Description

Technical Field

[0001] This utility model relates to the field of aquatic organism measurement technology, and in particular to a measuring device for measuring the fatness of shellfish based on liquid volume. Background Technology

[0002] In shellfish aquaculture, plumpness is an important indicator for measuring the growth status and meat fullness of shellfish. For bivalve shellfish, plumpness index is commonly used to indicate the fatness of the meat. The plumpness index is of guiding significance for determining the appropriate harvesting time and predicting egg collection in the aquaculture process, and it is also an important breeding indicator. At the same time, shellfish with high plumpness have plump meat, rich juice, better taste, and higher market value. Therefore, accurately measuring the plumpness of shellfish is of great significance for guiding aquaculture practices and improving product quality.

[0003] The existing methods for measuring shellfish plumpness are mainly sensory methods. Sensory evaluation relies on the subjective judgment of the evaluator on the plumpness of the shellfish meat, which makes it difficult to guarantee the accuracy and consistency of the measurement results. Most evaluators obtain the plumpness index by the ratio of the mass of the shellfish soft tissue to the overall mass or volume. However, measuring the dry weight of the soft tissue is cumbersome and differs from the plumpness shown in live shellfish. Furthermore, it is inconsistent with the meaning of plumpness in production.

[0004] However, existing methods for measuring shellfish conditionability suffer from insufficient accuracy, poor consistency, and cumbersome operation. This paper proposes a precise measurement device and method based on liquid volume measurement to improve accuracy and precision, reduce the influence of human factors, ensure the objectivity and consistency of measurement results, standardize the operation process, and monitor the growth status and conditionability changes of shellfish in real time. This provides accurate data support for shellfish-related research and demonstrates broad adaptability and application prospects. Therefore, a measurement device based on liquid volume measurement of shellfish conditionability is proposed to address the aforementioned problems. Utility Model Content

[0008] The measuring component includes a weighing tray, the bottom of which is fixedly connected to the inner wall of the receiving groove. A measuring cup is placed above the weighing tray, and a drainage component is provided on the side wall of the measuring cup. A flow collector is provided on the top of the measuring cup, and a storage bucket is provided on the top of the flow collector.

Each flow guide groove has a water outlet hole inside. A fixing component is provided on the outer wall of the storage bucket and the flow collector to fix the position of the storage bucket and the flow collector.

[0010] The drainage assembly includes an electrically controlled valve, the side wall of which is fixedly connected to the bottom of the outer wall of the measuring cup. A flexible hose is fixedly connected to the output end of the measuring cup. A wastewater tank is provided inside the base. One end of the flexible hose is fixedly connected to the top of the wastewater tank. A water outlet valve is fixedly connected to the side wall of the wastewater tank and is located on the outer wall of the base.

[0011] As a further description of the above technical solution:

[0012] Multiple control buttons are fixedly connected to the side wall of the base, and the control buttons are distributed in an array on the side wall of the base.

[0013] As a further description of the above technical solution:

[0014] The fixing assembly includes left and right symmetrical fixing plates, the side walls of which are fixedly connected to the inner wall of the bearing box, and the other side wall of which is fixedly connected to a fixing block.

[0015] As a further description of the above technical solution:

[0016] Both the fixing plate and the fixing block are slidably connected to a connecting rod. One end of each connecting rod is fixedly connected to a pull ring, and the other end of each connecting rod is fixedly connected to a U-shaped clamp.

[0017] As a further description of the above technical solution:

[0018] Each connecting rod has a reset plate fixedly connected to its outer wall, and the outer wall of each reset plate is slidably connected inside the fixed block.

[0019] As a further description of the above technical solution:

[0020] Each connecting rod is fitted with a limiting spring on its outer wall. One end of each limiting spring is fixedly connected to the side wall of the reset plate, and the other end of each limiting spring is fixedly connected to the inner wall of the fixing block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, first, add sufficient water to the water level line in the storage bucket, then place the shellfish to be tested inside. The water flows through the outlet and guide channel into the concentrator and then into the measuring cup. Use a weighing tray to measure the total volume data M1. Dissect the shellfish, keep the empty shell, and place it in the storage bucket to measure the shell volume M2. Place the shellfish meat in the storage bucket to measure the soft body volume M3. Calculate the shell cavity volume M0 (M0 = M1 - M2) by measuring the mass of an equal volume of water. Based on C... F = (M3 / M0) × 100% to calculate body fat percentage C F This solves the problems of cumbersome measurement and large errors in traditional methods, and improves detection efficiency and accuracy.

[0023] 2. In this utility model, before using the shellfish plumpness measuring device, the operator manually pulls the pull ring outward. The displacement of the pull ring causes the connecting rod and U-shaped clamp to move outward, and the reset plate on the outer wall of the connecting rod also moves accordingly, causing the limiting spring to be compressed. Then, the concentrator is placed between the U-shaped clamps, the pull ring is released, and the reaction force of the limiting spring pushes the reset plate to move towards the center, causing the U-shaped clamp to clamp the concentrator. Repeating this operation to fix the container quickly completes the device assembly, solving the problem of cumbersome device assembly and improving work efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 The present invention provides an embodiment of a measuring device for measuring the fatness of shellfish based on liquid volume, comprising a base 1. The main function of the base 1 is to provide stable support for the entire measuring device. The top of the base 1 is provided with a receiving groove 4, which provides installation space for components such as the carrier box 2 and the weighing tray 5, and also provides a certain degree of protection to prevent these components from being damaged by external collisions. The carrier box 2 is fixedly connected to the top of the receiving groove 4. The function of the carrier box 2 is to accommodate the measuring components and provide a relatively independent space for the measurement process, reducing the interference of external factors on the measurement results. The measuring components are installed inside the carrier box 2.

[0032] The measuring assembly includes a weighing tray 5, which weighs the measuring cup 10 and the liquid within it. By measuring the weight data under different conditions, it provides a basis for subsequent calculations of the shellfish's volume and fullness. The bottom of the weighing tray 5 is fixedly connected to the inner wall of the receiving tank 4. The measuring cup 10, made of glass, is positioned above the weighing tray 5 to receive water flowing out from the collector 9. The outer wall of the measuring cup 10 is marked with graduations for easy observation of the water level. The function of the measuring cup 10 is to collect water flowing out from the storage bucket 6 so that its weight can be measured via the weighing tray 5, thereby calculating the shellfish's volume. A drainage assembly is provided on the side wall of the measuring cup 10, and the collector 9 is located on the top of the measuring cup 10. 9 is made of plastic and is designed to collect water flowing from the guide channel 7 into the measuring cup 10. A storage bucket 6, made of glass, is located on top of the collector 9. A water level line is marked 3cm from the bucket opening on the bucket wall. The storage bucket 6 is used to hold the shellfish to be tested and water. During the measurement process, the shellfish will expel a certain volume of water after being placed in the storage bucket 6. The volume of the shellfish is indirectly measured by measuring the volume of the expelled water. Multiple guide channels 7 are formed on the outer wall of the storage bucket 6 to guide water flowing from the outlet hole 8 into the collector 9. The guide channels 7 are circumferentially distributed at 2cm intervals on the outer wall of the storage bucket 6. Each guide channel 7 has an outlet hole 8, which is formed by drilling within the guide channel 7. The small hole in the container 6 allows water to drain smoothly after shellfish are placed inside. A fixing assembly is provided on the outer wall of the container 6 and the collector 9 to secure their positions. The drainage assembly includes an electrically controlled valve 19, located 2cm below the bottom of the measuring cup 10. Its function is to control the drainage of water from the measuring cup 10 into the wastewater tank 21 after each measurement. The side wall of the electrically controlled valve 19 is fixedly connected to the bottom of the outer wall of the measuring cup 10. A flexible hose 20 is fixedly connected to the output end of the measuring cup 10, connecting the electrically controlled valve 19 and the wastewater tank 21. The wastewater tank 21 is located inside the base 1 and is used for temporary storage of the water from the measuring cup 10. One end of the water hose 20 is fixedly connected to the top of the wastewater tank 21. A water outlet valve 11 is fixedly connected to the side wall of the wastewater tank 21. The water outlet valve 11 is located on the outer wall of the base 1. The function of the water outlet valve 11 is to control the discharge of water in the wastewater tank 21 after the measurement is completed, so as to facilitate the next measurement. A wheel is set on its top. After the electronic control function fails, the staff can manually open the valve to drain water through the wheel. Multiple control buttons 3 are fixedly connected to the side wall of the base 1. The control buttons 3 are switch, zeroing, storage, and water discharge. Their function is to control the start, stop, and data recording of the weighing tray 5 and to control the operation of the electronic control valve 19 to discharge water, so as to facilitate the staff to perform the measurement. The control buttons 3 are distributed in an array on the side wall of the base 1.

[0033] Specifically, during the measurement operation, the staff first adds sufficient water to the storage tank 6 until the water level reaches the designated line. Then, the staff places the shellfish to be measured into the storage tank 6. During this process, the shellfish is immersed in the water inside the storage tank 6. Because the shellfish occupies a certain amount of space, the water inside the storage tank 6 is squeezed out through the water outlet 8. After flowing out of the water outlet 8, the water flows downwards along the inner wall of the guide channel 7 and finally flows into the concentrator 9. The concentrator 9 gathers the water flowing in from each guide channel 7. Then, under the action of gravity, the water flows downwards into the measuring cup 10. As water continuously flows into the measuring cup 10, the staff presses the control button 3 on the side wall of the base 1 to activate the measurement function of the weighing tray 5 and records the total volume data M1 at this time. The data will be stored on the display screen. At this time, the electrically controlled valve 19 opens the measuring cup 10. Water is discharged into wastewater tank 21 through hose 20. Then, the staff removes the shellfish from storage bucket 6 for dissection, retaining only the empty shells. Water is then replenished to the water level line in storage bucket 6, and the empty shells are placed back in. The water level in storage bucket 6 rises again, and water is discharged through outlet 8, flowing along guide channel 7 and concentrator 9 into measuring cup 10. The staff presses control button 3 again to record the shell volume data M2. Electrically controlled valve 19 discharges water back into wastewater tank 21. Next, the staff places the soft tissue, i.e., the shelled meat, into storage bucket 6. The staff measures and records the soft tissue volume data M3. Finally, the staff automatically calculates the shell cavity volume M0 of the shellfish using the control components inside the base 1, i.e., M0 = M1 - M2. Then, based on the ratio of shell cavity volume M0 to soft tissue volume M3, i.e., C... F = (M3 / M0) × 100%, automatically calculates the body condition C of shellfish. F This allows for the accurate determination of the shell cavity volume and plumpness index of the shellfish being tested, achieving the effect of rapid detection of shellfish plumpness. After the entire measurement process is completed, the staff can open the water outlet valve 11 on the side wall of the base 1 to discharge the water in the wastewater tank 21, preparing for the next measurement.

[0034] Reference Figure 3The fixing assembly includes symmetrical fixing plates 12 on both sides. The function of the fixing plates 12 is to provide the installation base and support for the entire fixing assembly. The side walls of the fixing plates 12 are fixedly connected to the inner wall of the bearing box 2. The other side wall of the fixing plates 12 is fixedly connected to fixing blocks 13. The fixing blocks 13 have sliding channels that are adapted to the connecting rods 14, providing guidance and limiting for the sliding of the connecting rods 14. The connecting rods 14 are slidably connected inside the fixing plates 12 and fixing blocks 13. The function of the connecting rods 14 is to transmit force and drive the movement of other components. One end of the connecting rods 14 is fixedly connected to a pull ring 15. Pulling the pull ring 15 can cause the connecting rods 14 to move. The other end of the connecting rods 14 is fixedly connected to a U-shaped clamp 18. The U-shaped clamp 18 is made of metal. The function of the U-shaped clamp 18 is... The clamping mechanism secures the concentrator 9 and the storage bin 6 in a suitable position to prevent shaking or displacement during measurement and ensure measurement accuracy. A reset plate 16 is fixedly connected to the outer wall of the connecting rod 14. Its function is to cooperate with the limiting spring 17 to achieve the reset function of the connecting rod 14. The outer wall of the reset plate 16 is slidably connected inside the fixing block 13. A limiting spring 17 is sleeved on the outer wall of the connecting rod 14. Its function is to be compressed when the connecting rod 14 is displaced outwards, storing elastic potential energy. When the external force disappears, the elastic potential energy is released, pushing the reset plate 16 and the connecting rod 14 to reset, thereby allowing the U-shaped clamp 18 to clamp the concentrator 9 or the storage bin 6. One end of the limiting spring 17 is fixedly connected to the side wall of the reset plate 16, and the other end is fixedly connected to the inner wall of the fixing block 13.

[0035] Specifically, before using the shellfish plumpness measuring device, the operator first applies a pulling force outward, pulling the pull ring 15. The displacement of the pull ring 15 causes the connecting rod 14 to move outward synchronously. The connecting rod 14 slides outward within the sliding channel inside the fixed plate 12 and the fixed block 13. The outward displacement of the connecting rod 14 further causes the U-shaped clamp 18 fixedly connected to its other end to move outward in the horizontal direction, increasing the distance between the U-shaped clamps 18. At the same time, the reset plate 16 fixedly connected to the outer wall of the connecting rod 14 also moves outward synchronously with the displacement of the connecting rod 14. The displacement of the reset plate 16 causes the limiting spring 17 on one side to be compressed. Under the push of the reset plate 16, the limiting spring 17 is gradually compressed, and the elastic potential energy continuously increases. Then, the operator places the concentrator 9 between the U-shaped clamps 18. Then, the operator releases the pull ring 15. At this time, the external force acting on the pull ring 15... As the force disappears, the limiting spring 17 begins to release its elastic potential energy, generating a restoring reaction force that pushes the reset plate 16 to move towards the center. Under the action of the limiting spring 17, the reset plate 16 slides towards the center along the horizontal direction within the sliding channel inside the fixing block 13, causing the connecting rod 14 to also move towards the center. The movement of the connecting rod 14 towards the center further causes the U-shaped clamp 18 to move towards the outer wall of the concentrator 9. Finally, the U-shaped clamp 18 tightly clamps the concentrator 9, fixing it in the appropriate position. Then, the operator pulls the pull ring 15 again in the same way, causing the U-shaped clamp 18 to move outward and placing the storage bucket 6 between the U-shaped clamps 18. Then, the pull ring 15 is released, and under the action of the limiting spring 17, the U-shaped clamp 18 moves towards the outer wall of the storage bucket 6 again and clamps it, completing the fixation of the storage bucket 6. Through this operation, the concentrator 9 and the storage bucket 6 are quickly fixed, thus achieving the effect of quickly assembling the measuring device.

[0036] Working principle: Before using the shellfish plumpness measuring device, the operator first manually pulls the pull ring 15 outward. The displacement of the pull ring 15 causes the connecting rod 14 to move outward synchronously, which in turn causes the U-shaped clamp 18 to move outward. At the same time, the reset plate 16 on the outer wall of the connecting rod 14 also moves. The displacement of the reset plate 16 causes the limiting spring 17 on one side to be compressed. Then, the operator places the concentrator 9 between the U-shaped clamps 18, and then releases the pull ring 15. Under the restoring reaction force of the limiting spring 17, the reset plate 16 is pushed to move inward, which in turn causes the U-shaped clamp 18 to move towards the outer wall of the concentrator 9 through the connecting rod 14. This process is repeated to fix the storage bucket 6, thus achieving the effect of quickly assembling the measuring device. When performing the measurement operation, first... First, add sufficient water to the storage tank 6 until the water level reaches the designated line. Then, place the shellfish to be tested completely into the storage tank 6. At this time, the water inside the storage tank 6 will drain out through the water outlet 8 and flow along the guide channel 7 into the concentrator 9, and then flow into the measuring cup 10 through the concentrator 9. Then, the staff will measure and record the total volume data M1 using the weighing tray 5. Finally, the weighing tray 5 will be zeroed using the zeroing button in the control button 3. Then, the above process will be repeated to measure and record the shell cavity volume M2 and the soft body volume M3 of the shellfish. Finally, the mass of water equal to the volume of the shellfish will be measured using the weighing tray 5. The shell cavity volume M0 will be indirectly obtained through density conversion, i.e., M0 = M1 - M2. Then, based on the ratio of the shell cavity volume M0 to the soft body volume M3, i.e., C F = (M3 / M0)×100%, which can be used to calculate the body condition of shellfish, and then accurately obtain the shell cavity volume and body condition index of the shellfish to be tested, thus achieving the effect of rapid detection of shellfish body condition.
