To sum up, the present invention has effectively realized the three-dimensional motion of robot in water, the complicated water condition of adaptation that can be fabulous, and can survey distortion, the crack of sluice plate, protection-apron one class formation, gate, gate pier, hull bottom lower apron are detected as steel gate corrosion degree, gate sealing situation and are detected and dam lower apron inspection etc., can improve overhaul efficiency to a great extent, and reduce the work risk.
The specific embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Fig. 1 is the scheme drawing of one embodiment of the invention.Fig. 2 is bionical shrimp detection machine people's an internal circuit functional block diagram under water among Fig. 1.Please also refer to Fig. 1 to Fig. 2.
Bionical shrimp detection machine people under water comprises head 1, chest body portion 2 and afterbody 3.Chest body portion 2 connects head 1 and afterbody 3 respectively, chest body portion 2 has control unit 21, air pump 22, preceding air bag 23 and rear gasbag 24, preceding air bag 23 is arranged on the end of chest body portion 2 near heads 1, rear gasbag 24 is arranged on the other end of chest body portion 2 near afterbody 3, air pump 22 connects above-mentioned preceding air bag 23 and rear gasbag 24, chest body portion 2 also is equipped with left propelling unit 25 and right propelling unit 26 near an end of afterbody 3, and air pump 22, left propelling unit 25 and right propelling unit 26 are electrically connected control unit 21.
Among the present invention, head 1 also comprises manipulator 11, camera 12 and light source 13, and manipulator 11, camera 12 and light source 13 are electrically connected above-mentioned control unit 21 respectively.Manipulator 11 can be removed operations such as mud, cutting-off pasture and water, be the removal obstacle that moves ahead, also can carry out sampling operation, and can obtain the take off data of distress in concrete, dislocation by the opening angle of manipulator, can send data in real time to testing staff, some are needed the accurately place of measurement, device for accurately measuring can be installed, improve and measure precision.Camera 12 is installed in the robot front end, and broad angular field of view is arranged, and makes the machine shrimp obtain extraneous information preferably, keeps away operations such as barrier and underwater photograph technical.Light source 13 provides underwater illumination, and brightness is adjustable according to need, can ensure to obtain preferably scene under water.
Among the present invention, control unit 21 is in embedded microcontroller.
Among the present invention, chest body portion 2 also comprises communication system units 27, is electrically connected above-mentioned control unit 21 and the (not shown) of communicating by letter with ground-surface control computer.
In the present embodiment, the inflation by air bag 23 before 22 pairs of the air pumps and rear gasbag 24 and bleed and realize the come-up and the sinking of robot.For example, air bag 23 inflations before 22 pairs of control unit 21 control air pumps, when rear gasbag 24 is bled, robot come-up.When air bag 23 before 22 pairs of control unit 21 control air pumps bleed, during to rear gasbag 24 inflations, robot then sinks.Can realize the porpoising of robot like this.
In the present embodiment, left propelling unit 25 and right propelling unit 26 can be propeller, utilize left propelling unit 25 and right propelling unit 26 can realize the forward movement and the side-to-side movement of robot.When robot needed turnon left, the rotating speed of the propeller on the left side reduced, and the propeller rotating speed on the right improves; When robot needed right-hand corner, the rotating speed of the propeller on the left side improved, and the propeller rotating speed on the right reduces.The side-to-side movement that rotating speed how to control propelling unit 25 and right propelling unit 26 as for a left side is realized robot belongs to common practise to those skilled in the art, is not described in detail at this.
Be example now to detect sluice plate, to bionical shrimp under water detection machine people each several part function carry out overall introduction: robot sinks down into surveyed area under water by the cooperation of preceding air bag 23 and rear gasbag 24.If the underwater environment complexity, control unit 21 control manipulators 11 are removed operations such as mud, cutting-off pasture and water, are the removal obstacle that moves ahead.When robot ambulation during in the sluice plate face, 12 pairs of cameras under water scene make a video recording and by communication system units 21d real-time Transmission to ground-surface control computer.When the testing staff finds the crack, start measurement mechanism, obtain feeding back on the control computer after the data, judge whether that according to image and data needs handle.To some more tractable structural failure, robot can carry out simple and easy reparation to it by the repairing apparatus of assembling.
Communication between detection machine people and the testing staff can be adopted wireless and wired this dual mode, when being detected, the low head building can adopt wireless mode, when head is higher, can adopt the wire communication mode, to improve the stability that under-water robot is communicated by letter with ground-surface control computer, provide reliable assurance for finishing detection task under water.For safety with prevent unexpected the generation, adopt wire communication mode comparatively safe feasible under the As-Is.The higher embedded microcontroller control of intelligent degree is adopted in the control of detection machine shrimp, and it can control, control flexible, easy to operate by the display and operation platform, controls in real time etc.
To sum up, the present invention has effectively realized the three-dimensional motion of robot in water, the complicated water condition of adaptation that can be fabulous, and can survey distortion, the crack of sluice plate, protection-apron one class formation, gate, gate pier, hull bottom lower apron are detected as steel gate corrosion degree, gate sealing situation and are detected and dam lower apron inspection etc., can improve overhaul efficiency to a great extent, and reduced the work risk, and the complicated water condition of adaptation that robot energy of the present invention is fabulous, and can when being absorbed in mud, escape danger voluntarily.
Concrete case study on implementation only is a preferable case study on implementation of the present invention described in the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be as technology category of the present invention.
