The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] like Figures 1 to 9As shown, the present invention is a leakage prevention device for a gas generator set, comprising: a mobile module 1, the mobile module 1 comprises a vehicle body and moving wheels for driving the vehicle body to move; the vehicle body is used to carry a manipulator 2, a fixed module 3, and a detection module 4 arranged thereon; the mobile module 1 is used to move around a gas turbine generator 471 group, so that the detection module 4 can perform leakage prevention detection on the gas turbine generator 471 group; the manipulator 2 is used to move the leakage prevention component 5 from a predetermined position to the mobile module 1 when a gas leakage is detected.

[0034] When the device is detecting, the detection module 4 is driven by the mobile module 1 to patrol along the gas generator 471 group. During the patrol, the gas leakage is continuously detected by the detection module 4. When a gas leak is detected, the detection module 4 sends an alarm message to remind the maintenance personnel to arrive at the leakage site for timely maintenance; at the same time, the mobile module 1 moves to the location where the anti-leakage component 5 is stored. After moving to the destination, the anti-leakage component 5 is moved to the mobile module 1 by the manipulator 2; then the mobile module 1 returns to the leakage site where the gas leak is detected, so that the staff can use the anti-leakage component 5 to deal with the leakage site; if the personnel have arrived at the gas leakage site, the leakage point can be pre-treated with tape. The alarm information includes: leakage situation, target location. The present application adopts an automated patrol method, which reduces the need for manual inspections, increases the frequency and coverage of detection, and the system can achieve 24-hour continuous monitoring, is not affected by human factors, and improves the reliability of monitoring.

[0035] The above patrol includes the following steps:

[0036] S1. Field measure the area around the gas generator 471 group to determine the boundary of the patrol area; based on the measurement results, establish a virtual grid map of the gas generator 471 group in the system and store it in the database; the virtual grid map contains a number of grids, each grid represents a node, and the size of the grid is determined according to the actual layout of the gas generator 471 group, such as 0.5 meters by 0.5 meters; at each node, a pause can be made to detect the node;

[0037] S2, assigning identifiers to each grid node, marking the status of each identifier, such as reachable, unreachable, obstacle, etc.; planning the moving path of the mobile module 1 based on the identifier;

[0038] S3. Use lidar or camera to collect obstacle information. After detecting a dynamic obstacle, use the improved potential field model and hidden Markov model to make intelligent decisions and controls based on the position, speed and other information of the obstacle, and plan an obstacle avoidance path to bypass the obstacle.

[0039] In this embodiment, a detection unit is used for detection, and the detection unit includes: a PLC processor, a gas leakage sensor and an environmental monitoring sensor electrically connected to the PLC processor; the gas leakage sensor is used to continuously monitor the gas concentration in the surrounding environment, and once it detects that the gas concentration exceeds a preset safety threshold, it immediately sends a signal to the PLC processor; the environmental monitoring sensor is used to collect environmental parameters such as temperature, humidity, etc. in real time, and send the data to the PLC processor; the PLC processor receives data from the gas leakage sensor and the environmental monitoring sensor, and processes it according to preset logic and algorithms; for example, for the data of the gas leakage sensor, the PLC processor will determine whether the gas concentration exceeds the safety threshold. If the PLC processor receives a signal exceeding the threshold from the gas leakage sensor, it will trigger the alarm system, issue an audible and visual alarm, and may send an alarm message to the control center or maintenance personnel through the wireless network. At the same time as the alarm, the PLC processor will command the manipulator 2 to move to the position where the anti-leakage component 5 is stored, grab the corresponding anti-leakage component 5, and move it to the mobile module 1; for the data of the environmental detection sensor, the PLC processor will evaluate whether the environmental conditions are suitable for leakage processing.

[0040] The anti-leakage component 5 includes: an arc plate 54, which is used for supporting and limiting, and is composed of two semicircular arc plates 54; one end of the two arc plates 54 is hinged to each other through a hinge block 57, and the other end is provided with a connecting block 56, and the two connecting blocks 56 can be connected together by bolts and nuts to achieve the connection of the two arc plates 54; the inside of the arc plate 54 is sequentially installed with an air storage bag 53, a storage capsule 52, and a sealing sheet 51 from the outside to the center of the circle; the inside of the storage capsule 52 stores sealant; the sealing sheet 5 1 is attached to the inner surface of the storage capsule 52 and is used to seal the storage capsule 52; a plurality of glue outlets are provided on the side of the storage capsule 52 facing the sealing sheet 51, and the colloid in the storage capsule 52 can flow out from the glue outlets; an air inlet pipe 55 is also installed on the side wall of the arc plate 54, and the air inlet pipe 55 is connected to the air storage bag 53 and is used to inflate the air storage bag 53 through the air inlet pipe 55; a mounting block 58 is also installed on one side of the arc plate 54, and the mounting block 58 is staggered with the connecting block 56 and the hinge block 57, and the mounting block 58 is used to install a gas alarm.

[0041] When the location of the gas leak needs to be processed, the maintenance personnel rotate the arc plate 54 to open the arc plate 54, and then tear off the sealing sheet 51, and then buckle the arc plate 54 on the pipeline of the gas generator 471 group. Then the maintenance personnel use bolts to connect the two connecting blocks 56 to close the arc plate 54, and then use an air pump to connect the air intake pipe 55 to inflate the air storage bag 53. During the inflation process, the air storage bag 53 expands. Due to the limiting effect of the arc plate 54, the air storage bag 53 can only expand inwards. During the expansion process of the air storage bag 53, the air storage capsule 52 is squeezed. The colloid stored in the storage capsule 52 is evenly spread on the surface of the pipeline, and then the storage capsule 52 squeezes the colloid from the outside to prevent the colloid from being blown apart by the leaked gas before solidification, resulting in the inability to block the leakage and affecting the maintenance effect; after the blowing is completed, the maintenance personnel use the sealing cover to seal the air inlet pipe 55 to prevent the air storage bag 53 from leaking; then, the maintenance personnel install the gas alarm into the gap between the two mounting blocks 58, and then the maintenance personnel press the buckle on the side wall of the mounting block 58 to clamp the gas alarm, thereby fixing the gas alarm, so that the leakage position can be monitored through the gas alarm.

[0042] In this embodiment, the arc plate 54 is designed with two semicircular shapes and one end is hinged and the other end is connected with bolts and nuts, which is convenient for maintenance personnel to operate and can be quickly opened and closed; the arrangement of the gas storage bag 53 and the gas storage bag 52 can adapt to the gas generator 471 groups of pipelines with different diameters, and can be flexibly installed in the position where leakage prevention treatment is required; and the leakage prevention component 5 is provided with a structure specially used for installing the gas alarm, that is, the gap and the buckle between the two mounting blocks 58, which is convenient for maintenance personnel to fix the gas alarm near the leakage position, realize the key monitoring of the gas leakage situation at this position, timely discover the potential leakage risk, and ensure the safety of gas use.

[0043] A mounting groove is provided on the top of the vehicle body; the fixing module 3 comprises: an inflatable box 31 installed in the mounting groove, and an air outlet is provided on the side wall of the inflatable box 31; a groove is provided on the top of the inflatable box 31, and a sliding block 32 is slidably connected in the groove; a rubber pad can be provided between the sliding block 32 and the inflatable box 31 to achieve sealing between the inflatable box 31 and the sliding block 32, so that when the sliding block 32 rises, air can enter the inflatable box 31, and when the sliding block 32 descends, the air inside the inflatable box 31 is discharged from the air outlet.

[0044] An arc-shaped airbag 33 is installed in the middle of the top of the sliding block 32, and the air inlet end of the arc-shaped airbag 33 is connected to the air outlet of the inflation box 31 through a connecting pipe 36. A limiting plate 35 is installed on one side of the top of the sliding block 32, and an inner fixed airbag 34 is installed on the top of the limiting plate 35. The air inlet end of the inner fixed airbag 34 is connected to the other air outlet of the inflation box 31 through a connecting pipe 36; the arc-shaped airbag 33 is used to fix the arc plate 54 from the surrounding side of the anti-leakage component 5, and the inner fixed airbag 34 is used to fix the mounting block 58 of the anti-leakage component 5.

[0045] When the manipulator 2 carries the anti-leakage component 5 and places it on the top of the fixed module 3, the gravity of the anti-leakage component 5 presses down the sliding block 32, so that the air between the inflation box 31 and the sliding block 32 is discharged from the air outlet to the arc-shaped airbag 33 and the inner fixed airbag 34 respectively, thereby clamping and fixing the mounting block 58 and the arc plate 54 respectively; the anti-leakage component 5 uses its own gravity to press down the sliding block 32, so that the air in the inflation box 31 is discharged into the arc-shaped airbag 33 and the inner fixed airbag 34, so that the arc plate 54 and the mounting block 58 of the anti-leakage component 5 are automatically clamped and fixed, without the need for additional complex operations, thereby improving the fixing efficiency and convenience; the arc plate 54 is fixed from the peripheral side by the arc-shaped airbag 33, and the mounting block 58 is fixed by the inner fixed airbag 34. The multi-directional fixing method can make the anti-leakage component 5 more stable in the mounting groove on the top of the vehicle body, reducing shaking or displacement.

[0046] In addition, an exhaust port is provided at the top of the inner fixed airbag 34, and a sealing block is detachably connected to the exhaust port, and the sealing block is snap-fitted or threadedly connected to the exhaust port; a return spring is connected between the inflation box 31 and the sliding block 32, and when there is no anti-leakage component 5 on the sliding block 32, the sliding block 32 slides upward.

[0047] The detection module 4 includes: a detection box 41 installed on one side of the top of the vehicle body, mounting plates 42 symmetrically installed on both sides of the top of the detection box 41, sampling air bags 43 respectively installed on the sides of the two mounting plates 42 close to each other, and water tanks 44 respectively installed on the sides of the two mounting plates 42 away from each other, an L-shaped plate 46 is arranged between the two sampling air bags 43, and a power component 47 for driving the two sampling air bags 43 to intermittently extend and retract is arranged on the L-shaped plate 46; the sampling air bags 43 extend and retract in the transverse direction; water is stored in the water tank 44, and the liquid outlet end of the water tank 44 is connected to the liquid inlet end of the sampling air bag 43; an air inlet is arranged on the top of the sampling air bag 43, and an air outlet is arranged on the bottom of the sampling air bag 43, and the air outlet is connected to the detection box 41; the detection unit is installed inside or at the bottom of the detection box 41; a cleaning block 48 is slidably installed inside the detection box 41.

[0048] The power assembly 47 includes: a motor 471 fixedly mounted on one side of the L-shaped plate 46, a rotating disk 472 connected to the output end of the motor 471, a guide rod 473 detachably mounted on the rotating disk 472, a waist plate 474 slidably connected to the guide rod 473, a push rod 475 symmetrically connected to both ends of the waist plate 474 in the width direction, and a guide block 476 slidably connected to the push rod 475; the guide block 476 is mounted on the L-shaped plate 46; a waist hole is opened in the middle of the waist plate 474; a cylindrical block matching the waist hole is arranged on the guide rod 473, and is slidably connected to the waist hole through the cylindrical block; a connecting structure is installed at one end of the two push rods 475 away from each other, and the two connecting structures are respectively fixedly connected to the adjacent sampling airbags 43; a filter is arranged between the sampling airbag 43 and the detection box 41 to prevent dust from entering the detection box 41 and affecting the detection results, and at the same time it can also protect the sensors and other components in the detection box 41 and extend their service life.

[0049] When the motor 471 is started, the output end of the motor 471 drives the rotating disk 472 to rotate, thereby driving the guide rod 473 to rotate synchronously, and the guide rod 473 drives the waist plate 474 to slide back and forth horizontally, so that the two push rods 475 intermittently push and pull the sampling air bags 43 on both sides, so that the two sampling air bags 43 intermittently draw air and exhaust air.

[0050] The intermittent suction and exhaust of the sampling airbag 43 can automatically complete the air sampling work and transport the air to the detection box 41; the sampling airbag 43 also compresses the air in the detection box 41, so that the natural gas concentration in the detection box 41 is relatively increased, which is convenient for the sensor to detect the natural gas more accurately, thereby improving the detection effect; the air sent into the detection box 41 can also drive the cleaning block 48 to slide back and forth in the detection box 41 to clean the sensor set in the detection box 41, effectively avoiding the coverage of pollutants such as dust on the sensor, so that the sensor always remains sensitive, and the accuracy and reliability of the detection result are improved; at the same time, the air sent in carries the moisture inside the water tank 44 to the inside of the detection box 41. When the natural gas concentration is high, there is a risk of fire or even explosion. The moisture in the water tank 44 is carried to the inside of the detection box 41. The moisture can reduce the oxygen concentration in the detection box 41 and dilute the natural gas concentration. At the same time, it absorbs heat and prevents the occurrence of combustion reactions, thereby effectively preventing fire accidents caused by excessive natural gas concentration, and greatly improving the safety of the detection process. In this embodiment, a negative pressure fan may be provided at the air outlet of the detection box 41 to absorb air, so as to increase the amount of air entering the detection box 41 .

[0051] The detection box 41 is also connected to a gas tank 45, which stores fuel gas. In order to avoid malfunction of the detection unit or reduction in detection accuracy due to impurities, fuel gas is regularly sprayed into the detection box 41 through the gas tank 45 for detection by the detection box 41. Based on the detection results of the detection box 41, it can be determined whether the detection unit has malfunctioned.
