[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] First embodiment

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a chemical detection sampler provided by the present invention; Figure 2 for Figure 1 A schematic cross-sectional view of the sampling cylinder shown; Figure 3 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 1 The bottom view of the sampling cylinder is shown. The chemical detection sampler comprises: a sampling cylinder 2;

[0024] A piston 5 is slidably connected to the inside of the sampling cylinder 2, and a sampling port 6 is provided at one end of the sampling cylinder 2. The inner wall of the sampling port 6 is provided with a one-way interception piece 7, and the one-way interception piece 7 is made of flexible material and has a triangular structure. The one-way interception piece 7 is arranged in a circular ring shape about the inner wall of the sampling port 6. A first sampling component 3 and a second sampling component 4 are respectively provided on both sides of the sampling cylinder 2. The first sampling component 3 includes a first sampling tube 32 connected to one side of the sampling cylinder 2. The first sampling tube 32 of this device is used for discharging sample liquid. The inner wall of the first sampling tube 32 is provided with an interception net 35. The second sampling component 4 includes a second sampling tube 42 connected to the other side of the sampling cylinder 2. The second sampling tube 42 of this device is used for discharging solids.

[0025] An opening is provided at the top of the first sample outlet tube 32, and a first sealing plug-in plate 31 is inserted into the opening. The first sealing plug-in plate 31 is made of rubber. This structure can seal the first sample outlet tube 32 through the first sealing plug-in plate 31. The first sealing plug-in plate 31 is located on one side of the interception net 35. The interception net 35 of this structure can filter the liquid and solid in the sample to achieve automatic separation of solid and liquid. A first connecting block 33 is fixedly connected to one side of the first sealing plug-in plate 31, and a first connecting spring 34 is fixedly connected to the bottom of the first connecting block 33. One end of the first connecting spring 34 is fixedly connected to the top of the first sample outlet tube 32.

[0026] An opening is provided at the top of the second sample outlet tube 42, and a second sealing plug plate 41 is inserted into the opening. The second sealing plug plate 41 and the second sample outlet tube 42 are slidably connected. A second connecting block 43 is fixedly connected to one side of the second sealing plug plate 41, and a second connecting spring 44 is fixedly connected to the bottom of the second connecting block 43. One end of the second connecting spring 44 is fixedly connected to the top of the second sample outlet tube 42.

[0027] A pull rod 1 is inserted into the other end of the sampling cylinder 2, and one end of the pull rod 1 is connected to the piston 5. This structure allows the pull rod 1 to drive the piston 5 to move upward by pulling the pull rod 1, so that the sample enters from the sampling port 6 of the sampling cylinder 2.

[0028] The working principle of the chemical detection sampler provided by the utility model is as follows:

[0029] When using the chemical detection sampler, first align the sampling port 6 of the sampling cylinder 2 with the sample to be taken, then pull the push rod 1, which drives the piston 5 to move inside the sampling cylinder 2. The piston 5 generates suction during the movement, which causes the one-way interception piece 7 to bend inward to open the sampling port 6. At this time, the sample enters the interior of the sampling cylinder 2. Then, if the sample needs to be released, pull the first sealing plug plate 31 upward, and the liquid in the sample passes through the interception net 35 and is discharged from the first sample outlet tube 32, while the solid in the sample is intercepted. Then pull the second sealing plug plate 41 upward, the second sealing plug plate 41 opens, and then tilt the sampling cylinder 2, and the solid sample is discharged from the second sample outlet tube 42.

[0030] Compared with related technologies, the chemical detection sampler provided by the utility model has the following beneficial effects:

[0031] By connecting the first sample outlet tube 32 and the second sample outlet tube 42 on both sides of the sampling cylinder 2 respectively, and providing a sampling port 6 at the bottom of the sampling cylinder 2, the sample enters the sampling cylinder 2 from the sampling port 6. When the first sample outlet 32 ​​is opened, the sample liquid is filtered and discharged through the interception net 35, and the solid in the sample is discharged from the second sample outlet tube 42, which can achieve solid-liquid separation in the sample, thereby improving the sampling efficiency and the chemical detection efficiency; by providing a second connecting spring 44 and a first connecting spring 34 on one side of the second sealing plug plate 41 and the first sealing plug plate 31 respectively to connect with the second sample outlet tube 42 and the first sample outlet tube 32, the second sealing plug plate 41 and the first sealing plug plate 31 can be tightly fitted with the second sample outlet tube 42 and the first sample outlet tube 32 respectively under the limitation of the tension of the second connecting spring 44 and the first connecting spring 34, thereby ensuring the sealing effect of the second sample outlet tube 42 and the first sample outlet tube 32.

[0032] Second embodiment

[0033] Please refer to Figure 5 Based on the chemical detection sampler provided in the first embodiment of the present application, the second embodiment of the present application provides another chemical detection sampler. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0034] Specifically, the difference of the chemical detection sampler provided in the second embodiment of the present application is that the interior of the first sample outlet tube 32 is rotatably connected to a rotating ring 8, the intercepting net 35 is installed on the rotating ring 8, the top of the first sample outlet tube 32 is rotatably connected to a rotating pin 9, the bottom of the rotating pin 9 passes through the first sample outlet tube 32 and is fixedly connected to the rotating ring 8, the left side of the rotating pin 9 is fixedly connected to the first positioning sleeve 10, and the right side of the rotating pin 9 is fixedly connected to the second positioning sleeve 11.

[0035] The top of the first sample outlet tube 32 is slidably connected to a sliding block 12, the left side of the sliding block 12 is fixedly connected to a positioning block 13, the top of the first sample outlet tube 32 is fixedly connected to a fixed block 14, a third connecting spring 15 is provided between the sliding block 12 and the fixed block 14, the top of the fixed block 14 is slidably connected to a shaft rod 16, one end of the shaft rod 16 is fixed to the sliding block 12.

[0036] Compared with related technologies, the chemical detection sampler provided by the utility model has the following beneficial effects:

[0037] When the interception net 35 is performing solid-liquid separation, the solid will be intercepted on the left side by the interception net 35, which will inevitably cause blockage after long-term use. At this time, the shaft 16 can be manually pulled to move the sliding block 12 to the right, thereby separating the positioning block 13 from the second positioning sleeve 11, and then rotating the rotating pin 9 to rotate the rotating circle 8, thereby rotating the interception net 35 half a circle. At this time, after releasing the shaft 16, the third connecting spring 15 rebounds, indirectly causing the positioning block 13 to be inserted into the first positioning sleeve 10 to fix the rotating pin 9, thereby indirectly fixing the interception net 35. After the left and right sides of the interception net 35 are reversed, the blocked side can be flushed with water and unblocked, which facilitates the cleaning of the interception net 35.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
