Description

Technical Field

[0001] This application relates to the field of water meter technology, and in particular to an explosion-proof water meter. Background Technology

[0002] Explosion-proof water meters are devices used to detect water consumption. They are a type of professional water meter designed to prevent damage caused by excessive water pressure during water use. They measure the flow rate of water through the meter by the rotation speed of a turbine, multiply the flow rate by the cross-sectional area through which the water flows to obtain the water consumption, and then display the result on the meter's display screen.

[0003] In the context of related technologies, explosion-proof water meters may burst under excessive water pressure due to increased forces on their walls. Furthermore, in cold winters, the increased volume of ice inside the meter can also increase pressure on its walls, potentially leading to bursting. Summary of the Invention

[0004] This application provides an explosion-proof water meter that can improve the technical problem in related technologies where excessive water pressure or water freezing inside the meter increases the pressure on the various walls of the meter, leading to the meter bursting.

[0005] This application provides an explosion-proof water meter, including:

[0006] A water meter housing, wherein the water meter housing has an accommodating space;

[0007] An adjustment mechanism is disposed within the accommodating space. The adjustment mechanism includes a partition member, which is adjustablely disposed within the accommodating space and divides the accommodating space into a first space and a second space, wherein the first space and the second space are not in communication.

[0008] A metering mechanism is adjustablely disposed within the first space, with one end of the metering mechanism abutting against the partition and the other end abutting against the inner top wall of the first space; the metering mechanism is used to measure the amount of water flowing through the first space.

[0009] A water meter information detection unit, wherein the water meter information detection unit is disposed in the first space or the second space, is used to detect the pressure or liquid flow rate in the first space; and

[0010] A control unit is disposed on the water meter housing. The control unit is electrically connected to the water meter information detection unit and the adjustment mechanism. It is used to control the adjustment mechanism according to the pressure or liquid flow rate in the first space detected by the water meter information detection unit, so that the adjustment mechanism adjusts the movement of the partition, thereby expanding or shrinking the first space. When the partition moves, it can drive at least a part of the metering mechanism to move, so that the metering mechanism can detect the amount of water flowing through the expanded or shrunken first space.

[0011] The technical solutions described in this application embodiment have at least the following technical effects:

[0012] The explosion-proof water meter provided in this application embodiment comprises a water meter housing with a accommodating space, an adjustment mechanism disposed in the accommodating space, a metering mechanism adjustablely disposed in a first space, a water meter information detection unit disposed in the accommodating space, and a control unit disposed in the water meter housing. The adjustment mechanism further includes a partition disposed in the accommodating space and dividing the accommodating space into a first space and a second space. The water meter information detection unit detects pressure information and flow velocity information reflecting the water flow conditions in the first space and sends them to the control unit. The control unit can process the received pressure information and flow velocity information to generate control information, and adjust the adjustment mechanism based on the generated control information to move the partition within the accommodating space, thereby expanding or shrinking the first space, thereby reducing the pressure of the liquid in the first space on the water meter housing. Thus, in winter, when the liquid inside the explosion-proof water meter freezes, the partition is adjusted to expand the first space, thereby reducing the pressure of the frozen liquid inside the water meter on the water meter housing, thereby preventing the frozen liquid inside the explosion-proof water meter from bursting open. When the water meter casing is subjected to excessive pressure due to the flow of liquid inside the water meter, the pressure on the water meter casing can be reduced by moving the partition to shrink the first space, thereby preventing the water meter from bursting. At the same time, by synchronously adjusting the metering mechanism and the partition, the metering mechanism can measure the amount of water flowing through the first space of different sizes.

[0013] In some embodiments, the adjustment mechanism further includes:

[0014] A driving component is disposed within the second space; the driving component is electrically connected to the control unit.

[0015] A gear, the gear being located within the second space, and the gear being connected to the power output end of the drive member;

[0016] A rack, located within the second space, meshing with the gear; the rack's direction of movement is perpendicular to the direction of movement of the separator; and

[0017] A linkage rod is located within the second space, with one end of the linkage rod hinged to one end of the rack and the other end of the linkage rod hinged to the separator.

[0018] The driving component is used to drive the gear to rotate forward or backward. The forward rotation of the gear can drive the rack to move away from the connecting rod, so that the rack drives the separator to move towards the second space through the connecting rod, thereby expanding the first space. The reverse rotation of the gear can drive the rack to move towards the connecting rod, so that the rack drives the separator to move away from the second space through the connecting rod, thereby shrinking the first space.

[0019] In some embodiments, the adjusting mechanism further includes a sealing ring, which is sleeved around the periphery of the separator so that the separator slides against the side wall of the water meter housing via the sealing ring.

[0020] In some embodiments, the adjusting mechanism further includes a rack limiting device disposed within the second space; the rack limiting device has a rack movement space, and the rack is movably disposed within the rack movement space.

[0021] In some embodiments, the measuring device includes:

[0022] A fixed axis is located at the center of the first space and is connected to the separator.

[0023] A first turbine, rotatably mounted on the fixed shaft, and having an installation space facing the bottom wall of the separator; and

[0024] The second turbine is rotatably mounted on the fixed shaft and movably mounted within the mounting space;

[0025] Specifically, when the separator moves toward the second space, the second turbine can move toward the second space simultaneously with the separator; when the separator moves away from the second space, the second turbine moves away from the second space simultaneously with the separator.

[0026] In some embodiments, the measuring mechanism further includes a fixing member rotatably disposed on one end of the fixed shaft; a fixing groove is provided on the inner wall of the hole of the second turbine for rotating with the fixed shaft, and the fixing member is at least partially located in the fixing groove.

[0027] In some embodiments, the fixing member includes a locking member and a thermal expansion layer, the thermal expansion layer being disposed on the side wall of the fixed shaft, and the locking member being disposed on the side wall of the thermal expansion layer; the side wall of the second turbine has a fixing groove, and the locking member is movable into the fixing groove; when the fixing member engages with the second turbine, the locking member is at least partially located within the fixing groove; at a temperature of 0 degrees Celsius, the thermal expansion layer contracts, causing the locking member to move out of the fixing groove.

[0028] In some embodiments, the water meter information detection unit includes:

[0029] A pressure sensor, disposed within the first space or the second space, electrically connected to the control unit, is used to detect the pressure within the first space; and

[0030] A flow rate sensor is disposed in the first space and electrically connected to the control unit. The flow rate sensor is used to detect the liquid flow rate in the first space.

[0031] In some embodiments, the control unit is configured to generate first control information when the pressure is higher than the maximum pressure of a preset pressure range and the liquid flow rate is 0. The first control information is configured to instruct the adjustment mechanism to adjust the separator to move toward the second space to expand the first space.

[0032] The control unit is used to generate second control information when the pressure information is higher than a preset pressure range and the liquid flow rate information is not 0. The second control information is used to instruct the adjustment mechanism to adjust the separator to move away from the second space to reduce the first space.

[0033] The control unit is used to generate third control information when the pressure information is within or below the preset pressure range and the liquid flow rate is 0 or not zero. The third control information is used to instruct the adjustment mechanism to adjust the separator to remain stationary so as to keep the size of the first space unchanged.

[0034] In some embodiments, the explosion-proof water meter further includes a filter device disposed at the water inlet, the filter device being used to filter the liquid passing through the water inlet. Attached Figure Description

[0056] An explosion-proof water meter is a device used to detect water consumption. It is designed to prevent the water meter from bursting due to excessive pressure from the liquid inside the meter during water use. It measures the flow rate of water through the meter by the rotation speed of the turbine, multiplies the flow rate by the cross-sectional area it passes through to obtain the water consumption, and then displays the result on the meter's display screen.

[0057] In related technologies, explosion-proof water meters may explode and disintegrate when the water pressure is too high, as the forces on the various walls of the water meter increase. If the pressure on the various walls exceeds the maximum pressure that the material used to make the water meter casing can withstand. Furthermore, in cold winters, the increased volume of ice inside the explosion-proof water meter will further increase the pressure on the various walls of the water meter. If the pressure on the various walls exceeds the maximum pressure that the material used to make the water meter casing can withstand, the water meter may also explode and disintegrate.

[0058] Based on this, in order to improve the problem of water meters in related technologies bursting and disintegrating under excessive water pressure or internal freezing, the embodiments of this application provide the following solutions.

[0059] Please refer to the following: Figure 1 and Figure 2 This application provides an explosion-proof water meter, which includes a water meter housing 10, an adjusting mechanism 20, a metering mechanism 30, a water meter information detection unit 40, and a control unit 50. Wherein:

[0060] The water meter housing 10 has a receiving space 100.

[0061] The adjustment mechanism 20 is disposed within the accommodating space 100. The adjustment mechanism 20 includes a separator 21, which is adjustablely disposed within the accommodating space 100 and divides the accommodating space 100 into a first space 101 and a second space 102. The first space 101 and the second space 102 are not connected.

[0062] The metering mechanism 30 is adjustablely disposed in the first space 101. One end of the metering mechanism 30 abuts against the partition 21, and the other end of the metering mechanism 30 abuts against the inner top wall of the first space 101. The metering mechanism 30 is used to measure the amount of water flowing through the first space 101.

[0063] The water meter information detection unit 40 is installed in the first space 101 or the second space 102 and is used to detect the pressure or liquid flow rate in the first space 101.

[0064] The control unit 50 is disposed on the water meter housing 10. The control unit 50 is electrically connected to the water meter information detection unit 40 and the adjustment mechanism 20. It is used to control the adjustment mechanism 20 according to the pressure or liquid flow rate in the first space 101 detected by the water meter information detection unit 40, so that the adjustment mechanism 20 adjusts the movement of the partition 21, thereby expanding or shrinking the first space 101. When the partition 21 moves, it can drive at least part of the metering mechanism 30 to move, so that the metering mechanism 30 can detect the amount of water flowing through the expanded or shrunken first space 101.

[0065] It is understood that the water meter housing 10 is a device for accommodating the regulating mechanism 20, the metering mechanism 30, the water meter information detection unit 40, and the control unit 50. The water meter housing 10 can be a cylindrical housing with a cylindrical accommodating space 100, a cuboid housing with a cylindrical accommodating space 100, etc.

[0066] The adjustment mechanism 20 is used to expand or shrink the first space 101. For example, the adjustment mechanism 20 can be configured as a gear and rack mechanism that cooperates with the partition 21, with one end of the rack 23 connected to the partition 21. The gear and rack mechanism drives the partition 21 to move toward the first space 101 to shrink the first space 101 or to move away from the first space 101 to expand the first space 101. Alternatively, the adjustment mechanism 20 can be configured as a small linear motor that cooperates with the partition 21, with the output end of the small linear motor connected to the partition 21. The small linear motor drives the partition 21 to move toward the first space 101 to shrink the first space 101 or to move away from the first space 101 to expand the first space 101.

[0067] The metering mechanism 30 is used to measure the amount of water flowing through the first space 101 before or after regulation; the metering mechanism 30 can be an adjustable turbine, flow sensor, etc.

[0068] The water meter information detection unit 40 is used to detect the pressure or fluid flow rate in the first space 101. The water meter information detection unit 40 can be a mechanical pressure sensor, a turbine flow meter, a piezoelectric pressure sensor, or an electromagnetic flow meter, etc.

[0069] The control unit 50 is a device for receiving pressure and flow rate information measured by the water meter information detection unit 40 and controlling the regulating mechanism 20. The control unit 50 can be a microcontroller (MCU), an embedded controller, etc. The partition 21 is used to divide the accommodating space 100 into a first space 101 and a second space 102 that are not interconnected. The partition 21 can be a cylindrical plate, a cylindrical shell, etc.

[0070] As can be seen from the above, the explosion-proof water meter provided in this application embodiment comprises a water meter housing 10 with a receiving space 100, an adjustment mechanism 20 disposed in the receiving space 100, a metering mechanism 30 adjustablely disposed in the first space 101, a water meter information detection unit 40 disposed in the receiving space 100, and a control unit 50 disposed in the water meter housing 10. The adjustment mechanism 20 further includes a partition 21 disposed in the receiving space 100 and dividing the receiving space 100 into a first space 101 and a second space 102. The water meter information detection unit 40 is used to detect pressure information and flow velocity information that reflect the water flow conditions in the first space 101. The pressure and flow rate information is received and sent to the control unit 50. The control unit 50 processes the received pressure and flow rate information to generate control information. Based on the generated control information, it adjusts the regulating mechanism 20 to move the separator 21 within the receiving space 100, thereby expanding or shrinking the first space 101. This reduces the pressure of the liquid in the first space 101 on the water meter housing 10. Furthermore, in winter, when the liquid inside the explosion-proof water meter freezes, adjusting the separator 21 to expand the first space 101 reduces the pressure of the frozen liquid on the water meter housing 10, preventing the explosion-proof water meter from bursting open. If the pressure on the water meter housing 10 is too high due to internal liquid flow, the pressure on the water meter housing 10 can be reduced by moving the separator 21 to shrink the first space 101, preventing the water meter from bursting. Simultaneously, by synchronously adjusting the metering mechanism 30 and the separator 21, the metering mechanism 30 can measure the amount of water flowing through the first space 101 of different sizes.

[0071] In some embodiments, please refer to the following: Figures 3 to 5 The adjusting mechanism 20 also includes a drive component 27, a gear 22, a rack 23, and a connecting rod 24. Wherein:

[0072] The drive unit 27 is disposed in the second space 102; the drive unit 27 is electrically connected to the control unit 50.

[0073] Gear 22 is located in the second space 102 and is connected to the power output end of drive member 27.

[0074] The rack 23 is located in the second space 102 and meshes with the gear 22; the direction of movement of the rack 23 is perpendicular to the direction of movement of the separator 21.

[0075] The linkage 24 is located in the second space 102, and one end of the linkage 24 is hinged to one end of the rack 23, while the other end of the linkage 24 is hinged to the separator 21.

[0076] The driving component 27 is used to drive the gear 22 to rotate forward or backward. When the gear 22 rotates forward, it can drive the rack 23 to move away from the connecting rod 24, so that the rack 23 drives the partition 21 to move toward the second space 102 through the connecting rod 24, thereby expanding the first space 101. When the gear 22 rotates backward, it can drive the rack 23 to move toward the connecting rod 24, so that the rack 23 drives the partition 21 to move away from the second space 102 through the connecting rod 24, thereby shrinking the first space 101.

[0077] It can be understood that the driving component 27 is a device used to drive the gear 22 to rotate, and the driving component 27 can be an electric motor, a small internal combustion engine, etc.

[0078] With this configuration, the drive component 27 rotates the gear 22, which in turn drives the connecting rod 24 via the rack 23. This, in turn, causes the connecting rod 24 to move the partition 21, thereby expanding or shrinking the first space 101. Compared to devices using a gear and rack mechanism with the partition 21, this solution allows for a wider adjustable range of the first space 101. Compared to devices using a linkage structure with the partition 21, this solution can accurately expand or shrink the first space 101.

[0079] Optionally, in some embodiments, please refer to Figures 1 to 5 The adjusting mechanism 20 also includes a sealing ring 25, which is sleeved around the periphery of the separator 21 so that the separator 21 slides against the side wall of the water meter housing 10 through the sealing ring 25.

[0080] With this configuration, by setting a sealing ring 25 between the separator 21 and the water meter housing 10, the first space 101 and the second space 102 are completely separated, thereby preventing liquid in the first space 101 from seeping into the second space 102 and affecting the normal operation of the explosion-proof water meter.

[0081] Optionally, please refer to Figures 1 to 5 The adjustment mechanism 20 also includes a rack limiting device 26, which is disposed in the second space 102; the rack limiting device 26 has a rack movement space 260, and the rack 23 is movably disposed in the rack movement space 260.

[0082] It can be understood that the rack and pinion movement limiting device 26 is a device used to support the rack and pinion 23 and limit the direction of movement of the rack and pinion 23. The rack and pinion movement limiting device 26 can be a cuboid shell, a cuboid guide rail, etc.

[0083] With this configuration, the rack 23 can stably mesh with the gear 22 by setting the rack movement limiting device 26. The rack movement limiting device 26 has a rack movement space 260. The rack movement space 260 has three side walls, one of which is away from the gear 22, and the other two are parallel to the bottom wall of the water meter housing 10. Setting the rack 23 in the rack movement space 260 allows the rack 23 to move in a direction perpendicular to the moving direction of the separator 21, thereby increasing the range of movement of the rack 23 and thus increasing the adjustment range of the adjustment mechanism 20.

[0084] For example, please refer to Figures 1 to 5 The metering mechanism 30 includes a fixed shaft 31, a first turbine 32, and a second turbine 33. Wherein:

[0085] The fixed axis 31 is located at the center of the first space 101 and is connected to the separator 21.

[0086] The first turbine 32 is rotatably mounted on the fixed shaft 31, and the first turbine 32 has an installation space 320 facing the bottom wall of the separator 21.

[0087] The second turbine 33 is rotatably mounted on the fixed shaft 31 and is movably mounted within the mounting space 320.

[0088] Specifically, when the separator 21 moves toward the second space 102, the second turbine 33 can move toward the second space 102 along with the separator 21; when the separator 21 moves away from the second space 102, the second turbine 33 moves away from the second space 102 along with the separator 21.

[0089] It is understood that the cross-section of the installation space 320 can accommodate the cross-section of the second turbine 33. The first turbine 32 and the second turbine 33 together constitute a measuring mechanism for measuring the amount of water passing through the first space 101; the first turbine 32 and the second turbine 33 can be two rotating impellers combined together, and the combined rotating impellers can be height adjusted. The water flow in the first space 101 drives the measuring mechanism to rotate together, and the rotating shaft of the measuring mechanism 30 is connected to the gear of the water meter display.

[0090] With this configuration, the metering mechanism 30 consists of a rotatable but immovable first turbine 32, a fixed shaft 31 fixedly connected to the separator 21, and a second turbine 33 that rotates around the fixed shaft 31 and moves together with it. The movement of the separator 21 can drive the fixed shaft 31 and the second turbine 33 to move together, so that the second turbine 33 can move within the installation space 320. Compared with conventional metering units that cannot change the size of the turbine, the above scheme allows the metering mechanism 30, which is composed of the first turbine 32, the fixed shaft 31, and the second turbine 33, to change its metering range as the separator 21 moves, and the metering range is always equal to the first space 101. This allows the metering mechanism 30 to measure the flow rate through the first space 101 of different sizes, so that the metering mechanism 30 can maintain the metering function of the explosion-proof water meter even when the pressure on the water meter housing 10 is adjusted.

[0091] In some embodiments, please refer to Figure 2 and Figure 3 The measuring mechanism 30 also includes a fixing member 34, which is rotatably mounted on the fixed shaft 31; a fixing groove 330 is provided on the inner wall of the hole of the second turbine 33 for rotating with the fixed shaft 31, and the fixing member 34 is at least partially located in the fixing groove 330.

[0092] It can be understood that the fixing member 34 is a device used to enable the second turbine 33 to move together with the fixed shaft 31 without affecting the rotation. For example, the fixing member 34 can be a rotary bearing with a fixing body. The fixing body cooperates with the fixed mating groove 330 to fix the rotary bearing to the second turbine 33. The movement of the rotary bearing drives the second turbine 33 to move. For another example, the fixing member 34 can be a three-dimensional ring with a fixing body. The fixed shaft 31 is configured such that the radius of a section of the cylinder is smaller than the radius of the cylinders at both ends. The inner diameter of the three-dimensional ring matches the radius of the small radius cylinder. The three-dimensional ring is installed at the small radius cylinder so that the separator 21 can drive the three-dimensional ring to move without affecting the rotation.

[0093] With this configuration, the second turbine 33 is mounted on the fixed shaft 31 by the fixing member 34. The fixed shaft 31 drives the second turbine 33 to move through the fixing member 34 without affecting the rotation of the second turbine 33. Compared with mounting the second turbine 33 on the fixed shaft 31, the above solution can provide power for the movement of the second turbine 33, avoiding insufficient power that could cause it to jam and not move with the separator 21, thus affecting the metering function of the explosion-proof water meter.

[0094] Optionally, in some embodiments, please refer to Figures 1 to 5 The water meter information detection unit 40 includes a pressure sensor 41 and a flow rate sensor 42. Wherein:

[0095] The pressure sensor 41 is disposed in the first space 101 or the second space 102. The pressure sensor 41 is electrically connected to the control unit 50 and is used to detect the pressure in the first space 101.

[0096] The flow rate sensor 42 is disposed in the first space 101 and is electrically connected to the control unit 50. The flow rate sensor 42 is used to detect the liquid flow rate in the first space 101.

[0097] With this configuration, by setting up pressure sensor 41 and flow rate sensor 42 to measure the pressure and flow rate of the liquid in the first space 101, the pressure of the liquid on the water meter housing 10 and the liquid flow rate can be digitally transmitted to the control unit 50.

[0098] Optionally, please refer to Figures 1 to 5 The fixing member 34 includes a locking member 341 and a thermal expansion layer 342. The thermal expansion layer 342 is disposed on the side wall of the fixed shaft 31, and the locking member 341 is disposed on the side wall of the thermal expansion layer 342. The side wall of the second turbine 33 is provided with a fixing groove 330, and the locking member 341 can move into the fixing groove. When the fixing member 34 and the second turbine 33 are engaged, the locking member 341 is at least partially located in the fixing groove 330. When the temperature is 0 degrees, the thermal expansion layer 330 contracts, causing the locking member 341 to move out of the fixing groove 330.

[0099] It is understood that the locking component 341 is a component used to fix the second turbine 33 to the fixed shaft 31; the locking component 341 can be a block or a column, etc. The thermal expansion layer 342 is a component used to push the locking component 341; the thermal expansion layer 342 can be a polyethylene ring or a polypropylene ring.

[0100] With this configuration, when the internal liquid temperature is above 0 degrees Celsius, the thermal expansion layer 342 expands, driving the locking member 341 and placing the locking member 341 at least partially within the fixed mating groove 330, thereby connecting the fixing member 34 to the second turbine 33; when the internal liquid temperature is below 0 degrees Celsius, the thermal expansion layer 342 expands, driving the locking member 341 and moving the locking member 341 out of the fixed mating groove 330, thereby disconnecting the fixing member 34 from the second turbine 33. This solution enables the separation member 21 to move towards the second space 102 with less force when the internal liquid is an ice-water mixture and the connection between the first turbine 32 and the second turbine 33 is frozen, and also reduces the damage to the first turbine 32 and the second turbine 33 caused by the separation member 21 when the connection between the first turbine 32 and the second turbine 33 is frozen.

[0101] In some embodiments, please refer to Figures 1 to 4The control unit 50 is used to generate first control information when the pressure is higher than the maximum pressure of the preset pressure range and the liquid flow rate is 0. The first control information is used to instruct the adjustment mechanism 20 to adjust the partition 21 to move toward the second space 102 to expand the first space 101.

[0102] The control unit 50 is used to generate second control information when the pressure information is higher than the preset pressure range and the liquid flow rate information is not zero; the second control information is used to instruct the adjustment mechanism 20 to adjust the partition 21 to move away from the second space 102 to reduce the size of the first space 101.

[0103] The control unit 50 generates third control information when the pressure information is within or below the preset pressure range, or when the liquid flow rate is 0 or not zero. The third control information is used to instruct the adjustment mechanism 20 to fix the partition 21 in place so as to keep the size of the first space 101 unchanged.

[0104] It is understandable that when the water meter housing 10 is made of plastic, the preset pressure range is 600kPa-1000kPa; when the water meter housing 10 is made of metal, the preset pressure range is 1600kPa-2500kPa.

[0105] With this configuration, the control unit 50 receives pressure and flow rate information detected by the pressure sensor 41 and the flow rate sensor 42 and generates control information. The control unit 50 also adjusts the regulating mechanism 20 based on the control information, so that the regulating mechanism 20 can move the partition 21 to expand or shrink the first space 101. This scheme can adjust the explosion-proof water meter according to the pressure and flow rate information of the liquid inside the first space 101.

[0106] In some embodiments, please refer to Figure 5 The water meter housing 10 also includes a water inlet 11, and the explosion-proof water meter also includes a filter device 60, which is located at the water inlet 11 and will filter the liquid passing through the water inlet 11.

[0107] It can be understood that the filtration device 60 is a device used to filter the liquid entering the first space 101.

[0108] With this configuration, by installing a filter device 60 at the water inlet, the explosion-proof water meter can remove impurities from the liquid entering it, thus preventing blockage.

[0109] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
