Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket with adjustable locking based on a quadrilateral principle and an adjustment method thereof. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electricity. Through the interaction between photons and electrons, electricity is generated in photovoltaic cells. The purpose of photovoltaic panels is to help people convert solar energy directly into electricity, providing people with clean, renewable energy.

[0003] Taking into account the different angles of sunlight in different seasons, solar photovoltaic panels in the same position need to adjust their angles according to the angle of sunlight. In the existing technology, most of them use a triangular support structure to support the photovoltaic panels. The stability of the triangle is used to achieve the stability of the photovoltaic panel support. At the same time, in order to facilitate adjustment, the lower support rod is mostly composed of a threaded rod and a threaded sleeve. By rotating the threaded rod, the length of the rod formed by the threaded rod and the threaded sleeve is changed, thereby achieving the adjustment of the angle of the photovoltaic panel.

[0004] However, photovoltaic panels are generally installed in open areas or at high places such as roofs. The natural wind generated in these areas is strong, which can easily cause the photovoltaic panels to shake. At this time, the threaded rod or threaded sleeve will produce relative movement under traction. Although the relative movement stroke is extremely small, the long-term relative movement will have an impact on the threaded threads between the two, causing damage to the threaded threads. In severe cases, the rod formed by the threaded rod and the threaded sleeve loses its supporting effect, resulting in a decrease in support and the loss of the ability to adjust the angle of the photovoltaic panel. Summary of the Invention

[0005] The object of the present invention is to provide a photovoltaic bracket with adjustable locking based on the quadrilateral principle and an adjustment method thereof, so as to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A photovoltaic bracket with adjustable locking based on the quadrilateral principle, comprising:

[0008] A supporting column, on which a parallel supporting structure connected to the photovoltaic panel is rotatably mounted;

[0009] a locking structure connecting the parallel support structure and the support column, wherein the locking structure can axially lock the parallel support structure so that the parallel support structure maintains a predetermined tilt angle;

[0010] A driving assembly is connected to the supporting column, and a driving plate is connected to the driving assembly;

[0011] A fitting shaft is rotatably mounted on the parallel support structure, and the fitting shaft cooperates with a plurality of staggered retaining positions and adjusting positions provided on the drive plate to adjust the inclination angle of the parallel support structure;

[0012] A trigger structure is connected to the driving plate and the locking structure. When the engaging shaft is matched with the adjusting position, the trigger structure can enable the locking structure to release the axial locking state of the parallel supporting structure.

[0013] As a further solution of the present invention: the parallel support structure includes an auxiliary support rod and a mounting frame rotatably mounted on the support column, the auxiliary support rod and the mounting frame are parallel, and the auxiliary support rod and the mounting frame are connected at one end away from the support column through a follower rod.

[0014] As a further solution of the present invention: the locking structure includes two sets of locking members fixedly connected to the mounting frame and the rotating shaft of the auxiliary support rod, and the locking members are provided with multiple sets of locking grooves equidistantly around the circumference;

[0015] The locking structure further includes an energy storage structure provided on the support column, the energy storage structure being connected to two sets of lifting members, the lifting members being slidably connected to the guide grooves provided on the support column;

[0016] One end of the lifting member is further provided with a locking portion, and the locking portion cooperates with the locking groove to lock the rotating shafts of the mounting bracket and the auxiliary support rod.

[0017] As a further solution of the present invention: the energy storage structure includes a vertical shaft fixedly mounted on the supporting column, the vertical shaft is slidably connected to the lifting member, and a cylindrical spring is sleeved on the vertical shaft, one end of the cylindrical spring is connected to the end of the vertical shaft, and the other end is connected to the lifting member.

[0018] As a further solution of the present invention: the driving assembly includes a transverse frame detachably connected to the supporting column, a threaded rod is rotatably installed on the transverse frame, a threaded sleeve is provided on the threaded rod and is threadedly connected to the threaded sleeve, the threaded sleeve is connected to the driving plate, and a plurality of support rollers that roll with the transverse frame are rotatably installed on the threaded sleeve.

[0019] As a further solution of the present invention: the driving plate is provided with multiple groups of horizontal grooves with successively varying heights and staggered positions, and two adjacent groups of horizontal grooves are connected by an inclined groove;

[0020] The horizontal groove forms the holding position, and the inclined groove forms the adjusting position.

[0021] As a further solution of the present invention: the trigger structure includes a guide member perpendicular to the vertical axis, a driven sleeve is slidably mounted on the guide member, a hinged rod connected to the lifting member is rotatably mounted on the driven sleeve, and a traction plate is connected to the driven sleeve;

[0022] The trigger structure also includes a connecting frame connected to the drive plate, and an abutment wheel is rotatably installed on one end of the connecting frame away from the drive plate. The abutment wheel cooperates with multiple groups of protrusions provided on the traction plate to separate the locking portion from the locking groove.

[0023] As a further solution of the present invention: a flat surface is formed at one end of the protrusion away from the traction plate, and inclined surfaces are provided at both ends of the flat surface, and the abutment wheel can roll onto the flat surface under the guidance of the inclined surfaces.

[0024] A method for adjusting the angle of a photovoltaic panel using the adjustable locking photovoltaic bracket based on the quadrilateral principle comprises the following steps:

[0025] Step 1: Under the action of the locking structure, the parallel support structure maintains a predetermined tilt angle, which enables the photovoltaic panel to maintain the predetermined tilt angle;

[0026] Step 2: When the tilt angle of the photovoltaic panel needs to be adjusted, the driving assembly is controlled to move. At this time, the driving plate can move relative to the interlocking shaft. When the interlocking shaft moves in the holding position, the tilt angle of the photovoltaic panel does not change, and the trigger structure moves, causing the locking structure to release the axial lock of the parallel support structure;

[0027] Step 3: After the locking structure releases the axial lock on the parallel support structure, the engaging shaft moves to the adjustment position, thereby changing the angle of the parallel support structure;

[0028] Step 4: The engaging shaft moves to another set of holding positions, at which point the trigger structure reverses and causes the locking structure to axially lock the parallel support structure again, thereby completing the angle adjustment of the photovoltaic panel.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] By providing a parallel support structure and a locking structure, the locking portion and the locking groove cooperate to achieve axial locking of the mounting frame and the auxiliary support rod, so that both the mounting frame and the auxiliary support rod can have a supporting effect on the photovoltaic panel, thereby improving the stability of the photovoltaic panel when resisting external natural wind. In addition, compared with the photovoltaic bracket using three-point support in the prior art, by converting the two opposite forces acting on the support column into a torque force, the anti-bending and breaking effect of the support column can be improved, thereby ensuring that the structure of the support column is not damaged.

[0031] By providing a driving assembly, a driving plate and an interlocking shaft, the cooperation of the interlocking shaft and the horizontal groove can generate a supporting force for the movement of the auxiliary support rod, so that the shaking force generated by the photovoltaic panel against the external natural wind can be shared by the auxiliary support rod, the mounting frame and the driving plate, so that the auxiliary support rod, the mounting frame or the driving plate are borne by less force. At this time, the force exerted by the driving plate on the threaded rod in the opposite direction through the threaded sleeve will also be smaller, thereby avoiding the threaded sleeve from moving relative to the threaded rod during the shaking of the photovoltaic panel, causing the threads of the two to be damaged and causing the two to be stuck, thereby improving the support stability of the photovoltaic panel and the stability of adjusting the tilt angle of the photovoltaic panel;

[0032] Through the trigger structure, when the inclination angle of the photovoltaic panel is adjusted, the locking part can first be separated from the locking groove to release the axial locking of the auxiliary support rod and the mounting frame, and then the interlocking shaft cooperates with the inclination groove to change the inclination angle of the photovoltaic panel. When the interlocking shaft moves to another horizontal groove, the locking part can be inserted into the corresponding locking groove again, and the axial locking of the auxiliary support rod and the mounting frame is realized again, ensuring that after the inclination angle of the photovoltaic panel is adjusted, the auxiliary support rod, the mounting frame and the drive plate work together to support the photovoltaic panel.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] See also Figures 1 to 8 In an embodiment of the present invention, a photovoltaic bracket with adjustable locking based on the quadrilateral principle includes: a support column 1, a locking structure, a driving component, an engaging shaft 6 and a trigger structure.

[0045] A parallel support structure connected to the photovoltaic panel is rotatably mounted on the support column 1, and the parallel support structure includes an auxiliary support rod 2 and a mounting frame 3 rotatably mounted on the support column 1. The auxiliary support rod 2 and the mounting frame 3 are parallel, and the auxiliary support rod 2 and the mounting frame 3 are connected at one end away from the support column 1 through a follower rod 4.

[0046] Specifically, the spacing between the rotational connections of the auxiliary support rod 2 and the mounting frame 3 on the support column 1 is equal to the length of the follower rod 4, and the spacing between the rotational connections of the follower rod 4 and the support column 1 on the mounting frame 3 is equal to the length of the auxiliary support rod 2, so that the support column 1, the auxiliary support rod 2, the mounting frame 3 and the follower rod 4 can form a parallelogram structure. Based on this parallelogram structure, in the initial state, when the locking structure locks the rotating shaft of the auxiliary support rod 2 and the mounting frame 3, the mounting frame 3 can support the photovoltaic panel, and at the same time, the force of the photovoltaic panel acting on the follower rod 4 can be supported by the auxiliary support rod 2, so that when the angle of the photovoltaic panel is at a predetermined tilt angle, the auxiliary support rod 2 and the mounting frame 3 both have the effect of supporting the photovoltaic panel, thereby improving the stability of the photovoltaic panel at the predetermined tilt angle.

[0047] It should be noted that in this embodiment, when the photovoltaic panel shakes due to the blowing of external natural wind, the auxiliary support rod 2 and the mounting frame 3 will also be subjected to corresponding forces, and the forces will be converted into torque forces on the support columns 1. Compared with the photovoltaic bracket using three-point support in the prior art, the risk of bending and breaking of the support columns 1 is lower, and the supporting effect of the support columns 1 is improved.

[0048] See also Figure 2 、 Figure 7-Figure 8 The locking structure connects the parallel support structure and the support column 1. The locking structure can axially lock the parallel support structure to maintain a predetermined tilt angle. The locking structure includes two sets of locking members 5 fixedly connected to the mounting frame 3 and the rotating shaft of the auxiliary support rod 2. The locking members 5 are circumferentially and equidistantly provided with multiple sets of locking grooves 501.

[0049] The locking structure further includes an energy storage structure provided on the support column 1 , and two sets of lifting members 20 are connected to the energy storage structure, and the lifting members 20 are slidably connected to the conducting groove 101 provided on the support column 1;

[0050] One end of the lifting member 20 is further provided with a locking portion 2001, and the locking portion 2001 cooperates with the locking groove 501 to lock the rotating shaft of the mounting bracket 3 and the auxiliary support rod 2;

[0051] The energy storage structure includes a vertical shaft 21 fixedly mounted on the support column 1, the vertical shaft 21 is slidably connected to the lifting member 20, and a cylindrical spring 22 is sleeved on the vertical shaft 21, one end of the cylindrical spring 22 is connected to the end of the vertical shaft 21, and the other end is connected to the lifting member 20.

[0052] In the initial state, the cylindrical spring 22 is in a compressed state, so that the two sets of lifting parts 20 tend to move away from each other, so that the two sets of locking parts 2001 on the two sets of lifting parts 20 can be respectively inserted into the locking grooves 501 on the corresponding locking parts 5, so as to achieve axial locking of the mounting frame 3 and the auxiliary support rod 2, so that the mounting frame 3 and the auxiliary support rod 2 both have a supporting effect on the photovoltaic panel, thereby improving the stability of the photovoltaic panel when resisting external natural wind.

[0053] Furthermore, since multiple sets of locking grooves 501 are provided on the locking member 5, when the locking portion 2001 is inserted into different locking grooves 501, the stability of the mounting frame 3 and the auxiliary support rod 2 at different angles can be ensured, thereby making the angles of the mounting frame 3 and the auxiliary support rod 2 adjustable.

[0054] Through the above-mentioned arrangement, with the cooperation of the locking portion 2001 and the locking groove 501, the axial locking of the mounting frame 3 and the auxiliary support rod 2 can be achieved, so that the mounting frame 3 and the auxiliary support rod 2 can both have a supporting effect on the photovoltaic panel, thereby improving the stability of the photovoltaic panel when resisting external natural wind. Compared with the photovoltaic bracket using three-point support in the prior art, by converting the two opposite forces acting on the support column 1 into torque force, the anti-bending and anti-breaking effect of the support column 1 can be improved, thereby ensuring that the structure of the support column 1 is not damaged.

[0055] See also Figure 5~Figure 6 The driving assembly is connected to the supporting column 1, and a driving plate 12 is connected to the driving assembly. The driving assembly includes a transverse frame 7 detachably connected to the supporting column 1, and a threaded rod 9 is rotatably installed on the transverse frame 7. The threaded rod 9 is provided with a threaded sleeve 10 threadedly connected thereto, and the threaded sleeve 10 is connected to the driving plate 12, and a plurality of support rollers 11 that are rollingly matched with the transverse frame 7 are rotatably installed on the threaded sleeve 10, wherein the support rollers 11 can transmit the force exerted on the threaded sleeve 10 to the transverse frame 7, thereby effectively preventing the force exerted on the threaded sleeve 10 from directly acting on the threaded rod 9, causing the threaded rod 9 to bend and deform.

[0056] The same set of photovoltaic panels is supported by two sets of support columns 1, and two sets of corresponding drive assemblies are also provided. The two sets of drive assemblies are connected by a connecting belt 23, and one set of the drive assemblies is connected to a hand wheel 8. By rotating the hand wheel 8, the threaded rod 9 can be driven to rotate, thereby changing the position of the drive plate 12. Specifically, the above-mentioned connecting belt 23 is a chain structure.

[0057] The interlocking shaft 6 is rotatably mounted on the parallel support structure. The interlocking shaft 6 cooperates with multiple sets of staggered retaining positions and adjusting positions provided on the driving plate 12 to adjust the inclination angle of the parallel support structure.

[0058] The driving plate 12 is provided with a plurality of groups of horizontal grooves 1201 with varying heights and staggered positions, and two adjacent groups of horizontal grooves 1201 are connected by an inclined groove 1202;

[0059] The horizontal groove 1201 forms the holding position, and the inclined groove 1202 forms the adjusting position.

[0060] When it is necessary to adjust the inclination angle of the photovoltaic panel, the hand wheel 8 is turned so that the threaded rod 9 connected to the hand wheel 8 can be rotated, and the threaded sleeve 10 threadedly matched with the threaded rod 9 moves along the length direction of the threaded rod 9 to drive the drive plate 12 to move. In the initial state, the interlocking shaft 6 is in one of the sets of horizontal grooves 1201, so that in this state, the interlocking shaft 6 cooperates with the horizontal groove 1201, which has a supporting effect on the auxiliary support rod 2, that is, the shaking force generated by the photovoltaic panel against the external natural wind can be shared by the auxiliary support rod 2, the mounting frame 3 and the drive plate 12, so that the auxiliary support rod 2, the mounting frame 3 or the drive plate 12 are borne by less force, and the upper limit of the support force that can be provided to the photovoltaic panel is also higher.

[0061] When the threaded sleeve 10 moves along the length direction of the threaded rod 9, the engaging shaft 6 can move from one group of horizontal grooves 1201 to another horizontal groove 1201 through the inclined groove 1202, so that the inclination angle of the auxiliary support rod 2 changes, thereby changing the inclination angle of the mounting frame 3 and the photovoltaic panel, thereby achieving the purpose of adjusting the inclination angle of the photovoltaic panel.

[0062] Furthermore, when the interlocking shaft 6 is in one of the horizontal grooves 1201, the threaded rod 9 and the threaded sleeve 10 are self-locking due to the threaded connection, and the threaded sleeve 10 is stable when the threaded rod 9 is in a stationary state, so as to ensure the stability of the fit between the interlocking shaft 6 and the horizontal groove 1201 after the angle of the photovoltaic panel is adjusted.

[0063] Through the above-mentioned arrangement, the cooperation between the interlocking shaft 6 and the horizontal groove 1201 can generate a moving support force for the auxiliary support rod 2, and the shaking force generated by the photovoltaic panel against the external natural wind can be shared by the auxiliary support rod 2, the mounting frame 3 and the driving plate 12, so that the force borne by the auxiliary support rod 2, the mounting frame 3 or the driving plate 12 is smaller. At this time, the force exerted by the driving plate 12 on the threaded rod 9 in the opposite direction through the threaded sleeve 10 will also be smaller, thereby avoiding the threaded sleeve 10 moving relative to the threaded rod 9 during the shaking of the photovoltaic panel, causing the threads of the two to be damaged, causing the two to be stuck, thereby improving the support stability of the photovoltaic panel and the stability of adjusting the tilt angle of the photovoltaic panel.

[0064] See also Figure 7-Figure 8 , the trigger structure is connected to the drive plate 12 and the locking structure, and when the engaging shaft 6 cooperates with the adjustment position, the trigger structure can enable the locking structure to release the axial locking state of the parallel support structure;

[0065] The trigger structure includes a guide member 19 perpendicular to the vertical shaft 21, a driven sleeve 17 is slidably mounted on the guide member 19, a hinge rod 18 connected to the lifting member 20 is rotatably mounted on the driven sleeve 17, and a traction plate 15 is connected to the driven sleeve 17;

[0066] The trigger structure also includes a connecting frame 13 connected to the drive plate 12, and an abutment wheel 14 is rotatably installed on the end of the connecting frame 13 away from the drive plate 12. The abutment wheel 14 cooperates with multiple groups of protrusions 16 provided on the traction plate 15 to separate the locking portion 2001 from the locking groove 501, wherein a flat surface 1602 is formed on the end of the protrusion 16 facing away from the traction plate 15, and inclined surfaces 1601 are provided at both ends of the flat surface 1602. The abutment wheel 14 can roll onto the flat surface 1602 under the guidance of the inclined surfaces 1601.

[0067] In the initial state, the cylindrical spring 22 is in a compressed state, so that the locking portion 2001 can be inserted into the locking groove 501 to lock the rotating shaft of the auxiliary support rod 2 and the mounting bracket 3. When the threaded rod 9 rotates and drives the driving plate 12 to move through the threaded sleeve 10, the engaging shaft 6 will first move in the horizontal groove 1201. At this time, the driving plate 12 will also drive the abutment wheel 14 to move through the connecting frame 13, so that the abutment wheel 14 can move toward the inclined surface 1601 and move to abut against the flat surface 1602 by cooperating with the inclined surface 1601, so that the traction plate 15 can drive the driven sleeve plate 17 to move away from the guide member 19. At this time, driven by the hinged rod 18, the two sets of lifting parts 20 will move close to each other until the locking portion 2001 is separated from the locking groove 501. So that the axial locking of the rotating shaft of the auxiliary support rod 2 and the mounting frame 3 is released, and at this time the interlocking shaft 6 just moves to the end of the horizontal groove 1201, and then the interlocking shaft 6 will move along the inclined groove 1202 connected to the horizontal groove 1201 to change the deflection angle of the auxiliary support rod 2 and the mounting frame 3, and then the interlocking shaft 6 will move to another horizontal groove 1201, and at this time the abutment wheel 14 will move from the flat surface 1602 and the other inclined surface 1601 to fit with the traction plate 15. During this process, the cylindrical spring 22 releases its elastic potential energy, and the locking part 2001 can be inserted into the corresponding locking groove 501, thereby realizing the locking of the rotating shaft of the auxiliary support rod 2 and the mounting frame 3, and ensuring that in this state, the auxiliary support rod 2, the mounting frame 3 and the drive plate 12 all have an effect on the photovoltaic panel.

[0068] Through the above-mentioned arrangement, when adjusting the inclination angle of the photovoltaic panel, the locking portion 2001 can first be separated from the locking groove 501 to release the axial locking of the auxiliary support rod 2 and the mounting frame 3, and then the interlocking shaft 6 cooperates with the inclination groove 1202 to change the inclination angle of the photovoltaic panel, and when the interlocking shaft 6 moves to another horizontal groove 1201, the locking portion 2001 can be inserted into the corresponding locking groove 501 again, and the axial locking of the auxiliary support rod 2 and the mounting frame 3 is realized again, ensuring that after the inclination angle of the photovoltaic panel is adjusted, the auxiliary support rod 2, the mounting frame 3 and the drive plate 12 work together to support the photovoltaic panel.

[0069] As an embodiment of the present invention, a method for adjusting the angle of a photovoltaic panel using the adjustable locking photovoltaic bracket based on the quadrilateral principle is also proposed, comprising the following steps:

[0070] Step 1: Under the action of the locking structure, the parallel support structure maintains a predetermined tilt angle, which enables the photovoltaic panel to maintain the predetermined tilt angle;

[0071] Step 2: When the tilt angle of the photovoltaic panel needs to be adjusted, the driving assembly is controlled to move. At this time, the driving plate 12 can move relative to the fitting shaft 6. When the fitting shaft 6 moves in the holding position, the tilt angle of the photovoltaic panel does not change, and the trigger structure moves, causing the locking structure to release the axial lock of the parallel support structure;

[0072] Step 3: After the locking structure releases the axial lock on the parallel support structure, the engaging shaft 6 moves to the adjustment position, thereby changing the angle of the parallel support structure;

[0073] Step 4: The engaging shaft 6 moves to another set of holding positions, at which time the trigger structure reverses and causes the locking structure to axially lock the parallel support structure again, thereby completing the angle adjustment of the photovoltaic panel.
