[0027] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and not used to limit the utility model.

[0028] The embodiment of the utility model provides a kind of exhaust device, as shown in Figure 1 And Figure 2 As shown, including cover 1, exhaust telescopic arm 2, support 3, drive mechanism 4 and baffle 5, cover 1 has lower opening 11, exhaust telescopic arm 2 passes through lower opening 11 and enters cover 1, support 3 is located in cover 1, drive mechanism 4 is connected between support 3 and exhaust telescopic arm 2, drive mechanism 4 is configured to drive exhaust telescopic arm 2 to move horizontally, exhaust telescopic arm 2 is connected with baffle 5 for shielding lower opening 11, the projection of baffle 5 covers the projection of lower opening 11 along vertical direction, and the projection area of baffle 5 is greater than the projection area of lower opening 11.

[0029] The exhaust device provided by the embodiment of the utility model can be used to adjust the horizontal position of exhaust telescopic arm 2 using drive mechanism 4 when in use, and then change the horizontal position of exhaust end 21 on exhaust telescopic arm 2, the exhaust end 21 of exhaust telescopic arm 2 is not limited to swing in fixed vertical plane. During adjustment, since the projection of baffle 5 covers the projection of lower opening 11 along vertical direction, and the projection area of baffle 5 is greater than the projection area of lower opening 11, baffle 5 can shield lower opening 11 of cover 1.

[0030] Therefore, the horizontal position of the exhaust telescopic arm 2 in the exhaust device provided by the first aspect of the present application can be adjusted, the exhaust end 21 of the exhaust telescopic arm 2 has better flexibility, and the exhaust effect of the laboratory can be easily ensured, and the experimental personnel have a larger experimental operation range.

[0031] In addition, the exhaust telescopic arm 2 moves relative to the lower opening 11 during horizontal movement, and therefore the lower opening 11 needs to be relatively large to avoid hindering the movement of the exhaust telescopic arm 2, and because waterway, gasway, circuit and other structures need to be arranged in the cover 1, a relatively large opening will cause certain safety hazards. In the process of adjusting the horizontal position of the exhaust telescopic arm 2 in the above embodiment, the shielding plate 5 can shield the lower opening 11, and the parts in the cover 1 will not fall out of the lower opening 11, and the use process is safer and more reliable.

[0032] In an optional embodiment, the size of the projection surface of the shielding plate 5 in the horizontal X direction is greater than the size of the projection surface of the lower opening 11 in the horizontal X direction, so that the shielding plate 5 can shield the lower opening 11 when the exhaust telescopic arm 2 moves in the horizontal X direction.

[0033] In an optional embodiment, the size of the projection surface of the shielding plate 5 in the horizontal Y direction is greater than the size of the projection surface of the lower opening 11 in the horizontal Y direction, and the horizontal Y direction is perpendicular to the horizontal X direction, so that the shielding plate 5 can shield the lower opening 11 when the exhaust telescopic arm 2 moves in the horizontal Y direction.

[0034] In an optional embodiment, as shown in Figure 1 and Figure 2 The shielding plate 5 is located in the cover 1, so that the edge of the shielding plate 5 can be hidden in the cover 1.

[0035] Specifically, the shielding plate 5 can be welded with the exhaust telescopic arm 2, or connected through screws and the like.

[0036] When the shielding plate 5 is located in the cover 1, a gasket can be arranged between the bottom surface of the shielding plate 5 and the inner surface of the cover 1, so that the shielding plate 5 and the cover 1 are prevented from directly rubbing.

[0037] The material of the gasket can be rubber or plastic.

[0038] It should be noted that any structure capable of driving the horizontal movement of the exhaust telescopic arm 2 can be the driving mechanism 4 provided in the above embodiment, for example, the driving mechanism 4 includes at least one structure such as a pneumatic cylinder, a hydraulic cylinder, a linear motor or the like for linear motion, or the driving mechanism 4 adopts a combination of a rotary motor and a transmission assembly for rotary motion, the transmission assembly can convert rotary motion into linear motion, and the transmission assembly can be a gear and rack assembly or a screw and nut assembly.

[0039] In optional embodiments, as shown in Figure 1 The driving mechanism 4 comprises a first driving assembly 41 and a mounting base 42. The first driving assembly 41 is mounted on the support 3, and the mounting base 42 is slidingly connected with the support 3 along the horizontal X direction. The first driving assembly 41 is connected with the mounting base 42 to drive the mounting base 42 to move along the horizontal X direction. The exhaust telescopic arm 2 is connected with the mounting base 42.

[0040] In use, the first driving assembly 41 can drive the mounting base 42 to move along the horizontal X direction. Since the exhaust telescopic arm 2 is connected with the mounting base 42, the exhaust telescopic arm 2 can be synchronously driven to move along the horizontal X direction.

[0041] In optional embodiments, as shown in Figure 1 The first driving assembly 41 comprises a first motor 411 and a first screw rod 412. The first motor 411 is mounted on the support 3 through a connecting member such as a screw. One end of the first screw rod 412 is connected with the power output end of the first motor 411, and the other end of the first screw rod 412 is threadedly connected with the mounting base 42.

[0042] In use, the first motor 411 is started to drive the first screw rod 412 to rotate. Since the first screw rod 412 is threadedly connected with the mounting base 42, the mounting base 42 is slidingly connected with the support 3 along the horizontal X direction. During the rotation of the first screw rod 412, the mounting base 42 can be driven to slide along the horizontal X direction relative to the support 3, so as to adjust the position of the exhaust telescopic arm 2 in the above direction.

[0043] The first driving assembly 41 has a simple structure. Compared with the first driving assembly 41 using a pneumatic cylinder or a hydraulic cylinder, no additional gas path or oil path is needed, and the first driving assembly 41 is more convenient to arrange.

[0044] In optional embodiments, as shown in Figure 1 The support 3 comprises two horizontally arranged cross beams 31 and a vertical beam 32 connected between the two cross beams 31. The extending direction of the cross beam 31 is parallel to the horizontal X direction. The first motor 411 in the first driving assembly 41 is mounted on the vertical beam 32.

[0045] In the support 3, the vertical beam 32 can connect the two cross beams 31 to strengthen the structural stability of the support 3, and provide a mounting position for the first motor 411.

[0046] Specifically, as shown in Figure 1 The two horizontally arranged cross beams 31 are provided with sliding grooves 311 on the surfaces opposite to each other. The mounting base 42 is slidingly connected with the sliding grooves 311.

[0047] The above arrangement can make the mounting base 42 slidingly connected between the two cross beams 31, and the sliding process has good stability.

[0048] The portion of the mounting base 42 that extends into the slide groove 311 may be equipped with rollers, which can reduce the friction between the mounting base 42 and the slide groove 311.

[0049] To facilitate the mounting base 42 to be assembled between the two crossbeams 31, the sliding groove 311 on the crossbeam 31 can extend to the end face of the crossbeam 31, and the mounting base 42 can slide into the sliding groove 311 from the end face of the two crossbeams 31 to achieve sliding engagement with the two crossbeams 31.

[0050] In an optional embodiment, to make the horizontal adjustment range of the exhaust telescopic arm 2 larger, the drive mechanism 4 further includes a second drive component 43 and a connecting block 44; the second drive component 43 is mounted on the mounting base 42, and the connecting block 44 slides in cooperation with the mounting base 42 along the horizontal Y direction, the horizontal Y direction being perpendicular to the horizontal X direction; the second drive component 43 is connected to the connecting block 44 to drive the connecting block 44 to move along the horizontal Y direction, and the exhaust telescopic arm 2 is connected to the connecting block 44.

[0051] In the above embodiment, the exhaust telescopic arm 2 is connected to the mounting base 42 via a connecting block 44 and a second drive assembly 43. During use, the second drive assembly 43 can drive the connecting block 44 to move horizontally in the Y direction. Since the exhaust telescopic arm 2 is connected to the connecting block 44, the exhaust telescopic arm 2 can move synchronously in the horizontal Y direction.

[0052] In alternative implementations, such as Figure 1 As shown, the second drive assembly 43 includes a second motor 431 and a second screw 432. The second motor 431 is mounted on the mounting base 42. One end of the second screw 432 is connected to the power output end of the second motor 431, and the other end of the second screw 432 is threadedly engaged with the connecting block 44.

[0053] When in use, the second motor 431 starts and drives the second screw 432 to rotate. Since the second screw 432 is threadedly engaged with the connecting block 44, and the connecting block 44 is slidably engaged with the mounting base 42 along the horizontal Y direction, the second screw 432 can drive the connecting block 44 to slide relative to the mounting base 42 along the horizontal Y direction during rotation, thereby adjusting the position of the exhaust telescopic arm 2 in the above direction.

[0054] The second drive assembly 43, in conjunction with the first drive assembly 41, enables the exhaust telescopic arm 2 to move in the horizontal X and Y directions, thereby giving the exhaust end 21 of the exhaust telescopic arm 2 a larger adjustment range.

[0055] In alternative implementations, such as Figure 1 As shown, the mounting base 42 has a through groove 421, the extension direction of the through groove 421 is parallel to the horizontal Y direction, and the connecting block 44 passes through the through groove 421 and is connected to the exhaust telescopic arm 2.

[0056] The through slot 421 can be a rectangular slot or a waist-shaped slot.

[0057] Specifically, the end of the connecting block 44 matched with the second screw rod 432 is located above the mounting seat 42, the end of the connecting block 44 connected with the exhaust telescopic arm 2 is located below the mounting seat 42, and the connecting block 44 can be loaded on the top surface of the mounting seat 42, so that the weight of the exhaust telescopic arm 2 can be applied to the support 3 through the mounting seat 42, and the second motor 431 does not need to bear the weight of the exhaust telescopic arm 2.

[0058] Specifically, the connecting block 44 can be provided with a roller, and the roller is loaded on the top surface of the mounting seat 42, so that the friction between the connecting block 44 and the mounting seat 42 can be reduced.

[0059] The second aspect of the embodiment of the utility model provides a hoisting system, and the hoisting system provided by the second aspect of the embodiment of the utility model comprises the exhaust device.
