Description
Technical Field
[0001] The utility model belongs to the technical field of measurement, in particular to a laser level tracker device used for elevation and level measurement. Background Art
[0002] The elevation values of each monitoring point on the top surface of the main dam, auxiliary dam, spillway and other building structures of the reservoir dam change with time in the vertical direction relative to the elevation value of the working base point. At the same time, they also have horizontal displacement changes, which require long-term monitoring.
[0003] The traditional observation method is to use precision optical leveling to establish a vertical displacement monitoring and control network through reference points, working base points, and displacement measurement points. This method is scientific and has reliable monitoring accuracy, but it still cannot get rid of manual observation and cannot meet the requirements of automated, all-weather, real-time, and unattended automatic monitoring. In addition, the horizontal displacement measurement accuracy is usually difficult to meet application requirements and difficult to transmit. Therefore, horizontal displacement positioning is usually achieved through a satellite positioning system. However, the measurement using a satellite positioning system is too complicated and the measurement cost is high. Therefore, in order to solve the common defects in the above-mentioned prior art, it is urgent to improve the existing elevation and level measurement technology and provide a laser level tracker device for elevation and level measurement. Utility Model Content
[0004] The purpose of the utility model is to provide a laser level tracker device with reasonable design, simple structure and capable of taking both elevation and horizontal measurements into account in view of the deficiencies in the prior art, so as to solve the problems existing in the prior art such as simultaneous automatic monitoring of the vertical and horizontal displacements of the dam.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A laser level tracker device for elevation and horizontal measurement, comprising a light source pier, a high-precision turntable, a leveling laser and a digital monitoring target. The laser level tracker device comprises a transmitting light source station and a receiving monitoring station. The transmitting light source station comprises a light source pier, a high-precision turntable, a protective component and a leveling laser. The receiving monitoring station comprises a monitoring pier, a high-precision turntable, a protective component and a digital monitoring target. The leveling laser in the transmitting light source station transmits a laser beam to the digital monitoring target in the receiving monitoring station. The digital monitoring target collects a laser beam spot image, thereby measuring the elevation and horizontal displacement changes of the receiving monitoring station relative to the transmitting light source station, thereby realizing automatic monitoring of elevation and horizontal deformation.
[0007] As a preferred embodiment, storage batteries are fixedly installed inside both the light source pier and the monitoring pier. Charging interfaces are inlaid and fixed along the outer edges of the upper ends of the light source pier and the monitoring pier. A baffle is provided inside the charging interface. One end of the baffle is adhesively bonded to the inner wall of the charging interface, and the baffle is made of rubber.
[0008] As a preferred embodiment, a liquid optical wedge is installed inside the level laser, and the digital monitoring target consists of an optical system and a monitoring camera.
[0009] As a preferred embodiment, positioning grooves are formed at the tops of both of the high-precision turntables. The positioning grooves include insertion slots and clamping grooves. The two insertion slots are symmetrically formed at the tops of the high-precision turntables. Clamping grooves are formed on the opposite sides of the two insertion slots, and the clamping grooves communicate with the insertion slots.
[0010] As a preferred embodiment, the protection component includes support rods, a protective cover, an observation window, limiting rods, a positioning frame, and springs. Support rods are symmetrically and fixedly connected to the bottom end of the protective cover. The protective cover is umbrella-shaped, and an observation window is inlaid and fixed in the middle of its top end. The observation window is made of transparent organic glass. Limiting rods are fixed inside the bottoms of the support rods. A positioning frame is slidably sleeved on the outer side of one end of the limiting rod, and a spring is sleeved on the outer side of the other end of the limiting rod.
[0011] As a preferred embodiment, the longitudinal section of the positioning frame is an inverted "concave" shape. The upper and lower ends of the positioning frame penetrate through the support rods and are slidably connected to them. The bottom of the positioning frame is provided with an inclined surface.
[0012] As a preferred embodiment, the bottom of the support rod is inserted into the high-precision turntable through the insertion slot, and the bottom end of the positioning frame is snap-fitted to the high-precision turntable through the clamping groove.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] In the solution of the present utility model:
[0015] A level laser based on a high-precision turntable is adopted. On the basis of re-measuring the elevation of the original surface deformation observation point, using the high-precision turntable as a reference, the automatic monitoring of the horizontal displacement and vertical displacement of the surface deformation observation point is realized at the same time. A laser beam is emitted from the level laser in the transmitting light source station to the digital monitoring target in the receiving monitoring station, and the digital monitoring target collects the laser beam spot image, so as to measure the elevation and horizontal displacement changes of the receiving monitoring station relative to the transmitting light source station, and realize the automatic monitoring of elevation and horizontal deformation;
[0016] The high-precision turntable drives the level laser to rotate, enabling front and rear views. The laser can be irradiated onto receiving monitoring stations in different directions, and the digital monitoring target can be rotated according to needs through another high-precision turntable to receive the light beam emitted by the level laser. During the monitoring process, the high-precision turntable is used for horizontal displacement monitoring, eliminating the need for a satellite positioning system, greatly reducing the system complexity and significantly reducing costs.
[0017] The umbrella-shaped protective cover can provide protection for the level laser and the digital monitoring target, playing a role in anti-collision and rain protection. And by squeezing the positioning frame, it slides and contracts towards the inside of the support rod. When the bottom of the positioning frame disengages from the card slot, the entire protective component can be removed from above the high-precision turntable, with quick installation and disassembly and easy operation.

At the same time, the rubber baffle 4 can cover and hide the charging interface 3 when it is idle to prevent impurities from entering.
[0030] On the basis of the above structure, a liquid optical wedge is installed in the leveling laser 7, and the digital monitoring target 8 is composed of an optical system and a monitoring camera.
[0031] In this embodiment, the liquid optical wedge installed in the leveling laser 7 can ensure that the leveling laser 7 can emit a horizontal laser line and irradiate it to the receiving monitoring station.
[0032] On the basis of the above structure, positioning grooves 9 are provided on the tops of the two high-precision turntables 5. The positioning grooves 9 include a slot 91 and a card slot 92. The two slots 91 are symmetrically provided on the tops of the high-precision turntables 5. Card slots 92 are provided on opposite sides of the two slots 91. The card slots 92 are connected to the slots 91.
[0033] In this embodiment, the positioning groove 9 is provided to facilitate quick disassembly and assembly of the protection assembly 6 on the top of the high-precision turntable 5 , which is easy to operate.
