Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a constant humidity cultural relic preservation cabinet. Background Art

[0002] Cultural relic preservation has always been a key task in the field of cultural heritage protection. Whether it is museums, archives or individual collectors, they all need to effectively protect precious cultural heritage such as cultural relics and artworks. Maintaining appropriate humidity is a crucial step in the preservation process of cultural relics. Excessively high or low humidity can cause serious damage to cultural relics. Therefore, constant humidity cultural relic preservation cabinets have become very necessary equipment.

[0003] After searching, Chinese patent No. CN202120451263.X discloses a constant humidity cultural relic preservation cabinet, including a cabinet body, a humidity sensor is provided on the top of the cabinet inner cavity, and a constant humidity purification device is provided at the bottom of the cabinet inner cavity, a control panel electrically connected to the humidity sensor and the constant humidity purification device is fixedly provided on the outer side surface of the cabinet body, a plurality of grooves are equally spaced on the side wall of the cabinet inner cavity, a desiccant bag is provided in the groove, and a sealing plate is movably provided in the groove, a control mechanism for controlling the opening and closing of the groove is provided in the cabinet body, the control mechanism includes a rotating shaft symmetrically provided on the inner wall of the cabinet inner cavity and a driving assembly for driving the rotating shaft to rotate, both ends of the rotating shaft are rotatably connected to the inner wall of the cabinet, and a torsion spring is clamped at the connection between the rotating shaft and the inner wall of the cabinet, a winding wheel is fixed on the rotating shaft, and the winding wheel is connected to multiple sealing plates through a pull rope.

[0004] The beneficial effects of the above device are as follows: by setting a control mechanism, when the humidity inside the cabinet is greater than the set threshold, the control panel controls the constant humidity purification device and the servo motor to operate simultaneously, the rotation of the servo motor drives the drive shaft to rotate, and the upper rotating shaft is rotated through the bevel gear set, and the sealing plate slides upward through the action of the winding wheel and the pull rope, so that the groove is in an open state. The desiccant bag in the groove cooperates with the constant humidity purification device to quickly adjust the humidity inside the cabinet, providing good conditions for the storage of cultural relics. The setting of the torsion spring provides a force for the reverse rotation of the upper and lower rotating shafts. When the cabinet does not need to be dried, the torsion spring on the lower rotating shaft drives the winding wheel to rotate, and the sealing plate can be driven downward by the pull rope, thereby achieving the closure of the groove.

[0005] During use, the desiccant in the groove absorbs moisture from the cabinet, and the sealing plate controls the opening and closing of the groove, actively controlling the humidity within the cabinet. However, in this device, the groove is fixed relative to the cabinet interior, preventing moisture from evenly dispersing into the groove, further hindering the desiccant's ability to absorb moisture. To address this issue, we propose a constant-humidity cultural relic preservation cabinet. Utility Model Content

[0023] Example

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A constant humidity cultural relic preservation cabinet is provided. A storage platform 2 is fixedly connected to the lower end of the cabinet body 1. The storage platform 2 is used to place cultural relics for storage. A sealing cabinet door 29 is installed on the surface of the cabinet body 1 to further seal and store cultural relics placed on the surface of the storage platform 2. After the cabinet body 1 is adjusted to a constant humidity, changes in the humidity inside the cabinet body 1 can be avoided, thereby safely storing cultural relics. A humidifier 3 is fixedly connected to the surface of the cabinet body 1. A humidifier tube 4 is installed on the humidifier 3. The humidifier tube 4 is inserted into the interior of the cabinet body 1 and located below the storage platform 2. The surface of the humidifier tube 4 is provided with evenly distributed humidifying nozzles 5. When the humidifier 3 is turned on, moisture is applied to the interior of the cabinet body 1 through the humidifying tube 4 and the humidifying nozzles 5, further regulating and controlling the humidity inside the cabinet body 1. A motor 6 is fixedly connected to the inner wall of the lower end of the cabinet 1, and a fan blade 7 is fixedly connected to the output shaft of the motor 6. When the humidifying nozzle 5 sprays moisture onto the inner wall of the cabinet 1, the motor 6 is turned on and drives the fan blade 7 to rotate and form mechanical ventilation. A circulation pipe 28 is fixedly connected to the upper surface of the cabinet 1, and the other end of the circulation pipe 28 is connected to the lower end of the cabinet 1. When the fan blade 7 rotates to form mechanical ventilation, the air inside the cabinet 1 flows through the circulation pipe 28, thereby maintaining a uniform humidity inside the cabinet 1. The surface of the storage table 2 is also provided with a grid 8, which further facilitates the passage of moisture from the surface of the storage table 2, maintaining a uniform humidity above the storage table 2. At the same time, a humidity sensor 9 is fixedly connected to the surface of the storage table 2. The humidity condition of the surface of the storage table 2 can be monitored in real time by the humidity sensor 9, thereby facilitating constant humidity control of the internal humidity of the cabinet 1, thereby effectively protecting the safe storage of cultural relics.

[0026] An electric telescopic rod 14 is fixedly connected to the upper surface of the cabinet 1. A drying box 15 is fixedly connected to the piston rod of the electric telescopic rod 14. Drying box 15 is inserted into the interior of the cabinet 1. A storage chamber 16 is provided within drying box 15, which contains a desiccant 17. When the motor 6 is turned on and drives the fan 7 to rotate, it blows air from the lower opening toward the side of the drying box 15. This allows the desiccant 17 to control the moisture in the air, thereby drying the interior of the cabinet 1 and maintaining a constant humidity.

[0027] The cabinet body 1 has hinged protrusions 10 fixedly connected to the inner walls on both sides of the upper end. A hinge shaft 11 is inserted into the hinged protrusion 10. A sealing plate 12 is hinged to the surface of the hinge shaft 11, and the two sets of sealing plates 12 are symmetrically distributed. A torsion spring is installed inside the hinge shaft 11. The sealing plate 12 always rotates upward under the action of the torsion spring inside the hinge shaft 11, further controlling the movement tendency of the two sets of sealing plates 12 to always maintain a closed state. At the same time, a limiting baffle 13 is fixedly connected to the upper end surface of the hinged protrusion 10. Under the limiting action of the limiting baffle 13, the sealing plate 12 seals the interior of the cabinet body 1 when the two sets of sealing plates 12 rotate to the maximum angle. This prevents moisture in the air inside the cabinet body 1 from being absorbed by the desiccant 17, thereby achieving constant humidity control inside the cabinet body 1. When the humidity inside the cabinet 1 is adjusted, the humidifier 3 is turned on to humidify when the humidity is low, and the sealing plate 12 is opened to allow the desiccant 17 to absorb moisture and reduce the humidity, thereby further maintaining constant humidity control inside the cabinet 1.

[0028] The drying box 15 is provided with two symmetrically arranged storage chambers 16, each containing a desiccant 17. A ventilation slot 18 is also provided between the two storage chambers 16, below the circulation pipe 28. When the fan blades 7 rotate to create mechanical ventilation, air inside the cabinet 1 flows through the storage chambers 16. As air passes through the storage chambers 16, moisture is absorbed by the desiccant 17, thereby achieving humidity control.

[0029] The lower end surface of the drying box 15 is fixedly connected to a push rod 19, which is configured as a "V"-shaped structure. Two sets of mounting shafts 20 are inserted on both sides of the lower end of the push rod 19. The surfaces of the two sets of mounting shafts 20 are respectively hingedly mounted with rollers A21 and rollers B22, with roller A21 located below roller B22. When the electric telescopic rod 14 is opened, it drives the drying box 15 to rise and fall and slide within the cabinet 1. As the drying box 15 slides further, the control roller A21 contacts the surface of the sealing plate 12, pushing the sealing plate 12 to rotate against the torsion spring force inside the hinge shaft 11, thereby achieving opening and closing control between the two sets of sealing plates 12. In addition, by controlling the size of the opening and closing gap between the two sets of sealing plates 12, the desiccant 17 can achieve the desired adsorption efficiency of moisture in the air, thereby conveniently controlling the interior of the cabinet 1.

[0030] As the drying box 15 continues to slide downward, the sealing plate 12 rotates and contacts the surface of the roller B22 until the sealing plate 12 rotates to a vertical position, at which point the gap between the two sets of sealing plates 12 is maximized. At this point, the desiccant 17 has the greatest moisture absorption efficiency within the cabinet 1. A limit block 23 is fixedly connected to the upper end surface of the sealing plate 12. When the sealing plate 12 rotates to a vertical position, the limit block 23 is configured in a trapezoidal shape and faces one side of the drying box 15. A chute 24 is provided inside the drying box 15. The chute 24 is located below the storage chamber 16. A crossbar 25 is connected to the interior of the chute 24. A push block 26 is sleeved on the surface of the crossbar 25. A spring 27 is sleeved on the surface of the chute 24. One end of the spring 27 is connected to the inner wall of the drying box 15, and the other end of the spring 27 is connected to the surface of the push block 26. Under the elastic force of the spring 27, the push block 26 is always pushed toward the outside of the drying box 15. At the same time, the desiccant 17 is connected to the surface of the push block 26. As the drying box 15 continues to slide downward, the push block 26 is controlled to contact the surface of the middle limit block 23, causing the limit block 23 to push the push block 26 to slide on the surface of the cross bar 25 and compress the spring 27, causing the push block 26 to push the desiccant 17 to slide inside the storage chamber 16, further inserting the desiccant 17 into the ventilation slot 18. The two sets of desiccant 17 seal the ventilation slot 18, allowing the fan blades 7 to drive the air circulation inside the cabinet 1. When the air enters the circulation pipe 28 from the bottom of the cabinet 1, it needs to pass through the two sets of desiccant 17, further increasing the desiccant 17's ability to absorb moisture from the air and improving drying efficiency. This allows for rapid humidity adjustment inside the cabinet 1.
