Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, fig. 1 is a cross-sectional view of an overall structure of an embodiment of the present utility model, and fig. 2 is a top view of fig. 1.

In one embodiment of the utility model, the pile foundation anti-floating ice wave protection device mainly comprises an inner mounting ring 2, an elastic piece 3 and an outer protection ring 4.

The inner mounting ring 2 is annular, is integrally sleeved on the pile foundation 1 of the water photovoltaic power station, is connected with the pile foundation 1, and is mainly used as a basic mounting component of the device for mounting other parts.

The outer protection ring 4 is integrally arranged outside the pile foundation 1 or outside the inner installation ring 2 in a surrounding manner, is not directly covered outside the inner installation ring 2, but keeps a certain distance with the inner installation ring 2 to form an inner and outer two-layer structure, and the elastic piece 3 is arranged in an inner and outer gap between the inner installation ring 2 and the outer protection ring 4. The outer protecting ring 4 is mainly used for receiving the impact generated by the water surface floaters such as floating ice and the like, and transmitting the external impact energy inwards along the elastic piece 3 so as to prevent the water surface floaters such as floating ice and the like from directly impacting the pile foundation 1.

The elastic pieces 3 are provided in plurality, and each elastic piece 3 is arranged in the inner and outer gaps of the inner mounting ring 2 and the outer protecting ring 4 and distributed into a circle along the circumferential direction of the pile foundation 1. Meanwhile, the inner ends of the elastic pieces 3 are connected with the outer wall of the inner mounting ring 2, the outer ends of the elastic pieces 3 are connected with the inner wall of the outer protecting ring 4, and the elastic pieces are mainly used for absorbing external impact energy transmitted by the outer protecting ring 4 through elastic deformation, so that the impact energy transmitted to the inner mounting ring 2 and the pile foundation 1 is greatly weakened.

In this way, the pile foundation anti-floating ice wave protection device provided by the embodiment forms double-layer physical protection on the pile foundation 1 through the outer protection ring 4 and the inner mounting ring 2, can effectively prevent water surface floaters such as floating ice from directly striking the pile foundation 1, and is borne by the outer protection ring 4 to directly strike the water surface floaters such as floating ice; meanwhile, impact energy generated by water surface floaters such as floating ice and the like to the external protection ring 4 is absorbed and weakened through elastic deformation of each elastic piece 3 in a transmission path from outside to inside, so that the impact energy transmitted to the pile foundation 1 is greatly reduced, damage to the pile foundation 1 caused by impact of external objects can be prevented, and the service life of the pile foundation 1 is prolonged.

It should be noted that, the pile foundation anti-floating ice wave protection device provided by the embodiment is not only suitable for pile foundations of offshore photovoltaic power stations, but also suitable for pile foundations of photovoltaic power stations installed on natural water bodies such as rivers, lakes and the like or artificial water bodies such as reservoirs and the like.

In an alternative embodiment with respect to the inner collar 2, the specific shape of the inner collar 2 matches the specific shape of the pile foundation 1. For example, the pile foundation 1 is cylindrical, and the inner mounting ring 2 is circular; the pile foundation 1 is square column-shaped, and the inner mounting ring 2 is rectangular ring-shaped.

Meanwhile, considering that one end of each elastic member 3 is connected to the outer wall of the inner mounting ring 2, and the other end of each elastic member 3 is connected to the inner wall of the outer protection ring 4, in order to facilitate stable connection between the elastic member 3 and the inner mounting ring 2 and between the elastic member 3 and the outer protection ring 4, in this embodiment, the cross-sectional shapes of the inner mounting ring 2 and the outer protection ring 4 are specifically rectangular. The outer wall surface of the inner mounting ring 2 and the inner wall surface of the outer protection ring 4 are arc surfaces with certain widths and larger areas, so that the stable mounting of the elastic piece 3 is facilitated; when the outer wall area of the outer protection ring 4 is increased, the direct contact area between the outer protection ring 4 and the water surface floaters such as floating ice is larger, so that the pile foundation 1 can resist the impact of the water surface floaters such as floating ice more perfectly.

As shown in fig. 4, fig. 4 is a schematic view showing a specific structure of the elastic member 3.

Further, end plates 31 may be provided at both ends of each elastic member 3 to be connected to the outer wall surface of the inner mounting ring 2 or the inner wall surface of the outer protection ring 4 through the end plates 31. In this way, the end plates 31 can be covered on the outer wall surface of the inner mounting ring 2 or the inner wall surface of the outer protection ring 4, and then the two ends of the elastic member 3 are respectively connected with the two end plates 31. Compared with the structure that the two ends of the elastic piece 3 are directly connected with the outer wall surface of the inner mounting ring 2 or the inner wall surface of the outer protecting ring 4, the indirect connection through the end plate 31 is more stable and convenient.

In an alternative embodiment with respect to the inner collar 2, it is contemplated that after absorption of external impact energy by the elastic member 3, a small portion will be transferred to the inner collar 2 and finally to the pile foundation 1. In this regard, in the present embodiment, the inner mounting ring 2 is specifically an elastic ring to absorb the impact energy transmitted by the elastic member 3 by elastic deformation of the elastic ring. Generally, the inner mounting ring 2 can be made of foam plastic or other light materials, and is covered with flexible materials such as canvas, and meanwhile, an inner filling material structure is adopted instead of a traditional inflatable structure, so that the inner mounting ring 2 can be prevented from being normally used due to air leakage when the outer wrapping material is damaged. So set up, utilize the absorption of inner collar 2 to impact energy, further weakened the impact energy who transmits to pile foundation 1 on the basis of elastic component 3, improved the protection effect.

Moreover, considering that the water surface height of the water body such as ocean is generally fluctuated, if the inner mounting ring 2 is fixed on the pile foundation 1, when the condition that the water surface descends to be far away from the inner mounting ring 2 or ascends to submerge the inner mounting ring 2 occurs, the adjacent water surface area of the pile foundation 1 is exposed, water surface floaters such as floating ice can directly strike the pile foundation 1, and effective protection cannot be formed on the pile foundation 1 at the moment. In this embodiment, the inner installation ring 2 floats on the water surface, and a clearance fit is formed between the inner edge of the inner installation ring 2 and the outer edge of the pile foundation 1, so that the inner installation ring 2 can vertically slide around the pile foundation 1, and the inner installation ring 2 has a vertical motion degree of freedom, so that when the water surface height fluctuates, the inner installation ring 2 can synchronously lift and lower relative to the pile foundation 1 along with the lifting motion of the water surface, and further the outer protection ring 4 is driven to synchronously lift and lower. So set up, no matter how the surface of water height changes, the mounted position of interior collar 2 and outer protection ring 4 on pile foundation 1 always changes with the surface of water height synchronization to guarantee to form effective protection to pile foundation 1 in surface of water region all the time.

Of course, the outer protecting ring 4 can also float on the water surface like the inner mounting ring 2, and in order to enhance the buoyancy, a floating body made of high-density polyethylene can be adopted, and the high-density polyethylene has enough toughness, strength, corrosion resistance and moisture resistance, and other similar materials can be adopted.

In an alternative embodiment with respect to the inner mounting ring 2 and the outer guard ring 4, it is contemplated that when the volume or height of the surface float such as ice is large and exceeds the guard height of the outer guard ring 4, it is possible to strike the area of the pile foundation 1 above the outer guard ring 4. In this embodiment, the inner mounting ring 2 and the outer protection ring 4 are provided with multiple layers, such as 2 layers or 3 layers, along the height direction, so as to improve the protection height and protection range of the pile foundation 1 through the multiple layers of the outer protection rings 4.

Meanwhile, in order to prevent water surface floaters such as floating ice from entering from the gap between two adjacent outer protecting rings 4 and striking the pile foundation 1, an outer ring plate 5 is additionally arranged in the embodiment. Specifically, the outer ring plate 5 is connected between the opposite end surfaces of the two adjacent outer protection rings 4, and is mainly used for covering and protecting the space between the opposite end surfaces of the two adjacent outer protection rings 4, so as to prevent floating objects on water surface such as floating ice from striking the pile foundation 1 between the two adjacent outer protection rings 4. Generally, the top end of the outer ring plate 5 is embedded in the bottom end face of the outer protection ring 4 located at the upper layer, and the bottom end of the outer ring plate 5 is embedded in the top end face of the outer protection ring 4 located at the lower layer.

As shown in fig. 3, fig. 3 is a schematic view showing a specific structure of the outer ring plate 5 or the inner ring plate 6.

In another specific embodiment provided by the utility model, considering that the pile foundation 1 of the water photovoltaic power station faces impact of waves besides collision threat of water floats such as floating ice, when the waves strike the pile foundation 1, the generated impact force can cause the pile foundation 1 to be subjected to shearing load, and surface damage easily occurs when the pile foundation is used for a long time. In this embodiment, the outer ring plate 5 is specifically a wave dissipating plate, and a plurality of meshes 7 are formed in the outer ring plate 5 to decompose and weaken waves through the meshes 7, so that the waves entering the outer ring plate 5 are reduced, the impact of the waves on the surface of the pile foundation 1 is weakened, and the damage of the waves on the surface of the pile foundation 1 is reduced.

Further, it is contemplated that there is a gap between the inner and outer guard rings 2, 4, and that a small portion of the waves may enter the outer guard ring 4 from the gap, thereby bypassing the outer guard ring 4 and directly impacting the surface of the pile foundation 1. For this, an inner ring plate 6 is added in this embodiment. Similarly, the inner ring plate 6 is connected between the opposite end surfaces of the protection rings in the adjacent two layers, and is mainly used for covering and protecting the space between the opposite end surfaces of the protection rings in the adjacent two layers. Meanwhile, the inner-layer annular plate 6 is specifically a wave-dissipating plate, and a plurality of meshes 7 are formed in the inner-layer annular plate 6 so as to decompose and weaken waves entering the outer-layer annular plate 5 through the meshes 7, reduce waves directly contacting the surface of the pile foundation 1, weaken impact of the waves on the surface of the pile foundation 1, and reduce damage of the waves on the surface of the pile foundation 1. Generally, the top end of the inner ring plate 6 is embedded in the bottom end face of the inner protection ring located at the upper layer, and the bottom end of the inner ring plate 6 is embedded in the top end face of the inner protection ring located at the lower layer.

To sum up, the anti-floating ice wave protection device for the pile foundation provided by the embodiment not only can prevent the damage of the pile foundation 1 caused by the impact of external objects such as floating ice, but also can greatly reduce the impact damage of the wave slapping on the surface of the pile foundation 1 and improve the service life of the pile foundation 1.

As shown in fig. 5, fig. 5 is a schematic view of a split structure of the inner mounting ring 2 and the outer protection ring 4.

In addition, considering that both ends about pile foundation 1 are all closed, can't directly slide in interior collar 2 from the one end of pile foundation 1, to this, in order to be convenient for install interior collar 2 on pile foundation 1, interior collar 2 in this embodiment is split type structure specifically. Specifically, the inner mounting ring 2 mainly includes a first inner ring 21 and a second inner ring 22. The central angles (equivalent central angles when the first inner ring 21 and the second inner ring 22 are rectangular rings) are 180 degrees, that is, the first inner ring 21 and the second inner ring 22 are semicircular rings, and can be spliced into a whole ring (circular ring or rectangular ring). Meanwhile, the first clamping grooves 23 are formed on the end surfaces of the two ends of the first inner ring 21, and the first clamping convex strips 24 are formed on the end surfaces of the two ends of the second inner ring 22. The first clamping groove 23 can form a concave-convex clamping fit with the first clamping convex strip 24, so that the two end surfaces of the first inner ring 21 and the two end surfaces of the second inner ring 22 are connected and fixed into a whole. So set up, when installing inner collar 2 on pile foundation 1, only need first inner ring 21 and second inner ring 22 half cover respectively on pile foundation 1 earlier, with first joint recess 23 and the first joint sand grip 24 on first inner ring 21 and the second inner ring 22 formation joint each other, can splice into complete inner collar 2 to the ring cover is on pile foundation 1.

Of course, the inner mounting ring 2 is not limited to a split structure in which two 180 ° inner rings are spliced with each other, but may be a split structure in which three 120 ° inner rings, four 90 ° inner rings, or the like are further split and spliced with each other.

Generally, the first clamping grooves 23 are uniformly formed on the end surfaces of the two ends of the first inner ring 21 along the width direction (or the radial direction), and the first clamping grooves 23 are actually long sliding grooves extending along the vertical direction (or the axial direction) because the first inner ring 21 has a certain thickness (or height). Similarly, the first clamping convex strips 24 are uniformly arranged on the two end surfaces of the second inner ring 22 along the width direction (or the radial direction), and the first clamping convex strips 24 are long sliding strips extending along the vertical direction (or the axial direction) because the second inner ring 22 has a certain thickness (or height). So set up, when the concatenation, only need place the second inner ring 22 in the position that is higher than (or is less than) first inner ring 21, then make each first joint sand grip 24 align each first joint recess 23 respectively after, the second inner ring 22 of vertical dip (or rise) again to the same high position with first inner ring 21, can make each first joint recess 23 and each first joint sand grip 24 form joint cooperation simultaneously, accomplish the concatenation operation.

In addition, the cross-sectional shapes of the first clamping groove 23 and the first clamping convex strip 24 are specifically tooth-shaped, triangular or trapezoid, and the like, so that the first inner ring 21 and the second inner ring 22 can be prevented from generating relative displacement in the horizontal direction after being spliced.

As shown in fig. 6, fig. 6 is a schematic end view of the inner mounting ring 2 or the outer protection ring 4.

Furthermore, in order to enhance the clamping stability between the first clamping groove 23 and the first clamping convex strip 24 and prevent the two from generating vertical relative displacement, a first pit 231 and a first protrusion 241 are added in this embodiment. Wherein, the first pit 231 is formed on the bottom surface of the first clamping groove 23, and a plurality of pits are arranged at the same time. The first protrusions 241 are disposed on the top surface of the first clamping protrusion 24, and are simultaneously disposed in plurality. When the first clamping groove 23 and the first clamping convex strip 24 form clamping fit, each first pit 231 and each first protrusion 241 form concave-convex fit at the same time, and the concave-convex fit is mainly used for increasing the contact area between the first clamping groove 23 and the first clamping convex strip 24, so that the friction force between the first clamping groove 23 and the first clamping convex strip 24 is enhanced, and the relative sliding of the first clamping groove 23 and the first clamping convex strip 24 is prevented.

Generally, the first concave pit 231 and the first convex 241 may each have a spherical shape. Of course, the first recess 231 and the first protrusion 241 may have other shapes, such as arc, rectangle, etc.

Similarly, for the outer guard ring 4, to facilitate the mounting of the outer guard ring 4 on the inner mounting ring 2, the outer guard ring 4 in this embodiment is specifically a split structure. Specifically, the outer guard ring 4 mainly includes a first outer ring 41 and a second outer ring 42. The central angles (equivalent central angles when the first outer ring 41 and the second outer ring 42 are rectangular rings) are 180 degrees, that is, the first outer ring 41 and the second outer ring 42 are semicircular rings, and can be spliced into a whole ring (circular ring or rectangular ring). Meanwhile, the second clamping grooves 43 are formed on the end surfaces of the two ends of the first outer ring 41, and the second clamping convex strips 44 are formed on the end surfaces of the two ends of the second outer ring 42. The second clamping groove 43 and the second clamping convex strip 44 form a concave-convex clamping fit, so that the two end surfaces of the first outer ring 41 and the two end surfaces of the second outer ring 42 are connected and fixed into a whole. So set up, when installing outer protection ring 4 on pile foundation 1, only need first with the inner wall of first outer ring 41 and second outer ring 42 link to each other with the outer end of each elastic component 3 respectively, with second joint recess 43 and the second joint sand grip 44 on first outer ring 41 and the second outer ring 42 form the joint each other, can splice into complete outer protection ring 4 to the ring cover is on inner installation ring 2.

Of course, the outer protection ring 4 is not limited to a split structure in which two 180 ° outer rings are spliced with each other, but may be a split structure in which three 120 ° outer rings, four 90 ° outer rings, or more split structures are spliced with each other.

Generally, the second clamping grooves 43 are uniformly formed on the end surfaces of the two ends of the first outer ring 41 along the width direction (or the radial direction), and the second clamping grooves 43 are actually long sliding grooves extending along the vertical direction (or the axial direction) because the first outer ring 41 has a certain thickness (or height). Similarly, a plurality of second clamping convex strips 44 are uniformly arranged on the end surfaces of the two ends of the second outer ring 42 along the width direction (or the radial direction), and the second clamping convex strips 44 are long sliding strips extending along the vertical direction (or the axial direction) because the second outer ring 42 has a certain thickness (or height). So set up, when the concatenation, only need place the second outer loop 42 in the position that is higher than (or is less than) first outer loop 41, then make each second joint sand grip 44 align each second joint recess 43 respectively after, the second outer loop 42 of vertical decline (or rise) again to the same high position with first outer loop 41, can make each second joint recess 43 and each second joint sand grip 44 form joint cooperation simultaneously, accomplish the concatenation operation.

In addition, the cross-sectional shapes of the second engaging groove 43 and the second engaging protruding strip 44 are specifically tooth-shaped, triangular or trapezoidal, and the like, so that the first outer ring 41 and the second outer ring 42 can be prevented from being relatively displaced in the horizontal direction after being spliced.

Furthermore, in order to enhance the locking stability between the second locking groove 43 and the second locking protrusion 44 and prevent the two from generating vertical relative displacement, in this embodiment, a second recess 431 and a second protrusion 441 are added. The second recess 431 is formed on the bottom surface of the second engaging groove 43, and a plurality of second recesses are formed therein. The second protrusions 441 are disposed on the top surface of the second engaging protruding strips 44, and a plurality of second protrusions are disposed at the same time. When the second clamping groove 43 and the second clamping convex strip 44 form a clamping fit, each second concave pit 431 and each second protrusion 441 form a concave-convex fit at the same time, and the concave-convex fit is mainly used for increasing the contact area between the second clamping groove 43 and the second clamping convex strip 44, so as to further enhance the friction force between the second clamping groove 43 and the second clamping convex strip 44 and prevent the two from generating relative sliding.

Generally, the second recess 431 and the second protrusion 441 may each have a spherical shape. Of course, the second recess 431 and the second protrusion 441 may have other shapes, such as an arc shape, a rectangular shape, and the like.
