Detailed Description
To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.
As shown in fig. 1, the hydraulic engineering water level monitoring device provided by the utility model comprises: a pressure monitoring cavity 110, a water storage pipe 130, an information processing module 140 and a monitoring element 120.
One end of the water storage pipe 130 is communicated with the pressure monitoring cavity 110, and the other end of the water storage pipe 130 is used for being arranged below the monitored water surface; the monitoring element 120 is disposed inside the pressure monitoring chamber 110, and is used for monitoring the pressure inside the pressure monitoring chamber 110 when the water storage pipe 130 stores water; the information processing module 140 is communicatively connected to the monitoring element 120, and is configured to receive the pressure value from the monitoring element 120, and calculate the water level height of the current monitored water surface according to the pressure value.
Specifically, referring to fig. 2, when monitoring the water level, the other end of the water storage tube 130 is placed below the monitored water level, and a certain amount of water is stored in the water storage tube 130, and it is ensured that the height of the water level in the water storage tube is absolutely higher than the height of the water level of the monitored water level.
In the above case, there is a pressure difference between the pressure P1 inside the pressure monitoring chamber 110 and the atmospheric pressure outside; and the pressure difference satisfies the following relationship:
P-P1＝(M*g)/S； (1)
wherein M is the mass of water distributed on the part of the water storage pipe higher than the water level, g is the gravity acceleration, and S is the cross-sectional area of the water storage pipe;
M*g＝ρ*V*g＝ρ*h*S*g (2)
wherein rho represents the density of water, V represents the volume of the water in the water storage pipe which is higher than the water level surface, and h represents the height of the water in the water storage pipe which is higher than the water level surface.
The following can be obtained from the above formula (2):
P-P1＝(ρ*h*S*g)/S＝ρ*h*g； (3)
thus, the following can be obtained:
h＝(P-P1)/(ρ*g) (4)
in equation (4), P, ρ, g are known constants at fixed geographic locations and environments; therefore, the height h of the water diversion of the water storage pipe higher than the water level surface can be obtained by calculating according to the formula (4) only by measuring the pressure P1 in the pressure monitoring cavity 110; the height of the current water level can be measured through further conversion.
Specifically, by monitoring the pressure P1 inside the pressure monitoring cavity 110 and sending the monitored pressure to the information processing module 140, the information processing module 140 can accurately calculate the water level height of the detected water surface according to the received pressure value and the above equation (4).
In this embodiment, when monitoring the water level, the other end of the water storage tube 130 is placed below the monitored water surface, the pressure inside the pressure monitoring cavity 110 is monitored, the monitored pressure is sent to the information processing module 140, and then the information processing module 140 can accurately calculate the water level height value of the detected water surface according to the received pressure value.
It can be understood that in the above equation (4), when the pressure change inside the pressure monitoring chamber 110 is ignored, the change in the volume of the gas inside the pressure monitoring chamber 110 and inside the water storage pipe is small (the change is small, and in the case that the height h of the water storage pipe above the water level is small, the change is negligible).
In order to solve the above problem, a correction curve may be obtained by actually measuring the height h of the water in the water storage pipe higher than the water level portion and the pressure P1 inside the pressure monitoring cavity 110, and after the information processing module 140 calculates h according to the above equation (4), the calculated value may be corrected according to the correction curve. Thereby making the final converted water level height more accurate.

Further, the monitoring element 120 further includes a temperature detecting unit, which is configured to monitor a temperature inside the pressure monitoring cavity; the wireless sending unit is also used for sending the value of the temperature in the pressure monitoring cavity to the information processing module.
Specifically, since the pressure and volume of the gas are related to the temperature, when the pressure and the amount of the gas are constant, the volume increases as the temperature increases; therefore, the accuracy of the above equation (4) is affected by the temperature variation; therefore, in order to improve the accuracy of the finally measured water level, a temperature detecting unit may be disposed on or linked to the monitoring element 120 to detect the temperature inside the pressure monitoring cavity, and then the detected temperature is transmitted to the information processing module 140 through the wireless transmitting unit, and the information processing module 140 corrects the calculated value of the above equation (4) according to the received temperature value. Thereby making the resulting water level height more accurate.
In an optional implementation manner, the information processing module 140 further includes a display unit, and the display unit is configured to display the water level height of the monitored water surface.
In an alternative embodiment, the information processing module 140 further comprises an alarm unit for giving an alarm if the water level of the monitored water surface is greater than a threshold value.
