Description

Technical Field

[0001] The utility model relates to the technical field of steam pipeline monitoring, and more specifically to a steam pipeline displacement monitoring device. Background Art

[0002] The steam produced by the boiler is transported to the steam-using equipment through metal pipes. The length of the steam pipe depends on the distance between the boiler and the steam-using equipment. Due to the thermal expansion and contraction of metal pipes, when the steam pressure and temperature in the pipes change, the pipes will deform to varying degrees. If the deformation is too large, it may cause steam leakage or even pipe burst, affecting factory production. In serious cases, it may cause safety accidents.

[0003] Due to factors such as factory output, monthly holidays, and different steam pressure requirements during the day and night, the steam pipes often expand and contract due to heat. In order to avoid deformation damage caused by thermal expansion and contraction of the pipes, expansion joints are installed on the steam pipes, which can reduce pipe displacement and absorb pipe thermal stress to a certain extent. However, since the factory boilers are far away from the steam-using equipment and the steam pipes are long, it is difficult for operators to monitor the pipe deformation in real time. Although operators also regularly inspect the pipes, it is difficult to detect minor deformations of the pipes, which are often only discovered when the pipes are significantly displaced or fall off the pipe rack.

[0004] As the core pressure-bearing component in the boiler steam-water piping system, the safety of the steam pipe is crucial to the factory's production and supply. Due to deviations in the design, manufacturing, installation, and operation stages, there is a common phenomenon that the steam pipe is abnormally displaced due to thermal expansion and contraction. Since the harm caused by abnormal thermal expansion and displacement of the pipe is often a slow accumulation process, it is not easy to attract the attention of the operator, and there are major safety hazards. In order to ensure the safe operation of the steam pipe and its connected equipment, it is usually necessary to monitor the displacement of the steam pipe so that an early warning can be issued when the displacement of the steam pipe exceeds the limit value.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0032] according to Figure 1 As shown, the utility model provides a steam pipeline displacement monitoring device, including a frame 1, a steam pipeline 3 and a monitoring component;

[0033] A support plate 2 is provided on the frame 1, and a steam pipe 3 is placed on the support plate 2;

[0034] The monitoring component includes a radial monitoring component and an axial monitoring component; the radial monitoring component includes a radial sensor 5 and a radial ranging baffle 4, the radial sensor 5 is arranged on the steam pipe 3, the radial ranging baffle 4 is arranged on the frame 1 and is opposite to the radial sensor 5, the radial sensor 5 can emit infrared signals radially along the steam pipe 3, and the infrared signals are received by the radial sensor 5 after being reflected by the radial ranging baffle 4.

[0035] The axial monitoring assembly includes an axial sensor 8 and an axial ranging baffle 7. The axial sensor 8 is arranged on the steam pipe 3. The axial ranging baffle 7 is arranged on the frame 1 and is opposite to the axial sensor 8. The axial sensor 8 can emit infrared signals along the axial direction of the steam pipe 3. The infrared signals are received by the axial sensor 8 after being reflected by the axial ranging baffle 7.

[0036] The utility model mainly solves the problem of how to quantify the tiny deformation of the steam pipe 3 and monitor the status in real time. A set of displacement monitoring device is installed on the basis of the steam pipe 3 equipped with an expansion joint. The device can monitor the axial and radial deformation of the pipeline in real time, quantify the tiny deformation, and improve the inspection efficiency of personnel and the safety of equipment.

[0037] Further, the frame 1 is composed of two columns, the tops of the columns are fixedly connected by a connecting rod, and both columns are provided with a supporting plate 2. The supporting plate 2 is a U-shaped structure, and the U-shaped opening of the supporting plate 2 is arranged upward.

[0038] In this embodiment, the steam pipe 3 is supported by multiple support plates 2, and the U-shaped support plate 2 can limit the steam pipe 3. Rubber pads and other structures can be set on the inner side of the support plate 2 to reduce the friction between the steam pipe 3 and the support plate 2 when the steam pipe 3 is displaced.

[0039] Furthermore, the radial distance measuring baffle 4 is arranged on the connecting rod and is parallel to the steam pipe 3 . The radial sensor 5 is arranged on the steam pipe 3 through a first bracket, and the first bracket is perpendicular to the axis of the steam pipe 3 .

[0040] The radial sensor 5 is installed on the steam pipe 3 without a fulcrum through the first bracket, and emits infrared signals radially along the steam pipe 3. The infrared signals are received by the sensor after being reflected by the radial ranging baffle 4. The distance between the steam pipe 3 and the radial ranging baffle 4 is calculated by measuring the time difference between the emission and reception of the infrared signals. If this distance changes, it means that the pipe has been deformed or offset in the radial direction.

[0041] Furthermore, a first alarm 6 is provided on the first bracket. The first alarm 6 is an audible and visual alarm and is electrically connected to the radial sensor 5. When the radial sensor 5 detects that the radial displacement of the steam pipe 3 exceeds a limit value, the first alarm 6 automatically flashes and emits an alarm sound to remind the operator.

[0043] The second bracket is in an L-shaped structure, and the vertical side of the second bracket is perpendicular to the steam pipe 3, and the horizontal side is parallel to the steam pipe 3. The axial sensor 8 is arranged at the end of the horizontal side of the second bracket.

[0044] In this embodiment, the axial sensor 8 is installed on the steam pipe 3 near the fulcrum through the second bracket, and an infrared signal is emitted axially along the steam pipe 3. The infrared signal is received by the sensor after being reflected by the axial ranging baffle 7. The distance between the steam pipe 3 and the axial ranging baffle 7 is calculated by measuring the time difference between the emission and reception of the infrared signal. If this distance changes, it means that the pipe has been displaced in the axial direction.

[0045] Furthermore, a second alarm 9 is provided on the second bracket. The second alarm 9 is an audible and visual alarm and is electrically connected to the axial sensor 8. When the axial sensor 8 detects that the axial displacement of the steam pipe 3 exceeds a limit value, the second alarm 9 automatically flashes and emits an alarm sound to remind the operator.

[0046] By real-time monitoring of the above two distances, the displacement of the steam pipe 3 can be monitored in real time. On this basis, certain limits are set for the two distances. When the distance exceeds the limit, the alarm light flashes immediately to remind the operator that the deformation is too large and needs to be checked in time to avoid equipment damage.

[0047] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
