Detailed Description
As shown in fig. 1 to 5, a hood guard for a hydroelectric generating set comprises a guard body, wherein the guard body is a frame structure formed by splicing a plurality of upright posts 1 and cross rods 5; the upright stanchion 1 is connected with the cross rod 5 through a docking mechanism; the protective guard body is in contact fit with the upper surface of the nose cover 9 through a fixing mechanism.
Preferably, the docking mechanism comprises a plurality of engaging lugs 2 connected to the outer surface of the upright 1, and the engaging lugs 2 are cylindrical structures with open upper surfaces.
Preferably, the two ends of the cross rod 5 are connected with bent connecting rods 6, and the connecting rods 6 are in inserted connection with the connecting lugs 2.
Preferably, the connecting lug 2 and the connecting rod 6 are provided with through jacks on the surfaces, and the jacks are internally provided with bolts for fixation.
Preferably, the fixing means comprise a fixing plate 3 attached to the outer surface of the upright 1, the fixing plate 3 being axially perpendicular to the upright 1.
Preferably, the part between the end of the upright 1 and the fixing plate 3 is an overlap section 11; the lap section 11 is in contact fit with the side surface of the nose cover 9.
Preferably, the surface of the fixing plate 3 is provided with fixing holes 4 matched with bolt holes 8 on the surface of a nose cover 9.
The work principle of the hood protective guard of the hydroelectric generating set is as follows:
when the device is used, the connecting rod 6 at the end part of the cross rod 5 is directly inserted into the connecting lug 2 of the vertical rod 1 to realize the connection of the vertical rod 1 and the cross rod 5, the vertical rod 1 and the cross rod 5 are connected into a stable closed whole, and are lapped at the edge above the circular head cover 9 through the fixing plate 3 to form a stable structure, and the stable protection is formed because the connecting rod cannot move in all directions; if necessary, partial original hood 9 cover plate bolt holes 8 can be removed, the left screw holes are utilized to be overlapped and butted with the fixing holes 4, fixing bolts 10 are installed, the fixing plate 3 is fixed on the hood 9, and then the air supply valve 7 and the like are overhauled.
