Description

Technical Field

[0001] This invention belongs to the field of food source research technology for Relict Gulls, and specifically relates to a microscopic examination device for Relict Gull feces. Background Technology

[0002] The Relict Gull (scientific name: *Larus relictus*) is an endangered migratory waterfowl belonging to the genus *Larus* in the family Laridae. It is a medium-sized waterfowl, measuring approximately 40 cm in length. Statistics indicate that the breeding population in the former Soviet Union exceeded 2,000 pairs, while a breeding population of over 1,200 pairs has been found in desert lakes in western Inner Mongolia, China. As of 2006, the global population was estimated at around 3,000 pairs. To protect this rare species, the International Union for Bird Conservation has listed it in the IUCN Red List of Threatened Species, and China has designated it as a Class I protected animal.

[0003] To better protect the Relict Gull, investigating food availability is a crucial aspect of Relict Gull research and provides a scientific basis for its conservation. Fecal microscopy, a common method for detecting Relict Gull food sources, is effective. However, fecal testing often involves manual operation of the equipment by the testing personnel, resulting in direct contact with the sample and posing a potential health risk. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a relict gull fecal microscopy device, which solves the problem that current fecal microscopy examinations of relict gulls are mostly manual operations involving direct contact with the sample, thus affecting the health of the examiners. The technical solution adopted by this invention is as follows:

[0005] A microscopic examination device for relict gull feces includes a sample collection tube and an isolation hood. The isolation hood houses a microscope and a stage. A slide placement stage is mounted on the isolation hood. One end of the stage extends out of the isolation hood and is located within the slide placement stage. The placement stage has a placement opening for inserting a sample slide. The stage is equipped with a first conveyor belt, a first telescopic limiter, and a second telescopic limiter. The distance between the placement opening and the first telescopic limiter is equal to the distance between the first and second telescopic limiters. A collection groove is installed below one end of the stage inside the isolation hood. A stepper motor and a placement tube are mounted on the isolation hood. An installation shaft is connected to the shaft of the stepper motor, and a sealing slide and a mounting bracket are mounted on the installation shaft. The mounting bracket has a through hole on the sealing plate, and a C-shaped buckle and a top ring corresponding to the through hole on the mounting bracket. The sample collection tube includes a tube body and a cap body. A first piston is provided in the cap body, and a top rod is provided on the first piston. A liquid outlet tube is provided in the tube body. A positioning groove and a piston groove are provided at the bottom end of the tube body. A connecting groove connected to the liquid outlet tube is provided in the piston groove. A spring and a second piston are provided in the piston groove. A first connecting rod is provided on the second piston, and a second connecting rod is connected to the first connecting rod. A sealing cap is provided on the second connecting rod. A U-shaped frame is installed on the isolation cover. A boss is provided on the U-shaped frame, and a pressure sensor is installed in the boss. A recovery tank is installed inside the isolation cover, and a skid plate is provided above the recovery tank.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, a water tank and a wastewater trough are installed inside the isolation enclosure. A cleaning seat is installed on one end of the stage, the wastewater trough is located below the cleaning seat, and the collection trough is located below the end of the cleaning seat. A ramp is provided at the connection between the cleaning seats. A second conveyor belt is installed on the cleaning seat, and several inclined limiting plates are installed on the second conveyor belt. A cleaning frame is installed on the cleaning seat, and a rinsing device is provided on the cleaning frame. The rinsing device has a built-in water pump, and the water inlet pipe of the water pump is located inside the water tank. After testing, the sample slide on the stage slides slides onto the second conveyor belt and moves at an angle under the action of the limiting plates. The rinsing device can rinse the sample slide to remove bird droppings. The cleaned sample slide falls into the collection trough for recycling.

[0008] Furthermore, the cleaning seat is equipped with a water-blocking baffle. The water-blocking baffle prevents sewage from flowing out along both sides of the cleaning seat during the rinsing process.

[0009] Furthermore, the collection tank is filled with clean water. The clean water cushions the sample slides as they fall into the collection tank, preventing damage from impact.

[0010] Furthermore, a filter frame is installed inside the collection tank. The filter frame can remove all sample slides that fall into the collection tank, making it convenient to use.

[0011] Furthermore, the placement port is an flared groove, with pre-drilled slots at both ends. This facilitates the placement of the sample slide into the placement port.

[0012] Furthermore, the isolation cover is provided with a limiting groove, and both the wastewater tank and the collection tank are located within the limiting groove. This facilitates positioning when the wastewater tank and the collection tank are placed inside the isolation cover.

[0013] Furthermore, both the wastewater tank and the collection tank are equipped with magnetic blocks, and the wastewater tank and the collection tank are magnetically fixed together. The wastewater tank and the collection tank can be pulled out from the isolation cover at the same time, and the wastewater tank and the collection tank are easy to disassemble.

[0014] Furthermore, the top of the outlet tube is higher than the bottom of the inner cavity of the tube. The sample is collected from the middle of the sample solution during discharge.

[0015] The beneficial effects of this invention are:

[0016] During sampling, Relict Gull feces are placed in a sampling tube and mixed with water to form a sample solution. For testing, the sampling tube is placed into the placement tube, and the sample slide is placed into the placement opening. The stepper motor and the first conveyor belt are started. The first conveyor belt moves the sample slide to the position of the first telescopic limiter. The stepper motor drives the sealing slide to rotate. When the through hole aligns with the placement tube, the sampling tube falls into the C-shaped buckle and is supported by the top ring. The sampling tube rotates with the sealing slide and contacts the boss. The boss squeezes the top rod to squeeze the sample solution onto the sample slide. Then, the first telescopic limiter retracts, and the sample slide moves with the first conveyor belt to the second telescopic limiter for microscope testing. During the testing process, the Relict Gull feces do not come into contact with the operator and will not affect the testing personnel. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1-9As shown, a microscopic examination device for Relict Gull feces includes a sample collection tube 6 and an isolation hood 1. A microscope 2 and a stage 3 are housed inside the isolation hood 1. A slide placement stage 11 is provided on the isolation hood 1. One end of the stage 3 extends out of the isolation hood 1 and is located within the slide placement stage 11. The placement stage 11 has a placement opening 12 for inserting a sample slide 7. The stage 3... The enclosure 1 is equipped with a first conveyor belt 31, a first telescopic limiter, and a second telescopic limiter. The distance between the placement port 12 and the first telescopic limiter is equal to the distance between the first telescopic limiter and the second telescopic limiter. A collection trough 42 is installed below one end of the platform 3 inside the isolation cover 1. The collection trough 42 is used to collect used sample slides 7. A stepper motor 15 and a placement tube 14 are installed on the isolation cover 1. The placement tube 14 communicates with the interior of the isolation cover 1. A mounting shaft 16 is connected to the rotating shaft of the stepper motor 15. A sealing plate 161 and a mounting bracket 163 are installed on the mounting shaft 16. When the stepper motor 15 runs, the sealing plate 161 and the mounting bracket 163 rotate. The sealing plate 161 has a through hole 162, and the mounting bracket 163 has a through hole 162. Correspondingly, the C-shaped buckle 164 and the top ring 165, when the through hole 162 of the sealing plate 161 corresponds to the placement tube 14, the sampling tube 6 placed in the placement tube 14 falls into the C-shaped buckle 164 and is supported by the top ring 165. The sample sampling tube 6 includes a tube body 61 and a cover body 62. The cover body 62 is provided with a first piston 63, and the first piston 63 is provided with a top rod 631. The tube body 61 is provided with a liquid outlet tube 65. The bottom end of the tube body 61 is provided with a positioning groove 661 and a piston groove 662. The piston groove 662 is provided with a connecting groove 663 that communicates with the liquid outlet tube 65. The piston groove 662 is provided with a spring 671 and a second piston 67. The second piston 67 is provided with a first connecting rod 642, and the first connecting rod 642 is connected to the second connecting rod 641. The tube 61 is equipped with a cap 64. When the top rod 631 is squeezed, the pressure inside the tube 61 increases and the first piston 63 cannot move. At this time, the second piston 67 moves and the spring 671 is compressed. After the pressure inside the tube 61 is released, the first piston 63 can move to squeeze out the sample solution. The sample solution slides down from the first connecting rod 641 and drips onto the sample slide 7. A U-shaped frame 10 is installed on the isolation cover 1. A boss 101 is provided on the U-shaped frame 10. A pressure sensor is installed in the boss 101. A recovery tank 18 is installed inside the isolation cover 1. A pry plate 17 is provided above the recovery tank 18. After the sampling tube 6, which rotates with the C-shaped buckle 164, comes into contact with the pry plate 17, the sampling tube 6 can be pried out of the C-shaped buckle 164 and fall into the recovery tank 18.

[0031] Specifically, a water tank 43 and a wastewater trough 41 are installed inside the isolation cover 1. A cleaning seat is installed on one end of the platform 3. The wastewater trough 41 is located below the cleaning seat. The collection trough 42 is located below the end of the cleaning seat. A ramp is provided at the connection between the cleaning seats. A second conveyor belt 32 is installed on the cleaning seat. Several inclined limiting plates 321 are installed on the second conveyor belt 32. A cleaning frame 51 is installed on the cleaning seat. A rinsing device 52 is provided on the cleaning frame 51. The rinsing device 52 has a built-in water pump. The water inlet pipe of the water pump is located inside the water tank 43. After the sample slide 7 on the platform 3 is tested, it slides onto the second conveyor belt 32 and moves at an angle under the action of the limiting plates 321. The rinsing device 52 can rinse the sample slide 7 to remove bird droppings. The cleaned sample slide 7 falls into the collection trough 42 for recycling.

[0032] Specifically, the cleaning seat is equipped with a water-blocking baffle 33, which can prevent sewage from flowing out along both sides of the cleaning seat during the rinsing process.

[0033] Specifically, the collection tank 42 is filled with clean water. When the cleaned sample slide 7 falls into the collection tank 42, the clean water cushions it and prevents the sample slide 7 from being damaged by impact.

[0034] Specifically, a filter frame 44 is installed inside the collection tank 42, through which all sample slides 7 that fall into the collection tank 42 can be carried out, making it convenient to use.

[0035] Specifically, the placement port 12 is an flared groove, and the two ends of the placement port 12 are provided with reserved grooves 13 to facilitate the placement of the sample slide 7 into the placement port 12.

[0036] Specifically, the isolation cover 1 is provided with a limiting groove 19, and the wastewater tank 41 and the collection tank 42 are both located in the limiting groove 19, which facilitates positioning when the wastewater tank 41 and the collection tank 42 are placed into the isolation cover 1.

[0037] Specifically, both the wastewater tank 41 and the collection tank 42 are equipped with magnetic blocks, and the wastewater tank 41 and the collection tank 42 are magnetically fixed together. The wastewater tank 41 and the collection tank 42 can be pulled out from the isolation cover 1 for cleaning at the same time, and the wastewater tank 41 and the collection tank 42 are easy to disassemble.

[0038] Specifically, the top of the outlet tube 65 is higher than the bottom of the inner cavity of the tube body 61, and the sample solution is obtained from the middle when the sample is discharged.

[0039] During the sampling process, the sampling tube 6 is filled with Relict Gull droppings. Water is pre-filled in the sampling tube 6, and the droppings mix with the water to form a sample solution. When microscopic examination is required, the sampling tube 6 is placed into the placement tube 14, and the sample slide 7 is placed into the placement opening 12. Then, the stepper motor 15 and the first conveyor belt 31 are started. The first conveyor belt 31 moves the sample slide 7 to the position of the first telescopic limiter. The stepper motor 15 drives the sealing slide 161 to rotate. When the through hole 162 aligns with the placement tube 14, the sampling tube 6 falls into the C-shaped buckle 164 and is supported by the top ring 165. The sampling tube 6 rotates with the sealing slide 161 and contacts the boss 101. The boss 101 squeezes the top rod 631, squeezing out the sample solution which drips onto the sample slide 7. Then, the first telescopic limiter is closed, and the first telescopic limiter retracts, no longer obstructing the sample slide 7. The sample slide 7 moves with the first conveyor belt 31 to the second telescopic limiter for examination by the microscope 2. Sampling tube 6 continues to move and, under the action of skid plate 17, detaches from C-shaped buckle 164 and is discharged into recovery tank 18, allowing for the insertion of more sampling tubes. Sample slide 7 moves below microscope 2. After testing, the second telescopic limiter closes, and sample slide 7 continues to move, sliding onto the second conveyor belt 32. Under the action of limit plate 321, sample slide 7 tilts and moves, and is rinsed by rinsing device 52 to remove fecal samples. After rinsing, sample slide 7 continues to move and finally falls into collection tank 42, completing the testing.

[0040] The above provides a detailed description of a relict gull fecal microscopic examination device provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
