Problems solved by technology

Due to the influence of the tension of the inverted floating body on the tension line body with the fatigue and temperature changes of the tension line body, and the possible inaccuracy in the processing of the inverted floating body itself, the inverted floating body may not be horizontal, resulting in the perpendicular to the inverted floating body. The connecting rod is not vertical, which affects the measurement accuracy of the inverted system

Abstract

The invention discloses a drooping-down buoyancy leveling device which aims at solving the problems that a drooping-down floating body is not horizontal in installation and measuring accuracy is affected. The drooping-down buoyancy leveling device comprises a drooping-down outer barrel and the drooping-down floating body arranged in the drooping-down outer barrel, wherein the drooping-down floating body is fixedly connected with a connection rod, a hollow passage is arranged in the connection rod, a drooping-down line penetrates through the hollow passage of the connection rod, and one end of the drooping-down line is fixedly connected at the top end of the connection rod. A leveling mechanism for adjusting the horizontal position of the drooping-down floating body is arranged at the top end of the drooping-down floating body. The drooping-down buoyancy leveling device can perform free adjusting on a leveling hammer on a leveling screw and can achieve the aim of leveling the drooping-down floating body through indicating of a circular level on the upper portion of the drooping-down floating body. The drooping-down buoyancy leveling device is reasonable in design, simple in structure, convenient to operate, accurate in balancing, few in installation parts, low in cost, convenient, flexible, high in working efficiency, good in effect and wide in application range.

Description

technical field [0001] The invention relates to a connection device used for installation of engineering safety monitoring instruments and equipment, and is especially suitable for installation, operation period maintenance and debugging of upside-down monitoring equipment for dam safety monitoring. Background technique [0002] Under the existing technical conditions, the general inverted floating body used for engineering safety monitoring does not have a level adjustment device, and only depends on the tension generated by the inverted floating body during installation and operation to make the inverted floating body reach the level. Due to the influence of the tension of the inverted floating body on the tension line body with the fatigue and temperature changes of the tension line body, and the possible inaccuracy in the processing of the inverted floating body itself, the inverted floating body may not be horizontal, resulting in the perpendicular to the inverted floati...
