form a predetermined narrow gap 4 between the float 2 and the float 2 is sensitive to magnets. The distance between the lead switch and the lead switch is shortened so as to be prevented from being operated by the influence of the magnets 3 of the respective floats 2 arranged in close proximity to each other.

The material of the above-mentioned float 2 may be any light material which is lower than the specific gravity of the gas in the liquid state.

As described above, when the operation and effect of the present invention are described, the liquid level display device 7 of the present invention is mounted in the gas storage tank as shown in FIG. 2, and when the liquefied gas is injected into the tank, In accordance with the increase in the water level, each float 2 is suspended from the float 2 held up to the hold plate 6 positioned close to the bottom 9 of the gas tank. Each lead switch RSW ₁ fixed in the rod 2 by an epoxy resin. (RSW ₁₀ ) is located at the center of the. This float 2... Each lead switch (RSW ₁ ). To be located at the center of RSW ₁₀ is as shown in FIG. 2, each lead switch RSW ₁ ... Each interference plate 7 welded to the outer circumference of the long rod 1 so as to be located directly above the RSW ₁₀ . Is achieved by

Thus float (2)…. Each lead switch (RSW ₁ ). … An interference plate 7 at the central position of RSW ₁₀ . Is positioned as indicated by the dashed-dotted line in FIG. 2, the respective lead switches RSW ₁ ... RSW ₁₀ denotes each float 2... Magnetized by a magnet (3) embedded therein, and are all turned on as indicated by a dashed line in FIG. 3, where the rated current flowing from the battery (19) through the electrical conductor (14) is turned on Lead switch (RSW ₁ ) (RSW ₁₀ ) flows in the direction of the arrow B and is introduced into the electromagnet of the anode of the electron meter 17 through the electric conductor 14 '. At this time, the instructions of the electron meter 17 in the zero scale are indicated. (18) moves to the point indicated by the dashed line and indicates that there is only a layer of liquefied gas in the gas tank.

In this case, the resistance R ₁ . The value of (R ₉ ) is the lead switch (RSW ₁ ). Since they are connected in parallel with each of RSW ₁₀ , the state is zero. That is, the lead switch RSW ₁ ... When (RSW ₁₀ ) is turned on, the resistors (R ₁ )... (R ₉ ) The value is zero, so the lead switch (RSW ₁ ). It has no effect on the current flowing through (RSW ₁₀ ).

On the other hand, suppose that only the float 2 stored in the gas tank and floating on the uppermost part of the long rod 1 due to the use of a small amount of liquefied gas was moved to the original holding plate 6, where the lead switch RSW ₁₀ ) is turned off because it is out of the influence range of the magnetization force of the magnet 3 of the float 2, and at this time, the lead switch (RSW ₁ ). Since the lead switch RSW ₁₀ is also turned off, the current flowing from the RSW ₉ does not flow to the lead switch RSW ₁₀ , but flows in the direction of the arrow D as shown in FIG. 3 and passes through the resistor R ₉ . Is introduced into the electron meter 17 through the electrical conductor 14 '.

At this time, the amount of current introduced into the electron meter 17 is a small amount of current flows by the resistance (R ₉ ) and (R) value applied to the total current flowing from the battery 19, the amount of the reduced current Instructions at the position of the pool indicated by the dashed line are down.

If the lead switch RSW ₁ is almost in the on position due to the magnetization force of the magnet 3 of the float 2 using almost the liquefied gas in the pank, the current flowing from the battery 19 is the lead switch RSW _2. )… It does not flow toward (RSW ₁₀ ) but flows in the direction of the arrow (E), so that the resistance (R ₁ ). Via (R ₉ ), it is introduced into the electron meter 17 through the electric conductor 14 '.

At this time, the amount of current introduced into the electron meter 17 is equal to the resistance R ₁ . (R ₉ ) and a small amount as the action of the resistance (R) value is introduced, so the guide 18 of the electronic meter 17 is moved back to the position by the decreasing amount to display the amount of liquefied gas in the tank at that time give. On the contrary, when the liquefied gas is only layered in the tank, the operation is reversed.

If the amount of liquefied gas in the tank is increased or decreased in this manner, then the float (2)... ... Each lead switch (RSW ₁ ). (RSW ₁₀ ) came. To turn off each lead switch (RSW ₁ ). Resistor R ₁ connected in parallel with RSW ₁₀ . The current flow is changed according to the value of (R ₉ ) so that the amount of liquefied gas in the tank is displayed.

The resistor R is connected so as to match the amount of current flowing from the battery 19 with the capacity of the electron meter 17.

As described above, the present invention, unlike the conventional liquefied gas quantity display device, enters into the gas tank to display the liquefied gas amount, so that the exact amount of liquefied gas can be displayed by using the gas tank in the home as well as in a vehicle. In addition, unlike conventional mechanical type, there is no fear of breakdown because it displays the amount of liquefied gas according to the change of resistance value by the operation of the lead switch by the operation of a large number of reluctant floats in the long rod. There is a good practicality that can be used almost permanently.
