Description

  The present invention relates to a float-type water level meter, and more particularly to a float-type water level meter capable of checking a water level visually for a long period of time.

  When storing water, etc., a water storage tank (hereinafter referred to as “tank”) is used. Usually, a cylindrical pipe (bypass pipe) is attached to the outside of the tank in order to easily check the water level. The water level is confirmed visually. Moreover, the water level is also confirmed by using a transparent or nearly transparent material for the tank itself without using a water level gauge. Further, as a method for confirming the water level other than by visual observation, a method of confirming the water level by outputting it to the outside using a float type water level sensor or an electrical signal is known. These water level gauges also have a function to automatically stop water when the tank is full.

  The present invention is intended for a water level gauge used in a tank that does not have a water level gauge in the tank itself, but mainly checks the water level visually.

  In the conventional water level confirmation method in the prior art, when the liquid to be stored is a liquid that easily adheres to the scale or the like, the scale or the like adheres to the inner wall surface or the cylindrical tube, making it difficult to visually confirm the water level. The cylindrical tube is clogged with deposits and does not show the correct water level, and the reliability of water level confirmation is lacking. There is also a water level meter in which a float is contained in a cylindrical tube, but in this case as well, there is a possibility that the float may not move due to a scale attached to the cylindrical tube. As a result, work such as cleaning of the tank and the cylindrical tube occurs, requiring time and labor, and in some cases, there is no appropriate cleaning means, and replacement may be forced.

  In addition, when the tank itself does not have these water level gauges, a large amount of work such as remodeling or replacement of the tank is required, and a large amount of money is generated.

  The float type water level gauge has a structure in which the float inside the water level gauge moves up and down as the water level changes, so that the water level gauge can be seen from the outside of the tank. When a water level meter is placed in the tank, at least the water level meter corresponding part of the tank wall is made of a transparent material such as glass. In this case, when a liquid that easily adheres to a scale or the like is stored, the scale or the like adheres to the inner wall surface of the bypass pipe or the inner wall surface of the tank, making it difficult to visually confirm the water level.

An object of the present invention is to provide a water level meter that can be easily attached to a tank that does not have a water level meter, prevents or removes deposits such as scales, and maintains high visibility.
It is another object of the present invention to provide a water level meter that can automatically stop water when the tank is full.

The present invention is a float type water level meter formed by providing a cleaning member to the float part of a float type water level meter.
In a preferred embodiment, the float type water level meter of the present invention is such that the cleaning member is made of a brush, sponge or spatula.

  In a preferred embodiment when the water level meter is arranged in the tank, the float type water level meter of the present invention has a vertical shaft member to which the float part is movably attached, and the vertical shaft member has a length adjusting mechanism and in the water storage tank. And a fixing member for fixing the vertical shaft member. In an even more preferred embodiment, the float type water level gauge of the present invention has a float switch at the top thereof.

  According to the present invention, by attaching a cleaning member such as a brush to the float part of the water level gauge, the inside of the bypass pipe or tank will be cleaned according to the change in the water level, so that dirt such as scales and algae will not adhere to it. Even if it adheres, it can be easily removed, so that high visibility can be maintained for a long time.

  In this case, a cleaning member such as a brush may be brought into contact with the inside of the tank with a slight force, and various types of plastics, rubbers, foams thereof, and the like can be made into appropriate shapes.

  Also, in a preferred mode when the water level meter is arranged in the tank, the vertical shaft member can be expanded and contracted, and fixed members are provided on the upper and lower sides so that it can be easily attached to tanks of different sizes without modification of the tank. it can.

  In a preferred embodiment, water storage can be automatically stopped by incorporating a switch in the upper part of the vertical shaft member so that the float comes to the position and operates when the tank is full.

Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing an example of the apparatus of the present invention, and FIG. 2 is an explanatory view showing a stretched state of a water level gauge.

  The vertical shaft member (frame) 1 is formed of a cylindrical body, and a fixing member (tank presser) 2 whose length can be adjusted is attached to the upper and lower sides thereof. A float 3 having a structure that floats on water is attached to the vertical shaft member 1. The float 3 is provided with a cleaning member 4 such as a brush, sponge, or spatula, and a magnet. A switch 6 is built in the upper part of the vertical shaft member.

  The vertical member 1 and the fixing member 2 are preferably attached so that the length thereof can be adjusted with screws. In such a case, by rotating the fixing member 2, as shown in FIG. 2, it is possible to change the total length of the water level gauge and attach it to various tanks having different sizes. Other suitable expansion / contraction methods can also be employed.

FIG. 3 is an explanatory diagram showing the operation of the float.
Since the float 3 floats in the water as shown in FIG. 3, the float 3 rises in the same manner as the tank water level, so that the water level can be easily confirmed by the float 3, and at the same time the cleaning member 4 reaches the tank inner wall surface. Since the cleaning member 4 rubs against the inner wall surface of the tank by disposing the water level meter in the tank, it is possible to prevent the deposits from adhering to the tank and remove the deposits, thereby making it easy to check the water level.

  Further, an external valve (not shown) that is interlocked is turned on / off when the float 3 containing the magnet 5 rises and reaches the switch 6 built in the upper part of the vertical shaft member 1. It becomes possible to close and stop water storage in the tank.

  FIG. 4 is a schematic view showing a modification of the present invention. As shown in FIG. 4, by inserting a brush attached to the entire circumference of a plate that matches the size of the tank into the tank, the deposits on the entire circumference of the tank can be removed every time the water level changes. It becomes possible.

  5 and 6 are schematic views showing another example of the apparatus of the present invention. FIG. 5 shows a U-shaped bypass pipe and FIG. 6 shows an L-shaped bypass pipe attached to the outside of the tank. The state where the float which provided cleaning members, such as a brush, to the peripheral part was arranged in the pipe is shown. Similarly to the above, every time the water level changes, the deposits on the inner wall of the bypass pipe can be removed to maintain high visibility.

  Although the water level meter of the present invention is mainly used in a water storage tank, it can also be used in various water tanks and liquid storage tanks other than water, and the use thereof is also included in the present invention.
