Split type waterproof controller housing of prepaid water meter

Abstract

The invention relates to the field of water meter devices, in particular to a split type waterproof controller housing of a prepaid water meter. The housing comprises a lower shell, two installation grooves are formed in the lower shell by the enclosing of separation plates, wherein a supporting column is arranged at the bottom of one of the installation grooves, a circuit board is fixed on the supporting column through a bolt, the other installation groove is used for installing batteries and guiding lines, a communication hole is formed in the position between the installation grooves, uppershells are fixed on upper portions of the installation grooves respectively, double clamping plates are arranged on the inner side circumferences of the upper shells, and the double clamping plates are matched with the separation plates. According to the housing, a structure of the water meter is compact and the water meter is convenient to assemble, and a circuit part and a guiding line connection part are divided into two areas which do not interfere with each other, so that the situation of short circuit does not occur; moreover, sealing is conducted between two independent portions and the upper shells, and by adopting the double clamping plates, separation plates can be tightly clamped, and waterproof levels can be greatly improved.

Description

technical field [0001] The invention relates to the field of water meter devices, in particular to a split type prepaid water meter waterproof controller housing. Background technique [0002] With the continuous promotion of smart card technology, contactless smart cards have been widely used in small payment applications such as public transportation, taxis, and oil due to their convenience and safety. In the intelligent water fee charging application where the water meter and the smart card reader are integrated, the user deposits a certain amount of money in the smart card in advance, and the user only needs to use the smart card when paying. According to the data of water resource use, the corresponding amount is deducted from the money stored in the smart card, and the payment process of the water fee is completed.

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing technology, due to the different installation positions of the water meter, it is often necessary to equip a controller. For example, the water meter is installed in the underground or other extreme positions. In order to facilitate the inspection of the water meter, the controller needs to be connected to the water meter through wires. The controller is connected to a place where it is convenient to operate outdoors. The existing controller has poor waterproof performance due to its structure, which is not conducive to long-term installation outdoors.
