Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 14, a floating breakwater according to an embodiment of the present invention includes: a floating body 111, at least one bank 112 fixed to the top of the floating body 111; the breakwater 112 is located between the wave-facing surface and the back wave-facing surface of the floating body 111, the distance between the wave-facing surface and the back wave-facing surface of the breakwater 112 is smaller than the distance between the wave-facing surface and the back wave-facing surface of the floating body 111, and a first preset distance is reserved between the wave-facing surface of the breakwater 112 close to the wave-facing surface of the floating body 111 and the wave-facing surface of the floating body 111.
It can be understood that, the specific value of the first preset distance is set according to actual needs, and this embodiment does not limit this. In fig. 6 and 11, the curves represent waves and the arrow lines represent wave directions. The breakwater 112 near the wave-facing side of the floating body 111 may be referred to as a wave-facing breakwater, i.e., a first predetermined distance is provided between the wave-facing side of the wave-facing breakwater and the wave-facing side of the floating body 111.
In the floating breakwater unit provided in the above embodiment, the breakwater 112 is disposed at the top of the floating body 111, the breakwater 112 is located between the wave-facing surface and the back wave-facing surface of the floating body 111, and the distance between the wave-facing surface and the back wave-facing surface of the breakwater 112 is smaller than the distance between the wave-facing surface and the back wave-facing surface of the floating body 111, so that compared with the existing unit, the material consumption is effectively reduced, and the overall weight, the manufacturing cost and the maintenance cost are reduced; moreover, a first preset distance is reserved between the wave-facing surface of the breakwater 112 close to the wave-facing surface of the floating body 111 and the wave-facing surface of the floating body 111, so that the wave-absorbing effect is effectively improved. Therefore, the floating breakwater component unit provided by the utility model improves the wave absorbing effect and reduces the cost.
In order to simplify installation and facilitate manufacture, the floating body 111 and the bank 112 may be selected to have an integrated structure. Of course, the floating body 111 and the bank 112 may be a separate structure, and are not limited to the above embodiment.
In the above-mentioned floating breakwater unit, the number of the breakwaters 112 may be one or more than two. In practical applications, the number and size of the floating body bodies 111 and the number and size of the breakwaters 112 may be adjusted according to wave conditions, thereby adjusting the wave-damping effect to prevent waves from crossing the overall structure.
If there are at least two breakwaters 112, in order to improve the wave-breaking effect, at least two breakwaters 112 may be selected, and the distribution direction of any two breakwaters 112 is the same as the distribution direction of the head-on wave surface and the back-off wave surface in each breakwater 112, and a gap is provided between any two breakwaters 112. In this way, each floating breakwater unit can achieve at least two breakwaters.
Of course, adjacent two banks 112 may be selected to be in contact or connected, and are not limited to the above-described embodiment.
In the above-described floating breakwater unit, the position of the dam 112 on the floating body 111 is selected according to actual needs. Specifically, a second preset distance is provided between the back wave surface of the bank 112 adjacent to the back wave surface of the floating body 111 and the back wave surface of the floating body 111.
It is understood that the breakwater 112 adjacent to the back wave surface of the floating body 111 may be referred to as a back wave breakwater, and there is a second predetermined distance between the back wave surface of the back wave breakwater and the back wave surface of the floating body 111. When there is one bank 112, the back wave bank and the head wave bank are the same bank. The specific value of the second preset distance is selected according to actual needs, and this embodiment does not limit this.
The first preset distance and the second preset distance may be equal or different. Preferably, the first preset distance and the second preset distance are equal. In this case, if there is one bank 112, the bank 112 is located at the middle of the floating body 11.
In practical application, the back wave surface of the bank 112 close to the back wave surface of the floating body 111 can be selected to be flush with the back wave surface of the floating body 111.
In the above-mentioned floating breakwater unit, the wave-facing surface of the breakwater 112 and the wave-facing surface of the floating body 111 may be selected to be parallel or inclined with respect to each other. Accordingly, the back wave surface of the bank 112 and the back wave surface of the floating body 111 may be selected to be parallel or inclined with respect to each other. In order to improve the wave-breaking effect, the wave-facing surface of the dam 112 and the wave-facing surface of the floating body 111 may be selected to be parallel, and the back wave-facing surface of the dam 112 and the back wave-facing surface of the floating body 111 are selected to be parallel.
In order to improve the wave-breaking effect, the wave-facing side of at least one of the breakwaters 112 and the wave-facing side of the floating body 111 may be selected to form a sloping stepped structure 113 or a curved stepped structure 114. Therefore, the capacity of breaking waves is improved, and the impact force of the waves on the floating breakwater is reduced, so that the wave-absorbing effect is improved.
It is understood that the wave-facing side of the bank 112, the wave-facing side of the floating body 111, and the step surface form the inclined stepped structure 113 or the curved stepped structure 114. If the wave-facing surface of the breakwater 112, the wave-facing surface of the floating body 111 and the step surface form an inclined-surface step structure 113, the step surface is an inclined surface, or the step surface and the wave-facing surface of the breakwater 112 are both inclined surfaces; if the wave-facing surface of the bank 112, the wave-facing surface of the floating body 111, and the step surface form a curved step structure 114, the step surface is a curved surface, or both the step surface and the wave-facing surface of the bank 112 are curved surfaces.
The inclination angle of the step surface of the inclined step structure 113 is selected according to actual needs, and this embodiment does not limit this.
In the curved surface step structure 114, a step surface of the curved surface step structure 114 is a curved surface, and for convenience of installation, the step surface of the curved surface step structure 114 may be an arc surface. The step surface of the curved step structure 114 may protrude toward the bottom side of the floating body 111 or may protrude toward the top side of the floating body 111. In order to improve the wave-absorbing effect, the steps of the curved step structure 114 may be selected to protrude toward the bottom side of the floating body 111, as shown in fig. 3, 9 and 14.
Specifically, the number of steps of the inclined step structure 113 may be one or more, and is selected according to actual needs. As shown in fig. 2, 7, 8, 12, and 13, the number of steps of the inclined stepped structure 113 is one. The number of the steps of the curved step structure 114 may be one or more, and is selected according to actual needs. As shown in fig. 3, 9 and 14, the curved stepped structure 114 has one step number.
In practical application, the wave-facing side of the dam 112 and the wave-facing side of the floating body 111, which are close to the wave-facing side of the floating body 111, may be selected to form the slope step structure 113 or the curved step structure 114.
In the above structure, if there are more than two banks 112 and there is a gap between two adjacent banks 112, in order to reduce the material consumption, the height of the floating body 111 at the gap may be selected to be smaller than the height of the lower end of the lowest slope in the slope step structure 113, or the height of the floating body 111 at the gap may be selected to be smaller than the height of the lower end of the lowest curved surface in the curved step structure 114.
In order to simplify installation, the cross-section of the constituent units of the floating breakwater may be selected to be an axisymmetric structure, in which the cross-section of the constituent units of the floating breakwater is perpendicular to the front and back surfaces of the constituent units of the floating breakwater. At the moment, the wave-facing side and the wave-backing side of the component unit of the floating breakwater do not need to be distinguished, so that the probability of mistaken installation is reduced, and the installation is simplified.
Specifically, if there is one bank 112, the back wave side of the bank 112 and the back wave side of the floating body 111 also form the slope step structure 113 or the curved step structure 114. At this time, the back wave surface of the bank 112, the back wave surface of the floating body 111, and the step surface also form the inclined step structure 113 or the curved step structure 114.
Specifically, if there are more than two breakwaters 112, the distribution direction of any two breakwaters 112 is the same as the distribution direction of the head-on and back-off surfaces in each breakwater 112, and the head-on side of the breakwater 112 near the head-on surface of the floating body 111 and the head-on side of the floating body 111 may be selected to form the inclined-plane step structure 113, the back-off side of the breakwater 112 near the back-off surface of the floating body 111 and the back-off side of the floating body 111 to form the inclined-plane step structure, or the head-on side of the breakwater 112 near the head-on surface of the floating body 111 and the head-on side of the floating body 111 may form the curved-plane step structure 114, and the back-off side of the breakwater 112 near the back-off surface of the floating body 111 and the back-off side of the floating body 111 may form the curved-plane step structure 114.
In practical application, the cross section of the above-mentioned floating breakwater unit may be non-axisymmetric, and is not limited to the above-mentioned embodiment.
Specifically, if the back wave surface of the breakwater 112 close to the back wave surface of the floating body 111 is flush with the back wave surface of the floating body 111, the front wave side and the back wave side of the whole constituent unit are conveniently distinguished, the probability of mistaken installation is effectively reduced, and thus the installation is simplified.
In the above-described floating breakwater unit, the shape and size of the floating body 111 and the bank 112 are selected according to actual needs. For convenience of production and manufacture, the bank 112 and the floating body 111 may be selected to have a rectangular parallelepiped shape. Further, the floating body 111 may have a square shape.
Of course, the floating body 111 and the bank 112 may have other shapes, for example, the floating body 111 may have a circular shape, and the bank 112 may have a columnar shape.
In the above-mentioned floating breakwater's component unit, to the distribution direction of the face of the rising wave and the face of the back of the sea, select according to the actual need. For example, the wave-facing surface and the wave-backing surface of the breakwater 112 are sequentially distributed in the width direction of the breakwater 112, and the wave-facing surface and the wave-backing surface of the floating body 111 are sequentially distributed in the width direction of the floating body 111; or, the wave-facing surface and the back wave-facing surface of the breakwater 112 are sequentially distributed along the length direction of the breakwater 112, and the wave-facing surface and the back wave-facing surface of the floating body 111 are sequentially distributed along the length direction of the floating body 111. The former is preferred in order to reduce costs.
If the wave-facing surface and the back wave-facing surface of the dam 112 are sequentially distributed along the width direction of the dam 112, and the wave-facing surface and the back wave-facing surface of the floating body 111 are sequentially distributed along the width direction of the floating body 111, in order to improve the wave-absorbing effect, the end surface of the dam 112 in the length direction may be selected to be flush with the end surface of the floating body 111 in the length direction. Of course, the end surface of the bank 112 in the longitudinal direction and the end surface of the floating body 111 in the longitudinal direction may be not flush with each other, and is not limited to the above embodiment.
It is understood that the end surface of the dam 112 in the length direction is perpendicular to the length direction of the dam 112, and the end surface of the floating body 111 in the length direction is perpendicular to the length direction of the floating body 111.
The above-described constituent units of the floating breakwater are required to be connected with the mooring system 13, and particularly, the buoyant body 111 and/or the dam 112 are provided with mooring connectors for connection with the mooring system 13.
For the specific structure of the mooring connector, it is selected according to actual needs, for example, the mooring connector is a retaining ring, which is not limited in this embodiment.
In order to more specifically describe the technical solution provided by the embodiment, the following description is made according to a specific structure.
Example one
As shown in fig. 1 to 3, in one embodiment, a floating breakwater comprises: a floating body 111, a bank 112 fixed to the top of the floating body 111; the breakwater 112 is located between the wave-facing surface and the back wave-facing surface of the floating body 111, the distance between the wave-facing surface and the back wave-facing surface of the breakwater 112 is smaller than the distance between the wave-facing surface and the back wave-facing surface of the floating body 111, a first preset distance is reserved between the wave-facing surface of the breakwater 112 and the wave-facing surface of the floating body 111, and the back wave-facing surface of the breakwater 112 is flush with the back wave-facing surface of the floating body 111.
As shown in fig. 2, the wave-facing side of the bank 112 and the wave-facing side of the floating body 111 form an inclined-plane step structure 113; as shown in fig. 3, the wave-facing side of the bank 112 and the wave-facing side of the floating body 111 form a curved stepped structure 114.
Example two
As shown in fig. 4 to 9, the floating breakwater according to the second embodiment is different from the first embodiment in that the dam 112 is located at the middle of the floating body 111. At this time, the unit of the floating breakwater is in an inverted T shape.
As shown in fig. 7, the wave-facing side of the breakwater 112 and the wave-facing side of the floating body 111 form a slope step structure 113, and the back wave side of the breakwater 112 and the back wave side of the floating body 111 also form a slope step structure 113. As shown in fig. 8, the wave-facing side of the bank 112 and the wave-facing side of the floating body 111 form a slope step structure 113. As shown in fig. 9, the wave-facing side of the breakwater 112 and the wave-facing side of the floating body 111 form a curved stepped structure 114, and the back wave side of the breakwater 112 and the back wave side of the floating body 111 also form a curved stepped structure 114.
As shown in fig. 6, when incident waves move and interact with the constituent units of the floating breakwater, the dam 112 reflects the incident wave energy to the open sea to reduce transmitted waves, completing the wave-damping action.
Through simulation and verification, under the same draft, the same width and the same wave condition, the wave-absorbing effect of the floating breakwater composition unit provided by the second embodiment is not less than 73%, and the wave-absorbing effect of the existing box-type floating breakwater is 50%, so that the wave-absorbing effect of the floating breakwater composition unit provided by the second embodiment is at least improved by 23%. Specifically, in simulation checking calculation, the wave height of the wave element is 2.0m, the period of the wave element is 6s, the water depth of the water pool is 9m, and the width of the component unit of the floating breakwater is 10 m. Therefore, the floating breakwater provided by the second embodiment has a good wave-absorbing effect and a strong adaptability to larger waves, i.e. can resist the larger waves from crossing. It can be understood that the width direction of the constituent units of the floating breakwater is parallel to the direction of the arrangement of the head-on and back-on surfaces of the constituent units of the floating breakwater.
According to calculation, under the same width, the mass of the component unit of the floating breakwater provided by the second embodiment is reduced by at least 35% compared with that of the existing component unit, and the manufacturing cost is reduced.
EXAMPLE III
As shown in fig. 10 to 14, the floating breakwater according to the third embodiment is different from the second embodiment in that two breakwaters 112 are provided, a first predetermined distance is provided between the wave-facing surface of the breakwater 112 adjacent to the wave-facing surface of the floating body 111 and the wave-facing surface of the floating body 111, and a second predetermined distance is provided between the back wave-facing surface of the breakwater 112 adjacent to the back wave-facing surface of the floating body 111 and the back wave-facing surface of the floating body 111.
As shown in fig. 12, the wave-facing side of the breakwater 112 and the wave-facing side of the floating body 111 form a slope step structure 113, and the back wave side of the breakwater 112 and the back wave side of the floating body 111 also form a slope step structure 113. As shown in fig. 13, the wave-facing side of the bank 112 and the wave-facing side of the floating body 111 form a slant step structure 113. As shown in fig. 14, the wave-facing side of the breakwater 112 and the wave-facing side of the floating body 111 form a curved stepped structure 114, and the back wave side of the breakwater 112 and the back wave side of the floating body 111 also form a curved stepped structure 114.
As shown in fig. 11, when an incident wave moves and interacts with the constituent units of the floating breakwater, the first breakwater 112 performs a first wave-damping action on the incident wave and reflects the energy of the incident wave to the open sea to reduce the transmitted wave, and the first wave-damping action has a better attenuation effect for waves with a smaller wave height; for waves with higher wave heights, the waves pass through the first breakwater 112 with a certain probability, at the moment, the second breakwater 112 carries out secondary wave elimination on the waves passing through the first breakwater 112 and blocks the waves from passing through the whole structure, meanwhile, the blocked waves can move in the forming unit of the floating breakwater, kinetic energy is given to the whole structure and is counteracted with incident wave energy, and the energy of the incident waves is further weakened.
Through simulation and verification, under the same draft, the same width and the same wave condition, the wave absorption effect of the component unit of the floating breakwater provided by the third embodiment is not less than 70%, and the wave absorption effect of the existing component unit is 50%, so that the wave absorption effect of the component unit of the floating breakwater provided by the third embodiment is at least improved by 20%. Specifically, in simulation checking calculation, the wave height of the wave element is 2.0m, the period of the wave element is 6s, the water depth of the water pool is 9m, and the width of the component unit of the floating breakwater is 10 m. Therefore, the floating breakwater provided by the third embodiment has a good wave-absorbing effect and strong adaptability to large waves, and can effectively weaken the transmissivity of the large waves, so that the breakwater can resist the large waves from crossing. It can be understood that the width direction of the constituent units of the floating breakwater is parallel to the direction of the arrangement of the head-on and back-on surfaces of the constituent units of the floating breakwater.
According to calculation, under the same width, the mass of the component unit of the floating breakwater provided by the third embodiment is reduced by at least 30% compared with that of the existing component unit, and the manufacturing cost is reduced.
Based on the above-mentioned embodiments of the constituent units of the floating breakwater, this embodiment also provides a floating breakwater, as shown in fig. 15 and 16, the floating breakwater includes a plurality of constituent units 11 connected in sequence, and the constituent units 11 are the above-mentioned embodiments of the floating breakwater. It will be appreciated that any two constituent elements 11 have an angle between their direction of distribution and their direction of wave, which angle is not zero.
Since the above-mentioned embodiments provide the constituent units of the floating breakwater having the above-mentioned technical effects, and the above-mentioned floating breakwater includes the above-mentioned constituent units of the floating breakwater, the above-mentioned floating breakwater also has corresponding technical effects, and the details thereof are not described herein again.
In the floating breakwater, any two constituent units 11 may be the same or different. As shown in fig. 15 and 16, the two constituent units 11 are identical.
Specifically, two adjacent constituent units 11 are connected by a connection structure 12, and the connection structure 12 may be a flexible connection structure, a semi-flexible connection structure, or a rigid connection structure, and is selected according to actual needs, which is not limited in this embodiment.
