Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile deicing equipment, concretely relates to a handheld automobile vehicle-mounted power supply heating efficient ice melting and ice breaking shovel, and is especially suitable for the emergency treatment when the automobile is trapped in the ice layer due to the road icing and snow accumulation in the winter driving of the special road section. BACKGROUND

[0002] The winter ice and snow weather frequently occurs in the cold region, causes the tire and ground friction force to drop when the automobile travels, the vehicle is prone to skidding and cannot travel, and seriously affects the traffic order and travel safety. Under the extreme ice and snow and the heavy traffic overlap highway working condition, when the staff executes the traffic construction and rescue work, the short board of the existing deicing technical equipment is highlighted. The traditional deicing equipment such as the deicing shovel truck or handheld deicing shovel mainly relies on the physical mechanical impact mode to realize the ice breaking, however, when facing the thick ice layer, the limitation of these equipment is exposed.

[0003] Although the deicing shovel truck is large in size and seems to have great strength, but its volume becomes the hindrance. In some narrow road sections or the areas with serious traffic congestion, the deicing shovel truck cannot operate flexibly at all, the large vehicle body is difficult to exert the strength in the limited space, and can only sigh at the ice. When the deicing operation is carried out using the handheld deicing shovel, the staff needs to pay a lot of physical strength, and each swing of the shovel needs to consume great strength. The long time high strength work not only makes the staff tired, but also the deicing efficiency is extremely low. In the rescue rescue of the time, the slow deicing speed undoubtedly delays the time, and makes the traffic recovery process become a long way off.

[0004] In addition, the traditional deicing equipment also faces the problem of uneven deicing effect. Due to the randomness of the physical impact, the ice layer in some places may be completely removed, and the thick ice still remains in the adjacent area. This not only affects the overall traffic quality of the road, but also may cause new safety hazards in the vehicle driving process due to the difference of the road friction.

[0005] Although some heating ice melting tools such as heating deicing shovel exist on the market, most of them have design defects and thus many problems, most of them adopt the built-in rechargeable battery power supply, the power consumption is fast, the use time is limited, and the operation continuity is affected; some need to be equipped with power adapter to convert the direct current, the outdoor use is cumbersome, and the convenience is poor; and the heating power is low, the temperature rises slowly, the heat distribution is uneven, the ice melting and ice breaking effect is poor, the deicing difficulty is increased, the task cannot be efficiently completed, the road is not smooth, and the user is disturbed.

[0006] In summary, it is urgent to develop an efficient ice melting and ice breaking tool which is convenient to carry and use, helps to deal with the road icing and snow accumulation problem, improves the ice and snow deicing work efficiency and quality, and guarantees the smooth and safe traffic.

[0044] The middle interlayer 9 inside the shovel head 1 is made of high-temperature-resistant steel material, which provides sufficient rigidity for the shovel head; the resistance wire 7 is uniformly distributed at equal intervals at the front end inside the shovel head, which guarantees the uniformity of heating; after being wrapped with the mica sheet, the resistance wire is fixed between the shovel head and the middle interlayer through high-temperature-resistant glue, which guarantees the position and area of heating.

[0045] The shovel head 1 is made of alumina ceramic or aluminum nitride ceramic material or high-strength insulating material, which has good insulation and high thermal conductivity; the shovel handle 2 is made of polyimide resin material, which has excellent thermal stability, high tensile strength and high insulation performance.

[0046] The connection between the power supply connecting line 3 and the tail of the shovel handle and the automobile power supply port is in a plug-in connection mode, which guarantees reliable connection, facilitates disassembly and installation, and ensures stable power supply during use.

[0047] High-thermal-conductivity resin material is filled between the resistance wire 7 and the shovel head 1 and the middle interlayer 9, so as to improve the heating efficiency.

[0048] The resistance wire 7 is connected with the port at one end of the power supply connecting line 3 through the wires inside the shovel head 1 and the shovel handle 2; the fuse box 4 is connected with the port at one end of the power supply connecting line at the tail of the shovel handle through the wires.

[0049] The wires inside the power supply connecting line 3, the shovel handle 2 and the shovel head 1, the joint of the wires, the connection of the wires and the switch are sealed to prevent water and moisture.

[0050] The shape of the shovel head 1 is wide and flat like a blade to increase the contact area with the ice surface.

[0051] The connection between the shovel head 1 and the shovel handle 2 is detachable, and the end of the resistance wire 7 has enough length to facilitate subsequent maintenance and device replacement.

[0052] In this embodiment, the shovel head 1 is made of some high-temperature-resistant and corrosion-resistant alloy material or ceramic material, which is processed and manufactured into the required structure shape by pressing and forming; the shovel handle 2 is made of polyimide resin material, which is processed and manufactured by cutting and planing; the high-temperature-resistant steel layer 9 in the shovel head 1 is processed and manufactured into the structure shape of the shovel head 1 by pressing and forming according to the structure of the shovel head 1, and is placed in the cavity of the shovel head 1; the resistance wire 7 inside the shovel head 1 is artificially bent into the shape of the blade edge of the shovel head 1 and is evenly distributed at equal intervals to ensure uniform heating.

[0053] The high-heat-conducting resin material is artificially filled between the resistance wire 7 and the steel layer of the shovel head to make the heat generated by the resistance wire conduct faster to the shovel tip, achieving better ice melting and breaking effect. Note that the high-heat-conducting resin material should not overflow to avoid affecting the heat transfer effect.

[0054] The resistance wire 7 is wrapped with mica sheet 10, which is cut into appropriate size and shape to ensure that it can completely cover every part of the resistance wire. When wrapped in multiple layers, the layers should be tightly attached. A small amount of high-temperature-resistant glue can be applied to the edge to stick and fix it. This prevents the resistance wire from contacting the shovel tip or other conductive parts and causing a short circuit. The sheet structure of the mica sheet can further enhance the insulation effect between the resistance wire 7 and the shovel head 1, and also assist in fixing the resistance wire 7 to make it more stable.

In addition to the aforementioned connection with the switch and resistance wire being firm and reliable, the splicing between different wires (if wire extension is required) should also adopt appropriate connection methods, such as using terminal blocks and crimping them with crimping pliers, or welding and then wrapping with insulating tape or heat shrink tubing to ensure good electrical and insulation performance at the connection points.

[0058] When the wire extends into the inside of the shovel head 1, it should also be laid along the reserved space inside the shovel head 1 to avoid exposing the wire and affecting the structural strength and safety of the shovel tip. If the internal space of the shovel head 1 is limited, a flat, flexible wire can be used to better fit the internal shape of the shovel head 1 for wiring. After the wire is connected to the resistance wire 7, the connection should be checked again to ensure that the connection is firm and well-insulated. A small amount of high-temperature resistant glue can be used to fix the connection (be careful not to let the glue come into contact with the heating part of the resistance wire to avoid affecting heat dissipation and insulation) to prevent the connection from loosening due to vibration, collision or other factors of the shovel head 1 during the ice melting and breaking process, and to ensure the normal operation of the entire heating circuit.

[0059] When using this ice-melting and ice-breaking shovel, the operator determines whether to turn on the switch based on the ice thickness. When the ice is thin, the shovel head can be used to physically and mechanically break the ice. When the ice is thick, the operator can first connect the two ports of the power cable 3 to the tail of the shovel handle and the car's power interface, turn on the switch and adjust the power adjustment device according to the ice thickness, hold the shovel handle 2, and bring the cutting edge of the shovel head 1 into contact with the ice, thereby efficiently melting and breaking the ice and solving the problem of vehicles being trapped in ice and unable to break the ice by conventional means.
