The power generation device also includes a plate for reflecting or absorbing the sunlight that has escaped from the receiver again. The reflectors are arranged on the ground around the power generation tower at a set angle around the power generation tower. The power generation tower is vertically fixed on the ground, and the upper part of the receiver fixes the plate through a support platform; the support platform is radial, and the plate is a disk-shaped structure with a center convex upward.

In the early stage of internal inflation, the internal air pressure is not enough to push open the one-way valve, so that the inside of the air guide groove is in a closed state. At this time, the air pressure inside the sleeve can push the slide plate to slide upward until the mounting frame contacts and presses against the limit rod.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 3As shown, a tower-type solar power generation device described in an embodiment of the present invention includes a tower body 1; a plurality of groups of reflection components are arranged around the tower body 1, and the reflection components include a support rod 2, a mounting frame 3 is connected to the top of the support rod 2, a reflection plate 4 is arranged on the mounting frame 3, a receiver 5 capable of receiving sunlight reflected by the reflection plate 4 is installed on the top of the tower body 1, a ring-shaped reflection ring 6 is connected to the bottom end of the receiver 5, a ring-shaped reflector 7 is connected to the side wall of the tower body 1 corresponding to the inside of the reflection ring 6, and the bottom end of the reflector 7 extends to the bottom outer end of the reflection ring 6, and the sunlight reflected on the reflection plate 4 can be reflected to the receiver 5 through the reflector 7 and the reflection ring 6; when the tower-type solar power generation device in the prior art is in use, although it can make full use of the sunlight reflected on the reflection plate 4 by arranging a plate on the top of the receiver 5, the arrangement of the plate will also block part of the sunlight. The sunlight is set on the reflecting plate 4, which affects the effective reflection of the sunlight by the reflecting plate 4 to a certain extent, and then has an adverse effect on the stable power generation of the power generation device; when the power generation device in the present invention is working, the reflecting plate 4, the reflecting ring 6 and the reflecting mirror 7 can be made of lenses that can reflect sunlight. By adjusting the positions of the three, after the sunlight is irradiated on the reflecting plate 4, a part of the sunlight is reflected by the reflecting plate 4 to the receiver 5, and is received to generate electricity, while the other part of the sunlight that is not reflected to the receiver 5 can be reflected to the reflecting mirror 7, and is received by the receiver 5 after multiple reflections between the reflecting mirror 7 and the reflecting ring 6, so that the sunlight reflected by the reflecting plate 4 can be more fully utilized. At the same time, the reflecting ring 6 and the reflecting mirror 7 are installed on the side wall of the tower body 1, and the volume is limited, so as to reduce the obstruction caused by the reflecting plate 4 to receiving sunlight, so that the power generation device can generate electricity more efficiently and stably.

[0031] The mounting frame 3 is rotatably connected to the top of the support rod 2, and an arc-shaped sliding sleeve 8 is connected to the side wall of the support rod 2. A slide plate 9 that fits the inner wall is slidably connected inside the sliding sleeve 8, and the top of the slide plate 9 is connected to the bottom of the top of the mounting frame 3, and the bottom of the sliding sleeve 8 is connected to the external air source through the air pipe 10; since the projection point of the sun changes with time, the air source is used to inflate and deflate the inside of the sliding sleeve 8, so that the air pressure in the sliding sleeve 8 can drive the slide plate 9 to slide in the sliding sleeve 8, so that the top of the slide plate 9 can adaptively adjust the inclination angle of the reflector 4, further improving the power generation efficiency of the device.

[0032] like Figure 3-Figure 4As shown, the slide plate 9 is provided with an air guide groove 11, and a one-way valve 12 is installed inside the air guide groove 11 for the gas inside the sliding sleeve 8 to flow out. A guide sleeve 13 is connected to the top surface of the top of the mounting frame 3, and the bottom of the guide sleeve 13 is open, and the top of the guide sleeve 13 is connected to the top of the air guide groove 11 through a conducting pipe 14. A limit rod 15 capable of limiting the rotation angle of the mounting frame 3 is connected to the side wall of the support rod 2; when debris such as leaves or plastic bags falls into the upper surface of the reflector 4, the sliding sleeve 8 is inflated through the air source, and at the same time, the valve core of the one-way valve 12 is pushed open by the force, so that the sliding sleeve 8 can be inflated. In the early stage of inflation of the sleeve 8, the air pressure inside it is not enough to push open the one-way valve 12, so that the inside of the air guide groove 11 is in a closed state. At this time, the air pressure inside the sleeve 8 can push the slide plate 9 to slide upward until the mounting frame 3 contacts and presses against the limit rod 15. Then, the air pressure inside the sleeve 8 continues to increase and can push open the one-way valve 12, so that the gas in the sleeve 8 can flow into the guide sleeve 13 through the air guide groove 11 and the guide pipe 14, and under the guidance of the guide sleeve 13, the jet is ejected from top to bottom along the surface of the reflector 4, so that impurities such as fallen leaves accumulated on its surface can be blown off, reducing the situation where the reflector 4 is blocked by debris and affects its smooth operation.

[0033] A guide plate 16 is connected to the opening at the bottom of the guide sleeve 13, and a group of evenly distributed guide grooves 17 are opened on the plate surface of the guide plate 16 along the rotation axis direction of the reflector 4; when the gas flows into the guide sleeve 13, it can be ejected separately from the guide grooves 17 of the guide plate 16, so that the gas can be ejected from the top of the reflector 4 in a larger range and the debris on the surface of the reflector 4 can be cleaned more fully.

[0034] The guide plate 16 corresponding to the outer end of the guide groove 17 is connected with a telescopic bag 18 connected to the inside of the guide sleeve 13, the side wall shape of the telescopic bag 18 is set to be wavy, and the bottom end of the telescopic bag 18 is connected with a scraper 19; when the telescopic bag 18 is not inflated, it is in a contracted state and is located at the top of the reflector 4, so as not to block the reflector 4, when the gas is ejected from the inside of the guide sleeve 13, the gas can stretch the telescopic bag 18 after flowing into the telescopic bag, and drive the scraper 19 to scrape the surface of the reflector 4 from top to bottom, so that the debris on the surface can be scraped off and cleaned more fully and effectively.

[0035] The bottom end of the scraper 19 is connected to a cleaning layer 20 made of sponge material, and the top surface of the bottom of the installation frame 3 is connected to a water tank 21, and the top of the water tank 21 is open. By pre-filling water into the water tank 21, the open water tank 21 can also collect rainwater, so that when the telescopic bag 18 is extended, it can drive the cleaning layer 20 on the scraper 19 to move into the water tank 21, and make the cleaning layer 20 absorb water. Then, when the telescopic bag 18 shrinks and resets, the telescopic bag 18 can drive the water-absorbing cleaning layer 20 to slide across the surface of the reflective plate 4, and can further scrape and clean the dust and impurities on the surface of the reflective plate 4, thereby further improving the smoothness of the reflective plate 4, so that the reflective plate 4 can reflect sunlight more efficiently.

[0036] Embodiment 2: Figure 5-Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a sealing plate 22 is rotatably connected to the side wall of the opening at the top of the water storage tank 21 through an elastic reset component, and the other end of the sealing plate 22 is in contact with the surface of the reflecting plate 4, and a top block 23 is connected to the bottom of the scraper 19; the sealing plate 22 can seal the opening at the top of the water storage tank 21 under the action of the elastic reset component, thereby reducing the evaporation and loss of water stored in the water storage tank 21 due to long-term exposure. When the telescopic bag 18 drives the scraper 19 to move to the sealing plate 22, the top block 23 can be used to push the sealing plate 22 open, so that the cleaning layer 20 can smoothly enter the water storage tank 21 to absorb water. At the same time, on rainy days, as rainwater gradually accumulates on the top of the sealing plate 22, the sealing plate 22 can be rotated under the action of rainwater, so that the rainwater accumulated on the sealing plate 22 can smoothly flow into the water storage tank 21, thereby improving the ability of the water storage tank 21 to work continuously.

[0037] A slide groove is provided at one end of the scraper 19 connected to the cleaning layer 20, and a slider 24 is slidably connected inside the slide groove, and a spring is connected between the slider 24 and the inner end of the slide groove. A pressure block 25 is provided inside the cleaning layer 20, and a pull rope 26 is connected between the pressure block 25 and the outer end of the slider 24. A magnetic block 27 capable of attracting the pressure block 25 is installed on the side wall of the water tank 21 away from the reflecting plate 4; when the telescopic bag 18 drives the scraper 19 to move to the inside of the water tank 21, the magnetic block 27 can attract the pressure block 25, so that the pressure block 25 squeezes the cleaning layer 20, promotes the outflow of dust and impurities remaining due to the last scraping of the reflecting plate 4, so that the cleaning layer 20 achieves a "self-cleaning" effect, thereby improving the subsequent cleaning effect of the cleaning layer 20 on the reflecting plate 4.

[0038] A partition 28 is connected to the side wall at the bottom of the water storage tank 21, a leakage groove 29 is opened on the plate surface of the partition 28, and an elastic eardrum 30 is connected to the side wall of the leakage groove 29. The elastic reset component is composed of an elastic pressure bag 31, one end of the pressure bag 31 is connected to the bottom surface of the connecting end of the blocking plate 22, and the other end of the pressure bag 31 is connected to the side wall of the water storage tank 21 away from the reflecting plate 4. An airway 32 connecting the various chambers inside the eardrum 30 is opened inside the partition 28, and a hose 33 is connected between the air inlet end of the airway 32 and the pressure bag 31; when the dust and impurities on the cleaning layer 20 are squeezed out, the dust mud The soil will gradually settle and pass through the leakage groove 29 to accumulate at the bottom of the water tank 21. When the scraper 19 squeezes the sealing plate 22 driven by the telescopic bag 18, the sealing plate 22 rotates counterclockwise to introduce the gas in the pressure bag 31 into the eardrum 30 through the hose 33 and the airway 32, so that the eardrum 30 expands and blocks the leakage groove 29, thereby reducing the situation where the scraper 19 enters the water tank 21 and the soil accumulated at the bottom will vibrate and cause the water to become turbid, thereby affecting the cleaning effect of the cleaning layer 20, so that the cleaning layer 20 can come into contact with clearer water, further improving the cleaning effect of the cleaning layer 20 on the reflecting plate 4.

[0039] The width of the slot of the leakage groove 29 gradually increases from the middle to the two ends, and the outer edge of one end of the leakage groove 29 close to the sealing plate 22 fits each other; by setting the shape of the leakage groove 29 and the positional relationship between the two adjacent ones, the deposited soil can flow in from the top of the leakage groove 29 with a larger width and be collected, thereby improving the stratification effect of clean water and soil inside the water tank 21.

[0040] Working principle: When the power generation device of the present invention is working, the reflector 4, the reflector ring 6 and the reflector 7 can be made of lenses that can reflect sunlight. By adjusting the positions of the three, after the sunlight irradiates the reflector 4, a part of the sunlight is reflected by the reflector 4 to the receiver 5, and is received to generate electricity, while the other part of the sunlight that is not reflected to the receiver 5 can be reflected to the reflector 7, and is received by the receiver 5 after multiple reflections between the reflector 7 and the reflector ring 6, so that the sunlight reflected by the reflector 4 can be more fully utilized. At the same time, the reflector ring 6 and the reflector 7 are installed on the side wall of the tower body 1, and The volume is limited, thereby reducing the obstruction of the reflector 4 from receiving sunlight, so that the power generation device can generate electricity more efficiently and stably; because the projection point of the sun changes with time, the air source is used to inflate and deflate the inside of the sleeve 8, so that the air pressure in the sleeve 8 can drive the slide plate 9 to slide in the sleeve 8, so that the top of the slide plate 9 can adaptively adjust the inclination angle of the reflector 4, further improving the power generation efficiency of the device; when debris such as leaves or plastic bags fall on the upper surface of the reflector 4, the air source is used to inflate the inside of the sleeve 8, and at the same time, the force of the valve core of the one-way valve 12 being pushed open is used to set the one-way valve 12. In the early stage of inflation of the sleeve 8, the air pressure inside is not enough to push open the one-way valve 12, so that the inside of the air guide groove 11 is in a closed state. At this time, the air pressure inside the sleeve 8 can push the slide plate 9 to slide upward until the mounting frame 3 contacts and presses against the limit rod 15. Then, the air pressure inside the sleeve 8 continues to increase and can push open the one-way valve 12, so that the gas in the sleeve 8 can flow into the guide sleeve 13 through the air guide groove 11 and the guide pipe 14, and under the guidance of the guide sleeve 13, the gas is ejected from top to bottom along the surface of the reflector 4, so that impurities such as fallen leaves accumulated on the surface can be blown off, reducing the impact of debris on the reflector 4. The air flows into the guide sleeve 13, and the air can be ejected from the guide grooves 17 of the guide plate 16 respectively, so that the air can be ejected from the top of the reflector 4 in a wider range, and the debris on the surface of the reflector 4 can be cleaned more fully; when the telescopic bag 18 is not inflated, it is in a contracted state and located at the top of the reflector 4, so that the reflector 4 will not be blocked. When the gas is ejected from the guide sleeve 13, the gas can extend the telescopic bag 18 after flowing into the telescopic bag 18, and drive the scraper 19 to scrape the surface of the reflector 4 from top to bottom, so that the debris on the surface can be scraped off more fully and effectively.By pre-filling the water storage tank 21 with water, and the open water storage tank 21 being able to collect rainwater, the telescopic bag 18 can drive the cleaning layer 20 on the scraper 19 to move into the water storage tank 21 when it is extended, and make the cleaning layer 20 absorb water. Then, when the telescopic bag 18 is contracted and reset, the telescopic bag 18 can drive the cleaning layer 20 that absorbs water to slide across the surface of the reflective plate 4, and can further scrape and clean the dust and impurities on the surface of the reflective plate 4, further improving the smoothness of the reflective plate 4, so that the reflective plate 4 can reflect sunlight more efficiently. The blocking plate 22 can be pressed against the top of the water storage tank 21 under the action of the elastic reset component. The opening of the top of the water tank 21 is blocked, thereby reducing the evaporation and loss of water stored in the water tank 21 due to long-term exposure. When the telescopic bag 18 drives the scraper 19 to move to the blocking plate 22, the blocking plate 22 can be pushed open by the top block 23, so that the cleaning layer 20 can smoothly enter the water tank 21 to absorb water. At the same time, on rainy days, as rainwater gradually accumulates on the top of the blocking plate 22, the blocking plate 22 can rotate under the action of rainwater, so that the rainwater accumulated on the blocking plate 22 can smoothly flow into the water tank 21, thereby improving the continuous working ability of the water tank 21. When the scraper 19 moves into the water tank 21, the magnetic block 27 can attract the pressing block 25, so that the pressing block 25 squeezes the cleaning layer 20, promotes the outflow of dust and impurities remaining from the last scraping of the reflecting plate 4, and makes the cleaning layer 20 achieve a "self-cleaning" effect, thereby improving the subsequent cleaning effect of the cleaning layer 20 on the reflecting plate 4; when the dust and impurities on the cleaning layer 20 are squeezed out, the dust and mud will gradually settle and pass through the leakage groove 29 to accumulate at the bottom of the water tank 21, and when the scraper 19 squeezes the sealing plate 22 driven by the telescopic bag 18, the sealing plate 22 rotates counterclockwise to push the gas in the pressure bag 31 through the soft The tube 33 and the air passage 32 are introduced into the eardrum 30, so that the eardrum 30 expands to block the leakage groove 29, thereby reducing the situation that the soil accumulated at the bottom of the scraper 19 will vibrate after entering the water storage tank 21, causing the water to be turbid, thereby affecting the cleaning effect of the cleaning layer 20, so that the cleaning layer 20 can contact with clearer water, further improving the cleaning effect of the cleaning layer 20 on the reflector 4; by setting the shape of the leakage groove 29 and the positional relationship between the two adjacent ones, the deposited soil can flow in from the top of the leakage groove 29 with a larger width and be collected, thereby improving the stratification effect of the clean water and soil in the water storage tank 21. ;
