Description

MONITORING DEVICE AND SYSTEM FOR CALCULATING ELECTRIC WATER REPLACEMENT COEFFICIENT
TECHNICAL FIELD The invention relates to underground water supervision. More specifically, the present invention relates to a monitoring device and a system for calculating electric water replacement coeffi- cient.
BACKGROUND ART The electric water replacement method is a method for calcu- lating and counting groundwater mining quantity, and the main principle of the method is that a conversion coefficient between groundwater mining quantity and power consumption of water-lifting facilities is obtained by testing the electric water replacement coefficient in a certain area. Then the total amount of groundwa- ter mining quantity in this area is calculated by using the sta- tistical data of electric guantity used for pumping in this area. This method is applicable to the areas without complete groundwa- ter mining quantity metering facilities, and is often applied to the concentrated agricultural irrigation areas in northern China. One of the key steps in the application of the electric water replacement method is to carry out an electric water replacement coefficient determination test, and the test procedure is general- ly as follows: 1, a water quantity measurement facility (commonly used portable ultrasonic flowmeter) is added on the tested pumping well, and the initial reading of the measurement facility is rec- orded; 2, the initial reading of the electric quantity metering facilities matched with water wells is recorded; 3, the pump is started to pump water and, according to a certain time interval, the readings of water quantity and electric quantity metering fa- cilities in the pumping process are recorded simultaneously; 4, the electric water replacement coefficient is calculated and ob- tained according to the recorded data, the calculation formula is obtained as follows: T.=W/E. In the formula, T. is the electric water replacement coefficient (unit: m’/kW:h); W is water output of the water pump in time period t (unit: m’); and E is power consump- tion of water pump in time period t (unit: kW-h).
When pumping, the groundwater level gradually decreases from a static water level to a stable dynamic water level. In this pro- cess, the instantaneous electric water replacement coefficient at each moment is different (the decrease of water level leads to the increase of the gravity barrier to be overcome for lifting unit water quantity and the increase of the electric quantity con- sumed). Therefore, the frequency of reading records of water quan- tity and electric quantity metering data is closely related to the calculation accuracy of electric water replacement coefficient. The higher the frequency is, the higher the calculation accuracy is. Under the current test conditions, the recording of the read- ings of metering facilities is basically done manually. It takes several hours to tens of hours for a single test to determine the electric water replacement coefficient. The manual recording meth- od requires the test personnel to keep standing on the test site for a long time, which not only consumes a lot of time and energy, but also easily causes errors and affects the test accuracy. In addition, the manual recording method is difficult to achieve con- tinuous high-frequency recording for a long time period (such as maintaining the recording frequency once per minute for several hours), and the space for improving the test accuracy is limited.
Therefore, there is a need for a solution that overcomes the above-mentioned drawbacks.

In order for the endoscopic camera 3 to take data vide- os of the electric quantity metering device 2 and the water guan- tity metering device 9 more stably, the position of the endoscopic camera 3 needs to be fixed. Specifically, the camera 3 is inserted from the lower part of the elbow pipe 5, the camera 3 is clamped on an upper end of the elbow pipe 5 via the sleeve plug 6, the el- bow pipe 5 is bent in a manner capable of aligning the electric quantity metering device 2 and the water quantity metering device 9, the lower part of the elbow pipe 5 is detachably connected to the fixture 7, and the fixture 7 is detachably connected to an electric pole 1 and a pipeline 8 on which the electric quantity metering device 2 and the water quantity metering device 9 are mounted, thereby fixing the endoscope camera 3 in front of the electric quantity metering device 2 and the water quantity meter- ing device 9. It can be seen that this embodiment has a simple structure and is easy to be installed, and can replace the manual recording of the electric quantity metering device 2 and the water quantity metering device 9, so as to provide a support for the im- plementation of the electric water replacement method and improve the accuracy of the test for measuring electric water replacement coefficient.
In other embodiments, the elbow pipe 5 is comprised of an up- per curved section and a lower straight section, the lower straight section being detachably connected to the fixture 7, and the upper curved section is used to enable the camera 3 to perform photographing at a certain distance from the electric quantity me- tering device 2 and the water quantity metering device 9, and also to make the camera 3 difficult to slide out.

For example, once in 10 seconds: (water quantity me- tering data at the moment of 10s - water quantity metering data at the moment of 0)/{electric quantity metering data at the moment of 10s - electric quantity metering data at the moment of 0) = the electric water replacement coefficient in the period of 0-10 sec- onds; (water quantity metering data at 20s - water quantity meter- ing data at 10s)/{electric quantity metering data at 20s - elec-
tric quantity metering data at 10s) = the electric water replace- ment coefficient in the period of 10-20 seconds.
