Description

Technical Field

[0001] This utility model belongs to the field of waste gas sampling technology, and specifically relates to a pollution source waste gas sampling device that is easy to install. Background Technology

[0002] As one of the main sources of air pollutants, industrial waste gas emissions inevitably lead to a decline in air quality, causing serious harm to human health and huge losses to the national economy. In order to effectively control pollution sources and ensure that waste gas emissions meet standards, it is necessary to install waste gas sampling devices at the waste gas emission outlets and assess the emission status through the collected data.

[0003] Existing exhaust gas sampling devices are mainly installed on the pipe ports for exhaust gas discharge via brackets. In order to enable the exhaust gas sampling device to better collect and detect the emitted exhaust gas, it is usually installed inside the bracket. This installation method means that when the sampling device is inspected and maintained in the future, the bracket needs to be removed from the inside of the pipe before the exhaust gas sampling device can be moved out of the pipe. The whole operation process is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] To address the problems of cumbersome, time-consuming, and labor-intensive disassembly of exhaust gas sampling devices from inside pipelines, this utility model proposes an easy-to-install exhaust gas sampling device for pollution sources, thereby overcoming the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pollution source exhaust gas sampling device that is easy to install, including a mounting plate. An adjustable support component and a connecting component are sequentially arranged on the outer side of the mounting plate. The adjustable support component and the connecting component are rotatably connected. A locking component is arranged on the outer side of the connecting component. A sampling device is arranged on the inner side of the mounting plate. An elastic sleeve component is arranged between the sampling device and the mounting plate.

[0007] By pulling the locking end of the locking component, the adjustable support component causes the sampling device to flip via the mounting plate. By pulling the sleeve end of the elastic sleeve component, the sampling device is disengaged from the mounting plate.

[0008] Furthermore, the adjustable support assembly includes a support frame, two of which are symmetrically arranged on the outer side of the mounting plate. An adjusting screw is rotatably connected inside the support frame, and an adjusting frame is threadedly connected to the outer side of the adjusting screw. A sleeve frame is fitted onto the outer side of the support frame, and one end of the adjusting frame is fixedly connected to the top of the inner wall of the sleeve frame.

[0009] Furthermore, the mounting plate has an adjustment groove inside, one end of the two adjustment screws extends into the adjustment groove, the threads on the two adjustment screws are opposite, a T-shaped adjustment rod is rotatably connected to the front of the mounting plate, the bottom end of the T-shaped adjustment rod extends into the adjustment groove, and bevel gears are fixedly connected to the outer surfaces of the T-shaped adjustment rod and the two adjustment screws, the three bevel gears meshing together.

[0010] Furthermore, the connecting assembly includes a rotating rod, which is fixedly connected to the top of the sleeve frame. An arc-shaped connecting plate is rotatably connected to the top of the rotating rod, and the top of the arc-shaped connecting plate has a mounting hole.

[0011] Furthermore, the locking assembly includes a locking hole located on the outside of the rotating rod. A locking rod is movably connected inside the locking hole. A support plate is fixedly connected to the bottom of the arc-shaped connecting plate. A storage cylinder is fixedly connected to one side of the support plate. A push plate is movably connected inside the storage cylinder. One end of the locking rod passes through the support plate and the storage cylinder. The push plate is fixedly connected to the locking rod. A locking spring is fixedly connected between the push plate and the inner wall of the storage cylinder. A pull plate is fixedly connected to one end of the locking rod.

[0012] Furthermore, the elastic socket assembly includes a socket groove, which is formed inside the mounting plate. A socket block is movably connected inside the socket groove. The adjusting block is fixedly connected to the sampling device. A fixing groove is formed on the inner wall of the socket groove. The fixing groove passes through the socket block and extends out from the inside of the mounting plate. A fixing plate is movably connected inside the fixing groove. A pulling frame is provided on the outer side of the mounting plate. The fixing plate is fixedly connected to the pulling frame.

[0013] Furthermore, the mounting plate has a storage cavity inside, and a limiting plate is movably connected inside the storage cavity. A pull rod is fixedly connected to one side of the limiting plate, and one end of the pull rod passes through the mounting plate and is fixedly connected to the pull frame. A fixing spring is fixedly connected between the limiting plate and the inner wall of the storage cavity.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model allows the adjustable support component to rotate the sampling device via the mounting plate by pulling the locking end of the locking component. Then, by pulling the fixed end of the elastic sleeve component, the sampling device can be detached from the mounting plate. The above arrangement ensures that the adjustable support component will not obstruct the disassembly of the sampling device, and the sampling device can be detached from the mounting plate simply by pulling the fixed end of the elastic sleeve component. The whole operation process is relatively convenient.

[0016] 2. This utility model uses a pulling frame to pull the fixing plate, allowing the fixing plate to move out of the fixing groove on the socket block. Simultaneously, under the pulling of the pulling frame, the pulling rod compresses the fixing spring through the limiting plate and moves continuously inside the receiving cavity. The above configuration allows the pulling frame to be pulled directly when the sampling device is removed from the mounting plate, making the operation convenient. At the same time, the stability of the fixing plate when limiting the socket block is also guaranteed by the pushing of the fixing spring.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a pollution source exhaust gas sampling device that is easy to install, including a mounting plate 1. An adjustable support component 2 and a connecting component 3 are sequentially arranged on the outer side of the mounting plate 1. The adjustable support component 2 and the connecting component 3 are rotatably connected. A locking component 4 is arranged on the outer side of the connecting component 3. A sampling device 5 is arranged on the inner side of the mounting plate 1. An elastic sleeve component 6 is arranged between the sampling device 5 and the mounting plate 1.

[0031] By pulling the locking end of the locking component 4, the adjustable support component 2 drives the sampling device 5 to flip via the mounting plate 1. By pulling the sleeve end of the elastic sleeve component 6, the sampling device 5 is disengaged from the mounting plate 1.

[0032] By adjusting the length of the adjustable support component 2, the connecting component 3 is brought into contact with the inner wall of the pipe, and then the connecting component 3 is fixed to the inner wall of the pipe. Then, the sampling device 5 is pressed and rolled onto the mounting plate 1 by the elastic sleeve component 6. Then, the locking component 4 is pulled, so that the adjustable support component 2 rotates under the drive of the rotating end of the connecting component 3. At the same time, the mounting plate 1 drives the sampling device 5 to flip, so that the sampling device 5 can rotate to the rear side of the adjustable support component 2.

[0033] By pulling the locking end of the locking component 4, the adjustable support component 2 causes the sampling device 5 to flip via the mounting plate 1. Then, by pulling the fixed end of the elastic sleeve component 6, the sampling device 5 can be detached from the mounting plate 1. The above arrangement ensures that the adjustable support component 2 will not obstruct the disassembly of the sampling device 5, and the sampling device 5 can be detached from the mounting plate 1 simply by pulling the fixed end of the elastic sleeve component 6. The whole operation process is relatively convenient.

[0034] In one embodiment, the adjustable support assembly 2 includes a support frame 201. Two support frames 201 are symmetrically arranged on the outside of the mounting plate 1. An adjusting screw 202 is rotatably connected inside the support frame 201. An adjusting frame 203 is threadedly connected to the outside of the adjusting screw 202. A sleeve frame 204 is sleeved on the outside of the support frame 201. One end of the adjusting frame 203 is fixedly connected to the top of the inner wall of the sleeve frame 204.

[0035] By driving the adjusting screw 202 to move the adjusting frame 203 inside the support frame 201, the moving adjusting frame 203 causes the sleeve frame 204 to move outside the support frame 201. This arrangement allows the length between the sleeve frame 204 and the support frame 201 to be adjusted according to the pipe specifications, thus enabling the sampling device 5 to be applied to pipes of various specifications. At the same time, the above arrangement ensures that the adjusting screw 202 can always be blocked, thereby preventing impurities carried in the exhaust gas from accumulating on the outside of the adjusting screw 202.

[0036] In one embodiment, for the aforementioned mounting plate 1, an adjustment groove 205 is provided inside the mounting plate 1, one end of the two adjustment screws 202 extends into the interior of the adjustment groove 205, the threads on the two adjustment screws 202 are opposite, a T-shaped adjustment rod 206 is rotatably connected to the front of the mounting plate 1, the bottom end of the T-shaped adjustment rod 206 extends into the interior of the adjustment groove 205, and bevel gears 207 are fixedly connected to the outer surfaces of the T-shaped adjustment rod 206 and the two adjustment screws 202, and the three bevel gears 207 mesh together.

[0037] The T-shaped adjusting rod 206 rotates one of the bevel gears 207, which in turn drives the two adjusting screws 202 to rotate synchronously through the two bevel gears 207 meshing with it. This allows the two socket frames 204 to move synchronously on the outside of the corresponding support frame 201. This arrangement makes it convenient to move the two socket frames 204. At the same time, when both socket frames 204 are fixed on the inner wall of the pipe, the mounting plate 1 can be collinear with the axis of the pipe, so that the subsequent sampling device 5 can better collect and detect the exhaust gas flowing out of the pipe.

[0038] In one embodiment, the connecting component 3 includes a rotating rod 301, which is fixedly connected to the top end of the sleeve frame 204. An arc-shaped connecting plate 302 is rotatably connected to the top end of the rotating rod 301, and an installation hole 303 is provided on the top of the arc-shaped connecting plate 302.

[0039] When the two socket frames 204 are driven, the two arc-shaped connecting plates 302 can move together. After the two arc-shaped connecting plates 302 come into contact with the inner wall of the pipe, the arc-shaped connecting plates 302 are fixed to the inner wall of the pipe by fixing bolts and mounting holes 303. When the socket frame 204 is rotated, the rotating rod 301 can rotate on the arc-shaped connecting plate 302 under the drive of the socket frame 204, so that the mounting plate 1 can be flipped normally.

[0040] In one embodiment, the locking assembly 4 includes a locking hole 401 located on the outside of the rotating rod 301. A locking rod 402 is movably connected inside the locking hole 401. A support plate 403 is fixedly connected to the bottom of the arc-shaped connecting plate 302. A storage cylinder 404 is fixedly connected to one side of the support plate 403. A push plate 405 is movably connected inside the storage cylinder 404. One end of the locking rod 402 passes through the support plate 403 and the storage cylinder 404. The push plate 405 is fixedly connected to the locking rod 402. A locking spring 406 is fixedly connected between the push plate 405 and the inner wall of the storage cylinder 404. A pull plate 407 is fixedly connected to one end of the locking rod 402.

[0041] The locking spring 406 can push the locking rod 402 through the pushing disc 405, so that the locking rod 402 can move directly into the locking hole 401. At this time, the locking rod 402 can lock the rotating rod 301, so that the rotating rod 301 will not rotate arbitrarily when the sampling device 5 is in normal operation. When it is necessary to disassemble the sampling device 5, the locking rod 402 can be pulled directly through the pulling plate 407, so that the locking rod 402 can press the locking spring 406 through the pushing disc 405. At the same time, the locking rod 402 moves directly out from the inside of the locking hole 401, and the rotating rod 301 can rotate normally. The above settings make the operation of rotating the mounting disc 1 more convenient.

[0042] In one embodiment, the elastic socket assembly 6 includes a socket groove 601, which is located inside the mounting plate 1. A socket block 602 is movably connected inside the socket groove 601. The socket block 602 is fixedly connected to the sampling device 5. A fixing groove 603 is provided on the inner wall of the socket groove 601. The fixing groove 603 passes through the socket block 602 and extends out from the inside of the mounting plate 1. A fixing plate 604 is movably connected inside the fixing groove 603. A pulling frame 605 is provided on the outer side of the mounting plate 1. The fixing plate 604 is fixedly connected to the pulling frame 605.

[0043] By moving the socket block 602 into the socket groove 601, the sampling device 5 can come into contact with the mounting plate 1. Then, by pulling the frame 605, the fixing plate 604 is pushed, so that the fixing plate 604 can move into the fixing groove 603 opened on the socket frame 204. At this time, under the restriction of the fixing plate 604 and the fixing groove 603, the socket block 602 will not arbitrarily detach from the inside of the socket groove 601.

[0044] In one embodiment, for the aforementioned mounting plate 1, the mounting plate 1 has a storage cavity 606 inside, and a limiting plate 607 is movably connected inside the storage cavity 606. A pull rod 608 is fixedly connected to one side of the limiting plate 607, and one end of the pull rod 608 passes through the mounting plate 1 and is fixedly connected to the pull frame 605. A fixing spring 609 is fixedly connected between the limiting plate 607 and the inner wall of the storage cavity 606.

[0045] The fixed spring 609 drives the pull rod 608 to move inside the storage cavity 606 via the limiting plate 607. The moving pull rod 608 then drives the fixed plate 604 to move via the pulling frame 605, so that the fixed plate 604 can move directly into the fixing groove 603 opened on the socket block 602. The setting of the fixed spring 609 ensures the stability of the fixed plate 604 when limiting the socket block 602. At the same time, when releasing the limitation on the socket block 602, the fixed plate 604 can be pulled directly by the pulling frame 605, which is relatively convenient.

[0046] Through the above technical solution, 1. By pulling the locking end of the locking component 4, the adjustable support component 2 causes the sampling device 5 to rotate via the mounting plate 1. Then, by pulling the fixed end of the elastic sleeve component 6, the sampling device 5 can be detached from the mounting plate 1. This arrangement ensures that the adjustable support component 2 will not obstruct the disassembly of the sampling device 5, and only the fixed end of the elastic sleeve component 6 needs to be pulled to detach the sampling device 5 from the mounting plate 1. The entire operation process is relatively convenient; 2. By pulling the bracket 605, the fixed plate is... Pulling 604 allows the fixing plate 604 to move out of the fixing groove 603 on the socket block 602. Simultaneously, under the pull of the pulling frame 605, the pulling rod 608 compresses the fixing spring 609 through the limiting plate 607 and moves continuously inside the receiving cavity 606. The above arrangement allows the pulling frame 605 to be pulled directly when the sampling device 5 is removed from the mounting plate 1, making the operation convenient. At the same time, the stability of the fixing plate 604 when limiting the socket block 602 is also guaranteed by the push of the fixing spring 609.
