Description

Technical Field

[0001] This utility model relates to the field of bubble detection technology, and in particular to a bubble sensor and pipeline assembly. Background Technology

[0002] Ultrasonic bubble sensors, as key devices for detecting bubbles in liquid circuits, operate based on the characteristic that ultrasound propagates significantly less in gaseous media (such as air) than in liquid media. During operation, the sensor's transmitter and receiver are tightly fitted to opposite sides of the pipe's outer wall. The ultrasonic waves emitted by the transmitter penetrate the pipe wall and the internal liquid, and are received by the receiver. When bubbles are present in the liquid circuit, the ultrasonic waves experience strong attenuation, reflection, or refraction as they pass through the bubble region, causing a significant reduction or disappearance of the ultrasonic signal intensity detected by the receiver. The sensor identifies the presence of bubbles by recognizing this abrupt change in signal intensity. However, traditional ultrasonic bubble sensors typically employ a fixed, non-adjustable pipe clamping spacing design, which severely limits their adaptability to pipes of different diameters, resulting in poor versatility.

[0029] The following is combined Figure 1 and Figure 2 This invention describes a bubble sensor and piping assembly provided by an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0030] An embodiment of the first aspect of this utility model provides a bubble sensor, such as... Figure 1 and Figure 2As shown, it includes: a fixed part 100; a movable part 200, which is slidably connected to the fixed part 100 via a sliding connection assembly, and a pipe clamping area 300 is formed between the movable part 200 and the fixed part 100, the sliding connection assembly being used to adjust the size of the pipe clamping area 300; an ultrasonic transmitting unit 400, which is disposed on one of the fixed part 100 and the movable part 200; and an ultrasonic receiving unit 500, which is disposed on the other of the fixed part 100 and the movable part 200, and the ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500 are correspondingly disposed.

[0031] The bubble sensor provided by this utility model includes a fixed part 100, a movable part 200, an ultrasonic transmitting unit 400, and an ultrasonic receiving unit 500. The movable part 200 is slidably connected to the fixed part 100 via a sliding connecting assembly, and a pipe clamping area 300 is formed between the movable part 200 and the fixed part 100. The sliding connecting assembly is used to adjust the size of the pipe clamping area 300. The ultrasonic transmitting unit 400 is disposed on one of the fixed part 100 and the movable part 200. The ultrasonic receiving unit 500 is disposed on the other of the fixed part 100 and the movable part 200, and the ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500 are correspondingly disposed.

[0032] As described above, by employing a design that slides between the fixed part 100 and the movable part 200, and in conjunction with the corresponding ultrasonic transmitting unit 400 and ultrasonic receiving unit 500 mounted on both, the bubble sensor achieves flexible adjustment of the size of the pipe clamping area 300. This allows the bubble sensor to adapt to pipes of different diameters, significantly improving the product's versatility and applicability.

[0033] In one embodiment of the present invention, the fixing part 100 includes: a base 110; a fixing housing 120, the fixing housing 120 being disposed on the base 110 and having a first mounting position on the fixing housing 120, the first mounting position being located on the side near the movable part 200, the first mounting position being used to mount one of the ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500; and a support plate 130, the support plate 130 being disposed on the base 110 and being located between the first mounting position and the movable part 200.

[0034] In another embodiment of the present invention, the movable part 200 includes: a movable housing 210, which is slidably connected to the base 110 via a sliding connection assembly. A second mounting position is provided on the movable housing 210, which is opposite to the first mounting position. The second mounting position is used to mount the other of the ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500.

[0035] The area on the support plate 130 between the first mounting position and the second mounting position is the pipe clamping area 300; the sliding connection assembly can drive the movable housing 210 to slide so that the second mounting position moves closer to or further away from the first mounting position.

[0036] Furthermore, in another embodiment of this utility model, the sliding connection assembly includes: a first connecting plate 610, which is connected to the base 110; a second connecting plate 620, which is connected to the base 110 and spaced apart from the first connecting plate 610; a lead screw 630, which is arranged along a sliding direction parallel to the movable housing 210, with its first end connected to the second connecting plate 620 and its second end passing through one side of the first connecting plate 610 to the other side; a slider 640, which is threadedly connected to the lead screw 630 and connected to the movable housing 210; and a driving member 650, which is connected to the second end of the lead screw 630 and used to drive the lead screw 630 to rotate.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the base 110 has a plate structure. In this embodiment, the left side of the base 110 is connected to the fixed housing 120. The middle of the base 110 is connected to the first connecting plate 610, and the right side of the base 110 is connected to the second connecting plate 620. The support plate 130 is supported and connected to the upper end of the first connecting plate 610. The right side wall of the fixed housing 120 is fixedly overlapped with the left edge of the support plate 130, and the first mounting position is located on the right side wall of the fixed housing 120. A second mounting position is provided on the left side wall of the movable housing 210, and the movable housing 210 can be movably overlapped with the support plate 130. The first mounting position and the second mounting position are arranged opposite to each other. For example, an ultrasonic transmitting unit 400 is installed at the first mounting position, and an ultrasonic receiving unit 500 is installed at the second mounting position. The ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500 are arranged opposite to each other and aligned. A lead screw 630 is rotatably connected between the first connecting plate 610 and the second connecting plate 620. A slider 640 is connected to the lead screw 630. The slider 640 is connected to the movable housing 210. The right end of the lead screw 630 extends to the outside of the second connecting plate 620 and is connected to the drive member 650.

[0038] In use, the rotary drive 650 drives the lead screw 630 to rotate. During the rotation of the lead screw 630, the slider 640 can move along the axis of the lead screw 630. Consequently, the slider 640 drives the movable housing 210 to move on the support plate 130 in a direction away from or towards the fixed housing 120. This allows the size of the pipe clamping area 300 between the first mounting position and the second mounting position on the support plate 130 to be changed to accommodate pipes of different diameters.

[0039] In one embodiment of the present invention, the sliding connection assembly further includes a guide rod 660, which is connected between the slider 640 and the first connecting plate 610 and is used to provide sliding guidance for the slider 640.

[0040] like Figure 2 As shown, the guide rod 660 is arranged along the axis parallel to the lead screw 630. One end of the guide rod 660 is fixedly connected to the second connecting plate 620, and a guide hole is provided on the slider 640. The other end of the guide rod 660 passes through one side of the slider 640 to the other side to provide guidance when the slider 640 slides.

[0041] In one embodiment of this utility model, the driving component 650 includes: a manual adjustment dial 651, which is connected to a lead screw 630; and a locking screw 652, which is threadedly connected to the manual adjustment dial 651. The end of the locking screw 652 can abut against the first connecting plate 610 to lock the manual adjustment dial 651, or the end of the locking screw 652 can separate from the first connecting plate 610 to unlock the manual adjustment dial 651.

[0042] For example, such as Figure 2 As shown, the manual adjustment dial 651 is connected to the outer end of the lead screw 630. By rotating the lead screw 630 forward or backward, the slider 640 moves the movable housing 210 closer to or further away from the fixed housing 120, thereby changing the size of the pipe clamping area 300. A threaded hole is provided on the manual adjustment dial 651. A locking screw 652 can be screwed into the threaded hole. By adjusting the insertion depth of the locking screw 652, the end of the locking screw 652 can press against the first connecting plate 610, or separate from the first connecting plate 610. When the end of the locking screw 652 presses against the first connecting plate 610, the manual adjustment dial 651 can be locked, so that the movable housing 210 is reliably held in its current position, improving the stability of the bubble sensor operation.

[0043] In one embodiment of this utility model, such as Figure 2 As shown, the sliding connection assembly further includes: a first bearing 670, which is connected between the first connecting plate 610 and the lead screw 630; and a second bearing 680, which is connected between the second connecting plate 620 and the lead screw 630.

[0044] In one embodiment of this utility model, such as Figure 2 As shown, a receiving cavity 121 is provided inside the fixed housing 120. The bubble sensor also includes a circuit board 700, which is disposed inside the receiving cavity 121 and is connected to the ultrasonic transmitting unit 400 and the ultrasonic receiving unit 500.

[0045] In another embodiment of the present invention, the ultrasonic transmitting unit 400 includes: a first piezoelectric ceramic, which is disposed in one of a first mounting position and a second mounting position; the ultrasonic receiving unit 500 includes: a second piezoelectric ceramic, which is disposed in the other of the first mounting position and the second mounting position.

[0046] A second aspect of this utility model provides a pipeline assembly, including: a bubble sensor as described above; and a pipeline body clamped in a pipeline clamping region 300 between a fixed part 100 and a movable part 200.

[0047] Furthermore, the pipeline assembly provided by this utility model, since it includes the bubble sensor as described above, also possesses the advantages described above.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
