Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a buffer and shock-absorbing base for a photovoltaic power station generator. Background Technology

[0002] As is well known, photovoltaic power generation mainly consists of three parts: solar panels, controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. When electricity needs to be transmitted, the photovoltaic power station will start the photovoltaic generator. When photovoltaic power generation and transmission are carried out, because the amount of electricity transmitted is very large, it will generate violent vibrations.

[0003] Currently, photovoltaic generators in general photovoltaic power stations are mainly fixed with screws. Because the generator vibrates, the screws may loosen, causing abnormal vibrations that affect the efficiency of photovoltaic power generation. Abnormal vibrations can also cause the rotor retaining ring of the generator to loosen and wear, and in severe cases, it can cause core ring damage and insulation wear of the circuit, leading to short circuits and grounding faults. To ensure the stable operation of photovoltaic generators, a buffer and vibration damping base for photovoltaic power station generators is needed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a buffer and shock-absorbing base for a photovoltaic power station generator, which has the following beneficial effects:

[0015] The generator buffer and vibration damping base of this photovoltaic power station adopts a multi-stage vibration damping design to reduce the vibration of the generator. During operation, the vibration is transmitted through fixed components. The first-stage vibration damping component reduces the vibration of the generator to a certain extent. When the vibration is transmitted again, the second-stage vibration damping component ensures that the vibration is reduced again. After the generator passes through multiple stages of vibration damping, the vibration effect is reduced multiple times. This reduces the abnormal vibration that may loosen and wear the rotor retaining ring of the generator, making it less likely to cause core ring damage and insulation wear of the circuit, thus preventing short circuit faults and grounding faults, and ensuring the stable operation of the photovoltaic generator.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-6 A photovoltaic power station generator buffer and vibration damping base includes a holding base 1, characterized in that it further includes a placement groove, a primary vibration damping component, a power component, a fixing component, a secondary vibration damping component, and an auxiliary component, all made of high-strength and corrosion-resistant materials (e.g., alloy steel). The placement groove is formed on the holding base 1. The primary vibration damping component is installed on the inner wall of the placement groove, acting as a primary vibration damping component for the photovoltaic generator. The fixing component is installed on top of the primary vibration damping component, acting to fix the photovoltaic generator so that vibrations can be transmitted to the primary vibration damping component. The power component is installed inside the primary vibration damping component, acting as a power transmission component for the fixing component. The secondary vibration damping component is installed on the outer wall of the primary vibration damping component, acting as a secondary vibration damping component for the photovoltaic generator. The auxiliary component is installed on the secondary component to assist the vibration damping function of the secondary vibration damping component.

[0025] First, refer to Figure 1 and Figure 3The primary damping component includes an air damper 2, a placement plate 3, and a first slide groove. The bottom of each air damper 2 is fixed to the holding base 1 by welding. Although four air dampers 2 are shown in the attached drawings of the instruction manual, one or more suitable air damper 2 devices can be installed on the holding base 1 according to actual needs. As the main body of the primary damping, the air damper 2 not only supports the placement plate, but also dampens the photovoltaic generator, making the photovoltaic generator suitable for various environments, such as earthquakes and moving objects, and preventing the photovoltaic generator from vibrating violently. The placement plate 3 is fixed to the top of each air damper 2 by welding. The placement plate 3 is a component for placing the photovoltaic generator and has the characteristics of high strength. Each first slide groove is opened on both sides of the holding base 1, and each first slide groove has four first slide grooves. The inner wall of the first slide groove is a smooth plane.

[0026] Then, refer to Figure 4 The power assembly includes a hydraulic rod 4, a second slide groove, a first slider 5, and a power plate 6. The base of the hydraulic rod 4 is welded to the bottom of the placement plate 3. As the main body of the power assembly, the hydraulic rod 4 needs to have high strength to firmly fix the motor and transmit its vibration to the first-stage shock absorption assembly. The second slide groove is located at the bottom of the placement plate 3. The inner wall of the second slide groove is a smooth plane, and the first slider 5 is adapted to the second slide groove. The first slider 5 is slidably connected to the inner wall of the second slide groove. The first slider 5 and the second slide groove are tightly fitted together. The first slider 5 can withstand frequent friction and slight impacts, allowing the first slider 5 to move linearly at the bottom of the placement plate 3. To prevent damage to the first slider 5, it is made of a high-strength and corrosion-resistant material (such as alloy steel). The power plate 6 is fixedly connected to the bottom of the first slider 5, and the bottom end of the power plate 6 is welded to the output end of the hydraulic rod 4. The movement of the hydraulic rod 4 drives the placement plate 3 to move.

[0027] Secondly, see Figure 2 and Figure 3The fixing assembly includes a first through hole, a first rotating shaft 7, a movable rod 8, a second through hole, a second rotating shaft 9, a sliding rod 10, and a clamping plate 11. The first through holes are located on both sides of the bottom end of the power plate 6, and there are four first through holes. The surface of each first through hole is a smooth plane. Each first rotating shaft 7 is rotatably connected to the inner wall of the first through hole, and the first rotating shaft 7 fits tightly with the first through hole. There are four first rotating shafts 7, which can withstand the frictional force generated by frequent rotation. The bottom end of each movable rod 8 is rotatably connected to the bottom of the power plate 6 via the first rotating shaft 7, and there are four movable rods 8. To ensure that the movable rods 8 can adapt to high-intensity work and withstand the thrust transmitted to the movable rods 8 by the transmission hydraulic rod 4, the movable rods 8 are made of a high-strength, corrosion-resistant material (such as titanium steel plate). Each second through hole is located at the top end of the movable rod 8, and there are four second through holes. Each second rotating shaft 9 is rotatably connected to the inner wall of the first through hole. Four second rotating shafts 9 are installed on the inner wall of the second through hole. The bottom end of each sliding rod 10 is rotatably connected to the top end of the movable rod 8 through the second rotating shaft 9. The sliding rod 10 slides in the first sliding groove. Four sliding rods 10 are installed. In order to ensure that the sliding rod 10 can adapt to high-intensity work, the sliding rod 10 is made of high-strength corrosion-resistant material (such as titanium steel plate). Each clamping plate 11 is fixedly connected to the top end of each sliding rod 10. There are two clamping plates 11. The clamping plates 11 are mainly responsible for clamping the top of the photovoltaic generator and reducing vibration. Therefore, the surface of the clamping plate 11 has a layer of hard rubber. As the main body for fixing the photovoltaic generator, the clamping plate 11 needs to bear the tension of clamping the generator and the vibration generated by the generator operation, so as to provide stable support for the photovoltaic generator. The clamping plate 11 drives the sliding rod 10 to retract inward and outward through the up and down translational movement of the movable rod 8, which in turn drives the clamping plate 11 to retract.

[0028] Again, see Figure 5 and Figure 6The secondary damping assembly includes a first connecting base 12, a third through hole, a third rotating shaft 13, a damping rod 14, a sliding base 15, a fourth through hole, a damping support leg 16, a fifth through hole, a connecting column 17, a first spring 18, and a second spring 19. Each of the four first connecting bases 12 is fixedly connected to the side wall of the holding base 1 by welding. Each of the four third through holes is located on the side wall of the first connecting base 12. The inner wall of each third through hole is a smooth plane. The third through holes are connected to the third rotating shaft 13. To ensure proper fit, each third rotating shaft 13 is rotatably connected to the inner wall of the third through hole, with a tight fit between them. Four third rotating shafts 13 are installed. Each shock-absorbing rod 14 is rotatably connected to the first connecting base 12 via the third rotating shaft 13. Four shock-absorbing rods 14 are also installed. The first connecting base 12 is mainly used to connect the holding base 1, allowing its vibration to be transmitted to the shock-absorbing rods 14 for damping. Each sliding base 15 is fixedly connected to the top of the shock-absorbing rod 14 by welding. Four sliding bases 15 are also installed. Each fourth through hole is opened on the sliding base 15. Four shock-absorbing legs 16 are provided, each mounted on a sliding base 15. Four fifth through holes are provided on the top of each shock-absorbing leg 16. Each connecting post 17 is fixedly connected to the inside of a fifth through hole by welding. The sliding base 15 is slidably connected to each other through a fourth through hole. The connecting posts 17 serve as the connection method to the sliding base 15. The design of the connecting posts 17 needs to have sufficient strength to withstand the tensile force generated by vibration. The top of each first spring 18... All are fixedly connected to the top of the fifth through hole, and the bottom of the first spring 18 is fixedly connected to the top of the sliding base 15. Four first springs 18 are installed. The bottom of each second spring 19 is fixedly connected to the bottom of the fifth through hole, and the top of each second spring 19 is fixedly connected to the bottom of the sliding base 15. Four second springs 19 are installed. The shock-absorbing rod 14 achieves the shock-absorbing effect of the holding base 1 connected to the shock-absorbing rod 14 through the elastic force of the first spring 18 and the second spring 19. The first spring 18 and the second spring 19 are made of a rigid material with high strength (such as spring steel SK85).

[0029] Finally, see Figure 5 and Figure 6The auxiliary components include a second connecting base 20, a sixth through hole, a fourth rotating shaft 21, a third connecting base 22, a seventh through hole, a fifth rotating shaft 23, and a shock absorber 24. Each second connecting base 20 is fixedly connected to the inner wall of the shock-absorbing leg 16 by welding. Four second connecting bases 20 are installed. Each second connecting base 20 has sufficient strength and stability to withstand the pressure exerted by the photovoltaic generator. Each sixth through hole is opened on the side wall of the second connecting base 20, and four sixth through holes are provided. Each fourth rotating shaft 21 is rotatably connected to the inner wall of the sixth through hole, and four fourth rotating shafts 21 are installed. Each third connecting base 22 is fixedly connected to the inner wall of the shock-absorbing leg 16 by welding. On the inner wall of the shock absorber 14, the third connecting base 22 has sufficient strength and stability to withstand the pressure given by the photovoltaic generator. Each seventh through hole is opened on the side wall of the third connecting base 22, and there are four seventh through holes. Each fifth rotating shaft 23 is rotatably connected to the inner wall of the seventh through hole, and there are four fifth rotating shafts 23. The bottom end of each shock absorber 24 is rotatably connected to the second connecting base 20 through the fourth rotating shaft 21, and the output end of each shock absorber 24 is rotatably connected to the third connecting base 22 through the fifth rotating shaft 23. There are four shock absorbers 24. The shock absorbers 24 mainly function to assist the secondary shock absorption components and alleviate larger vibrations.

[0030] Working principle:

[0031] When using the photovoltaic power station generator buffer and shock absorption base, first place the photovoltaic power station generator buffer and shock absorption base in the desired position. First, place the photovoltaic generator. Specifically, first place the photovoltaic generator on the placement plate 3, and then push the power plate 6 by controlling the hydraulic rod 4 of the power component. The power plate 6 moves forward through the first slider 5 fixed at the bottom. The power plate 6 drives the movable rod 8 to retract inward along the first slide groove. The first movable rod 8 drives the sliding rod 10, and the sliding rod 10 drives the clamping plate 11 to move inward together, thereby fixing the photovoltaic generator by moving it.

[0032] Then, the photovoltaic generator is started. The specific operation is as follows: the photovoltaic generator starts to operate and the photovoltaic generator starts to vibrate. The vibration is transmitted to the first-level shock absorption component through the clamp 11. The first-level shock absorption component weakens the vibration through the air damper 2. The weakened vibration is transmitted to the holding base 1. The holding base 1 and the first connecting base 12 are fixed. The first connecting base 12 transmits the vibration to the shock absorption rod 14. The shock absorption rod 14 reduces the vibration again through the cooperation of the first spring 18 and the second spring 19, greatly reducing the vibration. For particularly severe vibrations, the vibration is transmitted to the shock absorber 24 in the auxiliary component for weakening.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
