Generally, a lifting mechanism is used to avoid personnel directly contacting the high-temperature media and improve operational safety. However, when existing lifting mechanisms are used in conjunction with sampling containers to sample the media, the sampling container is prone to tipping over due to the buoyancy of the media and other external forces, affecting the normal sampling of the sampling container. At the same time, media splashing affects the safety of sampling.
[0005] To address the aforementioned problems, this invention proposes a sampling device suitable for liquid media that can prevent the sampling container from tipping over during the sampling process. Utility Model Content

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0028] Please see Figure 1-2 This utility model provides a technical solution: a sampling device suitable for liquid media includes a connector 100 and a sampling container 200. The sampling device suitable for liquid media is provided with a sampling direction and a flipping direction that are perpendicular to each other. The connector 100 and the sampling container 200 are arranged sequentially along the sampling direction. The two ends of the sampling container 200 in the length direction are a connecting end a and a placement end b, respectively. The size of the sampling container 200 in the sampling direction is much larger than its size in the flipping direction.
[0029] The connector 100 is provided with a first annular connecting structure, and the connecting end a of the sampling container 200 is provided with a second annular connecting structure. The first connecting structure and the second connecting structure are fastened and abutted against each other in the sampling direction, and the first connecting structure and the second connecting structure are mutually constrained in the flipping direction. The first connecting structure and the second connecting structure are detachably connected.
[0030] In use, the connector 100 places the sampling container 200 in the sampling area along the sampling direction to complete the sampling. A first connecting structure and a second connecting structure are provided between the connector 100 and the sampling container 200. The relative positions of the first connecting structure and the second connecting structure in the sampling direction and the flipping direction are constrained when they are connected. The dimensions of the sampling container 200 in the flipping direction and the sampling direction are further limited to prevent the sampling container 200 from flipping during the sampling process.
[0031] Furthermore, the connector 100 is provided with a connection hole 101 along the flipping direction, and the inner wall of the connection hole 101 forms the first connection structure.
[0032] A slot 201 is provided in the middle of the connecting end a along the sampling direction. A limiting member 202 is arranged in the flipping direction on the side of the slot 201 near the opening. The limiting member 202 and the inner wall of the slot 201 form the second connecting structure. The end of the connector 100 is adapted to be inserted into the inner side of the slot 201 along the sampling direction. The limiting member 202 is adapted to pass through the connecting hole 101. The bottom surface of the slot 201 and the end surface of the connector 100 abut against each other. The bottom surface of the slot 201 and the end surface of the connector 100 are both arranged along the flipping direction.
[0033] Furthermore, the limiting member 202 and the connecting member 100 are detachably connected. Preferably, the limiting member 202 is a pin, and the inner wall of the slot 201 is provided with a pin hole corresponding to the limiting member 202.
[0034] Furthermore, the connector 100 includes a first clamp 102 and a second clamp 103 arranged opposite to each other in the flipping direction. A connecting groove 1011 is provided on the opposite side of both the first clamp 102 and the second clamp 103. The first clamp 102 and the second clamp 103 are configured to move closer to and further away from each other in the flipping direction. The connector 100 has at least two working states: a connected state and a disengaged state. When the connector 100 is in the connected state, the first clamp 102 and the second clamp 103 move closer to each other in the flipping direction, with their opposite sides abutting. The connecting groove 1011 on the first clamp 102 and the connecting groove 1011 on the second clamp 103 forms the connecting hole 101. When the connector 100 is in the disengaged state, the first clamp 102 and the second clamp 103 move further away from each other in the flipping direction, and a gap is formed between the first clamp 102 and the second clamp 103 for the second connecting structure to enter and exit. In use, the limiting member 202 and the connecting member 100 can be disassembled and / or the working state of the connecting member 100 can be switched, thus separating the connecting member 100 and the sampling container 200.
[0035] See Figure 3 and 4 Furthermore, the sampling container 200 has a smooth external cylindrical structure, and the center of the insertion end b and the center of the connection end a of the sampling container 200 both extend outward to form an arc surface. With the above limitations, the sampling container 200 has the following advantages in use: 1. Easy to obtain: After the sampling container 200 obtains the liquid medium sample, the liquid medium is within the medium cavity 203 and is not easily spilled. Moreover, the sampling container 200 is a long, cylindrical shape, which has a low center of gravity during sampling operations, making it less prone to tipping over; 2. Easy to collect: During operation, the sampler can easily grasp the sampling container 200 with this structural form.
[0036] Furthermore, the sampling container 200 is provided with a medium cavity 203, and the sampling container 200 is provided with a liquid inlet 204 that connects the inside and outside of the medium cavity 203. The liquid inlet 204 is arranged close to the connection end a. Furthermore, there are multiple liquid inlets 204, which are arranged at intervals along the circumference of the sampling container 200 to maximize the amount of medium sample that the medium cavity 203 can draw. Preferably, there are four liquid inlets 204, which are arranged at equal intervals along the circumference of the sampling container 200. After the sampling operation is completed, the sampler can use a special seal to seal the four liquid inlets 204 to prevent the liquid sample from flowing out and to prevent external impurities from entering the medium cavity 203 through the liquid inlets 204 and contaminating the medium sample. The sampler will affix labels to the sampling container 200 with relevant information such as sampling time, sampling content, and sampler, similar to blood tests in a hospital. The sampling container 200, which has been used to collect the liquid medium sample, will be placed vertically in the isolation chamber for neat arrangement and storage.
[0037] Furthermore, the sampling container 200 includes a body portion 205 and a head portion 206 connected sequentially between the insertion end b and the connection end a. The body portion 205 is provided with a medium cavity 203. The side of the body portion 205 facing the head portion 206 is provided with an interface 207 that communicates with the inside and outside of the medium cavity 203. The head portion 206 opens and closes to the interface 207. The liquid inlet 204 is arranged close to the interface 207. Preferably, the body 205 has a reserved connection area between the interface 207 and the liquid inlet 204. An internal thread is provided inside the connection area, and an external thread is provided on the outside of the head 206 facing the body 205. The internal thread and the external thread are sealed together. In use, the sampling container 200 can be assembled by rotating the internal thread and the external thread. Specifically, when installing the head 206, align the external thread of the head 206 with the internal thread of the body 205, rotate it manually first, and after the head 206 is screwed into two or three threads of the body 205, insert a flathead screwdriver into the slot 201 and tighten the head 206 by rotating the screwdriver.
[0038] Furthermore, the sampling container 200 is made of SUS304 stainless steel, and the outer surface of the sampling container 200 is plated with a layer of nickel to improve the corrosion resistance of the sampling container 200.
[0039] Furthermore, a lifting member 300 is provided on the side of the connector 100 away from the sampling container 200. The lifting member 300 is configured to control the movement of the connector 100 and the sampling container 200 along the sampling direction. Preferably, the lifting member 300 is a steel wire.

[0043] S2: Align the external thread of the head 206 of the sampling container 200 with the internal thread of the body 205. First, rotate manually, then use a flathead screwdriver to insert into the card slot 201 and rotate until the external thread of the head 206 of the sampling container 200 is fully screwed into the internal thread of the body 205 and tightened in place to ensure that there is no loosening.
[0044] S3: Insert the pin into the head 206 of the sampling container 200, install a nut at each end of the pin, and tighten it;
[0045] S4: The first clamp 102 and the second clamp 103 of the connector 100 can be closed, and a first connection structure is formed between the first clamp 102 and the second clamp 103 after being closed. The first connection structure cooperates with the second connection structure to suspend the sampling container 200.
[0046] S5: Suspend connector 100 with wire rope, lower the wire rope, and then place sampling container 200 into the dissolved liquid medium for sampling.
