Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a wind power generation device for use in mining areas. Background Technology

[0002] Currently, in mining areas, due to the remote and complex terrain, power cannot be supplied via cables. Some mining areas often rely on wind power generation equipment to generate electricity and maintain normal living and production needs. However, the complex topography of mining areas makes installing wind power generation equipment particularly difficult. Wind turbines are green power generation devices that convert wind energy into electrical energy.

[0003] With the increasing capacity of individual units and the increasingly harsh high-temperature environment in which some units operate, it is necessary to cool down the wind turbine generators.

[0004] Currently, the industry mostly uses air cooling for the heat dissipation of the entire machine. Air cooling requires the wind turbine to exchange air with the outside environment. However, most wind turbines installed on land are in harsh environments where the air contains a large amount of dust, smoke and other particles. These particles will contaminate the internal components of the wind turbine, thereby affecting the stability and service life of each component.

[0005] Therefore, in existing technologies, most wind turbine ventilation systems use air filter cotton devices for dust removal. However, the dust removal efficiency of these devices decreases over time, and the air filter cotton can become completely clogged after a certain period. This can cause the ventilation and cooling system of the turbine to fail, affecting the normal operation of the wind turbine and increasing maintenance costs. Furthermore, adding air filter cotton at the ventilation system inlet increases the system's resistance, requiring a more powerful motor or fan, which in turn leads to increased energy consumption.

[0006] Therefore, we propose a wind power generation device for mining areas to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in the prior art by proposing a wind power generation device for mining areas.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: It includes a housing, within which a motor is installed; a lifting plate is located above the housing; dust removal mechanisms are located on both sides of the motor; a connecting rod is mounted on the dust removal mechanism; the upper end of the connecting rod penetrates the inner top of the housing and is fixedly connected to the lower end of the lifting plate; an opening is located at the lower end of the housing; a collection box is installed at the lower end of the housing; a negative pressure mechanism that generates negative pressure at the opening is installed inside the housing; and an air supply mechanism is located on the side wall of the housing.

[0009] In the aforementioned wind power generation device for mining areas, the dust removal mechanism includes a scraper fixedly connected to the lower end of a connecting rod. The scraper has multiple strip grooves evenly distributed on the side near the motor. Springs are installed in the strip grooves, and a mounting plate is installed on each strand of the spring. Brush bristles are evenly distributed on the mounting plate.

[0010] In the aforementioned wind power generation device for mining areas, the negative pressure mechanism includes a pump cylinder fixedly connected to the bottom of the housing. A sliding plug is slidably connected inside the pump cylinder, and a one-way valve is installed on the sliding plug. A push rod is fixedly connected to the upper end of the sliding plug. The upper end of the push rod passes through the inner top of the housing and is fixedly connected to the lower end of the lifting plate. The lower end of the pump cylinder is connected to the collection box through an air guide pipe.

[0011] In the aforementioned wind power generation device for mining areas, the side wall of the casing is provided with a ventilation opening, and a dustproof net is installed at the ventilation opening.

[0012] In the aforementioned wind power generation device for mining areas, the air supply mechanism includes an opening in the side wall of the housing, an axial flow fan blade is provided at the opening, a gear is fixedly connected to the output shaft of the axial flow fan blade, a crossbar is fixedly connected to the side wall of the push rod, and a rack is fixedly connected to the end of the crossbar away from the push rod, the rack meshing with the gear.

[0013] In the aforementioned wind power generation device for mining areas, the gear is connected to the output shaft of the axial flow fan blade via a one-way bearing.

[0014] In the aforementioned wind power generation device for mining areas, the lifting plate is wing-shaped, and the end of the lifting plate located on the motor input shaft is lower than the other end.

[0015] Compared with existing technologies, the beneficial effects of the present invention are as follows:

[0016] 1. When the wind picks up, the motor works, and the lifting plate moves up. As the wind force changes constantly and the fan blades rotate, the wind force on the lifting plate changes constantly. The lifting plate will move back and forth, which in turn drives the scraper to move back and forth. The scraper moves back and forth, which drives the brush to clean the dust off the outer wall of the motor.

[0017] 2. Because the motor has a strong magnet, the magnetic flux passing through the spring changes continuously during the reciprocating motion of the scraper, which in turn induces a current in the spring. The spring with the induced current will contract, and the spring that continuously generates the induced current will contract and return to its original state, thereby driving the bristles to clean the surface of the motor by moving back and forth.

[0018] 3. The lifting plate moves up and down repeatedly, which drives the sliding block to move up and down through the push rod. The sliding block moves up and down and draws out the air in the collection box through the air duct, thereby creating negative pressure at the opening and adsorbing the dust brushed out by the bristles.

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] Example

[0025] Reference Figure 1-3 A wind power generation device for mining areas includes a housing 1, a motor installed inside the housing 1, a lifting plate 14 installed above the housing 1, dust removal mechanisms installed on both sides of the motor, a connecting rod 13 installed on the dust removal mechanism, the upper end of the connecting rod 13 penetrating the inner top of the housing 1 and fixedly connected to the lower end of the lifting plate 14, an opening 5 provided at the lower end of the housing 1, a collection box 4 installed at the lower end of the housing 1, a negative pressure mechanism installed inside the housing 1 to generate negative pressure at the opening 5, and an air supply mechanism provided on the side wall of the housing 1.

[0026] The dust removal mechanism includes a scraper 2 fixedly connected to the lower end of the connecting rod 13. The scraper 2 has multiple strip grooves 15 evenly distributed on the side near the motor. Springs 16 are installed in the strip grooves 15. Each spring wire of the spring 16 is equipped with a mounting plate 18. Brush bristles 17 are evenly distributed on the mounting plate 18. When the wind blows, the motor works, and the lifting plate 14 moves upward. Due to the continuous change in wind force and the rotation of the fan blades, the wind force received by the lifting plate 14 changes continuously. The lifting plate 14 will reciprocate, which in turn drives the scraper 2 to reciprocate. The reciprocating motion of the scraper 2 drives the brush bristles 17 to clean the outer wall of the motor.

[0027] Because the motor has a strong magnet, the magnetic flux passing through the spring 16 changes continuously during the reciprocating motion of the scraper 2, which in turn induces a current in the spring 16. The spring 16 with the induced current will contract, and the spring 16 that continuously generates induced current will cause the spring to contract and return to its original state, thereby driving the bristles 17 to clean the surface of the motor by reciprocating back and forth.

[0028] The negative pressure mechanism includes an air pump cylinder 20 fixedly connected to the bottom of the housing 1. A sliding plug 8 is slidably connected inside the air pump cylinder 20. A one-way valve 6 is installed on the sliding plug 8. A push rod 12 is fixedly connected to the upper end of the sliding plug 8. The upper end of the push rod 12 passes through the inner top of the housing 1 and is fixedly connected to the lower end of the lifting plate 14. The lower end of the air pump cylinder 20 is connected to the collection box 4 through the air guide pipe 7. The lifting plate 12 moves up and down, which drives the sliding plug 8 to move up and down through the push rod 12. The up and down movement of the sliding plug 8 draws out the air in the collection box 4 through the air guide pipe 7, thereby creating a negative pressure at the opening 5, which adsorbs the dust brushed by the bristles 17.

[0029] Ventilation openings are provided on the side wall of the housing 1, and dustproof nets 3 are installed at the ventilation openings.

[0030] The air supply mechanism includes an opening 10 on the side wall of the housing 1, an axial flow fan blade 9 is provided at the opening 10, a gear 19 is fixedly connected to the output shaft of the axial flow fan blade 9, a crossbar is fixedly connected to the side wall of the push rod 12, and a rack 11 is fixedly connected to the end of the crossbar away from the push rod 12, and the rack 11 meshes with the gear 19.

[0031] Gear 19 is connected to the output shaft of axial flow fan blade 9 via a one-way bearing.

[0032] The lifting plate 14 is wing-shaped, and the end of the lifting plate 14 located on the motor input shaft is lower than the other end.

[0033] Although this document frequently uses terms such as 1. housing, 2. scraper, 3. dustproof net, 4. collection box, 5. opening, 6. one-way valve, 7. air guide pipe, 8. sliding plug, 9. axial flow fan blade, 10. opening, 11. rack, 12. push rod, 13. connecting rod, 14. lifting plate, 15. slot, 16. spring, 17. bristles, 18. mounting plate, 19. gear, and 20. pump cylinder, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
