[0002] A stratified sampler is a specialized device for collecting liquid samples, playing a vital role in wastewater research, liquid stratification sampling, and water sampling. In water quality testing, it can collect water samples and analyze the stratification of different components, providing data support for wastewater treatment process optimization and treatment. In liquid stratification sampling, it can perform stratified sampling of various liquids, helping to study the distribution patterns and characteristics of liquid layers. In water sampling, by collecting water samples at different depths, it can detect changes in water quality, thereby assessing water quality and ensuring the rational use and protection of water resources.

[0003] Currently, most sampling equipment uses bolts to fix the sampling containers, which makes it very inconvenient to disassemble, inspect, maintain, or replace the sampling containers. This not only requires the corresponding tools but also wastes time, increasing time costs and manpower burden. Therefore, to address the above problems, a stratified sampler for water quality monitoring is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problem that the sampling box of the stratified sampler used for water quality testing is not easy to disassemble, this utility model proposes a stratified sampler for water quality monitoring.

Two first return springs are fixedly connected to one side of the pressing block, and one end of each first return spring is fixedly connected to the inner wall of the mounting box. A moving block is fixedly connected to the top of the pressing block, and the top of the moving block extends through to the outside of the mounting box. A locking block is fixedly connected to one side of the moving block, and one side of the locking block extends into the inner cavity of the mounting hole.

[0006] Preferably, the top surface of the sampling port is in contact with a sampling cover, the top of the sampling cover is fixedly connected to a moving rod, the top of the moving rod is fixedly connected to a connecting plate, two connecting rods are provided on one side of the mounting plate, the two sides of the connecting plate are respectively fixedly connected to the two connecting rods, the top of the connecting rods extends through to the top of the top plate, and a handle is fixedly connected between the two connecting rods.

[0007] Preferably, two limiting plates are fixedly connected to one side of the connecting plate, and a limiting rod is movably connected to the inner cavity of the limiting plate.

[0012] The advantages of this utility model are: This invention features an installation assembly. A rotating wheel drives a rotating rod and a cam to rotate, causing the cam to compress and move the compression block. The compression block then moves a moving block, which in turn moves a locking block out of the mounting hole, releasing the mounting block from installation. When installation is required, the wheel can be reversed. In this case, the compression block is not under force, and a first return spring moves the compression block, which in turn moves the moving block. The moving block then moves the locking block into the mounting hole, completing the installation. To disassemble, simply reverse the wheel to remove the locking block from the mounting hole, releasing the restriction on the mounting block. The sampling box can then be disassembled. This greatly facilitates subsequent disassembly, maintenance, and replacement, significantly reducing labor and time costs. Attached Figure Description

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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a stratified sampler for water quality monitoring. (Refer to...) Figures 1-4 A stratified sampler for water quality monitoring includes a mounting plate 1, a top plate 2 fixedly connected to the top of the mounting plate 1, two sampling boxes 3 in contact with the surface of the mounting plate 1, a stabilizing box 4 fitted onto the surface of the sampling box 3, one side of the stabilizing box 4 fixedly connected to the surface of the mounting plate 1, a sampling port 5 opened at the top of the sampling box 3, a mounting block 6 fixedly connected to one side of the sampling box 3, a mounting hole 7 opened on the surface of the mounting block 6, one side of the mounting block 6 extending to the outside of the mounting plate 1, and a mounting assembly 8 provided on the surface of the mounting block 6. The mounting assembly 8 includes a mounting box 801. One side of the mounting box 801 is fixedly connected to the surface of the mounting plate 1. A rotating wheel 802 is provided on one side of the mounting box 801. A rotating rod 803 is fixedly connected to one side of the rotating wheel 802. One end of the rotating rod 803 passes through the inner cavity of the mounting box 801 and is fixedly fitted with a cam 804. Both sides of the cam 804 are in contact with pressing blocks 805. Two first return springs 806 are fixedly connected to one side of the pressing block 805. One end of each first return spring 806 is fixedly connected to the inner wall of the mounting box 801. A moving block 807 is fixedly connected to the top of the pressing block 805. The top of the moving block 807 extends through to the outside of the mounting box 801. A locking block 808 is fixedly connected to one side of the moving block 807. One side of the locking block 808 extends into the inner cavity of the mounting hole 7. By setting the mounting assembly... 8. The rotating wheel 802 drives the rotating rod 803 and cam 804 to rotate. The cam 804 squeezes the squeezing block 805 to move. The squeezing block 805 drives the moving block 807 to move. The moving block 807 drives the locking block 808 to move out of the mounting hole 7, thus releasing the mounting block 6 from installation. When installation is required, the rotating wheel 802 can be reversed. At this time, the squeezing block 805 is not under force. The first return spring 806 drives the squeezing block 805 to move. The squeezing block 805 drives the moving block 807 to move. The moving block 807 drives the locking block 808 into the mounting hole 7. At this time, the installation is completed. When disassembly is required, simply reverse the rotating wheel 802 to move the locking block 808 out of the mounting hole 7, releasing the restriction on the mounting block 6. Then the sampling box 3 can be disassembled. This is very convenient for later disassembly, maintenance and replacement, greatly reducing labor and time costs.

[0018] Reference Figure 1 and Figure 2 The top surface of the sampling port 5 is in contact with a sampling cover 9. A moving rod 10 is fixedly connected to the top of the sampling cover 9. A connecting plate 11 is fixedly connected to the top of the moving rod 10. Two connecting rods 12 are provided on one side of the mounting plate 1. The two sides of the connecting plate 11 are fixedly connected to the two connecting rods 12 respectively. The top of the connecting rod 12 extends through to the top of the top plate 2. A handle 13 is fixedly connected between the two connecting rods 12. By setting the sampling cover 9, the sampling port 5 can be sealed and protected. By setting the moving rod 10 and the connecting rod 12, the closing of the sampling cover 9 can be controlled. By setting the handle 13, it is easier for the user to operate. Reference Figure 1 and Figure 2 Two limiting plates 14 are fixedly connected to one side of the connecting plate 11. A limiting rod 15 is movably connected to the inner cavity of the limiting plate 14. The bottom of the limiting rod 15 is fixedly connected to the surface of the stabilizing box 4. A limiting piece 16 is fixedly connected to the top of the limiting rod 15. By setting the limiting rod 15, the stability of the limiting plate 14 when moving can be improved. By setting the limiting piece 16, the moving distance of the limiting plate 14 can be limited. Reference Figure 1 and Figure 2 A second reset spring 17 is sleeved on the surface of the limiting rod 15. The two ends of the second reset spring 17 are fixedly connected to the bottom of the limiting piece 16 and the top of the limiting plate 14, respectively. By setting the second reset spring 17, the sampling cover 9 can be easily reset downward. Reference Figure 1 The surface of the sampling box 3 is fixedly connected to a water outlet pipe 18, and a sealing cap 19 is fitted on the surface of the water outlet pipe 18. By setting the water outlet pipe 18, it is convenient to collect the samples after sampling. By setting the sealing cap 19, it is possible to effectively prevent impurities from entering through the water outlet pipe 18 during sampling. Reference Figure 3 and Figure 4 The surface of the rotating rod 803 is rotatably connected to the mounting box 801 via a bearing. The shape of the locking block 808 is trapezoidal. By setting the bearing, the installation and use of the rotating rod 803 can be facilitated, and the stability of the rotating rod 803 during rotation can be improved. Reference Figure 1 and Figure 3 A handle 20 is fixedly connected to the top of the top plate 2, and a sealing ring 21 is fixedly fitted on the surface of the sampling port 5. The handle 20 facilitates the handling by personnel during use, and the sealing ring 21 improves the sealing performance of the sampling box 3, effectively isolating other impurities. Working principle: When sampling box 3 needs to be installed, it should first be aligned with the stabilizing box 4 on the mounting plate 1. After alignment, sampling box 3 and mounting block 6 are pushed in. At this time, mounting block 6 presses against locking block 808. Locking block 808 drives moving block 807 to move. Moving block 807 drives pressing block 805 to press against the first return spring 806. When sampling box 3 is in contact with mounting plate 1, locking block 808 corresponds to mounting hole 7. Second return spring 17 drives pressing block 805 to move in the opposite direction, pressing... Block 805 moves movable block 807, which in turn moves locking block 808 into mounting hole 7, completing the installation. When manual replacement is required, rotating wheel 802 rotates, causing rotating rod 803 to rotate. Rotating rod 803 then rotates cam 804, which in turn presses and compresses pressing block 805. Pressed, pressing block 805 begins to move, moving movable block 807, which in turn moves locking block 808 completely out of mounting hole 7. At this point, the restriction on the installation block 6 is complete, and the sampling box 3 can be removed. During sampling, the user holds handle 20 and places the sampler into the target water area. With the other hand, they pull handle 13. Handle 13 moves connecting rod 12 upwards, which in turn moves connecting plate 11 upwards. Connecting plate 11 then moves limiting plate 14 upwards, pressing the second return spring 17. Simultaneously, connecting plate 11 moves moving rod 10 upwards, which in turn moves sampling cover 9 upwards to release the restriction on sampling. When port 5 is closed, water flows into sampling box 3. After collecting enough water, release handle 13. At this time, the second reset spring 17 resets. The second reset spring 17 drives the limiting plate 14 to reset downward. The limiting plate 14 drives the connecting plate 11 to move downward. The connecting plate 11 drives the moving rod 10 to move downward. The moving rod 10 drives the sampling cover 9 to block the sampling port 5 downward, stopping sampling. After sampling is completed, take the sampler out of the water and open the sealing cover 19 of the water outlet pipe 18 to drain the sampled water.
