Description

Aquatic larvae measuring console

Technical field

[0001] The utility model relates to the field of fisheries, in particular to a measuring operation table for aquatic larvae.

Background technique

[0002] In the process of multiplication and release and fishery production, the measurement of the specifications of aquatic organisms is one of the main criteria for judging whether it meets the release standards or whether it meets the production requirements. At present, fishery workers often use ordinary rulers or vernier calipers to measure, but the individual size of fish, shrimp and crab larvae is small and it is not easy to keep still, which makes the measurement difficult, time-consuming and laborious, and easy to produce measurement errors; in addition, measurement Work often needs to be carried out in places such as seaside, pond or breeding farm, and the simple operation space will also increase the difficulty of measurement. These will have an impact on the accuracy of the measurement data.

Summary of the invention

[0003] In order to solve the above-mentioned shortcomings in the prior art, the present utility model proposes an aquatic larval measuring operation table that can reduce the operational difficulty of measuring aquatic larvae and improve the accuracy and measurement efficiency.

[0004] The technical solution of the present utility model is: an aquatic larvae measuring operation table, characterized in that: the operation table includes a measurement board 1, on the measurement board 1 is provided with tracks 2 distributed along its length direction , A first strut 4 is hinged on the sliding block 3 slidably connected to the track 2. The top of the first strut 4 is hinged with the second strut 5 through a rotating shaft, and the top of the second strut 5 is connected by a universal joint 6. There is a telescopic frame 7, and the end of the telescopic frame 7 is connected with a convex lens 9 through a fixed head 8. Composition of vertical tick marks.

[0005] Compared with the prior art, the utility model has the following advantages:

[0006] The aquatic larvae measuring operation table of this structure provides a working table with a scale, and a movable magnifying glass stand is set on the working table, so that the process of measuring aquatic organisms can be improved. It is simple and fast, and at the same time it can ensure the accuracy of the measurement results, which can greatly improve work efficiency. Moreover, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has a variety of advantages and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

Description of the drawings

[0007] FIG. 1 is a schematic structural diagram of an embodiment of the utility model.

Detailed ways

[0008] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. As shown in Figure 1: An aquatic organism larvae measuring operation table, including a measuring board 1, this measuring board 1 can be made of polyethylene material, the measuring board 1 is provided with a track 2 distributed along its length, and this The rail 2 is slidably connected with a slider 3, and a first support rod 4 is hinged on the slider 3. The top end of the first support rod 4 is hinged with the second support rod 5 through a rotating shaft. The top end of the telescopic frame 7 is connected to a telescopic frame 7 through a universal joint 6, and the end of the telescopic frame 7 is connected with a convex lens 9 through a fixed head 8. A scale 10 is provided on the upper surface of the measuring plate 1, and the scale 10 is composed of two vertical scale lines.

[0009] The working process of the aquatic larvae measuring operation table of the embodiment of the present invention is as follows: the aquatic larvae to be measured are placed on the measuring plate 1, and the convex lens 9 is moved to move to the upper side of the larvae, and the operator Observe the larvae through the convex lens 9 and record the corresponding size of the larvae on the scale 10, that is, a measurement operation has been completed; since the first pole 4 and the second pole 5 can swing relative to each other, With the existence of the universal joint 6, the telescopic frame 7 can swing relative to the second support rod 5. At the same time, the telescopic frame 7 can also drive the convex lens 9 to expand and contract. All the above-mentioned mechanisms can also slide along the rail 2 together with the slider 3 The above-mentioned action structure can realize the movement of the convex lens 9 in three directions, and ensure that the convex lens 9 can move to any position on the measuring plate 1 to measure the larvae of aquatic organisms.
