[0047] In this embodiment, a second threaded rod 11 is rotatably connected in the limit frame 9, a volute spring 10 is welded and fixed in the limit frame 9, the inner end of the volute spring 10 is welded and fixed on the second threaded rod 11, a coil 12 is welded and fixed on the second threaded rod 11, a traction rope 13 is wound around the coil 12, and the top of the traction rope 13 is fixedly connected to the bottom end surface of the top plate 4, an air storage frame 16 is welded and fixed in the bottom plate 1, a rubber suction cup 17 is connected to the air storage frame 16, a threaded sleeve 14 is threadedly connected to the second threaded rod 11, a second rubber piston 15 is fixedly connected to the threaded sleeve 14, and the second rubber The piston 15 is slidably connected in the air storage frame 16, and the air storage frame 16 is symmetrically distributed on both sides of the bottom plate 1.

[0048] It should be noted that the present invention is an on-site analysis device for sewage. First, the staff can drive the hydraulic rod 3 on the fixed plate 2. At this time, the hydraulic rod 3 can push the top plate 4 to move upward, and the top plate 4 can drive the rubber frame 7 to move out of the device housing 6. Then the staff can place the various detection cylinders 819 to be used in the various positioning grooves 805 on the second support plate 824, and place the entire device on the workbench. During the upward movement of the top plate 4, the second threaded rod 11 can be driven to rotate automatically through the coil 12. Under the rotation of the second threaded rod 11, the volute spring 10 in the limit frame 9 can be compressed. At the same time, the second rubber piston 15 can be driven to move toward the rubber suction cup 17 through the threaded sleeve rod 14, and air can be pushed out of the rubber suction cup 17.

[0049] After each detection cylinder 819 is placed stably, the hydraulic rod 3 can be driven to drive the top plate 4 to move downward. At this time, under the cooperation of the rubber frame 7 and the device housing 6, the entire device can be protected. At the same time, the top plate 4 can drive the top end of the traction rope 13 to move downward. Therefore, under the elastic action of the spiral spring 10 inside the limit frame 9, the second threaded rod 11 can be driven to automatically rotate in the opposite direction. The threaded sleeve rod 14 connected by a thread can drive the second rubber piston 15 to automatically move in the air storage frame 16 and suck the air in each rubber suction cup 17. The internal negative pressure of each rubber suction cup 17 can be used to automatically and stably adsorb and fix the entire device on the work surface, thereby ensuring the stability of the subsequent working state of the entire device.

[0050] The movement of the top plate 4 drives the sample dividing cylinder 520 to press each detection cylinder 819 downward. Under the downward pressure of the detection cylinder 819, the first rubber piston 817 on the connecting spring 816 is pushed downward in the air storage cylinder 815. At this time, under the action of air pressure, the air at the bottom of the air storage cylinder 815 can be transported to the rubber airbag 806 through the air guide tube 818 for automatic inflation, thereby automatically clamping and positioning the detection cylinder 819. At this time, the detection cylinder 819 is located directly below the third guide tube 522, which is convenient for subsequent sample dividing and unloading.

[0051] The staff can then pull the clamping rod 508 on the connecting plate 506 and move it out of the clamping groove 504 on the treatment cylinder 501 to complete the disassembly and separation between the connecting frame 505 and the treatment cylinder 501. At this time, the filter cylinder 502 can be taken out and placed by grabbing the fixing rod 503, ensuring the convenience of its subsequent cleaning work; the staff can then stably transport the sewage sample into the treatment cylinder 501. At this time, it is only necessary to repeat the above operation, place the connecting frame 505 on the treatment cylinder 501, and then release the clamping rod 508. The clamping rod 508 can automatically snap into the clamping groove 504 on the treatment cylinder 501 under the elastic action of the return spring 507, completing the clamping and fixing between the connecting frame 505 and the treatment cylinder 501 to prevent the sewage sample from leaking;

[0052] The first servo motor 509 on the driving connection frame 505 is driven. The first servo motor 509 can drive the sealing plate 510 to rotate through the output shaft, and then drive the circular gear 512 on the reciprocating screw rod 511 to perform circular motion. At the same time, under the meshing drive action of the circular gear 512 and the internal gear 513, the reciprocating screw rods 511 on both sides can be driven to automatically rotate during the revolution, and then the connecting ring 515 can be driven to automatically and stably reciprocate up and down during the rotation process through the threaded connecting block 514, thereby driving the first mixing plates 516 and the second mixing plates 517 on the connecting ring 515 to automatically and stably reciprocate up and down during the rotation process, thereby achieving all-round and uniform stirring of the sewage sample, ensuring that various substances in the sample are evenly distributed, so that it can reflect the characteristics and pollution conditions of the overall sewage, and avoid uneven sampling affecting the accuracy of subsequent detection and analysis results;

[0053] The sample separation cylinder 520 can be divided into four independent areas by the partition plate 521. The staff only needs to open the solenoid valve on the first guide tube 518, and the sewage sample can be filtered by the filter cylinder 502 and then transported to the corresponding independent areas through the four second guide tubes 519. The four independent areas can then be automatically transported to the corresponding detection cylinder 819 through the corresponding third guide tubes 522, automatically completing the uniform sampling of the sewage sample. Subsequently, the hydraulic rod 3 drives the top plate 4 to move upward. Since the traction rope 13 is in a loose state when the top plate 4 moves downward to the lowest end, it is not necessary to straighten the traction rope 13 when the top plate 4 moves upward, which will not adversely affect the working state of the rubber suction cup 17.

[0054] After the top plate 4 drives the sample dividing cylinder 520 to move upward and separate from the detection cylinder 819, the second servo motor 801 can drive the first threaded rod 802 to rotate stably, and the threaded slider 803 can drive the positioning cylinder 804 to move toward the detection head 822 until the detection cylinder 819 on the far right moves to just below the detection head 822. At this time, the hydraulic rod 3 drives the top plate 4 and the connecting plate 823 to drive the detection head 822 to move downward synchronously. At this time, the connecting plate 823 can also press the detection cylinder 819 to position it, and the detection head 822 can be inserted into the sewage sample in the detection cylinder 819. In combination with the water quality analyzer 820, on-site detection and analysis of the sewage can be performed.

[0055] After the analysis of the sewage sample in the first detection cylinder 819 is completed, the detection head 822 moves up and drives the drive motor 807. At this time, under the driving action of the drive motor 807, the limit plate 809 and the guide rod 810 on the turntable 808 can be driven to rotate synchronously. The guide rod 810 moves into the guide groove 813 on the guide plate 812 and can move the guide plate 812 to rotate stably. Under the continuous movement of the guide rod 810, the guide plate 812 can be moved intermittently through the guide groove 813, and each time it rotates 90°, the guide plate 812 rotates intermittently. When the guide plate 812 stops rotating, the guide plate 812 can be limited by the fit between the limit plate 809 and the guide plate 812, thereby ensuring the stability of the intermittent rotation state of the guide plate 812. The intermittent rotation of the guide plate 812 can drive the first support plate 814 and the second support plate 824 to move synchronously through the rotating shaft 811, thereby driving each detection cylinder 819 to automatically and stably switch positions. Combined with the upward and downward movement of the detection head 822, the sewage samples in each detection cylinder 819 can be automatically and efficiently tested and analyzed in batches.

[0056] After the inspection work is completed, the hydraulic rod 3 can be used to push the top plate 4 upward, and the top plate 4 can drive the rubber frame 7 to move out of the device housing 6. Then the staff can take out and clean the various inspection cylinders 819 that need to be used for subsequent reuse.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
