Description

Technical Field

[0001] The present invention belongs to the technical field of monitoring devices, and more specifically, particularly relates to a water environment monitoring device for coal mining subsidence areas. Background Art

[0002] With the continuous mining of coal, large areas of land are prone to change their original landforms due to collapse. At the same time, waste slag, wastewater, etc. generated in the coal mining process may also pollute the water environment, leading to the deterioration of water quality in the area, thereby affecting the water use of surrounding residents. In order to timely grasp the changes in water quality in the water environment of the coal mining subsidence area and take effective response measures, it is necessary to use water environment monitoring equipment that can monitor the water environment parameters of the coal mining subsidence area in real time, and provide powerful data for protecting the ecological environment and ensuring the safety of residents' living water.

[0003] In coal mining subsidence areas, due to the continuous impact of coal mining activities and the influence of natural factors, water quality will show non-directional changes over time; in order to further analyze the changing trend of water quality, determine potential sources of pollution and evaluate the effectiveness of control measures, it is often necessary to sample water sources in coal mining subsidence areas and conduct more detailed detection of water sources through different detection methods; however, traditional water environment monitoring devices can only perform a single monitoring function on water sources, so that when a more in-depth analysis of water sources is required during the monitoring process, it is impossible to perform effective sampling operations on water sources in coal mining subsidence areas. In addition, additional manual sampling operations are required, and manual sampling is inefficient. At the same time, it may be interfered by various external factors, resulting in reduced sample accuracy and reliability. Summary of the invention

The detection probe 22 and the detector body 21 are electrically connected, and the two work together to measure various key indicators in the water source. For example, important parameters such as pH, dissolved oxygen content, and heavy metal concentration in water can be accurately detected. The detection probe 22 can adopt a HACH LDO dissolved oxygen probe. A sampling assembly and a second water pump 33 are also provided above the workbench 11. The second water pump 33 is connected to the detection box 31 and the sampling assembly through a connecting pipe, respectively. The sampling assembly can realize automatic sampling of the water source during the monitoring process, thereby improving work efficiency. At the same time, a cleaning assembly is also provided above the workbench 11, which can regularly clean the detection probe 22 to provide a guarantee for the continuous and stable operation of the device. A partition 13 is provided on the workbench 11, and a first protective cover 34 and a second protective cover 35 are provided on both sides of the partition 13, respectively, and both are firmly connected to the workbench 11, thereby forming a first protective cavity and a second protective cavity. The sampling assembly is placed in the first protective cavity, while the moving assembly and the cleaning assembly are both located in the second protective cavity. A battery box is also provided in the second protective cavity, and a storage battery is provided in this battery box. The energy storage battery provides the required electrical energy for the entire monitoring device, ensuring that the device can operate stably in various environments. At the same time, a solar panel is arranged on the second protective cover 35. The solar panel can convert solar energy into electrical energy to charge the energy storage battery, further improving the energy self-sufficiency of the device.

[0037] like Figure 2 , Figure 5 , Figure 7As shown, the mobile assembly includes two groups of slide rails 41 and two groups of support frames 42. Two groups of support platforms 14 are arranged above the workbench 11. The slide rails 41 are connected to the support platforms 14 by bolts to ensure the stability of the slide rails 41. The detection box 31 is placed between the two groups of support platforms 14. An electric slider 43 is slidably arranged on the slide rail 41. The electric slider 43 can move smoothly on the slide rail 41, providing a basic moving function for the entire mobile assembly. The support frame 42 is located above the electric slider 43 and is detachably connected to the electric slider 43 by screws, so that the installation and disassembly of the support frame 42 becomes very convenient, and it is convenient for maintenance and replacement when necessary. At the same time, the screw connection also ensures that the connection between the support frame 42 and the electric slider 43 is firm and reliable, and will not loosen or fall off during the movement. A connecting frame 44 is provided between the two groups of support frames 42 . A connecting slot 45 is provided on the connecting frame 44 . The detection probe 22 is inserted into the connecting slot 45 , so that the detection probe 22 can move with the movement of the connecting frame 44 , thereby realizing the back and forth movement between the cleaning assembly and the detection box 31 .

[0038] The moving assembly also includes two groups of rotating gears 46. A slot is provided on the support frame 42. The rotating gear 46 is clamped in the slot and rotatably connected to the support frame 42, which not only ensures the stability of the rotating gear 46, but also enables the rotating gear 46 to rotate freely. Two groups of connecting frames 47 are provided on the connecting frame 44. Racks 48 are provided on both sides of the connecting frame 44. The racks 48 are clamped in the connecting frames 47. The rotating gear 46 and the rack 48 are meshed with each other. When the rotating gear 46 rotates, the connecting frame 44 can be driven to move up and down through the meshing action with the rack 48. The connecting frame 44 drives the detection probe 22 to move up and down, and the detection probe 22 can be freely entered and exited from the detection box 31; when the detection probe 22 needs to be cleaned, the detection probe 22 rises and exits the detection box 31 through the cooperation of the rotating gear 46 and the rack 48, and then moves to the top of the cleaning assembly through the electric slider 43, and descends into the cleaning assembly to complete the cleaning of the detection probe 22. A first motor 49 is installed on one side of the support frame 42, and the shaft end of the first motor 49 is connected to the rotating gear 46. The first motor 49 provides power for the rotation of the rotating gear 46. By controlling the speed and direction of the first motor 49, the speed of the up and down movement of the connecting frame 44 can be controlled. The connecting frame 44 is located above the detection box 31. The detection box 31 is provided with a first through slot 36, and one end of the connecting frame 44 is clamped in the first through slot 36. This makes the connecting frame 44 more stable during movement, and there will be no shaking or deviation. At the same time, the first through slot 36 also provides a certain guiding effect for the movement of the connecting frame 44, ensuring that the connecting frame 44 can be accurately moved to the required position.

[0039] like Figures 1 to 3 , Figure 6 As shown, the sampling assembly includes a lifting bracket 501 and an injection head 502. A fixed frame 503 is arranged on the partition 13. Both ends of the fixed frame 503 are installed with first bearings. At the same time, a first screw rod 504 is arranged on one side of the partition 13. Both ends of the first screw rod 504 are inserted into the first bearing so that the first screw rod 504 can rotate smoothly. One end of the lifting bracket 501 is clamped in the fixed frame 503 and sleeved on the first screw rod 504, so that the lifting bracket 501 can be slidably connected with the first screw rod 504. The injection head 502 is clamped on the lifting bracket 501 and connected to the second water pump 33. A lifting motor 505 is arranged at the bottom of the fixed frame 503, and the shaft end of the lifting motor 505 is connected to the first screw rod 504. When sampling is required, the lifting motor 505 is started to drive the first screw rod 504 to rotate, so that the lifting bracket 501 moves up and down along the first screw rod 504 to adjust the height position of the injection head 502 so that the sampling bottle can be accurately aligned to inject the sampling water source.

[0040] The sampling assembly also includes a rotating disk 506. A protrusion 15 is provided on the workbench 11. A connecting slot 16 is provided on the protrusion 15. The second bearing is clamped in the connecting slot 16. The bottom of the rotating disk 506 is clamped in the second bearing, so that the rotating disk 506 is rotatably connected to the protrusion 15. A rotating motor 507 is provided on the workbench 11. The rotating motor 507 is connected to the rotating disk 506 through a transmission belt 508. When multiple sampling samples are required, the rotating motor 507 is started, and the rotating disk 506 is driven to rotate through the transmission belt 508, and the sampling bottle is accurately rotated to the bottom of the injection head 502. The lifting motor 505 is rotated to move the lifting bracket 501 downward, and the injection tube at the bottom of the injection head 502 is inserted into the sampling bottle. A placement slot is provided on the first protective cover 34, and the first protective cavity is connected to the outside world through the placement slot. A protective cover plate 37 is provided on one side of the first protective cover 34, and the protective cover plate 37 is connected to the first protective cover 34 by rotation. The rotating disk 506 is clamped in the placement slot and is located between the first protective cover 34 and the protective cover plate 37. This not only ensures that the rotating disk 506 can rotate normally, but also provides a certain degree of protection for it, reduces the interference of external factors on the sampling process, and is also convenient for placing and taking the sampling bottle.

[0041] like Figure 3 , Fig. 9As shown, the rotating disk 506 is provided with multiple groups of placement grooves 509, and the sampling bottle can be stuck in the placement grooves 509. The sampling bottle includes a bottle body 510, and the bottle body 510 is stuck in the placement groove 509 to ensure that it will not shake or fall during the rotation process. A bottle cap 511 is arranged above the bottle body 510, and the bottle cap 511 is detachably connected to the bottle body 510, which is convenient for processing and analyzing the water sample in the bottle after sampling. A liquid inlet hole 512 is arranged on the bottle cap 511, and a sealing cover plate 513 is arranged between the bottle cap 511 and the bottle body 510, and the sealing cover plate 513 is rotatably connected to the bottle cap 511. When sampling is not performed, the top of the sealing cover plate 513 is stuck in the liquid inlet hole 512 to effectively prevent external impurities from entering the bottle. A flip cover spring is also arranged between the sealing cover plate 513 and the bottle cap 511. When sampling is performed, the injection head 502 descends, exerting pressure on the sealing cover plate 513 to open the liquid inlet 512, and the water sample flows smoothly into the bottle. After sampling is completed, the injection head 502 withdraws from the sampling bottle, and the sealing cover plate 513 automatically closes the liquid inlet 512 under the restoring force of the flip spring, further ensuring the quality of the sample. In addition, a protective frame 514 is provided at the bottom of the injection head 502, and the injection tube at the bottom of the injection head 502 is located in the protective frame 514. The protective frame 514 can protect the injection tube at the bottom of the injection head 502. During the descent of the injection head 502, the protective frame 514 will contact the sealing cover plate 513 in the first place to prevent the injection tube of the injection head 502 from contacting the sealing cover plate 513, thereby preventing the injection tube from being damaged by accidental collision during the sampling process.

[0042] like Figure 2 , Figure 3 , Figure 8 As shown, the cleaning assembly includes a cleaning box 601 and a liquid storage tank 602. The cleaning box 601 is located in the second protective cavity and connected to the workbench 11. The cleaning cover 603 is connected to the cleaning box 601, thereby forming a cleaning cavity. The cleaning cavity provides a relatively closed space for cleaning the detection probe 22, reducing the interference of external factors on the cleaning process. The liquid storage tank 602 is located in the first protective cavity. A special cleaning liquid is placed in the liquid storage tank 602. The cleaning liquid can effectively remove various impurities and contaminants on the detection probe 22. A liquid inlet 604 is provided on the top of the liquid storage tank 602, which is convenient for timely addition of cleaning liquid when it is insufficient. When it is necessary to replenish the cleaning liquid in the liquid storage tank 602, the first protective cover 34 needs to be disassembled and then filled through the liquid inlet 604. Two groups of nozzles 605 are arranged in the cleaning box 601. The two groups of nozzles 605 are symmetrically distributed so that the cleaning liquid can be evenly sprayed on the detection probe 22. The liquid storage tank 602 is connected to the two groups of nozzles 605 respectively through the third water pump 606. The third water pump 606 can pressurize the cleaning liquid in the liquid storage tank 602 and transport it to the nozzle 605, ensuring that the cleaning liquid is sprayed with sufficient pressure to preliminarily rinse the detection probe 22 and remove most of the impurities on the surface.

[0043] The cleaning assembly also includes two groups of telescopic electric cylinders 609. Two groups of assembly slots 610 are provided in the cleaning box 601. The telescopic electric cylinders 609 are clamped in the assembly slots 610 and are relatively distributed, so that the installation of the telescopic electric cylinders 609 is more stable and will not shake or deviate during operation. An assembly frame 611 is provided at one end of the telescopic electric cylinder 609, and a drive motor 612 is provided in the assembly frame 611. Two groups of cleaning brushes 613 are provided in the cleaning chamber, and the shaft end of the drive motor 612 is connected to the cleaning brush 613. When the detection probe 22 needs to be deeply cleaned, the telescopic electric cylinder 609 extends out, driving the assembly frame 611 and the drive motor 612 to approach the detection probe 22, and the drive motor 612 starts, driving the cleaning brush 613 to rotate, cleaning the detection probe 22 and removing stubborn stains. A second through slot 614 is provided on the cleaning cover 603. During the cleaning process, the detection probe 22 is moved out of the detection box 31 by the moving assembly through the moving assembly, and then moved into the cleaning box 601. During this process, the connecting frame 44 on the moving assembly will be stuck in the second through slot 614, which can effectively ensure the sealing of the cleaning box 601 and prevent the cleaning liquid from leaking during the cleaning process. When the detection probe 22 smoothly enters the cleaning box 601, it will be located between the two groups of cleaning brushes 613. Subsequently, driven by the telescopic electric cylinder 609, the cleaning brush 613 slowly approaches the detection probe 22 until it contacts the detection probe 22. It ensures that the cleaning brush 613 can perform a comprehensive and detailed cleaning of the detection probe 22 to remove various impurities and contaminants on its surface. At the same time, the sealing also makes the cleaning process more efficient and safe, providing a strong guarantee for the cleaning of the detection probe 22 and the stable operation of the monitoring device.

[0044] like Figure 2 , Fig.11 , Fig.12 As shown, a first drain pipe 615 is provided at the bottom of the cleaning box 601, and a second drain pipe 39 is provided at the bottom of the detection box 31. Solenoid valves are provided at one end of the first drain pipe 615 and the second drain pipe 39. A waste liquid tank 616 and a waste liquid pipe 17 are provided at the bottom of the workbench 11. The first drain pipe 615 is connected to the waste liquid tank 616 through a solenoid valve, and the waste liquid after cleaning can flow into the waste liquid tank 616 through the first drain pipe 615 for centralized treatment. The second drain pipe 39 is connected to the waste liquid pipe 17 through a solenoid valve, and the waste liquid in the detection box 31 can also be discharged in time, making the treatment of the waste liquid more convenient and environmentally friendly, and avoiding the waste liquid from causing secondary pollution to the detection probe 22 and the equipment.

[0045] like Figure 2 , Fig.10As shown, in the coal mining subsidence area water environment monitoring device, a fixed bracket 18 is provided at one end of the workbench 11, and the fixed bracket 18 plays an important supporting role and provides a stable foundation for subsequent operations. A lifting structure is provided on the fixed bracket 18, and the support plate 19 is slidably connected with the fixed bracket 18 through this lifting structure. The support plate 19 can move up and down on the fixed bracket 18, so that the height can be adjusted according to actual needs. The filter element is installed on the support plate 19, and the position is adjusted as the support plate 19 moves, so that the water source filtering operation can be performed more accurately. The filter element mainly includes a filter tank 71 and a filter cover 72. The filter cover 72 is connected to the filter tank 71, and the two together form a filter chamber, which is connected to the first water pump 32 through a connecting pipe. When the first water pump 32 draws the water source in the coal mining subsidence area, the water source first enters this filter chamber for preliminary filtration. The filter tank 71 is provided with multiple groups of filter slots 73, which can initially intercept larger impurities to prevent these impurities from entering the subsequent pipelines and equipment, causing pipeline blockage or equipment damage, and affecting the normal use of the device. At the same time, a filter screen 74 is also provided in the filter chamber, and the filter screen 74 can further filter out impurities such as fine particles and suspended matter in the water to improve the purity of the water source. A control module 23 is provided in the installation box 12. This control module 23 is the core control part of the entire monitoring device. It can control and coordinate various components. The control module 23 can use Mitsubishi FX5U series PLC. A wireless module is also provided on the control module 23, through which the control module 23 can be connected to the external monitoring system. Various data collected by the monitoring device can be transmitted to the external monitoring system in real time, and relevant personnel can remotely monitor and analyze the water environment of the coal mining subsidence area in real time. At the same time, the external monitoring system can also send instructions to the control module 23 through the wireless module to remotely control and adjust the monitoring device, thereby improving the intelligence and operation convenience of the monitoring device.

[0046] Embodiment 2: Based on the coal mining subsidence area water environment monitoring device provided in Embodiment 1 of the present application, Embodiment 2 of the present application proposes a coal mining subsidence area water environment monitoring device. This Embodiment 2 is only a preferred method of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. The second Embodiment 2 of the present invention will be further described below.

[0047] like Figure 4As shown, the cleaning assembly includes a cleaning box 601 and a liquid storage tank 602. The cleaning box 601 is located in the second protective cavity and connected to the workbench 11. The cleaning cover 603 is connected to the cleaning box 601, thereby forming a cleaning cavity. The cleaning cavity provides a relatively closed space for the cleaning of the detection probe 22, reducing the interference of external factors on the cleaning process. The liquid storage tank 602 is located in the first protective cavity. A special cleaning liquid is placed in the liquid storage tank 602, and the cleaning liquid can effectively remove various impurities and pollutants on the detection probe 22. A liquid inlet pipe 607 is provided on the top of the liquid storage tank 602, and a through hole 38 is provided on the first protective cover 34. One end of the liquid inlet pipe 607 is penetrated in the through hole 38, so that when the cleaning liquid is insufficient, the cleaning liquid can be added from the outside in time. At the same time, in order to prevent impurities from entering the liquid storage tank 602, a sealing plug 608 is also provided above the first protective cover 34, and the sealing plug 608 is stuck in the liquid inlet pipe 607 to ensure the sealing of the liquid storage tank 602. Two groups of nozzles 605 are arranged in the cleaning box 601. The two groups of nozzles 605 are symmetrically distributed. The symmetrical distribution allows the cleaning liquid to be evenly sprayed on the detection probe 22, ensuring the comprehensiveness and effectiveness of the cleaning. The liquid storage tank 602 is connected to the two groups of nozzles 605 through the third water pump 606. The third water pump 606 can pressurize the cleaning liquid in the liquid storage tank 602 and transport it to the nozzle 605, ensuring that the cleaning liquid is sprayed with sufficient pressure to perform a preliminary rinse on the detection probe 22. In this process, the cleaning liquid can quickly remove most of the impurities on the detection probe 22, laying the foundation for subsequent deep cleaning.

[0048] The difference between the second embodiment and the first embodiment is that a liquid inlet pipe 607 is provided on the liquid storage tank 602, and one end of the liquid inlet pipe 607 is inserted into the through hole 38 on the first protective cover 34. When the cleaning liquid in the liquid storage tank 602 is insufficient, the cleaning liquid can be added from the outside very conveniently. There is no need to disassemble the first protective cover 34 to add the cleaning liquid as in the first embodiment, which improves the convenience of operation. Because if the first protective cover 34 is disassembled every time the cleaning liquid is added, not only is the operation cumbersome, but the protective cover may also be damaged during the disassembly and installation process, affecting its protective effect. With the liquid inlet pipe 607 directly passing through the through hole 38, the staff can quickly and efficiently add the cleaning liquid without affecting the overall structure and protective performance of the monitoring device, ensuring that the cleaning component can always operate normally, and providing a strong guarantee for the stable operation of the water environment monitoring device in the coal mining subsidence area. The remaining conditions are consistent with the first embodiment, so this embodiment will not be repeated.

[0049] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
