Description
Technical Field
The invention relates to a hand-held video acquisition device for detecting a culvert of a highway small bridge, belonging to the technical field of small bridge and culvert detection equipment.
Background
The culvert is a small ground structure arranged when a highway subgrade passes through a depression or crosses a ditch (canal), and the single-hole span of the culvert is less than 5 meters according to the regulations of highway engineering technical standards. The bridge is an overhead artificial channel and consists of an upper structure and a lower structure, and the single-hole span of the small bridge is more than or equal to 5 meters and less than 20 meters according to the regulations of highway engineering technical standards. The application field of the invention mainly aims at the following four types of highway bridges and culverts: 1. small bridges and culverts under construction; 2. small bridges and culverts that have suffered natural disasters (earthquakes, floods, debris flows) or external impacts (vehicle and vessel impacts, etc.); 3. some special small bridges and culverts that need long-term monitoring; 4. the quality of concrete of the upper structure of the highway bridges and culverts in the operating period of the traffic is detected according to relevant regulations of a transportation department; so as to ensure the safe operation of the small bridge and the culvert in the using process of the vehicle. At present, the following methods are generally adopted in the detection of the quality of the upper structure of the small bridge and the culvert: 1. bridge inspection method. The method comprises the steps that a detector detects beam plates, cover beams, rubber supports, support cushion stones, anti-collision check blocks, pull rods and the like of upper structures of a small bridge and a culvert through a detection frame of a small bridge quality detection vehicle; 2. unmanned aerial vehicle method. The method comprises the steps that detection personnel control an unmanned aerial vehicle and detect the structural quality of the upper parts of a small bridge and a culvert by using a camera on the unmanned aerial vehicle; 3. a robotic arm method. The method comprises the steps that a detector controls a mechanical arm, and a camera arranged on the mechanical arm is used for detecting the structural quality of the upper parts of a small bridge and a culvert; 4. climbing method. The method is characterized in that a scaffold or a ladder is erected before detection, and a detector detects beam plates, cover beams, rubber supports, support cushion stones, anti-collision check blocks, pull rods, cover plates and the like of upper structures of small bridges and culverts by climbing the scaffold or the ladder. However, the above method still has the following problems in actual detection work. The bridge inspection method has the problems that: 1. the method is lack of complete video image record, the appearance quality of the concrete in the detection process can only be detected by visual detection of detection personnel, the related video image data is lack, the defects and the omission judgment are easy to occur when the detection personnel are tired, and the integral quality of the appearance of the concrete at the upper part of the detected small bridge cannot be objectively reflected; 2. the detection site has poor adaptability, low working efficiency and is limited by objective conditions; 3. the safety is poor, and the detection personnel are easily damaged by accidents such as lightning stroke, high-altitude falling, mechanical impact, wild bee and ant attack and the like. A plurality of casualty events are detected in China; 4. the energy-saving and emission-reducing effects are poor, and the consumed resources are more; 5. the flexibility of field detection is poor, when the cross slope of the bridge floor is large, the detection cannot be carried out, and when obstacles (such as water channels, river banks, pipelines and the like) exist under the bridge, the detection cannot be carried out. 6. The culvert project can not be detected, and the bridge inspection frame of the bridge inspection vehicle can not enter the culvert due to the fact that the length of the bridge inspection frame is larger than the single span length of the culvert. The unmanned aerial vehicle method has problems: 1. the position of the defect can not be accurately positioned, and the marking function is lacked. In the detection process, no person is interfered by external factors such as air flow, geomagnetic field, obstacles and the like, and the specific positions of the defects on the bridge and the culvert are not easy to be accurately positioned by reexamination personnel and repair personnel due to the lack of the marking function when the defects are found. 2. The operation difficulty is high. Because the propeller of the unmanned aerial vehicle has certain danger when rotating, safety accidents are easily caused when the unmanned aerial vehicle crashes and is out of control, and therefore, the unmanned aerial vehicle needs to be operated by technical personnel who are trained professionally to take off and land in the detection process; 3. a culvert with a small partial clearance cannot be detected. In highway engineering, the internal space of partial culverts is narrow, such as some drainage culverts, and the culverts are mostly arranged in low-lying areas and even cannot be accessed by detection personnel, and no people in the culverts can not be detected because remote control signals are shielded; 4. the later maintenance cost is high, and the popularization and the application in a large range are not convenient. The unmanned aerial vehicle has the advantages that the use times of components such as a motor, a battery, a radio receiver and the like are limited in the use process of the unmanned aerial vehicle, and the unmanned aerial vehicle is easy to cause serious accidents of falling due to the fact that the unmanned aerial vehicle is not used and maintained in place in the later period, so that parts and parts need to be maintained and replaced regularly in the use process of the unmanned aerial vehicle; 5. the flying height and the flying range are limited. According to the relevant national law, the civil unmanned aerial vehicle needs to report to the air management department before flying, the flying height can not exceed 120 meters, and the civil unmanned aerial vehicle can not fly near airports and some military facilities. The mechanical arm method has problems: 1. The defect position can not be accurately positioned, the marking function is lacked, the mechanical arm carries a camera to shoot the defect in the detection process, and the specific position of the defect on the bridge and the culvert is not easy to accurately position by reexamination personnel and repair personnel due to the lack of the marking function when the defect is found. 2. The later maintenance cost is high, the large-scale popularization and application are not convenient, the use times of the parts such as a motor, an oil pressure system and a battery are limited in the use process of the mechanical arm, and the mechanical arm is easy to damage due to the fact that the later use and maintenance are not in place, so that parts need to be regularly maintained, replaced and replaced in the use process of the mechanical arm; 3. the field detection flexibility is poor, the working principle of the mechanical arm is that the mechanical arm moves to drive the camera to shoot and detect the small bridge and the culvert member, but the mechanical arm cannot enter the bridge or the culvert to detect when obstacles (such as a water channel, a river bank, a pipeline and the like) exist under the bridge or in the culvert in the field detection process of a construction site. 4. The energy-saving and emission-reducing effects are poor, and the consumed resources are more. When the mechanical arm is used for detection, the mechanical arm device moves to be pulled by a tractor, and part of lanes can be occupied in the detection process, so that the passage of vehicles on the bridge floor is influenced. The climbing method has problems: 1. the method is lack of complete video image record, the appearance quality of the concrete in the detection process can only be detected by visual detection of detection personnel, the related video image data are lacked, the defects and the missing judgment are easy to occur when the detection personnel are tired, and the integral quality of the appearance of the concrete at the upper part of the detected small bridge or culvert cannot be objectively reflected; 2. the detection site has poor adaptability, low working efficiency and is limited by objective conditions; 3. the security is poor, and the testing personnel easily suffer from high altitude accident injury of falling.

Through the literature search, the same public reports as the patent of the invention are not found.
