Description

Technical Field

[0001] The invention belongs to the technical field of electrical leakage detection, and in particular relates to a HDPE membrane leakage monitoring device for an organic waste landfill. Background Art

[0002] Landfill technology, as the final disposal method for domestic waste, is still the main method for most cities in China to solve the problem of domestic waste disposal. Organic waste landfills are specific places used to treat and dispose of organic waste. Most landfills use HDPE geomembranes as anti-seepage membranes.

[0003] In today's society, environmental protection issues are increasingly attracting people's attention. As one of the main ways to deal with domestic garbage and waste, landfill leakage is directly related to the surrounding environment and human health. Once leakage occurs, it will not only pollute groundwater and surface water, but also affect soil quality and even damage the ecosystem. Therefore, it is particularly important to conduct timely and effective detection of landfill leakage.

[0004] When a long-term online leakage monitoring system is constructed at a landfill, monitoring electrodes for positioning will be installed under the HDPE geomembrane. The monitored electrical signals will be transmitted to the central processing computer through cables for real-time data analysis to obtain the safe operation status of the landfill's anti-seepage geomembrane. The long-term leakage monitoring system consists of a pre-buried part, a data acquisition and control part, a power supply and control part, and a cloud computing part. The flexible monitoring electrodes laid under the HDPE geomembrane form a grid shape. The flexible monitoring electrodes are connected to the data acquisition and control room at the edge of the site by signal cables. The current distortion caused by the damage of the geomembrane liner can be detected, and the leakage location can be obtained by analyzing the collected electrical data.

[0005] The landfill environment is usually harsh, with various chemicals and humidity, which can cause corrosion of electrode materials, affect their performance and service life, and disrupt the real-time monitoring results of the monitoring system. When the electrode is in poor contact with the HDPE geomembrane, the contact resistance will increase, which will also affect the stability of the entire monitoring system. When the monitoring system is running, it will cause large signal fluctuations or abnormal interruptions. The current landfill leakage monitoring system has certain limitations, and its function only focuses on leakage monitoring. However, when faced with problems such as electrode corrosion or poor contact between the electrode and the membrane, which leads to unstable system operation, the existing solutions are relatively scarce and ineffective. In this case, it is often necessary to invest a lot of manpower and material resources to carry out corresponding processing and investigation by digging deep at the location of the electrode. However, this method is not only complicated and costly, but may also cause a certain degree of damage to the structure of the landfill, affecting its normal operation and protection effect.

A forward and reverse motor 78 for driving the rotating screw 77 to rotate is fixedly installed on the outer wall of the sensing shell 71. A synchronous plate 79 is threadedly sleeved on the rod wall of the rotating screw 77. A pressure switch 710 is fixedly installed on one side of the synchronous plate 79 close to the pressing plate 73. A limiting slider is fixedly connected to one side of the synchronous plate 79. A limiting slide groove that matches and slides with the limiting slider is opened on the inner wall of the sensing shell 71.

[0046] The operating principle of the present invention is described as follows: multiple monitoring electrodes 9 are pre-buried at the designed position, and the contact pressure adjustment mechanism 2 is installed by digging a pit to avoid the installation height of the contact pressure adjustment mechanism 2 affecting the installation of the upper HDPE film. The dual-axis motor 23 drives the two adjusting screws 22 to rotate synchronously through the cooperation of the transmission shaft 24 and the bevel gear assembly 25, and then the adjusting seat 26 drives the adjusting plate 31 to quickly adjust the height position of the monitoring electrode 9 through the threaded sleeve effect of the adjusting screw 22 and the adjusting seat 26, so that the contact between the monitoring electrode 9 and the HDPE film is good, ensuring the stable operation of the entire monitoring system;

[0047] The monitoring electrode 9 transmits the monitored electrical signal to the main control computer 1 through the cable 10, and performs real-time data analysis to obtain the safe operation status of the anti-seepage geomembrane of the landfill (this is the prior art and will not be described in detail). When the main control computer 1 detects that the signal of the entire monitoring system has a large fluctuation or the signal is abnormally interrupted, the monitoring electrode 9 at the corresponding position is located, and the main control computer 1 first controls the double-axis motor 23 to reverse, so that the monitoring electrode 9 is relatively retracted into the hollow installation frame 21, so that the monitoring electrode 9 is out of contact with the HDPE membrane, and then supplies power to the monitoring electrode 9 through the cable 10. At this time, the monitoring electrode 9 is connected in series to the power supply circuit of the feedback electromagnetic plate 55. The feedback electromagnetic plate 55 is energized to generate the same magnetism as the feedback permanent magnet plate 54, thereby driving The movable sliding plate 53 moves along the guide slide bar 52 to overcome the elastic force of the reset spring 56. Specifically, when the monitoring electrode 9 is corroded, the resistance of the monitoring electrode 9 will increase, thereby reducing the power supply current of the feedback electromagnetic plate 55, thereby weakening the magnetism of the feedback electromagnetic plate 55, and reducing the sliding distance of the sliding plate 53. At this time, the conductive block 57 is still in contact with the electrical connection bar 58. The conductive block 57 and the electrical connection bar 58 feed back electrical signals to the master control computer 1, indicating that the current monitoring electrode 9 is corroded. The more serious the corrosion of the monitoring electrode 9 is, the greater the resistance of the monitoring electrode 9 is, and the weaker the magnetism of the feedback electromagnetic plate 55 is. Similarly, the sliding distance of the conductive contact 59 on the resistor rod 510 is shorter, and the access resistance of the resistor rod 510 is smaller.

[0048] The conductive contact piece 59 and the resistor rod 510 are connected in series to the power supply circuit of the thrust electromagnetic plate 65. When the thrust electromagnetic plate 65 is energized, it generates the same magnetism as the thrust permanent magnet plate 64, thereby driving the movable plate 63 to slide along the limit slide rod 62 to overcome the elastic force of the return spring 68. When the monitoring electrode 9 is more severely corroded, the access resistance of the resistor rod 510 is smaller. At this time, the magnetism of the thrust electromagnetic plate 65 is stronger, so that the sliding distance of the movable plate 63 is larger, thereby driving the trigger round head 66 to press the number confirmation switch 67 on the rear side, indicating that the monitoring electrode 9 will be wiped and cleaned more times in the future;

[0049] After confirming the rust condition of the monitoring electrode 9, the master control computer 1 controls the electric push rod 43 to push the electric winding roller group 45 out of the outer expansion shell 41, so that the cleaning cloth 46 wound on the electric winding roller group 45 is in contact with the outer side of the monitoring electrode 9. At this time, the cleaning liquid is transported to the contact shell 47 from the outside through the water supply pipe by a pump, and then the cleaning liquid is infiltrated into the cleaning cloth 46 through the seepage hole 48. The electric slide rail 42 drives the electric winding roller group 45 to move, and the outer surface of the monitoring electrode 9 is cleaned by the cleaning cloth 46. Wipe and clean to remove rust. When the electric slide 42 drives the electric winding roller group 45 to move to one end, the master control computer 1 controls the electric winding roller group 45 to move, rotate the next clean cleaning cloth 46 to the wiping position, and prevent the liquid supply pipe 49 from supplying cleaning liquid into the abutment shell 47, drive the electric slide 42 to move in the opposite direction, dry wipe and remove dirt on the outer surface of the monitoring electrode 9, complete a cleaning wiping action, and confirm the number of cleaning wiping actions based on the number of times the corresponding position is triggered. The switch 67 determines the number of cleaning wiping actions;

[0050] After the cleaning and wiping work is completed, the monitoring electrode 9 is powered again through the cable 10, and the current resistance state of the monitoring electrode 9 is confirmed by the rust state detection feedback mechanism 5. If the rust is completely removed, the resistance value of the monitoring electrode 9 becomes smaller and returns to a normal value. At this time, the power supply current of the feedback electromagnetic plate 55 is relatively large, so that the conductive block 57 is no longer in contact with the electrical connection bar 58. The main control computer 1 does not receive the electrical signal fed back by the conductive block 57 and the electrical connection bar 58, indicating that the rust is completely removed. However, if the rust on the outer surface of the monitoring electrode 9 is still relatively serious at this time, the conductive block 57 is still in contact with the electrical connection bar 58, indicating that the rust state of the monitoring electrode 9 can no longer be cleaned and eliminated, and the monitoring electrode 9 needs to be replaced. The main control computer 1 sends a signal to the receiving terminal of the staff to remind the staff to make corresponding processing;

[0051] When the rust of the monitoring electrode 9 is solved after cleaning, the master control computer 1 controls the dual-axis motor 23 to rotate forward again, so that the monitoring electrode 9 contacts the HDPE film again, and observes whether the monitoring signal returns to normal. If the signal returns to normal, it means that the current problem has been solved. If the signal has not returned to normal, it means that the problem has not been solved, and it may be that the monitoring electrode 9 is not in good contact with the HDPE film.

[0052] At this time, the master control computer 1 controls the dual-axis motor 23 to rotate forward, driving the monitoring electrode 9 to move further toward the HDPE film, increasing the contact pressure. After the monitoring electrode 9 reaches the maximum displacement, the signal has not recovered, indicating that the problem has not been solved. The master control computer 1 sends a signal to the receiving terminal of the staff to remind the staff to make corresponding processing;

[0053] When the monitoring system is in normal use, the temperature sensor 8 monitors the ambient temperature in real time. When the ambient temperature is high, the master control computer 1 controls the power supply device to supply a larger current to the force electromagnetic plate 75. The force electromagnetic plate 75 is energized to generate a larger magnetic force equal to that of the force-bearing permanent magnet plate 74, thereby driving the pressing plate 73 to slide a greater distance along the positioning slide bar 72 to overcome the elastic force of the squeezing spring 76, so that the pressing plate 73 is separated from the pressing contact with the pressure switch 710 on the surface of the synchronization plate 79. At this time, the master control computer 1 simultaneously controls the forward and reverse motor 78 and the dual-axis motor 23 to rotate forward, and the forward and reverse motor 78 drives the rotating screw 77 rotates forward, and the synchronous plate 79 drives the pressure switch 710 to move toward the pressing plate 73 by rotating the screw rod 77 and the threaded sleeve of the synchronous plate 79, until the pressure switch 710 contacts the pressing plate 73, and the feedback signal is given to the master control computer 1, and the master control computer 1 controls the forward and reverse motors 78 and the dual-axis motor 23 to stop the action, so as to deal with the problem that when the temperature rises, the HDPE film expands due to heat and produces displacement with the monitoring electrode 9, resulting in poor contact between the HDPE film and the monitoring electrode 9, and ensure that the monitoring electrode 9 is always in a good contact state with the HDPE film, and ensure the operational stability of the monitoring system;

[0054] On the contrary, when the ambient temperature drops, the power supply current of the force electromagnetic plate 75 becomes smaller, so that the pressing plate 73 is pressed and moved toward the pressure switch 710. After the pressure value of the pressure switch 710 increases, the master control computer 1 controls the forward and reverse motors 78 and the dual-axis motor 23 to reverse until the contact pressure between the pressure switch 710 and the pressing plate 73 returns to the initial value. In response to the drop in ambient temperature, which causes the HDPE film to shrink, the contact pressure between the monitoring electrode 9 and the HDPE film is reduced to avoid the problem of excessive contact pressure easily causing damage to the monitoring electrode 9 and the HDPE film.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
