Accurate water quality indicators provide a reliable basis for environmental protection. When the existing water sample sampling device is used, it is necessary to sample water at different depths multiple times, which is time-consuming and laborious and not convenient for operation.

[0003] The prior art CN218725750U discloses a multi-layer water sample sampler for water pollution detection. The top end of a fixing plate is rotatably connected with a lifting mechanism. Connecting plates are arranged at the outer ends of the lifting mechanism and a vertical rod. A multi-layer sampling mechanism is arranged at the bottom end of the connecting plate. A sampling pipe is arranged at the side end of the multi-layer sampling mechanism. A water blocking mechanism is arranged inside the sampling pipe. In the utility model, by putting the multi-layer sampling mechanism into water, then a cross plate floats on the water surface. At this time, rotate a second rotating plate, so that the second rotating plate drives a rotating rod to rotate. At this time, each water blocking plate will open, and water at different depths will enter a first water pollution detection sampling bottle, a second water pollution detection sampling bottle and a third water pollution detection sampling bottle. After sampling, by rotating the second rotating plate, the water blocking plates are closed, and then the whole device is pulled out. At this time, water at different depths can be sampled at one time, without the need for multiple samplings, and it is not time-consuming and laborious, which is convenient for people to operate and use.

[0004] However, in the above technology, the placement stability of the sampler is not enough, and when the multi-layer sampling mechanism is loaded with water samples and the weight increases, it will affect the placement stability of the sampler. Summary of the Utility Model

[0012] Wherein, the adjustment and positioning device further includes a friction pad. The friction pad is fixedly installed at the bottom of the positioning plate and at the bottom of the fixed plate.

[0013] For a water pollution detection sampler of the present utility model, the rotation driving assembly drives the rotating connection block to rotate within the connection seat.

[0025] Among them, the fixed cone 105 penetrates through the positioning plate 104 and is threadedly connected to the positioning plate 104. The handlebar 106 is fixedly connected to the fixed cone 105 and is located at one end of the fixed cone 105. The rotating connection block 107 is fixedly connected to the positioning plate 104 and is located at one end of the positioning plate 104 close to the fixed plate 101. The connecting seat 108 is fixedly connected to the fixed plate 101 and is located at one end of the fixed plate 101 close to the rotating connection block 107. The rotation driving assembly rotatably connects the rotating connection block 107 and the connecting seat 108 and drives the rotating connection block 107 to rotate. The fixed screw hole 114 penetrates through the fixed plate 101 and matches the fixed cone 105.The positioning plate 104 has a cuboid structure, and its width is matched with the width of the fixing plate 101. At both ends of the fixing plate 101, there are multiple fixing screw holes 114 that are the same in number, size and symmetrically arranged. The diameter of the fixing screw holes 114 is matched with the diameter of the fixing cone 105, and the fixing screw holes 114 penetrate through the positioning plate 104, and threads are provided on the inner side thereof, and the threads are matched with the threads on the outer side of the fixing cone 105 to realize the threaded connection between the fixing cone 105 and the positioning plate 104. The number of the fixing cones 105 is two. According to the position where the sampler is placed, the two fixing cones 105 penetrate through the corresponding positions of the positioning plate 104, and the two fixing cones 105 are rotated and inserted into the ground to realize the positioning and fixing work of the positioning plate 104. The turning handles 106 are fixedly provided on the fixing cones 105. The turning handles 106 are circular, and friction strips are provided on the side surfaces thereof to increase the contact friction force, so that it is more labor-saving to rotate the fixing cones 105. The rotating connection block 107 has a cuboid structure with a through hole penetrating transversely. The rotating connection block 107 is fixedly installed at the middle position of the bottom of the positioning plate 104, and the through hole of the rotating connection block 107 is used to connect with the rotating driving assembly. The connecting seat 108 has a U-shaped cross section, and its bottom is fixedly connected to the fixing plate 101, and its open end faces the positioning plate 104, and the length of the U-shaped groove of the connecting seat 108 is matched with the rotating connection block 107. Circular through holes are provided at both ends of the connecting seat 108 for installing the rotating driving assembly. The rotating driving assembly is installed on the connecting seat 108 and connected to the rotating connection block 107 to realize the rotating connection between the rotating connection block 107 and the connecting seat 108, and is used to drive the rotating connection block 107 to rotate with the center of the through hole of the connecting seat 108 as the axis; Therefore, by driving the rotating connection block 107 to rotate in the connecting seat 108 through the rotating driving assembly, the rotation of the rotating connection block 107 drives the fixedly connected positioning plate 104 to rotate until the positioning plate 104 is horizontal relative to the fixing plate 101. Then, the two fixing cones 105 are inserted into the corresponding fixing screw holes 114 and rotated by threads until the tapered bottom of the fixing cone 105 extends into the ground to realize the fixed positioning of the adjusting and positioning device. After the sampling is completed, the two fixing cones 105 are rotated counterclockwise and removed from the ground, and then the positioning plate 104 is driven to rotate to be perpendicular to the fixing plate 101 through the rotating driving assembly, which is convenient for the storage and placement of the sampler. Thus, the sampling fixing stability of the sampler is increased through the adjusting and positioning device, and the sampling error caused by the unstable placement and fixing of the sampler is avoided.

[0026] Secondly, the rotating shaft 109 passes through the rotating connection block 107 and is fixedly connected to the rotating connection block 107, and is rotatably connected to the connection seat 108 through the connection bearing 110; one side of the connection bearing 110 is fixedly connected to the rotating shaft 109, the other side of the connection bearing 110 is fixedly connected to the connection seat 108, and the connection bearing 110 rotatably connects the rotating shaft 109 and the connection seat 108; the rotating handle 111 is fixedly connected to the rotating shaft 109 and is located on one side of the rotating shaft 109. The rotating shaft 109 is of a cylindrical structure, and the diameter of the rotating shaft 109 matches the inner ring diameter of the connection bearing 110, so that both ends of the rotating shaft 109 are fixedly sleeved with the connection bearing 110. Circular through holes are provided at both ends of the connection seat 108, and their diameters match the outer ring diameter of the connection bearing 110 for fixedly installing the connection bearing 110. Thus, the rotating connection between the rotating shaft 109 and the connection seat 108 is realized through the connection bearing 110. The rotating shaft 109 passes through and is fixedly connected to the rotating connection block 107, so that the rotating connection between the rotating connection block 107 and the connection seat 108 is realized through the rotating shaft 109 and the connection bearing 110. The rotating handle 111 is composed of a connecting block with arc-shaped ends and a circular handle and is fixedly installed on the rotating shaft 109. By rotating the handle, the rotating handle 111 drives the rotating shaft 109 to rotate on the connection seat 108 through the connection bearing 110, and the fixedly connected rotating connection block 107 is driven to rotate by the rotation of the rotating shaft 109, thereby realizing the rotational adjustment of the positioning plate 104.

[0027] Meanwhile, the fixing bolt 112 passes through the rotating handle 111 and is threadedly connected to the rotating handle 111; the fastening screw hole 113 passes through the rotating handle 111 and cooperates with the fixing bolt 112. The fixing screw hole 114 is provided at one end of the cylindrical handle of the rotating handle 111 opposite to it and horizontally passes through the rotating handle 111. Threads are provided inside the fixing screw hole 114, and the threads match the threads on the outside of the fixing bolt 112. By screwing the fixing bolt 112 into the fixing screw hole 114 on the rotating handle 111 until the end of the fixing bolt 112 abuts against the connection seat 108, the rotation limitation of the rotating handle 111 is realized, thereby realizing the rotational fixation of the rotating shaft 109 and the rotating connection block 107.

[0028] When using a water pollution detection sampler of the present utility model, the rotation driving assembly drives the rotation connection block 107 to rotate within the connection seat 108. The rotation of the rotation connection block 107 drives the rotation of the fixedly connected positioning plate 104 until the positioning plate 104 is horizontal relative to the fixed plate 101. Then, the two fixed cones 105 are threaded into the corresponding fixed screw holes 114 and rotated. When the conical bottom of the fixed cone 105 extends into the ground, the fixed positioning of the adjustment positioning device is achieved. After sampling is completed, the two fixed cones 105 are rotated counterclockwise to be removed from the ground, and then the rotation driving assembly drives the positioning plate 104 to rotate until it is perpendicular to the fixed plate 101, facilitating the storage and placement of the sampler. Thus, the sampling fixation stability of the sampler is increased through the adjustment positioning device, avoiding sampling errors caused by unstable placement and fixation of the sampler.

[0029] Second Embodiment:

[0030] Please refer to Figure 4 , Figure 4 which is a schematic diagram of the connection structure between the adjustment positioning device and the fixed plate in the second embodiment of the present utility model.

[0031] In this embodiment, the friction pad 215 is fixedly installed at the bottom of the positioning plate 104 and also fixedly installed at the bottom of the fixed plate 101. The number of the friction pads 215 is two, and the shapes of the two friction pads 215 respectively match the bottoms of the fixed plate 101 and the positioning plate 104. The friction pad 215 is made of rubber material. Through the fixed installation of the two friction pads 215, the placement friction between the fixed plate 101 and the positioning plate 104 is increased, making the placement stability of the sampler higher.
