Description

Technical Field

[0001] This invention relates to the technical field of water quality testing, and in particular to a water quality testing device. Background Technology

[0002] Water is the source of life, and humans cannot live without it in their daily lives and production activities. The quality of drinking water is closely related to human health. People's requirements for the quality of drinking water are constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly. Testing devices are used when testing water quality.

[0003] In existing water quality monitoring devices, multiple sampling tubes are installed inside the storage unit. The sampling tubes are movable and work together with the sampling unit and the pull-down unit. When water quality needs to be sampled, the sampling unit pulls one sampling tube inward, and the lower end of the sampling tube can be engaged with the upper end of the pull-down unit. The pull-down unit can then pull the sampling tube into the water. When the sampling tube descends to its lowest point, it is opened and vertically inserted into the water. The collection tubes at different heights on the sampling tube can perform stratified sampling. Multiple sampling tubes can be used to sample different water qualities one by one.

[0004] However, in actual testing, when sampling and testing water at different depths, it is necessary to continuously adjust the sampling and testing depth. Furthermore, when testing different areas of the same water body, it is necessary to move the testing device to the corresponding area for testing. This operation is time-consuming and labor-intensive, reducing the efficiency of the testing work. Therefore, there are areas for improvement. Summary of the Invention

[0031] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0032] Reference Figures 1-9 This invention discloses a water quality testing device, including a first fixed frame 1 and a second fixed frame 2. The second fixed frame 2 is located directly above the first fixed frame 1. A vertical rod 6 is connected at the corner between the first fixed frame 1 and the second fixed frame 2. A float 4 is provided on the vertical rod 6 through an adjustment structure. A buoyancy enhancement structure is provided on the float 4. An installation frame 5 is installed below the first fixed frame 1. A driving structure is provided in the middle of the lower part of the first fixed frame 1. A flipping structure is provided in the installation frame 5.

[0033] The flipping structure includes a first through groove 23 in the middle of the mounting frame 5. A second through groove 7 is provided on each of the four side walls of the first through groove 23. A rotating shaft is rotatably connected between the two side walls of the second through groove 7. A flipping handle 9 is fixedly sleeved at both ends of the rotating shaft. A detection structure is provided at the bottom of each flipping handle 9.

[0034] The detection structure includes a fixed cylinder 13 fixedly connected to the bottom end of the flip handle 9. A flip cylinder 3 is installed on the fixed cylinder 13 via a movable structure. An inner rod 11 is movably inserted into the fixed cylinder 13. A limiting structure is provided between the bottom end of the inner rod 11 and the lower inner wall of the flip cylinder 3. A pull-out structure is provided between the top end of the inner rod 11 and the flip handle 9. Multiple detection ports 10 are opened on the side of the fixed cylinder 13. The multiple detection ports 10 are evenly distributed on the fixed cylinder 13. Multiple detection cavities 12 are opened on the inner rod 11. The detection cavities 12 are located below the detection ports 10. The multiple detection cavities 12 are evenly distributed on the inner rod 11. A detection probe is installed in the middle of the inner wall of the detection cavity 12.

[0035] The pull-out structure includes two guide grooves 16 opened on the flip handle 9. A movable block 15 is slidably arranged in the guide grooves 16. A pull strip 14 is connected to the middle of the side of the movable block 15 near the fixed cylinder 13. The pull strip 14 moves through the flip handle 9. One end of the pull strip 14 is inserted into the fixed cylinder 13 and connected to the inner rod 11. A transmission structure is provided between the movable block 15 and the mounting frame 5.

[0036] The transmission structure includes a rod 17 connected to both ends of the movable block 15. A fan-shaped plate 18 is connected to both sides of each second through slot 7 below the mounting frame 5. A first arc-shaped slot 19 is opened on the fan-shaped plate 18. A connecting slot 20 is opened on the fan-shaped plate 18 to connect one end of the first arc-shaped slot 19. The connecting slot 20 is in the shape of "Z". A second arc-shaped slot 21 is opened on the fan-shaped plate 18. The second arc-shaped slot 21 connects to one end of the connecting slot 20. The diameter of the second arc-shaped slot 21 is 0.6 times the diameter of the first arc-shaped slot 19. One end of the rod 17 is movably inserted into the first arc-shaped slot 19.

[0037] The driving structure includes a driving column 22 that moves through the first through slot 23, a waterproof cylinder 25 installed at the center of the lower part of the first fixed frame 1, a cylinder installed inside the waterproof cylinder 25, and one end of the cylinder output shaft extending out of the waterproof cylinder 25 and connected to the driving column 22. A groove 24 is provided on the side of the driving column 22 near each second through slot 7. A gear 8 is fixedly fitted at the center of each rotating shaft. Teeth are provided on the groove wall of the groove 24 to mesh with the gear 8. During testing, the tilting cylinder 3 is inserted into the water area to be tested. Using the buoyancy of the float plate 4, the device floats on the water surface. Then, the cylinder inside the waterproof cylinder 25 is activated, causing the driving column 22 to move downwards within the first through slot 23 of the mounting frame 5. The teeth in the groove 24 of the driving column 22 drive the gear 8 and the rotating shaft to rotate as a whole, thereby achieving the desired rotation. Opening the flipping cylinder 3 allows multiple flipping cylinders 3 to flip and extend to different areas of the same water body. During the rotation and opening process, the flipping cylinder 3 drives one end of the insertion rod 17 to slide from the first arc-shaped groove 19 and the connecting groove 20 into the second arc-shaped groove 21, thereby driving the moving block 15 to slide in the guide groove 16 of the flipping handle 9. The inner rod 11 is pulled by the pull bar 14 to move closer to the first fixed frame 1 inside the flipping cylinder 3. When the insertion rod 17 slides into the second arc-shaped groove 21, the detection cavity 12 on the inner rod 11 is connected to the detection port 10 on the flipping cylinder 3. In this way, water from the corresponding area enters the detection cavity 12, and the detection probe in the detection cavity 12 performs water quality detection. This enables simultaneous water quality detection in different areas of a certain water body and at different depths.

[0038] See Figures 6-9 The movable structure includes a threaded sleeve 26 sleeved on the fixed cylinder 13. The inner wall of the threaded sleeve 26 and the outer wall of the fixed cylinder 13 are provided with mutually matching threads. The bottom end of the threaded sleeve 26 is fixedly connected to a connecting cylinder 27. The bottom end of the connecting cylinder 27 is fixedly connected to a connecting sleeve 28. The bottom end of the connecting sleeve 28 is rotatably connected to the top end of the flipping cylinder 3.

[0039] The limiting structure includes a limiting strip 29 connected to the bottom of the inner rod 11, and a limiting cylinder 30 connected to the middle of the lower inner wall of the flipping cylinder 3. The bottom end of the limiting strip 29 is movably inserted into the limiting cylinder 30. Both the end faces of the limiting strip 29 and the limiting cylinder 30 are square. When the flipping cylinder 3 rotates in the opposite direction and closes, after the device is pulled out of the water, the threaded sleeve 26 can be rotated on the fixed cylinder 13. The flipping cylinder 3 is driven to move on the fixed cylinder 13 through the connecting cylinder 27. When the detection port 10 on the flipping cylinder 3 moves to the detection chamber 12, the water detected in the detection chamber 12 is directly discharged, which facilitates the next use of the device. When the flipping cylinder 3 moves, the movement of the limiting cylinder 30 on the limiting strip 29 limits the movement of the flipping cylinder 3 on the fixed cylinder 13, so that the movement of the flipping cylinder 3 can smoothly connect the corresponding detection port 10 and the detection chamber 12.

[0040] See Figure 2The buoyancy enhancement structure includes mounting slots on the side of the float plate 4, and each mounting slot is equipped with an airbag 31, with an air nozzle 32 at one end of the airbag 31.

[0041] The adjustment structure includes a lifting sleeve 34 fixed through the middle of the float 4, a screw 33 passing through the lifting sleeve 34, and threads on the inner wall of the lifting sleeve 34. The bottom end of the screw 33 is rotatably connected to the first fixed frame 1, and the screw 33 rotates through the top of the second fixed frame 2 to install a rotating wheel 35. By inflating the air bag 31 through the air nozzle 32, the buoyancy at the float 4 can be increased, preventing the device from sinking directly into the water. In addition, according to the actual depth of the water area to be tested, the rotating wheel 35 can be used to rotate the screw 33, and the lifting sleeve 34 can drive the float 4 to move on the screw 33. By adjusting the distance between the float 4 and the first fixed frame 1, the insertion depth of the tilting cylinder 3 can be flexibly adjusted according to the actual depth of the water area to be tested.

[0042] The implementation principle of a water quality testing device according to an embodiment of the present invention is as follows: First, air is inflated into the airbag 31 through the air nozzle 32, which increases the buoyancy of the float plate 4, preventing the device from sinking directly into the water. Furthermore, depending on the actual depth of the water area to be tested, the screw 33 is rotated by the rotating wheel 35, and the lifting sleeve 34 drives the float plate 4 to move on the screw 33. By adjusting the distance between the float plate 4 and the first fixed frame 1, the insertion depth of the tilting cylinder 3 can be flexibly adjusted according to the actual depth of the water area to be tested. Next, the tilting cylinder 3 is inserted into the water area to be tested, and the buoyancy of the float plate 4 makes the device float on the water surface. Then, the cylinder inside the waterproof cylinder 25 is activated, driving the driving column 22 to move downwards in the first through groove 23 of the mounting frame 5. The teeth in the groove 24 on the driving column 22 drive the gear 8 and the rotating shaft to rotate as a whole. The rotating cylinder 3 is opened, allowing multiple rotating cylinders 3 to rotate and extend to different areas of the same water body. During the rotation and opening process, the rotating cylinder 3 drives one end of the insertion rod 17 to slide from the first arc-shaped groove 19 and the connecting groove 20 into the second arc-shaped groove 21, thereby driving the moving block 15 to slide in the guide groove 16 of the rotating handle 9. The inner rod 11 is pulled by the pull bar 14 to move closer to the first fixed frame 1 inside the rotating cylinder 3. When the insertion rod 17 slides into the second arc-shaped groove 21, the detection cavity 12 on the inner rod 11 is connected to the detection port 10 on the rotating cylinder 3. In this way, water from the corresponding area enters the detection cavity 12, and the detection probe in the detection cavity 12 performs water quality detection. This enables simultaneous water quality detection in different areas of a certain water body and at different depths. When the detection is finished, the rotating cylinder 3 is closed.

[0043] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
