Description

Technical Field

[0001] This invention belongs to the field of monitoring well washing quality control technology, and more specifically, it relates to a monitoring well washing quality control device and a monitoring well washing apparatus. Background Technology

[0002] Hydrogeological investigation and groundwater contaminant detection are crucial steps in site environmental investigation. Both investigation and detection require the construction of monitoring wells. Over long-term use, these wells accumulate contaminants such as sediment, debris, and microbial communities. These contaminants can clog the filtration structure, affecting the accuracy of monitoring data and potentially damaging the monitoring equipment, thus shortening the well's lifespan. Therefore, regular cleaning of the monitoring wells is essential for ensuring their normal operation and reliable monitoring data. Inspecting the quality of the cleaning process afterward allows for timely assessment of whether the cleaning met standards, preventing incomplete cleaning from affecting monitoring work and providing a solid foundation for subsequent monitoring operations. Furthermore, according to the latest draft "Technical Specifications for Groundwater Environmental Monitoring" issued by the Ministry of Ecology and Environment, if a monitoring well is not frequently used and has been left unused for more than three months, it should be cleaned before sampling. Water samples must be collected from the well only after thorough cleaning.

[0003] In terms of well cleaning quality monitoring, there is a lack of effective on-site or remote real-time digital monitoring methods. Currently, the main approach relies on manual estimation of the well cleaning situation by eye. This method is highly subjective and greatly affected by factors such as human experience and observation angle, making it difficult to accurately reflect the true quality of the well cleaning. Alternatively, underwater television can be used to detect the cleaning process after the well is cleaned, but this cannot provide real-time monitoring during the cleaning process and is considered post-event inspection, which cannot allow for timely adjustments to the well cleaning process.

[0004] Chinese invention patent (patent application number: 201910621101.3) discloses a monitoring well washing device including a water pumping pipe; a blower for providing air power to the water pumping pipe; a water pumping device for pumping water from the monitoring well through the water pumping pipe; a metering device for measuring the amount of water pumped by the water pumping device; and a valve device, which is located at the outlet of the water pumping pipe and is used to adjust whether the outlet of the water pumping pipe is connected to the air supply pipe of the blower and disconnected from the water supply pipe of the water pumping device, or to adjust whether the outlet of the water pumping pipe is connected to the water supply pipe of the water pumping device and disconnected from the air supply pipe of the blower; the water pumping pipe, the blower, the water pumping device, and the metering device are all mounted on a support device.

[0005] While the aforementioned invention solves the problem of water accumulation and difficulty in pumping water by using a water pump and blower in combination, it also has the problem of not being able to monitor the well-washing process and quality in real time. This lack of real-time monitoring makes it difficult to guarantee the continuity and economy of well-washing operations. If a well-washing operation fails to meet standards, the current operation must be stopped and the process repeated, resulting in significant time wastage and reduced efficiency. Conversely, if a well-washing operation passes standards but continues due to a lack of timely awareness, it leads to unnecessary waste of manpower and water resources, increases costs, and makes it difficult to complete the well-washing operation continuously and economically to meet the standards in one go.

[0017] The beneficial effects of the well-washing quality monitoring device provided by this invention are as follows: Compared with the prior art, the device's advantages are significant.

[0040] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] It should be further noted that the accompanying drawings and embodiments of the present invention mainly describe the concept of the present invention. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0042] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0043] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" 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 the present invention 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 the present invention.

[0044] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0046] The present invention will now describe a monitoring device for well washing quality and a monitoring device for well washing.

[0047] like Figure 1 and Figure 8As shown, the first embodiment of the present invention provides a monitoring device for well washing quality, including a detection module 10 and a detection host 11; wherein, the detection module 10 includes a clamp 101, a detection box 102, an image sensor 103, a sealing door 104, and a viewing window 105; the detection box 102 is disposed on the outer circumferential surface of the clamp 101; the image sensor 103 is installed inside the detection box 102; the sealing door 104 is disposed on the detection box 102; the viewing window 105 is disposed at a position corresponding to the image sensor 103; the image sensor 103 is communicatively connected to the detection host 11.

[0048] First, the detection box 102 is securely fixed in a suitable position using clamps 101, ensuring that it will not shift due to water flow inside the well or external environmental factors. Next, the image sensor 103 is installed inside the detection box 102, with its lens facing the viewing window 105 on the sealing door 104, ensuring that the image sensor 103 can clearly capture images of the well's interior through the viewing window 105. The sealing door 104 is designed to be openable and closable, facilitating maintenance, adjustment, or replacement of the image sensor 103 when needed. During normal use, the sealing door 104 is closed to protect the image sensor 103.

[0049] The detection host 11, as the core of the entire device for control and data processing, offers flexible selection and configuration options. It can be a PLC-based control device or a specially developed one, and is equipped with a touchscreen display for convenient parameter setting and data viewing. For power supply, a high-capacity rechargeable 2V battery is preferred. This power supply method is not only portable and mobile, suitable for different monitoring sites, but also allows power to the image sensor 103 via an electrical interface, ensuring that the device can operate continuously for more than 8 hours after a full charge, meeting the needs of long-term monitoring. The electrical interfaces include at least a battery charging interface and an image sensor 103 interface, with each input interface matching the output signal format of the selected instruments, ensuring compatibility and stability between devices. The detection host 11 establishes a communication connection with the image sensor 103. The well images captured by the image sensor 103 can be wirelessly transmitted to the detection host 11 in real time. Operators can intuitively observe the situation inside the monitoring well through the touchscreen display, thereby judging the well cleaning quality.

[0050] Compared with existing technologies, in terms of ease of operation, the design of the clamp 101 simplifies the installation and disassembly of the detection module 10, the openable structure of the sealing door 104 facilitates maintenance of the image sensor 103, and the touch screen makes the operation of the detection host 11 more intuitive and easy to understand. Regarding data transmission and monitoring performance, the stable communication between the image sensor 103 and the detection host 11 enables real-time transmission of images from inside the well, allowing operators to promptly grasp the well-washing situation, quickly assess the well-washing quality, and improve the timeliness and accuracy of monitoring.

[0051] like Figure 2 As shown, the second embodiment of the present invention provides a monitoring well cleaning device, including a mobile trolley 12, a first connecting pipe 20, a second connecting pipe 30, a cleaning component 40, a gas delivery mechanism 50, a water suction mechanism 60, and a drive assembly 70; a support plate 13 is provided at the bottom of the front end of the mobile trolley 12; the first connecting pipe 20 is disposed on the support plate 13, and its two ends respectively penetrate the upper and lower surfaces of the support plate 13; the second connecting pipe 30 is rotatably disposed below the first connecting pipe 20, and its upper end is connected to the lower end of the first connecting pipe 20; the cleaning component 40 is sleeved on the outside of the second connecting pipe 30, and the outer surface of the second connecting pipe 30... A threaded section is provided along its length, the threaded section includes two sets of threads with opposite directions, and the two sets of threads are arranged crosswise. The cleaning component 40 is threadedly connected to the second connecting pipe 30. The air supply mechanism 50 is installed on the mobile trolley 12, and the air supply end is connected to the second connecting pipe 30. The water suction mechanism 60 is installed on the mobile trolley 12, and the water suction end is connected to the upper end of the first connecting pipe 20. The drive assembly 70 is installed on the support plate 13 and connected to the second connecting pipe 30, for driving the second connecting pipe 30 to rotate, and synchronously driving the cleaning component 40 to move up and down reciprocally along the length of the second connecting pipe 30.

[0052] Among them, the mobile trolley 12 serves as the supporting foundation of the entire device, and a support plate 13 is fixedly installed at the bottom of its front end. The design of the mobile trolley 12 makes the entire device easy to move and use, and can flexibly adapt to the operational needs of different monitoring wells.

[0053] The first connecting pipe 20 is vertically mounted on the support plate 13, with its two ends penetrating the upper and lower surfaces of the support plate 13 respectively, forming a vertically continuous channel structure. The second connecting pipe 30 is coaxially mounted below the first connecting pipe 20, and its upper end is sealed and connected to the lower end of the first connecting pipe 20 to ensure smooth fluid flow between the two pipes.

[0054] The cleaning component 40 is sleeved on the outside of the second connecting pipe 30 and fits against the outer surface of the second connecting pipe 30. A threaded section is machined along the length of the outer surface of the second connecting pipe 30. The threaded section includes two sets of threads with opposite directions, and the two sets of threads are arranged crosswise. The inner wall of the cleaning component 40 has a structure that matches the threaded section, so that the cleaning component 40 and the second connecting pipe 30 form a threaded connection.

[0055] The gas delivery mechanism 50 is installed at the rear end of the mobile trolley 12. Its gas delivery end is connected to the side wall of the second connecting pipe 30 through a gas delivery pipeline, and can continuously deliver high-pressure gas into the second connecting pipe 30. The water suction mechanism 60 is located in the middle area of ​​the mobile trolley 12. Its water suction end is connected to the upper end of the first connecting pipe 20 through a water suction pipeline, and is used to extract water from the monitoring well.

[0056] The drive assembly 70 is fixedly mounted on the upper surface of the support plate 13, and its output end is connected to the upper end of the second connecting pipe 30, enabling the second connecting pipe 30 to rotate. When the second connecting pipe 30 rotates, due to the fit between the cleaning component 40 and the threaded section, the cleaning component 40 will synchronously move up and down along the length of the second connecting pipe 30, thereby mechanically cleaning the well wall and the perforated pipe area of ​​the monitoring well.

[0057] Specifically, the air supply mechanism 50 is an air compressor or a blower, the water suction mechanism 60 is a water pump, and the mobile trolley 12 is also equipped with a power supply device 15. The air supply mechanism 50 and the water suction mechanism 60 are electrically connected to the power supply device 15 respectively.

[0058] The working process of this embodiment is as follows: The device is transported to the monitoring well by the mobile trolley 12, and the second connecting pipe 30 and the cleaning component 40 are lowered into the monitoring well; the air supply mechanism 50 and the water suction mechanism 60 are started. The air supply mechanism 50 provides wind power to blow up the mud and small particles of gravel at the bottom of the monitoring well, so that the water suction mechanism 60 can extract the water containing mud and sand through the first connecting pipe 20 and the second connecting pipe 30 to remove the mud and small particles of gravel; at the same time, the drive component 70 is started to drive the second connecting pipe 30 to run in both forward and reverse directions, which drives the cleaning component 40 to move up and down in the well to brush and clean the mud and attached debris on the well wall, especially at the perforated pipe position, to ensure that the perforated pipe holes are unobstructed.

[0059] Compared with existing technologies, when the drive component 70 drives the second connecting pipe 30 to rotate, the cleaning component 40 moves up and down along the pipe body 21, which can scrape the flower pipe position repeatedly. Combined with the airflow disturbance of the air supply mechanism 50, it significantly improves the unblocking effect of the flower pipe holes, ensures that the holes are open well, and solves the problem of insufficient flushing of the flower pipe by traditional devices.

[0060] The cleaning component 40 is in direct contact with the pipe wall. During its reciprocating motion, it physically removes mud and attached debris through a brushing action, replacing manual brushing operations. This improves cleaning efficiency while ensuring the stability of the cleaning effect and avoids debris residue interfering with subsequent monitoring.

[0061] By addressing the issues of insufficient flushing of perforated pipes and cleaning of pipe walls, the well environment after cleaning is made to better meet the requirements of the specifications, reducing the deviation of monitoring data caused by hole blockage or debris on the pipe wall, and providing a more reliable basis for groundwater monitoring.

[0062] like Figures 2 to 6 As shown, the second embodiment of the present invention provides a monitoring well washing device, wherein the second connecting pipe 30 includes a main pipe 31, a gravity pipe 32 and a branch pipe 33. The upper end of the main pipe 31 is rotatably connected to and communicates with the lower end of the rotary joint 71, the lower end of the main pipe 31 is rotatably connected to and communicates with the gravity pipe 32, one end of the branch pipe 33 is inclinedly disposed on one side of the gravity pipe 32 and communicates with the gravity pipe 32, and the other end of the branch pipe 33 is connected to the lower end of the gas guide pipe.

[0063] The second connecting pipe 30 adopts a split structure design, specifically including a main pipe 31, a gravity pipe 32, and a branch pipe 33 that are interconnected. The main pipe 31 is vertically arranged, and its upper end is rotatably connected to the lower end of the first connecting pipe 20 through a rotary joint 71. This ensures fluid communication between the main pipe 31 and the first connecting pipe 20 without affecting the forward and reverse rotation of the main pipe 31 with the drive assembly 70.

[0064] The lower end of the main pipe 31 is fixedly connected to a gravity pipe 32, and the upper end of the gravity pipe 32 is also connected to the lower end of the main pipe 31 via a rotary joint 71. This ensures fluid communication between the main pipe 31 and the gravity pipe 32 without affecting the forward and reverse rotation of the main pipe 31 with the drive assembly 70. The gravity pipe 32 is made of high-density metal material (such as cast iron or lead alloy) and has a large mass, which can prevent the wind reaction force generated when the gas delivery mechanism 50 is working from lifting the second connecting pipe 30 as a whole, ensuring that the cleaning component 40 can stably adhere to the well wall for cleaning operations.

[0065] Branch pipe 33 is installed at an angle to one side of gravity pipe 32, with an angle of 30°-45° between it and the axis of gravity pipe 32. One end of branch pipe 33 is connected to the interior of gravity pipe 32, and the other end is connected to air guide pipe. The upper end of air guide pipe is connected to the air delivery end of air delivery mechanism 50. When air delivery mechanism 50 is activated, high-pressure airflow enters the interior of gravity pipe 32 directly through air guide pipe and branch pipe 33, and then sprays out from the air outlet at the bottom of gravity pipe 32, precisely acting on the bottom of monitoring well, blowing up the deposited mud and small gravel, making it easier for water suction mechanism 60 to extract them through gravity pipe 32, main pipe 31, and first connecting pipe 20.

[0066] When the device is running, the high-pressure airflow generated by the gas delivery mechanism 50 enters the gravity pipe 32 through the branch pipe 33. While effectively blowing up the mud and sand at the bottom of the well, the gravity pipe 32, with its own large weight, offsets the reaction force generated by the airflow jet, ensuring that the second connecting pipe 30 always maintains a stable downward state. At the same time, when the drive component 70 drives the main pipe 31 to rotate, the cleaning component 40 simultaneously performs up-and-down reciprocating motion, which can form all-round airflow disturbance and mechanical cleaning on the well wall and the perforated pipe, further improving the well washing effect.

[0067] This invention designs the second connecting pipe 30 as a combination structure of a main pipe 31, a gravity pipe 32, and a branch pipe 33. This not only achieves efficient airflow delivery, but also solves the problem of pipe body 21 swaying and floating caused by airflow reaction force through the counterweight effect of the gravity pipe 32, thus ensuring the stability and reliability of cleaning operations.

[0068] like Figures 2 to 7 As shown, the second embodiment of the present invention provides a monitoring well washing device. A second support plate 14 is horizontally arranged above a first support plate 13. A ranging component 80 is arranged on the second support plate 14. The ranging component 80 includes a mounting frame 81, a support rod 82, a drum 83, and a wire rope 84. The mounting frame 81 is arranged on the second support plate 14. The support rod 82 is horizontally and rotatably arranged on the mounting frame 81. The drum 83 is sleeved in the middle of the support rod 82, and two baffles are respectively arranged at both ends of the drum 83. The wire rope 84 is wound on the drum 83, and a breaking cone 85 is arranged at the free end of the wire rope 84. The wire rope 84 and the breaking cone 85 are used to pass through the second support plate 14 and extend into the second connecting pipe 30.

[0069] Mounting bracket 81 is vertically fixed to the upper surface of support plate 14, providing stable support for the entire ranging assembly 80; support rod 82 is horizontally inserted between the two side walls of mounting bracket 81, and is rotatably connected to mounting bracket 81 through bearings, with one end extending to the outside of mounting bracket 81 and equipped with a crank handle; drum 83 is coaxially sleeved in the middle of support rod 82, fixedly connected to support rod 82, and rotates synchronously with support rod 82; both ends of drum 83 are equipped with circular baffles, the diameter of which is larger than the outer diameter of drum 83, to limit the winding range of wire rope 84 and prevent wire rope 84 from falling off; one end of wire rope 84 is fixed to drum 83, and the rest is neatly wound on the outer circumference of drum 83; a crushing cone 85 is fixedly connected to the free end of wire rope 84, the crushing cone 85 has a conical structure, with a sharp top and a bottom diameter slightly smaller than the inner diameter of the second connecting pipe 30. A through hole is provided at the corresponding position of the support plate 2 14, so that the wire rope 84 and the breaking cone 85 can pass through the through hole and extend into the monitoring well along the internal axial direction of the second connecting pipe 30.

[0070] Before starting well cleaning, the handle at the end of the support rod 82 is rotated to release the wire rope 84, allowing the breaking cone 85 to slowly sink along the second connecting pipe 30 under gravity. When the breaking cone 85 contacts the water surface, the lowering length is determined by sensing the tension change of the wire rope 84. Combined with the lowering depth of the second connecting pipe 30, the actual water level in the monitoring well can be calculated, providing basic data for subsequent well cleaning operations.

[0071] If a blockage is found in the second connecting pipe 30 during well cleaning (such as silt or sand accumulation causing obstructed water or air flow), the crushing cone 85 can be lowered using the crank handle. Its conical structure will impact the blockage, clearing the silt and sand from the second connecting pipe 30. If necessary, the crushing cone 85 can be moved up and down repeatedly to thoroughly remove the blockage through mechanical impact and restore the pipe's flow.

[0072] like Figures 2 to 7 As shown, the second embodiment of the present invention provides a monitoring well washing device. The drive assembly 70 includes a rotary joint 71, a first pulley 72, a rotating shaft 73, a second pulley 74, a first belt 75, a transmission assembly 79, and a drive component 76. The rotary joint 71 is located below the first connecting pipe 20, and its upper and lower ends are respectively connected to the first connecting pipe 20 and the second connecting pipe 30. The first pulley 72 is located on the first connecting pipe 20 below the rotary joint 71. The rotating shaft 73 is located on a support plate 13 on one side of the first connecting pipe 20, and its upper end penetrates the upper surface of the support plate 13. A driven bevel gear 78 is provided; a second pulley 74 is located at the lower end of the rotating shaft 73 that passes through the lower surface of the support plate; a first belt 75 is wound between the first pulley 72 and the second pulley 74; a driving member 76 is horizontally located on the upper surface of the support plate 13 on one side of the rotating shaft 73, and a driving bevel gear 77 is provided on its output shaft, which meshes with the driven bevel gear 78; an air guide pipe is vertically located on one side of the second connecting pipe 30, with its upper end connected to the air delivery end of the air supply mechanism 50, and its lower end passing through the lower surface of the cleaning member 40 and connected to the bottom side of the second connecting pipe 30. A transmission assembly 79 is used to drive the support rod 82 to rotate. The transmission assembly 79 includes a third pulley 791, a fourth pulley 792, and a second belt 793. The third pulley 791 is located on the output shaft between the driving bevel gear 77 and the driving member 76; the fourth pulley 792 is located at one end of the support rod 82; and the second belt 793 is wound between the third pulley 791 and the fourth pulley 792.

[0073] The drive assembly 70 serves as the power core of the device. Through multi-stage transmission, it can realize both the forward and reverse rotation of the second connecting pipe 30 and the rotation of the support rod 82. Specifically, it includes a rotary joint 71, a first pulley 72, a rotating shaft 73, a second pulley 74, a first belt 75, a third pulley 791, a fourth pulley 792, a second belt 793, and a drive component 76.

[0074] The rotary joint 71 adopts a mechanical seal structure. Its upper end is fixedly connected to the lower end of the first connecting pipe 20, and its lower end is rotatably connected to the upper end of the second connecting pipe 30. This ensures fluid communication between the first connecting pipe 20 and the second connecting pipe 30, and also provides mechanical support for the rotational movement of the second connecting pipe 30.

[0075] The first pulley 72 is fixedly sleeved on the upper outer wall of the second connecting pipe 30 and rotates synchronously with the second connecting pipe 30. A rotating shaft 73 is vertically arranged on the support plate 13 on one side of the first connecting pipe 20, which is rotatably mounted through a bearing seat: the lower end of the rotating shaft 73 extends to the bottom of the support plate 13 and is fixedly sleeved on the second pulley 74, and the upper end passes through the upper surface of the support plate 13 and is fixedly sleeved on the driven bevel gear 78. The first belt 75 is detachably wound between the first pulley 72 and the second pulley 74 to form the transmission path of the second connecting pipe 30.

[0076] The drive component 76 (a servo motor is used in this invention, but a hydraulic motor or pneumatic motor with rotation function can also be selected) is horizontally mounted on the upper surface of the support plate 13, located next to the rotating shaft 73. Its output end is fixedly fitted with an active bevel gear 77, which meshes with the driven bevel gear 78, and can convert the horizontal rotational power into the vertical rotational power of the rotating shaft 73.

[0077] The air guide tube is vertically installed on one side of the second connecting tube 30, and its upper and lower ends pass through the upper and lower surfaces of the cleaning component 40, respectively. Since the inner surface of the cleaning component 40 is threadedly connected to the outer surface of the second connecting tube 30, and in conjunction with the use of the air guide tube, the cleaning component 40 can move up and down along the length of the second connecting tube 30.

[0078] The third pulley 791 is fixedly sleeved on the output shaft of the drive component 76. One end of the support rod 82 in the ranging assembly 80 (away from the crank handle) is fixedly sleeved with the fourth pulley 792. The second belt 793 is also detachable and is wound between the third pulley 791 and the fourth pulley 792 to form the transmission path of the support rod 82.

[0079] During well wall cleaning operations: The first belt 75 is installed (the second belt 793 is disconnected). Power from the drive component 76 is transmitted via the driving bevel gear 77 → driven bevel gear 78 → rotating shaft 73 → second pulley 74 → first belt 75 → first pulley 72 to the second connecting pipe 30, driving it to rotate. This causes the cleaning component 40 to reciprocate up and down, thus cleaning the well wall and perforated pipe. At this time, the support rod 82 does not rotate with the drive component 76, and the breaking cone 85 remains stationary.

[0080] During pipeline dredging operations: The first belt 75 is disassembled (and the second belt 793 is installed). Power from the drive unit 76 is transmitted to the support rod 82 via the third pulley 791 → second belt 793 → fourth pulley 792, causing the drum 83 to rotate and the wire rope 84 to be wound and unwound. This allows the crushing cone 85 to move up and down within the second connecting pipe 30, impacting and clearing silt and sand from the pipe. At this time, the second connecting pipe 30 does not rotate with the drive unit 76 to prevent the cleaning unit 40 from interfering with the dredging operation.

[0081] When measuring the water level before well cleaning: all belts can be disconnected, and the crushing cone 85 can be lowered by manually rotating the crank handle of the support rod 82. The lowering speed can be precisely controlled to measure the water level height, avoiding the influence of power transmission on the measurement accuracy.

[0082] This embodiment utilizes a detachable belt to selectively switch the transmission path, allowing the drive unit 76 to independently drive the second connecting pipe 30 or the support rod 82 according to operational needs. This ensures the independence of well wall cleaning and pipe dredging operations while simplifying the power system structure and reducing equipment costs. Simultaneously, the servo motor's forward / reverse control and speed adjustment functions can adapt to cleaning well wall deposits of varying hardness and dredging pipes with different degrees of blockage, enhancing the device's adaptability.

[0083] like Figure 2 and Figure 3 As shown, the first embodiment of the present invention provides a monitoring well washing device. The first connecting pipe 20 includes a pipe body 21 and two connecting discs 22 disposed at both ends thereon. The support plate 13 has an opening in the middle, and the pipe body 21 is embedded in the opening. Each connecting disc 22 has multiple through holes along its circumference. Each through hole is provided with a fastener. The fastener passes through the connecting disc 22 above the pipe body 21, the support plate 13, and the connecting disc 22 below the pipe body 21 in sequence, and is used to fix the first connecting pipe 20 on the support plate 13.

[0084] The first connecting pipe 20 includes a pipe body 21 and two connecting discs 22. The pipe body 21 is a cylindrical hollow pipe with both ends open. Its material can be high-strength PVC or metal to ensure structural strength and corrosion resistance. The two connecting discs 22 are fixedly installed at the upper and lower ends of the pipe body 21, respectively. The connecting discs 22 are circular with a diameter larger than the outer diameter of the pipe body 21 and are arranged coaxially with the pipe body 21. The connecting discs 22 and the pipe body 21 can be sealed and fixed by welding (for metal materials) or integral injection molding (for PVC materials).

[0085] The support plate 13 has an opening in the middle that matches the tube body 21 of the first connecting pipe 20. The diameter of the opening is slightly larger than the outer diameter of the tube body 21 and smaller than the diameter of the connecting disc 22. During assembly, the tube body 21 is vertically embedded in the opening, so that the connecting disc 22 located above is attached to the upper surface of the support plate 13, and the connecting disc 22 located below is attached to the lower surface of the support plate 13, forming an upper and lower clamping structure for the support plate 13.

[0086] Each connecting disc 22 has 4-6 through holes evenly spaced along its circumference. The positions of the through holes on the upper and lower connecting discs 22 correspond one-to-one and are aligned with the preset mounting holes on the support plate 13. During assembly, a fastener (a bolt and nut assembly can be used) is inserted into each through hole. The fastener passes through the connecting disc 22 located above the tube body 21, the support plate 13, and the connecting disc 22 located below the tube body 21 in sequence. By tightening the nuts, the two connecting discs 22 tightly clamp the support plate 13, thereby firmly fixing the first connecting pipe 20 to the support plate 13.

[0087] The double connecting disc 22 clamping design ensures the connection stability between the first connecting pipe 20 and the support plate 13, preventing loosening caused by the vibration of the pipe body 21 during well washing; multiple evenly distributed fasteners can distribute the force and prevent the support plate 13 from being damaged due to excessive local stress; the detachable bolt connection method facilitates the installation, disassembly, maintenance and replacement of the first connecting pipe 20.

[0088] like Figures 5 to 9 As shown, the second embodiment of the present invention provides a monitoring well cleaning device. The cleaning component 40 includes a cleaning inner ring 41, a cleaning outer ring 44, scrapers 42, cleaning brushes 43, and a swing mechanism 45. The inner surface of the cleaning inner ring 41 is provided with an array of protruding structures, which are threadedly connected to the threaded section on the second connecting pipe 30. The outer surface of the cleaning inner ring 41 is provided with multiple mounting grooves along its circumference. Each mounting groove is provided with a swing mechanism 45. The output end of the swing mechanism 45 is connected to the inner surface of the cleaning outer ring 44 and is used to drive the cleaning outer ring 44 to swing back and forth around the cleaning inner ring 41. The outer surface of the cleaning outer ring 44 is provided with multiple scrapers 42 along its circumference, and a cleaning brush 43 is provided between any two scrapers 42. The swing mechanism 45 includes a piezoelectric motor 451 and a connecting ear plate 452. There are multiple piezoelectric motors 451, and each one corresponds to a mounting slot. The output end of the piezoelectric motor 451 is provided with a connecting ear plate 452, which is connected to the inner surface of the cleaning outer ring 44.

[0089] The inner cleaning ring 41 is a cylindrical structure with an array of raised structures on its inner surface. These raised structures match the threaded sections on the second connecting pipe 30 and are threadedly fitted onto the outside of the second connecting pipe 30. Multiple mounting slots are evenly distributed along the circumferential direction of the outer surface of the inner cleaning ring 41, and each mounting slot houses a swing mechanism 45.

[0090] The oscillating mechanism 45 includes a piezoelectric motor 451 and a connecting ear plate 452. The number of piezoelectric motors 451 corresponds one-to-one with the mounting slots. The piezoelectric motors 451 are fixedly installed in the mounting slots, and their output ends are connected to the connecting ear plates 452. The connecting ear plates 452 are fixedly connected to the inner surface of the cleaning outer ring 44. When the piezoelectric motors 451 are working, they drive the cleaning outer ring 44 to oscillate back and forth around the cleaning inner ring 41 through the connecting ear plates 452, thereby enhancing the cleaning effect.

[0091] Multiple scrapers 42 are arranged along the circumference of the outer surface of the cleaning outer ring 44. The scrapers 42 are made of wear-resistant material and can effectively scrape away thicker sludge and impurities on the well wall. A cleaning brush 43 is arranged between any two scrapers 42. The cleaning brush 43 is made of high-strength bristles, such as a mixture of nylon or steel wire, and the bristles are slightly longer than the outer edge of the scraper 42, allowing it to reach deep into the orifices of the perforated pipe for cleaning. The cleaning outer ring 44 is driven to swing back and forth by the swing mechanism 45, so that the scrapers 42 and the cleaning brush 43 can make more comprehensive contact with the well wall. The combined effect of the two forms a highly efficient cleaning mode, which greatly improves the cleaning efficiency and effect of the well washing device.

[0092] Compared with existing technologies, scraper 42 is mainly used to scrape off larger pieces of mud and hard debris adhering to the well wall and perforated pipe surface, and removes stubborn deposits through mechanical scraping. Cleaning brush 43 further cleans up the remaining fine mud and sand after scraper 42 cleaning, and thoroughly brushes the perforated pipe holes to ensure that the holes are unobstructed. The two work together to form a "scraper-brush" combined cleaning mode, which, together with the airflow disturbance of gas delivery mechanism 50, can comprehensively remove well wall deposits of different types and hardness.

[0093] like Figure 6 As shown, the clamp 101 is fitted onto the upper end of the cleaning inner ring 41, and an opening is provided on one side of the clamp 101. This opening can be locked by fasteners. When the cleaning inner ring 41 moves up and down, the clamp 101 can drive the detection module 10 to move up and down, thereby monitoring the cleaning status in the monitoring well in real time.
