Description

Technical Field

[0001] The present invention relates to the technical field of groundwater environment monitoring, and in particular to a groundwater environment monitoring and sampling integrated device and method. Background Art

[0002] Groundwater environmental monitoring is the basis for groundwater pollution prevention and control, and is also an important basis for understanding the status and changing trends of groundwater environmental quality; groundwater testing items usually include ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total hardness, pH value, oxygen consumption, total mineralization, potassium, sodium, calcium, magnesium, bicarbonate, sulfate, chloride ion, phenol, cyanide, mercury, arsenic, cadmium, total chromium, fluoride, oil, coliform group, total bacteria, etc. The selection of these items depends on the specific situation of groundwater and the purpose of testing. In the specific monitoring process, the water samples taken need to be measured by monitoring equipment according to their physical or chemical properties to accurately evaluate the groundwater quality.

[0003] When testing groundwater, the methods commonly used are: wellhead observation method, borehole logging method, environmental monitoring well method, groundwater level probe method, and geophysical survey method. From the perspective of practical application, the environmental monitoring well method and the groundwater level probe method are two more commonly used and effective methods. Among them, the environmental monitoring well method is a method of regularly monitoring the groundwater level and water quality indicators in the well by setting up environmental monitoring wells; the groundwater level probe method is a method of measuring the height of the groundwater level by using a water level probe.

[0004] The patent document with publication number CN113237700A discloses an integrated mobile equipment for groundwater sampling and detection, including a base plate, a plurality of columns are fixedly connected to the upper surface of the base plate, and a fixed plate is fixedly connected between the columns, a side plate is fixedly connected to the upper surface of the base plate, a winding drum is movably connected to the upper surface of the fixed plate, and a connecting pipe is wrapped around the outer surface of the winding drum, a transfer pipe is fixedly connected to one end of the connecting pipe, and a plug hole is opened on the top of the winding drum.

[0005] However, when traditional groundwater environment monitoring equipment is in use, the sampling device it is equipped with has a simple structure, which can easily cause water sample confusion when sampling groundwater at different depths, resulting in inaccurate groundwater environment monitoring results.

[0006] For example: after sampling groundwater at a low water level, the water sample must be extracted first, and then the water sample at a high water level is extracted. In this case, the water sample at the low water level will fill the extraction tube, which will mix the water samples at different water levels and affect the monitoring data. The traditional treatment is to use backflow and multiple extraction methods to solve the problem at the new water level to be tested. The backflow is to use reverse thrust to push the water sample sampled last out of the pipe, and the multiple extraction method is to extract and discharge the old water sample in the pipe before obtaining the new water sample, and then extract the remaining water sample in the pipe after it is discharged. The above two methods require the sampling head to reach the new water level before operation, and the above operations will cause water flow chaos at the new water level, which will affect the sampling results to a certain extent. Summary of the invention

[0007] The present invention discloses an integrated groundwater environment monitoring and sampling device and method, aiming to solve the technical problem that the sampling device of the conventional groundwater environment monitoring device is simple in structure when in use, which easily causes confusion of water samples when sampling groundwater at different depths, thus leading to inaccurate groundwater environment monitoring results.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions: A groundwater environment monitoring and sampling integrated equipment, comprising a mounting frame, a connecting seat is provided on an outer wall of one side of the mounting frame close to the bottom, a top frame is provided on an outer wall of one side of the mounting frame close to the top, and further comprising: a lifting mechanism: the lifting mechanism is arranged on the top frame; a sampling mechanism: the sampling mechanism comprises a collection rod connected to the lifting mechanism, four equidistantly distributed mounting rods are arranged on the circumferential outer wall of the collection rod, a sampling cup is arranged at one end of the mounting rod, the interior of the mounting rod is arranged as a hollow structure, a circular groove is provided on the inner wall of the collection rod, the sampling cup is connected to the interior of the circular groove through the hollow structure inside the mounting rod, four equidistantly distributed collection ports are also provided on the circumferential outer wall of the collection rod, a filter is installed on the inner wall of the collection port, the collection port is also connected to the interior of the circular groove, and the collection port and the sampling cup are respectively located on both sides of the circular groove; an active limiting mechanism: the active limiting mechanism is arranged on an outer wall of one side of the top frame; a start-stop mechanism: the start-stop mechanism is connected to the collection rod.

[0009] In this solution, the sampling mechanism is composed of four sampling cups and a collection port. During sampling, the collection rod can reach different water levels for sampling under the action of the lifting mechanism, and the multiple sampling cups arranged on the collection rod can perform range sampling at the current water level to ensure that the current water level data is more accurate. At the same time, the multiple sampling cups and the collection port are coordinated. After the collection rod is lowered to a suitable position, the switches can be turned on at the same time under the action of the start-stop mechanism. The sampling processes of the multiple sampling heads are carried out synchronously, and no mutual interference will be formed in their respective sampling processes, thereby avoiding inaccurate sampling data.

[0010] In a preferred embodiment, a wedge rod is provided on one side of the sampling cup close to the mounting rod, a buckle groove is provided on the top of the mounting rod, a buckle block is provided on the inner wall of the buckle groove, and the bottom of the buckle block passes through the buckle groove and is buckled onto the top outer wall of the wedge rod.

[0011] The buckle block cooperates with the wedge rod to lock the sampling cup inserted into the mounting rod, so that the sampling cup can be quickly disassembled and assembled. After the sampling is completed, it can be collected and installed more efficiently, facilitating the efficient implementation of the entire sampling process.

[0012] In a preferred embodiment, the lifting mechanism includes a mounting hole arranged on the top frame, and a first unwinding roller and a second unwinding roller are connected to the inner wall of the mounting hole through a bearing, a first connecting rope is wrapped around the first unwinding roller, and a second connecting rope is wrapped around the second unwinding roller, a connecting rod is connected to the bottom end of the first connecting rope, and the connecting rod is screwed to the top end of the collecting rod, and a crank is connected to the outer wall of one side of the top frame through a bearing, and one end of the crank is connected to one side of the first unwinding roller.

[0013] Through the set lifting mechanism, the collecting rod can be towed and raised to a suitable height in the groundwater. In specific use, the bottom end of the first connecting rope is first installed on the collecting rod through the connecting rod, and then the groundwater of different water depths is sampled from top to bottom. After collecting the current water depth, it is raised and collected under the action of the crank, and then the lower layer water samples are continued to be collected. In this way, not only can water samples be collected in a larger range, but also the sequential sampling from top to bottom can avoid the interference of the earlier collection work with the later collection work.

[0014] In a preferred embodiment, the movable limiting mechanism includes a mounting block arranged on the outer wall of one side of the top frame, a limiting groove is provided on the inner wall of the mounting block, an outer gear sleeve is slidably connected to the inner wall of the limiting groove, an inner gear sleeve is provided on the outer wall of the crank handle, the outer gear sleeve and the inner gear sleeve are meshed, the first unwinding roller is provided with a first linkage roller, the second unwinding roller is provided with a second linkage roller, the outer walls of the first linkage roller and the second linkage roller are provided with the same transmission belt, and the diameter ratio of the first unwinding roller and the second unwinding roller is consistent with the diameter ratio of the first linkage roller and the second linkage roller.

[0015] Different lifting heights can be limited by the set active limiting mechanism. In the specific limiting process, the outer gear sleeve is slid along the limiting groove to the inside of the mounting block. In this process, the tooth grooves on the inner side of the outer gear sleeve are engaged and locked with the tooth grooves on the outer side of the inner gear sleeve, temporarily limiting the rotation and retraction of the crank handle and the first unwinding roller, making it convenient for the collection rod to hover at the specified water depth for sampling.

[0016] In a preferred scheme, the start-stop mechanism includes a sliding sleeve arranged on the outer wall of the collection rod, an inner rod is slidably connected to the inner wall of the circular groove, the inner rod is provided with connecting holes distributed at equal distances, the top of the inner rod is connected with a connecting rod, and movable plates are slidably connected to the outer walls on both sides of the collection rod near the top, and the same connecting pad is installed between the two movable plates, the top of the connecting rod is connected to the bottom outer wall of the connecting pad, the inner side of the sliding sleeve is connected to the movable plate, a connecting hoop is movably connected to the outer wall of the sliding sleeve, the bottom end of the second connecting rope is connected to the connecting hoop, a fixing block is provided on the bottom outer wall of the top frame, an electric telescopic rod is installed on the outer wall of one side of the fixing block, and one end of the rod body of the electric telescopic rod is connected to a retaining hoop, and the retaining hoop abuts against the lead-out end of the second connecting rope.

[0017] The start-stop mechanism set up can cooperate with the collecting rod to complete the task of precise sampling. In specific use, when the collecting rod is at an appropriate depth under the action of the lifting mechanism, the movable limiting mechanism is first used to limit the crank handle and the first unwinding roller, and then the electric telescopic rod is started. The extension and contraction of the electric telescopic rod drives the retaining hoop to squeeze the straightened second connecting rope, thereby driving the inner rod connected to the bottom end of the second connecting rope to move upward from the inside of the connecting hole, and finally drives the connecting hole on the inner rod to correspond to the collecting port and the hollow structure inside the mounting rod. The groundwater at the current water level can enter from the collecting port, and then enter into the sampling cup through the connecting hole and the hollow structure inside the mounting rod to complete the fixed-point sampling. In this process, the water sample takes little movement and will not cause surges at different water layer depths.

[0018] In a preferred scheme, the top of the mounting frame is connected to the mounting base by a hinge, and two sliding rods are provided on one side of the mounting base, and the top frame is slidably connected to the outer walls of the two sliding rods, and holes are provided on the outer walls on both sides of the mounting base, and the outer walls of the mounting frame on both sides near the top are slidably connected with limiting plug rods, and the plug holes are adapted to the limiting plug rods, and a movable buckle is provided on the outer wall of one side of the mounting frame, and the movable buckle is used in conjunction with the connecting seat, and two movable rods are slidably connected to the inner side wall of the mounting frame near the bottom, and support pads are installed at the bottom of the two movable rods, and the bottoms of the two support pads are flush with the bottom plane of the mounting frame, a handle is provided on the top outer wall of the mounting frame, and two storage racks are also provided on the outer wall of one side of the mounting frame.

[0019] Through the movable mounting base, connecting base and movable rod, quick folding and unfolding effects can be achieved, and the transfer process after use is relatively convenient. At the same time, the two storage racks arranged on the mounting rack are used in conjunction with the collecting rod. After the collecting work of the collecting rod is completed, it can be placed in it for fixed storage, avoiding the problem of not being able to assemble in time for the next use. Among them, one collecting rod can be stored separately in each of the two storage racks, and when one of them fails during assembly and use, it can be replaced nearby.

[0020] A method for using a groundwater environment monitoring and sampling integrated device comprises the following steps: S1: First, check the accessories on the equipment, and move the equipment to the designated groundwater monitoring well according to the sampling and monitoring requirements. At the same time, open the wellhead of the monitoring well and move the equipment near the wellhead of the monitoring well; S2: Then, the mounting base and the top frame are supported to a horizontal position, and the limiting plug rod is used to limit the position with the plug hole, and then the connecting base is turned over and fixed flat on the ground, and then the two movable rods are pulled out from the inside of the mounting frame and supported to the outside of the monitoring well, so that the top frame on the equipment is located directly above the wellhead of the monitoring well; S3: Next, the collection rod is taken out from the storage rack, the sampling cup is assembled onto the collection rod in sequence, and then the collection rod is assembled onto the bottom end of the first connecting rope, and at the same time, the monitoring device placed in the mounting rack is taken out; S4: Finally, the integrated groundwater environment monitoring and sampling equipment is used to collect water samples at different depths inside the monitoring well.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The invention discloses an integrated groundwater environment monitoring and sampling device and method, which are mainly applied to scenarios where traditional groundwater environment monitoring equipment is equipped with a simple sampling device when in use, which easily causes confusion of water samples when sampling groundwater at different depths, resulting in inaccurate groundwater environment monitoring results.

[0037] Reference Figures 1 to 12 , an integrated groundwater environment monitoring and sampling device, comprising a mounting frame 1, a lifting mechanism, a sampling mechanism, a movable limiting mechanism and a start-stop mechanism, a connecting seat 2 is provided on the outer wall of one side of the mounting frame 1 near the bottom, a top frame 4 is provided on the outer wall of one side of the mounting frame 1 near the top, and the lifting mechanism is arranged on the top frame 4; the sampling mechanism comprises a collection rod 18 connected to the lifting mechanism, four equidistantly distributed mounting rods are provided on the circumferential outer wall of the collection rod 18, a sampling cup 26 is provided at one end of the mounting rod, the interior of the mounting rod is arranged as a hollow structure, the inner wall of the collection rod 18 is provided with a circular groove, the sampling cup 26 is connected with the inside of the circular groove through the hollow structure inside the mounting rod, and four equidistantly distributed collection ports are also provided on the circumferential outer wall of the collection rod 18, a filter screen 27 is installed on the inner wall of the collection port, the collection port is also connected with the inside of the circular groove, and the collection port and the sampling cup 26 are respectively located on both sides of the circular groove; the movable limiting mechanism is arranged on the outer wall of one side of the top frame 4; the start-stop mechanism is connected to the collection rod 18.

[0038] Specifically, the sampling mechanism is composed of four sampling cups 26 and a collection port. During sampling, the collection rod 18 can reach different water levels for sampling under the action of the lifting mechanism, and the multiple sampling cups 26 arranged on the collection rod 18 can be sampled within the current water level range to ensure that the current water level data is more accurate. At the same time, the multiple sampling cups 26 are coordinated with the collection port. After the collection rod 18 is lowered to a suitable position, the switches can be turned on at the same time under the action of the start-stop mechanism. The sampling processes of the multiple sampling heads are carried out synchronously, and no mutual interference will be formed in their respective sampling processes, thereby avoiding inaccurate sampling data.

[0039] Among them, the four sampling cups 26 and the four collecting ports arranged on the outer wall of the collecting rod 18 are all arranged in a centrally symmetrical manner. The centrally symmetrically arranged sampling cups 26 and collecting ports can balance the weight of the collecting rod 18 on the left and right, ensuring that the collecting rod 18 can be kept vertically and not tilted as much as possible when it goes down to collect water samples, thereby avoiding instability in the sampling process.

[0040] Reference Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11In a preferred embodiment, a wedge rod is provided on one side of the sampling cup 26 close to the mounting rod, a buckle groove is provided on the top of the mounting rod, a buckle block 32 is provided on the inner wall of the buckle groove, and the bottom of the buckle block 32 passes through the buckle groove and is buckled on the top outer wall of the wedge rod.

[0041] Specifically, the buckle block 32 provided in this embodiment cooperates with the wedge rod to lock the sampling cup 26 inserted into the mounting rod, thereby achieving quick disassembly and assembly of the sampling cup 26. After the sampling is completed, it can be collected and installed more efficiently, facilitating the efficient implementation of the entire sampling process.

[0042] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 In a preferred embodiment, the lifting mechanism includes a mounting hole arranged on the top frame 4, and the first unwinding roller 9 and the second unwinding roller 10 are connected to the inner wall of the mounting hole through a bearing, the first unwinding roller 9 is wrapped with a first connecting rope, and the second unwinding roller 10 is wrapped with a second connecting rope, the bottom end of the first connecting rope is connected to a connecting rod 23, and the connecting rod 23 is screwed to the top end of the collecting rod 18, and a crank 11 is connected to the outer wall of one side of the top frame 4 through a bearing, and one end of the crank 11 is connected to one side of the first unwinding roller 9.

[0043] Specifically, the lifting mechanism provided in this embodiment can pull the collecting rod 18 to rise or fall to a suitable height in the groundwater. During specific use, the bottom end of the first connecting rope is first installed on the collecting rod 18 through the connecting rod 23, and then the groundwater of different depths is sampled from top to bottom. After sampling the current water depth, the rod is raised and collected under the action of the crank 11, and then the water sample of the lower layer is continued to be collected. In this way, not only can water samples be collected in a larger range, but also the sequential sampling from top to bottom can avoid the interference of the earlier collection work with the later collection work.

[0044] Reference Figure 6 and Figure 7 In a preferred embodiment, the movable limiting mechanism includes a mounting block 19 arranged on the outer wall of one side of the top frame 4, a limiting groove 22 is provided on the inner wall of the mounting block 19, an outer gear sleeve 21 is slidably connected to the inner wall of the limiting groove 22, an inner gear sleeve 20 is provided on the outer wall of the crank 11, the outer gear sleeve 21 and the inner gear sleeve 20 are meshed, the first unwinding roller 9 is provided with a first linkage roller, the second unwinding roller 10 is provided with a second linkage roller, the outer walls of the first linkage roller and the second linkage roller are provided with the same transmission belt 17, and the diameter ratio of the first unwinding roller 9 and the second unwinding roller 10 is consistent with the diameter ratio of the first linkage roller and the second linkage roller.

[0045] Specifically, different lifting heights can be limited by the set active limiting mechanism. In the specific limiting process, the outer gear sleeve 21 is slid along the limiting groove 22 to the inside of the mounting block 19. In this process, the tooth grooves on the inner side of the outer gear sleeve 21 are meshed and locked with the tooth grooves on the outer side of the inner gear sleeve 20, temporarily limiting the rotation and retraction of the crank 11 and the first unwinding roller 9, making it convenient for the collecting rod 18 to hover at the specified water depth for sampling.

[0046] It should be noted that, since the diameter ratio of the first unwinding roller 9 and the second unwinding roller 10 is consistent with the diameter ratio of the first linkage roller and the second linkage roller, during the retraction and release of the first connecting rope, the second connecting rope can also be retracted and released synchronously.

[0047] Reference Figure 8 , Fig. 9 , Fig.10 and Fig.11 In a preferred embodiment, the start-stop mechanism includes a sliding sleeve 24 arranged on the outer wall of the collection rod 18, an inner rod 28 is slidably connected to the inner wall of the circular groove, and the inner rod 28 is provided with connecting holes 31 distributed at equal distances, and the top of the inner rod 28 is connected to a connecting rod 30, and movable plates are slidably connected to the outer walls of both sides of the collection rod 18 near the top, and the same connecting pad 29 is installed between the two movable plates, and the top of the connecting rod 30 is connected to the bottom outer wall of the connecting pad 29, the inner side of the sliding sleeve 24 is connected to the movable plate, and a connecting hoop 25 is movably connected to the outer wall of the sliding sleeve 24, and the bottom end of the second connecting rope is connected to the connecting hoop 25, and a fixing block 14 is provided on the bottom outer wall of the top frame 4, and an electric telescopic rod 15 is installed on the outer wall of one side of the fixing block 14, and a retaining hoop 16 is connected to one end of the rod body of the electric telescopic rod 15, and the retaining hoop 16 is abutted against the lead-out end of the second connecting rope.

[0048] Specifically, the start-stop mechanism set up can cooperate with the collection rod 18 to complete the precise sampling task. During specific use, when the collection rod 18 is at a suitable depth under the action of the lifting mechanism, the movable limiting mechanism is first used to limit the crank 11 and the first unwinding roller 9, and then the electric telescopic rod 15 is started. The extension and contraction of the electric telescopic rod 15 drives the retaining hoop 16 to squeeze the straightened second connecting rope, thereby driving the inner rod 28 connected to the bottom end of the second connecting rope to move upward from the inside of the connecting hole 31, and finally drives the connecting hole 31 on the inner rod 28 and the collection port and the hollow structure inside the mounting rod to correspond. The groundwater at the current water level can enter from the collection port, and then enter the sampling cup 26 through the connecting hole 31 and the hollow structure inside the mounting rod to complete the fixed-point sampling. In this process, the water sample takes little action and will not cause surges at different water layer depths.

[0049] It should be noted that the filter 27 provided inside the collection port can isolate impurities in the water body to prevent the impurities from entering the collection port and causing blockage.

[0050] Reference Figure 1 , Figure 2 and Fig.12 In a preferred embodiment, the top of the mounting frame 1 is connected to a mounting base 12 by a hinge, and two sliding bars 7 are provided on one side of the mounting base 12. The top frame 4 is slidably connected to the outer walls of the two sliding bars 7. Plug holes 13 are provided on the outer walls on both sides of the mounting base 12. Limiting plug rods 33 are slidably connected to the outer walls on both sides of the mounting frame 1 near the top, and the plug holes 13 are adapted to the limiting plug rods 33. A movable buckle 34 is provided on the outer wall of one side of the mounting frame 1, and the movable buckle 34 is used in conjunction with the connecting seat 2. Two movable rods 6 are slidably connected to the inner side wall of the mounting frame 1 near the bottom, and support pads 35 are installed at the bottom of the two movable rods 6. The bottoms of the two support pads 35 are flush with the bottom plane of the mounting frame 1. A handle 3 is provided on the top outer wall of the mounting frame 1, and two storage racks 8 are also provided on the outer wall of one side of the mounting frame 1.

[0051] Specifically, through the movable mounting seat 12, the connecting seat 2 and the movable rod 6, the quick folding and unfolding effects can be achieved, and the use process and the transfer process are relatively convenient. At the same time, the two storage racks 8 arranged on the mounting rack 1 are used in conjunction with the collecting rod 18. After the collecting work of the collecting rod 18 is completed, it can be placed therein for fixed-point storage, avoiding the problem of not being able to assemble in time for the next use. Among them, one collecting rod 18 can be stored separately in each of the two storage racks 8, and when one of them fails during assembly and use, it can be replaced nearby.

[0052] It should be noted that the equipment used to monitor and collect water samples in the present solution is installed separately from the mounting frame 1. During specific use, the monitoring equipment stored therein can be taken out for monitoring, and then placed back into the mounting frame 1 for storage after use. Due to the variety of models of monitoring equipment, they are not shown in the accompanying drawings, and the monitoring equipment can be conventional monitoring equipment in the field.

[0053] A method for using a groundwater environment monitoring and sampling integrated device comprises the following steps: S1: First, check the accessories on the equipment, and move the equipment to the designated groundwater monitoring well according to the sampling and monitoring requirements. At the same time, open the wellhead of the monitoring well and move the equipment near the wellhead of the monitoring well; S2: Then, the mounting base 12 together with the top frame 4 is supported to a horizontal position, and the limiting plug rod 33 is used to limit the position in cooperation with the plug hole 13, and then the connecting base 2 is turned over and fixed flat on the ground, and then the two movable rods 6 are pulled out from the inside of the mounting frame 1, and supported to the outside of the monitoring well, so that the top frame 4 on the equipment is located directly above the wellhead of the monitoring well; S3: Next, the collection rod 18 is taken out from the storage rack 8, the sampling cup 26 is assembled to the collection rod 18 in sequence, and then the collection rod 18 is assembled to the bottom end of the first connecting rope. At the same time, the monitoring device (not shown in the figure) placed in the mounting rack 1 is taken out; S4: Finally, the integrated groundwater environment monitoring and sampling equipment is used to collect water samples at different depths inside the monitoring well. At the same time, the taken-out monitoring equipment (not shown in the figure) is used to conduct on-site monitoring and analysis of the collected water samples, and finally accurate data of this monitoring and sampling is obtained.
