Description

Technical Field

[0001] This utility model relates to the field of actual well depth monitoring technology, and in particular to a well depth monitoring device for water level in open-pit mine dewatering wells. Background Technology

[0002] During open-pit mining, groundwater dewatering is a crucial step in ensuring the safe and efficient operation of mining. Due to the complex geological conditions in open-pit mining areas, the groundwater level and actual well depth will change dynamically with factors such as mining progress, seasonal changes, and geological tectonic activity. If the water level and actual well depth information of the open-pit mine dewatering well cannot be obtained in real time and accurately, it may lead to a series of serious problems.

[0003] Currently, traditional methods for monitoring the water level and actual depth of open-pit mine dewatering wells have many limitations. Open-pit mine dewatering wells often contain a large amount of impurities such as sand and gravel. Existing monitoring equipment lacks an effective filtration mechanism, and impurities can easily enter the equipment, causing wear, blockage, or even damage to key components such as monitoring sensors. This seriously affects the accuracy of monitoring data and the reliability and service life of the equipment, leading to frequent interruptions in monitoring work and increasing maintenance costs and downtime.

[0004] In conclusion, developing a high-efficiency filtration device for monitoring the actual well depth and water level of open-pit mine dewatering wells is of great significance for improving the safety and efficiency of open-pit mining and reducing production costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for monitoring the water level and depth of open-pit mine dewatering wells.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water level and well depth monitoring device for dewatering wells in open-pit mines includes a monitoring component and a drainage component. The monitoring component includes a support plate and a housing. The support plate is welded to the inner wall of the housing. A water level monitoring module, a power module, an edge computing and communication module, and a well depth monitoring module are respectively installed on the top of the support plate. The water level monitoring module, power module, edge computing and communication module, and well depth monitoring module are electrically connected to each other. An airbag-type fixing component is installed on the top of the housing. An ultrasonic component and a water pressure sensor are respectively fixed on the bottom of the support plate. A filter screen is fixed on the bottom of the housing.

[0008] As a further embodiment of this utility model: the drainage assembly includes a submersible pump and a hose, with the hose fixed to the output end of the submersible pump.

[0009] As a further embodiment of this utility model: the airbag-type fixing component includes a cylinder, an electric telescopic rod, and a mounting frame. The mounting frame is welded to the inner wall of the cylinder, and the electric telescopic rod is fixed to the top outer wall of the mounting frame.

[0010] As a further embodiment of this utility model: a connecting air pipe is fixed to the outer circumference of the cylinder by welding, and an annular seat is fixed to the outer wall of the connecting air pipe, and an annular airbag is installed on the inner wall of the annular seat, and the annular airbag and one end of the connecting air pipe are connected by a connector.

[0011] As a further embodiment of this utility model: the output end of the electric telescopic rod is fixed with a piston rod by a pin, and a piston plate is fixed at the bottom of the piston rod; a piston cylinder is welded to the end of the connecting air pipe away from the annular airbag, and the piston cylinder and the piston plate are movably connected.

[0014] Compared with the prior art, this utility model provides a device for monitoring the water level and well depth of open-pit mine dewatering wells, which has the following beneficial effects:

[0015] 1. Through the synergistic effect of the water pressure sensor and the ultrasonic component, the device can simultaneously achieve accurate measurement of water level and actual well depth. The water pressure sensor calculates the water level based on the principle of hydrostatic pressure, while the ultrasonic component determines the distance to the top of the gravel by measuring the time difference between sound wave emission and reception, and then calculates the actual well depth, ensuring the comprehensiveness and accuracy of the monitoring data.

[0016] 2. The airbag-type fixing component uses an electric telescopic rod to drive the piston plate to compress the gas pre-stored in the piston cylinder, causing the annular airbag to expand and fit tightly against the well wall, providing stable support for the device. This fixing mechanism can adapt to open-pit mine dewatering wells with different well diameters and well wall conditions, ensuring stability during the monitoring process.

[0017] 3. The drainage system, through the synergistic action of the submersible pump and hose, can easily achieve drainage of the dewatering wells in open-pit mines. After the submersible pump is started, the well water is drawn in and then discharged from the wellhead through the submersible pump and hose. This drainage method is simple to operate and highly efficient, and can meet the drainage needs of the dewatering wells in open-pit mines.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] A device for monitoring water level and well depth in open-pit mine dewatering wells, in order to improve monitoring effectiveness, such as... Figures 1 to 5As shown, the system includes a monitoring component and a drainage component. The monitoring component includes a support plate 22 and a housing 9. The support plate 22 is welded to the inner wall of the housing 9. A water level monitoring module 17, a power module 18, an edge computing and communication module 19, and a well depth monitoring module 21 are respectively installed on the top of the support plate 22. The water level monitoring module 17, the power module 18, the edge computing and communication module 19, and the well depth monitoring module 21 are electrically connected. An airbag-type fixing component is installed on the top of the housing 9. An ultrasonic component 20 and a water pressure sensor 6 are respectively fixed on the bottom of the support plate 22. A filter screen 10 is fixed on the bottom of the housing 9.

[0028] When it is necessary to monitor the water level and actual well depth, the housing 9 moves the water pressure sensor 6 and the ultrasonic component 20 to a certain depth. The water level and actual well depth can then be monitored using the water pressure sensor 6 and the ultrasonic component 20. The specific monitoring principle is as follows:

[0029] When measuring water level using water pressure sensor 6, the water pressure sensor 6 measures the net water pressure P, and the water level is calculated using the formula:

[0030]

[0031] Where ρ is the liquid density and g is the gravitational acceleration;

[0032] When it is necessary to use the ultrasonic component 20 to measure the actual well depth (the distance from the wellhead to the top surface of the gravel at the bottom of the well), the ultrasonic component 20 measures the time difference t between transmission and reception, and calculates the distance from the ultrasonic component 20 to the top surface of the gravel at the bottom of the well:

[0033]

[0034] Where v is the speed of sound in water, the actual well depth is:

[0035] H 井深 =H 泵 +H

[0036] Filter screen 10 can be used to filter sand and gravel in open-pit mine dewatering wells;

[0037] The water level monitoring module 17 is connected to the water pressure sensor 6 through the filter 10, and transmits the monitored water pressure to the edge computing and communication module 19; the power module 18 supplies power to the water level monitoring module 17, the edge computing and communication module 19, and the well depth monitoring module 21; the edge computing and communication module 19 obtains basic data such as monitoring frequency and sensor installation location from the host computer; it obtains the water pressure P and time difference t used to calculate the water level and actual well depth from the water level monitoring module 17 and the well depth monitoring module 21 at a certain frequency, performs the calculation of water level and actual well depth, and communicates the calculation results with the host computer; the well depth monitoring module 21 monitors the ultrasonic wave transmission-reception time difference t and transmits the monitored time difference t to the edge computing and communication module 19.

[0038] The drainage assembly includes a submersible pump 4 and a hose 5, wherein the hose 5 is fixed to the output end of the submersible pump 4 by bolts.

[0039] When it is necessary to drain the dewatering well in the open-pit mine, the submersible pump 4, after being started, allows the well water to be discharged outside the well through the hose 5.

[0040] The top of the submersible pump 4 is fixed with a waterproof cable 2 3;

[0041] When it is necessary to drain the dewatering well of the open-pit mine, first install the end of the waterproof cable 23 away from the submersible pump 4 on the winch. The winch can control the winding and unwinding of the waterproof cable 23, so that the submersible pump 4 can be moved into the open-pit mine dewatering well under the traction of the waterproof cable 23. The waterproof cable 23 also serves as a power supply.

[0042] The airbag-type fixing component includes a cylinder 1, an electric telescopic rod 11, and a mounting frame 15. The mounting frame 15 is welded to the inner wall of the cylinder 1. The cylinder 1 and the shell 9 are fixedly connected. The electric telescopic rod 11 is fixed to the top outer wall of the mounting frame 15 by bolts. The output end of the electric telescopic rod 11 is fixed with a piston rod 12 by a pin. The bottom of the piston rod 12 is fixed with a piston plate 13. The outer circumference of the cylinder 1 is fixed with a connecting air pipe 16 by welding. The outer wall of the connecting air pipe 16 is fixed with an annular seat 7. An annular airbag 8 is installed on the inner wall of the annular seat 7. The annular airbag 8 and one end of the connecting air pipe 16 are connected by a connector. The end of the connecting air pipe 16 away from the annular airbag 8 is welded with a piston cylinder 14. The piston cylinder 14 and the piston plate 13 are slidably connected.

[0043] The annular airbag 8 is made of wear-resistant material. As the annular airbag 8 moves down along the open-pit mine dewatering well, it has a certain degree of flexibility before being inflated. When the cylinder 1 is affected by the water flow and shakes during the downward movement, the annular airbag 8 contacts the well wall to buffer and protect the cylinder 1. When the cylinder 1 moves to a certain depth, the piston rod 12 is driven down by the electric telescopic rod 11, causing the piston plate 13 to slide relative to the piston cylinder 14. The outer wall of the piston plate 13 is equipped with a rubber ring. The piston plate 13 compresses the gas pre-stored in the piston cylinder 14. After being compressed, the gas enters the annular airbag 8 through the air pipe piston cylinder 14. The annular airbag 8 expands continuously and fits against the well wall, supporting the cylinder 1 and ensuring the stability of the water pressure sensor 6 and the ultrasonic component 20 during monitoring. When the position of the monitoring component needs to be readjusted, the electric telescopic rod 11 drives the piston rod 12 to move in the opposite direction.

[0044] A waterproof cable 2 is fixed to the top outer wall of the cylinder 1;

[0045] Waterproof cable 12 and waterproof cable 23 move in the same way. Waterproof cable 12 can be used to transmit data to the monitoring components.

[0046] Working principle: The monitoring component and drainage component are lowered into the open-pit mine dewatering well in sequence. When the housing 9 moves the water pressure sensor 6 and ultrasonic component 20 to a specific depth in the well, the water level and the actual well depth are measured. The filter screen 10 filters the sand and gravel in the open-pit mine dewatering well to prevent sand and gravel from entering the device and protect the water pressure sensor 6 and ultrasonic component 20. When it is necessary to drain the open-pit mine dewatering well, the submersible pump 4 is started. After the submersible pump 4 is started, the well water passes through the submersible pump 4 and is finally discharged out of the well through the hose 5, realizing the drainage function of the open-pit mine dewatering well.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
