Description

Technical Field

[0001] The present invention relates to the technical field of groundwater detection, in particular to a water quality detection device for groundwater investigation. Background Art

[0002] As a vital water resource, groundwater is crucial to human life, industrial production, and ecosystem stability. With the acceleration of industrialization and urbanization, groundwater faces serious challenges, including increased pollution risks and deteriorating water quality. Accurate and efficient groundwater quality testing is crucial for water resource conservation, its rational development and utilization, and ecological and environmental protection.

[0003] However, due to the different water quality conditions at different depths, multiple sampling is required. If sampling is done one at a time, a lot of time may be wasted. In addition, due to the large amount of sediment in some groundwater, abnormal test results may occur during groundwater sampling, resulting in data errors. This patent is to provide a water quality detection device for groundwater investigation to alleviate the above technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when sampling, due to the different water quality conditions at different depths, multiple samplings are required. If sampling is done one by one, a lot of time may be wasted. In addition, since some groundwater contains a large amount of sediment, abnormal test results may occur during groundwater sampling, resulting in data errors. A water quality detection device for groundwater investigation is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The water quality detection device for groundwater investigation includes a fixed tube and an annular box, wherein an inner rack is provided inside the fixed tube, and the inner rack is meshed with a long gear, and the long gear is transmitted to a rotating rod, and the rotating rod is fixedly connected to the second bevel gear at one end away from the connecting tube, and the second bevel gear is meshed with the first bevel gear, and one end of the first bevel gear is fixedly connected to a cam, and a sampling mechanism for groundwater sampling is provided inside the annular box, and the sampling mechanism includes a filter box arranged on the side of the annular box, and a sample storage box is slidably connected to the filter box, one end of the sample storage box is fixedly connected to a spring, and the end of the sample storage box away from the spring is fixedly connected to a tilt bar, and a cleaning ring for cleaning its surface is provided on the surface of the filter box, and a short block is fixedly connected to the side of the cleaning ring, and the short block is fixedly connected to the U-shaped block, and the U-shaped block is rotatably connected to a support bar, and the support bar is eccentrically arranged on the surface of the disc block, and the disc block is transmission-connected to the large-circle rotating block.

[0007] The above technical solution further includes:

[0008] A long column is fixedly connected to one side of the first bevel gear, and a cam is fixedly connected to the end of the long column away from the first bevel gear. A large circle rotating block is sleeved on the surface of the long column, and the long gear is transmission-connected to the first belt, and the end of the first belt away from the long gear is movably connected to the rotating rod, and the long gear is rotationally connected to the connecting pipe. A sliding track for sliding short blocks is provided on the surface of the filter box, and multiple groups of holes for water inlet are provided on the surface of the filter box. The disc block is transmission-connected to the second belt, and the end of the second belt away from the disc block is transmission-connected to the large circle rotating block.

[0009] A connecting bar is fixedly connected to the side surface of the connecting pipe, and the connecting bar is rotatably connected to the first bevel gear.

[0010] The side of the annular box is provided with multiple groups of sampling mechanisms for sampling.

[0011] A sample storage box is slidably connected to the inside of the annular box, and a detection port for detecting water samples is provided on one side of the sample storage box. A plurality of magnetic blocks for adsorbing the sides of the sample storage box are provided inside the annular box. The sample storage box is slidably connected to the annular box, which facilitates the adjustment of the position of the sample storage box at different stages. Whether it is extending it to receive water samples during sampling or returning it to its place after sampling for subsequent testing, this sliding connection design can be flexibly implemented. The detection port is provided on one side of the sample storage box, so that the water sample collection and testing process are closely connected. Once the sampling is completed, the water sample can be tested directly through the detection port without the need for complicated transfer operations, which greatly improves the detection efficiency, reduces the risk of contamination and time loss that may be caused by the transfer of water samples, and provides convenience for quickly obtaining accurate water quality test results.

[0012] The bottom of the annular box is threadedly connected to a chassis. This threaded connection allows for convenient removability. After groundwater sampling and testing, the chassis can be easily unscrewed, allowing for easy cleaning and maintenance of components inside the annular box, such as the sample storage box. This design effectively prevents damage to the device from impurities and microorganisms in residual water samples after long-term use, thereby extending its service life. Furthermore, disassembly of the chassis facilitates replacement or repair of internal components of the annular box, reducing maintenance costs and complexity.

[0013] The annular box is equipped with multiple sets of sample storage covers for shielding the openings of the sample storage box. The presence of the sample storage covers provides reliable protection for water sample preservation. After the sample storage box completes water sample collection, the sample storage covers can promptly cover the openings, effectively preventing the water sample from being disturbed by external environmental factors such as dust and other impurities during subsequent transportation and testing. This ensures the purity of the water sample and ensures that the test results truly reflect the groundwater quality.

[0014] A square sampling cavity for the sliding of the sample storage box is provided inside the filter box.

[0015] A button on one side of the fixed tube controls the rotation of the long gear. This greatly simplifies the device's operation. Instead of using complex manual mechanical operations to rotate the long gear, the inspector simply presses a button to rotate the gear, thereby controlling the expansion and contraction of the connecting tube and a series of subsequent mechanical actions related to sampling.

[0016] The annular box is rotatably connected to the disc block.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, groundwater samples of different depths can be obtained simultaneously during a single operation, avoiding the cumbersome process of the traditional method of multiple probes for separate sampling at different depths. Moreover, after the sampling is completed, the water sample can flow directly into the detection port for testing. This integrated design of multi-depth synchronous sampling and instant detection greatly reduces the time consumed by the entire detection process and significantly improves the efficiency of groundwater quality testing. The tester does not need to go back and forth multiple times to take samples at different depths, and can complete a comprehensive test of the groundwater quality at different depths in a short time.

[0019] 2. In this invention, by providing three sets of cleaning rings on the annular box to clean the filter cartridge surface back and forth, it effectively prevents large amounts of sediment from entering the filter cartridge, thereby preventing sediment from interfering with the sampling and testing process. This design ensures the purity and representativeness of the water samples, making the test results more accurate and reliable. In actual testing, repeating tests due to abnormal test results consumes a lot of time and resources. By effectively preventing sediment, the occurrence of test errors caused by sediment is reduced, avoiding unnecessary repeated testing processes. BRIEF DESCRIPTION OF THE DRAWINGS

The support bar 13 is eccentrically arranged on the surface of the disc block 12, and the disc block 12 is transmission-connected to the large-circle rotating block 20.

[0031] In one embodiment, for the above-mentioned first bevel gear 9, a long column 11 is fixedly connected to one side of the first bevel gear 9, and a cam 19 is fixedly connected to the end of the long column 11 away from the first bevel gear 9. A large-circle rotating block 20 is sleeved on the surface of the long column 11. The long gear 5 is transmission-connected to the first belt 6, and the end of the first belt 6 away from the long gear 5 is movably connected to the rotating rod 7.

The disc block 12 is transmission-connected to the second belt 18, and the end of the second belt 18 away from the disc block 12 is transmission-connected to the large-circle rotating block 20.

[0032] In one embodiment, for the above-mentioned connecting pipe 2 , a connecting bar 10 is fixedly connected to the side surface of the connecting pipe 2 , and the connecting bar 10 is rotatably connected to the first bevel gear 9 .

[0033] In one embodiment, for the annular box 3 , multiple groups of sampling mechanisms for sampling are provided on the side of the annular box 3 .

[0034] In one embodiment, for the above-mentioned annular box 3, a sample storage box 22 is slidably connected inside the annular box 3, a detection port 23 for detecting water samples is provided on one side of the sample storage box 22, and multiple groups of magnetic blocks 24 for adsorbing the side of the sample storage box 22 are provided inside the annular box 3.

[0035] In this embodiment, the sample storage box 22 is slidably connected to the annular box 3, which facilitates the adjustment of the position of the sample storage box 22 at different stages. Whether it is extended to receive the water sample during sampling or returned to its original position after sampling for subsequent testing, this sliding connection design can be flexibly implemented. The detection port 23 is set on one side of the sample storage box 22, so that the water sample collection and testing process are closely connected. Once the sampling is completed, the water sample can be tested directly through the detection port 23 without complicated transfer operations, which greatly improves the detection efficiency, reduces the risk of contamination and time loss that may be caused by the transfer of water samples, and provides convenience for quickly obtaining accurate water quality test results.

[0036] In one embodiment, for the annular box 3, the bottom of the annular box 3 is threadedly connected to a base plate 25. The base plate 25 and the annular box 3 are threadedly connected, which is convenient for detachability.

[0037] In this embodiment, after groundwater sampling and testing are complete, the chassis 25 can be easily unscrewed, facilitating cleaning and maintenance of components within the annular box 3, including the sample storage box 22. This design effectively prevents damage to the device from impurities and microorganisms remaining in the water sample after long-term use, thereby extending the device's service life. Furthermore, when components within the annular box 3 need to be replaced or repaired, removing the chassis 25 facilitates operation, reducing maintenance costs and difficulty.

[0038] In one embodiment, for the annular box 3 , a plurality of groups of sample storage covers 27 for covering the opening of the sample storage box 22 are provided inside the annular box 3 .

[0039] In this embodiment, the presence of the sample storage cover 27 provides reliable protection for water sample preservation. After the sample storage box 22 completes water sample collection, the sample storage cover 27 can promptly cover its opening, effectively preventing the water sample from being disturbed by external environmental factors such as dust and other impurities during subsequent transportation and testing. This ensures the purity of the water sample and ensures that the test results can truly reflect the groundwater quality.

[0040] In one embodiment, for the above-mentioned filter box 8, a square sampling cavity 28 for the sample storage box 22 to slide is provided inside the filter box 8.

[0041] In one embodiment, for the above-mentioned fixing tube 1, a button for controlling the rotation of the long gear 5 is provided on one side of the fixing tube 1. The provision of the button greatly simplifies the operation process of the device.

[0042] In this embodiment, the inspector does not need to perform complicated manual mechanical operations to rotate the long gear 5. Instead, he or she only needs to press a button to rotate the long gear 5, thereby controlling the extension and retraction of the connecting tube 2 and a subsequent series of mechanical actions related to sampling.

[0043] In one embodiment, for the annular box 3 , the annular box 3 is rotatably connected to the disc block 12 .

[0044] The water quality detection device for groundwater survey in the present invention is first carried by a groundwater survey water quality detection personnel to the area to be detected. Then the detection personnel hold one end of the fixed pipe 1 with their hands and then control the long gear 5 to rotate. The long gear 5 rotates and engages with the rack 4 inside the fixed pipe 1, thereby causing the connecting pipe 2 to slide out of the fixed pipe 1. Figure 1 For example, after the long gear 5 rotates and meshes with the rack 4 inside the tube, the connecting tube 2 extends one meter from the fixed tube 1. When the connecting tube 2 extends one-third of a meter from the fixed tube 1, the connecting tube 2, while moving, utilizes the meshing of the long gear 5 and the rack 4 inside the tube to drive the rotating rod 7 to rotate via the first belt 6. The rotating rod 7 rotates, which in turn meshes with the first bevel gear 9 through the second bevel gear 901. The rotation of the first bevel gear 9 drives the cam 19 via the long column 11.

[0045] Three sampling mechanisms are located inside the annular box 3. When the cam 19 rotates one-third of the way, it pushes the tilt bar 21 of one of the sampling mechanisms. The tilt bar 21 then slides, driving the sample storage box 22 to slide within the square sampling cavity 28 inside the filter box 8. The sliding of the tilt bar 21 drives the sample storage box 22 to press against the spring 26, exposing the sample storage box 22 inside the filter box 8. Water in this area then flows into the interior of the sample storage box 22.

[0046] When the long gear 5 continues to mesh with the rack 4 in the tube, the cam 19 continues to rotate and disengages from the pressure on the tilt bar 21. At this time, the tilt bar 21 is no longer squeezed, and the spring 26 pushes the sample box 22 in the opposite direction to slide, thereby blocking the surface of the sample box 22 with the sample cover 27. The sample box 22 is also attracted by the magnetic block 24 to ensure that the sampled water flow is not lost. Similarly, the present invention is provided with three groups of sample boxes 22 for sampling, which have the same effect as pushing the tilt bar 21. When water samples from other groups are collected, the sample boxes 22 of the other groups will be pushed by the sample cover 27 to block the sample boxes 22.

[0047] In addition, when the cam 19 rotates, it will use the large-circle rotating block 20 to drive the second belt 18 to rotate. The rotation of the second belt 18 will penetrate the annular box 3 and drive the disc block 12 to rotate. The disc block 12 eccentrically drives the support bar 13 to rotate, thereby pushing the short block 15 back and forth to slide on the surface of the sliding track 16. When the short block 15 moves back and forth on the surface of the sliding track 16, it will use the cleaning ring 17 to clean the surface of the filter box 8 back and forth, thereby preventing mud and sand from entering the interior of the filter box 8 and avoiding sampling anomalies. Similarly, two other sets of cleaning rings 17 are set above the annular box 3 to clean the surface of the filter box 8 to prevent sampling anomalies at any water depth.

[0048] After the sampling is completed, the water flows into the detection port 23 to check the water sample in the water area. Then, after the detection value is recorded, the rack 4 in the control tube and the long gear 5 are engaged in reverse, so that the connecting tube 2 is retracted into the interior of the fixed tube 1. After reaching the ground, the chassis 25 is removed, and the sample storage box 22 of multiple groups of samples can be wiped clean to prevent internal damage and affect the next detection.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
