Description

Technical Field

[0001] This utility model belongs to the technical field of gearbox oil tanks, specifically relating to an automatic oil temperature compensation device for wind turbine gearboxes. Background Technology

[0002] A wind turbine generally refers to a wind power generator set, which is a system that converts the kinetic energy of wind into electrical energy. The gearbox is one of the most important and expensive components of a wind turbine. Its main function is to transmit the power generated by the wind turbine under wind conditions to the generator, enabling it to achieve the corresponding rotational speed. For large-scale projects like wind turbines, the gearbox is usually equipped with a dedicated oil tank. Oil is drawn from this tank and sprayed into designated areas inside the gearbox for lubrication. After being sprayed out, the lubricating oil flows back into the tank through specific return lines or pipes. This cycle continuously lubricates the gearbox. However, the temperature of the lubricating oil in the tank also has certain requirements. If the lubricating oil absorbs a large amount of heat from the gearbox, causing the oil temperature to be too high, it is necessary to dissipate the oil temperature. The common method is to install heat dissipation holes and a cooling fan on the oil tank to lower the oil temperature. When the oil temperature is too low, it is necessary to heat the oil appropriately. The existing oil tank is not convenient to flexibly meet the different needs in these two situations, and heat dissipation and heating are also prone to mutual interference, which is not conducive to the normal use of the gearbox. Therefore, a new automatic oil temperature compensation device needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide an automatic oil temperature compensation device for wind turbine gearboxes, in order to solve the problems mentioned in the background art, such as the fact that the oil tank of the existing gearbox is not convenient to flexibly meet the needs of heat dissipation and heating under different conditions, and that heat dissipation and heating are prone to mutual influence and interference.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic oil temperature compensation device for wind turbine gearboxes, comprising...

[0005] The oil tank includes a rectangular box body, a bottom compartment at the bottom of the box body, and a resistance wire inside the bottom compartment.

[0006] The regulating assembly includes a top box fixed to the top of the housing, a solenoid valve installed inside the top box, and a connecting pipe connected to the bottom of the solenoid valve and extending into the housing.

[0007] A curved heat dissipation copper pipe is installed on the top of the enclosure. One end of the curved heat dissipation copper pipe extends into the top box and is connected to one end of the solenoid valve, while the other end extends into the interior of the enclosure.

[0008] Preferably, an oil inlet pipe is connected to one side of the top box, and the oil inlet pipe is connected to the other end of the solenoid valve. An oil outlet pipe is connected to one side of the bottom of the box.

[0009] Preferably, the adjustment assembly further includes a top cover, which is rotatably connected to the top of the top box.

[0010] Preferably, a blower assembly is provided on the top surface of the oil tank directly below the curved heat dissipation copper pipe, and the blower assembly includes an exhaust fan fixedly installed on the top surface of the oil tank.

[0011] Preferably, the blower assembly further includes support bars, which are fixedly supported at the bottom of both ends of the exhaust fan.

[0012] Preferably, the oil tank is equipped with a thermometer, the bottom of which extends into the interior of the tank.

[0013] Preferably, the solenoid valve, thermometer, exhaust fan, and resistance wire are all connected with wires, and the solenoid valve, thermometer, exhaust fan, and resistance wire are connected in a circuit through the wires.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The designed curved heat dissipation copper pipe and resistance wire can separately dissipate heat and heat the oil, achieving automatic oil temperature compensation. By adjusting the components, when heat dissipation is needed, the oil can pass through the curved heat dissipation copper pipe, and when heating is needed, the oil will not pass through the curved heat dissipation copper pipe. This design allows the oil tank to dissipate heat and heat the oil in two different locations, which is not only flexible and convenient, but also prevents mutual interference, thus promoting the normal lubrication effect of the gearbox.

[0023] The oil tank 100 includes a rectangular box body 101, a bottom interlayer 102 disposed at the bottom of the box body 101, and a resistance wire 103 disposed inside the bottom interlayer 102. If the oil inside the box body 101 needs to be heated, the resistance wire 103 can be turned on to raise the oil temperature.

[0024] The regulating component 200 includes a top box 201 fixed to the top of the housing 101, a solenoid valve 202 installed inside the top box 201, and a connecting pipe 203 connected to the bottom end of the solenoid valve 202 and extending into the housing 101; a curved heat dissipation copper pipe 500 is disposed on the top of the housing 101, one end of which extends into the top box 201 and is connected to one end of the solenoid valve 202, and the other end extends into the housing 101. The solenoid valve 202 can adjust the temperature. Regarding the flow of lubricating oil, when heat dissipation is required, the lubricating oil can flow into the curved heat dissipation copper pipe 500, where it will dissipate heat before flowing into the housing 101. If the lubricating oil does not require heat dissipation or heating, the solenoid valve 202 can be used to directly introduce the lubricating oil into the housing 101 through the connecting pipe 203. If heating is required, the resistance wire 103 can be turned on to heat the lubricating oil, provided that the lubricating oil flows from the connecting pipe 203 into the housing 101.

[0025] In this embodiment, preferably, an oil inlet pipe 300 is connected to one side of the top box 201, and the other end of the oil inlet pipe 300 is connected to the solenoid valve 202. An oil outlet pipe 400 is connected to one side of the bottom of the housing 101. The oil inlet pipe 300 and the oil outlet pipe 400 can be connected to an external pump body. The lubricating oil inside the gearbox is drawn out through the oil inlet pipe 300 and allowed to flow back into the housing 101. The lubricating oil inside the housing 101 is drawn out through the oil outlet pipe 400 and introduced into the gearbox for lubrication.

[0026] In this embodiment, preferably, the adjustment component 200 further includes a top cover 204, which is rotatably connected to the top of the top box 201. The top cover 204 can be opened to allow for the inspection and maintenance of the solenoid valve 202.

[0027] In this embodiment, preferably, a blower assembly 600 is provided on the top surface of the oil tank 100 directly below the curved heat dissipation copper pipe 500. The blower assembly 600 includes an exhaust fan 601 fixedly installed on the top surface of the oil tank 100. When the oil temperature is too high, the exhaust fan 601 can be activated to blow air onto the curved heat dissipation copper pipe 500 from bottom to top, thereby improving the heat dissipation performance.

[0028] In this embodiment, preferably, the blower assembly 600 further includes a support bar 602, which is fixedly supported at the bottom of both ends of the exhaust fan 601, allowing the exhaust fan 601 to be suspended in the air, thereby forming an air duct that grows from below.

[0029] In this embodiment, preferably, a thermometer 700 is provided on the oil tank 100, and the bottom end of the thermometer 700 extends into the interior of the tank body 101 to detect the oil temperature inside the oil tank 100.

[0030] In this embodiment, preferably, the solenoid valve 202, thermometer 700, exhaust fan 601, and resistance wire 103 are all connected to wires 800. These four components are electrically connected via wires 800. The wires 800 on the solenoid valve 202, thermometer 700, exhaust fan 601, and resistance wire 103 can be centrally connected to a programmable logic controller (PLC). Users can preset three temperature nodes, such as temperatures A, B, and C from low to high. When the thermometer 700 detects that the oil temperature is lower than temperature A, the PLC controls... Solenoid valve 202 allows lubricating oil to enter the oil tank 100 directly through connecting pipe 203, and simultaneously activates resistance wire 103 to heat the lubricating oil. When the oil temperature is between temperature A and temperature B, the oil temperature is just right, and the lubricating oil can enter the oil tank 100 through connecting pipe 203. When the oil temperature is between temperature B and temperature C, the programmable logic controller controls solenoid valve 202 to allow the lubricating oil to pass through curved heat dissipation copper pipe 500 for heat dissipation. When the oil temperature exceeds temperature C, when the lubricating oil passes through curved heat dissipation copper pipe 500, exhaust fan 601 can be activated simultaneously for auxiliary heat dissipation to improve the heat dissipation effect.

[0031] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
