DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention provides Figure 1-7The explosion-proof exhaust pipe pulse cleaning device for an aircraft refueling vehicle shown in the figure comprises a machine housing 1 and a pipeline. An air driving device is further added inside the machine housing 1. A water tank 11 is installed on the machine housing 1. A circulating pump is installed inside the machine housing 1. A water outlet pipe 12 and a water return pipe 13 are installed on one side of the machine housing 1. A corrugated hose 14 is installed at one end of the water outlet pipe 12 and the water return pipe 13. The corrugated hose 14 is connected to the exhaust pipe. The circulating pump can transport the water flow inside the water tank 11 to the water outlet pipe 12 through the pipeline, and then the water outlet pipe 12 is transported to the exhaust pipe through the corrugated hose 14, and then the water flows back to the inside of the water tank 11 through the corrugated hose 14 and the water return pipe 13. The air driving device is composed of an air pump and a solenoid valve, so that gas can be intermittently transported to the inside of the water delivery pipe 12, so that the cleaning liquid discharged from the water outlet pipe 12 forms a pulse cleaning, so that the cleaning liquid circulates to perform pulse cleaning on the exhaust pipe, and a pressure sensor is installed on the pipeline. The machine housing 1 is equipped with a display instrument and a control button to cooperate with the circulation pump.

The inner cavity of the corrugated sleeve 24 is connected to the inner cavity of the water outlet pipe 12, so that when the water flows out through the water outlet pipe 12 under the action of the circulating pump, the water inside the water outlet pipe 12 The flow can also enter the interior of the corrugated sleeve 24, and the water pressure inside the corrugated sleeve 24 is the same as the water pressure inside the outlet pipe 12. The limit assembly 25 is arranged at the top of the corrugated sleeve 24, and the triangular pyramid 27 is installed at the bottom of the connecting pipe 26. The triangular pyramid 27 is located at the top of the corrugated sleeve 24. When the water pressure inside the outlet pipe 12 and the corrugated sleeve 24 increases, the corrugations outside the corrugated sleeve 24 expand, so that the top of the corrugated sleeve 24 lifts the limit assembly 25 until the water pressure inside the outlet pipe 12 and the corrugated sleeve 24 reaches a certain safety value.

The mounting sleeve 23 can also limit the shape of the bellows sleeve 24 to prevent the bellows sleeve 24 from lateral expansion when the water pressure inside the bellows sleeve 24 increases. That is, when the water pressure inside the bellows sleeve 24 increases, the top of the bellows sleeve 24 can be raised, and the mounting block 21, the connecting cap 22 and the mounting sleeve 23 form a linkage with the fixing component 3.

[0042] Furthermore, the bottom of the corrugated sleeve 24 is fixedly connected with a connecting ring 210, and the connecting ring 210 is sleeved and slidably sleeved on the bottom of the inner cavity of the connecting cap 22.

When the corrugated sleeve 24 is punctured to release the pressure on the water outlet pipe 12, the cleaning fluid discharged from the connecting pipe 26 can flow back to the water tank 11 through the rubber hose 29, thereby avoiding waste of cleaning fluid.

The limiting spring 253 is sleeved inside the mounting sleeve 23. The limiting spring 253 is located at the top of the limiting collar 251. The limiting spring 253 can give the limiting collar 251 an elastic extrusion force, so that the limiting collar 251 exerts an extrusion force on the corrugated sleeve 24, thereby When the water pressure inside the corrugated sleeve 24 reaches a safe value, the top of the corrugated sleeve 24 can lift the limiting ring 251 to a certain height, so that the top of the corrugated sleeve 24 contacts the triangular pyramid 27, and the outer wall of the connecting sleeve 252 is slidably sleeved with an adjusting ring 254, and the bottom of the limiting spring 253 is squeezed and fitted with the adjusting ring 254. The outer wall of the connecting sleeve 252 is fixedly connected with a support block 255, and a plurality of support blocks 255 are fixedly connected at equal distances on both sides of the outer wall of the connecting sleeve 252.

The limit spring 253 can give the adjusting collar 254 an elastic force toward the support block 255, so that the adjusting collar 254 and the block 256 on the support block 255 maintain a stable engaged state. When the adjusting collar 254 is disassembled, the adjusting collar 254 is rotated to make the slot 257 on the inner wall of the adjusting collar 254 correspond to the support block 255, so that the adjusting collar 254 can slide outside the connecting sleeve 252, and when the adjusting collar 254 is engaged with the block 256, the top of the adjusting collar 254 is engaged with the bottom of the support block 255 above. The distance between the parts is greater than the height of the block 256, so that the sliding adjustment ring 254 can be raised and separated from the block 256, and the limit spring 253 gives the limit ring 251 an extrusion force toward the corrugated sleeve 24 through the adjustment ring 254 and the connecting sleeve 252, and changes the position of the adjustment ring 254 on the outer wall of the connecting sleeve 252, and the position where the top of the corrugated sleeve 24 contacts the triangular pyramid 27 remains unchanged, so that when the top of the corrugated sleeve 24 contacts the triangular pyramid 27, the compression deformation of the limit spring 253 can be changed, thereby changing the safety value of the water pressure inside the corrugated sleeve 24 when the top of the corrugated sleeve 24 contacts the triangular pyramid 27.

[0044] In particular, the fixing assembly 3 includes a fixing plate 31, a first fixing block 32, a second fixing block 33, a locking plate 34 and a locking assembly 36.
