DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 12 The present invention provides a technical solution: a guide rail assembly for a hanging basket of a spent fuel container.

[0021] Embodiment 1, a guide rail assembly for a hanging basket of a spent fuel container, comprising: a slider 1 is movably provided on the outer surface of the guide rail 2, a hook 3 is fixed to the side surface of the slider 1, a spent fuel container body 4 is provided at the lower end of the hook 3, a protrusion 6 is fixed to the inner surface of the slider 1, a round groove 13 is provided inside the protrusion 6, a ball 7 is movably provided on the inner wall of the round groove 13, a laser sensor 9 is fixed to the side surface of the end of the protrusion 6, when dust adheres to the surface of the guide rail 2, the laser sensor 9 sends an electrical signal to the micro cylinder 22 because the surface of the guide rail 2 is uneven.

[0022] A cleaning rod 23 and a movable sleeve 24 are movably provided on the inner wall of the cleaning groove 16, and a first baffle 21 and a second baffle 25 are fixed to the outer surface of the movable sleeve 24. A scraper 8 is movably provided at the end of the first baffle 21, and a micro cylinder 22 is movably provided at the end of the second baffle 25. The output end of the micro cylinder 22 moves and supports the second baffle 25. The support of the second baffle 25 will drive the first baffle 21 to rotate counterclockwise through the movable sleeve 24. The rotation of the first baffle 21 will drive the scraper 8 to rotate. The scraper 8 will contact the surface of the guide rail 2 and scrape off the dust adhered to the surface of the guide rail 2 to prevent the dust from contacting the ball 7 and affecting the normal operation of the slider 1.

[0023] On the basis of embodiment 1, in order to clean the dust on the surface of the guide rail 2, a slide groove 5 is opened on the side surface of the guide rail 2, and the slide groove 5 corresponds to the protrusion 6 and is movably clamped. The cleaning groove 16 is opened on the side surface of the protrusion 6 on the side of the circular groove 13. A connecting groove 15 is opened on the inner wall surface of the circular groove 13. An inner groove 12 is opened on the inner wall of the connecting groove 15. The connecting groove 15 connects the inner groove 12 and the connecting groove 17. A support block 14 is fixed on the inner wall surface of the circular groove 13. The support block 14 ensures that the ball 7 will not be offset during rotation.

[0024] The ball 7 is movably arranged on the end surface of the support block 14. There are two groups of support blocks 14. The two groups of support blocks 14 are symmetrically distributed. The ball 7 is located between the two groups of support blocks 14. The distance between the two groups of support blocks 14 is greater than the radius of the ball 7 but smaller than the diameter of the ball 7. A connecting rod 11 is fixed to the outer surface of the ball 7, and a transmission gear 10 is fixed to the end of the connecting rod 11.

[0025] The connecting rod 11 corresponds to the connecting groove 15 and is movably clamped, the transmission gear 10 corresponds to the inner groove 12 and is movably clamped, the inner wall of the inner groove 12 is provided with a connecting groove 17, and a passive gear 18 is fixed to the end of the cleaning rod 23, and the passive gear 18 is movably clamped on the inner wall of the connecting groove 17. The transmission gear 10 corresponds to the passive gear 18 and is movably clamped. The rolling of the ball 7 will drive the passive gear 18 to rotate through the transmission gear 10, and the rotation of the passive gear 18 will drive the cleaning rod 23 to rotate. Since the scraper 8 is received in the cleaning groove 16, the end of the scraper 8 that scrapes off the dust has been flipped to the inside, that is, corresponding to the cleaning rod 23, so the rotating cleaning rod 23 will clean the end of the scraper 8 that has just scraped off the dust, thereby ensuring the cleanliness of the end of the scraper 8 and better cleaning the dust on the surface of the guide rail 2. The cleaning rod 23 is located inside the cleaning groove 16, and the first stopper 19 and the second stopper 20 are fixed to the side surface of the inner wall of the cleaning groove 16.

[0026] The length of the first baffle 19 and the second baffle 20 is less than half the length of the scraper 8. The first baffle 21 and the second baffle 25 are distributed in a circle with the axis of the movable sleeve 24 as the axis center. The angle between the first baffle 21 and the second baffle 25 is less than ninety degrees. One end of the micro cylinder 22 is fixed on the inner wall surface of the cleaning groove 16, and the output end of the micro cylinder 22 is movably arranged at the end of the second baffle 25. The length of the first baffle 21 is greater than the length of the second baffle 25. The output end of the micro cylinder 22 moves and supports the second baffle 25. The support of the second baffle 25 will drive the first baffle 21 to rotate counterclockwise through the movable sleeve 24. The rotation of the first baffle 21 will drive the scraper 8 to rotate. The scraper 8 will contact the surface of the guide rail 2 and scrape off the dust adhered to the surface of the guide rail 2 to prevent the dust from contacting the ball 7 and affecting the normal operation of the slider 1.

[0027] A fan-shaped groove 26 is provided on the bottom surface of the first baffle 21 where the scraper 8 is connected to the first baffle 21. The angle of the fan-shaped groove 26 is a flat angle. A limit block 27 is fixed to the end of the scraper 8. The fan-shaped groove 26 corresponds to the limit block 27 and is movably arranged. When the scraper 8 continues to be stored, it will be blocked by the first stop block 19. At this time, the end of the scraper 8 that has not scraped off the dust will be close to the first stop block 19, so that the end that has scraped off the dust will continue to flip over until it flips over to the limit block 27 located at the lower end inside the fan-shaped groove 26. The limit block 27 is blocked and cannot rotate at this time. Therefore, at this time, both ends of the scraper 8 are restricted by the first stop block 19 and the limit block 27 and cannot flip over.

[0028] In actual use, the hook 3 is hung on the spent fuel container body 4, and then the hook 3 is controlled to lift the spent fuel container body 4 upward, and the slider 1 is controlled to drive the spent fuel container body 4 to move to the transportation device. When dust adheres to the surface of the guide rail 2, the laser sensor 9 sends an electrical signal to the micro cylinder 22 because the surface of the guide rail 2 is uneven, and the output end of the micro cylinder 22 moves and supports the second baffle 25. The support of the second baffle 25 will drive the first baffle 21 to rotate counterclockwise through the movable sleeve 24. The rotation of the first baffle 21 will drive the scraper 8 to rotate, and the scraper 8 will contact the surface of the guide rail 2 and scrape off the dust adhered to the surface of the guide rail 2, so as to prevent the dust from contacting the ball 7 and affecting the normal operation of the slider 1; When there is no dust on the surface of the guide rail 2, the laser sensor 9 controls the output end of the micro cylinder 22 to retract, so the second baffle 25 will rotate clockwise, and at the same time, the first baffle 21 will be driven to rotate clockwise through the movable sleeve 24, so the scraper 8 will be stored in the cleaning groove 16. When the scraper 8 is stored in the cleaning groove 16, it will be blocked by the second block 20. Since the scraper 8 is movably arranged at the end of the first baffle 21, and the limit block 27 is located at the uppermost end of the fan-shaped groove 26 at this time, the scraper 8 will be turned over by the obstruction of the second block 20. Without being restricted by the cooperation between the fan-shaped groove 26 and the limit block 27, the scraper 8 turns over so that the end that just scraped the dust rotates upward. When the scraper 8 continues to be stored, it will be blocked by the first stopper 19. At this time, the end of the scraper 8 that has not scraped the dust will be close to the first stopper 19, so that the end that scraped the dust continues to turn over until it turns over to the limit block 27 located at the lower end of the fan-shaped groove 26. The limit block 27 is blocked and cannot rotate at this time. Therefore, at this time, both ends of the scraper 8 are restricted by the first stopper 19 and the limit block 27 and cannot turn over. At the same time, the output end of the micro cylinder 22 is no longer retracted; Since the ball 7 rolls on the inner wall of the slide groove 5, the rolling of the ball 7 drives the driven gear 18 to rotate through the transmission gear 10, and the rotation of the driven gear 18 drives the cleaning rod 23 to rotate. Since the scraper 8 is stored in the cleaning groove 16, the end of the scraper 8 that has scraped the dust has been turned inside, that is, corresponding to the cleaning rod 23, so the rotating cleaning rod 23 will clean the end of the scraper 8 that has just scraped the dust, thereby ensuring the cleanliness of the end of the scraper 8 and better cleaning the dust on the surface of the guide rail 2; When the scraper 8 is needed to clean the guide rail 2 again, the first baffle 21 drives the scraper 8 to rotate outward, and the scraper 8 will be blocked by the second baffle 20 and flipped, so that one end of the scraper 8 that has cleaned the dust will flip to the outside and will be blocked by the opening of the cleaning groove 16. At the same time, the limit block 27 will rotate to the uppermost end of the fan-shaped groove 26 due to the flipping of the scraper 8. Therefore, when the scraper 8 scrapes the dust on the surface of the guide rail 2, the scraper 8 will not continue to flip due to the reaction force of the dust.

[0029] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
