Description
Technical Field
[0001] This utility model relates to the field of water meter equipment technology, and in particular to an electronic water meter with protective components. Background Technology
[0002] With the development of refined water resource metering management, electronic water meters have been widely used in residential water use, industrial production water use and other scenarios due to their advantages such as high metering accuracy and convenient reading.
[0003] However, existing electronic water meters still suffer from numerous technical defects in practical use. Firstly, the internal transmission components (such as gears and impellers) of traditional electronic water meters lack stable support structures. Under prolonged high-speed operation under water flow impact, they are prone to shaft eccentricity and gear wear, leading to increased measurement errors and severely impacting the meter's lifespan and accuracy. Secondly, electronic water meters are often installed in complex environments such as outdoor pipelines and underground wells. Existing products lack sufficient protection, allowing external dust and moisture to easily penetrate the internal counter and gear components, causing corrosion or short circuits. External impacts can also directly damage core components, leading to meter malfunctions. Furthermore, existing electronic water meters are difficult to assemble and maintain, mostly employing an integrated fixed structure. When internal components malfunction, the entire meter must be disassembled, a cumbersome process that can damage other related components, increasing maintenance costs and downtime. Additionally, the installation and fixing methods are limited, making it difficult to adapt to different pipe installation scenarios and lacking flexibility. These problems restrict the reliability and practicality of electronic water meters, necessitating a new electronic water meter structure that combines protective performance, measurement accuracy, and ease of installation and maintenance. Utility Model Content
[0004] The purpose of this utility model is to provide an electronic water meter with protective components, which can improve metering accuracy and structural stability, enhance external protection performance, simplify installation and maintenance processes, and adapt to various application scenarios.
[0005] To achieve the above objectives, an electronic water meter with protective components is provided, including a base sleeve, a first bearing, and an outer ring. An impeller is rotatably connected to the inner ring of the first bearing, and a multi-gear assembly is fixedly connected to the connecting shaft of the impeller. The outer surface of the outer ring is provided with an external thread, and the inner ring of the bottom sleeve is provided with an internal thread. The internal thread of the bottom sleeve is threadedly connected to the external thread of the outer ring.
[0006] According to the electronic water meter with protective components, the multi-gear assembly includes a rotating shaft, on the outer surface of which gears are fixedly connected, and at one end of which a second bearing is rotatably connected.
[0007] According to the electronic water meter with protective components, a first circular groove is provided at the right end of the outer ring, and the outer surface of the second bearing is fixedly connected to the bottom of the first circular groove.
[0008] According to the electronic water meter with protective components, a second circular groove is provided at the left end of the outer ring, and a counter is provided at the bottom of the second circular groove.
[0009] According to the electronic water meter with protective components, the surface of the second circular groove is provided with a glass sheet.
[0010] According to the electronic water meter with protective components, the surface of the base sleeve is provided with multiple round holes.
[0011] According to the electronic water meter with protective components, a protective sleeve is provided around the outer ring, and multiple protrusions are provided on the outer surface of the protective sleeve.
[0012] According to the electronic water meter with protective components, the protective sleeve has caps at both ends, and bolts penetrate the top and bottom of the caps respectively. The bolts pass through the caps and the protective sleeve, and nuts are threaded onto the outer surface of the bolts.
[0013] This utility model has the following beneficial effects: 1. Compared with the prior art, this utility model forms a closed protective structure by using the outer protective sleeve and the end caps to form a closed protective structure. With the buffering effect of the protrusions, it effectively resists the damage to the internal impeller, gear assembly and counter caused by external collisions and impacts. At the same time, it blocks the intrusion of foreign objects such as water vapor and dust, which significantly improves the anti-interference ability and service life of the equipment in complex environments. Moreover, the glass plate not only ensures the sealing and protection effect of the counter, but also does not affect the intuitiveness of data reading.
[0014] 2. Compared with the prior art, this utility model adopts a threaded connection between the bottom sleeve and the outer ring to realize the detachable assembly of the core components. When the internal components fail, they can be quickly disassembled and repaired without replacing the whole, thus reducing maintenance costs. The multiple round holes on the surface of the bottom sleeve are adapted to the fixing requirements of different installation scenarios, and the protrusions on the outer surface of the protective sleeve enhance the grip friction, improving the convenience of installation and adjustment and the assembly accuracy.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] Reference Figure 1-5This utility model discloses an electronic water meter with protective components, comprising a base sleeve 1, a first bearing 3, and an outer ring 6. An impeller 4 is rotatably connected to the inner ring of the first bearing 3. A multi-gear assembly 5 is fixedly connected to the connecting shaft of the impeller 4. The multi-gear assembly 5 includes a rotating shaft 501, a gear 502 is fixedly connected to the outer surface of the rotating shaft 501, and a second bearing 503 is rotatably connected to one end of the rotating shaft 501. A first circular groove 7 is provided at the right end of the outer ring 6, and the outer surface of the second bearing 503 is fixedly connected to the bottom of the first circular groove 7. A second circular groove 8 is provided at the left end of the outer ring 6, and a counter 9 is provided at the bottom of the second circular groove 8. A glass sheet 10 is provided on the surface of the second circular groove 8. The base sleeve 1 serves as the basic load-bearing component of the device and is detachably connected to the outer ring 6 via an internal thread 12 and an external thread 11, which ensures the stability of the overall structure and facilitates disassembly and maintenance in the future. The inner ring of the first bearing 3 is rotatably connected to the impeller 4, providing stable support for the high-speed rotation of the impeller 4 and reducing frictional losses during rotation. The connecting shaft of the impeller 4 is fixedly connected to the multi-gear assembly 5. When the impeller 4 rotates under the influence of fluid or external force, it can drive the multi-gear assembly 5 to rotate synchronously through the connecting shaft. In the multi-gear assembly 5, the gear 502 fixed on the outer surface of the rotating shaft 501 can transmit the rotational speed to the counter 9 through meshing transmission. The second bearing 503 at one end of the rotating shaft 501 is fixed to the bottom of the first circular groove 7 at the right end of the outer ring 6, further improving the coaxiality and stability of the rotation of the rotating shaft 501 and avoiding gear eccentricity or wear caused by long-term operation. The second circular groove 8 at the left end of the outer ring 6 provides installation space for the counter 9. The counter 9 can accurately record the rotational speed of the impeller 4 through the transmission of the gear 502. The glass plate 10 on the surface of the second circular groove 8 plays a sealing and protective role, which can prevent dust and moisture from entering and affecting the accuracy of the counter 9, and also facilitates intuitive reading of the counting data.
[0019] In the above structure, both the first bearing 3 and the second bearing 503 are deep groove ball bearings, which have good radial load capacity and low friction characteristics, and are suitable for the high-speed rotation conditions inside the water meter; the gear 502 is injection molded from engineering plastic material, which not only reduces the overall weight of the transmission mechanism, but also has good wear resistance and corrosion resistance, further improving the long-term operational stability of the equipment.
[0020] The outer ring 6 has an external thread 11 on its outer surface, and the inner ring of the bottom sleeve 1 has an internal thread 12. The internal thread 12 of the bottom sleeve 1 is threaded to the external thread 11 of the outer ring 6. The surface of the bottom sleeve 1 has multiple round holes 2. The outer ring 6 is surrounded by a protective sleeve 13. The outer surface of the protective sleeve 13 has multiple protrusions 14. Both ends of the protective sleeve 13 are provided with caps 15. Bolts 16 pass through the top and bottom of the caps 15, respectively. The bolts 16 pass through the caps 15 and the protective sleeve 13. Nuts 17 are threaded onto the outer surface of the bolts 16. The protective sleeve 13 surrounding the outer ring 6 provides external protection for the entire device. The multiple protrusions 14 on its outer surface can enhance the grip friction, making it convenient to install or adjust the position of the device. At the same time, it can buffer the impact force during collisions and reduce damage to internal components. The caps 15 at both ends of the protective sleeve 13 are fixed by through bolts 16 and nuts 17. The bolts 16 pass through the caps 15 and the protective sleeve 13 in sequence and are threaded to the nuts 17 to form a closed protective space, which effectively prevents foreign objects from entering. The multiple round holes 2 on the surface of the bottom sleeve 1 can be used to fix the entire device to external equipment such as pipes or machine bodies, improving the flexibility and stability of installation and adapting to different application scenarios.
[0021] In the above structure, the length of the protective sleeve 13 is slightly greater than the length of the outer ring 6, ensuring that the outer ring 6 and internal components are completely covered by the protective sleeve 13; the height of the protrusion 14 is 3-5mm, which ensures the friction when gripping without affecting the overall installation space of the device due to excessive height; the bolt 16 is made of stainless steel and is used with the anti-loosening nut 17 to effectively prevent loosening caused by vibration during long-term use and improve the stability of the protective structure.
[0022] Working principle: An electronic water meter with protective components is installed by first assembling the impeller 4 and the first bearing 3 and fixing them inside the base sleeve 1. Then, one end of the rotating shaft 501 of the multi-gear assembly 5 is fixed in the first circular groove 7 of the outer ring 6 through the second bearing 503, so that the gear 502 of the multi-gear assembly 5 meshes with the gear of the connecting shaft of the impeller 4. Then, the counter 9 is fixed in the second circular groove 8 of the outer ring 6, and the input gear of the counter 9 meshes with the end gear of the multi-gear assembly 5. Finally, the glass plate 10 is sealed and fixed on the surface of the second circular groove 8. The outer ring 6 of the assembled internal components is threaded to the inner thread 12 of the base sleeve 1 via the external thread 11, thus completing the assembly of the core components. Next, the protective sleeve 13 is fitted around the outer ring 6, and the sleeve caps 15 are installed at both ends of the protective sleeve 13. The sleeve caps 15 and the protective sleeve 13 are fixed with bolts 16 and nuts 17 to form a complete protective structure. Finally, the entire device is fixed to the preset installation position through the round hole 2 on the surface of the base sleeve 1, and the inlet and outlet of the water meter are connected to the pipeline. When in use, the fluid flows through the inlet and outlet of the water meter, driving the impeller 4 to rotate. The impeller 4 drives the rotating shaft 501 and gear 502 of the multi-gear assembly 5 to rotate through the connecting shaft. The gear 502 transmits the rotation speed to the counter 9 through meshing transmission. The counter 9 converts the fluid flow rate according to the preset transmission ratio and the parameters of the impeller 4 and displays it. The operator reads the flow rate data through the glass plate 10. The enclosed structure formed by the protective cover 13 and the cover 15 effectively blocks the impact of external collisions, dust, moisture and other factors on the internal components. The protrusion 14 enhances the ease of grip and cushioning effect. When maintenance is required, simply remove the bolts 16 and nuts 17 to remove the cover 15 and the protective cover 13, and then rotate the bottom sleeve 1 to separate it from the outer ring 6. The internal components can then be inspected or replaced. The operation is convenient and efficient.
[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
