Description

[Technical field]

[0001] The present invention relates to the technical field of gearboxes for wind power generating units, and in particular to a highly efficient heat-dissipating cooling device for gearboxes for wind power generators and the gearboxes. [Background technology]

[0002] A wind turbine is a power equipment that converts wind energy into mechanical work, which drives a rotor to rotate, and finally supplies AC power. Gearboxes are an important mechanical component widely used in wind power generation units, and their main function is to transmit the power generated by the windmill under the action of wind to the generator, so that the generator can obtain a suitable speed. However, after the existing gearboxes for wind turbines are operated for a long time, the gears meshed inside the gearbox rotate, generating a large amount of heat energy.

[0003] Chinese patent publication CN215172141U proposes a cooling device for a gearbox of a wind power generator. The device includes a gearbox, a water cooling source, a condensate tank, a radiator, a condensate pipe and a return water pipe. The water cooling source is fixedly connected to the gearbox, the condensate tank is connected to the water cooling source through the condensate pipe, the radiator is connected to the water cooling source through the return water pipe, the radiator is connected to the condensate tank through the return water pipe, a water pump is provided on the condensate pipe, and a plurality of water cooling sources are provided. The device, which has a simple structure, can greatly improve the heat dissipation efficiency of the condensate for the gearbox, and can efficiently dissipate heat from the condensate, promote the circulation of the condensate, save energy and reduce emissions.

[0004] In the above device, the heat dissipation member is arranged in a mesh-like manner, so a large amount of dust accumulates inside the heat dissipation member during use, which reduces the heat dissipation effect and even destroys the heat dissipation member. Moreover, the above device is an integrated type, so it needs to be removed for maintenance and cleaning, which is very inconvenient. Therefore, the present invention proposes a highly efficient heat dissipation cooling device for a gearbox for a wind turbine generator to solve the above problems.

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understandable, we will now describe the present invention in detail and completely in combination with drawings and embodiments. The embodiments described herein are some of the embodiments of the present invention, but not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings of this specification may be combined in various different configurations. EXAMPLES

[0018] Example 1 As shown in Fig. 1, Fig. 1 is a schematic diagram of a high-efficiency heat dissipation cooling device for a gearbox for a wind power generator according to a first embodiment of the present invention. Specifically, the high-efficiency heat dissipation cooling device for a gearbox for a wind power generator includes a controller, a facility water tank 1, and a filtered water tank 2 located on one side of the facility water tank 1.

[0019] Among them, the facility water tank 1 has a water supply port 7, a drain port, and an internal heat dissipation member. The filtered water tank 2 is composed of a water supply chamber 201, a drain chamber 202, and a filtration section 203 provided between the water supply chamber 201 and the drain chamber 202.

[0020] As shown in Figures 3 and 4, a mounting plate 3 is provided inside the facility water tank 1, and a lateral through hole is provided in the mounting plate 3. A first connecting pipe 4 is slidably connected to the inside of the lateral through hole, and the front end of the first connecting pipe 4 penetrates the front end of the facility water tank 1 and extends to the outside of the facility water tank 1.

[0021] A heat dissipation fan 5 is provided at the front end of the filtered water tank 2, and is electrically connected to the controller and controlled by the controller to exchange heat with the condensed water in the filtered water tank 2 to lower the temperature of the internal condensed water. A first connecting seat 204 that fits with the front end of the first connecting pipe 4 and a second connecting seat 205 that fits with the front end of the second connecting pipe 9 are provided at the rear end of the filtered water tank 2. The first connecting seat 204 communicates with the water supply chamber 201 of the filtered water tank 2, the second connecting pipe 9 is located on one side of the first connecting pipe 4, the rear end of the second connecting pipe 9 communicates with the inside of the facility water tank 1, and the second connecting seat 205 communicates with the drain chamber 202 of the filtered water tank 2. In some implementations, according to the flow direction of the condensed water, the front end of the first connecting pipe 4 is the insertion head, the rear end of the first connecting seat 204 is the insertion seat, the front end of the second connecting pipe 9 is the insertion seat, and the rear end of the second connecting seat 205 is the insertion head, and a backflow prevention plate is provided on the inside of the insertion seat to prevent the backflow of condensed water, and a sealing ring is provided on the outer surface of the insertion head to enhance the sealing effect of the joint. A connecting plate 6 and a flexible tube are provided at the rear end of the first connecting pipe 4, one end of the flexible tube is connected to the rear end of the first connecting pipe 4, and the other end of the flexible tube is connected to the water supply port 7 of the facility water tank 1.

[0022] Furthermore, in order to allow the connecting plate 6 to quickly return to its original position, the first connecting pipe 4 located between the front end of the connecting plate 6 and the rear end of the mounting plate 3 enters the spring 8. The first connecting pipe 4 is provided with an electromagnetic valve to control the flow of condensed water in the pipe. The filtered water tank 2 is provided with a tension bolt 10 penetrating both front and rear ends thereof, the front end of the connecting plate 6 is provided with a tension female thread tube 11 corresponding to the tension bolt 10, and the front end of the facility water tank 1 is provided with a through hole corresponding to the front end of the tension female thread tube 11, and the rear end of the tension bolt 10 fits the thread of the tension female thread tube 11. When the tension bolt 10 is twisted during use, the connecting plate 6 can move forward in conjunction with the tension bolt 10. The connecting plate 6 drives the first connecting pipe 4 to move forward, and compresses the spring 8 during the movement until the first connecting pipe 4 and the first connecting seat 204 are butted against each other. Furthermore, a non-contact proximity switch assembly is provided between the mounting plate 3 and the connection plate 6, and the non-contact proximity switch assembly is connected to the controller, and the controller is connected to the solenoid valve. By disposing the non-contact proximity switch assembly between the mounting plate 3 and the connection plate 6, the connection state between the filtered water tank 2 and the facility water tank 1 can be instantly obtained. When the filtered water tank 2 needs to be removed, the tension bolt 10 needs to be twisted, and then the mounting plate 3 and the connection plate 6 are separated by the reaction force of the spring 8. In this way, when the response of the non-contact proximity switch assembly is cut off, the connection information between the first connection pipe 4 and the first connection seat 204 can be accurately obtained so as to prevent the overflow of condensed water when the filtered water tank 2 is subsequently removed. The installation of the filtered water tank 2 is the same as above, and after the installation of the filtered water tank 2 is completed, the first connection pipe 4 communicates with the first connection seat 204 through the solenoid valve. The details thereof will not be repeated here again.

[0023] Specifically, in this embodiment, the non-contact proximity switch assembly includes a contact seat 12 provided at the rear end of the mounting plate 3 and a magnet member 13 provided at the front end of the connecting plate 6, and the contact seat 12 is connected to the controller. As shown in Fig. 2, two first connecting pipes 4 are arranged, and the two first connecting pipes 4 are respectively provided on both sides of the connecting plate 6. The tension female thread tube 11 is provided in the middle of the front end of the connecting plate 6.

[0024] In order to further enhance the stability of the connection between the filtered water tank 2 and the facility water tank 1, in this embodiment, connecting blocks 14 are provided on both sides of the exterior of the facility water tank 1, and fixing blocks 15 corresponding to the connecting blocks 14 are provided on both sides of the exterior of the filtered water tank 2, and both the connecting blocks 14 and the fixing blocks 15 are provided with horizontal screw holes.

[0025] Working principle: When the filtered water tank 2 needs to be removed, the screw connection between the connecting mass 14 and the fixed mass 15 is released, and then the tension bolt 10 is twisted in the reverse direction, and the connecting plate 6 moves to the rear end in cooperation with the tension bolt 10, moving the first connecting pipe 4 and the second connecting pipe 9 backward. At this time, the magnet member 13 leaves the contact seat 12 to start the controller, and the solenoid valve closes under the control of the controller, so that the condensed water does not overflow from the filtered water tank 2 under the action of the backflow prevention plate inside the insertion seat of the first connecting seat 204 and the backflow prevention plate of the insertion seat of the second connecting pipe 9. When the filtered water tank 2 needs to be installed, the filtered water tank 2 and the facility water tank 1 are butted together and the tension bolt 10 is twisted, and the connecting plate 6 moves to the front end in cooperation with the tension bolt 10, moving the first connecting pipe 4 and the second connecting pipe 9 forward. At this time, the magnet member 13 reacts to and connects with the contact seat 12 to start the controller, and when the solenoid valve opens under the control of the controller, the condensed water flows and filtering begins.

[0026] In summary, the highly efficient heat-dissipating cooling device for a gearbox for a wind turbine generator and the technical solution of the gearbox according to the present invention have at least the following advantages and beneficial effects:

[0027] In this invention, the removable filtered water tank 2 effectively solves the problem of impurity accumulation in the facility water tank 1 and ensures the heat dissipation effect of the facility water tank 1, and the non-contact proximity switch controls the flow of condensed water, making it easy to remove the filtered water tank 2 and facilitating subsequent maintenance and cleaning work.
