Description

Static level cable-stayed bridge monitoring device based on Beidou positioning Technical Field The utility model relates to the technical field of monitoring, in particular to a cable-stayed bridge monitoring device of a static level based on Beidou positioning. Background A static level is a precision instrument that measures the difference in height and its variation. The automatic monitoring system is mainly used for monitoring vertical displacement and inclination of pipe galleries, dams, nuclear power plants, high-rise buildings, foundation pits, tunnels, bridges, subways and the like, the static leveling instrument is generally installed on a measuring pier of the same height of a measured object or on the same height of the wall of the measured object, automatic data acquisition is realized through built-in single-machine version acquisition software of a field acquisition box and stored in a field acquisition system, and the data are connected with the Internet through wired or wireless communication and then transmitted to background network version software, so that automatic observation is realized. The current hydrostatic level is generally installed in pier lower position department, detects subsidence through detecting inside water pressure, but the pier top is the bridge floor generally, and this can influence the location of use big dipper satellite to the level, causes the location inaccurate, and then has influenced the normal work of equipment. Disclosure of utility model Based on the above, the utility model aims to provide the static level cable-stayed bridge monitoring device based on Beidou positioning, so as to solve the technical problem that the bridge deck is shielded and the positioning of the level by using the Beidou satellite is affected. In order to achieve the purpose, the technical scheme is that the cable-stayed bridge monitoring device of the static level based on Beidou positioning comprises the static level, wherein the bottom of the static level is fixedly connected with a support, the bottom of the support is rotationally connected with a supporting rod, the front side of the support is fixedly connected with a cross rod through a connecting piece, the front side of the support is provided with a camera, the top of one side of the cross rod is fixedly connected with a graduated scale, one end of the cross rod is rotationally connected with a transmitting mechanism, the transmitting mechanism comprises a mounting frame, and one side of the mounting frame is fixedly connected with a signal transceiver. Through adopting above-mentioned technical scheme, the fixed connection of hydrostatic level gauge and support ensures water pressure sensor direct contact pier, and real-time detection subsides the change, and the bracing piece is connected with the rotation of support and is permitted nimble adjustment signal transceiver's extending direction, avoids the bridge floor to shelter from, ensures the high accuracy of big dipper signal and receives. Further, the emission mechanism further comprises a balancing weight, a mounting plate and a laser emitter, the bottom of the mounting frame is fixedly connected with the balancing weight, the top of the mounting frame is connected with two sides of the mounting plate in an inserting mode, and the top of the mounting plate is fixedly connected with the outer wall of the laser emitter. Through adopting above-mentioned technical scheme, the balancing weight of emission mechanism makes the mounting bracket remain perpendicular throughout through gravity effect, ensures laser emitter's laser beam and ground parallel, forms stable horizontal datum line, avoids the measuring error that leads to because of the equipment slope. Further, the connecting piece passes through bolt and support fixed connection, and the other end fixed connection of connecting piece and horizontal pole, the one end and the horizontal pole middle part fixed connection of bracing piece, the front end and the camera of support peg graft mutually, the bottom of scale and the top fixed connection of connecting piece. Through adopting above-mentioned technical scheme, the connecting piece passes through the bolt to be fixed with the support, ensures the rigid connection of horizontal pole and support, prevents to become flexible because of the structure that bridge vibration leads to, and the horizontal pole middle part forms triangle-shaped bearing structure with the fixed connection of bracing piece, reinforcing whole anti wind load and mechanical deformation ability. Further, the support is L-shaped structure, and the bolt hole has all been seted up at L shape both ends. Through adopting above-mentioned technical scheme, the L-shaped structure of support realizes fixed with the two points of pier through the bolt hole at both ends, reinforcing installation stability, and the slope that the single-point is fixed to be led to is avoided or the risk that drops.
