[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] See also Figures 1 to 8 As shown, a stratified sampling device for wastewater testing includes a mounting pipe 1, a plurality of slideways 2 fixedly connected to the mounting pipe 1, a slider 3 slidably connected to the slideway 2, a water intake tank 4 fixedly connected to one side of the slider 3, a float 6 fixedly connected to the bottom of the water intake tank 4, and a water supply and drainage mechanism provided on the outer surface of the mounting pipe 1 for supplying and draining water into and out of the mounting pipe 1;

[0033] The outer surface of the mounting tube 1 is provided with a plurality of mounting threaded holes 5, the inner threads of the mounting threaded holes 5 are connected to a stratified water inlet mechanism connected to the water intake tank 4, and the stratified water inlet mechanism is used to supply water to the water intake tank 4;

[0034] A supporting mechanism is provided on the outer surface of the mounting pipe 1 , and the supporting mechanism is used to support and fix the mounting pipe 1 .

[0035] The internal thread of the mounting threaded hole 5 is connected with a sealing block, and a rotating column is fixedly connected to the sealing block.

[0036] According to the required stratified water extraction process, the corresponding stratified water inlet mechanism is installed in the installation threaded hole 5 according to the depth of each water extraction layer, and then the other installation threaded holes 5 are turned into the sealing block to seal the installation threaded hole 5, and then the installation pipe 1 is inserted into the wastewater pool for detection. After the wastewater pool is still, stratified water is extracted. At this time, the stratified water inlet mechanism of the corresponding stratified position is started, and then the slider 3 on the water extraction tank 4 is placed into the slide 2. The water extraction tank 4 enters the corresponding stratified water inlet mechanism position along the slide 2. Then the stratified water inlet mechanism is opened, and the water of the corresponding layer is passed into the water extraction tank 4. After the water extraction is completed, the water in the installation pipe 1 is then emptied through the water supply and drainage mechanism. Water is supplied. At this time, the buoyancy of the water in the installation pipe 1 drives the float 6 at the bottom of the water intake tank 4 to move upward. At the same time, with the cooperation of the stratified water inlet mechanism, the float 6 drives the water intake tank 4 to move upward, so that it moves to the top of the installation pipe 1, and then the water intake tank 4 is taken out. When sampling the next layer of wastewater, the water in the installation pipe 1 is discharged through the water supply and drainage mechanism, and then the new water intake tank 4 is placed in the installation pipe 1. The above operation is repeated to take water, thereby realizing static water extraction of different wastewater layers in the wastewater pool, effectively avoiding the flow of the water intake layer during the water intake process, causing changes in the sewage in the water intake layer, and ensuring the water intake quality of each layer.

[0037] Example 2

[0038] Based on Example 1, please refer to Figures 3 to 8 As shown, the stratified water inlet mechanism includes a mounting ring 11 threadedly connected to the mounting threaded hole 5, a water inlet pipe 12 is slidably connected to the mounting ring 11, a transmission ring 13 is fixedly connected to the outer surface of the water inlet pipe 12, a first spring 14 fixedly connected to the transmission ring 13 is fixedly sleeved on the outer surface of the water inlet pipe 12, an electromagnet block 15 is fixedly connected to one side of the mounting ring 11, a permanent magnet block 16 is fixedly connected to the outer surface of the water inlet pipe 12, and a support frame 17 is fixedly connected to the outer surface of the water inlet pipe 12, which is slidably connected to the bottom of the water intake tank 4;

[0039] An opening and closing mechanism connected to the water intake box 4 is provided in the water inlet pipe 12 , and the opening and closing mechanism is used to open and close the water inlet pipe 12 .

[0040] The opening and closing mechanism includes a connecting plate 21 fixedly connected to the water inlet pipe 12, a transmission column 22 is slidably connected to the connecting plate 21, the outer surface of the transmission column 22 is fixedly sleeved with a second spring 23 fixedly connected to the connecting plate 21, one end of the transmission column 22 is fixedly connected to a sealing plate 24, a sealing ring 25 is fixedly connected in the water inlet pipe 12, a rubber sealing gasket 26 is fixedly connected to the sealing ring 25, a top column 27 is fixedly connected in the water tank 4, a lifting handle is fixedly connected in the water tank 4, and the outer surface of the mounting ring 11 is fixedly connected to a rotating column.

[0041] The water supply and drainage mechanism includes a water inlet pump 31 fixedly connected to the mounting pipe 1, the water inlet pump 31 is fixedly connected to the mounting pipe 1 through a pipe, a water suction pipe 32 is fixedly connected to one side of the water inlet pump 31, and a drainage pump 33 fixedly connected to the mounting pipe 1 is arranged above the water inlet pump 31, the drainage pump 33 is connected to the mounting pipe 1 through a pipe, and the output end of the drainage pump 33 is fixedly connected to the drainage pipe 34, and a one-way valve 35 is provided on both the suction pipe 32 and the drainage pipe 34. Water is pumped into the mounting pipe 1 through the water inlet pump 31 and the suction pipe 32. The one-way valve on the suction pipe 32 controls the water to enter the mounting pipe 1 in one direction only from the suction pipe 32, and the water in the mounting pipe 1 is discharged through the drainage pump 33 and the drainage pipe 34. At the same time, the water in the mounting pipe 1 can only flow outward through the one-way valve 35 on the drainage pipe 34.

[0042] When water is taken, first, the electromagnet block 15 on the stratified water inlet mechanism mounting ring 11 corresponding to the water intake layer is started. The electromagnet block 15 generates the same magnetic pole as the permanent magnet block 16. At this time, a certain repulsive force is generated on the permanent magnet block 16, driving the permanent magnet block 16 and the water inlet pipe 12 to move, and the water inlet pipe 12 drives the support frame 17 to move a distance. Then, the slider 3 on the water intake tank 4 is placed in the slide 2 in the mounting tube 1. Then, the water intake tank 4 moves downward under the action of gravity. Then, the bottom of the water intake tank 4 is supported by the support frame 17, so that the water intake tank 4 moves to the corresponding water intake stratification position. Then, the current of the electromagnet block 15 is increased, and the electromagnet block 15 generates a greater repulsive force, which drives the permanent magnet block 16 and the water inlet pipe 12 to move, so that the water inlet pipe 12 enters the water inlet groove on the water intake tank 4. At this time, the first spring 14 on the water inlet pipe 12 is compressed. At the same time, during the movement, the top column 27 in the water intake tank 4 begins to push open the sealing plate 24 on the water inlet pipe 12. At this time, the sealing plate 24 moves, the transmission column 22 and the second spring 23 are compressed, and the sealing plate 24 disengages from the rubber sealing gasket 26 on the sealing ring 25. At this time, the water inlet pipe 12 is opened, and water enters the water intake box 4 from the water inlet pipe 12 to realize water intake of the water intake box 4. When the water intake is completed, the water supply and drainage mechanism supplies water to the installation pipe 1 to control the water inflow in the installation pipe 1. At the same time, the electromagnet block 15 is fed with reverse current to start attracting the permanent magnet block 16, and the permanent magnet block 16 drives the water inlet pipe 12 to move, so that the water inlet pipe 12 is moved out of the water intake trough on the water intake box 4. Subsequently, as the water inflow in the installation pipe 1 generates buoyancy, the buoyancy drives the water intake box 4 to move upward, so that the water intake box 4 is moved out of the installation pipe 1. After the next water intake, the water in the installation pipe 1 is discharged, and then the above operation is repeated, thereby realizing static water intake of different layers of wastewater, effectively avoiding the flow of the water intake layer during the water intake process, causing the sewage in the water intake layer to change, and ensuring the water intake quality of each layer.

[0043] Example 3

[0044] Based on Example 1, please refer to Figure 1 As shown, the support mechanism includes a plurality of connection frames 41 fixedly connected to the mounting pipe 1 , support columns 42 are rotatably connected inside the connection frames 41 , and fixing bolts 43 threadedly connected to the support columns 42 are threadedly connected to the connection frames 41 .

[0045] A tapered column 44 is fixedly connected to the bottom of the mounting tube 1 .

[0046] By rotating and unfolding the support column 42 in the connecting frame 41, and then fixing the support column 42 with the fixing bolt 43, the installation pipe 1 is inserted into the wastewater tank. At the same time, the tapered column 44 is used to facilitate the insertion of the installation pipe 1. At the same time, the support column 42 supports the installation pipe 1, thereby improving the stability of the installation of the installation pipe 1 in the wastewater tank.

[0047] Working principle: When in use, when taking water, first, the electromagnet block 15 on the stratified water inlet mechanism mounting ring 11 corresponding to the water intake layer is started, and the electromagnet block 15 generates the same magnetic pole as the permanent magnet block 16. At this time, a certain repulsive force is generated on the permanent magnet block 16, driving the permanent magnet block 16 and the water inlet pipe 12 to move, and the water inlet pipe 12 drives the support frame 17 to move a distance, and then the slider 3 on the water intake tank 4 is placed in the slide 2 in the mounting tube 1, and then the water intake tank 4 moves downward under the action of gravity, and then the bottom of the water intake tank 4 is supported by the support frame 17, so that the water intake tank 4 moves to the corresponding water intake stratification position, and then the current of the electromagnet block 15 is increased, and the electromagnet block 15 generates a greater repulsive force, which drives the permanent magnet block 16 and the water inlet pipe 12 to move, so that the water inlet pipe 12 enters the water inlet groove on the water intake tank 4, and the first spring 14 on the water inlet pipe 12 is compressed. At the same time, during the movement, the top column 27 in the water intake tank 4 begins to push open the water inlet pipe 12. The sealing plate 24 moves, the transmission column 22 and the second spring 23 are compressed, and the sealing plate 24 is separated from the rubber sealing gasket 26 on the sealing ring 25. At this time, the water inlet pipe 12 is opened, and water enters the water tank 4 from the water inlet pipe 12 to realize water extraction from the water tank 4. When the water extraction is completed, the water supply and drainage mechanism supplies water to the installation pipe 1 to control the water inflow into the installation pipe 1. At the same time, the electromagnet block 15 is connected to the reverse current to start adsorbing the permanent magnet block 16. The permanent magnet block 16 carries The movable water inlet pipe 12 moves, so that the water inlet pipe 12 is removed from the water intake trough on the water intake box 4. Then, as the water inflows into the installation pipe 1, buoyancy is generated, and the buoyancy drives the water intake box 4 to move upward, so that the water intake box 4 is removed from the installation pipe 1. After the next water intake, the water in the installation pipe 1 is discharged, and then the above operation is repeated, thereby realizing static water intake of wastewater in different layers, effectively avoiding the flow of the water intake layer during the water intake process, causing the sewage in the water intake layer to change, and ensuring the water intake quality of each layer.

[0048] By rotating and unfolding the support column 42 in the connecting frame 41, and then fixing the support column 42 with the fixing bolt 43, the installation pipe 1 is inserted into the wastewater tank. At the same time, the tapered column 44 is used to facilitate the insertion of the installation pipe 1. At the same time, the support column 42 supports the installation pipe 1, thereby improving the stability of the installation of the installation pipe 1 in the wastewater tank.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
