Description

Technical Field

[0001] The present invention relates to the technical field of smart water meters, and in particular to a smart water meter based on the Internet of Things that facilitates water consumption control. Background Art

[0002] Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption, transmit water consumption data, and settle transactions. Combined with the Internet of Things technology, users can control the solenoid valve in the smart water meter through the Internet of Things to realize the opening and closing of the smart water meter and water consumption control. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, it is a great improvement and more convenient for users to save water. Therefore, when renovating old urban areas, old water meters will be replaced with this new type of smart water meter.

[0003] When installing the existing smart water meters based on the Internet of Things to control water consumption, the installation of the water meters is usually completed through flange connections between flange plates. When constructing new water supply pipelines, the size of the flanges can be unified to ensure that the flanges match each other during installation. However, when upgrading water meters in old urban areas, the installation holes on the flanges of the old water pipes are inconsistent in position and size, and the position and size of the installation holes on the flanges of the existing smart water meters are fixed and cannot be adaptively adjusted, so the applicability is very poor. When installing the smart water meters, it is necessary to prepare smart water meters with flanges of various specifications and sizes in advance. Moreover, when docking and installing the flanges, it is usually necessary for the staff to install multiple bolts one by one in sequence, which is very cumbersome to operate and seriously affects the installation efficiency of the smart water meters. Moreover, because they need to be installed one by one, the tightness of the bolts is inconsistent, and the flanges cannot be ensured to be parallel, so the sealing of the flanges is poor. Summary of the invention

[0004] The object of the present invention is to solve the drawbacks existing in the prior art, such as: when the existing intelligent water meter based on the Internet of Things and convenient for controlling water consumption is installed, it is usually completed by flange connection between flange plates. When building a new water supply pipeline, the sizes of the flanges can be unified to ensure that the flanges match each other during installation. However, when upgrading the water meters in old urban areas, due to the inconsistent positions and sizes of the mounting holes on the flanges of the old water pipes, and the positions and sizes of the mounting holes on the flanges of the existing intelligent water meters are fixed and cannot be adjusted adaptively, the applicability is very poor. When installing an intelligent water meter, it is necessary to prepare in advance intelligent water meters with various different specifications and sizes of flanges as spares. Moreover, when docking and installing between flanges, it is usually necessary for the staff to install multiple bolts one by one in sequence, which is very cumbersome to operate, seriously affecting the installation efficiency of the intelligent water meter. And because the bolts need to be installed one by one, the tightening degree of each bolt installation is inconsistent, and the flanges cannot be ensured to be parallel, so the sealing performance between the flanges is poor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An intelligent water meter based on the Internet of Things and convenient for controlling water consumption, including an intelligent water meter housing, two water connection pipes are symmetrically arranged on the outer side wall of the intelligent water meter housing, flange plates are arranged on both of the two water connection pipes, a plurality of moving adjustment seats are arranged between the water connection pipes and the flange plates, a plurality of the moving adjustment seats are all connected with fastening seats through limiting devices, a gear is fixedly connected to the outer side wall of the fastening seat, a threaded groove is arranged in the fastening seat, the gear is meshed and connected with the inner side wall of the moving adjustment seat, a portable rotation device is arranged on the flange plate, and a protection device is arranged between the water connection pipe and the flange plate.

[0013] 2. Since the limiting member on the limiting device is composed of two engaging members spliced together, the fastening seat can be disassembled from above. Therefore, when the size of the threaded groove on the fastening seat is inconsistent with the size of the mounting hole, only need to rotate the first limit nut and disassemble it from the fixed rod, then the two engaging members can be separated, and the fastening seat can be taken out. Then, replace it with a new fastening seat with a suitable threaded groove size. The disassembly and installation operations are simple and convenient to use. Since the new fastening seat with a corresponding threaded groove size can be replaced according to the size of the mounting hole on the corresponding flange at the installation site, the applicability of the present invention is further improved.

[0014] 3. Only need to hold the handle, insert the insertion rod into the positioning groove on the flange, and then rotate the handle around the axis of the water connection pipe to drive the fastening seat to rotate around the bolt, thereby completing the threaded connection and installation between the bolt and the threaded groove on the fastening seat, and simultaneously completing the installation of multiple bolts at one time while rotating the flange. The operation is simple and convenient to use. Since the installation progress of each bolt is the same, the sealing performance between the flanges is well guaranteed, and the installation efficiency is significantly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Refer to Figures 1-6, An intelligent water meter based on the Internet of Things that facilitates the control of water consumption, including an intelligent water meter housing 1. On the outer side wall of the intelligent water meter housing 1, two water connection pipes 2 are symmetrically arranged. Flange plates 3 are provided on both of the two water connection pipes 2. A plurality of movable adjustment seats 4 are arranged between the water connection pipe 2 and the flange plate 3. A limit ring 5 is fixedly connected to the water connection pipe 2. A limit internal gear ring 6 is fixedly connected to the inner side wall of the flange plate 3. A tooth groove 7 is provided on the outer side wall of the movable adjustment seat 4. Both the limit ring 5 and the limit internal gear ring 6 are located in the tooth groove 7. A plurality of movable adjustment seats 4 are all connected with a fastening seat 8 through a limiting device.

[0020] The limiting device includes a limit card 11. Two limit holes are provided on the limit card 11. The two ends of the fastening seat 8 are respectively rotatably connected in the two limit holes. The limit card 11 is slidably connected to the outer side wall of the movable adjustment seat 4. The limit card 11 is composed of two engaging members 12 spliced together. Fixed rods 13 are fixedly connected to the side walls of both of the two engaging members 12. The fixed rods 13 are arranged in a semi-cylindrical shape. Matching threads are provided on the curved side walls of the two fixed rods 13. A first limit nut 14 is threadedly connected to the outer side walls of the two fixed rods 13. A gear 9 is fixedly connected to the outer side wall of the fastening seat 8. A threaded groove 10 is provided inside the fastening seat 8. The gear 9 is meshed and connected to the inner side wall of the movable adjustment seat 4. A portable rotation device is provided on the flange plate 3.

[0021] The portable rotation device includes a plurality of positioning grooves 15. The plurality of positioning grooves 15 are symmetrically arranged on the outer side wall of the flange plate 3. A plug rod 16 is inserted into the positioning groove 15. A grip 17 is fixedly connected to the end of the plug rod 16 away from the flange plate 3. The edge of the end of the plug rod 16 close to the flange plate 3 is rounded. An anti-slip rubber film is provided on the outer side wall of the grip 17. A protective device is arranged between the water connection pipe 2 and the flange plate 3. The protective device includes a retaining ring 18. The retaining ring 18 is fixedly connected to the outer side wall of the water connection pipe 2. A plurality of threaded rods 19 are symmetrically and fixedly connected to the side wall of the flange plate 3 close to the intelligent water meter housing 1. Two protective plates 20 are arranged between the water connection pipe 2 and the threaded rods 19. A second limit nut 21 is threadedly connected to the outer side wall of the threaded rod 19.

[0022] When the present invention is in use, since the movable adjustment seat 4 is rotatably connected between the water connection pipe 2 and the flange plate 3, and because both the limit ring 5 and the limit gear ring 6 are located in the tooth groove 7, the limit ring 5 and the limit gear ring 6 both have a limiting effect on the movable adjustment seat 4, so that the movable adjustment seat 4 can only move between the outer side wall of the water connection pipe 2 and the inner side wall of the flange plate 3. And the fastening seat 8 is connected to the limit ring 5 through the limiting device, and the limit card 11 is rotatably connected to the inner side wall of the limit ring 5. Therefore, the fastening seat 8 can also move around the inner side wall of the limit ring 5. Under the combined action of the two, the position of the fastening seat 8 can be arbitrarily adjusted between the outer side wall of the water connection pipe 2 and the inner side wall of the flange plate 3. Therefore, the position of the threaded groove 10 can be arbitrarily adjusted; In the design of the present invention, the fastening seat 8 and the threaded groove 10 correspond to the mounting holes on the traditional flange structure. On this basis, the nut structure is integrated with the mounting holes. Since the position of the fastening seat 8 can be moved and adjusted, the flange structure in the present invention can be adaptively adjusted according to the positions of the mounting holes on the corresponding flange at the installation site, thus significantly improving the installation adaptability of the intelligent water meter proposed by the present invention, making the intelligent water meter based on the Internet of Things and convenient for controlling water consumption proposed by the present invention applicable to the butt joint installation between different specifications and sizes of flanges on the water pipe at the installation site; Since the limiting member 11 on the limiting device is composed of two engaging members 12 spliced together, the fastening seat 8 can be disassembled from above. Therefore, when the size of the threaded groove 10 on the fastening seat 8 is inconsistent with the size of the mounting hole, only need to rotate the first limiting nut 14 and disassemble it from the fixed rod 13, then the two engaging members 12 can be separated, and the fastening seat 8 can be taken out. Then replace it with a new fastening seat 8 with a suitable size of the threaded groove 10. The disassembly and installation operations are simple and convenient to use. Since the new fastening seat 8 with a corresponding size of the threaded groove 10 can be replaced according to the size of the mounting hole on the corresponding flange at the installation site, the applicability of the present invention is further improved; After adjusting the positions of the fastening seats 8 and moving them to align with the positions of the mounting holes on the flange of the water pipe at the installation site, insert one end of the bolt through the mounting hole on the flange of the water pipe at the installation site and into the threaded groove 10 of the fastening seat 8. Install multiple bolts in sequence. Then, hold the handle 17 and insert the insertion rod 16 into the positioning groove 15 on the flange plate 3, and then rotate the handle 17 around the axis of the water pipe 2. Drive the flange plate 3 to rotate by using the handle 17. Since the position of the fastening seat 8 is fixed by the bolt at this time, as the flange plate 3 rotates, under the meshing connection of the limiting gear ring 6 and the tooth groove 7, and the limiting action on the fastening seat 8, the moving adjustment seat 4 drives the gear 9 on the fastening seat 8 to rotate around the center of gravity of the threaded groove 10, and then drives the fastening seat 8 to rotate around the bolt, thus completing the threaded connection and installation between the bolt and the threaded groove 10 on the fastening seat 8, and completing the simultaneous installation of multiple bolts at the same time while rotating the flange plate 3. The operation is simple and convenient to use. Since the installation progress of each bolt is the same, the sealing performance between the flanges is well guaranteed, and the installation efficiency is significantly improved; After completing the docking installation between the flange 3 and the flange on the water pipe at the installation location, place the two protective plates 20 in sequence between the outer sidewall of the water connection pipe 2 and the threaded rod 19. The protective plate 20 is arranged closely against the sidewall of the retaining ring 18 close to the flange 3. The retaining ring 18 is used in cooperation with the flange 3 to limit and fix the protective plate 20. Then, install a plurality of second limit nuts 21 onto the threaded rod 19 in sequence to further limit and fix the protective plate 20, enhancing the fixing effect and preventing the protective plate 20 from falling off. The structure between the flange 3 and the water connection pipe 2 is shielded by the protective plate 20 to prevent dust and foreign objects from entering, which may affect the disassembly, installation, and replacement during the repair when the subsequent water meter fails.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
