Problems solved by technology

[0003] However, this type of anti-wave revetment also has defects and deficiencies: the design of concrete revetment only pays attention to the strength and durability of the structure, without considering its impact on the ecological environment
However, this kind of ecological floating bed fluctuates with the fluctuation of the water surface, and does not have the ability to dissipate waves and protect the bank slope

Embodiment 1

[0030] The present invention is a semi-submersible perforated plate plant wave dissipation device, the specific structure is as follows Figure 1 ~ Figure 4 As shown, it includes a porous plate 1 , aquatic plants 2 , a buoy 3 and a positioning unit. The positioning unit includes an anchor chain 5 and a positioning pile 6 , and is connected to the buoy 3 through a hanging ring 4 .

[0031] Perforated plate 1 is the bigger ABS plastic plate of rigidity, long 100cm, wide 75cm, evenly offers the through hole 7 of interval 12cm on the plate, is used as planting hole and air hole of plant, and aperture is 20mm. Aquatic plants 2 are selected to grow vigorously and have a suitable height, and they are planted in the through holes 7 on the perforated plate 1 at intervals of 24 cm in the length and width directions, and the corresponding planting density is about 18 plants / m 2 .

[0032] The buoy 3 is made of PVC material with a length of 75 cm and is installed on the two short sides of...

Embodiment 2

[0036] A plurality of wave dissipation components are connected end to end through hanging rings and anchor chains to form a chain wave dissipation device. The anchor chains 5 on the wave dissipation components at both ends of the head and tail are respectively fixed on the bottom of the water through positioning piles 6, and the rest of the wave dissipation components are connected with the Example 1 is the same.

Abstract

The invention relates to a semi-submersible type perforated plate plant wave-breaking device which is used for breaking waves and purifying water of inland waters. The device comprises at least one wave breaking component. Each wave breaking component comprises a perforated plate, float bowls, positioning units and aquatic plants arranged on the perforated plate. The float bowls are fixedly arranged on the outer sides of the perforated plates and fixed to the water bottom through the positioning units. When waves of the inland waters are transmitted to the semi-submersible type perforated plate plant wave-breaking device, the waves slow down and are broken under the disturbance function of the perforated plates and the aquatic plants, a great amount of energy carried by the waves is consumed, the waves on the upper surfaces and the lower surfaces of the perforated plates are different in speed, waves passing the upper sides and the lower sides of the perforated plates impact on one another, wave energy is further consumed, and thus the wave breaking purpose is achieved. Compared with the prior art, the semi-submersible type perforated plate plant wave-breaking device has the beneficial effects of being simple in structure, low in cost, convenient to mount, good in applicability, modular in mounting, flexible in function switching and the like.

Description

technical field [0001] The invention relates to a wave-eliminating device, in particular to a semi-submersible wave-eliminating device for plants with porous plates. Background technique [0002] For a long time, waves have brought many negative effects on human engineering activities and civilization development. Under the erosion of waves, natural bank slopes and embankment structures will be washed, eroded, transported and finally destroyed, endangering the safety of the project. In inland waters such as lakes and reservoirs, the energy and destructive power carried by waves are far less than those in offshore areas, but the damage they cause to shore slope engineering cannot be underestimated. According to the flood reports in 1996 and 1998, among the engineering accidents in 241 large reservoirs in my country, there were nearly 200 damages to bank slopes and wharf fronts, of which 126 were caused by wind and waves, accounting for 64% of the total. Therefore, while uti...
