Description

Technical Field

[0001] The utility model relates to the technical field of fish biology, in particular to a measuring device for the biological morphological characteristics of fish. Background Technique

[0002] Fish are the oldest vertebrates. They are prone to accumulating heavy metals. The offspring of some hybrids with different chromosome numbers are still fertile. They inhabit almost all aquatic environments on the earth, from freshwater lakes and rivers to saltwater seas and oceans.

[0003] The body length of fish is an important biological characteristic. When measuring the specific size of fish at present, the fish to be measured needs to be fished out of the water for measurement. However, during this process, the fish will keep swinging when it leaves the water, which will cause deviation in measurement and affect the health of the fish. Moreover, if the fish is forcibly fixed for measurement, when the fish struggles and swings greatly, it will cause greater harm to the fish itself and affect the survival life of the fish.

[0004] Therefore, the technical personnel in this field have provided a measuring device for the biological morphological characteristics of fish to solve the problems put forward in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to provide a measuring device for the biological morphological characteristics of fish to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A measuring device for the biological morphological characteristics of fish, including a bottom plate, a limiting mechanism and a measuring mechanism. A weighing scale is fixedly connected to the center position of the upper end surface of the bottom plate, and a measuring box is fixedly connected to the upper end of the weighing scale. One end inside the upper end surface of the measuring box is rotatably connected with a first bidirectional lead screw. Both the left and right ends of the first bidirectional lead screw are threadedly connected with threaded connection blocks. The threaded connection blocks are slidably connected with the inner wall of the measuring box. One end of the threaded connection block close to the measuring box is fixedly connected with a first moving plate, and the other end of the threaded connection block close to the measuring box is fixedly connected with a second moving plate. Both the first moving plate and the second moving plate are slidably connected with the measuring box. A limiting mechanism and a measuring mechanism are arranged on the upper ends of the first moving plate and the second moving plate. One side wall of the measuring box is rotatably connected with a rocker, and the power end of the rocker penetrates through the measuring box and is fixedly connected with the first bidirectional lead screw.

[0008] As a further solution of the utility model: A plurality of first damping springs are fixedly connected to the outer side wall of the first moving plate, the other ends of the plurality of first damping springs are fixedly connected to a first measuring plate, a second bidirectional lead screw is rotatably connected to the inside of one end of the first measuring plate, threaded sleeves are threadedly connected to the outer side walls of the upper and lower ends of the second bidirectional lead screw, the threaded sleeves are slidably connected to the first measuring plate, a slide bar is fixedly connected to the inside of the other end of the first measuring plate, slide sleeves are slidably connected to the upper and lower ends of the outer side wall of the slide bar, and centering limit plates are fixedly connected to the adjacent slide sleeves and the upper ends of the threaded sleeves.

[0009] As a further solution of the utility model: Shrinkage plates are slidably connected to the inside of the centering limit plates, and a plurality of extrusion springs are fixedly connected between the shrinkage plates and the centering limit plates. A plurality of second damping springs are fixedly connected to the outer side wall of the second moving plate, the other ends of the plurality of second damping springs are fixedly connected to a second measuring plate, and a plurality of water flow holes are formed in the first moving plate, the second moving plate, the first measuring plate and the second measuring plate.

[0010] As a further solution of the utility model: A width measuring ruler is fixedly connected to one end of the upper end surface of the measuring box away from the first bidirectional lead screw, a length measuring ruler is fixedly connected to one side of the upper end surface of the measuring box, and a pair of symmetrically arranged height measuring rulers are fixedly connected to the upper end surface of the second measuring plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Due to the limited position mechanism, by adjusting the positions of the moving plate and the centering limit plate, it can adapt to fish of different sizes, be more flexible when dealing with fish of different sizes. During the measurement process, damping springs are equipped, which can effectively reduce the risk of fish injury. The damping springs can absorb vibrations and impacts, protect the fish body from damage, reserve space for the fish when it swings, and play a certain limiting effect to assist the staff in observing the specific size. Due to the measurement mechanism, after being limited by the limiting mechanism, the length, width and height of the fish can be measured respectively by using three measuring rulers, the precise size of the fish can be obtained, the measurement error can be reduced as much as possible, and the safety of the fish during detection can be ensured. Moreover, the weighing scale can weigh the weight of the fish to ensure that the fish remains in the water during the measurement work. Description of the Drawings
