In the long-term use process, the steel structure will be affected by load, environmental erosion, material fatigue and other factors. In order to ensure that it always meets the design requirements and safety standards and ensures the reliable operation of related projects and equipment, it is necessary to regularly detect the strength of the steel structure

[0014] Preferably, the inner wall of the upper cover is fixedly connected with a third fixed block, the inner wall of the third fixed block is provided with a light supplementing lamp, one end of a wire fixedly connected to the outer wall of the light supplementing lamp is fixedly connected with a battery box, and the inner wall of the battery box is provided with a first conductive sheet.

[0016] Working principle: when in use, the steel structure to be detected is placed on the detection area of the detection table, then the first electric push rod is started to move the fixed plate inward to fix the steel structure, the second electric push rod is started to move the moving frame downward, thereby driving the detection mechanism to move downward to the detection position to detect the steel structure, and the second motor is started to rotate the threaded rod to drive the sliding block to move horizontally, so that the detection mechanism can cover different areas of the steel structure to realize comprehensive detection.

[0017] After the detection camera is moved downward by the moving frame and the slider is moved horizontally left and right by starting the second motor to detect the steel structure, the third electric push rod can be started to move the moving plate upward and slide in the inner wall of the first fixed frame and drive the rotating column one to move upward. In the process of moving upward, the rotating column one drives the first gear to move upward, and the first gear is engaged and connected with the first rack to rotate the first gear and drive the rotating column one to rotate. The rotating column one rotates through the fixed block one to drive the detection camera to flip. At the same time, in the process of flipping the rotating column one, the rotating column one drives the connecting block one to flip, so that the round pin flips, and with the continuous upward movement of the moving plate, the round pin slides into the upper inner wall of the sliding groove one to keep the fixed block one always in a horizontal state. The upward movement of the detection camera makes it slide into the inner wall of the protection cylinder;

[0018] In the process of starting the second electric push rod to move the detection camera downward by the moving frame to detect the steel structure, the downward movement of the moving frame drives the connecting frame to move downward, the connecting frame drives the upper cover to move downward and slide in the outer wall of the sliding rail one, and the fixed block two moves downward to drive the third rack to move downward, thereby rotating the second gear in the inner wall of the second fixed frame. In the process of rotating, the second gear drives the second rack to move upward and drives the lower cover to move upward and slide in the inner wall of the sliding rail two. In this process, the second rack slides in the inner wall of the second sliding groove, and the third rack slides in the third sliding groove to provide guidance for movement and ensure stability. The reverse movement and contact of the upper cover and the lower cover form a closed detection area;

[0019] The downward movement of the connecting frame drives the upper cover to slide downward along the outer wall of the sliding rail one. When the upper cover slides downward, the disc is pulled by the pulling bar one to rotate around the rotating column two. When the disc rotates, the lower cover is pulled by the pulling bar two to slide upward along the outer wall of the sliding rail two, so as to realize the synchronous opposite movement of the upper cover and the lower cover. The reverse movement and contact of the upper cover and the lower cover form a closed detection area;

[0020] In the process of starting the second electric push rod to move the detection camera downward by the moving frame to detect the steel structure, the third electric push rod can be started to flip the fixed block one and drive the dust collection head to flip downward. Then, the exhaust fan is started to operate to generate negative pressure through the exhaust pipe and the dust collection head to perform dust adsorption operation on the detection area forming a closed space, so as to timely remove the dust on the surface of the steel structure and the detection area

[0021] In the process of the moving component driving the upper and lower shields to move toward each other and contact and form a closed space, the lower shield will drive the conductive piece 2 to move upward through the connecting block 2, and at the same time the upper shield will drive the conductive piece 1 to move downward through the battery box. When the upper and lower shields are about to close, the conductive piece 2 contacts the conductive piece 1, thereby prompting the fill light to be powered on. After the two contact, a power circuit is formed for the fill light, and the fill light starts to work. When the upper and lower shields form a closed detection space, the fill light is powered on and emits light synchronously to provide an additional light source for the detection camera.

[0022] The present invention provides an automatic detection device for steel structure strength, which has the following beneficial effects:

[0023] 1. The present invention forms a seal on the detection area by moving the upper and lower shields in opposite directions and making them contact, thereby reducing the interference of external stray light and strong light on the detection camera's built-in light, avoiding light disorder caused by the interaction between external light and the built-in light, and ensuring that the built-in light can clearly illuminate the subtle features of the steel structure, such as cracks and deformation, thereby ensuring that the image captured by the detection camera is clearer and the details are more complete, providing a more reliable visual basis for steel structure strength detection.

[0024] 2. The present invention starts the exhaust fan to generate negative pressure, and then absorbs dust in the detection area forming a confined space through the exhaust pipe and the dust suction head. Dust on the surface of the steel structure and the detection area can be removed in time, and dust is prevented from adhering to the lens of the detection camera or the surface of the steel structure to affect the imaging clarity of the detection camera, thereby ensuring that the detection camera can accurately capture the detailed features of the steel structure.

[0025] 3. In the present invention, when the upper and lower shields form a closed detection space, the fill light is simultaneously powered on to provide an additional light source for the detection camera, effectively compensating for the problem of insufficient light in the detection camera itself, ensuring that in a closed environment or in dim light, the detection camera can still clearly capture the details of the steel structure surface, thereby improving the accuracy and reliability of detection. At the same time, the fill light only works when the upper and lower shields are closed to form a detection space, that is, when fill light is needed for auxiliary detection, and automatically powers off when separated. This can avoid the fill light from consuming power ineffectively in the non-detection state, saving energy, and reducing unnecessary working time of the fill light, reducing equipment loss, extending its service life, and avoiding interference of excess light to operators or the surrounding environment.

[0054] Specifically, in the process of moving the assembly to drive the upper cover 4 and the lower cover 5 to respectively face and contact each other and form a closed space, the lower cover 5 will drive the conductive sheet two 2807 to move upward through the connecting block two 2806, and at the same time, the upper cover 4 will drive the conductive sheet one 2805 to move downward through the battery box 2804, when the upper cover 4 and the lower cover 5 are about to be closed, the conductive sheet two 2807 contacts the conductive sheet one 2805 to make the light supplement lamp 2802 in an energized state, and after the two contacts, the light supplement lamp 2802 forms an energized loop, and the light supplement lamp 2802 starts to work, when the upper cover 4 and the lower cover 5 form a closed detection space, the light supplement lamp 2802 is synchronously energized and emits light to provide an additional light source for the detection camera 22, effectively compensating for the insufficient light problem of the detection camera 22 itself, ensuring that the detection camera 22 can still clearly capture the details of the steel structure surface in a closed environment or in a relatively dark condition, improving the accuracy and reliability of detection, at the same time, the light supplement lamp 2802 only works when the upper cover 4 and the lower cover 5 are closed to form a detection space and need light supplement to assist detection, and automatically cuts off power when separated, which can not only avoid invalid power consumption of the light supplement lamp 2802 in a non-detection state, save energy, but also reduce unnecessary working time of the light supplement lamp 2802, reduce equipment wear and tear, prolong its service life, and avoid interference of excess light on the operator or the surrounding environment.
