[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limiting safety mechanism and an energy storage device. During the operation of a wind turbine, high temperature will be generated inside, and a cooling and heat dissipation device is required.

[0003] At present, the cooling devices for wind power generation on the market have poor heat dissipation effect. When people are using wind turbines, they cannot cool down the inside in time, which easily causes high-temperature burnout of internal components and is inconvenient for people to use. In related technologies, cooling is performed by setting fans, air inlets and outlets, and filters. However, in actual use, after long-term use of the filter, a lot of dust will remain on the surface, affecting the air flow and reducing the heat dissipation efficiency. Generally, it is necessary to disassemble and clean it. However, during the cleaning process, the dust can directly enter the wind power equipment and reduce the service life of the generator set, which has certain limitations. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] The wind acts on the impeller, causing it to rotate. The rotation of the impeller is transmitted to the generator, which in turn drives the rotor inside the generator to rotate. During the rotation of the rotor, the rotor inside the generator converts mechanical energy into electrical energy through the principle of electromagnetic induction. During this conversion process, the coil inside the generator will generate current due to changes in the magnetic field. The fan is then turned on to draw out the air in the cabin. At the same time, external air enters the cabin, allowing the fan to dissipate heat inside the cabin.

[0030] In the related art, after the cabin has been subjected to heat dissipation treatment, when the filter needs to be cleaned, the screws on the filter are directly unscrewed, and the filter is then disassembled and cleaned. However, in actual use, after the filter is removed, the air inside the cabin circulates with the outside, causing dust to directly enter the cabin, reducing the service life of the device.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a heat dissipation device. When the filter needs to be cleaned, it is only necessary to pull the limit plate 25 outward, cancel the fixation of the filter 22, and directly remove the filter 22. The hole body 15 is covered by the plate body 23 to play a dust-proof role. It is more convenient and quick, and the convenience of the device is improved.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 3 , the embodiment of the present application provides a heat dissipation device, including a main body component 1; the main body component 1 includes: a support frame 11, on which a generator compartment 12 is arranged; an impeller 13, arranged on the generator compartment 12; a fan 14, arranged on the generator compartment 12; a hole body 15, opened on the generator compartment 12; a disassembly component 2 is arranged on the generator compartment 12; the disassembly component 2 includes: a mounting seat 21, arranged on the generator compartment 12; a filter screen 22, arranged on the mounting seat 21; a plate body 23, slidably connected to the generator compartment 12; a rod body 24, arranged on the plate body 23, one end of the rod body 24 passes through the mounting seat 21; a limit plate 25, arranged at one end of the rod body 24, and the other end of the limit plate 25 is inserted into the mounting seat 21 and the filter screen 22 in sequence; a spring 26, sleeved on the outside of the rod body 24; a hole body 27, opened on the plate body 23.

[0034] When in use, after the wind contacts the impeller 13, it pushes the impeller 13 to rotate, and the rotation of the impeller 13 is transmitted to the generator, thereby driving the rotor inside the generator to rotate. During the rotation of the rotor, the rotor inside the generator converts mechanical energy into electrical energy through the principle of electromagnetic induction. During this conversion process, the coil inside the generator will generate current due to the change in the magnetic field, and then the fan 14 is turned on to draw the air in the generator compartment 12, and at the same time, the external air enters the generator compartment 12 through the hole 15, so that the fan 14 dissipates heat inside the generator compartment 12. When it is turned on to enter the generator compartment 12, the dust in the air is filtered through the filter 22. When the filter 22 needs to be removed, When unloading and cleaning, the limit plate 25 is directly pulled outward so that the limit plate 25 pulls the rod body 24 and the plate body 23 until one end of the limit plate 25 slides out of the filter screen 22, and then the filter screen 22 is directly pulled upward to realize the removal of the filter screen 22. Finally, the limit plate 25 is released, and the plate body 23 pulls the rod body 24 and the limit plate 25 through the rebound force of the spring 26. At this time, the hole body 15 and the hole body 27 are aligned, and the plate body 23 continues to slide until the limit plate 25 is tightly attached to the mounting seat 21, and the hole body 15 and the hole body 27 are not in contact, so that the plate body 23 covers and seals the generator compartment 12 to prevent dust from entering the generator compartment 12 during the cleaning process, and vice versa to realize the installation of the filter screen 22.

[0035] In some embodiments, a slide rail is provided on the generator compartment 12 to restrict the plate 23 to slide only horizontally.

[0036] In some embodiments, the limiting plate 25 is T-shaped, which makes it convenient for workers to pull the limiting plate 25.

[0037] In some embodiments, an auxiliary component 3 is provided on the rod body 24; the auxiliary component 3 includes: a limit block 31, which is provided on the outside of the rod body 24, one end of the rod body 24 passes through the limit plate 25 and is threadedly connected to the limit plate 25 through the limit block 31, and the other end of the rod body 24 is rotatably connected to the plate body 23; a thread 32, which is provided on the outer end of the rod body 24.

[0038] When in use, the rod body 24 is rotated so that the rod body 24 rotates on the plate body 23 , and at the same time, the thread 32 is connected with the thread of the limiting plate 25 so that the rod body 24 moves horizontally on the limiting plate 25 .

[0039] In some embodiments, the limit block 31 is higher than the generator compartment 12 , so that the staff can easily rotate the limit block 31 .

[0040] In some embodiments, the hole body 1 15 and the hole body 2 27 are both provided with a plurality of holes to improve heat dissipation efficiency.

[0041] In some embodiments, a buckle is provided on the filter 22 and a slot is provided on the mounting seat 21 to facilitate disassembly of the filter 22 .

[0042] In some embodiments, a through slot is formed on the mounting seat 21 , and the rod body 24 passes through the mounting seat 21 through the through slot. The diameter of the through slot is larger than the diameter of the rod body 24 , so as to prevent the mounting seat 21 from affecting the sliding of the rod body 24 .

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
