Description
Technical Field
The invention relates to the field of snow melting vehicles, in particular to an anti-blocking and anti-freezing method and device for a snow melting vehicle.
Background
In the existing snow melting vehicle, high-pressure steam generated by a boiler is used for melting ice and snow on a road surface, and then an engine drives a fan to pump the melted ice and snow into a sewage tank through a pumping device, for example, the patent CN207277272U provides a snow melting vehicle and an anti-freezing pipeline structure thereof. However, when the environmental temperature is very low, the snow and ice layer on the ground is firmer, after the snow melting vehicle starts to operate, the fan or the motor has a lower rotating speed, so that the snow and ice can be broken poorly, meanwhile, the suction effect is not ideal, the pipeline of the suction device is easily blocked by the snow and ice, and the rolling brush device can be frozen due to the ice, so that the whole vehicle is broken down, and the normal operation is influenced.

the invention also provides an anti-blocking and anti-freezing device of the snow melting vehicle, which comprises a processor and a memory, wherein the memory stores instructions for realizing the following method by the processor:

Further, the suction device is controlled to reach maximum power before the suction device descends to the ground.
The invention has the beneficial effects that: before the snow melting vehicle works, the rotating speed of an engine is controlled to be a set rotating speed after a fan engine of the snow melting vehicle is started; the snow melting roller brush and the suction roller brush are controlled to reach a certain rotation speed while the snow melting device and the suction device are lowered. When the snow melting vehicle stops working, the rotating speed of the fan engine and the rotating speed of the rolling brush are reduced to idle speed or stop rotating after the snow melting device and the suction device are lifted in place.

Drawings
FIG. 1 is a schematic view of a snow melting vehicle according to the present invention;
In the figure: 1. an operation box; 2. a controller; 3. an engine; 4. a fan; 5. a sewage tank; 6. a snow melting device; 7. a snow-melting rolling brush; 8. a suction device; 9. sucking the rolling brush; 10. a boiler.
Detailed Description
the present invention will be described in further detail with reference to the accompanying drawings.
The existing snow melting vehicle is generally divided into two parts during operation, including a snow melting stage and a suction stage, wherein the snow melting stage is used for crushing ice and snow on the ground and spraying high-temperature steam, and then the suction stage is used for further crushing the ice and snow and sucking the crushed ice and snow and water into a carriage. In the actual operation process, the situation that the suction pipeline and the fan pipeline are easily blocked is found, and a large amount of ice and snow can be attached to the roller brush for breaking the ice and snow to cause the ice and snow to freeze.
The reason why the clogging and freezing occur is found by the researchers because the existing snow melting vehicle generally puts down the snow melting and sucking device in advance to contact with the snow and ice on the ground before the operation, and the engines of the snow melting rolling brush, the sucking rolling brush and the sucking fan are not started in the process, or even if the engines are started, the engines are at a low speed, and the speed is increased when the operation is started. Just because the rotational speed of round brush and fan is lower, it is not good to the broken effect that melts of ice and snow in the acceleration process, and the suction effect is also not ideal, and then has leaded to the freezing of pipeline jam and round brush.
In order to solve the problems, the invention provides a method and a device for preventing the snow melting vehicle from blocking and freezing.
As shown in fig. 1, the snow melting vehicle is provided with an operation box 1 for giving instructions to a controller 2 to start and stop an engine 3 and to raise and lower a snow melting device 6 and a suction device 8. The input end of the controller 2 is connected with the operation box 1 for receiving an action instruction, and the output end of the controller 2 is connected with the engine 3 for controlling the starting and stopping of the engine and the rotating speed of the engine; the output end of the controller 2 is connected with the hydraulic electromagnetic valves of the snow melting device 6 and the suction device 8, and is used for controlling the lifting and the falling of the snow melting device 6 and the suction device 8; the output end of the controller 2 is connected with the hydraulic electromagnetic valves of the snow-melting rolling brush 7 and the suction rolling brush 9 and is used for controlling the rotation of the snow-melting rolling brush 7 and the suction rolling brush 9; the output end of the controller 2 is connected with the boiler 10 for controlling the boiler 10 to generate high-pressure steam and conveying the steam to the snow melting device 6 for melting the ice and snow on the ground.
The specific control principle is as follows: an engine starting switch is turned on a panel of the operation box 1, the controller 2 controls the engine 3 to run and start after receiving a starting instruction, and meanwhile, the controller 2 controls the rotating speed of the engine 3 to automatically run to the maximum value within a specified time through a program; then, a descending switch of the snow melting and sucking device is opened on a panel of the operation box 1, after a descending instruction of the snow melting and sucking device is obtained by the controller 2, the snow melting rolling brushes 7 and the sucking rolling brushes 9 are controlled to rotate, the rotating speeds of the two groups of rolling brushes are the maximum at the moment, then the snow melting device 6 and the sucking device 8 are controlled to descend, a boiler operation switch is opened after the snow melting device 6 and the sucking device 8 descend, the boiler 10 operates and generates high-pressure steam, and at the moment, the whole vehicle reaches an operation state.
During operation, the snow melting rolling brush 7 breaks open snow and ice on the road surface, the boiler 10 transmits the generated high-pressure steam into the snow melting device 6, and the high-pressure steam melts the snow on the road surface; the engine 3 then drives the fan 4 to suck the melted water into the sewage tank 5 through the suction device 8, while the suction roller brush 9 crushes the non-melted lump of ice and snow again, after which the suction device 8 sucks the crushed ice and snow into the sewage tank 5 again, thereby completing the snow melting operation.
after the operation is finished, firstly, the boiler operation switch is closed, and the boiler 10 stops working; then, the controller 2 closes the snow melting rolling brush 7 and the suction rolling brush 9 through program control, and lifts the snow melting device 6 and the suction device 8; and after the completion, an engine stop switch is turned on, the engine 3 stops working when the rotating speed of the engine is reduced to the idle speed, and the whole vehicle operation is finished.
In other embodiments, the rotational speeds of the snow-melting roller brush and the suction roller brush may be the same or different; the rotating speed of the fan is not always the same as the time for the rolling brush to reach the set rotating speed; the speed of descent and the time of arrival at the ground of the snow melting and suction devices may be the same or different.
The above embodiments of the present invention are provided, but the present invention is not limited to the described embodiments, such as the specific selection of the rotation speed of the roller brush, the design of the height of the snow melting suction device when the snow melting suction device descends and ascends, and the technical scheme formed by the fine adjustment of the above embodiments still falls into the protection scope of the present invention.
