Description

A tool for fast weighing and measuring body length for silver pomfret farming

technical field

The utility model belongs to the technical field of artificially cultivating silver pomfret in a breeding pond, in particular to a tool for quickly weighing the body weight and measuring the body length for the breeding of silver pomfret.

Background technique

Silver pomfret is one of the important economic fishes along the coast of my country, with high nutritional value and market demand. In recent years, affected by factors such as marine pollution, overfishing and coastal human economic activities, the fishing output of silver pomfret around the world has been declining year by year, so farming will become the main way to meet the market demand of silver pomfret. At present, the bottleneck of artificial reproduction has been broken. However, at present, there is no special tool for weighing and measuring body length in silver pomfret farming, and the method used is also very traditional. Put them into a bucket together, and measure the body length with the naked eye or by taking pictures during the swimming process of the silver pomfret. This traditional weighing and measurement method not only wastes a lot of manpower, but also easily causes damage to the silver pomfret and increases the cost of silver pomfret farming. Therefore, in order to save manpower, it is necessary to invent a tool for fast weighing and measuring body length for silver pomfret breeding, and to improve the traditional and backward weighing and measurement methods in the production process.

SUMMARY OF THE INVENTION

The utility model provides an intelligent, easy-to-operate, high-efficiency weighing and measuring tool for weighing body weight and body length and saving manpower and a method for using the same.

In order to solve the above-mentioned technical problems, the silver pomfret rapid weighing and measuring tool of the present invention includes: a deepened round mouth water spoon, a group of high-sensitivity pressure sensors and a power supply are embedded in the bottom compartment; the input/output lines of the pressure sensor are three, That is, the power line (+ and -) and the voltage output line for outputting the voltage corresponding to the applied pressure, and the final weighing result is output to the display screen from the handle; the bottom of the water spoon is completely covered with a body length measuring board, the board Above are grid lines with a side length of 1cm.

Preferably, the round mouth water spoon is made of plastic material, and is of a deepened type, with an outer diameter of 15 cm, an inner diameter of 12 cm, and a total height of 20 cm. The connecting wires of the pressure sensing device and the display are embedded in the wall of the scoop.

Preferably, the body length measuring plate is made of plexiglass, with a diameter of 12 cm and a thickness of 1 cm, which fits perfectly with the bottom of the water spoon.

Preferably, the cuboid pressure sensor is made of stainless steel, the length of the upper and lower steel bars is 5 cm, and the height of the support spring is 1.5 cm.

The invention uses pressure changes to weigh the silver pomfret and grid lines to measure the body length, which improves the time-consuming and labor-intensive current situation of manual weighing and measurement of the silver pomfret; Risk of Pomfret Injury.

Description of drawings

FIG. 1 is a schematic structural diagram of a tool for rapidly measuring the body weight and body length of silver pomfret in accordance with the present invention.

The tool for quickly measuring the body weight and body length of silver pomfret of the present invention and its use method are described in the accompanying drawings:

1- body length measuring board; 2- body weight monitor; 3- pressure sensor; 4- wire.

Detailed ways

The preparation method of the tool for rapidly measuring the body weight and body length of silver pomfret comprises the following steps:

The first step is to embed a set of high-sensitivity pressure sensors and power sources in the bottom compartment of the deepened round-mouth plastic water spoon, and adjust the threshold of the pressure sensor to the pressure when it is filled with water.

The second step is to install the prepared body length measuring board at the bottom of the water spoon.

In the third step, the pressure sensor is connected to the display circuit at the handle of the water spoon, and the waterproof layer and insulating material are used.

How to use the tools to quickly measure the weight and length of silver pomfrets:

Use this tool directly to pick up the silver pomfret from the breeding pond, and start weighing when the spoon is full of water. The pressure of the silver pomfret is applied to the sensor, and the sensor is elastically deformed, so that the impedance changes, and the excitation voltage is used at the same time. A change occurs, and a changed analog signal is output. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter. Convert it into a digital signal for easy processing and output it to the CPU for operation control. The CPU outputs such results to the display according to keyboard commands and programs. During the process, the silver pomfret in the water spoon is in any position

Users can directly count the number of grids it occupies to convert its body length.

The utility model is simple, easy to operate and strong in practicability, not only can the silver pomfret measurement work be efficiently completed on the premise of not damaging the silver pomfret, but also the labor cost can be reduced to a great extent.

The above examples are only for illustrating the technical concept and technical features of the present invention, and cannot limit the protection scope of the present invention. All equivalent transformations or modifications made according to the essence of the present invention should be included within the protection scope of the present invention.
