Abstract

This utility model provides a construction surveying device, belonging to the field of construction technology. It includes a surveying vehicle body. A level detector is mounted on the bottom of the vehicle body via multiple sets of fastening bolts. A dust cover is mounted on the level detector and is fixedly engaged with the bottom of the vehicle body. A dust removal scraper is located on the outside of the dust cover, with its control end extending to a push rod on the vehicle body. Multiple rotating seats are symmetrically arranged on the bottom of the vehicle body, each containing a high-pressure air nozzle connected by threads. The air inlet of the high-pressure air nozzle extends into the interior of the vehicle body, and a threaded fastening sleeve is fitted around its outer periphery. A rectangular mounting slot is provided on the top of the vehicle body, with a support component mounted on it. A fan is mounted on the support component, and the fan's bottom outlet is threadedly connected to the threaded fastening sleeve via a flexible hose. This device, through the dust removal and protection assembly consisting of the fan and the high-pressure air nozzle, improves the cleanliness of the measurement environment.
