Description

Technical Field

[0001] The utility model relates to an oil collecting bottle, in particular to an oil collecting bottle used for a wind turbine variable pitch bearing. Background Art

[0002] For the variable pitch bearings of wind turbines, the main method currently adopted is to continuously add new grease and then discharge the old grease from the oil drain hole to achieve the lubrication of the variable pitch bearings and the renewal of the raceway grease. The oil collecting bottle is a container installed on the variable pitch bearing to collect the discharged waste grease.

[0003] The bottle cap and the bottle body of the oil collecting bottle are connected by threads. However, in view of the working conditions of the wind turbine, the oil collecting bottle will rotate with the hub in the wind turbine. Due to the influence of external forces such as centrifugal force and wind turbine vibration, the threaded connection between the bottle body and the bottle cap will become loose. As the wind turbine runs for a long time, the bottle body of the oil collecting bottle may be completely separated from the bottle cap, and the bottle body may fall off. The fallen bottle body may hit the mechanical and electrical components in the hub. At the same time, due to the falling of the oil collecting bottle, the waste grease discharged from the oil outlet cannot be collected, and the overflowing waste oil will contaminate the mechanical and electrical components in the hub, and also pollute the environment. Utility Model Content

[0023] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0024] The terms "above", "below", "upward" and "downward" in the present invention represent upper and lower positional relationships, but are not limited to vertical above and vertical below. Those skilled in the art can understand that obliquely above and obliquely below both belong to the scope of "above" and "below" in the present invention, and obliquely upward and obliquely downward both belong to the scope of "upward" and "downward" in the present invention.

[0025] The technical problem solved by the present invention can be achieved by adopting the following preferred implementation modes.

[0026] In order to solve the above technical problems, the utility model provides an oil collecting bottle with a locking device. Figure 1 , 2 As shown in Figures 3 and 4, the oil collecting bottle includes a bottle body 1, a bottle cap 2, a connecting piece 3, a connecting rod 4 and a base 5. The bottle mouth of the bottle body 1 is provided with a bottle body external thread 1-2, and the inner wall of the bottle cap 2 is provided with a bottle cap internal thread 2-2. The bottle body 1 and the bottle cap 2 are connected together through the bottle body external thread 1-2 and the bottle cap internal thread 2-2. The bottle cap 2 is provided with an oil drain nozzle 2-1, and the oil drain nozzle 2-1 includes a light hole 2-1-2, an external thread 2-1-1 and a nut 2-1-3. The waste grease discharged from the variable pitch bearing enters the bottle body of the oil collecting bottle through the light hole 2-1-2 of the oil drain nozzle 2-1, and the nut 2-1-3 is fixed to the oil drain nozzle 2-1 as a whole. The external thread 2-1-1 of the oil drain nozzle is used to connect with the internal thread of the variable pitch bearing, so that the oil collecting bottle can be fixed to the variable pitch bearing. As shown Figure 3 , 4 As shown, the base 5 is sleeved on the bottom of the bottle body 1, and the connecting rod 4 connects the connecting piece 3 and the base 5 together. When the oil collecting bottle is subjected to external force, the bottle body 1 will not be separated from the bottle cap 2. An exhaust pipe 1-1 is also provided at the bottom of the bottle body 1 to ensure that the bottle is connected to the outside.

[0027] Further, if Figure 5 As shown, the connecting piece 3 is in a strip shape, and has a central fixing circular hole 3-3 and a first connecting circular hole 3-1 and a second connecting circular hole 3-2 located on both sides of the fixing circular hole. Figure 2 The fixing circular hole 3-3 of the connecting piece 3 can pass through the oil discharge nozzle 2-1, and the oil discharge nozzle 2-1 and the connecting piece 3 are fixed to the bottle cap 2 by tightening the nut 2-1-4.

[0028] like Figure 6As shown, the base 5 includes a central circular hole 5-3 and a peripheral wall 5-4 surrounding the central circular hole 5-3. The central circular hole 5-3 ensures that the exhaust pipe 1-1 of the bottle body 1 (see Figure 1 ) can be exhausted normally, the peripheral wall 5-4 forms a recessed portion for accommodating the bottle body 1, and a first base connecting circular hole 5-1 and a second base connecting circular hole 5-2 are respectively provided on both sides of the peripheral wall 5-4.

[0029] like Figure 7 As shown, the connecting rod 4 has an upper circular hole 4-1 and a lower hook 4-2, and a pair of connecting rods 4 connect the connecting piece 3 and the base 5 on both sides of the bottle body 1. Furthermore, the upper circular hole 4-1 and the lower hook 4-2 are both elastic, and can be opened to a certain extent by force, so that they can be passed through the connecting circular holes 3-1, 3-2 of the connecting piece 3 and the connecting circular holes 5-1, 5-2 of the base, similar to a key passing through a keychain. When the base 5 is put on the bottom of the bottle body 1 and the bottle cap 2 is completely screwed with the bottle body 1, the upper circular hole 4-1 of one connecting rod is connected to the first connecting circular hole 3-1 of the connecting piece 3, and the lower hook 4-2 is connected to the first base connecting circular hole 5-1 of the base 5; the upper circular hole 4-1 of the other connecting rod is connected to the second connecting circular hole 3-2 of the connecting piece 3, and the lower hook 4-2 is connected to the second base connecting circular hole 5-2 of the base 5. After assembly, the oil collecting bottle is as follows Figure 3 , 4 The base 5 is made of elastic material, such as rubber, and has a certain elasticity. When the connecting rod 4 connects the connecting piece 3 and the base 5, the base 5 will generate a certain pulling force, thereby ensuring that the connection between the connecting rod 4 and the connecting piece 3 is firm and reliable. When the oil collecting bottle is subjected to external force, the bottle body 1 will not be separated from the bottle cap 2.

[0030] Compared with the traditional oil collecting bottle, the utility model has the following beneficial effects: the structure is simple, and no complicated changes are needed to the original oil collecting bottle appearance structure, that is, the bottle cap and the bottle body of the oil collecting bottle are firmly connected, and the bottle body is prevented from falling off due to external forces such as centrifugal force and fan vibration, causing waste grease to flow out and pollute the product and the environment. The variable pitch bearing using the new oil collecting bottle will not pollute the mechanical or electrical components in the variable pitch bearing due to the leakage of waste grease, thereby ensuring the performance of the bearing and increasing the service life.
