Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety monitoring and safety facility transformation of natural gas stations, and specifically relates to an intelligent inspection system for compressor rooms in natural gas stations. Background Art
[0002] Compressors are mainly used to pressurize and transport upstream natural gas to downstream, ensuring the continuous operation of the natural gas pipeline network. Due to the complex structure of the compressor, the large number of supporting facilities and equipment, and the complex pipelines, natural gas leaks are likely to occur. In addition, the uninterrupted operation of the equipment can easily lead to high temperatures in various components. Once a natural gas leak occurs, it will provide an ignition source for combustibles, which can easily cause fire and explosion accidents. Therefore, real-time close-range inspections and dynamic monitoring in the compressor room are crucial.
[0003] The existing natural gas compressor monitoring methods still need to be improved as follows:
[0004] First, most compressor monitoring devices are equipped with gas detectors, temperature detectors, etc., but they are all installed next to the compressor, and the installation point is a certain distance away from the key parts of the compressor equipment. Once natural gas leaks, gas leakage monitoring cannot be achieved immediately, resulting in a "time difference" in eliminating the dangerous source. If the monitoring equipment is installed around the key parts, it will not only be inconvenient for operators to operate the equipment, but also because the compressor has many key parts, installing monitoring equipment for each key part will greatly increase the investment cost.
[0005] Second, regarding the existing compressor monitoring instruments, most compressors are equipped with gas detectors and temperature detectors, but lack harmful gas monitoring equipment and smoke monitoring equipment. The monitoring indicators are not comprehensive, resulting in biased judgments on dangers and accident consequences. Among them, harmful gas monitoring equipment can be used to monitor gases such as carbon monoxide, hydrogen sulfide and hydrogen. This is because the natural gas pressurized by the compressor contains not only methane, but also gases such as carbon monoxide, hydrogen sulfide and hydrogen. Therefore, it is also necessary to monitor the above gases to improve the accuracy of natural gas leakage monitoring; smoke monitoring equipment can be used to monitor smoke particles in the air. This is because natural gas stations have living auxiliary rooms such as kitchens. Daily cooking smoke can provide an ignition source for natural gas, leading to fires and explosions. Therefore, it is necessary to monitor smoke particles in the air.
[0006] Third, once a natural gas leak occurs in an existing compressor, natural ventilation is required to reduce the concentration of the leaked natural gas. This is not only time-consuming and increases the probability of flammable and explosive incidents, but also relies solely on monitoring instruments at a long distance to determine the leakage content in the air, which is not conducive to operators to conduct timely inspections and maintenance. Especially during the peak winter transportation period, the compressor unit needs to continuously supply pressurized air to the downstream, and compressor shutdown will cause huge losses. Utility Model Content
[0007] In view of this, the utility model proposes an intelligent inspection device for a natural gas station compressor room, which is used to solve the problems of existing intelligent inspection devices such as the inability to monitor at close range, incomplete monitoring data, and difficulty in handling when leakage occurs.
[0008] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0010] The travel wheel is arranged on the inspection track, the upper end of the telescopic rod is connected to the travel wheel, and the lower end is connected to the driving mechanism;
[0011] The suction mechanism includes an air suction pipe, an air suction machine and an air storage tank. The air suction machine is arranged outside the robot box, and the air storage tank is arranged inside the robot box. The air suction pipe is connected to the inlet of the air suction machine, and the outlet of the air suction machine is connected to the inlet of the air storage tank through a ventilation pipe.
[0012] Furthermore, the obstacle avoidance mechanism includes laser ranging sensors arranged at the four corners of the bottom of the robot box, and the laser ranging sensors are connected to the monitoring terminal through the first communication module.
[0013] Furthermore, the driving mechanism is a motor, specifically including a walking motor, a rotating motor, and a telescopic motor.
[0014] Furthermore, the monitoring mechanism includes a wind speed sensor, a harmful gas sensor, a temperature and humidity sensor, a dust sensor, an oxygen sensor and a smoke sensor, and each sensor is connected to the monitoring terminal via a second communication module.
[0015] Furthermore, a cloud server is included, the monitoring terminal is connected to the cloud server, an encryption module is provided on the monitoring terminal, and a decryption module is provided on the cloud server.
[0016] The beneficial effects of the utility model are as follows:
[0017] The utility model realizes close-range monitoring of key parts of the compressor through the coordinated arrangement of the driving mechanism and the inspection track, effectively adapts to the characteristics of the compressor equipment being complex and having many components, and monitors the environmental conditions of different spaces of key parts of the compressor unit in an all-round and multi-angle manner; the arrangement of the suction mechanism can promptly deal with emergency situations when leakage occurs, and prevent explosions caused by natural gas leakage and air mixing to the explosion limit; in addition, the distance from the robot body to the compressor equipment is judged by the laser ranging sensor in the obstacle avoidance mechanism. Once the set parameters are exceeded, the microcontroller can control the driving mechanism to drive the walking wheels away from the compressor equipment, thereby realizing protection and close-range monitoring of the utility model and the compressor equipment.
[0018] The technical solution provided by the utility model has a simple structure, reasonable design, small size and low cost. It can acquire environmental parameters such as temperature and humidity, wind speed, oxygen concentration, harmful gases, combustible gases, dust particles, etc., and can upload monitoring data in real time to realize all-round inspection, improve data transmission security and storage security, and facilitate preventive measures.
