[0037] Example

[0038] Please refer to Figure 1 This embodiment provides a leachate leakage monitoring system 1000 for a domestic waste landfill. The leachate leakage monitoring system 1000 includes: a monitoring matrix component 100 and a data processing mechanism 200.

[0039] The monitoring matrix assembly 100 includes monitoring sensors 110, which are arranged in the soil layer around the domestic waste landfill and around the domestic waste landfill, and the monitoring sensors 110 are distributed in an array. The monitoring sensors 110 are all connected to the data processing mechanism 200 for transmitting monitoring signals to the data processing mechanism 200.

[0040] During use, the monitoring matrix assembly 100 is pre-buried in the soil layer of the landfill pit 500 of the domestic waste landfill site, so that the monitoring sensors 110 of the monitoring matrix assembly 100 are distributed around the landfill pit 500. After the landfill is completed, if the leachate leaks, the leachate will enter the soil layer around the landfill pit 500, and the monitoring sensors 110 at the corresponding positions can detect the leachate. Once the monitoring sensor 110 detects the presence of leachate, it means that the leachate leaks at the position corresponding to the monitoring sensor 110. According to the monitoring signal and the corresponding sensor number information sent by the monitoring sensor 110 to the data processing mechanism 200, the corresponding sensor position can be directly located, thereby determining the leakage position of the leachate.

[0041] Through the above design, the leakage site can be directly and quickly located without turning over the landfill pit 500, and the response sensitivity is very high.

[0042] In general, the leachate leakage monitoring system 1000 for domestic waste landfills has a simple structure and is easy to implement and apply. It can quickly detect the seepage area without turning over the landfill pit 500, and at the same time quickly locate the specific position of the leakage area, which is of positive significance for the monitoring of leachate.

[0043] It should be noted that the monitoring sensor 110 may be a sensor for measuring specific components in the leachate, and by detecting changes in the content of the corresponding substance in the surrounding soil layer, it can reflect whether the leachate has leaked. The type of monitoring sensor 110 can be flexibly selected according to actual conditions, as long as it can indirectly or directly reflect whether the leachate has leaked.

[0044] In this embodiment, the leachate leakage monitoring system 1000 further includes: a remote transmitting station 300 and a central data center 400. The data processing mechanism 200 is connected in communication with the remote transmitting station 300 so that the monitoring data processed by the data processing mechanism 200 can be transmitted to the outside through the remote transmitting station 300. The remote transmitting station 300 is connected in communication with the central data center 400 to transmit the monitoring data to the central data center 400 for remote monitoring.

[0045] Through the above design, the data processing mechanism 200 and the remote transmitting station 300 can be set up in the domestic waste landfill, and the central data center 400 can be set up in a unified office area or a unified management area, so as to realize the unified collection and aggregation of data of various domestic waste landfills. On the one hand, the monitoring information of the central data center 400 can be used to comprehensively reflect and monitor the information of all landfills in real time, so as to optimize the management of various landfills. On the other hand, when a leachate leak occurs in a landfill, the central data center 400 can reflect the leakage situation as a whole and collect relevant data, so as to further optimize the daily maintenance and management of the landfill, and at the same time facilitate the rapid handling of the leakage problem.

[0046] The introduction of the Central Data Center 400 has realized remote unified and transparent management, facilitating the effective improvement of the management quality of the landfill.

[0047] Furthermore, the remote transmission station 300 and the central data center 400 may be connected via 5G signal communication.

[0048] Furthermore, please combine Figures 2-3 The monitoring matrix assembly 100 further includes an auxiliary tube 120. The wall of the auxiliary tube 120 is provided with an opening for exposing the monitoring part of the monitoring sensor 110, and the periphery of the opening is also provided with a ring sleeve 121 for wrapping the side wall of the monitoring sensor 110. The monitoring sensor 110 is installed at the opening and wrapped by the ring sleeve 121, so that only the monitoring part of the monitoring sensor 110 is exposed, reducing the wear of the monitoring sensor 110. In addition, the monitoring part of the monitoring sensor 110 is slightly lower than the height of the ring sleeve 121 to avoid damage to the monitoring sensor 110 when lateral displacement occurs in the soil layer. The data line of the monitoring sensor 110 is connected to the data processing mechanism 200 through the tube cavity 122 of the auxiliary tube 120.

[0049] By providing the auxiliary pipe 120, the monitoring sensor 110 and the data transmission line of the sensor can be effectively protected, and the monitoring sensor 110 can be more easily positioned and installed, thereby reducing the position deviation of the monitoring sensor 110 in the soil layer, thereby making the subsequent determination of the leakage position more accurate. In addition, using the auxiliary pipe 120 as a basic support and basis also makes the arrangement of the monitoring sensor 110 more efficient and convenient.

[0050] In this embodiment, please combine Figures 4 to 6 The monitoring matrix assembly 100 further includes: a connecting member 130, the connecting member 130 includes a first clamping arm 131 and a second clamping arm 132, and the first clamping arm 131 and the second clamping arm 132 are arranged in parallel.

[0051] A first clamping groove 131a for clamping the auxiliary tube 120 is provided on one side of the first clamping arm 131 close to the second clamping arm 132, and first clamping grooves 131a are provided at both ends of the first clamping arm 131. A second clamping groove 132a for clamping the auxiliary tube 120 is provided on one side of the second clamping arm 132 close to the first clamping arm 131. Second clamping grooves 132a are provided at both ends of the second clamping arm 132.

[0052] The first clamping arm 131 and the second clamping arm 132 are detachably attached to each other, so that the first clamping groove 131 a and the second clamping groove 132 a form an enclosed cavity for clamping and fixing the auxiliary tube 120 .

[0053] Specifically, the first clamp arm 131 has an inner cavity, and the inner cavity is rotatably mounted with a first gear 131b, a second gear 131c, a bevel gear and a nut 131e. The second gear 131c is coaxially connected with the bevel gear, the first gear 131b is meshed with the second gear 131c, the nut 131e has a bevel gear ring, and the bevel gear is meshed with the bevel gear ring. The rotation axes of the first gear 131b and the second gear 131c are arranged in parallel, and the rotation axes of the second gear 131c and the nut 131e are arranged vertically. The rotation axis of the first gear 131b passes through the side wall of the first clamp arm 131, and the end surface of the rotation axis is provided with a matching portion 131f for matching with a screwdriver.

[0054] The second clamping arm 132 is fixedly connected with a screw rod 132 b, and the screw rod 132 b cooperates with the nut 131 e, so that when the rotating shaft is rotated, the first clamping arm 131 and the second clamping arm 132 can be driven to approach each other or separate from each other.

[0055] During use, the mating portion 131f is rotated with a screwdriver to drive the first gear 131b to rotate, thereby driving the second gear 131c and the bevel gear to rotate, causing the bevel gear driving nut 131e to rotate. As the nut 131e rotates, the screw rod 132b is driven to move into the nut 131e of the first clamp arm 131 or withdraw from the nut 131e of the first clamp arm 131, thereby making the first clamp arm 131 and the second clamp arm 132 move closer to each other, or driving the first clamp arm 131 and the second clamp arm 132 to separate from each other.

[0056] Specifically, during the arrangement process, the auxiliary tubes 120 with the monitoring sensors 110 installed are arranged first, and then the adjacent auxiliary tubes 120 are connected in pairs using the connector 130. During the connection process, the matching portion 131f is first rotated to separate the first clamping arm 131 and the second clamping arm 132, and then the auxiliary tube 120 is placed between the first clamping groove 131a and the second clamping groove 132a, and then the matching portion 131f is rotated to bring the first clamping arm 131 and the second clamping arm 132 closer to each other, and the auxiliary tube 120 is tightened using the first clamping groove 131a and the second clamping groove 132a, so as to realize the longitudinal arrangement of the auxiliary tube 120.

[0057] Through the above design, the entire monitoring matrix assembly 100 is connected in an integrated manner, which greatly improves the integrity and stability of the monitoring matrix assembly 100 and can avoid displacement in the soil layer. In addition, according to the requirements of the arrangement density of the monitoring sensors 110, the length of the connector 130 can be flexibly selected.

[0058] Furthermore, in this embodiment, the second gear 131c, the bevel gear and the nut 131e are each in two groups and are disposed on both sides of the first gear 131b. The screw rod 132b is also in two groups, and the screw rod 132b is matched with the nut 131e respectively. The first gear 131b, the second gear 131c, the bevel gear and the nut 131e are all located between the two groups of the first clamping grooves 131a.

[0059] A guide piece 131g is provided on the side wall of the first clamp arm 131 close to the second clamp arm 132. Two groups of guide pieces 131g are provided in parallel and on both sides of the first clamp arm 131. The guide pieces 131g are provided perpendicular to the side wall of the first clamp arm 131 close to the second clamp arm 132. The second clamp arm 132 is fitted between the two groups of guide pieces 131g. The side walls on both sides of the second clamp arm 132 are fitted with the guide pieces 131g. The second clamp arm 132 is movably fitted with the guide pieces 131g.

[0060] The guide wire sheet is provided with a sliding groove (not shown in the figure) extending perpendicularly from a side wall of the first clamping arm 131 and close to the second clamping arm 132 , and the second clamping arm 132 is slidably engaged with the sliding groove.

[0061] By providing the guide piece 131 g , the movement stability of the first clamping arm 131 and the second clamping arm 132 during the relative movement is greatly improved, and the tightness of the fit between the first clamping arm 131 and the second clamping arm 132 is improved.

[0062] It should be noted that the data processing unit 200 and the remote transmitting station 300 can be powered by solar energy to adapt to monitoring work in special terrains such as mountainous areas, thereby facilitating energy supply and use.

[0063] This embodiment also provides a monitoring method using the above-mentioned leachate leakage monitoring system 1000 for a domestic waste landfill, which includes: when the monitoring sensor 110 detects a leachate-related signal, determining the specific position of the monitoring sensor 110 that detects the leachate-related signal, that is, the leachate leakage position.

[0064] In summary, the leachate leakage monitoring system 1000 for domestic waste landfills has a simple structure, is easy to implement and apply, can quickly detect the seepage area without turning over the landfill pit 500, and can quickly locate the specific location of the leakage area, which has positive significance for leachate monitoring.
