Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic power generation, and particularly to a module sliding installation structure and a usage method for offshore suspension photovoltaic. Background Art

[0002] As more and more coastal provinces in China turn their attention to the ocean in the photovoltaic power generation market, offshore photovoltaic power generation, as a new field, has a broad market. How to achieve safe, economical and reliable installation of offshore photovoltaic structures has become one of the key technologies restricting the development of offshore photovoltaics.

[0003] The existing technologies close to the present invention are the manual installation technology of flexible support components and the construction cable hoisting installation technology of offshore suspension photovoltaics. The manual installation technology of flexible support components is to manually transport individual photovoltaic modules to the cable structure. The installation workers simultaneously rise to the installation position with the help of scaffolding or a scissor lift, and then manually install and fix the module to the cable structure. The construction cable hoisting installation technology of offshore suspension photovoltaics is to set a cable crane on the construction cable, transport the module to the lower part of the installation position by ship, the cable crane hoists the module to the installation position, the installation workers reach the installation position by means of a pedestrian cable, and then manually install and fix the module to the cable structure. The traditional installation technologies have the following defects:

[0004] (1) Whether it is the manual installation technology of flexible support components or the construction cable hoisting installation technology of offshore suspension photovoltaics, the installation workers need to reach the installation position and then manually install and fix the module to the cable structure. The manual installation method has low efficiency, poor safety and high installation costs.

[0005] (2) The manual installation technology requires manual transportation of components, which is difficult, costly and has a high safety risk in offshore operations and is not feasible; although the construction cable hoisting installation technology can use a cable crane for hoisting, the transport ship needs to reach the lower part of the installation position. In this way, the transport ship needs to be continuously displaced during the installation process, and the displacement of the transport ship needs to be achieved by winching the anchor. However, there are many piles and the pile positions are dense in the offshore photovoltaic field area, and the displacement operation of the transport ship is difficult and time-consuming, resulting in low installation efficiency.

[0010] Furthermore: A spring is connected and arranged on the inner side wall of the cavity. The spring is located between the inner side wall of the cavity and the upper pressing block, and an electric door is arranged at the outlet position of the cavity.

[0011] Furthermore: A telescopic motor is arranged in the groove, and the telescopic motor is connected to the electric bolt fastener. The bolt is arranged on the photovoltaic bracket, and a connection hole for the bolt to pass through is formed through the upper pressing block. The electric bolt fastener can cooperate with the bolt, so that the upper pressing block is fixed through the bolt when connected to the photovoltaic bracket.

[0012] Furthermore: The power lifting device includes a cable and a winch. The winch is installed in the sliding installation trolley. One end of the cable is connected to the winch, and the other end extends out of the sliding installation trolley and is connected to the photovoltaic bracket.

The pin column is connected to the hanging plate, and an upper pin column is arranged on the part of the pin column extending above the hanging plate. The sliding cable support is sleeved on the upper pin column.

[0014] Further: a pillar hanging plate is arranged on the outer surface of the sliding cable pillar, and the pillar hanging plate is connected to the sliding cable.

[0015] Further: the distance between adjacent sliding cables is greater than the distance between adjacent load-bearing cables, so as to facilitate the operation of the photovoltaic module.

[0016] The second object of the present invention is to provide a use method with fast and efficient, good safety and low installation cost. For this purpose, the present invention adopts the following technical solutions:

Detailed implementation manners

[0045] The present invention will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0046] As Figure 1-17 shown, a module sliding installation structure for offshore suspended cable photovoltaic includes a sliding cable support pillar 17, a sliding cable 13 and a sliding installation trolley 7. The sliding cable support pillar 17 is detachably connected to a pile head structure 16 on the top of a pile foundation 2. The sliding cable support pillars 17 are distributed around the photovoltaic module 4 to enclose an overall working area. The sliding cable 13 is connected between the sliding cable support pillars 17 along the direction of the load-bearing cable 3. The sliding installation trolley 7 is arranged on the sliding cable 13, and a power lifting device 5 that can be connected to the photovoltaic support 42 on the photovoltaic module 4 is arranged therein. A groove is formed at the bottom of the sliding installation trolley 7, and the opening direction of the groove corresponds to the load-bearing cable 3. An electric bolt fastener 9 that can cooperate with a bolt 103 on the photovoltaic support 42 is arranged in the groove. A cavity is arranged on the side wall of the groove, and an upper pressing block 102 that can be automatically moved out is received in the cavity. The upper pressing block 102 can also be connected and cooperated with the bolt 103, so that the photovoltaic module 4 is tightly connected to the load-bearing cable 3 through the upper pressing block 102.

[0047] As Figure 1-13As shown, specifically, the sliding installation trolley 7 is independently arranged on each sliding cable 13. Thus, the overall structure is equipped with two sliding installation trolleys 7, and a steel beam 14 is connected between adjacent sliding installation trolleys 7 to form an overall sliding structure. The two sliding installation trolleys 7 are connected by the steel beam 14 to keep their relative positions unchanged.

[0048] Among them, a receiving body is arranged at the bottom of the sliding installation trolley 7, and a groove is arranged inside the receiving body; a driving wheel 6 is arranged below the sliding installation trolley 7, and the driving wheel 6 is arranged in a staggered manner with the receiving body to avoid the driving wheel 6 affecting the installation control of the photovoltaic module 4. At the same time, two sets of driving wheels 6 are equipped below each sliding installation trolley 7, and the driving wheels 6 are connected to the sliding cable 13 so that the sliding installation trolley 7 can move stably along the cable direction on the sliding cable 13 through remote control.

[0049] Among them, a spring 8 is connected to the inner side wall of the cavity. The spring 8 is located between the inner side wall of the cavity and the upper pressing block 102, and an electric door 11 is arranged at the outlet of the cavity so that the upper pressing block 102 is received in the cavity when the electric door 11 is closed, and can be ejected from the cavity under the elastic force of the spring 8 after the electric door 11 is opened.

[0050] Among them, a telescopic motor 91 is arranged in the groove. The telescopic motor 91 is connected to the electric bolt fastener 9, and a nut 15 that can cooperate with the bolt 103 is pre-installed in the electric bolt fastener 9 so that the upper pressing block 102 is integrally fixed when connected to the photovoltaic support 42.

[0051] Specifically, the power lifting device 5 includes a cable 51 and a winch 52. The winch 52 is installed in the sliding installation trolley 7. One end of the cable 51 is connected to the winch 52, and the other end extends out of the sliding installation trolley 7 and is connected to the photovoltaic support 42, so that the object below the sliding installation trolley 7 can be freely lifted.

[0052] In this embodiment, the sliding cable support 17, the sliding cable 13, and the sliding installation trolley 7 are not fixed and can be reused, which can maximize the sharing and saving of installation costs and reduce the construction cost.

[0053] Such as Figure 9-11As shown in the figure, in this embodiment, a pressing plate type block-cable connection structure is provided to connect the photovoltaic module 4 to the load-bearing cable 3. The pressing plate type block-cable connection structure 10 includes a lower pressing block 101 pre-fixed at the end of the photovoltaic bracket 42, and a separate upper pressing block 102. Groove parts that can cooperate with the load-bearing cable 3 are respectively arranged on the mating surfaces of the upper pressing block 102 and the lower pressing block 101, so that after the upper pressing block 102 and the lower pressing block 101 are mated, they can be fixed to the load-bearing cable 3 accordingly. Bolts 103 are arranged on both sides of the lower pressing block 101 relative to its inner groove part, and connection holes for the bolts 103 to pass through are arranged through the upper pressing block 102, so that the upper pressing block 102 can pass through the bolts 103 to be attached to the lower pressing block 101 for subsequent connection.

[0054] As Figure 14-17 shown, in this embodiment, a photovoltaic module with double-span and double-row is taken as an example for the offshore photovoltaic support structure (not limited to this), and corresponding installation processing is carried out in cooperation with the module sliding installation structure.

[0055] Specifically, the pile head structure 16 includes a hanging plate 61 arranged at the top of the pile foundation 2 and a pin column. The pin column is connected to the hanging plate 61, and an upper pin column 162 is arranged on the part of the pin column extending above the hanging plate 61; the sliding cable support column 17 is sleeved on the upper pin column 162. Among them, the load-bearing cable 3 is connected to the hanging plate 61 so that the photovoltaic module 4 can be installed on the load-bearing cable 3 in this operation area.

[0056] Specifically, a support column hanging plate 171 is arranged on the outer surface of the sliding cable support column 17, and the support column hanging plate 171 is connected to the sliding cable 13. And, in this operation area, the distance between adjacent sliding cables 13 is greater than the distance between adjacent load-bearing cables 3 to facilitate the installation operation of the photovoltaic module 4.

[0057] Among them, the pin column is provided with a lower inserted pin column 163 and an upper pin column 162 according to the different positions extended inside the hanging plate 61; at the top of the pile foundation 2, the lower inserted pin column 163 of the pile head structure 16 is inserted into the pile foundation 2 and grouted for connection. The sliding cable support column 17 is sleeved outside the upper pin column 162 of the pile head structure 16 and is fixedly connected to the pile head structure 16 through bolts and nuts 18.
