Description

A device for measuring the volume of aquatic organisms

Technical field

The invention relates to the field of cultivation and research of aquatic organisms, in particular to a device for measuring the volume of aquatic organisms.

Background technique

In recent years, the country has paid more and more attention to the diversity of marine biological resources, and it is often necessary to conduct basic biological surveys and analyzes of biological resources in some sea areas, which includes the measurement of the volume of aquatic organisms. Since most aquatic products have irregular external shapes, they cannot be measured directly and accurately. The drainage method is usually used to measure the volume of aquatic products: that is, a container filled with water is used with a measuring cylinder or measuring cup.

However, in actual operation, it is difficult to transfer the water overflowing from the container to the measuring cylinder or measuring cup completely and accurately, resulting in inaccurate measurement results. Therefore, a method or device that can solve the above problems is now needed.

Contents of the invention

In order to solve the above-mentioned deficiencies in the prior art, the present invention proposes a device with a simple structure, ingenious design, and reasonable layout, which can quickly and conveniently measure the volume of aquatic organisms, and can effectively ensure accurate measurement results.

The technical solution of the present invention is: a device for measuring the volume of aquatic organisms, which is characterized in that: the device includes a workbench 1, a measuring container 2 is provided on the workbench 1, and a measuring network is provided in the measuring container 2 Frame 3, the upper part of the measuring container 2 is provided with an obliquely distributed drainage pipe 4. The device also includes a measuring cylinder 5. The opening at the top of the measuring cylinder 5 is located below the outlet end of the drainage pipe 4. The drainage pipe 4 is The outlet end is relatively low, and the inclination angle of the drainage pipe 4 is 20-30°.

The measurement network frame 3 includes a frame body 6 and a plurality of sub-network frames 7. The sub-network frame 7 is hung on the frame body 6. When all the sub-network frames 7 are connected to the frame body 6, these sub-network frames 7 are connected to the frame body 6. The screen frames 7 are evenly distributed in the circumferential direction. Hooks 8 are provided at the top edge of the frame body 6. The frame body 6 is suspended in the measurement container 2 through the hooks 8.

Compared with the prior art, the present invention has the following advantages:

This structural form of device for measuring the volume of aquatic organisms has a simple structure, ingenious design and reasonable layout. In view of various problems existing in the traditional aquatic organism volume measurement process, a special structure is designed, which can conveniently Guide all overflowing water into the measuring cylinder, which can improve work efficiency on the one hand, and ensure the accuracy of measurement on the other hand; the measurement network frame used to place aquatic products contains multiple sub-network frames, and each sub-network frame The aquatic products to be measured can be put in, and the volumes of multiple aquatic products can be measured at one time; and the manufacturing process of this device is simple and the manufacturing cost is low, so it can be said that it has many advantages and is especially suitable for use in If it is promoted and applied in this field, its market prospect is very broad.

Detailed ways

Specific embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in Figure 1 and Figure 2: a device for measuring the volume of aquatic organisms, which includes a workbench 1 as a basis. A measuring container 2 is provided on this workbench 1, and a measuring mesh frame 3 is provided in the measuring container 2. , the upper part of the measuring container 2 is provided with an obliquely distributed drainage pipe 4. The device also includes a measuring cylinder 5. The opening at the top of the measuring cylinder 5 is located below the outlet end of the drainage pipe 4. The outlet end of the drainage pipe 4 Relatively low, and the inclination angle of the drainage pipe 4 is 20-30°,

The measurement network frame 3 includes a frame body 6 and a plurality of sub-network frames 7. The sub-network frame 7 is hung on the frame body 6. When all the sub-network frames 7 are connected to the frame body 6, these sub-network frames 7 are connected to the frame body 6. The screen frames 7 are evenly distributed in the circumferential direction. Hooks 8 are provided at the top edge of the frame body 6. The frame body 6 is suspended in the measurement container 2 through the hooks 8.

The working process of the device for measuring the volume of aquatic organisms in the embodiment of the present invention is as follows: first, hang the empty measuring screen frame 3 in the measuring container 2 using the hook 8 (the hook 8 is hung at the top edge of the measuring container 2), and then to the measuring container 2. Pour the water for measurement into the container 2 and stop when the water level reaches a position flush with the inlet end of the drainage pipe 4. Then use tweezers to clamp the water-generating object and slowly place it into a certain subnet frame 7. After the operation is completed Close the opening of the subnet frame 7. The netting on the subnet frame 7 will prevent the measured water products from escaping. During this process, a part of the water body will overflow through the drainage pipe 4. This part of the water body will overflow along the inclined drainage pipe 4. It flows into the measuring cylinder 5, and by observing the scale corresponding to the water level in the measuring cylinder 5, the volume of the currently measured water product can be obtained;

If you need to continue to measure the volume of other aquatic products, you can also repeat the above operation, use tweezers to clamp the second aquatic product and slowly place it into an empty subnet frame 7. After the operation is completed, close the subnet frame 7 After the operation is completed, observe the scale corresponding to the water level in the measuring cylinder, and subtract the scale of the previous operation from the current scale, which is the volume of the second water-generated product;

By analogy, the volume of multiple aquatic organisms can be measured continuously.
