Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and more specifically, to a device for monitoring the quality of drinking water sources. Background Art

[0002] Drinking water source protection area = surface water drinking water source protection area + groundwater drinking water source protection area. Among them, according to the different types of water bodies where the water intake is located, surface water drinking water sources can be divided into river-type drinking water sources and lake and reservoir-type drinking water sources. Water quality monitoring of drinking water sources is very important.

[0003] The water quality monitoring of drinking water sources is carried out by collecting water samples and using various analytical instruments in the laboratory for testing. When sampling for water quality monitoring, it is necessary to sample water at different depths in layers to ensure the comprehensiveness and accuracy of the water quality monitoring data. The sampling points should be able to reflect the water quality status of the entire drinking water source or water supply system. For some special water sources, such as pollution sources, areas affected by changes in water flow velocity, etc., the sampling points should be evenly distributed throughout the monitoring area to obtain more comprehensive water quality information to evaluate the water quality status of different areas. At present, when conducting stratified sampling of water quality at different depths in the same area and sampling in different areas, samplers are used for multiple sampling. After sampling, the samples need to be collected before the next sampling can be carried out, which is time-consuming and labor-intensive. In view of this, we propose a drinking water source water quality monitoring device. Summary of the invention

When the arc baffle plate 61 is squeezed and contacted with the sealing strip A58, a closed structure is formed to prevent the upper water quality in the water source from mixing when the radial moving mechanism 9 drives the multi-layer water samples to rise.

[0048] In the embodiment of the present invention, the lifting and rotating mechanism 7 includes a motor 71 and a turntable 72. The motor 71 is fixedly mounted on the top of the mounting block 4. The turntable 72 is arranged on the lower rotating groove 41. The turntable 72 is rotatably connected to the lower rotating groove 41 through a swivel 73. A circular cavity 74 is provided on the top of the turntable 72. A rotating column 75 is rotatably connected to the bottom of the turntable 72. A threaded column 76 is fixedly arranged on the bottom of the rotating column 75. The top of the rotating column 75 penetrates into the circular cavity 74 and is fixedly connected to a circular disc 77. The circular disc 77 is provided with a plurality of clamping grooves B78 having the same number as the plurality of clamping grooves A45 in an annular equidistant structure. A connecting shaft 710 is fixedly arranged on the top of the circular disc 77. The top of the connecting shaft 710 penetrates out of the mounting block 4 and is fixedly connected to the output shaft of the motor 71. A limited arc groove 79 is provided at the position of the arc space groove A43, and a linkage plate 70 is slidably connected to the limited arc groove 79. A threaded groove 701 is provided at the centripetal end of the linkage plate 70, and the threaded groove 701 is threadedly connected to the threaded column 76. A rotating guide groove 702 is provided at the centripetal end of the linkage plate 70, and a number of guide ball blocks 65 are movably connected to the rotating guide groove 702.

The present invention adopts the structural design of the lifting and rotating mechanism 7, so that when the straight slide bar 772 slides into the card slot B78, the other end of the straight slide bar 772 disengages from the card slot A45. At this time, the turntable 72 cannot rotate relative to the disk 77. The motor 71 is controlled to rotate by the external control mechanism, so that the connecting shaft 710 drives the disk 77, the rotating column 75, the threaded column 76, the turntable 72 and the linkage plate 70 to rotate, and the position column 773 drives the straight slide bar 772 to slide into the card slot A45. At this time, the other end of the straight slide bar 772 disengages from the card slot B78. At this time, the turntable 72 cannot rotate relative to the turntable 72. The motor 71 is controlled to rotate by the external control mechanism according to the position of the linkage plate 70 at this time, so that the connecting shaft 710 drives the disk 77, the rotating column 75 and the threaded column 76 to rotate. Since the turntable 72 cannot rotate, the threaded column 76 moves relative to the linkage plate 70, causing the linkage plate 70 to rise or fall.

In the further design of the rotating guide groove 702 of the present invention, when the partial threaded guide groove 704 moves relative to the guide ball block 65, the arc baffle 61 of the guide ball block 65 rotates relative to the arc groove 55, so that the water sample can enter the isolation cavity formed by the columnar cavity 54 and the two partition components 66. When the top of the short straight groove 703 contacts the guide ball block 65, the entrance of the isolation cavity is the largest, and when the short straight groove 703 moves relative to the guide ball block 65, the position of the arc baffle 61 remains unchanged, which is conducive to the water sample to quickly enter the isolation cavity located below and improve the sampling efficiency. When the partial threaded guide groove 704 located below moves relative to the guide ball block 65, the arc baffle 61 rotates in the opposite direction until it is squeezed into contact with the sealing strip A58 to form a closed structure, thereby completing the sampling.

[0050] In an embodiment of the present invention, the adjustment mechanism 8 includes an adjustment ring 81, which is arranged in the upper circular groove 42.

A movable ring 83 is movably connected to the guide inclined groove 82. The movable ring 83 is rotatably connected to the top of the guide column 773. An extension block 84 is fixedly provided on the adjustment ring 81 relative to the arc space groove B44. A limited circular groove 85 is provided at the bottom end of the extension block 84. A plug-in assembly 86 is arranged on the limited circular groove 85. The plug-in assembly 86 includes a connecting rod 861. The top end of the connecting rod 861 passes through the arc space groove B44 and is fixedly provided with an adjustment block 862. The bottom end of the connecting rod 861 is plug-fitted with the plug-in circular groove 774. A round block 863 is fixedly provided on the connecting rod 861. The top of the round block 863 is elastically connected to the top of the limited circular groove 85 by a spring 864. Through the structural design of the adjustment mechanism 8 of the present invention, the adjustment block 862 is pinched and lifted up, so that the bottom end of the connecting rod 861 is disengaged from the plug-in circular groove 774, the spring 864 is compressed, and the adjustment block 862 is rotated, so that the extension block 84 drives the adjustment ring 81 to rotate, resulting in a change in the gap position between the guide inclined groove 82 and the card-connecting slide groove C771, causing the guide column 773 to drive the straight slide bar 772 to slide, making the adjustment convenient, saving time and effort.

[0051] Working principle: This embodiment provides a drinking water source water quality monitoring device. When it is necessary to collect water samples at different depths in the same area, pinch the adjustment block 862 and lift it up, so that the bottom end of the connecting rod 861 is disengaged from the plug-in circular groove 774, the spring 864 is compressed, and the adjustment block 862 is rotated, so that the extension block 84 drives the adjustment ring 81 to rotate, causing the gap position between the guide inclined groove 82 and the card-connecting slide groove C771 to change, causing the guide column 773 to drive the straight slide bar 772 to slide into the card-connecting slide groove B78, at which time the other end of the straight slide bar 772 is disengaged from the card-connecting slide groove A45, at which time the adjustment block 862 just moves to the other end of the arc space groove B44, release the adjustment block 862, and under the elastic force of the spring 864, the bottom end of the connecting rod 861 is connected to another plug-in circular groove 774 Plug-in, at this time, the turntable 72 cannot rotate relative to the disc 77, and the motor 71 is controlled to rotate by an external control mechanism, so that the connecting shaft 710 drives the disc 77, the rotating column 75, the threaded column 76, the turntable 72 and the linkage plate 70 to rotate, and the long straight groove 705 directly drives the plurality of guide ball blocks 65 to rotate at the same time, so that the plurality of arc baffles 61 rotate relative to the arc groove 55 together, and the arc slide groove 62 rotates relative to the arc slide bar 63, and the collected water samples enter the plurality of isolation cavities composed of the column cavity 54 and the plurality of interlayer components 66 from the through groove 50, and the motor 71 is controlled to rotate in the opposite direction by an external control mechanism, so that the plurality of arc baffles 61 are all squeezed and contacted with the sealing strip A58 to form a closed structure, so as to prevent the upper water quality in the water source from mixing when the radial moving mechanism 9 drives the multi-layer water sample to rise;

[0052] When it is necessary to collect water samples from different areas multiple times, the same as the above steps, the adjusting block 862 is rotated in the reverse direction, so that the guide column 773 drives the straight slide bar 772 to slide into the card slot A45. At this time, the other end of the straight slide bar 772 is disengaged from the card slot B78. At this time, the turntable 72 cannot rotate relative to the turntable 72. According to the position of the linkage plate 70 at this time, the motor 71 is controlled to rotate through an external control mechanism, so that the connecting shaft 710 drives the disc 77, the rotating column 75 and the threaded column 76 to rotate. Since the turntable 72 cannot rotate, the threaded column 76 moves relative to the linkage plate 70, causing the linkage plate 70 to rise or fall. For example, when the linkage plate 70 is located Figure 2When the locking cam 71 is in the lower position as shown, the threaded column 76 rotates to drive the linkage plate 70 to rise. When the linkage plate 70 rises to the upper part of the threaded guide groove 704 and moves relative to the guide ball block 65, the guide ball block 65 drives the arc baffle 61 located below to rotate relative to the arc groove 55, and the water sample enters the isolation chamber located below. When the top of the short straight groove 703 contacts the guide ball block 65, the entrance of the isolation chamber located below is the largest, and when the short straight groove 703 moves relative to the guide ball block 65, the position of the arc baffle 61 located below remains unchanged, which is conducive to the water sample to quickly enter the isolation chamber located below and improve the sampling efficiency. When the lower part of the threaded guide groove 704 and the guide ball block 65 move relative to each other, the arc baffle 61 rotates in the opposite direction until it is squeezed and contacted with the sealing strip A58 to complete the sampling of this area. Water samples in other areas can be sampled according to the same principle as the sampling method of the isolation chamber located below. It is worth noting that the initial sampling depth of the present invention is controlled by the radial moving mechanism 9.

[0053] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
