Description

Technical Field

[0001] This utility model relates to the field of outdoor water meter technology, specifically to an outdoor water meter with an anti-drip flow guiding structure. Background Technology

[0002] An outdoor water meter is a metering device installed outdoors, primarily used to accurately measure the amount of tap water flowing through pipes. It typically consists of the meter body, a protective casing, connecting pipes, and related auxiliary structures. It can adapt to complex outdoor climates and records water consumption through internal mechanical or electronic components, providing data for water supply departments to calculate bills and for users to understand their water usage. Some models also feature anti-drip, anti-freeze, and anti-theft protection functions to ensure long-term stable operation.

[0003] To prevent malicious opening of outdoor water meters, a special anti-theft cover is used. It is connected to the water meter body by a special buckle or thread, and the edge of the cover is designed with a one-time break structure. It can only be unscrewed with a special tool. Once forcibly pried open, it will leave obvious damage marks. This not only makes it easy for supervisors to quickly identify abnormalities, but also forms an effective deterrent through the irreversible nature of the physical structure.

[0004] The one-time breakage structure leads to inconvenient maintenance. Even if it needs to be opened for normal maintenance, a new cover needs to be replaced, which increases the cost of consumables and operation steps. It cannot achieve an efficient anti-theft measure. This method has poor environmental adaptability. When exposed to outdoor wind, rain, ultraviolet rays, low temperature and other environments for a long time, the buckles or threads of the cover are prone to aging and corrosion, which may make it difficult to open during normal maintenance, thus increasing the difficulty of maintenance. In order to address the above problems, an outdoor water meter with an anti-drip flow guiding structure is proposed. Utility Model Content

[0037] Working principle: When end cover 2 is closed, bottom connecting rod 13 enters the corresponding position inside housing 1. Second spring 6 causes limiting shaft 7 to enter rotating shaft 9. By turning hexagonal block 5 with external wrench, the wrench engages hexagonal block 5 and rotates, driving rotating rod 3 and limiting shaft 7 to rotate synchronously. Limiting shaft 7 cooperates with rotating shaft 9. After rotating shaft 9 rotates, it drives bidirectional threaded rod 11 to rotate via bevel gear set 10. Bidirectional threaded rod 11 drives the limiting rods 12 on both sides to move. Finally, limiting rod 12 passes through connecting rod 13, completing the end cover. After locking 2, the hidden sealing block 14 is slid into the end cover 2, allowing the hexagonal block 5 to enter the rotating rod 3. The hidden sealing block 14 further conceals the key structure, preventing unauthorized opening. When it is necessary to open the end cover 2, the hidden sealing block 14 is slid out, causing the hexagonal block 5 to pop out. The wrench is operated in the opposite direction, causing the double-threaded rod 11 to reverse, the limit rod 12 to disengage from the connecting rod 13, and the hexagonal block 5 is pressed to compress the first spring 4. This releases the linkage between the rotating rod 3 and the outside, allowing the end cover 2 and the water meter body 25 to be opened. At the connection point with the water pipe 29, a flow guiding structure is formed by the fixing rod 19, the lower sealing ring 20, the top cover 22, and the upper sealing ring 23. If water leaks at the connection point, the liquid first contacts the upper sealing ring 23 and the top cover 22. Since the top cover 22 is connected to the fixing rod 19 by bolts 24, and the fixing rod 19 has a through groove, the leaking liquid will flow along the inner wall of the sealing ring and the top cover 22, through the through groove, into the water tank 16, preventing water droplets from leaking out and damaging the surrounding structure. When the water meter needs to be heated in winter, the water tank 16 is filled with... When the heating filament 18 is energized, it heats the liquid inside the tank. The water pump 17 starts and transfers the high-temperature liquid to the jacket 26 on the outer ring of the water meter body 25. The jacket 26 wraps around the water meter and heats the water meter through heat transfer to prevent low-temperature freezing damage. This completes the heat exchange of the liquid and continuously ensures the working temperature of the water meter. The liquid level sensor 30 in the water tank 16 monitors the liquid level in real time. If the liquid level is abnormal, it can be fed back and reminded through the front controller 31 of the tank 1, so that water can be added through the water inlet 28 and drained through the drain outlet 27 for maintenance.
