Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically a portable water quality sampler. Background Technology

[0002] Currently, environmental monitoring systems, petrochemicals, hydrology and water conservancy, water supply companies, sewage treatment plants, thermal power plants, steel enterprises, university research and teaching, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, transportation environmental monitoring, environmental research and other departments need to conduct on-site water sampling.

[0003] In production practice, to meet monitoring needs, it is often necessary to sample water sources at different times, locations, and even depths. However, existing samplers often have a single-chamber sample chamber, meaning that only one sample can be collected per operation. After collection, the sample chamber often needs to be opened to collect the collected sample before the next sampling, which is not only time-consuming and labor-intensive, but also detrimental to improving sampling efficiency, and can easily cause sample contamination. Utility Model Content

[0004] This utility model discloses a portable water quality sampler, which solves the technical problems of low sampling efficiency and easy sample contamination in existing samplers. It features a reasonable structure, high sampling efficiency, and avoidance of sample contamination. The technical solution adopted is as follows: A portable water sampler, comprising: A sampling pump, wherein the inlet of the sampling pump is connected to the sampling port, and is used to draw up the sample liquid; The water inlet of the water inlet is movably connected to the outlet of the sampling pump via an adapter, and the outlet of the water inlet is used to inject liquid into the sample bottle. The water-dispensing drive is used to drive the water-dispensing nozzle to dispense liquid into different sample bottles; A first housing, comprising a plurality of cavities for accommodating sample vials.

[0005] Based on the above technical solution, the inlet of the water separator is movably connected to the outlet of the sampling pump via a rotary joint, and the water separator drive is used to drive the water separator to rotate in order to inject liquid into the circumferentially arranged sample bottles. Alternatively, the inlet of the water separator is connected to the outlet of the sampling pump via a flexible hose, and the water separator drive is used to drive the water separator to move in the horizontal plane in order to inject liquid into the sample bottles.

[0006] Based on the above technical solution, a second housing is also included. The upper part of the first housing has a stop portion for supporting the second housing. The sampling pump and water distribution drive are fixed in the inner cavity of the second housing. The water distribution nozzle is rotatably connected to the bottom surface of the second housing, and the outlet of the water distribution nozzle extends out of the second housing.

[0007] Based on the above technical solution, a positioning pin is also included, which passes laterally through the first housing and is inserted into the second housing to position the first housing and the second housing.

[0008] Based on the above technical solution, the bottom of the second housing also includes several support legs that can extend into the upper part of the inner cavity of the first housing.

[0009] Based on the above technical solution, a limiting block is also provided in the second housing, the limiting block abutting laterally against the water distributor to provide resistance to the rotation of the water distributor.

[0010] Based on the above technical solution, it also includes a liquid level identification device and a flow meter. The liquid level identification device is used to identify whether there is sample liquid passing through the pipe section connected to the water inlet of the water distributor. The flow meter is designed so that when the liquid level identification device detects that sample liquid is passing through, the flow meter starts to measure the amount of sample liquid flowing through.

[0011] Based on the above technical solution, it also includes a controller and a power supply fixed in the second housing. The power supply also includes a charging interface. The controller is electrically connected to the power supply, the sampling pump and the water distribution drive respectively. The power supply is used to supply power to the controller, the sampling pump and the water distribution drive.

[0012] Based on the above technical solution, a third housing is also included, which is covered outside the second housing and can be detachably connected to the first housing via a locking fastener.

[0013] Based on the above technical solution, the top of the third housing and / or the bottom of the first housing are symmetrically provided with multiple hooks for moving and transferring the sampler.

[0014] Beneficial effects This invention features a rationally designed structure. The water-dispensing nozzle moves under the action of water separation, injecting liquid into different sample bottles separately. This allows for the collection of multiple sample solutions in a single operation, resulting in high sampling efficiency, saving time and costs, and avoiding frequent opening of the sample chamber, thus saving time and effort. Simultaneously, the collected sample solution can be directly collected in the sample bottle, completing sample dispensing during collection, saving time and effort, and preventing mixing of samples from consecutive collections, which helps improve detection accuracy. Furthermore, the sampling pump, water separation drive, and other electronic components are encapsulated within the second housing, preventing harsh external environments from affecting the sampling operation and ensuring continuous and stable operation of the sampler.

[0015] In this invention, the upper part of the first housing has a stop portion for supporting the second housing, and also includes a positioning pin. This facilitates the assembly and disassembly of the first and second housings while ensuring their proper positioning. Furthermore, the second housing is provided with several feet, which facilitates the placement of the second housing when opening the first housing to retrieve or store sample vials, making it convenient to use. A third housing is also included, which covers the second housing and is connected to the first housing via a snap-fit ​​mechanism, thus protecting the second housing. Hooks on the outside of the first and third housings facilitate the movement and transfer of the sampler, making it convenient to use. Attached Figure Description

[0022] like Figures 1-5A portable water sampler, as shown, includes a controller 10, a sampling pump 1, a water distributor 2, a water distributor drive, a second housing 6, and a first housing 4. Sampling pump 1 has its inlet connected to sampling port 200 and is used to draw sample liquid. In this embodiment, sampling pump 1 is a peristaltic pump. Sampling port 200 extends laterally to the outside of the sampler and can be connected to a sampling hose for extracting samples.

[0023] Water separator 2 has its inlet connected to the outlet of sampling pump 1 via a rotary joint. A water-distributing drive is used to rotate the water separator to dispense liquid into the circumferentially arranged sample bottles. The rotary joint is existing technology and can be selected by those skilled in the art as needed, allowing the inlet of water separator 2 to be connected to and rotate relative to the outlet of sampling pump 1. Figure 4 As shown, the water distribution drive (not shown) includes a water distribution motor. The rotating shaft of the water distribution motor transmits rotational motion to the water distribution nozzle 2 via a belt drive assembly. The belt drive assembly is existing technology and will not be described in detail here. It also includes a limiting block 8 disposed within the second housing 6. The limiting block 8 laterally abuts against the water distribution nozzle 2. Specifically, the water distribution nozzle 2 includes a vertically extending inlet pipe, the end of which forms the water inlet of the water distribution nozzle 2. The limiting block 8 laterally abuts against this inlet pipe to provide resistance to the rotation of the water distribution nozzle 2, ensuring the water distribution nozzle 2 maintains a good position.

[0024] like Figure 4 As shown, the controller 10, sampling pump 1, and water distribution drive are fixed in the inner cavity of the second housing 6. The water distribution nozzle 2 is rotatably connected to the bottom surface of the second housing 6, and the outlet of the water distribution nozzle 2 extends out of the second housing 6 to facilitate the injection of liquid into multiple sample bottles.

[0025] As shown in the figure, the first housing 4 includes several cavities 100 for accommodating sample bottles. Specifically, two perforated plates arranged vertically are fixed inside the first housing 4. Multiple through holes are arranged circumferentially on the perforated plates. Thus, the through holes corresponding to the vertical positions form cavities 100 for accommodating sample bottles, and the sample bottles can be easily inserted into the cavities 100.

[0026] like Figure 5 As shown, the upper part of the first housing 4 has a stop portion 41 for supporting the second housing 6. The stop portion 41 extends in an annular shape, and the corresponding position of the lower part of the second housing 6 is provided with an annularly extending flange 61. The flange 61 can abut against the stop portion 41 downwards, so that the first housing 4 supports the second housing 6 upwards.

[0027] like Figure 2 and 3As shown, it includes a positioning pin 7, which passes laterally through the first housing 4 and is inserted into the second housing 6 to position the first housing 4 and the second housing 6, so that the outlet of the water nozzle 2 and the sample bottle have a good relative position.

[0028] In addition, the bottom of the second housing 6 also includes several support feet 62 that can extend into the upper part of the inner cavity of the first housing 4, which makes it convenient to place the second housing 6 when opening the first housing 4 to take out or put in the sample bottle, making it easy to use.

[0029] The system includes a liquid level identification device 9 and a flow meter. The liquid level identification device 9 is used to identify whether there is sample liquid passing through the pipe section connected to the inlet of the water distributor 2. The liquid level identification device 9 includes a liquid level sensor, which is existing technology and will not be described in detail here. The flow meter is designed so that when the liquid level identification device 9 detects that sample liquid is passing through, the flow meter starts to measure the amount of sample liquid flowing through, so as to quantitatively inject sample liquid into the sample bottle. It is convenient to use and helps to accurately control the sampling volume.

[0030] In this embodiment, the second housing 6 includes a sealed inner cavity to protect the electronic components. The inner cavity of the second housing 6 is also provided with a power supply 11. The power supply 11 has a charging interface 111 formed on the top surface of the second housing 6. The controller 10 is electrically connected to the power supply 11, the sampling pump 1, the water distribution drive, the liquid level identification device 9 and the flow meter respectively. The power supply 11 is used to supply power to the controller 10, the sampling pump 1, the water distribution drive, the liquid level identification device 9 and the flow meter.

[0031] like Figure 1 and 2 As shown, it also includes a third housing 12 and a sealing ring 5. The third housing 12 covers the second housing 6 and can be detachably connected to the first housing 4 downwards via a locking member 13, as shown. Figure 5 As shown, the sealing ring 5 is fitted onto the upper part of the first housing 4, and the upper part of the first housing 4 is fitted into the third housing 12. When the locking member 13 connects the third housing 12 and the first housing 4, the inner cavity of the second housing 6 is sealed, thus preventing external water samples or debris from entering the sampler during sampling, ensuring good safety. The locking member 13 is existing technology and will not be described in detail here. In this embodiment, the locking member 13 includes two symmetrically arranged first latches and a combination lock latch. The first fixing members of the two first latches are fixed to the outside of the third housing 12, and the first movable members of the two first latches are hinged to the outside of the first housing 4. The combination lock latch includes a second fixing member, a second movable member, and a combination lock. The second fixing member is fixed to the outside of the third housing, and the sealing lock is fixed to the second fixing member. One end of the second movable member is hinged to the outside of the first housing, and the second end of the second movable member is engaged with the second fixing member.

[0032] like Figure 1As shown, the third housing 12 has a hook 14 at the top center and two ear plates symmetrically arranged on the top outer edge for easy installation of pull rings. The first housing 4 has two hooks symmetrically arranged at the bottom for moving and transporting the sampler, which is convenient to use.
