Description

Technical Field

[0001] The utility model relates to the field of microalgae identification, in particular to a sampling device for microalgae identification. Background Art

[0002] Microalgae are a type of tiny single-cell or multi-cell algae organisms that usually grow in water bodies, including freshwater and seawater environments. For scientific research, solutions containing a large amount of microalgae are usually cultured inside containers. When identifying microalgae, a sampling device is used to penetrate into the microalgae solution to extract the solution. Common sampling devices are mostly used to sample solutions at a certain depth in the microalgae solution. In order to ensure the accuracy of the identification results, sampling of solutions at different depths requires multiple use of the sampling device for extraction, which is not convenient for sampling microalgae solutions at different depths. At the same time, the solvent of the sampling device is usually integrally formed, which makes internal cleaning too troublesome.

[0003] After searching, Chinese patent announcement number: CN217980907U discloses a sampling device for microalgae identification, including a sampling tube, a sleeve is arranged on one side of the top of the sampling tube, a piston block is slidably inserted and connected with the inner cavity of the sleeve, a connecting rod, the bottom end of which is fixedly connected with the top of the piston block, and a sampling mechanism is arranged on the sampling tube. The sampling mechanism includes multiple chambers, multiple water inlets are fixedly inserted at equal intervals on the front of the sampling tube, multiple fixed tubes are fixedly inserted at equal intervals on one side of the sampling tube, a connecting tube is fixed at one end of the multiple fixed tubes, and a valve is fixed on the inner wall of the water inlet. The utility model vertically inserts the sampling tube into the microalgae solution, and as the piston block moves vertically upward in the inner cavity of the sleeve, the connecting tube and the fixed tube absorb the air in the inner cavities of the multiple chambers, so that the solution squeezes and deforms the valve, and microalgae solutions of different depths flow from the water inlet into the bottom of the inner cavities of different chambers, thereby realizing the sampling of microalgae solutions of different depths.

[0004] In the above technology, although the structure designed by it can sample microalgae solutions at different depths at the same time, in fact, the air pressure generated by the movement of the piston block sucks the solution into multiple chambers. When discharging, due to the influence of air pressure, it may be necessary to push the piston block to drain the microalgae solution in the chamber. The movement of the piston block may control the flow of air in multiple chambers, and multiple chambers will also flow out together. It is necessary to prepare collection tanks and aim them at water outlets of different depths respectively. The operation is too troublesome and the practicality is too low. At the same time, it is not convenient to clean the inside of the chamber, which may affect the identification results of other microalgae. Therefore, a sampling device for microalgae identification is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a sampling device for microalgae identification, comprising a rectangular sealed shell 1, a sampling shell 2 is fixedly connected to the lower surface of the rectangular sealed shell 1, a groove 6 is arranged at the front end of the upper surface of the rectangular sealed shell 1, a suction component 4 is arranged on the upper surface of the rectangular sealed shell 1, a through groove 11 is opened on the inner wall of the sampling shell 2, a rectangular groove 9 is arranged on the lower surface of the sampling shell 2, the inner wall size of the rectangular groove 9 is adapted to the plug plate 72 to ensure the stability of the installation, the inner wall of the rectangular groove 9 is provided with a snap-in groove 10, the sampling shell 2 An isolation component 7 is provided on the lower surface, and the suction component 4 includes a round rod 43, which penetrates and is slidably connected to the upper surface of the rectangular sealed shell 1, and a rectangular plate 41 is fixedly connected to the upper surface of the round rod 43, and a piston block 44 is fixedly connected to the lower surface of the round rod 43. The piston block 44 is adapted to each chamber provided inside the rectangular sealed shell 1 to ensure that when the piston moves, the air inside the rectangular sealed shell 1 and the sampling shell 2 can be squeezed to ensure smooth sampling. The piston block 44 is connected to the inner wall of the rectangular sealed shell 1.

[0032] Reference Figure 3 The isolation assembly 7 includes an isolation plate 74, which slides on the inner wall of the through groove 11. There are multiple groups of isolation plates 74 to divide the interior of the sampling shell 2 into multiple groups of storage spaces. Multiple groups of one-way water inlet valves 3 correspond in sequence to ensure that microalgae solutions of different depths can be successfully collected. The lower surface of the isolation plate 74 is fixedly connected to the bottom plate 71, and the upper surface of the bottom plate 71 contacts the lower surface of the sampling shell 2.

[0033] Reference Figure 1 - Figure 3The front surface of the sampling shell 2 is provided with a one-way water inlet valve 3 in multiple groups, and the bottom end of the rear surface of the sampling shell 2 is provided with a one-way water outlet valve 5 in multiple groups. The one-way water inlet valve 3 and the one-way water outlet valve 5 are prior arts, both of which control the flow direction of the fluid in the pipeline to prevent reverse flow, but the one-way water inlet valve 3 can only ensure that the fluid enters the interior of the sampling shell 2, while the one-way water outlet valve 5 is the opposite. The switches of these two structures are both controlled by air pressure. The upper surface of the sampling shell 2 is provided with air holes 8 in multiple groups. The multiple groups of air holes 8 can make the multiple chambers inside the rectangular sealing shell 1 and the storage space separated by the inner wall of the sampling shell 2 through the isolation plate 74 connected in sequence, ensuring that the discharge of solutions of different depths can be controlled separately, thereby improving practicality.

[0034] Reference Figure 3 The suction component 4 also includes a slide rod 45, which is slidably connected to the inner wall of the groove 6. A spring 46 is sleeved on the outer wall of the slide rod 45. The spring 46 always pulls the connecting frame 42 downward by its own elasticity to ensure that it can be quickly reset to prevent it from hindering the discharge of materials. One end of the spring 46 is fixedly connected to the inner wall of the groove 6, and the other end of the spring 46 is fixedly connected to the upper surface of the slide rod 45.

[0035] Reference Figure 2 - Figure 3 A connecting frame 42 is fixedly connected to the upper surface of the sliding rod 45, and the connecting frame 42 can ensure that solutions of different depths are collected synchronously, thereby improving the sampling efficiency. The lower surface of the connecting frame 42 contacts the upper surface of the rectangular sealing shell 1, and the upper surface of the connecting frame 42 contacts the lower surface of the rectangular plate 41. The inner wall of the rectangular sealing shell 1 is provided with multiple chambers. The multiple chambers can realize separate control of solutions of different depths, thereby improving the practicality. There are multiple groups of piston blocks 44, and the pistons of the multiple groups of piston blocks 44 are connected to the inner walls of the multiple groups of chambers.

[0036] Reference Figure 3 - Figure 4 The right end of the upper surface of the bottom plate 71 is fixedly connected with an insert plate 72, and the insert plate 72 slides on the inner wall of the rectangular groove 9. A rubber block 73 is fixedly connected to the right surface of the insert plate 72. The rubber block 73 has a certain elasticity. When the insert plate 72 is inserted into the inner wall of the rectangular groove 9, it will deform. When the rubber block 73 overlaps with the card slot 10, it will rebound and get stuck on the inner wall of the card slot 10, which improves the speed of installation. The rubber block 73 contacts the inner wall of the card slot 10.

[0037] Working principle: When in use, the sampling shell 2 is completely inserted into the microalgae solution. At this time, the connecting frame 42 can be pulled, and the connecting frame 42 will drive the sliding rod 45 to slide on the inner wall of the groove 6 and squeeze the spring 46. At the same time, the connecting frame 42 will drive multiple groups of rectangular plates 41 to move. The rectangular plate 41 will drive the piston block 44 to perform piston movement on the inner wall of the rectangular sealing shell 1 through the round rod 43. The piston movement of the piston block 44 will suck out the air on the inner wall of the sampling shell 2 through the air hole 8. At this time, the external solution will enter the inner wall of the sampling shell 2 through the one-way water inlet valve 3 through the action of air pressure, because the inner wall of the sampling shell 2 is isolated by multiple groups of isolation plates 74. At the same time, the one-way water inlet valves 3 of different heights correspond to different separated spaces, so that microalgae solutions of different depths can be sampled, which is quick and convenient. After the sampling is completed, the connecting frame 42 can be loosened first, and the connecting frame 42 will be reset by the elastic reverse movement of the spring 46.

[0038] When discharging the material, it is only necessary to push the rectangular plate 41, and the rectangular plate 41 will drive the piston block 44 to move through the round rod 43. At this time, the piston block 44 will squeeze the air on the inner wall of the rectangular sealing shell 1 and squeeze out the microalgae solution inside the sampling shell 2 through the air hole 8. The microalgae solution will be discharged through the one-way water outlet valve 5. The appraiser can discharge the microalgae solutions of different depths separately without preparing multiple solvent tanks. At the same time, it is convenient to align the feed hole of the solvent tank, which improves practicality.

[0039] When it is necessary to clean the inner wall of the sampling shell 2, it is only necessary to pull the bottom plate 71 with force. The bottom plate 71 will simultaneously drive the plug plate 72 and the isolation plate 74 to move. At this time, the rubber block 73 will be squeezed and deformed, and disengage from the inner wall of the card slot 10. In this way, the isolation plate 74 can be taken out, and the bottom of the sampling shell 2 will also be open, which is convenient for cleaning the inside of the sampling shell 2 and the isolation plate 74, thereby improving convenience. During installation, it is only necessary to insert the isolation plate 74 into the inner wall of the through groove 11, and at the same time insert the plug plate 72 into the inner wall of the rectangular groove 9. The card slot 10 will be squeezed and deformed during the process of inserting the plug plate 72 into the inner wall of the rectangular groove 9 until the rubber block 73 overlaps with the card slot 10. At this time, the rubber block 73 will be elastically clamped on the inner wall of the card slot 10, so that the isolation component 7 can be successfully installed.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
