Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring devices, and in particular to a geographic information remote sensing measuring device with an anti-shake structure. Background Technology
[0002] Geographic information remote sensing measurement devices are key facilities for acquiring geospatial information using remote sensing technology. They are widely used in fields such as resource surveys, environmental monitoring, disaster assessment, and urban planning by detecting the electromagnetic radiation and laser reflection characteristics of objects. However, to improve the stability of the measurement, a pan-tilt unit is typically used for anti-shake purposes during device use. However, factors such as natural hand tremors from the operator, uneven ground causing bumps, and wind can all lead to vertical vibrations and impacts on the measuring device. These vibrations are directly transmitted to the laser measuring instrument, and the pan-tilt unit cannot buffer these vibrations, causing optical path deviation and measurement point jitter. This reduces the instantaneous accuracy and repeatability of the measurement data. Furthermore, once the pan-tilt unit is installed, its position cannot be adjusted. Different measurement scenarios and targets have diverse requirements for the working height and horizontal position of the laser measuring instrument, limiting the device's adaptability. This makes it difficult for the operator to quickly and accurately adjust the measuring instrument to the optimal observation position according to the terrain, obstacles, or specific measurement task requirements, affecting the efficiency and convenience of the measurement. Utility Model Content
[0003] The main objective of this invention is to provide a geographic information remote sensing measurement device with an anti-shake structure, which can effectively solve the technical problems raised in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A geographic information remote sensing measurement device with an anti-shake structure includes a mounting sleeve, a movable handle, and a laser measuring instrument. The movable handle is fixedly installed at the lower end of the mounting sleeve, and the laser measuring instrument is located in front of the mounting sleeve. A telescopic mounting rod is movably installed inside the mounting sleeve. A buffer guide rail structure is provided at the front end of the telescopic mounting rod. A mounting sleeve is slidably installed on the outer side of the buffer guide rail structure. A mounting connecting rod is fixedly installed at the front end of the mounting sleeve. An anti-shake gimbal is fixedly installed at the front end of the mounting connecting rod. A clamping plate is fixedly installed at the front end of the anti-shake gimbal. A mounting plate that fits over the laser measuring instrument is fixedly installed at the front end of the clamping plate.
[0005] As a further embodiment of this utility model, the telescopic mounting rod passes through the mounting sleeve rod, and the mounting sleeve rod is locked and fixed to the telescopic mounting rod by an upper screw.
[0006] As a further embodiment of this utility model, the buffer guide rail structure includes a lifting mounting sleeve, a guide rail rod, a mounting top plate, a damping buffer rod, and a support spring. The lifting mounting sleeve is fixedly installed at the front end of the telescopic mounting rod, the guide rail rod is movably installed inside the lifting mounting sleeve, the mounting top plate is fixedly installed at the upper end of the guide rail rod, the damping buffer rod is fixedly installed at the upper end of the telescopic mounting rod, and the support spring is sleeved on the outer side of the damping buffer rod.
[0007] As a further embodiment of this utility model, the guide rail rod moves up and down around the lifting mounting sleeve, and the upper end of the damping buffer rod is fixedly connected to the mounting top plate.
[0008] As a further embodiment of this utility model, the mounting sleeve is slidably mounted on the outside of the guide rail rod, and a locking knob is threadedly mounted on the top of the mounting sleeve, with the end of the locking knob resting on the outside of the guide rail rod.
[0009] As a further embodiment of this utility model, the anti-shake gimbal is located behind the laser measuring instrument, and a measuring lens is provided in front of the laser measuring instrument.
[0010] Compared with the prior art, this utility model has the following beneficial effects: Through the design of the buffer guide rail structure, when the device is subjected to vertical vibration or impact, the guide rail rod can move up and down in the lifting mounting sleeve. The damping buffer rod provides damping force, and the support spring provides elastic restoring force, which can effectively absorb and attenuate vertical vibration energy, significantly reduce the vibration amplitude transmitted to the front laser measuring instrument, and prevent the measuring lens from shaking due to factors such as hand tremors, uneven ground, or wind, thereby greatly improving the stability and accuracy of laser measurement. Combined with the stability of the anti-shake gimbal, the anti-shake effect of the measurement is maximized. By sliding the telescopic mounting rod within the mounting sleeve, the overall front-to-back position of the laser measuring instrument can be adjusted. The mounting sleeve slides up and down along the outside of the guide rail to adjust the overall working height of the laser measuring instrument. This allows the operator to flexibly and accurately adjust the working height and horizontal position of the laser measuring instrument according to the site environment and measurement needs, greatly enhancing the adaptability and ease of operation of the device.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] like Figures 1-4 As shown, a geographic information remote sensing measurement device with an image stabilization structure is described. Please refer to the following document for details. Figures 1-4 The system includes a mounting sleeve 1, a movable handle 2, and a laser measuring instrument 16. The movable handle 2 is fixedly installed at the lower end of the mounting sleeve 1, and the laser measuring instrument 16 is located in front of the mounting sleeve 1. A telescopic mounting rod 3 is movably installed inside the mounting sleeve 1. A buffer guide rail structure 4 is provided at the front end of the telescopic mounting rod 3. A mounting sleeve 10 is slidably installed on the outer side of the buffer guide rail structure 4. A mounting connecting rod 12 is fixedly installed at the front end of the mounting sleeve 10. A stabilizing gimbal 13 is fixedly installed at the front end of the mounting connecting rod 12. A clamping plate 14 is fixedly installed at the front end of the stabilizing gimbal 13. A mounting plate 15, which is fitted onto the outer side of the laser measuring instrument 16, is fixedly installed at the front end of the clamping plate 14.
[0015] Please refer to this carefully. Figures 1-3 The telescopic mounting rod 3 passes through the mounting sleeve rod 1, and the mounting sleeve rod 1 is locked and fixed to the telescopic mounting rod 3 by the upper screw.
[0016] Specifically, the overall front-to-back position of the front laser measuring instrument 16 is adjusted by extending and retracting the telescopic mounting rod 3 within the mounting sleeve rod 1, and then the screws are tightened to fix it.

[0019] Specifically, the vertical vibration causes the guide rod 6 to move up and down within the lifting mounting sleeve 5. The guide rod 6 retracts by pushing the damping buffer rod 8 and the support spring 9 through the mounting top plate 7. The retraction of the damping buffer rod 8 provides a buffering effect, reducing the impact of vibration on the laser measuring instrument 16.
[0020] Please refer to this carefully. Figures 1-4 The mounting sleeve 10 is slidably mounted on the outside of the guide rail rod 6. A locking knob 11 is threaded on the top of the mounting sleeve 10, and the end of the locking knob 11 rests on the outside of the guide rail rod 6.
