In the installation process of the protection cover 100 according to the embodiment of the present utility model, since the diameter of the steel pipe pile 200 for offshore wind power is large, the number of the first cover body 1 and the second cover body 2 is generally set to be plural, for example, two, four or eight. In the installation process, a plurality of first and second covers 1 and 2 are arranged around the steel pipe pile 200, the inner peripheral surface of each first cover 1 and the inner peripheral surface of the second cover 2 are attached to the outer peripheral surface of the steel pipe pile 200, and the first flange 102 and the second flange 103 on the first cover 1 are connected with the first flange 102 and the second flange 103 of the adjacent first cover 1 by bolts 300.

When the first cover body 1 and the second cover body 2 are connected in an inserting mode through the plug 201 and the slot 101 in the axial direction of the steel pipe pile 200, connection of the first cover body 1 and the second cover body 2 in the axial direction of the steel pipe pile 200 is achieved, the fact that flange structures are arranged in the axial direction of the first cover body 1 and the second cover body 2 in the axial direction of the steel pipe pile 200 are connected through bolts is avoided, quick positioning of the first cover body 1 and the second cover body 2 in the axial direction of the steel pipe pile 200 can be achieved, installation is simple, and installation efficiency of the protection cover 100 is improved. In addition, the heavy high corrosion resistant bolt connection is omitted, so that the overall weight of the protective cover 100 is reduced, and the installation cost is saved.

Therefore, the protective cover 100 of the embodiment of the present utility model has advantages of simple installation and low installation cost.

In some embodiments, for example, as shown in fig. 4 and 6, the protection cover 100 of the embodiment of the present utility model includes a sealing member 3, where the sealing member 3 is disposed between the plug 201 and the socket 101 to seal the plug 201 and the socket 101, and prevent seawater from flowing between the protection cover 100 and the steel pipe pile 200 from an assembly gap between the plug 201 and the socket 101, so as to corrode the steel pipe pile 200, which is advantageous for improving the protection reliability of the protection cover 100 of the embodiment of the present utility model.

Optionally, the sealing member 3 is made of foamed plastic or rubber, so that the material is easy to obtain, the cost is low, and further cost saving is facilitated.

In some embodiments, the seal 3 is disposed between the outer circumferential surface of the plug 201 and the groove inner wall of the socket 101 in the radial direction of the protective cover 100.

For example, as shown in fig. 5 and 6, only the seal member 3 is provided between the outer peripheral surface of the plug 201 and the groove inner wall of the slot 101, and the seal between the first cover 1 and the second cover 2 is achieved in the radial direction for the protection cover 100, so that the sealing effect is achieved, and the material consumption of the seal member 3 is reduced, thereby further contributing to cost saving.

In some embodiments, the protrusion 104 is disposed in the socket 101, the protrusion 104 is protruding along the axial direction of the protection cover 100, the protrusion 104 and the inner wall of the socket 101 clamp the seal member 3 in the radial direction of the protection cover 100, and the plug 201 abuts against the protrusion 104 in the axial direction of the protection cover 100.

For example, as shown in fig. 5 and 6, when the sealing member 3 is installed, the sealing member 3 may be preset between the boss 104 and the inner wall of the slot 101, and then the connection between the first cover 1 and the second cover 2 is performed, so that the installation of the protection cover 100 is convenient, which is advantageous for improving the installation efficiency.

In other embodiments, the seal 3 includes a first segment 301 and a second segment 302 connected, the first segment 301 and the second segment 302 being disposed in an L-shape. The first segment 301 extends in the radial direction of the protective cover 100 and is provided between the first cover 1 and the second cover 2 in the axial direction of the protective cover 100, and the second segment 302 extends in the axial direction of the protective cover 100 and is provided between the first cover 1 and the second cover 2 in the radial direction of the protective cover 100.

As shown in fig. 3 and 4, the first segment 301 can seal the assembly gap between the first cover 1 and the second cover 2 in the axial direction of the steel pipe pile 200, and the second segment can seal the assembly gap between the first cover 1 and the second cover 2 in the radial direction of the steel pipe pile 200. By providing the seal 3 with the L-shaped first and second segments 301 and 302, double sealing of the fitting gap between the first and second covers 1 and 2 can thereby be achieved, which is further advantageous in improving the sealing reliability of the seal 3.

In addition, because the first cover 1 and the second cover 2 have larger weight, when the plug 201 of the first cover 1 is inserted into the slot 101 of the second cover 2, the first section 301 of the sealing member 3 can also play a role in buffering the space between the first cover 1 and the second cover 2, so that the first cover 1 and the second cover 2 are prevented from being deformed by stress due to rigid contact, and the installation reliability of the protection cover 100 is improved.

Optionally, the seal 3 is adhesively connected to at least one of the first cover 1 and the second cover 2. That is, the sealing element 3 may be disposed on the first cover 1 for bonding, or the sealing element 3 is bonded only with the second cover 2, or the sealing element 3 is bonded with both the first cover 1 and the second cover 2 respectively, so as to prevent the sealing element 3 from falling off during use, which is beneficial to improving the connection reliability of the sealing element 3.

In some embodiments, the first cover 1 comprises a first rigid layer 105 and a first flexible layer 106, the first flexible layer 106 being provided on the inside of the first rigid layer 105.

When a ship or other object hits the first cover 1 on the steel pipe pile 200, the first rigid layer 105 plays a role of rigid protection against damage to the steel pipe pile 200 due to rigid collision. The first flexible layer 106 serves as a buffer to prevent the steel pipe pile 200 from breaking and failing due to excessive impact force of ships and other objects.

In some embodiments, the second enclosure 2 includes a second rigid layer 204 and a second flexible layer 205, the second flexible layer 205 being disposed inside the second rigid layer 204.

When a ship or other object impacts the second casing 2 on the steel pipe pile 200, the second rigid layer 204 plays a role of rigid protection against damage to the steel pipe pile 200 due to rigid impact. The second flexible layer 205 serves as a buffer to prevent the steel pipe pile 200 from breaking and failing due to excessive impact force of ships and other objects.

Optionally, the first rigid layer 105 and the second rigid layer 204 are made of a fiber reinforced composite.

For example, the first rigid layer 105 and the second rigid layer 204 are each fiber reinforced composite plastic composed of carbon fiber, glass fiber, boron fiber, plant fiber, basalt fiber, or the like and an unsaturated polyester, epoxy, or phenolic matrix.

Alternatively, the first flexible layer 106 and the second flexible layer 205 are made of foamed plastic or rubber.

For example, the first flexible layer 106 and the second flexible layer 205 are made of foamed plastic, rubber, or the like.
