Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to a water quality sample sealing device and tracking method for environmental monitoring. Background Technology

[0002] Currently, in the process of environmental monitoring sampling, after the samples are collected on site, they are packaged and preserved, and then sent to the laboratory for analysis. In order to ensure that the samples are original and to avoid damage or replacement during transportation, the samples need to be sealed during the process of sampling and laboratory analysis.

[0003] Existing water sample sealing devices generally require manual sampling and sealing, which is inefficient and makes it difficult to complete sampling and sealing operations in batches. It is also difficult to stir the water before sampling, resulting in uneven distribution of components in the water, which affects the accuracy of subsequent tests. After the sampling operation is completed in the water storage tank, the water in the storage tank needs to be drained, and then the next tank of water needs to be introduced for the next sampling. However, water residue from the previous tank can interfere with the water in the next tank, leading to inaccurate tests. To address these issues, the existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a water quality sample sealing device for environmental monitoring, in order to solve the problems mentioned in the background art. Existing water quality sample sealing devices generally require manual sampling and sealing, which is inefficient and difficult to complete in batches. Before sampling, it is difficult to stir the water, resulting in uneven distribution of components in the water, which affects the accuracy of subsequent detection. After the sampling operation is completed in the water storage tank, the water in the water storage tank needs to be drained, and then the next tank of water needs to be introduced into the water storage tank for the next sampling. However, the water residue in the previous tank will interfere with the water in the next tank, which will lead to inaccurate detection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water quality sample sealing device for environmental monitoring, comprising a support platform, a first rotating plate and a second rotating plate rotatably connected to the top of the support platform, a support bracket fixed to the outer side of the first rotating plate, water storage cylinders symmetrically fixed to both sides of the second rotating plate, a stirring rod rotatably connected to the inner side of the water storage cylinder, the stirring rod penetrating one side of the water storage cylinder and connected to a connecting mechanism, a rotating shaft penetrating the second rotating plate, and second locking blocks symmetrically fixed to both ends of the rotating shaft, the second locking blocks engaging with the connecting mechanism.

[0006] A first bracket is fixed to one side of the upper surface of the support platform, a drainage pipe is fixed to the first bracket, a water injection pipe is fixed to the top of the first bracket, a rotary valve is rotatably connected to the inner side of the water injection pipe, and a linkage rotation mechanism is fixed to the top of the second rotating plate.

[0007] A second bracket is fixed to the other side of the upper surface of the support platform, a second electric telescopic column is fixed to the top of the second bracket, and a packaging machine is fixed to the bottom of the second electric telescopic column.

[0008] Preferably, a first motor is fixed to the bottom of the support platform, and the top of the first motor is connected to the main sprocket. A second rotating plate is fixed to the top of the main sprocket. The first rotating plate passes through the top of the support platform and is connected to the driven sprocket. A chain is wound around the outside of the main sprocket and the driven sprocket, and the diameter of the main sprocket is larger than the diameter of the driven sprocket.

[0009] By adopting the above technical solution, the rotation of the main sprocket can drive the rotation of the second rotating plate, and the rotation of the secondary sprocket can drive the rotation of the first rotating plate.

[0010] Preferably, there are three hosting devices, and the three hosting devices are evenly distributed circumferentially on the first rotating plate.

[0011] By adopting the above technical solution, the first rotating plate can be rotated, making it convenient to use the three support plates in turn.

[0012] Preferably, the connecting mechanism includes a first locking block, which is fixed to the inner end of the stirring rod. The inner side of the first locking block is connected to the abutment block by a compression spring, and the outer side of the first locking block is engaged with a sleeve. The first locking block is composed of a square block and a round rod.

[0013] By adopting the above technical solution, after the second card block leaves the card sleeve, the card sleeve will automatically pop open, and the block on the first card block will leave the sleeve.

[0014] Preferably, support rings are symmetrically fixed on both sides of the top of the second rotating plate, the sleeve passes through the support rings and is connected to the ferrule, and a protruding ring is fixed on the outer side of the sleeve.

[0015] By adopting the above technical solution, when the sleeve springs open, the support ring will block the convex ring, preventing the sleeve from completely separating from the first locking block.

[0016] Preferably, a first magnet is fixed to both the top and bottom of the sleeve, and a second magnet is symmetrically fixed to both sides of the top of the second rotating plate.

[0017] By adopting the above technical solution, after the card sleeve pops open, the first and second magnets can be used to help the card sleeve rotate to a vertical position.

[0018] Preferably, a second motor is fixed to one side of the second rotating plate, and the output end of the second motor is connected to the first gear. The top of the first gear is meshed with the second gear, and a rotating shaft is fixed to the inner side of the second gear.

[0019] By adopting the above technical solution, the rotation of the second gear can drive the shaft to rotate.

[0020] Preferably, the linkage rotation mechanism includes a support column, which is fixed to the top of the second rotating plate. A disk is fixed to the top of the support column, and racks are symmetrically fixed to both sides of the disk.

[0021] By adopting the above technical solution, after the disk rotates and the rack meshes with the third gear, the third gear will rotate along with the rotation of the disk.

[0022] Preferably, a support bar is fixed to the front side of the water injection pipe, and a third gear is rotatably connected to the bottom of the support bar. The third gear is meshed with a rack, passes through the support bar, and is connected to a chain drive device. The output end of the chain drive device is connected to a worm gear, and a worm wheel is meshed with one side of the worm gear. The worm wheel passes through the front side of the water injection pipe and is connected to a rotary valve.

[0023] By adopting the above technical solution, the chain drive device can drive the worm to rotate, thereby driving the worm wheel and rotary valve to rotate.

[0024] A tracking method for a water quality sample sealing device for environmental monitoring includes the following steps:

[0025] S1. Insert the test tube into the holder in front of the first rotating plate. While the first rotating plate rotates 120 degrees clockwise, the second rotating plate rotates 180 degrees. After the water to be sampled is passed into the water storage cylinder on the right, the stirring rod rotates to automatically stir the water. After the water is passed into the test tube, the first rotating plate continues to rotate 120 degrees clockwise. At this time, the water storage cylinder containing the remaining water reaches the bottom of the water injection pipe. After draining the water in the water storage cylinder, clean water can be passed into the water storage cylinder for cleaning.

[0026] S2. After the second card block leaves the card sleeve, the card sleeve automatically pops open. When used with the first and second magnets, the card sleeve can automatically rotate to a vertical position.

[0027] S3. While cleaning the water storage tank, a second electric telescopic column and a sealing machine can be used to complete the sealing process of the test tubes.

[0028] S4. The rotation of the second rotating plate can drive the support column and the disc to rotate. After the rack and the third gear mesh together, the third gear rotates, thereby driving the chain drive device, worm, worm wheel and rotary valve to rotate. After the water storage tank leaves the bottom of the water injection pipe, the rotary valve automatically closes. After the water storage tank rotates to the bottom of the water injection pipe, the rotary valve automatically opens.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. This environmental monitoring water sample sealing device can achieve automatic stirring. After the water to be sampled is passed into the water storage tank on the right, the rotating shaft rotates, thereby driving the second clamping block, clamping sleeve, sleeve, first clamping block and stirring rod to rotate, which facilitates automatic stirring of the water to be sampled, so that the components in the water can be evenly distributed and the sampling effect is more accurate. After the second clamping block leaves the clamping sleeve, the clamping sleeve will automatically pop open, and the first magnet and the second magnet attract each other, which facilitates guiding the clamping sleeve to rotate to a vertical position.

[0031] 2. This environmental monitoring water quality sample sealing device can achieve continuous sampling and sealing. After the test tube is inserted into the holder in front of the first rotating plate, the first rotating plate rotates 120 degrees clockwise, and the second rotating plate rotates 180 degrees at the same time. After water is introduced into the water storage cylinder on the right and the stirring operation is completed, water can be introduced into the test tube. After the sampling operation is completed, the first rotating plate continues to rotate 120 degrees clockwise. Then, it can be used in conjunction with the second electric telescopic column and the sealing machine to complete the sealing operation.

[0032] 3. This environmental monitoring water sample sealing device can achieve the purpose of sealing and cleaning at the same time. When the test tube containing the sample is moved to the bottom of the sealing machine, the water storage tank containing the remaining water will be moved to the bottom of the water injection pipe. After the water in the storage tank is drained, clean water can be introduced into the storage tank. At the same time, the stirring rod rotates to facilitate automatic cleaning of the storage tank. This will prevent the water in the previous tank from interfering with the water in the next tank, making the subsequent test results more accurate, which is beneficial to environmental monitoring.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 7 The present invention provides a technical solution: a water quality sample sealing device for environmental monitoring, including a support platform 1, a first rotating plate 6 and a second rotating plate 8 rotatably connected to the top of the support platform 1, a support tube 7 fixed to the outer side of the first rotating plate 6, water storage cylinders 9 symmetrically fixed to both sides of the second rotating plate 8, a stirring rod 10 rotatably connected to the inner side of the water storage cylinder 9, the stirring rod 10 passing through one side of the water storage cylinder 9 and connected to a connecting mechanism 11, a rotating shaft 16 passing through the second rotating plate 8, and second locking blocks 17 symmetrically fixed to both ends of the rotating shaft 16, the second locking blocks 17 being engaged and connected to the connecting mechanism 11.

[0043] A first bracket 18 is fixed on one side of the upper surface of the support platform 1. A drainage pipe 19 is fixed on the first bracket 18. A water injection pipe 20 is fixed on the top of the first bracket 18. A rotary valve 21 is rotatably connected to the inner side of the water injection pipe 20. A linkage rotation mechanism 22 is fixed on the top of the second rotating plate 8. The linkage rotation mechanism 22 passes through the front side of the water injection pipe 20 and is connected to the rotary valve 21.

[0044] A second bracket 23 is fixed on the other side of the upper surface of the support platform 1. A second electric telescopic column 24 is fixed on the top of the second bracket 23. A sealing machine 25 is fixed on the bottom of the second electric telescopic column 24.

[0045] In this embodiment, as Figure 1 As shown, a first motor 2 is fixed to the bottom of the support platform 1, and the top of the first motor 2 is connected to the main sprocket 3. A second rotating plate 8 is fixed to the top of the main sprocket 3. The first rotating plate 6 passes through the top of the support platform 1 and is connected to the driven sprocket 5. A chain 4 is wound around the outside of the main sprocket 3 and the driven sprocket 5. The diameter of the main sprocket 3 is larger than the diameter of the driven sprocket 5. The main sprocket 3 can rotate under the action of the first motor 2, thereby driving the second rotating plate 8 to rotate. The chain 4 and the driven sprocket 5 can be used together to drive the first rotating plate 6 to rotate.

[0046] In this embodiment, as Figure 1 As shown, there are three holders 7, and the three holders 7 are evenly distributed on the first rotating plate 6. The first rotating plate 6 can rotate to facilitate the use of the three holders 7 in turn. Each holder 7 can hold a test tube. While sampling with the previous test tube, the next test tube can be inserted into the corresponding holder 7. While sealing the previous test tube, the next test tube can be used for sampling.

[0047] In this embodiment, as Figure 1 , Figure 2 and Figure 7 As shown, the connecting mechanism 11 includes a first locking block 1101, which is fixed to the inner end of the stirring rod 10. The inner side of the first locking block 1101 is connected to the abutment block 1103 through a compression spring 1102, and the outer side of the first locking block 1101 is engaged with a sleeve 1104. The first locking block 1101 is composed of a square block and a round rod. After the second locking block 17 is fully inserted into the sleeve 1107, the second locking block 17 will be fully retracted into the sleeve 1104. At this time, the square block on the first locking block 1101 is engaged with the sleeve 1104, and the abutment block 1103 is pressed against the sleeve 1104 under the action of the compression spring 1102. Then, the rotation of the second locking block 17 can drive the sleeve 1107, the sleeve 1104, the first locking block 1101 and the stirring rod 10 to rotate as a whole.

[0048] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, support rings 1105 are symmetrically fixed on both sides of the top of the second rotating plate 8. The sleeve 1104 passes through the support rings 1105 and is connected to the ferrule 1107. A protruding ring 1106 is fixed on the outer side of the sleeve 1104. The support rings 1105 support and limit the sleeve 1104. After the second locking block 17 is fully inserted into the ferrule 1107, the ferrule 1107 will rotate with the rotation of the first locking block 1101, thereby driving the sleeve 1104 and the first locking block 1101 to rotate.

[0049] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the top and bottom of the sleeve 1107 are both fixed with a first magnet 1108. The top two sides of the second rotating plate 8 are symmetrically fixed with second magnets 12. After the second locking block 17 leaves the sleeve 1107, the stop block 1103 will automatically spring open under the action of the compression spring 1102, thereby pushing the sleeve 1104 open. At this time, the sleeve 1104 separates from the block on the first locking block 1101. The sleeve 1104 and the round rod on the first locking block 1101 can rotate relative to each other. The first magnet 1108 and one of the second magnets 12 attract each other, and the sleeve 1107 can automatically rotate to a vertical state. Then the second locking block 17 can be smoothly locked into the sleeve 1107.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, a second motor 13 is fixed on one side of the second rotating plate 8, and the output end of the second motor 13 is connected to the first gear 14. The top of the first gear 14 is meshed with the second gear 15, and a rotating shaft 16 is fixed on the inner side of the second gear 15. The first gear 14 can rotate under the action of the second motor 13, thereby driving the second gear 15 to rotate, thereby driving the rotating shaft 16 to rotate, thereby driving the two second locking blocks 17 to rotate.

[0051] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the linkage rotation mechanism 22 includes a support column 2201, which is fixed to the top of the second rotating plate 8. A disc 2202 is fixed to the top of the support column 2201, and racks 2203 are symmetrically fixed on both sides of the disc 2202. The rotation of the second rotating plate 8 can drive the support column 2201 and the disc 2202 to rotate. After the rack 2203 is meshed with the third gear 2204, the third gear 2204 will rotate with the rotation of the disc 2202.

[0052] In this embodiment, as Figure 1 , Figure 3 and Figure 6As shown, a support bar 2205 is fixed to the front side of the water injection pipe 20. A third gear 2204 is rotatably connected to the bottom of the support bar 2205. The third gear 2204 is meshed with the rack 2203. The third gear 2204 passes through the support bar 2205 and is connected to the chain drive device 2206. The output end of the chain drive device 2206 is connected to the worm 2207. A worm wheel 2208 is meshed with one side of the worm 2207. The worm wheel 2208 passes through the front side of the water injection pipe 20 and is connected to the rotary valve 21. The rotation of the third gear 2204 can drive the chain drive device 2206 to operate, thereby driving the worm 2207 to rotate, which in turn drives the worm wheel 2208 to rotate, which in turn drives the rotary valve 21 to rotate, thus facilitating the control of the opening and closing of the water injection pipe 20.

[0053] According to another aspect of the present invention, a tracking method for a water quality sample sealing device for environmental monitoring includes the following steps:

[0054] S1. Insert the test tube into the holder 7 in front of the first rotating plate 6. While the first rotating plate 6 rotates 120 degrees clockwise, the second rotating plate 8 rotates 180 degrees. After the water to be sampled is passed into the water storage cylinder 9 on the right, the stirring rod 10 rotates to automatically stir the water. After the water is passed into the test tube, the first rotating plate 6 continues to rotate 120 degrees clockwise. At this time, the water storage cylinder 9 containing the remaining water reaches the bottom of the water injection pipe 20. After draining the water in the water storage cylinder 9, clean water can be passed into the water storage cylinder 9 for cleaning.

[0055] S2. After the second card block 17 leaves the card sleeve 1107, the card sleeve 1107 automatically pops open. When used with the first magnet 1108 and the second magnet 12, the card sleeve 1107 can automatically rotate to a vertical position.

[0056] S3. While cleaning the water storage tank 9, the second electric telescopic column 24 and the sealing machine 25 can be used to complete the sealing process of the test tube.

[0057] S4. The rotation of the second rotating plate 8 can drive the support column 2201 and the disc 2202 to rotate. After the rack 2203 is meshed with the third gear 2204, the third gear 2204 rotates, thereby driving the chain drive device 2206, worm 2207, worm wheel 2208 and rotary valve 21 to rotate. After the water storage tank 9 leaves the bottom of the water injection pipe 20, the rotary valve 21 automatically closes. After the water storage tank 9 rotates to the bottom of the water injection pipe 20, the rotary valve 21 automatically opens.

[0058] The method of use and advantages of this invention: The working process of this water quality sample sealing device for environmental monitoring is as follows:

[0059] like Figures 1 to 7As shown: First, the test tube is inserted into the holder 7 on the front side of the first rotating plate 6. The main sprocket 3, chain 4, and driven sprocket 5 rotate. While the second rotating plate 8 rotates 180 degrees, the first rotating plate 6 rotates 120 degrees clockwise, allowing the water to be sampled to flow into the water storage cylinder 9 on the right. Then, the first gear 14 rotates, thereby driving the second gear 15, rotating shaft 16, and second locking block 17 to rotate. The rotation of the second locking block 17 drives the locking sleeve 1107, the first locking block 1101, and the stirring rod 10 to rotate, thus... After stirring the water to be sampled and opening the valve at the bottom of the holder 7 to allow water to flow into the test tube, the second rotating plate 8 rotates 180 degrees, and the first rotating plate 6 rotates 120 degrees clockwise. At this point, the test tube containing the sample reaches below the sealing machine 25. Using the second electric telescopic column 24 and the sealing machine 25, the test tube can be automatically sealed. Simultaneously, the water storage cylinder 9, filled with water, reaches below the water injection pipe 20. After draining the water from the storage cylinder 9, clean water can be introduced into the storage cylinder 9 through the water injection pipe 20. Then, stirring... The rod 10 rotates to facilitate automatic cleaning of the water storage tank 9. The drain pipe 19 can be used to drain water. The above operation is repeated to facilitate continuous sampling and packaging, as well as alternating use and cleaning of the two water storage tanks 9. When the second rotating plate 8 rotates, it can drive the support column 2201 and the disc 2202 to rotate. After the rack 2203 meshes with the third gear 2204, the third gear 2204 starts to rotate, thereby driving the chain drive device 2206, the worm 2207, the worm wheel 2208, and the rotary valve. After the water storage cylinder 9 rotates away from below the water injection pipe 20, the rotary valve 21 is in a horizontally closed state. After the water storage cylinder 9 rotates to below the water injection pipe 20, the rotary valve 21 is in a vertically open state. After the second locking block 17 leaves the sleeve 1107, the sleeve 1104 and the sleeve 1107 automatically pop open. The first magnet 1108 and the second magnet 12 can be used together to help the sleeve 1107 rotate to a vertical state, so that the second locking block 17 can be smoothly locked into the sleeve 1107.

[0060] In summary, this water sample sealing device for environmental monitoring achieves the goals of automatic stirring, continuous sampling and sealing, and simultaneous cleaning during sealing, thus meeting people's usage needs.
