Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a high-efficiency adjustable hydraulic pump assembly device for a wind power system. Background Art

[0002] A high-efficiency, adjustable hydraulic pump assembly is a key component of a wind turbine. It primarily consists of a hydraulic pump, motor, and control valve. These components work together to provide adjustable hydraulic power to suit the wind turbine's operating conditions at varying wind speeds. The hydraulic pump assembly's design allows it to adjust flow and pressure based on system requirements, achieving efficient energy conversion and control.

[0003] Chinese utility model patent CN218207052U discloses a hydraulic pump controller and a hydraulic pump assembly, comprising a hydraulic pump body, wherein the oil inlet of the hydraulic pump body is fixedly connected to an oil inlet pipe, the oil outlet of the hydraulic pump body is fixedly connected to an oil outlet pipe, the right end of the oil inlet pipe is fixedly connected to a filter box, the inner wall of the filter box is respectively installed with a first filter screen plate and a second filter screen plate from right to left, and the top and bottom of the back of the filter box are fixedly connected to a short plate, one side of which is fixedly connected to a motor. This utility model solves the problem that the existing hydraulic pump system cannot clean the filter screen used for oil filtration, causing blockage after long-term use and affecting the operation of the hydraulic pump, and when the hydraulic pump is working, it generates pressure on the oil, thereby increasing the internal energy of the oil and causing the oil temperature to rise. When the oil flows back into the hydraulic pump, the temperature will also rise, which can easily cause damage to the hydraulic pump.

[0004] However, when the hydraulic oil in the existing wind power system hydraulic pump assembly is in use, magnetic impurities in the hydraulic oil cannot be absorbed during the circulation process, causing the impurities to wear the inside of the hydraulic pump assembly, thereby greatly reducing the service life of the hydraulic pump assembly. Therefore, a high-efficiency and adjustable hydraulic pump assembly device for a wind power system is needed. Utility Model Content

[0005] The utility model provides a high-efficiency adjustable hydraulic pump assembly device for a wind power system, so as to solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: A high-efficiency adjustable hydraulic pump assembly device for a wind power system, comprising a hydraulic pump assembly main body, a filter box and a magnetic screen plate, a coolant tank being fixedly installed on the top of the hydraulic pump assembly main body near the rear end, a return pipe being fixedly connected to the top of the coolant tank, a bend being provided on the hydraulic pump assembly main body, an oil inlet pipe being fixedly connected to the left side of the hydraulic pump assembly main body near the center, a sealing cover being provided on the top of the filter box, a mounting pipe being fixedly connected to the left side of the filter box, a connecting pipe being fixedly connected to the right side of the filter box, limit blocks being fixedly installed on the front and rear end walls of the interior of the filter box near the left side, a first magnetic connecting plate being fixedly installed on the front and rear end walls of the interior of the filter box near the left side, a second magnetic connecting plate being fixedly installed on the periphery of the magnetic screen plate, a plurality of limit grooves being symmetrically and evenly distributed on the front and rear ends of the interior of the filter box, and filter screen plates being movably sleeved inside the plurality of symmetrically arranged limit grooves.

[0007] Furthermore, the plurality of filter screen plates are movably connected to the interior of the plurality of limiting grooves respectively, and a sealing gasket is provided at the connection between the filter screen plates and the limiting grooves.

[0008] Furthermore, one end of the oil inlet pipe away from the filter box and one end of the oil inlet pipe away from the hydraulic pump assembly body are fixedly connected via a flange.

[0009] Furthermore, the first magnetic connecting plate is adsorbed and connected to the second magnetic connecting plate.

[0010] Furthermore, the limit blocks are symmetrically arranged, and the magnetic mesh plate is located within the angle formed by a pair of limit blocks.

[0011] Furthermore, an oil outlet pipe is provided on the right side of the hydraulic pump assembly body.

[0012] Furthermore, a refrigerator is embedded in the coolant tank.

[0013] Compared with the prior art, the present invention provides a high-efficiency and adjustable hydraulic pump assembly for a wind power system, which has the following beneficial effects:

[0014] 1. This wind power system's high-efficiency adjustable hydraulic pump assembly, equipped with a magnetic screen, can effectively absorb and intercept magnetic impurities such as iron filings and metal particles in the main body of the hydraulic pump assembly, preventing them from damaging the hydraulic pump assembly and thus extending its service life. It can also significantly improve the cleanliness of the hydraulic oil, reducing and lowering hydraulic pump assembly failures and repair costs caused by impurities.

[0015] 2. This wind power system's high-efficiency, adjustable hydraulic pump assembly utilizes first and second magnetic connection plates. Because the magnetic screen is quickly attached and connected via these plates, cleaning or replacement requires simply separating the first and second plates to easily remove the magnetic screen. This process is significantly faster than disassembling the entire hydraulic pump assembly. This rapid replacement process means the hydraulic pump assembly can be restored to operation in a shorter period of time, reducing downtime due to maintenance, which is particularly important for wind power systems that require continuous operation. The elimination of the need to disassemble the entire hydraulic pump assembly reduces the skill requirements and labor costs of maintenance personnel. Frequent disassembly and reassembly can cause unnecessary wear and tear on other components of the hydraulic pump assembly. The magnetic connection plate design minimizes this wear and tear, thereby extending the service life of the entire hydraulic pump assembly. The simple and quick replacement process eliminates the need for additional tools and materials for disassembly and reassembly, saving these costs. This not only improves maintenance efficiency but also significantly reduces maintenance costs, providing a strong guarantee for the long-term, stable operation of the hydraulic system.

[0026] Specifically, an oil outlet pipe is provided on the right side of the hydraulic pump assembly body 1 .

[0027] Specifically, a refrigerator is mounted on the coolant tank 5 .

[0028] During use, the returned hydraulic oil flows into the filter box 11 through the installation pipe 9, and then the magnetic impurities in the returned hydraulic oil are adsorbed by the magnetic screen plate 12 in the filter box 11. The hydraulic oil that has been preliminarily filtered by the magnetic screen plate 12 continues to flow through the filter screen plate 10, and the non-magnetic impurities in the hydraulic oil, such as dust and tiny particles, can be further removed by the filter screen plate 10; the hydraulic oil that has undergone double filtration becomes purer, and then flows into the oil inlet pipe 6 through the connecting pipe 7, and finally enters the interior of the hydraulic pump assembly body 1, completing a complete cycle; this circulation mechanism ensures the continuous cleanliness of the hydraulic oil and helps to extend the service life of the hydraulic system; as the use time increases, a large amount of impurities will accumulate on the magnetic screen plate 12; at this time, it is necessary to open the sealing cover 8 of the filter box 11 in order to remove the magnetic screen plate 12; the magnetic screen plate 12 is usually provided with a pair of limit blocks 1 3 is fixed and connected to each other by the first magnetic connecting plate 14 and the second magnetic connecting plate 15; when taking it out, the magnetic screen plate 12 needs to be carefully pulled out from the angle formed by the limit block 13, and the first magnetic connecting plate 14 and the second magnetic connecting plate 15 need to be separated at the same time; the removed magnetic screen plate 12 should be thoroughly cleaned to remove the adsorbed impurities; if the magnetic screen plate 12 is seriously damaged or the adsorption capacity is reduced, it is necessary to replace it with a new magnetic screen plate 12 in time, and the cleaned or replaced magnetic screen plate 12 needs to be put back into the filter box 11 and ensure that it is correctly installed in the angle formed by a pair of limit blocks 13; at this time, the first magnetic connecting plate 14 and the second magnetic connecting plate 15 will automatically be adsorbed and connected, restoring the normal working state of the magnetic screen plate 12; thereby not only effectively removing various impurities in the hydraulic oil, but also improving the maintainability and operating efficiency of the hydraulic pump assembly through convenient maintenance.
