In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0023] Reference Figures 1 to 7 In an embodiment of the utility model, an environmental pollutant collection sampler includes: a sampler body 1 and a handle 6, a telescopic mechanism 2 is arranged at one end inside the sampler body 1, a limiting mechanism 3 is arranged at one end inside the sampler body 1, a connecting seat 4 is arranged at one end below the telescopic mechanism 2, and a sampling tube 5 is screwed at one end below the connecting seat 4.

[0024] The telescopic mechanism 2 includes a connecting block 21 fixedly connected to one end of the sampler body 1, a main shaft 22 is rotatably connected to one end of the connecting block 21, a first bevel gear 23 is fixedly connected to one end of the side of the main shaft 22, a rotating disk 24 is fixedly connected to one end of the side of the main shaft 22, a rotating handle 25 is fixedly connected to one end of the side of the rotating disk 24, a second bevel gear 26 is rotatably connected to one end of the sampler body 1, a threaded rod 27 is fixedly connected to one end below the second bevel gear 26, and a connecting column 28 is screwed to one end below the threaded rod 27.

[0025] The above scheme is adopted: rotating the handle 25 drives the main shaft 22 to rotate, thereby driving the first bevel gear 23 fixed to the side to rotate, the first bevel gear 23 drives the second bevel gear 26 meshing below to rotate, thereby driving the threaded rod 27 fixed below the second bevel gear 26 to rotate, pushing the connecting column 28 screwed below to rotate and thus descend.

[0026] The limiting mechanism 3 comprises a fixing plate 31 fixedly connected to one end of the side of the sampler body 1 , a reset mechanism 32 is arranged at one end of the side of the fixing plate 31 , and a limiting block 33 is arranged at one end of the side of the reset mechanism 32 .

[0027] The reset mechanism 32 includes a telescopic rod 321 fixedly connected to one end of the side of the fixed plate 31, and a spring 322 is sleeved on one end of the side of the telescopic rod 321. The limit block 33 includes a limit block body 331 fixedly connected to one end of the side of the telescopic rod 321, and a connecting frame 332 is fixedly connected to one end of the side of the limit block body 331.

[0028] Adopting the above scheme: when the sampling tube 5 reaches the middle of the sampler body 1, the limit block 33 will block the connection seat 4 from rising and limit it, so that the sampling tube 5 and the connection seat 4 stay in the middle of the sampler body 1 to prevent the sewage sample from leaking. When the limit needs to be cancelled, the connection frame 332 can be pulled toward the outside of the device to move the limit block body 331 backward.

[0029] The connecting seat 4 includes a connecting seat body 41 fixedly connected to one end below the telescopic mechanism 2 . A fixing ring 42 matched with the sampling tube 5 is provided at one end below the connecting seat body 41 .

[0030] A through hole is formed at one end of the side surface of the fixing plate 31 for the connecting frame 332 to slide.

[0031] A cavity for accommodating a limiting mechanism 3 and a sampling tube 5 is provided at one end of the sampler body 1 .

[0032] The working principle of the utility model is as follows: first, the rotating handle 25 is rotated to drive the main shaft 22 to rotate, thereby driving the first bevel gear 23 fixed to the side to rotate, and the first bevel gear 23 drives the second bevel gear 26 meshing below to rotate, thereby driving the threaded rod 27 fixed below the second bevel gear 26 to rotate, pushing the connecting column 28 screwed below to rotate and thus descend, thereby driving the connecting seat 4 and the sampling tube 5 below to descend, and when the connecting seat 4 leaks out from the bottom of the sampler body 1, the rotation is stopped, and then the sampling tube 5 and the connecting seat 4 are placed in the sewage to be sampled by the carrying handle 6. In the water, sewage will flow into the sampling tube 5 below through the water inlet hole opened on the side of the connecting seat 4. After the sampling is completed, the rotating handle 25 is turned in the opposite direction to raise it. When the sampling tube 5 reaches the middle of the sampler body 1, the limit block 33 will block the connection seat 4 from rising and limit it, so that the sampling tube 5 and the connecting seat 4 stay in the middle of the sampler body 1 to prevent the sewage sample from leaking. When the limit needs to be cancelled, the connection frame 332 can be pulled toward the outside of the device to move the limit block body 331 backward, thereby canceling the limit. The sampling tube 5 can be removed from the connecting seat 4 by twisting it, and the sampling is completed at this time.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
