[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0027] The following reference is attached Figures 1 to 4 Describe the roadway dust flushing vehicle according to an embodiment of the present utility model.

[0028] As Figures 1 to 3 shown, the roadway dust flushing vehicle according to an embodiment of the present utility model includes: a vehicle body 1, a water tank 2, a water gun 3, and a first driving device 4. The water gun 3 includes a connecting wrist 31, a nozzle seat 32, and a plurality of nozzles 33.

[0029] The water tank 2 is installed on the vehicle body 1. The first driving device 4 is installed on the vehicle body 1 and is connected to the water gun 3. The first driving device 4 is used to automatically adjust the spraying angle of the water gun 3. The water gun 3 is connected to the water tank 2. The nozzle seat 32 is installed on the connecting wrist 31. The nozzle seat 32 has an arc-shaped mounting surface 3221, and the arc-shaped mounting surface 3221 protrudes toward the side close to the connecting wrist 31. The plurality of nozzles 33 are arranged at intervals on the arc-shaped mounting surface 3221.

[0030] According to the embodiment of the tunnel dust flushing vehicle of the present invention, since the curved mounting surface 3221 protrudes toward the side near the connecting arm 31, and multiple nozzles 33 are arranged at intervals on the curved mounting surface 3221, the water flow ejected by the multiple nozzles 33 forms a curved spray surface. When the tunnel dust flushing vehicle sprays the cables and pipes 7, the curved spray surface can reduce the dust flushing blind spots in the area of the cables and pipes 7, thereby improving the dust flushing effect. In addition, because the first drive device 4 can automatically adjust the spray angle of the water gun 3, there is no need for an additional operator to assist in controlling the water gun 3, saving manpower during the operation of the tunnel dust flushing vehicle.

[0031] It is understood that when the tunnel dust flushing vehicle sprays the cables and pipes 7, the curved mounting surface 3221 forms a semi-enclosed structure with the cylindrical pipe 7. When the multiple nozzles 33 spray water, the curved spray surface can fully flush the outer peripheral wall of the pipe 7. Compared to the solution where the spray surface formed by the multiple nozzles 33 is a flat surface, this application can flush the side of the pipe 7 that is adjacent to the wall, thereby reducing blind spots in the flushing.

[0032] Alternatively, as Figure 2 and Figure 3 As shown, the arc-shaped mounting surface 3221 is an arc surface, and the water outlets of the multiple nozzles 33 discharge water toward the center of the arc surface. It can be understood that the cross-section of the arc-shaped mounting surface 3221 is an arc. Since the water outlets of the multiple nozzles 33 discharge water toward the center of the arc surface, the flushing of the pipeline 7 can be more uniform, improving the flushing effect.

[0033] In one example, if Figure 2 As shown, the curvature of the arc-shaped mounting surface 3221 is a fixed value.

[0034] In other examples, such as Figure 3 As shown, the curvature of the arc-shaped mounting surface 3221 is adjustable. Preferably, the curvature of the arc-shaped mounting surface 3221 is adjustable, thereby facilitating the lane dust flushing vehicle to flush pipes 7 of different diameters, thereby improving the compatibility of the lane dust flushing vehicle.

[0035] Specifically, if Figure 3 As shown, the first driving device 4 also includes a first adjusting member 41, and the nozzle seat 32 includes a fixed frame 321 and a movable frame 322. The fixed frame 321 is installed on the connecting arm 31, and the movable frame 322 is connected to the movable frame 322 through the first adjusting member 41. The arc-shaped mounting surface 3221 is provided on the movable frame 322. The first adjusting member 41 is used to drive the movable frame 322 to move or deform to adjust the curvature of the arc-shaped mounting surface 3221.

[0036] It can be understood that when flushing the pipelines 7 of single-tube, double-tube and multi-tube, the arc-shaped mounting surface 3221 can be adjusted to different bending radians to adapt to different flushing conditions.

[0037] It should be noted that the first adjusting member 41 can drive the movable frame 322 to deflect or drive the movable frame 322 to deform, so as to adjust the bending radian of the arc-shaped mounting surface 3221. The present application does not specifically limit the adjustment method of the bending radian of the arc-shaped mounting surface 3221.

[0038] For example, as Figure 3 shown, the first adjusting member 41 includes a plurality of oil cylinders. The plurality of oil cylinders are arranged at intervals along the circumferential direction of the movable frame 322. One end of the oil cylinder is connected to the fixed frame 321, and the other end of the oil cylinder is connected to the edge of the movable frame 322. The oil cylinder can be telescopic to drive the movable frame 322 to deform, thereby adjusting the bending radian of the arc-shaped mounting surface 3221. By adjusting the bending radian of the arc-shaped mounting surface 3221 in the above manner, the roadway dust flushing vehicle of the embodiment of the present utility model has a simple structure, is convenient for processing and manufacturing, and has a good flushing effect.

[0039] In some embodiments, as Figure 1 and Figure 3 shown, the water gun 3 further includes a connecting arm 34. The connecting arm 34 is connected to the connecting wrist 31. The rotation angle of the connecting wrist 31 relative to the connecting arm 34 is adjustable. The first driving device 4 includes a second adjusting member 42. The second adjusting member 42 is connected to the connecting arm 34 and the vehicle body 1. The second adjusting member 42 is used to automatically adjust the pitching angle of the connecting arm 34. It can be understood that the roadway dust flushing vehicle of the embodiment of the present utility model can adjust the pitching angle of the water gun 3 without the operator controlling it. Through the second adjusting member 42, the pitching angle of the water gun 3 can be adjusted to change the spraying angle of the water gun 3.

[0040] In addition, since the rotation angle of the connecting wrist 31 relative to the connecting arm 34 is adjustable, when it is necessary to flush the pipelines 7 arranged in the horizontal direction or other directions, the rotation angle of the connecting wrist 31 can be adjusted to adapt to the actual flushing conditions.

[0041] For example, the second adjusting member 42 is an oil cylinder.

[0042] In some embodiments, as Figure 1 and Figure 4 shown, the roadway dust flushing vehicle further includes a water cannon 5 and a second driving device 6. The water cannon 5 is connected to the water tank 2. The second driving device 6 is arranged on the vehicle body 1 and is connected to the water cannon 5. The second driving device 6 is used to automatically adjust the spraying angle of the water cannon 5. It can be understood that the roadway dust flushing vehicle of the embodiment of the present utility model can adjust the spraying angle of the water cannon 5 without the operator controlling it. Through the second driving device 6, the spraying angle of the water cannon 5 can be adjusted, saving labor costs.

[0043] Specifically, as Figure 4 shown, the water cannon 5 includes a fixed pipe 51, a first pipe 52, and a second pipe 53. The second driving device 6 includes a third adjusting member 61 and a fourth adjusting member 62. The fixed pipe 51 is connected to the first pipe 52 through the third adjusting member 61. The rotation axis of the first pipe 52 extends in the vertical direction. The third adjusting member 61 is used to automatically adjust the rotation angle of the first pipe 52 relative to the fixed pipe 51. The second pipe 53 is connected to the first pipe 52 in the horizontal direction, and the second pipe 53 is connected to the first pipe 52 through the fourth adjusting member 62. The fourth adjusting member 62 is used to automatically adjust the pitching angle of the second pipe 53. A water spraying port of the water cannon 5 is provided on the second pipe 53.

[0044] It can be understood that the water tank 2 is communicated with the fixed pipe 51, and the fixed pipe 51, the first pipe 52, and the second pipe 53 are communicated in sequence. That is, the water in the water tank 2 flows through the fixed pipe 51, the first pipe 52, and the second pipe 53 in sequence and is discharged from the water spraying port on the second pipe 53. Since the third adjusting member 61 and the fourth adjusting member 62 can autonomously adjust the angles of the first pipe 52 and the second pipe 53, it is possible to control the spraying angle of the water cannon 5 without manual labor, saving labor costs.

[0045] For example, the third adjusting member 61 and the fourth adjusting member 62 can be driving motors or hydraulic motors, and the present utility model does not limit this.

[0046] Furthermore, as Figure 4 shown, the water cannon 5 further includes a control switch 54. The control switch 54 is installed on the second pipe 53 to control the opening and closing of the water spraying port, so as to facilitate the operator to control the water cannon 5.

[0047] In the example of the present utility model, a cab 11 is provided on the front side of the vehicle body 1. The water tank 2, the water gun 3, and the water cannon 5 are all installed on the rear side of the cab 11.

[0048] In summary, the roadway dust flushing vehicle of the embodiment of the present utility model has at least the following technical effects:

[0049] (1) The roadway dust flushing vehicle can be driven by only one driver to realize the flushing of the roadway pipeline 7 and the roadway wall, reducing the number of people and improving efficiency.

[0050] (2) The arc-shaped spraying surface of the water gun 3 can better adapt to the envelope of the pipeline 7 on the roadway, reducing the dust flushing dead angle.

[0051] (3) The application of the automatic water cannon 5 can realize the all-round dust flushing of the roadway, and reduce the use of operating personnel, reducing labor costs.
