[0019] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0020] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0021] like Figure 1-6 As shown, a powered hidden multifunctional pipeline reciprocating wiping and cleaning mechanism comprises: a piston cylinder 1, a piston-type pneumatic vibrator 2 mounted inside the piston cylinder 1, mounting mechanisms mounted at both ends of the piston cylinder 1, tubular brushes 3 spaced apart and sleeved on the outside of the piston cylinder 1 and mounted on a pair of mounting mechanisms, and a liquid spraying device mounted on one set of the mounting mechanisms, wherein the liquid spraying device comprises at least one nozzle 4 with the liquid spraying end facing the brush 3.

[0022] In the above technical solution, the piston-type pneumatic vibrator 2 will vibrate after ventilation, and the vibration drives the wiping and cleaning mechanism to move in the gun barrel, driving the gun brush 3 to reciprocate and wipe the inner wall of the gun barrel. At the same time, after the liquid is passed through the liquid spraying device, the liquid will be sprayed out through the nozzle 4, and the liquid will be sprayed toward the gun brush 3. The sprayed liquid cooperates with the gun brush 3 to facilitate cleaning the gun barrel; The piston-type pneumatic vibrator 2 is located inside the piston cylinder 1, which can prevent liquid and some impurities from entering the interior of the piston-type pneumatic vibrator 2 during use. The internal piston-type pneumatic vibrator 2 can increase its service life and protect the piston-type pneumatic vibrator 2; The piston-type pneumatic vibrator 2 is arranged inside the piston cylinder 1, which can reduce the overall length of the wiping and cleaning mechanism and facilitate portability; the wiping and cleaning mechanism can not only clean the gun barrel, but also clean the pipeline; The piston-type pneumatic vibrator 2 is located inside the gun brush 3 and can balance the weight of the gun brush 3. If the piston-type pneumatic vibrator 2 is installed at the end, the end of the gun brush 3 away from the piston-type pneumatic vibrator 2 will be tilted upward under the action of gravity. Therefore, the internal piston-type pneumatic vibrator 2 is conducive to keeping the gun brush 3 balanced and evenly wiping the inner wall of the gun barrel. The type of liquid can be supplied according to actual needs, such as cleaning liquid, rust preventive liquid, degreasing agent or a mixture of them; The piston-type pneumatic vibrator 2 is a prior art, and its structure and working principle are not described in detail herein.

[0023] In a preferred embodiment of the present invention, one set of mounting mechanisms is equipped with an air inlet nozzle 5 connected to the piston-type pneumatic vibrator 2, the mounting mechanism connected to the air inlet nozzle 5 is a rear-end mounting mechanism, and the other set of mounting mechanisms is a front-end mounting mechanism; The rear end mounting mechanism includes a valve seat 6 coaxially and sealedly fixedly connected to one end of the piston cylinder 1 and a rear end cover 21 coaxially assembled on the valve seat 6 , and the air inlet nozzle 5 is assembled on the air inlet end of the valve seat 6 .

[0024] In the above technical solution, the external air supply device is connected to the air inlet nozzle 5, and the gas enters the piston-type pneumatic vibrator 2, driving the piston-type pneumatic vibrator 2 to vibrate.

[0025] In a preferred embodiment of the present invention, the front end mounting mechanism includes a front end fixing seat 7 coaxially and sealedly fixedly connected to the end of the piston cylinder 1 away from the rear end cover 21 and a front end cover 8 coaxially and detachably assembled on the fixing seat by at least one mounting bolt.

[0026] In the above technical solution, when the gun brush 3 needs to be replaced, the mounting bolts are loosened to remove the front end cover 8, and the gun brush 3 can be removed. Then a new gun brush 3 is placed on the outside of the piston cylinder 1, and one end of the gun brush 3 is in contact with the rear end mounting mechanism. Then the front end cover 8 can cooperate with the rear end mounting mechanism to clamp the gun brush 3, making it simple and convenient to replace the gun brush 3.

[0027] In a preferred embodiment of the present invention, a plurality of first exhaust holes 9 are provided through the side wall of the piston cylinder 1, and a second exhaust hole 10 having an axis parallel to the axis of the piston cylinder 1 is provided through the rear end cover 21 and / or the front end cover 8.

[0028] In the above technical solution, the gas entering the piston-type pneumatic vibrator 2 will be discharged, enter between the piston cylinder 1 and the gun brush 3 through the first exhaust hole 9, and then be discharged through the second exhaust hole 10; the gas will be discharged from the rear end cover 21 and / or the front end cover 8, and the direction of the airflow is parallel to the axis of the piston cylinder 1. Therefore, the discharged gas can reduce the volatility of the liquid on the inner wall of the gun barrel, prolong the reaction time of the liquid with copper hanging, gunpowder residue and gas smoke, which is conducive to wiping and cleaning the gun barrel; if the discharge direction of the airflow is facing the inner wall of the gun barrel, it will accelerate the volatilization of the liquid on the inner wall, and the liquid will be blown dry before reacting, which is not conducive to cleaning the inner wall of the gun barrel.

[0029] In a preferred embodiment of the present invention, a mounting flange 11 is protruding from the edges of the front cover 8 and the rear cover 21 and is clamped on the outer side of the end of the brush 3.

[0030] In the above technical solution, the mounting flange 11 can be stuck on the outer side of the end of the blasting brush 3 , so as to play a role in positioning and mounting the blasting brush 3 .

[0031] In a preferred embodiment of the present invention, a tubular portion 12 for mounting the air inlet nozzle 5 is coaxially protruded from one side of the air valve seat 6 away from the piston cylinder 1; The liquid spraying device further comprises a mounting nut 13 coaxially fixedly assembled on the tubular portion 12, a liquid spraying seat 14 coaxially fixedly assembled on the mounting nut 13, and a liquid receiving head 15 assembled on the liquid spraying seat 14; The liquid spray seat 14 is recessed with a first groove 16 for installing the liquid receiving head 15, and the liquid spray seat 14 is recessed with a second groove 17 for installing the corresponding nozzle 4. The liquid spray seat 14 is provided with a liquid passage for connecting the first groove 16 and the second groove 17.

[0032] In the above technical solution, the liquid enters the first groove 16 through the liquid receiving head 15, then enters the second groove 17 through the liquid passage, and is then discharged through the nozzle 4; The gas enters the tubular portion 12 through the air inlet nozzle 5 and then communicates with the piston-type pneumatic vibrator 2 through the tubular portion 12 .

[0033] In a preferred embodiment of the present invention, the drainage channel includes an annular channel 18 arranged on the side wall where the spray seat 14 and the mounting nut 13 are in contact, a first channel 19 connected to the first groove 16 and the annular channel 18, and at least one second channel 20 for connecting the annular channel 18 and the corresponding second groove 17.

[0034] In the above technical solution, the liquid passes through the first channel 19 in the first groove 16 to the annular channel 18, and then enters the corresponding second groove 17 through the second channel 20, and can simultaneously supply liquid to several nozzles 4; When the second channel 20 is processed, a process hole is required, and the process hole will be subsequently blocked with a blocking piece.

[0035] In a preferred embodiment of the present invention, at least two first sealing rings are mounted on the inner wall of the liquid spray seat 14 that contacts the mounting nut 13 , and the annular channel 18 is located between two adjacent first sealing rings.

[0036] In the above technical solution, the first sealing ring can improve the sealing between the liquid spray seat 14 and the mounting nut 13 , thereby preventing liquid from leaking from the gap between the liquid spray seat 14 and the mounting nut 13 .

[0037] In a preferred embodiment of the present invention, at least one second sealing ring is provided between the front end fixing seat 7 and the valve seat 6 and the piston cylinder 1 .

[0038] In the above technical solution, the second sealing ring can improve the sealing performance of both ends of the piston cylinder 1, and prevent liquid from entering the interior of the piston cylinder 1 through the gaps at both ends of the piston cylinder 1; because several first exhaust holes 9 on the piston cylinder 1 are exhausting, even if some liquid enters between the piston cylinder 1 and the gun brush 3, it cannot enter the interior of the mounting cylinder through the first exhaust holes 9 under the action of the airflow.

[0039] In a preferred embodiment of the present invention, a flange portion is protruding from the outer wall of the mounting nut 13 and can contact one side of the spray seat 14. The mounting nut 13 is clamped with a mounting retaining ring that cooperates with the flange portion to fix the spray seat 14.

[0040] In the above technical solution, the mounting retaining ring and the flange portion clamp the liquid spray seat 14 from two directions, which is simple to assemble and easy to operate. When cleaning the liquid passage, the mounting retaining ring is removed, and the liquid spray seat 14 can be removed to expose the liquid passage inside.

[0041] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
