Description

Technical Field

[0001] This utility model relates to the field of wind power foundation construction technology, and in particular to a conventional ship pipe pile insertion device for high surge conditions. Background Technology

[0002] The wind turbine foundation is the fixed end of the wind turbine generator set. Together with the tower, it erects the turbine at a height of 60-100 meters. It is a crucial component ensuring the normal power generation of the wind turbine. Wind turbine foundations are typically reinforced concrete structures, designed in different forms according to local geological conditions. They are mainly constructed based on the tower load and the climate environment where the turbine is located, in accordance with high-rise building construction standards. In domestic completed and under-construction jacket wind turbine foundation projects, the pile foundation types generally include driven piles and embedded rock-socketed piles. For wind farms with relatively thin overburden, jacket foundations often require rock embedding to increase the foundation's pull-out resistance. The construction process for embedded rock-socketed steel pipe piles involves: installing a rock-socketing platform on the seabed, driving a steel casing to the predetermined rock layer, drilling a borehole to the design elevation, and inserting the embedded steel pipe piles. After the steel casing is stabilized, a drilling rig is used to drill the hole to the design pile bottom elevation. The steel pipe pile is then inserted into the hole and fixed. However, due to extreme weather conditions and sea surges at sea, existing embedded rock-socketed pile construction operations often cannot smoothly utilize ship-mounted cranes to lift the steel pipe piles into the borehole. Furthermore, extreme weather conditions such as heavy fog and strong winds further affect the efficiency of lifting the steel pipe piles, significantly reducing the construction progress and causing the lifting operation to fail to achieve the expected goals. Utility Model Content

[0003] To address the shortcomings of existing technologies, a conventional shipboard pipe pile installation device is provided for high wave surge conditions, which solves the problem that existing technologies cannot hoist and install steel pipe piles into holes under wave surges of around two meters and extreme weather conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a conventional ship pipe pile entry device for high surge conditions. The pipe pile entry device is installed on a rock-embedded borehole. The rock-embedded borehole is opened on and passes through the offshore ship's working platform. The offshore ship's working platform is also equipped with a crane for hoisting steel piles. The pipe pile entry device includes several triangular guide plates arranged symmetrically around the entrance of the rock-embedded borehole.

[0005] Preferably, the pipe pile entry device further includes micro-motion sensing devices disposed on the sides of each triangular guide plate.

[0006] Preferably, the triangular guide plate is fixedly connected to the rock-embedded hole by welding.

[0007] Preferably, the rock-embedded hole has several vertical grooves at the entrance position, and several bolt lugs are welded on the inner and outer sides of the rock-embedded hole at the groove position. The triangular guide plate has through holes for bolt penetration and fixing. After the triangular guide plate is embedded in the groove, it is detachably connected to the rock-embedded hole by bolts.

[0008] Preferably, there are at least six sets of triangular guide plates, symmetrically arranged around the rock-embedded borehole.

[0009] The beneficial effects of this utility model are:

[0010] This invention can ensure that the installation of steel piles in the borehole is not affected by high waves at sea, especially when the waves reach about two meters, or in foggy weather; the guide plate enables the hoisting personnel to smoothly install steel piles in the borehole under extreme weather conditions.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-2As shown, a conventional shipboard pipe pile entry device for high surge conditions is disclosed. The device is installed on a rock-embedded borehole 1, which is located on and extends through a marine working platform 2. A crane 3 is also installed on the marine working platform 2 for hoisting steel pipe piles 4. The device includes several triangular guide plates 5 arranged symmetrically around the entrance of the rock-embedded borehole 1. In this embodiment, several triangular guide plates 5 are vertically arranged at the entrance of the rock-embedded borehole 1. The guide plates 5 are preferably made of stainless steel to overcome the humid marine environment. The stainless steel material also produces a louder collision sound, which is suitable for alerting the hoisting personnel to the collision of the steel pipe pile 4. The triangular guide plate 5 is preferably a right-angled triangle structure, with the pointed end facing upwards and the hypotenuse facing the rock-embedded borehole 1 during installation. This embodiment can perfectly cope with the swaying caused by high surges, especially when the surge is about two meters high, and can realize the hoisting and hole installation operation of the steel pipe pile 4 in a high surge environment.

[0017] Preferably, the pipe pile entry device further includes a micro-motion sensor 6 disposed on the side of each triangular guide plate 5. In this embodiment, when the hoisted steel column pile 4 comes into contact with the triangular guide plate 5, a collision occurs, generating vibration. The micro-motion sensor 6 sends a signal to the crane operator, and the hoisting operator adjusts the hoisting direction according to the feedback of the electrical signal to complete the hoisting.

[0018] Preferably, the triangular guide piece 5 is fixedly connected to the rock-embedded hole 1 by welding. This embodiment is the first embodiment of this application. Fixing the triangular guide piece 5 by welding can ensure that the structure does not tilt when it collides with the steel column pile 4.

[0019] Preferably, the rock-embedded borehole 1 has several vertical grooves 7 at its inlet. Several bolt lugs 8 are welded to the inner and outer sides of the grooves on both sides of the rock-embedded borehole 1. The triangular guide plate 5 has through holes for bolt penetration and fixing. After being embedded in the grooves 7, the triangular guide plate 5 is detachably connected to the rock-embedded borehole 1 by bolts. Figure 3 As shown, this embodiment is the second embodiment of this application. In use, several grooves 7 are symmetrically opened at the entrance of the rock-embedded hole 1. During installation, bolt holes 8 are welded on the inner and outer sides of the rock-embedded hole 1. During installation, the guide plate 5 is inserted into the groove 7 and then fixed by bolts through the guide plate 5 to realize the detachable connection of the guide plate 5. In this embodiment, it is convenient to disassemble and replace the triangular guide plate 5 during use. At the same time, the number of triangular guide plates 5 can be adjusted as needed, further improving the success rate of hoisting.

[0020] Preferably, there are at least six sets of triangular guide plates 5, symmetrically arranged around the rock-embedded hole 1. In use, since this application is typically used for rock-embedded holes with a diameter of 2M, it is preferable to install six sets of triangular guide plates 5 around the hole opening.

[0021] The working principle of this application is as follows: Firstly, when lifting steel piles at sea or when lifting them into boreholes, the working platform of the offshore vessel is often affected by swells or extreme weather, and the lifting machinery such as cranes is unstable, resulting in a low success rate of lifting. Therefore, when it is necessary to implant rock-socketed steel pipe piles, several triangular guide plates are first installed at the top of the entrance of the rock borehole. Then, the steel pipe column is lifted by a crane to the top of the borehole. The lifting workers lower the height of the steel pipe column. When the steel pipe column comes into contact with the guide plates at the borehole, a collision occurs, which reminds the workers to adjust the direction. The steel pipe column is then successfully lifted into the borehole by relying on the guide plates.

[0022] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
