Description

Technical Field

[0001] The utility model belongs to the technical field of solar racks, and in particular relates to an adjustable solar rack for a movable house. Background Art

[0002] Solar power supply technology is a photovoltaic power generation technology that converts solar energy into electrical energy and transmits it to electrical equipment. With the continuous development of solar energy-related supporting technologies, solar power supply devices have been widely used in various industries. Traditional solar insulation power supply modules are often fixed to the support frame through multiple sets of bolts, and the inclination angle of the support frame is often fixed. Therefore, it is not convenient to tilt the solar insulation power supply module at an independent angle, which greatly affects the power generation efficiency of the solar insulation power supply module.

[0003] To this end, the invention patent application with patent application number 201910264027.4 discloses a solar photovoltaic bracket that is easy to adjust the angle. By rotating the screw, the movable support rod can be moved back and forth, thereby adjusting the inclination angle of the second support rod, and the angle of the bracket can be quickly adjusted. Although this structure can achieve angle adjustment; it mainly relies on the self-locking characteristics of the screw to fix the position, and the position of the screw is easily eroded by rainwater, resulting in excessive resistance when used again, or even stuck. At the same time, the length of the screw is fixed. After adjustment, the screw will be exposed to the outside and more susceptible to erosion by rainwater.

[0004] At the same time, the movable support rod mainly plays the role of adjusting support, but the cooperation between the roller and the slide groove results in poor connection strength; therefore, it is also provided with a corresponding gas spring to stably support and buffer the second support rod to ensure the stability of the bracket.

[0008] The driving mechanism includes a driving gear and a driving rod; the positioning pins are fixedly connected to racks, the driving gear is located between the two racks and meshes with the two racks; the driving rod is rotatably connected to the connecting frame, and the driving gear is fixedly connected to the driving rod; after the two positioning pins are moved relative to each other by rotating the driving rod, the driving rod is pushed to drive the connecting frame to move along the fixed frame.

[0009] The driving mechanism also includes a return spring; each positioning pin is connected to a return spring; and both ends of the return spring are fixedly connected to the positioning pin and the connecting frame respectively.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figure 1-10 As shown, an adjustable solar rack for a portable home includes a fixed frame 1 and a photovoltaic mounting panel 2. One end of the photovoltaic mounting panel 2 is hingedly connected to the upper end of the fixed frame 1. The photovoltaic panel is fixedly mounted on the photovoltaic mounting panel 2, specifically by bolting. The fixed frame 1 is also bolted to the portable home.

[0028] A connecting frame 3 is slidably connected to the fixed frame 1; the photovoltaic mounting panel 2 and the connecting frame 3 are connected by a connecting rod 4, and the two ends of the connecting rod 4 are hinged to the connecting frame 3 and the photovoltaic mounting panel 2 respectively; the above structure provides stable adjustment for the photovoltaic mounting panel 2.

[0029] Positioning pins 5 are slidably connected to both ends of the connecting frame 3, and corresponding positioning through holes are provided on the fixed frame 1; the connecting frame 3 is connected to a driving mechanism, which drives the two positioning pins 5 to move relative to or away from each other.

[0030] This adjustment utilizes dual positioning pins 5 for secure positioning. Furthermore, positioning holes can be positioned at varying intervals as needed, allowing for quick and easy adjustment to the desired tilt angle. For example, when the positioning pin 5 is inserted into the first positioning hole, the photovoltaic mounting panel 2 tilts at a 30-degree angle; when inserted into the second positioning hole, the tilt angle is 35 degrees.

[0031] During adjustment, the two positioning pins 5 are driven to move relative to each other by the driving mechanism, and the distance between the two positioning pins 5 is shortened, so that they are moved out of the corresponding positioning through holes; then the connecting frame 3 is pushed to move by the driving mechanism until it moves to the positioning through hole corresponding to the required adjustment angle; finally, the two positioning pins 5 are driven to move in opposite directions by the driving mechanism, and the distance between the two positioning pins 5 is increased, so that they are moved deeper into the corresponding positioning through holes.

[0032] During the movement of the connecting frame 3, the connecting rod 4 can drive the photovoltaic mounting panel 2 to change its angle. The connecting rod 4 is only connected to the two by a hinged manner. The connecting frame 3 is fixed in position by the positioning pins 5, thereby ensuring the stability of the overall adjustment structure.

[0033] The drive mechanism further includes a drive gear 6 and a drive rod 7. Each positioning pin 5 is fixedly connected to a rack 8. The drive gear 6 is positioned between and meshes with two racks 8. The drive rod 7 is rotationally connected to the connecting frame 3, meaning that the drive rod 7 can only rotate and cannot move axially. The drive gear 6 is fixedly connected to the drive rod 7.

[0034] During use, the drive rod 7 is rotated to cause the gear to mesh with the two racks 8, driving the two positioning pins 5 to move relative to each other until they are removed from the positioning holes. The drive rod 7 is then pushed to cause the connecting frame 3 to move along the fixed frame 1 for adjustment. After reaching the desired adjustment position, the drive rod 7 is rotated in the opposite direction to cause the gear to mesh with the two racks 8, driving the two positioning pins 5 to move away from each other until they are extended from the positioning holes.

[0035] Furthermore, the drive mechanism includes a return spring 9; each locating pin 5 is connected to a return spring 9; its ends are fixedly connected to the locating pin 5 and the connecting frame 3. When the drive rod 7 is rotated to cause the gear to mesh with the two racks 8 and drive the two locating pins 5 relative to each other, the two return springs 9 are compressed to generate elastic potential energy. When the desired adjustment position is reached, the external force is removed, and the two return springs 9 release the elastic potential energy, pushing the locating pins 5 out of the locating through-holes, eliminating the need for reverse rotation.

[0036] Furthermore, in order to avoid the driving rod 7 being too long and thus unable to be effectively blocked by the photovoltaic mounting panel 2; therefore, the driving mechanism also includes a movable rod 10, which is rotatably connected to the fixed frame 1 and can move back and forth along the fixed frame 1; the end of the movable rod 10 is clamped with the front end of the driving rod 7 through a connecting assembly.

[0037] During adjustment, the movable rod 10 is pulled out and engaged with the drive rod 7, thereby rotating and moving the drive rod 7. After adjustment, the engagement is released and the movable rod 10 is pushed back. This structure shortens the drive rod 7 and allows the movable rod 10 to be pushed back after adjustment, shielded by the photovoltaic mounting panel 2 and reducing erosion by rainwater.

[0038] Furthermore, the connection assembly includes a connection disk 11 and a clamping disk 12. The connection disk 11 is fixedly connected to the front end of the driving rod 7. The connection disk 11 is provided with a connection slot 13. The clamping disk 12 is sleeved outside the driving rod 7 and fixedly connected to the end of the movable rod 10. The clamping disk 12 is provided with a latch 14 that cooperates with the connection slot 13. After the latch 14 is connected to the connection slot 13, it can limit the forward and backward movement of the movable rod 10. The connection slot 13 has an insertion portion and a clamping portion 131. The head 140 of the latch 14 is a large diameter portion, and its rod portion 141 is a small diameter portion. The head 140 of the latch 14 can be inserted into the connection slot 13 through the plug-in portion 130, and the size of the clamping portion 131 is slightly larger than the rod portion 141 and smaller than the head 140, thereby achieving a clamping connection between the two.

[0039] During adjustment, the movable rod 10 is pulled out so that the head 140 of the bayonet 14 can pass through the plug-in portion 130 and penetrate into the connecting slot 13; then the movable rod 10 is rotated to drive the driving rod 7 to rotate, so that the two positioning pins 5 are moved out of the positioning through holes; at the same time, during the rotation of the movable rod 10, the head 140 of the bayonet 14 moves to the engaging portion 131; at this time, due to the obstruction of the engaging portion 131, the movable rod 10 can be pushed and driven to move, thereby realizing the sliding of the connecting frame 3.

[0040] After adjustment, the movable rod 10 is rotated in the opposite direction to move the head 140 of the bayonet 14 to the insertion portion 130 ; then the movable rod 10 is pushed to remove the head 140 of the bayonet 14 from the insertion portion 130 and push the movable rod 10 back.

[0041] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
