[0002] During the operation of the power plant boiler, when the inclination angle of the hanger is too large, the force of the support point will be redistributed according to its inclination angle, and the abnormal state of a single support point will change the load distribution of the support system, affect the thermal expansion and contraction of the pipeline, and cause the pipeline to vibrate, which has a great impact on the safe, economical and environmentally friendly operation of the boiler. Therefore, it is necessary to ensure that the inclination angle of the support hanger is within the range allowed by the standard.

[0003] At present, most of the angle measurement devices for hanger rods use sensors installed on the hanger rods for detection in order to measure specific tilt data. However, there are hundreds of hanger rods for pipelines in thermal power plants, and most of them are difficult to install or require scaffolding for installation. Therefore, the method of installing sensors on each hanger rod to measure the tilt data requires a large amount of construction, is time-consuming, inconvenient to install, and has high labor and equipment costs.

[0004] Therefore, there is an urgent need to propose a corresponding solution to the problem of how to accurately and efficiently detect whether the hundreds of support and hanger rods in thermal power plants are tilted beyond the standard. Utility Model Content

[0007] In some embodiments, the lens barrel includes a front lens barrel and a rear lens barrel, the front lens barrel is rotatably connected to the rear lens barrel via a bearing, and the lens is detachably connected to the front lens barrel.

[0009] In some embodiments, the counterweight assembly is mounted at one end of the front lens barrel close to the bearing, and the lens is threadedly connected to one end of the front lens barrel away from the rear lens barrel. In the connected state, the connection point where the counterweight assembly is connected to the front lens barrel is located in the same plane as the auxiliary line.

[0010] In some embodiments, the counterweight assembly includes a counterweight block and a receiving slot formed therein for receiving the counterweight blocks of different weights.

[0011] In some embodiments, the accommodating groove includes two positioning clamping plates connected to the lens barrel at a relative interval, and the outer wall of at least one of the positioning clamping plates is connected to the lens barrel through a spring.

It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] In order to overcome the problem that the existing technology of installing sensors on hundreds of support and hanger rods to measure the inclination data requires large construction volume, takes a long time, is inconvenient to install, and has high personnel and equipment costs, and is not convenient for efficiently detecting whether the support and hanger rods are tilted beyond the standard.

[0038] like Figures 1 to 5 As shown, the utility model provides a tilt detection device, comprising a lens barrel 1, a lens 2 connected to the end of the lens barrel 1, a counterweight assembly 3 installed on the lens barrel 1, and an illumination assembly 4 installed in the lens barrel 1 and irradiating light toward the lens 2. The lens 2 is provided with a plurality of engraved lines 5 passing through the center of a circle, the engraved lines 5 include auxiliary lines 51, and the connection point where the counterweight assembly 3 is connected to the lens barrel 1 is located in the same plane as the auxiliary lines 51, so that the position of the lens barrel 1 can be corrected with the counterweight assembly 3 as a reference, so that the auxiliary lines 51 extend in the vertical direction.

[0039] Specifically, the connection point where the counterweight assembly 3 is connected to the lens barrel 1 can be located in the same plane as the auxiliary line 51, that is, the counterweight assembly 3 and the auxiliary line 51 are located on the vertical section of the lens barrel 1, and the gravity characteristics of the counterweight assembly 3 are used to correct the position of the lens barrel 1, so that the auxiliary line 51 on the lens 2 can extend in the vertical direction to achieve vertical correction, and the lighting assembly 4 is used to irradiate light onto the lens 2. Due to the principle of light reflection, the brightness of the position of the engraved line 5 is significantly higher than that of other parts of the lens 2, so that it can be used as an angle reference line, and then by observing whether the inclination angle of the support bracket hanger rod is within the engraved line range, it can be judged whether the inclination angle of the support bracket hanger rod exceeds the standard. This not only facilitates the observation of hundreds of support bracket hanger rods in thermal power plants, effectively improves the detection efficiency and saves time, but also has a simple structure and is easy to install.

[0040] Wherein, in some embodiments, reference Figure 1 and Figure 2 As shown, the lens barrel 1 comprises a front lens barrel 11 and a rear lens barrel 12 , the front lens barrel 11 is rotatably connected to the rear lens barrel 12 via a bearing 6 , and the lens 2 is detachably connected to the front lens barrel 11 .

[0041] Specifically, Figure 1 and Figure 2 As shown, the front lens barrel 11 and the rear lens barrel 12 can be rotatably connected by a bearing 6. The bearing 6 is highly flexible and cooperates with the counterweight assembly 3 installed on the lens barrel 1. The front lens barrel 11 connected to the lens 2 can be flexibly rotated by using gravity, so as to correct the position of the auxiliary line 51, so that the auxiliary line 51 on the lens 2 extends in the vertical direction to achieve vertical correction, which is convenient for observing whether the boom is tilted.

[0042] Furthermore, if Figure 2 As shown, the cross section of the front lens barrel 11 is larger than the cross section of the rear lens barrel 12, and the front lens barrel 11 is sleeved on the rear lens barrel 12. It can be understood that the front lens barrel 11 is sleeved outside the rear lens barrel 12 so that the front lens barrel 11 can be flexibly rotated to achieve vertical correction.

[0043] And, if Figure 1 and Figure 3 As shown, the counterweight assembly 3 is installed at one end of the front lens barrel 11 close to the bearing 6, and the lens 2 is connected to the end of the front lens barrel 11 away from the rear lens barrel 12 through a thread. In the connected state, the connection point of the counterweight assembly 3 connected to the front lens barrel 11 is located in the same plane as the auxiliary line 51.

[0044] Specifically, Figure 3As shown, the weight assembly 3 is installed at one end of the front lens barrel 11 close to the bearing 6, and is arranged so that the gravity of the weight assembly 3 can pull the front lens barrel 11 to rotate relative to the rear lens barrel 12 to correct the orientation of the auxiliary line 51, and the connection point where the weight assembly 3 is connected to the front lens barrel 11 is located in the same plane as the auxiliary line 51, so that after the front lens barrel 11 is corrected, the auxiliary line 51 of the lens 2 can extend in the vertical direction, perpendicular to the ground, to achieve vertical correction. In addition, the lens 2 can be connected to the front lens barrel 11 by a thread. When the auxiliary line 51 on the lens 2 extends in the vertical direction and is perpendicular to the ground, it means that the vertical correction is accurate; if the auxiliary line 51 is tilted, it can be adjusted by rotating the screw until the auxiliary line 51 of the lens 2 extends in the vertical direction.

[0045] Wherein, in some embodiments, Figure 5 As shown, the counterweight assembly 3 includes a counterweight block 31 and a receiving groove formed therein for receiving counterweight blocks 31 of different weights. Counterweight blocks 31 of different weights can be added or removed according to the different flexibility of the bearing 6 to ensure that the vertical line of the auxiliary line 51 is perpendicular to the ground to achieve vertical correction.

[0046] Furthermore, combined with Figure 5 As shown, the receiving groove includes two positioning clamps 32 connected to the lens barrel 1 at a distance from each other, and the outer wall of at least one positioning clamp 32 is connected to the lens barrel 1 through a spring 33. It can be understood that since it is necessary to add or remove counterweights 31 of different weights, under the action of the tension of the spring 33, it can be ensured that the counterweights 31 of different weights can always be clamped in the receiving groove to prevent the counterweights 31 from leaking out.

[0047] In some embodiments, in combination Figure 1 and Figure 4 As shown, the engraved line 5 also includes a plurality of reference lines 52 of different angles arranged to cross each other with the auxiliary line 51 as the axis of symmetry. It can be understood that, with the reference lines 52 of different angles as the observation range, when the inclination of the support and hanger rod is within the range of the reference line 52, it is up to standard; if the support and hanger rod is not within the range of the reference line 52, it is not up to standard.

[0048] Specifically, such a setting facilitates the operator to observe a large number of support and hanger rods. The angle division of the reference line 52 can be divided according to the actual situation of the support and hanger of the thermal power plant. In addition, the angle of the reference line 52 should not be divided too much to avoid affecting the observation. According to the needs, the angles of the closer divisions can be set on different lenses 2. According to the actual situation, different lenses 2 can be replaced for easy observation.

[0049] In some embodiments, the lens 2 can be made of high-transmittance PVC material, so that when the light is irradiated to the engraved line 5 on the lens 2, obvious reflection can occur, so that the brightness at the engraved line 5 can be significantly higher than other parts of the lens 2, thereby facilitating the observation of the inclination degree of the support bracket suspension rod.

[0050] In some embodiments, in combination Figure 3 As shown, the lighting assembly 4 is detachably installed in the front lens barrel 11 , and the lighting assembly 4 includes an LED lamp that irradiates light toward the lens 2 .

[0051] Specifically, combined Figure 3 As shown, the lighting assembly 4 can be installed at one end of the front lens barrel 11 near the lens 2 and at the same horizontal line as the counterweight assembly 3 to avoid uneven gravity on the front lens barrel 11 and the inability to rotate for correction. In addition, the LED light can shine light toward the lens 2, so that the brightness of the engraved line 5 on the lens 2 can be significantly higher than other parts through the radiation of light, which can be used as a basis for judging whether the support bracket suspension rod is tilted.

[0052] In some embodiments, the lens barrel 1 can be made of stainless steel. This arrangement prevents the lens barrel 1 from being easily damaged, and the lens barrel 1 is light in texture, making it convenient for a worker to hold the lens barrel 1 and observe the inclination of the support and hanger rod.
