Description

Technical Field

[0001] This utility model relates to a floating operation platform suitable for static load testing of pile foundations in a solar-fishery complementary project, belonging to the technical field of floating photovoltaic foundation pile testing platforms. Background Technology

[0002] As a typical model of "photovoltaic+" integrated development, the solar-fishery complementary project realizes the three-dimensional utilization of "power generation above and fish farming below" by setting up photovoltaic modules above water bodies (ponds, lakes, reservoirs, etc.), which is an important path to promote the coordinated development of new energy and traditional fisheries.

[0003] As the core supporting structure of the photovoltaic bracket in the fishery-solar complementary project, the construction quality of the pile foundation directly affects the stability and service life of the photovoltaic system. Therefore, it is necessary to conduct static load tests on the pile foundation to simulate actual loads and test the vertical bearing capacity, pull-out force and settlement performance of the pile foundation to ensure that the load requirements of the photovoltaic bracket (such as wind and snow loads, component self-weight, etc.) are met.

[0004] Currently, static load tests on pile foundations for solar-aquaculture complementary projects require transporting personnel and tools to the lake for the work. Existing transport platforms used for static load tests on pile foundations in solar-aquaculture complementary projects, such as the floating platform in the combined device and method for vertical static load tests using the floating anchor pile method disclosed in CN116163347A, suffer from drawbacks. This is because the construction of such a platform requires numerous components, including a main frame, buoyancy tank, adjustable hinged plates, guardrails, and steel gratings. Furthermore, the construction process involves numerous tools for welding and cutting, resulting in cumbersome assembly, time and labor consumption, limited carrying capacity, high cost, and inconvenient road transport. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the existing technology, this utility model provides a water-based operation platform suitable for static load testing of pile foundations in fishery-solar complementary projects. This platform not only has a large working space, which can meet the load-bearing capacity requirements of water-based static load testing in fishery-solar complementary projects, but also has a simple structure, is easy to assemble, can save workload and working time, has lower cost, is easy to transport on land, and saves costs.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A floating work platform suitable for static load testing of pile foundations in a solar-fishery integrated project includes:

[0008] Precast grid flooring consists of several precast grid flooring panels joined together at the joints using bolts and nuts to form a load-bearing platform;

[0009] Prefabricated floating components are installed on the bottom edge of the load-bearing platform using bolted connections.

[0010] Precast mesh guardrails, multiple precast mesh guardrails are connected end to end to the perimeter of the load-bearing platform, and all can be detachably connected to the precast floating body components;

[0011] The helical propulsion component is installed at the middle of one end of the load-bearing platform to provide forward propulsion.

[0012] As a further optional design of this technical solution, the prefabricated grid floor includes a steel grating, and the mating edges of the steel grating are provided with connecting lugs that cooperate with bolt and nut connectors.

[0013] As a further optional design of this technical solution, the prefabricated floating body component includes multiple floating boxes evenly arranged around the load-bearing platform;

[0014] Each pontoon includes a floating box body and a first recessed mounting hole and a second recessed mounting hole formed on the floating box body. The first recessed mounting hole is inserted into the prefabricated mesh guardrail, and the second recessed mounting hole is connected to the bolt connector.

[0015] As a further optional design of this technical solution, the prefabricated grid fence includes a first grid fence and a second grid fence that are continuously and alternately distributed;

[0016] The first grid fence includes a first fence mesh, and both ends of the first fence mesh have an upper insertion shaft and a lower insertion shaft, the lower insertion shaft being adapted to a first recessed mounting hole;

[0017] The second grid fence includes a second fence mesh, both ends of which have plug-in sleeves adapted to the upper plug-in shaft.

[0018] As a further optional design of this technical solution, the helical propulsion component includes a propeller thruster installed at the midpoint of the width direction of the load-bearing platform.

[0050] In this embodiment, the prefabricated floating body component 2 is arranged only on the outer periphery of the supporting platform in a discontinuous manner, and adopts a prefabricated grid floor 1 and prefabricated grid guardrail 3 in a grid form. These features achieve the platform's lightweight design, lower cost, and facilitate land transportation, thus saving costs.

[0051] In this embodiment, the prefabricated grid floor 1, prefabricated floating body component 2, prefabricated grid guardrail and spiral propulsion component are all modular and simplified structures, and the assembly method is simple and quick plug-in and bolt and nut connection, so it is easy to assemble, can save workload and working time, and has a large working space, which can meet the load-bearing capacity requirements of the static load test water operation of the fishery-solar complementary project.

[0052] Please refer to Figure 4 The prefabricated grid floor 1 in this embodiment may include a steel grating 11, and the mating edge of the steel grating 11 is provided with a connecting ear plate 111 that cooperates with the bolt and nut connector 12.

[0053] In this embodiment, the connection method of the load-bearing platform and the connection method between the load-bearing platform and the floating box 21 are as follows: the steel grating 11 is connected by multiple connectors, the floating box 21 has an internal thread that matches the fixing bolt, and the first recessed mounting hole 211-1 on the floating box 21 is screwed in, and the steel grating 11 is located between the fixing bolt and the floating box 21.

[0054] More specifically, two steel grating plates 11 can be used, and they can be connected at the connecting lugs 111 by four bolts and nuts 12 to form a load-bearing platform. Furthermore, four pontoons 21 are arranged at the four vertices of the load-bearing platform. The load-bearing platform is connected to each pontoon 21 by inserting fixing bolts into the first recessed mounting holes 211-1 to maintain a uniform load distribution.

[0055] Please refer to Figure 5 In this embodiment, the bolt and nut connector 12 is a bolt and nut assembly. In use, the bolt passes through the annular screw hole at the upper connecting ear plate 111 of the steel grating plate 11 and is screwed into the nut.

Figure 6 Each pontoon 21 includes a floating box body 211 and a first recessed mounting hole 211-1 and a second recessed mounting hole 211-2 opened on the floating box body 211. The first recessed mounting hole 211-1 is inserted into the prefabricated grid guardrail 3, and the second recessed mounting hole 211-2 is connected to the bolt connector 22.

[0057] Please refer to Figure 7In this embodiment, the bolt connector 22 can be a fixing bolt. In use, the steel grating 11 has a circular hole of appropriate diameter at the fixing bolt mounting location. The fixing bolt passes through the circular hole and is screwed into the first recessed mounting on the float 21.

[0058] More specifically, the first recessed mounting hole 211-1 can be opened at the center of the float 21. It is understood that the first recessed mounting hole 211-1 has an internal thread structure for connecting and fixing bolts.

[0059] More specifically, the second recessed mounting hole 211-2 is located at one corner of the outer side of the load-bearing platform and is used to insert the first mesh guardrail 31. Typically, the diameter of the second recessed mounting hole 211-2 is smaller than the diameter of the first recessed mounting hole 211-1.

[0060] In this embodiment, the prefabricated grid guardrail 3 may include a first grid guardrail 31 and a second grid guardrail 32 that are continuously and alternately distributed. The installation method of the first grid guardrail 31, the second grid guardrail 32 and the pontoon 21 is as follows: the first grid guardrail 31 has steel bars extending from both sides, the lower part of the steel bars is used to insert into the second recessed mounting hole 211-2 on the pontoon 21, and the upper part of the steel bars is used to insert into the two cylindrical parts on both sides of the second grid guardrail 32.

[0061] For example, refer to Figure 8 The first mesh guardrail 31 in this embodiment may include a first guardrail mesh 311. Both ends of the first guardrail mesh 311 have an upper insertion shaft 3111 and a lower insertion shaft 3112. The lower insertion shaft 3112 is adapted to the first recessed mounting hole 211-1.

The part of the steel bar protruding from the upper end of the first guardrail mesh 311 forms the upper insertion shaft 3111, and the part of the steel bar protruding from the lower end of the first guardrail mesh 311 forms the lower insertion shaft 3112.

[0063] Please refer to Figure 9 and Figure 10 For example, the second mesh guardrail 32 in this embodiment may include a second guardrail mesh 321, and both ends of the second guardrail mesh 321 have plug sleeves 3211 adapted to the upper plug shaft 3111.

[0064] More specifically, the middle part of the second grid fence 32 is the second fence net 321, and the upper parts of both ends of the second grid fence 32 are hollow cylinders (i.e., plug-in sleeves 3211). During assembly, the first fence net 311 is inserted into the hollow cylinder from below, and finally aligned with the lower part of the second fence net 321 to form a continuous enclosure.

[0065] In practice, the lengths of the first grid guardrail 31 and the second grid guardrail 32 are adapted to the load-bearing platform composed of two steel grating plates 11 for installation. The first guardrail mesh 311 of the first grid guardrail 31 is fixedly connected to the steel bars on both sides by welding. The second recessed mounting hole 211-2 of the float box 21 is adapted to the diameter of the steel bar for securely fixing the first grid guardrail 31. The second guardrail mesh 321 is rigidly connected to the hollow cylinders on both sides. The diameter of the hollow cylinders must be adapted to the diameter of the steel bars of the first grid guardrail 31 for secure installation.

[0066] In this embodiment, refer to Figure 1 The helical propulsion component 4 may include a propeller 41 installed at the midpoint of the width direction of the load-bearing platform.

[0067] More specifically, refer to Figure 3 In this embodiment, the propeller thruster 41 can be fixed at the midpoint of the width direction of the load-bearing platform composed of two steel grating plates 11 by means of its own mounting device.
