Problems solved by technology

For installation, the installation structures in the prior art are designed on the shore. Due to the ebb and flow of the tide, the structure fixed on the shore is basically unusable in practice; The situation is, one is the fixed type, the whole platform is fixed by pile driving, this method is expensive, and there is not much difference between the fixed platform and fixed on the shore, and the ability to use the tide is also very poor; the other is the floating type, fixed by anchors, The floating type can follow the ups and downs of the tide and make good use of the tidal current energy. However, to complete the floating, the existing technology uses an airbag structure to adjust the buoyancy, and the airbag is difficult to use for a long time in the sea environment; warehouse, while the floating warehouse has a huge structure and high cost, and can only adapt to a certain structure of the power generation device, which has great limitations
For floating tidal current power generation equipment, none of the existing installation structures can adapt to practical use

Embodiment 1

[0015] A manufacturing method for the installation structure of floating tidal current power generation equipment. According to the total weight of the power generation equipment required to be placed, a floating installation structure frame is constructed through buoyancy calculation. The installation structure frame is composed of several buoyancy tubes connected. The hollow tube of the corresponding size corresponding to the requirements is expanded and filled with light corrosion-resistant foam material, and the two ends of the hollow tube are sealed to form a buoyancy tube.

[0016] The fabrication of the floating installation structure frame is carried out in a dry water dock connected to sea water. After the fabrication is completed, the gate is opened to release water into the dry water dock. After the floating installation structure frame floats, it is towed to the designated place for anchoring. Due to the large size of the floating installation structure frame, many ...

Embodiment 2

[0019] As a specific structural design of Example 1, the hollow tube is a steel tube. The steel pipe is chosen as the material of the hollow pipe, because it has a certain strength, so that the frame has a certain ability to resist the waves in the sea.

[0020] Preferably, ribs and steel mesh are welded on the outer surface of the steel pipe, and the frame is sprayed with marine concrete to form a platform frame. The laid ribs and steel mesh are sprayed with marine concrete to protect the outer surface of the steel pipe and make the platform frame meet the installation requirements. The thickness of the sprayed grout is determined by the specific buoyancy design; the design of the ribs and steel mesh is also Another advantage is that if the cement is directly poured, it will be insufficiently emphasized due to the thin thickness, resulting in bursting; if the thickness is thick, the strength is enough, but the platform cannot float in sea water.

[0021] As a preference, pol...

Abstract

The invention discloses a manufacturing method of a floating type tidal current power generation equipment installation structure. A floating installation structure frame is constructed through buoyancy calculation according to the total weight of power generation equipment needing to be placed, the installation structure frame is formed by connecting a plurality of buoyancy pipes, the buoyancy pipes are hollow pipes with the corresponding sizes corresponding to the buoyancy requirements, the hollow pipes are filled with light corrosion-resistant foam materials in an expanded mode, and the two ends of the hollow pipe are sealed to form the buoyancy pipe. The structure can rise and fall along with free tide water, and the effect that the power generation equipment enters water to take power is guaranteed; the structure is simple, buoyancy can be guaranteed, and the buoyancy effect of the whole frame is still not affected even if the frame generates leakage points due to seawater corrosion; and reinforced cement layer not only can prolong the corrosion time of seawater to a frame main body and increase certain stability, but also can effectively form connection and facilitate the installation and fixation of the power generation equipment.

Description

technical field [0001] The invention relates to the technical field of water flow power generation equipment, in particular to a method for manufacturing an installation structure of floating tidal current power generation equipment. Background technique [0002] At present, tidal current power generation is recognized as a promising clean energy source. However, due to the harsh environment at sea and the strong corrosion performance of seawater, the popularization and application of seawater tidal current power generation has been plagued. One of the core issues is how to install the problem. For installation, the installation structures in the prior art are designed on the shore. Due to the ebb and flow of the tide, the structure fixed on the shore is basically unusable in practice; The situation is, one is the fixed type, the whole platform is fixed by pile driving, this method is expensive, and there is not much difference between the fixed platform and fixed on the sh...
