Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling equipment, in particular to a water quality sampling device used in water quality testing. Background Art

[0002] Water is one of the fundamental substances of life, essential for sustaining life and indispensable to our daily lives. However, with the rapid development of modern industrial technology, water pollution has become increasingly prominent due to a series of factors, including overexploitation of resources and environmental damage. Environmental protection has received widespread attention from the entire society. Therefore, in our daily lives and production processes, we need to continuously test water quality to ensure that the water used meets the needs of production and life. During the water quality inspection process, it is usually necessary to use a water sampling device to collect water samples from surface water such as lakes and reservoirs. The collected water quality is then tested using water quality testing instruments to assess the water pollution level.

[0003] In the process of water quality sampling, since the sampled water samples need to be transported and other substances need to be avoided from interfering with the quality of the sampled samples during the sampling process, we need the sampling tube to be able to be opened underwater when in use, and also to be sealed. When using a traditional sampling device, one end of the sampling tube is usually put into the water, and sampling is performed by negative pressure pumping. However, when using this sampling device, there are problems such as: when in use, the sampling tube needs to be put into the water multiple times, and water samples of different depths need to be obtained through multiple sampling. The operation is cumbersome and the water quality sampling efficiency is low. At the same time, during the sampling process, the sampling tube inlet is filtered. If there are many floating objects in the water, it is easy to cause the sampling tube inlet to be blocked, thereby affecting the water pumping sampling and other problems.

[0004] Based on this, the utility model proposes a water quality sampling device for water quality testing to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0005] In view of this, the main purpose of the present invention is to provide a water quality sampling device for water quality testing to solve the problems of low sampling efficiency and easy clogging of the sampling tube inlet in traditional sampling devices.

[0038] As the instruction manual Figures 1-6 As shown, the utility model provides a technical solution:

[0039] A water quality sampling device for water quality testing comprises a measuring frame 1, a mounting frame 2 and a sampling mechanism 3; wherein:

[0040] The measuring frame 1 is a movable frame structure;

[0041] The mounting frame 2 is slidably mounted on the measuring frame 1 and is used in conjunction with a driving assembly mounted on the measuring frame 1 to adjust the height of the mounting frame 2 on the measuring frame 1 through the driving assembly;

[0042] The sampling mechanism 3 is installed at the lower end of the surface of the mounting frame 2 and is used for water quality sampling.

[0043] It should be noted that in this embodiment, through the arrangement of the above-mentioned measuring frame 1, mounting frame 2 and sampling mechanism 3, a movable device is formed after assembly, in which the sampling height of the mounting frame 2 can be easily adjusted and water quality sampling can be performed, so as to facilitate carrying during use and meet water quality sampling under different sampling requirements.

[0044] As a preferred embodiment, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the sampling mechanism 3 includes a collecting cylinder 31, a sampling cylinder 32, a connecting disk 34 and a first servo motor 37; wherein:

[0045] The collecting cylinder 31 is mounted on the lower end of the surface of the mounting frame 2 and is fixed by the mounting frame 2;

[0046] The sampling cylinder 32 is installed in an annular shape on the inner bottom wall of the collecting cylinder 31, and a sealing disk 33 is fixedly connected to the upper end of the surface of the sampling cylinder 32;

[0047] The connecting disk 34 is rotatably mounted on the top of the blocking disk 33, and the bottom end of the connecting disk 34 contacts the top end of the blocking disk 33. The top end of the connecting disk 34 is connected to a trumpet-shaped water inlet 35, and the upper end of the inner wall of the trumpet-shaped water inlet 35 is fixedly connected to a filter screen 36.

[0048] The first servo motor 37 is fixedly mounted on the bottom end of the connecting disk 34 , and a sealing bearing 314 is fixedly connected to the upper end of the inner wall of the collecting cylinder 31 . The inner edge of the sealing bearing 314 is fixedly connected to the surface of the connecting disk 34 .

[0049] It should be noted that in this embodiment, through the arrangement of the collection cylinder 31, sampling cylinder 32, connecting disk 34, and first servo motor 37, multiple water quality samples can be collected using multiple sampling cylinders 32. The first servo motor 37 drives the connecting disk 34 to rotate, allowing the corresponding sampling cylinder 32 to be sampled. After sampling, the corresponding sampling cylinder 32 can be immediately sealed to prevent contamination of the sample during removal and transport. The filter 36 effectively filters impurities, ensuring convenient sampling.

[0050] As a preferred embodiment, Figure 1 and Figure 2 As shown, the drive group includes a screw rod rotatably installed in the measuring frame 1, the top end of the screw rod is fixedly connected to a second servo motor, the top end of the second servo motor is fixedly connected to the inner top wall of the measuring frame 1, and a scale line is provided at the front end of the measuring frame 1.

[0051] It should be noted that, in this embodiment, through the arrangement of the above-mentioned structure, when it is necessary to sample and test the water quality in the reservoir, after pushing the measuring frame 1 to move to the water quality sampling location, the second servo motor is turned on, and the output shaft of the second servo motor rotates to drive the screw to rotate. After the screw rotates to drive the mounting frame 2 and the collecting cylinder 31 to move down to a corresponding height, the second servo motor is turned off and the first servo motor 37 is turned on. The output shaft of the first servo motor 37 rotates to drive the connecting disk 34 and the trumpet-shaped water inlet 35, so that the bottom end of the trumpet-shaped water inlet 35 moves to the top end of one of the sampling cylinders 32 to open. At the mouth, the water in the reservoir is filtered through the filter screen 36 and flows into one of the sampling tubes 32. After one of the sampling tubes 32 is filled with water, the first servo motor 37 is turned on, and the output shaft of the first servo motor 37 rotates the connecting disk 34, the trumpet-shaped water inlet 35 and the support rod 312 to a proper angle. At this time, the bottom outlet of the trumpet-shaped water inlet 35 contacts the blocking disk 33, blocking the water from flowing into the sampling tube 32. According to the above process, the water quality of different depths in the reservoir can be sampled at one time, and there is no need to adjust the collecting tube 31 away from the water multiple times to take out the water quality in the sampling tube 32.

[0052] As a preferred embodiment, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a support rod 312 is fixedly installed on the top of the connecting disk 34, and a ring-shaped fixed rod 310 is fixedly connected to the upper end of the surface of the collecting cylinder 31. A baffle 311 is fixedly connected to one end of the fixed rod 310. The sealing disk 33 and the baffle 311 are both rubber components.

[0053] It should be noted that, in this embodiment, by turning on the first servo motor 37, the output shaft of the first servo motor 37 rotates to drive the connecting disk 34, the trumpet-shaped water inlet 35 and the support rod 312 to rotate. When the support rod 312 rotates and contacts the side of one of the baffles 311, the support rod 312 is subjected to resistance, and the first servo motor 37 is automatically closed, so that the bottom end of the trumpet-shaped water inlet 35 is facing the top opening of one of the sampling tubes 32 for sampling.

[0054] As a preferred embodiment, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a ring-shaped cleaning block 38 is fixedly installed on the upper end of the surface of the collecting cylinder 31, the bottom of the cleaning block 38 contacts the top of the filter 36, and a plurality of railings 39 distributed in equal rows are fixedly installed on the top of the cleaning block 38.

[0055] It should be noted that, in this embodiment, the railing 39 can prevent large impurities in the water from adhering to the filter 36, so that the water in the reservoir can flow into the corresponding sampling tube 32, and the cleaning block 38 can scrape the top of the moving filter 36 to prevent excessive small impurities from adhering to the top of the filter 36.

[0056] As a preferred embodiment, Figure 4 As shown, the lower end of the surface of the sampling cylinder 32 passes through the collecting cylinder 31 and is threadedly connected to a sealing cover 313.

[0057] It should be noted that, in this embodiment, after the collecting cylinder 31 has collected the water at different depths of the reservoir, the collecting cylinder 31 is driven to move upward and away from the water. At this time, the sealing cover 313 is rotated one by one, so that the water sampled in each sampling cylinder 32 flows into the water quality testing instrument. At this time, the water quality testing instrument begins to test the water quality at different depths in the reservoir, so that the staff can understand the water quality of the reservoir so that they can take corresponding measures later.

[0058] As a preferred embodiment, Figure 5 As shown, the upper end of the inner wall of the collecting cylinder 31 is fixedly connected to a mounting frame, and the bottom end of the first servo motor 37 is fixedly connected to the inner wall of the mounting frame to fix the first servo motor 37.

[0059] When the water quality sampling device for water quality testing of the utility model is used:

[0060] After pushing the measuring frame 1 to move to the water quality sampling location, the second servo motor is turned on. The output shaft of the second servo motor rotates and drives the mounting frame 2 and the collecting tube 31 to move down to a corresponding height through the screw rod. The second servo motor is then turned off and the first servo motor 37 is turned on. The output shaft of the first servo motor 37 rotates to drive the connecting plate 34, the trumpet-shaped water inlet 35 and the support rod 312 to rotate. When the support rod 312 rotates and contacts the side of one of the baffles 311, the support rod 312 is subjected to resistance, and the first servo motor 37 is automatically closed, so that the bottom end of the trumpet-shaped water inlet 35 is facing the top opening of one of the sampling tubes 32 for sampling. At this time, the water in the reservoir is filtered through the filter 36 and flows into After one of the sampling cylinders 32 is filled with water, the first servo motor 37 is turned on again. Since the baffle 311 of the rubber component can be deformed, the output shaft of the first servo motor 37 rotates the connecting disk 34, the trumpet-shaped water inlet 35 and the support rod 312 to rotate at a proper angle, so that the support rod 312 rotates to squeeze one of the baffles 311 and move away. The first servo motor 37 is turned off. At this time, the bottom outlet of the trumpet-shaped water inlet 35 contacts the sealing disk 33, blocking water from flowing into the sampling cylinder 32. According to the above process, water quality at different depths in the reservoir can be sampled at one time, and there is no need to adjust the collecting cylinder 31 away from the water multiple times to take out the sample in the sampling cylinder 32.

[0061] It should be noted that the measuring frame 1, mounting frame 2, first servo motor 37, second servo motor and sealed bearing 314 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the first servo motor 37 and the second servo motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
