Problems solved by technology

[0003] Most of the existing handheld measuring devices are exposed outside when they are not in use. The engineer does not protect the outside of the measuring instrument tightly enough during the carrying process, which causes the device to fall, causing unnecessary losses and affecting the use of the staff.

Abstract

The invention belongs to the technical field of engineering surveying and mapping, and particularly relates to a precise and durable handheld measuring device for engineering surveying and mapping and a surveying and mapping method of the precise and durable handheld measuring device. And the outer walls of one sides of the two sliding openings are each fixedly connected with two first telescopic air cylinders, and the outer walls of one sides of the two first telescopic air cylinders located on one side are fixedly connected with the same sliding block. Through the arrangement of the dust suction cover, the dust suction hole, the dust suction pump, the telescopic hose and the dust collection box, when the measuring instrument is collected into the protection frame, a second telescopic rod is adjusted to enable the dust suction cover to move to an observation opening of the measuring instrument, then the dust suction pump is started, and dust around the observation opening is adsorbed through the dust suction hole in the dust suction cover on the telescopic hose; and then the dust is uniformly discharged into the dust collection box, so that dust at an observation opening of the placed measuring instrument can be effectively isolated, and the situation that the dust corrodes the measuring instrument, and the service life of the device is affected is prevented.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a precise and durable hand-held measuring device for engineering surveying and mapping and a surveying and mapping method thereof. Background technique [0002] Before carrying out large-scale project construction, surveying and mapping engineers must measure and draw topographic maps and provide other information before they can make decisions, plans, and designs; The construction of the project is carried out in strict accordance with the plan. Engineers mostly use measuring instruments when surveying and mapping. Measuring instruments have brought more convenience to the staff in construction operations, among which hand-held measuring instruments are used most. [0003] Most of the existing handheld measuring devices are exposed outside when they are not in use. The engineer does not protect the outside of the measuring instrument tightly enough du...
