Description

Technical Field

[0001] This invention relates to a floating device for installing photovoltaic modules, belonging to the field of floating photovoltaic technology. Background Technology

[0002] With land-based photovoltaic (PV) installations reaching saturation, floating PV modules are becoming a trend. Floating PV power stations offer ample installation space, occupying no land and not impacting aquatic life. However, water surface fluctuations can cause PV modules to drift and collide, reducing their lifespan. For example, Chinese Patent Publication No. CN221214511U, "A Floating PV Support," describes a PV support frame with a support structure on top of the pontoons, connecting adjacent pontoons via connecting components. While these components prevent collisions between adjacent pontoons, they also create large gaps between them, allowing cables to run overhead. This prevents the pontoons from forming a cohesive unit to withstand wave impacts and can easily lead to the failure of connecting components. Furthermore, the turbulent movement of the pontoons increases the uncertainty of their position, affecting power generation efficiency. Moreover, currently, floating PV power stations are relatively expensive. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of current floating bodies being unable to be connected into a single sheet and having poor stability, while also addressing the high costs caused by inconvenient transportation and installation.

[0004] To achieve the above objectives, the specific technical solution adopted by the present invention is as follows:

[0005] A floating device for installing photovoltaic modules, characterized in that the floating device includes a floating body and a folding bracket, and also includes photovoltaic modules, connecting ropes, and elastic open clamps connecting the floating bodies.

[0006] The floating body is made of foam material. The front and rear of the floating body (in the direction of water flow) are provided with connecting shafts. The connecting shafts connect the front and rear floating bodies with open clamps. The left and right sides are provided with mortise and tenon structures to connect the left and right floating bodies into a whole to resist the impact of water waves. The bottom of the floating body is provided with bamboo raft through holes in the direction of water flow to reduce weight, increase buoyancy, and increase stability. The left and right mortise and tenon structures of the floating body are provided with rope through holes to pass through connecting ropes. The middle position of the top of the floating body is provided with a sinking surface for installing a folding bracket and placing photovoltaic modules inside. The upper side is provided with a wire groove for arranging cables.

[0007] The folding bracket consists of a base, a lower rod, an upper rod, a connecting seat, and a mounting seat. The base is embedded in the floating body. The lower end of the lower rod is rotatably connected to the base by bolts and can be tightened. The upper ends of the lower rod and the lower ends of the upper rod are rotatably connected to the connecting seat by bolts and can be tightened. The upper end of the upper rod is rotatably connected to the mounting seat by bolts and can be tightened. Photovoltaic modules are installed on the mounting seat by pressure blocks or bolts. The folding bracket includes four sets: front, back, left, and right. The front and back folding brackets are installed symmetrically. The length of the upper rod of the front folding bracket is less than the length of the upper rod of the front folding bracket, forming an angle for installing photovoltaic modules. The length difference is determined according to different geographical locations.

[0008] The connecting rope is divided into multiple interconnected segments that can be detached;

[0009] The elastic opening clips are used in pairs, with the two opening clips connected by an elastic rubber rod, allowing them to float with the waves.

[0010] The bamboo raft has a conical through-hole, a large-diameter inlet, and a small-diameter outlet. An impeller for a water turbine generator is installed on the outlet, and the turbine generates electricity by rotating.

[0011] During installation, first connect the left and right floating bodies one by one with mortise and tenon joints, and pass the rope through the rope through hole. Then connect the front and rear floating bodies with open clamps, and pass the rope through the rope through hole to form a whole area. Pull the photovoltaic module from the floating body and fold the bracket from the horizontal position to the vertical position, tighten it with bolts, connect the series and parallel wires, and then arrange the cables in the wire trough and cover the wire trough.

[0012] The left and right tenon and mortise structures are several, one of which is equipped with an upper movable block. The upper movable block is separated from the middle of the rope through hole. Below the upper movable block is a conical insert that is inserted into the conical hole on the corresponding lower fixed block. When maintenance is required, the upper movable block is opened, the rope joint is separated, a section of rope is taken out, and the float can be replaced.

[0013] The mortise and tenon structure or the floating body is a separate embedded structure. It can be manufactured separately and then the protruding mortise and tenon structure is embedded into the floating body to become a whole.

[0014] The bottom surface of the floating body is streamlined to facilitate water flow.

[0015] The rope-threading hole is lined with a liner made of polymer material or stainless steel.

[0016] The upper end of the base is semi-circular, with a bolt connection hole at the center of the semi-circle, and the lower end is a flange seat, which is embedded and fixed on the floating body.

[0017] The lower rod is made of channel steel, and a baffle is provided at the lower end of the lower rod. When pulled up, it is limited to the side of the base. The lower end of the lower rod is also provided with a bolt connection hole for connecting with the base. The upper end of the lower rod is semi-circular, and a bolt connection hole is opened at the center of the semi-circle.

[0018] The upper rod is made of channel steel, with both ends being semi-circular, and bolt connection holes are opened at the center of the semi-circles.

[0019] The connecting seat is made of channel steel and has bolt holes for connecting to the upper and lower rods.

[0020] The mounting base is a channel steel with bolt holes on the side for connecting to the upper rod and bolt holes on the top surface for fixing to the side frame of the photovoltaic module.

[0021] The positive and beneficial effects of this invention are as follows: the floating body is connected into a whole by ropes through a tenon and mortise structure, which has strong resistance to wind and waves and high stability. The photovoltaic modules can be placed flat inside the floating body, which is convenient for transportation. The overall structure is lightweight, has great buoyancy, and is easy to install and maintain. Attached Figure Description

Detailed Implementation

[0029] As shown in the figure, the floating body 1 is made of foamed material. The left and right sides of the floating body 1 have a tenon-and-mortise structure 104 composed of multiple alternating ridges on one side and corresponding alternating ridges on the other. The front and rear sides of the floating body 1 have a connecting shaft 105 with grooves. The connecting shaft 105 is held by elastic open clamps 5, and the two elastic open clamps 5 are connected by elastic rubber rods 6. The bottom of the floating body 1 has a bamboo raft through-hole 102 in the direction of water flow. The outlet of the bamboo raft through-hole 102 is fitted with the impeller of a water turbine generator. The left and right tenon-and-mortise structures 104 of the floating body 1 have rope-threading through-holes 103. An upper movable block 104-1 and a lower fixed block 104-2 are set on a protruding ridge of the left and right mortise and tenon structure 104. The upper movable block 104-1 is separated from the middle of the rope through hole 103. A conical insert 104-1-1 is set below the upper movable block 104-1 and inserted into the conical slot of the lower fixed block 104-2. A sinking surface 101 is set at the middle position of the upper part of the float 1. A folding bracket 2 is installed in the sinking surface 101. The folding bracket 2 is composed of a base 201, a lower rod 202, an upper rod 203, a connecting seat 204, and a mounting seat 205. The flange seat 201-1 of 01 is embedded in the floating body 1. The base connecting bolt hole 201-2 and the lower rod bolt connecting hole 202-3 at the lower end of the lower rod 202 are connected by bolts and tightened. The lower end of the lower rod 201 is also provided with a lower end baffle 202-1, which limits the lower rod to the vertical side of the base 201 after it is extended and cannot rotate. The upper end of the lower rod 202 and the lower end of the upper rod 203 are connected by connecting seat 204 through the lower rod bolt connecting hole 202-3 and the upper rod bolt hole 203-2 corresponding to the connecting seat bolt connecting hole 204-1, and are connected by bolts and tightened. To avoid affecting rotation, the upper rod 203 is made into a semi-circular shape at both ends 203-1 and the lower rod 202 is made into a semi-circular shape at the top end 202-2. The bolt connection hole 205-1 on the upper end of the upper rod 203 and the side of the mounting base 205 is connected by bolts and tightened. The top surface of the mounting base 205 is provided with a photovoltaic module bolt connection hole 205-2 for connecting with the photovoltaic module 3. There are four sets of folding brackets 2. The front and rear folding brackets 2 are installed symmetrically. The upper rod 203 of the front folding bracket 2 is shorter than the upper rod 203 of the rear folding bracket, forming the installation tilt angle of the photovoltaic module 3.

[0030] During transportation, the photovoltaic module 3 is placed flat into the sinking surface 101 of the floating body 1 using the folding bracket 2, and is not higher than the upper surface of the floating body 1.

[0031] During installation, first connect the left and right tenon structures 104 of the floating body 1 one by one with tenons and mortises, and pass the rope 4 through the rope through hole 103. Then connect the connecting shaft 105 of the floating body 1 row by row with elastic open clamps 5, and pass the rope 4 through the rope through hole 103 to form a whole area. Pull the photovoltaic module 3 from the floating body 1 and fold the bracket 2 from the horizontal position to the vertical position, tighten it with bolts, connect the wires in series and parallel, and arrange the cables in the wire groove 106. Then cover the wire groove with the cover.

[0032] When a float 1 is damaged and needs to be replaced, remove the upper movable block 104-1. The rope 3 inside the upper movable block 104-1 has a connector. Loosen the elastic opening clamp, untie the rope 4 and pull it out. Take out the float 1 from the top for replacement. After replacement, pass the rope 3 through and put the upper movable block 104-1 back on to complete the replacement work.

[0033] In use, depending on the needs and installation power, it can be divided into several integrally connected floating bodies, and then these integrally connected floating bodies can be connected by certain means, which can be done using known technologies.
