Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy surveying and mapping, and particularly relates to a water conservancy surveying and mapping device and method. BACKGROUND

[0002] A dam is mainly used for flood control, and vertical deformation of the dam occurs under the action of self-weight load. In order to ensure the overall safety of the dam, the horizontal and settlement displacement of the dam need to be monitored to determine whether the dam has hidden dangers. The monitoring process usually uses a surveying and mapping instrument to record the position of a reference point placed on the dam to determine whether the dam has settlement.

[0003] At present, dam settlement monitoring is usually carried out periodically using a portable surveying and mapping instrument. However, the surveying and mapping instrument is a precision instrument, and long-term fixation of the surveying and mapping instrument on one side of the dam will cause the surveying and mapping instrument to be eroded by rain and snow in harsh weather, resulting in a decline in the monitoring effect of the surveying and mapping instrument or even damage to the surveying and mapping instrument.

[0004] To solve this defect, the utility model with publication number CN221725202U discloses a water conservancy dam settlement detection device, which comprises a stand, a mounting box and a surveying and mapping instrument. The mounting box is fixedly connected to the top end of the stand, and the surveying and mapping instrument is arranged in the mounting box. One side of the mounting box is provided with an expandable corrugated shielding cover, and the top plate of the mounting box is provided with a rotating rotary seat. The mounting box can protect the surveying and mapping instrument. When the surveying and mapping instrument is monitoring, the motor is in a non-starting and non-self-locking state. Under the elastic force of the two side tension springs, the corrugated shielding cover is in a folded state, which facilitates the monitoring of the surveying and mapping instrument on the dam. When the surveying and mapping instrument is not monitoring, the motor is started, and the motor drives the winding seat to rotate, thereby winding the two side tension ropes of the winding seat, so that the corrugated shielding cover is expanded under the pulling of the two tension ropes. Then, the motor is self-locked, so that the corrugated shielding cover can shield and protect the surveying and mapping instrument.

[0005] However, the above-mentioned disclosed technology has many defects. Firstly, the device claims to protect the surveying and mapping instrument from rain and snow erosion by the corrugated cover, but the most critical period of settlement monitoring is the heavy rain / snow melting period (at this time, the load on the dam is the largest), and closing the protective cover will cause the surveying and mapping instrument to be unable to work, which is contrary to the fundamental purpose of settlement monitoring. Secondly, the protective cover expansion mechanism has technical regression, and the tension rope+winding seat+tension spring scheme has poor reliability: the tension rope is prone to elongation / breakage in a humid environment, and the cantilever structure of the expanded protective cover has a large wind area, which may tear the cover body in a strong wind environment.

[0006] In view of the above defects, it is necessary to further improve the structure. SUMMARY

[0007] The application aims to provide a water conservancy surveying and mapping device and method to solve the problems in the prior art, avoid the problem of reduced monitoring accuracy or even damage of the monitoring assembly caused by wind and snow erosion due to long-time installation of the monitoring assembly outdoors, and realize long-time accurate monitoring of the dam.

A water conservancy surveying and mapping detection method based on the water conservancy surveying and mapping detection device of claim 9, characterized in that, It comprises the following steps: S1, device installation and baseline measurement: install the base at the dam monitoring point, obtain the initial coordinates P0 through the monitoring assembly; install another water conservancy surveying and mapping detection device at the reference point, and record the initial elevation difference ΔH0; S2, rain monitoring optimization: when the rainfall sensor detects that the rainfall intensity exceeds the set value, the controller applies a pulse voltage to the electrochromic glass; the camera analyzes the raindrop coverage rate on the electrochromic glass in real time, and if the raindrop coverage rate exceeds the set value, the raindrops on the electrochromic glass are blown dry by the blowing bar and the first electric telescopic rod; S3, intelligent cleaning and maintenance: a) Regular maintenance: regular maintenance interval is set to automatically execute for a certain period of time, the water pump extracts the solution in the water tank, and sprays through the water outlet on the water spraying bar; after the delay is set for a certain period of time, the fan inhales air to form hot air through the electric heating net, and blows out through the blowing port on the blowing bar; b) Dynamic maintenance: when the camera detects that the visible light band transmittance of the electrochromic glass is less than the set value, the electrochromic glass is cleaned by the water spraying bar and the first electric telescopic rod; S4, settlement adaptive calibration: the altitude sensor collects elevation data every interval set time; if the elevation change δh is greater than the set value for a continuous set number of times, the second electric telescopic rod is started to compensate the height of the monitoring box: Compensation amount ΔL=K·δh; Wherein K is the deformation coefficient of dam material, the value range is 0.6≤K≤0.8; After stretching, the elevation difference ΔHt with the reference point is verified again to ensure that |ΔHt-ΔH0|≤0.05mm.
