Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions.

[0042] It should be noted that the terms used here are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present utility model. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "include" and / or "comprise" are used in this specification, they specify the presence of features, steps, operations, devices, components and / or combinations thereof.

[0043] With the continuous development of the global economy, the demand for energy is also increasing continuously. As a clean and renewable energy form, offshore wind power can meet the growing electricity demand, reduce the dependence on fossil fuels, and thus reduce greenhouse gas emissions. In an offshore wind power project, the wind turbine tower, as the support structure of the wind turbine generator set, ensures the stability and safety of the entire unit. And the bottom section of the tower, as a key tower section in the wind turbine tower, is equipped with many electrical devices and electronic components. After being eroded by substances such as rainwater and dust, the electronic devices inside the bottom tower will be damaged, resulting in certain economic losses.

[0044] Therefore, the existing protection measures usually cover a rain shield on the top of the bottom tower section, and tie the rain shield to the bottom tower section through steel wires, and the tying is rather cumbersome. Moreover, with the development of offshore wind power, the diameters of the bottom tower sections vary, while the existing rain shields are of a single fixed size. When dealing with bottom tower sections of various models, rain shields of different sizes need to be replaced, increasing the labor cost.

[0045] It can be seen from this that the existing protection measures have the problems that the size of the rain shield is single and cannot cope with bottom tower sections of various models, and the installation process is cumbersome.

[0046] Based on the above technical problems, the embodiment of the present application provides a protection device for the bottom tower section. The protection device includes a protection cover and a buffer assembly. The protection cover includes a plurality of fixing components, and the plurality of fixing components are arranged on the inner wall of the protection cover and are used for fixedly installing the bottom tower section inside the protection cover. In addition, the lengths of the plurality of fixing components are determined by the diameter of the bottom tower section to match bottom tower sections of various diameters, solving the problem in the prior art that the rain shield cannot cope with bottom tower sections of various models. In addition, the buffer assembly is arranged at the lower end of the protection cover, and the buffer assembly wraps part of the bottom tower section to buffer the acting force generated when the protection device is installed on the bottom tower section.

[0047] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0048] As Figure 1As shown in the figure, an embodiment of the present application provides a protection device for a bottom tower barrel, including: a protection cover 10 and a buffer assembly 20. The protection cover 10 includes: a plurality of fixing components 30; the plurality of fixing components 30 are arranged on the inner wall of the protection cover 10 for fixedly installing the bottom tower barrel in the protection cover 10, and the length of the plurality of fixing components 30 is determined by the diameter of the bottom tower barrel; the buffer assembly 20 is arranged at the lower end of the protection cover 10, and the buffer assembly 20 wraps part of the bottom tower barrel to buffer the acting force generated when the bottom tower barrel is installed into the protection cover 10.

[0049] Among them, the shape of the protection cover 10 matches that of the bottom tower barrel. In the embodiment of the present application, the protection cover 10 is a hollow cylinder, and the protection cover 10 can be made of stainless steel material. Optionally, a layer of rainproof tarpaulin can be wrapped on the outer wall of the protection cover 10 to reduce the erosion of rain and snow on the protection device and improve the service life of the protection device.

[0050] Optionally, a clamping groove is provided at the lower end of the protection cover 10, and the buffer assembly 20 is fixed to the lower end of the protection cover 10 through the above clamping groove. Among them, the buffer assembly 20 is made of an elastic material, and the buffer assembly 20 abuts against the outer wall of the bottom tower barrel to buffer the acting force generated when the protection device is installed on the bottom tower barrel of the cover.

[0051] Optionally, as Figure 1 shown, a plurality of fixing components 30 are arranged on the inner wall of the protection cover 10. The fixing component 30 includes a connection hole penetrating through the fixing component 30. Exemplarily, the connection hole of the fixing component 30 is an oblong hole, and the present application does not limit this. In addition, the fixing components 30 are fixed on the inner wall of the protection cover 10 at uniform intervals, and the position of the connection hole of the fixing component 30 corresponds to the flange of the bottom tower barrel, so as to facilitate connection with the bottom tower barrel flange through bolts, so that the protection device is fixedly connected to the bottom tower barrel.

[0052] Optionally, a plurality of lifting lugs are provided on the upper part of the protection cover 10. The plurality of lifting lugs can be welded to the protection cover 10 or can be detachably fixed to the protection cover 10 in a threaded connection manner, so as to facilitate connection with a lifting device, and then the protection device can be transported to a predetermined position for installation through the lifting device. Among them, the shape of the lifting lug can be rectangular, circular, etc. The present application does not limit the shape of the lifting lug, and the shape of the lifting lug can be determined according to different lifting requirements.

[0053] It can be understood that, as Figure 2As shown, at least one manhole 40 is provided on the protective cover 10 for the staff to enter and exit the equipment, so as to facilitate the installation, maintenance and safety inspection of the electronic equipment or devices inside the tower barrel. Among them, a cover plate is provided on the manhole 40; a hinge and a handle are provided on the cover plate. The cover plate is hinged to the protective cover through the hinge. The handle can be made of steel bar material and is fixed to the cover plate by welding. In addition, a protective sleeve is provided on the handle. The protective sleeve is made of rubber material, which increases the friction force during the process of the staff opening the cover plate through the handle, making it more conducive to opening the cover plate.

[0054] A protective device for the bottom tower barrel provided by an embodiment of the present application includes a protective cover and a buffer assembly. The above-mentioned protective cover includes a plurality of fixing components, and the plurality of fixing components are arranged on the inner wall of the protective cover for fixing and installing the bottom tower barrel inside the protective cover. In addition, the lengths of the plurality of fixing components are determined by the diameter of the bottom tower barrel to match bottom tower barrels of various diameters, solving the problem in the prior art that the rain cover cannot cope with bottom tower barrels of various models. In addition, the above-mentioned buffer assembly is arranged at the lower end of the protective cover, and the buffer assembly wraps part of the bottom tower barrel to buffer the acting force generated when the protective device is installed on the bottom tower barrel. This protective device can not only match bottom tower barrels of various diameters, but also is flange-connected to the bottom tower barrel through a plurality of fixing components. During the installation process, only the fixing components need to be correspondingly connected to the bottom tower barrel flange through bolts, and the installation process is simpler.

[0055] Based on the above Figure 1 embodiment, a possible connection method between the plurality of fixing components 30 and the inner wall of the protective cover 10 is described in detail. This connection method includes: the plurality of fixing components 30 are welded to the inner wall of the protective cover 10.

[0056] Optionally, the fixing component 30 includes a telescopic member, a fixed sleeve, and a fixing bolt. A positioning hole is provided on the fixed sleeve to facilitate adjusting the length of the fixing component 30 according to the diameter of the bottom tower barrel. The first end of the above-mentioned telescopic member is sleeved inside the fixed sleeve and is fixedly connected through the above-mentioned positioning hole and the fixing bolt. In addition, the other end of the above-mentioned telescopic member is welded to the inner wall of the protective cover 10.

[0057] It can be understood that a rubber pad can also be provided on the lower surface of each fixing component 30 to reduce the friction force between the fixing component 30 and the tower barrel flange, and avoid wear or damage to the fixing component 30 and the tower barrel flange due to excessive tightening.

[0058] It should be noted that different scales are marked on the telescopic member, such as scales applicable to tower barrels with diameters of 7 meters, 8 meters, 9 meters, and 10 meters, so as to adjust the diameter of the hollow area of the fixing device according to the scale, and then the corresponding bottom tower barrel can be docked to achieve the effect of being adaptable to bottom tower barrels of various diameters.

[0059] Exemplarily, the size of the telescopic member is smaller than that of the fixed sleeve. The telescopic member is sleeved inside the fixed sleeve and can move inside the fixed sleeve. After adjusting the telescopic member to the corresponding position according to the diameter of the bottom tower barrel and the positioning holes on the telescopic member, the fixing bolts on the fixed sleeve are passed through the corresponding positioning holes to firmly connect the telescopic member and the fixed sleeve together.

[0060] Optionally, in the case of long-term use and only needing to adapt to one type of bottom tower barrel, the connection mode between one end of the telescopic member and the inner wall of the protective cover 10 can be welding. In the case of needing to correspond to multiple types of bottom tower barrels, one end of the telescopic member can be movably connected to the inner wall of the protective cover 10, so as to replace the telescopic member adapted to the bottom tower barrel in the case where the size of the telescopic member cannot meet the installation requirements of the bottom tower barrel, avoiding the problems of increasing workload and wasting resources caused by replacing the protective device in this case. Among them, the movable connection mode includes but is not limited to double-headed bolt connection and bolt connection.

[0061] Exemplarily, a possible protective device for the bottom tower barrel is given here. The protective device is divided into two layers. The first layer, that is, the upper layer, is the protective cover, and the second layer, that is, the lower layer, is the buffer component. The buffer component is made of rubber material and abuts against a part of the outer wall of the bottom tower barrel to buffer the collision force between the protective device and the bottom tower barrel when the protective device is installed above the bottom tower barrel. Among them, the protective cover is made of cylindrical rigid material and is a hollow cylinder without a bottom surface. A plurality of fixing components are arranged on the inner wall of the protective cover, and the fixing components are in the shape of a cuboid. In addition, the fixing component can include two parts: the first part is the telescopic member, and the second part is the fixed sleeve. Among them, positioning holes are provided on the fixed sleeve, and the positioning holes penetrate through one end of the fixed sleeve close to the inside of the bottom tower barrel. One end of the telescopic member is connected to the inner wall of the protective device, and the other end is sleeved with the fixed sleeve through the fixing bolt and the positioning hole. In addition, the above-mentioned fixing component also includes an oval connecting hole, which is used to be connected to the flange of the bottom tower barrel through bolts to fixedly arrange the protective device above the bottom tower barrel and prevent the protective device from falling or shifting due to external force.

[0062] The embodiment of the present application provides a protective device for a bottom tower tube, the protective device includes a protective cover and a buffer assembly, and a plurality of fixed components are arranged on the inner wall of the protective cover. Among them, the fixed components include: a telescopic member and a fixed sleeve, a positioning hole is arranged on the fixed sleeve, and different scales are marked on the telescopic member. One end of the telescopic member is connected to the inner wall of the protective cover, and the other end is extended and sleeved with the fixed sleeve, and can be telescopically movable in the fixed sleeve to determine the length of the telescopic member according to the diameter of the bottom tower tube, and the telescopic member and the fixed sleeve are firmly connected together through fixing bolts and positioning holes. While preventing rain, snow or dust from entering the interior of the tower tube, the protective device adjusts the length of the telescopic member according to the diameter of the bottom tower tube, so that the protective device can adapt to bottom tower tubes of various diameters.

[0063] The embodiments of the present application are based on the above Figure 1 Based on the embodiment, another possible connection method of the multiple fixing components 30 and the inner wall of the protective cover 10 is described in detail, and the connection method includes: a plurality of connecting components are arranged on the inner wall of the protective cover 10, and the multiple fixing components 30 are connected to the protective cover 10 through the multiple connecting components.

[0064] Optionally, the connection assembly includes a slider, a fixing sleeve, and a blocking member, wherein the fixing sleeve is provided with a plurality of positioning holes, the positioning holes are arranged through the fixing sleeve, and the positioning holes and the blocking member cooperate with each other to block the slider at a fixed position inside the fixing sleeve. Different positioning holes correspond to different bottom tower diameters, so that the length of the connection assembly can be adjusted according to the positioning holes, thereby achieving the effect of being adaptable to bottom towers of various diameters.

[0065] It can be understood that one end of the fixing sleeve is welded to the inner wall of the protective cover 10, and the other end is connected to the fixing component. After the slider is slid to the corresponding position according to the diameter of the bottom tower, the blocking member is passed through the corresponding positioning hole to fix the position to prevent the slider from moving in the fixing sleeve. In this way, the protective device achieves the effect of adapting to various models of bottom towers.

[0066] Optionally, the fixing component can also be connected to the inner wall of the protective cover 10 in a detachable manner. For example, a first connecting hole is provided on the inner wall of the protective cover 10, and the inner diameter of the first connecting hole is smaller than the inner diameter of the fixing component 30. During the installation process, the fixing component 30 only needs to be pressed into the first connecting hole to form a certain interference, so that the two are closely matched and a certain pre-tightening force is generated, and the detachable connection between the fixing component 30 and the protective cover 10 can be achieved.

[0067] It should be noted that the telescopic member of the fixed part can be welded to the inner wall of the protective cover 10, and the other end of the telescopic member can also be fixed to the inner wall of the protective cover 10 through the above-mentioned connection assembly. In this method, the other end of the telescopic member and the connection assembly are fixed together by means of threaded connection. This method is beneficial in cases where the protective device fails to meet the installation requirements of the bottom tower barrel, or when the fixed part of the protective device is damaged. The fixed part can be disassembled from the connection assembly to replace a fixed part that is adapted to the bottom tower barrel or a new one, avoiding the need to replace the entire protective device due to damage to the fixed part or the inability of the protective device to fit the model of the bottom tower barrel, resulting in waste of resources.

[0068] Optionally, as Figure 3 shown, on the basis of the above Figure 1-2 embodiment, a tripod provided on the protective device is given here. The tripod includes a top plate 50, a plurality of support assemblies 60, and at least two mounting parts 70; the top plate 50 is in the shape of a cuboid, and the plurality of support assemblies 60 are welded below the top plate 50 to support the top plate 50 to be inclined at a fixed angle; at least two mounting holes are further provided on the protective cover 10, and the at least two mounting parts 70 fix the tripod above the protective cover 10 through the at least two mounting holes.

[0069] Among them, the top plate 50 can be a stainless steel plate in the shape of a cuboid, and a plurality of support assemblies 60 are symmetrically welded below the top plate 50 for supporting the top plate 50 to a fixed inclination angle to prevent water or snow from accumulating on the top of the above-mentioned protective device. In addition, the mounting parts 70 on the bottom surface of the tripod are used to connect with the mounting holes on the protective cover 10 so that the tripod is fixedly connected to the top of the protective cover 10.

[0070] It should be noted that the support assembly can be a reinforcing bar or a steel pipe, and the embodiments of the present application do not limit this.

[0071] An embodiment of the present application provides a protection device for the bottom tower barrel. The protection device includes a protection cover and a buffer assembly. A plurality of connection components are provided on the inner wall of the protection cover. The plurality of connection components are used for movably connecting with a plurality of fixing components, and the connection components are of a telescopic structure, so as to adjust the length of the connection components according to the diameter of the bottom tower barrel, and further adjust the length of the fixing components, so that the fixing components correspond to the flange of the bottom tower barrel, achieving the effect of matching bottom tower barrels with different diameters. And in the case where the protection device fails to meet the installation requirements of the bottom tower barrel or is damaged, the fixing components can also be detached from the connection components to replace the fixing components adapted to the bottom tower barrel or new ones, avoiding the need to replace the entire protection device due to damage to the fixing components or the inability of the protection device to adapt to the model of the bottom tower barrel, resulting in waste of resources. In addition, a tripod is provided on the protection device, which solves the problem of water accumulation or snow accumulation on the top of the protection device.
