Description

Technical Field

[0001] This utility model relates to the field of pipeline thermal displacement detection technology, specifically to a pipeline thermal displacement detection and early warning device. Background Technology

[0002] The hazards of thermal displacement in pipelines mainly include the following aspects:

[0003] 1. Abnormal thermal expansion displacement of pipelines can alter the normal thermal expansion displacement state of pipelines, creating abnormal constraints on the pipelines, increasing secondary stress on the pipelines, and potentially causing direct damage to the pipelines, affecting their lifespan and safe operation.

[0004] 2. Abnormal thermal expansion displacement of pipelines can also lead to a redistribution of load at the support points, increasing the load on local pipe sections and raising the primary stress in those sections. This can cause overload or unload of supports and hangers, or even their failure, further exacerbating the abnormal thermal expansion displacement and creating a vicious cycle.

[0005] 3. Abnormal thermal expansion displacement of pipelines can affect the thrust and torque exerted by the pipeline on the equipment, changing the maximum value of the thrust and torque at the pipeline port under working and cold conditions. This may exceed the equipment's bearing capacity, affecting the normal operation and safety of the equipment. Utility Model Content

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-4 As shown, a pipeline thermal displacement detection and early warning device includes a first flange 1 and a second flange 2 equidistantly arranged on a heat pipe 10, wherein:

[0031] A displacement scale 3 is fixedly installed on the side wall of the first flange 1;

[0032] A mounting plate 4 is fixedly installed on the side wall of the second flange 2, and the detection end of the sensor 5 fixedly installed on the mounting plate 4 faces the lower surface of the displacement scale 3.

[0033] Specifically, the above embodiment also includes an alarm installed on the mounting plate 4. The alarm is electrically connected to the sensor 5. When the sensor 5 moves with the heat pipe 10 and is displaced from the default position originally corresponding to the displacement scale 3, the alarm circuit is closed and an early warning is activated. The specific position and length of the heat pipe 10 movement are determined by observing the position of the sensor 5 and the displacement scale 3.

[0034] The alarm is powered by a continuous and stable supply of electricity via solar panels.

[0035] Furthermore, the sensor 5 in the above embodiments can be an infrared sensor, a Hall sensor, or a displacement sensor, or any other electronic component known to those skilled in the art.

[0036] In the above technology, after determining that the heat pipe 10 has reached its maximum displacement, the first flange 1 and the second flange 2 are fixed respectively. Then, the displacement scale 3 and the sensor 5 are connected. When the detection surface of the sensor 5 is displaced from the displacement scale 3, the sensing result is transmitted to the alarm, thereby realizing pipeline thermal displacement detection and early warning.

[0037] It should be noted that the electronic components and electronic control programs in the above embodiments are common knowledge to those skilled in the art, and therefore will not be described in detail.

[0038] As a further embodiment of this utility model, the displacement scale 3 is provided with spaced concave protrusions 31, the inner arc surface of which faces the detection end of the sensor 5.

[0039] Furthermore, in combination Figure 4 As shown. The sensor 5 includes a mounting base 51, and a ball 52 is slidably disposed at the detection port of the mounting base 51. The ball 52 is pushed by equidistant springs 53 disposed inside the mounting base 51 and always fits against the lower surface of the displacement scale 3.

[0040] A guide post 521 is fixedly installed on the sphere 52, and the guide post 521 is located inside the guide sleeve 511 fixedly installed on the inner wall of the mounting base 51;

[0041] A first brass guide block 522 is symmetrically arranged on the guide post 521, and a second brass guide block 512 symmetrically arranged on the inner wall of the guide sleeve 511 contacts the ball 52 and the displacement scale 3, which is the horizontal plane where the first brass guide block 522 is located.

[0042] It should be noted that, in combination Figure 2 As shown, in the default state, the sphere 52 is located inside the concave protrusion 31 on the displacement scale 3.

[0043] Furthermore, the threaded end of the aforementioned mounting base 51 passes through the through hole opened on the mounting plate 4 and is fixed by a nut threaded on the threaded end.

[0044] Specifically, in the above embodiment, when the heat pipe 10 expands and shifts due to thermal expansion, as the sensor 5 moves accordingly, the ball 52 on the sensor 5 moves against the lower surface of the displacement scale 3. As it moves, when the first concave protrusion 31 moves to the surface of the displacement scale 3, the first brass guide block 522 contacts the first brass guide block 522. The sensing result at this time is transmitted, and the alarm light remains on, triggering an alarm. As the displacement scale 3 moves to the second concave protrusion 31, the first brass guide block 522 shifts away from the first brass guide block 522, and the alarm volume increases. As this continues, the alarm volume increases to its maximum value.

[0045] When manual maintenance is required, the switch on the alarm needs to be pressed to reset the alarm to zero.

[0046] As a further embodiment of the present invention, both the first flange 1 and the second flange 2 include a first hoop and a second hoop, and the inner walls of the first hoop and the second hoop are recessed structures, and an arc-shaped elastic element 100 is provided in the recessed structure. The arc apex of the arc-shaped elastic element 100 (elastic steel plate) is an arc-shaped part 101 that protrudes toward the hoop axis.

[0047] Furthermore, a rubber pad is provided on the outer wall of the arc-shaped part 101 facing the axis of the hoop.

[0048] Specifically, after the first flange 1 and the second flange 2 are clamped onto the heat pipe 10, the arc-shaped part 101 abuts against the heat pipe 10, thereby ensuring the firmness of the flange fixed to the heat pipe 10.

[0049] As another embodiment of the present invention, the arc-shaped elastic element 100 further includes, according to its structure, a wave-shaped elastic metal part 102 arranged symmetrically about the arc-shaped portion 101.

[0050] Specifically, in the embodiment, when the arc-shaped portion 101 abuts against the heat pipe 10, the end of the arc-shaped portion 101 abuts against the side wall of the recessed structure and then transmits force to both sides. At this time, the wave-shaped elastic metal part 102 provides the opposite force, thereby squeezing the end of the arc-shaped portion 101 and applying a squeezing force to the heat pipe 10, thereby ensuring the firmness of the flange fixed to the heat pipe 10.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
