Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an abalone measuring instrument, and more particularly to an abalone measuring instrument for measuring whether or not an abalone size is equal to or larger than a specified size that can be captured.

[0002]

[Prior art]

 In recent years, the reduction of marine resources due to overfishing and destruction of nature has become a major problem worldwide, but in Japan, the amount of abalone, which has weak proliferative capacity and takes a long time to grow, is decreasing year by year. Therefore, in order to stop such a decrease in the amount of abalone caught, conservation measures have come to be taken at fishing grounds in various regions, where abalone that does not reach the prescribed size during fishing is returned to the sea without being caught.

[0003]

[Problems to be solved by the device]

 This measurement and selection work is performed by a sea diver or fisherman using a measuring instrument that is flat and has a concave part on one side to fit abalone, but it is unstable because it shakes at sea, and gloves are put on. It was difficult to handle a wet measuring instrument by hand, and the measurement work was quite time-consuming.

Therefore, in view of the above-mentioned inconveniences and the like, it is an object of the present invention to provide an abalone measuring device that is easy to use and can quickly measure the size of an abalone to improve work efficiency. It was devised.

[0005]

[Means for Solving the Problems]

 For this reason, the present invention is an abalone measuring instrument that is a flat, generally U-shaped plate that measures whether or not an abalone has reached a prescribed size by inserting an abalone into one of the recesses. Alternatively, it is made of a synthetic resin material having buoyancy with respect to seawater, and a part or all of the peripheral portion is thickly formed, and is surrounded by a frame portion protruding at a suitable height on at least one surface. The above-mentioned problem is solved by providing the display unit.

[0006]

[Embodiment of the invention] 【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 shown in the drawing is a measuring device main body formed of a synthetic resin material (polyethylene resin in the illustrated example) having a buoyancy against water or seawater into a substantially U-shaped plate in a plane. The measuring instrument main body 1 is fitted with the abalone A in the recess 2 on one side and whether or not the abalone A has grown to a predetermined size, that is, the abalone A is in contact with the opposite side of the recess 2 at the same time or is fitted in the recess 2. If it is not possible, it is recognized that the abalone A has grown to a size larger than the specified size, and if the abalone A cannot contact the opposite sides of the recess 2 at the same time, it is recognized that the abalone A has not grown to the specified size. Therefore, the length between the opposite sides of the concave portion 2 is set to a predetermined dimension which is defined as a criterion of whether capture is possible. It should be noted that this size is specified by the fishing grounds in each region, and varies depending on the location. For example, the size is 65 mm for the North Kaido and 90 mm for the six Tohoku prefectures.

The measuring device main body 1 has a thick entire peripheral edge portion 3 including the concave portion 2, which makes it easy to handle without a slip even with a fingertip of a work gloves during measurement work. It is strong enough to withstand many years of use without being damaged by being hit or dropped. In the illustrated example, the entire peripheral portion 3 of the measuring device body 1 is formed thick, but as another embodiment, a part of the peripheral portion, for example, the peripheral portion is formed thick at appropriate intervals. Even so, it can have a non-slip effect and strength.

A display unit 4 is provided on one side of the measuring device main body 1 for displaying a user name, a name of an affiliated organization, etc. by means of oil-based paint, engraving or the like. The display section 4 is surrounded by a frame section 5 which protrudes at a suitable height, so that the display contents of the display section 4 are not worn.

Reference numeral 6 is a cord through hole for attaching the cord through the cord. The cord attached to the cord through hole 6 is connected to the waist of an operator or the like so that the measuring device main body 1 is separated from the hand during the work at sea. However, it will not only be lost, but also lost.

The measuring device main body 1 of this embodiment, when the string attached to the string through hole 6 is connected to the waist or the like and enters the sea, catches the abalone A and rises to the sea surface, the recess 2 The size of the abalone A is measured and sorted, and the measuring device main body 1 floats on the sea surface and can be pulled by a string, so that the work can be performed easily.

Further, in the above-described embodiment, one display portion surrounded by the frame portion is provided on one surface of the measuring device main body 1, but the present invention is not limited to this, and a plurality of display portions may be provided on both front and back surfaces. It may be provided.

Needless to say, the shape, size, material and configuration of the measuring device main body, and the shape, size and configuration of the frame portion and the display portion are not limited to those in the above-mentioned embodiments.

[0013]

[Effect of the invention]

 According to the present invention configured as described above, an abalone measuring instrument is a plate having a substantially U-shaped plate shape, and the abalone A is fitted into the recess 2 on one side to measure whether or not the abalone A has reached the predetermined size. Therefore, the measuring device main body 1 is formed of a synthetic resin material having buoyancy with respect to water or seawater, and a part or all of the peripheral portion is formed thick, and at least one surface of the measuring device main body 1 is formed. Since the display part 4 surrounded by the frame part 5 that protrudes at an appropriate height is provided in the instrument, the measuring instrument body 1 floats on the sea surface even if it is dropped during the work or removed from the hand, so it can be picked up without losing sight. it can.

In addition, since the measuring device main body 1 has a part or all of its peripheral edge formed to be thick, it is easy to grasp even with the fingertips of gloves when working, and has strength that can withstand long-term use. It was equipped with and.

Further, since the display portion 4 surrounded by the frame portion 5 protruding at an appropriate height is provided on at least one surface, the desired user name, affiliated organization name, etc. are written on the display portion 4 and the owner is indicated. It can be clarified so that it can be returned to the owner when it is lost, and the protruding frame portion 5 can protect the display content of the display portion 4 from being worn away.

As described above, according to the present invention, since it has excellent durability, it can be used for many years, and since it is easy to handle, abalone measurement work can be performed quickly and work efficiency is improved. In addition, it has an extremely useful effect in practical use, such as a simple structure and low cost for manufacturing and providing.
