Description

Technical Field

[0001] The utility model relates to the technical field of pipeline monitoring equipment, in particular to a pipeline docking monitoring device for water conservancy construction. Background Art

[0002] In water conservancy construction, the quality of pipeline docking directly affects the safety and long-term operation of the project. Traditional pipeline docking detection usually relies on visual inspection and a small amount of physical detection methods, such as ultrasonic or magnetic particle detection. In recent years, with the development of information technology and sensor technology, pipeline docking monitoring equipment for water conservancy construction has been significantly improved and innovated. The new generation of monitoring equipment uses advanced sensors and data processing technology to monitor various parameters of pipeline docking in real time and accurately, including key indicators such as parallelism, roundness, and sealing of the interface; these monitoring equipment usually use non-contact measurement technology, such as laser ranging and optical imaging visual sensors, to ensure that the docking quality assessment is completed without interfering with the construction process. Through high-precision data collection and analysis, the monitoring equipment can promptly detect and correct potential docking problems, thereby ensuring the reliability and safety of the pipeline during use.

[0003] Existing pipeline monitoring equipment requires operators to push the equipment into the pipeline. When the monitoring equipment reaches the pipeline joint, the equipment begins to monitor the pipeline joint. If the operator pushes the equipment by mistake at this time, it will cause the equipment to shift and need to readjust the monitoring position of the equipment, thereby reducing work efficiency. At the same time, traditional monitoring equipment needs to be at a certain distance from the pipeline joint to monitor the entire pipeline joint, and the working distance of the visual sensor is limited. If the entire pipeline joint is to be monitored, the long distance between the visual sensor and the pipeline joint will increase the monitoring data error. Utility Model Content

The through holes on the inner walls of one end of the four groups of slide grooves on one side of the two groups of cross guide rails 4 are respectively connected with the internal cavities of the two groups of fixed plates 3.

[0025] Among them, one end of the screw rod 7 in the two groups of connecting structures 5 passes through the inner wall through holes at one end of the four groups of slide grooves on one side of the two groups of cross guides 4 and extends to the internal cavities of the two groups of fixed disks 3 respectively.

The screw 7 is rotatably connected to the inner wall of the other end of the four groups of slide grooves on one side of the cross guide 4 at one end. The PLC controller 17 controls the rotation of the power output end of the synchronous servo motor 18 in the internal cavity of the two groups of fixed disks 3. When the power output end of the synchronous servo motor 18 rotates, the screw 7 is driven to rotate.

[0026] Among them, the pushing plates 8 in the two groups of connecting structures 5 are respectively slidably connected to the inside of the cross slide grooves on the outer surfaces of the two ends of the equipment box 1, and the pushing plates 8 in the two groups of connecting structures 5 can slide in the inside of the cross slide grooves on the outer surfaces of the two ends of the equipment box 1 respectively. The bonding plates 9 in the two groups of connecting structures 5 are respectively bonded to the inner walls of the two groups of pipe bodies 2 on the side away from the pushing plates 8, and the pushing plates 8 are moved away from each other. At the same time, the bonding plate 9 at the end of the pushing plate 8 away from the sliding block 6 is pushed to fit the inner walls of the two groups of pipe bodies 2, thereby fixing the equipment box 1 inside the pipe. The pushing plates 8 are moved closer to each other, so that the bonding plate 9 can be separated from the inner wall of the pipe.

[0027] Among them, the lower end of the gear 12 passes through the bottom groove of the annular slide groove in the middle of the equipment box 1 and meshes with the inner side of the inner gear ring 10. When the gear 12 rotates, it can mesh with the inner gear ring 10 to rotate. The outer surface of the inner gear ring 10 is fixedly connected with a visual sensor 19. The visual sensor 19 is electrically connected to the battery 16 and the PLC controller 17 respectively. The battery 16 supplies power to the visual sensor 19. The battery 16 and the visual sensor 19 are electrically connected by an electric slip ring, so that when the visual sensor 19 rotates, it does not hinder the battery 16 from supplying power to the visual sensor 19. The visual sensor 19 is an instrument that uses optical elements and imaging devices to obtain image information of the external environment. After capturing the image, the visual sensor 19 compares it with the reference image stored in the memory to make an analysis. The specific model of the visual sensor 19 can be selected according to the specific usage scenario.

[0028] Among them, the two ends of the transmission rod 13 are respectively rotatably connected to the inside of the through holes on the upper side surfaces of the two groups of ear plates 15, one end of the transmission rod 13 is fixedly connected to the power output end of the driving servo motor 14, and the bottom of the driving servo motor 14 is fixedly connected to the bottom of the equipment box 1, and the driving servo motor 14 is electrically connected to the battery 16 and the PLC controller 17 respectively. The battery 16 supplies power to the driving servo motor 14, and the PLC controller 17 conveniently controls the forward and reverse rotation of the power output end of the driving motor. The PLC controller 17 controls the rotation of the power output end of the driving servo motor 14. The rotation of the power output end of the driving servo motor 14 drives the two ends of the transmission rod 13 to rotate inside the through holes on the upper side surfaces of the two groups of ear plates 15.

[0029] The working principle provided by the utility model is as follows: the operator first pushes and places the equipment box 1 to the docking point of the two groups of pipe bodies 2, and the operator sends a signal to the PLC controller 17. After receiving the signal, the PLC controller 17 controls the power output ends of the synchronous servo motors 18 in the internal cavities of the two groups of fixed disks 3 to rotate respectively. When the power output ends of the synchronous servo motors 18 rotate, the screw 7 is driven to rotate, and when the screw 7 rotates, it is threadedly connected with the threaded hole at one end of the sliding block 6, thereby pushing the sliding block 6 to slide along the four groups of slide grooves on one side of the cross guide rail 4. When the sliding block 6 slides, it pushes the pushing plate 8 to slide inside the cross slide grooves on the outer surfaces of the two ends of the equipment box 1, and the pushing plates 8 move away from each other. At the same time, the pushing plate 8 is pushed away from the fitting plate 9 at one end of the sliding block 6 to fit the inner walls of the two groups of pipe bodies 2, thereby fixing the equipment box 1 inside the pipe and preventing position displacement due to pushing. When the equipment box 1 needs to be taken out, the operator only needs to send a signal to the PLC controller 17. The PLC controller 17 controls the power output end of the synchronous servo motor 18 to reverse, so that the bonding plate 9 can be separated from the inner wall of the pipeline, which is convenient for taking out the equipment box 1. When monitoring the joints of the two groups of pipelines, the operator sends a monitoring signal to the PLC controller 17. After receiving the signal, the PLC controller 17 controls the power output end of the servo motor 14 to rotate. The power output end of the servo motor 14 drives the two ends of the transmission rod 13 to rotate inside the through holes on the upper side surfaces of the two groups of ear plates 15. When the transmission rod 13 rotates, it drives the gear 12 to rotate inside the bottom groove of the annular groove in the middle of the equipment box 1. The gear 12 rotates and engages the internal gear ring 10 to rotate. When the internal gear ring 10 rotates, it drives the visual sensor 19 to look around the joints of the two groups of pipeline bodies 2 for monitoring. The monitoring values ​​collected by the visual sensor 19 are compared with the monitoring standard values ​​set in advance by the PLC controller 17. If the monitoring values ​​are abnormal, the PLC controller 17 will feedback the abnormal monitoring values ​​to the operator.
