[0047] Specifically: through the designed liquid distribution mechanism 5, when a treatment test is required, the test water in the water tank 2 is drawn by the pump body in the water tank 2 and injected into the liquid distribution mechanism 5, and the liquid distribution mechanism 5 can evenly distribute the water into the test box 4, wherein the test water can be prepared as polluted water with different degrees of pollution as needed. Each water tank 2 preferably controls a layer of test box 4, so that multiple water tanks 2 can be configured to be injected into test boxes 4 at different layers as needed. By simulating different treatment environments and test conditions in test boxes 4 at different layers, and by arranging multiple repeated test boxes 4 on each layer, it is beneficial to improve the accuracy of the test. By stacking multiple groups of test boxes 4, it is beneficial to reduce the occupied area of ​​​​the expanded detection environment, and in conjunction with the corresponding water tanks 2 and pumping equipment, it is convenient to carry out test management and adjustment, and improve the detection adaptability.

[0048] Furthermore, after the test water is injected into the liquid distribution frame 501 of the liquid distribution mechanism 5, the test water can flow through the liquid cavity in the liquid distribution frame 501 and then be sprayed out through the liquid delivery nozzle 503. The liquid delivery nozzles 503 symmetrically arranged on both sides can deliver and distribute liquid at the bottom or top layer of the test box 4, which is beneficial to improving the uniformity of liquid distribution through multiple groups of liquid delivery nozzles 503.

At the same time, valves are provided at the connection points of the pipelines to facilitate manual control of the operation of the water circulation system as needed.

[0050] In another embodiment, in order to achieve water circulation, each group of test boxes 4 preferably circulates the water to the corresponding water tank 2 through a pipe, and then circulates the water through a water pump.

[0051] In another preferred embodiment, if corresponding ecological plants are planted on the top of the test box 4 through a floating bed or other structure, the liquid delivery nozzle 503 located on the top can spray liquid to irrigate the plants; it is particularly suitable for the desalination process in saline-alkali water purification, such as when evaporation causes salt to accumulate into a salt layer, and the plants are subjected to strong salt stress. The salt can be dissolved by spraying water to reduce the salt content in the surface layer and the root zone of the plants.

[0052] At the same time, when distributing liquid, the top driving part 514 can drive the driving rod 510 and the supporting cams 509 on both sides to rotate, and the rotation of the supporting cam 509 can squeeze the push rod 508 at the corresponding position, and the movement of the push rod 508 can drive the moving rod 507 to push the flap 506 and the driving ring 504 to rotate, and the rotation of the driving ring 504 can drive the nozzle at the corresponding position to adjust the angle, and when the longer end of the cam is separated from the push rod 508, the first spring 513 can use its own elastic force to drive the push rod 508 to reset, and the reset push rod 508 can pull the moving rod 507 and the liquid feeding nozzle 503 to reset, so as to realize the driving of the reciprocating angle of the nozzle, which is beneficial to enhance the feeding uniformity of the water body through the frequency vibration of the nozzle, and improve the full contact and mixing effect of the water flow drawn from the water tank 2 and the water body in the test box 4 in the subsequent test;

[0053] Furthermore, through the designed sliding rod 512, the movement of the sliding rod 512 in the fixing sleeve 511 is more stable, and the axial bounce of the moving rod 507 and the driving ring 504 can be avoided;

[0054] At the same time, through the designed liquid inlet valve part 502, the opening and closing of the cavity corresponding to the liquid distribution mechanism 5 at the bottom of the connecting pipeline 9 can be adjusted when pumping liquid, which is convenient for adjusting the liquid addition frequency and pipeline connection control in different test boxes 4.

Through the cooperation of the rotating ball 603 and the traction rope 602, the relative deviation distance of the connecting pipe 9 between the flexible sleeves 601 on both sides can be adjusted, which is beneficial to improve the connectivity adaptation of the liquid distribution frame 501 after the height adjustment through the setting of the flexible traction rope 602. Among them, the connecting pipe 9 located between the flexible sleeves 601 on both sides should be a flexible pipe to adapt to the flexible expansion adjustment of the connecting pipe 9 and improve adaptability.

[0057] See also Figure 8-Figure 10A limiting groove 702 is provided on the top of the chassis 701, and a card block is connected to the bottom of the test box 4, which is clamped in the limiting groove 702. The limiting blocks 703 are slidably connected on both sides of the inner cavity of the limiting groove 702. The limiting blocks 703 on both sides move toward each other.

[0058] A socket 710 is connected to the position of the limit cam 709 on one side of the bottom of the chassis 701, and the connection seat 708 is supported by the limit cam 709 in the socket 710. Both ends of the two sides of the chassis 701 are connected with sliders 711, and the sliders 711 are slidably connected in the sliding grooves opened in the inner cavity of the frame 1.

[0059] Specifically: through the designed limiting mechanism 7, when it is necessary to switch the test environment, the limiting cam 709 can be twisted to separate from the corresponding position of the holder 710. At this time, the shorter end of the limiting cam 709 can contact with the connecting seat 708 on one side, thereby releasing the restriction on the connecting seat 708. At this time, the connecting seat 708 can drive the movable plate 706 at the corresponding position to move through multiple fixed rods 707 on one side. The movable plate 706 can pull the limiting telescopic rod 704 and the limiting block 703 to move. At this time, the limiting block 703 can be separated from the bottom block of the test box 4, and the test box 4 can be pulled out from the top of the chassis 701, which is conducive to the independent disassembly of the test box 4. The modularly assembled test box 4 can facilitate the combination and adjustment of the test box 4 for different test simulation conditions.

[0060] And when the limit cam 709 is inserted into the holder 710, it can drive the connecting seat 708 and the limit block 703 to abut and limit the side of the block, wherein the block can be provided with an arc-shaped groove body that engages with the limit block 703 as needed to improve the axial limiting ability, which is beneficial to improving the stability of the test box 4 installed on the top of the chassis 701.

[0061] Working principle: When in use, when a treatment test is required, the water in the water tank 2 is pumped into the liquid distribution mechanism 5 through the pump body in the water tank 2, and the liquid distribution mechanism 5 evenly distributes the water into the test box 4, wherein the water can be prepared with polluted water of different pollution degrees as needed, and multiple water tanks 2 are configured to be injected into different layers of the test boxes 4 as needed, so as to simulate different treatment environments and test conditions in the test boxes 4 at different layers;

[0062] The top driving part 514 drives the driving rod 510 and the supporting cams 509 on both sides to rotate, and the supporting cams 509 rotate to squeeze the push rod 508 at the corresponding position, and the push rod 508 moves to drive the moving rod 507 to push the flap 506 and the driving ring 504 to rotate, and the driving ring 504 rotates to drive the nozzle at the corresponding position to adjust the angle, and when the longer end of the cam is separated from the push rod 508, the first spring 513 uses its own elastic force to drive the push rod 508 to reset, and the reset push rod 508 pulls the moving rod 507 and the liquid delivery nozzle 503 to reset;

When the flexible sleeve 601 moves, it pulls the rotating ball 603 and the traction rope 602 on one side. The relative deflection distance of the connecting pipe 9 between the flexible sleeves 601 on both sides is adjusted through the cooperation of the rotating ball 603 and the traction rope 602, which is conducive to improving the connection adaptation of the liquid distribution frame 501 after the height adjustment through the setting of the flexible traction rope 602;

[0064] By twisting the limit cam 709, it is separated from the holder 710 at the corresponding position. At this time, the shorter end of the limit cam 709 contacts the connecting seat 708 on one side, thereby releasing the restriction on the connecting seat 708. At this time, the connecting seat 708 drives the movable plate 706 at the corresponding position to move through multiple fixed rods 707 on one side. The movable plate 706 pulls the limit telescopic rod 704 and the limit block 703 to move. At this time, the limit block 703 is separated from the bottom block of the test box 4, and the test box 4 is pulled out from the top of the chassis 701.
