Description

Technical Field

[0001] This utility model relates to an ultrasonic water meter with an external battery compartment, belonging to the field of water meter technology. Background Technology

[0002] An ultrasonic water meter is a water meter that calculates the water flow rate by analyzing the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water.

[0003] The battery compartment of existing ultrasonic water meters is located inside the control box, below the PCB board compartment. Due to protection considerations, the interior is sealed with glue, making battery replacement a complicated procedure that requires a high level of skill from the operator.

[0004] As the data transmission frequency of ultrasonic water meters increases, the lifespan of the built-in battery will be greatly shortened, requiring battery replacement during the lifespan of the ultrasonic water meter. However, in order to improve the protection level, ultrasonic water meters often use glue potting inside the control box, which makes the battery replacement process cumbersome, time-consuming, and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic water meter with an external battery compartment. By modularly designing the battery into a battery compartment, the main body of the ultrasonic water meter and the battery are separated, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An ultrasonic water meter with an external battery compartment includes a water meter body and a battery compartment, wherein the battery compartment and the water meter body are separately disposed; the battery compartment is externally disposed on the surface of the water meter body; the battery in the water meter body and the battery compartment are connected by a waterproof plug; the battery compartment and the water meter body are also fixedly connected by screws.

[0008] A further improvement to this technical solution is that an insertion hole is provided on the water meter compartment, and a waterproof plug is provided on the battery compartment.

[0009] A further improvement to this technical solution is that the waterproof plug has a conical stepped structure, with a rubber sealing ring installed at each step.

[0010] A further improvement to this technical solution is that the waterproof plug has a three-step conical step structure.

[0011] A further improvement to this technical solution is that a rubber sealing ring is installed at the junction of the battery compartment and the water meter compartment.

[0012] A further improvement to this technical solution is to install anti-tamper plugs in the screw holes corresponding to the screws used between the battery compartment and the water meter compartment.

[0013] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows:

[0014] This invention externalizes the battery of the ultrasonic water meter and achieves a modular structure design through the battery compartment. In use, different specifications of battery modules can be matched according to the usage situation, and battery replacement is simple and convenient.

[0015] This invention features a waterproof plug with a conical stepped structure and a rubber sealing ring at each step, improving waterproof performance.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] This utility model is an ultrasonic water meter with an external battery compartment, and the battery part of the ultrasonic water meter has been improved.

[0024] The ultrasonic water meter includes a water meter housing 1, within which the main body of the ultrasonic water meter is located. This invention externally mounts the battery of the ultrasonic water meter; a battery compartment 2 is also provided on the outer surface of the water meter housing 1, containing the battery. The battery compartment 2 and the water meter housing 1 are separate components.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the battery compartment 2 and the water meter compartment 1 are fixedly connected by screws to ensure a stable connection between them. Meanwhile, the batteries in the water meter compartment 1 and the battery compartment 2 are connected by a waterproof plug 3. In effect, the battery is electrically connected to the ultrasonic water meter inside the water meter compartment 1 via a wire leading out of the waterproof plug, thus enabling the battery to power the ultrasonic water meter.

[0026] This technical solution is an improvement on conventional ultrasonic water meters. The specific improvement involves externalizing the battery and adding an additional battery compartment. The meter consists of a water meter body and a battery compartment. This does not change the internal power supply method of the water meter; what changes is the battery insertion and connection method, which can be achieved by using a waterproof plug. It can be understood as moving the battery from inside the device to the outside, and connecting a wire to the original connector. One end of the wire connects to the power input terminal of the water meter, and the other end connects to a connector. This connector, through a matching connector, connects to the battery, which in turn connects to the battery via a wire. The original wiring connections from the battery to the inside of the ultrasonic water meter remain unchanged.

[0027] In this invention, the water meter compartment 1 and the battery compartment 2 are electrically connected using a plug and socket. Preferably, a socket is provided on the water meter compartment 1, which is electrically connected to the ultrasonic water meter; a waterproof plug 3 is provided on the battery compartment 2, which is electrically connected to the battery. Through the cooperation of the waterproof plug and the socket, the battery powers the ultrasonic water meter.

[0028] In this invention, to ensure safe and effective power supply to the ultrasonic water meter, the waterproof plug 3 is designed as a conical stepped structure, with a rubber sealing ring at each step. This improves waterproof performance and ensures that the fit between the plug and the socket is not affected by water or moisture. Furthermore, the waterproof plug 3 is typically designed as a three-step conical stepped structure, with a rubber sealing ring at each step. The three steps can be considered as a frustum of a cone structure, specifically as follows... Figure 2 , Figure 3 As shown.

[0029] In this utility model, the battery compartment 2 is fixedly installed on the surface of the water meter compartment 1, and a rubber sealing ring is also provided at the joint between the two, thus forming a total of four protective sealing rings, which improves the protection effect at the plug and avoids short circuit faults caused by water vapor entering.

[0030] In the specific implementation of this utility model, in order to ensure the overall safety of the ultrasonic water meter, the battery compartment 2 and the water meter body 1 are fixedly connected by screws. Anti-disassembly plugs are set at the screw holes corresponding to the screws, so that they cannot be removed without special tools and are disposable, reducing human damage to the battery.

[0031] This invention features a modular design for the battery of the ultrasonic water meter, allowing for the combination of different battery modules of varying specifications depending on the usage, and making battery replacement simple and convenient.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
