Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically a novel flow detection structure. Background Technology

[0002] With the advancement of smart city construction, smart water meters are playing an increasingly important role in water supply network monitoring and management. Traditional mechanical water meters can only measure water consumption, which is insufficient to meet the needs of modern water management. Currently, ultrasonic water meters exist, such as the flow sensor disclosed in patent number CN220187777U, which includes a pipe with a flow guide tube inside. Ultrasonic reflectors are installed at both ends of the flow guide tube, and ultrasonic transducers are installed on the outer surface of the pipe at the locations of the two reflectors, improving detection accuracy. However, pressure monitoring of the water supply network is crucial for its safe operation. Excessive water pressure can cause pipe bursts, while insufficient water pressure will affect normal water use. This water meter structure still cannot meet the pressure detection function. Utility Model Content

[0003] The purpose of this invention is to provide a novel flow detection structure to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a novel flow detection structure, comprising a main pipe for fluid passage and an ultrasonic detection component mounted on the main pipe. The ultrasonic detection component includes a transducer and a reflector. The main pipe includes a detection pipe section and a connecting pipe section coaxially arranged. The outlet end of the detection pipe section is connected to the inlet end of the connecting pipe section. A mounting body is provided on one side of the detection pipe section, and a mounting hole is provided in the mounting body. The end of the mounting hole is connected to the detection pipe section and extends to the outlet end. The mounting hole is used to accommodate a pressure sensor.

[0006] Furthermore, the axis of the mounting hole intersects the axis of the detection tube segment at an angle of less than 50°.

[0007] Furthermore, the top of the mounting hole is recessed inward to form a mounting groove, which is connected to the mounting hole, and the inner diameter of the mounting groove is larger than the inner diameter of the mounting hole.

[0008] Furthermore, the detection pipe section and the connecting pipe section are connected by threads.

[0009] Furthermore, the upper end of the detection tube segment is provided with two first mounting tubes and one second mounting tube. The upper ends of the first mounting tube and the second mounting tube are provided with mounting plates. The first mounting tube is used to accommodate the transducer, and the second mounting tube is used to accommodate the temperature sensor.

[0010] Furthermore, a valve is provided at the outlet end of the detection tube section to regulate the flow rate at the outlet end.

[0011] This utility model has the following beneficial effects:

[0012] This invention provides pressure detection functionality through the mounting body and its internal pressure sensor without affecting the accuracy of internal flow detection, providing important information for water supply scheduling, leakage detection, and equipment maintenance; at the same time, the pressure sensor is installed in a designated location, improving the accuracy of pressure detection.

[0013] This utility model facilitates maintenance and replacement by using a disassembly and assembly structure for the detection pipe section and connecting pipe section.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figures 1-3As shown, the novel flow detection structure in this embodiment conventionally consists of a main pipe through which fluid flows and an ultrasonic detection component (not shown in the figure) disposed on the main pipe. The ultrasonic detection component includes a transducer and a reflector, which form an ultrasonic detection path to detect the internal flow.

[0022] Specifically, the main body includes a detection tube section 10 and a connecting tube section 20 arranged coaxially. The liquid outlet end of the detection tube section 10 is connected to the liquid inlet end of the connecting tube section 20, and the detection tube section 10 and the connecting tube section 20 are connected by threads for easy disassembly and assembly.

[0023] The detection tube section 10 has two first mounting tubes 11 and one second mounting tube 12 vertically arranged at its upper end. The first mounting tubes 11 and the second mounting tube 12 are provided with mounting plates 13 at their upper ends. The first mounting tubes 11 are used to accommodate transducers, and the second mounting tubes 12 are used to accommodate temperature sensors. The second mounting tube 12 is located between the two first mounting tubes 11. All three are located between the liquid inlet end and the liquid outlet end of the detection tube section 10. The liquid inlet end and the liquid outlet end of the detection tube section 10 are provided with external threads or internal threads for threaded connection.

[0024] The mounting plate 13 is locked and fixed to the wall of the first mounting tube 11 by bolts or other fasteners.

[0025] Additionally, a mounting body 30 is provided on one side of the detection tube section 10. The mounting body 30 is horizontally positioned and has a mounting hole 31 inside. The end of the mounting hole 31 communicates with the detection tube section 10 and extends to the liquid outlet end. The mounting hole 31 is used to accommodate a pressure sensor (not shown in the figure). The axis of the mounting hole 31 intersects the axis of the detection tube section 10 with an angle of less than 50°. That is, the mounting hole 31 penetrates the inner wall of the detection tube section 10 and forms a detection hole position on the inner wall. The extension direction of the mounting hole 31 is towards the flow direction of the fluid in the detection tube section 10.

[0026] The top of the mounting hole 31 is recessed inward to form a mounting groove 32, which is connected to the mounting hole 31. The inner diameter of the mounting groove 32 is larger than the inner diameter of the mounting hole 31. The pressure sensor is installed in the mounting groove 32, and its detection end extends into the mounting hole 31, but there is a gap between it and the inner wall of the detection pipe section 10. Considering that the faster the flow velocity on the surface of an object, the lower the surface pressure will be, which will lead to inaccurate pressure detection, the accuracy of pressure detection can be improved by moving the detection point a certain distance away from the inside of the pipe.

[0027] The outlet end of the detection tube section 10 is equipped with a valve 40, which is used to adjust the flow rate at the outlet end.

[0028] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
