Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically a portable water quality testing device that can quickly collect samples. Background Technology

[0002] Water quality testing devices are instruments or equipment used to detect, analyze, or monitor the physical, chemical, or biological properties of water bodies. Simply put, they are "tools used to detect the quality of water or water quality parameters" to determine whether the water quality is safe, meets standards, or meets certain requirements for a particular purpose.

[0003] In the prior art, the sampling tubes of portable water quality testing devices that can quickly sample are designed to meet the needs of rapid sampling. Their sampling ports mostly adopt an open straight cylindrical structure and do not have any filter components for impurities in the water sample. Because the sampling port lacks a filter barrier, impurities will directly enter the sampling tube with the water sample, interfering with the subsequent testing results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a portable water quality testing device that enables rapid sampling.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A portable water quality testing device for rapid sampling includes a sampling instrument, a micro water pump, a sampling tube, and a display panel. The sampling tube is externally equipped with a filter device, which includes a fixing ring. The inside of the fixing ring is fixedly connected to the sampling tube. One end of the fixing ring is fixedly connected to an adsorption ring. One end of the adsorption ring is magnetically connected to a magnetic ring. One end of the magnetic ring is fixedly connected to a mounting ring. An outer cylinder is fixedly connected to the arc surface of the mounting ring. A through plate is fixedly connected inside the outer cylinder, and a filter screen is fixedly connected inside the through plate.

[0007] The effect achieved by the above components is that the magnetic ring and the adsorption ring are attracted together to fix the position of the outer cylinder, thereby fixing the position of the filter screen driven by the through plate.

[0008] Preferably, a plurality of anti-slip rings are fixedly connected to the arc surface of the outer cylinder, and the plurality of anti-slip rings are evenly distributed on the outer cylinder.

[0009] The effect achieved by the above components is to increase friction, thus achieving the effect of the anti-slip ring.

[0010] Preferably, an assembly ring is fixedly connected to one end of the outer cylinder.

[0011] The effect achieved by the above components is that the assembly ring is fixed on the outer cylinder.

[0012] Preferably, a sealing ring is slidably connected inside the assembly ring.

[0013] The effect achieved by the above components is that the sealing ring and the assembly ring are compatible.

[0014] Preferably, a connecting ring is fixedly connected inside the sealing ring, and the inside of the connecting ring is fixedly connected to the sampling tube.

[0015] The effect achieved by the above components is that the sealing ring is fixed on the connecting ring, and the connecting ring is fixed on the sampling tube.

[0016] Preferably, the sampling and testing instrument is provided with a lifting device on its exterior. The lifting device includes a fixing block, one side of which is fixedly connected to the sampling and testing instrument, and round rods are fixedly connected to both sides of the fixing block.

[0017] The aforementioned components achieve the following effect: the round rod is fixed on the fixing block, and the fixing block is fixed on the sampling and testing instrument.

[0018] Preferably, the circular rod has a rubber ring rotatably connected to its arc surface.

[0019] The effect achieved by the above components is that the rubber ring and the round rod are properly matched.

[0020] Preferably, a rotating ring is fixedly connected to the arc surface of the rubber ring, and a side plate is fixedly connected to the arc surface of the rotating ring.

[0021] The effect achieved by the above components is that the rubber ring and the side plate are fixed on the rotating ring.

[0022] Preferably, a pull frame is fixedly connected to one end of each of the two side plates.

[0023] The effect achieved by the above components is to fix the frame to the side panel.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. The filtration device allows the magnetic ring and adsorption ring to engage when the water sample needs to be filtered, achieving precise positioning of the outer cylinder. This positioning can be fixed by the through plate, ensuring the filter screen accurately covers the sampling port of the sampling tube, thus preventing impurities in the water sample from entering the sampling tube. This filtration device addresses the problem that traditional portable water quality testing devices, designed for rapid sampling, often use open, straight-cylinder sampling ports without any filtering components for impurities in the water sample. Because of this lack of a filter barrier, impurities can directly enter the sampling tube with the water sample, interfering with subsequent testing.

[0026] 2. With the lifting device, when the sampling and testing instrument needs to be taken out, pull the frame to rotate the side plate around the rod. After the frame is rotated to the appropriate angle, hold it to take out the sampling and testing instrument. The lifting device solves the problem that traditional portable water quality testing instruments that can quickly sample are mostly carried bare or rely on storage bags. When the instrument is not in use, the outer shell of the instrument must be held directly. The lack of a dedicated moving auxiliary structure increases the risk of the instrument being dropped and damaged. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0035] Example

[0036] like Figure 1 , Figure 3 and Figure 5 As shown, a portable water quality testing device for rapid sampling includes a sampling instrument 1, a micro water pump 4, a sampling tube 5, and a display panel 6. The sampling tube 5 is equipped with a filter device 2, and the sampling instrument 1 is equipped with a lifting device 3.

[0037] The specific setup and function of its filter device 2 and lifting device 3 will be explained below.

[0038] Reference Figure 2 As shown in this embodiment: the filter device 2 includes a fixing ring 201, the inside of which is fixedly connected to the sampling tube 5. One end of the fixing ring 201 is fixedly connected to an adsorption ring 202, one end of which is magnetically connected to a magnetic ring 203. One end of the magnetic ring 203 is fixedly connected to an mounting ring 204, and the arc surface of the mounting ring 204 is fixedly connected to an outer cylinder 205. A through plate 206 is fixedly connected inside the outer cylinder 205, and a filter screen 207 is fixedly connected inside the through plate 206. This achieves the effect of fixing the position of the outer cylinder 205 after the magnetic ring 203 and adsorption ring 202 are attracted together, thus fixing the position of the filter screen 207 by the through plate 206. Several anti-slip rings 208 are fixedly connected to the arc surface of the outer cylinder 205, and these anti-slip rings 208 are evenly distributed on the outer cylinder 205. This achieves the effect of increasing friction. One end of the outer cylinder 205 is fixedly connected to an assembly ring 209. This achieves the effect of fixing the assembly ring 209 to the outer cylinder 205. A sealing ring 210 is slidably connected inside the assembly ring 209, achieving a proper fit between the sealing ring 210 and the assembly ring 209. A connecting ring 211 is fixedly connected inside the sealing ring 210, and the interior of the connecting ring 211 is fixedly connected to the sampling tube 5. This achieves the effect of fixing the sealing ring 210 to the connecting ring 211, and fixing the connecting ring 211 to the sampling tube 5.

[0039] Reference Figure 4 As shown, in this embodiment: the lifting device 3 includes a fixing block 31, one side of which is fixedly connected to the sampling and detection instrument 1, and round rods 32 are fixedly connected to both sides of the fixing block 31. This achieves the effect of the round rods 32 being fixed to the fixing block 31, and the fixing block 31 being fixed to the sampling and detection instrument 1. A rubber ring 33 is rotatably connected to the arc surface of the round rod 32. This achieves the effect of the rubber ring 33 and the round rod 32 being compatible. A rotating ring 34 is fixedly connected to the arc surface of the rubber ring 33, and a side plate 35 is fixedly connected to the arc surface of the rotating ring 34. This achieves the effect of the rubber ring 33 and the side plate 35 being fixed to the rotating ring 34. A pull frame 36 is fixedly connected to one end of each of the two side plates 35. This achieves the effect of the pull frame 36 being fixed to the side plate 35.

[0040] Working principle: When a water sample needs to be filtered, the operator first moves the outer cylinder 205 so that it is aligned with the sampling tube 5. By pushing the outer cylinder 205 towards the sampling tube 5, the magnetic ring 203 on the mounting ring 204 and the adsorption ring 202 on the mounting ring 204 are magnetically attracted, achieving precise positioning of the outer cylinder 205. This positioning can be fixed by the position of the through plate 206, ensuring that the filter screen 207 accurately covers the sampling port of the sampling tube 5. Then, the micro water pump 4 is started, and the water sample to be tested passes through... After filtration by the filter screen 207, the sample enters the sampling tube 5. During this process, the mating structure of the assembly ring 209 and the sealing ring 210 can effectively prevent the water sample from entering the inner cavity of the outer cylinder 205. Through the filtration device 2, the problem of traditional portable water quality testing devices that can quickly sample using an open straight cylinder structure for the sampling port, which does not have any filtering components for impurities in the water sample, is solved. Due to the lack of a filter barrier at the sampling port, impurities will directly enter the inner cavity of the sampling tube 5 with the water sample, interfering with the subsequent testing results.

[0041] When the sampling and testing instrument 1 needs to be retrieved using the lifting device 3, the operator first pulls the pull frame 36. The pull frame 36, under force, causes the side plate 35 to rotate around the rotating ring 34. The rotating ring 34 simultaneously causes the rubber ring 33 to rotate on the round rod 32. After the pull frame 36 rotates to a certain angle around the round rod 32, it can be gripped, thus completing the retrieval of the sampling and testing instrument 1. The lifting device 3 solves the problem that traditional portable water quality testing devices that can quickly sample mostly use bare units or rely on storage bags for carrying. When the device is not in use, the outer shell of the device must be held directly, and the lack of a dedicated moving auxiliary structure increases the risk of the device being dropped and damaged.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
