Technical Field

[0001] The utility model relates to the technical field of dust-proof spray, in particular to a dust-proof spray device for a high-speed toll station. Background Art

[0002] With the increase in the number of private cars in China, the traffic volume on highways has also gradually increased. As the entrance and exit of highways, toll stations will inevitably bring a lot of dust when passing vehicles. The density and height of dust in the air also change with the traffic volume. It is necessary to use dust-proof spray devices to reduce the dust concentration in the air. The dust-proof spray devices of some highway toll stations have water supply pipes fixed to both sides of the vehicle aisle of the highway toll station through a frame. Multiple atomizing nozzles are installed inside the water supply pipes. When in use, water pressure is used to make water spray out through the atomizing nozzles, thereby processing the dust in the highway toll station. However, the atomizing nozzles are fixedly connected to the water supply pipes. The atomizing nozzles are limited by water pressure and their own spray coverage is limited. The dust prevention treatment range of the vehicle aisles of the highway toll stations is limited and needs to be improved. Utility Model Content

Through the transmission element and with the help of the water flow pressure, the atomization part can be alternately flipped in positive and negative directions around the axis of the water supply pipe, thereby increasing the dust-proof spray range of the device for the lanes of the highway toll station and effectively suppressing the dust from being raised. At the same time, the atomizing nozzle of the device is fixed by an elastic clamp, which is convenient for later replacement.

[0014] 1.

[0021] See also Figure 1-3 ,This embodiment provides a technical solution: a dust-proof spray device for a high-speed toll station, comprising a water supply pipe 1 and an up-and-down swing mechanism 4;

[0022] Water supply pipe 1: Its outer side is rotatably connected with evenly distributed rotating tubes 3 through sealed bearings. The outer right end of the rotating tube 3 is respectively provided with annular grooves 6, plug-in grooves 7 and card grooves 8. The plug-in grooves 7 and card grooves 8 are connected with adjacent annular grooves 6. The inside of the card grooves 8 is card-connected with card seats 9. Atomizing nozzles 10 are provided between two adjacent card seats 9. The outer side of the water supply pipe 1 is provided with evenly distributed mounting seats 2. The outer right end of the rotating tube 3 is provided with annular seats 11. The right side of the annular seats 11 is provided with extrusion seats 14 through evenly distributed telescopic columns 12 and springs 13. The springs 13 are movably connected with the outer ends of adjacent telescopic columns 12. The right side of the extrusion seats 14 is provided with rubber sealing rings 15. First, the device is fixed to the designated positions on both sides of the lanes of the expressway toll station through the mounting seats 2, and then the water supply pipe 1 is connected to the external high-pressure water supply pipeline through the flange. When the expressway toll station is sprayed with dust, the high-pressure water flows through the external high-pressure water supply pipe and the supply pipe. The water pipe 1 is sprayed out through the atomizing nozzle 10, so as to deal with the dust and the like caused by the driving of the car. When replacing the atomizing nozzle 10 of the expressway toll station, the atomizing nozzle 10 is pressed to make the internal card seat 9 move left along the card slot 8 to the annular groove 6, and then the atomizing nozzle 10 is reversed 90 degrees along the annular groove 6 through the card seat 9 to align with the plug-in groove 7, and then the atomizing nozzle 10 is slid out along the plug-in groove 7 and replaced. The replaced atomizing nozzle 10 is installed according to the same principle. The installed atomizing nozzle 10 is pressed against the card slot 8 by the compression elastic force of the spring 13 so that the extrusion seat 14 prevents the two from moving relative to each other, and the contact gap between the atomizing nozzle 10 and the rotating tube 3 is reduced by the rubber sealing ring 15. The atomizing nozzle 10 on the dust-proof spray device in the expressway toll station is easy to replace. The dust-proof spray device of the expressway toll station, the atomizing nozzle 10 is fixed by elastic card connection, and the later replacement operation is convenient;

[0023] The up-down swing mechanism 4 is arranged between the rotating pipe 3 and the water supply pipe 1. The up-down swing mechanism 4 includes a fixed seat 41, a rotating shaft 1 42, a rotating shaft 2 43, a gear 1 44, a half gear 45, a connecting seat 46 and an inner gear ring 47. The fixed seat 41 is evenly arranged inside the water supply pipe 1. The front side of the fixed seat 41 is rotatably connected with the rotating shaft 1 42 and the evenly distributed rotating shaft 2 43 through a bearing. The front end of the rotating shaft 1 42 and the rear end of the rotating shaft 2 43 are both provided with a gear 1 44. The two adjacent gears 1 44 are meshed and connected. The front end of the rotating shaft 2 43 is provided with a half gear 45. The inner part of the rotating tube 3 is provided with an inner gear ring 47 through a connecting seat 46, and the half gear 45 is installed in cooperation with the adjacent inner gear ring 47. The up and down swing mechanism 4 also includes a driving blade 48, and the driving blade 48 is arranged at the rear end of the rotating shaft 42. The inner wall of the water supply pipe 1 is provided with evenly distributed avoidance grooves 5, and the avoidance grooves 5 are installed in cooperation with the adjacent connecting seat 46. When the high-pressure water flow flows in the water supply pipe 1, the driving blade 48 drives the rotating shaft 41 to rotate through the contact pressure of the water body. The rotating shaft 41 is connected to the meshing between the gears 44. The two adjacent rotating shafts 43 are connected so that they rotate forward and reverse respectively. The forward rotating shaft 43 drives the half gear 45 on the right side to rotate. The half gear 45 on the right side is meshed and connected so that the inner gear ring 47 indirectly drives the atomizing nozzle 10 to turn forward around the axis of the water supply pipe 1. When the half gear 45 on the right side is not meshed with the inner gear ring 47, the half gear 45 on the left side starts to mesh and connect with the inner gear ring 47, so that the inner gear ring 47 indirectly drives the atomizing nozzle 10 to reversely turn around the axis of the water supply pipe 1 and reset. The body flow causes the atomizing nozzle 10 to rotate alternately forward and reverse around the axis of the water supply pipe 1, thereby increasing the atomization range of the atomizing nozzle 10, thereby improving the dust prevention effect of the device on the highway toll station, and it is easy to use. During this process, the connecting seat 46 moves adaptively along the avoidance groove 5 to avoid jamming. The dust prevention spray device of the highway toll station uses transmission elements and the water flow pressure to enable the atomizing part to flip alternately forward and reverse around the axis of the water supply pipe 1, thereby improving the dust prevention spray range of the device on the lanes of the highway toll station and effectively suppressing dust from being raised.

[0024] The working principle of the dust-proof spray device for a highway toll station provided by the utility model is as follows: first, the device is fixed to the designated positions on both sides of the lane of the highway toll station through the mounting seat 2, and then the water supply pipe 1 is connected to the external high-pressure water supply pipe through the flange. When the dust-proof spray is performed on the highway toll station, the high-pressure water flow is sprayed through the external high-pressure water supply pipe and the water supply pipe 1 through the atomizing nozzle 10, so as to deal with the dust and the like driven by the driving process of the car. When the high-pressure water flow flows in the water supply pipe 1, the contact pressure of the water body causes the driving blade 48 to drive the rotating shaft The rotating shaft 1 41 rotates, and the rotating shaft 1 41 is meshedly connected with the gear 1 44, so that the two adjacent rotating shafts 2 43 rotate forward and reverse respectively. The forward rotating shaft 2 43 drives the half gear 45 on the right side to rotate. The half gear 45 on the right side is meshedly connected, so that the inner gear ring 47 indirectly drives the atomizing nozzle 10 to turn forward around the axis of the water supply pipe 1. When the half gear 45 on the right side is not meshed with the inner gear ring 47, the half gear 45 on the left side begins to mesh with the inner gear ring 47, so that the inner gear ring 47 indirectly drives the atomizing nozzle 10 to turn forward around the axis of the water supply pipe 1. The nozzle 10 is reversely turned around the axis of the water supply pipe 1 and reset. The water flow is used by the transmission element to make the atomizing nozzle 10 rotate alternately forward and reverse around the axis of the water supply pipe 1. By increasing the atomization range of the atomizing nozzle 10, the dust prevention effect of the device on the high-speed toll station is improved, and it is easy to use. During this process, the connecting seat 46 moves adaptively along the avoidance groove 5 to avoid jamming. When replacing the atomizing nozzle 10 of the high-speed toll station, press the atomizing nozzle 10 to move the internal card seat 9 along the card groove 8 to the left into the annular groove 6. Then, the atomizing nozzle 10 is reversed 90 degrees along the annular groove 6 through the card seat 9 to align with the plug-in groove 7, and then the atomizing nozzle 10 is slid along the plug-in groove 7 to be taken out and replaced. The replaced atomizing nozzle 10 is installed according to the same principle. The installed atomizing nozzle 10 is pressed tightly against the card slot 8 by the compression elastic force of the spring 13 so that the extrusion seat 14 prevents the two from moving relative to each other. The contact gap between the atomizing nozzle 10 and the rotating tube 3 is reduced by the rubber sealing ring 15. The atomizing nozzle 10 on the dust-proof spray device in the high-speed toll station is easy to replace.
