Description

Technical Field

[0001] The invention relates to the technical field of power generation equipment, in particular to a wind turbine housing with a self-cleaning function. Background Art

[0002] A generator is a device that converts mechanical energy into electrical energy. When running, the generator generates a lot of heat. If the heat cannot be dissipated in time, the heat will accumulate inside the generator, causing it to overheat, triggering the shutdown protection mechanism or directly damaging the generator. For this reason, the generator needs to be cooled.

[0003] A common way to dissipate heat from a generator is to set cooling fins on the generator casing, and use the cooling fins to increase the contact area between the generator casing and the air, so as to dissipate the heat inside the generator more quickly. However, cooling fins that are exposed to the outside for a long time are prone to dust accumulation, resulting in reduced heat dissipation efficiency. Therefore, it is necessary to regularly clean the dust on the surface of the generator. Most existing cleaning methods use manual or mechanical methods to clean the dust on the surface of the generator by wiping. However, for some generators with painted surfaces, such as wind turbines installed on the seashore, their surfaces are mostly covered with a special anti-rust paint layer. While wiping off the dust, the existing cleaning methods are also likely to damage the anti-rust paint layer on the surface of the wind turbine. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a wind turbine housing with a self-cleaning function, which is not likely to damage the anti-rust paint layer on the surface of the wind turbine when cleaning dust.

[0005] The present invention adopts the following technical solutions.

[0006] A wind turbine housing with a self-cleaning function, comprising a mounting seat for arranging a generator body, wherein the outer wall of the generator body is uniformly provided with a plurality of heat dissipation grooves along the circumferential direction, and the mounting seat is provided with a plurality of movable side plates arranged in sequence along the circumferential direction of the generator body, wherein the movable side plates are connected with a linkage mechanism, and the linkage mechanism can control the movement of the movable side plates so that the plurality of movable side plates are gathered into a wind collecting tube or the plurality of movable side plates are spread out into a scattering shape;

[0007] When the multiple moving side plates are gathered into a wind collecting tube, a heat dissipation channel is formed between the generator body and the wind collecting tube;

[0008] A fan is provided at one end of the generator body, and the fan can drive air to flow through the heat dissipation channel;

[0009] It also includes a glue injection mechanism and a rolling and kneading mechanism. The glue injection mechanism can inject cleaning glue into the heat dissipation channel, and the rolling and kneading mechanism can drive the cleaning glue in the heat dissipation channel to roll along the circumferential direction of the generator body.

[0010] Further, the linkage mechanism includes an active gear ring rotatably connected to the mounting seat, and a power assembly transmission-connected to the active gear ring;

[0011] The moving side plate is provided with a receiving rod extending along the axial direction of the generator body, the receiving rod is rotatably connected with the mounting seat, and the receiving rod is provided with a driven gear meshing with the driving gear ring.

[0012] Furthermore, the power assembly includes a first electric push rod and a transmission arm, wherein the first end of the transmission arm is hinged to the output end of the first electric push rod, and the second end of the transmission arm is hinged to the active gear ring.

[0013] Furthermore, a plurality of the glue injection mechanisms are evenly distributed along the axial direction of the generator body.

[0014] Furthermore, the glue injection mechanism includes a base, a storage cavity is formed in the base, a glue storage bottle is placed in the storage cavity, one end of the storage cavity close to the heat dissipation channel is connected to the glue injection channel, the end of the storage cavity facing away from the heat dissipation channel is slidably connected to an extrusion piston, and the extrusion piston is transmission-connected to a second electric push rod.

[0015] Furthermore, the glue injection channel is provided with a glue cutting component for cutting off the cleaning glue in the glue injection channel.

[0016] Furthermore, the rubber cutting assembly includes a rubber cutting knife and an electromagnet transmission-connected to the rubber cutting knife.

[0018] The beneficial effects of the present invention are:

[0019] The present invention is provided with a glue injection mechanism and a rolling and kneading mechanism. When it is necessary to clean the dust on the outer wall of the generator body, a plurality of movable side plates are gathered into an air collecting tube. At this time, the glue injection mechanism injects cleaning glue into the heat dissipation channel between the generator body and the air collecting tube. Then, the rolling and kneading mechanism drives the cleaning glue in the heat dissipation channel to roll along the circumferential direction of the generator body. In this process, the cleaning glue will adhere to and remove the dust on the outer wall of the generator body. Among them, since the cleaning glue is soft, it will not generate hard friction when it contacts the outer wall of the generator body, and its working principle is to rely on viscosity to remove dust, rather than through abrasion and scraping. Therefore, in the process of cleaning dust, the present invention is not easy to damage the anti-rust paint layer on the outer wall of the generator body. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0037] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present invention is further described below in conjunction with the drawings and embodiments.

[0038] As shown in the accompanying drawings, a wind turbine housing with a self-cleaning function includes a mounting base 2 for arranging a generator body 1, the outer wall of the generator body 1 is evenly distributed with a plurality of heat dissipation grooves 11 along the circumferential direction, and the mounting base 2 is provided with a plurality of movable side plates 31 arranged in sequence along the circumferential direction of the generator body 1, and the movable side plates 31 are connected to a linkage mechanism 4, and the linkage mechanism 4 can control the movement of the movable side plates 31, so that the plurality of movable side plates 31 are gathered into a wind collecting tube 3 or the plurality of movable side plates 31 are spread out into a scattered shape;

[0039] When the multiple moving side plates 31 are gathered together to form the wind collecting tube 3, a heat dissipation channel 3a is formed between the generator body 1 and the wind collecting tube 3;

[0040] A fan 5 is provided at one end of the generator body 1, and the fan 5 can drive air to flow through the heat dissipation channel 3a;

[0041] The device also includes a glue injection mechanism 6 and a rolling mechanism 7 . The glue injection mechanism 6 can inject cleaning glue into the heat dissipation channel 3 a , and the rolling mechanism 7 can drive the cleaning glue in the heat dissipation channel 3 a to roll along the circumferential direction of the generator body 1 .

[0042] Specifically, the housing of this embodiment has a passive heat dissipation mode, an active heat dissipation mode and a dust cleaning mode.

[0043] In the passive heat dissipation mode, the plurality of moving side plates 31 are spread out in a scattered shape, the fan 5 does not work at this time, and the generator body 1 dissipates heat by natural convection. It can be understood that the passive heat dissipation mode is suitable for the case where the heat generated by the generator body 1 is relatively small.

[0044] In the active heat dissipation mode, the plurality of movable side plates 31 are gathered into an air collecting tube 3, and a heat dissipation channel 3a is formed between the generator body 1 and the air collecting tube 3. At this time, the fan 5 works to drive air to flow through the heat dissipation channel 3a, thereby taking away the heat on the generator body 1 and cooling the generator body 1. It can be understood that the active heat dissipation mode is suitable for the case where the generator body 1 generates a large amount of heat.

[0045] In actual use, the housing of this embodiment can be switched between the passive heat dissipation mode and the active heat dissipation mode by manual or automatic program control, thereby reducing the energy consumption of heat dissipation while meeting the heat dissipation requirements of the generator body 1, which is beneficial to energy saving and environmental protection.

[0046] In the dust cleaning mode, the plurality of movable side plates 31 are gathered into the air collecting tube 3. At this time, the glue injection mechanism 6 injects the cleaning glue into the heat dissipation channel 3a. Then, the rolling and kneading mechanism 7 drives the cleaning glue in the heat dissipation channel 3a to roll along the circumferential direction of the generator body 1, so that the cleaning glue adheres to and removes the dust on the outer wall of the generator body 1. In this process, since the cleaning glue is soft, it will not produce hard friction when it contacts the outer wall of the generator body 1, and its working principle is to rely on viscosity to remove dust, rather than through abrasion and scraping, so it is not easy to damage the anti-rust paint layer on the outer wall of the generator body 1.

[0047] Preferably, the linkage mechanism 4 includes an active gear ring 41 rotatably connected to the mounting seat 2, and a power assembly transmission-connected to the active gear ring 41; a receiving rod 311 extending along the axial direction of the generator body 1 is provided on the moving side plate 31, the receiving rod 311 is rotationally connected to the mounting seat 2, and a driven gear 312 meshing with the active gear ring 41 is provided on the receiving rod 311. The power assembly includes a first electric push rod 42 and a transmission arm 43, a first end of the transmission arm 43 is hinged to the output end of the first electric push rod 42, and a second end of the transmission arm 43 is hinged to the active gear ring 41.

[0048] Specifically, the driven gear 312 is inscribed in the driving gear ring 41. When the first electric push rod 42 is extended, the driving gear ring 41 will rotate in the clockwise direction, thereby driving the driven gear 312 to rotate in the clockwise direction, thereby expanding the moving side plate 31 into a scattered shape.

[0049] On the contrary, when the first electric push rod 42 is shortened, the driving gear ring 41 will rotate in the counterclockwise direction, thereby driving the driven gear 312 to rotate in the counterclockwise direction, thereby causing the moving side plate 31 to be folded into the air collecting cylinder 3.

[0050] Preferably, multiple glue injection mechanisms are evenly distributed along the axial direction of the generator body 1. In the dust cleaning mode, multiple glue injection mechanisms simultaneously inject cleaning glue into the heat dissipation channel 3a, so that the cleaning glue is evenly distributed along the long direction of the heat dissipation channel 3a. In this way, when the rolling and kneading mechanism 7 drives the cleaning glue to roll along the circumferential direction of the generator body 1, the evenly distributed cleaning glue can clean the dust on the outer wall of the generator body 1 in all directions.

[0051] Preferably, the glue injection mechanism includes a base 61, a storage chamber 6a is formed in the base 61, a glue storage bottle 62 is placed in the storage chamber 6a, one end of the storage chamber 6a close to the heat dissipation channel 3a is connected to the glue injection channel 6b, and the end of the storage chamber 6a facing away from the heat dissipation channel 3a is slidably connected to an extrusion piston 63, and the extrusion piston 63 is transmission-connected to a second electric push rod 64.

[0052] Specifically, a fixed side plate 32 is provided on the mounting seat 2. When the plurality of movable side plates 31 are folded together, the movable side plates 31 and the fixed side plates 32 together form an air collecting tube 3. The glue injection mechanism is provided on the fixed side plate 32. When it is necessary to inject the cleaning glue in the glue storage bottle 62 into the heat dissipation channel 3a, the second electric push rod 64 will drive the extrusion piston 63 to compress the glue storage bottle 62, so that the cleaning glue in the glue storage bottle 62 flows into the heat dissipation channel 3a through the glue injection channel 6b. It can be understood that by adjusting the extension and contraction amount of the second electric push rod 64, the amount of cleaning glue flowing into the heat dissipation channel 3a can be accurately controlled.

[0053] Preferably, in order to avoid the cleaning glue in the heat dissipation channel 3a from adhering to the cleaning glue in the glue storage bottle 62, the glue injection channel 6b is provided with a glue cutting assembly for cutting off the cleaning glue in the glue injection channel 6b. The glue cutting assembly includes a glue cutting knife 65, and an electromagnet 66 connected to the glue cutting knife 65. In the process that the cleaning glue flows into the heat dissipation channel 3a through the glue injection channel 6b, the electromagnet 66 saves the contraction state, so that the glue cutting knife 65 withdraws from the glue injection channel 6b, and the flow of the cleaning glue is not hindered. After a predetermined amount of cleaning glue flows into the heat dissipation channel 3a, the electromagnet 66 is converted from the contraction state to the extension state, prompting the glue cutting knife 65 to extend into the glue injection channel 6b, thereby cutting off the cleaning glue in the glue injection channel 6b.

[0054] Preferably, the rolling and kneading mechanism 7 includes a driven gear ring 71 rotatably connected to the mounting seat 2, a driving gear 72 meshing with the driven gear ring 71, and a motor 73 drivingly connected to the driving gear 72, and a plurality of rolling and kneading rods 74 extending along the axial direction of the generator body 1 are evenly distributed on the driven gear ring 71. It can be understood that after the motor 73 is started, the driving gear 72 drives the driven gear ring 71 to rotate, so that the rolling and kneading rods 74 on the driven gear ring 71 make a circular motion along the circumference of the heat dissipation channel 3a, so that the cleaning glue in the heat dissipation channel 3a rolls closely against the outer wall of the generator body 1, and then the cleaning glue absorbs the dust on the outer wall of the generator body 1.

[0055] It is understandable that during the rolling process of the cleaning glue, its surface will gradually become covered with dust, and the dust will form an isolation layer on the surface of the cleaning glue, hindering the contact between the cleaning glue and the remaining dust, which is not conducive to fully cleaning the dust on the outer wall of the generator body 1. To solve this problem, in this embodiment, when the rolling and kneading rod 74 drives the cleaning glue to roll, the heat dissipation groove 11 on the generator body 1 will cooperate with the rolling and kneading rod 74 to knead the cleaning glue, thereby mixing the sticky substance inside the cleaning glue with the dust on the surface, and then forming a new sticky layer on the surface of the cleaning glue. This new sticky layer can better absorb the remaining dust, which helps to fully clean the outer wall of the generator body 1.

[0056] After cleaning is completed, the plurality of movable side plates 31 are spread out in a scattered shape, and the rolling and kneading mechanism 7 continues to drive the cleaning glue on the outer wall of the generator body 1 to roll in the circumferential direction. When the cleaning glue rolls to the lower half of the generator body 1, the cleaning glue will naturally fall off from the generator body 1 under the action of gravity because the air collecting tube 3 is no longer limited.

[0057] It is understandable that, since the cleaning glue needs to be stored in a cool environment, the temperature of the cleaning glue just injected into the heat dissipation channel 3a is lower than that of the generator body 1. In the process of the cleaning glue rolling against the outer wall of the generator body 1, it will gradually absorb the heat from the generator body 1, which not only helps the auxiliary heat dissipation of the generator body 1, but also makes it easier for the subsequent cleaning glue to fall off naturally from the generator body 1 as its own temperature rises.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
