Technical Field

[0001] The utility model relates to the field of gas transportation, in particular to a gas transportation device with a gas leakage prevention function. Background Art

[0002] Gas transportation mainly involves the transportation process of natural gas, liquefied petroleum gas and manufactured coal gas. Among them, natural gas transportation technologies include gas pipelines, gas storage and transportation ships, flexible transmission pipelines, liquefied natural gas tankers and other methods. Among them, gas pipelines are the most common and widespread method, accounting for about 70% of global natural gas transportation. Gas pipelines are divided into long-distance pipelines and trunk pipelines. Long-distance pipelines cover a large area and cross many places at home and abroad, while trunk pipelines are mainly used for natural gas transportation in small and medium-sized areas.

[0003] The current gas transmission device, after long-term use, causes the gas pipeline to need regular maintenance and repair. The disassembly and assembly process is relatively cumbersome, and improper operation will cause interface leakage, which not only causes certain economic losses, but also requires disassembly and assembly again, which greatly affects the work progress. Utility Model Content

[0005] To achieve the above objectives, the utility model provides the following technical solutions: a gas delivery device with anti-leakage function, comprising: a fixing seat, a switching part arranged inside the fixing seat; and a protective part arranged on the top of the fixing seat.

[0006] Preferably, the switching part includes: a rotating roller, which is rotatably connected to the inner wall of the fixed seat through a bearing seat; and a braking gear, which is rotatably connected to the outer wall of the fixed seat through the bearing seat.

[0007] Preferably, one end of the rotating roller passes through one side of the fixing seat and is fixedly connected with a transmission gear, and the outer wall of the rotating roller is clamped and connected with a transmission pipe.

[0008] Preferably, the brake gear is meshingly connected with the transmission gear, and a rotating handle is fixedly connected to one side of the brake gear.

[0009] Preferably, the protection part includes: a connecting pipe fixedly connected to the top of the fixing seat; and a feeding pipe communicatively connected to one end of the connecting pipe.

[0010] Preferably, an electric swivel is fixedly connected to one side of the connecting tube, a connecting groove is provided inside the connecting tube, a sliding groove is provided inside the connecting groove, and a connecting seat is fixedly connected to the outer wall of the connecting tube.

[0011] Preferably, a brake rod is fixedly connected to the outer wall of the electric swivel and is equidistantly arranged around the circumference; a protective sleeve is slidably connected to the inside of the connecting groove; a pull button is fixedly connected to the outer wall of the protective sleeve, and the pull button is adapted to the sliding groove; a connecting plate is rotatably connected between the inner sides of the connecting seat via an axial rod, and one end of the connecting plate is rotatably connected to a clamping plate via an axial rod.

[0012] Preferably, one end of the connecting plate is rotatably connected to a brake clamp via an axle rod, the brake clamp is slidably connected to one side of the connecting pipe, one end of the brake clamp is fixedly connected to a brake ring, and the brake ring is adapted to the brake rod.

[0013] The utility model provides a gas delivery device with a gas leakage prevention function. It has the following beneficial effects:

[0014] (1) The utility model drives the rotating handle through the switching position, so that the rotating handle controls the rotation of the brake gear, thereby rotating the brake gear one circle, achieving the effect of rotating the transmission gear 90 degrees, thereby achieving the effect of switching the transmission tube every 90 degrees. When the internal dimensions of each transmission tube are different, the effect of rapid switching and transmission is achieved. When the internal dimensions of each transmission tube are the same, the effect of rapid replacement is achieved when the transmission tube is damaged.

[0015] (2) The utility model drives the electric swivel to rotate when the transmission tube needs to be replaced through the protective part, thereby driving the brake rod to rotate. Since the movement trajectory of the brake rod gradually changes, the brake ring is used to control the position change of the brake clamp on one side of the connecting tube. When the brake clamps are pulled closer to the center of the center line of the connecting tube, the connecting plate is rotated around the axis, so that the clamping plate no longer fixes the transmission tube. However, according to the continuous rotation of the brake rod, the connecting plate is flipped nearly ninety degrees, so that the clamping plate does not block it when the switching part is replaced. Then, the pull button is pulled and slides upward along the sliding trajectory, so that the protective sleeve is retracted into the connecting groove, which is convenient for replacing the transmission tube and at the same time achieves the effect of reinforcing the gap between the connecting tube and the transmission tube.

[0025] Example 1

[0026] A preferred embodiment of a gas delivery device with a gas leakage prevention function provided by the utility model is as follows Figure 1-4 As shown: a gas delivery device with a gas leakage prevention function, comprising: a fixing seat 1, a switching part 2 arranged inside the fixing seat 1; and a protection part 3 arranged on the top of the fixing seat 1.

[0027] The switching part 2 includes: a rotating roller 211, which is rotatably connected to the inner wall of the fixing seat 1 through a bearing seat; and a braking gear 213, which is rotatably connected to the outer wall of the fixing seat 1 through a bearing seat.

[0028] One end of the rotating roller 211 passes through one side of the fixing base 1 and is fixedly connected to a transmission gear 212 , and the outer wall of the rotating roller 211 is engaged with a transmission tube 215 .

[0029] The brake gear 213 is meshed with the transmission gear 212 , and a rotating handle 214 is fixedly connected to one side of the brake gear 213 .

[0030] Furthermore, this embodiment drives the rotating handle 214 so that the rotating handle 214 controls the braking gear 213 to rotate, thereby rotating the braking gear 213 one circle, thereby achieving the effect of rotating the transmission gear 212 ninety degrees, thereby achieving the effect of switching the transmission tube 215 every ninety degrees. When the internal dimensions of each transmission tube 215 are different, the effect of rapid switching and transmission is achieved. When the internal dimensions of each transmission tube 215 are the same, the effect of rapid replacement when the transmission tube 215 is damaged is achieved.

[0031] Example 2

[0032] Based on Example 1, a preferred embodiment of a gas delivery device with a gas leakage prevention function provided by the utility model is as follows: Figure 1-4 As shown: the protection part 3 includes: a connecting pipe 311, which is fixedly connected to the top of the fixing base 1; and a feeding pipe 312, which is connected to one end of the connecting pipe 311.

[0033] An electric swivel 313 is fixedly connected to one side of the connecting tube 311 . A connecting groove is provided inside the connecting tube 311 . A sliding groove is provided inside the connecting groove. A connecting seat 317 is fixedly connected to the outer wall of the connecting tube 311 .

[0034] The outer wall of the electric swivel 313 is fixedly connected to the brake rod 314, and is equidistantly arranged around the circumference. The inside of the connecting groove is slidably connected to the protective sleeve 315. The outer wall of the protective sleeve 315 is fixedly connected to the pull button 316, which is adapted to the slide groove. The inner side of the connecting seat 317 is rotatably connected to a connecting plate 318 via an axial rod, and one end of the connecting plate 318 is rotatably connected to a clamping plate 319 via an axial rod.

[0035] One end of the connecting plate 318 is rotatably connected to a brake clamp 320 via a shaft. The brake clamp 320 is slidably connected to one side of the connecting pipe 311 . One end of the brake clamp 320 is fixedly connected to a brake ring 321 . The brake ring 321 is adapted to the brake rod 314 .

[0036] Furthermore, in this embodiment, when the transmission tube 215 needs to be replaced, the electric swivel 313 is driven to rotate the electric swivel 313, thereby driving the brake rod 314 to rotate. Since the movement trajectory of the brake rod 314 gradually changes, the brake ring 321 is used to control the position change of the brake clamp 320 on one side of the connecting tube 311. When the brake clamp 320 is pulled closer to the center of the center line of the connecting tube 311, the connecting plate 318 is rotated around the axis, so that the clamping plate 319 no longer fixes the transmission tube 215. However, according to the continuous rotation of the brake rod 314, the connecting plate 318 is flipped nearly ninety degrees, so that the clamping plate 319 does not block it when the switching part 2 is replaced. Then, the pull button 316 is pulled and slides upward along the sliding trajectory to shrink the protective sleeve 315 into the connecting groove, which is convenient for replacing the transmission tube 215 and at the same time achieves the effect of reinforcing the gap between the connecting tube 311 and the transmission tube 215.

[0037] When in use, first, the handle 214 is driven to rotate, so that the handle 214 controls the brake gear 213 to rotate, thereby rotating the brake gear 213 for one circle, so as to achieve the effect of rotating the transmission gear 212 by 90 degrees, thereby achieving the effect of switching the transmission tube 215 every 90 degrees. When the internal dimensions of each transmission tube 215 are different, the effect of fast switching and transmission is achieved. When the internal dimensions of each transmission tube 215 are the same, the effect of fast replacement is achieved when the transmission tube 215 is damaged. Secondly, when the transmission tube 215 needs to be replaced, the electric swivel 313 is driven to rotate the electric swivel 313, thereby driving the brake rod 314 to rotate. Since the movement trajectory of the brake rod 314 gradually changes, the brake rod 314 is driven to rotate. The movable ring 321 controls the position change of the brake clamp 320 on one side of the connecting tube 311. When the brake clamp 320 is pulled closer to the center of the connecting tube 311, the connecting plate 318 rotates around the axis, so that the clamping plate 319 no longer fixes the transmission tube 215. However, according to the continuous rotation of the brake rod 314, the connecting plate 318 is flipped nearly ninety degrees, so that the clamping plate 319 does not block it when the switching position 2 is replaced. Then, the pull button 316 is pulled and slides upward along the sliding trajectory to shrink the protective sleeve 315 into the connecting groove, which is convenient for replacing the transmission tube 215 and at the same time achieves the effect of reinforcing the gap between the connecting tube 311 and the transmission tube 215.
