It can detect a variety of water quality indicators, such as COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals (copper, chromium, zinc, etc.), disinfectants (residual chlorine, chlorine dioxide, etc.), and conventional water quality parameters (turbidity, color, dissolved oxygen, etc.); an intelligent operating system is set in the operating table 3, and it also has a large-capacity storage capacity, supporting the export of test data and uploading to the cloud platform; a high-definition touch screen is set on the observation table 4, and the test results can be observed in real time through the high-definition touch screen; The specific operation of the sewage continuous detection equipment is as follows: first, the collected multiple sewage samples are transferred to the test tube 9 through a pipette, and then the detection solution is dripped into the test tube 9, and then the test tube 9 is placed in the test tube seat 11 on the No. 1 ring body 10, and then the No. 1 ring body 10 is moved to transfer all the test tubes 9 to the rotating groove 7. The No. 1 ring body 10 can perform circular motion in the rotating groove 7. When a certain test tube 9 is rotated to the position relative to the water quality detector probe 6, the rotation of the No. 1 ring body 10 is stopped, and then the water quality detector probe 6 starts to detect the sewage in the test tube 9. After the detection is completed, the No. 1 ring body 10 continues to be rotated, and the next test tube 9 is rotated to the position relative to the water quality detector probe 6. , and perform sewage detection, and so on, the subsequent test tubes 9 are all carried out according to the above steps to realize the continuous detection operation of sewage collection samples, and the No. 1 ring body 10 and the rotating groove 7 are detachably connected, that is, the No. 1 ring body 10 can be removed, and multiple No. 1 ring bodies 10 are set.

The sewage samples can be tested continuously in batches. Compared with the existing loading, testing and unloading of each test tube 9 one by one, the sewage connection detection equipment 1 set in this embodiment has higher detection efficiency.

A No. 1 ring body 10 is installed on the outer gear ring 12. Specifically, a positioning pin 16 provided on the lower end face of the No. 1 ring body 10 is embedded in a positioning groove 15 provided on the upper end face of the outer gear ring 12, so that the No. 1 ring body can rotate synchronously with the outer gear ring 12.

At this time, the No. 2 ring body 22 is connected to multiple test tube holders 11 as a whole, and then the No. 1 ring body 10 and the No. 2 ring body 22 are grasped and squeezed against each other on the test tube holder 11, and then the multiple test tubes 9 are shaken as a whole. , the sewage sample and the detection agent are evenly mixed, and the shaking operation can be concentrated on multiple test tubes 9 to improve efficiency. At the same time, after the No. 1 ring body 10 is placed in the rotating groove 7, the No. 2 ring body 22 is also located in the rotating groove 7, and then the servo motor is driven. The servo motor drives the outer gear ring 12 to rotate alternately clockwise and counterclockwise, and can also drive multiple test tubes 9 to swing at the same time to mix the sewage sample and the detection agent in the test tube 9. After the mixing is completed, the servo motor drives the outer gear ring 12 to rotate intermittently clockwise or counterclockwise to detect the sewage samples in the test tube 9 one by one.

The upper and lower material racks 8, and the positioning pins 16 of the upper material rack 8 are inserted into the support holes 28 on the lower second ring body 22; When preparing sewage samples outside the sewage continuous detection equipment, multiple test tubes 9 can be stacked up and down. First, the test tubes 9 are placed one by one in the test tube holder 11 of the lower layer, and then the second ring body 22 is installed on the upper end of the test tube holder 11 of the lower layer. Then, the first ring body 10 of the second layer is placed on the second ring body 22 of the first layer, that is, the positioning pin 16 is embedded in the support hole 28, and then the test tube holder 11 and the test tube 9 are placed on the first ring body 10 of the second layer. And so on, stacking layer by layer to form a Figure 14 and Figure 15 In the state shown, the stacking structure is set up, and the test tubes 9 to be tested can be stacked together, and the test tubes 9 that have been tested can also be stacked together, saving space and reducing the occupation of the operating space by the sewage sample; at the same time, when the No. 1 ring body 10 is placed in the rotating trough 7, the No. 1 ring body 10 on the upper layer can be directly moved, which is convenient to operate.

[0026] Reference Figure 11-13 Each of the test tube holders 11 has a symmetrically formed sliding hole 29 on the outer ring of the upper end. The sliding hole 29 is provided close to the anti-slip portion 25. The lower end of each spring piece 21 in each test tube holder 11 is fixed to the bottom of the test tube holder 11. The upper end of each spring piece 21 is inclined along the sliding hole 29 and passes through the bottom of the through hole 26. The upper end of the spring piece 21 is in a free state. During the process of inserting the lower end of the test tube 9 into the test tube holder 11, the lower end of the test tube 9 can expand the spring piece 21 outward, so that the spring piece 21 adapts to the diameter of the test tube 9. At the same time, when the No. 2 ring body 22 is installed on the test tube holder 11, the insertion rod 24 is inserted into the through hole 26, and the outer circle of the insertion rod 24 squeezes the upper end of the spring piece 21. At this time, the extrusion force of the upper end of the spring piece 21 on the outer wall of the test tube 9 will be increased, which can further improve the extrusion stability of the spring piece 21 on the test tube 9. In order to ensure the fit between the spring piece 21 and the test tube 9, a rubber layer can be provided on the surface of the spring piece 21, which can not only improve the extrusion effect of the spring piece 21 on the test tube 9, but also further improve the stability of the test tube 9 in the test tube holder 11.

[0027] Reference Figure 10-13 Each of the insertion rods 24 is arranged in a truncated cone shape, and a ring-shaped groove 30 is radially opened on the outer ring of the bottom of each insertion rod 24. The insertion rod 24 is inserted into the through hole 26, and the upper end of the spring piece 21 slides into the groove 30 along the outer ring of the lower end of the insertion rod 24, and the groove 30 squeezes the upper end of the spring piece 21; When the insertion rod 24 is inserted into the through hole 26, the upper end of the spring piece 21 slides along the outer ring of the insertion rod 24 and slides into the groove 30. At this time, the upper end of the spring piece 21 is stuck in the groove 30, restraining the relative sliding between the insertion rod 24 and the through hole 26, that is, restraining the No. 2 ring body 22 on the test tube holder 11. When multiple test tubes 9 are shaken at the same time, the No. 2 ring body 22 is also difficult to separate from the test tube holder 11, thereby improving the safety of the test tubes 9. At the same time, the groove 30 also restrains the spring piece 21, so that the spring piece 21 can be firmly squeezed into the test tube 9. The insertion rod 24 and the spring piece 21 complement each other.

[0028] Reference Figure 3-Figure 15 , each of the notches 18 and the bottom of each of the support holes 28 is provided with an iron block; each of the latches 19 is made of a magnetic material capable of absorbing the iron block; The No. 1 ring body 10, the No. 2 ring body 22 and the test tube holder 11 are all made of plastic material, which is light as a whole and convenient for shaking multiple test tubes 9. An iron block is set in each notch 18 and each support hole 28. The iron block is matched with a pin 19 that can absorb the iron block. When the test tube holder 11 is installed on the No. 1 ring body 10, the pin 19 is fixed in the notch 18 by adsorption. At the same time, an iron block is also fixed in each positioning groove 15, and the positioning pin 16 on the lower end surface of the No. 1 ring body 10 is also made of a magnetic material that can absorb the iron block. The No. 1 ring body 10 is installed on the outer gear ring 12. On the top, the positioning pin 16 is embedded in the positioning groove 15, and the positioning pin 16 absorbs the iron block, thereby improving the stability between the No. 1 ring body 10 and the outer gear ring 12. When the servo motor drives the No. 1 ring body 10 to rotate intermittently clockwise and counterclockwise, the No. 1 ring body 10 can still be stable on the outer gear ring 12. At the same time, when multiple layers of test tubes 9 are stacked, the positioning pin 16 of the upper No. 1 ring body 10 is embedded in the support hole 28 on the lower No. 2 ring body 22, which can improve the stability between the upper and lower adjacent No. 1 ring bodies 10 and No. 2 ring bodies 22, so that the stacked test tubes 9 can be stabilized.

Since the water quality detector probe 6 detects sewage samples according to the principle of spectrophotometry, it needs to be detected under certain light-proof conditions. For example, in a laboratory, the light is not as sufficient as natural light, and the detection can be carried out directly. If the operation is carried out outdoors, there is sufficient light, and the light-shielding detection is required through the protective plate 31; rotate open the cover 32, and then remove the other protective plate 31. Since the other protective plate 31 is adsorbed on the operating table 3 by a magnet, the protective plate 31 can be removed directly, and then the No. 1 ring body 10 is placed, and then the other protective plate 31 is installed and reset, and the cover 32 is rotated to cover the top of the test tube 9, covering the entire sewage continuous detection equipment for sewage detection.

[0030] Reference Figure 11 Each of the spring pieces 21 and the extrusion surface of the test tube 9 are arranged in an arc shape; the shape of the spring piece 21 allows the spring piece 21 to be further attached to the surface of the test tube 9, further improving the clamping effect of the spring piece 21 on the test tube 9, and further improving the stability of the test tube 9 in the test tube seat 11.

Specifically, the positioning pin 16 on the lower surface of the No. 1 ring body 10 is embedded in the positioning groove 15 on the outer gear ring 12. The No. 1 ring body 10 rotates synchronously with the outer gear ring 12, and the outer gear ring 12 is intermittently driven to rotate by a servo motor controlled by a PLC, so that each test tube 9 is opposite to the water quality detector probe 6. The water quality detector probe 6 detects the sewage sample in the test tube 9 through the detection window 20 on the test tube holder 11.
