Description

Technical Field

[0001] This utility model belongs to the field of wind power generation, specifically relating to the design of a multi-stage series high-efficiency wind power generation device. Background Technology

[0002] Electricity is the foundation of economic development, and wind energy is a clean and environmentally friendly energy source. Wind power generation has many advantages over thermal power generation and nuclear power generation. As an alternative energy source, wind power can supply electricity to one or several households or be connected to the power grid to provide electricity. The size and number of generators can be flexibly selected according to needs.

[0003] A search revealed an existing patent (publication number: CN108915954A) that discloses a multi-stage series high-efficiency wind power generation device, including a support base, a workbench, support columns, a guide duct, an air amplifier, a jet nozzle, an impeller, a generator, wind speed and direction sensors, and a control circuit. The workbench is located directly above the support base and is connected to the support columns. The guide duct, air amplifier, and jet nozzle are all connected to the upper surface of the workbench via guide rails. The air amplifier is located between two adjacent guide ducts and is connected to the guide ducts via the jet nozzle. The impeller and generator are both embedded within the guide ducts. This invention can effectively improve the wind power utilization range of wind power generation operations, increase the efficiency of power generation operations, and improve the stability of equipment operation. Furthermore, it can effectively improve the resistance of wind power generation equipment to harsh natural environments, and improve the stability and reliability of equipment operation. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:

[0004] When existing wind power generation devices experience internal problems requiring maintenance, especially those as tall as utility poles, workers typically need to climb the poles wearing foot straps. However, these foot straps are prone to slipping in rain, snow, frost, or other adverse conditions. Furthermore, for individuals with larger or smaller feet, wearing the same standard foot straps can easily cause them to loosen and fall off during pole climbing, leading to safety accidents. Therefore, it is necessary to install additional foot straps to facilitate more stable and safer maintenance by maintenance teams.

[0005] Therefore, a multi-stage series high-efficiency wind power generation device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a multi-stage series high-efficiency wind power generation device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage series high-efficiency wind power generation device, including a shell and a support column, wherein a maintenance-friendly mechanism is fixedly connected to one side of the bottom of the support column, the maintenance-friendly mechanism including a lead screw, an extension plate, a reserved groove, a sleeve plate, a fixing plate, a servo motor, an auxiliary column, a moving sleeve, and a limiting column.

[0011] Preferably, the number of reinforcing plates is three, and the three reinforcing plates are distributed at equal distances on the connecting plate.

[0012] Preferably, a movable shaft extends through the middle of one side of the housing, a gearbox is mounted on the other side of the movable shaft, and a generator assembly is connected to the other side of the gearbox via a rotating shaft.

The device is approximately the same height as a utility pole. When maintenance is needed, the worker stands on the sleeve plate and remotely starts the servo motor, which rotates the lead screw. This rotates the moving sleeve, which moves along the lead screw and auxiliary column, causing the sleeve and extension plate to move upwards. The upper end of the lead screw is then raised. When the worker is still a short distance from the maintenance door, they push the extension plate, which moves upwards within the sleeve plate to the desired position. The corresponding reserved slot aligns with the limiting slot on the sleeve plate. The worker then inserts the limiting column into the limiting slot, which then passes through the corresponding reserved slot, facilitating stable and safe maintenance.

[0018] 2. Compared with existing technologies, this multi-stage series high-efficiency wind power generation device, through the relationship between the fixed frame, connecting plate, reinforcing plate, collection box and fan, generates a large amount of heat when the internal generator component generates electricity. When the fan starts, the fan generates wind power, and the rear end of the fixed frame has an air inlet, and one side of the connecting plate is hollow, which blows the air into the collection box. The collection box is conical, which can gather the air and thus better dissipate heat. Attached Figure Description

[0026] Example 1

[0027] As attached Figure 1 and Figure 3 , Figure 4 The multi-stage series high-efficiency wind power generation device shown includes a housing 5 and a support column 8. A maintenance-friendly mechanism 9 is fixedly connected to one side of the bottom of the support column 8. The maintenance-friendly mechanism 9 includes a lead screw 901, an extension plate 902, a reserved slot 903, a sleeve plate 904, a fixing plate 905, a servo motor 906, an auxiliary column 907, a movable sleeve 908, and a limiting column 909.

[0028] The bottom of the lead screw 901 is connected to a servo motor 906 via a coupling. The outer wall of the lead screw 901 is threaded with a movable sleeve 908. An auxiliary column 907 is movably connected to one side of the movable sleeve 908. A fixed plate 905 is fixedly connected to the other side of the movable sleeve 908. A sleeve plate 904 is fixedly connected above the fixed plate 905. An extension plate 902 is movably connected above the sleeve plate 904.

A heat dissipation mechanism 6 is fixedly connected to one side of the inside of the housing 5.

[0029] The process involves rotating the lead screw 901, which in turn moves the movable sleeve 908 on the lead screw 901 and the auxiliary column 907. This movement causes the sleeve plate 904 and the extension plate 902 to move upwards. The upper end of the lead screw 901 then moves upwards. When the operator is still a short distance from the maintenance door 7, they push the extension plate 902. The extension plate 902 then moves upwards inside the sleeve plate 904. After moving to the desired position, the corresponding reserved slot 903 aligns with the limiting slot on the sleeve plate 904. The operator then inserts the limiting column 909 into the limiting slot, which then passes through the corresponding reserved slot 903. The operator then climbs onto the extension plate 902. There are pedals on the extension plate 902 and the sleeve plate 904. The lead screw 901 is connected to the upper limiting component by a bushing, and the auxiliary column 907 is fixedly connected to the housing of the servo motor 906.

[0032] In a preferred embodiment, the heat dissipation mechanism 6 includes a fixing frame 601, a connecting plate 602, a reinforcing plate 603, a converging box 604, and a fan 605. The front end of the connecting plate 602 is fixedly connected to the reinforcing plate 603, and the fixing frame 601 is fixedly connected to one side of the reinforcing plate 603. One side of the connecting plate 602 is hollow, and the air is blown into the converging box 604. The converging box 604 is conical, so the air can be gathered.

[0033] As a preferred embodiment, a collection box 604 is fixedly connected inside the mounting bracket 601, and a fan 605 is fixedly connected to one side of the inside of the collection box 604. Through the relationship between the collection box 604 and the fan 605, the wind power can be better collected during later use.

[0034] In a preferred embodiment, there are three reinforcing plates 603, which are evenly distributed on the connecting plate 602. The relationship between the connecting plate 602 and the reinforcing plates 603 allows for better connection during later use.

[0035] As a preferred embodiment, a movable shaft 2 is movably passed through the middle of one side of the housing 5, and a gearbox 3 is installed on the other side of the movable shaft 2. The other side of the gearbox 3 is connected to the generator assembly 4 via a rotating shaft. Through the relationship between the gearbox 3 and the generator assembly 4, power generation can be better performed in later use.

[0036] In a preferred embodiment, a connecting component 1 is fixedly connected to one end of the movable shaft 2, a blade 10 is fixedly connected to the lower part of the connecting component 1, and a maintenance door 7 is installed at the upper front end of the support column 8. The support column 8 is fixedly connected to the housing 5.

[0037] In a preferred embodiment, the fixed plate 905 forms a lifting mechanism through the movable sleeve 908, the lead screw 901, and the servo motor 906. The movable sleeve 908 and the auxiliary column 907 are connected by a sleeve. Through the relationship between the fixed plate 905, the movable sleeve 908, the lead screw 901, and the servo motor 906, the fixed plate 905 can be better driven to move upward during later use.

[0038] In a preferred embodiment, the extension plate 902 and the sleeve plate 904 are connected by a sleeve, and the number of reserved slots 903 is multiple sets, which are distributed at equal intervals on the extension plate 902.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] The working process of this utility model is as follows:

[0041] First, the multi-stage series high-efficiency wind power generation device is installed in the required area, at approximately the same height as the utility pole. Wind then blows the blades 10, causing the connecting assembly 1 to rotate, which in turn rotates the movable shaft 2. Speed ​​is adjusted via the gearbox 3, which in turn drives the generator assembly 4 to generate electricity. During power generation, the generator assembly 4 produces a large amount of heat. When the fan 605 starts, it generates wind. The mounting bracket 601 has an air inlet at its rear end, and one side of the connecting plate 602 is hollow. The wind is then blown into the converging box 604, which is cone-shaped, to gather the air and direct it onto the generator assembly 4 for heat dissipation. The heat is then dissipated through the heat dissipation vent at the front of the casing 5. When maintenance is required, the operator stands on the sleeve plate 904 and then uses a remote control... The servo motor 906 is started, which drives the lead screw 901 to rotate. This causes the moving sleeve 908 to move on the lead screw 901 and the auxiliary column 907, which in turn moves the sleeve plate 904 and the extension plate 902 upwards. The upper end of the lead screw 901 is then moved upwards. When the operator is still a short distance from the maintenance door 7, they push the extension plate 902. The extension plate 902 moves upwards inside the sleeve plate 904 and moves to the required position. The corresponding reserved slot 903 aligns with the limiting slot on the sleeve plate 904. The operator then inserts the limiting column 909 into the limiting slot and through the corresponding reserved slot 903. The operator then climbs onto the extension plate 902, which has a footrest on the sleeve plate 904. The operator then opens the maintenance door 7 to inspect and repair the interior. This is the working principle of this multi-stage series high-efficiency wind power generation device.
