Different from the way of fixing the textile in the embodiment, the function of fixing the textile can also be realized through the magnet adsorption.
The working principle is as follows:
the rainwater simulation module works: during the experiment, fix the fabrics sample on placing board 18 through fixing device 42, shower nozzle 2 begins to spray water downwards, spun water can permeate the fabrics sample and flow into in the water bucket 21 through water inlet 23 and be collected by water bucket 21, motor 27 drives the ring gear 3 through the output shaft and rotates, the rotation of ring gear 3 can be the hole of draining of intermittent type formula with shower nozzle 2 through the crisscross part of its inboard and plug up, thereby constantly break the water column of shower nozzle 2 and thereby make shower nozzle 2 drain the continuous formation water droplet of the water that the hole was emitted, thereby the state of the raindrop of simulation rainwater.
The work of the blowing module: the rotation of the toothed ring 3 drives the gear I5 to rotate, the rotation of the gear I5 drives the frustum 7 to rotate, the rotation of the frustum 7 drives the roller 30 to rotate, the rotation of the roller 30 drives the rotating shaft I34 to rotate, the rotation of the rotating shaft I34 drives the fan blade 22 to rotate through the transmission of the bevel gear 37, so as to test the function of blowing, meanwhile, the rotation of the toothed ring 3 also drives the shifting block 4 to rotate, when the shifting block 4 rotates to the position of the sliding rod I8, the sliding rod I8 is pushed to slide towards one end close to the cylinder 10, the sliding rod I8 drives the rocker I13 to move towards the cylinder 10, so as to drive the rocker II 26, the cylinder 10 to rotate, when the shifting block 4 rotates to pass through the sliding rod I8, under the reset action of the spring I9, the sliding rod I8 is pushed to return to the original position, and the sliding rod I8 continuously drives the rocker I13 to drive the rocker II 26 to move, thereby drive drum 10 and rotate a complete circumference, the rotation of drum 10 can promote the motion of guide rail post 41 through guide rail groove 25, owing to there is the limiting displacement of link 24, the rotation of drum 10 can drive litter second 28 and make a round trip in the reciprocal slip of upper and lower on the outer wall of drum 10, thereby drive gyro wheel 30 and make a round trip to slide once up and down on the surface of frustum 7, because frustum 7 is the toper, from the top down cross sectional area reduces gradually, thereby the instantaneous linear velocity when contacting with gyro wheel 30 increases gradually and reduces again, thereby make gyro wheel 30 pivoted speed increase gradually and reduce again gradually, until next shifting block 4 again with litter first 8 contacts. Because the sliding column 29 is connected with the sliding rod II 28 in a sliding manner, the roller 30 can be continuously attached to the surface of the frustum 7 through the elastic force of the spring II 40, and along with the up-and-down movement of the roller 30, the sliding column 29 can slide on the sliding rod II 28 in a reciprocating manner once from left to right, so that the rotation of the frustum 7 can continuously drive the rotating shaft I34 to rotate to drive the fan blades 22 to rotate. In addition, when the sliding column 29 slides back and forth on the second sliding rod 28 once from left to right, the first movable rotating shaft 34 is driven to move simultaneously, so that the fan blade 22 is driven to move simultaneously, and due to the existence of the second supporting rod 33, the third rocker 35 is driven to drive the first rotating shaft 34 of the fan blade 22 to rotate as the center of a circle, so that the fan blade 22 swings to blow, the whole module is realized, the wind speed is increased and then reduced, and the swinging blowing is realized, so that the effect of real natural blowing is simulated.
The angle adjustment work: when the second slide rod 28 slides up and down, the toggle frame 11 is driven to move up and down simultaneously once, because the lower end of the toggle frame 11 is provided with the inclined block 36, when the inclined block 36 moves downwards, the inclined block 36 at the upper end can push the convex block 32 to drive the circular ring 15 to rotate by an interval angle between the convex blocks 32, when the inclined block 36 moves upwards, the inclined block 36 at the lower end can simultaneously drive the circular ring 15 to rotate by an interval angle between the convex blocks 32, the rotation of the circular ring 15 can drive the first rotating rod 16 to rotate by the same angle, the rotation of the first rotating rod 16 can drive the placing plate 18 to simultaneously rotate by the same angle, therefore, the function of adjusting the angle of the placing plate 18 is realized, when the placing plate 18 rotates, the gear wheel 44 is driven to rotate through the gear wheel 43, and the gear wheel 44 drives the rotating rod 19 to rotate through the gear wheel 43 of the rotating rod 19 to drive the water wheel 20 to rotate, so that the water wheel is switched to the next water bucket 21. Every will all drive waterwheel 20 along with place board 18 and rotate an angle simultaneously to switch next bucket 21 and carry out the water receiving, can just judge the condition that this fabrics water of different health positions permeates under the environment of natural rain according to the weight of the water in every bucket 21.
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.
