AI Technical Summary
In existing groundwater pollution detection devices, the difference in rotation speed of synchronous motors causes unstable movement of the support plate, affecting the sampling process of the water intake metal pipe. Furthermore, the water intake depth is limited by the length of the hollow pipe and the moving distance of the support plate, making it impossible to achieve flexible depth control.
The system employs a first servo motor and a second servo motor in conjunction with a first bevel gear and a second bevel gear. Synchronous rotation enhances the stability of the lifting plate, and a detachable extension rod extends the drilling depth. The number of extension rod sections can be flexibly installed to accommodate sample collection at different depths.
It achieves stable movement of the lifting plate, enhances flexible control of sampling depth, and can extend drilling depth as needed to ensure efficient collection and testing of groundwater samples.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater detection technology, specifically a groundwater pollution detection device. Background Technology
[0002] With rapid industrial development, groundwater has become polluted to varying degrees. Before groundwater treatment, it is necessary to drill and collect groundwater samples to test the degree of pollution. For example, in the groundwater pollution detection equipment disclosed in Chinese patent literature (application number: CN202421423169.3), the support plate moves up and down by two synchronous motors operating simultaneously. Even if there is a slight difference in the rotation speed between two synchronous motors of the same model, the support plate cannot move up and down stably during the operation of the synchronous motors, which affects the sampling process of the water sampling metal pipe. Moreover, the water sampling depth of the water sampling metal pipe depends entirely on the length of the hollow pipe and the moving distance of the support plate. If the distance exceeds the length of the hollow pipe and the moving distance of the support plate, groundwater sampling cannot be completed.
[0003] Therefore, we propose a groundwater pollution detection device. Utility Model Content
[0004] The purpose of this invention is to provide a groundwater pollution detection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a groundwater pollution detection device, comprising a base, a fixed frame, a lifting plate, a detector, and a storage box. The base is provided with a fixed frame and a guide rod. The fixed frame has mounting grooves on both sides, and threaded rods are installed in the mounting grooves. A first servo motor is located on the top left side of the fixed frame, and a second servo motor is located on the top of the lifting plate. Connecting plates are provided on both sides of the lifting plate. A rotating rod is located at the bottom of the lifting plate, and an extension rod is located at the bottom of the rotating rod. A sleeve is located at the bottom of the extension rod, and a sample collection tube is installed inside the sleeve. A drill bit is located at the bottom of the sleeve. A first bevel gear is located at the lower part of the threaded rod. A positioning block is located on the base, and a connecting shaft is located on the positioning block. Second bevel gears are located at both ends of the connecting shaft.
[0006] Furthermore, the top of the extension rod is provided with a T-shaped mounting groove, the bottom of the rotating rod is provided with a T-shaped mounting block that mates with the T-shaped mounting groove, the left side of the T-shaped mounting groove is provided with a threaded hole, the right side of the T-shaped mounting groove is provided with a second through hole, the middle of the T-shaped mounting block is provided with a first through hole, and a bolt is provided in the first through hole.
[0007] Furthermore, the connection method between the extension rod and the sleeve is the same as the connection method between the rotating rod and the extension rod.
[0008] Furthermore, the top end of the threaded rod passes through the top of the fixed frame and connects to the first servo motor, which is fixed to the top of the fixed frame.
[0009] Furthermore, the connecting plates on both sides of the lifting plate are installed into the mounting groove, the threaded rod passes through the connecting plate, and the connecting plate is provided with threaded holes that cooperate with the threaded rod.
[0010] Furthermore, the top of the rotating rod passes through the lifting plate and connects to the second servo motor, which is fixedly mounted on the lifting plate.
[0011] Furthermore, the guide rods are provided in two sets, both sets of guide rods passing through the lifting plate, and the guide rods are slidably connected to the lifting plate.
[0012] Furthermore, the positioning blocks are provided in two sets, and the two sets of positioning blocks are connected to the connecting shaft through bearings.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The first bevel gear and the second bevel gear cooperate to drive the connecting shaft to rotate. The second bevel gear at the other end of the connecting shaft rotates synchronously, which drives the first bevel gear at the lower part of the threaded rod on the right side of the fixed frame to rotate.

[0015] 2. Rotate the bolt to remove it. Disassemble the connection between the extension rod and the sleeve in the same way. Move the extension rod forward or backward to disassemble it. Then, reverse the first servo motor to raise the lifting plate. After the lifting plate has risen to a sufficient height, connect the bottom end of the extension rod to the sleeve first. Leave a distance between the top of the extension rod and the rotating rod. Install another extension rod section between the extension rod and the rotating rod to increase the drilling depth of this device. The number of extension rod sections installed can be flexibly adjusted according to the depth of the drilled sample to allow the device to drill groundwater samples at different depths.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6This utility model provides a technical solution: a groundwater pollution detection device, including a base 1, a fixed frame 2, a lifting plate 6, a detector 9, and a storage box 10. The base 1 is provided with the fixed frame 2 and a guide rod 3. The fixed frame 2 has mounting grooves 4 on both sides, and threaded rods 5 are installed in the mounting grooves 4. A first servo motor 7 is installed on the top left side of the fixed frame 2. A second servo motor 8 is installed on the top of the lifting plate 6. Connecting plates 61 are provided on both sides of the lifting plate 6. A rotating rod 11 is installed at the bottom of the lifting plate 6, and a [missing information - likely a device name or feature] is installed at the bottom of the rotating rod 11. An extension rod 12 has a sleeve 13 at its bottom, a sample collection tube 14 inside the sleeve 13, and a drill bit 15 at the bottom of the sleeve 13. A first bevel gear 16 is located at the lower part of the threaded rod 5. A positioning block 17 is located on the base 1, and a connecting shaft 18 is located on the positioning block 17. A second bevel gear 19 is located at both ends of the connecting shaft 18. When the first servo motor 7 is started, it drives the threaded rod 5 to rotate, and the first bevel gear 16 at the bottom of the threaded rod 5 rotates simultaneously. The first bevel gear 16 and the second bevel gear 19 rotate simultaneously. The bevel gear 19 engages with the connecting shaft 18, which rotates synchronously. The second bevel gear at the other end of the connecting shaft 18 rotates synchronously, causing the first bevel gear at the lower part of the threaded rod 5 on the right side of the fixed frame 2 to rotate synchronously. The threaded rods 5 on both sides of the fixed frame 2 rotate synchronously. The connecting plate 61 has threaded holes that engage with the threaded rods 5. The rotation of the threaded rods 5 causes the connecting plate 61 to move the lifting plate 6 downward. The synchronous rotation of the threaded rods 5 on both sides of the fixed frame 2 enhances the stability of the lifting plate 6. At the same time as the first servo motor 7 is started, the second servo motor 8 is started. The second servo motor 8 drives the rotating rod 11 to rotate. The rotating rod 11 drives the sleeve 13 to rotate through the extension rod 12, causing the drill bit at the bottom of the sleeve 13 to drill. The sample collection tube 14 inside the sleeve 13 is then inserted into the ground to collect groundwater samples. After sampling, the groundwater samples collected by the sample collection tube 14 are placed in the storage box 10, and the detector 10 tests the groundwater samples to determine the degree of groundwater pollution.
[0025] Reference embodiment: The top of the extension rod 12 is provided with a T-shaped mounting groove 20, and the bottom of the rotating rod 11 is provided with a T-shaped mounting block 25 that mates with the T-shaped mounting groove 20. A threaded hole 21 is provided on the left side of the T-shaped mounting groove 20, and a second through hole 23 is provided on the right side of the T-shaped mounting groove 20. A first through hole 22 is provided in the middle of the T-shaped mounting block 25, and a bolt 24 is installed in the first through hole 22. The connection method between the extension rod 12 and the sleeve 13 is the same as the connection method between the rotating rod 11 and the extension rod 12. When the height of the lifting plate 6 is insufficient for the sample collection tube 14 to obtain a groundwater sample, during the drilling process, before the connection between the rotating rod 12 and the sleeve 13 is about to penetrate deep into the ground, the drilling is stopped. A servo motor 7 rotates the bolt 24 to remove it. The connection between the extension rod 12 and the sleeve 13 is disassembled in the same way. The extension rod 12 is moved forward or backward to disassemble it. Then, the first servo motor 7 reverses to raise the lifting plate 6. After the lifting plate 6 rises to a sufficient height, the bottom end of the extension rod 12 is first connected to the sleeve 13. A distance is left between the top of the extension rod 12 and the rotating rod 11. Another extension rod 12 is installed between the extension rod 12 and the rotating rod 11 to increase the drilling depth of the device. The number of extension rod sections can be flexibly installed according to the depth of the drilled sample, so that the device can drill groundwater samples at different depths.
[0026] Reference embodiment: The top end of the threaded rod 5 passes through the top of the fixed frame 2 and is connected to the first servo motor 7. The first servo motor 7 is fixed to the top of the fixed frame 2. The connecting plates 61 on both sides of the lifting plate 6 are installed into the mounting groove 4. The threaded rod 5 passes through the connecting plate 61. The connecting plate 61 is provided with threaded holes that cooperate with the threaded rod 5. The first servo motor 7 drives the threaded rod 5 to rotate. When the threaded rod 5 rotates, the threaded holes on the connecting plate 61 cooperate with the threaded rod 5, causing the lifting plate 6 to move up and down.
[0027] Reference embodiment: The top of the rotating rod 11 passes through the lifting plate 6 and is connected to the second servo motor 8. The second servo motor 8 is fixedly installed on the lifting plate 6. The second servo motor 8 drives the rotating rod 11 to rotate. The rotating rod 11 drives the sleeve 13 to rotate through the extension rod 12, so that the drill bit set at the bottom of the sleeve 13 drills into the ground. The lower part of the sleeve 13 is provided with through grooves at the front and back to facilitate the collection of groundwater samples by the sample collection tube 14.
[0028] Reference embodiment: Two sets of guide rods 3 are provided, and both sets of guide rods 3 pass through the lifting plate 6. The guide rods 3 are slidably connected to the lifting plate 6. The guide rods 3 guide the up and down movement of the lifting plate 6, making the up and down movement of the lifting plate 6 more stable.
[0029] Reference embodiment: Two sets of positioning blocks 17 are provided. The two sets of positioning blocks 17 are connected to the connecting shaft 18 through bearings. The two sets of positioning blocks 17 provide stable support for the connecting shaft 18.
