Description

[Detailed Description of the Invention] The present invention is a pool water capable of observing the horizontal transparency in the water from above without lurking in the water when observing and measuring the transparency of the water in order to examine the contamination of water in the pool. The present invention relates to a transparent observation stand.

Conventional technology When investigating water stains in the pool,
An observer dives into the water and observes the horizontal identification distance in the water to measure the transparency of the water.

Problems to be Solved by the Invention However, when measuring the transparency of water in order to check the contamination of water in the pool, it is necessary for the observer to dive into the water each time it is necessary to change clothes,
In addition, it is extremely troublesome and troublesome such as getting the body wet.

An object of the present invention is to provide an extremely convenient mirror stand for observing the transparency of pool water, which allows an observer to observe and measure the horizontal transparency in the water from above the water around the edge of the pool without diving into the water. Is.

Means for Solving the Problems The configuration of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the examples. The end plate 8 is set at an angle of about 45 degrees and is obliquely installed on the frame base 7, and the bottom floor in the pool P,
It is characterized in that it is submerged in a required place such as an underwater side wall surface or an underwater upper layer portion.

The end plate 8 obliquely installed at an angle of approximately 45 degrees on the frame base 7 submerged at a required position such as the floor surface, the underwater side wall surface, and the underwater upper layer portion in the pool water has a horizontal view in the water at the submerged position. Will be projected approximately 90 degrees upward.

Therefore, the observer can obtain a horizontal field of view in the water by looking down the mirror plate 8 directly above the mirror stand without submerging in the water, and appropriately keep a predetermined distance from the side wall surface or the like. It is possible to observe and measure the transparency of a target object by identifying it.

Example Hereinafter, an example of the present invention will be described with reference to the drawings, in which a horizontal plane portion 2, a sloped surface portion 3 and a vertical surface portion 4 set at approximately 45 degrees are bent and continuously formed by using a synthetic resin plate 1. Triangular side plates 5 and 6 are attached to the left and right side edges of the horizontal plane portion 2 and the inclined surface portion 3 to form a frame base 7, and an end plate 8 is attached to the surface of the inclined surface portion 3 of the frame base 7. The end plate 8 is obliquely held at an angle of about 45 degrees. The size of the end plate 8 is not specified, but a size of about 20 cm × 30 cm is suitable.

In the figure, 9 is a perforation formed in the vertical surface portion 4 of the frame base 1,
Reference numeral 0 denotes a frame-shaped peripheral frame surrounding the end plate 8 on the inclined surface portion 3 of the frame base 7.

The mirror pool for observing the transparency of the pool water of the present invention constructed as described above is installed such that the bottom surface of the horizontal plane portion 2 is in contact with the bottom floor of the corner of the water in the pool P as shown in FIG. Vertical surface part 4 at any place on the underwater side wall surface of pool P
By attaching or suspending them so that their backs are in contact with each other, they can be kept in a horizontal position at an appropriate position that does not hinder the swimmer in water at all times or when they are submerged when necessary, or only when necessary. The fingers are grasped by passing through the perforations 9 formed in the vertical surface portion 4 of the table 7, and are held submerged in the upper water portion of the pool P at a position within the reach of the drooping arm.

When the observer looks down at the mirror plate 8 located immediately below from the water on the periphery of the pool P, the mirror plate 8 is obliquely held at about 45 degrees, so that the mirror plate 8 can be seen in the horizontal direction in the water through the mirror plate 8. Therefore, the transparency of water can be observed and measured by identifying the side walls and other appropriate targets that face each other at a predetermined interval.

Effects of the Invention The present invention is as described above, and the observer can observe the horizontal direction in the water while staying on the water at the edge of the pool without diving under the water in the pool, and the transparency of the pool water is extremely easy. It has a practical effect that it can be observed and measured, and that it has an extremely simple structure and can be provided at a low price and is easy to implement.
