Problems solved by technology

However, when the nets are being fished in the sea or the number of nets is large (for example, the number of nets exceeds 1000), the method of manual counting has great limitations
Moreover, the manual counting method takes a long time, has low efficiency, and has large errors

Embodiment Construction

[0032] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0033] Such as figure 1 , figure 2 Shown, a kind of fast measuring device of mesh number of fishing gear, comprises:

[0034] A measuring piece, the measuring piece is provided with a grid with a scale;

[0035] A marking piece, the marking piece can be marked on the surface of the measuring piece.

[0036] In the present embodiment, the measuring piece is a non-woven fabric (1) with a surface layer structure, and the size of the non-woven fabric (1) can be formulated and designed according to the fishing gear of the mesh number to be measured. When the fishing gear with the mesh number to be tested is very large, the mesh number is many,...

Abstract

The invention discloses a rapid measurement device of the number of fishing gear net meshes. The rapid measurement device comprises: a measurement component, wherein grids with scales are arranged onthe measurement component; and a marking component, wherein the marking component can be marked on the surface of the measurement component. A rapid measurement method of the number of fishing gear net meshes by using the rapid measurement device of the number of fishing gear net meshes comprises the following steps: step 1: flatly paving the measurement component, step 2: fixing one end of a fishing gear to one grid of the measurement component; step 3: unfolding the fishing gear, and marking the fishing gear on the measurement component by using the marking component; and step 4: taking awaythe fishing gear, and quickly calculating the number of horizontal net meshes and the number of longitudinal net meshes by counting the number of horizontal and longitudinal marks in the unit grid and the total number of grids covered by the marks. By adoption of the rapid measurement device disclosed by the invention, the the number of net meshes can be obtained quickly, efficiently and accurately; and furthermore, the rapid measurement device can be washed with water after use and can be reused for many times.

Description

technical field [0001] The invention relates to a device for measuring the mesh number of fishing gear, in particular to a device for quickly measuring the mesh number of fishing gear and a method for quickly measuring the mesh number of fishing gear. Background technique [0002] Fishing gear is a tool for directly catching aquatic economic animals in oceans and inland waters. Fishing gear can be divided into 12 categories according to the operating principle. Among them, net fishing gear accounts for 7 categories, including: gill nets, seine nets, trawl nets, spread nets, ground nets, spread nets and dip nets. The number of meshes refers to the number of longitudinal, horizontal or circumferential meshes of the fishing gear (such as figure 1 shown). Mesh number is an important technical parameter of net fishing gear, which is of great significance to the manufacture, test and optimization of net gear. For example, the horizontal and vertical mesh numbers of gillnets ar...
