Description

Technical Field

[0001] The present invention relates to the technical field of road deicing, and in particular to a non-destructive road deicing device and a control method. Background Art

[0002] In the cold winter, due to the influence of severe weather such as ice and snow, the road surface will be frozen. Ice on the road surface is one of the main causes of traffic accidents in winter. The ice layer on the road surface reduces the friction system of the road surface, resulting in insufficient tire grip, idling, and side slipping during the driving process of motor vehicles. Therefore, in order to effectively prevent winter traffic accidents and ensure the safe driving of motor vehicle drivers in severe weather such as ice and snow, it is necessary to clean the road surface in time; At present, the main measures to remove ice from roads are to use various large-scale equipment such as plowshare snowplows, rotor snowplows, and sweeping snowplows. Such equipment has a good effect on removing snow, but its ability to remove ice from roads is relatively limited, and it may cause secondary damage to the road surface during the deicing process. Therefore, it is necessary to study and design a deicing device that can efficiently remove ice from the road surface and avoid secondary damage to the road surface. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a non-destructive road deicing device and a control method, which solves the problems that the existing deicing vehicles have unsatisfactory deicing effect, low efficiency, and easy damage to the road surface.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A non-destructive road deicing device comprises: a truck type vehicle, a primary ice crushing wheel assembly, a secondary ice crushing wheel assembly, an ultrasonic thickness sensor, a telescopic negative pressure collection device, a control unit, a generator, a crushed ice collection box, a heating device, a Hall sensor and a connecting arm, wherein the primary ice crushing wheel assembly and the secondary ice crushing wheel assembly are connected at the front end of the vehicle through the connecting arm, an ultrasonic thickness sensor is installed below the front end of the connecting arm, a telescopic negative pressure collection device is installed between the wheels of the vehicle, the crushed ice collection box, the control unit and the generator are installed above the vehicle, and the telescopic negative pressure collection device is connected to the crushed ice collection box; The first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly are both composed of an ice-crushing wheel body and an ice-crushing wheel blade head. Multiple groups of hydraulic structures are installed inside the ice-crushing wheel body. The output ends of the multiple groups of hydraulic structures are connected to the ice-crushing wheel blade heads. A blade head extension hole is provided at a position corresponding to the ice-crushing wheel blade head on the surface of the ice-crushing wheel body. The heating device is composed of a plurality of heating plates, which are installed on the surface of the secondary ice crushing wheel body and located between the blades of the secondary ice crushing wheel; Hall sensors are installed on the sides of the primary ice-crushing wheel body and the secondary ice-crushing wheel body.

[0005] Furthermore, the connecting arm is installed on the front side of the vehicle, and is composed of a main arm, a telescopic auxiliary arm and a hydraulic device. The bottom end of the main arm is connected to the primary ice-crushing wheel assembly, the other end of the main arm is connected to the front end of the vehicle, the bottom end of the auxiliary arm is connected to the secondary ice-crushing wheel assembly, and the top end of the auxiliary arm is connected to the main arm through a rotating power shaft; The output end of the hydraulic device is fixedly connected to the main arm, and the other end is fixedly connected to the front end of the carrier.

[0006] Furthermore, the ultrasonic thickness sensor, the heating device, the Hall sensor, the negative pressure absorption device, the generator, the hydraulic structure inside the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly, and the hydraulic device of the connecting arm are connected to the control unit via wires; Furthermore, the connecting arm and its interior are provided with mechanical structures and circuits for controlling the operation of the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly; The connecting arms are a pair and are symmetrically arranged and installed at the front ends of both sides of the vehicle. Motors are installed on the inner sides of one main arm and one auxiliary arm, and the output ends of the motors are fixedly connected to the central axes of the primary ice crushing wheel assembly and the secondary ice crushing wheel assembly.

[0007] Furthermore, the generator provides electrical energy for the device.

[0008] Furthermore, the telescopic negative pressure absorption device is installed under the vehicle in two groups, which are respectively located between the tires of the vehicle and are connected to the crushed ice collection box installed above the vehicle through a hose.

[0009] A control method for a non-destructive road deicing device comprises the following steps: S1: The vehicle drives onto an icy road, starts the device, and the ultrasonic thickness sensor detects the thickness of the ice layer and transmits the ice thickness information to the control unit; S2: When the ice thickness detected by the ultrasonic thickness sensor is greater than the minimum ice thickness set in the control unit, the control unit analyzes and determines that road deicing is required. The control unit controls the ice-crushing wheel blades in the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly to extend to a preset length. Control the rotation of the primary ice crushing wheel assembly and the secondary ice crushing wheel assembly. Control and start the heating device on the surface of the secondary ice crushing wheel body. Control the telescopic negative pressure absorption device to reach the required height and delay the start of the negative pressure absorption device. The first-stage ice-crushing wheel assembly is controlled to press down, and the ultrasonic thickness sensor continuously monitors the thickness of the ice layer.

[0010] S3: When the ultrasonic thickness sensor continuously monitors that the ice thickness is less than or equal to the minimum ice thickness set in the control unit, the first-stage ice-crushing wheel assembly stops pressing down, and when the vehicle moves forward, the second-stage ice-crushing wheel assembly is controlled to reach the required height with a delay. The Hall sensors located on the sides of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly monitor the rotation speed of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly, and transmit the rotation speed information to the control unit; S4: When the vehicle moves forward, the heat generated by the secondary ice-crushing wheel assembly and the heating device further crushes and melts the ice; When the vehicle moves forward, the negative pressure absorption device moves into the ice-water mixture mainly composed of liquid water, which is formed by crushing and melting the secondary ice-crushing wheel assembly and the heating device thereon, and sucks it into the crushed ice collection box through a hose; At this time, if the ice thickness value monitored by the ultrasonic thickness sensor changes, the height of the first-level ice crushing wheel assembly and the second-level ice crushing wheel assembly needs to be adjusted to ensure that the remaining ice thickness is equal to the minimum ice thickness set in the control unit to ensure the deicing effect and no damage to the road surface; S5: The control unit constantly compares the actual speed information with the no-load speed value. If the actual speeds of the primary ice crushing wheel assembly and the secondary ice crushing wheel assembly are both less than the no-load speed values ​​recorded in the control unit, the de-icing operation continues; If the actual rotation speeds of the primary and secondary ice-crushing wheel assemblies are greater than or equal to the no-load rotation speed values ​​recorded in the control unit, the control unit issues a command to stop the rotation of the primary and secondary ice-crushing wheel assemblies, a command to retract the blades, a command to delay stopping the operation of the heating device, and controls the hydraulic device of the connecting arm to lift up, the telescopic negative pressure absorption device to delay stopping the operation, and restore to the initial height, and the de-icing work is completed; Furthermore, during the vehicle's forward deicing process, the rotation speed of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly can be monitored by the Hall sensor. By comparing the actual rotation speed with the given rotation speed, the deicing work of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly can be started and stopped. The deicing work can also be started and stopped by manual control.

[0011] Furthermore, the minimum value set for the ice thickness in the control unit can be adjusted and preset according to actual conditions. Beneficial Effects

[0012] The above technical solution of the present invention has at least one of the following beneficial effects: 1. The present invention firstly breaks the ice layer on a large area of ​​the road into large-sized ice cubes through the primary ice-crushing wheel assembly, and then breaks the large-sized ice cubes into small-sized ice cubes through the secondary ice-crushing wheel assembly. At the same time, the small-sized ice cubes and the thin ice layer on the road are melted by the heating device. Finally, the melted ice-water mixture is absorbed into the storage box through two negative pressure absorption devices for centralized storage. In the de-icing work of the road, it can not only ensure that the road surface is clean and free of ice and water residue, but also improve the efficiency of the de-icing work.

[0013] 2. The present invention monitors the thickness of the ice layer on the road surface through an ultrasonic thickness sensor, and uses this as a trigger condition to control the height of the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly, so as to prevent the ice-crushing wheel head from cutting the road surface when cutting the ice layer or ice cubes, thereby avoiding damage to the road surface.

[0014] 3. The present invention uses the rotation speed information monitored by the Hall sensors on the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly as the working condition for starting the primary ice-crushing wheel assembly and the secondary ice-crushing wheel assembly, thereby solving the problem that current de-icing equipment such as de-icing vehicles need to rely on manual judgment when in use, resulting in poor accuracy and low efficiency.

[0022] As a preferred option, please refer to Figure 2 , Figure 3 The connecting arm 11 and its interior are provided with a mechanical structure and circuit for controlling the operation of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3; The connecting arms 11 are a pair and are symmetrically arranged and installed at the front ends of both sides of the carrier 1.

[0023] As a preferred option, please refer to Figure 1 The telescopic negative pressure absorption device 5 is installed under the vehicle 1, and is divided into two groups, which are respectively located between the tires of the vehicle 1 and are connected to the crushed ice collection box 8 installed above the vehicle 1 through a hose.

[0024] In specific applications, the telescopic auxiliary arm 112 and the telescopic negative pressure absorption device 5 can use an electric push rod to achieve the telescopic function, but it is not limited to this; the negative pressure absorption device is similar to the vacuum cleaner device in the prior art.

[0025] A control method for a non-destructive road deicing device comprises the following steps: S1: The vehicle 1 drives onto an icy road surface, starts the device, and the ultrasonic thickness sensor 4 detects the thickness of the ice layer and transmits the ice thickness information to the control unit 6; S2: When the ice thickness detected by the ultrasonic thickness sensor 4 is greater than the minimum ice thickness value set in the control unit, the control unit 6 analyzes and determines that road deicing is required. The control unit 6 controls the ice-crushing wheel blades inside the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 to extend to a preset length. Control the rotation of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3, Control and start the heating device 9 on the surface of the secondary ice crushing wheel body 31, Control the telescopic negative pressure absorption device to reach the required height and delay the start of the negative pressure absorption device. The first-stage ice-crushing wheel assembly 2 is controlled to be pressed downward, and at this time, the ultrasonic thickness sensor 4 continuously monitors the thickness of the ice layer.

[0026] S3: When the ultrasonic thickness sensor 4 continuously monitors the ice thickness to be less than or equal to the minimum ice thickness set in the control unit 6, the primary ice-crushing wheel assembly 2 stops pressing down, and when the vehicle 1 moves forward, the secondary ice-crushing wheel assembly 3 is controlled to reach the required height with a delay. The Hall sensor 10 located on the side of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 monitors the rotation speed of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3, and transmits the rotation speed information to the control unit 6; S4: When the vehicle 1 moves forward, the heat generated by the secondary ice-crushing wheel assembly 3 and the heating device 9 further crushes and melts the ice cubes; When the vehicle 1 moves forward, the negative pressure absorption device 5 moves into the ice-water mixture mainly composed of liquid water, which is formed by crushing and melting the ice by the secondary ice-crushing wheel assembly 3 and the heating device 9 thereon, and sucks it into the crushed ice collection box 8 through the hose; At this time, if the ice thickness value monitored by the ultrasonic thickness sensor 4 changes, it is necessary to adjust the height of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3 to ensure that the remaining ice thickness is equal to the minimum ice thickness set in the control unit 6 to ensure the deicing effect and the road surface is not damaged; S5: The control unit 6 constantly compares the actual speed information with the no-load speed value. If the actual speeds of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are both less than the no-load speed values ​​recorded in the control unit 6, the de-icing operation continues; If the actual rotation speeds of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are both greater than or equal to the no-load rotation speed values ​​recorded in the control unit 6, the control unit 6 issues a command to stop the rotation of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3, a command to retract the blades, a command to delay stopping the operation of the heating device 9, and controls the hydraulic device 113 of the connecting arm to lift up, the telescopic negative pressure absorption device 5 to delay stopping the operation, and restore to the initial height, and the deicing work is completed; Furthermore, when the vehicle 1 is moving forward and de-icing, the rotation speed of the first-stage ice-crushing wheel assembly 2 and the second-stage ice-crushing wheel assembly 3 can be monitored by the Hall sensor 10. By comparing the actual rotation speed with the given rotation speed, the de-icing operation of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly can be started and stopped. The de-icing operation can also be started and stopped by manual control.

[0027] Furthermore, the minimum value set for the ice thickness in the control unit 6 can be adjusted and preset according to actual conditions.

[0028] Working principle: See also Figure 1-Figure 8 When the truck vehicle 1 moves forward, the generator 7 provides power to the device, starts the device, and the ultrasonic thickness sensor 4 detects the thickness of the ice layer in front and transmits the ice thickness information to the control unit 6. The control unit 6 receives the ice thickness information detected by the ultrasonic thickness sensor 4. In actual applications, the control unit can use a Cortex-A53 processor, but is not limited to it; When the ice thickness detected by the ultrasonic thickness sensor 4 is greater than the minimum ice thickness value set in the control unit, the control unit 6 determines that there is ice in front of the vehicle 1 after logical analysis. At this time, the control unit 6 sends a control instruction to the hydraulic structure inside the primary ice-crushing wheel body 21 and the secondary ice-crushing wheel body 31 to control the ice-crushing wheel blade to extend to a preset length. Control to start the heating device 9 on the surface of the secondary ice-crushing wheel body 31, and output a start command to the motor 114 at the bottom of the main arm 111 and the auxiliary arm 112 of the connecting arm 11, control the rotation of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3, send a start command to the electric push rod of the telescopic negative pressure absorption structure 5, drive the telescopic negative pressure absorption structure 5 to extend downward, and delay the start of the negative pressure absorption device; The first-stage ice-crushing wheel assembly 2 receives the instruction of the control unit 6 to perform circular motion, and at the same time drives the first-stage ice-crushing wheel blade 22 extending to a preset length to rotate. The control unit 6 controls the output end of the hydraulic device 113 to drive the main arm 111 of the connecting arm to press down to cut the ice layer on the road surface. The first-stage ice-crushing wheel assembly 2 destroys the continuous ice layer on the road surface and cuts it into large-sized crushed ice. At this time, a thin layer of ice remains on the road surface, and the large-sized crushed ice is located between the first-stage ice-crushing wheel assembly 2 and the second-stage ice-crushing wheel assembly 3.

[0029] The vehicle 1 moves forward and continuously cuts the continuous ice layer on the road surface. During this process, the ultrasonic thickness sensor 4 continuously monitors the thickness of the ice layer and transmits the information of the thickness of the ice layer to the control unit 6 in real time.

[0030] The control unit 6 controls the electric push rod inside the auxiliary arm 112 to drive the auxiliary arm 112 to extend downward to the required height. The secondary ice-crushing wheel body 31 drives the secondary ice-crushing wheel blade 32 that has been extended to a preset length to rotate and perform circular motion to cut large-sized crushed ice. The secondary ice-crushing wheel assembly 3 cuts the large-sized crushed ice into small-sized crushed ice.

[0031] When the vehicle 1 moves forward, the secondary ice-crushing wheel assembly 3 continues to cut the large-sized crushed ice and the thin ice close to the road surface cut by the primary ice-crushing wheel assembly 2. When the secondary ice-crushing wheel assembly 3 is working, the heating device 9 located on the surface of the secondary ice-crushing wheel body 31 starts to work, and the heat of the heating plate is transferred along the secondary ice-crushing wheel blade 32 to the thin ice layer and small-sized crushed ice close to the road surface. At the same time, the heating plate is in direct contact with the small-sized crushed ice and transfers the heat directly to the small-sized crushed ice. With the support of these two heating methods, the small-sized crushed ice and the thin ice layer close to the road surface melt quickly. When the vehicle 1 moves forward, the telescopic negative pressure absorption device 5 located between the wheels of the vehicle 1 moves to the ice-water mixture formed by the crushing and melting of the secondary ice-crushing wheel assembly 3 and the heating device 9 thereon, and approaches the ice-water mixture, and sucks the ice-water mixture into the crushed ice collection box 8 through the hose. The two-stage negative pressure absorption device 5 between the wheels of the vehicle 1 can ensure that there is no residue of the ice-water mixture on the road surface; At this time, if the ice thickness value monitored by the ultrasonic thickness sensor 4 changes, it is necessary to adjust the height of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3 to ensure that the remaining ice thickness is equal to the minimum ice thickness set in the control unit 6 to ensure the deicing effect and the road surface is not damaged; When the vehicle 1 moves forward, the Hall sensor 10 located on the side of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3 monitors the rotation speed of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3, and transmits the rotation speed information to the control unit 6. The control unit 6 receives the monitoring signal of the Hall sensor 10. If the actual rotation speeds of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are both less than the no-load rotation speed given by the control unit 6, the control unit 6 determines that there is still an ice layer ahead, and the de-icing operation continues; If the actual rotation speeds of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are both greater than or equal to the given no-load rotation speed, the control unit 6 determines that there is no ice layer ahead, and issues a command to stop the rotation of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3, a command to retract the blade head, a command to delay stopping the operation of the heating device 9, and controls the hydraulic device 113 of the connecting arm to work, lifts the connecting arm 11, delays stopping the absorption work of the telescopic negative pressure absorption device 5, controls the electric push rod to retract, and the telescopic negative pressure absorption device 5 returns to the initial position, and the deicing work is finished; Furthermore, when the vehicle 1 is moving forward and de-icing, the rotation speed of the first-stage ice-crushing wheel assembly 2 and the second-stage ice-crushing wheel assembly 3 can be monitored by the Hall sensor 10. By comparing the actual rotation speed with the given no-load rotation speed, the de-icing operation of the first-stage ice-crushing wheel assembly and the second-stage ice-crushing wheel assembly can be started and stopped. The de-icing operation can also be started and stopped by manual control.

[0032] Furthermore, the minimum value set for the ice thickness in the control unit 6 can be adjusted and preset according to actual conditions.

[0033] In summary, 1. If the ultrasonic thickness sensor 4 detects that the thickness of the ice layer is greater than the minimum ice thickness value set by the control unit 6, the device starts working and is in deicing operation; 2. If the rotation speed values ​​monitored by the Hall sensors 10 on the sides of the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are both less than the no-load rotation speed values ​​recorded in the control unit 6, the deicing operation continues and the device is in the deicing operation; 3. If the ice crushing wheel speed values ​​monitored by the Hall sensors 10 on the sides of the primary ice crushing wheel assembly 2 and the secondary ice crushing wheel assembly 3 are both greater than or equal to the no-load speed values ​​recorded in the control unit 6, the control unit 6 controls the device to stop deicing.

[0034] It should be noted that the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel assembly 3 are respectively equipped with Hall sensors. When the control unit 6 determines that the rotation speed of the primary ice-crushing wheel assembly 2 is less than the no-load rotation speed value, if the device stops working, since the ice between the primary ice-crushing wheel assembly 2 and the secondary ice-crushing wheel 3 is not cleaned up, it is necessary to meet the condition that the two Hall sensors 10 are both greater than or equal to the no-load rotation speed value, and the control unit 6 controls the device to stop the de-icing work, so that no ice on the road surface remains and is cleaned up.

[0035] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
