[0030] Combination Figure 1 andFigure 2 As shown in the drawings, a road drying module device of a gas jet snow-removing vehicle, characterized in that, comprising a jet flow deflection nozzle 10, the outlet end of which is provided with a jet flow straight jet port 106, the axis of the jet flow straight jet port 106 is inclined backward and downward; a jet flow primary wave reflection cover 20 is connected to the jet flow deflection nozzle 10, a jet flow long wave reflection cover 30, a jet flow downhill cover 40 and a jet flow outlet cover 50 are sequentially connected to the rear end of the jet flow primary wave reflection cover 20.

[0031] The top surface of the tail end of the jet flow primary wave reflection cover 20 is provided with a primary wave reflection surface 203 inclined downward from front to back, which is used for primary reflection of the gas jet reflected by the road surface to form a jet flow primary wave.

[0032] The top surface of the jet flow long wave reflection cover 30 is provided with a long wave reflection surface 302 inclined upward from front to back, which is used for secondary reflection of the jet flow primary wave reflected by the road surface to form a jet flow extended wave, prolong the reflection length and weaken the gas shock wave.

[0033] The top surface of the jet flow downhill cover 40 is provided with a downhill surface 402 inclined downward from front to back, forming a closed structure.

[0034] The top surface of the jet flow outlet cover 50 is a horizontal surface, which is used for reflection of the jet flow extended wave reflected by the road surface.

[0035] In order to describe the structure, function and positional relationship of each component, the gas jet emitted from different parts of the jet flow straight jet port 106 is divided into a gas jet bottom bundle A, a gas jet middle bundle B and a gas jet top bundle C, which are respectively represented by A, B and C. Figure 1 The gas jet bottom bundle A is the gas jet bundle emitted along the front side wall of the jet flow straight jet port, the gas jet middle bundle B is the gas jet bundle emitted from the central part of the jet flow straight jet port, and the gas jet top bundle C is the gas jet bundle emitted along the rear side wall of the jet flow straight jet port.

[0036] In combination with Figure 1 As shown in the drawings, in order to avoid plugging and pressure accumulation of the gas turbine high-speed jet tail gas, and to avoid the back pressure effect on the gas turbine, the inclination angle of the jet flow straight jet port 106 is ensured to prevent the reflected gas jet after impacting the road surface from entering the jet flow straight jet port 106. By ensuring the inclination angle of the jet flow straight jet port 106, it is avoided that the gas jet emitted from the jet flow straight jet port 106 enters the jet flow straight jet port 106 again after being reflected by the ground.

[0037] In order to ensure the reflection effect of the jet flow primary wave reflection cover 20 and shorten the overall length of the jet flow primary wave reflection cover 20 to a certain extent, the inclination angle and length of the primary wave reflection surface 203 need to be controlled. Specifically, the length of the rear extension of the primary wave reflection surface 203 ensures that the reflected flow after the gas jet middle bundle B impacts the road surface falls into the primary wave reflection surface 203, as shown in the drawings.Figure 1 As shown, the landing position of the middle beam B of the gas jet after reflection on the ground is represented by F on the primary wave reflection surface 203, thus the length of the rear extension of the primary wave reflection surface 203 should only ensure that the position F is on the primary wave reflection surface 203. Further, the length of the front extension of the primary wave reflection surface 203 should ensure that the reflected flow of the bottom beam A of the gas jet after reflection on the ground falls into the primary wave reflection surface 203, specifically, the landing position of the bottom beam A of the gas jet after reflection on the ground is represented by E on the primary wave reflection surface 203, thus the length of the front extension of the primary wave reflection surface 203 should only ensure that the position E is on the primary wave reflection surface 203. In the case that the inclination angle of the jet straight jetting port 106 is determined, the incidence angle and reflection angle of the bottom beam A and the middle beam B of the gas jet are also determined, and the inclination angle and length of the primary wave reflection surface 203 can be determined by using the landing positions E and F of the bottom beam A and the middle beam B of the gas jet after reflection on the ground.

[0038] In combination Figure 1 As shown, the jet deflection nozzle 10 comprises a vertical flow guide pipe 102 and a jet straight jetting port 106 at the outlet end; a deflection elbow 105 is arranged at the front end of the jet straight jetting port 106, and a elbow flange 104 is arranged at the front end of the deflection elbow 105; a flow guide pipe lower flange 103 is arranged at the lower end of the vertical flow guide pipe 102; and the elbow flange 104 is connected with the flow guide pipe lower flange 103. The vertical flow guide pipe 102 is used to be connected with the gas jet flow distributor 60 on the vehicle body, and a flow guide pipe upper flange 101 is arranged at the upper part of the vertical flow guide pipe 102 to be connected with the flange of the gas jet flow distributor 60. The jet straight jetting port 106 is connected with the vertical flow guide pipe 102 through the deflection elbow 105, so that the inclination angle of the jet straight jetting port 106 can be set, and the connection and replacement of the jet straight jetting port 106 are facilitated by connecting the elbow flange 104 with the flow guide pipe lower flange 103.

[0039] The deflection elbow 105 is used to deflect the gas jet flow under the vertical flow guide pipe 102 by a certain angle and then jet out from the jet straight jetting port 106, and the tail end of the front side wall of the jet straight jetting port 106 intersects with the center line D of the vertical flow guide pipe 102, so that the gas jet flow in the vertical flow guide pipe 102 can be completely deflected after being jetted out from the jet straight jetting port 106.

[0040] The horizontal length of the long wave reflection surface 302 in the jet long wave reflection cover 30 should not be too long, and should meet the reasonable spacing between the jet primary wave reflection cover 20 and the jet downhill cover 40, thus the horizontal length and the inclination angle of the long wave reflection surface 302 need to be designed. In combination Figure 1As shown, the rearward extension length of the long-wave reflector 302 ensures that the reflected flow of the gas jet top beam C after impacting the road surface falls within the long-wave reflector 302. Specifically, the landing point of the gas jet top beam C after impacting the road surface and reflecting to the long-wave reflector 302 is denoted by G. Therefore, the rearward extension length of the long-wave reflector 302 only needs to ensure that position G is located on the long-wave reflector 302. Furthermore, regarding the angle of the long-wave reflector 302, it is required that the landing point of the gas jet middle beam B after being reflected to the ground by the long-wave reflector 302 and then reflected again is located within the top surface of the jet exit mask 50. Specifically, the position of the gas jet middle beam B reaching the jet exit mask 50 is as follows... Figure 1 As shown in Figure H, position H is required to be located within the top surface of the jet exit mask 50. With the initial wave reflector 203 having a fixed tilt angle, the reflection angle of the gas jet beam B is also fixed. Since the height of the top surface of the jet exit mask 50 is fixed, the tilt angle of the long-wave reflector 302 can be controlled by adjusting the position H of the gas jet beam B's reflection point relative to the top surface of the jet exit mask 50. By controlling the length and tilt angle of the long-wave reflector 302, the gas jet is made as completely reflected as possible by the jet long-wave reflector 30, reducing turbulence.

[0041] In this embodiment, the downward tilt angle of the downward slope surface 402 in the jet downslope cover 40 is determined by the angle after the top beam of the gas jet C is reflected by the long-wave reflector 302. Specifically, the long-wave reflector 302 is parallel to the jet beam after the top beam of the gas jet C is reflected by the long-wave reflector 302, that is, the reflected stream of the top beam of the gas jet C flows parallel downwards along the downward slope surface 402. The length of the backward extension of the downward slope surface 402 in the jet downslope cover 40 is not greater than the landing point of the middle beam of the gas jet B after being reflected to the ground by the long-wave reflector 302, that is, to ensure that the reflection point of the middle beam of the gas jet B reaches the position H of the top surface of the jet exit mask 50, and the middle beam of the gas jet B passes through the jet downslope cover 40, thus determining the length of the downward slope surface 402. The downward slope surface 402 only reflects the bottom beam of the gas jet A, and bears the least impact. The cavity formed by the downward slope surface 402 and its two side baffles is conducive to the heat accumulation drying operation.

[0042] The jet initial wave reflection cover 20 comprises a round-to-square section 202 and initial wave side arches 204 connected to the lower sides of the round-to-square section 202, and the connecting position of the round-to-square section 202 and the initial wave side arches 204 is treated with a circular arc to avoid turbulence; the initial wave reflection surface 203 is connected to the bottom of the tail end of the initial wave side arches 204, and the front end of the initial wave reflection surface 203 is connected to the round-to-square section 202; the round-to-square section 202 gradually changes from a circular ring to a square from top to bottom, and the concave edges of the inner surface of the round-to-square section 202 are treated with an arc surface to ensure that no turbulence occurs in the internal gas; the jet direct injection port 106 is located in the cover formed by the round-to-square section 202 and the initial wave side arches 204; the first flange 201 is arranged on the top of the round-to-square section 202, and the first flange 201 is connected to the lower flange 103 of the flow guide pipe. The second flange 205 is arranged at the tail end of the jet initial wave reflection cover 20, and the jet initial wave reflection cover 20 has an open bottom structure, the front end of the initial wave side arch 204 extends forward to leave enough space for the airflow fan to scatter forward of the vehicle, so as to impact and preheat the working area in advance.

[0043] The jet long wave reflection cover 30 comprises a long wave reflection surface 302 and long wave side arches 303 arranged on the two sides of the long wave reflection surface 302, the transition position of the long wave reflection surface 302 and the long wave side arches 303 is treated with a circular arc to avoid turbulence, the third flange 301 is arranged at the front end of the jet long wave reflection cover 30, and the fourth flange 304 is arranged at the rear end of the jet long wave reflection cover 30; both ends and the lower end of the jet long wave reflection cover 30 are open structures.

[0044] The jet downhill cover 40 comprises a downhill surface 402 and downhill side arches 403 arranged on the two sides of the downhill surface 402, the connecting position of the downhill surface 402 and the downhill side arches 403 is treated with a circular arc to avoid turbulence, the fifth flange 401 is arranged at the front end of the jet downhill cover 40, and the sixth flange 402 is arranged at the rear end of the jet downhill cover 40; both ends and the lower end of the jet downhill cover 40 are open structures.

[0045] The jet outlet cover 50 comprises a seventh flange 501 and an outlet cover body 502, the top surface of the outlet cover body 502 is a plane, and both ends and the lower part are open structures. The jet outlet cover 50 mainly receives the road reflection jet of the beam B of the gas jet to be reflected out of the jet outlet cover 50.

[0046] The jet initial wave reflector 20 and the jet long wave reflector 30 are connected by a second flange 205 and a third flange 301; the jet long wave reflector 30 and the jet downslope reflector are connected by a fourth flange 304 and a fifth flange 401; the jet downslope reflector 40 and the jet exit cover 50 are connected by a sixth flange 402 and a seventh flange 501. Each section of the cover is connected by a flange structure, which is simple in structure. Furthermore, the interconnected flange structures also act as reinforcing ribs, strengthening each section of the cover and further preventing deformation under high temperature and pressure. After the flange connections between each section of the cover, they can be fixed by an external suspension support (not shown in the figure). The external suspension support is connected to the core engine compartment of the vehicle body. The upward impact force of the gas on each section of the cover is borne by the weight of the trailer, reducing the impact of the gas-reflected airflow on the reflective surface and thus reducing structural deformation.

[0047] Combination Figure 1 As shown, counterweights (not shown in the figure) are respectively provided on the jet initial wave reflector 20, the jet long wave reflector 30, the jet downward slope cover 40 and the jet exit cover 50. These counterweights can reduce the impact of the gas jet reflected airflow on each section of the cover and suppress the structural deformation caused by the upward tilting of the cover by the counterweight weight.

[0048] Combination Figure 2 As shown, the internal widths of the two sides of the jet initial wave reflector 20 are L1, the internal widths of the two sides of the jet long wave reflector 30 are L2, the internal widths of the two sides of the jet downward slope reflector 40 are L3, and the internal widths of the two sides of the jet exit mask 50 are L4, where L1 < L2 < L3 < L4. Therefore, the lower part of each cover forms an enlarged component structure, which can prevent the ice, snow, and meltwater blown backward from remaining on the road behind the vehicle and causing secondary disasters.
