Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to an electric pump and filter mounting bracket and a wind power generator set. Background Art

[0002] The gearbox in a wind turbine is a crucial mechanical component, its primary function being to transmit the wind-driven power generated by the rotor to the generator, ensuring a corresponding rotational speed. Installed in windy locations such as high mountains, wilderness, beaches, and islands, the turbines are subject to irregular winds of varying direction and load, as well as strong gusts. They are constantly exposed to extreme heat and cold, as well as temperature swings. Furthermore, these environments are often difficult to access, and the gearbox is housed in a confined space atop the tower. Failures can be extremely difficult to repair, placing significantly higher demands on its reliability and service life than typical machinery.

[0003] As a transmission system, the gearbox should not only have conventional mechanical properties but also provide excellent lubrication and cooling conditions during use. The lubrication and cooling system mainly consists of an oil supply device, a filter device, an air cooling device, an overflow valve assembly, a temperature control valve assembly, a main distribution valve block, a pressure sensor, a pressure gauge, and connecting pipes. The oil supply device includes an electric pump and a mechanical pump, which pass the lubricating oil inside the gearbox through a two-stage filter device and an oil distributor into the gearbox's lubrication and cooling pipes. The overflow valve assembly ensures that the system oil pressure does not exceed the set value. The temperature control valve assembly can control whether the oil flows through the cooler according to the oil temperature. The control system can control the low and high speed rotation of the oil pump motor and the cooler fan motor according to the temperature of the oil pool.

[0004] Currently, most gearbox lubrication systems in the wind power industry are mounted on the gearbox via brackets. In particular, the electric pump and filter are typically installed on the side or rear of the gearbox housing. The electric pump is connected to the lubrication pump motor and gear pump via a coupling. During unit operation or when exposed to severe wind conditions, the nacelle experiences significant vibration or oscillation. Furthermore, the gearbox itself vibrates during operation, and the electric pump and filter mounted on the gearbox housing generate even more intense vibrations. Therefore, ensuring the stability of the gearbox's lubrication system, including the electric pump and filter, plays a crucial role in ensuring the proper operation of the unit.

[0005] The structural defects of the electric pump and filter mounting bracket in the current wind turbine are as follows:

[0006] The electric pump and filter brackets were not strong enough. When wind farm maintenance personnel were working on the gearbox, they often stepped on the lubrication pump motor, causing excessive stress on the brackets.

[0007] The electric pump is rigidly connected to the box. During operation, the vibration of the electric pump and the box affects the stability of the electric pump installation;

[0008] In the traditional structure, when the lubrication pump motor in the electric pump is damaged, the replaced electric pump will be loose in the engagement position with the housing, resulting in poor concentricity between the electric pump output shaft and the coupling, causing wear of the bearing chamber at the drive end of the electric pump, bearing runaway, and worn grooves in the bearing chamber that eat into the motor air gap to form a bore scraping, ultimately damaging the electric pump. Utility Model Content

[0009] The purpose of the utility model is to provide an electric pump and filter mounting bracket and a wind turbine generator set, aiming to solve the problems of insufficient strength of the mounting bracket of the electric pump and filter and poor vibration elimination effect in traditional wind turbine generator sets.

[0010] In order to solve the above problems, the first aspect of the present invention provides an electric pump and filter mounting bracket, wherein the mounting bracket is used to fix the electric pump and filter to a wind turbine generator set;

The second mounting plate is separated from the gearbox housing by a first distance. A first buffer member is provided on the side of the second mounting plate close to the gearbox housing. The filter is fixedly mounted on the first mounting plate, and the electric pump is fixedly mounted on the second mounting plate.

[0013] Preferably, a second bent plate is provided on the first mounting plate, and the filter is fixedly mounted on the second bent plate.

[0014] Preferably, the mounting bracket further includes a reinforcing member, and the reinforcing member is arranged on a side of the first mounting plate away from the gear box housing.

[0016] Preferably, a first mounting hole is provided on the second mounting plate, and a first bolt is provided in conjunction with the first mounting hole, and the electric pump is fixedly mounted on the second mounting plate by the first bolt.

[0017] Preferably, the number of the first buffer members is greater than or equal to three, the first buffer members are arranged corresponding to the first mounting holes, and the first bolt passes through the first mounting hole and abuts against the first buffer member.

[0018] Preferably, a second mounting hole is provided on the second bent plate, and a second bolt is provided in conjunction with the second mounting hole, and the filter is fixedly mounted on the second bent plate by the second bolt.

[0019] Preferably, a groove is provided on a side of the second bent plate close to the filter, and the groove is in contact with the side wall of the filter.

[0022] Preferably, a second buffer member is provided on the housing of the gear box, and the second buffer member is cooperatively connected with the first buffer member.

[0023] Through such an arrangement, the electric pump and filter in the wind turbine generator set are fixedly connected to the gear box housing. By setting up a mounting bracket, the mounting strength of the electric pump and filter to the gear box housing is increased, so that the electric pump and filter are stably installed. At the same time, a gap is set between the second mounting plate for mounting the electric pump and the gear box housing, which can effectively reduce the vibration effect of the wind turbine generator set and the electric pump during operation; a first buffer member and a second buffer member are set in the gap between the second mounting plate and the gear box housing to ensure that the second mounting plate can be effectively supported while alleviating or even eliminating vibration; further, the electric pump and filter are fixed with bolts to facilitate the disassembly and maintenance of the electric pump and filter, avoid the electric pump and the housing being stiff at the engagement position, resulting in poor concentricity of the electric pump output shaft and the coupling, causing wear of the bearing chamber at the drive end of the electric pump, bearing running, and the wear groove of the bearing chamber eating up the motor air gap to form a swept bore, which ultimately leads to damage to the electric pump, etc., which is beneficial to the long-term and stable operation of the equipment.

[0038] In the description of the present invention, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0039] Combine Figures 1 to 4On the one hand, the utility model provides a mounting bracket 1, which is used to fix the electric pump 2 and the filter 3 on the wind turbine generator set. The mounting bracket 1 includes a first mounting plate 11, a second mounting plate 12 and a first bent plate 13; the first mounting plate 11 and the second mounting plate 12 are fixedly connected by the first bent plate 13, the side of the first mounting plate 11 is attached to the gear box 4 of the generator set and is fixedly connected to the gear box 4, the second mounting plate 12 is separated from the gear box 4 by a first distance, and the second mounting plate 12 is provided with a first buffer member 14 on the side of the gear box 4 close to the gear box 4. The filter 3 is fixedly mounted on the first mounting plate 11, and the electric pump 2 is fixedly mounted on the second mounting plate 12. Through such an arrangement, the mounting bracket 1 is divided into a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 is fitted with the gear box 4 housing, and the filter 3 is installed on the first mounting plate 11, which can well support the filter 3. At the same time, the filter 3 is less affected by vibration during operation, and the filter 3 itself does not vibrate. Therefore, the first mounting plate 11 fitted and fixedly connected with the gear box 4 housing can firmly fix the filter 3; the first bent plate 13 connects the first mounting plate 11 and the second mounting plate 12, and at the same time, a gap can be left between the second mounting plate 12 and the gear box 4 housing. Since the gear box 4 will have certain vibrations during the operation of the wind turbine generator set, and the electric pump 2 itself will also have certain vibrations when running, by setting a gap between the second mounting plate 12 and the gear box 4 housing, direct contact between the electric pump 2 and the gear box 4 housing is avoided, which can effectively alleviate the transmission of vibrations and mutual interference.

[0040] It should be noted that the fixing method of the first mounting plate 11 and the gear box 4 housing is not limited here, and can be bolted, clamped or welded, etc. In a preferred case, the first mounting plate 11 and the gear box 4 housing are fixed by welding, and welding is performed along the four sides of the first mounting plate 11 and the gear box 4 housing to ensure that the first mounting plate 11 and the gear box 4 housing are reliably connected, improve the installation strength of the filter 3, and avoid deformation of the mounting bracket 1 caused by stepping on or bumping during the maintenance of the wind turbine generator set, thereby affecting the fixed installation effect. The specific shape and connection position of the first mounting plate 11, the second mounting plate 12 and the first bent plate 13 are not limited, and can meet the installation strength of the electric pump 2 and the filter 3 and provide sufficient installation space. In one optional situation, one side of the first bent plate 13 is fixedly connected to one side of the first mounting plate 11, and the other side of the first bent plate 13 is fixedly connected to one side of the second mounting plate 12, so that a gap is directly maintained between the second mounting plate 12 and the gear box 4 housing; in another optional situation, the first mounting plate 11, the second mounting plate 12 and the first bent plate 13 are integrally formed, that is, an integral mounting bracket 1 is bent to form a first mounting plate 11 that fits the gear box 4 housing and a second mounting plate 12 that leaves a gap with the gear box 4 housing. Through the integrated setting, the overall strength and support effect of the mounting bracket 1 can be guaranteed. In a preferred situation, the second mounting plate 12 and the gear box 4 housing are in a parallel state, which is conducive to the installation and use of the first buffer member 14. The specific form of the first buffer member 14 and the connection method of the first buffer member 14 and the second mounting plate 12 are not limited here. Rubber, plastic or high-strength springs can be used. The first buffer member 14 can be bonded, threaded or clamped to the second mounting plate 12.

[0041] In addition, the specific installation method of the first mounting plate 11 and the filter 3 is not limited here. It can be a metal ring provided on the first mounting plate 11, and the filter 3 is fixed to the first mounting plate 11 through the metal ring, or it can be fixed by bolts, or by providing matching buckles on the first mounting plate 11 and the filter 3, and fixing them by snap connection, so that the filter 3 can be firmly installed on the first mounting plate 11. Figure 1 In a preferred embodiment, a second bent plate 15 is provided on the first mounting plate 11 to securely mount the filter 3. Considering that the filter 3 needs to maintain a vertical filtering orientation during operation to facilitate smooth filtration, the second bent plate 15 is provided on one side of the first mounting plate 11. This second bent plate 15 secures the filter 3 and provides a good filtration orientation for the filter 3.

[0042] The fixing method of the second bending plate 15 and the filter 3 is not limited here. Figure 1 and Figure 4In a preferred embodiment, a second mounting hole 15a is provided on the second bent plate 15, and a second bolt 18 is provided in conjunction with the second mounting hole 15a. The filter 3 is fixedly mounted on the second bent plate 15 by the second bolt 18. The specific number of the second mounting holes 15a is not limited here. The number of the second bolts 18 corresponds to the number of the second mounting holes 15a, and the filter 3 can be fixed on the second bent plate 15. Furthermore, a groove 15b is provided on the side of the second bent plate 15 close to the filter 3, and the groove 15b is in contact with the side wall of the filter 3. Through such a setting, during the connection process between the filter 3 and the second bent plate 15, the groove 15b of the second bent plate 15 can support the filter 3, reduce the shear force and torque at the connection between the second bolt 18 and the second bent plate 15, and make the installation of the filter 3 more stable.

[0043] The specific installation method of the second mounting plate 12 and the electric pump 2 is not limited here. Similar to the installation method of the filter 3, a metal ring can be set on the second mounting plate 12 to fix the electric pump 2 through the metal ring, or it can be fixed by bolts or buckles. Figure 1 and Figure 4 In a preferred embodiment, the second mounting plate 12 is provided with a first mounting hole 12a, and a first bolt 17 is provided in conjunction with the first mounting hole 12a. The electric pump 2 is fixedly mounted to the second mounting plate 12 via the first bolt 17. Furthermore, the number of first buffer members 14 is greater than or equal to three, and each first buffer member 14 is provided corresponding to the first mounting hole 12a. The first bolt 17 passes through the first mounting hole 12a and abuts against the first buffer member 14. With this arrangement, the electric pump 2 is fixedly connected to the second mounting plate 12 via the first bolt 17. The first buffer members 14 are provided corresponding to the first mounting holes 12a, and there are greater than or equal to three first buffer members 14. During operation, the vibration energy of the electric pump 2 and the gearbox 4 is primarily released through the first buffer members 14. At the same time, the first buffer members 14 correspond to the first mounting holes 12a and the first bolts 17, effectively reducing the impact of vibration on the first bolts 17, ensuring that each first bolt 17 is always tightened, and guaranteeing the installation effect of the electric pump 2.

[0044] Combine Figure 1In a preferred embodiment, the mounting bracket 1 further comprises a reinforcing member 16, which is arranged on a side of the first mounting plate 11 away from the gearbox 4 housing. The reinforcing member 16 further enhances the overall strength of the first mounting plate 11. The connection method between the reinforcing member 16 and the first mounting plate 11 is not limited here. Preferably, the reinforcing member 16 is welded to the first mounting plate 11, which saves costs and facilitates operation. The specific structure of the reinforcing member 16 is also not limited. In a preferred embodiment, the reinforcing member 16 comprises a first reinforcing plate 161 and a second reinforcing plate 162. One end of the first reinforcing plate 161 abuts against the second reinforcing plate 162, the other end of the first reinforcing plate 161 is fixedly connected to the second bent plate 15, and one end of the second reinforcing plate 162 is fixedly connected to the first bent plate 13. Through such an arrangement, the first reinforcing plate 161 and the second bent plate 15 are fixedly connected, which can enhance the strength of the first mounting plate 11 and the second bent plate 15. The second reinforcing plate 162 is fixedly connected to the first bent plate 13, which can enhance the strength of the first mounting plate 11 and the first bent plate 13. In a preferred embodiment, both the first reinforcing plate 161 and the second reinforcing plate 162 are welded to the first mounting plate 11, with one end of the first reinforcing plate 161 welded to the second bent plate 15, and the first end of the second reinforcing plate 162 welded to the first bent plate 13. This arrangement improves the overall stability of the mounting bracket 1. The specific number of first and second reinforcing plates 161, 162 is not limited, as long as the overall strength of the mounting bracket 1 meets the requirements.

[0045] Combine Figures 1 to 4Another aspect of the present invention provides a wind turbine generator set, including a mounting bracket 1, an electric pump 2, a filter 3 and a gear box 4; the electric pump 2 and the filter 3 are fixedly connected to the housing of the gear box 4 through the mounting bracket 1. By such an arrangement, the electric pump 2 and the filter 3 in the wind turbine generator set are fixedly connected to the gear box 4 housing. By providing the mounting bracket 1, the mounting strength of the electric pump 2 and the filter 3 to the gear box 4 housing is increased, so that the electric pump 2 and the filter 3 are stably installed. At the same time, a gap is provided between the second mounting plate 12 for mounting the electric pump 2 and the gear box 4 housing, which can effectively reduce the vibration effect of the wind turbine generator set and the electric pump 2 during operation; a first buffer member 14 is provided in the gap between the second mounting plate 12 and the gear box 4 housing to ensure that the second mounting plate 12 can be effectively supported while reducing or even eliminating vibration; further, the electric pump 2 and the filter 3 are fixed with bolts to facilitate the disassembly and maintenance of the electric pump 2 and the filter 3, avoid the electric pump 2 and the housing from being stiff at the engagement position, resulting in poor concentricity of the output shaft of the electric pump 2 and the coupling, causing wear of the bearing chamber at the drive end of the electric pump 2, bearing running, and the wear groove 15b of the bearing chamber eating up the motor air gap to form a swept bore, which ultimately leads to damage to the electric pump 2, etc., which is conducive to the long-term and stable operation of the equipment. In an optional situation, the mounting bracket 1 , the filter 3 and the electric pump 2 are used for the lubrication and cooling system of the wind turbine gearbox 4 to ensure the safe and stable operation of the gearbox 4 .

[0046] In a preferred embodiment, a second buffer member 41 is provided on the housing of the gearbox 4, and the second buffer member 41 is connected to the first buffer member 14. By providing the second buffer member 41, the vibration effect between the gearbox 4 and the electric pump 2 can be further reduced. The specific connection relationship and size of the first buffer member 14 and the second buffer member 41 are not limited here. The first buffer member 14 and the second buffer member 41 of the same size can be overlapped, or the size of the second buffer member 41 can be larger than the size of the first buffer member 14. In this case, one side of the first buffer member 14 can be embedded in the second buffer member 41 to improve the connection strength between the first buffer member 14 and the second buffer member 41, while ensuring that the first buffer member 14 and the second buffer member 41 do not move or misalign during operation.

[0047] In a wind turbine generator set, preferably, the first mounting plate 11, the second mounting plate 12, the first bent plate 13, the second bent plate 15, and the reinforcing member 16 in the mounting bracket 1 are all made of Q235B steel with a thickness of 6 mm or more, which can ensure the strength of the mounting bracket 1 during operation; during the installation of the electric pump 2, when the number of the first mounting holes 12a and the corresponding first bolts 17 is four or more, the first bolts 17 with a model of M10 or above are used to ensure the installation strength of the electric pump 2; when the number of the first mounting holes 12a and the corresponding first bolts 17 is three, in order to improve the installation strength of the electric pump 2, first bolts 17 with a higher strength than M10, such as M16, can also be used. In one embodiment of the present invention, two second mounting holes 15a are provided on the second bent plate 15, and second bolts 18 with a model of M16 or above are used to ensure the installation strength of the filter 3.

[0048] To sum up, the mounting bracket in the present invention adopts thick plate parts, which are connected to the wind turbine generator set by welding. After welding, the overall strength is high and it is not easy to be stepped on, bumped, deformed or damaged. At the same time, multiple connection points are designed to be connected to the gear box housing through the first buffer member and the second buffer member to avoid the installation of the electric pump and the filter in a cantilever state, and at the same time reduce the damage to the electric pump coupling caused by vibration and shaking during the operation of the unit. In addition, multiple connection holes are all oblong holes or through holes, which avoids the problem of stiffness in the engagement position with the housing when replacing the lubrication pump motor, resulting in a shorter life of the lubrication pump motor. The structural design is reasonable and compact, and the electric pump, filter and gear box housing do not interfere with each other, ensuring the normal and stable operation of the wind turbine gear box lubrication and cooling system.
