Description

Technical Field

[0001] This utility model relates to an ultrasonic metering sensor control box, specifically to an integrated control box for an M-type reflective ultrasonic metering circuit. Background Technology

[0002] Chinese patent discloses an ultrasonic water metering module structure and an ultrasonic water meter with application number CN201920093376.X. The ultrasonic water metering module structure includes a pipe section shell part and a metering pipeline part. The pipe section shell part includes a pipe section body, a shell set on the pipe section body, and two ultrasonic transducers. The metering pipeline part includes a reduced diameter pipe, a middle reflector, and two end reflectors. The reduced diameter pipe is set inside the pipe section body. The inner cavity of the reduced diameter pipe has a reduced diameter section and an expanded diameter section connected to both ends of the reduced diameter section. The pipe wall of the reduced diameter section has a middle reflector mounting hole, and a middle reflector is installed in the middle reflector mounting hole. Ultrasonic transducer mounting holes are opened on the pipe walls of the two expanded diameter sections and the pipe wall of the pipe section body at the corresponding positions. An end reflector is installed on the pipe wall of each of the two expanded diameter sections. An ultrasonic transducer is sealed and installed at the ultrasonic transducer mounting hole position on the pipe section body. The ultrasonic transducer, the middle reflector, and the end reflectors constitute a W-shaped acoustic pipeline structure.

[0003] Although the ultrasonic water metering module structure can achieve metering and detection, it still has the following drawbacks: because a middle reflector needs to be installed on the pipe wall of the reduced diameter section, and the middle reflector needs to be installed inside the pipe body, the installation process of the middle reflector is complicated, which greatly increases the number of installation steps and reduces production efficiency. Utility Model Content

[0004] This utility model provides an integrated control box for an M-type reflective ultrasonic metering circuit, which solves the problem of complicated installation steps caused by the need to install the reflector inside the pipe body in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses an integrated control box for an M-type reflective ultrasonic metering circuit, comprising: a box body, an ultrasonic transmitter, and an ultrasonic receiver. The box body is used to install on the ventilation pipeline to be tested. The ventilation pipeline to be tested has a slot, which is blocked by the box body. The box body has mounting holes communicating with the slot. There are at least two mounting holes. The ultrasonic transmitter is installed in one mounting hole, and the ultrasonic receiver is installed in the other mounting hole. The surface of the box body located in the slot forms a middle reflective surface, which is located between the ultrasonic transmitter and the ultrasonic receiver. The inner wall of the ventilation pipeline to be tested forms two edge reflective surfaces. One edge reflective surface is directly opposite the ultrasonic transmitter, and the other edge reflective surface is opposite the ultrasonic receiver. The edge reflective surface directly opposite the ultrasonic transmitter is used to reflect the ultrasonic waves emitted by the ultrasonic transmitter to the middle reflective surface, and the edge reflective surface directly opposite the ultrasonic receiver is used to reflect the ultrasonic waves reflected by the middle reflective surface to the ultrasonic receiver.

[0007] Preferably, a first clamping mechanism and a second clamping mechanism are installed inside the housing, and a step is formed in the mounting hole. The first clamping mechanism is used to clamp the ultrasonic transmitter by cooperating with a mounting hole, and the second clamping mechanism is used to clamp the ultrasonic receiver by cooperating with another mounting hole.

[0008] Preferably, the inner wall of the box protrudes to form a ring that communicates with the mounting hole, and the ring is connected to the first clamping mechanism or the second clamping mechanism.

[0009] Preferably, both the first pressing mechanism and the second pressing mechanism include: a surrounding ring, a middle pressing ring, and a protruding ring. The surrounding ring surrounds the outer ring, and the ring restricts the surrounding ring from detaching through friction. A protruding ring protrudes from the top of the surrounding ring, and a middle pressing ring protrudes from the inner wall of the bottom of the protruding ring. The middle pressing ring is used to press the ultrasonic transmitter or ultrasonic receiver onto the step.

[0010] Preferably, the box includes a body and a lid, with an opening formed on the side of the body away from the air duct to be tested, and the opening is closed by the lid.

[0011] Preferably, the inner wall of the lid protrudes to form a protrusion, which presses both the first and second pressing mechanisms onto the ring.

[0012] Preferably, the box body extends to form a latching arm on the side near the air duct to be tested, and the latching arm engages with the air duct to be tested.

[0013] Preferably, the ventilation pipe to be tested protrudes at the position where it is in close contact with the box body to form a connecting block, and the connecting block engages with the snap-fit ​​arm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This application breaks with the traditional approach (where the intermediate reflective surface is placed inside the venting pipe under test). Instead, the intermediate reflective surface is designed on the housing, formed during the injection molding process. Simultaneously, a slot is directly cut into the venting pipe under test, allowing both the mounting hole outlet and the intermediate reflective surface to extend into it. This slot is fully sealed by the housing, preventing gas leakage from the venting pipe. Thus, when the housing is snapped together, the intermediate reflective surface can be installed directly onto the venting pipe, reducing the steps required to install the component with the intermediate reflective surface inside the venting pipe and improving installation efficiency.

[0016] Other advantages, objectives and features of this invention will be apparent in part from the following description, and in part from the understanding of those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4As shown, this utility model discloses an integrated control box for an M-type reflective ultrasonic metering circuit, including: a box body 1, an ultrasonic transmitter 2, and an ultrasonic receiver 3. The box body 1 is used to install on the ventilation pipe 4 to be tested. The ventilation pipe 4 to be tested has a slot, which is blocked by the box body 1. The box body 1 has mounting holes communicating with the slot. There are at least two mounting holes. The ultrasonic transmitter 2 is installed in one mounting hole, and the ultrasonic receiver 3 is installed in the other mounting hole. The surface of the box body 1 located in the slot forms an intermediate reflective surface 10, which is located between the ultrasonic transmitter 2 and the ultrasonic receiver 3. The inner wall of the ventilation pipe 4 to be tested forms two edge reflective surfaces 40. One edge reflective surface 40 is directly opposite the ultrasonic transmitter 2, and the other edge reflective surface 40 is directly opposite the ultrasonic receiver 3. The edge reflective surface 40 directly opposite the ultrasonic transmitter 2 is used to reflect the ultrasonic waves emitted by the ultrasonic transmitter 2 to the intermediate reflective surface 10, and the edge reflective surface 40 directly opposite the ultrasonic receiver 3 is used to reflect the ultrasonic waves reflected by the intermediate reflective surface 10 to the ultrasonic receiver 3. The entire ultrasound path presents an M-shaped pattern.

[0024] In this application, a first clamping mechanism 51 and a second clamping mechanism 52 are installed inside the housing 1. A step is formed in the mounting hole. The first clamping mechanism 51 is used to clamp the ultrasonic transmitter 2 by cooperating with one mounting hole, and the second clamping mechanism 52 is used to clamp the ultrasonic receiver 3 by cooperating with another mounting hole. The design of the first clamping mechanism 51 and the second clamping mechanism 52 positions the ultrasonic transmitter 2 and the ultrasonic receiver 3.

[0025] Preferably, the inner wall of the housing 1 protrudes to form a ring 11 that communicates with the mounting hole. The ring 11 connects to either the first clamping mechanism 51 or the second clamping mechanism 52. The design of the ring 11 provides a mounting base for the first clamping mechanism 51 and the second clamping mechanism 52.

[0026] In this application, both the first clamping mechanism 51 and the second clamping mechanism 52 include: a surrounding ring 511, a middle clamping ring 512, and a protruding ring 513. The surrounding ring 511 surrounds the circular ring 11, and the circular ring 11 restricts the surrounding ring 511 from detaching through friction. A protruding ring 513 protrudes from the top of the surrounding ring 511, and a middle clamping ring 512 protrudes from the inner wall of the bottom of the protruding ring 513. The middle clamping ring 512 is used to press the ultrasonic transmitter 2 or ultrasonic receiver 3 onto the step. The surrounding ring 511 and the circular ring 11 are initially positioned by friction. After the initial positioning, the ultrasonic transmitter 2 and the ultrasonic receiver 3 will not detach, facilitating connection to the circuit board inside the housing 1. The ultrasonic transmitter 2 and the ultrasonic receiver 3 are electrically connected to the circuit board. The middle clamping ring 512 has the function of restricting the ultrasonic transmitter 2 or the ultrasonic receiver 3 from detaching from the mounting hole. The protruding ring 513 has a through hole for the wires on the ultrasonic transmitter 2 or the ultrasonic receiver 3 to pass through.

[0027] In this application, the housing 1 includes a main body and a cover (not shown in the figure). The main body has an opening on the side facing away from the venting pipe 4 to be tested, and the opening is fastened by the cover. The main body and the cover are connected by screws, allowing the circuit board to be viewed after opening the cover of the housing 1.

[0028] Preferably, the inner wall of the lid protrudes to form a convex part (not shown in the figure), which presses both the first pressing mechanism 51 and the second pressing mechanism 52 onto the ring 11. When the lid is closed, the convex part presses against the protruding ring 513, and the lid fully positions the first pressing mechanism 51 and the second pressing mechanism 52, preventing the ultrasonic transmitter 2 and the ultrasonic receiver 3 from separating during transportation or other processes.

[0029] In this application, the housing 1 extends to form a latching arm 12 on the side near the air duct 4 to be tested, and the latching arm 12 engages with the air duct 4 to be tested. This allows the housing 1, ultrasonic transmitter 2, ultrasonic receiver 3, and intermediate reflective surface 10 to be installed together on the air duct 4 to be tested, and installation can be achieved by pressing, thus improving installation efficiency.

[0030] Preferably, the ventilation pipe 4 to be tested protrudes from the position where it is in close contact with the housing 1 to form a connecting block 41, which engages with the latching arm 12. The design of the connecting block 41 facilitates the latching connection with the latching arm 12. The connection between the latching arm 12 and the housing 1 has a certain degree of elasticity, making the connection between the ventilation pipe 4 to be tested and the housing 1 easier.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
