Description

Technical Field

[0001] This application relates to the technical field of early warning, and specifically relates to a safety early warning device for long-distance natural gas pipelines. Background Art

[0002] Long-distance natural gas pipelines are the main means of natural gas transportation. Their safe and stable operation is of great significance for ensuring energy supply and social and economic development. The pipelines pass through various complex terrains and climatic environments along the way and may be affected by natural disasters such as floods, landslides, and collapses, as well as human damages such as misoperations during third-party construction and malicious drilling and oil theft. Setting up a safety early warning device can monitor and give early warnings of these potential threats in real time, reducing the possibility of accidents.

[0003] Patent No. CN 221483385 U discloses a safety early warning device for long-distance natural gas pipelines. By setting warning lights on the outer surface of the pipeline main body to warn the external environment, the movable plate rotates to drive the support rod and the elastic warning belt to move synchronously, so that the rotating elastic warning belt moves along the outer surface of the warning light, and then the warning light flashes to give a warning. With this structural design, the overall warning effect of the warning light is improved, and the problem that the warning light with a fixed color is not easy for people to quickly notice during lighting warning is solved.

[0004] However, in use, it has the following defects:

[0005] Although an elastic warning belt is set to make the warning light flash to improve the warning effect, the warning light is only fixedly installed on one side of the pipeline, and the viewing angle is limited. Coupled with the support structure outside the warning light, it may block the light, thereby affecting the transmission of information and the judgment of the staff, and reducing the warning effect. Utility Model Content

[0006] The purpose of this application is to provide a safety early warning device for long-distance natural gas pipelines, which solves the problem that the warning light in the background art is only fixedly installed on one side of the pipeline, the viewing angle is limited, and the support structure outside the warning light may block the light, thereby affecting the transmission of information.

[0007] To achieve the above object, the present application provides the following technical solution: A safety warning device for a long-distance natural gas pipeline, including a pipeline main body, an annular plate and a fixing frame. The outer side wall of the annular plate is fixedly connected with a T-shaped ring rail. The surface of the T-shaped ring rail is slidably connected with a slider, and the top of the slider is fixedly connected with a warning light. The edge of the surface of the slider on one side of the warning light is fixedly connected with a side plate. The surface of the side plate facing away from the slider is rotatably connected with a driving gear, and a ring gear is provided at the edge of the surface of the annular plate on one side of the driving gear. The driving gear meshes with the ring gear; One end of the fixing frame is fixedly connected to the side wall of the annular plate, and a turntable is rotatably connected to the surface of the fixing frame facing the T-shaped ring rail. A cleaning brush is fixedly connected to the surface of the turntable facing the T-shaped ring rail.

[0008] In this technical solution, after the driving gear rotates, the slider will slide on the T-shaped ring rail. With the flashing warning of the warning light, the light can be seen in all directions, avoiding the limitation of the observation direction and the occlusion of dead angles, ensuring that information can be transmitted normally, and improving the warning efficiency of the device; After the warning light is used for a long time, the light may become weak due to the accumulation of dirt and dust. When the slider rotates to the lower part of the fixing frame, the cleaning brush will clean the surface of the passing warning light during the rotation of the turntable, sweeping away the dirt and dust, and ensuring the normal light brightness of the warning light and the normal transmission of information.

[0009] Preferably, the annular plate is composed of two semi-rings, and a plurality of mounting blocks are uniformly fixedly connected to the left and right side walls of the annular plate in a circumferential array.

[0010] Preferably, a first servo motor is fixedly connected to the surface of the side plate on the opposite side of the driving gear, and the tail end of the transmission shaft of the first servo motor is fixedly connected to the driving gear.

[0011] Preferably, a second servo motor is fixedly connected to the outer surface of the fixing frame on the opposite side of the turntable, and the tail end of the transmission shaft of the second servo motor is fixedly connected to the turntable.

[0012] Preferably, a fan is fixedly connected to the side wall of the fixing frame on one side of the turntable.

[0013] Preferably, a storage battery is fixedly connected to the top of the slider on one side of the warning light.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. Through the T-shaped ring rail, slider, ring gear, driving gear and warning light, the present application can give warnings in all directions. After the driving gear rotates, the slider will slide on the T-shaped ring rail. With the flashing warning of the warning light, the light can be seen in all directions, avoiding the limitation of the observation direction and the occlusion of dead angles, ensuring that information can be transmitted normally, and improving the warning efficiency of the device.

[0016] 2. Through the fixing frame, turntable and cleaning brush, this application can clean the warning light. After the warning light is used for a long time, the light may become weak due to the accumulation of dirt and dust. When the slider rotates under the fixing frame, during the rotation of the turntable, the cleaning brush will clean the surface of the passing warning light, sweeping away the dirt and dust to ensure the normal light brightness of the warning light and the normal transmission of information.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following will be further described in conjunction with specific embodiments.

[0024] A natural gas long-distance pipeline safety warning device, see Figures 1 to 4, including a pipe body 1, an annular plate 2 and a fixing frame 10. A T-shaped ring rail 3 is fixedly connected to the outer side wall of the annular plate 2. A slider 4 is slidably connected to the surface of the T-shaped ring rail 3. The top of the slider 4 is fixedly connected with a warning light 5. The edge of the surface of the slider 4 on one side of the warning light 5 is fixedly connected with a side plate 6. A driving gear 8 is rotatably connected to the surface of the side plate 6 facing away from the slider 4. A ring gear 202 is provided at the edge of the surface of the annular plate 2 on one side of the driving gear 8. The driving gear 8 meshes with the ring gear 202. The slider 4 slides on the T-shaped ring rail 3. With the flashing warning of the warning light 5, the light can be seen in all directions, avoiding the limitation of the viewing direction and the occlusion of dead corners, and ensuring the normal transmission of information. One end of the fixing frame 10 is fixedly connected to the side wall of the annular plate 2. A turntable 13 is rotatably connected to the surface of the fixing frame 10 facing the T-shaped ring rail 3. A cleaning brush 14 is fixedly connected to the surface of the turntable 13 facing the T-shaped ring rail 3. When the slider 4 rotates to the lower part of the fixing frame 10, the cleaning brush 14 will clean the surface of the passing warning light 5 during the rotation of the turntable 13, ensuring the normal light brightness of the warning light 5 and the normal transmission of information.

[0025] Specifically, as Figure 2 and Figure 3 shown, the annular plate 2 is composed of two semi-rings, which is convenient for installation. A number of mounting blocks 201 are evenly fixedly connected to the left and right side walls of the annular plate 2 in a circumferential array. Each mounting block 201 is provided with a bolt hole, which is convenient for screwing in bolts to fix the annular plate 2.

[0026] It should be noted that, as Figure 4 shown, a first servo motor 7 is fixedly connected to the surface of the side plate 6 on the opposite side of the driving gear 8. The tail end of the transmission shaft of the first servo motor 7 is fixedly connected to the driving gear 8. After the first servo motor 7 is started, it will drive the driving gear 8 to rotate, so that the slider 4 slides along the T-shaped ring rail 3, making the warning light 5 perform a circular warning.

[0027] It should be noted that, as Figure 2 shown, a second servo motor 12 is fixedly connected to the outer surface of the fixing frame 10 on the opposite side of the turntable 13. The tail end of the transmission shaft of the second servo motor 12 is fixedly connected to the turntable 13. After the second servo motor 12 is started, it will drive the turntable 13 to rotate, so that the cleaning brush 14 can rotate to clean the surface of the passing warning light 5 and ensure the light brightness.

[0028] It should be noted that, as Figure 2 shown, a fan 11 is fixedly connected to the side wall of the fixing frame 10 on one side of the turntable 13.

After tightening the bolts, the annular plate 2 is connected to the pipeline main body 1. At this time, through the T-shaped ring rail 3, the slider 4, the ring gear 202, the driving gear 8, and the warning light 5, warnings can be given in all directions. After the driving gear 8 rotates, it will cause the slider 4 to slide on the T-shaped ring rail 3. Combined with the flashing warning of the warning light 5, the light can be seen in all directions, avoiding the limitation of the observation direction and the occlusion of dead corners, ensuring that information can be transmitted normally, improving the early warning efficiency of the device. At the same time, through the fixing frame 10, the turntable 13, and the cleaning brush 14, the warning light 5 can be cleaned. After the warning light 5 is used for a long time, the light may become weak due to the accumulation of dirt and dust. When the slider 4 rotates to the lower part of the fixing frame 10, during the rotation of the turntable 13, the cleaning brush 14 will clean the surface of the passing warning light 5, sweeping away the dirt and dust, and ensuring the normal light brightness of the warning light 5 and the normal transmission of information.
