Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

The easily detachable rotating structure is shown in fig. 1 and comprises a main beam 4, a base 2 and at least two rotating pieces 3, wherein each rotating piece 3 is rotatably arranged on the base 2 and detachably arranged; each rotating part 3 is arranged on the periphery of a main beam 4, and the main beam 4 is arranged on the base 2 through each rotating part 3; the rotor 3 can be detached directly from the main beam 4 after being detached from the base 2. This scheme sets up through the aforesaid, can prevent to rotate under the prerequisite of 3 slippage bases 2, has reduced partial part, makes holistic structure simple clean and tidy more, when maintaining, can realize rotating the installation or the separation of piece 3 and girder 4 fast, makes things convenient for staff or owner's operation.

The number of commentaries on classics piece 3 in this scheme will be greater than one, and traditional mode just leads to rotating 3 and the unable smooth separation of girder 4 because only one rotates piece 3, sets up two rotation pieces 3 in this embodiment, and girder 4 wears to establish and is fixed in two rotation pieces 3 between and rotates 3 synchronous rotations along with two.

The shape of the rotatable member 3 is such that it can rotate within the base 2 and has an end face for gripping the main beam 4. The shape of the device can be various, and the device is in a semicircular cylinder shape in the embodiment. Meanwhile, the main beam 4 is arranged between the two rotating members 3 in the embodiment, when the two rotating members 3 are the same in shape and are all semicircular cylinders, the main beam 4 still can move in the radial direction between the two rotating members, so that the solar panel on the main beam 4 shakes, and the device is not stable enough. Therefore, in the present embodiment, the two rotating members 3 are provided with positioning grooves for limiting the radial movement of the main beams 4 corresponding to the main beams 4. After the main beam 4 is installed on the rotating part 3 through the positioning groove, the main beam 4 can not move radially, and the whole structure is more stable.

Preferably, since the main beam 4 in this embodiment is a hollow rectangular tube, the positioning groove is a rectangular groove 312 conforming to the shape of the main beam 4, and after the main beam 4 is installed with the two rotating members 3, the main beam 4 is clamped in the two rectangular grooves 312 and rotates in the base 2 along with the two rotating members 3.

Base 2 of this embodiment is the cavity annular, rotates piece 3 and is used for setting up in 4 peripheries of girder, rotates piece 3 along base 2's axial cartridge on base 2, rotates piece 3 and withdraws from base 2 axial withdraw from base 2, after separating with base 2, can separate with girder 4 along base 2's radial. With this arrangement, the rotor 3 can be mounted on the base 2 only along one direction of the axis of the base 2 itself, and after the mounting is completed, the restricting portion 311 abuts against the side wall of the base 2 to restrict the rotor 3 from moving further along the axis of the base 2, and at this time, the rotor 3 can only be withdrawn from the base 2 in the original direction (see fig. 2). In order to prevent when girder 4 rotates the regulation, the condition that the piece 3 that takes place to rotate and withdraw from along former installation direction, this embodiment still is equipped with the limit structure 5 that is used for preventing to rotate piece 3 and takes place axial displacement at girder 4, limit structure 5 sets up the dog 51 in two relative terminal surfaces of girder 4 including fixed, two dogs 51 correspond two respectively and rotate 3 settings, girder 4 wears to establish and is fixed in two and rotates 3 when middle, two dogs 51 butt restriction portion 311 takes place axial displacement with the restriction rotation piece 3 respectively. With this arrangement, after the main beam 4 is mounted and erected, the stoppers 51 abut against the restricting portions 311 of the two rotation members 3, respectively, so that the rotation members 3 do not retreat in the original mounting direction.

Preferably, the stopper 51 has an L-shaped cross section, and one surface of the stopper 51 abuts against the restricting portion 311 and the other surface is fixedly connected to the main beam 4. This design setting makes dog 51 can be fine enough to support by restriction portion 311, and the removal of piece 3 is rotated in the restriction, also can make stable the fixing on girder 4 of dog 51 simultaneously, accomplishes when girder 4 rotates along with girder 4 is together rotated, ensures under any moment, and dog 51 all supports two and rotates piece 3.

In this embodiment, the stoppers 51 are fixed to the two opposite end surfaces of the main beam 4 after the installation is completed, and the subsequent devices are also used for maintenance and disassembly, so in this embodiment, the stoppers 51 are detachably fixed to the main beam 4, the specific mechanism is the limiting structure 5, and further comprises a U-shaped screw 52 for fixing the two stoppers 51 to the main beam 4, and the two ends of the U-shaped screw 52 penetrate through the two stoppers 51 and are screwed and fixed to the main beam 4 through bolts. After the main beam 4 and the two rotating pieces 3 are stably installed, the two stoppers 51 are connected and fixed with the main beam 4 at corresponding positions. At this time, the two rotating members 3 do not move axially, and the operation of the device is more stable.

In the embodiment, the upright post 1 used for supporting the base 2 is further arranged below the base 2, the upright post 1 is an I-shaped metal pipe, and the I-shaped metal pipe not only provides a plurality of connecting and fixing positions for the connecting support 6, but also facilitates the screwing-in of bolts. Meanwhile, the metal pipe can provide strength required by supporting, and the overall stability and firmness are improved.

In this embodiment, a connection bracket 6 for supporting and fixing the base 2 is further disposed between the column 1 and the base 2, wherein the connection bracket 6 is an inverted U-shaped member, and two ends of the connection bracket 6 are respectively fixedly connected to the column 1. Through the setting of linking bridge 6, base 2 no longer can only be in a height and support girder 4, but the altitude mixture control of accessible linking bridge 6 is fixed to be changed, and the integral erection is more nimble, and adaptability is higher.

The embodiment also provides a photovoltaic power generation device, which comprises the easily-detachable rotating structure. On the basis of ensuring the overall stability and basic azimuth adjustment, part of parts are reduced, so that the overall structure is simpler, and the disassembly, assembly and maintenance are more convenient.
