DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0028] A water quality online monitor for multi-point sampling of a water pipe comprises a sampling tube 1. A filtering mechanism 2 is arranged at the bottom end of the sampling tube 1. The filtering mechanism 2 comprises a rotating locking groove 201, a filtering frame 202, a clamping block 203 and a rotating block 204. The rotating locking groove 201 is arranged on the inner wall of the sampling tube 1. The filtering frame 202 is plugged into the bottom end of the sampling tube 1. The clamping block 203 is fixedly installed on both sides of the top of the filtering frame 202. The rotating block 204 is fixedly installed on the bottom of the filtering frame 202.

[0029] See also Figure 1-5 There are several sampling tubes 1 and filtering mechanisms 2. A detection box 3 is provided at one end of the sampling tube 1. A valve 4 and a sampling pump 5 are provided on each sampling tube 1. A flange 6 is provided on the outer side of the sampling tube 1. The sampling tube 1 is inserted into the inner side of the water pipe and fixed to the water pipe through the flange 6.

[0030] Specifically, the sampling tube 1 is responsible for guiding the water sample from the water pipe to the inside of the monitor. One end of the sampling tube 1 is connected to the inside of the water pipe, and the other end is connected to the subsequent analysis unit. Through the sampling tube 1, the monitor can obtain the water sample in the water pipe in real time, providing a material basis for the subsequent water quality analysis. The filtering mechanism 2 can effectively remove large particles of impurities in the water sample, protect the subsequent analysis unit from contamination, and improve the accuracy and stability of the analysis. The filter frame 202 is plugged into the bottom end of the sampling tube 1 to filter large particles of impurities in the water sample. The block 203 and the rotating block 204 cooperate with the rotating locking groove 201. The filter frame 202 can be fixed and disassembled through a rotating operation, which makes it easy for users to replace the filter frame 202 and improves the convenience of the filter mechanism 2. The valve 4 is used to control the flow of water samples, and the sampling pump 5 is responsible for sucking the water samples from the water pipe into the monitor. The valve 4 and the sampling pump 5 work together to ensure that the water samples can enter the monitor accurately and stably, providing a continuous supply of water samples for water quality analysis. The flange 6 is used to connect the sampling tube 1 and the water pipe to ensure that the sampling tube 1 can be stably inserted into the water pipe. At the same time, the connection stability between the sampling tube 1 and the water pipe is enhanced to prevent water samples from leaking during the sampling process.

[0031] Embodiment 2:

[0032] See also Figure 1-5 The inner cavity of the sampling tube 1 is provided with a cleaning mechanism 7, and the cleaning mechanism 7 is located above the filtering mechanism 2. The cleaning mechanism 7 includes a fixing frame 701, a sleeve 702, a motor 703, a rotating shaft 704, a mounting plate 705 and a brush 706. The fixing frame 701 is fixedly mounted on the inner wall of the sampling tube 1, the sleeve 702 is fixedly mounted on the middle part of the fixing frame 701, the motor 703 is fixedly mounted on the top of the fixing frame 701, the rotating shaft 704 is fixedly connected to the bottom of the motor 703, and is movably mounted on the inner side of the sleeve 702, the mounting plate 705 is fixedly connected to the bottom of the rotating shaft 704, and the brush 706 is fixedly mounted on the bottom of the mounting plate 705.

[0033] Specifically, the cleaning mechanism 7 can regularly clean the filter to prevent impurities and pollutants from accumulating on the filter, maintain the filtering effect of the filter and the unobstructed cleaning of the sampling tube 1, and improve the accuracy of water quality analysis. The motor 703 drives the rotating shaft 704 to rotate, driving the mounting plate 705 and the brush 706 to rotate in the sampling tube 1, thereby cleaning the surface of the filter.

[0034] Working principle: First, the sampling tube 1 is stably inserted into the water pipe through the flange 6 to ensure that the water sample can smoothly enter the sampling tube 1. Each sampling tube 1 is equipped with a valve 4 and a sampling pump 5. The valve 4 is used to control the flow of the water sample, and the sampling pump 5 is responsible for sucking the water sample from the water pipe into the monitor. When the sampling pump 5 is started, it will extract the water sample and transport it to the subsequent analysis unit through the sampling tube 1. Before the water sample enters the analysis unit, it will first pass through the filtering mechanism 2. The filter frame 202 of the filtering mechanism 2 is plugged into the bottom end of the sampling tube 1 to filter large particles of impurities in the water sample. The block 203 and the rotating block 204 cooperate with the rotating locking groove 201 to ensure that the filter frame 202 can It is firmly fixed in the sampling tube 1. When the filter frame 202 needs to be replaced, the user can remove and install a new filter frame 202 by rotating it, which makes the maintenance of the entire filter mechanism 2 simple and convenient. The filtered water sample will continue to flow upward. When the motor 703 is started, it will drive the shaft 704 to rotate in the sleeve 702. The rotation of the shaft 704 will drive the mounting plate 705 and the brush 706 to rotate together, thereby cleaning the surface of the filter screen, thereby removing impurities and pollutants attached to the filter screen, ensuring the filtering effect on the filter screen, and improving the accuracy of water quality analysis. Finally, the filtered and cleaned water sample will enter the detection box 3 for subsequent water quality analysis.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
