Description

Technical Field

[0001] This invention relates to the field of water quality testing technology in mining areas, specifically to an auxiliary device for measuring water quality in subsidence areas. Background Technology

[0002] Mining subsidence is a unique landform formed by surface collapse caused by underground resource extraction. The accumulated water in these subsidence areas is closely linked to the groundwater system. Coal mining activities damage the surface morphology, leading to soil nutrient loss and damage to agricultural infrastructure. The accumulated water in subsidence areas is susceptible to infiltration of pollutants from surrounding areas, carrying heavy metals, nitrogen, phosphorus, and other substances into the water bodies. Long-term water accumulation can also alter the regional hydrological cycle, causing aquifer depletion or pollution spread, threatening the surrounding ecosystem and the safety of drinking water for residents. Therefore, water quality monitoring is the core basis for assessing the environmental risks of subsidence areas, formulating ecological restoration strategies, and is also a necessary means to ensure the sustainable use of water resources.

[0003] Currently, integrated in-situ detection devices are mainly used for monitoring. The detector and probe are carried by a buoyancy structure to measure parameters such as turbidity, dissolved oxygen, and conductivity in real time. They are also equipped with sampling tubes to collect water samples for laboratory analysis. They support in-situ sampling of complex media. For example, the thin-film diffusion gradient device, through the design of diffusion layer and fixed layer, can simultaneously obtain the bioavailable content and two-dimensional distribution information of more than 30 kinds of heavy metals / nutrients.

[0004] However, the water volume in the mining subsidence area varies greatly between the wet and dry seasons. Most existing buoy-type monitoring devices only consider the monitoring effect when the water volume is high. However, during the dry season, buoy-type monitoring devices may collide with the bottom of the subsidence area under the action of gravity, which may damage the monitoring devices or even cause the loss of monitoring data.

[0056] The working principle and beneficial effects of the above technical solution are: when disassembly is needed, the holding plate 21 is rotated to disassemble the threaded rod 22 from the threaded slot in the support rod 1.

[0057] In one embodiment: when the length of the support rod 1 is not enough, an extension rod 23 can be installed between the holding piece 2 and the support rod 1.

[0059] In one embodiment: when the subsidence area is deeper, another clamping part 75 can be selected, which comprises symmetrically arranged hard plates 756, between which a flexible bag 757 is arranged, one end of the flexible bag 757 is fixedly installed with a plurality of clamping plates 758, and the flexible bag 757 is fixedly installed with a sealing plug 759.

[0060] The working principle and beneficial effects of the above technical solution are: when the gas enters the clamping part 75, the flexible bag 757 will expand outward, at this time the clamping plate 758 will rotate under the extrusion of the sleeve 61, when the clamping plate 758 extends from the sleeve 61, the reset torsion spring at the clamping plate 758 will reset the clamping plate 755, and when it is retracted under external force, it cannot be retracted under the friction and clamping effect of the clamping plate 758, and the insertion rod can be arranged at one end of the clamping plate 758 close to the installation groove 754, and the insertion groove is arranged at the corresponding position of the sleeve 61, so that the stability effect is better, and the obliquely arranged clamping plate 755 can play a certain water breaking effect when the water flow speed is fast, dispersing the force of the water flow, so that the device is subjected to smaller lateral force and is less likely to be tilted. When disassembly is required, the sealing plug 759 is unscrewed, the gas in the flexible bag 757 is released, and the disassembly operation is completed.

[0061] In one embodiment: the size of the air pressure in the flexible bag 757 is the same as the size of the water pressure at the location.

[0062] The working principle and beneficial effects of the above technical solution are: the depth of the subsidence lake is measured before installation, and the size of the air pressure in the gas bag 74 is adjusted according to the depth, so that the size of the air pressure in the flexible bag 757 is equal to the size of the external water pressure after the installation of the device is completed, and the flexible bag 757 is in an inflated state at this time. When the dry season comes, the water depth of the subsidence lake will become shallower, at this time the size of the external water pressure will gradually decrease, the air pressure in the flexible bag 757 is greater than the external water pressure, which will make the flexible bag 757 expand more and have a larger contact area with the sleeve 61. When the depth decreases to a certain extent, the maximum volume will be reached, at which time the flexible bag 757 will be in contact with the bottom surface of the subsidence lake, thereby preventing shaking.

[0063] Working principle and use process: first, before installation, measure the depth of the subsidence lake, adjust the gas pressure in the gas bag 74 according to the depth, so that the device is installed after completion, the gas pressure in the flexible bag 757 is equal to the external water pressure, and the flexible bag 757 is in the inflated state at this time, when the dry season comes, the water depth of the subsidence lake will become shallow, at this time, the external water pressure will gradually decrease, the gas pressure in the flexible bag 757 is greater than the external water pressure, which will make the flexible bag 757 expand more and the contact area with the sleeve 61 larger, when the depth decreases to a certain extent, the maximum volume will be reached, at the maximum volume, the flexible bag 757 will contact the bottom surface of the subsidence lake, play the role of preventing shaking, according to the specific depth of the subsidence lake, select the number of extension rods 23 installed, then install the extension rods 23 on the corresponding threaded rods 22 and threaded grooves, which can adapt to subsidence lakes of different depths and improve the practicability.

[0064] Then, before installation, check whether each part is intact, continue installation if it is intact, replace it if it is not, then insert the support rod 1 into the subsidence lake, when the contact piece 4 contacts the bottom surface of the subsidence lake, it will be pressed upward to move, so that the insertion rod 6 extends out of the through hole on the contact piece 4 and is inserted into the bottom surface of the subsidence lake, when the water level of the subsidence lake decreases in the dry season, the monitoring mechanism 3 will slide down along the support rod 1, when it slides down to a certain position, the repulsive force between the magnetic plate 53 and the magnetic ring 32 will fix the monitoring mechanism 3 at a certain position and it will not slide down any more, which can prevent the monitoring mechanism 3 from being damaged, the buoy detector 31 can be any commonly used type that can be installed on the support rod 1, the magnetic ring 32 and the magnetic plate 53 need to be selected to have a magnetic force greater than the gravity of the buoy detector 31.

[0065] In addition, because the gas bag 74 is filled with gas, when the contact piece 4 moves up, it will squeeze the push piece 73, the push piece 73 moves to drive the sliding plate 72 to move along the limiting rod 71, when the limiting rod 71 moves to contact the gas bag 74, it will squeeze the gas bag 74, and then squeeze the gas in the gas bag 74 into the clamping piece 75, when the gas enters the clamping piece 75, it will enter the bag 752 through the proximal block 751, the bag 752 will expand, and then the distal block 753 will extend, when the distal block 753 extends to the sleeve 61, the clamping plate 755 will rotate under the extrusion of the sleeve 61, when the clamping plate 755 extends out of the sleeve 61, the reset torsional spring at the clamping plate 755 will drive the clamping plate 755 to reset, when it is retracted under external force, it cannot be retracted under the friction and clamping effect of the clamping plate 755, and the insertion rod can also be arranged at the end of the clamping plate 755 close to the installation slot 754, and the insertion slot is arranged at the corresponding position of the sleeve 61, so that the stability effect is better, at the same time, the obliquely arranged clamping plate 755 can play a certain water breaking effect when the water flow speed is fast, disperse the force of the water flow, so that the device is subjected to smaller lateral force and is less likely to be tilted.

[0066] Finally, when the settlement area is deep, the gas enters into the clamping part 75, which makes the flexible bag 757 expand outward, at this time, the clamping plate 758 rotates under the extrusion of the sleeve 61, when the clamping plate 758 extends from the sleeve 61, the reset torsional spring at the clamping plate 758 drives the clamping plate 755 to reset, when it is retracted under the external force, it cannot be retracted under the friction and the clamping effect of the clamping plate 758, and the insertion rod is arranged at the end of the clamping plate 758 close to the installation groove 754, and the insertion groove is arranged at the corresponding position of the sleeve 61, so that the stability effect is better, at the same time, the clamping plate 755 arranged obliquely can play a certain water breaking effect when the water flow speed is fast, disperses the force of the water flow, so that the device is subjected to smaller lateral force and is less likely to be tilted, when it is necessary to disassemble, the sealing plug 759 is unscrewed, the gas in the flexible bag 757 is discharged, and the disassembly operation is completed.
