Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbines, and particularly relates to a non-porous end cover of a wind turbine with a heat dissipation structure. Background Technique

[0002] A wind turbine is a power device that converts wind energy into mechanical work. The mechanical work drives the rotor to rotate, and finally outputs alternating current. The rear end cover of the wind turbine is installed at the end of the wind turbine and is used to fix and protect the power transmission system in the fan. The end cover protects the bearing and other key components from the erosion of wind and other harsh environments.

[0003] At present, due to the need to consider factors such as humid air, strong wind and large dust in the high altitude, the rear end cover of the wind turbine generally does not have heat dissipation holes to ensure the safety of the tail end system of the wind turbine. This results in poor heat dissipation performance of the sealed rear end cover covering the tail end area of the wind turbine. The power transmission system part of the generator is prone to use failures and a decrease in service life due to long-term heat accumulation. In addition, the traditional rear end cover of the wind turbine is a single-layer structure and fits on the tail seat of the generator. After being bumped and deformed, this kind of generator rear end cover is easy to squeeze the power transmission system it protects.

[0004] Therefore, there is a need for a non-porous end cover of a wind turbine with a heat dissipation structure to solve the problems that the sealed rear end cover in the prior art has poor heat dissipation performance when covering the tail end area of the wind turbine and the single-layer structure of the end cover has a general anti-collision effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a non-porous end cover of a wind turbine with a heat dissipation structure to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A non-porous end cover of a wind turbine with a heat dissipation structure, including a rear end cover body. An assembly port is opened on the tail end surface of the rear end cover body. A non-porous heat dissipation structure is arranged at the tail end of the rear end cover body. The non-porous heat dissipation structure includes a heat conduction circular plate, a heat conduction straight pipe and a water storage cooling box. The heat conduction circular plate is embedded and fixed in the assembly port of the rear end cover body. The heat conduction straight pipe is fixed on one end surface of the heat conduction circular plate. The water storage cooling box is fixed at the end of the heat conduction straight pipe away from the heat conduction circular plate. A protective cover shell is sleeved and fixed outside the rear end cover body.

[0007] It should be noted in the solution that a hollow cavity is arranged between the protective cover shell and the rear end cover body, and a dust-proof ventilation port is opened on the side surface of the protective cover shell.

[0008] It is further worth mentioning that the dustproof ventilation port of the protective cover shell is communicated with the hollow chamber, and the rear end cover body is sleeved on the tail seat of the wind turbine.

[0009] It should be further explained that the heat-conducting circular plate is attached to the tail end of the wind turbine, and one end of the heat-conducting straight pipe extends out of the protective cover.

[0010] As a preferred embodiment, a circular hole for passing a pipe is opened on the rear end surface of the protective cover shell, and the heat-conducting straight pipe matches the circular hole for passing a pipe of the protective cover shell.

[0011] As a preferred embodiment, a water inlet port is provided on the upper portion of the water storage cooling box, and the water inlet port is communicated with the water storage chamber of the water storage cooling box.

[0012] As a preferred embodiment, a water injection lumen is provided inside the heat-conducting straight pipe, a connecting hole is provided on the inner wall of the water storage cooling box, and the water injection lumen of the heat-conducting straight pipe is connected to the connecting hole of the water storage cooling box.

[0013] As a preferred embodiment, the side surfaces of the protective cover shell and the rear end cover body are both provided with mounting holes, and the mounting holes are aligned with the positions of the preset screw holes on the tail seat of the wind turbine.

[0014] Compared with the prior art, the utility model provides a non-hole-type wind turbine end cover with a heat dissipation structure, which has at least the following beneficial effects:

[0015] ⑴ Through the setting of the hole-free heat dissipation structure, the heat inside the rear end cover is discharged to the outside through the heat-conducting circular plate and the heat-conducting straight pipe to achieve the purpose of efficient heat dissipation. At the same time, the heat-conducting straight pipe is connected to the water storage cooling box. In this way, when there is water inside the water storage cooling box and it is poured into the heat-conducting straight pipe to enhance the heat dissipation performance, the water storage cooling box can store water in the rainy season. This method can make full use of rainwater resources for subsequent cooling use.

[0016] ⑵ By setting up the protective cover shell, rear end cover body, hollow chamber and dustproof vent, during use, the double-layer protective shell formed by the protective cover shell and the rear end cover body can enhance the protection effect on the tail end of the wind turbine, and the hollow chamber formed between the protective cover shell and the rear end cover body can provide a recessed space for the deformation of the protective cover shell and reduce the trouble of squeezing the tail end of the wind turbine. The hollow chamber is connected to the outside world through the dustproof vent, so that the outside air flow is poured into the dustproof vent and circulated inside the hollow chamber, which can also promote the dissipation of heat on the surface of the rear end cover body.

Specific embodiments

[0023] The following further describes the present invention in combination with embodiments.

[0024] Please refer to Figures 1-4 , the present invention provides an end cover of a holeless wind turbine with a heat dissipation structure, including a rear end cover body 2. An assembly port 12 is opened on the end face of the rear end cover body 2. A holeless heat dissipation structure is provided at the end of the rear end cover body 2. The holeless heat dissipation structure includes a heat-conducting circular plate 6, a heat-conducting straight pipe 7, and a water storage cooling box 8. The heat-conducting circular plate 6 is embedded and fixed in the assembly port 12 of the rear end cover body 2. The heat-conducting straight pipe 7 is fixed on one end face of the heat-conducting circular plate 6. The water storage cooling box 8 is fixed at the end of the heat-conducting straight pipe 7 away from the heat-conducting circular plate 6. A protective cover shell 1 is sleeved and fixed outside the rear end cover body 2.

[0025] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3As shown, it is worth mentioning that a hollow chamber 3 is provided between the protective cover shell 1 and the rear end cover body 2, and a dustproof vent 4 is provided on the side surface of the protective cover shell 1. During use, the double-layer protective shell formed by the protective cover shell 1 and the rear end cover body 2 can enhance the protection effect on the tail end of the wind turbine, and the hollow chamber 3 formed between the protective cover shell 1 and the rear end cover body 2 can provide a recessed space for the deformation of the protective cover shell 1 and reduce the trouble of squeezing the tail end of the wind turbine. In addition, the hollow chamber 3 is connected to the outside world through the dustproof vent 4, so that when the external wind flow is poured into the dustproof vent 4 and circulates inside the hollow chamber 3, it can also promote the dissipation of heat on the surface of the rear end cover body 2.

[0026] Further as Figure 3 As shown, it is worth noting that the dustproof vent 4 of the protective cover shell 1 is connected to the hollow chamber 3, and the rear end cover body 2 is sleeved on the tail seat of the wind turbine.

[0027] This solution has the following working process: before use, the rear end cover body 2 is fixed to the tail seat of the wind turbine by bolts and mounting holes 5. During use, the heat inside the rear end cover body 2 is transferred to the heat-conducting straight pipe 7 through the heat-conducting circular plate 6, and the heat-conducting straight pipe 7 extends out of the protective cover shell 1 after passing through the hollow chamber 3. In this way, the heat inside the rear end cover body 2 is discharged to the outside through the heat-conducting circular plate 6 and the heat-conducting straight pipe 7 to achieve the purpose of efficient heat dissipation. At the same time, the heat-conducting straight pipe 7 is connected to the water storage cooling box 8. In this way, when there is water inside the water storage cooling box 8 and it is poured into the heat-conducting straight pipe 7 to enhance the heat dissipation performance, the water storage cooling box 8 can store water in the rainy season. This method can make full use of rainwater resources for subsequent cooling use.

[0028] According to the above working process, it can be seen that the heat inside the rear end cover body 2 is discharged to the outside through the heat-conducting circular plate 6 and the heat-conducting straight pipe 7 to achieve the purpose of efficient heat dissipation. At the same time, the heat-conducting straight pipe 7 is connected to the water storage cooling box 8. In this way, when there is water inside the water storage cooling box 8 and it is poured into the heat-conducting straight pipe 7 to enhance the heat dissipation performance, the water storage cooling box 8 can store water in the rainy season. This method can make full use of rainwater resources for subsequent cooling use.

[0029] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the heat-conducting circular plate 6 is attached to the tail end of the wind turbine, and one end of the heat-conducting straight pipe 7 extends out of the protective cover 1.

[0030] Further as Figure 4 As shown, it is worth mentioning that a circular hole 13 for passing a pipe is opened on the rear end surface of the protective cover shell 1 , and the heat-conducting straight pipe 7 matches the circular hole 13 for passing a pipe of the protective cover shell 1 .

[0031] Further as Figure 1As shown, it is worth noting that a water inlet port 11 is provided on the upper portion of the water storage cooling box 8 , and the water inlet port 11 is communicated with the water storage chamber of the water storage cooling box 8 .

[0032] Further as Figure 1 As shown, it is worth mentioning that a water injection lumen 9 is provided inside the heat-conducting straight pipe 7, and a connecting hole 10 is provided on the inner wall of the water storage cooling box 8. The water injection lumen 9 of the heat-conducting straight pipe 7 is connected to the connecting hole 10 of the water storage cooling box 8.

[0033] Further as Figure 1 As shown, it is worth noting that the side surfaces of the protective cover shell 1 and the rear end cover body 2 are both provided with mounting holes 5, and the mounting holes 5 are aligned with the positions of the preset screw holes on the tail seat of the wind turbine.

[0034] In summary: the heat inside the rear end cover body 2 is conducted to the outside through the heat-conducting circular plate 6 and the heat-conducting straight pipe 7 to achieve the purpose of efficient heat dissipation. At the same time, the heat-conducting straight pipe 7 is connected to the water storage cooling box 8. In this way, when there is water inside the water storage cooling box 8 and it is poured into the heat-conducting straight pipe 7 to enhance the heat dissipation performance, the water storage cooling box 8 can store water in the rainy season. This method can make full use of rainwater resources for subsequent cooling use; during use, the double-layer protective shell formed by the protective cover shell 1 and the rear end cover body 2 can enhance the protection effect on the tail end of the wind turbine, and the hollow chamber 3 formed between the protective cover shell 1 and the rear end cover body 2 can provide a recessed space for the deformation of the protective cover shell 1 and reduce the trouble of squeezing the tail end of the wind turbine. The hollow chamber 3 is connected to the outside through the dustproof vent 4, so when the external airflow is poured into the dustproof vent 4 and circulated inside the hollow chamber 3, it can also promote the dissipation of heat on the surface of the rear end cover body 2.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
