Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically an adjustable photovoltaic support for mountainous areas. Background Technology

[0002] Photovoltaic brackets are structural components in solar photovoltaic power generation systems specifically designed to support, fix, and protect photovoltaic modules. Their core function is to bear the weight of the photovoltaic panels and safely transfer external forces such as wind loads, snow loads, and seismic forces to the foundation, while ensuring that the modules maintain a specific orientation and tilt angle to maximize power generation efficiency. Because photovoltaic power generation has high requirements for sunshine conditions, mountainous areas are usually open, unobstructed, and have thinner and cleaner air, thus having longer sunshine hours and higher solar radiation intensity, which is conducive to improving the power generation efficiency of photovoltaic systems. Based on this, some photovoltaic power stations choose to install photovoltaic panels in mountainous areas to obtain better sunshine resources. When installing photovoltaic (PV) brackets in mountainous areas, the installation location needs to be determined based on sunlight conditions, slope, and geological conditions. Once the location is determined, it is often difficult to change. In addition, some mountainous areas have soft soil. If PV brackets are installed in such areas, soil is easily splashed by raindrops and adheres to the surface of the bracket structure when rain occurs. When seasonal adjustments to the bracket angle are needed, the soil adhering to the sliding mechanism will increase frictional resistance and may even cause jamming, seriously affecting the smoothness and reliability of the adjustment operation. Therefore, we propose an adjustable PV bracket for mountainous areas. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable photovoltaic support for mountainous areas to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable photovoltaic support for mountainous areas, comprising a base, wherein two bases are provided, and a telescopic rod is fixedly connected to the top of each of the two bases. A load-bearing rod is rotatably connected to the top of each telescopic rod. A diagonal brace is rotatably connected to one side of the telescopic rod. A slider is rotatably connected to the end of the diagonal brace away from the telescopic rod. The slider is slidably connected to the bottom of the load-bearing rod on the same side. Several sand-guiding grooves are provided at both ends of the slider. A sand-discharging groove corresponding to the number and position of the sand-guiding grooves is provided at the bottom of the slider. A movable block is slidably connected inside the sand guiding channel. A magnetic plate is embedded and fixedly connected to the movable block. An installation groove is provided on the top of the movable block. A spring is fixedly connected between the inner bottom wall of the movable block and the inner top wall of the sand discharge channel. An electromagnet is fixedly connected to the inner top wall of the sand discharge channel.

[0005] Preferably, the sand guiding channel and the sand discharge channel at each corresponding position are interconnected, and a guide strip is fixedly connected inside the sand guiding channel.

[0006] Preferably, a mounting bracket is fixedly connected to the bottom opening of the sand discharge trough, and a shaft is rotatably connected between the top of the mounting bracket and the inner top wall of the sand discharge trough. A threaded groove is provided at the top end of the outer wall of the shaft, and a spiral guide plate is fixedly connected at the bottom end of the outer wall of the shaft.

[0007] Preferably, the shaft passes through the magnet plate and the electromagnet, and the magnet plate is threadedly connected to the threaded groove.

[0008] Preferably, a main water conveying channel is provided inside both sides of the slider, and a secondary water conveying channel is provided between each sand discharge trough and the main water conveying channel. The secondary water conveying channel is connected to the main water conveying channel, and a connecting pipe connected to the main water conveying channel is fixedly connected to one side of the slider.

[0009] Preferably, the movable block has a flow guide opening on one side of the secondary water conveyance channel near the corresponding position, and the bottom of the movable block is fitted and fixedly connected with several evenly distributed permeable plates.

[0010] Preferably, a protective sleeve is fixedly connected to the bottom of the magnet plate. The protective sleeve is fitted onto the threaded groove on the outer wall of the shaft, and the length of the protective sleeve is the same as the axial length of the threaded groove.

[0011] Preferably, the guide bar has a guide slope on the side away from the sand discharge trough, and the thickness of the guide bar is greater than the thickness of the moving block.

[0012] Preferably, the bottom of the load-bearing rod is provided with a number of evenly distributed positioning holes, and a number of mounting rods are fixedly connected between the tops of the two load-bearing rods.

[0013] Preferably, a screw is threadedly connected to the slider, the screw passes through the slider, the screw is threadedly connected to one of the positioning holes on the load-bearing rod on the same side, and a knob is fixedly connected to the bottom of the screw.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides sand guide grooves at both ends of the slider and a corresponding sand discharge groove at the bottom of the slider. A guide bar with a guide slope is installed within the sand guide groove. When the slider slides along the bottom of the load-bearing rod, it applies pressure to the soil attached to the bottom of the load-bearing rod. Simultaneously, the guide bar scoops up the soil through the guide slope. Under pressure, the soil preferentially accumulates in the sand guide groove where resistance is lower, and eventually falls into the sand discharge groove. This prevents soil from continuously accumulating on the sliding contact surface between the slider and the load-bearing rod, thus avoiding jamming. This effectively improves the smoothness of the slider's sliding in soft soil conditions and the reliability of the support adjustment.

[0015] 2. In this invention, an electromagnet is fixedly connected to the top wall of the sand discharge trough, and a magnetic plate is embedded and fixedly connected to the sliding block. The electromagnet and the magnetic plate are arranged with the same magnetic poles facing each other. When the electromagnet is energized, it generates a repulsive force to push the moving block downward along the sand discharge trough, pushing the accumulated soil out of the sand discharge trough. After the power is cut off, the spring drives the moving block to automatically reset, realizing the automatic cleaning function of the sand discharge trough. This avoids the problem that too much soil accumulates in the sand discharge trough, which prevents subsequent soil in the sand guide trough from entering the sand discharge trough.

[0016] 3. This invention features a threaded groove shaft rotatably connected to the bottom opening of the sand discharge trough, with a magnetic plate threadedly connected to the groove. A spiral guide plate is fixedly connected to the shaft. When the magnetic plate is driven downwards by an electromagnet, the magnetic plate and the threaded groove convert linear motion into rotational motion of the shaft, causing the guide plate to rotate synchronously. The stirring and pushing action of the guide plate breaks up and accelerates the discharge of the compacted soil in the sand discharge trough. When the moving block and magnetic plate return to their original positions and move upwards, the guide plate rotates in the opposite direction with the shaft. Through short-term alternating stirring in both directions, the soil is further broken up and loosened, avoiding the problem of compacted soil being difficult to discharge due to its dense structure. This effectively improves the efficiency of sludge discharge and the cleaning effect. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 This invention provides a technical solution: an adjustable photovoltaic support for mountainous areas, comprising a base 1, wherein two bases 1 are provided, and a telescopic rod 11 is fixedly connected to the top of each of the two bases 1. A load-bearing rod 2 is rotatably connected to the top of each telescopic rod 11. Several evenly distributed positioning holes 21 are opened at the bottom of the load-bearing rod 2. Several mounting rods 22 are fixedly connected between the tops of the two load-bearing rods 2. A diagonal brace 3 is rotatably connected to one side of the telescopic rod 11. A slider 31 is rotatably connected to the end of the diagonal brace 3 away from the telescopic rod 11. The slider 31 is slidably connected to the bottom of the load-bearing rod 2 on the same side. A screw 32 is threadedly connected to the slider 31. The screw 32 passes through the slider 31 and is threadedly connected to one of the positioning holes 21 on the load-bearing rod 2 on the same side. A knob 33 is fixedly connected to the bottom of the screw 32.

[0021] Furthermore, during the installation of the photovoltaic panels, the base 1 is first buried in the pre-buried pit on the mountain. Then, the height of the two telescopic rods 11 is manually adjusted to ensure that both ends of the installation rod 22 are at the same level, avoiding additional stress or torsional deformation of the photovoltaic panels due to unevenness of the installation rod 22. Then, the screw 32 is rotated by the knob 33 to pull it out of the positioning hole 21, thereby releasing the rotation constraint on the load-bearing rod 2. Then, the load-bearing rod 2 is rotated to adjust its tilt angle with the installation rod 22. According to the local latitude and seasonal sunlight requirements, the angle of the load-bearing rod 2 is adjusted appropriately. During the adjustment process, the slider 31 will slide along the bottom of the load-bearing rod 2 to the corresponding position. After the angle of the load-bearing rod 2 is adjusted, it is necessary to ensure that the screw 32 is aligned with the corresponding positioning hole 21. Then, the screw 32 is rotated in the opposite direction by the knob 33 to insert the screw 32 into the positioning hole 21, thereby locking the angle of the load-bearing rod 2. Finally, the photovoltaic panels are installed on the installation rod 22, and the photovoltaic panels perform photoelectric conversion to realize the power generation function.

[0022] Combined with appendix Figure 3 , Figure 4 and Figure 5 As shown, both ends of the slider 31 are provided with a plurality of sand guiding grooves 4. The bottom of the slider 31 is provided with a sand discharge groove 41 corresponding to the number and position of the sand guiding grooves 4. A moving block 5 is slidably connected in the sand guiding groove 4. A magnet plate 51 is embedded and fixedly connected to the moving block 5. An installation groove is provided on the top of the moving block 5. A spring 6 is fixedly connected between the inner bottom wall of the moving block 5 and the inner top wall of the sand discharge groove 41. The installation groove is used to accommodate the spring 6. An electromagnet 61 is fixedly connected to the inner top wall of the sand discharge groove 41. The like poles of the electromagnet 61 and the magnet plate 51 are opposite to each other. The sand guiding grooves 4 and the sand discharge grooves 41 at each corresponding position are interconnected. A guide strip 42 is fixedly connected in the sand guiding groove 4. A guide slope is provided on the side of the guide strip 42 away from the sand discharge groove 41. The thickness of the guide strip 42 is greater than the thickness of the moving block 5.

[0023] Furthermore, when seasonal adjustments to the angle of the photovoltaic panel are needed, the photovoltaic panel is first removed, and then the angle of the support rod 2 is adjusted. During this process, the slider 31 slides along the bottom of the support rod 2. Soil splashed and attached to the bottom of the support rod 2 due to raindrop impact during the rainy season is pushed by the slider 31. At this time, the slider 31 applies pressure to the soil. When the slider 31 slides on the support rod 2, a compression zone is formed between the bottom of the slider 31 and the surface of the support rod 2. When the soil particles are compressed, they will move along the pressure gradient in the direction of least resistance. The opening of the sand guide trough 4 provides a low-resistance channel for the soil. Therefore, the soil will actively enter the sand guide trough 4 under pressure, instead of remaining on the sliding contact surface between the support rod 2 and the slider 31. At the same time, the guide strip 42 scrapes up the soil attached to the bottom of the support rod 2 and guides it into the sand guide trough 4 through the scraping action of its guide slope, so that the soil accumulates in the sand guide trough 4 and eventually enters the support rod 2. Because the thickness of the guide bar 42 is greater than the thickness of the moving block 5, soil can directly pass over the moving block 5 and accumulate in the sand discharge trough 41 below it. After the angle of the load-bearing rod 2 is adjusted, the electromagnet 61 can be energized. After the electromagnet 61 is energized, it generates a magnetic field with the same polarity as the magnet plate 51. According to the principle of like poles repulsion, the magnet plate 51 is affected by the repulsive force, which will generate a downward pushing force on the moving block 5, pushing the moving block 5 to move along the sand discharge trough 41 towards the bottom opening. As the moving block 5 moves downward, the spring 6 is stretched, and during the downward movement, the moving block 5 pushes out the soil accumulated in the sand discharge trough 41 through the bottom opening of the sand discharge trough 41, thus cleaning the sand discharge trough 41. After that, the electromagnet 61 is de-energized, the repulsive force between the electromagnet 61 and the magnetic plate 51 disappears, and the spring 6 rebounds by its own elastic force, driving the moving block 5 to reset upward, so that the sand guide trough 4 and the sand discharge trough 41 are reconnected, making it easier for subsequent soil to continue to fall into the sand discharge trough 41.

[0024] Combined with appendix Figure 4 , Figure 6 and Figure 7 As shown, a mounting bracket 7 is fixedly connected to the bottom opening of the sand discharge trough 41. A shaft 71 is rotatably connected between the top of the mounting bracket 7 and the inner top wall of the sand discharge trough 41. A threaded groove 72 is provided at the top end of the outer wall of the shaft 71. A spiral guide plate 73 is fixedly connected at the bottom end of the outer wall of the shaft 71. The shaft 71 passes through the magnet plate 51 and the electromagnet 61. The magnet plate 51 is threadedly connected to the threaded groove 72. A protective sleeve 53 is fixedly connected to the bottom of the magnet plate 51. The protective sleeve 53 is sleeved on the shaft 71. The length of the protective sleeve 53 is the same as the axial length of the threaded groove 72. The protective sleeve 53 is sleeved at the threaded groove 72 opened on the outer wall of the shaft 71.

[0025] Furthermore, during the downward movement of the moving block 5 and the magnetic plate 51, since the magnetic plate 51 is connected to the threaded groove 72 through a threaded engagement, when the magnetic plate 51 moves linearly along the axis of the shaft 71, it is guided by the inclined surface of the thread, and the linear motion of the magnetic plate 51 is forcibly converted into the rotational motion of the shaft 71, thereby driving the shaft 71 to rotate. When the shaft 71 rotates, the spiral guide plate 73 fixed at its bottom rotates synchronously. On the one hand, the stirring action of the guide plate 73 breaks up and crushes the compacted soil in the sand discharge trough 41, destroying its overall structure. On the other hand, the spiral surface of the guide plate 73... The pushing action applies a downward thrust to the soil, accelerating the soil discharge. At the same time, the protective sleeve 53 forms a protective barrier for the threaded groove 72, preventing soil from entering the threaded area and causing jamming, ensuring that the magnetic plate 51 and the threaded groove 72 always cooperate smoothly. When the moving block 5 and the magnetic plate 51 are reset and moved upward, the magnetic plate 51 will cooperate with the threaded groove 72, driving the shaft 71 to rotate in the opposite direction. At this time, the guide plate 73 rotates in the opposite direction with the shaft 71. Through a short period of alternating forward and reverse stirring, the soil is further broken and loosened, making it easier for the soil to fall out of the sand discharge trough 41 automatically by gravity after the moving block 5 is reset.

[0026] Combined with appendix Figure 3 , Figure 4 and Figure 5 As shown, the slider 31 has a main water conveying channel 8 on both sides, and a secondary water conveying channel 81 is provided between each sand discharge trough 41 and the main water conveying channel 8. The secondary water conveying channel 81 is connected to the main water conveying channel 8. A connecting pipe 82 connected to the main water conveying channel 8 is fixedly connected to one side of the slider 31. A guide port 54 is provided on the side of the moving block 5 near the corresponding secondary water conveying channel 81. Several evenly distributed permeable plates 52 are fitted and fixedly connected to the bottom of the moving block 5.

[0027] Furthermore, when a large amount of soil accumulates in the sand discharge trough 41 and hardens due to long-term accumulation, an external water source can be connected to the connecting pipe 82 to inject water into the main water supply channel 8. The water flows through the main water supply channel 8 and is distributed to each secondary water supply channel 81. It enters the installation groove of the moving block 5 through the guide port 54, and then permeates evenly into the soil in the sand discharge trough 41 through the permeable plate 52, fully wetting the soil. The water flow seeps into the micropores between the soil particles, weakening the bonding force between the particles. At the same time, some mineral components expand when they come into contact with water, making the originally tightly compacted soil blocks loose, greatly reducing the difficulty and resistance during subsequent cleaning, and facilitating smooth discharge under the drive of the electromagnet 61 or the action of gravity.

[0028] Working principle: First, bury the two bases 1 into the pre-buried pit in the mountain. Manually adjust the height of the telescopic rod 11 so that both ends of the installation rod 22 are on the same horizontal plane. Then, rotate the screw 32 through the knob 33 to make it unscrew from the positioning hole 21, releasing the rotation constraint of the load-bearing rod 2. Then rotate the load-bearing rod 2 to adjust to the required tilt angle. At this time, the slider 31 slides along the bottom of the load-bearing rod 2 to the corresponding position. After the angle is adjusted, align the screw 32 with the corresponding positioning hole 21 and screw it in in the opposite direction to complete the angle locking of the load-bearing rod 2. Finally, install the photovoltaic panel on the installation rod 22. At this time, the photovoltaic panel can perform photoelectric conversion to realize the power generation function. During subsequent seasonal adjustments, the load-bearing rod 2 is rotated to make the slider 31 slide along its bottom. During the sliding process, the slider 31 pushes the soil attached to the bottom of the load-bearing rod 2. At the same time, the guide bar 42 scoops up the soil through the guide slope and guides it into the sand guide trough 4. The soil eventually falls into the sand discharge trough 41 and accumulates. After adjustment, the electromagnet 61 is energized, and the electromagnet 61 generates a magnetic field with the same polarity as the magnetic plate 51. Using the principle of like poles repulsion, the electromagnet 61 will push the magnetic plate 51 down. At this time, the magnetic plate 51 will drive the moving block 5 to move down along the sand discharge trough 41. During the downward movement, the moving block 5 will push the soil accumulated in the sand discharge trough 41 out through the bottom opening of the sand discharge trough 41. Then the electromagnet 61 is de-energized, and the spring 6 uses its rebound force to drive the moving block 5 to return to its original position, so that the sand guide trough 4 and the sand discharge trough 41 are reconnected, ready for the next sand discharge. During the downward movement of the magnet plate 51, the magnet plate 51 engages with the threaded groove 72 on the shaft 71, converting the linear motion into the rotational motion of the shaft 71, which drives the guide plate 73 of the spiral structure to rotate synchronously. The rotation of the guide plate 73 stirs and breaks up the compacted soil, while applying a downward thrust to the soil to accelerate the discharge of the soil. The protective sleeve 53 always covers the threaded groove 72 during the movement to prevent soil from entering and causing jamming. When the soil in the sand discharge trough 41 is severely compacted and difficult to discharge, a water source is connected to the connecting pipe 82 to inject water into the main water supply channel 8. The water flows through the secondary water supply channel 81 and the guide port 54 into the installation groove of the moving block 5, and then permeates evenly into the soil in the sand discharge trough 41 through the permeable plate 52, so that the compacted soil softens and loosens, making it easier to clean and discharge later, and ensuring that there is enough space in the sand discharge trough 41 for subsequent soil to enter.
