[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1

[0023] like Figure 1As shown, an automatic laser leveling displacement monitoring device includes: a water tank 1, a data processing terminal 2, and multiple water level displacement laser measuring devices 3. One of the water level displacement laser measuring devices 3 is installed with the water tank 1 at a position where the ground elevation remains constant as a measurement base point. The other water level displacement laser measuring devices 3 are installed at monitoring points, i.e., monitoring points where the elevation changes. The specific number of water level displacement laser measuring devices 3 is determined according to the actual monitoring needs. Only two are shown in the figure, which does not mean that there are only two water level displacement laser measuring devices 3. There can also be three, four, five, or other numbers.

[0024] Water tank 1 is connected to water level displacement laser measuring device 3, which is located at a constant ground elevation, through level tube 4. Water level displacement laser measuring device 3, which is located at a constant ground elevation, is connected in series with other water level displacement laser measuring devices 3 through level tube 4. Water tank 1 is used to supply water to water level displacement laser measuring device 3 and provide a stable level surface. Water level displacement laser measuring device 3 is electrically connected to data processing terminal 2.

[0025] The principle is to use the principle of communicating vessels to ensure that the water level elevation in all water level displacement laser measuring devices 3 is consistent with the water surface elevation in water tank 1. The water level displacement laser measuring device 3 installed at the monitoring point is used to collect the internal water level change signal. Then, the water level displacement laser measuring device 3 transmits the measurement signal to the data processing terminal 2 through the communication line. The data processing terminal 2 processes the signal to feed back the elevation change information of the monitoring location.

[0026] Example 2

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0028] The water level displacement laser measuring device 3 includes: a level cup 310 and a top cover 320. The top cover 320 covers the mouth of the level cup 310. The bottom of the level cup 310 is provided with a water inlet 311 for connecting to the level tube 4 and a first water outlet 312. A reflector 330 is arranged in the level cup 310, which moves up and down according to the change of the liquid level inside. A laser emitting device 340 is fixed on the top cover 320. The laser emitting device 340 is used to emit laser light towards the reflector 330, that is, to emit a laser beam for measuring distance. The laser receiver 350 is bolted to the top cover 320. A laser receiver 350 is fixed on the top cover 320. The laser receiver 350 is used to receive the laser reflected by the reflector 330. The laser receiver 350 is bolted to the top cover 320. Both the laser emitter 340 and the laser receiver 350 adopt existing technology. The laser emitter 340 is electrically connected to the data processing terminal 2, and the laser receiver 350 is electrically connected to the data processing terminal 2. The bottom of the water tank 1 is provided with a second water outlet 110 for connecting the level tube 4.

[0029] The second water outlet 110 at the bottom of water tank 1 is connected to the water inlet 311 of the level cup 310 in the water level displacement laser measuring device 3, which is at a constant ground elevation, through a level tube 4. Similarly, the first water outlet 312 of the level cup 310 in the water level displacement laser measuring device 3 is connected to the water inlet 311 of the level cup 310 in another water level displacement laser measuring device 3, through a level tube 4. Likewise, the first water outlet 312 of the level cup 310 in one water level displacement laser measuring device 3 is connected to the water inlet 311 of the level cup 310 in the next water level displacement laser measuring device 3, through a level tube 4. By analogy, all water level displacement laser measuring devices 3 are connected in series through level tubes 4. The first water outlet 312 of the last water level displacement laser measuring device 3 is sealed, and the water level in the level cup 310 can be kept consistent with the water level in the water tank 1 according to the principle of communicating vessels. When the liquid level in the level cup 310 changes, such as falling, the reflector 330 will fall accordingly. The distance between the reflector 330 and the laser emitting device 340 and the laser receiving device 350 changes. The time difference between laser emission and laser reception is analyzed by the data processing terminal 2 to calculate the change in liquid level displacement, thereby obtaining the change in elevation of the monitored part.

[0030] Furthermore, the inner surface of the leveling cup 310 is coated with black light-absorbing material, and the inner surface of the top cover 320 is also coated with black light-absorbing material, which can reduce the error caused by laser scattering.

[0031] The outlet of the last water level displacement laser measuring device 3 is sealed using methods such as soft plugs and caps.

[0032] Example 3

[0033] like Figure 3 As shown, this embodiment is a further improvement on embodiment 2, as detailed below:

[0034] The laser emitting device 340 should have a power that meets safety standards, as well as high stability and directionality. The laser divergence angle should be small to ensure the accuracy and distance of the measurement. In this embodiment, the laser wavelength emitted by the laser emitting device 340 is 635nm to 905nm.

[0035] The laser receiver 350 can receive the reflected laser signal. Preferably, the laser receiver 350 should have high sensitivity and be able to accurately capture weak reflected light signals. In order to reduce external interference, narrowband filters and other technologies can be used to improve the signal-to-noise ratio.

[0036] Example 4

[0037] like Figure 1 As shown, this embodiment is a further improvement on embodiment 2, 3, or 4, as detailed below:

[0038] The water level displacement laser measuring device 3 located at the monitoring point is fixed with bolts, which is convenient to fix and has good stability.

[0039] Example 5

[0040] like Figure 4 As shown, this embodiment is a further improvement on any one of embodiments 2 to 4, as detailed below:

[0041] The water tank 1 is equipped with an overflow port 120. The water tank 1 is connected to an external water source 5, which can supply water to the water tank 1. Excess water in the water tank 1 can be discharged through the overflow port 120.

[0042] Example 6

[0043] like Figure 1 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below:

[0044] Data processing terminal 2 uses a computer, but other existing controllers are also possible; the common computer is just an example here.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
