Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water metering, in particular to a canal flow meter. Background Art
[0002] Channel flowmeters, also known as open channel flowmeters, are categorized by their measurement principles into ultrasonic, Doppler, and multi-channel open channel flowmeters. These are all monitoring devices used to measure fluid flow in open channels or channels. Open channel flowmeter monitoring systems are suitable for flow measurement in rectangular and trapezoidal open channels and culverts, particularly in reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, agricultural irrigation, and water resources administration.
[0003] Ultrasonic open channel flowmeters are particularly common in canal flow measurement. During installation, ultrasonic open channel flowmeters require a bracket that spans the canal as an installation carrier. Existing mounting brackets are basically welded frames with non-adjustable spans. Therefore, for canals of different widths, mounting brackets of different lengths often need to be processed during construction.
[0004] Based on the above technical problems, in order to adapt to canals of different widths, the inventors designed and developed a new type of canal flow meter. Utility Model Content
[0005] The utility model aims to solve the deficiencies of the prior art and provides a water channel flow meter.
[0006] The utility model is realized through the following technical solutions, which provide a canal flowmeter, including a mounting bracket for spanning a canal with an adjustable span and for mounting an ultrasonic flowmeter; the mounting bracket includes two upper mounting rods and two lower mounting rods arranged in parallel, the two upper mounting rods and the two lower mounting rods being connected to each other by a supporting mechanism, and the plane where the two upper mounting rods are located is parallel to the plane where the two lower mounting rods are located; a mounting plate spans the two upper mounting rods, and the two upper mounting rods can slide along the length direction of the mounting plate and can be locked in place by a locking member; a lifting adjustment mechanism for adjusting the height of the ultrasonic flowmeter is provided on the mounting plate; and the two lower mounting rods are respectively mounted on the canal tops on both sides of the canal.
[0007] Preferably, the support mechanism includes two groups of support components arranged side by side, each group of support components includes two hinged support rods, the upper ends of the two support rods are respectively fixed to the two upper mounting rods, and the lower ends of the two support rods are respectively fixed to the two lower mounting rods.
[0008] Preferably, the mounting plate is located between the two sets of support assemblies.
[0009] Preferably, a connecting screw is fixed on each upper mounting rod, and a long hole corresponding to each connecting screw and for the connecting screw to pass through is provided on the mounting plate, and the position of the connecting screw can be adjusted along the long hole.
[0010] Preferably, the locking member is a locking nut that is threadedly connected to the connecting screw and is used to compress the mounting plate. When the locking nut is loosened, the two upper mounting rods can slide along the length of the mounting plate, thereby adjusting the spacing between the two upper mounting rods. At the same time, the support mechanism can simultaneously adjust the spacing between the two lower mounting rods. Adjusting the spacing between the two lower mounting rods can then achieve span adjustment.
[0011] Preferably, the lifting adjustment mechanism includes an adjusting screw that vertically passes through the mounting plate, a mounting seat is fixed at the lower end of the adjusting screw, and the ultrasonic flowmeter is fixed on the mounting seat.
[0012] Preferably, an upper adjusting nut and a lower adjusting nut are threadedly connected to the adjusting screw, and the upper and lower adjusting nuts are located on the upper and lower sides of the mounting plate, respectively. By adjusting the positions of the upper and lower adjusting nuts, the adjusting screw can be raised and lowered, thereby adjusting the height of the ultrasonic flowmeter. When the span of the mounting bracket is adjusted, the height of the ultrasonic flowmeter also changes accordingly. Therefore, when the span is adjusted, the height of the ultrasonic flowmeter can be adaptively adjusted through the lifting and lowering adjustment mechanism.
[0013] Preferably, a connecting ear plate is installed on each lower mounting rod, a mounting hole is provided on each connecting ear plate, and the connecting ear plate is fixed to the channel top by bolts.
[0014] The beneficial effects of the utility model are:
[0015] 1. The design inspiration of the inventor of this application comes from "Ma Zha", and this design concept is applied to the bracket structure of the flow meter. Based on the structural form with adjustable span, it can meet the installation needs of channels of different widths. It has a simple structure, low manufacturing cost, a wide range of applications, and has promotion prospects.
[0016] 2. When the locking nut is loosened, the two upper mounting rods can slide along the length direction of the mounting plate, thereby realizing the adjustment of the distance between the two upper mounting rods. At the same time, with the help of the support mechanism, the distance between the two lower mounting rods can be adjusted synchronously. The adjustment of the distance between the two lower mounting rods can then realize the span adjustment.
[0017] 3. By adjusting the position of the upper and lower adjusting nuts, the adjusting screw can be raised and lowered, thereby adjusting the height of the ultrasonic flowmeter. When the span of the mounting bracket is adjusted, the height of the ultrasonic flowmeter will also change.

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.
[0023] like Figure 1-2 As shown, the utility model includes a mounting bracket for spanning a water channel 1 with an adjustable span and for mounting an ultrasonic flowmeter 2. The mounting bracket includes two upper mounting rods 3 and two lower mounting rods 4 arranged in parallel. The two upper mounting rods 3 are connected to the two lower mounting rods 4 by a supporting mechanism, and the plane where the two upper mounting rods 3 are located is parallel to the plane where the two lower mounting rods 4 are located. The mounting plate 10 spans the two upper mounting rods 3. Both upper mounting rods 3 can slide along the length direction of the mounting plate 10 and can be locked in place by a locking member. A lifting and adjusting mechanism for adjusting the height of the ultrasonic flowmeter 2 is provided on the mounting plate 10. The two lower mounting rods 4 are respectively mounted on the channel top 13 on both sides of the water channel 1.
[0024] In this embodiment, the support mechanism includes two groups of support components arranged side by side, and each group of support components includes two hinged support rods 6. The upper ends of the two support rods 6 are respectively fixed to the two upper mounting rods 3, and the lower ends of the two support rods 6 are respectively fixed to the two lower mounting rods 4.
[0025] In this embodiment, the mounting plate 10 is located between two sets of support components.
[0026] In this embodiment, a connecting screw 11 is fixed to each upper mounting rod 3. The mounting plate 10 is provided with an elongated hole 14 corresponding to each connecting screw 11 and for each connecting screw 11 to pass through. The connecting screw 11 can be adjusted along the elongated hole 14. Furthermore, the locking member is a locking nut 12, which is threadedly connected to the connecting screw 11 and is used to press the mounting plate 10. When the locking nut 12 is loosened, the two upper mounting rods 3 can slide along the length of the mounting plate 10, thereby adjusting the spacing between the two upper mounting rods 3. Simultaneously, the support mechanism can be used to simultaneously adjust the spacing between the two lower mounting rods 4. Adjusting the spacing between the two lower mounting rods 4 further achieves span adjustment.
[0027] In this embodiment, the lifting and adjusting mechanism includes an adjusting screw 7 that vertically passes through the mounting plate 10. A mounting base 15 is fixed at the lower end of the adjusting screw 7, and the ultrasonic flowmeter 2 is fixed on the mounting base 15. An upper adjusting nut 9 and a lower adjusting nut 8 are threadedly connected to the adjusting screw 7, and the upper adjusting nut 9 and the lower adjusting nut 8 are respectively located on the upper and lower sides of the mounting plate 10. By adjusting the positions of the upper adjusting nut 9 and the lower adjusting nut 8, the lifting and lowering adjustment of the adjusting screw 7 can be achieved, thereby achieving the height adjustment of the ultrasonic flowmeter 2. When the span of the mounting bracket is adjusted, the height of the ultrasonic flowmeter 2 will also change accordingly. Therefore, when the span is adjusted, the height of the ultrasonic flowmeter 2 can be adaptively adjusted through the lifting and lowering adjustment mechanism.
[0028] In this embodiment, a connecting lug plate 5 is installed on each lower mounting rod 4 , and a mounting hole is provided on each connecting lug plate 5 . The connecting lug plate 5 is fixed to the channel top 13 by bolts.
[0029] When in use, the mounting bracket with the ultrasonic flowmeter 2 is mounted on the canal 1 and fixed to the canal top 13. At the same time, the span of the mounting bracket can be adaptively adjusted in advance according to the width of the canal 1, thereby meeting the installation needs of canals 1 of different widths.
[0030] The inventor of this application was inspired by the design of "Ma Zha", and applied this design concept to the bracket structure of the flow meter. Based on the span-adjustable structural form, it can meet the installation needs of channels 1 of different widths. It has a simple structure, low manufacturing cost, a wide range of applications, and has promotion prospects.
