Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flow meters, and in particular relates to an ultrasonic flow meter which is easy to dismantle and repair. Background Art
[0002] Ultrasonic flowmeter is a non-contact instrument. It can measure the flow rate of large-diameter media and can also be used to measure media that are difficult to contact and observe. Its measurement accuracy is very high and is almost unaffected by the various parameters of the measured medium. In particular, it can solve the flow measurement problems of highly corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot solve. It is widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage and other fields.
[0003] The prior art discloses an ultrasonic flowmeter with a patent announcement number of CN218994459U. The above patent includes a meter head and a support pipe clamp. The meter head is installed on the upper part of the ball head support. The two ends of the ball head support are respectively fixed on the upper part of one side of the support pipe clamp. The right side of the meter head is connected to one end of two data lines, the other end of one data line is connected to the upstream probe, and the other end of the other data line is connected to the downstream probe. The meter head can be rotated at will to facilitate data reading. The pipe clamp can realize the rapid installation and removal of the flowmeter without the need to modify the original pipeline. Pipe clamps of different sizes can be replaced to adapt to pipelines of different diameters. The installation and removal are fast and time-saving. However, there are still the following deficiencies in actual use: from a practical point of view, the pipe clamp of the device cannot adjust its own clamping range. When measuring the flow of pipelines of different diameters, different pipe clamps need to be replaced. One pipe clamp cannot be adapted to pipelines of more diameters. The actual operation is relatively cumbersome and the practicality is relatively low.
[0004] Therefore, there is a need for an ultrasonic flowmeter that is easy to disassemble and repair, so as to solve the problem in the prior art that the ultrasonic flowmeter pipe clamp cannot be adapted for use with pipes of different specifications and diameters. Utility Model Content

DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with the embodiments.
[0022] See also Figure 1-4 The utility model provides an ultrasonic flowmeter which is easy to disassemble and repair, including a flowmeter body 1 and two convex frames 2. Two data cables 3 are fixedly connected to the bottom of the flowmeter body 1, and probes 4 are fixedly connected to the ends of the two data cables 3. Threaded rods 5 are rotatably connected to the tops of the two convex frames 2. Rotating plates 6 are fixedly connected to the tops of the two threaded rods 5. Trapezoidal push blocks 7 are rotatably connected to the bottoms of the two threaded rods 5. Two limiting rods 8 are fixedly connected to the tops of the two trapezoidal push blocks 7. Round rods 9 are slidably connected to the bottoms of the two trapezoidal push blocks 7. Springs 10 are sleeved on the outer walls of the two round rods 9. Clamping mechanisms 11 are provided on the inner walls of the two convex frames 2. Pipes 12 are clamped inside the two clamping mechanisms 11.
[0023] Further as Figure 4As shown, it is worth specifically explaining that the clamping mechanism 11 includes a plurality of fixed blocks 1101 fixedly connected to the inner wall of the convex frame 2, a rotating shaft 1102 is rotatably connected between every two corresponding fixed blocks 1101, the outer walls of the two rotating shafts 1102 are fixedly connected to pipe sleeves 1103, the tops of the two pipe sleeves 1103 are fixedly connected to first guide rods 1104, the inner sides of the two first guide rods 1104 are installed with guide wheels 1105 corresponding to the trapezoidal push blocks 7, the bottoms of the two pipe sleeves 1103 are fixedly connected to second guide rods 1106, the inner sides of the two second guide rods 1106 are installed with arc-shaped clamping plates 1107, and by setting the clamping mechanism 11, the device can adapt to pipes 12 of different diameters, thereby increasing the practicability of the device and facilitating the disassembly and repair of the flow meter.
[0024] Further as Figure 3 As shown, it is worth explaining in detail that the two guide wheels 1105 are rollingly fitted to the outer walls of the trapezoidal push block 7 on both sides, ensuring that the movement of the trapezoidal push block 7 can drive the two guide wheels 1105 to move outward at the same time, thereby providing power for the movement of the arc clamping plate 1107.
[0025] Further as Figure 4 As shown, it is worth explaining in detail that the arc-shaped clamping plate 1107 is installed through a universal joint, and an anti-skid pad is fixedly connected to the inner wall of the arc-shaped clamping plate 1107. Under the action of the universal joint, the arc-shaped clamping plate 1107 can fit the pipe 12 more fully, and the clamping of the pipe 12 is more balanced. At the same time, the anti-skid pad can increase the friction between the pipe 12 and the arc-shaped clamping plate 1107, and further improve the stability of the clamping.
[0026] According to the above working process, it can be known that: by setting the trapezoidal push block 7 and the clamping mechanism 11 to cooperate, the rotating plate 6 rotates the threaded rod 5 to drive the trapezoidal push block 7 to descend, and while the trapezoidal push block 7 descends, it drives the two guide wheels 1105 to roll outward, so that the two first guide rods 1104 rotate outward, and the two second guide rods 1106 drive the arc clamping plates 1107 to move inward, so that the two arc clamping plates 1107 clamp and fix the pipe 12 to be measured, so that the device can adapt to pipes 12 of different diameters, thereby increasing the practicability of the device and facilitating the disassembly and repair of the flow meter.
[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a thread groove corresponding to the threaded rod 5 is opened on the top of the convex frame 2, and the thread groove and the threaded rod 5 cooperate to ensure that the threaded rod 5 can be lifted and lowered while rotating, thereby providing driving force for the lifting and lowering of the trapezoidal push block 7.
[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a through hole corresponding to the limit rod 8 is opened on the top of the convex frame 2, and the limit rod 8 slides on the inner wall of the through hole to limit and guide the movement of the trapezoidal push block 7, so that the lifting and lowering movement of the trapezoidal push block 7 is more stable.
[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the bottom of the round rod 9 is fixedly connected to the top of the probe 4, and the spring 10 is fixedly connected between the bottom of the trapezoidal push block 7 and the top of the probe 4. The round rod 9 and the spring 10 cooperate to enable the probe 4 to flexibly extend and retract at the bottom of the trapezoidal push block 7, thereby buffering and protecting the extrusion force exerted on the probe 4.
[0030] This solution has the following working process: in actual use, the two convex frames 2 are placed on two positions of the outer wall of the pipe to be measured 12, the rotating plate 6 rotates the threaded rod 5 to drive the trapezoidal push block 7 to descend, and while the trapezoidal push block 7 descends, it drives the two guide wheels 1105 to roll outward, so that the two first guide rods 1104 rotate outward, and the two second guide rods 1106 drive the arc clamping plates 1107 to move inward, so that the two arc clamping plates 1107 clamp and fix the pipe to be measured 12, and while clamping and fixing, the trapezoidal push block 7 drives the probe 4 to descend, and the probe 4 is tightly fitted with the outer wall of the pipe to be measured 12, and then the flowmeter body 1 is opened to measure the flow of the pipe 12.
[0031] In summary: by arranging the trapezoidal push block 7 and the clamping mechanism 11 in coordination, the two arc-shaped clamping plates 1107 can clamp and fix the pipe 12 to be measured, so that the device can adapt to pipes 12 of different diameters, thereby increasing the practicality of the device and facilitating the disassembly and repair of the flow meter; by arranging the round rod 9 and the spring 10 in coordination, the probe 4 can be flexibly extended and retracted at the bottom of the trapezoidal push block 7, so that the probe 4 can better fit the pipe 12 to be measured, and at the same time, the extrusion force on the probe 4 is buffered, thereby playing a protective role and avoiding damage to the probe 4 due to excessive clamping force during measurement.
