Description

Technical Field

[0001] The present invention relates to the technical field of marine photovoltaic power generation, and particularly relates to a double-rail sliding self-locking offshore photovoltaic structure and an installation method thereof. Background Art

[0002] However, compared with the gradually mature land photovoltaic power generation, offshore photovoltaic power generation is still in its infancy and faces many difficulties. Limited by the offshore operation space, workers cannot move freely between columns to install photovoltaic panels. Moreover, due to the height reserved for the influence of tides and waves in offshore photovoltaic power generation, workers cannot directly reach the installation height and need to move on the support structure or use a shipborne lifting device, which has a relatively high risk factor. Frequent use of ships not only increases the inefficient consumption of unnecessary human and material resources and delays the construction period, but also brings other risks such as the hull colliding with the support columns and the hull shaking affecting the workers' operations. At the same time, traditional fixed offshore photovoltaic power generation generally adopts rigid connections. To ensure its reliability during service, most of them increase the size of the support members to improve the installation strength of the photovoltaic panels and resist the instantaneous loads brought by wind and waves, resulting in poor economy.

[0003] Currently, Chinese Patent No. CN115864952B proposes a photovoltaic panel, a photovoltaic system and an installation method thereof, including a support frame, a photovoltaic panel body, a front end lock head and a rear end lock body fixed on the support frame, a sliding clamp and a slideway cooperating with the sliding clamp. The slideway is connected between the upper cross beam and the lower cross beam of the photovoltaic system, and the photovoltaic panel body is slidably installed on the slideway through the sliding clamp. During the installation process, the photovoltaic panel is lifted by a lifting device, and the photovoltaic panel is automatically slid and installed on the slideway through the lifting device to form a whole row of photovoltaic panels. Finally, a whole surface of photovoltaic panels is formed between the upper cross beam and the lower cross beam. Although the existing technical solution can complete the installation and fixation of large-area photovoltaic panels, it has the following deficiencies: 1. It has high requirements for the lifting height and span of the hoisting equipment, and medium and large-sized hoisting equipment is required for construction. At the same time, manual assistance is required to enter the area of the photovoltaic panels for installation; 2. The double-base column structure adopted has a large amount of steel used, complex construction and a long installation period; 3. The brackets of the offshore photovoltaic panels are fixed on the seabed in an array manner, and the distance between adjacent two rows of brackets is small. During the installation process, a small boat with auxiliary equipment needs to enter between the two rows of brackets for operation, which is inconvenient and cumbersome to operate. It is difficult to operate the auxiliary equipment in the limited space, resulting in low installation efficiency and poor safety. Due to the limited and unstable working surface of the offshore photovoltaic panels, the above invention cannot be used as a reference for the installation of fixed offshore photovoltaic power generation. Therefore, it is necessary to design an installation structure and method for offshore array photovoltaic panels to solve the problems of cumbersome installation, low efficiency and large amount of steel used in the structure of fixed offshore photovoltaic power generation.

[0026] Another object of the present invention is to provide a method for installing a double-track sliding self-locking offshore photovoltaic structure.

[0027] A method for installing a double-track sliding self-locking offshore photovoltaic structure, based on the above-mentioned double-track sliding self-locking offshore photovoltaic structure, the installation method comprises the following steps:

[0028] S1. Use a transport ship to transport the steel piles to the predetermined installation area, and fix the steel piles on the seabed in sequence. The top height of each steel pile is consistent and higher than the set height of the sea surface. The steel piles in the same group are arranged in a straight line with equal intervals.

[0029] The first bracket is fixedly installed on the upper ends of the first and last steel piles so that the heights of the two first brackets are consistent, and the second bracket is fixedly installed on the upper ends of the steel piles in the middle positions.

[0030] S2. Pulley assemblies are installed at the front and rear ends of the two first brackets respectively, and a ring-shaped steel cable is installed on each pulley assembly.

[0031] The driving device and the battery are installed on the first bracket on the right side. The two output ends of the driving device are respectively connected to the active pulleys of the two pulley assemblies. The battery is electrically connected to the driving device. The driving device is started to debug the synchronization of the movement of the two circular steel cables.

[0032] S3. The transport ship docks at the left side of the first steel pile, and the first photovoltaic panel is placed on top of the two circular steel cables. The roller assemblies at the bottom of the photovoltaic panel are connected to the corresponding circular steel cables, so that the roller assemblies and the circular steel cables can roll together. After that, adjust the four pairs of jaws under the photovoltaic panel so that each pair of jaws clamps the corresponding circular steel cables.

[0033] S4. Turn on the driving device. The two circular steel cables move synchronously to drive the first photovoltaic panel to move to the right. When the first photovoltaic panel reaches the first bracket on the right, the left ends of the two self-locking rods installed on the first bracket on the right respectively penetrate into the installation cavity on the right side of the first photovoltaic panel. The elastic claws on the outside of the self-locking rods clamp the inner wall of the stepped hole and are fixedly connected to the first photovoltaic panel.

[0034] When the self-locking rod enters the installation cavity, its left end passes between the two sliders, and the self-locking rod pushes the two sliders to the side away from each other, so that the clamp is separated from the ring steel cable and maintains this state. After the installation of the first photovoltaic panel is completed, the ring steel cable stops moving.

[0035] S5. Place the second photovoltaic panel above the two circular steel cables, repeat steps S3 and S4 to securely connect the second photovoltaic panel to the first photovoltaic panel, and complete the installation of the remaining photovoltaic panels in sequence.

[0036] Afterwards, a U-shaped lock is installed on the upper part of the circular steel cable, and the U-shaped lock limits the roller assembly under the leftmost photovoltaic panel.

[0037] By adopting the above technical scheme, the beneficial technical effect of the present invention is as follows: the present invention installs the photovoltaic panels from one side of the working area through the annular steel cable and pulley assembly arranged on the bracket, and the boat carrying the photovoltaic panels docks at one end of each row of brackets, and the photovoltaic panels are placed one by one on the annular steel cable, so that the photovoltaic panels can be quickly installed with high stability, without the need for the assistance of lifting equipment, and the boat does not need to enter between the two rows of brackets, so the operation is highly safe, the installation cost is low and the efficiency is high, and the construction period is shortened.

There are multiple steel piles 1, and all the steel piles 1 are arranged in a row at equal intervals from left to right. Each steel pile 1 is vertically arranged and the lower end is fixed to the seabed. In the photovoltaic panel installation area of the ocean, multiple rows of steel piles 1 are arranged at equal intervals from front to back, forming a square area on the sea surface.

[0049] A first bracket 11 is provided at the upper end of the first and last steel piles 1 of each row of steel piles 1. The first bracket 11 includes an I-beam 111 and a first clamp 112. The I-beam 111 is fixedly connected to the first clamp 112 through a support rod group to form a triangular first bracket 11. Specifically, the first clamp 112 is fixedly sleeved on the upper end of the first or last steel pile 1. The I-beam 111 is arranged in an inclined manner with the front lower and the rear higher, and is fixedly connected to the first clamp 112 through a support rod group. The first bracket 11 is fixedly connected to the upper end of the first or last steel pile 1 through the first clamp 112.

[0050] The upper end of the steel pile 1 in the middle position is provided with a second bracket 13, and the second bracket 13 includes a longitudinal beam 131 and a second hoop 132. The longitudinal beam 131 is fixedly connected to the second bracket 13 in a triangle through the same support rod group and the second hoop 132. The second hoop 132 has the same structure as the first hoop 112. The second hoop 132 is fixedly sleeved on the upper end of the steel pile 1 in the middle position. The longitudinal beam 131 preferably adopts a section of square tube. The longitudinal beam 131 is arranged relatively parallel to the I-beam 111 and is fixedly connected to the second hoop 132 using the same support rod group. The second bracket 13 is fixedly connected to the upper end of the steel pile 1 in the middle position through the second hoop 132.

[0051] There are two pulley assemblies, which are respectively arranged on the front and rear sides of the first bracket 11 and the second bracket 13. Specifically, the pulley assembly includes an active pulley 41 and a driven pulley 42. The driven pulley 42 is installed on the left side of the first bracket 11 above the first steel pile 1, and the active pulley 41 is installed on the right side of the first bracket 11 above the last steel pile 1. The installation method and structure of the two pulley assemblies are the same. The two active pulleys 41 and the two driven pulleys 42 are respectively located on the side of the two first brackets 11 that are away from each other. The axles of the active pulley 41 and the axles of the driven pulley 42 are respectively installed on the adjacent first bracket 11 through a bearing seat. The active pulley 41 and the driven pulley 42 can rotate relative to the adjacent first bracket 11. The two bearing seats matched with the active pulley 41 are installed on the first bracket 11 through a tensioning mechanism. The tensioning mechanism adopts the tensioning mechanism already available in the prior art.

[0052] Each pulley assembly is provided with an annular steel cable 2, which is arranged outside the active pulley 41 and the driven pulley 42 and is located in the groove of the circumferential outer wall of the active pulley 41 and the driven pulley 42. The I-beam 111 is provided with a through hole for the annular steel cable 2 to pass through. After the annular steel cable 2 is installed, it is in a tensioned state, and the active pulley 41 drives the corresponding driven pulley 42 to rotate through the annular steel cable 2.

[0053] On each of the second brackets 13, there are two wire assemblies respectively corresponding to the position of the annular steel cable 2. The wire assembly includes a wire support base 43 and a wire conduit 44. The wire support base 43 is fixedly installed on the top of the second bracket 13. The top of the wire support base 43 has a through groove opened horizontally. The bottom of the through groove is an arc-shaped surface that is high in the middle and low at both left and right ends. The upper part of the annular steel cable 2 is located inside the through groove. The wire support base 43 supports the upper part of the annular steel cable 2. In addition, the front and rear sides of the wire support base 43 restrain the annular steel cable 2 to prevent the upper part of the annular steel cable 2 from slipping out of the wire support base 43. The wire conduit 44 is arranged directly below the wire support base 43, and the lower part of the annular steel cable 2 passes through the inside of the wire conduit 44.

[0054] The driving device is arranged on the first bracket 11 on the right side, and its execution end drives the two annular steel cables 2 to move synchronously through a pulley assembly. The driving device is arranged on the first bracket 11 on the right side and includes a double-output shaft servo motor 51 and a bevel gear assembly. The output shafts of the double-output shaft servo motor 51 are arranged vertically. There are two bevel gear assemblies, which are respectively arranged on the upper and lower sides of the double-output shaft servo motor 51. A storage battery is installed on the first bracket 11 on the right side, and the storage battery supplies power to the double-output shaft servo motor 51; alternatively, the wiring terminals of the double-output shaft servo motor 51 can also be connected to the power supply system of the transport ship, and the power supply system of the transport ship supplies power to the double-output shaft servo motor 51.

[0055] The bevel gear assembly includes a driving bevel gear 52 and a driven bevel gear. The two output shafts of the double-output shaft servo motor 51 are arranged vertically. The axles of the two driving bevel gears 52 are respectively coaxially and fixedly connected to the two output shafts of the double-output shaft servo motor 51. The axles of the two driven bevel gears are respectively coaxially and fixedly connected to the two driving pulleys 41. The driving bevel gear 52 located above the double-output shaft servo motor 51 meshes with the driven bevel gear connected to the rear driving pulley 41, and the driving bevel gear 52 located below the double-output shaft servo motor 51 meshes with the driven bevel gear connected to the front driving pulley 41.

[0056] During the installation process of the photovoltaic panel, the double-output shaft servo motor 51 drives the two driving pulleys 41 to rotate synchronously through the bevel gear assembly. The driving pulleys 41 drive the two annular steel cables 2 to move in the same direction and synchronously, and drive the photovoltaic panel 3 arranged above the two annular steel cables 2 to be able to move from left to right.

[0057] There are multiple photovoltaic panels 3, and all the photovoltaic panels 3 are arranged adjacent to each other in sequence from left to right above the two annular steel cables 2. The photovoltaic panel 3 includes a square frame body and a photovoltaic panel body located inside the frame body. On the front and rear sides of the bottom of each photovoltaic panel 3, there are two roller assemblies respectively. The two roller assemblies on the same side are all in rolling cooperation with the corresponding annular steel cable 2.

[0058] Specifically, the roller assembly includes a mounting plate 61, an upper roller 62, and a lower roller 63. The mounting plate 61 is fixed to the bottom of the photovoltaic panel 3 by bolts.

Two insertion openings are respectively provided on both sides of the lower end of the H-shaped frame 64, and square openings for cooperating with elastic hooks are provided on its side walls. A pair of elastic hooks 651 are respectively provided on both sides of the upper end part of the U-shaped frame 65. The two sides of the upper end part of the U-shaped frame 65 can be respectively inserted into the two insertion openings at the lower end of the H-shaped frame 64. The U-shaped frame 65 and the H-shaped frame 64 are in a separated state before installation.

[0060] During the installation process, first place the photovoltaic panel 3 above the two annular steel cables 2, so that the two upper rollers 62 on the front side of its bottom are located on the front annular steel cable 2, and the two upper rollers 62 on the rear side of the bottom are located on the rear annular steel cable 2. The annular steel cable 2 is located in the groove of the upper roller 62, and the upper roller 62 can roll left and right along the upper part of the annular steel cable 2. Then, install a U-shaped frame 65 with a lower roller 63 below each H-shaped frame 64. The upper end of the U-shaped frame 65 is plug-in and fixedly connected to the lower end of the H-shaped frame 64. The lower roller 63 is located at the bottom of the annular steel cable 2 and is in rolling cooperation with the annular steel cable 2, locking the photovoltaic panel 3 on the two annular steel cables 2. Under the action of wind force, the photovoltaic panel 3 will not be disengaged from the annular steel cable 2 in a tensioned state.

[0061] An installation seat 12 is provided on the first support 11 on the right side. The installation seat 12 is connected to the first photovoltaic panel 3 through two self-locking mechanisms arranged one in front and one behind. Any two adjacent photovoltaic panels 3 are connected through the same two self-locking mechanisms.

[0062] Specifically, there are two installation cavities 31 inside the right side of the frame of the photovoltaic panel 3. The two installation cavities 31 are respectively located at the front and rear ends of the frame of the photovoltaic panel 3, and correspond to the positions of the two self-locking rods 71 on the left side of the installation seat 12 one by one. The installation cavity 31 is a rectangular cavity, and its bottom has two square openings arranged one in front and one behind. The self-locking mechanism includes a self-locking rod 71 and two sliders 72. The self-locking rod 71 of the self-locking mechanism between the installation seat 12 and the first photovoltaic panel 3 is arranged on the left side of the installation seat 12, and the self-locking rod 71 of the self-locking mechanism between any two adjacent photovoltaic panels 3 is arranged on the left side of the right photovoltaic panel 3.

The two clamping claws 74 are arranged front and back oppositely, and the two clamping claws 74 can hold the corresponding annular steel cable 2. The left and right side walls of the installation cavity 31 are each provided with two sections of slide grooves, and the two sections of the slide grooves on the same side are arranged one front and one rear at intervals. The left and right sides of the slider 72 are located in the slide grooves and slide with the side walls of the installation cavity 31 front and back.

[0064] A spring 73 is provided on each side of the two sliders 72 facing away from each other. One end of the spring 73 is connected to the side wall of the slider 72, and the other end is connected to the side wall of the installation cavity 31. The side walls of the two sliders 72 that are close to each other are provided with a first arc groove 721. The two first arc grooves 721 are arranged relative to each other in front and back, and the right end adopts a chamfered structure. The spring 73 is in a compressed state in a natural state, and there is a gap between the two sliders 72, which facilitates the self-locking rod 71 to penetrate between the two sliders 72. During the installation process, when the annular steel cable 2 drives the photovoltaic panel 3 to move rightward to the installation position, the two self-locking rods 71 ​​located on the right side of the photovoltaic panel 3 penetrate into the installation cavity 31 of the photovoltaic panel 3, enter between the two sliders 72 and open the two sliders 72, and drive the two clamping claws 74 below them to open and separate from the annular steel cable 2.

[0065] The upper ends of the two clamping jaws 74 are respectively fixedly connected to the bottoms of the two sliders 72 above them, and the sides of the lower ends of the two clamping jaws 74 that are close to each other are each provided with a second arc groove 741. The two second arc grooves 741 are arranged front and back relative to each other, and the inner side walls of the second arc grooves 741 are provided with a rubber anti-skid layer. During the installation process, after the roller assembly and the annular steel cable 2 at the bottom of the photovoltaic panel 3 are installed, the positions of the two clamping jaws 74 are manually adjusted, and the lower ends of the two clamping jaws 74 are clamped to the outer wall of the annular steel cable 2 under the action of the spring 73. The annular steel cable 2 is located in the two second arc grooves 741, so that the photovoltaic panel 3 is fixed on the annular steel cable 2, and the two annular steel cables 2 drive the photovoltaic panel 3 to move rightward from the first bracket 11 on the left.

[0066] A stepped hole 32 is provided on the right side of the installation cavity 31. The stepped hole 32 is a two-step stepped hole 32. The inner diameter of the left part is larger than the inner diameter of the right part. The right end of the stepped hole 32 is in a trumpet shape.

[0070] S1. Use a transport ship to transport the steel piles 1 to the predetermined installation area, and fix the steel piles 1 on the seabed in sequence. The upper ends of the steel piles 1 have the same height and are higher than the set height of the sea surface. The steel piles 1 in the same group are arranged in a straight line with equal intervals.

[0071] The first bracket 11 is fixedly installed on the upper ends of the first and last steel piles 1 so that the heights of the two first brackets 11 are consistent, and the second bracket 13 is fixedly installed on the upper ends of the steel piles 1 in the middle positions.

[0072] S2. Pulley assemblies are installed at the front and rear ends of the two first brackets 11 respectively, and a ring-shaped steel cable 2 is installed on each pulley assembly.

[0073] The driving device and the battery are installed on the first bracket 11 on the right side.

The driving device is started to debug the synchronization of the movement of the two circular steel cables 2.

[0074] S3. The transport ship docks at the left side of the first steel pile 1, and the first photovoltaic panel 3 is placed above the two circular steel cables 2. The roller assemblies at the bottom of the photovoltaic panel 3 are connected to the corresponding circular steel cables 2, so that the roller assemblies and the circular steel cables 2 are rollingly matched. Afterwards, the four pairs of jaws 74 under the photovoltaic panel 3 are adjusted so that each pair of jaws 74 clamps the corresponding circular steel cables 2.

[0075] S4. Turn on the driving device. The two annular steel cables 2 move synchronously to drive the first photovoltaic panel 3 to move to the right.

[0076] When the self-locking rod 71 enters the installation cavity 31, its left end passes between the two sliders 72, and the self-locking rod 71 pushes the two sliders 72 to the side away from each other, so that the clamp 74 is separated from the annular steel cable 2 and maintains this state. After the installation of the first photovoltaic panel 3 is completed, the annular steel cable 2 stops moving.

[0077] S5. Place the second photovoltaic panel 3 above the two circular steel cables 2, repeat steps S3 and S4 to securely connect the second photovoltaic panel 3 to the first photovoltaic panel 3, and complete the installation of the remaining photovoltaic panels 3 in sequence.

[0078] Afterwards, a U-shaped lock is installed on the upper part of the circular steel cable 2. The U-shaped lock limits the roller assembly under the leftmost photovoltaic panel 3 to prevent the upper roller 62 under the photovoltaic panel from moving along the circular steel cable 2 under the action of external force, thereby improving the stability and reliability of the photovoltaic panel 3 after installation.
