Engineering survey level gauge with bubble type automatic leveling function

Abstract

The invention discloses an engineering survey level gauge with a bubble type automatic leveling function. The engineering survey level gauge comprises an automatic leveling device, a bubble adjustmentdevice, a level gauge main body, a lens, a compensator, a collective collimator, a focal length adjustment knob, a target telescope and a rotating seat. The level gauge is leveled by the automatic leveling device. In the leveling process, a balance device is used for synchronously driving rollers to deviate according to the topographic deflection. Power is switched on through contact with a contact, and a horizontal adjustment plate is adjusted in cooperation with a small motor and a lifting rod, thereby avoiding the need for manual readjustment and re-calibration of the level gauge when thelevel gauge inclines on uneven construction ground, thereby realizing automatic adjustment of the level gauge. A controller controls the small motor by means of the current change caused by the movement of horizontal bubbles in a conductive water column through the bubble adjustment device, thereby avoiding the phenomenon of error caused by the deviation of the level gauge during leveling, and effectively improving the measuring accuracy and efficiency of the level gauge.

Description

technical field [0001] The invention relates to the field of engineering surveying, in particular to a bubble-type automatic leveling leveling instrument for engineering surveying. Background technique [0002] The level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. It is widely used in civil engineering and geological surveying fields. In actual measurement operations, due to the soft ground or the limitation of the measurement space, the support frame of the level cannot be used very Maintain the stability of the level well and make it tilt, which will affect the measurement accuracy of the level. At present, the existing spirit level has the following disadvantages: [0003] When the construction ground is muddy or sandy, often due to the soft ground, the force on the support legs of the level gauge is different, causing one of the support legs to collapse, causing the level to tilt, and it...

Problems solved by technology

[0003] When the construction ground is muddy or sandy, often due to the soft ground, the force on the support legs of the level gauge is different, causing one of the support legs to collapse, causing the level to tilt, and it is necessary to adjust and proofread it again, which is cumbersome to operate , time-consuming and labor-intensive, and it is easy to shift during adjustment, which greatly affects the measurement accuracy and measurement efficiency of the level
