A distributed photovoltaic fixed device

technical field

The invention relates to the technical field of photovoltaic power generation equipment, in particular to a distributed photovoltaic fixing device.

Background technique

Distributed photovoltaic power generation specifically refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive utilization of energy with broad development prospects. It advocates the principles of nearby power generation, nearby grid connection, nearby conversion, and nearby use. It can not only effectively increase the power generation of photovoltaic power plants of the same scale, but also effectively solve the problem of power loss during boosting and long-distance transportation.

Photovoltaic modules generally refer to solar photovoltaic panels (photovoltaic panels for short), which need to be installed on fixed supports to absorb solar radiation. In the prior art, Chinese patent CN202021903098.9 discloses a photovoltaic panel elevation angle adjustment device for distributed roofs. The upper end of the base is rotatably connected to one end of the photovoltaic panel fixing seat through a connecting frame. One end and the other end of the connecting rod are rotatably connected to the piston rod of the electric cylinder. The four sides of the surface of the photovoltaic panel fixing seat are provided with a reflector angle adjustment mechanism, and four reflector plates are connected to the reflector angle adjustment mechanism.

Although the existing technologies can regulate the elevation angle of photovoltaic boards, there are still the following technical defects in the actual use process: the structure of the electric cylinder and multi -link is adopted, and the external power supply is required during use. Because the photovoltaic board is installed outdoors, it will not only be illuminated by strong light, but also suffers from wind and rain. The use environment of electrical components is very bad. At the same time, the corner adjustment mechanism uses the structure of multiple groups of gears. The overall structure is more complicated. It is difficult to repair, which greatly increases the cost of use and low economic benefits.

The present invention is achieved through the following technical solutions: a distributed photovoltaic fixing device, including a base and a vertical frame fixed at one end of the base. Above the base, an inclined frame is arranged on one side of the vertical frame. The top of the inclined frame is rotatably connected to the top of the vertical frame. One end extends to the inside of the drive tube, and the other end of the screw rod is rotatably connected with a slideway mechanism, which is installed on the bottom surface of the inclined frame; a limit sleeve is set on the screw rod, and the limit sleeve is integrally connected with the vertical frame through an oblique rod; a limit block is arranged on the inner wall of the limit sleeve;

During specific use, the staff uses the crank to rotate the drive tube. Since the drive tube is screwed to the screw, and the limit sleeve can also play a limiting role, the screw can only move forward and backward inside the limit sleeve under the cooperation of the limit block and the chute. Therefore, when the drive tube rotates, it can drive the screw to move forward and backward. When the screw rod moves, the slideway mechanism can drive the tilting frame to rotate with the connection point on the top as the fulcrum, so as to bring the photovoltaic panel to rotate, which realizes the adjustment of the elevation angle of the photovoltaic panel. In order to rotate the driving tube better, the staff can inject lubricating grease into the bearing assembly, the limit sleeve and the chute. The overall structure of the device does not use any electrical components, it is a complete mechanical structure, it is very convenient to operate and maintain, has a long service life, low failure rate, effectively reduces the cost of use, improves economic benefits, and is suitable for popularization.

A further improvement of the present invention is that the slideway mechanism includes a slideway block and a slideway groove, the slideway block is rotatably connected to the end of the screw rod, the slideway groove is installed on the bottom surface of the inclined frame, and the slideway block is slidingly clamped inside the slideway groove. The above connection structure is relatively simple, which can reduce the manufacturing cost.

A further improvement of the present invention is that an oil chamber is provided inside the slideway block, and lubricating grease is injected into the oil chamber, and a plurality of oil outlet holes communicating with the oil chamber are provided on the surface of the slideway block. The structure of the oil chamber can have a good lubricating effect and effectively reduce the friction between the slideway block and the slideway groove.

As a further improvement of the present invention, the slideway block is a T-shaped slide block, and the slideway groove is a T-shaped slideway. The T-shaped structure has better stability and can prevent the slide block from slipping out of the slide groove.

A further improvement of the present invention is that a connection unit is provided on the bottom surface of the photovoltaic panel, and is installed on the top surface of the inclined frame through the connection unit, and the photovoltaic panel and the inclined frame form a detachable structure. The above connection structure can facilitate staff to replace photovoltaic panels, and the operation is very convenient.

A further improvement of the present invention is that the connection unit includes a hook and a fixing cylinder, the hook is installed on the bottom surface of the photovoltaic panel, the fixing cylinder is installed on the top surface of the inclined frame, and the hook can be hung inside the fixing cylinder so that the photovoltaic panel and the inclined frame form a detachable structure. The above connection structure is relatively simple, which can reduce the manufacturing cost.

As a further improvement of the present invention, a reinforcing plate is provided between the base and the vertical frame. Reinforcement plates increase the firmness between the base and the vertical frame.

A further improvement of the present invention is that side baffles are provided on both sides of the base, that is, on both sides of the tilting frame, and the side baffles are in sliding contact with the side walls of the tilting frame. The side baffles can limit the position of the tilting frame, that is, the position of the photovoltaic panel, thereby preventing the tilting frame and the photovoltaic panel from shaking to both sides, and increasing the overall stability of the device.

It can be seen from the above technical solutions that the beneficial effects of the present invention are as follows: during specific use, the staff uses the crank to rotate the drive tube, because the drive tube is screwed to the screw rod, and at the same time the spacer sleeve can also play a position-limiting role. Under the cooperation of the spacer block and the chute, the screw rod can only move back and forth inside the spacer sleeve, so when the drive tube rotates, it can drive the screw rod to move forward and backward. When the screw rod moves, the slideway mechanism can drive the tilting frame to rotate with the connection point on the top as the fulcrum, so as to bring the photovoltaic panel to rotate, which realizes the adjustment of the elevation angle of the photovoltaic panel. In order to rotate the driving tube better, the staff can inject lubricating grease into the bearing assembly, the limit sleeve and the chute. The overall structure of the device does not use any electrical components, it is a complete mechanical structure, it is very convenient to operate and maintain, has a long service life, low failure rate, effectively reduces the cost of use, improves economic benefits, and is suitable for popularization.
