Description

Technical Field

[0001] The invention relates to hydraulic oil heat dissipation technology, and in particular to an air-cooled oil heat dissipation device for wind power equipment. Background Art

[0002] With the gradual depletion of energy sources such as coal and oil, humans are paying more and more attention to the use of renewable energy. Wind energy, as a clean and renewable energy source, is increasingly valued by countries around the world. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that are short of water, fuel and have inconvenient transportation, it is very suitable to use wind power generation in accordance with local conditions. Under some extreme weather conditions, such as high temperature, high humidity, sandstorms and other environments, the heat dissipation capacity of the air may decrease, resulting in the inability to effectively control the lubricating oil temperature. Especially in high temperature or sandstorm weather in summer, the air cooling system may face insufficient cooling capacity.

[0003] A Chinese invention patent with publication number CN118481933A discloses an air-cooled oil heat sink for wind power equipment. The air-cooled oil heat sink for wind power equipment is provided with a refrigeration component, a heat sink component, a heat sink 1, a heat sink 2, etc. When the hydraulic oil needs to be radiated, the vacuum pump and the refrigeration box are started, and the outside air is drawn in through the vacuum hood, and then converted into cold air through the refrigeration box. The cold air enters each outlet branch pipe through the outlet main pipe and is sprayed out by the nozzle. The cold air can be evenly sprayed into the inner cavity of the box through the ventilation hole, thereby cooling the hydraulic oil inside the hydraulic oil tank. At the same time, through the cooperation of the heat dissipation fan and the heat sink 1 and the heat sink 2, a multi-directional strong air duct can be formed in the inner cavity of the box, so that the heat emitted from the hydraulic oil tank can be quickly transferred out, so that the hydraulic oil can be quickly radiated, effectively avoiding the accumulation of heat in the hydraulic oil, and playing a role in protecting the wind power equipment and extending the service life of the wind power equipment.

[0004] When the existing equipment is in use, the hydraulic oil in the hydraulic system plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. When the wind power equipment has been running for a period of time, the hydraulic oil inside the hydraulic system will gradually heat up. At this time, cooling equipment is needed to cool the hydraulic oil. Otherwise, the long-term heating of the hydraulic oil will cause the hydraulic oil to deteriorate, which is not conducive to the use of the equipment and reduces the service life of the equipment. At the same time, the hydraulic oil inside the hydraulic equipment cannot control the circulation efficiency, resulting in poor cooling effect. Therefore, an air-cooled oil heat dissipation device for wind power equipment has been developed. Summary of the invention

The outer surface of the oil barrel 1 is connected to a lead-out component 2, and the hydraulic oil after the inner wall of the oil barrel 1 is heated is led out through the lead-out component 2.

[0039] In this solution, the oil barrel 1 is arranged at the upper end of the wind power equipment, and the hydraulic oil inside the oil barrel 1 is discharged through the discharge component 2, the hydraulic oil is cooled through the pipeline, and the cooled hydraulic oil is reintroduced into the interior of the oil barrel 1 through the transmission component 3, thereby improving the overall service life.

[0041] In this embodiment, the first baffle 215 is composed of a plurality of sets of sector blocks, and a movable gap is reserved between every two sector blocks. When the rubber ball 214 fits the first baffle 215, the hydraulic oil can be discharged through the gap.

[0042] The cross section of the second baffle 216 is annular, and the outer surface of the rubber ball 214 is in contact with the inner wall of the second baffle 216 , so that the cylinder 213 is isolated from the outside.

[0043] Furthermore, a positioning block 22 is disposed at the upper end of the collecting tube 21 , and the lower end of the positioning block 22 penetrates and extends into the interior of the collecting tube 21 , while a rotating shaft 23 is rotatably mounted at the lower end of the positioning block 22 .

[0044] Specifically, a slot is provided at the lower end of the positioning block 22, and the inner wall of the slot is slidably connected to the outer surface of the rotating shaft 23. At the same time, a partition is provided at the upper end of the rotating shaft 23, and the cross-section of the partition is larger than the cross-section of the slot, thereby protecting the rotating shaft 23.

[0045] Furthermore, a slide groove 211 is provided on the inner wall of the collecting tube 21 , a rotating plate 24 is slidably mounted on the inner wall of the slide groove 211 , a gear block 25 is provided at the upper end of the rotating plate 24 , and a limit block 27 is provided at the lower end of the rotating plate 24 .

[0046] Specifically, the slide groove 211 fits with the outer surface of the rotating plate 24, thereby limiting the gear block 25 and the limit block 27. At the same time, when the gear block 25 rotates, the whole remains stable to avoid falling off during rotation.

[0047] Furthermore, a telescopic member 26 is provided on the outer surface of the collecting tube 21 , and the output end of the telescopic member 26 penetrates and extends into the interior of the collecting tube 21 . A gear plate 261 is provided on the output end of the telescopic member 26 , and the outer surface of the gear plate 261 meshes with the outer surface of the gear block 25 .

[0048] Specifically, the telescopic member 26 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 26 is started, it synchronously drives the gear plate 261 arranged at its output end to move. Since the outer surface of the gear plate 261 is meshed with the outer surface of the gear block 25, when the gear plate 261 moves, the gear block 25 is driven to rotate.

[0049] Furthermore, an arc-shaped groove 231 is provided on the outer surface of the rotating shaft 23 , and a protrusion 271 is provided on the inner wall of the limiting block 27 , and the outer surface of the protrusion 271 is slidably connected to the inner wall of the arc-shaped groove 231 .

[0050] Specifically, when the limit block 27 rotates, the protrusion 271 arranged on the inner wall of the limit block 27 is synchronously driven to rotate, wherein the outer surface of the protrusion 271 is slidably connected to the inner wall of the arc groove 231, so that when the limit block 27 rotates, the rotating shaft 23 is driven to move up and down.

[0051] Furthermore, a fixed block 29 is provided at the lower end of the rotating shaft 23, and an elastic member 28 is sleeved on the outer surface of the limit block 27, and the lower end of the elastic member 28 is connected to the upper end of the fixed block 29. A through hole 212 is opened at the lower end of the collecting cylinder 21, and the inner wall of the through hole 212 is slidably connected to the outer surface of the fixed block 29.

[0052] Specifically, when the rotating shaft 23 moves up and down, the fixed block 29 arranged at its lower end is synchronously driven to move. Since the outer surface of the fixed block 29 slides with the inner wall of the through hole 212, and when the fixed block 29 moves upward, the collecting cylinder 21 can be connected to the outside, so that the hydraulic oil can be discharged. At the same time, a filter net can be set at the lower end of the through hole 212, and impurities on the inner wall of the hydraulic oil can be removed through the filter net.

[0053] The elastic member 28 is an elastic component such as a spring, which is used to support the fixing block 29 so that the fixing block 29 will not shake when it is in contact with the through hole 212. At the same time, the outer surface of the fixing block 29 is provided with a component with a sealing effect such as rubber.

[0054] Furthermore, the transmission assembly 3 is mounted on the outer surface of the oil barrel 1, and the hydraulic oil is transported through the transmission assembly 3. The transmission assembly 3 includes a connecting tube 39 connected to the oil barrel 1, the inner wall of the connecting tube 39 is provided with a power member 31, and the output end of the power member 31 is provided with a connecting block 33.

[0055] In this embodiment, the lower end of the connecting tube 39 is connected to the through hole 212 via a cooling pipe, so that the hotter hydraulic oil in the oil barrel 1 is transmitted to the connecting tube 39 through the cooling pipe, and then enters the oil barrel 1 in turn.

[0056] The power part 31 is composed of a round rod, a sleeve and a spring, and the outer surface of the round rod is slidably connected to the inner wall of the sleeve. At the same time, the spring is arranged on the inner wall of the sleeve, and the end of the spring is connected to the round rod. At the same time, the end of the round rod is connected to the connecting block 33, so that the connecting block 33 is supported by the spring so that it is always in a taut state.

[0057] Further, multiple sets of positioning plates 32 are rotatably mounted on the outer surface of the power member 31, and the multiple sets of positioning plates 32 are evenly distributed on the outer surface of the power member 31. A clamping block 34 corresponding to the positioning plate 32 is rotatably mounted on the outer surface of the connecting block 33, and the outer surface of the clamping block 34 is rotatably connected to the end of the positioning plate 32.

[0058] Specifically, the end of the clamp block 34 is provided with a component having an anti-slip function such as rubber. At the same time, the outer surface of the clamp block 34 is limited by the positioning plate 32, and the clamp block 34 is supported by the connecting block 33, thereby preventing the clamp block 34 from loosening when positioning the ball 382.

[0059] Further, a bottom plate 35 is provided at the end of the connection block 33, and a driving member 36 is provided at the end of the bottom plate 35. A turntable 37 is provided at the output end of the driving member 36, and a plurality of guide grooves 371 are provided at the end of the turntable 37, and the plurality of guide grooves 371 are evenly distributed at the end of the turntable 37.

[0060] Specifically, the driving member 36 is a device with power output such as a motor, and is connected to an external control device. When the driving member 36 is started, it synchronously drives the turntable 37 arranged at its output end to rotate, wherein a guide groove 371 is arranged at the end of the turntable 37, so that when the turntable 37 rotates, the push rod 38 is driven to move toward the middle or expand outward.

[0061] At the same time, the push rod 38 is limited by the limiting plate 381, so that when the push rod 38 moves, the limiting plate 381 rotates around the connection with the bottom plate 35, thereby ensuring the overall stability of the push rod 38.

[0062] Furthermore, a sphere 382 is provided at the upper end of the push rod 38, and the outer surface of the sphere 382 is in contact with the inner wall of the clamping block 34. A ring 391 is provided on the inner wall of the connecting tube 39, and the inner wall of the ring 391 is in contact with the outer surface of the sphere 382.

[0063] Specifically, the outer surface of the sphere 382 is provided with a sealing component such as rubber, and the sphere 382 fits against the inner wall of the ring 391, thereby isolating the oil barrel 1 from the outside. When the push rod 38 moves toward the middle, it pushes the sphere 382 to move, thereby separating the sphere 382 from the ring 391, making it easier to introduce the cooled hydraulic oil into the oil barrel 1.

[0064] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
