Description

Technical Field

[0001] This utility model relates to the field of ultrasonic water meter technology, and in particular to a stainless steel ultrasonic water meter housing. Background Technology

[0002] Ultrasonic water meters are a type of water meter that uses the propagation speed of ultrasonic waves in water to measure water flow. They are widely used due to their accurate flow measurement. Ultrasonic water meters typically have a transducer and communication device installed on the meter casing for measurement purposes. Currently used transducer mounting brackets are usually welded directly to the cylindrical meter casing body with an arc-shaped bottom surface, and the transducer is then installed inside.

[0003] However, the transducer mounting bases currently in use are all solid structures except for the central transducer mounting area, which leads to material waste and increased costs. Furthermore, the original structure has voids because the transducer is mounted far from the main body of the watch case, resulting in measurement errors. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a stainless steel ultrasonic water meter housing.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A stainless steel ultrasonic water meter housing includes a housing body; four transducer mounting seats are symmetrically arranged on the housing body; the water-contacting surface of each transducer mounting seat is an arc-shaped surface that conforms to the arc of the housing body; each transducer mounting seat contains two mounting columns, the bottom of which extends out of the bottom surface of the transducer mounting seat and inserts into the housing body; each transducer mounting seat has two caps at its top to prevent lead wires from being exposed, the caps being located directly above the mounting columns; each transducer mounting seat also has a wire passage located between the caps and the mounting columns; and a lead wire port is provided on one side of each transducer mounting seat.

[0007] Furthermore, the main body of the watch case is provided with a communication equipment mounting base for installing communication equipment; the four transducer mounting bases are located on both sides of the communication equipment mounting base; a wire conduit is provided on one side of the transducer mounting base; one end of the wire conduit is connected to the lead-in port inside the transducer mounting base, and the other end is connected to the communication equipment mounting base.

[0008] Furthermore, a threaded fixing hole for fixing is provided in the middle position of the plug.

[0009] Furthermore, flanges for connecting external pipes are provided at both ends of the main body of the watch case.

[0010] Furthermore, a pressure sensor and a temperature sensor are also provided on the main body of the watch case; both the pressure sensor and the temperature sensor are installed in the communication equipment mounting base.

[0011] Furthermore, a transducer is provided inside the mounting column; a pressure ring for pressing the transducer is provided above the transducer; and a sealing ring is also provided between the transducer and the mounting column.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) This utility model sets an installation column in the transducer mounting base, and the transducer is directly assembled in the installation column. The rest of the transducer mounting base is a cavity design and no additional solid structure design is required. This simplifies the structure, makes the processing simple and quick, and reduces the manufacturing cost.

[0014] (2) The mounting column of this utility model is directly inserted into the inside of the main body of the watch case. This structural arrangement allows the transducer to be closer to the pipe of the main body of the watch case, so that there is no gap between the transducer and the pipe, thereby making the measurement results more accurate.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. 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.

[0029] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] Example 1

[0031] like Figures 1-5 As shown, a stainless steel ultrasonic water meter housing includes a housing body 1; flanges 9 for connecting external pipes are provided at both ends of the housing body 1, and four transducer mounting seats 2 are symmetrically arranged on the housing body 1; the water-contacting surface of the transducer mounting seat 2 is an arc-shaped surface that fits into the arc shape of the housing body 1, which can fit and weld well to the housing body 1 to prevent water leakage; each transducer mounting seat 2 is provided with two mounting columns 3, and the bottom of the mounting columns 3 extends out to provide transducer mounting... The bottom surface of the mounting base 2 is inserted into the interior of the main body 1 of the watch case. The transducer 13 is directly assembled into the mounting column 3. A pressure ring 14 is provided above the transducer 13 to press it down. A sealing ring 15 is also provided between the transducer 13 and the mounting column 3 to seal and prevent water leakage. The rest of the transducer mounting base 2 is a hollow design without any additional solid structure design, which simplifies the structure, makes processing simple and quick, reduces manufacturing costs, and allows the transducer 13 to be further away from the pipes of the main body 1 of the watch case. The proximity design ensures there are no gaps between the transducer 13 and the pipe, resulting in more accurate measurement results. Each transducer mounting base 2 has two caps 4 on its top, located directly above the mounting column 3, to prevent exposed leads. Each cap 4 has a threaded fixing hole 8 in the middle for fixing the transducer 13 after assembly. A wire passage 5 is also provided inside the transducer mounting base 2, located between the caps 4 and the mounting column 3. The main body 1 of the meter housing has a communication equipment mounting base 6 for mounting communication equipment. The four transducer mounting bases 2 are located on both sides of the communication equipment mounting base 6. One side of each transducer mounting base 2 has a lead-in port 12. Another side of each transducer mounting base 2 has a wire passage pipe 7. One end of the wire passage pipe 7 connects to the lead-in port 12, and the other end connects to the communication equipment mounting base 6. After the transducer 13 is assembled into the mounting column 3, the lead of the transducer 13 passes through the wire passage 5 and then through the wire passage pipe 7 to connect to the communication equipment inside the communication equipment mounting base 6.

[0032] like Figure 6 As shown, a pressure sensor 10 and a temperature sensor 11 are also provided; both the pressure sensor 10 and the temperature sensor 11 are installed in the communication equipment mounting base 6.

[0033] Example 2

[0034] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the pressure sensor 10 is set outside the communication equipment mounting base 6. Both of these pressure sensor 10 installation methods are acceptable, but in actual manufacturing, only one type of pressure sensor 10 will be installed as needed, and they will not coexist on the same ultrasonic water meter housing.

[0035] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
