Description

Technical Field

[0001] This invention belongs to the field of rotary vane water meter technology, specifically a rotary vane water meter with an anti-clogging and self-cleaning structure. Background Technology

[0002] A water meter is a metering device used to measure the volume of water flowing through a pipe. It is generally divided into two main categories: volumetric and velocity. It is widely used in residential buildings, commercial buildings, and industrial facilities to ensure accurate measurement of water consumption for billing and water resource management. The working principle of a water meter is that when water flows through the meter, it drives the internal float or blades to rotate. The rotation speed is proportional to the water flow rate. The rotation is converted into a digital display through a mechanical transmission device, thereby recording the cumulative water consumption.

[0003] In existing technologies, rotary vane water meters are often used in situations where small flow rates need to be measured, such as in residential areas or factories. A rotary vane water meter mainly consists of a casing, a filter screen, an impeller box, an impeller, an impeller shaft, an adjusting plate, a dial, a pointer or digit wheel, and a transmission gear. Its working principle is that water flows into the casing from the inlet, is filtered by the filter screen, and then enters the impeller box to impact the impeller and make it rotate. The impeller speed is proportional to the water flow speed. The rotation is transmitted to the indicating mechanism through the impeller shaft and gear reduction mechanism, and the cumulative water consumption is recorded in a decimal cumulative manner.

[0004] In the aforementioned rotary vane water meter, the filter screen fitted outside the impeller is its main filtration module. However, with prolonged use, scale and impurities will continuously accumulate on the surface of the filter screen, causing the pores of the filter screen to shrink. This, in turn, obstructs the water flow from the water meter, resulting in a decrease in the water flow and pressure at the user's end, affecting the customer's normal use.

[0005] Therefore, the present invention provides a rotary vane water meter with an anti-clogging and self-cleaning structure. Summary of the Invention

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 8As shown in the figure, a rotary vane water meter with an anti-clogging self-cleaning structure according to an embodiment of the present invention includes a housing 1; an inlet pipe 2 and an outlet pipe 3 are respectively fixedly connected to the side surface of the housing 1; the inlet pipe 2 and the outlet pipe 3 are respectively located on both sides of the housing 1, and the inlet pipe 2 is lower than the outlet pipe 3; an impeller disk 4 is provided inside the housing 1; a filter screen 5 is sleeved on the outside of the impeller disk 4; an impeller 6 is rotatably connected inside the impeller disk 4; a gear counter 7 is installed on the top surface of the impeller 6; a top cover 8 is threadedly connected to the top of the housing 1; and the bottom of the housing 1... A cleaning chamber 9 is threadedly connected and communicates with the interior of the outer casing 1. A drive column 10 is rotatably connected to the bottom surface inside the cleaning chamber 9, and the drive column 10 is connected to an external micro motor via a magnetic coupling. A pair of connecting rods 11 are mounted on the surface of the drive column 10, with the two connecting rods 11 located on opposite sides of the drive column 10. A support rod 12 is mounted on the end of each connecting rod 11 away from the drive column 10. Evenly spaced brushes 13 are mounted on the side surface of the connecting rods 11, and the brushes 13 are located on the bottom surface of the filter screen 5. During operation, in order to clean the surface of the filter screen 5... To prevent scale buildup and ensure normal water flow in outlet pipe 3, this invention can be used. First, the inlet pipe 2 and outlet pipe 3 of this invention need to be correctly installed on the water supply pipe, ensuring water enters from inlet pipe 2 and exits from outlet pipe. Simultaneously, the main valve of the pipeline must be located near inlet pipe 2. During normal use, water enters the housing 1 through inlet pipe 2, passes through filter screen 5 and impeller 6, impacting impeller 6 and causing it to rotate. The rotating impeller 6 then drives gear counter 7, thereby measuring water usage. Then, when this invention is implemented… For example, after prolonged use, scale will accumulate on the surface of the filter screen. At this time, the user needs to first close the main valve near the water inlet pipe 2, then start the external micro motor, which will drive the drive column 10 to rotate through the magnetic coupling. Then the drive column 10 will drive the two support rods 12 and the connecting rod 11 to rotate synchronously, so that the brush 13 on the surface of the connecting rod 11 can continuously scrape the surface of the filter screen 5, thereby cleaning the scale on the surface of the filter screen 5, thus preventing the water flow from being blocked due to scale blockage and thus affecting the user's normal use.

[0035] In one embodiment, such as Figures 7 to 8As shown, the two connecting rods 11 are fixedly connected to a slip ring 14 at one end near the drive column 10; the slip ring 14 is slidably connected to the drive column 10; traction rods 15 are fixedly connected to both sides of the slip ring 14 between the two connecting rods 11; a magnetic block 16 is fixedly connected to the end of the traction rod 15 away from the slip ring 14; a receiving ring 17 is sleeved on the outer side of the cleaning chamber 9; drive plates 18 are slidably connected to both sides of the receiving ring 17, and both drive plates 18 are connected to the output end of an external micro motor; the drive plates 18 and the receiving ring 17 are fixed together by locking screws; a rotating ring 19 is rotatably connected to the top surface of the receiving ring 17; a magnetic block 20 is embedded in the inner side of the rotating ring 19 at the corresponding position of the magnetic block 16, and the ends of the magnetic block 16 and the magnetic block 20 that are close to each other attract each other; during operation, when it is necessary to clean the bottom surface of the filter screen 5, the user needs to rotate the rotating ring 19 on the top surface of the receiving ring 17, so that the rotating ring 19... The magnetic block 20 on the surface is aligned with the magnetic block 20 at the end of the traction rod 15. When the user slides the receiving ring 17 and the rotating ring 19 upwards, the rotating ring 19 will drive the traction rod 15 to rise through the attraction between the magnetic block 20 and the magnetic block 16. The rising traction rod 15 will then drive the connecting rod 11 and the support rod 12 to rise through the slip ring 14, so that the brush 13 can be tightly attached to the bottom surface of the filter screen 5. This allows the brush 13 to better clean the filter screen 5 when the drive column 10 drives the brush 13 to rotate, thereby improving the cleaning effect of the filter screen 5. At the same time, when the external micro motor drives the drive column 10 to rotate, it will also drive the receiving ring 17 to rotate synchronously through the drive plate 18, so that the rotating ring 19 and the traction rod 15 inside the cleaning chamber 9 can rotate synchronously, thus ensuring that the magnetic block 16 and the magnetic block 20 can always maintain their corresponding positions, and thus ensuring that the brush 13 can always be attached to the bottom surface of the filter screen 5 during the rotation.

[0036] In one embodiment, such as Figures 7 to 8As shown, a rotating rod 21 is fixedly connected to the end of the support rod 12 away from the drive column 10, and the rotating rod 21 is rotatably connected to the connecting rod 11; a gear 22 is fixedly connected to the surface of the rotating rod 21; a toothed plate 23 is meshed with the surface of the gear 22; a support plate 24 is slidably connected to the bottom of the slip ring 14 on the surface of the drive column 10; a pair of sliding rods 25 are fixedly connected to the top surface of the support plate 24, and the sliding rods 25 are slidably connected to the slip ring 14; the diameter of the top of the sliding rod 25 is larger than its bottom diameter; the two toothed plates 23 are respectively fixedly connected to... At both ends of the support plate 24, magnetic blocks 26 are fixedly connected to each other, and the ends of magnetic blocks 26 and magnetic blocks 20 that are close to each other attract each other. During operation, when it is necessary to clean the side surface of the filter screen 5, the user needs to rotate the rotating ring 19 on the top surface of the receiving ring 17 and press the drive plate 18, so that the magnetic blocks 20 on the surface of the rotating ring 19 are aligned with the magnetic blocks 26 at the end of the support plate 24. When the user lifts the receiving ring 17, the rotating ring 19 will drive the magnetic blocks 26 to rise through the magnetic blocks 20. This causes the support plate 24 to move toward the connecting rod 11, and the slide rod 25 to slide relative to the slip ring 14. During the movement of the support plate 24 toward the connecting rod 11, the toothed plate 23 at the end of the support plate 24 will drive the rotating rod 21 to rotate 90 degrees through the gear 22, thereby causing the support rod 12 to rotate from a horizontal state to a vertical state. Then, the support plate 24, the connecting rod 11, and the support rod 12 will rise. At this time, the brush 13 will be inserted between the filter screen 5 and the inner wall of the outer shell 1. Subsequently, the external micro motor will drive the drive column 1. When the drive column 10 rotates, it drives the connecting rod 11 and the support rod 12 to rotate through the slip ring 14, which makes the brush 13 rotate around the side wall of the filter screen, thereby cleaning the side wall of the filter screen and further improving the cleaning effect of the filter screen. At the same time, when the support plate 24 and the connecting rod 11 move away from each other, the slide rod 25 can limit the distance between them, so that when the second magnetic block 20 and the first magnetic block 16 are attracted, the support rod 12 can be kept horizontal, avoiding the support rod 12 from tilting downward due to the pressure of the bottom of the filter screen.

[0037] like Figures 4 to 6 As shown, the top surface of the receiving ring 17 is inlaid with two pairs of metal plates 27; the two pairs of metal plates 27 are respectively positioned opposite to the magnetic block 16 and the magnetic block 20, and the metal plates 27 are made of magnetizable metal; during operation, when the user needs to rotate the rotating ring 19 so that the magnetic block 20 on its surface can be attracted to the magnetic block 16 or the magnetic block 26, the user can determine whether the magnetic block 20 is attracted to the magnetic block 16 or the magnetic block 26 based on the two pairs of metal plates 27 on the surface of the receiving ring 17. At the same time, the magnetic block 20 will also attract to the metal plates 27, thereby fixing the position of the rotating ring 19 and preventing the receiving ring 17 from driving the rotating ring 19 to rotate, causing relative sliding between the rotating ring 19 and the receiving ring 17, which would result in asynchronous rotation of the two.

[0038] like Figure 8 As shown, a connecting plate 28 is fixedly connected to the side of the support plate 24 near the rotating rod 21; a pair of spring pieces 29 are fixedly connected to the top surface of the connecting plate 28 and the side away from the support plate 24; a limiting block 30 is fixedly connected to the end of the rotating rod 21 near the spring piece 29, and the end face of the limiting block 30 is square; during operation, when the rotating rod 21 rotates, it will drive the limiting block 30 to rotate synchronously. Since the end face of the limiting block 30 is square, and the spring piece 29 on the surface of the connecting plate 28 is exactly in contact with the two sides of the limiting block 30, the limiting block 30 is restricted, so that it can only rotate 90 degrees each time, and thus also synchronously restricts the rotation of the rotating rod 21, so that the rotation can only drive the support rod 12 to rotate to the horizontal and vertical states.

[0039] like Figure 5 , Figure 8 and Figure 9 As shown, a sleeve 31 is rotatably connected to the outer side of the receiving ring 17; the brush 13 is fixedly connected to the outer side of the sleeve 31; a gear 32 is fixedly connected to the outer side of the sleeve 31 away from the rotating rod 21; a toothed ring 33 is fixedly connected to the inner wall of the cleaning chamber 9, and the gear 32 can mesh with the toothed ring 33; during operation, when the brush 13 is cleaning the side surface of the filter screen 5, the gear 32 on the surface of the sleeve 31 will mesh with the toothed ring 33. At this time, when the drive column 10 drives the connecting rod 11 and the support rod 12 to rotate, the support rod 12 will drive the sleeve 31 to rotate around the outer side of the filter screen 5. Since the gear 32 on the surface of the sleeve 31 meshes with the toothed ring 33, the sleeve 31 will also rotate on the surface of the support rod 12 during the rotation, thereby further improving the cleaning effect of the brush 13 on the surface of the sleeve 31 on the filter screen 5.

[0040] like Figure 10 As shown, a support ring 34 is fixedly connected to the inner wall of the outer shell 1 at the corresponding position on the top of the impeller disk 4; the protruding part of the impeller 6 and the top of the filter screen 5 both rest on the top of the support ring 34; an annular groove 35 is opened on the bottom surface of the support ring 34, and the width of the groove opening of the annular groove 35 is greater than the width of its bottom; a limiting rod 36 is fixedly connected to the end of the support rod 12 away from the rotating rod 21, and the limiting rod 36 is adapted to the bottom of the annular groove 35; during operation, when the support rod 12 is in a vertical state and gradually rises to the side surface of the filter screen 5, the limiting rod 36 at the end of the support rod 12 will be inserted into the limiting groove, thereby restricting the position of the support rod 12 and ensuring that the gear 2 32 on the surface of the sleeve 31 can always maintain meshing with the gear ring 33, preventing the gear 2 32 and the gear ring 33 from always maintaining meshing during the rotation of the sleeve 31 around the filter screen 5.

[0041] like Figures 4 to 5As shown, a pair of receiving boxes are fixedly connected to the top of the cleaning chamber 9, and the receiving boxes are in communication with the interior of the cleaning chamber 9; a blocking plate is slidably connected inside the receiving box; a groove 39 is opened on the side of the two blocking plates that are close to each other, and both grooves 39 are adapted to the drive column 10; a screw 40 is rotatably connected on the side of the two blocking plates that are far from each other, and the screw 40 is threadedly connected to the receiving box; during operation, when the brush 13 is not needed to clean the filter screen 5, the user can lower the brush 13 into the cleaning chamber 9, and then the user screws the screw 40, which pushes the blocking plate toward the drive rod, and finally makes the groove 39 fit onto the surface of the drive rod, thereby separating the cleaning chamber 9 and the outer shell 1 by the blocking plate, thus not changing the internal volume of the outer shell 1, ensuring that the water entering from the water inlet pipe 2 can correctly impact the impeller 6 in the impeller 6 box, thereby ensuring the counting accuracy of the gear counter 7.

[0042] like Figure 4 , Figure 5 and Figure 11 As shown, each of the two screws 40 has a connecting post 41 fixedly connected to its opposite end, and both ends of the screws 40 are set as regular hexagonal prisms. A sleeve 42 is inserted into the surface of the connecting post 41, and the inner side of the sleeve 42 is adapted to the end of the screw rod away from the end plate. A mounting plate 43 is rotatably connected to the surface of the sleeve 42. A synchronizing rod 44 is provided on the side of the mounting plate 43 away from the sleeve 42, and the synchronizing rod 44 drives the sleeve 42 to rotate through the transmission assembly. During operation, when the user needs to rotate the screw 40, the user can first rotate the synchronizing rod 44, and the synchronizing rod 44 will then drive the sleeves 42 at the ends of the two mounting plates 43 to rotate synchronously through the transmission assembly. Finally, the two sleeves 42 drive the screw 40 to rotate synchronously, thereby enabling the two end plates to move synchronously, thus avoiding one end plate from contacting the drive post 10, which would cause the drive post 10 to be subjected to force on one side and thus deform the drive post 10.

[0043] like Figure 11As shown, the transmission assembly includes a pair of gears 45, which are respectively fixedly connected to both ends of the synchronizing rod 44; a gear set 46 is rotatably connected to the surface of the mounting plate 43; the gears 45 can mesh with the gear set 46, and the gear set 46 meshes with the sleeve 42; sockets 47 are fixedly connected to both sides of the cleaning chamber 9; a plug 48 is rotatably connected to the surface of the synchronizing rod 44, and the plug 48 is adapted to the socket 47; the socket 47 is made of magnet, and the plug 48 is made of magnetizable metal; during operation, when the user needs to synchronously rotate the two screws 40 through the synchronizing rod 44, the sleeve 42 needs to be slid first. 2. Remove the sleeve 42 from the end of the screw 40, then rotate the sleeve 42 and the mounting plate 43 so that the mounting plate 43 faces to your side. Then, re-attach the sleeve 42 to the end face of the screw 40. Next, insert the insert rod 48 into the socket 47. Then, mesh the gear set 46 on the surface of the mounting plate 43 with the gear 3 45 on the surface of the synchronizing rod 44. Thus, the synchronizing rod 44 can drive the two sleeves 42 to rotate synchronously through the gear 3 45 and the gear set 46. Since the sockets 47 are fixedly connected to both sides of the cleaning chamber 9, the user can install the synchronizing rod 44 on one side of the cleaning chamber 9 according to the actual situation for their own convenience.

[0044] During operation, to clean the scale accumulated on the surface of the filter screen 5 and ensure normal water flow in the outlet pipe 3, this embodiment of the invention can be used. First, the inlet pipe 2 and outlet pipe 3 of this embodiment need to be correctly installed on the water supply pipe, ensuring that water flows in from the inlet pipe 2 and out from the outlet pipe. Simultaneously, the main valve of the pipeline must be located near the inlet pipe 2. During normal use, water flows into the housing 1 through the inlet pipe 2, passes through the filter screen 5 and impeller 6, and impacts the impeller 6, causing it to rotate. The rotating impeller 6 then drives the gear counter 7 to rotate, thereby measuring the water consumption. After prolonged use, scale will accumulate on the surface of the filter screen. At this time, the user needs to first close the main valve near the water inlet pipe 2, then start the external micro motor, which will drive the drive column 10 to rotate through the magnetic coupling. The drive column 10 will then drive the two support rods 12 and the connecting rod 11 to rotate synchronously, so that the brush 13 on the surface of the connecting rod 11 can continuously scrape the surface of the filter screen 5, thereby cleaning the scale on the surface of the filter screen 5. This will prevent the water flow from being blocked by scale and thus avoid affecting the user's normal use.

[0045] When cleaning the bottom surface of the filter screen 5 is required, the user needs to rotate the rotating ring 19 on the top surface of the receiving ring 17 so that the magnetic block 20 on the surface of the rotating ring 19 is aligned with the magnetic block 20 at the end of the traction rod 15. At this time, the user slides the receiving ring 17 and the rotating ring 19 upwards. The rotating ring 19 will then drive the traction rod 15 to rise through the attraction between the magnetic block 20 and the magnetic block 16. The rising traction rod 15 will then drive the connecting rod 11 and the support rod 12 to rise through the slip ring 14, thereby allowing the brush 13 to adhere tightly to the bottom of the filter screen 5. This allows the drive column 10 to rotate the brush 13, enabling the brush 13 to better clean the filter screen 5, thereby improving the cleaning effect on the filter screen 5. At the same time, when the external micro motor drives the drive column 10 to rotate, it will also drive the receiving ring 17 to rotate synchronously through the drive plate 18, so that the rotating ring 19 and the traction rod 15 inside the cleaning chamber 9 can rotate synchronously, thereby ensuring that the magnetic block 16 and the magnetic block 20 can always maintain their corresponding positions, and thus ensuring that the brush 13 can always stick to the bottom surface of the filter screen 5 during the rotation process.

[0046] When cleaning the side surface of the filter screen 5 is required, the user needs to rotate the rotating ring 19 on the top surface of the receiving ring 17 and press the drive plate 18, so that the magnetic block 20 on the surface of the rotating ring 19 is aligned with the magnetic block 26 at the end of the support plate 24. When the user lifts the receiving ring 17, the rotating ring 19 will drive the magnetic block 26 to rise through the magnetic block 20, thereby causing the support plate 24 to move towards the connecting rod 11, and causing the slide rod 25 to slide relative to the slide ring 14. During the movement of the support plate 24 towards the connecting rod 11, the toothed plate 23 at the end of the support plate 24 will drive the rotating rod 21 to rotate 90 degrees through the gear 1 22, thereby causing the support rod 12 to rotate from a horizontal state to a vertical state, and then... The support plate 24, connecting rod 11, and support rod 12 are raised, at which point the brush 13 will be inserted between the filter screen 5 and the inner wall of the outer casing 1. Then, the external micro motor drives the drive column 10 to rotate, and the drive column 10 drives the connecting rod 11 and support rod 12 to rotate through the slip ring 14, so that the brush 13 can rotate around the side wall of the filter screen, thereby cleaning the side wall of the filter screen and further improving the cleaning effect of the filter screen. At the same time, when the support plate 24 and the connecting rod 11 move away from each other, the slide rod 25 can limit the distance between them, so that when the second magnetic block 20 and the first magnetic block 16 are attracted, the support rod 12 can be kept horizontal, avoiding the support rod 12 from tilting downward due to the pressure of the bottom of the filter screen.

[0047] When the user needs to rotate the rotating ring 19 so that the second magnetic block 20 on its surface can be attracted to the first magnetic block 16 or the third magnetic block 26, the user can determine whether the second magnetic block 20 is attracted to the first magnetic block 16 or the third magnetic block 26 based on the two pairs of metal plates 27 on the surface of the receiving ring 17. At the same time, the second magnetic block 20 will also attract to the metal plates 27, thereby fixing the position of the rotating ring 19 and preventing the receiving ring 17 from driving the rotating ring 19 to rotate. This would prevent relative sliding between the rotating ring 19 and the receiving ring 17, which would cause the two to rotate asynchronously.

[0048] When the rotating rod 21 rotates, it will drive the limiting block 30 to rotate synchronously. Since the end face of the limiting block 30 is square, and the spring piece 29 on the surface of the connecting plate 28 is exactly in contact with the two sides of the limiting block 30, the limiting block 30 is restricted, so that it can only rotate 90 degrees at a time, and thus also restricts the rotation of the rotating rod 21, so that the rotation can only drive the support rod 12 to rotate to the horizontal and vertical states.

[0049] When the brush 13 is cleaning the side surface of the filter screen 5, the gear 32 on the surface of the sleeve 31 will mesh with the toothed ring 33. At this time, when the drive column 10 drives the connecting rod 11 and the support rod 12 to rotate, the support rod 12 will drive the sleeve 31 to rotate around the outside of the filter screen 5. Since the gear 32 on the surface of the sleeve 31 meshes with the toothed ring 33, the sleeve 31 will also rotate on the surface of the support rod 12 during the rotation, thereby further improving the cleaning effect of the brush 13 on the surface of the sleeve 31 on the filter screen 5.

[0050] When the support rod 12 is in a vertical position and gradually rises to the side surface of the filter screen 5, the limiting rod 36 at the end of the support rod 12 will be inserted into the limiting groove, thereby limiting the position of the support rod 12 and ensuring that the gear 32 on the surface of the sleeve 31 can always be engaged with the toothed ring 33, so that the gear 32 and the toothed ring 33 can always be engaged during the rotation of the sleeve 31 around the filter screen 5.

[0051] When the brush 13 is not needed to clean the filter screen 5, the user can lower the brush 13 into the cleaning chamber 9, and then the user can turn the screw 40, which will push the plug plate towards the drive rod, and finally make the groove 39 fit onto the surface of the drive rod. This will separate the cleaning chamber 9 from the outer shell 1, thus not changing the internal volume of the outer shell 1, ensuring that the water entering from the water inlet pipe 2 can correctly impact the impeller 6 in the impeller 6 box, thereby ensuring the counting accuracy of the gear counter 7.

[0052] When the user needs to rotate the screw 40, the user can first rotate the synchronizing rod 44, which will then drive the sleeves 42 at the ends of the two mounting plates 43 to rotate synchronously through the transmission assembly. Finally, the two sleeves 42 will drive the screw 40 to rotate synchronously, thereby enabling the two blocking plates to move synchronously. This avoids the blocking plates on one side from contacting the drive column 10, which would cause the drive column 10 to be subjected to force on one side and thus cause the drive column 10 to deform.

[0053] When the user needs to rotate the two screws 40 synchronously via the synchronizing rod 44, the sleeve 42 must first be slid so that it is no longer fitted onto the end of the screw 40. Then, the sleeve 42 and the mounting plate 43 are rotated so that the mounting plate 43 faces the user. The sleeve 42 is then reattached to the end face of the screw 40. The insert rod 48 is then inserted into the socket 47. The gear set 46 on the surface of the mounting plate 43 is then engaged with the gear 3 45 on the surface of the synchronizing rod 44. Thus, the synchronizing rod 44 can drive the two sleeves 42 to rotate synchronously via the gear 3 45 and the gear set 46. Since the sockets 47 are fixedly connected to both sides of the cleaning chamber 9, the user can install the synchronizing rod 44 on one side of the cleaning chamber 9 according to the actual situation for their convenience.
