[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The embodiments of the utility model will be described according to the overall structure of the utility model.

[0033] Embodiment one:

[0034] A bottom-mounted Doppler current profiler, such as Figures 1-4 As shown, the device includes a base 1 and a Doppler current profiler body 2. A pull plate 4 is fixed to one side of the base 1. The pull plate 4 is arrow-shaped and inclined. Ribs 5 are fixed inside the pull plate 4. Multiple ribs 5 are equidistantly distributed. A support plate 6 is fixed to the other side of the base 1. The support plate 6 has an inverted "V" shaped cross-section and a groove 7 on its top. A first anti-bending plate 8 is fixed between the support plate 6 and the base 1. A second anti-bending plate 9 is fixed between the support plate 6 and the pull plate 4. Multiple second anti-bending plates 9 are equidistantly distributed. The base 1, pull plate 4, ribs 5, support plate 6, first anti-bending plate 8, and second anti-bending plate 9 are all made of stainless steel. When the river water flow is fast, the pull plate 4 presses against the base 1... A tensile force is applied in front, and the rib plate 5 reduces the force on the head end of the arrow of the pull plate 4, preventing it from opening, deforming, or even breaking. The support plate 6 extends the length of the base 1 and supports it from behind. It pulls in front and supports from behind, increases the contact area with the ground, reduces the bending of the anchor rod 3 due to radial force, and the interior of the groove 7 can hold heavy objects such as sand and gravel, further improving stability. The first anti-bending plate 8 and the second anti-bending plate 9 form reinforcement, reducing the upward bending deformation of the pull plate 4 and the support plate 6, which weakens the support of the base 1. This effectively reduces the phenomenon of displacement of the base 1 and upward tilting of the water-facing surface caused by water flow impact, thereby improving stability. At the same time, the support frame 11 supports the back of the Doppler current profiler body 2, reducing the displacement of the Doppler current profiler body 2 caused by water flow impact.

[0035] See Figures 1-4 In the above embodiment, four anchor rods 3 are fixed on both sides of the bottom of the base 1. The four anchor rods 3 are distributed in a rectangular array. The bottom of the pull plate 4 and the support plate 6 are buried in the riverbed and the base 1 is fixed to the riverbed by the anchor rods 3. Then the flow velocity of the river can be detected by the Doppler current profiler body 2.

[0036] Example 2:

[0037] Based on the above embodiment 1, in order to reduce the direct burial of the Doppler current profiler body 2 by sand and gravel accumulation, the following settings are now adopted.

[0038] See Figures 1-4 In the above embodiment, the base 1 is fixedly equipped with an extension frame 10. The extension frame 10 increases the height of the Doppler current profiler body 2, reducing the impact of underground sand and gravel accumulation on the Doppler current profiler body 2 being buried and affecting detection. A support frame 11 is fixed to the top of the extension frame 10, and the Doppler current profiler body 2 is installed inside the support frame 11. Both the extension frame 10 and the support frame 11 are made of stainless steel. The support frame 11 supports the back of the Doppler current profiler body 2, reducing the displacement of the Doppler current profiler body 2 caused by water flow impact.

[0039] The implementation principle of the utility model is: first, the pull plate 4 and the support plate 6 bottom are buried in the river bottom landfill and through the anchor rod 3 and the base 1 are fixed in the river bottom, after that, the river flow velocity can be detected through the doppler flow velocity profiler main body 2, and the height of the doppler flow velocity profiler main body 2 is increased through the setting of the height increasing frame 10, and the river channel underground sandstone accumulation directly buries the doppler flow velocity profiler main body 2 and influences detection.

[0040] When the river water flow velocity is fast, the pull plate 4 is applied to the front of the base 1, and the rib plate 5 reduces the stress of the head end of the pull plate 4 arrow to open deformation or even break, and the support plate 6 extends the length of the base 1 and supports behind the base 1, and the front pull and the rear support increase the ground contact area, reduce the bending of the anchor rod 3 affected by the radial force, and the inside of the groove 7 can contain sandstone and other heavy objects, further improve the stability, and the first bending resistance plate 8 and the second bending resistance plate 9 form reinforcement, reduce the upward bending deformation of the pull plate 4 and the support plate 6, weaken the support of the base 1, effectively reduce the phenomenon of the base 1 displacement and the water surface upward, and further improve the stability; at the same time, the support frame 11 supports the back of the doppler flow velocity profiler main body 2, reduces the displacement of the doppler flow velocity profiler main body 2 caused by the water flow impact.

[0041] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the interpretation of the utility model, and are not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiment without creative contribution after reading the specification without departing from the principle and purpose of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
