Description

Technical Field

[0001] The present invention relates to the technical field of sensor nodes, and more particularly to a self-organizing network underground pipeline leakage monitoring sensor node device. Background Art

[0002] Self-organizing network underground pipeline leakage monitoring is a system that uses wireless sensor network technology to achieve real-time monitoring and early warning of underground pipeline leakage. The basic functional units of the wireless sensor network of sensor node devices use their own micro-embedded sensing, processing, communication and power units to complete the underground pipeline leakage monitoring task through self-organizing network collaboration. In summary, the inventors have discovered that existing sensor node devices have the following major drawbacks: Since the current sensor node devices are connected to the surface of the embedding location only through a locking frame and locking bolts during embedding installation, multiple locking bolts on the edge of the locking frame must be locked one by one after embedding. During locking, the different locking forces of each locking bolt gradually cause the monitoring point of the device to tilt and shift, making it difficult to align the monitoring point of the device with the pipeline, thereby reducing the accuracy of the monitoring position; At the same time, because the sensor node device is positioned by embedded locking, after the device is embedded in the underground area, the embedded position of the device body will be affected by the pressure changes of the underground environment, which can easily affect the operating stability of its own components due to pressure changes. Summary of the Invention

The carbon steel frame of the pressure protector is combined with the metal plate at the edge of the frame and the protruding rod and the adsorption frame. The adsorption frame adsorbs and positions the middle and lower layers of the locking frame. At the same time, the carbon steel frame is combined with the sliding frame of the welding layer to carry the anti-rust shell and the sensor body and embed them in the connection part of the underground pipeline. Then, the side blocks and clamps of the slot in the limit frame of the frame are used to fix and cover the outside of the anti-rust shell.

[0009] As a further improvement of the present invention, the protruding rod is in the form of a small round rod embedded in the inner side of the adsorption frame and has a metal plate on the connection surface with the frame body. The limiting frame covers the edge of the slot to allow the side blocks and the clamping parts to be installed in parallel and form a symmetrical distribution.

[0010] As a further improvement of the present invention, the clamping member is provided with a flexible clamping block, the upper end of the flexible clamping block is fused to the lower end of the elastic block and the upper end of the elastic block is connected to a balance plate to vertically position the plug block, and a reinforcement pad is provided above the plug block for the bolt to pass through.

[0011] As a further improvement of the present invention, the flexible clamping block is connected to the upper and lower parts of the slot through an elastic block, the balance plate at the upper end of the elastic block is parallel to the inner wall position of the limit frame and the insert block is embedded in the limit frame, and the reinforcement pads are arranged outside the frame and are parallel to each other so that the bolts pass through to lock the center of the insert block.

[0012] As a further improvement of the present invention, the flexible clamping block is also provided with a center block, which is fixed at the lower end of the rubber block and a connecting block is provided at the upper end of the rubber block. The top of the connecting block also includes a fusion auxiliary block embedded in the bottom center of the elastic block.

[0013] As a further improvement of the present invention, the central block is a solid rectangular shape and the connecting block at the upper end of the rubber block is trapezoidal in shape. The upper end of the connecting block is covered by the fusion auxiliary block and is interlaced and fused with the lower end of the elastic block.

[0014] As a further improvement of the present invention, the sensing node is provided with an insulating frame, and the insulating frame has an insulating plate built in to install the positioning block at the edge of the inner wall of the insulating frame and to position the sound sensing module, humidity sensing module, and pressure sensing module. A picture monitor is also provided on the left and right sides of the insulating frame and the insulating plate and in the distance between the sound sensing module, humidity sensing module, and pressure sensing module.

[0015] As a further improvement of the present invention, the insulating frame and insulating plate are both made of plastic and the positioning block is in a concave shape. The sound sensor module, humidity sensor module and pressure sensor module are spaced apart by the positioning block so that the image monitor can be installed in parallel.

[0016] As a further improvement of the present invention, the image monitor is further provided with a power block, which passes through the center of the flat panel and enters the left and right sides of the horizontal plate to be electrically connected to the internal light camera. A vertical partition is also mounted in the center of the horizontal plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on the rust-proof shell and the pressure-resistant protector provided on the outside of the sensor body. The cooperation of the rust-proof shell can improve the protection of the surface of the sensor body. The provided locking frame can be reinforced according to the adsorption frame of the pressure-resistant protector, thereby preventing the position deviation of the sensor node caused by the different forces when the locking bolts are locked one by one. Subsequently, the carbon steel frame can be linearly embedded in the connection position of the underground pipeline through the sliding frame of the protrusion and the edge welding layer, ensuring the parallel embedding stability of the sensor body. At the same time, the double-layer covering protection of the carbon steel frame and the rust-proof shell can avoid the damage to the overall stability of the sensor body due to the change of underground pressure after embedding, thereby improving the stability and accuracy of the sensor body's monitoring of the underground pipeline.

[0019] 2. The present invention is a further improvement of the clamping piece on the inner wall of the limit frame of the carbon steel frame. The balance plate is set outside the frame body to allow the bolts to pass vertically through and connect with the internal plug-in block, thereby ensuring the verticality of the elastic block and the flexible clamping block at the bottom of the balance plate. In addition, the flexible clamping block can contact the surface of the rust-proof shell through the rubber block and the center block. After the center block is embedded, the rubber block will be in parallel contact with it, thereby improving the coverage and protection strength of the embedded position of the sensor body and avoiding the position deviation caused by the lack of a center point during assembly.

[0020] 3. After further improvement of the sensor node, the present invention can improve the position assembly accuracy of the sound sensor module, humidity sensor module, and pressure sensor module of the positioning block through the cooperation of the insulating frame and the insulating plate, and at the same time avoid power leakage during power-on operation. Subsequently, the image monitor equipped in the interval can allow the light camera to be stably installed according to the cooperation of the horizontal plate. When the sound sensor module, humidity sensor module, and pressure sensor module are operating, the light camera also operates through the power-on block to provide image monitoring of the monitoring status of the underground pipeline. If a leak occurs, the image of the leaking area can be transmitted, further improving the accuracy of locating the leaking area. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings: Example

[0034] Among them, the sensor node 1 is arranged at the front end of the sensor body 2 and the sensor body 2 has an independent power supply, a constant temperature cooler, and a wireless signal transmitter built in.

[0035] The area of ​​the adsorption frame 51 is consistent with that of the carbon steel frame 52 , and the top protrusion 53 of the carbon steel frame 52 is solid and is welded to the sliding frame 55 through the welding layer 54 on the edge.

The limiting frame 523 covers the edge of the slot 524 to allow the side block 525 and the clamping piece 526 to be installed in parallel and form a symmetrical distribution.

[0038] Among them, the flexible clamping block 5261 is connected to the upper and lower parts of the slot 524 through the elastic block 5262, the balance plate 5263 at the upper end of the elastic block 5262 is parallel to the inner wall position of the limit frame 523 and the insert block 5264 is embedded in the limit frame 523, and the reinforcement pad 5265 is arranged outside the frame body 522 and is parallel to each other so that the bolt 5266 passes through to lock the center of the insert block 5264.

[0040] The center block 2611 is a solid rectangular shape and the connecting block 2613 at the upper end of the rubber block 2612 is trapezoidal in shape. The upper end of the connecting block 2613 is covered by the fusion auxiliary block 2614 and is interlaced and fused with the lower end of the elastic block 5262.

[0041] Specific functions and operation procedures of this embodiment: In the present invention, the sensor body 2 of the self-organizing network underground pipeline leakage monitoring sensor node device can be embedded in the connection position of the underground pipeline through the locking frame 4 of the rust-proof shell 3 and the pressure protector 5. After embedding, it can be locked in parallel through the locking frame 4, allowing the sensor node 1 to monitor the pipeline in real time. If a leak occurs, the data monitored by the sensor node 1 will be transmitted to the central processing platform via wireless mode to promptly notify relevant personnel to conduct investigation and processing to complete the monitoring operation of the underground pipeline. When embedded in the connection position of the underground pipeline, the rust-proof shell 3 it carries can avoid external damage to the sensor body 2 caused by the influence of underground humidity. At the same time, the carbon steel frame 52 of the pressure protector 5 can lock the connection position of the locking frame 4 through the adsorption frame 51. Adsorption reinforcement is carried out to ensure that the locking bolt on the edge of the locking frame 4 is affected by the locking force of different forces, which affects the monitoring position accuracy of the sensor node 1, thereby improving the stability and accuracy of locking. At the same time, the carbon steel frame 52 can be linearly embedded in the connection position of the underground pipeline through the top protrusion 53 and the sliding frame 55 of the edge welding layer 54, achieving linear embedding, and then allowing the locking frame 4 to be stably locked in position. At the same time, the protruding rod 521 on the surface edge of the frame body 522 of the carbon steel frame 52 can be embedded in the inner side of the adsorption frame 51, and the connection position of the two is equipped with a metal plate to allow the adsorption frame 51 to be parallel adsorbed, ensuring that the adsorption frame 51 can stably adsorb and restrain the lower position of the locking frame 4 to maintain the effect of parallel locking, and then the limit frame 523 of the frame body 522 can The side block 545 and the clamping piece 526 are installed in combination with the slot 524. For this reason, the rust-proof shell 3 is inserted into the frame 522 through the slot 524 and is spliced ​​with the side frame 525 and the clamping piece 526, and finally embedded in the connection position of the underground pipeline. For this reason, the carbon steel frame 52 and the rust-proof shell 3 can be used for auxiliary embedding to achieve protection of the outside of the sensor body 2, avoid damage to the sensor body 2 caused by pressure changes at the connection position of the underground pipeline, and improve the effect of the safe embedding connection of the entire sensor body 2. Then, the balance plate 5263 of the clamping piece 526 can be embedded in the limit frame 523 through the top plug 5264, and then the external reinforcement pad 5265 can be used to allow the bolt 5266 to penetrate vertically and lock. The elastic block 5262 and the flexible clamping block 5261 at the lower end of the balance plate 5263 can maintain a parallel state. Finally, after the flexible clamping block 5261 contacts the surface of the rust-proof shell 3, it can squeeze the elastic block 5262. At the same time, the rust-proof shell 3 can be clamped and fixed according to the rebound effect, and the pressure change in the underground pipeline area can be alleviated through the cooperation of the elastic block 5262, further improving the protection strength of the sensor body 2. Finally, the rubber block 2612 of the flexible clamping block 5261 can be integrated with the bottom of the elastic block 5262 through the fusion auxiliary block 2614 of the top connecting block 2613, so that the two will be an integrated structure. Then the rubber block 2612 can be combined with the center block 2611 to complete the interlaced and restrained contact with the outside of the rust-proof shell 3.This improves the surface clamping stability of the entire device. The rubber block 2612 prevents scratching, and the center block 2611 prevents looseness and instability caused by incorrect assembly due to a lack of surface restraint. The coordination of these components effectively improves the stability of the overall sensor node device in real-time monitoring of underground pipelines. Example

[0046] Specific functions and operation procedures of this embodiment: In the present invention, the insulating frame 11 of the sensor node 1 can be used with the insulating plate 12 to position the positioning block 13 and the sound sensor module 14, the humidity sensor module 15, and the pressure sensor module 16, so that the insulating material can prevent the power leakage generated when the sound sensor module 14, the humidity sensor module 15, and the pressure sensor module 16 are powered on, thereby improving the safety factor effect during real-time monitoring. Then, the image monitor 17 carried in the gap can be embedded in the side position of the sound sensor module 14, the humidity sensor module 15, and the pressure sensor module 16 through the power block 171 of the flat plate 172, achieving the light camera 175 of the horizontal plate 173. The power connection is turned on so that the light camera 175 can provide image monitoring of the underground pipeline location. When a leak occurs, the sound sensor module 14, the humidity sensor module 15, and the pressure sensor module 16 transmit the relevant data, and the light camera 175 also transmits the leak location captured, thereby achieving the effect of quickly locating the leak area, saving the subsequent one-by-one inspection process, and improving the efficiency of repairing the underground pipeline. The horizontal plate 163 can separate the two groups of light cameras 175 through the vertical partition 174 in the center, so that they have a safe distance to improve the accuracy of the shooting image and avoid the occurrence of overlapping.
