Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a library bookshelf cleaning device. Background Art

[0002] The library is a public area for collecting, organizing and storing books and materials for people to read and refer to. The structure of the bookshelves in the library is basically to set multiple partitions in the vertical direction to form a multi-layer frame structure for placing books. In order to facilitate people to read books, the book placement space on the bookshelf is generally open, so it is easy for dust and other impurities to accumulate on the books. If the dust on the books is not cleaned in time, it will cause many damages to the books. For example, solid particles in the dust, especially those with edges and corners, will cause wear and tear on the paper of the book. The long-term accumulation of dust may cause the paper to stick together to form the so-called "archival bricks", which not only affects the reading of books, but also may permanently damage the structure of the book; the acid and alkaline components adsorbed by dust or contained in the dust itself will accelerate the aging process of the book paper, causing the paper to become brittle and the handwriting to fade, thereby shortening the service life of the book; dust is a medium for the spread of mold spores. In a humid environment, books are more susceptible to microbial invasion, leading to mold and decay, which not only affects the preservation of books, but also may pose a threat to the health of readers. In addition, dust may contain inhalable particles. If these particles are not cleaned up in time and enter the human respiratory tract during reading, they may cause a series of health problems. For example, long-term inhalation of large amounts of dust may lead to lung diseases. Therefore, it is very necessary to clean and maintain bookshelves regularly.

[0003] The core components of the existing bookshelf cleaning devices are mainly the use of brush cleaning and vacuuming equipment to clean the dust on the surface of books, which is more efficient and convenient than traditional manual cleaning. However, in fact, the books on the bookshelf are not always tightly placed together. In the process of people taking them, there will always be some books that are loose, causing some books to be placed at an angle, and the tilted books will form gaps with adjacent books or bookshelves. Even the gaps between some loose books are prone to dust accumulation. In the process of using brushes to clean the surface of books and bookshelves, not only can the dust in these gaps not be completely cleaned out, but also some dust will float into the gaps between books or books and bookshelves, resulting in a blind spot for cleaning. For example, the Chinese patent with publication number CN115716058A provides a multi-purpose bookshelf cleaning device for a library, in which a cleaning mechanism is fixed on the top of the inner side of the bookshelf gap, a sliding groove is opened at the bottom of the cleaning mechanism, and a threaded rod and a sliding block are installed on the inner side, and the connecting bin is driven to move by a motor, and then the brush bristles can be driven by the cleaning cover to move the bookshelf, the surface of the books and the top of the books to provide an effective dust sweeping effect, and at the same time, the dust suction fan blades on the inside of the vacuum cleaner can generate suction to suck the dust from the position of the dust suction groove, which is conducive to improving the dust cleaning effect on the surface of the books, but in the area where the books are placed loosely, the brush and the vacuum cleaner only have a better cleaning effect on the dust on the surface of the books, and the books and The dust in the gaps between books or between books and bookshelves, and in the gaps between some loose books and books cannot be completely cleaned out; for another example, the publication number CN221750293U provides a library bookshelf cleaning device, which uses a vehicle body to drive the first cleaning component and the second cleaning component to move, the first cleaning component can clean the dust on the side of the bookshelf, and the first cleaning roller drives a plurality of first brushes to rotate, and the plurality of first brushes can clean the dust on the side of the bookshelf and bring the dust into the first shell, the second cleaning component can clean the dust on the top of the bookshelf, and the second cleaning roller drives a plurality of second brushes to rotate, and the plurality of second brushes can clean the dust on the top of the bookshelf and bring the dust into the second shell. This device is the same as the above-mentioned patent with publication number CN115716058A. During the cleaning process, it can better clean the dust on the side and top surfaces of books, but it is difficult to thoroughly clean the dust accumulated inside the gaps between books or between books and bookshelves, and between loose books. In addition, in the above-mentioned two disclosed devices, during the dust cleaning process, the brush will cause the dust to float secondary, and the vacuum cleaner cannot completely absorb the floating dust in the first time, and some dust will still accumulate in the gap again.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The core components of the existing bookshelf cleaning devices are mainly the use of brush cleaning and vacuuming equipment to clean the dust on the surface of books, which is more efficient and convenient than traditional manual cleaning. However, in fact, the books on the bookshelf are not always tightly placed together. In the process of people taking them, there will always be some books that are loose, causing some books to be placed at an angle, and the tilted books will form gaps with adjacent books or bookshelves, and even the gaps between some loose books and books are prone to dust accumulation. In the process of using bristles to clean the surface of books and bookshelves, not only can the dust in these gaps not be completely cleaned out, but also some dust will float into the gaps between books or books and bookshelves for a second time, resulting in a blind spot for cleaning.

[0046] See also Figures 1 to 8As shown, in order to clean the dust in the bookshelf more thoroughly, especially in the area where books are loosely placed, in order to thoroughly clean the dust in the gaps between adjacent books or between books and bookshelves, and even in the gaps between some loose books and books, so as to keep the bookshelves and books clean and tidy, the present embodiment provides a library bookshelf cleaning device, including a mobile rack and a dust removal unit arranged on the mobile rack.

[0047] See also Figure 1 , Figure 2 and Figure 8 As shown, the mobile rack mainly includes a bottom collection box 51 and a lifting mechanism. The bottom of the collection box 51 is provided with a universal wheel 52. The lifting mechanism includes a guide rail 53 vertically fixed to one side of the collection box 51. The lower end of the guide rail 53 is lower than the body of the collection box 51. A stud 54 is rotatably connected in the guide rail 53. One end of the stud 54 is fixed to the output shaft of the second motor 55. The second motor 55 is fixed to the guide rail 53. Then, a lifting block 56 is connected to the slideway in the guide rail 53. The lifting block 56 is sleeved on the stud 54 and the two are threadedly connected. Then, the dust removal unit is installed on the lifting block 56, so that the dust removal unit can reach different bookshelf layers.

[0048] See also Figures 1 to 4 As shown, the dust removal unit is composed of a sealing module, a book shifting module and a dust suction module. The sealing module includes a dust hood 1 and a sealing assembly 2. The dust hood 1 has a rectangular opening for adapting to the width of adjacent partitions on the bookshelf, and the dust hood 1 is fixed on the lifting block 56. The sealing assembly 2 is arranged on the peripheral side of the opening of the dust hood 1, and is used to keep the gap formed between the edge of the dust hood 1 and the partition of the bookshelf sealed during the movement of the dust hood 1; the book shifting module includes a plurality of paddles 3 and a reciprocating assembly 4, and the plurality of paddles 3 are evenly arranged along the length direction of the dust hood 1. One end of the paddle 3 is inserted into the dust hood 1 and is rotatably connected to the side wall of the dust hood 1, and the other end is fixedly connected to a soft shifting block 31. The soft shifting block 31 is made of rubber or silicone, and the soft shifting block 31 is moved from the opening of the dust hood 1. The reciprocating assembly 4 is arranged on one side of the dust hood 1, and the ends of the plurality of paddles 3 away from the opening of the dust hood 1 are connected to the output end of the reciprocating assembly 4, and the reciprocating assembly 4 is used to drive the paddles 3 to swing; the dust suction module includes a first dust suction pump 5 and a dust suction plate 6, the dust suction plate 6 is a cavity structure and is fixedly mounted on the side wall of the dust hood 1 away from the opening, and the dust suction plate 6 is evenly provided with a plurality of dust suction holes 7 on the side wall facing the opening of the dust hood 1, and the suction port of the first dust suction pump 5 is connected to the cavity of the dust suction plate 6. The discharge port of the first dust suction pump 5 is connected to the collection box 51.

[0049] When cleaning the bookshelf, the universal wheel 52 at the bottom of the collection box 51 is used to push the entire device to one side of the bookshelf, and the second motor 55 is started to drive the stud 54 to rotate. Under the threaded transmission action of the stud 54 and the lifting block 56, the lifting block 56 brings the dust removal unit to the corresponding bookshelf layer. At this time, the collection box 51 is moved again so that the upper and lower side walls of the opening of the dust cover 1 are abutted against the upper and lower partitions adjacent to the corresponding bookshelf layer through the sealing component 2, and are completely fitted, so that the book placement area between the two partitions forms a relatively direct connection with the cavity of the dust cover 1, and then the reciprocating component 4 is started to drive the multiple paddles 3 to swing back and forth. The paddles 3 can realize the tossing of the books during the swinging process. In the area where books are placed tightly, the soft contact between the paddle 3 and the books through the soft paddle block 31 will directly deform and pass over the books. For the area where books are placed loosely, the books will swing left and right under the swinging action of the paddle 3, completely exposing the gaps between books or between books and bookshelves, and at the same time, the dust between the books will be shaken off. At the same time, the first vacuum pump 5 is used to provide negative pressure adsorption to the adsorption plate, so that the multiple adsorption holes on the adsorption plate can fully absorb the dust in the gaps between books or between books and bookshelves during the swinging of the books, so that the dust in the bookshelf is cleaned more thoroughly and the books are cleaner and tidier. In addition, during the vacuuming process, the staff can push the mobile rack with the dust removal unit to move along the length direction of the corresponding bookshelf layer, and the dust inside the bookshelf can be easily cleaned in the above manner during the movement.

[0050] See also Figure 3 and Figure 4As shown, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, the dust hood 1 is further optimized, and the optimized dust hood 1 includes a fixed shell 11, an adjustment block 12 and an adjustment component 13. The fixed shell 11 is a rectangular cavity structure and is fixed on the lifting block 56. The dust collecting plate 6 is installed on an inner wall of the fixed shell 11. The side of the fixed shell 11 opposite to the dust collecting plate 6 and the top are both opened, and then the adjustment block 12 is inserted from the opening at the top of the fixed shell 11. Through the setting of the adjustment block 12, the fixed shell 11 only retains the opening opposite to the dust collecting plate 6, and the two side walls opposite to the fixed shell 11 and the inner wall of the dust collecting plate 6 of the adjustment block 12 fit tightly to ensure the top of the fixed shell 11 is sealed, and then the adjustment component 13 is set between the adjustment block 12 and the outer wall of the fixed shell 11, which is used to adjust the insertion depth of the adjustment block 12 in the fixed shell 11 to adapt to the width of two adjacent partitions of the bookshelf. Preferably, in order to achieve the movement and adjustment of the adjustment block 12, the adjustment assembly 13 includes two support plates 131, which are respectively arranged on both sides of the adjustment block 12, and the support plates 131 are slidably connected to the outer wall of the fixed shell 11, and the upper end thereof is fixedly connected to the top of the adjustment block 12. A fastening bolt 132 is screwed on the support plate 131, and the fastening bolt 132 is rotated to tighten against the side wall of the fixed shell 11 to achieve the position fixation of the adjustment block 12. Then, the sealing assembly 2 is arranged on the side of the fixed shell 11 and the adjustment block 12 away from the dust collecting plate 6, and the paddle 3 is arranged at the bottom of the adjustment block 12.

[0051] When cleaning the bookshelf, loosen the fastening bolt 132 so that the adjustment block 12 is in a state where it can be freely adjusted up and down. At this time, the insertion depth of the adjustment block 12 in the fixed shell 11 is adjusted according to the width of the two adjacent partitions on the upper and lower sides of the bookshelf, so that the spacing between the bottom of the adjustment block 12 and the bottom wall of the fixed shell 11 adapts to the width of the two partitions, and then tighten the fastening bolt 132. The adjustment of the adjustment block 12 can ensure that the opening on the opposite side of the dust collecting plate 6 better matches the width of the upper and lower partitions of the bookshelf, so that the dust collecting plate 6 can absorb the dust on the books and bookshelf more concentratedly, and the floating dust can be blocked in the dust hood 1 area during the process of the paddle 3 moving the books, so that the dust is fully adsorbed and cleaned, and the cleaning of the books and bookshelf is more thorough. At the same time, by using the telescopic adjustment of the adjustment block 12, the opening of the dust collecting hood 1 relative to the adsorption plate can adapt to the width of the adjacent partitions on different bookshelves, and the versatility is wider.

[0052] Furthermore, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, each suction hole 7 on the suction plate 6 is connected to a hose, and multiple hoses are arranged in the cavity of the suction plate 6, and then all the hoses are gathered together at one end of the suction hole 7 and connected to the first suction pump 5 through a main pipe (not shown in the drawings). Thus, the negative pressure adsorption force provided by the first suction pump 5 can be more evenly distributed at the position of each suction hole 7, so that the adsorption can be better and more even during the suction process, so that the dust at each adsorption position can be cleaned more thoroughly.

[0053] See also Figure 3 , Figure 4 and Figure 8 As shown, further, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, a preferred sealing assembly 2 includes a first sealing plate 21, a second sealing plate 26, a movable sleeve 22, and a movable block 24. The first sealing plate 21 is arranged on the opening edge of the fixed shell 11 opposite to the dust collecting plate 6; the movable sleeve 22 is sleeved on the outside of the fixed shell 11, one end of which is fixedly connected to the first sealing plate 21, and the other end is connected to the fixed shell 11 through a first elastic member 23; the movable block 24 is inserted on the side wall of the adjustment block 12 away from the dust collecting plate 6, and the width of the movable block 24 is consistent with that of the adjustment block 12. The adjustment block 12 is provided with a groove for inserting the movable block 24, and the movable block 24 is connected to the adjustment block 12 through a second elastic member 25; the second sealing plate 26 is fixedly connected to the movable block 24, and is spliced ​​with the first sealing plate 21 through the second sealing plate 26 to surround the opening circumference of the fixed shell 11 away from the dust collecting plate 6. The first sealing plate 21 and the second sealing plate 26 can both be made of rubber pads, silicone pads or other elastic materials with good sealing performance. The first elastic member 23 and the second elastic member 25 are preferably compressed springs.

[0054] When cleaning the bookshelf, the first sealing plate 21 and the second sealing plate 26 are fitted with the two adjacent partitions above and below the bookshelf under the push of the movable rack, and the first elastic member 23 and the second elastic member 25 keep the first sealing plate 21 and the second sealing plate 26 in full and tight contact. At the same time, when the movable rack moves along the length direction of the bookshelf, the first elastic member 23 and the movable sleeve 22, the second elastic member 25 and the movable block 24 cooperate to compensate for the uneven distance between the fixed shell 11 and the bookshelf during the moving process, so that the first sealing plate 21 and the second sealing plate 26 can maintain abutment with the corresponding side plates, so that the dust collecting hood 1 and the corresponding bookshelf layer maintain a good connection state, so that the dust collecting plate 6 can absorb the dust in the bookshelf more thoroughly during adsorption.

[0055] See also Figure 3 and Figure 5As shown, further, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, the reciprocating assembly 4 includes a movable rod 41, a third elastic member 43, an eccentric wheel 44 and a first motor 45. The movable rod 41 is arranged horizontally, one end of which passes through the fixed shell 11 and is hinged to one end of each paddle 3 close to the dust collecting plate 6, and the other end is located outside the fixed shell 11 and is fixedly connected to the limiting plate 42. A third elastic member 43 is arranged between the limiting plate 42 and the side wall of the fixed shell 11. The third elastic member 43 is the same as the first elastic member 23 and the second elastic member 25. The preferred third elastic member 43 is preferably a compression spring, which is sleeved on the movable rod 41. One end of the compression spring is fixedly connected to the fixed shell 11, and the other end abuts against the limiting plate 42, so that the eccentric wheel 44 is rotatably connected to the fixed shell 11 through the rotating shaft, and the circumferential side wall of the eccentric wheel 44 abuts against the limiting plate 42. The end of the rotating shaft away from the fixed shell 11 is coaxially fixed with the output shaft of the first motor 45, and the first motor 45 is fixedly mounted on the fixed shell 11.

[0056] When cleaning the bookshelf, the first motor 45 is started to provide rotational power for the eccentric wheel 44. The eccentric wheel 44 will repeatedly push the limit block during rotation and, with the cooperation of the third elastic member 43, the movable rod 41 will form a state of linear reciprocating motion. In this way, the movable rod 41 will drive the paddle 3 to swing back and forth. The swinging frequency of the paddle 3 is regulated by setting the rotation speed of the first motor 45. During the swinging process of the paddle 3, the friction between the soft paddle block 31 and the books will cause the books on the bookshelf to be shaken left and right to a certain extent, so that the gaps between the books are exposed. At the same time, the shaking effect of the books can be used to shake off the dust mixed between the books, especially the dust between the loosely placed books can be more fully cleaned out, so that the dust can be fully and thoroughly cleaned under the adsorption effect of the dust suction plate 6.

[0057] See also Figure 6 As shown, further, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, a notch 8 is opened on one side of the eccentric wheel 44, and the minimum distance from the notch 8 to the rotating shaft is greater than the minimum distance from the rotating shaft to the circumference of the eccentric wheel 44. When in use, when the limit plate 42 reaches the position of the notch 8, it will rebound quickly under the action of the third elastic member 43, so that the movable rod 41 generates a sense of vibration, and then the movable rod 41 transmits the vibration effect to the book through the paddle 3, so that the book insertion swings instantly, so that the dust mixed between the books can be fully shaken off and sucked away by the dust suction plate 6, and the dust is cleaned more thoroughly.

[0058] See also Figure 3 and Figure 8As shown, further, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, the bottom of the adjustment block 12 located in the fixed shell 11 is evenly distributed with multiple dust collection cylinders 9 perpendicular to the dust collection plate 6, and the dust collection tube 10 is inserted at the end of the dust collection cylinder 9 away from the dust collection plate 6. The end of the dust collection tube 10 located in the dust collection cylinder 9 is open, and the end extending from the dust collection tube 10 is in a closed state, and multiple dust collection ports are opened along the axial direction on the side wall of the dust collection tube 10 away from the adjustment block 12, that is, the dust collection port is always downward, and a compression spring is provided between the end of the dust collection tube 10 facing the dust collection plate 6 and the dust collection tube 10, and a gas channel is opened in the adjustment block 12, and the gas channel is connected to the second dust collection pump, and the other end of the dust collection cylinder 9 is connected to the gas channel. Preferably, the discharge port of the second dust collection pump is connected to the collection box 51, and the collection box 51 can be opened to process the collected dust after the dust collection is completed.

[0059] When cleaning the bookshelf, the vacuum tube 10 is inserted into the bookshelf and is on the top of the books. The elastic action of the compression spring can make the vacuum tube 10 extend well into the bookshelf and use the depth of the bookshelf. At this time, the second vacuum pump is started to provide adsorption force to the vacuum tube 10, so that the dust on the top of the books can be adsorbed. At the same time, during the swinging of the books, the adsorption from the top of the books and the side adsorption of the adsorption plate are combined, so that the exposed books and the dust in the gaps between the books or the bookshelves can be more thoroughly adsorbed. In order to reduce the friction between the vacuum tube 10 and the inner wall of the bookshelf during the movement, the vacuum tube 10 is prevented from damaging the bookshelf and deforming itself, so as to achieve a better adsorption effect, a ball 33 is rotatably connected to the end of the vacuum tube 10 away from the dust cylinder 9. The ball 33 is contacted and rolled with the inner wall of the bookshelf to ensure the stability of the vacuum tube 10 during movement.

[0060] See also Figure 7 As shown, further, in order to make the dust and other impurities inside the bookshelf clean more thoroughly, each pick 3 is equipped with a micro vibrator 32, such as a flat motor vibrator of model 1034, whose outer size is 10mm*3.4mm. During the cleaning process of the bookshelf, the vibration effect of the pick 3 is transmitted to the books, so that the dust mixed between the books and even the dust accumulated between the pages inside the books can be shaken out better, so that the dust on the books can be cleaned more thoroughly and cleanly.

[0061] Furthermore, the device is also provided with an ultraviolet sterilization component (not shown in the drawings), including a power supply device and a plurality of ultraviolet sterilization lamps connected to the power supply device. The ultraviolet sterilization lamps are arranged on one side of the dust suction plate 6 having the dust suction hole 7. During the dust suction process, the ultraviolet sterilization lamps can irradiate the surface of the book, kill bacteria on the surface of the book, and extend the shelf life of the book.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
