The moving chassis drives the open section, wheels, brushes of the partition plate, brushes of the cleaning cylinder, and the horizontal end of the shovel plate of the housing to move along the inner wall of the culvert. Under the elastic energy storage of the torsion spring, the shovel plate removes debris from the inner wall of the culvert, and the cleaning cylinder sweeps away debris. The brushes of the partition plate isolate dust from the culvert, preventing dust from entering the housing. The light emitted by the bulb unit passes through the convex... After the lens disperses the light, it shines onto the reflector. Under the action of the reflector, an illumination zone is formed in the open part of the box section. The camera picks up images of the inner wall of the culvert located in the open part of the box section. The back-end computer detects internal defects of the culvert based on the picked-up images. By adjusting the screw, the tilt angle of the reflector is adjusted to adjust the position of the illumination zone in the open part of the box section. After the inspection of the inner wall of the culvert is completed, the motor is put into a non-working state and the bulb is put into a short-power state.

[0053] The technical effect of the above solution is that it enables continuous detection of the inner wall of the culvert and realizes online detection of the inner wall of the culvert.

[0054] In this technical solution, the housing, camera, light source, and reflector are basic components and essential technical features of the invention. The bracket, clamping plate, electrode plate, connecting screw, connecting nut, adjusting screw, follower wheel, isolation plate, cleaning cylinder, motor, shovel, and torsion spring are functional components that enable other technical effects of the invention.

[0099] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0100] A method for using a culvert inner wall inspection device based on rainwater and sewage diversion includes the following steps: rotating the connecting nut 8 on the connecting screw 7, separating the connecting nut 8 from the connecting screw 7, separating the upper plate 51 from the connecting screw 7, placing the light source 4 on the lower plate 52, placing the flange 47 on the lower end face of the dark box 41 into the receiving groove 53 on the lower plate 52, and contacting the lower terminal 45 with the second plate 62, thereby arranging and installing multiple light sources 4 in a manner. On the lower plate 52, the through hole of the upper plate 51 is connected to the connecting screw 7, so that the flange 47 on the upper end face of the dark box 41 is placed into the receiving groove 53 on the upper plate 51, so that the upper terminal 44 contacts the first plate 61, and the connecting nut 8 rotates in the opposite direction on the connecting screw 7. The upper connecting nut 8 acts on the upper plate 51, thereby installing the light source 4 between the upper plate 51 and the lower plate 52, and between the first plate 61 and the second plate 62.

[0101] When inspecting the inner wall of the culvert, the open portion of the box section 11, the wheel section 911, the brush body of the partition plate 92, the brush body of the cleaning cylinder 93, and the horizontal end of the shovel plate 95 are placed on the inner wall of the culvert. The bracket 2 is connected to the moving chassis through the mounting holes, the motor 94 is in working condition, and the bulb section 42 is energized. The moving chassis drives the open portion of the box section 11, the wheel section 911, the brush body of the partition plate 92, the brush body of the cleaning cylinder 93, and the horizontal end of the shovel plate 95 to move on the inner wall of the culvert. Under the elastic energy storage of the torsion spring 96, the shovel plate 95 removes debris from the inner wall of the culvert, and the cleaning cylinder 93 sweeps away debris from the inner wall of the culvert. The brush body of the isolation plate 92 isolates dust in the culvert, preventing dust from entering the box section 11. The light emitted by the bulb section 42 is dispersed by the convex lens section 43 and then shines on the reflector 9. Under the action of the reflector 9, an illumination zone is formed in the open part of the box section 11. The camera 3 captures images of the inner wall of the culvert located in the open part of the box section 11. The background computer detects internal defects of the culvert based on the captured images. The tilt angle of the reflector 9 is adjusted by adjusting the screw 90 to adjust the position of the illumination zone in the open part of the box section 11. After the detection of the inner wall of the culvert is completed, the motor 94 is put into a non-working state and the bulb section 42 is put into a short-power state.

[0102] In verifying this invention, the inventors abandoned the existing technical features of directly illuminating the inner wall of the culvert with lighting fixtures to capture images under direct light. Instead, they first proposed a technical feature of creating illumination in the culvert opening area on the inner wall of the culvert. This resulted in the first unexpected technical effect: local illumination of the image capture area was achieved, improving the image capture effect. The second unexpected technical effect: using the housing 1 as a carrier ensured the usability and installation performance of the camera 3, reflector 9, and light source 4. The third unexpected technical effect: the light source 4 could be arranged and combined for installation, allowing for adjustment of the light intensity.

[0103] In the second embodiment of the present invention, the box shell 1, camera 3, reflector 9 and light source 4 are interconnected in a manner that forms lighting for the tunnel opening on the inner wall of the culvert.

[0104] In this embodiment, the reflector 9 and the light source 4 are connected to the housing 1 and the camera 3 in a manner that disperses and reflects the illumination light.

[0105] In this embodiment, a first accessory device is also included and is disposed between the light source 4 and the housing 1. The first accessory device is configured to include a clamping plate 5, an electrode plate 6, a connecting screw 7, and a connecting nut 8.

[0106] In this embodiment, a second accessory device is also included and is disposed between the reflector 9 and the housing 1. The second accessory device is configured as an adjusting screw 90.

[0107] In this embodiment, a third accessory device is also included and is disposed on the housing 1. The third accessory device is configured as a bracket 2.

[0108] In this embodiment, a fourth accessory device is also included and is disposed on the housing 1. The fourth accessory device is configured as a follower wheel 91.

[0109] In this embodiment, a fifth accessory device is also included and disposed on the housing 1. The fifth accessory device is configured as an isolation plate 92.

[0110] In this embodiment, a sixth accessory device is also included and disposed on the housing 1. The sixth accessory device is configured to include a cleaning cylinder 93, a motor 94, a shovel 95, and a torsion spring 96.

[0111] The second embodiment of the present invention is based on the first embodiment.

[0112] In the second embodiment of the present invention, the steps are as follows: the housing 1 provides support for the camera 3, the reflector 9 and the light source 4 inside the opening; the camera 3 acquires image signals from the inner wall of the culvert; and the reflector 9 and the light source 4 disperse and reflect the illumination light, thereby creating illumination of the opening area on the inner wall of the culvert.

[0113] The second embodiment of the present invention is based on the first embodiment.

[0114] This invention has the following characteristics:

[0115] 1. By designing a housing 1, camera 3, reflector 9, and light source 4, the housing 1 provides support for the camera 3, reflector 9, and light source 4 inside the culvert opening. The camera 3 captures image signals from the inner wall of the culvert. The reflector 9 and light source 4 disperse and reflect the illumination light, thus creating illumination for the culvert opening area on the inner wall of the culvert. This solves the technical problem of directly illuminating the inner wall of the culvert with lighting fixtures and capturing images under direct light, thereby improving the imaging effect on the inner wall of the culvert.

[0116] 2. By designing clamping plate 5, electrode plate 6, connecting screw 7 and connecting nut 8, the component connection of light source 4 is realized.

[0117] 3. The position of the reflector 9 is adjusted by the design of the adjusting screw 90.

[0118] 4. Due to the design of bracket 2, it is possible to connect with the motion chassis.

[0119] 5. Due to the design of the follower wheel 91, the movement support of the housing 1 is realized.

[0120] 6. Due to the design of the isolation plate 92, the shell 1 can be kept clean.

[0121] 7. Due to the design of the cleaning cylinder 93, motor 94, shovel 95 and torsion spring 96, the cleaning treatment of the inner wall of the culvert is realized.

[0122] 8. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or by a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0123] 9. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0124] Other technical features that connect to the housing 1, camera 3, reflector 9, and light source 4 that form the lighting for the tunnel entrance on the inner wall of the culvert are also embodiments of the present invention. Furthermore, the technical features of the embodiments described above can be combined in any way. In order to meet the requirements of the Patent Law, the Implementing Regulations of the Patent Law, and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

[0125] The above embodiments are merely one implementation of the culvert inner wall detection device and usage method based on rainwater and sewage diversion provided by the present invention. Other modifications to the solution provided by the present invention, additions or reductions of components or steps, or application of the present invention to other technical fields similar to the present invention, all fall within the protection scope of the present invention.
