Description

Technical Field

[0001] This utility model relates to the technical field of benthic animal collection devices, and in particular to a multifunctional sampling tool for benthic animals. Background Technology

[0002] Benthic animals are animal communities that live at the bottom of water bodies. They inhabit the surface or interior of the substrate and are an important part of aquatic ecosystems. Benthic animals are diverse, including invertebrates, small fish, and other organisms. They play an important role in the food chain and are also very sensitive to environmental changes. Changes in their community structure reflect the ecological status of the water body. They are often used as indicator species for aquatic ecological monitoring and evaluation. Therefore, they are often sampled and collected. After the collected benthic animal samples are cleaned, they are poured into a white porcelain dish with some water added and then selected using sampling tools such as tweezers.

[0003] However, existing tweezers pose a risk of static electricity at the tips during actual use. This causes them to scare away nearby benthic animals before even touching the water surface of the white porcelain dish, especially when there are fast-moving benthic animals present. This affects the efficiency of the selection process. In addition, additional lighting is required in low-light conditions, and older researchers or those with poor eyesight often miss or fail to see the samples. Therefore, a multifunctional benthic animal selection tool is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multifunctional sampling tool for benthic animals, which aims to improve the existing technology that uses tweezers to select benthic animal samples. This tool is designed to address the risk of static electricity at the tweezers tip, which affects the selection efficiency, and the need to turn on a separate light.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional sampling tool for benthic animals, comprising a tweezer handle, an anti-static tweezer tip fixedly connected to the left end of the tweezer handle, a hinge seat fixedly connected to the front surface of the tweezer handle, a rotating frame hinged to the left side of the hinge seat, a limiting unit provided on the front side of the rotating frame for limiting the rotation frame, a magnifying glass fixedly connected inside the rotating frame, and annular LED light strips fixedly connected to the upper and lower sides of the inner wall of the rotating frame, a power supply compartment fixedly connected to the bottom surface of the hinge seat, and a control button fixedly connected to the right surface of the hinge seat.

[0006] As a further description of the above technical solution:

[0007] The control buttons and power supply compartment are electrically connected to the ring-shaped LED light strip.

[0008] As a further description of the above technical solution:

[0009] The limiting unit includes a connecting column, which is fixedly connected to the front right side surface of the rotating frame. A fixing cylinder is fixedly connected to the front of the hinge seat, and an annular rubber pad is fixedly connected inside the fixing cylinder.

[0010] As a further description of the above technical solution:

[0011] The front end of the connecting post passes through the rotating frame, and the front end of the connecting post is inserted into the interior of the annular rubber pad.

[0012] As a further description of the above technical solution:

[0013] The connecting column and the annular rubber pad are interference-fitted.

[0014] As a further description of the above technical solution:

[0015] A rubber airbag is fixedly connected to the back of the tweezer handle. A suction tube is fixedly connected to the left side surface of the rubber airbag. A porous filter element is fixedly connected inside the suction tube. A fixing plate is fixedly connected to the rear inner wall surface of the rubber airbag. A spring is fixedly connected to the front surface of the fixing plate.

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0022] 2. In this utility model, the combination of the rubber airbag, the suction tube, and the porous filter element allows for the selection of benthic animal samples that are inconvenient to grasp with tweezers.

[0029] 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.

[0030] Reference Figures 1-2 This utility model provides an embodiment of a multifunctional sampling tool for benthic animals, including a tweezer handle 1. An antistatic tweezer tip 2 is fixedly connected to the left end of the tweezer handle 1. The surface of the antistatic tweezer tip 2 is coated with an antistatic coating to effectively prevent the carrying of static electricity. A hinge seat 3 is fixedly connected to the front surface of the tweezer handle 1. A rotating frame 4 is hinged to the upper part of the hinge seat 3. The rotating frame 4 can rotate 45 degrees left and right around the hinge seat 3. A limiting unit 40 is provided on the front side of the rotating frame 4. The limiting unit 40 includes a connecting post 41. The connecting post 41 is fixedly connected to the front surface of the right end of the rotating frame 4. When the rotating frame 4 rotates, it can drive the connecting post 41 to rotate synchronously. A fixing cylinder 42 is fixedly connected to the front of the hinge seat 3. An annular rubber pad 43 is fixedly connected inside the fixing cylinder 42. The front end of the connecting post 41 passes through the rotating frame 4 and is inserted into the interior of the annular rubber pad 43.

[0031] When the rotating frame 4 rotates to adjust the angle, it will drive the connecting column 41 to rotate synchronously inside the annular rubber pad 43. The connecting column 41 and the annular rubber pad 43 are interference-fitted. The connecting column 41 will squeeze the inner wall of the annular rubber pad 43, causing the inner wall of the annular rubber pad 43 to be compressed and deformed, thereby generating a large frictional force between it and the connecting column 41. After the rotating frame 4 rotates to the required angle and stops, the frictional force generated by the interference fit between the annular rubber pad 43 and the connecting column 41 can automatically limit the rotating frame 4, so that the rotating frame 4 can maintain stable use.

[0032] Reference Figures 1-2 A magnifying glass 5 is fixedly connected inside the rotating frame 4. The magnifying glass 5 can magnify the selection image in the white porcelain plate, making it convenient for staff to select samples. At the same time, through the cooperation of the rotating frame 4, the hinge seat 3 and the limiting unit 40, the magnifying glass 5 can be bent and adjusted at multiple angles, making it convenient to adjust the observation angle. The operation is simple. The upper and lower sides of the inner wall of the rotating frame 4 are fixedly connected to the ring LED light strip 6. The bottom surface of the hinge seat 3 is fixedly connected to the power supply compartment 7. The right side surface of the hinge seat 3 is fixedly connected to the control button 8. The control button 8 and the power supply compartment 7 are electrically connected to the ring LED light strip 6. The power supply compartment 7 has a built-in button battery, which can power the ring LED light strip 6 so that the ring LED light strip 6 can emit light, improving the selection environment conditions. The control button 8 can adjust the brightness and start / stop of the ring LED light strip 6 to adjust the brightness of the light according to different ambient light intensities.

[0033] Reference Figures 3-4 A rubber air bladder 9 is fixedly connected to the back of the tweezer handle 1, and a suction tube 10 is fixedly connected to the left side surface of the rubber air bladder 9. When the rubber air bladder 9 is squeezed, the internal air can be discharged to the outside through the suction tube 10. At this time, a negative pressure is generated inside the rubber air bladder 9. After the rubber air bladder 9 is released, the rubber air bladder 9 returns to its shape and forms a suction force at the left end of the suction tube 10 to adsorb benthic animal samples. The front surface of the suction tube 10 is fixedly connected to the back of the antistatic tweezer tip 2 located on the rear side, which can ensure the stability of the suction tube 10 in use.

[0034] A porous filter element 11 is fixedly connected inside the suction tube 10. The porous filter element 11 can filter the water flowing into the suction tube 10, preventing impurities in the white porcelain plate from entering the rubber airbag 9 and making it difficult to discharge, thus affecting the use of the rubber airbag 9. At the same time, it can prevent some small samples from being sucked into the rubber airbag 9. A fixing plate 12 is fixedly connected to the inner rear wall surface of the rubber airbag 9, and a spring 13 is fixedly connected to the front surface of the fixing plate 12. The front end of the spring 13 is fixedly connected to the back of the tweezer handle 1. When the rubber airbag 9 is squeezed, the fixing plate 12 is pressed simultaneously, causing the fixing plate 12 to move towards the tweezer handle 1 and squeeze the spring 13. The spring 13 is compressed and generates elastic potential energy. After the rubber airbag 9 is released, the compression on the fixing plate 12 is released, allowing the fixing plate 12 to quickly return to its original position under the action of the elastic potential energy of the spring 13. This helps the rubber airbag 9 to recover its deformation and prevents the rubber airbag 9 from failing to recover and affecting its use.

[0035] Working principle: The anti-static tweezers tip 2 avoids the influence of static electricity on the selection of benthic animals. The user can rotate the rotating frame 4 to rotate the magnifying glass 5 to the desired angle to magnify the sample in the white porcelain dish, making it convenient for the user to observe and select. At the same time, the user can activate the ring LED light strip 6 for illumination through the control button 8 and adjust the brightness of the light according to different ambient light intensities to assist the user in operation. When dealing with some small samples that are inconvenient to handle with tweezers, the user can first press the rubber air bladder 9 to expel the internal air through the suction tube 10. By squeezing the fixing plate 12 and the spring 13, the spring 13 is compressed to generate elastic potential energy. Then, the end of the suction tube 10 is brought close to the sample to be sampled. Finally, the rubber air bladder 9 is released, allowing the rubber air bladder 9 to recover its deformation under the action of the elastic potential energy of the spring 13. Then, the suction force is generated at the end of the suction tube 10 to adsorb and fix the sample. The operation is simple and the structure is simple.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
