Description

Technical Field

[0001] This utility model relates to the field of power generation technology, and in particular to a dual-channel small wind turbine. Background Technology

[0002] The full utilization of wind energy is crucial in many fields such as energy development, power engineering and ecological protection. High-rise buildings have a good wind energy environment because of their high vertical height and the strong winds relative to the ground.

[0003] Nowadays, building units are often connected by corridors. The gaps between the walls of the corridors are small. Due to the Venturi effect, the air velocity in the corridors increases. This high-velocity air can be used to generate electricity. The inventor has proposed a dual-channel small wind turbine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-channel small wind turbine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-channel small wind turbine generator, comprising a power generation component, the power generation component comprising a housing, the housing having two air inlets on its side, the two air inlets being arranged opposite to each other, a wind turbine being disposed inside the housing, wherein the wind turbine can rotate inside the housing, a generator being mounted on the surface of the housing, and the generator output shaft being connected to the wind turbine central shaft.

[0006] The effect achieved by the above-mentioned components is as follows: due to the Venturi effect, there will be a high-velocity airflow in the corridor or wall gap of a high-rise building. This application installs the casing between two walls, and then sets the two air vents of the casing along the direction of the corridor. When air flows, due to the narrowness of the corridor walls, the Venturi effect will cause the air velocity in the corridor to be large, which will cause the high-speed air to enter along one air vent, drive the wind turbine to rotate, and then be discharged from the other air vent. The rotation of the wind turbine drives the generator to rotate and generate electricity.

[0007] Preferably, the housing includes two sealing plates, which are connected by a side plate. The surfaces of the sealing plates and the side plates are reinforced with ribs. A motor frame is mounted on the surface of the generator, and the motor frame is detachably mounted on the surface of the reinforcing ribs.

[0008] The aforementioned components achieve the following effect: the casing is installed using a sealing plate and side plates, which facilitates assembly and disassembly, thereby making maintenance easier.

[0009] Preferably, the surface of the housing is provided with a supporting member, the supporting member including a clamp installed on the surface of the reinforcing rib, a crossbeam is inserted inside the clamp, and the crossbeam is detachably installed between the two walls of the slit.

[0010] The effect achieved by the above components is that the clamps can detachably attach the crossarm to the surface of the machine housing, and use them to fix the two ends of the crossarm to the walls on both sides of the corridor, thereby enabling the machine housing to be quickly fixed in the corridor.

[0011] Preferably, a slide rod is slidably inserted into the port of the crossarm, wherein a rubber sleeve is fitted on the free end of the slide rod, a baffle is fixedly connected to the surface of the slide rod, a slide cylinder is detachably installed between the crossarms, a screw is slidably connected inside the slide cylinder, the free end of the screw is fixed to the baffle, and a first nut sleeve is rotatably connected to the port of the slide cylinder, the first nut sleeve being threaded onto the surface of the screw.

[0012] The effect achieved by the above components is as follows: by rotating the first nut sleeve, the first nut sleeve drives the screw to adjust the length of the extension in the slide cylinder. The screw drives the baffle to move closer to or away from the housing, so that it can be adjusted according to the actual width requirements of the corridor. This allows it to be installed to suit different corridor requirements. The baffle is provided with bolt holes, and the baffle can be detachably installed on the wall with the help of expansion bolts.

[0013] Preferably, a diagonal bracing member is provided at the bottom of the crossbeam below, and the diagonal bracing member is placed between the bottom of the crossbeam and the wall surface for reinforcement.

[0014] Preferably, the diagonal bracing component includes a diagonal brace rod, the upper end of which is welded with an mounting plate. The diagonal brace rod is detachably installed between the mounting plate and the crossbeam via bolts. The other end of the diagonal brace rod is fixed to the wall.

[0015] The effect achieved by the above components is as follows: the port of the diagonal brace can also be fitted with a lead screw, the free end of which is fitted with a square plate, and the square plate is fixed to the wall by expansion bolts. By rotating the second nut sleeve at the port of the diagonal brace, the extension length of the lead screw can be adjusted to fit the wall for fixing (for example, some walls now have a stepped structure at the top, the crossbeam can be fixed in the narrower area at the top of the step, and the diagonal brace is supported in the wider area at the bottom of the step).

[0016] Preferably, the air vent is provided with a protective component inside, which divides the air vent into multiple gaps to block debris.

[0017] Preferably, the protective component includes multiple intercepting rods, which are arranged in parallel with gaps between them. The ends of the multiple intercepting rods are fixed together by a connecting strip, and the connecting strip is stuck in the air vent when the intercepting rod is inserted into the air vent.

[0018] The effect achieved by the above components is that multiple interceptor bars form a fence structure due to the high-speed airflow.

[0019] Preferably, an assembly strip is installed in the air vent, and an inclined block is installed on the surface of the assembly strip. When the intercepting rod is inserted into the air vent, the assembly strip slides along the inclined surface of the inclined block and gets stuck on the back of the inclined block.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, high-speed air enters through one vent to drive the wind turbine to rotate and then exits through another vent. The rotation of the wind turbine drives the generator to rotate and generate electricity.

[0022] 2. In this utility model, the baffle is driven by a screw to move closer to or further away from the housing, thereby adjusting according to the actual width requirements of the corridor and adapting to different corridor needs for installation. The baffle is provided with bolt holes, and the baffle can be detachably installed on the wall with the help of expansion bolts. Attached Figure Description

[0032] Example 1, such as Figure 1-4As shown, a dual-channel small wind turbine 3 includes a power generation component, which includes a housing 1. Two air inlets are provided on the side of the housing 1, facing each other. A wind turbine 2 is housed inside the housing 1, rotating within it. A generator 3 is mounted on the surface of the housing 1, with its output shaft connected to the central shaft of the wind turbine 2. In high-rise building corridors or wall gaps, high-velocity airflow occurs due to the Venturi effect. This application installs the housing 1 between two walls, and then positions the two air inlets of the housing 1 along the corridor's direction. When airflow occurs, due to the narrow corridor walls and the Venturi effect, the air velocity within the corridor is high, causing the high-speed air to enter through one air inlet, driving the wind turbine 2 to rotate, and then exiting through the other air inlet. Another vent discharges air, and the rotation of the impeller 2 drives the generator 3 to generate electricity. The casing 1 includes two sealing plates 11, which are connected by a side plate 12. Reinforcing ribs are installed on the surfaces of both the sealing plates 11 and the side plate 12. A motor frame 4 is installed on the surface of the generator 3, and the motor frame 4 is detachably mounted on the surface of the reinforcing ribs. The casing 1 is easily assembled and disassembled by the sealing plates 11 and the side plate 12, thus facilitating maintenance. A supporting member 5 is provided on the surface of the casing 1. The supporting member 5 includes a clamp 51 installed on the surface of the reinforcing ribs. A crossbeam 52 is inserted inside the clamp 51. The crossbeam 52 is detachably installed between the two walls of the slit. The clamp 51 allows the crossbeam 52 to be detachably mounted on the surface of the casing 1, thus securing the two ends of the crossbeam 52 to the corridor. On both side walls, the housing 1 can be quickly fixed to the corridor. A slide rod 53 is slidably installed at the port of the crossarm 52, with a rubber sleeve on the free end of the slide rod 53. A baffle 54 is fixedly connected to the surface of the slide rod 53. A slide cylinder 55 is detachably installed between the crossarms 52. A screw 56 is slidably connected inside the slide cylinder 55, with its free end fixed to the baffle 54. A first nut sleeve 57 is rotatably connected to the port of the slide cylinder 55, threaded onto the surface of the screw 56. By rotating the first nut sleeve 57, the screw 57 drives the screw 56 to adjust its extension length within the slide cylinder 55. The screw 56 drives the baffle 54 closer to or further away from the housing 1, thus allowing adjustment according to the actual width requirements of the corridor and adaptability. For different corridor needs, the baffle 54 is equipped with bolt holes, allowing it to be detachably installed on the wall using expansion bolts. A diagonal brace 6 is located at the bottom of the lower crossbeam 52, reinforcing the space between the crossbeam 52 and the wall. The diagonal brace 6 includes a diagonal brace 61, with a mounting plate welded to its upper end. The diagonal brace 61 is detachably installed on the crossbeam 52 via bolts and the mounting plate. The other end of the diagonal brace 61 is fixed to the wall. A threaded rod 62 can also be slidably inserted into the end of the diagonal brace 61. A square plate is installed at the free end of the threaded rod 62, and the square plate is fixed to the wall using expansion bolts. The extension length of the threaded rod 62 can be adjusted by rotating the second nut 63 at the end of the diagonal brace 61.To adapt to the wall for fixation (for example, some walls now have a stepped structure at the top; the crossbeam 52 can be fixed in the narrower area at the top of the step, and the diagonal brace 6 can be supported in the wider area at the bottom of the step).

[0033] Example 2, as Figure 5-6 As shown, a protective component 7 is installed inside the air vent. The protective component 7 divides the air vent into multiple gaps to block debris. The protective component 7 includes multiple intercepting rods 71. The multiple intercepting rods 71 ​​are arranged in parallel and have gaps between them. The ends of the multiple intercepting rods 71 ​​are fixed together by a combination strip 72. When the intercepting rods 71 ​​are inserted into the air vent, the combination strip 72 is stuck in the air vent. The multiple intercepting rods 71 ​​form a fence structure. Due to the high-speed air flow, an assembly strip 73 is installed in the air vent. An inclined block 74 is installed on the surface of the assembly strip 73. When the intercepting rods 71 ​​are inserted into the air vent, the combination strip 72 slides along the inclined surface of the inclined block 74 and is stuck on the back of the inclined block 74.

[0034] Working principle: Due to the Venturi effect, high-velocity airflow occurs in corridors or wall gaps of high-rise buildings. This application installs the casing 1 between two walls, and sets the two air vents of the casing 1 along the corridor's direction. When airflow occurs, the narrow corridor walls and the Venturi effect result in a high air velocity within the corridor. This high-speed airflow enters through one vent, driving the impeller 2 to rotate, and then exits through the other vent. The rotation of the impeller 2 drives the generator 3 to generate electricity. The casing 1 is assembled and disassembled using a sealing plate 11 and side plates 12, facilitating maintenance. A clamp 51 allows the crossarm 52 to be detachably mounted on the surface of the casing 1, securing both ends of the crossarm 52 to the corridor walls, thus quickly fixing the casing 1 to the corridor. By rotating the first nut sleeve 57, the first nut sleeve 57 drives the screw... The extension length of rod 56 is adjusted in the slide cylinder 55. The screw 56 drives the baffle 54 to move closer to or away from the housing 1, thereby adjusting according to the actual width requirements of the corridor and adapting to different corridor needs for installation. The baffle 54 is provided with bolt holes, and the baffle 54 can be detachably installed on the wall with the help of expansion bolts. The end of the diagonal brace 61 can also be fitted with a lead screw 62. The free end of the lead screw 62 is fitted with a square plate, and the square plate is fixed to the wall with expansion bolts. By rotating the second nut sleeve 63 at the end of the diagonal brace 61, the extension length of the lead screw 62 can be adjusted to adapt to the wall for fixing (for example, some walls now have a stepped structure at the top, the crossbeam 52 can be fixed in the narrower area at the top of the step, and the diagonal brace 6 is supported in the wider area at the bottom of the step). Multiple intercepting rods 71 ​​form a fence structure due to the high-speed airflow.
