Description

Technical Field

[0001] The utility model relates to the field of architecture, in particular to architectural technology related to heritage site protection and exhibition. Background Art

[0002] In order to allow visitors to appreciate the ruins without causing damage to the ruins, many ruins have adopted the solution of installing glass floors on the ruins. Visitors can appreciate the ruins through the glass floors, while avoiding damage to the ruins. Among them, the glass floor includes a steel support frame, on which multiple pieces of tempered glass are installed.

[0003] The ruins are protected by glass, but the ruins are connected to the natural soil layer, so it is easy for mold to grow under the glass due to moisture, and cause water mist to adhere to the lower surface of the glass floor, which is not only not conducive to the protection of the ruins, but also makes it difficult for visitors to see the ruins through the water mist. The space under the glass is limited, and cleaning work is very troublesome or even impossible, which requires a ventilation system to avoid moisture.

[0004] The existing ventilation system of the ruins uses mechanical forced ventilation, which consumes a lot of energy. In addition, the ruins need to be closed during the off-season, and the fans are turned off after closing (if the power is not turned off after closing, there may be safety hazards). It is difficult to avoid moisture in the ruins, which is easy to breed microorganisms and mold. Once microorganisms and mold appear, it is very troublesome to clean them up, or even impossible to remove them completely.

[0005] The design idea of ​​the utility model is to design an exhaust ventilation system, which uses exhaust ventilation to achieve non-powered ventilation 365 days a year. Power outages when the museum is closed will not affect the ventilation. The structural design allows the wind to pass through every part of the lower surface of the glass floor, avoiding ventilation dead corners that may cause local glass fogging and local ruins to become damp. Utility Model Content

[0006] The utility model aims to provide a glass floor ventilation and demisting system for cultural relics, which realizes uninterrupted ventilation by means of air extraction ventilation, and the continuous ventilation is not affected by power failure of the equipment when the museum is closed.

[0007] In order to achieve the above-mentioned purpose, the cultural heritage glass floor ventilation and demisting system of the utility model is used for cultural heritage, and a protective wall is arranged around the cultural heritage, and a steel support frame is connected to the top of the protective wall, and a plurality of tempered glass are connected to the steel support frame, and the steel support frame and the tempered glass form a glass floor, and a heritage cavity is enclosed between the glass floor and the cultural heritage below, and a roof is arranged above the glass floor, and a viewing hall is enclosed between the roof and the glass floor;

[0008] There is an air extraction pipe connected between the roof and the glass floor. The air extraction pipe is connected downward to the cavity of the ruins, and extends upward to the roof to communicate with the atmosphere.

[0009] The steel support frame is also provided with a long air inlet made of a metal grille. The long air inlet is adjacent to the tempered glass. The long air inlet is connected to the cavity of the ruins downwards and connected to the viewing hall upwards.

[0010] The glass floor is rectangular as a whole, the air extraction pipe is located at a corner of the rectangle, the two sides of the glass floor adjacent to the air extraction pipe are called the first side and the second side, the other two sides of the glass floor are called the third side and the fourth side, and the long air inlet is arranged along the third side and the fourth side of the glass floor and is L-shaped.

[0011] A rotating hood is provided at the top of the air extraction tube to prevent rainwater or debris from entering the air extraction tube.

[0012] A manual air valve is installed on the air extraction pipe in the viewing hall, and the manual air valve is at least 1.2 meters above the glass floor.

[0013] The utility model has the following advantages:

[0014] The structure of the utility model is adopted, and the characteristic that the air pressure at a high place is lower than the air pressure at a low place is utilized, so that the gas in the viewing hall continuously enters the cavity of the ruins through the long air inlet, and then is discharged to the sky through the air extraction pipe, thereby forming a continuous airflow in the cavity of the ruins, realizing unpowered uninterrupted ventilation, and even if the power supply of the museum is completely cut off when the museum is closed, it will not affect the continuous ventilation of the cavity of the ruins. In this way, the problem of moisture, breeding of microorganisms and mold in the ruins is avoided.

[0015] The air extraction duct is arranged diagonally opposite to the long air inlet, and the long air inlet is set along the third and fourth sides of the glass floor. In this way, the airflow from the long air inlet to the air extraction duct will cover the entire lower surface of the glass floor, eliminating ventilation dead corners and avoiding the phenomenon of local glass fogging and local ruins getting damp due to the existence of ventilation dead corners.

[0016] The rotating hood prevents rain or debris from entering the exhaust pipe, ensuring the long-term stable operation of the system. When performing maintenance work on the site space, it may be necessary to stop the exhaust ventilation. The manual air valve is set to facilitate stopping the exhaust ventilation by closing the manual air valve. When there is a strong wind at high altitude, the air pressure at high altitude is lower due to the air flow. In this case, the intensity of the exhaust ventilation will increase significantly. At this time, by closing the manual air valve (reducing the opening degree of the manual air valve), the intensity of the exhaust ventilation can be made more stable. The exhaust pipe has a regular shape, so it will not hurt too much even if a child touches it. The manual air valve has an irregular shape and is made of hard material. It may hurt a child if it touches it by mistake. Since the manual air valve is at least 1.2 meters above the glass floor, it can prevent children from being frightened by touching the manual air valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 2 It is a plan view of the air extraction duct and air inlet. DETAILED DESCRIPTION

[0019] like Figure 1 and Figure 2 As shown, the ventilation and demisting system for the glass floor of a cultural heritage site 1 of the utility model is used for the cultural heritage site 1, a surrounding wall 2 is arranged around the cultural heritage site 1, a steel support frame 3 is connected to the top of the surrounding wall 2, a plurality of tempered glass 4 are connected to the steel support frame 3, the steel support frame 3 and the tempered glass 4 form a glass floor, a heritage cavity 5 is enclosed between the glass floor and the cultural heritage site 1 below, a roof 6 is arranged above the glass floor, and a viewing hall 7 is enclosed between the roof 6, the glass floor and the surrounding wall 2;

[0020] A degassing pipe 8 is connected between the roof 6 and the glass floor. The degassing pipe 8 is communicated downward with the ruins cavity 5, and extends upward from the roof 6 to communicate with the atmosphere.

[0021] The steel support frame 3 is also provided with a long air inlet 9 made of a metal grille, the long air inlet 9 is adjacent to the tempered glass 4, the long air inlet 9 is connected to the ruins cavity 5 downward, and the long air inlet 9 is connected to the viewing hall 7 upward.

[0022] The structure of the utility model is adopted, and the characteristic that the air pressure at a high place is lower than the air pressure at a low place is utilized, so that the gas in the viewing hall 7 continuously enters the ruins cavity 5 through the long air inlet 9, and then is discharged to the sky through the air extraction pipe 8, thereby forming a continuous airflow in the ruins cavity 5, realizing uninterrupted ventilation, and even if the power supply of the museum is completely cut off when the museum is closed, it does not affect the continuous ventilation of the ruins cavity 5. In this way, the problem of moisture, breeding of microorganisms and mold at the ruins is avoided.

[0023] The glass floor is rectangular as a whole, and the air extraction pipe 8 is located at a corner of the rectangle. The two sides of the glass floor adjacent to the air extraction pipe 8 are called the first side 10 and the second side 11, and the other two sides of the glass floor are called the third side 12 and the fourth side 13. The long air inlet 9 is arranged along the third side 12 and the fourth side 13 of the glass floor and is L-shaped.

[0024] The top of the air extraction pipe 8 is provided with a rotating hood 14 for preventing rainwater or debris from entering the air extraction pipe 8. The rotating hood 14 prevents rainwater or debris from entering the air extraction pipe 8, ensuring long-term stable operation of the system.

[0025] A manual air valve 15 is provided on the degassing pipe 8 in the viewing hall 7, and the manual air valve 15 is at least 1.2 meters above the glass floor. When performing maintenance work on the ruins space, it may be necessary to stop the degassing ventilation. The setting of the manual air valve 15 is convenient for stopping the degassing ventilation by closing the manual air valve 15. When there is a strong wind at high altitude, the air pressure at high altitude is lower due to the air flow. In this case, the intensity of the degassing ventilation will increase significantly. At this time, by closing the manual air valve 15 (reducing the opening degree of the manual air valve 15), the intensity of the degassing ventilation can be made more stable. The degassing pipe 8 has a regular shape, and it will not hurt too much even if a child touches it. The manual air valve 15 has an irregular shape and is made of hard material. It may hurt a child if it touches it by mistake. Since the manual air valve 15 is at least 1.2 meters above the glass floor, it can prevent the child from being frightened by touching the manual air valve 15.

[0026] During installation, since the air extraction pipe 8 and the long air inlet 9 in the utility model are both located at the corners of the glass floor, and the corners of the glass floor are usually located outside the scope of the cultural relics 1, the installation operation will basically have no impact on the cultural relics 1, and the installation operation has a high safety of cultural relics. During normal use, the manual air valve 15 is opened. Since the air pressure at a high place is lower than the air pressure at a low place, the gas in the site space is continuously dispersed into the high environment through the air extraction pipe 8. Since the long air inlet 9 is arranged diagonally with the air extraction, and the long air inlet 9 is arranged along the third side 12 and the fourth side 13 of the glass floor, the airflow from the long air inlet 9 to the air extraction pipe 8 will cover the lower surface of the entire glass floor, eliminating ventilation dead corners, and avoiding the phenomenon of local glass fogging and local cultural relics 1 being damp due to the existence of ventilation dead corners.

[0027] When encountering strong winds and the gas pressure at high altitudes is low, a greater ventilation intensity may be generated. At this time, appropriately reducing the opening degree of the manual air valve 15 can offset the impact of strong winds, making the ventilation intensity more stable and not causing any impact on the cultural relics 1 due to strong airflow.

[0028] When the museum is closed during the off-season, even if all the electricity in the museum is shut down, the ventilation will not be interrupted to avoid the cultural relics and glass floor getting damp due to power outages during the off-season.
