Detailed Description of the Invention
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to the attached Figure 1 - attached Figure 8 , the embodiment of the present invention provides a natural gas hydrogen blending device, including a housing 1. Anti-leakage mechanisms 2 are provided on both sides of the housing 1. The anti-leakage mechanism 2 is used to prevent gas leakage inside the housing 1. A splicing mechanism 3 is provided outside the anti-leakage mechanism 2. The splicing mechanism 3 is used for quick connection of pipelines. A mixing impeller 4 is rotatably connected inside the housing 1. The mixing impeller 4 can rotate according to the gas flow, so as to conveniently mix the gas. A gas collecting hopper 5 is fixedly connected to one side outside the housing 1.
[0021] The leakage prevention mechanism 2 includes a fixed pipe 201 which provides an installation position. The outer parts of the two fixed pipes 201 are respectively fixedly connected to both sides of the housing 1. An anti-leakage ring 202 is fixedly connected inside the fixed pipe 201. A return spring 203 is fixedly connected to the side of the anti-leakage ring 202 close to the housing 1. The side of the return spring 203 away from the anti-leakage ring 202 is fixedly connected to a sliding frame 204 which can provide an installation position. The return spring 203 can drive the sliding frame 204 to reset by its own elastic force. A connecting rod 205 is fixedly connected to the middle of the sliding frame 204. One end of the connecting rod 205 away from the sliding frame 204 is fixedly connected to a plug 206. The connecting rod 205 can connect the plug 206. The plug 206 can block the inside of the anti-leakage ring 202, so as to prevent gas leakage. A clamping ring 207 is fixedly connected to the outer side of the fixed pipe 201 away from the housing 1. The return spring 203 is arranged inside the fixed pipe 201. The sliding frame 204 is slidably connected inside the fixed pipe 201. A sealing sleeve is sleeved outside the plug 206. The side of the clamping ring 207 away from the housing 1 is a curved surface. A protective sleeve is arranged on the side of the sliding frame 204 away from the plug 206. The connecting rod 205 penetrates through the inside of the anti-leakage ring 202. When mixing gas, first insert the splicing mechanism 3 into the inside of the fixed pipe 201. After the splicing mechanism 3 is inserted into the inside of the fixed pipe 201, it can push the sliding frame 204 in the direction close to the connecting rod 205, so as to push the connecting rod 205 and the plug 206. When the plug 206 moves out of the inside of the connecting rod 205, gas can be passed into the fixed pipe 201 through the splicing mechanism 3. When the splicing mechanism 3 is pulled out of the inside of the fixed pipe 201, under the action of the reaction force of the return spring 203, it can drive the sliding frame 204 to reset, so as to drive the connecting rod 205 and the plug 206 to reset. When the plug 206 enters the inside of the anti-leakage ring 202, the plug 206 can block the anti-leakage ring 202, so as to prevent gas from leaking out.
[0022] The splicing mechanism 3 includes an installation pipe 301 which is a vent pipe. The outer side of the installation pipe 301 close to the housing 1 provides an installation position. A fixing ring 302 is fixedly connected to the outside of the installation pipe 301, and the fixing ring 302 can provide an installation position. A clamping spring 303 is sleeved on the outside of the installation pipe 301. An active ring 304 is slidably connected to the outside of the installation pipe 301, and the active ring 304 can provide an installation position. An installation fixing ring 305 is fixedly connected to the side of the installation pipe 301 far from the fixing ring 302, and the installation fixing ring 305 can provide an installation position. A plurality of clamping arms 306 are rotatably connected to the inside of the installation fixing ring 305. The clamping arms 306 can be clamped with the clamping ring 207 by rotation. A sliding column 307 is fixedly connected to the side of the clamping arm 306 far from the housing 1. A plurality of limiting frames 308 are fixedly connected to the outside of the active ring 304, and the limiting frames 308 can provide a sliding space for the sliding column 307. The sliding column 307 can rotate inside the limiting frame 308 and can also slide inside the limiting frame 308. The sliding column 307 is arranged inside the limiting frame 308. A driving ring 309 is fixedly connected between the outsides of the plurality of limiting frames 308. A resisting pipe 310 is fixedly connected to the inner side of the installation pipe 301 close to the housing 1. One end of the clamping spring 303 is fixedly connected to the side of the fixing ring 302 close to the housing 1, and the other end of the fixing ring 302 is fixedly connected to the side of the active ring 304 far from the housing 1. The resisting pipe 310 is slidably connected to the inside of the fixed pipe 201. A base 7 is fixedly connected to the bottom of the housing 1. An exhaust pipe 6 is fixedly connected to the side of the air-gathering hopper 5 far from the housing 1. A rubber sleeve is sleeved on the outside of the driving ring 309. The side of the clamping arm 306 close to the housing 1 is a curved surface. When the clamping arm 306 is clamped with the clamping ring 207 for pipe connection, first, the resisting pipe 310 is aligned with the inside of the fixed pipe 201 and inserted. At this time, the resisting pipe 310 pushes the connecting rod 205 to move, so that the plug 206 no longer blocks the anti-leakage ring 202. At the same time, since one surface of both the clamping arm 306 and the clamping ring 207 is a curved surface, when the plug 206 is squeezed, the plug 206 will rotate to both sides under the extrusion of the sliding column 307, so that it can move into the vertical surface of the clamping ring 207. After entering the vertical surface, it can push the active ring 304 to move towards the direction close to the housing 1 under the reaction force of the fixing ring 302, so that the tail of the clamping arm 306 can be pushed to rotate the clamping arm 306, and it can be clamped with the clamping ring 207, thus completing the installation of the pipe. When disassembling, only need to pull the driving ring 309 in the opposite direction, which can drive the limiting frame 308 to move away from the housing 1, so that the head of the clamping arm 306 can be pulled up, and then the pipe can be loosened, and the installation pipe 301 can be disassembled.
[0023] Working principle: When mixing gases, first insert the splicing mechanism 3 into the interior of the fixed pipe 201. After the splicing mechanism 3 is inserted into the interior of the fixed pipe 201, it can push the sliding frame 204 in the direction close to the connecting rod 205, thereby pushing the connecting rod 205 and the plug 206. When the plug 206 moves out of the interior of the connecting rod 205, ventilation can be carried out to the fixed pipe 201 through the splicing mechanism 3. When the splicing mechanism 3 is pulled out of the interior of the fixed pipe 201, under the reaction force of the return spring 203, it can drive the sliding frame 204 to reset, thereby driving the connecting rod 205 and the plug 206 to reset. When the plug 206 enters the interior of the anti-leakage ring 202, the plug 206 can block the anti-leakage ring 202, so that gas leakage can be prevented; When connecting pipes, first align the abutting pipe 310 with the interior of the fixed pipe 201 and insert it. At this time, the abutting pipe 310 pushes the connecting rod 205 to move, so that the plug 206 no longer blocks the anti-leakage ring 202. At the same time, since one surface of both the engaging arm 306 and the engaging ring 207 is a curved surface, when the plug 206 is squeezed, the plug 206 will rotate to both sides under the squeezing action of the sliding column 307, so that it can move into the vertical surface of the engaging ring 207. After entering the vertical surface, it can push the movable ring 304 in the direction close to the housing 1 under the reaction force of the fixed ring 302, thereby pushing the tail of the engaging arm 306 so that the engaging arm 306 can rotate and engage with the engaging ring 207, thus completing the installation of the pipe. When disassembling, just pull the driving ring 309 in the opposite direction, which can drive the limiting frame 308 to move away from the housing 1, thereby pulling the head of the engaging arm 306 to tilt up, and then the pipe can be released, so that the installation pipe 301 can be disassembled.
