[Technical field to which the device belongs]

 The present invention relates to a liquid level display device in a container, more specifically, a device for easily displaying the liquid level in an arbitrary portable container such as a drum can by the liquid level display by atmospheric pressure without using power or other energy. It is about.

[0002]

[Prior art]

 Conventionally, various level gauges have been used to know the amount of liquid in an arbitrary container. Typical examples are as follows. (A) A means for making a hole on the outside of the container, installing a liquid column gauge here, and visually measuring the liquid level in the container. This method is the simplest method generally used.It has a simple structure, but it requires drilling and mounting work for each container, and it can be used for any unfixed drum can or other optional work. It is time-consuming, inconvenient, and inconvenient to be used for the container. (B) Means using a float or the like that floats on the liquid surface in the container. This means includes a method of mechanically transmitting the position of the float and capturing the position, and a method of capturing the position of the float by an electrical signal. FIG. 4 shows an example in which the height 3 of the liquid surface of the liquid 2 in the container 1 is measured by the combination of the float 4, the wire 5, the pulley 6, the weight 7, the pointer 8 and the scale 9. However, any of these methods becomes unusable if the parts deteriorate, and the structure is complicated, which makes mounting work troublesome and the price is expensive. (C) A means for optically searching with a liquid level sensor. The liquid surface level fiber unit (FU-95) manufactured by KEYENCE Co., Ltd. optically searches the liquid level in the transparent pipe with a liquid level sensor. This method enables highly accurate liquid level detection at a fixed position, but many sensors must be attached to detect the liquid level that fluctuates in an arbitrary container each time and to know the amount of liquid in the container. It is necessary, the equipment is complicated and unsuitable. In addition, since this device is a sensor, it cannot detect the liquid level by itself, and it is always necessary to combine it with other devices, which increases the cost.

[0003]

[Problems to be solved by the device]

 As described above, various types of conventional liquid level display devices in containers have been used, but it takes a lot of time and labor to attach the device to each container, and the price Is also expensive. In addition, since it is necessary to attach a device fixed inside and outside the container in advance, there is a suitable liquid level display device in a stationary container, but any existing portable device such as a drum can is used. In order to measure the liquid level in the container individually at any time, it is necessary to process the inside and outside of the container and attach a liquid level indicator each time, which is not practical. In view of the above, it is an object of the present invention to provide a simple liquid level display device capable of easily, individually, and inexpensively measuring the liquid level in an arbitrary portable container.

[0004]

[Means for Solving the Problems]

 It is a liquid level display device that can be attached to and detached from the portable container by measuring the liquid level of the liquid stored in the portable container by displaying the liquid level at atmospheric pressure without using power or other energy. It is composed of a series of pipe parts and a frame part surrounding the main part of the pipe parts, and a liquid column meter of U-shaped pipe is formed in the pipe parts, and one end of which is inserted into the liquid in the portable container. The other end is in communication with the atmosphere, and a scale for reading the height of the liquid level in the liquid column and a liquid level indicator rod are attached to the U-shaped pipe in parallel with the U-shaped pipe. A liquid level indicator that can slide up and down is attached to this indicator rod, and the height of the liquid level can be read by moving the liquid level indicator according to the movement of the liquid level in the liquid column. It is configured to be able to.

FIG. 3 is a schematic diagram showing the main configuration and operation of the simple liquid level display device 10.

FIG. 3 shows the height of the liquid surface of a liquid 60 (the liquid surface of which is shown by the broken line) contained in an arbitrary portable container 50 such as a drum (the outline of which is shown by the broken line). The simple liquid level display device 10 attached to the portable container 50 for measuring is shown. As shown in the figure, the simple liquid level display device 10 of the present invention comprises a series of pipe parts 20 and a frame part 40 (shown by a broken line) surrounding a main part of the pipe parts 20. A U-shaped liquid column meter 22 is formed in the pipe portion 20, one end 21 of which is the container side and is inserted into the liquid 60 in the portable container 50, and the other end 23 is of which the atmosphere side is connected to the atmosphere. . This simple liquid level display device 10 is an independent device separated from the portable container 50, and when measuring the liquid amount in a certain container, it may be attached to the container each time to perform the measurement. it can. A scale 30 for reading the height of the liquid level in the liquid column and a liquid level indicator rod 31 are attached in parallel to the U-shaped pipe 22 on the liquid column gauge 22 of the U-shaped column. A plurality of abacus ball-shaped pieces that can slide down are attached as the liquid level indicator 32. By moving the pieces 32 in accordance with the movement of the liquid level in the liquid column, the height of the liquid level can be easily adjusted. You can read it.

When measuring the amount of the liquid 60 stored in the portable container 50, the frame portion 40 of the simple liquid level display device 10 is fixed to the outside of the container 50, and the pipe portion 20 of the container 50 side is fixed. Insert the end 21 into the container 50 and submerge the liquid 60 therein to the bottom. Then, the tip of a manual suction pump (syringe) 28 is inserted into the atmosphere-side end 23 of the pipe portion 20, and the suction pump 28 is operated to suck up the liquid 60 to the atmosphere-side end 23 at once. After that, when the tip of the suction pump 28 is pulled out from the atmospheric side end 23, the liquid level on the atmospheric side end 23 side of the liquid column meter 22 is pushed down by the atmospheric pressure, and the liquid level 60A of the liquid 60 in the container 50 is lowered. Stand still at the height of. If the height of the liquid surface of the liquid column meter 22 at this time is read by the scale 30, the remaining amount of the liquid 60 in the container 50 can be easily known. For example, when the central portion of the liquid surface 60A of the liquid 60 in the container 50 is A and the portion of the pipe portion 20 inserted into the container 50 which is in contact with this liquid surface is B, the liquid 60 The liquid surface 60A, that is, the plane including A and B, intersects with the liquid column gauge 22 at C and D as shown, and the position of the liquid level of the liquid column gauge 22 is D. If the liquid level indicator (piece) 32 is moved to E1 on the line connecting C and D, the height of the liquid level 60A can be easily read by the scale 30.

When one of the liquid level indicators (pieces) 32 is aligned with the position of the first liquid level of the liquid 60 in the container 50, for example, E0, the liquid level is lowered by the use of the liquid 60. Sometimes the amount of liquid used can be confirmed. Also, by arranging multiple portable containers side by side and connecting them with siphon pipes, etc., the volume of a large amount of liquid can be checked at the same time with one simple liquid level display device.
