Description

Technical Field

[0001] The utility model relates to the technical field of feces sampling, in particular to a sterile sampler for giant panda feces. Background Art

[0002] The significance of giant panda feces sampling is mainly reflected in the following aspects:

[0003] Monitoring the population and distribution of giant pandas: By collecting and analyzing panda feces, researchers can identify individual pandas and accurately calculate the population. For example, DNA analysis of feces can determine the number and distribution of giant pandas within protected areas.

[0004] Assessing the health of giant pandas: Giant panda feces contain a wealth of information related to their health. Researchers can analyze fecal composition and digestion patterns to assess a panda's digestive capacity and health. For example, measuring the length and shape of bamboo nodes in feces can reveal a panda's age and health.

[0005] Studying the eating habits and living habits of giant pandas: Giant pandas primarily feed on bamboo. By analyzing the bamboo components in their feces, we can understand their eating habits and food sources. In addition, the mucus components in the feces can also be used for DNA analysis to further study the genetic diversity of giant pandas.

[0006] Existing fecal sampling technology has the following shortcomings:

[0007] 1. Panda feces are usually sampled directly without considering the impact of microorganisms in the surface adhering to the feces, such as soil, weeds and other pollutants adhering to the surface of the feces, which makes it impossible to achieve sterile sampling.

[0008] 2. Collection containers generally do not have refrigeration function. When the temperature is high, the sampled feces cannot be preserved at low temperatures after storage. The feces samples are prone to breeding bacteria or deterioration, thus affecting subsequent research work. Utility Model Content

[0021] Preferably, a switch button is installed on the outer wall of the gripping plate.

[0022] The beneficial effects of the utility model are:

[0023] 1. The present invention is designed with a prying mechanism. When sampling, the two prying plates are first vertically inserted into the surface of the feces. Then, the manual component drives the two traction components to operate, thereby driving the two half-shells away from each other through the two traction components, and at the same time driving the two prying plates away from each other, thereby prying away the surface of the feces. In this way, pollutants such as soil and weeds adhering to the surface of the feces can be pried away, preventing microorganisms in the adhered objects from contaminating the feces sample and affecting subsequent research work, thereby achieving the effect of sterile sampling.

[0024] 2. The present invention utilizes a cooling mechanism, namely an interlayer and a refrigeration assembly, to activate four refrigeration plates via a controller when deep feces are drawn into the storage tube, thereby cooling the feces temporarily stored in the storage tube and achieving a low-temperature preservation effect. This can inhibit excessive bacterial growth and delay sample deterioration, facilitating subsequent research. Considering that a refrigeration plate generally has a cold end on one side and a hot end on the other, when installing the refrigeration plate, the cold end is directed toward one end of the feces and the hot end toward the heat sink, thereby facilitating the transfer of heat from the heat sink to the outside of the storage tube, preventing heat from accumulating in the interlayer and reducing the low-temperature preservation effect on the feces sample.

[0025] 3. The present invention utilizes two traction components to achieve coordinated operation of the prying and sampling mechanisms. This means that while the two prying plates move away from each other to pry away surface contaminants, they simultaneously drive the suction tube vertically into the deeper layers of the stool, where the sample is then drawn through the extraction component. This reduces the number of drive sources used in the sampler, lowers power consumption, reduces manufacturing costs, and enhances portability.

[0026] 4. The utility model is designed with two half-shells. After each sampling is completed and the sampler is cleaned and disinfected, the two tightly closed half-shells seal and protect the suction tube, so that the suction tube will not be exposed to the outside air when the sampler is not in use, preventing contamination, which is beneficial to the next sampling work and plays an auxiliary role in sterile sampling.

[0040] Reference Figures 1 to 8 As shown, a sterile sampler for giant panda feces includes a gripping plate 1;

[0041] It also includes a prying mechanism, a sampling mechanism and a cooling mechanism;

[0042] The sampling mechanism is provided on the outer wall of the gripping plate 1 and includes a suction tube 2, a storage cylinder 3, and an extraction assembly. The storage cylinder 3 is slidably provided on the outer wall of the gripping plate 1 via two sliders 4. A suction port 5 is provided at the bottom of the storage cylinder 3. The suction tube 2 is detachably provided at the bottom of the suction port 5. The extraction assembly is inserted into the storage cylinder 3.

[0043] The prying mechanism is arranged on the outer wall of the gripping plate 1, and the prying mechanism includes a manual component, two prying plates 6, two half-shells 7 and two traction components. The manual component is arranged on the outer wall of the storage tube 3, and each half-shell 7 is slidably arranged on the bottom end of the gripping plate 1 through a slide rod 8. Each prying plate 6 is fixed to the bottom of a half-shell 7 through an L-shaped plate 9, and the two prying plates 6 are fitted together. Each traction component is arranged between one end of the storage tube 3 and a half-shell 7. After each cleaning and disinfection of the sampler, the two half-shells 7 can seal and protect the suction tube 2 when they are tightened, so that the suction tube 2 will not be exposed to the outside air when the sampler is not in use, thereby preventing contamination;

[0044] The cooling mechanism is provided on the storage tube 3 , and includes an interlayer 10 and a refrigeration assembly. The interlayer 10 is integrally formed and provided inside the storage tube 3 , and the refrigeration assembly is provided inside the interlayer 10 .

[0045] Reference Figures 1 to 8 As shown, the extraction component includes a linear motor 11, a push block 12 and an extrusion rod 13. The linear motor 11 is fixedly arranged at the top of the storage tube 3, the push block 12 is fixedly arranged on its output end, and the extrusion rod 13 is slidably arranged in the center of the storage tube 3. The bottom of the push block 12 is fixedly connected to the top of the extrusion rod 13. When the suction tube 2 moves vertically downward and inserts into the deep layer of feces, the sampler activates the switch button 30. After the controller receives the signal of the switch button 30, it activates the linear motor 11 through the controller, thereby driving the push block 12 to extend upward through its output end. Since its output end is fixedly connected to the extrusion rod 13 through the push block 12, the extrusion rod 13 slides vertically upward inside the storage tube 3, and the part located in the deep layer of feces is drawn from the suction port 5 to the interior of the storage tube 3 for temporary storage through the suction tube 2, thereby achieving the effect of sterile sampling. Here, it should be noted that the linear motor 11 is a motor type with a small size and light weight, which is conducive to reducing the overall weight of the sampler and improving the portability of the sampler.

[0046] Reference Figures 1 to 8 As shown, the manual assembly includes a knob 14, a worm gear 15, a worm 16, a screw 17 and a lifting block 18. The screw 17 is rotated on the outer wall of the gripping plate 1 through two support blocks. The worm gear 15 is fixed on the top of the screw 17. The lifting block 18 is fixed on the outer wall of the storage cylinder 3 through a U-shaped plate 19. The lifting block 18 is threadedly connected to the screw 17. The worm 16 is rotated on the outer wall of the gripping plate 1 through a rotating shaft. The worm 16 is meshed with the worm gear 15. The knob 14 is fixed at one end of the rotating shaft. When the giant panda is operated During the aseptic sampling of feces, the sampler first holds the gripping plate 1 and inserts the two dial plates 6 vertically into the giant panda feces. Then the sampler rotates the knob 14, thereby driving the worm 16 to rotate through the knob 14. Since the worm gear 15 is fixedly connected to the screw rod 17, the screw rod 17 is threadedly connected to the lifting block 18, and the end of the lifting block 18 away from the screw rod 17 is fixedly connected to the storage cylinder 3 through the U-shaped plate 19. The storage cylinder 3 is slidably connected to the guide rail provided on the gripping plate 1 through two sliders 4, thereby driving the storage cylinder 3 to descend vertically.

[0047] Reference Figures 1 to 8As shown, each traction assembly includes an L-shaped rod 20, a first plug rod 21 and a second plug rod 22. The L-shaped rod 20 is rotatably arranged at one end of the bottom of the gripping plate 1, the first plug rod 21 is fixedly arranged on the bottom outer wall of the storage cylinder 3, and the second plug rod 22 is fixedly arranged on the outer wall of one of the half-shells 7 through the mounting plate 23. The two ends of the L-shaped rod 20 are respectively provided with a first avoidance groove and a second avoidance groove for the first plug rod 21 and the second plug rod 22 to be plugged in. The top of each half-shell 7 is provided with a semicircular groove 24 for the suction tube 2 to pass through. When the storage cylinder 3 is vertically lowered, since the first plug rod 21 is fixedly connected to the bottom outer wall of the storage cylinder 3, the second plug rod 22 is fixedly connected to one of the half-shells 7 through the mounting plate 23. The L-shaped rod 20 is rotatably connected to the gripping plate 1, so that the first insertion rod 21 descends inside the first avoidance groove to drive the L-shaped rod 20 to rotate, and then drives the second insertion rod 22 to slide horizontally through the second avoidance groove. Since each half shell 7 is slidably connected to the gripping plate 1 through the sliding rod 8, the two half shells 7 are driven away from each other, thereby realizing the downward movement of the suction tube 2, that is, while the two half shells 7 move away from each other to push away the surface layer of feces, the suction tube 2 is moved vertically downward and inserted into the deep layer of feces. Here, it should be noted that by pushing away the surface layer of feces through the two prying plates 6, pollutants such as soil and weeds adhered to the surface of the feces can be pushed away, thereby preventing microorganisms in the adhered materials from contaminating the feces sample and affecting subsequent research work.

[0048] Reference Figures 1 to 8 As shown, the refrigeration assembly includes four refrigeration fins 25, and the four refrigeration fins 25 are arranged at equal intervals inside the interlayer 10. A number of heat dissipation grooves 26 are arranged at equal intervals on the outer wall of the storage tube 3 in the circumferential direction. The several heat dissipation grooves 26 are all connected with the interlayer 10. When deep feces are sucked into the interior of the storage tube 3, the four refrigeration fins 25 are started by the controller to refrigerate the feces temporarily stored in the storage tube 3, thereby achieving a low-temperature preservation effect, thereby inhibiting excessive bacterial growth and delaying sample deterioration, which is beneficial to subsequent research work. Considering that the refrigeration fin 25 generally has a cold end on one side and a hot end on the other side, when installing the refrigeration fin 25, its cold end is facing one end of the feces, and the hot end is facing the heat dissipation groove 26, so as to facilitate the heat dissipation from the heat dissipation groove 26 to the outside of the storage tube 3, preventing heat from accumulating in the interlayer 10 and reducing the low-temperature preservation effect of the feces sample.

[0049] Reference Figures 1 to 8 As shown, a limit block 27 is fixedly provided at one end of the bottom of the storage cylinder 3 near the suction port 5, and the top of the suction tube 2 is threadedly connected to the limit block 27. The suction tube 2 is designed to be threadedly connected to the limit block 27, so that the suction tube 2 can be disassembled and separated from the storage cylinder 3, thereby facilitating the removal and cleaning of the suction tube 2. At the same time, it is also convenient for quick replacement when the suction tube 2 is damaged.

[0050] Reference Figures 1 to 8As shown, the top of each paddle plate 6 is integrally formed with an inclined plate 28, and each L-shaped plate 9 is fixedly connected to a half-shell 7 by two bolts 29. When the two paddle plates 6 move away from each other to pry away the surface of feces, the inclined plate 28 has a buffering effect, reducing the resistance generated when the paddle plate 6 pries the feces, which is beneficial to increasing the speed of prying away the surface of feces, thereby facilitating the speed of inserting the suction tube 2 into the deep layer of feces, and improving the sampling efficiency. By fixing each L-shaped plate 9 to a half-shell 7 with two bolts 29, when the paddle plate 6 is damaged, it only needs to remove the L-shaped plate 9 to achieve quick replacement, so there is no need to replace the entire prying mechanism, which is beneficial to reducing maintenance costs.

[0051] Reference Figures 1 to 8 As shown, a switch button 30 is installed on the outer wall of the gripping plate 1, and a controller is installed on the outer wall of the sampler. The switch button 30 is electrically connected to the controller, and the linear motor 11 is electrically connected to the controller. The starting switch button 30 is mainly used to control the opening and closing of the linear motor 11, thereby realizing the sampling work.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
