Claims

1. A pipeline leak monitoring apparatus, characterized by, include: A sleeve (2) and two sealing elements (3) are provided. The sleeve (2) is used to be fitted over the pipe (1). One of the sealing elements (3) is connected to one end of the sleeve (2) and the pipe (1), and the other sealing element (3) is connected to the other end of the sleeve (2) and the pipe (1). The sleeve (2), the pipe (1) and the two sealing elements (3) form an annular space. The detection component is provided with a detection port on the side wall of the sleeve (2) that communicates with the annular space. The detection component is disposed at the detection port and is used to detect leaking fluid in the annular space.

2. The pipe leak monitoring apparatus of claim 1, wherein, The detection assembly includes a detector (4) and a support tube (5), one end of the support tube (5) is connected to the detection port, and the detector (4) is disposed at the other end of the support tube (5).

3. A pipeline leak monitoring apparatus according to claim 2, wherein, The support tube (5) includes a support section (51) and a first bending section (52). One end of the support section (51) is connected to one end of the first bending section (52), and the other end of the support section (51) is connected to the detection port. The detector (4) is located at the other end of the first bending section (52). The support tube (5) is perpendicular to the horizontal plane, and the first bent section (52) is parallel to the horizontal plane.

4. The pipe leak monitoring apparatus of claim 3, wherein, The support tube (5) further includes a second bend section (53), one end of which is connected to the other end of the first outer bend section. The detector (4) is located at the other end of the second bend section (53). The second bend section (53) is perpendicular to the horizontal plane, and the other end of the second bend section (53) is closer to the sleeve (2) than the first bend section (52).

5. A pipeline leak monitoring apparatus according to any one of claims 1 to 4, wherein, The pipeline leakage monitoring device also includes an alarm device connected to the detection component. The alarm device is used to issue an alarm when the detection component detects the presence of leaking fluid in the annular space.

6. The pipe leak monitoring apparatus of claim 5, wherein, The alarm device includes a signal propagation alarm, an audible alarm, and a visual alarm.

7. A pipeline leak monitoring apparatus according to any one of claims 1 to 4, wherein, The pipeline leakage monitoring device also includes a support (6), which is supported at the bottom of the sleeve (2).

8. The pipe leak monitoring apparatus of claim 7, wherein, The pipeline leakage monitoring device also includes an isolation element (7), which is disposed between the support element (6) and the sleeve (2), and the isolation element (7) is an elastic element.

9. A pipeline leak monitoring apparatus according to any one of claims 1 to 4, wherein, The sealing component (3) includes a sealing plate with an opening. The outer periphery of the sealing plate is connected to the end of the sleeve (2). The wall of the opening is connected to the pipe (1). The axis of the opening coincides with the axis of the sleeve (2).

10. A pipeline leak monitoring apparatus according to any one of claims 1 to 4, wherein, The dimension of the annular space perpendicular to the axial direction of the sleeve (2) is 3-6 cm.
