similarly, when the weight block 6 moves upward, the two groups of holding plates 35 no longer hold the weight block 6 due to the elastic potential energy of the spring three 36, thereby ensuring the smooth rolling of the curtain 5.
The working principle of the first embodiment of the scheme is as follows: when the information technology teaching device based on big data is used, in the process of big data information technology teaching, when the curtain 5 is needed to be used for putting in teaching contents, the driving motor 2 is started, the driving motor 2 is controlled to rotate reversely so as to drive the winding roller 3 to rotate reversely, at the moment, the spring III 36 and the elastic pull rope 32 are in a stretching state, the counterweight block 6 starts to move downwards slowly due to the self gravity, the spring III 36 and the pull-down action of the elastic pull rope 32, simultaneously, the end, located at the back of the counterweight block 6, of the movable rod II 8 is driven to move downwards, simultaneously, the connecting end, connected with the movable rod II 7 and the movable rod II 8, of the movable rod II 8 is pulled to move downwards, at the moment, the movable rod II 8 and the movable rod II 7 gradually turn to a vertical stretching state from a folding state, the movable rod I7 and the movable rod II 8 are matched for use, the slowly unfolded curtain 5 can be limited, and the curtain 5 is prevented from shifting in the front and back direction or left and right direction due to outside influence in the unfolding process, the phenomenon of wrinkling on the surface of the curtain 5 is caused, and the flatness of the surface of the curtain 5 is improved;
when the counterweight block 6 moves to the upper part of the base 28, the third spring 36 and the elastic pull rope 32 are not in a stretching state at the moment;
after the curtain 5 is used, the curtain 5 needs to be rolled, and due to the fact that a large amount of dust exists in the teaching environment, dust can be accumulated on the surface of the curtain 5 if the curtain 5 is rolled directly without cleaning, and the next teaching effect is affected;
when the curtain 5 needs to be rolled, the driving motor 2 is started and controls the driving motor 2 to rotate forwards, so that the winding roller 3 is driven to rotate, the rotating disc 9 is driven to rotate through the rotation of the winding roller 3, and the sliding seat I10 and the limiting block 12 are driven to rotate;
the ratchet wheel disc 13 is shifted to rotate forwards through the limiting block 12, the ratchet wheel disc 13 is further driven to rotate forwards, the first gear 16 and the second gear 17 meshed with the first gear 16 are further driven to rotate synchronously, the third movable rod 18 located at the eccentric position of the first gear 16 and the second gear 17 is further driven to move periodically from top to bottom, the connecting plate 19 is further driven to move synchronously, when the connecting plate 19 moves downwards, the push rod 20 is pushed to move downwards synchronously, the piston plate 41 is further pushed to slide downwards on the inner wall of the atomizing housing 21, the pressure between the baffle plate 42 and the piston plate 41 is increased at the moment, and air between the piston plate 41 and the baffle plate 42 is compressed from the position of the second check valve 44 to enter the communicating pipe 40;
according to the venturi spraying principle, when air flows at a high speed on the inner wall of the communicating pipe 40, negative pressure is generated at the top end of the liquid pumping pipe 45, so that the cleaning liquid in the inner cavity of the atomizing housing 21 below the baffle 42 is pumped out upwards to drive the liquid or other fluids to be sprayed onto the obstacle together, the liquid drops are splashed to the periphery under the high-speed impact to be changed into mist-shaped particles to be sprayed out from the tail end of the communicating pipe 40, and the mist-shaped particles are sprayed onto the surface of the curtain 5 through the water spraying holes on the surface of the spraying plate 27, so that the function of automatically spraying the cleaning liquid is realized;
similarly, when the push rod 20 moves upwards, negative pressure is generated between the piston plate 41 and the baffle plate 42, so that outside air is sucked from the first one-way valve 43, and the automatic air supplementing function is realized;
meanwhile, when the connecting plate 19 moves up and down, the connecting rod 25 is driven to move up and down, the sliding plate 24 is driven to slide up and down on the inner wall of the sliding seat II 23, the cleaning roller 26 and the spraying plate 27 synchronously move up and down, the outer wall of the curtain 5 can be dynamically sprayed with disinfectant when the spraying plate 27 moves up and down, the surface of the curtain 5 can be dynamically wiped when the cleaning roller 26 moves up and down, the sprayed cleaning solution can be wiped, and the cleaning effect is improved;
will drive balancing weight 6 rebound when rolling curtain 5, and then tensile elasticity stay cord 32 and three 36 of spring, guarantee the vertical rebound of one end that elasticity stay cord 32 is close to balancing weight 6 through the guide effect of leading wheel 33.
The working principle of the second embodiment is as follows: when the counterweight block 6 moves downwards, the inclined rod 38 is driven to move downwards synchronously, when the inclined rod 38 gradually moves to the upper part of the base 28, the bottom end of the inclined rod 38 is inserted into the inner wall of the chute 39, and then certain extrusion force is generated on the chute 39, and then the two groups of sliding blocks 34 are driven to move oppositely on the inner wall of the chute 29, and then the third spring 36 is stretched, so that the two groups of clamping plates 35 are driven to clamp the outer wall of the counterweight block 6, and the curtain 5 is ensured not to shift under the influence of the outside after dropping, and the shadow watching effect is improved;
similarly, when the weight block 6 moves upward, the two groups of holding plates 35 no longer hold the weight block 6 due to the elastic potential energy of the spring three 36, thereby ensuring the smooth rolling of the curtain 5.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
