[0021] Compared with the prior art, the present invention provides an intelligent demonstration platform for an intelligent conference room, which has the following beneficial effects:

[0022] 1. The intelligent demonstration platform for the smart conference room can automatically store the display screen through the lifting mechanism and blow away the impurities and dust attached to the outside of the display screen, reducing the cleaning workload of the staff and facilitating the direct use of the subsequent display screen when it is taken out. There is no need for the staff to clean it before use, thus improving the overall inspection work efficiency. When the display screen is stored, the demonstration table can be used for other purposes, making rational use of the demonstration table resources.

[0023] 2. The intelligent demonstration platform for the intelligent conference room drives the winding component to move when the lifting mechanism is working, so that the winding component drives the top plate to be stored vertically downward in the receiving groove when the display screen is in use, so as to avoid affecting other equipment placed around the demonstration table when the top plate is flipped and unfolded, thereby reducing the occupied area of ​​the device when the display screen is in use.

[0024] 3. The smart conference room uses a smart demonstration platform. When the display screen is lifted and lowered by the lifting mechanism, the rack on the sleeve meshes with the gear ring on the outside of the dehumidification box, so that the gear ring drives the dehumidification box to rotate, and the partition in the dehumidification box drives the desiccant inside to flip and roll, so that the desiccant particles in the dehumidification box can fully contact with the air to absorb moisture, preventing the desiccant from being left to accumulate and unable to fully contact with the air, affecting the drying effect, and preventing the display screen from being damaged by moisture.

[0025] 4. The intelligent demonstration platform for the intelligent conference room is driven by the meshing transmission of the active bevel gear on the outside and the driven bevel gear on the rotating shaft when the screw rotates. The driven bevel gear drives the rotating shaft and the cam to rotate. When the cam abuts against the force plate in the slide groove, it is pushed. When the first elastic element is deformed and the cam no longer abuts against the force plate, the force plate is reset under the action of the first elastic element, so that the force plate drives the moving plate to reciprocate on the top of the demonstration platform. When the moving plate moves, the connecting rod drives the nozzle to swing around the positioning rod as the center, so that the nozzle blows the impurities and dust attached to the outside of the display screen from different directions, blows away the impurities and dust attached to the display screen that are not easy to fall off, improves the dust and impurities cleaning effect, and ensures that the demonstration content of the demonstration platform is clear.

[0053] Specifically, when the lifting mechanism is working, the lifting motor 6 is controlled to run, and the output end of the lifting motor 6 drives the screw rod 601 to rotate in the demonstration platform 1, and the sleeve 602 outside the screw rod 601 moves axially along the screw rod 601 and drives the display screen 2 to move upward through the lifting plate 603.

[0054] Example 3: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 , an isotope tracing detection device, based on Example 2, further, the winding assembly includes a rotating rod 7 rotatably connected to the accommodating groove 4, a reel 701 arranged on the rotating rod 7, a pull rope 702 at one end fixedly connected to the reel 701 and wound around the reel 701, a secondary bevel gear 703 arranged at the end of the rotating rod 7, and a main bevel gear 6011 arranged on the screw rod 601 and meshing with the secondary bevel gear 703, and the end of the pull rope 702 away from the reel 701 is connected to the top plate 3.

[0055] Furthermore, a fixing rod 401 is fixed in the receiving groove 4, and a movable groove 302 matched with the fixing rod 401 is opened on the top plate 3, and a counterweight block 303 is provided at one end of the two top plates 3 that abut against each other.

[0056] Specifically, before the display screen 2 is used, the lifting motor 6 is controlled to run, and the output end of the lifting motor 6 drives the screw rod 601 to rotate in the demonstration platform 1. The sleeve 602 on the outside of the screw rod 601 moves along the axial direction of the screw rod 601 and drives the display screen 2 to move up through the lifting plate 603. When the screw rod 601 rotates, the main bevel gear 6011 meshes with the secondary bevel gear 703 on the rotating rod 7 for transmission, and the secondary bevel gear 703 drives the rotating rod 7 to rotate. The reel 701 on the outside of the rotating rod 7 reels the pull rope 702, and the pull rope 702 applies a force to the end of the top plate 3, and the top plate 3 is pulled by the pull rope. When 702 is pulled and the other end of the display screen 2 is moved upward, the top plate 3 rotates around the fixed rod 401. As the pull rope 702 is rolled up, the top plate 3 gradually moves into the accommodating groove 4, so that the top plate 3 is flipped and the display screen 2 is moved out of the demonstration platform 1 simultaneously, so that the display screen 2 can be put into use quickly, and a counterweight block 303 is provided at the end of the top plate 3, which can make the top plate 3 automatically fall down to close the demonstration platform 1 under the action of the counterweight block 3 when it is not pulled by the pull rope 702 and when the top plate 3 moves out of the accommodating groove 4, thereby covering and protecting the display screen 2 placed in the demonstration platform 1.

[0057] Example 4: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9, Fig.10 , Fig.11 and Fig.12 , an isotope tracing detection device, based on Example 3, further, the pneumatic part includes a sleeve 8 fixedly mounted on the bottom wall of the accommodating groove 4, a piston 801 slidably connected in the sleeve 8, a second elastic element 12 arranged between the piston 801 and the inner wall of the sleeve 8, and a connecting rod 802 with one end fixedly connected to the piston 801 and the other end connected to the top plate 3, the rod cavity of the sleeve 8 is provided with an inlet valve 803 and an outlet valve 804, the inlet valve 803 is connected to the outside of the demonstration platform 1 through a pipeline, and the outside of the outlet valve 804 is connected to an outlet pipe 805.

[0058] Furthermore, the connecting rod 802 includes a rod body 8021 fixedly connected to the piston 801 and a connecting ball 8022 arranged on the top of the rod body 8021 , and an arc groove 304 matching with the connecting ball 8022 is formed on the top plate 3 .

[0059] Furthermore, the dust removal unit includes a plurality of air distribution pipes 8051 arranged on the air outlet pipe 805, and one end of each air distribution pipe 8051 away from the air outlet pipe 805 is connected to a nozzle 806, a positioning rod 807 is arranged between the nozzle 806 and the top of the demonstration platform 1, and the nozzle 806 is rotatably connected to the positioning rod 807.

[0060] Specifically, when the winding assembly is winding the pull rope 702, the pull rope 702 applies a force to the end of the top plate 3. When the top plate 3 is pulled by the pull rope 702 and the other end of the top plate 3 is lifted up by the upwardly moved display screen 2, the top plate 3 rotates around the fixed rod 401. During this process, the connecting ball 8022 at the end of the rod body 8021 slides relative to the arc groove 304. As the pull rope 702 is wound, the pull rope 702 drives the top plate 3 to move downward in the accommodating groove 4. The top plate 3 exerts a force on the connecting rod 802, and the connecting rod 802 drives the piston 801 to move downward in the sleeve 8. The rod cavity of the sleeve 8 draws the external air of the demonstration platform 1 through the intake valve 803. When the winding assembly no longer winds the pull rope 702 and the display screen 2 is no longer wound, the top plate 3 rotates around the fixed rod 401. As the lifting mechanism moves downward and retracts to enter the demonstration platform 1, the connecting rod 802 drives the piston 801 to move upward in the sleeve 8, and the piston 801 squeezes the air in the rod cavity of the sleeve 8. The air in the rod cavity of the sleeve 8 is discharged to each branch air pipe 8051 through the air outlet pipe 805, and is blown to the outer side of the display screen 2 which gradually moves into the demonstration platform 1 through the nozzle 806 at the end of the branch air pipe 8051, so that the impurities and dust attached to the outer side of the display screen 2 are blown away when the display screen 2 is used, so as to ensure the clarity of the demonstration content on the front side of the display screen 2 and the heat dissipation effect of the surrounding side when the display screen 2 is used, reduce the cleaning workload of the staff, facilitate the direct use of the display screen 2 when it is taken out later, and do not need to be cleaned by the staff before use, thereby improving the overall detection work efficiency.

[0061] Example 5: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Fig.13 and Fig.14 , an isotope tracing detection device, based on Example 4, further, a rotating shaft 9 is rotatably connected in the demonstration platform 1, a driven bevel gear 901 is arranged on the rotating shaft 9, an active bevel gear 6012 meshing with the driven bevel gear 901 is arranged on the screw rod 601, a cam 902 is arranged at one end of the rotating shaft 9 away from the driven bevel gear 901, a slide groove 10 is opened in the demonstration platform 1, a force plate 1001 movably opposed to the cam 902 is slidably connected in the slide groove 10, a first elastic element 1002 is arranged between the force plate 1001 and the inner wall of the slide groove 10, a moving plate 11 sliding on the top of the demonstration platform 1 is fixedly provided on the top of the force plate 1001, and a connecting rod 111 is movably connected between the moving plate 11 and the nozzle 806.

[0062] Specifically, when the lifting mechanism drives the display screen 2 to be stored into the demonstration platform 1, the active bevel gear 6012 on the outside of the screw rod 601 meshes with the driven bevel gear 901 on the rotating shaft 9 for transmission, and the driven bevel gear 901 drives the rotating shaft 9 and the cam 902 to rotate. When the cam 902 abuts against the force plate 1001 in the slide groove 10, it is pushed, and the first elastic element 1002 is deformed. When the cam 902 no longer abuts against the force plate 1001, the force plate 1001 is reset under the action of the first elastic element 1002, so that the force plate 1001 drives the moving plate 11 to reciprocate on the top of the demonstration platform 1. When the moving plate 11 moves, the connecting rod 111 drives the nozzle 806 to swing around the positioning rod 807, so that the nozzle 806 blows the impurities and dust attached to the outside of the display screen 2 from different directions, blows away the impurities and dust attached to the display screen 2 that are not easy to fall off, improves the cleaning effect of the dust and impurities on the outside of the display screen 2, and ensures the clarity of the demonstration content of the demonstration platform.

[0063] Example 6: Reference Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.15 , an isotope tracing detection device, based on Example 5, further, the dehumidification box 5 is rotatably connected to the demonstration table 1 through a pin shaft, the inner wall of the dehumidification box 5 is fixedly provided with partitions 501 evenly distributed in a circumference, the outer side of the dehumidification box 5 is fixedly provided with a gear ring 502, and the sleeve 602 is provided with a rack 6021 meshing with the gear ring 502.

[0064] Specifically, when the lifting mechanism drives the display screen 2 to perform lifting and lowering movements, the rack 6021 on the sleeve 602 meshes with the gear ring 502 on the outside of the dehumidification box 5, so that the gear ring 502 drives the dehumidification box 5 to rotate, and the partition 501 in the dehumidification box 5 drives the desiccant inside to flip and roll, so that the desiccant particles in the dehumidification box 5 can fully contact with the air to absorb moisture, thereby preventing the desiccant from being statically accumulated and unable to effectively contact with the air, affecting the drying effect on the inside of the demonstration table 1, and preventing the display screen 2 from being damaged by moisture. It should be noted that the dehumidification box 5 adopts a mesh structure, which is convenient for the desiccant inside the dehumidification box 5 to contact with the air inside the demonstration table 1.

[0065] Working principle: When the display screen 2 is idle, it is placed in the demonstration table 1, and the top opening of the demonstration table 1 is covered by the top plate 3 to cover and protect the display screen 2, reduce dust or other stains on the display screen 2, so that the top of the demonstration table 1 can be used for other purposes, and the resources of the demonstration table 1 are reasonably utilized;

[0066] Before the display screen 2 is used, the lifting motor 6 is controlled to operate, and the output end of the lifting motor 6 drives the screw rod 601 to rotate in the demonstration platform 1, and the sleeve 602 outside the screw rod 601 moves along the axial direction of the screw rod 601 and drives the display screen 2 to move upward through the lifting plate 603;

[0067] When the screw rod 601 rotates, the main bevel gear 6011 meshes with the secondary bevel gear 703 on the rotating rod 7 for transmission, and the secondary bevel gear 703 drives the rotating rod 7 to rotate, and the reel 701 on the outer side of the rotating rod 7 reels the pull rope 702, and the pull rope 702 applies a force to the end of the top plate 3. When the top plate 3 is pulled by the pull rope 702 and the other end of the top plate 3 is lifted up by the upwardly moved display screen 2, the top plate 3 rotates around the fixed rod 401 as the center, and as the pull rope 702 is reeled up, the top plate 3 gradually moves into the accommodating groove 4;

[0068] When the top plate 3 moves downward in the receiving groove 4, the piston 801 is driven to move downward in the sleeve 8 through the connecting rod 802. During this process, the rod cavity of the sleeve 8 draws air outside the demonstration platform 1 through the intake valve 803.

[0069] After the display screen 2 is moved out of the demonstration platform 1, the staff can display the content of the meeting through the display screen 2. After the meeting, the lifting motor 6 drives the screw rod 601 to reverse, the sleeve 602 moves downward along the axis of the screw rod 601 and drives the display screen 2 to move into the demonstration platform 1 through the lifting plate 603, and the pull rope 702 on the reel 701 no longer applies force to the top plate 3, and the compressed second elastic element 12 in the sleeve 8 pushes the top plate 3 to move upward through the connecting rod 802. As the display screen 2 is stored in the demonstration platform 1, the top plate 3 moves out of the receiving groove 4, and a counterweight block 303 is provided at the end of the top plate 3 so that the top plate 3 automatically falls after moving out of the receiving groove 4, and shields and protects the display screen 2 placed in the demonstration platform 1;

[0070] When the top plate 3 moves upward in the receiving groove 4, the connecting rod 802 drives the piston 801 to move upward in the sleeve 8, and the piston 801 squeezes the air in the rod cavity of the sleeve 8. The air in the rod cavity of the sleeve 8 is discharged to each branch air pipe 8051 through the air outlet pipe 805, and blows the outer side of the display screen 2 gradually moving into the demonstration platform 1 through the nozzle 806 at the end of the branch air pipe 8051, so that the impurities and dust attached to the outer side of the display screen 2 are blown away when the display screen 2 is used;

[0071] When the screw rod 601 rotates, the active bevel gear 6012 on the outside is meshed with the driven bevel gear 901 on the rotating shaft 9 for transmission, and the driven bevel gear 901 drives the rotating shaft 9 and the cam 902 to rotate. When the cam 902 abuts against the force plate 1001 in the slide groove 10, it is pushed, and the first elastic element 1002 is deformed. When the cam 902 no longer abuts against the force plate 1001, the force plate 1001 is reset under the action of the first elastic element 1002, so that the force plate 1001 drives the moving plate 11 to reciprocate on the top of the demonstration platform 1. When the moving plate 11 moves, the connecting rod 111 drives the nozzle 806 to swing around the positioning rod 807, so that the nozzle 806 blows the impurities and dust attached to the outside of the display screen 2 from different directions, and blows away the impurities and dust attached to the display screen 2 that are not easy to fall off.
