Description

Technical Field

[0001] This utility model relates to the technical field of water body detection, and more specifically, to a fixed water body detection device. Background Technology

[0002] Water quality sampling and testing refers to collecting water samples from polluted water bodies and analyzing them to obtain basic data on water pollution. The water samples used for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, and frequency are all determined based on the characteristics of the water body and the purpose of the analysis.

[0003] There are various methods for water quality testing, such as collecting samples and sending them to a testing laboratory, or conducting in-situ testing directly at the water source. For water sources with large testing volumes, high testing frequency, and inconvenient sampling, the latter is more suitable. This method involves installing the testing device at a fixed point in the water, inserting the probe into the corresponding location. This allows for both periodic testing and real-time data reading. However, such a device can only test the water quality at one point and one depth. For large-scale water quality testing requiring multiple points and depths, a large number of detectors would need to be deployed, which is not only cumbersome to operate but also very costly.

Detailed Implementation

[0020] Example

[0021] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 3 As shown, the fixed water body detection device of this embodiment includes a vertically arranged mounting plate 10, a pair of first slide rails 15 vertically arranged on one side of the mounting plate 10, a horizontally arranged detection tube 11 slidably connected to the pair of first slide rails 15, a detection head 13 disposed in the detection tube 11, a wire 14 connected to the detection head 13, a detector connected to the wire 14, and a driving device for driving the detection tube 11 to rise and fall; the mounting plate 10 is disposed in the water, and the detector is disposed above the water surface. Specifically, in use, the mounting plate 10 is installed in the water where long-term water body monitoring is required, and the detector is fixed above the water surface. When water flows through the detection tube 11, the detection head 13 in the detection tube 11 can detect the water body. By driving the detection tube 11 to rise and fall through the driving device, the water quality of water bodies at different depths can be detected, and more effective data can be collected. Furthermore, by installing the detection head 13 in the detection tube 11, it is possible to prevent garbage, aquatic plants, etc. in the water body from covering the detection head 13 and affecting its detection function.

[0022] In this embodiment, the detection tube 11 has a pair of first sliders 12 on its side wall, and one of the first sliders 12 is slidably connected to one of the first slide rails 15. Specifically, this not only ensures that the detection tube 11 moves stably in the vertical direction, but also allows for a certain distance between the detection tube 11 and the mounting plate 10, reducing the impact of the mounting plate 10 on the water flow around the detection tube 11.

[0023] In this embodiment, the axial direction of the detection tube 11 is parallel to the water flow direction. Specifically, this allows for more timely flow and renewal of water in the detection tube 11, enabling more accurate detection of water quality at different depths.

[0024] In this embodiment, multiple sealing devices 20 are also provided at both ends of the detection tube 11. The sealing devices 20 are used to seal the detection tube 11; the multiple sealing devices 20 are distributed vertically. Specifically, the function of the sealing devices 20 is to block both ends of the detection tube 11, and then the detector detects the water body, thus improving the static water detection effect. The sealing devices 20 can be pre-fixed at the depth of the water body to be detected. When the detection tube 11 moves to the sealing device 20, the water in the detection tube 11 is then detected. Therefore, the position of the sealing devices 20 can be adjusted as needed.

[0025] The sealing device 20 in this embodiment includes a horizontally arranged sleeve 21, a plugging ball 22 disposed at one end of the sleeve 21 near the detection tube 11, and a spring 23 for connecting the sleeve 21 and the plugging ball 22; the minimum distance between the pair of plugging balls 22 is less than the length of the detection tube 11; the diameter of the plugging ball 22 is greater than the outer diameter of the detection tube 11; the sleeve 21 is connected to the side wall of the mounting plate 10. Specifically, during the up-and-down movement of the detection tube 11, when the detection tube 11 moves to the sealing device 20, since the distance between the pair of plugging balls 22 is less than the length of the detection tube 11, the detection tube 11 will first push the pair of plugging balls 22 apart, continue to move upward, and then the pair of plugging balls 22 will be stuck at both ends of the detection tube 11, thereby sealing the detection tube 11. At this time, the water in the detection tube 11 can be detected. After the detection is completed, the driving device is used to continue to pull the detection tube 11 upward, and the plugging ball 22 will naturally detach from the detection tube 11.

[0026] In this embodiment, a sliding rod 24 is slidably provided inside the sleeve 21. One end of the sliding rod 24, located outside the sleeve 21, is fixedly connected to the ball stopper 22. A push-button switch 25 is provided at the end of the sleeve 21 away from the ball stopper 22. The sliding rod 24 is used to trigger the push-button switch 25, which is connected to the drive device. Specifically, the sliding rod 24 serves two purposes: first, to make the movement of the ball stopper 22 more stable and linear; second, when the detection tube 11 pushes the ball stopper 22, it also pushes the sliding rod 24 toward the push-button switch 25, thereby triggering the push-button switch 25 and transmitting a signal to the drive device, causing the drive device to temporarily stop operating. After a set time interval, the drive device resumes operation, thus achieving better automation.

[0027] The sealing device 20 in this embodiment further includes a second slide rail 27 vertically arranged and connected to the mounting plate 10, and a second slider 26 fixedly connected to the side wall of the sleeve 21. The second slider 26 is fixedly connected to the second slide rail 27. Specifically, the position of the second slider 26 on the second slide rail 27 can be adjusted as needed to detect water quality at different depths.

[0028] In this embodiment, the upper side of the detection tube 11 is connected to an air guide pipe 16, and the lower side of the detection tube 11 is provided with a drain pipe 17. The drain pipe 17 is equipped with a one-way valve, and the air guide pipe 16 is connected to an air compressor. The air compressor is located above the water surface. Specifically, when the detection cycle is long and the water pollution is severe, air can be slowly introduced into the detection tube 11 through the air compressor, and the water in the detection tube 11 can be discharged through the drain pipe 17, so that the detection head 13 is not immersed in sewage for a long time, thus better protecting the detection head 13. When the water pollution is more severe and has a certain degree of corrosiveness, the air compressor can be replaced with a water pump, using clean water as the water source. Clean water can be slowly pumped into the detection tube 11 through the air guide pipe 16 to dilute and discharge the sewage, so that the water in the detection tube 11 has minimal corrosive effect on the detection head 13. The reason for slowly introducing air or water is to avoid the sudden entry of air or water into the detection tube 11 and pushing open the blocking ball 22.

[0029] The driving device in this embodiment includes a motor, a winding roller disposed on the output shaft of the motor, and a pull rope 18 wound on the winding roller; the pull rope 18 is fixedly connected to the upper middle part of the detection tube 11, and both the motor and the winding roller are disposed above the water surface.

[0030] In summary, the fixed water body detection device of this embodiment is used by installing the mounting plate 10 in the water where long-term monitoring of the water body is required, fixing the detector above the water surface, and when the water flows through the detection tube 11, the detection head 13 in the detection tube 11 can detect the water body. By driving the detection tube 11 to rise and fall through the drive device, the water quality of water bodies at different depths can be detected, and more effective data can be collected. Furthermore, by installing the detection head 13 in the detection tube 11, it is possible to prevent garbage, aquatic plants, etc. in the water body from covering the detection head 13 and affecting the detection function of the detection head 13.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
