Description

Technical Field

[0001] This utility model belongs to the technical field of water meter housings, and in particular relates to a sealing structure for a water meter housing. Background Technology

[0002] Water meters are instruments used to measure water flow, mostly measuring the cumulative flow of water. They are generally divided into two categories: volumetric water meters and velocity water meters. Traditional water meters rely on manual reading, which is affected by factors such as location, working hours, and staff availability, resulting in delayed and inefficient acquisition of water flow information. This has a significant impact on today's efficient production and daily life. Therefore, in recent years, water meter data has been acquired through material networks, which not only improves the timeliness and efficiency of data collection but also provides convenience for users and businesses and reduces labor costs. Existing IoT water meters can be equipped with communication modules, metering modules, circuit boards, and other electronic components, enabling them to perform remote meter reading.

[0003] Currently, the circuit boards and other components installed on existing water meters, under long-term operation, have gaps inside the water meter casing that allow moisture to come into contact with the internal electronic components. This can easily cause the power consumption of the electronic components inside the water meter casing to be damaged due to the humid environment, reducing the reliability of the product.

[0004] In response to the aforementioned problem that the inside of the water meter casing is prone to moisture damage leading to electronic components, this utility model designs a sealing structure for the water meter casing. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing structure for a water meter housing. Through the design structure of the housing, the space where the circuit board is located is sealed and enclosed, providing a dual protection effect. This solves the problem mentioned above where the inside of the water meter housing is easily affected by moisture, leading to damage to electronic components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sealing structure for a water meter housing, comprising a water meter, electronic components, and a mounting housing for sealing and installing the electronic components. The electronic components include a circuit board and a digital display screen. The mounting housing is fixedly mounted on the water meter. The mounting housing includes a bottom mounting shell, a positioning mounting plate, and a top cover. An internal mounting groove is formed inside the bottom mounting shell. A circuit board is fixedly mounted at the bottom of the internal mounting groove. The internal mounting groove is filled with waterproof sealant for the circuit board, which encapsulates the circuit board, providing a high degree of waterproof sealing. A positioning mounting plate is fixedly mounted above the circuit board on the inner wall of the bottom mounting shell. A digital display screen is fixedly mounted on the upper surface of the positioning mounting plate. A top cover is fixedly mounted on the top of the bottom mounting shell. The bottom mounting shell and the positioning mounting plate form a relatively sealed space for the circuit board, providing a certain degree of sealing. Combined with the sealing effect of the waterproof sealant, this provides a double layer of protection.

[0008] As a preferred embodiment of this utility model, the mounting base is provided with a water meter sleeve on one side of the water meter; the inner wall of the water meter sleeve is fixedly installed with the peripheral side of the water meter; and the mounting housing is fixedly installed on the water meter.

[0009] As a preferred technical solution of this utility model, a rotating groove is provided on the peripheral side of the mounting base on one side of the water meter holder; the water meter cover is rotatably fitted on the inner wall of the rotating groove; the water meter cover is designed to be rotating, so that it can be rotated open when viewing; and can be rotated back on when not viewing.

[0010] As a preferred embodiment of this utility model, a non-magnetic sensor is fixedly installed at the bottom of the mounting base.

[0011] As a preferred technical solution of this utility model, a sealing ring is fixed between the top of the mounting base and the top cover; the top cover and the sealing ring seal the top of the mounting base, so that the inner wall of the mounting base is in a sealed space, thereby greatly preventing moisture from entering the mounting housing and contacting the internal electronic components, achieving a full protection effect for the electronic components, and also ensuring the service life and reliability of the product.

[0012] As a preferred embodiment of this utility model, limiting plates are provided on both sides of the positioning mounting plate; the limiting plates limit and fix the electronic devices installed in the mounting housing.

[0013] As a preferred technical solution of this utility model, the gap between the inner wall of the mounting base and the edge of the positioning mounting plate is filled with gap sealant; a locking post is fixed to the bottom wall of the built-in mounting groove, and a locking hole is opened on the circuit board, with the locking post cooperating with the locking hole.

[0014] As a preferred embodiment of this invention, a glass slide for observation is sealed and fixed on the upper cover.

[0015] This utility model has the following beneficial effects:

[0016] This invention achieves multiple waterproof protections for electronic devices such as circuit boards by creating a double and multiple sealing and airtight structure inside the housing; it has the advantages of double and multiple protections, improved product lifespan and reliability.
