Abstract

PURPOSE: A portable water depth measuring system is provided to automatically and accurately measure depth of water while freely moving. CONSTITUTION: A water depth measuring device(100) is thrown into water to be measured together with a measuring weight(172). The water depth measuring device floats on the water while the measuring weight, bound to a front end of a measuring wire(171), sinks to a bottom under water. The measuring wire, elastically supported by a rubber(152c) of a rotary body, moves together with the measuring weight to rotate the rotary body. A detective sensor(151) detects amount of rotation of a detective disk(152b) of the rotary body. The rotary body stops rotation when the measuring weight reaches the bottom under water so measuring is determined to be complete after a while. The detective sensor transmits detected value to a control part(190) to output to a liquid crystal display(161) for a user to check.

Description

Portable depth measuring device {The measuring instrument of the depth of water}

The present invention is a measurement device that can be used in a variety of fields by measuring the exact depth of the present invention by devising a more improved design based on the priority claims of the patent registration application No. 2001-25320 filed to the Republic of Korea Patent Office In addition, the user can easily and simply measure the depth of the measurement object accurately and automatically as well as easily read and confirm the measurement value and identify the position of the measuring instrument at night, and notify the user after the depth measurement is completed. The present invention relates to a portable depth measuring device capable of accurately collecting and reading the measurement depth, and having high portability, storage, movement, ease of use, and measurement accuracy.

The factors that make life on earth are the critical elements of light, air, earth, heat, light, and water, and these are irreplaceable factors. Among them, water is a tangible and quantitative resource that can be energized as other types of resources such as petroleum, land and minerals, and also has intangible intangible value.

For example, clear water in lakes provides vitality to human life, while quietly flowing rivers provide a means of life for many living creatures and provide transportation to human life. . The value of water as a resource is different from other resources in its tangible and intangible aspects. Since water resources are infinite resources that circulate in uncertainty, other resources can know the limits of development by measuring reserves.However, most of the water resources come from the runoff caused by precipitation in the watershed. Because the precipitation itself is not constant every year, the amount of water as available resources is also uncertain.

However, while most of the obvious resources are reduced by their use, there are no limits for water resources, since almost the same amount can be obtained from the watershed each year without much difference. Therefore, it can be said that it is an infinite resource, and the water used for hydropower upstream can be used for agriculture, industry, and living water downstream, and the wastewater can penetrate underground and become a source of groundwater, and then pump it again. I use it.

The current amount of rain in Korea is 1,159.2 mm per year. This amount is about 60% higher than the world's average of 730mm, but water per capita is 3,100 km3 per year, which is only one tenth of the world average. As two-thirds of annual rainfall is concentrated in June-August, most of it flows into floods and only 23% of total water resources are available. The groundwater estimated by experts is about 232 billion cubic meters, but it has been found to be difficult to develop due to the thin aquifer and the low economic feasibility.

As such, water is an essential resource that is the source of all living things and is an essential raw material not only necessary for the growth of living things but also for the production of general industrial products. That is, about 350 g of water is absolutely necessary to produce 1 g of rice, 150 to produce 1 ton of newspaper, 285 times of iron, 25 times of gasoline, and 2,000 times of rayon, respectively. In addition, if 1.0m3 / s of water continues to flow in a 50m free stream, 353kW of electric energy can be produced. If 1mm of rain falls in the Soyang River basin, 2.7 million cubic meters of water will collect in Soyang Lake. The amount is converted into a value of about 40 million won in terms of electricity. The water flows downstream again and joins the streams of the Han River, providing a beautiful landscape around it, providing the vitality of life and the life of aquatic life.

The value of this water cannot be limited only to the metaphysical values. It is also water that has a higher value than the value criteria such as how much farming is done with the water collected in the reservoir, how many tap water can be supplied to tens of thousands of people in the city, or how many factories can be operated? Depending on how much systematic and efficient management and management of water is the absolute resource, it is obvious that it is fundamental to the basic national economy and life development of the country. Therefore, countries around the world thoroughly manage their own water resources and operate them appropriately and efficiently.

Therefore, the depth of water such as ponds, reservoirs, lakes, rivers, rivers, groundwater and seas can be accurately measured and used as the basis for more systematic and efficient water resources management and operation. In addition, many depth measuring devices have been developed and used to actively use them for various purposes as well as to prevent and cope with them.

As described above, a number of devices for accurately measuring the water depth have been developed and used. Among them, the depth measurement device using the laser beam of patent No. 213599, which is filed in Korea, is briefly described with reference to the accompanying drawings, FIGS. 12A and 12B. As follows.

In the method of measuring the depth of water by reflecting a laser beam, the pipe 20 inserted so that the reflecting sphere 30 reflecting light is movable along the water level surface of the reservoir is installed at a constant angle on the reservoir, and the laser beam generator ( 10) is configured to emit a laser beam toward the substructure 30, to detect the arrival time of the laser beam reflected from the substructure 30 to measure the depth of water.

Here, the pipe 20 of the main hole connected to the laser beam generator 10 and the sub-sphere 30 is inserted into the pipe 20 so as to be movable and coated with a light reflecting material on the surface.

The pipe 20 is formed so that the end portion 21 is bent inward so that the subsphere 30 is not separated from the outside in the pipe 20, and the subsphere 30 is made of a synthetic resin. The chromium layer 32 that reflects light well on the 31 is formed by plating.

However, the above-described depth measurement apparatus using the laser beam has a simple configuration and use method compared to the existing depth measurement apparatus,

First, when the depth measurement requires a pipe having a suitable length and diameter to be installed to the place to be measured, that is, the bottom of the reservoir, there is a disadvantage that the ease of installation, transport and portability, etc. are poor.

Second, a single pipe of 50 to 100 m length with a diameter corresponding to the length should be provided with the corresponding pipe of the maximum depth of the reservoir depth together with additional devices such as a laser beam generator, a measurement readout and a laser beam sensing device. Alternatively, it is necessary to prepare a plurality of pipes formed by being divided into about 1 to 2 m so as to be mutually assembled, and thus it is not possible to simply move the water depth by simply moving it, and to prepare and install / transport / measure a number of preparations for water depth measurement. / Costly defects, such as maintenance costs,

Third, the position of the measurement object cannot be easily changed. Since pipes cannot be moved in the assembled state, they have to be dismantled and then reassembled to measure the water depth.There are many inconvenient shortcomings that cannot satisfy various needs of customers with the merchandise and reliability of the product. There is a problem in that it is impossible to use properly because there is a limit to the measurement object.

Therefore, the present invention was made to solve the fundamental problems of the prior art by improving the patent registration application No. 2001-23520 filed by the applicant of the Republic of Korea Patent Office, the purpose of the depth of the measurement target While moving freely, the user can easily and simply measure the depth of the measurement object automatically and accurately, as well as easily read and read the measurement value and identify the position of the measuring instrument at night. Accurately and easily check the measurement depth The reading and recovery of the device can be easily retrieved. The ease of carrying, storing and using, the accuracy of measurement are high, and the depth can be accurately and conveniently used freely and conveniently without being influenced by the purpose of the measuring product. The present invention provides a portable depth measuring device.
