Description

Technical Field

[0001] This application relates to the field of road de-icing technology, and in particular to a de-icing device. Background Technology

[0002] After freezing rain and blizzards occur in winter, snow accumulates on city roads. Due to the passage of vehicles and pedestrians, the snow on the road surface is repeatedly compacted to form an ice layer. The ice layer is solid, and if the temperature does not rise, it is difficult to melt. The solid ice layer also increases the difficulty of de-icing and snow removal, causing a lot of inconvenience to people's travel.

[0003] Existing de-icing methods include manual de-icing, chemical de-icing, and mechanical de-icing. Among them, the main method of chemical de-icing is to spray de-icing agents. However, during the spraying process, due to the solidity of the road ice layer, the de-icing agent can only be sprayed to the surface of the ice layer and cannot reach its depth. This results in a small actual contact area between the de-icing agent and the road ice layer, making it difficult to achieve high de-icing efficiency. Utility Model Content

[0007] In some embodiments, the ice-breaking support includes: an ice-breaking support plate, one end of which is rotatably mounted to a receiving groove; and a telescopic rod, one end of which is connected to the ice-breaking support plate and the other end of which is connected to the receiving groove, the telescopic rod being used to drive the ice-breaking support plate to rotate along the receiving groove.

[0008] In some embodiments, the ice-breaking body has a heating element at one end near the icy road.

[0009] In some embodiments, the spraying mechanism includes a storage structure located at the vehicle body. The storage structure has a storage cavity for containing de-icing agent. The storage structure has multiple spray holes at one end near the icy road for the de-icing agent to pass through.

[0010] In some embodiments, the spraying mechanism further includes a pressing structure located within the storage cavity. At least a portion of the pressing structure has a stroke approaching and moving away from the icing orifice. The pressing structure includes: a pressing plate; and a pressing rod, which is telescopically configured. One end of the pressing rod is mounted on the side of the storage structure away from the icing road, and the other end of the pressing rod is mounted on the pressing plate. The pressing rod is used to drive the pressing plate towards and away from the icing orifice.

[0011] In some embodiments, the pressure plate is provided with a plurality of protrusions on the side near the discharge hole, and each protrusion is provided corresponding to each discharge hole.

[0012] In some embodiments, the storage structure includes a bottom wall for proximity to the icy road, with each dispensing hole located on the bottom wall. The spraying mechanism also includes a cleaning structure. The inner wall of the storage cavity is provided with an installation groove, and the cleaning structure is at least partially located within the installation groove. The cleaning structure includes: a cleaning scraper, the bottom of which is attached to the bottom wall, for pushing the de-icing agent from the bottom wall to the dispensing holes; and a telescopic push arm, one end of which is connected to the wall of the installation groove, and the other end of which is connected to the cleaning scraper for driving the cleaning scraper to move along the bottom wall.

After the pretreatment mechanism softens the surface ice layer, the ice-breaking body of the ice-breaking mechanism reciprocates along a direction close to or away from the icy road to break through the ice layer and achieve the ice-breaking effect. An ice-breaking support is protruding from the ice-breaking body, which follows the reciprocating motion of the ice-breaking body, thereby breaking up a larger area of ​​ice. Subsequently, the spraying mechanism sprays de-icing agent onto the road surface. The de-icing agent can contact the broken ice layer, entering the interior of the broken ice layer, resulting in a larger contact area with the ice layer. This improves the melting efficiency of the ice layer and allows for more efficient use of the de-icing effect, reducing the amount of de-icing agent required. Attached Figure Description

[0027] A. First direction. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Existing de-icing methods include manual de-icing, chemical de-icing, and mechanical de-icing. Among them, the main method of chemical de-icing is to spray de-icing agents, which include solid de-icing salt. During the spraying of de-icing salt, due to the solidity of the road ice layer, the de-icing salt can only be sprayed to the surface of the ice layer and cannot reach its depths. This results in a small actual contact area between the de-icing salt and the road ice layer, and it can only melt the surface ice. If the entire ice layer needs to be melted, the amount of de-icing salt used needs to be increased. On the one hand, this increases the amount of de-icing salt used, raising costs and impacting the environment. On the other hand, spraying de-icing salt on the surface of the ice layer makes it difficult to penetrate into the ice layer, resulting in low actual de-icing efficiency.

[0030] Please refer to Figures 1 to 4 To address the aforementioned technical problems, this application proposes a de-icing device 1000 for de-icing icy roads. The de-icing device 1000 includes a vehicle body 1, a pretreatment mechanism 2, a spraying mechanism 3, and an ice-breaking mechanism 4. The vehicle body 1 has a travel distance along a first direction; the pretreatment mechanism 2 is located on the vehicle body 1 and includes a heating element 21 for contacting the surface of the icy road; the spraying mechanism 3 is spaced apart from the pretreatment mechanism 2 on the vehicle body 1 along the first direction and sprays de-icing agent onto the icy road; and the ice-breaking mechanism 4 includes an ice-breaking body 41 and an ice-breaking branch 42. The ice-breaking body 41 is located on the vehicle body 1, between the pretreatment mechanism 2 and the spraying mechanism 3. The ice-breaking branch 42 protrudes along the periphery of the ice-breaking body 41 on its surface. At least a portion of the ice-breaking body 41 has a travel distance towards or away from the icy road.

[0031] Understandably, the pretreatment mechanism 2 includes a heating element 21, which is used to contact the surface of the icy road to melt part of the surface ice layer, making part of the surface ice layer soft, which facilitates the subsequent de-icing by the ice-breaking mechanism 4. In addition, the ice-breaking mechanism 4 is located between the pretreatment mechanism 2 and the spraying mechanism 3. Therefore, after the pretreatment mechanism 2 softens the surface ice layer, the ice-breaking body 41 of the ice-breaking mechanism 4 moves back and forth in the direction close to or away from the icy road to break through the depth of the ice layer to achieve the ice-breaking effect. Furthermore, the ice-breaking body 41 is provided with an ice-breaking support 42, which can follow the reciprocating movement of the ice-breaking body 41, thereby driving the breaking of a larger area of ​​ice layer. Subsequently, the spraying mechanism 3 sprays de-icing agent onto the road surface. The de-icing agent can contact the broken ice layer and enter the interior of the broken ice layer, with a larger contact area with the ice layer. While improving the melting efficiency of the ice layer, it can make fuller use of the de-icing effect of the de-icing agent and reduce the amount of de-icing agent used.

[0032] To ensure the heating effect of the pretreatment mechanism 2, in some embodiments, the pretreatment mechanism 2 further includes a movable arm. One end of the movable arm is movably disposed at the vehicle body 1, and the other end of the movable arm is connected to the heating part to drive the heating part to contact the surface of the ice layer, so as to initially melt the surface of the ice layer, soften the surface ice layer, and facilitate the ice-breaking body 41 to penetrate into the interior of the ice layer, thereby achieving a better ice-breaking effect.

[0033] In the embodiments of this application, the heating unit includes an electric heating device, such as a soldering iron or a heating wire, which is capable of generating heat by passing electricity. The temperature of the electric heating device can be controlled by adjusting the current, adapting to different de-icing scenarios and improving the versatility of the de-icing device 1000 in this application. For example, for thicker ice layers, the current can be increased to raise the temperature of the electric heating device, thereby rapidly melting the surface ice. For thinner ice layers, the current can be reduced to lower the temperature of the electric heating device, achieving energy savings while melting the ice surface. In other embodiments, the heat source for the heating unit also includes hot water, burning charcoal, etc., which are not limited herein.

[0034] To further enhance the ice-breaking effect, please refer to... Figure 2 and Figure 3The ice-breaking body 41 includes: an ice-breaking column 411, which is rotatably mounted on the vehicle body 1. The ice-breaking column 411 includes a first column segment 4111, a second column segment 4112, and a telescopic column segment 4113. The first column segment 4111 is used to be assembled to the vehicle body 1. The surface of the second column segment 4112 is provided with a receiving groove 4112a, which is used to receive the ice-breaking support 42. The telescopic column segment 4113 is located between the first column segment 4111 and the second column segment 4112, and the telescopic column segment 4113 is used to drive the second column segment 4112 to approach and move away from the first column segment 4111. The ice-breaking head 412 is mounted on the second column segment 4112 at one end that is close to the icy road. The ice-breaking head 412 is conical.

[0035] Understandably, since the ice-breaking column 411 is rotatably mounted on the vehicle body 1, the conical ice-breaking head 412 rotates along with the ice-breaking column 411. Furthermore, the ice-breaking column 411 includes a telescopic column section 4113. Therefore, in the actual ice-breaking process, the rotating conical ice-breaking head 412 can easily break through the hard ice layer. Driven by the telescopic column section 4113 in its extension direction, the ice-breaking head 412 can gradually penetrate into the ice layer to break and shatter the ice on the road surface, achieving a better ice-breaking effect. The ice-breaking column 411 includes a first column section 4111, a second column section 4112, and a telescopic column section 4113. The first column section 4111 is rotatably connected to the vehicle body 1. The surface of the second column section 4112 is provided with a receiving groove 4112a to accommodate the ice-breaking support 42. The second column section 4112 is positioned close to the ground, allowing the ice-breaking support 42 to also penetrate into the ice layer to assist in ice breaking and achieve a better ice-breaking effect.

[0036] In some other embodiments, the telescopic column segment 4113 includes an electrically operated telescopic rod 422 for driving the second column segment 4112 to move in directions toward and away from the first column segment 4111. In order to achieve the effect of buffering and shock absorption, a spring is also connected between the first column segment 4111 and the second column segment 4112. Since the second column segment 4112 and the ice-breaking head 412 are easily subjected to the reaction force from the ice during the ice-breaking process, the spring can buffer the impact between the first column segment 4111 and the second column segment 4112, which facilitates the operation of the electrically operated telescopic rod 422.

[0037] Furthermore, the ice-breaking support 42 includes an ice-breaking support plate 421 and a telescopic rod 422. One end of the ice-breaking support plate 421 is rotatably mounted to the receiving groove 4112a. One end of the telescopic rod 422 is connected to the ice-breaking support plate 421, and the other end of the telescopic rod 422 is connected to the receiving groove 4112a. The telescopic rod 422 is used to drive the ice-breaking support plate 421 to rotate along the receiving groove 4112a. It can be understood that the ice-breaking support plate 421 has an installation end and a free end. Its installation end is rotatably mounted to the receiving groove 4112a, and its free end is driven by the telescopic rod 422, allowing it to move closer to or further away from the receiving groove 4112a. Therefore, during the operation of the ice-breaking mechanism 4, the ice-breaking support plate 421 extends into the ice layer as the second column segment 4112 penetrates, and then the telescopic rod 422 extends, so that the ice-breaking support plate 421 moves away from the receiving groove 4112a and breaks the ice layer around the second column segment 4112. As the second column segment 4112 rotates, the ice-breaking support plate 421 also rotates to break the ice layer around it. As the second column segment 4112 moves closer to and away from the first column segment 4111, the ice-breaking support plate 421 can break the ice layer along the movement direction of the second column segment 4112 to achieve large-area ice breaking.

[0038] In the embodiments of this application, the number of ice-breaking support plates 421 is set to multiple, and each ice-breaking support plate 421 can share the ice-breaking pressure to reduce the overall ice-breaking resistance, making the de-icing device 1000 more durable and further improving the ice-breaking efficiency.

[0039] To further increase the efficiency of ice breaking, a heating element is provided at one end of the ice breaking body 41 that is close to the icy road. On the one hand, the heating element can provide heat to the ice breaking body 41, so that the ice breaking body 41 has a certain temperature and can melt the ice layer around it, so that the ice breaking body 41 can break the ice. On the other hand, the heat provided by the heating element can melt the ice that is stuck to the ice breaking body 41, thereby preventing the ice breaking body 41 from carrying ice and affecting the ice breaking efficiency.

[0040] Please refer to Figure 4The spraying mechanism 3 includes a storage structure 31 located at the vehicle body 1. The storage structure has a storage cavity 311 for containing de-icing agent. The storage structure 31 has multiple spray holes 312 at one end near the icy road, and each spray hole 312 is used for the de-icing agent to pass through. In the embodiments of this application, the storage structure 31 is used to store the de-icing agent, which falls through the dispensing hole 312. When the ice-breaking mechanism 4 breaks the ice layer on the surface of the icy road, the exposed area formed by the broken ice layer increases, the ice layer is also broken and loosened by the ice-breaking mechanism 4, and can be exposed to the depth of the ice layer. At this time, the vehicle body 1 moves along the first direction, the storage structure 31 moves above the broken ice layer, and the de-icing agent falls from the dispensing hole 312. It can not only contact the broken ice layer on the surface, but also contact the interior of the broken ice layer. On the one hand, it can make the de-icing agent evenly distributed to all parts of the ice layer, so as to increase the contact area between the ice layer and the de-icing agent and improve the efficiency of ice melting. On the other hand, since the ice-breaking mechanism 4 can loosen the ice layer, it can also reduce the hardness of the ice layer to a certain extent, so that the falling de-icing agent can be wrapped by the ice layer, further increasing the contact area between the de-icing agent and the ice layer and improving the efficiency of ice melting.

[0041] It is understandable that de-icing agents generally include de-icing salt. In actual production, transportation and storage, de-icing salt may become damp and clump together. Clumped de-icing salt is difficult to control the amount used and is easy to be overused, which can cause harm to the environment.

[0042] Therefore, in this application, the spraying mechanism 3 also includes a pressing structure 32, which is located in the storage cavity 311. At least a portion of the pressing structure 32 has a stroke that approaches and moves away from the icing hole 312. The pressing structure 32 includes: a pressing plate 321; and a pressing rod 322, which is telescopically arranged. One end of the pressing rod 322 is installed on the side of the storage structure 31 away from the icing road, and the other end of the pressing rod 322 is installed on the pressing plate 321. The pressing rod 322 is used to drive the pressing plate 321 to approach and move away from the icing hole 312. The de-icing agent is located between the pressing structure 32 and the dispensing hole 312. The pressing rod 322, which is telescopically set, pushes the pressing plate 321 closer to the dispensing hole 312, thereby pushing the de-icing agent through the dispensing hole 312. During this process, some clumps of de-icing agent can be crushed under the pressure of the pressing plate 321, forming small pieces of de-icing agent that can pass through the dispensing hole 312. By controlling the size of the dispensing hole 312, the volume of the de-icing agent being dispensed can be controlled, thereby meeting the de-icing needs of ice layers of different thicknesses. This ensures high efficiency in de-icing while being environmentally friendly.

[0043] Please continue to refer to Figure 4To achieve better pressing effect, the pressing plate 321 is provided with multiple protrusions 3211 on the side near the dispensing hole 312, with each protrusion 3211 corresponding to a dispensing hole 312. When the pressing plate 321 approaches the dispensing hole 312, the multiple protrusions 3211 move synchronously to cut the clumps of de-icing agent and squeeze the de-icing agent to the dispensing hole 312, so that the de-icing agent can fall from the dispensing hole 312.

[0044] In some embodiments, the storage structure 31 includes a bottom wall for proximity to the icy road, and each sprinkling hole 312 is located at the bottom wall. The spraying mechanism 3 also includes a cleaning structure 33. The inner wall of the storage cavity 311 is provided with a mounting groove 311a. The cleaning structure 33 is at least partially located in the mounting groove 311a. The cleaning structure 33 includes: a cleaning scraper 331, the bottom of which is attached to the bottom wall, and the cleaning scraper 331 is used to push the de-icing agent at the bottom wall to the sprinkling hole 312; and a push arm 332, which is telescopically configured. One end of the push arm 332 is connected to the groove wall of the mounting groove 311a, and the other end of the push arm 332 is connected to the cleaning scraper 331, for driving the cleaning scraper 331 to move along the bottom wall. It is understandable that the bottom wall has a sprinkling hole 312. After some of the de-icing agent located on the bottom wall flows out through the sprinkling hole 312, the remaining de-icing agent remains on the bottom wall. In the embodiments of this application, the spraying mechanism 3 also includes a cleaning structure 33. The cleaning scraper 331 can sweep the de-icing agent remaining on the bottom wall to the sprinkling hole 312, so as to completely remove and use up the de-icing agent. On the one hand, it achieves cleaning of the storage cavity 311, and can push the de-icing agent in the corners to the sprinkling hole 312. On the other hand, it can also push the uncrushed de-icing agent to the sprinkling hole 312, so that the pressing mechanism can crush it, thereby ensuring the utilization rate of the de-icing agent.

[0045] For more details, please refer to... Figure 4 In some embodiments of this application, the storage structure 31 includes a side wall connected to a bottom wall. An installation groove 311a is located on the side wall. A portion of the cleaning structure 33 is located within the installation groove 311a. The cleaning scraper 331, driven by a push arm 332, can move from inside the installation groove 311a to outside. The push arm 332 extends and retracts to push the cleaning scraper 331 to push the de-icing agent. The structure is simple and easy to implement. When the pressing structure 32 is running, the cleaning scraper 331 remains within the installation groove 311a to avoid the movement of the pressing structure 32.

[0046] Furthermore, a scraper head 3311 is provided on the side of the cleaning scraper 331 near the bottom wall. The scraper head 3311 is designed to fit snugly against the bottom wall. The scraper head 3311 is made of any one of the following materials: silicone, rubber, TPE, or TPR. In this application, the scraper head 3311 is made of a flexible material, increasing the contact area with the bottom wall. The scraper head 3311 can fit snugly against the bottom wall, thus preventing the de-icing agent from sticking to the bottom wall during material pushing. Moreover, silicone, rubber, TPE, and TPR materials all possess good wear resistance and durability, allowing for repeated use and enhancing the durability of the cleaning scraper 331.

[0047] Please refer to Figure 4 The spraying mechanism 3 also includes a cover 34, which is rotatably mounted to each of the spray holes 312. The cover 34 rotates to close or open the spray holes 312. In the embodiments of this application, the cover 34 is used to open and close the spray holes 312, thereby controlling the amount of de-icing agent used and ensuring the rational use of the de-icing agent, so as to achieve efficient de-icing while protecting the environment.
