Description

Technical Field

[0001] The present invention belongs to the technical field of valve monitoring, and in particular relates to a valve oil leakage photographing monitoring feedback device. Background Art

[0002] Oil depot valves are devices used to control the flow of oil in the depot. The quality of the valves has a significant impact on the safety of the entire oil depot. Valve damage will cause oil leakage. The generated flammable mixed gas can easily cause fire or explosion accidents once it encounters open flames or high temperatures. Therefore, monitoring equipment will be installed at important valve positions in the oil depot to determine whether the valves have oil leakage problems.

[0003] The monitoring device takes pictures of the valve at intervals, transmits the images to the image processing device to determine whether the valve is leaking, and then wirelessly transmits the leak image information to the remote monitoring terminal, thereby achieving rapid judgment and feedback on whether the valve is leaking. For example, the patent CN107147881A proposes a valve leakage monitoring system based on image processing technology. It is based on this image processing technology for monitoring. However, in actual monitoring use, there are still the following problems that affect the monitoring quality: 1. There is a large amount of oil mist and pollutants in the oil depot environment. These oil mist and pollutants will adhere to the surface of the camera lens, causing the image to become blurred or unclear, which in turn has a significant impact on the monitoring judgment of whether the valve is leaking. Currently, the monitoring camera lens is cleaned manually at regular intervals, which is not only cumbersome and inconvenient, but also directly affects the oil mist on the camera lens, which can easily damage the camera and cause significant economic losses. 2. When the surveillance camera transmits the collected image to the image processing device for image analysis, the output impedance of the surveillance camera and the input impedance of the image processing device will change due to environmental factors such as temperature and humidity. When there is a mismatch between the output impedance of the signal source and the input impedance of the target device, signal reflection and transmission loss will occur, affecting the signal transmission quality. This will also affect the image transmission quality between the surveillance camera and the image processing device, and thus the valve leakage cannot be discovered in time, which will have very serious consequences.

[0029] The operating principle of the present invention is described as follows: the monitoring camera 10 is installed in a position facing the valve to be monitored, and the reduction motor 43 is started when working. The reduction motor 43 drives the arc-shaped pressing block 45 to rotate in the trigger shell 41 through the intermediate shaft 42 and the extension rod 44. When the arc-shaped pressing block 45 acts on the trigger switch 46, the feedback signal is given to the PLC controller 16. The PLC controller 16 starts the electric slide 31, the electric heating rod 36 and the power pump 38, and first opens the solenoid valve at the Y-type connecting pipe 37 corresponding to the decontamination liquid buffer box 34. The power pump 38 cooperates with the Y-type connecting pipe 37 to draw the decontamination liquid and transport it to the cleaning nozzle 33, so that the decontamination liquid is evenly sprayed on the surface of the lower transparent baffle 24, and the decontamination liquid will be located on the lower transparent baffle. The oil stains on the surface of the baffle 24 are dissolved, and then the solenoid valve at the detergent buffer box 34 corresponding to the Y-shaped connecting pipe 37 is closed, and the solenoid valve at the water supply buffer box 35 is opened. The electric heating rod 36 heats the clean water in the water supply buffer box 35 and the power pump 38 transports the hot water to the cleaning nozzle 33 for spraying, and the surface of the transparent baffle 24 is flushed and cleaned again. After the flushing is completed, the power pump 38 is turned off by the PLC controller 16, and the PLC controller 16 starts the drive motor 613 again. The drive motor 613 drives the protective plate 614 to rotate, so that the protective plate 614 leaves the upper end of the protective shell 612, and then supplies power to the thrust electromagnetic plate 610. The thrust electromagnetic plate 610 is energized to generate magnetism, and cooperates with the thrust permanent magnet plate 611 to make the hollow lift The seat 63 moves up along the guide rod 61, so that the sponge pad 65 contacts the surface of the transparent baffle plate 24, and the electric slide rail 31 drives the entire dewatering and drying mechanism 6 to move back and forth. The scrapers 66 on both sides of the dewatering and drying mechanism 6 quickly scrape off the water accumulated on the transparent baffle plate 24, and the sponge pad 65 further cleans and wipes the transparent baffle plate 24, and then the hot air blower 67 is started. The hot air blower 67 delivers hot air into the hollow lifting seat 63, and dries the surface of the transparent baffle plate 24 through the drying air duct 68, so that the water stains on the surface of the transparent baffle plate 24 are quickly cleaned, and the hot air dries the sponge pad 65 through the dehumidification air duct 69, ensuring the next stable use of the sponge pad 65, and the oil mist concentration sensor 11 and the ring The ambient temperature sensor 12 monitors the oil mist concentration and air temperature in the environment. The greater the oil mist concentration, the more oil stains are accumulated on the transparent shielding plate 24. The lower the air temperature, the more oil mist condenses when it is cold, and the oil vapor therein will gradually liquefy into oil droplets during the cooling process. Compared with oil mist, oil droplets are more difficult to clean because they have a larger volume and higher adhesion. The oil mist concentration sensor 11 and the ambient temperature sensor 12 feedback signals to the PLC controller 16. When the oil mist concentration is greater and the air temperature is lower, the PLC controller 16 drives the power pump 38 to work at a higher power, thereby increasing the amount of decontamination liquid and flushing hot water to meet the cleaning needs of more oil stains and oil droplets and ensure the cleaning quality. After cleaning is completed, the electric slide 31 moves the U-shaped support plate 32 to the rear side.The rotary motor 25 on the lower side is activated to rotate the transparent shielding plate 24 on the lower side by 90 degrees to a vertical state, and then the flip motor 21 is started. The flip motor 21 drives the middle block 22 to rotate, so that the cleaned transparent shielding plate 24 rotates to the front end of the electromagnetic shielding shell 1, and the other transparent shielding plate 24 rotates to the lower side and is rotated to a horizontal state by the rotary motor 25. The PLC controller 16 then starts the monitoring camera 10 to shoot, which can effectively protect the entire monitoring equipment and prevent the problem of oil pollution directly affecting the monitoring equipment and affecting its service life. It can also effectively clean the monitoring line of sight, and can adjust the cleaning force based on the oil mist concentration and the oil droplet formation degree to ensure the cleaning quality, so that the monitoring equipment can be stably monitored and the monitoring quality is improved. The monitoring camera 10 transmits the collected image to the loader 13, and after relative data loading, the collected image is encoded and decoded by the image encoder 14. The decoded image is then processed by the image processor 15 to determine whether there is an oil leakage problem, and the image containing the oil leakage information is sent to the monitoring main server through the wireless signal transmitter 17. The interval time for the entire arc-shaped pressing block 45 to act on the trigger switch 46 is 60s. After the oil mist concentration sensor 11 feeds back a signal to the PLC controller 16, the PLC controller 16 adjusts the power of the reduction motor 43 according to the oil mist concentration. The higher the oil mist concentration, the more dangerous the environment and the greater the possibility of valve leakage. At this time, the working power of the reduction motor 43 is increased, shortening the time for the arc-shaped pressing block 45 to act on the trigger switch 46, and can start the monitoring equipment at intervals to perform image acquisition and recognition, thereby efficiently determining whether the valve has a leakage problem, and can shorten the monitoring interval time based on the oil mist concentration in the environment, thereby improving the timeliness of monitoring; When controlling the surveillance camera 10 to shoot, the PLC controller 16 drives the insulating plate 83 through the micro push rod 82 to drive the U-shaped conductive plate 84 to move downward, so that the U-shaped conductive plate 84 is in electrical contact with the electrical terminal 85, thereby causing the two batteries 81 to act on the output resistor 54 and the variable resistance mechanism 7 and the input resistor 56 respectively, and the force-adding electromagnetic plates 93 in the two feedback shells 91 are respectively connected in series to the power supply circuits of the two batteries 81. When the force-adding electromagnetic plates 93 are energized, they generate magnetic force to cooperate with the force-bearing permanent magnet plate 94, so that the force-bearing plate 92 drives the force-bearing rod 95 to drive the first synchronous The step plate 97 and the second synchronization plate 98 move upward, thereby driving the mounting housing 99 and the conductive block 912 to move up and down. When the impedance of the input resistor 56 is relatively large, the power supply to the force electromagnetic plate 93 in the signal receiving matching housing 52 is relatively small, and the upward movement distance of the second synchronization plate 98 relative to the first synchronization plate 97 is small, so that the second synchronization plate 98 is located below the first synchronization plate 97. At this time, the conductive block 912 contacts the reverse electrical connection block 911, connecting the reverse power supply circuit of the adjustment motor 74 in the variable resistance mechanism 7, and the adjustment motor 74 reverses to cooperate with the adjustment screw 73. The regulating block 75 drives the conductive contact 76 to move in the opposite direction on the variable resistor rod 71, so that the access resistance of the variable resistor rod 71 gradually increases until the conductive block 912 moves between the positive electrical contact block 910 and the reverse electrical contact block 911. When the impedance of the input resistor 56 is relatively small, the second synchronization plate 98 is located on the upper side of the first synchronization plate 97. At this time, the conductive block 912 acts on the positive electrical contact block 910, connecting the positive power supply circuit of the regulating motor 74, so that the access resistance of the variable resistor rod 71 gradually decreases until the conductive block 912 moves between the positive electrical contact block 910 and the reverse electrical contact block 911. The reverse electrical connection block 911 automatically balances the output impedance of the surveillance camera 10 and the input impedance of the loader 13, eliminating the mismatch between the output impedance and the input impedance, allowing the signal to obtain maximum energy transmission during transmission and minimizing signal reflection and loss. This effectively optimizes the matching of signal transmission between the surveillance camera 10 and the loader 13, thereby reducing the problems of signal reflection and data loss, effectively improving signal quality and stability, and avoiding the problem of image transmission quality being affected, resulting in untimely and inaccurate valve leakage judgment.
