Description

Technical Field

[0001] The utility model relates to the technical field of pipeline safety, in particular to a prefabricated direct-buried thermal insulation pipe leakage detection and alarm device. Background Art

[0002] Prefabricated direct buried insulated pipes are widely used in various piping systems such as heating and cooling. Their thermal insulation performance and safety are crucial to the stable operation of the entire system. However, since the pipes are buried underground for a long time, they are susceptible to multiple factors such as geological changes and corrosion, and are prone to leakage. Once leakage occurs, it not only affects the efficiency of the system, but may also cause environmental pollution and safety hazards. Therefore, an effective leak detection alarm device is needed to monitor the integrity of the pipeline in real time.

[0003] A Chinese patent with publication number CN217806329U discloses a prefabricated direct-buried insulated pipe leak detection and alarm device, which includes a metal inner tube and an insulation layer. An end cap is clamped at one end of the metal inner tube, and a plurality of groups of connecting sleeve rods are fixedly connected to one end of the end cap. A chamber is opened at one end of the connecting sleeve rod, and a movable block is movably arranged in the connecting sleeve rod chamber. A connecting plate is elastically connected to one end of the connecting sleeve rod, and a plurality of circular grooves are opened at one end of the connecting plate, and the diameter size of the circular groove is gap-matched with the maximum diameter size of the connecting sleeve rod. A spring is fixedly connected to one end of the inner wall of the circular groove of the connecting plate, and the other end of the spring is fixedly connected to the movable block. The patent has a simple structure, a reasonable arrangement, and is practical.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device clamps one end of the metal inner tube into the annular groove and provides elastic rubber buffer layers on both sides of the annular groove to protect the end of the metal inner tube from non-axial collisions. However, there are uncertainties during transportation, and it is necessary to perform leak detection operations on the delivered insulation pipes to avoid damage and cracks in the insulation pipes during transportation, which may cause danger during the use of the insulation pipes. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a prefabricated direct-buried insulated pipe leak detection alarm device. The device sets up the pipeline between an arc-shaped bracket and a ring-shaped bracket, and detects the external insulation layer through a detection ring. The detection ring moves back and forth with an electric slider, and can completely detect the pipeline. The electric telescopic rod drives an ultrasonic detector to detect the inside of the pipeline, and can detect whether there are cracks on the inner wall of the pipeline, thereby avoiding possible danger during the use of the pipeline.

[0008] In some embodiments, a pair of support seats are fixedly mounted with support columns, one of which is fixedly connected to an arc-shaped bracket, and the other is fixedly connected to an annular bracket, and a threaded rod is threadedly connected to the annular bracket.

[0009] In some embodiments, a pipe is placed between the arc-shaped bracket and the annular bracket, threads are provided on the outer peripheral wall at one end and the inner wall at the other end of the pipe, and a heat-insulating layer is fixedly installed on the pipe.

[0010] In some embodiments, a support plate is fixedly mounted on the bottom plate, an electric telescopic rod is fixedly connected to the support plate, and an ultrasonic detector is fixedly connected to one end of the electric telescopic rod.

[0011] In some embodiments, a display panel is fixedly mounted on the bottom plate, the display panel is electrically connected to the detection probe, and the display panel is electrically connected to the ultrasonic detector.

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

[0013] First, the utility model is provided with threads on the outer wall of one end of the pipe and the inner wall of the other end, so that the pipes after the inspection can be connected to form a whole and buried in the corresponding position. After the pipe is fixed, the electric slider drives the inspection ring to move back and forth, so that the insulation layer outside the pipe can be inspected. The multiple inspection probes inside the inspection ring are arranged in a ring shape, so that the entire insulation layer can be fully inspected.

[0014] Secondly, the utility model can extend the ultrasonic detector into the inside of the pipeline through the electric telescopic rod on the support plate, and can detect whether there are cracks inside the pipeline.
