Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and specifically relates to a photovoltaic bracket facilitating angle adjustment. Background Art

[0002] Photovoltaic is short for solar photovoltaic power generation system, which facilitates people's utilization of green energy. With people's emphasis on energy conservation and emission reduction, solar products are more and more widely used. As a renewable resource, solar energy is more and more popular among people. The solar photovoltaic system is a facility that converts solar energy into direct current electricity by using the photovoltaic effect of photovoltaic semiconductor materials. The core of the photovoltaic facility is the solar panel. The semiconductor materials used for the solar panel to generate electricity mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, etc. In recent years, since various countries have been actively promoting the application of renewable energy, the development of the photovoltaic industry has been very rapid. During the process of photovoltaic power generation, it is necessary to use a photovoltaic bracket to fixedly install the solar panel, so as to facilitate the full absorption and conversion of solar energy. When the photovoltaic bracket fixedly installs the photovoltaic panel, it usually adjusts to an angle suitable for the photovoltaic panel to absorb the sun. However, the existing photovoltaic bracket is difficult to ensure its stability when the angle that the photovoltaic panel needs to adjust is greater than 180° to absorb solar energy on the other side. Therefore, we propose a photovoltaic bracket facilitating angle adjustment. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a photovoltaic bracket facilitating angle adjustment, including: A first side frame, with a roller column arranged on one side of the first side frame; One end of the roller column away from the first side frame is rotationally connected to a second side frame through a rotating bolt. A motor is fixedly connected to the side of the second side frame away from the roller column. Inner clamping devices are fixedly connected to positions near both ends on the outer side of the roller column; A water removal device, which is used for absorbent wiping treatment of the accumulated water on the surface of the photovoltaic panel; One side of the first side frame is rotationally connected to one end of the roller column through a rotating bolt. The driving shaft of the motor penetrates the first side frame and is fixedly connected to one end of the roller column; Wherein, the inner clamping device includes: A side support plate, with a square sliding hole arranged on its outer surface; A square clamping plate, with a T-shaped slider arranged on one side of the square clamping plate; The inner wall of the square sliding hole is slidably connected to the outer side of the T-shaped slider. One side of the T-shaped slider is fixedly connected to one side of the square clamping plate. There are multiple square clamping plates, and the multiple square clamping plates are symmetrically distributed on one side of the side support plate respectively; The bottom of the side support plate is fixedly connected to the outer surface of the roller column; A square connecting plate is fixedly connected to the outer surface of the roller column. An electric slide rail is fixedly connected to the top of the square connecting plate. A top-mounted slide plate is slidably connected to the top of the electric slide rail; The top of the top-mounted slide plate is fixedly connected to the bottom of the water removal device. A plurality of top-mounted slide plates are provided, and the plurality of top-mounted slide plates are symmetrically distributed on the top of the electric slide rail respectively. A plurality of water removal devices are provided, and the plurality of water removal devices are symmetrically distributed on the top-mounted slide plates respectively; A square rubber pad is fixedly connected to one side of the square clamping plate. By providing a square rubber pad made of an elastic material on one side of the square clamping plate to elastically contact and squeeze the photovoltaic panel, it is prevented that the square clamping plate is difficult to control the force when rigidly clamping the photovoltaic panel and causing damage to the photovoltaic panel. An I-shaped slide plate is penetrated and slidably connected to one side of the square clamping plate. By providing an I-shaped slide plate between the bottom of the square rubber pad and the threaded torsion rod to support the bottom of the inserted photovoltaic panel, it is prevented that the photovoltaic panel directly contacts the outer surface of the threaded torsion rod when inserted, resulting in scratching of the threaded surface of the threaded torsion rod on the photovoltaic panel during subsequent clamping. By providing an I-shaped slide plate above the threaded torsion rod to cover and resist the area above the threaded torsion rod, it is prevented that sundries driven during the disassembly and installation of the photovoltaic panel directly fall on the threaded torsion rod and affect the thread fit. A threaded torsion rod is penetrated and threadedly connected to one side of the square clamping plate. By rotating the threaded torsion rod, two symmetrically arranged square rubber pads are driven to squeeze and clamp the two sides of the photovoltaic panel, preventing the photovoltaic panel from being loosened from the photovoltaic bracket when the angle to be adjusted is greater than 180° and the other side is used for solar energy absorption; The I-shaped slide plate is arranged at a position on one side of the square clamping plate at the bottom of the square rubber pad. The threaded torsion rod is arranged at a position on one side of the square clamping plate at the bottom of the I-shaped slide plate.

[0004] Furthermore, the water removal device includes a square sponge, which absorbs residual water droplets on the surface of the photovoltaic panel after pre-scraping when the square sponge moves with the side square plates, so as to prevent the moisture on the surface of the photovoltaic panel from being difficult to dissipate for a long time, causing the photovoltaic panel to be too wet and affecting the solar energy absorption effect. The square sponge is fixedly connected to the side square plates on both sides. When the side square plates move, the surface of the photovoltaic panel is pre-scraped and drained first to prevent too much water from accumulating on the photovoltaic panel, which makes it difficult for the square sponge to effectively absorb the accumulated water covering a large area. When the two symmetrically arranged side square plates move toward each other, the square sponge is compressed and drained, so as to prevent the square sponge from being filled with water after long-term use and reaching absorption saturation, making it difficult to absorb water. A ventilation and drying mechanism is penetrated and slidably connected to one side of the side square plate, a circular through hole is opened on the side of the square sponge close to the side square plate, and a return spring is fixedly connected to the inner wall of the circular through hole, and the square sponge is pushed to expand and recover through the stretching force of the return spring, so as to prevent the square sponge from gradually losing its elastic restoring force due to excessive squeezing force for a long time and affecting the subsequent water absorption effect, the bottom of the side square plate is fixedly connected to the top of the top slide, and one side of the side square plate is fixedly connected to one end of the return spring, a plurality of the circular through holes are provided, and the plurality of the circular through holes are distributed on one side of the square sponge, a plurality of the ventilation and drying mechanisms are provided, and the plurality of the ventilation and drying mechanisms are distributed inside the circular through holes.

[0005] Furthermore, the ventilation and drying mechanism comprises an inner air-through pipe, and an annular sleeve block is sleeved on the outer side of the inner air-through pipe and fixedly connected thereto; the annular sleeve block is arranged inside the circular through hole to resist and limit the side square plate so that the reset spring is never in a fully contracted state, thereby preventing excessive pressure on the reset spring when the two side square plates move toward each other, thereby preventing the reset spring from being in a fully contracted state for a long time and gradually losing its elastic restoring force and becoming difficult to use; small ventilation holes are arranged on the outer side of the inner air-through pipe, and circular blocks are fixedly connected at both ends of the inner air-through pipe; circular blocks are arranged at both ends of the inner air-through pipe to resist and limit the side square plate moving back toward the outside to prevent it from being affected by electric The side square plate of the slide rail electric control fails to accurately control the distance, resulting in excessive stretching and damage of the square sponge. A docking circular hole connected to the inner air pipe is provided on one side of the circular stopper. By providing the ventilation holes and the docking circular holes, the square sponge is accelerated to dry by promoting the reciprocating flow of gas during compression and expansion, thereby preventing the square sponge from being squeezed and accumulating a small amount of residual water inside, which is difficult to be discharged, causing the square sponge to continue to be damp and affecting the water absorption effect. One end of the inner air pipe passes through the side square plate and is slidably connected to the side square plate. A plurality of ventilation holes are provided, and the plurality of ventilation holes are distributed on the outer surface of the inner air pipe on both sides of the annular sleeve.

[0006] The present invention provides a photovoltaic bracket that is easy to adjust the angle. It has the following beneficial effects: 1. The photovoltaic bracket facilitating angle adjustment squeezes and clamps both sides of the photovoltaic panel by rotating the threaded torsion rod to drive two symmetrically arranged square rubber pads, preventing the photovoltaic panel from being unclamped and detached from the photovoltaic bracket when the angle to be adjusted is greater than 180° for solar absorption on the other side. When the square sponge moves together with the side-mounted square plate, it absorbs the residual water droplets after the pre-scraping treatment on the surface of the photovoltaic panel, preventing the water on the surface of the photovoltaic panel from being difficult to disperse for a long time, which may cause the photovoltaic panel to be too damp and affect the solar absorption effect. By opening ventilation holes and docking circular holes, the reciprocating flow of gas is promoted when the square sponge compresses and expands, accelerating the drying of the square sponge, preventing a small amount of residual water from remaining in the square sponge after being squeezed and being difficult to be discharged, resulting in the continuous dampness of the square sponge and affecting the water absorption effect.

[0007] 2. The photovoltaic bracket facilitating angle adjustment is provided with an inner clamping device. By rotating the threaded torsion rod to drive two symmetrically arranged square rubber pads to squeeze and clamp both sides of the photovoltaic panel, it prevents the photovoltaic panel from being unclamped and detached from the photovoltaic bracket when the angle to be adjusted is greater than 180° for solar absorption on the other side. By setting square rubber pads made of elastic material on one side of the square clamping plate to elastically contact and squeeze the photovoltaic panel, it prevents the square clamping plate from being difficult to control the force when rigidly clamping the photovoltaic panel and causing damage to the photovoltaic panel. By setting an I-shaped sliding plate between the bottom of the square rubber pad and the threaded torsion rod to support the bottom of the inserted photovoltaic panel, it prevents the photovoltaic panel from directly contacting the outer surface of the threaded torsion rod when inserted, resulting in scratching of the threaded surface of the threaded torsion rod on the photovoltaic panel during subsequent clamping. By setting an I-shaped sliding plate above the threaded torsion rod to cover and resist the area above the threaded torsion rod, it prevents the sundries driven during the disassembly and installation of the photovoltaic panel from directly falling on the threaded torsion rod and affecting the thread fit.

[0008] 3. The photovoltaic bracket facilitating angle adjustment is provided with a water removal device. When the side-mounted square plate moves, it first pre-scrapes and drains the surface of the photovoltaic panel, preventing a large amount of accumulated water on the photovoltaic panel from making it difficult for the square sponge to effectively absorb the accumulated water covering a large area. When the square sponge moves together with the side-mounted square plate, it absorbs the residual water droplets after the pre-scraping treatment on the surface of the photovoltaic panel, preventing the water on the surface of the photovoltaic panel from being difficult to disperse for a long time, which may cause the photovoltaic panel to be too damp and affect the solar absorption effect. When two symmetrically arranged side-mounted square plates move towards each other, they compress and drain the square sponge, preventing the inside of the square sponge from being filled with water and reaching the absorption saturation after long-term use, making it difficult to absorb water again. The extension force of the return spring is used to push the square sponge to expand and recover, preventing the square sponge from gradually losing its elastic recovery force under the influence of excessive extrusion force for a long time and affecting the subsequent water absorption effect.

[0009] 4. The photovoltaic bracket facilitating angle adjustment is provided with a ventilation and drying mechanism. By opening ventilation holes and docking round holes, the reciprocating flow of gas is promoted during the compression and expansion of the square sponge to accelerate the drying of the square sponge, preventing a small amount of residual water from remaining inside the square sponge after being squeezed and being difficult to discharge, resulting in the continuous dampness of the square sponge and affecting the water absorption effect. By arranging an annular sleeve block inside the circular through-hole to resist and limit the side square plate, the return spring is always not in a fully contracted state, preventing the pressure exerted on the return spring when the two side square plates move towards each other from being too large, causing the return spring to be in a fully contracted state for a long time and gradually losing its elastic resilience and being difficult to use. By arranging circular stoppers at both ends of the inner through-tube to resist and limit the side square plate moving back outwards, preventing the side square plate controlled by the electric slide rail from failing to accurately control the distance and causing damage to the square sponge due to excessive stretching.

[0014] Please refer to Figures 1-8 The present invention provides a photovoltaic bracket convenient for angle adjustment: The water removal device 6 includes a square sponge 601. Both sides of the square sponge 601 are fixedly connected with side square plates 602. One side of the side square plate 602 penetrates and is slidably connected with a ventilation and drying mechanism 603. A circular through hole 604 is opened on one side of the square sponge 601 close to the side square plate 602. The inner wall of the circular through hole 604 is fixedly connected with a return spring 605. The bottom of the side square plate 602 is fixedly connected with the top of the top slide plate 9. One side of the side square plate 602 is fixedly connected with one end of the return spring 605. There are multiple circular through holes 604, and the multiple circular through holes 604 are distributed on one side of the square sponge 601. There are multiple ventilation and drying mechanisms 603, and the multiple ventilation and drying mechanisms 603 are distributed inside the circular through holes 604; The ventilation and drying mechanism 603 includes an inner through-tube 6031. An annular sleeve block 6032 is sleeved and fixedly connected to the outer side of the inner through-tube 6031. Ventilation holes 6033 are formed in the outer side of the inner through-tube 6031. Circular stoppers 6034 are fixedly connected to both ends of the inner through-tube 6031. Docking round holes 6035 communicating with the inner through-tube 6031 are formed in one side of the circular stoppers 6034. One end of the inner through-tube 6031 penetrates through the side square plate 602 and is slidably connected to the side square plate 602. There are multiple ventilation holes 6033, and the multiple ventilation holes 6033 are distributed at positions on the outer surface of the inner through-tube 6031 on both sides of the annular sleeve block 6032. During use, when there is water accumulation on the photovoltaic panel, the top slide plate 9 is driven by the electric slide rail 8 to drive the side square plate 602 and the square sponge 601 to move together. When the side square plate 602 moves, it first performs a pre-scraping and drainage treatment on the surface of the photovoltaic panel. When the square sponge 601 moves together with the side square plate 602, it absorbs the residual water droplets after the pre-scraping treatment on the surface of the photovoltaic panel. After the square sponge 601 absorbs water multiple times, the top slide plate 9 is driven by the electric slide rail 8 to drive the two symmetrically arranged side square plates 602 to move towards each other. When the two symmetrically arranged side square plates 602 move towards each other, they compress the square sponge 601 to drain water. When the two side square plates 602 move towards each other, they also compress the return spring 605. After the square sponge 601 is compressed, the driving of the electric slide rail 8 on the top slide plate 9 is removed. At this time, the return spring 605 pushes the side square plates 602 at both ends to move to both sides by the stretching force and pulls the square sponge 601 to expand and recover. By the stretching force of the return spring 605, the square sponge 601 is pushed to expand and recover. When the two side square plates 602 move, they both slide on the inner through-tube 6031. When the two side square plates 602 move towards each other, they compress the square sponge 601. At the same time, a part of the gas and water inside the square sponge 601 will be squeezed into the inner through-tube 6031 through the ventilation holes 6033 and discharged from the docking round holes 6035 of the circular stoppers 6034 along both ends. When the square sponge 601 expands and recovers, it also inhales external air into the square sponge 601 through the docking round holes 6035 and the ventilation holes 6033. By providing the ventilation holes 6033 and the docking round holes 6035, the square sponge 601 promotes the reciprocating flow of gas during compression and expansion to accelerate the drying of the square sponge 601. At the same time, when the two side square plates 602 move towards each other, they will gradually approach the annular sleeve block 6032, contact the annular sleeve block 6032 and stop. By providing the annular sleeve block 6032 inside the circular through-hole 604 to resist and limit the side square plate 602, the return spring 605 will never be in a completely contracted state. By providing the circular stoppers 6034 at both ends of the inner through-tube 6031 to resist and limit the side square plate 602 moving back outwards.

[0015] When the present invention is in operation, the photovoltaic panel is inserted into the inner clamping device 5, and the inner clamping device 5 clamps it in an elastic contact manner. After clamping, the motor 4 is started to drive the roller 2 to rotate. When the roller 2 rotates, it drives the inner clamping device 5 and the clamped photovoltaic panel to rotate together to adjust the angle of the photovoltaic panel. When there is water accumulation on the photovoltaic panel, the electric slide rail 8 is used to drive the top-mounted slide plate 9 to move, driving the water removal device 6 at the top to perform absorption water treatment on the surface of the photovoltaic panel. When installing the photovoltaic panel, the photovoltaic panel is inserted onto the I-shaped slide plate 506 between two symmetrically arranged square rubber pads 505. The threaded torsion rod 507 is rotated, and through threaded cooperation, the two symmetrically arranged square clamping plates 503 move towards each other under the sliding limit of the T-shaped slider 504 and the square sliding hole 502. When the square clamping plate 503 moves, it drives the square rubber pad 505 on one side to move together. By rotating the threaded torsion rod 507, the two symmetrically arranged square rubber pads 505 are driven to squeeze and clamp the two sides of the photovoltaic panel. By arranging a square rubber pad 505 made of elastic material on one side of the square clamping plate 503 to elastically contact and squeeze and clamp the photovoltaic panel. By arranging an I-shaped slide plate 506 between the bottom of the square rubber pad 505 and the threaded torsion rod 507 to support the inserted photovoltaic panel at the bottom. By arranging an I-shaped slide plate 506 above the threaded torsion rod 507 to cover and resist the area above the threaded torsion rod 507. When there is water accumulation on the photovoltaic panel, the electric slide rail 8 is used to drive the top-mounted slide plate 9 to drive the side-mounted square plate 602 and the square sponge 601 to move together. When the side-mounted square plate 602 moves, it first performs pre-scraping and drainage treatment on the surface of the photovoltaic panel. When the square sponge 601 moves together with the side-mounted square plate 602, it absorbs the remaining water droplets after the pre-scraping treatment on the surface of the photovoltaic panel. After the square sponge 601 absorbs water multiple times, the electric slide rail 8 is used to drive the top-mounted slide plate 9 to drive the two symmetrically arranged side-mounted square plates 602 to move towards each other. When the two symmetrically arranged side-mounted square plates 602 move towards each other, they compress the square sponge 601 for drainage. When the two side-mounted square plates 602 move towards each other, they also compress the return spring 605. After the square sponge 601 is compressed, the driving of the electric slide rail 8 on the top-mounted slide plate 9 is removed. At this time, the return spring 605 uses the stretching force to push the side-mounted square plates 602 at both ends to move to both sides and pull the square sponge 601 to expand and recover. By the stretching force of the return spring 605, the square sponge 601 is pushed to expand and recover. When the two side-mounted square plates 602 move, they both slide on the inner through-air pipe 6031. When the two side-mounted square plates 602 move towards each other, they compress the square sponge 601. At the same time, a part of the gas and water inside the square sponge 601 will be squeezed through the ventilation small holes 6033 into the inner through-air pipe 6031 and discharged from the docking round holes 6035 of the circular stopper 6034 at both ends. When the square sponge 601 expands and recovers, it will also inhale external air into the square sponge 601 through the docking round holes 6035 and the ventilation small holes 6033.By providing vent holes 6033 and docking round holes 6035, the square sponge 601 promotes the reciprocating flow of gas during compression and expansion to accelerate the drying of the square sponge 601. At the same time, when the two side plates 602 move towards each other, they will gradually approach the annular sleeve block 6032, contact it and stop. By arranging the annular sleeve block 6032 inside the circular through hole 604, the side plates 602 are resisted and limited, so that the return spring 605 will never be in a fully contracted state. By providing circular stoppers 6034 at both ends of the inner through-tube 6031, the side plates 602 moving back outward are resisted and limited.
