Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling and testing equipment, in particular to water quality sampling and testing equipment with automatic impurity removal. Background Art

[0002] Water quality testing is an important task for many places, such as whether drinking water meets water quality standards, whether factory wastewater meets discharge standards, whether pond water quality is harmful to organisms, etc. Sampling and testing equipment plays an important role in the water quality testing process.

[0003] The Chinese patent authorization publication number is CN220120800U, which discloses a water quality sampling and testing device for sewage treatment, including a bottom plate, and the four corners of the top of the bottom plate are fixedly connected to support columns, and the top of the support column is fixedly connected to a workbench. In the utility model, the first threaded rod is driven to rotate by a synchronous motor, so that the slider slides in the slide groove, the support plate moves forward, and the servo motor drives the first gear to rotate, so that the second threaded rod moves up and down, which solves the problem that the water quality is inaccurate during sampling due to different depths during sampling and different results during detection. In addition, the micro water pump allows water to enter the water storage tank through a hose, and cooperates with the telescopic water pipe to flow the water into the test tube, which solves the problem that the water quality sample extracted by the equipment needs to be manually poured into the test tube during water quality sampling, saving time and effort.

[0004] Most of the existing technical solutions have the following defects: they do not have a good filtering effect on impurities mixed in the water during sampling, and do not have a good automatic scraping function for the impurities after filtering, which reduces the overall convenience of use. Therefore, the utility model provides a water quality sampling and testing equipment with automatic impurity removal to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a water quality sampling and testing device with automatic impurity removal, so as to solve the problem proposed in the above background technology that the impurities mixed in the water are not filtered well during sampling, and the impurities after filtering are not automatically scraped off, which reduces the overall convenience of use.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a water quality sampling and testing device for automatic impurity removal, comprising a mounting base, a mounting column integrally fixedly mounted on the outer side of the upper end of the mounting base, and a fixing frame mounted on the outer end of the mounting column, and also comprising:

[0007] A support plate is integrally fixedly mounted on the outer wall end of the fixing frame, and a first bolt is penetrated inside the front end of the fixing frame, a sampling cylinder is penetrated inside the left side of the support plate, and a water pump is installed on the upper surface of the sampling cylinder, the output end of the water pump is connected to a connecting pipe located inside the upper end of the sampling cylinder, and the right end of the water pump is connected to a water outlet pipe;

[0008] A filter screen is installed on the outer side of the lower end of the sampling barrel, and a second bolt is provided through the connection between the filter screen and the sampling barrel. A fan blade is installed on the inner lower end of the sampling barrel through a bearing, and a connecting rod is coaxially connected to the outer side of the lower end of the fan blade, and a scraper is fixedly installed on the outer side of the lower end of the connecting rod.

[0009] Preferably, the fixing frame is connected to the mounting column in a sliding manner, and threaded holes matching the first bolts are provided at equal intervals inside the front end of the mounting column.

[0010] Preferably, a clamping frame is fixedly mounted on the outer side of the middle portion of the support plate, a sampling tube is placed inside the clamping frame, and the right end of the water outlet pipe is placed inside the sampling tube.

[0011] Preferably, the diameter of the lower end of the sampling tube is smaller than the diameter of the upper end thereof, and the lower end of the sampling tube is open.

[0012] Preferably, the sampling cylinder and the filter screen are connected in a snap-fit ​​manner, and the filter screen forms a detachable structure with the sampling cylinder via a second bolt.

[0013] Preferably, the connecting rod forms a rotating structure in the sampling tube, and the scraper connected to the lower end of the connecting rod is in contact with the outer side of the lower end of the filter screen.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the water quality sampling and testing equipment with automatic impurity removal has a good filtering effect on impurities mixed in water during sampling, and has a good automatic scraping function for impurities after filtration, which is convenient for improving the overall convenience of use;

[0015] The fixing frame is connected to the mounting column in a sliding manner. When adjusting, the first bolt can be rotated first, so that the first bolt is threadedly connected with the threaded hole and the fixing frame respectively and then separated. At this time, the first bolt loses its fixing effect on the fixing frame, so that the fixing frame can move outside the mounting column, so that the height of the support plate and the sampling tube can be adjusted through the fixing frame, which is convenient for putting the sampling tube into the water;

[0016] A water pump is set to start, so that the water pump can change the negative pressure in the sampling tube through the connecting pipe, so that water can be injected into the sampling tube, and injected into the sampling tube through the connecting pipe, the water pump and the water outlet pipe, so that the sampling tube can store water samples and facilitate subsequent testing. When water is injected into the sampling tube, the filter net can filter the water to remove impurities mixed in the water and prevent impurities from entering the sampling tube;

[0017] A connecting rod is arranged in the sampling tube to form a rotating structure, and a scraper connected to the lower end of the connecting rod is in contact with the outer side of the lower end of the filter. At this time, the fan blade can rotate in the sampling tube through the bearing under the action of the water flow and drive the connecting rod and the scraper to rotate synchronously, thereby facilitating the scraper to automatically scrape away the impurities filtered by the filter and avoiding the impurities being adsorbed on the outer side of the filter.

[0023] 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.

[0024] See also Figure 1-4The utility model provides a technical solution: an automatic impurity removal water quality sampling and testing equipment, comprising a mounting base 1, and a mounting column 2 integrally fixedly mounted on the outer side of the upper end of the mounting base 1, and a fixing frame 3 mounted on the outer end of the mounting column 2, and also comprising a support plate 4 integrally fixedly mounted on the outer wall end of the fixing frame 3, and a first bolt 5 is penetrated inside the front end of the fixing frame 3, a sampling tube 9 is penetrated inside the left side of the support plate 4, and a water pump 10 is installed on the upper surface of the sampling tube 9, the output end of the water pump 10 is connected to a connecting pipe 11 located inside the upper end of the sampling tube 9, and a water outlet pipe 12 is connected to the right end of the water pump 10, threaded holes 6 matching the first bolt 5 are opened at equal intervals inside the front end of the mounting column 2, a clamping frame 7 is fixedly mounted on the outer side of the middle part of the support plate 4, and a sampling tube 8 is placed inside the clamping frame 7, and the right end of the water outlet pipe 12 is placed inside the sampling tube 8;

[0025] At the same time, the filter screen 13 is installed on the outer side of the lower end of the sampling tube 9, and a second bolt 14 is provided through the connection between the filter screen 13 and the sampling tube 9, a fan blade 15 is installed on the inner lower end of the sampling tube 9 through a bearing, and a connecting rod 16 is coaxially connected to the outer side of the lower end of the fan blade 15, and a scraper 17 is fixedly installed on the outer side of the lower end of the connecting rod 16, the combination of which constitutes a water quality sampling and detection equipment for automatic impurity removal.

[0026] When using the automatic impurity removal water quality sampling and testing equipment, the specific Figure 1 and Figure 3 As shown in, first, the whole is stably placed next to the water quality to be sampled, so that the sampling tube 9 is located directly above the sampled water quality, and the height of the sampling tube 9 is adjusted according to the depth of the required sampling. Since the fixing frame 3 and the mounting column 2 are connected in a sliding manner, when adjusting, the first bolt 5 can be rotated first, so that the first bolt 5 is threadedly connected and separated with the threaded hole 6 and the fixing frame 3 respectively. At this time, the first bolt 5 loses its fixing effect on the fixing frame 3, so that the fixing frame 3 can move on the outside of the mounting column 2, so that the height of the support plate 4 and the sampling tube 9 can be adjusted by the fixing frame 3, so that the sampling tube 9 is conveniently placed in the water. After the adjustment is completed, the first bolt 5 is rotated and inserted into the fixing frame 3 and the threaded hole 6 at the specified height, so as to facilitate the fixing of the fixing frame 3;

[0027] Specific as Figure 1 , Figure 2 and Figure 4As shown in , when sampling, first insert the sampling tube 8 into the clamping frame 7, and put the right end of the water outlet pipe 12 into the sampling tube 8. At this time, the sampling barrel 9, the connecting pipe 11 and the water outlet pipe 12 are connected, and then the water pump 10 is started, so that the water pump 10 can change the negative pressure in the sampling barrel 9 through the connecting pipe 11, so that water can be injected into the sampling barrel 9, and injected into the sampling tube 8 through the connecting pipe 11, the water pump 10 and the water outlet pipe 12, so that the sampling tube 8 can store water samples and facilitate subsequent detection work. Before use, the two sets of filter screens 13 can be fixedly installed on the outer side of the lower end of the sampling barrel 9 by the second bolts 14 respectively;

[0028] When water is injected into the sampling tube 9, the filter 13 can filter the water to remove impurities mixed in the water and prevent impurities from entering the sampling tube 9. Since the connecting rod 16 forms a rotating structure in the sampling tube 9, and the scraper 17 connected to the lower end of the connecting rod 16 is in contact with the outer side of the lower end of the filter 13, the fan blade 15 can rotate in the sampling tube 9 through the bearing under the action of the water flow and drive the connecting rod 16 and the scraper 17 to rotate synchronously, so that the scraper 17 can automatically scrape off the impurities filtered by the filter 13 to prevent impurities from being adsorbed on the outer side of the filter 13. This is the method of using the water quality sampling and detection equipment with automatic impurity removal.
