specific Embodiment approach 1

[0007] Embodiment 1: Combining Figure 1-Figure 3 Illustrating this embodiment, the platform of this embodiment includes a fish measuring platform, two support platforms 2, two main slide rules 3, two auxiliary slide rules 4, two spools 6, two springs 7, two Lock nut 8, two sliding screws 9 and at least two sliding needles 5; the fish measuring platform includes baffle 1-1, rectangular horizontal plate 1-2 and rectangular vertical ruler plate 1-3, baffle 1-1 along the rectangle The horizontal direction of the horizontal plate 1-2 is vertically arranged at one end of the upper surface of the rectangular horizontal plate 1-2, and the rectangular vertical ruler plate 1-3 is vertically arranged on the upper surface of the rectangular horizontal plate 1-2 along the longitudinal direction of the rectangular horizontal plate 1-2. On one side, the baffle 1-1, the rectangular horizontal plate 1-2 and the rectangular longitudinal plate 1-3 are fixedly connected as a whole, and the upper...

specific Embodiment approach 2

[0008] Specific implementation mode 2: Combining figure 1 Describing this embodiment, the height of the baffle 1-1 in this embodiment is 20-150mm, the length is 100-250mm, and the length of the rectangular longitudinal plate 1-3 is 200-800mm. The above dimensions conform to the fish shape standard. Other embodiments are the same as the first embodiment.

[0009] Working principle: When measuring the shape index of fish, measure according to the position of each index specified in the National Standard of the People's Republic of China - Inspection of Cultured Fish Germplasm Part 3: Determination of Characters GB / T 18654.3-2008. On each support table 2, the two spools 6 and springs 7 are adjusted so that the head and tail axes of the fish and the dorsal and ventral axes are on the same level, and the positioning is carried out by the sliding screw 9, and the measurement is started, among which the total length, body length, body thickness , head length, head length behind the ...

Abstract

The invention discloses measuring equipment for a fish shape, and relates to a device for measuring a fish-shaped indicator. According to the invention, the problems that the existing fish measuring plates need to measure a fish-shaped indicator with the assistance of a triangular rule, a caliper gauge and a caliper rule, the measuring speed is low and the data is inaccurate are solved. A baffle, a rectangular horizontal plate and a rectangular longitudinal rule plate are fixedly connected into a whole, two support platforms are arranged on the rectangular horizontal plate, a slideway is arranged on the rectangular horizontal plate, each support platform is connected with the rectangular horizontal plate in a sliding way by a traveller, one end of the traveller penetrates through the rectangular horizontal plate to the arranged outside the rectangular horizontal plate, the side wall of each sliding screw is provided with a wedge-shaped slot along a vertical direction; each sliding screw penetrates through the side wall of the rectangular horizontal plate, props against the traveller by the wedge-shaped slot, and is locked by a lock nut; each main sliding scale is provided with an auxiliary sliding scale and is vertical to the auxiliary sliding scale, and one of the two auxiliary sliding scales is provided with two wipers. The measuring equipment is used for measuring cyprinid-fish-shaped data indicators.

Description

technical field [0001] The invention relates to a device for measuring the shape index of fish. Background technique [0002] In the process of quantitative trait measurement of individual external morphology of fish growth and species germplasm inspection, the straight-line distance of several indicators is often measured by using a fish plate. The existing fish measuring board only plays the role of a carrier. The head and tail axes of the fish body must be parallel to the vertical baffle on the back of the fish measuring board, and the determined vertical distance will be affected by human subjective factors. At the same time, a triangle ruler is needed to assist. , can measure the two indicators of full length and body length; and other indicators can only be measured with the help of calipers and calipers, the operation is cumbersome, and the measurement speed is very slow. Furthermore, the bottom surface of the fish measuring plate is the water platform surface, and w...
