Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power station construction, in particular to an offshore photovoltaic integrated construction platform. Background Art

[0002] Currently, most existing offshore photovoltaic power stations are pile-based fixed photovoltaic power stations, which are mainly composed of several piles set in the mudflats and photovoltaic panels installed on top of the piles. Due to the high and low tides on mudflats, traditional land-based piling equipment is often not directly applicable to mudflat piling. To solve the above problems, a series of mudflat piling equipment has emerged in the existing technology, but there are still some problems in actual use, such as:

[0003] 1) The utility model patent with publication number CN218580644U discloses an amphibious tidal flat photovoltaic piling equipment. The adjustment of the position of the pile frame relies on the steering of the pontoon-type crawler, while the double pontoon structure relies on the speed difference or forward and reverse rotation of the left and right crawlers to steer. The turning radius is large and the steering is not flexible, making it difficult to quickly and accurately position the pile frame, affecting construction efficiency; the support area of ​​the double pontoon is small, and the piling boat has poor stability in the water; the height of the machine base is fixed, which is not suitable for construction during high tide, affecting the construction period.

[0004] 2) The utility model patent with publication number CN219568805U discloses an offshore photovoltaic multifunctional positioning platform, which is not suitable for construction in shallow water areas, affecting the construction period; the center of gravity of the mounting frame is high, affecting its stability in water.

[0005] 3) The utility model patent with publication number CN219862793U discloses a piling device for prefabricated piles on water for use in salt-light complementary photovoltaic power generation. The device adopts a pile head piling method and is clamped at the head of a PHC pipe pile for piling. The length of the mechanical arm needs to be longer than the length of the PHC pipe pile, which requires the use of an extension arm, increasing manufacturing costs. The center of gravity of the extension arm is high, affecting its stability in the water. It is not suitable for construction during high tide, which affects the construction period. The support area of ​​the double pontoon is small, and the piling boat has poor stability in the water. The double pontoon structure relies on the speed difference or forward and reverse rotation of the left and right tracks for steering, resulting in a large turning radius and inflexible steering, which affects construction efficiency.

[0006] In addition, the above-mentioned mudflat piling equipment needs to be equipped with water transportation equipment for prefabricated piles and photovoltaic panels when in use, which also increases construction costs. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the prior art and provide an offshore photovoltaic integrated construction platform that can complete piling in the mudflats to ensure uninterrupted construction, and has a transportation function and high construction efficiency.

[0008] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0009] The offshore photovoltaic integrated construction platform includes two pontoon crawler assemblies arranged in sequence from front to back;

[0010] Each of the pontoon crawler assemblies comprises a horizontally arranged connecting frame, pontoon crawlers arranged at the left and right ends of the connecting frame, and a height-adjustable support platform arranged above the connecting frame, wherein a support frame is provided on the top of the pontoon of each pontoon crawler, and a height adjustment device is provided between the support frame and the height-adjustable support platform;

[0011] A first mechanical arm is provided at one end of the height-adjustable support platform on the rear pontoon crawler assembly, one end of the first mechanical arm is rotatably connected to the height-adjustable support platform, and the other end is provided with a side-clamping pile driver, and a first driving mechanism for driving the first mechanical arm to rotate around a vertical axis is provided on the height-adjustable support platform;

[0012] Oil cylinders are provided at both left and right ends between the two pontoon track assemblies. One end of the oil cylinder is hinged to the front pontoon, and the other end is hinged to the rear pontoon.

[0013] Preferably, the support frame includes a guide column and a U-shaped frame fixed to the bottom of the guide column, a guide hole adapted to the guide column is provided on the height-adjustable support platform, the U-shaped frame is connected to the buoyancy box, and the buoyancy box is located inside the U-shaped frame.

[0014] Preferably, a second robotic arm is provided on the end of the height-adjustable support platform on the rear pontoon track assembly away from the first robotic arm, one end of the second robotic arm is rotatably connected to the height-adjustable support platform, and the other end is provided with a photovoltaic panel clamping claw, and a second driving mechanism is provided on the height-adjustable support platform for driving the second robotic arm to rotate around a vertical axis.

[0015] Preferably, the offshore photovoltaic integrated construction platform also includes a precast pile transport warehouse, a support shaft is provided at one end of the bottom of the precast pile transport warehouse, and a stepped shaft is provided at the other end. The precast pile transport warehouse is rotatably connected to one of the height-adjustable support platforms through the support shaft, and an arc groove adapted to the stepped shaft is provided on the top of the other height-adjustable support platform, and the cross-section of the arc groove is an inverted T-shape.

[0016] Preferably, photovoltaic panel transport bins are provided on both the left and right sides of the precast pile transport bin.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The height of the height-adjustable support platform of the present invention is adjustable. The height of the height-adjustable support platform can be adjusted by the height-adjusting device. Both the robotic arm and the PHC piles can be placed on the height-adjustable support platform. During construction, it is not affected by high tide and low tide, and the continuity of construction can be guaranteed.

[0019] 2. The height-adjustable support platform of this utility model can be used to transport precast piles. Precast piles can be placed on the two height-adjustable support platforms, front and rear. During high and low tides twice a day, the ability of pile transport vessels to dock is limited, which affects pile transport efficiency.

[0031] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0032] Currently, most pile-based offshore photovoltaic stations are located in the intertidal zone, within 5 kilometers of the shore. They are significantly affected by tides, which cause varying water depths (tidal range of 2 to 5 meters). The tide type is irregular semi-diurnal, meaning there are two high tides and two low tides in a single solar day, but the heights of the two adjacent high and low tides are unequal, and the high and low tides are also unequal. This leads to certain limitations in the use of existing water piling equipment:

[0033] 1) During the construction process, due to the influence of high and low tides, the existing offshore piling equipment and pile transport equipment need to be frequently stopped, which delays the construction period;

[0034] 2) During low tide, when the water depth is not suitable for operation (water depth is less than 1 meter), the piling vessel (such as the existing utility model patent with publication number CN219568805U) should withdraw from the construction site and move to a nearby channel or deep water area to wait for the tide, and then return to the site for operation after the next high tide cycle;

[0035] 3) During high tide, as the water depth increases (water depth exceeds 2 meters), amphibious piling equipment (such as existing utility model patents with publication numbers CN218580644U and CN219862793U) must be removed from the site and transferred to a temporary dock or nearby shore for waiting;

[0036] 4) PHC pile transportation mainly relies on small pile transport vessels, which can transport 4 to 6 piles at a time. This has a low transportation efficiency. Especially during low tide, the pile transport vessels cannot dock to load, which is also a key issue that restricts construction efficiency.

[0037] In response to the above problems, the present invention adopts two front and rear pontoon track assemblies 1, a height-adjustable support platform 13, and a side-clamp pile driver 3 to complete piling in the mudflat, ensuring uninterrupted construction, and has a transportation function and high construction efficiency.

[0038] Example: As shown in the attached Figure 1-7 As shown, the utility model is an offshore photovoltaic integrated construction platform, including two pontoon track assemblies 1 arranged in sequence from front to back, and oil cylinders 4 are provided at both ends of the left and right sides between the two pontoon track assemblies 1. One end of the oil cylinder 4 is hinged to the front pontoon, and the other end is hinged to the rear pontoon.

[0039] The reason for using two pontoon track assemblies 1 is that, on the one hand, when a single pontoon track assembly 1 is used, in order to transport the PHC pipe piles 7, the pontoon track assembly 1 needs to be long enough, which requires a high degree of rigidity of the pontoon track assembly 1, otherwise the pontoon track assembly 1 may break from the middle; on the other hand, when a single pontoon track assembly 1 is used, its turning radius is large, while the present application uses two front and rear pontoon track assemblies 1, and flexibly connects the front and rear pontoon track assemblies 1 through the cylinder 4. By adjusting the rotation speed of the left and right pontoon tracks 12 and combining the extension and contraction of the two cylinders 4, the turning radius of the present invention can be reduced, turning is convenient, and it is convenient to adjust the pile driving position and transportation route.

[0040] As attached Figure 4 As shown, each of the pontoon crawler assemblies 1 includes a horizontally arranged connecting frame 11, a pontoon crawler 12 arranged at the left and right ends of the connecting frame 11, and a height-adjustable support platform 13 arranged above the connecting frame 11. The pontoon crawler 12 consists of a pontoon and a crawler mechanism installed on the pontoon. A pontoon is welded at each end of the connecting frame 11, wherein a support frame 14 is welded to the top of the pontoon of each pontoon crawler 12, and a height adjustment device 15 is provided between the support frame 14 and the height-adjustable support platform 13.

[0041] When the tide is high or the water enters a deep water area, the height-adjustable support platform 13 is lifted upwards by utilizing the height-adjusting device 15 , and vice versa, the height of the height-adjustable support platform 13 is lowered.

[0042] The front and rear pontoon track assemblies 1 of the present invention each have two pontoons, so that the bottom support area of ​​the present invention is large and the stability in water is better.

[0043] The two front and rear height-adjustable support platforms 13 can be used to install the engine, hydraulic actuator, radiator tank, diesel tank, hydraulic oil tank, cab, two mechanical arms with rotating bases, etc., and can also be used as a storage area for PHC piles and photovoltaic modules. The PHC piles 7 can also be directly placed on the two front and rear height-adjustable support platforms 13 (such as Figure 1 shown).

[0044] Preferably, in order to ensure the stability of PHC pile transportation, Figure 6-7 As shown, the offshore photovoltaic integrated construction platform also includes a precast pile transport bin 6, one end of the bottom of the precast pile transport bin 6 is welded with a support shaft 61, and the other end is provided with a stepped shaft 62. The precast pile transport bin 6 is rotatably connected to one of the height-adjustable support platforms 13 through the support shaft 61, and an arc groove adapted to the stepped shaft 62 is provided on the top of the other height-adjustable support platform 13, and the cross-section of the arc groove is an inverted T-shape. When the oil cylinder 4 is extended and retracted, the front and rear height-adjustable support platforms 13 change from a parallel state to a non-parallel state, and the stepped shaft 62 slides a certain distance in the arc groove accordingly, so that the precast pile transport bin 6 can always be fixed on the front and rear height-adjustable support platforms 13, thereby ensuring the stability of transportation.

[0045] Furthermore, photovoltaic panel transport compartments 63 are provided on both the left and right sides of the precast pile transport compartment 6 .

[0046] Preferably, to ensure the stability of the overall structure, the support frame 14 includes a guide column 141 and a U-shaped frame 142 welded to the bottom of the guide column 141. The height-adjustable support platform 13 is provided with a guide hole adapted for the guide column 141. The U-shaped frame 142 is welded to the upper portion of the pontoon, which is located inside the U-shaped frame 142. The height-adjustable support platform 13 is plate-shaped, and the height adjustment device 15 can be a hydraulic cylinder. The cylinder body of the hydraulic cylinder is bolted to the height-adjustable support platform 13. A flange is welded to the protruding end of the hydraulic cylinder piston rod, and the flange is bolted to the top of the U-shaped frame 142.

[0047] A first mechanical arm 2 is provided at one end of the height-adjustable support platform 13 on the rear pontoon crawler assembly 1. One end of the first mechanical arm 2 is rotatably connected to the height-adjustable support platform 13, and a side-clamping pile driver 3 is provided at the other end. A first driving mechanism 21 for driving the first mechanical arm 2 to rotate around a vertical axis is provided on the height-adjustable support platform 13. The side-clamping pile driver 3 can grasp the middle position of the PHC pipe pile 7. The side-clamping pile driver 3 is provided with a Beidou positioning system. The machine 3 also has the function of a hydraulic vibratory hammer. In the storage area of ​​the PHC pile 7, it grabs the middle position of the PHC pile. The side-clamp pile driver 3 rotates the PHC pile 7 from a horizontal state to a vertical state. The first mechanical arm 2 rotates around the axis of the rotating base to the vicinity of the piling position behind the equipment. With the assistance of Beidou positioning, the side-clamp pile driver 3 is accurately moved to the accurate piling position. The hydraulic vibratory hammer starts working, and the PHC pile 7 is subjected to high-frequency impact on the underwater soil to complete the water piling process.

[0048] The utility model eliminates the need for a fixed pile frame and diesel pile hammer, lowers the center of gravity of the equipment, facilitates rapid and accurate positioning, and improves construction efficiency. It eliminates the need for an extended arm and pile head type pile driver, reduces manufacturing costs, lowers the center of gravity of the equipment, and improves construction efficiency.

[0049] Preferably, a second robotic arm 5 is provided on the end of the height-adjustable support platform 13 on the rear pontoon track assembly 1 away from the first robotic arm 2, one end of the second robotic arm 5 is rotatably connected to the height-adjustable support platform 13, and the other end is provided with a photovoltaic panel clamping claw, and a second driving mechanism 22 is provided on the height-adjustable support platform 13 for driving the second robotic arm 5 to rotate around a vertical axis.

[0050] The second manipulator arm 5 and the first manipulator arm 2 can both be existing multi-degree-of-freedom manipulator arms. The first drive mechanism 21 and the second drive mechanism 22 can both be existing hydraulic excavator slewing mechanisms, which are composed of a slewing bearing, a slewing reducer, a slewing brake, and a slewing hydraulic system.

[0051] The side-clamping pile driver 3 can use the existing side-clamping pile drivers on the market, or the side-clamping pile driving equipment disclosed in existing patents, such as: a side-clamping vibratory hammer (CN106193040B), a single-side clamping pile driving device (CN211922617U), a side-clamping center vibrating hydraulic hammer (CN210827474U), a side-clamping vibratory hammer (CN207619983U), a side-clamping hydraulic vibratory hammer (CN211849426U), and an angle adjustment mechanism for a side-clamping vibratory hammer (CN205822189U).

[0052] The existing pile head hydraulic vibratory hammer is clamped at the head of the PHC pipe pile. The length of the mechanical arm must be longer than the length of the PHC pipe pile, which requires the use of an extension arm and increases manufacturing costs. The center of gravity of the extension arm is high, the stability of construction in water is reduced, and the construction efficiency is also reduced. The utility model adopts a side clamping pile driver 3 (with a hydraulic vibratory hammer) that only clamps the middle of the PHC pipe pile 7. There is no need to install an extension arm (saving manufacturing costs, lowering the center of gravity of the equipment, and improving the stability of the equipment in water) to clamp the pile head of the PHC pipe pile. It also saves labor compared to the fixed pile frame solution of the water pile driving ship. It can work uninterruptedly 24 hours a day, and is not affected by high and low tides, nor by wind direction and water flow. In order to ensure the efficiency of construction operations and the accuracy of pile spacing, Beidou positioning devices can also be installed on the two mechanical arms, especially at night, so that normal construction can be carried out, which greatly improves construction efficiency.
