Description
Technical field
This utility model relates to a kind of probe mounting assembly, particularly relates to a kind of PMU rotor probe mounting assembly.
Background technology
In power plant, PMU relates to net equipment as one, has played very important work in scheduling with the contacting of power plant
With.PMU rotor probe is as the sampling instrument of PMU system, and it is arranged on Jiu Wachu, with speed measuring fluted disc to keep close away from
From.By the rotating speed with speed measuring fluted disc conjunction measuring axle, then by cable, rotor pulse is sent in PMU device.Rotor
Probe the most correctly installs the correctness of the data acquisition directly influencing PMU system.
The installation of power plant's PMU rotor probe at present is mainly fixed by welding on metal rack.And be welded and fixed
The shortcoming that mode is primarily present:
1, probe often to be dismantled and to install, and uses welding to carry out dismantling extremely bothering, adds regular maintenance
Workload；
2, probe is a precision instrument, and probe can be made in welding process to bear high temperature, and therefore having when welded and installed can
Probe can be caused damage, high temperature also can affect the service life of probe simultaneously, improves rate of breakdown；
The distance of probe with speed measuring fluted disc is adjusted when 3, installing, use welding to be inconvenient to be adjusted, it is impossible to
Accurately probe and the distance of rotor, affect the accuracy of PMU information gathering.
Utility model content
The purpose of this utility model is to provide a kind of PMU rotor probe mounting assembly, makes the removable company of rotor probe
Connect thereon, it is simple to change, regulate while can also prevent probe from dropping.
The utility model discloses a kind of PMU rotor probe mounting assembly, this mounting assembly includes support and removable
Unload the locking member being connected on support, pop one's head in and be removably connected on support complete to measure by locking member.
As preferably, described locking member includes elastic thread pipe and two nuts being attached to, elastic thread pipe
Internal diameter be matched with the external diameter of probe, probe is positioned at elastic thread pipe, and two nuts are respectively used to regulate probe positions and lock
Tightening position.
As preferably, described elastic thread tube wall is provided with an elongated axially open.
As preferably, the width of described axially open is less than 1/4th of described elastic thread pipe girth.
As preferably, the tube wall of described elastic thread pipe bottom is provided with some axially opens.
As preferably, described elastic thread Guan Ziqi length direction center is evenly equipped with three to the bottom tube wall of lower surface
Axially open.
As preferably, described support is inverted L-type, and its traversing section is provided with the installation for connecting described locking member
Hole, the aperture of installing hole is between the external diameter and the external diameter of described nut of described elastic thread pipe.
As preferably, the described nut for regulating probe positions is positioned at the upside of described support traversing section, is used for locking
The nut of location is positioned at the downside of support traversing section.
When this utility model uses, after fixing mounting assembly, it is removably connected to probe on support to survey
Amount, when tip damage or when needing to carry out altitude mixture control, only need to can be replaced and regulate by locking member.Improve more
The convenience changed decreases the workload of regular maintenance simultaneously, also allows for the regulation of probe positions, improves the accuracy of detection.
Meanwhile, for the ease of realizing the fine setting of probe positions, locking member is designed as elastic thread pipe and the spiral shell matched
Mother, the internal diameter of corrugated tubing is matched with the external diameter of probe, and the external diameter of corrugated tubing is less than the aperture of described installing hole, and the external diameter of nut is big
In installing hole aperture, it is interior by nut check that probe stretches into corrugated tubing, and nut has two, is respectively placed in the upper and lower of support traversing section
Both sides, upside be adjusting nut, downside be locking nut.
Accompanying drawing explanation
Fig. 1 is the schematic front view of this utility model preferred embodiment one.
Fig. 2 is the cross-sectional schematic in Fig. 1 at A.
Fig. 3 is the schematic front view of this utility model preferred embodiment two.
Diagram sequence number:
1 support, 2 elastic thread pipe I, 3 probes, 4 adjusting nuts, 5 locking nuts, 11 traversing sections,
12 vertical sections, 2A elastic thread pipe II.
Detailed description of the invention
Preferred embodiment one, as shown in Figure 1 and Figure 2, this PMU rotor probe mounting assembly disclosed in the present embodiment
Including support 1 and elastic thread pipe I 2, probe 3 is removably connected on support complete to measure by elastic thread pipe I.Wherein
Support 1 includes traversing section 11 and vertical section 12 for inverted L-type, and its traversing section 11 is provided with the peace for connecting locking member 2
Dress hole.Elastic thread pipe I 2 is evenly equipped with three openings, bullet on the bottom tube wall of its length direction center to lower surface vertically
Property corrugated tubing I 2 on be cased with the adjusting nut 4, the locking nut 5 that match, the internal diameter of elastic thread pipe I 2 is matched with outside probe 3
Footpath, the external diameter of elastic thread pipe I 2 is less than the aperture of installing hole, and the external diameter of adjusting nut 4 and locking nut 5 is all higher than installing hole
Aperture, probe 3 is locked by locking nut 5 in stretching into elastic thread pipe I 2, by the position of adjusting nut 4 fine setting probe 3.
When the present embodiment uses, after fixing support, probe is passed in elastic thread pipe I, then by locking nut
Screw on elastic thread pipe I, then elastic thread pipe I through installing hole and is locked by locking nut；Need
When the position popped one's head in is adjusted, rotate adjusting nut.Visible, improve replacing just by the use of the present embodiment
Victory, decrease the workload of regular maintenance, also allow for the regulation of probe positions, improve the accuracy of detection, simultaneously can also
Prevent probe from dropping.
Preferred embodiment two, as in figure 2 it is shown, the difference of the present embodiment and preferred embodiment one is: in this mounting assembly
Elastic thread pipe II 2A tube wall on be provided with an elongated opening vertically, and the width of opening is less than elastic thread pipe II
/ 4th of 2A girth.
