Description

Technical Field

[0001] The present invention belongs to the technical field of cultural relic protection devices, and specifically relates to an intelligent capsule box for collecting humidity-sensitive cultural relics. Background Art

[0002] A capsule box is an outer packaging container made for each cultural relic by cultural relic workers according to various factors such as the material, shape, size, and weight of the cultural relic, using special materials and a variety of manufacturing methods. From the perspective of protecting cultural relics, making capsule boxes with different styles and different internal structures for different types of cultural relics can make the cultural relics play the roles of shockproof, windproof, sun-proof, moisture-proof, and dust-proof during storage and transportation.

[0003] Since cultural relics are generally buried underground before excavation, when preserving cultural relics after excavation, in order to achieve better protection of cultural relics, the temperature and humidity in the storage environment of cultural relics are generally simulated to the temperature and humidity environment when the cultural relics were buried underground. Especially when storing some humidity-sensitive cultural relics, it is necessary to ensure that the humidity in the storage environment is as consistent as possible with that when the cultural relics were buried underground. However, the existing capsule boxes do not have the ability to adjust and simulate the control of the internal humidity, resulting in the inability to effectively protect humidity-sensitive cultural relics.

When the water level inside the water tank main body is too low, the top plate presses the first pressure sensor, and the first pressure sensor transmits a signal to the buzzer alarm. The buzzer alarm emits a beep to remind the staff to add water into the water tank main body through the water filling pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 7As shown in the figure, the embodiment of the present invention provides a smart capsule box for collecting humidity-sensitive cultural relics, including a capsule box body 1. A top cover plate 102 is installed on the top of the capsule box body 1. A humidity sensor 107 is installed in the middle of the bottom of the top cover plate 102. A control component 3 is installed inside the capsule box body 1. An activity component 4 is installed inside the control component 3. A humidifying component 5 is installed on the left side of the bottom of the activity component 4. A water tank component 2 is installed on the left side of the capsule box body 1. Ventilation components 6 are installed on both the front and back of the capsule box body 1. The control component 3 includes a support block 301 fixedly connected to the inner wall of the capsule box body 1. A fixed ring 302 is fixedly connected to the inside of the support block 301. A driving motor 303 is fixedly connected to the top of the left support block 301. The output shaft of the driving motor 303 is fixedly connected to a driving gear 304. The activity component 4 includes an annular frame 401. Annular grooves 402 are formed around the annular frame 401. Engagement teeth 403 are fixedly connected to the four sides of the top of the annular frame 401. The driving gear 304 meshes with the engagement teeth 403. The fixed ring 302 is slidably sleeved with the annular groove 402. The ventilation component 6 includes a ventilation frame 601. An electric louver 603 is installed on the inner wall of the ventilation frame 601. A dehumidifying fan 602 is installed inside the ventilation frame 601 on the back side.

[0027] In the embodiment of the present application, the support plate 106 is used to support the cultural relics. The humidity sensor 107 can monitor the humidity inside the capsule box body 1. When the humidity is lower than the set range, the atomizing mechanism 502 atomizes the water inside the atomizer housing 501 and sprays it out through the atomizing nozzle 503, thereby humidifying the inside of the capsule box body 1. The driving motor 303 is started to drive the driving gear 304 to rotate. Through the meshing action of the driving gear 304 and the engagement teeth 403, the annular frame 401 rotates in a circular motion, thereby driving the humidifying component 5 to perform a circular motion, so as to uniformly humidify the inside of the capsule box body 1. When the humidifying component 5 rotates 180 degrees to the right side, the steering sensor 306 can detect the stop block 404. Then the steering sensor 306 transmits a signal to the driving motor 303, causing the driving motor 303 to drive the driving gear 304 to reverse, and then the annular frame 401 drives the humidifying component 5 to perform a reciprocating rotation of 360 degrees. Since the second water injection pipe 505 is a flexible hose and enough length is reserved inside the capsule box body 1, the humidifying component 5 will not be stretched and straightened when performing a reciprocating circular motion. When the humidity sensor 107 detects that the humidity inside the capsule box body 1 reaches the set range, the driving motor 303 and the humidifying component 5 stop working;

[0028] With the atomization process of the humidifying component 5, the water level inside the atomizer housing 501 decreases, and the second buoyancy frame 509 is lifted by the buoyancy of the water. When the water level drops to the lowest water level height, the pressing block 510 squeezes the second pressure sensor 511, so that the second pressure sensor 511 transmits a signal to the electromagnetic control valve 504 and the water pump 204. The electromagnetic control valve 504 opens, and the electromagnetic control valve 504 pumps the water inside the water tank main body 201 into the inside of the atomizer housing 501 through the first water injection pipe 203 and the second water injection pipe 505, thereby realizing automatic water injection into the inside of the atomizer housing 501;

[0029] The water inside the water tank main body 201 has an upward buoyancy on the first buoyancy frame 207. When the water level inside the water tank main body 201 is too low, the top plate 208 squeezes the first pressure sensor 209, and the first pressure sensor 209 transmits a signal to the buzzer alarm 210. The buzzer alarm 210 emits a beep to remind the staff to add water into the water tank main body 201 through the water filling pipe 202;

[0030] When the humidity sensor 107 detects that the humidity inside the cassette body 1 exceeds the set range, the electric louver 603 automatically opens, and the dehumidifying fan 602 is started to drive the air to circulate, discharging the humid air inside the cassette body 1. The relatively dry air outside enters the inside of the cassette body 1 through the ventilation frame 601 on the front, thereby realizing the function of dehumidifying the inside of the cassette body 1.

[0031] Among them, the top of the right support block 301 is fixedly connected with a mounting block 305, and a steering sensor 306 is installed on the left side of the mounting block 305. The right side of the top of the annular frame 401 is fixedly connected with a stop block 404.

[0032] When the stop block 404 rotates to the right with the annular frame 401, the steering sensor 306 detects the stop block 404, and then the steering sensor 306 transmits a signal to the drive motor 303, so that the drive motor 303 drives the drive gear 304 to rotate in the reverse direction, and then the movable component 4 drives the humidifying component 5 to perform a 360-degree reciprocating circular motion inside the cassette body 1, avoiding the circumferential winding of the second water injection pipe 505 on the cultural relics.

[0033] Among them, the bottom of the cassette body 1 is fixedly connected with a bottom conical frame 103. A threaded cover 104 is installed in the middle of the bottom of the bottom conical frame 103.

A support leg 105 is fixedly connected to the inside of the bottom conical frame 103, and a support plate 106 is fixedly connected to the top of the support leg 105.

[0034] The bottom conical frame 103 is in a conical shape with the height around it higher than that in the middle, which can collect the condensed fog droplets and facilitate the cleaning of the inner side of the bottom conical frame 103.

[0035] Among them, the humidifying component 5 includes a nebulizer housing 501 fixedly connected to the bottom of the annular frame 401. A nebulizer nozzle 503 is arranged on the right side of the nebulizer housing 501, and a nebulizing mechanism 502 is installed at the top of the inner wall of the nebulizer housing 501.

[0036] The nebulizing mechanism 502 and the nebulizer nozzle 503 are common existing technologies for atomization, which will not be elaborated in this application.

[0037] Among them, a support plate 506 is fixedly connected to the inner wall of the nebulizer housing 501. A fixed pipe 507 is fixedly connected to the inner side of the support plate 506. A cylindrical rod 508 is movably sleeved inside the fixed pipe 507. A second buoyancy frame 509 is fixedly connected to the top of the cylindrical rod 508. A pressing block 510 is fixedly connected to the bottom of the cylindrical rod 508. A second pressure sensor 511 is installed at the bottom of the inner wall of the nebulizer housing 501. An electromagnetic control valve 504 is installed at the bottom of the nebulizer housing 501. A second water injection pipe 505 is fixedly connected to the bottom of the electromagnetic control valve 504.

[0038] The second pressure sensor 511 is electrically connected to the electromagnetic control valve 504. During normal use, the electromagnetic control valve 504 is in a closed state. When the water level inside the nebulizer housing 501 is too low, the pressing block 510 squeezes the second pressure sensor 511, and the second pressure sensor 511 transmits a signal to the electromagnetic control valve 504, facilitating water to be injected into the inside of the nebulizer housing 501 through the second water injection pipe 505.

[0039] Among them, the water tank assembly 2 includes a water tank main body 201 fixedly connected to the left side of the cassette body 1.

A water pump 204 is installed at the bottom of the inner wall of the water tank main body 201.

[0040] The water outlet of the water pump 204 is communicated with the first water injection pipe 203, and the water pump 204 is electrically connected to the second pressure sensor 511. The staff can add water to the inside of the water tank main body 201 through the water filling pipe 202.

[0041] Among them, a positioning pipe 205 is fixedly connected to the top of the inner wall of the water tank main body 201. A movable rod 206 is movably sleeved inside the positioning pipe 205. A first buoyancy frame 207 is fixedly connected to the bottom of the movable rod 206. A top plate 208 is fixedly connected to the top of the movable rod 206. A first pressure sensor 209 is installed on the left side of the top of the water tank main body 201. A buzzer 210 is installed on the top left side of the water tank main body 201.

[0042] The first pressure sensor 209 is electrically connected to the buzzer alarm 210. Water exerts an upward buoyant force on the first buoyancy frame 207. The staff can judge the water volume inside the water tank main body 201 through the height of the top plate 208.

[0043] Working principle and usage process:

[0044] The support plate 106 is used to support the cultural relic. The humidity sensor 107 can monitor the humidity inside the capsule body 1. When the humidity is lower than the set range, the atomizing mechanism 502 atomizes the water inside the atomizer housing 501 and sprays it out through the atomizing nozzle 503, thereby humidifying the inside of the capsule body 1. The driving motor 303 is started to drive the driving gear 304 to rotate. Through the meshing action of the driving gear 304 and the meshing teeth 403, the annular frame 401 rotates in a circle, thereby driving the humidifying assembly 5 to perform circular motion, so as to uniformly humidify the inside of the capsule body 1. When the humidifying assembly 5 rotates 180 degrees to the right, the steering sensor 306 can detect the stopper 404. Then the steering sensor 306 transmits a signal to the driving motor 303, causing the driving motor 303 to drive the driving gear 304 to reverse, and then the annular frame 401 drives the humidifying assembly 5 to perform a 360-degree reciprocating rotation. Since the second water injection pipe 505 is a flexible hose and there is enough length reserved inside the capsule body 1, the humidifying assembly 5 will not be pulled and straightened during the reciprocating circular motion. When the humidity sensor 107 detects that the humidity inside the capsule body 1 reaches the set range, the driving motor 303 and the humidifying assembly 5 stop working;

[0045] As the atomizing process of the humidifying assembly 5 proceeds, the water level inside the atomizer housing 501 drops. Under the buoyant force of the water, the second buoyancy frame 509 is lifted. When the water level drops to the lowest water level height, the pressing block 510 squeezes the second pressure sensor 511. Then the second pressure sensor 511 transmits a signal to the electromagnetic control valve 504 and the water pump 204. The electromagnetic control valve 504 opens, and the electromagnetic control valve 504 pumps the water inside the water tank main body 201 into the inside of the atomizer housing 501 through the first water injection pipe 203 and the second water injection pipe 505, thereby realizing automatic water injection into the inside of the atomizer housing 501;

[0046] The water inside the water tank main body 201 exerts an upward buoyant force on the first buoyancy frame 207. When the water level inside the water tank main body 201 is too low, the top plate 208 squeezes the first pressure sensor 209. The first pressure sensor 209 transmits a signal to the buzzer alarm 210, and the buzzer alarm 210 emits a beep to remind the staff to add water into the water tank main body 201 through the water filling pipe 202;

[0047] When the humidity sensor 107 detects that the humidity inside the cassette body 1 exceeds the set range, the electric louver 603 automatically opens, and the dehumidification fan 602 is started to drive air circulation, discharging the humid air inside the cassette body 1. The relatively dry air outside enters the inside of the cassette body 1 through the ventilation frame 601 on the front, thereby achieving the function of dehumidifying the inside of the cassette body 1.

[0048] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
