Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a photovoltaic power station online safety monitoring device with a wide monitoring range, including a fixing plate 1, evenly distributed fixing rods 2 are fixedly connected to the front surface of the fixing plate 1, a mounting plate 3 is fixedly connected between the front ends of the evenly distributed fixing rods 2, a reciprocating movement assembly 400 for linear reciprocating movement is installed on the back surface of the mounting plate 3, and an adjusting assembly 500 for adjusting the monitoring angle is installed on the front surface of the mounting plate 3. By the combined use of the reciprocating movement assembly 400 and the adjusting assembly 500 on the front surface of the fixing plate 1, the monitoring range can be effectively improved, making the monitoring range of a single monitoring device wider, so as to meet the monitoring requirements of large-space photovoltaic power stations. It can not only automatically control the monitoring direction, but also be adjusted independently by the staff, facilitating the efficient progress of the monitoring work, thereby effectively improving the practicability of the photovoltaic power station online safety monitoring device.

[0026] It should be noted that triangular support blocks are fixedly connected between the opposite sides of the top and bottom fixing rods 2 and the front surface of the fixing plate 1 respectively. The number of the fixing rods 2 is not less than four. Specifically, the number of the fixing rods 2 is six. Through the cooperation between the fixing rods 2 and the corresponding triangular support blocks, the mounting plate 3 can be stably supported.

[0027] In this embodiment, the reciprocating movement assembly 400 is a structure for driving the monitoring device to perform reciprocating linear motion.

[0028] As Figure 1 、 Figure 2 and Figure 3 shown, the reciprocating movement assembly 400 includes a fixing box 401 fixedly connected to the back surface of the mounting plate 3. The front surface of the fixing box 401 is open. The right inner side wall of the fixing box 401 is rotatably connected with a reciprocating lead screw 402 through a bearing. The reciprocating lead screw 402 is a screw rod that can, without changing the rotation direction of the main shaft, connect both ends with an overcurve through two thread grooves with the same pitch and opposite helix directions, so as to enable the slider to perform reciprocating motion. Two positioning rods 403 are fixedly connected between the left and right inner side walls of the fixing box 401. A moving block 404 is threadedly connected to the outside of the reciprocating lead screw 402. A support plate 405 is fixedly connected to the inside of the fixing box 401. A first driving mechanism 406 is fixedly connected to the left side of the support plate 405. The first driving mechanism 406 can be a servo motor.

[0029] It should be noted that the left end of the reciprocating lead screw 402 is rotatably connected to the right side of the support plate 405 through a bearing. A butt joint block fixedly connected to the inner bottom wall of the fixing box 401 is fixedly connected to the bottom of the first driving mechanism 406. The output shaft of the first driving mechanism 406 penetrates the left side of the support plate 405 and is fixedly connected to the left end of the reciprocating lead screw 402, so that the first driving mechanism 406 can stably drive the reciprocating lead screw 402 to rotate normally.

[0030] In addition, the two positioning rods 403 are symmetrically distributed before and after with the reciprocating lead screw 402 as the center. The right ends of the positioning rods 403 penetrate the moving block 404, so that the moving block 404 can be limited by the two positioning rods 403. Thus, under the action of the threaded rotation thrust on the outside of the reciprocating lead screw 402, the moving block 404 can be driven to perform reciprocating linear motion. A moving hole for the moving block 404 to slide is formed in the front surface of the mounting plate 3, so that the moving block 404 can slide inside the moving hole.

[0031] In this embodiment, the adjusting assembly 500 is a structure for adjusting the monitoring angle of the monitoring device.

[0032] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, the adjustment assembly 500 includes an adjustment block 501 fixedly connected to the front of the moving block 404. An adjustment groove 502 is formed at the top of the adjustment block 501. An adjustment rod 503 is inserted between the left and right sides of the adjustment block 501. A connection box 507 is fixedly connected to the left side of the adjustment block 501. A driven wheel 508 is fixedly connected to the left end of the adjustment rod 503. A connection block 509 is fixedly connected to the inner bottom wall of the connection box 507. A second driving mechanism 510 is fixedly installed on the top of the connection block 509. The second driving mechanism 510 can be a servo motor. An output shaft of the second driving mechanism 510 is fixedly connected to a driving wheel 511.

[0033] It should be noted that two connecting plates 504 are fixedly connected to the outer side of the adjustment rod 503. A monitoring camera body 505 is fixedly installed between the opposite sides of the two connecting plates 504. The monitoring camera body 505 can be connected and fixed to the two connecting plates 504 by means of bolts and nuts. The monitoring camera body 505 is located on the top of the adjustment block 501, enabling the monitoring camera body 505 to rotate normally and stably.

[0034] In addition, two limiting plates 506 are fixedly connected to the inner side of the adjustment groove 502. The two limiting plates 506 are respectively located on the front and back of the connecting plate 504. When the connecting plate 504 is in contact with the top of the front limiting plate 506, the position of the monitoring camera body 505 is perpendicular to the ground. When the connecting plate 504 is in contact with the front of the back limiting plate 506, the back of the monitoring camera body 505 does not contact the top of the adjustment block 501. This not only ensures that the monitoring camera body 505 has a large adjustable space but also protects it, preventing it from being collided due to adjustment errors.

[0035] At the same time, the front of the adjustment groove 502 is open, providing a large adjustable space for the monitoring camera body 505. The outer side of the adjustment rod 503 is rotatably connected to the left and right sides of the adjustment groove 502 through two bearings respectively, enabling the adjustment rod 503 to rotate stably. The top of the driving wheel 511 meshes with the bottom of the driven wheel 508. The diameter of the driving wheel 511 is smaller than that of the driven wheel 508, allowing the driving wheel 511 to drive the driven wheel 508 to rotate precisely.

[0036] The working principle of the above embodiment is as follows:

[0037] When controlling the monitoring device to monitor, the first driving mechanism 406 is started to drive the reciprocating lead screw 402 to rotate. Under the positioning action of the two positioning rods 403, the moving block 404 can perform left - right reciprocating motion, so as to drive the monitoring camera body 505 to perform left - right reciprocating movement through the adjusting block 501, playing a role in monitoring the equipment within a large space range. The second driving mechanism 510 is started to drive the driving wheel 511 to rotate, making the driven wheel 508 rotate, so that the adjusting rod 503 rotates and drives the two connecting plates 504 to rotate inside the adjusting groove 502, enabling the monitoring camera body 505 to adjust the angle, thus meeting the monitoring requirements of different angles. At the same time, under the action of the two limiting plates 506, the adjusted angle can be limited to prevent excessive angle deviation.

[0038] Compared with the prior art, this on - line safety monitoring device for photovoltaic power stations with a wide monitoring range can effectively improve the monitoring range through the coordinated use of the reciprocating movement component 400 and the adjusting component 500 on the front of the fixing plate 1, making the monitoring range of a single monitoring device wider, so as to meet the monitoring requirements of large - space photovoltaic power stations. It can not only automatically control the monitoring orientation, but also be adjusted independently by the staff, facilitating the efficient progress of the monitoring work, thus effectively improving the practicality of the on - line safety monitoring device for photovoltaic power stations and solving the problem of the narrow monitoring range of the existing on - line safety monitoring devices for photovoltaic power stations.

[0039] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technologies are not described in detail in the text.

[0040] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
