Description

Aquatic larvae measurement console

technical field

The utility model relates to fishery field, particularly a kind of aquatic organism larvae measurement console.

Background technique

In the process of proliferation and release and fishery production, the measurement of aquatic organism specifications is to judge whether it meets the release standard or one of the main evaluation criteria for reaching production requirements. At present, fishery workers often use ordinary rulers or vernier calipers to measure, but the larvae of fish, shrimp and crabs are small in size and difficult to maintain a static state, which makes the measurement difficult, time-consuming and labor-intensive and prone to measurement errors. The work often needs to be carried out in places such as the seaside, ponds or farms, and the simple operating space will also increase the difficulty of measurement. These all have an impact on the accuracy of the measurement data.

SUMMARY OF THE INVENTION

The utility model is in order to solve the above-mentioned deficiencies existing in the prior art, proposes a kind of operation difficulty that can reduce aquatic organism larvae measurement, improves the aquatic organism larvae measurement console of accuracy and measurement efficiency.

The technical solution of the present utility model is: a kind of aquatic organism larvae measuring console, it is characterized in that: described console comprises measuring board 1, on measuring board 1, is provided with track 2 distributed along its length direction , A first support rod 4 is hinged on the slider 3 slidably connected with the track 2, the top end of the first support rod 4 is hinged with the second support rod 5 through the rotating shaft, and the top end of the second support rod 5 is connected by a universal joint 6 There is a telescopic frame 7, the end of the telescopic frame 7 is connected with a convex lens 9 through a fixed head 8, and a scale 10 is also provided on the upper surface of the measuring plate 1, and the scale 10 is composed of two mutual It consists of vertical tick marks.

Compared with the prior art, the present utility model has the following advantages:

The aquatic organism larvae measurement console of this structure provides a work surface with a scale, and a movable magnifying glass stand is arranged on the work surface, so that the process of measuring aquatic organisms can be more convenient. It is simple and fast, and at the same time, it can ensure the accuracy of the measurement results, which can greatly improve the work efficiency. And its manufacturing process is simple and the manufacturing cost is low, so it can be said that it has many advantages, and is especially suitable for popularization and application in this field, and its market prospect is very broad.

detailed description

Embodiment Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be described. As shown in Figure 1: an aquatic organism larvae measurement operation table, including a measurement board 1, the measurement board 1 can be made of polyethylene material, on the measurement board 1 is provided with a track 2 distributed along its length direction, and this The track 2 is slidably connected with a slider 3, and a first support rod 4 is hingedly arranged 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, and is hinged on the second support rod 5. The top end 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, and a scale 10 is provided on the upper surface of the measuring plate 1, and the scale 10 consists of two tick marks that are perpendicular to each other.

The working process of the aquatic organism larvae measurement console of the embodiment of the present utility model is as follows: the aquatic organism larvae that need to be measured are placed on the measuring plate 1, and the convex lens 9 is moved to allow it to move to the top of the organism larvae. Observe the biological larvae through the convex lens 9, and record the corresponding size of the biological larvae on the scale 10, that is, a measurement operation is completed; With the existence of the universal joint 6, the telescopic frame 7 can swing relative to the second support rod 5, and at the same time, the telescopic frame 7 can also drive the convex lens 9 to perform telescopic action, and all the above-mentioned mechanisms can also slide along the track 2 together with the slider 3. , the structure of the above actions 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.
