Description

Technical Field

[0001] This utility model relates to the technical field of well monitoring devices, and in particular to a well water depth and well sand monitoring device. Background Technology

[0002] In open-pit mines located in areas with abundant shallow water resources, the stability of slopes and the safety of topsoil stripping and mining operations are directly related to the mine's production efficiency and the safety of personnel and property. As a key preliminary process to ensure the safety of the above operations, the importance of dewatering operations is self-evident. The boundaries of open-pit mines can often reach tens of square kilometers. Such a vast distribution area poses a huge challenge to the manual management of dewatering wells.

[0003] Open-pit mines can reach depths of hundreds of meters, and the corresponding actual depths of drainage wells are even greater. Submersible pumps in open-pit mine drainage wells are constantly in operation and are prone to running dry. When a submersible pump is running dry, it is not performing normal drainage operations, but the motor is still running, which also generates heat. Due to the lack of water flow for cooling, heat dissipation is also poor, eventually leading to the burnout of the submersible pump. Therefore, achieving high-precision, real-time monitoring of water levels and silt accumulation in drainage wells is of great significance in preventing submersible pumps from running dry due to lack of water flow for cooling, which can lead to poor heat dissipation and ultimately burnout.

[0004] Based on the numerous serious problems existing in the dewatering operations of open-pit mines, a monitoring device for water depth and sand in wells is designed to facilitate high-precision, real-time monitoring of water level and silt accumulation in dewatering wells. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for monitoring water depth and sand in wells.

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

[0007] A well water depth and well sand monitoring device includes a housing, a support assembly installed inside the housing, a submersible pump fixed at the bottom of the housing, a second housing mounted on the submersible pump, a mounting base fixed to the inner wall of the second housing, a monitoring module mounted on the mounting base, and a water pressure sensor and an ultrasonic ranging assembly respectively mounted at the bottom of the mounting base.

[0008] As a further embodiment of this utility model: the monitoring module includes a water level monitoring module, a power supply module, an edge computing and communication module, and a well depth monitoring module, and the water level monitoring module, the power supply module, the edge computing and communication module, and the well depth monitoring module are electrically connected to each other.

[0009] As a further embodiment of this utility model: the support assembly includes an electric telescopic rod and a fixed base. The fixed base is fixed to an inner wall of the housing, and the electric telescopic rod is fixed to the top outer wall of the fixed base. The output end of the electric telescopic rod is fixed to a lifting seat by a pin.

[0010] As a further embodiment of this utility model: a sliding rod is movably connected to one side wall of the housing, and a support plate is welded to one end of the sliding rod, and a bracket is fixed to the other end of the sliding rod, and a swing arm is movably connected between the inner wall of the bracket and the inner wall of the lifting seat.

[0011] As a further improvement of this utility model, the output end of the submersible pump is fixed with a flexible hose by bolts.

[0012] As a further improvement of this utility model, a filter screen is fixed to the bottom of the second housing by screws.

[0013] As a further improvement of this utility model, a waterproof sleeve is installed on the top of the housing.

[0014] As a further improvement of this utility model, a wire is installed inside the waterproof sleeve.

[0015] Compared with the prior art, this utility model provides a device for monitoring well water depth and well sand, which has the following beneficial effects:

[0016] 1. Through a water pressure sensor and an ultrasonic ranging component, the device can simultaneously achieve real-time and accurate measurement of water level and actual well depth. The water pressure sensor utilizes the linear relationship between hydrostatic pressure and water depth, while the ultrasonic ranging component accurately obtains the distance to the top surface of the sand accumulation at the bottom of the well by measuring the time difference between transmitting and receiving sound waves, thereby calculating the actual well depth and ensuring the comprehensiveness and accuracy of the data. The edge computing and communication module in the monitoring module can receive and process data from the water level monitoring module and the well depth monitoring module in real time. It acquires the water pressure P and time difference t at a preset frequency, calculates the water level and actual well depth, and quickly transmits the results to the host computer. This intelligent data processing and communication mechanism greatly improves monitoring efficiency.

[0017] 2. The support assembly drives the lifting seat to move downward via an electric telescopic rod. The vertical movement of the lifting seat is converted into the lateral movement of the sliding rod by the swing arm, so that the support plate fits tightly against the well wall, providing stable support for the device. It can adapt to dewatering wells of different diameters and ensure the stability of the device during the monitoring process.

[0018] 3. A submersible pump is installed at the bottom of the device. By controlling the start of the submersible pump, well water can be extracted. The well water enters the submersible pump and is then discharged from the wellhead through a hose. This water pumping method is simple to operate, highly efficient, and can meet the water pumping needs in different scenarios. At the same time, it achieves natural cooling of the motor. This self-cooling mechanism eliminates the need for additional cooling equipment, reducing energy consumption and costs, ensuring the stability and reliability of the motor during long-term operation, and effectively avoiding motor damage caused by overheating.

[0019] 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 well water depth and well sand monitoring device, in order to improve monitoring efficiency, such as... Figures 1 to 4 As shown, the system includes a housing 1, inside which a support assembly is installed. A waterproof sleeve 2 is installed on the top of the housing 1. A submersible pump 6 is fixed to the bottom of the housing 1 by bolts, and a hose 3 is fixed to the output end of the submersible pump 6 by bolts. A housing 4 is installed on the submersible pump 6. A mounting base 10 is fixed to the inner wall of the housing 4, and a monitoring module is installed on the mounting base 10. The monitoring module includes a water level monitoring module 15, a power module 16, an edge computing and communication module 17, and a well depth monitoring module 18. The water level monitoring module 15, the power module 16, the edge computing and communication module 17, and the well depth monitoring module 18 are electrically connected. A water pressure sensor 19 and an ultrasonic ranging assembly 5 are respectively installed at the bottom of the mounting base 10. A filter screen 20 is fixed to the bottom of the housing 4 by screws.

[0028] When monitoring of the dewatering well is required, the entire device can be suspended and extended into the dewatering well using the waterproof sleeve 2. Specifically, the end of the waterproof sleeve 2 away from the shell 1 is installed on the unwinding and winding equipment. During the unwinding and winding process of the waterproof sleeve 2, the entire device moves down along the dewatering well. At the same time, the waterproof sleeve 2 is equipped with wires, which can be used for signal transmission and power supply. When the entire device moves to a suitable depth, the support components support the well wall to ensure the stability of the entire device during monitoring.

[0029] The water pressure sensor 19 can be used for monitoring operations. When it is necessary to measure the water level using the water pressure sensor 19, the net water pressure P is measured by the water pressure sensor 19, 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 ranging component 5 to measure the actual well depth (the distance from the wellhead to the top surface of the sand accumulation at the bottom of the well), the time difference t between the ultrasonic ranging component 5 transmitting and receiving is used to calculate the distance from the ultrasonic ranging component 5 to the top surface of the sand accumulation 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] The water level monitoring module 15 is connected to the water pressure sensor 19 and transmits the monitored water pressure to the edge computing and communication module 17. The power module 16 provides power. The edge computing and communication module 17 obtains basic data such as monitoring frequency and sensor installation location from the host computer. It obtains water pressure P and time difference t used to calculate water level and actual well depth from the water level monitoring module 15 and well depth monitoring module 18 at a certain frequency, calculates water level and actual well depth, and communicates the calculation results with the host computer. The well depth monitoring module 18 monitors the ultrasonic transmission-reception time difference t and transmits the monitored time difference t to the edge computing and communication module 17 to realize real-time measurement of water level and actual well depth. The depth of the submersible pump 6 is adjusted according to the water level to avoid the height of the submersible pump 6 being higher than the water level, which would cause the submersible pump 6 to run idle without normal drainage operation, and the motor would still run and generate heat. Due to the lack of water flow for cooling, heat dissipation would be poor, eventually causing the submersible pump 6 to burn out.

[0037] When well water needs to be extracted, the submersible pump 6 is started by controlling it. Well water enters the submersible pump 6 and the hose 3. The well water can be discharged from the wellhead using the hose 3. At the same time, the well water is used to cool the motor inside the submersible pump 6.

[0038] The support assembly includes an electric telescopic rod 9 and a fixed seat 14. The fixed seat 14 is fixed to the inner wall of the housing 1 by bolts, and the electric telescopic rod 9 is fixed to the top outer wall of the fixed seat 14 by bolts. The output end of the electric telescopic rod 9 is fixed to a lifting seat 12 by a pin. A sliding rod 8 is slidably connected to the side wall of the housing 1. A support plate 7 is welded to one end of the sliding rod 8, and a bracket 11 is fixed to the other end of the sliding rod 8 by bolts. A swing arm 13 is rotatably connected between the inner wall of the bracket 11 and the inner wall of the lifting seat 12.

[0039] When the support assembly needs to be supported at the well wall, the electric telescopic rod 9 drives the lifting seat 12 to move down, and the swing arm 13 converts the vertical movement of the lifting seat 12 into the lateral movement of the slide rod 8 along the shell 1. When the slide rod 8 drives the support plate 7 to move to fit against the well wall, the support operation is completed. In actual operation, a sealing ring can be installed at the connection between the slide rod 8 and the shell 1 to ensure that well water does not enter the interior of the shell 1 during the sliding of the slide rod 8 along the shell 1.

[0040] Working principle: The waterproof sleeve 2 is unwound using a winding and unwinding device, allowing the entire device to move down along the dewatering well. Once the device reaches the appropriate depth, the electric telescopic rod 9 is activated, driving the lifting seat 12 to move downwards. The swing arm 13 converts the vertical movement of the lifting seat 12 into the lateral movement of the sliding rod 8 along the shell 1. The sliding rod 8 drives the support plate 7 to move until it is in contact with the well wall, completing the support operation and ensuring the stability of the entire device during monitoring. The water pressure sensor 19 and the ultrasonic ranging component 5 are used to monitor the water level and actual well depth. The water level monitoring module 15 is connected to the water pressure sensor 19, transmitting the monitored water pressure to the edge computing and communication module 17. The power module 16 is used for the water level monitoring module 15 and the edge computing and communication module. The edge computing and communication module 17 and the well depth monitoring module 18 are powered. The edge computing and communication module 17 obtains basic data such as monitoring frequency and sensor installation location from the host computer. It obtains water pressure P and time difference t used to calculate water level and actual well depth from the water level monitoring module 15 and the well depth monitoring module 18 at a certain frequency, and performs calculations on water level and actual well depth. The calculation results are communicated with the host computer. The well depth monitoring module 18 monitors the ultrasonic transmission-reception time difference t and transmits the monitored time difference t to the edge computing and communication module 17 to realize real-time measurement of water level and actual well depth. When well water needs to be pumped, the submersible pump 6 is controlled to start. Well water enters the submersible pump 6 and the hose 3, and the well water is discharged from the wellhead using the hose 3.

[0041] 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.
