Description

Technical Field

[0001] This utility model relates to the technical field of mounting brackets, and in particular to a mounting bracket for an integrated radar and ultrasonic flow meter. Background Technology

[0002] Radar-ultrasonic integrated flow meters can be used to monitor the flow rate and water level in storm and sewage pipes. They are typically fixed to the top of the pipe using a mounting bracket. Currently, the most common mounting bracket is an integrated L-shaped bracket. The vertical side of the L-shaped bracket is fixed to the inner wall of the inspection well with expansion bolts, while the horizontal side of the L-shaped bracket extends into the pipe for the flow meter to be installed.

[0003] Since the flow meter is located inside the rainwater and sewage pipes, if the flow meter needs to be repaired or replaced, it is not only inconvenient for the staff to directly enter the pipe to disassemble the flow meter, but also poses safety hazards such as water flow impact. Removing the L-shaped bracket from the inner wall of the inspection well is not only inconvenient to handle, but also requires loosening the nuts of the expansion bolts. The connection between the expansion bolts and the inspection well is subject to repeated vibrations, which may also cause the bracket to loosen and affect its stability. Utility Model Content

[0004] To facilitate the installation and disassembly of flow meters more conveniently and safely, this utility model provides a mounting bracket for an integrated radar and ultrasonic flow meter.

[0005] The mounting bracket for an integrated radar and ultrasonic flow meter provided by this utility model adopts the following technical solution: A mounting bracket for an integrated radar and ultrasonic flow meter includes a fixing plate, a connecting plate, and a mounting plate. The upper half of the fixing plate has fixing holes for expansion bolts to pass through. The lower half of the fixing plate is vertically fixed with multiple fixing screws. The connecting plate has multiple connecting holes adapted to the fixing screws. The fixing screws are detachably passed through the connecting holes and fixed by fixing nuts. The mounting plate is vertically connected to the bottom of the connecting plate and has mounting holes. The flow meter is fixed to the bottom of the mounting plate by bolts passing through the mounting holes.

[0006] By adopting the above technical solution, when the flow meter needs to be disassembled or installed, it is only necessary to remove the connecting plate from the fixing plate without loosening the nuts of the expansion bolts or disassembling the fixing plate. This not only makes it easier for workers to remove the flow meter, connecting plate and mounting plate, improving the convenience of installation or disassembly, but also reduces the impact on the expansion bolt connection and improves the stability of the mounting bracket. At the same time, workers do not need to enter the pipeline to operate, but only need to operate in the inspection well, which improves the safety of workers.

[0007] Preferably, the fixing plate includes a fixing base plate, with fixing ribs vertically fixed to the left and right sides of the fixing base plate, and fixing holes and fixing screws located on the fixing base plate; the connecting plate includes a connecting base plate, with connecting ribs vertically fixed to the left and right sides of the connecting base plate, and connecting holes located on the connecting base plate; the mounting plate includes a mounting base plate, with mounting ribs vertically fixed to the left and right sides of the mounting base plate, and mounting holes located on the mounting base plate.

[0008] By adopting the above technical solutions, the overall structure of the fixing plate composed of the fixing substrate and the fixing rib has good strength and high stability; the overall structure of the connecting plate composed of the connecting substrate and the connecting rib has good strength and high stability; and the overall structure of the mounting plate composed of the mounting substrate and the mounting rib has good strength and high stability.

[0009] Preferably, the connecting substrate and the mounting substrate are perpendicularly fixed together, and the connecting rib is perpendicularly fixed together with the mounting rib.

[0010] By adopting the above technical solution, the connecting plate and the mounting plate are fixedly connected, resulting in good structural stability and ease of production.

[0011] Preferably, the connecting plate and the mounting plate are slidably connected, and a positioning mechanism for limiting the movement of the mounting plate is also provided between the connecting plate and the mounting plate.

[0012] By adopting the above technical solution, the mounting plate and the connecting plate are slidably connected. When disassembling the flow meter, there is no need to disassemble the connecting plate. Only the restriction of the positioning mechanism on the mounting plate needs to be released. At the same time, the mounting plate can be pulled to move the flow meter from the pipeline to the inspection well, so as to facilitate the operation of the staff.

[0013] Preferably, a sliding plate is fixedly connected to the bottom of the connecting rib, a sliding strip is fixedly connected to the sliding plate, and a sliding hole is opened along the length direction on the mounting rib, through which the sliding strip passes.

[0014] By adopting the above technical solution, the slide bar is inserted into the slide hole, and the mounting rib can move along the slide bar. The slide bar provides vertical support for the mounting rib on the one hand, and restricts the rotation of the mounting rib on the other hand.

[0015] Preferably, the positioning mechanism includes a positioning plate rotatably connected to the surface of the connecting substrate, a positioning screw fixedly connected to the end of the positioning plate away from the connecting substrate, a mounting back plate fixedly connected between the two mounting ribs and the mounting substrate, a positioning hole provided on the mounting back plate, and the positioning screw detachably passing through the positioning hole and fixed by a positioning nut.

[0016] By adopting the above technical solution, when it is necessary to position the mounting plate, simply insert the positioning screw into the positioning hole, and then use the positioning nut to fix the positioning screw. The operation is simple.

[0017] Preferably, the positioning mechanism further includes two positioning tubes fixed to the surface of the connecting substrate, with a gap between the two positioning tubes, and a positioning shaft rotatably passing through the two positioning tubes, with a positioning plate vertically fixed to the middle of the positioning shaft.

[0018] By adopting the above technical solution, the positioning shaft rotates inside the two positioning tubes, which can achieve the effect of vertical flipping of the positioning plate. This connection structure is easy to manufacture.

[0019] Preferably, a torsion spring is sleeved on the positioning shaft, and the torsion spring is elastically connected between the connecting base plate and the positioning plate. The torsion spring has an elastic tendency to drive the positioning plate to flip upward.

[0020] By adopting the above technical solution, the torsion spring elastically drives the positioning plate to flip upward, so as to avoid the positioning plate from interfering with the sliding of the mounting plate and getting hooked on the bolts used to fix the flow meter.

[0021] Preferably, a stop block for limiting the rotation range of the positioning plate is fixed to the surface of the connecting substrate, and the stop block is located above the positioning plate.

[0022] By adopting the above technical solution, the hard impact of the positioning plate and positioning screw on the connecting substrate after flipping upwards is avoided. Attached Figure Description

[0028] The following combination Figures 1-4The present invention will be described in further detail below.

[0029] This utility model discloses a mounting bracket for an integrated radar and ultrasonic flow meter. Example 1

[0030] Reference Figure 1 and Figure 2 The flow meter 1 is fixed inside the pipe by a mounting bracket. The mounting bracket for the radar and ultrasonic integrated flow meter includes a fixing plate 2, a connecting plate 3, and a mounting plate 4.

[0031] The fixing plate 2 includes a vertically arranged fixing base plate 20. The upper half of the fixing base plate 20 has multiple fixing holes 200 for inserting expansion bolts to fix the fixing base plate 20 to the inner wall of the inspection well. Vertically arranged fixing ribs 21 are respectively fixed to the left and right sides of the fixing base plate 20 to increase the strength of the fixing plate 2. Multiple fixing screws 22 are vertically fixed to the lower half of the fixing base plate 20. The fixing screws 22 can be fixed by riveting or welding. Fixing nuts 23 are detachably threaded on the fixing screws 22.

[0032] The connecting plate 3 includes a vertically arranged connecting base plate 30. The connecting base plate 30 has connecting holes 300 that correspond to the number and position of the fixing screws 22. The fixing screws 22 pass through the connecting holes 300 and are fixed by fixing nuts 23, thereby fixing the connecting base plate 30 to the fixing base plate 20. The fixing nuts 23 can be cap nuts. Vertically arranged connecting ribs 31 are respectively fixed vertically on the left and right sides of the connecting base plate 30 to increase the strength of the connecting plate 3. The distance between the outer walls of the two connecting ribs 31 is less than the distance between the inner walls of the two fixing ribs 21.

[0033] Mounting plate 4 includes a horizontally arranged mounting base plate 40. One end of the mounting base plate 40 is vertically fixed to the bottom end of the connecting base plate 30. The mounting base plate 40 has multiple mounting holes 400. The flow meter 1 can be fixed to the bottom of the mounting base plate 40 by bolts passing through the mounting holes 400. Mounting ribs 41 are vertically fixed to the left and right sides of the mounting base plate 40 to increase the strength of the mounting plate 4. The mounting ribs 41 are also vertically fixed to the connecting ribs 31.

[0034] The implementation principle of Embodiment 1 is as follows: The mounting bracket in this embodiment is also L-shaped, but the difference from the mounting bracket in the prior art is that the mounting bracket in this embodiment adopts a separate combination structure of connecting plate 3 and fixing plate 2. The connecting plate 3 is fixed on the fixing plate 2 by the cooperation of fixing screw 22 and fixing nut 23.

[0035] When it is necessary to disassemble or install the flow meter 1, simply remove the connecting plate 3 from the fixing plate 2 without loosening the nuts of the expansion bolts or disassembling the fixing plate 2. This not only makes it easier for workers to remove the flow meter 1, connecting plate 3, and mounting plate 4, improving the convenience of installation or disassembly, but also reduces the impact on the expansion bolt connection, improves the stability of the mounting bracket, and eliminates the need for workers to enter the pipeline to operate, allowing them to operate only in the inspection well, thus improving the safety of workers. Example 2

[0036] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the mounting plate 4 and the connecting plate 3 in this embodiment are separate and combined structures, and the mounting plate 4 can slide relative to the connecting plate 3. Specifically, a sliding plate 32 is fixedly connected to the bottom of the connecting rib 31, and a cuboid sliding strip 33 is fixedly connected to the outer side of the sliding plate 32. Correspondingly, a sliding hole 410 is formed along the length direction on the mounting rib 41. The sliding plate 32 fits against the inner side of the mounting rib 41, and the sliding strip 33 slides through the sliding hole 410.

[0037] A positioning mechanism 5 is also provided between the connecting plate 3 and the mounting plate 4 to limit their relative movement. The positioning mechanism 5 includes two positioning tubes 50 fixed to the lower half of the connecting base plate 30. The two positioning tubes 50 are arranged laterally and coaxially, with a gap between them. A positioning shaft 51 is rotatably passed between the two positioning tubes 50. A positioning plate 52 is vertically fixed to the middle of the positioning shaft 51. A positioning screw 53 is fixed to the end of the positioning plate 52 away from the positioning shaft 51. The end of the positioning plate 52 is movably supported on the top surface of the mounting base plate 40.

[0038] Correspondingly, a mounting back plate 42 is fixed between the two mounting ribs 41 and the mounting base plate 40. A positioning hole 420 is provided in the middle of the mounting back plate 42. The positioning screw 53 is detachably inserted through the positioning hole 420 and fixed by the positioning nut 54, thereby restricting the movement of the mounting plate 4 relative to the connecting plate 3. The positioning nut 54 can be a cap nut. A torsion spring 55 is also sleeved on the positioning shaft 51. The torsion spring 55 is elastically connected between the connecting base plate 30 and the positioning plate 52. The torsion spring 55 has an elastic tendency to drive the positioning plate 52 to flip upward, so as to avoid the positioning plate 52 rubbing against the sliding of the mounting plate 4 and hooking onto the bolts used to fix the flow meter 1.

[0039] Meanwhile, to prevent the positioning plate 52 and positioning screw 53 from hard impacting the connecting base plate 30 after flipping upward, it is necessary to control the range of motion of the positioning plate 52. Therefore, a stop block 56 is fixed on the surface of the connecting base plate 30 and above the positioning plate 52. The cross-section of the stop block 56 is a right-angled triangle. When the positioning plate 52 is flipped upward to a horizontal state, it can be blocked by the stop block 56, thereby limiting the positioning plate 52 from continuing to flip upward. At this time, the positioning plate 52 and positioning screw 53 will not interfere with the use of the fixing screw 22 and fixing nut 23.

[0040] The implementation principle of Embodiment 2 is as follows: the slide bar 33 is inserted into the slide hole 410, the slide bar 33 provides vertical support for the mounting rib plate 41, and at the same time the slide bar 33 can restrict the mounting plate 4 from flipping, so that the mounting plate 4 can only slide along the extension direction of the slide hole 410; when it is necessary to disassemble the flow meter 1, first loosen the positioning nut 54, and then pull the mounting plate 4 towards the center of the inspection well. At this time, the positioning screw 53 disengages from the positioning hole 420 and flips upward under the elastic drive of the torsion spring 55 until it abuts against the stop block 56.

[0041] Meanwhile, continue pulling the mounting plate 4 towards the center of the inspection well until it can no longer be pulled; at this point, all the mounting holes 400 have moved from inside the pipe to inside the inspection well, and the staff can directly loosen the nuts used to fix the flow meter 1 and remove the flow meter 1. Compared with the first embodiment, the flow meter 1 can be disassembled without removing the connecting plate 3, and the whole process only requires loosening the positioning nut 54 and moving the mounting plate 4, which is more convenient and efficient in operation.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
