Description

Technical Field

[0001] This utility model relates to an intelligent valve-controlled water meter, and more particularly to a wet valve-controlled water meter. Background Technology

[0002] Valve-controlled water meters are a type of smart water meter. They have built-in control valves that allow water flow to be opened and closed via remote commands. Traditional valve-controlled water meters have individually packaged components, and the sealed cavity requires inlets and outlets for power or communication cables between these components. The presence of these inlets and outlets significantly affects the seal, potentially causing electronic component malfunctions. Furthermore, traditional sealed cavities are made of plastic, which has a certain degree of permeability. Over time, moisture can penetrate the gaps between plastic molecules and intrude into the sealed cavity. Additionally, plastic has poor rigidity, making it prone to deformation when the sealing ring is compressed, leading to uneven compression and ultimately, seal failure. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The purpose of this utility model is to provide a wet-type valve-controlled water meter with long-lasting waterproof performance. To achieve the above objective, this utility model adopts the following technical solution:

[0005] (II) Technical Solution

The gearbox is located at the bottom of the electrical module and is penetrated by the valve stem.

[0007] The mechanism module is equipped with a sensing pointer, and the signal conversion box is equipped with a first magnetic transmission bracket and a second magnetic transmission bracket. The first magnetic transmission bracket drives the second magnetic transmission bracket to rotate through several transmission gears. The first magnetic transmission bracket is located on the top of the mechanism module and corresponds to the sensing pointer.

[0008] The electrical module includes a copper cover, inside which are electrically connected circuit boards, batteries and motors. A magnetic sensor is provided on the circuit board.

[0019] (III) Beneficial Effects

[0020] This utility model has significant advantages and beneficial effects compared with the prior art, specifically:

[0021] 1. The electrical module is located on one side of the core module, rather than on the top, which reduces the overall height of the water meter and expands the installation range. At the same time, the electrical module does not obstruct the core module, which facilitates the optimization of the internal structure of the electrical module, such as increasing battery capacity and improving the heat dissipation of the circuit board.

[0022] 2. The signal conversion box and electrical module are designed separately for easy maintenance later.

[0023] 3. Electronic components such as circuit boards, batteries, and motors are housed within a copper enclosure. This sealed cavity, composed of a copper enclosure that blocks water molecules, glass, and a water-impermeable EPDM sealing ring, provides long-term protection for the electronic and electrical components, ensuring the product operates normally within its specified lifespan. Compared to previous independent component packaging structures, the sealed cavity eliminates the need for power supply or communication cable entry / exit points between components.

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] Please see Figures 1 to 6As shown, a wet valve-controlled water meter includes a base meter 1, a signal conversion box 3, an electrical module 4, a gearbox 5, and a valve stem 6, wherein:

[0047] The base meter 1 is provided with a mechanism module 2 at the top, the two ends of the signal conversion box 3 are respectively located at the top of the mechanism module 2 and the electrical module 4, and the reduction gearbox 5 is located at the bottom of the electrical module 4 and is penetrated by the valve stem 6;

[0048] The mechanism module 2 is equipped with a sensor pointer 201, and the signal conversion box 3 is equipped with a first magnetic transmission bracket 301 and a second magnetic transmission bracket 302. The first magnetic transmission bracket 301 drives the second magnetic transmission bracket 302 to rotate through several transmission gears. The first magnetic transmission bracket 301 is located on the top of the mechanism module 2 and corresponds to the sensor pointer 201.

[0049] The electrical module 4 includes a copper cover 401, inside which are a circuit board 402, a battery 403 and a motor 405 that are electrically connected to each other. A magnetic sensor 404 is provided on the circuit board 402. The second magnetic transmission support 302 is located at the top of the electrical module 4 and corresponds to the magnetic sensor 404. The output shaft of the motor 405 is located at the bottom and is fixed with a third magnetic transmission support 406.

[0050] The gearbox 5 is equipped with a fourth magnetic transmission support 501 corresponding to the third magnetic transmission support 406. The fourth magnetic transmission support 501 drives the valve stem 6 to rotate through a number of reduction gears 502.

[0051] Each of the first magnetic transmission support 301, the second magnetic transmission support 302, the third magnetic transmission support 406 and the fourth magnetic transmission support 501 is provided with at least one magnet 7.

[0052] The operating principle of the above technical solution is as follows:

[0053] The movement module 2 of the base meter 1 drives the sensing pointer 201 to rotate. The sensing pointer 201 drives the first magnetic transmission support 301 to rotate through magnetic force. The first magnetic transmission support 301 drives the second magnetic transmission support 302 to rotate through several transmission gears. The circuit board 402 is equipped with a magnetic sensor 404 to sense the number of rotations of the second magnetic transmission support 302, thereby converting the physical reading of the base meter 1 into an electronic reading.

[0054] When the reading exceeds the set value, the circuit board 402 starts the motor 405, the motor 405 drives the third magnetic transmission support 406 to rotate, the third magnetic transmission support 406 drives the fourth magnetic transmission support 501 to rotate through magnetic force, and the fourth magnetic transmission support 501 drives the valve stem 6 to rotate through several reduction gears 502, thereby closing the valve.

[0055] When a user recharges, circuit board 402 starts motor 405, which drives the third magnetic transmission support 406 to rotate. The third magnetic transmission support 406 drives the fourth magnetic transmission support 501 to rotate through magnetic force. The fourth magnetic transmission support 501 drives the valve stem 6 to rotate through several reduction gears 502, thereby opening the valve.

[0056] Preferably, the circuit board 402 is equipped with a remote transmission module, thereby realizing remote control of the water meter.

[0057] Through the above technical solutions, the electrical module 4 is located on one side of the core module 2, rather than on top, thereby reducing the overall height of the water meter and expanding its installation range. Simultaneously, the electrical module 4 does not obstruct the core module 2, facilitating optimization of its internal structure, such as increasing battery capacity or improving circuit board heat dissipation. Furthermore, the separate design of the signal conversion box 3 and the electrical module 4 facilitates future maintenance.

[0058] It is worth mentioning that, to ensure the waterproof performance of the electrical module 4, a tempered glass 408 is embedded in the top of the copper cover 401, and a sealing ring 409 is provided between the tempered glass 408 and the copper cover 401, preferably made of EPDM material. By utilizing the copper cover 401, tempered glass 408, and sealing ring 409, which have low water permeability, moisture is effectively prevented from seeping into the electrical module 4 after long-term use.

[0059] It is understood that the gearbox 5 extends outward to form a fixed bracket 504. The bottom of the fixed bracket 504 is connected to the base meter 1 by screws, and the top is connected to the outer cover 8 by screws. The outer cover 8 encloses the core module 2, signal conversion box 3, electrical module 4 and gearbox 5, and each screw has an anti-disassembly plug on its outer end, thereby improving the physical protection performance of the water meter.

[0060] It should be noted that, in order to ensure the sturdiness of each component, the signal conversion box 3 is fixed inside the outer cover 8, and the outer side of the copper cover 401 is wrapped by a pressure ring 407, which is fixed inside the outer cover 8.

[0061] It should be added that among the reduction gears 502 is a sector gear 503, which is fixed to the top of the valve stem 6, thereby limiting the rotation angle of the valve stem 6.

[0062] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
