Description

Technical Field

[0001] The invention relates to the technical field of mineral water pretreatment water quality detection, in particular to a sampling machine used for mineral water pretreatment water quality detection. Background Art

[0002] A handheld water sampler is a portable device used to collect and analyze various physical, chemical and biological parameters in water. It can be used in the field, laboratory or other field environments to obtain water quality information quickly and easily. Handheld water samplers usually include functions such as sample collection, filtration, measurement and data recording, providing real-time, accurate and reliable data for water quality monitoring;

[0003] There are still the following defects in specific use:

[0004] 1. When sampling water quality, if the existing handheld water sampler is uneven, that is, the distribution of substances in the water is uneven, such as suspended matter, dissolved oxygen, etc., then in the absence of mixing and stirring, the sampled water may not represent the average water quality of the entire water body, which will lead to deviations in the sampling results and affect the accurate assessment of water quality. Secondly, some physical and chemical parameters in the water body will change over time, such as dissolved oxygen content, pH value, etc. If no mixing and stirring is performed, the time point and location selected during sampling cannot fully represent the water quality characteristics of the entire sampled water body, thereby affecting the comprehensive assessment of water quality.

[0005] 2. In addition, there are some larger particles in the water, such as mud, algae, etc. If these particles directly enter the water quality sampler, it will cause the filter device to be blocked, affecting the normal operation of the sampler and damaging the filter device of the handheld water quality sampler. In addition, the filter device of the water quality sampler itself is blocked or damaged by the particulate matter, resulting in the particulate matter and suspended matter in the sampled water not being effectively removed, affecting the accuracy and reliability of subsequent water quality analysis.

[0006] In view of this, the present invention proposes a sampling machine for mineral water pretreatment water quality detection to make up for and improve the deficiencies of the prior art. Summary of the invention

[0013] Furthermore, the second gear meshes with the first gear, the first gear and the second gear are made of alloy, the stirring blade is in the shape of a paddle, and the stirring blade is made of stainless steel.

[0014] Furthermore, a circular arc groove is opened on the central outer wall of the support column, the fixed shaft is rotatably connected to the inside of the circular arc groove, and the support column is fixedly installed on the bottom outer wall of the annular block.

[0015] Furthermore, the filtering mechanism includes a supporting block fixedly mounted on the bottom end surface of the annular block, an inner wall of the supporting block on a side away from the annular block is provided with an open groove, a slider is slidably connected to the inside of the open groove, a spring is fixedly mounted on the outer wall of the slider, two springs are symmetrically arranged around the central axis of the slider, a connecting shaft is fixedly mounted through the surface of the open groove on one side away from the spring, an eccentric block is fixedly mounted on the outer wall of one end of the connecting shaft away from the spring, a second driving shaft is fixedly mounted on the end of the connecting shaft close to the bidirectional motor, and a screen is fixedly mounted on the outer wall of the bottom end of the spring.

[0016] Furthermore, one end of the two springs away from the slider is fixedly mounted on the inner wall of the support block, and the material of the two springs is stainless steel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention utilizes the first gear and the second gear and the stirring blade to cooperate with each other. The stirring mechanism can evenly mix the unevenly distributed pollutants in the water sample, thereby improving the representativeness and accuracy of the sampling. At the same time, some pollutants may not be easily dissolved in water. Adding a stirring mechanism can help them to be better dissolved in water, thereby more accurately measuring the water quality. The stirring mechanism can also speed up the mixing process of the water sample, saving sampling time and improving sampling efficiency. Moreover, some water samples have stratification, that is, the concentrations of different components in the water are different at different depths. Adding a stirring mechanism can avoid sample stratification and ensure that a representative water sample is collected.

[0021] (2) The present invention utilizes the connection shaft, the slider, the open slot body and the screen to cooperate with each other. The vibration of the screen can help the mineral water to generate jumping motion on the screen, which promotes the impurities in the water to be more easily isolated and separated, thereby improving the separation efficiency. Secondly, there may be some tiny particles or impurities in the mineral water, which are easy to block the pores of the screen. The vibration of the screen can effectively prevent the clogging of the screen holes, ensure the smooth passage of water, and help separate smaller particles and impurities through the vibration of the screen, so that the mineral water is clearer and more transparent, and the water quality is improved. At the same time, the vibration of the screen can quickly and effectively separate impurities, save manpower and time, and improve production efficiency. The filtering mechanism can filter out impurities and suspended solids in the water sample, such as particulate matter and suspended bacteria, so as to reduce interfering substances in the sampled sample and improve the purity and accuracy of the sample. At the same time, the filtering mechanism can prevent large particles or impurities from entering the water quality sampler, avoid clogging and damage to the water quality sampler, and thus extend the service life of the water quality sampler. At the same time, water quality sampling through the filtering mechanism can reduce subsequent sample processing work. After the sample is purified, no additional filtering steps are required, saving time and labor.

[0022] (3) The present invention utilizes a fixed axis and a scoop net to cooperate with each other. The scoop net can help expand the scope of water quality sampling, and is particularly suitable for sampling in large areas of water or deep water areas. The scoop net can be used to obtain samples in the water body more comprehensively. In some waters, there are large particles of pollutants, such as floating objects, suspended matter, etc. The scoop net can effectively capture these large particles so that they will not interfere with the operation and results of the water quality sampler. The scoop net can be used to perform preliminary screening and pretreatment of large particles in the water body, filter out larger impurities, reduce the burden on subsequent water quality samplers, and help improve sampling efficiency and accuracy. The scoop net can also improve the efficiency of water quality sampling, especially in waters where a large number of samples need to be collected or where an area is large, so that more water samples can be quickly obtained through the scoop net.

The scoop net 444 is made of rubber. The scoop net 444 can scoop up large particles of impurities in the water by rotating the fixed shaft 26. The scoop net 444 can help expand the scope of water quality sampling, and is particularly suitable for sampling in large areas of water or deep water areas. The scoop net 444 can be used to obtain samples in the water body more comprehensively. In addition, there may be large particles of pollutants in some waters, such as floating objects, suspended matter, etc. The scoop net 444 can effectively capture these large particles so that they will not interfere with the operation and results of the water quality sampler 1.

[0046] The following are the complete usage steps and working principles of the above embodiment:

[0047] The device is mainly used for: Figure 1 As shown, the operator first prepares the required water sampler 1 and equipment, checks their status and integrity; prepares a sampling container, such as a sampling bottle, and then adjusts the gap size of the pump head 12 by turning the adjustment handle 13 to make the silicone tube 14 stuck in the pump head 12, and then puts the water sampler 1 into the water, ensuring that the sampling sink 15 is at an appropriate depth to prevent air from entering, and then the operator holds the water sampler 1 and starts the switch 11, extracts the water sample into the silicone tube 14 and then into the sampling container, ensuring that the sampling flow rate and time meet the requirements;

[0048] Stirring mechanism 2 is used to help mix dissolved matter, suspended matter, etc. in water evenly, so as to obtain more accurate and representative water quality samples. When used specifically:

[0049] like Figure 3As shown, when the sampling sink 15 is at an appropriate depth of water, during the water sampling process, the operator starts the bidirectional motor 22 by starting the button on the controller operation panel through the controller equipped with the bidirectional motor 22. Since the first drive shaft 23 is fixedly installed at the output end of one end of the bidirectional motor 22, and the first gear 24 is fixedly installed on the outer wall of the first drive shaft 23, the start of the bidirectional motor 22 will drive the first drive shaft 23 to rotate, and the rotation of the first drive shaft 23 will also drive the first gear 24 to rotate. In addition, the end of the first drive shaft 23 away from the first gear 24 is rotatably connected to the connecting rod 25, and the end of the connecting rod 25 away from the first gear 24 is rotatably connected to the fixed shaft 26, and the top of the fixed shaft 26 is fixedly installed with a second gear 27, as shown in FIG. Figure 4 As shown, the rotation of the bidirectional motor 22 will synchronously drive the fixed shaft 26 and the second gear 27 to rotate, and the second gear 27 is meshed with the first gear 24, and then with the rotation of the first gear 24, the second gear 27 will drive the fixed shaft 26 and the connecting rod 25 to rotate around the outer wall of the first gear 24, so that a stirring blade 28 is fixedly installed at the bottom end of the fixed shaft 26, and then the rotation of the fixed shaft 26 will jointly drive the stirring blade 28 to rotate to achieve stirring in the water, and in addition, the stirring blade 28 is connected to the second gear 27 and moves around the first gear 24, so that a more uniform stirring effect can be achieved, and the stirring blade 28 moves around the first gear 24 connected to the second gear 27 to make the stirring action more comprehensive, ensuring that the mixture is evenly mixed in the entire container, and at the same time, compared with the stirring method directly connected to the output end of the bidirectional motor 22, stirring through gear transmission can more effectively utilize the output power of the bidirectional motor 22, reduce energy consumption, and because the gear transmission can reduce the load directly connected to the output end of the bidirectional motor 22, it can reduce the wear and damage of the stirring equipment and extend the service life of the equipment;

[0050] Summary 1: Compared with the prior art handheld water quality sampler 1 which lacks mixing and stirring of the sampled water, the present mechanism realizes that as the first gear 24 rotates, the second gear 27 drives the fixed shaft 26 and the connecting rod 25 to rotate around the outer wall of the first gear 24, so that a stirring blade 28 is fixedly installed at the bottom end of the fixed shaft 26, and then the rotation of the fixed shaft 26 drives the stirring blade 28 to rotate to achieve stirring in the water. The stirring mechanism 2 can mix the unevenly distributed pollutants in the water sample evenly, thereby improving the representativeness and accuracy of the sampling. At the same time, some pollutants may not be easily dissolved in water. Adding the stirring mechanism 2 can help dissolve them better in water, thereby more accurately measuring the water quality, and the stirring mechanism 2 can speed up the mixing process of the water sample, save sampling time, and improve sampling efficiency. Moreover, some water samples may have stratification, that is, the concentrations of different components in the water are different at different depths. Adding the stirring mechanism 2 can avoid sample stratification and ensure that representative water samples are collected.

[0051] It is used to filter suspended matter and particulate matter in the water sample to prevent them from entering the filtering mechanism 3 in the water sampler 1. When used specifically:

[0052] like Figure 5As shown, a second driving shaft 37 is fixedly installed at the shaft output end of the other end of the bidirectional motor 22, and a connecting shaft 35 is also fixedly installed at the end of the second driving shaft 37 away from the bidirectional motor 22, so that the operator can drive the connecting shaft 35 to rotate by starting the bidirectional motor 22, and at the same time, an eccentric block 36 is also fixedly installed on the outer wall of the end of the connecting shaft 35 away from the second driving shaft 37, and a slider 33 is fixedly installed on the outer wall of the shaft output end of the connecting shaft 35 close to the bidirectional motor 22, and the slider 33 is slidably connected to the open slot body 32, and a spring 34 is fixedly installed on the outer wall of the slider 33, so that when the connecting shaft 35 rotates, since the eccentric block 36 is fixedly installed on the connecting shaft 35, the rotation of the connecting shaft 35 will cause the screen 38 fixedly installed on the outer wall of the eccentric block 36 to perform centrifugal motion, so that the rotation of the connecting shaft 35 will push the slider 33 to the left inside the open slot body 32 Slide right, and the slider 33 squeezes the spring 34, the screen 38 will vibrate as the slider 33 squeezes the spring 34 left and right inside the open slot 32, and the vibration of the screen 38 can help the mineral water to produce a jumping motion on the screen, which promotes the impurities in the water to be more easily isolated and separated, thereby improving the separation efficiency. Secondly, there may be some tiny particles or impurities in the mineral water, and these particles are easy to block the pores of the screen 38. The vibration of the screen 38 can effectively prevent the blockage of the screen holes, ensuring the smooth passage of water, and the vibration of the screen 38 can help separate smaller particles and impurities, making the mineral water clearer and more transparent, and improving the water quality. At the same time, the vibration of the screen 38 can quickly and effectively separate impurities, saving manpower and time, and improving production efficiency. Furthermore, the vibration of the screen 38 will prevent large particles of impurities in the water from blocking the circular through holes opened on the surface of the screen 38;

[0053] Summary 2: Compared with the prior art which has long relied on the use of the filtering device of the handheld water sampler 1 itself to filter water impurities when sampling, the present mechanism realizes that the rotation of the connecting shaft 35 will push the slider 33 to slide left and right inside the open slot 32 and the slider 33 squeezes the spring 34, so the screen 38 fixedly mounted on the outer wall of the bottom end of the spring 34 will vibrate as the slider 33 squeezes the spring 34 left and right inside the open slot 32. The vibration of the screen 38 can help the mineral water to produce a jumping movement on the screen, which makes it easier to isolate and separate impurities in the water, thereby improving the separation efficiency. Secondly, there may be some tiny particles or impurities in the mineral water, which can easily clog the pores of the screen 38. The vibration of the screen 38 can effectively prevent the clogging of the screen holes, ensuring smooth water flow. The vibration of the screen 38 can help separate smaller particles and impurities, making the mineral water clearer and more transparent, and improving the water quality. At the same time, the vibration of the screen 38 can quickly and effectively separate impurities, saving manpower and time, and improving production efficiency. The filter mechanism 3 can filter out impurities and suspended solids in the water sample, such as particulate matter and suspended bacteria, so as to reduce interfering substances in the sampled sample and improve the purity and accuracy of the sample. At the same time, the filter mechanism 3 can prevent large particles or impurities from entering the water sampler 1, avoiding blockage and damage to the water sampler 1, so as to extend the service life of the water sampler 1. At the same time, water sampling through the filter mechanism 3 can reduce subsequent sample processing work. After the sample is purified, no additional filtering steps are required, saving time and labor.

[0054] The specific use of the scoop net 444 for collecting large impurities in water quality is:

[0055] like Figure 7 As shown, a plurality of scoop nets 444 are fixedly mounted on the outer wall of the fixed shaft 26, so that the rotation of the fixed shaft 26 will drive the scoop nets 444 to rotate together, and a plurality of arc holes are opened on the outer wall of the scoop net 444, so that the scoop net 444 can scoop large particles of impurities in the water through the rotation of the fixed shaft 26;

[0056] Summary 3: Compared with the existing technology that lacks the collection of large particles of impurities in the water, the present mechanism realizes that the large particles of impurities in the water can be collected by rotating the scoop net 444 of the fixed shaft 26. The scoop net 444 can help expand the scope of water quality sampling, and is particularly suitable for sampling in large areas of water or deep water areas. The scoop net 444 can be used to obtain samples in the water body more comprehensively, and some waters may contain large particles of pollutants, such as floating objects, suspended matter, etc. The scoop net 444 can effectively capture these large particles so that they will not interfere with the operation and results of the water quality sampler 1. The scoop net 444 can be used to preliminarily screen and pre-treat the large particles in the water body, filter out larger impurities, reduce the burden on the subsequent water quality sampler 1, and help improve the sampling efficiency and accuracy. The scoop net 444 can improve the efficiency of water quality sampling to a certain extent, especially in waters where a large number of samples need to be collected or where the area is large. More water samples can be quickly obtained through the scoop net 444. When it is necessary to clean the impurities inside the scoop net 444, the scoop net 444 can be disassembled by rotating it, so that it is convenient for the operator to clean the inside of the scoop net 444.
