Description

Technical Field

[0001] The utility model relates to the technical field of new energy power generation, in particular to a "T"-shaped double-sleeve linkage photovoltaic support tracking system. Background Art

[0002] The photovoltaic support tracking system is usually arranged in a straight line from north to south, and the daily tracking of the photovoltaic components is achieved by rotating the main axis assembly.

[0003] Existing photovoltaic bracket tracking systems, such as announcement number CN219124151U, are named a main shaft assembly for a photovoltaic bracket and a photovoltaic bracket tracking system. The main shaft assembly for the photovoltaic bracket is used to install the structure to be installed. The main shaft assembly includes: multiple main shafts, the main shaft has a first axis, and the multiple main shafts are arranged in sequence along the first axis; a connecting structure is used to connect two adjacent main shafts, and the connecting structure has a portion that is coplanar with the main shaft, so that the structure to be installed can be slidably arranged on the main shaft assembly along the first axis.

[0004] However, the current photovoltaic support tracking system has the following defects:

[0005] First, the chassis of the photovoltaic support is too bulky and its use scenarios are limited. Existing photovoltaic power stations with tracking systems are often equipped with larger and heavier photovoltaic support chassis and corresponding counterweights to ensure that they can meet the safety requirements of the photovoltaic modules themselves and the corresponding wind loads, snow loads and other loads on the photovoltaic power station. Therefore, they can only be used on the ground and cannot be used on ordinary roofs;

[0006] Second, the photovoltaic tracking bracket itself has many transmission devices and concentrated forces, which poses certain mechanical and safety risks. In order to obtain the best radiation inclination angle, the existing solar tracking system often sets up independent inclination transmission devices for "longitudinal" and "latitudinal", which makes its structure complex and makes the "transmission shaft" bear a large torque force, which can easily cause the supporting fixing device to break or loosen due to concentrated force, and even cause damage and safety accidents;

[0007] Third, the manufacturing and maintenance costs of the entire device are high. Due to the first and second disadvantages of the existing technology, the manufacturing and maintenance costs of the device are high, which affects the economic benefits of the photovoltaic power station;

[0008] Fourth, the scope of application is small. The existing photovoltaic tracking system is generally limited to ground photovoltaic power stations, and is difficult to apply to a large number of general rooftop photovoltaic power stations;

[0009] Therefore, we proposed a "T"-shaped double-sleeve linkage photovoltaic bracket tracking system to solve the above-mentioned problems. Utility Model Content

[0010] The purpose of the utility model is to provide a "T"-shaped double-sleeve linkage photovoltaic support tracking system to solve the problems existing in the prior art proposed in the above background technology.

[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a "T"-shaped double-sleeve linkage photovoltaic bracket tracking system, including a triangular bracket chassis;

[0012] Also includes:

[0013] A T-shaped double sleeve mechanism is installed above the front end of the triangular support chassis, a photovoltaic panel positioning frame is installed on the outer wall of the T-shaped double sleeve mechanism, a warp transmission device is installed at the rear end of the T-shaped double sleeve mechanism, an output end of the warp transmission device is hingedly connected to the T-shaped double sleeve mechanism through a first hinge, and a rear end of the warp transmission device is rotatably connected to the triangular support chassis through a single sleeve structure;

[0014] A transmission rod is arranged above the chassis of the tripod support, a transmission arm is installed on the outer wall of the transmission rod, and one end of the transmission arm is rotatably connected to the transmission rod through a rotating shaft, the other end of the transmission arm is hingedly connected to the photovoltaic panel positioning frame through a second hinge, and a latitudinal transmission device is arranged at one end of the transmission rod.

[0015] Preferably, the T-shaped double sleeve mechanism includes a sleeve seat, a first sleeve, a sleeve and a second sleeve, the first sleeve is arranged inside the sleeve seat, and the first sleeve is rotatably connected to the sleeve seat, one end of the sleeve is fixedly connected to the middle position of the first sleeve, a pad is provided on the outer wall of the sleeve, the second sleeve is sleeve-connected to one end of the sleeve, and the outer wall of the second sleeve is fixedly connected to the photovoltaic panel positioning frame.

[0016] Preferably, the output end of the weft transmission device is transmission-connected to one end of a transmission rod via a coupling.

[0017] Preferably, both ends of the transmission rod are connected to the triangular bracket chassis through bearing seats.

[0018] Preferably, the warp transmission device and the weft transmission device are both gear screw electric push rods.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The triangular bracket chassis of the utility model is an integral whole, and the counterweight is uniformly arranged. If necessary, the weight of the component itself can also be included in the counterweight range, thereby reducing the pressure caused by the counterweight setting and the load-bearing of the roof, so that it can be used on the roof of a general bungalow.

[0021] 2. The transmission structure of the utility model is simple. The bracket can be rotated "integratedly" in two orthogonal directions with each other as a fulcrum. It adopts a unique T-shaped double sleeve mechanism, which can realize the free rotation of the bracket angle from the longitude and latitude directions respectively. It can realize the free rotation in the longitude and latitude directions, thereby meeting the basic requirements of the photovoltaic module to track the optimal inclination angle of solar radiation, and avoiding the problem of having to set up transmission devices in two directions respectively, so that the transmission device of the bracket is not easily damaged.

[0022] 3. The bracket adopts a "tetrahedron-like" component fixing method with high safety. It mainly fixes the T-shaped double sleeve mechanism, the longitudinal transmission device and the transmission arm on the three frames of the photovoltaic panel positioning frame to form a relatively stable tetrahedron structure, so that the bracket achieves high stability.

[0023] 4. The utility model can be operated independently as a "unit", or such "units" can be "connected in parallel" and operated in linkage, sharing the transmission device, so as to achieve the purpose of optimal cost and integrated operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A transmission rod 7 is arranged above the triangular bracket chassis 1, and a transmission arm 8 is installed on the outer wall of the transmission rod 7. One end of the transmission arm 8 is rotatably connected to the transmission rod 7 through a rotating shaft 13, and the other end of the transmission arm 8 is hingedly connected to the photovoltaic panel positioning frame 3 through a second hinge 9. A latitudinal transmission device 12 is arranged at one end of the transmission rod 7.

[0033] See also Figure 1 and Figure 3 The T-shaped double sleeve mechanism 2 includes a sleeve seat 201, a first sleeve 202, a sleeve 203 and a second sleeve 205. The first sleeve 202 is arranged inside the sleeve seat 201, and the first sleeve 202 is rotatably connected to the sleeve seat 201. One end of the sleeve 203 is fixedly connected to the middle position of the first sleeve 202. A pad 204 is arranged on the outer wall of the sleeve 203.
