Description

Technical Field

[0001] The utility model belongs to the field of crude oil monitoring equipment, and specifically relates to a crude oil leakage monitoring device carried by an unmanned aerial vehicle and a unmanned aerial vehicle monitoring system. Background Art

[0002] With the increasing demand for energy utilization, the demand for crude oil exploitation and utilization is also increasing. In the process of crude oil exploitation, transportation, loading and unloading, processing and use, unexpected accidents, abnormal operation or equipment maintenance can easily lead to the spillage and abnormal discharge of crude oil, which have a negative impact on soil, water resources, flora and fauna, and human health. Therefore, the monitoring of crude oil leakage has become an indispensable part of the process of crude oil exploitation and utilization.

[0003] At present, there are three main ways to monitor crude oil spills, namely satellite image monitoring, drone image monitoring (visible light) and manual inspections. Among them, the manual inspection method has great limitations, high labor costs, and is limited by limited patrol routes. It cannot achieve large-scale monitoring, nor can it fully meet the monitoring needs in certain special operation scenarios. It has obvious defects and is gradually being eliminated. Satellite image monitoring is widely used because of its diverse monitoring methods and high collection efficiency; however, the resolution of satellite images is low and is affected by ground buildings and vegetation. It is difficult to achieve for scattered and small amounts of crude oil spills. It cannot effectively meet the monitoring needs of accurately identifying crude oil leaks in the early stages of crude oil leaks, and there are certain application limitations.

[0004] In contrast, drone image monitoring is a more commonly used method for monitoring crude oil spills. It is highly flexible and environmentally compatible, and can meet the needs of crude oil spill monitoring in various application environments. However, for existing drone image monitoring methods, most drone platforms are equipped with visible light cameras, which have limited ability to collect information on crude oil spills, and the collection efficiency and accuracy are usually reduced; moreover, the cameras carried in existing drone platforms are usually fixed cameras, which are generally dedicated to special aircraft, resulting in limited monitoring tasks that can be performed and low flexibility of use.

[0049] Example:

[0050] See also Figure 1~Figure 5The crude oil leakage monitoring device onboard a drone in the preferred embodiment of the utility model is used to be carried on a drone, and the drone is carried to fly to the monitored area to monitor the crude oil leakage. For the monitoring device in the preferred embodiment, it can be carried on various existing drones.

[0051] Specifically, the crude oil leakage monitoring device onboard a UAV in the preferred embodiment includes a first rotating bracket 1 , a second rotating bracket 2 and a monitoring unit 3 .

[0052] like Figure 2 As shown in the figure, the first rotating bracket 1 in the preferred embodiment has a rod-shaped main body, the two ends of which are respectively a first rotating connecting end 101 and a second rotating connecting end 102, and the central axes of the two rotating connecting ends are arranged to intersect.

[0053] In more detail, the first rotating connection end 101 is used to connect with the airborne connection position on the drone, and includes a quick-connect interface ring 103, a quick-connect guide ring 104 and a direction motor support 105 coaxially arranged on the first rotating connection end 101. The direction motor support 105 is fixedly arranged at the end of the first rotating connection end 101, and is used to correspondingly install the first direction motor; one end of the quick-connect guide ring 104 is fixedly connected to one end of the quick-connect interface ring 103, and the other end thereof is assembled and connected with the output shaft of the first direction motor through an adapter, so that the first direction motor can drive the direction motor support 105 to rotate around the axis relative to the quick-connect guide ring 104.

[0054] In a preferred embodiment, the adapter disposed between the output shaft of the first direction motor and the quick-connect guide ring 104 is a gear-gear ring assembly. At this time, a gear ring is disposed on the inner circumferential wall surface of the quick-connect guide ring 104 in the annular direction, and a gear is coaxially fixed to the output shaft of the first direction motor. The gear is meshed with the gear ring, and the main body of the first rotating bracket 1 can be rotated around the axis relative to the quick-connect guide ring 104 by rotating the output shaft of the first direction motor.

[0055] In actual settings, in order to avoid axial separation between the first direction motor and the quick-connect guide ring 104, it is preferred to configure the quick-connect guide ring 104 to be open at one end and semi-closed at the other end, with the open end fixedly connected to the quick-connect interface ring 103, the gear is coaxially embedded in the quick-connect guide ring 104, and is axially limited after engaging with the gear ring, and the output shaft of the first direction motor extends into the quick-connect guide ring 104 and is coaxially fixedly connected to the gear.

[0056] Of course, in addition to the above-mentioned method, other rotational connection forms can also be provided as required to realize the rotational connection between the quick-connect guide ring 104 and the output shaft of the first direction motor, which will not be elaborated here.

[0057] Furthermore, the end of the quick-connect interface ring 103 that is not connected to the quick-connect guide ring 104 is protruded for quick connection with the airborne connection position of the drone. In a preferred embodiment, the outer periphery of the quick-connect interface ring 103 is provided with a plurality of locking protrusions along the circumferential direction to assist in achieving the connection between the quick-connect interface ring 103 and the airborne connection position.

[0058] In more detail, the second rotating connection end 102 is arranged at the other end of the main body of the first rotating bracket 1 away from the first rotating connection end 101 , and is provided with a corresponding connecting piece corresponding to the rotating connection of the second rotating bracket 2 .

[0059] In actual configuration, any rotating connection end is spaced a certain distance from the other rotating connection end in a direction perpendicular to the central axis thereof, that is, the main body of the first rotating bracket 1 is arranged to extend obliquely between the two rotating connection ends. In this configuration, when the monitoring unit 3 is subsequently installed, the monitoring unit 3 is located at the intersection of the central axes of the two rotating connection ends.

[0060] In more detail, in a specific preferred embodiment, the central axis of the first rotating connection end 101 is orthogonal to the central axis of the second rotating connection end 102. With this arrangement, the rotation control of the monitoring unit 3 in the orthogonal plane can be achieved.

[0061] For example, when the central axis of the first rotating connection end 101 extends vertically, the first rotating bracket 1 can be rotated and adjusted in the horizontal plane relative to the drone; at this time, the central axis of the second rotating connection end 102 extends in the horizontal direction, which is equivalent to that the second rotating bracket 2 can be rotated and adjusted in the vertical plane relative to the second rotating connection end 102.

[0062] Furthermore, if Figure 3 As shown in the figure, the second rotating bracket 2 in the preferred embodiment is of a C-shaped structure or a U-shaped structure, which includes a rotating connection part 201 located in the middle and pitch connection ends respectively arranged at the two free ends of the second rotating bracket 2, namely the first pitch connection end 202 and the second pitch connection end 203 as shown in the figure.

[0063] Specifically, the rotation connection part 201 is disposed on a side of the second rotation bracket 2 away from the two pitch connection ends, and is coaxially rotationally connected to the second rotation connection end 102 , and can rotate around the axis relative to the second rotation connection end 102 .

[0064] More specifically, the rotation connection part 201 is connected to the second rotation connection end 102 via the output shaft of the second direction motor. In actual configuration, the body of the second direction motor is fixedly mounted on the second rotation connection end 102 or the rotation connection part 201; accordingly, the output shaft end of the second direction motor is fixedly connected to the rotation connection part 201 or the second rotation connection end 102.

[0065] With such arrangement, the second directional motor can be controlled to rotate the second rotating bracket 2 relative to the end of the first rotating bracket 1 , thereby realizing the left-right swing of the monitoring unit 3 relative to the first rotating bracket 1 .

[0066] Furthermore, if Figure 4 As shown in the figure, the monitoring unit 3 in the preferred embodiment includes a box-shaped shell 301, and the two sides of the shell 301 are respectively provided with pitch connection parts 302 corresponding to the rotation connection with the pitch connection end, so that the two sides of the monitoring unit 3 can be coaxially rotationally connected with the corresponding pitch connection end through the pitch connection parts 302.

[0067] In actual configuration, a third direction motor is provided between at least one pitch connection part 302 and the corresponding pitch connection end, and its configuration form is the same as the rotation connection form between the rotation connection part 201 and the second rotation connection end 102, and will not be elaborated here.

[0068] In a specific preferred embodiment, one pitch connection part 302 is connected to the corresponding pitch connection end via an output shaft of a third direction motor, and another pitch connection part 302 is rotationally connected to the corresponding pitch connection end via a rotation shaft.

[0069] Of course, it is understandable that third directional motors may be respectively provided corresponding to the two pitch connection parts 302 . In this case, the two third directional motors may be synchronously controlled to achieve the pitch movement of the monitoring unit 3 relative to the second rotating bracket 2 .

[0070] Furthermore, in the preferred embodiment, a monitoring lens 303 and a core control board 308 are combined and arranged in the housing 301 , and the two are electrically connected, so that the monitoring lens 303 can perform image acquisition under the control of the core control board 308 .

[0071] At the same time, corresponding to the setting of the monitoring lens 303, a data transmission module and / or a data storage module (not shown in the figure) is preferably also provided in the housing 301. By using the setting of the data transmission module, the monitoring lens 303 can be interconnected with the signal transmission system of the drone in real time, and then the collected image data can be transmitted back to the control terminal in real time. By using the electrical connection between the data storage module and each lens module, the data collected by the monitoring lens 303 can be stored in real time, which is convenient for data backup and monitoring applications in environments with poor communication signals.

[0072] In more detail, the monitoring lens 303 in the preferred embodiment is as follows: Figure 4 As shown in , it is preferably arranged to protrude from the surface of the housing 301 , and includes a glass mask 304 and a plurality of lens modules encapsulated in the glass mask 304 .

[0073] In actual configuration, a plate-shaped lens bracket 307 is provided to correspond to the installation of multiple lens modules, and each lens module is installed on the lens bracket 307; accordingly, Figure 5 The core control board 308 shown in FIG. 3 is encapsulated in the housing 301 through the lens bracket 307 .

[0074] In more detail, the monitoring lens 303 in the preferred embodiment includes at least one visible light lens module 305 and multiple multi-spectral lens modules 306. The visible light lens module 305 can be used to shoot within the optical band, and the multi-spectral lens module 306 can be used to shoot within multiple optical bands, especially shooting within the non-visible light band.

[0075] In actual configuration, the plurality of lens modules are preferably arranged in an array on the lens support 307 .

[0076] In addition, among the plurality of multi-spectral lens modules 306, at least two multi-spectral lens modules 306 have different working ranges / shooting bands. Figure 4 In the preferred embodiment shown, the shooting bands of each multi-spectral lens module 306 are different, so that shooting within the full band range can be achieved as much as possible, fully ensuring the accuracy of the monitoring results.

[0077] More specifically, in actual configuration, the lens modules in the monitoring lens 303 are arranged in the form of N (multi-spectral lens module) + 1 (visible light lens module), where N is an integer greater than 1. Figure 4 In the preferred embodiment shown, the lens modules are arranged in an 8+1 arrangement, forming a 3×3 module arrangement.

[0078] Of course, according to the actual setting requirements, the arrangement of the lens modules in the monitoring lens 303 can be adjusted or changed accordingly, which will not be elaborated here.

[0079] Preferably, for the multi-spectral lens module 306 in the preferred embodiment, the wavelength range of each lens module when actually working can be determined according to needs, which will not be elaborated here.

[0080] In actual settings, the motors in each direction are preferably connected to the control system of the drone in communication, so that the motors in each direction can respectively receive control instructions issued by the control system of the drone, and then complete the corresponding action process.

[0081] The UAV-mounted crude oil leakage monitoring device in the utility model has a compact structure and is easy to control. It can accurately monitor crude oil leakage by being carried by a UAV. By utilizing the corresponding settings of the two rotating brackets and the combination of a multi-spectral lens and a visible light lens, the comprehensiveness and accuracy of crude oil leakage monitoring are effectively guaranteed, and the utility model has good practical value.

[0082] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
