Description

Technical Field

[0001] The present invention relates to the technical field of microenvironment governance, and specifically to a microenvironment governance device for an archaeological site park. Background Art

[0002] An archaeological site park refers to a specific public space with the main body being an important archaeological site and its background environment, having functions such as scientific research, education, and recreation, and being of national demonstration significance in the protection and display of archaeological sites. Inside the archaeological site park, cultural relics of historical value are displayed for tourists to visit. During the visit, the carbon dioxide exhaled by tourists will remain indoors. As the number of tourists increases, the concentration of carbon dioxide in the room also increases. With the increase in the concentration of carbon dioxide, carbon dioxide can combine with water in the air to form carbonic acid, causing corrosion to stone and metal cultural relics such as white marble and bronze. Therefore, in the prior art, fresh air systems are installed indoors for internal and external air exchange treatment. However, most of the existing fresh air devices are installed at high positions and the positions of the air extraction ports are fixed. Since the density of carbon dioxide is greater than that of air, carbon dioxide mostly sinks to lower positions. Therefore, the efficiency of treating carbon dioxide at lower positions is reduced.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] refer to Figure 1-8, Equipment Installation and Overall Structure: The microenvironment treatment equipment for this archaeological site park mainly consists of an air filtration box body 3, a multi-layer activated carbon filter screen 26, an exhaust fan 19, a base 12, etc. The base 12 is fixed to the ground by screws, facilitating maintenance operations by the staff. Above the air filtration box body 3, there is a fixed sliding rod 8, and a sliding pipe fitting 18 is sleeved on the fixed sliding rod 8 to ensure its sliding stability, thereby enhancing the smoothness of the air filtration box body 3 during movement. On one side of the sliding pipe fitting 18, a first driving motor 5 is installed, and the driving gear 6 at its movable end meshes with a rack 9. Both ends of the rack 9 are fixed by support blocks 2. Between the support block 2 and the base 12, there is a ball screw 11. The support block 2 is slidably installed on the support rod 10 at the top of the base 12, and the ball screw 11 is installed on the screw fixing frame 1 at the top of the base 12, which is used to drive the air filtration box body 3 to move vertically. The transmission mechanism between the two ball screws 11 includes a transmission shaft 14, a first bevel gear 13, a second bevel gear 16, etc. The second driving motor 15 drives the transmission shaft 14 to rotate through two second bevel gears 16, and the transmission shaft 14 then drives the screw rods of the two ball screws 11 to rotate through two first bevel gears 13, realizing the synchronous operation of the two ball screws 11 and ensuring the stability of the air filtration box body 3 during height adjustment.

[0026] Swinging Head Movement Mechanism: The swinging head movement mechanism between the rack 9, the sliding pipe fitting 18, and the air filtration box body 3 consists of a driven gear 7, a rotating shaft 29, a second sector gear 30, a first sector gear 22, a movable shaft 20, a fixed plate 21, a torsion spring 27, etc. When the sliding pipe fitting 18 moves horizontally, it drives the rotating shaft 29 and the driven gear 7 to move on the rack 9, and the rotation of the driven gear 7 causes the second sector gear 30 to rotate synchronously. When the toothed part of the second sector gear 30 meshes with the toothed part of the first sector gear 22, it drives the first sector gear 22 and the movable shaft 20 to move, causing the air filtration box body 3 to swing. At this time, the torsion spring 27 stores energy; when their toothless parts correspond, the torsion spring 27 rebounds to reset the air filtration box body 3. In this cycle, the air filtration box body 3 swings intermittently, expanding the air extraction range.

[0027] Functions and connection methods of other components: The mounting block 17 on the side of the sliding pipe fitting 18 fixes the first driving motor 5 to enhance its stability. The connecting rod 28 at the bottom of the sliding pipe fitting 18 fixes and supports the annular plate 24, and the connecting column 25 at the bottom of the air filter box 3 is inserted into the inner hole of the supporting annular plate 24, facilitating the horizontal swing of the air filter box 3 and improving its stability. The dovetail groove 31 on the side of the support block 2 cooperates with the dovetail block 32 to prevent the support block 2 from deviating when sliding vertically. The travel switch 23 on the side of the support block 2 cooperates with the push blocks 4 at both ends of the sliding pipe fitting 18 to control the forward and reverse rotations of the first driving motor 5 and the second driving motor 15, realizing the reciprocating movement of the air filter box 3.

[0028] Equipment working process: When in use, connect the two travel switches 23 to the exhaust fan 19, the first driving motor 5 and the second driving motor 15 and turn on the power supply. The exhaust fan 19 works to create a negative pressure inside the air filter box 3. The outside air carrying carbon dioxide enters through the air inlet and is adsorbed and purified by the multi-layer activated carbon filter screen 26, and the treated gas is discharged from the air outlet. The first driving motor 5 drives the air filter box 3 to move horizontally and swing intermittently, and the second driving motor 15 makes it move in the vertical direction through the ball screw 11, expanding the air intake range and improving the purification efficiency.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
