[0006] Furthermore, a housing is provided above the crossbeam, the motor is installed in the housing, the rotatable column is vertically arranged between the crossbeam and the base, and the motor shaft passes through the crossbeam and is connected to the top plate of the rotatable column so that the motor can drive the rotatable column to rotate.

[0007] Furthermore, the rotatable column has a circular groove inside, and the base has a column that mates with the circular groove.

[0008] The base is equipped with a housing, and the motor is fixed in the housing. The motor shaft is connected to the bottom plate of the rotatable column, so that the motor can drive the rotatable column to rotate. The crossbeam is equipped with a limiting shaft, and the limiting shaft is rotatably connected to the top plate of the rotatable column.

[0009] Furthermore, the rotatable column is a rectangular column, and the side that fixes the variable track is provided with multiple screw holes.

The traction rope is detachably connected to the mounting bracket. One end of the hose is connected to the horizontal support. A canopy and solar panels are provided above the second column.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] This utility model discloses a rotating structure for an underwater ultrasonic flow meter transducer system mounting bracket. It includes a first column with a convertible structure. The variable track above water and the underwater section are separate parts. The track above water is fixed to the rotatable column of the first column. The column is driven by a motor to rotate the track 90° or another angle suitable for convenient maintenance, allowing for repair and replacement. This ensures the mounting base faces outwards from the channel. After replacement, the track is rotated back and aligned with the fixed track below, allowing the mounting bracket to be repositioned underwater. This solves the problem of inconvenient maintenance and replacement when the mounting bracket is raised above the water and faces the channel surface. Attached Figure Description

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1 to 4 As shown, the rotating structure of the mounting bracket for an underwater ultrasonic flowmeter transducer system of this utility model includes a rotatable column 602, on which a variable track 9 is fixed. A fixed track 8 is provided on the channel 1. The variable track 9 is aligned with and cooperates with the fixed track 8 so that the mounting bracket 2 can move along the fixed track 8 to the variable track 9. The rotatable column 602 can rotate the variable track 9 and the mounting bracket 2 moved to the variable track 9 by a predetermined angle, so that the mounting bracket 2 faces an angle that is convenient for replacement and installation. The mounting bracket 2 includes a mounting base plate, which is a whole plate. The mounting base plate is drilled to form mounting holes. The transducer 3 and pipe clamps are fixed to the whole plate with bolts. The PVC pipe 4 is fixed with pipe clamps. An installation groove is provided on the channel 1. The installation groove can be a T-shaped groove. The bottom of the installation groove is provided with a base plate, which can be supported by a triangular support frame. The mounting bracket 2, transducer 3, and PVC pipe 4 are integrated and placed in the installation groove. The top of the installation groove can be fixed with bolts by a sealing plate to restrict the overall structure. A first column 6 and a second column 7 are installed on channel 1. The first column 6 includes a base 601 fixed to channel 1 by anchor bolts and a rotatable column 602 connected to the base 601. One side of the rotatable column 602 is provided with a variable track 9, and a fixed track 8 is provided in the mounting groove. When the transducer 3 needs to be repaired, the baffle is removed, and the mounting bracket 2 together with the transducer 3 and other integral structures are moved from below the water surface to the variable track 9. The rotatable column 602 is rotated 90° to perform repair and replacement. After completion, the rotatable column 602 is rotated back and the integral structure is placed back below the water surface.

[0022] In the above embodiments, reference is made to Figure 1 As shown, the first column 6 also includes a support rod 603, on which a crossbeam 604 is connected. (Refer to...) Figure 3 As shown, in specific embodiment 1, a chassis is provided above the crossbeam 604, and the motor 605 is installed in the chassis. The rotatable column 602 is vertically arranged between the crossbeam 604 and the base 601. The rotating shaft of the motor 605 passes through the crossbeam 604 and is connected to the top plate of the rotatable column 602, so that the motor 605 can drive the rotatable column 602 to rotate. The lower surface of the rotatable column 602 is provided with an inwardly extending circular groove 606. The base 601 is provided with a column that mates with the circular groove 606. The base 601 is provided with a control cabinet, which can control the motor 605 to drive the rotatable column 602 to rotate. (Refer to...) Figure 4 As shown, in specific embodiment 2, a housing is provided inside the base 601, and the motor 605 is fixed in the housing. The rotating shaft of the motor 605 is connected to the bottom plate of the rotatable column 602, enabling the motor 605 to drive the rotatable column 602 to rotate. A limiting shaft is provided on the crossbeam 604, and the limiting shaft is rotatably connected to the top plate of the rotatable column 602. In embodiments 1 and 2 above, the rotating shaft of the motor 605 and the limiting shaft can be connected to the rotatable column 602 by a key, or they can be fixed.

[0023] In the above embodiments 1 and 2, referring to Figure 1 As shown, it also includes a second column 7, which is equipped with a drive system for lifting and lowering the mounting bracket 2, such as an electric winch driven by a motor 605. A horizontal support 701 is set on the second column 7, and a fixed pulley is set on the horizontal support 701. The traction rope of the winch is vertically connected to the mounting bracket 2 through the fixed pulley. A lifting ring can be welded on the mounting bracket 2, and the end of the traction rope can be connected to a hook rope. A canopy can be provided above the second column 7 for rain protection, and a solar panel can provide power.

[0024] In the above embodiments 1 and 2, referring to Figure 2 As shown, the rotatable column 602 has a rectangular or square cross-section, and the side that fixes the variable track 9 has multiple screw holes 607. The mounting bracket 2 has corresponding holes, so that when the mounting bracket 2 moves onto the variable track 9, it can be fixed to the rotatable column 602 with bolts. The detachable connection between the traction rope and the mounting bracket 2, and the fixing of the mounting bracket 2 to the rotatable column 602, can prevent the traction rope from twisting and generating torsional force during rotation, and avoid the mounting bracket 2 from becoming unstable under the force generated by the torsion of the traction rope.

[0025] In the above embodiments 1 and 2, referring to Figure 1As shown, a PVC pipe 4 is fixed on the mounting bracket 2. A flexible hose, including a corrugated hose 5, is connected to the upper end of the PVC pipe 4. The PVC pipe 4 needs to provide waterproofing and protection for the transducer 3 cable. However, a rigid or semi-rigid PVC pipe 4 cannot meet the requirements of the liftable mounting bracket 2. Lifting is achieved by replacing a portion above the water surface with a flexible hose, while the portion below the water surface still uses the PVC pipe 4. The flexible hose is prone to elastic deformation under the impact of water flow, making it difficult to meet the waterproofing requirements of the cable joint portion underwater.
