[0002] De-icing is the process of removing snow, ice or frost from a surface, anti-icing is the application of chemicals that remain on the surface and last for a certain period of time, delaying the reformation of ice, or preventing ice from adhering so that it can be more easily removed mechanically, de-icing can be done mechanically, by applying heat, by using dry or liquid chemicals designed to lower the freezing point of water, or by a combination of these various techniques.

[0003] The de-icing devices currently in use generate relatively large noise during the de-icing process. Therefore, in order to reduce noise pollution, a silencer nozzle is added in front of the pipe of the de-icing device. However, the installation structure of the existing silencer nozzle is relatively complicated, which makes the installation more cumbersome. Therefore, a de-icing pipe silencer nozzle that is easy to install is provided. Utility Model Content

[0017] 1.

[0018] 2. This solution sets a sealing component, which drives the lifting rack to descend when the lifting ring descends, so that the threaded rod rotates under the action of the transmission gear, causing the piston plate to move in the piston cylinder, squeezing the gas in the piston cylinder into the expansion airbag. After the expansion airbag expands, it fills the gap between the deicing pipe and the silencer nozzle. On the one hand, it can further improve the fixation of the silencer nozzle and the deicing pipe, and on the other hand, it can avoid gas circulation at the joint, thereby reducing the spray force of the silencer nozzle.

[0024] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and do not limit the protection scope of the utility model.

[0026] The positioning assembly 5 includes a lifting ring 51 and a limiting rod 57. A telescopic spring 52 is fixedly installed on the lower surface of the lifting ring 51. One end of the telescopic spring 52 is fixedly connected to the inner wall of the bottom surface of the fixed ring 2. A connecting block 53 is fixedly installed on the side wall of the lifting ring 51. One end of the connecting block 53 extends to the inner ring of the fixed ring 2 and is fixedly installed with a driving ring 54. A slot is provided on the outer surface of the lifting ring 51. A spring rod 56 is fixedly installed on the inner wall of the slot. One end of the spring rod 56 is adapted to the size of the positioning hole 3. A positioning pin 55 is fixedly installed on the upper surface of the lifting ring 51.

[0027] In actual application, one end of the deicing pipe is inserted between the silencer nozzle 1 and the fixed ring 2. As the deicing pipe continues to move, the driving ring 54 will move below the fixed ring 2. At this time, the driving ring 54 drives the lifting ring 51 to move downward through the connecting block 53. During the descent, the lifting ring 51 will drive the positioning pin 55 to move out of the through hole in the positioning block 510.

[0028] Embodiment 2: A de-icing pipeline silencer nozzle that is easy to install, which is different from Embodiments 1 and 3 in that Figure 2 As shown, one end of the limit rod 57 is fixedly connected to the inner wall of the fixing ring 2, and a positioning rod 59 is slidably installed on the outer surface of the limit rod 57. A connecting spring 58 is fixedly installed on one end of the positioning rod 59. One end of the connecting spring 58 is fixedly connected to the inner wall of the fixing ring 2, and the other end of the positioning rod 59 extends to the inner ring of the fixing ring 2. A positioning block 510 is fixedly installed on the outer surface of the positioning rod 59, and a through hole is provided on the inner wall of the positioning block 510, and the through hole is adapted to the size of the positioning pin 55.

[0029] In actual application, when the positioning block 510 loses the limit of the positioning pin 55, the positioning rod 59 will move to the outside of the fixing ring 2 on the limiting rod 57 under the action of the connecting spring 58. At this time, the positioning rod 59 fixes the deicing pipe and the silencer nozzle 1 under the action of the connecting spring 58, and a socket matching the size of the positioning rod is provided on the deicing pipe.

[0030] Embodiment 3: A deicing pipeline silencer nozzle that is easy to install, which is different from Embodiment 1 in that Figure 1-2 As shown, the sealing assembly 4 includes a piston cylinder 41, the lower surface of the piston cylinder 41 is fixedly connected to the upper surface of the partition 6, a piston plate 42 is slidably mounted on the inner wall of the piston cylinder 41, a threaded cylinder 43 is fixedly mounted on the side wall of the piston plate 42, one end of the threaded cylinder 43 extends to the outside of the side wall of the piston cylinder 41, a threaded rod 45 is threadedly mounted on the inner wall of the threaded cylinder 43, a transmission gear 46 is fixedly mounted on the outer surface of the threaded rod 45, a lifting rack 47 is fixedly mounted on the upper surface of the lifting ring 51, the lifting rack 47 is meshingly connected to the transmission gear 46, a connecting pipe is connected and installed on the other side wall of the piston cylinder 41, one end of the connecting pipe is connected and installed with an expansion airbag 44, the expansion airbag 44 is made of high temperature resistant material, and an open groove is provided on the inner ring wall of the fixed ring 2.

[0031] In actual application, when the lifting ring 51 descends, the lifting rack 47 will also be driven to descend. As the lifting rack 47 descends, the transmission gear 46 will drive the threaded rod 45 to rotate on the inner wall of the fixed ring 2. At this time, the threaded rod 45 will drive the piston plate 42 to move in the piston cylinder 41 through the threaded cylinder 43 on the outer surface during rotation, and the gas in the piston cylinder 41 will be squeezed into the expansion airbag 44 through the connecting pipe. As the gas in the expansion airbag 44 increases, it will expand from the open groove on the fixed ring 2 to fill and seal the gap between the fixed ring 2 and the deicing pipe.

[0032] Working principle: insert one end of the deicing pipe between the silencer nozzle 1 and the fixing ring 2. As the deicing pipe continues to move, the driving ring 54 will move below the fixing ring 2. At this time, the driving ring 54 drives the lifting ring 51 to move downward through the connecting block 53. During the descent, the lifting ring 51 drives the positioning pin 55 to move out of the through hole in the positioning block 510. At this time, after the positioning block 510 loses the limit of the positioning pin 55, the positioning rod 59 will move to the outside of the fixing ring 2 on the limiting rod 57 under the action of the connecting spring 58. At this time, the positioning rod 59 is inserted into the deicing pipe under the action of the connecting spring 58. The deicing pipe and the silencer nozzle 1 are fixed in the hole. When the lifting ring 51 descends, the lifting rack 47 will also be driven to descend. As the lifting rack 47 descends, the transmission gear 46 will drive the threaded rod 45 to rotate on the inner wall of the fixing ring 2. At this time, the threaded rod 45 will drive the piston plate 42 to move in the piston cylinder 41 through the threaded cylinder 43 on the outer surface during rotation, and the gas in the piston cylinder 41 will be squeezed into the expansion airbag 44 through the connecting pipe. As the gas in the expansion airbag 44 increases, it will expand from the open groove on the fixing ring 2 to fill and seal the gap between the fixing ring 2 and the deicing pipe.

[0033] This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
