The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figures 1 to 3 As shown, the utility model provides an integrated ultrasonic open channel flow metering mechanism;

[0031] The solar panel support frame 13 is a U-shaped structure, and the flip adjustment screw 14 passes through both sides of the solar panel support frame 13 and is threadedly connected to the solar panel 11; by twisting the flip adjustment screw 14 forward and backward, the connection tightness between the solar panel support frame 13 and the solar panel 11 can be adjusted to achieve the pitch angle adjustment of the solar panel 11;

[0032] A plurality of arc-shaped through grooves 133 arranged in a ring shape are provided on the bottom of the solar panel support frame 13. A plurality of internally threaded recesses 32 sunk along the inner cavity of the flow meter 1 are constructed on the cover shell 31 of the flow meter 1, that is, the inner cavity of the recess 32 is designed as an internal thread, and the rotary adjustment screw 15 passes through the arc-shaped through groove 133 and is threadedly connected with the internally threaded recess 32. In this embodiment, four groups of arc-shaped through grooves 133 are provided, and the four groups of arc-shaped through grooves 133 are arranged in a ring shape, and four groups of rotary adjustment screws 15 are provided accordingly; the connection tightness between the solar panel support frame 13 and the flow meter 1 is adjusted by rotating the rotary adjustment screw 15 forward and backward to achieve the rotation angle adjustment of the solar panel 11;

[0033] Through the above design, the solar panel 11 can realize both pitch angle adjustment and rotation angle adjustment, so as to cope with different actual installation conditions.

[0034] The rotary adjustment screw 15 is also provided with a gasket 19, one end of which abuts against the nut of the rotary adjustment screw 15, and the other end of which abuts against the solar panel support frame 13 outside the arc-shaped through groove 133;

[0035] The gasket 19 plays the role of anti-slip and increasing the force-bearing surface; on the one hand, it has a larger contact area than the nut of the screw 15, which can increase the damping and avoid slipping during rotation. On the other hand, it can increase the force-bearing area and prevent the nut with a smaller contact surface from directly pressing against the outside of the arc-shaped groove 133, causing deformation of the arc-shaped groove 133.

[0036] A plurality of flip adjustment threaded holes 111 corresponding to the flip adjustment screws 14 are provided on both side ends of the solar panel 11, and the plurality of flip adjustment threaded holes 111 are arranged along the height direction of the solar panel 11; the height position of the solar panel 11 is adjusted by threading the flip adjustment screws 14 to connect the flip adjustment threaded holes 111 at different height positions, so as to cope with different actual installation conditions.

[0037] like Figures 4 to 5As shown, further, the metering mechanism also includes a ladder frame 12, and the ladder frame 12 includes a main ladder 121 of an isosceles trapezoidal structure and an extension ladder 122 of a strip structure; the flow meter 1 is fixed on the main ladder 121, and the solar panel support frame 13, the flow meter 1, and the ladder frame 12 are integrated into a design, so that the structure of the mechanism is compact, and the installation of the flow meter 1 and the solar panel 11 can be completed at the same time by setting up the ladder frame 12, and the two ends of the main ladder 121 and the extension ladder 122 are fixedly connected by a perforated channel steel 16 and a locking screw 17, one end of one extension ladder 122 is used to abut the slope wall of the channel body, and one end of the other extension ladder 122 is used to abut the bottom of the channel body. Through the design that the two extension ladders 122 respectively abut the slope wall and the bottom of the channel body, the solar panel 11 is erected above the channel body, and when the metering point needs to be replaced, the main ladder and the extension ladder are separated by twisting the locking screw, and they are assembled and erected after reaching the metering point.

[0038] A measuring through hole 123 is provided at a position of the main ladder 121 corresponding to the probe of the flow meter 1 , so as to provide an installation space for the probe of the flow meter 1 .

[0039] The bottom of the extension ladder 122 is configured with a fixing ear 18 , which is connected to the slope wall of the channel body after passing through the ear hole of the fixing ear 18 through an anchor screw, thereby improving the connection stability of the ladder frame 12 .

[0040] Furthermore, the present application also discloses a sensor 2 used in correspondence with the metering mechanism;

[0041] like Figures 6 to 8 As shown, the sensor 2 is mounted on the sensor carrier 21, and the sensor carrier 21 is embedded in the shock absorbing rubber seat 22 of the shock absorbing rubber seat group. Both ends of the sensor carrier 21 extend to the outside of the shock absorbing rubber seat 22. The width of the shock absorbing rubber seat 22 corresponds to the width of the inner wall of the protective concave platform 4. The protective concave platform 4 is a concrete structure, which is masonry-bonded to the slope wall and the bottom of the canal body, thereby avoiding digging a fixed weir groove on the slope wall and the bottom of the canal body to install the sensor 2, thereby avoiding structural damage to the canal body; through the shock absorbing rubber seat The design of 22 can play a buffering and energy release role when it hits the inner wall of the protective recess 4 during installation, thereby preventing the sensor 2 on the sensor carrier 21 from being displaced due to impact. The two ends of the sensor carrier 21 extend to the outside of the shock-absorbing rubber seat 22 to clamp the limiting ears 23. The two groups of limiting ears 23 are clamped at the two ends of the shock-absorbing rubber seat 22, and the long screws 27 penetrate the through holes on the fixing plates 26 on both sides of the bottom of the limiting ears 23, thereby realizing the fixation of the sensor carrier 21 on the channel body.

[0042] The shock-absorbing rubber seat group also includes a limiting ear 23, which is a square cylindrical structure. A slot 231 corresponding to the wall thickness of the sensor carrier 21 is constructed on the open end of the limiting ear 23. The two groups of limiting ears 23 are designed to face each other and are clamped with the two ends of the sensor carrier 21 through the slot 231.

[0043] Specifically, the sensor carrier 21 is a U-shaped structure, and a cover plate 24 is clamped at the open end of the sensor carrier 21. The cover plate 24 is provided with a limiting groove 25 adapted to the sensor 2; the sensor 2 is mounted in the sensor carrier 21 and plugged into the limiting groove 25, thereby achieving the same angle orientation of several sensors 2, which facilitates the alignment of the sensors 2 on the slope wall and the bottom of the channel body.

[0044] Specifically, through holes are opened on the two side walls of the sensor carrier 21 at positions corresponding to the limiting grooves 25 , and the sensor fixing screws 41 pass through the through holes and are threadedly connected to the sensors 2 , thereby fixing the sensors 2 on the sensor carrier 21 .

[0045] Specifically, the limiting ear 23 is installed on the fixing plate 26. Since the shock-absorbing rubber seat 22 has a certain thickness, the fixing plate 26 plays a role in raising the limiting ear 23, so that the limiting ear 23 and the sensor carrier 21 are in the same horizontal plane.

[0046] The working principle and working process of the utility model are as follows:

[0047] By turning the adjusting screw 14 forward and backward, the connection tightness between the solar panel support frame 13 and the solar panel 11 can be adjusted to achieve the pitch angle adjustment of the solar panel 11;

[0048] By rotating the adjusting screw 15 forward and backward, the tightness of the connection between the solar panel support frame 13 and the flow meter 1 can be adjusted to achieve the rotation angle adjustment of the solar panel 11;

[0049] When installing the flow meter 1 and the solar panel 11, the main ladder 12 and the extension ladder 122 are tightly connected to each other by twisting the locking screws, and then one end of one of the extension ladders 122 abuts against the slope wall of the channel body, and one end of the other extension ladder 122 abuts against the bottom of the channel body. The two extension ladders 122 are designed to abut the slope wall and the bottom of the channel body respectively, and then the anchor screws are passed through the ear holes of the fixing ears 18 and then connected to the slope wall of the channel body, so that the flow meter 1 and the solar panel 11 are installed above the channel body.

[0050] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
