A triangular frame pressure block for navigation mark

Abstract

The invention discloses a triangular frame saddle weight for a navigation mark. The saddle weight is sunk in a water bottom to fix the navigation mark through dead weight, the condition in water is changed acutely, and the navigation mark is likely to shift and be lost. The triangular frame saddle weight for the navigation mark comprises three saddle weight outer plates, handles and three saddle weight inner plates. The three saddle weight outer plates are connected end to end to form a triangular outer frame, the upper and lower edges of the saddle weight outer plates are provided with saw teeth, the three top ends of the triangular outer frame are provided with the handles, the three saddle weight inner plates are connected end to end inside the triangular outer frame to form a triangular inner frame, and the top ends of the triangular inner frame are fixed to the middles of the inner sides of the saddle weight outer plates. When placed in the water bottom, the saddle weight is inserted into sediment due to the dead weight, four cavities are filled with the sediment, and the saddle weight is gradually sunk into the sediment to be fixed. The saddle weight is fixed with no dead weight, so that the dead weight is lower compared with general saddle weights, and operation is convenient when placement or overhaul is performed; relative to dead weight fixing, the saddle weight is sunk into sediment to be connected with a seabed into a whole, and the better fixing effect can be achieved.

Description

technical field [0001] The invention relates to a navigation mark, in particular to a weight block used for the navigation mark, and belongs to the technical field of mechanical manufacturing. Background technique [0002] Navigation mark is the abbreviation of navigation mark, which is used to indicate the direction and boundary of the channel, guide the navigation of ships, locate and mark obstacles, mark warnings, and provide safety information for various water activities. There are many classifications of navigation marks, including river crossing marks, coastal marks, guide marks, transitional guide marks, head and tail guide marks, side marks, left and right navigation marks, position indicating marks, flood marks and bridge and culvert marks. No matter what kind of navigation mark, its structure is roughly the same, consisting of the main body of the navigation mark on the water surface and the fixed weight block under the water surface. The weight block sinks to th...
