Detailed Description
The invention is described in further detail below with reference to the drawings and specific examples.
Fig. 1 to 3 show an embodiment of the device for beach maintenance, wave dissipation and floater collection according to the present invention, which includes a wave dissipation block 1, a collection net cage 2 disposed on the wave dissipation block 1, and an anchor chain 3 for connecting the wave dissipation block 1, wherein the wave dissipation block 1 is provided with a channel 11 from the wave facing surface to the back wave surface, the size of the channel 11 is gradually reduced, and the wave facing surface of the collection net cage 2 is provided with a one-way baffle 21 for preventing floaters from flowing out. The wave dissipation block 1 is preferably in a frustum pyramid shape, is good in wave dissipation effect, easy to manufacture and mold, and convenient to arrange the collecting net cage 2 at the top, is preferably molded by concrete pouring, is low in cost, heavy in mass, good in corrosion resistance, resistant to seawater impact, and long in service life; the channel 11 is preferably a circular cross-section channel, and has a better beach-nourishing and siltation-promoting effect.
According to the device for beach maintenance, wave dissipation and floater collection, the wave dissipation block 1 is fixed on a beach near a shore area through the anchor chain 3, when wave impact occurs, the wave dissipation block 1 can reduce the energy of the wave, the wave dissipation purpose is achieved, the beach behind the wave dissipation block 1 is protected, the coastal erosion is reduced, and meanwhile, when silt carried in the wave impacts the wave dissipation block 1, the silt reaches the rear part of the wave dissipation block 1 through the channel 11 in the wave dissipation block 1, and because the size of the wave-facing surface of the channel 11 is large and the size of the wave-facing surface is small, the backflow speed of seawater can be reduced, the silt is deposited near the wave-facing surface, and the effects of beach maintenance and silt promotion are achieved; when floaters impact the collecting net cage 2 along with the waves, the one-way baffle 21 on the wave-facing surface of the collecting net cage 2 is flushed away, the floaters automatically enter the collecting net cage 2 to be collected, the one-way baffle 21 can prevent the floaters from flowing out of the collecting net cage 2 along with the backflow of the seawater, the structure is simple and reliable, and the efficiency of collecting the floaters is improved.
Further, in this embodiment, the device for beach maintenance, wave dissipation and floater collection further comprises a floating block 5, and the collecting net cage 2 is of a telescopic structure and is connected with the floating block 5. The floating block 5 is preferably a high polymer foam plate, has light weight, can provide sufficient buoyancy, and has low cost, good corrosion resistance and long service life. When the tide rises, the floating block 5 at the top of the device rises along with the rise of the water level, and then the collecting net cage 2 is driven to extend, so that the capacity of the collecting net cage 2 is increased, and the requirement of collecting more floaters is met. When the tide is drawn back, the floating block 5 descends, and the collecting net cage 2 is contracted and reset under the action of the gravity of the collecting net cage, so that the structure is simple and the use is convenient.
