A microwave deicer

technical field

The utility model relates to a microwave deicing vehicle.

Background technique

Studies have shown that road conditions play a large role in the causes of traffic accidents, especially in cold regions. In cold areas in winter, if the snow on the road cannot be cleaned up in time after snowfall, it will form snow or even ice on the road after being crushed by vehicles; resulting in a significantly lower coefficient of friction on the road than in other seasons, making it easier for vehicles to walk , Braking is difficult, has a strong impact on driving safety, easily leads to traffic jams, and frequent traffic accidents have caused great losses to people's lives and property. Statistics show that in cold regions, traffic accidents in winter are about 20% higher than in other seasons.

In most areas of northern my country, the winter time is relatively long, and some areas experience a snowfall period of 3 to 5 months every year. important. In the past, snow removal was mainly done manually, which was time-consuming, labor-intensive, unsafe, low-efficiency, and the area to be removed was very limited.

In order to overcome the disadvantages of manually removing ice and snow, people have explored and developed many effective methods for removing ice and snow and supporting machinery for removing ice and snow, some of which methods and equipment have been applied to actual work.

Physical melting is to melt the snow or ice on the road surface by heating.

One is electric heating. The mechanism of melting ice and snow using conductive concrete. The resistivity of ordinary concrete is generally in the range of 106-109Ω·cm, which is neither an insulator nor a good conductor. Conductive concrete is a new type of cement-based composite material made by adding a certain amount of conductive component materials to ordinary concrete. The conductive component materials greatly improve the conductivity of concrete, thus becoming a conductor with good electrical conductivity. Use conductive concrete to melt snow and ice, that is, to use the good conductivity of conductive concrete to melt ice and snow by the heat generated after applying an AC or DC electric field.

One is to heat the car. Representative products include the de-icing vehicle called "Heating King" produced by Freetech Technology Co., Ltd. The car heats the ice and snow with heating plates. The heating plate uses liquefied petroleum gas as fuel and heats the road surface with 100% heat radiation heating. The heating plate is divided into 4 zones, which can be controlled and evenly heated.

Physical melting methods work better for small snowfall and thin ice. When the amount of snow is large, all the snow has to be melted, the melting speed is slow, the efficiency is low, and the energy consumption is high. Moreover, there is no way to deal with the large amount of water melted. When the ambient temperature is low, the water will Freeze again, affecting the effect of deicing and snow.

The principle of chemical deicing and snow removal is to spray a certain amount of antifreeze chemical materials on the road surface to reduce the freezing point of ice and snow, melt the ice and snow on the road surface or reduce its strength, and then use other methods to remove it.

One is to sprinkle salt to melt snow and ice. This method is to use salt to lower the freezing point of water, so that the snow will automatically melt. This method has the characteristics of wide source of materials, cheap price, and good effect of melting ice and snow, so it has been widely used. However, the salt removal method has also brought many negative effects to the concrete pavement structure and environment, mainly manifested in problems such as steel fiber corrosion, pavement denudation damage, and environmental pollution. Many countries in the world have caused serious damage to roads and bridges due to the use of deicing salt, and are currently spending huge sums of money on repairs, resulting in huge economic losses.

The mechanical deicing method is to remove ice and snow and remove ice and snow hazards through the direct action of machinery on ice and snow. It has a wide range of applications. At present, there are many types of deicing machines, each with its own strengths.

The main body of the drum-type ice breaker is a cylindrical drum. On the outer surface of the drum, there are orderly arranged horseshoe-shaped shovels. The drum is filled with sand to increase the quality. When the ice breaker is working, it is dragged forward by other vehicles. The shovel breaks up large areas of snow or ice and lifts it off the ground, while being pushed to the side of the road by a shovel equipped behind the mechanism. This mechanism works well on flat roads, but when the road surface is uneven, the effect will be poor, and the blade will seriously damage the road surface.

The deicing-based machinery has a better effect on the snow on the road, because the snow is generally not tightly combined with the road surface and is easy to remove. But when the air temperature is low, the ice turned from snow due to various reasons will be closely combined with the road surface, and the hardness of the ice is very high at this time. Although the damage to the road surface of the equipment is considered when designing the equipment, try Injury to the road surface and damage to equipment can be avoided by controlling the strength or force of the operating equipment. However, if the power of the deicing machine is small, it is impossible to separate the ice from the road surface; and if the force is increased, the road surface will inevitably be damaged.

Contents of the invention

The purpose of the utility model is to provide a microwave deicing vehicle. Using the principle of microwave heating, according to the characteristics of weak microwave absorption ability of ice and strong microwave absorption ability of pavement materials, microwaves penetrate the ice layer to heat the ground connected with ice, and the temperature of the ground surface rises, melting the ice at the joint with the ground surface. Eliminate the binding force between the road surface and the ice layer. After the above steps, use mechanical methods to apply mechanical force to the ice layer to break the ice layer and make the ice layer break away from the ground, making it easier to clear the ice.

The front portion of the crushing ice mechanism is a microwave heater, and the microwave heater and the crushing ice mechanism are connected with the car body, so that the ice heated by the microwave heater can be crushed by the crushing ice mechanism and the cleaning mechanism collects the crushed ice. There are control mechanisms to control the state of each mechanism.

Wheels are installed on the bottom of the microwave heater, and springs are used to connect the heater and the vehicle body. When the spring was the original length, the wheels of the microwave heater were flush with the lower edge of the wheels of the car body. In this way, when the microwave deicing vehicle is working on the road, when passing through the concave part of the road surface, due to the influence of its own weight, the heater will drop a certain distance, and the wheels will keep in contact with the road surface; when passing through the convex part of the road surface, the spring will be compressed to heat In any case, the distance between the microwave heater and the road surface is always the distance between the lower edge of the microwave heater and the wheels of the microwave heater itself. It is guaranteed that the distance remains basically unchanged. In order to prevent the road from colliding with the microwave heater, a rubber ring is installed on the edge of the box. A baffle is arranged outside the microwave heater, and the baffle is connected with the vehicle body. The microwave heater can only move up and down relative to the car body, ensuring the position of the microwave heater.

Behind the microwave heater is an ice crushing mechanism. At least two supports are connected with the vehicle body, and the supports are movably connected with the shaft. The cam is connected to the shaft and rotates with the shaft. The cam is in contact with the shaft, the shaft is connected with two uprights, and there are springs on the uprights, and the ice crushing shovels are connected with the uprights to form a group of ice shovels, and at least one group of ice shovels is installed on the car body. The speed change mechanism is connected with the shaft. The speed change mechanism is powered by a power source and uses a cam mechanism to control the movement. When the cam rotates, the position of the ice-crushing shovel is gradually raised. When the cam turns to the sudden change in radius on the cam, the ice-crushing shovel will be under the action of the spring force. , falling rapidly, breaking the ice on the road.

The cleaning mechanism is behind the ice crushing mechanism; the deicing shovel is used in front of the ice harvesting conveyor belt, and the conveyor belt is connected to the car body by connecting rods and pulleys. The broken ice cubes are received on the ice harvesting conveyer belt, and with the movement of the conveyer belt, the ice is conveyed to the collection box, and the control mechanism is connected to the vehicle body. Because the ice at this time has been basically separated from the road surface due to heating, and there is no binding force, the force required to crush the ice is much smaller than that of purely mechanical methods.

The utility model has the advantages that: it can grasp the key of deicing, and use microwave heating method to thaw the frozen joint between the ice layer and the ground, so as to separate the ice from the ground; To achieve the purpose of deicing and cleaning the road surface. It also has the advantages of no chemical pollution, environmental protection, high deicing efficiency, and no damage to the ground.

Detailed ways

Embodiment 1: The overall structure of a microwave deicing vehicle is mainly composed of a vehicle body 2, a power source 17, a microwave heater 1, an ice crushing mechanism 3 and a cleaning mechanism.

The car body 2 is the fixed foundation of each equipment. The power source 17 is undertaken by the internal combustion engine 19 and the generator 30. The internal combustion engine 19 provides the power for the movement of each mechanism, and drives the generator 30 to generate electricity to provide power to the microwave heater 1. The front portion of the ice-breaking mechanism 3 is a microwave heater 1, and the microwave heater 1 and the ice-breaking mechanism 3 are connected with the car body 2, so that the ice heated by the microwave heater 1 can be crushed in time. The wheels 8 are connected to the vehicle body 2 .

Choose a radiant heater. In order to evenly heat the road surface, an existing radiant microwave heater called a near-field microwave oven is selected among the radiant heaters, the structure of which is shown in Figure 4.

The energy of the microwave heater 1 is radiated by slots 50, which are several half-wavelength resonant slots opened on a metal plate. The arrangement of the slots 50 is shown in FIG. 5 . The slots 50 are powered by the antenna chamber 45 , and the antenna chamber 45 transmits energy through the waveguide 44 above and the cross antenna 46 symmetrically placed on the antenna chamber 45 . Through the radiation of the slots 50, the microwaves can be radiated to the road surface under the box body more uniformly and heat the road surface. In order to prevent dust, dirt, etc. from entering the antenna chamber 45 through the slot 50 and affecting the normal operation of the microwave heater 1, a ceramic plate 41 is installed under the slotted metal plate 42, because ceramics belong to insulator materials, and usually the microwave power absorbed by it It is very small, and most of the microwaves will pass through the ceramics, so as to achieve the purpose of dust prevention without affecting the transmission of microwaves. A certain distance is reserved between the lower edge of the box body 47 and the ceramic plate 41 to protect the ceramic plate 41 . The microwave tube 43 is connected to the waveguide 44 .

Controlling the distance between the microwave heater 1 and the road surface is a problem since the road surface and the ice on the road surface will not be smooth. Four wheels 5 are installed on the bottom of the microwave heater 1 , and springs 7 are used to connect between the microwave heater 1 and the vehicle body 2 . When the spring 7 was the original length, the wheel 5 of the microwave heater 1 was flush with the lower edge of the wheel 8 of the vehicle body 2 . Microwave deicing vehicle works on the road like this, when passing through the recess of road surface, due to the influence of self-weight, microwave heater 1 can drop a certain distance, and four wheels 5 can keep contacting with road surface; Spring 7 can be compressed, and microwave heater 1 can rise a certain distance, and four wheels 5 still can keep contacting with road surface; The distance between the wheels 5 of the microwave heater 1 itself. It is guaranteed that the distance remains basically unchanged. In order to prevent the road from colliding with the microwave heater 1, a rubber ring 40 is installed on the edge of the box body. A baffle 31 is connected to the outside of the microwave heater 1, so that the microwave heater 1 can only move up and down relative to the vehicle body 2, ensuring the position of the microwave heater 1.

The transmission mechanism 23 is connected to the shaft 21 . The speed change mechanism 23 is provided with rotational power by the power source 17, and adopts a cam mechanism to control the movement. When the cam 20 rotates, the position of the ice-breaking shovel 4 is gradually raised. Under the action of the force of the spring 6, it will drop rapidly and crush the ice on the road.

Because the ice at this time has basically separated from the road surface due to heating, there is no binding force, and the power needed to crush the ice is much smaller than that of pure mechanical methods. The ice that has been separated from the road surface can protect the road surface from mechanical damage.

The cleaning mechanism utilizes roller brushes to sweep away the ice that has been broken and separated from the road surface. In order to prevent part of the ice from being separated from the road surface and to facilitate ice collection, a deicing shovel 10 is used in front of the ice collection conveyor belt 11. Under the combined action of the ice shovel 10 and the roller brush of the cleaning device 9, the broken ice cubes are received on the ice harvesting conveyor belt 11, and the ice is conveyed to the collection box 12 with the movement of the conveyor belt 11, and the control mechanism 13 is connected to the on the body 2.

Embodiment 2: the crushing ice mechanism 3 has the ice and snow crushing mechanism as shown in Figure 6, and the vehicle runner has at least two groups of wheels before and after, and the ice and snow crushing mechanism is installed after the microwave heater between the two groups of wheels at the front of the rear wheel. The outer circumference of 63 is covered with taper nail 62, and the width of ice roller 63 matches with the width of microwave heater heating ground. The structure of one side of the ice roller 63 is as follows: through the swing rod 69, the connecting hinge seat 66 is connected with the vehicle body 67, the oil cylinder 68 is connected with the crank 64, the connecting rod 70 through the shaft, the crank 64 is connected with the connecting hinge seat 65 through the shaft, and the The hinge seat 65 is connected with the vehicle body 67, and the connecting rod 70 is connected with the fork 69 through a shaft. On the other side of the ice roller 63 there is the same structure as described above. The piston rod extension of oil cylinder 68 makes crank 64 connecting rod 70 and fork 69 triangular shape, and ice roller 63 contacts with the icing 61 on the road 60. disengagement. The ice roller 63 rotates and crushes the ice 61 with the cone nail 62 on the self-weight ice roller 63 . The piston rod of the oil cylinder 68 is withdrawn, so that the crank 64 and the connecting rod 70 are pulled up, and the fork 69 is driven to rotate with the axis connecting the hinge seat 66 as the center of a circle, and the ice roller 63 is out of contact with the icing 61 on the road 60.
