A highly secure sealed sampler

Abstract

This utility model relates to the field of sampler technology, specifically a highly safe sealed sampler, including a sampler body. The sampler body has a sampling area at its front end, and a sampling tube connected to the sampler body is located on the sampling area. A horizontal plate is located on the inner wall of the sampling area below the sampling tube. Two opposing closing plates are slidably mounted on the horizontal plate to seal the sampling tube opening. A fixing post is located on the bottom end face of the sampling area on one side of the sampling tube, and an internal groove is formed within the fixing post. A drive rod is located within the internal groove. This utility model allows for the simultaneous completion of two operations: removing the sampling bottle and sealing the sampling tube opening, by rotating a drive handwheel. The two closing plates close below the end face of the sampling tube, thereby sealing the tube opening and preventing any residual liquid that may drip from inside the sampling tube. This effectively isolates the residual liquid and prevents it from dripping directly onto the operator's hands, improving the safety of the sampling process.

Description

Technical Field

[0001] This utility model relates to the field of sampler technology, specifically a highly secure sealed sampler. Background Technology

[0002] The closed sampler is suitable for leak-free sampling of various media under process conditions in pipelines of petroleum and chemical plants, especially hazardous medium and low-pressure gaseous and liquid media such as toxic, flammable, and explosive media. It provides highly authentic and accurate samples with no residual liquid or gas emissions, effectively preventing harm from toxic and harmful media while avoiding environmental pollution and potential hazards during sampling of flammable and explosive media.

[0003] After sampling, existing closed samplers often leave a certain amount of sample liquid residue inside or on the end face of the sampling tube. When operators disassemble the sampling bottle, this residual liquid may drip due to gravity or vibration, posing a risk of direct contact with the operator's skin (especially hands). If the collected medium is toxic, corrosive, or other hazardous chemicals, it will directly harm the safety and health of the operator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly secure, sealed sampler.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highly secure sealed sampler includes a sampler body. A sampling area is located at the front end of the sampler body. A sampling tube connected to the sampler body is located on the sampling area. A horizontal plate is located on the inner wall of the sampling area below the sampling tube. Two opposing closing plates for sealing the sampling tube opening are slidably mounted on the horizontal plate. A fixing post is located on the bottom end face of the sampling area on one side of the sampling tube. An internal groove is formed within the fixing post. A driving rod is located within the internal groove. The driving rod within the internal groove has symmetrical positive and negative threads. Both the positive and negative threads are threaded with driving plates. A connecting plate extending to the outside of the fixing post is provided on the driving plate. One connecting plate has an annular plate sleeved on the outside of the sampling tube, and the other connecting plate has a bottom support plate located directly below the sampling tube.

[0007] As a further embodiment of this utility model, the annular plate is provided with two opposing first connecting seats, and the two closed plates are respectively provided with second connecting seats corresponding to the first connecting seats. A connecting rod is rotatably connected between the corresponding first connecting seats and the second connecting seats.

[0008] As a further embodiment of this utility model, a guide plate is provided on the side of the closing plate near the horizontal plate, and a guide groove is provided on the horizontal plate to allow the guide plate to move.

[0009] As a further embodiment of this utility model, one end of the drive rod is rotatably connected to the built-in groove, and the other end of the drive rod extends to the outside of the fixed column and is provided with a drive handwheel.

[0010] As a further embodiment of this utility model, the fixed column is provided with a displacement groove that allows the two connecting plates to move, and the displacement groove is connected to the built-in groove.

[0011] As a further embodiment of this utility model, the top end face of the base plate is provided with a receiving groove for placing the sampling bottle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows for the simultaneous removal of the sampling bottle and sealing of the sampling tube opening by rotating a drive handwheel.

[0022] Example

[0023] refer to Figures 1-5 A highly secure sealed sampler includes a sampler body 1. The sampler body 1 has a sampling area at its front end, and a sampling tube 101 connected to the sampler body 1 is provided on the sampling area. A horizontal plate 102 is provided on the inner wall of the sampling area below the sampling tube 101. Two opposing closing plates 103 for sealing the sampling tube opening are slidably mounted on the horizontal plate 102. A fixing post 104 is provided on the bottom end face of the sampling area on one side of the sampling tube 101. An internal groove 105 is formed in the fixing post 104, and a driving rod 106 is provided in the internal groove 105. Symmetrical positive screws are provided on the driving rod 106 located in the internal groove 105. Drive plates 109 are threadedly connected to both the positive thread 107 and the negative thread 108. The drive plates 109 are provided with connecting plates 110 extending to the outside of the fixed post 104. One connecting plate 110 is provided with an annular plate 111 that fits onto the outside of the sampling tube 101. The other connecting plate 110 is provided with a bottom support plate 112 located directly below the sampling tube 101. The top end face of the bottom support plate 112 is provided with a receiving groove 120 for placing the sampling bottle 2, thereby ensuring that the bottle mouth of the sampling bottle 2 is precisely aligned with the tube mouth of the sampling tube 101 and ensuring the stability of the sampling bottle 2 during the up and down movement of the bottom support plate 112.

[0024] The annular plate 111 is provided with two opposing first connecting seats 113, and the two closed plates 103 are respectively provided with second connecting seats 114 corresponding to the first connecting seats 113. A connecting rod 115 is rotatably connected between the corresponding first connecting seats 113 and second connecting seats 114. When the annular plate 111 moves up or down, the connecting rod 115 drives the two closed plates 103 to slide towards the middle or to both sides, thereby closing or opening the sampling tube 101 opening.

[0025] The closing plate 103 is provided with a guide plate 116 on the side near the horizontal plate 102. The horizontal plate 102 is provided with a guide groove 117 that allows the guide plate 116 to move. The arrangement of the guide plate 116 and the guide groove 117 not only ensures that the closing plate 103 is always connected to the horizontal plate 102, but also guides the displacement direction of the closing plate 103.

[0026] One end of the drive rod 106 is rotatably connected to the built-in groove 105, and the other end of the drive rod 106 extends to the outside of the fixed column 104 and is provided with a drive handwheel 118. The drive handwheel 118 facilitates the operator to drive the drive rod 106 to move the drive plate 109.

[0027] The fixed column 104 is provided with a displacement groove 119 that allows the two connecting plates 110 to move. The displacement groove 119 is connected to the built-in groove 105. The displacement groove 119 can limit the displacement of the connecting plate 110.

[0028] It should be added that after each sampling or after each batch of sampling is completed, the operator must wear personal protective equipment in strict accordance with the requirements after disassembling the sampling bottle 2. Then, use compatible absorbent materials (such as lint-free cloths or absorbent cotton) to manually wipe and clean all surfaces that may come into contact with the sample, such as the closing plate 103 and the bottom plate 112. The used cleaning materials must be treated as hazardous waste and placed in the designated sealed container.

[0029] The working principle of this utility model:

[0030] refer to Figures 1-2During sampling, the operator first places the sampling bottle 2 into the receiving slot 120. Then, by rotating the drive handwheel 118, the drive rod 106 is rotated, which in turn drives the two drive plates 109 to move towards each other. These two drive plates 109 drive the annular plate 111 to move downward and the bottom support plate 112 to move upward, respectively, through the connecting plate 110. When the annular plate 111 moves downward, the connecting rod 115 pushes the two closing plates 103 to slide along the horizontal plate 102 to both sides, thereby opening the closing plate 103 located below the end face of the sampling tube 101, so that the opening of the sampling tube 101 is fully exposed. At the same time, the bottom support plate 112 moves upward, so that the opening of the sampling bottle 2 is connected with the opening of the sampling tube 101, and normal sampling operation can be carried out.

[0031] refer to Figures 3-4 After sampling is completed, the operator rotates the drive handwheel 118 in the opposite direction, causing the drive rod 106 to drive the two drive plates 109 to move in opposite directions. These two drive plates 109 drive the annular plate 111 to move upward and the bottom support plate 112 to move downward respectively through the connecting plate 110. When the annular plate 111 moves upward, the connecting rod 115 pulls the two closing plates 103 to slide along the horizontal plate 102 towards the middle, so that the closing plates 103 close below the end face of the sampling tube 101 to block any residual liquid that may drip from inside the sampling tube 101. At the same time, the bottom support plate 112 smoothly supports the sampling bottle 2 and descends synchronously. At this time, the opening of the sampling tube 101 has been sealed by the closing plate 103, and the residual liquid is effectively isolated. The operator can safely remove the sampling bottle 2 from the receiving groove 120 of the bottom support plate 112.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
