Abstract

Amount fish scale, comprises the scale pan on scale body and scale body, the scale pan is installed with base, its base is installed with by the lower amount fish plate of the affixed one-tenth of the plate of two panels comb-shape " V " shape; Also comprise a upper amount fish plate that can be separated with lower amount fish plate, described upper amount fish plate is by the amount fish plate of the affixed one-tenth of the plate of two panels comb-shape " V " shape, and is installed with rule in the side of upper amount fish plate; " V " shape angle of described upper amount fish plate and lower amount fish plate is between 30 degree to 80 degree; When upper amount fish plate and lower amount fish plate close, comb on upper amount fish plate is arranged in the gap of two interval combs on lower amount fish plate, the utility model provides a kind of amount fish scale, the body weight of large small fish and body progress row can measure accurately the difference of just having caught up, the time of measuring fish is shortened, reduce scale to come off, improve the survival rate of fish.

Description

Amount fish scale

Technical field

The utility model belongs to ecology of fishes and physiological field of scientific study, relates to a kind of amount fish scale.

Background technology

Long and the body weight of the body of fish is ecology of fishes and a physiological important indicator, when the long and measured body weight of body being carried out to the fish of the different sizes of catching up in the wild be first will be laid in plane, be measure fish with tape measure and scale to grow and body weight; Fish can cause coming off of flap because of struggling in this process, and is difficult to place stable with fish, adds fish aerial open-assembly time, adds dead probability; And when weighing, data on scale also can be made because of the struggle of fish and then to swing, affect the accuracy of measurement result.

Summary of the invention

The utility model provides a kind of amount fish scale, the body weight of large small fish and body progress row can measure accurately, the time of measuring fish is shortened, reduces scale and come off, improve the survival rate of fish the difference of just having caught up.

In order to solve the problem, the technical solution of the utility model is:

Amount fish scale, comprises the scale pan on scale body and scale body, the scale pan is installed with base, its base is installed with by the lower amount fish plate of the affixed one-tenth of the plate of two panels comb-shape " V " shape; Also comprise a upper amount fish plate that can be separated with lower amount fish plate, described upper amount fish plate is by the amount fish plate of the affixed one-tenth of the plate of two panels comb-shape " V " shape, and is installed with rule in the side of upper amount fish plate; " V " shape angle of described upper amount fish plate and lower amount fish plate is between 30 degree to 80 degree; When upper amount fish plate and lower amount fish plate close, the comb on upper amount fish plate is arranged in the gap of two interval combs on lower amount fish plate.

Two ends near two comb plate junctions on described upper amount fish plate are installed with lashing post.

Two ends near two comb plate junctions on described lower amount fish plate are installed with lower lashing post.

Upper lashing post and lower lashing post are provided with elastic component.

Described upper amount fish plate and lower amount fish plate adopt transparent PVC material to make.

Technique effect of the present utility model is:

Measure the comb-shape shape that fish plate is " V " shape up and down, and upper amount fish plate can be inserted in lower amount fish plate, distance between its twice amount fish plates can change, and then the fish of different size can be measured, when fish is put on covering, measure fish plate after in lower amount fish plate time, its combination shape be rhombus, cross sectional shape due to fish is spindle, so when fish being put into the rhombus be made up of each fish plate, the scope of activities of fish can well be limited, and then reduce struggle; It measures fish plate is up and down transparent PVC material, and is installed with rule on upper fish plate, is on the body in order to be convenient to when allowing fish between two fish plates by the transparent plate of fish up and down reading fish and the state of observation fish; Lashing post and elastic component on it are for the ease of accuracy when operation and measurement body weight.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 the utility model is measured three-dimensional structure diagram when fish plate and lower amount fish plate separate;

Fig. 2 the utility model is measured three-dimensional structure diagram when fish plate and lower amount fish plate close;

Fig. 3 is the sectional view of the utility model when measuring fish;

In figure: above measure fish plate 1, base 2, scale body 3, the scale pan 4, lower amount fish plate 5, upper lashing post 6, lower lashing post 7, rule 8, elastic component 9, fish body 10.

Embodiment

As illustrated in fig. 1 and 2, a kind of amount fish scale, comprises the scale pan 4 on electronic balance body 3 and scale body 3, the scale pan 4 is installed with " V " shape base 2, its base 2 is welded with by the lower amount fish plate 5 of the affixed one-tenth of the plate of two panels comb-shape " V " shape; Also comprise a upper amount fish plate 1 that can be separated with lower amount fish plate 5, described upper amount fish plate 1 is by the amount fish plate of the affixed one-tenth of the plate of two panels comb-shape " V " shape, and is installed with rule 8 in the side of the close junction of upper amount fish plate 1; Described upper amount fish plate 1 and " V " shape angle of lower amount fish plate 5 are between 30 degree to 80 degree; When upper amount fish plate 1 and lower amount fish plate 5 close, the comb on upper amount fish plate 1 is arranged in the gap of two interval combs on lower amount fish plate 5.

Two ends near two comb plate junctions on described upper amount fish plate 1 are installed with lashing post 6.

Two ends near two comb plate junctions on described lower amount fish plate 5 are installed with lower lashing post 7.

Upper lashing post 6 and lower lashing post 7 are provided with bungee.

Described upper amount fish plate 1 and lower amount fish plate 5 adopt transparent PVC material to make.

During use, as shown in Fig. 1 to 3, first upper and lower support plate is separated, the fish caught up is positioned on lower supporting plate, now buttresses fish body 10, and the fish maw of fish or the fish back of the body are placed down, then fetch upper backup pad to be buckled on the fish back of the body or fish maw, and now upper and lower comb is staggeredly placed; Then fetch bungee and upper and lower lashing post 7 is fixed the struggle that can reduce fish, read fish length by rule 8 simultaneously, read the body weight of fish by electronic scales; After complete data to be recorded, fish is freeed or carries out next step research; The weight of upper and lower supporting seat body can adopt electronic scales to measure in advance.
