Three-dimensional electronic sand table cleaning method for urban planning and design

Abstract

The invention relates to the technical field of urban planning and design, in particular to a three-dimensional electronic sand table cleaning method for urban planning and design. A threaded sleeve drives a cleaning plate below the threaded sleeve to move left and right, so that the cleaning plate moves and scrapes sand grains to the left and right sides. When the sand grains fall into a recoveryseat through an inclined recovery plate, according to the Bernoulli principle, the flow speed of the bottom of the recovery seat is large, and the pressure intensity of the position with large flow speed is small. A pressure collecting bag is movably connected to one side of the recovery seat, air flow can flow to one side of the pressure collecting bag due to the pressure intensity difference onone side of the recovery seat, and an extension spring is arranged in the pressure collecting bag, so that when the air flow enters the pressure collecting bag under the pressure intensity differenceeffect, the pressure collecting bag can be changed from a compressed state to an extended state, and at the moment, the pressure collecting bag can generate certain suction force. At the moment, external floating dust can be sucked, so that the cleanness of the surface of a sand table is guaranteed, the phenomenon that the dust floats around is avoided, and convenience is brought to the use of workers.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to a three-dimensional electronic sand table cleaning method for urban planning and design. Background technique [0002] Urban planning and design should provide smart city solutions related to design, technology, products, investment, and operation based on the development goals of smart cities, and guide the construction of smart cities in a certain period of time in the future. According to objective conditions such as the environment, human conditions, and economic development status, formulate a plan for the overall development of the city, thereby coordinating the development of all aspects of the city, and further comprehensively deploying and coordinating the spatial layout, land use, and infrastructure construction of the city. Work strategically and comprehensively. [0003] When using the sand table, the sand grains are often uneven, and it is generally troubleso...

Problems solved by technology

[0003] When using the sand table, the sand grains are often uneven, and it is generally troublesome to level it, and after use, the cleaning effect on the sand grains of the sand table is not good, and it often occurs during cleaning. There is a lot of dust, which affects the use of staff. Therefore, in view of this, we will study and improve the existing structure and defects, and provide a three-dimensional electronic sand table cleaning method for urban planning and design, in order to achieve more practical value. the goal of
