Description

Technical Field

[0001] This utility model relates to aquatic parameter detection devices, and more particularly to a multi-parameter measurement device for eels. Background Technology

[0002] Eels are an important subject of fish research, and their body length is a crucial indicator of swimming ability. In addition, weight and height are two essential experimental measurement parameters. In most cases, researchers measure body length and weight by holding the fish down and using a ruler. This often results in the fish struggling and sometimes even falling off the testing table. Furthermore, compared to other fish, eels are more difficult to measure accurately. Therefore, traditional measurement methods are not only inconvenient and inaccurate, but can also cause excessive behavior and harm to the fish. Summary of the Invention

[0003] To address the problems of inconvenience, inaccuracy, and potential for excessive behavior in fish caused by traditional measurement methods in the prior art, this utility model provides a multi-parameter measurement device for eels, including a measurement box and a water tank. The water tank is installed on the side wall of the measurement box, and a flow hole is opened at the bottom of the side of the measurement box near the water tank. A measurement base plate is placed inside the measurement box, and a measurement pressure plate is placed on the measurement base plate. A movable slide rod is fixedly installed on the top of the measurement pressure plate.

[0004] In a preferred embodiment, both the measuring box and the water tank are lidless structures.

[0005] In a preferred embodiment, the top of the measuring box is provided with a first cover plate and a second cover plate.

[0006] In a preferred embodiment, the first cover plate and the second cover plate are connected to the side wall of the measuring box via a hinged seat.

[0007] In a preferred embodiment, at least three columns are fixedly installed at the inner corners of the measuring box, and the measuring base plate is placed on top of the columns.

[0008] In a preferred embodiment, the side wall of the measuring box is provided with a height measuring ruler and a length measuring ruler.

[0009] In a preferred embodiment, a drain pipe is provided at the bottom of the side wall of the water tank, and a ball valve is provided on the drain pipe.

[0010] In a preferred embodiment, the overall density of the measuring base plate is less than that of water, for example, by using lightweight plastic or a hollow structure.

[0011] In a preferred embodiment, the measuring box is made of a transparent material, such as PC board or glass.

[0012] The beneficial effects of this utility model are:

[0013] (1) Reduced direct contact between people during measurement. The fish was fixed by adjusting the height of the base plate and the extension of the pressure plate, thus avoiding injury to the fish caused by jumping during measurement.

[0014] (2) By adjusting the height of the base plate and the extension of the pressure plate, the fish can be fixed, and the body length and height parameters of the curved eel can be accurately measured;

[0015] (3) Since the mass of the device itself can be measured, after measuring the length and height of the fish, the fish and the entire device can be placed on the weighing device. The difference between the measured weight and the weight of the device is the weight of the fish, thereby realizing the measurement of the eel's weight parameters. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-5 The eel multi-parameter measuring device shown includes a measuring box 1 and a water tank 2. The water tank 2 is installed on the side wall of the measuring box 1. A flow hole 12 is opened at the bottom of the side of the measuring box 1 near the water tank 2. A measuring base plate 5 is placed inside the measuring box 1. A measuring pressure plate 7 is placed on the measuring base plate 5. A movable slide rod 8 is fixedly installed on the top of the measuring pressure plate 7.

[0025] Furthermore, both the measuring box 1 and the water tank 2 are lidless box structures.

[0026] Furthermore, the top of the measuring box 1 is provided with a first cover plate 3 and a second cover plate 4.

[0027] Furthermore, the first cover plate 3 and the second cover plate 4 are connected to the side wall of the measuring box 1 via a hinge seat 6.

[0028] Furthermore, at least three columns 11 are fixedly installed in the inner corner of the measuring box 1, and the measuring base plate 5 is placed on top of the columns 11.

[0029] Furthermore, the side wall of the measuring box 1 is provided with a height measuring ruler 9 and a length measuring ruler 10.

[0030] Furthermore, a drain pipe 13 is provided at the bottom of the side wall of the water tank 2, and a ball valve 14 is provided on the drain pipe 13.

[0031] Furthermore, the overall density of the measuring base plate 5 is less than the density of water, which facilitates the measuring base plate 5 rising or falling with the water level.

[0032] Furthermore, the measuring box 1 is made of acrylic sheet.

[0033] The process of using the above-mentioned device is as follows: Open the first cover plate 3 and the second cover plate 4, place the fish to be tested on the measuring base plate 5, close the first cover plate 3 and the second cover plate 4, fill the water tank 2 with water, and as the water level rises, the measuring base plate 5 rises simultaneously with the buoyancy. After rising to a suitable height for convenient measurement, stop filling the water, pull the sliding rod 8 to move the measuring pressure plate 7 so that the fish to be tested is close to the side wall of the measuring box 1. Then, read the height and length of the fish through the height measuring ruler 9 and the length measuring ruler 10. When weighing, place the entire device on a mass scale for weighing, then take out the fish and measure the weight of the device again. Finally, calculate the difference between the previous and subsequent measurements to obtain the weight of the fish. After the above operations are completed, open the ball valve 14 and drain the water in the measuring box 1 and the water tank 2 through the drain pipe 13 to clean the device and keep it clean for recycling.
