Description

Technical Field

[0001] The present invention relates to the technical field of natural gas receiving station monitoring, and in particular to an intelligent monitoring device for an LNG receiving station. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gasfield gas, mud volcano gas, coalbed methane, and biogenic gas, etc.). The definition of "natural gas" that people have long used is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. In petroleum geology, it usually refers to oilfield gas and gasfield gas. Its composition is mainly hydrocarbons and contains non-hydrocarbon gases.

[0003] Chinese patent CN216643755U discloses a monitoring device for a liquefied natural gas (LNG) receiving station, including a monitoring camera and a base, and also including a clamping mechanism and a top protection mechanism. The clamping mechanism is composed of a rear plate, a clamping plate, a clamping column, a clamping platform, a vertical groove, a plate groove, a column hole, a triangular plate and a through hole. The rear end of the base is fixedly connected with the clamping plate. A clamping mechanism is provided at the base below the monitoring camera. After the triangular plate is first attached to the outer wall of the receiving station, expansion bolts are driven into the wall through the through holes to fix the triangular plate. At this time, there is a connection relationship between the rear plate, the clamping plate and the clamping column at the base, which can be well engaged in the vertical groove, the plate groove and the column hole in turn. The base is held and lifted upward, so that the rear plate, the clamping plate and the clamping column are detached from the vertical groove, the plate groove and the column hole, and the disassembly of the monitoring camera can be completed conveniently, which greatly facilitates the disassembly, assembly and maintenance of the monitoring camera.

Most of these pipelines are relatively long. The positioning and installed surveillance cameras can only monitor the conditions of part of the transmission pipelines, making it difficult to conduct detailed inspections and monitoring of the long transmission pipelines.

[0053] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] like Figures 1 to 12 As shown:

[0055] An intelligent monitoring device for an LNG receiving station includes an intelligent walking device that walks on a natural gas pipeline 1, on which a monitoring camera 2 is also installed. The intelligent walking device includes an adsorption support frame 3 adsorbed on the outside of the natural gas pipeline 1, a multi-directional walking device 4 for adjusting movement is installed at the bottom of the adsorption support frame 3, the multi-directional walking device 4 is in contact with the outer wall of the natural gas pipeline 1, an angle detection device 6 is installed at the center of the adsorption support frame 3, a flipping device 5 for turning over obstacles is installed on the adsorption support frame 3, and the adsorption support frame 3 is also provided with a solar panel 7 for collecting energy.

[0056] When it is necessary to inspect a long natural gas pipeline 1, the inspector places the intelligent walking device on the natural gas pipeline 1, and the driving end of the multi-directional walking device 4 will conflict with the outer wall of the natural gas pipeline 1. The inspector adjusts the adsorption support frame 3 of the intelligent walking device according to the diameter of the natural gas pipeline 1, so that the adsorption support frame 3 can be adsorbed and fixed on the natural gas pipeline 1. The adsorption support frame 3 is adsorbed and fixed on the natural gas pipeline 1. When the inspector needs to inspect the natural gas pipeline 1, the inspector remotely controls the multi-directional walking device 4 to drive the adsorption support frame 3 to move along the natural gas pipeline 1. When the adsorption support frame 3 moves, it drives the monitoring camera 2 to move synchronously. The inspector inspects and monitors the natural gas pipeline 1 through the monitoring camera 2. When it is necessary to check the lower side of the natural gas pipeline 1, the inspector can By driving the adsorption support frame 3 to rotate and adjust on the natural gas pipeline 1 through the multi-directional walking device 4, the observation angle of the monitoring camera 2 can be effectively changed to improve the monitoring and observation effect. The angle detection device 6 can detect the rotation angle of the adsorption support frame 3, which is convenient for the patrol personnel to remotely and accurately control and adjust the angle of the adsorption support frame 3. The solar panel 7 on the adsorption support frame 3 can effectively recycle solar energy. When the adsorption support frame 3 moves to the interface of the natural gas pipeline 1 and cannot pass directly, it contacts the natural gas pipeline 1 through the flipping device 5 and performs adsorption positioning, and then the adsorption support frame 3 is unfixed, and the flipping device 5 drives the adsorption support frame 3 to flip and cross the obstacle at the interface of the natural gas pipeline 1 to continue to move forward for patrol. This application can effectively improve the efficiency of monitoring and patrol, while saving manpower.

[0057] like Figure 1 and Figure 3 As shown:

[0058] The adsorption support frame 3 comprises a horizontal mounting frame 31 , both ends of which are provided with a pressing adsorption mechanism 32 , and one end of the pressing adsorption mechanism 32 away from the horizontal mounting frame 31 is symmetrically provided with a plurality of universal balls 33 .

[0059] When the horizontal mounting frame 31 needs to be stably adsorbed on the side of the natural gas pipeline 1, the inspector places the horizontal mounting frame 31 on the natural gas pipeline 1, and the multi-directional walking device 4 at the bottom of the horizontal mounting frame 31 will conflict with the outer wall of the natural gas pipeline 1. The inspector adjusts the pressure adsorption mechanism 32 according to the diameter of the natural gas pipeline 1 to adjust the pressure adsorption mechanism 32 to wrap the outer wall of the natural gas pipeline 1. The pressure adsorption mechanism 32 is used to contact the surface of the natural gas pipeline 1 through the universal ball 33. The universal ball 33 is convenient for reducing the friction of the conflict and facilitating the movement of the position of the horizontal mounting frame 31. At the same time, the pressure adsorption mechanism 32 can be stably adsorbed on the outside of the natural gas pipe through magnetic adsorption.

[0060] like Figure 3 and Figure 4 As shown:

[0061] The pressing and adsorption mechanism 32 includes a first mounting seat 321 installed on the side of the horizontal mounting frame 31, a rotating shaft 322 is installed on the first mounting seat 321, the rotating shaft 322 is covered with anti-slip teeth, an arc-shaped bracket 323 is also installed on the side of the rotating shaft 322, a first electromagnetic adsorption block 324 is installed at one end of the arc-shaped bracket 323 away from the rotating shaft 322, and a locking mechanism is also installed on the first mounting seat 321.

[0062] When the horizontal mounting frame 31 needs to be stably adsorbed on the side of the natural gas pipeline 1, the inspector places the horizontal mounting frame 31 on the natural gas pipeline 1, and the inspector adjusts the angle of the arc bracket 323 on the first mounting seat 321 according to the diameter of the natural gas pipeline 1 and wraps the outer wall of the natural gas pipeline 1, so that the universal ball 33 is in conflict with the natural gas pipeline 1. After the arc bracket 323 is adjusted, the inspector locks the rotating shaft 322 into position through the locking mechanism, so that the arc bracket 323 is positioned to maintain the adjusted shape, and the first electromagnetic adsorption block 324 can generate an electromagnetic adsorption force for stably adsorbing the outer wall of the natural gas pipeline 1.

[0063] It should be noted that the locking mechanism includes a threaded adjustment rod 325 mounted on the first mounting seat 321, a pressing block 326 is mounted on the threaded adjustment rod 325, and a pressing bayonet is provided on the pressing block 326. After the arc bracket 323 is adjusted, the inspector rotates the threaded adjustment rod 325, and the threaded adjustment rod 325 rotates to push the pressing bayonet of the pressing block 326 to contact and lock the rotating shaft 322, thereby effectively ensuring the stability of the adjustment.

[0064] like Figure 3 and Figure 5 As shown:

[0065] The multi-directional walking device 4 includes a second mounting seat 41 installed on a horizontal mounting frame 31, a plurality of springs 42 are provided between the horizontal mounting frame 31 and the second mounting seat 41, a second electromagnetic adsorption block 43 is provided at the bottom of the second mounting seat 41, a walking drive device 45 is installed at the axial position of the second mounting seat 41, and a rotation adjustment mechanism 44 for adjusting the walking direction of the walking drive device 45 is also installed on the second mounting seat 41.

[0066] When it is necessary to inspect and test a long natural gas pipeline 1, the inspector places the intelligent walking device on the natural gas pipeline 1, and the driving end of the multi-directional walking device 4 will conflict with the outer wall of the natural gas pipeline 1. The inspector adjusts the adsorption support frame 3 of the intelligent walking device according to the diameter of the natural gas pipeline 1, so that the adsorption support frame 3 can be adsorbed and fixed on the natural gas pipeline 1. When the adsorption support frame 3 is adsorbed and fixed on the natural gas pipeline 1, the spring 42 between the horizontal mounting frame 31 and the second mounting seat 41 can effectively push the walking driving device 45 to conflict with the outer wall of the natural gas pipeline 1, and the second electromagnetic adsorption block 43 on the second mounting seat 41 can generate a magnetic attraction to make the walking driving device When the travel drive device 45 contacts the outer wall of the natural gas pipeline 1 and needs to drive the monitoring camera 2 to walk along the natural gas pipeline 1 for inspection and monitoring, the travel drive device 45 rotates to drive the adsorption support frame 3 to move horizontally along the natural gas pipeline 1. When the adsorption support frame 3 moves, it drives the monitoring camera 2 to move synchronously for inspection. When it is necessary to check the lower side of the natural gas pipeline 1, the travel direction of the travel drive device is adjusted by rotating the adjustment mechanism 44, so that the travel direction of the travel drive device 45 is adjusted to the horizontal direction. The travel drive device 45 adjusted to the horizontal direction can drive the adsorption support frame 3 to rotate around the natural gas pipeline 1 to adjust the angle, which can effectively change the observation angle of the monitoring camera 2 and improve the monitoring and observation effect.

[0067] like Figure 5 and Figure 6 As shown:

[0068] The rotation adjustment mechanism 44 includes a rotation mounting block 441 installed on the second mounting seat 41, a mounting cavity is provided on the rotation mounting block 441, a limit gear ring 442 is installed on the rotation mounting block 441, and the rotation adjustment mechanism 44 also includes a first rotation driver 443 installed on the second mounting seat 41, a first driving gear 444 is installed on the rotation of the first rotation driver 443, and the first driving gear 444 is meshed with the limit gear ring 442.

[0069] A limiting lever is provided on the limiting gear ring 442, and the first rotating driver 443 is preferably a servo motor. When the walking direction of the travel drive device 45 needs to be adjusted, the servo motor drives the first driving gear 444 to rotate, and when the first driving gear 444 rotates, it drives the limiting gear ring 442 to synchronously adjust and rotate, and when the limiting gear ring 442 rotates, it drives the rotating mounting block 441 to rotate. The limiting lever on the limiting gear ring 442 is used to cooperate with the second mounting seat 41 for limiting blocking, effectively ensuring the rotation adjustment angle of the limiting gear ring 442, and when the rotating mounting block 441 rotates, it can drive the travel drive device 45 to synchronously rotate and adjust to change the walking direction.

[0070] like Figures 5 to 8 As shown:

[0071] The travel drive device 45 includes an anti-skid wheel 451 installed on the rotating mounting block 441, and a driven wheel 453 is also installed on the anti-skid wheel 451. The travel drive device 45 also includes a second rotating driver 454 installed on the rotating mounting block 441, and a driving wheel 455 is installed on the rotating end of the second rotating driver 454. A transmission belt 452 is provided on the driving wheel 455 and the driven wheel 453.

[0072] The inspectors place the intelligent walking device on the natural gas pipeline 1, and the anti-skid wheel 451 will conflict with the natural gas pipeline 1. The second rotary driver 454 is preferably a servo motor. When it is necessary to drive the adsorption support frame 3 to move, the servo motor drives the driving wheel 455 to rotate. When the driving wheel 455 rotates, it drives the driven wheel 453 to rotate through the transmission belt 452. When the driven wheel 453 rotates, it drives the anti-skid wheel 451 to rotate. When the anti-skid wheel 451 rotates, it can drive the multi-directional walking device 4 to move on the natural gas pipeline 1.

[0073] like Figure 1 and Fig. 9 As shown:

[0074] The turning device 5 includes a turning frame 51 symmetrically mounted on the horizontal mounting frame 31 . A positioning adsorption head 52 is mounted on one end of the turning frame 51 away from the horizontal mounting frame 31 . The turning frame 51 is synchronously rotated by a synchronous driving device 53 .

[0075] When the adsorption support frame 3 moves to the interface of the natural gas pipeline 1 and cannot pass directly, the multi-directional walking device 4 drives the adsorption support frame 3 to move to the interface of the natural gas pipeline 1, and drives the flip frame 51 to rotate and adjust through the synchronous driving device 53. When the flip frame 51 rotates, it drives the positioning adsorption head 52 to cross the interface of the natural gas pipeline 1, and the positioning adsorption head 52 is adsorbed and fixed to the outer wall of the natural gas pipeline 1. At the same time, the first electromagnetic adsorption block 324 on the adsorption support frame 3 and the second electromagnetic adsorption block 43 of the multi-directional walking device 4 are both cancelled. The synchronous driving device 53 continues to rotate, which causes the flip frame 51 to support the adsorption support frame 3 to flip over the interface of the natural gas pipeline 1, so that the adsorption support frame 3 moves to another section of the natural gas pipeline 1.

[0076] like Fig. 9 and Fig.11 As shown:

[0077] The positioning adsorption head 52 comprises a vertical rotating block 521 mounted on the flip frame 51 , on which a resistance column 522 is symmetrically mounted, inside of which a third electromagnetic adsorption block 523 is mounted, and outside of which an anti-skid layer is provided.

[0078] A waist-shaped groove is provided on the vertical rotating block 521, and the vertical rotating block 521 is connected to the flip frame 51 through the waist-shaped groove. Under the influence of gravity, the resistance column 522 at the lower end of the vertical rotating block 521 is always vertically downward. When the flip frame 51 rotates, it drives the vertical rotating block 521 to rotate. When the vertical rotating block 521 rotates, it drives the vertically downward resistance column 522 to collide with the natural gas pipeline 1. After the resistance column 522 collides with the natural gas pipeline 1, the third electromagnetic adsorption block 523 generates a magnetic attraction force, and the resistance column 522 is adsorbed and fixed to the natural gas pipeline 1 through the magnetic attraction force. The anti-slip layer on the resistance column 522 can increase the stability of the adsorption and fixation.

[0079] like Fig. 9 and Fig.10 As shown:

[0080] The synchronous drive device 53 includes a rotating rod 531 installed on the horizontal mounting frame 31, and synchronous gears 532 are installed at both ends of the rotating rod 531. The synchronous drive device 53 also includes a first driven gear 533 installed on the flip frame 51, and a transmission chain 534 is sleeved on the synchronous gear 532 and the first driven gear 533. A second driven gear 537 is also installed on the rotating rod 531. The synchronous drive device 53 also includes a third rotating driver 535 installed on the horizontal mounting frame 31, and a second driving gear 536 is installed on the rotating end of the third rotating driver 535. The second driving gear 536 is meshed with the second driven gear 537.

[0081] When it is necessary to flip the adsorption support frame 3, the third rotation driver 535 is preferably a servo motor, which drives the second driving gear 536 to rotate. When the second driving gear 536 rotates, it drives the second driven gear 537 to rotate synchronously. When the second driven gear 537 rotates, it drives the rotating rod 531 to rotate synchronously. When the rotating rod 531 rotates, it drives the synchronous gear 532 to rotate synchronously. When the synchronous gear 532 rotates, it drives the first driven gear 533 to rotate synchronously through the transmission chain 534. When the first driven gear 533 rotates, it drives the flip frame 51 to rotate synchronously.

[0082] like Figure 3 and Fig.12 As shown:

[0083] The angle detection device 6 includes a fixed mounting block 61 mounted on the horizontal mounting frame 31 . A mounting groove is provided at the axis of the fixed mounting block 61 . A plurality of sensors 63 are provided on the inner wall of the mounting groove. A rotating pointer 62 is also installed inside the mounting groove.

[0084] The inspectors use the monitoring camera 2 to inspect and monitor the natural gas pipeline 1. When it is necessary to check the lower side of the natural gas pipeline 1, the inspectors can drive the adsorption support frame 3 to rotate and adjust on the natural gas pipeline 1 through the multi-directional walking device 4, which can effectively change the observation angle of the monitoring camera 2 to improve the monitoring and observation effect. When the adsorption support frame 3 rotates, it drives the fixed mounting block 61 to rotate synchronously. When the fixed mounting block 61 rotates, the rotating pointer 62 always maintains a vertical falling state. The rotating pointer 62 is preferably made of plastic. The sensor 63 can detect the position of the rotating pointer 62. According to the sensor 63, the position of the adsorption support frame 3 on the natural gas pipeline 1 can be effectively detected.

[0085] Specific working principle:

[0086] The inspector places the intelligent walking device on the natural gas pipeline 1, and the driving end of the multi-directional walking device 4 will conflict with the outer wall of the natural gas pipeline 1. The inspector adjusts the adsorption support frame 3 of the intelligent walking device according to the diameter of the natural gas pipeline 1, so that the adsorption support frame 3 can be adsorbed and fixed on the natural gas pipeline 1. The adsorption support frame 3 is adsorbed and fixed on the natural gas pipeline 1. When the inspector needs to inspect the natural gas pipeline 1, the inspector remotely controls the multi-directional walking device 4 to drive the adsorption support frame 3 to move along the natural gas pipeline 1. When the adsorption support frame 3 moves, it drives the monitoring camera 2 to move synchronously. The inspector inspects and monitors the natural gas pipeline 1 through the monitoring camera 2. When it is necessary to check the lower side of the natural gas pipeline 1, the inspector can drive the adsorption support frame 3 on the natural gas pipeline through the multi-directional walking device 4. 1 can be rotated and adjusted, which can effectively change the observation angle of the monitoring camera 2 and improve the effect of monitoring and observation. The angle detection device 6 can detect the rotation angle of the adsorption support frame 3, which is convenient for the patrol personnel to remotely and accurately control and adjust the angle of the adsorption support frame 3. The solar panel 7 on the adsorption support frame 3 can effectively recycle solar energy. When the adsorption support frame 3 moves to the interface of the natural gas pipeline 1 and cannot pass directly, it contacts the natural gas pipeline 1 through the flipping device 5 and performs adsorption positioning, and then the adsorption support frame 3 is unfixed. The flipping device 5 drives the adsorption support frame 3 to flip and move and cross the obstacle at the interface of the natural gas pipeline 1 to continue to patrol. The intelligent walking device drives the camera 2 to patrol and monitor the natural gas pipeline, which can effectively improve the efficiency of monitoring and inspection, and save manpower at the same time.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
