Self-protection pipeline for thermal power generating unit

Abstract

The application belongs to the technical field of thermal power generation, and particularly relates to a self-protection pipeline of a thermal power generating unit. The pipeline comprises a mounting cylinder and a pipeline body. The pipeline body is arranged in the mounting cylinder and is in sliding connection with the mounting cylinder. A protection assembly is arranged on the mounting cylinder. The protection assembly can open or close the outlet end of the pipeline body. The mounting cylinder is in sliding connection with the pipeline body. The protection assembly can be driven to open or close the outlet end of the pipeline body by sliding the mounting cylinder along the pipeline body. The protection assembly can be driven to move by sliding the mounting cylinder along the pipeline body, so as to open or close the outlet end of the pipeline body, avoid dust from blocking the pipeline, and realize self-protection of the pipeline. When the mounting cylinder slides, the torsional spring rotates to drive the cover plate to move along the outer sidewall of the pipeline body, so that the outlet end of the pipeline body is opened. When it is needed to close the outlet end of the pipeline body, the mounting cylinder is reversely slid, and the cover plate is restored to be perpendicular to the sidewall of the pipeline body under the action of the torsional spring.

Technical Field

[0001] This application belongs to the field of thermal power generation technology, and in particular relates to a self-protection pipeline for thermal power generating units. Background Technology

[0002] Thermal power generator sets use coal, oil, or combustible gases as fuel to heat water in a boiler, which then generates electricity by using pressurized steam to drive a turbine. The environment in which thermal power generator sets are located is often dusty, and some pipes are left open for extended periods after use, making it easy for dust to enter the pipes. Over time, the accumulation of dust can cause blockages in the pipes. Summary of the Invention

[0008] Optionally, a sliding groove is provided on the outer wall of the pipe body, and a slider is provided on the inner wall of the mounting cylinder. The slider is slidably connected to the sliding groove through a roller, and the sliding groove is used to limit the position of the mounting cylinder.

[0009] Optionally, the positioning element includes two slots arranged on the outer wall of the pipe body, the two slots being arranged radially along the pipe body, and a retractable locking block provided on the mounting cylinder, the retractable locking block engaging with the slots; when the outlet end of the pipe body is in the open state, the retractable locking block engaging with the slot near the inlet end of the pipe body; when the outlet end of the pipe body is in the closed state, the retractable locking block engaging with the slot on the side away from the inlet end of the pipe body.

[0010] Optionally, the mounting cylinder has a sliding cavity, and the retractable locking block includes a locking block that passes through the sliding cavity.

[0013] Compared with the prior art, this application has at least the following beneficial effects: This application allows the protective components to move by sliding the installation cylinder along the pipe body, thereby opening or closing the outlet end of the pipe body. When not in use, the outlet end of the pipe body can be closed to prevent dust from clogging the pipe, thus achieving self-protection of the pipe.

[0014] The mounting cylinder is connected to the cover plate via a torsion spring. When the mounting cylinder slides, the torsion spring rotates, causing the cover plate to move along the outer wall of the pipe body, thus opening the outlet end of the pipe body. When it is necessary to close the outlet end of the pipe body, the mounting cylinder slides in the opposite direction, and the cover plate returns to being perpendicular to the side wall of the pipe body under the action of the torsion spring.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0019] Example 1

[0020] like Figures 1-4 As shown, a self-protection pipeline for a thermal power generating unit includes an installation cylinder 1 and a pipeline body 2. The pipeline body 2 is arranged inside the installation cylinder 1 and is slidably connected to the installation cylinder 1. A protective component is provided on the installation cylinder 1. The protective component can open or close the outlet end of the pipeline body 2. The installation cylinder 1 is slidably connected to the pipeline body 2. By sliding the installation cylinder 1 along the pipeline body 2, the protective component can be driven to open or close the outlet end of the pipeline body 2.

[0021] The mounting cylinder 1 slides along the pipe body 2, which can move the protective component, thereby opening or closing the outlet end of the pipe body 2. When not in use, the outlet end of the pipe body 2 can be closed to prevent dust from clogging the pipe and achieve self-protection of the pipe.

[0026] When the mounting cylinder 1 slides away from the outlet end of the pipe body 2, the torsion spring is twisted, causing the cover plate (semi-circular protective plate 5) to move along the outer side wall of the pipe body 2, and the outlet end of the pipe body 2 can be opened; when it is necessary to close the outlet end of the pipe body 2, the mounting cylinder 1 is slid in the opposite direction, the torsion spring is restored and the cover plate is driven back to be perpendicular to the side wall of the pipe body 2, and the pipe can be closed.

[0027] A positioning element is provided between the mounting cylinder 1 and the pipe body 2. The positioning element is used to fix the mounting cylinder 1 and the pipe body 2 relative to each other when the outlet end of the pipe body 2 is in an open or closed state.

A retractable locking block 8 is provided on the mounting cylinder 1, engaging with the slots 7. When the outlet end of the pipe body 2 is open, the retractable locking block 8 engages with the slot 7 near the inlet end of the pipe body 2; when the outlet end of the pipe body 2 is closed, the retractable locking block 8 engages with the slot 7 on the side furthest from the inlet end of the pipe body 2. The positioning element ensures that the mounting cylinder 1 and the pipe body 2 are relatively fixed when the outlet end of the pipe body 2 is open or closed.

[0029] The mounting cylinder 1 has a sliding cavity 82. The retractable locking block 8 includes a locking block 81, which is inserted into the sliding cavity 82.

Both the spring 84 and the limiting plate 83 are set in the sliding cavity 82. The spring 84 is arranged between the sliding cavity 82 and the limiting plate 83 on the side of the sliding cavity 82 near the pull ring 6.
