Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the embodiments.

[0027] A portable downhole water metering device, such as Figures 1-3 The system includes a base 1, three adjusting screws 2 at the bottom of the base 1, a rectangular capacity tank 4 in the middle of the base 1, a circular level bubble 3 on the base 1 and located outside the rectangular capacity tank 4, a high level sensor 5 and a low level sensor 6 mounted on the outer wall of the rectangular capacity tank 4, a scale 7 on the outer wall of the rectangular capacity tank 4, and a processing unit 17 on the rectangular capacity tank 4. The scale 7 corresponds to the high level sensor 5 and the low level sensor 6. There are three adjusting screws 2, two on one side of the base and one on the opposite side, arranged in an equilateral triangle for adjusting the level of the base 1. The adjusting screws 2 can also be adjusting bolts.

[0028] like Figure 4The processing unit 17 is mainly used for control, display, and circuit connection. The processing unit 17 includes a control module 12, a first relay 13, a second relay 14, a display screen 15, and a power module 10. The power module 10 is provided with an external power module socket 11, which is connected to a mobile power supply 20. The control module 12 is connected to the first relay 13, the second relay 14, the display screen 15, and the power module 10. The high liquid level sensor 5 and the low liquid level sensor 6 are connected to the second relay 14 and the first relay 13 respectively through data transmission cables 8.

[0029] The rectangular capacity tank 4 is also provided with a water inlet / outlet 16 on its outer wall, and the water inlet / outlet 16 is connected to a water collection pipe.

[0030] like Figure 5 The water collection pipe includes a connecting pipe 19 connected to the water inlet / outlet 16 and a conical collector 18 connected to the connecting pipe 19. The conical collector 18 is matched with a corresponding water spray point 22 to be tested. Both the conical collector 18 and the connecting pipe 19 are made of rubber, and the rectangular capacity tank 4 is made of glass.

[0031] The display screen 15 is an LCD liquid crystal display screen or an LED display screen. The control module 12 can be a Siemens ET200, a microcontroller, or other controllers. All of these fall within the scope of existing technology. The control process and control content are also very common. The calculation and processing are also relatively basic division operations. The processing method is very simple. Therefore, the control module 12 is not the core of this patent.

[0032] Figures 1-3 In the rectangular capacity tank 4, the water inlet / outlet 16 and the scale 7 are located on opposite sides, such as the left and right sides. The high level sensor 5, the low level sensor 6, and the scale 7 are located on the same side of the rectangular capacity tank 4, such as the right side.

[0033] The rectangular capacity tank 4 can also have an opening at the top for faster water drainage.

[0034] In use, the connecting pipe 19 is connected to the water inlet / outlet 16, and the positive and negative terminals of the portable power supply 20 are connected to the positive and negative terminals of the power module external connector 11. The low liquid level sensor 6 is connected to the first relay 13 via the data transmission cable 8, and the first relay 13 is connected to the input port of the control module 12 via the data transmission cable 8. The output terminal of the control module 12 is connected to the display screen 15 via the data transmission cable 8. The high liquid level sensor 5 is connected to the second relay 14 via the data transmission cable 8, and the second relay 14 is connected to the input port of the control module 12 via the data transmission cable 8 (Note: In this embodiment, the control module 12 can be an ET200, which has multiple input ports and is not the same cable as the data transmission cables 8 of the high liquid level sensor 5 and the low liquid level sensor 6). The output terminal of the control module 12 is connected to the display screen 15 via the data transmission cable 8 (the output terminal can be the same output cable, controlled by the digital signal output by the control module 12).

[0035] Reference Figure 4 The diagram below shows the circuit connection of the device. The power module 10 outputs a DC voltage of 24V, and the components are connected in parallel.

[0036] Reference Figure 6 , Figure 7 When the device is in use, after the operator places the device in a stable position, adjust the three adjusting screws 2 of the base 1 to make the base 1 horizontal. Install the water collection pipe and use the cone collector 18 to collect water at the point to be measured (the water spray point 22). The device records the trigger time interval of the high liquid level sensor 5 and the low liquid level sensor 6, records the final time value, and calculates the water flow rate at the point based on the preset capacity (10L).

[0037] Cables used for data transmission are collectively referred to as data transmission cables (8), and cables used for power transmission are collectively referred to as circuit connection cables (9). (Note: Not individually labeled.)

[0038] The specific implementation method is as follows:

[0039] Preparations before use:

[0040] 1) Place the water metering device 21 in a stable position, adjust the state of the base 1 using the three adjusting bolts 2 on the base 1, and determine whether the base 1 is in a horizontal state by observing the position of the center bubble of the circular level bubble 3; when the base 1 is in a horizontal state, the bubble is located at the center of the circular level bubble 3.

[0041] 2) Connect the connecting pipe 18 at the lower end of the water collection pipe to the water inlet / outlet 16 tightly.

[0042] 3) Insert the mobile power supply 20 interface into the power module external connector 11 of the power module 10 to provide power to the device.

[0043] Work steps:

[0044] The operator holds the cone-shaped collector 18 at the top of the water collection pipe to collect all the water flowing from the test point 22. The water flows along the connecting pipe 18 of the water collection pipe into the water inlet / outlet 16 of the device and into the rectangular capacity tank 4. The water flow continues to rise. When the water level reaches the low level sensor 6, the first relay 13 is triggered, sending an electrical signal to the control module 12. The built-in timer in the control module 12 starts timing and converts it into a digital signal, which is then transmitted to the display screen 15 to show the time value. This continues until the water flow submerges the high level sensor 5, and the displayed value on the display screen 15 no longer changes. The operator records the final displayed value, unplugs the power supply 20 from the external connector 11 of the power module, unplugs the connecting pipe 19, releases all the water from the rectangular capacity tank 4, puts away the water collection pipe, and repeats the above steps to measure the water volume at the next location.

[0045] The water collection pipe consists of a conical collector 18 and a connecting pipe 19.

[0046] The connecting pipe 19 of the water collection pipe is made of rubber with a thickness of 2mm; the cone-shaped collector 18 is made of rubber with a thickness of 4mm, and its main function is to collect water flow.

[0047] Control module 12: Siemens ET200 DC24V, a commercially available product.

[0048] First relay 13 and second relay 14 model: RXM4AB2BD DC24V.

[0049] Power module 10: Aipu FA3-220SXXA2N3, output DC24V.

[0050] High liquid level sensor 5, low liquid level sensor 6: AT35-7-U6.

[0051] Display screen 15: M6202.

[0052] This device utilizes the high liquid level sensor 5 and the low liquid level sensor 6 to trigger the second relay 14 and the first relay 13 respectively. The second relay 14 and the first relay 13 send electrical signals to the control module 12. The control module 12 uses the soft timing function to record the time interval between the triggering of the low liquid level sensor 6 and the triggering of the high liquid level sensor 5. This allows for the accurate measurement of the time difference T between the high and low liquid level sensors for a fixed volume of water flow V (the fixed volume is set to 10L). The unit flow rate formula Q = V / T (unit: L / s) can be used to obtain the unit flow rate of water at the test point 22, which is then displayed on the display screen 15.

[0053] The above process is simple, convenient, and efficient, and can accurately measure the water flow at the location of the water infiltration, replacing the errors caused by traditional manual estimation, making the data real, reliable, and verifiable. It plays a very good role in understanding the regional hydrological conditions, provides effective technical support for safe production in mines, and has good practical value and application value.
