Technical Field
[0001] This utility model relates to the field of fluid metering and testing technology, and in particular to a water meter testing device that is easy to use in the field. Background Technology
[0002] A water meter is an instrument that measures water flow, mostly measuring the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. Water meter testing refers to the process of systematically testing and evaluating the metering performance, operating status, and related parameters of a water meter, aiming to ensure its accuracy and reliability, and to safeguard the fairness of water resource transactions and management efficiency.
[0003] In the existing technology, due to the limitations of building space and installation habits, water pipes near water meters are usually laid close to the wall or the ground, which makes it impossible for ordinary fixing devices to be installed stably around the outside of the pipe. At the same time, rigid clamps are prone to scratching the surface of the pipe, and when dealing with pipes of different diameters, uneven pressure can easily cause the ultrasonic sensor to fail to couple. Utility Model Content
[0004] This utility model discloses a water meter testing device that is easy to use on site. It aims to solve the technical problems that ordinary fixing and clamping devices cannot be stably installed because water pipes are usually laid close to walls or the ground. At the same time, rigid clamping is easy to scratch the surface of the pipe, and it is easy to cause the ultrasonic sensor coupling failure when dealing with pipes of different diameters.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a water meter testing device that is easy to use on-site, comprising: a mounting box, wherein connecting rods are fixedly connected to the outer walls of both opposite sides of the mounting box; mounting seats, wherein two mounting seats are fixedly connected to the ends of the corresponding connecting rods away from the mounting box; and an adaptive installation module, which is located on the two connecting rods and the two mounting seats. The adaptive installation module includes two sliding plates, both of which slide outside the corresponding connecting rods. Multiple pressure spring rods are fixedly connected at equal distances to the opposite sides of the two sliding plates. The ends of the multiple pressure spring rods on the same sliding plate away from the corresponding sliding plate are fixedly connected to the same contact clamping element. Hollow sliding columns are slidably connected inside the two mounting seats, and suction cups are provided at the lower ends of the two hollow sliding columns. The adaptive installation module also includes a drive motor. A mounting hole is provided on the mounting box, and the drive motor is fixedly connected inside the mounting hole. A winding wheel is fixedly connected to the output end of the drive motor. The winding wheel is located inside the mounting box. The outer periphery of the device has two winding ropes. The ends of both winding ropes away from the winding reel pass through the mounting box and are fixedly connected to one side of the corresponding sliding plate. The upper surfaces of both hollow sliding columns are fixedly connected to telescopic springs. The ends of both telescopic springs away from the hollow sliding columns are fixedly connected to the top inner wall of the corresponding mounting base. Sliding rods are slidably connected inside both hollow sliding columns. Pulling members are fixedly connected to one side of the upper end of both sliding rods, and piston members are fixedly connected to the lower end of both sliding rods. The interiors of the two mounting bases... Each of the two hollow sliding columns is provided with a sliding groove, and a sliding ratchet is slidably connected in each of the two sliding grooves. A push button is fixedly connected to the side of each sliding ratchet that is far apart from each other. An elastic spring is provided in each of the two sliding grooves, and the two elastic springs are in contact with one side of the corresponding sliding ratchet. An annular groove is provided on each of the two hollow sliding columns, and a fixing ring is fixedly connected in each of the two annular grooves. A circular hole is provided on each of the two fixed rings, and a snap-fit rod is fixedly connected in each of the two circular holes. The two snap-fit rods are in contact with the teeth of the corresponding sliding ratchet.
[0006] With an adaptive installation module, the device is placed outside the pipeline. Pressing the mounting box and mounting base causes the hollow sliding column to slide against the inner wall of the mounting base, overcoming the elasticity of the telescopic spring. After being pressed to the appropriate position, the hollow sliding column is relatively fixed due to the engagement of the locking rod and the teeth of the sliding ratchet. The drive motor is started to rotate the winding wheel, and the winding rope pulls the sliding plates on both sides to compress the reset spring and slide along the outside of the limiting rod. The contact clamping part adheres to the outer wall of the pipeline under the action of the pressure spring rod, adaptively clamping and fixing the pipeline. Then, the pulling part pulls the sliding rod and piston to slide upward, reducing the air pressure inside the suction cup and the hollow sliding column, adsorbing and fixing it to the wall or ground. After the test is completed, pressing the push button causes the sliding ratchet to slide, releasing the limiting lock on the hollow sliding column. The device uses pressing, telescopic, and ratchet locking for initial rapid positioning, and can adaptively and flexibly clamp pipelines of different diameters, avoiding damage to the pipeline surface caused by rigid contact of the clamp. Furthermore, the negative pressure adsorption ensures the coupling stability of the sensor and the overall vibration resistance, ensuring high accuracy and reliability of the test.
[0007] In a preferred embodiment, limiting rods are fixedly connected to the outer walls of the opposite sides of the mounting box, and two sliding plates slide outside the corresponding limiting rods. A return spring is wrapped around the outside of the two limiting rods. One end of each return spring is fixedly connected to the outer wall of the mounting box, and the other end is fixedly connected to one side of the corresponding sliding plate. A main body is fixedly connected to one side of the mounting box, and an ultrasonic transmitter and an ultrasonic receiver are provided on the lower end face of the main body.
[0008] As can be seen from the above, the water meter testing device provided by this utility model is easy to use on site. Through the adaptation installation module, it uses the pressing and telescopic combined with ratchet locking for initial and rapid positioning. Then, it can adaptively and flexibly clamp pipes of different diameters to avoid damage to the pipe surface caused by rigid contact of the clamp. Furthermore, the negative pressure adsorption ensures the coupling stability of the sensor and the overall vibration resistance, ensuring high accuracy and reliability of the detection.

[0012] The water meter testing device disclosed in this utility model is easy to use on site. It is mainly used in scenarios where water pipes are usually laid close to walls or the ground, and ordinary fixing clamping devices cannot be installed stably. At the same time, rigid clamping is easy to scratch the pipe surface, and it is easy to cause the ultrasonic sensor coupling failure when dealing with pipes of different diameters.

The adaptive mounting module 6 includes two sliding plates 601, each sliding outside the corresponding connecting rod 2. Multiple pressure spring rods 608 are fixedly connected at equal distances to the opposite side of each sliding plate 601, located on the same sliding plate 601. Multiple pressure spring rods 608 on the upper part are fixedly connected to the same contact clamping member 609 at one end away from the corresponding sliding plate 601. Hollow sliding columns 602 are slidably connected inside the two mounting bases 3. Suction cups 603 are provided at the lower ends of the two hollow sliding columns 602. The adaptable mounting module 6 also includes a drive motor 605. The mounting box 1 has a mounting hole. The drive motor 605 is fixedly connected to the mounting hole. The output end of the drive motor 605 is fixedly connected to a winding wheel 606. The winding wheel 606 is located inside the mounting box 1, and two winding ropes 607 are surrounded around the outside of the winding wheel 606. The ends of ropes 607 away from the winding reel 606 pass through the mounting box 1 and are fixedly connected to one side of the corresponding sliding plate 601. The upper surfaces of the two hollow sliding columns 602 are fixedly connected to telescopic springs 604. The ends of the two telescopic springs 604 away from the hollow sliding columns 602 are fixedly connected to the top inner wall of the corresponding mounting base 3. Sliding rods 610 are slidably connected inside the two hollow sliding columns 602. Pulling members 617 are fixedly connected to one side of the upper end of each of the two sliding rods 610, and piston members 611 are fixedly connected to the lower end of each of the two sliding rods 610. Sliding openings are provided inside both mounting bases 3. The two sliding grooves each have a sliding ratchet 613 slidably connected to them. Each of the two sliding ratchet 613 has a push button 615 fixedly connected to the side of each sliding ratchet 613 that is far apart from each other. Each of the two sliding grooves has an elastic spring 614, and each of the two elastic springs 614 is in contact with one side of the corresponding sliding ratchet 613. Each of the two hollow sliding columns 602 has an annular groove, and each of the two annular grooves has a fixed ring 612 fixedly connected to it. Each of the two fixed rings 612 has a round hole, and each of the two round holes has a locking rod 616 fixedly connected to it. Each of the two locking rods 616 is in contact with the teeth of the corresponding sliding ratchet 613.
[0014] Reference Figure 1In a preferred embodiment, as shown in Figures 1 and 2, limiting rods 4 are fixedly connected to the outer walls of opposite sides of the mounting box 1. Two sliding plates 601 slide outside the corresponding limiting rods 4, and a return spring 5 surrounds the outer side of each limiting rod 4. One end of each return spring 5 is fixedly connected to the outer wall of the mounting box 1, and the other end is fixedly connected to one side of the corresponding sliding plate 601. A main body 7 is fixedly connected to one side of the mounting box 1, and an ultrasonic transmitter 8 and an ultrasonic receiver 9 are provided on the lower end face of the main body 7.
[0015] Working principle: A device is installed on the upstream and downstream sides of a long straight pipe section. The device is positioned outside the pipe. Pressing the mounting box 1 and mounting base 3 causes the hollow sliding column 602 to slide against the inner wall of the mounting base 3, overcoming the elastic force of the telescopic spring 604. Simultaneously, with the relative movement of the hollow sliding column 602 and the mounting base 3, the fixing ring 612 drives the locking rod 616 to engage with the teeth of the sliding ratchet 613. This causes the sliding ratchet 613 to press against the elastic spring 614, allowing the hollow sliding column 602 to slide smoothly. After being pressed to the appropriate position, the contact clamping member 609 is aligned with both sides of the pipe, and the ultrasonic transmitter 8 and ultrasonic receiver 9 are both in contact with the outer wall of the pipe. At this point, due to the engagement of the locking rod 616 and the teeth of the sliding ratchet 613, the hollow sliding column 602 is relatively fixed. The drive motor 605 is then started to drive the winding wheel 60. 6. Rotation causes the winding wheel 606 to tighten the winding rope 607. The winding rope 607 pulls the sliding plates 601 on both sides to compress the reset spring 5, which slides along the outside of the limiting rod 4. The contact clamping part 609, under the action of the pressure spring rod 608, adheres to the outer wall of the pipe, providing adaptive clamping and fixing to the pipe. Then, the pulling part 617 pulls the sliding rod 610 and the piston part 611 upward, causing the air pressure inside the suction cup part 603 and the hollow sliding column 602 to decrease, adsorbing and fixing to the wall or ground. The two ultrasonic transmitters 8 located outside the upstream and downstream pipes alternately emit ultrasonic waves to measure the time difference between downstream and upstream propagation. The real-time flow rate is calculated based on the time difference and compared with the water meter reading to obtain the error. After the test is completed, the push button 615 is pressed to drive the sliding ratchet 613 to slide, releasing the limiting lock on the hollow sliding column 602.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
