[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0027] The following is combined with Figure 1-Figure 6 The specific implementation modes of the present invention are described in further detail.

[0028] Depend on Figure 1-Figure 6 As shown, the present invention includes a placement bin 1 and a placement plate 2 for placing cultural relics. In order to facilitate the purpose of surface spraying and humidifying cultural relics of different shapes, the placement plate 2 is located inside the placement bin 1. A rotatable adjustment mechanism 3 is provided on the top of the placement bin 1. A telescopic mechanism 4 with adjustable length is connected to the lower part of the adjustment mechanism 3. A spray head 5 for spraying the cultural relics is provided on the lower side of the telescopic mechanism 4. The spray head 5 is an atomizing spray head, which will not be described in detail here. A conveying pipe 6 is provided on the upper side of the placement bin 1. A first liquid storage barrel 7 and a second liquid storage barrel 8 are provided on the left side of the placement bin 1. A switching mechanism 9 for switching the spray liquid is provided on the left side of the placement bin 1. A rotating block 10 is rotatably connected to the top of the inner side of the placement bin 1. Two baffle cloths are provided on the front side of the placement bin 1. The first liquid storage barrel 7 is used to store reagents for spraying the surface of the cultural relics. The second liquid storage barrel 8 is used to store deionized water for cleaning the spray pipe to avoid reagent residue.

[0029] When in use, the cultural relics can be placed on the placement plate 2, and then the position of the spray head 5 can be changed by the adjustment mechanism 3 and the telescopic mechanism 4. At this time, the delivery pipe 6 can spray the reagent in the first liquid storage barrel 7, and then spray the surface of the cultural relics. During the spraying process, the adjustment mechanism 3 will drive the telescopic mechanism 4 and the spray head 5 to rotate together, so that the cultural relics can be sprayed 360 degrees. After the reagent spraying is completed, the cultural relics can be taken out, and then under the action of the switching mechanism 9, the second liquid storage barrel 8 can be connected with the spray head 5, and then deionized water can be sprayed through the spray head 5 to clean the delivery pipe 6 and the connecting pipe 33 to avoid reagent residue;

[0030] It should be further explained that, due to the different treatment processes required for the surface of the cultural relics, the surface of the cultural relics can be cleaned or reinforced and sealed. Therefore, for different treatment processes, the types of reagents in the first liquid storage barrel 7 are also different. When reinforcing and sealing the surface of the cultural relics, the reagent in the first liquid storage barrel 7 is a reinforcement protection reagent. At this time, the deionized water in the second liquid storage barrel 8 can be used to flush the delivery pipe 6; when cleaning, the reagent in the first liquid storage barrel 7 corresponds to deionized water. At this time, the deionized water in the second liquid storage barrel 8 can flush the inside of the placement bin 1 during the spraying process;

[0031] Furthermore, in order to facilitate different protection processes for different cultural relics, the number of first liquid storage barrels 7 can be set to multiple, and different reagents can be stored in different first liquid storage barrels 7. When performing different treatment processes (such as cleaning, surface reinforcement and sealing, etc.), the lower end of the three-way pipe 35 can be connected to the corresponding first liquid storage barrel 7.

[0032] Further, in order to improve the stability of the spraying, the adjustment mechanism 3 includes a moving block 11 that can rotate inside the placement bin 1, two connecting plates 12 are fixedly connected to the upper side of the moving block 11, a rotatable rotating shaft 13 is provided on the upper side of the moving block 11, the rotating shaft 13 is rotatably connected to the two connecting plates 12, a moving wheel 14 is fixedly connected to each of the two ends of the rotating shaft 13, and a first limiting ring 15 and a second limiting ring 16 are fixedly connected to the top of the inner side of the placement bin 1;

[0033] Furthermore, in order to make the operation of the device more stable, a large toothed ring 17 fixedly connected to the placement bin 1 is provided between the first limiting ring 15 and the second limiting ring 16, a first gear 18 is fixedly connected to the middle of the rotating shaft 13, the upper side of the first gear 18 is meshed with the large toothed ring 17, and the lower side of the first gear 18 is meshed with a second gear 19 rotatably connected to the moving block 11, one end of the moving block 11 is fixedly connected to a first motor 20, and the output end of the first motor 20 is fixedly connected to the second gear 19;

[0034] It should be noted that the large gear ring 17, the first gear 18 and the second gear 19 are all bevel gears;

[0035] When in use, the moving wheel 14 contacts the first limiting ring 15 and the second limiting ring 16. After the first motor 20 is started, the first motor 20 drives the first gear 18 to rotate through the second gear 19. Since the large gear ring 17 is fixedly connected to the placement bin 1, the first gear 18 will drive the two connecting plates 12 to move through the rotating shaft 13, thereby enabling the moving block 11 to move along the first limiting ring 15 and the second limiting ring 16, and thus drive the telescopic mechanism 4 to rotate around the cultural relics.

[0036] Furthermore, in order to be able to spray and rinse cultural relics at different heights, the adjustment mechanism 3 includes a first sleeve 21 rotatably connected to the adjustment mechanism 3, a second sleeve 22 is slidably connected inside the first sleeve 21, the spray head 5 is communicated with the bottom of the second sleeve 22, a first telescopic rod 23 is fixedly connected to one side of the first sleeve 21, and the second sleeve 22 is fixedly connected to the moving end of the first telescopic rod 23; the first telescopic rod 23 is an electric telescopic rod, which is a prior art and will not be described in detail here;

[0037] When in use, by starting the electric telescopic rod, the second sleeve 22 can be driven to be telescoped relative to the first sleeve 21, thereby driving the sprinkler head 5 to be adjusted in height.

[0038] Furthermore, in order to be able to wash the cultural relics at different angles, a first tilting rod 24 is rotatably connected to the bottom of the rotating block 10, a first threaded rod 25 is fixedly connected to the side of the first tilting rod 24 away from the rotating block 10, a second tilting rod 26 is rotatably connected to the side of the first sleeve 21 close to the rotating block 10, a second threaded rod 27 is fixedly connected to the side of the second tilting rod 26 away from the first sleeve 21, the first threaded rod 25 and the second threaded rod 27 have opposite thread rotation directions, and a threaded sleeve 28 is meshed with the outer sides of the first threaded rod 25 and the second threaded rod 27;

[0039] Furthermore, in order to facilitate the operation of the staff, a second motor 29 is fixedly connected to the upper side of the first tilting rod 24, a third gear 30 is fixedly connected to the output end of the second motor 29, a fourth gear 31 is fixedly connected to the outer side of the threaded sleeve 28, and the third gear 30 is meshed with the upper side of the fourth gear 31;

[0040] It should be noted that the third gear 30 and the fourth gear 31 are both spur gears;

[0041] When in use, by starting the second motor 29, the second motor 29 drives the fourth gear 31 to rotate relative to the first tilting rod 24 through the third gear 30, and then drives the threaded sleeve 28 to rotate. Since the first threaded rod 25 and the second threaded rod 27 have opposite thread rotation directions, when the threaded sleeve 28 rotates, it will drive the first threaded rod 25 and the second threaded rod 27 to move closer to or away from each other, and the angle of the first sleeve 21 relative to the moving block 11 is adjusted through the second tilting rod 26, thereby achieving the purpose of adjusting the position of the sprinkler head 5.

[0042] Furthermore, in order to monitor the spraying position, an angle sensor 32 is provided on the outer side of the rotating block 10, and a connecting pipe 33 is connected to the side of the delivery pipe 6 close to the rotating block 10 through a rotating joint, and the side of the connecting pipe 33 away from the rotating block 10 is connected to the first sleeve 21;

[0043] When in use, the angle of the current spray head 5 relative to the object can be monitored in real time through the angle sensor 32. Furthermore, the angle sensor 32 is electrically connected to the switching mechanism 9. When it is detected that the spray angle to the object is greater than 360°, an electrical signal is sent to operate the switching mechanism 9 to rinse the delivery pipe 6 and the inside of the connecting pipe 33 with deionized water.

[0044] Furthermore, in order to facilitate multi-step spraying of cultural relics, a water pump 34 is provided on the side of the delivery pipe 6 away from the rotating block 10, and a three-way pipe 35 is connected to the water inlet end of the water pump 34, and two liquid inlet ends of the three-way pipe 35 are respectively connected to the first liquid storage barrel 7 and the second liquid storage barrel 8;

[0045] Furthermore, in order to be able to automatically spray the cultural relics, the switching mechanism 9 includes a blocking frame 36 fixedly connected to the placement bin 1, the bottom of the blocking frame 36 is rotatably connected to a connecting frame 37, the side of the connecting frame 37 close to the three-way pipe 35 is fixedly connected to an arc plate 38, the bottom of the connecting frame 37 is fixedly connected to a fifth gear 39, one side of the fifth gear 39 is meshed with a sixth gear 40, the outer side of the placement bin 1 is fixedly connected to a third motor 41, and the output end of the third motor 41 is fixedly connected to the sixth gear 40; a boss 42 is fixedly connected to the middle of the placement plate 2, and a plurality of drainage holes 43 are provided on the placement plate 2;

[0046] It should be noted that the fifth gear 39 and the sixth gear 40 are both spur gears;

[0047] When in use, after starting the water pump 34, the arc plate 38 is in the extreme position on the rear side, that is, the arc plate 38 and the blocking frame 36 cooperate with each other to press and block the position where the three-way pipe 35 is connected to the second liquid storage barrel 8. At this time, under the action of the water pump 34, the solution inside the first liquid storage barrel 7 is transported into the first sleeve 21 through the delivery pipe 6 and the connecting pipe 33, and then sprayed from the spray head 5 through the second sleeve 22 to spray the cultural relics. When the third motor 41 receives the signal sent by the angle sensor 32, it will rotate, and drive the fifth gear 39 to rotate through the sixth gear 40, and then drive the arc plate 38 to rotate under the action of the connecting frame 37, so that it presses and blocks the position where the three-way pipe 35 is connected to the first liquid storage barrel 7, so that the water pump 34 draws liquid from the second liquid storage barrel 8 for spraying. In the process of spraying the objects, the flowing liquid will be discharged from the drainage hole 43. The design of the boss 42 can make it more convenient for the staff to check the status of the cultural relics.

[0048] It should be noted that the first motor 20, the second motor 29 and the third motor 41 are all servo motors, which are all prior art and will not be described in detail here;

[0049] It should be further explained that a controller, such as a PLC controller, is provided inside the placement bin 1. The first motor 20, the second motor 29, the angle sensor 32, the third motor 41, the water pump 34, and the first telescopic rod 23 are all connected to the controller. A control panel that is communicated with the controller is provided on the outside of the placement bin 1 for detailed adjustment and control of each component. While the adjustment mechanism 3 and the telescopic mechanism 4 are driven to rotate by the rotation of the first motor 20, the adjustment mechanism 3 and the telescopic mechanism 4, under the action of the controller, will drive the spray head 5 to adjust the height together. Since the spray head 5 is an atomizing spray head, its spray angle is large. While the liquid delivery speed of the water pump 34 is uniform, the spray head 5 can evenly spray the surrounding surfaces of the cultural relics.

[0050] When the present invention is used, the cultural relics can be placed on the placement plate 2 first, and then the position of the spray head 5 can be changed through the adjustment mechanism 3 and the telescopic mechanism 4. At this time, the delivery pipe 6 can spray the solution in the first liquid storage barrel 7, and then spray the surface of the cultural relics. In the process of spraying the solution, the adjustment mechanism 3 will drive the telescopic mechanism 4 and the spray head 5 to rotate together, so that the cultural relics can be sprayed 360°. After the reagent spraying is completed, under the action of the switching mechanism 9, the second liquid storage barrel 8 can be connected with the spray head 5, and then deionized water can be sprayed through the spray head 5 to clean the delivery pipe 6 and the connecting pipe 33.

[0051] The invention has a novel structure, an ingenious conception, and is simple and convenient to operate. Through this design, cultural relics with different surface shapes can be effectively and conveniently sprayed. The operation of the device is stable, the solution spraying is stable and uniform, and can be monitored in real time, thus overcoming the disadvantage of uneven surface painting caused by manual painting.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
