Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-ice cone, in particular to an anti-ice cone unit and an anti-ice single pile foundation. BACKGROUND

[0002] In recent years, the development of offshore wind power in China is very rapid, and many wind power projects have been constructed in Tianjin, Hebei, Liaoning and Shandong provinces. In the northern sea area of China, the influence of natural disasters such as typhoon on wind turbine is small, but during the 3-month ice period in winter every year, the floating body in the sea will squeeze and impact the wind power single pile foundation, resulting in complex and sensitive dynamic response behavior, which affects the stable operation of the wind turbine. Based on this, in order to effectively improve the use efficiency and service life of the single pile foundation, it is particularly important to construct a structure type that can resist the action of sea ice.

[0003] Under normal circumstances, sea ice in front of the structure may produce extrusion, buckling, shear, bending and other damage forms. Since the bending strength of sea ice is much smaller than its compressive strength, the use of appropriate structure will make the sea ice become bending damage, which can greatly reduce the force of sea ice. For the single pile foundation, the cone structure is installed near the tide level of the pile body, and the ice and the cone can change the damage mode of the sea ice from extrusion damage to bending damage when they interact, which can greatly reduce the load of the sea ice acting on the structure.

[0004] At present, the anti-ice cone used on the single pile foundation is composed of a positive cone and an inverted cone, which has a large structure and a large weight, affecting the economy of the project and being very difficult to install.

[0005] In addition, the large size of the existing anti-ice cone will increase the wave load of the supporting structure in the season without sea ice, affecting the economy and safety of the structure.

[0006] Therefore, how to solve the problem of difficult installation caused by the large structure and large weight of the anti-ice cone is a technical problem that needs to be solved by those skilled in the art at present. SUMMARY

DETAILED DESCRIPTION

[0045] The core of the present application is to provide an anti-ice-pyramid unit to solve the problem of difficult installation caused by the large size and heavy weight of the anti-ice-pyramid structure.

[0046] Another core of the present application is to provide an anti-ice single-pile foundation with the above anti-ice-pyramid unit.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0048] As shown in Figs. Figure 1 and Figure 2 An anti-ice-pyramid unit 100 according to an embodiment of the present application is disclosed, which is arranged on the outer surface of a single-pile foundation 200, and includes a base plate 101, an upper pyramid plate 103, and a lower pyramid plate 104.

[0049] The base plate 101 is arranged on the outer surface of the single-pile foundation 200, and covers less than 1 / 2 of the circumference of the single-pile foundation 200. It can be understood that the traditional anti-ice-pyramid is divided into multiple anti-ice-pyramid units to reduce the weight and volume of a single anti-ice-pyramid unit, which can be installed in multiple times, and is easier to install.

[0050] The upper cone plate 103 is arranged on the base plate 101, the lower cone plate 104 is arranged on the base plate 101, and the upper cone plate 103 and the lower cone plate 104 form an anti-ice cone structure when the upper cone plate 103 and the lower cone plate 104 are in the first state. The upper cone plate 103 and the lower cone plate 104 can only have one positional relationship, that is, the first state; or more positional relationships can be set according to requirements. The anti-ice cone structure formed by the upper cone plate 103 and the lower cone plate 104 can have the same inclination angle as the anti-ice cone in the prior art. Of course, the included angle between the upper cone plate 103 and the lower cone plate 104, and the included angle between the upper cone plate 103 and the lower cone plate 104 and the single pile foundation 200, can be set according to the actual application scene and the sea area position.

[0051] The anti-ice cone unit 100 provided by the application is fixed on the outer surface of the single pile foundation 200 through the base plate 101, and the upper cone plate 103 and the lower cone plate 104 are installed on the base plate 101 and can at least ensure that the upper cone plate 103 and the lower cone plate 104 can form an anti-ice cone structure after installation. The anti-ice cone unit 100 provided by the application has a coverage range of the single pile foundation 200 less than 1 / 2 of the outer surface of the single pile foundation 200, that is, at least two anti-ice cone units 100 can be installed on one single pile foundation 200. The application divides the traditional anti-ice cone into multiple anti-ice cone units 100, so that the volume and weight of a single anti-ice cone unit 100 are less than 1 / 2 of the existing anti-ice cone, and therefore the anti-ice cone unit 100 is easier to install.

[0052] In order to facilitate the fixation of the upper cone plate 103 and the lower cone plate 104 on the base plate 101, in the embodiment, the upper cone plate 103 is installed on the base plate 101 through the upper cone plate support 105, and the lower cone plate 104 is installed on the base plate 101 through the lower cone plate support 106. The upper cone plate 103 can be fixed on the upper cone plate support 105 through fasteners, or can be directly welded on the upper cone plate support 105; correspondingly, the lower cone plate 104 can be fixed on the lower cone plate support 106 through fasteners, or can be directly welded on the lower cone plate support 106.

[0053] The upper cone plate support 105 and the lower cone plate support 106 can be fixed on the base plate 101 through fasteners, or can be welded on the base plate 101. When the upper cone plate support 105 and the lower cone plate support 106 are fixed on the base plate 101 through fasteners, the base plate 101 can be provided with multiple fixing positions at different positions, so that when the upper cone plate support 105 and the lower cone plate support 106 are respectively fastened to different fixing positions, the installation positions of the upper cone plate 103 and the lower cone plate 104 can be changed, and the included angle of the upper cone plate 103 and the lower cone plate 104 can be changed.

[0054] Further, the first end of the upper cone plate support 105 is hinged to the second end of the lower cone plate support 106. It is to be noted that the first end and the second end are not directional, but are used to distinguish the two ends of the upper cone plate support 105 and the lower cone plate support 106.

[0055] At least one of the second end of the upper cone plate support 105 and the first end of the lower cone plate support 106 is slidingly fitted to the base plate 101, so that the upper cone plate 103 and the lower cone plate 104 are adjusted between the first state and the second state. When the upper cone plate 103 and the lower cone plate 104 are in the second state, the upper cone plate 103 and the lower cone plate 104 are laid flat on the base plate 101.

[0056] For example, the first end of the lower cone plate support 106 is hinged to the base plate 101, and the second end of the upper cone plate support 105 is slidingly fitted to the base plate 101; or the first end of the lower cone plate support 106 is slidingly fitted to the base plate 101, and the second end of the upper cone plate support 105 is hinged to the base plate 101; or the first end of the lower cone plate support 106 is slidingly fitted to the base plate 101, and the second end of the upper cone plate support 105 is slidingly fitted to the base plate 101.

[0057] For ease of understanding, after the anti-ice cone unit 100 is installed on the single pile foundation 200, the first end of the upper cone plate support 105 and the first end of the lower cone plate support 106 are located at the lower end of the single pile foundation 200, and the second end of the upper cone plate support 105 and the second end of the lower cone plate support 106 are located at the upper end of the single pile foundation 200. The lower end of the upper cone plate support 105 is hinged to the upper end of the lower cone plate support 106, and at least one of the upper end of the upper cone plate support 105 and the lower end of the lower cone plate support 106 is slidingly fitted to the base plate 101.

[0058] When the lower end of the lower cone plate support 106 is hinged to the base plate 101, and the upper end of the upper cone plate support 105 is slidingly fitted to the base plate 101, the included angle between the upper cone plate support 105 and the lower cone plate support 106, i.e. the included angle between the upper cone plate 103 and the lower cone plate 104, can be changed by sliding the upper end of the upper cone plate support 105 up and down. As shown in FIG. 2B, when the upper end of the upper cone plate support 105 is slid downward, the lower end of the lower cone plate support 106 is hinged to the base plate 101 and cannot be moved, and the lower end of the upper cone plate support 105 is hinged to the upper end of the lower cone plate support 106, so that the included angle between the upper cone plate 103 and the lower cone plate 104 gradually decreases, and the lower end of the upper cone plate support 105 and the upper end of the lower cone plate support 106 gradually protrude outward, until the upper end of the upper cone plate support 105 is fixed after being adjusted to the appropriate position (e.g. the upper cone plate 103 and the lower cone plate 104 are in the first state). Figure 2

[0059] ​When the upper end of the upper conical plate support 105 slides upward, the lower end of the lower conical plate support 106 is hinged to the base plate 101 and cannot move. Since the lower end of the upper conical plate support 105 is hinged to the upper end of the lower conical plate support 106, the included angle between the upper conical plate 103 and the lower conical plate 104 gradually increases. The lower end of the upper conical plate support 105 and the upper end of the lower conical plate support 106 gradually retract until they are adjusted to a suitable position (such as when the upper conical plate 103 and the lower conical plate 104 are in the second state). Then, the upper end of the upper conical plate support 105 can be fixed.

[0060] When the lower end of the lower conical plate support 106 is slidably engaged with the base plate 101, and the upper end of the upper conical plate support 105 is hinged to the base plate 101, the angle between the upper conical plate support 105 and the lower conical plate support 106, i.e., the angle between the upper conical plate 103 and the lower conical plate 104, can be changed by sliding the lower end of the lower conical plate support 106 up and down. Figure 2 As shown, when the lower end of the lower conical plate bracket 106 slides upward, the upper end of the upper conical plate bracket 105 is hinged to the base plate 101 and cannot move, while the lower end of the upper conical plate bracket 105 is hinged to the upper end of the lower conical plate bracket 106, causing the included angle between the upper conical plate 103 and the lower conical plate 104 to gradually decrease, and the lower end of the upper conical plate bracket 105 and the upper end of the lower conical plate bracket 106 to gradually protrude outward until they are adjusted to a suitable position (such as when the upper conical plate 103 and the lower conical plate 104 are in the first state), the lower end of the lower conical plate bracket 106 can be fixed.

[0061] When the lower end of the lower conical plate bracket 106 slides downward, the upper end of the upper conical plate bracket 105 is hinged to the base plate 101 and cannot move, while the lower end of the upper conical plate bracket 105 is hinged to the upper end of the lower conical plate bracket 106, causing the included angle between the upper conical plate 103 and the lower conical plate 104 to gradually increase, and the lower end of the upper conical plate bracket 105 and the upper end of the lower conical plate bracket 106 to gradually retract until they are adjusted to a suitable position (such as when the upper conical plate 103 and the lower conical plate 104 are in the second state), the lower end of the lower conical plate bracket 106 can then be fixed.

[0062] When the lower end of the lower conical plate support 106 slides in engagement with the base plate 101, and the upper end of the upper conical plate support 105 also slides in engagement with the base plate 101, the angle between the upper conical plate support 105 and the lower conical plate support 106, i.e., the angle between the upper conical plate 103 and the lower conical plate 104, can be changed by sliding the lower end of the lower conical plate support 106 and / or the upper end of the upper conical plate support 105 up and down. Figure 2As shown, when the lower end of the lower cone plate support 106 slides upward and / or the upper end of the upper cone plate support 105 slides downward, the included angle between the upper cone plate 103 and the lower cone plate 104 gradually decreases due to the hinged connection between the lower end of the upper cone plate support 105 and the upper end of the lower cone plate support 106, and the lower end of the upper cone plate support 105 and the upper end of the lower cone plate support 106 gradually protrude outward, until the adjustment is made to the appropriate position (e.g., the upper cone plate 103 and the lower cone plate 104 are in the first state), and the lower end of the lower cone plate support 106 can be fixed.

[0063] When the lower end of the lower cone plate support 106 slides downward and / or the upper end of the upper cone plate support 105 slides upward, the included angle between the upper cone plate 103 and the lower cone plate 104 gradually increases due to the hinged connection between the lower end of the upper cone plate support 105 and the upper end of the lower cone plate support 106, and the lower end of the upper cone plate support 105 and the upper end of the lower cone plate support 106 gradually retract, until the adjustment is made to the appropriate position (e.g., the upper cone plate 103 and the lower cone plate 104 are in the second state), and the lower end of the lower cone plate support 106 can be fixed.

[0064] When the lower end of the lower cone plate support 106 and the upper end of the upper cone plate support 105 slide downward or upward simultaneously, the position of the anti-ice cone unit 100 on the single pile foundation 200 can be adjusted to adapt to different water levels.

[0065] In summary, in the above technical solution, the upper cone plate 103 and the lower cone plate 104 are installed by the upper cone plate support 105 and the lower cone plate support 106, and the end of at least one of the upper cone plate support 105 and the lower cone plate support 106 is slidable to adjust the angle between the upper cone plate 103 and the lower cone plate 104, so that the upper cone plate 103 and the lower cone plate 104 are adjusted between the first state and the second state. When the upper cone plate 103 and the lower cone plate 104 are in the first state, the upper cone plate 103 and the lower cone plate 104 form an anti-ice cone structure, and when the upper cone plate 103 and the lower cone plate 104 are in the second state, the upper cone plate 103 and the lower cone plate 104 are laid flat on the base plate 101. In the ice period of winter, the upper cone plate 103 and the lower cone plate 104 are adjusted to the first state to form an anti-ice cone structure to reduce ice load and protect the single pile foundation; in the non-ice period, the upper cone plate 103 and the lower cone plate 104 are adjusted to the second state, and the upper cone plate 103 and the lower cone plate 104 are laid flat on the surface of the single pile foundation 200, the anti-ice cone structure disappears, and the structure diameter is reduced to reduce the wave load.

[0066] As shown in FIG. 1, the anti-ice cone unit 100 is installed on the single pile foundation 200, and the base plate 101 is fixed on the single pile foundation 200. The anti-ice cone unit 100 includes an upper cone plate 103, a lower cone plate 104, an upper cone plate support 105, and a lower cone plate support 106. The upper cone plate 103 and the lower cone plate 104 are arranged in a cone shape, and the upper cone plate 103 and the lower cone plate 104 are arranged in a cone shape. The upper end of the upper cone plate support 105 is connected to the lower end of the upper cone plate 103, and the lower end of the lower cone plate support 106 is connected to the upper end of the lower cone plate 104. The upper end of the upper cone plate support 105 and the lower end of the lower cone plate support 106 are hinged to each other. Figure 3 and Figure 4As shown, in a specific embodiment of the present application, a sliding groove 1011 is formed on the side of the base plate 101 opposite to the single-pile foundation 200, the second end of the upper conical plate support 105 is slidably connected to the sliding groove 1011 through a sliding plate 102, and the first end of the lower conical plate support 106 is hingedly connected to the base plate 101. In this embodiment, the sliding groove 1011 is formed on the base plate 101, and the sliding plate 102 is inserted into the sliding groove 1011 and slides along the sliding groove 1011. The sliding plate 102 and the sliding groove 1011 are slidably connected, so as to limit the sliding direction of the second end of the upper conical plate support 105.

[0067] In a specific embodiment of the present application, the upper end of the sliding groove 1011 penetrates the upper end of the base plate 101, the two sides of the sliding groove 1011 are provided with limiting grooves 1012, the sliding plate 102 is inserted into the sliding groove 1011 and provided with limiting plates extending into the limiting grooves 1012 on the two sides, so as to prevent the sliding plate 102 from being pulled out of the sliding groove 1011. When the sliding plate 102 is installed, it can be inserted from the upper end of the sliding groove 1011, so that the limiting plates on the two sides of the sliding plate 102 are inserted into the limiting grooves 1012 on the two sides, and then the sliding plate 102 is slid downward to complete the installation.

[0068] In a specific embodiment of the present application, the lower end of the sliding groove 1011 is blocked to form a first state limiting part 1013, that is, the upper end of the sliding groove 1011 penetrates the upper end of the base plate 101 to form an opening end, and the lower end is blocked to form the first state limiting part 1013. When the sliding plate 102 slides to abut against the first state limiting part 1013, it will be blocked by the first state limiting part 1013, and at this time, the upper conical plate 103 and the lower conical plate 104 are in the first state. In this embodiment, the first state limiting part 1013 is arranged on the sliding groove 1011, so as to conveniently position the first state of the upper conical plate 103 and the lower conical plate 104, which only needs to control the sliding plate 102 to slide downward to the limit position along the sliding groove 1011.

[0069] In order to conveniently fix the sliding plate 102, in this embodiment, the anti-icing cone unit further comprises a locking member for fastening the sliding plate 102 to different positions of the sliding groove 1011. The locking member can at least fix the sliding plate 102 to a position, so that the upper conical plate 103 and the lower conical plate 104 are in the first state and the second state.

[0070] In an embodiment of the present application, the first hinge support 108 is arranged on the base plate 101, the second hinge support 107 is arranged on the sliding plate 102, and the second end of the upper conical plate support 105 is hinged to the second hinge support 107; the first end of the lower conical plate support 106 is hinged to the first hinge support 108.
