Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of power equipment, and in particular to an oil collecting bottle and a wind turbine. Background Art
[0002] The pitch system of a wind turbine is usually lubricated with lubricating oil, and multiple oil collecting bottles are usually set on the pitch bearing. The waste oil produced by the pitch bearing will enter the oil collecting bottle through the oil drain pipe, and the waste oil will be transported to the bottom of the oil collecting bottle through the oil drain pipe.
[0003] At present, with the large-scale wind turbines, the discharge of grease waste oil from the rotating support increases, and the body of the oil collecting bottle also gradually increases, so it is becoming increasingly difficult to fix the body of the oil collecting bottle, which will lead to oil leakage. Utility Model Content
[0004] The main purpose of the embodiment of the present application is to provide an oil collecting bottle, which can increase the adsorption area of the oil collecting bottle body by adding a magnetic suction part on the side wall of the bottle body to ensure that the oil collecting bottle can be stably fixed on the variable pitch bearing of the wind turbine.
[0005] To achieve the above-mentioned purpose, an embodiment of the present application provides an oil collecting bottle, which is arranged on the variable pitch bearing of a wind turbine. The oil collecting bottle includes a bottle body and a magnetic part. A slot is provided on the side wall of the bottle body, and the magnetic part is detachably arranged in the slot.
[0006] Furthermore, the slot is a hollow structure, and the slot extends along the axis of the bottle body of the oil collecting bottle.
[0007] Furthermore, a socket is provided at the bottom of the slot, and the magnetic portion is in a long strip shape. The magnetic portion is detachably accommodated in the slot through the socket of the slot.
[0008] Furthermore, it also includes a connector, one end of which is connected to the bottle mouth of the oil collecting bottle, and the other end of which is connected to the oil discharge port on the variable pitch bearing of the wind turbine.
[0009] Furthermore, the joint is a right-angle joint, which includes a main body, a first connecting part and a second connecting part. The first connecting part is arranged on the side wall of the main body, and the first connecting part is connected to the bottle mouth of the oil collecting bottle. The second connecting part is arranged at the end of the main body, and the second connecting part is provided with a threaded interface for fixed connection with the oil drain port on the variable pitch bearing of the wind turbine.
[0010] Furthermore, the main body, the first connecting portion and the second connecting portion of the right-angle joint are an integrally formed structure.
[0011] Furthermore, it also includes a bottle cap, which is detachably arranged at the bottle mouth of the oil collecting bottle, and the bottle cap is provided with a hole for the first connecting part of the connector to pass through.
[0012] Furthermore, it also includes an exhaust hole, which is arranged at the bottom of the bottle body.
[0013] In a second aspect, an embodiment of the present application further provides a wind turbine, comprising an oil collecting bottle as described in any one of the above items.
[0014] Furthermore, there are multiple oil collecting bottles, and the multiple oil collecting bottles are arranged around the variable pitch bearing of the wind turbine.
[0015] Compared with the existing oil collecting bottle, in the oil collecting bottle provided in the embodiment of the present application, the magnetic attraction part is accommodated in a slot on the side wall of the bottle body of the oil collecting bottle. The oil collecting bottle can be adsorbed on the metal variable pitch bearing of the wind turbine through the magnetic attraction part, thereby enhancing the fixed support of the oil collecting bottle and increasing the force-bearing surface between the oil collecting bottle and the metal variable pitch bearing of the wind turbine. When the wind turbine impeller rotates at high speed and there is a lot of waste oil in the oil collecting bottle, it can play an adsorption and fixing role to prevent the oil collecting bottle from falling off and being damaged under the action of the rotating centrifugal force.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Therefore, refer to Figures 1 to 3 An embodiment of the present application provides an oil collecting bottle 100, which is arranged on a variable pitch bearing 10 of a wind turbine. The oil collecting bottle 100 includes a bottle body 110 and a magnetic portion 120. A slot 130 is provided on the side wall of the bottle body 110, and the magnetic portion 120 is detachably arranged in the slot 130.
[0029] Specifically, in the oil collecting bottle 100 provided in the embodiment of the present application, the magnetic portion 120 is accommodated in the slot 130 on the side wall of the bottle body 110 of the oil collecting bottle 100. The oil collecting bottle 100 can be adsorbed on the metal variable pitch bearing of the wind turbine through the magnetic portion 120, thereby strengthening the fixed support of the oil collecting bottle 100 and increasing the force-bearing surface between the oil collecting bottle 100 and the metal variable pitch bearing of the wind turbine. When the wind turbine impeller rotates at high speed and there is a lot of waste oil in the oil collecting bottle 100, it can play a role in adsorption and fixation, preventing the oil collecting bottle 100 from falling off and being damaged under the action of the centrifugal force of rotation. Therefore, the oil collecting bottle 100 provided in the embodiment of the present application, by adding the magnetic portion 120 on the side wall of the bottle body 110, can increase the adsorption area of the oil collecting bottle 100, thereby ensuring that the oil collecting bottle 100 can be stably fixed on the variable pitch bearing of the wind turbine.
[0030] Furthermore, as described above, the oil collecting bottle 100 provided in the embodiment of the present application has a simple structure and is easily customizable. Furthermore, the magnetic portion 120 is easily removable and reusable. When the blower unit needs to be repaired and the waste oil in the bottle needs to be cleaned, the magnetic portion 120 can simply be removed, thoroughly cleaned, and then reinserted into the slot 130 for reuse.
[0031] It should be noted that the magnetic attraction portion 120 is usually made of a neodymium iron boron magnet, which can provide a large magnetic attraction force, so that the oil collecting bottle 100 can be firmly adsorbed on the pitch bearing of the wind turbine.
[0032] It can be understood that the oil collecting bottle 100 provided in the embodiment of the present application is not only suitable for collecting waste oil in situations such as variable pitch and rotating support of wind turbine sets, but can also be used for collecting lubricating waste grease in spare oil tanks of other rotating equipment, and other large and medium-sized rotating support equipment in construction, machinery, and chemical industries to avoid leakage of waste oil and environmental pollution.
[0033] Furthermore, in some embodiments of the present application, the slot 130 is a hollow structure, and the slot 130 extends along the axis of the bottle body 110 of the oil collecting bottle 100 .
[0034] Specifically, refer to Figure 1 and Figure 2 The slot 130 is used to accommodate the magnetic portion 120, which extends along the axial direction of the bottle body 110 of the oil collecting bottle 100, thereby increasing its internal space, thereby increasing the adsorption surface between the magnetic portion 120 and the pitch bearing of the wind turbine. When the wind turbine impeller rotates at high speed and there is a lot of waste oil in the oil collecting bottle 100, it can further adsorb and fix the oil collecting bottle 100 to prevent it from falling off or being damaged under the action of the centrifugal force of rotation.
[0035] Further, refer to Figures 1 to 3In some embodiments of the present application, a socket 131 is provided at the bottom of the slot 130 , and the magnetic portion 120 is in a long strip shape. The magnetic portion 120 can be detachably accommodated in the slot 130 through the socket of the slot 130 .
[0036] like Figures 1 to 3 As shown, the magnetic portion 120 is elongated, matching the shape of the slot 130. The magnetic portion 120 can be inserted into the slot 130 through the socket 131 at the bottom of the oil collecting bottle 100. This increases the adhesion between the bottle body 110 of the oil collecting bottle 100 and the wind turbine's pitch bearing, preventing the oil collecting bottle 100 from falling off or being damaged by the centrifugal force of rotation. Furthermore, when the wind turbine unit needs to be repaired and the waste oil in the bottle needs to be cleaned, the magnetic portion 120 can be simply removed from the slot 130, thoroughly cleaned, and then reinserted into the slot 130 through the socket for reuse.
[0037] Further, refer to Figure 2 In some embodiments of the present application, the oil collecting bottle 100 further includes a connector 140, one end of which is connected to the bottle opening of the oil collecting bottle 100, and the other end of which is connected to the oil drain port on the pitch bearing 10 of the wind turbine. Figure 2 As shown, the function of the connector 140 is to guide the waste oil in the variable pitch bearing of the wind turbine from the oil drain port into the oil collecting bottle 100 to collect the waste oil and prevent the waste oil from leaking and contaminating the wind turbine.
[0038] Further, refer to Figures 1 to 3 In some embodiments of the present application, the joint 140 is a right-angle joint, which includes a main body 141, a first connecting part 142 and a second connecting part 143. The first connecting part 142 is arranged on the side wall of the main body 141, and the first connecting part 142 is connected to the bottle mouth of the oil collecting bottle 100. The second connecting part 143 is arranged at the end of the main body 141, and the second connecting part 143 is provided with a threaded interface 144 for fixed connection with the oil drain port on the pitch bearing 10 of the wind turbine.
[0039] Therefore, through the above-mentioned setting, the right-angle joint 140 can be stably fixed on the pitch bearing 10 of the wind turbine, and the waste oil in the pitch bearing 10 can pass through the oil drain port and enter the oil collecting bottle 100 via the second connecting part 143, the main body 141 and the first connecting part 142, thereby preventing the oil collecting bottle 100 from falling off and preventing the waste oil from leaking out.
[0040] Furthermore, in some embodiments of the present application, the main body 141 , the first connection portion 142 , and the second connection portion 143 of the right-angle joint 140 are an integrally formed structure.
[0041] That is, the right-angle joint 140 is usually made of metal or plastic material, and its main body 141, first connecting part 142 and second connecting part 143 are structures integrally formed of metal or plastic material by casting or injection molding. Therefore, the oil collecting bottle 100 provided in the embodiment of the present application has a simple structure and low manufacturing cost.
[0042] Further, refer again to Figures 1 to 3 In some embodiments of the present application, the oil collecting bottle 100 further includes a bottle cap 150, which is detachably disposed at the bottle mouth of the oil collecting bottle 100, and the bottle cap 150 is provided with a hole for the first connecting portion 142 of the connector 140 to pass through.
[0043] Specifically, bottle cap 150 is used to connect connector 140 to body 110 of oil collection bottle 100, thereby ensuring that waste oil discharged from the wind turbine's pitch bearing 10 is collected in oil collection bottle 100, preventing waste oil leakage and environmental pollution. Bottle cap 150 is provided with a hole for the first connecting portion 142 of connector 140 to pass through. This hole is generally located in the center of bottle cap 150, and its diameter matches the outer diameter of the first connecting portion 142 of connector 140, allowing the first connecting portion 142 to pass through and be stably fixed within the hole.
[0044] Further, refer to Figure 1 and Figure 2 In some embodiments of the present application, the oil collecting bottle 100 further includes an exhaust hole 160, which is provided at the bottom of the bottle body 110. The exhaust hole 160 is used to balance the internal and external pressures of the oil collecting bottle 100, so that the waste oil can be smoothly collected into the oil collecting bottle 100.
[0045] In addition, an embodiment of the present application further provides a wind turbine including the oil collecting bottle 100 described above. The specific structure of the oil collecting bottle 100 is similar to that of the above embodiments. Since the oil collecting bottle 100 utilizes all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0046] Further, refer to Figure 4 In some embodiments of the present application, multiple oil collecting bottles 100 are provided, each of which is disposed around the wind turbine's pitch bearing 10. Therefore, waste oil within the wind turbine's pitch bearing 10 can be evenly discharged into the multiple oil collecting bottles 100 under the centrifugal force of rotation, allowing for timely collection of the waste oil to prevent leakage and environmental pollution.
[0047] 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.
