DETAILED DESCRIPTION

[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0019] A drainage pipe positioning mechanism comprises: a bracket 1 with a multi-edge structure, a clamping assembly 2 fixed correspondingly at the center of each edge of the bracket 1, and an extrusion wheel 3, wherein the clamping assembly 2 comprises at least three groups and each central axis intersects at the center of the bracket 1, each of the clamping assemblies 2 comprises an adjusting block 4, a positioning shaft 5, a first fixing nut 6, and a second fixing nut 7, the adjusting block 4 is sleeved on the edge of the bracket 1 and is spaced from the edge of the bracket 1 in the axial direction thereof, the positioning shaft 5 is coaxial with the adjusting block 4 and is arranged through the edge of the bracket 1, the first fixing nut 6 is used for threadingly fixing the positioning shaft 5 and the bracket 1, an adjusting hole 8 is also opened on the side of the adjusting block 4, the second fixing nut 7 is arranged through the adjusting hole 8 and is threadedly fixed to the bracket 1, and the extrusion wheel 3 comprises a plurality of and one-to-one corresponding rotationally connected to the inner side of each clamping assembly 2.

[0020] The bracket 1 includes a triangular arm 9 and a bow arm 10, the triangular arm 9 is fixed with the clamping assembly 2, the upper and lower sides of the bow arm 10 are respectively fixed with the clamping assembly 2, one end of the triangular arm 9 is hinged to one end of the bow arm 10, and the other end is fixed with bolts to the other end of the bow arm 10 through a fixing rod 11.

[0021] The distance between the adjusting block 4 and the edge of the bracket 1 is not less than the length of the adjusting hole 8. A fixing block 12 is also fixed to the outside of the middle part of the arched arm 10. One end of the fixing block 12 is bolted to the arched arm 10, and the other end is exposed to the bracket 1 and a connecting rod 13 is bolted to the exposed part. A plum blossom ring 14 is also fixed to the top of the positioning shaft 5. The extrusion wheel 3 is a combined type, and the bottom surface of the adjusting block 4 is exposed. The adjusting block 4 is concave with an oblique opening 14 at the rotation connection corresponding to the extrusion wheel 3.

[0022] Through the above structure, in the actual water body survey operation process, the pipe used for drainage and export of water samples can be positioned by the positioning structure of the utility model. The specific positioning process is as follows: first, keep the bow arm 10 and the triangular arm 9 fixed at one end open, then pass the pipe through the middle, and then fix it through the fixing rod 11 to form a bracket 1 structure, and then adjust each clamping component 2 accordingly to ensure that the clamping wheel can squeeze and contact the pipe. During the adjustment process, depending on the interval between the adjustment block 4 and the edge of the bracket 1, after the second fixing nut 7 and the first fixing nut 6 are loosened, the adjustment block 4 can be dragged back and forth at the interval, correspondingly realizing The three clamping wheels are relatively far away or close to each other. After ensuring that the clamping wheels can fit tightly on the surface of the pipe to form an extruded and fixed structure, the second fixing nut 7 and the first fixing nut 6 are locked in sequence. The design of the positioning shaft 5 not only connects the bracket 1, but also can limit the adjustment range of the adjustment block 4 at the interval. Similarly, in actual application, it can be fixed on equipment such as the hull and survey vehicles. Therefore, the utility model also has a fixing block 12 fixed on the outside of the middle part of the bow arm 10. The fixing block 12 and the connecting rod 13 can easily position the positioning structure at any point of the external equipment to avoid shaking of the pipeline during water sampling.

[0023] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
