Description

Technical Field

[0001] The invention relates to the field of wind power generation, and in particular to an intelligently regulated environmentally friendly wind power generator. Background Art

[0002] As a new energy product, wind turbines use wind power to drive the rotation of blades, generate electricity by cutting magnetic field lines, and then store the electricity through energy storage devices. However, since the blades are initially designed to withstand wind forces within a certain range, when encountering stronger wind forces, the blades cannot withstand the force and are prone to breakage, which in turn causes the device to be damaged and unable to work normally. The existing method of adding a reinforced structure to the blades tends to make the blades heavier, resulting in poor power generation effect of the blades. Others protect the blades by shielding them. When used as a wind turbine, when encountering stronger wind forces, the blades are protected by shields. However, wind power cannot be used to continue to generate electricity during protection, which limits the use of this method.

[0003] At the same time, when the blades are rotating for a long time to generate electricity, impurities such as dust in the air tend to adhere to the surface of the blades. The adhesion of dust will cause the mass distribution of the blades to become uneven, resulting in additional vibration during rotation, shortening the service life of the blades. Dust accumulation will change the roughness of the blade surface, increase wind resistance, and thus reduce the aerodynamic efficiency of the wind turbine. Summary of the invention

[0004] In order to overcome the limitations of using a cover to protect the blades when encountering strong winds and being unable to utilize strong winds for power generation, and the defects of adding a reinforcement structure to the blades that easily makes the blades heavy and difficult to rotate, and the long-term rotation of the blades easily adheres to dust in the air, resulting in a shortened blade life and poor power generation effect, the present invention provides an intelligently adjustable environmentally friendly wind turbine.

[0006] In addition, it is particularly preferred that a roller is further included; each second reinforcing rib is rotatably connected to a roller for cleaning the blades.

[0007] In addition, it is particularly preferred that a baffle is further included; the rotating part on the fixed rod is fixedly connected to two baffles for preventing the blades from icing.

[0008] In addition, it is particularly preferred that it also includes a shield and a filter; a shield for collecting rainwater is rotatably connected to the upper side of the fixed rod; the side of the shield is fixedly connected to the upper side of the protective cover; the lower side of the shield is fixedly connected to the second reinforcement rib; three drain outlets are opened on the shield; a filter is fixedly connected to each drain outlet; a guide groove is opened in each second reinforcement rib; and each drain outlet is connected to the adjacent guide groove.

[0009] In addition, it is particularly preferred that it also includes a connecting column and a brush strip; a connecting column is fixedly connected to the upper side of the fixing rod; and a brush strip is fixedly connected to the connecting column to prevent impurities from clogging the filter screen.

[0010] In addition, it is particularly preferred that it also includes an electric push rod, an air induced cloth and an electric slider; three electric push rods are fixedly connected to the fixed rod; the telescopic end of each electric push rod is fixedly connected to the adjacent blade; a number of air induced cloths that drive the protective cover to rotate are fixedly connected to the outer surface of the protective cover, and the air induced cloth is made of windproof cloth; three electric sliders are fixedly connected to the lower side of the protective cover; each electric slider slides on the adjacent second reinforcement rib.

[0011] Furthermore, it is particularly preferred that the mask is configured in a conical shape.

[0012] In addition, it is particularly preferred that the roller is made of sponge material, and the diameter of the roller is greater than the width of the guide groove.

[0013] In addition, it is particularly preferred that a plurality of guide grooves are provided on the shield.

[0014] In addition, it is particularly preferred that a rotating rod is further included; the rotating portion of the fixed rod is rotatably connected to two rotating rods through a torsion spring to prevent the baffle from interfering with the rotation of the blades; each rotating rod is fixedly connected to the adjacent baffle.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes that the blades are shielded by the protective cover to resist the environment with strong wind force, thereby protecting the blades and preventing the strong wind from directly acting on the blades, ensuring that the device is not damaged, and improving the adaptability of the device;

[0016] The blades are extended by the electric push rod so that the blades contact the side of the second reinforcing rib, thereby driving the blades to rotate counterclockwise to generate electricity, thereby driving the blades to rotate and generate electricity while protecting the blades, thereby improving the stable power generation capacity of the device in extreme weather conditions;

[0019] The blades are completely sealed by cooperating with the baffle plate on the lower side of the protective cover, so that moisture in the air cannot directly adhere to the blades. When a large amount of ice cubes adhere to the surface of the protective cover, the ice cubes on the surface of the protective cover are crushed during the process of storing the protective cover, thereby avoiding the weight increase of the protective cover itself due to ice formation and improving the adaptability of the device.

[0020] The torsion spring on the rotating rod drives the baffle to rotate downward, so that the baffle gradually moves away from the lower side of the blade, so that the rotated baffle cannot carry large impurities such as branches in a parallel state, thereby ensuring the normal operation of the blade.

[0032] A roller 110 is also included; each second reinforcing rib 107 is rotatably connected to a roller 110 .

[0033] It also includes baffles 4; the rotating part 1001 on the fixed rod 1 is fixedly connected to two baffles 4.

[0034] It also includes a mask 102 and a filter 109; the mask 102 is rotatably connected to the upper side of the fixed rod 1; the side of the mask 102 is fixedly connected to the upper side of the protective cover 3; the lower side of the mask 102 is fixedly connected to the second reinforcement rib 107; three drain outlets 10201 are opened on the mask 102; a filter 109 is fixedly connected to each drain outlet 10201; a guide groove 10701 is opened in each second reinforcement rib 107; each drain outlet 10201 is connected to the adjacent guide groove 10701.

[0035] It also includes a connecting column 103 and a brush strip 104 ; a connecting column 103 is fixedly connected to the upper side of the fixing rod 1 ; a brush strip 104 is fixedly connected to the connecting column 103 .

[0036] It also includes an electric push rod 101, an air induced cloth 105 and an electric slider 108; three electric push rods 101 are fixedly connected to the fixed rod 1; the telescopic end of each electric push rod 101 is fixedly connected to the adjacent blade 2; a plurality of air induced cloths 105 are fixedly connected to the outer surface of the protective cover 3, and the air induced cloth 105 is made of windproof cloth; three electric sliders 108 are fixedly connected to the lower side of the protective cover 3; each electric slider 108 slides on the adjacent second reinforcement rib 107.

[0037] The shield 102 is configured to be conical, so as to guide rainwater to flow toward the side of the shield 102 and collect and utilize the rainwater.

[0038] The roller 110 is made of sponge material, and the diameter of the roller 110 is larger than the width of the guide groove 10701, so as to absorb rainwater to clean the blades 2. At the same time, the guide groove 10701 is used to squeeze the roller 110 to squeeze out the cleaned sewage.

[0039] A plurality of guide grooves 10701 are provided on the cover 102 to facilitate guiding rainwater to flow into the guide grooves 10701 .

[0040] When workers install the fixing rod 1 on the ground, the blades 2 are rotated in a windy environment, so that the power generation structure connected to the blades 2 generates electricity. During the power generation, since the blades 2 are initially designed to withstand limited wind force, when encountering strong wind force, the blades 2 are prone to breakage when their bearing capacity cannot withstand it. In order to avoid this phenomenon, when encountering strong wind force, the electric slider 108 is started to slide downward on the second reinforcing rib 107, thereby driving the protective cover 3 to unfold downward. Figure 2 As shown, at this time, the protective cover 3 is supported by the unfolded first reinforcing ribs 106 and the second reinforcing ribs 107, so that the protective cover 3 covers the blades 2 102 to resist strong winds, thereby protecting the blades 2 and preventing strong winds from directly acting on the blades 2, ensuring that the device is not damaged and improving the adaptability of the device.

[0041] In the process of protecting the blade 2, in order to ensure the power generation effect of the wind turbine, in the case of strong wind, the electric push rod 101 is started to extend in the direction away from the fixed rod 1, and then the blade 2 is extended. At this time, the blade 2 contacts the side of the second reinforcing rib 107. When the wind acts on the air-inducing cloth 105, the air-inducing cloth 105 is affected by the wind and drives the protective cover 3 to rotate counterclockwise, and because the rotating part 1001 can rotate on the fixed rod 1, the rotating part 1001 rotates counterclockwise synchronously, thereby driving the first reinforcing rib 106 and the second reinforcing rib 107 to rotate. The reinforcing rib 107 rotates counterclockwise synchronously, thereby driving the blade 2 to rotate counterclockwise to generate electricity, and driving the blade 2 to rotate to generate electricity while protecting the blade 2, thereby improving the stable power generation capacity of the device under extreme weather conditions. When the speed of the protective cover 3 driven by the wind exceeds the tolerable range of the blade 2, the electric push rod 101 is started to contract, thereby driving the blade 2 back to the initial state and separating from the second reinforcing rib 107, and then only utilizing the rotation of the protective cover 3 to prevent the wind from blowing directly to the protective cover 3, thereby reducing the impact on the device under strong winds and protecting the blade 2 in the protective cover 3.

[0042] It is also considered that when the blade 2 rotates for a long time to generate electricity, the dust and other impurities in the air are easily adhered to the surface of the blade 2, and the accumulation of dust will change the roughness of the surface of the blade 2, increase the wind resistance, and thus reduce the aerodynamic efficiency of the wind turbine. In order to avoid this phenomenon, by starting the electric push rod 101 to contract, the blade 2 is driven to contract, so that the blade 2 is away from the second reinforcing rib 107. At this time, the protective cover 3 continues to rotate under the action of the induced draft cloth 105, thereby driving the second reinforcing rib 107 to rotate, so that the roller 110 on the second reinforcing rib 107 contacts the surface of the blade 2, and then the roller 110 is used to scrape off the dust adhering to the surface of the blade 2, so that the windward side of the blade 2 is kept clean, thereby improving The power generation capacity of the device is improved, and the service life of the device is extended. The side of the drum 110 is in contact with the guide groove 10701, so that the drum 110 is scraped by the side of the guide groove 10701 when it rotates, so that the dust attached to the drum 110 is scraped off and falls on the baffle 4. When the blade 2 rotates for a long time to generate electricity, the dust on the blade 2 can be cleaned for daily maintenance in the above manner to avoid the blade 2 from accumulating too much dust and failing to work normally. At the same time, the problem of high difficulty in maintaining the blade 2 by workers can be solved. After the dust is scraped off, the electric slider 108 is started to slide upward, and the protective cover 3 is retracted, and the dust dropped on the baffle 4 is discharged by the wind.

[0043] During the process of the drum 110 cleaning the blades 2, in order to further improve the cleaning effect of the blades 2, the cover 102 is used to collect rainwater when it rains, so that the rainwater flows along the upper side of the cover 102 to the drain port 10201. At this time, the filter 109 is used to intercept impurities in the rainwater, so that the clean rainwater flows through the filter 109 to the guide groove 10701, and then the guide groove 10701 accumulates clean rainwater. Since the drum 110 is made of sponge material, the drum 110 can clean the blades 2 after absorbing water, thereby improving the cleaning effect of the blades 2. At the same time, since the diameter of the drum 110 is greater than the width of the guide groove 10701, when the drum 110 rotates due to the friction force with the blades 2, the contact position of the drum 110 and the guide groove 10701 is The dust and rainwater adsorbed by the roller 110 are squeezed and then squeezed while the roller 110 rotates, so that the dust and rainwater are squeezed out and discharged to the baffle 4, and finally collected by the protective cover 3 and discharged under the influence of wind. In this process, considering that the filter 109 is easily blocked by rainwater or impurities mixed in the air, when the induced draft cloth 105 drives the protective cover 3 to rotate, the protective cover 3 also synchronously drives the mask 102 to rotate. With the top-down view as the reference, relative to the connecting column 103 and the brush bar 104, the mask 102 drives the filter 109 to rotate counterclockwise. When the filter 109 passes through the brush bar 104, the brush bar 104 is used to brush off and clean the impurities intercepted on the filter 109, so that the rainwater can penetrate the filter 109 into the guide groove 10701, and the supply roller 110 cleans the blades 2.

[0044] It is also taken into consideration that when encountering cold weather, the moisture in the air at night is easy to freeze on the surface of the blade 2, making it difficult for the blade 2 to rotate when it freezes at night. In order to avoid this phenomenon, when the protective cover 3 is unfolded, the lower side of the protective cover 3 cooperates with the baffle 4 to completely seal the blade 2, so that the moisture in the air cannot directly adhere to the blade 2 through the protective cover 3 and the baffle 4. The electric push rod 101 is extended and drives the blade 2 to extend, so that the second reinforcement rib 107 drives the blade 2 to generate electricity at night. When the surface of the protective cover 3 is covered with ice, the ice on the surface of the protective cover 3 is crushed by the process of storing the protective cover 3, and then the protective cover 3 is unfolded again to avoid the weight gain of the protective cover 3 itself due to ice, thereby improving the adaptability of the device.

[0045] Example 2

[0046] On the basis of Example 1, Figure 1 , Figure 5 and Figure 6 As shown, a rotating rod 201 is also included; two rotating rods 201 are rotatably connected to the rotating portion 1001 of the fixed rod 1 through a torsion spring; each rotating rod 201 is fixedly connected to the adjacent baffle 4.

[0047] When the blade 2 is protected by the protective cover 3 and the baffle 4, it is considered that the baffle 4 is always under the blade 2 after the protective cover 3 is stored. When the external airflow carries large impurities such as branches and blows towards the baffle 4, the branches and other large impurities are easily blocked by the baffle 4 and the fixing rod 1. When impurities such as branches remain on the baffle 4, they are easy to touch the blade 2, thereby affecting the normal rotation of the blade 2. In order to avoid this phenomenon, when the electric slider 108 drives the protective cover 3 to be stored upward, the torsion spring on the rotating rod 201 loses the squeezing restriction of the electric slider 108, and the baffle 4 on the left side rotates counterclockwise and the baffle 4 on the right side rotates clockwise based on the view from the front to the back, thereby causing the two baffles 4 to rotate downward as shown in FIG. Figure 6 As shown, the baffle 4 is gradually moved away from the lower side of the blade 2, so that the baffle 4 after rotation cannot bear the branches in a parallel state, ensuring the normal operation of the blade 2. When the electric slider 108 slides downward, the electric slider 108 pushes the raised baffle 4 to rotate back to the position shown in FIG. Figure 5 In the state shown, the protective cover 3 and the baffle 4 cooperate to reseal and protect the blade 2.
