Detailed Description

As shown in fig. 1, 2 and 3, the museum cultural relic protection showcase comprises a showcase base, wherein a cylindrical showcase body is arranged on the showcase base, cultural relics are arranged in the showcase body, the showcase body comprises a transparent semi-cylindrical front showcase body and an opaque semi-cylindrical rear showcase body, the front showcase body and the rear showcase body are seamlessly spliced into an integrated showcase body, a semi-cylindrical shading body is covered on the periphery of the front showcase body, a rotary transmission component is arranged on a middle shaft part at one end of the shading body, and the shading body is driven to rotate around the periphery of the showcase body by a set angle through the rotary transmission component.

Above-mentioned scheme adopts the historical relic protection showcase scheme that sets up the light-shielding body that can adjust in a flexible way on the show cabinet body, and the rotatory drive disk assembly drive light-shielding body 230 on the end of the light-shielding body 230 axle side is around the predetermined angle of rotation to the realization is opened preceding showcase body 210, satisfies personnel's visiting needs, and under the condition of no visiting personnel, exhibition cabinet body 210 before light-shielding body 230 shields, thereby avoid the historical relic in the exhibition cabinet body 200 to receive illumination, produce wearing and tearing. Therefore, compared with the existing like products, the novel cultural relic preservation device has the advantages that the illumination time of the cultural relic can be shortened, and the cultural relic preservation effect is better.

In order to realize the driving scheme of the light-shading body, as shown in fig. 1 and 2, the rotary transmission component of the scheme is a transmission bevel gear, the transmission bevel gear is meshed with the driving bevel gear, the driving bevel gear is in transmission connection with a stepping motor, the stepping motor is electrically connected with a control circuit in a control box, and the stepping motor drives the light-shading body to rotate for a set angle around the periphery of the unfolding cabinet body. Based on above scheme, in order to improve operating efficiency, as shown in fig. 1, 2, be equipped with infrared ray sensor on the showcase base front end of the preceding exhibition cabinet body department of this scheme, infrared ray sensor is connected with control circuit electricity, and control circuit controls the rotatory angle of setting of step motor drive light-shielding body according to the trigger signal that receives infrared ray sensor and send. In the above scheme, the infrared sensor 101 can sense the body temperature of a person before arriving at the showcase, so as to generate a trigger signal, thereby realizing the automatic opening of the light-shielding body 230.

In order to meet the requirement that personnel visit cultural relics and ensure that the time for opening the shading body is enough to meet the visiting requirement, the control circuit of the scheme also comprises a delayer, and the control circuit controls the stepping motor to drive the shading body to reset according to a received delay ending signal sent by the delayer. For example, after the light shielding body 230 is turned on, the time delay device starts to count time, and when the counting is finished, the stepping motor 330 drives the light shielding body 230 to rotate and reset, so as to shield the front cabinet 210. Based on the above scheme, when a person continuously visits a cultural relic and intends to visit for a longer time, the trigger signal sent by the infrared sensor in the scheme resets the timing progress of the delayer, that is, the infrared sensor 101 continuously sends out the trigger signal, and the trigger signal resets the timing progress of the delayer in real time.

In order to meet the requirements of installation of devices and components, as shown in fig. 1 and 2, the rear end of the display cabinet base is connected with the mounting frame, the mounting frame comprises a cross frame arranged above the top of the display cabinet body, and a stepping motor is arranged on the cross frame. Based on above scheme, in order to improve the stability of step motor drive shaft motion, as shown in fig. 1, 2, still be equipped with the bearing frame on the crossbearer of this scheme, step motor's output shaft erects on the bearing frame.

The scheme discloses a museum cultural relic protection showcase, and overcomes the defects of the prior art. The museum cultural relic protection showcase comprises a showcase base 100, wherein an opaque rear showcase body 220 is arranged on the showcase base 100, a transparent front showcase body 210 is arranged on the showcase base 100, and the transparent front showcase body 210 and the opaque rear showcase body 220 are seamlessly spliced into a cylindrical showcase body 200. The front end of showcase base 100 is equipped with infrared sensor 101, the rear end of showcase base 100 is fixed with mounting bracket 400, mounting bracket 400 upper end is fixed with crossbearer 410, rotatable installation has anti-dazzling screen 230 on the crossbearer 410, anti-dazzling screen 230 covers the transparent preceding showcase body 210 completely, anti-dazzling screen 230 upper end fixed mounting has transmission umbrella tooth 310, the interlock has initiative umbrella tooth 320 on the transmission umbrella tooth, step motor 330 fixed mounting is on the crossbearer 410 on mounting bracket 400, step motor 330's output shaft passes bearing frame 411 and initiative umbrella tooth 320 fixed connection, control box 340 fixed mounting is on mounting bracket 400. The transparent front cabinet 210 may be made of acrylic, glass, or other organic glass or toughened glass.

In the present apparatus, a control circuit is installed in the control box 340, and may be, for example, a PLC controller and a stepping motor driver for driving a stepping motor. When the visitors approach the infrared sensor 101, the infrared sensor 101 senses a human body temperature signal, the control box 340 controls the step motor 330 to work, the step motor 330 drives the light shielding body 230 to rotate 180 degrees through the driving bevel gear 320 and the transmission bevel gear 310, and the transparent front display cabinet body 210 is completely exposed, so that the visitors can visit cultural relics in the transparent front display cabinet body 210.

When the infrared sensor 101 does not sense the human body temperature signal, the stepping motor 330 is turned backwards after a time delay, for example, 30 seconds, so as to completely shield the light shielding body 230 on the transparent forward exhibition cabinet body 210, thereby avoiding the influence of light on the cultural relics. When someone triggers the infrared sensor 101 again within 30 seconds, the control circuit in the control box 340 delays for 30 seconds again until there is no triggering within 30 seconds, and then the stepping motor 330 rotates reversely to cover the light shielding body 230 on the transparent forward-unfolding cabinet body 210.

Based on the technical content, the light shading body 230 is opened by the infrared sensor 101 in the scheme when someone is present, so that the time of illumination acting on the cultural relic is shortened, and the better protection effect on the cultural relic is achieved.

The mechanisms, structures, components, and the like disclosed in the present embodiment can be implemented by general and conventional means known in the art, unless otherwise specified. The museum cultural relic protection showcase is not limited to the contents disclosed in the specific embodiment, the technical solutions presented in the examples can be extended based on the understanding of the technicians in the field, and the simple alternatives made by the technicians in the field according to the solution in combination with the common general knowledge also belong to the scope of the solution.
