Description

Technical Field

[0001] This invention relates to the field of flow testing devices, specifically to a water balance flow testing device and a water balance testing method. Background Technology

[0002] Electronic water meters have the function of recording electronic test information. However, in some extreme weather conditions, such as extremely cold environments, the electronic recording system of electronic water meters is prone to failure and cannot be used. Therefore, mechanical water meters, which are less susceptible to damage, are also needed. However, mechanical water meters do not have data recording functions. Therefore, this water balance test video recorder is installed on the mechanical water meter. The recorder's camera captures the mechanical data on the mechanical water meter, records and organizes it, and transmits it to the terminal to display the mechanical water meter data, making it convenient for users to observe in real time.

[0003] However, existing flow testing devices rely on rigid bolt connections during use, which are insufficient to buffer the impact force generated by pipeline vibration. Long-term vibration can cause bolts to loosen and clips to deform. Furthermore, thermal expansion and contraction of components caused by temperature changes can further aggravate the connection gaps, ultimately causing the device to shift or fall off, directly affecting the relative position of the equipment and the water meter dial. Summary of the Invention

[0004] The purpose of this invention is to provide a water balance test flow device and a water balance test method. By setting up an installation part, the invention solves the problem that existing test flow devices rely on rigid bolt connections during use, which are difficult to buffer the impact force generated by pipeline vibration. Long-term vibration will cause bolts to loosen and clips to deform. Furthermore, the thermal expansion and contraction of components caused by temperature changes will further aggravate the connection gap, eventually causing the device to shift or fall off, directly affecting the relative position of the device and the water meter dial.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a water balance testing flow device and a water balance testing method, comprising a mechanical water meter and a threaded ring threadedly connected to the mechanical water meter. A monitoring device is disposed within the threaded ring. The invention further comprises: a mounting part mounted on the threaded ring; several stabilizing parts, each mounted on the monitoring device; a limiting component mounted on the mechanical water meter; and a protective component disposed on the mechanical water meter. The limiting component includes several limiting blocks fixedly connected to the threaded ring. A first fixing ring is disposed on the outer wall of the threaded ring, and several locking blocks are fixedly connected to the first fixing ring, extending into the limiting blocks. A centering member is disposed on the first fixing ring, and a second fixing ring is disposed above the first fixing ring. The locking blocks are adapted to the limiting blocks. The centering member includes several protrusions fixedly connected to the first fixing ring, each protrusion contacting the threaded ring. Four protrusions are arranged in a circumferential array.

[0007] Furthermore, the stabilizing part includes a hinge assembly mounted on the monitoring device; and a reset assembly mounted on the mounting part, with the hinge assembly connected to the mounting part via the reset assembly.

[0008] Furthermore, the protective assembly includes a spring disposed between a fixed ring and a protrusion. The top of the spring is fixedly connected to the protrusion, and the bottom of the spring is fixedly connected to the fixed ring. A protective cover is disposed between the fixed ring and the protrusion. The top of the protective cover is fixedly connected to the protrusion, and the bottom of the protective cover is fixedly connected to the fixed ring. A plurality of threaded rods are fixedly connected to the top of the fixed ring. The plurality of threaded rods all penetrate the fixed ring. A pressing member is disposed on the plurality of threaded rods. The threaded rods are distributed in a circumferential array. The pressing member includes a plurality of nuts threadedly connected to the plurality of threaded rods. The nuts are hexagonal in shape.

[0009] Furthermore, the hinge assembly includes a limiting groove formed on the monitoring device. The inner wall of the limiting groove is provided with an adapter block. The outer wall of the adapter block is fixedly connected to a hinge block one. Two hinge rods are hingedly arranged on the hinge block one. Each of the two hinge rods is provided with a connector. The two hinge rods are arranged in a mirror image. The connectors include two hinge blocks two respectively hinged to the two hinge rods. The two hinge blocks two are fixedly connected to two fixing rings three respectively.

[0010] Furthermore, the reset assembly includes two fixed rings three slidably connected to the outer wall of the threaded rod, and elastic elements are provided on the two fixed rings three. The two fixed rings three are arranged in a mirror image. The elastic element includes a spring fixedly connected between the two fixed rings three. After installation, the spring is in a compressed state.

[0011] The present invention has the following beneficial effects:

[0012] 1. This invention, through the installation section, first establishes a stable installation benchmark based on the threaded connection between the threaded ring and the water meter; then, through the contact between the protrusion and the second fixing ring, the coaxiality of the first fixing ring and the threaded ring is automatically calibrated to avoid installation misalignment. Subsequently, with the misalignment, downward pressing, rotation, and spring reset actions of the locking block and the limiting block, the elastic force of the first spring is used to complete the axial limiting. Finally, the threaded locking of the stabilizing part and the nut strengthens the fixation, forming a closed-loop operation logic of "positioning-calibration-limiting-reinforcement". The entire process requires no professional tools and relies on the cooperation of the mechanical structure to achieve installation and fixation. It can resist the risk of loosening caused by pipeline vibration and temperature changes, and avoid component displacement during long-term use, ensuring the stability of equipment operation.

[0013] 2. This invention establishes a basic positioning frame by setting up stabilizing parts, pre-positioning the monitoring device within the ring, and initially aligning it with the adapter block through the limiting groove. Then, through the threaded transmission of tightening the nut, the nut is driven to press downwards against the third fixing ring. The axial pressure of the nut causes the spring to contract, thereby bringing the two third fixing rings closer together. The displacement of the third fixing ring is transmitted to the hinge rod through the second hinge block, causing the hinge rod to deflect at an angle, generating an outward thrust on the first hinge block and the adapter block. This ultimately pushes the adapter block into the limiting groove of the monitoring device, completing radial fixation. Simultaneously, the four stabilizing parts synchronously perform the above-mentioned pressing linkage action, forcing the monitoring device to automatically center itself through a uniform radial force, ensuring it remains coaxial with the threaded ring. The engagement of the adapter block and the limiting groove, combined with the synchronous centering action of the four stabilizing parts, forces the monitoring device to align with the threaded ring, preventing misalignment between the camera and the water meter dial caused by installation deviation, providing a solid guarantee for subsequent image recognition.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-7 As shown, the present invention is a water balance test flow device and a water balance test method, including a mechanical water meter 111 and a threaded ring 112 threadedly connected to the mechanical water meter 111. A monitoring device 113 is provided inside the threaded ring 112. The invention also includes: a mounting part 2, which is mounted on the threaded ring 112; and a stabilizing part 3, of which a plurality of stabilizing parts 3 are provided, and each plurality of stabilizing parts 3 is provided on the monitoring device 113.

[0027] The mounting part 2 includes a limiting component 21, which is mounted on the mechanical water meter 111; and a protective component 22, which is disposed on the mechanical water meter 111. The limiting component 21 includes a plurality of limiting blocks 211 fixedly connected to a threaded ring 112. A fixing ring 1 212 is disposed on the outer wall of the threaded ring 112. A plurality of locking blocks 213 are fixedly connected to the fixing ring 1 212, and the locking blocks 213 extend into the limiting blocks 211 respectively. A centering member is disposed on the fixing ring 1 212. A fixing ring 215 is disposed above the fixing ring 1 212. The locking blocks 213 are adapted to the limiting blocks 211. The centering member includes a plurality of protrusions 214 fixedly connected to the fixing ring 1 212. The protrusions 214 are all in contact with the threaded ring 112. There are four protrusions 214 arranged in a circumferential array. The protective component 22 includes a plurality of locking blocks 211 disposed on the fixing ring 1 212 and the threaded ring 112. Spring 221 is located between protrusions 214. The top of spring 221 is fixedly connected to protrusion 214, and the bottom of spring 221 is fixedly connected to fixing ring 212. A protective cover 222 is provided between fixing ring 212 and protrusion 214. The top of protective cover 222 is fixedly connected to protrusion 214, and the bottom of protective cover 222 is fixedly connected to fixing ring 212. Several threaded rods 223 are fixedly connected to the top of fixing ring 212. Several threaded rods 223 pass through fixing ring 215. A pressing component is provided on several threaded rods 223. The threaded rods 223 are arranged in a circumferential array. The pressing component includes several nuts 224 threadedly connected to several threaded rods 223. The nuts 224 are hexagonal. By setting the mounting part 2, it can resist the risk of loosening caused by pipeline vibration and temperature changes, and avoid the displacement of components during long-term use, thus ensuring the stability of equipment operation.

[0028] The stabilizing part 3 includes a hinge assembly 31, which is mounted on the monitoring device 113; and a reset assembly 32, which is mounted on the mounting part 2. The hinge assembly 31 is connected to the mounting part 2 via the reset assembly 32. The hinge assembly 31 includes a limiting groove 311 formed on the monitoring device 113. An adapter block 312 is provided on the inner wall of the limiting groove 311. A hinge block 313 is fixedly connected to the outer wall of the adapter block 312. Two hinge rods 314 are hingedly mounted on the hinge block 313. Each hinge rod 314 is provided with a connector. The two hinge rods 314 are arranged in a mirror image. The connectors include two hinge blocks 315 that are respectively hinged to the two hinge rods 314. Each hinge block 315 is fixedly connected to two fixing rings 321. The reset assembly 32 includes two fixing rings 321 that are slidably connected to the outer wall of the threaded rod 223. The two fixing rings 321 are provided with elastic elements. The two fixing rings 321 are arranged in a mirror image. The elastic elements include springs 322 that are fixedly connected between the two fixing rings 321. After installation, the springs 322 are in a compressed state. By setting the stabilizing part 3, the matching cooperation between the adapter block and the limiting groove, and the synchronous centering effect of the four stabilizing parts, the monitoring device can be forced to be precisely aligned with the threaded ring, avoiding misalignment between the camera and the water meter dial caused by installation offset, and providing a solid guarantee for the high accuracy of subsequent image recognition.

[0029] Monitoring Device 113: The outer shell is made of ABS engineering plastic with an IP68 waterproof rating, allowing it to be completely submerged in water without damage. The inner side of the quick-removable glass cover is coated with an anti-fog coating to prevent fogging of the dial in humid environments. The camera module uses a telephoto fixed-focus lens with a manually adjustable focal length within the 10-30mm range, adaptable to different sizes of mechanical water meters. Four 850nm infrared LEDs surround the lens, with adjustable illumination angles to prevent glare from direct light on the dial, ensuring that even in low-light conditions of 0-50 lux, the dial photos captured have a resolution of at least 1280×720, with clearly visible scales. Functionally, the timing system supports two modes: fixed-time shooting and interval shooting, which can be remotely set via a mobile app. The sleep function is controlled by a low-power chip. The device consumes less than 0.1 mA in its normal operating state, and can work continuously for more than 3 months on a single charge. The battery compartment is designed with magnetic attachment, allowing for battery replacement without tools. Data transmission uses China Mobile / China Unicom IoT cards and supports 4G networks. When the signal strength is below -100dBm, it automatically switches to local storage and resumes transmission automatically when the signal is restored. The device also has data encryption to prevent photos from being tampered with during transmission. In terms of image recognition adaptability, the algorithm has built-in recognition models for pointer and dial-type water meters, which can automatically distinguish the dial type. For pointer water meters, it can recognize scales from 0.1 to 1000 cubic meters with an error of no more than ±0.1 cubic meters. For dial-type water meters, it can recognize one decimal place and can filter out interference such as stains, scratches, and water stains on the dial, with a recognition accuracy of no less than 99.5%.

[0030] In use, first install the threaded ring 112 onto the mechanical water meter 111 via threads. Then, install the fixing ring 212 onto the threaded ring 112. When installing the fixing ring 212, place the protrusion 214 onto the threaded ring 112. During placement, the fixing ring 215 will contact the threaded ring 112, making the fixing ring 212 and the threaded ring 112 coaxial. Then, misalign the locking block 213 and the limiting block 211 on the fixing ring 212. Then, press the fixing ring 212 downward. As the fixing ring 212 moves downward, the spring 221 and the protective cover 222 will extend downward accordingly. When the fixing ring 212 moves, the threaded rod 223 will also move accordingly. When the threaded rod 223 moves, it will slide on the fixed ring 215. After the locking block 213 passes the limiting block 211, the locking block 213 will be rotated to one side of the limiting block 211. When it is rotated to the bottom of the limiting block 211, the fixed ring 212 will be released. At this time, the spring 221 will return to its original position. When it returns to its original position, the fixed ring 212 will also move upward. As it moves, the locking block 213 will extend into the limiting block 211, thereby achieving the limiting effect. Then the stabilizing part 3 can be sleeved on the threaded rod 223. Then the nut 224 is installed on the threaded rod 223 through the thread. Thus, the fixed ring 212 can be installed on the threaded ring 112.

[0031] Before the first fixing ring 212 is fully tightened, the monitoring device 113 is placed inside the threaded ring 112, and the limiting groove 311 is aligned with the corresponding adapter block 312. When tightening, the nut 224 needs to be tightened. As the nut 224 moves downward, it will contact the third fixing ring 321 located above. As it continues to descend, it will compress the spring 322. As it compresses, the two fixing rings 321 will move closer to each other. When they move closer to each other, the second hinge block 315 will also move. When it moves, it will cause the two hinge rods 314 to change angle. When the angle changes, it will push the first hinge block 313 and the adapter block 312 outward. As the adapter block 312 moves, it will be locked into the limiting groove 311. After being locked in, the monitoring device 113 can be restricted on the threaded ring 112. Under the simultaneous compression of the four stabilizing parts 3, the monitoring device 113 will be centered, thereby ensuring that the monitoring device 113 can be accurately aligned with the threaded ring 112.

During placement, the fixing ring two (215) will contact the threaded ring (112), making the fixing ring one (212) and the threaded ring (112) coaxial. Then, offset the locking block (213) and the limiting block (211) on the fixing ring one (212). Then, press the fixing ring one (212) downward. When the fixing ring one (212) moves downward, the spring one (221) and the protective cover (222) will extend downward accordingly. When the fixing ring one (212) moves, the threaded rod (223) will also move accordingly. When the threaded rod (223) moves, it will slide on the second fixed ring (215).
