[0031] Figure 1And Figure 2 The water body detection water taking device shown in the figure comprises a water taking bucket 1, a handle 2 is rotationally arranged on the surface of the water taking bucket 1, and an auxiliary device 3 is arranged on the surface of the water taking bucket 1, wherein the auxiliary device 3 ensures the safety of the water sample in the water taking bucket 1 by means of a filter cover 31 and a protective cover 37, and a stabilizing device 4 is arranged at the bottom position of the water taking bucket 1.

[0032] Figure 1 、 Figure 2 And Figure 3 The auxiliary device 3 shown in the figure comprises a filter cover 31, wherein a plurality of holes are formed in the surface of the filter cover 31, two mounting plates 32 are mounted on the surface of the filter cover 31, wherein the mounting plates 32 are connected and fixed with the surface of the water taking bucket 1 by means of bolts 33, a servo motor 34 is mounted on the surface of the filter cover 31, wherein the output end of the servo motor 34 is mounted with a threaded rod 35 by means of a shaft coupling, the threaded rod 35 is threadedly connected with a mounting rod 38 on the arc surface of the threaded rod, wherein the two ends of the mounting rod 38 are fixedly connected with the protective cover 37, two positioning plates 36 are slidingly arranged on the surface of the mounting rod 38, wherein the positioning plates 36 are connected and fixed with the surface of the filter cover 31, when the water taking bucket 1 is used to collect the water sample, first, the rope is connected and fixed with the handle 2 on the surface of the water taking bucket 1, then the rope is stretched to lower the water taking bucket 1 into the sampling water area, after diving to the sampling depth, the servo motor 34 on the surface of the protective cover 37, the operation of the servo motor 34 drives the rotation of the threaded rod 35 on the output end thereof, because the mounting rod 38 on the threaded rod 35 is limited by the positioning plates 36 fixedly connected on the protective cover 37, so the mounting rod 38 is lifted under the driving of the threaded rod 35, thereby separating the protective cover 37 from the filter cover 31, so that the water enters the water taking bucket 1 from the holes of the filter cover 31 and the impurities are intercepted, after the sampling is completed, the servo motor 34 is started again to make the protective cover 37 rewrap on the surface of the filter cover 31, so that the inner cavity of the water taking bucket 1 forms a sealed state, and the rope is retracted to lift the water taking bucket 1, when the sampling device is used to collect the water sample, the reliability of the water sample is better ensured, the water sample is not easy to be mixed with other water layers, the subsequent use can be better, and the use effect and functionality of the water taking device are improved.

[0033] Figure 1 、 Figure 2 And Figure 3The auxiliary device 3 also includes a sealing ring 39 installed on the arc surface of the protective cover 37. The sealing ring 39 improves the protective effect of the protective cover 37. The rubber sealing ring 39 allows the protective cover 37 to fit more closely to the surface of the filter cover 31, making it less likely to have gaps, thus ensuring the sealing of the water bucket 1 before and after water intake. The auxiliary device 3 also includes a protective sleeve 310 fitted on the arc surface of the threaded rod 35. The protective sleeve 310 is fixedly connected to the surface of the servo motor 34. The protective sleeve 310 prevents impurities and foreign objects from entering the gaps at the output end when the servo motor 34 drives the screw to rotate. The auxiliary device 3 also includes a positioning block 311 installed on the inner wall of one end of the positioning plate 36. The positioning block 311 ensures the stable connection between the positioning plate 36 and the mounting rod 38. The positioning block 311 prevents the mounting rod 38 from detaching when sliding in the inner wall of the positioning plate 36, thus ensuring the stable lifting and lowering of the protective cover 37.

[0034] Figure 1 and Figure 4 The stabilizing device 4 shown includes a counterweight 41, on the surface of which several evenly distributed fixing plates 42 are fixedly connected. The fixing plates 42 are connected and fixed to the bottom of the water collection bucket 1 by means of screws 43. Before the water collection bucket 1 is lowered into the water for sampling, the counterweight 41 is attached to the bottom of the water collection bucket 1. At this time, the fixing plates 42 fixedly connected to the surface of the counterweight 41 will contact the bottom of the water collection bucket 1. Then, the screws 43 are connected to the surface of the fixing plates 42, and the screws 43 are threaded to the surface of the water collection bucket 1. At this time, the water collection bucket 1 can be better stabilized when it is lowered into the water with the help of a rope, and it is not easy to shake. Therefore, when collecting water samples, the accuracy of the sampling depth is better guaranteed.

[0035] Figure 1 and Figure 4 The stabilizing device 4 shown also includes a knob 44 mounted on the surface of the screw 43. The knob 44 assists in the operation of the screw 43. The setting of the knob 44 makes it easier and faster to rotate the screw 43 during use, thereby making the assembly of the counterweight 41 more convenient. The stabilizing device 4 also includes a protective shell 45 on the surface of the counterweight 41. The protective shell 45 improves the stability of the counterweight 41 on the water bucket 1. The setting of the protective shell 45 further reduces the water resistance when the water bucket 1 is submerged in water, and can better break the water drop, thereby better ensuring the stability of the water bucket 1.

[0036] Working principle: When collecting water samples using the water collection bucket 1, first connect and fix the rope to the handle 2 on the surface of the water collection bucket 1. Then, stretch the rope to lower the water collection bucket 1 into the sampling area. After reaching the sampling depth, the servo motor 34 on the surface of the protective cover 37 will rotate, causing the threaded rod 35 on its output end to rotate. Because the mounting rod 38 on the threaded rod 35 is limited by the positioning plate 36 fixedly connected to the protective cover 37, the mounting rod 38 rises under the action of the threaded rod 35, thereby driving the protective cover 37 to rotate. The separation of the protective cover 37 from the filter cover 31 allows water to enter the water collection bucket 1 through the holes in the filter cover 31, while intercepting impurities. After sampling is completed, the servo motor 34 is restarted to allow the protective cover 37 to re-cover the surface of the filter cover 31, forming a sealed state inside the water collection bucket 1. The rope is then retracted to extract the water bucket 1. At this time, when using the sampling equipment to collect water samples, the reliability of the water samples is better guaranteed, and they are less likely to be mixed with water samples from other water layers. This allows for better subsequent use and improves the effectiveness and functionality of the water collection device.

[0037] Before the water sample is taken from the water collection bucket 1, the counterweight 41 is attached to the bottom of the water collection bucket 1. At this time, the fixing plate 42 fixedly connected to the surface of the counterweight 41 will contact the bottom of the water collection bucket 1. Then, the screw 43 is connected to the surface of the fixing plate 42, and the screw 43 is threaded to the surface of the water collection bucket 1. This way, when the water collection bucket 1 is lowered into the water with the help of the rope, it can maintain stability better and is less prone to shaking. This ensures the accuracy of the sampling depth when collecting water samples.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
