DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1, as Figures 1 to 3 As shown, the utility model provides an automated inspection device for bridge inspection, including a bridge body 1, a guardrail 2 is fixedly installed on the top of the bridge body 1, a slide groove 3 is opened inside the guardrail 2, a slider 4 is slidably connected inside the slide groove 3, a fixed plate 5 is fixedly installed on the surface of the slider 4, a fixed block 6 is fixedly installed on the bottom of the fixed plate 5, an infrared transmitter 7 is fixedly installed on the left side of the fixed block 6, a detection camera 8 is fixedly installed on the left side of the fixed plate 5, a motor 9 is fixedly installed on the bottom of the fixed plate 5, a connecting shaft 10 is fixedly installed on the output end of the motor 9, a gear 11 is fixedly installed above the connecting shaft 10, a rack 12 is meshed on the surface of the gear 11, a slide groove 2 13 is opened inside the guardrail 2, a slider 2 14 is slidably connected inside the slide groove 13, and a protective shell 15 is fixedly installed on the surface of the slider 2 14.

[0023] The main function of the infrared transmitter 7 is to emit a long-distance laser, which will fall on the inside of the observation rail 17. Therefore, when the fixed plate 5 slides back and forth, the laser emitted by the infrared transmitter 7 will always remain inside the observation rail 17, and whether there is any error in the overall balance of the bridge body 1 can be detected here. The main function of the motor 9 is to drive the gear 11 to rotate through the connecting shaft 10, so that the gear 11 can mesh with the rack 12. The protective shell 15 is fixedly connected to the fixed plate 5, and the interior of the protective shell 15 is hollow. Its main function is to protect the fixed plate 5, the infrared transmitter 7 and the detection camera 8, so as to prevent the infrared transmitter 7 and the detection camera 8 from being affected by rain on rainy days. The practical life of the camera 8.

[0024] Embodiment 2, as Figures 4 to 5As shown, an observation rail 17 is provided inside the guardrail 2, a handrail 16 is fixedly installed above the bridge body 1, and the handrail 16 is located on the left side of the fixed plate 5. A traction steel rope 18 and a fixed column 19 are fixedly installed above the guardrail 2, and a connecting rod 20 is fixedly installed on the surface of the fixed column 19. A drainage outlet 21 is provided at the bottom of the bridge body 1, and the rack 12 is fixedly installed with the guardrail 2, and the rack 12 is located above the fixed plate 5.

[0025] The main function of the railing 16 is to effectively block the fixed plate 5 to prevent the device from being considered damaged due to being placed outdoors for a long time. There are three drain outlets 21, and the three drain outlets 21 are all located on the right side of the railing 16. The main function of the three drain outlets 21 is to promptly drain the accumulated water on the surface of the bridge body 1, thereby preventing excessive accumulation of water on the surface of the bridge body 1 from affecting the detection effect of the device. The main function of the rack 12 is to engage with the gear 11, so that when the motor 9 drives the gear 11 to rotate, it will drive the fixed plate 5 to slide, thereby achieving the effect of moving the fixed plate 5 for detection.

[0026] The working principle and use process of this utility model:

[0027] First, the device is installed. When detection is required, the motor 9 is started to drive the gear 11 to rotate through the connecting shaft 10, so that the gear 11 is meshed with the rack 12, so that the fixed plate 5 can slide left and right, and the infrared transmitter 7 and the detection camera 8 can slide;

[0028] At this time, the infrared transmitter 7 will emit a laser that falls into the inside of the observation rail 17. As the fixing plate 5 slides left and right, the activation emitted by the infrared transmitter 7 will always be inside the observation rail 17. When the laser is offset to the outside of the observation rail 17, the detection camera 8 will observe, thereby achieving the effect of timely reminder;

[0029] At the same time, when it rains, the fixing plate 5, the infrared transmitter 7 and the detection camera 8 are all located inside the protective shell 15, so that they will not be exposed to rain. At the same time, since the bottom of the bridge body 1 is provided with a drainage port 21, water can be discharged in time when it accumulates, so that the internal part of the device will not be damaged by water.

[0030] Finally, due to the automated operation monitoring of the device, manpower and material resources are greatly saved, the efficiency of monitoring is increased, and the accuracy of monitoring is improved.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
