Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module processing technology, specifically to a photovoltaic module fixing hole position detection device. Background Technology

[0002] Photovoltaic modules are the core component of a photovoltaic power generation system. Their main function is to convert solar energy into electrical energy to power loads. Photovoltaic panels are usually surrounded by aluminum frames with pre-drilled holes. To ensure accurate installation, the drilling positions need to be checked to detect any missing holes or misaligned holes. Therefore, appropriate hole position detection equipment is required.

[0003] A search revealed an existing patent (publication number: CN215296059U) that discloses an automatic detection device for mounting holes in solar module frames. The device includes a housing, processor, display, slide rail, detection mechanism, left support plate, right support plate, knob, screw, and support plate. The detection mechanism uses a motor-driven lead screw to control the movement of a movable tube. This movable tube, via a movable rod, drives the detection head, which moves linearly along the mounting position of the hole. When the protrusion at the bottom of the detection head passes the hole, it falls into the hole and triggers a recording. Based on the movement of the detection head and the recorded hole position, the device actually detects the position of each hole and calculates and displays the distance between each hole. The device offers good detection results, is practical, simple, and highly efficient.

[0004] However, in the above solution, it is inconvenient to inspect the depth and size of the hole. In actual use, the depth and size of the hole will also affect the final installation quality. Therefore, when the error is large, it will also lead to the production of defective products, resulting in inconvenience in subsequent use.

[0005] In view of this, the present invention proposes a photovoltaic module fixing hole position detection device. Utility Model Content

[0006] This invention proposes a photovoltaic module fixing hole position detection device, which solves the problem of inconvenience in detecting the depth and size of holes in related technologies.

[0007] The technical solution of this utility model is as follows: A photovoltaic module fixing hole position detection device includes a fixing frame; a controller fixedly connected to the lower end of the front of the fixing frame; a stepper motor fixedly connected to the upper end of one side of the fixing frame, the output end of the stepper motor extending into the interior of the fixing frame and fixedly connected to a threaded rod via a coupling, the surface of the threaded rod being threadedly connected to a threaded plate; a detection component mounted on one side of the bottom end of the threaded plate, the detection component being used to detect the hole diameter; a fixing rod fixedly connected to the other side of the bottom end of the threaded plate, the bottom end of the fixing rod being fixedly connected to a distance sensor, the distance sensor being used to detect the distance and depth between holes; and a protective component mounted on the surface of the fixing rod, the protective component being used to shield and protect the distance sensor when it is not in use.

[0008] The detection assembly includes: an electric telescopic rod fixedly connected to one side of the bottom end of the threaded plate, with a detection cylinder fixedly connected to the output end of the electric telescopic rod; a fixed groove formed inside the detection cylinder, with a start switch fixedly connected to the inner top wall of the fixed groove; a sliding block movably connected inside the fixed groove, with a sliding rod extending to the outside of the detection cylinder fixedly connected to the bottom end of the sliding block, and a detection block provided at the bottom end of the sliding rod; and a fixed spring wound around the surface of the sliding rod, with both ends of the fixed spring fixedly connected to the inner bottom wall of the fixed groove and the bottom end of the sliding block, respectively.

[0009] Preferably, the sliding block and the interior of the fixing groove form a sliding structure, and the fixing groove and the sliding block are cross-shaped.

[0010] Preferably, the bottom end of the sliding rod is provided with a fixing screw groove, and the top end of the detection block is fixedly connected with a fixing screw block that is threadedly engaged with the inside of the fixing screw groove.

[0011] Preferably, the protective component includes: a limiting groove formed on one side of the surface of the fixed rod, and bolt holes formed at the upper and lower ends of the front side of the fixed rod; a protective cylinder movably connected to the surface of the fixed rod, and a limiting block fixedly connected to the upper end of the inner wall of the protective cylinder; and a fixing bolt movably connected to the upper end of the front side of the protective cylinder, one end of the fixing bolt extending into the interior of the protective cylinder, and the fixing bolt end forming a threaded engagement structure with the interior of the bolt hole.

[0012] Preferably, the protective cylinder is cylindrical in shape, and the height of the protective cylinder is greater than the height of the ranging sensor.

[0013] Preferably, the surface of the fixing bolt nut is provided with anti-slip textures at equal angles, and the anti-slip textures are arc-shaped.

[0014] Preferably, a sliding structure is formed between one side of the limiting block and the interior of the limiting groove, and the limiting groove and the limiting block are convex in shape.

[0015] Preferably, the inner top wall of the fixing frame is provided with a sliding groove, and the top of the threaded plate is fixedly connected to a sliding plate that slides in the groove. The distance from the aluminum frame surface is detected by a distance sensor. When a hole is encountered, the distance sensor detects a change in depth, which is recorded by the controller to obtain the distance. Then, because the stepper motor has a fixed step distance, the detection block can be accurately moved to the top of the hole. The detection cylinder and the detection block are lowered by an electric telescopic rod. When the hole diameter is small, the bottom of the detection block cannot enter the hole. When the hole diameter is appropriate, the top of the detection block cannot enter the hole. When the hole diameter is large, the detection block can fully enter the hole. This will cause the contact time between the sliding block and the start switch to be different. The hole diameter can be judged by the start time of the start switch. After one hole is detected, the distance sensor is moved to the next hole by the stepper motor to obtain the distance between the two holes. This can realize the automatic detection of hole spacing, depth and hole diameter, making the hole detection more comprehensive and improving its practicality.

[0016] In this invention, the fixing bolts are disengaged from the upper and lower bolt holes to achieve the limiting and fixing of the protective cylinder after sliding up and down. When it is necessary to detect the hole position, the protective cylinder slides up and is fixed. Conversely, the protective cylinder slides down to shield and protect the ranging sensor, avoiding damage to the ranging sensor caused by accidental external collisions, reducing unnecessary maintenance costs, and extending the service life of the ranging sensor.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0025] A preferred embodiment of the photovoltaic module fixing hole detection device provided by this utility model is, for example... Figures 1 to 5 As shown: A photovoltaic module mounting hole position detection device includes a mounting frame 8; a controller 2 fixedly connected to the lower front end of the mounting frame 8; a stepper motor 1 fixedly connected to the upper side of one side of the mounting frame 8, the output end of the stepper motor 1 extending into the interior of the mounting frame 8 and fixedly connected to a threaded rod 6 via a coupling, the surface of the threaded rod 6 being threadedly connected to a threaded plate 7; a detection component 3 mounted on one side of the bottom end of the threaded plate 7, the detection component 3 being used to detect the hole diameter; a fixing rod 11 fixedly connected to the other side of the bottom end of the threaded plate 7, the bottom end of the fixing rod 11 being fixedly connected to a distance sensor 4, the distance sensor 4 being used to detect the distance and depth between holes; and a protective component 5 mounted on the surface of the fixing rod 11, the protective component 5 being used to shield and protect the distance sensor 4 when it is not in use.

[0026] The detection component 3 includes: an electric telescopic rod 303 fixedly connected to one side of the bottom end of the threaded plate 7, with a detection cylinder 302 fixedly connected to the output end of the electric telescopic rod 303; a fixing groove 305 opened inside the detection cylinder 302, with a start switch 304 fixedly connected to the inner top wall of the fixing groove 305; a sliding block 310 movably connected inside the fixing groove 305, with a sliding rod 309 extending to the outside of the detection cylinder 302 fixedly connected to the bottom end of the sliding block 310, and a detection block 301 provided at the bottom end of the sliding rod 309; and a fixing spring 306 wound around the surface of the sliding rod 309, with both ends of the fixing spring 306 fixedly connected to the inner bottom wall of the fixing groove 305 and the bottom end of the sliding block 310, respectively.

[0027] In this embodiment, the electric telescopic rod 303 lowers the detection cylinder 302 and the detection block 301. When the aperture is small, the bottom of the detection block 301 cannot enter the aperture, causing the sliding rod 309 and the detection cylinder 302 to slide relative to each other. This causes the sliding block 310 to rise and contact the start switch 304. The controller 2 records this time to determine the time since the electric telescopic rod 303 started working. When the aperture is suitable, the lower end of the detection block 301 will completely enter the aperture, while the top end of the detection block 301 cannot enter the aperture due to its larger diameter. The above operation is repeated, and the controller 2 records this time. When the aperture is large, the detection block 301 will completely enter the aperture until the bottom of the detection block 301 contacts the bottom wall of the aperture. The above operation is repeated, and the controller 2 records this time. The aperture is determined to be suitable by using three time intervals.

[0028] In a further preferred embodiment of the present invention, a sliding structure is formed between the sliding block 310 and the interior of the fixing groove 305, and the shapes of the fixing groove 305 and the sliding block 310 are cross-shaped.

[0029] In this embodiment, the sliding of the cross-shaped sliding block 310 with the inside of the fixing groove 305 is used to improve the smoothness of the sliding of the sliding rod 309 and the detection block 301.

[0030] In a further preferred embodiment of the present invention, a fixing screw groove 308 is provided at the bottom end of the sliding rod 309, and a fixing screw block 307 that is threadedly connected to the top end of the detection block 301 is fixedly connected to the fixing screw groove 308.

[0031] In this embodiment, the screw block 307 and the screw groove 308 are threaded together to facilitate the assembly and disassembly of the detection block 301 and the bottom of the sliding rod 309, so as to select the appropriate detection block 301 according to the appropriate hole size. Example 2

[0032] Based on Embodiment 1, a preferred embodiment of the photovoltaic module fixing hole position detection device provided by this utility model is as follows: Figures 1 to 5 As shown: The protective component 5 includes: a limiting groove 503 formed on one side of the surface of the fixed rod 11, and bolt holes 502 formed at the upper and lower ends of the front of the fixed rod 11; a protective cylinder 501 movably connected to the surface of the fixed rod 11, with a limiting block 506 fixedly connected to the upper end of the inner wall of the protective cylinder 501; and a fixing bolt 505 movably connected to the upper end of the front of the protective cylinder 501, with one end of the fixing bolt 505 extending into the interior of the protective cylinder 501, and a threaded engagement structure formed between one end of the fixing bolt 505 and the interior of the bolt hole 502.

[0033] In this embodiment, when hole position detection is not required, the protective sleeve 501 slides down to shield the ranging sensor 4, and then the fixing bolt 505 is tightened to be screwed into the bolt hole 502 below. Thus, when not in use, the ranging sensor 4 can be shielded by the protective sleeve 501 to avoid damage to the ranging sensor 4 caused by accidental external collisions.

[0034] In a further preferred embodiment of this utility model, the protective cylinder 501 is cylindrical in shape, and the height of the protective cylinder 501 is greater than the height of the ranging sensor 4.

[0035] In this embodiment, the tall protective cylinder 501 is used to facilitate the shielding and protection of the ranging sensor 4.

[0036] In a further preferred embodiment of the present invention, the surface of the fixing bolt 505 nut is provided with anti-slip textures 504 at equal angles, and the shape of the anti-slip textures 504 is arc-shaped.

[0037] In this embodiment, the use of an arc-shaped fixing bolt 505 improves the anti-slip properties between the user's fingers and the fixing bolt 505 nut, making it smoother for the user to rotate the fixing bolt 505.

[0038] In a further preferred embodiment of the present invention, a sliding structure is formed between one side of the limiting block 506 and the interior of the limiting groove 503, and the limiting groove 503 and the limiting block 506 are convex in shape.

[0039] In this embodiment, the sliding between the convex limiting block 506 and the limiting groove 503 is used to improve the stability of the up-and-down sliding of the protective cylinder 501.

[0040] In a further preferred embodiment of the present invention, a groove 10 is provided on the inner top wall of the fixing frame 8, and a sliding plate 9 that slides and engages with the inside of the groove 10 is fixedly connected to the top of the threaded plate 7.

[0041] In this embodiment, the sliding between the slide plate 9 and the inside of the groove 10 is used to prevent the threaded plate 7 from rotating with the rotation of the threaded rod 6 and to improve the smoothness of the back-and-forth movement of the threaded plate 7.

[0042] The working principle of this utility model is as follows: First, select a suitable detection block 301 according to the diameter of the hole to be detected, so that the lower diameter of the detection block 301 is at the point where the appropriate error of the hole diameter is minimized, while the top diameter of the detection block 301 is at the point where the appropriate error of the hole diameter is maximized. Then, use the threaded engagement of the fixing screw block 307 and the fixing screw groove 308 to firmly tighten and fix the suitable detection block 301 to the bottom end of the sliding rod 309.

[0043] Then align the holes on the aluminum frame of the photovoltaic module with the detection block 301 and the distance sensor 4, so that they are on the same horizontal axis. Then loosen the fixing bolt 505 until it is completely disengaged from the lower bolt hole 502. Then slide the protective cylinder 501 upward and use the sliding between the limiting block 506 and the limiting groove 503 to make the protective cylinder 501 slide up to a suitable height. Then tighten the fixing bolt 505 to tighten it into the upper bolt hole 502, so as to achieve the limiting and fixing of the protective cylinder 501 after sliding.

[0044] Next, the distance from the top of the aluminum frame is detected by the distance sensor 4. Then, the stepper motor 1 is started to drive the threaded rod 6 to rotate. Utilizing the threaded engagement between the threaded rod 6 and the threaded plate 7, the threaded plate 7 slides. When it encounters a hole, the distance sensor 4 detects a change in depth, which is recorded by the controller 2 to obtain the distance. Since the stepper motor 1 has a fixed step distance, and the distance between the detection block 301 and the distance sensor 4 is fixed, the stepper motor 1 will allow the detection block 301 to move accurately above the hole. Then, the electric telescopic rod 303 will work to lower the detection cylinder 302 and the detection block 301. When the hole diameter is small, the bottom of the detection block 301 cannot enter the hole, causing the sliding rod 309 and the detection cylinder 302 to slide relative to each other, thus allowing the sliding rod 309 to slide. When the moving block 310 rises to contact the start switch 304, the controller 2 records the time elapsed since the electric telescopic rod 303 began to operate. When the hole diameter is appropriate, the lower end of the detection block 301 will be fully inside the hole, while the top end of the detection block 301, due to its larger diameter, cannot enter the hole. The above operation is repeated, and the controller 2 records the time elapsed since the electric telescopic rod 303 began to operate. When the hole diameter is large, the detection block 301 will be fully inside the hole until the bottom end of the detection block 301 contacts the bottom wall of the hole. The above operation is repeated, and the controller 2 records the time elapsed since the electric telescopic rod 303 began to operate. By using three time intervals, a shorter time indicates a smaller hole diameter, while a longer time indicates a larger hole diameter, and vice versa.

[0045] Then, the electric telescopic rod 303 is activated, causing the detection block 301 to rise above the hole. After that, the stepper motor 1 is activated, causing the distance sensor 4 to move to the next hole position. The distance between the two holes is then determined. The above operation is repeated to detect the depth and diameter of the hole. When hole position detection is not required, the above steps are reversed, causing the protective cylinder 501 to slide down and shield the distance sensor 4. The fixing bolt 505 is then tightened into the bolt hole 502 below. Thus, when not in use, the distance sensor 4 can be shielded by the protective cylinder 501 to prevent damage to the distance sensor 4 from accidental external collisions.

[0046] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
