Description

Technical Field

[0001] The utility model relates to the technical field of gas control and management, in particular to an inspection vehicle used for underground gas pipeline leakage detection. Background Art

[0002] With the acceleration of urbanization and the continuous growth of energy demand, the underground gas pipeline network is becoming increasingly large and complex. While gas, as a clean energy, brings convenience to people's lives and production, its safe transportation and use also face many challenges. Among them, gas pipeline leak detection is a key link in ensuring gas safety. During daily maintenance and inspections of the gas pipeline network, inspection vehicles are needed to detect gas leaks.

[0003] Inspection vehicles are needed for daily maintenance and inspection of gas pipeline networks. Among them, the "A Comprehensive Intelligent Inspection Device for Natural Gas Stations" disclosed with publication number "CN221004523U" has solved many technical drawbacks of the existing technology that is unable to detect whether there is a leak at the connection between two natural gas pipelines.

[0004] However, there are still many defects in the actual use of inspection vehicles with similar structures, such as: it is not convenient to adjust the detection direction according to the use requirements, which makes it difficult to detect overhead pipelines at high places, forming detection blind spots, and it is difficult to accurately obtain information such as gas concentration. At the same time, it is not convenient to scan the pipeline network from multiple angles. For special parts such as elbows and branch interfaces, gas leaks may be missed, resulting in incomplete detection results, limiting the assessment of the overall condition of the pipeline network, making it difficult to cover all areas of the pipeline network, and easily ignoring potential leakage points, posing risks to gas safety. Therefore, in order to solve this problem, there is an urgent need to propose an inspection vehicle for underground gas pipeline leakage detection. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides an inspection vehicle for detecting leakage in underground gas pipelines to solve the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a patrol vehicle for detecting underground gas pipeline leaks, comprising a box body, a driving mechanism for detecting the gas pipeline fixedly mounted on one side of the top of the box body, and an adjustment mechanism for the driving device to adapt to different road surfaces fixedly mounted on one side of the bottom of the box body;

[0007] The driving mechanism includes a shaft seat, an electric rod is movably mounted on the inner side of the shaft seat, a uniform speed motor is fixedly mounted on the output end of the electric rod, an electric push rod is fixedly mounted on the output end of the uniform speed motor, a cross plate is fixedly mounted on the output end of the electric push rod, a gas detector is fixedly mounted on one side of the cross plate, an industrial camera for photographing gas leaks is fixedly mounted below the gas detector, a screw transmission mechanism is fixedly mounted on the top side close to the shaft seat, and a connecting piece is movably mounted on one side of the screw transmission mechanism, and a fixed movable sleeve is movably mounted on one end of the connecting piece for sleeved on the outer side of the electric rod;

[0008] The adjustment mechanism comprises a mounting seat, a micro motor is movably mounted on one side of the mounting seat, and a camera body is fixedly mounted on an output end of the micro motor.

[0009] Preferably, two sets of mounting plates are fixedly installed on one side of the box body, an electric lifting rod is fixedly installed inside the mounting plate, a bearing frame is fixedly installed on the output end of the electric lifting rod, a servo motor is fixedly installed on one side of the bearing frame, and a moving wheel is fixedly installed on the output end of the servo motor.

[0010] Preferably, two sets of fixing brackets are fixedly mounted on one side of the bottom of the box away from the adjustment mechanism, a first driver is fixedly mounted on one side of the fixing bracket, and a tire is fixedly mounted on the output end of the first driver.

[0011] Preferably, two sets of second drivers are fixedly mounted on one side of the bottom of the box body close to the adjustment mechanism, and a universal wheel is fixedly mounted on the output end of the second driver.

[0012] Preferably, two groups of gas sensor probes for detecting gas leakage are fixedly installed on the outer side of the top of the box, and a controller is fixedly installed on the other side of the top of the box.

[0013] Preferably, a protection box is fixedly installed on the outside of the controller, and the bottom of the protection box is fixedly connected to the top of the box body.

[0014] The utility model provides a patrol vehicle for detecting underground gas pipeline leaks. Compared with the existing technology, it has the following advantages:

[0015] 1. The electric rod is energized to drive the uniform speed motor to move the vertical position. The uniform speed motor for vertical position movement can drive the electric push rod to move synchronously to the specified position, and then the electric push rod is energized to drive the gas detector to penetrate into the gas pipe network, so as to adjust the detection height of the gas detector according to the use requirements. The uniform speed motor is energized to drive the electric push rod to rotate. The rotating electric push rod can drive the gas detector to rotate synchronously, so as to facilitate multi-directional investigation and detection of leaks in the gas pipe network. The gas detector can be used in conjunction with the controller to monitor the gas concentration in the area around the gas pipe network, and the industrial camera can be used in conjunction with the controller to record the gas pipeline leak. The screw transmission mechanism is then energized to drive the connecting piece to move the position. The connecting piece for position movement can drive the electric rod to move in an arc position with the shaft seat as the axis, thereby achieving the effect of adjusting the use height and angle of the gas detector, realizing the function of facilitating multi-directional detection of the gas pipe network, increasing the intelligent effect of the device, avoiding the device being easily restricted by the detection orientation, and expanding the scope of application of the device.

[0016] 2. The camera body and the controller are used together to monitor the road surface on which the device is moving. When the controller detects an obstacle on the road, the electric lifting rod is powered on through the wire to drive the servo motor to move vertically, so that the moving wheel moves until it contacts the ground. The servo motor is then powered on to drive the moving wheel to rotate. The rotating moving wheel can drive the device to move its position, realizing the function of climbing over obstacles, expanding the scope of application of the device, avoiding the device being easily restricted by the road surface, and improving the compatibility of the device.
