Description

Technical Field

[0001] The invention relates to the technical field of wind-assisted rotor heat dissipation, and in particular to a wind-assisted rotor ventilation and heat dissipation device. Background Art

[0002] Wind-assisted rotors are usually large in size and need to maintain a high rotation speed to work continuously in order to provide continuous propulsion for the ship's navigation. The outer cylinder and the inner tower are generally connected by bearings, and continuous friction will generate a large amount of heat. At the same time, wind-assisted rotors are usually driven by a motor located inside the tower body. In order to maintain stability, the motor is generally placed at a higher position, and the overall space is relatively closed and limited, resulting in a lot of heat often accumulating inside the tower body. High temperature will seriously affect the stability of the motor's operation, and thus affect the continuous operation of the rotor. The rotor heat dissipation device in the prior art usually does not have ventilation holes, or cannot effectively perform ventilation and heat dissipation work, or the heat dissipation solution is too complicated, which increases the production cost.

[0044] Embodiment 1

[0045] like Figure 1 As shown, this embodiment provides a wind-assisted rotor ventilation and heat dissipation device, which includes a cylinder 2, a top cover 3 and a rain shield 4. Specifically, as Figure 2 and Figure 3 As shown, the top cover 3 is set to cover the top of the cylinder 2, and a manhole 1 is opened on the top cover 3, and the manhole 1 is connected to the inner cavity of the cylinder 2. The rain shield 4 is set to cover the top of the manhole 1, and the rain shield 4 is spaced apart from the top cover 3 to form a heat dissipation gap connected to the external atmosphere. Figure 4 As shown, this embodiment provides a wind-assisted rotor ventilation and heat dissipation device so that the heat inside the cylinder 2 is dissipated to the outside atmosphere through the heat dissipation gap under the action of the exhaust fan 8. In rainy and snowy weather, the rain shield 4 can block rain and snow from entering the interior of the cylinder 2 to prevent the motor or other components in the cylinder 2 from being damaged by the rain and snow.

[0046] Specifically, a plurality of support columns 5 are used to support the rain shield 4 above the manhole 1, and the support columns 5 are detachably connected between the rain shield 4 and the top cover 3. Furthermore, a plurality of support columns 5 are arranged at intervals along the circumferential direction of the top cover 3. Under this structure, a plurality of support columns 5 divide the heat dissipation gap into a plurality of sub-gaps, and the heat inside the cylinder 2 is dissipated to the outside atmosphere through the sub-gaps between two adjacent support columns 5. Preferably, a plurality of support columns 5 are evenly distributed between the rain shield 4 and the top cover 3. On the one hand, such an arrangement can improve the connection stability between the rain shield 4 and the top cover 3, so that the rain shield 4 can be stably and horizontally arranged above the manhole 1. On the other hand, the plurality of support columns 5 are evenly distributed so that the sizes of the plurality of sub-gaps are the same, thereby making the heat dissipation effect more uniform. In this embodiment, the support column 5 is fastened between the rain shield 4 and the top cover 3 by bolts. On the one hand, when the internal parts of the cylinder 2 are damaged, the maintenance personnel can quickly disassemble the rain shield 4 and enter the cylinder 2 through the manhole 1 for maintenance; on the other hand, if the rain shield 4 is eroded or damaged, it is also convenient for the maintenance personnel to replace the rain shield 4 in time. Further, in order to ensure that the support column 5 can stably support the rain shield 4 and improve the connection stability between the rain shield 4 and the top cover 3, in this embodiment, the number of the support columns 5 is 16. In other embodiments, the number of the support columns 5 can also be designed according to actual conditions.

[0047] Specifically, the rain shield 4 includes a first rain shield 41 and a second rain shield 42. The first rain shield 41 is an annular plate, which is located directly above the manhole 1. In order to increase the rain protection area, the second rain shield 42 is configured as an annular inclined plate, one end of the second rain shield 42 is connected to the first rain shield 41 at a first preset angle, and the other end of the second rain shield 42 is inclined downward toward the top cover 3. Under this structure, a certain heat dissipation gap is still left between the second rain shield 42 and the top cover 3 to prevent the heat in the cylinder 2 from being unable to be dissipated to the external atmosphere in time. In order to increase the wind resistance of the rain shield 4, preferably, in this embodiment, the first rain shield 41 and the second rain shield 42 are integrally formed.

[0048] In order to prevent rainwater falling on the top cover 3 from flowing into the interior of the cylinder 2 through the manhole 1, a rain shielding boss 7 is provided on the inner circle of the top cover 3. Preferably, the rain shielding boss 7 is annular.

[0049] In order to extend the service life of the wind-assisted rotor ventilation and heat dissipation device in this embodiment, the surfaces of the top cover 3 and the rain shield 4 are coated with a sun-proof and waterproof layer.

[0050] Furthermore, an insect screen is provided between the rain shield 4 and the top cover 3 to prevent foreign objects such as insects from falling into the interior of the cylinder 2 .

[0051] The wind-assisted rotor ventilation and heat dissipation device provided in this embodiment covers the manhole 1 of the top cover 3 with a rain shield 4, and a heat dissipation gap connected to the outside atmosphere is formed between the rain shield 4 and the top cover 3, so that the heat in the cylinder 2 can be dissipated to the outside atmosphere through the heat dissipation gap, while preventing rain and snow from entering the inside of the cylinder 2. The wind-assisted rotor ventilation and heat dissipation device has a simple structure, good heat dissipation and ventilation effect, and low manufacturing cost, and is suitable for practical application.

[0052] Embodiment 2

[0053] This embodiment proposes a wind-assisted rotor ventilation and heat dissipation device, such as Figure 5 and Figure 6 As shown, the difference between the wind-assisted rotor ventilation and heat dissipation device and the wind-assisted rotor ventilation and heat dissipation device in the first embodiment is that the wind-assisted rotor ventilation and heat dissipation device in this embodiment has a reinforcement component 6.

[0054] In order to further improve the structural strength of the rain shield 4 to cope with severe weather, the wind-assisted rotor ventilation and heat dissipation device in this embodiment may further include a reinforcement component 6. Figure 5 and Figure 6 As shown, the reinforcement assembly 6 is arranged on the lower surface of the rain shield 4, between the rain shield 4 and the top cover 3. Specifically, as Figure 7 As shown, the reinforcement assembly 6 includes an inner lining plate 61 and a reinforcing rib 62. The inner lining plate 61 is arranged between the rain shield 4 and the top cover 3, and enhances the structural strength of the rain shield 4 and assists the rain shield 4 in blocking rain and snow from entering the interior of the cylinder 2. One end of the reinforcing rib 62 is fixedly connected to the lower surface of the rain shield 4, and the other end of the reinforcing rib 62 is fixedly connected to the upper surface of the inner lining plate 61, so as to enhance the connection strength between the rain shield 4 and the inner lining plate 61.

[0055] Optionally, the reinforcing ribs 62 are connected to the rain shield 4 and the inner lining plate 61 by welding. Preferably, in order to improve the structural strength of the rain shield 4 and ensure that the heat in the cylinder 2 can be smoothly dissipated to the outside atmosphere, the number of reinforcing ribs 62 is consistent with the number of support columns 5, and the reinforcing ribs 62 and the support columns 5 are alternately arranged.

[0056] Furthermore, if Figure 7 As shown, the inner lining plate 61 includes a first inner lining plate 611 and a second inner lining plate 612 connected at a second preset angle. Specifically, the first inner lining plate 611 is an annular plate, which is arranged on the inner side of the second inner lining plate 612. The second inner lining plate 612 is an annular inclined plate, and the end of the second inner lining plate 612 away from the first inner lining plate 611 is inclined downward toward the direction of the top cover 3. In this embodiment, the first preset angle is equal to the second preset angle, so that the inner lining plate 61 can achieve the best effect of assisting the rain shield 4 in blocking rain, while allowing the heat inside the cylinder 2 to flow more smoothly to the external atmosphere, thereby improving the heat dissipation efficiency.

[0057] To prevent stress concentration at the connection of the reinforcing rib 62 and thus damage the rain shield 4 or the inner lining plate 61. A plurality of reinforcing ribs 62 are provided, and the plurality of reinforcing ribs 62 are evenly arranged along the circumferential direction of the first inner lining plate 611, so as to improve the uniformity of the connection force, and at the same time, it is also beneficial for the heat inside the cylinder 2 to be dissipated to the external atmosphere in time through the heat dissipation gap between the support column 5 and the reinforcing rib 62.

[0058] In order to increase the wind resistance of the wind-assisted rotor ventilation and heat dissipation device in this embodiment, preferably, the first inner lining plate 611 and the second inner lining plate 612 in this embodiment are integrally formed.

[0059] The wind-assisted rotor ventilation and heat dissipation device provided in this embodiment covers the manhole 1 of the top cover 3 with a rain shield 4, and the rain shield 4 and the top cover 3 are spaced to form a heat dissipation gap connected to the outside atmosphere, so that the heat in the cylinder 2 can be dissipated to the outside atmosphere through the heat dissipation gap, while preventing rain and snow from entering the inside of the cylinder 2. The structural strength of the ventilation and heat dissipation device itself can be enhanced by adding a reinforcement component 6, and the rain and snow protection effect can be further enhanced. The wind-assisted rotor ventilation and heat dissipation device has a simple structure, good heat dissipation and ventilation effect, and low manufacturing cost, and is suitable for practical application.

[0060] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
