Description

Technical Field

[0001] This invention relates to the field of floating photovoltaic technology, and in particular to a floating photovoltaic delivery platform and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In recent years, the development of floating photovoltaic systems in freshwater areas such as reservoirs and lakes has been rapid. Currently, the assembly and deployment of floating photovoltaic systems mostly rely on small boats for pushing. These small boats are relatively expensive, and their streamlined bow shape helps reduce water resistance and increase the boat's speed. They can be used for towing when deploying floating photovoltaic strings. However, when the strings are close to the array, there is no room for operation, so they need to be pushed. During pushing, the streamlined and rounded shape of the small boat's end makes it impossible to effectively connect with the floats of the sub-strings, and the bow end is prone to damaging the photovoltaic modules. Therefore, it is impossible to complete the sub-string pushing into the array. Pushing requires manual labor, which significantly reduces efficiency and increases costs.

[0004] In addition, if water enters the cabin of a small boat during use, drainage is difficult, which seriously affects the boat's transport capacity and safety. Furthermore, since the construction site is basically a temporary dock, and small boats do not have rain shelters or other devices, a large amount of water can easily accumulate inside the boat during rainfall, and drainage is difficult after the water accumulates. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a floating photovoltaic (PV) pusher platform and its operating method. An easily detachable pusher device is added to the bow of the hull, facilitating contact between the platform and the PV strings, making it easier to control the PV strings, improving the efficiency of string array entry, and avoiding damage to the clamp-shaped device due to impacts with the shore dock. It can also be used as a transport platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The first aspect of this invention provides a floating photovoltaic delivery platform.

[0008] A floating photovoltaic push platform includes a hull, a wire rope suspension column, a wire rope, a wire rope tensioning device, a second circular pipe, a pin device, a clamp device, and a clamp device diagonal brace.

[0009] The bottom end of the steel wire rope suspension column is fixed to the hull, and the top end is connected to one end of the steel wire rope tensioning device. The other end of the steel wire rope tensioning device is used to connect one end of the steel wire rope, and the other end of the steel wire rope is connected to the clamp-shaped device.

[0010] The clamp-shaped device consists of two steel plates welded together, with an included angle between the two steel plates for contacting the string;

[0011] One end of the clamp-shaped device is fixedly connected to the clamp-shaped device, and the other end is fixedly connected to the second round tube, forming a pushing device;

[0012] The pin device is located at the bow of the hull and is used to connect the second round tube;

[0013] The disassembly and folding of the pushing device are achieved through the cooperation of the second round tube and the pin device, as well as the cooperation of the wire rope tensioning device and the wire rope.

[0014] Furthermore, the wire rope is composed of multiple segments, and the wire ropes of different segments are connected by a spring device.

[0015] Furthermore, it also includes column bracing;

[0016] One end of the column brace is fixedly connected to the side of the steel wire rope suspending the column, and the other end is fixed to the hull.

[0017] Furthermore, the shortest distance from the bottom end of the steel wire rope suspension column to the pin device is less than the shortest distance from the clamp device to the pin device.

[0018] Furthermore, the main frame of the hull is made of galvanized angle steel and reinforced with flat iron for added density.

[0019] The main frame is filled with foam board, and sheet metal is laid on the bottom and sides of the main frame before the foam board is filled.

[0020] Furthermore, the latch device includes a first circular tube and a third circular tube;

[0021] The first and third circular tubes are welded to the bow of the ship, and the central axes of the first and third circular tubes are on a straight line.

[0022] Furthermore, the pin device also includes a rotating shaft and a limiting device;

[0023] When in use, the second round tube is placed between the first round tube and the third round tube, and after the rotating shaft passes through the first round tube, the second round tube and the third round tube, the limiting device passes through the through hole opened on the rotating shaft to prevent the rotating shaft from falling out of the first round tube, the second round tube and the third round tube.

[0024] Furthermore, railings are provided on both sides of the top of the hull.

[0025] Furthermore, a mechanical propeller is mounted at the stern of the hull, and the mechanical propeller is connected to the hull via a pin connection.

[0026] A second aspect of the present invention provides a method for operating a floating photovoltaic delivery platform as described in the first aspect, comprising the following steps:

[0027] When pushing the string into the array, the clamp device contacts the string and pushes the string to the target;

[0028] During folding, after separating the wire rope from the wire rope tensioning device, pull the wire rope. The second round tube and the pin device work together to fold the pushing device to the top of the hull.

[0029] During disassembly, the pushing device can be removed by separating the wire rope from the wire rope tensioning device and separating the second round tube from the pin device.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The present invention discloses a floating photovoltaic delivery platform, which is completely tailored to the actual needs of the site. The platform head is equipped with a clamp-shaped device that is easy to disassemble, which facilitates the contact between the platform and the photovoltaic string floats, makes it easy to control the sub-string floats, and is highly practical and convenient to use when the strings are arrayed. It avoids damage to the components by the platform and can also avoid damage to the clamp-shaped device due to impact with the shore dock. It can also be used as a transportation platform.

[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0043] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0044] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0045] Example 1

[0046] Embodiment 1 of the present invention provides a floating photovoltaic push platform.

[0047] This embodiment provides a floating photovoltaic delivery platform, such as... Figure 1 and Figure 2 As shown, it includes hull 1, railing 2, power motor mounting point 3, wire rope suspension column 4, column diagonal brace 5, wire rope 6, wire rope tensioning device 7, spring device 8, pin device 9, clamp device 10, clamp device diagonal brace 11, and second round pipe 904.

[0048] like Figure 1 and Figure 2As shown, hull 1 includes a main frame, an outer sheet metal cladding of the main frame, and foam board filling within the main frame. The main frame is boat-shaped, with a recommended height of 60cm. The top, bottom, and side main frames of hull 1 are constructed using ∠45×5 galvanized angle steel, reinforced with -40×4 flat iron welded to the main frame for reinforcement. Foam board is filled within the main frame; before filling, a 0.25mm thick sheet metal cladding is added to the bottom and sides of the main frame to reduce the floating platform's resistance. After foam board filling, the upper surface of hull 1 is flat, facilitating material placement and transportation. To provide a better working environment for operators and prevent slipping during use, a PVC roll carpet is laid on the upper surface of the foam board before the upper (top) main frame is welded for reinforcement. The gaps between foam boards and between the foam board and the sheet metal are sealed with polyurethane foam.

[0049] A motor mounting point 3 is located at the stern of the main frame for mounting a mechanical propeller. The mechanical propeller is connected to the hull 1 via a pin connection for easy maintenance and replacement of the mechanical equipment. After the hull 1 is assembled, an 8-horsepower diesel generator propeller is mounted. To prevent excessive draft due to the weight of the motor at the stern, the stern of the main frame is appropriately widened, meaning the stern of the main frame is wider than the bow.

[0050] Railings 2 are installed on both sides of the top of the hull 1 to prevent people from falling into the water. The railings 2 are welded to the main frame.

[0051] A pin device 9 is installed at the bow of the hull 1 for connecting detachable pushing devices (including clamp-shaped device 10, clamp-shaped device diagonal brace 11, and second circular tube 904) for cascading into array. When used as a transport platform, the pushing devices can be temporarily removed or folded to the upper surface of the hull 1. The pushing devices are foldable and detachable, allowing for better use as a transport platform after removal. When the pushing platform docks, the pushing devices are folded to prevent damage to the clamp-shaped device 10 due to impact with the dock.

[0052] like Figure 5 As shown, a pin device 9 is provided at the bow of the hull 1. The pin device 9 includes a rotating shaft 901, a limiting device 902, a first round tube 903, and a third round tube 905. The first round tube 903 and the third round tube 905 are welded to the top of the bow of the hull 1, and the central axes of the first round tube 903 and the third round tube 905 are on a straight line. In use, a second round tube 904 is placed between the first round tube 903 and the third round tube 905, and the rotating shaft 901 passes through all the round tubes. The diameter of the top end of the rotating shaft 901 is larger than that of the round tubes, and a through hole is opened at the bottom end of the rotating shaft 901 for the limiting device 902 to pass through, so that the rotating shaft 901 cannot fall out in the round tube 903.

[0053] The shaft 901 is T-shaped; or, the shaft 901 is a Φ20 round steel pin.

[0054] The limiting device 902 can be a bolt or a nut.

[0055] like Figure 2 As shown, there are at least two clamp-shaped device diagonal braces 11. One end of the clamp-shaped device diagonal brace 11 is fixedly connected (welded) to the clamp-shaped device 10, and the other end is fixedly connected (welded) to the second round tube 904.

[0056] Among them, the clamp-shaped device diagonal brace 11 is made of DN25 steel pipe.

[0057] A clamp-shaped device 10 is installed at the bow of the hull 1, which is used as a contact device between the floating platform and the string when the string is arrayed. It is simple and practical and avoids damage to the floating body and photovoltaic modules by the hull 1.

[0058] like Figure 2 and Figure 4 As shown, the clamp-like device 10 consists of two 5mm thick steel plates welded together. The two plates are 500mm long, with their long sides welded together. The two plates have different widths: one is 150mm wide and the other is 100mm wide, with an included angle of 135° between them. The clamp-like device's diagonal brace 11 securely connects to the narrower steel plate, and in use, the narrower plate lies below the wider plate, perpendicular to the hull plane.

[0059] like Figure 6 As shown, the clamp-shaped device 10 has three stiffening ribs 12. These stiffening ribs are located on the opposite side of the clamp-shaped device that contacts the photovoltaic string. Figure 4 As shown, the wire rope suspension point 111 is the opening on one of the stiffening ribs.

[0060] The surface of the clamp device 10 is covered with a thin foam board to reduce damage to the float when the small string is loaded into the formation.

[0061] At the top of the hull 1, a steel wire rope suspension column 4 is fixed between the pin device 9 and the stern. The bottom end of the steel wire rope suspension column 4 is fixedly connected to the hull 1, and the top end has a through hole for passing through and fixing the steel wire rope 6.

[0062] Among them, the steel wire rope suspension column 4 uses DN40 steel pipe.

[0063] In one implementation, the side of the steel wire rope suspension column 4 is also fixedly connected to the column diagonal brace 5. One end of the column diagonal brace 5 is fixedly connected to the side of the steel wire rope suspension column 4, and the other end is fixed to the hull 1. The column diagonal brace 5 is made of DN25 steel pipe. The steel wire rope suspension column 4, the column diagonal brace 5 and the hull 1 form a triangle, which is beneficial to the structural stability.

[0064] As one implementation method, the steel wire rope suspension column 4 is set at the bow of the ship.

[0065] One end of the wire rope 6 is connected to the top of the wire rope suspension column 4, and the other end is fixed to the clamp-shaped device diagonal brace 11. The clamp-shaped device diagonal brace 11 has a wire rope suspension point 111 on the stiffening rib in the middle of the wider steel plate for connecting and fixing the wire rope 6.

[0066] Among them, wire rope 6 uses 10mm wire rope.

[0067] In one embodiment, the top of the wire rope suspension column 4 is connected to one end of the wire rope tensioning device 7 via a rope, and the other end of the wire rope tensioning device 7 is used to connect the wire rope 6, so as to achieve the connection between the wire rope 6 and the top of the wire rope suspension column 4.

[0068] To further reduce the impact and damage to the buoys during commissioning, the clamp-like device 10 is connected to the hull 1 by an elastic device, such as... Figure 2 As shown, the wire rope 6 can be in multiple segments, and the different segments of the wire rope 6 are connected by a spring device 8. The spring device 8 is a spring.

[0069] Among them, such as Figure 3 As shown, the wire rope tensioning device 7 is an OC type wire rope tensioner. The O-shaped hook of the OC type wire rope tensioner is used to connect the top of the suspension column 4 with the wire rope through the rope. The C-shaped hook of the OC type wire rope tensioner is used to connect the wire rope 6.

[0070] During installation, the welding sequence for the main frame is as follows: first, weld the bottom and side ∠45×5 galvanized angle steel main frames; after the main frame welding is completed, weld a -40×4 flat iron frame to avoid insufficient constraint on the foam due to small frame gaps; during the main frame welding, pre-set the installation positions for the steel wire rope suspension columns, and install angle steel keels at these positions; weld the first and third round pipes to the top of the front end of the main frame; the installation position of the mechanical propeller at the tail of the platform is also reinforced, and two sections of perforated No. 10 channel steel are welded to the rear end of the main frame, and the two sections of perforated No. 10 channel steel are used to achieve pin connection with the No. 8 channel steel corresponding to the mechanical propeller; after the bottom and side frames are welded, sheet metal is fixed, and the sheet metal is connected to the frame using self-tapping bolts. When connecting, ensure that the nut of the self-tapping bolt is on the side in contact with water, and the joints between the sheet metal are... After the sheet metal is installed using a bite-edge method, the joints and self-tapping bolt holes are sealed with sealant. After the sheet metal is laid, foam boards are laid in layers, and the gaps between the foam boards and between the foam boards and the sheet metal are filled with polyurethane foam to prevent water ingress and enhance the platform's buoyancy. After the foam boards are laid, the top layer of PVC roll carpet is laid. After the roll carpet is laid, the top frame is welded. During welding, measures must be taken to prevent burns to the foam boards and PVC carpet. After connecting the wire rope tensioner O-hooks to the top of the wire rope suspension column, the wire rope suspension column and the column diagonal brace are welded to the top frame in sequence. The finished propeller machinery at the stern of the hull needs to be welded with channel steel to connect with the platform for easy connection with the platform pin. At least two tires are hung on both sides of the push platform's head to further prevent damage to the floats or components when the platform comes into contact with the tandem or array.

[0071] In use, the second round tube of the pushing device (including the clamping device, the clamping device's diagonal brace, and the second round tube) is placed between the first and third round tubes. After the rotating shaft passes through all the round tubes, the limiting device passes through the through hole of the rotating shaft to prevent the rotating shaft from falling out of the round tubes. One end of the wire rope is fixed to the clamping device, and the other end is fixed to the top of the wire rope suspension column (specifically, the C-hook of the wire rope tensioner is connected to the other end of the wire rope). The tilt angle is controlled by the wire rope suspension, and the connection is made through the wire rope tensioner. The wire rope tensioner is also connected to the spring device to reduce the impact when the clamping device contacts the float and avoid damage to the float. The outer spacing of the diagonal brace of the wire rope suspension column (i.e., the shortest distance from the bottom of the wire rope suspension column to the rotating shaft of the pin device) must be less than the minimum net inner spacing of the diagonal brace of the clamping device (i.e., the shortest distance from the clamping device to the rotating shaft of the pin device) to facilitate the folding of the pushing device to the platform when docking.

[0072] When pushing the string into the array, the two sides of the clamp-shaped device contact the string, pushing the sub-string (string) to be added to the target. The string consists of several floats and photovoltaic panels.

[0073] When folding is required, such as Figure 5 As shown, after separating the wire rope from the C-shaped hook of the wire rope tensioner, pull the wire rope along the folding direction line of the clamp-shaped device to fold the pushing device to the top of the platform.

[0074] During disassembly, remove the limiting device to pull out the shaft. Once the shaft is pulled out and the C-hook of the wire rope tensioner disengages, the clamp device can be removed.

[0075] This embodiment provides a floating photovoltaic push platform that facilitates contact between the platform and the incoming sub-strings, is simple and practical, and significantly improves the efficiency of sub-string entry into the array.

[0076] This embodiment provides a floating photovoltaic propulsion platform, which is a simple propulsion platform. The platform is equipped with a power mechanism and can completely replace small boats. It is easy to manufacture, and while increasing safety, it significantly reduces the equipment purchase cost. It has high buoyancy, and its cost is much lower than that of small boats. It is more practical than small boats and has good economic benefits. It has high promotion value. The tail is equipped with a pin to connect to the finished propeller mechanism, which facilitates the inspection and replacement of mechanical equipment and makes operation and maintenance convenient.

[0077] This embodiment provides a floating photovoltaic delivery platform with a planar surface, which facilitates material transportation and loading / unloading, eliminates the problem of water ingress and accumulation in the hull, and ensures high safety.

[0078] The floating photovoltaic pushing platform provided in this embodiment is completely tailored to the actual needs of the site. The platform head is equipped with a clamp-shaped device that is easy to disassemble, which facilitates the contact between the platform and the photovoltaic string float, making it easy to control the sub-string float. It is highly practical and convenient to use when the string is being arrayed, and avoids damage to the components by the platform.

[0079] Example 2

[0080] Embodiment 2 of the present invention provides a method for operating a floating photovoltaic push platform as in Embodiment 1, comprising the following steps:

[0081] When pushing the string into the array, the clamp device contacts the string and pushes the string to the target;

[0082] During folding, after separating the wire rope from the wire rope tensioning device, pull the wire rope. The second round tube and the pin device work together to fold the pushing device to the top of the hull.

[0083] During disassembly, the pushing device can be removed by separating the wire rope from the wire rope tensioning device and separating the second round tube from the pin device.
