[0028] refer to Figure 1 to Figure 2According to a preferred embodiment of the utility model, a collection device for collecting water samples at different depths is provided. It should be noted that the collection device for collecting water samples at different depths includes a shell 10 and a first cover 20. The shell 10 has a first opening 101, a cavity 102 and a second opening 103. The first opening 101 and the second opening 103 are both connected to the cavity 102, and the first opening 101 and the second opening 103 are also connected to the outside. In addition, the first cover 20 is threadedly connected to one end of the shell 10 where the second opening 103 is provided, thereby closing the second opening 103.

[0029] It should be noted that the outer wall of the shell 10 also has a first connecting hole 104 and a second connecting hole 105. The first connecting hole 104 and the second connecting hole 105 are arranged opposite to each other and are separated by a predetermined distance. The first connecting hole 104 is also located on the upper side of the second connecting hole 105. The first connecting hole 104 and the second connecting hole 105 are both connected to the cavity 102.

[0030] It should also be noted that the collection device for collecting water samples at different depths also includes a sampling assembly 30, which is movably arranged in the cavity 102. Specifically, the sampling assembly 30 includes a handle 31, and the handle 31 has an insertion portion 311 and a gripping portion 312. The gripping portion 312 is connected to the insertion portion 311, and the gripping portion 312 is placed outside. The insertion portion 311 passes through the first opening 101 and is placed in the cavity 102. In addition, the sampling assembly 30 also includes a sampling shell 32, which is movably arranged in the cavity 102, and the end of the insertion portion 311 placed in the cavity 102 is fixedly connected to the top of the sampling shell 32.

[0031] Furthermore, the sampling shell 32 has a third connecting hole 3201, a receiving cavity and a fourth connecting hole 3202. The third connecting hole 3201 and the fourth connecting hole 3202 are both connected to the receiving cavity, and the third connecting hole 3201 is opposite to the first connecting hole 104 and is connected to the first connecting hole 104. It should also be noted that the third connecting hole 3201 and the fourth connecting hole 3202 are arranged opposite to each other and are separated by a predetermined distance. It is worth mentioning that the bottom of the sampling shell 32 also has a third opening, and the third opening is also connected to the receiving cavity, and the fourth connecting hole 3202 is close to the third opening. In addition, Figure 2As shown, the side wall forming the storage cavity also has a first annular protrusion 321, and the first annular protrusion 321 is located between the third connecting hole 3201 and the fourth connecting hole 3202. It is worth mentioning that the first annular protrusion 321 is integrally formed with the sampling shell 32, and the sampling assembly 30 also includes a second cover 33, and the second cover 33 is threadedly connected to the end of the sampling shell 32 provided with the third opening, so as to close the third opening. In addition, the sampling assembly 30 also includes a partition 34, and the partition 34 is fixedly connected to the side of the first annular protrusion 321 close to the third opening, preferably welded, so as to divide the storage cavity into a first sampling cavity 3203 and a second sampling cavity 3204, and the third connecting hole 3201 is opposite to the first sampling cavity 3203, and the fourth connecting hole 3202 is opposite to the second sampling cavity 3204.

[0032] It should be understood by those skilled in the art that when the housing 10 is placed in water, water can pass through the first connecting hole 104 and the third connecting hole 3201 in sequence and be placed in the first sampling cavity 3203. In addition, in order to prevent water from flowing out from the gap between the wall surface forming the cavity 102 and the outer wall of the sampling housing 32, a sealing ring 200 is further provided on the outer wall of the sampling housing 32, and the sealing ring 200 is also close to the second cover 33, thereby preventing water from flowing to the first cover 20. In addition, when the sampling shell 32 has finished sampling, the user can push the sampling shell 32 toward the first cover body 20 through the handle, and at this time the first connecting hole 104 will be misaligned with the third connecting hole 3201. In order to prevent water from flowing to the top of the sampling shell 32 when the first connecting hole 104 is misaligned with the third connecting hole 3201, a sleeve 35 is further provided on the top of the sampling shell 32. The sleeve 35 is also sleeved on the insertion portion 311 of the handle 31, and the outer wall of the insertion portion 311 also has a second annular protrusion 3111, and the top of the sleeve 35 also abuts against the second annular protrusion 3111, that is, when the sampling shell 32 moves downward a predetermined distance, the sleeve 35 will block the first connecting hole 104, and the sleeve 35 can be implemented as a rubber part.

[0033] In order to prevent the sampling shell 32 from deflecting during movement, the wall surface forming the cavity 102 is further provided with at least two guide blocks 1021, the two guide blocks 1021 are arranged opposite to each other and spaced apart by a predetermined distance, and the outer wall of the sampling shell 32 is further provided with at least two guide grooves, and both ends of the two guide grooves are connected to the cavity 102, and the two guide grooves are respectively matched with the two guide blocks 1021, so as to limit the moving direction of the sampling shell 32.

[0034] It should be noted that the center of the first cover body 20 also has a drainage hole 201, and the drainage hole 201 also penetrates the first cover body 20, and those skilled in the art should understand that when the shell 10 is inserted into water, water will enter the cavity 102 through the second connecting hole 105 and the drainage hole 201, and then when the user presses the grip 312, the water in the cavity 102 will be discharged through the second connecting hole 105 and the drainage hole 201 until the second cover body 33 contacts the second cover body 33, at which time the second connecting hole 105 is opposite to the fourth connecting hole 3202, and at this time the water passes through the second connecting hole 105 and the fourth connecting hole 3202 in turn and enters the second sampling cavity 3204.

[0035] It should also be noted that the collection device that is convenient for collecting water samples at different depths also includes a limiting sleeve 36 and a rotating sleeve 37, the rotating sleeve 37 has a resting end 371 and an extension end 372, and the resting end 371 is connected to the extension end 372, and the rotating sleeve 37 has a first assembly hole, the first assembly hole passes through the resting end 371 and the extension end 372 in sequence, and the first assembly hole is threadedly connected to the insertion portion 311, so that the user can limit the position of the resting end 371 by rotating the rotating sleeve 37, and the resting end 371 is located in the cavity 102, and the end of the extension end 372 facing away from the resting end 371 is placed outside. The limiting sleeve 36 has a second matching hole, the extension end 372 is movably connected to the second matching hole, and the abutting end 371 contacts the bottom of the limiting sleeve 36. In addition, the outer portion of the limiting sleeve 36 is fixedly connected to the side wall forming the cavity 102, preferably welded or threaded. That is, when the sampling of the second sampling cavity 3204 is completed, the user can manually rotate the rotating sleeve 37 to make the rotating sleeve move the abutting end 371 upward by a predetermined distance. At this time, when the gripping portion 312 is pulled, the sampling shell 32 will move upward by a predetermined distance. At this time, the second sampling cavity 3204 is closed, and when the abutting end 371 contacts the bottom of the limiting portion, since the abutting end 371 is raised by a predetermined height before, the first communication hole 104 and the third communication are misaligned, so the first sampling cavity 3203 is closed, thereby ensuring that external factors will not interfere with the sample, so as to ensure the reliability of sampling.
