The air dried by the dehumidifying ball inside the bulb 800 passes through the through holes in the wall of the bulb 800 to reach the dehumidifying chamber, then flows out of the connection pipe 704 into the return air chamber, and then returns to the lower installation chamber through the return air pipe 601.
In this embodiment, as shown in fig. 2,3 and 7, a plurality of air return pipes 601 are provided, the plurality of air return pipes 601 are uniformly distributed on the periphery of the air suction pipe 701 along the circumferential direction of the air suction pipe 701, and the dry air reaching the air return chamber is distributed and sent to different positions of the lower mounting chamber through the plurality of air return pipes 601; to complete the dehumidification of the humid air in the lower mounting chamber.
In this embodiment, as shown in fig. 1, the solar panel 200 is further included, and the solar panel 200 is disposed above the electric control cabinet 300 to store electric energy.
In combination with the above embodiment, the use principle and working process of the present invention are as follows: when the humidity sensor detects that the humidity in the lower mounting cavity reaches a preset value, the suction pump is started, so that the humid air in the lower mounting cavity enters the suction pipe 701 and then is led to the plurality of sleeves 900 respectively.
When the flowing air flows through the innermost group of guide plates 130, most of the force of the air acting on the guide plates 130 causes the guide plates 130 to rotate around the axis of the connecting shaft 110, and the other small force causes the guide plates 130 to move outwards by a preset distance, but the length of the chute 901 is greater than that of the groove 902, so that the limit bump 132 is still positioned in the chute 901; when the guide plate 130 rotates around the axis of the connecting shaft 110, gas is guided to the gas transmission ring 904 by the guide plate 130, enters the stirring plate 903 through the gas transmission hole, flows into the spherical shell 800 through the hole on the stirring plate 903, and is dried by the dehumidifying ball inside the spherical shell 800;
The dried gas passes through holes on the wall of the spherical shell 800 to reach the dehumidifying chamber, and the dried gas can directly flow to the connecting pipe 704 from a gap between the spherical shell 800 and the dehumidifying station 702, so that the situation that the gas repeatedly passes through the condition of high air flow resistance is avoided, and then is sent to different positions of the lower mounting cavity in a dispersed manner through the plurality of air return pipes 601; to complete the dehumidification of the moist air in the lower mounting cavity; the guide plate 130 rotates around the axis of the sliding tube 120 and drives the corresponding sleeve 900 to synchronously rotate through the limiting lug 132; when the sleeve 900 rotates, the stirring plate 903 stirs the dehumidifying balls in the spherical shell 800, so that the dehumidifying balls in the spherical shell 800 are in uniform contact with humid air, and the dehumidifying balls are fully utilized.
In the process that the dehumidifying balls in the innermost spherical shell 800 are changed from the dry state to the wet state, the viscosity of the dehumidifying balls is gradually increased, the resistance to rotation of the stirring plate 903 is gradually increased, the corresponding rotation speed of the sleeve 900 is slowed down, the force for driving the deflector 130 to rotate around the axis of the sleeve 900 is gradually reduced, and the force for driving the deflector 130 to move outwards is increased; the limit bump 132 moves in the chute 901 toward the recess 902, since the chute 901 is provided long enough and under the action of the second spring 122, it is ensured that the limit bump 132 does not reach into the recess 902 during the dehumidification process.
When all the dehumidifying balls in the innermost spherical shell 800 are in a wet state, the dehumidifying and drying operation cannot be performed on the gas, and at this time, the resistance to the stirring plate 903 is the greatest, and the sleeve 900 and the deflector 130 do not rotate around the axis of the sleeve 900 any more; at this time, the wind force acting on the deflector 130 cannot cause the deflector 130 to rotate, so all the wind force is used for moving the deflector 130 in a direction away from the axis of the air suction pipe 701, the movement of the deflector 130 drives the slide tube 120 to synchronously move through the connecting column 131, and at the same time, the limit bump 132 continues to move in the chute 901 towards the direction of the groove 902, and the second spring 122 stores the force; when the limit bump 132 slides into the groove 902, the trend of the compression spring to recover to be long is not hindered, and elastic potential energy is released; under the action of the compression spring, the guide plate 130 moves far away from the axis direction of the slide tube 120, and due to the fact that the connecting post 131 is in threaded fit with the slide tube 120, when the guide plate 130 moves far away from the axis direction of the slide tube 120, the convex post slides in the spiral groove 1311, the guide plate 130 rotates to be parallel to the axis of the slide tube 120, the guide assembly is in a retracted state, air is guided to move axially along the sleeve 900, and the guide assembly acts on the next guide mechanism from inside to outside.
The moist air flowing through the first group of guide plates 130 is not influenced any more, and flows directly to the next group of guide plates 130, so that the utilization rate of the dehumidifying balls is greatly increased, and the power of the air flowing is reasonably distributed on the corresponding guide plates 130, so that the sleeve 900 is ensured to have proper rotation power, the stirring effect of the stirring plate 903 is ensured, and the phenomenon that the wetted dehumidifying balls influence the air again can be avoided.
Repeating the above operation until all the dehumidifying balls in the spherical shell 800 are in a wet state, and cannot continuously dehumidify and dry the air, and at the moment, closing the suction pump, and not sucking air into the suction pipe 701; the electromagnetic valve 401 and the rotating motor are started, the rotating motor drives the air suction pipe 701 to rotate, when the air suction pipe 701 rotates, the unidirectional pipe 706 is opened, air in the upper mounting cavity enters the dehumidifying chamber through the unidirectional pipe 706, and the air passing through the heating assembly is changed into hot air; when the air suction pipe 701 rotates, the spherical shell 800 and the sleeve 900 synchronously move outwards under the action of centrifugal force; the annular friction plate 802 moves synchronously with the spherical shell 800, when the annular friction plate 802 moves to the drying station 703, the drying station 703 does not limit the rotation of the annular friction plate 802, and part of air heated by the heating component acts on the guide plate 803 to drive the spherical shell 800 to rotate; and the dehumidifying balls in the spherical shell 800 are dried, and since the spherical shell 800 is continuously rotated, moisture of the dehumidifying balls is gathered outside the spherical shell 800 under the centrifugal effect, so that the dehumidifying balls in the spherical shell 800 can be sufficiently dried. After the desiccant beads are dried by the air, the air passes through the desiccant exhaust pipe 705 and the main exhaust pipe 400 in this order, and is discharged from the exhaust port to the atmosphere.
During the synchronous outward movement of the spherical shell 800, the sleeve 900 and the slide 120, the first spring 801 and the second spring 122 store the force, the slide 120 is firstly contacted with the protrusion 111, and the slide 120 and the deflector 130 stop moving; the spherical shell 800 continues to be far away from the air suction pipe 701 under the action of centrifugal force, and the sleeve 900 synchronously moves outwards along with the spherical shell 800 while the spherical shell 800 moves, and because the outer end of the sliding pipe 120 is abutted with the bulge 111 at this time and cannot continue to move outwards, the air conveying ring 904 moves outwards relative to the sliding pipe 120, namely the air conveying ring 904 moves outwards relative to the guide plate 130; so the limit bump 132 is separated from the groove 902, and moves into the groove 901 after passing through the connection position of the smooth groove 901 and the groove 902; because the distance between the sliding groove 901 and the axis of the sliding tube 120 is smaller than the distance between the groove 902 and the axis of the sliding tube 120, the baffle 130 moves toward the axis direction of the sliding tube 120 as a whole to compress the compression spring at the moment when the limit bump 132 enters the sliding groove 901; since the connecting post 131 is screw-fitted with the slide tube 120, the boss slides in the spiral groove 1311 while the baffle 130 approaches the axis of the slide tube 120; the deflector 130 rotates, and the guide assembly resumes the deployed state; when all the dehumidifying balls in the ball shells 800 are dried, the rotating motor is turned off, and the air suction pipe 701 is not driven to rotate any more; the centrifugal force of the ball housing 800 and the sleeve 900 gradually disappears, the first spring 801 and the second spring 122 release elastic potential energy, and the slide 120 and the sleeve 900 are restored to the original positions by the first spring 801 and the second spring 122.
