Description

Technical Field

[0001] The invention relates to the field of road obstacle clearing, in particular to a road obstacle clearing device. Background Art

[0002] Roadblock clearing refers to the removal of obstacles on the road to ensure smooth and safe road traffic. These obstacles will hinder road traffic and driving safety and must be removed in a timely manner. Roadblock clearing work includes the obligation and responsibility to protect road traffic safety, especially on busy roads and highways. The importance of roadblock clearing work cannot be underestimated. Only by ensuring that there are no obstacles on the road can traffic flow smoothly and traffic accidents be avoided.

[0003] Obstacles naturally formed by extreme weather such as road icing and thick snow are also common road obstacles. For example, large-scale heavy snowfall in areas with low temperatures will seriously affect road driving and driving safety. Therefore, special equipment is needed to clear such obstacles. Existing tow trucks are slow to run due to the weight of the vehicle and the accumulation of snow and water generated after clearing. Failure to process the melted snow and water under extremely low temperature conditions will cause secondary freezing of the road surface. Therefore, a large amount of snow-melting agent can only be spread to suppress this situation. However, snow-melting agent is harmful. The residue of snow-melting agent can corrode the road surface and automobile rubber tires, and after the ice and snow melt, it will flow into the plant soil on both sides of the road, causing secondary pollution. In order to improve the snow removal efficiency and reduce the use of snow-melting agent, a road obstacle clearing equipment is proposed to solve the above problems. Summary of the invention

[0015] Furthermore, the water inlet pipe of the delivery pump member passes through and extends to the interior of the clean water tank, and the water outlet pipe of the delivery pump member is fixedly connected to the steam boiler.

[0016] In summary, the beneficial effects of the present invention are: 1. Use a rolling brush to break up the accumulated ice and snow on the road, and use the snow melting component to fit the residual ice on the ground, break up the ice surface by melting it with hot steam at high temperature, and then use the suction component to suck the melted snow water and debris into the sewage tank for storage. At the same time, a filter is installed on the baffle plate in the sewage tank to continuously soften the passing snow water and guide it to the connecting valve pipe, and finally enter the clean water tank for static. The delivery component delivers antiscalant into the clean water tank to further soften the water quality, reduce the number of maintenance and cleaning, and reduce equipment operation. It reduces the cost of production and has a certain protective effect on the boiler metal, preventing the corrosion of metal by dissolved oxygen and other anions, and has a passivation function on the boiler body. The scale inhibitor can also release heat when reacting with water, which increases the water temperature and further reduces the energy consumption of the steam boiler. The debris slides through the guide seat and passes through the baffle plate to accumulate under the buoyancy ball. During the snow melting process, the push gradually increases to push the buoyancy ball upward. After the buoyancy ball moves and contacts the proximity sensor, the unloading valve opens to discharge the debris into the delivery box for use in paving the road.

[0017] 2. After separation, the debris in the melted snow will be stored in the delivery box. When the tip of the sand and gravel needs to be rubbed, the water in the sewage tank is controlled to be introduced into the reciprocating box. At this time, the sliding support plate moves downward under the gravity of the reciprocating box, and the telescopic spring is squeezed and deformed. When the telescopic spring is compressed to the limit, the sewage in the reciprocating box can be controlled to stop being injected, and the sewage can be quickly flowed from the collection pipe into the collection box. Therefore, the water outlet aperture of the reciprocating box in this embodiment is large or even close to the cross-sectional size of the reciprocating box. Water quickly flows from the reciprocating box into the collection box. Under the elastic force of the spring, the sliding support plate quickly bounces upward, and the sand and gravel can also quickly bounce above the sliding support plate. Friction occurs between the sand and gravel and the abrasive layer. The water in the reciprocating box and the collection box circulates multiple times, and the sand and gravel can be rubbed against the abrasive layer multiple times, so that the sharp end of the sand and gravel is smoothed.

[0018] 3. Since the equipment is equipped with a clean water tank to provide water for the steam boiler to generate steam, and the lower space in the delivery box formed by the sliding tray is also filled with natural paving materials such as sawdust and gravel in advance, the equipment can be directly used for snow melting operations, and in the process of snow melting, the sucked-in melted snow is subsequently utilized to improve endurance, increase the area and kilometers that the equipment can melt snow, and there is no need to store the snow water separately and then discharge it, which reduces the number of times the equipment needs to be replenished and stopped, thereby improving the snow melting efficiency. In addition, since the equipment can remove obstacles on the road, absorb melted snow to prevent secondary icing, and lay dry paving materials to avoid slipping, it can reduce dependence on snow melting agents, thereby protecting roads, vehicle chassis and tires, and has a significant environmental protection effect.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figures 1 to 9As shown, in the embodiment 1 of the present invention, a road obstacle cleaning device is provided. The roller brush 2 can physically break up the icy road surface or muddy road section, and the clean water tank 5 is pre-filled with clean water to provide clean water for the steam boiler 6. The hot steam generated by the steam boiler 6 is transported to the first steam pipe 61 after being heated. One end of the "T"-shaped steam pipe 61 can be connected to two connecting pipe seats 122 at the same time, so that the hot steam is evenly dispersed between the top cover 121 and the steam bottom cover 123, and discharged to the ice along the steam holes 124 evenly distributed at the bottom of the steam bottom cover 123. The snow road surface is liquefied in all directions, and the muddy road section can also be dried. The electric push rod 120 pushes the steam bottom cover 123 to contact the ground to transfer hot steam. During the treatment process, the vehicle continues to move through the suction fan 3 and the suction pipe 31 to suck in the wastewater, and the delivery pipe 32 is transported to the inside of the sewage tank 4. Since the air outlet pipe 33 is set above the delivery pipe 32, and a partition net is installed in the delivery pipe 32, the sucked treated material will be transported through the delivery pipe 32 and part of the positive pressure wind will enter the delivery box 11 along the air outlet pipe 33.

[0023] It should be noted that, if the ice and snow roadblock is to be processed, the original gravel, sand and wood chips on the road surface will be sucked in together with the ice and snow after melting, so the processed materials entering the sewage tank 4 are mainly sewage and debris, and the baffle plate 43 is provided with a waste groove near the discharge valve 47, and the baffle plate 43 and the side opposite to the inner wall of the sewage tank 4 form a narrow and long cavity, and a protrusion is fixedly installed on the outer surface of the baffle plate 43 and the inner wall of the sewage tank 4 to limit the buoyancy ball 46. When the sewage and debris enter the sewage tank 4, they will flow along the guide seat 41. After sliding down to the waste trough, the snow water will be temporarily stored on the other side of the baffle plate 43 through the filter element 44 after accumulating to a certain height. The filter element 44 can perform the first filtering treatment on the snow water to intercept the calcium and magnesium ions in the water, thereby fundamentally reducing the hardness of the water. Then, it will enter the interior of the clean water tank 5 through the connecting valve pipe 8. A delivery component 9 is also provided on the top of the clean water tank 5 to deliver scale inhibitors to perform the second softening treatment process on the filtered snow water. After standing and softening, the softened water will be delivered to the steam boiler 6 through the delivery pump 13.

[0024] The debris will accumulate under the buoyancy ball 46 after passing through the waste trough. The buoyancy ball 46 can block sewage and debris and gradually move up with the accumulation. When the debris is accumulated too high, the buoyancy ball 46 will touch the proximity sensor 45. After the proximity sensor 45 is under pressure, it will transmit an electrical signal to the controller 48. The unloading valve 47 is an electromagnetic unloading valve 47. Then the controller 48 controls the unloading valve 47 to open and discharge debris such as gravel, sand and wood chips into the delivery box 11. Then the buoyancy ball 46 falls back to the starting position above the protrusion.

[0025] Embodiment 2 of the present invention is a road obstacle clearing equipment. On the basis of embodiment 1, it should be noted that dry gravel, sawdust and other natural paving materials are stored in advance in the lower half area of ​​the delivery box 11. During the snow melting process, they can be continuously and evenly discharged to the snow-melted road surface through the electromagnetic discharge pipe 117, so as to absorb residual moisture, increase road friction and prevent the road surface from refreezing due to residual moisture, thereby reducing the use of snow-melting agents, avoiding pollution and damage to the environment and the road surface by snow-melting agents, and thus improving the service life of the road surface. In addition, because the equipment can handle road obstacles, absorb and recover the treated materials, and integrate the road paving, it avoids the need for maintenance personnel to subsequently sprinkle snow-melting agents while cleaning the road surface, thereby achieving green environmental protection and efficiency in handling roadblocks.

[0026] In addition, debris such as gravel, sand, and branches generated by melting snow will also enter the delivery box 11 through the unloading valve 47 and be isolated and stored in the upper half area by the sliding pallet 114, avoiding the problem of clogging of the electromagnetic discharge pipe 117 caused by the mixing of the fillings containing water and the fillings in the lower half area.

[0027] Embodiment 3 of the present invention is a road obstacle clearing device. On the basis of embodiment 1 or 2, the heat conductive block 72, the heat conductive pipe 73 and the heat conductive net 116 are all made of copper material and can conduct heat well. In addition, the outside of the heat conductive pipe 73 is coated with a heat insulating sleeve layer to block heat. After the steam boiler 6 generates hot steam, a part of the gas will enter the inside of the connecting head 7 along the second steam pipe 62. After the hot steam contacts the heat conductive block 72 with a lower temperature, it will transfer the heat to the heat conductive block 72. The heat conductive pipe 73 is responsible for connecting the heat conductive net 116 and the heat conductive block 72, so that the heat is finally transferred to the heat conductive net 116. After the heat transfer is completed, the hot steam will be converted into liquid. A one-way valve pipe 71 is also provided inside the connecting head 7 to guide the water to the inside of the reflux chamber 42. The water inside the reflux chamber 42 will flow into the sewage tank 4 through the overflow hole on the guide seat 41 and re-combine to supply water to the steam boiler 6.

[0028] In addition, the heat conducting net 116 is rectangular in shape. The air outlet pipe 33 is arranged above the heat conducting net 116 without affecting the feeding of the discharge valve 47. During the continuous suction of snow water by the suction fan 3, part of the snow water is filtered in the sewage tank 4 to supply water to the steam boiler 6 again, and the gravel, crushed stone and other debris separated from the melted snow enter the delivery box 11 through the discharge valve 47. The positive pressure wind is blown into the delivery box 11 through the air outlet pipe 33 and forms hot air through the heat conducting net 116 with heat. The moisture-containing debris is dried by high-temperature air drying in preparation for use in filling the road surface.

[0029] Embodiment 4 of the present invention is a road obstacle clearing device. Based on any one of embodiments 1 to 3, the internal gravel and crushed stone are loosened, and the positive pressure wind discharged from the air outlet pipe 33 causes the gravel, crushed stone and frosted layer 115 to collide with each other, and grind the surface during the collision, making the surface of the gravel and crushed stone smoother, avoiding the impact of sharp gravel on car tires, and further improving the safety of driving on icy and snowy roads.

[0030] A support plate 111 is fixedly installed in the delivery box, a sliding support plate 114 is slidably connected in the delivery box, a telescopic spring 112 is fixedly connected to the top of the support plate 111, the top of the telescopic spring 112 is fixedly connected to the bottom of the sliding support plate 114, a discharge port is arranged in the middle of the sliding support plate 114, and a solenoid valve is arranged on the discharge port. The delivery box 11 is also provided with a reciprocating part for controlling the reciprocating motion of the sliding support plate 114, and the reciprocating part includes a reciprocating box 15, a reciprocating box 15 for guiding water in the sewage tank 4 into the reciprocating part. The water pipe 151, the reciprocating plate 152, the collecting box 153, the collecting pipe 155 and the water pump 156 in the reciprocating box 15, the reciprocating plate 152 is fixed below the sliding support plate 114, the reciprocating box 15 is fixed on the reciprocating plate 152, the reciprocating pipe is arranged at the bottom of the reciprocating box, the reciprocating pipe is connected to the collecting box 153, the water pump 156 is arranged in the collecting pipe 155 and the output end of the water pump 156 is connected to the reciprocating box 15, the water pipe 151 is also provided with a solenoid valve, the water pipe 151 and The collecting pipes 155 are all configured as hoses; when it is necessary to rub the tip of the sand and gravel, the water in the sewage tank 4 is controlled to be introduced into the reciprocating box 15, and the sliding support plate 114 moves downward under the gravity of the reciprocating box 15, and the telescopic spring 112 is squeezed and deformed. When the telescopic spring 112 is compressed to the limit, the sewage in the reciprocating box 15 can be controlled to stop injecting, and the sewage starts to flow quickly from the collecting pipe 155 into the collecting box 153. Therefore, in this embodiment, the reciprocating box 15 5 has a large water outlet aperture, even close to the cross-sectional size of the reciprocating box 15, and water quickly flows from the reciprocating box 15 into the collecting box 153. Under the elastic force of the telescopic spring 112, the sliding support plate 114 quickly bounces upward, and the sand and gravel can also quickly bounce above the sliding support plate 114. Friction occurs between the sand and gravel and the frosted layer 115, and the water in the reciprocating box 15 and the collecting box 153 circulates multiple times. After multiple frictions between the sand and gravel and the frosted layer 115, the sharp ends of the sand and gravel are smoothed.

[0031] It should be noted that the drying of the separated filler and the filtration of sewage is a dynamic process. Therefore, the pavement fillers in the clean water tank 5 and the lower half of the delivery box 11 are loaded in advance and used for water supply and pavement treatment during the snow melting process of the first road surface. The corresponding clean water and fillers will also be continuously consumed during the snow melting process, reserving processing time for sewage filtration and drying of fillers.

[0032] Embodiment 5 of the present invention is a road obstacle clearing device. Based on any one of embodiments 1 to 4, a generator 14 is used to provide a power source for each device, and two movable partition boards are arranged inside the vehicle body 1 at the location of the steam boiler 6. The partition boards form an independent space for the steam boiler 6 to distinguish other devices, thereby preventing noise, high temperature and possible dust from affecting other devices.

[0033] In addition, both the delivery box 11 and the clean water tank 5 are provided with feeding pipes for delivering materials, which are used to replenish clean water and road surface fillers. Ventilation grooves are provided on the tops of the sewage tank 4 and the delivery box 11.

[0034] The working principle of the present invention is: The rolling brush 2 is used to roll the road surface to physically break the ice. A snow melting component 12 and a suction component 10 are installed at the bottom of the vehicle body 1. The steam bottom cover 123 is pushed close to the ground by the electric push rod 120. At the same time, the delivery pump 13 pumps the clean water in the clean water tank 5 to the steam boiler 6 to generate hot steam. The hot steam flows from the first steam pipe 61 to the connecting pipe seat 122 and fills the steam bottom cover 123 and the top cover 121. The hot steam flows out along the steam hole 124 and contacts the ice and snow on the ground to melt it. Another part of the steam is transmitted to the connector 7 through the second steam pipe 62, wherein the guide The heat block 72 will absorb heat and transfer it to the heat-conducting network 116 through the heat-conducting pipe 73, and the formed water will enter the reflux chamber 42 through the one-way valve pipe 71 and re-enter the sewage tank 4 through the overflow hole to mix with the sucked snow water, while the suction fan 3 and the suction pipe 31 will continue to suck the melted snow water and the gravel, sand and other debris carried by the road surface and the melted snow and transport them to the sewage tank 4. Since the air supply pipe 33 is arranged above the suction pipe 31 and is provided with a blocking mesh, only wind force enters the delivery box 11 along the air supply pipe 33. At this time, the snow water and debris in the sewage tank 4 will continue to be sucked and transported to the sewage tank 4. The snow water continues to accumulate and is blocked by the baffle plate 43. The snow water overflows the filter element 44 and can intercept the calcium and magnesium ions in the water, so that the water quality is softened, and enters the clean water tank 5 through the connecting valve pipe 8. The delivery component 9 is used to deliver the scale inhibitor to provide a static condition for softening the water quality, and continuously pumps the water to the steam boiler 6 through the delivery pump 13 to generate hot steam. The softened water quality can significantly reduce the generation of scale, avoid rusting of the steam boiler 6 and the pipeline, improve the service life and enable the secondary use of the snow water, thereby solving the problem that the prior art can only store the snow water and then discharge it separately, while the impurities in the snow water are discharged along the The guide seat 41 slides to the bottom of the buoyancy ball 46 and pushes the buoyancy ball 46 up during the accumulation process. A proximity sensor 45 is provided between the baffle plate 43 and the inner wall of the sewage tank 4. After the buoyancy ball 46 contacts the proximity sensor 45, the controller 48 controls the discharge valve 47 to open so that the debris falls into the delivery box 11 to wait for processing. The sliding support plate 114 in the delivery box 11 divides the internal space into two layers, the lower space is pre-filled with dry sawdust, gravel, crushed stone and other natural paving materials that can be used to improve the friction of the road surface, and the upper space is specially used for temporary storage of separated debris. When it is necessary to rub the tip of the sand and gravel, the water in the sewage tank is controlled to be introduced into the reciprocating box. At this time, the sliding support plate moves downward under the gravity of the reciprocating box, and the telescopic spring is squeezed and deformed. When it is necessary to rub the tip of the sand and gravel, the water in the sewage tank 4 is controlled to be introduced into the reciprocating box 15. At this time, the sliding support plate 114 moves downward under the gravity of the reciprocating box 15, and the telescopic spring 112 is squeezed and deformed. When the telescopic spring 112 is compressed to the limit, the sewage in the reciprocating box 15 can be controlled to stop injecting, and the sewage starts to flow quickly from the collection pipe 155 into the collection box 153. Therefore, in this embodiment, the water outlet aperture of the reciprocating box 15 is large or even close to the cross-sectional size of the reciprocating box 15. Water quickly flows from the reciprocating box 15 into the collection box 153. Under the elastic force of the telescopic spring 112, the sliding support plate 114 quickly bounces upward, and the sand and gravel can also be quickly on the sliding support plate 114. When the sand and gravel bounce up, friction occurs between the sand and the frosted layer 115, and the water in the reciprocating box 15 and the collecting box 153 circulates multiple times. After the sand and gravel are rubbed against the frosted layer 115 multiple times, the sharp ends of the sand and gravel are ground flat; and after the sand and gravel are dried, the dried filler is replenished to the lower half layer for road filling, and the snow water is continuously filtered into softened water to provide water for the steam boiler 6, thereby improving the overall endurance of the equipment. There is no need to store and discharge the snow water separately, and it is also possible to protect the road and the surrounding environment without using a large amount of snow melting agents, thereby improving road driving safety, and the snow melting efficiency is further enhanced due to the improvement of endurance, which solves the problems in the prior art that the snow melting range is limited due to the upper limit of snow water storage, and the equipment runs slowly and the snow melting efficiency is reduced due to the increase of the equipment's own weight and the snow water storage weight. It has the characteristics of environmental protection, good endurance and strong snow melting effect.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
