[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figures 1-6 As shown, this embodiment provides an ultrasonic flow meter certification and testing device, including a housing, a flow channel in the middle of the housing, sensors 20 on the inner walls of opposite sides of the housing, and water-facing slopes on the edges of the housing.

[0035] By setting a water-facing slope at the edge of the housing, water can flow smoothly into the flow channel, reducing turbulence and vortices caused by water flow impact and reducing water flow resistance. At the same time, in conjunction with the sensor 20 on the inner wall of the housing, the detection environment can be stabilized, improving the accuracy of flow measurement, thereby increasing the pass rate of ultrasonic flow meter certification testing, reducing rework caused by detection errors, and reducing resource waste.

[0036] Based on the above technical solution, the box body includes a first side plate 11, a second side plate 12 and a third top plate 13, wherein the first side plate 11, the third top plate 13 and the second side plate 12 are connected in sequence and enclose each other to form the flow channel.

[0037] The first side plate 11, the second side plate 12 and the third top plate 13 form a rectangle with an open bottom. The rectangle formed is the flow channel. The flow channel has a regular shape and is easy to process and manufacture. Its simple structure makes it easy to assemble and maintain, reducing equipment production and subsequent maintenance costs.

[0038] Specifically, the first side plate 11 and the second side plate 12 are parallel, and the third top plate 13 is perpendicular to the first side plate 11 and the second side plate 12 respectively.

[0039] Based on the above technical solution, at least two connecting rods 30 are also provided, the two connecting rods 30 are spaced apart, and the two ends of each connecting rod 30 are fixedly connected to the lower ends of the first side plate 11 and the second side plate 12, respectively.

[0040] The spaced connecting rods 30 fix the lower ends of the first side plate 11 and the second side plate 12, which can enhance the connection strength of the two side plates, stabilize the flow channel while simplifying the structure, ensure the overall stability of the device, ensure the reliability of the detection data of the sensor 20, and extend the service life of the equipment.

[0041] Specifically, one end of the first side plate 11 is connected to one end of the third top plate 13, the other end of the third top plate 13 is connected to one end of the second side plate 12, the other end of the second side plate 12 is connected to one end of the connecting rod 30, and the other end of the connecting rod 30 is connected to the other end of the first side plate 11, thereby forming a rectangular flow channel.

[0042] Based on the above technical solution, the connecting rod 30 is cylindrical in shape.

[0043] The columnar connecting rod 30 can reduce the resistance when water flows through it, avoid local vortex interference caused by the irregular shape of the connecting rod 30, further optimize the water flow state in the flow channel, improve the accuracy of flow measurement, and ensure the accuracy of certification testing.

[0044] Based on the above technical solution, at least two reinforcing rods 40 are provided at the top of the third top plate 13, and the two ends of the reinforcing rods 40 are fixedly connected to the upper ends of the first side plate 11 and the second side plate 12, respectively.

[0045] The reinforcing rod 40 at the top of the third top plate 13 connects to the upper ends of the first side plate 11 and the second side plate 12, which can enhance the stability of the upper structure of the box, prevent the side plates from expanding outward due to pressure on the top plate or water flow impact, ensure the rigidity of the overall flow channel structure, maintain the consistency of the flow channel shape during long-term use, and improve the reliability of equipment operation.

[0046] Based on the above technical solution, a connecting plate 50 is also provided at the top of the third top plate 13. The connecting plate 50 is located in the middle of the third top plate 13, and a column 60 is fixedly provided on the connecting plate 50. The column 60 is perpendicular to the third top plate 13.

[0047] The connection plate 50 and the column 60 provide stable installation support points for the equipment, making it easy to fix the device in the detection system and reduce measurement errors caused by equipment shaking during the detection process. At the same time, the design of the column 60 being perpendicular to the third top plate 13 can ensure the verticality of the device installation and optimize the state of water flow entering the flow channel.

[0048] In a specific example, one end of the column 60 is fixed to the tractor, and the tractor drives the detection device to perform corresponding detection and certification in the detection environment, that is, the tractor drives the detection device to move in the water in a direction perpendicular to the column 60.

[0049] Based on the above technical solution, the sensor 20 includes a first ultrasonic sensor and a second ultrasonic sensor. A plurality of first ultrasonic sensors are evenly spaced on the inner wall of the first side plate 11, and a plurality of second ultrasonic sensors are arranged on the inner wall of the second side plate 12 in a one-to-one correspondence with the first ultrasonic sensors.

[0050] Multiple ultrasonic sensors, one-to-one corresponding to the first side plate 11 and the second side plate 12, can realize the synchronous acquisition of multiple sets of flow data. By comparing and analyzing multiple sets of data, the impact of single sensor error on the detection results can be reduced, the accuracy and reliability of measurement data can be improved, thereby enhancing the reliability of certification testing.

[0051] Specifically, the first side plate 11 includes a first inner plate 111 and a first outer plate 112, which are spaced apart. The first inner plate 111 has a first through hole, and a fixing block 70 is provided corresponding to the first through hole. The first ultrasonic sensor is disposed in the fixing block 70 and is fixed in the fixing block 70 by a clamping block 80, thereby placing the first ultrasonic sensor on the first inner plate 111. A first reinforcing rib 90 is provided in the middle of the first inner plate 111. The first reinforcing rib 90 extends from the upper end to the lower end of the first inner plate 111 and has a trapezoidal cross section. By providing the trapezoidal reinforcing rib, the structural strength and deformation resistance of the first side plate 11 are enhanced.

[0052] Specifically, the second side plate 12 includes a second inner plate 121 and a second outer plate 122, which are spaced apart. The second inner plate 121 has a second through hole, and a fixing block 70 is provided corresponding to the second through hole. The second ultrasonic sensor is disposed in the fixing block 70 and is fixed in the fixing block 70 by a clamping block 80, thereby placing the second ultrasonic sensor on the second inner plate 121. A second reinforcing rib 100 is provided in the middle of the second inner plate 121. The second reinforcing rib 100 extends from the upper end to the lower end of the second inner plate 121. The cross-section of the second reinforcing rib 100 is trapezoidal. By providing the trapezoidal reinforcing rib, the structural strength and deformation resistance of the second side plate 12 are enhanced.

[0053] By setting trapezoidal reinforcing ribs, the overall rigidity of the device is improved, the structural performance of the equipment is optimized, the accuracy of ultrasonic sensor detection data is ensured, and the service life of the equipment is extended.

[0054] Based on the above technical solution, the first ultrasonic sensor and the second ultrasonic sensor are at a preset angle.

[0055] The first and second ultrasonic sensors are positioned at a preset angle, which optimizes the propagation path of ultrasonic waves in the water flow, reduces signal attenuation, improves the sensitivity of signal reception, adapts to the detection requirements under different flow rates, and ensures that accurate measurement data can be obtained under various flow conditions.

[0056] Specifically, the planes where the first and second ultrasonic sensors are located are parallel to the third top plate 13, which are set up in a one-to-one correspondence.

[0057] Specifically, the preset angle is the angle between the line connecting the installation positions of the first ultrasonic sensor and the second ultrasonic sensor and the normal of the first side plate 11 or the second side plate 12.

[0058] Based on the above technical solution, the preset angle is 15°.

[0059] The preset angle is 15°, which is an optimized angle parameter that can accurately locate the reflected waves on the water surface, reduce signal deviation caused by water turbulence or floating objects, and enable the sensor to stably acquire high-quality detection signals at this angle, thereby further improving the accuracy of flow measurement.

[0060] Based on the above technical solution, the water-facing slope has a 30° chamfer.

[0061] The 30° chamfered water-facing slope balances the water flow guidance effect and the resistance, effectively reducing the impact when the water enters the flow channel and ensuring a smooth transition. It also avoids increasing the water flow resistance due to an excessively large slope angle, ensuring a stable flow field within the flow channel, providing a stable detection environment for the sensor, and improving the accuracy of certification testing.

[0062] The ultrasonic flow meter certification and testing device of this utility model has a simple structure. By setting a water-facing slope at the edge of the housing, it can guide the water flow smoothly into the flow channel, reduce turbulence and vortex caused by water flow impact, and reduce water flow resistance. At the same time, in conjunction with the sensor 20 on the inner wall of the housing, it can ensure a stable testing environment, improve the accuracy of flow measurement, thereby increasing the pass rate of ultrasonic flow meter certification and testing, reducing rework caused by testing errors, and reducing resource waste.
