Description

Technical Field

[0001] The utility model relates to the technical field of natural gas stations, in particular to an unmanned inspection device for natural gas stations. Background Art

[0002] As an LNG production station, the current common LNG production station team operation personnel configuration is mostly 3 people, among which 1 person is required to be on duty at the central control panel, 1 person is required to patrol the station and inspect the process operation post, and 1 person is required to be at the station gate. At least 2 people are required for daily equipment maintenance in the station, and after the LNG tank truck arrives at the station, the gate guard needs to transfer to the unloading operation, at which time the station gate will be unmanned.

[0003] If there are tank trucks coming again or during maintenance, materials are collected from the material yard, or outsiders enter the station for external inspection, and some production materials and maintenance equipment are stored in the booth, they cannot be controlled in time. If more personnel are added, each team needs to add 1 person, a total of 4 people per shift, which will increase the manpower cost of the gas station, and the cost-effectiveness is low. In addition, under the condition of normal supply of pipeline gas source, the normal workload of the entrance gate is greatly reduced. There is a waste of time to configure one person on duty, and there is a possibility of mismanagement if no one is configured.

[0004] The existing Chinese patent (CN117208249A) discloses an unmanned inspection device for a natural gas station, including a drone body, a gas leak detector in the drone body, and the gas leak detector is installed on a longitudinal slider, the longitudinal slider is sleeved on a longitudinal screw rod and a longitudinal guide rod, the longitudinal screw rod and the longitudinal guide rod are installed on a support seat, the support seat is installed on a transverse moving plate, and the transverse moving plate is sleeved on the transverse screw rod and the transverse guide rod. The beneficial effect of the present invention is that the gas leak detector can be moved to any position relative to the drone body, and can extend outward a certain distance, so as to facilitate detection of small corners in the natural gas station.

[0005] However, the gas leakage detector in the above technical solution can only be adjusted horizontally and vertically, but cannot be adjusted at an angle. In some narrow corners, it cannot be inserted for detection, so manual inspection is still required, which affects the comprehensiveness of unmanned inspection. Utility Model Content

The rotation of the first servo motor 3 and the second servo motor 6 can adjust the angle of the natural gas monitor 8, so that the natural gas monitor 8 can be inserted into a narrow monitoring area, replacing manual inspections and improving the comprehensiveness of unmanned inspections.
