Abstract
A wave dissipation block comprises a hollow structure 1 with a plurality of conical holes 6 in its outer surface which holes are in communication with the hollow interior for wave breaking and wave energy dissipation. The penetrating holes can be made in different size, different slope and different shape for multi-directional wave dissipation effect. The hollow interior space can be installed with some partition walls each with a plurality of penetrating holes. Furthermore, one or more stone inlets 7 can be made on the top of each block for placing stones in the hollow interior space in order to improve its stability and to provide further wave dissipation effect. The surface of each wave dissipation block can have tenons and mortises for interconnection of adjacent blocks. <IMAGE>
Description
SPECIFICATION
Wave dissipation device
The present invention relates to a hollow comb type wave dissipation block, particularly one with a plurality of penetrating holes on its surface and a hollow interior space for secondary wave breaking and wave energy dissipation.
Generally, the conventional wave dissipation block is of solid structure which provides good stability with its own weight, but, on the contrary, requires considerably high production cost. Though there are changes on the ridges over its surface, wave breaking and wave energy dissipation effects depend entirely on the porosity formed after placement of wave dissipation blocks. Because of consideration on stability and wave dissipation effects, porosity is greatly restricted, and thus, wave dissipation effect so attained is limited.
In view of the above defects, the present invention was created with a main objective of providing a hollow comb type wave dissipation block with low production cost and with a hollow interior space and penetrating holes on its surface to provide secondary wave dissipation effect. The present invention can have a stone inlet on the top for placing of stones into the hollow interior space to improve its stability and provide further wave breaking and wave energy dissipation effects with gaps among the stones where waves can pass through.
The present invention is a hollow and preferably closed structure with a plurality of conical penetrating holes on its surface to enable waves to pass into its hollow interior space for wave breaking and wave energy dissipation. The penetrating holes can have different sizes, different slopes and different shapes for multi-directional wave dissipation effect. The hollow interior space may be provided with partition walls, which may be equiangular, each with a plurality of penetrating holes to enable waves to flow through and cause additional wave breaking and wave energy dissipation. Furthermore, one or more inlets for stones can be made on the top of each wave dissipation block for placing stones in the hollow interior space in order to improve its stability and to provide further wave dissipation effect.The surface of the wave dissipation block may be provided with pairs of symetrical tenons and mortises to enable pairs of blocks to be connected together to give improved stability.

DETAILED DESCRIPTION OF THE FIRST EM
BODIMENT
Please refer to Figs. 1 and 2, the first embodiment of a hollow comb type wave dissipation block according to the present invention. The wave dissipation block (1) is a hollow cubical structure with a plurality of conical penetrating holes (6) on its surface for passing through of waves into the hollow interior space of the wave dissipation block (1). Since the penetrating holes (6) are of conical form, waves can enter the wave dissipation block (1) easily and thus a significant part of the wave energy can be dissipated. Since waves which have entered the wave dissipation block (1) can flow out through holes of smaller diameter, water flow can be slowed down, reflection and overlap of waves can be minimized.Furthermore, waver energy can be repeatedly dissipated in the hollow interior space, the hollow comb type wave dissipation block (1) according to the present invention has secondary wave breaking and energy dissipation effects. If the wave dissipation block (1) requires a large volume and its own weight has to be taken into consideration, it can have a stone inlet (7) on the top for placing stones into the hollow interior space of the wave dissipation block (1) in order to improve stability of the wave dissipation block (1) as well as to dissipate part of the wave energy while waves are passing through gaps among the stones therein for further wave dissipation effect.
DETAILED DESCRIPTION OF THE SECOND EM
BODIMENT
Please refer to Fig. 3, the second embodiment of a hollow comb type wave dissipation block according to the present invention. The wave dissipation block (2) is a hollow hexagonal block structure with a plurality of conical penetrating holes (6) on its surface. Its interior spaces has a plurality of equiangular partition walls (8) each with a plurality of penetrating holes (9) for flowing of waves among these partition walls (8) in order to break waves and dissipate wave energy to a further extent. Furthermore, each of the partitioned interior space can have a stone inlet (7) on the top for placing stones into it for the purpose of improving stability, breaking waves and dissipating wave energy.
DETAILED DESCRIPTION OF THE THIRD EM
BODIMENT
Please refer to Fig. 4, the third embodiment of a hollow comb type wave dissipation block according to the present invention. The wave dissipation block (3) is a symmetrical four-leg hollow structure with a plurality of conical penetrating holes (6) on its surface for passing through of waves into the hollow interior space for secondary wave breaking and energy dissipation.
Furthermore, the hollow comb type wave dissipation block according to the present invention can have its penetrating holes on its surface arranged in the form as the fourth embodiment shown in Fig. 5, and as the fifth embodiment shown in Fig. 6. Such penetrating holes are constructed in different size, different shape and different slope for multi-directional wave dissipation effects. Wave dissipation function of these two embodiments is illustrated in Fig. 7. When a wave A is approaching a wave dissipation block horizontally, the wave A reaches walls of these penetrating holes at different time for the penetrating holes are of different sizes, slope and shape. Therefore, the wall gives different wave dissipation effects so that the wave A are passing through the penetrating holes in different directions and a significant part of wave energy can be dissipated before secondary wave breaking and energy dissipation are proceeded within the hollow interior space.
Moreover, the hollow comb type wave dissipation block according to the present invention can have some pairs of symmetrical tenons (10) and mortises (11) for integration and improvement of stability in case a number of wave dissipation blocks are to be placed together.
