Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel mounting frames, and in particular to a photovoltaic panel mounting bracket. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They are mainly composed of photovoltaic cells, tempered glass, EVA, TPT and other materials. The mounting brackets of photovoltaic panels are divided into fixed and movable types. The fixed brackets are generally oriented to the best heat collection angle after measurement, and the movable brackets are generally designed to allow the photovoltaic panels to always face the sun, thereby achieving higher power generation efficiency. Both brackets make the photovoltaic panels in an inclined state.

[0003] Among the existing movable brackets, the single-axis type is the most common, which has a simple structure and low cost. However, since the overall structure is movable, there are fewer support points. In addition, when encountering strong winds, such as strong lateral winds, the photovoltaic panels are set in an inclined state, which increases the windward area of ​​the photovoltaic panels. Under the action of strong winds, the connection strength between the photovoltaic panels and the mounting bracket is affected, and they are also easily overturned and damaged. Summary of the invention

[0004] The object of the present invention is to provide a photovoltaic panel mounting bracket capable of adjusting the tilt state, reducing the windward area, and preventing the photovoltaic panel from being damaged or lifted.

[0006] Preferably, a limiting bracket is provided at the front end of the mounting base plate, the limiting bracket is arranged below the mounting base plate, and a horizontal limiting plate is installed on the first pillar, and the first traction rope pulls the mounting base plate until it abuts against the horizontal limiting plate.

[0007] Preferably, the first pillar is arranged in an inclined shape, and the first pillar is inclined toward one side of the limiting bracket; a supporting platform is provided at the junction of the first pillar and the second pillar, and the guide wheel is provided on the supporting platform.

[0008] Preferably, first sliding grooves are provided on both side surfaces of the first pillar, and both ends of the inner sleeve are clamped in the first sliding grooves to cooperate therewith.

[0009] Preferably, a second slide groove is provided on the inner wall of the outer sleeve, and the direction of the second slide groove is consistent with the length direction of the return spring, and slide plates for inserting into the second slide groove are provided on both sides of the inner sleeve.

[0014] Moreover, when the wind is weak and there is no major risk to the photovoltaic panels and the mounting brackets, the mounting base plate will not flip over, which shows a certain degree of intelligence. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Example 1

[0028] The following is further described in conjunction with specific embodiments. Figure 1-Figure 7 As shown, this embodiment 1 is a photovoltaic panel mounting bracket, including a mounting base plate 1 for supporting the photovoltaic panel, a first support 2 and a second support 3, the first support 2 is connected to the second support 3, the middle part of the mounting base plate 1 is rotatably connected to the top of the first support 2; it also includes a driving mechanism 4 arranged on the first support 2, the driving mechanism 4 includes a first wind drum blade cylinder 41, an inner sleeve 42 and an outer sleeve 43, the inner sleeve 42 is slidably connected to the first support 2, the inner sleeve 42 is arranged in the outer sleeve 43, and the inner sleeve 42 and the outer sleeve 43 are connected. A return spring 44 is connected between the first and second blower blade cylinders 41, the first blower blade cylinder 41 is rotatably connected to the front end of the outer sleeve 43, and a driving gear 411 is provided in the middle of the first blower blade cylinder 41, and a rack 21 is provided on one end surface of the first pillar 2; the wind drives the first blower blade cylinder 41 to rotate, and synchronously drives the outer sleeve 43 to move horizontally relative to the inner sleeve 42, and the return spring 44 is stretched, the driving gear 411 is meshed and connected with the rack 21, and the inner sleeve 42 and the outer sleeve 43 move up along the first pillar 2; the outer sleeve 43 is connected to the first traction rope 5 and the guide Wheel 6, and one end of the first traction rope 5 is connected to the high end of the mounting base plate 1, and the first traction rope 5 pulls the mounting base plate 1 to rotate; specifically, when the present invention is in use, when encountering strong lateral wind, the wind force is large enough to push the first wind drum blade tube 41 and the outer sleeve 43 to move a certain distance relative to the inner sleeve 42, and the moving direction is toward the side of the rack 21. After the reset spring 44 is stretched, the driving gear 411 on the first wind drum blade tube 41 can contact the rack 21 on the first pillar 2 to engage with it, so that the strong wind drives the first wind drum blade tube 41 and the driving gear 411 to rotate, and the first wind drum blade tube 41 and the outer sleeve 43 are an integrated structure, so the outer sleeve 43 and the inner sleeve 42 can climb up along the first pillar 2 as a whole, and the outer sleeve 43 pulls the first traction rope 5 through the guide wheel 6, and one end of the first traction rope 5 pulls one end of the mounting base plate 1 to rotate and descend from an inclined state to a horizontal state, thereby achieving the purpose of lowering the windward surface of the mounting base plate 1 and the photovoltaic panel, protecting the entire bracket and the photovoltaic panel to prevent damage.

[0029] Due to the tilted state, when the mounting base plate 1 and the photovoltaic panel are subjected to strong lateral winds, in theory, all points on their surfaces are affected by wind force, and the wind force is uniform, that is, the forces on both sides of the rotation connection point between the first pillar 2 and the mounting base plate 1 are uniform, which can be regarded as a relatively balanced state, that is, when it is subjected to strong winds, when the first traction rope 5 applies an additional external force to pull, the balance is broken, and the mounting base plate 1 together with the photovoltaic panel flips toward a horizontal state.

[0030] When the external wind force gradually decreases, the reset spring 44 retracts, the connection between the driving gear 411 and the rack 21 is released, and the driving mechanism 4 will slide down along the first pillar 2. Due to the loss of the pulling force of the first traction rope 5, the mounting base 1 will return to the normal inclined working state. Specifically, a torsion spring can be provided at the rotating connection of the mounting base 1 to provide reset power, or the gravity at the front end of the mounting base 1 can be slightly heavier than the rear end to achieve reset.

[0031] When the wind speed and wind force are low, under the pulling force of the return spring 44, the driving gear 411 cannot produce enough displacement to come into contact with the rack 21, and the wind speed at this time cannot have a significant impact on the photovoltaic panel and the bracket.

[0032] Reference Figure 1 and Figure 2 As shown, a limiting bracket 7 is provided at the front end of the mounting base plate 1 in this embodiment, and the limiting bracket 7 is arranged below the mounting base plate 1, and a horizontal limiting plate 8 is installed on the first pillar 2, and the first traction rope 5 pulls the mounting base plate 1 until it abuts against the horizontal limiting plate 8; specifically, when the mounting base plate 1 is reset to an inclined state, the limiting bracket 7 supports it, and cooperates with the rotation connection point of the first pillar 2 and the mounting base plate 1 to form a two-point support, and the horizontal limiting plate 8 prevents the first traction rope 5 from pulling the mounting base plate 1 to rotate excessively when it turns to the horizontal, thereby limiting it and ensuring that it has a better wind shelter angle.

[0033] Reference Figure 1 and Figure 2 As shown, in order to help the outer sleeve 43 and the inner sleeve 42 to move up more easily, the first pillar 2 in this embodiment is arranged in an inclined shape, and the first pillar 2 is inclined toward the side of the limiting bracket 7; a supporting platform 9 is provided at the junction of the first pillar 2 and the second pillar 3, and the guide wheel 6 is provided on the supporting platform 9; specifically, the angle between the horizontal wind direction and the first pillar 2 is an acute angle, and when the outer sleeve 43 and the first wind drum blade tube 41 are subjected to the continuous action of strong winds, the stability of the contact connection between the driving gear 411 and the rack 21 is also better.

[0034] Reference Figure 1 and Figure 4 As shown, in this embodiment, first slide grooves 22 are provided on both side surfaces of the first pillar 2, and both ends of the inner sleeve 42 are clamped in the first slide grooves 22 to cooperate therewith; specifically, the two ends of the inner sleeve 42 are embedded in the first slide grooves 22 like claws, which makes the sliding smoother and prevents large circumferential displacement. In order to reduce the sliding friction force, the claws at both ends of the inner sleeve 42 are round head structures.

[0035] Reference Figure 4As shown, a second slide groove 431 is provided on the inner wall of the outer sleeve 43, and the direction of the second slide groove 431 is consistent with the length direction of the return spring 44, and slide plates 421 for inserting into the second slide groove 431 are provided on both sides of the inner sleeve 42; specifically, because the slide plate 421 is inserted into the second slide groove 431 and can move back and forth relatively, when strong wind drives the first wind drum blade cylinder 41 and the outer sleeve 43 to have an upward force, the outer sleeve 43 can drive the inner sleeve 42 to move up synchronously through the slide plate 421.

[0036] In order to ensure that the mounting base 1 can automatically return to the inclined working state when the wind weakens, a counterweight block 12 is provided at the front end of the mounting base 1, and the counterweight block 12 is close to the rotation connection between the first pillar 2 and the mounting base 1; specifically, because the counterweight block 12 is located at the front end and is slightly heavier, under the action of gravity, the mounting base 1 is flipped as a whole to contact the limit bracket 7.

[0037] Reference Figure 3 and Figure 7 As shown, at least one weight-reducing hole 11 is provided on the mounting base plate 1; specifically, the overall weight of the mounting bracket is reduced, and it helps to improve the heat dissipation problem at the back of the photovoltaic panel.

[0038] Example 2

[0039] Reference Figure 1 and Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that a second blower blade tube 13 is provided at the lower end of the mounting base plate 1, and a second traction rope 14 is wound around the second blower blade tube 13, and one end of the second traction rope 14 is connected to the outer sleeve 43; specifically, in windy weather, the airflow blowing on the lower end of the mounting base plate 1 will have a diversion effect, and the flow rate at the position of the second blower blade tube 13 is faster. When the second blower blade tube 13 is rotated by the wind, the second traction rope 14 will be wound around it to promote the lifting of the outer sleeve 43, assist the first blower blade tube 41 to climb, and help the mounting base plate 1 to tend to a horizontal state.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
