Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic transportation technology, and in particular to a marine photovoltaic platform transfer device. Background Technology

[0002] With the continuous development of the offshore photovoltaic industry, the installation and maintenance of photovoltaic modules at sea are becoming increasingly frequent. Several technical challenges exist in transporting photovoltaic modules from land to offshore installation platforms: First, as fragile components, photovoltaic panels require robust and reliable clamping and restraining structures during transportation and transfer to prevent slippage or damage during handling; second, the transfer device needs to have folding or storage capabilities to reduce its volume and improve operational flexibility in the limited space of offshore operations; third, traditional transport devices are easily entangled or obstructed by weeds or floating debris on the sea surface, affecting not only the ship's forward efficiency but also potentially causing propeller jamming and other malfunctions, thus impacting overall operational safety.

[0003] In existing technologies, some photovoltaic transfer devices lack reliable clamping and limiting mechanisms, which can easily cause the photovoltaic panels to sway or shift during the sliding process, and lack effective control over the sliding structure and limiting position. At the same time, most transport devices have a fixed volume and cannot be quickly stored according to the actual transport volume or operation scenario. In addition, some devices do not take effective measures to clear obstacles such as seaweed and floating objects during the sea surface propulsion process, resulting in low equipment operating efficiency and easy damage to the equipment. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing photovoltaic transfer devices, such as the lack of reliable clamping and limiting mechanisms, which can easily cause photovoltaic panels to sway or shift during sliding, and the lack of effective control over the sliding structure and limiting position. In addition, most transport devices have a fixed size and cannot be quickly stored according to the actual transport volume or operating scenario. Furthermore, some devices do not take effective measures to clear obstacles such as seaweed and floating objects during sea surface propulsion, resulting in low propeller operating efficiency and easy damage to the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a marine photovoltaic platform transfer device, comprising: a ship body, a connecting shaft rotatably connected to the bottom of the ship body, reciprocating screws fixedly connected to both ends of the connecting shaft, short rods fixedly connected to opposite ends of the two reciprocating screws, rotating plates fixedly connected to opposite ends of the two short rods, movable strips slidably connected to the outer surfaces of the two reciprocating screws, elongated holes formed on the outer surfaces of the two movable strips, limiting rods fixedly installed at the bottom of the ship body, the two movable strips sliding on the outer surfaces of the limiting rods, hollow frames fixedly connected to one end of the two limiting rods, grooves formed inside the two hollow frames, and two rotating rods movably embedded in the inner walls of the two hollow frames.

[0006] The technical effect of adopting the above-mentioned further solution is as follows: When the ship body is transported in the water, it drives the rotating plate to rotate. The rotating plate drives two reciprocating screws to rotate through the connecting shaft. After the two reciprocating screws rotate, they drive two movable strips to slide back and forth on their outer surface. The limiting rod limits the two movable strips. When the two movable strips move, they drive the two hollow frames to move. At this time, when the two hollow frames move towards the middle at the same time, the perforated plate rotates around the rotating rod as the center. At this time, the middle of the hollow frame is in an open state, reducing its resistance. When the two hollow frames move in opposite directions at the same time under the drive of the two movable strips, the perforated plate rotates around the rotating rod as the center again. At this time, the perforated plate is located on the surface of the groove, which can push the seaweed and floating garbage in front of the ship body to both sides, preventing them from affecting the forward movement of the ship. It also prevents the seaweed from entering the ship's propeller and affecting its operation.

[0007] In a preferred embodiment, a perforated plate is movably fitted onto the outer surface of each of the plurality of rotating rods, and the plurality of perforated plates are located on the outer surface of the groove. A placement plate is fixedly connected to the top of the outer surface of the ship body. A threaded rod is movably embedded on one side of the placement plate. One end of each of the two threaded rods is connected to a moving strip via a bearing. A plurality of sliding grooves are formed on the inner wall of the placement plate. The plurality of sliding grooves are evenly divided into two groups, and the two moving strips are slidably connected inside the two groups of sliding grooves.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: the photovoltaic panel is placed on the surface of the card hole, the photovoltaic panel slides along the upper surface of the card hole, slides to the upper surface of the placement plate, and then the moving bar is pushed to slide inside the slide groove by rotating the threaded rod, at which time the photovoltaic panel is clamped and fixed.

[0009] In a preferred embodiment, two fixing strips are fixedly installed on the top of the outer surface of the placement plate. The two fixing strips are located on opposite sides of two moving strips. A long rod is movably embedded on one side of the placement plate. Two U-shaped plates are movably sleeved on the outer surface of the long rod. U-shaped plates are slidably connected to the outer surfaces of the two U-shaped plates. A horizontal bar is fixedly connected to one end of the two U-shaped plates. Two hollow strips are fixedly installed on the side of the horizontal bar near the two U-shaped plates. Sliding strips are movably sleeved inside the two hollow strips. An L-shaped plate is fixedly connected to one side of each of the two U-shaped plates.

[0010] The technical effect of adopting the above-mentioned further solution is that the rotating threaded rod three disengages from the hole on the surface of the rectangular block, the rotating threaded rod two moves inside the L-shaped plate one, at this time the threaded rod two disengages from the inside of the locking hole, the U-shaped plate two slides on the inner wall of the U-shaped plate one, and the hollow strip slides on the outer surface of the sliding strip, which can be stored and the volume is reduced.

[0011] In a preferred embodiment, threaded rods are movably embedded inside both L-shaped plates, and locking holes are formed on the outer surfaces of both U-shaped plates. The threaded rods are movably embedded inside the two locking holes. A square groove is formed on the outer surface of one of the U-shaped plates. The outer surface of the ship body is connected to the L-shaped plate via a long strip. A pull rod is movably embedded inside the L-shaped plate. A limiting block is fixedly connected to one end of the pull rod. A spring is provided on one side of the limiting block. A locking block is fixedly installed on the side of the limiting block away from the spring. The locking block is movably embedded inside the square groove.

[0012] The technical effect of adopting the above-mentioned further solution is: when the U-shaped plate 2 is rotated around the long rod 1 as the center, the pull rod is pulled to drive the limiting block to move. When the square groove is parallel to the card block, the card block is locked inside the square groove under the limiting action of the sliding strip, which can limit the entire feeding sliding mechanism.

[0013] In a preferred embodiment, a long rod 2 is movably embedded at the bottom of the horizontal bar, and two rectangular blocks are movably fitted on the outer surface of the long rod 2. A cylinder is fixedly connected to the bottom of the outer surface of each of the two rectangular blocks, and a support plate is fixedly connected to the bottom of each of the two cylinders. Two protrusions are fixedly connected to the bottom of the horizontal bar near the two rectangular blocks, and a threaded rod 3 is movably embedded inside each of the two protrusions. The two threaded rods 3 are movably embedded in the holes of the two rectangular blocks.

[0014] The technical effect of adopting the above-mentioned further solution is as follows: the cylinder rotates around the long rod 2 with the rectangular block as the center. At this time, the included angle between the cylinder and the cylinder is 90 degrees. At this time, the rotating threaded rod 3 moves inside the protrusion. At this time, the threaded rod 3 is embedded in the hole on the surface of the square groove to limit the cylinder. At this time, the support plate is supported on the ground and supports the upper feeding sliding mechanism.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. In this embodiment of the invention, when the boat body is transported in the water, it drives the rotating plate to rotate. The rotating plate drives two reciprocating screws to rotate through the connecting shaft. After the two reciprocating screws rotate, they drive two movable strips to slide back and forth on their outer surface. The limiting rod limits the two movable strips. When the two movable strips move, they drive the two hollow frames to move. When the two hollow frames move towards the middle at the same time, the perforated plate rotates around the rotating rod as the center. At this time, the middle of the hollow frame is in an open state, reducing its resistance. When the two hollow frames move in opposite directions at the same time under the drive of the two movable strips, the perforated plate rotates around the rotating rod as the center again. At this time, the perforated plate is located on the surface of the groove, which can push the seaweed and floating garbage in front of the boat body to both sides, preventing it from affecting the forward movement of the boat body, and also preventing seaweed from entering the propeller of the boat body and affecting its operation.

[0017] 2. In this embodiment of the invention, the cylinder rotates around the long rod 2 with the rectangular block as the center. At this time, the included angle between the cylinders is 90 degrees. At this time, the rotating threaded rod 3 moves inside the protrusion. At this time, the threaded rod 3 is embedded in the hole on the surface of the square groove to limit the cylinder. At this time, the support plate is supported on the ground and supports the upper feeding sliding mechanism. Pulling the horizontal bar, the hollow bar slides on the outer surface of the sliding bar. At the same time, the U-shaped plate 2 slides on the outer surface of the U-shaped plate 1. After sliding, the rotating threaded rod 2 moves inside the L-shaped plate 1. The threaded rod 2 is embedded in the inside of one of the locking holes to limit the locking hole. The photovoltaic panel is placed on the surface of the locking hole. The photovoltaic panel slides along the upper surface of the locking hole to the upper surface of the placement plate, which facilitates the transportation of the photovoltaic panel to the top of the placement plate.

[0018] 3. In this embodiment of the invention, by rotating the threaded rod one, the moving strip is pushed to slide inside the slide groove, at which time the photovoltaic panel is clamped and fixed to the upper surface of the placement plate.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 This embodiment provides a technical solution: a marine photovoltaic platform transfer device, comprising: a ship body 101, a connecting shaft 104 rotatably connected to the bottom of the ship body 101, reciprocating screws 103 fixedly connected to both ends of the connecting shaft 104, short rods 107 fixedly connected to opposite ends of the two reciprocating screws 103, rotating plates 102 fixedly connected to opposite ends of the two short rods 107, movable strips 105 slidably connected to the outer surfaces of the two reciprocating screws 103, elongated holes 108 formed on the outer surfaces of the two movable strips 105, limiting rods 106 fixedly installed at the bottom of the ship body 101, the two movable strips 105 sliding on the outer surfaces of the limiting rods 106, hollow frames 109 fixedly connected to one end of the two limiting rods 106, grooves 112 formed inside the two hollow frames 109, and two rotating rods 110 movably embedded in the inner walls of the two hollow frames 109.

[0031] In use, when the ship body 101 is transported in the water, it drives the rotating plate 102 to rotate. The rotating plate 102 drives the two reciprocating screws 103 to rotate through the connecting shaft 104. After the two reciprocating screws 103 rotate, they drive the two movable bars 105 to slide back and forth on their outer surface. The limiting rod 106 limits the two movable bars 105. When the two movable bars 105 are moving, they drive the two hollow frames 109 to move. At this time, when the two hollow frames 109 move towards the middle at the same time, the perforated plate 111 surrounds... The rotating rod 110 rotates around the center, at which time the hollow frame 109 is in the open state, reducing its resistance. When the two hollow frames 109 move in opposite directions simultaneously under the drive of the two movable bars 105, the perforated plate 111 rotates around the rotating rod 110 again. At this time, the perforated plate 111 is located on the surface of the groove 112, which can push the seaweed and floating garbage in front of the boat body 101 to both sides to prevent it from affecting the forward movement of the boat body, and at the same time prevent the seaweed from entering the propeller of the boat body and affecting its operation.

[0032] like Figures 1 to 8As shown, in one embodiment, a perforated plate 111 is movably fitted on the outer surface of a plurality of rotating rods 110. The plurality of perforated plates 111 are located on the outer surface of the groove 112. A placement plate 113 is fixedly connected to the top of the outer surface of the ship body 101. A threaded rod 114 is movably embedded on one side of the placement plate 113. One end of each of the two threaded rods 114 is connected to a moving strip 116 through a bearing. A plurality of sliding grooves 115 are opened on the inner wall of the placement plate 113. The plurality of sliding grooves 115 are evenly divided into two groups. The two moving strips 116 are slidably connected inside the two groups of sliding grooves 115. The photovoltaic panel is placed on the surface of the card hole 123. The photovoltaic panel slides along the upper surface of the card hole 123 and slides to the upper surface of the placement plate 113. Then, by rotating the threaded rod 114, the moving strip 116 is pushed to slide inside the sliding groove 115. At this time, the photovoltaic panel is clamped and fixed.

[0033] like Figures 1 to 8 As shown, in one embodiment, two fixing strips 117 are fixedly installed on the top of the outer surface of the placement plate 113. The two fixing strips 117 are respectively located on the parallel side of the two moving strips 116. A long rod 118 is movably embedded on one side of the placement plate 113. Two U-shaped plates 119 are movably sleeved on the outer surface of the long rod 118. U-shaped plates 120 are slidably connected to the outer surfaces of the two U-shaped plates 119. A horizontal bar 126 is fixedly connected to one end of the two U-shaped plates 120. The horizontal bar 126 is fixedly installed on the side of the two U-shaped plates 120. It is equipped with two hollow strips 124, and each hollow strip 124 has a sliding strip 125 movably fitted inside. Each of the two U-shaped plates 119 is fixedly connected to one side of an L-shaped plate 121. Rotating the threaded rod 131 disengages it from the hole on the surface of the rectangular block 128, and rotating the threaded rod 122 moves it inside the L-shaped plate 121. At this time, the threaded rod 122 disengages from the hole 123, the U-shaped plate 120 slides on the inner wall of the U-shaped plate 119, and the hollow strips 124 slide on the outer surface of the sliding strips 125, which allows for storage and reduces the volume.

[0034] like Figures 1 to 8As shown, in one embodiment, threaded rods 122 are movably embedded inside both L-shaped plates 121, and locking holes 123 are formed on the outer surfaces of both U-shaped plates 120, with the two threaded rods 122 movably embedded inside the two locking holes 123. One of the U-shaped plates 119 has a square groove 138 on its outer surface. The outer surface of the ship body 101 is connected to an L-shaped plate 133 by a long strip. A pull rod 136 is movably embedded inside the L-shaped plate 133. One end of the pull rod 136 is fixedly connected to a limiting block 134. A spring 135 is provided on one side of the limiting block 134. A locking block 137 is fixedly installed on the side of the limiting block 134 away from the spring 135. The locking block 137 is movably embedded inside the square groove 138. When the U-shaped plate 120 is rotated around the long rod 118, the pull rod 136 is pulled to move the limiting block 134. When the square groove 138 is parallel to the locking block 137, the locking block 137 is locked inside the square groove 138 by the limiting action of the sliding strip 125, thus limiting the entire feeding sliding mechanism.

[0035] like Figures 1 to 8 As shown, in one embodiment, a long rod 127 is movably embedded at the bottom of the horizontal bar 126. Two rectangular blocks 128 are movably fitted on the outer surface of the long rod 127. Cylinders 129 are fixedly connected to the bottom of the outer surfaces of the two rectangular blocks 128. Support plates 132 are fixedly connected to the bottom ends of the two cylinders 129. Two protrusions 130 are fixedly connected to the bottom of the horizontal bar 126 near the bottom of the two rectangular blocks 128. Threaded rods 131 are movably embedded inside the two protrusions 130. Each threaded rod 131 is movably embedded in the holes of the two rectangular blocks 128. The cylinder 129 rotates around the long rod 127 with the rectangular blocks 128 as the center. At this time, the included angle between the cylinders 129 and the cylinder 127 is 90 degrees. The threaded rod 131 moves inside the protrusion 130. The threaded rod 131 is then embedded in the hole on the surface of the square groove 138 to limit the cylinder 129. At this time, the support plate 132 is supported on the ground and supports the upper feeding sliding mechanism.

[0036] Working principle: During operation, cylinder 129 rotates around long rod 127 via rectangular block 128, with the angle between cylinder 129 and long rod 127 as the center. At this time, the angle between cylinder 129 and long rod 127 is 90 degrees. Simultaneously, threaded rod 131 moves inside protrusion 130, fitting into the hole on the surface of square groove 138 to limit cylinder 129. Support plate 132 supports the ground, supporting the upper feeding sliding mechanism and pulling horizontal bar 126. Hollow bar 124 slides on the outer surface of sliding bar 125, while U-shaped plate 120 slides on the outer surface of U-shaped plate 119. After sliding, threaded rod 122 moves inside L-shaped plate 121, fitting into the hole. The photovoltaic panel is positioned inside one of the slots 123, limiting its movement. It is then placed on the surface of the slot 123 and slides along its upper surface to the upper surface of the placement plate 113. Rotating the threaded rod 114 pushes the moving bar 116 to slide inside the groove 115, clamping and fixing the photovoltaic panel to the upper surface of the placement plate 113. Rotating the threaded rod 131 disengages it from the hole on the surface of the rectangular block 128, and rotating the threaded rod 122 moves it inside the L-shaped plate 121. At this point, the threaded rod 122 disengages from the slot 123, and the U-shaped plate 120 slides on the inner wall of the U-shaped plate 119. The hollow bar 124 moves outside the sliding bar 125. The surface sliding mechanism allows for storage and reduces volume. When the U-shaped plate 120 is rotated around the long rod 118, the pull rod 136 moves the limiting block 134. When the square groove 138 is parallel to the locking block 137, the locking block 137 is locked inside the square groove 138 by the limiting action of the sliding bar 125, thus limiting the entire feeding sliding mechanism. When the ship body 101 is transported in the water, it drives the rotating plate 102 to rotate. The rotating plate 102 drives the two reciprocating screws 103 to rotate via the connecting shaft 104. After the two reciprocating screws 103 rotate, they drive the two movable bars 105 to slide back and forth on their outer surface. The limiting rod 106 controls the two movable bars 105. 5. Limiting is performed. When the two movable bars 105 move, they drive the two hollow frames 109 to move. When the two hollow frames 109 move towards the middle at the same time, the perforated plate 111 rotates around the rotating rod 110 as the center. At this time, the middle of the hollow frame 109 is in an open state, reducing its resistance. When the two hollow frames 109 move in opposite directions at the same time under the drive of the two movable bars 105, the perforated plate 111 rotates around the rotating rod 110 as the center again. At this time, the perforated plate 111 is located on the surface of the groove 112, which can push the seaweed and floating garbage in front of the boat body 101 to both sides to prevent it from affecting the forward movement of the boat body, and at the same time prevent the seaweed from entering the propeller of the boat body and affecting its operation.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
