Description

Technical Field

[0001] This utility model relates to the field of installation equipment for anti-clogging samplers, and in particular to a locking structure for an anti-clogging sampler. Background Technology

[0002] In the installation of anti-clogging samplers for automated wind pressure measurement instruments in thermal power generation, petroleum, and chemical industries, the samplers are often installed in a reserved steel pipe with an internal high-temperature airflow by direct on-site welding or flange connection. If welding is used, weld beads, slag, cracks, etc. are easily left at the weld hole, which can easily affect the operation of the equipment. Moreover, when the sampler is maintained or replaced, the weld seam needs to be cut and re-welded, which damages the structural integrity of the reserved steel pipe and increases downtime and maintenance costs. If flange connection is used, the sampler and the reserved steel pipe need to be welded to the matching flanges first, and then the two flanges are connected by bolts. The same problems will exist. In addition, the pipe diameter of the reserved steel pipe is of various specifications, and flanges of corresponding sizes need to be equipped, which has poor versatility. Utility Model Content To overcome the problems of direct welding or flange connection relying on welding processes, which can easily affect equipment operation, and the difficulties in replacement and poor versatility in the aforementioned background technologies, this utility model provides a locking structure for an anti-clogging sampler. The position of the moving slider on the stationary slider can be adjusted by adapting the diameter of the reserved steel pipe, thereby locking the locking structure inside the reserved steel pipe. This has the beneficial effects of eliminating the influence of welding, improving the convenience of sampler replacement, increasing replacement efficiency, and having a wide range of applications.

[0003] The technical solution of this utility model is as follows: A locking structure for an anti-clogging sampler is disclosed. The locking structure extends into a pre-reserved steel pipe and includes a through section and a connecting section. The sampler enters the pre-reserved steel pipe through the through section. The connecting section is located between the through section and the inner wall of the pre-reserved steel pipe and connects to both. The connecting section includes a movable slider and a stationary slider that are connected. The movable slider and the stationary slider can slide relative to each other to adjust the total thickness of the overlapping part and lock the locking structure to the pre-reserved steel pipe.

[0004] Compared with existing technologies, the beneficial effects of this technical solution are as follows: The moving slider and the through-hole can respectively abut against the inner wall of the reserved steel pipe. The locking structure is fixed inside the reserved steel pipe, and the sampler is installed inside the reserved steel pipe through the locking structure. There is no need to use welding process or flange connection. It solves the problems of welding or flange connection in the background technology, which rely on welding process, which can easily affect the operation of equipment and have the problems of difficult replacement and poor versatility. It has the advantages of eliminating the influence of welding, improving the convenience of daily inspection and maintenance, technical transformation, periodic installation, dismantling and replacement of sampler, and significantly increasing work efficiency. Moreover, the position of the moving slider on the stationary slider can be adjusted by the diameter of the reserved steel pipe opening, and the total thickness of the overlapping part of the two can be adjusted, so as to lock the locking structure in the reserved steel pipe. The locking structure has a wider range of applications.

[0005] Preferably, the contact surfaces of the stationary slider and the moving slider are both mutually cooperating inclined surfaces; the stationary slider is fixedly connected to the through portion, and the moving slider is connected to an adjustment device. By rotating the adjustment device, the moving slider can move relative to the stationary slider.

[0006] Its beneficial effects are as follows: by adjusting the moving direction of the moving slider on the stationary slider, the total thickness of the two at the overlapping part can be adjusted, the locking structure can be clamped in the reserved steel pipe, and it can adapt to reserved steel pipes with different pipe diameters; the adjusting device can control the moving direction and moving distance of the moving slider on the stationary slider, so that the locking structure can be clamped in the reserved steel pipe and adapted to reserved steel pipes with different pipe diameters.

[0007] More preferably, the adjusting device includes a screw, one end of which passes through and is threadedly fitted to the movable slider, and the other end is connected to an adjusting knob.

[0008] Its beneficial effect is that rotating the adjustment knob can drive the screw to rotate. When the screw moves, since the moving slider is connected to the stationary slider, the moving slider cannot follow the screw to rotate under the restriction of the stationary slider. It can only slide along the screw body on the stationary slider.

[0009] More preferably, the side of the moving slider away from the stationary slider is an arc-shaped surface, which can be fitted and connected with the inner wall of the reserved steel pipe.

[0010] Its beneficial effects are as follows: This arc-shaped surface structure design can make the connection between the moving slider and the reserved steel pipe more tight and reliable. The arc-shaped surface can be set as a rough surface, which can further increase the static friction between the slider and the inner wall of the reserved steel pipe.

[0011] More preferably, the through portion includes an outer arc tube and an inner circular tube. The inner circular tube is inserted into the outer arc tube through an opening on the surface of the outer arc tube. One side of the inner circular tube is fixedly connected to the inner wall of the outer arc tube, and the other side is fixed to the bottom surface of the static slider. The sampler passes through the inner circular tube, and the outer wall of the outer arc tube can be matched with the inner wall of the reserved steel pipe.

[0012] Its beneficial effects are as follows: the inner round tube can form a passage for the sampler and provide fixed support for the static slider; the open design of the outer arc tube provides installation space for the connection part and reduces the installation space occupied; the arc design of the outer arc tube can also make the connection with the reserved steel pipe tighter and more reliable.

[0013] More preferably, the bottom surface of the static slider is fixedly provided with a stabilizing strip, which extends along the length direction of the outer arc tube opening, and its bottom surface is fixedly connected to the inner circular tube, while its two sides are fixedly connected to the inner wall of the outer arc tube.

[0014] Its beneficial effects are as follows: the stabilizing strip is used to connect the static slider and the inner round tube, and its two sides are connected to the inner wall of the outer arc tube, which can enhance the stability of the overall structure.

[0015] More preferably, one end of the outer arc tube and the inner circular tube are simultaneously connected to an outer sealing plate, and the other end is simultaneously connected to an inner sealing plate. The outer sealing plate is located outside the reserved steel pipe and connected to the pipe end, while the inner sealing plate is located inside the reserved steel pipe.

[0016] Its beneficial effects are: the outer sealing plate and the inner sealing plate are used to install and connect the outer arc pipe and the inner round pipe.

[0017] More preferably, the outer sealing plate and the inner sealing plate are both fixed perpendicularly to the outer arc tube and the inner round tube, the tube openings at both ends of the inner round tube are respectively inserted into the outer sealing plate and the inner sealing plate, and the tube openings at both ends of the outer arc tube are fixed to the inner side of the outer sealing plate and the inner sealing plate.

[0018] Its beneficial effect is that this design allows the sampler to pass through only the inner tube and enter the reserved steel tube.

[0019] More preferably, the adjusting end of the screw of the adjusting device passes vertically through the outer sealing plate, and its adjusting knob is located on the outside of the outer sealing plate.

[0020] Its advantage lies in placing the adjustment knob outside the outer sealing plate, making it easier to adjust the screw.

[0021] More preferably, sealing rings are provided at the connection between the outer sealing plate and the screw and at the inlet of the inner tube; a high-temperature gasket is fixed on the side of the outer sealing plate near the reserved steel pipe.

[0022] Its beneficial effects are as follows: the sealing ring ensures the sealing of the connection, and the sealing ring at the inlet of the inner round tube can also make the sampler stably installed in the locking structure; the use of high temperature gaskets can achieve good sealing performance at the connection between the outer sealing plate and the reserved steel pipe opening.

Detailed Implementation To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1: As Figures 1 to 3 The diagram illustrates a locking structure for an anti-clogging sampler. The locking structure extends into a pre-reserved steel pipe 1 and includes a through section and a connecting section. The sampler 6 enters the pre-reserved steel pipe 1 through the through section to take a sample. The connecting section is located between the through section and the inner wall of the pre-reserved steel pipe 1 and connects to both. The connecting section includes a movable slider 31 and a stationary slider 32. The movable slider 31 can move along the stationary slider 32. When the movable slider 31 moves relative to the stationary slider 32, the total thickness of the overlapping portion changes; that is, the total thickness of the overlapping portion in the radial direction of the pre-reserved steel pipe 1 changes. Thus, the movable slider 31 and the through section can respectively abut against the inner wall of the pre-reserved steel pipe 1. The locking structure is fixed inside the pre-reserved steel pipe 1, while the sampler 6... The locking structure is installed inside the reserved steel pipe 1 without the need for welding or flange connections. This solves the problems of welding or flange connections in the background technology, which rely on welding processes, can easily affect equipment operation, and have difficulties in replacement and poor versatility. It eliminates the influence of welding, improves the convenience of daily inspection, maintenance, technical transformation, periodic installation, dismantling, and replacement of the sampler 6, and greatly increases work efficiency. Furthermore, the position of the moving slider 31 on the stationary slider 32 can be adjusted by adapting the diameter of the reserved steel pipe 1, thereby adjusting the total thickness of the overlapping part of the two, so as to lock the locking structure inside the reserved steel pipe 1. This has the beneficial effect of a wider range of adaptability for the locking structure.

[0026] Example 2: Based on Example 1, the stationary slider 32 and the moving slider 31 are optimized. One side of the moving slider 31 is an arc-shaped surface 311, and the other side is an inclined surface 33. One side of the stationary slider 32 is an inclined surface 33, and the other side is a flat surface. The contact surfaces of the stationary slider 32 and the moving slider 31 are the mutually cooperating inclined surfaces 33. When the two are facing each other, the inclined surfaces 33 tilt in the same direction. When the moving slider 31 moves along the stationary slider 32 in a direction where the thickness of the stationary slider 32 gradually increases, the thickness of the two at the overlapping part gradually increases, and vice versa. Thus, by adjusting the movement direction of the moving slider 31 on the stationary slider 32, the total thickness of the two at the overlapping part can be adjusted, thus locking the locking structure in the reserved steel pipe 1 and adapting to reserved steel pipes 1 with different pipe diameters. In addition, the stationary slider 32 and the moving slider 31 can be adapted to the usage scenario of the reserved steel pipe 1, conforming to the specification and size range of the reserved steel pipe 1 under that usage scenario. The stationary slider 32 is fixedly connected to the through section, and the movable slider 31 is connected to an adjustment device. By rotating the adjustment device, the movable slider 31 can move relative to the stationary slider 32. The adjustment device can control the direction and distance of movement of the movable slider 31 on the stationary slider 32, thereby locking the locking structure inside the reserved steel pipe 1 and adapting it to reserved steel pipes 1 with different pipe diameters. Specifically, the adjustment device includes a screw 4. One end of the screw 4 passes through the movable slider 31 and is threadedly assembled with it, and the other end is connected to an adjustment knob 41. The adjustment knob 41 can be a nut. Rotating the adjustment knob 41 will drive the screw 4 to rotate. When the screw 4 rotates, since the movable slider 31 is connected to the stationary slider 32, under the restriction of the stationary slider 32, the movable slider 31 cannot follow the rotation of the screw 4, but can only slide along the body of the screw 4 on the stationary slider 32.

[0027] Preferably, the side of the movable slider 31 away from the stationary slider 32 is an arc-shaped surface 311. The arc-shaped surface 311 is in contact with the inner wall of the reserved steel pipe 1. This structural design can make the connection between the movable slider 31 and the reserved steel pipe 1 tighter and more reliable. The arc-shaped surface 311 can be set as a rough surface, which can further increase the static friction between it and the inner wall of the reserved steel pipe 1.

[0028] Preferably, the through section includes an outer arc tube 21 and an inner circular tube 22. An opening 211 is formed on one side of the outer arc tube 21 along its length. The inner circular tube 22 can be inserted into the outer arc tube 21 through the opening 211 on the tube surface of the outer arc tube 21, that is, the inner circular tube 22 is placed into the outer arc tube 21. Both extend in the same direction. The outer wall of one side of the inner circular tube 22 is fixed to the inner wall of the outer arc tube 21 by welding, while the outer wall of the opposite side is fixed to the bottom surface of the static slider 32. The sampler 6 passes through the inner circular tube 22, and the outer arc tube 22... The outer wall of tube 21 is connected to the inner wall of the reserved steel pipe 1. The inner round tube 22 can form a passage for the sampler 6 and also provide fixed support for the static slider 32. The opening 211 design of the outer arc tube 21 provides installation space for the connection part and reduces the installation space occupied. The arc design of the outer arc tube 21 can also make the connection with the reserved steel pipe 1 tighter and more reliable. The connection surface with the reserved steel pipe 1 can be set as a rough surface, which can further increase the static friction between the tube and the inner wall of the reserved steel pipe 1.

[0029] In a further preferred embodiment, the stationary slider 32 is located inside the opening 211 of the outer arc tube 21, and a stabilizing strip 34 is fixed to its bottom surface by welding. The stabilizing strip 34 extends along the length direction of the opening 211 of the outer arc tube 21, and its bottom surface is fixed to the outer wall of the inner circular tube 22 by welding, while its two sides are fixed to the inner wall of the outer arc tube 21 by welding. The stabilizing strip 34 is used to connect the stationary slider 32 and the inner circular tube 22, and its two sides are fixed to the inner wall of the outer arc tube 21, which can enhance the stability of the overall structure.

[0030] Preferably, one end of the outer arc tube 21 and the inner round tube 22 are connected to an outer sealing plate 51, and the other end is connected to an inner sealing plate 52. The outer sealing plate 51 is located outside the reserved steel pipe 1 and is pressed onto the end of the reserved steel pipe 1. The inner sealing plate 52 is located inside the reserved steel pipe 1. The outer sealing plate 51 and the inner sealing plate 52 are used to install and connect the outer arc tube 21 and the inner round tube 22. The outer sealing plate 51 can be designed with a larger area to further increase the versatility of the locking structure.

[0031] Specifically, the outer sealing plate 51 and the inner sealing plate 52 are both fixed perpendicularly to the outer arc tube 21 and the inner circular tube 22. The tube openings at both ends of the inner circular tube 22 are inserted into the outer sealing plate 51 and the inner sealing plate 52 respectively and fixed inside the sealing plate. The tube openings at both ends of the outer arc tube 21 are welded and fixed to the inner side of the outer sealing plate 51 and the inner sealing plate 52, and abut against the sealing plate. This design allows the sampler 6 to pass through the inner circular tube 22 and enter the reserved steel pipe 1.

[0032] Preferably, the adjusting end of the screw 4 of the adjusting device passes vertically through the outer sealing plate 51, and the adjusting knob 41 connected to the adjusting end is located on the outside of the outer sealing plate 51. Arranging the adjusting knob 41 outside the outer sealing plate 51 makes it easier to adjust the screw 4.

[0033] Preferably, sealing rings 53 are provided at the connection between the outer sealing plate 51 and the screw 4, and at the inlet of the inner tube 22. The sealing rings 53 can be metal sealing rings, specifically metal O-rings. These metal O-rings are filled with an inert gas (such as helium) and treated with a coating. Under pressure, they undergo elastoplastic deformation, creating a "pressure energy conversion" effect to enhance sealing. The sealing ring 53 on the outer sealing plate 51 is fixed to the surface of the outer sealing plate 51. The screw 4 passes through the sealing ring 53, and its top end is not threaded circumferentially. It fits tightly inside the sealing ring 53, ensuring a tight seal at this point, while also allowing the screw 4 to rotate normally.

[0034] Similarly, a sealing ring 53 is fixed at the inlet of the inner tube 22. The sampler 6 passes through the sealing ring 53 into the inner tube 22 to ensure the sealing at this point. The sealing ring 53 at this point also allows the sampler 6 to be stably installed in the locking structure. The size of the conduit into the inner tube 22 of the sampler 6 is usually uniform, so the sealing ring 53 at this point can seal most samplers 6. If a sampler 6 of a different size is encountered, only the sealing ring 53 needs to be replaced.

[0035] In addition, a high-temperature gasket 54 is fixed on the side of the outer sealing plate 51 near the reserved steel pipe 1. The high-temperature gasket 54 is a sealing component used in the industrial field for extreme temperature conditions. It has excellent sealing performance. Combined with the weight of the outer sealing plate 51 itself, the connection between the outer sealing plate 51 and the pipe opening of the reserved steel pipe 1 can achieve good sealing performance.

[0036] When installing the anti-blocking sampler 6, first insert the locking structure into the installation position of the reserved steel pipe 1. The outer wall of the outer arc tube 21 can be connected to the inner wall of the reserved steel pipe 1 first. Then, press the outer sealing plate 51 to the opening of the reserved steel pipe 1 to ensure the sealing at this point. Next, the adjustment knob 41 can be turned by the torque wrench. The screw 4 follows the adjustment knob 41 and moves the moving slider 31 along the stationary slider 32 in the direction where the thickness of the stationary slider 32 gradually increases. The arc surface 311 of the stationary slider 32 is connected to the inner wall of the reserved steel pipe 1. Continue to turn the adjustment knob 41 until the arc surface 311 of the stationary slider 32 and the outer wall of the outer arc tube 21 are firmly abutted against the inner wall of the reserved steel pipe 1. At this time, the adjustment knob 41 can no longer be turned. Therefore, the outer sealing plate 51, when used in conjunction with the connecting part, can clamp and fix the locking structure inside the reserved steel pipe 1. The locking structure cannot rotate or move up and down inside the reserved steel pipe 1, and can be stably installed inside the reserved steel pipe 1.

[0037] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
