[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a water body sampling device for water environment protection, the water body sampling device for water environment protection comprises a sampling barrel 1, a water storage chamber 11 opened inside the sampling barrel 1, a traction rope 2 installed on the top of the sampling barrel 1 for driving the sampling barrel 1, a filter 3 is installed inside the sampling barrel 1, and a disassembly part 4 is installed at the bottom of the filter 3 and inside the sampling barrel 1;

[0029] The filter element 3 includes a filter bucket 31 installed inside the sampling barrel 1, a filter plate 32 is installed on the surface of the filter bucket 31, filter holes 33 are provided on the surfaces of the filter bucket 31 and the filter plate 32, and the filter holes 33 are arranged in a ring array. A mounting groove 34 is provided inside the filter bucket 31, and a sealing groove 35 is provided at the bottom of the filter bucket 31 and at the bottom of the mounting groove 34. A sealing strip 36 is installed inside the sampling barrel 1, and the sealing strip 36 is located inside the sealing groove 35. The setting of the sealing strip 36 and the sealing groove 35 can prevent impurities from flowing into the water storage chamber 11 through the mounting groove 34. The interior of the filter bucket 31, that is, the bottom of the filter plate 32 is hollowed out, which can facilitate the filtered water to flow into the water storage chamber 11.

[0030] The filter plate 32 is set in a conical shape, and the installation groove 34 is set in a rounded rectangular shape. The conical filter plate 32 can make the filtering efficiency of the sampling barrel 1 higher, reduce the filtering residue, and thus improve the performance of the sampler. The installation groove 34 can facilitate the installation and disassembly of the filter bucket 31 and the sampling barrel 1.

[0031] The disassembly part 4 includes a rotating rod 41 installed inside the sampling barrel 1. The surface of the rotating rod 41 is provided with an external thread 42. The rotating rod 41 is threadedly connected to the sampling barrel 1 through the external thread 42, which can make the rotating rod 41 self-locking and prevent the rotating rod 41 from rotating due to water flow.

[0032] A positioning plate 44 is fixedly connected to the top of the rotating rod 41. The positioning plate 44 is located on the surface inside the filter bucket 31. The top of the rotating rod 41 extends to the surface of the filter bucket 31 through the mounting groove 34 and is fixedly connected to the positioning plate 44. The positioning plate 44 is set in a rounded rectangle. The positioning plate 44 and the mounting groove 34 are set vertically to position the filter bucket 31. When the positioning plate 44 and the mounting groove 34 coincide with each other, the filter bucket 31 can be disassembled, so as to achieve the purpose of facilitating the quick disassembly and installation of the filter bucket 31.

[0033] A knob 45 is fixedly connected to the top of the positioning plate 44 , and a rubber strip 46 is installed on the outer surface of the knob 45 . The rubber strip 46 is arranged in a ring array to increase the friction between the operator's hand and facilitate the driving of the rotating rod 41 and the positioning plate 44 to rotate.

[0034] A cavity 47 is provided inside the sampling barrel 1, and a retaining ring 43 is fixedly connected to the bottom of the rotating rod 41. The retaining ring 43 is located inside the cavity 47 and is movably connected to the cavity 47. The bottom of the rotating rod 41 extends to the bottom of the cavity 47 and is fixedly connected to the retaining ring 43. The diameter of the retaining ring 43 is larger than that of the rotating rod 41, which can limit the rotating rod 41 to prevent the rotating rod 41 from being separated from the sampling barrel 1 due to excessive rotation, thereby ensuring the stability of the rotating rod 41.

[0035] A counterweight 5 is installed at the bottom of the sampling barrel 1. The counterweight 5 is hexagonal in shape, which can concentrate the weight at the bottom of the sampling barrel 1 to improve the stability of the sampling barrel 1 and avoid shaking and tilting during the sampling process. The hexagonal counterweight 5 can reduce the damping of the sampling barrel 1 by the water flow, improve the penetration of the sampling barrel 1 when it enters the water, and make the sampling faster and more efficient.

[0036] A water outlet pipe 6 is installed on one side of the sampling barrel 1, one end of which is connected to the water storage chamber 11, and a valve 61 is installed on the top of the water outlet pipe 6. The valve 61 is used to control whether water flows from the inside of the water storage chamber 11, which can facilitate the detection operation.

[0037] During use, the sampling bucket 1 is slowly placed in the water body through the traction rope 2. Due to the setting of the counterweight 5, the sampling bucket 1 can be moved vertically into the water body. During this process, the water body will slowly flow into the interior of the filter bucket 31. Due to the setting of the filter bucket 31 and the conical filter plate 32, the water body will slowly flow into the water storage chamber 11 through the filter hole 33, and some impurities with a slightly larger volume such as fallen leaves will remain on the surface of the filter plate 32 and the filter bucket 31. When the sampling is completed, the sampling bucket 1 is slowly pulled straight to the shore through the traction rope 2, so that impurities with a slightly larger volume such as fallen leaves can be filtered to prevent them from affecting the accuracy and representativeness of the test;

[0038] Then, the knob 45 can be directly turned to drive the rotating rod 41 to rotate along the inside of the sampling barrel 1 through the external thread 42 and slowly rise, so that the retaining ring 43 rises inside the cavity 47 until the direction of the positioning plate 44 is consistent with the installation groove 34, and the filter bucket 31 can be directly removed, and the intercepted fallen leaves and other slightly larger impurities can be cleaned up, so that the purpose of quickly cleaning the intercepted impurities can be achieved. During installation, the operation is reversed, which further facilitates the cleaning operation of the staff;

[0039] Subsequently, when testing the sampled water, place the measuring cup on one side of the water outlet pipe 6, and start the valve 61 to allow the water inside the water storage chamber 11 to slowly flow out to the measuring cup on the side of the water outlet pipe 6 for testing. In this way, the water sampling operation for water environment protection can be completed, further facilitating the testing operation of the water body.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
