Description

Technical Field

[0001] This utility model relates to the field of engineering pipeline technology, specifically to a rotary compensator rotation angle measuring device. Background Technology

[0002] Rotary compensators for steam pipelines are frequently used in thermal engineering construction. Because the upper and lower parts of the compensator have relative angular displacement, it is difficult to measure their rotation angle, making it impossible to intuitively understand the pipeline's operational health. In other words, it is impossible to accurately know the current rotation angle of the compensator, or whether it has reached its limit value. Exceeding the limit value may lead to pipeline damage. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a rotary compensator rotation angle measuring device. By incorporating a rack, gear, and rotary encoder, it measures the distance the gear moves during the rotation of the rotary compensator, thereby calculating the arc length. The measured arc length is then converted to the pipe diameter to obtain the rotation angle of the rotary compensator, thus improving measurement accuracy. [The last sentence appears to be incomplete and possibly refers to the health status of a device.]

[0004] The technical solution provided by this utility model is as follows:

[0005] A rotary compensator rotation angle measuring device includes a rotary compensator, a rack is fixedly connected to the lower flange of the rotary compensator, a gear is meshed with the rack, a rotary encoder is mounted on the gear, and the rotary encoder is connected to a power source via a connecting wire.

[0006] Furthermore, the rack is welded to the lower flange of the rotary compensator.

[0007] Furthermore, the rack is positioned above the gear.

[0008] Furthermore, the rack is configured in an arc shape.

[0009] Furthermore, both the connecting wire and the power supply are located on the lower tube surface of the rotary compensator.

[0010] Furthermore, the output shaft of the rotary encoder is coaxially arranged with the gear.

[0011] The beneficial effects of this utility model are:

[0012] This utility model has a simple structure. By setting up an arc-shaped rack, gear, and rotary encoder, it measures the distance the gear moves when the rotary compensator rotates, and then calculates the arc length. Based on the arc length and pipe diameter, the rotation angle of the rotary compensator is obtained, thereby understanding the health status of the pipeline operation. Attached Figure Description

[0022] Example

[0023] like Figures 1 to 6 As shown, a rotary compensator 1 rotation angle measuring device includes a rotary compensator 1, a rack 2 is fixedly connected to the lower flange 7 of the rotary compensator 1, a gear 3 is meshed with the rack 2, a rotary encoder 4 is provided on the gear 3, and the rotary encoder 4 is connected to a power supply 6 through a connecting wire 5, wherein the power supply 6 is used to supply power to the rotary encoder 4.

[0024] As a further technical solution in this embodiment, the rack 2 is welded to the lower flange 7 of the rotary compensator 1 for easy fixation.

[0025] As a further technical solution in this embodiment, the rack 2 is disposed above the gear 3.

[0026] As a further technical solution in this embodiment, the rack 2 is arranged in an arc shape, and the arc shape is adapted to the lower flange 7 of the rotary compensator 1, and fits it more closely.

[0027] As a further technical solution in this embodiment, both the connecting wire 5 and the power supply 6 are located on the lower tube surface of the rotary compensator 1 to avoid tangling.

[0028] As a further technical solution in this embodiment, the output shaft of the rotary encoder 4 is coaxially arranged with the gear 3, which facilitates the measurement of the distance moved by the gear 3.

[0029] The working principle of this utility model:

[0030] When the pipeline is in a cold state, the rotary compensator 1 does not rotate; when the pipeline is in a hot state, the pipeline expands due to heat, which drives the rotary compensator 1 to rotate. When the lower pipe of the rotary compensator 1 rotates, it drives the rack 2 to rotate. The gear 3, which meshes with the rack 2, rotates along the rack 2. The rotary encoder 4, which is connected to the gear 3, measures the angular displacement of its output shaft, and then measures the distance that the gear 3 moves, which is the arc length, and thus the rotation angle of the rotary compensator 1 is obtained.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the principles and essence of the present utility model should fall within the protection scope defined by the claims of the present utility model.
