[0042] First of all, it should be noted that in the following description, some directional words, such as "front", "back", "upper", "lower", etc., are involved in order to clearly explain the technical solution of the present invention. Figure 1The flame sensor detector 12 and the laser combustible gas detector 13 extend out of the direction of one end of the support beam riser 601, or the direction of travel of the intelligent inspection robot when the drive motor 201 rotates forward, "backward" refers to the direction opposite to "forward"; "upward" refers to the direction opposite to "forward"; Figure 1 In the direction close to the ground, "up" refers to the opposite direction of "down". The terms are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "setting", "connection" and "installation" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figure 1 As shown, the intelligent inspection robot provided by the present invention includes a robot chassis 1, a driving component 2 arranged on the robot chassis 1, a rotating connection component 3 connected to the driving component 2, and a bridge plate 4 connected to the rotating connection component 3, wherein the driving component 2 includes a driving motor 201, a driving shaft 202 connected to the driving motor 201, and a conveyor belt 203 rotating around the driving shaft 202; the rotating connection component 3 includes a connecting rod 301, a sliding sleeve 302 connected to the connecting rod 301, and a sliding rod 303 slidably connected to the sliding sleeve 302; an annular slide groove 401 is formed on the bridge plate 4, and the connecting rod 301 is slidably connected in the annular slide groove 401; the sliding rod 303 is fixedly connected to the conveyor belt 203, so that when the driving motor 201 drives the conveyor belt 203 to rotate, the bridge plate 4 can be flipped from the top to the bottom of the robot chassis 1, and can drive the bridge plate 4 to flip from the bottom to the top of the robot chassis 1 after the robot chassis 1 passes over the bridge plate 4.

[0045] The intelligent inspection robot of the present invention is provided with a robot chassis 1, on which a driving component 2 is provided, on which a rotating connection component 3 is provided, and on which a bridge plate 4 is connected, wherein the driving component 2 includes a driving motor 201, a driving shaft 202 and a conveyor belt 203, and the driving motor 201 is fixedly connected to the robot chassis 1. Preferably, the robot chassis 1 is provided with a receiving cavity for installing the driving motor 201, which can be used to fix the driving motor 201 and can also be used to not interfere with the driving motor 201 when the bridge plate 4 is located above or below the robot chassis 1. In addition, the driving shaft 202 is connected to the driving motor 201, and the conveyor belt 203 is wrapped around the outer circumference of the driving shaft 202. When the driving shaft 202 rotates, it can also drive the conveyor belt 203 to rotate synchronously, thereby driving the rotating connection component 3 to move. Figure 1 It can be seen that the drive shaft 202 is set at both ends of the robot chassis 1 in the length direction, and the conveyor belt 203 can be wrapped around the drive shaft 202 at both ends along the length direction of the robot chassis 1, so that the bridge plate 4 can be turned 360° around the robot chassis 1. When the drive motor 201 is set to rotate forward or reverse, the bridge plate 4 can be turned upward or downward from both ends of the length direction of the robot chassis 1, so that the intelligent inspection robot of the present invention can achieve obstacle climbing in the process of moving forward or backward, and there is no need to turn the intelligent inspection robot around to climb over obstacles, and the use effect is better. It can be seen that the length and width of the bridge plate 4 are determined according to the width of the obstacle ditch that needs to be climbed at the use site and the spacing between the wheels 5 of the intelligent inspection robot. When the width of the obstacle ditch is wider, the length of the bridge plate 4 needs to be increased. In order to support the weight of the bridge plate 4, the power of the drive motor 201 and the structural strength of the rotating connection component 3 need to be increased accordingly to meet the use requirements.

[0046] Furthermore, the rotating connection component 3 includes a connecting rod 301, a sliding sleeve 302 and a sliding rod 303. The sliding sleeve 302 is slidably connected to the sliding rod 303, so that the distance between the end face of the sliding rod 303 and the central axis of the connecting rod 301 can be adjusted, thereby achieving the use requirement of the distance change of the connection part between the bridge plate 4 and the robot chassis 1 during the flipping process of the bridge plate 4 through the rotating connection component 3.

[0047] Furthermore, the annular groove 401 of the present invention is arranged in the middle area of ​​the bridge plate 4, and the annular groove 401 includes two symmetrically arranged arc portions and two parallel straight groove portions. Each arc portion is arranged at both ends of the width direction of the bridge plate 4, and the two straight groove portions are respectively located on the upper surface and the lower surface of the bridge plate 4, and the two arc portions are connected to the two straight groove portions.

[0048] As a preferred embodiment of the present invention, the number of the drive shafts 202 is two, which are respectively arranged at the two ends of the length direction of the robot chassis 1, and the drive motor 201 is connected to one of the drive shafts 202. The two drive shafts 202 are respectively arranged at the two ends of the robot chassis 1, and a recessed structure can be set at the two ends of the robot chassis 1, or a mounting bracket can be set at the two ends of the robot chassis 1, both of which can realize the installation of the drive shaft 202, and both belong to the protection scope of the present invention. In addition, the drive motor 201 of the present invention and the drive shaft 202 can also be connected by belt transmission or gear meshing transmission.

[0049] As another preferred embodiment of the present invention, Figure 2 As shown, a sleeve cavity 3021 is formed at the end of the sleeve 302 away from the connecting rod 301, a sleeve limiting edge 3022 is provided on or integrally formed at the edge of the sleeve cavity 3021, and a slide rod limiting flange 3031 is provided on or integrally formed at the end of the slide rod 303 close to the connecting rod 301, and the slide rod limiting flange 3031 is suitable for abutting against the sleeve limiting edge 3022 to limit the slide rod 303 from slipping out of the sleeve cavity 3021.

[0050] Further preferably, a spring 304 is further provided in the sleeve cavity 3021 , one end of the spring 304 is connected to the slide rod 303 , and the other end of the spring 304 is connected to the bottom of the sleeve cavity 3021 .

[0051] In the present invention, the spring 304 is preferably a tension spring, and the end of the slide rod 303 and the bottom of the sleeve cavity 3021 are both provided with a mounting structure, or the two ends of the spring 304 are directly fixedly connected with the slide rod 303 and the bottom of the sleeve cavity 3021 (such as welding connection or adhesive connection). In addition, if the sleeve cavity 3021 is formed as a cavity structure with two ends open, the bottom of the sleeve cavity 3021 can be understood as the outer peripheral surface of the connecting rod 301. When the connecting rod 301 is connected to the sleeve 302, the outer peripheral surface of the connecting rod 301 is formed as the bottom surface of the sleeve cavity 3021. At this time, one end of the spring 304 is connected to the slide rod 303, and the other end is connected to the outer peripheral surface of the connecting rod 301. The spring 304 can make the slide rod 303 quickly reset after being stretched, drive the bridge plate 4 to quickly separate from the ground, and shake off the soil on the bridge plate 4. It is conceivable that a protruding structure may be provided on the robot chassis 1 to scrape off dirt and other debris on the bridge plate 4 .

[0052] Preferably, the sleeve cavity 3021 of the present invention is formed as a cavity structure with a square or rectangular cross-section. Correspondingly, the cross-section of the slide rod 303 is a columnar structure with a square or rectangular shape, which can effectively limit the circumferential rotation of the slide rod 303 when it is slidably connected in the sleeve cavity 3021. There is no need to set up an axial limiting structure separately. The structure is simple and the use effect is good.

[0054] In the present invention, Figure 4 As shown, two annular grooves 401 are provided, and the two annular grooves 401 are symmetrically arranged, and the connecting rod sliding shafts 3012 at both ends of the connecting rod 301 are slidably connected in the annular grooves 401, which can provide a guiding effect for the rotating connecting component 3, and also play a certain limiting effect. At the same time, it can be imagined that the connecting rod sliding shaft 3012 can be directly slidably connected in the annular groove 401, or a copper sleeve structure can be set on the connecting rod sliding shaft 3012, which can improve the wear resistance of the connecting rod sliding shaft 3012, or a bearing is set on the connecting rod sliding shaft 3012, and the bearing is controlled to move in the axial direction through the shaft elastic retaining ring, and the outer ring of the bearing is connected to the annular groove 401, which can not only improve the installation accuracy of the connecting rod sliding shaft 3012 and the annular groove 401, but also reduce the friction between the connecting rod sliding shaft 3012 and the annular groove 401, thereby effectively improving the service life of the connecting rod sliding shaft 3012.

[0055] As a specific structural form of the present invention, Figure 3 As shown, the two ends of the bridge plate 4 in the width direction are formed with parallel bridge plate inclined surfaces 402, and the bridge plate inclined surfaces 402 are formed as inclined surfaces inclined upward. This structure enables the bridge plate 4 to be used on the other side after one side is worn, thereby improving the use efficiency.

[0056] As another specific structural form of the present invention, a plurality of wheels 5 are further provided on the robot frame 1. When the bridge plate 4 is flipped to the bottom of the robot frame 1, each wheel 5 can roll along the upper surface of the bridge plate 4, and at the same time, the connecting rod 301 slides along the annular groove 401.

[0057] Specifically, the intelligent inspection robot of the present invention is provided with four wheels 5, and six, eight or more wheels 5 may be provided according to actual use requirements, all of which fall within the protection scope of the present invention.

[0058] As another specific structural form of the present invention, support beams 6 are provided on both sides of the length direction of the robot chassis 1, and a gas detector 7, a camera 8, a valve opening identifier 9, a sound collector 10, an infrared thermal imager 11, a flame sensor detector 12 and a laser combustible gas detector 13 are provided on the support beams 6.

[0059] In the present invention, the gas detector 7 can detect the concentration of hydrogen, hydrogen sulfide, oxygen or other combustible gases. The camera 8 is a high-definition camera with high-definition, fog-penetrating, low-illumination clear imaging functions. It can clearly image at night under low brightness conditions and can meet the needs of uninterrupted monitoring day and night. The sound collector 10 can identify and collect on-site sounds. The infrared thermal imager 11 can display the position of the highest temperature point and the temperature value in the image, and has thermal map data. It can detect abnormal heat sources based on thermal imaging technology and promptly discover leakage of equipment and pipelines. The flame sensor detector 12 can quickly identify the source of fire. The laser combustible gas detector 13 can perform real-time detection of the concentration of combustible gases in the environment and alarm for abnormal conditions.

[0060] More specifically, the support beam 6 includes a support beam vertical plate 601 and a support beam horizontal plate 602, wherein the gas detector 7 is arranged on one of the support beam vertical plates 601, the flame sensor detector 12 and the laser combustible gas detector 13 are arranged on the other support beam vertical plate 601, the camera 8 and the valve opening identifier 9 are arranged on one of the support beam horizontal plates 602, and the sound collector 10 and the infrared thermal imager 11 are arranged on the other support beam horizontal plate 602. In the present invention, the number of the support beam vertical plates 601 and the support beam horizontal plates 602 are both two, which are respectively arranged on both sides of the length direction of the robot chassis 1 and connected by welding or fasteners.

[0061] Typically, the intelligent inspection robot of the present invention also includes a control system, which is electrically connected to the drive component 2, the gas detector 7, the camera 8, the valve opening identifier 9, the sound collector 10, the infrared thermal imager 11, the flame sensor detector 12 and the laser combustible gas detector 13.

[0062] In addition, a monitoring device is also installed on the support beam 6 of the present invention, and the monitoring device includes a monitoring unit, a power supply unit and a processing unit, wherein the monitoring unit is used for patrol monitoring, and the power supply unit includes a battery, and the power supply unit provides power for the patrol robot. The data information obtained by the gas detector 7, the camera 8, the valve opening identifier 9, the sound collector 10, the infrared thermal imager 11, the flame sensor detector 12 and the laser combustible gas detector 13 can be provided to the monitoring unit, and the monitoring unit processes the above information and sends it to the control system.

[0063] like Figures 5 to 8 As shown, the working process of the intelligent inspection robot of the present invention is:

[0064] First, if Figure 5 As shown, the initial position of the bridge plate 4 is set above the robot chassis 1 and parallel to the robot chassis 1.

[0065] Secondly, if Figure 6 As shown, when encountering an obstacle ditch, the driving motor 201 in the driving component 2 drives the conveyor belt 203 to rotate, driving the bridge plate 4 connected to the conveyor belt 203 through the rotating connecting component 3 to rotate. According to the position of the obstacle ditch, the control system controls the driving motor 201 to rotate forward or flip, so that the bridge plate 4 flips forward or backward and is placed above the obstacle ditch. At this time, the bridge plate 4 is located below the robot chassis 1.

[0066] Again, if Figure 7 As shown, the wheel 5 passes over the bridge plate 4. When the intelligent inspection robot moves forward or backward, the connecting rod sliding shaft 3012 slides in the annular groove 401, and the rotating connecting component 3 moves with the movement of the intelligent inspection robot.

[0067] Finally, if Figure 8 As shown, after the intelligent inspection robot passes over the bridge plate 4, the driving component 2 flips the bridge plate 4 from bottom to top, and gradually flips the bridge plate 4 located below the robot chassis 1 to above the robot chassis 1, and returns to the initial position. The intelligent inspection robot completes crossing the obstacle ditch during the inspection process.
