[0032] In the process of detecting the flow rate of open channels, open channel flow meters are often installed in the river. A typical open channel flow meter consists of mounting rods installed on two inclined sidewalls of the river channel, and connecting rods that connect to the two mounting rods at both ends. The mounting rods are inclined, and ultrasonic transducers are mounted on both rods. The lower side of the connecting rod is used to fix the connection to the riverbed, and a cable is fixed therefor, which is used to electrically connect to the transducers. However, the width of the riverbed varies in different rivers, making it difficult to adapt the connecting rods to different river widths.

[0033] This utility model proposes a device for measuring the flow rate of an open channel.

[0034] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the open channel flow measurement device includes two mounting parts 1, two ultrasonic transducer components 2, and a telescopic rod 3. The two mounting parts 1 are respectively installed on opposite side walls of the river channel. The two ultrasonic transducer components 2 are respectively installed on the two mounting parts 1, and each ultrasonic transducer component 2 includes an ultrasonic transducer 21. The telescopic rod 3 is located between the two mounting parts 1, and both mounting parts 1 are hinged to the telescopic rod 3. The telescopic rod 3 is located at the bottom of the river channel and is used to accommodate cables.

[0035] In the technical solution of this utility model, when installed in a river, the length of the telescopic rod 3 can be adjusted to adapt to the width of the riverbed. Then, the telescopic rod 3 is fixed to the bottom of the river, and the two mounting parts 1 are respectively installed on the opposite side walls of the river. By accommodating the cable inside the telescopic rod 3, the cable in the river can be fixed. By adjusting the length of the telescopic rod 3, it can be adapted to riverbeds of different widths, thus improving the problem of difficulty in adapting to riverbeds of different widths.

[0036] All cables are waterproof. The telescopic rod 3 and the mounting part 1 can be connected by a spherical hinge or a ball joint, which is not limited here; when the telescopic rod 3 and the mounting part 1 are connected by a ball joint, the rotation range of the mounting part 1 is larger; specifically, the telescopic rod 3 and the mounting part 1 are connected by a spherical hinge. The rotation axis of the mounting part 1 is perpendicular to the extension direction of the mounting part 1 and the extension direction of the telescopic rod 3.

[0037] Please see Figure 2 and Figure 3 The telescopic rod 3 includes two first sleeves 31 and a second sleeve 32 disposed between the two sleeves. The two ends of the second sleeve 32 are slidably disposed in the two first sleeves 31 respectively. Both ends of the second sleeve 32 are open to allow the cable to pass through the first sleeve 31 and the second sleeve 32.

[0038] By providing the first sleeve 31 and the second sleeve 32, with both ends of the second sleeve 32 open, the cable can easily pass through the second sleeve 32 for secure installation. When the telescopic rod 3 retracts, the cable can bend to be housed within the telescopic rod 3; when the telescopic rod 3 extends, the cable can straighten to adapt to changes in the length of the telescopic rod 3. Both ends of the first sleeve 31 are open to facilitate the cable passing through the telescopic rod 3. Both the first sleeve 31 and the second sleeve 32 can be cylindrical or square, without limitation; specifically, both the first sleeve 31 and the second sleeve 32 are square cylinders.

[0039] Please see Figure 3 , Figure 4 and Figure 5 A first limiting portion 311 protrudes from the inner side of one end of the two first sleeves 31 that are close to each other, and a second limiting portion 321 protrudes from the outer side of the second sleeve 32 corresponding to the first limiting portion 311. When the telescopic rod 3 is extended so that the first sleeve 31 and the second sleeve 32 move away from each other, the first limiting portion 311 can abut against the second limiting portion 321 to limit the movement of the first sleeve 31 and the second sleeve 32 away from each other, thereby reducing the likelihood of the first sleeve 31 and the second sleeve 32 disengaging from each other.

[0040] The first sleeve 31 has a first opening 312 at its bottom, and the second sleeve 32 has a second opening 322 at its bottom. The width of the first opening 312 is smaller than the width of the second sleeve 32. By providing the first opening 312 and the second opening 322, when the telescopic rod 3 is long, it is convenient to directly adjust the bending of the cable from below through the first opening 312 and the second opening 322, and it is also convenient to inspect the cable. In addition, after the telescopic rod 3 is fixed to the bottom of the river channel, the bottom of the river channel can close the first opening 312 and the second opening 322, reducing cable exposure. Furthermore, by setting the width of the first opening 312, it is possible to prevent the first sleeve 31 and the second sleeve 32 from separating in the vertical direction, thereby improving the stability of the connection between the first sleeve 31 and the second sleeve 32.

[0041] Please see Figure 3 , Figure 4 and Figure 5 The second sleeve 32 has protruding edges 323 on its opposite side walls, with the bottom surface of the protruding edges 323 being flush with the bottom surface of the first sleeve 31. By providing the protruding edges 323, the bottom surfaces of the first sleeve 31 and the second sleeve 32 are made flush, ensuring that the telescopic rod 3 fits snugly against the bottom of the riverbed during the extension and retraction of the telescopic rod 3.

[0042] At least two ultrasonic transducers 21 are spaced apart along the extension direction of the mounting portion 1. Since the flow velocity of water layers at different heights varies, the cooperation of multiple ultrasonic transducers 21 allows for the detection of different water layers from top to bottom, thereby improving detection accuracy.

[0043] Please see Figure 2 and Figure 6 The mounting part 1 includes a first mounting plate with a first hole 11 along its extending direction. The ultrasonic transducer 21 is fitted with a first bolt hole 211 corresponding to the first hole 11. The first bolt hole 211 and the first hole 11 are used for bolts to pass through sequentially. By providing the first mounting hole and the first bolt hole 211, the position of the ultrasonic transducer 21 can be easily adjusted as needed, improving the adjustability of the ultrasonic transducer 21's position, thereby allowing the height of the ultrasonic transducer 21 to be adjusted as needed.

[0044] Two first holes 11 are provided in parallel, and four first bolt holes 211 are provided at the four corners of the ultrasonic transducer 21. The four first bolt holes 211 include two sets, and the two sets of first bolt holes 211 correspond to two first holes 11 respectively, which further ensures the stability of the installation of the ultrasonic transducer 21.

[0045] The mounting part 1 has a mounting cavity 13 for accommodating a cable. The first mounting plate has a second hole 12 along its extension direction. The second hole 12 communicates with the mounting cavity 13 and is used for the cable to pass through.

[0046] The mounting part 1 has a mounting cavity 13 for accommodating cables. A cable routing hole 14 is provided at the end of the mounting part 1 away from the telescopic rod 3, and the cable routing hole 14 communicates with the mounting cavity 13. By providing the cable routing hole 14, it is convenient to insert part of the cable into the mounting cavity 13 from the top. A cable routing hole 14 can also be provided at the end of the mounting part 1 near the telescopic rod 3 for cables to pass through.

[0047] The mounting part 1 is provided with anchoring holes 15 at intervals along its extension direction, and the anchoring holes 15 are used for anchor rods to pass through. By providing anchoring holes 15, the mounting part 1 can be easily fixed to the side wall of the river channel.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
