[0025] Step 1: In the initial state, the fixed frame, the connecting frame and the flip frame are placed side by side in the rectangular gap, and the floating plate is placed on the water surface. Under the driving action of the servo motor, the motor shaft of the servo motor drives the lead screw to rotate synchronously, and under the action of the thread of the lead screw and the threaded sleeve, the threaded sleeve, the connecting plate and the three fixed ear seats are driven to slide downward along the fixed slide rod;

[0028] Step 4. After the flip frame is in a horizontal state, the detection end on it extends into the water, directly contacts the water body through the detection end and detects the water body.

[0030] 1. In the present invention, the detection end is driven to translate outward by the use of a connecting rod mechanism, so that the detection can cover a wider area of ​​water. By translating outward, water samples at different locations can be detected. For some large lakes or harbors, different water areas can be divided and areas with possible pollution gradient changes can be effectively monitored, which greatly increases the detectable range.

[0031] 2. In the present invention, the detection terminal can be turned downward and extended into the water by the use of the flipping mechanism, which increases the flexibility of the angle of entry of the detection terminal into the water; compared with the traditional fixed-angle entry method, it can flexibly adjust the entry angle according to the actual situation of the water body, and through the appropriate flipping angle, the detection terminal can smoothly enter the water of a suitable depth for detection, reducing the impact and interference of the water flow on the detection terminal, and improving the stability of the detection equipment and the accuracy of the detection data;

[0032] In summary, the present invention can flexibly control the position and angle of the detection end in water through the cooperation of the connecting rod mechanism and the flipping mechanism. The translation and flipping actions can be accurately operated according to pre-set coordinates or detection requirements, thereby improving the accuracy of water environment detection.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] Embodiment 1: This embodiment provides a water environment detection auxiliary device, see Figure 1-8 , comprising a floating plate 1, the top surface of which is provided with three evenly distributed rectangular notches, each of which is provided with a vertically distributed fixed frame 2, and a three-claw bracket 11 is provided between the top ends of the three fixed frames 2;

[0045] The outer side of the fixed frame 2 is provided with a parallel connection frame 3, and the fixed frame 2 is connected to the corresponding connection frame 3 through a connecting rod mechanism. The outer side of the connection frame 3 is provided with a vertically distributed flip frame 4, and the connection frame 3 is connected to the corresponding flip frame 4 through a flip mechanism;

[0046] A pair of detection modules 41 are fixedly arranged on both sides of the bottom surface of the flip frame 4. Under each detection module 41, there are parallel elliptical connecting plates 42. A spherical rod-shaped detection terminal 43 is inserted in the middle of the bottom surface of each elliptical connecting plate 42. The detection terminal 43 directly contacts the water body and detects the water body. The detection terminal 43 converts the physical and chemical signals detected in the water environment into electrical signals and transmits them to the detection module 41. The detection module 41 then transmits the data to the monitoring center in real time, so that the monitoring personnel can timely understand the dynamic changes of water quality.

[0047] The detection terminal 43 is electrically connected to the detection module 41 by wire. A pair of buffer springs are fixed on both sides of the bottom surface of the detection module 41, and the bottom ends of the pair of buffer springs are fixed to both sides of the top surface of the elliptical connecting plate 42 respectively.

[0048] In water environment testing, it may be necessary to move the equipment to different locations according to the needs of the testing task, such as from a testing point in a lake to another testing point in a river. By folding and storing, the equipment can be easily carried. Whether it is transported by vehicle or manually, small-volume equipment has more advantages.

[0049] Moreover, in some special water environment detection scenarios, such as in narrow rivers or shallow areas, the folded and stored equipment can be more easily placed in a suitable position and then unfolded for detection, which enhances the maneuverability of the equipment in complex environments.

[0050] Embodiment 2: Based on Embodiment 1, this embodiment also includes the following contents:

[0051] In the specific implementation process, Figure 5 and Figure 6 As shown, the connecting rod mechanism includes a first connecting rod 23, a second connecting rod 24, a fourth connecting rod 26, and a fifth connecting rod 27. A fixed shaft 21 is rotatably inserted at the top of the fixed frame 2, and the first connecting rod 23 is fixed on the fixed shaft 21.

[0052] A first connecting shaft is fixedly inserted at the top of the connecting frame 3, and a fourth connecting rod 26 is hingedly provided on the first connecting shaft. A second connecting shaft is fixedly inserted at the bottom of the connecting frame 3, and a fifth connecting rod 27 is hingedly provided on the second connecting shaft.

[0053] The first connecting rod 23 and the fifth connecting rod 27 are arranged in parallel, and the second connecting rod 24 and the fourth connecting rod 26 are arranged in parallel; the bottom end of the first connecting rod 23 and the bottom end of the fourth connecting rod 26 are movably hinged, and the top end of the second connecting rod 24 and the top end of the fifth connecting rod 27 are movably hinged; under the hinged action of the first connecting rod 23 and the fourth connecting rod 26, and under the hinged action of the second connecting rod 24 and the fifth connecting rod 27, the connecting frame 3 can be driven to translate in a direction away from the fixed frame 2;

A coaxially hinged third link 25 is provided at the hinged joint of the first link 23 and the fourth link 26, and the middle part of the third link 25 is movably hinged to the middle part of the fifth link 27. A first U-shaped notch is provided at the top end of the third link 25, and the opening of the first U-shaped notch is slidably engaged with the limit pin 32. In cooperation with the parallel hinged action of the hinged link 28 and the third link 25, the limit pin 32 and a pair of rectangular sliders 31 can be driven to slide downward along the limit slide groove under the limiting action formed by the first U-shaped notch and the limit pin 32.

[0056] When the connecting rod mechanism drives the connecting frame 3 to move outward away from the fixed frame 2, the operating range of the water environment detection can be significantly expanded. The outward movement can enable the detection probe 43 to cover a wider area of ​​water. By moving outward, just like stretching a person's arm, it can reach a farther water surface area. For large-area water body detection, such as lakes, large reservoirs, etc., more comprehensive water quality information can be obtained.

[0057] Embodiment 3: Based on Embodiment 2, this embodiment also includes the following contents:
