Description

Technical Field

[0001] This utility model relates to a transducer assembly that is easy to adjust. Background Technology

[0002] The transducers are installed in the river to perform ultrasonic velocimetry, obtain the cross-sectional flow rate of the river water, and realize the hydrological monitoring of the river. For this purpose, it is necessary to pair the transducers.

[0003] Therefore, it is necessary to adjust the angle of the transducer at different water levels according to the slope and water level, and then fix it.

[0004] During use, due to changes in flow rate, temperature, and geological subsidence, the initially installed transducer may become active or require fine-tuning as needed. Therefore, the transducer must have at least two degrees of freedom to ensure flexible adjustment.

[0005] In addition, since the traditional adjustment process does not provide data on the degrees of freedom for angle adjustment, secondary adjustments are time-consuming and laborious.

[0006] Therefore, how to facilitate secondary adjustments during use and ensure that the transducer does not become loose or shifted during use has become an urgent technical problem to be solved. Utility Model Content

[0007] In general, the technical problem to be solved by this utility model is to provide a transducer assembly that is easy to adjust.

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows: To enable transducer angle adjustment and fixation, a conveniently adjustable transducer assembly includes a base; an intermediate frame is provided on the base; and a transducer is provided in the intermediate frame. A pressure cap for the pressure transducer is installed on the intermediate frame; The transducer has curved sections on both sides; The base and the middle frame are connected and fixed by side bolts.

[0009] As a further improvement to the above technical solution: To enable data transmission, the front of the transducer is the probe section, and the back is connected to the data cable.

[0010] For ease of adjustment, the inner wall of the pressure cap and intermediate frame has arc-shaped sidewalls corresponding to the two sides of the transducer; To facilitate installation, fixation, and transducer adjustment, the base and / or intermediate frame are U-shaped.

[0011] To achieve fixation and prevent the transducer from swinging, serrated areas are provided on both ends of the middle frame. Two elastic pins are provided on both sides of the base, and the elastic pins are used to connect with the scoring area.

[0012] The base has coaxial side through holes A and side through holes B on both sides. To achieve the connection, on the intermediate frame, Side through hole A corresponds to side screw hole A; Side through hole B corresponds to side screw hole B.

[0013] To facilitate angle determination and adjustment, thereby enabling visualization and facilitating later maintenance, a scale A is coaxially provided on the outer ring of the side through hole A. A top through hole and a top scale are coaxially arranged on the gland; a top hexagonal hole is provided on the top of the transducer; A scale piece is provided in the hexagonal hole at the top, with its upper end protruding from the top through hole; the scale piece has a hexagonal plug; An indicator scale is obliquely set on the hexagonal plug; The indicator scale corresponds to the top dial.

[0014] The side bolt components include side bolt component A and side bolt B; Side bolt A and side bolt B correspond to side screw holes A and B, respectively.

[0015] The side bolt has a central through hole A; Similarly, to facilitate angle determination, a hexagonal positioning inner hole is provided inside the through hole A; The hexagonal positioning inner hole is used to correspond to the hexagonal plug of the scale piece that is inserted from the side; The scale piece protrudes from the side through-hole A, indicating that the scale corresponds to the top scale A; To compensate for the transducer gap and improve the support friction, side adjustment pads are installed on the inner side wall of the intermediate frame. Lateral screw hole B is designed to be transparent; Side bolt B has a head B; a side pressure washer B is provided at the end of the head B; Side pressure pad B is used for the corresponding outer wall of the side pressure transducer.

[0016] To facilitate the determination of the starting reference, a side reference mark is provided on the top of one end of the base; A side movable alignment line is set at the top of the corresponding end of the intermediate frame; When the side reference mark is aligned with the side movable alignment line, the sway angle of the intermediate frame is zero.

[0017] A top fixing line is provided on the gland; The transducer is equipped with a corresponding top movable pair line; When the top fixed line is aligned with the top movable line, the transducer rotation angle is zero.

[0018] This invention avoids slight transducer misalignment during use, ensuring a secure fixation. It also prevents inconvenience caused by inconsistencies between installers and maintainers, as it utilizes spacers for elastic compression to address the misalignment caused by changes in transducer gap due to water temperature fluctuations. This utility model is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use.

[0025] like Figure 1-5 As shown, the easily adjustable transducer assembly of this embodiment includes a base 1 that can be fixed on the river slope; an intermediate frame 2 is provided on the base 1 to achieve intermediate transition connection; and a transducer 4 is provided in the intermediate frame 2 to achieve transducer yaw and rotation adjustment.

[0026] A pressure cap 3 for the pressure transducer 4 is installed on the intermediate frame 2 to achieve pressure fixation.

[0027] The transducer 4 has arc-shaped sections on both sides, and the inner walls of the cover 3 and the intermediate frame 2 have arc-shaped side walls corresponding to the two sides of the transducer 4. This allows for the rotational swing angle, while the curved surface provides a limit to prevent the transducer from escaping. The base 1 and the intermediate frame 2 are connected and fixed by side bolts 5, which serve as a fixed connection and hinge pivot.

[0028] As a standard structure, the front of the transducer 4 is the probe section, and the back is connected to the data cable.

[0029] The base 1 and / or the intermediate frame 2 have a U-shaped structure, which facilitates connection and angle adjustment.

[0030] As an extended protection, it has scoring areas 6 on both ends of the middle frame 2; Two elastic pins 7 are provided on both ends of the base 1. The elastic pins 7 are used to connect with the scoring area 6.

[0031] Friction is increased by scoring, and the transducer is prevented from wobbling on its own by using at least two top pins on one side.

[0032] The base 1 has coaxial side through holes A8 and side through holes B10 on both sides respectively; On the intermediate frame 2 Side through hole A8 corresponds to side screw hole A9; The side through hole B10 corresponds to the side screw hole B28, thereby achieving threaded connection and fixation.

[0033] A scale A11 is coaxially provided on the outer ring of the side through hole A8; A top through hole 18 and a top scale 19 are coaxially provided on the pressure cover 3; a top hexagonal hole 22 is provided on the top of the transducer 4; A scale piece 13 with its upper end exposed in the top through hole 18 is provided in the top hexagonal hole 22; the scale piece 13 has a hexagonal plug 14; An indicator scale 15 is obliquely set on the hexagonal plug 14; The indicator scale 15 corresponds to the top dial 19. It uses a simple scale to visualize the yaw angle, which is simple and convenient.

[0034] As one of the improvements, the side bolt component 5 includes side bolt component A and side bolt B25; This invention uses side bolt A to achieve lateral pulling and fixing of the intermediate frame 2, while its hollow inner cavity facilitates the insertion of the hexagonal plug. Side bolt B25 achieves lateral compression of the transducer to prevent shaking, and the use of a pad for lateral pressure also solves the over-positioning problem, achieving lateral compression fixing.

[0035] Side bolt A and side bolt B25 correspond to side screw holes A9 and B28, respectively.

[0036] Side bolt component 5 has a central through hole A23; A hexagonal positioning inner hole 24 is provided inside the through hole A23; The hexagonal positioning inner hole 24 is used to correspond to the hexagonal plug 14 of the scale piece 13 inserted from the side; Similarly, the scale piece 13 protrudes from the side through hole A8, and the indicator scale 15 corresponds to the top scale A11; A side adjustment pad 17 is provided on the inner side wall corresponding to the intermediate frame 2; The side screw hole B28 is designed to be transparent; The side bolt B25 has a top head B26; a side pressure pad B27 is provided at the end of the top head B26, thereby realizing the lateral position adjustment of the transducer and avoiding lateral displacement. Side pressure pad B27 is used for the corresponding outer wall of side pressure transducer 4.

[0037] A side reference mark 12 is provided on the top of one end of the base 1; A side movable alignment line 16 is provided at the top of the corresponding end of the intermediate frame 2; When the side reference mark 12 is aligned with the side movable alignment line 16, the sway angle of the intermediate frame 2 is zero.

[0038] A top fixing line 20 is provided on the pressure cap 3; A corresponding top movable pair line 21 is provided on the transducer 4; When the top fixed line 20 is aligned with the top movable line 21, the rotation angle of the transducer 4 is zero.

[0039] During initial installation, the reference scale lines are aligned with the zero scale line as a reference, enabling yaw / rotation angle adjustment during angle adjustment.

[0040] In operation, this invention allows the base 1 to be fixed on a slope, connecting to the intermediate frame. On side B, after inserting the side bolt B25 into the lateral screw hole B28, the side pressure pad B27 is installed using bolts. Preferably, on side A, the side adjustment pad 17 is installed using adhesive, compression, or bolts. The transducer 4 is then placed, and the pressure cover 3 is added. The intermediate frame 2 is tilted and fixed using the notched area 6 and elastic pins 7. Zero-degree alignment is achieved through the side reference notch 12, the side movable alignment line 16, the top fixed line 20, and the top movable alignment line 21. Then, the corresponding scale piece 13 is inserted, aligning the indicating scale 15 with the zero-degree mark on its side of the dial, and it is fixed using rivets. The transducer and / or the intermediate frame are rotated and tilted according to the desired preferred angle. At the same time, the angle is recorded visually. Due to the hexagonal design, synchronous oscillation is achieved, which facilitates direct maintenance by maintenance personnel without having to contact the installation personnel, thereby saving costs and shortening time.
