Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a high-precision rotary vane water meter. Background Technology

[0002] A rotary vane water meter is a common water flow metering device used to measure the amount of water flowing through a water pipe. Its working principle is based on the kinetic energy of the fluid, which drives the rotation of the vane through the water flow, thereby generating a rotational speed proportional to the flow rate.

[0003] In the existing technology, the existing rotary vane water meter mainly uses the water flow speed to drive the impeller to rotate during normal use, and calculates the water consumption by the number of times the impeller rotates. However, when the water flow speed is too slow or the water volume is small, the water flow speed and water volume are insufficient to drive the impeller to rotate, thereby reducing the measurement accuracy of the rotary vane water meter and causing inaccurate meter readings. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that when the water flow speed is too slow or the water volume is small, the impeller cannot be driven to rotate, which leads to a decrease in the measurement accuracy of the rotary vane water meter and inaccurate measurement. Therefore, a high-precision rotary vane water meter is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision rotary vane water meter, comprising a pipe, wherein a limiting component is provided on the inner wall of the pipe, the limiting component includes two first fixing blocks, each of the outer surfaces of the two first fixing blocks having a groove, a sliding shaft being slidably connected between the inner walls of the two grooves, a stop block being fixedly sleeved on the outer surface of the sliding shaft, two second fixing blocks being fixedly connected to one side of the outer surface of the stop block, a first rotating shaft being movably embedded between the inner walls of the two second fixing blocks, and a support block being fixedly sleeved on the outer surface of the first rotating shaft.

[0006] Preferably, the outer surfaces of both first fixing blocks are fixedly connected to the inner wall of the pipe, the outer surface of the stop block is in contact with the inner wall of the pipe, and a slide rail is fixedly connected to the inner wall of the pipe.

[0007] Preferably, the inner wall of the slide rail is provided with a spring, one end of the spring is fixedly connected to the inner wall of the slide rail, and the other end of the spring is fixedly connected to the outer surface of the support block.

[0008] Preferably, the outer surface of the support block is slidably connected to the inner wall of the slide rail, and the outer surfaces of the two first fixed blocks are fixedly connected to a second rotating shaft, and the outer surfaces of the two second rotating shafts are respectively movably embedded in the opposite outer surfaces of the stop blocks.

[0009] Preferably, a first fixed shaft is movably embedded in the inner wall of the pipe, a first counting gear is fixedly sleeved on the outer surface of the first fixed shaft, and a third fixed block is fixedly connected to one end of the first fixed shaft.

[0010] Preferably, an impeller is fixedly sleeved on the outer surface of the third fixed block, an impeller disk is movably connected to the inner wall of the third fixed block, and a water filter screen is fixedly connected to the outer surface of the impeller disk.

[0011] Preferably, a second fixed shaft is movably embedded in the inner wall of the pipe, and a second counting gear is fixedly sleeved on the outer surface of the second fixed shaft. A third fixed shaft is movably embedded in the inner wall of the pipe, and a third counting gear is fixedly sleeved on the outer surface of the third fixed shaft.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the device is equipped with a limiting component. When the water volume is small and the water flow rate is too slow, the water will accumulate on the other side of the baffle. When the water accumulates to a certain extent, the water volume will push the baffle from a near-vertical state to a near-horizontal state. At this time, the water obstruction disappears, and the water flows from the outer surface of the baffle. At this time, the flow rate is faster and the flow rate is also larger, which will drive the impeller to rotate, thereby improving the measurement accuracy of the rotary vane water meter and ensuring the accuracy of the rotary vane water meter measurement.

[0014] 2. In this utility model, the device is equipped with a water filter screen, which can intercept impurities in the water outside the filter screen, thereby reducing the wear of impurities in the water on the impeller inside the filter screen, and thus reducing the cost of maintenance and replacement parts.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-9As shown, this utility model provides a high-precision rotary vane water meter, including a pipe 1. A limiting component 2 is provided on the inner wall of the pipe 1. The limiting component 2 includes two first fixing blocks 201. Grooves 202 are formed on the outer surfaces of both first fixing blocks 201. A sliding shaft 203 is slidably connected between the inner walls of the two grooves 202. A stop block 204 is fixedly sleeved on the outer surface of the sliding shaft 203. Two second fixing blocks 205 are fixedly connected to one side of the outer surface of the stop block 204. A first rotating shaft 206 is movably embedded between the inner walls of the two second fixing blocks 205. A support block 207 is fixedly sleeved on the outer surface of the first rotating shaft 206. The outer surfaces of both first fixing blocks 201 are fixedly connected to the inner wall of the pipe 1. The stop block 204... The outer surface is in contact with the inner wall of the pipe 1. The inner wall of the pipe 1 is fixedly connected to a slide rail 208. A spring 209 is provided on the inner wall of the slide rail 208. One end of the spring 209 is fixedly connected to the inner wall of the slide rail 208, and the other end of the spring 209 is fixedly connected to the outer surface of the support block 207. The outer surface of the support block 207 is slidably connected to the inner wall of the slide rail 208. The outer surfaces of the two first fixed blocks 201 are fixedly connected to the second rotating shafts 210. The outer surfaces of the two second rotating shafts 210 are respectively movably embedded in the opposite outer surfaces of the stop block 204. The inner wall of the pipe 1 is movably embedded with a first fixed shaft 3. The outer surface of the first fixed shaft 3 is fixedly sleeved with a first counting gear 4. One end of the first fixed shaft 3 is fixedly connected to a third fixed block 5.

[0028] The overall effect of Embodiment 1 is as follows: When a high-precision rotary vane water meter is in use, if water is flowing in pipe 1, and the water volume is small and the flow is slow, the water will be blocked by the baffle 204 on the other side of the outer surface of the baffle 204. When the water accumulates to a certain extent on the other side of the baffle 204, the pressure of the water on the baffle 204 will gradually increase. When the water level is close to the top of the baffle 204, the water pressure will push the baffle 204 to move. The baffle 204 will drive the sliding shaft 203 to slide along the inside of the groove 202. At the same time, the outer surface of the second rotating shaft 210 will rotate along the inner wall of the baffle 204. When the baffle 204 moves, it will drive the support block 207 to move. When 207 moves, one end of the support block 207 drives the outer surface of the first rotating shaft 206 to rotate along the inner wall of the second fixed block 205. At the same time, the other end of the support block 207 slides along the inner wall of the slide rail 208, squeezing the spring 209. At this time, due to the water pressure, the stop block 204 changes from a nearly vertical state to a nearly horizontal state. The obstruction of the stop block 204 to the water suddenly decreases, and the water flow rate increases. The water passes through the filter screen 8 and enters the interior of the impeller disk 7, causing the impeller 6 to rotate. When the impeller 6 rotates, it drives the third fixed block 5 to rotate. When the third fixed block 5 rotates, it drives the first counting gear 4 to rotate. When the first counting gear 4 rotates once, the outer surface of the first counting gear 4 meshes with the second counting gear 10, thereby... The second counting gear 10 rotates one notch. When the second counting gear 10 rotates one revolution, it engages with the outer surface of the third counting gear 12, causing the third counting gear 12 to rotate one notch. When the water volume decreases, the water pressure on the stop block 204 decreases, and the compressive force on the spring 209 decreases. Therefore, the spring 209 pushes the support block 207 to move. The outer surface of the support block 207 slides along the inner wall of the slide rail 208. Simultaneously, as the support block 207 moves, it causes the outer surface of the first rotating shaft 206 to rotate along the inner wall of the second fixed block 205. At the same time, the support block 207 causes the stop block 204 to move, and the stop block 204 causes the slide shaft 203 to rotate along the groove 202. The water flow is slid along the inner wall until the baffle 204 is nearly vertical. The water usage is then observed by monitoring the rotation angles of the second fixed shaft 9 and the third fixed shaft 11 on the outer surface of the pipe 1. This device uses a limiting component 2 to block the water flow. When the water volume accumulates to a certain level, the baffle 204 is tilted towards the filter screen 8. Therefore, when the water pressure accumulates to a certain level, the water pressure will cause the baffle 204 to change from a nearly vertical state to a nearly horizontal state. At this point, the water volume has accumulated significantly, and when the baffle 204 changes to a nearly horizontal state, the water resistance suddenly decreases, resulting in a faster water speed. This causes the impeller 6 to rotate, which in turn drives the first counting gear 4 to rotate.This solves the problem that when the water flow rate is too slow or the water volume is low, the impeller 6 cannot be driven to rotate, thus reducing the measurement accuracy of the rotary vane water meter and causing inaccurate meter readings.

[0029] Example 2: As Figures 1-9 As shown, an impeller 6 is fixedly sleeved on the outer surface of the third fixed block 5, an impeller disk 7 is movably connected to the inner wall of the third fixed block 5, a water filter screen 8 is fixedly connected to the outer surface of the impeller disk 7, a second fixed shaft 9 is movably embedded in the inner wall of the pipe 1, a second counting gear 10 is fixedly sleeved on the outer surface of the second fixed shaft 9, a third fixed shaft 11 is movably embedded in the inner wall of the pipe 1, and a third counting gear 12 is fixedly sleeved on the outer surface of the third fixed shaft 11.

[0030] The effect achieved by the entire embodiment 2 is that when a high-precision rotary vane water meter is in use, when water flows from the baffle 204, the water flows through the outer surface of the filter screen 8 and flows through the holes between the filter screens 8, thereby driving the impeller 6 to rotate. The filter screen 8 intercepts impurities contained in the water outside the filter screen 8, thereby preventing impurities from damaging the outer surface of the impeller 6 as the water flows, thus reducing the wear of impurities in the water on the impeller 6 inside the filter screen 8, thereby reducing the cost of maintenance and replacement parts.

[0031] Working Principle: In use, water in a high-precision rotary vane water meter is blocked by the stop 204 on its other outer surface. When the water accumulates to a certain level on the other outer surface of the stop 204, the pressure of the water on the stop 204 gradually increases. At this time, the water pressure pushes the stop 204 to move, which in turn drives the support block 207 to move. One end of the support block 207 drives the outer surface of the first rotating shaft 206 to rotate along the inner wall of the second fixed block 205, while the other end of the support block 207 slides along the inner wall of the slide rail 208, compressing the spring 209. At this time, the stop 204 changes from a nearly vertical state to a nearly horizontal state, and the obstruction of the stop 204 on the water suddenly decreases, increasing the water flow rate. The water then passes through the filter screen 8 and enters the impeller disk 7, causing the impeller 6 to rotate. The impurities in the water are intercepted outside the filter screen 8, thus preventing them from damaging the outer surface of the impeller 6 as the water flows. When the impeller 6 rotates, it drives the first counting gear 4 to rotate. When the first counting gear 4 rotates once, it drives the second counting gear 10 to rotate one division. When the second counting gear 10 rotates once, it drives the third counting gear 12 to rotate one division. This device uses a limiting component 2 to block the water flow. Therefore, when the water pressure accumulates to a certain level, the water pressure will drive the stop block 204 from a near-vertical state to a near-horizontal state. At this time, the water volume and water speed will drive the impeller 6 to rotate. When the impeller 6 rotates, it drives the first counting gear 4 to rotate, thereby improving the measurement accuracy of the rotary vane water meter and ensuring the accuracy of the rotary vane water meter measurement.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
