Description

Technical Field

[0001] This utility model relates to the technical field of gas and water sample collection devices, and in particular to a high-efficiency gas and water sample collection device. Background Technology

[0002] The gas and water sample collection device is used to collect gas and liquid samples synchronously, accurately, and without interference. Its core function is to ensure that the original state of physical properties (such as temperature, pressure, and flow rate) and chemical components (such as dissolved oxygen, volatile organic compounds, and heavy metal ions) is completely preserved during the sample collection process through optimized sampling head design, dynamic flow control system, and real-time environmental parameter monitoring module. When gas and water sample collection devices are used in scenarios such as environmental monitoring and industrial testing, traditional sampling devices often adopt a single-channel design, which can only collect water or gas samples at a time. For example, existing sampling equipment usually has a fixed collection port, and sample collection is completed by manually plugging and unplugging it. However, such devices can only operate on a single type of sample (such as pure water or pure gas) and cannot simultaneously meet the needs of gas and water dual collection.

[0003] Therefore, to address the problem of inconvenience in classifying and collecting multiple types of gas and water samples in scenarios involving the classification and collection of multiple samples, a high-efficiency gas and water sample collection device can be designed. When using this device to collect water samples, activating one side's lifting mechanism inserts the water-filling end of the pumping mechanism into the inlet pipe of one of the collection tanks on the same side. After the water sample collection is completed, activating the lifting mechanism again disengages the water-filling end from the inlet pipe. When collecting gas samples, activating the other side's lifting mechanism inserts the air-filling end of the air-collecting mechanism into the air-filling pipe of one of the collection tanks on the same side. After the gas sample collection is completed... Reactivating the lifting mechanism detaches the inflation end from the air inlet pipe. When collecting different samples, the drive guide seat moves the air extraction and water extraction mechanisms to the next collection tank position. The collection operation is then performed as described above. In summary, the integrated gas and water sampling design significantly improves sampling efficiency. By moving the guide seat laterally and adjusting the lifting mechanism vertically, different collection tanks can be quickly switched, enabling continuous collection of multiple sample categories. This achieves high efficiency, accuracy, and convenience in gas and water sample collection, making it particularly suitable for scenarios requiring rapid collection of multiple samples, such as environmental monitoring and industrial testing. It possesses significant technical advantages and practical application value. Utility Model Content

[0004] To overcome the problem that traditional sampling devices can only collect water or gas samples, existing sampling equipment usually has a fixed collection port, and the sample collection is completed by manually plugging and unplugging, which is inefficient. Therefore, it is inconvenient to collect multiple types of gas and water samples in scenarios where multiple samples are collected separately.

[0006] Preferably, when using this gas-water sample collection device, when collecting water samples, activating one side of the lifting mechanism will cause the water-filling end of the pumping mechanism to be inserted into the inlet pipe of one of the collection tanks on the same side. After the water sample collection is completed, the lifting mechanism is activated again to disengage the water-filling end from the inlet pipe. When collecting gas samples, activating the other side of the lifting mechanism will cause the air-filling end of the gas-pumping mechanism to be inserted into the air-pumping pipe of one of the collection tanks on the same side. After the gas sample collection is completed, the lifting mechanism is activated again to disengage the air-pumping end from the air-pumping pipe. When collecting different samples, the drive guide seat will move the gas-pumping mechanism and the water-pumping mechanism to the position of the next collection tank. The collection operation is carried out according to the above. In summary, the integrated gas-water dual-sampling design greatly improves the sampling efficiency. By moving the guide seat laterally and adjusting the lifting mechanism vertically, different collection tanks can be quickly switched to achieve continuous collection of multiple sets of samples. This achieves high efficiency, accuracy, and convenience in gas-water sample collection, and is especially suitable for scenarios such as environmental monitoring and industrial testing that require rapid collection of multiple sets of samples.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figure 1 and Figure 3 This utility model provides an embodiment of a high-efficiency gas-water sample collection device, including a collection trolley 1, a receiving box 2 fixedly installed inside the collection trolley 1, a guide seat 3 that can slide laterally on the top of the receiving box 2, a water pumping mechanism on one side of the guide seat 3, an air pumping mechanism on the other side, receiving cavities symmetrically opened on both sides of the receiving box 2, multiple sets of pull-out boxes 4 installed inside the receiving cavities, and a collection tank 5, with a collection tank 5 installed inside each set of pull-out boxes 4. The air-filling end of the air pumping mechanism is installed in the air inlet pipe of one collection tank 5, and the water-filling end of the water pumping mechanism is installed in the water inlet pipe of the other collection tank 5. Lifting mechanisms are respectively installed on both sides of the guide seat 3, and the telescopic ends of the lifting mechanisms on both sides are fixedly connected to the air-filling end of the air pumping mechanism and the water-filling end of the water pumping mechanism, respectively.

[0017] Please see Figure 3 and Figure 7Multiple guide grooves 6 are formed on the bottom wall of the receiving cavity, each corresponding to a pull-out box 4. Guide rods 7 are fixedly installed inside the guide grooves 6, and guide blocks 8 are slidably fitted onto the side walls of the guide rods 7. The top of the guide blocks 8 is fixedly connected to the bottom of the pull-out box 4. A magnetic block 9 is fixedly installed on one side of the top of the outer wall of each pull-out box 4. Multiple metal rods 10 are rotatably installed on the top of the outer wall of the receiving box 2. The metal rods 10 are magnetically connected to the magnetic blocks 9. The magnetic attraction can be released by manually rotating the metal rods 10, and then the pull-out box 4 can be pulled out to remove the collection tank 5. The pull-out box 4 can then drive the guide blocks 8 along the guide rods 7. The guide seat 3 slides out smoothly. Automatic winding wheels 11 are symmetrically arranged on the top of the guide seat 3. Electrically controlled valves 12 are respectively installed on the air inlet pipe of one collection tank 5 and the water inlet pipe of the other collection tank 5. The automatic winding wheels 11 can automatically store the water suction pipe 15 and the air suction pipe 19 to avoid messy wiring. The lifting structure includes an electrically controlled push rod 13 and a connecting rod 14. Electrically controlled push rods 13 are symmetrically fixed on both sides of the guide seat 3. The telescopic end of the electrically controlled push rod 13 is fixedly connected to the connecting rod 14. The telescopic end of each electrically controlled push rod 13 is fixedly sleeved on the outer wall of the water filling pipe 18 and the air filling pipe 22 through the connecting rod 14 to realize vertical lifting control.

[0018] Please see Figure 4 and Figure 5The pumping mechanism includes a pumping pipe 15, a pumping nozzle 16, a pumping pump 17, and a filling pipe 18. The pumping pump 17 is fixedly installed on one side of the guide seat 3. The pumping pipe 15 is wound inside the automatic winding wheel 11 on the same side. The pumping nozzle 16 is fixedly installed at the pumping end of the pumping pipe 15. The water outlet end of the pumping pipe 15 is fixedly connected to the water inlet end of the pumping pump 17. The filling pipe 18 is fixedly installed at the water outlet end of the pumping pump 17. One end of the connecting rod 14 on the same side is fixedly sleeved on the filling pipe. The lower end of the water filling pipe 18 is fitted inside the upper end of the water inlet pipe. Activating the electric control push rod 13 on one side moves the water filling pipe 18 downwards via the connecting rod 14, inserting it into the water inlet pipe of the corresponding collection tank 5. The operator holds the water pump head 16 and inserts it into the water body to be collected, then starts the water pump 17. The water enters the water pump 17 through the water pump pipe 15 and is then filled into the collection tank 5 through the water filling pipe 18. After collection is complete, the electric control valve 12 on the water inlet pipe is closed. The retraction of the control rod 13 causes the water filling pipe 18 to detach from the water inlet pipe. The air extraction mechanism includes an air extraction pipe 19, an air extraction nozzle 20, an air pump 21, and an air filling pipe 22. The air pump 21 is fixedly installed on the other side of the guide seat 3. The air extraction pipe 19 is wound inside the automatic winding wheel 11 on the same side. The air extraction nozzle 20 is fixedly installed at the air extraction end of the air extraction pipe 19. The air outlet end of the air extraction pipe 19 is fixedly connected to the air inlet end of the air pump 21. The air filling pipe 22 is fixedly installed at the air outlet end of the air pump 21. 2. One end of the connecting rod 14 on the same side is fixedly sleeved on the outer wall of the inflation tube 22, and the lower end of the inflation tube 22 is sleeved inside the upper end of the air inlet tube. When the other side is activated, the electric control push rod 13 drives the inflation tube 22 to be inserted into the air inlet tube of the collection tank 5 through the connecting rod 14. The suction gun head 20 draws out the gas sample, which enters the suction pump 21 through the suction tube 19, and then fills the collection tank 5 through the inflation tube 22. After completion, the air inlet tube electric control valve 12 is closed, and the inflation tube 22 rises and disengages.

[0019] Please see Figure 2 and Figure 6 A slide rail 23 is fixedly installed on the top of the container 2. The bottom of the guide seat 3 is fitted inside the slide rail 23. A drive motor 24 is fixedly installed on the outer wall of the guide seat 3. A drive shaft 25 is installed at the output end of the drive motor 24. The drive shaft 25 rotates through the inside of the guide seat 3. A drive gear 26 is fixedly installed at the end of the drive shaft 25. A guide tooth plate 27 is fixedly installed on one side of the slide rail 23. The drive gear 26 meshes with the guide tooth plate 27. When the drive motor 24 is started, it drives the drive gear 26 to rotate through the drive shaft 25. Since the drive gear 26 meshes with the guide tooth plate 27, the guide seat 3 is driven to move horizontally by utilizing the gear-tooth plate meshing characteristics. With the symmetrically opened container cavity structure on both sides of the container 2, the water pumping or air pumping mechanism can be accurately positioned among multiple sets of pull-out boxes 4.

[0020] When using this gas-water sample collection device, the working principle of the high-efficiency gas-water sample collection device is as follows: The device uses a collection trolley 1 as a carrier, and a receiving box 2 is fixedly installed inside the trolley. The top of the receiving box 2 is connected to a guide seat 3 that can slide laterally through a slide rail 23. The bottom of the guide seat 3 is embedded in the slide rail 23, and a drive motor 24 is fixed on the outer wall. Its output end is connected to a drive gear 26 through a drive shaft 25. The gear meshes with a guide tooth plate 27 on one side of the slide rail 23 to realize the horizontal linear movement of the guide seat 3.

[0021] The guide seat 3 integrates a water pumping mechanism and an air pumping mechanism on both sides: the water pumping mechanism on the left consists of a water pumping pipe 15, a water pumping nozzle 16, a water pump 17, a water filling pipe 18, and an automatic winding wheel 11. The water pumping pipe 15 is wound around the winding wheel and extends to the water pumping nozzle 16. The water outlet is connected to the water inlet of the water pump 17. The water outlet of the water pump 17 is connected to the water inlet of the collection tank 5 through the water filling pipe 18. The air pumping mechanism on the right is similar. The air pumping pipe 19 is connected to the air pumping nozzle 20 and the air pump 21 through the winding wheel. The air outlet of the air pump 21 is connected to the air inlet of the collection tank 5 through the air filling pipe 22. The two sets of lifting mechanisms are symmetrically arranged on both sides of the guide seat 3. The telescopic end of the electric control push rod 13 on each side is fixedly sleeved on the outer wall of the water filling pipe 18 and the air filling pipe 22 through the connecting rod 14 to realize vertical lifting control.

[0022] When collecting water samples, activate the electric control push rod 13 on one side, which drives the water filling pipe 18 downward through the connecting rod 14 and inserts it into the inlet pipe of the corresponding collection tank 5. The staff holds the water pump head 16 and inserts it into the water body to be sampled, and starts the water pump 17. The water enters the water pump 17 through the water pump pipe 15 and is filled into the collection tank 5 through the water filling pipe 18. After the collection is completed, close the electric control valve 12 on the inlet pipe, and the electric control push rod 13 retracts to disengage the water filling pipe 18 from the inlet pipe.

[0023] When gas collection is performed, the other side of the electric control push rod 13 is activated, which drives the inflation tube 22 to be inserted into the air inlet tube of the collection tank 5 through the connecting rod 14. The suction gun head 20 draws out the gas sample, which enters the suction pump 21 through the suction tube 19, and then fills the collection tank 5 through the inflation tube 22. After completion, the air inlet tube electric control valve 12 is closed, the inflation tube 22 rises and disengages, and the automatic winding wheel 11 can automatically store the water suction tube 15 and the suction tube 19 to avoid messy wiring.

[0024] To meet the needs of multiple collection tanks, the drive motor 24 drives the drive gear 26 to rotate via the drive shaft 25. Utilizing the gear-tooth plate meshing characteristics, the guide seat 3 moves horizontally. In conjunction with the symmetrically opened receiving cavities on both sides of the receiving box 2, the pumping or air-pumping mechanism is precisely positioned among multiple sets of pull-out boxes 4. Each set of pull-out boxes 4 contains a collection tank 5. The bottom is slidably connected to the guide groove 6 on the bottom wall of the receiving cavity via the guide block 8. The guide rod 7 ensures that the pull-out box 4 is pulled out smoothly. The magnetic block 9 on the top of the outer wall of the pull-out box 4 magnetically engages with the rotating metal rod 10 on the top of the outer wall of the receiving box 2, achieving stable positioning and convenient unlocking of the pull-out box 4. When it is necessary to remove the collected sample, the magnetic attraction can be released by manually rotating the metal rod 10, and then the pull-out box 4 can be pulled out to remove the collection tank 5.

[0025] In summary, the device offers significant advantages: Firstly, the integrated air-water dual-sampling design greatly improves sampling efficiency. Through the lateral movement of the guide seat 3 and the vertical adjustment of the lifting mechanism, different collection tanks 5 can be quickly switched, enabling continuous collection of multiple sets of samples. Secondly, the magnetic fixing and sliding structure of the guide rod 7-guide groove 6 ensure smooth pulling and precise positioning of the pull-out box 4. Combined with the electrically controlled valve 12 for sealing the water or air inlet pipe, this effectively prevents cross-contamination and leakage of samples. Thirdly, the automatic winding wheel 11 enables automatic retraction and extension of the water or air extraction pipe 15, avoiding pipe entanglement. Fourth, the drive motor 24 and gear-tooth plate transmission mechanism ensure the precise and stable movement of the guide seat 3, adapting to different sampling position requirements. Fifth, the separate design of the pull-out box 4 and the collection container 5 facilitates sample transfer and post-processing. The magnetic limit of the metal rod 10 ensures storage stability and supports rapid retrieval and placement. In summary, through structural innovation and functional integration, this device achieves high efficiency, accuracy and convenience in gas and water sample collection. It is especially suitable for scenarios such as environmental monitoring and industrial testing that require rapid collection of multiple sets of samples, and has significant technical advantages and practical application value.

[0026] Through the above steps, when using this gas-water sample collection device, when collecting water samples, activating one side of the lifting mechanism will cause the water-filling end of the pumping mechanism to be inserted into the inlet pipe of one of the collection tanks 5 on the same side. After the water sample collection is completed, the lifting mechanism is activated again to cause the water-filling end to detach from the inlet pipe. When collecting gas samples, activating the other side of the lifting mechanism will cause the air-filling end of the air-pumping mechanism to be inserted into the air-pumping pipe of one of the collection tanks 5 on the same side. After the gas sample collection is completed, the lifting mechanism is activated again to cause the air-filling end to detach from the air-pumping pipe. When collecting different samples, driving the guide seat 3 will cause the air-pumping mechanism and the water-pumping mechanism to move to the position of the next collection tank 5. The collection operation is carried out according to the above. In summary, the integrated gas-water dual-sampling design greatly improves the sampling efficiency. By moving the guide seat 3 laterally and adjusting the lifting mechanism vertically, different collection tanks 5 can be quickly switched to achieve continuous collection of multiple sets of samples. This achieves high efficiency, accuracy and convenience in gas-water sample collection, and is especially suitable for scenarios such as environmental monitoring and industrial testing that require rapid collection of multiple sets of samples. It has significant technical advantages and practical application value.
