[0002] In winter, clearing snow from roads is an important part of municipal road maintenance and road safety. Existing road snow removal mostly uses a forklift to clear it section by section. However, this method of snow removal is easy to damage the forklift because the snow covers the road surface and the road is uneven, and it is difficult to clear the snow on the road surface one by one. Subsequently, it is necessary to spread salt on the road so that the snow left by the forklift on the road surface can be further removed by salt melting. Furthermore, there is another problem that the melted snow water freezes into ice in a low temperature environment, and the road is still slippery, and the factors of road accidents cannot be eliminated in a short time.

[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] As shown in the figure, a high-energy airflow snow removal system A high-energy airflow snow removal system includes a snowplow 1, a high-energy airflow generating device and a snowplow gun 2 arranged on the snowplow 1, the high-energy airflow generating device includes a gas tank 3, an electric air pump 4 for pumping air into the gas tank 3, and a power supply device 5, the gas tank 3 is provided with an electric heating device 6, the electric heating device 6 is connected to the power supply device 5, the snowplow gun 2 is connected to the gas tank 3 through a heat-resistant pipe, and the snowplow gun 2 is movably connected to the two side ends of the snowplow 1. The electric heating device 6 of course includes an on or off switch, which can be an electric heating wire or an electric heating tube. The power supply device 5 can be a diesel generator or a gasoline generator. Secondly, the pipeline connection of the electric air pump 4 to pump air into the gas tank 3 and the diesel generator power supply line connection are existing technologies and will not be repeated here. The electric heating wire or electric heating tube goes deep into the gas tank 3 to heat the gas, and this part is blocked by the gas tank 3. Figure 1 Not shown. Electric air pump 4 and power supply device 5

[0012] When in use, the electric air pump 4 fills the air into the gas tank 3, and the power supply device 5 supplies power to the electric heating device 6 to heat the compressed air in the gas tank 3, so that the gas tank 3 will store high-temperature and high-pressure gas, that is, high-energy gas. The gas tank 3 and the snow removal spray gun 2 are connected through a heat-resistant pipe, and the high-energy gas is ejected from the snow removal spray gun 2 to form a high-energy airflow, and the high-energy airflow blows the snow on the road to both ends of the road. Further, in order to be able to operate for a longer time, the present invention designs two gas tanks 3, namely the first gas tank 31 and the second gas tank 32, one of which is used normally while the other is replenished with gas for heating and energy, and the alternating replacement between the first gas tank 31 and the second gas tank 32 can be realized in real time according to actual conditions. More specifically, the first gas tank 31 and the second gas tank 32 are both connected to the snow removal spray gun 2, and a pneumatic conversion device for selecting the first gas tank 31 or the second gas tank 32 is connected between the first gas tank 31 and the second gas tank 32. Of course, in addition to the preferred pneumatic conversion device described below, a solenoid valve electronic control system can also be used, for example, two solenoid valves are respectively connected to the gas outlets of the first gas tank 31 and the second gas tank 32, and the two solenoid valves are selected to open and close, but the price is expensive and the circuit is complicated, and maintenance and modification are not possible. More importantly, it cannot automatically realize the free switching between the first gas tank 31 and the second gas tank 32, and can only be opened and closed by manual experience, resulting in a large waste of high-energy gas in the gas tank 3.

[0013] The pneumatic conversion device of the present invention is preferably configured as follows. Specifically, the pneumatic conversion device includes a three-way joint 7 connected to the gas outlet of the first gas tank 31, and the remaining two ends of the three-way joint 7 are respectively connected to a cylinder and a first gas one-way valve 8 for preventing the gas of the second gas tank 32 from entering the first gas tank 31, and an elastic element 15 is mounted on the cylinder rod; a mechanical valve 9 for controlling the gas outlet and deflation of the second gas tank 32 is provided at the gas outlet of the second gas tank 32, and the mechanical valve 9 includes a valve handle 91 connected to the cylinder rod, and the rear end of the mechanical valve 9 is connected to a second gas one-way valve 10 for preventing the gas of the first gas tank 31 from entering the second gas tank 32. The elastic element 15 is preferably a cylindrical spring, also known as a tower spring.

[0014] During use, when the gas in the first gas tank 31 is at high energy, the air pressure at the cylinder inlet forces the cylinder rod to be in a retracted state, and the mechanical valve 9 is in a closed state; when the gas in the first gas tank 31 is at low energy, the cylinder rod of the cylinder overcomes the effect of the low-energy gas on the cylinder under the action of the elastic element 15, so that the cylinder rod extends, and the extension of the cylinder rod drives the valve handle 91 of the mechanical valve 9 upward, and the mechanical valve 9 is opened. At the same time, since the pressure of the second gas tank 32 is greater than that of the first gas tank 31, the first gas check valve 8 is in a cut-off state, and the second gas check valve 10 is in an open state. When the first gas tank 31 is filled with gas again and is in high energy after heating, the mechanical valve 9 is in a closed state again. By alternating in this way, automatic real-time switching between the first gas tank 31 and the second gas tank 32 can be achieved.

[0015] Preferably, the snow-removing spray gun 2 includes a gun rod 21, a gas nozzle 22 disposed at the lower end of the gun rod 21, and a support mechanism for adjusting the working position of the snow-removing spray gun 2, the support mechanism includes a support shaft 24 for supporting the gun rod base 23 and fixedly disposed on the snow-removing vehicle 1 for supporting the base, the support shaft 24 is hinged with the base 23, and ratchets 25 are provided at both ends of the base, and a pawl 26 that cooperates with the ratchet 25 is connected to the support shaft 24, and a stopper 27 is provided at the end of the pawl 26. When in use, the height of the snow-removing spray gun 2 from the ground can be adjusted by the upper and lower positions of the gun rod 21 on the gun rod base 23, and the spraying angle of the snow-removing spray gun 2 can be adjusted by adjusting the rotation position of the base on the support shaft 24. After adjustment, the positioning can be achieved by the cooperation of the ratchet and the pawl 26 and fixed by the stopper 27, and the stopper 27 is a bolt or a screw.

[0016] Preferably, the snow removal spray gun 2 is provided with a manual gas pressure regulating valve 11 to fine-tune the size of the airflow so as to control the position where the snow and ice are blown off and fall to the ground.

[0017] Preferably, it also includes a control system for controlling the temperature and pressure of the gas inside the gas tank 3, the control system includes a control unit, a temperature sensor 12 for monitoring the temperature of the gas in the gas tank 3, and a pressure sensor 13 for monitoring the pressure of the gas in the gas tank 3. The temperature sensor 12 and the pressure sensor 13 are electrically connected to the signal input end of the control unit, and the signal output end of the control unit is electrically connected to the power supply device 5 and the electric air pump 4. The control unit is preferably a PLC controller 14 or an 8051 single-chip microcomputer. The temperature sensor 12 and the pressure sensor 13 input signals to control the electric air pump 4 to replenish gas and
