Description

Technical Field

[0001] The present invention relates to the technical field of marine photovoltaic engineering, and particularly to a prefabricated and movable installation platform structure for a beach photovoltaic support assembly. Background Art

[0002] Most large-scale marine photovoltaic power generation projects in China are located in coastal areas and tidal flats. The photovoltaic construction mainly adopts the "prestressed concrete pipe pile + steel bracket" scheme. The construction devices of the pile foundation fixed-type offshore photovoltaic project are numerous, and the construction site required is large. A temporary installation platform needs to be used for the flow or cross construction of the support assembly. The installation platform is a basic and controlling part in the whole offshore photovoltaic construction, affecting the construction of the whole photovoltaic project. As a special type of bridge, there is no systematic research on the design structure of the trestle at home and abroad, and there is no unified design specification to follow. Therefore, it is generally designed by referring to some similar engineering design and construction specifications and combining experience, which has great uncertainty and potential safety hazards, and is very disadvantageous in engineering construction.

[0003] In the actual construction of the trestle, due to the different service functions of different trestles, the loads and environmental conditions are also different. The pulley-type trestle platform is one type of trestle. The traditional pulley-type trestle platform is not only difficult to assemble and disassemble, but also when the steel platform in the structure is transported, the direction is extremely easy to deviate greatly, resulting in the platform being stuck and unable to move, and even the structure being unstable. In the actual construction process, the method of manually prying to restore the steel platform is time-consuming and laborious, which greatly delays the construction period of the offshore photovoltaic power generation project and increases unnecessary construction costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a prefabricated and movable installation platform structure for a beach photovoltaic support assembly, which can effectively overcome the problems of difficult assembly, disassembly construction and transportation of the traditional pulley-type trestle platform in view of the deficiencies of the existing technology.

[0005] The above object of the present invention is achieved by the following technical solutions: A prefabricated and movable installation platform structure for a beach photovoltaic support assembly, characterized in that the novel movable installation platform structure for a beach photovoltaic support assembly includes a steel trestle, a track structure and a steel platform; the steel trestle is composed of multiple unit modules, each unit module is composed of a single-pile foundation and a steel frame structure, the steel frame structure is assembled on the single-pile foundations on both sides, the track structure is assembled on the steel trestle and fixed by bolts to serve as the support for the upper steel platform, and the steel platform is assembled on the track structure and can be directionally moved to different positions along the steel rails.

[0006] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these further technical solutions in combination: The single pile foundation is a steel pipe pile, on which a clamp is installed. The clamp is made of stainless steel and is connected to the steel frame structure.

[0007] The track structure consists of a track rail wheel mechanism and a guide mechanism. The rail wheel mechanism is used to support the upper steel platform. The guide mechanism is made of stainless steel and has guide steel rollers installed on its sides. The guide mechanism is arranged in a row on both sides of the steel trestle corresponding to the two sides of the steel platform, so as to limit the moving direction of the upper steel platform and ensure that the steel platform does not deviate too much during the movement.

[0008] The steel platform is composed of a platform frame main beam and a platform secondary beam. Skirting line buckles are arranged on both sides of the steel platform. The platform secondary beam is used to reinforce the platform frame main beam. The platform frame main beam and the platform secondary beam are connected together by welding to jointly bear the upper load. The skirting line buckles are used to fix the laid steel springboard.

[0009] An upper and lower layer of hoops are arranged on the single pile foundation, the steel frame structure comprises a main body and a diagonal brace below, and the upper and lower layer of hoops (6) are respectively connected to the main body of the steel frame structure and the diagonal brace below by bolts.

[0010] Due to the adoption of the technical solution of the present invention, the present invention has the following beneficial technical effects: 1. The structure adopts prefabricated components. The steel trestle, track structure and steel platform are all modular assembly parts, which can be quickly assembled and disassembled, improving the efficiency of offshore operations (when the tide is high on the tidal flats). It is also suitable for different construction conditions, has strong engineering versatility and a safe and stable structure.

[0011] 2. The steel platform in the structure is assembled on the track structure and can be moved along the rail to different positions for alternate construction, saving the overall steel required to build the construction platform.

[0012] 3. The clamp in the structure is installed on the monopile foundation, which can effectively increase the load-bearing area of the monopile foundation used in the tidal flat area, thereby effectively fixing the steel frame structure and effectively preventing the steel trestle from being submerged by the tide during construction, which can increase the operating area and stability of the offshore photovoltaic construction platform.

[0013] 4. The guide device in the structure is equipped with guide rail wheels, which can effectively limit the moving direction of the steel platform and increase the moving speed, thereby preventing the steel platform from getting stuck due to excessive offset during movement, reducing the working hours spent on restoring the moving direction of the steel platform and reducing the amount of construction work.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] As Figure 1 , 2 , shown in 6, this embodiment is an assembled and movable installation platform structure for a beach photovoltaic support assembly, including a steel trestle 1, a track structure 2, and a steel platform 3. The steel trestle 1 is arranged in the construction beach area, set according to the running route of the steel platform, and passes near the designed position of the photovoltaic support assembly. The steel trestle 1 is composed of multiple unit modules, and each unit module is composed of a single-pile foundation 4 and a steel frame structure 5. The steel frame structure 5 can use a steel beam as the main structure and can be prefabricated in a workshop as an installation module and assembled on the single-pile foundations 4 on both sides as the foundation of the entire platform structure. The track structure 2 is assembled on the steel trestle 1 and fixed by screws as the support for the upper steel platform 3. The steel platform 3 is assembled on the track structure 2 and can be directionally moved along the steel rail to different positions.

[0017] As Figure 3 shown, the single-pile foundation 4 is a steel pipe pile, and a hoop 6 is installed on the pile. The hoop 6 is made of stainless steel and is connected to the steel frame structure 5. Among them, two layers of hoops 6 are arranged on the single-pile foundation 4. The steel frame structure 5 includes its main body and the lower diagonal brace 51. The diagonal brace 51 is rotatably installed on the main body of the steel frame structure 5, and the two layers of hoops 6 are respectively connected to the main body of the steel frame structure 5 and the lower diagonal brace 51 by bolts.

[0018] As Figure 4As shown, the track structure 2 is composed of a rail wheel mechanism 7 and a guide mechanism. The rail wheel mechanism 7 is arranged in a row on both sides and in the middle of the steel trestle 1 to support the upper steel platform 3. The guide mechanism is located on the outer sides of the two sides of the steel trestle and includes a mounting seat 8 made of stainless steel. The mounting seat 8 is installed with a guide steel roller 9 on the side facing the steel platform 3. The guide mechanism is arranged in a row on both sides of the steel trestle 1 to limit the moving direction of the upper steel platform 3 to ensure that the steel platform 3 does not deviate too much during the movement. The steel platform 3 can cooperate with the guide steel roller 9 through the side of the steel rail 13 below it or the main beam part of the platform frame located below the buckle. The rail wheel mechanism 7 includes a roller support 71, and a rail support steel roller 72 is installed on the roller support 71. The rail wheel mechanism 7 and the guide mechanism can be prefabricated as an installation module. During on-site construction, the roller support 71 and the mounting seat 8 can be connected to the steel frame structure 5 by bolts.

[0019] like Figure 4 , 5 As shown, the steel platform 3 is composed of a platform frame main beam 10 and a platform secondary beam 11, which can be prefabricated as an installation module, or for the convenience of transportation, a number of sub-modules can be prefabricated first and connected to form a steel platform 3 on site. Skirting buckles 12 are set on both sides of the steel platform 3, and a steel rail 13 is set at the bottom of the platform frame main beam 10. The steel rail 13 is clamped on the supporting steel roller 72 below it. The platform secondary beam 11 is used to reinforce the platform frame main beam 10. The platform frame main beam 10 and the platform secondary beam 11 are connected together by welding to jointly bear the upper load. The skirting buckle 12 is used to fix the laid steel springboard.

[0020] Among them, when the steel platform 3 deviates during movement, the edge of the steel platform 3 will touch the guide steel roller 9 on the guide mechanism. During the rolling process, the guide steel roller 9 will apply a force in the opposite direction of the deviation to the moving steel platform 3, thereby continuously adjusting the steel platform 3 back to the preset moving direction, so that the steel platform 3 maintains a relatively fast moving state and prevents it from getting stuck due to excessive deviation.

[0021] It can be seen from the embodiments of the present invention that in the present invention, the steel trestle 1 is composed of multiple independent units, which are interconnected through the design route, which is convenient for flexible arrangement, convenient for disassembly and assembly, and cost saving; and the steel rails are set on the steel platform 3, so that under the load required for installing the photovoltaic bracket, it can not only operate reliably, but also realize the design route more easily, and can be effectively applied to the tidal flat area. After the project is completed, it is also convenient for storage and placement for reuse in the next project. In addition, the present invention uses upper and lower layers of clamps 6 to connect and install the steel frame structure 5, which is faster to install on the basis of meeting the structural strength.

[0022] Depend on Figures 7 - 10It can be seen that the calculation result of the structural stability of the present invention is good, and the structure is safe and stable under the action of engineering loads. Figure 7 The shear force and bending moment distribution response of the cross beam and longitudinal beam in the steel platform of the structure of the present invention under the engineering load condition is shown. It can be seen from the figure that the shear force and bending moment inside the installation platform under the engineering load condition meet the design requirements; Figure 8 and 9 The stress distribution response of the steel platform and the steel trestle in the installation platform of the structure of the present invention under engineering load conditions is shown. It can be seen from the figure that the maximum stress inside the installation platform under engineering load conditions is much lower than the steel material strength of 235MPa, and the platform structure is safe and stable; Figure 10 The vertical displacement deformation distribution response of the installation platform of the structure of the present invention under engineering load conditions is demonstrated. As can be seen from the figure, the vertical displacement deformation of the installation platform under engineering load conditions meets the design requirements.

[0023] In summary, the structure provided in the present application is used for the installation of photovoltaic brackets in tidal flat areas. It has the characteristics of prefabricated modular assembly, is relatively convenient to construct, has a safe and stable structure, and the steel platform can move in a directional manner along the steel rails. It can also prevent the steel platform from getting stuck due to excessive offset during the construction and movement process, and reduce the working hours spent on restoring the moving direction of the steel platform by manual prying, thereby effectively reducing the workload and improving the construction efficiency of the tidal flat photovoltaic platform.
