Description

Technical Field

[0001] The utility model relates to the field of measurement and testing, in particular to a testing device for measuring the shell diameter, shell height and total weight of a purple sea urchin. Background Art

[0002] The gonad index of a sea urchin is an important indicator for evaluating its yield and quality, and has a direct impact on the market price of the sea urchin. The gonad of the sea urchin, that is, its edible reproductive gland, is the key part for evaluating the quality of the sea urchin. The gonad index is also the main factor affecting the market price of the sea urchin. Since the gonad traits cannot be measured in vivo, the breeding of the gonad quality can only be carried out by indirect methods. As an important parameter among them, the gonad index directly reflects the reproductive ability and reproductive health status of the sea urchin, thus indirectly affecting its economic value. Only the sea urchins with qualified gonad indices can be put on the market for sale, while the unqualified sea urchins need to be put back to the breeding ground for continued breeding.

[0003] When evaluating the gonad index of a sea urchin, it is necessary to obtain the shell height, shell diameter and weight of the sea urchin. In the prior art, a tape measure or a caliper is usually used to measure the size of the sea urchin, and then a kitchen scale or a laboratory scale is used to measure the weight of the sea urchin. First of all, the measurement accuracy of the tape measure and the caliper is not accurate enough, and the reading error will affect the evaluation result. Secondly, the experimenter needs to pick up the sea urchin and then use the tape measure or the caliper for measurement. It is inevitable that the experimenter will be injured by the sea urchin spines during the measurement process. Finally, the kitchen scale or the laboratory scale requires manual reading and statistics, and screening sea urchins requires a large amount of data to be counted and calculated, resulting in an increased burden on reading and calculation, reduced evaluation efficiency, and thus increased labor costs.

[0004] Therefore, a testing device for the shell diameter, shell height and total weight of a purple sea urchin is provided to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a testing device for the shell diameter, shell height and total weight of a purple sea urchin, which can conveniently and accurately measure the external dimensions and total weight of the sea urchin shell, avoid the experimenter from being accidentally injured by the sea urchin spines, and at the same time predict the relationship of the gonad index to judge whether it can enter the market, so as to effectively solve the actual production needs of fishermen.

[0006] To achieve the above object, the utility model provides a testing device for the shell diameter, shell height and total weight of purple sea urchins, which includes a measuring scale vertically arranged on a test bench and a small weighing scale horizontally arranged on the surface of the test bench. The tail end of the measuring scale is connected to the upper surface of one side of the small weighing scale.

On the side of the measuring scale away from the electronic vernier caliper, there are an electronic display screen and a data cable. The data cable is connected to a computer through a USB interface.

[0007] Preferably, a slider is arranged on the electronic slide rail, and a limiting hole is arranged on the electronic vernier caliper. A limiting nail passes through the limiting hole to fix the electronic vernier caliper on the slider. A small horizontal positioner is arranged on the electronic vernier caliper to ensure that the electronic vernier caliper is fastened in the electronic slide rail and remains horizontal, avoiding measurement errors caused by the inclination of the electronic vernier caliper.

[0008] Preferably, the small horizontal positioner is arranged at any position between the end of the electronic vernier caliper close to the slider and the electronic display arranged on the electronic vernier caliper.

[0009] Preferably, the computer is provided with a gonad index evaluation model. The output parameters of the gonad index evaluation model include the gonad index and the difference between the predicted weight and the actual weight.

[0010] Preferably, the gonad index is obtained by the ratio of the gonad weight to the total weight.

[0011] Preferably, the method for calculating the predicted weight is represented by the product of the square of the shell diameter and the shell height / 1000.

[0012] Therefore, the testing device for the shell diameter, shell height and total weight of purple sea urchins with the above structure of the utility model has the following beneficial effects:

[0013] (1) It can accurately display the shell diameter, reduce the reading burden and error, and meet the accurate measurement requirements;

[0026] Embodiment

[0027] Place the sea urchin on the small weighing scale 3, and the electronic display screen 5 will display the shell height and weight data of the sea urchin. Compared with the traditional scale and human eye reading, the electronic measurement can accurately display the shell height and weight of the purple sea urchin. The electronic vernier caliper 8 moves up and down along the electronic slide rail 11 of the measuring scale 2. While measuring the shell height, use the electronic vernier caliper 8 to clamp the sea urchin across the spines. The electronic display 9 of the electronic vernier caliper 8 can accurately display the shell diameter, reducing the reading burden and error, and also preventing the experimenter from being injured by the spines during measurement.

[0028] The left end of the measuring scale 2 is connected to a data cable 6 and a USB interface 7 for connecting to a computer. The shell diameter, shell height, and weight of the measured sea urchin by the device will be imported into the computer. By the dimensional analysis method, since the volume is equal to the product of the square of the shell diameter and the shell height, it can be obtained by data analysis and comparison that: the predicted weight is equal to the product of the square of the shell diameter and the shell height / 1000, and the gonad index of the sea urchin can be evaluated from the error value between the predicted weight and the actual measured weight, because when the gonad index is different, the difference between the weight predicted from the shell appearance size and the actual weight can be used to evaluate the gonad index. According to 235 healthy cultured samples of purple sea urchins taken in the experiment, their shell diameters, shell heights, weights, and gonad weights are measured, and the gonad index is calculated. The requirement for the gonad index of purple sea urchins entering the market demand reaches more than 8%.

[0029] As Figure 3 shown, when the weight error obtained by importing data is between -16 and 12, the total sample is 105, the unqualified sample is 80, and the qualified sample is 25. Then, 76% of the purple sea urchins have a gonad index that does not reach the qualified level. Then, it can be obtained that the purple sea urchins within the error range calculated from the appearance size need to be cultured continuously and cannot yet enter the market, reducing the slaughter and misjudgment costs of farmers.

[0030] Therefore, the present utility model adopts a testing device for measuring the shell diameter, shell height and total weight of Anthocidaris crassispina with the above structure, which can conveniently and accurately measure the appearance size and total weight of the sea urchin shell, avoid the experimental personnel from being accidentally injured by the sea urchin spines, and at the same time predict the relationship of the gonad index to judge whether it can enter the market, thus effectively solving the actual production needs of fishermen.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
