[0027] Therefore, refer to Figures 1 to 3 An embodiment of the present application provides an oil collecting bottle 100, which is arranged on a pitch bearing of a wind turbine. The oil collecting bottle 100 includes a plurality of splicing parts 110, which are fixed by a fixing part 120 and can be detachably combined into the oil collecting bottle 100 along the axial direction of the oil collecting bottle 100.
[0028] Specifically, if Figure 1 As shown, compared with the existing oil collecting bottle, the oil collecting bottle 100 provided in the embodiment of the present application is spliced together by multiple splicing parts 110, and is fixed by a fixing part 120, and is detachably assembled into the oil collecting bottle 100 along the axial direction of the oil collecting bottle 100, that is, it is assembled into the oil collecting bottle 100 along the vertical direction when the oil collecting bottle 100 is placed on a horizontal plane. Therefore, when it is necessary to clean the waste oil in the oil collecting bottle 100, it is only necessary to release the fixing part 120 to separate the oil collecting bottle 100. The operator can clean the waste oil in the oil collecting bottle 100 by wearing protective gloves. There is no need to clean the waste oil in the oil collecting bottle 100 through the narrow bottle mouth, that is, it can provide sufficient cleaning space, thereby improving the cleaning efficiency of the oil collecting bottle 100 and ensuring that the oil collecting bottle 100 is thoroughly cleaned.
[0029] Further, refer to Figure 1 In some embodiments of the present application, the fixing portion 120 is a clamp 120 , which surrounds the joints of the multiple splicing portions 110 to fix the multiple splicing portions 110 .
[0030] Specifically, the clamp 120 surrounds the joints of the multiple splicing parts 110 to fix the multiple splicing parts 110 to form the oil collecting bottle 100. The clamp 120 has a simple structure and is easy to install and disassemble. When the waste oil in the oil collecting bottle 100 needs to be cleaned, it is only necessary to release the clamp 120 to separate the oil collecting bottle 100. The operator can clean the waste oil in the oil collecting bottle 100 by wearing protective gloves. There is no need to clean the waste oil in the oil collecting bottle 100 through the narrow bottle mouth, that is, it can provide sufficient cleaning space, thereby improving the cleaning efficiency of the oil collecting bottle 100 and ensuring that the oil collecting bottle 100 is thoroughly cleaned.
[0031] It should be noted that the oil collecting bottle 100 provided in the embodiment of the present application can also be fixed by other fixing methods, for example, the first splicing part 111 and the second splicing part 112 are connected together by threaded fitting, or the fixing part 120 can also adopt a method other than a clamp, such as a snap-fit method through a snap-fit part.
[0032] Further, refer to Figure 1 and Figure 2 In some embodiments of the present application, the splicing portion 110 includes a first splicing portion 111 and a second splicing portion 112, a first lug 113 is provided at the bottom edge of the first splicing portion 111, and a second lug 114 is provided at the bottom edge of the second splicing portion 112, and the clamp 120 surrounds the first lug 113 of the first splicing portion 111 and the second lug 114 of the second splicing portion 112, so that the first splicing portion 111 and the second splicing portion 112 are fixed to form the oil collecting bottle 100.
[0033] like Figure 1 and Figure 2 As shown, the function of the first lug 113 of the first splicing part 111 and the second lug 114 of the second splicing part 112 is to thicken and strengthen the splicing part of the bottle body of the oil collecting bottle 100, and the clamp 120 surrounds the first lug 113 of the first splicing part 111 and the second lug 114 of the second splicing part 112, so that the first splicing part 111 and the second splicing part 112 can be effectively fixed and sealed, thereby forming the oil collecting bottle 100.
[0034] Further, refer to Figure 2 In some embodiments of the present application, the first lug 113 of the first splicing portion 111 is provided with a protrusion 115 toward the bottom surface of the second splicing portion 112, and the second lug 114 of the second splicing portion 112 is provided with a groove 116 toward the top surface of the second splicing portion 112. The first lug 113 of the first splicing portion 111 is connected to the second lug 114 of the second splicing portion 112 through the cooperation of the protrusion 115 and the groove 116.
[0035] Specifically, when assembling the oil collecting bottle 100, the first joint portion 111 and the second joint portion 112 are first assembled together, and the protrusion 115 on the first lug 113 of the first joint portion 111 is engaged with the groove 116 on the second lug 114 of the second joint portion 112, thereby forming the oil collecting bottle 100. In other words, the joint surface of the first joint portion 111 and the second joint portion 112 adopts a groove and protrusion design, which ensures the sealing of the oil collecting bottle 100 and prevents leakage of waste oil.
[0036] Furthermore, in some embodiments of the present application, the first splicing portion 111 , the first lug 113 and the protrusion 115 are an integrally formed structure, and the second splicing portion 112 , the second lug 114 and the groove 116 are an integrally formed structure.
[0037] That is, the first splicing part 111, the first lug 113 and the raised part 115 are usually structures integrally formed of metal material or plastic through a casting or injection molding process, and the second splicing part 112, the second lug 114 and the groove 116 are also the same. Therefore, the oil collecting bottle 100 provided in the embodiment of the present application has a simple structure and low manufacturing cost.
[0038] Furthermore, in some embodiments of the present application, the first lug 113 of the first splicing portion 111 is provided with a groove toward the bottom surface of the second splicing portion 112, and the second lug 114 of the second splicing portion 112 is provided with a protrusion toward the top surface of the first splicing portion 111, and the first lug 113 of the first splicing portion 111 is connected to the second lug 114 of the second splicing portion 112 through the cooperation of the protrusion and the groove.
[0039] Of course, the positions of the protrusions and / or grooves can be interchanged. That is, the first lug 113 of the first splicing portion 111 is provided with a groove toward the bottom surface of the second splicing portion 112, and the second lug 114 of the second splicing portion 112 is provided with a protrusion toward the top surface of the first splicing portion 111. The first lug 113 of the first splicing portion 111 is connected to the second lug 114 of the second splicing portion 112 through the engagement of the protrusion and the groove. The groove and protrusion design of the splicing surfaces of the first splicing portion 111 and the second splicing portion 112 ensures the sealing of the oil collecting bottle 100 and prevents leakage of waste oil.
[0040] Furthermore, in some embodiments of the present application, the first splicing portion 111 , the first lug 113 and the groove are an integrally formed structure, and the second splicing portion 112 , the second lug 114 and the protrusion are an integrally formed structure.
[0041] That is, the first splicing part 111, the first lug 113 and the groove are usually structures integrally formed of metal material or plastic through a casting or injection molding process, and the second splicing part 112, the second lug 114 and the protrusion are also the same. Therefore, the oil collecting bottle 100 provided in the embodiment of the present application has a simple structure and low manufacturing cost.
[0042] Furthermore, in some embodiments of the present application, the clamp 120 includes a locking portion and two semicircular clamps 121 . The semicircular clamps 121 are movably connected to form the clamp 120 , and the locking portion is used to lock the two semicircular clamps 121 .
[0043] Furthermore, in some embodiments of the present application, the splicing portion 110 also includes a third splicing portion 117, the second splicing portion 112 is arranged between the first splicing portion 111 and the third splicing portion 117, and the clamp 120 includes a first clamp and a second clamp, the first clamp fixes the first splicing portion 111 and the second splicing portion 112, and the second clamp fixes the second splicing portion 112 and the third splicing portion 117.
[0044] Specifically, according to actual usage requirements, the oil collecting bottle 100 can adopt a three-section structure, that is, the splicing part 110 also includes a third splicing part 117, and the second splicing part 112 is arranged between the first splicing part 111 and the third splicing part 117, thereby increasing the bottle capacity of the oil collecting bottle 100 and improving the ability of the oil collecting bottle 100 to collect waste oil.
[0045] It is understandable that the number of the splicing parts 110 of the oil collecting bottle 100 can be four or more, and the specific number depends on the actual situation and is not limited here.
[0046] Further, refer to Figure 1 and Figure 3 In some embodiments of the present application, the first splicing portion 111 is provided with a bottle mouth 118 , and the bottle mouth 118 includes a threaded portion for fixing to a pitch bearing of a wind turbine.
[0047] Specifically, the oil collecting bottle 100 is fixed to the pitch bearing of the wind turbine through the threaded portion of the bottle mouth 118, so that the waste oil in the pitch bearing can be collected into the oil collecting bottle 100 through the bottle mouth 118, thereby preventing the waste oil from leaking out and concentrating the waste oil in the oil collecting bottle 100 for subsequent cleaning.
[0048] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
