Abstract

PURPOSE: A landing net with a strain gage is provided to simplify the fish weight measuring process, to rapidly perform the sorting of desired fish, and to reduce the labor required in a fish farm. CONSTITUTION: The landing net comprised of a net member(1) and a rod(2) is provided with a strain gage(4), an electric wire(8), an A/D converter(5), a liquid crystal display screen(6), a handle, and a battery(7), all of these components are mounted in the rod. When a user receives a fish in the net member, the rod got bent, and the strain gage detects the bending degree of the rod. The electric signal detected by the strain gage is converted into a numeral coefficient by the A/D converter, thereby the user is capable of reading the converted numeral coefficient displayed on the liquid crystal display screen.

Description

Balanced Gardening {A Balance Landing Net}

Electronic scales using strain gauges have already been commercialized, and products such as scales have been sold.

In general, when weighing fish in aquaculture farms, the fish are lifted and floated on a scale to weigh the fish. If the fish does not meet the weight of the standard is sent back to the water, in order to simplify this process in one step, the inventors have invented a device that can measure the weight of the fish just by lifting the fish out of the net. Balanced gardening allows you to quickly select fish of the desired size.

The principle of the present invention that can measure the weight in the landing net by mounting the electronic balance on the landing net is as follows.

① The user grabs the handle (3) of the gardening net and puts the object in the net (1).

② The rod (2) causes bending deformation due to the weight of the object.

③ Strain gauge (4) detects the degree of bending.

④ The A / D converter 5 converts the electrical signal sensed by the strain gauge 4 into a counting type.

? The signal changed into the counting form in the A / D converter 5 is displayed on the liquid crystal display 6.

(6) The user reads the value of the LCD screen (6).

-. Tie the scale and scales currently in use.

-. The weight can be measured at the same time as the object is lifted with the net.

-. You can see the weight of the fish caught by fishing only.

-. The use of the present invention in aquaculture can speed up the selection of fish.

-. Reduce labor of fishers in fish farms.
