DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: This embodiment is used to solve the problem that large-span photovoltaic brackets that have been welded are difficult to transport to the site due to terrain restrictions in mountainous agricultural areas. The large-span photovoltaic brackets assembled on site are affected by the topography and environment of the mountainous agricultural areas and are only fastened with bolts, which may easily lead to safety hazards in the use strength of the overall large-span photovoltaic brackets. Moreover, personnel move and weld along the assembled large-span photovoltaic bracket beams, which may easily lead to greater safety hazards.

[0034] See also Figure 1 - Fig. 9 As shown, this embodiment is a large-span photovoltaic bracket automatic welding equipment suitable for mountain agricultural photovoltaic complementarity, including a mobile base 1, a control panel 5 is arranged on the top of the outer wall of the mobile base 1, a plurality of groups of limit top cylinders 102 are embedded on the top of the mobile base 1, and a central beam frame 3 is arranged on the top sliding frame of the limit top cylinder 102, a limit bottom cylinder 105 is arranged on the bottom of the mobile base 1, and an anti-slip mechanism 6 is arranged on the bottom of the limit bottom cylinder 105, and the anti-slip mechanism 6 includes an anti-slip slide frame 601, and a linkage guide wheel 606 and a flip bracket 604 are arranged at the bottom of the anti-slip slide frame 601, and an outer arc mechanism 2 is connected to the outer periphery of the mobile base 1; the outer arc mechanism 2 includes an inner arc frame 201 and an arc guide frame 207, and a connecting cylinder arm 204 facing the central beam frame 3 is arranged at the bottom of the inner arc frame 201, and a side kit 303 is arranged on the inner wall of the central beam frame 3, and a detachable welding gun 4 is arranged on the outer wall of the side kit 303;

[0035] The control panel 5 is internally provided with a processor, a data acquisition module, a data analysis module and a signal execution module; the data acquisition module is used to collect the motion detection fluctuation value YDz on the mobile base 1 and the weldment damage value HJz on the central beam frame 3 of the welding device during use, and send the motion detection fluctuation value YDz and the weldment damage value HJz to the data analysis module via the processor; 5 minutes during the use of the welding device is set as the time threshold;

[0036] It should be noted that: the mobile detection fluctuation value YDz is expressed as the average value of the maximum and minimum values ​​of the connection between the beams that meets the welding spacing obtained by the mobile base 1 moving on the beam of the large-span photovoltaic support within the time threshold and detecting that the connection between the beams meets the welding spacing. A certain gap exists after the initial assembly of the beams is restricted by fasteners or external accessories, waiting for subsequent welding reinforcement. The value of the mobile detection fluctuation value YDz reflects whether the beams meet the welding conditions, and the larger the value of the mobile detection fluctuation value YDz, the larger the spacing between the beams, and the lower the connection strength after conventional welding. The weldment defect value HJz is expressed as a parameter of the defect state on the beam in the welding point area obtained within the time threshold. In addition, the mobile detection fluctuation value YDz is collected by a high-definition camera installed at the bottom of the mobile base 1, and the weldment defect value HJz is collected by an infrared scanning sensor installed on the detachable welding gun 4;

[0037] After receiving the mobile detection fluctuation value YDz and the weldment loss value HJz, the data analysis module immediately analyzes the mobile welding loss efficiency of the welding device. The specific analysis process is as follows;

[0038] Obtain the motion detection fluctuation value YDz and weldment damage value HJz within the time threshold, and use the formula The moving welding loss efficiency coefficient R is obtained, where a and b are the proportional coefficients of the moving detection fluctuation value YDz and the weldment damage value HJz, respectively, a>b>0, and R is represented as the moving welding loss efficiency coefficient. The preset moving welding loss efficiency Y stored and entered is retrieved from the processor for comparison and analysis with the moving welding loss efficiency R;

The generated signal is sent to the signal execution module through the processor. After receiving the repair welding reinforcement signal, the signal execution module immediately controls the limit top cylinder 102 to work. At the same time, the processor generates a "weld point abnormality" style text according to the repair welding reinforcement signal, and sends it to the display screen of the remote control device through a communication connection, and at the same time issues an alarm to remind the operator;

After the rotary cylinder four 402 is successfully connected to the connecting cylinder arm 204, the electromagnetic adsorption of the rotary cylinder 307 and the rotary cylinder four 402 is disconnected, and the rotary cylinder three 307 is driven by the regulating cylinder 306 to move away from the rotary cylinder four 402. At the same time, the rotary cylinder three 307 rotates and resets, and waits for the regulating cylinder 306 to drive the rotary cylinder three 307 to telescope close to the top of the central beam frame 3.

The arc-shaped electric guide rail 3 208 is connected to the traction frame 209 through the electromagnetic buckle. The electromagnetic buckle on the arc-shaped electric guide rail 1 205 releases the connection with the traction frame 209, and the arc-shaped electric guide rail 3 208 drives the traction frame 209 Move along the arc guide frame 207 to move in an arc track.

4. According to claim 1, a large-span photovoltaic bracket automatic welding equipment suitable for mountainous agricultural photovoltaic complementarity is characterized in that: The control panel (5) is internally provided with a processor, a data acquisition module, a data analysis module and a signal execution module; The data acquisition module is used to collect the motion detection fluctuation value YDz of the welding device located on the mobile base (1) and the weld defect value HJz located on the central beam frame (3) during use, and send the motion detection fluctuation value YDz and the weld defect value HJz to the data analysis module via the processor. The motion detection fluctuation value YDz is expressed as the average value of the maximum value and the minimum value of the connection between the beam bodies that meet the welding spacing detected by the mobile base (1) moving on the beam body of the large-span photovoltaic support within a time threshold, and a certain gap after the initial assembly of the beam body is restricted by fasteners or external accessories. Waiting for subsequent welding reinforcement, the value of the mobile detection fluctuation value YDz reflects whether the beams meet the welding conditions, and the larger the value of the mobile detection fluctuation value YDz, the larger the spacing between the beams, and the lower the connection strength after conventional welding. The weldment defect value HJz is expressed as a parameter of the defect state on the beam in the weld point area obtained within the time threshold. In addition, the mobile detection fluctuation value YDz is collected by a high-definition camera installed at the bottom of the mobile base (1), and the weldment defect value HJz is collected by an infrared scanning sensor installed on a detachable welding gun (4); After receiving the mobile detection fluctuation value YDz and the weldment defect value HJz, the data analysis module immediately analyzes the mobile welding loss efficiency of the welding device. The specific analysis process is as follows: the mobile detection fluctuation value YDz and the weldment defect value HJz within the time threshold are obtained, the mobile welding loss efficiency coefficient R is obtained through a formula, and the preset mobile welding loss efficiency Y stored and entered is retrieved from the processor for comparison and analysis with the mobile welding loss efficiency R; if the mobile welding loss efficiency R≥the preset mobile welding loss efficiency Y, it is determined that there is an abnormality in the range of the welding points in the area within the time threshold, and a repair welding reinforcement signal is generated. The generated signal is sent to the signal execution module through the processor. After receiving the repair welding reinforcement signal, the signal execution module immediately controls the limit top cylinder (102) to work; if the mobile welding loss efficiency R<the preset mobile welding loss efficiency Y, no signal is generated.
