Description

Technical Field

[0001] The utility model relates to the field of water meters, in particular to a wireless communication device. Background Art

[0002] The water meter communication device is used to transmit data between the water meter and the remote platform. The water meter data is transmitted to the water meter communication device wirelessly, and the water meter communication device then transmits the data to the remote platform wirelessly.

[0003] Since the installation environment of the water meter communication device is relatively harsh, high requirements are placed on the waterproof and moisture-proof performance. At the same time, the water meter communication device relies on its own power supply, and manual maintenance is required after the power supply is exhausted.

[0004] However, the waterproof and moisture-proof performance of existing water meter communication devices is still difficult to meet the requirements, which makes the internal electronic components extremely easy to be damaged, affecting the service life. In addition, due to the structure and size limitations of the water meter communication device, a larger capacity power supply cannot be installed, which increases the labor maintenance cost.

[0008] The second shell is provided with two battery cavities which are independently arranged on the left and right sides, and each battery cavity is provided with a battery.

[0009] The first shell is provided with a first wire hole communicating with the outside and a second wire hole communicating with each battery cavity.

[0010] The circuit board is electrically connected to the antenna via a first wire passing through a first wire hole; and the circuit board is electrically connected to two batteries simultaneously via a second wire passing through a second wire hole.

[0011] The second wire hole is provided with a rubber plug.

[0012] The first shell is equipped with a front cover; each battery cavity of the second shell is equipped with a bottom cover.

[0025] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] As Figure 1 shown, a wireless communication device includes a monitor body and an antenna 2.

[0027] The monitor body comprises a housing 1, a circuit board 3 and a battery 4. The antenna is mounted on the top of the housing, the circuit board is used for collecting, processing and transmitting water meter data, the battery is used for supplying power to the circuit board, and the circuit board is electrically connected to the antenna and the battery.

[0028] The housing comprises a first housing 1.1 and a second housing 1.2. Figure 4 As shown, the first shell and the second shell are arranged front and back and isolated from each other. The first shell and the second shell divide the outer shell into two layers, front and back. The first shell is close to the front of the outer shell ( Figure 4 The right side of the housing is used to install the circuit board, and the second housing is close to the rear of the housing ( Figure 4 for installing the battery.

[0029] The front surface of the first shell is open and is provided with a front cover 6 , a sealing ring 8 is provided between the first shell and the front cover, and the bottom surface of the second shell is open and is provided with a bottom cover 7 .

[0030] The circuit board is fixed in the first shell, and the first shell is filled with potting glue (omitted in the figure) to encapsulate the circuit board. The potting glue is polyurethane potting glue. The circuit board is equipped with a communication module, and the communication module includes an NB-IOT communication module and a Bluetooth module.

[0031] The second housing is provided with two battery chambers 1.3, which are arranged left and right ( Figure 5 The left and right sides) and are isolated from each other, each battery cavity extends vertically ( Figure 5 A battery is installed in the vertical direction, and each battery cavity is equipped with a bottom cover. The battery model is ER34615, and the voltage is 3.6V.

[0032] The first shell is provided with a first wire hole 1.1.1 and a second wire hole 1.1.2, the first wire hole connects the inner cavity of the first shell and the outside of the shell, the two second wire holes respectively connect the first shell and the battery cavity, the NB-IOT communication module of the circuit board is electrically connected to the antenna through the first wire passing through the first wire hole, and the circuit board is electrically connected to the two batteries at the same time through the second wire passing through the second wire hole.
