Description

Technical Field

[0001] The utility model relates to a communication device, in particular to an intelligent water meter monitor. Background Art

[0002] The water meter monitor is a communication device set between the water meter and the remote platform. The water meter data is transmitted to the water meter monitor via wired means, and the water meter monitor then transmits the data to the remote platform wirelessly. The use environment of the water meter monitor is usually relatively harsh, so it has high requirements for waterproofing and moisture resistance. Certain measures need to be taken to improve the waterproof performance, such as using potting glue (polyurethane glue) to encapsulate the mainboard.

[0003] However, the main board inside the water meter will generate heat when working, and polyurethane glue is a hard glue. When heated, it will produce stress to squeeze the main board. The main board will be easily damaged due to the stress for a long time, which affects its service life. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] like Figure 1 As shown, the water meter intelligent monitor includes a monitor body 1.

[0032] The monitor body comprises a housing 1-1, a main board 3, and a battery 4. An antenna 2 is installed on the side of the housing. The antenna is a rod-shaped antenna.

[0033] The housing has a signal line. The signal line includes a first signal line 2-1 and a plurality of second signal lines 2-2. The first signal line connects the mainboard with the antenna (sending water meter data to the remote platform via the antenna). The second signal line connects the mainboard with the external water meter (sending water meter water volume, pressure, temperature and other data to the water meter intelligent monitor). Figure 2 As shown, there are three second signal lines, each of which has multiple core wires built in, and can be connected to multiple external water meters at the same time.

[0034] The housing includes a first housing 1.1 and a second housing 1.2 which are isolated from each other. The bottom wall of the first housing is provided with a first wire hole 2.1 and a second wire hole 2.2. The side wall between the first housing and the second housing is provided with a third wire hole 2.3 (omitted in the figure). The mainboard is arranged in the first housing. The battery is arranged in the second housing, and the battery is used to supply power to the mainboard.

[0035] The second shell is arranged above and below the first shell, and the second shell is arranged above the first shell. The back of the first shell is open and is provided with a first cover plate 1-4 (fixed with bolts), a sealing ring is provided between the first shell and the first cover plate, and the top surface of the second shell is open and is provided with a second cover plate 1-5 (fixed with bolts), and a sealing ring is provided between the second shell and the second cover plate. Since the second cover plate is arranged on the top of the shell, the battery can be easily replaced.

[0036] The mainboard is encapsulated in the first housing by double-layer encapsulation glue. The battery is encapsulated in the encapsulation bucket 6 by hard encapsulation glue, and the encapsulation bucket is arranged in the second housing.

[0037] The double-layer potting glue includes hard potting glue and soft potting glue. The first shell is provided with a potting groove 1-3 and a baffle 5. The potting groove is formed by the partition 1-2 and the inner wall of the first shell. The baffle 5 is fixed in the first shell and presses the partition to seal the potting groove.

[0038] like Figure 7 As shown, the baffle separates the inner cavity of the first shell into two cavities: an inner cavity 1.3 surrounded by the partition, the baffle and the inner wall of the first shell, and an outer cavity 1.4 surrounded by the first cover plate, the baffle and the inner wall of the first shell.

[0039] The mainboard is encapsulated in the inner cavity by soft potting glue. The mainboard is installed in the potting tank and encapsulated by soft potting glue, and the soft potting glue submerges the mainboard. The inner cavity is encapsulated in the outer cavity by soft potting glue, and the hard potting glue submerges the baffle.

[0040] Since the outer cavity is close to the first cover plate, the opening between the first shell and the first cover plate is relatively large, and the sealing protection needs to be strengthened. Hard potting glue is used as the first-level sealing. The inner cavity is far away from the first cover plate, and soft potting glue is used as the second-level sealing. The double-layer potting glue sealing method is adopted, which greatly improves the waterproof performance. At the same time, the stress generated by the soft potting glue is small, and the mainboard is protected by the soft potting glue, which is not easy to be damaged, and the service life of the mainboard is extended. The stress generated by the hard potting glue is relatively large, and it is set on the outside and will not contact the mainboard, which also improves the waterproof performance.

[0041] Since the first wire hole, the second wire hole and the third wire hole are relatively small in size, the waterproof performance can be ensured by only using soft potting glue for protection. The first wire hole, the second wire hole and the third wire hole are all submerged in the soft potting glue for sealing.

[0042] The soft potting glue is made of silicone gel, and the hard potting glue is made of polyurethane glue.

[0043] The first shell of the housing is provided with a display screen 7 and a transparent cover 8. The display screen is electrically connected to the main board and is used to display the operation data of the water meter. The transparent cover serves as an infrared window for the external handheld device to communicate with the main board.

[0044] The mainboard is electrically connected to the antenna via a first signal line passing through the first wire hole. The mainboard is electrically connected to the external water meter via a second signal line passing through the second wire hole. The battery is electrically connected to the mainboard via a wire passing through the third wire hole.

[0045] One end of the first signal line extends into the first housing through the first line hole and is electrically connected to the mainboard, and the other end of the first signal line is electrically connected to the antenna. One end of the second signal line extends into the first housing through the second line hole and is electrically connected to the first mainboard, and the other end of the second signal line is electrically connected to the external water meter. The battery is electrically connected to the mainboard via a wire passing through the third line hole.

[0046] All components of the utility model are prior art and can be purchased from outside.

[0047] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
