Description

Technical Field

[0001] The utility model relates to the technical field of rain removal for wind turbines, in particular to a compact and efficient rain remover. Background Art

[0002] During the operation of a wind power generation set, a large amount of heat is generated. This heat is discharged into the external atmosphere through a heat exchange system. During the operation of the heat exchange system, a large amount of cold air needs to be inhaled from the atmosphere. When it rains, the air containing a large amount of rainwater is brought into the heat exchanger. It is impossible to achieve 100% sealing inside the rainwater heat exchanger. Long-term operation will cause a large amount of rainwater to leak into the system. Especially in a marine atmospheric environment, the rainwater contains a large amount of corrosive substances, which will eventually cause the electrical equipment and structural components inside the system to be damaged by the rainwater and corrosive substances, and the system cannot operate. In order to prevent rainwater from entering the system, the air intake of the existing equipment is arranged at the bottom of the equipment. The advantage is that the resistance of the gas passing through is small, and the vertically falling raindrops can be directly prevented from entering the system.

[0003] The structures adopted by the most commonly used existing rainwater separators: inertial rain removal and filter screen rain removal. The principle is that the air mixed with rainwater enters the first filter layer of the rainwater separator, that is, the inertial filter layer, to filter out large raindrops, and then passes through the second filter screen to filter out micron-sized raindrops and impurities.

[0004] The current rainwater separator is likely to increase the system resistance, resulting in a decrease in the air volume, affecting the heat exchange performance of the system, and requires regular cleaning or replacement, with a relatively high maintenance cost. Content of the Utility Model

[0005] The purpose of the utility model is to provide a compact and efficient rain remover, aiming to solve the problems that the current rainwater separator is likely to increase the system resistance, resulting in a decrease in the air volume, affecting the heat exchange performance of the system, and requires regular cleaning or replacement, with a relatively high maintenance cost.

[0006] To achieve the above purpose, the utility model provides a compact and efficient rain remover, including a rain-proof louver, an impeller assembly, a motor plate and a motor. The impeller assembly is detachably connected to the rain-proof louver and is located on the inner side wall of the rain-proof louver. The motor plate is bolted to the rain-proof louver and is located above the rain-proof louver. The motor is bolted to the motor plate and is located above the motor plate. The output end of the motor is fixedly connected to the impeller assembly and is located above the impeller assembly, and the output end of the motor penetrates through the motor plate.

[0007] When in use, the motor plate is used to fix the motor, and the motor provides power for the rotation of the impeller assembly. The rotation of the impeller assembly generates centrifugal force to move rainwater in a specified direction. The rainproof louvers are used to intercept rainwater, and then the rainwater is discharged downward under the action of gravity. In this way, the impeller assembly is driven to rotate clockwise, so that the air diffuses radially under the action of centrifugal force, and the radial movement of rainwater is blocked by the rainproof louvers. If it rotates counterclockwise, the rainwater will not move radially, and the air leaving the centrifugal device contacts the baffles around it and falls under the action of gravity. The design will not affect the directional air volume, and the impeller assembly has been redesigned, which is simpler than those on the market. It has its own motor drive to overcome the resistance of the rainproof louver itself, provide sufficient air intake requirements, and achieve separation of rainwater and gas under the action of centrifugal force. The air inlet rain cover can be installed from the cabin on the basis of the existing tower, utilizing the existing installation space without the need to increase the external dimensions. The air inlet wind speed range is large, and the rain removal effect can still be achieved at higher wind speeds. The self-contained power system overcomes its own resistance and does not affect the performance curve of the original system, ensuring that the heat exchange system has sufficient air volume.

[0008] Wherein, the compact and efficient rain remover also includes a layout plate, which is fixedly connected to the rainproof louver and is located on one side of the rainproof louver.

[0009] The arrangement plate is used to fix the rainproof louver, which is convenient for workers to install and use.

[0010] Wherein, the compact and efficient rain remover further comprises a baffle, which is bolted to the arrangement plate and is located on one side of the arrangement plate.

[0011] The baffle is used to shield rainwater, so that the centrifugal rainwater contacts the baffle and falls down due to gravity to be discharged.

[0012] Wherein, the rainproof louver has a plurality of circular holes.

[0013] The circular holes are used to disperse the louvers on the rainproof louvers. The rainproof louvers designed in this shape can work in a smaller space, overcome this part of the resistance through their own motor impellers, provide the cooler with sufficient required air volume, and have higher space utilization. The air and water are separated under the action of centrifugation, which is more efficient.

[0014] Wherein, the impeller assembly has a circular arc chamfer.

[0015] The arc chamfer can eliminate stress concentration points and make stress distribution more uniform, thereby improving the overall strength and durability of the parts or structures and facilitating handling and installation.

[0016] A compact and efficient rain eliminator of the present utility model, when in use, the motor plate is used to fix the motor, the motor provides power for the rotation of the impeller assembly, the rotation of the impeller assembly generates centrifugal force to make the rain move in a specified direction, the rain-proof louvers are used to intercept the rain, and then the rain is discharged downward under the action of gravity. In this way, the impeller assembly is driven to rotate clockwise, so that the air diffuses radially under the action of centrifugal force, and the radially moving rain is blocked by the rain-proof louvers. If it rotates counterclockwise, the rain will not move radially. The air leaving the centrifugal device contacts the surrounding baffles and drops under the action of gravity. Such a design will not affect the directional air volume, and the impeller assembly is also redesigned to be more concise than those on the market. It is self-equipped with a motor drive to overcome the self-resistance of the rain-proof louvers and provide a sufficient air intake demand. Under the action of centrifugal force, the separation of rain and gas is achieved. It can be installed on the air intake rain-proof cover from the nacelle on the basis of the existing tower barrel, making use of the existing installation space without additional external dimensions; the air intake wind speed range is large, and the rain elimination effect can still be achieved at a higher wind speed. It has a self-powered system to overcome its own resistance and does not affect the performance curve of the original system, ensuring that the heat exchange system has sufficient air volume.

The rotation of the impeller assembly 102 generates centrifugal force to move rainwater in a specified direction. The rainproof louver 101 is used to intercept rainwater, and then the rainwater is discharged downward under the action of gravity. In this way, the impeller assembly 102 is driven to rotate clockwise, so that the air is diffused radially under the action of centrifugal force.

[0030] In this embodiment, the arrangement plate 105 is used to fix the rainproof louver 101, which is convenient for workers to install and use.

[0031] Furthermore, the baffle plate 106 is bolted to the arrangement plate 105 and is located on one side of the arrangement plate 105 .

[0032] In this embodiment, the baffle 106 is used to block rainwater, so that the centrifugal rainwater contacts the baffle 106 and falls down due to gravity and is discharged.
