Description

Technical Field

[0001] This utility model relates to the technical field of offshore photovoltaic power generation equipment, and specifically to a construction device for an offshore photovoltaic power generation unit. Background Technology

[0002] With the continuous advancement of global energy structure transformation and renewable energy development, offshore photovoltaic power generation, as a new type of clean energy utilization method, is gradually becoming an important development direction in the photovoltaic power generation field due to its advantages such as not occupying land resources and high power generation efficiency. Offshore photovoltaic power generation systems are usually composed of photovoltaic piles, photovoltaic supports, and photovoltaic modules. Among them, the installation quality of photovoltaic piles and photovoltaic supports directly affects the stability and service life of the entire power generation system.

[0003] Due to the significant risks and high costs associated with construction / installation at sea, small-module photovoltaic panel supports are gradually being replaced by large-module photovoltaic panel supports. Large-module photovoltaic panel supports consist of a main support body and four legs. First, four photovoltaic piles need to be driven into their corresponding positions, and then the four legs on the support are installed onto the four photovoltaic piles. However, since the photovoltaic panel supports are assembled on land, the matching precision between the four legs and the four photovoltaic piles is required to be high, that is, the positioning accuracy of the four photovoltaic piles is required to be high.

[0004] In existing technologies, photovoltaic (PV) piles require positioning before installation. This generally includes two positioning modes: single-pile positioning and four-pile synchronous positioning. Single-pile positioning involves a single-pile, single-stage installation, relying on a pile gripper and a vibratory hammer driven by a crane vessel. This results in significant relative deviations after installation, making it difficult to guarantee positioning accuracy among multiple PV piles. Four-pile synchronous positioning primarily uses a four-pile synchronous positioning device, minimizing relative deviations. However, this device is bulky and heavy, making movement to the next work position time-consuming and labor-intensive. More importantly, the synchronous positioning device itself is difficult to position. Field observations indicate that the movement and positioning time of the synchronous positioning device accounts for over 80% of the entire construction cycle, severely impacting construction efficiency.

[0005] Furthermore, in existing technologies, the installation of photovoltaic (PV) brackets typically requires multiple adjustments to achieve precise alignment with the PV piles, increasing construction difficulty and time costs. Due to the complex marine construction environment and significant impact from wind and waves, traditional construction methods struggle to guarantee the installation accuracy of the PV piles and brackets, thereby affecting the stability and power generation efficiency of the entire PV power generation unit. Utility Model Content

[0006] This utility model addresses the aforementioned problems and aims to provide a construction device for offshore photovoltaic power generation units, enabling integrated construction to reduce relative construction deviations of photovoltaic piles and improve installation efficiency.

[0007] To achieve the above objectives, this utility model provides a construction device for an offshore photovoltaic power generation unit, comprising:

[0008] hull;

[0009] The positioning mechanism includes multiple positioning units spaced apart on both sides of the hull, each of which can provide pile positioning for a photovoltaic pile.

[0010] The lifting and translating mechanism includes a base frame, a top frame, and a lifting unit. The base frame is movably mounted on the hull, and the top frame can be used to place photovoltaic brackets and is mounted on the base frame in a way that allows it to be raised and lowered via the lifting unit.

[0011] According to the above-described construction device for an offshore photovoltaic power generation unit, the lifting and translation mechanism further includes a first guide rail, which is arranged on the hull along the length of the hull, and the base frame is movably mounted on the first guide rail.

[0012] According to the above-described construction device for an offshore photovoltaic power generation unit, the lifting unit includes a lifting cylinder, which is located between the base frame and the top frame, and the piston rod of the lifting cylinder is connected to the bottom of the top frame.

[0013] According to the above-described construction device for an offshore photovoltaic power generation unit, four lifting cylinders are provided, and the four lifting cylinders are respectively installed at the four corners of the top of the base frame, and the piston rods of the four lifting cylinders can be connected to the four corners of the bottom of the base frame.

[0014] According to the above-described construction device for a marine photovoltaic power generation unit, there are four positioning units, which are symmetrically arranged in pairs at the front and rear ends of both sides of the hull.

[0015] According to the above-described construction device for a marine photovoltaic power generation unit, each positioning unit includes two rotating shafts erected on the hull, two first rotating platforms, and two first limiting half-rings. The two first rotating platforms are respectively installed on the two rotating shafts and can rotate with the rotating shafts. The two first limiting half-rings are respectively installed on opposite sides of the two first rotating platforms.

[0016] The two rotating shafts rotate synchronously in opposite directions, which can drive one end of the two first limiting half rings to move toward each other or away from each other, so that the two first limiting half rings are in an open or closed state. When the two first limiting half rings are in a closed state, the two first limiting half rings together form a first positioning hole for surrounding the photovoltaic pile.

[0017] According to the above-described construction device for an offshore photovoltaic power generation unit, two first limiting semi-rings are respectively movably mounted on one side of the first rotating platform via a first adjusting cylinder. The first adjusting cylinder is fixed on the first rotating platform, and the piston rod of the first adjusting cylinder is connected to the first limiting semi-ring.

[0018] According to the above-described construction device for an offshore photovoltaic power generation unit, the positioning unit further includes two second rotating platforms and two second limiting semi-rings. The two first rotating platforms are respectively installed on the upper part of the two rotating shafts, and the two second rotating platforms are respectively installed on the lower part of the two rotating shafts. The first rotating platforms and the second rotating platforms installed on the same rotating shaft are vertically aligned.

[0019] The two second limiting semi-rings are respectively movably set on one side of the second rotating platform by a second adjusting oil cylinder, and the two second limiting semi-rings can be closed to form a second positioning hole for surrounding the photovoltaic pile, the second positioning hole being located directly below the first positioning hole.

[0020] According to the above-described construction device for an offshore photovoltaic power generation unit, both the upper part of the first positioning hole and the second positioning hole are provided with inclined guide surfaces.

[0021] The above-described construction device for offshore photovoltaic power generation panels also includes a hoisting mechanism. The hoisting mechanism includes a tower and a boom. The tower is fixed to the hull, and the boom is movably mounted on the top of the tower and can hoist the photovoltaic pile to the positioning unit.

[0022] And / or, it also includes a pile driving mechanism installed on the hull.

[0023] This utility model has the following beneficial effects:

[0024] 1. The lifting and translation mechanism can drive the photovoltaic support to move on the hull. It has better stability when installing large module photovoltaic supports and can accurately adjust the position of the photovoltaic support so that its outriggers are accurately aligned with the center of the photovoltaic pile. This facilitates the installation of large-volume photovoltaic supports and improves the installation efficiency of photovoltaic supports.

[0025] 2. By setting multiple positioning units on both sides of the hull, each positioning unit is used to provide positioning for a photovoltaic pile, and multiple photovoltaic piles can be precisely positioned and constructed at the same time. Compared with the single-pile single-time construction in the existing technology, the relative construction deviation between photovoltaic piles is greatly reduced and the construction accuracy is improved. At the same time, multiple positioning units are fixed on the hull, making the overall movement more convenient.

[0026] 3. It realizes the integrated operation of photovoltaic pile positioning construction and photovoltaic bracket installation, reduces construction links, and improves overall construction efficiency. Compared with the existing technology where the movement and positioning time of the positioning device accounts for more than 80% of the entire construction cycle, it greatly shortens the construction cycle.

[0027] 4. The positioning unit adopts a combination structure of a rotating platform and a semi-ring limiting device. It can be in the open state when not in construction. During construction, the rotation of the rotating platform makes the semi-ring limiting device form a ring structure, and the relative position of the photovoltaic pile is adjusted by the hydraulic device, thus realizing high-precision positioning of the photovoltaic pile.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] like Figure 1-3 As shown, a construction device for an offshore photovoltaic power generation unit includes a hull 100, a positioning mechanism 200, a lifting and translating mechanism 300, and a hoisting mechanism 400. The photovoltaic power generation unit includes a photovoltaic pile 500 and a photovoltaic bracket with photovoltaic panels installed. The construction device is used to first install the photovoltaic pile 500 to the corresponding position, and then install the photovoltaic bracket onto the photovoltaic pile 500.

[0039] In this embodiment, the positioning mechanism 200, the lifting and translating mechanism 300, and the hoisting mechanism 400 are integrated on the hull 100. When the hull 100 moves, the positioning mechanism 200, the lifting and translating mechanism 300, and the hoisting mechanism 400 can move synchronously, resulting in a high degree of integration. The positioning mechanism 200 is used to position multiple photovoltaic piles 500, ensuring the positioning accuracy between the multiple photovoltaic piles 500 and reducing the relative construction deviation between the multiple photovoltaic piles 500. The lifting and translating mechanism 300 is used to drive the photovoltaic bracket to move in both directions, so as to realize the photovoltaic bracket's avoidance of the photovoltaic piles 500 and the installation of the photovoltaic bracket onto multiple photovoltaic piles 500. That is, the photovoltaic pile 500 positioning construction and photovoltaic bracket installation are integrated, reducing construction links and improving overall construction efficiency. Compared with the prior art, where the movement and positioning time of the positioning device accounts for more than 80% of the entire construction cycle, the construction cycle is greatly shortened.

[0040] Among them, the hull 100 is the basic platform of the entire construction device. It is equipped with an anchoring system for positioning operations at sea. The anchoring system can ensure that the hull 100 maintains a stable position during the construction process at sea, providing a stable working platform for the subsequent positioning of the photovoltaic pile 500 and the installation of the photovoltaic bracket.

[0041] Specifically, the positioning mechanism 200 includes multiple positioning units 210 symmetrically arranged on both sides of the hull 100. Each positioning unit 210 is used to provide pile positioning for a photovoltaic pile 500 to ensure the pile driving accuracy of the photovoltaic pile 500. Multiple photovoltaic piles 500 can be hoisted sequentially to multiple positioning units 210 by the hoisting mechanism 400. The multiple positioning units 210 clamp and position the corresponding photovoltaic pile 500 respectively. After positioning, multiple photovoltaic piles 500 can be driven to ensure that their tops are at the preset elevation, which can improve the installation efficiency of the photovoltaic piles 500. At the same time, since multiple positioning units 210 move together with the hull 100, there is no need to arrange additional moving mechanisms. Their relative positions remain unchanged, which can improve the positioning accuracy between multiple photovoltaic piles 500.

[0042] Furthermore, four positioning units 210 are provided. The four positioning units 210 are symmetrically arranged in pairs at the front and rear ends of both sides of the hull 100, and can be used to simultaneously position four photovoltaic piles 500. The four photovoltaic piles 500 are positioned in a one-to-one correspondence with the four legs of the photovoltaic bracket. As long as the positioning accuracy between the four photovoltaic piles 500 is guaranteed, the accuracy of the photovoltaic bracket installation can be ensured.

[0043] Furthermore, each positioning unit 210 has the same structure, including two rotating shafts 211 erected on the hull, two first rotating platforms 212, and two first limiting semi-rings 213. The two first rotating platforms 212 are respectively fixed on the two rotating shafts 211 and can rotate with the rotating shafts 211. The two first limiting semi-rings 213 are respectively installed on opposite sides of the two first rotating platforms 212. The synchronous rotation of the two rotating shafts 211 in opposite directions can drive one end of the two first limiting semi-rings 213 to move toward or away from each other, thereby enabling the two first limiting semi-rings 212 to move toward each other. One limiting half-ring 213 is in an open or closed state. When the two first limiting half-rings 213 are in a closed state, the two first limiting half-rings 213 together form a first positioning hole for surrounding the photovoltaic pile 500. That is, the two first rotating platforms 212 can be rotated by the two rotating shafts 211. According to the rotation of the two first rotating platforms 212, the first positioning holes of different sizes can be formed, which can be applied to photovoltaic piles 500 of different diameters. Moreover, the clamping of the photovoltaic pile 500 by the two first limiting half-rings 213 can effectively ensure the driving accuracy of the photovoltaic pile 500.

[0044] Furthermore, the positioning unit 210 also includes two second rotating platforms 214 and two second limiting semi-rings 215. The two first rotating platforms 212 are respectively installed on the upper part of the two rotating shafts 211, and the two second rotating platforms 214 are respectively installed on the lower part of the two rotating shafts 211. The first rotating platforms 212 and the second rotating platforms 214 installed on the same rotating shaft 211 are vertically aligned. The two second limiting semi-rings 215 can be closed to form a second positioning hole for surrounding the photovoltaic pile 500. The second positioning hole is located directly below the first positioning hole. That is, by using the first positioning hole and the second positioning hole arranged in the vertical direction, it can be ensured that the photovoltaic pile 500 is always in a vertical state. Once it is in an inclined state, it cannot be inserted into the first positioning hole and the second positioning hole at the same time. It can not only fix the photovoltaic pile 500 more stably, but also prevent the photovoltaic pile 500 from shifting during the installation process.

[0045] Of course, in order to achieve the rotation of the two rotating shafts 211, a hydraulic cylinder or a motor can be used for driving.

[0046] Furthermore, two first limiting semi-rings 213 are movably mounted on one side of the first rotating platform 212 via a first adjusting cylinder 213b. The first adjusting cylinder 213b is fixed on the first rotating platform 212, and its piston rod is connected to the first limiting semi-ring 213. The position of the first limiting semi-ring 213 can be driven by the first adjusting cylinder 213b, which in turn drives the upper part of the photovoltaic pile 500 to make fine adjustments. Similarly, two second limiting semi-rings 215 are movably mounted on one side of the second rotating platform 214 via a second adjusting cylinder 215b. The second adjusting cylinder 215b is fixed on the second rotating platform 214, and its piston rod is connected to the second limiting semi-ring 215. The second adjusting cylinder 215b can also make fine adjustments to the lower part of the photovoltaic pile 500 via the second limiting semi-ring 215, which can further ensure the positioning accuracy of the photovoltaic pile 500.

[0047] Furthermore, to facilitate the insertion of the photovoltaic pile 500, the upper part of both the first positioning hole and the second positioning hole is provided with an inclined guide surface 215c. The guide surface 215c can guide the photovoltaic pile 500 so that it can smoothly enter the first positioning hole and the second positioning hole, thereby improving the installation efficiency.

[0048] Specifically, the lifting and translating mechanism 300 is the core device for photovoltaic bracket installation. It includes a base frame 340, a top frame 310, and a lifting unit. The base frame 340 is movably mounted on the hull 100. The top frame 310 is used to hold the photovoltaic bracket and is raised and lowered on the base frame 340 via the lifting unit. The lifting unit drives the top frame 310 to move up and down. When the base frame 340 moves horizontally, the photovoltaic bracket located on the top frame 310 can be driven to move in both directions via the base frame 340 and the lifting unit. When installing the photovoltaic pile 500, the photovoltaic bracket can be moved to a position that avoids the photovoltaic pile 500 via the base frame 340 and the lifting unit. After the photovoltaic pile 500 is installed, the top frame 310 is first lifted by the lifting unit, so that the photovoltaic bracket legs... The bottom height is higher than the top height of the photovoltaic pile 500. Then, the photovoltaic bracket is driven to move horizontally through the base frame 340 so that the multiple legs of the photovoltaic bracket are aligned with the center of the multiple photovoltaic piles 500. In this embodiment, the photovoltaic bracket has four legs, and the photovoltaic piles 500 also have four legs. The four legs of the photovoltaic bracket are driven to be directly above the center of the four photovoltaic piles 500. Then, the lifting unit can drive the photovoltaic bracket to descend so that each leg of the photovoltaic bracket abuts against the top of the corresponding photovoltaic pile 500, thereby achieving the positioning and installation of the photovoltaic bracket. Since the base frame 340 and the lifting unit are both arranged on the hull 100, the stability is good when they drive the photovoltaic bracket to move, which can ensure the positioning accuracy of the photovoltaic bracket and improve the installation efficiency of the photovoltaic bracket.

[0049] Furthermore, in order to realize the horizontal movement of the top frame 310, the lifting and translation mechanism 300 also includes a first guide rail 330, which is arranged on the hull 100 along the length of the hull 100. The base frame 340 is movably mounted on the first guide rail 330, thereby realizing the movement of the base frame 340 along the length of the hull 100, which in turn drives the top frame 310 to move horizontally in sync.

[0050] Furthermore, the lifting unit includes four lifting cylinders 320, which are respectively installed at the four corners of the top of the base frame 340. The piston rods of the four lifting cylinders 320 can connect with the four corners of the bottom of the top frame 310, which can lift the four corners of the top frame 310 at the same time, making the lifting and lowering of the top frame 310 more stable and ensuring the precise docking of the photovoltaic bracket and the photovoltaic pile 500.

[0051] Specifically, the hoisting mechanism 400 is an auxiliary part of the construction device. The hoisting mechanism 400 includes a tower 410 and a boom 420. The tower 410 is fixed on the hull 100, and the boom 420 is movably installed on the top of the tower 410 and is used to hoist the photovoltaic pile 500 to the positioning unit 210. The boom 420 can also be used to hoist a vibratory hammer for the construction of the photovoltaic pile 500. The existence of the hoisting mechanism 400 greatly improves the construction efficiency and allows the entire installation process to be carried out continuously.

[0052] In this embodiment, a pile-driving mechanism installed on the hull 100 is also included to drive the photovoltaic pile into a preset hole.

[0053] The construction device for the offshore photovoltaic power generation unit, through the cooperation of the positioning mechanism 200 and the lifting and translating mechanism 300, can ensure the driving accuracy of the photovoltaic piles 500 and the installation accuracy of the photovoltaic brackets, which greatly improves the construction efficiency and installation quality of the offshore photovoltaic power generation unit. At the same time, the anchoring system of the hull 100 and the auxiliary role of the hoisting mechanism 400 make the entire construction process safer and more efficient.
