Description

Technical Field

[0001] This application relates to the field of marine photovoltaic technology, and more specifically, to a structural outrigger gripping device and a photovoltaic module construction vessel. Background Technology

[0002] Offshore photovoltaics is a renewable energy technology that deploys solar photovoltaic power generation systems in water bodies such as oceans, lakes, or reservoirs. It combines photovoltaic power generation with marine engineering and has become an important area of ​​exploration in the global new energy field in recent years.

[0003] In recent years, with the development of offshore photovoltaic (PV) systems, pile-based fixed offshore PV systems have begun to enter a stage of large-scale production. For example... Figures 1-3 As shown, the main structural form currently is the "large flat panel" scheme, which mainly consists of four steel pipe piles 101 plus a photovoltaic module on top. The photovoltaic module is generally connected into a whole using a truss or grid support frame 104. The bottom of the support frame 104 is equipped with structural legs 103 for inserting and engaging the steel pipe piles 101. The ends of the structural legs 103 have tips 102 to facilitate insertion into the steel pipe piles 101. In actual installation, the support frame can be hoisted and installed as a whole with the photovoltaic module. In existing technology, floating cranes are generally used for offshore hoisting of the photovoltaic module, and the connection between the structural legs 103 of the support frame 104 and the steel pipe piles 101 is controlled.

[0004] Existing technologies require substantial construction equipment resources, including at least floating cranes and transport vessels. Furthermore, this type of photovoltaic module necessitates pre-reserved locations for lifting points at the top, leaving these locations unused and preventing the placement of photovoltaic modules. This also impacts the overall scale of the offshore photovoltaic power plant.

[0005] Therefore, how to reduce the number of offshore construction vessels and machinery used while ensuring that the top of the support frame can be fully covered with photovoltaic modules to maximize the utilization of the top area of ​​the support frame is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a structural outrigger gripping device to reduce the number of offshore construction vessel and machinery resources used, while enabling the top of the support frame to be fully covered with photovoltaic modules, thereby maximizing the utilization of the top area of ​​the support frame.

[0066] The embodiment of the present application discloses a photovoltaic module construction ship, so as to reduce the number of marine construction ship machine resources, and enable the top of the support frame to be fully paved with photovoltaic components, and maximize the use of the top area of the support frame.

[0067] The embodiment of the present application also discloses a photovoltaic module construction ship with the structural leg grabbing device.

[0068] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not have any limiting effect on the application content recited in the claims. In addition, the entire content of the configuration represented in the following embodiments is not limited to what is necessary as a solution to the application recited in the claims. It should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0069] As shown in Figure 4 , Figure 7 and Figure 8 , the structural leg grabbing device 200 disclosed by the embodiment of the present application is arranged on the hull 300, and is used for holding the structural leg 103. It should be noted that, according to different devices to be installed, the structural leg 103 can be the structural leg 103 of different devices. For example, when the device to be installed is the photovoltaic module shown in the figure, the structural leg 103 is the structural leg 103 of the photovoltaic module; when the device to be installed is not limited to the photovoltaic module, as long as the device has the structural leg 103. Figures 1-3

[0070] The structural leg grabbing device 200 disclosed by the embodiment includes a lifting beam 204, a lifting driving device 203, an extension beam 206, an extension driving device 207, an arm holding assembly 201 and an opening and closing driving device 208.

[0071] The lifting beam 204 can be driven by the lifting driving device 203 to perform lifting action. When the lifting beam 204 performs lifting action, the device mounted thereon can be driven to perform synchronous lifting action. The lifting beam 204 is arranged on the hull 300, but the lifting action of the lifting beam 204 should not be limited, that is, the connection relationship between the lifting beam 204 and the hull 300 should be kept free.

[0072] ​The telescopic beam 206 is arranged on the lifting beam 204 and can perform telescopic action in the direction of approaching and moving away from the lifting beam 204. Taking the center line in the width direction of the ship body 300 as a reference line, the distance to the reference line can be adjusted when the telescopic beam 206 performs telescopic action, that is, the telescopic direction of the telescopic beam 206 is in the direction of approaching and moving away from the lifting beam 204.

[0073] The telescopic driving device 207 is used to drive the telescopic beam 206 to perform telescopic action, so that the distance between the arm embracing assembly 201 and the reference line can be changed by driving the telescopic beam 206 to perform telescopic action through the telescopic driving device 207 according to the construction requirement, that is, the distance between the arm embracing assembly 201 and the structural leg 103 can be changed.

[0074] The arm embracing assembly 201 is arranged at the telescopic end of the telescopic beam 206, that is, the telescopic beam 206 and the arm embracing assembly 201 can be driven to perform lifting action when the lifting beam 204 performs lifting action, and the arm embracing assembly 201 can be driven to perform telescopic action when the telescopic beam 206 performs telescopic action, so that the position of the arm embracing assembly 201 in space can be adjusted through the telescopic beam 206 and the lifting beam 204.

[0075] The arm embracing assembly 201 is driven by the opening and closing driving device 208 to perform opening and closing action to tightly embrace and release the structural leg 103. When the arm embracing assembly 201 is opened, the structural leg 103 can be released, and when the arm embracing assembly 201 is closed, the structural leg 103 can be tightly embraced.

[0076] It should be noted that the arm embracing assembly 201 can realize the connection between the photovoltaic module and the structural leg grabbing device 200 after tightly embracing the structural leg 103, and if the structural leg grabbing device 200 is installed on the ship body 300, the photovoltaic module can be assembled to the ship body 300 through the structural leg grabbing device 200, so as to facilitate the transportation of the photovoltaic module by the ship body 300.

[0077] The arm embracing assembly 201 can be connected with the structural leg 103 through friction to achieve tight embrace, that is, under the action of the friction between the arm embracing assembly 201 and the structural leg 103, the structural leg 103 will not slide downward due to gravity. Of course, a first limiting part can be arranged on the inner wall of the arm embracing assembly 201, and a second limiting part can be arranged on the structural leg 103, and when the arm embracing assembly 201 embraces the structural leg 103, the first limiting part and the second limiting part abut against each other, and then the first limiting part limits the downward sliding of the structural leg 103 to achieve tight embrace. The way in which the arm embracing assembly 201 tightly embraces the structural leg 103 in the embodiment is not limited, as long as the weight of the photovoltaic module can be supported and the relative sliding between the arm embracing assembly 201 and the structural leg 103 can be prevented.

[0078] In summary, the structural leg grabbing device 200 disclosed in the embodiments of the present application can be arranged on the ship body 300, so that the ship body 300 has the functions of a transport ship and an installation ship. The structural leg grabbing device 200 has the arm embracing assembly 201 and the opening and closing driving device 208. The opening and closing driving device 208 can drive the arm embracing assembly 201 to perform opening and closing actions, so that the arm embracing assembly 201 tightly embraces and releases the structural leg 103. When the arm embracing assembly 201 tightly embraces the structural leg 103, the photovoltaic module can be fixed on the ship body 300, and the ship body 300 can be used to transport the photovoltaic module to a target installation position.

[0079] The structural leg grabbing device 200 also has the lifting beam 204 and the lifting driving device 203. The lifting driving device 203 can drive the lifting beam 204 to drive the arm embracing assembly 201 to perform lifting actions. When the lifting beam 204 drives the arm embracing assembly 201 to rise, the structural leg 103 located above can be grabbed. When the lifting beam 204 drives the arm embracing assembly 201 to descend, the structural leg 103 can be driven to descend and be inserted into the steel pipe pile.

[0080] The structural leg grabbing device 200 also has the telescopic beam 206 and the telescopic driving device 207. The telescopic driving device 207 can drive the telescopic beam 206 to drive the arm embracing assembly 201 to perform telescopic actions. When the telescopic beam 206 drives the arm embracing assembly 201 to extend outward, the structural leg located on the outer side can be grabbed. When the telescopic beam 206 drives the arm embracing assembly 201 to retract, the arm embracing assembly 201 can be driven to avoid the structural leg and the steel pipe pile, so that the ship body 300 can drive away from the target position without being interfered by the structural leg and the steel pipe pile.

[0081] The structural leg grabbing device 200 provided in the present application can be arranged on the ship body 300. The photovoltaic module can be transported to a target sea area, and the installation of the photovoltaic module can also be completed. The valuable floating crane resources are saved, and the ship machine cost is reduced. Moreover, the photovoltaic module does not need to be hoisted, so that the top of the support frame does not need to reserve a hoisting point. The top of the support frame can be fully paved with photovoltaic modules, and the top area of the support frame is maximally utilized.

[0082] As shown in FIGS. Figure 7 and Figure 8 In an embodiment of the present application, the arm embracing assembly 201 can include the fixed arm 2012 and the movable arms 2011. The fixed arm 2012 is fixed to the telescopic end of the telescopic beam 206. The movable arms 2011 are two and are respectively hinged to the two ends of the fixed arm 2012. That is, one of the movable arms 2011 is hinged to one end of the fixed arm 2012, and the other movable arm 2011 is hinged to the other end of the fixed arm 2012. The two movable arms 2011 can be symmetrically arranged along the fixed arm 2012, or can be asymmetrically arranged.

[0083] The fixed holding arm 2012 and the two movable holding arms 2011 enclose a space for holding the structural leg 103, and the opening and closing driving device 208 is used to drive the movable holding arm 2011 to swing. Each movable holding arm 2011 is correspondingly provided with an opening and closing driving device 208, and each opening and closing driving device 208 drives the corresponding movable holding arm 2011 to rotate along the hinge shaft of the fixed holding arm 2012 to complete the opening and closing action.

[0084] Taking the opening and closing driving device 208 as a hydraulic cylinder as an example, the end of the movable holding arm 2011 which is not hinged to the fixed holding arm 2012 is defined as the free end. When the piston rod of the opening and closing driving device 208 is retracted, the movable holding arm 2011 can be pulled to open, that is, the free ends of the two movable holding arms 2011 are away from each other, so that the distance between the free ends of the two movable holding arms 2011 is greater than the diameter of the structural leg 103, so that the structural leg 103 can enter the wrapping range of the holding arm assembly 201, and the structural leg 103 can also leave the wrapping range of the holding arm assembly 201.

[0085] It should be noted that the holding arm assembly 201 can also only include movable holding arms 2011, that is, it does not contain the fixed holding arm 2012. One end of the two movable holding arms 2011 is hinged and hinged to the telescopic end of the telescopic beam 206. The other end of the two movable holding arms 2011 forms a free end, which can be controlled by the opening and closing driving device 208 to approach and move away from each other, so as to realize holding and loosening the structural leg 103.

[0086] Further, the fixed holding arm 2012 and the movable holding arm 2011 each have an arc surface portion for abutting the structural leg 103. By abutting the arc surface portion and the structural leg 103, the contact area with the structural leg 103 can be increased, thereby increasing the clamping effect and preventing the structural leg 103 from loosening. The diameter of the arc surface portion can be designed to be the same as or slightly smaller than the diameter of the structural leg 103. Of course, the diameter of the arc surface portion can also be designed to be greater than the diameter of the structural leg 103. When holding the structural leg 103, the free ends of the two movable holding arms 2011 need to cross, so that the space enclosed by the fixed holding arm 2012 and the two movable holding arms 2011 can clamp the structural leg 103.

[0087] In the embodiment, the structures of the fixed holding arm 2012 and the movable holding arm 2011 can be designed to be the same, that is, the arc of the arc surface portion of the fixed holding arm 2012 and the movable holding arm 2011 is the same, so that the contact area of the fixed holding arm 2012 and the movable holding arm 2011 with the structural leg 103 is the same. Moreover, when the structures of the fixed holding arm 2012 and the movable holding arm 2011 are designed to be the same, the processing cost can be reduced, and the interchangeability of the fixed holding arm 2012 and the movable holding arm 2011 is improved.

[0088] In an embodiment of the present application, the fixed holding arm 2012 and the movable holding arm 2011 are provided with a buffer layer on the surface in contact with the structural leg 103. By providing a buffer layer on the fixed holding arm 2012 and the movable holding arm 2011, the fixed holding arm 2012 and the movable holding arm 2011 are in contact with the structural leg 103 through the buffer layer, which can prevent the fixed holding arm 2012 and the movable holding arm 2011 made of metal from hard contact with the structural leg 103 and damage the structural leg 103. The buffer layer can be made of rubber, silica gel or any other flexible material that can be elastically deformed.

[0089] As shown in Figure 6 The structural leg grabbing device 200 can further include a guide column 202 arranged on the ship body 300, and the lifting beam 204 is in sliding fit with the guide column 202. The guide column 202 can guide the lifting direction of the lifting beam 204. One end of the lifting driving device 203 is connected to the guide column 202, and the other end is connected to the lifting beam 204. Specifically, one end of the lifting driving device 203 can be hinged to the guide column 202 through a hinge support, and the other end can be hinged to the lifting beam 204 through a hinge support. The two ends of the lifting driving device 203 are connected to the guide column 202 and the lifting beam 204 through hinge supports, which can increase the degree of freedom, prevent the lifting driving device 203 from being stuck due to slight deflection of the lifting beam 204 during lifting, and adjust the posture and angle of the lifting driving device 203 when the lifting beam 204 deviates during movement, thereby preventing the lifting driving device 203 from being stuck.

[0090] The lifting driving device 203 can be a hydraulic cylinder, and the cylinder body of the lifting driving device 203 can be connected to the guide column 202, and the piston rod can be connected to the lifting beam 204.

[0091] The lifting beam 204 can be sleeved on the guide column 202, that is, the lifting beam 204 can be designed as a tubular structure, and in order to prevent the lifting beam 204 from rotating, the lifting beam 204 can be designed as a rectangular tube structure. The lifting beam 204 is sleeved on the guide column 202, which can ensure the stability of the lifting beam 204. In order to balance the lifting driving force, two lifting driving devices 203 can be arranged on each lifting beam 204, and the two lifting driving devices 203 can be symmetrically arranged on opposite sides of the guide column 202. Of course, those skilled in the art can understand that the lifting driving device 203 can also be provided with only one.

[0092] In order to reduce the friction between the lifting beam 204 and the guide column 202, a sliding bearing can be arranged therebetween to reduce the friction therebetween and facilitate the lifting action of the lifting beam 204.

[0093] The top of the guide column 202 can be provided with a limiting baffle 205 limiting the upper limit position of the lifting beam 204, so as to prevent the lifting beam 204 from being lifted to be separated from the guide column 202, and improve the safety during lifting.

[0094] As shown in the drawings, Figure 6 In an embodiment of the present application, the telescopic beam 206 can include a first structural beam and a second structural beam which are nested and slidingly fitted with each other, the first structural beam is connected to the lifting beam 204, and the arm embracing assembly 201 is arranged on the second structural beam. One of the first structural beam and the second structural beam can be sleeved on the outside of the other.

[0095] One end of the telescopic driving device 207 is connected to the lifting beam 204 or the first structural beam, and the other end is connected to the second structural beam. Specifically, one end of the telescopic driving device 207 can be hinged to the lifting beam 204 or the first structural beam through a hinge support, and the other end is hinged to the second structural beam through a hinge support.

[0096] The extension direction of the first structural beam and the second structural beam can be perpendicular to the extension direction of the lifting beam 204 and the guide column 202. Since the first structural beam is connected to the lifting beam 204 and is perpendicular, and the weight of the photovoltaic module acts on the telescopic beam 206, the shear force at the connection between the first structural beam and the lifting beam 204 is large, and the connection between the first structural beam and the lifting beam 204 is prone to fracture. Based on this, in the present embodiment, a diagonal brace (not shown in the drawings) can be added, which is connected to the first structural beam and the lifting beam 204 respectively and forms an acute angle with the first structural beam and the lifting beam 204 respectively. The diagonal brace can be provided with multiple diagonal braces to increase the supporting capacity and increase the strength of the connection between the first structural beam and the lifting beam 204.

[0097] In an embodiment of the present application, the telescopic driving device 207 can be provided with at least two, and the two telescopic driving devices 207 are symmetrically arranged on opposite sides of the telescopic beam 206. In the present embodiment, arranging multiple telescopic driving devices 207 can ensure the centration of the first structural beam and the second structural beam at all times when the second structural beam is pushed and pulled to perform telescopic action, and avoid the situation that the first structural beam and the second structural beam are stuck due to larger friction on one side. Of course, the telescopic driving device 207 can also be provided with only one, and the present embodiment does not limit the specific number of telescopic driving devices 207.

[0098] Correspondingly, the lifting beam 204 can also be provided with two lifting driving devices 203 which are symmetrically arranged on opposite sides of the lifting beam 204.

[0099] As shown in the drawings, Figures 4-6As shown, the embodiment of the present application also discloses a photovoltaic module construction ship, which comprises a ship body 300 and a structural leg grabbing device 200 arranged on the ship body 300, and the structural leg grabbing device 200 is the structural leg grabbing device 200 disclosed in the above embodiment. The structural leg grabbing device 200 is the same as the number of the structural legs 103 of the photovoltaic module to be installed, and one-to-one correspondence.

[0100] The photovoltaic module construction ship provided by the present application has all the technical effects of the structural leg grabbing device 200, and details are not repeated here.

[0101] In the embodiment, the telescopic beam 206 points to the outside of the ship body 300, so that the arm embracing assembly 201 is located outside the side of the ship body 300, that is, the arm embracing assembly 201 is located outside the side of the ship body 300 at any position in the moving range. It should be noted that the projection of the moving range of the arm embracing assembly 201 on the plane where the deck of the ship body 300 is located can also intersect with the deck, that is, as long as the arm embracing assembly 201 can move out to the side of the ship body 300 when moving outward.

[0102] The structural leg grabbing device 200 can be welded on the ship body 300, or can be fixed on the ship body 300 in a detachable manner. For example, a plurality of mounting points can be arranged on the ship body 300, and the structural leg grabbing device 200 can be detachably arranged on the mounting points. The number of mounting points can be greater than the number of structural leg grabbing devices 200. For example, corresponding mounting points can be arranged according to a plurality of photovoltaic modules, so that when installing photovoltaic modules of corresponding specifications, each structural leg grabbing device 200 can be fixed on the corresponding mounting point; when installing photovoltaic modules of other specifications, each structural leg grabbing device 200 can be detached and fixed on the corresponding mounting point, thereby improving the application range of the photovoltaic module construction ship.

[0103] It should be noted that since the photovoltaic module generally has four structural legs 103, the structural leg grabbing device 200 can also be correspondingly arranged four. In order to ensure the inclined arrangement of the photovoltaic assembly of the photovoltaic module, the heights of the steel pipe piles 101 corresponding to the four structural legs 103 are not completely the same. The four structural legs 103 are arranged in two columns, and the height of the steel pipe pile 101 corresponding to one column of structural legs 103 is higher than that of the other column of steel pipe piles 101, so that in order to ensure that the photovoltaic module can be transported according to the angle after installation, the heights of the structural leg grabbing devices 200 corresponding to the two columns of structural legs 103 are also different (as shown in Figure 4 The height difference between the two columns of structural leg grabbing devices 200 is the same as the height difference between the two columns of steel pipe piles 101.

[0104] The photovoltaic module installation method disclosed by the embodiments of the present application is installed by using the photovoltaic module construction ship disclosed by the above embodiments, and includes a shipping step and an installation step.

[0105] The shipping step is a step of shipping the photovoltaic module.

[0106] As shown in Figure 9 , the photovoltaic module is transported to above the ship body 300, and specifically, the shipping can be performed by the SPMT (Self-Propelled Modular Transporter) axis vehicle 400, and of course, the shipping can also be performed by hoisting equipment. In order to ensure that the photovoltaic module has a certain height when the photovoltaic module is shipped, the structural leg 103 is located above the arm embracing assembly 201. The SPMT axis vehicle 400 can support the support frame 104 of the photovoltaic module by the support frame 500 to raise the height of the photovoltaic module.

[0107] As shown in Figure 10 , when the photovoltaic module is transported to the position corresponding to the structural leg 103 of the photovoltaic module and the arm embracing assembly 201, the lifting driving device 203 drives the lifting beam 204 to drive the arm embracing assembly 201 (at this time, the arm embracing assembly 201 needs to be in an open state) to rise until the structural leg 103 is inserted into the arm embracing assembly 201, and the arm embracing assembly 201 is driven to embrace the structural leg 103 by the opening and closing driving device 208.

[0108] As shown in Figure 11 , when the arm embracing assembly 201 embraces the structural leg 103, the SPMT axis vehicle 400 can withdraw from the ship body 300. The photovoltaic module construction ship can drive to the target installation position.

[0109] The installation step is a step of installing the photovoltaic module on the steel pipe pile 101.

[0110] As shown in Figure 12 , the ship body 300 drives to the target installation position, and the position of the ship body 300 is controlled so that the structural leg 103 corresponds to the steel pipe pile 101 of the target installation position one by one.

[0111] As shown in Figure 13 and Figure 14 , after the structural leg 103 is aligned with the steel pipe pile 101 one by one, the lifting driving device 203 drives the lifting beam 204 to drive the photovoltaic module to descend until the structural leg 103 is inserted into the steel pipe pile 101.

[0112] The installation step further includes a withdrawing step, and the withdrawing step is a step of withdrawing the photovoltaic module construction ship from the target sea area.

[0113] As shown in Figure 15As shown, the opening and closing drive device 208 drives the arm assembly 201 to open, causing the photovoltaic module construction vessel to disengage from the structural support leg 103.

[0114] like Figure 16 As shown, the telescopic drive device 207 drives the telescopic beam 206 to move the arm assembly 201 away from the structural support leg 103, that is, towards the hull 300, to prevent interference from the structural support leg 103 when the hull 300 sails away.

[0115] like Figure 17 As shown, since the structural support leg 103 does not interfere with the arm assembly 201, the hull 300 can move away from the target installation position.
