Description

Technical Field

[0001] This utility model belongs to the field of sampling equipment technology, specifically a sampling support device for waste gas from a fixed pollution source. Background Technology

[0002] Fixed-point pollution source exhaust gas sampling is a professional monitoring activity conducted on exhaust gas emitted from fixed locations (such as factory chimneys, boiler exhaust stacks, etc.). Operators use professional sampling devices at specific locations according to the specifications to collect exhaust gas samples at set durations and frequencies, accurately obtaining concentration data of pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides.

[0003] When sampling exhaust gas from fixed pollution sources, tripods are generally used to support and fix the sampling gun. Although tripods can provide support and fixation, their simple structure and lack of design for adjusting the tilt of the sampling gun make it difficult for sampling personnel to flexibly and accurately adjust the tilt angle of the sampling gun head according to actual sampling needs and on-site environmental conditions. This deficiency becomes particularly prominent in some complex sampling scenarios, greatly reducing the flexibility of the support device. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a fixed-point pollution source exhaust gas sampling support device, which has the advantage of adjustable tilt angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-point pollution source exhaust gas sampling support device, comprising a housing, a lifting plate movably installed on the top of the housing, side plates fixedly installed on the front and rear sides of the top of the lifting plate, a movable shaft movably sleeved between the side plates, a connecting plate fixedly sleeved on the outer surface of the movable shaft, a lead screw fixedly connected to the top of the connecting plate, a circular sleeve threaded onto the outer surface of the lead screw, a sampling gun body fixedly connected to the top of the circular sleeve, a gear fixedly sleeved on the outer surface of the movable shaft, a threaded rod movably sleeved inside the lifting plate, a moving plate threadedly sleeved on the outer surface of the threaded rod, the outer surface of the moving plate movably connected to the inner surface of the lifting plate, a toothed plate fixedly connected to the top of the moving plate, the top of the toothed plate meshing with the outer surface of the gear, and a rotating block fixedly sleeved on the right side of the outer surface of the threaded rod.

[0006] As a preferred embodiment of this utility model, the front and rear sides of the movable plate are movably sleeved with limit rods, the outer surface of the limit rods is fixedly sleeved with the inner wall of the lifting plate, and a circular groove is provided on the front of the box.

[0007] As a preferred embodiment of this utility model, a vertical plate is fixedly installed on the rear side of the bottom of the lifting plate, and a rectangular frame is fixedly connected to the bottom end of the vertical plate.

[0008] As a preferred embodiment of this utility model, a support rod is fixedly installed at the bottom of the inner surface of the box, and a round shaft is movably sleeved inside the top of the support rod. The front end of the round shaft extends to the front of the box and is movably sleeved with the inner wall of the box.

[0009] As a preferred embodiment of this utility model, a disc located inside the housing is fixedly sleeved on the outer surface of the circular shaft, and a circular block is fixedly sleeved inside the bottom end of the disc. The rear end of the circular block extends into the interior of the rectangular frame and is movably connected to the inner surface of the rectangular frame.

[0010] As a preferred embodiment of this utility model, a rotating plate located on the front of the housing is fixedly sleeved on the outer surface of the circular shaft, and a bolt is threaded on the inner top of the rotating plate, with the outer surface of the bolt movably sleeved with the inner surface of the circular groove.

[0011] As a preferred embodiment of this utility model, vertical rods are fixedly installed on both the left and right sides of the bottom front side of the lifting plate, and a limit block is movably sleeved on the top of the outer surface of the vertical rod, and the outer surface of the limit block is fixedly connected to the inner surface of the box.

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

[0013] 1. This utility model, by setting up a movable shaft, connecting plate, gear, and lifting plate, and by rotating the rotating block, causes the threaded rod to drive the movable plate to move under the limiting action of the limiting rod, thereby driving the toothed plate to move. When the toothed plate moves, it will drive the gear to rotate, which will drive the movable shaft and connecting plate to rotate, thereby driving the sampling gun body to rotate through the lead screw and sleeve, thus adjusting the tilt angle of the sampling gun body. This allows for adjustment according to actual usage, improving the flexibility of the device.

[0014] 2. This utility model sets up a rectangular frame, a disc, a circular block, and a rotating plate. The operator rotates the rotating plate, causing the circular shaft to drive the disc to rotate. At this time, the circular block will rotate around the circular shaft, thereby squeezing and pushing the inner surface of the rectangular frame and driving the rectangular frame to move upward. This causes the vertical plate to drive the lifting plate to rise, thereby achieving the purpose of adjusting the height of the sampling gun body. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a sampling support device for waste gas from a fixed pollution source, including a housing 1. A lifting plate 2 is movably installed on the top of the housing 1. Side plates 3 are fixedly installed on the front and rear sides of the top of the lifting plate 2. A movable shaft 4 is movably sleeved between the side plates 3. A connecting plate 5 is fixedly sleeved on the outer surface of the movable shaft 4. A lead screw 6 is fixedly connected to the top of the connecting plate 5. A circular sleeve 7 is threaded onto the outer surface of the lead screw 6. A sampling gun body 8 is fixedly connected to the top of the circular sleeve 7. A gear 9 is fixedly sleeved on the outer surface of the movable shaft 4. A threaded rod 10 is movably sleeved inside the lifting plate 2. A moving plate 11 is threaded onto the outer surface of the threaded rod 10. The outer surface of the moving plate 11 is movably connected to the inner surface of the lifting plate 2. A toothed plate 12 is fixedly connected to the top of the moving plate 11. The top of the toothed plate 12 meshes with the outer surface of the gear 9. A rotating block 13 is fixedly sleeved on the right side of the outer surface of the threaded rod 10.

[0023] The operator places the sleeve 7 on the outer surface of the lead screw 6 and rotates the sleeve 7 to connect the lead screw 6 and the sleeve 7, thus completing the installation of the sampling gun body 8. When the operator rotates the rotating block 13, the rotating block 13 will drive the threaded rod 10 to rotate, causing the threaded rod 10 to drive the moving plate 11 and the toothed plate 12 to move. Since the outer surface of the toothed plate 12 meshes with the outer surface of the gear 9, the toothed plate 12 can drive the gear 9 and the movable shaft 4 to rotate when it moves, causing the movable shaft 4 to drive the connecting plate 5 to rotate, thereby adjusting the tilt angle of the sampling gun body 8.

[0024] Among them, the front and rear sides of the movable plate 11 are movably sleeved with limit rods 14, the outer surface of the limit rods 14 is fixedly sleeved with the inner wall of the lifting plate 2, and the front of the box 1 is provided with a circular groove 23.

[0025] By setting the limit rod 14, the limit rod 14 can limit the movement of the moving plate 11, making the moving plate 11 move more stably.

[0026] Among them, a vertical plate 15 is fixedly installed on the rear side of the bottom of the lifting plate 2, and a rectangular frame 16 is fixedly connected to the bottom end of the vertical plate 15.

[0027] When the rectangular frame 16 moves upward, it will cause the vertical plate 15 to rise, which in turn causes the lifting plate 2 to move upward, thereby adjusting the height of the sampling gun body 8.

[0028] Among them, a support rod 17 is fixedly installed on the bottom of the inner surface of the box 1, and a round shaft 18 is movably sleeved inside the top of the support rod 17. The front end of the round shaft 18 extends to the front of the box 1 and is movably sleeved with the inner wall of the box 1.

[0029] By setting the support rod 17, the support rod 17 serves to install and support the round shaft 18.

[0030] Among them, a disc 19 located inside the housing 1 is fixedly sleeved on the outer surface of the circular shaft 18, and a circular block 20 is fixedly sleeved on the bottom end of the disc 19. The rear end of the circular block 20 extends into the interior of the rectangular frame 16 and is movably connected to the inner surface of the rectangular frame 16.

[0031] When the disc 19 rotates, the block 20 will rotate around the axis 18, thereby squeezing and pushing the inner surface of the rectangular frame 16, which in turn drives the rectangular frame 16 to move upward.

[0032] Among them, the outer surface of the round shaft 18 is fixedly sleeved with a rotating plate 21 located on the front of the housing 1, and the inner thread of the top of the rotating plate 21 is sleeved with a bolt 22, and the outer surface of the bolt 22 is movably sleeved with the inner surface of the round groove 23.

[0033] By rotating the rotating plate 21, the circular shaft 18 can be driven to rotate. When the bolt 22 is inserted into the circular groove 23, it will fix the rotating plate 21.

[0034] Vertical rods 25 are fixedly installed on both the left and right sides of the bottom front side of the lifting plate 2. The top of the outer surface of the vertical rod 25 is movably sleeved with a limit block 24, and the outer surface of the limit block 24 is fixedly connected to the inner surface of the box 1.

[0035] When the lifting plate 2 rises, it will drive the vertical rod 25 to rise along the inner surface of the limiting block 24, thereby making the lifting plate 2 rise more stably.

[0036] Working principle and usage process of this utility model:

[0037] The operator places the sleeve 7 on the outer surface of the lead screw 6 and rotates the sleeve 7 to connect the lead screw 6 and the sleeve 7, thus completing the installation of the sampling gun body 8. When it is necessary to adjust the tilt angle of the sampling gun body 8, the rotating block 13 can be rotated to cause the threaded rod 10 to drive the moving plate 11 to move under the limiting action of the limiting rod 14. This causes the moving plate 11 to drive the toothed plate 12 to move. Since the outer surface of the toothed plate 12 meshes with the outer surface of the gear 9, the toothed plate 12 can drive the gear 9 to rotate when it moves. This causes the gear 9 to drive the connecting plate 5 to rotate through the movable shaft 4. This causes the connecting plate 5 to drive the sampling gun body 8 to rotate through the lead screw 6 and the sleeve 7, thereby adjusting the tilt angle of the sampling gun body 8.

[0038] When the height of the sampling gun body 8 needs to be adjusted, the bolt 22 can be rotated to disengage it from the inside of the circular groove 23, thereby releasing the fixing effect on the rotating plate 21. At this time, rotating the rotating plate 21 will drive the circular shaft 18 and the disc 19 to rotate. The disc 19 will drive the circular block 20 to rotate, causing the circular block 20 to press and push the inner surface of the rectangular frame 16 and drive the rectangular frame 16 to rise. The rectangular frame 16 will drive the lifting plate 2 to rise through the vertical plate 15, thereby causing the sampling gun body 8 to move upward and thus adjusting the height of the sampling gun body 8. After the adjustment is completed, the bolt 22 is rotated again to insert it into the inside of the circular groove 23, thereby fixing the rotating plate 21 and fixing the disc 19, thus keeping the sampling gun body 8 at the current height.
