The groove 401, the third spring 402, the first moving block 403 and the hemispherical bump 404 constitute a buffer mechanism 40.
The working principle is as follows: because the spring is fixedly arranged at the left side inside the first concave shell 10, one end of the spring, which is far away from the first concave shell 10, is fixed at the right side of the first moving plate 11, the spring is fixedly arranged at the right side inside the second concave shell 15, and one end of the spring, which is far away from the second concave shell 15, is fixed at the right side of the second moving plate 16, the first scraper 13 and the second scraper 18 are always close to the inner wall of the vacuum tube.
Because the right end of the first permanent magnet 24 is an N pole, and the left end of the second permanent magnet 34 is an S pole, when the device is not started, the first permanent magnet 24 is attracted by the second permanent magnet 34 and the elastic force of the first spring 28, the elastic force is greater than the attraction force, the first permanent magnet 24 drives the switch knob 26 through the second moving rod 25, the switch knob 26 is located at the left end of the switch chute 27, the circuit of the first motor 6 is disconnected, and the first motor 6 does not rotate.
When the single-pole double-throw switch works, the single-pole double-throw switch 32 is firstly opened to the upper end, the linear motor 31 drives the output moving block 33 to move downwards, the output moving block 33 drives the second spring 35 to move downwards, the second spring 35 drives the third moving plate 36 to move downwards, and the third moving plate 36 drives the second permanent magnet 34 to move downwards. When the second permanent magnet 34 moves for a certain distance, the attractive force applied to the first permanent magnet 24 is greater than the elastic force of the first spring 28, the first permanent magnet 24 moves to the right, and the first permanent magnet 24 drives the switch knob 26 to move to the right through the second moving rod 25, so that the circuit of the first motor 6 is switched on. The first motor 6 rotates, the first motor 6 drives the rotating shaft 8 to rotate through the output shaft 7, the rotating shaft 8 drives the first concave shell 10 through the first connecting rod 9, and the first concave shell 10 drives the first scraper 13 to rotate through the first moving plate 11 and the second connecting rod 12, so that scales are cleared. The rotating shaft 8 drives the second concave shell 15 through the third connecting rod 14, and the second concave shell 15 drives the second scraper 18 to rotate through the second moving plate 16 and the fourth connecting rod 17, so that scale is cleaned.
When the second permanent magnet 34 moves downwards, the first permanent magnet 24 is attracted by the second permanent magnet 34 to move downwards, and because the bottom of the first permanent magnet 24 is slidably mounted on the inner bottom wall of the first housing 5, the first permanent magnet 24 drives the first housing 5 to move downwards, the first housing 5 drives the first motor 6 to move downwards, the first motor 6 drives the rotating shaft 8 to move downwards through the output shaft 7, the rotating shaft 8 drives the first concave housing 10 to move downwards through the first connecting rod 9, the first concave housing 10 drives the first scraper 13 to move downwards through the first moving plate 11 and the second connecting rod 12, meanwhile, the rotating shaft 8 drives the second concave housing 15 to move downwards through the third connecting rod 14, and the second concave housing 15 drives the second scraper 18 to move downwards through the second moving plate 16 and the fourth connecting rod 17. The speed and distance of the downward movement of the first squeegee 13 and the second squeegee 18 coincide with the speed and distance of the downward movement of the second permanent magnet 34.
Since not less than five buffer mechanisms 40 are equidistantly distributed on the left side inside the third housing 29, and the left side of the third moving plate 36 is slidably mounted on the left side inside the third housing 29, the downward movement of the third moving plate 36 is stopped first by the buffer mechanisms 40 when moving downward. At the same time, the second permanent magnet 34 drives the first scraper 13 and the second scraper 18 to stop moving downwards, but the first scraper 13 and the second scraper 18 still rotate, and scale is cleaned at the position. Since the third moving plate 36 stops moving downward, but the output moving block 33 still moves downward, the second spring 35 is compressed. When the second spring 35 is compressed to a certain degree, and the pushing force applied to the third moving plate 36 is greater than the resistance force, the third moving plate 36 then moves downward, so that the hemispherical bump 404 moves leftward, the first moving block 403 is driven to move leftward, the third spring 402 is compressed, and when the third moving plate 36 moves below the buffer mechanism 40, the buffer mechanism 40 is restored. Since the distance between the buffer mechanisms 40 is equal to the length of the first scraper 13, the third moving plate 36 performs descending-stopping-descending intermittent motion through the buffer mechanisms 40 arranged at equal intervals, so that each position of the inner wall of the inner glass tube 2 has a sufficient cleaning time, scale on the inner wall of the inner glass tube 2 is cleaned, and scale at certain positions is prevented from being left due to insufficient cleaning time.
When the first shell 5 moves downwards, the telescopic rod 4 is driven to extend, meanwhile, the first shell 5 drives the second shell 19 to descend and rotate through the output shaft 7, the second shell 19 drives the fifth connecting rod 21 and the sixth connecting rod 22 to descend and rotate through the first moving rod 20, and the fifth connecting rod 21 drives the semicircular scraper 23 to descend and rotate. Because the length of telescopic link 4 after the complete extension is greater than the length of interior glass pipe 2, linear electric motor 31's maximum stroke equals the distance of semi-circular scraper blade 23 least significant end to interior glass pipe 2 inner wall least significant end, and first carriage release lever 20 slidable mounting is in the inboard of second casing 19 simultaneously, so semi-circular scraper blade 23 can descend to least significant end and laminate interior glass pipe 2 least significant end inner wall and carry out work.
After the semicircular scraper 23 moves for a period of time, the single-pole double-throw switch 32 is turned on to the lower end, the linear motor 31 drives the output moving block 33 to move upwards, the output moving block 33 drives the third moving plate 36 to move upwards through the second spring 35, the third moving plate 36 drives the second permanent magnet 34 to ascend, the second permanent magnet 34 drives the first permanent magnet 24 to ascend through the attraction force of the magnet, the first permanent magnet 24 drives the first shell 5 to ascend, the first shell 5 drives the first motor 6 to move upwards, the first motor 6 drives the rotating shaft 8 to move upwards through the output shaft 7, the rotating shaft 8 drives the first concave shell 10 to move upwards through the first connecting rod 9, the first concave shell 10 drives the first scraper 13 to move upwards through the first connecting rod 11 and the second connecting rod 12, meanwhile, the rotating shaft 8 drives the second concave housing 15 to move upwards through the third connecting rod 14, and the second concave housing 15 drives the second scraper 18 to move upwards through the second moving plate 16 and the fourth connecting rod 17. Simultaneously first motor 6 passes through output shaft 7 and drives second casing 19 and rise, clears up for the second time, avoids there being the incrustation scale to remain, and second casing 19 drives semicircular scraper blade 23 through fifth connecting rod 21 and rises.
When the third moving plate 36 is lifted, the buffer mechanism 40 is used to perform the intermittent movement of lifting-stopping-lifting, so that the first scraper 13 and the second scraper 18 have enough cleaning time at each position.
When the output moving block 33 rises to a position before falling, the single-pole double-throw switch 32 is turned off, the output moving block 33 drives the second permanent magnet 34 to reset through the second spring 35 and the third moving plate 36, at the moment, the first permanent magnet 24 receives the attraction force of the second permanent magnet 34 and the elastic force of the first spring 28, the elastic force is larger than the attraction force, the first permanent magnet 24 drives the switch knob 26 to move leftwards through the second moving rod 25, the circuit of the first motor 6 is turned off, and the first motor 6 stops rotating.
In conclusion, the inner wall cleaning mechanism of the solar vacuum tube realizes descaling of the slender vacuum tube through the reciprocating motion of the linear motor 31, the attraction of the magnet and the extension of the telescopic rod 4, achieves the effects of preventing scale from accumulating on the inner wall of the solar vacuum tube, improving the solar utilization rate of the vacuum tube and prolonging the service life of the vacuum tube. Utilize buffer gear 40 and second spring 35, the intermittent type formula motion of second permanent magnet 34 has been realized, thereby it keeps rotatory to realize when the scraper blade descends, carry out intermittent type formula clearance, every position of 2 inner walls of glass pipe all has a section clearance time of sufficient length in making, ensure the incrustation scale clean up of 2 inner walls of glass pipe in will, reached and prevented that certain position from leaving the effect of water because of clearance time is not enough, reach the whole inner wall of glass pipe 2 of clearance simultaneously, it is more effective to make the scale removal. The effect that the scraper is always close to the inner wall of the vacuum tube is achieved by utilizing the sealing space between the movable plate and the concave shell. According to the inner wall cleaning mechanism of the solar vacuum tube, the balance between the attraction force of the first permanent magnet 24 and the second permanent magnet 34 and the elastic force of the second spring 35 is utilized to realize the combined control of the linear motor 31 and the first motor 6, so that the effect that the cleaning mechanism in the vacuum tube needs to be started again is avoided. Through the cooperation of second casing 19, first carriage bar 20 and semi-circular scraper 23, reached the effect of clearance vacuum tube semicircle bottom.
