Description

Technical Field

[0001] The utility model relates to the technical field of fish egg research, in particular to a fish egg hardness detection device. Background Art

[0002] Egg hardness is an important indicator of the physical properties of fish eggs, referring to the firmness of the egg structure and its ability to resist external pressure. As a key biological characteristic, egg hardness is of great significance for evaluating the overall quality of fish eggs and the process of early embryonic development. Egg hardness and other physical properties of fish eggs, such as diameter, color, transparency, and buoyancy, are all important reference indicators for evaluating the quality of fish eggs. Studies have found that environmental factors (such as water pollution) can have a significant impact on the hardness of fish eggs. For example, after the marine medaka (a small marine model fish) was treated with water pollutants, the hardness of the eggs produced increased significantly, accompanied by a decrease in the embryonic hatching rate. This shows that egg hardness can be used as a basic indicator to reflect the interference of water pollution on the quality and development of fish eggs.

[0003] However, there is currently no device structure that can accurately and conveniently measure the hardness of fish eggs. The current method of determining the hardness of fish eggs is to manually press them, which is a qualitative analysis based on personal experience and cannot provide quantitative and accurate analysis. Current methods for measuring fish egg hardness have certain limitations, such as complex operation, insufficient accuracy, and difficulty in implementing batch testing. Therefore, there is an urgent need to innovate fish egg hardness testing devices and promote their widespread application. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The present application relates to a device for detecting the hardness of fish eggs. The device applies a squeezing force to the fish eggs, forcing the fish eggs to break, and records the pressure change from the beginning of applying the force to the fish eggs to the time when the fish eggs break, thereby being able to accurately obtain the hardness of the fish eggs. The overall operation is very simple, the accuracy of obtaining the fish egg hardness is extremely high, and the efficiency of fish egg hardness detection is greatly improved.

[0030] Specifically, such as Figures 1-2 As shown, the fish egg hardness detection device of the present application includes a fixed base 1, a placement plate 2, an extrusion structure and a pressure sensor. The fixed base 1 is the bearing foundation of the entire fish egg hardness detection device; the placement plate 2 is a flat plate fixed on the fixed base 1, and a placement hole 3 for placing fish eggs is provided on the placement plate 2. The placement hole 3 is a blind hole with an opening on one side, and the placement hole 3 has an opening on one side and a closed bottom on the other side. The fish eggs are placed in the placement hole 3, and the extrusion structure includes a pressure head 4. The pressure head 4 is a block structure corresponding to the placement hole 3 and can move axially along the placement hole 3 to extend into the placement hole 3 to squeeze the fish eggs. The pressure head 4 extends into the placement hole 3 along the axial direction of the placement hole 3 to squeeze the fish eggs in the placement hole 3; the pressure sensor is arranged on the pressure head 4 to monitor the extrusion force applied by the pressure head 4 to the fish eggs.

[0031] During actual operation: assemble the fish egg hardness testing device according to the above structure, turn on the power supply of the pressure sensor, check that the various functions of the pressure sensor are correct, clear historical data, and wait for the test to start; use a disposable straw to take a fish egg and place it on absorbent paper, blot the surface moisture of the fish egg, and place the fish egg in the central authorities of the placement hole 3 to be tested; drive the pressure head 4 to move axially along the placement hole 3 until the pressure head 4 enters the placement hole 3 and squeezes the fish egg, until the pressure head crushes the fish egg (but does not touch the placement hole 3 surface); record the pressure head 4 extrusion peak value monitored by the pressure sensor and be the hardness size of the fish egg, and store these data; remove the broken fish egg, wipe the placement hole 3 and the pressure head 4 with wiping paper to prevent residue from affecting the next detection; carry out the hardness test of the next fish egg according to the above process, carry out in sequence, until all fish egg hardness tests are completed; derive all stored data for the convenience of subsequent centralized processing and analysis of data; turn off the power supply of the pressure sensor, and place the instrument in a room temperature and dry environment for next use.

[0032] In some embodiments of the present application, the structure of the placement plate 2 is optimized. Specifically, Figures 1-2 As shown, the placement plate 2 of this embodiment is a side plate fixed vertically to the fixed base 1. The placement hole 3 is provided on one side of the placement plate 2, with the axial direction of the placement hole 3 being horizontal. The placement hole 3 is a horizontally arranged circular hole structure, so the corresponding pressure head 4 is also a cylindrical block structure of the same size as the placement hole 3. The pressure head 4 extends into the placement hole 3 in the horizontal direction, i.e., the axial direction of the placement hole 3.

[0033] In practical application, the placement holes 3 are not limited to being arranged horizontally. The placement plates 2 can also be arranged horizontally and the placement holes 3 can be arranged vertically, that is, the upper end of the placement holes 3 is open and the lower end is closed. In this case, the pressing head 4 is required to extend vertically into the placement holes 3. As long as the placement holes 3 are arranged axially, the fish eggs can be stably placed in the placement holes 3, and the pressing head 4 can extend axially into the placement holes 3 to squeeze the fish eggs.

[0034] In other embodiments of the present application, the present embodiment further optimizes the above-mentioned device structure. Specifically, Figures 1-2 As shown, this embodiment further includes a base 6, which is connected to the fixed base 1 and can slide along the axial direction of the placement hole 3. The pressure head 4 is provided on one side of the base 6 along the axial direction of the placement hole 3, and a push rod 7 is provided on the other side of the base 6 along the axial direction of the placement hole 3. The push rod 7 is convenient for the operator to hold. The operator holds the push rod 7 to drive the pressure head 4 to move axially along the placement hole 3 to complete the squeezing of the fish eggs.

[0035] Specifically, a slide groove 8 is provided on the fixed base 1, and the extension direction of the slide groove 8 is parallel to the axial direction of the placement hole 3. The base 6 is slidably connected in the slide groove 8. The slide groove 8 limits the base 6 to move only in the axial direction of the placement hole 3, which greatly facilitates the operator and can quickly complete the operation without having to align the pressure head 4 and the placement hole 3.

[0036] In addition, the extrusion structure of this embodiment further includes a pressure rod 5, which is a rod-shaped structure arranged coaxially with the placement hole 3. The pressure head 4 is detachably connected to the end of the pressure rod 5 facing the placement hole 3. The pressure head 4 and the pressure rod 5 are detachable structures. This makes it easy to remove the pressure head 4 for separate cleaning after the extrusion test is completed, avoiding the tedious need to disassemble the entire device for cleaning.

[0037] As shown in the figure, this embodiment is also provided with a display screen 9 for displaying the pressure value of the pressure sensor and a USB interface for data transmission on the base 6. There are also a storage button for storing recorded data and a reset button for zeroing, which are actually switch, save and reset buttons.

[0038] When actually testing the hardness of fish eggs: install the base 6 on the chute 8 of the fixed base 1, arrange the pressure rod 5, the pressure head 4 and the pressure sensor and other structures, turn on the power of the pressure sensor, check that all functions of the pressure sensor are correct, clear the historical data, and wait for the test to start;

[0039] Use a disposable straw to take a fish egg and place it on absorbent paper, dry the surface moisture of the fish egg, and place the fish egg in the center of the placement hole 3 to be tested;

[0040] The push rod 7 drives the base 6 to move along the chute 8 toward the side of the placement hole 3 until the pressure head 4 extends into the placement hole 3 and crushes the fish eggs; the current pressure peak value displayed by the display screen 9 is the hardness of the fish eggs, and the current peak value is stored in the instrument through the storage button on the base 6;

[0041] Remove the broken fish eggs and wipe the placement hole 3 and the pressure head 4 with a wipe to prevent the residue from affecting the next test;

[0042] After clearing the current data by the reset button on the base 6, take another fish egg for testing with a disposable straw, and repeat the above steps until the hardness test of all fish eggs is completed;

[0043] Check all the data stored by the pressure sensor during this test and export the data to a computer via the USB interface to facilitate subsequent centralized data processing and analysis;

[0044] Turn off the power of the pressure sensor and place the instrument in a dry environment at room temperature for next use.
