Description

A cultural relic showcase that can prevent condensed water

technical field

The utility model relates to the technical field of display cabinets for cultural relics, in particular to a display cabinet for cultural relics that can prevent condensed water.

Background technique

In order to prevent the harm of cultural relics caused by condensed water, the museum needs to keep the cultural relics in a state of low temperature and constant temperature as much as possible when exhibiting cultural relics. Small independent showcases are often used in museums, and it is suitable to process the showcases with an independent processing system to provide a suitable temperature environment. In order to prevent the air in the showcase from condensing when it meets the colder air supply, it is required that the temperature difference of the air supply should not be too large, so it is difficult to overcome the heat load of the air in the showcase by relying on the temperature difference of the supply air. The control of the air temperature in the independent showcase is by controlling The temperature in the exhibition hall is realized indirectly, and the protection temperature of cultural relics is 16-25°C.

However, because the operating load of the temperature control system of the existing display cabinet is very large, a refrigerator needs to be installed, and the refrigerator generates relatively large noise and consumes high energy consumption when it continues to work.

In describing the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical" , "horizontal", "top", "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the utility model, rather than Any indication or implication that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should not be construed as limiting the invention.

Please refer to Figures 1-3, the utility model provides a technical solution: a cultural relic display cabinet that can prevent condensed water, including a cabinet body 1, the cabinet body 1 is provided with a through groove 2 and a boss 3, and the cabinet body 1 is provided with a round Shaped groove 4, a cylinder 15 is clamped in the circular groove 4, the circular groove 4 provides installation space for the cylinder 15, the outer surface of the cabinet body 1 is fixedly connected with a switch 5, and the upper end of the cabinet body 1 is fixedly connected with a glass cover 6 , the glass cover 6 is sealed with the cabinet body 1, and the cabinet body 1 is fixedly connected with a refrigerator 7, the model is SAC-45, which belongs to the prior art, and the upper end of the refrigerator body 7 is fixedly connected with a ventilation pipe 9, which can be installed in the cabinet body 1. For cold air delivery, a display stand 10 is fixedly connected to the upper end of the cabinet body 1, and the display stand 10 is provided with a through hole 11, which has a ventilation function. The display stand 10 is fixedly connected with a temperature controller 12, the model is STC-200, and the threshold is set. The temperature is 25°C, which belongs to the prior art. The upper end of the display stand 10 is fixedly connected with a temperature sensor 13, the model is CKWZP, which belongs to the prior art. The temperature sensor 13 is connected in series with the temperature controller 12 through a wire, and the temperature controller 12 is connected through a wire. It is connected in series with the refrigerator 7, the refrigerator 7 and the switch 5 are connected in series with the power supply of the refrigerator 7 through wires, and cultural relics 14 are placed on the upper end of the display stand 10;
