Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation in a fan cabin, and in particular to a device for processing catkin dust in a fan cabin. Background Art

[0002] Willow catkins have the characteristics of low density, fluffy texture and large specific surface area. After flying into the wind turbine cabin in the windy season, they are very easy to adhere to the surface of the oil cooling radiator, affecting the heat dissipation of the wind turbine gearbox, and then causing the gearbox temperature to rise and affect the output of the wind turbine. Taking a certain brand of 1.5MW doubly fed wind turbine as an example, when the gearbox oil temperature exceeds 75 degrees, the unit starts to operate at limited power. Under continuous high wind speed and high load operation, the gearbox oil temperature cannot be effectively reduced. When the temperature exceeds 80 degrees, the unit will shut down due to over-temperature.

[0003] At present, there are measures such as adding filters to radiators to prevent poplar and willow catkins from adhering to the surface of radiators, but it is necessary to regularly climb the tower to clean or even wash the surface of the radiator to achieve the cleaning purpose.

The filter is replaced by rotating the active roller and the passive roller, and the active roller and the passive roller can be manually rotated by rotating the connector for manual adjustment, and the active roller and the passive roller can be conveniently disassembled and replaced by connecting the rotating connector with the active roller and the passive roller;

[0004] However, since the use of the filter cannot effectively filter out dust and lint, and replacing the filter at high altitude is dangerous, the invention cannot fundamentally solve the problem of purifying the fan cooling gas. Summary of the invention

[0005] In view of the above-mentioned problems existing in the existing willow catkin dust processing device in the fan cabin, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a device for handling willow catkin dust in a wind turbine cabin, which aims to: willow catkins, due to their low density, fluffy texture and large specific surface area, are easy to adhere to the surface of the oil cooling radiator after flying into the wind turbine cabin in the windy season, affecting the heat dissipation of the wind turbine gearbox, causing the gearbox temperature to rise, and affecting the output of the wind turbine. In the prior art, although there are ways to prevent willow catkins from adhering to the radiator surface by installing a filter net, it needs to be cleaned regularly, which is dangerous.

[0007] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a willow catkin dust processing device in a fan cabin, comprising a pipe, the pipe is provided with multiple bends, an air induction component and an electrostatic precipitator component are arranged in the pipe, and a detachable dust bag is arranged on the pipe, and the dust bag corresponds to the position of the electrostatic precipitator component.

[0009] As a preferred solution of the device for handling catkin dust in a fan cabin of the present invention, the electrostatic precipitator component includes a plurality of electrode plates which are equally spaced and arranged in parallel, and the electrode plates are mounted on the inner wall of the first cavity through a bracket.

[0010] As a preferred solution of the willow catkin dust processing device in the fan cabin of the present invention, an air inlet and an air outlet are arranged in the first cavity, the air inlet is arranged opposite to the air outlet, and the air inlet is higher than the air outlet.

[0011] As a preferred solution of the catkin dust processing device in the fan cabin of the present invention, wherein: in the first cavity, air flows from the air inlet to the air outlet, and the electrode plate is perpendicular to the path of air flow.

[0012] As a preferred solution of the willow catkin dust processing device in the fan cabin of the present invention, a one-way valve is arranged in the drop-out port, and the one-way valve opens outwardly toward the first cavity.

[0013] As a preferred solution of the willow catkin dust processing device in the fan cabin of the present invention, the pipeline is divided into a first section, a first cavity, a second section and a second cavity in sequence, and the first section and the second section are arranged in a bent shape.

At this time, the power supply of the electrostatic precipitator component is cut off, the gas enters the cabin through the heat dissipation holes, and the one-way valve opens, causing the impurities in the first cavity and the impurities intercepted by the second filter to fall into the dust bag below with the airflow. At the same time, the impurities attached to the first filter will also be blown into the atmosphere to purify the surface of the filter. This design effectively reduces the accumulation of impurities in the cabin and improves the cleanliness of the equipment. The introduction of the high-speed fan back-blowing function further enhances the self-cleaning ability of the device and reduces the need for manual cleaning.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Example 1

[0036] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a device for handling catkin dust in a fan cabin, including a pipe 100, the pipe 100 is provided with multiple bends, an air induction component 200 and an electrostatic precipitator component 300 are provided in the pipe 100, and a detachable dust bag 400 is provided on the pipe 100, and the dust bag 400 corresponds to the position of the electrostatic precipitator component 300.

[0037] In this embodiment, the fan cabin is a relatively closed space. In the early design, for heat dissipation and ventilation, we designed specific openings on the cabin cover at both ends of the gearbox radiator, and installed rain covers to protect the internal components. The gearbox radiator fan is located on the top of the cabin, and its function is to exhaust hot air out of the cabin and discharge it into the atmosphere. When the fan is running, a negative pressure is formed inside the cabin, which causes the outside air to be sucked into the cabin through these openings. However, this design also brings problems: as impurities such as catkins and dust in the outside air are sucked in, they will gradually adsorb on the surface of the gearbox oil cooling radiator, blocking the gaps between the heat sinks, thereby affecting the heat dissipation efficiency of the unit.

[0038] In order to solve the above problems, we have developed a device for handling catkin dust in a fan cabin. The core of the device is an additional channel system, which uses the negative pressure generated when the high-speed fan 201 of the gear box in the cabin is started to guide the external air into the cabin through a specific path.

[0039] Specifically: When the high-speed fan 201 of the gearbox is started, a negative pressure is formed inside the cabin. At this time, the outside air is sucked into the cabin through the openings on the cabin cover. The outside air first passes through the first filter 105 of the first section 102. This filter can intercept larger particles, such as dust and some catkins; then enters the first cavity 101, and the air after preliminary filtration enters an electrostatic precipitator component 300. The technology here can effectively remove fine particles in the air, including remaining catkins. The clean air processed by the electrostatic precipitator component 300 flows directly into the second section 103, and is first filtered and intercepted again by the second filter 106 on the second section 103, and then enters the second cavity 104 and the cabin through the second section 103 to provide the required cooling for the gearbox radiator.

[0040] The most important of these is that the fan back-blowing function is performed before the fan is started. When the high-speed fan 201 back-blows, the power supply of the electrostatic precipitator component 300 is cut off and the gas enters the cabin through the heat dissipation hole 107. The one-way valve 401 opens and the impurities inside the first cavity 101 and the impurities intercepted by the second filter 106 are all blown into the dust bag 400 below by the wind. At the same time, the impurities attached to the first filter 105 are blown into the atmosphere with the airflow to purify the surface of the first filter 105.

[0041] With the above design, we can not only effectively prevent impurities such as catkins and dust from entering the cabin, but also ensure that the air entering the cabin is clean, thereby improving heat dissipation efficiency, extending the service life of the equipment, and reducing maintenance costs. In addition, the installation and maintenance of this device are relatively simple, and there is no need to frequently replace the filter, which greatly reduces the risk of high-altitude operations. The fan backwash function further enhances the self-cleaning ability of the device, reduces the need for manual cleaning, and improves the operating efficiency and safety of the entire system.

[0042] Example 2

[0043] Reference Figure 1-Figure 4, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the duct 100 system in the present invention is carefully designed to ensure the efficiency of air flow and dust removal effect. The duct 100 is divided into four main parts: the first section 102, the first cavity 101, the second section 103 and the second cavity 104, wherein the first section 102 and the second section 103 are specially designed to be bent, and such a design has the following purposes and effects: the bent design helps to control the direction and speed of air flow, so that the air can flow more evenly and orderly when passing through the duct 100, thereby improving the dust removal efficiency. The bending design of the first section 102 and the second section 103 increases the contact time and contact area between the air and the filter, so that the filter can more effectively intercept and collect impurities in the air, such as dust and catkins. Through the bending design, a longer duct 100 path can be achieved in a limited cabin space without significantly increasing the size of the cabin, which helps to maintain the compactness of the cabin. The bent pipe 100 can act as a physical barrier to prevent large particles of debris from directly entering the electrostatic precipitator component 300, reduce damage to the electrostatic precipitator component 300, and improve the safety and reliability of the system. The bent design makes it easier for the pipe 100 to adapt to the complex spatial layout in the fan cabin, and is also convenient for installation and maintenance. Reasonable bending design can reduce pressure loss during air flow and improve the energy efficiency of the entire system.

[0044] In summary, the design of the duct 100 not only improves the air purification efficiency, but also enhances the heat dissipation performance of the cabin. By optimizing air flow and increasing the filtering effect, this design helps to improve the overall performance of the catkin dust treatment device in the wind turbine cabin, ensuring the stable operation and safety of the wind turbine. At the same time, this design also makes the installation and maintenance of the device more convenient, reducing maintenance costs and the risk of high-altitude operations.

[0045] Function and design of the filter screen. In the catkin dust treatment device in the fan cabin of the present invention, a two-stage filtering system is specially designed, namely the first filter screen 105 and the second filter screen 106, which are respectively installed at the first section 102 and the front end of the second section 103 of the pipeline 100. This design is intended to more effectively remove impurities in the air through multiple stages of filtering, ensuring that the air entering the cabin is as clean as possible.

[0046] The first filter 105 is located at the front end of the first section 102, and its main function is to intercept larger particles, such as dust and some catkins. This layer of filter, as a primary filter, can reduce the larger impurities entering the cabin and reduce the burden of the subsequent electrostatic precipitator 300. The second filter 106 is located at the front end of the second section 103, and its function is to re-filter the air after being processed by the electrostatic precipitator 300. This layer of filter can intercept any fine particles that may not be captured by the electrostatic precipitator 300, ensuring that the air reaches a higher cleanliness before entering the cabin.

[0047] The external air first passes through the first filter 105, and this stage mainly removes larger particles. Subsequently, the air enters the first cavity 101 and flows into the electrostatic precipitator 300. This technology effectively removes fine particles in the air, including the remaining catkins. The clean air treated by the electrostatic precipitator 300 flows directly into the second section 103. At this time, the second filter 106 filters and intercepts the air again to ensure the cleanliness of the air. In addition, before the fan is started, the device is designed with a fan back-blowing function. This function is activated when the high-speed fan 201 back-blows. At this time, the power supply of the electrostatic precipitator 300 is cut off and stops working. The gas enters the cabin through the heat dissipation hole 107, and the one-way valve 401 is opened, and the impurities inside the first cavity 101 and the impurities intercepted by the second filter 106 fall into the dust bag 400 below with the wind. At the same time, the impurities attached to the first filter 105 are blown into the atmosphere with the air flow, thereby purifying the surface of the first filter 105.

[0048] This design not only improves the efficiency of air purification, but also realizes self-cleaning of the filter screen through the fan back-blowing function, reduces the need for manual cleaning, and reduces maintenance costs and operational risks. Through this multi-stage filtration and self-cleaning mechanism, the present invention effectively protects the internal components of the wind turbine cabin and improves the stability and reliability of the wind turbine set.

[0049] The air induction component 200 is disposed in the second cavity 104 and is used for suction and heat dissipation. The air induction component 200 includes a high-speed fan 201 and a heat sink 202 for dissipating heat from the high-speed fan 201, and a heat dissipation hole 107 connected to the outside is opened on the outer wall of the second cavity 104.

[0050] In the device for treating willow catkin dust in a fan cabin of the present invention, the air induction component 200 is arranged in the second cavity 104 and is mainly used for air suction and heat dissipation. The core components of the air induction component 200 include a high-speed fan 201 and a heat sink 202 . The function of the high-speed fan 201 is to generate a strong airflow to draw outside air into the cabin, thereby forming a negative pressure and promoting air flow. The high-speed fan 201 is a device in the existing fan cabin and does not need to be added additionally. The advantage is that there is no need to purchase and install a new high-speed fan 201, which directly reduces the initial investment cost and operating cost of the device. Since the existing equipment is used, the installation steps of additional equipment are omitted, the installation process is simplified, the engineering time is shortened, and the additional space occupation required for the addition of new equipment is avoided, making the space layout in the cabin more compact and efficient. The maintenance personnel are already familiar with the existing equipment and can perform maintenance without additional training, which reduces the difficulty and cost of maintenance. The compatibility issues between the existing equipment and the willow catkin dust treatment device in the cabin are reduced, reducing the risk of system integration. By optimizing the use of existing equipment, the overall energy efficiency of the fan cabin is improved, making the equipment operation more economical, no additional equipment is required, and the interference that the new equipment may cause to other components in the cabin is reduced, reducing the potential risk of failure. The willow catkin dust treatment device in the new cabin can be quickly deployed using existing equipment, which accelerates the speed of technology upgrading and problem solving. At the same time, the heat sink 202 is responsible for effectively dissipating the heat of the high-speed fan 201, ensuring that the fan will not be affected by overheating when running at high speed and its performance and life. In addition, heat dissipation holes 107 connected to the outside are opened on the outer wall of the second cavity 104. These heat dissipation holes 107 can help discharge the heat generated during the operation of the fan to maintain the temperature inside the cabin stable, and at the same time, they are used as air inlets 101a during backblowing.

[0051] The remaining structures are the same as those of Example 1.

[0052] Example 3

[0053] Reference Figure 1-Figure 4 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the duct 100 is provided with a first cavity 101, and an air inlet 101a and an air outlet 101b are provided in the first cavity 101, the air inlet 101a and the air outlet 101b are arranged opposite to each other, and the air inlet 101a is higher than the air outlet 101b, and the electrostatic precipitator 300 is located in the first cavity 101. The electrostatic precipitator 300 includes a plurality of electrode plates 301 that are arranged in parallel at equal intervals, and the electrode plates 301 are mounted on the inner wall of the first cavity 101 through a bracket, and in the first cavity 101, air flows from the air inlet 101a to the air outlet 101b, and the electrode plates 301 are perpendicular to the path of air flow.

[0054] It needs to be explained that: the first cavity 101 is provided with an air inlet 101a and an air outlet 101b, the two air outlets are arranged oppositely, and the position of the air inlet 101a is higher than the air outlet 101b. This design helps to control the direction and speed of air flow, so that the air can enter and leave the first cavity 101 in an orderly manner. In the first cavity 101, air flows from the air inlet 101a to the air outlet 101b, and the electrode plate 301 is perpendicular to the path of air flow. This layout enables impurities in the air to be captured and adsorbed by the electric field generated by the electrode plate 301 when passing through the electrostatic precipitator component 300, thereby achieving air purification. The electrostatic precipitator component 300 is located in the first cavity 101, and it includes a plurality of electrode plates 301 distributed in parallel at equal intervals. These electrode plates 301 are mounted on the inner wall of the first cavity 101 by a bracket to ensure that the electrode plates 301 are fixed and stable.

[0055] The working principle of the electrostatic precipitator 300 is based on electrostatic precipitator technology. When air carrying impurities such as dust and catkins passes through the first cavity 101, the electric field generated by the electrode plate 301 charges these particles. The charged particles are then adsorbed onto the electrode plate 301 and separated from the air. This process effectively removes fine particles in the air and improves the cleanliness of the air.

[0056] Through this design, the present invention not only improves the efficiency of air purification, but also effectively removes fine particles in the air through electrostatic precipitator technology. The application of this technology, combined with the fan back-blowing function and multi-stage filtration system, enables the air in the fan cabin to be fully purified. Such a design not only protects the internal components of the fan cabin from the influence of impurities, but also improves the stability and reliability of the wind turbine, while also reducing maintenance costs and operational risks.

[0057] A material drop opening 101c communicating with the outside is provided at the lowest point of the first cavity 101 , a dust collecting bag 400 is installed outside the material drop opening 101c , a one-way valve 401 is provided inside the material drop opening 101c , and the one-way valve 401 opens outward from the first cavity 101 .

[0058] In the catkin dust treatment device in the wind turbine cabin of the present invention, the design of the first cavity 101 not only includes the electrostatic precipitator component 300, but also specially provides a drop port 101c and a dust bag 400 to achieve effective collection and treatment of impurities. The lowest point of the first cavity 101 is provided with a drop port 101c connected to the outside world. This design utilizes the principle of gravity so that the impurities in the first cavity 101 can fall naturally and be discharged to the outside of the cabin through the drop port 101c. The dust bag 400 is installed outside the drop port 101c. The function of this dust bag 400 is to collect impurities discharged from the first cavity 101, prevent these impurities from being directly scattered into the environment, and keep the environment clean. A one-way valve 401 is provided in the discharge port 101c, and the direction of the one-way valve 401 is that the first cavity 101 opens outward, which means that the one-way valve 401 only allows impurities to be discharged from the first cavity 101 to the dust collecting bag 400, and prevents external air from flowing back into the first cavity 101, thereby ensuring the unidirectionality and controllability of the air flow.

[0059] In the fan back-blowing function before the fan is started, the design of the drop port 101c and the one-way valve 401 plays an important role. When the high-speed fan 201 back-blows, the electrostatic precipitator 300 stops working, the gas enters the cabin through the heat dissipation hole 107, and the one-way valve 401 opens, so that the impurities in the first cavity 101 and the impurities intercepted by the second filter 106 fall into the dust bag 400 with the wind. At the same time, the impurities attached to the first filter 105 are blown into the atmosphere with the airflow to purify the surface of the first filter 105.

[0060] Through this design, the present invention not only improves the efficiency of air purification, but also realizes effective collection and treatment of impurities through the arrangement of the drop opening 101c and the dust bag 400. This design not only protects the internal components of the fan cabin from the influence of impurities, but also reduces maintenance costs and operation risks, while also keeping the environment clean.

[0061] The remaining structure is the same as that of Example 2.
