[0002] The Acoustic Doppler Current Profiler (ADCP) is a velocity measurement sonar device developed by integrating multiple disciplines such as underwater acoustic physics, underwater acoustic transducer design, electronic technology, and signal processing. As an application of underwater acoustic technology, Doppler current measurement provides a comprehensive application platform for these related disciplines.

[0003] During use, the ADCP typically needs to be mounted on a fixture, which lowers the ADCP to a velocity measurement location below the water surface to measure the flow velocity there. Existing ADCP fixtures, particularly for fixed-point hydrological measurements on embankments, require a portable fixture bracket that is fixed to the embankment. These brackets are often bulky and difficult to carry. Alternatively, there are pre-installed fixture brackets on the embankment, but when measurements are required at multiple locations, these brackets must be pre-installed at each measurement point, increasing the manpower and material resources required for hydrological measurements. Utility Model Content

[0004] The purpose of the utility model is to provide a portable ADCP flow measurement fixing device, which fixes the flow meter by unfolding the box to ensure the normal operation of the flow meter. The box is closed to form a rectangular parallelepiped, which makes it easy to carry.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0021] See also Figure 1-Figure 3 The present embodiment provides a portable ADCP flow measurement and fixing device, comprising a box body 1 and a fixing plate 2. The box body 1 is in a rectangular shape and includes a left side plate 11, a right side plate 12, an upper side plate 13, and three side plate units 14 located at the front, lower, and rear side positions of the box body 1. The left side plate 11 and the right side plate 12 are fixedly connected by a bottom plate 15. The left and right sides of the rear end of the upper side plate 13 are hinged to the left side plate 11 and the right side plate 12 respectively. The upper side plate 13 and the three side plate units 14 are hinged end to end in sequence. The fixing plate 2 is arranged between the left side plate 11 and the right side plate 12 and is used to fix the flow meter 3.

[0022] When the present invention is in use, the box body 1 is unfolded so that the upper side panel 13 and the three side panel units 14 are connected in a vertical shape, thereby exposing the flow meter 3 in the box body 1, and a vertical connecting bracket is formed by the upper side panel 13 and the three side panel units 14, so that the side panel unit 14 at the upper end can be installed and fixed on the river bank, and the side panel unit 14 and the upper side panel 13 are leaned against the vertical surface or inclined surface of the river bank, and at the same time, the flow meter 3 at the lower end is placed in the water to realize water velocity measurement; when the present invention is not in use, the upper side panel 13 and the three side panel units 14 are rotated and closed to form a rectangular box body 1 on the outside of the flow meter 3, thereby reducing the volume of the present invention and improving the portability of the present invention.

[0023] Therefore, the present invention fixes the flow meter 3 by unfolding the box body 1 to ensure the normal operation of the flow meter 3. The box body 1 is folded into a rectangular parallelepiped to facilitate the carrying of the present invention. At the same time, it can avoid the installation of multiple fixing brackets when measuring multiple points, reducing the manpower and material resources consumed in hydrological measurement.

[0024] In the present invention, the flow meter 3 can be always installed on the fixing plate 2 , avoiding the need to repeatedly install and disassemble the flow meter 3 each time it is used. The box body 1 can also protect the flow meter 3 .

[0025] See also Figure 2The side panel unit 14 includes an upper slide 16 and a lower slide 17, which are connected to each other for sliding up and down. The upper slides 16 and lower slides 17 in adjacent side panel units 14 are hingedly connected, and the lower slide 17 in the side panel unit 14 located on the front side of the box body 1 is hingedly connected to the upper side panel 13.

[0026] When the present invention is used for a river bank with a low water level or for measuring the water velocity at a location with a greater water depth, the length of the side plate unit 14 is increased by sliding and unfolding the upper slide plate 16 and the lower slide plate 17 in the side plate unit 14, thereby increasing the distance between the uppermost end of the utility model after unfolding and the flow meter 3. This allows the flow meter 3 to be extended downward to a lower position while the uppermost end of the utility model is fixed on the river bank, thereby completing the measurement of the water velocity at a lower water level or a location with a greater water depth.

[0027] See also Figure 2 The lower slide plate 17 is penetrated by a hand-tightening bolt 4 , which is threadedly connected to the lower slide plate 17 , and the inner end of the hand-tightening bolt 4 is against the upper slide plate 16 .

[0028] After adjusting the relative position between the upper slide 16 and the lower slide 17 and adjusting the length of the side plate unit 14, the hand-tightening bolt 4 is tightened to make its inner end rest on the upper slide 16, thereby locking the relative position of the upper slide 16 and the lower slide 17, that is, locking the length of the side plate unit 14, making it easy to adjust the position of the flow meter 3 into the water and realize the measurement of water velocity at multiple water depths.

[0029] See also Figure 2 、 Figure 3 The upper ends of the left side plate 11 and the right side plate 12 are hingedly provided with support rods 5, and the upper ends of the support rods 5 are hinged on the upper side plate 13. The support rods 5 include hinged rods 51 that are hingedly connected, and the hinges of the two support rods 5 are provided with sleeves 52 through threaded connection sleeves.

[0030] The support rod 5 improves the stability of the connection between the left side panel 11, the right side panel 12 and the upper side panel 13, and reduces the degree of shaking of the flow meter 3 when the water speed is too high, and even reduces the risk of the left side panel 11 and the right side panel 12 falling off the upper side panel 13. When the utility model is closed to form a rectangular box body 1, the rotating sleeve 52 is moved away from the hinge position of the two hinged rods 51, and the two hinged rods 51 can be rotated and stacked and stored between the upper side panel 13 and the left side panel 11 and the right side panel 12; when the utility model is unfolded and working normally, the two hinged rods 51 can be unfolded into a straight line, and then the sleeve 52 is rotated to move the sleeve 52 to the hinge position of the two hinged rods 51. The sleeve 52 restricts the rotation of the two hinged rods 51, thereby realizing the support function of the support rod 5 on the left side panel 11, the right side panel 12 and the upper side panel 13.

[0031] See also Figure 2 A plurality of slide rails 18 are provided on the inner sides of the left side plate 11 and the right side plate 12 , and the fixed plate 2 is provided on the slide rails 18 so as to slide up and down.

[0032] When the present invention is in normal use, the fixing plate 2 is moved downward so that the flow meter 3 extends downward through the opening on the bottom plate 15 to the bottom of the left plate 11 and the right plate 12, thereby reducing the obstruction of the left plate 11 and the right plate 12 to the water flow, which causes a large error in the test data of the flow meter 3; when not in use, the fixing plate 2 is moved upward so that the flow meter 3 returns to between the left plate 11 and the right plate 12, so as to facilitate the storage of the flow meter 3 in the box body 1.

[0033] See also Figure 1 A handle 6 is provided on the outer side surface of the upper side plate 13, which facilitates the transportation of the box body 1 and improves the portability of the utility model.

[0034] See also Figure 1 The side panel unit 14 at the rear side of the box body 1 is fixedly connected to the left side panel 11 and the right side panel 12 by means of hand-tightening bolts 4, thereby fixing the shape of the box body 1 and preventing the box body 1 from falling apart when not in use. The use of hand-tightening bolts 4 facilitates the rapid expansion and closure of the box body 1.

[0035] See also Figure 2 The side panel unit 14 located at the rear side of the box body 1 is fixed with an L-shaped mounting bracket 7 by bolts.

[0036] The mounting frame 7 facilitates the fixing of the present invention on a river bank at a right angle, thereby improving the convenience of fixing the present invention on the river bank.

[0037] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
