Description

Technical Field

[0001] The present invention relates to the technical field of supporting floating platforms, in particular to a supporting floating platform for water photovoltaic power generation. Background Art

[0002] In addition to building photovoltaic power stations on the ground, building water power stations is also a feasible way for photovoltaic power generation. However, the current construction situation of water power stations is that most of the water surface resources are idle, so building photovoltaic power stations on the water surface is a trend.

[0003] The existing Chinese patent with publication number CN105227070A discloses a foundation for an aquatic photovoltaic power generation device, which includes a foundation arranged on water and a photovoltaic bracket on the foundation. The foundation includes a photovoltaic bracket support unit, which is used to fix and install the support column of the photovoltaic bracket on the foundation. The support column of the photovoltaic bracket is arranged on the photovoltaic bracket support unit.

[0004] Regarding the relevant technologies in the above-mentioned patents, the inventors believe that the supporting buoy used in the above-mentioned water photovoltaic power generation equipment is composed of multiple buoys connected to each other. This usage is limited by the structure of the buoys, and the support angle cannot be adjusted as needed during use. Moreover, the overall safety of the connection method using multiple buoys is poor. Once one of them is damaged, the entire supporting buoy will be at risk of falling apart. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a floating platform for water photovoltaic power generation.

[0006] The technical solution adopted by the present invention to solve the above-mentioned problem is: a supporting floating platform for water photovoltaic power generation, including a central frame, a buoyancy box and a bracket, characterized in that: the central frame includes a cross tube group and a movable side arm, the movable side arm is arranged at the end of the cross tube group, and the movable side arm is slidingly connected to the cross tube group, the buoyancy box is installed at the end of the movable side arm, and the buoyancy box is fixedly connected to the movable side arm by bolts, and the bracket is vertically installed on the movable side arm, and the bracket is fixedly connected to the movable side arm.

[0007] By adopting the above technical solution, when it is needed, the movable side arm can be installed through the cross tube group to ensure that the movable side arm can slide flexibly on the cross tube group, so as to facilitate the adjustment of the extension length of the movable side arm according to actual needs. After the adjustment of the movable side arm is completed, the buoyancy box can be installed to ensure that the center frame is supported by the buoyancy box and that the center frame can be stably placed on the water surface. After the center frame is stably placed on the water surface, the bracket can be used to support and connect the support frame at the lower end of the photovoltaic power generation. At the same time, the bracket can adjust its position on the movable side arm to achieve different support heights.

[0008] Furthermore, the cross tube group includes a positioning block and side tubes, the side tubes are evenly distributed on the outer surface of the positioning block, and the side tubes and the positioning block are integrally formed; the lower end surface of the positioning block is installed with a threaded sleeve, and the threaded sleeve is vertically fixedly connected to the lower end surface of the positioning block.

[0009] By adopting the above technical solution, when the cross tube group needs to be used, the side tube can be fixedly installed through the positioning block to ensure that the side tube is installed and coordinated with the movable side arm, and the movable side arm can be slid and adjusted inside the side tube. After adjusting the appropriate length, it can be locked by the locking bolt. At the same time, by installing a threaded sleeve on the lower end face of the positioning block, it is convenient to install the anti-sway mechanism through the threaded sleeve for use.

[0010] Furthermore, an anti-sway mechanism is installed at the lower end of the cross tube group, and the anti-sway mechanism includes a top plate, a vertical rod and a counterweight ball. The vertical rod is fixedly installed in the middle of the lower end surface of the top plate, and the counterweight ball is fixedly installed at the lower end of the vertical rod. The upper end surface of the top plate is provided with a threaded rod that cooperates with the threaded sleeve, and the threaded rod is formed integrally with the top plate.

[0011] By adopting the above technical solution, when the anti-sway mechanism needs to be installed, it can be installed in the threaded sleeve through the threaded rod on the top plate. This can ensure that the vertical rod together with the counterweight ball can be stably installed at the lower end of the positioning block to assist the positioning block to be more stable on the water surface.

[0012] Furthermore, the movable side arm includes a pull rod and an I-shaped frame. The pull rod is slidably installed in the side tube, and the end of the side tube is also equipped with a locking bolt for locking the pull rod. The I-shaped frame is installed at one end of the pull rod, and the I-shaped frame and the pull rod are formed integrally.

[0013] By adopting the above technical solution, when the movable side arm needs to be used, the buoyancy box and the bracket can be installed by pulling out the I-shaped frame on the pull rod for use.

[0014] Furthermore, the buoyancy tank includes a protective frame, a stand assembly and a tank shell. The stand assembly is vertically fixed to the upper end surface of the protective frame, and the tank shell is fixedly installed inside the protective frame.

[0015] By adopting the above technical solution, when the buoyancy box needs to be used, it can be surrounded by a protective frame on the outside of the box shell, so that the box shell can be protected to prevent objects on the water surface from colliding with the box shell during use. At the same time, the setting of the stand group can ensure better coordination and connection with the I-frame.

[0016] Furthermore, the stand group includes a stand plate and a turntable frame, a collar is provided in the middle of the stand plate, the collar and the stand plate are integrally formed, the turntable frame is rotatably installed in the collar, and a connecting hole is provided on the turntable frame, and reinforcing plates connected to the protective frame are symmetrically provided on the side of the stand plate.

[0017] By adopting the above technical solution, when the stand group needs to be used, the turntable frame can be installed through the ring on the vertical plate, so that the turntable frame can be rotated and installed in the middle of the vertical plate. In this way, when the turntable frame is connected to the I-shaped frame, the box shell can provide stable support for the center frame. When the box shell shakes with the water surface, the center frame does not rotate synchronously with it, thereby achieving the purpose of increasing the stability of the center frame during use. The setting of the reinforcement plate ensures that the stand group is more stable during use.

[0018] Furthermore, the side surface of the I-shaped frame is provided with side holes corresponding to the connection holes, and the I-shaped frame is also symmetrically provided with vertical holes for mounting the brackets.

[0019] By adopting the above technical solution, when the I-frame needs to be connected to the turntable frame, a bolt can be passed through one end of the connecting hole and then connected to the side hole. At the same time, the vertical hole is set to facilitate better installation and adjustment of the vertical screw.

[0020] Furthermore, the bracket includes a bent plate and a concave frame, the concave frame is connected to the upper end surface of the bent plate, and the concave frame and the bent plate are formed in one piece.

[0021] By adopting the above technical solution, when the bracket needs to be used, the concave frame can be installed through the bent plate, ensuring that the concave frame can be matched and connected with the external photovoltaic panel support frame when in use.

[0022] Furthermore, two vertical screws are symmetrically provided on the lower end surface of the bending plate. The vertical screws are vertically fixedly connected to the lower end surface of the bending plate, and a limiting nut is provided in the middle of the vertical screws.

[0023] By adopting the above technical solution, after the bent plate is installed in the vertical hole through the vertical screw, the vertical screw and the I-frame can be fixed to each other through the upper and lower limit nuts.

[0024] Compared with the prior art, the present invention has the following advantages and effects:

[0025] 1. The present invention has an anti-sway mechanism, which is used to stabilize the center frame, ensuring that the center frame can stably support the bracket, thereby achieving the purpose of stably supporting the photovoltaic panel through the bracket.

[0026] 2. The bracket of the present invention can adjust the position of the limit nut on the vertical screw during installation, thereby changing the support height of the bracket to meet different usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS
