Description

Technical Field

[0001] The invention relates to a rotation speed sensor for a steam turbine, in particular to a rotation speed sensor protection structure. Background Art

[0002] The conventional speed sensor terminal is not protected by a shell and is exposed outside. Therefore, it is easy to step on or bump into the terminal by mistake during the installation of the unit, resulting in damage to the speed sensor and seriously shortening the service life of the sensor. Therefore, it is necessary to design a speed sensor protection structure to protect the exposed terminal of the speed sensor. Summary of the invention

[0003] The present invention proposes a novel rotation speed sensor protection structure, which protects the exposed wiring head position of the rotation speed sensor through a simple combination of parts, greatly improves the use environment of the sensor, avoids damage to the sensor during the external construction of the unit, and increases the actual service life of the sensor.

[0004] To achieve the above purpose, the technical solution of the present invention is: a speed sensor protection structure, including a protective cover, a cover plate, and a wire outlet cover, the protective cover is fixedly connected to the speed sensor body; the cover plate is fixedly connected to the protective cover; and a wire outlet cover is provided on the side of the protective cover as a sensor wiring channel.

[0005] Furthermore, a threaded structure is provided on the outer circumference side of the speed sensor, and the protective cover is fixed to the speed sensor through the thread.

[0006] Furthermore, the rotation speed sensor is installed on the unit body through threads.

[0007] Furthermore, an adjusting gasket is provided at the connection between the speed sensor and the upper end surface of the unit body.

[0008] Furthermore, the cover plate and the outlet sleeve are fixedly connected to the protective sleeve via threads respectively.

[0009] Furthermore, the external wiring enters the protective cover through the outlet cover and is connected to the speed sensor body.

[0010] The beneficial effects of the present invention are:

[0011] The rotation speed sensor protection structure of the present invention is relatively simple in composition and easy to implement. It can adjust the local interface according to the actual situation of the sensor, provide protection for various sensors, effectively avoid unnecessary accidental damage on site, and increase the service life of the sensor. The rotation speed sensor protection structure of the present invention avoids accidental damage to the sensor caused by trampling and bumping on the construction site, realizes effective protection of the sensor, and makes the sensor have a longer service life on site.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a rotation speed sensor protection structure of the present invention mainly comprises 7 parts: a cover plate 1, a protective cover 2, a lead cover 3, an adjustment gasket 4, a unit body 5, a rotation speed sensor 6, and a detected shaft surface 7. The rotation speed sensor 6 is installed on the unit body 5 by threads, and the gap between the rotation speed sensor 6 and the detected shaft surface 7 is adjusted to within a qualified range by adjusting the gasket 4, and then fixed.

[0016] In order to facilitate the installation of the protection structure, a threaded structure is provided on the outer circumference of the rotation speed sensor 6, and the protection cover 2 and the rotation speed sensor 6 are fixed by the thread.

[0017] After the adjustment gasket 4, the speed sensor 6 and the protective cover 2 are in place, the external wiring is connected to the main body of the speed sensor 6 through the opening on the protective cover 2.

[0018] The cover plate 1 and the outlet sleeve 3 are fixed to the protective sleeve 2 by screwing. The cover plate is designed to facilitate the disassembly and assembly of the wiring head, and finally realizes the overall sealing of the protective structure.

[0019] The outlet sleeve 3 is the channel for the sensor wiring.
