However, because there is a gap between each train skin of the train skin, the conventional valve body has a certain delay in controlling the spraying device to close and operate. When the gap between the train skins is located under the spraying device, the spraying device cannot be closed in time, which will cause the leakage of excess dust suppressant, directly falling on the track from the gap, causing the waste of dust suppressant and the like resources, and especially in winter, the liquid such as dust suppressant falling on the track is easy to freeze, which is not conducive to the transportation vehicle to continue driving on the track, and has certain safety hazards.

[0036] The utility model discloses a prevent leaking liquid spray device 100, by adopting set up swing arm 2 on stand 1, with swing arm 2 is supported at a certain height, and spray mechanism 3 is arranged at one end of swing arm 2, the train skin is convenient to pass through under spray mechanism 3, when the train skin passes, sleeve 32 is rotated by drive mechanism 4, sleeve 32 rotates and opens valve 35, and makes the position of nozzle 321 correspond with spray head 33, so that the nozzle passes through nozzle 321 in time and sprays the train skin under spray mechanism 3, when the empty block between train skin drives to the under spray mechanism 3, sleeve 32 is rotated by drive mechanism 4, when sleeve 32 rotates, the position of nozzle 321 and spray head 33 is quickly staggered, and sleeve 32 rotates and closes valve 35 simultaneously, and the excess liquid that the spray head 33 sprays is blocked in sleeve 32 due to the delay of valve 35 closing, thereby preventing liquid to flow to the empty block between train skin and the track below, after the next train skin arrives, sleeve 32 rotates again, so that the liquid in it sprays on the train skin, which reduces the waste of spray liquid to a certain extent, saves the cost, and effectively solves the problem of safety hazard caused by liquid falling on the track.

[0037] Among them, the spray liquid in spray pipe 31 is transported by the pipeline in swing arm 2.

[0038] In an embodiment, the valve stem of each valve 35 is connected with a bevel gear 351, the inner wall of the sleeve 32 is provided with a ring gear 322 corresponding to the position of the bevel gear 351, the inner ring of the ring gear 322 is engaged with the corresponding bevel gear 351, and the driving mechanism is used to drive the sleeve 32 to rotate around the spray pipe 31, so that each ring gear 322 can drive the bevel gear 351 engaged therewith to rotate, thereby driving the corresponding valve stem to rotate to open or close the valve 35.

[0039] It can be understood that the engagement transmission design of the bevel gear 351 and the ring gear 322 enables the sleeve 32 to directly drive the valve stem to rotate when the sleeve 32 rotates, thereby achieving rapid opening or closing of the valve 35. Each ring gear 322 is arranged on the sleeve 32, and the spray nozzle 321 moves away from the spray head 33 and the valve 35 is closed synchronously when the sleeve 32 rotates, which ensures that the spray liquid can be prevented from continuing to fall on the track in time. The gear transmission mode has simple and reliable structure and high stability.

[0040] In an embodiment, the driving mechanism 4 includes a driving motor 41, a driving gear 42, and a driven gear 43 engaged with the driving gear 42. The driving gear 42 is connected with the output shaft of the driving motor 41, the driven gear 43 is sleeved on the outer circumferential side of one end of the sleeve 32 close to the swing arm 2, the driving motor 41 is arranged on the top of one end of the swing arm 2 close to the sleeve 32, and the driving motor 41 drives the driven gear 43 to rotate through the driving gear 42, so as to drive the sleeve 32 to rotate through the driven gear 43.

[0041] It can be understood that the driving motor 41 can stably transmit power to the sleeve 32 through the engagement transmission of the driving gear 42 and the driven gear 43, thereby driving the sleeve 32 to rotate. This gear transmission mode has high transmission precision, which ensures that the angle and speed of the sleeve 32 rotating are controllable, thereby achieving precise control of the valve 35.

[0042] It should be noted that the driving motor 41 adopts a stepper motor in the prior art, which can accurately control the number of rotations of the driving gear 42, thereby accurately controlling the opening and closing of the valve 35.

[0043] Moreover, the driving motor 41 is arranged on the top of the swing arm 2, and the swing arm 2 supports the driving motor 41, which can maintain stable operation of the driving motor 41.

[0044] In an embodiment, the driving motor 41 and the driving gear 42 are connected through a shaft coupling, and the driving gear 42 and the driven gear 43 form a speed reduction assembly. Specifically, the number of teeth of the driving gear 42 is less than that of the driven gear 43. By arranging the shaft coupling, the power of the driving motor 41 can be accurately transmitted to the driving gear 42, reducing vibration and deviation in the power transmission process. At the same time, the gear transmission itself has high transmission accuracy, further ensuring that the rotation angle and speed of the sleeve 32 are controllable. The number of teeth of the driving gear is less than that of the driven gear 43, forming a speed reduction transmission structure. The speed reduction transmission can reduce the output rotation speed and increase the output torque, so that the sleeve 32 can obtain greater driving force when rotating, thereby ensuring smooth operation.

This design reduces the volume of the spraying mechanism 3, facilitates installation and maintenance, and further fixes the positions of the valve body and the communication pipe 34, preventing displacement or damage of the valve body and the communication pipe 34 when the valve 35 is opened or closed, and the structure is more stable.

[0047] By exposing the mounting end of the communication pipe 34 outside the mounting groove, the connection between the spray head 33 and the communication pipe 34 is ensured to be convenient and reliable, and the influence of other components on the position of the spray head 33 is avoided.

[0048] In an embodiment, the communication pipe 34 includes a flow guide section 341, a connecting section 342, and a mounting section 343 connected in sequence.

It can be understood that the connecting section 342 and the flow guide section 341 are embedded in the mounting grooves at the bottom of the spray pipe 31, fully utilizing the space inside the spray pipe 31, so that the structure of the entire spraying mechanism 3 is more compact. This design reduces the volume of the device, facilitates installation and maintenance; at the same time, the flow guide section 341, the connecting section 342, and the mounting section 343 are arranged in a Z shape, which is conducive to arranging the valve 35, so that the valve 35 and the spray head 33 are arranged in a horizontal direction and do not interfere with each other.

[0050] By evenly arranging the spray heads 33, the coverage of spraying liquid to the train is ensured to be more uniform, and the spraying efficiency can be significantly improved by simultaneously working of the plurality of spray heads 33, and the uniformly distributed spray heads 33 can cover a larger area and have a better spraying effect.

[0052] It can be understood that by arranging the cross rod 5 at the end of the spray pipe 31 away from the swing arm 2, and connecting the first connecting seat 51 on the cross rod 5 to the second connecting seat 11 on the stand column 1 through the pull rope 6, since the cross rod 5, the spray pipe 31 and the swing arm 2 are sequentially connected, the whole formed by the three has a certain length, and by arranging the pull rope 6, the stability of the three can be better maintained, the non-uniform spraying caused by shaking can be prevented, the burden of the swing arm 2 is reduced, and the reliability is better.
