Description

Technical Field

[0001] This invention relates to the field of new energy technology, specifically to a wind-solar hybrid power generation device. Background Technology

[0002] Wind-solar hybrid power generation refers to a new energy power generation device that combines wind power generation with solar power generation. Wind power generates electricity at night and on cloudy days when there is no sunlight, while solar power generates electricity on sunny days. Both power sources work simultaneously when there is both wind and sunlight, achieving all-weather power generation. This is more economical, scientific, and practical than using wind turbines and solar energy alone. While wind-solar hybrid power generation devices can achieve complementary utilization of solar and wind energy, the photovoltaic panels, which convert solar energy, are easily affected by external interference. When covered with dust, snow, or other foreign objects, the power generation efficiency of the photovoltaic panels is greatly affected, leading to reliance solely on wind power for power generation and resulting in low overall efficiency.

[0003] A search revealed that CN219227464U discloses a wind-solar hybrid power generation device. This device includes a base, with a platform fixedly connected to the upper end of the base. An adjustment component is fixedly installed on the upper end of the platform, and a photovoltaic power generation component is fixedly installed on the upper end of the adjustment component. A pair of wind power generation components are also fixedly installed on the upper end of the platform, with the wind power generation components evenly distributed around the photovoltaic power generation components. A rotating seat is installed on the upper end of each wind power generation component, and multiple evenly distributed blades are fixedly installed on the outer end of the rotating seat. A cleaning component is installed on the rotating seat. This device can achieve secondary utilization of wind energy by setting up the cleaning component, and based on the rotational motion, it can periodically clean the surface of the photovoltaic power generation components, enabling them to generate electricity at consistently high efficiency.

[0004] However, the aforementioned wind-solar complementary power generation device still has the following problems: the cleaning component of the aforementioned wind-solar complementary power generation device always rotates along with the wind power generation component. Therefore, when cleaning is not required, the rotation of the cleaning component will consume the kinetic energy of the wind power generation component, thereby affecting the conversion of this kinetic energy into electrical energy and causing a certain amount of energy waste. At the same time, due to the friction loss between the cleaning component and the air when it rotates continuously, the service life is short, affecting the cleaning effect. Summary of the Invention

[0005] This invention proposes a wind-solar hybrid power generation device, which solves the problems of kinetic energy loss and self-loss caused by the rotation of the cleaning components in the prior art.

[0006] The technical solution of the present invention is as follows: A wind-solar hybrid power generation device includes a supporting pole and an mounting platform fixed to the top of the supporting pole. The mounting platform is equipped with photovoltaic panels and an adjustment device for adjusting the deflection angle of the photovoltaic panels. Wind turbine shafts and wind blades that drive the wind turbine shafts to rotate under wind power are symmetrically arranged on both sides of the top of the mounting platform. Energy recovery devices are arranged on both sides of the bottom of the mounting platform. A cleaning mechanism is provided on the wind turbine shafts. The cleaning mechanism includes:

[0007] Guide sleeve, fixed to the top surface of the mounting platform;

[0008] The elastic pressure element is installed inside the guide sleeve;

[0009] The sliding component is sleeved on the wind-driven shaft and selectively slides up and down under the drive of the elastic pressure element;

[0010] The wiping component is hinged to one side of the sliding component;

[0011] A flexible reset component elastically connects the sliding component and the wiping component;

[0012] The shock-absorbing component, together with the elastic reset component, stops the wiping component in place;

[0013] The photovoltaic panel has symmetrically arranged blocking components on both sides to block the wiping assembly.

[0014] Preferably, the wind-driven shaft passes through the guide sleeve and is rotatably connected to the mounting platform. The part of the wind-driven shaft located inside the guide sleeve is provided with a stepped groove, and the bottom of the stepped groove is provided with a first protrusion distributed in a ring around the wind-driven shaft.

[0015] Preferably, the elastic pressure member includes a fixed ring and a sliding ring. The fixed ring is fixed inside the guide sleeve, and the sliding ring is slidably disposed between the guide sleeve and the cavity of the pneumatic shaft. An electromagnet is fixed on the opposite side of both the fixed ring and the sliding ring, and the two electromagnets are elastically connected by a first spring.

[0016] Preferably, the sliding assembly includes a sliding sleeve, which is sleeved on the pneumatic shaft at the location of the stepped groove. A fixing rod is fixed on the side wall of the sliding sleeve, and a limiting disk rotatably disposed in the sliding ring is fixed at the bottom of the sliding sleeve. The bottom surface of the limiting disk is provided with a second protrusion that matches the first protrusion.

[0017] Preferably, the wiping assembly includes a brush holder hinged to the end of a fixed rod, and a flexible brush is fixed to the bottom of the brush holder.

[0018] Preferably, the elastic reset member includes a first bracket, a second spring, and a second bracket. The first bracket is fixed to the side of the fixing rod, the second bracket is fixed to the side of the brush holder, and spring rods are fixed to the inner sides of the ends of the first bracket and the second bracket. The two ends of the second spring are respectively fixed to the spring rods of the first bracket and the second bracket.

[0019] Preferably, the shock-absorbing assembly includes a support rod, one end of which is fixed to a fixed rod, and the other end of which is fixed to a stop rod. The brush seat rests against the stop rod under the elastic force of a second spring.

[0020] Preferably, the blocking member includes a fixing plate, which is fixed to the side of the photovoltaic panel. A fixing shaft is fixed to the end of the fixing plate, a roller is rotatably connected to the top of the fixing shaft, and a lever is fixed to the side wall of the fixing shaft.

[0021] Preferably, the fixing rod of the left cleaning mechanism is located directly below the projection of the second protrusion, and the fixing rod of the right cleaning mechanism is located directly below the projection of the midpoint of the two adjacent second protrusions.

[0022] Preferably, after the second protrusion of the cleaning mechanism engages with the first protrusion, the roller is positioned at the height of the brush holder, while the paddle is positioned at the height of the flexible brush.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. In this invention, when the second protrusion on the bottom surface of the limiting disc engages with the first protrusion of the pneumatic shaft, the height position of the brush holder corresponds to the roller of the blocking component, and the height position of the flexible brush corresponds to the lever of the blocking component. Therefore, when the brush holder rotates to contact the roller, it is blocked by the roller and rotates backward due to the elastic force of the second spring on the fixed rod. During this process, the lever continuously scrapes the flexible brush from one end of the brush holder to the other end, cleaning the foreign matter attached to the flexible brush. As the fixed rod continues to rotate, the brush holder disengages from the roller, and the brush holder rebounds rapidly under the elastic force of the second spring. That is, the rotation speed of the brush holder increases until it collides with the stop rod of the shock-absorbing component, which helps to knock off the dust on the flexible brush and maintain the cleaning ability of the flexible brush on the photovoltaic panel. Compared with the prior art, this invention only causes the brush holder and the flexible brush to rotate in the cleaning state, which reduces wear and extends service life.

[0025] 2. In this invention, by de-energizing the electromagnets on the fixed ring and the sliding ring, the sliding ring can lift the wiping component upward under the elastic force of the first spring, causing the flexible brush to leave the surface of the photovoltaic panel, thus avoiding affecting the angle adjustment of the photovoltaic panel. At the same time, the sliding component, along with the wiping component, gradually rises to the second protrusion on the bottom surface of the limiting plate and disengages from the first protrusion of the wind shaft. That is, when the wind shaft rotates, the wiping component will not rotate with the wind shaft, thereby reducing the kinetic energy loss of the wind shaft rotation, facilitating the conversion of kinetic energy into electrical energy, and improving utilization efficiency. Compared with the prior art, this invention solves the problem of kinetic energy loss and self-loss caused by the rotation of the cleaning component in the prior art.

[0026] 3. In this invention, the fixing rod of the left cleaning mechanism is located directly below the projection of the second protrusion, and the fixing rod of the right cleaning mechanism is located directly below the projection of the midpoint of two adjacent second protrusions. This allows the wiping components of the two cleaning mechanisms to automatically stagger when the second protrusion on the bottom surface of the limiting plate of the left and right cleaning mechanisms engages with the first protrusion of the pneumatic shaft, thus avoiding motion interference when the wiping components rotate. Compared with the prior art, the cleaning coverage area of ​​this invention can be designed to be large, avoiding cleaning dead corners. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 and Figure 2 This invention provides a technical solution: a wind-solar hybrid power generation device, including a support pole 1 and an mounting platform 2 fixed to the top of the support pole 1. The mounting platform 2 is equipped with photovoltaic panels 3 and an adjustment device 4 for adjusting the deflection angle of the photovoltaic panels 3. Wind-driven shafts 5 and wind blades 6 that rotate the wind-driven shafts 5 under wind power are symmetrically arranged on both sides of the top of the mounting platform 2. Energy recovery devices 7 are arranged on both sides of the bottom of the mounting platform 2. The energy recovery devices 7 are specifically generators used to convert the mechanical kinetic energy generated when the wind blades 6 rotate into electrical energy, thereby combining with the conversion of light energy by the photovoltaic panels 3 to utilize wind and solar energy. A cleaning mechanism 8 is provided on the wind-driven shafts 5. Figure 3 As shown, the cleaning mechanism 8 includes a guide sleeve 81, an elastic pressure member 82, a sliding assembly 83, a wiping assembly 84, an elastic reset member 85, and a shock assembly 86.

[0041] Please see Figure 4 , Figure 5 and Figure 6 The guide sleeve 81 is fixed to the top surface of the mounting platform 2. The wind shaft 5 passes through the guide sleeve 81 and is rotatably connected to the mounting platform 2. The part of the wind shaft 5 located inside the guide sleeve 81 is provided with a stepped groove 51. The bottom of the stepped groove 51 is provided with a first protrusion 52 distributed in a ring around the wind shaft 5. The elastic pressure member 82 is provided inside the guide sleeve 81. The elastic pressure member 82 includes a fixed ring 821 and a sliding ring 822. The fixed ring 821 is fixed inside the guide sleeve 81, and the sliding ring 822 is slidably disposed between the guide sleeve 81 and the cavity of the wind shaft 5. An electromagnet 823 is fixed on the opposite side of the fixed ring 821 and the sliding ring 822, and the two electromagnets 823 are elastically connected by a first spring 824. When the electromagnets 823 are not in operation, the fixed ring 821 and the sliding ring 822 are moved away from each other by the elastic force of the first spring 824, thereby causing the wiping assembly 84 to be in a raised state and kept in contact with the horizontal photovoltaic panel 3. At a certain interval, the sliding component 83 is sleeved on the wind-driven shaft 5 and selectively slides up and down under the drive of the elastic pressure member 82. The sliding component 83 includes a sliding sleeve 831, which is sleeved on the wind-driven shaft 5 at the location of the stepped groove 51. A fixing rod 833 is fixed on the side wall of the sliding sleeve 831. A limiting plate 832, which is rotatably disposed in the sliding ring 822, is fixed at the bottom of the sliding sleeve 831. The bottom surface of the limiting plate 832 is provided with a second protrusion that matches the first protrusion 52. Part 834 energizes the electromagnet 823 on the fixed ring 821 and the sliding ring 822. Under the action of magnetic force, the sliding ring 822 slides downward against the elastic force of the first spring 824. This causes the sliding assembly 83 to gradually slide down with the wiping assembly 84 until the second protrusion 834 on the bottom surface of the limiting plate 832 engages with the first protrusion 52 of the wind shaft 5. Therefore, when the wind blade 6 drives the wind shaft 5 to rotate under the action of wind force, the wiping assembly 84 can rotate synchronously.

[0042] Please see Figure 7 and Figure 8The wiping assembly 84 is hinged to one side of the sliding assembly 83. The wiping assembly 84 includes a brush holder 841, which is hinged to the end of the fixed rod 833. A flexible brush 842 is fixed to the bottom of the brush holder 841. An elastic reset member 85 elastically connects the sliding assembly 83 and the wiping assembly 84. The elastic reset member 85 includes a first bracket 851, a second spring 852, and a second bracket 853. The first bracket 851 is fixed to the side of the fixed rod 833, and the second bracket 853 is fixed to the side of the brush holder 841. Spring rods 854 are fixed to the inner sides of the ends of the frame 851 and the second support 853. The two ends of the second spring 852 are respectively fixed to the spring rods 854 of the first support 851 and the second support 853. The shock component 86 cooperates with the elastic reset component 85 to stop the wiping component 84. The shock component 86 includes a suspension rod 861. One end of the suspension rod 861 is fixed to the fixed rod 833, and the other end of the suspension rod 861 is fixed to a stop rod 862. The brush seat 841 abuts against the stop rod 862 under the elastic force of the second spring 852.

[0043] Please see Figure 10 The photovoltaic panel 3 has symmetrically arranged blocking members 9 of the blocking wiping assembly 84 on both sides. The blocking member 9 includes a fixing plate 91, which is fixed to the side of the photovoltaic panel 3. A fixing shaft 92 is fixed to the end of the fixing plate 91. A roller 93 is rotatably connected to the top of the fixing shaft 92. The roller 93 is designed to reduce the friction with the brush holder 841, making the brush holder 841 smoother when rotating. A paddle 94 is fixed on the side wall of the fixing shaft 92, which can be used to clean the flexible brush 842.

[0044] Please see Figure 9 The fixing rod 833 of the left cleaning mechanism 8 is located directly below the projection of the second protrusion 834, and the fixing rod 833 of the right cleaning mechanism 8 is located directly below the projection of the midpoint of the two adjacent second protrusions 834. When the second protrusion 834 on the bottom surface of the limiting plate 832 of the left and right cleaning mechanisms 8 engages with the first protrusion 52 of the wind shaft 5, the wiping components 84 of the two cleaning mechanisms 8 can be automatically staggered to avoid motion interference when the wiping components 84 rotate.

[0045] It should be noted that after the second protrusion 834 of the cleaning mechanism 8 engages with the first protrusion 52, the roller 93 is located at the height of the brush holder 841, and the paddle 94 is located at the height of the flexible brush 842. When the second protrusion 834 on the bottom surface of the limiting plate 832 engages with the first protrusion 52 of the pneumatic shaft 5, the height of the brush holder 841 corresponds to the roller 93 of the blocking member 9, and the height of the flexible brush 842 corresponds to the paddle 94 of the blocking member 9. Therefore, when the brush holder 841 rotates to contact the roller 93, due to the obstruction of the roller 93, the brush 941 is delayed in rotation on the fixed rod 833 due to the resistance of the second spring 852.

[0046] The working principle and usage process of this invention are as follows: When it is necessary to clean the surface of the photovoltaic panel 3, the photovoltaic panel 3 is adjusted to a horizontal position by adjusting device 4. Then, by energizing electromagnet 823 on fixed ring 821 and sliding ring 822, the sliding ring 822 slides downward against the elastic force of the first spring 824 under the action of magnetic force, and the sliding component 83 carries the wiping component 84 to gradually slide down to the second protrusion 834 on the bottom surface of the limiting plate 832 and engage with the first protrusion 52 of the wind shaft 5. Therefore, when the wind blade 6 drives the wind shaft 5 to rotate under the action of wind force, the wiping component 84 can rotate synchronously and can scrape the surface of the photovoltaic panel 3.

[0047] When the second protrusion 834 on the bottom surface of the limiting plate 832 engages with the first protrusion 52 of the pneumatic shaft 5, the height position of the brush holder 841 corresponds to the roller 93 of the blocking member 9, and the height position of the flexible brush 842 corresponds to the paddle 94 of the blocking member 9. Therefore, when the brush holder 841 rotates to contact the roller 93, due to the obstruction of the roller 93, 941 is delayed in rotation on the fixed rod 833 due to the elastic force of the second spring 852. During this process, the paddle 94 moves from the brush holder 832... One end of 41 continuously scrapes the flexible brush 842 from the other end to clean the foreign matter attached to the flexible brush 842. As the fixed rod 833 continues to rotate, the brush seat 841 is separated from the roller 93. Under the elastic force of the second spring 852, the brush seat 841 rebounds quickly, that is, the rotation speed of the brush seat 841 increases until it collides with the stop rod 862 of the shock component 86, which helps to knock off the dust on the flexible brush 842 to maintain the cleaning ability of the flexible brush 842 on the photovoltaic panel 3.

[0048] After cleaning, by de-energizing the electromagnet 823 on the fixed ring 821 and the sliding ring 822, the sliding ring 822 can lift the wiping component 84 upward under the elastic force of the first spring 824, so that the flexible brush 842 leaves the surface of the photovoltaic panel 3, avoiding affecting the angle adjustment of the photovoltaic panel 3. At the same time, the sliding component 83, along with the wiping component 84, gradually rises until the second protrusion 834 on the bottom surface of the limiting plate 832 disengages from the first protrusion 52 of the wind shaft 5. That is, when the wind shaft 5 rotates, the wiping component 84 will not rotate with the wind shaft 5, thereby reducing the kinetic energy loss of the wind shaft 5 rotation, which is conducive to converting kinetic energy into electrical energy and improving utilization efficiency.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
