Description

Technical Field

[0001] The present invention relates to the technical field of model platforms, and in particular to a land use and protection program model platform. Background Art

[0002] Land use protection refers to the rational use of land resources and taking measures to protect the land environment to ensure the sustainable use of land resources. Specifically, land use protection includes the following aspects: rational use of land resources, protection of land environment, legal and regulatory support, comprehensive management measures and sustainable use. The sustainable use of land resources is the premise and condition for the coordinated development of population, environment and social economy. Rational development, utilization, remediation and protection of land resources ensure the long-term stability and effective use of land resources. When formulating land use plans, land model research can be used more reasonably, which requires a land use and protection plan model platform.

[0003] The Chinese patent with the authorization announcement number CN219476251U discloses a land use and protection scheme model platform, including: a base, a mounting slot is provided on the base, a cover assembly is provided at the upper end of the mounting slot; a display assembly includes a bottom plate, the bottom plate is provided in the mounting slot, a lifting mechanism is provided between the bottom plate and the base, a display box is provided on the bottom plate, a rotating mechanism is provided between the bottom plate and the display box, the rotating mechanism includes a first motor, the first motor is fixedly connected to the bottom plate, a support ring is fixedly connected to the bottom surface of the display box, and the support ring is rotatably connected to the bottom plate through a bearing.

[0004] Although the above-mentioned land use and protection plan model platform can realize multi-angle display of the display box and can retract the display box when not on display, after the display box is retracted, its external protective device is still in an exposed state, and it is impossible to avoid collision and damage from above; the device lacks a dust cleaning structure, which is not convenient for automatically cleaning the dust on the platform surface. During a long period of display, it is inevitable that a lot of dust will adhere to the device. Failure to clean it in time will affect the display effect. Summary of the invention

During a long display process, a lot of dust will inevitably adhere to the device, and if it is not cleaned in time, it will affect the display effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a land use and protection program model platform, comprising:

[0007] A model box, wherein a lifting platform is installed inside the model box, and a display stand is installed above the lifting platform, a transparent protective cover is installed above the display stand, and a steering motor is connected to the middle of the lower end surface of the display stand;
