Description

无标题Untitled 技术领域Technical field
本发明涉及风力发电的技术领域,具体涉及一种可单独或阵列安装在地表或海面上各种有风场所的、以外部导流板组合辅助内部无轴转动轮叶的风力发电装置。The invention relates to the technical field of wind power generation, in particular to a wind power generation device which can be installed separately or in an array on various windy places on the surface or on the sea surface, and which is combined with an external baffle to assist the internal shaftless rotating vanes.
背景技术Background technique
目前,公知的风力发电技术是水平轴叶片风轮机,垂直轴直片式H形、弧片式S形风轮机等,通过风力直接推动叶片运行,流过之风能亦只能作用一次。水平轴风轮叶片垂直于风向运转,其扫掠面积与叶片接收风能之面积比,相对是偏低的,比对垂直轴,叶片垂直于风向水平运转,其工作面积与作用面积之比虽有提升,但水平回转时叶片、连杆因逆风阻力做成部份风能被抵消,而由于两种风轮机转动轮叶都外露,难免对雀鸟做成危害,影响自然生态环境。At present, the well-known wind power generation technology is a horizontal-axis blade wind turbine, a vertical-axis straight-plate type H-shaped, a curved-plate type S-shaped wind turbine, etc., and the wind power directly drives the blade to operate, and the wind energy flowing through it can only be applied once. The horizontal axis wind turbine blade runs perpendicular to the wind direction, and the ratio of the swept area to the area of the blade receiving wind energy is relatively low. Compared with the vertical axis, the blade runs horizontally perpendicular to the wind direction, and the ratio of the working area to the active area is Lifting, but when the horizontal rotation, the blades and connecting rods are partially offset by the wind resistance, and because the rotating blades of both wind turbines are exposed, it is inevitable that the birds will be harmed and affect the natural ecological environment.
参阅图6,现有风力发电装置1包括一端固设于地面的支撑架11、一枢设于该支撑架11另一端的风扇12、及一与该风扇12电连接的发电机组13。该风扇12具有一三片螺旋桨形的扇叶121。Referring to FIG. 6, the conventional wind power generator 1 includes a support frame 11 fixed to the ground at one end, a fan 12 pivoted at the other end of the support frame 11, and a generator set 13 electrically connected to the fan 12. The fan 12 has a three-blade propeller-shaped blade 121.
所述扇叶121因承受风力而转动,而该发电机组13则将所述扇叶121转动时的动能转换为电能,达到以风力发电的功效。然而,现有风力发电装置1整体的体积庞大,并不适合安装于高楼林立的都市中,而且现有风力发电装置1的风扇12无法随风场改变方向,无法随时受不同方向的风力吹拂而转动导致发电效率不稳定。The fan blade 121 rotates due to the wind, and the generator set 13 converts the kinetic energy of the fan blade 121 into electric energy to achieve the effect of generating electricity by wind power. However, the existing wind power generator 1 as a whole is bulky and is not suitable for installation in a city with high-rise buildings, and the fan 12 of the existing wind power generator 1 cannot change direction with the wind field, and cannot be blown by wind in different directions at any time. The rotation causes the power generation efficiency to be unstable.
现有风力发电装置均需要庞大的体积来达到需求风力发电量,由于大体积,影响了风力发电装置的安装场所比较局限,而且难以和都市建筑及居住房并存而不对其周边景观造成破坏或污染。Existing wind power generation devices require a large volume to meet the demand for wind power generation. Due to the large volume, the installation site of the wind power generation device is relatively limited, and it is difficult to coexist with urban buildings and living houses without causing damage or pollution to the surrounding landscape. .
综上所述,现有风力发电装置存在体积庞大、占地面积大、风能可用比率偏低、发电启动要求风力较高、破坏景观、运作产生噪音、伤害周边生态等多种技术限制,以致风力发电难以普及到每家每户,而只能应用在广阔的平原或某些特定的风区,无法广范围应用。现存风力发电设备的製作成本高昂,且维修率高,机体及零件难以回收应用,无法在应用上达到更高效益。本发明突破目前风力发电装置的技术瓶颈,使几乎任何区域都能装设风力发电设备,并且更有效地将地球上的风力资源加以应用。In summary, the existing wind power generation devices have various technical limitations such as large size, large floor space, low wind energy availability ratio, high wind power generation requirements, damage to the landscape, operation noise, and damage to the surrounding ecology. Power generation is difficult to spread to every household, but can only be applied to a wide plain or some specific wind areas, and cannot be widely applied. The existing wind power generation equipment has high production cost and high maintenance rate, and the body and parts are difficult to recycle and can not achieve higher efficiency in application. The invention breaks through the technical bottleneck of the current wind power generation device, enables wind power generation equipment to be installed in almost any area, and more effectively applies the wind resources on the earth.
发明内容Summary of the invention
为了克服现有风力发装置的风能利用率偏低,转动轮叶外露,来流风能只作用一次,及轮叶逆风阻力等问题,本發明提供一种风能转为机械能带动发电机发电的风力发电装置,其转动轮叶是内藏于固定的全向导流板組中间。In order to overcome the problem that the wind energy utilization rate of the existing wind power generation device is low, the rotating wheel is exposed, the wind energy is applied only once, and the blade wind is resistant to wind, the present invention provides a wind power generation device in which wind energy is converted into mechanical energy to drive the generator to generate electricity. The device, whose rotating vanes are built in the middle of a fixed full-guide plate set.
本发明的目的是采用以下的技术方案来实现的。依据本发明所述的风力发电装置其中包含一个以中心点向外辐射安装的漩涡状中空无轴轮叶(107)、一组围绕该轮叶安装的漩涡状导流板组合(104)、一 组作爲该导流板组合支撑的水平隔流板装置(101,102,103)、一个位于中空无轴轮叶的上方的发电单元(105)、一个位于中空无轴轮叶下方的发电单元(106)、数个单独对漩涡状导流板组合内每块导流板进行转向的控制电机(108)、一个根据风速及发电单元电压变化而自协调控制电机转向的集成计算器(109)、数个围绕水平隔流板装置安装的可透风安全栅格装置(110)。The object of the present invention is achieved by the following technical solutions. A wind power generator according to the present invention includes a swirling hollow shaftless vane (107) radiating outwardly from a center point, a set of swirling baffle assemblies (104) mounted around the vane, and a The group is a horizontal baffle device (101, 102, 103) supported by the baffle, a power generating unit (105) located above the hollow shaftless vane, and a power generating unit located below the hollow shaftless vane ( 106) a plurality of control motors (108) that individually steer each baffle in the combination of the vortex baffles, an integrated calculator (109) that automatically controls the steering of the motor according to changes in wind speed and power unit voltage, A plurality of permeable safety grid devices (110) mounted around the horizontal baffle device.
所述的风力发电装置为规则多边形结构,可以多种方式水平及垂直贴合,使之能因应不同环境组合安装;整个装置的外框是由上下两块水平隔流板(101,103)加上垂直支撑条(102)组成。上下水平隔流板四个角落均有便于连结固定的扣件孔道,使两个或多个所述的风力发电装置均可以多点无缝接合,从而因应实际使用情况而变化出不同的组合方式。The wind power generation device has a regular polygonal structure and can be horizontally and vertically fitted in various ways, so that it can be assembled according to different environments; the outer frame of the whole device is composed of two upper and lower horizontal baffles (101, 103) plus vertical The support bar (102) is composed. The four corners of the upper and lower horizontal baffles have fastening holes that are easy to be connected and fixed, so that two or more of the wind power generating devices can be seamlessly joined at different points, thereby changing different combinations according to actual use conditions. .
所述风力发电装置可以固定比例制作不同大小,并以固定比例增加相应数量的扣件孔道,故此即使是不同大小的风力发电装置,也能自由组合安装。所述风力发电装置自由组合阵列后,可以布置于各种现存风力发电装置难以有效使用的场所,充分利用各大小风区的风能。The wind power generation device can be manufactured in different proportions in a fixed ratio, and the corresponding number of fastener holes can be increased in a fixed ratio, so that even wind turbines of different sizes can be freely assembled and installed. After the wind power generation device is freely combined with the array, it can be arranged in a place where various existing wind power generation devices are difficult to use effectively, and the wind energy of each size wind region can be fully utilized.
所述风力发电装置使用规则多边形制作,故此相对现存多种以垂直轴安装的风力发电装置,本发明提及的风力发电装置更能稳定地安装在各种地表及建筑物上,也可以倒悬在建筑物悬空处、或固定于建筑物的外墙上。The wind power generation device is manufactured using a regular polygon, so that the wind power generation device installed in the present invention is more stably installed on various ground surfaces and buildings than the existing wind power generation device installed on the vertical axis, and can also be hung upside down. The building is suspended or fixed to the outer wall of the building.
所述的风力发电装置包含安全栅格装置(110),安全栅格能阻止风力发电装置运作期间将伴随来流的异物或生物隔绝在风力发电装置之外,避免风力发电装置运作时对周边生物造成伤害,同时在不对风力发电装置效能造成重大影响的情况下,将可能导致风力发电装置运作受阻的异物排除在装置之外,一定程度上保证了所述风力发电装置的运作稳定性。The wind power generation device comprises a safety grid device (110), which can prevent foreign matter or organisms accompanying the incoming flow from being isolated from the wind power generation device during operation of the wind power generation device, and avoid the surrounding living organisms when the wind power generation device operates The damage is caused, and the foreign matter that may hinder the operation of the wind power generation device is excluded from the device without any significant influence on the performance of the wind power generation device, and the operational stability of the wind power generation device is ensured to some extent.
所述风力发电装置的漩涡状导流板组合(104),作用将其所处水平上任何进入的来流均能被引导往风力发电装置的内腔,进而驱动漩涡状导流板组合内的中空无轴轮叶(107)转动而发电。漩涡状导流板组合的设计使风力发电装置无需通过任何变形或移动追踪来流,也无需因为来流风向改变而切换导流板的角度。The vortex baffle assembly (104) of the wind power generator can direct any incoming flow at the level of the wind power generating device to the inner cavity of the wind power generating device, thereby driving the vortex baffle assembly The hollow shaftless vane (107) rotates to generate electricity. The design of the swirling baffle combination allows the wind power plant to flow without any deformation or movement tracking, nor the angle of the baffle to be switched due to the changing wind direction.
所述风力发电装置的漩涡状导流板组合(104),其每片导流板均从装置中心朝外辐射等距安装,装置导流板数量为3块或以上。每块导流板按照自组合的中心以顺时针或逆时针的漩涡状弯曲,组合后的漩涡状导流板组合成中空漩涡状构造,使多方向来流往中心空间集中。并有利于来流在所述风力发电装置内腔形成涡流,辅助带动中心的中空无轴轮叶转动。The vortex baffle assembly (104) of the wind power generator device is each equidistantly mounted from the center of the device to the outside of the device, and the number of the device baffles is three or more. Each baffle is curved in a clockwise or counterclockwise spiral according to the center of the self-combination, and the combined swirling baffles are combined into a hollow spiral structure to concentrate the multi-directional flow to the central space. Moreover, it is advantageous for the incoming flow to form a vortex in the inner cavity of the wind power generating device, and to assist the rotation of the hollow shaftless vane of the center.
基于所述风力发电装置的漩涡状导流板组合的中空漩涡状构造,在已知方向的来流下,来流上游处即漩涡状导流板组合的外部断面积往其中心内腔处渐小,来流在此部分被增压加速流向内腔;当来流通过漩涡状导流板组合并驱动内腔的中空无轴轮叶后,来流流向下游部分,此处的漩涡状导流板组合的断面积往下游更远处渐大,因而能形成负压区,牵引来流流出风力发电装置。 Based on the hollow vortex structure of the vortex baffle combination of the wind power generation device, the outer cross-sectional area of the vortex baffle assembly is gradually reduced toward the center cavity at the upstream of the flow in the known direction. The incoming flow is supercharged and accelerated to the inner cavity in this part; when the incoming flow is combined by the swirling baffle and drives the hollow shaftless vane of the inner cavity, the flow flows to the downstream part, where the swirling baffle The combined sectional area is gradually enlarged further downstream, so that a negative pressure zone can be formed, and the traction flows out of the wind power generation device.
基于所述风力发电装置的漩涡状导流板组合的中空漩涡状构造,在已知方向的来流下,当来流驱动中空无轴轮叶转动时,可以将能对中空无轴轮叶产生逆风阻力的来流屏蔽或导引到中空无轴轮叶轮叶的凹位处,从而有利中空无轴轮叶转动并防止来流对中空无轴轮叶的转动产生逆风阻力。Based on the hollow vortex structure of the vortex baffle combination of the wind power generation device, when the flow of the hollow shaftless wheel is rotated under the flow of the known direction, the wind can be generated against the hollow shaftless blade The inflow of the resistance is shielded or guided to the concave position of the hollow shaftless wheel impeller blade, thereby facilitating the rotation of the hollow shaftless vane and preventing the incoming flow from generating an upwind resistance to the rotation of the hollow shaftless vane.
所述的风力发电装置中的中空无轴轮叶及上下发电单元,其特征为:中空无轴轮叶(107)夹於位于其上方的发电单元(105)及其下方的发电单元(106)中间,三者构成一体。中空无轴轮叶上方的发电单元(105)的底盘从垂直高度较低的中心向垂直高度较高的边缘呈放射状倾斜,位于中空无轴轮叶下方的发电单元(106)的顶盘从垂直高度较高的中心向垂直高度较低的边缘呈放射状倾斜,形成上下发电单元及中空无轴轮叶内空间成沙漏状,使中心的中空无轴轮叶内部不容易积存异物。该沙漏状设计可以使中空无轴轮叶上部不容易冻结出冰柱,使其下部不容易积存砂石或小型异物,更大程度提升风力发电装置运作的稳定性和效能。The hollow shaftless vane and the upper and lower power generating unit in the wind power generator are characterized in that the hollow shaftless vane (107) is sandwiched between the power generating unit (105) located above and the power generating unit (106) located therebelow In the middle, the three are integrated. The chassis of the power generating unit (105) above the hollow shaftless vane is radially inclined from the center of the lower vertical height to the edge of the higher vertical height, and the top plate of the power generating unit (106) located below the hollow shaftless vane is vertical The center of the higher height is radially inclined toward the edge with a lower vertical height, and the inner space of the upper and lower power generating unit and the hollow shaftless wheel is formed into an hourglass shape, so that the inside of the hollow hollow shaft of the center is less likely to accumulate foreign matter. The hourglass-like design makes it difficult for the upper part of the hollow shaftless bucket to freeze the icicles, so that the sandstone or small foreign matter is not easily accumulated in the lower part, and the stability and efficiency of the operation of the wind power generation device are enhanced to a greater extent.
所述的风力发电装置中的上下发电单元,内部含多个永磁块,以圆周排列;上下发电单元嵌套于上下隔流板装置中,上下隔流板与上下发电单元的接合处具有多组发电轮圈,以圆周排列,每双数个轮圈为一组,全部连接到集成计算器中。上下发电单元均有一个插接于其接合之隔流板装置的支撑轴,支撑轴接合上下隔流板的位置有转速感应件,将转速传到集成计算器。当所述风力发电装置处于无风状态时,发电单元无工作,故无转速,集成计算器感应到无转速或低于最低启动所需转速时,发电轮圈处于关闭状态,使中空无轴轮叶轮叶及发电单元处于无荷载状态。当中空无轴轮叶轮叶及发电单元转速达到额定要求时,集成计算器获取信号,开始开启相应数量的发电轮圈,使风力发电装置开始发电。随着风速增强至不同程度,中空无轴轮叶轮叶及发电单元的转速也会有不同变化,集成计算器监测该变化而启动相应数量的发电轮圈至满负载为止。The upper and lower power generating units in the wind power generator include a plurality of permanent magnet blocks and are arranged in a circle; the upper and lower power generating units are nested in the upper and lower baffle devices, and the upper and lower baffles are connected to the upper and lower power generating units. The group of generator wheels is arranged in a circle, each pair of wheels is a group, all connected to the integrated calculator. The upper and lower power generating units each have a support shaft that is inserted into the joined baffle device. The support shaft engages the upper and lower baffles at a position with a rotational speed sensing member to transmit the rotational speed to the integrated calculator. When the wind power generation device is in a windless state, the power generation unit has no work, so there is no rotation speed, and the integrated calculator senses that there is no rotation speed or lower than the minimum required rotation speed, the power generation rim is closed, and the hollow shaftless wheel The impeller blades and the power generating unit are in an unloaded state. When the speed of the hollow shaftless impeller blade and the power generating unit reaches the rated requirement, the integrated calculator acquires the signal and starts to turn on the corresponding number of power generating rims to start the wind power generation device to generate electricity. As the wind speed increases to different degrees, the rotational speed of the hollow shaftless impeller blades and the power generating unit will also vary, and the integrated calculator monitors the change and activates the corresponding number of generating rims to full load.

具体实施方式detailed description
本发明所述的风力发电装置,可单独工作或串联工作。The wind power generation device of the present invention can work alone or in series.
参考图4,在已知方向的来流下,本发明所述的风力发电装置单独工作时,来流经过可透风安全 栅格装置(110)将伴随来流的异物或生物隔绝在风力发电装置之外,来流进入水平隔流板装置C区时(101,102,103),该装置产生第一道导流作用,避免来流往风力发电装置的上下方扩散;来流进入漩涡状导流板组合(104)的导流板后,从上游往内腔增压及加速,同时在来流下游即A区的空间形成负压;加速后的来流驱动中空无轴轮叶(107)顺风一边转动,转动时驱动中空无轴轮叶上下两个发电单元发电;来流驱动中空无轴轮叶发电后,穿过该轮叶的中空空间进入下游转动轮叶,实现二次驱动,其后进入下游的漩涡状导流板,受下游导流板内负压区牵引后流出风力发电装置。Referring to FIG. 4, under the inflow of the known direction, the wind power generator of the present invention flows through the permeable air when working alone. The grid device (110) isolates the foreign matter or organism accompanying the incoming flow from the wind power generation device to flow into the horizontal partition plate device C region (101, 102, 103), and the device generates the first guiding effect to avoid the incoming flow. Diffusion into the upper and lower parts of the wind power generator; after flowing into the deflector of the swirling baffle assembly (104), it is pressurized and accelerated from the upstream to the inner chamber, and a negative pressure is formed in the space downstream of the incoming flow, that is, in the space A. After the acceleration, the hollow shaftless vane (107) is driven to rotate along the wind, and the upper and lower power generating units of the hollow shaftless vane are driven to generate electricity when rotating; and the hollow shaftless vane is driven to generate electricity, and then passes through the vane. The hollow space enters the downstream rotating vane to realize secondary driving, and then enters the downstream swirling baffle, which is pulled by the negative pressure zone in the downstream deflector and then flows out of the wind power generating device.
参考图4,在已知方向的来流下,当来流进入水平隔流板装置(101,102,103)及漩涡状导流板组合(104)的B区时,部分来流会被屏蔽而无法经过漩涡状导流板组合进入其内腔中的中空无轴轮叶,而部分来流则经过漩涡状导流板组合的折射后增压流入其内腔处,作为辅助驱动中空无轴轮叶的动力。Referring to Fig. 4, under the inflow of the known direction, when the incoming flow enters the horizontal baffle device (101, 102, 103) and the B-zone of the swirling baffle assembly (104), part of the incoming flow is shielded and cannot be vortexed. The deflector combines into the hollow shaftless vanes in its inner cavity, and part of the flow is condensed by the swirling baffle combination and then pressurized into the inner cavity as a driving force for driving the hollow shaftless vanes.
参考图4,在已知方向的来流下,当来流进入水平隔流板装置(101,102,103)及漩涡状导流板组合(104)的D区时,来流会漩涡状导流板组合的折射后增压流入其内腔处,作为辅助驱动中空无轴轮叶的动力。换言之,整个风力发电装置任何迎风一面的表面积当中,都有多于一半至四分三的部分能吸收来流风能。Referring to Fig. 4, under the inflow of the known direction, when the flow enters the horizontal baffle device (101, 102, 103) and the D-zone of the swirling baffle assembly (104), the refraction of the swirling baffle combination is flowed. The post-pressurization flows into its inner cavity as a power to assist in driving the hollow shaftless vanes. In other words, more than half to three-quarters of the surface area of any windward side of the entire wind power plant can absorb wind energy.
参考图4,在已知方向的来流下,当来流打到中空无轴轮叶的轮叶凹位处(或顺风一边)时,推动轮叶后的来流一部分会随着推送中空无轴轮叶转动后从A区直接流出,一部分则会在推动轮叶时散射到中空无轴轮叶的中空部分即D区,散射到D区的来流因中空无轴轮叶轮叶的中空设计,故可以穿过中控区域D到达中空无轴轮叶的来流下游处,从而对中空无轴轮叶实施二次驱动。小部分来流会会同B区和D区的来流散射,在中空无轴轮叶的中空部分形成涡流,加强牵扯来流自上流进入及逃入下流。Referring to Fig. 4, under the inflow of the known direction, when the flow is hit to the concave groove of the hollow shaftless vane (or on the side of the wind), a part of the incoming flow behind the impeller is pushed with the hollow shaft. After the vane rotates, it flows out directly from the A zone, and a part of it scatters to the hollow part of the hollow shaftless vane, that is, the D zone when the vane is pushed, and the flow scattered to the D zone is hollowed by the hollow design of the hollow shaftless impeller blade. Therefore, it is possible to pass through the central control region D to the downstream of the inflow of the hollow shaftless vane, thereby performing secondary driving on the hollow shaftless vane. A small part of the flow will be scattered with the incoming flow of the B zone and the D zone, forming a vortex in the hollow part of the hollow shaftless vane, and strengthening the pulling flow from the upper flow into and from the downstream.
参考图1,当所述风力发电装置单独运作时,其所有垂直外部立面均可以装配可透风安全栅格装置,以抵挡外来异物。当所述风力发电装置阵列运作时,各装置的接合面上的可透风安全栅格装置可以拆卸,从而更有利来流通过,并降低阵列安装时整批风力发电装置的安装及购买成本。Referring to Figure 1, when the wind power generator is operated alone, all of its vertical outer façades can be fitted with permeable safety grid means to withstand foreign objects. When the array of wind power generators is operated, the permeable safety grid device on the joint surface of each device can be disassembled, thereby facilitating the flow and reducing the installation and purchase cost of the entire batch of wind power generation devices during the array installation.

When the speed of the hollow shaftless impeller blade and the power generating unit reaches the rated requirement, the integrated calculator acquires the signal and starts to turn on the corresponding number of power generating rims to start the wind power generation device to generate electricity. As the wind speed increases to different degrees, the rotational speed of the hollow shaftless impeller blades and the power generating unit will also vary, and the integrated calculator monitors the change and activates the corresponding number of generating rims to full load.

According to the integrated calculator command, the swirling baffle is gradually twisted and turned uniformly to narrow the spiral shape. The wind inlet angle of the baffle combination regulates the wind speed entering the wind power generator until the speed of the power generating unit and the output voltage return to an acceptable level, otherwise the swirling baffle will be twisted until it is completely closed.
