Description

Technical Field

[0001] The invention relates to a detection sampling device, in particular to a sampler that can be used in complex environments. Background Art

[0002] A sampler is a sampling device used in various fields such as the chemical industry and manufacturing industry that require sampling, testing and analysis. Currently, most commonly used samplers are rod-shaped in design, which can be moved downward to take samples and then reset. They are all used for sampling activities in normal spaces. However, for some special scenarios, such as "concave"-shaped equipment and other large-volume special-shaped equipment, due to the setting of the feeding device at the feed port at one end, insufficient equipment space and the impact of continuous feeding, the sampler cannot be directly inserted into the feed port for sampling. The sampler must be inserted from the other port, but the sampler cannot obtain the material sample from the feed port that is relatively far away from the other port. In this case, the only way is to change the structure of the equipment itself to adapt to the sampler, or to stop the operation for sampling and inspection, which increases costs and has an adverse effect on normal production. Summary of the invention

[0003] The technical problem to be solved by the present invention is that most existing samplers are rod-shaped in design and are not suitable for sampling in special environments such as irregular and large-volume equipment. The present invention provides a sampler that can be used in complex environments to solve the above problem. It is particularly suitable for environments with special requirements for sampling ports and sampling positions. For example, for "concave" type equipment, it is necessary to meet the requirement of extending the sampler from one inlet to obtain sampling of materials at the other inlet.

[0004] The present invention is achieved through the following technical solutions:

[0005] A sampling assembly that can be used in complex environments comprises a fixed rod and a sampling rod, wherein one end of the sampling rod or a portion near the end thereof is used to mount a sampling container; the sampling rod is arranged on the fixed rod through a fixed part, and the fixed part is driven to rotate through a transmission part, thereby driving the sampling rod to rotate around the fixed part, so that the angle between the fixed rod and the sampling rod varies from 0° to 360°.

[0006] The present invention provides a sampling assembly, which is composed of a fixed rod and a sampling rod as the main structure, and the sampling rod and the fixed rod can rotate relative to each other through a fixing member: when not in operation, the fixed rod and the sampling rod are placed overlapping each other to save space, that is, the angle between the fixed rod and the sampling rod is 0°. When work is required, firstly, a fixing member of suitable height is selected on the fixed rod, the sampling rod is installed on the fixing member by a detachable connection method such as a screw, and the sampling container is fixed to the end of the sampling rod. Then, the fixed rod and the sampling rod are kept in an overlapping position, and the sampler is extended into the tank of the equipment. Then, the fixed member is driven to rotate by controlling the transmission member, and the fixed member drives the sampling rod to rotate around the fixed member as the center, such as rotating to a position where the sampling rod and the fixed rod are at an angle of 90°, that is, the sampling rod and the fixed rod are perpendicular to each other, and the sampling activity is performed through the sampling container. After sampling is completed, the fixed part is driven to reset by controlling the transmission part, and the sampling rod is synchronously driven to rotate to a position parallel to the fixed rod, that is, the angle between the sampling rod and the fixed rod is 0°, and the sampling is restored to the previous state, and the sampler is taken out of the equipment tank, and the sampling is completed. It is particularly suitable for environments with special requirements for sampling ports and sampling positions. For example, for "concave" type equipment, it meets the sampling requirements of extending the sampler from one end entrance to obtain the material at the other end entrance. Using the sampling assembly provided by the present invention, there is no need to change the structure of the equipment itself to adapt to the sampler, and there is no need to stop sampling and inspection, which is conducive to saving costs and ensuring continuous normal operation of production. In addition, the sampling rod can change the angle of 0° to 360° relative to the fixed rod. Therefore, with the connection point of the sampling rod and the fixed rod as the center, it is convenient to quickly sample all samples within the radius range of the length of the sampling rod, and it is more flexible.

[0007] Furthermore, it comprises a plurality of fixing members, and the plurality of fixing members are distributed axially along the fixing rod.

[0008] By arranging multiple fixings along the axial direction on the fixing rod, it is convenient for the staff to select the appropriate fixing to connect with the sampling rod according to the actual sampling height. If a sample with a smaller depth in the equipment tank needs to be obtained, the fixing near the top of the fixing rod is selected to connect with the sampling rod; if a sample with a larger depth in the equipment tank needs to be obtained, the fixing near the bottom of the fixing rod is selected to connect with the sampling rod. The fixing rod and the sampling rod can be connected by an existing detachable connection structure such as a screw.

[0009] Furthermore, each fixing member is independently controlled by a corresponding group of transmission members to achieve rotational motion, or all the fixing members are simultaneously controlled by a group of transmission members to achieve rotational motion.

[0010] According to the detection requirements and the overall size of the sampler, several sets of independently controlled rotational fixings may be involved, or in order to simplify the structure and miniaturize and simplify the sampler, a set of transmission parts may be used to simultaneously control the rotational movement of all fixings.

[0011] Furthermore, the transmission mechanism adopted by the transmission member includes a screw transmission mechanism, a conveyor belt mechanism or a gear transmission mechanism.

[0012] The transmission mechanism that can be used by the transmission member includes but is not limited to some existing screw transmission mechanisms, conveyor belt mechanisms or gear transmission mechanisms.

[0013] Furthermore, the fixing rod adopts a hollow tube structure, and the transmission member is placed in the hollow chamber of the tube structure.

[0014] The tube is used as a fixing rod, so that the transmission part can be directly installed in the tube, which is beneficial to saving space and realizing miniaturization of the sampler.

[0015] Furthermore, the gear transmission mechanism includes a transmission chain, the transmission direction of the transmission chain is distributed along the axial direction of the fixed rod, and the two ends of the transmission chain are respectively fixed to the two axial ends of the fixed rod by gears; the fixed part adopts a transmission shaft, the axial direction of the transmission shaft is perpendicular to the axial direction of the fixed rod, the transmission shaft passes through the hollow chamber of the tube structure, the two ends of the transmission shaft are rotatably connected to the side wall of the tube structure, and at least one end passes through the side wall of the tube structure and extends out of the hollow chamber for connecting the sampling rod; a transmission gear adapted to the transmission chain is rigidly connected to the transmission shaft located in the hollow chamber of the tube structure.

[0016] The present invention preferably uses a transmission chain as a transmission member, which has a simple structure and low cost.

[0017] Furthermore, the two ends of the transmission chain are respectively fixed to the axial ends of the fixed rod through a driving gear and a driven gear. A driving shaft is provided on the driving gear. One end of the driving shaft is rigidly connected to the driving gear, and the other end is used to connect to a motor or a manual operating lever.

[0018] The transmission member of the present invention can be controlled manually or automatically by a motor.

[0019] A sampler that can be used in complex environments comprises a sampling container and the above-mentioned sampling assembly that can be used in complex environments; the sampling container is rotatably connected to the sampling rod, so that the angle between the axis of the sampling container and the axis of the sampling rod varies from 0° to 360°, and the opening of the sampling container is always facing upward.

[0020] The working principle of the sampler provided by the present invention is as follows: when not in operation, the three components of the fixed rod, the sampling rod and the sampling container are placed overlapping each other to save space. When it is necessary to work, first select a fixing member of suitable height on the fixed rod, and install the sampling rod on the fixing member by a detachable connection method such as a screw. Then keep the three components of the fixed rod, the sampling rod and the sampling container overlapping each other, at this time, the axial direction of the fixed rod, the axial direction of the sampling rod and the axial direction of the sampling container are perpendicular to each other, and extend the sampler into the equipment tank. Then, by controlling the transmission member to drive the fixed member to rotate, the fixed member drives the sampling rod to rotate around the fixed member as the center, such as rotating to the position where the sampling rod and the fixed rod are at an angle of 90°, that is, the sampling rod and the fixed rod are perpendicular, and the sampling activity is performed through the sampling container. After the sampling is completed, the fixed member is reset by controlling the transmission member, and the sampling rod is synchronously driven to rotate to a position parallel to the fixed rod, that is, the angle between the sampling rod and the fixed rod is 0°, and the previous state is restored, and the sampler is taken out of the equipment tank, and the sampling is completed. During the entire sampling process, the sampling container always remains open upward due to its own gravity.

[0021] Furthermore, the sampling container is connected to the sampling rod through a rotating connector, and the connection point between the rotating connector and the sampling container is one or more; and the relative rotation center point between the sampling container and the sampling rod is located at the connection point between the rotating connector and the sampling rod, or at the connection point between the rotating connector and the sampling container.

[0022] The rotatable connection part between the sampling container and the sampling rod of the present invention can adopt various structures and forms, as long as the included angle between the axis of the sampling container and the axis of the sampling rod varies from 0° to 360° and the opening of the sampling container is always facing upward.

[0023] Furthermore, the bottom of the sampling container is in a conical structure. The sampling container with a conical structure is conducive to the concentration of the overall gravity of the sampling container, ensuring that the sampling container always maintains an upward opening due to its own gravity during the entire sampling process.

[0024] The present invention has the following advantages and beneficial effects:

[0025] The present invention provides a sampling assembly, which is composed of a fixed rod and a sampling rod as the main structure, and the sampling rod and the fixed rod can rotate relative to each other through a fixing part. It is particularly suitable for environments with special requirements for sampling ports and sampling positions, such as for "concave" type equipment, to meet the sampling requirements of extending the sampler from one end entrance to obtain the material at the other end entrance. By adopting the sampling assembly provided by the present invention, there is no need to change the structure of the equipment itself to adapt to the sampler, and there is no need to stop the operation for sampling and inspection, which is conducive to saving costs and ensuring the continuous normal operation of production. In addition, the sampling rod can change the angle of 0° to 360° relative to the fixed rod. Therefore, with the connection point of the sampling rod and the fixed rod as the center, it is convenient to quickly sample all samples within the length radius of the sampling rod, and it is more flexible.

The installation position of the sampling container 3 on the sampling rod 2 is not limited, and it is preferably installed at the end of the sampling rod 2, which is conducive to ensuring that the sampling container 3 can reach the maximum sampling range. Multiple connection points are sequentially arranged along the axial direction on the sampling rod 2 for installing the sampling container 3. According to the sampling radius range, the connection points at the corresponding length position are selected to connect with the sampling container 3. The sampling rod 2 is set on the fixed rod 1 through a fixing member 4, and the fixing member 4 is driven to rotate through a transmission member 5, thereby driving the sampling rod 2 to rotate around the fixing member 4, so that the angle between the fixed rod 1 and the sampling rod 2 changes from 0° to 360°. The transmission member 5 can adopt a transmission mechanism such as a spiral transmission mechanism, a conveyor belt mechanism or a gear transmission mechanism.

Each fixing member 4 is independently controlled by a corresponding group of transmission members 5 to realize rotational motion, or all fixing members 4 are simultaneously controlled by a group of transmission members 5 to realize rotational motion. The transmission mechanism used by the transmission member 5 includes a spiral transmission mechanism, a conveyor belt mechanism or a gear transmission mechanism; the fixing rod 1 adopts a hollow tube structure, and the transmission member 5 is placed in the hollow chamber of the tube structure.

The fixed member 4 adopts a transmission shaft 41, and the axial direction of the transmission shaft 41 is arranged perpendicular to the axial direction of the fixed tube. The transmission shaft 41 penetrates the interior of the fixed tube in the radial direction, and the two ends of the transmission shaft 41 are rotatably connected to the opposite side walls of the fixed tube, and at least one end penetrates the side wall of the fixed tube and extends out of the hollow cavity for connecting the sampling rod 2. All the transmission shafts 41 and the rotating shafts 51 are meshed and transmitted with each other through a group of spiral bevel gears 53. The rotating shaft 51 is driven to rotate by an external force (such as a motor), and the transmission shaft 41 is driven to rotate by the vertical transmission of the spiral bevel gears 53. The transmission shaft 41 rotates and moves, and the rotation of the transmission shaft 41 drives the sampling rod 2 to rotate synchronously.

[0044] Based on the further improvement of embodiment 2, the transmission member 5 adopts a gear transmission mechanism, such as Figure 5 As shown, the gear transmission mechanism includes a transmission chain 51, which is arranged in a tubular fixed rod 1 (referred to as the fixed tube), and the transmission direction of the transmission chain 51 is distributed along the axial direction of the fixed tube, and the two ends of the transmission chain 51 are respectively fixed to the two axial ends of the fixed tube through gears; the fixed member 4 adopts a transmission shaft 41, and the axial direction of the transmission shaft 41 is arranged perpendicular to the axial direction of the fixed tube. The transmission shaft 41 passes through the hollow chamber of the fixed tube, and the two ends of the transmission shaft 41 are rotatably connected to the opposite side walls of the fixed tube, and at least one end passes through the side wall of the fixed tube and extends out of the hollow chamber for connecting the sampling rod 2. The transmission shaft 41 located in the fixed tube is rigidly connected with a transmission gear adapted to the transmission chain. The two ends of the transmission chain 51 are respectively fixed to the two axial ends of the fixed tube through a driving gear 52 and a driven gear 53. The driving gear 52 is provided with a driving shaft 54, one end of the driving shaft 54 ​​is rigidly connected to the driving gear 52, and the other end is used to connect the motor or the manual operating rod.

[0045] Example 4

[0046] This embodiment provides a sampler that can be used in complex environments, including a sampling container 3 and a sampling assembly provided in Embodiment 3. The sampling container 3 is rotatably connected to the sampling rod 2, so that the included angle between the axis of the sampling container 3 and the axis of the sampling rod 2 varies from 0° to 360°, and the opening of the sampling container 3 is always facing upward.

[0047] Example 5

[0048] Based on the further improvement of Example 4, the sampling container 3 adopts a cylindrical structure with an open axial top and a closed axial bottom, and the bottom of the cylinder is a conical structure. Figure 7As shown, the sampling container 3 is connected to the sampling rod 2 through a rotating connector 6. The rotating connector 6 includes a connecting rod and a hinge. One axial end of the connecting rod is fixedly connected to the end of the sampling rod 2, and the connecting rod and the sampling rod 2 are perpendicular to each other. The other axial end of the connecting rod is rotatably connected to the side wall of the sampling container 3 through an existing hinge. The hinge here includes but is not limited to the existing double-ear plate hinge structure, or a hanging ring, or a bearing rotation, or a universal hinge. Similarly, one end of the connecting rod can also be connected to the sampling rod 2 through a hinge, and the other end can be fixedly connected to the side wall of the sampling container 3. The connection point between the connecting rod and the sampling container 3 is located above the center of gravity of the sampling container 3.

[0049] Example 6

[0050] Based on the further improvement of Example 4, the sampling container 3 adopts a cylindrical structure with an open axial top and a closed axial bottom, and the bottom of the cylinder is a conical structure. Figure 8 As shown, the sampling container 3 is connected to the sampling rod 2 via a rotating connector 6. The rotating connector 6 includes a C-shaped connector and a hinge.

The three free ends of the tripod are fixedly connected to the side wall of the sampling container 3, and the top of the tripod is rotatably connected to the end of the sampling rod 2 through the hinge.

[0052] The working principle of a sampler that can be used in a complex environment provided in Example 4 is as follows:

[0053] (1) When not in operation, the fixing rod, the sampling rod and the sampling container are placed overlapping each other to save space.

[0054] (2) When work is required, first select a fixing of suitable height on the fixing rod, and install the sampling rod on the fixing rod by means of detachable connection such as screws. Then keep the fixing rod, sampling rod and sampling container in overlapping positions. At this time, the axes of the fixing rod, sampling rod and sampling container are perpendicular to each other, and extend the sampler into the tank of the equipment. Then, by controlling the transmission part to drive the fixing part to rotate, the fixing part drives the sampling rod to rotate around the fixing part as the center, such as rotating to the position where the sampling rod and the fixing rod form an angle of 90°, that is, the sampling rod and the fixing rod are perpendicular, and sampling is carried out through the sampling container.

[0055] (3) After sampling is completed, the fixed part is reset by operating the transmission part, and the sampling rod is simultaneously driven to rotate to a position parallel to the fixed rod, that is, the angle between the sampling rod and the fixed rod is 0°, and the sampling device is removed from the equipment tank, and the sampling is completed. During the entire sampling process, the sampling container always maintains an upward opening due to its own gravity.

[0056] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
