Abstract

(57) [Abstract] [Purpose] In order to measure the distance to the water surface of a rainwater tank installed underground (under the floor), a structure in which a float with a certain weight and a grip ring are tied with a scale string , The string is pulled up and the distance to the water surface is measured at the position where the string feels the weight of the pin and the tensioner. [Structure] A small hole through which a cord passes is penetrated through the floor, and a measuring cord is passed therethrough, and the upper end is connected to a grip ring and the lower end is connected to a heavy float.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 When the rainwater storage tank is an underground (underfloor) tank with a concrete structure, it is used to easily measure the distance from the floor surface to the water surface.

[0002]

[Prior art]

 Traditional methods of measuring the distance from the floor to the surface of the water have included the use of a scale, the sticking of a fixed sign on the float, or an electronic signal. It was In general, the installation location is often small, and in either case, it was either inconvenient or expensive.

[0003]

[Problems to be solved by the device]

 In order to measure the water level of an underground (underfloor) tank in a small space, it is almost impossible to insert a measuring scale, and a place for storing the measuring scale is also necessary, and it may be lost. There are cases where the method of protruding the fixed sign on the float is not allowed due to space limitations. As a method to solve this problem, we have devised a measuring method using the float-pulling method.

[0004]

[Means for Solving the Problems]

 A float with a certain weight is floated on the plain water surface. Attach a string with a measuring scale to it, and hang the string from the floor. When the string pulls up and lifts the underwater part of the float, you feel the weight of the pulling hand. If you read the scale of the string at that time, the distance to the water surface will be measured. The structure is simple, and it can be operated in a narrow space such as under stairs, not in a storage space like a weighing scale.

[0005]

[Action]

 The float has a certain weight, and it is made to float on the water. Make a small hole in the concrete floor (the ceiling of the aquarium) and connect the grip ring and the float with a certain length using a string with a measuring scale. When the string is struck, the string is taut and the float rises. At this time, the hand holding the grip ring feels heavy. Since the scale attached to the string at that time can be read, anyone can easily operate it, and the distance to the water surface can be measured extremely accurately.

[0006]

【Example】

 A water level measuring device of this type was installed in a place where the lower part of the staircase at the entrance of the newly built house was used as a rainwater tank. It was popular because it can be measured accurately without taking place or worrying about dying.

[0007]

[Effect of device]

 The pump was installed in the limited space behind the stairs, which was invisible at the entrance to the entrance, and could be installed in a place where there was no room to spare. The operation is extremely accurate and easy for anyone to understand.
