Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a prefabricated UHPC water floating device. Background Art

[0002] Wind power generation can be divided into onshore wind power and offshore wind power. The technologies of onshore wind power and photovoltaic power generation have become increasingly mature, but offshore wind power and photovoltaic power generation are still in the experimental research stage.

[0003] The main problems faced by offshore wind power and photovoltaic power generation are how to build a reliable offshore comprehensive test platform. At present, traditional offshore floating platforms mostly use plastic floating barrels or floating boxes as the main stress devices, but these devices often have disadvantages such as poor durability, high cost, easy aging, and difficult maintenance. Moreover, due to the weak overall connection of the devices, it is difficult to adapt to the combined action of environmental loads such as static loads, wind waves, and currents in the ocean, which is not conducive to the construction and development of ocean engineering. Summary of the Invention

[0004] In view of this, the present invention provides a prefabricated UHPC water floating device. The overall stability of the device is strong, and each component of the device is prefabricated by a mold, which can be easily spliced and disassembled without large-scale offshore operations, and has a wide range of applications.

[0005] The present invention is realized by the following technical solutions:

[0006] A prefabricated UHPC water floating device includes a floating system, an anchoring system, and an anti-impact system; the floating system is composed of a plurality of floating boxes that overlap each other, and a connection groove is provided between the floating boxes; the anchoring system includes a fixed pile, a connection block, and a traction line.

It can be applied to complex marine environments, meet the needs of various projects, and an anti-impact system is added around the periphery of the floating system to enhance the device's ability to resist wind and waves.

[0009] Furthermore, the several floating boxes are divided into a central floating box, splicing floating boxes, and guiding floating boxes; the central floating box is arranged at the center of the floating system, and the splicing floating boxes are arranged around the central floating box; the guiding floating boxes are arranged between the splicing floating boxes and are used to connect the splicing floating boxes and the central floating box. The central floating box is the reference point of the floating system, the splicing floating boxes are the main floating box form for splicing the floating system, and the main function of the guiding floating boxes is to assist in connecting the splicing floating boxes.

[0010] Furthermore, splicing blocks and splicing grooves are arranged on the outer side of the floating box, and the floating boxes are lap-fixed through the splicing blocks and splicing grooves. One side of the floating box with a splicing block is lap-fixed with one side of another floating box with a splicing groove, so as to realize the fixation of the two floating boxes. The number of splicing blocks and splicing grooves on each outer side of the floating box is set according to needs, and the scale of the floating system can be extended by lapping the floating boxes.

[0011] Furthermore, the floating box is of an empty box structure, and partition boards are arranged inside it in a vertical and horizontal distribution.

[0034] Please refer to Figure 1 , this embodiment provides an assembled UHPC water - floating device, including a floating system 3, an anchoring system 1, and an anti - impact system 2. The floating system 3 is placed on the water surface to bear the external load. The anti - impact system 2 is arranged around the outside of the floating system 3 to weaken the impact of the waves and at the same time transmit the impact to the floating system 3. The anchoring system 1 restricts the displacement of the floating system 3 in the water surface direction.

[0035] Specifically, as Figures 2 - 5As shown in the figure, the floating system 3 is composed of a plurality of floating boxes lapped together. After lapping, a connecting groove 34 is formed between the floating boxes. The interior of the floating box adopts an empty box structure, with transverse partitions and longitudinal partitions arranged inside, thereby dividing the interior of the floating box into a plurality of inner cabins. In this embodiment, the plurality of floating boxes are divided into a central floating box 31, a splicing floating box 32, and a guiding floating box 33. The difference between the central floating box 31, the splicing floating box 32, and the guiding floating box 33 lies in that different numbers of first splicing blocks 35 and splicing grooves 36 are provided on the side walls of the floating boxes in contact with the water surface. For example, two sets of symmetric surfaces on the side wall of the splicing floating box 32 are respectively provided with the first splicing block 35 and the splicing groove 36. Three sides of the side wall of the guiding floating box 33 are provided with the splicing groove 36 and one side is provided with the first splicing block 35. Splicing grooves 36 are opened on all four side walls of the central floating box 31. The central floating box 31 is at the central position of the floating system 3. The splicing floating box 32 is the main form of the floating box of the floating system 3. It is arranged neatly in a circular arrangement to form four groups of blocks, and the four groups of blocks are arranged around the four corners of the central floating box 31. The function of the guiding floating box 33 is to assist in connecting the splicing floating boxes 32. It is arranged between the splicing floating boxes 32 of the group of blocks. The first splicing block 35 on the side surface of the outermost splicing floating box 32 of the group of blocks is lapped on the splicing groove 36 of the guiding floating box 33, and the two groups of blocks are arranged symmetrically along the guiding floating box 33. During the assembly of the floating system 1 during the construction process, the specific combination form of the floating system 3 refers to Figure 2 , during the construction, the construction personnel first place the central floating box 31 as a reference point, and then around the central floating box 31, a plurality of splicing floating boxes 32 are lapped with each other through the first splicing block 35 and the splicing groove 36 to form four groups of blocks. The four groups of blocks are Figure 2 the structure surrounded by the splicing floating box 32 in

[0036] Specifically, as Figure 2 and Figure 6 shown, the anchoring system 1 includes a connecting block 11, a towing line 12, and a fixed pile 13. The bottom end of the fixed pile 13 is vertically fixed to the seabed, providing an anchoring point for the floating system 1. The connecting block 11 is embedded in the connecting groove 34 of the floating system 1 to fill the gap existing between the floating boxes, and at the same time plays a role in transmitting force in the horizontal direction and a connecting role in the vertical direction of the anchoring system 1. One end of the towing line 12 is fixed to the top end of the fixed pile 13, and the other end is fixedly connected to the bottom end of the connecting block 11 to realize the pulling and restraint of the floating system 3, forming a complete anchoring system 1.

[0037] Specifically, as Figure 2 , Figure 7 and Figure 8As shown in the figure, the shock-proof system 2 includes a variety of wave-dissipating blocks with different structures, which can be divided into the first wave-dissipating block 21, the second wave-dissipating block 22, the third wave-dissipating block 23 and the fourth wave-dissipating block 24; the first wave-dissipating block 21 is a columnar structure with a triangular vertical cross-section, and the plane where the hypotenuse of the triangle is located is a concave arc surface. The concave arc surface contacts the sea level, which can reduce the wave current and weaken the impact of the waves. Moreover, a second splicing block 28 and a plug-in block 29 are arranged on a plane of the first wave-dissipating block 21 away from the concave arc surface. The first wave-dissipating block 21 is inserted and fixed with the splicing groove 36 of the splicing floating box 32 through the second splicing block 28. At the same time, the plug-in block 29 is inserted into the connection groove 34, so as to be tightly fixed with the outermost splicing floating box 32 of the floating system 3, realizing the surrounding of the floating system 1; the structure of the second wave-dissipating block 22 is similar to that of the first wave-dissipating block 21, but the position where the plug-in block 29 is set is different. Specifically, as Figure 7 shown, in this embodiment, the plug-in block 29 of the first wave-dissipating block 21 is arranged at the leftmost side of the side where the second splicing block 28 is located, and is arranged parallel to the second splicing block 28. The plug-in block 29 of the second wave-dissipating block 22 is arranged at the rightmost side of the side where the second splicing block 28 is located; the structure of the third wave-dissipating block 23 is similar to that of the first wave-dissipating block 21 and the second wave-dissipating block 22, but only the second splicing block 28 is arranged on the side of the third wave-dissipating block 23. Specifically, as Figure 6 shown; the fourth wave-dissipating block 24 is a triangular pyramid structure, and the plane where the hypotenuse of the triangle is located is a concave arc surface; in addition, as Figure 7 and Figure 8 shown, two plug-in card slots 25 are convexly arranged on the top surfaces of the first wave-dissipating block 21, the second wave-dissipating block 22, the third wave-dissipating block 23 and the third wave-dissipating block 24; the two plug-in card slots 25 of the first wave-dissipating block 21, the second wave-dissipating block 22 and the third wave-dissipating block 23 are arranged in parallel on the opposite sides of their top surfaces close to the side where the second splicing block 28 is located. When multiple wave-dissipating blocks are spliced and installed, the first wave-dissipating block 21, the second wave-dissipating block 22 and the third wave-dissipating block 23 are connected and fixed to each other by inserting the strip-shaped card block 26 into the plug-in card slot 25; the two plug-in card slots of the fourth wave-dissipating block 24 are perpendicularly arranged on the side edges of its top surface. The fourth wave-dissipating block 24 is fixedly connected with the adjacent wave-dissipating block by passing the U-shaped card block through the two plug-in card slots 25. The specific plug-in and fixing method is as Figure 2 shown.

[0038] Based on the above scheme, the assembly process of the device is as follows:

[0039] First, the construction workers first determine the positions of the fixed piles 13 and anchor them. Then, taking the central floating box 31 as the reference point, the floating box 32 and the guiding floating box 33 are lapped and spliced to form the floating system 3. At the same time, the connecting block 11 is embedded in the floating system 3, so as to connect the fixed pile 13 with the floating system 3. Finally, the first wave-blocking blocks 21, the second wave-blocking blocks 22, the third wave-blocking blocks 23 and the fourth wave-blocking blocks 24 are arranged and installed on the outside of the floating system 3. The first wave-blocking blocks 21, the second wave-blocking blocks 22, the third wave-blocking blocks 23 and the fourth wave-blocking blocks 24 are combined and arranged around the floating system 3 to form the impact-proof system 2. The floating system 3 is tightly connected with the impact-proof system 2 to form the force-bearing main body.

[0040] In this embodiment, the central floating box 31, the spliced floating box 32 and the guiding floating box 33 of the floating system 3 are box structures precast from UHPC ultra-high performance concrete. Their overall self-weight is light, the overall stability of the formed floating system is strong, and the internal of the floating box is provided with load-bearing partitions, which can bear large load effects in all directions; the fixed pile 13 and the connecting block 11 of the anchoring system 1 are also precast from UHPC ultra-high performance concrete. UHPC ultra-high performance concrete has high strength, its compressive strength can reach 140 - 160 MPa, it has large load-bearing capacity, low porosity, dense structure, good durability, low cost, long service life, and does not pollute the surrounding environment.

[0041] The force-bearing characteristics of the floating system 3 depend on the type of floating box used and the connection method between the floating boxes. In other embodiments, the size of the floating system 3 can be extended according to the construction requirements, and the splicing and combination method of the floating boxes can also be designed and combined according to the actual engineering requirements to adapt to the complex marine environment.

[0042] Preferably, as Figure 5 shown, in order to improve the stability of the device, both the first splicing block 35 and the second splicing block 28 are set as tenons with a narrow inner width and a wide outer width similar to dovetail tenons, while the splicing groove 36 is set as a mortise with a wide inner width and a narrow outer width. The first splicing block 35 or the second splicing block 28 is inserted into the splicing groove 36 from above, and the two are tightly clamped and fixed to each other. When the floating platform rises and falls due to the waves, the first splicing block 35 or the second splicing block 28 cannot break away from the splicing groove 36 in the horizontal direction, thus effectively improving the stability of the device.

[0043] Considering the complex and changeable water flow environment and the different impact forces brought by wave currents of different degrees, multiple traction lines 12 and connecting blocks 11 can be simultaneously arranged at the top of the fixed pile 13 in the anchoring system 1. The connecting block 11 is embedded in the connecting groove 34 of the floating system 3, making the overall floating system 3 more integral, and at the same time reducing the tension on each traction line 12; in addition, multiple anchoring systems 1 can also be installed on the floating system 3 simultaneously, as Figure 1As shown, 4 anchoring systems 1 are provided in this embodiment, making the floating system 3 more stable and impact-resistant.

[0044] Preferably, as Figure 2 and Figure 4 shown, 4 anti-disengagement blocks 14 are vertically provided at the top of the connection block 11. The anti-disengagement blocks 14 are in the shape of circular plates. When the connection block 11 is embedded in the connection groove 34 of the floating system 3, the anti-disengagement blocks 14 contact the top surface of the splicing floating box 32 to restrain the connection block 11, enhancing the integrity of the anchoring system 1 and the floating system 3 and preventing the connection block 11 from detaching from the floating system 3 under the impact of waves and currents.

[0045] The floating box, wave protection block, fixed pile and connection block can all be prefabricated by molds and mass-produced, and each prefabricated structure is flat, making the overall stability of the formed floating device good.

[0046] The various technical features in the above embodiments can be combined arbitrarily as long as there is no conflict or contradiction between the features. However, due to space limitations, they are not described one by one.

[0047] The above is only a partial embodiment of the present invention and does not limit the implementation manner and protection scope of the present invention. For those skilled in the art, it should be realized that the solutions obtained by equivalent substitution and obvious changes made by using the content of the specification of the present invention should be included in the protection scope of the present invention.
