Abstract
The utility model discloses an annunciator of a shearing pin of a water turbine. The annunciator of the shearing pin of the water turbine is composed of an inserted part (1), an exposed part (2) and an electric outgoing line (3), wherein the bottom surface of the exposed part (2) is a surface (2a) in contact with the shearing pin, and a magnetic anti-slipping piece (4) is fixedly arranged on the bottom of the exposed part (2). Due to the additional arrangement of the anti-slipping piece (4) made of a magnetic ring or a magnetic nail, the annunciator of the shearing pin and the shearing pin can be firmly fixed together through the anti-slipping piece (4), and the annunciator of the shearing pin is effectively prevented from slipping out of an installation hole of the shearing pin. Furthermore, due to the regular structure, the regular installation, and the attractive appearance of the anti-slipping piece (4), defects caused when an iron wire or adhesive tape is used for fixing the annunciator of the shearing pin in a traditional method can be well overcome.
Description
Technical field
The utility model belongs to the water turbine field, specifically, relates in particular to the break pin advertiser on the water turbine.
Background technique
At present, guide vanes of water turbine is closed protection and is generally adopted the break pin advertiser.As shown in Figure 1, 2, traditional break pin advertiser is made of insertion portion (1), exposed part (2) and electric lighting outlet (3), and wherein the bottom surface of exposed part (2) is and the break pin surface of contact.Described insertion portion (1) is multi-layer structure, its outer tube is made by plexiglass, in outer tube, be provided with electrical assembly, this electrical assembly links to each other with described electric lighting outlet (3), and, described insertion portion (1) inserts in the break pin mounting hole of steel during installation, and fits with the aperture of break pin surface of contact and this mounting hole.
When stator was stuck, break pin was cut off, and the break pin advertiser in the break pin mounting hole is also cut off simultaneously, gave the monitor staff thereby send alarm signal, and then realized reporting to the police.Because the influence of factors such as unit vibration, traditional break pin advertiser slides out in the mounting hole of break pin easily, and the monitor staff just can not judge accurately whether unit is fully closed like this, can not get reliable protection thereby cause stator to be closed.
In order to prevent that the landing of break pin advertiser from going out the mounting hole of break pin, the general iron wire that adopts fixes the break pin advertiser at present, perhaps inserts in the mounting hole of break pin after the insertion portion of break pin advertiser twines adhesive tape earlier again.After adopting the above-mentioned counter measure, go out the mounting hole of break pin though can effectively prevent the landing of break pin advertiser, the profile of iron wire or adhesive tape is irregular, will influence overall appearance like this.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of water turbine break pin advertiser, can not only avoid well that landing goes out in the mounting hole of break pin, and aesthetic is good.
The technical solution of the utility model is as follows: a kind of water turbine break pin advertiser, constituted by insertion portion (1), exposed part (2) and electric lighting outlet (3), and the bottom surface of exposed part (2) is and break pin surface of contact (2a), it is characterized in that: described exposed part (2) bottom is installed with the anti-sliding part (4) with magnetic.
The utility model sets firmly the anti-sliding part (4) with magnetic in described exposed part (2) bottom on the basis of conventional construction.Because break pin is steel structure, so when the insertion portion (1) of break pin advertiser inserts in the mounting hole of break pin, the anti-sliding part (4) that exposed part (2) bottom has magnetic can closely contact with the break pin of steel, so just the break pin advertiser can be installed in the mounting hole of break pin securely, and can prevent the break pin advertiser effectively because factor landings such as unit vibration go out the mounting hole of break pin.In addition, the profile of described anti-sliding part (4) and equal comparison rule is installed, aesthetic is good, so just can overcome tradition well and adopt iron wire or adhesive tape to fix the defective of break pin advertiser.
As a kind of embodiment of the present utility model, described anti-sliding part (4) is magnet ring, the shaft axis of this magnet ring overlaps with the shaft axis of insertion portion (1), outside thread on the magnet ring links to each other with the interior threaded hole of described exposed part (2) bottom, and the bottom surface of magnet ring is with described concordant with break pin surface of contact (2a).
As another embodiment of the present utility model, described anti-sliding part (4) is the magnetic nail, the shaft axis of this magnetic nail and the axis parallel of insertion portion (1), and the bottom of magnetic nail is with described concordant with break pin surface of contact (2a).
In the utility model, the number of described magnetic nail is 3 to 5, and these magnetic nails are contained in respectively in the corresponding axial mounting hole in exposed part (2) bottom.
As preferably, the number of described magnetic nail is 4, these 4 magnetic nails circumferentially evenly arranging along exposed part (2).
As optimization, the head of described magnetic nail down, afterbody is up.
Beneficial effect: the utility model has been set up the anti-sliding part of being made by magnet ring or magnetic nail etc. (4), so just can this break pin advertiser and break pin be fixed together securely by anti-sliding part (4), prevent that effectively the landing of this break pin advertiser from going out in the mounting hole of break pin, and the structure of anti-sliding part (4) and equal comparison rule, good-looking is installed so just can overcome tradition well and adopt iron wire or adhesive tape to fix the defective of break pin advertiser.
