Abstract
The utility model relates to a fish length measurement device, and in particular relates to a linear measurement device for large fish in ocean. The measurement device structurally comprises a main ruler with reading scales, wherein a fixed rod is perpendicularly arranged at one end of the main ruler; the main ruler is sleeved with a sliding rod; the sliding rod can move on the main ruler; the sliding rod is parallel to the fixed rod; an inner groove is formed in the inner side of the fixed rod; and the scale reading of the main ruler is zero when the sliding rod is fitted with the fixed rod. When the measurement device is used for measuring, one end of a fish body is placed in an inner groove in the inner side of the fixed rod, the other end of the fish body corresponds to the sliding rod, and the length of the fish is measured by movement of the sliding rod. The measurement device is simple in structure and high in measurement accuracy, and facilitates measurement.
Description
Technical field
The utility model relates to a kind of fish length-measuring appliance, especially relates to the line measurement device of large-scale fish in a kind of ocean, because the fish body becomes curvilinear structures to cause measuring error, has improved the degree of accuracy of measuring to avoid.
Background technology
Sea survey is that various countries carry out a required important process of science investigation always, measure the life-span that to reflect fish to a certain extent by the profile of fish body and follow growth cycle, especially bigger fish of certain build, profile is measured can reflect life-span length and the growth cycle of this fish, whether ripe, can also be reflected in the status in the food chain, be that frequency faces extinction or quantity is a lot.Because be subjected to Effect of Environmental, and the bigger factor of marine fishes individuality, wanting accurately to finish surveying work, all can not be guaranteed from workload and on the time.
Existing length of fish body surveying instrument generally adopts the less ruler of tape measure, folding chi, scale etc.Though tape measure satisfies the linear measure longimetry requirement of the large-scale fish in ocean, be difficult to when measuring guarantee to accomplish line measurement that measurement result is a length of curve to a great extent.Folding chi also can't guarantee the accuracy of measuring though also can reach requirement on the range.Ruler can not guarantee degree of accuracy and needs easy to carry.
Summary of the invention
For solving the problems of the technologies described above, technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of fish length-measuring appliance is provided, and this measurement mechanism can be measured the fish straight length accurately, easily.
For solving the problems of the technologies described above, technical solutions of the utility model are achieved in that a kind of fish length-measuring appliance, comprise the main scale that is provided with scale reading, it is characterized in that: an end of described main scale vertically is provided with fixed bar, is arranged with sliding bar on main scale, and sliding bar can move on main scale, described sliding bar parallels with fixed bar, described fixed bar inboard is provided with inner groovy, and when sliding bar and fixed bar fitted, the scale reading of main scale was zero.
Described main scale is divided into two sections at least, and described main scale is spliced by each section.
Each of described main scale section forms by being threaded.
Described each section of main scale links together by clamping.
Described main scale is a hollow-core construction.
Described scale reading is located on the upper surface of main scale.
Described scale reading is located at upper surface bilateral of main scale.
The length of described fixed bar and sliding bar is greater than 30cm.
Described fixed bar and sliding bar are segmental structure, and each section is by being threaded.
The utility model beneficial effect, the utility model are measured macrura reevesii body one end and placed in the inner groovy of fixed bar inboard, and the other end is corresponding with sliding bar, by moving of sliding bar, measure fish length, and be simple in structure, and it is convenient to measure, and the accuracy of measurement height.
Because main scale adopts segmentation and hollow-core construction, make the utility model light, portable in addition, convenient measurement at sea.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, illustrated.
Description of drawings
Fig. 1 is the structural representation of the utility model fish length-measuring appliance.
Fig. 2 is the structural representation of the utility model main scale coupling part.
Fig. 3 is the structural representation of the utility model sliding bar.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, feature and effect thereof according to the fish length-measuring appliance that the utility model proposes, describe in detail as after.
As shown in Figure 1, a kind of fish length-measuring appliance of the utility model comprises fixed bar 1, main scale 2 and sliding bar 3.
Described fixed bar 1, main scale 2 and sliding bar 3 all adopt aluminum alloy materials to make.
The upper surface of described main scale 2 is evenly equipped with scale reading, and described fixed bar 1 places an end of main scale 2, and fixed bar 1 is vertical mutually with main scale 2, and described fixed bar 1 inboard is provided with inner groovy, can effectively prevent the problem that comes off that occurs because the fish surface is smooth.
As shown in Figure 3, described sliding bar 3 is socketed on the main scale 2, and can move on main scale 2, and sliding bar 3 contacts with main scale 2 near closely, can reduce measuring error.When fixed bar 1 and sliding bar 3 fitted, the scale reading of main scale 2 was zero.
Described main scale 2 is divided into two sections at least, and described main scale 2 is spliced by each section.Like this, can select length according to actual needs, both be convenient for measuring, be easy to carry again.
Each section of described main scale 2 can form by being threaded, the convenient installation, as shown in Figure 2.Also can link together, can certainly be connected by other modes by snap fit.
Described main scale 2 inside are hollow-core construction, make measurement mechanism light like this, are easy to carry.
The scale reading that the upper surface of described main scale 2 is provided with is bilateral setting, and never can making things convenient for, ipsilateral carries out reading.
The length of described fixed bar 1 and sliding bar 3 is greater than 30cm.Thereby guarantee that plump fish body also can be placed between fixed bar 1 and the sliding bar 3, measures.
Described fixed bar 1 also can adopt segmental structure with sliding bar 3, and each section is by being threaded.Can select length according to actual needs like this, to adapt to the fish body of different-thickness.
When the utility model uses, be example to measure tuna, the caudal furca place of large-scale fish such as fixed bar 1 and tuna is fixed, and sliding bar 3 slides into the kiss end of fish, and the reading that reads from main scale 2 upper surfaces is exactly the length that the fish body is measured in the lower end.The utility model measurement mechanism can carry out line measurement along the fish body vertebrae direction of growth.
The description of above-mentioned embodiment is the utility model preferred embodiment, but can not limit protection domain of the present utility model with this, and variation and the modification of being done in this way in every case is all within protection domain of the present utility model.
